To fulfil these functions, GABAB receptors form macromolecular signaling complexes with G proteins, effectors, and other associated proteins. Here we investigated the postnatal development of GABAB receptors (GABAB1 and GABAB2 subunits) in mouse brain, focusing on potential similarities in the spatial and temporal expression pattern\r\nof their associated proteins CaV2.1, Gαo, Gβ5, and RGS7, using histoblots, immunofluorescence, and immunoelectron microscopic techniques. At all ages analyzed, histoblot showed that the six proteins were widely expressed in the brain, with mostly an\r\noverlapping pattern throughout postnatal development. In the hippocampus, immunoelectron microscopy and quantitative analysis of immunoparticles for GABAB1, GABAB2, Gαo, Gβ5, and RGS7 revealed their progressive enrichment around excitatory synapses on dendritic spines of CA1 pyramidal cells toward P15. At presynaptic sites, GABAB receptors colocalize with\r\nCaV2.1, Gαo, Gβ5, and RGS7 in the active zone and extrasynaptic membranes of axon terminals, establishing synapses on dendritic spines of CA1 pyramidal cells. In the cerebellum, double immunofluorescence at P7 and P10 revealed the colocalization of GABAB1 and CaV2.1\r\nin the whole dendritic tree of developing Purkinje cells. Immunoelectron microscopy at P15 showed that GABAB1, GABAB2, CaV2.1, Gαo, Gβ5, and RGS7 are distributed along the dendritic surface of Purkinje cells, enriched close to excitatory synapses in spines.\r\nAltogether, these data suggest that macromolecular complexes composed of GABAB1 /GABAB2/CaV2.1/ Gαo/Gβ5/RGS7 are pre-assembled during key stages of postnatal development in hippocampal and cerebellar neurons.","lang":"eng"}],"intvolume":"        40","OA_place":"publisher","publication":"Histology and Histopathology","OA_type":"gold","publication_identifier":{"eissn":["1699-5848"]},"month":"12","scopus_import":"1","volume":40,"article_processing_charge":"Yes","citation":{"short":"C.

Galaxy sizes were measured in JWST near-infrared camera observations in rest-frame Hα (tracing recent star formation) with the F466N and F470N narrow-band filters from JELS, and\r\ncompared against rest-R- and V -band (tracing established stellar populations) and near-ultraviolet sizes. We find a size–stellar mass(re − M∗) relationship with a slope that is consistent with literature values at lower redshifts, though offset to lowersizes. We observe a large scatter in re at low stellar mass (M∗ < 10^8.4 Mo) which we believe is the result of bursty star formation histories (SFHs) of SF galaxies at the Epoch of Reionization (EoR). We find that the stellar and ionized gas components are similar in size at z = 6.1. The evidence of already-established stellar components in these Hα emitters (HAEs) indicates previous episodes of star formation have occurred. As such, following other JELS studies finding our HAEs are undergoing a current burst of star formation, we believe our results indicate that SF galaxies at the end of the EoR have already experienced a bursty SFH. From our re − M∗ relationship, we find re,F444W = 0.76 ± 0.46 kpc for fixed stellar mass M∗ = 10^9.25 M, which is in agreement with other observations and simulations of SF galaxies in the literature. We find a close-pair (major) merger fraction of (fmaj. merger =0.44 ± 0.22) fmerger = 0.43 ± 0.11 for galaxy separations d <~ 25 kpc, which is in agreement with other z ≈ 6 studies."}],"has_accepted_license":"1","title":"The JWST Emission Line Survey (JELS): The sizes and merger fraction of star-forming galaxies during the Epoch of Reionization","publication_status":"published","day":"01","quality_controlled":"1","oa":1,"acknowledgement":"This work makes use of ASTROPY, 7 a community-developed core PYTHON package for Astronomy (Astropy Collaboration 2013, 2018, 2022), as well as the NUMPY (C.

