  text: RNA polymerase (Pol) II produces messenger RNA during transcription of protein-coding
    genes in all eukaryotic cells. The Pol II structure is known at high resolution
    from X-ray crystallography for two yeast species1-3. Structural studies of mammalian
    Pol II, however, remain limited to low-resolution electron microscopy analysis
    of human Pol II and its complexes with various proteins4-10. Here we report the
    3.4 Å resolution cryo-electron microscopy structure of mammalian Pol II in the
    form of a transcribing complex comprising DNA template and RNA transcript. We
    use bovine Pol II, which is identical to the human enzyme except for seven amino-acid
    residues. The obtained atomic model closely resembles its yeast counterpart, but
    also reveals unknown features. Binding of nucleic acids to the polymerase involves
    'induced fit' of the mobile Pol II clamp and active centre region. DNA downstream
    of the transcription bubble contacts a conserved 'TPSA motif' in the jaw domain
    of the Pol II subunit RPB5, an interaction that is apparently already established
    during transcription initiation7. Upstream DNA emanates from the active centre
    cleft at an angle of approximately 105° with respect to downstream DNA. This position
    of upstream DNA allows for binding of the general transcription elongation factor
    DSIF (SPT4-SPT5) that we localize over the active centre cleft in a conserved
    position on the clamp domain of Pol II. Our results define the structure of mammalian
    Pol II in its functional state, indicate that previous crystallographic analysis
    of yeast Pol II is relevant for understanding gene transcription in all eukaryotes,
    and provide a starting point for a mechanistic analysis of human transcription.

  text: Metallic transition-metal dichalcogenides (TMDCs) are benchmark systems for
    studying and controlling intertwined electronic orders in solids, with superconductivity
    developing from a charge-density wave state. The interplay between such phases
    is thought to play a critical role in the unconventional superconductivity of
    cuprates, Fe-based and heavy-fermion systems, yet even for the more moderately-correlated
    TMDCs, their nature and origins have proved controversial. Here, we study a prototypical
    example, 2H-NbSe2, by spin- and angle-resolved photoemission and first-principles
    theory. We find that the normal state, from which its hallmark collective phases
    emerge, is characterized by quasiparticles whose spin is locked to their valley
    pseudospin. This results from a combination of strong spin–orbit interactions
    and local inversion symmetry breaking, while interlayer coupling further drives
    a rich three-dimensional momentum dependence of the underlying Fermi-surface spin
    texture. These findings necessitate a re-investigation of the nature of charge
    order and superconducting pairing in NbSe2 and related TMDCs.

  text: Visualizing molecular localization at high resolution contributes to understanding
    of their functions and roles in physiological and pathological conditions. Sodium
    dodecyl sulfate-digested freeze-fracture replica labeling (SDS-FRL) is a powerful
    electron microscopy method to study high-resolution two-dimensional distribution
    of transmembrane proteins and their tightly associated proteins on platinum-carbon
    replica. During treatment with SDS, unfixed proteins and intracellular organelle
    are dissolved and integral membrane proteins captured and stabilized by carbon
    and platinum deposition are denatured, retaining most of their antigenicity, and
    exposed on exoplasmic and protoplasmic surfaces of lipid monolayers. The exposure
    of these antigens on the surface of replica facilitates the accessibility of antibodies
    and therefore provides higher labeling efficiency than those obtained with other
    immunoelectron microscopy techniques. In this chapter, we describe the protocols
    of SDS-FRL adapted for mammalian brain samples and an additional procedure for
    fluorescence-guided electron microscopy for replica immunolabeling.

  text: 'When applying machine learning techniques to real-world problems, prior knowledge
    plays a crucial role in enriching the learning system. This prior knowledge is
    typically defined by domain experts and can be integrated into machine learning
    algorithms in a variety of ways: as a preference of certain prediction functions
    over others, as a Bayesian prior over parameters, or as additional information
    about the samples in the training set used for learning a prediction function.
    The latter setup is called learning using privileged information (LUPI) and was
    adopted by Vapnik and Vashist in (Neural Netw, 2009). Formally, LUPI refers to
    the setting when, in addition to the main data modality, the learning system has
    access to an extra source of information about the training examples. The additional
    source of information is only available during training and therefore is called
    privileged. The main goal of LUPI is to utilize privileged information and to
    learn a better model in the main data modality than one would learn without the
    privileged source. As an illustration, for protein classification based on amino-acid
    sequences, the protein tertiary structure can be considered additional information.
    Another example is recognizing objects in images; the textual information in the
    form of image tags contains additional object descriptions and can be used as
    privileged.'

