In this paper, we give the first deterministic algorithm which runs in near-linear time for weighted graphs.\r\nPreviously, the breakthrough results of Kawarabayashi and Thorup [KT19] gave a near-linear time algorithm for simple graphs (which was improved to have running time O(m log2 n log log n) in [HRW20].) The main technique here is a clustering procedure that perfectly preserves minimum cuts. Recently, Li [Li21] gave an m1+o(1) deterministic minimum-cut algorithm for weighted graphs; this form of running time has been termed “almost-linear”. Li uses almost-linear time deterministic expander decompositions which do not perfectly preserve minimum cuts, but he can use these clusterings to, in a sense, “derandomize” the methods of Karger.\r\nIn terms of techniques, we provide a structural theorem that says there exists a sparse clustering that preserves minimum cuts in a weighted graph with o(1) error. In addition, we construct it deterministically in near linear time. This was done exactly for simple graphs in [KT19, HRW20] and with polylogarithmic error for weighted graphs in [Li21]. Extending the techniques in [KT19, HRW20] to weighted graphs presents significant challenges, and moreover, the algorithm can only polylogarithmically approximately preserve minimum cuts. A remaining challenge is to reduce the polylogarithmic-approximate clusterings to 1 + o(1/ log n)-approximate so that they can be applied recursively as in [Li21] over O(log n) many levels. This is an additional challenge that requires building on properties of tree-packings in the presence of a wide range of edge weights to, for example, find sources for local flow computations which identify minimum cuts that cross clusters."}],"title":"Deterministic near-linear time minimum cut in weighted graphs","day":"04","author":[{"full_name":"Henzinger, Monika H","first_name":"Monika H","last_name":"Henzinger","id":"540c9bbd-f2de-11ec-812d-d04a5be85630","orcid":"0000-0002-5008-6530"},{"full_name":"Li, Jason","first_name":"Jason","last_name":"Li"},{"last_name":"Rao","full_name":"Rao, Satish","first_name":"Satish"},{"last_name":"Wang","full_name":"Wang, Di","first_name":"Di"}],"OA_place":"repository","oa":1,"article_processing_charge":"No","OA_type":"free access","year":"2024","language":[{"iso":"eng"}],"external_id":{"arxiv":["2401.05627"]},"publication_identifier":{"eisbn":["9781611977912"]},"publication":"35th Annual ACM-SIAM Symposium on Discrete Algorithms"},{"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","citation":{"ista":"Surendranadh P. 2024.

In this regard, a key question is how genetically\r\ndistinct populations evolve in the face of gene flow, thereby generating genetic and\r\nphenotypic divergence and reproductive isolation (RI). This requires quantifying the role\r\nand relative contributions of prezygotic and postzygotic isolating mechanisms on the\r\nreduction of gene exchange between populations, and identifying regions in the genome\r\nthat mediate RI, which is often polygenic. Further, this needs distinguishing neutral and\r\nselected regions in the genome, and discerning how selection influences patterns of neutral\r\ndivergence.\r\nPopulation structure, defined as any deviation from panmixia, such as geographic distribution, movement and mating patterns of individuals, influences how genetic variation is\r\nstructured in space and shapes the neutral null model. Availability of large scale spatial\r\ngenomic datasets now enables us to detect signatures of population structure in genetic\r\ndata and infer population genetic parameters. Such inferences are crucial and have wide\r\napplications in biodiversity, conservation genetics, population management and medical\r\ngenetics. However, inferences are based on assumptions that do not always match the\r\ncomplex reality, thus leading to erroneous conclusions. Moreover, the role and interaction\r\nof heterogeneous population density and dispersal, which are ubiquitous in nature, has\r\nbeen challenging to study owing to their mathematical complexity. In such scenarios,\r\nfeedback between theory, data and simulations can prove to be useful.\r\nIn this thesis, I examine the effect of population structure on neutral genetic variation\r\nand barriers to gene exchange in hybridising populations, thereby bridging together the\r\nfields of spatial population genetics and speciation.