In other words, one could say that a regular function is locally modelled by the set of polynomials. The theory of regularity structures due to Hairer generalizes this observation and provides an abstract setup, which in the application to singular SPDE extends the set of polynomials by functionals constructed from, e.g., white noise. In this context, the notion of Taylor polynomials is lifted to the notion of so-called modelled distributions. The celebrated reconstruction theorem, which in turn was inspired by Gubinelli’s \\textit {sewing lemma}, is of paramount importance for the theory. It enables one to reconstruct a modelled distribution as a true distribution on Rd which is locally approximated by this extended set of models or “monomials”. In the original work of Hairer, the error is measured by means of Hölder norms. This was then generalized to the whole scale of Besov spaces by Hairer and Labbé. It is the aim of this work to adapt the analytic part of the theory of regularity structures to the scale of Triebel–Lizorkin spaces."}]},{"publisher":"Public Library of Science","quality_controlled":"1","oa":1,"date_published":"2020-01-27T00:00:00Z","doi":"10.1371/journal.ppat.1008277","date_created":"2020-02-06T18:47:17Z","day":"27","publication":"PLOS Pathogens","has_accepted_license":"1","isi":1,"year":"2020","project":[{"name":"Structural conservation and diversity in retroviral capsid","grant_number":"P31445","call_identifier":"FWF","_id":"26736D6A-B435-11E9-9278-68D0E5697425"}],"article_number":"e1008277","title":"Structures of immature EIAV Gag lattices reveal a conserved role for IP6 in lentivirus assembly","author":[{"first_name":"Robert A.","full_name":"Dick, Robert A.","last_name":"Dick"},{"first_name":"Chaoyi","last_name":"Xu","full_name":"Xu, Chaoyi"},{"last_name":"Morado","full_name":"Morado, Dustin R.","first_name":"Dustin R."},{"last_name":"Kravchuk","full_name":"Kravchuk, Vladyslav","orcid":"0000-0001-9523-9089","id":"4D62F2A6-F248-11E8-B48F-1D18A9856A87","first_name":"Vladyslav"},{"first_name":"Clifton L.","last_name":"Ricana","full_name":"Ricana, Clifton L."},{"first_name":"Terri D.","last_name":"Lyddon","full_name":"Lyddon, Terri D."},{"full_name":"Broad, Arianna M.","last_name":"Broad","first_name":"Arianna M."},{"full_name":"Feathers, J.

Interactions between the capsid domains (CA) of Gag result in Gag multimerization, leading to an immature virus particle that is formed by a protein lattice based on dimeric, trimeric, and hexameric protein contacts. Among retroviruses the inter- and intra-hexamer contacts differ, especially in the N-terminal sub-domain of CA (CANTD). For HIV-1 the cellular molecule inositol hexakisphosphate (IP6) interacts with and stabilizes the immature hexamer, and is required for production of infectious virus particles. We have used in vitro assembly, cryo-electron tomography and subtomogram averaging, atomistic molecular dynamics simulations and mutational analyses to study the HIV-related lentivirus equine infectious anemia virus (EIAV). In particular, we sought to understand the structural conservation of the immature lentivirus lattice and the role of IP6 in EIAV assembly. Similar to HIV-1, IP6 strongly promoted in vitro assembly of EIAV Gag proteins into virus-like particles (VLPs), which took three morphologically highly distinct forms: narrow tubes, wide tubes, and spheres. Structural characterization of these VLPs to sub-4Å resolution unexpectedly showed that all three morphologies are based on an immature lattice with preserved key structural components, highlighting the structural versatility of CA to form immature assemblies. A direct comparison between EIAV and HIV revealed that both lentiviruses maintain similar immature interfaces, which are established by both conserved and non-conserved residues. In both EIAV and HIV-1, IP6 regulates immature assembly via conserved lysine residues within the CACTD and SP. Lastly, we demonstrate that IP6 stimulates in vitro assembly of immature particles of several other retroviruses in the lentivirus genus, suggesting a conserved role for IP6 in lentiviral assembly."}],"volume":16,"issue":"1","related_material":{"record":[{"relation":"research_data","id":"9723","status":"deleted"}]},"file":[{"checksum":"a297f54d1fef0efe4789ca00f37f241e","file_id":"7484","access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2020-02-11T10:07:28Z","file_name":"2020_PLOSPatho_Dick.pdf","creator":"dernst","date_updated":"2020-07-14T12:47:59Z","file_size":4551246}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["1553-7374"]},"publication_status":"published","status":"public","article_type":"original","type":"journal_article","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":"7464","department":[{"_id":"FlSc"}],"file_date_updated":"2020-07-14T12:47:59Z","ddc":["570"],"date_updated":"2023-10-17T12:29:34Z"},{"title":"Limits on amplifiers of natural selection under death-Birth updating","article_processing_charge":"No","external_id":{"isi":["000510916500025"],"arxiv":["1906.02785"]},"author":[{"orcid":"0000-0002-1097-9684","full_name":"Tkadlec, Josef","last_name":"Tkadlec","first_name":"Josef","id":"3F24CCC8-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Andreas","id":"49704004-F248-11E8-B48F-1D18A9856A87","full_name":"Pavlogiannis, Andreas","orcid":"0000-0002-8943-0722","last_name":"Pavlogiannis"},{"orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Nowak","full_name":"Nowak, Martin A.","first_name":"Martin A."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Tkadlec, J., Pavlogiannis, A., Chatterjee, K., & Nowak, M.

Amplifiers of natural selection are population structures that increase the fixation probability of advantageous mutants, compared to well-mixed populations. Extensive studies have shown that many amplifiers exist for the Birth-death Moran process, some of them substantially increasing the fixation probability or even guaranteeing fixation in the limit of large population size. On the other hand, no amplifiers are known for the death-Birth Moran process, and computer-assisted exhaustive searches have failed to discover amplification. In this work we resolve this disparity, by showing that any amplification under death-Birth updating is necessarily bounded and transient. Our boundedness result states that even if a population structure does amplify selection, the resulting fixation probability is close to that of the well-mixed population. Our transience result states that for any population structure there exists a threshold r⋆ such that the population structure ceases to amplify selection if the mutant fitness advantage r is larger than r⋆. Finally, we also extend the above results to δ-death-Birth updating, which is a combination of Birth-death and death-Birth updating. On the positive side, we identify population structures that maintain amplification for a wide range of values r and δ. These results demonstrate that amplification of natural selection depends on the specific mechanisms of the evolutionary process.","lang":"eng"}]},{"department":[{"_id":"KrCh"},{"_id":"GradSch"}],"file_date_updated":"2020-07-14T12:47:52Z","supervisor":[{"first_name":"Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee"}],"date_updated":"2023-10-17T12:29:46Z","ddc":["519"],"type":"dissertation","status":"public","_id":"7196","related_material":{"record":[{"id":"7210","status":"public","relation":"dissertation_contains"},{"relation":"dissertation_contains","id":"5751","status":"public"},{"status":"public","id":"7212","relation":"dissertation_contains"}]},"publication_identifier":{"eissn":["2663-337X"]},"publication_status":"published","degree_awarded":"PhD","file":[{"date_created":"2020-01-12T11:49:49Z","file_name":"thesis.zip","creator":"jtkadlec","date_updated":"2020-07-14T12:47:52Z","file_size":21100497,"checksum":"451f8e64b0eb26bf297644ac72bfcbe9","file_id":"7255","access_level":"closed","relation":"source_file","content_type":"application/zip"},{"file_name":"2020_Tkadlec_Thesis.pdf","date_created":"2020-01-28T07:32:42Z","file_size":11670983,"date_updated":"2020-07-14T12:47:52Z","creator":"dernst","file_id":"7367","checksum":"d8c44cbc4f939c49a8efc9d4b8bb3985","content_type":"application/pdf","relation":"main_file","access_level":"open_access"}],"language":[{"iso":"eng"}],"alternative_title":["ISTA Thesis"],"month":"01","abstract":[{"text":"In this thesis we study certain mathematical aspects of evolution. The two primary forces that drive an evolutionary process are mutation and selection. Mutation generates new variants in a population. Selection chooses among the variants depending on the reproductive rates of individuals. Evolutionary processes are intrinsically random – a new mutation that is initially present in the population at low frequency can go extinct, even if it confers a reproductive advantage. The overall rate of evolution is largely determined by two quantities: the probability that an invading advantageous mutation spreads through the population (called fixation probability) and the time until it does so (called fixation time). Both those quantities crucially depend not only on the strength of the invading mutation but also on the population structure. In this thesis, we aim to understand how the underlying population structure affects the overall rate of evolution. Specifically, we study population structures that increase the fixation probability of advantageous mutants (called amplifiers of selection). Broadly speaking, our results are of three different types: We present various strong amplifiers, we identify regimes under which only limited amplification is feasible, and we propose population structures that provide different tradeoffs between high fixation probability and short fixation time.","lang":"eng"}],"oa_version":"Published Version","author":[{"id":"3F24CCC8-F248-11E8-B48F-1D18A9856A87","first_name":"Josef","orcid":"0000-0002-1097-9684","full_name":"Tkadlec, Josef","last_name":"Tkadlec"}],"article_processing_charge":"No","title":"A role of graphs in evolutionary processes","citation":{"chicago":"Tkadlec, Josef. “A Role of Graphs in Evolutionary Processes.” Institute of Science and Technology Austria, 2020. https://doi.org/10.15479/AT:ISTA:7196.","ista":"Tkadlec J. 2020.

