Here, we identify a female-selective corticosterone-mediated microglia-neuron interaction during ketamine anesthesia recovery, absent in males. This microglia-neuron interaction induces plastic and functional neuronal changes, as evidenced by increased mEPSC frequency, which was occluded upon microglia depletion. We showed that this process is driven through up-regulation of the stress-responsive co-chaperone Fkbp5 mRNA and its protein, Fkbp51, in female microglia. Fkbp5/Fkbp51 is a key intermediary in a corticosteroid-induced stress response, and its involvement points toward a critical interface between endocrine signaling and microglia. To counteract the observed ketamine anesthesia-mediated increase in blood corticosterone during recovery, we removed the primary source of corticosterone by adrenalectomy. Close microglia-neuron interaction was reduced and increased again following corticosterone injection. Our findings identify a sex-specific microglia-mediated mechanism of neuronal plasticity during anesthesia recovery, driven by corticosterone, thereby enhancing our understanding of sex differences in brain function.","lang":"eng"}],"file_date_updated":"2026-09-22T06:50:16Z","file":[{"creator":"dernst","file_size":4556377,"relation":"main_file","file_id":"22980","date_updated":"2026-09-22T06:50:16Z","access_level":"open_access","success":1,"content_type":"application/pdf","date_created":"2026-09-22T06:50:16Z","file_name":"2026_ScienceAdv_Venturino.pdf","checksum":"715a1f35a0805be85ef90556205a2cbc"}],"publication_identifier":{"eissn":["2375-2548"]},"citation":{"chicago":"Venturino, Alessandro, Amin Alam, Thomas Negrello, Kelly Jin, Cindy T.

In this work, we demonstrate that ion transport within a two-dimensional graphite nanoslit can be rationally engineered to achieve a bipolar, pressure-sensitive response without any structural deformation. The mechanosensitivity arises from the selective charging of one channel inlet, which acts as a reversible source of mobile charge carriers. These excess ions can then be advected in or out of the channel by the pressure-driven water flow, thereby modulating the ionic conductance. This mechanism is captured through a comprehensive electrohydrodynamic model that analytically accounts for coupled diffusion, convection, surface transport, diffusio-osmosis, and interfacial slippage, both inside and outside the nanoslit. The theoretical framework quantitatively reproduces the experimental data, showing that a simple surface charge pattern can give rise to complex, pressure-dependent conductance. These findings reveal how rich nonlinear couplings at the nanoscale can be harnessed to design adaptive, bioinspired nanofluidic systems, exemplified here by ionic pressure sensors."}],"publication":"Science Advances","ddc":["530"],"tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"oa_version":"Published Version","issue":"31","acknowledgement":"We acknowledge support from eRc project n-AQUA, grant agreement 101071937.

The associated billiard map is dissipative, thus it admits a compact invariant set, the so-called Birkhoff attractor.

We prove that (a) for strong dissipation, the Birkhoff attractor is a normally contracted graph over the zero section; (b) for mild dissipation, the Birkhoff attractor within a centrally symmetric domain is an indecomposable continuum whose restricted dynamics has positive topological entropy.

This article examines how the Spanish-speaking community has responded to this gap through the creation of the Simposio de Estudiantes Hispanohablantes de Bioinformática y Biología Computacional (SEH2Bioinfo), a collective initiative that transforms language into a tool for inclusion and collaboration. Drawing on a historical review of the use of Spanish in scientific communication and an analysis of the two editions of SEH2Bioinfo (2022 and 2025), complemented by surveys of more than 1500 participants, we explore the effects of language on confidence, participation, and academic visibility. The findings show that Spanish can serve as a space for training and mentorship without compromising rigor, while simultaneously strengthening international networks and promoting open science. The growth of SEH2Bioinfo, its collaborative approach, and its intercontinental reach establish the symposium as a model for linguistic equity in scientific practice. Its experience demonstrates that expanding linguistic diversity in bioinformatics is not only possible but essential to building a global scientific community that is fairer, more connected, and representative.","lang":"eng"}],"supplementarymaterial":"no","volume":6,"scopus_import":"1","article_type":"original","day":"06","ddc":["570"],"publication":"Bioinformatics Advances","oa_version":"Published Version","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"language":[{"iso":"eng"}],"acknowledgement":"We acknowledge the sponsors who made the SEH2Bioinfo possible, the organizers from the various Spanish-speaking RSGs, and\r\nthe collaborators who contributed to dissemination, logistics,\r\nand other essential tasks for its execution.