  text: We introduce a scheme for preparation, manipulation, and read out of Majorana
    zero modes in semiconducting wires with mesoscopic superconducting islands. Our
    approach synthesizes recent advances in materials growth with tools commonly used
    in quantum-dot experiments, including gate control of tunnel barriers and Coulomb
    effects, charge sensing, and charge pumping. We outline a sequence of milestones
    interpolating between zero-mode detection and quantum computing that includes
    (1) detection of fusion rules for non-Abelian anyons using either proximal charge
    sensors or pumped current, (2) validation of a prototype topological qubit, and
    (3) demonstration of non-Abelian statistics by braiding in a branched geometry.
    The first two milestones require only a single wire with two islands, and additionally
    enable sensitive measurements of the system\'s excitation gap, quasiparticle poisoning
    rates, residual Majorana zero-mode splittings, and topological-qubit coherence
    times. These pre-braiding experiments can be adapted to other manipulation and
    read out schemes as well.

  text: Feedback loops in biological networks, among others, enable differentiation
    and cell cycle progression, and increase robustness in signal transduction. In
    natural networks, feedback loops are often complex and intertwined, making it
    challenging to identify which loops are mainly responsible for an observed behavior.
    However, minimal synthetic replicas could allow for such identification. Here,
    we engineered a synthetic permease-inducer-repressor system in Saccharomyces cerevisiae
    to analyze if a transport-mediated positive feedback loop could be a core mechanism
    for the switch-like behavior in the regulation of metabolic gene networks such
    as the S. cerevisiae GAL system or the Escherichia coli lac operon. We characterized
    the synthetic circuit using deterministic and stochastic mathematical models.
    Similar to its natural counterparts, our synthetic system shows bistable and hysteretic
    behavior, and the inducer concentration range for bistability as well as the switching
    rates between the two stable states depend on the repressor concentration. Our
    results indicate that a generic permease–inducer–repressor circuit with a single
    feedback loop is sufficient to explain the experimentally observed bistable behavior
    of the natural systems. We anticipate that the approach of reimplementing natural
    systems with orthogonal parts to identify crucial network components is applicable
    to other natural systems such as signaling pathways.

  text: Majorana zero modes are quasiparticle excitations in condensed matter systems
    that have been proposed as building blocks of fault-tolerant quantum computers.
    They are expected to exhibit non-Abelian particle statistics, in contrast to the
    usual statistics of fermions and bosons, enabling quantum operations to be performed
    by braiding isolated modes around one another. Quantum braiding operations are
    topologically protected insofar as these modes are pinned near zero energy, with
    the departure from zero expected to be exponentially small as the modes become
    spatially separated. Following theoretical proposals, several experiments have
    identified signatures of Majorana modes in nanowires with proximity-induced superconductivity
    and atomic chains, with small amounts of mode splitting potentially explained
    by hybridization of Majorana modes. Here, we use Coulomb-blockade spectroscopy
    in an InAs nanowire segment with epitaxial aluminium, which forms a proximity-induced
    superconducting Coulomb island (a â ∼ Majorana islandâ (tm)) that is isolated
    from normal-metal leads by tunnel barriers, to measure the splitting of near-zero-energy
    Majorana modes. We observe exponential suppression of energy splitting with increasing
    wire length. For short devices of a few hundred nanometres, sub-gap state energies
    oscillate as the magnetic field is varied, as is expected for hybridized Majorana
    modes. Splitting decreases by a factor of about ten for each half a micrometre
    of increased wire length. For devices longer than about one micrometre, transport
    in strong magnetic fields occurs through a zero-energy state that is energetically
    isolated from a continuum, yielding uniformly spaced Coulomb-blockade conductance
    peaks, consistent with teleportation via Majorana modes. Our results help to explain
    the trivial-to-topological transition in finite systems and to quantify the scaling
    of topological protection with end-mode separation.

