In protein crystals and protein-protein complexes, intermolecular contacts alter this energy landscape, but the exact nature of this alteration is difficult to decipher. Understanding how the crystal lattice affects protein dynamics is crucial for crystallography-based studies of motion, yet its influence on collective motions remains unclear. Aromatic ring flips in the hydrophobic core represent sensitive probes of such dynamics. Here, we compare the kinetics of aromatic ring flips in the protein GB1 in crystals, in complex with its binding partner IgG, and in solution, combining advanced isotope labeling with quantitative NMR methods. We show that rings in the core flip nearly a thousand times less frequently in crystals than in solution. Enhanced-sampling molecular dynamics simulations, based on a new crystal structure, reproduce these elevated barriers and reveal how the crystal restrains motions.

The laser phase plate (LPP) has recently demonstrated that an amplified, focused laser standing wave reliably phase shifts the electron beam, achieving phase-contrast TEM. Building on the single-beam LPP, here we introduce the crossed laser phase plate (XLPP): two laser standing waves which intersect in the diffraction plane. We present a theoretical model for the XLPP inside the microscope and show that, relative to the original LPP, it increases information transfer at low spatial frequencies while suppressing ghost images formed by Kapitza-Dirac diffraction. We also present a simple acquisition scheme, enabled by the XLPP, which further suppresses ghosts. Finally, we discuss practical considerations of XLPP design and show experimental results from a prototype.

However, previous designs have been unstable and compromised the high-resolution signal and have thus been unable to surpass results achieved by standard cryo-EM. Here, we show that the laser phase plate (LPP), installed in a modern, custom Titan Krios microscope, enhances the resolution in single-particle reconstruction of small proteins by improving specimen-motion correction and recovery of information from the early frames, as well as particle visualization, three-dimensional classification, and alignment. These advances use standard defocus ranges and reconstruction procedures but open the door to LPP-tailored protocols, offering further improvements by leveraging the LPP demonstrated here.","lang":"eng"}],"year":"2026","citation":{"chicago":"Petrov, Petar N, Jessie T.

However, most existing FEWS remain prediction‐centric, treating decision‐making as a downstream consumer of hazard forecasts while offering limited support for uncertainty interpretation, risk communication, and real‐world response. This Perspective presents a vision and blueprint for a novel inland FEWS‐decision‐making (FEWS‐DM) framework that repositions decision‐making as an equal partner in the forecasting process—not a passive recipient of its outputs. The framework is built on three tightly coupled, co‐evolving thrusts: Physical Science (T1), which advances flood prediction with quantified uncertainty informed by decision relevance; Human Science (T2), which incorporates psychology, behavior, and cultural and institutional context; and Decision Science (T3), which unifies physical predictions and human factors through principled, utility‐based decision support with end‐to‐end uncertainty management. Rather than treating T1 as a solved problem, FEWS‐DM recognizes that forecast development itself must be shaped by decision needs through continuous bidirectional feedback. We identify key scientific, behavioral, and operational challenges limiting such integration and discuss the enabling role of AI, while emphasizing human‐centered design and community feedback as essential for building trust and improving flood risk management.</jats:p>","lang":"eng"}],"doi":"10.1029/2026ef008857","oa":1,"language":[{"iso":"eng"}],"DOAJ_listed":"1","date_updated":"2026-08-06T09:02:33Z","author":[{"last_name":"Tran","first_name":"Vinh Ngoc","full_name":"Tran, Vinh Ngoc"},{"last_name":"Huan","first_name":"Xun","full_name":"Huan, Xun"},{"last_name":"Antar","first_name":"Anindya Das","full_name":"Antar, Anindya Das"},{"full_name":"Banovic, Nikola","first_name":"Nikola","last_name":"Banovic"},{"full_name":"Bednar, Jeff H.","last_name":"Bednar","first_name":"Jeff H."},{"last_name":"Bergt","first_name":"Shannon Marie","full_name":"Bergt, Shannon Marie"},{"first_name":"Chen","last_name":"Cheng","full_name":"Cheng, Chen"},{"full_name":"Dominguez, Francina","first_name":"Francina","last_name":"Dominguez"},{"full_name":"Fatichi, Simone","id":"cf8e546b-a9b0-11f0-a43b-aa89ed1b56d6","last_name":"Fatichi","first_name":"Simone"},{"first_name":"Richard","last_name":"Gonzalez","full_name":"Gonzalez, Richard"},{"last_name":"Gray","first_name":"Kevin","full_name":"Gray, Kevin"},{"first_name":"Brian","last_name":"Jewett","full_name":"Jewett, Brian"},{"first_name":"Jongho","last_name":"Kim","full_name":"Kim, Jongho"},{"first_name":"Phong V.V.","last_name":"Le","full_name":"Le, Phong V.V."},{"last_name":"Lu","first_name":"Dan","full_name":"Lu, Dan"},{"full_name":"Prabhudesai, Snehal","first_name":"Snehal","last_name":"Prabhudesai"},{"first_name":"Deffi","last_name":"Putri","full_name":"Putri, Deffi"},{"full_name":"Rath, Sudhansu","last_name":"Rath","first_name":"Sudhansu"},{"full_name":"Sargsyan, Khachik","first_name":"Khachik","last_name":"Sargsyan"},{"first_name":"Sarah H.","last_name":"Whitaker","full_name":"Whitaker, Sarah H."},{"first_name":"Daniel B.","last_name":"Wright","full_name":"Wright, Daniel B."},{"full_name":"Xu, Donghui","last_name":"Xu","first_name":"Donghui"},{"last_name":"Ziker","first_name":"John P.","full_name":"Ziker, John P."},{"full_name":"Ivanov, Valeriy Y.","last_name":"Ivanov","first_name":"Valeriy Y."}],"oa_version":"Published Version","fulldoi":"https://doi.org/10.1029/2026ef008857","article_number":"e2026EF008857","publication_identifier":{"eissn":["2328-4277"]}},{"department":[{"_id":"BiCh"}],"article_type":"original","volume":164,"article_processing_charge":"No","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2512.18029"}],"issue":"6","citation":{"mla":"Kim, Dongjin, and Bingqing Cheng. “Long-Range Electrostatics for Machine Learning Interatomic Potentials Is Easier than We Thought.” <i>The Journal of Chemical Physics</i>, vol. 164, no. 6, 060901, AIP Publishing, 2026, doi:<a href=\"https://doi.org/10.1063/5.0316886\">10.1063/5.0316886</a>.","short":"D.

