We analyse the effective radiative forcing caused by changes from Earth-like rotation to values between 1/32 and 8 times the Earth's rotation rate. The forcing differs by about 60 W m−2 between the fastest and slowest rotation cases, with a monotonically increasing positive forcing for faster-than-Earth-like rotations and a non-monotonically increasing negative forcing for slower rotations. The largest contributions to the forcing are due to changes in, in this order, the shortwave cloud radiative effect (SWCRE) and the clear-sky outgoing longwave radiation (OLR). From the fastest to the slowest rotation, the Hadley cell expands and the troposphere becomes drier, increasing the OLR. This contributes to negative forcing at slower-than-Earth-like rotations and to positive forcing at faster-than-Earth-like rotations. The SWCRE is influenced by changes in the low-level cloudiness within the Hadley cell and the baroclinic regime. With the expansion of the Hadley cell, the area of enhanced tropospheric stability increases, resulting in more low-level clouds, a higher SWCRE, and increased negative forcing. The non-monotonicity results from an intermediate decrease in the SWCRE caused by the disappearance of baroclinic eddies as the Hadley cell reaches global extension. At rotations faster than Earth-like, the decrease in the SWCRE, mainly due to the weakening of baroclinic eddies and storm systems, leads to an increase in positive forcing. In summary, changes in the SWCRE, driven by different circulation responses at slower-than-Earth-like and faster-than-Earth-like rotations, strongly influence the TOA radiant energy budget. These effects, along with a substantial contribution from the clear-sky OLR, could impact the habitability of Earth-like rotating planets."}],"publication":"Weather and Climate Dynamics","file":[{"file_id":"19680","creator":"dernst","date_updated":"2025-05-12T08:23:10Z","success":1,"file_name":"2025_WeatherClimateDynam_Gnanaraj.pdf","checksum":"2ea68f7e51ee39ccb6886719a83a78ca","date_created":"2025-05-12T08:23:10Z","file_size":6500575,"access_level":"open_access","relation":"main_file","content_type":"application/pdf"}],"publication_status":"published","article_type":"original","publisher":"Copernicus Publications","date_created":"2025-05-11T22:02:38Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"quality_controlled":"1","date_updated":"2025-09-30T12:26:21Z","language":[{"iso":"eng"}],"date_published":"2025-04-25T00:00:00Z","_id":"19663","has_accepted_license":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"month":"04","ddc":["570"],"year":"2025","status":"public","volume":11,"title":"Protecting centrosomes from fracturing enables efficient cell navigation","oa_version":"Published Version","publication_identifier":{"eissn":["2375-2548"]},"pmid":1,"publication_status":"published","publication":"Science Advances","file":[{"creator":"dernst","file_id":"19679","date_updated":"2025-05-12T07:46:10Z","checksum":"e8ba22922fa5b23ccfcce8865f57226c","file_name":"2025_ScienceAdvance_Schmitt.pdf","success":1,"file_size":2707050,"date_created":"2025-05-12T07:46:10Z","content_type":"application/pdf","relation":"main_file","access_level":"open_access"}],"abstract":[{"text":"The centrosome is a microtubule orchestrator, nucleating and anchoring microtubules that grow radially and exert forces on cargos. At the same time, mechanical stresses from the microenvironment and cellular shape changes compress and bend microtubules. Yet, centrosomes are membraneless organelles, raising the question of how centrosomes withstand mechanical forces. Here, we discover that centrosomes can deform and even fracture. We reveal that centrosomes experience deformations during navigational pathfinding within motile cells. Coherence of the centrosome is maintained by Dyrk3 and cNAP1, preventing fracturing by forces. While cells can compensate for the depletion of centriolar-based centrosomes, the fracturing of centrosomes impedes cellular function by generating coexisting microtubule organizing centers that compete during path navigation and thereby cause cellular entanglement in the microenvironment. Our findings show that cells actively maintain the integrity of the centrosome to withstand mechanical forces. These results suggest that centrosome stability preservation is fundamental, given that almost all cells in multicellular organisms experience forces.","lang":"eng"}],"doi":"10.1126/sciadv.adx4047","DOAJ_listed":"1","date_created":"2025-05-11T22:02:38Z","publisher":"AAAS","article_type":"original","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"ieee":"M.