  text: 'Recent experiments have produced mounting evidence of Majorana zero modes
    in nanowire-superconductor hybrids. Signatures of an expected topological phase
    transition accompanying the onset of these modes nevertheless remain elusive.
    We investigate a fundamental question concerning this issue: Do well-formed Majorana
    modes necessarily entail a sharp phase transition in these setups? Assuming reasonable
    parameters, we argue that finite-size effects can dramatically smooth this putative
    transition into a crossover, even in systems large enough to support well-localized
    Majorana modes. We propose overcoming such finite-size effects by examining the
    behavior of low-lying excited states through tunneling spectroscopy. In particular,
    the excited-state energies exhibit characteristic field and density dependence,
    and scaling with system size, that expose an approaching topological phase transition.
    We suggest several experiments for extracting the predicted behavior. As a useful
    byproduct, the protocols also allow one to measure the wire''s spin-orbit coupling
    directly in its superconducting environment.'

  text: Nucleation processes are at the heart of a large number of phenomena, from
    cloud formation to protein crystallization. A recently emerging area where nucleation
    is highly relevant is the initiation of filamentous protein self-assembly, a process
    that has broad implications in many research areas ranging from medicine to nanotechnology.
    As such, spontaneous nucleation of protein fibrils has received much attention
    in recent years with many theoretical and experimental studies focusing on the
    underlying physical principles. In this paper we make a step forward in this direction
    and explore the early time behaviour of filamentous protein growth in the context
    of nucleation theory. We first provide an overview of the thermodynamics and kinetics
    of spontaneous nucleation of protein filaments in the presence of one relevant
    degree of freedom, namely the cluster size. In this case, we review how key kinetic
    observables, such as the reaction order of spontaneous nucleation, are directly
    related to the physical size of the critical nucleus. We then focus on the increasingly
    prominent case of filament nucleation that includes a conformational conversion
    of the nucleating building-block as an additional slow step in the nucleation
    process. Using computer simulations, we study the concentration dependence of
    the nucleation rate. We find that, under these circumstances, the reaction order
    of spontaneous nucleation with respect to the free monomer does no longer relate
    to the overall physical size of the nucleating aggregate but rather to the portion
    of the aggregate that actively participates in the conformational conversion.
    Our results thus provide a novel interpretation of the common kinetic descriptors
    of protein filament formation, including the reaction order of the nucleation
    step or the scaling exponent of lag times, and put into perspective current theoretical
    descriptions of protein aggregation.

  text: The interplay of membrane proteins is vital for many biological processes,
    such as cellular transport, cell division, and signal transduction between nerve
    cells. Theoretical considerations have led to the idea that the membrane itself
    mediates protein self-organization in these processes through minimization of
    membrane curvature energy. Here, we present a combined experimental and numerical
    study in which we quantify these interactions directly for the first time. In
    our experimental model system we control the deformation of a lipid membrane by
    adhering colloidal particles. Using confocal microscopy, we establish that these
    membrane deformations cause an attractive interaction force leading to reversible
    binding. The attraction extends over 2.5 times the particle diameter and has a
    strength of three times the thermal energy (−3.3 kBT). Coarse-grained Monte-Carlo
    simulations of the system are in excellent agreement with the experimental results
    and prove that the measured interaction is independent of length scale. Our combined
    experimental and numerical results reveal membrane curvature as a common physical
    origin for interactions between any membrane-deforming objects, from nanometre-sized
    proteins to micrometre-sized particles.

  text: The ability of biological molecules to replicate themselves is the foundation
    of life, requiring a complex cellular machinery. However, a range of aberrant
    processes involve the self-replication of pathological protein structures without
    any additional assistance. One example is the autocatalytic generation of pathological
    protein aggregates, including amyloid fibrils, involved in neurodegenerative disorders.
    Here, we use computer simulations to identify the necessary requirements for the
    self-replication of fibrillar assemblies of proteins. We establish that a key
    physical determinant for this process is the affinity of proteins for the surfaces
    of fibrils. We find that self-replication can take place only in a very narrow
    regime of inter-protein interactions, implying a high level of sensitivity to
    system parameters and experimental conditions. We then compare our theoretical
    predictions with kinetic and biosensor measurements of fibrils formed from the
    Aβ peptide associated with Alzheimer’s disease. Our results show a quantitative
    connection between the kinetics of self-replication and the surface coverage of
    fibrils by monomeric proteins. These findings reveal the fundamental physical
    requirements for the formation of supra-molecular structures able to replicate
    themselves, and shed light on mechanisms in play in the proliferation of protein
    aggregates in nature.

