  text: Polar codes are a channel coding scheme for the next generation of wireless
    communications standard (5G). The belief propagation (BP) decoder allows for parallel
    decoding of polar codes, making it suitable for high throughput applications.
    However, the error-correction performance of polar codes under BP decoding is
    far from the requirements of 5G. It has been shown that the error-correction performance
    of BP can be improved if the decoding is performed on multiple permuted factor
    graphs of polar codes. However, a different BP decoding scheduling is required
    for each factor graph permutation which results in the design of a different decoder
    for each permutation. Moreover, the selection of the different factor graph permutations
    is at random, which prevents the decoder to achieve a desirable error correction
    performance with a small number of permutations. In this paper, we first show
    that the permutations on the factor graph can be mapped into suitable permutations
    on the codeword positions. As a result, we can make use of a single decoder for
    all the permutations. In addition, we introduce a method to construct a set of
    predetermined permutations which can provide the correct codeword if the decoding
    fails on the original permutation. We show that for the 5G polar code of length
    1024, the error-correction performance of the proposed decoder is more than 0.25
    dB better than that of the BP decoder with the same number of random permutations
    at the frame error rate of 10 -4 .

  text: We consider spectral properties and the edge universality of sparse random
    matrices, the class of random matrices that includes the adjacency matrices of
    the Erdős–Rényi graph model G(N, p). We prove a local law for the eigenvalue density
    up to the spectral edges. Under a suitable condition on the sparsity, we also
    prove that the rescaled extremal eigenvalues exhibit GOE Tracy–Widom fluctuations
    if a deterministic shift of the spectral edge due to the sparsity is included.
    For the adjacency matrix of the Erdős–Rényi graph this establishes the Tracy–Widom
    fluctuations of the second largest eigenvalue when p is much larger than N−2/3
    with a deterministic shift of order (Np)−1.

  text: "Background: Transport protein particle (TRAPP) is a multisubunit complex
    that regulates membrane trafficking through the Golgi apparatus. The clinical
    phenotype associated with mutations in various TRAPP subunits has allowed elucidation
    of their functions in specific tissues. The role of some subunits in human disease,
    however, has not been fully established, and their functions remain uncertain.\r\n\r\nObjective:
    We aimed to expand the range of neurodevelopmental disorders associated with mutations
    in TRAPP subunits by exome sequencing of consanguineous families.\r\n\r\nMethods:
    Linkage and homozygosity mapping and candidate gene analysis were used to identify
    homozygous mutations in families. Patient fibroblasts were used to study splicing
    defect and zebrafish to model the disease.\r\n\r\nResults: We identified six individuals
    from three unrelated families with a founder homozygous splice mutation in TRAPPC6B,
    encoding a core subunit of the complex TRAPP I. Patients manifested a neurodevelopmental
    disorder characterised by microcephaly, epilepsy and autistic features, and showed
    splicing defect. Zebrafish trappc6b morphants replicated the human phenotype,
    displaying decreased head size and neuronal hyperexcitability, leading to a lower
    seizure threshold.\r\n\r\nConclusion: This study provides clinical and functional
    evidence of the role of TRAPPC6B in brain development and function."

  text: Animal social networks are shaped by multiple selection pressures, including
    the need to ensure efficient communication and functioning while simultaneously
    limiting disease transmission. Social animals could potentially further reduce
    epidemic risk by altering their social networks in the presence of pathogens,
    yet there is currently no evidence for such pathogen-triggered responses. We tested
    this hypothesis experimentally in the ant Lasius niger using a combination of
    automated tracking, controlled pathogen exposure, transmission quantification,
    and temporally explicit simulations. Pathogen exposure induced behavioral changes
    in both exposed ants and their nestmates, which helped contain the disease by
    reinforcing key transmission-inhibitory properties of the colony's contact network.
    This suggests that social network plasticity in response to pathogens is an effective
    strategy for mitigating the effects of disease in social groups.

  text: We consider the totally asymmetric simple exclusion process in a critical
    scaling parametrized by a≥0, which creates a shock in the particle density of
    order aT−1/3, T the observation time. When starting from step initial data, we
    provide bounds on the limiting law which in particular imply that in the double
    limit lima→∞limT→∞ one recovers the product limit law and the degeneration of
    the correlation length observed at shocks of order 1. This result is shown to
    apply to a general last-passage percolation model. We also obtain bounds on the
    two-point functions of several airy processes.

