end of reionization","abstract":[{"lang":"eng","text":"Finding the first generation of (Population III or Pop III) stars is one of the most ambitious and exciting challenges of astrophysics. JWST opened concrete prospects for their detection during the Epoch of Reionization, where increasing evidence suggests that residual Pop III formation may persist, even within pristine pockets of high-mass halos, due to inhomogeneous enrichment. However, the identification of Pop III stars within globally enriched environments will be challenging. We investigate the detectability of a subdominant Pop III component in/around massive (M⋆ ≳ 10^9 M⊙) galaxies at z ≈ 6.5–9 from the dustyGadget cosmological simulation suite, and the confusion arising from second-generation (Pop II) stars in their surroundings. We find that young (≲1 Myr), massive (MIII ∼ 6 × 10^5 M⊙) Pop III clusters forming within these galaxy environments are responsible for strong HeII1640 line emission (LHeII1640 ≳ 10^41 erg ^s−1), which would be detectable with ≈10(50) hr of medium-resolution observations with NIRSpec/IFU at z ≈ 6(10). These bright luminosities cannot be produced by standard Pop II populations alone. On the other hand, the dominant Pop II component within massive “hybrid” Pop III hosts powers strong metal line emission (L[OIII]5007 ≳ 10^42 erg s^−1), indicating that the detection of metal lines alone cannot exclude the presence of Pop IIIs in high-z galaxy environments. We further discuss candidate selection strategies based on Lyα, Hα, and Hβ emission, and how spatially resolved observations may enable the detection of isolated, pristine pockets in the outskirts of massive halos."}],"file_date_updated":"2026-07-20T13:05:27Z","date_updated":"2026-07-20T13:07:08Z","month":"07","oa_version":"Published Version","intvolume":"      1005","issue":"2","year":"2026","oa":1,"article_processing_charge":"Yes","ddc":["520"],"author":[{"first_name":"Alessandra","full_name":"Venditti, Alessandra","last_name":"Venditti"},{"last_name":"Graziani","first_name":"Luca","full_name":"Graziani, Luca"},{"last_name":"Schneider","first_name":"Raffaella","full_name":"Schneider, Raffaella"},{"full_name":"Bromm, Volker","first_name":"Volker","last_name":"Bromm"},{"last_name":"Muñoz","first_name":"Julian B.","full_name":"Muñoz, Julian B."},{"id":"2d002343-372f-11ef-98ec-a164d20427cb","first_name":"Claudia","full_name":"Di Cesare, Claudia","last_name":"Di Cesare"},{"first_name":"Rosa","full_name":"Valiante, Rosa","last_name":"Valiante"},{"last_name":"Calabrò","first_name":"Antonello","full_name":"Calabrò, Antonello"},{"first_name":"Roberto","full_name":"Maiolino, Roberto","last_name":"Maiolino"},{"first_name":"Steven L.","full_name":"Finkelstein, Steven L.","last_name":"Finkelstein"},{"last_name":"Parente","full_name":"Parente, Massimiliano","first_name":"Massimiliano"},{"last_name":"Saggini","first_name":"Matteo","full_name":"Saggini, Matteo"},{"first_name":"John","full_name":"Chisholm, John","last_name":"Chisholm"}],"publication_status":"published","article_type":"original","volume":1005,"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"quality_controlled":"1","OA_place":"publisher","arxiv":1,"PlanS_conform":"1","OA_type":"gold","article_number":"226","dataavailabilitystatement":"Software: dustyGadget (L.

