In this study, we aim to constrain the massive binary CE phase by systematically reconstructing three observed BH X-ray binaries (BHXBs): GRO J1655-40, SAX J1819.3-2525, and 4U 1543-47. Through comprehensive binary evolution simulations and parametric supernova modeling, we establish lower limits for the CE efficiency parameters under different energy considerations within the standard energy formalism. Specifically, we derive minimum values for three cases: α0.5U and αU, representing CE efficiencies with half and all of the internal energy contributing to the envelope ejection, respectively, and αH, accounting for the envelope’s enthalpy. Our analysis reveals that the self-consistent formation of these three BHXBs requires CE efficiency parameters satisfying α0.5U ≳ 6.7, αU ≳ 4.2, and αH ≳ 1.7. Notably, we find no viable solutions with CE efficiency values below unity, even when considering the most extreme scenarios, in which the envelope binding energy is significantly reduced through enthalpy inclusion. Our results strongly imply that either additional energy sources are required or the formalism itself must be revised. Furthermore, we quantitatively assess the impact of BH natal kicks on our results. A key finding is that 4U 1543-47’s formation requires substantial natal kicks (≳50 km s−1), as lower kick velocities are incompatible with isolated binary evolution.","lang":"eng"}],"department":[{"_id":"YlGo"}],"publisher":"IOP Publishing","author":[{"full_name":"Li, Zhenwei","first_name":"Zhenwei","last_name":"Li"},{"full_name":"Wei, Dandan","last_name":"Wei","first_name":"Dandan","id":"5dd129bd-0601-11ef-b325-833284687b76"},{"full_name":"Jia, Shi","first_name":"Shi","last_name":"Jia"},{"full_name":"Chen, Hailiang","first_name":"Hailiang","last_name":"Chen"},{"first_name":"Hongwei","last_name":"Ge","full_name":"Ge, Hongwei"},{"full_name":"Chen, Zhuo","first_name":"Zhuo","last_name":"Chen"},{"first_name":"Yangyang","last_name":"Zhang","full_name":"Zhang, Yangyang"},{"full_name":"Chen, Xuefei","first_name":"Xuefei","last_name":"Chen"},{"first_name":"Zhanwen","last_name":"Han","full_name":"Han, Zhanwen"}],"oa":1,"scopus_import":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","has_accepted_license":"1","date_published":"2026-06-10T00:00:00Z","article_number":"31","day":"10","doi":"10.3847/1538-4357/ae66fd","DOAJ_listed":"1","language":[{"iso":"eng"}],"quality_controlled":"1","intvolume":"      1004","acknowledgement":"We deeply thank the referee for a very careful reading and constructive comments that have led to the improvement of the manuscript.

Here, we explore the possibility that these sources are globular clusters in formation, with rest-frame UV arising from a very young stellar population and rest-frame optical from a short-lived supermassive (>104 M⊙) star. The spectral profiles of LRDs are broadly consistent with this scenario, though the observed temperatures and bolometric luminosities favor emission reprocessed by optically thick continuum-driven winds not fully captured by current models. The LRD z ∼ 5−7 UV luminosity function naturally evolves, under standard evolutionary and mass-loss prescriptions, into a present-day mass function with a turnover at log10(M*/M⊙) = 5.3 and an exponential cutoff at high masses, consistent with local globular cluster populations. We estimate the total present-day number density of LRDs formed across all redshifts to be ≈0.3 Mpc−3, similar within uncertainties to local globular clusters. The observed LRD redshift range matches the age distribution of metal-poor globular clusters, without current LRD counterparts to the metal-rich population. If LRDs are globular clusters in formation, we predict chemical abundance patterns characteristic of multiple stellar populations, including enhanced He and N, and potential Na–O and Al–Mg anticorrelations. These results offer a local perspective to explore this surprisingly abundant population of distant sources, and a potential new window into extreme stellar astrophysics in the early Universe."