It had been clearly demonstrated and well-accepted that the intracellular auxin receptors, TIR1/AFBs, are F-box proteins mediating transcriptional auxin signaling by their E3 ubiquitin ligase activity, which targets and sends for degradation the Aux/IAA transcriptional repressors. The recent discovery of adenylate cyclase (AC) and guanylate cyclase (GC) activities for TIR1/AFBs open entirely new perspectives on how auxin signaling can operate. This chapter traces back the history of how canonical transcriptional auxin signaling was established and introduces the discovery of the TIR1/AFBs-mediated nontranscriptional signaling branch. Finally, the current understanding and open questions of how TIR1/AFBs’ AC and GC activities contribute to the transcriptional and nontranscriptional auxin signaling are discussed, highlighting the possibility that cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) act as second messengers in auxin signal transduction. alternative_title: - Foundations and Frontiers in Enzymology article_processing_charge: No author: - first_name: Linlin full_name: Qi, Linlin last_name: Qi - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: 'Qi L, Friml J.

Collagen IV molecules assemble into networks, providing stiffness and elasticity to tissues and informing cell and organ shape, especially during development. In this work, we develop two coarse-grained models for collagen IV molecules that retain biochemical bond specificity and coarse grain at different length scales. Through molecular-dynamics simulations, we test the assembly and mechanics of the resulting networks and measure their response to strain in terms of stress, microscopic alignment, and bond dynamics. Within the basement membrane, collagen IV networks rearrange by molecule turnover, which affects tissue organization and can be linked with enzyme activity. Here we explore network rearrangements via bond remodeling, the process of breaking and remaking of bonds between network molecules. We then investigate the effects of active (enzymatic) bond remodeling. We find that this nonequilibrium remodeling allows a network to keep its integrity under strain, while relaxing fully over a variety of timescales, a dynamic response that is unavailable to networks undergoing equilibrium remodeling. acknowledgement: This work received funding from the European Research Council under the European Union's Horizon 2020 research and innovation program through Grant Agreement No. 802960 (B.M., V.S., I.P., and A.Š.), the European Union's Horizon 2020 research and innovation program under the Marie Skłodowska-Curie Grant Agreement No. 101034413 (I.P.), the NOMIS Foundation (F.P.-V.), the National Centre for the Replacement, Refinement and Reduction of Animals in Research Grant No. NC/T002425/1 (N.K.), Leverhulme Trust project Grant No. RPG-2020-068 (N.K.), MRC Fellowship No. MR/W027437/1 (Y.M.), a Lister Institute Research Prize (Y.M.) and EMBO Young Investigator Programme (Y.M. and A.Š.). article_number: '033019' article_processing_charge: Yes article_type: original author: - first_name: Billie full_name: Meadowcroft, Billie id: a4725fd6-932b-11ed-81e2-c098c7f37ae1 last_name: Meadowcroft orcid: 0000-0003-3441-1337 - first_name: Valerio full_name: Sorichetti, Valerio id: ef8a92cb-c7b6-11ec-8bea-e1fd5847bc5b last_name: Sorichetti orcid: 0000-0002-9645-6576 - first_name: Eryk full_name: Ratajczyk, Eryk last_name: Ratajczyk - first_name: Fernanda L full_name: Perez Verdugo, Fernanda L id: 4ecec223-9070-11ef-a0a9-bc76077bea8d last_name: Perez Verdugo - first_name: Nargess full_name: Khalilgharibi, Nargess last_name: Khalilgharibi - first_name: Yanlan full_name: Mao, Yanlan last_name: Mao - first_name: Ivan full_name: Palaia, Ivan id: 9c805cd2-4b75-11ec-a374-db6dd0ed57fa last_name: Palaia orcid: ' 0000-0002-8843-9485 ' - first_name: Anđela full_name: Šarić, Anđela id: bf63d406-f056-11eb-b41d-f263a6566d8b last_name: Šarić orcid: 0000-0002-7854-2139 citation: ama: Meadowcroft B, Sorichetti V, Ratajczyk E, et al.