Our scheme utilizes coherent averaging across a chain of \r\n optomechanical cavities, unidirectionally coupled via a laser beam. As the beam passes through the cavities, it accumulates phase shifts induced by a common external force acting on the mechanical elements. Remarkably, this fully classical approach achieves the sensitivity scaling typically associated with quantum-enhanced protocols, providing a robust and experimentally feasible route to precision sensing. Potential applications range from high-sensitivity gravitational field measurements at the Large Hadron Collider to probing dark matter interactions and detecting gravitational waves. This work opens a new pathway for leveraging coherent light-matter interactions for force sensing.","lang":"eng"}],"volume":28,"supplementarymaterial":"yes","ddc":["530"],"publication":"New Journal of

The report is organized into eight thematic areas spanning core methodologies and major application domains, including enzymes, therapeutics, detection, synthetic biology, and materials. Contributions from experts across these areas highlight both the historical foundations and recent advances in their respective fields, with particular emphasis on the growing influence of machine learning and artificial intelligence-based methods. Emerging from this broad overview is a central message: protein engineering appears to be entering a golden age, defined by a rapidly accelerating pace of progress, even as significant challenges in design, screening, and real-world application remain. Looking ahead, the continued integration of computational and experimental strategies is poised to further accelerate the impact of protein engineering across an expanding range of economically and societally important sectors, from therapeutics and molecular imaging to diagnostics, plastic recycling, and industrial chemistry."}],"volume":39,"supplementarymaterial":"no"},{"author":[{"first_name":"Jonathan A","id":"e499926b-f6e0-11ea-865d-9c63db0031e8","full_name":"Scott, Jonathan A","last_name":"Scott"}],"oa":1,"corr_author":"1","publisher":"Institute of Science and Technology Austria","degree_awarded":"PhD","_id":"21198","status":"public","has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","doi":"10.15479/AT-ISTA-21198","year":"2026","acknowledged_ssus":[{"_id":"ScienComp"}],"date_updated":"2026-10-01T09:29:03Z","title":"Data heterogeneity and personalization in federated learning","publication_status":"published","department":[{"_id":"GradSch"},{"_id":"ChLa"}],"OA_place":"publisher","month":"02","article_processing_charge":"No","date_created":"2026-02-09T14:59:53Z","supervisor":[{"orcid":"0000-0001-8622-7887","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","first_name":"Christoph","full_name":"Lampert, Christoph","last_name":"Lampert"}],"related_material":{"record":[{"relation":"part_of_dissertation","id":"21207","status":"public"},{"relation":"part_of_dissertation","id":"20819","status":"public"},{"status":"public","relation":"part_of_dissertation","id":"17411"},{"status":"public","relation":"part_of_dissertation","id":"18120"}]},"type":"dissertation","date_published":"2026-02-09T00:00:00Z","fulldoi":"https://doi.org/10.15479/AT-ISTA-21198","doi_confirm":"1","page":"158","ddc":["005"],"project":[{"grant_number":"COE12","name":"Bilateral Artificial Intelligence (Lampert)","_id":"d8f03aaa-b035-11f1-8588-d5147fa879e0"}],"day":"09","alternative_title":["ISTA Thesis"],"abstract":[{"text":"In recent years there has been a massive increase in the amount of data generated in a\r\ndecentralized manner. 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"}],"file_date_updated":"2026-02-27T10:25:41Z","file":[{"file_size":272379252,"relation":"source_file","file_id":"21298","creator":"jscott","access_level":"closed","date_updated":"2026-02-17T11:46:22Z","content_type":"application/zip","file_name":"2026_Scott_Jonathan_Thesis_Source.zip","checksum":"121c1d968bd86f3630aa7e81d5bbbcb0","date_created":"2026-02-17T11:46:22Z"},{"content_type":"application/pdf","date_created":"2026-02-27T10:25:41Z","checksum":"6e3e08ba474bbee8511cc8a839ab2077","file_name":"2026_Jonathan_Scott_Thesis.pdf","creator":"jscott","relation":"main_file","file_id":"21366","file_size":15220298,"date_updated":"2026-02-27T10:25:41Z","success":1,"access_level":"open_access"}],"publication_identifier":{"issn":["2663-337X"]},"citation":{"mla":"Scott, Jonathan A. <i>Data Heterogeneity and Personalization in Federated Learning</i>.

