Applied strain has attracted particular attention as a key tuning parameter for altermagnets. Although several experimental studies have demonstrated the preparation of single-domain states through a combination of applied strain and magnetic field, the route to such states remains unclear. Here, we use magneto-optical measurements on single crystals of MnTe under applied strain to show that, in contrast to previous reports, strain acts primarily to rotate the Néel vector L continuously. Since the orientation of L determines the magnetic point group symmetry, this continuous rotation effectively tunes the symmetry and its associated physical properties. Furthermore, we demonstrate that built-in strain in free-standing crystals is sufficient to pin L into continuous textures over millimeter length scales. Together, these results provide guidance for future device design and open the door to leveraging the Néel vector orientation as a tunable degree of freedom in spintronic applications.","lang":"eng"}],"day":"08"},{"oa_version":"Published Version","OA_type":"hybrid","oa":1,"file_date_updated":"2026-05-04T06:46:31Z","file":[{"success":1,"file_id":"21783","file_name":"2026_PNAS_Isakova.pdf","date_created":"2026-05-04T06:46:31Z","relation":"main_file","access_level":"open_access","checksum":"11b7a13a359e302498b2367906093a6b","date_updated":"2026-05-04T06:46:31Z","file_size":3355016,"creator":"dernst","content_type":"application/pdf"}],"day":"07","article_processing_charge":"Yes (in subscription journal)","volume":123,"date_updated":"2026-05-04T06:57:31Z","doi":"10.1073/pnas.2532018123","publication_status":"published","status":"public","ddc":["570"],"publication":"Proceedings of the National Academy of Sciences","month":"04","external_id":{"pmid":["41915737"]},"citation":{"ieee":"L.

However, this question is understudied in part because experimental and computational studies use extant sequences as a starting point to study sequence space. Here, we study whether extant sequences are representative of the entire functional sequence space. Across thousands of protein families from vertebrates and bacteria we calculate the dimensionality and the volume of sequence space occupied by extant homologs. We find that the observed dimensionality and volume of extant sequence space are minuscule, many orders of magnitude smaller than what we estimated using a model of protein evolution. Simulating sequence evolution we then quantify the impact of phylogeny, selection, and epistasis on restricting the evolutionary exploration of sequence space. We find that sequence evolution from a single common ancestor, or a single point of origin in sequence space, is by far the largest limiting factor that reduces the dimensionality and volume of extant sequence space. These results indicate that there are vast areas of functional sequence space that have not been explored in evolution because of the excessive restrictions on natural exploration of the protein sequence space imposed by the point of origin effect. We suggest that protein design methods that rely on extant sequences may be limited in their ability to discover truly novel functions.","lang":"eng"}],"publication_identifier":{"eissn":["1091-6490"]},"type":"journal_article","license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","title":"Descent from a common ancestor restricts exploration of protein sequence space","acknowledgement":"We thank Olga Kalinina for feedback on our manuscript, Vsevolod Kuksin for fruitful discussions and Lev Tsarin for participation in the design of our models.

Follow-up with the Large Lenslet Array Magellan Spectrograph shows a helium-dominated accretion disk, and high-speed ULTRACAM photometry reveals pronounced primary and secondary eclipses. We construct a decade-long timing baseline leveraging light curves from the ATLAS and Gaia surveys, as well as the high-speed imagers ULTRACAM on the New Energy Telescope and proto-Lightspeed on the Magellan Clay telescope. From this timing baseline, we measure an orbital period derivative of P 1.60 0.07 10 = ± × 12 s s−1. Interpreted in the context of stable mass transfer, the magnitude and sign of P indicate that the orbital evolution is governed by the interplay between gravitationalwave-driven angular-momentum losses and mass transfer, directly probing the donor’s structural response to mass loss. We constrain the accretor and donor mass based on stable mass-transfer arguments assuming angularmomentum loss dominated by gravitational-wave emission, allowing us to infer the characteristic gravitational\r\nwave strain of the binary for future space-based GW observatories such as the Laser Interferometer Space Antenna (LISA). We predict a characteristic strain corresponding to a 4 yr LISA signal-to-noise ratio ≳10, establishing ATLAS J1013−4516 as a strong prospective LISA source that will probe long-term orbital evolution in the mass-transferring regime."}],"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"arxiv":1,"license":"https://creativecommons.org/licenses/by/4.0/","type":"journal_article","title":"An eclipsing 8.56 minutes orbital period mass-transferring binary","publication":"The Astrophysical Journal","month":"04","external_id":{"arxiv":["2601.07925"]},"year":"2026","citation":{"ieee":"E.

