Here, we report a colloidal hot-injection synthesis of ternary cesium copper selenide (CsCu5Se3) nanocrystals (NCs), achieving precise control over phase, size, and morphology through tailored precursor-ligand modulation. This strategy enabled systematic exploration of stable and metastable Cs–Cu–Se phases and mechanistic investigation of nucleation and growth, providing insight into phase modulation and dimensional control at the nanoscale. CsCu5Se3 NCs exhibit low lattice thermal conductivity (∼0.5 Wm–1K–1) and an experimental zT of 0.27 at 718 K. Complementary first-principles calculations, consistent with experimental electronic and optical responses, predict a zT of 1.05 at 1000 K. These findings elucidate the formation dynamics of CsCu5Se3 and establish ABZ (A = alkali, B = metal, Z = chalcogen) NCs as tunable platforms for advanced functional applications.","lang":"eng"}],"page":"481-488","article_type":"letter_note","OA_type":"closed access","issue":"1","title":"Layered alkali-copper selenides: Deciphering thermoelectric properties and reaction pathways for nanostructuring β-CsCu5Se3","article_processing_charge":"No","oa_version":"None","publication_status":"published","date_created":"2026-01-18T23:02:43Z","date_updated":"2026-01-19T08:43:21Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"21001","year":"2026","month":"01","publication_identifier":{"eissn":["2380-8195"]},"citation":{"short":"N.N.

Despite intensive research efforts during the past decade, catalytic methods employing this approach are still mostly confined to activated starting materials and require high catalyst loadings due to the low catalytic activity of NiI and undesired catalyst deactivation events. This article highlights recent advances in the field toward solving these long-standing challenges. We survey strategies that streamline the generation of catalytically competent NiI species from bench-stable NiII precatalysts, and discuss mechanistic studies that shed light on deactivation pathways and the rate-determining oxidative addition of aryl halides. In the final section, we highlight recently developed synthetic methodologies, which provide evidence that limitations can indeed be addressed by working at elevated temperatures, employing alternative electrophiles, harnessing the benefits of additives, or fine-tuning the metal’s reactivity through the ligand field.","lang":"eng"}],"page":"866-881","date_created":"2026-01-20T10:04:57Z","oa_version":"Published Version","publication_status":"published","article_processing_charge":"Yes (via OA deal)","title":"Advances in NiI/NiIII-catalyzed C(sp2)–heteroatom cross-couplings","issue":"2","OA_type":"hybrid","oa":1,"scopus_import":"1","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"},"status":"public","has_accepted_license":"1","department":[{"_id":"BaPi"},{"_id":"GradSch"}],"publisher":"American Chemical Society","project":[{"_id":"8f1d607d-16d5-11f0-9cad-ab453295ba5e","grant_number":"PAT 1250924","name":"Photoactive ligands for transformative nickel catalysis"}],"corr_author":"1","author":[{"full_name":"Bena, Aleksander","last_name":"Bena","id":"4197c39e-e8ec-11ed-86cb-afed934cd664","first_name":"Aleksander"},{"orcid":"0000-0001-8689-388X","full_name":"Pieber, Bartholomäus","last_name":"Pieber","first_name":"Bartholomäus","id":"93e5e5b2-0da6-11ed-8a41-af589a024726"}],"language":[{"iso":"eng"}],"quality_controlled":"1","intvolume":"        16","publication":"ACS Catalysis","acknowledgement":"We gratefully acknowledge the Institute of Science and Technology Austria for generous financial support.

