However, the origin and evolution of WD magnetism remain under debate. Two WD pulsars, AR Sco and J191213.72–441045.1 (J1912), have been found, which are non-accreting binaries hosting rapidly spinning (1.97 minutes and 5.30 minutes, respectively) magnetic WDs. The WD in AR Sco is slowing down on a (math formular) yr timescale. It is believed they will eventually become polars, accreting systems in which a magnetic WD (B  ≈ 10−240 MG) accretes from a Roche lobe-filling donor spinning in sync with the orbit (≳78 minutes). Here, we present multiwavelength data and analysis of Gaia22ayj, which outbursted in 2022 March. We find that Gaia22ayj is a magnetic accreting WD that is rapidly spinning down (math formular\r\n yr) like WD pulsars, but shows clear evidence of accretion, like polars. Strong linear polarization (40%) is detected in Gaia22ayj; such high levels have only been seen in the WD pulsar AR Sco and demonstrate the WD is magnetic. High speed photometry reveals a 9.36 minutes period accompanying a high amplitude (∼2 mag) modulation. We associate this with a WD spin or spin–orbit beat period, not an orbital period as was previously suggested. Fast (60 s) optical spectroscopy reveals a broad \"hump,\" reminiscent of cyclotron emission in polars, between 4000 and 8000 Å. We find an X-ray luminosity of (math formular) in the 0.3–8 keV energy range, while two very large array radio campaigns resulted in a non-detection with a Fr < 15.8 μJy 3σ upper limit. The shared properties of both WD pulsars and polars suggest that Gaia22ayj is a missing link between the two classes of magnetic WD binaries.","lang":"eng"}],"oa_version":"Published

They sustain chemical gradients and fluid flows that propel them by phoresis. This leads to unconventional behavior and collective dynamics, such as self-organization into complex structures. Characterizing the nonequilibrium interactions of microswimmers is crucial for advancing our understanding of active systems. However, this remains a challenge owing to the importance of fluctuations at the microscale and the difficulty in disentangling the different contributions to the interactions. Here, we show a massive dependence of the nonequilibrium interactions on the shape of catalytic microswimmers. We perform tracking experiments at high throughput to map interactions between nanocolloidal tracers and dimeric microswimmers of various aspect ratios. Our method leverages dual tracers with differing phoretic mobilities to quantitatively disentangle phoretic motion from hydrodynamic advection. This approach is validated through experiments on single chemically active sites and on immobilized catalytic microswimmers. We further investigate the activity-driven interactions of free microswimmers and directly measure their phoretic interactions. When compared to standard models, our findings highlight the important role of osmotic flows for microswimmers near surfaces and reveal an enhanced contribution of hydrodynamic advection relative to phoretic motion as the size of the microswimmer increases. Our study provides robust measurements of the nonequilibrium interactions from catalytic microswimmers and lays the groundwork for a realistic description of active systems.","lang":"eng"}],"date_published":"2025-03-11T00:00:00Z","pmid":1,"isi":1,"main_file_link":[{"open_access":"1","url":"https://hal.science/hal-04682818v2"}],"date_updated":"2025-10-16T10:26:59Z","acknowledgement":"The authors thank M.