}],"file":[{"relation":"main_file","file_name":"2026_AstrophysicalJourLetters_Chisholm.pdf","content_type":"application/pdf","creator":"dernst","access_level":"open_access","success":1,"date_created":"2026-06-19T09:45:21Z","checksum":"66949af6e620c8ef37de42688829a3e3","date_updated":"2026-06-19T09:45:21Z","file_id":"22098","file_size":919919}],"file_date_updated":"2026-06-19T09:45:21Z","article_type":"original","author":[{"first_name":"John","last_name":"Chisholm","full_name":"Chisholm, John"},{"full_name":"Berg, Danielle A.","first_name":"Danielle A.","last_name":"Berg"},{"full_name":"Boylan-Kolchin, Michael","first_name":"Michael","last_name":"Boylan-Kolchin"},{"full_name":"De Graaff, Anna","last_name":"De Graaff","first_name":"Anna"},{"full_name":"Furtak, Lukas J.","last_name":"Furtak","first_name":"Lukas J."},{"full_name":"Kokorev, Vasily","last_name":"Kokorev","first_name":"Vasily"},{"last_name":"Matthee","first_name":"Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J"},{"full_name":"Muñoz, Julian B.","first_name":"Julian B.","last_name":"Muñoz"},{"full_name":"Naidu, Rohan P.","first_name":"Rohan P.","last_name":"Naidu"},{"full_name":"Sander, Andreas A.C.","first_name":"Andreas A.C.","last_name":"Sander"}],"publisher":"IOP Publishing","department":[{"_id":"JoMa"}],"has_accepted_license":"1","status":"public","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"scopus_import":"1","oa":1},{"supplementarymaterial":"yes","publisher":"IOP Publishing","department":[{"_id":"JoMa"}],"author":[{"last_name":"Fei","first_name":"Qinyue","full_name":"Fei, Qinyue"},{"last_name":"Fujimoto","first_name":"Seiji","full_name":"Fujimoto, Seiji"},{"full_name":"Naidu, Rohan P.","last_name":"Naidu","first_name":"Rohan P."},{"first_name":"John","last_name":"Chisholm","full_name":"Chisholm, John"},{"first_name":"Hakim","last_name":"Atek","full_name":"Atek, Hakim"},{"first_name":"Gabriel","last_name":"Brammer","full_name":"Brammer, Gabriel"},{"full_name":"Asada, Yoshihisa","last_name":"Asada","first_name":"Yoshihisa"},{"full_name":"Berg, Danielle A.","first_name":"Danielle A.","last_name":"Berg"},{"full_name":"Bromm, Volker","first_name":"Volker","last_name":"Bromm"},{"first_name":"Lukas J.","last_name":"Furtak","full_name":"Furtak, Lukas J."},{"full_name":"Greene, Jenny E.","first_name":"Jenny E.","last_name":"Greene"},{"last_name":"Hsiao","first_name":"Tiger Yu Yang","full_name":"Hsiao, Tiger Yu Yang"},{"first_name":"Junehyoung","last_name":"Jeon","full_name":"Jeon, Junehyoung"},{"full_name":"Kokorev, Vasily","first_name":"Vasily","last_name":"Kokorev"},{"last_name":"Matthee","first_name":"Jorryt J","id":"7439a258-f3c0-11ec-9501-9df22fe06720","orcid":"0000-0003-2871-127X","full_name":"Matthee, Jorryt J"},{"last_name":"Natarajan","first_name":"Priyamvada","full_name":"Natarajan, Priyamvada"},{"first_name":"Richard","last_name":"Pan","full_name":"Pan, Richard"},{"last_name":"Richard","first_name":"Johan","full_name":"Richard, Johan"},{"last_name":"Saldana-Lopez","first_name":"Alberto","full_name":"Saldana-Lopez, Alberto"},{"full_name":"Schaerer, Daniel","last_name":"Schaerer","first_name":"Daniel"},{"first_name":"Marta","last_name":"Volonteri","full_name":"Volonteri, Marta"},{"full_name":"Zitrin, Adi","first_name":"Adi","last_name":"Zitrin"}],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"oa":1,"scopus_import":"1","has_accepted_license":"1","status":"public","article_processing_charge":"Yes","title":"A GLIMPSE of intermediate mass Black Holes in the epoch of reionization: Witnessing the descendants of direct collapse?","arxiv":1,"oa_version":"Published Version","publication_status":"published","date_created":"2026-06-14T22:01:43Z","OA_type":"gold","issue":"2","article_type":"original","file_date_updated":"2026-06-22T08:03:55Z","dataavailabilitystatement":"10.17909/4byn-fe55 and 10.17909/v2y7-j922 used with Software: LMFIT (M.

