  text: Fractionation of isotopes among distinct molecules or phases is a quantum
    effect which is often exploited to obtain insights on reaction mechanisms, biochemical,
    geochemical, and atmospheric phenomena. Accurate evaluation of isotope ratios
    in atomistic simulations is challenging, because one needs to perform a thermodynamic
    integration with respect to the isotope mass, along with time-consuming path integral
    calculations. By re-formulating the problem as a particle exchange in the ring
    polymer partition function, we derive new estimators giving direct access to the
    differential partitioning of isotopes, which can simplify the calculations by
    avoiding thermodynamic integration. We demonstrate the efficiency of these estimators
    by applying them to investigate the isotope fractionation ratios in the gas-phase
    Zundel cation, and in a few simple hydrocarbons.

  text: It is well known that ultrasonic vibration can soften metals, and this phenomenon
    has been widely exploited in industrial applications concerning metal forming
    and bonding. Recent experiments show that the simultaneous application of oscillatory
    stresses from audible to ultrasonic frequency ranges can lead to not only softening
    but also significant dislocation annihilation and subgrain formation in metal
    samples from the nano- to macro-size range. These findings indicate that the existing
    understanding of ultrasound softening – that the vibrations either impose additional
    stress waves to augment the quasi-static applied load, or cause heating of the
    metal, whereas the metal’s intrinsic deformation resistance or mechanism remains
    unaltered – is far from complete. To understand the softening and the associated
    enhanced subgrain formation and dislocation annihilation, a new simulator based
    on the dynamics of dislocation-density functions is employed. This new simulator
    considers the flux, production and annihilation, as well as the Taylor and elastic
    interactions between dislocation densities. Softening during vibrations as well
    as enhanced cell formation is predicted. The simulations reveal the main mechanism
    for subcell formation under oscillatory loadings to be the enhanced elimination
    of statistically stored dislocations (SSDs) by the oscillatory stress, leaving
    behind geometrically necessary dislocations with low Schmid factors which then
    form the subgrain walls. The oscillatory stress helps the depletion of the SSDs,
    because the chance for them to meet up and annihilate is increased with reversals
    of dislocation motions. This is the first simulation effort to successfully predict
    the cell formation phenomenon under vibratory loadings.

  text: The distribution of Coulomb blockade peak heights as a function of magnetic
    field is investigated experimentally in a Ge-Si nanowire quantum dot. Strong spin-orbit
    coupling in this hole-gas system leads to antilocalization of Coulomb blockade
    peaks, consistent with theory. In particular, the peak height distribution has
    its maximum away from zero at zero magnetic field, with an average that decreases
    with increasing field. Magnetoconductance in the open-wire regime places a bound
    on the spin-orbit length (lso < 20 nm), consistent with values extracted in the
    Coulomb blockade regime (lso < 25 nm).

  text: The fitness effects of symbionts on their hosts can be context-dependent,
    with usually benign symbionts causing detrimental effects when their hosts are
    stressed, or typically parasitic symbionts providing protection towards their
    hosts (e.g. against pathogen infection). Here, we studied the novel association
    between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia
    formicarum for potential costs and benefits. We tested ants with different Laboulbenia
    levels for their survival and immunity under resource limitation and exposure
    to the obligate killing entomopathogen Metarhizium brunneum. While survival of
    L. neglectus workers under starvation was significantly decreased with increasing
    Laboulbenia levels, host survival under Metarhizium exposure increased with higher
    levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection,
    which seems to be driven mechanistically by both improved sanitary behaviours
    and an upregulated immune system. Ants with high Laboulbenia levels showed significantly
    longer self-grooming and elevated expression of immune genes relevant for wound
    repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase),
    compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont
    Laboulbenia formicarum weakens its ant host by either direct resource exploitation
    or the costs of an upregulated behavioural and immunological response, which,
    however, provides a prophylactic protection upon later exposure to pathogens.

