  text: In this work, we apply the dynamical systems analysis of Hanrot et al. (CRYPTO’11)
    to a class of lattice block reduction algorithms that includes (natural variants
    of) slide reduction and block-Rankin reduction. This implies sharper bounds on
    the polynomial running times (in the query model) for these algorithms and opens
    the door to faster practical variants of slide reduction. We give heuristic arguments
    showing that such variants can indeed speed up slide reduction significantly in
    practice. This is confirmed by experimental evidence, which also shows that our
    variants are competitive with state-of-the-art reduction algorithms.

  text: "Turbulence in the flow of fluid through a pipe can be suppressed by buoyancy
    forces. As the suppression of turbulence leads to severe heat transfer deterioration,
    this is an important and undesirable phenomenon in both heating and cooling applications.
    Vertical flow is often considered, as the axial buoyancy force can help drive
    the flow. With heating measured by the buoyancy parameter \U0001D436, our direct
    numerical simulations show that shear-driven turbulence may either be completely
    laminarised or it transitions to a relatively quiescent convection-driven state.
    Buoyancy forces cause a flattening of the base flow profile, which in isothermal
    pipe flow has recently been linked to complete suppression of turbulence (Kühnen
    et al., Nat. Phys., vol. 14, 2018, pp. 386–390), and the flattened laminar base
    profile has enhanced nonlinear stability (Marensi et al., J. Fluid Mech., vol.
    863, 2019, pp. 50–875). In agreement with these findings, the nonlinear lower-branch
    travelling-wave solution analysed here, which is believed to mediate transition
    to turbulence in isothermal pipe flow, is shown to be suppressed by buoyancy.
    A linear instability of the laminar base flow is responsible for the appearance
    of the relatively quiescent convection driven state for \U0001D436≳4 across the
    range of Reynolds numbers considered. In the suppression of turbulence, however,
    i.e. in the transition from turbulence, we find clearer association with the analysis
    of He et al. (J. Fluid Mech., vol. 809, 2016, pp. 31–71) than with the above dynamical
    systems approach, which describes better the transition to turbulence. The laminarisation
    criterion He et al. propose, based on an apparent Reynolds number of the flow
    as measured by its driving pressure gradient, is found to capture the critical
    \U0001D436=\U0001D436\U0001D450\U0001D45F(\U0001D445\U0001D452) above which the
    flow will be laminarised or switch to the convection-driven type. Our analysis
    suggests that it is the weakened rolls, rather than the streaks, which appear
    to be critical for laminarisation."

  text: "Motivated by the successful application of geometry to proving the Harary--Hill
    conjecture for “pseudolinear” drawings of $K_n$, we introduce “pseudospherical”
    drawings of graphs. A spherical drawing of a graph $G$ is a drawing in the unit
    sphere $\\mathbb{S}^2$ in which the vertices of $G$ are represented as points---no
    three on a great circle---and the edges of $G$ are shortest-arcs in $\\mathbb{S}^2$
    connecting pairs of vertices. Such a drawing has three properties: (1) every edge
    $e$ is contained in a simple closed curve $\\gamma_e$ such that the only vertices
    in $\\gamma_e$ are the ends of $e$; (2) if $e\\ne f$, then $\\gamma_e\\cap\\gamma_f$
    has precisely two crossings; and (3) if $e\\ne f$, then $e$ intersects $\\gamma_f$
    at most once, in either a crossing or an end of $e$. We use properties (1)--(3)
    to define a pseudospherical drawing of $G$. Our main result is that for the complete
    graph, properties (1)--(3) are equivalent to the same three properties but with
    “precisely two crossings” in (2) replaced by “at most two crossings.” The proof
    requires a result in the geometric transversal theory of arrangements of pseudocircles.
    This is proved using the surprising result that the absence of special arcs (coherent
    spirals) in an arrangement of simple closed curves characterizes the fact that
    any two curves in the arrangement have at most two crossings. Our studies provide
    the necessary ideas for exhibiting a drawing of $K_{10}$ that has no extension
    to an arrangement of pseudocircles and a drawing of $K_9$ that does extend to
    an arrangement of pseudocircles, but no such extension has all pairs of pseudocircles
    crossing twice.\r\n"