In this paper, we shed light on this\r\nphenomenon: we show that the combination of stochastic gradient descent (SGD)\r\nand over-parameterization makes the landscape of multilayer neural networks\r\napproximately connected and thus more favorable to optimization. More\r\nspecifically, we prove that SGD solutions are connected via a piecewise linear\r\npath, and the increase in loss along this path vanishes as the number of\r\nneurons grows large. This result is a consequence of the fact that the\r\nparameters found by SGD are increasingly dropout stable as the network becomes\r\nwider. We show that, if we remove part of the neurons (and suitably rescale the\r\nremaining ones), the change in loss is independent of the total number of\r\nneurons, and it depends only on how many neurons are left. Our results exhibit\r\na mild dependence on the input dimension: they are dimension-free for two-layer\r\nnetworks and depend linearly on the dimension for multilayer networks. We\r\nvalidate our theoretical findings with numerical experiments for different\r\narchitectures and classification tasks.","lang":"eng"}],"oa_version":"Published Version","month":"07","intvolume":" 119","publication_status":"published","file":[{"success":1,"file_id":"9217","checksum":"f042c8d4316bd87c6361aa76f1fbdbbe","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_name":"2020_PMLR_Shevchenko.pdf","date_created":"2021-03-02T15:38:14Z","file_size":5336380,"date_updated":"2021-03-02T15:38:14Z","creator":"dernst"}],"language":[{"iso":"eng"}],"volume":119},{"oa":1,"publisher":"De Gruyter","quality_controlled":"1","acknowledgement":"The authors of this paper thank Roland Roth for suggesting the analysis of the weighted\r\ncurvature derivatives for the purpose of improving molecular dynamics simulations and for his continued encouragement.

The main tool is the connection, due to the self-duality of the process, between the invariance principle for single particles starting from all points and the macroscopic behavior of the density field. While the hydrodynamic limit at fixed macroscopic times is obtained via a generalization to the time-inhomogeneous context of the strategy introduced in [41], in order to prove tightness for the sequence of empirical density fields we develop a new criterion based on the notion of uniform conditional stochastic continuity, following [50]. In conclusion, we show that uniform elliptic dynamic conductances provide an example of environments in which the so-called arbitrary starting point invariance principle may be derived from the invariance principle of a single particle starting from the origin. Therefore, our hydrodynamics result applies to the examples of quenched environments considered in, e.g., [1], [3], [6] in combination with the hypothesis of uniform ellipticity."}],"ec_funded":1,"volume":25,"language":[{"iso":"eng"}],"file":[{"creator":"dernst","file_size":696653,"date_updated":"2020-12-28T08:24:08Z","file_name":"2020_ElectronJProbab_Redig.pdf","date_created":"2020-12-28T08:24:08Z","relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"file_id":"8976","checksum":"d75359b9814e78d57c0a481b7cde3751"}],"publication_status":"published","publication_identifier":{"eissn":["1083-6489"]},"status":"public","article_type":"original","type":"journal_article","_id":"8973","file_date_updated":"2020-12-28T08:24:08Z","department":[{"_id":"JaMa"}],"ddc":["510"],"date_updated":"2023-10-17T12:51:56Z","oa":1,"publisher":" Institute of Mathematical Statistics","quality_controlled":"1","acknowledgement":"We warmly thank S.R.S.

They are usually inspired by – and fitted to – experimental data, but they rarely produce neural dynamics that serve complex functions. These failures suggest that current plasticity models are still under-constrained by existing data. Here, we present an alternative approach that uses meta-learning to discover plausible synaptic plasticity rules. Instead of experimental data, the rules are constrained by the functions they implement and the structure they are meant to produce. Briefly, we parameterize synaptic plasticity rules by a Volterra expansion and then use supervised learning methods (gradient descent or evolutionary strategies) to minimize a problem-dependent loss function that quantifies how effectively a candidate plasticity rule transforms an initially random network into one with the desired function. We first validate our approach by re-discovering previously described plasticity rules, starting at the single-neuron level and “Oja’s rule”, a simple Hebbian plasticity rule that captures the direction of most variability of inputs to a neuron (i.e., the first principal component). We expand the problem to the network level and ask the framework to find Oja’s rule together with an anti-Hebbian rule such that an initially random two-layer firing-rate network will recover several principal components of the input space after learning. Next, we move to networks of integrate-and-fire neurons with plastic inhibitory afferents. We train for rules that achieve a target firing rate by countering tuned excitation. Our algorithm discovers a specific subset of the manifold of rules that can solve this task. Our work is a proof of principle of an automated and unbiased approach to unveil synaptic plasticity rules that obey biological constraints and can solve complex functions.","lang":"eng"}],"department":[{"_id":"TiVo"}],"date_updated":"2023-10-18T09:20:55Z","status":"public","conference":{"end_date":"2020-12-12","location":"Vancouver, Canada","start_date":"2020-12-06","name":"NeurIPS: Conference on Neural Information Processing Systems"},"type":"conference","_id":"9633"},{"_id":"8943","status":"public","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)"},"ddc":["580"],"date_updated":"2023-11-16T13:03:31Z","department":[{"_id":"JiFr"}],"file_date_updated":"2020-12-14T07:33:39Z","pmid":1,"oa_version":"Published Version","abstract":[{"lang":"eng","text":"The widely used non-steroidal anti-inflammatory drugs (NSAIDs) are derivatives of the phytohormone salicylic acid (SA). SA is well known to regulate plant immunity and development, whereas there have been few reports focusing on the effects of NSAIDs in plants. Our studies here reveal that NSAIDs exhibit largely overlapping physiological activities to SA in the model plant Arabidopsis. NSAID treatments lead to shorter and agravitropic primary roots and inhibited lateral root organogenesis. Notably, in addition to the SA-like action, which in roots involves binding to the protein phosphatase 2A (PP2A), NSAIDs also exhibit PP2A-independent effects. Cell biological and biochemical analyses reveal that many NSAIDs bind directly to and inhibit the chaperone activity of TWISTED DWARF1, thereby regulating actin cytoskeleton dynamics and subsequent endosomal trafficking. Our findings uncover an unexpected bioactivity of human pharmaceuticals in plants and provide insights into the molecular mechanism underlying the cellular action of this class of anti-inflammatory compounds."}],"acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"}],"month":"12","intvolume":" 33","scopus_import":"1","file":[{"date_created":"2020-12-14T07:33:39Z","file_name":"2020_CellReports_Tan.pdf","date_updated":"2020-12-14T07:33:39Z","file_size":8056434,"creator":"dernst","checksum":"ed18cba0fb48ed2e789381a54cc21904","file_id":"8948","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["22111247"]},"publication_status":"published","related_material":{"link":[{"relation":"press_release","url":"https://ist.ac.at/en/news/plants-on-aspirin/","description":"News on IST Homepage"}]},"issue":"9","volume":33,"ec_funded":1,"article_number":"108463","project":[{"name":"Tracing Evolution of Auxin Transport and Polarity in Plants","grant_number":"742985","call_identifier":"H2020","_id":"261099A6-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FP7","_id":"25681D80-B435-11E9-9278-68D0E5697425","grant_number":"291734","name":"International IST Postdoc Fellowship Programme"},{"grant_number":"723-2015","name":"Long Term Fellowship","_id":"256FEF10-B435-11E9-9278-68D0E5697425"}],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","citation":{"chicago":"Tan, Shutang, Martin Di Donato, Matous Glanc, Xixi Zhang, Petr Klíma, Jie Liu, Aurélien Bailly, et al. “Non-Steroidal Anti-Inflammatory Drugs Target TWISTED DWARF1-Regulated Actin Dynamics and Auxin Transport-Mediated Plant Development.” Cell Reports.

