Here, we propose several types of contextual modulation for associative memory networks that greatly increase their performance. In these networks, context inactivates specific neurons and connections, which modulates the effective connectivity of the network. Memories are stored only by the active components, thereby reducing interference from memories acquired in other contexts. Such networks exhibit several beneficial characteristics, including enhanced memory capacity, high robustness to noise, increased robustness to memory overloading, and better memory retention during continual learning. Furthermore, memories can be biased to have different relative strengths, or even gated on or off, according to contextual cues, providing a candidate model for cognitive control of memory and efficient memory search. An external context-encoding network can dynamically switch the memory network to a desired state, which we liken to experimentally observed contextual signals in prefrontal cortex and hippocampus. Overall, our work illustrates the benefits of organizing memory around context, and provides an important link between behavioral studies of memory and mechanistic details of neural circuits.SIGNIFICANCEMemory is context dependent — both encoding and recall vary in effectiveness and speed depending on factors like location and brain state during a task. We apply this idea to a simple computational model of associative memory through contextual gating of neurons and synaptic connections. Intriguingly, this results in several advantages, including vastly enhanced memory capacity, better robustness, and flexible memory gating. Our model helps to explain (i) how gating and inhibition contribute to memory processes, (ii) how memory access dynamically changes over time, and (iii) how context representations, such as those observed in hippocampus and prefrontal cortex, may interact with and control memory processes."}],"publisher":"Cold Spring Harbor Laboratory","publication_status":"published","department":[{"_id":"TiVo"}],"month":"12","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication":"bioRxiv","oa":1,"day":"21","citation":{"short":"W.F.

A natural (and efficient) way to approximate an isomanifold is to consider its Piecewise-Linear (PL) approximation based on a triangulation T of the ambient space Rd. In this paper, we give conditions under which the PL-approximation of an isomanifold is topologically equivalent to the isomanifold. The conditions are easy to satisfy in the sense that they can always be met by taking a sufficiently\r\nfine triangulation T . This contrasts with previous results on the triangulation of manifolds where, in arbitrary dimensions, delicate perturbations are needed to guarantee topological correctness, which leads to strong limitations in practice. We further give a bound on the Fréchet distance between the original isomanifold and its PL-approximation. Finally we show analogous results for the PL-approximation of an isomanifold with boundary.","lang":"eng"}],"file":[{"date_created":"2021-07-14T06:44:36Z","relation":"main_file","file_id":"9650","file_name":"Boissonnat-Wintraecken2021_Article_TheTopologicalCorrectnessOfPLA.pdf","date_updated":"2021-07-14T06:44:36Z","file_size":1455699,"content_type":"application/pdf","checksum":"f1d372ec3c08ec22e84f8e93e1126b8c","creator":"mwintrae","access_level":"open_access"}],"quality_controlled":"1","article_processing_charge":"Yes (via OA deal)","oa_version":"Published Version","date_created":"2021-07-14T06:44:53Z","ec_funded":1,"_id":"9649","year":"2022"},{"external_id":{"isi":["000822975900002"]},"title":"Multitier mechanics control stromal adaptations in swelling lymph nodes","project":[{"_id":"25FE9508-B435-11E9-9278-68D0E5697425","grant_number":"724373","call_identifier":"H2020","name":"Cellular navigation along spatial gradients"}],"has_accepted_license":"1","date_updated":"2023-08-02T06:53:07Z","citation":{"mla":"Assen, Frank P., et al. “Multitier Mechanics Control Stromal Adaptations in Swelling Lymph Nodes.” Nature Immunology, vol. 23, Springer Nature, 2022, pp. 1246–55, doi:10.1038/s41590-022-01257-4.","ieee":"F.

