text: A lower bound is derived on the free energy (per unit volume) of a homogeneous
Bose gas at density Q and temperature T. In the dilute regime, i.e., when a3 1,
where a denotes the scattering length of the pair-interaction potential, our bound
differs to leading order from the expression for non-interacting particles by
the term 4πa(2 2}-[ - c]2+). Here, c(T) denotes the critical density for Bose-Einstein
condensation (for the non-interacting gas), and [ · ]+ = max{ ·, 0} denotes the
positive part. Our bound is uniform in the temperature up to temperatures of the
order of the critical temperature, i.e., T ~ 2/3 or smaller. One of the key ingredients
in the proof is the use of coherent states to extend the method introduced in
[17] for estimating correlations to temperatures below the critical one.

text: We derive upper and lower bounds on the critical temperature Tc and the energy
gap Ξ (at zero temperature) for the BCS gap equation, describing spin- 1 2 fermions
interacting via a local two-body interaction potential λV(x). At weak coupling
λ 1 and under appropriate assumptions on V(x), our bounds show that Tc ∼A exp(-B/λ)
and Ξ∼C exp(-B/λ) for some explicit coefficients A, B, and C depending on the
interaction V(x) and the chemical potential μ. The ratio A/C turns out to be a
universal constant, independent of both V(x) and μ. Our analysis is valid for
any μ; for small μ, or low density, our formulas reduce to well-known expressions
involving the scattering length of V(x).

text: We derive a lower bound on the ground state energy of the Hubbard model for
given value of the total spin. In combination with the upper bound derived previously
by Giuliani (J. Math. Phys. 48:023302, [2007]), our result proves that in the
low density limit the leading order correction compared to the ground state energy
of a non-interacting lattice Fermi gas is given by 8πaσ uσ d , where σ u(d) denotes
the density of the spin-up (down) particles, and a is the scattering length of
the contact interaction potential. This result extends previous work on the corresponding
continuum model to the lattice case.

text: The Bardeen-Cooper-Schrieffer (BCS) functional has recently received renewed
attention as a description of fermionic gases interacting with local pairwise
interactions. We present here a rigorous analysis of the BCS functional for general
pair interaction potentials. For both zero and positive temperature, we show that
the existence of a non-trivial solution of the nonlinear BCS gap equation is equivalent
to the existence of a negative eigenvalue of a certain linear operator. From this
we conclude the existence of a critical temperature below which the BCS pairing
wave function does not vanish identically. For attractive potentials, we prove
that the critical temperature is non-zero and exponentially small in the strength
of the potential.

text: We determine the sharp constant in the Hardy inequality for fractional Sobolev
spaces. To do so, we develop a non-linear and non-local version of the ground
state representation, which even yields a remainder term. From the sharp Hardy
inequality we deduce the sharp constant in a Sobolev embedding which is optimal
in the Lorentz scale. In the appendix, we characterize the cases of equality in
the rearrangement inequality in fractional Sobolev spaces.

text: We show that the Lieb-Liniger model for one-dimensional bosons with repulsive
δ-function interaction can be rigorously derived via a scaling limit from a dilute
three-dimensional Bose gas with arbitrary repulsive interaction potential of finite
scattering length. For this purpose, we prove bounds on both the eigenvalues and
corresponding eigenfunctions of three-dimensional bosons in strongly elongated
traps and relate them to the corresponding quantities in the Lieb-Liniger model.
In particular, if both the scattering length a and the radius r of the cylindrical
trap go to zero, the Lieb-Liniger model with coupling constant g ∼ a/r 2 is derived.
Our bounds are uniform in g in the whole parameter range 0 ≤ g ≤ ∞, and apply
to the Hamiltonian for three-dimensional bosons in a spectral window of size ∼
r -2 above the ground state energy.

text: We study the relativistic electron-positron field at positive temperature
in the Hartree-Fock approximation. We consider both the case with and without
exchange terms, and investigate the existence and properties of minimizers. Our
approach is non-perturbative in the sense that the relevant electron subspace
is determined in a self-consistent way. The present work is an extension of previous
work by Hainzl, Lewin, Séré and Solovej where the case of zero temperature was
considered.

text: We study the disk containment problem introduced by Neumann-Lara and Urrutia
and its generalization to higher dimensions. We relate the problem to centerpoints
and lower centerpoints of point sets. Moreover, we show that for any set of n
points in ℝd, there is a subset A ⊆ S of size [d+3/2] such that any ball containing
A contains at least roughly 4/5ed 3n points of S. This improves previous bounds
for which the constant was exponentially small in d. We also consider a generalization
of the planar disk containment problem to families of pseudodisks.

