  text: Transcription factors (TFs) regulate gene expression through chromatin where
    nucleosomes restrict DNA access. To study how TFs bind nucleosome-occupied motifs,
    we focused on the reprogramming factors OCT4 and SOX2 in mouse embryonic stem
    cells. We determined TF engagement throughout a nucleosome at base-pair resolution
    in vitro, enabling structure determination by cryo–electron microscopy at two
    preferred positions. Depending on motif location, OCT4 and SOX2 differentially
    distort nucleosomal DNA. At one position, OCT4-SOX2 removes DNA from histone H2A
    and histone H3; however, at an inverted motif, the TFs only induce local DNA distortions.
    OCT4 uses one of its two DNA-binding domains to engage DNA in both structures,
    reading out a partial motif. These findings explain site-specific nucleosome engagement
    by the pluripotency factors OCT4 and SOX2, and they reveal how TFs distort nucleosomes
    to access chromatinized motifs.

  text: Mammalian circadian rhythms are generated by a transcription-based feedback
    loop in which CLOCK:BMAL1 drives transcription of its repressors (PER1/2, CRY1/2),
    which ultimately interact with CLOCK:BMAL1 to close the feedback loop with ~24
    hr periodicity. Here we pinpoint a key difference between CRY1 and CRY2 that underlies
    their differential strengths as transcriptional repressors. Both cryptochromes
    bind the BMAL1 transactivation domain similarly to sequester it from coactivators
    and repress CLOCK:BMAL1 activity. However, we find that CRY1 is recruited with
    much higher affinity to the PAS domain core of CLOCK:BMAL1, allowing it to serve
    as a stronger repressor that lengthens circadian period. We discovered a dynamic
    serine-rich loop adjacent to the secondary pocket in the photolyase homology region
    (PHR) domain that regulates differential binding of cryptochromes to the PAS domain
    core of CLOCK:BMAL1. Notably, binding of the co-repressor PER2 remodels the serine
    loop of CRY2, making it more CRY1-like and enhancing its affinity for CLOCK:BMAL1.

  text: 'A new window is opening in high-energy astronomy: X-ray polarimetry. With
    many missions currently under development and scheduled to launch as early as
    2021, observations of the X-ray polarization of accreting X-ray pulsars will soon
    be available. As polarization is particularly sensitive to the geometry of the
    emission region, the upcoming polarimeters will shed new light on the emission
    mechanism of these objects, provided that we have sound theoretical models that
    agree with current spectroscopic and timing observation and that can make predictions
    of the polarization parameters of the emission. We here present a new model for
    the polarized emission of accreting X-ray pulsars in the accretion column scenario
    that for the first time takes into account the macroscopic structure and dynamics
    of the accretion region and the propagation of the radiation towards the observer,
    including relativistic beaming, gravitational lensing, and quantum electrodynamics.
    In this paper, we present all the details of the model, while in a companion paper,
    we apply our model to predict the polarization parameters of the bright X-ray
    pulsar Hercules X-1.'

  text: We employ our new model for the polarized emission of accreting X-ray pulsars
    to describe the emission from the luminous X-ray pulsar Hercules X-1. In contrast
    with previous works, our model predicts the polarization parameters independently
    of spectral formation, and considers the structure and dynamics of the accretion
    column, as well as the additional effects on propagation due to general relativity
    and quantum electrodynamics. We find that our model can describe the observed
    pulse fraction and the pulse shape of the main peak, as well as the modulation
    of the cyclotron line with phase. We pick two geometries, assuming a single accretion
    column or two columns at the magnetic poles, that can describe current observations
    of pulse shape and cyclotron modulation with phase. Both models predict a high
    polarization fraction, between 60 and 80 per cent in the 1–10 keV range, that
    is phase and energy dependent, and that peaks at the same phase as the intensity.
    The phase and energy dependence of the polarization fraction and of the polarization
    angle can help discern between the different geometries.

  text: "Using photometry collected with the Zwicky Transient Facility, we are conducting
    an ongoing survey for binary systems with short orbital periods (\r\n with the
    goal of identifying new gravitational-wave sources detectable by the upcoming
    Laser Interferometer Space Antenna (LISA). We present a sample of 15 binary systems
    discovered thus far, with orbital periods ranging from 6.91 to 56.35 minutes.
    Of the 15 systems, seven are eclipsing systems that do not show signs of significant
    mass transfer. Additionally, we have discovered two AM Canum Venaticorum systems
    and six systems exhibiting primarily ellipsoidal variations in their lightcurves.
    We present follow-up spectroscopy and high-speed photometry confirming the nature
    of these systems, estimates of their LISA signal-to-noise ratios, and a discussion
    of their physical characteristics."

