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"}],"issue":"26","volume":184,"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eissn":["1097-4172"],"issn":["0092-8674"]}},{"department":[{"_id":"ToHe"}],"file_date_updated":"2022-01-26T08:04:50Z","date_updated":"2023-08-17T06:56:42Z","ddc":["510"],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","keyword":["computer science","computer science and game theory","logic in computer science"],"status":"public","_id":"10674","license":"https://creativecommons.org/licenses/by/4.0/","volume":17,"issue":"1","publication_status":"published","publication_identifier":{"eissn":["1860-5974"]},"language":[{"iso":"eng"}],"file":[{"checksum":"b35586a50ed1ca8f44767de116d18d81","file_id":"10690","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_created":"2022-01-26T08:04:50Z","file_name":"2021_LMCS_AGHAJOHAR.pdf","date_updated":"2022-01-26T08:04:50Z","file_size":819878,"creator":"alisjak"}],"scopus_import":"1","intvolume":" 17","month":"02","abstract":[{"text":"In two-player games on graphs, the players move a token through a graph to produce an infinite path, which determines the winner of the game. 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.","lang":"eng"}],"oa_version":"Published Version","external_id":{"arxiv":["1905.03588"],"isi":["000658724600010"]},"article_processing_charge":"No","author":[{"last_name":"Aghajohari","full_name":"Aghajohari, Milad","first_name":"Milad"},{"id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","first_name":"Guy","last_name":"Avni","full_name":"Avni, Guy","orcid":"0000-0001-5588-8287"},{"orcid":"0000-0002-2985-7724","full_name":"Henzinger, Thomas A","last_name":"Henzinger","first_name":"Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87"}],"title":"Determinacy in discrete-bidding infinite-duration games","citation":{"ama":"Aghajohari M, Avni G, Henzinger TA.

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."}],"intvolume":" 13091","month":"12","main_file_link":[{"open_access":"1","url":"https://eprint.iacr.org/2021/1262"}],"scopus_import":"1","alternative_title":["LNCS"],"date_updated":"2023-08-17T06:34:41Z","department":[{"_id":"KrPi"}],"_id":"10609","status":"public","conference":{"start_date":"2021-12-06","end_date":"2021-12-10","location":"Virtual, Singapore","name":"ASIACRYPT: International Conference on Cryptology in Asia"},"type":"conference","publication":"27th International Conference on the Theory and Application of Cryptology and Information Security","day":"01","year":"2021","isi":1,"date_created":"2022-01-09T23:01:27Z","doi":"10.1007/978-3-030-92075-3_12","date_published":"2021-12-01T00:00:00Z","page":"335-364","oa":1,"quality_controlled":"1","publisher":"Springer Nature","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ama":"Chakraborty S, Ganesh C, Pancholi M, Sarkar P.

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"}],"oa_version":"Published Version","volume":10,"publication_identifier":{"eissn":["2050-084X"]},"publication_status":"published","file":[{"success":1,"checksum":"759c7a873d554c48a6639e6350746ca6","file_id":"10611","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"2021_eLife_Godard.pdf","date_created":"2022-01-10T09:40:37Z","creator":"alisjak","file_size":7769934,"date_updated":"2022-01-10T09:40:37Z"}],"language":[{"iso":"eng"}],"type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","_id":"10606","department":[{"_id":"CaHe"}],"file_date_updated":"2022-01-10T09:40:37Z","date_updated":"2023-08-17T06:32:44Z","ddc":["570"]},{"scopus_import":"1","intvolume":" 91","month":"10","abstract":[{"lang":"eng","text":"The evidence linking innate immunity mechanisms and neurodegenerative diseases is growing, but the specific mechanisms are incompletely understood.

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.

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.","lang":"eng"}],"month":"12","intvolume":" 23","scopus_import":"1","file":[{"creator":"cchlebak","date_updated":"2022-01-17T10:01:58Z","file_size":2533102,"date_created":"2022-01-17T10:01:58Z","file_name":"2021_NewJourPhys_Ghazaryan.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","checksum":"0c3cb6816242fa8afd1cc87a5fe77821","file_id":"10632","success":1}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["1367-2630"]},"publication_status":"published","issue":"12","volume":23,"ec_funded":1},{"doi":"10.1103/PhysRevA.104.L061303","date_published":"2021-12-30T00:00:00Z","date_created":"2022-01-16T23:01:29Z","isi":1,"year":"2021","day":"30","publication":"Physical Review A","publisher":"American Physical Society","quality_controlled":"1","oa":1,"acknowledgement":"I.C. acknowledges the support by the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie Grant Agreement No. 665385.