Here, we present a systematic search for broad-line active galactic nuclei (AGNs) in some of the faintest high-z galaxies surveyed yet by combining ultra-deep JWST/NIRSpec G395M spectroscopy with the strong lensing aid in AS1063. By employing the profile of the [O iii]λ5007 emission lines as a template for narrow-line components and carefully cross-validating with mock observations, we identify a sample of 10 broad-line AGNs at 4.5 < z < 7.0 (eight secure, two tentative). The inferred BH masses from the broad Hα line explore the intermediate BH mass regime down to ∼105.5 M⊙. The stellar mass (M*) is estimated with a galaxy+AGN composite model, and we find the BH to stellar mass ratio spans down to MBH/M* ≲ 0.1%, unveiling populations on the empirical MBH–M* relation observed in the local Universe. We also derive the BH mass function and investigate its low-mass end at this epoch. While we confirm the agreement of our results with previous studies at MBH ≳ 106.5M⊙, we find the mass range of ∼105.5 M⊙ features an enhanced abundance with respect to the extrapolated best-fit Schechter function. Comparison with theoretical models suggests that a possible origin for this enhanced abundance is the direct-collapse BH formation, supporting the scenario that the direct collapse of massive gas clouds is a significant pathway for the earliest supermassive BHs.","lang":"eng"}],"file":[{"file_name":"2026_AstrophysicalJour_Fei.pdf","relation":"main_file","content_type":"application/pdf","creator":"dernst","checksum":"b04247996b8dcd0eb5387581706d1106","access_level":"open_access","success":1,"date_created":"2026-06-22T08:03:55Z","date_updated":"2026-06-22T08:03:55Z","file_size":19681834,"file_id":"22112"}],"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"month":"06","PlanS_conform":"1","OA_place":"publisher","year":"2026","date_updated":"2026-06-22T11:34:52Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","das_tickbox":"0","_id":"21999","day":"01","date_published":"2026-06-01T00:00:00Z","article_number":"244","DOAJ_listed":"1","doi":"10.3847/1538-4357/ae6248","researchdata_availability":"yes","intvolume":"      1003","acknowledgement":"We thank the anonymous referee for insightful comments, which significantly improved the manuscript.

However, its conventional implementation quickly becomes intractable on a computer: barycentric subdivision produces poorly shaped simplices, and the star condition introduces many vertices. To address these limitations, this article develops a subdivision scheme based on spherical Delaunay triangulations, which attains better refinement properties than barycentric subdivisions. Moreover, the star condition is reframed as two independent problems, one geometric and the other combinatorial, respectively tackled in the language of locally equiconnected spaces and the list homomorphism problem, allowing an exponential reduction in the number of vertices. Via a prototype implementation, we obtain simplicial complexes homotopy equivalent to Grassmannians and Stiefel manifolds up to dimension 5."}],"keyword":["Triangulation of manifolds","Simplicial approximation","CW complexes","Delaunay complexes","List homomorphism problem","Topological Data Analysis"],"file_date_updated":"2026-06-22T07:53:13Z","author":[{"id":"40ebcc9d-905f-11ef-bf0a-dc475da8a04e","first_name":"Raphaël","last_name":"Tinarrage","orcid":"0000-0002-1404-1095","full_name":"Tinarrage, Raphaël"}],"corr_author":"1","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","department":[{"_id":"UlWa"}],"supplementarymaterial":"yes","has_accepted_license":"1","status":"public","scopus_import":"1","conference":{"name":"SoCG: Symposium on Computational Geometry","end_date":"2026-06-05","start_date":"2026-06-02","location":"New Brunswick, NJ, United States"},"oa":1,"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"doi":"10.4230/LIPIcs.SoCG.2026.93","researchdata_availability":"no","date_published":"2026-05-27T00:00:00Z","article_number":"93:1-93:22","day":"27","volume":367,"ddc":["500"],"type":"conference","citation":{"apa":"Tinarrage, R.

