Compared to other results in this direction, we do not need any smallness assumption on the transport noise which acts directly on the velocity field and we also allow rougher noise terms.

Here, we reveal a crossover between defect-free active turbulence and active turbulence laden with topological defects. Interestingly, we show that concurrent to the crossover from defect-free to defect-laden active turbulence is the restoration of the previously broken SO(2) symmetry signaled by the fast decay of the two-point correlations. By stability analyses of the topological charge density field, we provide theoretical insights on the criterion for the crossover to the defect-laden active turbulent state. Despite the distinct symmetry features between these two active turbulence regimes, the flow fluctuations exhibit universal statistical scaling behaviors at large scales, while the spectrum of polarity fluctuations decays exponentially at small length scales compared to the active energy injection length. These findings reveal a dynamical crossover between distinct spatiotemporal organization patterns in polar active matter.","lang":"eng"}],"scopus_import":"1","oa":1,"month":"06","date_created":"2023-09-29T08:46:47Z","publication":"Physical Review Fluids","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","date_published":"2023-06-14T00:00:00Z","article_number":"063101","publication_identifier":{"issn":["2469-990X"]},"arxiv":1,"extern":"1","publication_status":"published","type":"journal_article","date_updated":"2023-10-03T07:25:39Z","issue":"6","article_processing_charge":"No","title":"Symmetry-restoring crossover from defect-free to defect-laden turbulence in polar active matter","author":[{"full_name":"Andersen, Benjamin H.","first_name":"Benjamin H.","last_name":"Andersen"},{"last_name":"Renaud","id":"7af6767d-14eb-11ed-b536-a32449ae867c","first_name":"Julian B","full_name":"Renaud, Julian B"},{"last_name":"Rønning","full_name":"Rønning, Jonas","first_name":"Jonas"},{"first_name":"Luiza","full_name":"Angheluta, Luiza","last_name":"Angheluta"},{"full_name":"Doostmohammadi, Amin","first_name":"Amin","last_name":"Doostmohammadi"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2209.10916"}],"quality_controlled":"1","publisher":"American Physical Society","external_id":{"arxiv":["2209.10916"]},"keyword":["Fluid Flow and Transfer Processes","Modeling and Simulation","Computational Mechanics"],"article_type":"original","day":"14","year":"2023","volume":8},{"type":"journal_article","publication_status":"published","file":[{"relation":"main_file","creator":"dernst","content_type":"application/pdf","file_name":"2023_StochasticProcAppl_Ding.pdf","file_size":1870349,"success":1,"date_created":"2024-01-16T08:47:31Z","file_id":"14806","access_level":"open_access","checksum":"46a708b0cd5569a73d0f3d6c3e0a44dc","date_updated":"2024-01-16T08:47:31Z"}],"department":[{"_id":"LaEr"}],"title":"Spiked multiplicative random matrices and principal components","article_processing_charge":"Yes (in subscription journal)","has_accepted_license":"1","date_updated":"2025-07-16T08:01:03Z","quality_controlled":"1","author":[{"last_name":"Ding","full_name":"Ding, Xiucai","first_name":"Xiucai"},{"last_name":"Ji","id":"dd216c0a-c1f9-11eb-beaf-e9ea9d2de76d","first_name":"Hong Chang","full_name":"Ji, Hong Chang"}],"ddc":["510"],"publisher":"Elsevier","file_date_updated":"2024-01-16T08:47:31Z","article_type":"original","keyword":["Applied Mathematics","Modeling and Simulation","Statistics and Probability"],"project":[{"grant_number":"101020331","call_identifier":"H2020","_id":"62796744-2b32-11ec-9570-940b20777f1d","name":"Random matrices beyond Wigner-Dyson-Mehta"}],"external_id":{"arxiv":["2302.13502"],"isi":["001113615900001"]},"volume":163,"year":"2023","day":"01","isi":1,"acknowledgement":"The authors would like to thank the editor, the associated editor and two anonymous referees for their many critical suggestions which have significantly improved the paper.