  text: A key step in understanding the genetic basis of different evolutionary outcomes
    (e.g., adaptation) is to determine the roles played by different mutation types
    (e.g., SNPs, translocations and inversions). To do this we must simultaneously
    consider different mutation types in an evolutionary framework. Here, we propose
    a research framework that directly utilizes the most important characteristics
    of mutations, their population genetic effects, to determine their relative evolutionary
    significance in a given scenario. We review known population genetic effects of
    different mutation types and show how these may be connected to different evolutionary
    outcomes. We provide examples of how to implement this framework and pinpoint
    areas where more data, theory and synthesis are needed. Linking experimental and
    theoretical approaches to examine different mutation types simultaneously is a
    critical step towards understanding their evolutionary significance.

  text: The hexameric AAA-ATPase Drg1 is a key factor in eukaryotic ribosome biogenesis
    and initiates cytoplasmic maturation of the large ribosomal subunit by releasing
    the shuttling maturation factor Rlp24. Drg1 monomers contain two AAA-domains (D1
    and D2) that act in a concerted manner. Rlp24 release is inhibited by the drug
    diazaborine which blocks ATP hydrolysis in D2. The mode of inhibition was unknown.
    Here we show the first cryo-EM structure of Drg1 revealing the inhibitory mechanism.
    Diazaborine forms a covalent bond to the 2′-OH of the nucleotide in D2, explaining
    its specificity for this site. As a consequence, the D2 domain is locked in a
    rigid, inactive state, stalling the whole Drg1 hexamer. Resistance mechanisms
    identified include abolished drug binding and altered positioning of the nucleotide.
    Our results suggest nucleotide-modifying compounds as potential novel inhibitors
    for AAA-ATPases.

  text: The Massively Parallel Computation (MPC) model is an emerging model that distills
    core aspects of distributed and parallel computation, developed as a tool to solve
    combinatorial (typically graph) problems in systems of many machines with limited
    space. Recent work has focused on the regime in which machines have sublinear
    (in n, the number of nodes in the input graph) space, with randomized algorithms
    presented for the fundamental problems of Maximal Matching and Maximal Independent
    Set. However, there have been no prior corresponding deterministic algorithms.
    A major challenge underlying the sublinear space setting is that the local space
    of each machine might be too small to store all edges incident to a single node.
    This poses a considerable obstacle compared to classical models in which each
    node is assumed to know and have easy access to its incident edges. To overcome
    this barrier, we introduce a new graph sparsification technique that deterministically
    computes a low-degree subgraph, with the additional property that solving the
    problem on this subgraph provides significant progress towards solving the problem
    for the original input graph. Using this framework to derandomize the well-known
    algorithm of Luby [SICOMP’86], we obtain O(log Δ + log log n)-round deterministic
    MPC algorithms for solving the problems of Maximal Matching and Maximal Independent
    Set with O(nɛ) space on each machine for any constant ɛ > 0. These algorithms
    also run in O(log Δ) rounds in the closely related model of CONGESTED CLIQUE,
    improving upon the state-of-the-art bound of O(log 2Δ) rounds by Censor-Hillel
    et al. [DISC’17].

  text: We consider the problem ofdistributed mean estimation (DME), in which n machines
    are each given a local d-dimensional vector xv∈Rd, and must cooperate to estimate
    the mean of their inputs μ=1n∑nv=1xv, while minimizing total communication cost.
    DME is a fundamental construct in distributed machine learning, and there has
    been considerable work on variants of this problem, especially in the context
    of distributed variance reduction for stochastic gradients in parallel SGD. Previous
    work typically assumes an upper bound on the norm of the input vectors, and achieves
    an error bound in terms of this norm. However, in many real applications, the
    input vectors are concentrated around the correct output μ, but μ itself has large
    norm. In such cases, previous output error bounds perform poorly. In this paper,
    we show that output error bounds need not depend on input norm. We provide a method
    of quantization which allows distributed mean estimation to be performed with
    solution quality dependent only on the distance between inputs, not on input norm,
    and show an analogous result for distributed variance reduction. The technique
    is based on a new connection with lattice theory. We also provide lower bounds
    showing that the communication to error trade-off of our algorithms is asymptotically
    optimal. As the lattices achieving optimal bounds under l2-norm can be computationally
    impractical, we also present an extension which leverages easy-to-use cubic lattices,
    and is loose only up to a logarithmic factor ind. We show experimentally that
    our method yields practical improvements for common applications, relative to
    prior approaches.

