Dynamic disorder is a key feature of the complexes of molecular chaperones and their client proteins, and it facilitates the client release towards a folded state or the handover to downstream components. The dynamic nature also implies that a given chaperone can interact with many different client proteins, based on physico-chemical sequence properties rather than on structural complementarity of their (folded) 3D structure. Yet, the balance between this promiscuity and some degree of client specificity is poorly understood. Here, we review recent atomic-level descriptions of chaperones with client proteins, including chaperones in complex with intrinsically disordered proteins, with membrane-protein precursors, or partially folded client proteins. We focus hereby on chaperone-client interactions that are independent of ATP. The picture emerging from these studies highlights the importance of dynamics in these complexes, whereby several interaction types, not only hydrophobic ones, contribute to the complex formation. We discuss these features of chaperone-client complexes and possible factors that may contribute to this balance of promiscuity and specificity.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10323","intvolume":" 8","status":"public","ddc":["547"],"title":"How do chaperones bind (partly) unfolded client proteins?","oa_version":"Published Version","file":[{"checksum":"a5c9dbf80dc2c5aaa737f456c941d964","success":1,"date_updated":"2021-11-23T15:06:58Z","date_created":"2021-11-23T15:06:58Z","relation":"main_file","file_id":"10333","file_size":4700798,"content_type":"application/pdf","creator":"cchlebak","access_level":"open_access","file_name":"2021_FrontiersMolBioSc_Sučec.pdf"}],"publication_identifier":{"eissn":["2296-889X"]},"month":"10","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000717241700001"],"pmid":["34760928"]},"oa":1,"isi":1,"quality_controlled":"1","doi":"10.3389/fmolb.2021.762005","language":[{"iso":"eng"}],"article_number":"762005","file_date_updated":"2021-11-23T15:06:58Z","pmid":1,"year":"2021","acknowledgement":"We thank Juan C.

Extensive studies have identified the key components participating in SL biosynthesis and signalling, whereas the catabolism or deactivation of endogenous SLs in planta remains largely unknown. Here, we report that the Arabidopsis carboxylesterase 15 (AtCXE15) and its orthologues function as efficient hydrolases of SLs. We show that overexpression of AtCXE15 promotes shoot branching by dampening SL-inhibited axillary bud outgrowth. We further demonstrate that AtCXE15 could bind and efficiently hydrolyse SLs both in vitro and in planta. We also provide evidence that AtCXE15 is capable of catalysing hydrolysis of diverse SL analogues and that such CXE15-dependent catabolism of SLs is evolutionarily conserved in seed plants. These results disclose a catalytic mechanism underlying homoeostatic regulation of SLs in plants, which also provides a rational approach to spatial-temporally manipulate the endogenous SLs and thus architecture of crops and ornamental plants.","lang":"eng"}],"type":"journal_article","oa_version":"None","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10326","intvolume":" 7","title":"Catabolism of strigolactones by a carboxylesterase","status":"public"},{"article_processing_charge":"No","day":"25","month":"12","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"citation":{"ama":"Chauve L, Hodge F, Murdoch S, et al.

We have discovered that, in Caenorhabditis elegans, neuronal Heat shock Factor 1 (HSF-1), the conserved master regulator of the heat shock response (HSR)- causes extensive fat remodelling in peripheral tissues. These changes include a decrease in fat desaturase and acid lipase expression in the intestine, and a global shift in the saturation levels of plasma membrane’s phospholipids. The observed remodelling of plasma membrane is in line with ectothermic adaptive responses and gives worms a cumulative advantage to warm temperatures. We have determined that at least six TAX-2/TAX-4 cGMP gated channel expressing sensory neurons and TGF-β/BMP are required for signalling across tissues to modulate fat desaturation. We also find neuronal hsf-1 is not only sufficient but also partially necessary to control the fat remodelling response and for survival at warm temperatures. This is the first study to show that a thermostat-based mechanism can cell non-autonomously coordinate membrane saturation and composition across tissues in a multicellular animal.","lang":"eng"}],"_id":"13069","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2021","publisher":"Zenodo","department":[{"_id":"MaDe"}],"ddc":["570"],"status":"public","title":"Neuronal HSF-1 coordinates the propagation of fat desaturation across tissues to enable adaptation to high temperatures in C. elegans","related_material":{"record":[{"relation":"used_in_publication","status":"public","id":"10322"}]},"author":[{"full_name":"Chauve, Laetitia","first_name":"Laetitia","last_name":"Chauve"},{"full_name":"Hodge, Francesca","first_name":"Francesca","last_name":"Hodge"},{"full_name":"Murdoch, Sharlene","first_name":"Sharlene","last_name":"Murdoch"},{"full_name":"Masoudzadeh, Fatemah","last_name":"Masoudzadeh","first_name":"Fatemah"},{"full_name":"Mann, Harry-Jack","first_name":"Harry-Jack","last_name":"Mann"},{"last_name":"Lopez-Clavijo","first_name":"Andrea","full_name":"Lopez-Clavijo, Andrea"},{"full_name":"Okkenhaug, Hanneke","first_name":"Hanneke","last_name":"Okkenhaug"},{"full_name":"West, Greg","first_name":"Greg","last_name":"West"},{"last_name":"Sousa","first_name":"Bebiana C.","full_name":"Sousa, Bebiana C."},{"last_name":"Segonds-Pichon","first_name":"Anne","full_name":"Segonds-Pichon, Anne"},{"first_name":"Cheryl","last_name":"Li","full_name":"Li, Cheryl"},{"last_name":"Wingett","first_name":"Steven","full_name":"Wingett, Steven"},{"first_name":"Hermine","last_name":"Kienberger","full_name":"Kienberger, Hermine"},{"full_name":"Kleigrewe, Karin","last_name":"Kleigrewe","first_name":"Karin"},{"full_name":"de Bono, Mario","last_name":"de Bono","first_name":"Mario","orcid":"0000-0001-8347-0443","id":"4E3FF80E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Wakelam, Michael","last_name":"Wakelam","first_name":"Michael"},{"full_name":"Casanueva, Olivia","last_name":"Casanueva","first_name":"Olivia"}],"oa_version":"Published Version","date_created":"2023-05-23T16:40:56Z","date_updated":"2023-08-14T11:53:26Z"},{"publication_identifier":{"eisbn":["978-3-662-64331-0"],"issn":["0302-9743"],"isbn":["9-783-6626-4330-3"],"eissn":["1611-3349"]},"month":"10","external_id":{"isi":["000712016200001"]},"oa":1,"main_file_link":[{"url":"https://eprint.iacr.org/2019/1128","open_access":"1"}],"isi":1,"quality_controlled":"1","doi":"10.1007/978-3-662-64331-0_1","conference":{"end_date":"2021-03-05","start_date":"2021-03-01","location":"Virtual","name":"FC: Financial Cryptography"},"language":[{"iso":"eng"}],"year":"2021","acknowledgement":"We would like express our gratitude to Georgia Avarikioti, Daniel Perez and Dominik Harz for helpful comments and feedback on earlier versions of this manuscript.

While by design, blockchains provide no means to securely communicate with external systems, numerous attempts towards trustless cross-chain communication have been proposed over the years. Today, cross-chain communication (CCC) plays a fundamental role in cryptocurrency exchanges, scalability efforts via sharding, extension of existing systems through sidechains, and bootstrapping of new blockchains. Unfortunately, existing proposals are designed ad-hoc for specific use-cases, making it hard to gain confidence in their correctness and composability. We provide the first systematic exposition of cross-chain communication protocols. We formalize the underlying research problem and show that CCC is impossible without a trusted third party, contrary to common beliefs in the blockchain community. With this result in mind, we develop a framework to design new and evaluate existing CCC protocols, focusing on the inherent trust assumptions thereof, and derive a classification covering the field of cross-chain communication to date. We conclude by discussing open challenges for CCC research and the implications of interoperability on the security and privacy of blockchains."}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10325","title":"SoK: Communication across distributed ledgers","status":"public","oa_version":"Preprint"},{"article_processing_charge":"No","day":"23","scopus_import":"1","date_published":"2021-10-23T00:00:00Z","page":"209-230","citation":{"ista":"Avarikioti Z, Kokoris Kogias E, Wattenhofer R, Zindros D. 2021.

Current proposals, however, require synchrony assumptions to preserve the safety of a channel, leaking to an adversary the exact amount of time needed to control the network for a successful attack. In this paper, we introduce Brick, the first payment channel that remains secure under network asynchrony and concurrently provides correct incentives. The core idea is to incorporate the conflict resolution process within the channel by introducing a rational committee of external parties, called wardens. Hence, if a party wants to close a channel unilaterally, it can only get the committee’s approval for the last valid state. Additionally, Brick provides sub-second latency because it does not employ heavy-weight consensus. Instead, Brick uses consistent broadcast to announce updates and close the channel, a light-weight abstraction that is powerful enough to preserve safety and liveness to any rational parties. We formally define and prove for Brick the properties a payment channel construction should fulfill. We also design incentives for Brick such that honest and rational behavior aligns. Finally, we provide a reference implementation of the smart contracts in Solidity."}],"alternative_title":["LNCS"],"type":"conference","oa_version":"Preprint","title":"Brick: Asynchronous incentive-compatible payment channels","status":"public","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10324","publication_identifier":{"isbn":["9-783-6626-4330-3"],"eissn":["1611-3349"],"eisbn":["978-3-662-64331-0"],"issn":["0302-9743"]},"month":"10","language":[{"iso":"eng"}],"doi":"10.1007/978-3-662-64331-0_11","conference":{"start_date":"2021-03-01","location":"Virtual","end_date":"2021-03-05","name":"FC: Financial Cryptography"},"isi":1,"quality_controlled":"1","main_file_link":[{"url":"https://arxiv.org/abs/1905.11360","open_access":"1"}],"oa":1,"external_id":{"isi":["000712016200011"],"arxiv":["1905.11360"]},"volume":"12675 ","date_created":"2021-11-21T23:01:29Z","date_updated":"2023-08-14T12:59:58Z","author":[{"first_name":"Zeta","last_name":"Avarikioti","full_name":"Avarikioti, Zeta"},{"id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30","first_name":"Eleftherios","last_name":"Kokoris Kogias","full_name":"Kokoris Kogias, Eleftherios"},{"full_name":"Wattenhofer, Roger","last_name":"Wattenhofer","first_name":"Roger"},{"last_name":"Zindros","first_name":"Dionysis","full_name":"Zindros, Dionysis"}],"publisher":"Springer Nature","department":[{"_id":"ElKo"}],"publication_status":"published","year":"2021","acknowledgement":"We would like to thank Kaoutar Elkhiyaoui for her valuable feedback as well as Jakub Sliwinski for his impactful contribution to this work."},{"publication_identifier":{"issn":["1741-0126"],"eissn":["1741-0134"]},"month":"11","quality_controlled":"1","isi":1,"oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/protein/gzab025"}],"external_id":{"isi":["000746596900001"],"pmid":["34725710"]},"language":[{"iso":"eng"}],"doi":"10.1093/protein/gzab025","article_number":"gzab025","department":[{"_id":"CaGu"}],"publisher":"Oxford University Press","publication_status":"published","pmid":1,"acknowledgement":"This work was supported by funds from the Wyss Institute for Biologically Inspired Engineering and the Boston Biomedical Innovation Center (Pilot Award 112475; Drive Award U54HL119145).

We constructed a fusion protein that stimulates red blood cell production and neuroprotection without triggering platelet production, a marker for thrombosis. The protein consists of an anti-glycophorin A nanobody and an erythropoietin mutant (L108A). The mutation reduces activation of erythropoietin receptor homodimers that induce erythropoiesis and thrombosis, but maintains the tissue-protective signaling. The binding of the nanobody element to glycophorin A rescues homodimeric erythropoietin receptor activation on red blood cell precursors. In a cell proliferation assay, the fusion protein is active at 10−14 M, allowing an estimate of the number of receptor–ligand complexes needed for signaling. This fusion protein stimulates erythroid cell proliferation in vitro and in mice, and shows neuroprotective activity in vitro.

Many studies have explored system-specific molecular and cellular regulatory mechanisms, as well as self-organizing rules underlying branching morphogenesis. However, in addition to local cues, branched tissue growth can also be influenced by global guidance. Here, we develop a theoretical framework for a stochastic self-organized branching process in the presence of external cues. Combining analytical theory with numerical simulations, we predict differential signatures of global vs. local regulatory mechanisms on the branching pattern, such as angle distributions, domain size, and space-filling efficiency. We find that branch alignment follows a generic scaling law determined by the strength of global guidance, while local interactions influence the tissue density but not its overall territory. Finally, using zebrafish innervation as a model system, we test these key features of the model experimentally. Our work thus provides quantitative predictions to disentangle the role of different types of cues in shaping branched structures across scales."}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10402","ddc":["573"],"status":"public","title":"Theory of branching morphogenesis by local interactions and global guidance","intvolume":" 12","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"10529","checksum":"63c56ec75314a71e63e7dd2920b3c5b5","success":1,"date_created":"2021-12-10T08:54:09Z","date_updated":"2021-12-10T08:54:09Z","access_level":"open_access","file_name":"2021_NatComm_Ucar.pdf","file_size":2303405,"content_type":"application/pdf","creator":"cchlebak"}]},{"year":"2021","publication_status":"published","publisher":"Springer Nature","department":[{"_id":"KrPi"}],"author":[{"id":"B9CD0494-D033-11E9-B219-A439E6697425","last_name":"Chakraborty","first_name":"Suvradip","full_name":"Chakraborty, Suvradip"},{"first_name":"Stefan","last_name":"Dziembowski","full_name":"Dziembowski, Stefan"},{"full_name":"Gałązka, Małgorzata","first_name":"Małgorzata","last_name":"Gałązka"},{"full_name":"Lizurej, Tomasz","last_name":"Lizurej","first_name":"Tomasz"},{"last_name":"Pietrzak","first_name":"Krzysztof Z","orcid":"0000-0002-9139-1654","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","full_name":"Pietrzak, Krzysztof Z"},{"full_name":"Yeo, Michelle X","last_name":"Yeo","first_name":"Michelle X","id":"2D82B818-F248-11E8-B48F-1D18A9856A87"}],"date_updated":"2023-08-14T13:07:46Z","date_created":"2021-12-05T23:01:42Z","volume":13043,"ec_funded":1,"external_id":{"isi":["000728364000014"]},"oa":1,"main_file_link":[{"url":"https://eprint.iacr.org/2021/1224","open_access":"1"}],"quality_controlled":"1","isi":1,"project":[{"_id":"258AA5B2-B435-11E9-9278-68D0E5697425","grant_number":"682815","name":"Teaching Old Crypto New Tricks","call_identifier":"H2020"}],"conference":{"name":"TCC: Theory of Cryptography Conference","end_date":"2021-11-11","start_date":"2021-11-08","location":"Raleigh, NC, United States"},"doi":"10.1007/978-3-030-90453-1_14","language":[{"iso":"eng"}],"month":"11","publication_identifier":{"issn":["0302-9743"],"eissn":["1611-3349"],"isbn":["9-783-0309-0452-4"]},"_id":"10407","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Trojan-resilience without cryptography","status":"public","intvolume":" 13043","oa_version":"Preprint","type":"conference","alternative_title":["LNCS"],"abstract":[{"text":"Digital hardware Trojans are integrated circuits whose implementation differ from the specification in an arbitrary and malicious way. For example, the circuit can differ from its specified input/output behavior after some fixed number of queries (known as “time bombs”) or on some particular input (known as “cheat codes”). To detect such Trojans, countermeasures using multiparty computation (MPC) or verifiable computation (VC) have been proposed. On a high level, to realize a circuit with specification F one has more sophisticated circuits F⋄ manufactured (where F⋄ specifies a MPC or VC of F ), and then embeds these F⋄ ’s into a master circuit which must be trusted but is relatively simple compared to F . Those solutions impose a significant overhead as F⋄ is much more complex than F , also the master circuits are not exactly trivial. In this work, we show that in restricted settings, where F has no evolving state and is queried on independent inputs, we can achieve a relaxed security notion using very simple constructions. In particular, we do not change the specification of the circuit at all (i.e., F=F⋄ ). Moreover the master circuit basically just queries a subset of its manufactured circuits and checks if they’re all the same. The security we achieve guarantees that, if the manufactured circuits are initially tested on up to T inputs, the master circuit will catch Trojans that try to deviate on significantly more than a 1/T fraction of the inputs. This bound is optimal for the type of construction considered, and we provably achieve it using a construction where 12 instantiations of F need to be embedded into the master. We also discuss an extremely simple construction with just 2 instantiations for which we conjecture that it already achieves the optimal bound.","lang":"eng"}],"citation":{"short":"S. Chakraborty, S.