Our experiment designs are motivated by land‐ocean heterogeneity of atmospheric convection. The steady and oscillating forcings are idealizations of ocean and land conditions, respectively, based on their differences in heat capacities. In both kinds of simulations, the diurnal mean SST and SOLIN are the same, and both SST and SOLIN are only varied in time (i.e., they are spatially homogeneous at any given time). We find that diurnally oscillating forcing accelerates CSA. Stronger long‐wave cooling in dry regions at night and during the warm SST phase (late afternoon) both allow the long‐wave feedback, known to favor aggregation, to intensify compared to steady forcing simulations. In addition to the long‐wave, reduced short‐wave warming in dry regions (during the day) further enhances radiative cooling there compared to moist regions. Overall, the radiative cooling is enhanced in dry regions compared to neighboring moist convective regions. A dry subsidence is driven by this net radiative (short‐wave plus long‐wave) cooling, consistent with earlier work on CSA. Stronger radiative cooling allows stronger subsidence which allows low‐level circulation to more efficiently transport moisture and energy up‐gradient, driving convection to aggregate faster. We also note a sensitivity of our experimental setup to initial conditions, more so at warmer SST. This stochastic behavior might be critical in reconciling the differences of opinion regarding the response of convection aggregation to oscillating SST forcing."}],"file_date_updated":"2026-01-21T08:39:01Z","article_type":"original","issue":"1","OA_type":"gold","date_created":"2026-01-20T10:08:54Z","publication_status":"published","oa_version":"Published Version","article_processing_charge":"Yes","title":"Convective self‐aggregation in diurnally oscillating sea surface temperature and solar forcing experiments","_id":"21013","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2026-01-21T08:41:19Z","year":"2026","OA_place":"publisher","PlanS_conform":"1","month":"01","acknowledged_ssus":[{"_id":"ScienComp"}],"ec_funded":1,"publication_identifier":{"eissn":["1942-2466"]},"volume":18,"ddc":["550"],"citation":{"mla":"GOSWAMI, BIDYUT B., et al. “Convective Self‐aggregation in Diurnally Oscillating Sea Surface Temperature and Solar Forcing Experiments.” <i>Journal of Advances in Modeling Earth Systems</i>, vol. 18, no. 1, e2024MS004576, Wiley, 2026, doi:<a href=\"https://doi.org/10.1029/2024ms004576\">10.1029/2024ms004576</a>.","chicago":"GOSWAMI, BIDYUT B, Ziyin Lu, and Caroline J Muller. “Convective Self‐aggregation in Diurnally Oscillating Sea Surface Temperature and Solar Forcing Experiments.” <i>Journal of Advances in Modeling Earth Systems</i>.

Here we show that in zebrafish, the geometry of the fertilized egg—specifically its curvature and volume—serves as a critical initial condition triggering a cascade of events that influence development. The embryo geometry guides patterned asymmetric cell divisions in the blastoderm, generating radial gradients of cell volume and nucleocytoplasmic ratio. These gradients generate mitotic phase waves, with the nucleocytoplasmic ratio determining individual cell cycle periods independently of other cells. We demonstrate that reducing cell autonomy reshapes these waves, emphasizing the instructive role of geometry-derived volume patterns in setting the intrinsic period of the cell cycle oscillator. In addition to organizing cell cycles, early embryo geometry spatially patterns zygotic genome activation at the midblastula transition, a key step in establishing embryonic autonomy. Disrupting the embryo shape alters the zygotic genome activation pattern and causes ectopic germ layer specification, underscoring the developmental significance of geometry. Together, our findings reveal a symmetry-breaking function of early embryo geometry in coordinating cell cycle and transcriptional patterning."}],"external_id":{"oaworkid":["W7118187193"]},"publication_status":"published","oa_version":"Published Version","date_created":"2026-01-20T10:12:19Z","related_material":{"link":[{"url":"https://ista.ac.at/en/news/geometry-shapes-life/","relation":"research_data","description":"News on ISTA website"}]},"title":"Geometry-driven asymmetric cell divisions pattern cell cycles and zygotic genome activation in the zebrafish embryo","article_processing_charge":"Yes (via OA deal)","OA_type":"hybrid","year":"2026","OA_place":"publisher","PlanS_conform":"1","_id":"21015","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_updated":"2026-04-28T12:55:30Z","ec_funded":1,"publication_identifier":{"eissn":["1745-2481"],"issnl":[" 1745-2473"],"issn":["1745-2473"]},"month":"01","acknowledged_ssus":[{"_id":"PreCl"},{"_id":"Bio"},{"_id":"ScienComp"},{"_id":"LifeSc"}],"quality_controlled":"1","language":[{"iso":"eng"}],"publication":"Nature Physics","acknowledgement":"We thank N.

