Capturing the available information with chain maps on Delaunay complexes, we use persistent homology to quantify the evidence of recurrent behavior. We establish a sampling theorem to recover the eigenspaces of the endomorphism on homology induced by the self-map. Using a combinatorial gradient flow arising from the discrete Morse theory for Čech and Delaunay complexes, we construct a chain map to transform the problem from the natural but expensive Čech complexes to the computationally efficient Delaunay triangulations.

After long-term extensive cultivation at 15°C it turned out to be a tied binary culture of archaeal (JL01) and bacterial (Sphaerochaeta associata GLS2) strains.\r\nStrain JL01 was a strict anaerobe and grew on methanol, acetate and methylamines as energy and carbon sources. Cells were irregular coccoid, non-motile, non-spore-forming, and Gram-stainpositive. Optimum conditions for growth were 24-28 oC, pH 6.8–7.3 and 0.075-0.1 M NaCl.\r\nPhylogenetic tree reconstructions based on 16S rRNA and concatenated alignment of broadly\r\nconserved protein-coding genes revealed its close relation to Methanosarcina mazei S-6\r\nT (similarity 99.5%). The comparison of whole genomic sequences (ANI) of the isolate and the type strain of M.mazei was 98.5%, which is higher than the values recommended for new species. Thus strain JL01 (=VKM B-2370=JCM 31898) represents the first M. mazei isolated from permanently subzero Arcticsediments. The long-term co-cultivation of JL01 with S. associata GLS2T showed the methane production without any additional carbon and energy sources.

In the same step, the chosen node picks a random neighbor, and the two nodes balance their loads by averaging them. We are interested in the expected gap between the minimum and maximum loads at nodes as the process progresses, and its dependence on n and on the graph structure. Variants of the above graphical balanced allocation process have been studied previously by Peres, Talwar, and Wieder [Peres et al., 2015], and by Sauerwald and Sun [Sauerwald and Sun, 2015]. These authors left as open the question of characterizing the gap in the case of cycle graphs in the dynamic case, where weights are created during the algorithm’s execution. For this case, the only known upper bound is of 𝒪(n log n), following from a majorization argument due to [Peres et al., 2015], which analyzes a related graphical allocation process. In this paper, we provide an upper bound of 𝒪 (√n log n) on the expected gap of the above process for cycles of length n. We introduce a new potential analysis technique, which enables us to bound the difference in load between k-hop neighbors on the cycle, for any k ≤ n/2. We complement this with a \"gap covering\" argument, which bounds the maximum value of the gap by bounding its value across all possible subsets of a certain structure, and recursively bounding the gaps within each subset. We provide analytical and experimental evidence that our upper bound on the gap is tight up to a logarithmic factor."}],"oa_version":"Published Version","arxiv":1},{"department":[{"_id":"LaEr"}],"status":"public","title":"Random matrices","doi":"10.4171/owr/2019/56","citation":{"short":"L.

For example, the cumulative effects of independent or weakly dependent random variables often yield the Gaussian universality class via the central limit theorem. For non-commutative random variables, e.g. matrices, the Gaussian behavior is often replaced by another universality class, commonly called random matrix statistics. Nearby eigenvalues are strongly correlated, and, remarkably, their correlation structure is universal, depending only on the symmetry type of the matrix. Even more surprisingly, this feature is not restricted to matrices; in fact Eugene Wigner, the pioneer of the field, discovered in the 1950s that distributions of the gaps between energy levels of complicated quantum systems universally follow the same random matrix statistics. This claim has never been rigorously proved for any realistic physical system but experimental data and extensive numerics leave no doubt as to its correctness. Since then random matrices have proved to be extremely useful phenomenological models in a wide range of applications beyond quantum physics that include number theory, statistics, neuroscience, population dynamics, wireless communication and mathematical finance. The ubiquity of random matrices in natural sciences is still a mystery, but recent years have witnessed a breakthrough in the mathematical description of the statistical structure of their spectrum. Random matrices and closely related areas such as log-gases have become an extremely active research area in probability theory.\r\nThis workshop brought together outstanding researchers from a variety of mathematical backgrounds whose areas of research are linked to random matrices. While there are strong links between their motivations, the techniques used by these researchers span a large swath of mathematics, ranging from purely algebraic techniques to stochastic analysis, classical probability theory, operator algebra, supersymmetry, orthogonal polynomials, etc.","lang":"eng"}],"oa_version":"None","issue":"4","date_created":"2024-03-05T07:54:44Z"},{"oa_version":"Published Version","date_created":"2024-03-05T08:57:17Z","main_file_link":[{"open_access":"1","url":"https://www1.pub.informatik.uni-wuerzburg.de/eurocg2020/data/uploads/papers/eurocg20_paper_56.pdf"}],"publication_status":"published","year":"2020","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"04","day":"01","corr_author":"1","quality_controlled":"1","acknowledgement":"Research on this work was initiated at the 6th Austrian-Japanese-Mexican-Spanish Workshop on Discrete Geometry and continued during the 16th European Geometric Graph-Week, both held near Strobl, Austria.