Climate change is expected to induce shifts in the composition, structure and functioning of Arctic tundra ecosystems. Increases in the frequency and severity of tundra fires have the potential to catalyse vegetation transitions with far-reaching local, regional and global consequences.\r\n2. We propose that post-fire tundra recovery, coupled with climate change, may not necessarily lead to pre-fire conditions. Our hypothesis, based on surveys and literature, suggests two climate–fire driven trajectories. One trajectory results in increased woody vegetation under low fire frequency; the other results in grass dominance under high frequency.\r\n3. Future research should address uncertainties regarding possible tundra ecosystem shifts linked to fires, using methods that encompass greater temporal and spatial scales than previously addressed. More case studies, especially in underrepresented regions and ecosystem types, are essential to broaden the empirical basis for forecasts and potential fire management strategies.\r\n4. Synthesis. Our review synthesises current knowledge on post-fire vegetation trajectories in Arctic tundra ecosystems, highlighting potential transitions and alternative ecosystem states and their implications. We discuss challenges in defining and predicting these trajectories as well as future directions."}],"day":"01","isi":1,"date_published":"2025-05-01T00:00:00Z","file":[{"date_updated":"2025-12-30T08:08:18Z","success":1,"file_name":"2025_JournEcology_Heim.pdf","creator":"dernst","checksum":"e2785ae265e211b4dc7fc9c5b7744948","relation":"main_file","access_level":"open_access","file_id":"20890","content_type":"application/pdf","date_created":"2025-12-30T08:08:18Z","file_size":2662766}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":113,"file_date_updated":"2025-12-30T08:08:18Z","year":"2025","PlanS_conform":"1","publication_status":"published","oa":1,"OA_type":"hybrid","has_accepted_license":"1","intvolume":"       113","issue":"5","publication":"Journal of Ecology","author":[{"first_name":"Ramona Julia","last_name":"Heim","full_name":"Heim, Ramona Julia"},{"full_name":"Rocha, Adrian V.","last_name":"Rocha","first_name":"Adrian V."},{"full_name":"Zemlianskii, Vitalii","last_name":"Zemlianskii","first_name":"Vitalii"},{"first_name":"Kirsten","full_name":"Barrett, Kirsten","last_name":"Barrett"},{"first_name":"Helga","full_name":"Bültmann, Helga","last_name":"Bültmann"},{"full_name":"Breen, Amy","last_name":"Breen","first_name":"Amy"},{"last_name":"Frost","full_name":"Frost, Gerald Verner","first_name":"Gerald Verner"},{"full_name":"Hollingsworth, Teresa Nettleton","last_name":"Hollingsworth","first_name":"Teresa Nettleton"},{"last_name":"Jandt","full_name":"Jandt, Randi","first_name":"Randi"},{"first_name":"Maria","full_name":"Kozlova, Maria","last_name":"Kozlova"},{"full_name":"Kurka, Anastasiya","last_name":"Kurka","first_name":"Anastasiya"},{"last_name":"Jorgenson","full_name":"Jorgenson, Mark Torre","first_name":"Mark Torre"},{"first_name":"Simon M.","last_name":"Landhäusser","full_name":"Landhäusser, Simon M."},{"first_name":"Michael Mark","full_name":"Loranty, Michael Mark","last_name":"Loranty"},{"first_name":"Eric A.","full_name":"Miller, Eric A.","last_name":"Miller"},{"full_name":"Narita, Kenji","last_name":"Narita","first_name":"Kenji"},{"first_name":"Evgeniya","id":"0b30719b-13f0-11ed-ab2a-94498bc6a278","full_name":"Pravdolyubova, Evgeniya","last_name":"Pravdolyubova"},{"full_name":"Hölzel, Norbert","last_name":"Hölzel","first_name":"Norbert"},{"first_name":"Gabriela","last_name":"Schaepman-Strub","full_name":"Schaepman-Strub, Gabriela"}],"department":[{"_id":"NiBa"}],"publisher":"Wiley","language":[{"iso":"eng"}],"_id":"19442","article_processing_charge":"Yes (via OA deal)","scopus_import":"1","date_created":"2025-03-23T23:01:27Z"},{"page":"820-827.e4","external_id":{"pmid":["39947174"],"isi":["001463196100001"]},"title":"FakET: Simulating cryo-electron tomograms with neural style transfer","OA_place":"publisher","quality_controlled":"1","status":"public","acknowledgement":"The IMP and D.H. are generously funded by Boehringer Ingelheim.

Recent deep learning solutions, though successful, require extensive training datasets. The protracted generation time of physics-based models, often employed to produce these datasets, limits their broad applicability. We introduce FakET, a method based on neural style transfer, capable of simulating the forward operator of any cryo transmission electron microscope. It can be used to adapt a synthetic training dataset according to reference data producing high-quality simulated micrographs or tilt-series. To assess the quality of our generated data, we used it to train a state-of-the-art localization and classification architecture and compared its performance with a counterpart trained on benchmark data. Remarkably, our technique matches the performance, boosts data generation speed 750x, uses 33x less memory, and scales well to typical transmission electron microscope detector sizes. It leverages GPU acceleration and parallel processing.