Here we present a blind and unbiased search for and characterisation of galaxy overdensities during the reionisation epoch at redshifts z ∼ 5.5 − 7 based on rest-frame optical JWST/NIRCam grism spectroscopy of the Abell 2744 lensing field as part of the JWST All the Little Things (ALT) survey. Using a physically motivated, cosmological inference friends-of-friends (FoF) algorithm, we identified six galaxy overdensities, including five robust systems at z = 5.66–6.77. They are all characterised by total halo masses of Mhalo ≳ 1011 M⊙, inferred from a range of proxies. We find that the galaxy members in these overdense environments are on average less massive though equally metal-rich, and generally comprised of younger stellar populations, as indicated by their bluer spectral slopes and less prominent Balmer breaks compared to field galaxies at similar redshifts. Further, we use this novel rest-frame optical selection of galaxy proto-clusters to infer the fraction and 3D distribution of strong Lyman-α emitters (LAEs) and damped Lyman-α absorbers (DLAs) in the overdensity environments. We find that two out of the six galaxy overdensities have excess H I absorption compared to the field average, while the other four are consistent within their large scatter in density. These results present the first direct observational constraints on the tomography of the dense, neutral gas reservoirs in large-scale galaxy overdensities at z > 5 and highlight the limitations of pre-JWST searches for reionisation-era galaxy overdensities relying on the detection of strong LAEs alone."}],"file_date_updated":"2026-07-20T13:41:19Z","date_updated":"2026-07-20T13:42:20Z","supplementarymaterial":"yes","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"day":"01","date_published":"2026-06-01T00:00:00Z","language":[{"iso":"eng"}],"fulldoi":"https://doi.org/10.1051/0004-6361/202659436","file":[{"creator":"dernst","success":1,"relation":"main_file","date_created":"2026-07-20T13:41:19Z","checksum":"0a63db666cfac8e4e6271b75419a26f2","date_updated":"2026-07-20T13:41:19Z","file_size":6156048,"content_type":"application/pdf","file_name":"2026_AstronomyAstrophysics_Terp.pdf","file_id":"22378","access_level":"open_access"}],"volume":710,"publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"OA_place":"publisher","quality_controlled":"1","OA_type":"diamond","PlanS_conform":"1","article_number":"A290","dataavailabilitystatement":"The specific observations analysed in this work can be accessed via https://doi.org/10.5281/zenodo.13871850","acknowledgement":"We would like to thank the anonymous referee for their positive and constructive report and all the observers world-wide for their substantial effort in securing all the public JWST data that were essential for this work.

But how this fundamental asymmetry is established remains unclear1. Neuronal polarization has been thought to rely primarily on growth cones that sense external cues2. Here we show that growth cones alone do not direct this process and that the soma acts as a central organizer of neuronal polarization. Using live imaging and genetic loss-of-function approaches in vivo, combined with optogenetic control and local cytoskeletal perturbations in cultured neurons, we uncover a soma-initiated oscillatory program that primes axon selection. Periodic actin branching that depends on the actin-related protein 2/3 (ARP2/3) complex at the soma remodels a global actomyosin network, thereby generating an actin wave that retracts neurites before propagating into a single neurite tip. Exposure to this wave relaxes local actomyosin contractility, which drives a transient microtubule-based protrusion and biases this neurite towards axon fate. As the cell exits this oscillatory stage, this neurite can overcome global inhibition and extend independently of ARP2/3, whereas actomyosin activity suppresses axon formation in the remaining neurites so that they subsequently become dendrites. This soma-driven mechanism ensures the emergence of a single axon independent of environmental cues and underpins the unidirectional information flow in neuronal circuits.","lang":"eng"}],"title":"An intrinsic cytoskeletal oscillator establishes neuronal