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: "Efficient zero-knowledge proofs of knowledge (ZK-PoK) are basic building
blocks of many practical cryptographic applications such as identification schemes,
group signatures, and secure multiparty computation. Currently, first applications
that critically rely on ZK-PoKs are being deployed in the real world. The most
prominent example is Direct Anonymous Attestation (DAA), which was adopted by
the Trusted Computing Group (TCG) and implemented as one of the functionalities
of the cryptographic Trusted Platform Module (TPM) chip.\n\nImplementing systems
using ZK-PoK turns out to be challenging, since ZK-PoK are, loosely speaking,
significantly more complex than standard crypto primitives, such as encryption
and signature schemes. As a result, implementation cycles of ZK-PoK are time-consuming
and error-prone, in particular for developers with minor or no cryptographic skills.
\n\nIn this paper we report on our ongoing and future research vision with the
goal to bring ZK-PoK to practice by making them accessible to crypto and security
engineers. To this end we are developing compilers and related tools that support
and partially automate the design, implementation, verification and secure implementation
of ZK-PoK protocols."

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: We report a procedure to prepare highly monodisperse copper telluride nanocubes,
nanoplates, and nanorods. The procedure is based on the reaction of a copper salt
with trioctylphosphine telluride in the presence of lithium bis(trimethylsilyl)amide
and oleylamine. CuTe nanocrystals display a strong near-infrared optical absorption
associated with localized surface plasmon resonances. We exploit this plasmon
resonance for the design of surface-enhanced Raman scattering sensors for unconventional
optical probes. Furthermore, we also report here our preliminary analysis of the
use of CuTe nanocrystals as cytotoxic and photothermal agents.

text: Morphology is a key parameter in the design of novel nanocrystals and nanomaterials
with controlled functional properties. Here, we demonstrate the potential of foreign
metal ions to tune the morphology of colloidal semiconductor nanoparticles. We
illustrate the underlying mechanism by preparing copper selenide nanocubes in
the presence of Al ions. We further characterize the plasmonic properties of the
obtained nanocrystals and demonstrate their potential as a platform to produce
cubic nanoparticles with different composition by cation exchange. © 2013 American

text: The bottom-up assembly of nanocrystals provides access to a three-dimensional
composition control at the nanoscale not attainable by any other technology. In
particular, colloidal nanoheterostructures, with intrinsic multiphase organization,
are especially appealing building blocks for the bottom-up production of nanocomposites.
In the present work, we use PbTe-PbS as the model material system and thermoelectricity
as the paradigmatic application to investigate the potential of the bottom-up
assembly of core-shell nanoparticles to produce functional nanocomposites. With
this goal in mind, a rapid, high-yield and scalable colloidal synthetic route
to prepare grams of PbTe@PbS core-shell nanoparticles with unprecedented narrow
size distributions and exceptional composition control is detailed. PbTe@PbS nanoparticles
were used as building blocks for the bottom-up production of PbTe-PbS nanocomposites
with tuned composition. In such PbTe-PbS nanocomposites, synergistic nanocrystal
doping effects result in up to 10-fold higher electrical conductivities than in
pure PbTe and PbS nanomaterials. At the same time, the acoustic impedance mismatch
between PbTe and PbS phases and a partial phase alloying provide PbTe-PbS nanocomposites
with strongly reduced thermal conductivities. As a result, record thermoelectric
figures of merit (ZT) of ∼1.1 were obtained from undoped PbTe and PbS phases at
710 K. These high ZT values prove the potential of the proposed processes to produce
efficient functional nanomaterials with programmable properties. © 2013 American

text: Copper-based selenides are attracting increasing interest due to their outstanding
optoelectronic and thermoelectric properties. Herein a novel colloidal synthetic
route to prepare Cu2SnSe3 nanocrystals with controlled size, shape and composition
is presented. The high yield of the developed procedure allowed its up-scaling
to the production of grams of colloidal Cu2SnSe3 nanocrystals. These nanocrystals
were used as building blocks for the production of Cu2SnSe3 bulk nanostructured
materials by spark plasma sintering. The thermoelectric properties of the prepared
nanocrystalline Cu2SnSe3 pellets were characterized in the temperature range from
300 to 720 K. The obtained results show the bottom-up production of nanocrystalline
materials from solution-processed nanocrystals to be a potentially advantageous
alternative to conventional methods of production of efficient thermoelectric
materials.