Yet how these changes influence the neuronal computations necessary for normal brain function are not well understood. To identify cellular mechanisms underlying the maturation of synaptic integration in interneurons, we combined patch-clamp recordings of excitatory inputs in mouse cerebellar stellate cells (SCs), three-dimensional reconstruction of SC morphology with excitatory synapse location, and biophysical modeling. We found that postnatal maturation of postsynaptic strength was homogeneously reduced along the somatodendritic axis, but dendritic integration was always sublinear. However, dendritic branching increased without changes in synapse density, leading to a substantial gain in distal inputs. Thus, changes in synapse distribution, rather than dendrite cable properties, are the dominant mechanism underlying the maturation of neuronal computation. These mechanisms favor the emergence of a spatially compartmentalized two-stage integration model promoting location-dependent integration within dendritic subunits.","lang":"eng"}],"type":"journal_article","language":[{"iso":"eng"}],"doi":"10.7554/eLife.65954","quality_controlled":"1","isi":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"external_id":{"isi":["000715789500001"]},"month":"11","publication_identifier":{"eissn":["2050-084X"]},"date_created":"2021-12-05T23:01:40Z","date_updated":"2023-08-14T13:12:07Z","volume":10,"author":[{"full_name":"Biane, Celia","last_name":"Biane","first_name":"Celia"},{"full_name":"Rückerl, Florian","first_name":"Florian","last_name":"Rückerl"},{"first_name":"Therese","last_name":"Abrahamsson","full_name":"Abrahamsson, Therese"},{"first_name":"Cécile","last_name":"Saint-Cloment","full_name":"Saint-Cloment, Cécile"},{"last_name":"Mariani","first_name":"Jean","full_name":"Mariani, Jean"},{"full_name":"Shigemoto, Ryuichi","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8761-9444","first_name":"Ryuichi","last_name":"Shigemoto"},{"full_name":"Digregorio, David A.","last_name":"Digregorio","first_name":"David A."},{"first_name":"Rachel M.","last_name":"Sherrard","full_name":"Sherrard, Rachel M."},{"full_name":"Cathala, Laurence","first_name":"Laurence","last_name":"Cathala"}],"publication_status":"published","publisher":"eLife Sciences Publications","department":[{"_id":"RySh"}],"acknowledgement":"This study was supported by the Centre National de la Recherche Scientifique and the Agence Nationale de la Recherche (ANR-13-BSV4-00166, to LC and DAD).

In this work, we propose a two-terminal cold-atom simulator to study that interaction. The proposed quantum simulator consists of strongly interacting atoms that occupy two temperature reservoirs connected by a one-dimensional link. First, we argue that the dynamics in the link can be described using an inhomogeneous Heisenberg spin chain whose couplings are defined by the local temperature. Second, we show the existence of a spin current in a system with a temperature difference by studying the dynamics that follows the spin-flip of an atom in the link. A temperature gradient accelerates the impurity in one direction more than in the other, leading to an overall spin current similar to the spin Seebeck effect.","lang":"eng"}],"type":"journal_article","doi":"10.1038/s42005-021-00753-7","language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["10.1038/s42005-021-00753-7"],"arxiv":["2101.02020"]},"oa":1,"project":[{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"quality_controlled":"1","publication_identifier":{"eissn":["23993650"]},"month":"11","author":[{"full_name":"Barfknecht, Rafael E.","first_name":"Rafael E.","last_name":"Barfknecht"},{"full_name":"Foerster, Angela","first_name":"Angela","last_name":"Foerster"},{"last_name":"Zinner","first_name":"Nikolaj T.","full_name":"Zinner, Nikolaj T."},{"last_name":"Volosniev","first_name":"Artem","orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","full_name":"Volosniev, Artem"}],"volume":4,"date_updated":"2023-08-14T13:04:34Z","date_created":"2021-12-05T23:01:39Z","acknowledgement":"The authors acknowledge support from the European QuantERA ERA-NET Cofund in Quantum Technologies (Project QTFLAG Grant Agreement No. 731473) (R.E.B), CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico) Brazil (A.F.), the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 754411 (A.G.V.), the Independent Research Fund Denmark, the Carlsberg Foundation, and Aarhus University Research Foundation under the Jens Christian Skou fellowship program (N.T.Z).","year":"2021","department":[{"_id":"MiLe"}],"publisher":"Springer Nature","publication_status":"published","ec_funded":1,"file_date_updated":"2021-12-06T14:53:41Z","article_number":"252"},{"month":"11","publication_identifier":{"issn":["0167-7055"],"eissn":["1467-8659"]},"isi":1,"quality_controlled":"1","project":[{"_id":"25F42A32-B435-11E9-9278-68D0E5697425","grant_number":"Z211","call_identifier":"FWF","name":"The Wittgenstein Prize"}],"main_file_link":[{"url":"https://arxiv.org/abs/2110.07667","open_access":"1"}],"external_id":{"isi":["000722952000024"],"arxiv":["2110.07667"]},"oa":1,"language":[{"iso":"eng"}],"doi":"10.1111/cgf.14418","publication_status":"published","publisher":"Wiley","department":[{"_id":"ToHe"}],"year":"2021","acknowledgement":"We thank Robert Geirhos and Roland Zimmermann for their participation in the case study and valuable feedback, Chris Olah and Nick Cammarata for valuable discussions in the early phase of the project, as well as the Distill Slack workspace as a platform for discussions.

Morphogenesis involves an interplay between several factors, ranging from the gene regulatory networks determining cell fate and differentiation to the mechanical processes underlying cell and tissue shape changes. Thus, the study of morphogenesis has historically been based on multidisciplinary approaches at the interface of biology with physics and mathematics. Recent technological advances have further improved our ability to study morphogenesis by bridging the gap between the genetic and biophysical factors through the development of new tools for visualizing, analyzing, and perturbing these factors and their biochemical intermediaries. Here, we review how a combination of genetic, microscopic, biophysical, and biochemical approaches has aided our attempts to understand morphogenesis and discuss potential approaches that may be beneficial to such an inquiry in the future."}],"type":"journal_article","oa_version":"None","title":"Dissecting organismal morphogenesis by bridging genetics and biophysics","status":"public","intvolume":" 55","_id":"10406","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","month":"08","publication_identifier":{"eissn":["1545-2948"],"issn":["0066-4197"]},"language":[{"iso":"eng"}],"doi":"10.1146/annurev-genet-071819-103748","isi":1,"quality_controlled":"1","project":[{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"external_id":{"pmid":["34460295"],"isi":["000747220900010"]},"ec_funded":1,"date_updated":"2023-08-14T13:05:13Z","date_created":"2021-12-05T23:01:41Z","volume":55,"author":[{"full_name":"Mishra, Nikhil","id":"C4D70E82-1081-11EA-B3ED-9A4C3DDC885E","orcid":"0000-0002-6425-5788","first_name":"Nikhil","last_name":"Mishra"},{"first_name":"Carl-Philipp J","last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0912-4566","full_name":"Heisenberg, Carl-Philipp J"}],"publication_status":"published","department":[{"_id":"CaHe"}],"publisher":"Annual Reviews","acknowledgement":"The authors would like to thank Feyza Nur Arslan, Suyash Naik, Diana Pinheiro, Alexandra Schauer, and Shayan Shamipour for their comments on the draft.

Applications include multicast encryption protocols like LKH (Logical Key Hierarchies) or group messaging like the current IETF proposal TreeKEM. A key tree is a (typically balanced) binary tree, where each node is identified with a key: leaf nodes hold users’ secret keys while the root is the shared group key. For a group of size N, each user just holds log(N) keys (the keys on the path from its leaf to the root) and its entire key material can be rotated by broadcasting 2log(N) ciphertexts (encrypting each fresh key on the path under the keys of its parents). In this work we consider the natural setting where we have many groups with partially overlapping sets of users, and ask if we can find solutions where the cost of rotating a key is better than in the trivial one where we have a separate key tree for each group. We show that in an asymptotic setting (where the number m of groups is fixed while the number N of users grows) there exist more general key graphs whose cost converges to the cost of a single group, thus saving a factor linear in the number of groups over the trivial solution. As our asymptotic “solution” converges very slowly and performs poorly on concrete examples, we propose an algorithm that uses a natural heuristic to compute a key graph for any given group structure. Our algorithm combines two greedy algorithms, and is thus very efficient: it first converts the group structure into a “lattice graph”, which is then turned into a key graph by repeatedly applying the algorithm for constructing a Huffman code. To better understand how far our proposal is from an optimal solution, we prove lower bounds on the update cost of continuous group-key agreement and multicast encryption in a symbolic model admitting (asymmetric) encryption, pseudorandom generators, and secret sharing as building blocks."}],"title":"Grafting key trees: Efficient key management for overlapping groups","status":"public","intvolume":" 13044","_id":"10408","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","oa_version":"Preprint","scopus_import":"1","day":"04","article_processing_charge":"No","page":"222-253","publication":"19th International Conference","citation":{"ama":"Alwen JF, Auerbach B, Baig MA, et al.

Superconductivity is strongly enhanced when the inner and outer Fermi surfaces are close to each other. The most prevalent state has chiral p-wave symmetry, but d-wave and extended s-wave pairing are also possible. We discuss these results in the context of rhombohedral trilayer graphene, where superconductivity was recently discovered in regimes where the normal state has an annular Fermi surface. Using realistic parameters, our mechanism can account for the order of magnitude of Tc, as well as its trends as a function of electron density and perpendicular displacement field. Moreover, it naturally explains some of the outstanding puzzles in this material, that include the weak temperature dependence of the resistivity above Tc, and the proximity of spin singlet superconductivity to the ferromagnetic phase."}],"issue":"24","_id":"10527","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","title":"Unconventional superconductivity in systems with annular Fermi surfaces: Application to rhombohedral trilayer graphene","status":"public","intvolume":" 127","oa_version":"Preprint","month":"12","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"external_id":{"arxiv":["2109.00011"],"isi":["000923819400004"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2109.00011"}],"oa":1,"quality_controlled":"1","isi":1,"project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships"}],"doi":"10.1103/physrevlett.127.247001","language":[{"iso":"eng"}],"article_number":"247001","ec_funded":1,"year":"2021","acknowledgement":"We thank Yang-Zhi Chou, Andrey Chubukov, Johannes Hofmann, Steve Kivelson, Sri Raghu, and Sankar das Sarma, Jay Sau, Fengcheng Wu, and Andrea Young for many stimulating discussions and for their comments on the manuscript.

Recently, fullerene derivatives functionalized with ethylene glycol (EG) side chains have been showing important properties such as enhanced dielectric constants, facile doping and enhanced self-assembly capabilities. Here, we have prepared field-effect transistors using a series of these fullerene derivatives equipped with EG side chains of different lengths. Transport data show the beneficial effect of increasing the EG side chain. In order to understand the material properties, full structural determination of these fullerene derivatives has been achieved by coupling the X-ray data with molecular dynamics (MD) simulations. The increase in transport properties is paired with the formation of extended layered structures, efficient molecular packing and an increase in the crystallite alignment. The layer-like structure is composed of conducting layers, containing of closely packed C60 balls approaching the inter-distance of 1 nm, that are separated by well-defined EG layers, where the EG chains are rather splayed with the chain direction almost perpendicular to the layer normal. Such a layered structure appears highly ordered and highly aligned with the C60 planes oriented parallel to the substrate in the thin film configuration. The order inside the thin film increases with the EG chain length, allowing the systems to achieve mobilities as high as 0.053 cm2 V−1 s−1. Our work elucidates the structure of these interesting semiconducting organic molecules and shows that the synergistic use of X-ray structural analysis and MD simulations is a powerful tool to identify the structure of thin organic films for optoelectronic applications."}],"type":"journal_article","language":[{"iso":"eng"}],"doi":"10.1039/d1tc02753k","quality_controlled":"1","isi":1,"external_id":{"isi":["000688135700001"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"publication_identifier":{"issn":["2050-7534"],"eissn":["2050-7526"]},"month":"12","volume":9,"date_created":"2021-12-12T23:01:27Z","date_updated":"2023-08-17T06:18:44Z","author":[{"full_name":"Dong, Jingjin","first_name":"Jingjin","last_name":"Dong"},{"last_name":"Sami","first_name":"Selim","full_name":"Sami, Selim"},{"first_name":"Daniel","last_name":"Balazs","id":"302BADF6-85FC-11EA-9E3B-B9493DDC885E","orcid":"0000-0001-7597-043X","full_name":"Balazs, Daniel"},{"full_name":"Alessandri, Riccardo","last_name":"Alessandri","first_name":"Riccardo"},{"full_name":"Jahani, Fatimeh","last_name":"Jahani","first_name":"Fatimeh"},{"first_name":"Li","last_name":"Qiu","full_name":"Qiu, Li"},{"full_name":"Marrink, Siewert J.","last_name":"Marrink","first_name":"Siewert J."},{"first_name":"Remco W.A.","last_name":"Havenith","full_name":"Havenith, Remco W.A."},{"first_name":"Jan C.","last_name":"Hummelen","full_name":"Hummelen, Jan C."},{"first_name":"Maria A.","last_name":"Loi","full_name":"Loi, Maria A."},{"first_name":"Giuseppe","last_name":"Portale","full_name":"Portale, Giuseppe"}],"publisher":"Royal Society of Chemistry","department":[{"_id":"MaIb"}],"publication_status":"published","year":"2021","acknowledgement":"J.

This RNA-directed DNA methylation (RdDM) pathway preferentially targets euchromatic transposable elements. However, RdDM is thought to be recruited by methylation of histone H3 at lysine 9 (H3K9me), a hallmark of heterochromatin. How RdDM is targeted to euchromatin despite an affinity for H3K9me is unclear. Here we show that loss of histone H1 enhances heterochromatic RdDM, preferentially at nucleosome linker DNA. Surprisingly, this does not require SHH1, the RdDM component that binds H3K9me. Furthermore, H3K9me is dispensable for RdDM, as is CG DNA methylation. Instead, we find that non-CG methylation is specifically associated with small RNA biogenesis, and without H1 small RNA production quantitatively expands to non-CG methylated loci. Our results demonstrate that H1 enforces the separation of euchromatic and heterochromatic DNA methylation pathways by excluding the small RNA-generating branch of RdDM from non-CG methylated heterochromatin.","lang":"eng"}],"_id":"10533","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","intvolume":" 10","ddc":["570"],"status":"public","title":"Histone H1 prevents non-CG methylation-mediated small RNA biogenesis in Arabidopsis heterochromatin","oa_version":"Published Version","file":[{"date_created":"2022-05-16T10:42:22Z","date_updated":"2022-05-16T10:42:22Z","success":1,"checksum":"22ed4c55fb550f6da02ae55c359be651","file_id":"11384","relation":"main_file","creator":"dernst","content_type":"application/pdf","file_size":2715200,"file_name":"2021_eLife_Choi.pdf","access_level":"open_access"}]},{"_id":"10536","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","ddc":["610"],"status":"public","title":"TGFβ signaling in myeloid cells promotes lung and liver metastasis through different mechanisms","intvolume":" 11","file":[{"checksum":"56cbac80e6891ce750511a30161b7792","success":1,"date_created":"2021-12-13T13:32:37Z","date_updated":"2021-12-13T13:32:37Z","relation":"main_file","file_id":"10539","file_size":9245199,"content_type":"application/pdf","creator":"alisjak","access_level":"open_access","file_name":"2021_Frontiers_Stefanescu.pdf"}],"oa_version":"Published Version","type":"journal_article","abstract":[{"lang":"eng","text":"TGFβ overexpression is commonly detected in cancer patients and correlates with poor prognosis and metastasis. Cancer progression is often associated with an enhanced recruitment of myeloid-derived cells to the tumor microenvironment. Here we show that functional TGFβ-signaling in myeloid cells is required for metastasis to the lungs and the liver. Myeloid-specific deletion of Tgfbr2 resulted in reduced spontaneous lung metastasis, which was associated with a reduction of proinflammatory cytokines in the metastatic microenvironment. Notably, CD8+ T cell depletion in myeloid-specific Tgfbr2-deficient mice rescued lung metastasis. Myeloid-specific Tgfbr2-deficiency resulted in reduced liver metastasis with an almost complete absence of myeloid cells within metastatic foci. On contrary, an accumulation of Tgfβ-responsive myeloid cells was associated with an increased recruitment of monocytes and granulocytes and higher proinflammatory cytokine levels in control mice. Monocytic cells isolated from metastatic livers of Tgfbr2-deficient mice showed increased polarization towards the M1 phenotype, Tnfα and Il-1β expression, reduced levels of M2 markers and reduced production of chemokines responsible for myeloid-cell recruitment. No significant differences in Tgfβ levels were observed at metastatic sites of any model. These data demonstrate that Tgfβ signaling in monocytic myeloid cells suppresses CD8+ T cell activity during lung metastasis, while these cells actively contribute to tumor growth during liver metastasis. Thus, myeloid cells modulate metastasis through different mechanisms in a tissue-specific manner."}],"publication":"Frontiers in Oncology","citation":{"chicago":"Stefanescu, Cristina, Merel Van Gogh, Marko Roblek, Mathias Heikenwalder, and Lubor Borsig. “TGFβ Signaling in Myeloid Cells Promotes Lung and Liver Metastasis through Different Mechanisms.” Frontiers in Oncology.