  text: Although dopamine receptors D1 and D2 play key roles in hippocampal function,
    their synaptic localization within the hippocampus has not been fully elucidated.
    In order to understand precise functions of pre- or postsynaptic dopamine receptors
    (DRs), the development of protocols to differentiate pre- and postsynaptic DRs
    is essential. So far, most studies on determination and quantification of DRs
    did not discriminate between subsynaptic localization. Therefore, the aim of the
    study was to generate a robust workflow for the localization of DRs. This work
    provides the basis for future work on hippocampal DRs, in light that DRs may have
    different functions at pre- or postsynaptic sites. Synaptosomes from rat hippocampi
    isolated by a sucrose gradient protocol were prepared for super-resolution direct
    stochastic optical reconstruction microscopy (dSTORM) using Bassoon as a presynaptic
    zone and Homer1 as postsynaptic density marker. Direct labeling of primary validated
    antibodies against dopamine receptors D1 (D1R) and D2 (D2R) with Alexa Fluor 594
    enabled unequivocal assignment of D1R and D2R to both, pre- and postsynaptic sites.
    D1R immunoreactivity clusters were observed within the presynaptic active zone
    as well as at perisynaptic sites at the edge of the presynaptic active zone. The
    results may be useful for the interpretation of previous studies and the design
    of future work on DRs in the hippocampus. Moreover, the reduction of the complexity
    of brain tissue by the use of synaptosomal preparations and dSTORM technology
    may represent a useful tool for synaptic localization of brain proteins.

  text: We examine recent magnetic torque measurements in two compounds, γ−Li2IrO3
    and RuCl3, which have been discussed as possible realizations of the Kitaev model.
    The analysis of the reported discontinuity in torque, as an external magnetic
    field is rotated across the c axis in both crystals, suggests that they have a
    translationally invariant chiral spin order of the form ⟨Si⋅(Sj×Sk)⟩≠0 in the
    ground state and persisting over a very wide range of magnetic field and temperature.
    An extraordinary |B|B2 dependence of the torque for small fields, beside the usual
    B2 part, is predicted by the chiral spin order. Data for small fields are available
    for γ−Li2IrO3 and are found to be consistent with the prediction upon further
    analysis. Other experiments such as inelastic scattering and thermal Hall effect
    and several questions raised by the discovery of chiral spin order, including
    its topological consequences, are discussed.

  text: Unusual behavior in quantum materials commonly arises from their effective
    low-dimensional physics, reflecting the underlying anisotropy in the spin and
    charge degrees of freedom. Here we introduce the magnetotropic coefficient k = ∂2F/∂θ2,
    the second derivative of the free energy F with respect to the magnetic field
    orientation θ in the crystal. We show that the magnetotropic coefficient can be
    quantitatively determined from a shift in the resonant frequency of a commercially
    available atomic force microscopy cantilever under magnetic field. This detection
    method enables part per 100 million sensitivity and the ability to measure magnetic
    anisotropy in nanogram-scale samples, as demonstrated on the Weyl semimetal NbP.
    Measurement of the magnetotropic coefficient in the spin-liquid candidate RuCl3
    highlights its sensitivity to anisotropic phase transitions and allows a quantitative
    comparison to other thermodynamic coefficients via the Ehrenfest relations.

  text: The anomalous metallic state in the high-temperature superconducting cuprates
    is masked by superconductivity near a quantum critical point. Applying high magnetic
    fields to suppress superconductivity has enabled detailed studies of the normal
    state, yet the direct effect of strong magnetic fields on the metallic state is
    poorly understood. We report the high-field magnetoresistance of thin-film La2–xSrxCuO4
    cuprate in the vicinity of the critical doping, 0.161 ≤ p ≤ 0.190. We find that
    the metallic state exposed by suppressing superconductivity is characterized by
    magnetoresistance that is linear in magnetic fields up to 80 tesla. The magnitude
    of the linear-in-field resistivity mirrors the magnitude and doping evolution
    of the well-known linear-in-temperature resistivity that has been associated with
    quantum criticality in high-temperature superconductors.