polarity","date_updated":"2026-07-20T14:18:10Z","pmid":1},{"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"doi_confirm":"1","file":[{"access_level":"open_access","file_id":"22337","file_name":"2026_Li_Yunzhe_Thesis.pdf","content_type":"application/pdf","file_size":1260717,"date_updated":"2026-07-14T10:48:45Z","checksum":"8201cb5a427656a41828ecde8a85c04b","relation":"main_file","date_created":"2026-07-14T10:48:45Z","creator":"yli"},{"date_created":"2026-07-14T11:07:18Z","relation":"source_file","creator":"yli","file_size":418752,"date_updated":"2026-07-20T14:00:33Z","checksum":"19ee8461ed77f5b7980fc9461f778b6f","file_name":"2026_Li_Yunzhe_Thesis.zip","content_type":"application/x-zip-compressed","access_level":"closed","file_id":"22339"}],"fulldoi":"https://doi.org/10.15479/AT-ISTA-22255","language":[{"iso":"eng"}],"day":"11","date_published":"2026-07-11T00:00:00Z","doi":"10.15479/AT-ISTA-22255","publisher":"Institute of Science and Technology Austria","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","type":"dissertation","project":[{"grant_number":"885707","call_identifier":"H2020","name":"Spectral rigidity and integrability for billiards and geodesic flows","_id":"9B8B92DE-BA93-11EA-9121-9846C619BF3A"}],"_id":"22255","status":"public","page":"131","date_updated":"2026-07-20T14:58:23Z","file_date_updated":"2026-07-20T14:00:33Z","abstract":[{"lang":"eng","text":"This thesis studies spectral rigidity and nonrigidity phenomena in dynamical systems. The central question is whether a dynamical system can be determined, up to a natural conjugacy, from its spectrum. We consider three related spectra: the length spectrum, the action spectrum, and the Lyapunov spectrum.\r\n\r\nThe first part of the thesis concerns Liouville metrics on the two-dimensional torus. It is a long-standing folklore conjecture that Liouville metrics are the only integrable metrics on the torus. We prove a length-spectral rigidity result for linear conformal deformations of Liouville metrics by exploiting the dynamical properties of the rational tori -- analogues of the resonant convex caustics in billiards. We also establish a complementary classification result showing that marked-length-isospectral Liouville metrics are characterized by rearrangements of the one-dimensional functions appearing in their conformal factors, generalizing a theorem of Abbondandolo-Mazzucchelli. In particular, the second result gives nonrigidity examples within the class of Liouville metrics.\r\n\r\nThe second part of the thesis studies the standard map from the viewpoint of action and Lyapunov spectra. We construct nontrivial deformations of the standard map which preserve the symplectic actions (respectively, the Lyapunov exponents) of infinitely many periodic orbits accumulating on an invariant curve. The proof combines a resonant normal form construction with Picard iteration schemes to obtain a sequence of periodic orbits accumulating on an invariant curve with a Liouville rotation number. Within the resonant normal forms we capture the dependence of these periodic orbits on the resonant Fourier coefficients of the dynamics on the invariant curve and, using the contraction mapping principle, obtain a suitable deformation achieving the prescribed spectral data associated with this sequence of orbits. The result can be viewed as a symplectic twist-map analogue of a length-spectral nonrigidity phenomenon for Riemannian manifolds and convex billiards, and it motivates the existence problem for similar 'partially length-isospectral' deformations of strictly convex billiard tables.\r\n"}],"title":"Spectral rigidity and nonrigidity of dynamical systems","degree_awarded":"PhD","article_processing_charge":"No","year":"2026","oa":1,"oa_version":"Published Version","month":"07","publication_status":"published","author":[{"id":"41cb05d3-f128-11eb-9611-e4e2b3cfba31","full_name":"Li, Yunzhe","first_name":"Yunzhe","last_name":"Li"}],"ddc":["515"],"supervisor":[{"full_name":"Kaloshin, Vadim","orcid":"0000-0002-6051-2628","first_name":"Vadim","id":"FE553552-CDE8-11E9-B324-C0EBE5697425","last_name":"Kaloshin"}],"acknowledgement":"The financial support of the ERC grant SPERIG #885707 is gratefully acknowledged.\r\n","OA_place":"publisher","ec_funded":1,"publication_identifier":{"issn":["2663-337X"]},"related_material":{"record":[{"id":"22340","status":"public","relation":"part_of_dissertation"},{"id":"22341","relation":"part_of_dissertation","status":"public"}]},"alternative_title":["ISTA Thesis"],"acknowledged_ssus":[{"_id":"E-Lib"},{"_id":"CampIT"}],"has_accepted_license":"1","corr_author":"1","citation":{"chicago":"Li, Yunzhe. “Spectral Rigidity and Nonrigidity of Dynamical Systems.” Institute of Science and Technology Austria, 2026. <a href=\"https://doi.org/10.15479/AT-ISTA-22255\">https://doi.org/10.15479/AT-ISTA-22255</a>.","ieee":"Y.