How neuronal left-right asymmetry is initiated and integrated into a bilaterally symmetrical ground pattern is poorly understood. Here, we show that the directional asymmetry of a Drosophila central brain circuit originates from axonal interactions of two types of bilateral pioneer neurons. Subsequent recruitment of neighboring neurons into the asymmetric neuropil primordium results in hemisphere-specific microcircuits. Circuit lateralization requires dynamic expression of the cell adhesion molecule Fasciclin 2 to maintain structural plasticity in axonal remodeling. Reduced circuit asymmetry following cell type–specific Fasciclin 2 manipulation affects adult brain function. These results reveal an unexpected degree of developmental plasticity of late-born Drosophila neurons in the formation of a circuit node via the lateralized recruitment of symmetric circuit components.","lang":"eng"}],"quality_controlled":"1","author":[{"full_name":"Markovitsch, Johann W.","first_name":"Johann W.","last_name":"Markovitsch"},{"full_name":"Mitić, Daniel","first_name":"Daniel","last_name":"Mitić"},{"first_name":"Alisa","last_name":"Del Pilar Jiménez García","full_name":"Del Pilar Jiménez García, Alisa"},{"full_name":"Zane, Alsberga","orcid":"0009-0003-0415-7603","id":"60f7509a-f652-11ea-9d86-b963d6490d7c","first_name":"Alsberga","last_name":"Zane"},{"full_name":"Kainz, Sarah","first_name":"Sarah","last_name":"Kainz"},{"last_name":"Kaur","first_name":"Rashmit","full_name":"Kaur, Rashmit"},{"last_name":"Hummel","first_name":"Thomas","full_name":"Hummel, Thomas"}],"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"},"department":[{"_id":"MiSi"},{"_id":"GradSch"}],"article_type":"original","publisher":"American Association for the Advancement of Science","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_number":"eaea6020","intvolume":"        12","_id":"21707","date_published":"2026-03-27T00:00:00Z","acknowledgement":"We thank I.

The GLOF also destroyed 13 bridges and a major hydropower plant in the Chungthang region. Over 60,000 individuals in four districts of Sikkim were impacted by this GLOF event. This study examines the factors that led to the GLOF event. Our study shows that the cause of this GLOF was initiated by a landslide, that dumped a substantial amount (~ 38.31 million m3) of debris into the South Lhonak Lake. Furthermore, the glacier that was connected to the lake, lost a big chunk of ice mass (~ 7 million m3) due to calving. The combination of these two processes led to the collapse of the left lateral moraine that consequently generated flood waves which breached the terminal moraine dam of the lake. We recommend monitoring land subsidence and calving events for large proglacial lakes to prevent the disastrous consequences of such GLOFs in the future."}],"quality_controlled":"1","author":[{"last_name":"Mohanty","first_name":"Litan Kumar","full_name":"Mohanty, Litan Kumar"},{"full_name":"Gantayat, Prateek","last_name":"Gantayat","id":"02734268-3e8d-11ef-80a1-cec4a088d004","first_name":"Prateek"},{"full_name":"Dixit, Ankur","last_name":"Dixit","first_name":"Ankur"},{"full_name":"Das Adhikari, Manik","first_name":"Manik","last_name":"Das Adhikari"},{"full_name":"Biswas, Rahul","first_name":"Rahul","last_name":"Biswas"},{"last_name":"Singh","first_name":"Vivek Kumar","full_name":"Singh, Vivek Kumar"}],"department":[{"_id":"FrPe"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"}},{"scopus_import":"1","issue":"1","date_created":"2026-04-12T22:01:48Z","OA_place":"publisher","acknowledgement":"We would like to thank the anonymous reviewer for their constructive comments, which improved the final manuscript.\r\n\r\nWe thank Bernd Husemann for his critical contributions to the NIRSpec Wide GTO survey, and in particular his help in selecting high-priority X-ray-luminous targets.\r\n\r\nR.E.H. acknowledges support by the German Aerospace Center (DLR) and the Federal Ministry for Economic Affairs and Energy (BMWi) through program 50OR2403 “RUBIES.” A.d.G. acknowledges support from a Clay Fellowship awarded by the Smithsonian Astrophysical Observatory.

