Peroxiredoxins (PRDXs) eliminate reactive oxygen species such as hydrogen peroxide through a catalytic cycle of Cys oxidation and reduction. Additionally, upon Cys oxidation PRDXs undergo extensive conformational rearrangements that may underlie their presently structurally poorly defined functions as molecular chaperones. Rearrangements include high molecular-weight oligomerization, the dynamics of which are, however, poorly understood, as is the impact of disulfide bond formation on these properties. Here we show that formation of disulfide bonds along the catalytic cycle induces extensive microsecond time scale dynamics, as monitored by magic-angle spinning NMR of the 216 kDa-large Tsa1 decameric assembly and solution-NMR of a designed dimeric mutant. We ascribe the conformational dynamics to structural frustration, resulting from conflicts between the disulfide-constrained reduction of mobility and the desire to fulfil other favorable contacts. \r\n\r\nThis data repository contains NMR data presented in the associated manuscript","lang":"eng"}],"related_material":{"record":[{"id":"13095","status":"public","relation":"used_in_publication"}]},"has_accepted_license":"1","date_published":"2023-04-18T00:00:00Z","date_updated":"2023-08-01T14:48:08Z","day":"18","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Research data of the publication \"Disulfide-bond-induced structural frustration and dynamic disorder in a peroxiredoxin from MAS NMR\"","department":[{"_id":"PaSc"}],"month":"04","year":"2023","contributor":[{"last_name":"Troussicot","contributor_type":"researcher","first_name":"Laura"},{"last_name":"Burmann","first_name":"Björn M.","contributor_type":"researcher"}],"citation":{"ama":"Schanda P.

In contrast with passive gears, whose function is to transmit torques from one to another, interlocking and untethered active gears have the potential to unveil dynamics and functions untapped by externally driven mechanisms. Here, it is shown the assembly and control of a family of self-spinning cogwheels with varying teeth numbers and study the interlocking of multiple cogwheels. The teeth are formed by colloidal microswimmers that power the structure. The cogwheels are autonomous and active, showing persistent rotation. Leveraging the angular momentum of optical vortices, we control the direction of rotation of the cogwheels. The pairs of interlocking and active cogwheels that roll over each other in a random walk and have curvature-dependent mobility are studied. This behavior is leveraged to self-position parts and program microbots, demonstrating the ability to pick up, direct, and release a load.

These computations require a panoramic assessment of the visual environment in order to disambiguate similar sensory experiences that may require distinct behavioral responses. The estimation of the global motion patterns is therefore essential for successful navigation. Yet, our understanding of the algorithms and implementations that enable coherent panoramic visual perception remains scarce. Here I pursue this problem by dissecting the functional aspects of interneuronal communication in the lobula plate tangential cell network in Drosophila melanogaster. The results presented in the thesis demonstrate that the basis for effective interpretation of the optic flow in this circuit are stereotyped synaptic connections that mediate the formation of distinct subnetworks, each extracting a particular pattern of global motion. \r\nFirstly, I show that gap junctions are essential for a correct interpretation of binocular motion cues by horizontal motion-sensitive cells. HS cells form electrical synapses with contralateral H2 neurons that are involved in detecting yaw rotation and translation. I developed an FlpStop-mediated mutant of a gap junction protein ShakB that disrupts these electrical synapses. While the loss of electrical synapses does not affect the tuning of the direction selectivity in HS neurons, it severely alters their sensitivity to horizontal motion in the contralateral side. These physiological changes result in an inappropriate integration of binocular motion cues in walking animals. While wild-type flies form a binocular perception of visual motion by non-linear integration of monocular optic flow cues, the mutant flies sum the monocular inputs linearly. These results indicate that rather than averaging signals in neighboring neurons, gap-junctions operate in conjunction with chemical synapses to mediate complex non-linear optic flow computations.\r\nSecondly, I show that stochastic manipulation of neuronal activity in the lobula plate tangential cell network is a powerful approach to study the neuronal implementation of optic flow-based navigation in flies. Tangential neurons form multiple subnetworks, each mediating course-stabilizing response to a particular global pattern of visual motion. Application of genetic mosaic techniques can provide sparse optogenetic activation of HS cells in numerous combinations. These distinct combinations of activated neurons drive an array of distinct behavioral responses, providing important insights into how visuomotor transformation is performed in the lobula plate tangential cell network. This approach can be complemented by stochastic silencing of tangential neurons, enabling direct assessment of the functional role of individual tangential neurons in the processing of specific visual motion patterns.\r\n\tTaken together, the findings presented in this thesis suggest that establishing specific activity patterns of tangential cells via stereotyped synaptic connectivity is a key to efficient optic flow-based navigation in Drosophila melanogaster.","lang":"eng"}],"language":[{"iso":"eng"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2023-06-23T09:47:36Z","author":[{"first_name":"Victoria","id":"3184041C-F248-11E8-B48F-1D18A9856A87","last_name":"Pokusaeva","full_name":"Pokusaeva, Victoria","orcid":"0000-0001-7660-444X"}],"status":"public","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"citation":{"apa":"Pokusaeva, V.

