Our algorithm works under the relaxed setting where each machine is allowed to perform exponential local computations, while respecting the n^φ space and bandwidth limitations.\r\n\r\nOur key technical contribution is a novel derandomization of the ingenious (Δ+1)-coloring local algorithm by Chang-Li-Pettie (STOC 2018, SIAM J. Comput. 2020). The Chang-Li-Pettie algorithm runs in T_local =poly(loglog n) rounds, which sets the state-of-the-art randomized round complexity for the problem in the local model. 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. Furthermore, no deterministic sublogarithmic low-space MPC algorithms for the (Δ+1)-coloring problem have been known before.","lang":"eng"}],"oa_version":"Submitted Version","ec_funded":1,"publication_status":"published","publication_identifier":{"isbn":["978-1-4503-8548-0"]},"language":[{"iso":"eng"}]},{"citation":{"ieee":"G.

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."}],"month":"07","main_file_link":[{"url":"https://arxiv.org/abs/2106.01880","open_access":"1"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Czumaj, Artur, et al. “Component Stability in Low-Space Massively Parallel Computation.” Proceedings of the 2021 ACM Symposium on Principles of Distributed Computing, Association for Computing Machinery, 2021, pp. 481–491, doi:10.1145/3465084.3467903.","ieee":"A.

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. Our models are publicly available and can be readily used as input for detailed supernova simulations."}],"oa_version":"Published Version","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.1051/0004-6361/202140506","open_access":"1"}],"month":"12","intvolume":" 656","date_updated":"2023-08-21T11:49:15Z","_id":"13455","type":"journal_article","article_type":"original","status":"public","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"year":"2021","day":"02","publication":"Astronomy & Astrophysics","doi":"10.1051/0004-6361/202140506","date_published":"2021-12-02T00:00:00Z","date_created":"2023-08-03T10:11:09Z","publisher":"EDP Sciences","quality_controlled":"1","oa":1,"citation":{"mla":"Laplace, E., et al. “Different to the Core: The Pre-Supernova Structures of Massive Single and Binary-Stripped Stars.” Astronomy & Astrophysics, vol. 656, A58, EDP Sciences, 2021, doi:10.1051/0004-6361/202140506.","ama":"Laplace E, Justham S, Renzo M, et al.

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"}],"volume":126,"issue":"4","ec_funded":1,"file":[{"access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"9074","checksum":"d9acbc502390ed7a97e631d23ae19ecd","success":1,"creator":"dernst","date_updated":"2021-02-03T12:47:04Z","file_size":398075,"date_created":"2021-02-03T12:47:04Z","file_name":"2021_PhysicalRevLett_DeNicola.pdf"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"publication_status":"published","status":"public","keyword":["General Physics and Astronomy"],"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)"},"_id":"9048","file_date_updated":"2021-02-03T12:47:04Z","department":[{"_id":"MaSe"}],"ddc":["530"],"date_updated":"2023-09-05T12:08:58Z","quality_controlled":"1","publisher":"American Physical Society","oa":1,"acknowledgement":"S.

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.

