  text: We provide a definition of the effective mass for the classical polaron described
    by the Landau-Pekar equations. It is based on a novel variational principle, minimizing
    the energy functional over states with given (initial) velocity. The resulting
    formula for the polaron's effective mass agrees with the prediction by Landau
    and Pekar.

  text: 'This paper establishes new connections between many-body quantum systems,
    One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport
    (OT), by interpreting the problem of computing the ground-state energy of a finite
    dimensional composite quantum system at positive temperature as a non-commutative
    entropy regularized Optimal Transport problem. We develop a new approach to fully
    characterize the dual-primal solutions in such non-commutative setting. The mathematical
    formalism is particularly relevant in quantum chemistry: numerical realizations
    of the many-electron ground state energy can be computed via a non-commutative
    version of Sinkhorn algorithm. Our approach allows to prove convergence and robustness
    of this algorithm, which, to our best knowledge, were unknown even in the two
    marginal case. Our methods are based on careful a priori estimates in the dual
    problem, which we believe to be of independent interest. Finally, the above results
    are extended in 1RDMFT setting, where bosonic or fermionic symmetry conditions
    are enforced on the problem.'

  text: Astrocytes extensively infiltrate the neuropil to regulate critical aspects
    of synaptic development and function. This process is regulated by transcellular
    interactions between astrocytes and neurons via cell adhesion molecules. How astrocytes
    coordinate developmental processes among one another to parse out the synaptic
    neuropil and form non-overlapping territories is unknown. Here we identify a molecular
    mechanism regulating astrocyte-astrocyte interactions during development to coordinate
    astrocyte morphogenesis and gap junction coupling. We show that hepaCAM, a disease-linked,
    astrocyte-enriched cell adhesion molecule, regulates astrocyte competition for
    territory and morphological complexity in the developing mouse cortex. Furthermore,
    conditional deletion of Hepacam from developing astrocytes significantly impairs
    gap junction coupling between astrocytes and disrupts the balance between synaptic
    excitation and inhibition. Mutations in HEPACAM cause megalencephalic leukoencephalopathy
    with subcortical cysts in humans. Therefore, our findings suggest that disruption
    of astrocyte self-organization mechanisms could be an underlying cause of neural
    pathology.

  text: The quantum bits (qubits) on which superconducting quantum computers are based
    have energy scales corresponding to photons with GHz frequencies. The energy of
    photons in the gigahertz domain is too low to allow transmission through the noisy
    room-temperature environment, where the signal would be lost in thermal noise.
    Optical photons, on the other hand, have much higher energies, and signals can
    be detected using highly efficient single-photon detectors. Transduction from
    microwave to optical frequencies is therefore a potential enabling technology
    for quantum devices. However, in such a device the optical pump can be a source
    of thermal noise and thus degrade the fidelity; the similarity of input microwave
    state to the output optical state. In order to investigate the magnitude of this
    effect we model the sub-Kelvin thermal behavior of an electro-optic transducer
    based on a lithium niobate whispering gallery mode resonator. We find that there
    is an optimum power level for a continuous pump, whilst pulsed operation of the
    pump increases the fidelity of the conversion.

  text: "Aims: Mass antigen testing programs have been challenged because of an alleged
    insufficient specificity, leading to a large number of false positives. The objective
    of this study is to derive a lower bound of the specificity of the SD Biosensor
    Standard Q Ag-Test in large scale practical use.\r\nMethods: Based on county data
    from the nationwide tests for SARS-CoV-2 in Slovakia between 31.10.–1.11. 2020
    we calculate a lower confidence bound for the specificity. As positive test results
    were not systematically verified by PCR tests, we base the lower bound on a worst
    case assumption, assuming all positives to be false positives.\r\nResults: 3,625,332
    persons from 79 counties were tested. The lowest positivity rate was observed
    in the county of Rožňava where 100 out of 34307 (0.29%) tests were positive. This
    implies a test specificity of at least 99.6% (97.5% one-sided lower confidence
    bound, adjusted for multiplicity).\r\nConclusion: The obtained lower bound suggests
    a higher specificity compared to earlier studies in spite of the underlying worst
    case assumption and the application in a mass testing setting. The actual specificity
    is expected to exceed 99.6% if the prevalence in the respective regions was non-negligible
    at the time of testing. To our knowledge, this estimate constitutes the first
    bound obtained from large scale practical use of an antigen test."