Spatial polarization of organelles within cells, including endo-lysosomes, is a prerequisite of migration.

Here we show that signaling molecules generated by endo-lysosome-localized kinases regulate velocity of amoeboid migration. Specifically, imaging of T cells identifies accumulation of endo-lysosomes decorated with the lipid kinases VPS34–PIKfyve at the uropod of polarized cells. Activity of VPS34 and PIKfyve regulates speed, but not directedness, of migrating T cells. Mechanistically, PI(3,5)P2 generated by the sequential action of VPS34 and PIKfyve, mediates Ca2+ efflux from lysosomes via the mucolipin TRP cation channel 1 (TRPML1), thus controlling activity of myosin IIA and hence the generation of propulsive force through retrograde actin flow. The VPS34–PIKfyve kinases also regulate velocity of myeloid cells, as well as of the amoeba Dictyostelium discoideum – establishing the axis as an evolutionarily conserved speed control system of amoeboid cell migration."}],"title":"A conserved VPS34-PIKfyve-TRPML1-myosin II axis regulates the speed of amoeboid cell migration","date_updated":"2026-07-20T14:28:59Z","pmid":1,"oa_version":"Published Version","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s44319-026-00861-x"}],"month":"07","year":"2026","oa":1,"article_processing_charge":"Yes (via OA deal)","author":[{"last_name":"Dehio","full_name":"Dehio, Philippe G","first_name":"Philippe G","id":"b769738e-a003-11ee-b1b8-9030316e0d59"},{"first_name":"Céline","full_name":"Michard, Céline","last_name":"Michard"},{"last_name":"Yam-Puc","first_name":"Juan Carlos","full_name":"Yam-Puc, Juan Carlos"},{"first_name":"Adrià Arnau","full_name":"Martí I Líndez, Adrià Arnau","last_name":"Martí I Líndez"},{"full_name":"Jandke, Anett","first_name":"Anett","last_name":"Jandke"},{"full_name":"Unterstab, Gunhild","first_name":"Gunhild","last_name":"Unterstab"},{"first_name":"Lucien","full_name":"Fabre, Lucien","last_name":"Fabre"},{"last_name":"Sauteur","first_name":"Loïc","full_name":"Sauteur, Loïc"},{"first_name":"Marc","full_name":"Artinger, Marc","last_name":"Artinger"},{"first_name":"Daniel F.","full_name":"Legler, Daniel F.","last_name":"Legler"},{"last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","first_name":"Michael K","orcid":"0000-0002-6620-9179","full_name":"Sixt, Michael K"},{"last_name":"Schaefer","first_name":"Thorsten","full_name":"Schaefer, Thorsten"},{"full_name":"Wymann, Matthias P.","first_name":"Matthias P.","last_name":"Wymann"},{"last_name":"Okkenhaug","first_name":"Klaus","full_name":"Okkenhaug, Klaus"},{"last_name":"Soldati","first_name":"Thierry","full_name":"Soldati, Thierry"},{"last_name":"Mehling","full_name":"Mehling, Matthias","orcid":"0000-0001-8599-1226","first_name":"Matthias","id":"3C23B994-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Hess","full_name":"Hess, Christoph","first_name":"Christoph"}],"article_type":"original","publication_status":"epub_ahead","quality_controlled":"1","OA_place":"publisher","OA_type":"gold","publication_identifier":{"eissn":["1469-3178"]},"acknowledgement":"We thank the microscopy core facility of the Department of Biomedicine at the University and University Hospital of Basel for their technical support.

