text: We present a method for immunolabeling of multiple species of membrane proteins
with high spatial resolution. It allows differentiation of equally sized very
small markers with different chemical compositions, which leads to high labeling
efficiency and reduces steric hindrance of closely spaced immunolabeled biomolecules.
Markers such as CdSe/ZnS semiconductor quantum dots and colloidal gold particles
are distinguished by differential contrast in high-angle annular detector dark-field
STEM mode or by EDX microanalysis of their elemental contents. This method was
tested by observation of labeled AMPA- and NMDA-type glutamate receptors on sodium-dodecyl-sulfate-digested
replica prepared from rat hippocampus. To improve particle visibility and detectability,
the replica films were made exclusively with carbon to avoid the high background
of conventional platinum/carbon replica. Extension of the method is suggested
by detection of 1.4 nm nanogold particles and its potential application in the
biological imaging research.

text: Cbln1, secreted from cerebellar granule cells, and the orphan glutamate receptor
52 (GluD2), expressed by Purkinje cells, are essential for synapse integrity between
these neurons in adult mice. Nevertheless, no endogenous binding partners for
these molecules have been identified. We found that Cblnl binds directly to the
N-terminal domain of GluD2. GluD2 expression by postsynaptic cells, combined with
exogenously applied Cbln1, was necessary and sufficient to induce new synapses
in vitro and in the adult cerebellum in vivo. Further, beads coated with recombinant
Cbln1 directly induced presynaptic differentiation and indirectly caused clustering
of postsynaptic molecules via GluD2. These results indicate that the Cbln1-GluD2
complex is a unique synapse organizer that acts bidirectionally on both pre- and
postsynaptic components.

text: Subepithelial fibroblasts of the intestinal villi, which form a contractile
cellular network beneath the epithelium, are in close contact with epithelial
cells, nerve varicosities, capillaries, smooth muscles and immune cells, and secrete
extracellular matrix molecules, growth factors and cytokines, etc. Cultured subepithelial
fibroblasts of the rat duodenal villi display various receptors such as endothelins,
ATP, substance-P and bradykinin, and release ATP in response to mechanical stimulation.
In this study, the presence of functional NK1 receptors (NK1R) was pharmacologically
confirmed in primary culture by Ca 2+ measurement, and the effects of substance-P
were measured in an acute preparation of epithelium-free duodenal villi from 2-
to 3-week-old rats using a two-photon laser microscope. Substance-P elicited an
increase in the intracellular Ca 2+ concentration and contraction of the subepithelial
fibroblasts in culture and the isolated villi. The localization of NK1R and substance-P
in the villi was examined by light and electron microscopic immunohistochemistry.
NK1R-like immunoreactivity was intensely localized on the plasma membrane of villous
subepithelial fibroblasts in 10-day- to 4-week-old rats and mice and was decreased
or absent in adulthood. The pericryptal fibroblasts of the small and large intestine
were NK1R immuno-negative. These villous subepithelial fibroblasts form synapse-like
structures with both substance-P-immunopositive and -immunonegative nerve varicosities.
Here, we propose that the mutual interaction between villous subepithelial fibroblasts
and afferent neurons via substance-P and ATP plays important roles in the maturation
of the structure and function of the small intestine.

text: T-type calcium channels play a pivotal role in regulating neural membrane
excitability in the nervous system. However, the precise subcellular distributions
of T-type channel subunits and their implication for membrane excitability are
not well understood. Here we investigated the subcellular distribution of the
α1G subunit of the calcium channel which is expressed highly in the mouse dorsal
lateral geniculate nucleus (dLGN). Light microscopic analysis demonstrated that
dLGN exhibits intense immunoperoxidase reactivity for the α1G subunit. Electron
microscopic observation showed that the labeling was present in both the relay
cells and interneurons and was found in the somatodendritic, but not axonal, domains
of these cells. Most of the immunogold particles for the α1G subunit were either
associated with the plasma membrane or the intracellular membranes. Reconstruction
analysis of serial electron microscopic images revealed that the intensity of
the intracellular labeling exhibited a gradient such that the labeling density
was higher in the proximal dendrite and progressively decreased towards the distal
dendrite. In contrast, the plasma membrane-associated particles were distributed
with a uniform density over the somatodendritic surface of dLGN cells. The labeling
density in the relay cell plasma membrane was about 3-fold higher than that of
the interneurons. These results provide ultrastructural evidence for cell-type-specific
expression levels and for uniform expression density of the α1G subunit over the
plasma membrane of dLGN cells.

