It considers how continuous manifolds relate to their discrete analogues, how topological structures evolve in persistence vineyards, and how tools from topological data analysis can illuminate problems in mathematical physics. Central to this exploration is the question of how structure, both geometric and topological, persists or changes under approximation, sampling, or deformation. The work develops new approaches to skeletal and grid-based representations of surfaces, reveals the full expressive capacity of persistence vineyards, and applies topological methods to the longstanding problem of equilibria in electrostatic fields. These threads braid together into a broader understanding of how topology and geometry inform one another across theory, computation, and application.","lang":"eng"}],"department":[{"_id":"GradSch"},{"_id":"HeEd"},{"_id":"UlWa"}],"supervisor":[{"full_name":"Edelsbrunner, Herbert","last_name":"Edelsbrunner","orcid":"0000-0002-9823-6833","first_name":"Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Wagner","full_name":"Wagner, Uli","first_name":"Uli","id":"36690CA2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1494-0568"}],"oa":1,"corr_author":"1","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd"},{"publication":"npj Climate and Atmospheric Science","date_created":"2026-01-25T23:01:38Z","year":"2026","date_updated":"2026-02-12T08:41:09Z","publication_identifier":{"eissn":["2397-3722"]},"acknowledgement":"We thank Sophie Cloché for her support with the handling of the various datasets.

This decrease is manifested by a decrease of the mass transported in the upward branch of the atmospheric overturning circulation – the convective mass flux – and a connected decrease of high clouds in the tropics, with implications for climate sensitivity. By using kilometer-scale simulations in radiative-convective equilibrium and a convective tracking algorithm, we show that no such decrease occurs in storms when taken individually and that the mass transport per storm increases instead. Storms can achieve this result by aggregating more surface of the convective cores – the inner part of the storm doing the vertical transport – so that the decrease of tropical convection is actually explained by a decrease in the total number of storms. There is little variation of the mean pressure velocity in the cores of the storms, a robust finding of this study. This remarkable invariance of the mean pressure velocity points to an emerging property of convection that should receive more attention in future studies."}],"department":[{"_id":"CaMu"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"file_date_updated":"2026-02-12T08:39:27Z","language":[{"iso":"eng"}],"OA_type":"gold","pmid":1,"date_published":"2026-01-15T00:00:00Z","article_processing_charge":"Yes","title":"No decrease of tropical convection in individual deep convective systems with global warming","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"intvolume":" 9","has_accepted_license":"1","_id":"21035","type":"journal_article","publication_status":"published","file":[{"creator":"dernst","checksum":"c433bba3822b3c6c4a5260ad5e2429a0","success":1,"file_name":"2026_njpClimateAtmScience_Bolot.pdf","access_level":"open_access","relation":"main_file","file_size":511226,"content_type":"application/pdf","date_created":"2026-02-12T08:39:27Z","date_updated":"2026-02-12T08:39:27Z","file_id":"21215"}],"citation":{"chicago":"Bolot, Maximilien, Rémy Roca, Thomas Fiolleau, and Caroline J Muller. “No Decrease of Tropical Convection in Individual Deep Convective Systems with Global Warming.” Npj Climate and Atmospheric Science.