Our task is to reconfigure one into the other using small steps while ensuring the intermediate configurations of tokens are also valid solutions. The two commonly studied settings are Token Jumping and Token Sliding, which allows moving a single token to an arbitrary or an adjacent vertex, respectively.\r\n\r\nWe introduce new rules that generalize Token Jumping, parameterized by the number of tokens allowed to move at once and by the maximum distance of each move. Our main contribution is identifying minimal rules that allow reconfiguring any possible given solution into any other for Independent Set, Vertex Cover, and Dominating Set. For each minimal rule, we also provide an efficient algorithm that finds a corresponding reconfiguration sequence.\r\n\r\nWe further focus on the rule that allows each token to move to an adjacent vertex in a single step. This natural variant turns out to be the minimal rule that guarantees reconfigurability for Vertex Cover. We determine the computational complexity of deciding whether a (shortest) reconfiguration sequence exists under this rule for the three studied problems. While reachability for Vertex Cover is shown to be in P, finding a shortest sequence is shown to be NP-complete. For Independent Set and Dominating Set, even reachability is shown to be PSPACE-complete.","lang":"eng"}],"date_published":"2025-02-20T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2411.12582"}],"isi":1,"date_updated":"2025-09-30T11:14:33Z","acknowledgement":"J.

In neuroscience, this fact has inspired several recent studies in sensory and motor systems. However, less is known about how higher associational cortical areas, such as the hippocampus, modify representations throughout the learning of complex tasks. Here, we focus on associative learning, a process that requires forming a connection between the representations of different variables for appropriate behavioral response. We trained rats in a space-context associative task and monitored hippocampal neural activity throughout the entire learning period, over several days. This allowed us to assess changes in the representations of context, movement direction, and position, as well as their relationship to behavior. We identified a hierarchical representational structure in the encoding of these three task variables that was preserved throughout learning. Nevertheless, we also observed changes at the lower levels of the hierarchy where context was encoded. These changes were local in neural activity space and restricted to physical positions where context identification was necessary for correct decision-making, supporting better context decoding and contextual code compression. Our results demonstrate that the hippocampal code not only accommodates hierarchical relationships between different variables but also enables efficient learning through minimal changes in neural activity space. Beyond the hippocampus, our work reveals a representation learning mechanism that might be implemented in other biological and artificial networks performing similar tasks."}],"type":"journal_article","doi":"10.1073/pnas.2417025122","month":"03","publication_identifier":{"eissn":["1091-6490"],"issn":["0027-8424"]},"citation":{"ieee":"H.

The amplitude of the background is somewhat higher than expected in most previous population models or from the local mass density observations. Such binaries are expected to be produced in galaxy mergers, which are also thought to trigger bright quasar activity. Under the assumptions that (i) a fraction fbin∼1 of all quasars are associated with mergers, (ii) the typical quasar lifetime is tQ∼108 yr, and (iii) adopting Eddington ratios fEdd∼0.25 for the luminosity of quasars, we compute the GW background associated directly with the empirically measured quasar luminosity function. This approach bypasses the need to model the cosmological evolution of black holes or galaxy mergers from simulations or semi-analytical models. We find the amplitude matching the value measured by NANOGrav. Our results are consistent with most quasars being associated with black hole binaries and being the sources of the GW background, and imply a joint constraint on tQ, fEdd and the typical mass ratio q≡M2/M1. The signal in this case would be dominated by relatively distant ∼109M⊙ sources at z≈2−3, at the peak of quasar activity. Similarly to other models, our results remain in tension with the local super-massive black hole mass density.","lang":"eng"}],"date_published":"2025-04-04T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2412.12726"}],"isi":1,"publication_identifier":{"issn":["0264-9381"],"eissn":["1361-6382"]},"citation":{"apa":"Kis-Tóth, Á., Haiman, Z., &#38; Frei, Z.

Using stochastic techniques from computer science, our method presents a computational tool to compute exact accuracy guarantees and synthesize optimal algorithms that are often different from traditional ones.

The time-dependent degree of alignment is recorded using femtosecond-probe-pulse-induced Coulomb explosion into a pair of Ak+ fragment ions. The results, obtained for Na2, K2, and Rb2 in both the ground state 11Σ+g and the lowest-lying triplet state 13Σ+u, exhibit distinct, periodic revivals with a gradually decreasing amplitude. The dynamics differ from that expected for dimers had they behaved as free rotors. Numerically, we solve the time-dependent rotational Schrödinger equation, including an effective mean-field potential to describe the interaction between the dimer and the droplet. The experimental and simulated alignment dynamics agree well and their comparison enables us to determine the effective rotational constants of the alkali dimers with the exception of Rb2(13Σ+u) that only exhibits a prompt alignment peak but no subsequent revivals. For Na2(13Σ+u), K2(11Σ+g), K2(13Σ+u) and Rb2(11Σ+g), the alignment dynamics are well-described by a 2D rotor model. We ascribe this to a significant confinement of the internuclear axis of these dimers, induced by the orientation-dependent droplet-dimer interaction, to the tangential plane of their residence point on the droplet."}],"article_type":"original","date_updated":"2025-09-30T11:27:25Z","acknowledgement":"H.S. acknowledges support from the Villum Foundation through a Villum Investigator Grant No. 25886.