QMBSs are non-thermal highly excited eigenstates that coexist with typical eigenstates in the spectrum of many-body Hamiltonians, and have since been reported in multiple theoretical models, including the so-called PXP model, approximately realized by Rydberg simulators. At the same time, questions of how common QMBSs are and in what models they are physically realized remain open. In this Letter, we demonstrate that QMBSs exist in a broader family of models that includes and generalizes PXP to longer-range constraints and states with different periodicity. We show that in each model, multiple QMBS families can be found. Each of them relies on a different approximate algebra, leading to oscillatory dynamics in all cases. However, in contrast to the PXP model, their observation requires launching dynamics from weakly entangled initial states rather than from a product state. QMBSs reported here may be experimentally probed using Rydberg atom simulator in the regime of longer-range Rydberg blockades."}],"file":[{"relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_size":1028993,"date_created":"2025-05-12T07:33:38Z","date_updated":"2025-05-12T07:33:38Z","creator":"dernst","file_id":"19677","checksum":"b7f581291e20f152d0efc64727314ca2","file_name":"2025_PhysReviewLetters_Kerschbaumer.pdf","success":1}],"publication":"Physical Review Letters","doi":"10.1103/PhysRevLett.134.160401","date_created":"2025-05-11T22:02:38Z","article_type":"original","publisher":"American Physical Society","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","citation":{"ieee":"A.

Most existing bias prevention measures provide probabilistic fairness guarantees in the long run, and it is possible that the decisions are biased on any decision sequence of fixed length. We introduce *fairness shielding*, where a symbolic decision-maker---the fairness shield---continuously monitors the sequence of decisions of another deployed black-box decision-maker, and makes interventions so that a given fairness criterion is met while the total intervention costs are minimized. We present four different algorithms for computing fairness shields, among which one guarantees fairness over fixed horizons, and three guarantee fairness periodically after fixed intervals. Given a distribution over future decisions and their intervention costs, our algorithms solve different instances of bounded-horizon optimal control problems with different levels of computational costs and optimality guarantees. Our empirical evaluation demonstrates the effectiveness of these shields in ensuring fairness while maintaining cost efficiency across various scenarios."}],"publication_status":"published","oa_version":"Preprint","publication_identifier":{"issn":["2159-5399"],"eissn":["2374-3468"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Association for the Advancement of Artificial Intelligence","date_created":"2025-05-11T22:02:39Z","day":"11","OA_place":"repository","intvolume":"        39","article_processing_charge":"No","type":"conference","oa":1,"citation":{"ieee":"F.

In *robust* MDP (RMDP), every action is associated with an *uncertainty set* of probability distributions, modelling that transition probabilities are not known precisely. Based on the known theoretical connection to stochastic games, we provide a framework for solving RMDPs that is generic, reliable, and efficient. It is *generic* both with respect to the model, allowing for a wide range of uncertainty sets, including but not limited to intervals, L1- or L2-balls, and polytopes; and with respect to the objective, including long-run average reward, undiscounted total reward, and stochastic shortest path. It is *reliable*, as our approach not only converges in the limit, but provides precision guarantees at any time during the computation. It is *efficient* because -- in contrast to state-of-the-art approaches -- it avoids explicitly constructing the underlying stochastic game. Consequently, our prototype implementation outperforms existing tools by several orders of magnitude and can solve RMDPs with a million states in under a minute."}],"publication":"Proceedings of the 39th AAAI Conference on Artificial Intelligence","doi":"10.1609/aaai.v39i25.34865","publication_identifier":{"eissn":["2374-3468"],"issn":["2159-5399"]},"oa_version":"Preprint"},{"oa_version":"Preprint","publication_identifier":{"issn":["2159-5399"],"eissn":["2374-3468"]},"publication_status":"published","abstract":[{"lang":"eng","text":"The problem of checking satisfiability of linear real arithmetic (LRA) and non-linear real arithmetic (NRA) formulas has broad applications, in particular, they are at the heart of logic-related applications such as logic for artificial intelligence, program analysis, etc. While there has been much work on checking satisfiability of unquantified LRA and NRA formulas, the problem of checking satisfiability of quantified LRA and NRA formulas remains a significant challenge. The main bottleneck in the existing methods is a computationally expensive quantifier elimination step. In this work, we propose a novel method for efficient