  text: Elastic bending of initially flat slender elements allows the realization
    and economic fabrication of intriguing curved shapes. In this work, we derive
    an intuitive but rigorous geometric characterization of the design space of plane
    elastic rods with variable stiffness. It enables designers to determine which
    shapes are physically viable with active bending by visual inspection alone. Building
    on these insights, we propose a method for efficiently designing the geometry
    of a flat elastic rod that realizes a target equilibrium curve, which only requires
    solving a linear program. We implement this method in an interactive computational
    design tool that gives feedback about the feasibility of a design, and computes
    the geometry of the structural elements necessary to realize it within an instant.
    The tool also offers an iterative optimization routine that improves the fabricability
    of a model while modifying it as little as possible. In addition, we use our geometric
    characterization to derive an algorithm for analyzing and recovering the stability
    of elastic curves that would otherwise snap out of their unstable equilibrium
    shapes by buckling. We show the efficacy of our approach by designing and manufacturing
    several physical models that are assembled from flat elements.

  text: Triangle mesh-based simulations are able to produce satisfying animations
    of knitted and woven cloth; however, they lack the rich geometric detail of yarn-level
    simulations. Naive texturing approaches do not consider yarn-level physics, while
    full yarn-level simulations may become prohibitively expensive for large garments.
    We propose a method to animate yarn-level cloth geometry on top of an underlying
    deforming mesh in a mechanics-aware fashion. Using triangle strains to interpolate
    precomputed yarn geometry, we are able to reproduce effects such as knit loops
    tightening under stretching. In combination with precomputed mesh animation or
    real-time mesh simulation, our method is able to animate yarn-level cloth in real-time
    at large scales.

  text: Photorealistic editing of head portraits is a challenging task as humans are
    very sensitive to inconsistencies in faces. We present an approach for high-quality
    intuitive editing of the camera viewpoint and scene illumination (parameterised
    with an environment map) in a portrait image. This requires our method to capture
    and control the full reflectance field of the person in the image. Most editing
    approaches rely on supervised learning using training data captured with setups
    such as light and camera stages. Such datasets are expensive to acquire, not readily
    available and do not capture all the rich variations of in-the-wild portrait images.
    In addition, most supervised approaches only focus on relighting, and do not allow
    camera viewpoint editing. Thus, they only capture and control a subset of the
    reflectance field. Recently, portrait editing has been demonstrated by operating
    in the generative model space of StyleGAN. While such approaches do not require
    direct supervision, there is a significant loss of quality when compared to the
    supervised approaches. In this paper, we present a method which learns from limited
    supervised training data. The training images only include people in a fixed neutral
    expression with eyes closed, without much hair or background variations. Each
    person is captured under 150 one-light-at-a-time conditions and under 8 camera
    poses. Instead of training directly in the image space, we design a supervised
    problem which learns transformations in the latent space of StyleGAN. This combines
    the best of supervised learning and generative adversarial modeling. We show that
    the StyleGAN prior allows for generalisation to different expressions, hairstyles
    and backgrounds. This produces high-quality photorealistic results for in-the-wild
    images and significantly outperforms existing methods. Our approach can edit the
    illumination and pose simultaneously, and runs at interactive rates.

  text: Material appearance hinges on material reflectance properties but also surface
    geometry and illumination. The unlimited number of potential combinations between
    these factors makes understanding and predicting material appearance a very challenging
    task. In this work, we collect a large-scale dataset of perceptual ratings of
    appearance attributes with more than 215,680 responses for 42,120 distinct combinations
    of material, shape, and illumination. The goal of this dataset is twofold. First,
    we analyze for the first time the effects of illumination and geometry in material
    perception across such a large collection of varied appearances. We connect our
    findings to those of the literature, discussing how previous knowledge generalizes
    across very diverse materials, shapes, and illuminations. Second, we use the collected
    dataset to train a deep learning architecture for predicting perceptual attributes
    that correlate with human judgments. We demonstrate the consistent and robust
    behavior of our predictor in various challenging scenarios, which, for the first
    time, enables estimating perceived material attributes from general 2D images.
    Since our predictor relies on the final appearance in an image, it can compare
    appearance properties across different geometries and illumination conditions.
    Finally, we demonstrate several applications that use our predictor, including
    appearance reproduction using 3D printing, BRDF editing by integrating our predictor
    in a differentiable renderer, illumination design, or material recommendations
    for scene design.

