The rise of Deep Learning has enabled end-to-end solutions to be learned entirely from data, requiring minimal knowledge about the application area. We design a learning scheme to train end-to-end linear dynamical systems (LDS)s by gradient descent in imitation learning robotic domains. We introduce a new regularization loss component together with a learning algorithm that improves the stability of the learned autonomous system, by forcing the eigenvalues of the internal state updates of an LDS to be negative reals. We evaluate our approach on a series of real-life and simulated robotic experiments, in comparison to linear and nonlinear Recurrent Neural Network (RNN) architectures. Our results show that our stabilizing method significantly improves test performance of LDS, enabling such linear models to match the performance of contemporary nonlinear RNN architectures. A video of the obstacle avoidance performance of our method on a mobile robot, in unseen environments, compared to other methods can be viewed at https://youtu.be/mhEsCoNao5E.","lang":"eng"}],"day":"01","publication_identifier":{"isbn":["9781728173955"],"issn":["1050-4729"]},"publisher":"IEEE","doi":"10.1109/ICRA40945.2020.9196608","file_date_updated":"2020-11-06T10:58:49Z","fulldoi":"https://doi.org/10.1109/ICRA40945.2020.9196608","ddc":["000"],"title":"Gershgorin loss stabilizes the recurrent neural network compartment of an end-to-end robot learning scheme","scopus_import":"1","oa":1,"article_processing_charge":"No","year":"2020","status":"public","_id":"8704","month":"05","conference":{"start_date":"2020-05-31","location":"Paris, France","name":"ICRA: International Conference on Robotics and Automation","end_date":"2020-08-31"},"publication":"Proceedings - IEEE International Conference on Robotics and Automation","alternative_title":["ICRA"],"external_id":{"isi":["000712319503110"]},"page":"5446-5452","citation":{"chicago":"Lechner, Mathias, Ramin Hasani, Daniela Rus, and Radu Grosu. “Gershgorin Loss Stabilizes the Recurrent Neural Network Compartment of an End-to-End Robot Learning Scheme.” In Proceedings - IEEE International Conference on Robotics and Automation, 5446–52.

Traditional synchronous Stochastic Gradient Descent (SGD)\r\nachieves good accuracy for a wide variety of tasks, but relies on global synchronization to accumulate the gradients at every training step. In this paper, we propose eager-SGD, which relaxes the global synchronization for\r\ndecentralized accumulation. To implement eager-SGD, we propose to use two partial collectives: solo and majority. With solo allreduce, the faster processes contribute their gradients eagerly without waiting for the slower processes, whereas with majority allreduce, at least half of the participants must contribute gradients before continuing, all without using a central parameter server.

Specifically, we analyze the situation in which a learning system obtains datasets from multiple sources, some of which might be biased or even adversarially perturbed. It is\r\nknown that in the single-source case, an adversary with the power to corrupt a fixed fraction of the training data can prevent PAC-learnability, that is, even in the limit of infinitely much training data, no learning system can approach the optimal test error. In this work we show that, surprisingly, the same is not true in the multi-source setting, where the adversary can arbitrarily\r\ncorrupt a fixed fraction of the data sources. Our main results are a generalization bound that provides finite-sample guarantees for this learning setting, as well as corresponding lower bounds. Besides establishing PAC-learnability our results also show that in a cooperative learning setting sharing data with other parties has provable benefits, even if some\r\nparticipants are malicious.

Building on the results obtained for full and effective models in the regime of strong spin-orbit coupling, we address the question whether the entanglement found on superexchange bonds always increases when the Ising spin-orbit coupling is added. We show that (i) quantum entanglement is amplified by strong spin-orbit coupling and, surprisingly, (ii) almost classical disentangled states are possible.