quantifier elimination in quantified LRA and NRA formulas. We propose a template-based Skolemization approach, where we automatically synthesize linear/polynomial Skolem functions in order to eliminate quantifiers in the formula. The key technical ingredient in our approach are Positivstellensätze theorems from algebraic geometry, which allow for an efficient manipulation of polynomial inequalities. Our method offers a range of appealing theoretical properties combined with a strong practical performance. On the theory side, our method is sound, semi-complete, and runs in subexponential time and polynomial space, as opposed to existing sound and complete quantifier elimination methods that run in doubly-exponential time and at least exponential space. On the practical side, our experiments show superior performance compared to state of the art SMT solvers in terms of the number of solved instances and runtime, both on LRA and on NRA benchmarks."}],"publication":"Proceedings of the 39th AAAI Conference on Artificial Intelligence","doi":"10.1609/aaai.v39i11.33213","date_created":"2025-05-11T22:02:39Z","publisher":"Association for the Advancement of Artificial Intelligence","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Chatterjee, K., Goharshady, E., Karrabi, M., Motwani, H.

To ensure the satisfaction of a safety property, learning-based methods jointly learn a control policy together with a certificate function for the property. Popular examples include barrier functions for safety and Lyapunov functions for asymptotic stability. While there has been significant progress on learning-based control with certificate functions in the white-box setting, where the correctness of the certificate function can be formally verified, there has been little work on ensuring their reliability in the black-box setting where the system dynamics are unknown. In this work, we consider the problems of certifying and repairing neural network control policies and certificate functions in the black-box setting. We propose a novel framework that utilizes runtime monitoring to detect system behaviors that violate the property of interest under some initially trained neural network policy and certificate. These violating behaviors are used to extract new training data, that is used to re-train the neural network policy and the certificate function and to ultimately repair them. We demonstrate the effectiveness of our approach empirically by using it to repair and to boost the safety rate of neural network policies learned by a state-of-the-art method for learning-based control on two autonomous system control tasks.","lang":"eng"}],"publication":"Proceedings of the 39th AAAI Conference on Artificial Intelligence","publisher":"Association for the Advancement of Artificial Intelligence","date_created":"2025-05-11T22:02:40Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"type":"conference","article_processing_charge":"No","citation":{"short":"E.

Several seminal results in the literature focus on special cases. For example, turn-based stochastic games correspond to conditions C2 and C3; and Markov decision process to conditions C2, C3, and C4. However, the systematic computational complexity study of all the cases has not been explored, which we address in this work. Some highlights of our results are: with conditions C2 and C4, and with conditions C3 and C4, the problem is NP-complete, whereas with condition C1 only, the problem is in UP intersects coUP.

Despite its simple ingredient list, achieving the perfect texture and creaminess of the sauce can be challenging. In this study, we systematically explore the phase behavior of Cacio e pepe sauce, focusing on its stability at increasing temperatures for various proportions of cheese, water, and starch. We identify starch concentration as the key factor influencing sauce stability, with direct implications for practical cooking. Specifically, we delineate a regime where starch concentrations below 1% (relative to cheese mass) lead to the formation of system-wide clumps, a condition determining what we term the “Mozzarella Phase” and corresponding to an unpleasant and separated sauce. Additionally, we examine the impact of cheese concentration relative to water at a fixed starch level, observing a lower critical solution temperature that we theoretically rationalized by means of a minimal effective free-energy model. We further analyze the effect of a less traditional stabilizer, trisodium citrate, and observe a sharp transition from the Mozzarella Phase to a completely smooth and stable sauce, in contrast to starch-stabilized mixtures, where the transition is more gradual. Finally, we present a scientifically optimized recipe based on our findings, enabling a consistently flawless execution of this classic dish."}],"publication_status":"published","article_type":"original","publisher":"AIP Publishing","date_created":"2025-05-11T22:02:40Z","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","type":"journal_article","article_processing_charge":"Yes (in subscription journal)","oa":1,"citation":{"short":"G.