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."}],"pmid":1,"oa_version":"Published Version","ec_funded":1,"issue":"9","volume":31,"publication_status":"published","publication_identifier":{"issn":["0960-9822"],"eissn":["1879-0445"]},"language":[{"iso":"eng"}],"file":[{"creator":"dernst","file_size":4324371,"date_updated":"2021-04-01T10:53:42Z","file_name":"2021_CurrentBiology_Glanc.pdf","date_created":"2021-04-01T10:53:42Z","relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"checksum":"b1723040ecfd8c81194185472eb62546","file_id":"9303"}],"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)"},"type":"journal_article","article_type":"original","status":"public","_id":"9290","department":[{"_id":"JiFr"}],"file_date_updated":"2021-04-01T10:53:42Z","date_updated":"2023-09-05T13:03:34Z","ddc":["580"]},{"external_id":{"pmid":["33157019"],"isi":["000614361000039"]},"article_processing_charge":"Yes (via OA deal)","author":[{"full_name":"Marquès-Bueno, MM","last_name":"Marquès-Bueno","first_name":"MM"},{"last_name":"Armengot","full_name":"Armengot, L","first_name":"L"},{"first_name":"LC","full_name":"Noack, LC","last_name":"Noack"},{"first_name":"J","last_name":"Bareille","full_name":"Bareille, J"},{"last_name":"Rodriguez Solovey","full_name":"Rodriguez Solovey, Lesia","orcid":"0000-0002-7244-7237","id":"3922B506-F248-11E8-B48F-1D18A9856A87","first_name":"Lesia"},{"full_name":"Platre, MP","last_name":"Platre","first_name":"MP"},{"last_name":"Bayle","full_name":"Bayle, V","first_name":"V"},{"last_name":"Liu","full_name":"Liu, M","first_name":"M"},{"first_name":"D","last_name":"Opdenacker","full_name":"Opdenacker, D"},{"last_name":"Vanneste","full_name":"Vanneste, S","first_name":"S"},{"last_name":"Möller","full_name":"Möller, BK","first_name":"BK"},{"first_name":"ZL","last_name":"Nimchuk","full_name":"Nimchuk, ZL"},{"last_name":"Beeckman","full_name":"Beeckman, T","first_name":"T"},{"first_name":"AI","full_name":"Caño-Delgado, AI","last_name":"Caño-Delgado"},{"first_name":"Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596","full_name":"Friml, Jiří","last_name":"Friml"},{"full_name":"Jaillais, Y","last_name":"Jaillais","first_name":"Y"}],"title":"Auxin-regulated reversible inhibition of TMK1 signaling by MAKR2 modulates the dynamics of root gravitropism","citation":{"ista":"Marquès-Bueno M, Armengot L, Noack L, Bareille J, Rodriguez Solovey L, Platre M, Bayle V, Liu M, Opdenacker D, Vanneste S, Möller B, Nimchuk Z, Beeckman T, Caño-Delgado A, Friml J, Jaillais Y. 2021.

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."}],"oa_version":"Published Version","pmid":1},{"oa_version":"Preprint","abstract":[{"lang":"eng","text":"Electrodepositing insulating lithium peroxide (Li2O2) is the key process during discharge of aprotic Li–O2 batteries and determines rate, capacity, and reversibility. 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."}],"acknowledged_ssus":[{"_id":"EM-Fac"}],"intvolume":" 118","month":"04","main_file_link":[{"url":"https://doi.org/10.26434/chemrxiv.11447775","open_access":"1"}],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"volume":118,"issue":"14","_id":"9301","keyword":["small-angle X-ray scattering","oxygen reduction","disproportionation","Li-air battery"],"status":"public","article_type":"original","type":"journal_article","date_updated":"2023-09-05T13:27:18Z","department":[{"_id":"StFr"},{"_id":"EM-Fac"}],"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."}],"oa_version":"None","intvolume":" 168","month":"05","date_updated":"2023-09-05T13:25:30Z","department":[{"_id":"StFr"}],"_id":"9447","type":"journal_article","keyword":["Renewable Energy","Sustainability and the Environment","Electrochemistry","Materials Chemistry","Electronic","Optical and Magnetic Materials","Surfaces","Coatings and Films","Condensed Matter Physics"],"status":"public","year":"2021","isi":1,"publication":"Journal of The Electrochemical Society","day":"01","date_created":"2021-06-03T09:58:38Z","doi":"10.1149/1945-7111/ac0300","date_published":"2021-05-01T00:00:00Z","publisher":"IOP Publishing","quality_controlled":"1","citation":{"ista":"Maffre M, Bouchal R, Freunberger SA, Lindahl N, Johansson P, Favier F, Fontaine O, Bélanger D. 2021.