  text: Heart rate variability (hrv) is a physiological phenomenon of the variation
    in the length of the time interval between consecutive heartbeats. In many cases
    it could be an indicator of the development of pathological states. The classical
    approach to the analysis of hrv includes time domain methods and frequency domain
    methods. However, attempts are still being made to define new and more effective
    hrv assessment tools. Persistent homology is a novel data analysis tool developed
    in the recent decades that is rooted at algebraic topology. The Topological Data
    Analysis (TDA) approach focuses on examining the shape of the data in terms of
    connectedness and holes, and has recently proved to be very effective in various
    fields of research. In this paper we propose the use of persistent homology to
    the hrv analysis. We recall selected topological descriptors used in the literature
    and we introduce some new topological descriptors that reflect the specificity
    of hrv, and we discuss their relation to the standard hrv measures. In particular,
    we show that this novel approach provides a collection of indices that might be
    at least as useful as the classical parameters in differentiating between series
    of beat-to-beat intervals (RR-intervals) in healthy subjects and patients suffering
    from a stroke episode.

  text: Attachment of adhesive molecules on cell culture surfaces to restrict cell
    adhesion to defined areas and shapes has been vital for the progress of in vitro
    research. In currently existing patterning methods, a combination of pattern properties
    such as stability, precision, specificity, high-throughput outcome, and spatiotemporal
    control is highly desirable but challenging to achieve. Here, we introduce a versatile
    and high-throughput covalent photoimmobilization technique, comprising a light-dose-dependent
    patterning step and a subsequent functionalization of the pattern via click chemistry.
    This two-step process is feasible on arbitrary surfaces and allows for generation
    of sustainable patterns and gradients. The method is validated in different biological
    systems by patterning adhesive ligands on cell-repellent surfaces, thereby constraining
    the growth and migration of cells to the designated areas. We then implement a
    sequential photopatterning approach by adding a second switchable patterning step,
    allowing for spatiotemporal control over two distinct surface patterns. As a proof
    of concept, we reconstruct the dynamics of the tip/stalk cell switch during angiogenesis.
    Our results show that the spatiotemporal control provided by our “sequential photopatterning”
    system is essential for mimicking dynamic biological processes and that our innovative
    approach has great potential for further applications in cell science.

  text: "Approximate agreement is one of the few variants of consensus that can be
    solved in a wait-free manner in asynchronous systems where processes communicate
    by reading and writing to shared memory. In this work, we consider a natural generalisation
    of approximate agreement on arbitrary undirected connected graphs. Each process
    is given a vertex of the graph as input and, if non-faulty, must output a vertex
    such that\r\nall the outputs are within distance 1 of one another, and\r\n\r\neach
    output value lies on a shortest path between two input values.\r\n\r\nFrom prior
    work, it is known that there is no wait-free algorithm among   \U0001D45B≥3  processes
    for this problem on any cycle of length   \U0001D450≥4 , by reduction from 2-set
    agreement (Castañeda et al. 2018).\r\n\r\nIn this work, we investigate the solvability
    and complexity of this task on general graphs. We give a new, direct proof of
    the impossibility of approximate agreement on cycles of length   \U0001D450≥4
    , via a generalisation of Sperner’s Lemma to convex polygons. We also extend the
    reduction from 2-set agreement to a larger class of graphs, showing that approximate
    agreement on these graphs is unsolvable. On the positive side, we present a wait-free
    algorithm for a class of graphs that properly contains the class of chordal graphs."

  text: We define a new compact coordinate system in which each integer triplet addresses
    a voxel in the BCC grid, and we investigate some of its properties. We propose
    a characterization of 3D discrete analytical planes with their topological features
    (in the Cartesian and in the new coordinate system) such as the interrelation
    between the thickness of the plane and the separability constraint we aim to obtain.

