text: First we note that the best polynomial approximation to vertical bar x vertical
bar on the set, which consists of an interval on the positive half-axis and a
point on the negative half-axis, can be given by means of the classical Chebyshev
polynomials. Then we explore the cases when a solution of the related problem
on two intervals can be given in elementary functions.

text: This paper proposes a novel cooperative approach for two-hop amplify-and-forward
(A&F) relaying that exploits both the signal forwarded by the relay and the one
directly transmitted by the source in impulse-radio ultra-wideband (IR-UWB) systems.
Specifically, we focus on a non-coherent setup employing a double-differential
encoding scheme at the source node and a single differential demodulation at the
relay and destination. The log-likelihood ratio based decision rule is derived
at the destination node. A semi-analytical power allocation strategy is presented
by evaluating a closed-form expression for the effective signal to noise ratio
(SNR) at the destination, which is maximized by exhaustive search. Numerical simulations
show that the proposed system outperforms both the direct transmission with single
differential encoding and the non-cooperative multi-hop approach in different
scenarios.

text: We report numerical simulations of membrane tubulation driven by large colloidal
particles. Using Monte Carlo simulations we study how the process depends on particle
size and binding strength, and present accurate free energy calculations to sort
out how tube formation compares with the competing budding process. We find that
tube formation is a result of the collective behavior of the particles adhering
on the surface, and it occurs for binding strengths that are smaller than those
required for budding. We also find that long linear aggregates of particles forming
on the membrane surface act as nucleation seeds for tubulation by lowering the
free energy barrier associated to the process.

text: Using computer simulations, we show that lipid membranes can mediate linear
aggregation of spherical nanoparticles binding to it for a wide range of biologically
relevant bending rigidities. This result is in net contrast with the isotropic
aggregation of nanoparticles on fluid interfaces or the expected clustering of
isotropic insertions in biological membranes. We present a phase diagram indicating
where linear aggregation is expected and compute explicitly the free-energy barriers
associated with linear and isotropic aggregation. Finally, we provide simple scaling
arguments to explain this phenomenology.

text: In July, 2011, a 32-year-old man presented with thoracic pain radiating to
the left arm and upper dorsum, shortness of breath, and palpitations. He had had
upper back tension for 6 months. Medical history was unremarkable apart from moderate
nicotine use (two pack-years). Echocardiography, electrocardiography, and laboratory
tests were unremarkable, excluding a cardiac event. CT of the chest after chest
radiography showed a large bulla of 16 cm diameter in the right hemithorax (figure
A). We did not detect radiological evidence of underlying pulmonary disease. The
bulla wall was unremarkable and no structures were seen within the bulla.

text: We prepare and study a metastable attractive Mott-insulator state formed with
bosonic atoms in a three-dimensional optical lattice. Starting from a Mott insulator
with Cs atoms at weak repulsive interactions, we use a magnetic Feshbach resonance
to tune the interactions to large attractive values and produce a metastable state
pinned by attractive interactions with a lifetime on the order of 10 s. We probe
the (de)excitation spectrum via lattice modulation spectroscopy, measuring the
interaction dependence of two- and three-body bound-state energies. As a result
of increased on-site three-body loss we observe resonance broadening and suppression
of tunneling processes that produce three-body occupation.

text: The goal of this work is to study the superconducting coherence length in
the fluctuation regime in cuprate superconductors. In this work we present cantilever
torque magnetometry measurements of micron-size BSCCO flakes patterned with arrays
of nanometer scale rings or holes. Using ultrasensitive dynamic torque magnetometry,
oscillations in magnetization are observed near Tc as a function of the applied
magnetic flux threading the array. Special effort was made to detect the oscillations
in magnetization at temperatures above Tc, where the Nernst effect and magnetization
measurements suggest the possibility of pairing. To constrain the magnitude of
the coherence length in the fluctuation regime, we will present the dependence
of the amplitude of the h/2e period oscillations as a function of temperature
and hole size.

text: The Arabidopsis thaliana central cell, the companion cell of the egg, undergoes
DNA demethylation before fertilization, but the targeting preferences, mechanism,
and biological significance of this process remain unclear. Here, we show that
active DNA demethylation mediated by the DEMETER DNA glycosylase accounts for
all of the demethylation in the central cell and preferentially targets small,
AT-rich, and nucleosome-depleted euchromatic transposable elements. The vegetative
cell, the companion cell of sperm, also undergoes DEMETER-dependent demethylation
of similar sequences, and lack of DEMETER in vegetative cells causes reduced small
RNA–directed DNA methylation of transposons in sperm. Our results demonstrate
that demethylation in companion cells reinforces transposon methylation in plant
gametes and likely contributes to stable silencing of transposable elements across
generations.

