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."}],"month":"11","DOAJ_listed":"1","OA_place":"publisher"},{"language":[{"iso":"eng"}],"department":[{"_id":"MiLe"}],"doi":"10.21468/SciPostPhys.19.4.093","PlanS_conform":"1","scopus_import":"1","OA_type":"diamond","has_accepted_license":"1","author":[{"id":"d7b23d3a-9e21-11ec-b482-f76739596b95","last_name":"Koutentakis","full_name":"Koutentakis, Georgios","first_name":"Georgios"},{"full_name":"Mistakidis, 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"}],"quality_controlled":"1","year":"2025","citation":{"short":"G.

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.

to produce multidecadal climate simulations, for the first time, with resolved kilometer-scale (km-scale) processes in the ocean, land, and atmosphere. 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."}],"year":"2025","quality_controlled":"1","citation":{"ieee":"H.

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."}],"date_created":"2025-11-24T14:23:22Z","publication":"Astronomy & Astrophysics","type":"journal_article","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"isi":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 702","publication_identifier":{"eissn":["1432-0746"],"issn":["0004-6361"]},"publication_status":"published"},{"month":"10","conference":{"start_date":"2025-06-23","end_date":"2025-06-26","location":"Singapore, Singapore","name":"LICS: Logic in Computer Science"},"OA_place":"repository","type":"conference","publication":"2025 40th Annual ACM/IEEE Symposium on Logic in Computer Science","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2505.21087"}],"page":"568-580","quality_controlled":"1","citation":{"ista":"Grobelna M, Kretinsky J, Weininger M. 2025.

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. We provide bounded (a.k.a. interval) VI for CSGs: it complements standard VI with a converging sequence of over-approximations and terminates once the over- and under-approximations are ϵ-close.","lang":"eng"}],"date_created":"2025-11-24T14:23:49Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publication_identifier":{"eisbn":["9798331579005"]},"corr_author":"1","arxiv":1,"_id":"20688","date_published":"2025-10-09T00:00:00Z","external_id":{"arxiv":["2505.21087"]},"status":"public","oa":1,"article_processing_charge":"No","acknowledgement":"This research was funded in part by the German Research Foundation (DFG) project 427755713 GOPro, the MUNI Award in Science and Humanities (MUNI/I/1757/2021) of the Grant Agency of Masaryk University, the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 101034413, and the ERC Starting Grant DEUCE (101077178).","publisher":"IEEE","day":"09","author":[{"full_name":"Grobelna, Marta","last_name":"Grobelna","first_name":"Marta"},{"id":"44CEF464-F248-11E8-B48F-1D18A9856A87","last_name":"Kretinsky","full_name":"Kretinsky, Jan","orcid":"0000-0002-8122-2881","first_name":"Jan"},{"first_name":"Maximilian","orcid":"0000-0002-0163-2152","full_name":"Weininger, Maximilian","last_name":"Weininger","id":"02ab0197-cc70-11ed-ab61-918e71f56881"}],"OA_type":"green","doi":"10.1109/lics65433.2025.00049","scopus_import":"1","department":[{"_id":"KrCh"}],"language":[{"iso":"eng"}],"oa_version":"Preprint","project":[{"name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413","call_identifier":"H2020"}],"ec_funded":1,"title":"Stopping criteria for value iteration on concurrent stochastic reachability and safety games","date_updated":"2025-11-26T07:34:19Z"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"eisbn":["9798331579005"]},"publication_status":"published","month":"10","OA_place":"repository","conference":{"start_date":"2025-06-23","end_date":"2025-06-26","name":"LICS: Logic in Computer Science","location":"Singapore, Singapore"},"type":"conference","publication":"2025 40th Annual ACM/IEEE Symposium on Logic in Computer Science","page":"499-512","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2504.18277"}],"year":"2025","citation":{"chicago":"Baier, Christel, Krishnendu Chatterjee, Tobias Meggendorfer, and Jakob Piribauer. “Multiplicative Rewards in Markovian Models.” In 2025 40th Annual ACM/IEEE Symposium on Logic in Computer Science, 499–512.

