  text: Context-dependent adjustment of mating tactics can drastically increase the
    mating success of behaviourally flexible animals. We used the ant Cardiocondyla
    obscurior as a model system to study adaptive adjustment of male mating tactics.
    This species shows a male diphenism of wingless fighter males and peaceful winged
    males. Whereas the wingless males stay and exclusively mate in the maternal colony,
    the mating behaviour of winged males is plastic. They copulate with female sexuals
    in their natal nests early in life but later disperse in search for sexuals outside.
    In this study, we observed the nest-leaving behaviour of winged males under different
    conditions and found that they adaptively adjust the timing of their dispersal
    to the availability of mating partners, as well as the presence, and even the
    type of competitors in their natal nests. In colonies with virgin female queens
    winged males stayed longest when they were the only male in the nest. They left
    earlier when mating partners were not available or when other males were present.
    In the presence of wingless, locally mating fighter males, winged males dispersed
    earlier than in the presence of docile, winged competitors. This suggests that
    C. obscurior males are capable of estimating their local breeding chances and
    adaptively adjust their dispersal behaviour in both an opportunistic and a risk-sensitive
    way, thus showing hitherto unknown behavioural plasticity in social insect males.

  text: The Bicoid morphogen gradient directs the patterning of cell fates along the
    anterior-posterior axis of the syncytial Drosophila embryo and serves as a paradigm
    of morphogen-mediated patterning. The simplest models of gradient formation rely
    on constant protein synthesis and diffusion from anteriorly localized source mRNA,
    coupled with uniform protein degradation. However, currently such models cannot
    account for all known gradient characteristics. Recent work has proposed that
    bicoid mRNA spatial distribution is sufficient to produce the observed protein
    gradient, minimizing the role of protein transport. Here, we adapt a novel method
    of fluorescent in situ hybridization to quantify the global spatio-temporal dynamics
    of bicoid mRNA particles. We determine that &gt;90% of all bicoid mRNA is continuously
    present within the anterior 20% of the embryo. bicoid mRNA distribution along
    the body axis remains nearly unchanged despite dynamic mRNA translocation from
    the embryo core to the cortex. To evaluate the impact of mRNA distribution on
    protein gradient dynamics, we provide detailed quantitative measurements of nuclear
    Bicoid levels during the formation of the protein gradient. We find that gradient
    establishment begins 45 minutes after fertilization and that the gradient requires
    about 50 minutes to reach peak levels. In numerical simulations of gradient formation,
    we find that incorporating the actual bicoid mRNA distribution yields a closer
    prediction of the observed protein dynamics compared to modeling protein production
    from a point source at the anterior pole. We conclude that the spatial distribution
    of bicoid mRNA contributes to, but cannot account for, protein gradient formation,
    and therefore that protein movement, either active or passive, is required for
    gradient formation.

  text: Glutamate is the major excitatory neurotransmitter in the mammalian central
    nervous system and gates non-selective cation channels. The origins of glutamate
    receptors are not well understood as they differ structurally and functionally
    from simple bacterial ligand-gated ion channels. Here we report the discovery
    of an ionotropic glutamate receptor that combines the typical eukaryotic domain
    architecture with the 'TXVGYG' signature sequence of the selectivity filter found
    in K+ channels. This receptor exhibits functional properties intermediate between
    bacterial and eukaryotic glutamate-gated ion channels, suggesting a link in the
    evolution of ionotropic glutamate receptors.

  text: Understanding the mechanism of protein folding requires a detailed knowledge
    of the structural properties of the barriers separating unfolded from native conformations.
    The S-peptide from ribonuclease S forms its α-helical structure only upon binding
    to the folded S-protein. We characterized the transition state for this binding-induced
    folding reaction at high resolution by determining the effect of site-specific
    backbone thioxylation and side-chain modifications on the kinetics and thermodynamics
    of the reaction, which allows us to monitor formation of backbone hydrogen bonds
    and side-chain interactions in the transition state. The experiments reveal that
    α-helical structure in the S-peptide is absent in the transition state of binding.
    Recognition between the unfolded S-peptide and the S-protein is mediated by loosely
    packed hydrophobic side-chain interactions in two well defined regions on the
    S-peptide. Close packing and helix formation occurs rapidly after binding. Introducing
    hydrophobic residues at positions outside the recognition region can drastically
    slow down association.