  text: Using non-equilibrium molecular dynamics simulations, it has been recently
    demonstrated that water molecules align in response to an imposed temperature
    gradient, resulting in an effective electric field. Here, we investigate how thermally
    induced fields depend on the underlying treatment of long-ranged interactions.
    For the short-ranged Wolf method and Ewald summation, we find the peak strength
    of the field to range between 2 × 107 and 5 × 107 V/m for a temperature gradient
    of 5.2 K/Å. Our value for the Wolf method is therefore an order of magnitude lower
    than the literature value [J. A. Armstrong and F. Bresme, J. Chem. Phys. 139,
    014504 (2013); J. Armstrong et al., J. Chem. Phys. 143, 036101 (2015)]. We show
    that this discrepancy can be traced back to the use of an incorrect kernel in
    the calculation of the electrostatic field. More seriously, we find that the Wolf
    method fails to predict correct molecular orientations, resulting in dipole densities
    with opposite sign to those computed using Ewald summation. By considering two
    different multipole expansions, we show that, for inhomogeneous polarisations,
    the quadrupole contribution can be significant and even outweigh the dipole contribution
    to the field. Finally, we propose a more accurate way of calculating the electrostatic
    potential and the field. In particular, we show that averaging the microscopic
    field analytically to obtain the macroscopic Maxwell field reduces the error bars
    by up to an order of magnitude. As a consequence, the simulation times required
    to reach a given statistical accuracy decrease by up to two orders of magnitude.

  text: We study phase behaviour of lipid-bilayer vesicles functionalised by ligand–receptor
    complexes made of synthetic DNA by introducing a modelling framework and a dedicated
    experimental platform. In particular, we perform Monte Carlo simulations that
    combine a coarse grained description of the lipid bilayer with state of art analytical
    models for multivalent ligand–receptor interactions. Using density of state calculations,
    we derive the partition function in pairs of vesicles and compute the number of
    ligand–receptor bonds as a function of temperature. Numerical results are compared
    to microscopy and fluorimetry experiments on large unilamellar vesicles decorated
    by DNA linkers carrying complementary overhangs. We find that vesicle aggregation
    is suppressed when the total number of linkers falls below a threshold value.
    Within the model proposed here, this is due to the higher configurational costs
    required to form inter-vesicle bridges as compared to intra-vesicle loops, which
    are in turn related to membrane deformability. Our findings and our numerical/experimental
    methodologies are applicable to the rational design of liposomes used as functional
    materials and drug delivery applications, as well as to study inter-membrane interactions
    in living systems, such as cell adhesion.

  text: Far-field super-resolution fluorescence microscopy discerns fluorophores residing
    closer than the diffraction barrier by briefly transferring them in different
    (typically ON and OFF) states before detection. In coordinate-targeted super-resolution
    variants, such as stimulated emission depletion (STED) microscopy, this state
    difference is created by the intensity minima and maxima of an optical pattern,
    causing all fluorophores to assume the off state, for instance, except at the
    minima. Although strong spatial confinement of the on state enables high resolution,
    it also subjects the fluorophores to excess intensities and state cycles at the
    maxima. Here, we address these issues by driving the fluorophores into a second
    off state that is inert to the excess light. By using reversibly switchable fluorescent
    proteins as labels, our approach reduces bleaching and enhances resolution and
    contrast in live-cell STED microscopy. Using two or more transitions to off states
    is a useful strategy for augmenting the power of coordinate-targeted super-resolution
    microscopy.

  text: A range of bright and photostable rhodamines and carbopyronines with absorption
    maxima in the range of λ=500-630 nm were prepared, and enabled the specific labeling
    of cytoskeletal filaments using HaloTag technology followed by staining with 1
    μm solutions of the dye-ligand conjugates. The synthesis, photophysical parameters,
    fluorogenic behavior, and structure-property relationships of the new dyes are
    discussed. Light microscopy with stimulated emission depletion (STED) provided
    one- and two-color images of living cells with an optical resolution of 40-60
    nm.