Here, we present cryo-electron microscopy structures of ovine complex I in five different conditions, including turnover, at resolutions up to 2.3 to 2.5 angstroms. Resolved water molecules allowed us to experimentally define the proton translocation pathways. Quinone binds at three positions along the quinone cavity, as does the inhibitor rotenone that also binds within subunit ND4. Dramatic conformational changes around the quinone cavity couple the redox reaction to proton translocation during open-to-closed state transitions of the enzyme. In the induced deactive state, the open conformation is arrested by the ND6 subunit. We propose a detailed molecular coupling mechanism of complex I, which is an unexpected combination of conformational changes and electrostatic interactions.","lang":"eng"}],"author":[{"id":"37233050-F248-11E8-B48F-1D18A9856A87","full_name":"Kampjut, Domen","orcid":"0000-0002-6018-3422","first_name":"Domen","last_name":"Kampjut"},{"id":"338D39FE-F248-11E8-B48F-1D18A9856A87","full_name":"Sazanov, Leonid A","orcid":"0000-0002-0977-7989","first_name":"Leonid A","last_name":"Sazanov"}],"pmid":1,"isi":1,"article_number":"eabc4209","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"EM-Fac"}],"date_published":"2020-10-30T00:00:00Z","type":"journal_article","has_accepted_license":"1","intvolume":" 370","quality_controlled":"1","language":[{"iso":"eng"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_created":"2020-11-08T23:01:23Z","oa_version":"Submitted Version","article_type":"original","file":[{"success":1,"content_type":"application/pdf","file_name":"Full_manuscript_with_SI_opt_red.pdf","file_id":"8820","checksum":"658ba90979ca9528a2efdfac8547047a","relation":"main_file","date_updated":"2020-11-26T18:47:58Z","access_level":"open_access","file_size":7618987,"creator":"lsazanov","date_created":"2020-11-26T18:47:58Z"}],"department":[{"_id":"LeSa"}],"publication_status":"published","date_updated":"2026-04-02T14:32:34Z","project":[{"call_identifier":"H2020","name":"International IST Doctoral Program","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425"}],"acknowledgement":"We thank J.

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."}],"related_material":{"record":[{"relation":"research_data","id":"8563","status":"public"}]},"pmid":1,"author":[{"last_name":"Gridchyn","full_name":"Gridchyn, Igor","id":"4B60654C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1807-1929","first_name":"Igor"},{"id":"3B9D816C-F248-11E8-B48F-1D18A9856A87","full_name":"Schönenberger, Philipp","first_name":"Philipp","last_name":"Schönenberger"},{"first_name":"Joseph","id":"426376DC-F248-11E8-B48F-1D18A9856A87","full_name":"O'Neill, Joseph","last_name":"O'Neill"},{"last_name":"Csicsvari","full_name":"Csicsvari, Jozsef L","id":"3FA14672-F248-11E8-B48F-1D18A9856A87","first_name":"Jozsef L","orcid":"0000-0002-5193-4036"}],"article_number":"61106","isi":1,"corr_author":"1"},{"citation":{"short":"A.K.

An understanding of those tipping elements is of great interest given the increasing influence of humans on the biophysical Earth system. Complex interactions exist between tipping elements, e.g. physical mechanisms connect subsystems of the climate system. Based on earlier work on such coupled nonlinear systems, we systematically assessed the qualitative long-term behaviour of interacting tipping elements. We developed an understanding of the consequences of interactions\r\non the tipping behaviour allowing for tipping cascades to emerge under certain conditions. The (narrative) application of\r\nthese qualitative results to real-world examples of interacting tipping elements indicates that tipping cascades with profound consequences may occur: the interacting Greenland ice sheet and thermohaline ocean circulation might tip before the tipping points of the isolated subsystems are crossed. The eutrophication of the first lake in a lake chain might propagate through the following lakes without a crossing of their individual critical nutrient input levels. The possibility of emerging cascading tipping dynamics calls for the development of a unified theory of interacting tipping elements and the quantitative analysis of interacting real-world tipping elements.","lang":"eng"}],"pmid":1,"author":[{"last_name":"Klose","first_name":"Ann Kristin","full_name":"Klose, Ann Kristin"},{"last_name":"Karle","full_name":"Karle, Volker","id":"D7C012AE-D7ED-11E9-95E8-1EC5E5697425","orcid":"0000-0002-6963-0129","first_name":"Volker"},{"last_name":"Winkelmann","first_name":"Ricarda","full_name":"Winkelmann, Ricarda"},{"last_name":"Donges","full_name":"Donges, Jonathan F.","first_name":"Jonathan F."}],"ddc":["530","550"],"fulldoi":"https://doi.org/10.1098/rsos.200599","file_date_updated":"2020-11-09T09:07:11Z","doi":"10.1098/rsos.200599","publisher":"The Royal Society","publication_identifier":{"eissn":["2054-5703"]},"day":"01","publication":"Royal Society Open Science","status":"public","_id":"8741","month":"06","year":"2020","article_processing_charge":"No","oa":1,"scopus_import":"1","title":"Emergence of cascading dynamics in interacting tipping elements of ecology and climate: Cascading dynamics in tipping elements"},{"month":"10","_id":"8746","status":"public","year":"2020","publication":"Applied Physics Letters","scopus_import":"1","title":"Electron transport in iodide-capped core@shell PbTe@PbS colloidal nanocrystal solids","article_processing_charge":"No","oa":1,"doi":"10.1063/5.0025965","publisher":"AIP Publishing","fulldoi":"https://doi.org/10.1063/5.0025965","ddc":["530"],"day":"26","publication_identifier":{"eissn":["1077-3118"],"issn":["0003-6951"]},"abstract":[{"lang":"eng","text":"Research in the field of colloidal semiconductor nanocrystals (NCs) has progressed tremendously, mostly because of their exceptional optoelectronic properties. Core@shell NCs, in which one or more inorganic layers overcoat individual NCs, recently received significant attention due to their remarkable optical characteristics. Reduced Auger recombination, suppressed blinking, and enhanced carrier multiplication are among the merits of core@shell NCs. Despite their importance in device development, the influence of the shell and the surface modification of the core@shell NC assemblies on the charge carrier transport remains a pertinent research objective. Type-II PbTe@PbS core@shell NCs, in which exclusive electron transport was demonstrated, still exhibit instability of their electron \r\n ransport. Here, we demonstrate the enhancement of electron transport and stability in PbTe@PbS core@shell NC assemblies using iodide as a surface passivating ligand. The combination of the PbS shelling and the use of the iodide ligand contributes to the addition of one mobile electron for each core@shell NC. Furthermore, both electron mobility and on/off current modulation ratio values of the core@shell NC field-effect transistor are steady with the usage of iodide. Excellent stability in these exclusively electron-transporting core@shell NCs paves the way for their utilization in electronic devices.