The early disks detected so far, with typical half-light radii of 3 kpc at stellar masses around 1011 M⊙ for redshift z ≈ 3, are significantly smaller than today’s disks with similar masses, which is in agreement with expectations from current galaxy models. Here we report observations of a giant disk at z = 3.25, when the Universe was only two billion years old, with a half-light radius of 9.6 kpc and stellar mass of (math formular). This galaxy is larger than any other kinematically confirmed disks at similar epochs and is surprisingly similar to today’s largest disks with regard to size and mass. James Webb Space Telescope imaging and spectroscopy reveal its spiral morphology and a rotational velocity consistent with a local Tully–Fisher relationship. Multiwavelength observations show that it lies in an exceptionally dense environment, where the galaxy number density is more than ten times higher than the cosmic average and mergers are frequent. The discovery of such a giant disk suggests the presence of favourable physical conditions for large-disk formation in dense environments in the early Universe, which may include efficient accretion of gas carrying coherent angular momentum and non-destructive mergers between exceptionally gas-rich progenitor galaxies.","lang":"eng"}],"oa_version":"Published Version","arxiv":1,"day":"17","publication_status":"published","has_accepted_license":"1","OA_type":"hybrid","oa":1,"volume":9,"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2025","file_date_updated":"2025-08-05T12:49:36Z","publication":"Nature Astronomy","intvolume":"         9","department":[{"_id":"JoMa"}],"author":[{"first_name":"Weichen","last_name":"Wang","full_name":"Wang, Weichen"},{"last_name":"Cantalupo","full_name":"Cantalupo, Sebastiano","first_name":"Sebastiano"},{"last_name":"Pensabene","full_name":"Pensabene, Antonio","first_name":"Antonio"},{"full_name":"Galbiati, Marta","last_name":"Galbiati","first_name":"Marta"},{"full_name":"Travascio, Andrea","last_name":"Travascio","first_name":"Andrea"},{"full_name":"Steidel, Charles C.","last_name":"Steidel","first_name":"Charles C."},{"full_name":"Maseda, Michael V.","last_name":"Maseda","first_name":"Michael V."},{"first_name":"Gabriele","full_name":"Pezzulli, Gabriele","last_name":"Pezzulli"},{"first_name":"Stephanie","last_name":"De Beer","full_name":"De Beer, Stephanie"},{"last_name":"Fossati","full_name":"Fossati, Matteo","first_name":"Matteo"},{"first_name":"Michele","last_name":"Fumagalli","full_name":"Fumagalli, Michele"},{"first_name":"Sofia G.","full_name":"Gallego, Sofia G.","last_name":"Gallego"},{"last_name":"Lazeyras","full_name":"Lazeyras, Titouan","first_name":"Titouan"},{"first_name":"Ruari","full_name":"Mackenzie, Ruari","last_name":"Mackenzie"},{"full_name":"Matthee, Jorryt J","last_name":"Matthee","id":"7439a258-f3c0-11ec-9501-9df22fe06720","first_name":"Jorryt J","orcid":"0000-0003-2871-127X"},{"first_name":"Themiya","full_name":"Nanayakkara, Themiya","last_name":"Nanayakkara"},{"last_name":"Quadri","full_name":"Quadri, Giada","first_name":"Giada"}],"scopus_import":"1","article_processing_charge":"No","date_created":"2025-04-06T22:01:32Z","publisher":"Springer Nature","_id":"19504","language":[{"iso":"eng"}]},{"intvolume":"        35","issue":"1","publication":"Annals of Applied Probability","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","volume":35,"year":"2025","publication_status":"published","ec_funded":1,"oa":1,"OA_type":"green","publisher":"Institute of Mathematical Statistics","_id":"19505","language":[{"iso":"eng"}],"article_processing_charge":"No","scopus_import":"1","date_created":"2025-04-06T22:01:32Z","author":[{"full_name":"Agresti, Antonio","last_name":"Agresti","orcid":"0000-0002-9573-2962","first_name":"Antonio","id":"673cd0cc-9b9a-11eb-b144-88f30e1fbb72"},{"first_name":"Matthias","full_name":"Hieber, Matthias","last_name":"Hieber"},{"first_name":"Amru","last_name":"Hussein","full_name":"Hussein, Amru"},{"first_name":"Martin","last_name":"Saal","full_name":"Saal, Martin"}],"department":[{"_id":"JuFi"}],"project":[{"call_identifier":"H2020","grant_number":"948819","_id":"0aa76401-070f-11eb-9043-b5bb049fa26d","name":"Bridging Scales in Random Materials"}],"page":"635-700","external_id":{"arxiv":["2210.05973"],"isi":["001434322900016"]},"title":"The stochastic primitive equations with nonisothermal turbulent pressure","OA_place":"repository","quality_controlled":"1","status":"public","acknowledgement":"The first author thanks Umberto Pappalettera for helpful suggestions on Section 2 and for bringing to his attention the reference [56].