\r\nDespite being a key concept in speciation, reproductive isolation (RI) lacks a quantitative\r\ndefinition and has been used and measured differently across different fields. Chapter 2\r\ngives a quantitative definition of RI, in terms of the effect of genetic differences on gene\r\nflow. We give analytical predictions for RI in a range of scenarios, in terms of effective migration rates for discrete populations and barrier strength for continuous populations.\r\nIn addition to this, we discuss current measures of RI and their limitations, and propose\r\nthe need for new measures that combine organismal and genetic perspectives of RI.\r\nIn chapter 3, I examine the combined effect of assortative mating, sexual selection\r\nand viability selection on RI. For this, we consider a polygenic ‘magic’ trait under a\r\nmainland-island model. We obtain novel theoretical predictions for molecular divergence\r\nin terms of effective migration rates, which bears a simple relationship to measurable\r\nfitness components of migrants and various early generation hybrids. We explore the\r\nconditions under which local adaptation can be maintained despite maladaptive gene flow\r\nand quantify the relative contributions of viability and sexual selection to genome-wide\r\nbarriers to gene flow.\r\nThe next two chapters of the thesis focus on a hybrid zone of Antirrhinum majus that\r\nconsist of two subspecies- the magenta flowered A. m. pseudomajus and the yellow\r\nflowered A.m. striatum. Previous studies have suggested that flower colour is target of\r\npollinator mediated selection and is influenced only by few genes. While these regions\r\nshow high genetic differentiation between the subspecies, the rest of the genome is seen\r\nto be well mixed. Chapter 4 examines the effects of heterogeneous population density\r\nand leptokurtic dispersal on isolation by distance and the distribution of heterozygosity\r\nby focusing on non-flower colour markers.\r\nChapter 5 analyses cline shapes and associations among 6 focal flower colour markers to\r\nunderstand how selection and dispersal maintain this hybrid zone. We see sharp coincident\r\nstepped clines at all loci and positive associations throughout the hybrid zone, contrary to\r\nthe expected patterns from diffusive gene flow. With a novel scheme of inferring dispersal\r\ncombined with multilocus simulations, we show that stepped clines do not reflect genetic\r\nbarriers to gene flow, but are rather a result of long-distance migration. This framework\r\nallows us to get realistic estimates gene flow and selection and shows how traditional cline\r\nanalysis may lead to inaccurate conclusions when assumptions of the theory are not met.\r\nOverall, this thesis investigates how different features of population structure leave\r\ndetectable signatures in genetic variation, namely in patterns of isolation by distance,\r\nlinkage disequilibrium and genetic divergence. It also highlights how effective migration\r\nrates provide useful way of analysing polygenic architectures and shed new light into\r\nhybrid zones. In doing so, I identify scenarios when simple models become insufficient\r\nand suggest possibe directions by combining genetic data with simulations.","lang":"eng"}],"acknowledgement":"I also acknowledge the funding agencies Marie Curie COFUND Doctoral Fellowship,\r\nAustrian Science Fund FWF (grant P32166) and ERC (grant PR1000ERC02) for financially\r\nsupporting my research over the years.","page":"219","publication_status":"published","article_processing_charge":"No","OA_type":"gold","oa":1,"OA_place":"publisher","degree_awarded":"PhD","ddc":["576"],"day":"07","author":[{"first_name":"Parvathy","full_name":"Surendranadh, Parvathy","orcid":"0000-0001-6395-386X","last_name":"Surendranadh","id":"455235B8-F248-11E8-B48F-1D18A9856A87"}],"supervisor":[{"first_name":"Nicholas H","full_name":"Barton, Nicholas H","orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","last_name":"Barton"}]},{"file_date_updated":"2024-11-11T09:42:28Z","license":"https://creativecommons.org/licenses/by/4.0/","department":[{"_id":"ToHe"},{"_id":"GradSch"}],"publisher":"Springer Nature","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":"     15191","date_published":"2024-10-12T00:00:00Z","citation":{"ama":"Bonakdarpour B, Momtaz A, Nickovic D, Sarac NE.

