  text: We investigate the low energy excitation spectrum of a Bose gas with weak,
    long range repulsive interactions. In particular, we prove that the Bogoliubov
    spectrum of elementary excitations with linear dispersion relation for small momentum
    becomes exact in the mean-field limit.

  text: 'Let EMBEDk→d be the following algorithmic problem: Given a finite simplicial
    complex K of dimension at most k, does there exist a (piecewise linear) embedding
    of K into Rd? Known results easily imply the polynomiality of EMBEDk→2 (k = 1;
    2; the case k = 1, d = 2 is graph planarity) and of EMBEDk→2k for all k ≥ 3. We
    show that the celebrated result of Novikov on the algorithmic unsolvability of
    recognizing the 5-sphere implies that EMBEDd→d and EMBED (d-1)→d are undecidable
    for each d ≥ 5. Our main result is the NP-hardness of EMBED2→4 and, more generally,
    of EMBED k→d for all k; d with d ≥ 4 and d ≥ k ≥ (2d - 2)/3. These dimensions
    fall outside the metastable range of a theorem of Haefliger and Weber, which characterizes
    embeddability using the deleted product obstruction. Our reductions are based
    on examples, due to Segal, Spież, Freedman, Krushkal, Teichner, and Skopenkov,
    showing that outside the metastable range the deleted product obstruction is not
    sufficient to characterize embeddability. '

  text: We introduce a new notion of minors for simplicial complexes (hypergraphs),
    so-called homological minors. Our motivation is to propose a general approach
    to attack certain extremal problems for sparse simplicial complexes and the corresponding
    threshold problems for random complexes. In this paper, we focus on threshold
    problems. The basic model for random complexes is the Linial-Meshulam model Xk(n,
    p). By definition, such a complex has n vertices, a complete (k -1)-dimensional
    skeleton, and every possible k-dimensional simplex is chosen independently with
    probability p. We show that for every k, t≥ 1, there is a constant C = C(k, t)
    such that for p≥ C/n, the random complex Xk(n, p) asymptotically almost surely
    contains K tk (the complete k-dimensional complex on t vertices) as a homological
    minor. As corollary, the threshold for (topological) embeddability of Xk(n, p)
    into R2k is at p = θ(1/n). The method can be extended to other models of random
    complexes (for which the lower skeleta are not necessarily complete) and also
    to more general Tverberg-type problems, where instead of continuous maps without
    doubly covered image points (embeddings), we consider maps without qfold covered
    image points.

  text: Within a multicellular tissue cells may coordinately form a singular or multiple
    polar axes, but it is unclear whether a common mechanism governs different types
    of polar axis formation. The phosphorylation status of PIN proteins, which is
    directly affected by the PINOID (PID) protein kinase and the PP2A protein phosphatase,
    is known to regulate the apical-basal polarity of PIN localization in bipolar
    cells of roots and shoot apices. Here, we provide evidence that the phosphorylation
    status-mediated PIN polarity switch is widely used to modulate cellular processes
    in Arabidopsis including multipolar pavement cells (PC) with interdigitated lobes
    and indentations. The degree of PC interdigitation was greatly reduced either
    when the FYPP1 gene, which encodes a PP2A called phytochrome-associated serine/threonine
    protein phosphatase, was knocked out or when the PID gene was overexpressed (35S:PID).
    These genetic modifications caused PIN1 localization to switch from lobe to indentation
    regions. The PP2A and PID mediated switching of PIN1 localization is strikingly
    similar to their regulation of the apical-basal polarity switch of PIN proteins
    in other cells. Our findings suggest a common mechanism for the regulation of
    PIN1 polarity formation, a fundamental cellular process that is crucial for pattern
    formation both at the tissue/organ and cellular levels.

  text: In unicellular and multicellular organisms, cell polarity is essential for
    a wide range of biological processes. An important feature of cell polarity is
    the asymmetric distribution of proteins in or at the plasma membrane. In plants
    such polar localized proteins play various specific roles ranging from organizing
    cell morphogenesis, asymmetric cell division, pathogen defense, nutrient transport
    and establishment of hormone gradients for developmental patterning. Moreover,
    flexible respecification of cell polarities enables plants to adjust their physiology
    and development to environmental changes. Having evolved multicellularity independently
    and lacking major cell polarity mechanisms of animal cells, plants came up with
    alternative solutions to generate and respecify cell polarity as well as to regulate
    polar domains at the plasma membrane.