Until now, many theoretical works studied the performance of quantum algorithms for models with a unique ground state. However, when the classical problem is in a so-called clustering phase, the ground state manifold is highly degenerate. As an example, we consider a 3-XORSAT model defined on simple hypergraphs. The degeneracy of classical ground state manifold translates into the emergence of an extensive number of Z2 symmetries, which remain intact even in the presence of a quantum transverse magnetic field. We establish a general duality approach that restricts the quantum problem to a given sector of conserved Z2 charges and use it to study how the outcome of the quantum adiabatic algorithm depends on the hypergraph geometry. We show that the tree hypergraph which corresponds to a classically solvable instance of the 3-XORSAT problem features a constant gap, whereas the closed hypergraph encounters a second-order phase transition with a gap vanishing as a power-law in the problem size. The duality developed in this work provides a practical tool for studies of quantum models with classically degenerate energy manifold and reveals potential connections between glasses and gauge theories.","lang":"eng"}],"type":"journal_article","date_published":"2021-12-14T00:00:00Z","article_type":"original","citation":{"ama":"Medina Ramos RA, Serbyn M.

In contrast to genetic adaptation that spans multiple generations as an evolutionary process, phenotypic plasticity allows acclimation within the life-time of an organism. Genetic adaptation and phenotypic plasticity are usually studied in isolation, however, only by including their interactive impact, we can understand acclimation and adaptation in nature. We aimed to explore the contribution of adaptation and plasticity in coping with an abiotic (salinity) and a biotic (Vibrio bacteria) stressor using six different populations of the broad-nosed pipefish Syngnathus typhle that originated from either high [14–17 Practical Salinity Unit (PSU)] or low (7–11 PSU) saline environments along the German coastline of the Baltic Sea. We exposed wild caught animals, to either high (15 PSU) or low (7 PSU) salinity, representing native and novel salinity conditions and allowed animals to mate. After male pregnancy, offspring was split and each half was exposed to one of the two salinities and infected with Vibrio alginolyticus bacteria that were evolved at either of the two salinities in a fully reciprocal design. We investigated life-history traits of fathers and expression of 47 target genes in mothers and offspring. Pregnant males originating from high salinity exposed to low salinity were highly susceptible to opportunistic fungi infections resulting in decreased offspring size and number. In contrast, no signs of fungal infection were identified in fathers originating from low saline conditions suggesting that genetic adaptation has the potential to overcome the challenges encountered at low salinity. Offspring from parents with low saline origin survived better at low salinity suggesting genetic adaptation to low salinity. In addition, gene expression analyses of juveniles indicated patterns of local adaptation, trans-generational plasticity and developmental plasticity. In conclusion, our study suggests that pipefish are locally adapted to the low salinity in their environment, however, they are retaining phenotypic plasticity, which allows them to also cope with ancestral salinity levels and prevailing pathogens.","lang":"eng"}],"type":"journal_article","oa_version":"Published Version","file":[{"success":1,"checksum":"8d6e2b767bb0240a9b5a3a3555be51fd","date_created":"2021-12-20T10:44:20Z","date_updated":"2021-12-20T10:44:20Z","file_id":"10572","relation":"main_file","creator":"alisjak","file_size":3175085,"content_type":"application/pdf","access_level":"open_access","file_name":"2021_Frontiers_Goehlich.pdf"}],"_id":"10568","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","intvolume":" 9","ddc":["597"],"status":"public","title":"Pipefish locally adapted to low salinity in the Baltic Sea retain phenotypic plasticity to cope with ancestral salinity levels","has_accepted_license":"1","article_processing_charge":"No","day":"25","scopus_import":"1","keyword":["ecology","evolution","behavior and systematics","trans-generational plasticity","genetic adaptation","local adaptation","phenotypic plasticity","Baltic Sea","climate change","salinity","syngnathids"],"date_published":"2021-03-25T00:00:00Z","citation":{"mla":"Goehlich, Henry, et al. “Pipefish Locally Adapted to Low Salinity in the Baltic Sea Retain Phenotypic Plasticity to Cope with Ancestral Salinity Levels.” Frontiers in Ecology and Evolution, vol. 9, 626442, Frontiers Media, 2021, doi:10.3389/fevo.2021.626442.","short":"H.

The demonstrated system consists of a floating solar receiver having a vertically cross-linked microchannel for wicking up saline water. The in situ polymerized Fe2O3@PPy interfacial layer promotes diffuse reflection and its rough black surface allows Omni-directional solar absorption (94%) and facilitates efficient thermal localization at the water/air interface and offers a defect-rich surface to promote heat localization (41.9 °C) and excellent thermal management due to cellulosic content. The self-floating composite foam reveals continuous vapors generation at a rate of 1.52 kg m−2 h−1 under one 1 kW m−2 and profound evaporating efficiency (95%) without heat losses that dissipates in its surroundings. Indeed, long-term evaporation experiments reveal the negligible disparity in continuous evaporation rate (33.84 kg m−2/8.3 h) receiving two sun solar intensity, and ensures the stability of the device under intense seawater conditions synchronized with excellent salt rejection potential. More importantly, Raman spectroscopy investigation validates the orange dye rejection via Fe2O3@PPy solar evaporator. The combined advantages of high efficiency, self-floating capability, multimedia rejection, low cost, and this configuration are promising for producing large-scale solar steam generating systems appropriate for commercial clean water yield due to their scalable fabrication.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10586","intvolume":" 11","ddc":["620"],"title":"Fe2O3 nanoparticles deposited over self-floating facial sponge for facile interfacial seawater solar desalination","status":"public","oa_version":"Published Version","file":[{"creator":"alisjak","content_type":"application/pdf","file_size":4569639,"access_level":"open_access","file_name":"2021_Crystals_Yuzheng.pdf","success":1,"checksum":"668e9d777608ce0a3bc2e305133bd06b","date_updated":"2022-01-03T09:46:53Z","date_created":"2022-01-03T09:46:53Z","file_id":"10591","relation":"main_file"}],"publication_identifier":{"eissn":["2073-4352"]},"month":"12","external_id":{"isi":["000736602200001"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"isi":1,"quality_controlled":"1","doi":"10.3390/cryst11121509","language":[{"iso":"eng"}],"article_number":"1509","file_date_updated":"2022-01-03T09:46:53Z","acknowledgement":"The authors extend their appreciation to King Saud University for funding this work through Researchers Supporting Project number (RSP-2021/387), King Saud University, Riyadh, Saudi Arabia.","year":"2021","department":[{"_id":"KiMo"}],"publisher":"MDPI","publication_status":"published","author":[{"last_name":"Lu","first_name":"Yuzheng","full_name":"Lu, Yuzheng"},{"first_name":"Naila","last_name":"Arshad","full_name":"Arshad, Naila"},{"full_name":"Irshad, Muhammad Sultan","last_name":"Irshad","first_name":"Muhammad Sultan"},{"first_name":"Iftikhar","last_name":"Ahmed","full_name":"Ahmed, Iftikhar"},{"last_name":"Ahmad","first_name":"Shafiq","full_name":"Ahmad, Shafiq"},{"full_name":"Alshahrani, Lina Abdullah","first_name":"Lina Abdullah","last_name":"Alshahrani"},{"full_name":"Yousaf, Muhammad","first_name":"Muhammad","last_name":"Yousaf"},{"first_name":"Abdelaty Edrees","last_name":"Sayed","full_name":"Sayed, Abdelaty Edrees"},{"first_name":"Muhammad","last_name":"Nauman","id":"32c21954-2022-11eb-9d5f-af9f93c24e71","orcid":"0000-0002-2111-4846","full_name":"Nauman, Muhammad"}],"volume":11,"date_created":"2022-01-02T23:01:34Z","date_updated":"2023-08-17T06:31:20Z"},{"author":[{"first_name":"B","last_name":"Szabo","full_name":"Szabo, B"},{"first_name":"R","last_name":"Mangione","full_name":"Mangione, R"},{"full_name":"Rath, M","first_name":"M","last_name":"Rath"},{"full_name":"Pašukonis, A","last_name":"Pašukonis","first_name":"A"},{"full_name":"Reber, SA","last_name":"Reber","first_name":"SA"},{"orcid":"0000-0001-7425-2372","id":"403169A4-080F-11EA-9993-BF3F3DDC885E","last_name":"Oh","first_name":"Jinook","full_name":"Oh, Jinook"},{"full_name":"Ringler, M","last_name":"Ringler","first_name":"M"},{"full_name":"Ringler, E","last_name":"Ringler","first_name":"E"}],"date_created":"2021-12-20T07:54:22Z","date_updated":"2023-08-17T06:26:15Z","volume":224,"acknowledgement":"We are grateful to Véronique Helfer, Walter Hödl, Lisa Schretzmeyer and Julia Wotke, who assisted with fieldwork in French Guiana.

The recognition of cues originating from predators can be innate or learned. Cues of various modalities might be used alone or in multi-modal combinations to detect and distinguish predators but studies investigating multi-modal integration in predator avoidance are scarce. Here, we used wild, naive tadpoles of the Neotropical poison frog Allobates femoralis ( Boulenger, 1884) to test their reaction to cues with two modalities from two different sympatrically occurring potential predators: heterospecific predatory Dendrobates tinctorius tadpoles and dragonfly larvae. We presented A. femoralis tadpoles with olfactory or visual cues, or a combination of the two, and compared their reaction to a water control in a between-individual design. In our trials, A. femoralis tadpoles reacted to multi-modal stimuli (a combination of visual and chemical information) originating from dragonfly larvae with avoidance but showed no reaction to uni-modal cues or cues from heterospecific tadpoles. In addition, visual cues from conspecifics increased swimming activity while cues from predators had no effect on tadpole activity. Our results show that A. femoralis tadpoles can innately recognize some predators and probably need both visual and chemical information to effectively avoid them. This is the first study looking at anti-predator behavior in poison frog tadpoles. We discuss how parental care might influence the expression of predator avoidance responses in tadpoles.","lang":"eng"}],"issue":"24","type":"journal_article","date_published":"2021-12-16T00:00:00Z","publication":"Journal of Experimental Biology","citation":{"short":"B.

Still the assumption of the no-slip condition is preferred in order to avoid boundary terms in the analysis and slipping effects are usually overlooked. Besides the “static slip models”, there are phenomena that are not accurately described by them, e.g. at the moment when the slip changes rapidly, the wall shear stress and the slip can exhibit a sudden overshoot and subsequent relaxation. When these effects become significant, the so-called dynamic slip phenomenon occurs.

Recently, Serrano et al. collected the largest dataset to date with subjective ratings of material appearance attributes, including glossiness, metallicness, sharpness and contrast of reflections. In this work, we make use of their dataset to investigate for the first time the impact of the interactions between illumination, geometry, and eight different material categories in perceived appearance attributes. After an initial analysis, we select for further analysis the four material categories that cover the largest range for all perceptual attributes: fabric, plastic, ceramic, and metal. Using a cumulative link mixed model (CLMM) for robust regression, we discover interactions between these material categories and four representative illuminations and object geometries. We believe that our findings contribute to expanding the knowledge on material appearance perception and can be useful for many applications, such as scene design, where any particular material in a given shape can be aligned with dominant classes of illumination, so that a desired strength of appearance attributes can be achieved."}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10574","intvolume":" 37","status":"public","ddc":["000"],"title":"The effect of geometry and illumination on appearance perception of different material categories","file":[{"checksum":"244cfcac0479ca6e3444c098ab2860a1","success":1,"date_updated":"2021-12-27T13:51:08Z","date_created":"2021-12-27T13:51:08Z","relation":"main_file","file_id":"10578","content_type":"application/pdf","file_size":5741094,"creator":"cchlebak","access_level":"open_access","file_name":"2021_VisComput_Chen.pdf"}],"oa_version":"Published Version","publication_identifier":{"issn":["0178-2789"],"eissn":["1432-2315"]},"month":"12","oa":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000673536600003"]},"isi":1,"quality_controlled":"1","doi":"10.1007/s00371-021-02227-x","language":[{"iso":"eng"}],"file_date_updated":"2021-12-27T13:51:08Z","acknowledgement":"This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie, grant agreement N∘ 765911 (RealVision) and from the European Research Council (ERC), grant agreement N∘ 804226 (PERDY).

Zebrafish semicircular canals form from invaginations in the otic epithelium (buds) that extend and fuse to form the hubs of each canal. We find that conventional actomyosin-driven behaviors are not required. Instead, local secretion of hyaluronan, made by the enzymes uridine 5′-diphosphate dehydrogenase (ugdh) and hyaluronan synthase 3 (has3), drives canal morphogenesis. Charged hyaluronate polymers osmotically swell with water and generate isotropic extracellular pressure to deform the overlying epithelium into buds. The mechanical anisotropy needed to shape buds into tubes is conferred by a polarized distribution of actomyosin and E-cadherin-rich membrane tethers, which we term cytocinches. Most work on tissue morphogenesis ascribes actomyosin contractility as the driving force, while the extracellular matrix shapes tissues through differential stiffness. Our work inverts this expectation. Hyaluronate pressure shaped by anisotropic tissue stiffness may be a widespread mechanism for powering morphological change in organogenesis and tissue engineering.","lang":"eng"}],"quality_controlled":"1","isi":1,"main_file_link":[{"open_access":"1","url":"https://www.biorxiv.org/content/10.1101/2020.09.28.316042"}],"external_id":{"isi":["000735387500002"]},"oa":1,"language":[{"iso":"eng"}],"doi":"10.1016/j.cell.2021.11.025","publication_identifier":{"eissn":["1097-4172"],"issn":["0092-8674"]},"month":"12","publisher":"Elsevier ; Cell Press","department":[{"_id":"EdHa"}],"publication_status":"published","year":"2021","acknowledgement":"We thank Ian Swinburne, Sandy Nandagopal, and Toru Kawanishi for support, discussions, and reagents.