  text: 'Weyl fermions are a recently discovered ingredient for correlated states
    of electronic matter. A key difficulty has been that real materials also contain
    non-Weyl quasiparticles, and disentangling the experimental signatures has proven
    challenging. Here we use magnetic fields up to 95 T to drive the Weyl semimetal
    TaAs far into its quantum limit, where only the purely chiral 0th Landau levels
    of the Weyl fermions are occupied. We find the electrical resistivity to be nearly
    independent of magnetic field up to 50 T: unusual for conventional metals but
    consistent with the chiral anomaly for Weyl fermions. Above 50 T we observe a
    two-order-of-magnitude increase in resistivity, indicating that a gap opens in
    the chiral Landau levels. Above 80 T we observe strong ultrasonic attenuation
    below 2 K, suggesting a mesoscopically textured state of matter. These results
    point the way to inducing new correlated states of matter in the quantum limit
    of Weyl semimetals.'

  text: The high-pressure synthesis and incommensurately modulated structure are reported
    for the new compound Sr2Pt8−xAs, with x = 0.715 (5). The structure consists of
    Sr2Pt3As layers alternating with Pt-only corrugated grids. Ab initio calculations
    predict a metallic character with a dominant role of the Pt d electrons. The electrical
    resistivity (ρ) and Seebeck coefficient confirm the metallic character, but surprisingly,
    ρ showed a near-flat temperature dependence. This observation fits the description
    of the Mooij correlation for electrical resistivity in disordered metals, originally
    developed for statistically distributed point defects. The discussed material
    has a long-range crystallographic order, but the high concentration of Pt vacancies,
    incommensurately ordered, strongly influences the electronic conduction properties.
    This result extends the range of validity of the Mooij correlation to long-range
    ordered incommensurately modulated vacancies. Motivated by the layered structure,
    the resistivity anisotropy was measured in a focused-ion-beam micro-fabricated
    well oriented single crystal. A low resistivity anisotropy indicates that the
    layers are electrically coupled and conduction channels along different directions
    are intermixed.

  text: 'Training deep learning models has received tremendous research interest recently.
    In particular, there has been intensive research on reducing the communication
    cost of training when using multiple computational devices, through reducing the
    precision of the underlying data representation. Naturally, such methods induce
    system trade-offs—lowering communication precision could de-crease communication
    overheads and improve scalability; but, on the other hand, it can also reduce
    the accuracy of training. In this paper, we study this trade-off space, and ask:Can
    low-precision communication consistently improve the end-to-end performance of
    training modern neural networks, with no accuracy loss?From the performance point
    of view, the answer to this question may appear deceptively easy: compressing
    communication through low precision should help when the ratio between communication
    and computation is high. However, this answer is less straightforward when we
    try to generalize this principle across various neural network architectures (e.g.,
    AlexNet vs. ResNet),number of GPUs (e.g., 2 vs. 8 GPUs), machine configurations(e.g.,
    EC2 instances vs. NVIDIA DGX-1), communication primitives (e.g., MPI vs. NCCL),
    and even different GPU architectures(e.g., Kepler vs. Pascal). Currently, it is
    not clear how a realistic realization of all these factors maps to the speed up
    provided by low-precision communication. In this paper, we conduct an empirical
    study to answer this question and report the insights.'