  text: We propose a general conjecture for the mixed Hodge polynomial of the generic
    character varieties of representations of the fundamental group of a Riemann surface
    of genus g to GLn(C) with fixed generic semisimple conjugacy classes at k punctures.
    This conjecture generalizes the Cauchy identity for Macdonald polynomials and
    is a common generalization of two formulas that we prove in this paper. The first
    is a formula for the E-polynomial of these character varieties which we obtain
    using the character table of GLn(Fq). We use this formula to compute the Euler
    characteristic of character varieties. The second formula gives the Poincaré polynomial
    of certain associated quiver varieties which we obtain using the character table
    of gln(Fq). In the last main result we prove that the Poincaré polynomials of
    the quiver varieties equal certain multiplicities in the tensor product of irreducible
    characters of GLn(Fq). As a consequence we find a curious connection between Kac-Moody
    algebras associated with comet-shaped, and typically wild, quivers and the representation
    theory of GLn(Fq).

  text: Microwave cavities with high quality factors enable coherent coupling of distant
    quantum systems. Virtual photons lead to a transverse interaction between qubits
    when they are nonresonant with the cavity but resonant with each other. We experimentally
    investigate the inverse scaling of the interqubit coupling with the detuning from
    a cavity mode and its proportionality to the qubit-cavity interaction strength.
    We demonstrate that the enhanced coupling at higher frequencies is mediated by
    multiple higher-harmonic cavity modes. Moreover, we observe dark states of the
    coupled qubit-qubit system and analyze their relation to the symmetry of the applied
    driving field at different frequencies.

  text: We report the first concurrent determination of conductance (G) and thermopower
    (S) of single-molecule junctions via direct measurement of electrical and thermoelectric
    currents using a scanning tunneling microscope-based break-junction technique.
    We explore several amine-Au and pyridine-Au linked molecules that are predicted
    to conduct through either the highest occupied molecular orbital (HOMO) or the
    lowest unoccupied molecular orbital (LUMO), respectively. We find that the Seebeck
    coefficient is negative for pyridine-Au linked LUMO-conducting junctions and positive
    for amine-Au linked HOMO-conducting junctions. Within the accessible temperature
    gradients (<30 K), we do not observe a strong dependence of the junction Seebeck
    coefficient on temperature. From histograms of thousands of junctions, we use
    the most probable Seebeck coefficient to determine a power factor, GS2, for each
    junction studied, and find that GS2 increases with G. Finally, we find that conductance
    and Seebeck coefficient values are in good quantitative agreement with our self-energy
    corrected density functional theory calculations.

  text: We measure electronic conductance through single conjugated molecules bonded
    to Au metal electrodes with direct Au–C covalent bonds using the scanning tunneling
    microscope based break-junction technique. We start with molecules terminated
    with trimethyltin end groups that cleave off in situ, resulting in formation of
    a direct covalent σ bond between the carbon backbone and the gold metal electrodes.
    The molecular carbon backbone used in this study consist of a conjugated π system
    that has one terminal methylene group on each end, which bonds to the electrodes,
    achieving large electronic coupling of the electrodes to the π system. The junctions
    formed with the prototypical example of 1,4-dimethylenebenzene show a conductance
    approaching one conductance quantum (G0 = 2e2/h). Junctions formed with methylene-terminated
    oligophenyls with two to four phenyl units show a 100-fold increase in conductance
    compared with junctions formed with amine-linked oligophenyls. The conduction
    mechanism for these longer oligophenyls is tunneling, as they exhibit an exponential
    dependence of conductance on oligomer length. In addition, density functional
    theory based calculations for the Au–xylylene–Au junction show near-resonant transmission,
    with a crossover to tunneling for the longer oligomers.