Such games are central in formal methods since they model the interaction between a non-terminating system and its environment. In bidding games the players bid for the right to move the token: in each round, the players simultaneously submit bids, and the higher bidder moves the token and pays the other player. Bidding games are known to have a clean and elegant mathematical structure that relies on the ability of the players to submit arbitrarily small bids. Many applications, however, require a fixed granularity for the bids, which can represent, for example, the monetary value expressed in cents. We study, for the first time, the combination of discrete-bidding and infinite-duration games. Our most important result proves that these games form a large determined subclass of concurrent games, where determinacy is the strong property that there always exists exactly one player who can guarantee winning the game. In particular, we show that, in contrast to non-discrete bidding games, the mechanism with which tied bids are resolved plays an important role in discrete-bidding games. We study several natural tie-breaking mechanisms and show that, while some do not admit determinacy, most natural mechanisms imply determinacy for every pair of initial budgets."}],"type":"journal_article","file":[{"file_size":819878,"content_type":"application/pdf","creator":"alisjak","file_name":"2021_LMCS_AGHAJOHAR.pdf","access_level":"open_access","date_updated":"2022-01-26T08:04:50Z","date_created":"2022-01-26T08:04:50Z","checksum":"b35586a50ed1ca8f44767de116d18d81","success":1,"relation":"main_file","file_id":"10690"}],"oa_version":"Published Version","_id":"10674","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","intvolume":" 17","status":"public","title":"Determinacy in discrete-bidding infinite-duration games","ddc":["510"],"publication_identifier":{"eissn":["1860-5974"]},"month":"02","doi":"10.23638/LMCS-17(1:10)2021","language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"external_id":{"isi":["000658724600010"],"arxiv":["1905.03588"]},"project":[{"_id":"264B3912-B435-11E9-9278-68D0E5697425","grant_number":"M02369","name":"Formal Methods meets Algorithmic Game Theory","call_identifier":"FWF"},{"name":"Rigorous Systems Engineering","call_identifier":"FWF","_id":"25F2ACDE-B435-11E9-9278-68D0E5697425","grant_number":"S11402-N23"},{"name":"The Wittgenstein Prize","call_identifier":"FWF","grant_number":"Z211","_id":"25F42A32-B435-11E9-9278-68D0E5697425"}],"isi":1,"quality_controlled":"1","file_date_updated":"2022-01-26T08:04:50Z","author":[{"full_name":"Aghajohari, Milad","first_name":"Milad","last_name":"Aghajohari"},{"orcid":"0000-0001-5588-8287","id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","last_name":"Avni","first_name":"Guy","full_name":"Avni, Guy"},{"orcid":"0000-0002-2985-7724","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","last_name":"Henzinger","first_name":"Thomas A","full_name":"Henzinger, Thomas A"}],"volume":17,"date_updated":"2023-08-17T06:56:42Z","date_created":"2022-01-25T16:32:13Z","year":"2021","acknowledgement":"This research was supported in part by the Austrian Science Fund (FWF) under grants S11402-N23 (RiSE/SHiNE), Z211-N23 (Wittgenstein Award), and M 2369-N33 (Meitner fellowship).\r\n","department":[{"_id":"ToHe"}],"publisher":"International Federation for Computational Logic","publication_status":"published"},{"ec_funded":1,"date_updated":"2023-08-17T06:34:41Z","date_created":"2022-01-09T23:01:27Z","volume":13091,"author":[{"full_name":"Chakraborty, Suvradip","first_name":"Suvradip","last_name":"Chakraborty","id":"B9CD0494-D033-11E9-B219-A439E6697425"},{"full_name":"Ganesh, Chaya","last_name":"Ganesh","first_name":"Chaya"},{"first_name":"Mahak","last_name":"Pancholi","full_name":"Pancholi, Mahak"},{"first_name":"Pratik","last_name":"Sarkar","full_name":"Sarkar, Pratik"}],"publication_status":"published","department":[{"_id":"KrPi"}],"publisher":"Springer Nature","year":"2021","month":"12","publication_identifier":{"isbn":["978-3-030-92074-6"],"eissn":["1611-3349"],"eisbn":["978-3-030-92075-3"],"issn":["0302-9743"]},"language":[{"iso":"eng"}],"conference":{"end_date":"2021-12-10","location":"Virtual, Singapore","start_date":"2021-12-06","name":"ASIACRYPT: International Conference on Cryptology in Asia"},"doi":"10.1007/978-3-030-92075-3_12","quality_controlled":"1","isi":1,"project":[{"name":"Teaching Old Crypto New Tricks","call_identifier":"H2020","grant_number":"682815","_id":"258AA5B2-B435-11E9-9278-68D0E5697425"}],"main_file_link":[{"url":"https://eprint.iacr.org/2021/1262","open_access":"1"}],"external_id":{"isi":["000927876200012"]},"oa":1,"abstract":[{"lang":"eng","text":"We study Multi-party computation (MPC) in the setting of subversion, where the adversary tampers with the machines of honest parties. Our goal is to construct actively secure MPC protocols where parties are corrupted adaptively by an adversary (as in the standard adaptive security setting), and in addition, honest parties’ machines are compromised.\r\nThe idea of reverse firewalls (RF) was introduced at EUROCRYPT’15 by Mironov and Stephens-Davidowitz as an approach to protecting protocols against corruption of honest parties’ devices. Intuitively, an RF for a party P is an external entity that sits between P and the outside world and whose scope is to sanitize P ’s incoming and outgoing messages in the face of subversion of their computer. Mironov and Stephens-Davidowitz constructed a protocol for passively-secure two-party computation. At CRYPTO’20, Chakraborty, Dziembowski and Nielsen constructed a protocol for secure computation with firewalls that improved on this result, both by extending it to multi-party computation protocol, and considering active security in the presence of static corruptions. In this paper, we initiate the study of RF for MPC in the adaptive setting. We put forward a definition for adaptively secure MPC in the reverse firewall setting, explore relationships among the security notions, and then construct reverse firewalls for MPC in this stronger setting of adaptive security. We also resolve the open question of Chakraborty, Dziembowski and Nielsen by removing the need for a trusted setup in constructing RF for MPC. Towards this end, we construct reverse firewalls for adaptively secure augmented coin tossing and adaptively secure zero-knowledge protocols and obtain a constant round adaptively secure MPC protocol in the reverse firewall setting without setup. Along the way, we propose a new multi-party adaptively secure coin tossing protocol in the plain model, that is of independent interest."}],"alternative_title":["LNCS"],"type":"conference","oa_version":"Preprint","title":"Reverse firewalls for adaptively secure MPC without setup","status":"public","intvolume":" 13091","_id":"10609","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","day":"01","article_processing_charge":"No","scopus_import":"1","date_published":"2021-12-01T00:00:00Z","page":"335-364","publication":"27th International Conference on the Theory and Application of Cryptology and Information Security","citation":{"short":"S.

Depending on the level of cell shape anisotropy or the strength of the polarity domain, one dominates the other and determines the orientation of the spindle. Whether and how such competition is also at work to determine unequal cell division (UCD), producing daughter cells of different size, remains unclear. Here, we show that cell geometry and polarity domains cooperate, rather than compete, in positioning the cleavage plane during UCDs in early ascidian embryos. We found that the UCDs and their orientation at the ascidian third cleavage rely on the spindle tilting in an anisotropic cell shape, and cortical polarity domains exerting different effects on spindle astral microtubules. By systematically varying mitotic cell shape, we could modulate the effect of attractive and repulsive polarity domains and consequently generate predicted daughter cell size asymmetries and position. We therefore propose that the spindle position during UCD is set by the combined activities of cell geometry and polarity domains, where cell geometry modulates the effect of cortical polarity domain(s).","lang":"eng"}],"type":"journal_article","date_published":"2021-12-21T00:00:00Z","article_type":"original","publication":"eLife","citation":{"apa":"Godard, B.

Experimental data suggest that microglial TLR4 mediates the uptake and clearance of α-synuclein also termed synucleinophagy. The accumulation of misfolded α-synuclein throughout the brain is central to Parkinson's disease (PD). The distribution and progression of the pathology is often attributed to the propagation of α-synuclein. Here, we apply a classical α-synuclein propagation model of prodromal PD in wild type and TLR4 deficient mice to study the role of TLR4 in the progression of the disease. Our data suggest that TLR4 deficiency facilitates the α-synuclein seed spreading associated with reduced lysosomal activity of microglia. Three months after seed inoculation, more pronounced proteinase K-resistant α-synuclein inclusion pathology is observed in mice with TLR4 deficiency. The facilitated propagation of α-synuclein is associated with early loss of dopamine transporter (DAT) signal in the striatum and loss of dopaminergic neurons in substantia nigra pars compacta of TLR4 deficient mice. These new results support TLR4 signaling as a putative target for disease modification to slow the progression of PD and related disorders.","lang":"eng"}],"type":"journal_article","file":[{"file_name":"2021_Parkinsonism_Venezia.pdf","access_level":"open_access","creator":"alisjak","content_type":"application/pdf","file_size":6848513,"file_id":"10612","relation":"main_file","date_created":"2022-01-10T13:41:40Z","date_updated":"2022-01-10T13:41:40Z","success":1,"checksum":"360681585acb51e80d17c6b213c56b55"}],"oa_version":"Published Version","title":"Toll-like receptor 4 deficiency facilitates α-synuclein propagation and neurodegeneration in a mouse model of prodromal Parkinson's disease","ddc":["610"],"status":"public","intvolume":" 91","_id":"10607","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","day":"01","has_accepted_license":"1","article_processing_charge":"No","scopus_import":"1","date_published":"2021-10-01T00:00:00Z","article_type":"original","page":"59-65","publication":"Parkinsonism & Related Disorders","citation":{"chicago":"Venezia, Serena, Walter Kaufmann, Gregor K.

In contrast, we find that topological Kondo insulators (TKIs) can support surface states with an arbitrarily large Fermi surface (FS) when the chemical potential is pinned to the Dirac point. We illustrate that these FSs give rise to finite-frequency QOs, which can become comparable to the extremal area of the unhybridized bulk bands. We show that this occurs when the crystal symmetry is lowered from cubic to tetragonal in a minimal two-orbital model. We label such surface modes as 'shadow surface states'. Moreover, we show that the sufficient next-nearest neighbor out-of-plane hybridization leading to shadow surface states can be self-consistently stabilized for tetragonal TKIs. Consequently, shadow surface states provide an important example of high-frequency QOs beyond the context of cubic TKIs."}],"type":"journal_article","file":[{"date_updated":"2022-01-17T10:01:58Z","date_created":"2022-01-17T10:01:58Z","checksum":"0c3cb6816242fa8afd1cc87a5fe77821","success":1,"relation":"main_file","file_id":"10632","content_type":"application/pdf","file_size":2533102,"creator":"cchlebak","file_name":"2021_NewJourPhys_Ghazaryan.pdf","access_level":"open_access"}],"oa_version":"Published Version","_id":"10628","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","intvolume":" 23","status":"public","ddc":["530"],"title":"Shadow surface states in topological Kondo insulators"},{"article_type":"original","citation":{"apa":"Cherepanov, I., Bighin, G., Schouder, C.

We construct a simple quantum-mechanical model, based on a linear rotor coupled to a single-mode bosonic bath, to determine the rotational energy structure in its entirety.

While adversarial training appears to enhance the robustness and safety of a deep model deployed in open-world decision-critical applications, counterintuitively, it induces undesired behaviors in robot learning settings. In this paper, we show theoretically and experimentally that neural controllers obtained via adversarial training are subjected to three types of defects, namely transient, systematic, and conditional errors. We first generalize adversarial training to a safety-domain optimization scheme allowing for more generic specifications. We then prove that such a learning process tends to cause certain error profiles. We support our theoretical results by a thorough experimental safety analysis in a robot-learning task.

Intuitively, the efficiency of this process depends on how many electrons (charge carriers) can move and how easily they do so, how much energy those moving electrons transport, and how easily the temperature gradient is maintained. In terms of material properties, an excellent thermoelectric material requires a high electrical conductivity σ, a high Seebeck coefficient S (a measure of the induced thermoelectric voltage as a function of temperature gradient), and a low thermal conductivity κ. The challenge is that these three properties are strongly interrelated in a conflicting manner (1). On page 722 of this issue, Roychowdhury et al.

Bi2Se3 is an obvious possible Te-free alternative to Bi2Te3 for ambient temperature thermoelectric applications, but its performance is still low for practical applications, and additional efforts toward finding proper dopants are required. Here, we report a scalable method to produce Bi2Se3 nanosheets at low synthesis temperatures. We studied the influence of different dopants on the thermoelectric properties of this material. Among the elements tested, we demonstrated that Sn doping resulted in the best performance. Sn incorporation resulted in a significant improvement to the Bi2Se3 Seebeck coefficient and a reduction in the thermal conductivity in the direction of the hot-press axis, resulting in an overall 60% improvement in the thermoelectric figure of merit of Bi2Se3.","lang":"eng"}],"type":"journal_article","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"10859","date_created":"2022-03-18T09:53:15Z","date_updated":"2022-03-18T09:53:15Z","checksum":"f28a8b5cf80f5605828359bb398463b0","success":1,"file_name":"2021_Nanomaterials_Li.pdf","access_level":"open_access","content_type":"application/pdf","file_size":4867547,"creator":"dernst"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10858","intvolume":" 11","title":"Enhanced thermoelectric performance of n-type Bi2Se3 nanosheets through Sn doping","ddc":["540"],"status":"public","publication_identifier":{"issn":["2079-4991"]},"month":"07","doi":"10.3390/nano11071827","language":[{"iso":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000676570000001"]},"oa":1,"project":[{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"}],"quality_controlled":"1","isi":1,"ec_funded":1,"file_date_updated":"2022-03-18T09:53:15Z","article_number":"1827","author":[{"last_name":"Li","first_name":"Mengyao","full_name":"Li, Mengyao"},{"last_name":"Zhang","first_name":"Yu","full_name":"Zhang, Yu"},{"full_name":"Zhang, Ting","last_name":"Zhang","first_name":"Ting"},{"full_name":"Zuo, Yong","first_name":"Yong","last_name":"Zuo"},{"full_name":"Xiao, Ke","first_name":"Ke","last_name":"Xiao"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"first_name":"Jordi","last_name":"Llorca","full_name":"Llorca, Jordi"},{"last_name":"Liu","first_name":"Yu","orcid":"0000-0001-7313-6740","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","full_name":"Liu, Yu"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}],"volume":11,"date_created":"2022-03-18T09:45:02Z","date_updated":"2023-08-17T07:08:30Z","year":"2021","acknowledgement":"M.L., Y.Z., T.Z. and K.X. thank the China Scholarship Council for their scholarship\r\nsupport.

WRC is crucial for Arp2/3 complex activation and the protrusion of branched actin filament networks. Moreover, Hem1 loss of function in immune cells causes autoimmune diseases in humans. Here, we show that genetic removal of Hem1 in macrophages diminishes frequency and efficacy of phagocytosis as well as phagocytic cup formation in addition to defects in lamellipodial protrusion and migration. Moreover, Hem1-null macrophages displayed strong defects in cell adhesion despite unaltered podosome formation and concomitant extracellular matrix degradation. Specifically, dynamics of both adhesion and de-adhesion as well as concomitant phosphorylation of paxillin and focal adhesion kinase (FAK) were significantly compromised. Accordingly, disruption of WRC function in non-hematopoietic cells coincided with both defects in adhesion turnover and altered FAK and paxillin phosphorylation. Consistently, platelets exhibited reduced adhesion and diminished integrin αIIbβ3 activation upon WRC removal. Interestingly, adhesion phenotypes, but not lamellipodia formation, were partially rescued by small molecule activation of FAK. A full rescue of the phenotype, including lamellipodia formation, required not only the presence of WRCs but also their binding to and activation by Rac. Collectively, our results uncover that WRC impacts on integrin-dependent processes in a FAK-dependent manner, controlling formation and dismantling of adhesions, relevant for properly grabbing onto extracellular surfaces and particles during cell edge expansion, like in migration or phagocytosis."}],"issue":"10","type":"journal_article","date_published":"2021-05-24T00:00:00Z","article_type":"original","page":"2051-2064.e8","publication":"Current Biology","citation":{"ama":"Stahnke S, Döring H, Kusch C, et al.

Recently Ghaffari, Kuhn and Uitto (FOCS 2019) introduced the class of component-stable low-space MPC algorithms, which are, informally, defined as algorithms for which the outputs reported by the nodes in different connected components are required to be independent. This very natural notion was introduced to capture most (if not all) of the known efficient MPC algorithms to date, and it was the first general class of MPC algorithms for which one can show non-trivial conditional lower bounds. In this paper we enhance the framework of component-stable algorithms and investigate its effect on the complexity of randomized and deterministic low-space MPC. Our key contributions include: 1) We revise and formalize the lifting approach of Ghaffari, Kuhn and Uitto. This requires a very delicate amendment of the notion of component stability, which allows us to fill in gaps in the earlier arguments. 2) We also extend the framework to obtain conditional lower bounds for deterministic algorithms and fine-grained lower bounds that depend on the maximum degree Δ. 3) We demonstrate a collection of natural graph problems for which non-component-stable algorithms break the conditional lower bound obtained for component-stable algorithms. This implies that, for both deterministic and randomized algorithms, component-stable algorithms are conditionally weaker than the non-component-stable ones.\r\n\r\nAltogether our results imply that component-stability might limit the computational power of the low-space MPC model, paving the way for improved upper bounds that escape the conditional lower bound setting of Ghaffari, Kuhn, and Uitto."}],"page":"481–491","citation":{"chicago":"Czumaj, Artur, Peter Davies, and Merav Parter. “Component Stability in Low-Space Massively Parallel Computation.” In Proceedings of the 2021 ACM Symposium on Principles of Distributed Computing, 481–491.