  text: Parkinson's disease is a common neurodegenerative disorder characterized by
    a profound motor disability that is traceable to the emergence of synchronous,
    rhythmic spiking in neurons of the external segment of the globus pallidus (GPe).
    The origins of this pathophysiology are poorly defined for the generation of pacemaking.
    After the induction of a parkinsonian state in mice, there was a progressive decline
    in autonomous GPe pacemaking, which normally serves to desynchronize activity.
    The loss was attributable to the downregulation of an ion channel that is essential
    in pacemaking, the hyperpolarization and cyclic nucleotide-gated (HCN) channel.
    Viral delivery of HCN2 subunits restored pacemaking and reduced burst spiking
    in GPe neurons. However, the motor disability induced by dopamine (DA) depletion
    was not reversed, suggesting that the loss of pacemaking was a consequence, rather
    than a cause, of key network pathophysiology, a conclusion that is consistent
    with the ability of L-type channel antagonists to attenuate silencing after DA
    depletion.

  text: GABAergic inhibition plays a central role in the control of pyramidal cell
    ensemble activities; thus, any signaling mechanism that regulates inhibition is
    able to fine-tune network patterns. Here, we provide evidence that the retrograde
    nitric oxide (NO)- cGMP cascade triggered by NMDA receptor (NMDAR) activation
    plays a role in the control of hippocampal GABAergic transmission in mice. GABAergic
    synapses express neuronal nitric oxide synthase (nNOS) postsynaptically and NO
    receptors (NO-sensitive guanylyl cyclase) in the presynaptic terminals. We hypothesized
    that-similar to glutamatergic synapses-the Ca 2+ transients required to activate
    nNOS were provided by NMDA receptor activation. Indeed, administration of 5 μm
    NMDA induced a robust nNOS-dependent cGMP production in GABAergic terminals, selectively
    in the CA1 and CA3c areas. Furthermore, using preembedding, postembedding, and
    SDS-digested freeze-fracture replica immunogold labeling, we provided quantitative
    immunocytochemical evidence that NMDAR subunits GluN1, GluN2A, and GluN2B were
    present in most somatic GABAergic synapses postsynaptically. These data indicate
    that NMDARs can modulate hippocampal GABAergic inhibition via NO- cGMP signaling
    in an activity-dependent manner and that this effect is subregion specific in
    the mouse hippocampus.

  text: 'SK2-containing channels are expressed in the postsynaptic density (PSD) of
    dendritic spines on mouse hippocampal area CA1 pyramidal neurons and influence
    synaptic responses, plasticity and learning. The Sk2 gene (also known as Kcnn2)
    encodes two isoforms that differ only in the length of their N-terminal domains.
    SK2-long (SK2-L) and SK2-short (SK2-S) are coexpressed in CA1 pyramidal neurons
    and likely form heteromeric channels. In mice lacking SK2-L (SK2-S only mice),
    SK2-S-containing channels were expressed in the extrasynaptic membrane, but were
    excluded from the PSD. The SK channel contribution to excitatory postsynaptic
    potentials was absent in SK2-S only mice and was restored by SK2-L re-expression.
    Blocking SK channels increased the amount of long-term potentiation induced in
    area CA1 in slices from wild-type mice but had no effect in slices from SK2-S
    only mice. Furthermore, SK2-S only mice outperformed wild-type mice in the novel
    object recognition task. These results indicate that SK2-L directs synaptic SK2-containing
    channel expression and is important for normal synaptic signaling, plasticity
    and learning. '

  text: The emergence of differences in the arrangement of cells is the first step
    towards the establishment of many organs. Understanding this process is limited
    by the lack of systematic characterization of epithelial organisation. Here we
    apply network theory at the scale of individual cells to uncover patterns in cell-to-cell
    contacts that govern epithelial organisation. We provide an objective characterisation
    of epithelia using network representation, where cells are nodes and cell contacts
    are links. The features of individual cells, together with attributes of the cellular
    network, produce a defining signature that distinguishes epithelia from different
    organs, species, developmental stages and genetic conditions. The approach permits
    characterization, quantification and classification of normal and perturbed epithelia,
    and establishes a framework for understanding molecular mechanisms that underpin
    the architecture of complex tissues.

  text: Morphogens, such as Decapentaplegic (Dpp) in the fly imaginal discs, form
    graded concentration profiles that control patterning and growth of developing
    organs. In the imaginal discs, proliferative growth is homogeneous in space, posing
    the conundrum of how morphogen concentration gradients could control position-independent
    growth. To understand the mechanism of proliferation control by the Dpp gradient,
    we quantified Dpp concentration and signaling levels during wing disc growth.
    Both Dpp concentration and signaling gradients scale with tissue size during development.
    On average, cells divide when Dpp signaling levels have increased by 50%. Our
    observations are consistent with a growth control mechanism based on temporal
    changes of cellular morphogen signaling levels. For a scaling gradient, this mechanism
    generates position-independent growth rates.