Here, a strategy for producing Bi2Te3–Cu2xTe nanocomposites based on the consolidation of heterostructured nanoparticles is described and the thermoelectric properties of the obtained materials are investigated. We first detail a two-step solution-based process to produce Bi2Te3–Cu2xTe heteronanostructures, based on the growth of Cu2xTe nanocrystals on the surface of Bi2Te3 nanowires. We characterize the structural and chemical properties of the synthesized nanostructures and of the nanocomposites\r\nproduced by hot-pressing the particles at moderate temperatures. Besides, the transport properties of the nanocomposites are investigated as a function of the amount of Cu introduced. Overall, the presence of Cu decreases the material thermal conductivity through promotion of phonon scattering, modulates the charge carrier concentration through electron spillover, and increases the Seebeck coefficient through filtering of charge carriers at energy barriers. These effects result in an improvement of over 50% of the thermoelectric figure of merit of Bi2Te3.","lang":"eng"}],"isi":1,"corr_author":"1","article_processing_charge":"No","title":"Bismuth telluride-copper telluride nanocomposites from heterostructured building blocks","scopus_import":"1","publication":"Journal of Materials Chemistry C","year":"2020","status":"public","_id":"8747","month":"10","day":"28","fulldoi":"https://doi.org/10.1039/D0TC02182B","publisher":"Royal Society of Chemistry","doi":"10.1039/D0TC02182B"},{"date_updated":"2025-04-15T06:26:12Z","publication_status":"published","department":[{"_id":"ToHe"}],"language":[{"iso":"eng"}],"date_created":"2020-11-10T07:04:57Z","oa_version":"Preprint","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","quality_controlled":"1","arxiv":1,"type":"conference","date_published":"2020-12-04T00:00:00Z","ec_funded":1,"citation":{"chicago":"Forets, Marcelo, Daniel Freire, and Christian Schilling. “Efficient Reachability Analysis of Parametric Linear Hybrid Systems with Time-Triggered Transitions.” In 18th ACM-IEEE International Conference on Formal Methods and Models for System Design.

