The central question is whether a dynamical system can be determined, up to a natural conjugacy, from its spectrum. We consider three related spectra: the length spectrum, the action spectrum, and the Lyapunov spectrum.\r\n\r\nThe first part of the thesis concerns Liouville metrics on the two-dimensional torus. It is a long-standing folklore conjecture that Liouville metrics are the only integrable metrics on the torus. We prove a length-spectral rigidity result for linear conformal deformations of Liouville metrics by exploiting the dynamical properties of the rational tori -- analogues of the resonant convex caustics in billiards. We also establish a complementary classification result showing that marked-length-isospectral Liouville metrics are characterized by rearrangements of the one-dimensional functions appearing in their conformal factors, generalizing a theorem of Abbondandolo-Mazzucchelli. In particular, the second result gives nonrigidity examples within the class of Liouville metrics.\r\n\r\nThe second part of the thesis studies the standard map from the viewpoint of action and Lyapunov spectra. We construct nontrivial deformations of the standard map which preserve the symplectic actions (respectively, the Lyapunov exponents) of infinitely many periodic orbits accumulating on an invariant curve. The proof combines a resonant normal form construction with Picard iteration schemes to obtain a sequence of periodic orbits accumulating on an invariant curve with a Liouville rotation number. Within the resonant normal forms we capture the dependence of these periodic orbits on the resonant Fourier coefficients of the dynamics on the invariant curve and, using the contraction mapping principle, obtain a suitable deformation achieving the prescribed spectral data associated with this sequence of orbits. The result can be viewed as a symplectic twist-map analogue of a length-spectral nonrigidity phenomenon for Riemannian manifolds and convex billiards, and it motivates the existence problem for similar 'partially length-isospectral' deformations of strictly convex billiard tables.\r\n","lang":"eng"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_created":"2026-07-08T12:44:31Z","ddc":["515"],"publication_identifier":{"issn":["2663-337X"]},"day":"11","oa_version":"Published Version","alternative_title":["ISTA Thesis"],"supervisor":[{"first_name":"Vadim","id":"FE553552-CDE8-11E9-B324-C0EBE5697425","orcid":"0000-0002-6051-2628","full_name":"Kaloshin, Vadim","last_name":"Kaloshin"}],"corr_author":"1","citation":{"short":"Y.

