text: In this Letter, we explore experimentally the phase behavior of a dense active
suspension of self-propelled colloids. In addition to a solidlike and gaslike
phase observed for high and low densities, a novel cluster phase is reported at
intermediate densities. This takes the form of a stationary assembly of dense
aggregates—resulting from a permanent dynamical merging and separation of active
colloids—whose average size grows with activity as a linear function of the self-propelling
velocity. While different possible scenarios can be considered to account for
these observations—such as a generic velocity weakening instability recently put
forward—we show that the experimental results are reproduced mathematically by
a chemotactic aggregation mechanism, originally introduced to account for bacterial
aggregation and accounting here for diffusiophoretic chemical interaction between
colloidal swimmers.

text: 'We demonstrate how to appropriately estimate the zero-frequency (static)
hyperpolarizability of an organic molecule from its charge distribution, and we
explore applications of these estimates for identifying and evaluating new organic
nonlinear optical (NLO) materials. First, we calculate hyperpolarizabilities from
Hartree-Fock-derived charge distributions and find order-of-magnitude agreement
with experimental values. We show that these simple arithmetic calculations will
enable systematic searches for new organic NLO molecules. Second, we derive hyperpolarizabilities
from crystallographic data using a multipolar charge-density analysis and find
good agreement with empirical calculations. This demonstrates an experimental
determination of the full static hyperpolarizability tensor in a solid-state sample. '

text: "In models of radiative–convective equilibrium it is known that convection
can spontaneously aggregate into one single localized moist region if the domain
is large enough. The large changes in the mean climate state and radiative fluxes
accompanying this self-aggregation raise questions as to what simulations at lower
resolutions with parameterized convection, in similar homogeneous geometries,
should be expected to produce to be considered successful in mimicking a cloud-resolving
model.\r\nThe authors investigate this self-aggregation in a nonrotating, three-dimensional
cloud-resolving model on a square domain without large-scale forcing. It is found
that self-aggregation is sensitive not only to the domain size, but also to the
horizontal resolution. With horizontally homogeneous initial conditions, convective
aggregation only occurs on domains larger than about 200km and with resolutions
coarser than about 2km in the model examined. The system exhibits hysteresis,
so that with aggregated initial conditions, convection remains aggregated even
at our finest resolution, 500m, as long as the domain is greater than 200–300km.\r\nThe
sensitivity of self-aggregation to resolution and domain size in this model is
due to the sensitivity of the distribution of low clouds to these two parameters.
Indeed, the mechanism responsible for the aggregation of convection is the dynamical
response to the longwave radiative cooling from low clouds. Strong longwave cooling
near cloud top in dry regions forces downward motion, which by continuity generates
inflow near cloud top and near-surface outflow from dry regions. This circulation
results in the net export of moist static energy from regions with low moist static
energy, yielding a positive feedback."

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 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: 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: 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: '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: 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.

f:I→I whose number of periodic points Pn(f)=∣{x∈I:fnx=x}∣ grows faster than any
ahead given sequence along a subsequence nk=3k. This example also shows that ‘non-flatness’
of critical points is necessary for the Martens–de Melo–van Strien theorem [M.

text: A subject of extensive study in evolutionary theory has been the issue of
how neutral, redundant copies can be maintained in the genome for long periods
of time. Concurrently, examples of adaptive gene duplications to various environmental
conditions in different species have been described. At this point, it is too
early to tell whether or not a substantial fraction of gene copies have initially
achieved fixation by positive selection for increased dosage. Nevertheless, enough
examples have accumulated in the literature that such a possibility should be
considered. Here, I review the recent examples of adaptive gene duplications and
make an attempt to draw generalizations on what types of genes may be particularly
prone to be selected for under certain environmental conditions. The identification
of copy-number variation in ecological field studies of species adapting to stressful
or novel environmental conditions may improve our understanding of gene duplications
as a mechanism of adaptation and its relevance to the long-term persistence of
gene duplications.

text: 'Diffusiophoretic motion of colloids and macromolecules under salt gradients
exhibits a logarithmic-sensing, i.e. the particle velocity is proportional to
the spatial gradient of the logarithm of the salt concentration, as VDP = DDP∇logc.
Here we explore experimentally the implications of this log-sensing behavior,
on the basis of a hydrogel microfluidic device allowing to build spatially and
temporally controlled gradients. We first demonstrate that the non-linearity of
the salt-taxis leads to a trapping of particles under concentration gradient oscillations
via a rectification of the motion. As an alternative, we make use of the high
sensitivity of diffusiophoretic migration to vanishing salt concentration due
to the log-sensing: in a counter-intuitive way, a vanishing gradient can lead
to measurable velocity provided that the solute concentration is low enough, thus
keeping ∇c/c finite. We show that this leads to a strong segregation of particles
in osmotic shock configuration, resulting from a step change of the salt concentration
at the boundaries. These various phenomena are rationalized on the basis of a
theoretical description for the time-dependent Smoluchowski equation for the colloidal
density.'