Prior studies in South American temperate forests have mainly focused on initial stages, lacking a comprehensive understanding of the entire life cycle within productive systems. We assessed the population dynamics of two key species of mixed forests in northern Patagonia (Austrocedrus chilensis and Nothofagus dombeyi) under two silvopastoral use intensities (high vs. low), using demographic techniques and population projection models. Over 3 years, we quantified vital rates (survival, fertility, growth, reversion and stasis) and used matrix models to calculate deterministic population growth rates (λ). High-intensity silvopastoral use had predominantly negative effects on the elements of the projection matrices of A. chilensis, whereas N. dombeyi exhibited mostly positive or no changes. As a result, projections indicated slight population decreases for A. chilensis (mostly λ < 1) at high silvopastoral use levels compared to low levels, while N. dombeyi showed similar projections (λ ≅ 1) between use levels. Decreased λ for A. chilensis resulted mainly from lower adult tree survival, while early life stages had limited influence on λ for these long-lived species. In summary, silvopastoral use affects population dynamics of key tree species of these mixed forests of northern Patagonia, with implications for sustainable management. Our findings highlight the importance of considering the entire life cycle and suggest targeted practices to enhance A. chilensis populations.","lang":"eng"}],"publication":"Austral Ecology","doi":"10.1111/aec.70058","date_created":"2025-05-11T22:02:41Z","publisher":"Wiley","article_type":"original","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","status":"public","volume":50,"title":"A life-cycle approach to understand consequences of silvopastoral use on two native tree species of Northern Patagonia","quality_controlled":"1","language":[{"iso":"eng"}],"date_updated":"2025-09-30T12:31:04Z","date_published":"2025-04-01T00:00:00Z","_id":"19671","month":"04","year":"2025"},{"status":"public","corr_author":"1","title":"Intensity oscillations of tropical cyclones: Surface versus mid and upper tropospheric processes","volume":17,"_id":"19672","date_published":"2025-04-01T00:00:00Z","date_updated":"2025-09-30T12:30:29Z","language":[{"iso":"eng"}],"quality_controlled":"1","year":"2025","ddc":["550"],"month":"04","has_accepted_license":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"day":"01","file_date_updated":"2025-05-12T12:17:08Z","OA_place":"publisher","intvolume":"        17","type":"journal_article","article_processing_charge":"Yes","oa":1,"citation":{"ieee":"A.

Simulations performed using the non-hydrostatic, high-resolution model System for Atmosphere Modeling in idealized settings (rotating radiative-convective equilibrium on a doubly periodic domain) show early intensification consistent with these theoretical expectations, but different intensity evolution, with the cyclone undergoing an oscillation in wind speed. This oscillation can be linked to feedbacks between the cyclone intensity and air buoyancy: convective heating, radiative heating, and mixing with warm low stratospheric air warm the mid and upper troposphere of the cyclone stabilizing the air column and thus reducing its intensity. After the intensity decay phase, mid and upper tropospheric cooling, mostly through cold advection from the surroundings, cooled by radiation, rebuilds Convective Available Potential Energy, that peaks just before a new intensification phase. These idealized simulations thus highlight the potentially important interactions between a tropical cyclone, its environment and radiation.","lang":"eng"}],"publication_status":"published","oa_version":"Published Version","publication_identifier":{"eissn":["1942-2466"]},"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publisher":"Wiley","article_type":"original","date_created":"2025-05-11T22:02:41Z"},{"status":"public","arxiv":1,"corr_author":"1","page":"1-26","title":"Prime Hasse principles via diophantine second moments","volume":3,"_id":"19673","date_published":"2025-01-23T00:00:00Z","date_updated":"2025-05-12T10:26:00Z","language":[{"iso":"eng"}],"quality_controlled":"1","ddc":["510"],"year":"2025","month":"01","tmp":{"name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","short":"CC BY-NC (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png"},"has_accepted_license":"1","day":"23","OA_place":"publisher","file_date_updated":"2025-05-12T10:23:26Z","intvolume":"         3","type":"journal_article","article_processing_charge":"No","oa":1,"citation":{"short":"V.