  text: We investigate the binding and energy level alignment of 2,3,5,6-tetramethyl-1,4-benzenediamine
    (TMBDA) on Au(111) through a combination of helium atom scattering (HAS), X-ray
    photoemission (XPS), and scanning tunneling microscopy (STM). We show that TMBDA
    binds to step edges and to flat Au (111) terraces in a nearly flat-lying configuration.
    Through combination of HAS and STM data, we determine that the molecules are bound
    on step edges with an adsorption energy of about 1.2 eV, which is about 0.2 eV
    stronger than the adsorption energy we measure on flat surface. Preferential bonding
    to the under-coordinated Au atoms on step edges suggests that the molecules bind
    to Au through the nitrogen lone pair. Finally, STM measurements on TMBDA in these
    two different adsorption configurations show that the highest-occupied molecular
    orbital is deeper relative to Fermi for the more strongly bound molecules on step
    edges, confirming that the nitrogen bonds through charge donation to the Au.

  text: Understanding the electrical properties of semiconducting quantum dot devices
    have been limited due to the variability of their size/composition and the chemistry
    of ligand/electrode binding. Furthermore, to probe their electrical conduction
    properties and its dependence on ligand/electrode binding, measurements must be
    carried out at the single dot/cluster level. Herein we report scanning tunneling
    microscope based break junction measurements of cobalt chalcogenide clusters with
    Te, Se and S to probe the conductance properties. Our measured conductance trends
    show that the Co–Te based clusters have the highest conductance while the Co-S
    clusters the lowest. These trends are in very good agreement with cyclic voltammetry
    measurements of the first oxidation potentials and with density functional theory
    calculations of their HOMO–LUMO gaps.

  text: The conductance of individual 1,4-benzenediamine (BDA)–Au molecular junctions
    is measured in different solvent environments using a scanning tunneling microscope
    based point-contact technique. Solvents are found to increase the conductance
    of these molecular junctions by as much as 50%. Using first principles calculations,
    we explain this increase by showing that a shift in the Au contact work function
    is induced by solvents binding to undercoordinated Au sites around the junction.
    Increasing the Au contact work function reduces the separation between the Au
    Fermi energy and the highest occupied molecular orbital of BDA in the junction,
    increasing the measured conductance. We demonstrate that the solvent-induced shift
    in conductance depends on the affinity of the solvent to Au binding sites and
    also on the induced dipole (relative to BDA) upon adsorption. Via this mechanism,
    molecular junction level alignment and transport properties can be statistically
    altered by solvent molecule binding to the contact surface.

  text: Controlling electron transport through a single-molecule device is key to
    the realization of nanoscale electronic components. A design requirement for single
    molecule electrical devices is that the molecule must be both structurally and
    electrically connected to the metallic electrodes. Typically, the mechanical and
    electrical contacts are achieved by the same chemical moiety. In this study, we
    demonstrate that the structural role may be played by one group (for example,
    a sulfide) while the electrical role may be played by another (a conjugated chain
    of C═C π-bonds). We can specify the electrical conductance through the molecule
    by modulating to which particular site on the oligoene chain the electrode binds.
    The result is a device that functions as a potentiometer at the single-molecule
    level.

  text: We simultaneously measure conductance and force across nanoscale junctions.
    A new, two-dimensional histogram technique is introduced to statistically extract
    bond rupture forces from a large data set of individual junction elongation traces.
    For the case of Au point contacts, we find a rupture force of 1.4 ± 0.2 nN, which
    is in good agreement with previous measurements. We then study systematic trends
    for single gold metal−molecule−metal junctions for a series of molecules terminated
    with amine and pyridine linkers. For all molecules studied, single molecule junctions
    rupture at the Au−N bond. Selective binding of the linker group allows us to correlate
    the N−Au bond-rupture force to the molecular backbone. We find that the rupture
    force ranges from 0.8 nN for 4,4′ bipyridine to 0.5 nN in 1,4 diaminobenzene.
    These experimental results are in excellent quantitative agreement with density
    functional theory based adiabatic molecular junction elongation and rupture calculations.

  text: Understanding electron transport across π−π-stacked systems will help to answer
    fundamental questions about biochemical redox processes and benefit the design
    of new materials and molecular devices. Herein we employed the STM break-junction
    technique to measure the single-molecule conductance of multiple π−π-stacked aromatic
    rings. We studied electron transport through up to four stacked benzene rings
    held together in an eclipsed fashion via a paracyclophane scaffold. We found that
    the strained hydrocarbons studied herein couple directly to gold electrodes during
    the measurements; hence, we did not require any heteroatom binding groups as electrical
    contacts. Density functional theory-based calculations suggest that the gold atoms
    of the electrodes bind to two neighboring carbon atoms of the outermost cyclophane
    benzene rings in η2 fashion. Our measurements show an exponential decay of the
    conductance with an increasing number of stacked benzene rings, indicating a nonresonant
    tunneling mechanism. Furthermore, STM tip−substrate displacement data provide
    additional evidence that the electrodes bind to the outermost benzene rings of
    the π−π-stacked molecular wires.