  text: In rapidly changing environments, selection history may impact the dynamics
    of adaptation. Mutations selected in one environment may result in pleiotropic
    fitness trade-offs in subsequent novel environments, slowing the rates of adaptation.
    Epistatic interactions between mutations selected in sequential stressful environments
    may slow or accelerate subsequent rates of adaptation, depending on the nature
    of that interaction. We explored the dynamics of adaptation during sequential
    exposure to herbicides with different modes of action in Chlamydomonas reinhardtii.
    Evolution of resistance to two of the herbicides was largely independent of selection
    history. For carbetamide, previous adaptation to other herbicide modes of action
    positively impacted the likelihood of adaptation to this herbicide. Furthermore,
    while adaptation to all individual herbicides was associated with pleiotropic
    fitness costs in stress-free environments, we observed that accumulation of resistance
    mechanisms was accompanied by a reduction in overall fitness costs. We suggest
    that antagonistic epistasis may be a driving mechanism that enables populations
    to more readily adapt in novel environments. These findings highlight the potential
    for sequences of xenobiotics to facilitate the rapid evolution of multiple-drug
    and -pesticide resistance, as well as the potential for epistatic interactions
    between adaptive mutations to facilitate evolutionary rescue in rapidly changing
    environments.

  text: Understanding the effects of sex and migration on adaptation to novel environments
    remains a key problem in evolutionary biology. Using a single-cell alga Chlamydomonas
    reinhardtii, we investigated how sex and migration affected rates of evolutionary
    rescue in a sink environment, and subsequent changes in fitness following evolutionary
    rescue. We show that sex and migration affect both the rate of evolutionary rescue
    and subsequent adaptation. However, their combined effects change as the populations
    adapt to a sink habitat. Both sex and migration independently increased rates
    of evolutionary rescue, but the effect of sex on subsequent fitness improvements,
    following initial rescue, changed with migration, as sex was beneficial in the
    absence of migration but constraining adaptation when combined with migration.
    These results suggest that sex and migration are beneficial during the initial
    stages of adaptation, but can become detrimental as the population adapts to its
    environment.

  text: Redundancies and correlations in the responses of sensory neurons may seem
    to waste neural resources, but they can also carry cues about structured stimuli
    and may help the brain to correct for response errors. To investigate the effect
    of stimulus structure on redundancy in retina, we measured simultaneous responses
    from populations of retinal ganglion cells presented with natural and artificial
    stimuli that varied greatly in correlation structure; these stimuli and recordings
    are publicly available online. Responding to spatio-temporally structured stimuli
    such as natural movies, pairs of ganglion cells were modestly more correlated
    than in response to white noise checkerboards, but they were much less correlated
    than predicted by a non-adapting functional model of retinal response. Meanwhile,
    responding to stimuli with purely spatial correlations, pairs of ganglion cells
    showed increased correlations consistent with a static, non-adapting receptive
    field and nonlinearity. We found that in response to spatio-temporally correlated
    stimuli, ganglion cells had faster temporal kernels and tended to have stronger
    surrounds. These properties of individual cells, along with gain changes that
    opposed changes in effective contrast at the ganglion cell input, largely explained
    the pattern of pairwise correlations across stimuli where receptive field measurements
    were possible.

  text: 'Background: The brood of ants and other social insects is highly susceptible
    to pathogens, particularly those that penetrate the soft larval and pupal cuticle.
    We here test whether the presence of a pupal cocoon, which occurs in some ant
    species but not in others, affects the sanitary brood care and fungal infection
    patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We
    use a) a comparative approach analysing four species with either naked or cocooned
    pupae and b) a within-species analysis of a single ant species, in which both
    pupal types co-exist in the same colony. Results: We found that the presence of
    a cocoon did not compromise fungal pathogen detection by the ants and that species
    with cocooned pupae increased brood grooming after pathogen exposure. All tested
    ant species further removed brood from their nests, which was predominantly expressed
    towards larvae and naked pupae treated with the live fungal pathogen. In contrast,
    cocooned pupae exposed to live fungus were not removed at higher rates than cocooned
    pupae exposed to dead fungus or a sham control. Consistent with this, exposure
    to the live fungus caused high numbers of infections and fungal outgrowth in larvae
    and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed
    the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion:
    Our study suggests that the pupal cocoon has a protective effect against fungal
    infection, causing an adaptive change in sanitary behaviours by the ants. It further
    demonstrates that brood removal - originally described for honeybees as “hygienic
    behaviour” – is a widespread sanitary behaviour in ants, which likely has important
    implications on disease dynamics in social insect colonies.'