However, in three or higher dimensions, there is no known truly subquadratic-time algorithm for any intersection graph of non-trivial objects, even basic ones such as unit balls or (axis-aligned) unit cubes. This was partially explained by the pioneering work of Bringmann et al. [Karl Bringmann et al., 2022] which gave several truly subquadratic lower bounds, notably for unit balls or unit cubes in 3D when the graph diameter Δ is at least Ω(log n), hinting at a pessimistic outlook for the complexity of the diameter problem in higher dimensions. In this paper, we substantially extend the landscape of diameter computation for objects in three and higher dimensions, giving a few positive results. Our highlighted findings include:  \r\n1) A truly subquadratic-time algorithm for deciding if the diameter of unit cubes in 3D is at most 3 (Diameter-3 hereafter), the first algorithm of its kind for objects in 3D or higher dimensions. Our algorithm is based on a novel connection to pseudolines, which is of independent interest. \r\n2) A truly subquadratic time lower bound for Diameter-3 of unit balls in 3D under the Orthogonal Vector (OV) hypothesis, giving the first separation between unit balls and unit cubes in the small diameter regime. Previously, computing the diameter for both objects was known to be quadratic hard when the diameter is Ω(log n) [Karl Bringmann et al., 2022]. \r\n3) A near-linear-time algorithm for Diameter-2 of unit cubes in 3D, generalizing the previous result for unit squares in 2D [Karl Bringmann et al., 2022]. \r\n4) A truly subquadratic-time algorithm and lower bound for Diameter-2 and Diameter-3 of rectangular boxes (of arbitrary dimension and sizes), respectively."}],"external_id":{"arxiv":["2603.21790"]},"department":[{"_id":"MoHe"}],"publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","project":[{"name":"Static and Dynamic Hierarchical Graph Decompositions","grant_number":"I05982","_id":"bda196b2-d553-11ed-ba76-8e8ee6c21103"}],"corr_author":"1","author":[{"last_name":"Chan","first_name":"Timothy M.","full_name":"Chan, Timothy M."},{"last_name":"Chang","first_name":"Hsien Chih","full_name":"Chang, Hsien Chih"},{"full_name":"Gao, Jie","last_name":"Gao","first_name":"Jie"},{"full_name":"Kisfaludi-Bak, Sándor","last_name":"Kisfaludi-Bak","first_name":"Sándor"},{"full_name":"Le, Hung","first_name":"Hung","last_name":"Le"},{"first_name":"Da Wei","id":"af77956b-e859-11ef-8dc9-d301b898e32f","last_name":"Zheng","full_name":"Zheng, Da Wei"}],"alternative_title":["LIPIcs"],"oa":1,"conference":{"location":"New Brunswick, NJ, United States","start_date":"2026-06-02","name":"SoCG: Symposium on Computational Geometry","end_date":"2026-06-05"},"scopus_import":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"status":"public","has_accepted_license":"1"},{"date_updated":"2026-06-22T08:21:09Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"22006","das_tickbox":"0","OA_place":"publisher","year":"2026","month":"05","publication_identifier":{"issn":["0302-9743"],"isbn":["9783032262196"],"eissn":["1611-3349"]},"ec_funded":1,"type":"conference","citation":{"apa":"Chalupa, M., Henzinger, T.

Signal First-Order Logic (SFO) offers expressive real-time specifications over such signals, but currently comes only with Boolean semantics and has no tool support. We provide the first robustness-based quantitative semantics for SFO, enabling the expression and evaluation of rich real-time properties beyond the scope of existing formalisms such as Signal Temporal Logic. To enable online monitoring, we identify a past-time fragment of SFO and give a pastification procedure that transforms bounded-response SFO formulas into equisatisfiable formulas in this fragment. We then develop an efficient runtime monitoring algorithm for this past-time fragment and evaluate its performance on a set of benchmarks, demonstrating the practicality and effectiveness of our approach. To the best of our knowledge, this is the first publicly available prototype for online quantitative monitoring of full SFO.","lang":"eng"}],"page":"214-233","file":[{"checksum":"7055199ecb985e9e2e272f4988827067","access_level":"open_access","success":1,"date_created":"2026-06-22T08:18:41Z","relation":"main_file","content_type":"application/pdf","file_name":"2026_LNCS_Chalupa.pdf","creator":"dernst","file_size":849237,"file_id":"22113","date_updated":"2026-06-22T08:18:41Z"}],"file_date_updated":"2026-06-22T08:18:41Z","keyword":["Signal first-order logic","Robustness-based quantitative semantics","Online runtime monitoring"],"OA_type":"hybrid","article_processing_charge":"No","title":"Quantitative monitoring of Signal First-Order logic","arxiv":1,"oa_version":"Published Version","date_created":"2026-06-14T22:01:44Z","publication_status":"published"},{"year":"2026","PlanS_conform":"1","OA_place":"publisher","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","das_tickbox":"1","_id":"22100","date_updated":"2026-06-24T06:10:44Z","publication_identifier":{"eissn":["2399-3650"]},"month":"04","language":[{"iso":"eng"}],"quality_controlled":"1","intvolume":"         9","publication":"Communications Physics","acknowledgement":"J.-L.Li thanks Gaoren Wang for valuable discussions on the absorbing boundary condition.

