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.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"01","OA_place":"publisher","acknowledgement":"We thank Sophie Cloché for her support with the handling of the various datasets.

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. Our results provide a framework for interpreting hydrogen lines in LRDs and similar systems.","lang":"eng"}],"doi":"10.1093/mnras/staf2131","scopus_import":"1","publication_status":"published","_id":"21038","issue":"4","acknowledgement":"The authorsthank the anonymousreferee for constructive comments, which improved the clarity of this paper.

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.","lang":"eng"}],"doi":"10.1021/acsaem.5c03511","scopus_import":"1","publication_status":"published","page":"686-697","issue":"1","_id":"21040"},{"status":"public","publication_identifier":{"eissn":["2475-1421"]},"article_processing_charge":"Yes (via OA deal)","day":"08","department":[{"_id":"MiSa"}],"date_created":"2026-01-25T23:01:40Z","author":[{"last_name":"Mück","first_name":"Niklas","full_name":"Mück, Niklas"},{"first_name":"Aïna Linn","last_name":"Georges","full_name":"Georges, Aïna Linn"},{"last_name":"Dreyer","first_name":"Derek","full_name":"Dreyer, Derek"},{"full_name":"Garg, Deepak","last_name":"Garg","first_name":"Deepak"},{"full_name":"Sammler, Michael Joachim","first_name":"Michael Joachim","last_name":"Sammler","id":"510d3901-2a03-11ee-914d-d9ae9011f0a7"}],"article_type":"original","publisher":"Association for Computing Machinery","language":[{"iso":"eng"}],"type":"journal_article","OA_type":"hybrid","intvolume":"        10","citation":{"short":"N.

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. All our results are mechanized in the Rocq prover.","lang":"eng"}],"doi":"10.1145/3776682","scopus_import":"1","page":"1153-1182","publication_status":"published","_id":"21041"},{"date_created":"2026-01-25T23:01:40Z","department":[{"_id":"KrPi"}],"corr_author":"1","day":"01","publication_identifier":{"issn":["0302-9743"],"eissn":["1611-3349"],"isbn":["9783032070234"]},"article_processing_charge":"No","status":"public","external_id":{"arxiv":["2502.10074"]},"publisher":"Springer Nature","author":[{"full_name":"Neiheiser, Ray","orcid":"0000-0001-7227-8309","first_name":"Ray","last_name":"Neiheiser","id":"f09651b9-fec0-11ec-b5d8-934aff0e52a4"},{"full_name":"Kokoris Kogias, Eleftherios","orcid":"0000-0002-8827-3382","id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30","last_name":"Kokoris Kogias","first_name":"Eleftherios"}],"intvolume":"     15751","OA_type":"green","project":[{"grant_number":"F8502","name":"Interface Theory for Security and Privacy","_id":"34a1b658-11ca-11ed-8bc3-c75229f0241e"},{"grant_number":"ICT22-045","_id":"7bdd2f70-9f16-11ee-852c-b7950bc6d277","name":"SeCure, privAte, and interoperabLe layEr 2"}],"type":"conference","language":[{"iso":"eng"}],"quality_controlled":"1","date_published":"2026-01-01T00:00:00Z","date_updated":"2026-02-12T13:39:07Z","conference":{"location":"Miyakojima, Japan","name":"FC: Financial Cryptography and Data Security","start_date":"2025-04-14","end_date":"2025-04-18"},"citation":{"ista":"Neiheiser R, Kokoris Kogias E. 2026.

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."}],"arxiv":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2502.10074"}]},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2401.16292","open_access":"1"}],"abstract":[{"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.","lang":"eng"}],"arxiv":1,"doi":"10.1007/978-3-032-07024-1_17","scopus_import":"1","page":"287-306","publication_status":"published","_id":"21044","alternative_title":["LNCS"],"OA_place":"repository","month":"01","year":"2026","oa":1,"oa_version":"Preprint","publication":"29th International Conference on Financial Cryptography and Data Security","title":"Pilotfish: Distributed execution for scalable blockchains","volume":15751,"citation":{"ista":"Kniep Q, Kokoris Kogias E, Sonnino A, Zablotchi I, Zhang N. 2026.

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"}],"arxiv":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2510.13583"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"02","OA_place":"publisher","oa":1,"oa_version":"Published Version","has_accepted_license":"1","ddc":["000"],"year":"2026","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"},"publication":"The 14th International Conference on Learning Representations","date_published":"2026-02-11T00:00:00Z","date_updated":"2026-02-16T08:15:11Z","conference":{"start_date":"2026-04-23","end_date":"2026-04-27","location":"Rio de Janeiro, Brazil","name":"ICLR: International Conference on Learning Representations"},"citation":{"mla":"Montagna, Francesco. “On the Identifiability of Causal Graphs with Multiple Environments.” <i>The 14th International Conference on Learning Representations</i>, OpenReview.","short":"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.","lang":"eng"}],"doi":"10.1371/journal.pcbi.1013890","scopus_import":"1","OA_place":"publisher","month":"01","acknowledgement":"We thank Stephan Huckemann, Katharine Turner, Benjamin Eltzner, Stephan Tillmann, Fariza Rashid, Vanessa Robins, and Lamiae Azizi for many useful discussions at various stages of this project.