To study how TFs bind nucleosome-occupied motifs, we focused on the reprogramming factors OCT4 and SOX2 in mouse embryonic stem cells. We determined TF engagement throughout a nucleosome at base-pair resolution in vitro, enabling structure determination by cryo–electron microscopy at two preferred positions. Depending on motif location, OCT4 and SOX2 differentially distort nucleosomal DNA. At one position, OCT4-SOX2 removes DNA from histone H2A and histone H3; however, at an inverted motif, the TFs only induce local DNA distortions. OCT4 uses one of its two DNA-binding domains to engage DNA in both structures, reading out a partial motif. These findings explain site-specific nucleosome engagement by the pluripotency factors OCT4 and SOX2, and they reveal how TFs distort nucleosomes to access chromatinized motifs."}],"quality_controlled":"1","day":"23","publication_identifier":{"issn":["0036-8075"],"eissn":["1095-9203"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2020","month":"04","publication_status":"published","intvolume":"       368","author":[{"orcid":"0000-0002-6080-839X","last_name":"Michael","id":"6437c950-2a03-11ee-914d-d6476dd7b75c","first_name":"Alicia Kathleen","full_name":"Michael, Alicia Kathleen"},{"last_name":"Grand","first_name":"Ralph S.","full_name":"Grand, Ralph S."},{"last_name":"Isbel","first_name":"Luke","full_name":"Isbel, Luke"},{"full_name":"Cavadini, Simone","first_name":"Simone","last_name":"Cavadini"},{"last_name":"Kozicka","full_name":"Kozicka, Zuzanna","first_name":"Zuzanna"},{"last_name":"Kempf","full_name":"Kempf, Georg","first_name":"Georg"},{"last_name":"Bunker","full_name":"Bunker, Richard D.","first_name":"Richard D."},{"last_name":"Schenk","full_name":"Schenk, Andreas D.","first_name":"Andreas D."},{"full_name":"Graff-Meyer, Alexandra","first_name":"Alexandra","last_name":"Graff-Meyer"},{"last_name":"Pathare","first_name":"Ganesh R.","full_name":"Pathare, Ganesh R."},{"full_name":"Weiss, Joscha","first_name":"Joscha","last_name":"Weiss"},{"full_name":"Matsumoto, Syota","first_name":"Syota","last_name":"Matsumoto"},{"full_name":"Burger, Lukas","first_name":"Lukas","last_name":"Burger"},{"first_name":"Dirk","full_name":"Schübeler, Dirk","last_name":"Schübeler"},{"first_name":"Nicolas H.","full_name":"Thomä, Nicolas H.","last_name":"Thomä"}],"page":"1460-1465","date_published":"2020-04-23T00:00:00Z","article_processing_charge":"No","language":[{"iso":"eng"}],"publisher":"American Association for the Advancement of Science ","article_type":"original","date_updated":"2024-03-25T12:29:34Z","volume":368,"citation":{"short":"A.K.

Here we pinpoint a key difference between CRY1 and CRY2 that underlies their differential strengths as transcriptional repressors. Both cryptochromes bind the BMAL1 transactivation domain similarly to sequester it from coactivators and repress CLOCK:BMAL1 activity. However, we find that CRY1 is recruited with much higher affinity to the PAS domain core of CLOCK:BMAL1, allowing it to serve as a stronger repressor that lengthens circadian period. We discovered a dynamic serine-rich loop adjacent to the secondary pocket in the photolyase homology region (PHR) domain that regulates differential binding of cryptochromes to the PAS domain core of CLOCK:BMAL1. Notably, binding of the co-repressor PER2 remodels the serine loop of CRY2, making it more CRY1-like and enhancing its affinity for CLOCK:BMAL1.","lang":"eng"}],"type":"journal_article","publication_status":"published","keyword":["General Immunology and Microbiology","General Biochemistry","Genetics and Molecular Biology","General Medicine","General Neuroscience"],"year":"2020","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"02","intvolume":"         9","oa":1,"volume":9,"date_updated":"2024-03-25T12:25:02Z","article_type":"original","publication":"eLife","citation":{"apa":"Fribourgh, J.