Among these products are stripped stars (or helium stars), which have their envelopes stripped from interactions with binary companions, leaving an exposed helium core. Previous work has suggested these stripped stars can dominate the Lyman Continuum (LyC) photon output of high-redshift, low-luminosity galaxies post-starburst. Other sources of hard radiation in the early universe include zero-metallicity Population iii stars, which may have similar spectral energy distribution (SED) properties to galaxies with radiation dominated by stripped-star emissions. Here, we use four metrics (the power-law exponent over wavelength intervals 240–500 Å, 600–900 Å, and 1200–2000 Å, and the ratio of total luminosity in FUV wavelengths to LyC wavelengths) to compare the SEDs of simulated galaxies with only single-stellar evolution, galaxies containing stripped stars, and galaxies containing Population iii stars, with four different initial mass functions (IMFs). We find that stripped stars significantly alter SEDs in the LyC range of galaxies at the epoch of reionization. SEDs in galaxies with stripped stars have lower power-law indices in the LyC range and lower FUV to LyC luminosity ratios. These differences in SEDs are present at all considered luminosities (${M}_{\\mathrm{UV}}\\gt -15$, AB system), and are most pronounced for lower-luminosity galaxies.

However, core-collapse supernovae simulations to date have focused almost exclusively on the evolution of single stars. We present a systematic simulation study of single and binary-stripped stars with the same initial mass as candidates for core-collapse supernovae (11–21 M⊙). Generally, we find that binary-stripped stars core tend to have a smaller compactness parameter, with a more prominent, deeper silicon/oxygen interface, and explode preferentially to the corresponding single stars of the same initial mass. Such a dichotomy of behavior between these two modes of evolution would have important implications for supernovae statistics, including the final neutron star masses, explosion energies, and nucleosynthetic yields. Binary-stripped remnants are also well poised to populate the possible mass gap between the heaviest neutron stars and the lightest black holes. Our work presents an improvement along two fronts, as we self-consistently account for the pre-collapse stellar evolution and the subsequent explosion outcome. Even so, our results emphasize the need for more detailed stellar evolutionary models to capture the sensitive nature of explosion outcome.","lang":"eng"}],"intvolume":" 916","status":"public","title":"Binary-stripped stars as core-collapse supernovae progenitors","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"13458","oa_version":"Preprint","publication_identifier":{"eissn":["2041-8213"],"issn":["2041-8205"]},"month":"07","quality_controlled":"1","oa":1,"external_id":{"arxiv":["2104.03317"]},"main_file_link":[{"url":"https://arxiv.org/abs/2104.03317","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.3847/2041-8213/ac0b42","article_number":"L5","extern":"1","publisher":"American Astronomical Society","publication_status":"published","year":"2021","volume":916,"date_created":"2023-08-03T10:11:45Z","date_updated":"2023-08-21T11:37:48Z","author":[{"last_name":"Vartanyan","first_name":"David","full_name":"Vartanyan, David"},{"full_name":"Laplace, Eva","first_name":"Eva","last_name":"Laplace"},{"full_name":"Renzo, Mathieu","first_name":"Mathieu","last_name":"Renzo"},{"full_name":"Götberg, Ylva Louise Linsdotter","first_name":"Ylva Louise Linsdotter","last_name":"Götberg","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","orcid":"0000-0002-6960-6911"},{"last_name":"Burrows","first_name":"Adam","full_name":"Burrows, Adam"},{"first_name":"Selma E.","last_name":"de Mink","full_name":"de Mink, Selma E."}]},{"extern":"1","article_number":"248","author":[{"first_name":"Luqian","last_name":"Wang","full_name":"Wang, Luqian"},{"first_name":"Douglas R.","last_name":"Gies","full_name":"Gies, Douglas R."},{"full_name":"Peters, Geraldine J.","last_name":"Peters","first_name":"Geraldine J."},{"full_name":"Götberg, Ylva Louise Linsdotter","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","orcid":"0000-0002-6960-6911","first_name":"Ylva Louise Linsdotter","last_name":"Götberg"},{"first_name":"S.

Observations of massive stars in open clusters younger than ∼8 Myr have shown that a majority of them are in binary systems, most of which will interact during their life. While these can be used as a proxy of the initial multiplicity properties, studying populations of massive stars older than ∼20 Myr allows us to probe the outcome of these interactions after a significant number of systems have experienced mass and angular momentum transfer and may even have merged.\r\n\r\nAims. Using multi-epoch integral-field spectroscopy, we aim to investigate the multiplicity properties of the massive-star population in the dense core of the ∼40 Myr old cluster NGC 330 in the Small Magellanic Cloud in order to search for possible imprints of stellar evolution on the multiplicity properties.\r\n\r\nMethods. We obtained six epochs of VLT/MUSE observations operated in wide-field mode with the extended wavelength setup and supported by adaptive optics. We extracted spectra and measured radial velocities for stars brighter than mF814W = 19. We identified single-lined spectroscopic binaries through significant RV variability with a peak-to-peak amplitude larger than 20 km s−1. We also identified double-lined spectroscopic binaries, and quantified the observational biases for binary detection. In particular, we took into account that binary systems with similar line strengths are difficult to detect in our data set.\r\n\r\nResults. The observed spectroscopic binary fraction among stars brighter than mF814W = 19 (approximately 5.5 M⊙ on the main sequence) is fSBobs = 13.2 ± 2.0%. Considering period and mass ratio ranges from log(P) = 0.15−3.5 (about 1.4 to 3160 d), q = 0.1−1.0, and a representative set of orbital parameter distributions, we find a bias-corrected close binary fraction of fcl = 34−7+8%. This fraction seems to decline for the fainter stars, which indicates either that the close binary fraction drops in the B-type domain, or that the period distribution becomes more heavily weighted toward longer orbital periods. We further find that both fractions vary strongly in different regions of the color-magnitude diagram, which corresponds to different evolutionary stages. This probably reveals the imprint of the binary history of different groups of stars. In particular, we find that the observed spectroscopic binary fraction of Be stars (fSBobs = 2 ± 2%) is significantly lower than that of B-type stars (fSBobs = 9 ± 2%).\r\n\r\nConclusions. We provide the first homogeneous radial velocity study of a large sample of B-type stars at a low metallicity ([Fe/H] ≲ −1.0). The overall bias-corrected close binary fraction (log(P) < 3.5 d) of the B-star population in NGC 330 is lower than the fraction reported for younger Galactic and Large Magellanic Cloud clusters in previous works. More data are needed, however, to establish whether the observed differences are caused by an age or a metallicity effect.","lang":"eng"}],"type":"journal_article"},{"oa":1,"external_id":{"arxiv":["2102.05036"]},"main_file_link":[{"url":"https://doi.org/10.1051/0004-6361/202140506","open_access":"1"}],"quality_controlled":"1","doi":"10.1051/0004-6361/202140506","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1432-0746"],"issn":["0004-6361"]},"month":"12","year":"2021","publisher":"EDP Sciences","publication_status":"published","author":[{"full_name":"Laplace, E.","last_name":"Laplace","first_name":"E."},{"full_name":"Justham, S.","last_name":"Justham","first_name":"S."},{"full_name":"Renzo, M.","last_name":"Renzo","first_name":"M."},{"full_name":"Götberg, Ylva Louise Linsdotter","first_name":"Ylva Louise Linsdotter","last_name":"Götberg","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","orcid":"0000-0002-6960-6911"},{"full_name":"Farmer, R.","first_name":"R.","last_name":"Farmer"},{"full_name":"Vartanyan, D.","last_name":"Vartanyan","first_name":"D."},{"full_name":"de Mink, S.

Donor stars in binary systems can lose most of their hydrogen-rich envelopes through mass transfer. As a result, not only are the surface properties affected, but so is the core structure. However, most calculations of the core-collapse properties of massive stars rely on single-star models. We present a systematic study of the difference between the pre-supernova structures of single stars and stars of the same initial mass (11–21 M⊙) that have been stripped due to stable post-main-sequence mass transfer at solar metallicity. We present the pre-supernova core composition with novel diagrams that give an intuitive representation of the isotope distribution. As shown in previous studies, at the edge of the carbon-oxygen core, the binary-stripped star models contain an extended gradient of carbon, oxygen, and neon. This layer remains until core collapse and is more extended in mass for higher initial stellar masses. It originates from the receding of the convective helium core during core helium burning in binary-stripped stars, which does not occur in single-star models. We find that this same evolutionary phase leads to systematic differences in the final density and nuclear energy generation profiles. Binary-stripped star models have systematically higher total masses of carbon at the moment of core collapse compared to single-star models, which likely results in systematically different supernova yields. In about half of our models, the silicon-burning and oxygen-rich layers merge after core silicon burning. We discuss the implications of our findings for the “explodability”, supernova observations, and nucleosynthesis of these stars.

These modify the appearance, structure, and future evolution of both stars. We compute the evolution of a 100-day-period binary, consisting initially of a 25 M⊙ star and a 17 M⊙ star, which experiences stable mass transfer. We focus on the impact of mass accretion on the surface composition, internal rotation, and structure of the accretor. To anchor our models, we show that our accretor broadly reproduces the properties of ζ Ophiuchi, which has long been proposed to have accreted mass before being ejected as a runaway star when the companion exploded. We compare our accretor to models of single rotating stars and find that the later and stronger spin-up provided by mass accretion produces significant differences. Specifically, the core of the accretor retains higher spin at the end of the main sequence, and a convective layer develops that changes its density profile. Moreover, the surface of the accretor star is polluted by CNO-processed material donated by the companion. Our models show effects of mass accretion in binaries that are not captured in single rotating stellar models. This possibly impacts the further evolution (either in a binary or as single stars), the final collapse, and the resulting spin of the compact object."}],"citation":{"mla":"Renzo, M., and Ylva Louise Linsdotter Götberg. “Evolution of Accretor Stars in Massive Binaries: Broader Implications from Modeling ζ Ophiuchi.” The Astrophysical Journal, vol. 923, no. 2, 277, American Astronomical Society, 2021, doi:10.3847/1538-4357/ac29c5.","short":"M.

In particular, we focus on the process of nonperturbative high-order harmonic generation from the paradigmatic three-dimensional topological insulator bismuth selenide (Bi2Se3) subjected to intense midinfrared laser fields. We analyze the contributions from the spin-orbit-coupled bulk states and the topological surface bands separately and reveal a major difference in how their harmonic yields depend on the ellipticity of the laser field. Bulk harmonics show a monotonic decrease in their yield as the ellipticity increases, in a manner reminiscent of high harmonic generation in gaseous media. However, the surface contribution exhibits a highly nontrivial dependence, culminating with a maximum for circularly polarized fields. We attribute the observed anomalous behavior to (i) the enhanced amplitude and the circular pattern of the interband dipole and the Berry connections in the vicinity of the Dirac point and (ii) the influence of the higher-order, hexagonal warping terms in the Hamiltonian, which are responsible for the hexagonal deformation of the energy surface at higher momenta. The latter are associated directly with spin-orbit-coupling parameters. Our results thus establish the sensitivity of strong-field-driven high harmonic emission to the topology of the band structure as well as to the manifestations of spin-orbit interaction.","lang":"eng"}],"issue":"2","type":"journal_article","oa_version":"Preprint","title":"Strong-field physics in three-dimensional topological insulators","status":"public","intvolume":" 103","_id":"13997","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"01","article_processing_charge":"No","scopus_import":"1","date_published":"2021-02-01T00:00:00Z","article_type":"original","publication":"Physical Review A","citation":{"ama":"Baykusheva DR, Chacón A, Kim D, Kim DE, Reis DA, Ghimire S.

We find delays of up to ∼600 as in the ionization out of the highest occupied molecular orbital (HOMO) with a strong dependence on the emission direction and a pronounced asymmetry along the dissociation axis. Comparison with quantum-scattering calculations traces the asymmetries to the interference of a small subset of partial waves at low kinetic energies and, additionally, to the interference of two overlapping shape resonances in the HOMO-1 channel.

The UVEX design has two co-aligned wide-field imagers operating in the FUV and NUV and a powerful broadband medium resolution spectrometer. In its two-year baseline mission, UVEX will perform a multi-cadence synoptic all-sky survey 50/100 times deeper than GALEX in the NUV/FUV, cadenced surveys of the Large and Small Magellanic Clouds, rapid target of opportunity followup, as well as spectroscopic followup of samples of stars and galaxies. The science program is built around three pillars. First, UVEX will explore the low-mass, low-metallicity galaxy frontier through imaging and spectroscopic surveys that will probe key aspects of the evolution of galaxies by understanding how star formation and stellar evolution at low metallicities affect the growth and evolution of low-metallicity, low-mass galaxies in the local universe. Such galaxies contain half the mass in the local universe, and are analogs for the first galaxies, but observed at distances that make them accessible to detailed study. Second, UVEX will explore the dynamic universe through time-domain surveys and prompt spectroscopic followup capability will probe the environments, energetics, and emission processes in the early aftermaths of gravitational wave-discovered compact object mergers, discover hot, fast UV transients, and diagnose the early stages of stellar explosions. Finally, UVEX will become a key community resource by leaving a large all-sky legacy data set, enabling a wide range of scientific studies and filling a gap in the new generation of wide-field, sensitive optical and infrared surveys provided by the Rubin, Euclid, and Roman observatories. This paper discusses the scientific potential of UVEX, and the broad scientific program."}],"extern":"1","article_number":"2111.15608","type":"preprint","doi":"10.48550/arXiv.2111.15608","date_published":"2021-11-30T00:00:00Z","language":[{"iso":"eng"}],"publication":"arXiv","citation":{"short":"S.R.

Formulating four conditions concerning the form of the implicit equation, we first show that these conditions describe a maximal monotone p-coercive graph. We then establish the global-in-time and large-data existence of a (weak) solution and its uniqueness. To this end, we adopt and significantly generalize Minty’s method of monotone mappings.

DQPTs are defined by nonanalyticities in the return amplitude and are present in many models. In some cases, DQPTs can be related to equilibrium concepts, such as order parameters, yet their universal description is an open question. In this Letter, we provide first steps toward a classification of DQPTs by using a matrix product state description of unitary dynamics in the thermodynamic limit. This allows us to distinguish the two limiting cases of “precession” and “entanglement” DQPTs, which are illustrated using an analytical description in the quantum Ising model. While precession DQPTs are characterized by a large entanglement gap and are semiclassical in their nature, entanglement DQPTs occur near avoided crossings in the entanglement spectrum and can be distinguished by a complex pattern of nonlocal correlations. We demonstrate the existence of precession and entanglement DQPTs beyond Ising models, discuss observables that can distinguish them, and relate their interplay to complex DQPT phenomenology.","lang":"eng"}],"intvolume":" 126","title":"Entanglement view of dynamical quantum phase transitions","status":"public","ddc":["530"],"_id":"9048","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file":[{"creator":"dernst","content_type":"application/pdf","file_size":398075,"access_level":"open_access","file_name":"2021_PhysicalRevLett_DeNicola.pdf","success":1,"checksum":"d9acbc502390ed7a97e631d23ae19ecd","date_created":"2021-02-03T12:47:04Z","date_updated":"2021-02-03T12:47:04Z","file_id":"9074","relation":"main_file"}],"oa_version":"Published Version","keyword":["General Physics and Astronomy"],"article_processing_charge":"Yes","has_accepted_license":"1","day":"29","article_type":"original","citation":{"ista":"De Nicola S, Michailidis A, Serbyn M. 2021.