In this study, we employed forward genetic screening to identify Arabidopsis mutants with defective hypocotyl gravitropism and isolated the short and agravitropic hypocotyl in dark1 (sad1) mutant, which carries a point mutation (G110E) in the SAC1 gene encoding a phosphoinositide phosphatase. Deficiency of SAC1 disrupted gravity-induced polar localization of PIN3 in endodermal cells, impairing auxin redistribution and leading to hypocotyl gravitropism defects. Subcellular localization analysis revealed that SAC1 is partially localized to the PVC/tonoplast and participates in late endosomal trafficking. The sac1 mutation leads to abnormal vacuolar morphology, which is associated with defects in amyloplast sedimentation during the gravitropic response in Arabidopsis shoots. We further revealed that SAC1 interacts with GRV2, a key regulator of the late endocytic pathway, and that both proteins cooperatively regulate shoot gravitropism. In summary, this study identified SAC1 as a regulator of shoot gravitropism, revealing its important role in modulating vacuolar homeostasis, amyloplast sedimentation, PIN3 trafficking, and auxin distribution. These findings provide insights into the molecular mechanisms linking membrane transport to environmental adaptation in plants."}],"title":"Regulation of shoot gravitropism and branching angle by the GRV2-SAC1 axis in Arabidopsis","doi":"10.1111/tpj.71042","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Wiley","status":"public","_id":"22366","type":"journal_article","language":[{"iso":"eng"}],"fulldoi":"https://doi.org/10.1111/tpj.71042","external_id":{"pmid":["42438075"]},"day":"01","date_published":"2026-07-01T00:00:00Z","keyword":["auxin","SAC1","GRV2","PIN3","vacuole","gravitropism","Arabidopsis"],"supplementarymaterial":"yes"},{"month":"07","oa_version":"Published Version","article_processing_charge":"No","year":"2026","oa":1,"ddc":["000"],"publication_status":"published","author":[{"last_name":"D'Archivio","first_name":"Niccolò","full_name":"D'Archivio, Niccolò"},{"last_name":"Almahmoud","first_name":"Hind","full_name":"Almahmoud, Hind"},{"full_name":"Natale, Emanuele","first_name":"Emanuele","last_name":"Natale"},{"id":"68748c44-84d5-11f1-b4f6-ca083374e553","first_name":"Frederik","full_name":"Mallmann-Trenn, Frederik","last_name":"Mallmann-Trenn"}],"publication_identifier":{"isbn":["9798400725128"]},"OA_type":"gold","quality_controlled":"1","OA_place":"publisher","acknowledgement":"This work has been supported by the AID INRIA-DGA project\r\nn°2023000872 “BioSwarm”, the French government National Research Agency (ANR) through the UCA JEDI (ANR-15-IDEX-01),\r\nthe EUR DS4H (ANR-17-EURE-004) and the 3IA Cote d’Azur Investments ANR-23-IACL-0001, and EPSRC grant EP/W005573/1","scopus_import":"1","department":[{"_id":"MoHe"}],"das_tickbox":"0","date_created":"2026-07-19T22:01:47Z","researchdata_availability":"no","publication":"Proceedings of the Annual ACM Symposium on Principles of Distributed Computing","corr_author":"1","citation":{"ista":"D’Archivio N, Almahmoud H, Natale E, Mallmann-Trenn F. 2026.