Our work is motivated by experiments showing that standard loss-based fine-tuning methods are not able to achieve high accuracy in this setting, especially at high sparsity targets. To address this issue, we perform a detailed study of knowledge distillation losses for fine-tuning of sparse models. We determine an L2-based distillation approach that we term ‘SquareHead’, which enables accurate recovery even at higher sparsities. Investigating the question of efficient inference, we show that sparse LLMs can be executed faster by taking advantage of sparsity. Specifically, we exhibit end-to-end results showing speedups enabled by sparsity, while recovering accuracy, on the following models and tasks, respectively: T5 for language translation, Whisper for speech translation, and open GPT-type models such as the Mosaic Pre-Trained Transformer (MPT) and Llama-2 models for text generation. In particular, for popular generative tasks, we show for the first time that sparse fine-tuning can reach 75% sparsity without drops in accuracy, and provide notable end-to-end speedups for inference on CPUs. Moreover, we also highlight that sparsity is compatible with other compression approaches, such as quantization.' acknowledgement: We would like to thank Eugenia Iofinova for useful comments on an earlier version of this draft, and Artur Niederfahrenhorst for useful suggestions regarding fine-tuning on the GSM8k dataset. alternative_title: - 'Machine Translation: Technologies and Applications' article_processing_charge: No arxiv: 1 author: - first_name: Eldar full_name: Kurtic, Eldar id: 47beb3a5-07b5-11eb-9b87-b108ec578218 last_name: Kurtic - first_name: Denis full_name: Kuznedelev, Denis last_name: Kuznedelev - first_name: Elias full_name: Frantar, Elias id: 09a8f98d-ec99-11ea-ae11-c063a7b7fe5f last_name: Frantar - first_name: Michael full_name: Goinv, Michael last_name: Goinv - first_name: Shubhra full_name: Pandit, Shubhra last_name: Pandit - first_name: Abhinav full_name: Agarwalla, Abhinav last_name: Agarwalla - first_name: Tuan full_name: Nguyen, Tuan last_name: Nguyen - first_name: Alexandre full_name: Marques, Alexandre last_name: Marques - first_name: Mark full_name: Kurtz, Mark last_name: Kurtz - first_name: Dan-Adrian full_name: Alistarh, Dan-Adrian id: 4A899BFC-F248-11E8-B48F-1D18A9856A87 last_name: Alistarh orcid: 0000-0003-3650-940X citation: ama: 'Kurtic E, Kuznedelev D, Frantar E, et al.

It allows a large group of N users to maintain a shared secret key that is frequently rotated by the\r\ngroup members in order to achieve forward secrecy and post compromise security. The group messaging scheme Messaging Layer Security (MLS) standardized by the IETF makes use of a CGKA called TreeKEM which arranges the N group members in a binary tree. Here, each node is associated with a public-key, each user is assigned one of the leaves, and a user knows the corresponding secret keys from their leaf to the root. To update the key material known to them, a user must just replace keys at log(N) nodes, which requires them to create and upload log(N) ciphertexts. Such updates must be processed sequentially by all users, which for large groups is impractical. To allow for concurrent updates, TreeKEM uses the “propose and commit” paradigm, where multiple users can concurrently propose to update (by just sampling a fresh leaf key), and a single user can then commit to all proposals at once. Unfortunately, this process destroys the binary tree structure as the tree gets pruned and some nodes must be “blanked” at the cost of increasing the in-degree of others, which makes the commit operation, as well as, future commits more costly. In the worst case, the update cost (in terms of uploaded ciphertexts) per user can grow from log(N) to Ω(N). In this work we provide two main contributions. First, we show that MLS’ communication complexity is bad not only in the worst case but also if the proposers and committers are chosen at random: even if there’s just one update proposal for every commit the expected cost is already over √N, and it approaches N as this ratio changes towards more proposals. Our second contribution is a new variant of propose and commit for\r\nTreeKEM which for moderate amounts of update proposals per commit provably achieves an update cost of Θ(log(N)) assuming the proposers and committers are chosen at random." acknowledgement: B.