This in particular is also believed to apply to cardiovascular flows where inertial forces are typically too low to sustain turbulence. On the other hand, flow instabilities and fluctuating shear stresses are held responsible for a variety of cardiovascular diseases. Here we report a nonlinear instability mechanism for pulsating pipe flow that gives rise to bursts of turbulence at low flow rates. Geometrical distortions of small, yet finite, amplitude are found to excite a state consisting of helical vortices during flow deceleration. The resulting flow pattern grows rapidly in magnitude, breaks down into turbulence, and eventually returns to laminar when the flow accelerates. This scenario causes shear stress fluctuations and flow reversal during each pulsation cycle. Such unsteady conditions can adversely affect blood vessels and have been shown to promote inflammation and dysfunction of the shear stress-sensitive endothelial cell layer.","lang":"eng"}],"ec_funded":1,"related_material":{"record":[{"status":"public","id":"12726","relation":"dissertation_contains"},{"relation":"dissertation_contains","id":"14530","status":"public"}],"link":[{"description":"News on IST Homepage","url":"https://ist.ac.at/en/news/blood-flows-more-turbulent-than-previously-expected/","relation":"press_release"}]},"issue":"21","volume":117,"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["00278424"],"eissn":["10916490"]},"project":[{"call_identifier":"FWF","_id":"238B8092-32DE-11EA-91FC-C7463DDC885E","grant_number":"I04188","name":"Instabilities in pulsating pipe flow of Newtonian and complex fluids"},{"_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411"}],"title":"Nonlinear hydrodynamic instability and turbulence in pulsatile flow","external_id":{"isi":["000536797100014"],"arxiv":["2005.11190"]},"article_processing_charge":"No","author":[{"first_name":"Duo","id":"3454D55E-F248-11E8-B48F-1D18A9856A87","last_name":"Xu","full_name":"Xu, Duo"},{"id":"2A2006B2-F248-11E8-B48F-1D18A9856A87","first_name":"Atul","full_name":"Varshney, Atul","orcid":"0000-0002-3072-5999","last_name":"Varshney"},{"id":"34BADBA6-F248-11E8-B48F-1D18A9856A87","first_name":"Xingyu","last_name":"Ma","full_name":"Ma, Xingyu","orcid":"0000-0002-0179-9737"},{"first_name":"Baofang","last_name":"Song","full_name":"Song, Baofang"},{"orcid":"0000-0003-4844-6311","full_name":"Riedl, Michael","last_name":"Riedl","first_name":"Michael","id":"3BE60946-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Marc","last_name":"Avila","full_name":"Avila, Marc"},{"id":"3A374330-F248-11E8-B48F-1D18A9856A87","first_name":"Björn","last_name":"Hof","orcid":"0000-0003-2057-2754","full_name":"Hof, Björn"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ista":"Xu D, Varshney A, Ma X, Song B, Riedl M, Avila M, Hof B. 2020.

Here, z lies in the complex upper half-plane, a is a self-adjoint element of A and S is a positivity-preserving linear operator on A. We show that m is the Stieltjes transform of a compactly supported A-valued measure on R. Under suitable assumptions, we establish that this measure has a uniformly 1/3-Hölder continuous density with respect to the Lebesgue measure, which is supported on finitely many intervals, called bands. In fact, the density is analytic inside the bands with a square-root growth at the edges and internal cubic root cusps whenever the gap between two bands vanishes. The shape of these singularities is universal and no other singularity may occur. We give a precise asymptotic description of m near the singular points. These asymptotics generalize the analysis at the regular edges given in the companion paper on the Tracy-Widom universality for the edge eigenvalue statistics for correlated random matrices [the first author et al., Ann. Probab. 48, No. 2, 963--1001 (2020; Zbl 1434.60017)] and they play a key role in the proof of the Pearcey universality at the cusp for Wigner-type matrices [G. Cipolloni et al., Pure Appl.

Emerging evidence suggests that interneurons may also be affected, but a detailed characterization of interneuron loss and its potential impacts on motor neuron loss and disease progression is lacking. To examine this issue, the fate of V1 inhibitory neurons during ALS was assessed in the ventral spinal cord using the SODG93A mouse model. The V1 population makes up ∼30% of all ventral inhibitory neurons, ∼50% of direct inhibitory synaptic contacts onto motor neuron cell bodies, and is thought to play a key role in modulating motor output, in part through recurrent and reciprocal inhibitory circuits. We find that approximately half of V1 inhibitory neurons are lost in SODG93A mice at late disease stages, but that this loss is delayed relative to the loss of motor neurons and V2a excitatory neurons. We further identify V1 subpopulations based on transcription factor expression that are differentially susceptible to degeneration in SODG93A mice. At an early disease stage, we show that V1 synaptic contacts with motor neuron cell bodies increase, suggesting an upregulation of inhibition before V1 neurons are lost in substantial numbers. These data support a model in which progressive changes in V1 synaptic contacts early in disease, and in select V1 subpopulations at later stages, represent a compensatory upregulation and then deleterious breakdown of specific interneuron circuits within the spinal cord."}],"month":"12","intvolume":" 450","scopus_import":"1"},{"oa_version":"Published Version","abstract":[{"text":"Semiconductor nanowires have been playing a crucial role in the development of nanoscale devices for the realization of spin qubits, Majorana fermions, single photon emitters, nanoprocessors, etc. The monolithic growth of site‐controlled nanowires is a prerequisite toward the next generation of devices that will require addressability and scalability. Here, combining top‐down nanofabrication and bottom‐up self‐assembly, the growth of Ge wires on prepatterned Si (001) substrates with controllable position, distance, length, and structure is reported. This is achieved by a novel growth process that uses a SiGe strain‐relaxation template and can be potentially generalized to other material combinations. Transport measurements show an electrically tunable spin–orbit coupling, with a spin–orbit length similar to that of III–V materials. Also, charge sensing between quantum dots in closely spaced wires is observed, which underlines their potential for the realization of advanced quantum devices. The reported results open a path toward scalable qubit devices using nanowires on silicon.","lang":"eng"}],"acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"intvolume":" 32","month":"04","scopus_import":"1","language":[{"iso":"eng"}],"file":[{"file_id":"8782","checksum":"c622737dc295972065782558337124a2","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_created":"2020-11-20T10:11:35Z","file_name":"2020_AdvancedMaterials_Gao.pdf","date_updated":"2020-11-20T10:11:35Z","file_size":5242880,"creator":"dernst"}],"publication_status":"published","publication_identifier":{"issn":["0935-9648"]},"ec_funded":1,"issue":"16","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"7996"},{"status":"public","id":"9222","relation":"research_data"}]},"volume":32,"_id":"7541","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)"},"type":"journal_article","article_type":"original","ddc":["530"],"date_updated":"2024-02-21T12:42:12Z","department":[{"_id":"GeKa"}],"file_date_updated":"2020-11-20T10:11:35Z","acknowledgement":"This work was supported by the National Key R&D Program of China (Grant Nos. 2016YFA0301701 and 2016YFA0300600), the NSFC (Grant Nos. 11574356, 11434010, and 11404252), the Strategic Priority Research Program of CAS (Grant No. XDB30000000), the ERC Starting Grant No. 335497, the FWF P32235 project, and the European Union's Horizon 2020 research and innovation program under Grant Agreement #862046.