text: 'We study theoretically the morphologies of biological tubes affected by various
pathologies. When epithelial cells grow, the negative tension produced by their
division provokes a buckling instability. Several shapes are investigated: varicose,
dilated, sinuous, or sausagelike. They are all found in pathologies of tracheal,
renal tubes, or arteries. The final shape depends crucially on the mechanical
parameters of the tissues: Young''s modulus, wall-to-lumen ratio, homeostatic
pressure. We argue that since tissues must be in quasistatic mechanical equilibrium,
abnormal shapes convey information as to what causes the pathology. We calculate
a phase diagram of tubular instabilities which could be a helpful guide for investigating
the underlying genetic regulation.'

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: 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: 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: 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: Little is known about the stability of trophic relationships in complex natural
communities over evolutionary timescales. Here, we use sequence data from 18 nuclear
loci to reconstruct and compare the intraspecific histories of major Pleistocene
refugial populations in the Middle East, the Balkans and Iberia in a guild of
four Chalcid parasitoids (Cecidostiba fungosa, Cecidostiba semifascia, Hobbya
stenonota and Mesopolobus amaenus) all attacking Cynipid oak galls. We develop
a likelihood method to numerically estimate models of divergence between three
populations from multilocus data. We investigate the power of this framework on
simulated data, and-using triplet alignments of intronic loci-quantify the support
for all possible divergence relationships between refugial populations in the
four parasitoids. Although an East to West order of population divergence has
highest support in all but one species, we cannot rule out alternative population
tree topologies. Comparing the estimated times of population splits between species,
we find that one species, M. amaenus, has a significantly older history than the
rest of the guild and must have arrived in central Europe at least one glacial
cycle prior to other guild members. This suggests that although all four species
may share a common origin in the East, they expanded westwards into Europe at
different times. © 2012 Blackwell Publishing Ltd.

text: We show that diamagnetic particles can be remotely manipulated by a magnet
by the reversible adsorption of dual-responsive, light-switchable/superparamagnetic
nanoparticles down to their surface. Adsorption occurs upon exposure to UV light,
and can be reversed thermally or by ambient light. The dynamic self-assembly of
thin films of the dual-responsive nanoparticles induces attractive interactions
between diamagnetic particles. We demonstrate that catalytic amounts of the dual-responsive
nanoparticles are sufficient to magnetically guide and deliver the diamagnetic
particles to desired locations, where they can then be released by disassembling
the dynamic layers of superparamagnetic nanoparticles with visible light.

text: Well-defined metallic nanobowls can be prepared by extending the concept of
a protecting group to colloidal synthesis. Magnetic nanoparticles are employed
as “protecting groups” during the galvanic replacement of silver with gold. The
replacement reaction is accompanied by spontantous dissociation of the protecting
groups, leaving behind metallic nanobowls.

text: We propose a logic-based framework for automated reasoning about sequential
programs manipulating singly-linked lists and arrays with unbounded data. We introduce
the logic SLAD, which allows combining shape constraints, written in a fragment
of Separation Logic, with data and size constraints. We address the problem of
checking the entailment between SLAD formulas, which is crucial in performing
pre-post condition reasoning. Although this problem is undecidable in general
for SLAD, we propose a sound and powerful procedure that is able to solve this
problem for a large class of formulas, beyond the capabilities of existing techniques
and tools. We prove that this procedure is complete, i.e., it is actually a decision
procedure for this problem, for an important fragment of SLAD including known
decidable logics. We implemented this procedure and shown its preciseness and
its efficiency on a significant benchmark of formulas.

text: "Energy games belong to a class of turn-based two-player infinite-duration
games played on a weighted directed graph. It is one of the rare and intriguing
combinatorial problems that lie in NP ∩ co−NP, but are not known to be in P. While
the existence of polynomial-time algorithms has been a major open problem for
decades, there is no algorithm that solves any non-trivial subclass in polynomial
time.\r\nIn this paper, we give several results based on the weight structures
of the graph. First, we identify a notion of penalty and present a polynomial-time
algorithm when the penalty is large. Our algorithm is the first polynomial-time
algorithm on a large class of weighted graphs. It includes several counter examples
that show that many previous algorithms, such as value iteration and random facet
algorithms, require at least sub-exponential time. Our main technique is developing
the first non-trivial approximation algorithm and showing how to convert it to
an exact algorithm. Moreover, we show that in a practical case in verification
where weights are clustered around a constant number of values, the energy game
problem can be solved in polynomial time. We also show that the problem is still
as hard as in general when the clique-width is bounded or the graph is strongly
ergodic, suggesting that restricting graph structures need not help."

