  text: We consider the quantum many-body evolution of a homogeneous Fermi gas in
    three dimensions in the coupled semiclassical and mean-field scaling regime. We
    study a class of initial data describing collective particle–hole pair excitations
    on the Fermi ball. Using a rigorous version of approximate bosonization, we prove
    that the many-body evolution can be approximated in Fock space norm by a quasi-free
    bosonic evolution of the collective particle–hole excitations.

  text: Classical models with complex energy landscapes represent a perspective avenue
    for the near-term application of quantum simulators. Until now, many theoretical
    works studied the performance of quantum algorithms for models with a unique ground
    state. However, when the classical problem is in a so-called clustering phase,
    the ground state manifold is highly degenerate. As an example, we consider a 3-XORSAT
    model defined on simple hypergraphs. The degeneracy of classical ground state
    manifold translates into the emergence of an extensive number of Z2 symmetries,
    which remain intact even in the presence of a quantum transverse magnetic field.
    We establish a general duality approach that restricts the quantum problem to
    a given sector of conserved Z2 charges and use it to study how the outcome of
    the quantum adiabatic algorithm depends on the hypergraph geometry. We show that
    the tree hypergraph which corresponds to a classically solvable instance of the
    3-XORSAT problem features a constant gap, whereas the closed hypergraph encounters
    a second-order phase transition with a gap vanishing as a power-law in the problem
    size. The duality developed in this work provides a practical tool for studies
    of quantum models with classically degenerate energy manifold and reveals potential
    connections between glasses and gauge theories.

  text: We derive optimal-order homogenization rates for random nonlinear elliptic
    PDEs with monotone nonlinearity in the uniformly elliptic case. More precisely,
    for a random monotone operator on \mathbb {R}^d with stationary law (that is spatially
    homogeneous statistics) and fast decay of correlations on scales larger than the
    microscale \varepsilon >0, we establish homogenization error estimates of the
    order \varepsilon in case d\geqq 3, and of the order \varepsilon |\log \varepsilon
    |^{1/2} in case d=2. Previous results in nonlinear stochastic homogenization have
    been limited to a small algebraic rate of convergence \varepsilon ^\delta . We
    also establish error estimates for the approximation of the homogenized operator
    by the method of representative volumes of the order (L/\varepsilon )^{-d/2} for
    a representative volume of size L. Our results also hold in the case of systems
    for which a (small-scale) C^{1,\alpha } regularity theory is available.

  text: We study a class of convex-concave saddle-point problems of the form minxmaxy⟨Kx,y⟩+fP(x)−h∗(y)
    where K is a linear operator, fP is the sum of a convex function f with a Lipschitz-continuous
    gradient and the indicator function of a bounded convex polytope P, and h∗ is
    a convex (possibly nonsmooth) function. Such problem arises, for example, as a
    Lagrangian relaxation of various discrete optimization problems. Our main assumptions
    are the existence of an efficient linear minimization oracle (lmo) for fP and
    an efficient proximal map for h∗ which motivate the solution via a blend of proximal
    primal-dual algorithms and Frank-Wolfe algorithms. In case h∗ is the indicator
    function of a linear constraint and function f is quadratic, we show a O(1/n2)
    convergence rate on the dual objective, requiring O(nlogn) calls of lmo. If the
    problem comes from the constrained optimization problem minx∈Rd{fP(x)|Ax−b=0}
    then we additionally get bound O(1/n2) both on the primal gap and on the infeasibility
    gap. In the most general case, we show a O(1/n) convergence rate of the primal-dual
    gap again requiring O(nlogn) calls of lmo. To the best of our knowledge, this
    improves on the known convergence rates for the considered class of saddle-point
    problems. We show applications to labeling problems frequently appearing in machine
    learning and computer vision.

  text: The popularity of permissioned blockchain systems demands BFT SMR protocols
    that are efficient under good network conditions (synchrony) and robust under
    bad network conditions (asynchrony). The state-of-the-art partially synchronous
    BFT SMR protocols provide optimal linear communication cost per decision under
    synchrony and good leaders, but lose liveness under asynchrony. On the other hand,
    the state-of-the-art asynchronous BFT SMR protocols are live even under asynchrony,
    but always pay quadratic cost even under synchrony. In this paper, we propose
    a BFT SMR protocol that achieves the best of both worlds -- optimal linear cost
    per decision under good networks and leaders, optimal quadratic cost per decision
    under bad networks, and remains always live.

  text: 'We present DAG-Rider, the first asynchronous Byzantine Atomic Broadcast protocol
    that achieves optimal resilience, optimal amortized communication complexity,
    and optimal time complexity. DAG-Rider is post-quantum safe and ensures that all
    values proposed by correct processes eventually get delivered. We construct DAG-Rider
    in two layers: In the first layer, processes reliably broadcast their proposals
    and build a structured Directed Acyclic Graph (DAG) of the communication among
    them. In the second layer, processes locally observe their DAGs and totally order
    all proposals with no extra communication.'