We identified lymphocyte trapping by influx and proliferation as drivers of an outward pressure force, causing fibroblastic reticular cells of the T-zone (TRCs) and their associated conduits to stretch. After an initial phase of relaxation, TRCs sensed the resulting strain through cell matrix adhesions, which coordinated local growth and remodeling of the stromal network. While the expanded TRC network readopted its typical configuration, a massive fibrotic reaction of the organ capsule set in and countered further organ expansion. Thus, different fibroblast populations mechanically control LN swelling in a multitier fashion.","lang":"eng"}],"file":[{"checksum":"628e7b49809f22c75b428842efe70c68","content_type":"application/pdf","file_size":11475325,"access_level":"open_access","creator":"dernst","file_name":"2022_NatureImmunology_Assen.pdf","file_id":"11642","success":1,"date_created":"2022-07-25T07:11:32Z","relation":"main_file","date_updated":"2022-07-25T07:11:32Z"}],"quality_controlled":"1","article_processing_charge":"No","oa_version":"Published Version","acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"PreCl"},{"_id":"LifeSc"}],"date_created":"2021-08-06T09:09:11Z","ec_funded":1,"_id":"9794","year":"2022","date_published":"2022-07-11T00:00:00Z","doi":"10.1038/s41590-022-01257-4","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"status":"public","language":[{"iso":"eng"}],"intvolume":" 23","ddc":["570"],"type":"journal_article","volume":23,"file_date_updated":"2022-07-25T07:11:32Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","month":"07","publisher":"Springer Nature","department":[{"_id":"SiHi"},{"_id":"CaHe"},{"_id":"EdHa"},{"_id":"EM-Fac"},{"_id":"Bio"},{"_id":"MiSi"}],"isi":1,"page":"1246-1255","acknowledgement":"This research was supported by the Scientific Service Units of IST Austria through resources provided by the Imaging and Optics, Electron Microscopy, Preclinical and Life Science Facilities.

Here, we explored the development of the neurotransmitter identity of neurons of the avian nucleus isthmi parvocellularis (Ipc), whose axon terminals are retinotopically arranged in the optic tectum (TeO) and exert a focal gating effect upon the ascending transmission of retinal inputs. Although cholinergic and glutamatergic markers are both found in Ipc neurons and terminals of adult pigeons and chicks, the mRNA expression of the vesicular acetylcholine transporter, VAChT, is weak or absent. To explore how the Ipc neurotransmitter identity is established during ontogeny, we analyzed the expression of mRNAs coding for cholinergic (ChAT, VAChT, and CHT) and glutamatergic (VGluT2 and VGluT3) markers in chick embryos at different developmental stages. We found that between E12 and E18, Ipc neurons expressed all cholinergic mRNAs and also VGluT2 mRNA; however, from E16 through posthatch stages, VAChT mRNA expression was specifically diminished. Our ex vivo deposits of tracer crystals and intracellular filling experiments revealed that Ipc axons exhibit a mature paintbrush morphology late in development, experiencing marked morphological transformations during the period of presumptive dual vesicular transmitter release. Additionally, although ChAT protein immunoassays increasingly label the growing Ipc axon, this labeling was consistently restricted to sparse portions of the terminal branches. Combined, these results suggest that the synthesis of glutamate and acetylcholine, and their vesicular release, is complexly linked to the developmental processes of branching, growing and remodeling of these unique axons.","lang":"eng"}],"publication_status":"published","article_type":"original","publication":"Journal of Comparative Neurology","publication_identifier":{"issn":["0021-9967"],"eissn":["1096-9861"]},"day":"01","citation":{"short":"R.