Among their remarkable properties are, for example, aesthetics of organic shapes, ability to evenly distribute loads, or efficient flow separation. They find applications across vast length scales ranging from sky-scraper architecture to microscopic devices. But, at\r\nthe same time, the design of curved shells and their manufacturing process pose a variety of challenges. In this thesis, they are addressed from several perspectives. In particular, this thesis presents approaches based on the transformation of initially flat sheets into the target curved surfaces. This involves problems of interactive design of shells with nontrivial mechanical constraints, inverse design of complex structural materials, and data-driven modeling of delicate and time-dependent physical properties. At the same time, two newly-developed self-morphing mechanisms targeting flat-to-curved transformation are presented.\r\nIn architecture, doubly curved surfaces can be realized as cold bent glass panelizations. Originally flat glass panels are bent into frames and remain stressed. This is a cost-efficient fabrication approach compared to hot bending, when glass panels are shaped plastically. However such constructions are prone to breaking during bending, and it is highly\r\nnontrivial to navigate the design space, keeping the panels fabricable and aesthetically pleasing at the same time. We introduce an interactive design system for cold bent glass façades, while previously even offline optimization for such scenarios has not been sufficiently developed. Our method is based on a deep learning approach providing quick\r\nand high precision estimation of glass panel shape and stress while handling the shape\r\nmultimodality.\r\nFabrication of smaller objects of scales below 1 m, can also greatly benefit from shaping originally flat sheets. In this respect, we designed new self-morphing shell mechanisms transforming from an initial flat state to a doubly curved state with high precision and detail. Our so-called CurveUps demonstrate the encodement of the geometric information\r\ninto the shell. Furthermore, we explored the frontiers of programmable materials and showed how temporal information can additionally be encoded into a flat shell. This allows prescribing deformation sequences for doubly curved surfaces and, thus, facilitates self-collision avoidance enabling complex shapes and functionalities otherwise impossible.\r\nBoth of these methods include inverse design tools keeping the user in the design loop.","lang":"eng"}],"month":"09","alternative_title":["ISTA Thesis"],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"chicago":"Guseinov, Ruslan. “Computational Design of Curved Thin Shells: From Glass Façades to Programmable Matter.” Institute of Science and Technology Austria, 2020. https://doi.org/10.15479/AT:ISTA:8366.","ista":"Guseinov R. 2020.

They are produced by attaching planar glass sheets to curved frames and require keeping the occurring stress within safe limits.\r\nHowever, it is very challenging to navigate the design space of cold bent glass panels due to the fragility of the material, which impedes the form-finding for practically feasible and aesthetically pleasing cold bent glass facades. We propose an interactive, data-driven approach for designing cold bent glass facades that can be seamlessly integrated into a typical architectural design pipeline. Our method allows non-expert users to interactively edit a parametric surface while providing real-time feedback on the deformed shape and maximum stress of cold bent glass panels. Designs are automatically refined to minimize several fairness criteria while maximal stresses are kept within glass limits. We achieve interactive frame rates by using a differentiable Mixture Density Network trained from more than a million simulations. Given a curved boundary, our regression model is capable of handling multistable\r\nconfigurations and accurately predicting the equilibrium shape of the panel and its corresponding maximal stress. We show predictions are highly accurate and validate our results with a physical realization of a cold bent glass surface.","lang":"eng"}],"intvolume":" 39","month":"11","scopus_import":"1","ddc":["000"],"date_updated":"2024-02-21T12:43:21Z","file_date_updated":"2023-05-23T20:54:43Z","department":[{"_id":"BeBi"}],"_id":"8562","status":"public","type":"journal_article","article_type":"original","publication":"ACM Transactions on Graphics","day":"26","year":"2020","isi":1,"has_accepted_license":"1","date_created":"2020-09-23T11:30:02Z","doi":"10.1145/3414685.3417843","date_published":"2020-11-26T00:00:00Z","acknowledgement":"We thank IST Austria’s Scientific Computing team for their support, Corinna Datsiou and Sophie Pennetier for their expert input on the practical applications of cold bent glass, and Zaha Hadid Architects and Waagner Biro for providing the architectural datasets.

Here we investigated the activity-dependent modification of these connections during exploratory behavior in rats by optogenetically inhibiting pyramidal cell and interneuron subpopulations. Light application and associated firing alteration of pyramidal and interneuron populations led to lasting changes in pyramidal-interneuron connection weights as indicated by spike transmission changes. Spike transmission alterations were predicted by the light-mediated changes in the number of pre- and postsynaptic spike pairing events and by firing rate changes of interneurons but not pyramidal cells. This work demonstrates the presence of activity-dependent associative and non-associative reorganization of pyramidal-interneuron connections triggered by the optogenetic modification of the firing rate and spike synchrony of cells."}],"month":"10","intvolume":" 9","scopus_import":"1","file":[{"content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"6a7b0543c440f4c000a1864e69377d95","file_id":"8749","success":1,"date_updated":"2020-11-09T09:17:40Z","file_size":447669,"creator":"dernst","date_created":"2020-11-09T09:17:40Z","file_name":"2020_eLife_Gridchyn.pdf"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2050084X"]},"publication_status":"published","related_material":{"record":[{"relation":"research_data","id":"8563","status":"public"}]},"volume":9,"_id":"8740","status":"public","article_type":"original","type":"journal_article","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)"},"ddc":["570"],"date_updated":"2024-02-21T12:43:40Z","file_date_updated":"2020-11-09T09:17:40Z","department":[{"_id":"JoCs"}]},{"keyword":["Design","Synthesis and processing","Mechanical engineering","Polymers"],"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":"7262","file_date_updated":"2020-07-14T12:47:55Z","department":[{"_id":"BeBi"}],"ddc":["000"],"date_updated":"2024-02-21T12:45:02Z","intvolume":" 11","month":"01","scopus_import":"1","oa_version":"Published Version","abstract":[{"text":"Advances in shape-morphing materials, such as hydrogels, shape-memory polymers and light-responsive polymers have enabled prescribing self-directed deformations of initially flat geometries. However, most proposed solutions evolve towards a target geometry without considering time-dependent actuation paths. To achieve more complex geometries and avoid self-collisions, it is critical to encode a spatial and temporal shape evolution within the initially flat shell. Recent realizations of time-dependent morphing are limited to the actuation of few, discrete hinges and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding temporal shape evolution in architected shells that assume complex shapes and doubly curved geometries. The shells are non-periodic tessellations of pre-stressed contractile unit cells that soften in water at rates prescribed locally by mesostructure geometry. The ensuing midplane contraction is coupled to the formation of encoded curvatures. We propose an inverse design tool based on a data-driven model for unit cells’ temporal responses.","lang":"eng"}],"ec_funded":1,"related_material":{"link":[{"relation":"press_release","url":"https://ist.ac.at/en/news/geometry-meets-time/","description":"News on IST Homepage"}],"record":[{"status":"public","id":"8366","relation":"dissertation_contains"},{"id":"7154","status":"public","relation":"research_data"}]},"volume":11,"language":[{"iso":"eng"}],"file":[{"date_created":"2020-01-15T14:35:34Z","file_name":"2020_NatureComm_Guseinov.pdf","date_updated":"2020-07-14T12:47:55Z","file_size":1315270,"creator":"rguseino","checksum":"7db23fef2f4cda712f17f1004116ddff","file_id":"7336","content_type":"application/pdf","access_level":"open_access","relation":"main_file"}],"publication_status":"published","publication_identifier":{"issn":["2041-1723"]},"project":[{"_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships"},{"grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425"}],"article_number":"237","title":"Programming temporal morphing of self-actuated shells","article_processing_charge":"No","external_id":{"isi":["000511916800015"]},"author":[{"last_name":"Guseinov","full_name":"Guseinov, Ruslan","orcid":"0000-0001-9819-5077","first_name":"Ruslan","id":"3AB45EE2-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Connor","last_name":"McMahan","full_name":"McMahan, Connor"},{"full_name":"Perez Rodriguez, Jesus","last_name":"Perez Rodriguez","id":"2DC83906-F248-11E8-B48F-1D18A9856A87","first_name":"Jesus"},{"first_name":"Chiara","full_name":"Daraio, Chiara","last_name":"Daraio"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","first_name":"Bernd","last_name":"Bickel","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"chicago":"Guseinov, Ruslan, Connor McMahan, Jesus Perez Rodriguez, Chiara Daraio, and Bernd Bickel. “Programming Temporal Morphing of Self-Actuated Shells.” Nature Communications.

