While sharing the same aspirational goal, these approaches have never been tested under the same\r\nexperimental conditions on real data. In this paper, we take a unified view of previous work, highlighting message discrepancies that we address empirically, and providing recommendations on how to measure the robustness of a model and how to improve it. To this end, we collect 172 publicly available dataset pairs for training and out-of-distribution evaluation of accuracy, calibration error, adversarial attacks, environment invariance, and synthetic corruptions. We fine-tune over 31k networks, from nine different architectures in the many- and\r\nfew-shot setting. Our findings confirm that in- and out-of-distribution accuracies tend to increase jointly, but show that their relation is largely dataset-dependent, and in general more nuanced and more complex than posited by previous, smaller scale studies.","lang":"eng"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-09-06T10:34:43Z","arxiv":1,"main_file_link":[{"url":"https://arxiv.org/abs/2207.09239","open_access":"1"}],"publication":"36th Conference on Neural Information Processing Systems","title":"Assaying out-of-distribution generalization in transfer learning","date_created":"2023-08-22T14:01:13Z","alternative_title":["Advances in Neural Information Processing Systems"],"citation":{"ista":"Wenzel F, Dittadi A, Gehler PV, Carl-Johann Simon-Gabriel C-JS-G, Horn M, Zietlow D, Kernert D, Russell C, Brox T, Schiele B, Schölkopf B, Locatello F. 2022.

One particularly promising approach is to begin with low-dimensional, pretrained representations of our world, which should facilitate efficient downstream learning and generalization. By training 240 representations and over 10,000 reinforcement learning (RL) policies on a simulated robotic setup, we evaluate to what extent different properties of\r\npretrained VAE-based representations affect the OOD generalization of downstream agents. We observe that many agents are surprisingly robust to realistic distribution shifts, including the challenging sim-to-real case. In addition, we find that the generalization performance of a simple downstream proxy task reliably predicts the generalization performance of our RL agents\r\nunder a wide range of OOD settings.

Recent deep learning approaches for trajectory prediction show promising performance and partially attribute this to successful reasoning about agent-agent interactions. However, it remains unclear which features such black-box models actually learn to use for making predictions. This paper proposes a procedure that quantifies the contributions\r\nof different cues to model performance based on a variant of Shapley values. Applying this procedure to state-of-the-art trajectory prediction methods on standard benchmark datasets shows that they are, in fact, unable to reason about interactions. Instead, the past trajectory of the target is the only feature used for predicting its future. For a task with richer social\r\ninteraction patterns, on the other hand, the tested models do pick up such interactions to a certain extent, as quantified by our feature attribution method. We discuss the limits of the proposed method and its links to causality.","lang":"eng"}],"department":[{"_id":"FrLo"}],"article_processing_charge":"No"},{"citation":{"mla":"Rahaman, Nasim, et al. “A General Purpose Neural Architecture for Geospatial Systems.” 36th Conference on Neural Information Processing Systems.","ista":"Rahaman N, Weiss M, Träuble F, Locatello F, Lacoste A, Bengio Y, Pal C, Li LE, Schölkopf B.

The designs are stable, folded, and soluble in isolation and rapidly assemble upon mixing, and crystal structures are close to the computational models. We construct linearly arranged hetero-oligomers with up to six different components, branched hetero-oligomers, closed C4-symmetric two-component rings, and hetero-oligomers assembled on a cyclic homo-oligomeric central hub and demonstrate that such complexes can readily reconfigure through subunit exchange.

In this study, we identified a recurrent homozygous variant in MED11 (c.325C>T; p.Arg109Ter) in 7 affected individuals from 5 unrelated families. Methods: To investigate the genetic cause of the disease, exome or genome sequencing were performed in 5 unrelated families identified via different research networks and Matchmaker Exchange. Deep clinical and brain imaging evaluations were performed by clinical pediatric neurologists and neuroradiologists. The functional effect of the candidate variant on both MED11 RNA and protein was assessed using reverse transcriptase polymerase chain reaction and western blotting using fibroblast cell lines derived from 1 affected individual and controls and through computational approaches. Knockouts in zebrafish were generated using clustered regularly interspaced short palindromic repeats/Cas9. Results: The disease was characterized by microcephaly, profound neurodevelopmental impairment, exaggerated startle response, myoclonic seizures, progressive widespread neurodegeneration, and premature death. Functional studies on patient-derived fibroblasts did not show a loss of protein function but rather disruption of the C-terminal of MED11, likely impairing binding to other MED subunits. A zebrafish knockout model recapitulates key clinical phenotypes. Conclusion: Loss of the C-terminal of MED subunit 11 may affect its binding efficiency to other MED subunits, thus implicating the MED-complex stability in brain development and neurodegeneration.