The value of a strategy is the probability to satisfy the objective, here a parity objective, in the worst-case scenario, and the value of an MEMDP is the supremum of the values achievable by a strategy.\r\nWe show that deciding whether the value is 1 is a PSPACE-complete problem, and even in P when the number of environments is fixed, along with new insights to the almost-sure winning problem, which is to decide if there exists a strategy with value 1. Pure strategies are sufficient for theses problems, whereas randomization is necessary in general when the value is smaller than 1. We present an algorithm to approximate the value, running in double exponential space. Our results are in contrast to the related model of partially-observable MDPs where all these problems are known to be undecidable." acknowledgement: "Krishnendu Chatterjee: ERC CoG 863818 (ForM-SMArt) and Austrian Science Fund\r\n(FWF) 10.55776/COE12.

However, the quantitative relationship between this organization and nuclear biochemical processes remains under debate. In this study, we present a graph-based generative model, bioSBM, designed to capture long-range chromatin interaction patterns from Hi-C data and, importantly, simultaneously link these patterns to biochemical features. Applying bioSBM to Hi-C maps of the GM12878 lymphoblastoid cell line, we identified a latent structure of chromatin interactions, revealing seven distinct communities that strongly align with known biological annotations. Additionally, we infer a linear transformation that maps biochemical observables, such as histone marks, to the parameters of the generative graph model, enabling accurate genome-wide predictions of chromatin contact maps on out-of-sample data, both within the same cell line and on the completely unseen HCT116 cell line under RAD21 depletion. These findings highlight bioSBM's potential as a powerful tool for elucidating the relationship between biochemistry and chromatin architecture and predicting long-range genome organization from independent biochemical data. acknowledgement: G.S. acknowledges co-funding from Next Generation EU, in the context of the National Recovery and Resilience Plan, Investment PE1 - Project FAIR “Future Artificial Intelligence Research”.

Often, this challenge is framed as a combinatorial optimization problem, for which a common strategy employs simulated annealing, a Monte Carlo (MC)-based algorithm that updates spins one at a time. Yet, these localized updates can cause the system to become trapped in local minima. Cluster algorithms (CAs) were developed to address this limitation and have demonstrated considerable success in studying ferromagnetic systems; however, they tend to encounter percolation issues when applied to generic spin glasses. In this work, we introduce a novel CA designed to tackle these challenges by leveraging precomputed two-point correlations, aiming solve combinatorial optimization problems in the form of Max-Cut more efficiently. In our approach, clusters are formed probabilistically based on these correlations. Various classical and quantum algorithms can be employed to generate correlations that embody information about the energy landscape of the problem. By utilizing this information, the algorithm aims to identify groups of spins whose simultaneous flipping induces large transitions in configuration space with high acceptance probability - even at low energy levels - thereby escaping local minima more effectively. Notably, clusters generated using correlations from the Quantum Approximate Optimization Algorithm exhibit high acceptance rates at low temperatures. These acceptance rates often increase with circuit depth, accelerating the algorithm and enabling more efficient exploration of the solution space. acknowledgement: "P.J.E was partially funded by the German BMWK project QCHALLenge (Grant No. 01MQ22008B).\r\n" article_processing_charge: No arxiv: 1 author: - first_name: Peter J. full_name: Eder, Peter J. last_name: Eder - first_name: Aron full_name: Kerschbaumer, Aron id: ade85a9c-3200-11ee-973b-91c1eb240410 last_name: Kerschbaumer orcid: 0009-0002-2370-8661 - first_name: Jernej Rudi full_name: Finžgar, Jernej Rudi last_name: Finžgar - first_name: Raimel A full_name: Medina Ramos, Raimel A id: CE680B90-D85A-11E9-B684-C920E6697425 last_name: Medina Ramos orcid: 0000-0002-5383-2869 - first_name: Martin J.