While the effects of grazing on individual forest attributes are well documented, their integrated consequences remain poorly understood, particularly in temperate forest ecosystems. We evaluated the combined influence of livestock grazing intensity and canopy cover on individual attributes and ecosystem multifunctionality in native Nothofagus forests of Tierra del Fuego, Argentina. Across eight ranches spanning two agroecological regions (Ecotone and Mountain Range), we quantified forest regeneration, understorey richness and biomass, and soil properties, integrating them into a multifunctionality index. Using generalized linear mixed models, we found strong context-dependence: in the Mountain Range, higher grazing intensity reduced seedling and sapling density, organic matter content, coarse woody debris, and overall multifunctionality. In the Ecotone, these effects of livestock use intensity were attenuated, and canopy cover diminished sapling density and multifunctionality, but moderate cover enhanced understorey. Our results extend multifunctionality research from grazed grasslands to grazed temperate forests and show that ecological responses and trade-offs vary across landscape units. We conclude that the Mountain Range is more vulnerable to grazing, requiring stricter management, whereas the Ecotone retains greater capacity to sustain multifunctionality under controlled livestock use intensity. These findings underscore the importance of region-specific silvopastoral strategies that reconcile food production with forest conservation in southern Patagonia and comparable temperate forest landscapes worldwide.","lang":"eng"}],"department":[{"_id":"NiBa"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"closed access","language":[{"iso":"eng"}],"title":"Context-dependent effects of livestock grazing on forest attributes and ecosystem multifunctionality in Nothofagus forests","article_processing_charge":"No","date_published":"2026-01-06T00:00:00Z","intvolume":" 400","type":"journal_article","_id":"21036"},{"oa_version":"Published Version","article_type":"original","month":"01","article_number":"123348","ddc":["540"],"status":"public","main_file_link":[{"url":"https://doi.org/10.1016/j.ces.2026.123348","open_access":"1"}],"OA_place":"publisher","quality_controlled":"1","doi":"10.1016/j.ces.2026.123348","day":"12","author":[{"last_name":"Shi","full_name":"Shi, Changwei","first_name":"Changwei"},{"id":"03a7e858-01b1-11ec-8b71-99ae6c4a05bc","first_name":"Sharona","last_name":"Horta","full_name":"Horta, Sharona"},{"orcid":"0000-0001-5013-2843","first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","last_name":"Ibáñez"},{"last_name":"Kallio","full_name":"Kallio, Tanja","first_name":"Tanja"},{"first_name":"Paulina R.","full_name":"Martínez-Alanis, Paulina R.","last_name":"Martínez-Alanis"},{"last_name":"Wang","full_name":"Wang, Xiang","first_name":"Xiang"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}],"volume":324,"publisher":"Elsevier","project":[{"_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A","name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery"}],"publication_status":"epub_ahead","citation":{"ieee":"C.

Here, we report a simple strategy for synthesizing a palladium-based heterostructured electrocatalyst supported on a carbon nitride matrix (PdH-Pd@CN), which exhibits remarkable ORR activity with a half-wave potential of 0.91 V and excellent durability in 0.1 M KOH. Within the heterostructure, hydrogen intercalation expands the Pd lattice, while interstitial hydrogen doping facilitates charge transfer from Pd to H owing to their electronegativity difference. These synergistic effects modulate the electronic structure, thereby enhancing both activity and stability. When employed in Zn-air batteries, PdH-Pd@CN delivers a maximum power density of 176 mW cm− (Liu et al., 2025) and capacity of 805 mAh g− (Sun et al., 2021) Zn. These findings demonstrate the strong potential of PdH-Pd@CN as an efficient ORR electrocatalyst for next-generation metal-air batteries and related energy technologies.","lang":"eng"}]},{"project":[{"name":"Young galaxies as tracers and agents of cosmic reionization","grant_number":"101076224","_id":"bd9b2118-d553-11ed-ba76-db24564edfea"}],"publisher":"Oxford University Press","volume":545,"author":[{"first_name":"Seok Jun","full_name":"Chang, Seok Jun","last_name":"Chang"},{"last_name":"Gronke","full_name":"Gronke, Max","first_name":"Max"},{"first_name":"Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J","last_name":"Matthee"},{"first_name":"Charlotte","last_name":"Mason","full_name":"Mason, Charlotte"}],"day":"01","scopus_import":"1","DOAJ_listed":"1","citation":{"short":"S.J.

Their spectra exhibit broad Balmer emission lines (>~1000 km s^−1), alongside absorption features and a pronounced Balmer break – evidence for a dense, neutral hydrogen medium, in which the n = 2 state is significantly populated. When interpreted as arising\r\nfrom active galactic nucleus broad-line regions, inferred black hole masses from local scaling relations exceed expectations given their stellar masses, challenging models of early black hole–galaxy co-evolution. However, radiative transfer effects in dense media may also impact the formation of hydrogen emission lines. We model three scattering processes shaping hydrogen\r\nline profiles: resonance scattering by hydrogen in the n = 2 state, Raman scattering of ultraviolet (UV) radiation by ground-state hydrogen, and Thomson scattering by free electrons. Using 3D Monte Carlo radiative transfer simulations, we examine their imprint on line shapes and ratios. Resonance scattering produces strong deviations from Case B flux ratios, clear differences\r\nbetween Hα and Hβ, and encodes gas kinematics in line profiles but cannot broaden Hβ due to conversion to Paα. While Raman scattering can yield broad wings, scattering of the UV continuum is disfavoured given the absence of strong full width at half-maximum variations across transitions. Raman scattering of higher Lyman-series emission can produce Hα/Hβ wing\r\nwidth ratios of >~1.28, agreeing with observations. Thomson scattering can reproduce the observed >~ 1000 km s^−1 wings under plausible conditions – e.g. Te ∼ 10^4 K and Ne ∼ 10^24 cm^−2 – and lead to black hole mass overestimates by factors 10.