They are derived from the Navier–Stokes equations by employing stochastic versions of the Boussinesq and the hydrostatic approximations. The temperature dependence of the turbulent pressure can be seen as a consequence of an additive noise acting on the small vertical dynamics. For such a model we prove global well-posedness in H^1 where the noise is considered in both the Itô and Stratonovich formulations. Compared to previous variants of the primitive equations, the one considered here presents a more intricate coupling between the velocity field and the temperature. The corresponding analysis is seriously more involved than in the deterministic setting. Finally, the continuous dependence on the initial data and the energy estimates proven here are new, even in the case of isothermal turbulent pressure.","lang":"eng"}],"arxiv":1,"day":"01","isi":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2210.05973"}],"date_published":"2025-02-01T00:00:00Z","month":"02","citation":{"ieee":"A.

Nevertheless, it is unclear whether reactivated assemblies are static or whether they reorganize gradually over prolonged sleep. We tracked reactivated CA1 assembly patterns over ∼20 h of sleep/rest periods and related them to assemblies seen before or after in a spatial learning paradigm using rats. We found that reactivated assembly patterns were gradually transformed and started to resemble those seen in the subsequent recall session. Periods of rapid eye movement (REM) sleep and non-REM (NREM) had antagonistic roles: whereas NREM accelerated the assembly drift, REM countered it. Moreover, only a subset of rate-changing pyramidal cells contributed to the drift, whereas stable-firing-rate cells maintained unaltered reactivation patterns. Our data suggest that prolonged sleep promotes the spontaneous reorganization of spatial assemblies, which can contribute to daily cognitive map changes or encoding new learning situations.","lang":"eng"}],"oa_version":"Published Version","day":"07","isi":1,"pmid":1,"date_published":"2025-05-07T00:00:00Z","file":[{"file_name":"2025_Neuron_Bollmann.pdf","success":1,"date_updated":"2025-08-05T12:43:44Z","access_level":"open_access","relation":"main_file","checksum":"5e57852a45a78a751dd3a5e807bf015f","creator":"dernst","content_type":"application/pdf","file_id":"20133","file_size":27047730,"date_created":"2025-08-05T12:43:44Z"}],"month":"05","publication_identifier":{"issn":["0896-6273"],"eissn":["1097-4199"]},"citation":{"ista":"Bollmann L, Baracskay P, Stella F, Csicsvari JL. 2025.

However, our knowledge of how this barrier forms during development and is subsequently maintained remains incomplete. The infundibulum is a cylindrical epidermal tissue compartment that serves as an outlet for hair follicles protruding from the skin and the excretion of the sebaceous glands that are essential for proper skin function. In this study, we applied quantitative fate mapping to address how infundibulum are maintained during adulthood. We demonstrate that progenitors build and maintain tissues through stochastic cell fate choices. Long-term analysis identified a preferential transient contribution from cells initially located at the bottom of the structure to the maintenance of the tissue, with bursts of local progenitor expansion associated with the phases of hair growth. Beyond providing compartment-wide insights into progenitor cell dynamics in infundibulum, these findings demonstrate how spatiotemporal regulation controls transient progenitor dominance.","lang":"eng"}],"day":"01","ddc":["570"],"tmp":{"image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)"},"article_type":"original","acknowledgement":"We thank the members of the Jensen Laboratory for experimental and technical advice, the imaging facilities at reNEW, and animal caretakers for expert assistance.