This is the first algorithm to achieve polylogarithmic amortized update time for dense graphs (m = Ω(n²)), and more generally, for graphs where F^* = Õ(m/n). At the heart of our incremental algorithm is the residual graph sparsification technique of Karger and Levine [SICOMP '15], originally designed for computing exact maximum flows in the static setting. Our main contributions are (i) showing how to maintain such sparsifiers for approximate maximum flows in the incremental setting and (ii) generalizing the cut sparsification framework of Fung et al. [SICOMP '19] from undirected graphs to balanced directed graphs. acknowledgement: "Monika Henzinger and A. R.

A profile is an ε-Nash equilibrium if no player can gain more than ε by unilaterally deviating from their strategy. In this work, we use ε-Nash equilibria to approximate the computation of Nash equilibria. Specifically, we focus on turn-based, multiplayer stochastic games played on graphs, where players are restricted to stationary strategies - strategies that use randomness but not memory.\r\nThe problem of deciding the constrained existence of stationary Nash equilibria - where each player’s payoff must lie within a given interval - is known to be ∃ℝ-complete in such a setting (Hansen and Sølvsten, 2020). We extend this line of work to stationary ε-Nash equilibria and present an algorithm that solves the following promise problem: given a game with a Nash equilibrium satisfying the constraints, compute an ε-Nash equilibrium that ε-satisfies those same constraints - satisfies the constraints up to an ε additive error. Our algorithm runs in FNP^NP time.\r\nTo achieve this, we first show that if a constrained Nash equilibrium exists, then one exists where the non-zero probabilities are at least an inverse of a double-exponential in the input. We further prove that such a strategy can be encoded using floating-point representations, as in the work of Frederiksen and Miltersen (2013), which finally gives us our FNP^NP algorithm. \r\nWe further show that the decision version of the promise problem is NP-hard. Finally, we show a partial tightness result by proving a lower bound for such techniques: if a constrained Nash equilibrium exists, then there must be one where the probabilities in the strategies are double-exponentially small." acknowledgement: "This work is a part of project VAMOS that has received funding from the European\r\nResearch Council (ERC), grant agreement No 101020093.\r\n" alternative_title: - LIPIcs article_processing_charge: Yes arxiv: 1 author: - first_name: Ali full_name: Asadi, Ali id: 02d96aae-000e-11ec-b801-cadd0a5eefbb last_name: Asadi - first_name: Leonard full_name: Brice, Leonard last_name: Brice - first_name: Krishnendu full_name: Chatterjee, Krishnendu id: 2E5DCA20-F248-11E8-B48F-1D18A9856A87 last_name: Chatterjee orcid: 0000-0002-4561-241X - first_name: K.

For stars in particular, surface magnetism polarization that can be detected and measured with spectro-polarimetry. Many questions about these surface fields remain unanswered due to a lack of dedicated instruments capable of probing weak and strong surface magnetic fields for the entire mass range of stars, from M-dwarfs (and even substellar objects) to massive O-type stars at different evolutionary stages and metallicities. These questions range from the origin of these fields to their true incidence rate throughout the stellar population and the dependence on metallicity. Magnetic fields, although currently often excluded from stellar evolution models, play an important role in stellar evolution. Connecting the surface fields to internal fields through asteroseismology will instigate a new era of understanding stellar evolution and the transport of angular momentum and chemical elements throughout stellar interiors, also impacting our understanding of star-planet interactions and stellar remnants. Polarimetry is also an under-utilized tool to observationally constrain the mode identification of nonradial oscillations, which lies at the basis of accurate asteroseismic parameter estimation at percentage-level for stellar radii, masses, ages, internal rotation, and magnetic field strengths. Combining strong constraints on mode identification and surface magnetic properties through the acquisition of time-resolved, high-resolution and high-signal-to-noise (S/N) spectro-polarimetry and spectroscopy promises to bring leaps forward in our understanding of stellar structure, particularly when combined with long-term space photometric data from past, current, and future missions. article_number: '2512.15170' article_processing_charge: No arxiv: 1 author: - first_name: J. full_name: Vandersnickt, J. last_name: Vandersnickt - first_name: R.

