text: 'We resolve several longstanding problems concerning the stability and the
absence of multi-particle binding for N≥2 polarons. Fröhlich''s 1937 polaron model
describes non-relativistic particles interacting with a scalar quantized field
with coupling √α, and with each other by Coulomb repulsion of strength U. We prove
the following: (i) While there is a known thermodynamic instability for U<2α,
stability of matter does hold for U>2α, that is, the ground state energy per
particle has a finite limit as N→∞. (ii) There is no binding of any kind if U
exceeds a critical value that depends on α but not on N. The same results are
shown to hold for the Pekar-Tomasevich model.'

text: 'Let EMBEDk→d be the following algorithmic problem: Given a finite simplicial
complex K of dimension at most k, does there exist a (piecewise linear) embedding
of K into Rd? Known results easily imply the polynomiality of EMBEDk→2 (k = 1;
2; the case k = 1, d = 2 is graph planarity) and of EMBEDk→2k for all k ≥ 3. We
show that the celebrated result of Novikov on the algorithmic unsolvability of
recognizing the 5-sphere implies that EMBEDd→d and EMBED (d-1)→d are undecidable
for each d ≥ 5. Our main result is the NP-hardness of EMBED2→4 and, more generally,
of EMBED k→d for all k; d with d ≥ 4 and d ≥ k ≥ (2d - 2)/3. These dimensions
fall outside the metastable range of a theorem of Haefliger and Weber, which characterizes
embeddability using the deleted product obstruction. Our reductions are based
on examples, due to Segal, Spież, Freedman, Krushkal, Teichner, and Skopenkov,
showing that outside the metastable range the deleted product obstruction is not
sufficient to characterize embeddability. '

text: We introduce a new notion of minors for simplicial complexes (hypergraphs),
so-called homological minors. Our motivation is to propose a general approach
to attack certain extremal problems for sparse simplicial complexes and the corresponding
threshold problems for random complexes. In this paper, we focus on threshold
problems. The basic model for random complexes is the Linial-Meshulam model Xk(n,
p). By definition, such a complex has n vertices, a complete (k -1)-dimensional
skeleton, and every possible k-dimensional simplex is chosen independently with
probability p. We show that for every k, t≥ 1, there is a constant C = C(k, t)
such that for p≥ C/n, the random complex Xk(n, p) asymptotically almost surely
contains K tk (the complete k-dimensional complex on t vertices) as a homological
minor. As corollary, the threshold for (topological) embeddability of Xk(n, p)
into R2k is at p = θ(1/n). The method can be extended to other models of random
complexes (for which the lower skeleta are not necessarily complete) and also
to more general Tverberg-type problems, where instead of continuous maps without
doubly covered image points (embeddings), we consider maps without qfold covered
image points.

text: Within a multicellular tissue cells may coordinately form a singular or multiple
polar axes, but it is unclear whether a common mechanism governs different types
of polar axis formation. The phosphorylation status of PIN proteins, which is
directly affected by the PINOID (PID) protein kinase and the PP2A protein phosphatase,
is known to regulate the apical-basal polarity of PIN localization in bipolar
cells of roots and shoot apices. Here, we provide evidence that the phosphorylation
status-mediated PIN polarity switch is widely used to modulate cellular processes
in Arabidopsis including multipolar pavement cells (PC) with interdigitated lobes
and indentations. The degree of PC interdigitation was greatly reduced either
when the FYPP1 gene, which encodes a PP2A called phytochrome-associated serine/threonine
protein phosphatase, was knocked out or when the PID gene was overexpressed (35S:PID).
These genetic modifications caused PIN1 localization to switch from lobe to indentation
regions. The PP2A and PID mediated switching of PIN1 localization is strikingly
similar to their regulation of the apical-basal polarity switch of PIN proteins
in other cells. Our findings suggest a common mechanism for the regulation of
PIN1 polarity formation, a fundamental cellular process that is crucial for pattern
formation both at the tissue/organ and cellular levels.

text: In unicellular and multicellular organisms, cell polarity is essential for
a wide range of biological processes. An important feature of cell polarity is
the asymmetric distribution of proteins in or at the plasma membrane. In plants
such polar localized proteins play various specific roles ranging from organizing
cell morphogenesis, asymmetric cell division, pathogen defense, nutrient transport
and establishment of hormone gradients for developmental patterning. Moreover,
flexible respecification of cell polarities enables plants to adjust their physiology
and development to environmental changes. Having evolved multicellularity independently
and lacking major cell polarity mechanisms of animal cells, plants came up with
alternative solutions to generate and respecify cell polarity as well as to regulate
polar domains at the plasma membrane.

