However, existing datasets focus mainly on mainstream social media platforms whose structures are shaped notably by algorithmic recommendations. This raises an important question: would alternative, decentralized social networks exhibit different properties? We address this by studying the Fediverse; a collection of decentralized social networks (such as Mastodon and Lemmy). These platforms differ fundamentally from for-profit social media, notably in decentralization and absence of recommendation algorithms, which may yield distinct graph structures. We introduce Fedivertex, a dataset of over 400 graphs from seven decentralized networks, collected weekly over six months. The dataset, released with a companion Python package to facilitate its use, supports research on temporal and structural aspects of decentralized social networks. In particular, we benchmark applications to decentralized machine learning and community detection."}]},{"OA_type":"gold","author":[{"first_name":"Tom-Lukas","full_name":"Breitkopf, Tom-Lukas","last_name":"Breitkopf"},{"full_name":"Dallot, Julien","first_name":"Julien","last_name":"Dallot"},{"orcid":"0000-0003-4268-7368","full_name":"El-Hayek, Antoine","first_name":"Antoine","last_name":"El-Hayek","id":"888a098e-fcac-11ee-aff7-d347be57b725"},{"first_name":"Stefan","full_name":"Schmid, Stefan","last_name":"Schmid"}],"OA_place":"publisher","acknowledgement":"Funded by the European union.

Before our work, the state\r\ncomplexity (the minimum number of states required per agent) was\r\nonly known to be between Ω(𝑘\r\n2\r\n) and𝑂(𝑘\r\n7\r\n). Our main contribution\r\nis a population protocol that solves the relative majority problem\r\nwith 𝑘\r\n3\r\nstates. We achieve this result with a new protocol called\r\nCircles. While prior approaches in the literature relied on duels of\r\nagents to find the majority color — an approach that proved effective\r\nfor the case with two colors — Circles partitions the agents into\r\ncircular linked lists of decreasing sizes, with the property that no\r\ntwo agents with the same initial color lie in the same circle. We\r\nshow that Circles always correctly computes the desired structure\r\nagainst the most adversarial of schedulers (weakly fair). We then\r\nshow that a trivial extension of Circles solves the relative majority\r\nproblem. We extend our protocol to handle various tie-breaking\r\nmechanisms or to support the case where the agents do not share a\r\nprior ordering of the colors. Finally, we show that a modification of\r\nCircles solves the ranking problem with 2 · 𝑘^4\r\nstates, where each\r\nagent must output the rank of its initial color in the population."}],"year":"2026"},{"volume":26,"citation":{"apa":"Ishida, S., &#38; Lavenant, H.

However, it suffers from poor cycle life associated with the rock-salt phase transformation. This study presents a straightforward synthesis approach to enhance the electrochemical performance of LiNi0.5Mn1.5O4 through a synergistic solid-state modification with LiF and AlF3. This dual modification promotes rapid Li⁺ diffusion, enables near-complete delithiation/lithiation, approaching the theoretical capacity of disordered LiNi0.5Mn1.5O4, and, more importantly, effectively mitigates the formation of the rock-salt phase, thereby enhancing structural stability, as confirmed by operando X-ray absorption spectroscopy (XAS) and synchrotron X-ray diffraction (SXRD). As a result, the optimized LiNi0.5Mn1.5O4 (10 mg AlF3 + 30 mg LiF) delivers high reversible capacities of 142.1, 139.1, 129.2, 121.6, 110.3, 93.5, and 76.1 mAh∙g−1 at 0.2C, 0.5C, 1.0C, 2.0C, 3.0C, 4.0C, and 5.0C, respectively. Full cells using graphite as the anode and a high-loading cathode exhibit excellent cycling performance. They retain 80% of their capacity after 200 cycles at 0.5C within a voltage window of 3.5–4.9 V with cathode loading of 11 mg∙cm−2. The findings of this study will significantly advance high-power LiNi0.5Mn1.5O4 materials, offering improved battery life and thereby enhancing their potential for practical applications."}],"issue":"11","year":"2026","intvolume":"        13","PlanS_conform":"1","status":"public","project":[{"name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery","_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A"}],"DOAJ_listed":"1","date_created":"2025-12-21T23:01:35Z","das_tickbox":"1","file_date_updated":"2026-07-23T06:15:51Z","article_processing_charge":"Yes","ddc":["540"],"pmid":1,"scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","supplementarymaterial":"yes","date_published":"2026-02-23T00:00:00Z","keyword":["disordered spinel LiNi0.5Mn1.5O4 (LNMO)","generation 3b batteries","operando SXRD","operando XAS","rock-salt","solid-state synthesis"],"external_id":{"pmid":["41388041"]},"oa":1,"quality_controlled":"1","file":[{"content_type":"application/pdf","file_id":"22387","checksum":"37adc3eff9ad9f8f9b55cfe66883f36d","success":1,"access_level":"open_access","relation":"main_file","file_name":"2026_AdvancedScience_Chang.pdf","creator":"dernst","date_updated":"2026-07-23T06:15:51Z","date_created":"2026-07-23T06:15:51Z","file_size":6353217}],"publisher":"Wiley","date_updated":"2026-07-23T06:18:43Z","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"publication":"Advanced Science","article_type":"original","month":"02","researchdata_availability":"upon request","article_number":"e15962","dataavailabilitystatement":"The data that support the findings of this study are available from the corresponding author upon reasonable request","has_accepted_license":"1","day":"23","department":[{"_id":"MaIb"}],"publication_identifier":{"eissn":["2198-3844"]},"language":[{"iso":"eng"}],"_id":"20851","publication_status":"published","oa_version":"Published Version","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"type":"journal_article","title":"Mitigating the rock-salt phase transformation in disordered LNMO through synergetic solid-state AlF3/LiF modifications","citation":{"short":"X.