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."}],"citation":{"mla":"Layana Franco, Lorena Alexandra, et al. <i>Research Data for “Causes and Consequences of Sex-Chromosome Turnovers in Diptera.”</i> Institute of Science and Technology Austria, 2026, doi:<a href=\"https://doi.org/10.15479/AT-ISTA-21116\">10.15479/AT-ISTA-21116</a>.","short":"L.A.

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.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"21133","publication_status":"published","page":"339-352","day":"08","article_processing_charge":"No","status":"public","publication_identifier":{"isbn":["9798400723414"]},"date_created":"2026-02-01T23:01:43Z","department":[{"_id":"MiSa"}],"publisher":"Association for Computing Machinery","author":[{"full_name":"Elbeheiry, Laila","first_name":"Laila","last_name":"Elbeheiry"},{"first_name":"Michael Joachim","id":"510d3901-2a03-11ee-914d-d9ae9011f0a7","last_name":"Sammler","full_name":"Sammler, Michael Joachim"},{"first_name":"Robbert","last_name":"Krebbers","full_name":"Krebbers, Robbert"},{"full_name":"Dreyer, Derek","first_name":"Derek","last_name":"Dreyer"},{"full_name":"Garg, Deepak","first_name":"Deepak","last_name":"Garg"}],"OA_type":"gold","type":"conference","language":[{"iso":"eng"}],"date_updated":"2026-02-16T08:43:24Z","conference":{"location":"Rennes, France","name":"CPP: Conference on Certified Programs and Proofs","start_date":"2026-01-12","end_date":"2026-01-13"},"citation":{"short":"L.

Computationally generating plausible isotropic resolution from anisotropic imaging data would benefit the visual analysis of large-scale volumes. This paper proposes niiv, a self-supervised method for isotropic reconstruction of 3D microscopy data that can quickly produce images at arbitrary output resolutions. The representation embeds a learned latent code within a neural field that describes the implicit higher-resolution isotropic image region. We use an attention-guided latent interpolation approach, which allows flexible information exchange over a local latent neighborhood. Under isotropic volume assumptions, we self-supervise this representation on low-/high-resolution lateral image pairs to reconstruct an isotropic volume from low-resolution axial images. We evaluate our method on simulated and real anisotropic electron (EM) and light microscopy (LM) data. Compared to diffusion-based baselines, niiv shows improved reconstruction quality (+1 dB PSNR) and is over three orders of magnitude faster (1,000x) to infer. Specifically, niiv reconstructs a 128^3 voxel volume in 2/10th of a second, renderable at varying (continuous) high resolutions for display.

The first one is to find k edge-disjoint forests in a directed graph G of maximal size such that the indegree of each vertex in these forests is at most k. We describe a min-max characterization for this problem and show that it can be solved in almost linear time for fixed k, extending the algorithm of [Gabow, 1995]. Specifically, the complexity is O(kδm log n), where n, m are the number of vertices and edges in G respectively, and δ = max{1, k − kG}, where kG is the edge connectivity of the graph. Using our solution to this problem, we improve complexities for two existing applications:(1) k-forest problem: find k forests in an undirected graph G maximizing the number of edges in their union. We show how to solve this problem in O(k3 min{kn, m} log2 n + k · MAXFLOW(m, m) log n) time, breaking the Ok(n3/2) complexity barrier of previously known approaches.(2) Directed edge-connectivity augmentation problem: find a smallest set of directed edges whose addition to the given directed graph makes it strongly k-connected. We improve the deterministic complexity for this problem from O(kδ(m + δn) log n) [Gabow, STOC 1994] to O(kδm log n). A similar approach with the same complexity also works for the undirected version of the problem.","lang":"eng"}],"arxiv":1,"OA_place":"repository","month":"01","publisher":"Society for Industrial and Applied Mathematics","external_id":{"arxiv":["2409.20314"]},"author":[{"id":"b25f2ab2-1fed-11ee-8599-fe02d211784f","last_name":"Arkhipov","first_name":"Pavel","full_name":"Arkhipov, Pavel"},{"first_name":"Vladimir","id":"3D50B0BA-F248-11E8-B48F-1D18A9856A87","last_name":"Kolmogorov","full_name":"Kolmogorov, Vladimir"}],"department":[{"_id":"VlKo"}],"date_created":"2026-02-05T10:51:34Z","corr_author":"1","day":"07","status":"public","article_processing_charge":"No","publication_identifier":{"eisbn":["9781611978971"]},"quality_controlled":"1","date_published":"2026-01-07T00:00:00Z","citation":{"short":"P.

