Observations of massive stars in open clusters younger than ∼8 Myr have shown that a majority of them are in binary systems, most of which will interact during their life. While these can be used as a proxy of the initial multiplicity properties, studying populations of massive stars older than ∼20 Myr allows us to probe the outcome of these interactions after a significant number of systems have experienced mass and angular momentum transfer and may even have merged.\r\n\r\nAims. Using multi-epoch integral-field spectroscopy, we aim to investigate the multiplicity properties of the massive-star population in the dense core of the ∼40 Myr old cluster NGC 330 in the Small Magellanic Cloud in order to search for possible imprints of stellar evolution on the multiplicity properties.\r\n\r\nMethods. We obtained six epochs of VLT/MUSE observations operated in wide-field mode with the extended wavelength setup and supported by adaptive optics. We extracted spectra and measured radial velocities for stars brighter than mF814W = 19. We identified single-lined spectroscopic binaries through significant RV variability with a peak-to-peak amplitude larger than 20 km s−1. We also identified double-lined spectroscopic binaries, and quantified the observational biases for binary detection. In particular, we took into account that binary systems with similar line strengths are difficult to detect in our data set.\r\n\r\nResults. The observed spectroscopic binary fraction among stars brighter than mF814W = 19 (approximately 5.5 M⊙ on the main sequence) is fSBobs = 13.2 ± 2.0%. Considering period and mass ratio ranges from log(P) = 0.15−3.5 (about 1.4 to 3160 d), q = 0.1−1.0, and a representative set of orbital parameter distributions, we find a bias-corrected close binary fraction of fcl = 34−7+8%. This fraction seems to decline for the fainter stars, which indicates either that the close binary fraction drops in the B-type domain, or that the period distribution becomes more heavily weighted toward longer orbital periods. We further find that both fractions vary strongly in different regions of the color-magnitude diagram, which corresponds to different evolutionary stages. This probably reveals the imprint of the binary history of different groups of stars. In particular, we find that the observed spectroscopic binary fraction of Be stars (fSBobs = 2 ± 2%) is significantly lower than that of B-type stars (fSBobs = 9 ± 2%).\r\n\r\nConclusions. We provide the first homogeneous radial velocity study of a large sample of B-type stars at a low metallicity ([Fe/H] ≲ −1.0). The overall bias-corrected close binary fraction (log(P) < 3.5 d) of the B-star population in NGC 330 is lower than the fraction reported for younger Galactic and Large Magellanic Cloud clusters in previous works. More data are needed, however, to establish whether the observed differences are caused by an age or a metallicity effect.","lang":"eng"}]},{"publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"month":"12","language":[{"iso":"eng"}],"doi":"10.1051/0004-6361/202140506","quality_controlled":"1","external_id":{"arxiv":["2102.05036"]},"oa":1,"main_file_link":[{"url":"https://doi.org/10.1051/0004-6361/202140506","open_access":"1"}],"article_number":"A58","volume":656,"date_created":"2023-08-03T10:11:09Z","date_updated":"2023-08-21T11:49:15Z","author":[{"full_name":"Laplace, E.","last_name":"Laplace","first_name":"E."},{"full_name":"Justham, S.","last_name":"Justham","first_name":"S."},{"full_name":"Renzo, M.","first_name":"M.","last_name":"Renzo"},{"full_name":"Götberg, Ylva Louise Linsdotter","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","orcid":"0000-0002-6960-6911","first_name":"Ylva Louise Linsdotter","last_name":"Götberg"},{"full_name":"Farmer, R.","last_name":"Farmer","first_name":"R."},{"last_name":"Vartanyan","first_name":"D.","full_name":"Vartanyan, D."},{"full_name":"de Mink, S.

Donor stars in binary systems can lose most of their hydrogen-rich envelopes through mass transfer. As a result, not only are the surface properties affected, but so is the core structure. However, most calculations of the core-collapse properties of massive stars rely on single-star models. We present a systematic study of the difference between the pre-supernova structures of single stars and stars of the same initial mass (11–21 M⊙) that have been stripped due to stable post-main-sequence mass transfer at solar metallicity. We present the pre-supernova core composition with novel diagrams that give an intuitive representation of the isotope distribution. As shown in previous studies, at the edge of the carbon-oxygen core, the binary-stripped star models contain an extended gradient of carbon, oxygen, and neon. This layer remains until core collapse and is more extended in mass for higher initial stellar masses. It originates from the receding of the convective helium core during core helium burning in binary-stripped stars, which does not occur in single-star models. We find that this same evolutionary phase leads to systematic differences in the final density and nuclear energy generation profiles. Binary-stripped star models have systematically higher total masses of carbon at the moment of core collapse compared to single-star models, which likely results in systematically different supernova yields. In about half of our models, the silicon-burning and oxygen-rich layers merge after core silicon burning. We discuss the implications of our findings for the “explodability”, supernova observations, and nucleosynthesis of these stars. Our models are publicly available and can be readily used as input for detailed supernova simulations.","lang":"eng"}],"type":"journal_article","oa_version":"Published Version","intvolume":" 656","title":"Different to the core: The pre-supernova structures of massive single and binary-stripped stars","status":"public","_id":"13455","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"date_published":"2021-12-03T00:00:00Z","citation":{"short":"T.L.S.

Revisiting a set of binary evolution calculations using the stellar evolution code MESA, we refine our previous predictions about which systems can lead to a thermonuclear supernova and then characterize the properties of the helium star donor at the time of explosion. We convert these model properties to near-UV/optical magnitudes assuming a blackbody spectrum and support this approach using a matched stellar atmosphere model. These models will be valuable to compare with pre-explosion imaging for future supernovae, though we emphasize the observational difficulty of detecting extremely blue companions. The pre-explosion source detected in association with SN 2012Z has been interpreted as a helium star binary containing an initially ultra-massive WD in a multiday orbit. However, extending our binary models to initial CO WD masses of up to 1.2 M⊙, we find that these systems undergo off-center carbon ignitions and thus are not expected to produce thermonuclear supernovae. This tension suggests that, if SN 2012Z is associated with a helium star–WD binary, then the pre-explosion optical light from the system must be significantly modified by the binary environment and/or the WD does not have a carbon-rich interior composition.","lang":"eng"}],"type":"journal_article","doi":"10.3847/1538-4357/ac27ae","language":[{"iso":"eng"}],"external_id":{"arxiv":["2109.14817"]},"main_file_link":[{"url":"https://arxiv.org/abs/2109.14817","open_access":"1"}],"oa":1,"quality_controlled":"1","publication_identifier":{"issn":["0004-637X"],"eissn":["1538-4357"]},"month":"12","author":[{"first_name":"Tin Long Sunny","last_name":"Wong","full_name":"Wong, Tin Long Sunny"},{"last_name":"Schwab","first_name":"Josiah","full_name":"Schwab, Josiah"},{"full_name":"Götberg, Ylva Louise Linsdotter","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","orcid":"0000-0002-6960-6911","first_name":"Ylva Louise Linsdotter","last_name":"Götberg"}],"volume":922,"date_updated":"2023-08-21T11:52:05Z","date_created":"2023-08-03T10:10:58Z","year":"2021","publisher":"American Astronomical Society","publication_status":"published","extern":"1","article_number":"241"},{"external_id":{"arxiv":["2107.10933"]},"main_file_link":[{"url":"https://arxiv.org/abs/2107.10933","open_access":"1"}],"oa":1,"quality_controlled":"1","doi":"10.3847/1538-4357/ac29c5","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"month":"12","year":"2021","publisher":"American Astronomical Society","publication_status":"published","author":[{"full_name":"Renzo, M.","first_name":"M.","last_name":"Renzo"},{"orcid":"0000-0002-6960-6911","id":"d0648d0c-0f64-11ee-a2e0-dd0faa2e4f7d","last_name":"Götberg","first_name":"Ylva Louise Linsdotter","full_name":"Götberg, Ylva Louise Linsdotter"}],"volume":923,"date_created":"2023-08-03T10:10:48Z","date_updated":"2023-08-21T11:59:34Z","article_number":"277","extern":"1","citation":{"ista":"Renzo M, Götberg YLL. 2021.

We focus on the impact of mass accretion on the surface composition, internal rotation, and structure of the accretor. To anchor our models, we show that our accretor broadly reproduces the properties of ζ Ophiuchi, which has long been proposed to have accreted mass before being ejected as a runaway star when the companion exploded. We compare our accretor to models of single rotating stars and find that the later and stronger spin-up provided by mass accretion produces significant differences. Specifically, the core of the accretor retains higher spin at the end of the main sequence, and a convective layer develops that changes its density profile. Moreover, the surface of the accretor star is polluted by CNO-processed material donated by the companion. Our models show effects of mass accretion in binaries that are not captured in single rotating stellar models.