Yet, how temperature regulates migration dynamics at the single-cell level has remained poorly understood. Using zebrafish embryos and mouse tissue explants, we found that temperature positively regulates leukocyte migration speed, exploration, and arrival frequencies to wounds and lymph vessels. Complementary 2D and 3D cultures revealed that this thermokinetic control of cell migration is conserved across immune cell types, independently of the 3D tissue environment. By applying precise (sub-)cellular temperature modulation, we identified a rapid and reversible thermo-response that depends on myosin II activity. Small physiological increases in temperature (1°C –2°C), as present during fever-like conditions, profoundly increased immune responses by accelerating arrival times at lymphatic vessels and tissue wounds. These findings identify myosin-II-dependent actomyosin contractility as a critical mechanical structure regulating single-cell thermo-adaptability, with physiological implications for tuning the speed of immune responses in vivo.","lang":"eng"}],"year":"2026","external_id":{"pmid":["41192429"]},"keyword":["thermobiology","cell migration","thermo-adaptability of immune cells"],"quality_controlled":"1","oa":1,"file":[{"success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"22388","checksum":"52fd52d2d19a4514f8fcc1b40f420ca2","date_updated":"2026-07-23T06:26:25Z","date_created":"2026-07-23T06:26:25Z","file_size":12342817,"creator":"dernst","file_name":"2026_DevelopmentalCell_CompanyGarrido.pdf"}],"publisher":"Elsevier","das_tickbox":"1","date_created":"2025-12-28T23:01:27Z","article_processing_charge":"Yes (in subscription journal)","file_date_updated":"2026-07-23T06:26:25Z","pmid":1,"ddc":["570"],"date_published":"2026-02-11T00:00:00Z","supplementarymaterial":"yes","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","scopus_import":"1","dataavailabilitystatement":"This study did not generate new unique reagents.

Here, we expand DESC to water-soluble azopolymers obtained by RAFT polymerization and systematically investigate the interplay between the polymer structure and DESC efficiency. Using this approach, we achieved as much as 85% of the direct photoexcitation (UV) switching efficiency, while utilizing low-energy (yellow) light.

Our proof consists in generalizing dimension bounds on jet spaces of this fiber, which were introduced by Budur. We also transfer the rational singularities property to other moduli spaces of objects in 2-Calabi-Yau categories, based on recent work of Davison. This has interesting arithmetic applications on quiver moment maps and moduli spaces of objects in 2-Calabi-Yau categories. First, we generalize results of Wyss on the asymptotic behaviour of counts of jets of quiver moment maps over finite fields. Moreover, we interpret the limit of counts of jets on a given moduli space as its p-adic volume under a canonical measure analogous to the measure built by Carocci, Orecchia and Wyss on certain moduli spaces of coherent sheaves."}],"year":"2026","OA_place":"publisher","OA_type":"hybrid","author":[{"id":"19f1e3bf-c59a-11ee-a1af-ed269948817b","full_name":"Vernet, Tanguy","first_name":"Tanguy","last_name":"Vernet"}],"acknowledgement":"I would like to warmly thank Dimitri Wyss for his guidance and supervision and Nero Budur for helpful discussions and answering all my questions on his previous works.