text: The regulation of eukaryotic chromatin relies on interactions between many
epigenetic factors, including histone modifications, DNA methylation, and the
incorporation of histone variants. H2A.Z, one of the most conserved but enigmatic
histone variants that is enriched at the transcriptional start sites of genes,
has been implicated in a variety of chromosomal processes. Recently, we reported
a genome-wide anticorrelation between H2A.Z and DNA methylation, an epigenetic
hallmark of heterochromatin that has also been found in the bodies of active genes
in plants and animals. Here, we investigate the basis of this anticorrelation
using a novel h2a.z loss-of-function line in Arabidopsis thaliana. Through genome-wide
bisulfite sequencing, we demonstrate that loss of H2A.Z in Arabidopsis has only
a minor effect on the level or profile of DNA methylation in genes, and we propose
that the global anticorrelation between DNA methylation and H2A.Z is primarily
caused by the exclusion of H2A.Z from methylated DNA. RNA sequencing and genomic
mapping of H2A.Z show that H2A.Z enrichment across gene bodies, rather than at
the TSS, is correlated with lower transcription levels and higher measures of
gene responsiveness. Loss of H2A.Z causes misregulation of many genes that are
disproportionately associated with response to environmental and developmental
stimuli. We propose that H2A.Z deposition in gene bodies promotes variability
in levels and patterns of gene expression, and that a major function of genic
DNA methylation is to exclude H2A.Z from constitutively expressed genes.

text: EMBRYONIC FLOWER1 (EMF1) is a plant-specific gene crucial to Arabidopsis vegetative
development. Loss of function mutants in the EMF1 gene mimic the phenotype caused
by mutations in Polycomb Group protein (PcG) genes, which encode epigenetic repressors
that regulate many aspects of eukaryotic development. In Arabidopsis, Polycomb
Repressor Complex 2 (PRC2), made of PcG proteins, catalyzes trimethylation of
lysine 27 on histone H3 (H3K27me3) and PRC1-like proteins catalyze H2AK119 ubiquitination.
Despite functional similarity to PcG proteins, EMF1 lacks sequence homology with
known PcG proteins; thus, its role in the PcG mechanism is unclear. To study the
EMF1 functions and its mechanism of action, we performed genome-wide mapping of
EMF1 binding and H3K27me3 modification sites in Arabidopsis seedlings. The EMF1
binding pattern is similar to that of H3K27me3 modification on the chromosomal
and genic level. ChIPOTLe peak finding and clustering analyses both show that
the highly trimethylated genes also have high enrichment levels of EMF1 binding,
termed EMF1_K27 genes. EMF1 interacts with regulatory genes, which are silenced
to allow vegetative growth, and with genes specifying cell fates during growth
and differentiation. H3K27me3 marks not only these genes but also some genes that
are involved in endosperm development and maternal effects. Transcriptome analysis,
coupled with the H3K27me3 pattern, of EMF1_K27 genes in emf1 and PRC2 mutants
showed that EMF1 represses gene activities via diverse mechanisms and plays a
novel role in the PcG mechanism.

text: Accumulating evidence points toward diverse functions for plant chromatin.
Remarkable progress has been made over the last few years in elucidating the mechanisms
for a number of these functions. Activity of the histone demethylase IBM1 accurately
targets DNA methylation to silent repeats and transposable elements, not to genes.
A genetic screen uncovered the surprising role of H2A.Z-containing nucleosomes
in sensing precise differences in ambient temperature and consequent gene regulation.
Precise maintenance of chromosome number is assured by a histone modification
that suppresses inappropriate DNA replication and by centromeric histone H3 regulation
of chromosome segregation. Histones and noncoding RNAs regulate FLOWERING LOCUS
C, the expression of which quantitatively measures the duration of cold exposure,
functioning as memory of winter. These findings are a testament to the power of
using plants to research chromatin organization, and demonstrate examples of how
chromatin functions to achieve biological accuracy, precision, and memory.