From approximately 120 candidates, we identify 12 objects with at least two prominent emission lines among [O II] λ3727, H β λ4861, [O III] λ4959, [O III] λ5007, and H α λ6563 that are spectroscopically confirmed by both instruments. Our key findings reveal systematic differences between the two spectrographs based on source morphology and shutter aperture placement. Compact objects show comparable or higher\r\nintegrated flux in NIRSpec relative to NIRISS (within 1σ uncertainties), while extended sources consistently display higher flux in NIRISS measurements. This pattern reflects NIRSpec’s optimal coverage for compact objects while potentially undersampling extended sources. Quantitative analysis demonstrates that NIRSpec recovers at least 63 per cent of NIRISS-measured flux when the slit covers >15 per cent of the source or when Re < 1 kpc. For lower coverage or larger effective radii, the recovered flux varies from 24 per cent to 63 per cent. When studying the H α λ6563/[O III] λ5007 emission line ratio, we observe that\r\nmeasurements from these different spectrographs can vary by up to ∼0.3 dex, with significant implications for metallicity and star formation rate characterizations for individual galaxies.

Since the current model of root gravitropism has not been able to integrate all aspects of the response (perception, response, and behavior), research on gravitropism has been dominated by different theories attempting to conceptualize each aspect individually. In this work, we sought to reevaluate all the main components of the root graviresponse through the lens of angle dependence. We show angle dependence in Cholodny–Went-based auxin asymmetry and growth response, which we tracked back to angle-dependent variation in PIN asymmetry and statolith sedimentation in the columella. Thanks to this approach, we were able to suggest distinct roles for PINs and columella cell tiers, and a potential function for auxin vertical flux through the columella. Our findings provide a unifying framework to further explore the mechanisms that regulate angle-dependent gravitropic response, with major implications of time-dependent features of root graviresponse.","lang":"eng"}],"intvolume":"       122","has_accepted_license":"1","publication_status":"published","title":"Angle dependence as a unifying feature of root graviresponse modules","volume":122,"scopus_import":"1","month":"11","publication_identifier":{"eissn":["1091-6490"]},"oa":1,"acknowledgement":"This study was funded by the BBSRC (grant no.

Here, we provide a quantitative estimate of the carbon emissions associated with conference attendance by analyzing travel data from participants of 10 international conferences in the field of magnetic resonance, namely EUROMAR, ENC and ICMRBS. We find that attending a EUROMAR conference produces, on average, more than 1 t CO2 eq.. For the analyzed conferences outside Europe, the corresponding value is about 2–3 times higher, on average, with intercontinental trips amounting to up to 5 t. We compare these conference-related emissions to other activities associated with research and show that conference travel is a substantial portion of the total climate footprint of a researcher in magnetic resonance. We explore several strategies to reduce these emissions, including the impact of selecting conference venues more strategically and the possibility of decentralized conferences. Through a detailed comparison of train versus air travel – accounting for both direct and infrastructure-related emissions – we demonstrate that train travel offers considerable carbon savings. These data may provide a basis for strategic choices of future conferences in the field and for individuals deciding on their conference attendance.","lang":"eng"}],"publication":"Magnetic Resonance","OA_place":"publisher","publication_status":"published","title":"Quantifying the carbon footprint of conference travel: The case of NMR meetings","corr_author":"1","has_accepted_license":"1"},{"author":[{"first_name":"Georgios","id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis","full_name":"Koutentakis, Georgios"},{"first_name":"S.

In particular, we consider coherently coupled spin states with an external field, where only one spin component interacts with the bath, enabling light dressing of the impurity and spin-dependent bath-impurity interactions. Through detailed comparisons with ab-initio many-body simulations, we demonstrate that the composite system is accurately described by a simplified effective Hamiltonian. The latter builds upon previously developed effective potential approaches in the absence of light dressing. It can be used to extract the impurity energy, residue, effective mass, and anharmonicity induced by the phononic dressing. Light-dressing is shown to increase the polaron residue, undressing the impurity from phononic excitations because of strong spin coupling. For strong repulsions, previously shown to trigger dynamical Bose polaron decay (a phenomenon called temporal orthogonality catastrophe), it is explained that strong light-dressing stabilizes a repulsive polaron-dressed state. Our results establish the effective Hamiltonian framework as a powerful tool for exploring strongly interacting polaronic systems and corroborating forthcoming experimental realizations.","lang":"eng"}],"has_accepted_license":"1","title":"Competition of light-and phonon-dressing in microwave-dressed Bose polarons","publication_status":"published","corr_author":"1","OA_type":"diamond","day":"01","quality_controlled":"1","status":"public","date_published":"2025-10-01T00:00:00Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2025-11-23T23:01:39Z","type":"journal_article","article_type":"original","publisher":"SciPost Foundation","ddc":["530"],"issue":"4","year":"2025","file_date_updated":"2025-11-24T08:42:42Z","DOAJ_listed":"1","oa_version":"Published Version","article_number":"093","_id":"20666","file":[{"date_updated":"2025-11-24T08:42:42Z","access_level":"open_access","checksum":"04d0e47ba66c63737431d7b8ed1df4bc","file_id":"20673","file_name":"2025_SciPostPhys_Koutentakis.pdf","file_size":1725787,"creator":"dernst","relation":"main_file","content_type":"application/pdf","success":1,"date_created":"2025-11-24T08:42:42Z"}],"PlanS_conform":"1","doi":"10.21468/SciPostPhys.19.4.093","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"external_id":{"arxiv":["2504.03411"],"isi":["001593017800002"]},"date_updated":"2025-12-01T15:22:01Z","department":[{"_id":"MiLe"}]},{"quality_controlled":"1","date_updated":"2025-11-24T08:53:34Z","day":"20","department":[{"_id":"MaMo"}],"title":"Mean estimation in high-dimensional binary timeinhomogeneous Markov Gaussian mixture models","_id":"20667","publication_status":"published","abstract":[{"text":"We explore the problem of mean estimation for a high-dimensional binary symmetric Gaussian mixture model, where the label (sign) follows a time-inhomogeneous Markov chain.