To elucidate the molecular mechanism of 3'-Phosphoinositide-Dependent Protein Kinase1 (PDK1), a master regulator that is essential throughout eukaryotic growth and development, we employed a forward genetic approach to screen for suppressors of the loss-of-function T-DNA insertion double mutant pdk1.1 pdk1.2 in Arabidopsis thaliana. Notably, the severe growth attenuation of pdk1.1 pdk1.2 was rescued by sop21 (suppressor of pdk1.1 pdk1.2), which harbours a loss-of-function mutation in PELOTA1 (PEL1). PEL1 is a homologue of mammalian PELOTA and yeast (Saccharomyces cerevisiae) DOM34p, which each form a heterodimeric complex with the GTPase HBS1 (HSP70 SUBFAMILY B SUPPRESSOR1, also called SUPERKILLER PROTEIN7, SKI7), a protein that is responsible for ribosomal rescue and thereby assures the quality and fidelity of mRNA molecules during translation. Genetic analysis further revealed that a dysfunctional PEL1-HBS1 complex failed to degrade the T-DNA-disrupted PDK1 transcripts, which were truncated but functional, and thus rescued the growth and developmental defects of pdk1.1 pdk1.2. Our studies demonstrated the functionality of a homologous PELOTA-HBS1 complex and identified its essential regulatory role in plants, providing insights into the mechanism of mRNA quality control.","lang":"eng"}],"issue":"4","_id":"9368","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"mRNA surveillance complex PELOTA-HBS1 eegulates phosphoinositide-sependent protein kinase1 and plant growth","status":"public","intvolume":" 186","oa_version":"Published Version","month":"04","publication_identifier":{"eissn":["1532-2548"],"issn":["0032-0889"]},"main_file_link":[{"url":"https://doi.org/10.1093/plphys/kiab199","open_access":"1"}],"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png"},"external_id":{"isi":["000703922000025"],"pmid":["33930167"]},"oa":1,"isi":1,"quality_controlled":"1","project":[{"_id":"256FEF10-B435-11E9-9278-68D0E5697425","grant_number":"723-2015","name":"Long Term Fellowship"},{"name":"Molecular mechanisms of endocytic cargo recognition in plants","call_identifier":"FWF","_id":"26538374-B435-11E9-9278-68D0E5697425","grant_number":"I03630"}],"doi":"10.1093/plphys/kiab199","language":[{"iso":"eng"}],"year":"2021","acknowledgement":"We gratefully acknowledge the Arabidopsis Biological Resource Centre (ABRC) for providing T-DNA insertional mutants, and Prof. Remko Offringa for sharing published seeds.

Arabidopsis mutants lacking PID, a kinase that phosphorylates PINs, or the MAB4/MEL proteins of unknown molecular function display PIN polarity defects and phenocopy pin mutants, but mechanistic insights into how these factors convey PIN polarity are missing. Here, by combining protein biochemistry with quantitative live-cell imaging, we demonstrate that PINs, MAB4/MELs, and AGC kinases interact in the same complex at the plasma membrane. MAB4/MELs are recruited to the plasma membrane by the PINs and in concert with the AGC kinases maintain PIN polarity through limiting lateral diffusion-based escape of PINs from the polar domain. The PIN-MAB4/MEL-PID protein complex has self-reinforcing properties thanks to positive feedback between AGC kinase-mediated PIN phosphorylation and MAB4/MEL recruitment. We thus uncover the molecular mechanism by which AGC kinases and MAB4/MEL proteins regulate PIN localization and plant development.","lang":"eng"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"9290","intvolume":" 31","status":"public","title":"AGC kinases and MAB4/MEL proteins maintain PIN polarity by limiting lateral diffusion in plant cells","ddc":["580"],"file":[{"success":1,"checksum":"b1723040ecfd8c81194185472eb62546","date_updated":"2021-04-01T10:53:42Z","date_created":"2021-04-01T10:53:42Z","file_id":"9303","relation":"main_file","creator":"dernst","file_size":4324371,"content_type":"application/pdf","access_level":"open_access","file_name":"2021_CurrentBiology_Glanc.pdf"}],"oa_version":"Published Version","has_accepted_license":"1","article_processing_charge":"No","day":"10","citation":{"mla":"Glanc, Matous, et al. “AGC Kinases and MAB4/MEL Proteins Maintain PIN Polarity by Limiting Lateral Diffusion in Plant Cells.” Current Biology, vol. 31, no. 9, Elsevier, 2021, pp. 1918–30, doi:10.1016/j.cub.2021.02.028.","short":"M.

Here, we show that MEMBRANE ASSOCIATED KINASE REGULATOR2 (MAKR2) controls the pace of the root gravitropic response. We found that MAKR2 is required for the PIN2 asymmetry during gravitropism by acting as a negative regulator of the cell-surface signaling mediated by the receptor-like kinase TRANSMEMBRANE KINASE1 (TMK1).2,7, 8, 9, 10 Furthermore, we show that the MAKR2 inhibitory effect on TMK1 signaling is antagonized by auxin itself, which triggers rapid MAKR2 membrane dissociation in a TMK1-dependent manner. Our findings suggest that the timing of the root gravitropic response is orchestrated by the reversible inhibition of the TMK1 signaling pathway at the cell surface.","lang":"eng"}],"issue":"1","type":"journal_article","date_published":"2021-01-11T00:00:00Z","article_type":"original","publication":"Current Biology","citation":{"mla":"Marquès-Bueno, MM, et al. “Auxin-Regulated Reversible Inhibition of TMK1 Signaling by MAKR2 Modulates the Dynamics of Root Gravitropism.” Current Biology, vol. 31, no. 1, Elsevier, 2021, doi:10.1016/j.cub.2020.10.011.","short":"M.

Current understanding states that the partition between surface adsorbed and dissolved lithium superoxide governs whether Li2O2 grows as a conformal surface film or larger particles, leading to low or high capacities, respectively. However, better understanding governing factors for Li2O2 packing density and capacity requires structural sensitive in situ metrologies. Here, we establish in situ small- and wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2 phase evolution with atomic to submicrometer resolution during cycling a custom-built in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving rich quantitative structural information from complex multiphase systems. Surprisingly, we find that features are absent that would point at a Li2O2 surface film formed via two consecutive electron transfers, even in poorly solvating electrolytes thought to be prototypical for surface growth. All scattering data can be modeled by stacks of thin Li2O2 platelets potentially forming large toroidal particles. Li2O2 solution growth is further justified by rotating ring-disk electrode measurements and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2 particles, but there is no transition to an electronically passivating, conformal Li2O2 coating. Hence, mass transport of reactive species rather than electronic transport through a Li2O2 film limits the discharge capacity. Provided that species mobilities and carbon surface areas are high, this allows for high discharge capacities even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism ought to be reconsidered."}],"issue":"14","type":"journal_article","oa_version":"Preprint","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"9301","status":"public","title":"In situ small-angle X-ray scattering reveals solution phase discharge of Li–O2 batteries with weakly solvating electrolytes","intvolume":" 118","month":"04","publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"doi":"10.1073/pnas.2021893118","acknowledged_ssus":[{"_id":"EM-Fac"}],"language":[{"iso":"eng"}],"oa":1,"main_file_link":[{"url":"https://doi.org/10.26434/chemrxiv.11447775","open_access":"1"}],"external_id":{"isi":["000637398300050"]},"quality_controlled":"1","isi":1,"article_number":"e2021893118","author":[{"last_name":"Prehal","first_name":"Christian","full_name":"Prehal, Christian"},{"last_name":"Samojlov","first_name":"Aleksej","full_name":"Samojlov, Aleksej"},{"full_name":"Nachtnebel, Manfred","last_name":"Nachtnebel","first_name":"Manfred"},{"orcid":"0000-0001-6206-4200","id":"36DB3A20-F248-11E8-B48F-1D18A9856A87","last_name":"Lovicar","first_name":"Ludek","full_name":"Lovicar, Ludek"},{"full_name":"Kriechbaum, Manfred","last_name":"Kriechbaum","first_name":"Manfred"},{"first_name":"Heinz","last_name":"Amenitsch","full_name":"Amenitsch, Heinz"},{"full_name":"Freunberger, Stefan Alexander","first_name":"Stefan Alexander","last_name":"Freunberger","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","orcid":"0000-0003-2902-5319"}],"date_created":"2021-03-31T07:00:01Z","date_updated":"2023-09-05T13:27:18Z","volume":118,"acknowledgement":"S.A.F. and C.P. are indebted to the European Research Council under the European Union's Horizon 2020 research and innovation program (Grant Agreement No. 636069), the Austrian Federal Ministry of Science, Research and Economy, and the Austrian Research Promotion Agency (Grant No. 845364).

Upon increasing the salt concentration towards superconcentration the onset of the oxygen evolution reaction (OER) shifts more significantly than the hydrogen evolution reaction (HER) does. The OER shift has been explained by the accumulation of hydrophobic anions blocking water access to the electrode surface, hence by double layer theory. Here we demonstrate that the processes during oxidation are much more complex, involving OER, carbon and salt decomposition by OER intermediates, and salt precipitation upon local oversaturation. The positive shift in the onset potential of oxidation currents was elucidated by combining several advanced analysis techniques: rotating ring-disk electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron spectroscopy, using both dilute and superconcentrated electrolytes. The results demonstrate the importance of reactive OER intermediates and surface films for electrolyte and electrode stability and motivate further studies of the nature of the electrode.","lang":"eng"}],"intvolume":" 168","title":"Investigation of electrochemical and chemical processes occurring at positive potentials in “Water-in-Salt” electrolytes","status":"public","_id":"9447","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"None","keyword":["Renewable Energy","Sustainability and the Environment","Electrochemistry","Materials Chemistry","Electronic","Optical and Magnetic Materials","Surfaces","Coatings and Films","Condensed Matter Physics"],"article_processing_charge":"No","day":"01","citation":{"apa":"Maffre, M., Bouchal, R., Freunberger, S.

Priming is initiated at a heterologous cell–cell contact, the immunological synapse (IS). While it is established that F-actin dynamics regulates signaling at the T cell side of the contact, little is known about the cytoskeletal contribution on the DC side. Here, we show that the DC actin cytoskeleton is decisive for the formation of a multifocal synaptic structure, which correlates with T cell priming efficiency. DC actin at the IS appears in transient foci that are dynamized by the WAVE regulatory complex (WRC). The absence of the WRC in DCs leads to stabilized contacts with T cells, caused by an increase in ICAM1-integrin–mediated cell–cell adhesion. This results in lower numbers of activated and proliferating T cells, demonstrating an important role for DC actin in the regulation of immune synapse functionality."}],"issue":"4","publication":"Journal of Cell Biology","citation":{"chicago":"Leithner, Alexander F, LM Altenburger, R Hauschild, Frank P Assen, K Rottner, Stradal TEB, A Diz-Muñoz, JV Stein, and Michael K Sixt. “Dendritic Cell Actin Dynamics Control Contact Duration and Priming Efficiency at the Immunological Synapse.” Journal of Cell Biology.

While many of these endeavors take advantage of model systems, consideration will also be given to advances in our understanding of activity in nascent human circuits.

Two popular solutions are based on a linear estimator 𝑥𝑥^L and a spectral estimator 𝑥𝑥^s. The former is a data-dependent linear combination of the columns of the measurement matrix, and its analysis is quite simple. The latter is the principal eigenvector of a data-dependent matrix, and a recent line of work has studied its performance. In this paper, we show how to optimally combine 𝑥𝑥^L and 𝑥𝑥^s. At the heart of our analysis is the exact characterization of the empirical joint distribution of (𝑥𝑥,𝑥𝑥^L,𝑥𝑥^s) in the high-dimensional limit. This allows us to compute the Bayes-optimal combination of 𝑥𝑥^L and 𝑥𝑥^s, given the limiting distribution of the signal 𝑥𝑥. When the distribution of the signal is Gaussian, then the Bayes-optimal combination has the form 𝜃𝑥𝑥^L+𝑥𝑥^s and we derive the optimal combination coefficient. In order to establish the limiting distribution of (𝑥𝑥,𝑥𝑥^L,𝑥𝑥^s), we design and analyze an approximate message passing algorithm whose iterates give 𝑥𝑥^L and approach 𝑥𝑥^s. Numerical simulations demonstrate the improvement of the proposed combination with respect to the two methods considered separately.","lang":"eng"}],"oa":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000685721000001"],"arxiv":["2008.03326"]},"isi":1,"quality_controlled":"1","project":[{"name":"IST Austria Open Access Fund","_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854"}],"doi":"10.1007/s10208-021-09531-x","language":[{"iso":"eng"}],"month":"08","publication_identifier":{"eissn":["1615-3383"],"issn":["1615-3375"]},"acknowledgement":"M.

We first give a categorification of the mapper graph and the Reeb graph by interpreting them in terms of cosheaves and stratified covers of the real line R. We then introduce a variant of the classic mapper graph of Singh et al. (in: Eurographics symposium on point-based graphics, 2007), referred to as the enhanced mapper graph, and demonstrate that such a construction approximates the Reeb graph of (X,f) when it is applied to points randomly sampled from a probability density function concentrated on (X,f). Our techniques are based on the interleaving distance of constructible cosheaves and topological estimation via kernel density estimates. Following Munch and Wang (In: 32nd international symposium on computational geometry, volume 51 of Leibniz international proceedings in informatics (LIPIcs), Dagstuhl, Germany, pp 53:1–53:16, 2016), we first show that the mapper graph of (X,f), a constructible R-space (with a fixed open cover), approximates the Reeb graph of the same space. We then construct an isomorphism between the mapper of (X,f) to the mapper of a super-level set of a probability density function concentrated on (X,f). Finally, building on the approach of Bobrowski et al. (Bernoulli 23(1):288–328, 2017b), we show that, with high probability, we can recover the mapper of the super-level set given a sufficiently large sample. Our work is the first to consider the mapper construction using the theory of cosheaves in a probabilistic setting. It is part of an ongoing effort to combine sheaf theory, probability, and statistics, to support topological data analysis with random data.","lang":"eng"}],"type":"journal_article","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"9112","date_created":"2021-02-11T14:43:59Z","date_updated":"2021-02-11T14:43:59Z","checksum":"3f02e9d47c428484733da0f588a3c069","success":1,"file_name":"2020_JourApplCompTopology_Brown.pdf","access_level":"open_access","file_size":2090265,"content_type":"application/pdf","creator":"dernst"}],"_id":"9111","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","intvolume":" 5","ddc":["510"],"title":"Probabilistic convergence and stability of random mapper graphs","status":"public","has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","day":"01","scopus_import":"1","date_published":"2021-03-01T00:00:00Z","citation":{"ama":"Brown A, Bobrowski O, Munch E, Wang B.

One possible constraint is the opportunity for allopatric divergence. In 1981, Felsenstein used a simple and elegant model to ask if there might also be genetic constraints. He showed that progress towards speciation could be described by the build‐up of linkage disequilibrium among divergently selected loci and between these loci and those contributing to other forms of reproductive isolation. Therefore, speciation is opposed by recombination, because it tends to break down linkage disequilibria. Felsenstein then introduced a crucial distinction between “two‐allele” models, which are subject to this effect, and “one‐allele” models, which are free from the recombination constraint. These fundamentally important insights have been the foundation for both empirical and theoretical studies of speciation ever since.","lang":"eng"}],"type":"journal_article","date_published":"2021-04-19T00:00:00Z","citation":{"apa":"Butlin, R.

It allows for the identification of genomic regions underlying barriers to gene flow. It also provides insights into spatial patterns of allele frequency change, informing about the interplay between environmental factors, dispersal and selection. However, when only a single hybrid zone is analysed, it is difficult to separate patterns generated by selection from those resulting from chance. Therefore, it is beneficial to look for repeatable patterns across replicate hybrid zones in the same system. We applied this approach to the marine snail Littorina saxatilis, which contains two ecotypes, adapted to wave-exposed rocks vs. high-predation boulder fields. The existence of numerous hybrid zones between ecotypes offered the opportunity to test for the repeatability of genomic architectures and spatial patterns of divergence. We sampled and phenotyped snails from seven replicate hybrid zones on the Swedish west coast and genotyped them for thousands of single nucleotide polymorphisms. Shell shape and size showed parallel clines across all zones. Many genomic regions showing steep clines and/or high differentiation were shared among hybrid zones, consistent with a common evolutionary history and extensive gene flow between zones, and supporting the importance of these regions for divergence. In particular, we found that several large putative inversions contribute to divergence in all locations. Additionally, we found evidence for consistent displacement of clines from the boulder–rock transition. Our results demonstrate patterns of spatial variation that would not be accessible without continuous spatial sampling, a large genomic data set and replicate hybrid zones.","lang":"eng"}],"page":"3797-3814","article_type":"original","citation":{"mla":"Westram, Anja M., et al. “Using Replicate Hybrid Zones to Understand the Genomic Basis of Adaptive Divergence.” Molecular Ecology, vol. 30, no. 15, Wiley, 2021, pp. 3797–814, doi:10.1111/mec.15861.","short":"A.M.