The implications are in ultrafast probing of topological phase transitions, light-field driven dissipationless electronics, and quantum computation.","lang":"eng"}],"issue":"21","type":"journal_article","oa_version":"Published Version","title":"All-optical probe of three-dimensional topological insulators based on high-harmonic generation by circularly polarized laser fields","status":"public","intvolume":" 21","_id":"13996","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2008.01265"}],"oa":1,"external_id":{"arxiv":["2008.01265"]},"quality_controlled":"1","doi":"10.1103/physreva.103.023101","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2469-9934"],"issn":["2469-9926"]},"month":"02","year":"2021","publisher":"American Physical Society","publication_status":"published","author":[{"first_name":"Denitsa Rangelova","last_name":"Baykusheva","id":"71b4d059-2a03-11ee-914d-dfa3beed6530","full_name":"Baykusheva, Denitsa Rangelova"},{"full_name":"Chacón, Alexis","first_name":"Alexis","last_name":"Chacón"},{"first_name":"Dasol","last_name":"Kim","full_name":"Kim, Dasol"},{"first_name":"Dong Eon","last_name":"Kim","full_name":"Kim, Dong Eon"},{"full_name":"Reis, David A.","last_name":"Reis","first_name":"David A."},{"last_name":"Ghimire","first_name":"Shambhu","full_name":"Ghimire, Shambhu"}],"volume":103,"date_created":"2023-08-09T13:09:26Z","date_updated":"2023-08-22T07:33:43Z","article_number":"023101","extern":"1","citation":{"ista":"Baykusheva DR, Chacón A, Kim D, Kim DE, Reis DA, Ghimire S. 2021.

In particular, we focus on the process of nonperturbative high-order harmonic generation from the paradigmatic three-dimensional topological insulator bismuth selenide (Bi2Se3) subjected to intense midinfrared laser fields. We analyze the contributions from the spin-orbit-coupled bulk states and the topological surface bands separately and reveal a major difference in how their harmonic yields depend on the ellipticity of the laser field. Bulk harmonics show a monotonic decrease in their yield as the ellipticity increases, in a manner reminiscent of high harmonic generation in gaseous media. However, the surface contribution exhibits a highly nontrivial dependence, culminating with a maximum for circularly polarized fields. We attribute the observed anomalous behavior to (i) the enhanced amplitude and the circular pattern of the interband dipole and the Berry connections in the vicinity of the Dirac point and (ii) the influence of the higher-order, hexagonal warping terms in the Hamiltonian, which are responsible for the hexagonal deformation of the energy surface at higher momenta. The latter are associated directly with spin-orbit-coupling parameters. Our results thus establish the sensitivity of strong-field-driven high harmonic emission to the topology of the band structure as well as to the manifestations of spin-orbit interaction."}]},{"publication_identifier":{"eissn":["2375-2548"]},"month":"12","doi":"10.1126/sciadv.abj8121","language":[{"iso":"eng"}],"oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1126/sciadv.abj8121"}],"external_id":{"pmid":["34860540"]},"quality_controlled":"1","extern":"1","article_number":"abj8121","author":[{"full_name":"Heck, Saijoscha","first_name":"Saijoscha","last_name":"Heck"},{"full_name":"Baykusheva, Denitsa Rangelova","last_name":"Baykusheva","first_name":"Denitsa Rangelova","id":"71b4d059-2a03-11ee-914d-dfa3beed6530"},{"full_name":"Han, Meng","first_name":"Meng","last_name":"Han"},{"first_name":"Jia-Bao","last_name":"Ji","full_name":"Ji, Jia-Bao"},{"last_name":"Perry","first_name":"Conaill","full_name":"Perry, Conaill"},{"first_name":"Xiaochun","last_name":"Gong","full_name":"Gong, Xiaochun"},{"last_name":"Wörner","first_name":"Hans Jakob","full_name":"Wörner, Hans Jakob"}],"volume":7,"date_created":"2023-08-09T13:09:02Z","date_updated":"2023-08-22T07:30:25Z","pmid":1,"year":"2021","publisher":"American Association for the Advancement of Science","publication_status":"published","article_processing_charge":"No","day":"03","scopus_import":"1","keyword":["Multidisciplinary"],"date_published":"2021-12-03T00:00:00Z","citation":{"ista":"Heck S, Baykusheva DR, Han M, Ji J-B, Perry C, Gong X, Wörner HJ. 2021.

We find delays of up to ∼600 as in the ionization out of the highest occupied molecular orbital (HOMO) with a strong dependence on the emission direction and a pronounced asymmetry along the dissociation axis. Comparison with quantum-scattering calculations traces the asymmetries to the interference of a small subset of partial waves at low kinetic energies and, additionally, to the interference of two overlapping shape resonances in the HOMO-1 channel.

The UVEX design has two co-aligned wide-field imagers operating in the FUV and NUV and a powerful broadband medium resolution spectrometer. In its two-year baseline mission, UVEX will perform a multi-cadence synoptic all-sky survey 50/100 times deeper than GALEX in the NUV/FUV, cadenced surveys of the Large and Small Magellanic Clouds, rapid target of opportunity followup, as well as spectroscopic followup of samples of stars and galaxies. The science program is built around three pillars. First, UVEX will explore the low-mass, low-metallicity galaxy frontier through imaging and spectroscopic surveys that will probe key aspects of the evolution of galaxies by understanding how star formation and stellar evolution at low metallicities affect the growth and evolution of low-metallicity, low-mass galaxies in the local universe. Such galaxies contain half the mass in the local universe, and are analogs for the first galaxies, but observed at distances that make them accessible to detailed study. Second, UVEX will explore the dynamic universe through time-domain surveys and prompt spectroscopic followup capability will probe the environments, energetics, and emission processes in the early aftermaths of gravitational wave-discovered compact object mergers, discover hot, fast UV transients, and diagnose the early stages of stellar explosions. Finally, UVEX will become a key community resource by leaving a large all-sky legacy data set, enabling a wide range of scientific studies and filling a gap in the new generation of wide-field, sensitive optical and infrared surveys provided by the Rubin, Euclid, and Roman observatories. This paper discusses the scientific potential of UVEX, and the broad scientific program."}],"extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"14097","year":"2021","publication_status":"submitted","status":"public","title":"Science with the ultraviolet explorer (UVEX)","author":[{"last_name":"Kulkarni","first_name":"S.

DQPTs are defined by nonanalyticities in the return amplitude and are present in many models. In some cases, DQPTs can be related to equilibrium concepts, such as order parameters, yet their universal description is an open question. In this Letter, we provide first steps toward a classification of DQPTs by using a matrix product state description of unitary dynamics in the thermodynamic limit. This allows us to distinguish the two limiting cases of “precession” and “entanglement” DQPTs, which are illustrated using an analytical description in the quantum Ising model. While precession DQPTs are characterized by a large entanglement gap and are semiclassical in their nature, entanglement DQPTs occur near avoided crossings in the entanglement spectrum and can be distinguished by a complex pattern of nonlocal correlations. We demonstrate the existence of precession and entanglement DQPTs beyond Ising models, discuss observables that can distinguish them, and relate their interplay to complex DQPT phenomenology.","lang":"eng"}]},{"external_id":{"pmid":["33930167"],"isi":["000703922000025"]},"tmp":{"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)","image":"/images/cc_by_nc_nd.png"},"oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/plphys/kiab199"}],"isi":1,"quality_controlled":"1","project":[{"name":"Long Term Fellowship","grant_number":"723-2015","_id":"256FEF10-B435-11E9-9278-68D0E5697425"},{"_id":"26538374-B435-11E9-9278-68D0E5697425","grant_number":"I03630","call_identifier":"FWF","name":"Molecular mechanisms of endocytic cargo recognition in plants"}],"doi":"10.1093/plphys/kiab199","language":[{"iso":"eng"}],"month":"04","publication_identifier":{"issn":["0032-0889"],"eissn":["1532-2548"]},"acknowledgement":"We gratefully acknowledge the Arabidopsis Biological Resource Centre (ABRC) for providing T-DNA insertional mutants, and Prof. Remko Offringa for sharing published seeds.