Combining them with strong, long-range dipolar interactions provides highly flexible control schemes promising even more exotic quantum phases. Recently, microwave shielding gave access to spin-polarized degenerate samples of dipolar fermionic molecules, where tunable p-wave interactions were enabled by field-linked resonances available only by compromising the shielding (due to experimental limitations). Here, we study the scattering properties of a fermionic dipolar spin mixture and show that a universal s-wave resonance is readily accessible without compromising the shielding. We develop a universal description of the tunable s-wave interaction and weakly bound tetratomic states based on the microwave-field parameters. The s-wave resonance paves the way to stable, controllable and strongly-interacting dipolar spin mixtures of deeply degenerate fermions and supports favorable conditions to reach this regime via evaporative cooling."}],"oa_version":"Published Version","date_created":"2026-06-21T22:02:58Z","publication_status":"published","title":"Tunable field-linked s-wave interactions in dipolar fermi mixtures","article_processing_charge":"Yes","arxiv":1,"OA_type":"gold"},{"status":"public","has_accepted_license":"1","scopus_import":"1","oa":1,"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"corr_author":"1","author":[{"last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu"},{"full_name":"Kafshdar Goharshadi, Ehsan","orcid":"0000-0002-8595-0587","last_name":"Kafshdar Goharshadi","id":"103b4fa0-896a-11ed-bdf8-87b697bef40d","first_name":"Ehsan"},{"last_name":"Zikelic","first_name":"Dorde","id":"294AA7A6-F248-11E8-B48F-1D18A9856A87","full_name":"Zikelic, Dorde","orcid":"0000-0002-4681-1699"}],"project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","grant_number":"863818","call_identifier":"H2020","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E"}],"department":[{"_id":"KrCh"}],"publisher":"Association for Computing Machinery","supplementarymaterial":"no","file":[{"date_updated":"2026-06-24T06:19:56Z","file_id":"22135","file_size":858595,"creator":"dernst","file_name":"2026_ProcACMProgrammingLanguages_Chatterjee.pdf","relation":"main_file","content_type":"application/pdf","success":1,"date_created":"2026-06-24T06:19:56Z","access_level":"open_access","checksum":"994bf21d6269dabccf1e1091e02962c5"}],"external_id":{"arxiv":["2603.26215"]},"abstract":[{"text":"Differential privacy (DP) has established itself as one of the standards for ensuring privacy of individual data. However, reasoning about DP is a challenging and error-prone task, hence methods for formal verification and refutation of DP properties have received significant interest in recent years. In this work, we present a novel method for automated formal refutation of є-DP. Our method refutes є-DP by searching for a pair of inputs together with a non-negative function over outputs whose expected value on these two inputs differs by a significant amount. The two inputs and the non-negative function over outputs are computed simultaneously, by utilizing upper expectation supermartingales and lower expectation submartingales from probabilistic program analysis, which we leverage to introduce a sound and complete proof rule for є-DP refutation. To the best of our knowledge, our method is the first method for є-DP refutation to offer the following four desirable features: (1) it is fully automated, (2) it is applicable to stochastic mechanisms with sampling instructions from both discrete and continuous distributions, (3) it provides soundness guarantees, and (4) it provides semi-completeness guarantees. Our experiments show that our prototype tool SuperDP achieves superior performance compared to the state of the art and manages to refute є-DP for a number of challenging examples collected from the literature, including ones that were out of the reach of prior methods.","lang":"eng"}],"keyword":["Static Program Analysis","Differential Privacy","Probabilistic Programming","Martingales"],"dataavailabilitystatement":"The artifact supporting the findings of this study, which includes the underlying datasets, software\r\ncode, and experiments, is publicly available in Zenodo https://zenodo.org/records/19399862.","file_date_updated":"2026-06-24T06:19:56Z","article_type":"original","issue":"PLDI","OA_type":"gold","oa_version":"Published Version","publication_status":"published","related_material":{"record":[{"id":"22134","relation":"research_data","status":"public"}]},"date_created":"2026-06-21T22:02:59Z","arxiv":1,"title":"SuperDP: Differential privacy refutation via supermartingales","article_processing_charge":"Yes","_id":"22102","das_tickbox":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2026-06-24T06:39:37Z","year":"2026","OA_place":"publisher","PlanS_conform":"1","month":"06","ec_funded":1,"publication_identifier":{"eissn":["2475-1421"]},"volume":10,"ddc":["000"],"type":"journal_article","citation":{"ista":"Chatterjee K, Goharshady E, Zikelic D. 2026.