Heterogeneity in the concentration of a drug, the quality of breeding sites, or wealth can all affect evolutionary dynamics. In this study, we represent a collection of properties affecting the fitness at a given location using a color. A green node is rich in resources while a red node is poorer. More colors can represent a broader spectrum of resource qualities. For a population evolving according to the birth-death Moran model, the first question we address is which structures, identified by graph connectivity and graph coloring, are evolutionarily equivalent. We prove that all properly two-colored, undirected, regular graphs are evolutionarily equivalent (where “properly colored” means that no two neighbors have the same color). We then compare the effects of background heterogeneity on properly two-colored graphs to those with alternative schemes in which the colors are permuted. Finally, we discuss dynamic coloring as a model for spatiotemporal resource fluctuations, and we illustrate that random dynamic colorings often diminish the effects of background heterogeneity relative to a proper two-coloring.","lang":"eng"}],"author":[{"first_name":"Kamran","full_name":"Kaveh, Kamran","last_name":"Kaveh"},{"full_name":"McAvoy, Alex","first_name":"Alex","last_name":"McAvoy"},{"full_name":"Chatterjee, Krishnendu","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee"},{"full_name":"Nowak, Martin A.","first_name":"Martin A.","last_name":"Nowak"}],"pmid":1,"article_number":"e1008402","isi":1,"keyword":["Ecology","Modelling and Simulation","Computational Theory and Mathematics","Genetics","Ecology","Evolution","Behavior and Systematics","Molecular Biology","Cellular and Molecular Neuroscience"],"year":"2020","_id":"8767","status":"public","month":"11","publication":"PLOS Computational Biology","title":"The Moran process on 2-chromatic graphs","scopus_import":"1","oa":1,"article_processing_charge":"No","publisher":"Public Library of Science","doi":"10.1371/journal.pcbi.1008402","file_date_updated":"2020-11-18T07:26:10Z","ddc":["000"],"fulldoi":"https://doi.org/10.1371/journal.pcbi.1008402","day":"05","publication_identifier":{"issn":["1553-734X"],"eissn":["1553-7358"]}},{"oa":1,"article_processing_charge":"No","title":"Quantum impurity model for anyons","scopus_import":"1","publication":"Physical Review B","year":"2020","status":"public","_id":"8769","month":"10","publication_identifier":{"eissn":["2469-9969"],"issn":["2469-9950"]},"day":"01","fulldoi":"https://doi.org/10.1103/physrevb.102.144109","publisher":"American Physical Society","doi":"10.1103/physrevb.102.144109","author":[{"last_name":"Yakaboylu","first_name":"Enderalp","orcid":"0000-0001-5973-0874","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","full_name":"Yakaboylu, Enderalp"},{"first_name":"Areg","orcid":"0000-0001-9666-3543","full_name":"Ghazaryan, Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","last_name":"Ghazaryan"},{"full_name":"Lundholm, D.","first_name":"D.","last_name":"Lundholm"},{"first_name":"N.","full_name":"Rougerie, N.","last_name":"Rougerie"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802","first_name":"Mikhail","last_name":"Lemeshko"},{"orcid":"0000-0002-6781-0521","first_name":"Robert","full_name":"Seiringer, Robert","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","last_name":"Seiringer"}],"abstract":[{"lang":"eng","text":"One of the hallmarks of quantum statistics, tightly entwined with the concept of topological phases of matter, is the prediction of anyons. Although anyons are predicted to be realized in certain fractional quantum Hall systems, they have not yet been unambiguously detected in experiment. Here we introduce a simple quantum impurity model, where bosonic or fermionic impurities turn into anyons as a consequence of their interaction with the surrounding many-particle bath. A cloud of phonons dresses each impurity in such a way that it effectively attaches fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding quantum impurity model, first, provides a different approach to the numerical solution of the many-anyon problem, along with a concrete perspective of anyons as emergent quasiparticles built from composite bosons or fermions. More importantly, the model paves the way toward realizing anyons using impurities in crystal lattices as well as ultracold gases. In particular, we consider two heavy electrons interacting with a two-dimensional lattice crystal in a magnetic field, and show that when the impurity-bath system is rotated at the cyclotron frequency, impurities behave as anyons as a consequence of the angular momentum exchange between the impurities and the bath. A possible experimental realization is proposed by identifying the statistics parameter in terms of the mean-square distance of the impurities and the magnetization of the impurity-bath system, both of which are accessible to experiment. Another proposed application is impurities immersed in a two-dimensional weakly interacting Bose gas."}],"article_number":"144109","isi":1,"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"Preprint","date_created":"2020-11-18T07:34:17Z","language":[{"iso":"eng"}],"arxiv":1,"intvolume":" 102","quality_controlled":"1","type":"journal_article","date_published":"2020-10-01T00:00:00Z","date_updated":"2025-04-14T07:26:54Z","department":[{"_id":"MiLe"},{"_id":"RoSe"}],"publication_status":"published","article_type":"original","acknowledgement":"We are grateful to M.