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"}],"external_id":{"pmid":["41550270"]},"publication_status":"published","date_created":"2026-01-25T23:01:38Z","oa_version":"Published Version","title":"No decrease of tropical convection in individual deep convective systems with global warming","article_processing_charge":"Yes","OA_type":"gold","oa":1,"scopus_import":"1","tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"status":"public","has_accepted_license":"1","department":[{"_id":"CaMu"}],"publisher":"Springer Nature","project":[{"_id":"629205d8-2b32-11ec-9570-e1356ff73576","grant_number":"805041","name":"Organization of CLoUdS, and implications of Tropical  cyclones and for the Energetics of the tropics, in current and waRming climate","call_identifier":"H2020"}],"author":[{"last_name":"Bolot","first_name":"Maximilien","full_name":"Bolot, Maximilien"},{"last_name":"Roca","first_name":"Rémy","full_name":"Roca, Rémy"},{"last_name":"Fiolleau","first_name":"Thomas","full_name":"Fiolleau, Thomas"},{"id":"f978ccb0-3f7f-11eb-b193-b0e2bd13182b","first_name":"Caroline J","last_name":"Muller","orcid":"0000-0001-5836-5350","full_name":"Muller, Caroline J"}]},{"year":"2026","PlanS_conform":"1","OA_place":"publisher","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"21038","date_updated":"2026-02-12T12:56:33Z","publication_identifier":{"issn":["0035-8711"],"eissn":["1365-2966"]},"month":"02","language":[{"iso":"eng"}],"quality_controlled":"1","intvolume":"       545","acknowledgement":"The authorsthank the anonymousreferee for constructive comments, which improved the clarity of this paper.

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"}],"external_id":{"arxiv":["2508.08768"]},"publication_status":"published","date_created":"2026-01-25T23:01:39Z","oa_version":"Published Version","article_processing_charge":"Yes","title":"Impact of resonance, Raman, and Thomson scattering on hydrogen line formation in Little Red Dots","arxiv":1,"issue":"4","OA_type":"gold"},{"year":"2026","OA_place":"repository","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"21039","date_updated":"2026-02-12T12:41:18Z","publication_identifier":{"eissn":["1477-9129"],"issn":["0950-1991"]},"month":"01","language":[{"iso":"eng"}],"quality_controlled":"1","intvolume":"       153","publication":"Development","acknowledgement":"We thank Pierre Léopold, Tatsushi Igaki, Erik Storkebaum, Tobias Reiff, Masayuki Miura, Xiaohang Yang, Mikio Furuse, Bloomington Drosophila Stock Center and Developmental Studies Hybridoma Bank for providing us with fly stocks and reagents.