In this paper, we conduct the most comprehensive empirical study to date, evaluating FP8, INT8, and INT4\r\nquantization across academic benchmarks and real-world tasks on the entire Llama-3.1 model\r\nfamily. Through over 500,000 evaluations, our investigation yields several key findings: (1) FP8 (W8A8-FP) is effectively lossless across all model scales, (2) well-tuned INT8 (W8A8-INT) achieves surprisingly low (1-3%) accuracy degradation, and (3) INT4 weightonly (W4A16-INT) is more competitive than expected, rivaling 8-bit quantization. Further, we investigate the optimal quantization format for different deployments by analyzing inference performance through the popular vLLM framework. Our analysis provides clear deployment recommendations: W4A16 is the most cost-efficient for synchronous setups, while W8A8 dominates in asynchronous\r\ncontinuous batching. For mixed workloads, the optimal choice depends on the specific use\r\ncase. Our findings offer practical, data-driven guidelines for deploying quantized LLMs at scale—ensuring the best balance between speed, efficiency, and accuracy.

In only 3 years, nextGEMS achieved this milestone with the two km-scale Earth system models, ICOsahedral Non-hydrostatic model (ICON) and Integrated Forecasting System coupled to the Finite-volumE Sea ice-Ocean Model (IFS-FESOM). nextGEMS was based on three cornerstones: (1) developing km-scale Earth system models with small errors in the energy and water balance, (2) performing km-scale climate simulations with a throughput greater than 1 simulated year per day, and (3) facilitating new workflows for an efficient analysis of the large simulations with common data structures and output variables. These cornerstones shaped the timeline of nextGEMS, divided into four cycles. Each cycle marked the release of a new configuration of ICON and IFS-FESOM, which were evaluated at hackathons. The hackathon participants included experts from climate science, software engineering, and high-performance computing as well as users from the energy and agricultural sectors. The continuous efforts over the four cycles allowed us to produce 30-year simulations with ICON and IFS-FESOM, spanning the period 2020–2049 under the SSP3-7.0 scenario. The throughput was about 500 simulated days per day on the Levante supercomputer of the German Climate Computing Center (DKRZ). The simulations employed a horizontal grid of about 5 km resolution in the ocean and 10 km resolution in the atmosphere and land. Aside from this technical achievement, the simulations allowed us to gain new insights into the realism of ICON and IFS-FESOM. Beyond its time frame, nextGEMS builds the foundation of the Climate Change Adaptation Digital Twin developed in the Destination Earth initiative and paves the way for future European research on climate change.","lang":"eng"}],"OA_type":"gold","quality_controlled":"1","day":"23","status":"public","date_published":"2025-10-23T00:00:00Z","date_created":"2025-11-24T14:23:07Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","type":"journal_article","publisher":"Copernicus Publications","year":"2025","ddc":["550"],"issue":"20","_id":"20685","file":[{"checksum":"0f6a4af94e3a6be773d0051256bcecf5","access_level":"open_access","date_updated":"2025-11-25T12:02:30Z","creator":"dernst","file_name":"2025_GeosciModelDev_Segura.pdf","file_size":8618996,"file_id":"20692","relation":"main_file","date_created":"2025-11-25T12:02:30Z","content_type":"application/pdf","success":1}],"file_date_updated":"2025-11-25T12:02:30Z","DOAJ_listed":"1","oa_version":"Published