Surprisingly, despite being “overfit” in this way, they tend to generalize well to future data, thereby defying the classic bias–variance trade-off of machine learning theory. Of the many possible explanations, a prevalent one is that training by stochastic gradient descent (SGD) imposes an implicit bias that leads it to learn simple functions, and these simple functions generalize well. However, the specifics of this implicit bias are not well understood.\r\nIn this work, we explore the smoothness conjecture which states that SGD is implicitly biased towards learning functions that are smooth. We propose several measures to formalize the intuitive notion of smoothness, and we conduct experiments to determine whether SGD indeed implicitly optimizes for these measures. Our findings rule out the possibility that smoothness measures based on first-order derivatives are being implicitly enforced. They are supportive, though, of the smoothness conjecture for measures based on second-order derivatives.","lang":"eng"}],"publication_status":"published","status":"public","external_id":{"isi":["001500603200018"]},"oa_version":"Submitted Version","title":"Does SGD implicitly optimize for smoothness?","doi":"10.1007/978-3-030-71278-5_18","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","volume":12544,"oa":1,"file_date_updated":"2022-08-12T07:27:58Z","quality_controlled":"1","date_updated":"2025-09-10T10:00:33Z","date_created":"2021-03-01T09:01:16Z","publication":"42nd German Conference on Pattern Recognition","citation":{"ama":"Volhejn V, Lampert C.

To exploit the soil effectively, roots must constantly integrate environmental signals and react through adjustment of growth and development. Important components of the root management strategy involve a rapid modulation of the root growth kinetics and growth direction, as well as an increase of the root system radius through formation of lateral roots (LRs). At the molecular level, such a fascinating growth and developmental flexibility of root organ requires regulatory networks that guarantee stability of the developmental program but also allows integration of various environmental inputs. The plant hormone auxin is one of the principal endogenous regulators of root system architecture by controlling primary root growth and formation of LR. In this review, we discuss recent progress in understanding molecular networks where auxin is one of the main players shaping the root system and acting as mediator between endogenous cues and environmental factors."}],"publication_status":"published","scopus_import":"1","year":"2021","main_file_link":[{"url":"https://doi.org/10.1101/cshperspect.a039941","open_access":"1"}],"issue":"7","project":[{"name":"Hormonal regulation of plant adaptive responses to environmental signals","_id":"2685A872-B435-11E9-9278-68D0E5697425"}],"external_id":{"pmid":["33558367"],"isi":["000692069100001"]},"doi":"10.1101/cshperspect.a039941","title":"Auxin-regulated lateral root organogenesis","acknowledgement":"We apologize to all the authors whose scientific work could not be cited and discussed because of space restrictions.

This severely impacts their utility in probing the transition and the localized phase.

We focus on a modern interpretation of this concept in terms of information theory, largely centered on its application to cell specification in the early Drosophila embryo. We argue that a true physical variable (position) is encoded in local concentrations of patterning molecules, that this mapping is stochastic, and that the processes by which positions and corresponding cell fates are determined based on these concentrations need to take such stochasticity into account. With this approach, we shift the focus from biological mechanisms, molecules, genes and pathways to quantitative systems-level questions: where does positional information reside, how it is transformed and accessed during development, and what fundamental limits it is subject to?"}],"issue":"2","main_file_link":[{"url":"https://doi.org/10.1242/dev.176065","open_access":"1"}],"external_id":{"isi":["000613906000007"],"pmid":["33526425"]},"project":[{"_id":"254E9036-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Biophysics of information processing in gene regulation","grant_number":"P28844-B27"}],"doi":"10.1242/dev.176065","title":"The many bits of positional information","oa_version":"Published Version","acknowledgement":"This work was supported in part by the National Science Foundation, through the Center for the Physics of Biological Function (PHY-1734030), by the National Institutes of Health (R01GM097275) and by the Fonds zur Förderung der wissenschaftlichen Forschung (FWF P28844).