In this Perspective, we distill two design principles behind the Latent Ewald Summation framework, which can capture long-range interactions, charges, and electrical response just by learning from standard energy and force training data: (i) use a Coulomb functional form with environment-dependent charges to capture electrostatic interactions, and (ii) avoid explicit training on ambiguous density functional theory partial charges. When both principles are satisfied, substantial flexibility remains: essentially any short-range MLIP can be augmented; charge equilibration schemes can be added when desired; dipoles and Born effective charges can be inferred or fine-tuned; and charge/spin-state embeddings or tensorial targets can be further incorporated. We also discuss current limitations and open challenges. Together, these minimal, physics-guided design rules suggest that incorporating long-range electrostatics into MLIPs is simpler and perhaps more broadly applicable than is commonly assumed."}],"acknowledgement":"B.C. thanks Christoph Dellago for his mentorship and influence.

However, the role of warming in regulating SOC storage remains debated. Here, we leverage literature data of warming experiments and a mechanistic model to explore SOC responses to warming by partitioning the effects of air and soil warming. Both the literature data and numerical model show that air and soil warming play distinct roles in regulating SOC storage, with insignificant SOC responses under air warming and negative responses to soil warming. Soil warming decreases SOC storage because of temperature-driven increases in decomposition rate. Air warming effects on SOC are more complex. In some cases, air warming can lead to a lower NPP and higher decomposition rate. In others, air warming can stimulate NPP and enhance soil moisture depletion that inhibits SOC decomposition. Once the latter mechanisms dominate, SOC storage increases with air warming."}],"citation":{"mla":"Luo, Zhaoyang, et al. “Air and Soil Warming Have Different Effects on Soil Organic Carbon Storage.” <i>Communications Earth &#38; Environment</i>, vol. 7, 394, Springer Nature, 2026, doi:<a href=\"https://doi.org/10.1038/s43247-026-03367-5\">10.1038/s43247-026-03367-5</a>.","short":"Z.