With many missions currently under development and scheduled to launch as early as 2021, observations of the X-ray polarization of accreting X-ray pulsars will soon be available. As polarization is particularly sensitive to the geometry of the emission region, the upcoming polarimeters will shed new light on the emission mechanism of these objects, provided that we have sound theoretical models that agree with current spectroscopic and timing observation and that can make predictions of the polarization parameters of the emission. We here present a new model for the polarized emission of accreting X-ray pulsars in the accretion column scenario that for the first time takes into account the macroscopic structure and dynamics of the accretion region and the propagation of the radiation towards the observer, including relativistic beaming, gravitational lensing, and quantum electrodynamics.

We find that our model can describe the observed pulse fraction and the pulse shape of the main peak, as well as the modulation of the cyclotron line with phase. We pick two geometries, assuming a single accretion column or two columns at the magnetic poles, that can describe current observations of pulse shape and cyclotron modulation with phase. Both models predict a high polarization fraction, between 60 and 80 per cent in the 1–10 keV range, that is phase and energy dependent, and that peaks at the same phase as the intensity.

About one-fifth of white dwarfs exhibit the presence of magnetic fields, whose origin has long been debated as either the product of previous stages of evolution or of binary interactions. We here report the discovery of two massive and magnetic white-dwarf members of young star clusters in the Gaia second data release (DR2) database, while a third massive and magnetic cluster white dwarf was already reported in a previous paper. These stars are most likely the product of single-star evolution and therefore challenge the merger scenario as the only way to produce magnetic white dwarfs. The progenitor masses of these stars are all above 5 solar masses, and there are only two other cluster white dwarfs whose distances have been unambiguously measured with Gaia and whose progenitors' masses fall in this range. This high incidence of magnetic white dwarfs indicates that intermediate-mass progenitors are more likely to produce magnetic remnants and that a fraction of magnetic white dwarfs forms from intermediate-mass stars.","lang":"eng"}],"type":"journal_article","publication_status":"published","keyword":["Space and Planetary Science","Astronomy and Astrophysics"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2020","month":"09","intvolume":"       901","oa":1,"volume":901,"date_updated":"2024-10-14T12:33:09Z","article_type":"original","publication":"The Astrophysical Journal Letters","doi":"10.3847/2041-8213/abb5f7","citation":{"ama":"Caiazzo I, Heyl J, Richer H, et al.