Here, we report damage-induced cellular plasticity of secretory enteroendocrine cells (EEs) in the adult Drosophila midgut. Ionizing radiation induces EE fate conversion and activates stress-responsive programs in EE lineages, accompanied by the induction of the stress-inducible transcription factor Xrp1 and the cytokine gene upd3. Xrp1 and upd3 are both necessary for radiation-induced EE plasticity. Under basal conditions, EE-specific Xrp1 overexpression triggers ectopic expression of progenitor-specific genes, which is necessary for Xrp1 to drive EE plasticity.

However, the nature and effect of the changes are material-dependent and unknown for the important class of Co-free, Ni-poor LRLOs. Here, we analyze the processes during the tailored formation procedure of a typical class member, Li1.28Ni0.15Mn0.57O2, and demonstrate that it remarkably changes lattice composition and structure as a prerequisite for stable cycling. We combine electrochemistry, operando mass spectrometry, X-ray diffraction, and X-ray absorption spectroscopy with density functional theory simulations. Activation most prominently compresses the layer spacing along the c-axis and increases reversible structural breathing. The large capacity of ∼250 mAh g–1 originates from the Ni2+/Ni4+ and O2–/O– redox couples. Electron exchange during O-redox is smeared over the entire anionic sublattice rather than localized on specific oxygen atomic sites. This redox mechanism is reversible without detrimental oxygen evolution, avoiding continued degradation common in conventional LRLOs. Sequential Ni- and O-redox during activation irreversibly distorts the coordination of the redox-inactive Mn4+ centers. This structural evolution of the MnO6 octahedra appears to enable the superior electrochemical performance of this LRLO phase. These findings define an activation pathway for the important class of Co-free, Ni-poor LRLOs, offering potential guidance for the rational design of high-performance, more sustainable cathode materials."}],"date_updated":"2026-02-12T14:04:04Z","year":"2026","date_created":"2026-01-25T23:01:40Z","publication":"ACS Applied Energy Materials","acknowledgement":"Elettra-Sincrotrone Trieste S.C.p.A. and its staff are acknowledged for providing synchrotron radiation beamtime and laboratory facilities, in particular the MCX and XAFS beamlines, where the XRD and XAS experiments have been carried out, supported by the projects number: 20217082, 20205109, and 20195014.

In this context, a trusted program component is said to be robustly safe if it behaves safely when linked against arbitrary untrusted code. Prior work has shown how various encapsulation mechanisms (in both high- and low-level languages) can be used to protect code so that it is robustly safe, but none of the existing work has explored how robust safety can be achieved in a patently unsafe language like C.\r\nIn this paper, we show how to bring robust safety to a simple yet representative C-like language we call Rec. Although Rec (like C) is inherently ”dangerous” and thus not robustly safe, we can ”save” Rec programs via compilation to Cap, a CHERI-like capability machine. To formalize the benefits of such a hardening compiler, we develop Reckon, a separation logic for verifying robust safety of Rec programs. Reckon is not sound under Rec’s unsafe, C-like semantics, but it is sound when Rec programs are hardened via compilation and linked against untrusted code running on Cap. As a crucial step in proving soundness of Reckon, we introduce a novel technique of semantic back-translation, which we formalize by building on the DimSum framework for multi-language semantics.