text: 'The activity patterns of subthalamic nucleus (STN) neurons are intimately
linked to motor function and dysfunction and arise through the complex interaction
of intrinsic properties and inhibitory and excitatory synaptic inputs. In many
neurons, hyperpolarization-activated cyclic nucleotide-gated (HCN) channels play
key roles in intrinsic excitability and synaptic integration both under normal
conditions and in disease states. However, in STN neurons, which strongly express
HCN channels, their roles remain relatively obscure. To address this deficit,
complementary molecular and cellular electrophysiological, imaging, and computational
approaches were applied to the rat STN. Molecular profiling demonstrated that
individual STN neurons express mRNA encoding several HCN subunits, with HCN2 and
3 being the most abundant. Light and electron microscopic analysis showed that
HCN2 subunits are strongly expressed and distributed throughout the somatodendritic
plasma membrane. Voltage-, current-, and dynamic-clamp analysis, two-photon Ca
2+ imaging, and computational modeling revealed that HCN channels are activated
by GABA A receptor-mediated inputs and thus limit synaptic hyperpolarization and
deinactivation of low-voltage-activated Ca 2+ channels. Although HCN channels
also limited the temporal summation of EPSPs, generated through two-photon uncaging
of glutamate, this action was largely shunted by GABAergic inhibition that was
necessary for HCN channel activation. Together the data demonstrate that HCN channels
in STN neurons selectively counteract GABA A receptor-mediated inhibition arising
from the globus pallidus and thus promote single-spike activity rather than rebound
burst firing. '

text: Hippocampal CA1 pyramidal cells, which receive γ-aminobutyric acid (GABA)ergic
input from at least 18 types of presynaptic neuron, express 14 subunits of the
pentameric GABAA receptor. The relative contribution of any subunit to synaptic
and extrasynaptic receptors influences the dynamics of GABA and drug actions.
Synaptic receptors mediate phasic GABA-evoked conductance and extrasynaptic receptors
contribute to a tonic conductance. We used freeze-fracture replica-immunogold
labelling, a sensitive quantitative immunocytochemical method, to detect synaptic
and extrasynaptic pools of the alpha1, alpha2 and beta3 subunits. Antibodies to
the cytoplasmic loop of the subunits showed immunogold particles concentrated
on distinct clusters of intramembrane particles (IMPs) on the cytoplasmic face
of the plasma membrane on the somata, dendrites and axon initial segments, with
an abrupt decrease in labelling at the edge of the IMP cluster. Neuroligin-2,
a GABAergic synapse-specific adhesion molecule, co-labels all beta3 subunit-rich
IMP clusters, therefore we considered them synapses. Double-labelling for two
subunits showed that virtually all somatic synapses contain the alpha1, alpha2
and beta3 subunits. The extrasynaptic plasma membrane of the somata, dendrites
and dendritic spines showed low-density immunolabelling. Synaptic labelling densities
on somata for the alpha1, alpha2 and beta3 subunits were 78-132, 94 and 79 times
higher than on the extrasynaptic membranes, respectively. As GABAergic synapses
occupy 0.72% of the soma surface, the fraction of synaptic labelling was 33-48
(alpha1), 40 (alpha2) and 36 (beta3)% of the total somatic surface immunolabelling.
Assuming similar antibody access to all receptors, about 60% of these subunits
are in extrasynaptic receptors.

text: Neurons in the laterocapsular division of the central nucleus of the amygdala
(CeC), which is known as the "nociceptive amygdala," receive glutamatergic
inputs from the parabrachial nucleus (PB) and the basolateral nucleus of amygdala
(BLA), which convey nociceptive information from the dorsal horn of the spinal
cord and polymodal information from the thalamus and cortex, respectively. Here,
we examined the ultrastructural properties of PB- and BLA-CeC synapses identified
with EGFP-expressing lentivirus in rats. In addition, the density of synaptic
AMPA receptors (AMPARs) on CeC neurons was studied by using highly sensitive SDS-digested
freeze-fracture replica labeling (SDS-FRL). Afferents from the PB made asymmetrical
synapses mainly on dendritic shafts (88%), whereas those from the BLA were on
dendritic spines (81%). PB-CeC synapses in dendritic shafts were significantly
larger (median 0.072 μm 2) than BLA-CeC synapses in spines (median 0.058 μm 2;
P = 0.02). The dendritic shafts that made synapses with PB fibers were also significantly
larger than those that made synapses with BLA fibers, indicating that the PB fibers
make synapses on more proximal parts of dendrites than the BLA fibers. SDS-FRL
revealed that almost all excitatory postsynaptic sites have AMPARs in the CeC.
The density of AMPAR-specific gold particles in individual synapses was significantly
higher in spine synapses (median 510 particles/μm 2) than in shaft synapses (median
427 particles/μm 2; P = 0.01). These results suggest that distinct synaptic impacts
from PB- and BLA-CeC pathways contribute to the integration of nociceptive and
polymodal information in the CeC.