However, the molecular mechanism enabling such plasticity remains largely unexplored. 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. Our work identifies Xrp1 as a crucial regulator that coordinates damage-induced signaling and transcriptional reprogramming, enabling the reactivation of cellular plasticity in differentiated cells.","lang":"eng"}],"external_id":{"pmid":["41392708"]},"publication_status":"published","oa_version":"Preprint","date_created":"2026-01-25T23:01:39Z","title":"Xrp1 drives damage-induced cellular plasticity of enteroendocrine cells in the adult Drosophila midgut","article_processing_charge":"No","issue":"2","OA_type":"green"},{"author":[{"full_name":"Busato, Matteo","first_name":"Matteo","last_name":"Busato"},{"first_name":"Mariarosaria","last_name":"Tuccillo","full_name":"Tuccillo, Mariarosaria"},{"first_name":"Arcangelo","last_name":"Celeste","full_name":"Celeste, Arcangelo"},{"full_name":"Tofoni, Alessandro","last_name":"Tofoni","first_name":"Alessandro"},{"last_name":"Silvestri","first_name":"Laura","full_name":"Silvestri, Laura"},{"full_name":"D’Angelo, Paola","first_name":"Paola","last_name":"D’Angelo"},{"full_name":"Freunberger, Stefan Alexander","orcid":"0000-0003-2902-5319","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","first_name":"Stefan Alexander","last_name":"Freunberger"},{"last_name":"Brutti","first_name":"Sergio","full_name":"Brutti, Sergio"}],"corr_author":"1","department":[{"_id":"StFr"}],"publisher":"American Chemical Society","has_accepted_license":"1","status":"public","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"},"oa":1,"scopus_import":"1","OA_type":"hybrid","issue":"1","title":"Structural rearrangements of a Cobalt-free Lithium-rich layered oxide cathode during formation","article_processing_charge":"Yes (via OA deal)","publication_status":"published","date_created":"2026-01-25T23:01:40Z","oa_version":"Published Version","abstract":[{"lang":"eng","text":"Formation during the first cycles of Li-rich layered oxide (LRLO) cathode materials consolidates the interphase and leads to structural changes that are decisive for long-term cyclability. 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."}],"page":"686-697","file":[{"file_id":"21222","file_size":5977526,"date_updated":"2026-02-12T13:55:28Z","success":1,"date_created":"2026-02-12T13:55:28Z","access_level":"open_access","checksum":"81272c19df41c696c1737168d3ea8c16","creator":"dernst","relation":"main_file","content_type":"application/pdf","file_name":"2026_AppliedEnergyMaterials_Busato.pdf"}],"article_type":"original","file_date_updated":"2026-02-12T13:55:28Z","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"LifeSc"}],"month":"01","publication_identifier":{"eissn":["2574-0962"]},"date_updated":"2026-02-12T14:04:04Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"21040","PlanS_conform":"1","OA_place":"publisher","year":"2026","doi":"10.1021/acsaem.5c03511","day":"12","date_published":"2026-01-12T00:00:00Z","citation":{"apa":"Busato, M., Tuccillo, M., Celeste, A., Tofoni, A., Silvestri, L., D’Angelo, P., … Brutti, S.

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."}],"page":"1153-1182","file":[{"file_size":1058876,"file_id":"21221","date_updated":"2026-02-12T13:51:03Z","checksum":"79be391061efbf9542638996959ce11a","date_created":"2026-02-12T13:51:03Z","success":1,"access_level":"open_access","creator":"dernst","file_name":"2026_ProcACMProgrammingLanguages_Mueck.pdf","relation":"main_file","content_type":"application/pdf"}],"article_type":"original","file_date_updated":"2026-02-12T13:51:03Z","OA_type":"hybrid","article_processing_charge":"Yes (via OA deal)","title":"Endangered by the language but saved by the compiler: Robust safety via semantic back-translation","oa_version":"Published Version","publication_status":"published","date_created":"2026-01-25T23:01:40Z","has_accepted_license":"1","status":"public","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"},"oa":1,"scopus_import":"1","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"},{"first_name":"Deepak","last_name":"Garg","full_name":"Garg, Deepak"},{"id":"510d3901-2a03-11ee-914d-d9ae9011f0a7","first_name":"Michael Joachim","last_name":"Sammler","full_name":"Sammler, Michael Joachim"}],"publisher":"Association for Computing Machinery","department":[{"_id":"MiSa"}],"type":"journal_article","citation":{"ama":"Mück N, Georges AL, Dreyer D, Garg D, Sammler MJ.

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.