Such\r\ndynamics often converge to consensus on a single fixation value 𝑋ˆ.\r\nThis paper asks how to control the distribution of 𝑋ˆ as a randomised\r\nchoice among the initial opinions by designing suitable simple\r\ndynamics. Writing the sorted initial values as 𝑥(1) ≤ · · · ≤ 𝑥(𝑛)\r\n,\r\nwe design two protocols that realise natural target laws over order\r\nstatistics.\r\nFirst, for a parameter 𝑝 ∈ (0, 1), our geometric protocol biases\r\ntoward larger opinions and satisfies P\r\n\r\n𝑋ˆ = 𝑥(𝑘)\r\n\r\n∝ 𝑝\r\n𝑛−𝑘\r\n, for\r\n𝑘 = 1, . . . , 𝑛. Equivalently, P\r\n\r\n𝑋ˆ = 𝑥(𝑘)\r\n\r\n= (1 − 𝑝)𝑝\r\n𝑛−𝑘\r\n/(1 − 𝑝\r\n𝑛\r\n).\r\nSecond, our binomial protocol assigns a shifted binomial law to the\r\nranks in ascending order: if 𝐾 −1 ∼ Bin(𝑛−1, 1−𝑝), then 𝑋ˆ = 𝑥(𝐾)\r\n,\r\ni.e., P\r\n\r\n𝑋ˆ = 𝑥(𝑘)\r\n\r\n=\r\n𝑛−1\r\n𝑘−1\r\n\u0001\r\n𝑝\r\n𝑛−𝑘\r\n(1 − 𝑝)\r\n𝑘−1\r\n, for 𝑘 = 1, . . . , 𝑛.\r\nApplications of this include computing the Top-𝑘 values for\r\nsmall 𝑘 on general interaction graphs. A central contribution of\r\nthis work is that, in contrast to most population protocols, we can\r\ncharacterise the fixation distribution in closed form. This is enabled\r\nby a novel analysis technique, which also yields applications: we\r\nderive new results for the Median protocol that extend the state of\r\nthe art.","lang":"eng"}],"date_updated":"2026-07-21T07:34:49Z","page":"425-436"},{"file":[{"file_name":"2026_ACMPODC_Cooper.pdf","content_type":"application/pdf","access_level":"open_access","file_id":"22380","date_created":"2026-07-21T07:51:58Z","relation":"main_file","success":1,"creator":"dernst","file_size":709077,"checksum":"9ada61feba1e93fd72867a5ba4ee8bb8","date_updated":"2026-07-21T07:51:58Z"}],"fulldoi":"https://doi.org/10.1145/3796701.3815920","language":[{"iso":"eng"}],"external_id":{"arxiv":["2603.02636"]},"day":"01","date_published":"2026-07-01T00:00:00Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"supplementarymaterial":"no","keyword":["consensus dynamics","undecided state dynamics","gossip model","population protocol model"],"page":"77-87","date_updated":"2026-07-21T07:54:01Z","file_date_updated":"2026-07-21T07:51:58Z","conference":{"end_date":"2026-07-10","start_date":"2026-07-06","location":"Egham, United Kingdom","name":"PODC: Symposium on Principles of Distributed Computing"},"abstract":[{"lang":"eng","text":"We study the Undecided-State Dynamics (USD), a fundamental consensus process in which each vertex holds one of k decided opinions or the undecided state.

We introduce an alternative experimental probe, capturing microwave radiation across all three regimes, using a two-dimensional array of superconductor-semiconductor hybrid Josephson junctions as a model system. Our approach allows  calibration of the sample’s circuit parameters and provides isolation from measurement back-action effects. We measure the radiation temperature of the anomalous metal and find that it is hotter than both the quantum-critical and insulating regimes. We further show that the anomalous metallic regime is more susceptible to additional heating than other regimes, explaining its emergence in otherwise thermalized systems. Turning to the quantum-critical regime, we discover nonlinear scaling of radiative noise with applied bias, consistent with theoretical predictions of universal nonequilibrium behavior at quantum-critical points."