To that end, many methods have been proposed to prune models by reducing their number of nonzero parameters. Additionally, parameter-efficient fine-tuning, in which a much smaller number of parameters than the total contained in the model is updated during training, has become very popular, especially in the space of Large Language Models. At the same time, the increasingly routine deployment of machine learning in real-world applications has spurred a drive to make them more trustworthy - in the sense of, among other things, being unbiased, interpretable, and editable. In this thesis, we examine the interplay between efficiency and trustworthiness.\r\n\r\nFirst, we analyze the effects of model pruning on bias in computer vision models, demonstrating that increased sparsity leads to greater bias, largely as a function of increased model uncertainty in marginal cases. Based on this observation, we propose several bias mitigation techniques. Then, we demonstrate that example-specific model pruning can improve model interpretation methods while improving pruning efficiency to make example-specific model pruning feasible in real time. Then, we investigate the effectiveness of parameter-efficient and data-efficient model personalization via fine-tuning, demonstrating that it is highly feasible with very small computational and data resources. Finally, we consider efficiency in editing model knowledge using a custom synthetic data framework, demonstrating that parameter-efficient, low-rank fine-tuning frequently outperforms full-rank fine-tuning, and, additionally, that restricting which model blocks are fine-tuned frequently improves results. Together, the results in this thesis provide new insights and techniques for combining trustworthiness and efficiency during neural network inference and training.\r\n\r\n"}],"project":[{"grant_number":"W1260-N35","name":"Vienna Graduate School on Computational Optimization","_id":"9B9290DE-BA93-11EA-9121-9846C619BF3A"}],"publisher_comment":"In reference to IEEE copyrighted material which is used with permission in this thesis, the IEEE does not endorse any of ISTA's products or services.

We show that LRD continuum spectra are well described by modified blackbodies\r\nacross ∼ 0.4 − 1.0 µm, with typical T ∼ 5000 K (λpeak ∼ 0.65 µm) across 2 dex in luminosity, and a tail toward T ∼ 2000 K.\r\nLRDs therefore trace a locus in the Hertzsprung–Russell diagram that is analogous to stars on the Hayashi track, strongly\r\nsupporting the picture that LRDs are active galactic nucleus (AGN) embedded in optically thick dense gas envelopes.\r\nHotter LRDs with λpeak < 0.65 µm typically have strong Balmer breaks, redder UV slopes, and high optical luminosities;\r\nother LRDs show weak or no Balmer breaks, and wide variety in βUV and L5100. Crucially, we demonstrate that the UV–\r\noptical continua are strongly linked to the Hα, Hβ, [O iii], and O i line properties. There is a tight linear relation between\r\nthe Hα and optical continuum luminosities, as well as Hα and O i λ8446, indicating that Balmer, O i, and optical emission\r\nmust primarily be powered by the same source. The Balmer decrement increases strongly toward higher LHα, L5100, and\r\nBalmer break strength, providing key evidence for luminosity-dependent effects of collisional (de-)excitation and resonant\r\nscattering in the gaseous envelopes. In contrast, we show that [O iii] emission likely originates from star-forming host\r\ngalaxies, with strong variation in the AGN-to-host ratio among the LRD population. Our work presents an empirical\r\ndescription of the nature and structure of LRDs, defining a new benchmark for ongoing LRD model developments.","lang":"eng"}],"volume":551,"supplementarymaterial":"yes","publication":"Monthly Notices of the Royal Astronomical Society","ddc":["520"],"arxiv":1,"DOAJ_listed":"1","type":"journal_article","date_published":"2026-09-01T00:00:00Z","fulldoi":"https://doi.org/10.1093/mnras/stag1567","das_tickbox":"1","publication_status":"published","article_processing_charge":"Yes","OA_place":"publisher","month":"09","OA_type":"gold","department":[{"_id":"JoMa"}],"external_id":{"arxiv":["2511.21820"]},"dataavailabilitystatement":"All data used in this work are publicly available through the\r\nDAWN JWST Archive (https://dawn-cph.github.io/dja/index.h\r\ntml).

