text: Set agreement is a fundamental problem in distributed computing in which processes
collectively choose a small subset of values from a larger set of proposals. The
impossibility of fault-tolerant set agreement in asynchronous networks is one
of the seminal results in distributed computing. In synchronous networks, too,
the complexity of set agreement has been a significant research challenge that
has now been resolved. Real systems, however, are neither purely synchronous nor
purely asynchronous. Rather, they tend to alternate between periods of synchrony
and periods of asynchrony. Nothing specific is known about the complexity of set
agreement in such a "partially synchronous" setting. In this paper,
we address this challenge, presenting the first (asymptotically) tight bound on
the complexity of set agreement in such systems. We introduce a novel technique
for simulating, in a fault-prone asynchronous shared memory, executions of an
asynchronous and failure-prone message-passing system in which some fragments
appear synchronous to some processes. We use this simulation technique to derive
a lower bound on the round complexity of set agreement in a partially synchronous
system by a reduction from asynchronous wait-free set agreement. Specifically,
we show that every set agreement protocol requires at least $\lfloor\frac t k
\rfloor + 2$ synchronous rounds to decide. We present an (asymptotically) matching
algorithm that relies on a distributed asynchrony detection mechanism to decide
as soon as possible during periods of synchrony. From these two results, we derive
the size of the minimal window of synchrony needed to solve set agreement. By
relating synchronous, asynchronous and partially synchronous environments, our
simulation technique is of independent interest. In particular, it allows us to
obtain a new lower bound on the complexity of early deciding k-set agreement complementary
to that of Gafni et al. (in SIAM J. Comput. 40(1):63-78, 2011), and to re-derive
the combinatorial topology lower bound of Guerraoui et al. (in Theor. Comput.
Sci. 410(6-7):570-580, 2009) in an algorithmic way.

text: The Seebeck coefficients, electrical resistivities, total thermal conductivities,
and magnetization are reported for temperatures between 5 and 350 K for n-type
Bi0.88Sb0.12 nano-composite alloys made by Ho-doping at the 0, 1, and 3 % atomic
levels. The alloys were prepared using a dc hot-pressing method, and are shown
to be single phase for both Ho contents with grain sizes on the average of 900
nm. We find the parent compound has a maximum of ZT = 0.28 at 231 K, while doping
1 % Ho increases the maximum ZT to 0.31 at 221 K and the 3 % doped sample suppresses
the maximum ZT = 0.24 at a temperature of 260 K.

text: There is a long-running controversy about how early cell fate decisions are
made in the developing mammalian embryo. 1,2 In particular, it is controversial
when the first events that can predict the establishment of the pluripotent and
extra-embryonic lineages in the blastocyst of the pre-implantation embryo occur.
It has long been proposed that the position and polarity of cells at the 16- to
32-cell stage embryo influence their decision to either give rise to the pluripotent
cell lineage that eventually contributes to the inner cell mass (ICM), comprising
the primitive endoderm (PE) and the epiblast (EPI), or the extra-embryonic trophectoderm
(TE) surrounding the blastocoel. The positioning of cells in the embryo at this
developmental stage could largely be the result of random events, making this
a stochastic model of cell lineage allocation. Contrary to such a stochastic model,
some studies have detected putative differences in the lineage potential of individual
blastomeres before compaction, indicating that the first cell fate decisions may
occur as early as at the 4-cell stage. Using a non-invasive, quantitative in vivo
imaging assay to study the kinetic behavior of Oct4 (also known as POU5F1), a
key transcription factor (TF) controlling pre-implantation development in the
mouse embryo, 3-5 a recent study identifies Oct4 kinetics as a predictive measure
of cell lineage patterning in the early mouse embryo. 6 Here, we discuss the implications
of such molecular heterogeneities in early development and offer potential avenues
toward a mechanistic understanding of these observations, contributing to the
resolution of the controversy of developmental cell lineage allocation.

text: We made use of supersymmetric (SUSY) quantum mechanics to find the condition
under which the Stark effect problem for a polar and polarizable closed-shell
diatomic molecule subjected to collinear electrostatic and nonresonant radiative
fields becomes exactly solvable. The condition Δω = ω2/4(m+1)2 connects values
of the dimensionless parameters ω and Δω that characterize the strengths of the
permanent and induced dipole interactions of the molecule with the respective
fields. The exact solutions are obtained for the \J̃ = m, m; ω, Δω) family of
'stretched' states. The field-free and strong-field limits of the combined-fields
problem were found to exhibit supersymmetry and shape invariance, which is indeed
the reason why they are analytically solvable. By making use of the analytic form
of the \J̃ = m,m; ω, Δω) wavefunctions, we obtained simple formulae for the expectation
values of the space-fixed electric dipole moment, the alignment cosine and the
angular momentum squared, and derived a 'sum rule' that combines the above expectation
values into a formula for the eigenenergy. The analytic expressions for the characteristics
of the strongly oriented and aligned states provide direct access to the values
of the interaction parameters required for creating such states in the laboratory.