Most carbon entering the pathway is incorporated into lignin. Although several phenylpropanoid pathway mutants show seedling growth arrest, the role for lignin in seedling growth and development is unexplored.\r\n• We use complementary pharmacological and genetic approaches to block CINNAMATE‐4‐HYDROXYLASE (C4H) functionality in Arabidopsis seedlings and a set of molecular and biochemical techniques to investigate the underlying phenotypes.\r\n• Blocking C4H resulted in reduced lateral rooting and increased adventitious rooting apically in the hypocotyl. These phenotypes coincided with an inhibition in auxin transport. The upstream accumulation in cis‐cinnamic acid was found to likely cause polar auxin transport inhibition. Conversely, a downstream depletion in lignin perturbed phloem‐mediated auxin transport. Restoring lignin deposition effectively reestablished phloem transport and, accordingly, auxin homeostasis.\r\n• Our results show that the accumulation of bioactive intermediates and depletion in lignin jointly cause the aberrant phenotypes upon blocking C4H, and demonstrate that proper deposition of lignin is essential for the establishment of auxin distribution in seedlings. Our data position the phenylpropanoid pathway and lignin in a new physiological framework, consolidating their importance in plant growth and development."}],"type":"journal_article","date_published":"2021-03-17T00:00:00Z","citation":{"apa":"El Houari, I., Van Beirs, C., Arents, H., Han, H., Chanoca, A., Opdenacker, D., … Vanholme, B.

Growth-promoting hormones and defence signalling fine tune plant development antagonistically. During host-pathogen interactions, this defence-growth trade-off is mediated by the counteractive effects of the defence hormone salicylic acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism of SA regulating auxin signalling by constraining the plasma membrane dynamics of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation. Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced heterogeneous surface condensation disrupted asymmetric auxin distribution and the resultant gravitropic response. Our results demonstrated a defence-growth trade-off mechanism by which SA signalling crosstalked with auxin transport by concentrating membrane-resident PIN2 into heterogeneous compartments.","lang":"eng"}],"issue":"2","type":"journal_article","file":[{"file_name":"2021_NewPhytologist_Ke.pdf","access_level":"open_access","creator":"dernst","file_size":3674502,"content_type":"application/pdf","file_id":"9085","relation":"main_file","date_updated":"2021-02-04T09:53:16Z","date_created":"2021-02-04T09:53:16Z","success":1,"checksum":"d36b6a8c6fafab66264e0d27114dae63"}],"oa_version":"Published Version","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"8608","status":"public","ddc":["580"],"title":"Salicylic acid regulates PIN2 auxin transporter hyper-clustering and root gravitropic growth via Remorin-dependent lipid nanodomain organization in Arabidopsis thaliana","intvolume":" 229","month":"01","publication_identifier":{"eissn":["1469-8137"],"issn":["0028-646x"]},"doi":"10.1111/nph.16915","language":[{"iso":"eng"}],"external_id":{"pmid":["32901934"],"isi":["000573568000001"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"quality_controlled":"1","isi":1,"file_date_updated":"2021-02-04T09:53:16Z","author":[{"first_name":"M","last_name":"Ke","full_name":"Ke, M"},{"full_name":"Ma, Z","last_name":"Ma","first_name":"Z"},{"full_name":"Wang, D","first_name":"D","last_name":"Wang"},{"full_name":"Sun, Y","first_name":"Y","last_name":"Sun"},{"full_name":"Wen, C","last_name":"Wen","first_name":"C"},{"first_name":"D","last_name":"Huang","full_name":"Huang, D"},{"last_name":"Chen","first_name":"Z","full_name":"Chen, Z"},{"last_name":"Yang","first_name":"L","full_name":"Yang, L"},{"full_name":"Tan, Shutang","last_name":"Tan","first_name":"Shutang","orcid":"0000-0002-0471-8285","id":"2DE75584-F248-11E8-B48F-1D18A9856A87"},{"first_name":"R","last_name":"Li","full_name":"Li, R"},{"full_name":"Friml, Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","first_name":"Jiří","last_name":"Friml"},{"first_name":"Y","last_name":"Miao","full_name":"Miao, Y"},{"full_name":"Chen, X","last_name":"Chen","first_name":"X"}],"date_created":"2020-10-05T12:45:36Z","date_updated":"2023-09-05T16:06:24Z","volume":229,"acknowledgement":"This work was supported by the National Key Research andDevelopment Programme of China (2017YFA0506100), theNational Natural Science Foundation of China (31870170 and31701168), and the Fok Ying Tung Education Foundation(161027) to XC; NTU startup grant (M4081533) and NIM/01/2016 (NTU, Singapore) to YM.

The k-fold cover for some discrete input point set consists of the space where at least k balls of radius r around the input points overlap. Persistence is a notion that captures, in some sense, the topology of the shape underlying the input. While persistence is usually computed for the union of balls, the k-fold cover is of interest as it captures local density,\r\nand thus might approximate the shape of the input better if the input data is noisy. To compute persistence of these k-fold covers, we need a discretization that is provided by higher-order Delaunay mosaics. We present and implement a simple and efficient algorithm for the computation of higher-order Delaunay mosaics, and use it to give experimental results for their combinatorial properties. The algorithm makes use of a new geometric structure, the rhomboid tiling. It contains the higher-order Delaunay mosaics as slices, and by introducing a filtration\r\nfunction on the tiling, we also obtain higher-order α-shapes as slices. These allow us to compute persistence of the multi-covers for varying radius r; the computation for varying k is less straight-foward and involves the rhomboid tiling directly. We apply our algorithms to experimental sphere packings to shed light on their structural properties. Finally, inspired by periodic structures in packings and materials, we propose and implement an algorithm for periodic Delaunay triangulations to be integrated into the Computational Geometry Algorithms Library (CGAL), and discuss the implications on persistence for periodic data sets."}],"_id":"9056","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","status":"public","ddc":["006","514","516"],"title":"Multi-cover persistence and Delaunay mosaics","file":[{"checksum":"bcf27986147cab0533b6abadd74e7629","date_created":"2021-02-02T14:09:25Z","date_updated":"2021-02-03T10:37:28Z","file_id":"9063","relation":"source_file","creator":"patrickd","file_size":13446994,"content_type":"application/zip","access_level":"closed","file_name":"thesis_source.zip"},{"relation":"main_file","file_id":"9064","checksum":"9cc8af266579a464385bbe2aff6af606","success":1,"date_created":"2021-02-02T14:09:18Z","date_updated":"2021-02-02T14:09:18Z","access_level":"open_access","file_name":"thesis_pdfA2b.pdf","content_type":"application/pdf","file_size":5210329,"creator":"patrickd"}],"oa_version":"Published Version","month":"02","publication_identifier":{"issn":["2663-337X"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"doi":"10.15479/AT:ISTA:9056","degree_awarded":"PhD","supervisor":[{"orcid":"0000-0002-9823-6833","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","last_name":"Edelsbrunner","first_name":"Herbert","full_name":"Edelsbrunner, Herbert"}],"language":[{"iso":"eng"}],"place":"Klosterneuburg","file_date_updated":"2021-02-03T10:37:28Z","year":"2021","publication_status":"published","department":[{"_id":"HeEd"},{"_id":"GradSch"}],"publisher":"Institute of Science and Technology Austria","author":[{"orcid":"0000-0002-8882-5116","id":"464B40D6-F248-11E8-B48F-1D18A9856A87","last_name":"Osang","first_name":"Georg F","full_name":"Osang, Georg F"}],"related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"187"},{"status":"public","relation":"part_of_dissertation","id":"8703"}]},"date_updated":"2023-09-07T13:29:01Z","date_created":"2021-02-02T14:11:06Z"},{"oa_version":"Published Version","file":[{"file_id":"9043","relation":"main_file","date_updated":"2021-01-25T14:19:03Z","date_created":"2021-01-25T14:19:03Z","success":1,"checksum":"5a93658a5f19478372523ee232887e2b","file_name":"thesis.pdf","access_level":"open_access","creator":"gcipollo","file_size":4127796,"content_type":"application/pdf"},{"creator":"gcipollo","content_type":"application/zip","file_size":12775206,"access_level":"closed","file_name":"Thesis_files.zip","checksum":"e8270eddfe6a988e92a53c88d1d19b8c","date_created":"2021-01-25T14:19:10Z","date_updated":"2021-01-25T14:19:10Z","file_id":"9044","relation":"source_file"}],"ddc":["510"],"status":"public","title":"Fluctuations in the spectrum of random matrices","_id":"9022","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","abstract":[{"lang":"eng","text":"In the first part of the thesis we consider Hermitian random matrices. Firstly, we consider sample covariance matrices XX∗ with X having independent identically distributed (i.i.d.) centred entries. We prove a Central Limit Theorem for differences of linear statistics of XX∗ and its minor after removing the first column of X. Secondly, we consider Wigner-type matrices and prove that the eigenvalue statistics near cusp singularities of the limiting density of states are universal and that they form a Pearcey process. Since the limiting eigenvalue distribution admits only square root (edge) and cubic root (cusp) singularities, this concludes the third and last remaining case of the Wigner-Dyson-Mehta universality conjecture. The main technical ingredients are an optimal local law at the cusp, and the proof of the fast relaxation to equilibrium of the Dyson Brownian motion in the cusp regime.\r\nIn the second part we consider non-Hermitian matrices X with centred i.i.d. entries. We normalise the entries of X to have variance N −1. It is well known that the empirical eigenvalue density converges to the uniform distribution on the unit disk (circular law). In the first project, we prove universality of the local eigenvalue statistics close to the edge of the spectrum. This is the non-Hermitian analogue of the TracyWidom universality at the Hermitian edge. Technically we analyse the evolution of the spectral distribution of X along the Ornstein-Uhlenbeck flow for very long time\r\n(up to t = +∞). In the second project, we consider linear statistics of eigenvalues for macroscopic test functions f in the Sobolev space H2+ϵ and prove their convergence to the projection of the Gaussian Free Field on the unit disk. We prove this result for non-Hermitian matrices with real or complex entries. The main technical ingredients are: (i) local law for products of two resolvents at different spectral parameters, (ii) analysis of correlated Dyson Brownian motions.\r\nIn the third and final part we discuss the mathematically rigorous application of supersymmetric techniques (SUSY ) to give a lower tail estimate of the lowest singular value of X − z, with z ∈ C. More precisely, we use superbosonisation formula to give an integral representation of the resolvent of (X − z)(X − z)∗ which reduces to two and three contour integrals in the complex and real case, respectively. The rigorous analysis of these integrals is quite challenging since simple saddle point analysis cannot be applied (the main contribution comes from a non-trivial manifold). Our result\r\nimproves classical smoothing inequalities in the regime |z| ≈ 1; this result is essential to prove edge universality for i.i.d. non-Hermitian matrices."}],"alternative_title":["ISTA Thesis"],"type":"dissertation","date_published":"2021-01-25T00:00:00Z","page":"380","citation":{"ista":"Cipolloni G. 2021.

As scheduling non-determinism creates exponentially large spaces of thread interleavings, SMC attempts to partition this space into equivalence classes and explore only a few representatives from each class. The efficiency of this approach depends on two factors: (a) the coarseness of the partitioning, and (b) the time to generate representatives in each class. For this reason, the search for coarse partitionings that are efficiently explorable is an active research challenge. In this work we present RVF-SMC , a new SMC algorithm that uses a novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are deemed equivalent if they agree on the value obtained in each read event, and read events induce consistent causal orderings between them. The RVF partitioning is provably coarser than recent approaches based on Mazurkiewicz and “reads-from” partitionings. Our experimental evaluation reveals that RVF is quite often a very effective equivalence, as the underlying partitioning is exponentially coarser than other approaches. Moreover, RVF-SMC generates representatives very efficiently, as the reduction in the partitioning is often met with significant speed-ups in the model checking task."}],"_id":"9987","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","status":"public","title":"Stateless model checking under a reads-value-from equivalence","ddc":["000"],"file":[{"creator":"dernst","content_type":"application/pdf","file_size":1516756,"file_name":"2021_LNCS_Agarwal.pdf","access_level":"open_access","date_created":"2022-05-13T07:00:20Z","date_updated":"2022-05-13T07:00:20Z","success":1,"checksum":"4b346e5fbaa8b9bdf107819c7b2aadee","file_id":"11368","relation":"main_file"}],"oa_version":"Published Version","publication_identifier":{"isbn":["978-3-030-81684-1"],"eissn":["1611-3349"],"eisbn":["978-3-030-81685-8"],"issn":["0302-9743"]},"month":"07","external_id":{"arxiv":["2105.06424"],"isi":["000698732400016"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"project":[{"_id":"25892FC0-B435-11E9-9278-68D0E5697425","grant_number":"ICT15-003","name":"Efficient Algorithms for Computer Aided Verification"},{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"}],"quality_controlled":"1","isi":1,"doi":"10.1007/978-3-030-81685-8_16","conference":{"name":"CAV: Computer Aided Verification ","location":"Virtual","start_date":"2021-07-20","end_date":"2021-07-23"},"language":[{"iso":"eng"}],"ec_funded":1,"file_date_updated":"2022-05-13T07:00:20Z","acknowledgement":"The research was partially funded by the ERC CoG 863818 (ForM-SMArt) and the Vienna Science and Technology Fund (WWTF) through project ICT15-003.","year":"2021","department":[{"_id":"KrCh"}],"publisher":"Springer Nature","publication_status":"published","related_material":{"record":[{"id":"10199","status":"public","relation":"dissertation_contains"}]},"author":[{"last_name":"Agarwal","first_name":"Pratyush","full_name":"Agarwal, Pratyush"},{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee"},{"full_name":"Pathak, Shreya","first_name":"Shreya","last_name":"Pathak"},{"last_name":"Pavlogiannis","first_name":"Andreas","orcid":"0000-0002-8943-0722","id":"49704004-F248-11E8-B48F-1D18A9856A87","full_name":"Pavlogiannis, Andreas"},{"orcid":"0000-0001-9036-063X","id":"3AF3DA7C-F248-11E8-B48F-1D18A9856A87","last_name":"Toman","first_name":"Viktor","full_name":"Toman, Viktor"}],"volume":"12759 ","date_created":"2021-09-05T22:01:24Z","date_updated":"2023-09-07T13:30:27Z"},{"title":"Curvature driven interface evolution: Uniqueness properties of weak solution concepts","ddc":["515"],"status":"public","_id":"10007","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file":[{"relation":"source_file","file_id":"10008","checksum":"c8475faaf0b680b4971f638f1db16347","date_updated":"2021-09-15T14:37:30Z","date_created":"2021-09-13T11:03:24Z","access_level":"closed","file_name":"thesis_final_Hensel.zip","file_size":15022154,"content_type":"application/x-zip-compressed","creator":"shensel"},{"date_updated":"2021-09-14T09:52:47Z","date_created":"2021-09-13T14:18:56Z","checksum":"1a609937aa5275452822f45f2da17f07","relation":"main_file","file_id":"10014","content_type":"application/pdf","file_size":6583638,"creator":"shensel","file_name":"thesis_final_Hensel.pdf","access_level":"open_access"}],"oa_version":"Published Version","alternative_title":["ISTA Thesis"],"type":"dissertation","abstract":[{"lang":"eng","text":"The present thesis is concerned with the derivation of weak-strong uniqueness principles for curvature driven interface evolution problems not satisfying a comparison principle. The specific examples being treated are two-phase Navier-Stokes flow with surface tension, modeling the evolution of two incompressible, viscous and immiscible fluids separated by a sharp interface, and multiphase mean curvature flow, which serves as an idealized model for the motion of grain boundaries in an annealing polycrystalline material. Our main results - obtained in joint works with Julian Fischer, Tim Laux and Theresa M. Simon - state that prior to the formation of geometric singularities due to topology changes, the weak solution concept of Abels (Interfaces Free Bound. 9, 2007) to two-phase Navier-Stokes flow with surface tension and the weak solution concept of Laux and Otto (Calc. Var. Partial Differential Equations 55, 2016) to multiphase mean curvature flow (for networks in R^2 or double bubbles in R^3) represents the unique solution to these interface evolution problems within the class of classical solutions, respectively. To the best of the author's knowledge, for interface evolution problems not admitting a geometric comparison principle the derivation of a weak-strong uniqueness principle represented an open problem, so that the works contained in the present thesis constitute the first positive results in this direction. The key ingredient of our approach consists of the introduction of a novel concept of relative entropies for a class of curvature driven interface evolution problems, for which the associated energy contains an interfacial contribution being proportional to the surface area of the evolving (network of) interface(s). The interfacial part of the relative entropy gives sufficient control on the interface error between a weak and a classical solution, and its time evolution can be computed, at least in principle, for any energy dissipating weak solution concept. A resulting stability estimate for the relative entropy essentially entails the above mentioned weak-strong uniqueness principles. The present thesis contains a detailed introduction to our relative entropy approach, which in particular highlights potential applications to other problems in curvature driven interface evolution not treated in this thesis."}],"page":"300","citation":{"chicago":"Hensel, Sebastian. “Curvature Driven Interface Evolution: Uniqueness Properties of Weak Solution Concepts.” Institute of Science and Technology Austria, 2021. https://doi.org/10.15479/at:ista:10007.","mla":"Hensel, Sebastian.

