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: 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.

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: Continuous variable entanglement between two modes of a radiation field is
usually studied at optical frequencies. Here we demonstrate experiments that show
the entanglement between microwave photons of different energy in a broadband
squeezed beam. We use a Josephson parametric amplifier to generate the two-mode
correlated state and detect all four quadrature components simultaneously in a
two-channel heterodyne setup using amplitude detectors. Analyzing two-dimensional
phase space histograms for all possible pairs of quadratures allows us to determine
the full covariance matrix, which is in good agreement with the one expected for
a two-mode squeezed state.

text: During assembly of the Drosophila olfactory circuit, projection neuron (PN)
dendrites prepattern the developing antennal lobe before the arrival of axons
from their presynaptic partners, the adult olfactory receptor neurons (ORNs).
We previously found that levels of transmembrane Semaphorin-1a, which acts as
a receptor, instruct PN dendrite targeting along the dorsolateral-ventromedial
axis. Here we show that two secreted semaphorins, Sema-2a and Sema-2b, provide
spatial cues for PN dendrite targeting. Sema-2a and Sema-2b proteins are distributed
in gradients opposing the Sema-1a protein gradient, and Sema-1a binds to Sema-2a-expressing
cells. In Sema-2a and Sema-2b double mutants, PN dendrites that normally target
dorsolaterally in the antennal lobe mistarget ventromedially, phenocopying cell-autonomous
Sema-1a removal from these PNs. Cell ablation, cell-specific knockdown, and rescue
experiments indicate that secreted semaphorins from degenerating larval ORN axons
direct dendrite targeting. Thus, a degenerating brain structure instructs the
wiring of a developing circuit through the repulsive action of secreted semaphorins.

text: Longitudinal axon fascicles within the Drosophila embryonic CNS provide connections
between body segments and are required for coordinated neural signaling along
the anterior-posterior axis. We show here that establishment of select CNS longitudinal
tracts and formation of precise mechanosensory afferent innervation to the same
CNS region are coordinately regulated by the secreted semaphorins Sema-2a and
Sema-2b. Both Sema-2a and Sema-2b utilize the same neuronal receptor, plexin B
(PlexB), but serve distinct guidance functions. Localized Sema-2b attraction promotes
the initial assembly of a subset of CNS longitudinal projections and subsequent
targeting of chordotonal sensory afferent axons to these same longitudinal connectives,
whereas broader Sema-2a repulsion serves to prevent aberrant innervation. In the
absence of Sema-2b or PlexB, chordotonal afferent connectivity within the CNS
is severely disrupted, resulting in specific larval behavioral deficits. These
results reveal that distinct semaphorin-mediated guidance functions converge at
PlexB and are critical for functional neural circuit assembly.