Version","doi":"10.5194/gmd-18-7735-2025","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"PlanS_conform":"1","date_updated":"2025-11-25T12:33:05Z","department":[{"_id":"CaMu"}]},{"day":"20","quality_controlled":"1","publication":"Astronomy & Astrophysics","OA_place":"publisher","abstract":[{"text":"Emission from two massive black holes (MBHs) bound in a close binary is expected to be modulated by different processes, such as the Doppler boost due to the orbital motion, accretion rate variability generated by the interaction with a circumbinary disc, and binary gravitational self-lensing. When the binary is compact enough, the two black holes are thought to be surrounded by a common broad-line region that reprocesses the impinging periodically varying ionising flux, creating broad emission lines with variable line shapes. Therefore, the study of broad emission line variability through multi-epoch spectroscopic campaigns is of paramount importance for the unambiguous identification of a binary. In this work, we study the response of a disc-like broad-line region to the Doppler-boosted ionising flux emitted by sub-milliparsec MBH binaries on a circular orbit and compare it with the response of a broad-line region illuminated by a single MBH with a periodically but isotropically varying intrinsic luminosity. We show that in the binary case, the time lags of the blue and red wings of the broad emission lines, arising from diametrically opposite sides of the circumbinary disc, are out of phase by half of the binary’s orbital period, as they each respond to the periodic ‘lighthouse’ modulation from the binary’s continuum emission. This asymmetric time lag represents a new binary signature that cannot be mimicked by a single MBH.","lang":"eng"}],"intvolume":"       702","has_accepted_license":"1","publication_status":"published","title":"Testing compact massive black hole binary candidates through multi-epoch spectroscopy","OA_type":"diamond","publication_identifier":{"issn":["0004-6361"],"eissn":["1432-0746"]},"volume":702,"month":"10","scopus_import":"1","author":[{"last_name":"Bertassi","first_name":"Lorenzo","full_name":"Bertassi, Lorenzo"},{"full_name":"Sottocorno, Erika","first_name":"Erika","last_name":"Sottocorno"},{"last_name":"Rigamonti","first_name":"Fabio","full_name":"Rigamonti, Fabio"},{"full_name":"D’Orazio, Daniel","last_name":"D’Orazio","first_name":"Daniel"},{"first_name":"Michael","last_name":"Eracleous","full_name":"Eracleous, Michael"},{"full_name":"Haiman, Zoltán","orcid":"0000-0003-3633-5403","first_name":"Zoltán","id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman"},{"full_name":"Dotti, Massimo","last_name":"Dotti","first_name":"Massimo"}],"language":[{"iso":"eng"}],"isi":1,"article_processing_charge":"No","citation":{"ieee":"L.

These include degenerate classes such as Markov decision processes or turn-based stochastic games, which can be solved by linear or quadratic programming; however, in practice, value iteration (VI) outperforms the other approaches and is the most implemented method. Similarly, for CSGs, this practical performance makes VI an attractive alternative to the standard theoretical solution via the existential theory of reals.VI starts with an under-approximation of the sought values for each state and iteratively updates them, traditionally terminating once two consecutive approximations are ϵ-close. However, this stopping criterion lacks guarantees on the precision of the approximation, which is the goal of this work.

