text: Dispersal is crucial for gene flow and often determines the long-term stability
of meta-populations, particularly in rare species with specialized life cycles.
Such species are often foci of conservation efforts because they suffer disproportionally
from degradation and fragmentation of their habitat. However, detailed knowledge
of effective gene flow through dispersal is often missing, so that conservation
strategies have to be based on mark-recapture observations that are suspected
to be poor predictors of long-distance dispersal. These constraints have been
especially severe in the study of butterfly populations, where microsatellite
markers have been difficult to develop. We used eight microsatellite markers to
analyse genetic population structure of the Large Blue butterfly Maculinea arion
in Sweden. During recent decades, this species has become an icon of insect conservation
after massive decline throughout Europe and extinction in Britain followed by
reintroduction of a seed population from the Swedish island of Öland. We find
that populations are highly structured genetically, but that gene flow occurs
over distances 15 times longer than the maximum distance recorded from mark-recapture
studies, which can only be explained by maximum dispersal distances at least twice
as large as previously accepted. However, we also find evidence that gaps between
sites with suitable habitat exceeding ∼ 20 km induce genetic erosion that can
be detected from bottleneck analyses. Although further work is needed, our results
suggest that M. arion can maintain fully functional metapopulations when they
consist of optimal habitat patches that are no further apart than ∼10 km.

text: We describe here the development and characterization of a conditionally inducible
mouse model expressing Lifeact-GFP, a peptide that reports the dynamics of filamentous
actin. We have used this model to study platelets, megakaryocytes and melanoblasts
and we provide evidence that Lifeact-GFP is a useful reporter in these cell types
ex vivo. In the case of platelets and megakaryocytes, these cells are not transfectable
by traditional methods, so conditional activation of Lifeact allows the study
of actin dynamics in these cells live. We studied melanoblasts in native skin
explants from embryos, allowing the visualization of live actin dynamics during
cytokinesis and migration. Our study revealed that melanoblasts lacking the small
GTPase Rac1 show a delay in the formation of new pseudopodia following cytokinesis
that accounts for the previously reported cytokinesis delay in these cells. Thus,
through use of this mouse model, we were able to gain insights into the actin
dynamics of cells that could only previously be studied using fixed specimens
or following isolation from their native tissue environment.

text: We describe RTblob, a high speed vision system that detects objects in cluttered
scenes based on their color and shape at a speed of over 800 frames/s. Because
the system is available as open-source software and relies only on off-the-shelf
PC hardware components, it can provide the basis for multiple application scenarios.
As an illustrative example, we show how RTblob can be used in a robotic table
tennis scenario to estimate ball trajectories through 3D space simultaneously
from four cameras images at a speed of 200 Hz.

text: The Brazilian Merganser is a very rare and threatened species that nowadays
inhabits only a few protected areas and their surroundings in the Brazilian territory.
In order to estimate the remaining genetic diversity and population structure
in this species, two mitochondrial genes were sequenced in 39 individuals belonging
to two populations and in one individual collected in Argentina in 1950. We found
a highly significant divergence between two major remaining populations of Mergus
octosetaceus, which suggests a historical population structure in this species.
Furthermore, two deeply divergent lineages were found in a single location, which
could due to current or historical secondary contact. Based on the available genetic
data, we point out future directions which would contribute to design strategies
for conservation and management of this threatened species.

text: How cells orchestrate their behavior during collective migration is a long-standing
question. Using magnetic tweezers to apply mechanical stimuli to Xenopus mesendoderm
cells, Weber etal. (2012) now reveal, in this issue of Developmental Cell, a cadherin-mediated
mechanosensitive response that promotes cell polarization and movement persistence
during the collective mesendoderm migration in gastrulation.

text: Living cells must control the reading out or "expression" of information
encoded in their genomes, and this regulation often is mediated by transcription
factors--proteins that bind to DNA and either enhance or repress the expression
of nearby genes. But the expression of transcription factor proteins is itself
regulated, and many transcription factors regulate their own expression in addition
to responding to other input signals. Here we analyze the simplest of such self-regulatory
circuits, asking how parameters can be chosen to optimize information transmission
from inputs to outputs in the steady state. Some nonzero level of self-regulation
is almost always optimal, with self-activation dominant when transcription factor
concentrations are low and self-repression dominant when concentrations are high.
In steady state the optimal self-activation is never strong enough to induce bistability,
although there is a limit in which the optimal parameters are very close to the
critical point.

text: Consider a convex relaxation f̂ of a pseudo-Boolean function f. We say that
the relaxation is totally half-integral if f̂(x) is a polyhedral function with
half-integral extreme points x, and this property is preserved after adding an
arbitrary combination of constraints of the form x i=x j, x i=1-x j, and x i=γ
where γ∈{0,1,1/2} is a constant. A well-known example is the roof duality relaxation
for quadratic pseudo-Boolean functions f. We argue that total half-integrality
is a natural requirement for generalizations of roof duality to arbitrary pseudo-Boolean
functions. Our contributions are as follows. First, we provide a complete characterization
of totally half-integral relaxations f̂ by establishing a one-to-one correspondence
with bisubmodular functions. Second, we give a new characterization of bisubmodular
functions. Finally, we show some relationships between general totally half-integral
relaxations and relaxations based on the roof duality. On the conceptual level,
our results show that bisubmodular functions provide a natural generalization
of the roof duality approach to higher-order terms. This can be viewed as a non-submodular
analogue of the fact that submodular functions generalize the s-t minimum cut
problem with non-negative weights to higher-order terms.