The autocorrelation function of faint z ≈ 6 quasars was also recently estimated. These measurements provide key insights into the properties of quasars and galaxies at high redshift and their relation with the host dark matter haloes. In this work, we interpret these data building upon an empirical quasar population model that has been applied successfully to quasar clustering and demographic measurements at z ≈ 2–4. We use a new, large-volume N-body simulation with more than a trillion particles, FLAMINGO-10k, to model quasars and galaxies simultaneously. We successfully reproduce observations of z ≈ 6 quasars and galaxies (i.e. their clustering properties and luminosity functions), and infer key quantities such as their luminosity–halo mass relation, the mass function of their host haloes, and their duty cycle/occupation fraction. Our key findings\r\nare (i) quasars reside on average in ≈ 1012.5 M haloes (corresponding to ≈ 5σ fluctuations in the initial conditions of the linear density field), but the distribution of host halo masses is quite broad; (ii) the duty cycle of (UV-bright) quasar activity is relatively low (≈ 1 per cent); (iii) galaxies (that are bright in [O III]) live in much smaller haloes (≈ 1010.9 M) and have a larger duty cycle (occupation fraction) of ≈ 13 per cent. Finally, we focus on the inferred properties of quasars and present a homogeneous analysis of their evolution with redshift. The picture that emerges reveals a strong evolution of the host halo mass and duty cycle of quasars at z ≈ 2–6, and calls for new investigations of the role of quasar activity across cosmic time."}],"publisher":"Oxford University Press","file_date_updated":"2024-11-12T07:17:26Z","department":[{"_id":"JoMa"}],"status":"public","intvolume":"       534","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","DOAJ_listed":"1","citation":{"apa":"Pizzati, E., Hennawi, J.

Binary evolution theory predicts that the Hertzsprung gap is home to multiple populations of binary systems with varied evolutionary histories. In this paper, we develop a method to distinguish single YSGs from YSG plus O- or B-type main-sequence binaries using optical and ultraviolet photometry, and then apply this method to identify candidate YSG binaries in the Magellanic Clouds. After constructing a set of combined stellar atmosphere models, we find that optical photometry is, given typical measurement and reddening uncertainties, sufficient to discern single YSGs from YSG+OB binaries if the OB-star is at least ∼5M⊙ for Teff,YSG ∼ 4000 K, but requires a ∼20M⊙ OB star for YSGs up to Teff,YSG ∼ 9000 K. For these hotter YSG temperatures, ultraviolet photometry allows binaries with OB companions as small as ∼7M⊙ to be identified. We use color–color spaces developed from these models to search for evidence of excess blue or ultraviolet light in a set of ∼1000 YSG candidates in the Magellanic Clouds. We identify hundreds of candidate YSG binary systems and report a preliminary fraction of YSGs that show a blue/UV color excess of 20%–60%. Spectroscopic follow-up is now required to confirm the true nature of this population.","lang":"eng"}],"title":"Binary yellow supergiants in the Magellanic Clouds. I.

These loci are scattered throughout the genome and are individually responsible only for small fractions of the total heritable trait variance. The recently proposed omnigenic model provides a conceptual framework to explain these observations by postulating that numerous distant loci contribute to each complex trait via effect propagation through intracellular regulatory networks. We formalize this conceptual framework by proposing the “quantitative omnigenic model” (QOM), a statistical model that combines prior knowledge of the regulatory network topology with genomic data. By applying our model to gene expression traits in yeast, we demonstrate that QOM achieves similar gene expression prediction performance to traditional GWAS with hundreds of times less parameters, while simultaneously extracting candidate causal and quantitative chains of effect propagation through the regulatory network for every individual gene. We estimate the fraction of heritable trait variance in cis- and in trans-, break the latter down by effect propagation order, assess the trans- variance not attributable to transcriptional regulation, and show that QOM correctly accounts for the low-dimensional structure of gene expression covariance. We furthermore demonstrate the relevance of QOM for systems biology, by employing it as a statistical test for the quality of regulatory network reconstructions, and linking it to the propagation of nontranscriptional (including environmental) effects."}],"publisher":"National Academy of Sciences","file_date_updated":"2024-11-11T09:31:00Z","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","department":[{"_id":"GaTk"},{"_id":"NiBa"}],"article_number":"e2402340121","corr_author":"1","status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","intvolume":"       121","citation":{"ieee":"N.