Its advantages include the abundance, low cost, and safety of its elements and a high performance at relatively elevated temperatures. However, stability issues limit its operation current and temperature, thus calling for the optimization of the material performance in the middle temperature range. Here, we present a synthetic protocol for large scale production of covellite CuS nanoparticles at ambient temperature and atmosphere, and using water as a solvent. The crystal phase and stoichiometry of the particles are afterward tuned through an annealing process at a moderate temperature under inert or reducing atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed in argon to transform to the cubic phase at ca. 400 K, while the material annealed in the presence of hydrogen undergoes two phase transitions, first to hexagonal and then to the cubic structure. The annealing atmosphere, temperature, and time allow adjustment of the density of copper vacancies and thus tuning of the charge carrier concentration and material transport properties. In this direction, the material annealed under Ar is characterized by higher electrical conductivities but lower Seebeck coefficients than the material annealed in the presence of hydrogen. By optimizing the charge carrier concentration through the annealing time, Cu2–xS with record figures of merit in the middle temperature range, up to 1.41 at 710 K, is obtained. We finally demonstrate that this strategy, based on a low-cost and scalable solution synthesis process, is also suitable for the production of high performance Cu2–xS layers using high throughput and cost-effective printing technologies."}],"publication_status":"published","scopus_import":"1","year":"2021","status":"public","corr_author":"1","publisher":"American Chemical Society ","author":[{"full_name":"Li, Mengyao","first_name":"Mengyao","last_name":"Li"},{"id":"2A70014E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7313-6740","full_name":"Liu, Yu","first_name":"Yu","last_name":"Liu"},{"last_name":"Zhang","full_name":"Zhang, Yu","first_name":"Yu"},{"first_name":"Xu","full_name":"Han, Xu","last_name":"Han"},{"last_name":"Zhang","full_name":"Zhang, Ting","first_name":"Ting"},{"first_name":"Yong","full_name":"Zuo, Yong","last_name":"Zuo"},{"last_name":"Xie","first_name":"Chenyang","full_name":"Xie, Chenyang"},{"first_name":"Ke","full_name":"Xiao, Ke","last_name":"Xiao"},{"full_name":"Arbiol, Jordi","first_name":"Jordi","last_name":"Arbiol"},{"first_name":"Jordi","full_name":"Llorca, Jordi","last_name":"Llorca"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","first_name":"Maria","last_name":"Ibáñez"},{"first_name":"Junfeng","full_name":"Liu, Junfeng","last_name":"Liu"},{"full_name":"Cabot, Andreu","first_name":"Andreu","last_name":"Cabot"}],"pmid":1,"date_published":"2021-03-01T00:00:00Z","article_processing_charge":"No","day":"01"},{"day":"03","article_processing_charge":"No","arxiv":1,"author":[{"first_name":"Guy","full_name":"Avni, Guy","orcid":"0000-0001-5588-8287","id":"463C8BC2-F248-11E8-B48F-1D18A9856A87","last_name":"Avni"},{"last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2985-7724","full_name":"Henzinger, Thomas A","first_name":"Thomas A"},{"full_name":"Žikelić, Đorđe","first_name":"Đorđe","last_name":"Žikelić"}],"publisher":"Elsevier","date_published":"2021-03-03T00:00:00Z","status":"public","abstract":[{"text":"A graph game proceeds as follows: two players move a token through a graph to produce a finite or infinite path, which determines the payoff of the game.

The well-posedness theory now applies in d-dimensions when the particle-width ϵ is proportional to  for  and N is the number of particles. This scaling is optimal in a certain Sobolev norm.