Presently, only one family with biallelic WARS1 variants has been described. We present three affected individuals from two families with biallelic variants (p.Met1? and p.(Asp419Asn)) in WARS1, showing varying severities of developmental delay and intellectual disability. Hearing impairment and microcephaly, as well as abnormalities of the brain, skeletal system, movement/gait, and behavior were variable features. Phenotyping of knocked down wars-1 in a Caenorhabditis elegans model showed depletion is associated with defects in germ cell development. A wars1 knockout vertebrate model recapitulates the human clinical phenotypes, confirms variant pathogenicity, and uncovers evidence implicating the p.Met1? variant as potentially impacting an exon critical for normal hearing. Together, our findings provide consolidating evidence for biallelic disruption of WARS1 as causal for an autosomal recessive neurodevelopmental syndrome and present a vertebrate model that recapitulates key phenotypes observed in patients.","lang":"eng"}],"publisher":"Wiley","date_created":"2023-09-20T20:58:24Z","title":"Biallelic variants in WARS1 cause a highly variable neurodevelopmental syndrome and implicate a critical exon for normal auditory function","publication":"Human Mutation","keyword":["autosomal recessive","biallelic variants","C","elegans","translation initiation sites","tryptophanyl-tRNA synthetase 1 (WARS1)","WHEP domain","zebrafish"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-09-25T08:54:14Z"},{"oa_version":"Published Version","type":"journal_article","month":"10","scopus_import":"1","ddc":["570"],"page":"1454-1471","article_processing_charge":"No","article_type":"original","publication_identifier":{"issn":["1059-7794"]},"day":"01","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"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"},"doi":"10.1002/humu.24430","_id":"14357","volume":43,"date_created":"2023-09-20T20:59:33Z","title":"WARS1 and SARS1: Two tRNA synthetases implicated in autosomal recessive microcephaly","publication":"Human Mutation","keyword":["aminoacylation","aminoacyl-tRNA synthetase","ARS","CRISPR","Cas9","intellectual disability","microcephaly","SARS1","tRNA","WARS1","zebrafish"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","pmid":1,"date_updated":"2023-09-25T08:43:06Z","oa":1,"file":[{"creator":"dernst","file_name":"2022_HumanMutation_Boegershausen.pdf","file_size":4863605,"relation":"main_file","content_type":"application/pdf","checksum":"c31fc91e0445c35b9da83eb911a9b552","date_updated":"2023-09-25T08:41:23Z","access_level":"open_access","file_id":"14367","date_created":"2023-09-25T08:41:23Z","success":1}],"abstract":[{"lang":"eng","text":"Aminoacylation of transfer RNA (tRNA) is a key step in protein biosynthesis, carried out by highly specific aminoacyl-tRNA synthetases (ARSs).

Seryl-tRNA synthetase 1 (SARS1) has rarely been implicated in an autosomal recessive developmental disorder. Here, we report five individuals with biallelic missense variants in WARS1 or SARS1, who presented with an overlapping phenotype of microcephaly, developmental delay, intellectual disability, and brain anomalies. Structural mapping showed that the SARS1 variant is located directly within the enzyme’s active site, most likely diminishing activity, while the WARS1 variant is located in the N-terminal domain. We further characterize the identified WARS1 variant by showing that it negatively impacts protein abundance and is unable to rescue the phenotype of a CRISPR/Cas9 wars1 knockout zebrafish model. In summary, we describe two overlapping autosomal recessive syndromes caused by variants in WARS1 and SARS1, present functional insights into the pathogenesis of the WARS1-related syndrome and define an emerging disease spectrum: ARS-related developmental disorders with or without microcephaly."}],"publisher":"Wiley","has_accepted_license":"1","intvolume":" 43","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","issue":"10","author":[{"last_name":"Boegershausen","first_name":"Nina","full_name":"Boegershausen, Nina"},{"last_name":"Krawczyk","full_name":"Krawczyk, Hannah E.","first_name":"Hannah E."},{"full_name":"Jamra, Rami A.","first_name":"Rami A.","last_name":"Jamra"},{"full_name":"Lin, Sheng-Jia","first_name":"Sheng-Jia","last_name":"Lin"},{"last_name":"Yigit","first_name":"Goekhan","full_name":"Yigit, Goekhan"},{"last_name":"Huening","full_name":"Huening, Irina","first_name":"Irina"},{"full_name":"Polo, Anna M.","first_name":"Anna M.","last_name":"Polo"},{"last_name":"Vona","full_name":"Vona, Barbara","first_name":"Barbara"},{"id":"3b3d2888-1ff6-11ee-9fa6-8f209ca91fe3","full_name":"Huang, Kevin","orcid":"0000-0002-2512-7812","first_name":"Kevin","last_name":"Huang"},{"full_name":"Schmidt, Julia","first_name":"Julia","last_name":"Schmidt"},{"first_name":"Janine","full_name":"Altmueller, Janine","last_name":"Altmueller"},{"full_name":"Luppe, Johannes","first_name":"Johannes","last_name":"Luppe"},{"last_name":"Platzer","first_name":"Konrad","full_name":"Platzer, Konrad"},{"last_name":"Doergeloh","full_name":"Doergeloh, Beate B.","first_name":"Beate B."},{"last_name":"Busche","full_name":"Busche, Andreas","first_name":"Andreas"},{"last_name":"Biskup","full_name":"Biskup, Saskia","first_name":"Saskia"},{"full_name":"Mendes, I, Marisa","first_name":"Marisa","last_name":"Mendes, I"},{"first_name":"Desiree E.