text: Morphogens are secreted signalling molecules that act in a graded manner to
control the pattern of cellular differentiation in developing tissues. An example
is Sonic hedgehog (Shh), which acts in several developing vertebrate tissues,
including the central nervous system, to provide positional information during
embryonic patterning. Here we address how Shh signalling assigns the positional
identities of distinct neuronal subtype progenitors throughout the ventral neural
tube. Assays of intracellular signal transduction and gene expression indicate
that the duration as well as level of signalling is critical for morphogen interpretation.
Progenitors of the ventral neuronal subtypes are established sequentially, with
progressively more ventral identities requiring correspondingly higher levels
and longer periods of Shh signalling. Moreover, cells remain sensitive to changes
in Shh signalling for an extended time, reverting to antecedent identities if
signalling levels fall below a threshold. Thus, the duration of signalling is
important not only for the assignment but also for the refinement and maintenance
of positional identity. Together the data suggest a dynamic model for ventral
neural tube patterning in which positional information corresponds to the time
integral of Shh signalling. This suggests an alternative to conventional models
of morphogen action that rely solely on the level of signalling.

text: The epitaxial growth of germanium on silicon leads to the self-assembly of
SiGe nanocrystals by a process that allows the size, composition and position
of the nanocrystals to be controlled. This level of control, combined with an
inherent compatibility with silicon technology, could prove useful in nanoelectronic
applications. Here, we report the confinement of holes in quantum-dot devices
made by directly contacting individual SiGe nanocrystals with aluminium electrodes,
and the production of hybrid superconductor- semiconductor devices, such as resonant
supercurrent transistors, when the quantum dot is strongly coupled to the electrodes.
Charge transport measurements on weakly coupled quantum dots reveal discrete energy
spectra, with the confined hole states displaying anisotropic gyromagnetic factors
and strong spin-orbit coupling with pronounced dependences on gate voltage and
magnetic field.

text: We investigate electronic transport in n-i-n GaN nanowires with and without
AlN double barriers. The nanowires are grown by catalyst-free, plasma-assisted
molecular beam epitaxy enabling abrupt GaN/AlN interfaces as well as longitudinal
n-type doping modulation. At low temperature, transport in n-i-n GaN nanowires
is dominated by the Coulomb blockade effect. Carriers are confined in the undoped
middle region, forming single or multiple islands with a characteristic length
of ∼100 nm. The incorporation of two AlN tunnel barriers causes confinement to
occur within the GaN dot in between. In the case of a 6 nm thick dot and 2 nm
thick barriers, we observe characteristic signatures of Coulomb-blockaded transport
in single quantum dots with discrete energy states. For thinner dots and barriers,
Coulomb-blockade effects do not play a significant role while the onset of resonant
tunneling via the confined quantum levels is accompanied by a negative differential
resistance surviving up to ∼150 K.

text: It has been proposed that primordial gas in early dark matter halos, with
virial temperatures above 10^4 K, can avoid fragmentation and undergo rapid collapse,
possibly resulting in a supermassive black hole (SMBH). This requires the gas
to avoid cooling and to remain at temperatures near T=10^4 K. We show that this
condition can be satisfied in the presence of a sufficiently strong primordial
magnetic field, which heats the collapsing gas via ambipolar diffusion. If the
field has a strength above B = 3.6 (comoving) nG, the collapsing gas is kept warm
(T=10^4K) until it reaches the critical density n_crit=10^3 cm^{-3} at which the
roto-vibrational states of H_2 approach local thermodynamic equilibrium. H_2-cooling
then remains inefficient, and the gas temperature stays near 10^4K, even as it
continues to collapse to higher densities. The critical magnetic field strength
required to permanently suppress H_2-cooling is somewhat higher than upper limit
of approx. 2 nG from the cosmic microwave background (CMB). However, it can be
realized in the rare (2-3)-sigma regions of the spatially fluctuating B-field;
these regions contain a sufficient number of halos to account for the z=6 quasar
BHs.