To elucidate the molecular mechanism of 3'-Phosphoinositide-Dependent Protein Kinase1 (PDK1), a master regulator that is essential throughout eukaryotic growth and development, we employed a forward genetic approach to screen for suppressors of the loss-of-function T-DNA insertion double mutant pdk1.1 pdk1.2 in Arabidopsis thaliana. Notably, the severe growth attenuation of pdk1.1 pdk1.2 was rescued by sop21 (suppressor of pdk1.1 pdk1.2), which harbours a loss-of-function mutation in PELOTA1 (PEL1). PEL1 is a homologue of mammalian PELOTA and yeast (Saccharomyces cerevisiae) DOM34p, which each form a heterodimeric complex with the GTPase HBS1 (HSP70 SUBFAMILY B SUPPRESSOR1, also called SUPERKILLER PROTEIN7, SKI7), a protein that is responsible for ribosomal rescue and thereby assures the quality and fidelity of mRNA molecules during translation. Genetic analysis further revealed that a dysfunctional PEL1-HBS1 complex failed to degrade the T-DNA-disrupted PDK1 transcripts, which were truncated but functional, and thus rescued the growth and developmental defects of pdk1.1 pdk1.2. Our studies demonstrated the functionality of a homologous PELOTA-HBS1 complex and identified its essential regulatory role in plants, providing insights into the mechanism of mRNA quality control."}],"issue":"4"},{"publication_identifier":{"issn":["0008-4395"],"eissn":["1496-4287"]},"month":"12","isi":1,"quality_controlled":"1","oa":1,"external_id":{"arxiv":["1804.10055"],"isi":["000730165300021"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1804.10055"}],"language":[{"iso":"eng"}],"doi":"10.4153/s000843952000096x","department":[{"_id":"UlWa"}],"publisher":"Canadian Mathematical Society","publication_status":"published","acknowledgement":"The author was supported by the Swiss National Science Foundation grant 200021_179133.

Arabidopsis mutants lacking PID, a kinase that phosphorylates PINs, or the MAB4/MEL proteins of unknown molecular function display PIN polarity defects and phenocopy pin mutants, but mechanistic insights into how these factors convey PIN polarity are missing. Here, by combining protein biochemistry with quantitative live-cell imaging, we demonstrate that PINs, MAB4/MELs, and AGC kinases interact in the same complex at the plasma membrane. MAB4/MELs are recruited to the plasma membrane by the PINs and in concert with the AGC kinases maintain PIN polarity through limiting lateral diffusion-based escape of PINs from the polar domain. The PIN-MAB4/MEL-PID protein complex has self-reinforcing properties thanks to positive feedback between AGC kinase-mediated PIN phosphorylation and MAB4/MEL recruitment. We thus uncover the molecular mechanism by which AGC kinases and MAB4/MEL proteins regulate PIN localization and plant development."}],"intvolume":" 31","title":"AGC kinases and MAB4/MEL proteins maintain PIN polarity by limiting lateral diffusion in plant cells","ddc":["580"],"status":"public","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"9290","oa_version":"Published Version","file":[{"file_id":"9303","relation":"main_file","date_created":"2021-04-01T10:53:42Z","date_updated":"2021-04-01T10:53:42Z","success":1,"checksum":"b1723040ecfd8c81194185472eb62546","file_name":"2021_CurrentBiology_Glanc.pdf","access_level":"open_access","creator":"dernst","content_type":"application/pdf","file_size":4324371}],"publication_identifier":{"issn":["0960-9822"],"eissn":["1879-0445"]},"month":"03","project":[{"_id":"261099A6-B435-11E9-9278-68D0E5697425","grant_number":"742985","call_identifier":"H2020","name":"Tracing Evolution of Auxin Transport and Polarity in Plants"},{"_id":"26538374-B435-11E9-9278-68D0E5697425","grant_number":"I03630","name":"Molecular mechanisms of endocytic cargo recognition in plants","call_identifier":"FWF"}],"quality_controlled":"1","isi":1,"external_id":{"pmid":["33705718"],"isi":["000653077800004"]},"tmp":{"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)","image":"/images/cc_by.png"},"oa":1,"language":[{"iso":"eng"}],"acknowledged_ssus":[{"_id":"Bio"}],"doi":"10.1016/j.cub.2021.02.028","ec_funded":1,"file_date_updated":"2021-04-01T10:53:42Z","publisher":"Elsevier","department":[{"_id":"JiFr"}],"publication_status":"published","pmid":1,"year":"2021","acknowledgement":"We acknowledge Ben Scheres, Christian Luschnig, and Claus Schwechheimer for sharing published material.

Here, we show that MEMBRANE ASSOCIATED KINASE REGULATOR2 (MAKR2) controls the pace of the root gravitropic response. We found that MAKR2 is required for the PIN2 asymmetry during gravitropism by acting as a negative regulator of the cell-surface signaling mediated by the receptor-like kinase TRANSMEMBRANE KINASE1 (TMK1).2,7, 8, 9, 10 Furthermore, we show that the MAKR2 inhibitory effect on TMK1 signaling is antagonized by auxin itself, which triggers rapid MAKR2 membrane dissociation in a TMK1-dependent manner. Our findings suggest that the timing of the root gravitropic response is orchestrated by the reversible inhibition of the TMK1 signaling pathway at the cell surface.","lang":"eng"}],"type":"journal_article","file":[{"relation":"main_file","file_id":"9090","checksum":"30b3393d841fb2b1e2b22fb42b5c8fff","success":1,"date_updated":"2021-02-04T11:37:50Z","date_created":"2021-02-04T11:37:50Z","access_level":"open_access","file_name":"2021_CurrentBiology_MarquesBueno.pdf","content_type":"application/pdf","file_size":3458646,"creator":"dernst"}],"oa_version":"Published Version","intvolume":" 31","status":"public","ddc":["570"],"title":"Auxin-regulated reversible inhibition of TMK1 signaling by MAKR2 modulates the dynamics of root gravitropism","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"8824","publication_identifier":{"issn":["0960-9822"],"eissn":["1879-0445"]},"month":"01","language":[{"iso":"eng"}],"doi":"10.1016/j.cub.2020.10.011","isi":1,"quality_controlled":"1","oa":1,"tmp":{"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)","image":"/images/cc_by.png"},"external_id":{"isi":["000614361000039"],"pmid":["33157019"]},"file_date_updated":"2021-02-04T11:37:50Z","volume":31,"date_created":"2020-12-01T13:39:46Z","date_updated":"2023-09-05T13:03:15Z","author":[{"last_name":"Marquès-Bueno","first_name":"MM","full_name":"Marquès-Bueno, MM"},{"first_name":"L","last_name":"Armengot","full_name":"Armengot, L"},{"last_name":"Noack","first_name":"LC","full_name":"Noack, LC"},{"full_name":"Bareille, J","first_name":"J","last_name":"Bareille"},{"id":"3922B506-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7244-7237","first_name":"Lesia","last_name":"Rodriguez Solovey","full_name":"Rodriguez Solovey, Lesia"},{"first_name":"MP","last_name":"Platre","full_name":"Platre, MP"},{"full_name":"Bayle, V","first_name":"V","last_name":"Bayle"},{"full_name":"Liu, M","first_name":"M","last_name":"Liu"},{"first_name":"D","last_name":"Opdenacker","full_name":"Opdenacker, D"},{"full_name":"Vanneste, S","first_name":"S","last_name":"Vanneste"},{"full_name":"Möller, BK","last_name":"Möller","first_name":"BK"},{"first_name":"ZL","last_name":"Nimchuk","full_name":"Nimchuk, ZL"},{"full_name":"Beeckman, T","first_name":"T","last_name":"Beeckman"},{"last_name":"Caño-Delgado","first_name":"AI","full_name":"Caño-Delgado, AI"},{"full_name":"Friml, Jiří","last_name":"Friml","first_name":"Jiří","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Y","last_name":"Jaillais","full_name":"Jaillais, Y"}],"department":[{"_id":"JiFr"}],"publisher":"Elsevier","publication_status":"published","pmid":1,"year":"2021","acknowledgement":"We thank the SiCE group for discussions and comments; S.