We observe that existing hybridization techniques for safety analysis that over-approximate nonlinear dynamical systems by switched affine inclusion dynamics and provide fixed approximation error, do not suffice for stability analysis. Hence, we propose a hybridization method that provides a state-dependent error which converges to zero as the state tends to the equilibrium point. The crux of our hybridization computation is an elegant recursive algorithm that uses partial derivatives of a given function to obtain upper and lower bound matrices for the over-approximating linear inclusion. We illustrate our method on some examples to demonstrate the application of the theory for stability analysis. In particular, our method is able to establish stability of a nonlinear system which does not admit a polynomial Lyapunov function."}],"file_date_updated":"2021-02-26T16:38:14Z","department":[{"_id":"ToHe"}],"ddc":["000"],"date_updated":"2024-02-22T13:25:19Z","status":"public","conference":{"end_date":"2020-12-04","location":"Houston, TX, USA ","start_date":"2020-12-01","name":"RTTS: Real-Time Systems Symposium"},"type":"conference","_id":"9202"},{"oa":1,"publisher":"Springer","quality_controlled":"1","acknowledgement":"We would like to thank P.

The zebrafish embryo has emerged as a vital model system to address the cellular and molecular mechanisms that drive epiboly. In the zebrafish embryo, the blastoderm, consisting of a simple squamous epithelium (the enveloping layer) and an underlying mass of deep cells, as well as a yolk nuclear syncytium (the yolk syncytial layer) undergo epiboly to internalize the yolk cell during gastrulation. The major events during zebrafish epiboly are: expansion of the enveloping layer and the internal yolk syncytial layer, reduction and removal of the yolk membrane ahead of the advancing blastoderm margin and deep cell rearrangements between the enveloping layer and yolk syncytial layer to thin the blastoderm. Here, work addressing the cellular and molecular mechanisms as well as the sources of the mechanical forces that underlie these events is reviewed. The contribution of recent findings to the current model of epiboly as well as open questions and future prospects are also discussed."}],"month":"01","intvolume":" 136","scopus_import":"1","language":[{"iso":"eng"}],"publication_identifier":{"isbn":["9780128127988"],"issn":["0070-2153"]},"publication_status":"published","volume":136,"series_title":"Current Topics in Developmental Biology","_id":"7410","status":"public","type":"book_chapter","date_updated":"2024-02-22T13:23:09Z","department":[{"_id":"CaHe"}]},{"date_updated":"2024-02-22T14:57:30Z","ddc":["004"],"file_date_updated":"2020-07-14T12:47:45Z","department":[{"_id":"ChLa"}],"_id":"6944","article_type":"original","type":"journal_article","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","publication_identifier":{"issn":["0920-5691"],"eissn":["1573-1405"]},"publication_status":"published","file":[{"date_updated":"2020-07-14T12:47:45Z","file_size":1715072,"creator":"dernst","date_created":"2019-11-26T10:30:02Z","file_name":"2019_IJCV_Sun.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"155e63edf664dcacb3bdc1c2223e606f","file_id":"7110"}],"language":[{"iso":"eng"}],"related_material":{"record":[{"status":"public","id":"6482","relation":"earlier_version"}],"link":[{"url":"https://doi.org/10.1007/s11263-019-01262-5","relation":"erratum"}]},"issue":"4","volume":128,"ec_funded":1,"abstract":[{"text":"We study the problem of automatically detecting if a given multi-class classifier operates outside of its specifications (out-of-specs), i.e. on input data from a different distribution than what it was trained for. This is an important problem to solve on the road towards creating reliable computer vision systems for real-world applications, because the quality of a classifier’s predictions cannot be guaranteed if it operates out-of-specs. Previously proposed methods for out-of-specs detection make decisions on the level of single inputs. This, however, is insufficient to achieve low false positive rate and high false negative rates at the same time. In this work, we describe a new procedure named KS(conf), based on statistical reasoning. Its main component is a classical Kolmogorov–Smirnov test that is applied to the set of predicted confidence values for batches of samples. Working with batches instead of single samples allows increasing the true positive rate without negatively affecting the false positive rate, thereby overcoming a crucial limitation of single sample tests. We show by extensive experiments using a variety of convolutional network architectures and datasets that KS(conf) reliably detects out-of-specs situations even under conditions where other tests fail. It furthermore has a number of properties that make it an excellent candidate for practical deployment: it is easy to implement, adds almost no overhead to the system, works with any classifier that outputs confidence scores, and requires no a priori knowledge about how the data distribution could change.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","month":"04","intvolume":" 128","citation":{"ieee":"R.

For probabilistic programs the notion is naturally extended to expected sensitivity. A previous approach develops a relational program logic framework for proving expected sensitivity of probabilistic while loops, where the number of iterations is fixed and bounded. In this work, we consider probabilistic while loops where the number of iterations is not fixed, but randomized and depends on the initial input values. We present a sound approach for proving expected sensitivity of such programs. Our sound approach is martingale-based and can be automated through existing martingale-synthesis algorithms. Furthermore, our approach is compositional for sequential composition of while loops under a mild side condition. We demonstrate the effectiveness of our approach on several classical examples from Gambler's Ruin, stochastic hybrid systems and stochastic gradient descent. We also present experimental results showing that our automated approach can handle various probabilistic programs in the literature.","lang":"eng"}],"month":"01","intvolume":" 4","scopus_import":"1","ddc":["004"],"date_updated":"2024-02-22T15:16:45Z","file_date_updated":"2020-09-01T11:12:58Z","department":[{"_id":"KrCh"}],"_id":"8324","status":"public","type":"conference","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)"}},{"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Salazar, Juan Esteban, et al. “Anatomical Specializations Related to Foraging in the Visual System of a Nocturnal Insectivorous Bird, the Band-Winged Nightjar (Aves: Caprimulgiformes).” Brain, Behavior and Evolution, vol. 94, no. 1–4, Karger Publishers, 2020, pp. 27–36, doi:10.1159/000504162.","apa":"Salazar, J.

