  text: Two standard models for probabilistic systems are Markov chains (MCs) and
    Markov decision processes (MDPs). Classic objectives for such probabilistic models
    for control and planning problems are reachability and stochastic shortest path.
    The widely studied algorithmic approach for these problems is the Value Iteration
    (VI) algorithm which iteratively applies local updates called Bellman updates.
    There are many practical approaches for VI in the literature but they all require
    exponentially many Bellman updates for MCs in the worst case. A preprocessing
    step is an algorithm that is discrete, graph-theoretical, and requires linear
    space. An important open question is whether, after a polynomial-time preprocessing,
    VI can be achieved with sub-exponentially many Bellman updates. In this work,
    we present a new approach for VI based on guessing values. Our theoretical contributions
    are twofold. First, for MCs, we present an almost-linear-time preprocessing algorithm
    after which, along with guessing values, VI requires only subexponentially many
    Bellman updates. Second, we present an improved analysis of the speed of convergence
    of VI for MDPs. Finally, we present a practical algorithm for MDPs based on our
    new approach. Experimental results show that our approach provides a considerable
    improvement over existing VI-based approaches on several benchmark examples from
    the literature.

  text: Statistical model checking estimates probabilities and expectations of interest
    in probabilistic system models by using random simulations. Its results come with
    statistical guarantees. However, many tools use unsound statistical methods that
    produce incorrect results more often than they claim. In this paper, we provide
    a comprehensive overview of tools and their correctness, as well as of sound methods
    available for estimating probabilities from the literature. For expected rewards,
    we investigate how to bound the path reward distribution to apply sound statistical
    methods for bounded distributions, of which we recommend the Dvoretzky-Kiefer-Wolfowitz
    inequality that has not been used in SMC so far. We prove that even reachability
    rewards can be bounded in theory, and formalise the concept of limit-PAC procedures
    for a practical solution. The modes SMC tool implements our methods and recommendations,
    which we use to experimentally confirm our results.

  text: The possibility of errors in human-engineered formal verification software,
    such as model checkers, poses a serious threat to the purpose of these tools.
    An established approach to mitigate this problem are certificates—lightweight,
    easy-to-check proofs of the verification results. In this paper, we develop novel
    certificates for model checking of Markov decision processes (MDPs) with quantitative
    reachability and expected reward properties. Our approach is conceptually simple
    and relies almost exclusively on elementary fixed point theory. Our certificates
    work for arbitrary finite MDPs and can be readily computed with little overhead
    using standard algorithms. We formalize the soundness of our certificates in Isabelle/HOL
    and provide a formally verified certificate checker. Moreover, we augment existing
    algorithms in the probabilistic model checker Storm with the ability to produce
    certificates and demonstrate practical applicability by conducting the first formal
    certification of the reference results in the Quantitative Verification Benchmark
    Set.

  text: We consider the problem of refuting equivalence of probabilistic programs,
    i.e., the problem of proving that two probabilistic programs induce different
    output distributions. We study this problem in the context of programs with conditioning
    (i.e., with observe and score statements), where the output distribution is conditioned
    by the event that all the observe statements along a run evaluate to true, and
    where the probability densities of different runs may be updated via the score
    statements. Building on a recent work on programs without conditioning, we present
    a new equivalence refutation method for programs with conditioning. Our method
    is based on weighted restarting, a novel transformation of probabilistic programs
    with conditioning to the output equivalent probabilistic programs without conditioning
    that we introduce in this work. Our method is the first to be both a) fully automated,
    and b) providing provably correct answers. We demonstrate the applicability of
    our method on a set of programs from the probabilistic inference literature.