Membrane-bound ESCRT-III filaments undergo a series of dramatic composition and geometry changes in the presence of an ATP-consuming Vps4 enzyme, which causes stepwise changes in the membrane morphology. We set out to understand the physical mechanisms involved in translating the changes in ESCRT-III polymer composition into membrane deformation. We have built a coarse-grained model in which ESCRT-III polymers of different geometries and mechanical properties are allowed to copolymerise and bind to a deformable membrane. By modelling ATP-driven stepwise depolymerisation of specific polymers, we identify mechanical regimes in which changes in filament composition trigger the associated membrane transition from a flat to a buckled state, and then to a tubule state that eventually undergoes scission to release a small cargo-loaded vesicle. We then characterise how the location and kinetics of polymer loss affects the extent of membrane deformation and the efficiency of membrane neck scission. Our results identify the near-minimal mechanical conditions for the operation of shape-shifting composite polymers that sever membrane necks."}],"date_created":"2023-01-12T12:08:10Z","publication":"PLOS Computational Biology","month":"10","pmid":1,"oa":1,"intvolume":"        18","_id":"12152","corr_author":"1","citation":{"chicago":"Jiang, Xiuyun, Lena Harker-Kirschneck, Christian Eduardo Vanhille-Campos, Anna-Katharina Pfitzner, Elene Lominadze, Aurélien Roux, Buzz Baum, and Anđela Šarić. “Modelling Membrane Reshaping by Staged Polymerization of ESCRT-III Filaments.” <i>PLOS Computational Biology</i>.

This could be due to the non-equilibrium nature of eukaryotic regulation. Unfortunately, the space of possible non-equilibrium mechanisms is vast and predominantly uninteresting. The key question is therefore how this space can be navigated efficiently, to focus on mechanisms and models that are biologically relevant. In this review, we advocate for the normative role of theory—theory that prescribes rather than just describes—in providing such a focus. Theory should expand its remit beyond inferring mechanistic models from data, towards identifying non-equilibrium gene regulatory schemes that may have been evolutionarily selected, despite their energy consumption, because they are precise, reliable, fast, or otherwise outperform regulation at equilibrium. We illustrate our reasoning by toy examples for which we provide simulation code.","lang":"eng"}],"scopus_import":"1","oa":1,"pmid":1,"date_created":"2023-01-12T12:08:51Z","publication":"Current Opinion in Systems Biology","month":"09","doi":"10.1016/j.coisb.2022.100435","oa_version":"Published Version","citation":{"ista":"Zoller B, Gregor T, Tkačik G. 2022.

Much of the existing literature on direct reciprocity assumes that all competing individuals use the same strategy space. Here, we study both learning and evolutionary dynamics of players that differ in the strategy space they explore. We focus on the infinitely repeated donation game and compare three natural strategy spaces: memory-1 strategies, which consider the last moves of both players, reactive strategies, which respond to the last move of the co-player, and unconditional strategies. These three strategy spaces differ in the memory capacity that is needed. We compute the long term average payoff that is achieved in a pairwise learning process. We find that smaller strategy spaces can dominate larger ones. For weak selection, unconditional players dominate both reactive and memory-1 players. For intermediate selection, reactive players dominate memory-1 players. Only for strong selection and low cost-to-benefit ratio, memory-1 players dominate the others. We observe that the supergame between strategy spaces can be a social dilemma: maximum payoff is achieved if both players explore a larger strategy space, but smaller strategy spaces dominate.","lang":"eng"}],"ec_funded":1,"oa":1,"publication":"PLOS Computational Biology","month":"06","date_created":"2023-01-16T10:02:51Z","pmid":1,"file_date_updated":"2023-01-30T11:28:13Z","project":[{"call_identifier":"H2020","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"keyword":["Computational Theory and Mathematics","Cellular and Molecular Neuroscience","Genetics","Molecular Biology","Ecology","Modeling and Simulation","Ecology","Evolution","Behavior and Systematics"],"external_id":{"isi":["000843626800031"],"pmid":["35700167"]},"article_type":"original","day":"14","volume":18,"year":"2022","acknowledgement":"This work was supported by the European Research Council (https://erc.europa.eu/)\r\nCoG 863818 (ForM-SMArt) (to K.C.), and the European Research Council Starting Grant 850529: E-DIRECT (to C.H.).