A common approach to scale execution is parallel execution engines that fully utilize modern multi-core architectures. Parallel execution is then either done optimistically, by executing transactions in parallel and detecting conflicts on the fly, or guided, by requiring exhaustive client transaction hints and scheduling transactions accordingly.\r\n\r\nHowever, recent studies have shown that the performance of parallel execution engines depends on the nature of the underlying workload. In fact, in some cases, only a 60% speed-up compared to sequential execution could be obtained. This is the case, as transactions that access the same resources must be executed sequentially. For example, if 10% of the transactions in a block access the same resource, the execution cannot meaningfully scale beyond 10 cores. Therefore, a single popular application can bottleneck the execution and limit the potential throughput.\r\n\r\nIn this paper, we introduce Anthemius, a block construction algorithm that optimizes parallel transaction execution throughput. We evaluate Anthemius exhaustively under a range of workloads, and show that Anthemius enables the underlying parallel execution engine to process over twice as many transactions."}],"department":[{"_id":"KrPi"}],"corr_author":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"language":[{"iso":"eng"}],"OA_type":"green","date_published":"2026-01-01T00:00:00Z","title":"Anthemius: Efficient and modular block assembly for concurrent execution","article_processing_charge":"No","intvolume":" 15751","type":"conference","_id":"21042"},{"abstract":[{"lang":"eng","text":"Scalability is a crucial requirement for modern large-scale systems, enabling elasticity and ensuring responsiveness under varying load. While cloud systems have achieved scalable architectures, blockchain systems remain constrained by the need to over-provision validator machines to handle peak load. This leads to resource inefficiency, poor cost scaling, and limits on performance. To address these challenges, we introduce Pilotfish, the first scale-out transaction execution engine for blockchains. Pilotfish enables validators to scale horizontally by distributing transaction execution across multiple worker machines, allowing elasticity without compromising consistency or determinism. It integrates seamlessly with the lazy blockchain architecture, completing the missing piece of execution elasticity. To achieve this, Pilotfish tackles several key challenges: ensuring scalable and strongly consistent distributed transactions, handling partial crash recovery with lightweight replication, and maintaining concurrency with a novel versioned-queue scheduling algorithm. Our evaluation shows that Pilotfish scales linearly up to at least eight workers per validator for compute-bound workloads, while maintaining low latency. By solving scalable execution, Pilotfish brings blockchains closer to achieving end-to-end elasticity, unlocking new possibilities for efficient and adaptable blockchain systems."}],"external_id":{"arxiv":["2401.16292"]},"arxiv":1,"publication_identifier":{"isbn":["9783032070234"],"issn":["0302-9743"],"eissn":["1611-3349"]},"date_updated":"2026-02-16T07:56:09Z","year":"2026","publication":"29th International Conference on Financial Cryptography and Data Security","date_created":"2026-01-25T23:01:41Z","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","title":"Pilotfish: Distributed execution for scalable blockchains","date_published":"2026-01-01T00:00:00Z","OA_type":"green","language":[{"iso":"eng"}],"type":"conference","_id":"21044","intvolume":" 15751","scopus_import":"1","citation":{"ieee":"Q.

Perhaps the most surprising features of this population are the presence of Balmer absorption and ubiquitous strong Balmer breaks. Recent models link these features to an active supermassive black hole (SMBH) cocooned in very dense gas (NH ∼ 1024 cm−2). We present a stringent test of such models using VLT/MUSE observations of A2744-45924, the most luminous LRD known to date (LHα ≈ 1044 erg s−1), located behind the Abell-2744 lensing cluster at z = 4.464 (μ = 1.8). We detect a moderately extended Lyα nebula (h ≈ 5.7 pkpc), spatially offset from the point-like Hα seen by JWST by ≈1.6 pkpc. The Lyα emission is narrow (FWHM = 270 ± 15 km s−1), and faint (Lyα = 0.07Hα) compared to Lyα nebulae typically observed around quasars of similar luminosity. We detect compact N IV]λ1486 emission, spatially aligned with Hα, and a spatial shift in the far-UV continuum matching the Lyα offset. We discuss that Hα and Lyα have distinct physical origins: Hα originates from the AGN, while Lyα is powered by star formation. In the environment of A2744-45924, we identified four extended Lyα halos (Δz < 0.02, Δr < 100 pkpc). Their Lyα luminosities match the expectations based on Hα emission, and show no evidence for radiation from A2744-45924 affecting its surroundings. The lack of strong, compact, and broad Lyα and the absence of a luminous extended halo, suggest that the UV AGN light is obscured by dense gas cloaking the SMBH with a covering factor close to unity."}],"PlanS_conform":"1","external_id":{"arxiv":["2505.09542"]},"department":[{"_id":"JoMa"},{"_id":"GradSch"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","corr_author":"1","OA_type":"diamond","language":[{"iso":"eng"}],"file_date_updated":"2026-02-16T07:35:03Z","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_processing_charge":"No","title":"A weak Ly α halo for an extremely bright little red dot.