  text: Charge transport across metal–molecule interfaces has an important role in
    organic electronics1. Typically, chemical link groups such as thiols2 or amines3
    are used to bind organic molecules to metal electrodes in single-molecule circuits,
    with these groups controlling both the physical structure and the electronic coupling
    at the interface. Direct metal–carbon coupling has been shown through C60, benzene
    and π-stacked benzene4,5,6,7, but ideally the carbon backbone of the molecule
    should be covalently bonded to the electrode without intervening link groups.
    Here, we demonstrate a method to create junctions with such contacts. Trimethyl
    tin (SnMe3)-terminated polymethylene chains are used to form single-molecule junctions
    with a break-junction technique2,3. Gold atoms at the electrode displace the SnMe3
    linkers, leading to the formation of direct Au–C bonded single-molecule junctions
    with a conductance that is ∼100 times larger than analogous alkanes with most
    other terminations. The conductance of these Au–C bonded alkanes decreases exponentially
    with molecular length, with a decay constant of 0.97 per methylene, consistent
    with a non-resonant transport mechanism. Control experiments and ab initio calculations
    show that high conductances are achieved because a covalent Au–C sigma (σ) bond
    is formed. This offers a new method for making reproducible and highly conducting
    metal–organic contacts.

  text: Many membrane channels and receptors exhibit adaptive, or desensitized, response
    to a strong sustained input stimulus, often supported by protein activity-dependent
    inactivation. Adaptive response is thought to be related to various cellular functions
    such as homeostasis and enlargement of dynamic range by background compensation.
    Here we study the quantitative relation between adaptive response and background
    compensation within a modeling framework. We show that any particular type of
    adaptive response is neither sufficient nor necessary for adaptive enlargement
    of dynamic range. In particular a precise adaptive response, where system activity
    is maintained at a constant level at steady state, does not ensure a large dynamic
    range neither in input signal nor in system output. A general mechanism for input
    dynamic range enlargement can come about from the activity-dependent modulation
    of protein responsiveness by multiple biochemical modification, regardless of
    the type of adaptive response it induces. Therefore hierarchical biochemical processes
    such as methylation and phosphorylation are natural candidates to induce this
    property in signaling systems.

  text: Maximally stable component detection is a very popular method for feature
    analysis in images, mainly due to its low computation cost and high repeatability.
    With the recent advance of feature-based methods in geometric shape analysis,
    there is significant interest in finding analogous approaches in the 3D world.
    In this paper, we formulate a diffusion-geometric framework for stable component
    detection in non-rigid 3D shapes, which can be used for geometric feature detection
    and description. A quantitative evaluation of our method on the SHREC’10 feature
    detection benchmark shows its potential as a source of high-quality features.

  text: "Natural objects can be subject to various transformations yet still preserve
    properties that we refer to as invariants. Here, we use definitions of affine-invariant
    arclength for surfaces in \r\n in order to extend the set of existing non-rigid
    shape analysis tools. We show that by re-defining the surface metric as its equi-affine
    version, the surface with its modified metric tensor can be treated as a canonical
    Euclidean object on which most classical Euclidean processing and analysis tools
    can be applied. The new definition of a metric is used to extend the fast marching
    method technique for computing geodesic distances on surfaces, where now, the
    distances are defined with respect to an affine-invariant arclength. Applications
    of the proposed framework demonstrate its invariance, efficiency, and accuracy
    in shape analysis."

  text: We introduce an (equi-)affine invariant diffusion geometry by which surfaces
    that go through squeeze and shear transformations can still be properly analyzed.
    The definition of an affine invariant metric enables us to construct an invariant
    Laplacian from which local and global geometric structures are extracted. Applications
    of the proposed framework demonstrate its power in generalizing and enriching
    the existing set of tools for shape analysis.