Vegetation responses to environmental stress manifest first as plant physiological changes, and at later stages through changes in canopy structure. Here we leverage CO2 and water flux data from 103 eddy covariance towers and satellite thermal images to assess whether current satellite reconstructions of solar-induced chlorophyll fluorescence capture these plant mechanisms. After removing seasonality using standardized anomalies (z-scores), we found that the relationship between tower-observed gross primary productivity and fluorescence reconstructions considerably weakened across a wide range of biomes. This loss of correlation results from a decoupling between stomatal responses and the physiological emission yield (ΦF) of fluorescence reconstructions during soil and atmospheric dry periods. The consequence is that productivity derived from fluorescence reconstructions will be progressively overestimated as dry conditions persist."}],"year":"2026","doi":"10.1038/s43247-025-03035-0","tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"intvolume":"         7","month":"01","quality_controlled":"1","title":"Limited capability of current satellite solar-induced chlorophyll fluorescence reconstructions to capture stomatal responses to environmental stresses","type":"journal_article","das_tickbox":"1","status":"public","publication_status":"published","publisher":"Springer Nature","OA_type":"gold","date_created":"2026-07-27T12:30:24Z","date_published":"2026-01-05T00:00:00Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","OA_place":"publisher","publication":"Communications Earth & Environment","_id":"22528","day":"05"},{"language":[{"iso":"eng"}],"DOAJ_listed":"1","date_updated":"2026-08-11T05:49:20Z","author":[{"first_name":"Lukas","last_name":"Einramhof","id":"f1497a1a-72ef-11ef-b75a-fd877bbf6e8c","full_name":"Einramhof, Lukas"},{"full_name":"Bugnet, Lisa Annabelle","orcid":"0000-0003-0142-4000","first_name":"Lisa Annabelle","last_name":"Bugnet","id":"d9edb345-f866-11ec-9b37-d119b5234501"},{"last_name":"Calcaferro","first_name":"L.

In addition, strong magnetic fields have recently been measured through asteroseismology in the radiative interiors of red giant stars, the progenitors of white dwarfs. To investigate the potential connection between these observations, we revisited the fossil field framework using asteroseismic detections to constrain the strength of such magnetic fields as red giants evolve into the white dwarf stage. We assumed that the magnetic field was either created during the core convection on the main sequence or that it fills the radiative interior as the star evolves on the red giant branch. From these initial conditions, we evolved the magnetic flux, allowing for magnetic diffusion along the evolution of a modeled 1.5 M⊙ star. We find that measured field strengths in red giants attributed to the hydrogen-burning shell are compatible with the field amplitudes and emergence timescales of magnetized white dwarfs. On the contrary, magnetic fields generated solely from a convective-core dynamo on the main sequence and detectable on the red giant branch would be buried too deep in the star and would not match the breakout timescales or the field strengths of magnetic white dwarfs. Therefore, for us to connect magnetic fields observed along the late evolution of stars via a fossil field we would need to find a broadly magnetized internal radiative zone on the red giant branch."}],"ddc":["520"],"doi":"10.1051/0004-6361/202659069","dataavailabilitystatement":"We used MESA version 24.08.1.