Given a function from a topological space to $\\mathbb{R}$, TDA provides tools to simplify and study the importance of topological features: in particular, the $l^{th}$-dimensional persistence diagram encodes the $l$-homology in the sublevel set as the function value increases as a set of points in the plane. Given a continuous one-parameter family of such functions, we can combine the persistence diagrams into an object known as a vineyard, which track the evolution of points in the persistence diagram. If we further restrict that family of functions to be periodic, we identify the two ends of the vineyard, yielding a closed vineyard. This allows the study of monodromy, which in this context means that following the family of functions for a period permutes the set of points in a non-trivial way. In this work, given a link and value $l$, we construct a topological space and periodic family of functions such that the closed $l$-vineyard contains this link. This shows that vineyards are topologically as rich as one could possibly hope. Importantly, it has at least two immediate consequences: First, monodromy of any periodicity can occur in a $l$-vineyard, answering a variant of a question by [Arya et al 2024].

Given a function from a topological space to ℝ, TDA provides tools to simplify and study the importance of topological features: in particular, the 𝑙^𝑡ℎ-dimensional persistence diagram encodes the topological changes (or 𝑙-homology) in the sublevel set as the function value increases into a set of points in the plane. Given a continuous one parameter family of such functions, we can combine the persistence diagrams into an object known as a vineyard, which tracks the evolution of points in the persistence diagram as the function changes. If we further restrict that family of functions to be periodic, we identify the two ends of the vineyard, yielding a closed vineyard. This allows the study of monodromy, which in this context means that following the family of functions for a period permutes the set of points in a non-trivial way. Recent work has studied monodromy in the directional persistent homology transform, demonstrating some interesting connections between an input shape and monodromy in the persistent homology transform for 0-dimensional homology embedded in ℝ^2.\r\nIn this work, given a link and a value 𝑙, we construct a topological space (based on the given link) and periodic family of functions on this space (based on the Euclidean distance function), such that the closed 𝑙-vineyard contains this link. This shows that vineyards are topologically as rich as one could possibly hope, suggesting many future directions of work. Importantly, it has at least two immediate consequences we explicitly point out:\r\n1.\tMonodromy of any periodicity can occur in a 𝑙-vineyard for any 𝑙. This answers a variant of a question by Arya and collaborators. To exhibit this as a consequence of our first main result we also reformulate monodromy in a more geometric way, which may be of interest in itself.\r\n2.\tTopologically distinguishing closed vineyards is likely to be difficult (from a complexity theory as well as from a practical perspective) because of the difficulty of knot and link recognition, which have strong connections to many NP-hard problems."}],"external_id":{"arxiv":["2504.11203"]}},{"language":[{"iso":"eng"}],"OA_type":"gold","date_published":"2026-02-11T00:00:00Z","article_processing_charge":"No","title":"On the identifiability of causal graphs with multiple environments","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"has_accepted_license":"1","type":"conference","_id":"21113","date_created":"2026-01-30T08:16:25Z","publication":"The 14th International Conference on Learning Representations","year":"2026","date_updated":"2026-02-16T08:15:11Z","arxiv":1,"external_id":{"arxiv":["2510.13583"]},"abstract":[{"text":"Causal discovery from i.i.d. observational data is known to be generally ill-posed. We demonstrate that if we have access to the distribution induced by a structural causal model, and additional data from (in the best case) only two environments that sufficiently differ in the noise statistics, the unique causal graph is identifiable. Notably, this is the first result in the literature that guarantees the entire causal graph recovery with a constant number of environments and arbitrary nonlinear mechanisms. Our only constraint is the Gaussianity of the noise terms; however, we propose potential ways to relax this requirement. Of interest on its own, we expand on the well-known duality between independent component analysis (ICA) and causal discovery; recent advancements have shown that nonlinear ICA can be solved from multiple environments, at least as many as the number of sources: we show that the same can be achieved for causal discovery while having access to much less auxiliary information.","lang":"eng"}],"department":[{"_id":"FrLo"}],"corr_author":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"OA_place":"publisher","conference":{"end_date":"2026-04-27","start_date":"2026-04-23","name":"ICLR: International Conference on Learning Representations","location":"Rio de Janeiro, Brazil"},"oa_version":"Published Version","month":"02","ddc":["000"],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2510.13583"}],"status":"public","publication_status":"accepted","citation":{"ama":"Montagna F.