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).

A central question in developmental biology concerns the mechanism of generation and maintenance of cell polarity, because these processes are essential for many cellular functions and multicellular development [1]. In plants, cell polarity has an additional role in mediating directional transport of the plant hormone auxin that is crucial for multiple developmental processes [2-4]. In addition, plant cells have a complex extracellular matrix, the cell wall [5, 6], whose role in regulating cellular processes, including cell polarity, is unexplored. We have found that polar distribution of PIN auxin transporters [7] in plant cells is maintained by connections between polar domains at the plasma membrane and the cell wall. Genetic and pharmacological interference with cellulose, the major component of the cell wall, or mechanical interference with the cell wall disrupts these connections and leads to increased lateral diffusion and loss of polar distribution of PIN transporters for the phytohormone auxin. Our results reveal a plant-specific mechanism for cell polarity maintenance and provide a conceptual framework for modulating cell polarity and plant development via endogenous and environmental manipulations of the cellulose-based extracellular matrix.

text: Tumor necrosis factor-stimulated gene-6 (TSG-6) is a hyalu-ronan (HA)-binding
protein that plays important roles ininflammation and ovulation. TSG-6-mediated
cross-linking ofHA has been proposed as a functional mechanism (e.g.for regu-lating
leukocyte adhesion), but direct evidence for cross-linkingis lacking, and we know
very little about its impact on HA ultra-structure. Here we used films of polymeric
and oligomeric HAchains, end-grafted to a solid support, and a combination ofsurface-sensitive
biophysical techniques to quantify the bindingof TSG-6 into HA films and to correlate
binding to morpholog-ical changes. We find that full-length TSG-6 binds with pro-nounced
positive cooperativity and demonstrate that it cancross-link HA at physiologically
relevant concentrations. Ourdata indicate that cooperative binding of full-length
TSG-6arises from HA-induced protein oligomerization and that theTSG-6 oligomers
act as cross-linkers. In contrast, the HA-bind-ing domain of TSG-6 (the Link module)
alone binds withoutpositive cooperativity and weaker than the full-length protein.Both
the Link module and full-length TSG-6 condensed andrigidified HA films, and the
degree of condensation scaled withthe affinity between the TSG-6 constructs and
HA. We proposethat condensation is the result of protein-mediated HA cross-linking.
Our findings firmly establish that TSG-6 is a potent HAcross-linking agent and
might hence have important implica-tions for the mechanistic understanding of
the biological func-tion of TSG-6 (e.g.in inflammation).

text: The polarized transport of the phytohormone auxin [1], which is crucial for
the regulation of different stages of plant development [2, 3], depends on the
asymmetric plasma membrane distribution of the PIN-FORMED (PIN) auxin efflux carriers
[4, 5]. The PIN polar localization results from clathrin-mediated endocytosis
(CME) from the plasma membrane and subsequent polar recycling [6]. The Arabidopsis
genome encodes two groups of dynamin-related proteins (DRPs) that show homology
to mammalian dynamin - a protein required for fission of endocytic vesicles during
CME [7, 8]. Here we show by coimmunoprecipitation (coIP), bimolecular fluorescence
complementation (BiFC), and Förster resonance energy transfer (FRET) that members
of the DRP1 group closely associate with PIN proteins at the cell plate. Localization
and phenotypic analysis of novel drp1 mutants revealed a requirement for DRP1
function in correct PIN distribution and in auxin-mediated development. We propose
that rapid and specific internalization of PIN proteins mediated by the DRP1 proteins
and the associated CME machinery from the cell plate membranes during cytokinesis
is an important mechanism for proper polar PIN positioning in interphase cells.

text: Cationic antimicrobial peptides (CAMPs) selectively target bacterial membranes
by electrostatic interactions with negatively charged lipids. It turned out that
for inhibition of microbial growth a high CAMP membrane concentration is required,
which can be realized by the incorporation of hydrophobic groups within the peptide.
Increasing hydrophobicity, however, reduces the CAMP selectivity for bacterial
over eukaryotic host membranes, thereby causing the risk of detrimental side-effects.
In this study we addressed how cationic amphipathic peptides—in particular a CAMP
with Lysine–Leucine–Lysine repeats (termed KLK)—affect the localization and dynamics
of molecules in eukaryotic membranes. We found KLK to selectively inhibit the
endocytosis of a subgroup of membrane proteins and lipids by electrostatically
interacting with negatively charged sialic acid moieties. Ultrastructural characterization
revealed the formation of membrane invaginations representing fission or fusion
intermediates, in which the sialylated proteins and lipids were immobilized. Experiments
on structurally different cationic amphipathic peptides (KLK, 6-MO-LF11-322 and
NK14-2) indicated a cooperation of electrostatic and hydrophobic forces that selectively
arrest sialylated membrane constituents.