text: Cyclic nucleotide phosphodiesterase 10A (PDE10A) is a member of phosphodiesterase
families that degrade cAMP and/or cGMP in distinct intracellular sites. PDE10A
has a dual activity on hydrolysis of both cAMP and cGMP, and is prominently expressed
in the striatum and the testis. Previous studies suggested that PDE10A is involved
in regulation of locomotor activity and potentially related to psychosis, but
concrete physiological roles of PDE10A remains elusive yet. In this study, we
genetically inactivated PDE10A2, a prominent isoform of PDE10A in the brain, in
mice, and demonstrate that PDE10A2 deficiency results in increased social interaction
without any major influence on different other behaviors, along with increased
levels of striatal cAMP. We also demonstrate that PDE10A2 is selectively distributed
in medium spiny neurons, but not interneurons, of the striatal complex. Thus,
our results establish a physiological role for PDE10A2 in regulating cAMP pathway
and social interaction, and suggest that cAMP signaling cascade in striatal medium
spiny neurons might be involved in regulating social interaction behavior in mice.

text: Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels that generate
Ih currents are widely distributed in the brain and have been shown to contribute
to various neuronal functions. In the present study, we investigated the functions
of Ih in the motion-sensitive projection neurons [wide field vertical (WFV) cells]
of the superior colliculus, a pivotal visual center for detection of and orientating
to salient objects. Combination of whole cell recordings and immunohistochemical
investigations suggested that HCN1 channels dominantly contribute to the Ih in
WFV cells among HCN isoforms expressed in the superficial superior colliculus
and mainly located on their expansive dendritic trees. We found that blocking
Ih suppressed the initiation of short- and fixed-latency dendritic spike responses
and led instead to long- and fluctuating-latency somatic spike responses to optic
fiber stimulations. These results suggest that the dendritic Ih facilitates the
dendritic initiation and/or propagation of action potentials and ensures that
WFV cells generate spike responses to distal synaptic inputs in a sensitive and
robustly time-locked manner, probably by acting as continuous depolarizing drive
and fixing dendritic membrane potentials close to the spike threshold. These functions
are different from known functions of dendritic Ih revealed in hippocampal and
neocortical pyramidal cells, where they spatiotemporally limit the propagations
of synaptic inputs along the apical dendrites by reducing dendritic membrane resistance.
Thus we have revealed new functional aspects of Ih, and these dendritic properties
are likely critical for visual motion processing in these neurons.

text: Left-right (L-R) asymmetry is a fundamental feature of higher-order neural
function. However, the molecular basis of brain asymmetry remains unclear. We
recently reported L-R asymmetry of hippocampal circuitry caused by differential
allocation of N-methyl-O-aspartate receptor (NMDAR) subunit GluRε2 (NR2B) in hippocambal
synapses. Using electrophysiology and immunocytochemistry, here we analyzed the
hippocampal circuitry of the inversus viscerum (iv) mouse that has a randomized
laterality of internal organs. The iv mouse hippocampus lacks L-R asymmetry, it
exhibits right isomerism in the synaptic distribution of the ε2 subunit, irrespective
of the laterality of visceral organs. This independent right isomerism of the
hippocampus is the first evidence that a distinct mechanism downstream of the
iv mutation generates brain asymmetry.

text: The medial septum (MS) is an indispensable component of the subcortical network
which synchronizes the hippocampus at theta frequency during specific stages of
information processing. GABAergic neurons exhibiting highly regular firing coupled
to the hippocampal theta rhythm are thought to form the core of the MS rhythm-generating
network. In recent studies the hyperpolarization-activated, cyclic nucleotide-gated
non-selective cation (HCN) channel was shown to participate in theta synchronization
of the medial septum. Here, we tested the hypothesis that HCN channel expression
correlates with theta modulated firing behaviour of MS neurons by a combined anatomical
and electrophysiological approach. HCN-expressing neurons represented a subpopulation
of GABAergic cells in the MS partly overlapping with parvalbumin (PV)-containing
neurons. Rhythmic firing in the theta frequency range was characteristic of all
HCN-expressing neurons. In contrast, only a minority of HCN-negative cells displayed
theta related activity. All HCN cells had tight phase coupling to hippocampal
theta waves. As a group, PV-expressing HCN neurons had a marked bimodal phase
distribution, whereas PV-immunonegative HCN neurons did not show group-level phase
preference despite significant individual phase coupling. Microiontophoretic blockade
of HCN channels resulted in the reduction of discharge frequency, but theta rhythmic
firing was perturbed only in a few cases. Our data imply that HCN-expressing GABAergic
neurons provide rhythmic drive in all phases of the hippocampal theta activity.
In most MS theta cells rhythm genesis is apparently determined by interactions
at the level of the network rather than by the pacemaking property of HCN channels
alone.