  text: We propose a method for detecting many-body localization (MBL) in disordered
    spin systems. The method involves pulsed coherent spin manipulations that probe
    the dephasing of a given spin due to its entanglement with a set of distant spins.
    It allows one to distinguish the MBL phase from a noninteracting localized phase
    and a delocalized phase. In particular, we show that for a properly chosen pulse
    sequence the MBL phase exhibits a characteristic power-law decay reflecting its
    slow growth of entanglement. We find that this power-law decay is robust with
    respect to thermal and disorder averaging, provide numerical simulations supporting
    our results, and discuss possible experimental realizations in solid-state and
    cold-atom systems.

  text: The newly discovered topological crystalline insulators feature a complex
    band structure involving multiple Dirac cones, and are potentially highly tunable
    by external electric field, temperature or strain. Theoretically, it has been
    predicted that the various Dirac cones, which are offset in energy and momentum,
    might harbour vastly different orbital character. However, their orbital texture,
    which is of immense importance in determining a variety of a materialâ €™ s properties
    remains elusive. Here, we unveil the orbital texture of Pb 1â ̂'x Sn x Se, a prototypical
    topological crystalline insulator. By using Fourier-transform scanning tunnelling
    spectroscopy we measure the interference patterns produced by the scattering of
    surface-state electrons. We discover that the intensity and energy dependences
    of the Fourier transforms show distinct characteristics, which can be directly
    attributed to orbital effects. Our experiments reveal a complex band topology
    involving two Lifshitz transitions and establish the orbital nature of the Dirac
    bands, which could provide an alternative pathway towards future quantum applications.

  text: In the recently discovered topological crystalline insulators SnTe and Pb1-xSnx(Te,
    Se), crystal symmetry and electronic topology intertwine to create topological
    surface states with many interesting features including Lifshitz transition, Van-Hove
    singularity, and fermion mass generation. These surface states are protected by
    mirror symmetry with respect to the (110) plane. In this work we present a comprehensive
    study of the effects of different mirror-symmetry-breaking perturbations on the
    (001) surface band structure. Pristine (001) surface states have four branches
    of Dirac fermions at low energy. We show that ferroelectric-type structural distortion
    generates a mass and gaps out some or all of these Dirac points, while strain
    shifts Dirac points in the Brillouin zone. An in-plane magnetic field leaves the
    surface state gapless, but introduces asymmetry between Dirac points. Finally,
    an out-of-plane magnetic field leads to discrete Landau levels. We show that the
    Landau level spectrum has an unusual pattern of degeneracy and interesting features
    due to the unique underlying band structure. This suggests that Landau level spectroscopy
    can detect and distinguish between different mechanisms of symmetry breaking in
    topological crystalline insulators.

  text: Relaxation and dephasing of hole spins are measured in a gate-defined Ge/Si
    nanowire double quantum dot using a fast pulsed-gate method and dispersive readout.
    An inhomogeneous dephasing time T2* ∼ 0.18 μs exceeds corresponding measurements
    in III-V semiconductors by more than an order of magnitude, as expected for predominately
    nuclear-spin-free materials. Dephasing is observed to be exponential in time,
    indicating the presence of a broadband noise source, rather than Gaussian, previously
    seen in systems with nuclear-spin-dominated dephasing.

  text: Many-body localized (MBL) systems are characterized by the absence of transport
    and thermalization and, therefore, cannot be described by conventional statistical
    mechanics. In this paper, using analytic arguments and numerical simulations,
    we study the behavior of local observables in an isolated MBL system following
    a quantum quench. For the case of a global quench, we find that the local observables
    reach stationary, highly nonthermal values at long times as a result of slow dephasing
    characteristic of the MBL phase. These stationary values retain the local memory
    of the initial state due to the existence of local integrals of motion in the
    MBL phase. The temporal fluctuations around stationary values exhibit universal
    power-law decay in time, with an exponent set by the localization length and the
    diagonal entropy of the initial state. Such a power-law decay holds for any local
    observable and is related to the logarithmic in time growth of entanglement in
    the MBL phase. This behavior distinguishes the MBL phase from both the Anderson
    insulator (where no stationary state is reached) and from the ergodic phase (where
    relaxation is expected to be exponential). For the case of a local quench, we
    also find a power-law approach of local observables to their stationary values
    when the system is prepared in a mixed state. Quench protocols considered in this
    paper can be naturally implemented in systems of ultracold atoms in disordered
    optical lattices, and the behavior of local observables provides a direct experimental
    signature of many-body localization.