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"}],"author":[{"first_name":"Christel","full_name":"Baier, Christel","last_name":"Baier"},{"first_name":"Krishnendu","orcid":"0000-0002-4561-241X","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Tobias","orcid":"0000-0002-1712-2165","id":"b21b0c15-30a2-11eb-80dc-f13ca25802e1","full_name":"Meggendorfer, Tobias","last_name":"Meggendorfer"},{"full_name":"Piribauer, Jakob","last_name":"Piribauer","first_name":"Jakob"}],"day":"09","scopus_import":"1","doi":"10.1109/lics65433.2025.00044","OA_type":"green","department":[{"_id":"KrCh"}],"language":[{"iso":"eng"}],"oa_version":"Preprint","project":[{"call_identifier":"H2020","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications"}],"ec_funded":1,"title":"Multiplicative rewards in Markovian models","date_updated":"2025-11-25T07:59:25Z","corr_author":"1","arxiv":1,"_id":"20689","date_published":"2025-10-09T00:00:00Z","status":"public","external_id":{"arxiv":["2504.18277"]},"article_processing_charge":"No","acknowledgement":"This work was partly funded by the ERC CoG 863818 (ForM-SMArt), the Austrian Science Fund (FWF) 10.55776/COE12, the DFG Grant 389792660 as part of TRR 248 (Foundations of Perspicuous Software Systems), the Cluster of Excellence EXC 2050/1 (CeTI, project ID\r\n390696704, as part of Germany’s Excellence Strategy), and by the BMBF (Federal Ministry of Education and Research) in DAAD project 57616814 (SECAI, School of Embedded and\r\nComposite AI) as part of the program Konrad Zuse Schools of Excellence in Artificial Intelligence.","oa":1,"publisher":"IEEE"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","publication_identifier":{"eisbn":["9798331579005"]},"month":"10","conference":{"start_date":"2025-06-23","location":"Singapore, Singapore","name":"LICS: Logic in Computer Science","end_date":"2025-06-26"},"OA_place":"repository","publication":"2025 40th Annual ACM/IEEE Symposium on Logic in Computer Science","type":"conference","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2505.09514","open_access":"1"}],"page":"458-471","year":"2025","citation":{"ama":"Brihaye T, Chatterjee K, Mohr S, Weininger M.

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.","lang":"eng"}],"date_created":"2025-11-24T14:43:47Z","day":"09","author":[{"first_name":"Thomas","last_name":"Brihaye","full_name":"Brihaye, Thomas"},{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","last_name":"Chatterjee","first_name":"Krishnendu","orcid":"0000-0002-4561-241X"},{"full_name":"Mohr, Stefanie","last_name":"Mohr","first_name":"Stefanie"},{"id":"02ab0197-cc70-11ed-ab61-918e71f56881","full_name":"Weininger, Maximilian","last_name":"Weininger","first_name":"Maximilian","orcid":"0000-0002-0163-2152"}],"OA_type":"green","scopus_import":"1","doi":"10.1109/lics65433.2025.00041","department":[{"_id":"KrCh"}],"language":[{"iso":"eng"}],"oa_version":"Preprint","project":[{"call_identifier":"H2020","grant_number":"863818","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications"},{"name":"IST-BRIDGE: International postdoctoral program","_id":"fc2ed2f7-9c52-11eb-aca3-c01059dda49c","grant_number":"101034413","call_identifier":"H2020"}],"ec_funded":1,"title":"Risk-aware Markov decision processes using cumulative prospect theory","date_updated":"2025-11-25T07:59:49Z","corr_author":"1","arxiv":1,"_id":"20690","date_published":"2025-10-09T00:00:00Z","external_id":{"arxiv":["2505.09514"]},"status":"public","oa":1,"acknowledgement":"This project has received funding from the Fonds de la Recherche Scientifique - FNRS under grant No. T.0027.21, the Belgian National Lottery; the ERC CoG 863818 (ForM-SMArt), the Austrian Science Fund (FWF) 10.55776/COE12; the DFG project 427755713, GOPro, and the DFG research training group GRK 2428 Continuous Verification of Cyber-Physical Systems\r\n(ConVeY); the EU’s Horizon 2020 research and innovation programmes under the Marie Sklodowska-Curie grant agreement No. 101034413 (IST-BRIDGE) and the ERC Starting Grant DEUCE (101077178).","article_processing_charge":"No","publisher":"IEEE"},{"status":"public","file":[{"checksum":"1b23ad585d6f305447b54c606be0c46d","success":1,"creator":"dernst","access_level":"open_access","content_type":"application/pdf","file_size":2468843,"file_id":"20720","file_name":"2025_CommEarthEnvir_Ayala.pdf","date_created":"2025-12-01T09:10:13Z","relation":"main_file","date_updated":"2025-12-01T09:10:13Z"}],"external_id":{"isi":["001617609200003"]},"APC_amount":"3654 EUR","publisher":"Springer Nature","article_processing_charge":"Yes","acknowledgement":"This research was funded in whole or in part by the Austrian Science Fund (FWF), DOI: 10.55776/16891.