Herein, we detail a colloidal synthesis route for the incorporation of P on Pd2Sn nanoparticles. These nanoparticles are dispersed on carbon black and the obtained composite is used as electrocatalytic material for the FOR. The Pd2Sn0.8P-based electrodes present outstanding catalytic activities with record mass current densities up to 10.0 A mgPd-1, well above those of Pd1.6Sn/C reference electrode. These high current densities are further enhanced by increasing the temperature from 25 °C to 40 °C. The Pd2Sn0.8P electrode also allows for slowing down the rapid current decay that generally happens during operation and can be rapidly re-activated through potential cycling.

This IF relocalization, in turn, facilitates ppl cell protrusion formation and migration by opening up the space into which the ppl moves and, thereby, the ability of the ppl to trigger IF relocalization by pushing against the overlying deep cell layer. Thus, embryonic axis formation relies on a hydraulic feedback loop between cell migration and IF relocalization."}],"scopus_import":"1","date_updated":"2023-08-01T14:10:38Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"department":[{"_id":"CaHe"},{"_id":"Bio"}],"article_type":"original","publication_identifier":{"issn":["1534-5807"],"eissn":["1878-1551"]},"isi":1,"project":[{"grant_number":"742573","call_identifier":"H2020","name":"Interaction and feedback between cell mechanics and fate specification in vertebrate gastrulation","_id":"260F1432-B435-11E9-9278-68D0E5697425"},{"grant_number":"ALTF 850-2017","_id":"26520D1E-B435-11E9-9278-68D0E5697425","name":"Coordination of mesendoderm cell fate specification and internalization during zebrafish gastrulation"},{"grant_number":"LT000429","name":"Coordination of mesendoderm fate specification and internalization during zebrafish gastrulation","_id":"266BC5CE-B435-11E9-9278-68D0E5697425"}],"month":"04","year":"2023","ddc":["570"],"file":[{"access_level":"open_access","content_type":"application/pdf","date_updated":"2023-04-17T07:41:25Z","file_size":7925886,"checksum":"c80ca2ebc241232aacdb5aa4b4c80957","success":1,"date_created":"2023-04-17T07:41:25Z","file_name":"2023_DevelopmentalCell_Huljev.pdf","file_id":"12842","creator":"dernst","relation":"main_file"}],"oa_version":"Published Version","type":"journal_article","external_id":{"isi":["000982111800001"]},"publication_status":"published","issue":"7","_id":"12830","publisher":"Elsevier"},{"article_type":"original","department":[{"_id":"MiLe"}],"project":[{"grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle"}],"year":"2023","month":"04","publication_identifier":{"eissn":["1089-7690"]},"isi":1,"external_id":{"arxiv":["2211.08070"],"isi":["000970038800001"]},"publication_status":"published","_id":"12831","issue":"13","file":[{"file_name":"2023_JourChemicalPhysics_Zeng.pdf","creator":"dernst","file_id":"12841","relation":"main_file","content_type":"application/pdf","access_level":"open_access","date_updated":"2023-04-17T07:28:38Z","checksum":"8d801babea4df48e08895c76571bb19e","success":1,"file_size":7388057,"date_created":"2023-04-17T07:28:38Z"}],"type":"journal_article","ddc":["530"],"oa_version":"Published Version","publisher":"American Institute of Physics","status":"public","author":[{"full_name":"Zeng, Zhongda","last_name":"Zeng","first_name":"Zhongda"},{"orcid":"0000-0001-5973-0874","last_name":"Yakaboylu","full_name":"Yakaboylu, Enderalp","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","first_name":"Enderalp"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","last_name":"Lemeshko","full_name":"Lemeshko, Mikhail","orcid":"0000-0002-6990-7802"},{"first_name":"Tao","last_name":"Shi","full_name":"Shi, Tao"},{"full_name":"Schmidt, Richard","last_name":"Schmidt","first_name":"Richard"}],"scopus_import":"1","abstract":[{"lang":"eng","text":"The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations of a many-body bath, can be used to describe an impurity rotating in a fluid or solid environment. Here, we propose a coherent state ansatz in the co-rotating frame, which provides a comprehensive theoretical description of angulons. We reveal the quasiparticle properties, such as energies, quasiparticle weights, and spectral functions, and show that our ansatz yields a persistent decrease in the impurity’s rotational constant due to many-body dressing, which is consistent with experimental observations. From our study, a picture of the angulon emerges as an effective spin interacting with a magnetic field that is self-consistently generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy, which focuses on the response of rotating molecules to a laser perturbation in the linear response regime. Importantly, we take into account initial-state interactions that have been neglected in prior studies and reveal their impact on the excitation spectrum. To examine the angulon instability regime, we use a single-excitation ansatz and obtain results consistent with experiments, in which a broadening of spectral lines is observed while phonon wings remain highly suppressed due to initial-state interactions."}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"date_updated":"2023-08-01T14:08:47Z","title":"Variational theory of angulons and their rotational spectroscopy","quality_controlled":"1","arxiv":1,"citation":{"ama":"Zeng Z, Yakaboylu E, Lemeshko M, Shi T, Schmidt R.