  text: 'We explore the relationship between polar and RM codes and we describe a
    coding scheme which improves upon the performance of the standard polar code at
    practical block lengths. Our starting point is the experimental observation that
    RM codes have a smaller error probability than polar codes under MAP decoding.
    This motivates us to introduce a family of codes that “interpolates” between RM
    and polar codes, call this family C inter = {C α : α ∈ [0, 1j}, where C α|α=1
    is the original polar code, and C α|α=0 is an RM code. Based on numerical observations,
    we remark that the error probability under MAP decoding is an increasing function
    of α. MAP decoding has in general exponential complexity, but empirically the
    performance of polar codes at finite block lengths is boosted by moving along
    the family Cinter even under low-complexity decoding schemes such as, for instance,
    belief propagation or successive cancellation list decoder. We demonstrate the
    performance gain via numerical simulations for transmission over the erasure channel
    as well as the Gaussian channel.'

  text: We describe coding techniques that achieve the capacity of a discrete memoryless
    asymmetric channel. To do so, we discuss how recent advances in coding for symmetric
    channels yield more efficient solutions also for the asymmetric case. In more
    detail, we consider three basic approaches. The first one is Gallager's scheme
    that concatenates a linear code with a non-linear mapper, in order to bias the
    input distribution. We explicitly show that both polar codes and spatially coupled
    codes can be employed in this scenario. Further, we derive a scaling law between
    the gap to capacity, the cardinality of channel input and output alphabets, and
    the required size of the mapper. The second one is an integrated approach in which
    the coding scheme is used both for source coding, in order to create codewords
    with the capacity-achieving distribution, and for channel coding, in order to
    provide error protection. Such a technique has been recently introduced by Honda
    and Yamamoto in the context of polar codes, and we show how to apply it also to
    the design of sparse graph codes. The third approach is based on an idea due to
    Böcherer and Mathar and separates completely the two tasks of source coding and
    channel coding by “chaining” together several codewords. We prove that we can
    combine any suitable source code with any suitable channel code in order to provide
    optimal schemes for asymmetric channels. In particular, polar codes and spatially
    coupled codes fulfill the required conditions.

  text: With the aim of extending the coverage and improving the performance of impulse
    radio ultra-wideband (UWB) systems, this paper focuses on developing a novel single
    differential encoded decode and forward (DF) non-cooperative relaying scheme (NCR).
    To favor simple receiver structures, differential noncoherent detection is employed
    which enables effective energy capture without any channel estimation. Putting
    emphasis on the general case of multi-hop relaying, we illustrate an original
    algorithm for the joint power allocation and path selection (JPAPS), minimizing
    an approximate expression of the overall bit error rate (BER). In particular,
    after deriving a closed-form power allocation strategy, the optimal path selection
    is reduced to a shortest path problem on a connected graph, which can be solved
    without any topology information with complexity O(N 3 ), N being the number of
    available relays of the network. An approximate scheme is also presented, which
    reduces the complexity to O(N 2 ) while showing a negligible performance loss,
    and for benchmarking purposes, an exhaustive-search based multi-hop DF cooperative
    strategy is derived. Simulation results for various network setups corroborate
    the effectiveness of the proposed low-complexity JPAPS algorithm, which favorably
    compares to existing AF and DF relaying methods.

  text: This monograph presents a short course in computational geometry and topology.
    In the first part the book covers Voronoi diagrams and Delaunay triangulations,
    then it presents the theory of alpha complexes which play a crucial role in biology.
    The central part of the book is the homology theory and their computation, including
    the theory of persistence which is indispensable for applications, e.g. shape
    reconstruction. The target audience comprises researchers and practitioners in
    mathematics, biology, neuroscience and computer science, but the book may also
    be beneficial to graduate students of these fields.