Spatial polarization of organelles within cells, including endo-lysosomes, is a prerequisite of migration. However, how ultrastructural polarization is linked to the signaling requirements governing T cell migration remains unknown. Here we show that signaling molecules generated by endo-lysosome-localized kinases regulate velocity of amoeboid migration. Specifically, imaging of T cells identifies accumulation of endo-lysosomes decorated with the lipid kinases VPS34–PIKfyve at the uropod of polarized cells. Activity of VPS34 and PIKfyve regulates speed, but not directedness, of migrating T cells. Mechanistically, PI(3,5)P2 generated by the sequential action of VPS34 and PIKfyve, mediates Ca2+ efflux from lysosomes via the mucolipin TRP cation channel 1 (TRPML1), thus controlling activity of myosin IIA and hence the generation of propulsive force through retrograde actin flow. The VPS34–PIKfyve kinases also regulate velocity of myeloid cells, as well as of the amoeba Dictyostelium discoideum – establishing the axis as an evolutionarily conserved speed control system of amoeboid cell migration.","lang":"eng"}],"supplementarymaterial":"yes","external_id":{"pmid":["42414599"]},"date_created":"2026-07-19T22:01:48Z","article_processing_charge":"Yes (via OA deal)","author":[{"full_name":"Dehio, Philippe G","id":"b769738e-a003-11ee-b1b8-9030316e0d59","first_name":"Philippe G","last_name":"Dehio"},{"last_name":"Michard","full_name":"Michard, Céline","first_name":"Céline"},{"last_name":"Yam-Puc","full_name":"Yam-Puc, Juan Carlos","first_name":"Juan Carlos"},{"last_name":"Martí I Líndez","first_name":"Adrià Arnau","full_name":"Martí I Líndez, Adrià Arnau"},{"last_name":"Jandke","first_name":"Anett","full_name":"Jandke, Anett"},{"last_name":"Unterstab","first_name":"Gunhild","full_name":"Unterstab, Gunhild"},{"last_name":"Fabre","full_name":"Fabre, Lucien","first_name":"Lucien"},{"full_name":"Sauteur, Loïc","first_name":"Loïc","last_name":"Sauteur"},{"last_name":"Artinger","first_name":"Marc","full_name":"Artinger, Marc"},{"last_name":"Legler","first_name":"Daniel F.","full_name":"Legler, Daniel F."},{"orcid":"0000-0002-6620-9179","full_name":"Sixt, Michael K","first_name":"Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt"},{"last_name":"Schaefer","full_name":"Schaefer, Thorsten","first_name":"Thorsten"},{"full_name":"Wymann, Matthias P.","first_name":"Matthias P.","last_name":"Wymann"},{"first_name":"Klaus","full_name":"Okkenhaug, Klaus","last_name":"Okkenhaug"},{"first_name":"Thierry","full_name":"Soldati, Thierry","last_name":"Soldati"},{"id":"3C23B994-F248-11E8-B48F-1D18A9856A87","first_name":"Matthias","orcid":"0000-0001-8599-1226","full_name":"Mehling, Matthias","last_name":"Mehling"},{"first_name":"Christoph","full_name":"Hess, Christoph","last_name":"Hess"}],"acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"OA_type":"gold","das_tickbox":"1","publisher":"Springer Nature","year":"2026","researchdata_availability":"yes","month":"07","title":"A conserved VPS34-PIKfyve-TRPML1-myosin II axis regulates the speed of amoeboid cell migration","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s44319-026-00861-x"}],"doi":"10.1038/s44319-026-00861-x","department":[{"_id":"MiSi"}],"status":"public"},{"acknowledgement":"We acknowledge Prof. Dolf Weijers (Wageningen University), Prof.Karin Schumacher (Heidelberg University), Prof. Yohann Boutt ´e(Universit ´e de Bordeaux), and Prof. Jinbo Shen (Zhejiang A&FUniversity) for providing published plasmids and Arabidopsislines.

In this study, we employed forward genetic screening to identify Arabidopsis mutants with defective hypocotyl gravitropism and isolated the short and agravitropic hypocotyl in dark1 (sad1) mutant, which carries a point mutation (G110E) in the SAC1 gene encoding a phosphoinositide phosphatase. Deficiency of SAC1 disrupted gravity-induced polar localization of PIN3 in endodermal cells, impairing auxin redistribution and leading to hypocotyl gravitropism defects. Subcellular localization analysis revealed that SAC1 is partially localized to the PVC/tonoplast and participates in late endosomal trafficking. The sac1 mutation leads to abnormal vacuolar morphology, which is associated with defects in amyloplast sedimentation during the gravitropic response in Arabidopsis shoots. We further revealed that SAC1 interacts with GRV2, a key regulator of the late endocytic pathway, and that both proteins cooperatively regulate shoot gravitropism. In summary, this study identified SAC1 as a regulator of shoot gravitropism, revealing its important role in modulating vacuolar homeostasis, amyloplast sedimentation, PIN3 trafficking, and auxin distribution. These findings provide insights into the molecular mechanisms linking membrane transport to environmental adaptation in plants.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","oa_version":"None","publication_identifier":{"eissn":["1365-313X"],"issn":["0960-7412"]},"day":"01","citation":{"chicago":"Sun, Lianghanxiao, Wenxin Jia, Yanbo Mao, Xin Li, Mengjuan Kong, Ji She, Jiří Friml, and Shutang Tan. “Regulation of Shoot Gravitropism and Branching Angle by the GRV2-SAC1 Axis in Arabidopsis.” The Plant Journal.