text: Many infinite state systems can be seen as well-structured transition systems
(WSTS), i.e., systems equipped with a well-quasi-ordering on states that is also
a simulation relation. WSTS are an attractive target for formal analysis because
there exist generic algorithms that decide interesting verification problems for
this class. Among the most popular algorithms are acceleration-based forward analyses
for computing the covering set. Termination of these algorithms can only be guaranteed
for flattable WSTS. Yet, many WSTS of practical interest are not flattable and
the question whether any given WSTS is flattable is itself undecidable. We therefore
propose an analysis that computes the covering set and captures the essence of
acceleration-based algorithms, but sacrifices precision for guaranteed termination.
Our analysis is an abstract interpretation whose abstract domain builds on the
ideal completion of the well-quasi-ordered state space, and a widening operator
that mimics acceleration and controls the loss of precision of the analysis. We
present instances of our framework for various classes of WSTS. Our experience
with a prototype implementation indicates that, despite the inherent precision
loss, our analysis often computes the precise covering set of the analyzed system.

text: Colorectal tumours that are wild type for KRAS are often sensitive to EGFR
blockade, but almost always develop resistance within several months of initiating
therapy. The mechanisms underlying this acquired resistance to anti-EGFR antibodies
are largely unknown. This situation is in marked contrast to that of small-molecule
targeted agents, such as inhibitors of ABL, EGFR, BRAF and MEK, in which mutations
in the genes encoding the protein targets render the tumours resistant to the
effects of the drugs. The simplest hypothesis to account for the development of
resistance to EGFR blockade is that rare cells with KRAS mutations pre-exist at
low levels in tumours with ostensibly wild-type KRAS genes. Although this hypothesis
would seem readily testable, there is no evidence in pre-clinical models to support
it, nor is there data from patients. To test this hypothesis, we determined whether
mutant KRAS DNA could be detected in the circulation of 28 patients receiving
monotherapy with panitumumab, a therapeutic anti-EGFR antibody. We found that
9 out of 24 (38%) patients whose tumours were initially KRAS wild type developed
detectable mutations in KRAS in their sera, three of which developed multiple
different KRAS mutations. The appearance of these mutations was very consistent,
generally occurring between 5 and 6months following treatment. Mathematical modelling
indicated that the mutations were present in expanded subclones before the initiation
of panitumumab treatment. These results suggest that the emergence of KRAS mutations
is a mediator of acquired resistance to EGFR blockade and that these mutations
can be detected in a non-invasive manner. They explain why solid tumours develop
resistance to targeted therapies in a highly reproducible fashion.

text: "Many scenarios in the living world, where individual organisms compete for
winning positions (or resources), have properties of auctions. Here we study the
evolution of bids in biological auctions. For each auction, n individuals are
drawn at random from a population of size N. Each individual makes a bid which
entails a cost. The winner obtains a benefit of a certain value. Costs and benefits
are translated into reproductive success (fitness). Therefore, successful bidding
strategies spread in the population. We compare two types of auctions. In “biological
all-pay auctions”, the costs are the bid for every participating individual. In
“biological second price all-pay auctions”, the cost for everyone other than the
winner is the bid, but the cost for the winner is the second highest bid. Second
price all-pay auctions are generalizations of the “war of attrition” introduced
by Maynard Smith. We study evolutionary dynamics in both types of auctions. We
calculate pairwise invasion plots and evolutionarily stable distributions over
the continuous strategy space. We find that the average bid in second price all-pay
auctions is higher than in all-pay auctions, but the average cost for the winner
is similar in both auctions. In both cases, the average bid is a declining function
of the number of participants, n. The more individuals participate in an auction
the smaller is the chance of winning, and thus expensive bids must be avoided.\r\n"

text: CA3 pyramidal neurons are important for memory formation and pattern completion
in the hippocampal network. It is generally thought that proximal synapses from
the mossy fibers activate these neurons most efficiently, whereas distal inputs
from the perforant path have a weaker modulatory influence. We used confocally
targeted patch-clamp recording from dendrites and axons to map the activation
of rat CA3 pyramidal neurons at the subcellular level. Our results reveal two
distinct dendritic domains. In the proximal domain, action potentials initiated
in the axon backpropagate actively with large amplitude and fast time course.
In the distal domain, Na+ channel–mediated dendritic spikes are efficiently initiated
by waveforms mimicking synaptic events. CA3 pyramidal neuron dendrites showed
a high Na+-to-K+ conductance density ratio, providing ideal conditions for active
backpropagation and dendritic spike initiation. Dendritic spikes may enhance the
computational power of CA3 pyramidal neurons in the hippocampal network.