Such catalysts must contain multiple adsorption/reaction sites to cope with the high demands of reversible oxygen electrodes. Herein, we propose a high entropy alloy (HEA) based on relatively abundant elements as a bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays superior OER performance with an overpotential of 265 mV at a current density of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard commercial catalyst based on RuO2. This high performance is partially explained by the presence of twinned defects, the incidence of large lattice distortions, and the electronic synergy between the different components, being Cr key to decreasing the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays superior ORR performance with a half-potential of 0.78 V and an onset potential of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi HEA as air cathode and a zinc foil as the anode. The assembled cells provide an open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8 mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"date_updated":"2023-08-01T14:08:02Z","status":"public","author":[{"last_name":"He","full_name":"He, Ren","first_name":"Ren"},{"first_name":"Linlin","full_name":"Yang, Linlin","last_name":"Yang"},{"first_name":"Yu","full_name":"Zhang, Yu","last_name":"Zhang"},{"first_name":"Xiang","last_name":"Wang","full_name":"Wang, Xiang"},{"first_name":"Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425","full_name":"Lee, Seungho","last_name":"Lee","orcid":"0000-0002-6962-8598"},{"last_name":"Zhang","full_name":"Zhang, Ting","first_name":"Ting"},{"full_name":"Li, Lingxiao","last_name":"Li","first_name":"Lingxiao"},{"first_name":"Zhifu","full_name":"Liang, Zhifu","last_name":"Liang"},{"first_name":"Jingwei","full_name":"Chen, Jingwei","last_name":"Chen"},{"last_name":"Li","full_name":"Li, Junshan","first_name":"Junshan"},{"first_name":"Ahmad","full_name":"Ostovari Moghaddam, Ahmad","last_name":"Ostovari Moghaddam"},{"first_name":"Jordi","last_name":"Llorca","full_name":"Llorca, Jordi"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","orcid":"0000-0001-5013-2843","last_name":"Ibáñez","full_name":"Ibáñez, Maria"},{"first_name":"Jordi","full_name":"Arbiol, Jordi","last_name":"Arbiol"},{"full_name":"Xu, Ying","last_name":"Xu","first_name":"Ying"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}]},{"doi":"10.46298/DMTCS.8383","file_date_updated":"2023-04-17T08:10:28Z","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_processing_charge":"No","day":"18","publication":"Discrete Mathematics and Theoretical Computer Science","acknowledgement":"This work was begun at the University of Waterloo and was partially supported by the Natural Sciences and Engineering Council of Canada (NSERC).\r\n","volume":24,"intvolume":"        24","has_accepted_license":"1","date_published":"2023-01-18T00:00:00Z","title":"Token swapping on trees","oa":1,"article_number":"9","citation":{"chicago":"Biniaz, Ahmad, Kshitij Jain, Anna Lubiw, Zuzana Masárová, Tillmann Miltzow, Debajyoti Mondal, Anurag Murty Naredla, Josef Tkadlec, and Alexi Turcotte. “Token Swapping on Trees.” <i>Discrete Mathematics and Theoretical Computer Science</i>.