We introduce an alternative experimental probe, capturing microwave radiation across all three regimes, using a two-dimensional array of superconductor-semiconductor hybrid Josephson junctions as a model system. Our approach allows calibration of the sample’s circuit parameters and provides isolation from measurement back-action effects. We measure the radiation temperature of the anomalous metal and find that it is hotter than both the quantum-critical and insulating regimes. We further show that the anomalous metallic regime is more susceptible to additional heating than other regimes, explaining its emergence in otherwise thermalized systems.

X-ray binaries exhibit complex variability patterns studied in the power spectrum. These include the broadband noise (BBN)\r\ncomponents and various types of narrow components called quasi-periodic oscillations (QPOs). There is currently no consensus about\r\nwhat determines the presence or absence of the BBN or what generates the QPOs. Many believe that QPO generation is due to framedragging effects caused by Lense–Thirring torques.\r\nAims. We investigated the potential impact of frame-dragging effects on the accretion disk itself. In particular, we focused on its\r\nimpact on the observed variability and on the presence (and types) of associated QPOs.\r\nMethods. We made analytical estimates to assess the potential presence of a geometric warp in the inner accretion disk during state\r\ntransitions.\r\nResults. We show that the presence of a warp can modify the spectral-timing properties in a way that matches the observed transition\r\nbetween QPO types during outbursts. We also discuss the peculiar case of Cyg X-1, as well as how the hard-to-soft transition could\r\nbe driven by the warp itself.\r\nConclusions. The (expected) emergence of a warp provides a consistent explanation for the evolution of both the BBN and the QPO\r\nproperties during state transitions. This offers a first path toward unifying the variability of black hole X-ray binaries.","lang":"eng"}],"supplementarymaterial":"yes","oa_version":"Published Version","arxiv":1,"PlanS_conform":"1","day":"01","publication_identifier":{"eissn":["1432-0746"],"issn":["0004-6361"]},"acknowledgement":"GM acknowledges support from the Polish National Science Center grant 2023/48/Q/ST9/00138 and the Academy of Finland grant 355672.

To ensure fairness at runtime, it is necessary to account for past decisions, information neglected by conventional, static classifiers. Traditional fairness shields enforce runtime fairness abruptly, by intervening deterministically whenever a sequence of decisions violates the target for a running fairness measure. This motivates our main conceptual contribution: energy shields. An energy shield is a novel, lightweight, adaptive controller that monitors a sequence of decisions and intervenes probabilistically to ensure runtime fairness smoothly, by utilizing physics-inspired energy functions to nudge the sequence toward fairness: the more unfair the decisions, the stronger the nudging force becomes. This makes energy shields the first fairness shields to provide both short-term safety and long-term liveness guarantees. Safety ensures that the running fairness measure stays within a running target interval with high probability, and liveness ensures that the limit of the fairness measure lies within the limit target interval. Intuitively, the short-term specifies the tolerated fairness values and the long-term specifies the desired fairness values. We also provide a synthesis procedure for constructing the least intrusive energy shield for a given target specification, and demonstrate its efficiency experimentally. We evaluate our energy shields against existing fairness shields through the lens of short- and long-term fairness."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","arxiv":1,"oa_version":"Published Version","day":"01","ec_funded":1,"acknowledgement":"This work has been supported by the European Research Council under Grant No.: ERC-2020-AdG 101020093.","scopus_import":"1","date_updated":"2026-07-22T06:15:56Z","file_date_updated":"2026-07-16T09:23:15Z","file":[{"checksum":"21e648ea3b529f0df7545ad4b31b0ef4","access_level":"open_access","relation":"main_file","file_name":"2026_ACMFACCT_Cano.pdf","date_created":"2026-07-16T09:23:15Z","file_id":"22348","success":1,"date_updated":"2026-07-16T09:23:15Z","content_type":"application/pdf","creator":"dernst","file_size":3129128}],"_id":"22321"},{"das_tickbox":"1","publisher":"Springer Nature","year":"2026","volume":22,"doi":"10.1007/s44393-026-00024-0","department":[{"_id":"FrPe"}],"status":"public","researchdata_availability":"no","month":"06","has_accepted_license":"1","title":"Multiscale aspects of an extreme precipitation event over Nepal in September 2024","language":[{"iso":"eng"}],"article_processing_charge":"Yes","author":[{"last_name":"Fujinami","full_name":"Fujinami, Hatsuki","first_name":"Hatsuki"},{"last_name":"Takahashi","full_name":"Takahashi, Nobuhiro","first_name":"Nobuhiro"},{"full_name":"Kanamori, Hironari","first_name":"Hironari","last_name":"Kanamori"},{"id":"daa9e17a-f2c2-11ef-b968-915e836dea45","first_name":"Yota","full_name":"Sato, Yota","last_name":"Sato"},{"last_name":"Sunako","full_name":"Sunako, Sojiro","first_name":"Sojiro"},{"first_name":"Masaya","full_name":"Kato, Masaya","last_name":"Kato"},{"last_name":"Higuchi","first_name":"Atsushi","full_name":"Higuchi, Atsushi"},{"full_name":"Kadel, Indira","first_name":"Indira","last_name":"Kadel"},{"last_name":"Shrestha","first_name":"Dibas","full_name":"Shrestha, Dibas"},{"first_name":"Rijan B.","full_name":"Kayastha, Rijan B.","last_name":"Kayastha"},{"last_name":"Fujita","full_name":"Fujita, Koji","first_name":"Koji"}],"OA_type":"gold","scopus_import":"1","acknowledgement":"This work was supported by the Japan Society for the Promotion of Science (JSPS) (KAKENHI Grants: 22H00176, 22H00033, 22H00037, and 23KK0064).