Such short periods can only be reached if the donor star in the CV is either significantly evolved before initiating mass transfer to the WD or is metal-poor. We present optical photometry and spectroscopy of Gaia19bxc, a high-amplitude variable identified as a polar CV with an exceptionally short orbital period of 64.42 minutes—well below the canonical CV period minimum. High-speed photometry confirms persistent double-peaked variability consistent with cyclotron beaming, thus indicating the presence of a magnetic WD. Phase-resolved Keck/Low-Resolution Imaging Spectrometer (LRIS) spectroscopy reveals strong hydrogen and helium emission lines but no donor features, indicating the accretor is a magnetic WD and the donor is hydrogen-rich, but cold and faint. The absence of a detectable donor and the low inferred temperature (≲3500 K) disfavor an evolved donor scenario. Instead, the short period and the system’s halo-like kinematics suggest Gaia19bxc may be the first known metal-poor polar. Because metal-poor donors are more compact than solar-metallicity donors of the same mass, they can reach shorter minimum periods. Gaia19bxc is one of only a handful of known metal-poor CVs below the canonical period minimum and has the shortest period of any such magnetic system discovered to date. acknowledgement: "Based on observations obtained with the Samuel Oschin Telescope 48 inch and the 60 inch Telescope at the Palomar Observatory as part of the Zwicky Transient Facility project.

The wave function describing the motion of these objects must extend over a distance comparable to the slit separation, much larger than the characteristic size of the objects. Preparing such states for more massive objects, such as mechanical oscillators, remains an outstanding challenge. Here we delocalize the quantum ground state of an optically levitated nanosphere by modulating the stiffness of the confining potential. We show a more than threefold increase of the initial coherence length, which corresponds to mechanical momentum squeezing of more than 7 dB. Our work is a stepping stone toward the generation of coherence lengths comparable to the object size, a crucial regime for macroscopic quantum experiments. article_number: '083601' article_processing_charge: No article_type: original arxiv: 1 author: - first_name: M. full_name: Rossi, M. last_name: Rossi - first_name: Andrei full_name: Militaru, Andrei id: d67706f8-8eb1-11ee-ad1b-9c30dfa19e0b last_name: Militaru - first_name: N. full_name: Carlon Zambon, N. last_name: Carlon Zambon - first_name: A. full_name: Riera-Campeny, A. last_name: Riera-Campeny - first_name: O. full_name: Romero-Isart, O. last_name: Romero-Isart - first_name: M. full_name: Frimmer, M. last_name: Frimmer - first_name: L. full_name: Novotny, L. last_name: Novotny citation: ama: Rossi M, Militaru A, Carlon Zambon N, et al.

In the iid model, a gambler sees values in an online fashion, sampled independently from a given distribution. Upon observing each value, the gambler either accepts it as a reward, or irrevocably rejects it and proceeds to observe the next value. The goal of the gambler, who cannot see the future, is to maximise the expected value of the reward while competing against the expectation of a prophet (the offline maximum). In other words, one seeks to maximise the gambler-to-prophet ratio of the expectations. \r\nThis model has been studied with infinite, finite and unknown number of values. When the gambler faces a random number of values, the model is said to have a random horizon. We consider the model in which the gambler is given a priori knowledge of the horizon’s distribution. Alijani et al. (2020) designed a single-threshold algorithm achieving a ratio of 1/2 when the random horizon has an increasing hazard rate and is independent of the values. We prove that with a single threshold, a ratio of 1/2 is actually achievable for several larger classes of horizon distributions, with the largest being known as the \U0001D4A2 class in reliability theory. Moreover, we show that this does not extend to its dual, the ̅\U0001D4A2 class (which includes the decreasing hazard rate class), while it can be extended to low-variance horizons. Finally, we construct the first example of a family of horizons, for which multiple thresholds are necessary to achieve a nonzero ratio. We establish that the Secretary Problem optimal stopping rule provides one such algorithm, paving the way towards the study of the model beyond single-threshold algorithms." acknowledgement: 'We would like to thank José Correa for his precious advice, Bruno Ziliotto and Vasilis Livanos for early conversations.