We present a computational framework that uses topological data analysis to characterise and compare single-cell morphologies from fluorescence microscopy. Each cell is represented by its contour together with the position of its nucleus, from which we construct a filtration based on a radial distance function and derive a persistence diagram encoding the shape’s topological evolution. The similarity between two cells is quantified using the 2-Wasserstein distance between their diagrams, yielding a shape distance we call the PH distance. We apply this method to two representative experimental systems—primary human mesenchymal stem cells (hMSCs) and HeLa cells—and show that PH distances enable the detection of outliers in those systems, the identification of sub-populations, and the quantification of shape heterogeneity. We benchmark PH against three established contour-based distances (aspect ratio, Fourier descriptors, and elastic shape analysis) and show that PH offers better separation between cell types and greater robustness when clustering heterogeneous populations. Together, these results demonstrate that persistent-homology-based signatures provide a principled and sensitive approach for analysing cell morphology in settings where traditional geometric or image-based descriptors are insufficient."}],"department":[{"_id":"HeEd"}],"corr_author":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"OA_place":"publisher","doi":"10.1371/journal.pcbi.1013890","quality_controlled":"1","oa_version":"Published Version","month":"01","article_type":"original","ddc":["000"],"article_number":"e1013890","status":"public","publication_status":"published","file":[{"creator":"dernst","success":1,"checksum":"3899d929ee9be0453c95524e49992d72","relation":"main_file","file_size":8908746,"access_level":"open_access","file_name":"2026_PloSCompBio_Bleile.pdf","file_id":"21204","date_updated":"2026-02-10T07:13:06Z","date_created":"2026-02-10T07:13:06Z","content_type":"application/pdf"}],"citation":{"apa":"Bokor Bleile, Y., Yadav, P., Koehl, P., & Rehfeldt, F.

Diptera have undergone multiple sex-chromosome turnovers and expansions while maintaining their general chromosomal content, which makes them an ideal clade to study such transitions. We analyzed more than 100 dipteran whole-genome assemblies and identified 4 new lineages that underwent sex-chromosome turnover (in addition to the 5 previously reported). We find that the majority of turnovers happened in the group Schizophora, which tend to have fewer genes on Muller element F (the chromosome homologous to the ancestral insect X chromosome) than lower dipterans, a factor previously hypothesized to facilitate turnover. Most derived X chromosomes have higher GC content than autosomes, consistent with a high prevalence of male achiasmy in Diptera. In addition, an excess of gene movement out of the X is detected for most of these new X chromosomes, and many of these moved genes have high testis expression in Drosophila, suggesting that out-of-X gene movement contributes to the long-term demasculinization of X chromosomes.","lang":"eng"}],"author":[{"last_name":"Layana Franco","full_name":"Layana Franco, Lorena Alexandra","orcid":"0000-0002-1253-6297","first_name":"Lorena Alexandra","id":"02814589-eb8f-11eb-b029-a70074f3f18f"},{"last_name":"Toups","full_name":"Toups, Melissa A","orcid":"0000-0002-9752-7380","first_name":"Melissa A","id":"4E099E4E-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Vicoso","full_name":"Vicoso, Beatriz","orcid":"0000-0002-4579-8306","id":"49E1C5C6-F248-11E8-B48F-1D18A9856A87","first_name":"Beatriz"}],"day":"2","department":[{"_id":"BeVi"}],"publisher":"Institute of Science and Technology Austria","user_id":"68b8ca59-c5b3-11ee-8790-cd641c68093d","corr_author":"1","oa":1,"file_date_updated":"2026-01-30T11:00:56Z","article_processing_charge":"No","title":"Research Data for \"Causes and consequences of sex-chromosome turnovers in Diptera\"","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_published":"2026-01-02T00:00:00Z","doi":"10.15479/AT-ISTA-21116","month":"01","oa_version":"Published Version","_id":"21116","status":"public","type":"research_data","has_accepted_license":"1","keyword":["Schizophora","sex chromosomes","sex-chromosome turnover","Diptera","genomic features","out-of-X movement."]},{"page":"34-55","publication_status":"epub_ahead","citation":{"ieee":"G.