Herein, we report a ligand-free aqueous synthesis of Te-doped CuAgSe (CuAgSe1-xTex), where structural and electronic modulation improve carrier transport and suppress phonon propagation. Ex-situ time-resolved X-ray diffraction reveals a spontaneous growth mechanism, while density functional theory calculations show that Te-5s and 5p orbitals hybridization generates localized states and an asymmetric density of states, thereby enhancing the Seebeck coefficient. Electron microscopy and strain analyses confirm that Te-doping introduces a high density of lattice dislocations and grain boundaries, leading to a reduced lattice thermal conductivity of 0.11 W m−1K−1 at 443 K. These synergistic effects translate into device-level performance—the first integrated CuAgSe thermoelectric modules, exhibit a maximum cooling temperature difference of 27.3 K, and power density of 0.34 W cm−2 with a conversion efficiency of 3.6% at a modest temperature gradient of 136 K. These results demonstrate that CuAgSe1-xTex enables efficient energy harvesting and localized cooling under small temperature gradient, underscoring the importance of structural and electronic design beyond conventional zT benchmarks."}],"issue":"25","year":"2026","intvolume":"        22","status":"public"},{"doi":"10.1145/3769423","acknowledgement":"We thank the ACM TOCS Editors and the reviewers for their help in improving the manuscript.

Unfortunately, the BFT consensus algorithms that are the backbone of most of these blockchains scale poorly and offer limited throughput. In fact, many state-of-the-art BFT consensus algorithms require a single leader process to receive and validate votes from a quorum of processes and then broadcast the result, which is inherently non-scalable. Recent approaches avoid this bottleneck by using dissemination/aggregation trees to propagate values and collect and validate votes. However, the use of trees increases the round latency, which limits the throughput for deeper trees. In this paper we propose Kauri, a BFT communication abstraction that sustains high throughput as the system size grows by leveraging a novel pipelining technique to perform scalable dissemination and aggregation on trees. Furthermore, when the number of faults is moderate (arguably the most common case in practice), our construction is able to recover from faults in an optimal number of reconfiguration steps. We implemented and experimentally evaluated Kauri with up to 800 processes. Our results show that Kauri outperforms the throughput of state-of-the-art permissioned blockchain protocols, by up to 58x without compromising latency. Interestingly, in some cases, the parallelization provided by Kauri can also decrease the latency."}],"issue":"2"},{"publication":"Inventiones Mathematicae","date_updated":"2026-07-23T10:58:59Z","researchdata_availability":"no","month":"04","article_type":"original","has_accepted_license":"1","language":[{"iso":"eng"}],"_id":"14278","publication_status":"published","day":"01","department":[{"_id":"GradSch"},{"_id":"VaKa"}],"publication_identifier":{"eissn":["1432-1297"],"issn":["0020-9910"]},"tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"oa_version":"Published Version","type":"journal_article","citation":{"ista":"Koval I. 2026.

