  text: 'Robustness to variations in lighting conditions is a key objective for any
    deep vision system. To this end, our paper extends the receptive field of convolutional
    neural networks with two residual components, ubiquitous in the visual processing
    system of vertebrates: On-center and off-center pathways, with an excitatory center
    and inhibitory surround; OOCS for short. The On-center pathway is excited by the
    presence of a light stimulus in its center, but not in its surround, whereas the
    Off-center pathway is excited by the absence of a light stimulus in its center,
    but not in its surround. We design OOCS pathways via a difference of Gaussians,
    with their variance computed analytically from the size of the receptive fields.
    OOCS pathways complement each other in their response to light stimuli, ensuring
    this way a strong edge-detection capability, and as a result an accurate and robust
    inference under challenging lighting conditions. We provide extensive empirical
    evidence showing that networks supplied with OOCS pathways gain accuracy and illumination-robustness
    from the novel edge representation, compared to other baselines.'

  text: "We show that Neural ODEs, an emerging class of timecontinuous neural networks,
    can be verified by solving a set of global-optimization problems. For this purpose,
    we introduce Stochastic Lagrangian Reachability (SLR), an\r\nabstraction-based
    technique for constructing a tight Reachtube (an over-approximation of the set
    of reachable states\r\nover a given time-horizon), and provide stochastic guarantees
    in the form of confidence intervals for the Reachtube bounds. SLR inherently avoids
    the infamous wrapping effect (accumulation of over-approximation errors) by performing
    local optimization steps to expand safe regions instead of repeatedly forward-propagating
    them as is done by deterministic reachability methods. To enable fast local optimizations,
    we introduce a novel forward-mode adjoint sensitivity method to compute gradients
    without the need for backpropagation. Finally, we establish asymptotic and non-asymptotic
    convergence rates for SLR."

  text: "Imitation learning enables high-fidelity, vision-based learning of policies
    within rich, photorealistic environments. However, such techniques often rely
    on traditional discrete-time neural models and face difficulties in generalizing
    to domain shifts by failing to account for the causal relationships between the
    agent and the environment. In this paper, we propose a theoretical and experimental
    framework for learning causal representations using continuous-time neural networks,
    specifically over their discrete-time counterparts. We evaluate our method in
    the context of visual-control learning of drones over a series of complex tasks,
    ranging from short- and long-term navigation, to chasing static and dynamic objects
    through photorealistic environments. Our results demonstrate that causal continuous-time\r\ndeep
    models can perform robust navigation tasks, where advanced recurrent models fail.
    These models learn complex causal control representations directly from raw visual
    inputs and scale to solve a variety of tasks using imitation learning."

  text: We introduce a new class of time-continuous recurrent neural network models.
    Instead of declaring a learning system’s dynamics by implicit nonlinearities,
    we construct networks of linear first-order dynamical systems modulated via nonlinear
    interlinked gates. The resulting models represent dynamical systems with varying
    (i.e., liquid) time-constants coupled to their hidden state, with outputs being
    computed by numerical differential equation solvers. These neural networks exhibit
    stable and bounded behavior, yield superior expressivity within the family of
    neural ordinary differential equations, and give rise to improved performance
    on time-series prediction tasks. To demonstrate these properties, we first take
    a theoretical approach to find bounds over their dynamics, and compute their expressive
    power by the trajectory length measure in a latent trajectory space. We then conduct
    a series of time-series prediction experiments to manifest the approximation capability
    of Liquid Time-Constant Networks (LTCs) compared to classical and modern RNNs.

  text: 'In two-player games on graphs, the players move a token through a graph to
    produce an infinite path, which determines the winner of the game. Such games
    are central in formal methods since they model the interaction between a non-terminating
    system and its environment. In bidding games the players bid for the right to
    move the token: in each round, the players simultaneously submit bids, and the
    higher bidder moves the token and pays the other player. Bidding games are known
    to have a clean and elegant mathematical structure that relies on the ability
    of the players to submit arbitrarily small bids. Many applications, however, require
    a fixed granularity for the bids, which can represent, for example, the monetary
    value expressed in cents. We study, for the first time, the combination of discrete-bidding
    and infinite-duration games. Our most important result proves that these games
    form a large determined subclass of concurrent games, where determinacy is the
    strong property that there always exists exactly one player who can guarantee
    winning the game. In particular, we show that, in contrast to non-discrete bidding
    games, the mechanism with which tied bids are resolved plays an important role
    in discrete-bidding games. We study several natural tie-breaking mechanisms and
    show that, while some do not admit determinacy, most natural mechanisms imply
    determinacy for every pair of initial budgets.'