This study examined the multiscale processes contributing to this extreme precipitation event, focusing on intraseasonal oscillations, synoptic-scale circulations, and mesoscale cloud/precipitation systems. A quasi-biweekly intraseasonal oscillation dominated over South Asia during the event, featuring a monsoon low-pressure system over the Indian Peninsula and an anticyclone to its east, both propagating westward. The pressure gradient between them sustained strong southerly moisture transport toward the Himalayas, establishing a persistently humid environment and orographic lift along the southern slopes. In contrast to reports of previous extreme precipitation events in Nepal, the atmospheric circulation responsible for the 2024 event was primarily of tropical origin, with minimal influence from the midlatitudes. Characteristic mesoscale cloud/precipitation systems also developed around the Himalayas. The highest daily precipitation during the event was recorded on 27 September; stratiform systems with relatively modest storm top heights developed over the southern slopes, generating surface precipitation rates of > 100 mm h− 1 through warm-rain processes. Rain gauges across the glacierized basin (3500–5000 m asl) recorded exceptionally high daily and hourly precipitation rates, highlighting the extension of intense rainfall to unusually high elevations."}],"article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2026-06-14T22:01:42Z","ddc":["550"],"day":"04","publication_identifier":{"eissn":["1349-6476"]},"PlanS_conform":"1","oa_version":"Published Version","intvolume":" 22","citation":{"ama":"Fujinami H, Takahashi N, Kanamori H, et al.