In this article, we consider a stronger notion of integrability, namely, integrability close to the boundary, and prove a local version of this conjecture: a small perturbation of almost every ellipse that preserves integrability near the boundary, is itself an ellipse. We apply this result to study local spectral uniqueness of ellipses using the connection between the wave trace of the Laplacian and the dynamics near the boundary and establish local uniqueness for almost all of them.","lang":"eng"}],"year":"2026","corr_author":"1","page":"221-298","PlanS_conform":"1","intvolume":"       244","project":[{"_id":"9B8B92DE-BA93-11EA-9121-9846C619BF3A","name":"Spectral rigidity and integrability for billiards and geodesic flows","grant_number":"885707","call_identifier":"H2020"}],"status":"public","mathsc":["37C83","35J05","37J70","74J25"],"date_created":"2023-09-06T08:35:43Z","das_tickbox":"0","file_date_updated":"2026-07-23T10:55:24Z","article_processing_charge":"Yes (via OA deal)","ddc":["510"],"ec_funded":1,"date_published":"2026-04-01T00:00:00Z","supplementarymaterial":"yes","scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"file_name":"2026_InventionesMath_Koval.pdf","creator":"dernst","date_updated":"2026-07-23T10:55:24Z","date_created":"2026-07-23T10:55:24Z","file_size":2256345,"content_type":"application/pdf","file_id":"22394","checksum":"487fa9113e1bbf32a6c70e6d1e8f63bc","success":1,"relation":"main_file","access_level":"open_access"}],"publisher":"Springer Nature","arxiv":1,"external_id":{"arxiv":["2111.12171"]},"oa":1,"quality_controlled":"1"},{"OA_place":"publisher","author":[{"first_name":"Sebastian","full_name":"Haidarliu, Sebastian","last_name":"Haidarliu"},{"full_name":"Nelinger, Guy","first_name":"Guy","last_name":"Nelinger"},{"full_name":"Gantar, Luka","first_name":"Luka","last_name":"Gantar","id":"ed7c4564-13aa-11f0-9846-960f9afb2ddb"},{"full_name":"Ahissar, Ehud","first_name":"Ehud","last_name":"Ahissar"},{"first_name":"Inbar","full_name":"Saraf‐Sinik, Inbar","last_name":"Saraf‐Sinik"}],"OA_type":"hybrid","acknowledgement":"The authors wish to express their gratitude to Prof. Menahem Segal and Dr. Yonatan Katz for their helpful comments and discussions.

Yet, while indicating that reafference originates from the mechanoreceptors, the mechanistic underpinnings of the whisking phase encoding within the follicle remain unclear. Here we present anatomical, histological, and biomechanical evidence for the presence of a distinctive elastic segment (ES) within the basal part of the whisker shaft inside the follicle. This ES, composed of immature keratin, is capable of both bending and twisting. Forces generated by whisker movement deform this segment, causing whisker shaft deflections that can stimulate specific mechanoreceptor subsets within the follicle at different phases of the whisking cycle. This mechanism appears to operate during both free‐air whisking and object contact. We propose that the ES enables torsion‐based mechanoreceptor activation, allowing encoding of the whisking phase.","lang":"eng"}],"year":"2026"},{"year":"2026","abstract":[{"text":"Let A be an abelian variety defined over a number field K, E/K be an elliptic curve, and ϕ : A → Em be an isogeny defined over K.

In this study, FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S) reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells, and pouch cells reveal that HEANS significantly enhance LSB performance, achieving initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent cycling stability over 1000 cycles at 3Cand maintain high-rate performance up to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density functional theory calculations demonstrate that amorphous HEANS provide more active sites, better ionic conductivity and stronger chemical interactions with lithium polysulfides (LiPS). These properties effectively suppress the shuttle effect, promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy barrier. Overall, this study highlights the superior catalytic properties of amorphous 2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion.","lang":"eng"}],"acknowledgement":"The authors acknowledge support from the 2BoSS project of the ERA-MIN3 program with the Spanish grant number PCI2022-132985/AEI/10.13039/50110001103, and funding from Generalitat de Catalunya 2021SGR01581 and European Union NextGenerationEU/PRTR.

It plays a central role in the weather and climate of the Tropics, where, to first order, the heating of the atmosphere by convection is in balance with the cooling of the atmosphere by the emission of radiation to outer space. In this study, we use a cloud-resolving model in radiative–convective equilibrium with an imposed constant rate of radiative cooling and study the response of moist convection to varying this rate of radiative cooling. In particular, we study two types of simulation: varying air temperature (VAT) simulations, where the air temperature is allowed to adjust to the imposed radiative cooling, and constant air temperature (CAT) simulations, where the surface temperature is tuned to ensure that the atmospheric temperature profile in the domain is constant. We recover the previously known result that, in response to increasing radiative cooling, the area of convection expands rapidly, while the intensity of convection does not change. We find that this response is explained by the increased boundary-layer variability in simulations with greater radiative cooling, which compensates for the decreasing temperature by adding a larger initial velocity close to the cloud base. We also propose a fundamental scaling of the non-dimensional cumulus mass flux in moist convection, which is robust across models of different complexity. We aim to bridge the gap between highly idealised prototypes of moist convection, such as the “Rainy–Bénard convection” introduced by Vallis et al., and comprehensive cloud-resolving models."}],"issue":"775","project":[{"_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","name":"IST-BRIDGE: International postdoctoral program","grant_number":"101034413","call_identifier":"H2020"},{"_id":"629205d8-2b32-11ec-9570-e1356ff73576","name":"Organization of CLoUdS, and implications of Tropical  cyclones and for the Energetics of the tropics, in current and waRming climate","call_identifier":"H2020","grant_number":"805041"}],"status":"public","corr_author":"1","PlanS_conform":"1","intvolume":"       152"},{"oa_version":"Preprint","type":"journal_article","title":"Chromatic alpha complexes","citation":{"short":"S.