  text: "Population protocols are a popular model of distributed computing, in which
    n agents with limited local state interact randomly, and cooperate to collectively
    compute global predicates. Inspired by recent developments in DNA programming,
    an extensive series of papers, across different communities, has examined the
    computability and complexity characteristics of this model. Majority, or consensus,
    is a central task in this model, in which agents need to collectively reach a
    decision as to which one of two states A or B had a higher initial count. Two
    metrics are important: the time that a protocol requires to stabilize to an output
    decision, and the state space size that each agent requires to do so. It is known
    that majority requires Ω(log log n) states per agent to allow for fast (poly-logarithmic
    time) stabilization, and that O(log2 n) states are sufficient. Thus, there is
    an exponential gap between the space upper and lower bounds for this problem.
    This paper addresses this question.\r\n\r\nOn the negative side, we provide a
    new lower bound of Ω(log n) states for any protocol which stabilizes in O(n1–c)
    expected time, for any constant c > 0. This result is conditional on monotonicity
    and output assumptions, satisfied by all known protocols. Technically, it represents
    a departure from previous lower bounds, in that it does not rely on the existence
    of dense configurations. Instead, we introduce a new generalized surgery technique
    to prove the existence of incorrect executions for any algorithm which would contradict
    the lower bound. Subsequently, our lower bound also applies to general initial
    configurations, including ones with a leader. On the positive side, we give a
    new algorithm for majority which uses O(log n) states, and stabilizes in O(log2
    n) expected time. Central to the algorithm is a new leaderless phase clock technique,
    which allows agents to synchronize in phases of Θ(n log n) consecutive interactions
    using O(log n) states per agent, exploiting a new connection between population
    protocols and power-of-two-choices load balancing mechanisms. We also employ our
    phase clock to build a leader election algorithm with a state space of size O(log
    n), which stabilizes in O(log2 n) expected time."

  text: In the Minimum Description Length (MDL) principle, learning from the data
    is equivalent to an optimal coding problem. We show that the codes that achieve
    optimal compression in MDL are critical in a very precise sense. First, when they
    are taken as generative models of samples, they generate samples with broad empirical
    distributions and with a high value of the relevance, defined as the entropy of
    the empirical frequencies. These results are derived for different statistical
    models (Dirichlet model, independent and pairwise dependent spin models, and restricted
    Boltzmann machines). Second, MDL codes sit precisely at a second order phase transition
    point where the symmetry between the sampled outcomes is spontaneously broken.
    The order parameter controlling the phase transition is the coding cost of the
    samples. The phase transition is a manifestation of the optimality of MDL codes,
    and it arises because codes that achieve a higher compression do not exist. These
    results suggest a clear interpretation of the widespread occurrence of statistical
    criticality as a characterization of samples which are maximally informative on
    the underlying generative process.

  text: Escaping local optima is one of the major obstacles to function optimisation.
    Using the metaphor of a fitness landscape, local optima correspond to hills separated
    by fitness valleys that have to be overcome. We define a class of fitness valleys
    of tunable difficulty by considering their length, representing the Hamming path
    between the two optima and their depth, the drop in fitness. For this function
    class we present a runtime comparison between stochastic search algorithms using
    different search strategies. The (1+1) EA is a simple and well-studied evolutionary
    algorithm that has to jump across the valley to a point of higher fitness because
    it does not accept worsening moves (elitism). In contrast, the Metropolis algorithm
    and the Strong Selection Weak Mutation (SSWM) algorithm, a famous process in population
    genetics, are both able to cross the fitness valley by accepting worsening moves.
    We show that the runtime of the (1+1) EA depends critically on the length of the
    valley while the runtimes of the non-elitist algorithms depend crucially on the
    depth of the valley. Moreover, we show that both SSWM and Metropolis can also
    efficiently optimise a rugged function consisting of consecutive valleys.

  text: The recent demand of multifunctional materials and devices for advanced applications
    in energy conversion and data storage resulted into a revival of multiferroics,
    that is, materials characterized by the coexistence of ferromagnetism and ferroelectricity.
    Despite intense efforts made in the past decade, single-phase room temperature
    multiferroics are yet to be discovered/fabricated. Nanostructured ferroic materials
    could potentially exhibit multiferroism since a high fraction of their atoms/ions
    are superficial, thereby altering significantly the properties of the bulk phase.
    Alternately, a magnetic order can be induced into ferroelectric materials upon
    aliovalent doping with magnetic ions. Here, we report on the synthesis of aggregate-free
    single-phase transition-metal-doped BaTiO3 quasi-monodisperse cuboidal nanocrystals
    (NC) which exhibit multiferroic properties at room temperature and can be suitable
    for applications in data storage. The proposed synthetic route allows the inclusion
    of a high concentration of magnetic ions such as Mn+ (M = Cr, Mn, Fe, Co) up to
    a nominal concentration of 4% without the formation of any secondary phase. The
    size of the nanocrystals was controlled in a wide range from ∼15 up to ∼70 nm
    by varying the reaction time from 48 to 144 h. The presence of unpaired electrons
    and their magnetic ordering have been probed by electron paramagnetic resonance
    spectroscopy (EPR), and a vibrating sample magnetometer (VSM). Likewise, an acentric
    structure, associated with the existence of a dielectric polarization, was observed
    by lattice dynamics analysis and piezoresponse force microscopy (PFM). These results
    show that high-quality titanium-containing perovskite nanocrystals which display
    multiferroic properties at room temperature can be fabricated via soft solution-based
    synthetic routes, and the properties of these materials can be modulated by changing
    the size of the nanocrystals and the concentration of the dopant thereby opening
    the door to the design and study of single-phase multiferroic materials.

