text: The scale invariance of natural images suggests an analogy to the statistical
mechanics of physical systems at a critical point. Here we examine the distribution
of pixels in small image patches and show how to construct the corresponding thermodynamics.
We find evidence for criticality in a diverging specific heat, which corresponds
to large fluctuations in how "surprising" we find individual images,
and in the quantitative form of the entropy vs energy. We identify special image
configurations as local energy minima and show that average patches within each
basin are interpretable as lines and edges in all orientations.

text: "Oriented mitosis is essential during tissue morphogenesis. The Wnt/planar
cell polarity (Wnt/PCP) pathway orients mitosis in a number of developmental systems,
including dorsal epiblast cell divisions along the animal-vegetal (A-V) axis during
zebrafish gastrulation. How Wnt signalling orients the mitotic plane is, however,
unknown. Here we show that, in dorsal epiblast cells, anthrax toxin receptor 2a
(Antxr2a) accumulates in a polarized cortical cap, which is aligned with the embryonic
A-V axis and forecasts the division plane. Filamentous actin (F-actin) also forms
an A-V polarized cap, which depends on Wnt/PCP and its effectors RhoA and Rock2.
Antxr2a is recruited to the cap by interacting with actin. Antxr2a also interacts
with RhoA and together they activate the diaphanous-related formin zDia2. Mechanistically,
Antxr2a functions as a Wnt-dependent polarized determinant, which, through the
action of RhoA and zDia2, exerts torque on the spindle to align it with the A-V
axis.\r\n"

text: The distribution of the phytohormone auxin regulates many aspects of plant
development including growth response to gravity. Gravitropic root curvature involves
coordinated and asymmetric cell elongation between the lower and upper side of
the root, mediated by differential cellular auxin levels. The asymmetry in the
auxin distribution is established and maintained by a spatio-temporal regulation
of the PIN-FORMED (PIN) auxin transporter activity. We provide novel insights
into the complex regulation of PIN abundance and activity during root gravitropism.
We show that PIN2 turnover is differentially regulated on the upper and lower
side of gravistimulated roots by distinct but partially overlapping auxin feedback
mechanisms. In addition to regulating transcription and clathrin-mediated internalization,
auxin also controls PIN abundance at the plasma membrane by promoting their vacuolar
targeting and degradation. This effect of elevated auxin levels requires the activity
of SKP-Cullin-F-box TIR1/AFB (SCF TIR1/AFB)-dependent pathway. Importantly, also
suboptimal auxin levels mediate PIN degradation utilizing the same signalling
pathway. These feedback mechanisms are functionally important during gravitropic
response and ensure fine-tuning of auxin fluxes for maintaining as well as terminating
asymmetric growth.

text: Cell polarisation in development is a common and fundamental process underlying
embryo patterning and morphogenesis, and has been extensively studied over the
past years. Our current knowledge of cell polarisation in development is predominantly
based on studies that have analysed polarisation of single cells, such as eggs,
or cellular aggregates with a stable polarising interface, such as cultured epithelial
cells (St Johnston and Ahringer, 2010). However, in embryonic development, particularly
of vertebrates, cell polarisation processes often encompass large numbers of cells
that are placed within moving and proliferating tissues, and undergo mesenchymal-to-epithelial
transitions with a highly complex spatiotemporal choreography. How such intricate
cell polarisation processes in embryonic development are achieved has only started
to be analysed. By using live imaging of neurulation in the transparent zebrafish
embryo, Buckley et al (2012) now describe a novel polarisation strategy by which
cells assemble an apical domain in the part of their cell body that intersects
with the midline of the forming neural rod. This mechanism, along with the previously
described mirror-symmetric divisions (Tawk et al, 2007), is thought to trigger
formation of both neural rod midline and lumen.

text: To fight infectious diseases, host immune defenses are employed at multiple
levels. Sanitary behavior, such as pathogen avoidance and removal, acts as a first
line of defense 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 toward pathogen-exposed group members [2].
One of the most common behaviors 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; 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
behavior extends the current understanding of grooming and the establishment of
social immunity in insect societies.