Ever more powerful edge devices, such as smartphones, have become\r\nubiquitous in most societies on earth. Through text typed, photos taken and apps used,\r\nthese devices, which we refer to as clients, generate enormous amounts of high quality and\r\ncomplex data. Moreover, the nature of these devices means the data they generate is often\r\nsensitive and privacy concerns prevent it being gathered and stored in a central location. This\r\npresents a challenge to the modern machine learning paradigm that requires central access\r\nto large amounts of data. Federated learning (FL) has emerged as one of the answers to\r\nthis problem. Rather than bringing the data to the model, FL sends the model to the data.\r\nModel training takes place on device, with periodically synchronized updates, allowing data to\r\nremain locally stored. While this approach offers significant privacy advantages it comes with\r\nits own set of unique challenges. These include: data heterogeneity, the notion that different\r\ndevices generate data in distinct ways which can negatively impact training dynamics; systems\r\nheterogeneity, meaning that different devices may have differing hardware specifications; high\r\ncommunication costs, which are induced by the repeated transferring of models over the\r\nnetwork and low device computational power, which limits the use of larger models on device.\r\nIn this thesis we present a range of methods for federated learning. We focus primarily on\r\nthe challenge of data heterogeneity, though the methods presented are designed to be well\r\nadapted to the other challenges of a federated setting, such as the constraints of limited\r\ncompute and communication overhead. We first present a method for explicitly modeling client\r\ndata heterogeneity. The approach formulates clients as samples from a certain probability\r\ndistribution and infers the parameters of this distribution from the available training clients.\r\nThis learned distribution then represents the heterogeneity present among the clients and can\r\nbe sampled from in order to create new simulated clients that are similar to the real clients we\r\nhave observed so far. Following this we present two methods for directly dealing with data\r\nheterogeneity through personalization. Highly heterogeneous client data distributions can mean\r\nthat learning a single global model becomes suboptimal, and some form of personalization of\r\nmodels to each individual client is required. Our approaches are based around hypernetworks,\r\nwhich we use to generate personalized model parameters without the need for additional\r\ntraining or finetuning. In the first approach we focus on generating full parameterizations of\r\nclient models using learned embeddings of client data and labels, with a hypernetwork located\r\non the central server. In the second approach we address the more challenging scenario where\r\nwe want to generate a personalized model for a client without any label information. The\r\nhypernetwork is trained to generate a low dimensional representation of a client’s personalized\r\nmodel parameters, allowing it to be transferred to and run on the client devices. In our final\r\npresented method, we change our focus and rather than aim to directly address the challenge\r\nof data heterogeneity, we instead ensure we are unaffected by it. This is done in the context\r\nof k-means clustering and we present a method for federated clustering with a focus on added\r\nprivacy guarantees.","lang":"eng"}],"oa_version":"Published Version","day":"09","publication_identifier":{"issn":["2663-337X"]},"citation":{"short":"J.A.

It considers how continuous manifolds relate to their discrete analogues, how topological structures evolve in persistence vineyards, and how tools from topological data analysis can illuminate problems in mathematical physics. Central to this exploration is the question of how structure, both geometric and topological, persists or changes under approximation, sampling, or deformation. The work develops new approaches to skeletal and grid-based representations of surfaces, reveals the full expressive capacity of persistence vineyards, and applies topological methods to the longstanding problem of equilibria in electrostatic fields. These threads braid together into a broader understanding of how topology and geometry inform one another across theory, computation, and application."}],"oa_version":"Published Version","day":"21","publication_identifier":{"issn":["2663-337X"]},"related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"20260"},{"status":"public","relation":"part_of_dissertation","id":"21051"},{"status":"public","id":"21050","relation":"part_of_dissertation"}]},"degree_awarded":"PhD","acknowledgement":"The research presented in this thesis was funded by the DFG Collaborative Research\r\nCenter TRR 109, ‘Discretization in Geometry and Dynamics’.\r\n","date_updated":"2026-07-22T06:33:54Z","file":[{"file_name":"2025_Fillmore_Christopher_Thesis.pdf","relation":"main_file","date_created":"2026-01-26T19:44:46Z","checksum":"4c0889130095c31d4e5088c5b8dfd607","access_level":"open_access","file_size":55954297,"creator":"cfillmor","file_id":"21046","content_type":"application/pdf","date_updated":"2026-01-30T11:40:09Z"},{"file_size":166080788,"creator":"cfillmor","file_id":"21047","date_updated":"2026-01-26T19:46:20Z","content_type":"application/x-zip-compressed","relation":"source_file","file_name":"Thesis.zip","date_created":"2026-01-26T19:46:20Z","access_level":"closed","checksum":"d69afb71d82ab98f856886126ee7303a"}],"file_date_updated":"2026-01-30T11:40:09Z","_id":"21021","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"ScienComp"}],"author":[{"id":"35638A5C-AAC7-11E9-B0BF-5503E6697425","first_name":"Christopher D","full_name":"Fillmore, Christopher D","last_name":"Fillmore"}],"article_processing_charge":"No","status":"public","department":[{"_id":"GradSch"},{"_id":"HeEd"},{"_id":"UlWa"}],"doi":"10.15479/AT-ISTA-21021","title":"Braiding geometry and topology to study shapes and data","language":[{"iso":"eng"}],"has_accepted_license":"1","month":"01","publisher":"Institute of Science and Technology Austria","year":"2026"},{"intvolume":" 132","citation":{"mla":"Edelsbrunner, Herbert, et al. “Counting Equilibria of the Electrostatic Potential.” Proceedings of the London Mathematical Society, vol. 132, no. 5, e70163, Wiley, 2026, doi:10.1112/plms.70163.","chicago":"Edelsbrunner, Herbert, Christopher D Fillmore, and Goncalo Oliveira. “Counting Equilibria of the Electrostatic Potential.” Proceedings of the London Mathematical Society.