  text: 'Solid alkali metal carbonates are universal passivation layer components
    of intercalation battery materials and common side products in metal‐O2 batteries,
    and are believed to form and decompose reversibly in metal‐O2/CO2 cells. In these
    cathodes, Li2CO3 decomposes to CO2 when exposed to potentials above 3.8 V vs.
    Li/Li+. However, O2 evolution, as would be expected according to the decomposition
    reaction 2 Li2CO3→4 Li++4 e−+2 CO2+O2, is not detected. O atoms are thus unaccounted
    for, which was previously ascribed to unidentified parasitic reactions. Here,
    we show that highly reactive singlet oxygen (1O2) forms upon oxidizing Li2CO3
    in an aprotic electrolyte and therefore does not evolve as O2. These results have
    substantial implications for the long‐term cyclability of batteries: they underpin
    the importance of avoiding 1O2 in metal‐O2 batteries, question the possibility
    of a reversible metal‐O2/CO2 battery based on a carbonate discharge product, and
    help explain the interfacial reactivity of transition‐metal cathodes with residual
    Li2CO3.'

  text: Hydrogelation, the self-assembly of molecules into soft, water-loaded networks,
    is one way to bridge the structural gap between single molecules and functional
    materials. The potential of hydrogels, such as those based on perylene bisimides,
    lies in their chemical, physical, optical, and electronic properties, which are
    governed by the supramolecular structure of the gel. However, the structural motifs
    and their precise role for long-range conductivity are yet to be explored. Here,
    we present a comprehensive structural picture of a perylene bisimide hydrogel,
    suggesting that its long-range conductivity is limited by charge transfer between
    electronic backbones. We reveal nanocrystalline ribbon-like structures as the
    electronic and structural backbone units between which charge transfer is mediated
    by polar solvent bridges. We exemplify this effect with sensing, where exposure
    to polar vapor enhances conductivity by 5 orders of magnitude, emphasizing the
    crucial role of the interplay between structural motif and surrounding medium
    for the rational design of devices based on nanocrystalline hydrogels.

  text: The solid electrolyte interphase (SEI) in Li and Na ion batteries forms when
    highly reducing or oxidizing electrode materials come into contact with a liquid
    organic electrolyte. Its ability to form a mechanically robust, ion-conducting,
    and electron-insulating layer critically determines performance, cycle life, and
    safety. Li or Na alkyl carbonates (LiAC and NaAC, respectively) are lead SEI components
    in state-of-the-art carbonate based electrolytes, and our fundamental understanding
    of their charge transport and mechanical properties may hold the key to designing
    electrolytes forming an improved SEI. We synthesized a homologous series of LiACs
    and NaACs from methyl to octyl analogues and characterized them with respect to
    structure, ionic conductivity, and stiffness. The compounds assume layered structures
    except for the lithium methyl carbonate. Room-temperature conductivities were
    found to be ∼10–9 S cm–1 for lithium methyl carbonate, <10–12 S cm–1 for the other
    LiACs, and <10–12 S cm–1 for the NaACs with ion transport mostly attributed to
    grain boundaries. While LiACs show stiffnesses of ∼1 GPa, NaACs become significantly
    softer with increasing chain lengths. These findings will help to more precisely
    interpret the complex results from charge transport and mechanical characterization
    of real SEIs and can give a rationale for influencing the SEI’s mechanical properties
    via the electrolyte.