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"}],"external_id":{"arxiv":["2401.16292"]},"page":"287-306","publisher":"Springer Nature","author":[{"last_name":"Kniep","first_name":"Quentin","full_name":"Kniep, Quentin"},{"last_name":"Kokoris Kogias","id":"f5983044-d7ef-11ea-ac6d-fd1430a26d30","first_name":"Eleftherios","full_name":"Kokoris Kogias, Eleftherios","orcid":"0000-0002-8827-3382"},{"full_name":"Sonnino, Alberto","last_name":"Sonnino","first_name":"Alberto"},{"first_name":"Igor","last_name":"Zablotchi","full_name":"Zablotchi, Igor"},{"full_name":"Zhang, Nuda","first_name":"Nuda","last_name":"Zhang"}],"alternative_title":["LNCS"],"oa":1,"scopus_import":"1","conference":{"name":"FC: Financial Cryptography and Data Security","end_date":"2025-04-18","location":"Miyakojima, Japan","start_date":"2025-04-14"},"status":"public","date_published":"2026-01-01T00:00:00Z","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2401.16292","open_access":"1"}],"day":"01","doi":"10.1007/978-3-032-07024-1_17","language":[{"iso":"eng"}],"quality_controlled":"1","intvolume":"     15751","publication":"29th International Conference on Financial Cryptography and Data Security","volume":15751,"type":"conference","citation":{"chicago":"Kniep, Quentin, Eleftherios Kokoris Kogias, Alberto Sonnino, Igor Zablotchi, and Nuda Zhang. “Pilotfish: Distributed Execution for Scalable Blockchains.” In <i>29th International Conference on Financial Cryptography and Data Security</i>, 15751:287–306.

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."}],"file":[{"file_size":8908746,"file_id":"21204","date_updated":"2026-02-10T07:13:06Z","checksum":"3899d929ee9be0453c95524e49992d72","access_level":"open_access","date_created":"2026-02-10T07:13:06Z","success":1,"file_name":"2026_PloSCompBio_Bleile.pdf","relation":"main_file","content_type":"application/pdf","creator":"dernst"}],"pmid":1,"file_date_updated":"2026-02-10T07:13:06Z","article_type":"original","OA_type":"gold","article_processing_charge":"Yes","title":"Persistence diagrams as morphological signatures of cells: A method to measure and compare cells within a population","oa_version":"Published Version","date_created":"2026-01-30T10:36:32Z","publication_status":"published","related_material":{"link":[{"relation":"software","url":"https://github.com/yossibokorbleile/correa"}]},"status":"public","has_accepted_license":"1","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"},"scopus_import":"1","oa":1,"author":[{"full_name":"Bleile, Yossi","orcid":"0000-0002-4861-9174","first_name":"Yossi","id":"920a7385-7995-11ef-9bfd-8c434cd8f3c2","last_name":"Bleile"},{"full_name":"Yadav, Pooja","first_name":"Pooja","last_name":"Yadav"},{"first_name":"Patrice","last_name":"Koehl","full_name":"Koehl, Patrice"},{"full_name":"Rehfeldt, Florian","first_name":"Florian","last_name":"Rehfeldt"}],"corr_author":"1","department":[{"_id":"HeEd"}],"publisher":"Public Library of Science","citation":{"ieee":"Y.

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":{"ista":"Layana Franco LA, Toups MA, Vicoso B. 2026.

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"}],"page":"339-352","file_date_updated":"2026-02-16T08:40:29Z","month":"01","publication_identifier":{"isbn":["9798400723414"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"21133","date_updated":"2026-02-16T08:43:24Z","year":"2026","OA_place":"publisher","doi":"10.1145/3779031.3779110","date_published":"2026-01-08T00:00:00Z","day":"08","ddc":["000"],"type":"conference","citation":{"apa":"Elbeheiry, L., Sammler, M.

Our bounds show that an additional primitive like that is necessary."}],"external_id":{"arxiv":["2505.14891"]},"alternative_title":["LNCS"],"corr_author":"1","author":[{"full_name":"Baig, Mirza Ahad","last_name":"Baig","id":"3EDE6DE4-AA5A-11E9-986D-341CE6697425","first_name":"Mirza Ahad"},{"full_name":"Pietrzak, Krzysztof Z","orcid":"0000-0002-9139-1654","first_name":"Krzysztof Z","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","last_name":"Pietrzak"}],"project":[{"_id":"34a34d57-11ca-11ed-8bc3-a2688a8724e1","name":"Security and Privacy by Design for Complex Systems","grant_number":"F8509"}],"publisher":"Springer Nature","department":[{"_id":"KrPi"}],"status":"public","conference":{"location":"Miyakojima, Japan","start_date":"2025-04-14","name":"FC: Financial Cryptography and Data Security","end_date":"2025-04-18"},"scopus_import":"1","oa":1}]
