text: Chandelier (axoaxonic) cells (ChCs) are a distinct group of GABAergic interneurons
that innervate the axon initial segments of pyramidal cells. However, their circuit
role and the function of their clearly defined anatomical specificity remain unclear.
Recent work has demonstrated that chandelier cells can produce depolarizing GABAergic
PSPs, occasionally driving postsynaptic targets to spike. On the other hand, other
work suggests that ChCs are hyperpolarizing and may have an inhibitory role. These
disparate functional effects may reflect heterogeneity among ChCs. Here, using
brain slices from transgenic mouse strains, we first demonstrate that, across
different neocortical areas and genetic backgrounds, upper Layer 2/3 ChCs belong
to a single electrophysiologically and morphologically defined population, extensively
sampling Layer 1 inputs with asymmetric dendrites. Consistent with being a single
cell type, we find electrical coupling between ChCs. We then investigate the effect
of chandelier cell activation on pyramidal neuron spiking in several conditions,
ranging from the resting membrane potential to stimuli designed to approximate
in vivo membrane potential dynamics. We find that under quiescent conditions,
chandelier cells are capable of both promoting and inhibiting spike generation,
depending on the postsynaptic membrane potential. However, during in vivo-like
membrane potential fluctuations, the dominant postsynaptic effect was a strong
inhibition. Thus, neocortical chandelier cells, even from within a homogeneous
population, appear to play a dual role in the circuit, helping to activate quiescent
pyramidal neurons, while at the same time inhibiting active ones.

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: A wide range of experiments studying microwave photons localized in superconducting
cavities have made important contributions to our understanding of the quantum
properties of radiation. Propagating microwave photons, however, have so far been
studied much less intensely. Here we present measurements in which we reconstruct
the quantum state of itinerant single photon Fock states and their superposition
with the vacuum by analyzing moments of the measured amplitude distribution up
to fourth order. Using linear amplifiers and quadrature amplitude detectors, we
have developed efficient methods to separate the detected single photon signal
from the noise added by the amplifier. From our measurement data we have also
reconstructed the corresponding Wigner function.

text: Creating a train of single photons and monitoring its propagation and interaction
is challenging in most physical systems, as photons generally interact very weakly
with other systems. However, when confining microwave frequency photons in a transmission
line resonator, effective photon-photon interactions can be mediated by qubits
embedded in the resonator. Here, we observe the phenomenon of photon blockade
through second-order correlation function measurements. The experiments clearly
demonstrate antibunching in a continuously pumped source of single microwave photons
measured by using microwave beam splitters, linear amplifiers, and quadrature
amplitude detectors. We also investigate resonance fluorescence and Rayleigh scattering
in Mollow-triplet-like spectra.

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: 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: We consider Markov Decision Processes (MDPs) with mean-payoff parity and energy
parity objectives. In system design, the parity objective is used to encode ω-regular
specifications, and the mean-payoff and energy objectives can be used to model
quantitative resource constraints. The energy condition re- quires that the resource
level never drops below 0, and the mean-payoff condi- tion requires that the limit-average
value of the resource consumption is within a threshold. While these two (energy
and mean-payoff) classical conditions are equivalent for two-player games, we
show that they differ for MDPs. We show that the problem of deciding whether a
state is almost-sure winning (i.e., winning with probability 1) in energy parity
MDPs is in NP ∩ coNP, while for mean- payoff parity MDPs, the problem is solvable
in polynomial time, improving a recent PSPACE bound.

text: Variation in food quality and abundance requires animals to decide whether
to stay on a poor food patch or leave in search of better food. An important question
in behavioral ecology asks when is it optimal for an animal to leave a food patch
it is depleting. Although optimal foraging is central to evolutionary success,
the neural and molecular mechanisms underlying it are poorly understood. Here
we investigate the neuronal basis for adaptive food-leaving behavior in response
to resource depletion in Caenorhabditis elegans, and identify several of the signaling
pathways involved. The ASE neurons, previously implicated in salt chemoattraction,
promote food-leaving behavior via a cGMP pathway as food becomes limited. High
ambient O2 promotes food-leaving via the O2-sensing neurons AQR, PQR, and URX.
Ectopic activation of these neurons using channelrhodopsin is sufficient to induce
high food-leaving behavior. In contrast, the neuropeptide receptor NPR-1, which
regulates social behavior on food, acts in the ASE neurons, the nociceptive ASH
neurons, and in the RMG interneuron to repress food-leaving. Finally, we show
that neuroendocrine signaling by TGF-β/DAF-7 and neuronal insulin signaling are
necessary for adaptive food-leaving behavior. We suggest that animals integrate
information about their nutritional state with ambient oxygen and gustatory stimuli
to formulate optimal foraging strategies.

