From that perspective, chiral molecules acting as efficient spin selectors pose a puzzle that attracted a lot of attention in recent years. Here, we revisit the physical origins of chiral-induced spin selectivity (CISS) and propose a simple analytic minimal model to describe it. The model treats a chiral molecule as an anisotropic wire with molecular dipole moments aligned arbitrarily with respect to the wire’s axes and is therefore quite general. Importantly, it shows that the helical structure of the molecule is not necessary to observe CISS and other chiral nonhelical molecules can also be considered as potential candidates for the CISS effect. We also show that the suggested simple model captures the main characteristics of CISS observed in the experiment, without the need for additional constraints employed in the previous studies. The results pave the way for understanding other related physical phenomena where the CISS effect plays an essential role."}],"quality_controlled":"1","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"oa":1,"date_published":"2020-05-04T00:00:00Z","year":"2020","issue":"21","citation":{"ama":"Ghazaryan A, Paltiel Y, Lemeshko M.

In particular, the emergence of the new multiple Dirac points in ABA stacked trilayer graphene subject to strong transverse electric fields was proposed theoretically and confirmed experimentally. These new Dirac points dubbed “gullies” emerge from the interplay between strong electric field and trigonal warping. In this work, we first characterize the properties of new emergent Dirac points and show that the electric field can be used to tune the distance between gullies in the momentum space. We demonstrate that the band structure has multiple Lifshitz transitions and higher-order singularity of “monkey saddle” type. Following the characterization of the band structure, we consider the spectrum of Landau levels and structure of their wave functions. In the limit of strong electric fields when gullies are well separated in momentum space, they give rise to triply degenerate Landau levels. In the second part of this work, we investigate how degeneracy between three gully Landau levels is lifted in the presence of interactions. Within the Hartree-Fock approximation we show that the symmetry breaking state interpolates between the fully gully polarized state that breaks C3  symmetry at high displacement field and the gully symmetric state when the electric field is decreased. The discontinuous transition between these two states is driven by enhanced intergully tunneling and exchange. We conclude by outlining specific experimental predictions for the existence of such a symmetry-breaking state.","lang":"eng"}],"intvolume":"       101","date_created":"2020-06-17T14:52:06Z","quality_controlled":"1","oa":1,"date_published":"2020-06-15T00:00:00Z","issue":"24","year":"2020","article_number":"245411","citation":{"mla":"Rao, Peng, and Maksym Serbyn. “Gully Quantum Hall Ferromagnetism in Biased Trilayer Graphene.” <i>Physical Review B</i>, vol. 101, no. 24, 245411, American Physical Society, 2020, doi:<a href=\"https://doi.org/10.1103/physrevb.101.245411\">10.1103/physrevb.101.245411</a>.","ieee":"P.

Batteries are vital to this endeavor, whether used in electric vehicles, to store renewable electricity, or in aviation. Present lithium-ion technologies are preparing the public for this inevitable change, but their maximum theoretical specific capacity presents a limitation. Their high cost is another concern for commercial viability. Metal–air batteries have the highest theoretical energy density of all possible secondary battery technologies and could yield step changes in energy storage, if their practical difficulties could be overcome. The scope of this review is to provide an objective, comprehensive, and authoritative assessment of the intensive work invested in nonaqueous rechargeable metal–air batteries over the past few years, which identified the key problems and guides directions to solve them. We focus primarily on the challenges and outlook for Li–O2 cells but include Na–O2, K–O2, and Mg–O2 cells for comparison. Our review highlights the interdisciplinary nature of this field that involves a combination of materials chemistry, electrochemistry, computation, microscopy, spectroscopy, and surface science. The mechanisms of O2 reduction and evolution are considered in the light of recent findings, along with developments in positive and negative electrodes, electrolytes, electrocatalysis on surfaces and in solution, and the degradative effect of singlet oxygen, which is typically formed in Li–O2 cells."}],"intvolume":"       120","date_created":"2020-06-19T08:42:47Z","quality_controlled":"1","date_published":"2020-03-05T00:00:00Z","issue":"14","year":"2020","oa":1,"_id":"7985","day":"05","publisher":"American Chemical Society","ddc":["540"],"pmid":1,"publication":"Chemical Reviews","volume":120,"article_type":"review","title":"Lithium-oxygen batteries and related systems: Potential, status, and future"},{"status":"public","doi":"10.4230/LIPIcs.SoCG.2020.61","publication_status":"published","oa_version":"Published Version","type":"conference","article_processing_charge":"No","author":[{"last_name":"Patakova","full_name":"Patakova, Zuzana","first_name":"Zuzana","orcid":"0000-0002-3975-1683","id":"48B57058-F248-11E8-B48F-1D18A9856A87"}],"date_updated":"2025-07-10T11:54:54Z","department":[{"_id":"UlWa"}],"article_number":"61:1-61:13","has_accepted_license":"1","citation":{"ista":"Patakova Z. 2020.