  text: With the wider availability of full-color 3D printers, color-accurate 3D-print
    preparation has received increased attention. A key challenge lies in the inherent
    translucency of commonly used print materials that blurs out details of the color
    texture. Previous work tries to compensate for these scattering effects through
    strategic assignment of colored primary materials to printer voxels. To date,
    the highest-quality approach uses iterative optimization that relies on computationally
    expensive Monte Carlo light transport simulation to predict the surface appearance
    from subsurface scattering within a given print material distribution; that optimization,
    however, takes in the order of days on a single machine. In our work, we dramatically
    speed up the process by replacing the light transport simulation with a data-driven
    approach. Leveraging a deep neural network to predict the scattering within a
    highly heterogeneous medium, our method performs around two orders of magnitude
    faster than Monte Carlo rendering while yielding optimization results of similar
    quality level. The network is based on an established method from atmospheric
    cloud rendering, adapted to our domain and extended by a physically motivated
    weight sharing scheme that substantially reduces the network size. We analyze
    its performance in an end-to-end print preparation pipeline and compare quality
    and runtime to alternative approaches, and demonstrate its generalization to unseen
    geometry and material values. This for the first time enables full heterogenous
    material optimization for 3D-print preparation within time frames in the order
    of the actual printing time.

  text: 'We extend the notion of the minimal volume ellipsoid containing a convex
    body in Rd to the setting of logarithmically concave functions. We consider a
    vast class of logarithmically concave functions whose superlevel sets are concentric
    ellipsoids. For a fixed function from this class, we consider the set of all its
    “affine” positions. For any log-concave function f on Rd, we consider functions
    belonging to this set of “affine” positions, and find the one with the minimal
    integral under the condition that it is pointwise greater than or equal to f.
    We study the properties of existence and uniqueness of the solution to this problem.
    For any s∈[0,+∞), we consider the construction dual to the recently defined John
    s-function (Ivanov and Naszódi in Functional John ellipsoids. arXiv preprint:
    arXiv:2006.09934, 2020). We prove that such a construction determines a unique
    function and call it the Löwner s-function of f. We study the Löwner s-functions
    as s tends to zero and to infinity. Finally, extending the notion of the outer
    volume ratio, we define the outer integral ratio of a log-concave function and
    give an asymptotically tight bound on it.'

  text: 'AMPA receptors (AMPARs) mediate the majority of excitatory transmission in
    the brain and enable the synaptic plasticity that underlies learning1. A diverse
    array of AMPAR signalling complexes are established by receptor auxiliary subunits,
    which associate with the AMPAR in various combinations to modulate trafficking,
    gating and synaptic strength2. However, their mechanisms of action are poorly
    understood. Here we determine cryo-electron microscopy structures of the heteromeric
    GluA1–GluA2 receptor assembled with both TARP-γ8 and CNIH2, the predominant AMPAR
    complex in the forebrain, in both resting and active states. Two TARP-γ8 and two
    CNIH2 subunits insert at distinct sites beneath the ligand-binding domains of
    the receptor, with site-specific lipids shaping each interaction and affecting
    the gating regulation of the AMPARs. Activation of the receptor leads to asymmetry
    between GluA1 and GluA2 along the ion conduction path and an outward expansion
    of the channel triggers counter-rotations of both auxiliary subunit pairs, promoting
    the active-state conformation. In addition, both TARP-γ8 and CNIH2 pivot towards
    the pore exit upon activation, extending their reach for cytoplasmic receptor
    elements. CNIH2 achieves this through its uniquely extended M2 helix, which has
    transformed this endoplasmic reticulum-export factor into a powerful AMPAR modulator
    that is capable of providing hippocampal pyramidal neurons with their integrative
    synaptic properties. '