This implementation, the Pioneer Soft X-ray Polarimeter (PiSoX) is a SmallSat, designed for NASA’s call for Astrophysics Pioneers, small missions that could be CubeSats, balloon experiments, or SmallSats. As in REDSoX, the grating arrangement is designed optimally for the purpose of polarimetry with broad-band focussing optics by matching the dispersion of the spectrometer channels to laterally graded multilayers (LGMLs). The system can achieve polarization modulation factors over 90%. For PiSoX, the optics are lightweight Si mirrors in a one-bounce parabolic configuration. High efficiency, blazed gratings from opposite sectors are oriented to disperse to a LGML forming a channel covering the wavelength range from 35 Å to 75 Å (165 - 350 eV). Upon satellite rotation, the intensities of the dispersed spectra, after reflection and polarizing by the LGMLs, give the three Stokes parameters needed to determine a source’s linear polarization fraction and orientation. The design can be extended to higher energies as LGMLs are developed further. We describe examples of the potential scientific return from instruments based on this design."}],"quality_controlled":"1","day":"13","month":"12","year":"2020","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","author":[{"full_name":"Marshall, Herman L.","first_name":"Herman L.","last_name":"Marshall"},{"last_name":"Heine","first_name":"Sarah","full_name":"Heine, Sarah"},{"last_name":"Garner","full_name":"Garner, Alan","first_name":"Alan"},{"last_name":"Gullikson","first_name":"Eric","full_name":"Gullikson, Eric"},{"first_name":"Moritz","full_name":"Guenther, Moritz","last_name":"Guenther"},{"last_name":"Leitz","full_name":"Leitz, Christopher","first_name":"Christopher"},{"last_name":"Masterson","first_name":"Rebecca","full_name":"Masterson, Rebecca"},{"last_name":"Miller","full_name":"Miller, Eric","first_name":"Eric"},{"first_name":"William","full_name":"Zhang, William","last_name":"Zhang"},{"last_name":"Boissay Malaquin","first_name":"Rozenn","full_name":"Boissay Malaquin, Rozenn"},{"last_name":"Caiazzo","orcid":"0000-0002-4770-5388","id":"8ae5b6e7-2a03-11ee-914d-b58ed7a3b47d","first_name":"Ilaria","full_name":"Caiazzo, Ilaria"},{"last_name":"Chakrabarty","full_name":"Chakrabarty, Deepto","first_name":"Deepto"},{"full_name":"Davidson, Rosemary","first_name":"Rosemary","last_name":"Davidson"},{"full_name":"Gallo, Luigi","first_name":"Luigi","last_name":"Gallo"},{"first_name":"Ralf K.","full_name":"Heilmann, Ralf K.","last_name":"Heilmann"},{"full_name":"Heyl, Jeremy","first_name":"Jeremy","last_name":"Heyl"},{"full_name":"Kara, Erin","first_name":"Erin","last_name":"Kara"},{"last_name":"Marscher","full_name":"Marscher, Alan","first_name":"Alan"},{"first_name":"Norbert","full_name":"Schulz, Norbert","last_name":"Schulz"}],"conference":{"name":"Astronomical Telescopes + Instrumentation","start_date":"2020-12-14","end_date":"2020-12-18","location":"Virtual"},"date_published":"2020-12-13T00:00:00Z","language":[{"iso":"eng"}],"article_processing_charge":"No","publisher":"SPIE","_id":"15228","article_number":"114442Y","scopus_import":"1","date_created":"2024-03-26T10:36:20Z","extern":"1","publication_identifier":{"eissn":["1996-756X"],"isbn":["978-151063675-0"]},"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2012.02829","open_access":"1"}]},{"oa_version":"None","extern":"1","date_created":"2024-03-26T10:36:40Z","publication_status":"published","year":"2020","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"12","day":"13","publication_identifier":{"eissn":["1996-756X"],"isbn":["978-151063675-0"]},"quality_controlled":"1","abstract":[{"lang":"eng","text":"We propose a high-time-resolution, high-spectral-resolution X-ray telescope that uses transition-edge sensors (TES) as detectors and collector optics to direct the X-rays onto the focal plane, providing a large effective area in a small satellite.

As a result, using our ADKG we remove the trusted setup assumption that the most scalable consensus algorithms make. In order to create a DKG with a dual (f,2f+1)- threshold we first answer in the affirmative the open question posed by Cachin et al. [7] on how to create an Asynchronous Verifiable Secret Sharing (AVSS) protocol with a reconstruction threshold of f+1<k łe 2f+1, which is of independent interest. Our High-threshold-AVSS (HAVSS) uses an asymmetric bivariate polynomial to encode the secret. This enables the reconstruction of the secret only if a set of k nodes contribute while allowing an honest node that did not participate in the sharing phase to recover his share with the help of f+1 honest parties. Once we have HAVSS we can use it to bootstrap scalable partially synchronous consensus protocols, but the question on how to get a DKG in asynchrony remains as we need a way to produce common randomness. The solution comes from a novel Eventually Perfect Common Coin (EPCC) abstraction that enables the generation of a common coin from n concurrent HAVSS invocations. EPCC's key property is that it is eventually reliable, as it might fail to agree at most f times (even if invoked a polynomial number of times). Using EPCC we implement an Eventually Efficient Asynchronous Binary Agreement (EEABA) which is optimal when the EPCC agrees and protects safety when EPCC fails. Finally, using EEABA we construct the first ADKG which has the same overhead and expected runtime as the best partially-synchronous DKG (O(n4) words, O(f) rounds). As a corollary of our ADKG, we can also create the first Validated Asynchronous Byzantine Agreement (VABA) that does not need a trusted dealer to setup threshold signatures of degree n-f. Our VABA has an overhead of expected O(n2) words and O(1) time per instance, after an initial O(n4) words and O(f) time bootstrap via ADKG."}],"quality_controlled":"1","day":"30","date_updated":"2025-07-10T11:49:52Z","oa":1,"status":"public","external_id":{"isi":["000768470400104"]},"title":"Asynchronous distributed key generation for computationally-secure randomness, consensus, and threshold signatures","department":[{"_id":"ElKo"}],"citation":{"ama":"Kokoris Kogias E, Malkhi D, Spiegelman A.