  text: When a star exhausts its nuclear fuel, it either explodes as a supernova or
    more quiescently becomes a white dwarf, an object about half the mass of our Sun
    with a radius of about that of the Earth. About one-fifth of white dwarfs exhibit
    the presence of magnetic fields, whose origin has long been debated as either
    the product of previous stages of evolution or of binary interactions. We here
    report the discovery of two massive and magnetic white-dwarf members of young
    star clusters in the Gaia second data release (DR2) database, while a third massive
    and magnetic cluster white dwarf was already reported in a previous paper. These
    stars are most likely the product of single-star evolution and therefore challenge
    the merger scenario as the only way to produce magnetic white dwarfs. The progenitor
    masses of these stars are all above 5 solar masses, and there are only two other
    cluster white dwarfs whose distances have been unambiguously measured with Gaia
    and whose progenitors' masses fall in this range. This high incidence of magnetic
    white dwarfs indicates that intermediate-mass progenitors are more likely to produce
    magnetic remnants and that a fraction of magnetic white dwarfs forms from intermediate-mass
    stars.

  text: We describe a new implementation of a broad-band soft X-ray polarimeter, substantially
    based on a previous design. This implementation, the Pioneer Soft X-ray Polarimeter
    (PiSoX) is a SmallSat, designed for NASA’s call for Astrophysics Pioneers, small
    missions that could be CubeSats, balloon experiments, or SmallSats. As in REDSoX,
    the grating arrangement is designed optimally for the purpose of polarimetry with
    broad-band focussing optics by matching the dispersion of the spectrometer channels
    to laterally graded multilayers (LGMLs). The system can achieve polarization modulation
    factors over 90%. For PiSoX, the optics are lightweight Si mirrors in a one-bounce
    parabolic configuration. High efficiency, blazed gratings from opposite sectors
    are oriented to disperse to a LGML forming a channel covering the wavelength range
    from 35 Å to 75 Å (165 - 350 eV). Upon satellite rotation, the intensities of
    the dispersed spectra, after reflection and polarizing by the LGMLs, give the
    three Stokes parameters needed to determine a source’s linear polarization fraction
    and orientation. The design can be extended to higher energies as LGMLs are developed
    further. We describe examples of the potential scientific return from instruments
    based on this design.

  text: 'We propose a high-time-resolution, high-spectral-resolution X-ray telescope
    that uses transition-edge sensors (TES) as detectors and collector optics to direct
    the X-rays onto the focal plane, providing a large effective area in a small satellite.
    The key science driver of the instrument is to study neutron stars and accreting
    black holes. The proposed instrument is built upon two technologies that are already
    at high TRL: TES X-ray detectors and collector optics.'

abstract:
- lang: eng
  text: In this paper, we present the first Asynchronous Distributed Key Generation
    (ADKG) algorithm which is also the first distributed key generation algorithm
    that can generate cryptographic keys with a dual (f,2f+1)-threshold (where f is
    the number of faulty parties). As a result, using our ADKG we remove the trusted
    setup assumption that the most scalable consensus algorithms make. In order to
    create a DKG with a dual (f,2f+1)- threshold we first answer in the affirmative
    the open question posed by Cachin et al. [7] on how to create an Asynchronous
    Verifiable Secret Sharing (AVSS) protocol with a reconstruction threshold of f+1<k
    łe 2f+1, which is of independent interest. Our High-threshold-AVSS (HAVSS) uses
    an asymmetric bivariate polynomial to encode the secret. This enables the reconstruction
    of the secret only if a set of k nodes contribute while allowing an honest node
    that did not participate in the sharing phase to recover his share with the help
    of f+1 honest parties. Once we have HAVSS we can use it to bootstrap scalable
    partially synchronous consensus protocols, but the question on how to get a DKG
    in asynchrony remains as we need a way to produce common randomness. The solution
    comes from a novel Eventually Perfect Common Coin (EPCC) abstraction that enables
    the generation of a common coin from n concurrent HAVSS invocations. EPCC's key
    property is that it is eventually reliable, as it might fail to agree at most
    f times (even if invoked a polynomial number of times). Using EPCC we implement
    an Eventually Efficient Asynchronous Binary Agreement (EEABA) which is optimal
    when the EPCC agrees and protects safety when EPCC fails. Finally, using EEABA
    we construct the first ADKG which has the same overhead and expected runtime as
    the best partially-synchronous DKG (O(n4) words, O(f) rounds). As a corollary
    of our ADKG, we can also create the first Validated Asynchronous Byzantine Agreement
    (VABA) that does not need a trusted dealer to setup threshold signatures of degree
    n-f. Our VABA has an overhead of expected O(n2) words and O(1) time per instance,
    after an initial O(n4) words and O(f) time bootstrap via ADKG.
acknowledgement: We would like to thank Ittai Abraham for the discussions and guidance
  during the initial conception of the project, especially for HAVSS. Furthermore,
  we would like to thank the anonymous reviewers for pointing out the relevance of
  this work to MPC protocols.