  text: Snow cover is of key importance for water resources in high mountain Asia
    (HMA) and is expected to undergo extensive changes in a warming climate. Past
    studies have quantified snow cover changes with satellite products of relatively
    low spatial resolution (∼500 m) which are hindered by the steep topography of
    this mountain region. We derive snowlines from Sentinel-2 and Landsat 5, 7 and
    8 images, which, thanks to their higher spatial resolution, are less sensitive
    to the local topography. We calculate the snow line altitude (SLA) and its seasonality
    for all glacierized catchments of HMA and link these patterns to climate variables
    corrected for topographic biases. As such, the snowline changes provide a clear
    proxy for climatic changes. Our results highlight a strong spatial variability
    in mean SLA and in its seasonal changes, including across mountain chains and
    between the monsoon-dominated and the westerlies-dominated catchments. Over the
    period 1999–2019, the western regions of HMA (Pamir, Karakoram, Western Himalaya)
    have undergone increased snow coverage, expressed as seasonal SLA decrease, in
    spring and summer. This change is opposed to a widespread increase in SLA in autumn
    across the region, and especially the southeastern regions of HMA (Nyainqentanglha,
    Hengduan Shan, South–East Himalaya). Our results indicate that the diversity of
    seasonal snow dynamics across the region is controlled not by temperature or precipitation
    directly but by the timing and partitioning of solid precipitation. Decadal snowline
    changes (1999–2009 vs 2009–2019) seasonally precede temperature changes, suggesting
    that seasonal temperature changes in the Karakoram–Pamir and Eastern Nyainqentanglha
    regions may have responded to snow cover changes, rather than driving them.

  text: "A verifiable delay function VDF(x, T)->(y, π) maps an input x and time parameter
    T to an output y together with an efficiently verifiable proof π certifying that
    y was correctly computed. The function runs in T sequential steps, and it should
    not be possible to compute y much faster than that. The only known practical VDFs
    use sequential squaring in groups of unknown order as the sequential function,
    i.e., y = x^2^T. There are two constructions for the proof of exponentiation (PoE)
    certifying that y = x^2^T, with Wesolowski (Eurocrypt’19) having very short proofs,
    but they are more expensive to compute and the soundness relies on stronger assumptions
    than the PoE proposed by Pietrzak (ITCS’19).\r\nA recent application of VDFs by
    Arun, Bonneau and Clark (Asiacrypt’22) are short-lived proofs and signatures,
    which are proofs and signatures that are only sound for some time t, but after
    that can be forged by anyone. For this they rely on “watermarkable VDFs”, where
    the proof embeds a prover chosen watermark. To achieve stronger notions of proofs/signatures
    with reusable forgeability, they rely on “zero-knowledge VDFs”, where instead
    of the output y, one just proves knowledge of this output. The existing proposals
    for watermarkable and zero-knowledge VDFs all build on Wesolowski’s PoE, for the
    watermarkable VDFs there’s currently no security proof.\r\n\r\nIn this work we
    give the first constructions that transform any PoEs in hidden order groups into
    watermarkable VDFs and into zkVDFs, solving an open question by Arun et al. Unlike
    our watermarkable VDF, the zkVDF (required for reusable forgeability) is not very
    practical as the number of group elements in the proof is a security parameter.
    To address this, we introduce the notion of zero-knowledge proofs of sequential
    work (zkPoSW), a notion that relaxes zkVDFs by not requiring that the output is
    unique. We show that zkPoSW are sufficient to construct proofs or signatures with
    reusable forgeability, and construct efficient zkPoSW from any PoE, ultimately
    achieving short lived proofs and signatures that improve upon Arun et al.’s construction
    in several dimensions (faster forging times, arguably weaker assumptions).\r\nA
    key idea underlying our constructions is to not directly construct a (watermarked
    or zk) proof for y = x^2^T, but instead give a (watermarked or zk) proof for the
    more basic statement that \r\nx^l, y^l satisfy x^l = x ^r, y^l = y^r for some
    r, together with a normal PoE for y^l = (x^l)^2^T."