In recent years, a fascinating theory of high-dimensional expanders has begun to emerge, which is still in a formative stage but has nonetheless already lead to a number of striking results. Unlike for graphs, in higher dimensions there is a rich array of non-equivalent notions of expansion (coboundary expansion, cosystolic expansion, topological expansion, spectral expansion, etc.), with differents strengths and applications. In this talk, we will survey this landscape of high-dimensional expansion, with a focus on two main results. First, we will present Gromov’s Topological Overlap Theorem, which asserts that coboundary expansion (a quantitative version of vanishing mod 2 cohomology) implies topological expansion (roughly, the property that for every map from a simplicial complex to a manifold of the same dimension, the images of a positive fraction of the simplices have a point in common). Second, we will outline a construction of bounded degree 2-dimensional topological expanders, due to Kaufman, Kazhdan, and Lubotzky."}],"intvolume":" 438","author":[{"orcid":"0000-0002-1494-0568","full_name":"Wagner, Uli","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","first_name":"Uli","last_name":"Wagner"}],"year":"2022","date_published":"2022-01-01T00:00:00Z","publication_status":"published","status":"public","corr_author":"1","citation":{"chicago":"Wagner, Uli. “High-Dimensional Expanders (after Gromov, Kaufman, Kazhdan, Lubotzky, and Others).” Bulletin de La Societe Mathematique de France.

Realizing reversed conductance decay is an important step toward making long and highly conducting molecular wires. Recent work has shown that one-dimensional topological insulators (1D TIs) can exhibit reversed conductance decay due to their nontrivial edge states. The Su–Schrieffer–Heeger (SSH) model for 1D TIs relates to the electronic structure of these isolated molecules but not their electron transport properties as single-molecule junctions. Herein, we use a tight-binding approach to demonstrate that polyacetylene and other diradicaloid 1D TIs show a reversed conductance decay at the short chain limit. We explain these conductance trends by analyzing the impact of the edge states in these 1D systems on the single-molecule junction transmission. Additionally, we discuss how the self-energy from the electrode-molecule coupling and the on-site energy of the edge sites can be tuned to create longer wires with reversed conductance decays.","lang":"eng"}],"OA_place":"repository","issue":"41","intvolume":" 13","author":[{"full_name":"Li, Liang","first_name":"Liang","last_name":"Li"},{"last_name":"Gunasekaran","full_name":"Gunasekaran, Suman","first_name":"Suman"},{"last_name":"Wei","full_name":"Wei, Yujing","first_name":"Yujing"},{"last_name":"Nuckolls","full_name":"Nuckolls, Colin","first_name":"Colin"},{"last_name":"Venkataraman","first_name":"Latha","orcid":"0000-0002-6957-6089","full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf"}],"extern":"1","publication_status":"published","status":"public","date_published":"2022-10-11T00:00:00Z","year":"2022","citation":{"mla":"Li, Liang, et al. “Reversed Conductance Decay of 1D Topological Insulators by Tight-Binding Analysis.” The Journal of Physical Chemistry Letters, vol. 13, no. 41, American Chemical Society, 2022, pp. 9703–10, doi:10.1021/acs.jpclett.2c02812.","apa":"Li, L., Gunasekaran, S., Wei, Y., Nuckolls, C., & Venkataraman, L.