text: In this paper, we present the first output-sensitive algorithm to compute
the persistence diagram of a filtered simplicial complex. For any Γ > 0, it
returns only those homology classes with persistence at least Γ. Instead of the
classical reduction via column operations, our algorithm performs rank computations
on submatrices of the boundary matrix. For an arbitrary constant δ ∈ (0, 1), the
running time is O (C (1 - δ) Γ R d (n) log n), where C (1 - δ) Γ is the number
of homology classes with persistence at least (1 - δ) Γ, n is the total number
of simplices in the complex, d its dimension, and R d (n) is the complexity of
computing the rank of an n × n matrix with O (d n) nonzero entries. Depending
on the choice of the rank algorithm, this yields a deterministic O (C (1 - δ)
Γ n 2.376) algorithm, an O (C (1 - δ) Γ n 2.28) Las-Vegas algorithm, or an O (C
(1 - δ) Γ n 2 + ε{lunate}) Monte-Carlo algorithm for an arbitrary ε{lunate} >
0. The space complexity of the Monte-Carlo version is bounded by O (d n) = O (n
log n).

text: "A chain rule for an entropy notion H(.) states that the entropy H(X) of a
variable X decreases by at most l if conditioned on an l-bit string A, i.e., H(X|A)>=
H(X)-l. More generally, it satisfies a chain rule for conditional entropy if H(X|Y,A)>=
H(X|Y)-l.\r\n\r\nAll natural information theoretic entropy notions we are aware
of (like Shannon or min-entropy) satisfy some kind of chain rule for conditional
entropy. Moreover, many computational entropy notions (like Yao entropy, unpredictability
entropy and several variants of HILL entropy) satisfy the chain rule for conditional
entropy, though here not only the quantity decreases by l, but also the quality
of the entropy decreases exponentially in l. However, for \r\nthe standard notion
of conditional HILL entropy (the computational equivalent of min-entropy) the
existence of such a rule was unknown so far.\r\n\r\nIn this paper, we prove that
for conditional HILL entropy no meaningful chain rule exists, assuming the existence
of one-way permutations: there exist distributions X,Y,A, where A is a distribution
over a single bit, but $H(X|Y)>>H(X|Y,A)$, even if we simultaneously allow
for a massive degradation in the quality of the entropy.\r\n\r\nThe idea underlying
our construction is based on a surprising connection between the chain rule for
HILL entropy and deniable encryption. "

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: 'Many visual datasets are traditionally used to analyze the performance of
different learning techniques. The evaluation is usually done within each dataset,
therefore it is questionable if such results are a reliable indicator of true
generalization ability. We propose here an algorithm to exploit the existing data
resources when learning on a new multiclass problem. Our main idea is to identify
an image representation that decomposes orthogonally into two subspaces: a part
specific to each dataset, and a part generic to, and therefore shared between,
all the considered source sets. This allows us to use the generic representation
as un-biased reference knowledge for a novel classification task. By casting the
method in the multi-view setting, we also make it possible to use different features
for different databases. We call the algorithm MUST, Multitask Unaligned Shared
knowledge Transfer. Through extensive experiments on five public datasets, we
show that MUST consistently improves the cross-datasets generalization performance.'

text: Multithreaded programs coordinate their interaction through synchronization
primitives like mutexes and semaphores, which are managed by an OS-provided resource
manager. We propose algorithms for the automatic construction of code-aware resource
managers for multithreaded embedded applications. Such managers use knowledge
about the structure and resource usage (mutex and semaphore usage) of the threads
to guarantee deadlock freedom and progress while managing resources in an efficient
way. Our algorithms compute managers as winning strategies in certain infinite
games, and produce a compact code description of these strategies. We have implemented
the algorithms in the tool Cynthesis. Given a multithreaded program in C, the
tool produces C code implementing a code-aware resource manager. We show in experiments
that Cynthesis produces compact resource managers within a few minutes on a set
of embedded benchmarks with up to 6 threads. © 2012 Springer Science+Business

text: Cells in a developing embryo have no direct way of "measuring" their
physical position. Through a variety of processes, however, the expression levels
of multiple genes come to be correlated with position, and these expression levels
thus form a code for "positional information." We show how to measure
this information, in bits, using the gap genes in the Drosophila embryo as an
example. Individual genes carry nearly two bits of information, twice as much
as expected if the expression patterns consisted only of on/off domains separated
by sharp boundaries. Taken together, four gap genes carry enough information to
define a cell's location with an error bar of ~1% along the anterior-posterior
axis of the embryo. This precision is nearly enough for each cell to have a unique
identity, which is the maximum information the system can use, and is nearly constant
along the length of the embryo. We argue that this constancy is a signature of
optimality in the transmission of information from primary morphogen inputs to
the output of the gap gene network.