In this paper, we analyze this phenomenon in vision transformers, focusing on the spectral geometry of residuals, and explore its implications for modality alignment in vision-language models. First, we link it to the intrinsically low-dimensional structure of visual head representations, zooming into their principal components and showing that they encode specialized roles across a wide variety of input data distributions. Then, we analyze the effect of head specialization in multimodal models, focusing on how improved alignment between text and specialized heads impacts zero-shot classification performance. This specialization-performance link consistently holds across diverse pre-training data, network sizes, and objectives, demonstrating a powerful new mechanism for boosting zero-shot classification through targeted alignment. Ultimately, we translate these insights into actionable terms by introducing ResiDual, a technique for spectral alignment of the residual stream. Much like panning for gold, it lets the noise from irrelevant unit principal components (i.e., attributes) wash away to amplify task-relevant ones. Remarkably, this dual perspective on modality alignment yields fine-tuning level performance on different data distributions while modelling an extremely interpretable and parameter-efficient transformation, as we extensively show on 70 pre-trained network-dataset combinations (7 models, 10 datasets)."}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2411.00246"}],"doi":"10.48550/arXiv.2411.00246","oa_version":"Preprint","date_updated":"2025-05-19T07:03:16Z","language":[{"iso":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2025","date_created":"2025-05-11T22:02:41Z","month":"04"},{"citation":{"ieee":"G.

In a five-paper series, we adopt a variety of perspectives and techniques to relate the properties of systems of increasing complexity to their underlying coherent structures. \r\n\r\nInitially, we take a dynamical systems point of view, seeing turbulent flow as a chaotic trajectory bouncing between exact unstable solutions of the underlying equations of motion. Using persistent homology, the main tool of topological data analysis capturing the persistence across scales of topological features in a point cloud, we introduce a method that quantifies visits of turbulent trajectories to unstable time-periodic solutions, also called periodic orbits. We demonstrate this method first in the Rössler and Kuramoto–Sivashinsky systems. Using this method in 3D Kolmogorov flow, we extract a Markov chain from turbulent data, where each node corresponds to the neighbourhood of a periodic orbit. The invariant distribution of this Markov chain reproduces expectation values on turbulent data when it is used to weight averages on the respective periodic orbits.\r\n\r\nIn more realistic, wall-bounded settings, such as plane-Couette flow (pcf) driven by the relative motion of the walls, or plane-Poiseuille flow (ppf) driven by a pressure gradient, finding exact solutions is difficult. We use dynamic mode decomposition (DMD), a dimensionality reduction method for sequential data, to identify and approximate low-dimensional dynamics without knowing any exact solutions. Most spatially-extended systems are equivariant under translations, and in such cases spatial drifts dominate DMD, hindering its use in the search for and modelling of low-dimensional dynamics. We augment DMD with a symmetry reduction method trained on turbulent data to stop it from seeing translations as a feature, improving its ability to extract dynamical information in translation-equivariant systems. We find segments of turbulent trajectories that linearize well with their symmetry-reduced DMD spectra, akin to dynamics near exact solutions. Searching for harmonics in the spectra gives leads for periodic orbits with spatial drifts, one of which converges to a new solution.\r\n\r\nIn larger domains, turbulence can localize and coexist with surrounding laminar flow. Our preceding approaches are global, taking all of a domain into account at once, and cannot readily treat each localized patch individually. Working first in a minimal oblique domain that can host a single 1D-localized turbulent patch, we find that turbulence in ppf is connected to a stable periodic orbit at a flow velocity much lower than when turbulence is first onset. We show that, well in advance of sustained turbulence, chaos sets in explosively, and for long time horizons, time series are consistent with that of a random process.