Key questions are how LRDs connect to standard UV-luminous AGN, whether transitional phases exist, and whether they are observable. We present the “X-ray dot” (XRD), a compact source at z = 3.28 observed by the NIRSpec Wide Guaranteed Time Observation survey. The XRD exhibits LRD hallmarks: a blackbody-like (Teff ≃ 6400 K) red continuum, a faint but blue rest-UV excess, falling mid-IR emission, and broad Balmer lines (FWHM ∼ 2700–3200 km s−1). Unlike LRDs, however, it is remarkably X-ray luminous (L2−10 keV = 1044.18 erg s−1) and has a continuum inflection that is blueward of the Balmer limit. We find that the red rest-optical and blue mid-IR continuum cannot be reproduced by standard dust-attenuated AGN models without invoking extremely steep extinction curves, nor can the weak mid-IR emission be reconciled with well-established X-ray–torus scaling relations. We therefore consider an alternative scenario: the XRD may be an LRD in transition, where the gas envelope dominates the optical continuum but optically thin sight lines allow X-rays to escape. The XRD may thus provide a physical link between LRDs and standard AGN, offering direct evidence that LRDs are powered by supermassive black holes and providing insight into their accretion properties.","lang":"eng"}],"publication_identifier":{"issn":["2041-8205"],"eissn":["2041-8213"]},"arxiv":1,"type":"journal_article","title":"The X-ray dot: Exotic dust or a late-stage Little Red Dot?","publication":"The Astrophysical Journal Letters","month":"03","external_id":{"arxiv":["2601.09778"]},"year":"2026","citation":{"chicago":"Hviding, Raphael E., Anna De Graaff, Hanpu Liu, Andy D.

We study this problem using JWST imaging and prism spectroscopy for 412 galaxies at 4.5 < z < 9.0. We fit these data simultaneously with stellar population and nebular emission models that include a parameter for the fraction of ionizing photons that escape the galaxy, fesc. We find that the ionization production efficiency, ξion = Q(H0)/LUV, increases with redshift and decreasing UV luminosity, but shows significant scatter, (log ion z, MUV) 0.3 dex. The inferred escape fractions averaged over the population are low, ranging from〈fesc〉 ≃ 2.6% ± 1.4% at 6 < z < 9 to 6.5% ± 2.2% at 4.5 < z < 6, with weak or no indication of evolution with redshift. This implies that in our models most of the ionizing photons need to be absorbed to account for the nebular emission. We compute the impact of our results on reionization, including the distributions for ξion and fesc, and the evolution and uncertainty of the UV luminosity function. Considering galaxies brighter than MUV < −16 mag would produce an intergalactic medium hydrogen-ionized fraction of xe = 0.5 at 5.3 < z < 5.8, possibly too late compared to constraints from from quasistellar\r\nobject (QSO) sight lines. Including fainter galaxies, MUV < −14 mag, we obtain xe = 0.5 at 6.0 < z < 8.1, fully consistent with QSO and cosmic microwave background data. This implies that EoR galaxies produce plenty of ionizing photons, but that these do not efficiently escape. This may be a result of high gas column densities combined with burstier star formation histories, which limit the time massive stars are able to clear channels through the gas for ionizing photons to escape.","lang":"eng"}],"quality_controlled":"1","article_type":"original","publisher":"IOP Publishing","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","acknowledgement":"We wish to thank our colleagues in the CEERS collaboration for their hard work and valuable contributions on this project.

They enable higher sample loading, improve chromatographic performance, and protect the analytical column by removing salts and contaminants. Recently, monolithic trap columns with micropillar architecture have emerged as alternatives to conventionally packed traps. This study compares the performance of a packed and a micropillar monolithic trap column for the analysis of tryptic peptides. Methods: A tryptic digest of HeLa cell lysate was analyzed under identical LC–MS conditions using both trap types. Peptides were detected at 214 nm and analyzed by nano-ESI on a Q Exactive Plus Orbitrap. Data were searched against the human UniProt database (February 2023) using FragPipe v20.0, and statistical evaluation of MaxLFQ intensities was performed in Perseus using Welch’s t-test and clustering analysis. Results: Over 2500 proteins were identified with both setups. The packed trap column yielded more total peptides, particularly those with post-translational modifications and higher hydrophilicity, whereas the monolithic column favored peptides of intermediate hydrophobicity. Chromatographic profiles confirmed a slight reduction in the trapping efficiency of hydrophilic peptides by the monolithic trap. Conclusions: Trap column design significantly influences peptide recovery and proteome coverage."}],"type":"journal_article","publication_identifier":{"eissn":["2227-7382"]},"title":"Comparison of the trapping efficiency for tryptic peptides on particle-packed and micro-pillar trap columns for proteomics analyses"},{"year":"2026","citation":{"ista":"Lin A, Charisi M, Haiman Z. 2026.