For an execution of n events over k threads and d variables, we establish novel bounds that scale as nk+1 for TSO and as nk+1· min(nk2, 2k· d) for PSO. Moreover, based on our solution to these problems, we develop an SMC algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal, in the sense that it is guaranteed to explore each class of the RF partitioning exactly once, and spends polynomial time per class when k is bounded. Finally, we implement all our algorithms in the SMC tool Nidhugg, and perform a large number of experiments over benchmarks from existing literature. Our experimental results show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO, which yields a significant speedup in the model checking task.\r\n\r\n","lang":"eng"}],"intvolume":" 5","status":"public","title":"The reads-from equivalence for the TSO and PSO memory models","ddc":["000"],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","_id":"10191","oa_version":"Published Version","file":[{"creator":"cchlebak","content_type":"application/pdf","file_size":2903485,"access_level":"open_access","file_name":"2021_ProcACMPL_Bui.pdf","success":1,"checksum":"9d6dce7b611853c529bb7b1915ac579e","date_created":"2021-11-04T07:24:48Z","date_updated":"2021-11-04T07:24:48Z","file_id":"10215","relation":"main_file"}],"keyword":["safety","risk","reliability and quality","software"],"scopus_import":"1","article_processing_charge":"No","has_accepted_license":"1","day":"15","article_type":"original","citation":{"chicago":"Bui, Truc Lam, Krishnendu Chatterjee, Tushar Gautam, Andreas Pavlogiannis, and Viktor Toman. “The Reads-from Equivalence for the TSO and PSO Memory Models.” Proceedings of the ACM on Programming Languages.

In one, the inductor is replaced by a nonlinear Josephson junction to realize the widely used charge qubits with a compact phase variable and a discrete charge wave function. In the other, the junction is added in parallel, which gives rise to an extended phase variable, continuous wave functions, and a rich energy-level structure due to the loop topology. While the corresponding rf superconducting quantum interference device Hamiltonian was introduced as a quadratic quasi-one-dimensional potential approximation to describe the fluxonium qubit implemented with long Josephson-junction arrays, in this work we implement it directly using a linear superinductor formed by a single uninterrupted aluminum wire. We present a large variety of qubits, all stemming from the same circuit but with drastically different characteristic energy scales. This includes flux and fluxonium qubits but also the recently introduced quasicharge qubit with strongly enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion.

More in detail, my research focuses on the study of transport costs on graphs, in particular the convergence and the stability of such problems in the discrete-to-continuum limit. This thesis also includes some results concerning\r\nnon-commutative optimal transport. The first chapter of this thesis consists of a general introduction to the optimal transport problems, both in the discrete, the continuous, and the non-commutative setting. Chapters 2 and 3 present the content of two works, obtained in collaboration with Peter Gladbach, Eva Kopfer, and Jan Maas, where we have been able to show the convergence of discrete transport costs on periodic graphs to suitable continuous ones, which can be described by means of a homogenisation result. We first focus on the particular case of quadratic costs on the real line and then extending the result to more general costs in arbitrary dimension. Our results are the first complete characterisation of limits of transport costs on periodic graphs in arbitrary dimension which do not rely on any additional symmetry. In Chapter 4 we turn our attention to one of the intriguing connection between evolution equations and optimal transport, represented by the theory of gradient flows. We show that discrete gradient flow structures associated to a finite volume approximation of a certain class of diffusive equations (Fokker–Planck) is stable in the limit of vanishing meshes, reproving the convergence of the scheme via the method of evolutionary Γ-convergence and exploiting a more variational point of view on the problem. This is based on a collaboration with Dominik Forkert and Jan Maas. Chapter 5 represents a change of perspective, moving away from the discrete world and reaching the non-commutative one. As in the discrete case, we discuss how classical tools coming from the commutative optimal transport can be translated into the setting of density matrices. In particular, in this final chapter we present a non-commutative version of the Schrödinger problem (or entropic regularised optimal transport problem) and discuss existence and characterisation of minimisers, a duality result, and present a non-commutative version of the well-known Sinkhorn algorithm to compute the above mentioned optimisers. This is based on a joint work with Dario Feliciangeli and Augusto Gerolin. Finally, Appendix A and B contain some additional material and discussions, with particular attention to Harnack inequalities and the regularity of flows on discrete spaces."}],"type":"dissertation","alternative_title":["ISTA Thesis"],"oa_version":"Published Version","file":[{"file_name":"tex_and_pictures.zip","access_level":"closed","content_type":"application/x-zip-compressed","file_size":3876668,"creator":"cchlebak","relation":"source_file","file_id":"10032","date_updated":"2022-03-10T12:14:42Z","date_created":"2021-09-21T09:17:34Z","checksum":"8cd60dcb8762e8f21867e21e8001e183"},{"creator":"cchlebak","file_size":2532673,"content_type":"application/pdf","access_level":"open_access","file_name":"thesis_portinale_Final (1).pdf","checksum":"9789e9d967c853c1503ec7f307170279","date_updated":"2021-09-27T11:14:31Z","date_created":"2021-09-27T11:14:31Z","file_id":"10047","relation":"main_file"}],"_id":"10030","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"Discrete-to-continuum limits of transport problems and gradient flows in the space of measures","ddc":["515"],"status":"public"},{"month":"08","publication_identifier":{"isbn":["978-3-99078-013-8"],"issn":["2663-337X"]},"doi":"10.15479/at:ista:9920","acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"degree_awarded":"PhD","supervisor":[{"full_name":"Fink, Johannes M","first_name":"Johannes M","last_name":"Fink","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X"}],"language":[{"iso":"eng"}],"oa":1,"file_date_updated":"2021-09-06T08:39:47Z","author":[{"full_name":"Peruzzo, Matilda","first_name":"Matilda","last_name":"Peruzzo","id":"3F920B30-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3415-4628"}],"related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"9928"},{"id":"8755","status":"public","relation":"part_of_dissertation"}]},"date_created":"2021-08-16T09:44:09Z","date_updated":"2023-09-07T13:31:22Z","year":"2021","publication_status":"published","publisher":"Institute of Science and Technology Austria","department":[{"_id":"GradSch"},{"_id":"JoFi"}],"day":"19","has_accepted_license":"1","article_processing_charge":"No","keyword":["quantum computing","superinductor","quantum metrology"],"date_published":"2021-08-19T00:00:00Z","citation":{"apa":"Peruzzo, M.

The Josephson junction has revolutionized the field of superconducting circuits as a non-linear dissipation-less circuit element and is used in almost all superconducting qubit implementations since the 90s. On the other hand, the superinductor is a relatively new circuit element introduced as a key component of the fluxonium qubit in 2009. This is an inductor with characteristic impedance larger than the resistance quantum and self-resonance frequency in the GHz regime. The combination of these two elements can occur in two fundamental ways: in parallel and in series. When connected in parallel the two create the fluxonium qubit, a loop with large inductance and a rich energy spectrum reliant on quantum tunneling. On the other hand placing the two elements in series aids with the measurement of the IV curve of a single Josephson junction in a high impedance environment. In this limit theory predicts that the junction will behave as its dual element: the phase-slip junction. While the Josephson junction acts as a non-linear inductor the phase-slip junction has the behavior of a non-linear capacitance and can be used to measure new Josephson junction phenomena, namely Coulomb blockade of Cooper pairs and phase-locked Bloch oscillations. The latter experiment allows for a direct link between frequency and current which is an elusive connection in quantum metrology. This work introduces the geometric superinductor, a superconducting circuit element where the high inductance is due to the geometry rather than the material properties of the superconductor, realized from a highly miniaturized superconducting planar coil. These structures will be described and characterized as resonators and qubit inductors and progress towards the measurement of phase-locked Bloch oscillations will be presented.","lang":"eng"}],"type":"dissertation","alternative_title":["ISTA Thesis"],"oa_version":"Published Version","file":[{"checksum":"3cd1986efde5121d7581f6fcf9090da8","date_created":"2021-08-16T09:33:21Z","date_updated":"2021-09-06T08:39:47Z","relation":"source_file","file_id":"9924","content_type":"application/x-zip-compressed","file_size":151387283,"creator":"mperuzzo","access_level":"closed","file_name":"GeometricSuperinductorsForCQED.zip"},{"access_level":"open_access","file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-1b.pdf","creator":"mperuzzo","file_size":17596344,"content_type":"application/pdf","file_id":"9939","relation":"main_file","checksum":"50928c621cdf0775d7a5906b9dc8602c","date_updated":"2021-09-06T08:39:47Z","date_created":"2021-08-18T14:20:06Z"},{"creator":"mperuzzo","file_size":17592425,"content_type":"application/pdf","access_level":"closed","description":"Extra copy of the thesis as PDF/A-2b","file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-2b.pdf","checksum":"37f486aa1b622fe44af00d627ec13f6c","date_updated":"2021-09-06T08:39:47Z","date_created":"2021-08-18T14:20:09Z","file_id":"9940","relation":"other"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"9920","status":"public","ddc":["539"],"title":"Geometric superinductors and their applications in circuit quantum electrodynamics"},{"ec_funded":1,"related_material":{"record":[{"id":"10429","relation":"dissertation_contains","status":"public"}]},"author":[{"full_name":"Nadiradze, Giorgi","orcid":"0000-0001-5634-0731","id":"3279A00C-F248-11E8-B48F-1D18A9856A87","last_name":"Nadiradze","first_name":"Giorgi"},{"full_name":"Markov, Ilia","last_name":"Markov","first_name":"Ilia","id":"D0CF4148-C985-11E9-8066-0BDEE5697425"},{"first_name":"Bapi","last_name":"Chatterjee","id":"3C41A08A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2742-4028","full_name":"Chatterjee, Bapi"},{"first_name":"Vyacheslav ","last_name":"Kungurtsev","full_name":"Kungurtsev, Vyacheslav "},{"first_name":"Dan-Adrian","last_name":"Alistarh","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3650-940X","full_name":"Alistarh, Dan-Adrian"}],"volume":35,"date_created":"2021-12-09T09:21:35Z","date_updated":"2023-09-07T13:31:39Z","acknowledgement":"We would like to thank Christopher De Sa for his feedback on an earlier draft of this paper, as well as the anonymous AAAI reviewers for their useful comments.

Most of these models are trained employing variants of stochastic gradient descent (SGD) based optimization, but most methods involve some type of consistency relaxation relative to sequential SGD, to mitigate its large communication or synchronization costs at scale. In this paper, we introduce a general consistency condition covering communication-reduced and asynchronous distributed SGD implementations. Our framework, called elastic consistency, decouples the system-specific aspects of the implementation from the SGD convergence requirements, giving a general way to obtain convergence bounds for a wide variety of distributed SGD methods used in practice. Elastic consistency can be used to re-derive or improve several previous convergence bounds in message-passing and shared-memory settings, but also to analyze new models and distribution schemes. As a direct application, we propose and analyze a new synchronization-avoiding scheduling scheme for distributed SGD, and show that it can be used to efficiently train deep convolutional models for image classification.","lang":"eng"}],"type":"conference","oa_version":"Published Version","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","_id":"10432","intvolume":" 35","title":"Elastic consistency: A practical consistency model for distributed stochastic gradient descent","status":"public","article_processing_charge":"No","day":"18","date_published":"2021-05-18T00:00:00Z","citation":{"chicago":"Nadiradze, Giorgi, Ilia Markov, Bapi Chatterjee, Vyacheslav Kungurtsev, and Dan-Adrian Alistarh. “Elastic Consistency: A Practical Consistency Model for Distributed Stochastic Gradient Descent.” In Proceedings of the AAAI Conference on Artificial Intelligence, 35:9037–45, 2021.","mla":"Nadiradze, Giorgi, et al. “Elastic Consistency: A Practical Consistency Model for Distributed Stochastic Gradient Descent.” Proceedings of the AAAI Conference on Artificial Intelligence, vol. 35, no. 10, 2021, pp. 9037–45.","short":"G.

Lindell and Pinkas (Journal of Cryptograhy 2009) gave a formal proof of security in the selective setting where the adversary chooses the challenge inputs before seeing the garbled circuit assuming secure symmetric-key encryption (and hence one-way functions). This was followed by results, both positive and negative, concerning its security in the, stronger, adaptive setting. Applebaum et al. (Crypto 2013) showed that it cannot satisfy adaptive security as is, due to a simple incompressibility argument. Jafargholi and Wichs (TCC 2017) considered a natural adaptation of Yao’s scheme (where the output mapping is sent in the online phase, together with the garbled input) that circumvents this negative result, and proved that it is adaptively secure, at least for shallow circuits. In particular, they showed that for the class of circuits of depth δ , the loss in security is at most exponential in δ . The above results all concern the simulation-based notion of security. In this work, we show that the upper bound of Jafargholi and Wichs is basically optimal in a strong sense. As our main result, we show that there exists a family of Boolean circuits, one for each depth δ∈N , such that any black-box reduction proving the adaptive indistinguishability of the natural adaptation of Yao’s scheme from any symmetric-key encryption has to lose a factor that is exponential in δ√ . Since indistinguishability is a weaker notion than simulation, our bound also applies to adaptive simulation. To establish our results, we build on the recent approach of Kamath et al. (Eprint 2021), which uses pebbling lower bounds in conjunction with oracle separations to prove fine-grained lower bounds on loss in cryptographic security.","lang":"eng"}]},{"oa":1,"main_file_link":[{"url":"https://eprint.iacr.org/2019/1489","open_access":"1"}],"project":[{"call_identifier":"H2020","name":"International IST Doctoral Program","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"},{"name":"Teaching Old Crypto New Tricks","call_identifier":"H2020","_id":"258AA5B2-B435-11E9-9278-68D0E5697425","grant_number":"682815"}],"quality_controlled":"1","doi":"10.1109/sp40001.2021.00035","conference":{"name":"SP: Symposium on Security and Privacy","location":"San Francisco, CA, United States","start_date":"2021-05-24","end_date":"2021-05-27"},"language":[{"iso":"eng"}],"month":"08","acknowledgement":"The first three authors contributed equally to this work.

The two existing proposals to date are ART (Cohn-Gordon et al., CCS18) and TreeKEM (IETF, The Messaging Layer Security Protocol, draft). TreeKEM is the currently considered candidate by the IETF MLS working group, but dynamic group operations (i.e. adding and removing users) can cause efficiency issues. In this paper we formalize and analyze a variant of TreeKEM which we term Tainted TreeKEM (TTKEM for short). The basic idea underlying TTKEM was suggested by Millican (MLS mailing list, February 2018). This version is more efficient than TreeKEM for some natural distributions of group operations, we quantify this through simulations.Our second contribution is two security proofs for TTKEM which establish post compromise and forward secrecy even against adaptive attackers. The security loss (to the underlying PKE) in the Random Oracle Model is a polynomial factor, and a quasipolynomial one in the Standard Model. Our proofs can be adapted to TreeKEM as well. Before our work no security proof for any TreeKEM-like protocol establishing tight security against an adversary who can adaptively choose the sequence of operations was known. We also are the first to prove (or even formalize) active security where the server can arbitrarily deviate from the protocol specification. Proving fully active security – where also the users can arbitrarily deviate – remains open."}]},{"quality_controlled":"1","project":[{"name":"Teaching Old Crypto New Tricks","call_identifier":"H2020","grant_number":"682815","_id":"258AA5B2-B435-11E9-9278-68D0E5697425"}],"publication":"19th Theory of Cryptography Conference 2021","citation":{"ama":"Kamath Hosdurg C, Klein K, Pietrzak KZ.