One of the key differences to additive rewards is that the expected value may diverge to ∞ not only due to recurrent, but also due to transient states.For MCs, computing the value is shown to be possible in polynomial time given an oracle for the comparison of succinctly represented integers (CSRI), which is only known to be solvable in polynomial time subject to number-theoretic conjectures. Interestingly, distinguishing whether the value is ∞ or 0 is at least as hard as CSRI, while determining if it is one of these two can be done in polynomial time. In MDPs, the optimal value can be computed in polynomial space. Further refined complexity results and results on the complexity of optimal schedulers are presented. The techniques developed for MDPs additionally allow to solve the multiplicative variant of the stochastic shortest path problem. Finally, for MCs and MDPs where an absorbing state is reached almost surely, all considered problems are solvable in polynomial time.","lang":"eng"}],"publication":"2025 40th Annual ACM/IEEE Symposium on Logic in Computer Science","OA_place":"repository","publication_status":"published","title":"Multiplicative rewards in Markovian models","corr_author":"1","ec_funded":1,"OA_type":"green","publication_identifier":{"eisbn":["9798331579005"]},"month":"10","scopus_import":"1","project":[{"call_identifier":"H2020","name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818"}],"language":[{"iso":"eng"}],"author":[{"first_name":"Christel","last_name":"Baier","full_name":"Baier, Christel"},{"last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","first_name":"Krishnendu","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu"},{"full_name":"Meggendorfer, Tobias","orcid":"0000-0002-1712-2165","first_name":"Tobias","id":"b21b0c15-30a2-11eb-80dc-f13ca25802e1","last_name":"Meggendorfer"},{"first_name":"Jakob","last_name":"Piribauer","full_name":"Piribauer, Jakob"}],"article_processing_charge":"No","citation":{"ista":"Baier C, Chatterjee K, Meggendorfer T, Piribauer J. 2025.

While CPT was originally considered in one-shot settings for risk-aware decision-making, we consider CPT in sequential decision-making. The most fundamental and well-studied models for sequential decision-making are Markov chains (MCs), and their generalization Markov decision processes (MDPs). The complexity theoretic study of MCs and MDPs with CPT is a fundamental problem that has not been addressed in the literature.Our contributions are as follows: First, we present an alternative viewpoint for the CPT-value of MCs and MDPs. This allows us to establish a connection with multi-objective reachability analysis and conclude the strategy complexity result that memoryless randomized strategies are necessary and sufficient for optimality. Second, based on this connection, we provide an algorithm for computing the CPT-value in MDPs with infinite-horizon objectives. We show that the problem is in EXPTIME and fixed-parameter tractable. Moreover, we provide a polynomial-time algorithm for the special case of MCs."}],"OA_type":"green","ec_funded":1,"type":"conference","publisher":"IEEE","conference":{"location":"Singapore, Singapore","end_date":"2025-06-26","name":"LICS: Logic in Computer Science","start_date":"2025-06-23"},"year":"2025","status":"public","date_published":"2025-10-09T00:00:00Z","date_created":"2025-11-24T14:43:47Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2025-11-25T07:59:49Z","external_id":{"arxiv":["2505.09514"]},"department":[{"_id":"KrCh"}],"_id":"20690","oa_version":"Preprint","doi":"10.1109/lics65433.2025.00041"},{"day":"01","quality_controlled":"1","intvolume":"         6","abstract":[{"text":"Glacier melt sustains water discharge from mountain basins during droughts, but ongoing glacier retreat threatens this fundamental capacity. Here, we assess the response of glaciers in the Southern Andes to one of the most severe, persistent, and extensive droughts on record in South America (2010-present), and to projected end-of-century megadroughts. Using glacio-hydrological numerical simulations, we show that despite a mean annual precipitation deficit of 36%, glacier runoff in 2010-2019 remained almost unaltered compared to the preceding decade (2000-2009), sustained by a 10% loss of total ice volume. However, simulations of future glacier evolution indicate that annual and summer glacier runoff could decline by up to 20 ± 11% and 48 ± 6%, respectively, during end-of-century megadroughts compared to pre-2010 levels. Our results project a weakening of the glacier’s buffering role against precipitation deficits during extreme droughts, increasing water scarcity for ecosystems and livelihoods in the mountain regions of South America.","lang":"eng"}],"publication":"Communications Earth and Environment","OA_place":"publisher","publication_status":"published","title":"Less water from glaciers during future megadroughts in the Southern Andes","has_accepted_license":"1","OA_type":"gold","publication_identifier":{"eissn":["2662-4435"]},"scopus_import":"1","month":"12","volume":6,"language":[{"iso":"eng"}],"project":[{"grant_number":"I06891","_id":"8e4c5b0b-16d5-11f0-9cad-9fa5f341393c","name":"Megadroughts in the Water towers of Europe - from process understanding to strategies for"},{"call_identifier":"FWF","name":"FWF Open Access Fund","_id":"3AC91DDA-15DF-11EA-824D-93A3E7B544D1"}],"author":[{"first_name":"Álvaro","last_name":"Ayala","full_name":"Ayala, Álvaro"},{"first_name":"Eduardo","last_name":"Muñoz-Castro","full_name":"Muñoz-Castro, Eduardo"},{"full_name":"Farinotti, Daniel","first_name":"Daniel","last_name":"Farinotti"},{"first_name":"David","last_name":"Farías-Barahona","full_name":"Farías-Barahona, David"},{"full_name":"Mendoza, Pablo A.","last_name":"Mendoza","first_name":"Pablo A."},{"full_name":"Macdonell, Shelley","last_name":"Macdonell","first_name":"Shelley"},{"full_name":"Mcphee, James","first_name":"James","last_name":"Mcphee"},{"last_name":"Vargas","first_name":"Ximena","full_name":"Vargas, Ximena"},{"id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","first_name":"Francesca","last_name":"Pellicciotti","full_name":"Pellicciotti, Francesca","orcid":"0000-0002-5554-8087"}],"article_processing_charge":"Yes","isi":1,"citation":{"mla":"Ayala, Álvaro, et al. “Less Water from Glaciers during Future Megadroughts in the Southern Andes.” <i>Communications Earth and Environment</i>, vol. 6, 860, Springer Nature, 2025, doi:<a href=\"https://doi.org/10.1038/s43247-025-02845-6\">10.1038/s43247-025-02845-6</a>.","ieee":"Á.