This study presents a detailed comparative analysis of three strategies to promote the electrical transport properties of Cu3SbSe4 through Sn doping: conventional Sn atomic doping, surface treatment with SnSe molecular complexes, and blending with SnSe nanocrystals to form nanocomposites, all followed by annealing and hot pressing under identical conditions. Our results reveal that a surface treatment using SnSe molecular complexes significantly enhances TE performance over atomic doping and nanocomposite formation, achieving a power factor of 1.1 mW·m−1·K−2 and a maximum dimensionless figure of merit zT value of 0.80 at 640 K, representing an excellent performance among Cu3SbSe4-based materials produced via solution-processing methods. This work highlights the effectiveness of surface engineering in optimizing the transport properties of nanostructured materials, demonstrating the versatility and cost-efficiency of solution-based technologies in the development of advanced nanostructured materials for application in the field of TE among others.' acknowledgement: Y.

Higher load causes population numbers to decline, which reduces the efficiency of selection and further increases load, resulting in a positive feedback that may drive entire populations to extinction. Here, we investigate this eco-evolutionary feedback in a metapopulation consisting of local demes connected via migration, with individuals subject to deleterious mutation at a large number of loci. We first analyze the determinants of load under soft selection, where population sizes are fixed, and then build on this to understand hard selection, where population sizes and load coevolve. We show that under soft selection, very little gene flow (less than one migrant per generation) is enough to prevent fixation of deleterious alleles. By contrast, much higher levels of migration are required to mitigate load and prevent extinction when selection is hard, with critical migration thresholds for metapopulation persistence increasing sharply as the genome-wide deleterious mutation rate becomes comparable to the baseline population growth rate. Moreover, critical migration thresholds are highest if deleterious mutations have intermediate selection coefficients but lower if alleles are predominantly recessive rather than additive (due to more efficient purging of recessive load within local populations). Our analysis is based on a combination of analytical approximations and simulations, allowing for a more comprehensive understanding of the factors influencing load and extinction in fragmented populations. acknowledgement: 'This research was partially funded by the Austrian Science Fund (FWF P-32896B) and DOC Fellowships of the Austrian Academy of Sciences: grants 26380 (O.O.) and 26293 (K.K.).

By conceptualizing the proof technique of Lipmaa, Parisella, and Siim for the univariate KZG scheme (EUROCRYPT 2024), we present tools and falsifiable hardness assumptions that permit black-box extraction of the multivariate KZG scheme. Central to our approach is the notion of a canonical Proof-of-Knowledge of a Polynomial (PoKoP) of a polynomial commitment scheme, which we use to capture the extractability notion required in constructions of practical zk-SNARKs. We further present an explicit polynomial decomposition lemma for multivariate polynomials, enabling a more direct analysis of interpolating extractors and bridging the gap between univariate and multivariate commitments. Our results provide the first standard-model proofs of extractability for the multivariate KZG scheme and many of its variants under falsifiable assumptions. acknowledgement: Juraj Belohorec, Pavel Hubáček, and Kristýna Mašková were partially supported by the Academy of Sciences of the Czech Republic (RVO 67985840), Czech Science Foundation GAČR grant No. 25-16311S, and by Zircuit.

In this work, we provide a statistical characterization of this phenomenon for high-dimensional regression, when the data contains a predictive core feature x and a spurious feature y. Specifically, we quantify the amount of spurious correlations C learned via linear regression, in terms of the data covariance and the strength λ of the ridge regularization. As a consequence, we first capture the simplicity of y through the spectrum of its covariance, and its correlation with x through the Schur complement of the full data covariance. Next, we prove a trade-off between C and the in-distribution test loss L, by showing that the value of λ that minimizes L lies in an interval where C is increasing. Finally, we investigate the effects of over-parameterization via the random features model, by showing its equivalence to regularized linear regression. Our theoretical results are supported by numerical experiments on Gaussian, Color-MNIST, and CIFAR-10 datasets. acknowledgement: Marco Mondelli is funded by the European Union (ERC, INF2, project number 101161364).