  text: The transverse thermoelectric (Nernst) effect is a powerful probe for studying
    the electronic and structural properties of materials. In this study, we employ
    transverse thermoelectric measurements to investigate the ferroelectric distortion
    in the topological crystalline insulator (TCI) Pb0.60Sn0.40Te, a compound derived
    from PbTe and SnTe, known for their exceptional thermoelectric performance and
    distinct ferroelectric properties. By leveraging Nernst measurements, we provide
    direct evidence of ferroelectric distortion in this TCI, corroborated by Shubnikov–de
    Haas quantum oscillations that confirm the presence of two topologically nontrivial
    Fermi pockets. Density functional theory calculations show that these pockets
    originate from the L and T points in the Brillouin zone of the distorted structure
    within the TCI phase. Raman spectroscopy further identifies a structural phase
    transition below 50 K, consistent with the quantum oscillation observations. This
    observation is further substantiated by temperature-dependent synchrotron X-ray
    pair distribution function analysis and transmission electron microscopy, which
    confirm the local off-centering of cations at low temperature. These findings
    underscore the potential of transverse thermoelectric measurements in unveiling
    ferroelectric distortions and their role in modulating topological quantum states,
    opening new directions for research into the synergy between ferroelectricity
    and topological phases.

  text: We consider a local Cahn–Hilliard‐type model for tumor growth as well as a
    nonlocal model where, compared to the local system, the Laplacian in the equation
    for the chemical potential is replaced by a nonlocal operator. The latter is defined
    as a convolution integral with suitable kernels parametrized by a small parameter.
    For sufficiently smooth bounded domains in three dimensions, we prove convergence
    of weak solutions of the nonlocal model toward strong solutions of the local model
    together with convergence rates with respect to the small parameter. The proof
    is done via a Gronwall‐type argument and a convergence result with rates for the
    nonlocal integral operator toward the Laplacian due to Abels and Hurm.

  text: 'We present the Red Unknowns: Bright Infrared Extragalactic Survey (RUBIES)
    providing JWST/NIRSpec spectroscopy of red sources selected across ∼150 arcmin2
    from public JWST/NIRCam imaging in the UDS and EGS fields. The novel observing
    strategy of RUBIES offers a well-quantified selection function. The survey has
    been optimised to reach high (>70%) spectroscopic completeness for bright and
    red (F150W−F444W>2) sources that are very rare. To place these rare sources in
    context, we simultaneously observed a reference sample of the 2<z<7 galaxy population,
    sampling sources at a rate that is inversely proportional to their number density
    in the 3D parameter space of F444W magnitude, F150W−F444W colour, and photometric
    redshift. In total, RUBIES observed ∼3000 targets across 1<zphot<10 with both
    the PRISM and G395M dispersers and ∼1500 targets at zphot>3 using only the G395M
    disperser. The RUBIES data reveal a highly diverse population of red sources that
    span a broad redshift range (zspec∼1−9), with photometric redshift scatter and
    an outlier fraction that are three times higher than for similarly bright sources
    that are less red. This diversity is not apparent from the photometric spectral
    energy distributions (SEDs). Only spectroscopy reveals that the SEDs encompass
    a mixture of galaxies with dust-obscured star formation, extreme line emission,
    a lack of star formation indicating early quenching, and luminous active galactic
    nuclei. As a first demonstration of our broader selection function we compared
    the stellar masses and rest-frame U−V colours of the red sources and our reference
    sample. We find that the red sources are typically more massive (M*∼1010−11.5 M⊙)
    across all redshifts. However, we also find that the most massive systems span
    a wide range in U−V colour. We describe our data reduction procedure and data
    quality, and we publicly release the reduced RUBIES data and vetted spectroscopic
    redshifts of the first half of the survey through the DAWN JWST Archive.'

  text: Confinement is a prominent phenomenon in condensed matter and high-energy
    physics that has recently become the focus of quantum-simulation experiments of
    lattice gauge theories (LGTs). As such, a theoretical understanding of the effect
    of confinement on LGT dynamics is not only of fundamental importance, but can
    lend itself to upcoming experiments. Here, we show how confinement in a Z2 LGT
    can be locally avoided by proximity to a resonance between the fermion mass and
    the electric field strength. Furthermore, we show that this local deconfinement
    can become global for certain initial conditions, where information transport
    occurs over the entire chain. In addition, we show how this can lead to strong
    quantum many-body scarring starting in different initial states. Our findings
    provide deeper insights into the nature of confinement in Z2 LGTs and can be tested
    on current and near-term quantum devices.