In Arabidopsis, endosomal membrane constriction and scission are uncoupled, resulting in the formation of extensive concatenated ILV networks and enhancing cargo sequestration efficiency. Here, we used a combination of electron tomography, computer simulations, and mathematical modeling to address the questions of when concatenated ILV networks evolved in plants and what drives their formation. Through morphometric analyses of tomographic reconstructions of endosomes across yeast, algae, and various land plants, we have found that ILV concatenation is widespread within plant species, but only prevalent in seed plants, especially in flowering plants. Multiple budding sites that require the formation of pores in the limiting membrane were only identified in hornworts and seed plants, suggesting that this mechanism has evolved independently in both plant lineages. To identify the conditions under which these multiple budding sites can arise, we used particle-based molecular dynamics simulations and found that changes in ESCRT filament properties, such as filament curvature and membrane binding energy, can generate the membrane shapes observed in multiple budding sites. To understand the relationship between membrane budding activity and ILV network topology, we performed computational simulations and identified a set of membrane remodeling parameters that can recapitulate our tomographic datasets."}],"title":"Endosomal membrane budding patterns in plants","issue":"44","author":[{"last_name":"Weiner","full_name":"Weiner, Ethan","first_name":"Ethan"},{"last_name":"Berryman","first_name":"Elizabeth","full_name":"Berryman, Elizabeth"},{"orcid":"0000-0001-8501-6017","last_name":"Frey","id":"a0270b37-8f1a-11ec-95c7-8e710c59a4f3","first_name":"Felix F","full_name":"Frey, Felix F"},{"last_name":"Solís","first_name":"Ariadna González","full_name":"Solís, Ariadna González"},{"last_name":"Leier","full_name":"Leier, André","first_name":"André"},{"full_name":"Lago, Tatiana Marquez","first_name":"Tatiana Marquez","last_name":"Lago"},{"first_name":"Anđela","full_name":"Šarić, Anđela","id":"bf63d406-f056-11eb-b41d-f263a6566d8b","last_name":"Šarić","orcid":"0000-0002-7854-2139"},{"last_name":"Otegui","first_name":"Marisa S.","full_name":"Otegui, Marisa S."}],"day":"29","ddc":["570"],"oa":1,"OA_place":"publisher","OA_type":"hybrid","article_processing_charge":"Yes (in subscription journal)"},{"date_updated":"2025-09-08T14:42:50Z","volume":84,"date_created":"2024-11-15T12:12:54Z","quality_controlled":"1","_id":"18553","oa_version":"Published Version","month":"12","scopus_import":"1","doi":"10.1016/j.molcel.2024.10.030","has_accepted_license":"1","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"type":"journal_article","date_published":"2024-12-19T00:00:00Z","citation":{"mla":"Ramadhin, Anisha R., et al. “STK19 Drives Transcription-Coupled Repair by Stimulating Repair Complex Stability, RNA Pol II Ubiquitylation, and TFIIH Recruitment.” <i>Molecular Cell</i>, vol. 84, no. 24, Elsevier, 2024, p. 4740–4757.e12, doi:<a href=\"https://doi.org/10.1016/j.molcel.2024.10.030\">10.1016/j.molcel.2024.10.030</a>.","short":"A.R.

TC-NER is initiated by the recognition of lesion-stalled RNA Pol II by CSB, which recruits the CRL4CSA ubiquitin ligase and UVSSA. RNA Pol II ubiquitylation at RPB1-K1268 by CRL4CSA serves as a critical TC-NER checkpoint, governing RNA Pol II stability and initiating DNA damage excision by TFIIH recruitment. However, the precise regulatory mechanisms of CRL4CSA activity and TFIIH recruitment remain elusive. Here, we reveal human serine/threonine-protein kinase 19 (STK19) as a TC-NER factor, which is essential for correct DNA damage removal and subsequent transcription restart. Cryogenic electron microscopy (cryo-EM) studies demonstrate that STK19 is an integral part of the RNA Pol II-TC-NER complex, bridging CSA, UVSSA, RNA Pol II, and downstream DNA. STK19 stimulates TC-NER complex stability and CRL4CSA activity, resulting in efficient RNA Pol II ubiquitylation and correct UVSSA and TFIIH binding. These findings underscore the crucial role of STK19 as a core TC-NER component.","lang":"eng"}],"title":"STK19 drives transcription-coupled repair by stimulating repair complex stability, RNA Pol II ubiquitylation, and TFIIH recruitment","page":"4740-4757.e12","publication_status":"published","acknowledgement":"We thank N.