Individual tunneling events are used as the clock’s ticks. We quantify the clock’s precision while measuring the power dissipated by the DQD and, separately, the charge sensor in both direct-current and radio-frequency readout modes. This allows us to probe the thermodynamic cost of creating ticks microscopically and recording them macroscopically. Our experiment is the first to explore the interplay between the entropy produced by a microscopic clockwork and its macroscopic measurement apparatus. We show that the latter contribution not only dwarfs the former but also unlocks greatly increased precision, because the measurement record can be exploited to optimally estimate time even when the DQD is at equilibrium. Our results suggest that the entropy produced by the amplification and measurement of a clock’s ticks, which has often been ignored in the literature, is the most important and fundamental thermodynamic cost of timekeeping at the quantum scale.","lang":"eng"}],"intvolume":"       135","OA_place":"publisher","publication":"Physical Review Letters","title":"Entropic costs of extracting classical ticks from a quantum clock","publication_status":"published","has_accepted_license":"1","OA_type":"hybrid","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"scopus_import":"1","month":"11","volume":135,"language":[{"iso":"eng"}],"author":[{"full_name":"Wadhia, Vivek","last_name":"Wadhia","first_name":"Vivek"},{"full_name":"Meier, Florian","first_name":"Florian","last_name":"Meier"},{"first_name":"Federico","last_name":"Fedele","full_name":"Fedele, Federico"},{"last_name":"Silva","first_name":"Ralph","full_name":"Silva, Ralph"},{"full_name":"Nurgalieva, Nuriya","last_name":"Nurgalieva","first_name":"Nuriya"},{"full_name":"Craig, David L.","last_name":"Craig","first_name":"David L."},{"orcid":"0000-0002-7197-4801","full_name":"Jirovec, Daniel","last_name":"Jirovec","id":"4C473F58-F248-11E8-B48F-1D18A9856A87","first_name":"Daniel"},{"first_name":"Jaime","id":"e0390f72-f6e0-11ea-865d-862393336714","last_name":"Saez Mollejo","full_name":"Saez Mollejo, Jaime"},{"first_name":"Andrea","last_name":"Ballabio","full_name":"Ballabio, Andrea"},{"last_name":"Chrastina","first_name":"Daniel","full_name":"Chrastina, Daniel"},{"last_name":"Isella","first_name":"Giovanni","full_name":"Isella, Giovanni"},{"last_name":"Huber","first_name":"Marcus","full_name":"Huber, Marcus"},{"full_name":"Mitchison, Mark T.","last_name":"Mitchison","first_name":"Mark T."},{"first_name":"Paul","last_name":"Erker","full_name":"Erker, Paul"},{"first_name":"Natalia","last_name":"Ares","full_name":"Ares, Natalia"}],"article_processing_charge":"Yes (in subscription journal)","citation":{"short":"V.