\r\n\r\nFinally, in much larger domains, we study and compare 2D-localized turbulence that appears as large-scale inclined structures, called stripes, in ppf and pcf. While appearing similar, we find that stripes in these two settings differ significantly in terms of how they sustain themselves, and in higher velocities, how they proliferate.","lang":"eng"}],"publication_status":"published","degree_awarded":"PhD","doi":"10.15479/AT-ISTA-19684","date_created":"2025-05-12T15:12:28Z","publisher":"Institute of Science and Technology Austria","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","corr_author":"1","page":"155","supervisor":[{"id":"3A374330-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-2057-2754","first_name":"Björn","full_name":"Hof, Björn","last_name":"Hof"}],"acknowledged_ssus":[{"_id":"ScienComp"}],"status":"public","title":"Transition to turbulence : Data-, solution-, and pattern-driven approaches","language":[{"iso":"eng"}],"date_updated":"2026-06-18T19:23:35Z","_id":"19684","date_published":"2025-05-13T00:00:00Z","alternative_title":["ISTA Thesis"],"month":"05","has_accepted_license":"1","related_material":{"record":[{"id":"9558","relation":"part_of_dissertation","status":"public"},{"status":"public","relation":"part_of_dissertation","id":"12105"},{"status":"public","relation":"part_of_dissertation","id":"13274"},{"status":"public","id":"14466","relation":"part_of_dissertation"},{"id":"7563","relation":"part_of_dissertation","status":"public"}]},"ddc":["514","519","532","004"],"year":"2025"},{"date_created":"2025-05-14T10:46:07Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","short":"CC BY-NC-SA (4.0)","image":"/images/cc_by_nc_sa.png"},"has_accepted_license":"1","month":"07","related_material":{"record":[{"relation":"research_data","id":"20321","status":"public"}],"link":[{"url":"http.//doi.org/10.1021/jacs.5c09057","description":"Paper to which the dataset corresponds.","relation":"research_paper"}]},"publisher":"Institute of Science and Technology Austria","contributor":[{"first_name":"Paul","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","orcid":"0000-0002-9350-7606","last_name":"Schanda","contributor_type":"project_leader"},{"first_name":"Vidhyalakshmi","contributor_type":"researcher","last_name":"Sridharan"},{"first_name":"Motilal","contributor_type":"researcher","last_name":"Uttarkabat"},{"first_name":"Christopher","last_name":"Jaroniec","contributor_type":"researcher"},{"first_name":"Matthias","contributor_type":"researcher","last_name":"Ernst"},{"id":"c316e53f-b965-11eb-b128-bb26acc59c00","orcid":"0000-0001-8729-7326","first_name":"Petra","contributor_type":"researcher","last_name":"Rovo"}],"user_id":"68b8ca59-c5b3-11ee-8790-cd641c68093d","year":"2025","oa_version":"Published Version","date_updated":"2026-06-10T08:33:41Z","date_published":"2025-07-31T00:00:00Z","_id":"19696","file":[{"access_level":"open_access","relation":"main_file","content_type":"application/zip","date_created":"2025-07-31T08:14:40Z","file_size":557878455,"date_updated":"2025-07-31T08:14:40Z","file_id":"20094","creator":"btatman","success":1,"file_name":"dataset.zip","checksum":"4c2d29404e070bda7d5619f728ec555c"},{"file_size":3514,"date_created":"2025-07-31T08:14:21Z","content_type":"text/plain","relation":"main_file","access_level":"open_access","creator":"btatman","file_id":"20095","date_updated":"2025-07-31T08:14:21Z","checksum":"6cbccd602be0ecb6ddb1f81fdfcadf92","file_name":"readme.txt","success":1}],"doi":"10.15479/AT-ISTA-19696","author":[{"last_name":"Tatman","full_name":"Tatman, Benjamin","id":"71cda2f3-e604-11ee-a1df-da10587eda3f","first_name":"Benjamin"}],"title":"Dataset for \"Bumps on the Road: The Way to Clean Relaxation Dispersion in the Solid State\"","department":[{"_id":"PaSc"}],"citation":{"chicago":"Tatman, Benjamin. “Dataset for ‘Bumps on the Road: The Way to Clean Relaxation Dispersion in the Solid State.’” Institute of Science and Technology Austria, 2025. <a href=\"https://doi.org/10.15479/AT-ISTA-19696\">https://doi.org/10.15479/AT-ISTA-19696</a>.","short":"B.