  text: Magnetism typically arises from the joint effect of Fermi statistics and repulsive
    Coulomb interactions, which favours ground states with non-zero electron spin.
    As a result, controlling spin magnetism with electric fields—a longstanding technological
    goal in spintronics and multiferroics1,2—can be achieved only indirectly. Here
    we experimentally demonstrate direct electric-field control of magnetic states
    in an orbital Chern insulator3,4,5,6, a magnetic system in which non-trivial band
    topology favours long-range order of orbital angular momentum but the spins are
    thought to remain disordered7,8,9,10,11,12,13,14. We use van der Waals heterostructures
    consisting of a graphene monolayer rotationally faulted with respect to a Bernal-stacked
    bilayer to realize narrow and topologically non-trivial valley-projected moiré
    minibands15,16,17. At fillings of one and three electrons per moiré unit cell
    within these bands, we observe quantized anomalous Hall effects18 with transverse
    resistance approximately equal to h/2e2 (where h is Planck’s constant and e is
    the charge on the electron), which is indicative of spontaneous polarization of
    the system into a single-valley-projected band with a Chern number equal to two.
    At a filling of three electrons per moiré unit cell, we find that the sign of
    the quantum anomalous Hall effect can be reversed via field-effect control of
    the chemical potential; moreover, this transition is hysteretic, which we use
    to demonstrate non-volatile electric-field-induced reversal of the magnetic state.
    A theoretical analysis19 indicates that the effect arises from the topological
    edge states, which drive a change in sign of the magnetization and thus a reversal
    in the favoured magnetic state. Voltage control of magnetic states can be used
    to electrically pattern non-volatile magnetic-domain structures hosting chiral
    edge states, with applications ranging from reconfigurable microwave circuit elements
    to ultralow-power magnetic memories.

  text: The understanding of material systems with strong electron-electron interactions
    is the central problem in modern condensed matter physics. Despite this, the essential
    physics of many of these materials is still not understood and we have no overall
    perspective on their properties. Moreover, we have very little ability to make
    predictions in this class of systems. In this manuscript we share our personal
    views of what the major open problems are in correlated electron systems and we
    discuss some possible routes to make progress in this rich and fascinating field.
    This manuscript is the result of the vigorous discussions and deliberations that
    took place at Johns Hopkins University during a three-day workshop January 27,
    28, and 29, 2020 that brought together six senior scientists and 46 more junior
    scientists. Our hope, is that the topics we have presented will provide inspiration
    for others working in this field and motivation for the idea that significant
    progress can be made on very hard problems if we focus our collective energies.

  text: The family of feedback alignment (FA) algorithms aims to provide a more biologically
    motivated alternative to backpropagation (BP), by substituting the computations
    that are unrealistic to be implemented in physical brains. While FA algorithms
    have been shown to work well in practice, there is a lack of rigorous theory proofing
    their learning capabilities. Here we introduce the first feedback alignment algorithm
    with provable learning guarantees. In contrast to existing work, we do not require
    any assumption about the size or depth of the network except that it has a single
    output neuron, i.e., such as for binary classification tasks. We show that our
    FA algorithm can deliver its theoretical promises in practice, surpassing the
    learning performance of existing FA methods and matching backpropagation in binary
    classification tasks. Finally, we demonstrate the limits of our FA variant when
    the number of output neurons grows beyond a certain quantity.