  text: "Civl is a static verifier for concurrent programs designed around the conceptual
    framework of layered refinement,\r\nwhich views the task of verifying a program
    as a sequence of program simplification steps each justified by its own invariant.
    Civl verifies a layered concurrent program that compactly expresses all the programs
    in this sequence and the supporting invariants. This paper presents the design
    and implementation of the Civl verifier."

  text: We experimentally investigate narrow and topologically nontrivial moiré minibands
    hosted by van der Waals heterostructures consisting of a graphene monolayer rotationally
    faulted with respect to a Bernal-stacked bilayer. At fillings ν= 1 and 3 electrons
    per moiré unit cell within these bands, we observe quantized anomalous Hall effects
    with Rxy≈h/2e2, indicative of spontaneous polarization of the system into a single
    valley-projected band with Chern number C= 2. Remarkably, we also observe the
    evidence of symmetry broken Chern insulator states at ν= 1.5 and 3.5. At ν= 3
    we find that the sign of the quantum anomalous Hall effect can be reversed via
    field-effect control of the chemical potential. This curious effect arises from
    the magnetization contribution due to topological edge states, which drive a reversal
    of the total magnetization and thus a switch of the favored magnetic state. Remarkably,
    we find that this switch is hysteretic, which we use to demonstrate non-volatile
    electric-field-induced reversal of the magnetic state. Voltage control of magnetic
    states can be used to electrically pattern nonvolatile magnetic domain structures
    hosting chiral edge states, with applications ranging from reconfigurable microwave
    circuit elements to ultra-low-power magnetic memory.

  text: 'In a two-player zero-sum graph game the players move a token throughout a
    graph to produce an infinite path, which determines the winner or payoff of the
    game. Traditionally, the players alternate turns in moving the token. In bidding
    games, however, the players have budgets, and in each turn, we hold an “auction”
    (bidding) to determine which player moves the token: both players simultaneously
    submit bids and the higher bidder moves the token. The bidding mechanisms differ
    in their payment schemes. Bidding games were largely studied with variants of
    first-price bidding in which only the higher bidder pays his bid. We focus on
    all-pay bidding, where both players pay their bids. Finite-duration all-pay bidding
    games were studied and shown to be technically more challenging than their first-price
    counterparts. We study for the first time, infinite-duration all-pay bidding games.
    Our most interesting results are for mean-payoff objectives: we portray a complete
    picture for games played on strongly-connected graphs. We study both pure (deterministic)
    and mixed (probabilistic) strategies and completely characterize the optimal and
    almost-sure (with probability 1) payoffs the players can respectively guarantee.
    We show that mean-payoff games under all-pay bidding exhibit the intriguing mathematical
    properties of their first-price counterparts; namely, an equivalence with random-turn
    games in which in each turn, the player who moves is selected according to a (biased)
    coin toss. The equivalences for all-pay bidding are more intricate and unexpected
    than for first-price bidding.'

  text: In this paper, we investigate the distribution of the maximum of partial sums
    of families of  m -periodic complex-valued functions satisfying certain conditions.
    We obtain precise uniform estimates for the distribution function of this maximum
    in a near-optimal range. Our results apply to partial sums of Kloosterman sums
    and other families of  ℓ -adic trace functions, and are as strong as those obtained
    by Bober, Goldmakher, Granville and Koukoulopoulos for character sums. In particular,
    we improve on the recent work of the third author for Birch sums. However, unlike
    character sums, we are able to construct families of  m -periodic complex-valued
    functions which satisfy our conditions, but for which the Pólya–Vinogradov inequality
    is sharp.

  text: We prove an adiabatic theorem for the Landau–Pekar equations. This allows
    us to derive new results on the accuracy of their use as effective equations for
    the time evolution generated by the Fröhlich Hamiltonian with large coupling constant
    α. In particular, we show that the time evolution of Pekar product states with
    coherent phonon field and the electron being trapped by the phonons is well approximated
    by the Landau–Pekar equations until times short compared to α2.

  text: Methods inspired from machine learning have recently attracted great interest
    in the computational study of quantum many-particle systems. So far, however,
    it has proven challenging to deal with microscopic models in which the total number
    of particles is not conserved. To address this issue, we propose a new variant
    of neural network states, which we term neural coherent states. Taking the Fröhlich
    impurity model as a case study, we show that neural coherent states can learn
    the ground state of non-additive systems very well. In particular, we observe
    substantial improvement over the standard coherent state estimates in the most
    challenging intermediate coupling regime. Our approach is generic and does not
    assume specific details of the system, suggesting wide applications.