text: In this paper we present a novel approach for fast search of handwritten Arabic
word-parts within large lexicons. The algorithm runs through three steps to achieve
the required results. First it warps multiple appearances of each word-part in
the lexicon for embedding into the same euclidean space. The embedding is done
based on the warping path produced by the Dynamic Time Warping (DTW) process while
calculating the similarity distance. In the next step, all samples of different
word-parts are resampled uniformly to the same size. The kd-tree structure is
used to store all shapes representing word parts in the lexicon. Fast approximation
of k-nearest neighbors generates a short list of candidates to be presented to
the next step. In the third step, the Active-DTW [15] algorithm is used to examine
each sample in the short list and give final accurate results. We demonstrate
our method on a database of 23,500 images of word-parts extracted from the IFN/ENIT
database [6] and 22,000 images collected from 93 writers. Our method achieves
a speedup of 5 orders of magnitude over the exact method, at the cost of only
a 3.8% reduction in accuracy.

text: We consider N × N Hermitian random matrices with independent identically distributed
entries (Wigner matrices). The matrices are normalized so that the average spacing
between consecutive eigenvalues is of order 1/ N. Under suitable assumptions on
the distribution of the single matrix element, we first prove that, away from
the spectral edges, the empirical density of eigenvalues concentrates around the
Wigner semicircle law on energy scales η ≫ N -1. This result establishes the semicircle
law on the optimal scale and it removes a logarithmic factor from our previous
result [6]. We then show a Wegner estimate, i.e., that the averaged density of
states is bounded. Finally, we prove that the eigenvalues of a Wigner matrix repel
each other, in agreement with the universality conjecture.

text: We consider N ×N Hermitian Wigner random matrices H where the probabilitydensity
for each matrix element is given by the density v(x)=e-U(x). We prove that the
eigenvalue statistics in the bulk are given by the Dyson sine kernel provided
that U ∈ C 6(R{double-struck}) with at most polynomially growing derivatives and
v(x)≤C e-c(x) for x large. The proof is based upon an approximate time reversal
of the Dyson Brownian motion combined with the convergence of the eigenvalue density
to the Wigner semicircle law on short scales.

text: The phenomenon of matter-wave interference lies at the heart of quantum physics.
It has been observed in various contexts in the limit of non-interacting particles
as a single-particle effect. Here we observe and control matter-wave interference
whose evolution is driven by interparticle interactions. In a multi-path matter-wave
interferometer, the macroscopic manybody wave function of an interacting atomic
Bose-Einstein condensate develops a regular interference pattern, allowing us
to detect and directly visualize the effect of interaction-induced phase shifts.
We demonstrate control over the phase evolution by inhibiting interaction-induced
dephasing and by refocusing a dephased macroscopic matter wave in a spin-echo-type
experiment. Our results show that interactions in a many-body system lead to a
surprisingly coherent evolution, possibly enabling narrow-band and high-brightness
matterwave interferometers based on atom lasers.

text: Model checking transactional memories (TMs) is difficult because of the unbounded
number, length, and delay of concurrent transactions, as well as the unbounded
size of the memory. We show that, under certain conditions satisfied by most TMs
we know of, the model checking problem can be reduced to a finite-state problem,
and we illustrate the use of the method by proving the correctness of several
TMs, including two-phase locking, DSTM, and TL2. The safety properties we consider
include strict serializability and opacity; the liveness properties include obstruction
freedom, livelock freedom, and wait freedom. Our main contribution lies in the
structure of the proofs, which are largely automated and not restricted to the
TMs mentioned above. In a first step we show that every TM that enjoys certain
structural properties either violates a requirement on some program with two threads
and two shared variables, or satisfies the requirement on all programs. In the
second step, we use a model checker to prove the requirement for the TM applied
to a most general program with two threads and two variables. In the safety case,
the model checker checks language inclusion between two finite-state transition
systems, a nondeterministic transition system representing the given TM applied
to a most general program, and a deterministic transition system representing
a most liberal safe TM applied to the same program. The given TM transition system
is nondeterministic because a TM can be used with different contention managers,
which resolve conflicts differently. In the liveness case, the model checker analyzes
fairness conditions on the given TM transition system.

text: We prove two stability results for Lipschitz functions on triangulable, compact
metric spaces and consider applications of both to problems in systems biology.
Given two functions, the first result is formulated in terms of the Wasserstein
distance between their persistence diagrams and the second in terms of their total
persistence.

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.