Most nocturnal birds have several visual specializations, such as enlarged eyes and an increased orbital convergence. However, the actual role of binocular vision in nocturnal foraging is still debated. Nightjars (Aves: Caprimulgidae) are predators that actively pursue and capture flying insects in crepuscular and nocturnal environments, mainly using a conspicuous “sit-and-wait” tactic on which pursuit begins with an insect flying over the bird that sits on the ground. In this study, we describe the visual system of the band-winged nightjar (Systellura longirostris), with emphasis on anatomical features previously described as relevant for nocturnal birds. Orbit convergence, determined by 3D scanning of the skull, was 73.28°. The visual field, determined by ophthalmoscopic reflex, exhibits an area of maximum binocular overlap of 42°, and it is dorsally oriented. The eyes showed a nocturnal-like normalized corneal aperture/axial length index. Retinal ganglion cells (RGCs) were relatively scant, and distributed in an unusual oblique-band pattern, with higher concentrations in the ventrotemporal quadrant. Together, these results indicate that the band-winged nightjar exhibits a retinal specialization associated with the binocular area of their dorsal visual field, a relevant area for pursuit triggering and prey attacks. The RGC distribution observed is unusual among birds, but similar to that of some visually dependent insectivorous bats, suggesting that those features might be convergent in relation to feeding strategies.","lang":"eng"}],"intvolume":" 94","month":"01","scopus_import":"1"},{"publication_status":"published","publication_identifier":{"issn":["0091-1798"]},"language":[{"iso":"eng"}],"ec_funded":1,"related_material":{"record":[{"relation":"dissertation_contains","id":"149","status":"public"},{"relation":"dissertation_contains","id":"6179","status":"public"}]},"volume":48,"issue":"2","abstract":[{"lang":"eng","text":"We prove edge universality for a general class of correlated real symmetric or complex Hermitian Wigner matrices with arbitrary expectation.

It is regulated by ubiquitination, a post-translational modification crucial for the proper sorting of endocytosed PM proteins to the vacuole for subsequent degradation. To understand the significance and the variety of roles played by this reversible modification, the function of ubiquitin receptors, which translate the ubiquitin signature into a cellular response, needs to be elucidated. In this study, we show that TOL (TOM1-like) proteins function in plants as multivalent ubiquitin receptors, governing ubiquitinated cargo delivery to the vacuole via the conserved Endosomal Sorting Complex Required for Transport (ESCRT) pathway. TOL2 and TOL6 interact with components of the ESCRT machinery and bind to K63-linked ubiquitin via two tandemly arranged conserved ubiquitin-binding domains. Mutation of these domains results not only in a loss of ubiquitin binding but also altered localization, abolishing TOL6 ubiquitin receptor activity. Function and localization of TOL6 is itself regulated by ubiquitination, whereby TOL6 ubiquitination potentially modulates degradation of PM-localized cargoes, assisting in the fine-tuning of the delicate interplay between protein recycling and downregulation. Taken together, our findings demonstrate the function and regulation of a ubiquitin receptor that mediates vacuolar degradation of PM proteins in higher plants."}],"pmid":1,"oa_version":"Published Version","issue":"5","volume":13,"publication_status":"published","publication_identifier":{"issn":["1674-2052"]},"language":[{"iso":"eng"}],"file":[{"checksum":"c538a5008f7827f62d17d40a3bfabe65","file_id":"15038","success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2024-02-28T12:39:56Z","file_name":"2020_MolecularPlant_MoulinierAnzola.pdf","creator":"dernst","date_updated":"2024-02-28T12:39:56Z","file_size":3089212}],"external_id":{"pmid":["32087370"]},"article_processing_charge":"No","author":[{"first_name":"Jeanette","last_name":"Moulinier-Anzola","full_name":"Moulinier-Anzola, Jeanette"},{"first_name":"Maximilian","last_name":"Schwihla","full_name":"Schwihla, Maximilian"},{"full_name":"De-Araújo, Lucinda","last_name":"De-Araújo","first_name":"Lucinda"},{"last_name":"Artner","full_name":"Artner, Christina","id":"45DF286A-F248-11E8-B48F-1D18A9856A87","first_name":"Christina"},{"first_name":"Lisa","full_name":"Jörg, Lisa","last_name":"Jörg"},{"last_name":"Konstantinova","full_name":"Konstantinova, Nataliia","first_name":"Nataliia"},{"last_name":"Luschnig","full_name":"Luschnig, Christian","first_name":"Christian"},{"last_name":"Korbei","full_name":"Korbei, Barbara","first_name":"Barbara"}],"title":"TOLs function as ubiquitin receptors in the early steps of the ESCRT pathway in higher plants","citation":{"mla":"Moulinier-Anzola, Jeanette, et al. “TOLs Function as Ubiquitin Receptors in the Early Steps of the ESCRT Pathway in Higher Plants.” Molecular Plant, vol. 13, no. 5, Elsevier, 2020, pp. 717–31, doi:10.1016/j.molp.2020.02.012.","ieee":"J.

These are formed between SEPT2 and SEPT6 and between SEPT7 and SEPT3, and their description permits an understanding of the structural basis for the selectivity necessary for correct filament assembly. By replacing SEPT6 by SEPT8 or SEPT11, it is possible to rationalize Kinoshita's postulate, which predicts the exchangeability of septins from within a subgroup. Switches I and II, which in classical small GTPases provide a mechanism for nucleotide-dependent conformational change, have been repurposed in septins to play a fundamental role in molecular recognition. Specifically, it is switch I which holds the key to discriminating between the two different G-interfaces. Moreover, residues which are characteristic for a given subgroup play subtle, but pivotal, roles in guaranteeing that the correct interfaces are formed."}],"department":[{"_id":"MaLo"}],"date_updated":"2024-02-28T12:37:54Z","status":"public","keyword":["Molecular Biology","Structural Biology"],"article_type":"original","type":"journal_article","_id":"15036"},{"status":"public","article_type":"original","type":"journal_article","_id":"8384","file_date_updated":"2020-11-23T09:03:19Z","department":[{"_id":"ChWo"}],"ddc":["000"],"date_updated":"2024-02-28T12:57:31Z","month":"07","intvolume":" 39","scopus_import":"1","main_file_link":[{"url":"https://doi.org/10.1145/3386569.3392405","open_access":"1"}],"oa_version":"Submitted Version","abstract":[{"text":"Previous research on animations of soap bubbles, films, and foams largely focuses on the motion and geometric shape of the bubble surface.