  text: We report the synthesis and characterization of graphene functionalized with
    iron (Fe3+) oxide (G-Fe3O4) nanohybrids for radio-frequency magnetic hyperthermia
    application. We adopted the wet chemical procedure, using various contents of
    Fe3O4 (magnetite) from 0–100% for making two-dimensional graphene–Fe3O4 nanohybrids.
    The homogeneous dispersal of Fe3O4 nanoparticles decorated on the graphene surface
    combined with their biocompatibility and high thermal conductivity make them an
    excellent material for magnetic hyperthermia. The morphological and magnetic properties
    of the nanohybrids were studied using scanning electron microscopy (SEM) and a
    vibrating sample magnetometer (VSM), respectively. The smart magnetic platforms
    were exposed to an alternating current (AC) magnetic field of 633 kHz and of strength
    9.1 mT for studying their hyperthermic performance. The localized antitumor effects
    were investigated with artificial neural network modeling. A neural net time-series
    model was developed for the assessment of the best nanohybrid composition to serve
    the purpose with an accuracy close to 100%. Six Nonlinear Autoregressive with
    External Input (NARX) models were obtained, one for each of the components. The
    assessment of the accuracy of the predicted results has been done on the basis
    of Mean Squared Error (MSE). The highest Mean Squared Error value was obtained
    for the nanohybrid containing 45% magnetite and 55% graphene (F45G55) in the training
    phase i.e., 0.44703, which is where the model achieved optimal results after 71
    epochs. The F45G55 nanohybrid was found to be the best for hyperthermia applications
    in low dosage with the highest specific absorption rate (SAR) and mean squared
    error values.

  text: We present conductance-matrix measurements in long, three-terminal hybrid
    superconductor-semiconductor nanowires, and compare with theoretical predictions
    of a magnetic-field-driven, topological quantum phase transition. By examining
    the nonlocal conductance, we identify the closure of the excitation gap in the
    bulk of the semiconductor before the emergence of zero-bias peaks, ruling out
    spurious gap-closure signatures from localized states. We observe that after the
    gap closes, nonlocal signals and zero-bias peaks fluctuate strongly at both ends,
    inconsistent with a simple picture of clean topological superconductivity.

  text: As the size and complexity of models and datasets grow, so does the need for
    communication-efficient variants of stochastic gradient descent that can be deployed
    to perform parallel model training. One popular communication-compression method
    for data-parallel SGD is QSGD (Alistarh et al., 2017), which quantizes and encodes
    gradients to reduce communication costs. The baseline variant of QSGD provides
    strong theoretical guarantees, however, for practical purposes, the authors proposed
    a heuristic variant which we call QSGDinf, which demonstrated impressive empirical
    gains for distributed training of large neural networks. In this paper, we build
    on this work to propose a new gradient quantization scheme, and show that it has
    both stronger theoretical guarantees than QSGD, and matches and exceeds the empirical
    performance of the QSGDinf heuristic and of other compression methods.

  text: We prove that every n-vertex tournament G has an acyclic subgraph with chromatic
    number at least n5/9−o(1), while there exists an n-vertex tournament G whose every
    acyclic subgraph has chromatic number at most n3/4+o(1). This establishes in a
    strong form a conjecture of Nassar and Yuster and improves on another result of
    theirs. Our proof combines probabilistic and spectral techniques together with
    some additional ideas. In particular, we prove a lemma showing that every tournament
    with many transitive subtournaments has a large subtournament that is almost transitive.
    This may be of independent interest.

  text: The convex grabbing game is a game where two players, Alice and Bob, alternate
    taking extremal points from the convex hull of a point set on the plane. Rational
    weights are given to the points. The goal of each player is to maximize the total
    weight over all points that they obtain. We restrict the setting to the case of
    binary weights. We show a construction of an arbitrarily large odd-sized point
    set that allows Bob to obtain almost 3/4 of the total weight. This construction
    answers a question asked by Matsumoto, Nakamigawa, and Sakuma in [Graphs and Combinatorics,
    36/1 (2020)]. We also present an arbitrarily large even-sized point set where
    Bob can obtain the entirety of the total weight. Finally, we discuss conjectures
    about optimum moves in the convex grabbing game for both players in general.