  text: Superresolution fluorescence microscopy of multiple fluorophores still requires
    development. Here we present simultaneous three-colour stimulated emission depletion
    (STED) nanoscopy relying on a single STED beam at 620 nm. Toggling the STED beam
    between two or more power levels (&quot;multilevelSTEDv) optimizes resolution
    and contrast in all colour channels, which are intrinsically co-aligned and well
    separated. Three-colour recording is demonstrated by imaging the nanoscale cytoskeletal
    organization in cultured hippocampal neurons. The down to ∼35 nm resolution identified
    periodic actin/betaII spectrin lattices along dendrites and spines; however, at
    presynaptic and postsynaptic sites, these patterns were found to be absent. Both
    our multicolour scheme and the 620 nm STED line should be attractive for routine
    STED microscopy applications.

  text: 'Games on graphs provide the appropriate framework to study several central
    problems in computer science, such as verification and synthesis of reactive systems.
    One of the most basic objectives for games on graphs is the liveness (or Büchi)
    objective that given a target set of vertices requires that some vertex in the
    target set is visited infinitely often. We study generalized Büchi objectives
    (i.e., conjunction of liveness objectives), and implications between two generalized
    Büchi objectives (known as GR(1) objectives), that arise in numerous applications
    in computer-aided verification. We present improved algorithms and conditional
    super-linear lower bounds based on widely believed assumptions about the complexity
    of (A1) combinatorial Boolean matrix multiplication and (A2) CNF-SAT. We consider
    graph games with n vertices, m edges, and generalized Büchi objectives with k
    conjunctions. First, we present an algorithm with running time O(k*n^2), improving
    the previously known O(k*n*m) and O(k^2*n^2) worst-case bounds. Our algorithm
    is optimal for dense graphs under (A1). Second, we show that the basic algorithm
    for the problem is optimal for sparse graphs when the target sets have constant
    size under (A2). Finally, we consider GR(1) objectives, with k_1 conjunctions
    in the antecedent and k_2 conjunctions in the consequent, and present an O(k_1
    k_2 n^{2.5})-time algorithm, improving the previously known O(k_1*k_2*n*m)-time
    algorithm for m &gt; n^{1.5}. '

  text: "The Continuous Skolem Problem asks whether a real-valued function satisfying
    a linear differen-\r\ntial equation has a zero in a given interval of real numbers.
    This is a fundamental reachability\r\nproblem for continuous linear dynamical
    systems, such as linear hybrid automata and continuous-\r\ntime Markov chains.
    Decidability of the problem is currently open – indeed decidability is open\r\neven
    for the sub-problem in which a zero is sought in a bounded interval. In this paper
    we show\r\ndecidability of the bounded problem subject to Schanuel’s Conjecture,
    a unifying conjecture in\r\ntranscendental number theory. We furthermore analyse
    the unbounded problem in terms of the\r\nfrequencies of the differential equation,
    that is, the imaginary parts of the characteristic roots.\r\nWe show that the
    unbounded problem can be reduced to the bounded problem if there is at most\r\none
    rationally linearly independent frequency, or if there are two rationally linearly
    independent\r\nfrequencies and all characteristic roots are simple. We complete
    the picture by showing that de-\r\ncidability of the unbounded problem in the
    case of two (or more) rationally linearly independent\r\nfrequencies would entail
    a major new effectiveness result in Diophantine approximation, namely\r\ncomputability
    of the Diophantine-approximation types of all real algebraic numbers."

  text: 'We present a logic that extends CTL (Computation Tree Logic) with operators
    that express synchronization properties. A property is synchronized in a system
    if it holds in all paths of a certain length. The new logic is obtained by using
    the same path quantifiers and temporal operators as in CTL, but allowing a different
    order of the quantifiers. This small syntactic variation induces a logic that
    can express non-regular properties for which known extensions of MSO with equality
    of path length are undecidable. We show that our variant of CTL is decidable and
    that the model-checking problem is in Delta_3^P = P^{NP^NP}, and is DP-hard. We
    analogously consider quantifier exchange in extensions of CTL, and we present
    operators defined using basic operators of CTL* that express the occurrence of
    infinitely many synchronization points. We show that the model-checking problem
    remains in Delta_3^P. The distinguishing power of CTL and of our new logic coincide
    if the Next operator is allowed in the logics, thus the classical bisimulation
    quotient can be used for state-space reduction before model checking. '