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"}],"year":"2025","quality_controlled":"1","citation":{"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"}],"year":"2025","citation":{"ista":"Wadhia V, Meier F, Fedele F, Silva R, Nurgalieva N, Craig DL, Jirovec D, Saez Mollejo J, Ballabio A, Chrastina D, Isella G, Huber M, Mitchison MT, Erker P, Ares N. 2025.

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."}],"date_created":"2025-11-30T23:02:08Z","quality_controlled":"1","year":"2025","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.

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"}],"date_created":"2025-11-30T23:02:08Z","publication":"Physical Review Research","type":"journal_article","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 7","publication_identifier":{"eissn":["2643-1564"]},"publication_status":"published"},{"publication_identifier":{"issn":["0003-0007"],"eissn":["1520-0477"]},"publication_status":"published","intvolume":" 106","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","isi":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"page":"E2143-E2169","type":"journal_article","publication":"Bulletin of the American Meteorological Society","date_created":"2025-11-30T23:02:08Z","abstract":[{"text":"Mountain glaciers offer opportunities to observe boundary layer exchanges in conditions characterized by predominantly stable stratification, thermally driven winds, and varying surface roughness. Logistical challenges involved in instrumenting glacier surfaces mean that in situ observations remain relatively scarce, limiting the use of this outdoor laboratory. The second Hintereisferner Experiment (HEFEX II) was carried out on an Austrian Alpine glacier during summer 2023. This collaborative endeavor, involving 12 institutions from Austria, France, Germany, Switzerland, and the United Kingdom, represents an unprecedented set of observations of glacier microclimate. Instrumentation on the glacier surface consisted of eight 3-m and two 5-m weather stations equipped with multilevel eddy covariance systems and auxiliary instrumentation, and eight additional lower-specification weather stations. These operated successfully for 26 days with minimal data gaps. During a 3-day intensive observational period, additional instrumentation was deployed: a short-path ultrasonic anemometer installed very close to the glacier surface; a high-speed thermal camera capturing high-resolution boundary layer heat transport at the glacier centerline on a synthetic screen; 3D sampling of the glacier boundary layer using two meteorological UAVs; and a Streamline XR Doppler lidar capturing the structure of the above-valley atmosphere. These novel datasets are valuable for improving understanding of glacier–atmosphere exchange processes, the role of glaciers in valley circulation, and how both might be affected by continued climate change and glacier recession. Here, we detail the scientific goals and implementation of the campaign, describe the general weather conditions, and present first insights into what the observations reveal about the glacier boundary layer features observed during the campaign.","lang":"eng"}],"quality_controlled":"1","year":"2025","citation":{"short":"L.

These advantages make it a tantalizing platform for studying complex phenomena in many-particle systems. In most standing-wave traps, however, particles interact via acoustic scattering forces that cause them to merge into a single dense object. Here, we introduce a complementary approach that combines acoustic levitation with electrostatic charging to assemble, adapt, and activate complex, separated many-particle systems. The key idea is to superimpose electrostatic repulsion on the intrinsic acoustic attraction, rendering a so-called “mermaid” potential where interactions are attractive at short range and repulsive at long range. By controlling the attraction–repulsion balance, we can levitate expanded structures where all particles are separated, collapsed structures where they are in contact, and hybrid ones consisting of both expanded and collapsed components. We find that collapsed and expanded structures are inherently stable, whereas hybrid ones exhibit transient stability governed by acoustically unstable dimers. Furthermore, we show how electrostatics allow us to adapt between configurations on the fly, either by quasistatic discharge or discrete up/down charge steps. Finally, we demonstrate how large structures experience selective energy pumping from the acoustic field—thrusting some particles into motion while others remain stationary—leading to complex dynamics including coupled rotations and oscillations.

This effect has however never been quantified for more than a few glaciers and the impact on the future evolution of glaciers is unclear. We coupled an avalanche and a glacier model to estimate the contribution of avalanches to the accumulation of all glaciers in the world and how this affects their evolution throughout the 21st century. Globally, 3% of the snow accumulation on glaciers comes from avalanches and 1% is removed by avalanches. This net contribution varies between regions and glaciers, with a maximum of 15% for New Zealand. Accounting for avalanches modifies the altitudinal pattern of glacier mass balance and the projected evolution of individual glaciers. The main effects include (1) a longer persistence of small glaciers, with for example three times more ice retained by glaciers smaller than 1 km2 in Central Europe under a low-emission scenario, and (2) an increased sensitivity of high-elevation accumulation zones to future warming. We anticipate the relative influence of avalanches to increase in the future and advocate for a better monitoring of this process and representation in glacier models.","lang":"eng"}],"citation":{"short":"M.