text: Understanding the relative importance of heterosis and outbreeding depression
over multiple generations is a key question in evolutionary biology and is essential
for identifying appropriate genetic sources for population and ecosystem restoration.
Here we use 2455 experimental crosses between 12 population pairs of the rare
perennial plant Rutidosis leptorrhynchoides (Asteraceae) to investigate the multi-generational
(F1, F2, F3) fitness outcomes of inter-population hybridization. We detected no
evidence of outbreeding depression, with inter-population hybrids and backcrosses
showing either similar fitness or significant heterosis for fitness components
across the three generations. Variation in heterosis among population pairs was
best explained by characteristics of the foreign source or home population, and
was greatest when the source population was large, with high genetic diversity
and low inbreeding, and the home population was small and inbred. Our results
indicate that the primary consideration for maximizing progeny fitness following
population augmentation or restoration is the use of seed from large, genetically
diverse populations.

text: 'Maternal exposure to infection occurring mid-gestation produces a three-fold
increase in the risk of schizophrenia in the offspring. The critical initiating
factor appears to be the maternal immune activation (MIA) that follows infection.
This process can be induced in rodents by exposure of pregnant dams to the viral
mimic Poly I:C, which triggers an immune response that results in structural,
functional, behavioral, and electrophysiological phenotypes in the adult offspring
that model those seen in schizophrenia. We used this model to explore the role
of synchronization in brain neural networks, a process thought to be dysfunctional
in schizophrenia and previously associated with positive, negative, and cognitive
symptoms of schizophrenia. Exposure of pregnant dams to Poly I:C on GD15 produced
an impairment in long-range neural synchrony in adult offspring between two regions
implicated in schizophrenia pathology; the hippocampus and the medial prefrontal
cortex (mPFC). This reduction in synchrony was ameliorated by acute doses of the
antipsychotic clozapine. MIA animals have previously been shown to have impaired
pre-pulse inhibition (PPI), a gold-standard measure of schizophrenia-like deficits
in animal models. Our data showed that deficits in synchrony were positively correlated
with the impairments in PPI. Subsequent analysis of LFP activity during the PPI
response also showed that reduced coupling between the mPFC and the hippocampus
following processing of the pre-pulse was associated with reduced PPI. The ability
of the MIA intervention to model neurodevelopmental aspects of schizophrenia pathology
provides a useful platform from which to investigate the ontogeny of aberrant
synchronous processes. Further, the way in which the model expresses translatable
deficits such as aberrant synchrony and reduced PPI will allow researchers to
explore novel intervention strategies targeted to these changes. '

text: Exposure of an isogenic bacterial population to a cidal antibiotic typically
fails to eliminate a small fraction of refractory cells. Historically, fractional
killing has been attributed to infrequently dividing or nondividing "persisters."
Using microfluidic cultures and time-lapse microscopy, we found that Mycobacterium
smegmatis persists by dividing in the presence of the drug isoniazid (INH). Although
persistence in these studies was characterized by stable numbers of cells, this
apparent stability was actually a dynamic state of balanced division and death.
Single cells expressed catalase-peroxidase (KatG), which activates INH, in stochastic
pulses that were negatively correlated with cell survival. These behaviors may
reflect epigenetic effects, because KatG pulsing and death were correlated between
sibling cells. Selection of lineages characterized by infrequent KatG pulsing
could allow nonresponsive adaptation during prolonged drug exposure.

text: 'Background: Reassortment between the RNA segments encoding haemagglutinin
(HA) and neuraminidase (NA), the major antigenic influenza proteins, produces
viruses with novel HA and NA subtype combinations and has preceded the emergence
of pandemic strains. It has been suggested that productive viral infection requires
a balance in the level of functional activity of HA and NA, arising from their
closely interacting roles in the viral life cycle, and that this functional balance
could be mediated by genetic changes in the HA and NA. Here, we investigate how
the selective pressure varies for H7 avian influenza HA on different NA subtype
backgrounds. Results: By extending Bayesian stochastic mutational mapping methods
to calculate the ratio of the rate of non-synonymous change to the rate of synonymous
change (d N/d S), we found the average d N/d S across the avian influenza H7 HA1
region to be significantly greater on an N2 NA subtype background than on an N1,
N3 or N7 background. Observed differences in evolutionary rates of H7 HA on different
NA subtype backgrounds could not be attributed to underlying differences between
avian host species or virus pathogenicity. Examination of d N/d S values for each
subtype on a site-by-site basis indicated that the elevated d N/d S on the N2
NA background was a result of increased selection, rather than a relaxation of
selective constraint. Conclusions: Our results are consistent with the hypothesis
that reassortment exposes influenza HA to significant changes in selective pressure
through genetic interactions with NA. Such epistatic effects might be explicitly
accounted for in future models of influenza evolution.'