We present new grid-based hydrodynamics simulations, performed with the binary on the grid and a locally isothermal equation of state, in which the binary is seen to functionally \"stop accreting\" if the orbital Mach number in the disk exceeds a threshold value of about 40. Above this threshold, the disk continues to extract angular momentum from the binary orbit, but it delivers very little mass to the black holes and instead piles up mass in a ring surrounding the binary. This ring will eventually become viscously relaxed and deliver mass to the binary at the large-scale inflow rate. However, we show that the timescale for such relaxation can far exceed the implied binary lifetime. We demonstrate that the ability of a binary–disk system to equilibrate is dependent on the efficiency at which accretion streams deposit mass onto the binary, which, in turn is highly sensitive to the thermodynamic conditions of the inner disk. If disks around massive black hole binaries do operate in such nonaccreting regimes, it suggests these systems may be dimmer than their single black hole counterparts but could exhibit dramatic rebrightening after the black holes inspiral and merge. This dimming begins in the UV/optical and could completely choke high-energy emission, such that these systems would likely be intrinsically X-ray weak with reddened continua, potentially resembling the spectra of \"little red dots\" recently identified in JWST observations.","lang":"eng"}],"publication":"The Astrophysical Journal","publication_status":"published","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"oa_version":"Published Version"},{"department":[{"_id":"JoMa"}],"acknowledgement":"B.W. and J.L. acknowledge support from JWST-GO-04233.009-A.

Here, we report an unusually bright LRD (zspec = 3.1) observed as part of the RUBIES program. This LRD exhibits broad emission lines (FWHM ∼ 4000 km s−1), a blue UV continuum, a clear Balmer break, and a red continuum sampled out to rest-frame 4 μm with MIRI. We develop a new joint galaxy and active galactic nucleus (AGN) model within the Prospector Bayesian inference framework and perform spectrophotometric modeling using NIRCam, MIRI, and NIRSpec/Prism observations. Our fiducial model reveals a M* ∼ 109 M⊙ galaxy alongside a dust-reddened AGN driving the optical emission. Explaining the rest-frame optical color as a reddened AGN requires AV ≳ 3, suggesting that a great majority of the accretion disk energy is reradiated as dust emission. Yet, despite clear AGN signatures, we find a surprising lack of hot torus emission, which implies that either the dust emission in this object must be cold, or the red continuum must instead be driven by a massive, evolved stellar population of the host galaxy—seemingly inconsistent with the high-EW broad lines (Hα rest-frame EW ∼ 800 Å). The widths and luminosities of Pa-β, Pa-δ, Pa-γ, and Hα imply a modest black hole mass of MBH ∼ 108 M⊙. Additionally, we identify a narrow blueshifted He i λ 1.083 μm absorption feature in NIRSpec/G395M spectra, signaling an ionized outflow with kinetic energy up to ∼1% the luminosity of the AGN. The low redshift of RUBIES-BLAGN-1, combined with the depth and richness of the JWST imaging and spectroscopic observations, provides a unique opportunity to build a physical model for these so-far mysterious LRDs, which may prove to be a crucial phase in the early formation of massive galaxies and their supermassive black holes.","lang":"eng"}],"file":[{"access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2025-05-19T07:08:39Z","file_size":3522072,"file_name":"2025_AstrophysicalJour_Wang.pdf","success":1,"checksum":"1a9ff4516d11808bc6947744473c9fc2","date_updated":"2025-05-19T07:08:39Z","file_id":"19707","creator":"dernst"}],"publication":"The Astrophysical Journal","doi":"10.3847/1538-4357/adc1ca","DOAJ_listed":"1","publication_identifier":{"eissn":["1538-4357"],"issn":["0004-637X"]},"oa_version":"Published Version","volume":984,"title":"RUBIES: JWST/NIRSpec confirmation of an infrared-luminous, broad-line Little Red Dot with an ionized outflow","status":"public","arxiv":1,"year":"2025","ddc":["520"],"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"has_accepted_license":"1","month":"05","date_published":"2025-05-09T00:00:00Z","_id":"19700","quality_controlled":"1","language":[{"iso":"eng"}],"date_updated":"2026-02-16T12:42:43Z"},{"date_published":"2025-05-01T00:00:00Z","_id":"19701","date_updated":"2025-09-30T12:33:33Z","language":[{"iso":"eng"}],"quality_controlled":"1","ddc":["570"],"year":"2025","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"has_accepted_license":"1","month":"05","status":"public","page":"249-274","corr_author":"1","title":"Information processing in biochemical