Current understanding states that the partition between surface adsorbed and dissolved lithium superoxide governs whether Li2O2 grows as a conformal surface film or larger particles, leading to low or high capacities, respectively. However, better understanding governing factors for Li2O2 packing density and capacity requires structural sensitive in situ metrologies. Here, we establish in situ small- and wide-angle X-ray scattering (SAXS/WAXS) as a suitable method to record the Li2O2 phase evolution with atomic to submicrometer resolution during cycling a custom-built in situ Li–O2 cell. Combined with sophisticated data analysis, SAXS allows retrieving rich quantitative structural information from complex multiphase systems. Surprisingly, we find that features are absent that would point at a Li2O2 surface film formed via two consecutive electron transfers, even in poorly solvating electrolytes thought to be prototypical for surface growth. All scattering data can be modeled by stacks of thin Li2O2 platelets potentially forming large toroidal particles. Li2O2 solution growth is further justified by rotating ring-disk electrode measurements and electron microscopy. Higher discharge overpotentials lead to smaller Li2O2 particles, but there is no transition to an electronically passivating, conformal Li2O2 coating. Hence, mass transport of reactive species rather than electronic transport through a Li2O2 film limits the discharge capacity. Provided that species mobilities and carbon surface areas are high, this allows for high discharge capacities even in weakly solvating electrolytes. The currently accepted Li–O2 reaction mechanism ought to be reconsidered."}],"issue":"14","_id":"9301","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","title":"In situ small-angle X-ray scattering reveals solution phase discharge of Li–O2 batteries with weakly solvating electrolytes","status":"public","intvolume":" 118","oa_version":"Preprint"},{"issue":"4","abstract":[{"lang":"eng","text":"Dendritic cells (DCs) are crucial for the priming of naive T cells and the initiation of adaptive immunity. Priming is initiated at a heterologous cell–cell contact, the immunological synapse (IS). While it is established that F-actin dynamics regulates signaling at the T cell side of the contact, little is known about the cytoskeletal contribution on the DC side. Here, we show that the DC actin cytoskeleton is decisive for the formation of a multifocal synaptic structure, which correlates with T cell priming efficiency. DC actin at the IS appears in transient foci that are dynamized by the WAVE regulatory complex (WRC). The absence of the WRC in DCs leads to stabilized contacts with T cells, caused by an increase in ICAM1-integrin–mediated cell–cell adhesion. This results in lower numbers of activated and proliferating T cells, demonstrating an important role for DC actin in the regulation of immune synapse functionality."}],"type":"journal_article","file":[{"access_level":"open_access","file_name":"2021_JournCellBiology_Leithner.pdf","file_size":5102328,"content_type":"application/pdf","creator":"dernst","relation":"main_file","file_id":"11367","checksum":"843ebc153847c8626e13c9c5ce71d533","success":1,"date_created":"2022-05-12T14:16:21Z","date_updated":"2022-05-12T14:16:21Z"}],"oa_version":"Published Version","_id":"9094","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","intvolume":" 220","ddc":["570"],"status":"public","title":"Dendritic cell actin dynamics control contact duration and priming efficiency at the immunological synapse","has_accepted_license":"1","article_processing_charge":"No","day":"05","scopus_import":"1","date_published":"2021-04-05T00:00:00Z","citation":{"ista":"Leithner AF, Altenburger L, Hauschild R, Assen FP, Rottner K, TEB S, Diz-Muñoz A, Stein J, Sixt MK. 2021.

One approach to determining how interactions between these circuit components give rise to complex behavior is to investigate the rules by which cortical circuits are formed and acquire functionality during development. This review summarizes recent research on the development of the neocortex, from genetic determination in neural stem cells through to the dynamic role that specific neuronal populations play in the earliest circuits of neocortex, and how they contribute to emergent function and cognition. While many of these endeavors take advantage of model systems, consideration will also be given to advances in our understanding of activity in nascent human circuits. Such cross-species perspective is imperative when investigating the mechanisms underlying the dysfunction of early neocortical circuits in neurodevelopmental disorders, so that one can identify targets amenable to therapeutic intervention."}],"_id":"9073","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","intvolume":" 41","title":"The logic of developing neocortical circuits in health and disease","status":"public","ddc":["570"],"file":[{"content_type":"application/pdf","file_size":1031150,"creator":"dernst","access_level":"open_access","file_name":"2021_JourNeuroscience_Hanganu.pdf","checksum":"578fd7ed1a0aef74bce61bea2d987b33","success":1,"date_updated":"2022-05-27T06:59:55Z","date_created":"2022-05-27T06:59:55Z","relation":"main_file","file_id":"11414"}],"oa_version":"Published Version"},{"date_published":"2021-08-17T00:00:00Z","article_type":"original","citation":{"mla":"Mondelli, Marco, et al. “Optimal Combination of Linear and Spectral Estimators for Generalized Linear Models.” Foundations of Computational Mathematics, Springer, 2021, doi:10.1007/s10208-021-09531-x.","short":"M.

Two popular solutions are based on a linear estimator 𝑥𝑥^L and a spectral estimator 𝑥𝑥^s. The former is a data-dependent linear combination of the columns of the measurement matrix, and its analysis is quite simple. The latter is the principal eigenvector of a data-dependent matrix, and a recent line of work has studied its performance. In this paper, we show how to optimally combine 𝑥𝑥^L and 𝑥𝑥^s. At the heart of our analysis is the exact characterization of the empirical joint distribution of (𝑥𝑥,𝑥𝑥^L,𝑥𝑥^s) in the high-dimensional limit. This allows us to compute the Bayes-optimal combination of 𝑥𝑥^L and 𝑥𝑥^s, given the limiting distribution of the signal 𝑥𝑥. When the distribution of the signal is Gaussian, then the Bayes-optimal combination has the form 𝜃𝑥𝑥^L+𝑥𝑥^s and we derive the optimal combination coefficient. In order to establish the limiting distribution of (𝑥𝑥,𝑥𝑥^L,𝑥𝑥^s), we design and analyze an approximate message passing algorithm whose iterates give 𝑥𝑥^L and approach 𝑥𝑥^s. Numerical simulations demonstrate the improvement of the proposed combination with respect to the two methods considered separately.","lang":"eng"}],"type":"journal_article","language":[{"iso":"eng"}],"doi":"10.1007/s10208-021-09531-x","project":[{"_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854","name":"IST Austria Open Access Fund"}],"isi":1,"quality_controlled":"1","tmp":{"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)","image":"/images/cc_by.png"},"oa":1,"external_id":{"arxiv":["2008.03326"],"isi":["000685721000001"]},"publication_identifier":{"issn":["1615-3375"],"eissn":["1615-3383"]},"month":"08","date_created":"2021-11-03T10:59:08Z","date_updated":"2023-09-05T14:13:57Z","author":[{"id":"27EB676C-8706-11E9-9510-7717E6697425","orcid":"0000-0002-3242-7020","first_name":"Marco","last_name":"Mondelli","full_name":"Mondelli, Marco"},{"first_name":"Christos","last_name":"Thrampoulidis","full_name":"Thrampoulidis, Christos"},{"full_name":"Venkataramanan, Ramji","first_name":"Ramji","last_name":"Venkataramanan"}],"publisher":"Springer","department":[{"_id":"MaMo"}],"publication_status":"published","year":"2021","acknowledgement":"M.

We first give a categorification of the mapper graph and the Reeb graph by interpreting them in terms of cosheaves and stratified covers of the real line R. We then introduce a variant of the classic mapper graph of Singh et al. (in: Eurographics symposium on point-based graphics, 2007), referred to as the enhanced mapper graph, and demonstrate that such a construction approximates the Reeb graph of (X,f) when it is applied to points randomly sampled from a probability density function concentrated on (X,f). Our techniques are based on the interleaving distance of constructible cosheaves and topological estimation via kernel density estimates. Following Munch and Wang (In: 32nd international symposium on computational geometry, volume 51 of Leibniz international proceedings in informatics (LIPIcs), Dagstuhl, Germany, pp 53:1–53:16, 2016), we first show that the mapper graph of (X,f), a constructible R-space (with a fixed open cover), approximates the Reeb graph of the same space. We then construct an isomorphism between the mapper of (X,f) to the mapper of a super-level set of a probability density function concentrated on (X,f). Finally, building on the approach of Bobrowski et al. (Bernoulli 23(1):288–328, 2017b), we show that, with high probability, we can recover the mapper of the super-level set given a sufficiently large sample. Our work is the first to consider the mapper construction using the theory of cosheaves in a probabilistic setting. It is part of an ongoing effort to combine sheaf theory, probability, and statistics, to support topological data analysis with random data.","lang":"eng"}],"issue":"1","type":"journal_article"},{"intvolume":" 75","status":"public","title":"Polygenic local adaptation in metapopulations: A stochastic eco‐evolutionary model","ddc":["570"],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"9252","file":[{"creator":"kschuh","content_type":"application/pdf","file_size":734102,"access_level":"open_access","file_name":"2021_Evolution_Szep.pdf","success":1,"checksum":"b90fb5767d623602046fed03725e16ca","date_created":"2021-08-11T13:39:19Z","date_updated":"2021-08-11T13:39:19Z","file_id":"9886","relation":"main_file"}],"oa_version":"Published Version","type":"journal_article","issue":"5","abstract":[{"lang":"eng","text":"This paper analyses the conditions for local adaptation in a metapopulation with infinitely many islands under a model of hard selection, where population size depends on local fitness.