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."}],"volume":220,"issue":"4","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","file":[{"file_id":"11367","checksum":"843ebc153847c8626e13c9c5ce71d533","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_created":"2022-05-12T14:16:21Z","file_name":"2021_JournCellBiology_Leithner.pdf","date_updated":"2022-05-12T14:16:21Z","file_size":5102328,"creator":"dernst"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0021-9525"],"eissn":["1540-8140"]},"publication_status":"published","article_number":"e202006081","title":"Dendritic cell actin dynamics control contact duration and priming efficiency at the immunological synapse","author":[{"last_name":"Leithner","full_name":"Leithner, Alexander F","orcid":"0000-0002-1073-744X","id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","first_name":"Alexander F"},{"first_name":"LM","last_name":"Altenburger","full_name":"Altenburger, LM"},{"first_name":"R","full_name":"Hauschild, R","last_name":"Hauschild"},{"orcid":"0000-0003-3470-6119","full_name":"Assen, Frank P","last_name":"Assen","first_name":"Frank P","id":"3A8E7F24-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Rottner, K","last_name":"Rottner","first_name":"K"},{"first_name":"Stradal","full_name":"TEB, Stradal","last_name":"TEB"},{"first_name":"A","last_name":"Diz-Muñoz","full_name":"Diz-Muñoz, A"},{"first_name":"JV","full_name":"Stein, JV","last_name":"Stein"},{"full_name":"Sixt, Michael K","orcid":"0000-0002-6620-9179","last_name":"Sixt","first_name":"Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","external_id":{"isi":["000626365700001"],"pmid":["33533935"]},"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"short":"A.F.

One approach to determining how interactions between these circuit components give rise to complex behavior is to investigate the rules by which cortical circuits are formed and acquire functionality during development. This review summarizes recent research on the development of the neocortex, from genetic determination in neural stem cells through to the dynamic role that specific neuronal populations play in the earliest circuits of neocortex, and how they contribute to emergent function and cognition. 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. Such cross-species perspective is imperative when investigating the mechanisms underlying the dysfunction of early neocortical circuits in neurodevelopmental disorders, so that one can identify targets amenable to therapeutic intervention."}],"volume":41,"issue":"5","ec_funded":1,"file":[{"content_type":"application/pdf","relation":"main_file","access_level":"open_access","success":1,"checksum":"578fd7ed1a0aef74bce61bea2d987b33","file_id":"11414","file_size":1031150,"date_updated":"2022-05-27T06:59:55Z","creator":"dernst","file_name":"2021_JourNeuroscience_Hanganu.pdf","date_created":"2022-05-27T06:59:55Z"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1529-2401"],"issn":["0270-6474"]},"publication_status":"published","status":"public","keyword":["General Neuroscience"],"article_type":"original","type":"journal_article","_id":"9073","file_date_updated":"2022-05-27T06:59:55Z","department":[{"_id":"SiHi"}],"ddc":["570"],"date_updated":"2023-09-05T14:03:17Z"},{"department":[{"_id":"MaMo"}],"file_date_updated":"2021-12-13T15:47:54Z","ddc":["510"],"date_updated":"2023-09-05T14:13:57Z","keyword":["Applied Mathematics","Computational Theory and Mathematics","Computational Mathematics","Analysis"],"status":"public","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","_id":"10211","language":[{"iso":"eng"}],"file":[{"success":1,"file_id":"10542","checksum":"9ea12dd8045a0678000a3a59295221cb","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"2021_Springer_Mondelli.pdf","date_created":"2021-12-13T15:47:54Z","file_size":2305731,"date_updated":"2021-12-13T15:47:54Z","creator":"alisjak"}],"publication_status":"published","publication_identifier":{"issn":["1615-3375"],"eissn":["1615-3383"]},"month":"08","scopus_import":"1","oa_version":"Published Version","abstract":[{"lang":"eng","text":"We study the problem of recovering an unknown signal 𝑥𝑥 given measurements obtained from a generalized linear model with a Gaussian sensing matrix. 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."}],"title":"Optimal combination of linear and spectral estimators for generalized linear models","article_processing_charge":"Yes (via OA deal)","external_id":{"arxiv":["2008.03326"],"isi":["000685721000001"]},"author":[{"id":"27EB676C-8706-11E9-9510-7717E6697425","first_name":"Marco","last_name":"Mondelli","full_name":"Mondelli, Marco","orcid":"0000-0002-3242-7020"},{"full_name":"Thrampoulidis, Christos","last_name":"Thrampoulidis","first_name":"Christos"},{"full_name":"Venkataramanan, Ramji","last_name":"Venkataramanan","first_name":"Ramji"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"ista":"Mondelli M, Thrampoulidis C, Venkataramanan R. 2021.