At subparsec separations, SMBHBs can be identified as quasars with periodic variability, with previous periodicity searches uncovering significant candidates. However, these searches focused primarily on sinusoidal signals, while theoretical models and hydrodynamical simulations predict that binaries produce more complex non-sinusoidal pulse shapes. Here we examine the efficacy of the Lomb–Scargle periodogram (LSP; one of the most popular tools for periodicity searches in unevenly sampled lightcurves) to detect periodicities with a sawtooth shape mimicking results of hydrodynamical simulations. We simulate idealized well-sampled lightcurves, lightcurves that mimic the data in the Palomar Transient Factory (PTF) analyzed in M. Charisi et al. (2016), and lightcurves that resemble our expectations for single-band data in the upcoming Legacy Survey of Space and Time (LSST) of the Rubin Observatory. We approximate quasar variability with a damped random walk (DRW) model, inject sinusoidal and sawtooth pulse shapes, and assess their statistical significance. We find that in the presence of red noise, the LSP detects a relatively low fraction of the sinusoidal signals (∼45%, ∼24%, and ∼23%, in the PTF-like, idealized, and LSST-like lightcurves, respectively). The fraction is significantly reduced for sawtooth periodicity (with only ∼9% in PTF-like and ∼1% in idealized and LSST-like lightcurves). These low recovery rates imply that previous searches have missed the large majority of binaries. They also have significant implications for the detection of SMBHBs in upcoming LSST necessitating the development of advanced tools that go beyond the simple LSP.","lang":"eng"}]},{"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"},"department":[{"_id":"ZoHa"}],"author":[{"last_name":"Bartos","first_name":"Imre","full_name":"Bartos, Imre"},{"orcid":"0000-0003-3633-5403","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","first_name":"Zoltán","last_name":"Haiman","full_name":"Haiman, Zoltán"}],"abstract":[{"text":"GW231123 represents the most massive binary–black hole merger detected to date, lying firmly within, or even above, the pair-instability mass gap. The component spins are both exceptionally high (a1 = 0.90 +0.10/-0.19, a2 = 0.80 +0.20/-0.51), which is difficult to explain with repeated mergers. Here we show that the black hole spin vectors are closely aligned with each other while significantly tilted relative to the binary’s orbital angular momentum, pointing to a common accretion-driven origin. We examine astrophysical formation channels capable of producing near-equal, high-mass, and mutually aligned spins consistent with GW231123—particularly binaries embedded in AGN disks and Population III remnants, which grew via coherent misaligned gas accretion. We further argue that other high-mass, high-spin events, e.g., GW190521, may share a similar evolutionary pathway. These findings underscore the critical role of sustained, coherent accretion in shaping the most extreme black hole binaries.","lang":"eng"}],"quality_controlled":"1","corr_author":"1","type":"journal_article","publication_identifier":{"issn":["2041-8205"],"eissn":["2041-8213"]},"arxiv":1,"title":"Accretion is all you need: Black Hole spin alignment in merger GW231123 indicates accretion pathway","OA_place":"publisher","date_created":"2026-04-12T22:01:49Z","issue":"2","scopus_import":"1","language":[{"iso":"eng"}],"acknowledgement":"The authors thank Davide Gerosa and Matthew Mould for valuable suggestions.

In this Letter, we propose a new formation scenario for black hole (BH) + Be star binaries (hereafter BHBe binaries), where the Be star is produced through the wind Roche lobe overflow (WRLOF) mechanism. Our analysis is based on numerical simulations of the WRLOF process in massive binaries, building on recent theoretical work. We demonstrate that the WRLOF model can efficiently form BHBe binaries under reasonable assumptions on stellar wind velocities. Using rapid binary population synthesis, we estimate the population of such systems in the Milky Way, predicting ∼1800−3200 currently existing BHBe binaries originating from the WRLOF channel. These systems are characterized by high eccentricities and exceptionally wide orbits, with typical orbital periods exceeding 1000 days and a peak distribution around ∼10,000 days. Due to their long orbital separations, these BHBe binaries are promising targets for future detection via astrometric and interferometric observations."}],"author":[{"first_name":"Zhenwei","last_name":"Li","full_name":"Li, Zhenwei"},{"first_name":"Shi","last_name":"Jia","full_name":"Jia, Shi"},{"id":"5dd129bd-0601-11ef-b325-833284687b76","first_name":"Dandan","last_name":"Wei","full_name":"Wei, Dandan"},{"last_name":"Ge","first_name":"Hongwei","full_name":"Ge, Hongwei"},{"last_name":"Chen","first_name":"Hailiang","full_name":"Chen, Hailiang"},{"full_name":"Zhang, Yangyang","first_name":"Yangyang","last_name":"Zhang"},{"first_name":"Xuefei","last_name":"Chen","full_name":"Chen, Xuefei"},{"last_name":"Han","first_name":"Zhanwen","full_name":"Han, Zhanwen"}],"department":[{"_id":"YlGo"}],"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"},"title":"Formation of Be stars via wind accretion: Case study on Black Hole + Be star binaries","type":"journal_article","arxiv":1,"publication_identifier":{"issn":["2041-8205"],"eissn":["2041-8213"]},"intvolume":"       996","_id":"21714","article_number":"L42","date_published":"2026-01-10T00:00:00Z","language":[{"iso":"eng"}],"acknowledgement":"We are deeply grateful to the anonymous referee for the insightful comments, which have significantly improved the quality of this work.