This problem generalizes the SCC decomposition problem of graphs and closed recurrent sets of Markov chains. The model of symbolic algorithms is widely used in formal verification and model-checking, where access to the input model is restricted to only symbolic operations (e.g., basic set operations and computation of one-step neighborhood). For an input MDP with n vertices and m edges, the classical symbolic algorithm from the 1990s for the MEC decomposition requires O(n2) symbolic operations and O(1) symbolic space. The only other symbolic algorithm for the MEC decomposition requires O(nm−−√) symbolic operations and O(m−−√) symbolic space. A main open question is whether the worst-case O(n2) bound for symbolic operations can be beaten. We present a symbolic algorithm that requires O˜(n1.5) symbolic operations and O˜(n−−√) symbolic space. Moreover, the parametrization of our algorithm provides a trade-off between symbolic operations and symbolic space: for all 0<ϵ≤1/2 the symbolic algorithm requires O˜(n2−ϵ) symbolic operations and O˜(nϵ) symbolic space ( O˜ hides poly-logarithmic factors). Using our techniques we present faster algorithms for computing the almost-sure winning regions of ω -regular objectives for MDPs. We consider the canonical parity objectives for ω -regular objectives, and for parity objectives with d -priorities we present an algorithm that computes the almost-sure winning region with O˜(n2−ϵ) symbolic operations and O˜(nϵ) symbolic space, for all 0<ϵ≤1/2 .","lang":"eng"}],"publication_status":"published","oa_version":"Preprint","article_processing_charge":"No","keyword":["Computer science","Computational modeling","Markov processes","Probabilistic logic","Formal verification","Game Theory"],"quality_controlled":"1","year":"2021","_id":"10002","ec_funded":1,"date_created":"2021-09-12T22:01:24Z"},{"keyword":["Computer science","Heuristic algorithms","Memory management","Automata","Markov processes","Probability distribution","Complexity theory"],"article_processing_charge":"No","oa_version":"Preprint","quality_controlled":"1","abstract":[{"lang":"eng","text":"Markov chains are the de facto finite-state model for stochastic dynamical systems, and Markov decision processes (MDPs) extend Markov chains by incorporating non-deterministic behaviors. Given an MDP and rewards on states, a classical optimization criterion is the maximal expected total reward where the MDP stops after T steps, which can be computed by a simple dynamic programming algorithm. We consider a natural generalization of the problem where the stopping times can be chosen according to a probability distribution, such that the expected stopping time is T, to optimize the expected total reward. Quite surprisingly we establish inter-reducibility of the expected stopping-time problem for Markov chains with the Positivity problem (which is related to the well-known Skolem problem), for which establishing either decidability or undecidability would be a major breakthrough. Given the hardness of the exact problem, we consider the approximate version of the problem: we show that it can be solved in exponential time for Markov chains and in exponential space for MDPs."}],"publication_status":"published","_id":"10004","year":"2021","ec_funded":1,"date_created":"2021-09-12T22:01:25Z","title":"Stochastic processes with expected stopping time","external_id":{"isi":["000947350400036"],"arxiv":["2104.07278"]},"project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818","call_identifier":"H2020"}],"oa":1,"publication_identifier":{"issn":["1043-6871"],"isbn":["978-1-6654-4896-3"],"eisbn":["978-1-6654-4895-6"]},"publication":"Proceedings of the 36th Annual ACM/IEEE Symposium on Logic in Computer Science","day":"07","date_updated":"2025-07-14T09:10:08Z","author":[{"first_name":"Krishnendu","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X"},{"first_name":"Laurent","last_name":"Doyen","full_name":"Doyen, Laurent"}],"citation":{"ama":"Chatterjee K, Doyen L.

This setting, broad enough in terms of applications, significantly expands the paradigm of nonlinear parabolic problems. Formulating four conditions concerning the form of the implicit equation, we first show that these conditions describe a maximal monotone p-coercive graph. We then establish the global-in-time and large-data existence of a (weak) solution and its uniqueness. To this end, we adopt and significantly generalize Minty’s method of monotone mappings. A unified theory, containing several novel tools, is developed in a way to be tractable from the point of view of numerical approximations."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","volume":31,"intvolume":" 31","doi":"10.1142/S0218202521500457","date_published":"2021-08-25T00:00:00Z","language":[{"iso":"eng"}],"status":"public","acknowledgement":"M.