Combined with a recent result of Holmsen and Lee, it gives fractional Helly theorem, and consequently the existence of weak ε-nets as well as a (p,q)-theorem. More precisely: Let X be either ℝ^d, smooth real d-manifold, or a finite d-dimensional simplicial complex. Then if F is a finite, intersection-closed family of sets in X such that the ith reduced Betti number (with ℤ₂ coefficients) of any set in F is at most b for every non-negative integer i less or equal to k, then the Radon number of F is bounded in terms of b and X. Here k is the smallest integer larger or equal to d/2 - 1 if X = ℝ^d; k=d-1 if X is a smooth real d-manifold and not a surface, k=0 if X is a surface and k=d if X is a d-dimensional simplicial complex. Using the recent result of the author and Kalai, we manage to prove the following optimal bound on fractional Helly number for families of open sets in a surface: Let F be a finite family of open sets in a surface S such that the intersection of any subfamily of F is either empty, or path-connected. Then the fractional Helly number of F is at most three. This also settles a conjecture of Holmsen, Kim, and Lee about an existence of a (p,q)-theorem for open subsets of a surface.","lang":"eng"}],"quality_controlled":"1","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"oa":1,"date_published":"2020-06-01T00:00:00Z","alternative_title":["LIPIcs"],"year":"2020","ddc":["510"],"_id":"7989","day":"01","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","arxiv":1,"volume":164,"title":"Bounding radon number via Betti numbers","publication":"36th International Symposium on Computational Geometry"},{"date_updated":"2025-07-10T11:54:56Z","department":[{"_id":"UlWa"}],"author":[{"first_name":"Uli","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1494-0568","full_name":"Wagner, Uli","last_name":"Wagner"},{"first_name":"Emo","full_name":"Welzl, Emo","last_name":"Welzl"}],"article_processing_charge":"No","doi":"10.4230/LIPIcs.SoCG.2020.67","publication_status":"published","oa_version":"Published Version","type":"conference","status":"public","external_id":{"arxiv":["2003.13557"]},"file":[{"date_updated":"2020-07-14T12:48:06Z","file_name":"2020_LIPIcsSoCG_Wagner.pdf","file_size":793187,"relation":"main_file","checksum":"3f6925be5f3dcdb3b14cab92f410edf7","access_level":"open_access","date_created":"2020-06-23T06:37:27Z","file_id":"8003","creator":"dernst","content_type":"application/pdf"}],"related_material":{"record":[{"status":"public","relation":"later_version","id":"12129"}]},"publication_identifier":{"isbn":["9783959771436"],"issn":["1868-8969"]},"conference":{"end_date":"2020-06-26","name":"SoCG: Symposium on Computational Geometry","start_date":"2020-06-22","location":"Zürich, Switzerland"},"month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","scopus_import":"1","file_date_updated":"2020-07-14T12:48:06Z","corr_author":"1","article_number":"67:1 - 67:16","has_accepted_license":"1","citation":{"chicago":"Wagner, Uli, and Emo Welzl. “Connectivity of Triangulation Flip Graphs in the Plane (Part II: Bistellar Flips).” In <i>36th International Symposium on Computational Geometry</i>, Vol. 164.