In this work, we study combinatorial bifurcations within the framework of combinatorial dynamical systems—a young but already well-established theory. We introduce the Conley–Morse persistence barcode, a compact algebraic descriptor of combinatorial bifurcations. This barcode captures structural changes in a dynamical system at the level of Morse decompositions and provides a characterization of the nature of observed transitions in terms of the Conley index. The construction of the Conley–Morse persistence barcode builds upon ideas from topological persistence. Specifically, we consider a persistence module obtained from the Conley index of invariant sets indexed over a poset. Using gentle algebras, we prove that this module decomposes into simple intervals (bars) and compute them by adapting the zigzag persistence algorithm to our purpose.","lang":"eng"}],"department":[{"_id":"HeEd"}],"project":[{"_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413","name":"IST-BRIDGE: International postdoctoral program","call_identifier":"H2020"}],"article_type":"original","article_processing_charge":"Yes (via OA deal)","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s10208-026-09766-6"}],"researchdata_availability":"no","fulldoi":"https://doi.org/10.1007/s10208-026-09766-6","oa_version":"Published Version","corr_author":"1","publication_identifier":{"eissn":["1615-3383"],"issn":["1615-3375"]},"ec_funded":1,"PlanS_conform":"1","oa":1,"date_updated":"2026-08-11T06:13:33Z","author":[{"last_name":"Dey","first_name":"Tamal K.","full_name":"Dey, Tamal K."},{"orcid":"0000-0001-9789-9750","full_name":"Lipiński, Michał","first_name":"Michał","id":"dfffb474-4317-11ee-8f5c-fe3fc95a425e","last_name":"Lipiński"},{"id":"15ebd7cf-15bf-11ee-aebd-bb4bb5121ea8","last_name":"Soriano Trigueros","first_name":"Manuel","full_name":"Soriano Trigueros, Manuel","orcid":"0000-0003-2449-1433"}],"supplementarymaterial":"yes","language":[{"iso":"eng"}],"publication":"Foundations of Computational Mathematics","_id":"22648","OA_place":"publisher","day":"04","keyword":["Multivector field","Conley index","Morse decomposition","Bifurcation","Continuation","Zigzag persistence","Persistence barcode","Gentle algebra"],"publication_status":"epub_ahead","publisher":"Springer","date_created":"2026-08-05T06:11:30Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2026-08-04T00:00:00Z","OA_type":"hybrid","quality_controlled":"1","month":"08","status":"public","title":"Conley-Morse persistence barcode: A homological signature of combinatorial bifurcations","das_tickbox":"0","type":"journal_article","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"external_id":{"arxiv":["2504.17105"]},"has_accepted_license":"1"},{"fulldoi":"https://doi.org/10.1016/j.ejrh.2026.103808","oa_version":"Published Version","researchdata_availability":"yes","publication_identifier":{"eissn":["2214-5818"]},"article_number":"103808","file":[{"success":1,"relation":"main_file","access_level":"open_access","date_created":"2026-08-11T06:45:46Z","checksum":"6a6545fc11b6c7948cdede877d19e3f3","date_updated":"2026-08-11T06:45:46Z","file_size":13155535,"creator":"dernst","file_id":"22680","file_name":"2026_JourHydrology_Castro.pdf","content_type":"application/pdf"}],"oa":1,"author":[{"first_name":"Joshua","last_name":"Castro","full_name":"Castro, Joshua"},{"first_name":"Catriona Louise","id":"001b0422-8d15-11ed-bc51-cab6c037a228","last_name":"Fyffe","full_name":"Fyffe, Catriona Louise"},{"id":"3caa3f91-1f03-11ee-96ce-e0e553054d6e","last_name":"Shaw","first_name":"Thomas","full_name":"Shaw, Thomas","orcid":"0000-0001-7640-6152"},{"last_name":"Miles","first_name":"Evan","full_name":"Miles, Evan"},{"full_name":"Potter, Emily","first_name":"Emily","last_name":"Potter"},{"last_name":"Hoelzle","first_name":"Martin","full_name":"Hoelzle, Martin"},{"last_name":"Varghese","first_name":"Vinisha","full_name":"Varghese, Vinisha"},{"id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","last_name":"Pellicciotti","first_name":"Francesca","full_name":"Pellicciotti, Francesca","orcid":"0000-0002-5554-8087"}],"date_updated":"2026-08-11T06:48:28Z","supplementarymaterial":"yes","language":[{"iso":"eng"}],"DOAJ_listed":"1","citation":{"short":"J.

We characterise wetland distribution, seasonality and persistence and evaluate their spatial association with glaciers and seasonal snow. Using Landsat 7 and 8 imagery, we build three-month seasonal land cover maps from 2013 to 2022 using a Random Forest classification and an Albedo Retrieval approach.\r\nNew hydrological insights for the region: Wetland area decreases by 38% from the end of the wet season (October to December) to the end of the dry season (July to September). Pixel transitions indicate that wetlands primarily transform to and from agricultural and pasture lands. Highly persistent wetlands are located above 4600 m a.s.l. and closer to glaciers than less persistent wetlands. We identified three wetland seasonal drying patterns. Basins with delayed and slow dry-out wetlands were more common at higher elevations but were not always in glacierised catchments, suggesting meltwater may maintain wetlands in the early dry season. We provide the first large-scale picture of wetland seasonality, and the basis for modelling the processes that sustain wetlands in tropical high mountains.","lang":"eng"}],"acknowledgement":"Joshua Castro acknowledges the support and funding of the Swiss Government Excellence Scholarships (ESKAS-Nr: 2022.0416) and the Doc.