  text: Hole gases in planar germanium can have high mobilities in combination with
    strong spin-orbit interaction and electrically tunable g factors, and are therefore
    emerging as a promising platform for creating hybrid superconductor-semiconductor
    devices. A key challenge towards hybrid Ge-based quantum technologies is the design
    of high-quality interfaces and superconducting contacts that are robust against
    magnetic fields. In this work, by combining the assets of aluminum, which provides
    good contact to the Ge, and niobium, which has a significant superconducting gap,
    we demonstrate highly transparent low-disordered JoFETs with relatively large
    ICRN products that are capable of withstanding high magnetic fields. We furthermore
    demonstrate the ability of phase-biasing individual JoFETs, opening up an avenue
    to explore topological superconductivity in planar Ge. The persistence of superconductivity
    in the reported hybrid devices beyond 1.8 T paves the way towards integrating
    spin qubits and proximity-induced superconductivity on the same chip.

  text: 'Enzymatic digestion of the extracellular matrix with chondroitinase-ABC reinstates
    juvenile-like plasticity in the adult cortex as it also disassembles the perineuronal
    nets (PNNs). The disadvantage of the enzyme is that it must be applied intracerebrally
    and it degrades the ECM for several weeks. Here, we provide two minimally invasive
    and transient protocols for microglia-enabled PNN disassembly in mouse cortex:
    repeated treatment with ketamine-xylazine-acepromazine (KXA) anesthesia and 60-Hz
    light entrainment. We also discuss how to analyze PNNs within microglial endosomes-lysosomes.
    For complete details on the use and execution of this protocol, please refer to
    Venturino et al. (2021).'

  text: Genetic adaptation and phenotypic plasticity facilitate the migration into
    new habitats and enable organisms to cope with a rapidly changing environment.
    In contrast to genetic adaptation that spans multiple generations as an evolutionary
    process, phenotypic plasticity allows acclimation within the life-time of an organism.
    Genetic adaptation and phenotypic plasticity are usually studied in isolation,
    however, only by including their interactive impact, we can understand acclimation
    and adaptation in nature. We aimed to explore the contribution of adaptation and
    plasticity in coping with an abiotic (salinity) and a biotic (Vibrio bacteria)
    stressor using six different populations of the broad-nosed pipefish Syngnathus
    typhle that originated from either high [14–17 Practical Salinity Unit (PSU)]
    or low (7–11 PSU) saline environments along the German coastline of the Baltic
    Sea. We exposed wild caught animals, to either high (15 PSU) or low (7 PSU) salinity,
    representing native and novel salinity conditions and allowed animals to mate.
    After male pregnancy, offspring was split and each half was exposed to one of
    the two salinities and infected with Vibrio alginolyticus bacteria that were evolved
    at either of the two salinities in a fully reciprocal design. We investigated
    life-history traits of fathers and expression of 47 target genes in mothers and
    offspring. Pregnant males originating from high salinity exposed to low salinity
    were highly susceptible to opportunistic fungi infections resulting in decreased
    offspring size and number. In contrast, no signs of fungal infection were identified
    in fathers originating from low saline conditions suggesting that genetic adaptation
    has the potential to overcome the challenges encountered at low salinity. Offspring
    from parents with low saline origin survived better at low salinity suggesting
    genetic adaptation to low salinity. In addition, gene expression analyses of juveniles
    indicated patterns of local adaptation, trans-generational plasticity and developmental
    plasticity. In conclusion, our study suggests that pipefish are locally adapted
    to the low salinity in their environment, however, they are retaining phenotypic
    plasticity, which allows them to also cope with ancestral salinity levels and
    prevailing pathogens.

  text: 'For animals to survive until reproduction, it is crucial that juveniles successfully
    detect potential predators and respond with appropriate behavior. The recognition
    of cues originating from predators can be innate or learned. Cues of various modalities
    might be used alone or in multi-modal combinations to detect and distinguish predators
    but studies investigating multi-modal integration in predator avoidance are scarce.
    Here, we used wild, naive tadpoles of the Neotropical poison frog Allobates femoralis
    ( Boulenger, 1884) to test their reaction to cues with two modalities from two
    different sympatrically occurring potential predators: heterospecific predatory
    Dendrobates tinctorius tadpoles and dragonfly larvae. We presented A. femoralis
    tadpoles with olfactory or visual cues, or a combination of the two, and compared
    their reaction to a water control in a between-individual design. In our trials,
    A. femoralis tadpoles reacted to multi-modal stimuli (a combination of visual
    and chemical information) originating from dragonfly larvae with avoidance but
    showed no reaction to uni-modal cues or cues from heterospecific tadpoles. In
    addition, visual cues from conspecifics increased swimming activity while cues
    from predators had no effect on tadpole activity. Our results show that A. femoralis
    tadpoles can innately recognize some predators and probably need both visual and
    chemical information to effectively avoid them. This is the first study looking
    at anti-predator behavior in poison frog tadpoles. We discuss how parental care
    might influence the expression of predator avoidance responses in tadpoles.'