text: 'A multistrategy approach to overcome the main challenges of nanoparticle-based
solution-processed Cu2ZnSnSe4 thin film solar cells is presented. We developed
an efficient ligand exchange strategy, using an antimony salt, to displace organic
ligands from the surface of Cu 2ZnSnS4 nanoparticles. An automated pulsed spray-deposition
system was used to deposit the nanoparticles into homogeneous and crack-free films
with controlled thickness. After annealing the film in a Se-rich atmosphere, carbon-free
and crystalline Cu2ZnSnSe4 absorber layers were obtained. Not only was crystallization
promoted by the complete removal of organics, but also Sb itself played a critical
role. The Sb-assisted crystal growth is associated with the formation of a Sb-based
compound at the grain boundaries, which locally reduces the melting point, thus
promoting the film diffusion-limited crystallization. '

text: The presence of organic ligands on the surface of colloidal nanoparticles
strongly limits their performance in technological applications where charge carrier
transfer/transport plays an important role. We use metal salts, matched with the
nanoparticle composition, to eliminate the surface organic ligands without introducing
extrinsic impurities in the final nanomaterial. The potential of the simple, general
and scalable processes presented here is demonstrated by characterizing the thermoelectric
properties of nanostructured Ag2Te produced by the bottom up assembly of Ag2Te
nanocrystals. A 6-fold increase of the thermoelectric figure of merit of Ag2Te
was obtained when organic ligands were displaced by AgNO3. The same procedure
can enhance the performance of nanocrystals and nanocrystal-based devices in a
broad range of applications, from photovoltaics and thermoelectrics to catalysis.

text: We report a procedure to prepare highly monodisperse copper telluride nanocubes,
nanoplates, and nanorods. The procedure is based on the reaction of a copper salt
with trioctylphosphine telluride in the presence of lithium bis(trimethylsilyl)amide
and oleylamine. CuTe nanocrystals display a strong near-infrared optical absorption
associated with localized surface plasmon resonances. We exploit this plasmon
resonance for the design of surface-enhanced Raman scattering sensors for unconventional
optical probes. Furthermore, we also report here our preliminary analysis of the
use of CuTe nanocrystals as cytotoxic and photothermal agents.

text: The compositional versatility of I2–II–IV–VI4 tetrahedrally-coordinated compounds
allows for accommodating their functional properties to numerous technological
applications. Among them, Cu2ZnSnSe4 is an emerging photovoltaic material and
Cu2CdSnSe4 displays excellent thermoelectric properties. The third compound of
this family, Cu2HgSnSe4, remains relatively unexplored. Herein, a synthetic route
to produce Cu2HgSnSe4 nanoparticles with narrow size distribution and controlled
composition is presented. Cu2HgSnSe4 nanoparticles were subsequently used as building
blocks to produce bulk nanocrystalline materials, whose thermoelectric properties
were analyzed. A very preliminary adjustment of the material composition yielded
Seebeck coefficients up to 160 μV K−1, electrical conductivities close to 104
S m−1 and thermal conductivities down to 0.5 W m−1 K−1.

text: Until recently, to prepare nanocrystals of a new material, scientists searched
their shelves for the appropriate molecular precursors, surfactants, and solvents.
They then optimized the reaction conditions for the atoms to self-assemble into
monodisperse nanocrystals (1). This approach is being replaced by a simpler strategy,
in which preformed nanocrystals serve as templates to produce nanoparticles with
a different composition through chemical transformation. On page 964 of this issue,
Oh et al. (2) report a powerful mechanism that allows the composition of oxide
nanoparticles to be transformed in solution and at low temperatures.

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. '