However, it is expected that some TDEs will occur outside the galaxy nucleus, arising from wandering black holes (BHs) originating in galaxy mergers. Here, we present observations of TDE 2025abcr, the first optical TDE discovered in the outskirts of a host galaxy. The TDE was identified by a custom “off-nuclear” implementation of the machine learning classifier tdescore, which classifies new ZTF transients based on their lightcurves. Follow-up observations confirm that TDE 2025abcr is a TDE-H+He, occurring 9\r\n5 (9.3 kpc projected distance) from the nucleus of a massive galaxy (M⋆ = 1011.18±0.03M⊙) with a central BH mass of 108.82±0.65M⊙. TDE 2025abcr itself was likely disrupted by a much lighter BH (106.09±0.53M⊙, as estimated with peak luminosity scaling relations). The BH was either dynamically ejected from the nucleus or lies at the center of a very faint tidally stripped dwarf galaxy undergoing a minor merger. Late-time observations of TDE 2025abcr could confirm the origin of this apparent “wandering” BH. The rate of highly offset (≳3 kpc) TDEs can be constrained to <10% of the nuclear TDE rate, but our discovery implies that many dozens of similar sources will be detected by the Vera C. Rubin Observatory each year with resolvable offsets.","lang":"eng"}],"arxiv":1,"scopus_import":"1","ddc":["520"],"doi":"10.3847/2041-8213/ae77f3","article_type":"original","volume":1006,"department":[{"_id":"IlCa"}],"issue":"2","article_processing_charge":"Yes","quality_controlled":"1","month":"07","type":"journal_article","file_date_updated":"2026-08-11T07:45:16Z","das_tickbox":"0","title":"TDE 2025abcr: A tidal disruption event in the outskirts of a massive galaxy","status":"public","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"intvolume":"      1006","external_id":{"arxiv":["2602.10180"]},"has_accepted_license":"1","OA_place":"publisher","_id":"22675","publication":"The Astrophysical Journal Letters","day":"27","publisher":"IOP Publishing","publication_status":"published","OA_type":"gold","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_published":"2026-07-27T00:00:00Z","date_created":"2026-08-11T06:19:19Z"},{"researchdata_availability":"yes","fulldoi":"https://doi.org/10.1371/journal.pgen.1012173","corr_author":"1","oa_version":"Published Version","file":[{"access_level":"open_access","date_created":"2026-08-11T07:53:14Z","date_updated":"2026-08-11T07:53:14Z","checksum":"3e2d3acc179f4672c49217ae4a6e237c","file_size":2462781,"creator":"dernst","content_type":"application/pdf","file_id":"22683","file_name":"2026_PloSGenetics_Field.pdf","success":1,"relation":"main_file"}],"publication_identifier":{"eissn":["1553-7404"]},"article_number":"e1012173","pmid":1,"PlanS_conform":"1","oa":1,"language":[{"iso":"eng"}],"DOAJ_listed":"1","author":[{"full_name":"Field, David","orcid":"0000-0002-4014-8478","first_name":"David","id":"419049E2-F248-11E8-B48F-1D18A9856A87","last_name":"Field"},{"full_name":"Stankowski, Sean","id":"43161670-5719-11EA-8025-FABC3DDC885E","last_name":"Stankowski","first_name":"Sean"},{"last_name":"Reiter","first_name":"Taylor","full_name":"Reiter, Taylor"},{"first_name":"Jitka","last_name":"Polechova","full_name":"Polechova, Jitka"},{"full_name":"Bradley, Desmond","last_name":"Bradley","first_name":"Desmond"},{"full_name":"Richardson, Daniel M.","first_name":"Daniel M.","last_name":"Richardson"},{"full_name":"Whibley, Annabel","first_name":"Annabel","last_name":"Whibley"},{"last_name":"Pal","id":"6AAB2240-CA9A-11E9-9C1A-D9D1E5697425","first_name":"Arka","orcid":"0000-0002-4530-8469","full_name":"Pal, Arka"},{"full_name":"Shipilina, Daria","orcid":"0000-0002-1145-9226","last_name":"Shipilina","id":"428A94B0-F248-11E8-B48F-1D18A9856A87","first_name":"Daria"},{"full_name":"Boell, Louis","first_name":"Louis","last_name":"Boell"},{"orcid":"0000-0001-6118-0541","full_name":"Pickup, Melinda","first_name":"Melinda","id":"2C78037E-F248-11E8-B48F-1D18A9856A87","last_name":"Pickup"},{"last_name":"Xue","first_name":"Yongbiao","full_name":"Xue, Yongbiao"},{"last_name":"Coen","first_name":"Enrico","full_name":"Coen, Enrico"},{"first_name":"Nicholas H","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","last_name":"Barton","orcid":"0000-0002-8548-5240","full_name":"Barton, Nicholas H"}],"date_updated":"2026-08-11T07:55:22Z","supplementarymaterial":"yes","citation":{"ieee":"D.