These behaviours require control mechanisms that can extract information from the environment, particularly visual cues. Selective evolutionary pressures have thus refined such visuomotor transformations in a species-specific manner to meet the specific ecological and ethological challenges of each organism. However, a common challenge across organisms as visual information processing\r\nbecomes increasingly detailed is the mechanisms required to synthesise disparate pieces of information into a coherent percept or unified picture of the world. In this thesis, I investigate how disparate visual information is combined in the brain of Drosophila melanogaster to effectively guide locomotion.\r\nFor this, I first designed and built a behavioural setup to record locomotion and present visual stimuli to freely-walking fruit flies in a closed-loop manner. This setup allowed the investigation of innate visually-guided behaviours, including the optomotor reflex and courtship.\r\nSecond, taking advantage of my system I investigated the optomotor response, a reflexive visual stabilisation behaviour in which flies turn in the direction of global motion to minimise retinal slip. This behaviour is thought to be mediated by Lobula plate tangential cells (LPTCs); a complex network of optic-flow-sensitive neurons essential for self-motion estimation. Using a novel genetic mutant, I demonstrate that electrical coupling between two LPTC subtypes, contralateral HS and H2 neurons, regulates the balance between smooth optomotor turning and saccadic anti-optomotor responses. These findings underscore the critical role of binocular motion cue integration in guiding course control. Finally, I developed a novel behavioural paradigm in which a sexually aroused male fruit fly is presented with an optomotor distractor. This setup creates competition between two visual behaviours, courtship tracking and the  optomotor response, enabling me to explore how the visual system resolves this conflict. In this setting, males\r\nengaged in courtship selectively suppress their optomotor response based on the female's location. Furthermore, when this experiment is replicated with an “artificial female”, optogenetically aroused males alternate between tracking and optomotor responses. The probability and dynamics of this switching are determined by the relative strengths of the two competing stimuli. In summary, the results presented in this thesis explore two mechanisms – integration and competition - through which visual information is combined in the brain of the fruit fly to drive locomotion.","lang":"eng"}],"title":"Mechanisms of visual integration and competition in innate behaviours in Drosophila melanogaster","supervisor":[{"orcid":"0000-0002-3937-1330","last_name":"Jösch","id":"2BD278E6-F248-11E8-B48F-1D18A9856A87","full_name":"Jösch, Maximilian A","first_name":"Maximilian A"}],"ddc":["573"],"day":"20","author":[{"first_name":"Roshan K","full_name":"Satapathy, Roshan K","id":"46046B7A-F248-11E8-B48F-1D18A9856A87","last_name":"Satapathy","orcid":"0009-0006-2974-5075"}],"oa":1,"OA_place":"publisher","degree_awarded":"PhD","article_processing_charge":"No"},{"department":[{"_id":"MaJö"}],"file_date_updated":"2024-12-09T12:54:55Z","publisher":"Institute of Science and Technology Austria","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2024-12-09T00:00:00Z","citation":{"short":"T.A.