In this paper, we model these natural phenomena by introducing the film thickness as a reduced degree of freedom in the Navier-Stokes equations and deriving their equations of motion. We discretize the equations on a nonmanifold triangle mesh surface and couple it to an existing bubble solver. In doing so, we also introduce an incompressible fluid solver for 2.5D films and a novel advection algorithm for convecting fields across non-manifold surface junctions. Our simulations enhance state-of-the-art bubble solvers with additional effects caused by convection, rippling, draining, and evaporation of the thin film.","lang":"eng"}],"acknowledged_ssus":[{"_id":"ScienComp"}],"volume":39,"issue":"4","ec_funded":1,"file":[{"date_updated":"2020-11-23T09:03:19Z","file_size":14935529,"creator":"dernst","date_created":"2020-11-23T09:03:19Z","file_name":"2020_soapfilm_submitted.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"813831ca91319d794d9748c276b24578","file_id":"8795","success":1}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["15577368"],"issn":["07300301"]},"publication_status":"published","project":[{"_id":"2533E772-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"638176","name":"Efficient Simulation of Natural Phenomena at Extremely Large Scales"}],"article_number":"31","title":"A model for soap film dynamics with evolving thickness","author":[{"full_name":"Ishida, Sadashige","last_name":"Ishida","first_name":"Sadashige","id":"6F7C4B96-A8E9-11E9-A7CA-09ECE5697425"},{"full_name":"Synak, Peter","last_name":"Synak","id":"331776E2-F248-11E8-B48F-1D18A9856A87","first_name":"Peter"},{"full_name":"Narita, Fumiya","last_name":"Narita","first_name":"Fumiya"},{"full_name":"Hachisuka, Toshiya","last_name":"Hachisuka","first_name":"Toshiya"},{"id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87","first_name":"Christopher J","last_name":"Wojtan","orcid":"0000-0001-6646-5546","full_name":"Wojtan, Christopher J"}],"external_id":{"isi":["000583700300004"]},"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Ishida, Sadashige, et al. “A Model for Soap Film Dynamics with Evolving Thickness.” ACM Transactions on Graphics, vol. 39, no. 4, 31, Association for Computing Machinery, 2020, doi:10.1145/3386569.3392405.","short":"S.

It has been developed as a tool to solve (typically graph) problems in systems where the input is distributed over many machines with limited space.\r\n\t\r\nRecent work has focused on the regime in which machines have sublinear (in $n$, the number of nodes in the input graph) space, with randomized algorithms presented for fundamental graph problems of Maximal Matching and Maximal Independent Set. However, there have been no prior corresponding deterministic algorithms.\r\n\t\r\n\tA major challenge underlying the sublinear space setting is that the local space of each machine might be too small to store all the edges incident to a single node. This poses a considerable obstacle compared to the classical models in which each node is assumed to know and have easy access to its incident edges. To overcome this barrier we introduce a new graph sparsification technique that deterministically computes a low-degree subgraph with additional desired properties. The degree of the nodes in this subgraph is small in the sense that the edges of each node can be now stored on a single machine. This low-degree subgraph also has the property that solving the problem on this subgraph provides \\emph{significant} global progress, i.e., progress towards solving the problem for the original input graph.\r\n\t\r\nUsing this framework to derandomize the well-known randomized algorithm of Luby [SICOMP'86], we obtain $O(\\log \\Delta+\\log\\log n)$-round deterministic MPC algorithms for solving the fundamental problems of Maximal Matching and Maximal Independent Set with $O(n^{\\epsilon})$ space on each machine for any constant $\\epsilon > 0$. Based on the recent work of Ghaffari et al. [FOCS'18], this additive $O(\\log\\log n)$ factor is conditionally essential. These algorithms can also be shown to run in $O(\\log \\Delta)$ rounds in the closely related model of CONGESTED CLIQUE, improving upon the state-of-the-art bound of $O(\\log^2 \\Delta)$ rounds by Censor-Hillel et al.

By relying on numerical properties of the keys, interpolation search achieves lower search complexity and better performance. Although interpolation-based data structures were investigated in the past, their non-blocking concurrent variants have received very little attention so far.\r\nIn this paper, we propose the first non-blocking implementation of the classic interpolation search tree (IST) data structure. For arbitrary key distributions, the data structure ensures worst-case O(log n + p) amortized time for search, insertion and deletion traversals. When the input key distributions are smooth, lookups run in expected O(log log n + p) time, and insertion and deletion run in expected amortized O(log log n + p) time, where p is a bound on the number of threads. To improve the scalability of concurrent insertion and deletion, we propose a novel parallel rebuilding technique, which should be of independent interest.\r\nWe evaluate whether the theoretical improvements translate to practice by implementing the concurrent interpolation search tree, and benchmarking it on uniform and nonuniform key distributions, for dataset sizes in the millions to billions of keys. Relative to the state-of-the-art concurrent data structures, the concurrent interpolation search tree achieves performance improvements of up to 15% under high update rates, and of up to 50% under moderate update rates. Further, ISTs exhibit up to 2X less cache-misses, and consume 1.2 -- 2.6X less memory compared to the next best alternative on typical dataset sizes. We find that the results are surprisingly robust to distributional skew, which suggests that our data structure can be a promising alternative to classic concurrent search structures."}],"month":"02","main_file_link":[{"url":"https://doi.org/10.1145/3332466.3374542","open_access":"1"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"isbn":["9781450368186"]},"ec_funded":1},{"abstract":[{"lang":"eng","text":"There has been a significant amount of research on hardware and software support for efficient concurrent data structures; yet, the question of how to build correct, simple, and scalable data structures has not yet been definitively settled.

We provide several examples showing that this mechanism can enable fast and arguably simple concurrent data structure designs, such as lists, binary search trees, balanced search trees, range queries, and Software Transactional Memory (STM) implementations. We provide an implementation of memory tags in the Graphite multi-core simulator, showing that the mechanism can be implemented entirely at the level of L1 cache, and that it can enable non-trivial speedups versus existing implementations of the above data structures."}],"oa_version":"None","publisher":"Association for Computing Machinery","quality_controlled":"1","scopus_import":"1","month":"07","isi":1,"publication_identifier":{"isbn":["9781450369350"]},"publication_status":"published","year":"2020","day":"06","publication":"Annual ACM Symposium on Parallelism in Algorithms and Architectures","language":[{"iso":"eng"}],"page":"37-49","doi":"10.1145/3350755.3400213","issue":"7","date_published":"2020-07-06T00:00:00Z","date_created":"2020-08-02T22:00:58Z","_id":"8191","type":"conference","conference":{"name":"SPAA: Symposium on Parallelism in Algorithms and Architectures","start_date":"2020-07-15","end_date":"2020-07-17","location":"Virtual Event, United States"},"status":"public","citation":{"chicago":"Alistarh, Dan-Adrian, Trevor A Brown, and Nandini Singhal. “Memory Tagging: Minimalist Synchronization for Scalable Concurrent Data Structures.” In Annual ACM Symposium on Parallelism in Algorithms and Architectures, 37–49.

We accomplish this through numerical homogenization: we first use a large number of yarn-level simulations to build a model of the potential energy density of the cloth, and then use this energy density function to compute forces in a thin shell simulator. We model several yarn-based materials, including both woven and knitted fabrics. Our model faithfully reproduces expected effects like the stiffness of woven fabrics, and the highly deformable nature and anisotropy of knitted fabrics. Our approach does not require any real-world experiments nor measurements; because the method is based entirely on simulations, it can generate entirely new material models quickly, without the need for testing apparatuses or human intervention. We provide data-driven models of several woven and knitted fabrics, which can be used for efficient simulation with an off-the-shelf cloth solver.","lang":"eng"}],"oa_version":"Submitted Version","external_id":{"isi":["000583700300021"]},"article_processing_charge":"No","author":[{"last_name":"Sperl","full_name":"Sperl, Georg","id":"4DD40360-F248-11E8-B48F-1D18A9856A87","first_name":"Georg"},{"full_name":"Narain, Rahul","last_name":"Narain","first_name":"Rahul"},{"last_name":"Wojtan","orcid":"0000-0001-6646-5546","full_name":"Wojtan, Christopher J","first_name":"Christopher J","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87"}],"title":"Homogenized yarn-level cloth","citation":{"ista":"Sperl G, Narain R, Wojtan C. 2020.

The shear-induced ordering is analyzed by means of principal component analysis and artificial neural networks, which are applied to data of reduced dimensionality.