  text: "The dual attack has long been considered a relevant attack on lattice-based
    cryptographic schemes relying on the hardness of learning with errors (LWE) and
    its structured variants. As solving LWE corresponds to finding a nearest point
    on a lattice, one may naturally wonder how efficient this dual approach is for
    solving more general closest vector problems, such as the classical closest vector
    problem (CVP), the variants bounded distance decoding (BDD) and approximate CVP,
    and preprocessing versions of these problems. While primal, sieving-based solutions
    to these problems (with preprocessing) were recently studied in a series of works
    on approximate Voronoi cells [Laa16b, DLdW19, Laa20, DLvW20], for the dual attack
    no such overview exists, especially for problems with preprocessing. With one
    of the take-away messages of the approximate Voronoi cell line of work being that
    primal attacks work well for approximate CVP(P) but scale poorly for BDD(P), one
    may further wonder if the dual attack suffers the same drawbacks, or if it is
    perhaps a better solution when trying to solve BDD(P).\r\n\r\nIn this work we
    provide an overview of cost estimates for dual algorithms for solving these “classical”
    closest lattice vector problems. Heuristically we expect to solve the search version
    of average-case CVPP in time and space   20.293\U0001D451+\U0001D45C(\U0001D451)
    \ in the single-target model. The distinguishing version of average-case CVPP,
    where we wish to distinguish between random targets and targets planted at distance
    (say)   0.99⋅\U0001D454\U0001D451  from the lattice, has the same complexity in
    the single-target model, but can be solved in time and space   20.195\U0001D451+\U0001D45C(\U0001D451)
    \ in the multi-target setting, when given a large number of targets from either
    target distribution. This suggests an inequivalence between distinguishing and
    searching, as we do not expect a similar improvement in the multi-target setting
    to hold for search-CVPP. We analyze three slightly different decoders, both for
    distinguishing and searching, and experimentally obtain concrete cost estimates
    for the dual attack in dimensions 50 to 80, which confirm our heuristic assumptions,
    and show that the hidden order terms in the asymptotic estimates are quite small.\r\n\r\nOur
    main take-away message is that the dual attack appears to mirror the approximate
    Voronoi cell line of work – whereas using approximate Voronoi cells works well
    for approximate CVP(P) but scales poorly for BDD(P), the dual approach scales
    well for BDD(P) instances but performs poorly on approximate CVP(P)."

  text: "Automated contract tracing aims at supporting manual contact tracing during
    pandemics by alerting users of encounters with infected people. There are currently
    many proposals for protocols (like the “decentralized” DP-3T and PACT or the “centralized”
    ROBERT and DESIRE) to be run on mobile phones, where the basic idea is to regularly
    broadcast (using low energy Bluetooth) some values, and at the same time store
    (a function of) incoming messages broadcasted by users in their proximity. In
    the existing proposals one can trigger false positives on a massive scale by an
    “inverse-Sybil” attack, where a large number of devices (malicious users or hacked
    phones) pretend to be the same user, such that later, just a single person needs
    to be diagnosed (and allowed to upload) to trigger an alert for all users who
    were in proximity to any of this large group of devices.\r\n\r\nWe propose the
    first protocols that do not succumb to such attacks assuming the devices involved
    in the attack do not constantly communicate, which we observe is a necessary assumption.
    The high level idea of the protocols is to derive the values to be broadcasted
    by a hash chain, so that two (or more) devices who want to launch an inverse-Sybil
    attack will not be able to connect their respective chains and thus only one of
    them will be able to upload. Our protocols also achieve security against replay,
    belated replay, and one of them even against relay attacks."

  text: 'The Nearest neighbour search (NNS) is a fundamental problem in many application
    domains dealing with multidimensional data. In a concurrent setting, where dynamic
    modifications are allowed, a linearizable implementation of the NNS is highly
    desirable.This paper introduces the LockFree-kD-tree (LFkD-tree ): a lock-free
    concurrent kD-tree, which implements an abstract data type (ADT) that provides
    the operations Add, Remove, Contains, and NNS. Our implementation is linearizable.
    The operations in the LFkD-tree use single-word read and compare-and-swap (Image
    1 ) atomic primitives, which are readily supported on available multi-core processors.
    We experimentally evaluate the LFkD-tree using several benchmarks comprising real-world
    and synthetic datasets. The experiments show that the presented design is scalable
    and achieves significant speed-up compared to the implementations of an existing
    sequential kD-tree and a recently proposed multidimensional indexing structure,
    PH-tree.'