text: The most well-studied function of DNA methylation in eukaryotic cells is the
transcriptional silencing of genes and transposons. More recent results showed
that many eukaryotes methylate the bodies of genes as well and that this methylation
correlates with transcriptional activity rather than repression. The purpose of
gene body methylation remains mysterious, but is potentially related to the histone
variant H2A.Z. Studies in plants and animals have shown that the genome-wide distributions
of H2A.Z and DNA methylation are strikingly anticorrelated. Furthermore, we and
other investigators have shown that this relationship is likely to be the result
of an ancient but unknown mechanism by which DNA methylation prevents the incorporation
of H2A.Z. Recently, we discovered strong correlations between the presence of
H2A.Z within gene bodies, the degree to which a gene's expression varies across
tissue types or environmental conditions, and transcriptional misregulation in
an h2a.z mutant. We propose that one basal function of gene body methylation is
the establishment of constitutive expression patterns within housekeeping genes
by excluding H2A.Z from their bodies.

text: Motivated by recent experiments on Ba3NiSb2O 9, we investigate possible quantum
spin liquid ground states for spin S=1 Heisenberg models on the triangular lattice.
We use variational Monte Carlo techniques to calculate the energies of microscopic
spin liquid wave functions where spin is represented by three flavors of fermionic
spinon operators. These energies are compared with the energies of various competing
three-sublattice ordered states. Our approach shows that the antiferromagnetic
Heisenberg model with biquadratic term and single-ion anisotropy does not have
a low-temperature spin liquid phase. However, for an SU(3)-invariant model with
sufficiently strong ring-exchange terms, we find a paired chiral quantum spin
liquid with a Fermi surface of deconfined spinons that is stable against all types
of ordering patterns we considered. We discuss the physics of this exotic spin
liquid state in relation to the recent experiment and suggest new ways to test
this scenario.

text: Due to the omnipresent risk of epidemics, insect societies have evolved sophisticated
disease defences at the individual and colony level. An intriguing yet little
understood phenomenon is that social contact to pathogen-exposed individuals reduces
susceptibility of previously naive nestmates to this pathogen. We tested whether
such social immunisation in Lasius ants against the entomopathogenic fungus Metarhizium
anisopliae is based on active upregulation of the immune system of nestmates following
contact to an infectious individual or passive protection via transfer of immune
effectors among group members—that is, active versus passive immunisation. We
found no evidence for involvement of passive immunisation via transfer of antimicrobials
among colony members. Instead, intensive allogrooming behaviour between naive
and pathogen-exposed ants before fungal conidia firmly attached to their cuticle
suggested passage of the pathogen from the exposed individuals to their nestmates.
By tracing fluorescence-labelled conidia we indeed detected frequent pathogen
transfer to the nestmates, where they caused low-level infections as revealed
by growth of small numbers of fungal colony forming units from their dissected
body content. These infections rarely led to death, but instead promoted an enhanced
ability to inhibit fungal growth and an active upregulation of immune genes involved
in antifungal defences (defensin and prophenoloxidase, PPO). Contrarily, there
was no upregulation of the gene cathepsin L, which is associated with antibacterial
and antiviral defences, and we found no increased antibacterial activity of nestmates
of fungus-exposed ants. This indicates that social immunisation after fungal exposure
is specific, similar to recent findings for individual-level immune priming in
invertebrates. Epidemiological modeling further suggests that active social immunisation
is adaptive, as it leads to faster elimination of the disease and lower death
rates than passive immunisation. Interestingly, humans have also utilised the
protective effect of low-level infections to fight smallpox by intentional transfer
of low pathogen doses (“variolation” or “inoculation”).

text: To fight infectious diseases, host immune defences are employed at multiple
levels. Sanitary behaviour, such as pathogen avoidance and removal, acts as a
first line of defence to prevent infection [1] before activation of the physiological
immune system. Insect societies have evolved a wide range of collective hygiene
measures and intensive health care towards pathogen-exposed group members [2].
One of the most common behaviours is allogrooming, in which nestmates remove infectious
particles from the body surfaces of exposed individuals [3]. Here we show that,
in invasive garden ants, grooming of fungus-exposed brood is effective beyond
the sheer mechanical removal of fungal conidiospores as it also includes chemical
disinfection through the application of poison produced by the ants themselves.
Formic acid is the main active component of the poison. It inhibits fungal growth
of conidiospores remaining on the brood surface after grooming and also those
collected in the mouth of the grooming ant. This dual function is achieved by
uptake of the poison droplet into the mouth through acidopore self-grooming and
subsequent application onto the infectious brood via brood grooming. This extraordinary
behaviour extends current understanding of grooming and the establishment of social
immunity in insect societies.