The goal is to get token i to vertex vi for all i= 1, . . . , n using a minimum number of swaps, where a swap exchanges the tokens on the endpoints of an edge.Token swapping on a tree, also known as “sorting with a transposition tree,” is not known to be in P nor NP-complete. We present some partial results: 1. An optimum swap sequence may need to perform a swap on a leaf vertex that has the correct token (a “happy leaf”), disproving a conjecture of Vaughan. 2. Any algorithm that fixes happy leaves—as all known approximation algorithms for the problem do—has approximation factor at least 4/3. Furthermore, the two best-known 2-approximation algorithms have approximation factor exactly 2. 3. A generalized problem—weighted coloured token swapping—is NP-complete on trees, but solvable in polynomial time on paths and stars. In this version, tokens and vertices have colours, and colours have weights. The goal is to get every token to a vertex of the same colour, and the cost of a swap is the sum of the weights of the two tokens involved.","lang":"eng"}],"scopus_import":"1","publication_identifier":{"issn":["1462-7264"],"eissn":["1365-8050"]},"year":"2023","month":"01","department":[{"_id":"KrCh"},{"_id":"HeEd"},{"_id":"UlWa"}],"article_type":"original","publisher":"EPI Sciences","ddc":["000"],"type":"journal_article","file":[{"file_name":"2022_DMTCS_Biniaz.pdf","file_id":"12844","creator":"dernst","relation":"main_file","access_level":"open_access","content_type":"application/pdf","date_updated":"2023-04-17T08:10:28Z","file_size":2072197,"success":1,"checksum":"439102ea4f6e2aeefd7107dfb9ccf532","date_created":"2023-04-17T08:10:28Z"}],"oa_version":"Published Version","publication_status":"published","external_id":{"arxiv":["1903.06981"]},"issue":"2","_id":"12833"},{"department":[{"_id":"MiLe"}],"article_type":"original","isi":1,"publication_identifier":{"eissn":["2195-1071"]},"year":"2023","month":"07","oa_version":"Preprint","type":"journal_article","_id":"12836","issue":"13","publication_status":"published","external_id":{"arxiv":["2211.08755"],"isi":["000963866700001"]},"publisher":"Wiley","author":[{"full_name":"Khatoniar, Mandeep","last_name":"Khatoniar","first_name":"Mandeep"},{"first_name":"Nicholas","last_name":"Yama","full_name":"Yama, Nicholas"},{"first_name":"Areg","id":"4AF46FD6-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9666-3543","full_name":"Ghazaryan, Areg","last_name":"Ghazaryan"},{"first_name":"Sriram","full_name":"Guddala, Sriram","last_name":"Guddala"},{"full_name":"Ghaemi, Pouyan","last_name":"Ghaemi","first_name":"Pouyan"},{"first_name":"Kausik","full_name":"Majumdar, Kausik","last_name":"Majumdar"},{"last_name":"Menon","full_name":"Menon, Vinod","first_name":"Vinod"}],"status":"public","abstract":[{"text":"Coherent control and manipulation of quantum degrees of freedom such as spins forms the basis of emerging quantum technologies. In this context, the robust valley degree of freedom and the associated valley pseudospin found in two-dimensional transition metal dichalcogenides is a highly attractive platform. Valley polarization and coherent superposition of valley states have been observed in these systems even up to room temperature. Control of valley coherence is an important building block for the implementation of valley qubit. Large magnetic fields or high-power lasers have been used in the past to demonstrate the control (initialization and rotation) of the valley coherent states. Here, the control of layer–valley coherence via strong coupling of valley excitons in bilayer WS2 to microcavity photons is demonstrated by exploiting the pseudomagnetic field arising in optical cavities owing to the transverse electric–transverse magnetic (TE–TM)mode splitting. The use of photonic structures to generate pseudomagnetic fields which can be used to manipulate exciton-polaritons presents an attractive approach to control optical responses without the need for large magnets or high-intensity optical pump powers.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2211.08755"}],"scopus_import":"1","date_updated":"2023-10-04T11:15:17Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"title":"Optical manipulation of Layer–Valley coherence via strong exciton–photon coupling in microcavities","citation":{"mla":"Khatoniar, Mandeep, et al. “Optical Manipulation of Layer–Valley Coherence via Strong Exciton–Photon Coupling in Microcavities.” <i>Advanced Optical Materials</i>, vol. 11, no. 13, 2202631, Wiley, 2023, doi:<a href=\"https://doi.org/10.1002/adom.202202631\">10.1002/adom.202202631</a>.","apa":"Khatoniar, M., Yama, N., Ghazaryan, A., Guddala, S., Ghaemi, P., Majumdar, K., &#38; Menon, V.