text: 'Genome sequence comparisons have highlighted many novel gene families that
are conserved across animal phyla but whose biological function is unknown. Here,
we functionally characterize a member of one such family, the macoilins. Macoilins
are characterized by several highly conserved predicted transmembrane domains
towards the N-terminus and by coiled-coil regions C-terminally. They are found
throughout Eumetazoa but not in other organisms. Mutants for the single Caenorhabditis
elegans macoilin, maco-1, exhibit a constellation of behavioral phenotypes, including
defects in aggregation, O2 responses, and swimming. MACO-1 protein is expressed
broadly and specifically in the nervous system and localizes to the rough endoplasmic
reticulum; it is excluded from dendrites and axons. Apart from subtle synapse
defects, nervous system development appears wild-type in maco-1 mutants. However,
maco-1 animals are resistant to the cholinesterase inhibitor aldicarb and sensitive
to levamisole, suggesting pre-synaptic defects. Using in vivo imaging, we show
that macoilin is required to evoke Ca2+ transients, at least in some neurons:
in maco-1 mutants the O2-sensing neuron PQR is unable to generate a Ca2+ response
to a rise in O2. By genetically disrupting neurotransmission, we show that pre-synaptic
input is not necessary for PQR to respond to O2, indicating that the response
is mediated by cell-intrinsic sensory transduction and amplification. Disrupting
the sodium leak channels NCA-1/NCA-2, or the N-,P/Q,R-type voltage-gated Ca2+
channels, also fails to disrupt Ca2+ responses in the PQR cell body to O2 stimuli.
By contrast, mutations in egl-19, which encodes the only Caenorhabditis elegans
L-type voltage-gated Ca2+ channel α1 subunit, recapitulate the Ca2+ response defect
we see in maco-1 mutants, although we do not see defects in localization of EGL-19.

text: Tumor necrosis factor-stimulated gene-6 (TSG-6) is a hyalu-ronan (HA)-binding
protein that plays important roles ininflammation and ovulation. TSG-6-mediated
cross-linking ofHA has been proposed as a functional mechanism (e.g.for regu-lating
leukocyte adhesion), but direct evidence for cross-linkingis lacking, and we know
very little about its impact on HA ultra-structure. Here we used films of polymeric
and oligomeric HAchains, end-grafted to a solid support, and a combination ofsurface-sensitive
biophysical techniques to quantify the bindingof TSG-6 into HA films and to correlate
binding to morpholog-ical changes. We find that full-length TSG-6 binds with pro-nounced
positive cooperativity and demonstrate that it cancross-link HA at physiologically
relevant concentrations. Ourdata indicate that cooperative binding of full-length
TSG-6arises from HA-induced protein oligomerization and that theTSG-6 oligomers
act as cross-linkers. In contrast, the HA-bind-ing domain of TSG-6 (the Link module)
alone binds withoutpositive cooperativity and weaker than the full-length protein.Both
the Link module and full-length TSG-6 condensed andrigidified HA films, and the
degree of condensation scaled withthe affinity between the TSG-6 constructs and
HA. We proposethat condensation is the result of protein-mediated HA cross-linking.
Our findings firmly establish that TSG-6 is a potent HAcross-linking agent and
might hence have important implica-tions for the mechanistic understanding of
the biological func-tion of TSG-6 (e.g.in inflammation).

text: We report the switching behavior of the full bacterial flagellum system that
includes the filament and the motor in wild-type Escherichia coli cells. In sorting
the motor behavior by the clockwise bias, we find that the distributions of the
clockwise (CW) and counterclockwise (CCW) intervals are either exponential or
nonexponential with long tails. At low bias, CW intervals are exponentially distributed
and CCW intervals exhibit long tails. At intermediate CW bias (0.5) both CW and
CCW intervals are mainly exponentially distributed. A simple model suggests that
these two distinct switching behaviors are governed by the presence of signaling
noise within the chemotaxis network. Low noise yields exponentially distributed
intervals, whereas large noise yields nonexponential behavior with long tails.
These drastically different motor statistics may play a role in optimizing bacterial
behavior for a wide range of environmental conditions.