  text: 'We report on a technique enabling electrical control of the contact silicidation
    process in silicon nanowire devices. Undoped silicon nanowires were contacted
    by pairs of nickel electrodes and each contact was selectively silicided by means
    of the Joule effect. By a realtime monitoring of the nanowire electrical resistance
    during the contact silicidation process we were able to fabricate nickel-silicide/silicon/nickel-
    silicide devices with controlled silicon channel length down to 8 nm. '

  text: Spin-selective tunneling of holes in SiGe nanocrystals contacted by normal-metal
    leads is reported. The spin selectivity arises from an interplay of the orbital
    effect of the magnetic field with the strong spin-orbit interaction present in
    the valence band of the semiconductor. We demonstrate both experimentally and
    theoretically that spin-selective tunneling in semiconductor nanostructures can
    be achieved without the use of ferromagnetic contacts. The reported effect, which
    relies on mixing the light and heavy holes, should be observable in a broad class
    of quantum-dot systems formed in semiconductors with a degenerate valence band.

  text: We study the effects of a thin gaseous accretion disk on the inspiral of a
    stellar--mass black hole into a supermassive black hole. We construct a phenomenological
    angular momentum transport equation that reproduces known disk effects. Disk torques
    modify the gravitational wave phase evolution to detectable levels with LISA for
    reasonable disk parameters. The Fourier transform of disk-modified waveforms acquires
    a correction with a different frequency trend than post-Newtonian vacuum terms.
    Such inspirals could be used to detect accretion disks with LISA and to probe
    their physical parameters.

  text: Recent studies have shown that the number counts of convergence peaks N(kappa)
    in weak lensing (WL) maps, expected from large forthcoming surveys, can be a useful
    probe of cosmology. We follow up on this finding, and use a suite of WL convergence
    maps, obtained from ray-tracing N-body simulations, to study (i) the physical
    origin of WL peaks with different heights, and (ii) whether the peaks contain
    information beyond the convergence power spectrum P_ell. In agreement with earlier
    work, we find that high peaks (with amplitudes >~ 3.5 sigma, where sigma is the
    r.m.s. of the convergence kappa) are typically dominated by a single massive halo.
    In contrast, medium-height peaks (~0.5-1.5 sigma) cannot be attributed to a single
    collapsed dark matter halo, and are instead created by the projection of multiple
    (typically, 4-8) halos along the line of sight, and by random galaxy shape noise.
    Nevertheless, these peaks dominate the sensitivity to the cosmological parameters
    w, sigma_8, and Omega_m. We find that the peak height distribution and its dependence
    on cosmology differ significantly from predictions in a Gaussian random field.
    We directly compute the marginalized errors on w, sigma_8, and Omega_m from the
    N(kappa) + P_ell combination, including redshift tomography with source galaxies
    at z_s=1 and z_s=2. We find that the N(kappa) + P_ell combination has approximately
    twice the cosmological sensitivity compared to P_ell alone. These results demonstrate
    that N(kappa) contains non-Gaussian information complementary to the power spectrum.

  text: It has been shown that HD molecules can form efficiently in metal-free gas
    collapsing into massive protogalactic halos at high redshift. The resulting radiative
    cooling by HD can lower the gas temperature to that of the cosmic microwave background,
    T_CMB=2.7(1+z)K, significantly below the temperature of a few 100 K achievable
    via H_2-cooling alone, and thus reduce the masses of the first generation of stars.
    Here we consider the suppression of HD-cooling by UV irradiation in the Lyman-Werner
    (LW) bands. We include photo-dissociation of both H_2 and HD, and explicitly compute
    the self-shielding and shielding of both molecules by neutral hydrogen as well
    as the shielding of HD by H_2. We use a simplified dynamical collapse model, and
    follow the chemical and thermal evolution of the gas, in the presence of a UV
    background. We find that a LW flux of J_crit = 1e-22 erg/cm^2/sr/s/Hz is able
    to suppress HD cooling and thus prevent collapsing primordial gas from reaching
    temperatures below 100 K. The main reason for the lack of HD cooling for J>J_crit
    is the partial photo-dissociation of H_2, which prevents the gas from reaching
    sufficiently low temperatures (T<150K) for HD to become the dominant coolant;
    direct HD photo-dissociation is unimportant except for a narrow range of fluxes
    and column densities. Since the prevention of HD-cooling requires only partial
    H_2 photo-dissociation, the critical flux J_crit is modest, and is below the UV
    background required to reionize the universe at redshift z=10-20. We conclude
    that HD-cooling can reduce the masses of typical stars only in rare halos forming
    well before the epoch of reionization.