To understand their origin, we examine the interplay of Zeeman coupling and superconducting pairings in three-dimensional metals with band inversion. Weak Zeeman fields are found to suppress intraorbital spin-singlet pairing, known to localize the states at the ends of the vortices on the surface. On the other hand, an orbital-triplet pairing is shown to be stable against Zeeman interactions, but leads to delocalized zero-energy Majorana modes which extend through the vortex. In contrast, the finite-energy vortex modes remain localized at the vortex ends even when the pairing is of orbital-triplet form. Phenomenologically, this manifests as an observed disappearance of zero-bias peaks within the cores of topological vortices upon an increase of the applied magnetic field. The presence of magnetic impurities in FeTe(1−x)Sex, which are attracted to the vortices, would lead to such Zeeman-induced delocalization of Majorana modes in a fraction of vortices that capture a large enough number of magnetic impurities. Our results provide an explanation for the dichotomy between topological and nontopological vortices recently observed in FeTe(1−x)Sex.","lang":"eng"}],"intvolume":" 101","month":"01","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1907.02077"}],"scopus_import":"1","date_updated":"2024-02-28T13:11:13Z","department":[{"_id":"MiLe"}],"_id":"7428","status":"public","article_type":"original","type":"journal_article"},{"issue":"1","volume":102,"publication_status":"published","publication_identifier":{"issn":["24699926"],"eissn":["24699934"]},"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://arxiv.org/abs/1912.08334","open_access":"1"}],"scopus_import":"1","intvolume":" 102","month":"07","abstract":[{"text":"We demonstrate that releasing atoms into free space from an optical lattice does not deteriorate cavity-generated spin squeezing for metrological purposes.

A classical optimization criterion for MDPs is to maximize the expected discounted-sum payoff, which ignores low probability catastrophic events with highly negative impact on the system. On the other hand, risk-averse policies require the probability of undesirable events to be below a given threshold, but they do not account for optimization of the expected payoff. We consider MDPs with discounted-sum payoff with failure states which represent catastrophic outcomes. The objective of risk-constrained planning is to maximize the expected discounted-sum payoff among risk-averse policies that ensure the probability to encounter a failure state is below a desired threshold. Our main contribution is an efficient risk-constrained planning algorithm that combines UCT-like search with a predictor learned through interaction with the MDP (in the style of AlphaZero) and with a risk-constrained action selection via linear programming.

VRK-1, the single Caenorhabditis elegans VRK ortholog, functions in cell division and germline proliferation. However, the role of VRK-1 in postmitotic cells and adult life span remains unknown. Here, we show that VRK-1 increases organismal longevity by activating the cellular energy sensor, AMP-activated protein kinase (AMPK), via direct phosphorylation. We found that overexpression of vrk-1 in the soma of adult C. elegans increased life span and, conversely, inhibition of vrk-1 decreased life span. In addition, vrk-1 was required for longevity conferred by mutations that inhibit C. elegans mitochondrial respiration, which requires AMPK. VRK-1 directly phosphorylated and up-regulated AMPK in both C. elegans and cultured human cells. Thus, our data show that the somatic nuclear kinase, VRK-1, promotes longevity through AMPK activation, and this function appears to be conserved between C. elegans and humans."}],"oa_version":"Published Version","month":"07","intvolume":" 6","publication_identifier":{"eissn":["2375-2548"]},"publication_status":"published","file":[{"creator":"dernst","date_updated":"2024-03-04T09:46:41Z","file_size":1864415,"date_created":"2024-03-04T09:46:41Z","file_name":"2020_ScienceAdvances_Park.pdf","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"15058","checksum":"a37157cd0de709dce5fe03f4a31cd0b6","success":1}],"language":[{"iso":"eng"}],"volume":6,"issue":"27","_id":"15057","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","short":"CC BY-NC (4.0)"},"status":"public","date_updated":"2024-03-04T09:52:09Z","ddc":["570"],"file_date_updated":"2024-03-04T09:46:41Z","department":[{"_id":"MaDe"}]},{"article_type":"original","type":"journal_article","status":"public","_id":"15061","department":[{"_id":"CaBe"}],"date_updated":"2024-03-04T10:14:44Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1073/pnas.191726911"}],"month":"09","intvolume":" 117","abstract":[{"text":"The actin cytoskeleton, a dynamic network of actin filaments and associated F-actin–binding proteins, is fundamentally important in eukaryotes. α-Actinins are major F-actin bundlers that are inhibited by Ca2+ in nonmuscle cells. Here we report the mechanism of Ca2+-mediated regulation of Entamoeba histolytica α-actinin-2 (EhActn2) with features expected for the common ancestor of Entamoeba and higher eukaryotic α-actinins. Crystal structures of Ca2+-free and Ca2+-bound EhActn2 reveal a calmodulin-like domain (CaMD) uniquely inserted within the rod domain. Integrative studies reveal an exceptionally high affinity of the EhActn2 CaMD for Ca2+, binding of which can only be regulated in the presence of physiological concentrations of Mg2+. Ca2+ binding triggers an increase in protein multidomain rigidity, reducing conformational flexibility of F-actin–binding domains via interdomain cross-talk and consequently inhibiting F-actin bundling. In vivo studies uncover that EhActn2 plays an important role in phagocytic cup formation and might constitute a new drug target for amoebic dysentery.","lang":"eng"}],"acknowledged_ssus":[{"_id":"LifeSc"}],"oa_version":"Published Version","pmid":1,"issue":"36","volume":117,"publication_identifier":{"issn":["0027-8424"],"eissn":["1091-6490"]},"publication_status":"published","language":[{"iso":"eng"}],"author":[{"first_name":"Nikos","full_name":"Pinotsis, Nikos","last_name":"Pinotsis"},{"last_name":"Zielinska","full_name":"Zielinska, Karolina","first_name":"Karolina"},{"first_name":"Mrigya","last_name":"Babuta","full_name":"Babuta, Mrigya"},{"full_name":"Arolas, Joan L.","last_name":"Arolas","first_name":"Joan L."},{"first_name":"Julius","full_name":"Kostan, Julius","last_name":"Kostan"},{"first_name":"Muhammad Bashir","last_name":"Khan","full_name":"Khan, Muhammad Bashir"},{"full_name":"Schreiner, Claudia","last_name":"Schreiner","first_name":"Claudia"},{"last_name":"Testa Salmazo","full_name":"Testa Salmazo, Anita P","first_name":"Anita P","id":"41F1F098-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Ciccarelli, Luciano","last_name":"Ciccarelli","first_name":"Luciano"},{"last_name":"Puchinger","full_name":"Puchinger, Martin","first_name":"Martin"},{"first_name":"Eirini A.","last_name":"Gkougkoulia","full_name":"Gkougkoulia, Eirini A."},{"first_name":"Euripedes de Almeida","full_name":"Ribeiro, Euripedes de Almeida","last_name":"Ribeiro"},{"first_name":"Thomas C.","last_name":"Marlovits","full_name":"Marlovits, Thomas C."},{"first_name":"Alok","last_name":"Bhattacharya","full_name":"Bhattacharya, Alok"},{"first_name":"Kristina","last_name":"Djinovic-Carugo","full_name":"Djinovic-Carugo, Kristina"}],"external_id":{"pmid":["32848067"]},"article_processing_charge":"No","title":"Calcium modulates the domain flexibility and function of an α-actinin similar to the ancestral α-actinin","citation":{"mla":"Pinotsis, Nikos, et al. “Calcium Modulates the Domain Flexibility and Function of an α-Actinin Similar to the Ancestral α-Actinin.” Proceedings of the National Academy of Sciences, vol. 117, no. 36, Proceedings of the National Academy of Sciences, 2020, pp. 22101–12, doi:10.1073/pnas.1917269117.","ieee":"N.