text: In the absence of H_2 molecules, the primordial gas in early dark matter halos
with virial temperatures just above T_vir >~ 10^4 K cools by collisional excitation
of atomic H. Although it cools efficiently, this gas remains relatively hot, at
a temperature near T ~ 8000 K, and consequently might be able to avoid fragmentation
and collapse directly into a supermassive black hole (SMBH). In order for H_2--formation
and cooling to be strongly suppressed, the gas must be irradiated by a sufficiently
intense ultraviolet (UV) flux. We performed a suite of three--dimensional hydrodynamical
adaptive mesh refinement (AMR) simulations of gas collapse in three different
protogalactic halos with T_vir >~ 10^4 K, irradiated by a UV flux with various
intensities and spectra. We determined the critical specific intensity, Jcrit,
required to suppress H_2 cooling in each of the three halos. For a hard spectrum
representative of metal--free stars, we find (in units of 10^{-21} erg s^{-1}

text: Supermassive black holes (SMBHs) are common in local galactic nuclei, and
SMBHs as massive as several billion solar masses already exist at redshift z=6.
These earliest SMBHs may arise by the combination of Eddington-limited growth
and mergers of stellar-mass seed BHs left behind by the first generation of metal-free
stars, or by the rapid direct collapse of gas in rare special environments where
the gas can avoid fragmenting into stars. In this contribution, I review these
two competing scenarios. I also briefly mention some more exotic ideas and how
the different models may be distinguished in the future by LISA and other instruments.

text: Finding electromagnetic (EM) counterparts of future gravitational wave (GW)
sources would bring rich scientific benefits. A promising possibility, in the
case of the coalescence of a supermassive black hole binary (SMBHB), is that the
prompt emission from merger-induced disturbances in a supersonic circumbinary
disc may be detectable. We follow the post-merger evolution of a thin, zero-viscosity
circumbinary gas disc with two-dimensional simulations, using the hydrodynamic
code flash. We analyse perturbations arising from the 530 km s−1 recoil of a 106
M⊙ binary, oriented in the plane of the disc, assuming either a non-radiative
gamma-law or a pseudo-isothermal equation of state for the gas. We find that a
single-armed spiral shock wave forms and propagates outwards, sweeping up ∼40
per cent of the mass of the disc. The morphology and evolution of the perturbations
agrees well with those of caustics predicted to occur in a collisionless disc.
Assuming that the disc radiates nearly instantaneously to maintain a constant
temperature, we estimate the amount of dissipation and corresponding post-merger
light curve. The luminosity rises steadily on the time-scale of months, and reaches
few ×1043 erg s−1, corresponding to ≈10 per cent of the Eddington luminosity of
the central SMBHB. We also analyse the case in which gravitational wave emission
results in a 5 per cent mass loss in the merger remnant. The mass loss reduces
the shock overdensities and the overall luminosity of the disc by ≈15–20 per cent,
without any other major effects on the spiral shock pattern.

text: The coalescence of a supermassive black hole binary (SMBHB) is thought to
be accompanied by an electromagnetic (EM) afterglow, produced by the viscous infall
of the surrounding circumbinary gas disk after the merger. It has been proposed
that once the merger has been detected in gravitational waves (GWs) by LISA, follow-up
EM searches for this afterglow can help identify the EM counterpart of the LISA
source. Here we study whether the afterglows may be sufficiently bright and numerous
to be detectable in EM surveys alone. The viscous afterglow, which lasts for years
to decades for SMBHBs in LISA's sensitivity window, is characterized by rapid
increases in both the bolometric luminosity and in the spectral hardness of the
source. If quasar activity is triggered by the same major galaxy mergers that
produce SMBHBs, then the afterglow could be interpreted as a signature of the
birth of a quasar. Using an idealized model for the post-merger viscous spreading
of the circumbinary disk and the resulting light curve, and using the observed
luminosity function of quasars as a proxy for the SMBHB merger rate, we delineate
the survey requirements for identifying such birthing quasars. If circumbinary
disks have a high disk surface density and viscosity, an all-sky soft X-ray survey
with a sensitivity of ~<3x10^-14 erg s^-1 cm^-2 and a time resolution of ~months
could identify dozens of birthing quasars with sustained brightening rates of
>10%/yr. If >1% of the X-ray emission is reprocessed into optical frequencies,
birthing quasars could also be identified in optical transient surveys such as
the LSST. Distinguishing a birthing quasar from other variable sources may be
facilitated by the monotonic hardening of its spectrum, but will likely remain
challenging. This reinforces the notion that joint EM-plus-GW observations offer
the best prospects for identifying the EM signatures of SMBHB mergers.