  text: How tissues acquire complex shapes is a fundamental question in biology and
    regenerative medicine. Zebrafish semicircular canals form from invaginations in
    the otic epithelium (buds) that extend and fuse to form the hubs of each canal.
    We find that conventional actomyosin-driven behaviors are not required. Instead,
    local secretion of hyaluronan, made by the enzymes uridine 5′-diphosphate dehydrogenase
    (ugdh) and hyaluronan synthase 3 (has3), drives canal morphogenesis. Charged hyaluronate
    polymers osmotically swell with water and generate isotropic extracellular pressure
    to deform the overlying epithelium into buds. The mechanical anisotropy needed
    to shape buds into tubes is conferred by a polarized distribution of actomyosin
    and E-cadherin-rich membrane tethers, which we term cytocinches. Most work on
    tissue morphogenesis ascribes actomyosin contractility as the driving force, while
    the extracellular matrix shapes tissues through differential stiffness. Our work
    inverts this expectation. Hyaluronate pressure shaped by anisotropic tissue stiffness
    may be a widespread mechanism for powering morphological change in organogenesis
    and tissue engineering.

  text: 'The understanding of material appearance perception is a complex problem
    due to interactions between material reflectance, surface geometry, and illumination.
    Recently, Serrano et al. collected the largest dataset to date with subjective
    ratings of material appearance attributes, including glossiness, metallicness,
    sharpness and contrast of reflections. In this work, we make use of their dataset
    to investigate for the first time the impact of the interactions between illumination,
    geometry, and eight different material categories in perceived appearance attributes.
    After an initial analysis, we select for further analysis the four material categories
    that cover the largest range for all perceptual attributes: fabric, plastic, ceramic,
    and metal. Using a cumulative link mixed model (CLMM) for robust regression, we
    discover interactions between these material categories and four representative
    illuminations and object geometries. We believe that our findings contribute to
    expanding the knowledge on material appearance perception and can be useful for
    many applications, such as scene design, where any particular material in a given
    shape can be aligned with dominant classes of illumination, so that a desired
    strength of appearance attributes can be achieved.'

  text: The choice of the boundary conditions in mechanical problems has to reflect
    the interaction of the considered material with the surface. Still the assumption
    of the no-slip condition is preferred in order to avoid boundary terms in the
    analysis and slipping effects are usually overlooked. Besides the “static slip
    models”, there are phenomena that are not accurately described by them, e.g. at
    the moment when the slip changes rapidly, the wall shear stress and the slip can
    exhibit a sudden overshoot and subsequent relaxation. When these effects become
    significant, the so-called dynamic slip phenomenon occurs. We develop a mathematical
    analysis of Navier–Stokes-like problems with a dynamic slip boundary condition,
    which requires a proper generalization of the Gelfand triplet and the corresponding
    function space setting.

  text: 'We consider a totally asymmetric simple exclusion process (TASEP) consisting
    of particles on a lattice that require binding by a "token" to move. Using a combination
    of theory and simulations, we address the following questions: (i) How token binding
    kinetics affects the current-density relation; (ii) How the current-density relation
    depends on the scarcity of tokens; (iii) How tokens propagate the effects of the
    locally-imposed disorder (such a slow site) over the entire lattice; (iv) How
    a shared pool of tokens couples concurrent TASEPs running on multiple lattices;
    (v) How our results translate to TASEPs with open boundaries that exchange particles
    with the reservoir. Since real particle motion (including in systems that inspired
    the standard TASEP model, e.g., protein synthesis or movement of molecular motors)
    is often catalyzed, regulated, actuated, or otherwise mediated, the token-driven
    TASEP dynamics analyzed in this paper should allow for a better understanding
    of real systems and enable a closer match between TASEP theory and experimental
    observations.'