Leveraging X-ray through far-infrared observations of two of the most luminous known little red dots, we directly measure their bolometric luminosities. We find evidence that more than half of the bolometric luminosity likely emerges in the rest-frame optical, with Lbol/L5100 = 5, roughly half the value for “standard” active galactic nuclei. Meanwhile, the X-ray emitting corona, UV-emitting blackbody, and reprocessed mid to far-infrared emission are all considerably subdominant, assuming that the far-infrared luminosity is well below current measured limits. We present new bolometric corrections that dramatically lower inferred bolometric luminosities by a factor of 10 compared to published values in the literature. These bolometric corrections are in accord with expectations from models in which gas absorption and reprocessing are responsible for the red rest-frame optical colors of little red dots. We discuss how this lowered luminosity scale suggests a lower mass scale for the population by at least an order of magnitude (e.g., ∼105–107 M⊙ black holes, and ∼108 M⊙ galaxies), alleviating tensions with clustering, overmassive black holes, and the integrated black hole mass density in the Universe.","lang":"eng"}],"quality_controlled":"1","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"arxiv":1,"type":"journal_article","title":"What you see is what you get: Empirically measured bolometric luminosities of Little Red Dots","scopus_import":"1","date_created":"2026-04-12T22:01:50Z","issue":"2","OA_place":"publisher","acknowledgement":"We benefit from the following JWST programs: UNCOVER (JWST/GO #2561; Labbé & Bezanson); ALT (JWST-GO #3516; Naidu & Matthee); MegaScience (JWST-GO #4111; Suess); RUBIES (JWST-GO #4233; de Graaff & Brammer); PRIMER (JWST/GO #1837; Dunlop).\r\n\r\nWe acknowledge funding from NSF/AAG #2306950, JWST-GO-02561, JWST-GO-03516, and JWST-GO-04111, provided through a grant from the STScI under NASA contract NAS5-03127.

This review synthesizes current knowledge on how heat stress disrupts microsporogenesis and microgametogenesis, and how plants counteract these stresses through diverse thermotolerance mechanisms. We emphasize temperature-sensitive processes, including meiotic progression in male germ cells, programmed cell death of somatic tapetal nurse cells, and post-meiotic pollen tube development. We further discuss how epigenetic regulators enhance thermotolerance by reprogramming DNA methylation landscapes and modulating histone variant distribution.

An objective is a set of runs (or infinite trajectories) of the RMDP, and the value for an objective is the maximal probability that the agent can guarantee against the adversarial environment. We consider (a) reachability objectives, where given a target set of states, the goal is to eventually arrive at one of them; and (b) parity objectives, which are a canonical representation for ω-regular objectives. The qualitative analysis problem asks whether the objective can be ensured with probability 1. In this work, we study the qualitative problem for reachability and parity objectives on RMDPs without making any assumption over the structures of the RMDPs, e.g., unichain or aperiodic. Our contributions are twofold. We first present efficient algorithms with oracle access to uncertainty sets that solve qualitative problems of reachability and parity objectives. We then report experimental results demonstrating the effectiveness of our oracle-based approach on classical RMDP examples from the literature scaling up to thousands of states."}],"quality_controlled":"1","author":[{"last_name":"Asadi","id":"02d96aae-000e-11ec-b801-cadd0a5eefbb","first_name":"Ali","full_name":"Asadi, Ali"},{"last_name":"Chatterjee","orcid":"0000-0002-4561-241X","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","full_name":"Chatterjee, Krishnendu"},{"full_name":"Kafshdar Goharshadi, Ehsan","last_name":"Kafshdar Goharshadi","orcid":"0000-0002-8595-0587","id":"103b4fa0-896a-11ed-bdf8-87b697bef40d","first_name":"Ehsan"},{"last_name":"Karrabi","id":"67638922-f394-11eb-9cf6-f20423e08757","first_name":"Mehrdad","orcid":"0009-0007-5253-9170","full_name":"Karrabi, Mehrdad"},{"full_name":"Shafiee, Ali","id":"2783031a-7378-11f0-b2d0-f17f1db2ebad","first_name":"Ali","last_name":"Shafiee"}],"department":[{"_id":"KrCh"},{"_id":"GradSch"}],"title":"Qualitative analysis of ω-regular objectives on robust MDPs","publication_identifier":{"eissn":["2374-3468"],"issn":["2159-5399"]},"arxiv":1,"type":"conference","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2505.04539"}]},{"has_accepted_license":"1","citation":{"short":"N.T.