text: Clusters of galaxies have been extensively used to determine cosmological
parameters. A major difficulty in making the best use of Sunyaev–Zel'dovich (SZ)
and X-ray observations of clusters for cosmology is that using X-ray observations
it is difficult to measure the temperature distribution and therefore determine
the density distribution in individual clusters of galaxies out to the virial
radius. Observations with the new generation of SZ instruments are a promising
alternative approach. We use clusters of galaxies drawn from high-resolution adaptive
mesh refinement cosmological simulations to study how well we should be able to
constrain the large-scale distribution of the intracluster gas (ICG) in individual
massive relaxed clusters using AMiBA in its configuration with 13 1.2 m diameter
dishes (AMiBA13) along with X-ray observations. We show that non-isothermal β
models provide a good description of the ICG in our simulated relaxed clusters.
We use simulated X-ray observations to estimate the quality of constraints on
the distribution of gas density, and simulated SZ visibilities (AMiBA13 observations)
for constraints on the large-scale temperature distribution of the ICG. We find
that AMiBA13 visibilities should constrain the scale radius of the temperature
distribution to about 50% accuracy. We conclude that the upgraded AMiBA, AMiBA13,
should be a powerful instrument to constrain the large-scale distribution of the
ICG.

text: We propose counting peaks in weak lensing (WL) maps, as a function of their
height, to probe models of dark energy and to constrain cosmological parameters.
Because peaks can be identified in two-dimensional WL maps directly, they can
provide constraints that are free from potential selection effects and biases
involved in identifying and determining the masses of galaxy clusters. We have
run cosmological N-body simulations to produce WL convergence maps in three models
with different constant values of the dark energy equation of state parameter,
w=-0.8, -1, and -1.2, with a fixed normalization of the primordial power spectrum
(corresponding to present-day normalizations of sigma8=0.742, 0.798, and 0.839,
respectively). By comparing the number of WL peaks in 8 convergence bins in the
range of -0.1 < kappa < 0.2, in multiple realizations of a single simulated 3x3
degree field, we show that the first (last) pair of models can be distinguished
at the 95% (85%) confidence level. A survey with depth and area (20,000 sq. degrees),
comparable to those expected from LSST, should have a factor of approx. 50 better
parameter sensitivity. We find that relatively low-amplitude peaks (kappa = 0.03),
which typically do not correspond to a single collapsed halo along the line of
sight, account for most of this sensitivity. We study a range of smoothing scales
and source galaxy redshifts (z_s). With a fixed source galaxy density of 15/arcmin^2,
the best results are provided by the smallest scale we can reliably simulate,
1 arcminute, and z_s=2 provides substantially better sensitivity than z_s< 1.5.

text: We present the realization of a cavity quantum electrodynamics setup in which
photons of strongly different lifetimes are engineered in different harmonic modes
of the same cavity. We achieve this in a superconducting transmission line resonator
with superconducting qubits coupled to the different modes. One cavity mode is
strongly coupled to a detection line for qubit state readout, while a second long
lifetime mode is used for photon storage and coherent quantum operations. We demonstrate
sideband-based measurement of photon coherence, generation of n photon Fock states
and the scaling of the sideband Rabi frequency with √n using a scheme that may
be extended to realize sideband-based two-qubit logic gates.

text: The quantum properties of electromagnetic, mechanical or other harmonic oscillators
can be revealed by investigating their strong coherent coupling to a single quantum
two level system in an approach known as cavity quantum electrodynamics (QED).
At temperatures much lower than the characteristic energy level spacing the observation
of vacuum Rabi oscillations or mode splittings with one or a few quanta asserts
the quantum nature of the oscillator. Here, we study how the classical response
of a cavity QED system emerges from the quantum one when its thermal occupation-or
effective temperature-is raised gradually over 5 orders of magnitude. In this
way we explore in detail the continuous quantum-to-classical crossover and demonstrate
how to extract effective cavity field temperatures from both spectroscopic and
time-resolved vacuum Rabi measurements.