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.

One possible constraint is the opportunity for allopatric divergence. In 1981, Felsenstein used a simple and elegant model to ask if there might also be genetic constraints. He showed that progress towards speciation could be described by the build‐up of linkage disequilibrium among divergently selected loci and between these loci and those contributing to other forms of reproductive isolation. Therefore, speciation is opposed by recombination, because it tends to break down linkage disequilibria. Felsenstein then introduced a crucial distinction between “two‐allele” models, which are subject to this effect, and “one‐allele” models, which are free from the recombination constraint. These fundamentally important insights have been the foundation for both empirical and theoretical studies of speciation ever since.","lang":"eng"}],"intvolume":" 75","status":"public","title":"Homage to Felsenstein 1981, or why are there so few/many species?","_id":"9374","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"Published Version","keyword":["Genetics","Ecology","Evolution","Behavior and Systematics","General Agricultural and Biological Sciences"],"article_processing_charge":"No","day":"19","page":"978-988","article_type":"original","citation":{"ama":"Butlin RK, Servedio MR, Smadja CM, et al.

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."}],"license":"https://creativecommons.org/publicdomain/zero/1.0/","_id":"13062","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2021","ddc":["570"],"title":"Supplementary code for: Polygenic local adaptation in metapopulations: A stochastic eco-evolutionary model","status":"public","publisher":"Dryad","department":[{"_id":"NiBa"}],"author":[{"full_name":"Szep, Eniko","id":"485BB5A4-F248-11E8-B48F-1D18A9856A87","last_name":"Szep","first_name":"Eniko"},{"full_name":"Sachdeva, Himani","last_name":"Sachdeva","first_name":"Himani","id":"42377A0A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Barton, Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8548-5240","first_name":"Nicholas H","last_name":"Barton"}],"related_material":{"record":[{"id":"9252","relation":"used_in_publication","status":"public"}]},"date_updated":"2023-09-05T15:44:05Z","date_created":"2023-05-23T16:17:02Z","oa_version":"Published Version"},{"publication_identifier":{"eissn":["1365-294X"],"issn":["0962-1083"]},"month":"08","language":[{"iso":"eng"}],"doi":"10.1111/mec.15861","isi":1,"quality_controlled":"1","external_id":{"pmid":["33638231"],"isi":["000669439700001"]},"tmp":{"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)","image":"/images/cc_by.png"},"oa":1,"file_date_updated":"2022-03-08T11:31:30Z","volume":30,"date_created":"2022-03-08T11:28:32Z","date_updated":"2023-09-05T16:02:19Z","author":[{"first_name":"Anja M","last_name":"Westram","id":"3C147470-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-1050-4969","full_name":"Westram, Anja M"},{"full_name":"Faria, Rui","last_name":"Faria","first_name":"Rui"},{"last_name":"Johannesson","first_name":"Kerstin","full_name":"Johannesson, Kerstin"},{"first_name":"Roger","last_name":"Butlin","full_name":"Butlin, Roger"}],"publisher":"Wiley","department":[{"_id":"BeVi"}],"publication_status":"published","pmid":1,"year":"2021","acknowledgement":"We thank everyone who helped with fieldwork, snail processing and DNA extractions, particularly Laura Brettell, Mårten Duvetorp, Juan Galindo, Anne-Lise Liabot, Mark Ravinet, Irena Senčić and Zuzanna Zagrodzka.

It allows for the identification of genomic regions underlying barriers to gene flow. It also provides insights into spatial patterns of allele frequency change, informing about the interplay between environmental factors, dispersal and selection. However, when only a single hybrid zone is analysed, it is difficult to separate patterns generated by selection from those resulting from chance. Therefore, it is beneficial to look for repeatable patterns across replicate hybrid zones in the same system. We applied this approach to the marine snail Littorina saxatilis, which contains two ecotypes, adapted to wave-exposed rocks vs. high-predation boulder fields. The existence of numerous hybrid zones between ecotypes offered the opportunity to test for the repeatability of genomic architectures and spatial patterns of divergence. We sampled and phenotyped snails from seven replicate hybrid zones on the Swedish west coast and genotyped them for thousands of single nucleotide polymorphisms. Shell shape and size showed parallel clines across all zones. Many genomic regions showing steep clines and/or high differentiation were shared among hybrid zones, consistent with a common evolutionary history and extensive gene flow between zones, and supporting the importance of these regions for divergence. In particular, we found that several large putative inversions contribute to divergence in all locations. Additionally, we found evidence for consistent displacement of clines from the boulder–rock transition. Our results demonstrate patterns of spatial variation that would not be accessible without continuous spatial sampling, a large genomic data set and replicate hybrid zones."}],"type":"journal_article","file":[{"relation":"main_file","file_id":"10839","checksum":"d5611f243ceb63a0e091d6662ebd9cda","success":1,"date_updated":"2022-03-08T11:31:30Z","date_created":"2022-03-08T11:31:30Z","access_level":"open_access","file_name":"2021_MolecularEcology_Westram.pdf","content_type":"application/pdf","file_size":1726548,"creator":"dernst"}],"oa_version":"Published Version","intvolume":" 30","title":"Using replicate hybrid zones to understand the genomic basis of adaptive divergence","status":"public","ddc":["570"],"_id":"10838","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1"},{"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"9288","intvolume":" 230","title":"Seedling developmental defects upon blocking CINNAMATE-4-HYDROXYLASE are caused by perturbations in auxin transport","status":"public","oa_version":"Published Version","type":"journal_article","issue":"6","abstract":[{"lang":"eng","text":"• The phenylpropanoid pathway serves a central role in plant metabolism, providing numerous compounds involved in diverse physiological processes.

Growth-promoting hormones and defence signalling fine tune plant development antagonistically. During host-pathogen interactions, this defence-growth trade-off is mediated by the counteractive effects of the defence hormone salicylic acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism of SA regulating auxin signalling by constraining the plasma membrane dynamics of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation. Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced heterogeneous surface condensation disrupted asymmetric auxin distribution and the resultant gravitropic response. Our results demonstrated a defence-growth trade-off mechanism by which SA signalling crosstalked with auxin transport by concentrating membrane-resident PIN2 into heterogeneous compartments.","lang":"eng"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"8608","intvolume":" 229","ddc":["580"],"title":"Salicylic acid regulates PIN2 auxin transporter hyper-clustering and root gravitropic growth via Remorin-dependent lipid nanodomain organization in Arabidopsis thaliana","status":"public","oa_version":"Published Version","file":[{"relation":"main_file","file_id":"9085","checksum":"d36b6a8c6fafab66264e0d27114dae63","success":1,"date_created":"2021-02-04T09:53:16Z","date_updated":"2021-02-04T09:53:16Z","access_level":"open_access","file_name":"2021_NewPhytologist_Ke.pdf","content_type":"application/pdf","file_size":3674502,"creator":"dernst"}],"scopus_import":"1","has_accepted_license":"1","article_processing_charge":"No","day":"01","citation":{"apa":"Ke, M., Ma, Z., Wang, D., Sun, Y., Wen, C., Huang, D., … Chen, X.