A partial triangulation on P is a full triangulation of some subset P' of P containing all extreme points in P. A bistellar flip on a partial triangulation either flips an edge, removes a non-extreme point of degree 3, or adds a point in P ⧵ P' as vertex of degree 3. The bistellar flip graph has all partial triangulations as vertices, and a pair of partial triangulations is adjacent if they can be obtained from one another by a bistellar flip. The goal of this paper is to investigate the structure of this graph, with emphasis on its connectivity. For sets P of n points in general position, we show that the bistellar flip graph is (n-3)-connected, thereby answering, for sets in general position, an open questions raised in a book (by De Loera, Rambau, and Santos) and a survey (by Lee and Santos) on triangulations. This matches the situation for the subfamily of regular triangulations (i.e., partial triangulations obtained by lifting the points and projecting the lower convex hull), where (n-3)-connectivity has been known since the late 1980s through the secondary polytope (Gelfand, Kapranov, Zelevinsky) and Balinski’s Theorem. Our methods also yield the following results (see the full version [Wagner and Welzl, 2020]): (i) The bistellar flip graph can be covered by graphs of polytopes of dimension n-3 (products of secondary polytopes). (ii) A partial triangulation is regular, if it has distance n-3 in the Hasse diagram of the partial order of partial subdivisions from the trivial subdivision. (iii) All partial triangulations are regular iff the trivial subdivision has height n-3 in the partial order of partial subdivisions. (iv) There are arbitrarily large sets P with non-regular partial triangulations, while every proper subset has only regular triangulations, i.e., there are no small certificates for the existence of non-regular partial triangulations (answering a question by F. Santos in the unexpected direction).","lang":"eng"}],"intvolume":"       164","date_created":"2020-06-22T09:14:19Z","quality_controlled":"1","publication":"36th International Symposium on Computational Geometry","volume":164,"title":"Connectivity of triangulation flip graphs in the plane (Part II: Bistellar flips)","_id":"7990","day":"01","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","arxiv":1,"ddc":["510"]},{"date_updated":"2025-07-10T11:54:56Z","department":[{"_id":"UlWa"}],"article_processing_charge":"No","author":[{"last_name":"Avvakumov","full_name":"Avvakumov, Sergey","id":"3827DAC8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7840-5062","first_name":"Sergey"},{"first_name":"Gabriel","full_name":"Nivasch, Gabriel","last_name":"Nivasch"}],"doi":"10.4230/LIPIcs.SoCG.2020.12","publication_status":"published","oa_version":"Published Version","type":"conference","status":"public","external_id":{"arxiv":["1909.00263"]},"file":[{"file_id":"8007","date_created":"2020-06-23T11:13:49Z","access_level":"open_access","creator":"dernst","content_type":"application/pdf","date_updated":"2020-07-14T12:48:06Z","file_name":"2020_LIPIcsSoCG_Avvakumov.pdf","checksum":"6872df6549142f709fb6354a1b2f2c06","relation":"main_file","file_size":575896}],"publication_identifier":{"issn":["1868-8969"],"isbn":["9783959771436"]},"conference":{"end_date":"2020-06-26","name":"SoCG: Symposium on Computational Geometry","start_date":"2020-06-22","location":"Zürich, Switzerland"},"month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","scopus_import":"1","project":[{"grant_number":"P31312","name":"Algorithms for Embeddings and Homotopy Theory","_id":"26611F5C-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"file_date_updated":"2020-07-14T12:48:06Z","license":"https://creativecommons.org/licenses/by/3.0/","has_accepted_license":"1","article_number":"12:1 - 12:15","citation":{"ama":"Avvakumov S, Nivasch G.

Our process, which we call homotopic curve shortening (HCS), starts with a closed curve (which might self-intersect) in the presence of a set P⊂ ℝ² of point obstacles, and evolves in discrete steps, where each step consists of (1) taking shortcuts around the obstacles, and (2) reducing the curve to its shortest homotopic equivalent. We find experimentally that, if the initial curve is held fixed and P is chosen to be either a very fine regular grid or a uniformly random point set, then HCS behaves at the limit like the affine curve-shortening flow (ACSF). This connection between HCS and ACSF generalizes the link between \"grid peeling\" and the ACSF observed by Eppstein et al. (2017), which applied only to convex curves, and which was studied only for regular grids. We prove that HCS satisfies some properties analogous to those of ACSF: HCS is invariant under affine transformations, preserves convexity, and does not increase the total absolute curvature. Furthermore, the number of self-intersections of a curve, or intersections between two curves (appropriately defined), does not increase. Finally, if the initial curve is simple, then the number of inflection points (appropriately defined) does not increase.","lang":"eng"}],"date_created":"2020-06-22T09:14:19Z","intvolume":"       164","quality_controlled":"1","publication":"36th International Symposium on Computational Geometry","volume":164,"title":"Homotopic curve shortening and the affine curve-shortening flow","_id":"7991","day":"01","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","arxiv":1,"ddc":["510"]},{"oa_version":"Published Version","type":"conference","doi":"10.4230/LIPIcs.SoCG.2020.62","publication_status":"published","status":"public","department":[{"_id":"UlWa"}],"date_updated":"2025-07-10T11:54:57Z","author":[{"last_name":"Patakova","full_name":"Patakova, Zuzana","id":"48B57058-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3975-1683","first_name":"Zuzana"},{"last_name":"Tancer","full_name":"Tancer, Martin","first_name":"Martin","orcid":"0000-0002-1191-6714","id":"38AC689C-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Uli","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1494-0568","full_name":"Wagner, Uli","last_name":"Wagner"}],"article_processing_charge":"No","file_date_updated":"2020-07-14T12:48:06Z","corr_author":"1","scopus_import":"1","language":[{"iso":"eng"}],"article_number":"62:1 - 62:16","has_accepted_license":"1","citation":{"mla":"Patakova, Zuzana, et al. “Barycentric Cuts through a Convex Body.” <i>36th International Symposium on Computational Geometry</i>, vol. 164, 62:1-62:16, Schloss Dagstuhl - Leibniz-Zentrum für Informatik, 2020, doi:<a href=\"https://doi.org/10.4230/LIPIcs.SoCG.2020.62\">10.4230/LIPIcs.SoCG.2020.62</a>.","ieee":"Z.