The aim of our study was to investigate the potential of conditioned medium (CM) from hiPSC-mesenchymal progenitors (hiPSC-MPs) to stimulate osteogenic differentiation of human bone marrow-derived mesenchymal stromal cells (MSCs). We also investigated whether prolonged cultivation or osteogenic pre-differentiation of hiPSC-MPs could enhance the stimulatory activity of CM.\r\nMethods: MSCs were isolated from 13 donors (age 20–90 years). CM derived from hiPSC-MPs was added to the MSC cultures and the effects on proliferation and osteogenic differentiation were examined after 14 days and 6 weeks. The stimulatory activity of hiPSC-MP-CM was compared with the activity of MSC-derived CM and with the activity of CM prepared from hiPSC-MPs pre-cultured in growth or osteogenic medium for 14 days. Comparative proteomic analysis of CM was performed to gain insight into the molecular components responsible for the stimulatory activity.\r\nResults: Primary bone marrow-derived MSC exhibited variability, with a tendency towards lower proliferation and tri-lineage differentiation in older donors. hiPSC-MP-CM increased the proliferation and alkaline phosphatase activity of MSC from several adult/aged donors after 14 days of continuous supplementation under osteogenic conditions. However, CM supplementation failed to improve the mineralization of MSC pellets after 6 weeks under osteogenic conditions. hiPSC-MP-CM showed greater enhancement of proliferation and ALP activity than CM derived from bone marrow-derived MSCs. Moreover, 14-day cultivation but not osteogenic pre-differentiation of hiPSC-MPs strongly enhanced CM stimulatory activity. Quantitative proteomic analysis of d14-CM revealed a distinct profile of components that formed a highly interconnected associations network with two clusters, one functionally associated with binding and organization of actin/cytoskeletal components and the other with structural constituents of the extracellular matrix, collagen, and growth factor binding. Several hub proteins were identified that were reported to have functions in cell-extracellular matrix interaction, osteogenic differentiation and development.\r\nConclusions: Our data show that hiPSC-MP-CM enhances early osteogenic differentiation of human bone marrow-derived MSCs and that prolonged cultivation of hiPSC-MPs enhances CM-stimulatory activity. Proteomic analysis of the upregulated protein components provides the basis for further optimization of hiPSC-MP-CM for bone regenerative therapies."}],"author":[{"last_name":"Marolt Presen","first_name":"Darja","full_name":"Marolt Presen, Darja"},{"first_name":"Vanessa","full_name":"Goeschl, Vanessa","last_name":"Goeschl"},{"last_name":"Hanetseder","first_name":"Dominik","full_name":"Hanetseder, Dominik"},{"first_name":"Laura","full_name":"Ogrin, Laura","last_name":"Ogrin"},{"last_name":"Stetco","full_name":"Stetco, Alexandra Larissa","first_name":"Alexandra Larissa"},{"last_name":"Tansek","first_name":"Anja","full_name":"Tansek, Anja"},{"first_name":"Laura","full_name":"Pozenel, Laura","last_name":"Pozenel"},{"id":"70abbbb3-88ea-11ec-8e0a-e8c939944834","last_name":"Bruszel","full_name":"Bruszel, Bella","first_name":"Bella"},{"full_name":"Mitulovic, Goran","first_name":"Goran","last_name":"Mitulovic"},{"full_name":"Oesterreicher, Johannes","first_name":"Johannes","last_name":"Oesterreicher"},{"last_name":"Zipperle","full_name":"Zipperle, Johannes","first_name":"Johannes"},{"full_name":"Schaedl, Barbara","first_name":"Barbara","last_name":"Schaedl"},{"last_name":"Holnthoner","first_name":"Wolfgang","full_name":"Holnthoner, Wolfgang"},{"last_name":"Grillari","full_name":"Grillari, Johannes","first_name":"Johannes"},{"last_name":"Redl","full_name":"Redl, Heinz","first_name":"Heinz"}],"day":"01","ddc":["570"],"OA_type":"gold","article_processing_charge":"Yes","OA_place":"publisher","oa":1,"article_number":"434","status":"public","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","intvolume":"        15","DOAJ_listed":"1","date_published":"2024-12-01T00:00:00Z","citation":{"ama":"Marolt Presen D, Goeschl V, Hanetseder D, et al.

For example, the majority colouring conjecture of Kreutzer, Oum, Seymour, van der Zypen and Wood states that every directed graph has a 3-colouring such that for every vertex v, at most half of the out-neighbours of v have the same colour as \r\n. As another example, the internal partition conjecture, due to DeVos and to Ban and Linial, states that for every d, all but finitely many d-regular graphs have a partition into two non-empty parts such that for every vertex v, at least half of the neighbours of v lie in the same part as v. We prove several results in this spirit: in particular, two of our results are that the majority colouring conjecture holds for Erdős–Rényi random directed graphs (of any density), and that the internal partition conjecture holds if we permit a tiny number of ‘exceptional vertices’. Our proofs involve a variety of techniques, including several different methods to analyse random recolouring processes. One highlight is a personality-changing scheme: we ‘forget’ certain information based on the state of a Markov chain, giving us more independence to work with.","lang":"eng"}],"title":"Partitioning problems via random processes","publication_status":"published","acknowledgement":"We are grateful to the anonymous referees for their thorough reading of the paper, and for many suggestions which have improved the exposition throughout.\r\n\r\nMichael Anastos was supported by the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 101034413.