The k-fold cover for some discrete input point set consists of the space where at least k balls of radius r around the input points overlap. Persistence is a notion that captures, in some sense, the topology of the shape underlying the input. While persistence is usually computed for the union of balls, the k-fold cover is of interest as it captures local density,\r\nand thus might approximate the shape of the input better if the input data is noisy. To compute persistence of these k-fold covers, we need a discretization that is provided by higher-order Delaunay mosaics. We present and implement a simple and efficient algorithm for the computation of higher-order Delaunay mosaics, and use it to give experimental results for their combinatorial properties. The algorithm makes use of a new geometric structure, the rhomboid tiling. It contains the higher-order Delaunay mosaics as slices, and by introducing a filtration\r\nfunction on the tiling, we also obtain higher-order α-shapes as slices. These allow us to compute persistence of the multi-covers for varying radius r; the computation for varying k is less straight-foward and involves the rhomboid tiling directly. We apply our algorithms to experimental sphere packings to shed light on their structural properties. Finally, inspired by periodic structures in packings and materials, we propose and implement an algorithm for periodic Delaunay triangulations to be integrated into the Computational Geometry Algorithms Library (CGAL), and discuss the implications on persistence for periodic data sets."}],"ddc":["006","514","516"],"status":"public","title":"Multi-cover persistence and Delaunay mosaics","_id":"9056","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file":[{"relation":"source_file","file_id":"9063","date_created":"2021-02-02T14:09:25Z","date_updated":"2021-02-03T10:37:28Z","checksum":"bcf27986147cab0533b6abadd74e7629","file_name":"thesis_source.zip","access_level":"closed","content_type":"application/zip","file_size":13446994,"creator":"patrickd"},{"relation":"main_file","file_id":"9064","checksum":"9cc8af266579a464385bbe2aff6af606","success":1,"date_updated":"2021-02-02T14:09:18Z","date_created":"2021-02-02T14:09:18Z","access_level":"open_access","file_name":"thesis_pdfA2b.pdf","content_type":"application/pdf","file_size":5210329,"creator":"patrickd"}],"oa_version":"Published Version"},{"file":[{"creator":"gcipollo","file_size":4127796,"content_type":"application/pdf","file_name":"thesis.pdf","access_level":"open_access","date_created":"2021-01-25T14:19:03Z","date_updated":"2021-01-25T14:19:03Z","success":1,"checksum":"5a93658a5f19478372523ee232887e2b","file_id":"9043","relation":"main_file"},{"checksum":"e8270eddfe6a988e92a53c88d1d19b8c","date_updated":"2021-01-25T14:19:10Z","date_created":"2021-01-25T14:19:10Z","file_id":"9044","relation":"source_file","creator":"gcipollo","content_type":"application/zip","file_size":12775206,"access_level":"closed","file_name":"Thesis_files.zip"}],"oa_version":"Published Version","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"9022","ddc":["510"],"title":"Fluctuations in the spectrum of random matrices","status":"public","abstract":[{"text":"In the first part of the thesis we consider Hermitian random matrices. Firstly, we consider sample covariance matrices XX∗ with X having independent identically distributed (i.i.d.) centred entries. We prove a Central Limit Theorem for differences of linear statistics of XX∗ and its minor after removing the first column of X. Secondly, we consider Wigner-type matrices and prove that the eigenvalue statistics near cusp singularities of the limiting density of states are universal and that they form a Pearcey process. Since the limiting eigenvalue distribution admits only square root (edge) and cubic root (cusp) singularities, this concludes the third and last remaining case of the Wigner-Dyson-Mehta universality conjecture. The main technical ingredients are an optimal local law at the cusp, and the proof of the fast relaxation to equilibrium of the Dyson Brownian motion in the cusp regime.\r\nIn the second part we consider non-Hermitian matrices X with centred i.i.d. entries. We normalise the entries of X to have variance N −1. It is well known that the empirical eigenvalue density converges to the uniform distribution on the unit disk (circular law). In the first project, we prove universality of the local eigenvalue statistics close to the edge of the spectrum. This is the non-Hermitian analogue of the TracyWidom universality at the Hermitian edge. Technically we analyse the evolution of the spectral distribution of X along the Ornstein-Uhlenbeck flow for very long time\r\n(up to t = +∞). In the second project, we consider linear statistics of eigenvalues for macroscopic test functions f in the Sobolev space H2+ϵ and prove their convergence to the projection of the Gaussian Free Field on the unit disk. We prove this result for non-Hermitian matrices with real or complex entries. The main technical ingredients are: (i) local law for products of two resolvents at different spectral parameters, (ii) analysis of correlated Dyson Brownian motions.\r\nIn the third and final part we discuss the mathematically rigorous application of supersymmetric techniques (SUSY ) to give a lower tail estimate of the lowest singular value of X − z, with z ∈ C. More precisely, we use superbosonisation formula to give an integral representation of the resolvent of (X − z)(X − z)∗ which reduces to two and three contour integrals in the complex and real case, respectively. The rigorous analysis of these integrals is quite challenging since simple saddle point analysis cannot be applied (the main contribution comes from a non-trivial manifold). Our result\r\nimproves classical smoothing inequalities in the regime |z| ≈ 1; this result is essential to prove edge universality for i.i.d. non-Hermitian matrices.","lang":"eng"}],"type":"dissertation","alternative_title":["ISTA Thesis"],"date_published":"2021-01-25T00:00:00Z","citation":{"ama":"Cipolloni G.

As scheduling non-determinism creates exponentially large spaces of thread interleavings, SMC attempts to partition this space into equivalence classes and explore only a few representatives from each class. The efficiency of this approach depends on two factors: (a) the coarseness of the partitioning, and (b) the time to generate representatives in each class. For this reason, the search for coarse partitionings that are efficiently explorable is an active research challenge. In this work we present RVF-SMC , a new SMC algorithm that uses a novel reads-value-from (RVF) partitioning. Intuitively, two interleavings are deemed equivalent if they agree on the value obtained in each read event, and read events induce consistent causal orderings between them. The RVF partitioning is provably coarser than recent approaches based on Mazurkiewicz and “reads-from” partitionings. Our experimental evaluation reveals that RVF is quite often a very effective equivalence, as the underlying partitioning is exponentially coarser than other approaches. Moreover, RVF-SMC generates representatives very efficiently, as the reduction in the partitioning is often met with significant speed-ups in the model checking task.","lang":"eng"}],"alternative_title":["LNCS"],"type":"conference"},{"related_material":{"record":[{"id":"10012","status":"public","relation":"part_of_dissertation"},{"status":"public","relation":"part_of_dissertation","id":"10013"},{"relation":"part_of_dissertation","status":"public","id":"7489"}]},"author":[{"first_name":"Sebastian","last_name":"Hensel","id":"4D23B7DA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7252-8072","full_name":"Hensel, Sebastian"}],"date_created":"2021-09-13T11:12:34Z","date_updated":"2023-09-07T13:30:45Z","year":"2021","department":[{"_id":"GradSch"},{"_id":"JuFi"}],"publisher":"Institute of Science and Technology Austria","publication_status":"published","ec_funded":1,"file_date_updated":"2021-09-15T14:37:30Z","doi":"10.15479/at:ista:10007","language":[{"iso":"eng"}],"degree_awarded":"PhD","supervisor":[{"full_name":"Fischer, Julian L","id":"2C12A0B0-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0479-558X","first_name":"Julian L","last_name":"Fischer"}],"oa":1,"project":[{"call_identifier":"H2020","name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385"},{"call_identifier":"H2020","name":"Bridging Scales in Random Materials","grant_number":"948819","_id":"0aa76401-070f-11eb-9043-b5bb049fa26d"}],"publication_identifier":{"issn":["2663-337X"]},"month":"09","file":[{"checksum":"c8475faaf0b680b4971f638f1db16347","date_created":"2021-09-13T11:03:24Z","date_updated":"2021-09-15T14:37:30Z","file_id":"10008","relation":"source_file","creator":"shensel","file_size":15022154,"content_type":"application/x-zip-compressed","access_level":"closed","file_name":"thesis_final_Hensel.zip"},{"date_updated":"2021-09-14T09:52:47Z","date_created":"2021-09-13T14:18:56Z","checksum":"1a609937aa5275452822f45f2da17f07","file_id":"10014","relation":"main_file","creator":"shensel","file_size":6583638,"content_type":"application/pdf","file_name":"thesis_final_Hensel.pdf","access_level":"open_access"}],"oa_version":"Published Version","_id":"10007","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","status":"public","ddc":["515"],"title":"Curvature driven interface evolution: Uniqueness properties of weak solution concepts","abstract":[{"lang":"eng","text":"The present thesis is concerned with the derivation of weak-strong uniqueness principles for curvature driven interface evolution problems not satisfying a comparison principle. The specific examples being treated are two-phase Navier-Stokes flow with surface tension, modeling the evolution of two incompressible, viscous and immiscible fluids separated by a sharp interface, and multiphase mean curvature flow, which serves as an idealized model for the motion of grain boundaries in an annealing polycrystalline material. Our main results - obtained in joint works with Julian Fischer, Tim Laux and Theresa M. Simon - state that prior to the formation of geometric singularities due to topology changes, the weak solution concept of Abels (Interfaces Free Bound. 9, 2007) to two-phase Navier-Stokes flow with surface tension and the weak solution concept of Laux and Otto (Calc. Var. Partial Differential Equations 55, 2016) to multiphase mean curvature flow (for networks in R^2 or double bubbles in R^3) represents the unique solution to these interface evolution problems within the class of classical solutions, respectively. To the best of the author's knowledge, for interface evolution problems not admitting a geometric comparison principle the derivation of a weak-strong uniqueness principle represented an open problem, so that the works contained in the present thesis constitute the first positive results in this direction. The key ingredient of our approach consists of the introduction of a novel concept of relative entropies for a class of curvature driven interface evolution problems, for which the associated energy contains an interfacial contribution being proportional to the surface area of the evolving (network of) interface(s). The interfacial part of the relative entropy gives sufficient control on the interface error between a weak and a classical solution, and its time evolution can be computed, at least in principle, for any energy dissipating weak solution concept. A resulting stability estimate for the relative entropy essentially entails the above mentioned weak-strong uniqueness principles. The present thesis contains a detailed introduction to our relative entropy approach, which in particular highlights potential applications to other problems in curvature driven interface evolution not treated in this thesis."}],"type":"dissertation","alternative_title":["ISTA Thesis"],"date_published":"2021-09-14T00:00:00Z","citation":{"chicago":"Hensel, Sebastian. “Curvature Driven Interface Evolution: Uniqueness Properties of Weak Solution Concepts.” Institute of Science and Technology Austria, 2021. https://doi.org/10.15479/at:ista:10007.","short":"S.