  text: Recently it was shown that anyons on the two-sphere naturally arise from a
    system of molecular impurities exchanging angular momentum with a many-particle
    bath (Phys. Rev. Lett. 126, 015301 (2021)). Here we further advance this approach
    and rigorously demonstrate that in the experimentally realized regime the lowest
    spectrum of two linear molecules immersed in superfluid helium corresponds to
    the spectrum of two anyons on the sphere. We develop the formalism within the
    framework of the recently experimentally observed angulon quasiparticle

  text: A facile approach for developing an interfacial solar evaporator by heat localization
    of solar-thermal energy conversion at water-air liquid composed by in-situ polymerization
    of Fe2O3 nanoparticles (Fe2O3@PPy) deposited over a facial sponge is proposed.
    The demonstrated system consists of a floating solar receiver having a vertically
    cross-linked microchannel for wicking up saline water. The in situ polymerized
    Fe2O3@PPy interfacial layer promotes diffuse reflection and its rough black surface
    allows Omni-directional solar absorption (94%) and facilitates efficient thermal
    localization at the water/air interface and offers a defect-rich surface to promote
    heat localization (41.9 °C) and excellent thermal management due to cellulosic
    content. The self-floating composite foam reveals continuous vapors generation
    at a rate of 1.52 kg m−2 h−1 under one 1 kW m−2 and profound evaporating efficiency
    (95%) without heat losses that dissipates in its surroundings. Indeed, long-term
    evaporation experiments reveal the negligible disparity in continuous evaporation
    rate (33.84 kg m−2/8.3 h) receiving two sun solar intensity, and ensures the stability
    of the device under intense seawater conditions synchronized with excellent salt
    rejection potential. More importantly, Raman spectroscopy investigation validates
    the orange dye rejection via Fe2O3@PPy solar evaporator. The combined advantages
    of high efficiency, self-floating capability, multimedia rejection, low cost,
    and this configuration are promising for producing large-scale solar steam generating
    systems appropriate for commercial clean water yield due to their scalable fabrication.

  text: 'We study the problem of estimating a rank-$1$ signal in the presence of rotationally
    invariant noise-a class of perturbations more general than Gaussian noise. Principal
    Component Analysis (PCA) provides a natural estimator, and sharp results on its
    performance have been obtained in the high-dimensional regime. Recently, an Approximate
    Message Passing (AMP) algorithm has been proposed as an alternative estimator
    with the potential to improve the accuracy of PCA. However, the existing analysis
    of AMP requires an initialization that is both correlated with the signal and
    independent of the noise, which is often unrealistic in practice. In this work,
    we combine the two methods, and propose to initialize AMP with PCA. Our main result
    is a rigorous asymptotic characterization of the performance of this estimator.
    Both the AMP algorithm and its analysis differ from those previously derived in
    the Gaussian setting: at every iteration, our AMP algorithm requires a specific
    term to account for PCA initialization, while in the Gaussian case, PCA initialization
    affects only the first iteration of AMP. The proof is based on a two-phase artificial
    AMP that first approximates the PCA estimator and then mimics the true AMP. Our
    numerical simulations show an excellent agreement between AMP results and theoretical
    predictions, and suggest an interesting open direction on achieving Bayes-optimal
    performance.'

  text: 'The question of how and why the phenomenon of mode connectivity occurs in
    training deep neural networks has gained remarkable attention in the research
    community. From a theoretical perspective, two possible explanations have been
    proposed: (i) the loss function has connected sublevel sets, and (ii) the solutions
    found by stochastic gradient descent are dropout stable. While these explanations
    provide insights into the phenomenon, their assumptions are not always satisfied
    in practice. In particular, the first approach requires the network to have one
    layer with order of N neurons (N being the number of training samples), while
    the second one requires the loss to be almost invariant after removing half of
    the neurons at each layer (up to some rescaling of the remaining ones). In this
    work, we improve both conditions by exploiting the quality of the features at
    every intermediate layer together with a milder over-parameterization condition.
    More specifically, we show that: (i) under generic assumptions on the features
    of intermediate layers, it suffices that the last two hidden layers have order
    of N−−√ neurons, and (ii) if subsets of features at each layer are linearly separable,
    then no over-parameterization is needed to show the connectivity. Our experiments
    confirm that the proposed condition ensures the connectivity of solutions found
    by stochastic gradient descent, even in settings where the previous requirements
    do not hold.'

  text: 'A recent line of work has analyzed the theoretical properties of deep neural
    networks via the Neural Tangent Kernel (NTK). In particular, the smallest eigenvalue
    of the NTK has been related to the memorization capacity, the global convergence
    of gradient descent algorithms and the generalization of deep nets. However, existing
    results either provide bounds in the two-layer setting or assume that the spectrum
    of the NTK matrices is bounded away from 0 for multi-layer networks. In this paper,
    we provide tight bounds on the smallest eigenvalue of NTK matrices for deep ReLU
    nets, both in the limiting case of infinite widths and for finite widths. In the
    finite-width setting, the network architectures we consider are fairly general:
    we require the existence of a wide layer with roughly order of $N$ neurons, $N$
    being the number of data samples; and the scaling of the remaining layer widths
    is arbitrary (up to logarithmic factors). To obtain our results, we analyze various
    quantities of independent interest: we give lower bounds on the smallest singular
    value of hidden feature matrices, and upper bounds on the Lipschitz constant of
    input-output feature maps.'