Sugars have long been recognized in regulating flowering; however, the intrinsic connection between carbohydrate metabolism and vernalization response remains largely unexplored. Here, we identify a fructose 1,6-bisphosphate aldolase (FBA) encoding gene, HtL1/FBA10, as a modulator of heading time variation based on a genome-wide association study utilizing wheat core germplasm collections. Evolutionary analysis shows a decrease in the proportion of haplotype-2 of HtL1, which is linked to delayed flowering, in Chinese and American wheat varieties compared to landraces. Vernalization reduces HtL1/FBA10 phosphorylation levels and  increases  its O-GlcNAcylation, which in turn enhances its enzymatic activity and facilitates VERNALIZATION 1 (VRN1) transcription by regulating histone acetylation at the VRN1 locus. Our findings provide mechanistic insights into the interplay between glucose metabolism and the epigenetic regulation of vernalization in winter wheat.","lang":"eng"}],"publication_status":"published","pmid":1,"_id":"21158","acknowledgement":"This work was supported by the Basic Science Center Project of National Natural Science Foundation of China (32388201) to K.C and the National Natural Science Foundation of China (31970331) to L.X.

Later work by Sárközy,\r\nSelkow and Szemerédi showed that in fact Dirac graphs have many Hamilton cycles\r\nand perfect matchings, culminating in a result of Cuckler and Kahn that gives a precise\r\ndescription of the numbers of Hamilton cycles and perfect matchings in a Dirac graph\r\nG (in terms of an entropy-like parameter of G). In this paper we extend Cuckler\r\nand Kahn’s result to perfect matchings in hypergraphs. For positive integers d < k,\r\nand for n divisible by k, let md (k, n) be the minimum d-degree that ensures the\r\nexistence of a perfect matching in an n-vertex k-uniform hypergraph. In general, it is\r\nan open question to determine (even asymptotically) the values of md (k, n), but we are\r\nnonetheless able to prove an analogue of the Cuckler–Kahn theorem, showing that if\r\nan n-vertex k-uniform hypergraph G has minimum d-degree at least (1+γ )md (k, n)\r\n(for any constantγ > 0), then the number of perfect matchings in G is controlled by\r\nan entropy-like parameter of G.

One potential pairing mechanism, invoked in the related re-entrant superconductors UCoGe and URhGe, involves transverse fluctuations of a ferromagnetic order parameter. However, the requisite ferromagnetic order - present in both UCoGe and URhGe - is absent in UTe2, and magnetization measurements show no sign of strong fluctuations. Here, we measure the magnetotropic susceptibility of UTe2 across two field-angle planes. This quantity is sensitive to the magnetic susceptibility in a direction transverse to the applied magnetic field - a quantity that is not accessed in conventional magnetization measurements. We observe a very large decrease in the magnetotropic susceptibility over a broad range of field orientations, indicating a large increase in the transverse magnetic susceptibility. The three superconducting phases of UTe2, including the high-field re-entrant phase, surround this region of enhanced susceptibility in the field-angle phase diagram. The strongest transverse susceptibility is found near the critical end point of the high-field metamagnetic transition, suggesting that quantum critical fluctuations of a field-induced magnetic order parameter may be responsible for the large transverse susceptibility, and may provide a pairing mechanism for field-induced superconductivity in UTe2."}],"doi":"10.15479/AT-ISTA-21174","keyword":["transverse magnetic susceptibility","magnetotropic","superconductivity","magnetic fluctuations"],"contributor":[{"first_name":"Valeska","contributor_type":"project_member","last_name":"Zambra","id":"467ed36b-dc96-11ea-b7c8-b043a380b282","orcid":"0000-0002-8806-5719"}],"_id":"21174","status":"public","article_processing_charge":"Yes","related_material":{"record":[{"id":"21845","relation":"used_in_publication","status":"public"}],"link":[{"relation":"preprint","url":"https://arxiv.org/pdf/2506.08984"}]},"day":"19","corr_author":"1","department":[{"_id":"KiMo"}],"date_created":"2026-02-09T12:04:20Z","author":[{"full_name":"Modic, Kimberly A","orcid":"0000-0001-9760-3147","first_name":"Kimberly A","id":"13C26AC0-EB69-11E9-87C6-5F3BE6697425","last_name":"Modic"}],"publisher":"Institute of Science and Technology Austria","type":"research_data","OA_type":"free access","project":[{"name":"Gaining leverage with spin liquids and superconductors","grant_number":"101078696","_id":"bd968c70-d553-11ed-ba76-cde40b0aba64"}],"citation":{"mla":"Modic, Kimberly A. <i>Research Data for “Giant Transverse Magnetic Fluctuations at the Edge of Re-Entrant Superconductivity in UTe2.”</i> Institute of Science and Technology Austria, 2026, doi:<a href=\"https://doi.org/10.15479/AT-ISTA-21174\">10.15479/AT-ISTA-21174</a>.","short":"K.A.