text: Mammalian retinas contain abundant neuronal gap junctions, particularly in
the inner plexiform layer (IPL), where the two principal neuronal connexin proteins
are Cx36 and Cx45. Currently undetermined are coupling relationships between these
connexins and whether both are expressed together or separately in a neuronal
subtype-specific manner. Although Cx45-expressing neurons strongly couple with
Cx36-expressing neurons, possibly via heterotypic gap junctions, Cx45 and Cx36
failed to form functional heterotypic channels in vitro. We now show that Cx36
and Cx45 coexpressed in HeLa cells were colocalized in immunofluorescent puncta
between contacting cells, demonstrating targeting/scaffolding competence for both
connexins in vitro. However, Cx36 and Cx45 expressed separately did not form immunofluorescent
puncta containing both connexins, supporting lack of heterotypic coupling competence.
In IPL, 87% of Cx45-immunofluorescent puncta were colocalized with Cx36, supporting
either widespread heterotypic coupling or bihomotypic coupling. Ultrastructurally,
Cx45 was detected in 9% of IPL gap junction hemiplaques, 90-100% of which also
contained Cx36, demonstrating connexin coexpression and cotargeting in virtually
all IPL neurons that express Cx45. Moreover, double replicas revealed both connexins
in separate domains mirrored on both sides of matched hemiplaques. With previous
evidence that Cx36 interacts with PDZ1 domain of zonula occludens-1 (ZO-1), we
show that Cx45 interacts with PDZ2 domain of ZO-1, and that Cx36, Cx45, and ZO-1
coimmunoprecipitate, suggesting that ZO-1 provides for coscaffolding of Cx45 with
Cx36. These data document that in Cx45-expressing neurons of IPL, Cx45 is almost
always accompanied by Cx36, forming "bihomotypic" gap junctions, with
Cx45 structurally coupling to Cx45 and Cx36 coupling to Cx36.

text: Ionotropic glutamate receptors play important roles in spinal processing of
nociceptive sensory signals and induction of central sensitization in chronic
pain. Here we applied highly sensitive freeze-fracture replica labeling to laminae
I-II of the spinal dorsal horn of rats and investigated the numbers, densities,
and colocalization of AMPA- and NMDA-type glutamate receptors at individual postsynaptic
membrane specializations with a high resolution. All glutamatergic postsynaptic
membranes in laminae I-II expressed AMPA receptors, and most of them (96%) were
also immunoreactive for the NR1 subunit of NMDA receptors. The numbers of gold
particles for AMPA and NMDA receptors at individual postsynaptic membranes showed
a linear correlation with the size of postsynaptic membrane specializations and
varied in the range of 8-214 and 5-232 with median values of 37 and 28, whereas
their densities varied in the range of 325-3365/μm 2 and 102-2263/μm 2 with median
values of 1115/μm 2 and 777/μm 2, respectively. Virtually all (99%) glutamatergic
postsynaptic membranes expressed GluR2, and most of them (87%) were also immunoreactive
for GluR1. The numbers of gold particles for pan-AMPA, NR1, and GluR2 subunits
showed a linear correlation with the size of postsynaptic surface areas. Concerning
GluR1, there may be two populations of synapses with high and low GluR1 densities.
In synapses larger than 0.1 μm 2, GluR1 subunits were recovered in very low numbers.
Differential expression of GluR1 and GluR2 subunits suggests regulation of AMPA
receptor subunit composition by presynaptic mechanism.

text: Left-right asymmetry of the brain has been studied mostly through psychological
examination and functional imaging in primates, leaving its molecular and synaptic
aspects largely unaddressed. Here, we show that hippocampal CA1 pyramidal cell
synapses differ in size, shape, and glutamate receptor expression depending on
the laterality of presynaptic origin. CA1 synapses receiving neuronal input from
the right CA3 pyramidal cells are larger and have more perforated PSD and a GluR1
expression level twice as high as those receiving input from the left CA3. The
synaptic density of GluR1 increases as the size of a synapse increases, whereas
that of NR2B decreases because of the relatively constant NR2B expression in CA1
regardless of synapse size. Densities of other major glutamate receptor subunits
show no correlation with synapse size, thus resulting in higher net expression
in synapses having right input. Our study demonstrates universal left-right asymmetry
of hippocampal synapses with a fundamental relationship between synaptic area
and the expression of glutamate receptor subunits.