text: 'We propose a two-step procedure for estimating multiple migration rates in
an approximate Bayesian computation (ABC) framework, accounting for global nuisance
parameters. The approach is not limited to migration, but generally of interest
for inference problems with multiple parameters and a modular structure (e.g.
independent sets of demes or loci). We condition on a known, but complex demographic
model of a spatially subdivided population, motivated by the reintroduction of
Alpine ibex (Capra ibex) into Switzerland. In the first step, the global parameters
ancestral mutation rate and male mating skew have been estimated for the whole
population in Aeschbacher et al. (Genetics 2012; 192: 1027). In the second step,
we estimate in this study the migration rates independently for clusters of demes
putatively connected by migration. For large clusters (many migration rates),
ABC faces the problem of too many summary statistics. We therefore assess by simulation
if estimation per pair of demes is a valid alternative. We find that the trade-off
between reduced dimensionality for the pairwise estimation on the one hand and
lower accuracy due to the assumption of pairwise independence on the other depends
on the number of migration rates to be inferred: the accuracy of the pairwise
approach increases with the number of parameters, relative to the joint estimation
approach. To distinguish between low and zero migration, we perform ABC-type model
comparison between a model with migration and one without. Applying the approach
to microsatellite data from Alpine ibex, we find no evidence for substantial gene
flow via migration, except for one pair of demes in one direction.'

text: The physical distance between presynaptic Ca2+ channels and the Ca2+ sensors
that trigger exocytosis of neurotransmitter-containing vesicles is a key determinant
of the signalling properties of synapses in the nervous system. Recent functional
analysis indicates that in some fast central synapses, transmitter release is
triggered by a small number of Ca2+ channels that are coupled to Ca2+ sensors
at the nanometre scale. Molecular analysis suggests that this tight coupling is
generated by protein–protein interactions involving Ca2+ channels, Ca2+ sensors
and various other synaptic proteins. Nanodomain coupling has several functional
advantages, as it increases the efficacy, speed and energy efficiency of synaptic
transmission.

text: Computing the topology of an algebraic plane curve C means computing a combinatorial
graph that is isotopic to C and thus represents its topology in R2. We prove that,
for a polynomial of degree n with integer coefficients bounded by 2ρ, the topology
of the induced curve can be computed with bit operations ( indicates that we
omit logarithmic factors). Our analysis improves the previous best known complexity
bounds by a factor of n2. The improvement is based on new techniques to compute
and refine isolating intervals for the real roots of polynomials, and on the consequent
amortized analysis of the critical fibers of the algebraic curve.

text: 'We consider two-player stochastic games played on a finite state space for
an infinite number of rounds. The games are concurrent: in each round, the two
players (player 1 and player 2) choose their moves independently and simultaneously;
the current state and the two moves determine a probability distribution over
the successor states. We also consider the important special case of turn-based
stochastic games where players make moves in turns, rather than concurrently.
We study concurrent games with \omega-regular winning conditions specified as
parity objectives. The value for player 1 for a parity objective is the maximal
probability with which the player can guarantee the satisfaction of the objective
against all strategies of the opponent. We study the problem of continuity and
robustness of the value function in concurrent and turn-based stochastic parity
gameswith respect to imprecision in the transition probabilities. We present quantitative
bounds on the difference of the value function (in terms of the imprecision of
the transition probabilities) and show the value continuity for structurally equivalent
concurrent games (two games are structurally equivalent if the support of the
transition function is same and the probabilities differ). We also show robustness
of optimal strategies for structurally equivalent turn-based stochastic parity
games. Finally we show that the value continuity property breaks without the structurally
equivalent assumption (even for Markov chains) and show that our quantitative
bound is asymptotically optimal. Hence our results are tight (the assumption is
both necessary and sufficient) and optimal (our quantitative bound is asymptotically
optimal).'

text: The ample chemical and structural freedom of quaternary compounds permits
engineering materials that fulfill the requirements of a wide variety of applications.
In this work, the mechanisms to achieve unprecedented size, shape, and composition
control in quaternary nanocrystals are detailed. The described procedure allows
obtaining tetrahedral and penta-tetrahedral quaternary nanocrystals with tuned
size distributions and controlled compositions from a plethora of I 2-II-IV-VI
4 semiconductors.