Such changes result from tension dynamics at cell contacts or cellular jamming. Yet, in many cases, the cellular mechanisms controlling the physical state of growing tissues are unclear. We found that at early developmental stages, the epithelium in the developing mouse spinal cord maintains both high junctional tension and high fluidity. This is achieved via a mechanism in which interkinetic nuclear movements generate cell area dynamics that drive extensive cell rearrangements. Over time, the cell proliferation rate declines, effectively solidifying the tissue. Thus, unlike well-studied jamming transitions, the solidification uncovered here resembles a glass transition that depends on the dynamical stresses generated by proliferation and differentiation. Our finding that the fluidity of developing epithelia is linked to interkinetic nuclear movements and the dynamics of growth is likely to be relevant to multiple developing tissues."}],"scopus_import":"1"},{"date_created":"2023-04-16T22:01:09Z","citation":{"ama":"Zhang Y, Vatedka S.

A multiple packing is a set C of points in R n such that any point in R n lies in the intersection of at most L – 1 balls of radius √ nN around points in C . Given a well-known connection with coding theory, multiple packings can be viewed as the Euclidean analog of list-decodable codes, which are well-studied for finite fields. In this paper, we derive the best known lower bounds on the optimal density of list-decodable infinite constellations for constant L under a stronger notion called average-radius multiple packing.

Here, we study infinite-temperature energy transport in the kinetically constrained PXP model describing Rydberg atom quantum simulators. Our state-of-the-art numerical simulations, including exact diagonalization and time-evolving block decimation methods, reveal the existence of two distinct transport regimes. At moderate times, the energy-energy correlation function displays periodic oscillations due to families of eigenstates forming different su(2) representations hidden within the spectrum. These families of eigenstates generalize the quantum many-body scarred states found in previous works and leave an imprint on the infinite-temperature energy transport. At later times, we observe a long-lived superdiffusive transport regime that we attribute to the proximity of a nearby integrable point. While generic strong deformations of the PXP model indeed restore diffusive transport, adding a strong chemical potential intriguingly gives rise to a well-converged superdiffusive exponent z≈3/2. Our results suggest constrained models to be potential hosts of novel transport regimes and call for developing an analytic understanding of their energy transport.","lang":"eng"}],"scopus_import":"1","date_updated":"2023-08-01T14:11:28Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}]},{"project":[{"_id":"34bc2376-11ca-11ed-8bc3-9a3b3961a088","name":"Computational Discovery of Numerical Algorithms for Animation and Simulation of Natural Phenomena","grant_number":"101045083"}],"year":"2023","month":"03","department":[{"_id":"GradSch"},{"_id":"ChWo"}],"title":"Area formula for spherical polygons via prequantization","oa":1,"article_number":"2303.14555","arxiv":1,"external_id":{"arxiv":["2303.14555"]},"publication_status":"submitted","_id":"12846","type":"preprint","oa_version":"Preprint","citation":{"short":"A.

Third-party monitoring, with limited knowledge of the monitored software, and best-effort monitoring, which keeps pace with the monitored software, are especially valuable, yet underexplored areas of run-time monitoring. Most existing monitoring frameworks do not support their combination because they either require access to the monitored code for instrumentation purposes or the processing of all observed events, or both.\r\n\r\nWe present a middleware framework, VAMOS, for the run-time monitoring of software which is explicitly designed to support third-party and best-effort scenarios. The design goals of VAMOS are (i) efficiency (keeping pace at low overhead), (ii) flexibility (the ability to monitor black-box code through a variety of different event channels, and the connectability to monitors written in different specification languages), and (iii) ease-of-use. To achieve its goals, VAMOS combines aspects of event broker and event recognition systems with aspects of stream processing systems.\r\nWe implemented a prototype toolchain for VAMOS and conducted experiments including a case study of monitoring for data races.