We introduce a comprehensive framework—what we believe to be the first capable of predicting instantaneous oxygen consumption (VO2) trajectories exclusively from consumer-grade wearable data. Our approach employs two complementary physiological models: (1) accurate modeling of heart rate (HR) dynamics via a physiologically constrained ordinary differential equation (ODE) and neural Kalman filter, trained on over 3 million HR observations, achieving 1-second interval predictions with mean absolute errors as low as 2.81 bpm (correlation 0.87); and (2) leveraging the principles of precise HR modeling, a novel VO2 prediction architecture requiring only the initial second of VO2 data for calibration, enabling robust, sequence-to-sequence metabolic demand estimation. Despite relying solely on smartwatch and chest-strap data, our method achieves mean absolute percentage errors of approximately 13%, effectively capturing rapid physiological transitions and steady-state conditions across diverse running intensities. Our synchronized dataset, complemented by blood lactate measurements, further lays the foundation for future noninvasive metabolic zone identification. By embedding physiological constraints within modern machine learning, this framework democratizes advanced metabolic monitoring, bridging laboratory-grade accuracy and everyday accessibility, thus empowering both elite athletes and recreational fitness enthusiasts.","lang":"eng"}],"quality_controlled":"1","day":"12","arxiv":1,"oa":1,"page":"60-77","article_processing_charge":"No","citation":{"ama":"Gahtan B, Vedula S, Samuelly Leichtag G, Kodesh E, Bronstein AM.

In contrast, the energy input of the individual components controls the behavior of synthetic or living active matter. Great progress has been made in understanding the emergent phenomena in active fluids, though their inability to resist shear forces hinders their practical use. This motivates the exploration of active solids as shape-shifting materials, yet, we lack controlled synthetic systems to devise active solids with unconventional properties. Here we build active elastic beams from dozens of active colloids and unveil complex emergent behaviors such as self-oscillations or persistent rotations. Developing tensile tests at the microscale, we show that the active beams are ultrasoft materials, with large (nonequilibrium) fluctuations. Combining experiments, theory, and stochastic inference, we show that the dynamics of the active beams can be mapped on different phase transitions which are tuned by boundary conditions. More quantitatively, we assess all relevant parameters by independent measurements or first-principles calculations, and find that our theoretical description agrees with the experimental observations. Our results demonstrate that the simple addition of activity to an elastic beam unveils novel physics and can inspire design strategies for active solids and functional microscopic machines.","lang":"eng"}],"intvolume":"        15","publication":"Physical Review X","OA_place":"publisher","OA_type":"gold","ec_funded":1,"quality_controlled":"1","day":"31"},{"volume":7,"month":"10","scopus_import":"1","publication_identifier":{"eissn":["2643-1564"]},"arxiv":1,"acknowledgement":"F.B. thanks Giuseppe de Tomasi and Oskar A.

In this work, we shift the focus to dynamical probes, specifically the steady-state spin current, to investigate transport properties in a disordered, non-Hermitian XXZ spin chain. Through exact diagonalization for small systems and tensor-network methods for larger chains, we demonstrate that the steady-state current remains finite and decays exponentially with disorder strength, showing no evidence of a transition up to disorder values far beyond the previously claimed critical point. Our results reveal a stark discrepancy between spectral indicators, which suggest localization, and transport behavior, which indicates delocalization. This highlights the importance of dynamical observables in characterizing NH MBL and suggests that traditional spectral measures may not fully capture the physics of non-Hermitian systems. Additionally, we observe a noncommutativity of limits in system size and time, further complicating the interpretation of finite-size studies. These findings challenge the existence of NH MBL in the studied model and underscore the need for alternative approaches to understanding localization in non-Hermitian settings.","lang":"eng"}],"year":"2025","ddc":["530"],"issue":"4","article_type":"original","type":"journal_article","publisher":"American Physical Society","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2025-11-30T23:02:08Z","status":"public","date_published":"2025-10-01T00:00:00Z","department":[{"_id":"MaSe"}],"date_updated":"2025-12-01T08:02:13Z","external_id":{"arxiv":["2504.02460"]},"doi":"10.1103/crwj-x7j8","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"PlanS_conform":"1","file":[{"creator":"dernst","file_id":"20715","file_name":"2025_PhysReviewResearch_Brighi.pdf","file_size":483879,"checksum":"c4e582ab64ab9f8fface70bf2fd31882","date_updated":"2025-12-01T08:00:19Z","access_level":"open_access","success":1,"content_type":"application/pdf","date_created":"2025-12-01T08:00:19Z","relation":"main_file"}],"_id":"20709","article_number":"L042014","DOAJ_listed":"1","file_date_updated":"2025-12-01T08:00:19Z","oa_version":"Published Version"}]