Via an analysis of the duality gap we also obtain the convergence rates for the gradient of the optimal potentials and the velocity field under mild regularity assumptions.

We construct sets in even and odd dimensions, which prove that this upper bound is asymptotically tight. For example, we describe a set of N = 2(n+1) points in ℝ³ and two radii such that the first Betti number of the Čech complex at one radius is (n+1)² - 1, and the second Betti number of the Čech complex at the other radius is n².

It lays the foundation for subsequent developmental events, including gastrulation, germ layer specification, organogenesis, and the establishment of the overall body plan. Two major modes of cleavage exist in the animal kingdom: holoblastic (complete) and meroblastic (incomplete) cleavage. Because holoblastic cleavage resembles canonical cytokinesis, its biochemical and mechanical basis has been extensively studied — an annular contractile ring forms at the equator and constricts in a purse-string-like manner, leading to the complete separation of two daughter cells. In contrast, although meroblastic cleavage occurs widely across the animal kingdom (e.g. in fish, reptiles, birds, and cephalopod molluscs), its mechanical basis remains largely unclear. During meroblastic cleavage, the cytokinetic furrow forms only at one pole and does not traverse the entire embryo, raising the question of how cytokinesis proceeds in the absence of a closed contractile ring. Moreover, the resulting daughter cells are not fully separated from the underlying yolk compartment, and how these blastomeres are subsequently cellularised remains unknown. This thesis takes the zebrafish as a model organism to address both questions. The first part characterises the biochemical and mechanical mechanisms underlying non-canonical meroblastic cleavage, revealing a two-phase process in which actomyosin cable contraction and cadherin-mediated membrane adhesion act sequentially to drive furrow ingression and invagination. The second part sheds light on the spatiotemporal dynamics by which individual blastomeres become cellularised, and uncovers a previously unrecognised contribution of central blastomeres to the yolk syncytial layer."}],"day":"12","researchdata_availability":"upon request","project":[{"_id":"917c023a-16d5-11f0-9cad-eb5cafc52090","name":"Cytoplasmic self-organization into cell-like compartments as

We present grid-based hydrodynamics simulations of circumbinary accretion with an energy equation that includes viscous and hydrodynamic heating coupled to radiative blackbody cooling in the high-Mach number regime. We find that, although gas accumulates and heats at the far edge of the circumbinary cavity, the regions that launch accretion streams remain comparatively cold, leading to potentially long-lived suppression of the binary accretion rate as the large-scale feeding rate is reduced towards the Eddington limit. This runaway nonaccretion problem, however, is weakened relative to locally isothermal solutions. Despite their low accretion rates, binaries interacting with disks in a nonaccreting phase can remain sufficiently luminous and variable at optical and near-infrared frequencies to be detectable in upcoming wide-field surveys such as LSST and the Roman Space Telescope. Because of the effective truncation of the surrounding disk, though, such systems are comparatively faint in high energy, photoionizing emission, and may therefore appear as intrinsically X-ray–weak active galactic nuclei with weak or absent emission line features. We additionally suggest an update to grid-based sink prescriptions for approximating mass loss across an unresolved horizon when including an energy conservation equation.","lang":"eng"}],"supplementarymaterial":"yes","volume":1008,"file_date_updated":"2026-10-06T10:44:15Z","file":[{"date_created":"2026-10-06T10:44:15Z","file_name":"2026_AstrophysicalJour_Tiede.pdf","checksum":"f3fa2d7a10b75b74290d7a9a68a3d367","content_type":"application/pdf","date_updated":"2026-10-06T10:44:15Z","access_level":"open_access","success":1,"creator":"dernst","file_size":5621643,"relation":"main_file","file_id":"23061"}],"publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"citation":{"ista":"Tiede C, O’Neill DW, D’Orazio DJ. 2026.