First, the broadcast problem: given n agents, each agent is tasked to forward a (unique) message to every other agent. Agents collaborate and can copy and forward all messages they have received up until that point. Broadcast is achieved when one agent has successfully broadcast its message to everyone else. We studied the case where the communication network is controlled by an adversary, under the condition that the graph is rooted in every round of communication. We show that the adversary can delay broadcast for at most  l\r\n(1 + √\r\n2)n\r\nm\r\n rounds, improving on the $O(n\\log\\log n)$ previous upper bound~\\cite{fugger2020radius}, and asymptotically matching the $\\sim 1.5n$ lower bound~\\cite{schwarz2017linear}.\r\n\r\nWe then looked at the stochastic version of the problem: here, the adversary -- parametrized by $k$ where $k=0$ signifies that the adversary has no control,  and $k=n$ that the adversary has full control -- can choose parts of the graph, and the graph is then completed stochastically. Here, we are able to look at a stronger version of broadcast: instead of having $n$ messages trying to be broadcast in parallel, we can assume that only one message needs to be broadcasted. We show the bound $\\Theta(k+\\log n)$.\r\n\r\nThen, we looked at undecided states dynamics in population protocols: given a population of $n$ agents, where each initially holds an opinion among $k$ different ones. In each round, two agents are chosen uniformly at random, and can interact. If they have different opinions, they forget their opinions and become undecided. If one of them is undecided while the other has an opinion, they undecided agent copies they opinion of the decided one. The question is then, how many interactions does it take for the whole population to share the same opinion? We show a $\\Omega(kn\\log \\frac {\\sqrt n} {k \\log n})$ lower bound  for any $k = o\\left(\\frac {\\sqrt n}{\\log n}\\right)$.\r\nThis is tight for any $ k \\le n^{\\frac 1 2 - \\epsilon}$, where $\\epsilon >0$ can be any small constant, matching the known $O(kn\\log n)$ upper bound for $k = O\\left(\\frac {\\sqrt n} {\\log ^2 n}\\right)$~\\cite{DBLP:conf/podc/AmirABBHKL23}.\r\n\r\nFinally, in dynamic algorithms, we study the minimum cut problem: we are given a graph, whose vertex set we want to partition into two subsets such that the number of edges crossing from one subset to the other is minimized. Then, the graph can be updated via edge insertions or deletions, and we must update the solution without recomputing everything from scratch. We present an exact fully-dynamic minimum cut algorithm that runs in $n^{o(1)}$ deterministic update time when the minimum cut size is at most $2^{\\Theta(\\log^{3/4-c}n)}$ for any $c>0$, improving on the previous algorithm~\\cite{DBLP:conf/soda/JinST24} whose minimum cut size limit is $(\\log n)^{o(1)}$. Using sparsification and randomization techniques, we are able to extend this to all values of the minimum cut in weighted graphs, at the cost of a $(1+o(1))$-approximation ratio.","lang":"eng"}],"alternative_title":["ISTA Thesis"],"acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (MoDynStruct, No. 101019564)\r\n\"The Design and Evaluation of Modern Fully Dynamic Data Structures\" , from the\r\nAustrian Science Fund (FWF) grant DOI 10.55776/I5982 \"Static and Dynamic Hierarchical\r\nGraph Decompositions\", and from the Austrian Science Fund (FWF) and netIDEE SCIENCE\r\nproject P 33775-N, \"Fast Algorithms for a Reactive Network Layer\".\r\n","doi":"10.15479/AT-ISTA-22281","OA_place":"publisher","author":[{"last_name":"El-Hayek","first_name":"Antoine","full_name":"El-Hayek, Antoine","id":"888a098e-fcac-11ee-aff7-d347be57b725","orcid":"0000-0003-4268-7368"}],"title":"Handling updates and failures: Dynamic graph algorithms and distributed computing on dynamic networks","citation":{"apa":"El-Hayek, A.