Specifically, our framework dynamically maintains a variant of the hierarchical 𝑗-tree decomposition of [Madry FOCS’10], achieving a poly-logarithmic approximation factor to the graph’s cut structure and supporting edge updates in 𝑂⁡(𝑛𝜀) amortized update time, for any arbitrarily small constant 𝜀 ∈(0,1).\r\nConsequently, we obtain new trade-offs between approximation and update/query time for fundamental cut-based optimization problems in the fully dynamic setting, including all-pairs minimum cuts, sparsest cut, multi-way cut, and multi-cut. For the last three problems, these trade-offs give the first fully-dynamic algorithms achieving poly-logarithmic approximation in sub-linear time per operation.\r\nThe main technical ingredient behind our dynamic hierarchy is a dynamic cut-sparsifier algorithm that can handle vertex splits with low recourse. This is achieved by white-boxing the dynamic cut sparsifier construction of [Abraham et al. FOCS’16], based on forest packing, together with new structural insights about the maintenance of these forests under vertex splits. Given the versatility of cut sparsification in both the static and dynamic graph algorithms literature, we believe this construction may be of independent interest."}],"author":[{"first_name":"Gramoz","last_name":"Goranci","full_name":"Goranci, Gramoz"},{"full_name":"Henzinger, Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630","first_name":"Monika H","orcid":"0000-0002-5008-6530","last_name":"Henzinger"},{"first_name":"Peter","last_name":"Kiss","full_name":"Kiss, Peter"},{"first_name":"Ali","last_name":"Momeni","full_name":"Momeni, Ali"},{"last_name":"Zöcklein","first_name":"Gernot","id":"45d5e826-47af-11f1-84e5-ba87c23fe681","full_name":"Zöcklein, Gernot"}],"department":[{"_id":"MoHe"}],"title":"Dynamic hierarchical j-tree decomposition and its applications","arxiv":1,"publication_identifier":{"isbn":["9781611978971"],"eissn":["15579468"],"issn":["10719040"]},"type":"conference","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2601.09139","open_access":"1"}],"ec_funded":1,"month":"01","publication":"Proceedings of the 2026 Annual ACM SIAM Symposium on Discrete Algorithms","external_id":{"arxiv":["2601.09139"]},"year":"2026","citation":{"chicago":"Goranci, Gramoz, Monika Henzinger, Peter Kiss, Ali Momeni, and Gernot Zöcklein. “Dynamic Hierarchical J-Tree Decomposition and Its Applications.” In <i>Proceedings of the 2026 Annual ACM SIAM Symposium on Discrete Algorithms</i>, 2026–January:1128–80.

They are force-free and can be described as hydrodynamic force dipoles: pushers or pullers. This modelling description is broadly used in biological physics and active matter research, and it has successfully predicted, for example, the superfluid behaviour of suspensions of pushers or the bend instability and emergence of turbulent flows in active nematics. However, this description accounts only for the translational motion of the swimming body and neglects the effects of hydrodynamic torque dipoles, which are relevant to bacteria with rotary motor-driven flagella, such as swimming Escherichia coli. Here we show that the torque dipole of confined swimming E. coli can power the persistent rotation of symmetric discs. The torque dipole leads to a traction force on the discs, an additive mechanism that is both contactless and independent of the orientation of the bacteria. Our results indicate that the torque dipole of swimming E. coli is notable in confined geometries, which is relevant to bacterial transport through porous materials, biofilms and the development of chiral fluids."}]}]