While suitable mathematical models for computing the transport are now available, obtaining the necessary material parameters needed to drive such simulations is a challenging task: direct measurements of these parameters from material samples are seldom possible. Building on the inverse scattering paradigm, we present a novel measurement approach which indirectly infers the transport parameters from extrinsic observations of multiple-scattered radiance. The novelty of the proposed approach lies in replacing structured illumination with a structured reflector bonded to the sample, and a robust fitting procedure that largely compensates for potential systematic errors in the calibration of the setup. We show the feasibility of our approach by validating simulations of complex 3D compositions of the measured materials against physical prints, using photo-polymer resins. As presented in this paper, our technique yields colorspace data suitable for accurate appearance reproduction in the area of 3D printing. Beyond that, and without fundamental changes to the basic measurement methodology, it could equally well be used to obtain spectral measurements that are useful for other application areas.","lang":"eng"}],"status":"public","date_published":"2021-03-01T00:00:00Z","publisher":"The Optical Society","author":[{"first_name":"Oskar","full_name":"Elek, Oskar","last_name":"Elek"},{"orcid":"0000-0002-3808-281X","id":"4DDBCEB0-F248-11E8-B48F-1D18A9856A87","first_name":"Ran","full_name":"Zhang, Ran","last_name":"Zhang"},{"last_name":"Sumin","full_name":"Sumin, Denis","first_name":"Denis"},{"full_name":"Myszkowski, Karol","first_name":"Karol","last_name":"Myszkowski"},{"last_name":"Bickel","full_name":"Bickel, Bernd","first_name":"Bernd","id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385"},{"last_name":"Wilkie","full_name":"Wilkie, Alexander","first_name":"Alexander"},{"first_name":"Jaroslav","full_name":"Křivánek, Jaroslav","last_name":"Křivánek"},{"first_name":"Tim","full_name":"Weyrich, Tim","last_name":"Weyrich"}],"day":"01","article_processing_charge":"No","file":[{"success":1,"checksum":"a9697ad83136c19ad87e46aa2db63cfd","access_level":"open_access","file_size":10873700,"file_id":"9269","date_created":"2021-03-22T08:15:28Z","date_updated":"2021-03-22T08:15:28Z","content_type":"application/pdf","file_name":"2021_OpticsExpress_Elek.pdf","relation":"main_file","creator":"dernst"}],"oa_version":"Published Version","acknowledgement":"H2020 Marie Skłodowska-Curie Actions (642841); European Research Council (715767); Grantová Agentura České Republiky (16-08111S, 16-18964S); Univerzita Karlova v Praze (SVV-2017-260452); Engineering and Physical Sciences Research Council (EP/K023578/1).\r\nWe are grateful to Stratasys Ltd. for access to the voxel-level print interface of the J750\r\nmachine.","doi":"10.1364/OE.406095","title":"Robust and practical measurement of volume transport parameters in solid photo-polymer materials for 3D printing","external_id":{"isi":["000624968100103"]},"project":[{"_id":"2508E324-B435-11E9-9278-68D0E5697425","name":"Distributed 3D Object Design","call_identifier":"H2020","grant_number":"642841"},{"grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425"}],"issue":"5","ec_funded":1,"file_date_updated":"2021-03-22T08:15:28Z","quality_controlled":"1","date_updated":"2025-03-31T15:58:16Z","date_created":"2021-03-14T23:01:33Z","citation":{"mla":"Elek, Oskar, et al. “Robust and Practical Measurement of Volume Transport Parameters in Solid Photo-Polymer Materials for 3D Printing.” <i>Optics Express</i>, vol. 29, no. 5, The Optical Society, 2021, pp. 7568–88, doi:<a href=\"https://doi.org/10.1364/OE.406095\">10.1364/OE.406095</a>.","apa":"Elek, O., Zhang, R., Sumin, D., Myszkowski, K., Bickel, B., Wilkie, A., … Weyrich, T.

Important antibiotics such as β-lactams and glycopeptides target peptidoglycan biosynthesis. Class A penicillin-binding proteins (PBPs) are bifunctional membrane-bound peptidoglycan synthases that polymerize glycan chains and connect adjacent stem peptides by transpeptidation. How these enzymes work in their physiological membrane environment is poorly understood. Here, we developed a novel Förster resonance energy transfer-based assay to follow in real time both reactions of class A PBPs reconstituted in liposomes or supported lipid bilayers and applied this assay with PBP1B homologues from Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii in the presence or absence of their cognate lipoprotein activator. Our assay will allow unravelling the mechanisms of peptidoglycan synthesis in a lipid-bilayer environment and can be further developed to be used for high-throughput screening for new antimicrobials.","lang":"eng"}],"scopus_import":"1","year":"2021","ec_funded":1,"project":[{"_id":"2595697A-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Self-Organization of the Bacterial Cell","grant_number":"679239"},{"name":"Synthesis of bacterial cell wall","_id":"2596EAB6-B435-11E9-9278-68D0E5697425","grant_number":"ALTF 2015-1163"},{"name":"Reconstitution of bacterial cell wall synthesis","_id":"259B655A-B435-11E9-9278-68D0E5697425","grant_number":"LT000824/2016"}],"external_id":{"isi":["000627596400001"]},"doi":"10.7554/eLife.61525","title":"Real time monitoring of peptidoglycan synthesis by membrane-reconstituted penicillin binding proteins","acknowledgement":"We thank Alexander Egan (Newcastle University) for purified proteins LpoB(sol) and LpoPPa(sol), Federico Corona (Newcastle University) for purified MepM, and Oliver Birkholz and Jacob Piehler (Department of Biology and Center of Cellular Nanoanalytics, University of Osnabru¨ ck) for their help with PBP1B reconstitution into polymer-SLBs and initial guidance on single particle tracking.