Moreover, based on our solution to these problems, we develop an SMC algorithm under TSO and PSO that uses the RF equivalence. The algorithm is exploration-optimal, in the sense that it is guaranteed to explore each class of the RF partitioning exactly once, and spends polynomial time per class when k is bounded. Finally, we implement all our algorithms in the SMC tool Nidhugg, and perform a large number of experiments over benchmarks from existing literature. Our experimental results show that our algorithms for VTSO-rf and VPSO-rf provide significant scalability improvements over standard alternatives. Moreover, when used for SMC, the RF partitioning is often much coarser than the standard Shasha-Snir partitioning for TSO/PSO, which yields a significant speedup in the model checking task.\r\n\r\n"}],"intvolume":" 5","ddc":["000"],"title":"The reads-from equivalence for the TSO and PSO memory models","status":"public","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","_id":"10191","oa_version":"Published Version","file":[{"date_updated":"2021-11-04T07:24:48Z","date_created":"2021-11-04T07:24:48Z","success":1,"checksum":"9d6dce7b611853c529bb7b1915ac579e","file_id":"10215","relation":"main_file","creator":"cchlebak","content_type":"application/pdf","file_size":2903485,"file_name":"2021_ProcACMPL_Bui.pdf","access_level":"open_access"}]},{"language":[{"iso":"eng"}],"date_published":"2021-08-03T00:00:00Z","doi":"10.48550/arXiv.2108.01733","project":[{"call_identifier":"H2020","name":"Bridging Scales in Random Materials","_id":"0aa76401-070f-11eb-9043-b5bb049fa26d","grant_number":"948819"}],"citation":{"ama":"Hensel S, Laux T.

More in detail, my research focuses on the study of transport costs on graphs, in particular the convergence and the stability of such problems in the discrete-to-continuum limit. This thesis also includes some results concerning\r\nnon-commutative optimal transport. The first chapter of this thesis consists of a general introduction to the optimal transport problems, both in the discrete, the continuous, and the non-commutative setting. Chapters 2 and 3 present the content of two works, obtained in collaboration with Peter Gladbach, Eva Kopfer, and Jan Maas, where we have been able to show the convergence of discrete transport costs on periodic graphs to suitable continuous ones, which can be described by means of a homogenisation result. We first focus on the particular case of quadratic costs on the real line and then extending the result to more general costs in arbitrary dimension. Our results are the first complete characterisation of limits of transport costs on periodic graphs in arbitrary dimension which do not rely on any additional symmetry. In Chapter 4 we turn our attention to one of the intriguing connection between evolution equations and optimal transport, represented by the theory of gradient flows. We show that discrete gradient flow structures associated to a finite volume approximation of a certain class of diffusive equations (Fokker–Planck) is stable in the limit of vanishing meshes, reproving the convergence of the scheme via the method of evolutionary Γ-convergence and exploiting a more variational point of view on the problem. This is based on a collaboration with Dominik Forkert and Jan Maas. Chapter 5 represents a change of perspective, moving away from the discrete world and reaching the non-commutative one. As in the discrete case, we discuss how classical tools coming from the commutative optimal transport can be translated into the setting of density matrices. In particular, in this final chapter we present a non-commutative version of the Schrödinger problem (or entropic regularised optimal transport problem) and discuss existence and characterisation of minimisers, a duality result, and present a non-commutative version of the well-known Sinkhorn algorithm to compute the above mentioned optimisers. This is based on a joint work with Dario Feliciangeli and Augusto Gerolin. Finally, Appendix A and B contain some additional material and discussions, with particular attention to Harnack inequalities and the regularity of flows on discrete spaces.","lang":"eng"}],"ddc":["515"],"title":"Discrete-to-continuum limits of transport problems and gradient flows in the space of measures","status":"public","_id":"10030","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","file":[{"relation":"source_file","file_id":"10032","date_created":"2021-09-21T09:17:34Z","date_updated":"2022-03-10T12:14:42Z","checksum":"8cd60dcb8762e8f21867e21e8001e183","file_name":"tex_and_pictures.zip","access_level":"closed","file_size":3876668,"content_type":"application/x-zip-compressed","creator":"cchlebak"},{"date_updated":"2021-09-27T11:14:31Z","date_created":"2021-09-27T11:14:31Z","checksum":"9789e9d967c853c1503ec7f307170279","relation":"main_file","file_id":"10047","content_type":"application/pdf","file_size":2532673,"creator":"cchlebak","file_name":"thesis_portinale_Final (1).pdf","access_level":"open_access"}],"oa_version":"Published Version","publication_identifier":{"issn":["2663-337X"]},"month":"09","project":[{"call_identifier":"FWF","name":"Dissipation and Dispersion in Nonlinear Partial Differential Equations","_id":"260788DE-B435-11E9-9278-68D0E5697425"},{"name":"Taming Complexity in Partial Differential Systems","_id":"fc31cba2-9c52-11eb-aca3-ff467d239cd2","grant_number":"F6504"}],"tmp":{"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)","image":"/images/cc_by.png"},"oa":1,"language":[{"iso":"eng"}],"supervisor":[{"last_name":"Maas","first_name":"Jan","orcid":"0000-0002-0845-1338","id":"4C5696CE-F248-11E8-B48F-1D18A9856A87","full_name":"Maas, Jan"}],"degree_awarded":"PhD","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"doi":"10.15479/at:ista:10030","file_date_updated":"2022-03-10T12:14:42Z","publisher":"Institute of Science and Technology Austria","department":[{"_id":"GradSch"},{"_id":"JaMa"}],"publication_status":"published","acknowledgement":"The author gratefully acknowledges support by the Austrian Science Fund (FWF), grants No W1245.","year":"2021","date_created":"2021-09-21T09:14:15Z","date_updated":"2023-09-07T13:31:06Z","related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"10022"},{"status":"public","relation":"part_of_dissertation","id":"9792"},{"id":"7573","relation":"part_of_dissertation","status":"public"}]},"author":[{"first_name":"Lorenzo","last_name":"Portinale","id":"30AD2CBC-F248-11E8-B48F-1D18A9856A87","full_name":"Portinale, Lorenzo"}]},{"title":"Geometric superinductors and their applications in circuit quantum electrodynamics","status":"public","ddc":["539"],"_id":"9920","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"Published Version","file":[{"file_id":"9924","relation":"source_file","date_created":"2021-08-16T09:33:21Z","date_updated":"2021-09-06T08:39:47Z","checksum":"3cd1986efde5121d7581f6fcf9090da8","file_name":"GeometricSuperinductorsForCQED.zip","access_level":"closed","creator":"mperuzzo","file_size":151387283,"content_type":"application/x-zip-compressed"},{"date_created":"2021-08-18T14:20:06Z","date_updated":"2021-09-06T08:39:47Z","checksum":"50928c621cdf0775d7a5906b9dc8602c","file_id":"9939","relation":"main_file","creator":"mperuzzo","file_size":17596344,"content_type":"application/pdf","file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-1b.pdf","access_level":"open_access"},{"checksum":"37f486aa1b622fe44af00d627ec13f6c","date_created":"2021-08-18T14:20:09Z","date_updated":"2021-09-06T08:39:47Z","file_id":"9940","relation":"other","creator":"mperuzzo","file_size":17592425,"content_type":"application/pdf","access_level":"closed","description":"Extra copy of the thesis as PDF/A-2b","file_name":"GeometricSuperinductorsAndTheirApplicationsIncQED-2b.pdf"}],"alternative_title":["ISTA Thesis"],"type":"dissertation","abstract":[{"text":"This work is concerned with two fascinating circuit quantum electrodynamics components, the Josephson junction and the geometric superinductor, and the interesting experiments that can be done by combining the two. The Josephson junction has revolutionized the field of superconducting circuits as a non-linear dissipation-less circuit element and is used in almost all superconducting qubit implementations since the 90s. On the other hand, the superinductor is a relatively new circuit element introduced as a key component of the fluxonium qubit in 2009. This is an inductor with characteristic impedance larger than the resistance quantum and self-resonance frequency in the GHz regime. The combination of these two elements can occur in two fundamental ways: in parallel and in series. When connected in parallel the two create the fluxonium qubit, a loop with large inductance and a rich energy spectrum reliant on quantum tunneling. On the other hand placing the two elements in series aids with the measurement of the IV curve of a single Josephson junction in a high impedance environment. In this limit theory predicts that the junction will behave as its dual element: the phase-slip junction. While the Josephson junction acts as a non-linear inductor the phase-slip junction has the behavior of a non-linear capacitance and can be used to measure new Josephson junction phenomena, namely Coulomb blockade of Cooper pairs and phase-locked Bloch oscillations. The latter experiment allows for a direct link between frequency and current which is an elusive connection in quantum metrology. This work introduces the geometric superinductor, a superconducting circuit element where the high inductance is due to the geometry rather than the material properties of the superconductor, realized from a highly miniaturized superconducting planar coil. These structures will be described and characterized as resonators and qubit inductors and progress towards the measurement of phase-locked Bloch oscillations will be presented.","lang":"eng"}],"page":"149","citation":{"short":"M.