  text: Amplitude demodulation is a classical operation used in signal processing.
    For a long time, its effective applications in practice have been limited to narrowband
    signals. In this work, we generalize amplitude demodulation to wideband signals.
    We pose demodulation as a recovery problem of an oversampled corrupted signal
    and introduce special iterative schemes belonging to the family of alternating
    projection algorithms to solve it. Sensibly chosen structural assumptions on the
    demodulation outputs allow us to reveal the high inferential accuracy of the method
    over a rich set of relevant signals. This new approach surpasses current state-of-the-art
    demodulation techniques apt to wideband signals in computational efficiency by
    up to many orders of magnitude with no sacrifice in quality. Such performance
    opens the door for applications of the amplitude demodulation procedure in new
    contexts. In particular, the new method makes online and large-scale offline data
    processing feasible, including the calculation of modulator-carrier pairs in higher
    dimensions and poor sampling conditions, independent of the signal bandwidth.
    We illustrate the utility and specifics of applications of the new method in practice
    by using natural speech and synthetic signals.

  text: In 2020, many in-person scientific events were canceled due to the COVID-19
    pandemic, creating a vacuum in networking and knowledge exchange between scientists.
    To fill this void in scientific communication, a group of early career nanocrystal
    enthusiasts launched the virtual seminar series, News in Nanocrystals, in the
    summer of 2020. By the end of the year, the series had attracted over 850 participants
    from 46 countries. In this Nano Focus, we describe the process of organizing the
    News in Nanocrystals seminar series; discuss its growth, emphasizing what the
    organizers have learned in terms of diversity and accessibility; and provide an
    outlook for the next steps and future opportunities. This summary and analysis
    of experiences and learned lessons are intended to inform the broader scientific
    community, especially those who are looking for avenues to continue fostering
    discussion and scientific engagement virtually, both during the pandemic and after.

  text: Myocardial regeneration is restricted to early postnatal life, when mammalian
    cardiomyocytes still retain the ability to proliferate. The molecular cues that
    induce cell cycle arrest of neonatal cardiomyocytes towards terminally differentiated
    adult heart muscle cells remain obscure. Here we report that the miR-106b~25 cluster
    is higher expressed in the early postnatal myocardium and decreases in expression
    towards adulthood, especially under conditions of overload, and orchestrates the
    transition of cardiomyocyte hyperplasia towards cell cycle arrest and hypertrophy
    by virtue of its targetome. In line, gene delivery of miR-106b~25 to the mouse
    heart provokes cardiomyocyte proliferation by targeting a network of negative
    cell cycle regulators including E2f5, Cdkn1c, Ccne1 and Wee1. Conversely, gene-targeted
    miR-106b~25 null mice display spontaneous hypertrophic remodeling and exaggerated
    remodeling to overload by derepression of the prohypertrophic transcription factors
    Hand2 and Mef2d. Taking advantage of the regulatory function of miR-106b~25 on
    cardiomyocyte hyperplasia and hypertrophy, viral gene delivery of miR-106b~25
    provokes nearly complete regeneration of the adult myocardium after ischemic injury.
    Our data demonstrate that exploitation of conserved molecular programs can enhance
    the regenerative capacity of the injured heart.

  text: 'Parent-of-origin–dependent gene expression in mammals and flowering plants
    results from differing chromatin imprints (genomic imprinting) between maternally
    and paternally inherited alleles. Imprinted gene expression in the endosperm of
    seeds is associated with localized hypomethylation of maternally but not paternally
    inherited DNA, with certain small RNAs also displaying parent-of-origin–specific
    expression. To understand the evolution of imprinting mechanisms in Oryza sativa
    (rice), we analyzed imprinting divergence among four cultivars that span both
    japonica and indica subspecies: Nipponbare, Kitaake, 93-11, and IR64. Most imprinted
    genes are imprinted across cultivars and enriched for functions in chromatin and
    transcriptional regulation, development, and signaling. However, 4 to 11% of imprinted
    genes display divergent imprinting. Analyses of DNA methylation and small RNAs
    revealed that endosperm-specific 24-nt small RNA–producing loci show weak RNA-directed
    DNA methylation, frequently overlap genes, and are imprinted four times more often
    than genes. However, imprinting divergence most often correlated with local DNA
    methylation epimutations (9 of 17 assessable loci), which were largely stable
    within subspecies. Small insertion/deletion events and transposable element insertions
    accompanied 4 of the 9 locally epimutated loci and associated with imprinting
    divergence at another 4 of the remaining 8 loci. Correlating epigenetic and genetic
    variation occurred at key regulatory regions—the promoter and transcription start
    site of maternally biased genes, and the promoter and gene body of paternally
    biased genes. Our results reinforce models for the role of maternal-specific DNA
    hypomethylation in imprinting of both maternally and paternally biased genes,
    and highlight the role of transposition and epimutation in rice imprinting evolution.'