text: Parkinson's disease is a common neurodegenerative disorder characterized by
a profound motor disability that is traceable to the emergence of synchronous,
rhythmic spiking in neurons of the external segment of the globus pallidus (GPe).
The origins of this pathophysiology are poorly defined for the generation of pacemaking.
After the induction of a parkinsonian state in mice, there was a progressive decline
in autonomous GPe pacemaking, which normally serves to desynchronize activity.
The loss was attributable to the downregulation of an ion channel that is essential
in pacemaking, the hyperpolarization and cyclic nucleotide-gated (HCN) channel.
Viral delivery of HCN2 subunits restored pacemaking and reduced burst spiking
in GPe neurons. However, the motor disability induced by dopamine (DA) depletion
was not reversed, suggesting that the loss of pacemaking was a consequence, rather
than a cause, of key network pathophysiology, a conclusion that is consistent
with the ability of L-type channel antagonists to attenuate silencing after DA
depletion.

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: Consider the Dyson Brownian motion with parameter β, where β=1,2,4 corresponds
to the eigenvalue flows for the eigenvalues of symmetric, hermitian and quaternion
self-dual ensembles. For any β≥1, we prove that the relaxation time to local equilibrium
for the Dyson Brownian motion is bounded above by N -ζ for some ζ> 0. The proof
is based on an estimate of the entropy flow of the Dyson Brownian motion w. r.
t. a "pseudo equilibrium measure". As an application of this estimate,
we prove that the eigenvalue spacing statistics in the bulk of the spectrum for
N×N symmetric Wigner ensemble is the same as that of the Gaussian Orthogonal Ensemble
(GOE) in the limit N→∞. The assumptions on the probability distribution of the
matrix elements of the Wigner ensemble are a subexponential decay and some minor
restriction on the support.

text: 'This is a study of the universality of spectral statistics for large random
matrices. Considered are N×N symmetric, Hermitian, or quaternion self-dual random
matrices with independent identically distributed entries (Wigner matrices), where
the probability distribution of each matrix element is given by a measure v with
zero expectation and with subexponential decay. The main result is that the correlation
functions of the local eigenvalue statistics in the bulk of the spectrum coincide
with those of the Gaussian Orthogonal Ensemble (GOE), the Gaussian Unitary Ensemble
(GUE), and the Gaussian Symplectic Ensemble (GSE), respectively, in the limit
as N → ∞. This approach is based on a study of the Dyson Brownian motion via a
related new dynamics, the local relaxation flow. As a main input, it is established
that the density of the eigenvalues converges to the Wigner semicircle law, and
this holds even down to the smallest possible scale. Moreover, it is shown that
the eigenvectors are completely delocalized. These results hold even without the
condition that the matrix elements are identically distributed: only independence
is used. In fact, for the matrix elements of the Green function strong estimates
are given that imply that the local statistics of any two ensembles in the bulk
are identical if the first four moments of the matrix elements match. Universality
at the spectral edges requires matching only two moments. A Wigner-type estimate
is also proved, and it is shown that the eigenvalues repel each other on arbitrarily
small scales.'

text: We consider Hermitian and symmetric random band matrices H in d ≥ dimensions.
The matrix elements Hxy, indexed by x,y ∈ Λ ⊂ ℤd are independent and their variances
satisfy σ2xy:= E{pipe}Hxy{pipe}2 = W-d f((x-y)/W for some probability density
f. We assume that the law of each matrix element Hxy is symmetric and exhibits
subexponential decay. We prove that the time evolution of a quantum particle subject
to the Hamiltonian H is diffusive on time scales ≪ Wd/3. We also show that the
localization length of the eigenvectors of H is larger than a factor Wd/6 times
the band width W. All results are uniform in the size {pipe}Λ{pipe} of the matrix.
This extends our recent result (Erdo{double acute}s and Knowles in Commun. Math.
Phys., 2011) to general band matrices. As another consequence of our proof we
show that, for a larger class of random matrices satisfying Σx σ2xy for all y,
the largest eigenvalue of H is bounded with high probability by 2+M-2/3+e{open}
for any e{open} > 0, where M:= 1/(maxx,y σ2xy).