In this paper, we address these gaps by focusing on empirical risk minimization in two prototypical settings, namely, random features and the neural tangent kernel (NTK). We prove that, for random features, the model is not robust for any degree of over-parameterization, even when the necessary condition coming from the universal law of robustness is satisfied. In contrast, for even activations, the NTK model meets the universal lower bound, and it is robust as soon as the necessary condition on over-parameterization is fulfilled. This also addresses a conjecture in prior work by Bubeck, Li and Nagaraj. Our analysis decouples the effect of the kernel of the model from an \"interaction matrix\", which describes the interaction with the test data and captures the effect of the activation. Our theoretical results are corroborated by numerical evidence on both synthetic and standard datasets (MNIST, CIFAR-10).","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2302.01629"}],"related_material":{"link":[{"url":"https://github.com/simone-bombari/beyond-universal-robustness","relation":"software"}]},"author":[{"first_name":"Simone","id":"ca726dda-de17-11ea-bc14-f9da834f63aa","full_name":"Bombari, Simone","last_name":"Bombari"},{"first_name":"Shayan","id":"f5a2b424-e339-11ed-8435-ff3b4fe70cf8","last_name":"Kiyani","full_name":"Kiyani, Shayan"},{"first_name":"Marco","id":"27EB676C-8706-11E9-9510-7717E6697425","last_name":"Mondelli","full_name":"Mondelli, Marco","orcid":"0000-0002-3242-7020"}],"status":"public","publisher":"ML Research Press","oa_version":"Preprint","type":"conference","_id":"12859","external_id":{"arxiv":["2302.01629"]},"publication_status":"published","alternative_title":["PMLR"],"month":"10","year":"2023","project":[{"_id":"059876FA-7A3F-11EA-A408-12923DDC885E","name":"Prix Lopez-Loretta 2019 - Marco Mondelli"}],"department":[{"_id":"GradSch"},{"_id":"MaMo"}],"volume":202,"publication":"Proceedings of the 40th International Conference on Machine Learning","acknowledgement":"Simone Bombari and Marco Mondelli were partially supported by the 2019 Lopez-Loreta prize, and\r\nthe authors would like to thank Hamed Hassani for helpful discussions.\r\n","day":"27","intvolume":"       202","date_published":"2023-10-27T00:00:00Z","article_processing_charge":"No","oa":1,"date_created":"2023-04-23T16:11:03Z","citation":{"ista":"Bombari S, Kiyani S, Mondelli M. 2023.

By adhering to certain social norms, cooperating individuals can improve their reputation and, in turn, receive benefits from others. Eight social norms, known as the “leading eight,\" have been shown to effectively promote the evolution of cooperation as long as information is public and reliable. These norms categorize group members as either ’good’ or ’bad’. In this study, we examine a scenario where individuals instead assign nuanced reputation scores to each other, and only cooperate with those whose reputation exceeds a certain threshold. We find both analytically and through simulations that such quantitative assessments are error-correcting, thus facilitating cooperation in situations where information is private and unreliable. Moreover, our results identify four specific norms that are robust to such conditions, and may be relevant for helping to sustain cooperation in natural populations."}],"status":"public","author":[{"orcid":"0000-0002-6978-7329","full_name":"Schmid, Laura","last_name":"Schmid","first_name":"Laura","id":"38B437DE-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Farbod","last_name":"Ekbatani","full_name":"Ekbatani, Farbod"},{"first_name":"Christian","id":"2FDF8F3C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5116-955X","full_name":"Hilbe, Christian","last_name":"Hilbe"},{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","last_name":"Chatterjee","full_name":"Chatterjee, Krishnendu"}],"publisher":"Springer Nature","external_id":{"isi":["001003644100020"],"pmid":["37045828"]},"publication_status":"published","_id":"12861","type":"journal_article","file":[{"file_id":"12868","creator":"dernst","relation":"main_file","file_name":"2023_NatureComm_Schmid.pdf","checksum":"a4b3b7b36fbef068cabf4fb99501fef6","file_size":1786475,"success":1,"date_created":"2023-04-25T09:13:53Z","access_level":"open_access","content_type":"application/pdf","date_updated":"2023-04-25T09:13:53Z"}],"oa_version":"Published Version","ddc":["000"],"project":[{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818"},{"grant_number":"Z211","_id":"25F42A32-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"The Wittgenstein Prize"}],"month":"04","year":"2023","publication_identifier":{"eissn":["2041-1723"]},"isi":1,"article_type":"original","department":[{"_id":"KrCh"}],"pmid":1,"acknowledgement":"This work was supported by the European Research Council CoG 863818 (ForM-SMArt) (to K.C.) and the European Research Council Starting Grant 850529: E-DIRECT (to C.H.).