In 1961, Grünbaum raised the question whether, for every K, there exists an interior point p through which there are at least n+1 distinct barycentric hyperplanes. Two years later, this was seemingly resolved affirmatively by showing that this is the case if p=p₀ is the point of maximal depth in K. However, while working on a related question, we noticed that one of the auxiliary claims in the proof is incorrect. Here, we provide a counterexample; this re-opens Grünbaum’s question. It follows from known results that for n ≥ 2, there are always at least three distinct barycentric cuts through the point p₀ ∈ K of maximal depth.

One example where multiple barrier effects are coupled consists of a single trait that is under divergent natural selection and also mediates assortative mating. Such multiple‐effect traits can strongly reduce gene flow. However, there are few cases where patterns of assortative mating have been described quantitatively and their impact on gene flow has been determined. Two ecotypes of the coastal marine snail, Littorina saxatilis , occur in North Atlantic rocky‐shore habitats dominated by either crab predation or wave action. There is evidence for divergent natural selection acting on size, and size‐assortative mating has previously been documented. Here, we analyze the mating pattern in L. saxatilis with respect to size in intensively sampled transects across boundaries between the habitats. We show that the mating pattern is mostly conserved between ecotypes and that it generates both assortment and directional sexual selection for small male size. Using simulations, we show that the mating pattern can contribute to reproductive isolation between ecotypes but the barrier to gene flow is likely strengthened more by sexual selection than by assortment.","lang":"eng"}],"issue":"7","year":"2020","date_published":"2020-07-01T00:00:00Z","oa":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"project":[{"grant_number":"797747","call_identifier":"H2020","_id":"265B41B8-B435-11E9-9278-68D0E5697425","name":"Theoretical and empirical approaches to understanding Parallel Adaptation"}],"file_date_updated":"2020-11-25T10:49:48Z","scopus_import":"1","language":[{"iso":"eng"}],"has_accepted_license":"1","citation":{"ama":"Perini S, Rafajlović M, Westram AM, Johannesson K, Butlin RK.

Although PTP has a uniquely large magnitude at hippocampal mossy fiber-CA3 pyramidal neuron synapses, it is unclear whether it can be induced by natural activity and whether its lifetime is sufficient to support short-term memory. We combined in vivo recordings from granule cells (GCs), in vitro paired recordings from mossy fiber terminals and postsynaptic CA3 neurons, and “flash and freeze” electron microscopy. PTP was induced at single synapses and showed a low induction threshold adapted to sparse GC activity in vivo. PTP was mainly generated by enlargement of the readily releasable pool of synaptic vesicles, allowing multiplicative interaction with other plasticity forms. PTP was associated with an increase in the docked vesicle pool, suggesting formation of structural “pool engrams.” Absence of presynaptic activity extended the lifetime of the potentiation, enabling prolonged information storage in the hippocampal network."}],"date_created":"2020-06-22T13:29:05Z","issue":"3","year":"2020","date_published":"2020-08-05T00:00:00Z","oa":1,"tmp":{"short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png"}},{"month":"06","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"issn":["2643-1564"]},"file":[{"file_name":"2020_PhysicalReviewResearch_Michailidis.pdf","date_updated":"2020-07-14T12:48:08Z","relation":"main_file","checksum":"e6959dc8220f14a008d1933858795e6d","file_size":2066011,"file_id":"8050","access_level":"open_access","date_created":"2020-06-29T14:41:27Z","content_type":"application/pdf","creator":"dernst"}],"language":[{"iso":"eng"}],"article_number":"022065","has_accepted_license":"1","citation":{"apa":"Michailidis, A., Turner, C.