  text: The gravitational waves (GWs) emitted by inspiralling binary black holes,
    expected to be detected by the Laser Interferometer Space Antenna (LISA), could
    be used to determine the luminosity distance to these sources with the unprecedented
    precision of ≲1 per cent. We study cosmological parameter constraints from such
    standard sirens, in the presence of gravitational lensing by large-scale structure.
    Lensing introduces magnification with a probability distribution function (PDF)
    whose shape has significant skewness and kurtosis, and depends on cosmological
    parameters. We use Monte Carlo simulations to generate mock samples of standard
    sirens, including a small intrinsic scatter, as well as the additional, larger
    scatter from lensing, in their inferred distances. We derive constraints on cosmological
    parameters, by simultaneously fitting the mean and the distribution of the residuals
    on the distance versus redshift (dL–z) Hubble diagram. We find that for standard
    sirens at redshift z≈ 1, the sensitivity to a single cosmological parameter, such
    as the matter density Ωm, or the dark energy equation of state w, is ∼50–80 per
    cent tighter when the lensing PDF is used, compared to the sensitivity derived
    from a Gaussian PDF with the same variance. When these two parameters are constrained
    simultaneously, the non-Gaussian shape yields a further enhanced improvement (by
    ∼120 per cent), owing to the correlation between the parameters. The sensitivity
    to the amplitude of the matter power spectrum, σ8 from the cosmological dependence
    of the PDF alone, however, is ∼20 per cent worse than that from the Gaussian PDF.
    The improvements for Ωm and w arise purely from the non-Gaussian shape of the
    lensing PDF and can be attributed specifically to the sharpness of the peak of
    this PDF (i.e. to a finite kurtosis); the dependence of the PDF on these parameters
    does not improve constraints relative to those available from the mean dL–z relation.
    At higher redshifts, the PDF resembles a Gaussian more closely, and the effects
    of the non-Gaussianities become less prominent. These results highlight the importance
    of obtaining an accurate and reliable PDF of the lensing convergence, in order
    to realize the full potential of standard sirens as cosmological probes.

  text: The ability of primordial gas to cool in proto-galactic haloes exposed to
    Lyman-Werner (LW) radiation is critically dependent on the self-shielding of H_2.
    We perform radiative transfer calculations of LW line photons, post-processing
    outputs from three-dimensional adaptive mesh refinement (AMR) simulations of haloes
    with T_vir > 10^4 K at redshifts around z=10. We calculate the optically thick
    photodissociation rate numerically, including the effects of density, temperature,
    and velocity gradients in the gas, as well as line overlap and shielding of H_2
    by HI, over a large number of sight-lines. In low-density regions (n<10^4 cm^-3)
    the dissociation rates exceed those obtained using most previous approximations
    by more than an order of magnitude; the correction is smaller at higher densities.
    We trace the origin of the deviations primarily to inaccuracies of (i) the most
    common fitting formula (Draine & Bertoldi 1996) for the suppression of the dissociation
    rate and (ii) estimates for the effective shielding column density from local
    properties of the gas. The combined effects of gas temperature and velocity gradients
    are comparatively less important, typically altering the spherically averaged
    rate only by a factor of less than two. We present a simple modification to the
    DB96 fitting formula for the optically thick rate which improves agreement with
    our numerical results to within approx. 15 per cent, and can be adopted in future
    simulations. We find that estimates for the effective shielding column can be
    improved by using the local Sobolev length. Our correction to the H_2 self-shielding
    reduces the critical LW flux to suppress H_2-cooling in T_vir>10^4 K haloes by
    an order of magnitude; this increases the number of such haloes in which supermassive
    (approx. M=10^5 M_sun) black holes may have formed.

  text: At optical frequencies the radiation produced by a source, such as a laser,
    a black body or a single-photon emitter, is frequently characterized by analysing
    the temporal correlations of emitted photons using single-photon counters. At
    microwave frequencies, however, there are no efficient single-photon counters
    yet. Instead, well-developed linear amplifiers allow for efficient measurement
    of the amplitude of an electromagnetic field. Here, we demonstrate first- and
    second-order correlation function measurements of a pulsed microwave-frequency
    single-photon source integrated on the same chip with a 50/50 beam splitter followed
    by linear amplifiers and quadrature amplitude detectors. We clearly observe single-photon
    coherence in first-order and photon antibunching in second-order correlation function
    measurements of the propagating fields.

  text: Superconducting circuits have been successfully established as systems to
    prepare and investigate microwave light fields at the quantum level. In contrast
    to optical experiments where light is detected using photon counters, microwaves
    are usually measured with well developed linear amplifiers. This makes measurements
    of correlation functions - one of the important tools in optics - harder to achieve
    because they traditionally rely on photon counters and beam splitters. Here, we
    demonstrate a system where we can prepare on demand single microwave photons in
    a cavity and detect them at the two outputs of the cavity using linear amplifiers.
    Together with efficient data processing, this allows us to measure different observables
    of the cavity photons, including the first-order correlation function. Using these
    techniques we demonstrate cooling of a thermal background field in the cavity.