Much effort has focused on\r\nlocating candidate genes and potential barrier loci by scanning genomes for regions\r\nof excess differentiation (FST). An alternative, and perhaps more robust approach, is\r\nto scan for genomic regions exhibiting steep clines in allele frequency across a hybrid\r\nzone. We develop a computationally efficient method for approximating cline parameters\r\nfor large number of loci, and apply it to genomic data from across a hybrid zone\r\nbetween flower colour varieties of Antirrhinum majus (A. m. m var. pseudomajus and\r\nA. m. m var. striatum). Most steep clines are clustered in seven genomic regions,\r\nonly four of which were present from FST scans between all pair-wise comparisons.\r\nSix of these regions carry previously identified loci that influence flower colour in the\r\nhybrid zone. The seventh region harbours a novel locus, RUBIA, modifying magenta\r\nintensity. Clines at RUBIA approached fixation on the magenta side of the hybrid\r\nzone, whilst remaining polymorphic on the yellow side. This polymorphism on the\r\nyellow side may reflect a smaller phenotypic effect of RUBIA in yellow compared\r\nto magenta genetic backgrounds. Our findings illustrate how whole-genome cline\r\nscans in hybrid zones can robustly detect genomic regions contributing to phenotypic\r\ndifferences and highlight how different reproductive barrier loci interact across the\r\ngenome.","lang":"eng"}],"year":"2026","dataavailabilitystatement":"The raw DNA poolSeq data and RNA data have been uploaded to SRA under accession number PRJNA1232105.

Using the SDSS DR16 quasar catalogue, we estimate the velocity offset, $\\Delta v$, as the difference between the broad H$\\beta$ redshift and a noise-weighted redshift from narrow lines ([O iii] 5007, [O ii] 3728, and Ca ii 3934). We adopt the redshift-relative colour excess $\\Delta (g-i)$ as a proxy for dust column density. Analysing $\\sim 10^{5}$ quasars that meet basic spectral quality requirements, we find a modest but highly significant positive correlation between $|\\Delta v|$ and $\\Delta (g-i)$ (Spearman $r\\simeq 0.12$ and Pearson $r\\simeq 0.13$, with $p\\ll 10^{-10}$ in both cases). The fraction of highly obscured quasars increases with $|\\Delta v|$, indicating that the correlation is driven by a dust-reddened subpopulation. The result is robust to the choice of minimum $|\\Delta v|$ threshold and to the line redshift estimator (peak vs. centroid). As expected, the correlation is largely absent when velocity offsets are computed between narrow emission lines. We find systematic differences between redshifted and blueshifted subsamples, which may point to residual velocity biases or additional physical effects (e.g. winds, inflows, orientation-dependent obscuration, or asymmetric broad-line regions). Recoiling massive black holes provide a natural explanation for the observed correlation, but alternative scenarios should be explored. If confirmed, this would enable population-level constraints on massive black hole merger rates, recoil dynamics, and active galactic nuclei disc properties."}],"year":"2026","acknowledgement":"We thank Paul Hewett for useful discussions, and Qiaoya Wu for guidance on the data presented in Q.