In this article, we give the best upper bound known to date on the number of zeroes of the electric field, and construct a counterexample to Conjecture 1.8 by Gabrielov, Novikov, and Shapiro that the number of equilibria cannot exceed those of the distance function defined by the unit point charges. Finally, we note that it is quite possible that Maxwell's quadratic upper bound is not tight, so it is prudent to find lower bounds. Hence, we also explore examples and construct configurations of charges achieving the highest ratios of the number of electric field zeroes by point charges found to this day."}],"external_id":{"arxiv":["2501.05315"]},"date_created":"2026-05-31T22:02:13Z","day":"01","publication_identifier":{"issn":["0024-6115"],"eissn":["1460-244X"]},"oa_version":"Preprint","arxiv":1,"issue":"5","article_processing_charge":"No","author":[{"last_name":"Edelsbrunner","first_name":"Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","full_name":"Edelsbrunner, Herbert","orcid":"0000-0002-9823-6833"},{"last_name":"Fillmore","first_name":"Christopher D","id":"35638A5C-AAC7-11E9-B0BF-5503E6697425","full_name":"Fillmore, Christopher D"},{"last_name":"Oliveira","id":"58abbde8-f455-11eb-a497-98c8fd71b905","first_name":"Goncalo","full_name":"Oliveira, Goncalo"}],"OA_type":"green","publisher":"Wiley","year":"2026","volume":132,"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2501.05315","open_access":"1"}],"department":[{"_id":"HeEd"},{"_id":"TaHa"}],"doi":"10.1112/plms.70163","status":"public","month":"05","title":"Counting equilibria of the electrostatic potential","language":[{"iso":"eng"}]},{"corr_author":"1","citation":{"ama":"Elkner MM.

However, existing datasets focus mainly on mainstream social media platforms whose structures are shaped notably by algorithmic recommendations. This raises an important question: would alternative, decentralized social networks exhibit different properties? We address this by studying the Fediverse; a collection of decentralized social networks (such as Mastodon and Lemmy). These platforms differ fundamentally from for-profit social media, notably in decentralization and absence of recommendation algorithms, which may yield distinct graph structures. We introduce Fedivertex, a dataset of over 400 graphs from seven decentralized networks, collected weekly over six months. The dataset, released with a companion Python package to facilitate its use, supports research on temporal and structural aspects of decentralized social networks. In particular, we benchmark applications to decentralized machine learning and community detection.","lang":"eng"}],"department":[{"_id":"ChLa"}],"status":"public","date_created":"2026-05-24T22:01:32Z","article_processing_charge":"No","conference":{"name":"WWW: Web Conference","start_date":"2026-06-29","end_date":"2026-07-03","location":"Dubai"},"author":[{"last_name":"Damie","full_name":"Damie, Marc","first_name":"Marc"},{"full_name":"Cyffers, Edwige Audrey Lucienne","id":"20d4c299-977a-11ef-ae55-98b15ac64a57","first_name":"Edwige Audrey Lucienne","last_name":"Cyffers"}],"citation":{"short":"M.