text: 'All known species of extant tapirs are allopatric: 1 in southeastern Asia
and 3 in Central and South America. The fossil record for tapirs, however, is
much wider in geographical range, including Europe, Asia, and North and South
America, going back to the late Oligocene, making the present distribution a relict
of the original one. We here describe a new species of living Tapirus from the
Amazon rain forest, the 1st since T. bairdii Gill, 1865, and the 1st new Perissodactyla
in more than 100 years, from both morphological and molecular characters. It is
shorter in stature than T. terrestris (Linnaeus, 1758) and has distinctive skull
morphology, and it is basal to the clade formed by T. terrestris and T. pinchaque
(Roulin, 1829). This highlights the unrecognized biodiversity in western Amazonia,
where the biota faces increasing threats. Local peoples have long recognized our
new species, suggesting a key role for traditional knowledge in understanding
the biodiversity of the region.'

text: 'Blind signatures allow users to obtain signatures on messages hidden from
the signer; moreover, the signer cannot link the resulting message/signature pair
to the signing session. This paper presents blind signature schemes, in which
the number of interactions between the user and the signer is minimal and whose
blind signatures are short. Our schemes are defined over bilinear groups and are
proved secure in the common-reference-string model without random oracles and
under standard assumptions: CDH and the decision-linear assumption. (We also give
variants over asymmetric groups based on similar assumptions.) The blind signatures
are Waters signatures, which consist of 2 group elements. Moreover, we instantiate
partially blind signatures, where the message consists of a part hidden from the
signer and a commonly known public part, and schemes achieving perfect blindness.
We propose new variants of blind signatures, such as signer-friendly partially
blind signatures, where the public part can be chosen by the signer without prior
agreement, 3-party blind signatures, as well as blind signatures on multiple aggregated
messages provided by independent sources. We also extend Waters signatures to
non-binary alphabets by proving a new result on the underlying hash function. '

text: Alkyd resins are polyesters containing unsaturated fatty acids that are used
as binding agents in paints and coatings. Chemical drying of these polyesters
is based on heavy metal catalyzed cross-linking of the unsaturated fatty acid
moieties. Among the heavy-metal catalysts, cobalt complexes are the most effective,
yet they have been proven to be carcinogenic. Therefore, strategies to replace
the cobalt-based catalyst by environmentally friendlier and less toxic alternatives
are under development. Here, we demonstrate for the first time that a laccase-mediator
system can effectively replace the heavy-metal catalyst and cross-link alkyd resins.
Interestingly, the biocatalytic reaction does not only work in aqueous media,
but also in a solid film, where enzyme diffusion is limited. Within the catalytic
cycle, the mediator oxidizes the alkyd resin and is regenerated by the laccase,
which is uniformly distributed within the drying film as evidenced by confocal
laser scanning microscopy. During gradual build-up of molecular weight, there
is a concomitant decrease of the oxygen content in the film. A new optical sensor
to follow oxygen consumption during the cross-linking reaction was developed and
validated with state of the art techniques. A remarkable feature is the low sample
amount required, which allows faster screening of new catalysts.

text: Fertilization in flowering plants requires the temporal and spatial coordination
of many developmental processes, including pollen production, anther dehiscence,
ovule production, and pollen tube elongation. However, it remains elusive as to
how this coordination occurs during reproduction. Here, we present evidence that
endocytosis, involving heterotetrameric adaptor protein complex 2 (AP-2), plays
a crucial role in fertilization. An Arabidopsis thaliana mutant ap2m displays
multiple defects in pollen production and viability, as well as elongation of
staminal filaments and pollen tubes, all of which are pivotal processes needed
for fertilization. Of these abnormalities, the defects in elongation of staminal
filaments and pollen tubes were partially rescued by exogenous auxin. Moreover,
DR5rev:GFP (for green fluorescent protein) expression was greatly reduced in filaments
and anthers in ap2m mutant plants. At the cellular level, ap2m mutants displayed
defects in both endocytosis of N-(3-triethylammonium-propyl)-4- (4-diethylaminophenylhexatrienyl)
pyridinium dibromide, a lypophilic dye used as an endocytosis marker, and polar
localization of auxin-efflux carrier PIN FORMED2 (PIN2) in the stamen filaments.
Moreover, these defects were phenocopied by treatment with Tyrphostin A23, an
inhibitor of endocytosis. Based on these results, we propose that AP-2-dependent
endocytosis plays a crucial role in coordinating the multiple developmental aspects
of male reproductive organs by modulating cellular auxin level through the regulation
of the amount and polarity of PINs.