The specific examples being treated are two-phase Navier-Stokes flow with surface tension, modeling the evolution of two incompressible, viscous and immiscible fluids separated by a sharp interface, and multiphase mean curvature flow, which serves as an idealized model for the motion of grain boundaries in an annealing polycrystalline material. Our main results - obtained in joint works with Julian Fischer, Tim Laux and Theresa M. Simon - state that prior to the formation of geometric singularities due to topology changes, the weak solution concept of Abels (Interfaces Free Bound. 9, 2007) to two-phase Navier-Stokes flow with surface tension and the weak solution concept of Laux and Otto (Calc. Var. Partial Differential Equations 55, 2016) to multiphase mean curvature flow (for networks in R^2 or double bubbles in R^3) represents the unique solution to these interface evolution problems within the class of classical solutions, respectively. To the best of the author's knowledge, for interface evolution problems not admitting a geometric comparison principle the derivation of a weak-strong uniqueness principle represented an open problem, so that the works contained in the present thesis constitute the first positive results in this direction. The key ingredient of our approach consists of the introduction of a novel concept of relative entropies for a class of curvature driven interface evolution problems, for which the associated energy contains an interfacial contribution being proportional to the surface area of the evolving (network of) interface(s). The interfacial part of the relative entropy gives sufficient control on the interface error between a weak and a classical solution, and its time evolution can be computed, at least in principle, for any energy dissipating weak solution concept. A resulting stability estimate for the relative entropy essentially entails the above mentioned weak-strong uniqueness principles. The present thesis contains a detailed introduction to our relative entropy approach, which in particular highlights potential applications to other problems in curvature driven interface evolution not treated in this thesis.","lang":"eng"}],"file":[{"date_created":"2021-09-13T11:03:24Z","relation":"source_file","file_id":"10008","file_name":"thesis_final_Hensel.zip","date_updated":"2021-09-15T14:37:30Z","file_size":15022154,"content_type":"application/x-zip-compressed","checksum":"c8475faaf0b680b4971f638f1db16347","creator":"shensel","access_level":"closed"},{"checksum":"1a609937aa5275452822f45f2da17f07","file_size":6583638,"content_type":"application/pdf","access_level":"open_access","creator":"shensel","file_name":"thesis_final_Hensel.pdf","file_id":"10014","date_created":"2021-09-13T14:18:56Z","relation":"main_file","date_updated":"2021-09-14T09:52:47Z"}],"related_material":{"record":[{"status":"public","id":"10012","relation":"part_of_dissertation"},{"id":"10013","status":"public","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","status":"public","id":"7489"}]},"publication_status":"published","article_processing_charge":"No","oa_version":"Published Version","_id":"10007","year":"2021","date_created":"2021-09-13T11:12:34Z","ec_funded":1,"title":"Curvature driven interface evolution: Uniqueness properties of weak solution concepts","project":[{"name":"International IST Doctoral Program","call_identifier":"H2020","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"},{"name":"Bridging Scales in Random Materials","call_identifier":"H2020","_id":"0aa76401-070f-11eb-9043-b5bb049fa26d","grant_number":"948819"}],"has_accepted_license":"1","supervisor":[{"last_name":"Fischer","first_name":"Julian L","orcid":"0000-0002-0479-558X","full_name":"Fischer, Julian L","id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87"}],"citation":{"short":"S.

These solutions are evolving varifolds, just as in Brakke's formulation, but are coupled to the phase volumes by a simple transport equation. First, we show that, in the exact same setup as in Ilmanen's proof [J. Differential Geom. 38, 417-461, (1993)], any limit point of solutions to the Allen-Cahn equation is a varifold solution in our sense. Second, we prove that any calibrated flow in the sense of Fischer et al. [arXiv:2003.05478] - and hence any classical solution to mean curvature flow - is unique in the class of our new varifold solutions. This is in sharp contrast to the case of Brakke flows, which a priori may disappear at any given time and are therefore fatally non-unique. Finally, we propose an extension of the solution concept to the multi-phase case which is at least guaranteed to satisfy a weak-strong uniqueness principle.","lang":"eng"}],"month":"09","publication_status":"submitted","department":[{"_id":"JuFi"}],"keyword":["Mean curvature flow","gradient flows","varifolds","weak solutions","weak-strong uniqueness","calibrated geometry","gradient-flow calibrations"],"article_processing_charge":"No","oa_version":"Preprint","main_file_link":[{"url":"https://arxiv.org/abs/2109.04233","open_access":"1"}],"arxiv":1,"_id":"10011","year":"2021","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 948819), and from the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany’s Excellence Strategy – EXC-2047/1 – 390685813.