text: This article refers to algorithms based on finite difference schemes for computing
mean and affine curvature evolutions of digital images, introduced by Alvarez
and Morel [L. Alvarez, J.M. Morel, “Formalization and computational aspects of
image analysis”, Acta Numerica, pp. 159, 1994]. We discuss consistency, stability
and convergence. Our analysis focuses on some possible choices of the parameters,
choices that generate multiple variants in the implementations. Meaningful visual
examples on how the algorithms actually work are provided.

text: We perform numerical simulations to study self-assembly of nanoparticles mediated
by an elastic planar surface. We show how the nontrivial elastic response to deformations
of these surfaces leads to anisotropic interactions between the particles resulting
in aggregates having different geometrical features. The morphology of the patterns
can be controlled by the mechanical properties of the surface and the strength
of the particle adhesion. We use simple scaling arguments to understand the formation
of the different structures, and we show how the adhering particles can cause
the underlying elastic substrate to wrinkle if two of its opposite edges are clamped.
Finally, we discuss the implications of our results and suggest how elastic surfaces
could be used in nanofabrication.

text: We produce an ultracold and dense sample of rovibronic ground state Cs 2 molecules
close to the regime of quantum degeneracy, in a single hyperfine level, in the
presence of an optical lattice. The molecules are individually trapped, in the
motional ground state of an optical lattice well, with a lifetime of 8 s. For
preparation, we start with a zero-temperature atomic Mott-insulator state with
optimized double-site occupancy and efficiently associate weakly-bound dimer molecules
on a Feshbach resonance. Despite extremely weak Franck-Condon wavefunction overlap,
the molecules are subsequently transferred with >50% efficiency to the rovibronic
ground state by a stimulated four-photon process. Our results present a crucial
step towards the generation of Bose-Einstein condensates of ground-state molecules
and, when suitably generalized to polar heteronuclear molecules such as RbCs,
the realization of dipolar many-body quantum-gas phases in periodic potentials.

text: We present experimentally derived potential curves 1?and spin-orbit interaction
functions for the strongly perturbed AΣu+ 3?and bΠu states of the cesium dimer.
The results are based on data from several sources. Laser-induced fluorescence
Fourier transform spectroscopy (LIF FTS) was used some time ago in the Laboratoire
Aimé Cotton primarily to study the XΣg+ state. More recent work at Tsinghua University
provides information from moderate 3?resolution spectroscopy on the lowest levels
of the bΠ0u± state as well as additional high-resolution data. From Innsbruck
University, we have precision data obtained with cold Cs2 molecules. Recent data
from Temple University was obtained using the optical-optical double resonance
polarization spectroscopy technique, and finally, a group at the University of
Latvia has added additional LIF FTS data. In the Hamiltonian matrix, we have used
analytic potentials (the expanded Morse oscillator form) with both finite-difference
(FD) coupled-channel and discrete variable representation (DVR) calculations of
the term values. Fitted diagonal and off-diagonal spin-orbit functions are obtained
and compared with ab initio results from Temple and Moscow State universities.

text: The present paper aims at finding optimal parameters for trapping of Cs 2
molecules in optical lattices, with the perspective of creating a quantum degenerate
gas of ground-state molecules. We have calculated dynamic polarizabilities of
Cs 2 molecules subject to an oscillating electric field, using accurate potential
curves and electronic transition dipole moments. We show that for some particular
wavelengths of the optical lattice, called "magic wavelengths", the
polarizability of the ground-state molecules is equal to the one of a Feshbach
molecule. As the creation of the sample of ground-state molecules relies on an
adiabatic population transfer from weakly-bound molecules created on a Feshbach
resonance, such a coincidence ensures that both the initial and final states are
favorably trapped by the lattice light, allowing optimized transfer in agreement
with the experimental observation.

text: We perform precision measurements on a Mott-insulator quantum state of ultracold
atoms with tunable interactions. We probe the dependence of the superfluid-to-Mott-insulator
transition on the interaction strength and explore the limits of the standard
Bose-Hubbard model description. By tuning the on-site interaction energies to
values comparable to the interband separation, we are able to quantitatively measure
number-dependent shifts in the excitation spectrum caused by effective multibody
interactions.