While thermalization in one-dimensional systems can often be suppressed by integrability mechanisms, in two spatial dimensions thermalization is expected to be far more effective due to the increased phase space. In this work we propose a general framework for escaping or delaying the emergence of the thermal state in two-dimensional arrays of Rydberg atoms via the mechanism of quantum scars, i.e., initial states that fail to thermalize. The suppression of thermalization is achieved in two complementary ways: by adding local perturbations or by adjusting the driving Rabi frequency according to the local connectivity of the lattice. We demonstrate that these mechanisms allow us to realize robust quantum scars in various two-dimensional lattices, including decorated lattices with nonconstant connectivity. In particular, we show that a small decrease of the Rabi frequency at the corners of the lattice is crucial for mitigating the strong boundary effects in two-dimensional systems. Our results identify synchronization as an important tool for future experiments on two-dimensional quantum scars."}]},{"publication_status":"published","doi":"10.1038/s41467-020-16932-z","type":"journal_article","oa_version":"Published Version","isi":1,"status":"public","date_updated":"2025-04-15T08:09:37Z","article_processing_charge":"No","author":[{"last_name":"Lukacisinova","full_name":"Lukacisinova, Marta","first_name":"Marta","orcid":"0000-0002-2519-8004","id":"4342E402-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Fernando, Booshini","last_name":"Fernando","first_name":"Booshini"},{"orcid":"0000-0003-4398-476X","id":"3E6DB97A-F248-11E8-B48F-1D18A9856A87","first_name":"Mark Tobias","full_name":"Bollenbach, Mark Tobias","last_name":"Bollenbach"}],"extern":"1","scopus_import":"1","project":[{"grant_number":"P27201-B22","name":"Revealing the mechanisms underlying drug interactions","call_identifier":"FWF","_id":"25E9AF9E-B435-11E9-9278-68D0E5697425"},{"grant_number":"RGP0042/2013","_id":"25EB3A80-B435-11E9-9278-68D0E5697425","name":"Revealing the fundamental limits of cell growth"}],"file_date_updated":"2020-07-14T12:48:08Z","citation":{"ama":"Lukacisinova M, Fernando B, Bollenbach MT.

Here, we show that strong epistasis between resistance mutations and systematically identified genes can be exploited to control spontaneous resistance evolution. We evolved hundreds of Escherichia coli K-12 mutant populations in parallel, using a robotic platform that tightly controls population size and selection pressure. We find a global diminishing-returns epistasis pattern: strains that are initially more sensitive generally undergo larger resistance gains. However, some gene deletion strains deviate from this general trend and curtail the evolvability of resistance, including deletions of genes for membrane transport, LPS biosynthesis, and chaperones. Deletions of efflux pump genes force evolution on inferior mutational paths, not explored in the wild type, and some of these essentially block resistance evolution. This effect is due to strong negative epistasis with resistance mutations. The identified genes and cellular functions provide potential targets for development of adjuvants that may block spontaneous resistance evolution when combined with antibiotics."}],"date_created":"2020-06-29T07:59:35Z","quality_controlled":"1","date_published":"2020-06-19T00:00:00Z","year":"2020","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"oa":1,"_id":"8037","publisher":"Springer Nature","day":"19","ddc":["570"],"pmid":1,"publication":"Nature Communications","volume":11,"article_type":"original","title":"Highly parallel lab evolution reveals that epistasis can curb the evolution of antibiotic resistance"},{"year":"2020","issue":"24","date_published":"2020-06-17T00:00:00Z","oa":1,"quality_controlled":"1","abstract":[{"text":"In the present work, we report a solution-based strategy to produce crystallographically textured SnSe bulk nanomaterials and printed layers with optimized thermoelectric performance in the direction normal to the substrate. Our strategy is based on the formulation of a molecular precursor that can be continuously decomposed to produce a SnSe powder or printed into predefined patterns. The precursor formulation and decomposition conditions are optimized to produce pure phase 2D SnSe nanoplates. The printed layer and the bulk material obtained after hot press displays a clear preferential orientation of the crystallographic domains, resulting in an ultralow thermal conductivity of 0.55 W m–1 K–1 in the direction normal to the substrate. Such textured nanomaterials present highly anisotropic properties with the best thermoelectric performance in plane, i.e., in the directions parallel to the substrate, which coincide with the crystallographic bc plane of SnSe. This is an unfortunate characteristic because thermoelectric devices are designed to create/harvest temperature gradients in the direction normal to the substrate. We further demonstrate that this limitation can be overcome with the introduction of small amounts of tellurium in the precursor. The presence of tellurium allows one to reduce the band gap and increase both the charge carrier concentration and the mobility, especially the cross plane, with a minimal decrease of the Seebeck coefficient.