Here, we explored the impact of different concentrations of the synthetic auxin NAA that establish growth-promoting and -repressing conditions on the root tip proteome and phosphoproteome, generating a unique resource. From the phosphoproteome data, we pinpointed (novel) growth regulators, such as the RALF34-THE1 module. Our results, together with previously published studies, suggest that auxin, H+-ATPases, cell wall modifications and cell wall sensing receptor-like kinases are tightly embedded in a pathway regulating cell elongation. Furthermore, our study assigned a novel role to MKK2 as a regulator of primary root growth and a (potential) regulator of auxin biosynthesis and signalling, and suggests the importance of the MKK2\r\nThr31 phosphorylation site for growth regulation in the Arabidopsis root tip.","lang":"eng"}],"file":[{"access_level":"open_access","creator":"cchlebak","checksum":"2a9f534b9c2200e72e2cde95afaf4eed","file_size":2667848,"content_type":"application/pdf","date_updated":"2021-09-16T09:07:06Z","file_name":"2021_Cells_Nikonorova.pdf","file_id":"10021","success":1,"relation":"main_file","date_created":"2021-09-16T09:07:06Z"}],"quality_controlled":"1","keyword":["primary root","(phospho)proteomics","auxin","(receptor) kinase"],"article_processing_charge":"Yes","oa_version":"Published Version","pmid":1,"date_created":"2021-09-14T11:36:20Z","ec_funded":1,"_id":"10015","year":"2021","date_published":"2021-07-02T00:00:00Z","doi":"10.3390/cells10071665","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"status":"public","language":[{"iso":"eng"}],"alternative_title":["Protein Phosphorylation and Cell Signaling in Plants"],"ddc":["575"],"intvolume":" 10","type":"journal_article","volume":10,"file_date_updated":"2021-09-16T09:07:06Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"07","publisher":"MDPI","department":[{"_id":"JiFr"}],"isi":1,"acknowledgement":"We thank the Nottingham Stock Centre for seeds, Frank Van Breusegem for the phb3 mutant, and Herman Höfte for the the1 mutant.

These are identified, as is well known, in the case of the variance in terms of an appropriate Hilbertian norm; and in the case of the relative entropy, in terms of a Dirichlet form which morphs into a version of the familiar Fisher information under conditions of detailed balance. Here we obtain trajectorial versions of these results, valid along almost every path of the random motion and most transparent in the backwards direction of time. Martingale arguments and time reversal play crucial roles, as in the recent work of Karatzas, Schachermayer and Tschiderer for conservative diffusions. Extensions are developed to general “convex divergences” and to countable state-spaces. The steepest descent and gradient flow properties for the variance, the relative entropy, and appropriate generalizations, are studied along with their respective geometries under conditions of detailed balance, leading to a very direct proof for the HWI inequality of Otto and Villani in the present context."}],"date_created":"2021-09-19T08:53:19Z","ec_funded":1,"year":"2021","_id":"10023","intvolume":" 21","doi":"10.4310/CIS.2021.v21.n4.a1","date_published":"2021-06-04T00:00:00Z","language":[{"iso":"eng"}],"status":"public","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","type":"journal_article","volume":21,"main_file_link":[{"url":"https://arxiv.org/abs/2005.14177","open_access":"1"}],"department":[{"_id":"JaMa"}],"publisher":"International Press","month":"06","acknowledgement":"I.K. acknowledges support from the U.S. National Science Foundation under Grant NSF-DMS-20-04997.