  text: 'In mammalian genomes, differentially methylated regions (DMRs) and histone
    marks including trimethylation of histone 3 lysine 27 (H3K27me3) at imprinted
    genes are asymmetrically inherited to control parentally-biased gene expression.
    However, neither parent-of-origin-specific transcription nor imprints have been
    comprehensively mapped at the blastocyst stage of preimplantation development.
    Here, we address this by integrating transcriptomic and epigenomic approaches
    in mouse preimplantation embryos. We find that seventy-one genes exhibit previously
    unreported parent-of-origin-specific expression in blastocysts (nBiX: novel blastocyst-imprinted
    expressed). Uniparental expression of nBiX genes disappears soon after implantation.
    Micro-whole-genome bisulfite sequencing (µWGBS) of individual uniparental blastocysts
    detects 859 DMRs. We further find that 16% of nBiX genes are associated with a
    DMR, whereas most are associated with parentally-biased H3K27me3, suggesting a
    role for Polycomb-mediated imprinting in blastocysts. nBiX genes are clustered:
    five clusters contained at least one published imprinted gene, and five clusters
    exclusively contained nBiX genes. These data suggest that early development undergoes
    a complex program of stage-specific imprinting involving different tiers of regulation.'

  text: "An ordered graph is a graph with a linear ordering on its vertex set. We
    prove that for every positive integer k, there exists a constant ck > 0 such that
    any ordered graph G on n vertices with the property that neither G nor its complement
    contains an induced monotone path of size k, has either a clique or an independent
    set of size at least n^ck . This strengthens a result of Bousquet, Lagoutte, and
    Thomassé, who proved the analogous result for unordered graphs.\r\nA key idea
    of the above paper was to show that any unordered graph on n vertices that does
    not contain an induced path of size k, and whose maximum degree is at most c(k)n
    for some small c(k) > 0, contains two disjoint linear size subsets with no edge
    between them. This approach fails for ordered graphs, because the analogous statement
    is false for k ≥ 3, by a construction of Fox. We provide some further examples
    showing that this statement also fails for ordered graphs avoiding other ordered
    trees."

  text: Mosaic analysis with double markers (MADM) offers one approach to visualize
    and concomitantly manipulate genetically defined cells in mice with single-cell
    resolution. MADM applications include the analysis of lineage, single-cell morphology
    and physiology, genomic imprinting phenotypes, and dissection of cell-autonomous
    gene functions in vivo in health and disease. Yet, MADM can only be applied to
    <25% of all mouse genes on select chromosomes to date. To overcome this limitation,
    we generate transgenic mice with knocked-in MADM cassettes near the centromeres
    of all 19 autosomes and validate their use across organs. With this resource,
    >96% of the entire mouse genome can now be subjected to single-cell genetic mosaic
    analysis. Beyond a proof of principle, we apply our MADM library to systematically
    trace sister chromatid segregation in distinct mitotic cell lineages. We find
    striking chromosome-specific biases in segregation patterns, reflecting a putative
    mechanism for the asymmetric segregation of genetic determinants in somatic stem
    cell division.

  text: Generalizing Lee’s inductive argument for counting the cells of higher order
    Voronoi tessellations in ℝ² to ℝ³, we get precise relations in terms of Morse
    theoretic quantities for piecewise constant functions on planar arrangements.
    Specifically, we prove that for a generic set of n ≥ 5 points in ℝ³, the number
    of regions in the order-k Voronoi tessellation is N_{k-1} - binom(k,2)n + n, for
    1 ≤ k ≤ n-1, in which N_{k-1} is the sum of Euler characteristics of these function’s
    first k-1 sublevel sets. We get similar expressions for the vertices, edges, and
    polygons of the order-k Voronoi tessellation.