However, it suffers from poor cycle life associated with the rock-salt phase transformation. This study presents a straightforward synthesis approach to enhance the electrochemical performance of LiNi0.5Mn1.5O4 through a synergistic solid-state modification with LiF and AlF3. This dual modification promotes rapid Li⁺ diffusion, enables near-complete delithiation/lithiation, approaching the theoretical capacity of disordered LiNi0.5Mn1.5O4, and, more importantly, effectively mitigates the formation of the rock-salt phase, thereby enhancing structural stability, as confirmed by operando X-ray absorption spectroscopy (XAS) and synchrotron X-ray diffraction (SXRD). As a result, the optimized LiNi0.5Mn1.5O4 (10 mg AlF3 + 30 mg LiF) delivers high reversible capacities of 142.1, 139.1, 129.2, 121.6, 110.3, 93.5, and 76.1 mAh∙g−1 at 0.2C, 0.5C, 1.0C, 2.0C, 3.0C, 4.0C, and 5.0C, respectively. Full cells using graphite as the anode and a high-loading cathode exhibit excellent cycling performance. They retain 80% of their capacity after 200 cycles at 0.5C within a voltage window of 3.5–4.9 V with cathode loading of 11 mg∙cm−2. The findings of this study will significantly advance high-power LiNi0.5Mn1.5O4 materials, offering improved battery life and thereby enhancing their potential for practical applications."}],"file_date_updated":"2026-07-23T06:15:51Z","file":[{"file_size":6353217,"creator":"dernst","content_type":"application/pdf","date_updated":"2026-07-23T06:15:51Z","success":1,"file_id":"22387","date_created":"2026-07-23T06:15:51Z","file_name":"2026_AdvancedScience_Chang.pdf","relation":"main_file","access_level":"open_access","checksum":"37adc3eff9ad9f8f9b55cfe66883f36d"}],"DOAJ_listed":"1","date_updated":"2026-07-23T06:18:43Z","_id":"20851","acknowledgement":"This work was supported by the European Commission-financed project IntelLigent (HORIZON-CL5-2021-D2-01-02) with project ID number 101069765.

Yet, how temperature regulates migration dynamics at the single-cell level has remained poorly understood. Using zebrafish embryos and mouse tissue explants, we found that temperature positively regulates leukocyte migration speed, exploration, and arrival frequencies to wounds and lymph vessels. Complementary 2D and 3D cultures revealed that this thermokinetic control of cell migration is conserved across immune cell types, independently of the 3D tissue environment. By applying precise (sub-)cellular temperature modulation, we identified a rapid and reversible thermo-response that depends on myosin II activity. Small physiological increases in temperature (1°C –2°C), as present during fever-like conditions, profoundly increased immune responses by accelerating arrival times at lymphatic vessels and tissue wounds. These findings identify myosin-II-dependent actomyosin contractility as a critical mechanical structure regulating single-cell thermo-adaptability, with physiological implications for tuning the speed of immune responses in vivo."}],"supplementarymaterial":"yes","ddc":["570"],"external_id":{"pmid":["41192429"]},"date_created":"2025-12-28T23:01:27Z","day":"11","publication_identifier":{"issn":["1534-5807"],"eissn":["1878-1551"]},"oa_version":"Published Version","PlanS_conform":"1","intvolume":" 61","citation":{"short":"I.

Here, we expand DESC to water-soluble azopolymers obtained by RAFT polymerization and systematically investigate the interplay between the polymer structure and DESC efficiency. Using this approach, we achieved as much as 85% of the direct photoexcitation (UV) switching efficiency, while utilizing low-energy (yellow) light.