text: 'CA3 pyramidal neurons are important for memory formation and pattern completion
in the hippocampal network. These neurons receive multiple excitatory inputs from
numerous sources. Therefore, the rules of spatiotemporal integration of multiple
synaptic inputs and propagation of action potentials are important to understand
how CA3 neurons contribute to higher brain functions at cellular level. By using
confocally targeted patch-clamp recording techniques, we investigated the biophysical
properties of rat CA3 pyramidal neuron dendrites. We found two distinct dendritic
domains critical for action potential initiation and propagation: In the proximal
domain, action potentials initiated in the axon backpropagate actively with large
amplitude and fast time course. In the distal domain, Na+-channel mediated dendritic
spikes are efficiently evoked by local dendritic depolarization or waveforms mimicking
synaptic events. These findings can be explained by a high Na+-to-K+ conductance
density ratio of CA3 pyramidal neuron dendrites. The results challenge the prevailing
view that proximal mossy fiber inputs activate CA3 pyramidal neurons more efficiently
than distal perforant inputs by showing that the distal synapses trigger a different
form of activity represented by dendritic spikes. The high probability of dendritic
spike initiation in the distal area may enhance the computational power of CA3
pyramidal neurons in the hippocampal network. '

text: Visualizing and analyzing shape changes at various scales, ranging from single
molecules to whole organisms, are essential for understanding complex morphogenetic
processes, such as early embryonic development. Embryo morphogenesis relies on
the interplay between different tissues, the properties of which are again determined
by the interaction between their constituent cells. Cell interactions, on the
other hand, are controlled by various molecules, such as signaling and adhesion
molecules, which in order to exert their functions need to be spatiotemporally
organized within and between the interacting cells. In this review, we will focus
on the role of cell adhesion functioning at different scales to organize cell,
tissue and embryo morphogenesis. We will specifically ask how the subcellular
distribution of adhesion molecules controls the formation of cell-cell contacts,
how cell-cell contacts determine tissue shape, and how tissue interactions regulate
embryo morphogenesis.

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: 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: We introduce the idea of using an explicit triangle mesh to track the air/fluid
interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial
surface mesh is created, this mesh is carried forward in time using nearby particle
velocities to advect the mesh vertices. The mesh connectivity remains mostly unchanged
across time-steps; it is only modified locally for topology change events or for
the improvement of triangle quality. In order to ensure that the surface mesh
does not diverge from the underlying particle simulation, we periodically project
the mesh surface onto an implicit surface defined by the physics simulation. The
mesh surface gives us several advantages over previous SPH surface tracking techniques.
We demonstrate a new method for surface tension calculations that clearly outperforms
the state of the art in SPH surface tension for computer graphics. We also demonstrate
a method for tracking detailed surface information (like colors) that is less
susceptible to numerical diffusion than competing techniques. Finally, our temporally-coherent
surface mesh allows us to simulate high-resolution surface wave dynamics without
being limited by the particle resolution of the SPH simulation.

text: "When searching for characteristic subpatterns in potentially noisy graph
data, it appears self-evident that having multiple observations would be better
than having just one. However, it turns out that the inconsistencies introduced
when different graph instances have different edge sets pose a serious challenge.
In this work we address this challenge for the problem of finding maximum weighted
cliques.\r\n We introduce the concept of most persistent soft-clique. This
is subset of vertices, that 1) is almost fully or at least densely connected,
2) occurs in all or almost all graph instances, and 3) has the maximum weight.
We present a measure of clique-ness, that essentially counts the number of edge
missing to make a subset of vertices into a clique. With this measure, we show
that the problem of finding the most persistent soft-clique problem can be cast
either as: a) a max-min two person game optimization problem, or b) a min-min
soft margin optimization problem. Both formulations lead to the same solution
when using a partial Lagrangian method to solve the optimization problems. By
experiments on synthetic data and on real social network data, we show that the
proposed method is able to reliably find soft cliques in graph data, even if that
is distorted by random noise or unreliable observations."

text: Generalized van der Corput sequences are onedimensional, infinite sequences
in the unit interval. They are generated from permutations in integer base b and
are the building blocks of the multi-dimensional Halton sequences. Motivated by
recent progress of Atanassov on the uniform distribution behavior of Halton sequences,
we study, among others, permutations of the form P(i) = ai (mod b) for coprime
integers a and b. We show that multipliers a that either divide b - 1 or b + 1
generate van der Corput sequences with weak distribution properties. We give explicit
lower bounds for the asymptotic distribution behavior of these sequences and relate
them to sequences generated from the identity permutation in smaller bases, which
are, due to Faure, the weakest distributed generalized van der Corput sequences.