  text: Status epilepticus (SE), seizures lasting beyond five minutes, is a medical
    emergency commonly treated with benzodiazepines which enhance GABAA receptor (GABAAR)
    conductance. Despite widespread use, benzodiazepines fail in over one-third of
    patients, potentially due to seizure-induced disruption of neuronal chloride (Cl−)
    homeostasis. Understanding these changes at a network level is crucial for improving
    clinical translation. Here, we address this using a large-scale spiking neural
    network model incorporating Cl− dynamics, informed by clinical EEG and experimental
    slice recordings. Our simulations confirm that the GABAAR reversal potential (EGABA)
    dictates the pro- or anti-seizure effect of GABAAR conductance modulation, with
    high EGABA rendering benzodiazepines ineffective or excitatory. We show SE-like
    activity and EGABA depend non-linearly on Cl− extrusion efficacy and GABAAR conductance.
    Critically, cell-type specific manipulations reveal that pyramidal cell, not interneuron,
    Cl− extrusion predominantly determines the severity of SE activity and the response
    to simulated benzodiazepines. Leveraging these mechanistic insights, we develop
    a predictive framework mapping network states to Cl− extrusion capacity and GABAergic
    load, yielding a proposed decision-making strategy to guide therapeutic interventions
    based on initial treatment response. This work identifies pyramidal cell Cl− handling
    as a key therapeutic target and demonstrates the utility of biophysically detailed
    network models for optimising SE treatment protocols.

  text: "Motivation: Boolean networks are popular dynamical models of cellular processes
    in systems biology. Their attractors model phenotypes that arise from the interplay
    of key regulatory subcircuits. A succession diagram (SD) describes this interplay
    in a discrete analog of Waddington’s epigenetic attractor landscape that allows
    for fast identification of attractors and attractor control strategies. Efficient
    computational tools for studying SDs are essential for the understanding of Boolean
    attractor landscapes and connecting them to their biological functions.\r\nResults:
    We present a new approach to SD construction for asynchronously updated Boolean
    networks, implemented in the biologist’s Boolean attractor landscape mapper, biobalm.
    We compare biobalm to similar tools and find a substantial performance increase
    in SD construction, attractor identification, and attractor control. We perform
    the most comprehensive comparative analysis to date of the SD structure in experimentally-validated
    Boolean models of cell processes and random ensembles. We find that random models
    (including critical Kauffman networks) have relatively small SDs, indicating simple
    decision structures. In contrast, nonrandom models from the literature are enriched
    in extremely large SDs, indicating an abundance of decision points and suggesting
    the presence of complex Waddington landscapes in nature.\r\nAvailability and implementation:
    The tool biobalm is available online at https://github.com/jcrozum/biobalm. Further
    data, scripts for testing, analysis, and figure generation are available online
    at https://github.com/jcrozum/biobalm-analysis and in the reproducibility artefact

  text: Stars stripped of their hydrogen-rich envelopes through binary interaction
    are thought to be responsible for both hydrogen-poor supernovae and the hard ionizing
    radiation observed in low-Z galaxies. A population of these stars was recently
    observed for the first time, but their prevalence remains unknown. In preparation
    for such measurements, we estimate the mass distribution of hot, stripped stars
    using a population synthesis code that interpolates over detailed single and binary
    stellar evolution tracks. We predict that for a constant star formation rate of
    1 M⊙/yr and regardless of metallicity, a scalable model population contains ∼30
    000 stripped stars with mass Mstrip > 1 M⊙ and ∼4000 stripped stars that are sufficiently
    massive to explode (Mstrip > 2.6 M⊙). Below Mstrip = 5 M⊙, the distribution is
    metallicity-independent and can be described by a power law with the exponent
    α ∼ −2. At higher masses and lower metallicity (Z ≲ 0.002), the mass distribution
    exhibits a drop. This originates from the prediction, frequently seen in evolutionary
    models, that massive low-metallicity stars do not expand substantially until central
    helium burning or later and therefore cannot form long-lived stripped stars. With
    weaker line-driven winds at low metallicity, this suggests that neither binary
    interaction nor wind mass loss can efficiently strip massive stars at low metallicity.
    As a result, a “helium-star desert” emerges around Mstrip = 15 M⊙ at Z = 0.002,
    covering an increasingly large mass range with decreasing metallicity. We note
    that these high-mass stars are those that potentially boost a galaxy’s He+-ionizing
    radiation and that participate in the formation of merging black holes. This “helium-star
    desert” therefore merits further study.