We consider the prototypical problem of estimating two statistically independent signals in a mixed generalized linear model with Gaussian covariates. Spectral methods are a popular class of estimators which output the top two eigenvectors of a suitable data-dependent matrix. However, despite the wide applicability, their design is still obtained via heuristic considerations, and the number of samples 𝑛 needed to guarantee recovery is superlinear in the signal dimension 𝑑. In this paper, we develop exact asymptotics on spectral methods in the challenging proportional regime in which 𝑛,𝑑 grow large and their ratio converges to a finite constant. This allows us optimize the design of the spectral method, and combine it with a simple linear estimator, to minimize the estimation error. Our characterization exploits a mix of tools from random matrices, free probability, and the theory of approximate message passing algorithms. Numerical simulations for mixed linear regression and phase retrieval demonstrate the advantage enabled by our analysis over existing designs of spectral methods."}],"year":"2026","acknowledgement":"The first and second authors were partially supported by the 2019 Lopez-Loreta prize.","arxiv":1,"scopus_import":"1","doi":"10.1137/24m1702854","ddc":["000"],"article_type":"original","project":[{"name":"Prix Lopez-Loretta 2019 - Marco Mondelli","_id":"059876FA-7A3F-11EA-A408-12923DDC885E"}],"volume":8,"department":[{"_id":"MaMo"}],"issue":"2","article_processing_charge":"Yes (in subscription journal)","fulldoi":"https://doi.org/10.1137/24m1702854","corr_author":"1","oa_version":"Published Version","researchdata_availability":"no","file":[{"success":1,"relation":"main_file","access_level":"open_access","date_updated":"2026-07-01T06:22:15Z","creator":"dernst","file_size":1210346,"checksum":"5cfd350dc64d1476063e959316dbff65","date_created":"2026-07-01T06:22:15Z","file_id":"22230","file_name":"2026_SIAMJourmathDataScience_Zhang.pdf","content_type":"application/pdf"}],"publication_identifier":{"eissn":["2577-0187"]},"PlanS_conform":"1","oa":1,"language":[{"iso":"eng"}],"supplementarymaterial":"no","author":[{"full_name":"Zhang, Yihan","first_name":"Yihan","last_name":"Zhang"},{"full_name":"Mondelli, Marco","orcid":"0000-0002-3242-7020","first_name":"Marco","id":"27EB676C-8706-11E9-9510-7717E6697425","last_name":"Mondelli"},{"full_name":"Venkataramanan, Ramji","first_name":"Ramji","last_name":"Venkataramanan"}],"date_updated":"2026-08-12T06:23:07Z"},{"external_id":{"arxiv":["2212.03128"]},"has_accepted_license":"1","intvolume":"         8","status":"public","title":"Chromatic alpha complexes","type":"journal_article","quality_controlled":"1","month":"03","date_created":"2025-11-02T23:01:33Z","date_published":"2026-03-01T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","OA_type":"green","publication_status":"published","mathsc":["62R40","55N31","68T09","57Q70"],"publisher":"AIMS","page":"30-62","day":"01","related_material":{"record":[{"relation":"earlier_version","id":"15091","status":"public"}]},"keyword":["Topological data analysis","Delaunay mosaic","alpha complex","chromatic sets","persistent homology","kernel/image/cokernel persistent homology","radius function","discrete Morse theory","exact sequences"],"publication":"Foundations of Data Science","_id":"20585","OA_place":"repository","author":[{"full_name":"Cultrera di Montesano, Sebastiano","orcid":"0000-0001-6249-0832","first_name":"Sebastiano","id":"34D2A09C-F248-11E8-B48F-1D18A9856A87","last_name":"Cultrera di Montesano"},{"full_name":"Draganov, Ondrej","orcid":"0000-0003-0464-3823","last_name":"Draganov","id":"2B23F01E-F248-11E8-B48F-1D18A9856A87","first_name":"Ondrej"},{"first_name":"Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","last_name":"Edelsbrunner","full_name":"Edelsbrunner, Herbert","orcid":"0000-0002-9823-6833"},{"full_name":"Saghafian, Morteza","first_name":"Morteza","id":"f86f7148-b140-11ec-9577-95435b8df824","last_name":"Saghafian"}],"date_updated":"2026-08-12T06:19:48Z","language":[{"iso":"eng"}],"oa":1,"publication_identifier":{"eissn":["2639-8001"]},"ec_funded":1,"oa_version":"Preprint","fulldoi":"https://doi.org/10.3934/fods.2025003","corr_author":"1","article_processing_charge":"No","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2212.03128","open_access":"1"}],"department":[{"_id":"HeEd"}],"article_type":"original","project":[{"name":"Alpha Shape Theory Extended","call_identifier":"H2020","_id":"266A2E9E-B435-11E9-9278-68D0E5697425","grant_number":"788183"},{"_id":"268116B8-B435-11E9-9278-68D0E5697425","grant_number":"Z00342","name":"Mathematics, Computer Science","call_identifier":"FWF"},{"grant_number":"I02979-N35","_id":"2561EBF4-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","name":"Persistence and stability of geometric complexes"}],"volume":8,"ddc":["510"],"doi":"10.3934/fods.2025003","arxiv":1,"scopus_import":"1","acknowledgement":"This project has received funding from the European Research\r\nCouncil (ERC) under the European Union’s Horizon 2020 research and innovation\r\nprogramme, grant no. 788183, from the Wittgenstein Prize, Austrian Science Fund\r\n(FWF), grant no.