  text: Given the abundance of applications of ranking in recent years, addressing
    fairness concerns around automated ranking systems becomes necessary for increasing
    the trust among end-users. Previous work on fair ranking has mostly focused on
    application-specific fairness notions, often tailored to online advertising, and
    it rarely considers learning as part of the process. In this work, we show how
    to transfer numerous fairness notions from binary classification to a learning
    to rank setting. Our formalism allows us to design methods for incorporating fairness
    objectives with provable generalization guarantees. An extensive experimental
    evaluation shows that our method can improve ranking fairness substantially with
    no or only little loss of model quality.

  text: Ligands are a fundamental part of nanocrystals. They control and direct nanocrystal
    syntheses and provide colloidal stability. Bound ligands also affect the nanocrystals’
    chemical reactivity and electronic structure. Surface chemistry is thus crucial
    to understand nanocrystal properties and functionality. Here, we investigate the
    synthesis of metal oxide nanocrystals (CeO2-x, ZnO, and NiO) from metal nitrate
    precursors, in the presence of oleylamine ligands. Surprisingly, the nanocrystals
    are capped exclusively with a fatty acid instead of oleylamine. Analysis of the
    reaction mixtures with nuclear magnetic resonance spectroscopy revealed several
    reaction byproducts and intermediates that are common to the decomposition of
    Ce, Zn, Ni, and Zr nitrate precursors. Our evidence supports the oxidation of
    alkylamine and formation of a carboxylic acid, thus unraveling this counterintuitive
    surface chemistry.

  text: Thermoelectric materials are engines that convert heat into an electrical
    current. Intuitively, the efficiency of this process depends on how many electrons
    (charge carriers) can move and how easily they do so, how much energy those moving
    electrons transport, and how easily the temperature gradient is maintained. In
    terms of material properties, an excellent thermoelectric material requires a
    high electrical conductivity σ, a high Seebeck coefficient S (a measure of the
    induced thermoelectric voltage as a function of temperature gradient), and a low
    thermal conductivity κ. The challenge is that these three properties are strongly
    interrelated in a conflicting manner (1). On page 722 of this issue, Roychowdhury
    et al. (2) have found a way to partially break these ties in silver antimony telluride
    (AgSbTe2) with the addition of cadmium (Cd) cations, which increase the ordering
    in this inherently disordered thermoelectric material.

  text: Basket weaving is a traditional craft for creating curved surfaces as an interwoven
    array of thin, flexible, and initially straight ribbons. The three-dimensional
    shape of a woven structure emerges through a complex interplay of the elastic
    bending behavior of the ribbons and the contact forces at their crossings. Curvature
    can be injected by carefully placing topological singularities in the otherwise
    regular weaving pattern. However, shape control through topology is highly non-trivial
    and inherently discrete, which severely limits the range of attainable woven geometries.
    Here, we demonstrate how to construct arbitrary smooth free-form surface geometries
    by weaving carefully optimized curved ribbons. We present an optimization-based
    approach to solving the inverse design problem for such woven structures. Our
    algorithm computes the ribbons' planar geometry such that their interwoven assembly
    closely approximates a given target design surface in equilibrium. We systematically
    validate our approach through a series of physical prototypes to show a broad
    range of new woven geometries that is not achievable by existing methods. We anticipate
    our computational approach to significantly enhance the capabilities for the design
    of new woven structures. Facilitated by modern digital fabrication technology,
    we see potential applications in material science, bio- and mechanical engineering,
    art, design, and architecture.

  text: Inspired by motion patterns of some commercially available mobile robots,
    we investigate the power of robots that move forward in straight lines until colliding
    with an environment boundary, at which point they can rotate in place and move
    forward again; we visualize this as the robot “bouncing” off boundaries. We define
    bounce rules governing how the robot should reorient after reaching a boundary,
    such as reorienting relative to its heading prior to collision, or relative to
    the normal of the boundary. We then generate plans as sequences of rules, using
    the bounce visibility graph generated from a polygonal environment definition,
    while assuming we have unavoidable non-determinism in our actuation. Our planner
    can be queried to determine the feasibility of tasks such as reaching goal sets
    and patrolling (repeatedly visiting a sequence of goals). If the task is found
    feasible, the planner provides a sequence of non-deterministic interaction rules,
    which also provide information on how precisely the robot must execute the plan
    to succeed. We also show how to compute stable cyclic trajectories and use these
    to limit uncertainty in the robot’s position. </jats:p>