Complex I, the first and the largest protein complex of the chain, harvests electrons from NADH to reduce quinone, while pumping protons across the mitochondrial membrane. Detailed knowledge of the working principle of such coupled charge-transfer processes remains, however, fragmentary due to bottlenecks in understanding redox-driven conformational transitions and their interplay with the hydrated proton pathways. Complex I from Thermus thermophilus encases 16 subunits with nine iron–sulfur clusters, reduced by electrons from NADH. Here, employing the latest crystal structure of T. thermophilus complex I, we have used microsecond-scale molecular dynamics simulations to study the chemo-mechanical coupling between redox changes of the iron–sulfur clusters and conformational transitions across complex I. First, we identify the redox switches within complex I, which allosterically couple the dynamics of the quinone binding pocket to the site of NADH reduction. Second, our free-energy calculations reveal that the affinity of the quinone, specifically menaquinone, for the binding-site is higher than that of its reduced, menaquinol form—a design essential for menaquinol release. Remarkably, the barriers to diffusive menaquinone dynamics are lesser than that of the more ubiquitous ubiquinone, and the naphthoquinone headgroup of the former furnishes stronger binding interactions with the pocket, favoring menaquinone for charge transport in T. thermophilus. Our computations are consistent with experimentally validated mutations and hierarchize the key residues into three functional classes, identifying new mutation targets. Third, long-range hydrogen-bond networks connecting the quinone-binding site to the transmembrane subunits are found to be responsible for proton pumping. Put together, the simulations reveal the molecular design principles linking redox reactions to quinone turnover to proton translocation in complex I.","lang":"eng"}],"date_created":"2020-06-29T07:59:35Z","intvolume":"       142","year":"2020","issue":"20","date_published":"2020-05-20T00:00:00Z","publisher":"American Chemical Society","day":"20","_id":"8040","pmid":1,"publication":"Journal of the American Chemical Society","article_type":"original","title":"Charge transfer and chemo-mechanical coupling in respiratory complex I","volume":142,"type":"journal_article","oa_version":"None","publication_status":"published","doi":"10.1021/jacs.9b13450","status":"public","isi":1,"department":[{"_id":"LeSa"}],"date_updated":"2025-07-10T11:55:02Z","article_processing_charge":"No","author":[{"first_name":"Chitrak","full_name":"Gupta, Chitrak","last_name":"Gupta"},{"full_name":"Khaniya, Umesh","last_name":"Khaniya","first_name":"Umesh"},{"first_name":"Chun Kit","last_name":"Chan","full_name":"Chan, Chun Kit"},{"first_name":"Francois","last_name":"Dehez","full_name":"Dehez, Francois"},{"first_name":"Mrinal","last_name":"Shekhar","full_name":"Shekhar, Mrinal"},{"full_name":"Gunner, M.

However, especially with an electrode approaching the cathodic (reductive) stability, cycling stability is insufficient. While stability critically relies on a solid electrolyte interphase (SEI), the mechanism behind the cathodic stability limit remains unclear. Here, we reveal two distinct reduction potentials for the chemical environments of ‘free’ and ‘bound’ water and that both contribute to SEI formation. Free-water is reduced ~1V above bound water in a hydrogen evolution reaction (HER) and responsible for SEI formation via reactive intermediates of the HER; concurrent LiTFSI precipitation/dissolution establishes a dynamic interface. The free-water population emerges, therefore, as the handle to extend the cathodic limit of aqueous electrolytes and the battery cycling stability.","lang":"eng"}],"date_created":"2020-06-29T16:15:49Z","intvolume":"       132","quality_controlled":"1"},{"doi":"10.48550/arXiv.2004.00642","main_file_link":[{"url":"https://arxiv.org/abs/2004.00642","open_access":"1"}],"publication_status":"submitted","date_created":"2020-06-29T23:55:23Z","abstract":[{"lang":"eng","text":"We present a generative model of images that explicitly reasons over the set\r\nof objects they show.