A key advantage is their ability to exhibit quasi-metallic transport, in contrast to conjugated molecular wires which typically exhibit a low conductance that decays as the wire length increases. Here, we study a family of oligophenylene-bridged bis(triarylamines) with tunable and stable mono- or di-radicaloid character. These wires can undergo one- and two-electron chemical oxidations to the corresponding mono-cation and di-cation, respectively. We show that the oxidized wires exhibit reversed conductance decay with increasing length, consistent with the expectation for Su–Schrieffer–Heeger-type one-dimensional topological insulators. The 2.6-nm-long di-cation reported here displays a conductance greater than 0.1G0, where G0 is the conductance quantum, a factor of 5,400 greater than the neutral form. The observed conductance–length relationship is similar between the mono-cation and di-cation series. Density functional theory calculations elucidate how the frontier orbitals and delocalization of radicals facilitate the observed non-classical quasi-metallic behaviour.","lang":"eng"}],"publisher":"Springer Nature"},{"article_type":"letter_note","doi":"10.1021/acs.nanolett.2c01549","day":"31","publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"volume":22,"_id":"17872","month":"05","type":"journal_article","oa_version":"None","page":"4919-4924","scopus_import":"1","article_processing_charge":"No","author":[{"last_name":"Lee","first_name":"Woojung","full_name":"Lee, Woojung"},{"first_name":"Shayan","full_name":"Louie, Shayan","last_name":"Louie"},{"last_name":"Evans","first_name":"Austin M.","full_name":"Evans, Austin M."},{"last_name":"Orchanian","full_name":"Orchanian, Nicholas M.","first_name":"Nicholas M."},{"last_name":"Stone","full_name":"Stone, Ilana B.","first_name":"Ilana B."},{"last_name":"Zhang","full_name":"Zhang, Boyuan","first_name":"Boyuan"},{"last_name":"Wei","first_name":"Yujing","full_name":"Wei, Yujing"},{"first_name":"Xavier","full_name":"Roy, Xavier","last_name":"Roy"},{"last_name":"Nuckolls","first_name":"Colin","full_name":"Nuckolls, Colin"},{"last_name":"Venkataraman","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","full_name":"Venkataraman, Latha","orcid":"0000-0002-6957-6089","first_name":"Latha"}],"issue":"12","intvolume":" 22","language":[{"iso":"eng"}],"external_id":{"pmid":["35640062"]},"quality_controlled":"1","citation":{"mla":"Lee, Woojung, et al. “Increased Molecular Conductance in Oligo[n]Phenylene Wires by Thermally Enhanced Dihedral Planarization.” Nano Letters, vol. 22, no. 12, American Chemical Society, 2022, pp. 4919–24, doi:10.1021/acs.nanolett.2c01549.","ieee":"W.

Although several experimental studies have shown counter examples, robust models to describe this temperature dependence have not been thoroughly developed. Here, we demonstrate that dynamic molecular structures lead to temperature-dependent conductance within coherent tunneling regime. Using a custom-built variable-temperature scanning tunneling microscopy break-junction instrument, we find that oligo[n]phenylenes exhibit clear temperature-dependent conductance. Our calculations reveal that thermally activated dihedral rotations allow these molecular wires to have a higher probability of being in a planar conformation. As the tunneling occurs primarily through π-orbitals, enhanced coplanarization substantially increases the time-averaged tunneling probability. These calculations are consistent with the observation that more rotational pivot points in longer molecular wires leads to larger temperature-dependence on conductance. These findings reveal that molecular conductance within coherent and off-resonant electron transport regimes can be controlled by manipulating dynamic molecular structure.","lang":"eng"}],"publisher":"American Chemical Society"},{"publisher":"Wiley","oa":1,"OA_place":"repository","abstract":[{"text":"AbstractA critical overview of the theory of the chirality‐induced spin selectivity (CISS) effect, that is, phenomena in which the chirality of molecular species imparts significant spin selectivity to various electron processes, is provided.

However, weak electrical conductivities inherent to the non-conjugated molecular motifs used thus far limit device performance and the practical relevance of these materials. We herein address this problem by developing a modular approach to construct π-conjugated RA-2DPs with a new polycyclic aromatic redox-active building block PDI-DA. Efficient imine-condensation between PDI-DA and two polyfunctional amine nodes followed by quantitative alkyl chain removal produced RA-2DPs TAPPy-PDI and TAPB-PDI as conjugated, porous, polycrystalline networks. In-plane conjugation and permanent porosity endow these materials with high electrical conductivity and high ion diffusion rates. As such, both RA-2DPs function as organic cathode materials with good rate performance and excellent cycling stability. Importantly, the improved design enables higher areal mass-loadings than were previously available, which drives a practical demonstration of TAPPy-PDI as the power source for a series of LED lights. Collectively, this investigation discloses viable synthetic methodologies and design principles for the realization of high-performance organic cathode materials."}],"OA_place":"publisher","publisher":"Royal Society of Chemistry","date_created":"2024-09-06T13:08:38Z","publication":"Chemical Science","title":"π-Conjugated redox-active two-dimensional polymers as organic cathode materials","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"url":"https://doi.org/10.1039/D1SC07157B","open_access":"1"}],"date_updated":"2024-12-10T09:54:17Z"}]