Armstrong, J.-C. Mourrat, and M. Novack [2], with the notion of second-order lifts of reversible diffusion processes, recently introduced by A. Eberle and the second author [30]. We give an abstract, yet fully constructive, presentation of the theory, so that it can be applied to a large class of linear kinetic equations. As this hypocoercivity technique does not twist the reference norm, we can recover accurate and sharp convergence rates in various models. Among those, adaptive Langevin dynamics (ALD) is discussed in full detail and we show that for near-quadratic potentials, with suitable choices of parameters, it is a near-optimal second-order lift of the overdamped Langevin dynamics. As a further consequence, we observe that the Generalised Langevin Equation (GLE) is also a second-order lift, as the standard (kinetic) Langevin dynamics are, of the overdamped Langevin dynamics. Then, convergence of (GLE) cannot exceed ballistic speed, i.e. the square root of the rate of the overdamped regime. We illustrate this phenomenon with explicit computations in a benchmark Gaussian case."}],"year":"2026","acknowledgement":"We would like to thank Andreas Eberle and Gabriel Stoltz for many helpful discussions.

Given such a decomposition, one can define a further summary of its flow structure by what is called a connection matrix. These matrices, a generalization of Morse boundary operators from classical Morse theory, capture the connections made by the flows among the critical structures—such as attractors, repellers, and orbits—in a vector field. Recently, in the context of combinatorial dynamics, an efficient persistence-like algorithm to compute connection matrices has been proposed in Dey, Lipiński, Mrozek, and Slechta [SIAM J. Appl. Dyn. Syst., 23 (2024), pp. 81–97]. We show that, actually, the classical persistence algorithm with exhaustive reduction retrieves connection matrices, both simplifying the algorithm of Dey et al. and bringing the theory of persistence closer to combinatorial dynamical systems. We supplement this main result with an observation: the concept of persistence as defined for scalar fields naturally adapts to Morse decompositions whose Morse sets are filtered with a Lyapunov function. We conclude by presenting preliminary experimental results."}],"year":"2026","acknowledgement":"This research was supported by NSF grants DMS-2301360 and CCF-2437030 as well as from the European Union's Horizon 2020 research and innovation programme under Marie Sk\\lodowska-Curie grant 101034413.\r\n","ddc":["510"],"doi":"10.1137/25m1739406","citation":{"mla":"Dey, Tamal K., et al. “Computing a Connection Matrix and Persistence Efficiently from a Morse Decomposition.” <i>SIAM Journal on Applied Dynamical Systems</i>, vol. 25, no. 1, SIAM, 2026, pp. 108–30, doi:<a href=\"https://doi.org/10.1137/25m1739406\">10.1137/25m1739406</a>.","short":"T.K.

Previous works showed that the complexity of computing the diameter mainly depends on the object types: for unit disks and squares in 2D, the problem is solvable in truly subquadratic time [Chan et al., 2025], while for other objects, including unit segments and equilateral triangles in 2D or unit balls and axis-parallel unit cubes in 3D, there is no truly subquadratic time algorithm under the Orthogonal Vector (OV) hypothesis [Bringmann et al., 2022]. \r\nWe undertake a comprehensive study of computing the diameter of geometric intersection graphs for various types of objects. We discover many new irregularities, showing that the landscape is extremely nuanced: the source of hardness is a combination of the object type, the true diameter value, and how the objects intersect with each other. Our highlighted results for the 2D case include:  \r\n1) The diameter of non-degenerate, axis-aligned line segments can be computed in truly subquadratic time. Previous hardness result [Bringmann et al., 2022] for line segments applies only to degenerate instances. On the other hand, for the degenerate case, we show that a truly subquadratic time algorithm exists when the true diameter is constant. \r\n2) An almost-linear-time algorithm for unit-square graphs of constant diameter. Previous algorithms [Duraj et al., 2024; Chan et al., 2025] rely on succinct representation assuming bounded VC-dimension; for such a strategy Ω(n^{7/4}) time is an inherent barrier. \r\n3) An Õ(n^{4/3})-time algorithm to decide if the diameter of a unit-disk graph is at most 2. This improves upon the recent algorithm with running time Õ(n^{2-1/9}) [Chan et al., 2025]. \r\n4) Deciding if the diameter of intersection graphs of fat triangles or line segments is at most 2 is truly subquadratic-hard under fine-grained complexity assumptions. Previous lower bounds [Bringmann et al., 2022] only hold when deciding if diameter is at most 3.  Our findings are presented in a pair of papers. This paper focuses solely on the 2D case, while the companion paper is devoted to higher-dimensional cases.","lang":"eng"}],"arxiv":1,"scopus_import":"1","ddc":["000"],"doi":"10.4230/LIPICS.ICALP.2026.54","citation":{"ieee":"T.