Diptera have undergone multiple sex-chromosome turnovers and expansions while maintaining their general chromosomal content, which makes them an ideal clade to study such transitions. We analysed more than 100 dipteran whole-genome assemblies and identified 4 new lineages that underwent sex-chromosome turnover (in addition to the 5 previously reported). We find the majority of turnovers happened in the group Schizophora, which tend to have fewer genes on the F element (the chromosome homologous to the ancestral insect X chromosome) than lower dipterans, a factor previously hypothesized to facilitate turnover. Most derived X chromosomes have higher GC content than autosomes, consistent with a high prevalence of male-achiasmy in Diptera. In addition, an excess of gene movement out of the X is detected for most of these new X chromosomes, and many of these moved genes have high testis expression in Drosophila, suggesting that out-of-X gene movement contributes to the long-term demasculinization of X chromosomes."}],"oa_version":"Published Version","date_published":"2026-01-08T00:00:00Z","date_created":"2025-12-17T10:10:57Z","day":"8","article_processing_charge":"No","title":"Research Data for 'Causes and consequences of sex-chromosome turnovers in Diptera'","doi":"10.15479/AT-ISTA-20833"},{"doi":"10.1038/s42005-026-02514-w","DOAJ_listed":"1","date_published":"2026-03-04T00:00:00Z","article_number":"80","day":"04","volume":9,"ddc":["530"],"type":"journal_article","citation":{"ieee":"S.

Here, after refining a figure-of-merit for the problem, we present a 1-milligram torsional pendulum operating at 18 Hz. We demonstrate laser cooling its motion from room temperature to 240 microkelvins, surpassing by over 20-fold the coldest motions attained for oscillators ranging from micrograms to kilograms. We quantify and contrast the utility of the current approach with other platforms. The achieved performance and large improvement potential highlight milligram-scale torsional pendulums as a powerful platform for precision measurements relevant to future studies at the quantum-gravity interface.","lang":"eng"}],"file_date_updated":"2026-03-16T10:07:46Z","article_type":"original","author":[{"id":"09501ff6-dca7-11ea-a8ae-b3e0b9166e80","first_name":"Sofya","last_name":"Agafonova","full_name":"Agafonova, Sofya","orcid":"0000-0003-0582-2946"},{"last_name":"Rosello","first_name":"Pere","full_name":"Rosello, Pere"},{"full_name":"Mekonnen, Manuel","last_name":"Mekonnen","first_name":"Manuel"},{"first_name":"Onur","id":"4C02D85E-F248-11E8-B48F-1D18A9856A87","last_name":"Hosten","orcid":"0000-0002-2031-204X","full_name":"Hosten, Onur"}],"corr_author":"1","project":[{"_id":"bdb2a702-d553-11ed-ba76-f12e3e5a3bc6","grant_number":"101087907","name":"A quantum hybrid of atoms and milligram-scale pendulums: towards gravitational quantum mechanics"}],"publisher":"Springer Nature","department":[{"_id":"GradSch"},{"_id":"OnHo"}],"has_accepted_license":"1","status":"public","scopus_import":"1","oa":1,"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"}},{"publication_identifier":{"eissn":["1432-0835"],"issn":["0944-2669"]},"month":"01","OA_place":"publisher","PlanS_conform":"1","year":"2026","date_updated":"2026-04-07T08:37:46Z","_id":"20865","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","day":"01","date_published":"2026-01-01T00:00:00Z","article_number":"23","doi":"10.1007/s00526-025-03193-1","publication":"Calculus of Variations and Partial Differential Equations","acknowledgement":"The author would like to thank Jan Maas for suggesting this project and for many helpful comments, Antonio Agresti, Lorenzo Dello Schiavo and Julian Fischer for several fruitful discussions, Oliver Tse for pointing out the reference [10], and the anonymous reviewer for carefully reading this manuscript and providing valuable suggestions.

We work under mild assumptions on the domain,\r\nthe drift, and the initial datum.