  text: We propose a neural information processing system obtained by re-purposing
    the function of a biological neural circuit model to govern simulated and real-world
    control tasks. Inspired by the structure of the nervous system of the soil-worm,
    C. elegans, we introduce ordinary neural circuits (ONCs), defined as the model
    of biological neural circuits reparameterized for the control of alternative tasks.
    We first demonstrate that ONCs realize networks with higher maximum flow compared
    to arbitrary wired networks. We then learn instances of ONCs to control a series
    of robotic tasks, including the autonomous parking of a real-world rover robot.
    For reconfiguration of the purpose of the neural circuit, we adopt a search-based
    optimization algorithm. Ordinary neural circuits perform on par and, in some cases,
    significantly surpass the performance of contemporary deep learning models. ONC
    networks are compact, 77% sparser than their counterpart neural controllers, and
    their neural dynamics are fully interpretable at the cell-level.

  text: High quality graphene heterostructures host an array of fractional quantum
    Hall isospin ferromagnets with diverse spin and valley orders. While a variety
    of phase transitions have been observed, disentangling the isospin phase diagram
    of these states is hampered by the absence of direct probes of spin and valley
    order. I will describe nonlocal transport measurements based on launching spin
    waves from a gate defined lateral heterojunction, performed in ultra-clean Corbino
    geometry graphene devices. At high magnetic fields, we find that the spin-wave
    transport signal is detected in all FQH states between ν = 0 and 1; however, between
    ν = 1 and 2 only odd numerator FQH states show finite nonlocal transport, despite
    the identical ground state spin polarizations in odd- and even numerator states.
    The results reveal that the neutral spin-waves are both spin and sublattice polarized
    making them a sensitive probe of ground state sublattice structure. Armed with
    this understanding, we use nonlocal transport signal to a magnetic field tuned
    isospin phase transition, showing that the emergent even denominator state at
    ν = 1/2 in monolayer graphene is indeed a multicomponent state featuring equal
    populations on each sublattice.

  text: We experimentally investigate twisted van der Waals heterostructures of monolayer
    graphene rotated with respect to a bernal stacked graphene bilayer. We report
    transport measurements for devices with twist angles between 0.9 and 1.4°. The
    electric field allows efficient tuning of the width, isolation and the topology
    of the moiré bands in this system. By comparing magnetoresistance measurements
    to numerical simulations, we develop an understanding of the band structure. Finally,
    we observe correlated states at half- and quarter-fillings, which arise when narrow
    moire sublattice band is isolated by energy gaps from dispersive bands. We investigate
    the effects of in-plane and out-of-plane magnetic field on these states and discuss
    the implication for their spin- and valley- polarization.

  text: We report the observation of a quantized anomalous Hall effect in a moiré
    heterostructure consisting of twisted bilayer graphene aligned to an encapsulating
    hBN substrate. The effect occurs at a density of 3 electrons per superlattice
    unit cell, where we observe magnetic hysteresis and a Hall resistance quantized
    to within 0.1% of the resistance quantum at temperatures as high as 3K. In this
    first of 3 talks, I will describe the fabrication procedure for our device as
    well as basic transport characterization measurements. I will introduce the phenomenology
    of twisted bilayer graphene and present evidence for hBN alignment as manifested
    in the hierarchy of symmetry-breaking gaps and anomalous magnetoresistance.

  text: This is the second of three talks describing the observation and characterization
    of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
    to hexagonal boron nitride. I will compare the qualitative and quantitative features
    of this observed quantum anomalous Hall state to traditional systems engineered
    from thin film (Bi,Sb)2Te3 topological insulators. In particular, we find that
    the measured electronic energy gap of ~30K is several times higher than the Curie
    temperature, consistent with a lack of disorder associated with magnetic dopants.
    In this system, the quantization arises from spontaneous ferromagnetic polarization
    into a single spin and valley moiré subband, which is topological despite the
    lack of spin orbit coupling. I will also discuss the observation of current induced
    switching, which allows the magnetic state of the heterostructure to be controllably
    reversed with currents as small as a few nanoamperes.

  text: This is the third of three talks describing the observation and characterization
    of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
    to hexagonal boron nitride. In this segment I will present scanning probe magnetometry
    data acquired using a nanoSQUID-on-tip microscope, which provides ~150 nm spatial
    resolution and a field sensitivity of ~10 nT/rtHz. We study the distribution of
    magnetic domains within the device as a function of density, magnetic field training,
    and DC current. Our data allow us to constrain the magnitude of the orbital magnetic
    moment of the electrons in the QAH state. Comparison with simultaneously acquired
    transport data allows us to precisely correlate single domain dynamics with discrete
    jumps in the observed anomalous Hall signal.
