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.

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: Cortical neurons receive balanced excitatory and inhibitory synaptic currents.
Such a balance could be established and maintained in an experience-dependent
manner by synaptic plasticity at inhibitory synapses. We show that this mechanism
provides an explanation for the sparse firing patterns observed in response to
natural stimuli and fits well with a recently observed interaction of excitatory
and inhibitory receptive field plasticity. The introduction of inhibitory plasticity
in suitable recurrent networks provides a homeostatic mechanism that leads to
asynchronous irregular network states. Further, it can accommodate synaptic memories
with activity patterns that become indiscernible from the background state but
can be reactivated by external stimuli. Our results suggest an essential role
of inhibitory plasticity in the formation and maintenance of functional cortical
circuitry.

text: The accurate experimental determination of dipolar-coupling constants for
one-bond heteronuclear dipolar couplings in solids is a key for the quantification
of the amplitudes of motional processes. Averaging of the dipolar coupling reports
on motions on time scales up to the inverse of the coupling constant, in our case
tens of microseconds. Combining dipolar-coupling derived order parameters that
characterize the amplitudes of the motion with relaxation data leads to a more
precise characterization of the dynamical parameters and helps to disentangle
the amplitudes and the time scales of the motional processes, which impact relaxation
rates in a highly correlated way. Here. we describe and characterize an improved
experimental protocol – based on REDOR – to measure these couplings in perdeuterated
proteins with a reduced sensitivity to experimental missettings. Because such
effects are presently the dominant source of systematic errors in experimental
dipolar-coupling measurements, these compensated experiments should help to significantly
improve the precision of such data. A detailed comparison with other commonly
used pulse sequences (T-MREV, phase-inverted CP,R18 5/2, and R18 7/1) is provided.

text: Despite the importance of protein fibrils in the context of conformational
diseases, information on their structure is still sparse. Hydrogen/deuterium exchange
measurements of backbone amide protons allow the identification hydrogen-bonding
patterns and reveal pertinent information on the amyloid β-sheet architecture.
However, they provide only little information on the identity of residues exposed
to solvent or buried inside the fibril core. NMR spectroscopy is a potent method
for identifying solvent-accessible residues in proteins via observation of polarization
transfer between chemically exchanging side-chain protons and water protons. We
show here that the combined use of highly deuterated samples and fast magic-angle
spinning greatly attenuates unwanted spin diffusion and allows identification
of polarization exchange with the solvent in a site-specific manner. We apply
this measurement protocol to HET-s(218–289) prion fibrils under different conditions
(including physiological pH, where protofibrils assemble together into thicker
fibrils) and demonstrate that each protofibril of HET-s(218–289), is surrounded
by water, thus excluding the existence of extended dry interfibril contacts. We
also show that exchangeable side-chain protons inside the hydrophobic core of
HET-s(218–289) do not exchange over time intervals of weeks to months. The experiments
proposed in this study can provide insight into the detailed structural features
of amyloid fibrils in general.

text: The classical principle of least action says that orbits of mechanical systems
extremize action; an important subclass are those orbits that minimize action.
In this paper we utilize this principle along with Aubry-Mather theory to construct
(Birkhoff) regions of instability for a certain three-body problem, given by a
Hamiltonian system of 2 degrees of freedom. We believe that these methods can
be applied to construct instability regions for a variety of Hamiltonian systems
with 2 degrees of freedom. The Hamiltonian model we consider describes dynamics
of a Sun-Jupiter-comet system, and under some simplifying assumptions, we show
the existence of instabilities for the orbit of the comet. In particular, we show
that a comet which starts close to an orbit in the shape of an ellipse of eccentricity
e=0.66 can increase in eccentricity up to e=0.96. In the sequels to this paper,
we extend the result to beyond e=1 and show the existence of ejection orbits.
Such orbits are initially well within the range of our solar system. This might
give an indication of why most objects rotating around the Sun in our solar system
have relatively low eccentricity.