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. Our results suggest that adversarial training is not yet ready for robot learning.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2103.08187"}],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["1050-4729"],"isbn":["978-1-7281-9078-5"],"eissn":["2577-087X"],"eisbn":["978-1-7281-9077-8"]},"license":"https://creativecommons.org/licenses/by-nc-nd/3.0/","related_material":{"record":[{"status":"public","id":"11362","relation":"dissertation_contains"}]},"_id":"10666","series_title":"ICRA","status":"public","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/3.0/legalcode","short":"CC BY-NC-ND (3.0)"},"conference":{"name":"ICRA: International Conference on Robotics and Automation","start_date":"2021-05-30","end_date":"2021-06-05","location":"Xi'an, China"},"type":"conference","ddc":["000"],"date_updated":"2023-08-17T06:58:38Z","department":[{"_id":"GradSch"},{"_id":"ToHe"}]},{"keyword":["Algebra and Number Theory"],"status":"public","article_type":"original","type":"journal_article","_id":"10711","department":[{"_id":"TiBr"}],"date_updated":"2023-08-17T06:59:16Z","intvolume":" 157","month":"06","main_file_link":[{"url":"https://arxiv.org/abs/1909.03266","open_access":"1"}],"oa_version":"Preprint","abstract":[{"text":"In this paper, we investigate the distribution of the maximum of partial sums of families of m -periodic complex-valued functions satisfying certain conditions.

In this direction, thermoelectric materials that do not rely on rare or toxic elements such as tellurium or lead need to be produced using high-throughput technologies not involving high temperatures and long processes. 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."}]},{"volume":31,"issue":"10","publication_status":"published","publication_identifier":{"issn":["0960-9822"]},"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1101/2020.03.24.005835"}],"scopus_import":"1","intvolume":" 31","month":"05","abstract":[{"text":"Hematopoietic-specific protein 1 (Hem1) is an essential subunit of the WAVE regulatory complex (WRC) in immune cells. 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.","lang":"eng"}],"oa_version":"Preprint","pmid":1,"department":[{"_id":"MiSi"}],"date_updated":"2023-08-17T07:01:14Z","article_type":"original","type":"journal_article","keyword":["General Agricultural and Biological Sciences","General Biochemistry","Genetics and Molecular Biology"],"status":"public","_id":"10834","page":"2051-2064.e8","date_created":"2022-03-08T07:51:04Z","doi":"10.1016/j.cub.2021.02.043","date_published":"2021-05-24T00:00:00Z","year":"2021","isi":1,"publication":"Current Biology","day":"24","oa":1,"quality_controlled":"1","publisher":"Elsevier","acknowledgement":"We are grateful to Silvia Prettin, Ina Schleicher, and Petra Hagendorff for expert technical assistance; David Dettbarn for animal keeping and breeding; and Lothar Gröbe and Maria Höxter for cell sorting.

Our derandomization employs a combination of tools, notably pseudorandom generators (PRG) and bounded-independence hash functions.\r\n\r\nThe achieved round complexity of O(logloglog n) rounds matches the bound of log(T_local ), which currently serves an upper bound barrier for all known randomized algorithms for locally-checkable problems in this model.

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.","lang":"eng"}],"oa_version":"Submitted Version","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2106.01880"}],"month":"07","publication_identifier":{"isbn":["9781450385480"]},"publication_status":"published","language":[{"iso":"eng"}],"ec_funded":1},{"citation":{"ieee":"D.

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"}],"oa_version":"Preprint","issue":"1","volume":916,"publication_status":"published","publication_identifier":{"eissn":["2041-8213"],"issn":["2041-8205"]},"language":[{"iso":"eng"}],"type":"journal_article","article_type":"original","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"status":"public","_id":"13458","date_updated":"2023-08-21T11:37:48Z","extern":"1"},{"publisher":"American Astronomical Society","quality_controlled":"1","oa":1,"year":"2021","day":"04","publication":"The Astronomical Journal","doi":"10.3847/1538-3881/abf144","date_published":"2021-05-04T00:00:00Z","date_created":"2023-08-03T10:11:57Z","article_number":"248","citation":{"ista":"Wang L, Gies DR, Peters GJ, Götberg YLL, Chojnowski SD, Lester KV, Howell SB. 2021.

Mass transfer will strip the donor star of its envelope to create a small and hot subdwarf remnant. Here we report on Hubble Space Telescope/STIS far-ultraviolet spectroscopy of a sample of Be stars that reveals the presence of the hot sdO companion through the calculation of cross-correlation functions of the observed and model spectra. We clearly detect the spectral signature of the sdO star in 10 of the 13 stars in the sample, and the spectral signals indicate that the sdO stars are hot, relatively faint, and slowly rotating as predicted by models. A comparison of their temperatures and radii with evolutionary tracks indicates that the sdO stars occupy the relatively long-lived, He-core burning stage. Only 1 of the 10 detections was a known binary prior to this investigation, which emphasizes the difficulty of finding such Be+sdO binaries through optical spectroscopy. However, these results and others indicate that many Be stars probably host hot subdwarf companions.","lang":"eng"}],"oa_version":"Preprint","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2103.13642"}],"month":"05","intvolume":" 161","publication_identifier":{"eissn":["1538-3881"],"issn":["0004-6256"]},"publication_status":"published","language":[{"iso":"eng"}],"issue":"5","volume":161,"_id":"13459","article_type":"original","type":"journal_article","status":"public","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"date_updated":"2023-08-21T11:35:50Z","extern":"1"}]