Our discrete scheme and modified\r\ndistance draw inspiration from contributions by A. Figalli and N. Gigli [J. Math. Pures\r\nAppl. 94, (2010), pp. 107–130], and J. Morales [J. Math. Pures Appl. 112, (2018), pp. 41–88]\r\non an optimal-transport approach to evolution equations with Dirichlet boundary conditions.\r\nSimilarly to these works, we allow the mass to flow from/to the boundary ∂Ω throughout\r\nthe evolution. However, our leading idea is to also keep track of the mass at the boundary\r\nby working with measures defined on the whole closure Ω . The driving functional is a\r\nmodification of the classical relative entropy that also makes use of the information at the\r\nboundary. As an intermediate result, when Ω is an interval in R1, we find a formula for the\r\ndescending slope of this geodesically nonconvex functional."}],"external_id":{"arxiv":["2403.07803"]},"file":[{"date_updated":"2026-01-05T12:36:39Z","file_id":"20945","file_size":958382,"content_type":"application/pdf","file_name":"2026_CalculusVariations_Quattrocchi.pdf","relation":"main_file","creator":"dernst","access_level":"open_access","success":1,"date_created":"2026-01-05T12:36:39Z","checksum":"635370d64abaf444f50f5cca60bba1be"}]},{"_id":"20964","supervisor":[{"first_name":"Jiří","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","orcid":"0000-0002-8302-7596","full_name":"Friml, Jiří"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","date_updated":"2026-04-07T11:41:44Z","year":"2026","OA_place":"publisher","month":"01","acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"}],"publication_identifier":{"issn":["2791-4585"]},"ddc":["570"],"type":"dissertation","citation":{"apa":"Vladimirtsev, D.

A new parametrization has demonstrated that the damping wing signature also carries local information about the distribution of neutral hydrogen (H I) in front of the quasar before it started shining. Leveraging a recently introduced Bayesian JAX-based Hamiltonian Monte Carlo inference framework, we derive constraints on the Lorentzian-weighted H I column density NDW H I , the quasar’s distance rpatch to the first neutral patch, and its lifetime tQ based on James Webb Space\r\nTelescope (JWST) Near Infrared Spectrograph (NIRSpec) spectra of the two z ∼ 7.5 quasars J1007+2115 and J1342+0928. After folding in model-dependent topology information, we find that J1007+2115 (and J1342+0928) is most likely to reside in a (xH1)= 0.32+0.22 −0.20 (0.58+0.23 −0.23) neutral IGM while shining for a remarkably short lifetime of log10 tQ/yr = 4.14+0.74 −0.18 (an intermediate lifetime of 5.64+0.25 −0.43) along a sightline with log10 NDW\r\nH I /cm−2 = 19.70+0.35 −0.86 (20.24+0.25 −0.22) and rpatch = 28.9+54.0 −14.4 cMpc\r\n(10.9+5.6−5.9 cMpc).

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.","lang":"eng"}]},{"doi":"10.15479/AT-ISTA-20991","day":"16","date_published":"2026-01-16T00:00:00Z","citation":{"ieee":"D. F.

The evolutionary success of these populations is fundamentally dictated by the organization of genetic variation—the genomic architecture—in the face of severe demographic constraints, such as the founder effects and genetic bottlenecks that frequently accompany colonization. A central question in evolutionary biology is whether rapid adaptation relies on major-effect loci, such as chromosomal inversions, or on many small-effect loci dispersed across the genome. Furthermore, the genomic architecture strongly influences the extent to which evolutionary outcomes are predictable. Using introduced populations of the marine snail, Littorina saxatilis, as a model, this thesis investigates how genetic variation and genomic structure drive adaptation following introduction. We employed a population genomics approach on experimentally and accidentally introduced populations to dissect the specific genomic features that underpin divergence in newly colonized environments.\r\n\r\nIn Chapter 2, we tested the predictability of local adaptation through an uncommon 30-year transplant experiment in nature. By distinguishing allele and chromosomal inversion frequency changes from neutral expectations, we found that evolutionary change was highly predictable at the macro-scale (phenotypes and chromosomal inversions), but less robust at the level of individual collinear loci. This result demonstrates that evolution can be predictable when a population possesses sufficient standing genetic variation (SGV), with chromosomal inversions acting as key integrated units that facilitate a rapid response to selection. Building on this, Chapter 3 applied whole-genome sequencing to three accidentally introduced populations (Venice, San Francisco, and