Each island belongs to one of two distinct ecological niches or habitats. Fitness is influenced by an additive trait which is under habitat‐dependent directional selection. Our analysis is based on the diffusion approximation and accounts for both genetic drift and demographic stochasticity. By neglecting linkage disequilibria, it yields the joint distribution of allele frequencies and population size on each island. We find that under hard selection, the conditions for local adaptation in a rare habitat are more restrictive for more polygenic traits: even moderate migration load per locus at very many loci is sufficient for population sizes to decline. This further reduces the efficacy of selection at individual loci due to increased drift and because smaller populations are more prone to swamping due to migration, causing a positive feedback between increasing maladaptation and declining population sizes. Our analysis also highlights the importance of demographic stochasticity, which exacerbates the decline in numbers of maladapted populations, leading to population collapse in the rare habitat at significantly lower migration than predicted by deterministic arguments."}],"publication_status":"published","year":"2021","scopus_import":"1","corr_author":"1","status":"public","ddc":["570"],"intvolume":"        75","month":"05","language":[{"iso":"eng"}],"tmp":{"image":"/images/cc_by_nc_nd.png","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","short":"CC BY-NC-ND (4.0)"},"_id":"9252","department":[{"_id":"NiBa"}],"isi":1,"page":"1030-1045","has_accepted_license":"1","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","publication_identifier":{"issn":["0014-3820"],"eissn":["1558-5646"]},"related_material":{"record":[{"relation":"research_data","id":"13062","status":"public"}]},"keyword":["Genetics","Ecology","Evolution","Behavior and Systematics","General Agricultural and Biological Sciences"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":75,"oa":1,"article_type":"original","date_created":"2021-03-20T08:22:10Z","file_date_updated":"2021-08-11T13:39:19Z","date_updated":"2025-06-12T06:35:39Z","quality_controlled":"1","publication":"Evolution","citation":{"ieee":"E.

Based on subjective impressions and anecdotal evidence, Austrian public and private life came to a sudden halt. Here we assess the effect of the lock-down quantitatively for all regions in Austria and present an analysis of daily changes of human mobility throughout Austria using near-real-time anonymized mobile phone data. We describe an efficient data aggregation pipeline and analyze the mobility by quantifying mobile-phone traffic at specific point of interests (POIs), analyzing individual trajectories and investigating the cluster structure of the origin-destination graph. We found a reduction of commuters at Viennese metro stations of over 80% and the number of devices with a radius of gyration of less than 500 m almost doubled. The results of studying crowd-movement behavior highlight considerable changes in the structure of mobility networks, revealed by a higher modularity and an increase from 12 to 20 detected communities. We demonstrate the relevance of mobility data for epidemiological studies by showing a significant correlation of the outflow from the town of Ischgl (an early COVID-19 hotspot) and the reported COVID-19 cases with an 8-day time lag. This research indicates that mobile phone usage data permits the moment-by-moment quantification of mobility behavior for a whole country. We emphasize the need to improve the availability of such data in anonymized form to empower rapid response to combat COVID-19 and future pandemics.","lang":"eng"}],"status":"public"},{"month":"03","ddc":["530"],"intvolume":"         7","article_number":"50","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)"},"language":[{"iso":"eng"}],"has_accepted_license":"1","isi":1,"_id":"9255","department":[{"_id":"FyKo"}],"publication_identifier":{"eissn":["2056-6387"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","article_type":"original","volume":7,"oa":1,"file_date_updated":"2021-03-22T11:09:34Z","date_updated":"2023-08-07T14:17:26Z","quality_controlled":"1","date_created":"2021-03-21T23:01:19Z","citation":{"apa":"Pivoluska, M., Plesch, M., Farkas, M., Ruzickova, N., Flegel, C., Valencia, N.

Existing solutions both come with drawbacks—device-independent quantum random number generators (QRNGs) are highly impractical and standard semi-device-independent QRNGs are limited to a specific physical implementation and level of trust. Here we propose a framework for semi-device-independent randomness certification, using a source of trusted vacuum in the form of a signal shutter. It employs a flexible set of assumptions and levels of trust, allowing it to be applied in a wide range of physical scenarios involving both quantum and classical entropy sources. We experimentally demonstrate our protocol with a photonic setup and generate secure random bits under three different assumptions with varying degrees of security and resulting data rates.","lang":"eng"}],"publication_status":"published","status":"public"}]