Most of these models are trained employing variants of stochastic gradient descent (SGD) based optimization, but most methods involve some type of consistency relaxation relative to sequential SGD, to mitigate its large communication or synchronization costs at scale. In this paper, we introduce a general consistency condition covering communication-reduced and asynchronous distributed SGD implementations. Our framework, called elastic consistency, decouples the system-specific aspects of the implementation from the SGD convergence requirements, giving a general way to obtain convergence bounds for a wide variety of distributed SGD methods used in practice. Elastic consistency can be used to re-derive or improve several previous convergence bounds in message-passing and shared-memory settings, but also to analyze new models and distribution schemes. As a direct application, we propose and analyze a new synchronization-avoiding scheduling scheme for distributed SGD, and show that it can be used to efficiently train deep convolutional models for image classification.","lang":"eng"}],"type":"conference","oa_version":"Published Version","intvolume":" 35","title":"Elastic consistency: A practical consistency model for distributed stochastic gradient descent","status":"public","_id":"10432","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","article_processing_charge":"No","day":"18","date_published":"2021-05-18T00:00:00Z","page":"9037-9045","citation":{"apa":"Nadiradze, G., Markov, I., Chatterjee, B., Kungurtsev, V., & Alistarh, D.-A.

Lindell and Pinkas (Journal of Cryptograhy 2009) gave a formal proof of security in the selective setting where the adversary chooses the challenge inputs before seeing the garbled circuit assuming secure symmetric-key encryption (and hence one-way functions). This was followed by results, both positive and negative, concerning its security in the, stronger, adaptive setting. Applebaum et al. (Crypto 2013) showed that it cannot satisfy adaptive security as is, due to a simple incompressibility argument. Jafargholi and Wichs (TCC 2017) considered a natural adaptation of Yao’s scheme (where the output mapping is sent in the online phase, together with the garbled input) that circumvents this negative result, and proved that it is adaptively secure, at least for shallow circuits. In particular, they showed that for the class of circuits of depth δ , the loss in security is at most exponential in δ . The above results all concern the simulation-based notion of security. In this work, we show that the upper bound of Jafargholi and Wichs is basically optimal in a strong sense. As our main result, we show that there exists a family of Boolean circuits, one for each depth δ∈N , such that any black-box reduction proving the adaptive indistinguishability of the natural adaptation of Yao’s scheme from any symmetric-key encryption has to lose a factor that is exponential in δ√ . Since indistinguishability is a weaker notion than simulation, our bound also applies to adaptive simulation. To establish our results, we build on the recent approach of Kamath et al. (Eprint 2021), which uses pebbling lower bounds in conjunction with oracle separations to prove fine-grained lower bounds on loss in cryptographic security."}],"citation":{"chicago":"Kamath Hosdurg, Chethan, Karen Klein, Krzysztof Z Pietrzak, and Daniel Wichs. “Limits on the Adaptive Security of Yao’s Garbling.” In 41st Annual International Cryptology Conference, Part II , 12826:486–515.

The two existing proposals to date are ART (Cohn-Gordon et al., CCS18) and TreeKEM (IETF, The Messaging Layer Security Protocol, draft). TreeKEM is the currently considered candidate by the IETF MLS working group, but dynamic group operations (i.e. adding and removing users) can cause efficiency issues. In this paper we formalize and analyze a variant of TreeKEM which we term Tainted TreeKEM (TTKEM for short). The basic idea underlying TTKEM was suggested by Millican (MLS mailing list, February 2018). This version is more efficient than TreeKEM for some natural distributions of group operations, we quantify this through simulations.Our second contribution is two security proofs for TTKEM which establish post compromise and forward secrecy even against adaptive attackers. The security loss (to the underlying PKE) in the Random Oracle Model is a polynomial factor, and a quasipolynomial one in the Standard Model. Our proofs can be adapted to TreeKEM as well. Before our work no security proof for any TreeKEM-like protocol establishing tight security against an adversary who can adaptively choose the sequence of operations was known. We also are the first to prove (or even formalize) active security where the server can arbitrarily deviate from the protocol specification. Proving fully active security – where also the users can arbitrarily deviate – remains open."}]},{"oa_version":"Preprint","date_created":"2021-09-24T12:01:34Z","date_updated":"2023-09-07T13:32:11Z","related_material":{"record":[{"relation":"later_version","status":"public","id":"10409"},{"id":"10035","status":"public","relation":"dissertation_contains"}]},"author":[{"id":"4BD3F30E-F248-11E8-B48F-1D18A9856A87","last_name":"Kamath Hosdurg","first_name":"Chethan","full_name":"Kamath Hosdurg, Chethan"},{"full_name":"Klein, Karen","first_name":"Karen","last_name":"Klein","id":"3E83A2F8-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Pietrzak, Krzysztof Z","last_name":"Pietrzak","first_name":"Krzysztof Z","orcid":"0000-0002-9139-1654","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87"}],"publisher":"International Association for Cryptologic Research","department":[{"_id":"KrPi"}],"publication_status":"published","status":"public","title":"On treewidth, separators and Yao's garbling","_id":"10044","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","acknowledgement":"We would like to thank Daniel Wichs for helpful discussions on the landscape of adaptive security of Yao’s garbling.

However, they will find out that some approaches can exist only conceptually without high chances to become practically useful. It seems that a numerical technique called automatic differentiation together with increasing supply of computational accelerators will soon shift many methods of the material design from the category ”unimaginable” to the category ”expensive but possible”. Approach we suggest is not an exception. Our overall goal is to have an efficient and generalizable approach allowing to solve inverse design problems. In this thesis we scratch its surface. We consider jammed systems of identical particles. And ask ourselves how the shape of those particles (or the parameters codifying it) may affect mechanical properties of the system. An indispensable part of reaching the answer is an appropriate particle parametrization. We come up with a simple, yet generalizable and purposeful scheme for it. Using our generalizable shape parameterization, we simulate the formation of a solid composed of pentagonal-like particles and measure anisotropy in the resulting elastic response. Through automatic differentiation techniques, we directly connect the shape parameters with the elastic response. Interestingly, for our system we find that less isotropic particles lead to a more isotropic elastic response. Together with other results known about our method it seems that it can be successfully generalized for different inverse design problems."}]},{"year":"2021","_id":"10803","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"ChLa"}],"publication_status":"submitted","title":"Fairness through regularization for learning to rank","status":"public","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"10799"}]},"author":[{"full_name":"Konstantinov, Nikola H","last_name":"Konstantinov","first_name":"Nikola H","id":"4B9D76E4-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0002-4561-241X","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","last_name":"Lampert","first_name":"Christoph","full_name":"Lampert, Christoph"}],"oa_version":"Preprint","date_created":"2022-02-28T14:13:59Z","date_updated":"2023-09-07T13:42:08Z","type":"preprint","article_number":"2102.05996","abstract":[{"text":"Given the abundance of applications of ranking in recent years, addressing fairness concerns around automated ranking systems becomes necessary for increasing the trust among end-users. Previous work on fair ranking has mostly focused on application-specific fairness notions, often tailored to online advertising, and it rarely considers learning as part of the process. In this work, we show how to transfer numerous fairness notions from binary classification to a learning to rank setting. Our formalism allows us to design methods for incorporating fairness objectives with provable generalization guarantees. An extensive experimental evaluation shows that our method can improve ranking fairness substantially with no or only little loss of model quality.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2102.05996"}],"oa":1,"citation":{"ama":"Konstantinov NH, Lampert C.