Redwood City) to investigate their likely source and genomic patterns of divergence. We identified genomic regions of remarkable divergence potentially associated with local adaptation, and likely fuelled by SGV, while explicitly acknowledging the difficulty in disentangling selection signals from the genome-wide effects of demographic processes. Furthermore, we found that the divergence patterns relied extensively on the collinear genome in these introduced populations, and less clearly on the chromosomal inversions. This observation contrasts with local adaptation observed in the experimental system that relied on both collinear loci and highly selected chromosomal inversions, highlighting how demographic history and genomic architecture influence the detectable signature of local adaptation.\r\n\r\nA major limitation to conducting large-scale comparative evolutionary studies is the lack of data standardization, which prevents the integration of community knowledge and high-resolution environmental and genetic data. Chapter 4 addresses this by developing a community database for the Littorina system. This platform implements standardized protocols for the integration of diverse phenotypic and environmental data from multiple Littorina species. Likewise, the platform also centralizes the availability of associated genomic data through links to external repositories. This database represents a crucial tool to test complex, large-scale evolutionary hypotheses.\r\n\r\nCollectively, this thesis strongly reinforces the fundamental importance of SGV as the raw material for successful local adaptation, a conclusion supported by evidence in both experimental and accidental introductions. Furthermore, this work highlights the critical role of the genomic architecture—specifically chromosomal inversions—in driving the predictability and effectiveness of adaptive responses. Our findings underscore how the interplay between SGV and genomic architecture dictates the trajectory and detectability of evolution in colonizing populations, while simultaneously providing a necessary tool to advance comparative evolutionary genomics in emerging model organisms.","lang":"eng"}],"page":"199","license":"https://creativecommons.org/licenses/by-nc-sa/4.0/","file":[{"date_updated":"2026-01-16T12:25:13Z","file_size":22456421,"file_id":"20996","creator":"dgarciac","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","relation":"source_file","file_name":"2026_Garcia_Diego_Thesis.docx","checksum":"841f1bc073d667125729b2a017f8c37a","date_created":"2026-01-16T12:25:13Z","access_level":"closed"},{"date_updated":"2026-01-16T12:25:13Z","file_id":"20997","file_size":9556719,"creator":"dgarciac","content_type":"application/pdf","file_name":"2026_Garcia_Diego_Thesis.pdf","relation":"main_file","date_created":"2026-01-16T12:25:13Z","success":1,"access_level":"open_access","checksum":"a1f33d4f183ce7072eee42a6ccf5340b"},{"date_updated":"2026-01-16T13:08:14Z","description":"Source code of the PostgreSQL database, front-end and back-end of the LittorinaDB web application developed as a product of the 4th chapter of the thesis.","file_size":54491433,"file_id":"20998","file_name":"2026_DiegoGarcia_LittorinaDB Source Code and Protocols.rar","content_type":"application/x-compressed","relation":"supplementary_material","creator":"dgarciac","checksum":"98a80691067174c30fe53f38ce7344e6","access_level":"closed","date_created":"2026-01-16T13:08:14Z"},{"relation":"supplementary_material","content_type":"application/x-compressed","file_name":"2026_DiegoGarcia_Thesis-Supplementary_Material.rar","creator":"dgarciac","access_level":"open_access","date_created":"2026-01-16T13:08:14Z","checksum":"99a3cab2fa36666b9a92eefc27d586da","date_updated":"2026-01-16T13:08:14Z","file_id":"20999","file_size":7982811},{"creator":"dgarciac","file_name":"README.txt","relation":"supplementary_material","content_type":"text/plain","date_created":"2026-01-16T13:08:59Z","access_level":"open_access","checksum":"255fdf56b2932c46bf27c63aa6106a4f","date_updated":"2026-01-16T13:08:59Z","file_id":"21000","file_size":732}],"file_date_updated":"2026-01-16T13:08:59Z","degree_awarded":"PhD","alternative_title":["ISTA Thesis"],"author":[{"full_name":"Garcia Castillo, Diego Fernando","id":"ae681a14-dc74-11ea-a0a7-c6ef18161701","first_name":"Diego Fernando","last_name":"Garcia Castillo"}],"corr_author":"1","department":[{"_id":"GradSch"},{"_id":"NiBa"}],"publisher":"Institute of Science and Technology Austria","has_accepted_license":"1","status":"public","tmp":{"short":"CC BY-NC-SA (4.0)","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","image":"/images/cc_by_nc_sa.png"},"oa":1}]