}],"file_date_updated":"2026-07-16T09:39:37Z","title":"Microwave radiometry of a quantum-critical hybrid Josephson array","date_updated":"2026-07-21T12:01:49Z","supplementarymaterial":"no","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"day":"10","date_published":"2026-07-10T00:00:00Z","language":[{"iso":"eng"}],"file":[{"date_updated":"2026-07-16T09:39:37Z","checksum":"d872ca35d9d2c7821642fda520be2c15","file_size":2750867,"success":1,"creator":"dernst","relation":"main_file","date_created":"2026-07-16T09:39:37Z","file_id":"22350","access_level":"open_access","content_type":"application/pdf","file_name":"2026_PhysicalReviewApplied_Leonard.pdf"}],"fulldoi":"https://doi.org/10.1103/75bl-mm3b","external_id":{"arxiv":["2409.09835"]}},{"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"supplementarymaterial":"yes","file":[{"file_id":"22348","access_level":"open_access","file_name":"2026_ACMFACCT_Cano.pdf","content_type":"application/pdf","checksum":"21e648ea3b529f0df7545ad4b31b0ef4","date_updated":"2026-07-16T09:23:15Z","file_size":3129128,"creator":"dernst","success":1,"date_created":"2026-07-16T09:23:15Z","relation":"main_file"}],"fulldoi":"https://doi.org/10.1145/3805689.3806807","language":[{"iso":"eng"}],"external_id":{"arxiv":["2605.24926"]},"date_published":"2026-07-01T00:00:00Z","day":"01","doi":"10.1145/3805689.3806807","publisher":"Association for Computing Machinery","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"conference","project":[{"grant_number":"101020093","_id":"62781420-2b32-11ec-9570-8d9b63373d4d","name":"Vigilant Algorithmic Monitoring of Software","call_identifier":"H2020"}],"_id":"22321","status":"public","date_updated":"2026-07-22T06:15:56Z","page":"4243 - 4275","file_date_updated":"2026-07-16T09:23:15Z","conference":{"end_date":"2026-06-28","start_date":"2026-06-25","location":"Montreal, Canada","name":"FAccT: Conference on Fairness, Accountability and Transparency"},"abstract":[{"lang":"eng","text":"Runtime fairness is not a one-time constraint but a dynamic property evaluated over a sequence of decisions. To ensure fairness at runtime, it is necessary to account for past decisions, information neglected by conventional, static classifiers. Traditional fairness shields enforce runtime fairness abruptly, by intervening deterministically whenever a sequence of decisions violates the target for a running fairness measure. This motivates our main conceptual contribution: energy shields. An energy shield is a novel, lightweight, adaptive controller that monitors a sequence of decisions and intervenes probabilistically to ensure runtime fairness smoothly, by utilizing physics-inspired energy functions to nudge the sequence toward fairness: the more unfair the decisions, the stronger the nudging force becomes. This makes energy shields the first fairness shields to provide both short-term safety and long-term liveness guarantees. Safety ensures that the running fairness measure stays within a running target interval with high probability, and liveness ensures that the limit of the fairness measure lies within the limit target interval. Intuitively, the short-term specifies the tolerated fairness values and the long-term specifies the desired fairness values. We also provide a synthesis procedure for constructing the least intrusive energy shield for a given target specification, and demonstrate its efficiency experimentally. We evaluate our energy shields against existing fairness shields through the lens of short- and long-term fairness."}],"title":"Energy shields for fairness","article_processing_charge":"Yes","oa":1,"year":"2026","oa_version":"Published Version","month":"07","publication_status":"published","author":[{"last_name":"Cano Cordoba","first_name":"Filip","orcid":"0000-0002-0783-904X","full_name":"Cano Cordoba, Filip","id":"708cad98-e86a-11ef-8098-bdae2d7c6af1"},{"last_name":"Henzinger","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2985-7724","full_name":"Henzinger, Thomas A","first_name":"Thomas A"},{"id":"8121a2d0-dc85-11ea-9058-af578f3b4515","first_name":"Konstantin","orcid":"0000-0001-8974-2542","full_name":"Kueffner, Konstantin","last_name":"Kueffner"}],"ddc":["000"],"acknowledgement":"This work has been supported by the European Research Council under Grant No.: ERC-2020-AdG 101020093.","OA_type":"gold","arxiv":1,"quality_controlled":"1","OA_place":"publisher","ec_funded":1,"has_accepted_license":"1","corr_author":"1","citation":{"ieee":"F.