text: Shear flows undergo a sudden transition from laminar to turbulent motion as
the velocity increases, and the onset of turbulence radically changes transport
efficiency and mixing properties. Even for the well-studied case of pipe flow,
it has not been possible to determine at what Reynolds number the motion will
be either persistently turbulent or ultimately laminar. We show that in pipes,
turbulence that is transient at low Reynolds numbers becomes sustained at a distinct
critical point. Through extensive experiments and computer simulations, we were
able to identify and characterize the processes ultimately responsible for sustaining
turbulence. In contrast to the classical Landau-Ruelle-Takens view that turbulence
arises from an increase in the temporal complexity of fluid motion, here, spatial
proliferation of chaotic domains is the decisive process and intrinsic to the
nature of fluid turbulence.

text: In shear flows, turbulence first occurs in the form of localized structures
(puffs/spots) surrounded by laminar fluid. We here investigate such spatially
intermittent flows in a pipe experiment showing that turbulent puffs have a well-defined
interaction distance, which sets their minimum spacing as well as the maximum
observable turbulent fraction. Two methodologies are employed. Starting from a
laminar flow, puffs are first created by locally injecting a jet of fluid through
the pipe wall. When the perturbation is applied periodically at low frequencies,
as expected, a regular sequence of puffs is observed where the puff spacing is
given by the ratio of the mean flow speed to the perturbation frequency. At large
frequencies however puffs are found to interact and annihilate each other. Varying
the perturbation frequency, an interaction distance is determined which sets the
highest possible turbulence fraction. This enables us to establish an upper bound
for the friction factor in the transitional regime, which provides a well-defined
link between the Blasius and the Hagen-Poiseuille friction laws. In the second
set of experiments, the Reynolds number is reduced suddenly from fully turbulent
to the intermittent regime. The resulting flow reorganizes itself to a sequence
of constant size puffs which, unlike in Couette and Taylor–Couette flow are randomly
spaced. The minimum distance between the turbulent patches is identical to the
puff interaction length. The puff interaction length is found to be in agreement
with the wavelength of regular stripe and spiral patterns in plane Couette and
Taylor–Couette flow.

text: Turbulent puffs in pipe flow are characterized by a sharp laminar-turbulent
interface at the trailing edge and a more diffused leading interface. It is known
that these laminar-turbulent interfaces propagate at a speed that is approximately
equal to the flow rate. Our results from direct numerical simulation show that,
locally, the interface velocity relative to the fluid (i) counteracts the advection
due to the laminar velocity profile so that the puff can preserve its characteristic
overall shape, (ii) is very small in magnitude, but involves a large interface
area so that the global propagation velocity relative to the mean flow can be
large and (iii) is determined by both inertial and viscous effects. The analysis
provides some new insights into the mechanisms that sustain or expand localized
turbulence and might be relevant for the design of new control strategies.

text: Despite their relatively simple appearance, roots are incredibly complex organs
that are highly adapted to differing environments. Many aspects of root development
are co-ordinated by subtle spatial differences in the concentrations of the phytohormones
auxin and cytokinin. Events from the formation of a root during embryogenesis
to the determination of the network of lateral roots are controlled by interactions
between these hormones. Recently, interactions have been defined where auxin signaling
promotes the expression of cytokinin signaling inhibitors, cytokinin signaling
promotes the expression of auxin signaling inhibitors and finally where cytokinin
signaling regulates the complex network of auxin transport proteins to position
zones of high auxin signaling. We are witnessing a period of discovery in which
we are beginning to understand how these hormonal pathways communicate to regulate
root formation.

text: The apical hook develops in the upper part of the hypocotyl when seeds buried
in the soil germinate, and serves to protect cotyledons and the shoot apical meristem
from possible damage caused by pushing through the soil. The curvature is formed
through differential cell growth that occurs at the two opposite sides of the
hypocotyl, and it is established by a gradient of auxin activity and refined by
the coordinated action of auxin and ethylene. Here we show that gibberellins (GAs)
promote hook development through the transcriptional regulation of several genes
of the ethylene and auxin pathways in Arabidopsis. The level of GA activity determines
the speed of hook formation and the extent of the curvature during the formation
phase independently of ethylene, probably by modulating auxin transport and response
through HLS1, PIN3, and PIN7. Moreover, GAs cooperate with ethylene in preventing
hook opening, in part through the induction of ethylene production mediated by
ACS5/ETO2 and ACS8.