In this work, we derive an intuitive but rigorous geometric characterization of the design space of plane elastic rods with variable stiffness. It enables designers to determine which shapes are physically viable with active bending by visual inspection alone. Building on these insights, we propose a method for efficiently designing the geometry of a flat elastic rod that realizes a target equilibrium curve, which only requires solving a linear program. We implement this method in an interactive computational design tool that gives feedback about the feasibility of a design, and computes the geometry of the structural elements necessary to realize it within an instant. The tool also offers an iterative optimization routine that improves the fabricability of a model while modifying it as little as possible. In addition, we use our geometric characterization to derive an algorithm for analyzing and recovering the stability of elastic curves that would otherwise snap out of their unstable equilibrium shapes by buckling. We show the efficacy of our approach by designing and manufacturing several physical models that are assembled from flat elements."}],"scopus_import":"1","ec_funded":1,"publication":"ACM Transactions on Graphics","date_created":"2021-08-08T22:01:26Z","month":"07","oa":1,"related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"12897"}],"link":[{"url":"https://ist.ac.at/en/news/designing-with-elastic-structures/","description":"News on IST Website","relation":"press_release"}]},"date_published":"2021-07-19T00:00:00Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","status":"public","article_number":"126","publication_identifier":{"eissn":["1557-7368"],"issn":["0730-0301"]},"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","image":"/images/cc_by.png","short":"CC BY (4.0)"},"publication_status":"published","type":"journal_article","file":[{"relation":"main_file","file_name":"elastic-curves-paper.pdf","content_type":"application/pdf","creator":"chafner","success":1,"file_size":17064290,"file_id":"10150","date_created":"2021-10-18T10:42:15Z","access_level":"open_access","checksum":"7e5d08ce46b0451b3102eacd3d00f85f","date_updated":"2021-10-18T10:42:15Z"},{"relation":"supplementary_material","file_name":"elastic-curves-supp.pdf","creator":"chafner","content_type":"application/pdf","file_size":547156,"file_id":"10151","date_created":"2021-10-18T10:42:22Z","access_level":"open_access","checksum":"0088643478be7c01a703b5b10767348f","date_updated":"2021-10-18T10:42:22Z"}],"article_processing_charge":"No","title":"The design space of plane elastic curves","department":[{"_id":"BeBi"}],"date_updated":"2026-04-23T22:30:03Z","has_accepted_license":"1","issue":"4","author":[{"first_name":"Christian","full_name":"Hafner, Christian","last_name":"Hafner","id":"400429CC-F248-11E8-B48F-1D18A9856A87"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","last_name":"Bickel","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd","first_name":"Bernd"}],"quality_controlled":"1","publisher":"Association for Computing Machinery","ddc":["516"],"file_date_updated":"2021-10-18T10:42:22Z","article_type":"original","conference":{"location":"Virtual","start_date":"2021-08-09","name":"SIGGRAF: Special Interest Group on Computer Graphics and Interactive Techniques","end_date":"2021-08-13"},"external_id":{"isi":["000674930900091"]},"project":[{"name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","_id":"24F9549A-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"715767"}],"keyword":["Computing methodologies","shape modeling","modeling and simulation","theory of computation","computational geometry","mathematics of computing","mathematical optimization"],"year":"2021","volume":40,"day":"19","isi":1,"acknowledgement":"We thank the anonymous reviewers for their generous feedback, and Michal Piovarči for his help in producing the supplemental video.