One obstacle is the difficulty to link high dimensional functional connectivity measures to mechanistic models of network activity. We address this issue by investigating spike-field coupling (SFC) measurements, which quantify the synchronization between, on the one hand, the action potentials produced by neurons, and on the other hand mesoscopic “field” signals, reflecting subthreshold activities at possibly multiple recording sites. As the number of recording sites gets large, the amount of pairwise SFC measurements becomes overwhelmingly challenging to interpret. We develop Generalized Phase Locking Analysis (GPLA) as an interpretable dimensionality reduction of this multivariate SFC. GPLA describes the dominant coupling between field activity and neural ensembles across space and frequencies. We show that GPLA features are biophysically interpretable when used in conjunction with appropriate network models, such that we can identify the influence of underlying circuit properties on these features. We demonstrate the statistical benefits and interpretability of this approach in various computational models and Utah array recordings. The results suggest that GPLA, used jointly with biophysical modeling, can help uncover the contribution of recurrent microcircuits to the spatio-temporal dynamics observed in multi-channel experimental recordings."}],"scopus_import":"1","date_updated":"2023-08-01T14:15:16Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","language":[{"iso":"eng"}],"status":"public","author":[{"first_name":"Shervin","last_name":"Safavi","full_name":"Safavi, Shervin"},{"full_name":"Panagiotaropoulos, Theofanis I.","last_name":"Panagiotaropoulos","first_name":"Theofanis I."},{"full_name":"Kapoor, Vishal","last_name":"Kapoor","first_name":"Vishal"},{"id":"44B06F76-F248-11E8-B48F-1D18A9856A87","first_name":"Juan F","full_name":"Ramirez Villegas, Juan F","last_name":"Ramirez Villegas"},{"full_name":"Logothetis, Nikos K.","last_name":"Logothetis","first_name":"Nikos K."},{"first_name":"Michel","full_name":"Besserve, Michel","last_name":"Besserve"}],"type":"journal_article","oa_version":"Published Version","file":[{"date_updated":"2023-04-25T08:59:18Z","content_type":"application/pdf","access_level":"open_access","date_created":"2023-04-25T08:59:18Z","success":1,"file_size":4737671,"checksum":"edeb9d09f3e41ba7c0251308b9e372e7","file_name":"2023_PLoSCompBio_Safavi.pdf","relation":"main_file","creator":"dernst","file_id":"12867"}],"ddc":["570"],"publication_status":"published","external_id":{"isi":["000962668700002"]},"_id":"12862","issue":"4","publisher":"Public Library of Science","department":[{"_id":"JoCs"}],"article_type":"original","publication_identifier":{"eissn":["1553-7358"]},"isi":1,"month":"04","year":"2023","has_accepted_license":"1","intvolume":"        19","date_published":"2023-04-01T00:00:00Z","acknowledgement":"We thank Britni Crocker for help with preprocessing of the data and spike sorting; Joachim Werner and Michael Schnabel for their excellent IT support; Andreas Tolias for help with the initial implantation’s of the Utah arrays.\r\nAll authors were supported by the Max Planck Society.

The model can be conceptualized as a game where the expansion rate of cultures is quantified in terms of their area and perimeter in such a way that approximately round cultures get a competitive advantage.  We first analyse the model  with periodic boundary conditions, where we study how the model can end up in a fixed state, i.e. freezes. Then we implement the model on the European geography with mountains and rivers. We see how the model reproduces some qualitative features of European culture formation, namely that rivers and mountains are more frequently borders between cultures, mountainous regions tend to have higher cultural diversity and the central European plain has less clear cultural borders.