networks","volume":54,"doi":"10.1146/annurev-biophys-060524-102720","publication_status":"published","abstract":[{"lang":"eng","text":"Living systems are characterized by controlled flows of matter, energy, and information. While the biophysics community has productively engaged with the first two, addressing information flows has been more challenging, with some scattered success in evolutionary theory and a more coherent track record in neuroscience. Nevertheless, interdisciplinary work of the past two decades at the interface of biophysics, quantitative biology, and engineering has led to an emerging mathematical language for describing information flows at the molecular scale. This is where the central processes of life unfold: from detection and transduction of environmental signals to the readout or copying of genetic information and the triggering of adaptive cellular responses. Such processes are coordinated by complex biochemical reaction networks that operate at room temperature, are out of equilibrium, and use low copy numbers of diverse molecular species with limited interaction specificity. Here we review how flows of information through biochemical networks can be formalized using information-theoretic quantities, quantified from data, and computed within various modeling frameworks. Optimization of information flows is presented as a candidate design principle that navigates the relevant time, energy, crosstalk, and metabolic constraints to predict reliable cellular signaling and gene regulation architectures built of individually noisy components."}],"publication":"Annual review of biophysics","file":[{"file_size":317925,"date_created":"2025-05-19T07:55:51Z","relation":"main_file","content_type":"application/pdf","access_level":"open_access","creator":"dernst","file_id":"19710","date_updated":"2025-05-19T07:55:51Z","checksum":"9ab623b2bc45dcd5fdd2c9577ea8ae9f","success":1,"file_name":"2025_AnnualReviewBiophysics_Tkacik.pdf"}],"pmid":1,"publication_identifier":{"eissn":["1936-1238"]},"oa_version":"Published Version","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publisher":"Annual Reviews","article_type":"original","date_created":"2025-05-18T22:02:50Z","file_date_updated":"2025-05-19T07:55:51Z","OA_place":"publisher","day":"01","intvolume":"        54","oa":1,"article_processing_charge":"Yes (in subscription journal)","type":"journal_article","citation":{"chicago":"Tkačik, Gašper, and Pieter Rein Ten Wolde. “Information Processing in Biochemical Networks.” <i>Annual Review of Biophysics</i>.

A newly occurring mutation that invades a population of residents can either fixate on the whole population or it can go extinct due to random drift. The duration of the process depends not only on the total population size n, but also on the spatial structure of the population. In this work, we consider the Moran process with a single type of individuals who invade and colonize an otherwise empty environment. Mathematically, this corresponds to the setting where the residents have zero reproduction rate, thus they never reproduce. The spatial structure is represented by a graph. We present two main contributions. First, in contrast to the Moran process in which residents do reproduce, we show that the colonization time is always at most a polynomial function of the population size n. Namely, we show that colonization always takes at most 1/2n^3 - 1/2n^2 expected steps, and for each n, we identify the slowest graph where it takes exactly that many steps. Moreover, we establish a stronger bound of roughly n^2.5 steps for undirected graphs and an even stronger bound of roughly n^2 steps for so-called regular graphs. Second, we discuss various complications that one faces when attempting to measure fixation times and colonization times in spatially structured populations, and we propose to measure the real duration of the process, rather than counting the steps of the classic Moran process."}],"file":[{"checksum":"73e35151eebd5064972c5a07ffdf2b69","file_name":"2025_PloSCompBio_Kopfova.pdf","success":1,"date_updated":"2025-05-19T07:45:31Z","creator":"dernst","file_id":"19709","relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_size":6805943,"date_created":"2025-05-19T07:45:31Z"}],"publication":"PLoS computational biology","publication_status":"published","oa_version":"Published Version","publication_identifier":{"eissn":["1553-7358"]},"title":"Colonization times in Moran process on graphs","volume":21,"status":"public","arxiv":1,"page":"e1012868","ddc":["000"],"year":"2025","month":"05","has_accepted_license":"1","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"_id":"19702","date_published":"2025-05-01T00:00:00Z","language":[{"iso":"eng"}],"date_updated":"2025-09-30T12:34:03Z","quality_controlled":"1"}]