  text: "Given the central role that C continues to play in systems software, and
    the difficulty of writing safe and correct C code, it remains a grand challenge
    to develop effective formal methods for verifying C programs. In this paper, we
    propose a new approach to this problem: a type system we call RefinedC, which
    combines ownership types (for modular reasoning about shared state and concurrency)
    with refinement types (for encoding precise invariants on C data types and Hoare-style
    specifications for C functions).\r\nRefinedC is both automated (requiring minimal
    user intervention) and foundational (producing a proof of program correctness
    in Coq), while at the same time handling a range of low-level programming idioms
    such as pointer arithmetic. In particular, following the approach of RustBelt,
    the soundness of the RefinedC type system is justified semantically by interpretation
    into the Coq-based Iris framework for higher-order concurrent separation logic.
    However, the typing rules of RefinedC are also designed to be encodable in a new
    “separation logic programming” language we call Lithium. By restricting to a carefully
    chosen (yet expressive) fragment of separation logic, Lithium supports predictable,
    automatic, goal-directed proof search without backtracking. We demonstrate the
    effectiveness of RefinedC on a range of representative examples of C code."

  text: "This paper presents the ESA Voyage 2050 White Paper for a concept of TeraHertz
    Exploration and Zooming-in for Astrophysics (THEZA). It addresses the science
    case and some implementation issues of a space-borne radio interferometric system
    for ultra-sharp imaging of celestial radio sources at the level of angular resolution
    down to (sub-) microarcseconds. THEZA focuses at millimetre and sub-millimetre
    wavelengths (frequencies above \r\n300 GHz), but allows for science operations
    at longer wavelengths too. The THEZA concept science rationale is focused on the
    physics of spacetime in the vicinity of supermassive black holes as the leading
    science driver. The main aim of the concept is to facilitate a major leap by providing
    researchers with orders of magnitude improvements in the resolution and dynamic
    range in direct imaging studies of the most exotic objects in the Universe, black
    holes. The concept will open up a sizeable range of hitherto unreachable parameters
    of observational astrophysics. It unifies two major lines of development of space-borne
    radio astronomy of the past decades: Space VLBI (Very Long Baseline Interferometry)
    and mm- and sub-mm astrophysical studies with “single dish” instruments. It also
    builds upon the recent success of the Earth-based Event Horizon Telescope (EHT)
    – the first-ever direct image of a shadow of the super-massive black hole in the
    centre of the galaxy M87. As an amalgam of these three major areas of modern observational
    astrophysics, THEZA aims at facilitating a breakthrough in high-resolution high
    image quality studies in the millimetre and sub-millimetre domain of the electromagnetic
    spectrum."

  text: The recently discovered gravitational wave sources GW190521 and GW190814 have
    shown evidence of BH mergers with masses and spins outside of the range expected
    from isolated stellar evolution. These merging objects could have undergone previous
    mergers. Such hierarchical mergers are predicted to be frequent in active galactic
    nuclei (AGNs) disks, where binaries form and evolve efficiently by dynamical interactions
    and gaseous dissipation. Here we compare the properties of these observed events
    to the theoretical models of mergers in AGN disks, which are obtained by performing
    one-dimensional N-body simulations combined with semi-analytical prescriptions.
    The high BH masses in GW190521 are consistent with mergers of high-generation
    (high-g) BHs where the initial progenitor stars had high metallicity, 2g BHs if
    the original progenitors were metal-poor, or 1g BHs that had gained mass via super-Eddington
    accretion. Other measured properties related to spin parameters in GW190521 are
    also consistent with mergers in AGN disks. Furthermore, mergers in the lower mass
    gap or those with low mass ratio as found in GW190814 and GW190412 are also reproduced
    by mergers of 2g–1g or 1g–1g objects with significant accretion in AGN disks.
    Finally, due to gas accretion, the massive neutron star merger reported in GW190425
    can be produced in an AGN disk.

  text: 'The disks of active galactic nuclei (AGNs) have emerged as a rich environment
    for the evolution of stars and their compact remnants. The very dense medium favors
    rapid accretion, while torques and migration traps enhance binary formation and
    mergers. Both long and short gamma-ray bursts are hence expected. We show that
    AGN disks constitute an ideal environment for another interesting phenomenon:
    the accretion-induced collapse (AIC) of neutron stars (NSs) to black holes (BHs).
    Rapid accretion in the dense disks can cause NSs to grow to the point of exceeding
    the maximum mass allowed by their equation of state. General relativistic magnetohydrodynamical
    simulations have shown that electromagnetic signatures are expected if the NS
    is surrounded by a minidisk prior to collapse, which then rapidly accretes onto
    the BH, and/or if the NS is highly magnetized, from reconnection of the magnetosphere
    during collapse. Here we compute the rates of AICs and their locations within
    the disks for both isolated NSs and for (initially stable) NSs formed from NS-NS
    mergers. We find that the global AIC rates are ∼0.07–20 Gpc−3 yr−1, and we discuss
    their observable prospects and signatures as they emerge from the dense disk environments.'