  text: In an  n×n  array filled with symbols, a transversal is a collection of entries
    with distinct rows, columns and symbols. In this note we show that if no symbol
    appears more than  βn  times, the array contains a transversal of size  (1−β/4−o(1))n
    . In particular, if the array is filled with  n  symbols, each appearing  n  times
    (an equi- n  square), we get transversals of size  (3/4−o(1))n. Moreover, our
    proof gives a deterministic algorithm with polynomial running time, that finds
    these transversals.

  text: Eigenstates of quantum many-body systems are often used to define phases of
    matter in and out of equilibrium; however, experimentally accessing highly excited
    eigenstates is a challenging task, calling for alternative strategies to dynamically
    probe nonequilibrium phases. In this work, we characterize the dynamical properties
    of a disordered spin chain, focusing on the spin-glass regime. Using tensor-network
    simulations, we observe oscillatory behavior of local expectation values and bipartite
    entanglement entropy. We explain these oscillations deep in the many-body localized
    spin-glass regime via a simple theoretical model. From perturbation theory, we
    predict the timescales up to which our analytical description is valid and confirm
    it with numerical simulations. Finally, we study the correlation length dynamics,
    which, after a long-time plateau, resume growing in line with renormalization
    group (RG) expectations. Our work suggests that RG predictions can be quantitatively
    tested against numerical simulations and experiments, potentially enabling microscopic
    descriptions of dynamical phases in large systems.

  text: The snow and glaciers of the Peruvian Andes provide vital water supplies in
    a region facing water scarcity and substantial glacier change. However, there
    remains a lack of understanding of snow processes and quantification of the contribution
    of melt to runoff. Here we apply a distributed glacio-hydrological model over
    the Rio Santa basin to disentangle the role of the cryosphere in the Andean water
    cycle. Only at the highest elevations (>5000 m a.s.l.) is the snow cover continuous;
    at lower elevations, the snowpack is thin and ephemeral, with rapid cycles of
    snowfall and melt. Due to the large catchment area affected by ephemeral snow,
    its contribution to catchment inputs is substantial (23% and 38% in the wet and
    dry season, respectively). Ice melt is crucial in the mid-dry season (up to 44%
    of inputs). Our results improve estimates of water fluxes and call for further
    process-based modelling across the Andes.

  text: "We report the discovery of two new magnetic cataclysmic variables with brown
    dwarf companions and long orbital periods (P_{\\rm orb}=95\\pm1 and 104\\pm2 min).
    This discovery increases the sample of candidate magnetic period bouncers with
    confirmed sub-stellar donors from four to six. We also find their X-ray luminosity
    from archival XMM–Newton observations to be in the range L_{\\rm X}\\approx10^{28}-10^{29}
    \\mathrm{erg\\,s^{-1}} in the 0.25–10 keV band. This low luminosity is comparable
    with the other candidates, and at least an order of magnitude lower than the X-ray
    luminosities typically measured in cataclysmic variables. The X-ray fluxes imply
    mass transfer rates that are much lower than predicted by evolutionary models,
    even if some of the discrepancy is due to the accretion energy being emitted in
    other bands, such as via cyclotron emission at infrared wavelengths. Although
    it is possible that some or all of these systems formed directly as binaries containing
    a brown dwarf, it is likely that the donor used to be a low-mass star and that
    the systems followed the evolutionary track for cataclysmic variables, evolving
    past the period bounce. The donor in long period systems is expected to be a low-mass,
    cold brown dwarf. This hypothesis is supported by near-infrared photometric observations
    that constrain the donors in the two systems to be brown dwarfs cooler than \r\n1100 K
    (spectral types T5 or later), most likely losing mass via Roche Lobe overflow
    or winds. The serendipitous discovery of two magnetic period bouncers in the small
    footprint of the XMM–Newton catalogue implies a large space density of these type
    of systems, possibly compatible with the prediction of 40–70 per cent of magnetic
    cataclysmic variables to be period bouncers."