This study examined the multiscale processes contributing to this extreme precipitation event, focusing on intraseasonal oscillations, synoptic-scale circulations, and mesoscale cloud/precipitation systems. A quasi-biweekly intraseasonal oscillation dominated over South Asia during the event, featuring a monsoon low-pressure system over the Indian Peninsula and an anticyclone to its east, both propagating westward. The pressure gradient between them sustained strong southerly moisture transport toward the Himalayas, establishing a persistently humid environment and orographic lift along the southern slopes. In contrast to reports of previous extreme precipitation events in Nepal, the atmospheric circulation responsible for the 2024 event was primarily of tropical origin, with minimal influence from the midlatitudes. Characteristic mesoscale cloud/precipitation systems also developed around the Himalayas. The highest daily precipitation during the event was recorded on 27 September; stratiform systems with relatively modest storm top heights developed over the southern slopes, generating surface precipitation rates of > 100 mm h− 1 through warm-rain processes. Rain gauges across the glacierized basin (3500–5000 m asl) recorded exceptionally high daily and hourly precipitation rates, highlighting the extension of intense rainfall to unusually high elevations."}],"title":"Multiscale aspects of an extreme precipitation event over Nepal in September 2024","date_updated":"2026-07-22T06:14:16Z","supplementarymaterial":"yes","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"day":"04","date_published":"2026-06-04T00:00:00Z","fulldoi":"https://doi.org/10.1007/s44393-026-00024-0","file":[{"checksum":"19a217b038756abf44bc49939a01e33c","date_updated":"2026-06-22T07:21:04Z","file_size":13308662,"success":1,"creator":"dernst","relation":"main_file","date_created":"2026-06-22T07:21:04Z","file_id":"22109","access_level":"open_access","content_type":"application/pdf","file_name":"2026_SOLA_Fujinami.pdf"}],"language":[{"iso":"eng"}],"OA_type":"gold","PlanS_conform":"1","quality_controlled":"1","OA_place":"publisher","publication_identifier":{"eissn":["1349-6476"]},"volume":22,"dataavailabilitystatement":"Daily rainfall data across Nepal were obtained from the Department of Hydrology and Meteorology, Kathmandu, Nepal (https://dhm.gov.np/).

Maxwell conjectured that the electric field generated by n point charges in generic position has at most (n-1)^2 isolated zeroes. The first (nonoptimal) upper bound was only obtained in 2007 by Gabrielov, Novikov, and Shapiro, who also posed two additional interesting conjectures. In this article, we give the best upper bound known to date on the number of zeroes of the electric field, and construct a counterexample to Conjecture 1.8 by Gabrielov, Novikov, and Shapiro that the number of equilibria cannot exceed those of the distance function defined by the unit point charges. Finally, we note that it is quite possible that Maxwell's quadratic upper bound is not tight, so it is prudent to find lower bounds. Hence, we also explore examples and construct configurations of charges achieving the highest ratios of the number of electric field zeroes by point charges found to this day.","lang":"eng"}],"title":"Counting equilibria of the electrostatic potential","date_updated":"2026-07-22T06:33:54Z","status":"public","_id":"21931","type":"journal_article","doi":"10.1112/plms.70163","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Wiley","day":"01","date_published":"2026-05-01T00:00:00Z","language":[{"iso":"eng"}],"fulldoi":"https://doi.org/10.1112/plms.70163","external_id":{"arxiv":["2501.05315"]},"publication":"Proceedings of the London Mathematical Society","date_created":"2026-05-31T22:02:13Z","department":[{"_id":"HeEd"},{"_id":"TaHa"}],"scopus_import":"1","related_material":{"record":[{"status":"public","relation":"earlier_version","id":"21050"}]},"citation":{"ista":"Edelsbrunner H, Fillmore CD, Oliveira G. 2026.

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."}],"conference":{"name":"WWW: Web Conference","location":"Dubai","start_date":"2026-06-29","end_date":"2026-07-03"},"citation":{"ista":"Damie M, Cyffers EAL.