Executed in 2023 November, MegaScience obtained ∼30 arcmin2 of deep multiband NIRCam imaging centered on the z ∼ 0.3 A2744 cluster, including 11 medium-band filters and the two shortest-wavelength broadband filters, F070W and F090W. Together, MegaScience and the UNCOVER Cycle 1 treasury program provide a complete set of deep (∼28–30 magAB) images in all NIRCam medium- and broadband filters. This unique data set allows us to precisely constrain photometric redshifts, map stellar populations and dust attenuation for large samples of distant galaxies, and examine the connection between galaxy structures and formation histories. MegaScience also includes ∼17 arcmin2 of NIRISS parallel imaging in two broadband and four medium-band filters from 0.9 to 4.8 μm, expanding the footprint where robust spectral energy distribution (SED) fitting is possible. We provide example SEDs and multiband cutouts at a variety of redshifts, and use a catalog of JWST spectroscopic redshifts to show that MegaScience improves both the scatter and catastrophic outlier rate of photometric redshifts by factors of 2–3. Additionally, we demonstrate the spatially resolved science enabled by MegaScience by presenting maps of the [O iii] line emission and continuum emission in three spectroscopically confirmed z > 6 galaxies. We show that line emission in reionization-era galaxies can be clumpy, extended, and spatially offset from continuum emission, implying that galaxy assembly histories are complex even at these early epochs. We publicly release fully reduced mosaics and photometric catalogs for both the NIRCam primary and NIRISS parallel fields (jwst-uncover.github.io/megascience).","lang":"eng"}],"acknowledgement":"K.A.S. thanks Shelly Meyett, the MegaScience Program Coordinator, for invaluable assistance designing WOPR 88967 and ensuring that this program was fully observed.

Our unbiased spectroscopic search results in 137 spectroscopically-confirmed galaxies at 6.8<z<9.0 with observed [OIII] fluxes f[OIII]≳1×10−18 ergs s−1 cm−2. The rest-frame optical line ratios of the median stacked spectrum (median MUV=−19.65+0.59−1.05) indicate negligible dust attenuation, low metallicity (12+log(O/H)=7.2−7.7) and a high ionisation parameter log10U≃−2.5. We find a factor ×1.3 difference in the number density of 6.8<z<9.0 galaxies between GOODS-South and GOODS-North, which is caused by a single overdensity at 7.0<z<7.2 in GOODS-North. The bright end of the UV luminosity function of spectroscopically-confirmed [OIII] emitters is in good agreement with HST dropout-selected samples. Discrepancies between the observed [OIII] LF, [OIII]/UV ratio and [OIII] equivalent widths, and that predicted by theoretical models, suggest burstier star-formation histories and/or more heterogeneous metallicity and ionising conditions in z>7 galaxies. We report a rapid decline of the [OIII] luminosity density at z≳6−7 which cannot be explained by the evolution of the cosmic star-formation rate density. Finally we find that FRESCO detects in only 2h galaxies likely accounting for ∼10−20% of the ionising budget at z=7−8 (assuming an escape fraction of 10%), raising the prospect of directly detecting a significant fraction of the sources of reionisation with JWST."}]},{"scopus_import":"1","project":[{"_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","name":"IST-BRIDGE: International postdoctoral program","call_identifier":"H2020","grant_number":"101034413"}],"_id":"18586","month":"11","oa_version":"Preprint","date_updated":"2025-09-08T14:48:42Z","volume":21,"date_created":"2024-11-24T23:01:49Z","quality_controlled":"1","doi":"10.30757/ALEA.V21-70","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2404.11700"}],"type":"journal_article","intvolume":"        21","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_published":"2024-11-01T00:00:00Z","citation":{"ama":"CZUDEK KS, Dolgopyat D.