Albritton, S. Armstrong, J.-C. Mourrat, and M. Novack [2], with the notion of second-order lifts of reversible diffusion processes, recently introduced by A. Eberle and the second author [30]. We give an abstract, yet fully constructive, presentation of the theory, so that it can be applied to a large class of linear kinetic equations. As this hypocoercivity technique does not twist the reference norm, we can recover accurate and sharp convergence rates in various models. Among those, adaptive Langevin dynamics (ALD) is discussed in full detail and we show that for near-quadratic potentials, with suitable choices of parameters, it is a near-optimal second-order lift of the overdamped Langevin dynamics. As a further consequence, we observe that the Generalised Langevin Equation (GLE) is also a second-order lift, as the standard (kinetic) Langevin dynamics are, of the overdamped Langevin dynamics. Then, convergence of (GLE) cannot exceed ballistic speed, i.e. the square root of the rate of the overdamped regime. We illustrate this phenomenon with explicit computations in a benchmark Gaussian case."}],"department":[{"_id":"JaMa"}],"oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"OA_type":"green","date_published":"2026-02-01T00:00:00Z","title":"Hypocoercivity meets lifts","article_processing_charge":"No","intvolume":" 20","type":"journal_article","_id":"21132"},{"type":"conference","_id":"21133","has_accepted_license":"1","OA_type":"gold","language":[{"iso":"eng"}],"file_date_updated":"2026-02-16T08:40:29Z","article_processing_charge":"No","title":"A recipe for modular verification of generic tree traversals","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_published":"2026-01-08T00:00:00Z","department":[{"_id":"MiSa"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"publication_identifier":{"isbn":["9798400723414"]},"acknowledgement":"We thank the anonymous reviewers for their insightful suggestions.

Many low-level programs, including some implementations of critical systems like page tables and the web browser DOM, rely on generic tree-traversal functions that traverse tree nodes in a pre-determined order, applying a client-provided operation to each visited node. Developing a general approach to specifying and verifying such traversals is tricky since the client-provided per-node operation can be stateful and may potentially depend on or modify the structure of the tree being traversed.\r\nIn this paper, we present a recipe for (semi-)automated verification of such generic, stateful tree traversals. Our recipe is (a) general: it applies to a range of tree traversals, in particular, pre-, post- and in-order depth-first traversals; (b) modular: parts of a traversal’s proof can be reused in verifying other similar traversals; (c) expressive: using the specification of a tree traversal, we can verify clients that use the traversal in a variety of different ways; and (d) automatable: many proof obligations can be discharged automatically.\r\nAt the heart of our recipe is a novel use of tree zippers to represent a logical abstraction of the tree traversal state, and zipper transitions as an abstraction of traversal steps. We realize our recipe in the RefinedC framework in Rocq, which allows us to verify a number of different tree traversals and their clients written in C."}],"month":"01","conference":{"start_date":"2026-01-12","name":"CPP: Conference on Certified Programs and Proofs","end_date":"2026-01-13","location":"Rennes, France"},"oa_version":"Published Version","status":"public","ddc":["000"],"OA_place":"publisher","quality_controlled":"1","doi":"10.1145/3779031.3779110","author":[{"last_name":"Elbeheiry","full_name":"Elbeheiry, Laila","first_name":"Laila"},{"first_name":"Michael Joachim","id":"510d3901-2a03-11ee-914d-d9ae9011f0a7","last_name":"Sammler","full_name":"Sammler, Michael Joachim"},{"last_name":"Krebbers","full_name":"Krebbers, Robbert","first_name":"Robbert"},{"last_name":"Dreyer","full_name":"Dreyer, Derek","first_name":"Derek"},{"first_name":"Deepak","full_name":"Garg, Deepak","last_name":"Garg"}],"day":"08","publisher":"Association for Computing Machinery","file":[{"success":1,"checksum":"7df99991493e907d83a197151f378e3e","creator":"dernst","date_created":"2026-02-16T08:40:29Z","file_id":"21225","date_updated":"2026-02-16T08:40:29Z","content_type":"application/pdf","file_size":811872,"access_level":"open_access","relation":"main_file","file_name":"2026_CPP_Elbeheiry.pdf"}],"citation":{"ieee":"L.

The adversary can change the honest space by a factor 1+- E with every block (dynamic availability), and “replotting” the space (which allows answering two challenges using the same space) takes as much time as p blocks.\r\nWe prove that no matter what chain selection rule is used, in this game the adversary can create a fork of length o^2 . p/E that will be picked as the winner by the chain selection rule.\r\nWe also provide an upper bound that matches the lower bound up to a factor o. There exists a chain selection rule (albeit a very strange one) which in the above game requires forks of length at least o . p/E\r\nOur results show the necessity of additional assumptions to create a secure PoSpace based longest-chain blockchain.