text: The problem of the origin of metazoa is becoming more urgent in the context
of astrobiology. By now it is clear that clues to the understanding of this crucial
transition in the evolution of life can arise in a fourth pathway besides the
three possibilities in the quest for simplicity outlined by Bonner in his classical
book. In other words, solar system exploration seems to be one way in the long-term
to elucidate the simplicity of evolutionary development. We place these ideas
in the context of different inheritance systems, namely the genotypic and phenotypic
replicators with limited or unlimited heredity, and ask which of these can support
multicellular development, and to which degree of complexity. However, the quest
for evidence on the evolution of biotas from planets around other stars does not
seem to be feasible with present technology with direct visualization of living
organisms on exoplanets. But this may be attempted on the Galilean moons of Jupiter
where there is a possibility of detecting reliable biomarkers in the next decade
with the Europa Jupiter System Mission, in view of recent progress by landing
micropenetrators on planetary, or satellite surfaces. Mars is a second possibility
in the inner Solar System, in spite of the multiple difficulties faced by the
fleet of past, present and future missions. We discuss a series of preliminary
ideas for elucidating the origin of metazoan analogues with available instrumentation
in potential payloads of feasible space missions to the Galilean moons.

text: "We show a hardness-preserving construction of a PRF from any length doubling
PRG which improves upon known constructions whenever we can put a non-trivial
upper bound q on the number of queries to the PRF. Our construction requires only
O(logq) invocations to the underlying PRG with each query. In comparison, the
number of invocations by the best previous hardness-preserving construction (GGM
using Levin's trick) is logarithmic in the hardness of the PRG. For example, starting
from an exponentially secure PRG {0,1} n → {0,1} 2n, we get a PRF which is exponentially
secure if queried at most q = exp(√n)times and where each invocation of the PRF
requires Θ(√n) queries to the underlying PRG. This is much less than the Θ(n)
required by known constructions. \r\n"

text: A boundary element model of a tunnel running through horizontally layered
soil with anisotropic material properties is presented. Since there is no analytical
fundamental solution for wave propagation inside a layered orthotropic medium
in 3D, the fundamental displacements and stresses have to be calculated numerically.
In our model this is done in the Fourier domain with respect to space and time.
The assumption of a straight tunnel with infinite extension in the x direction
makes it possible to decouple the system for every wave number kx, leading to
a 2.5D-problem, which is suited for parallel computation. The special form of
the fundamental solution, resulting from our Fourier ansatz, and the fact, that
the calculation of the boundary integral equation is performed in the Fourier
domain, enhances the stability and efficiency of the numerical calculations.

text: "Viral manipulation of transduction pathways associated with key cellular
functions such as survival, response to microbial infection, and cytoskeleton
reorganization can provide the supportive milieu for a productive infection. Here,
we demonstrate that vaccinia virus (VACV) infection leads to activation of the
stress-activated protein kinase (SAPK)/extracellular signal-regulated kinase (ERK)
4/7 (MKK4/7)-c-Jun N-terminal protein kinase 1/2 (JNK1/2) pathway; further, the
stimulation of this pathway requires postpenetration, prereplicative events in
the viral replication cycle. Although the formation of intracellular mature virus
(IMV) was not affected in MKK4/7- or JNK1/2-knockout (KO) cells, we did note an
accentuated deregulation of microtubule and actin network organization in infected
JNK1/2-KO cells. This was followed by deregulated viral trafficking to the periphery
and enhanced enveloped particle release. Furthermore, VACV infection induced alterations
in the cell contractility and morphology, and cell migration was reduced in the
JNK-KO cells. In addition, phosphorylation of proteins implicated with early cell
contractility and cell migration, such as microtubule-associated protein 1B and
paxillin, respectively, was not detected in the VACV-infected KO cells. In sum,
our findings uncover a regulatory role played by the MKK4/7-JNK1/2 pathway in
cytoskeleton reorganization during VACV infection.\r\n"

text: The theory of persistent homology opens up the possibility to reason about
topological features of a space or a function quantitatively and in combinatorial
terms. We refer to this new angle at a classical subject within algebraic topology
as a point calculus, which we present for the family of interlevel sets of a real-valued
function. Our account of the subject is expository, devoid of proofs, and written
for non-experts in algebraic topology.

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.

text: A high-yield and upscalable colloidal synthesis route for the production of
quaternary I 2-II-IV-VI 4 nanocrystals, particularly stannite Cu 2+xCd 1-xSnSe
4, with narrow size distribution and precisely controlled composition is presented.
It is also shown here how the diversity of valences in the constituent elements
allows an effective control of their electrical conductivity through the adjustment
of the cation ratios. At the same time, while the crystallographic complexity
of quaternary chalcogenides is associated with intrinsically low thermal conductivities,
the reduction of the lattice dimensions to the nanoscale further reduces the materials
thermal conductivity. In the specific case of the stannite crystal structure,
a convenient slab distribution of the valence band maximum states permits a partial
decoupling of the p-type electrical conductivity from both the Seebeck coefficient
and the thermal conductivity. Combining these features, we demonstrate how an
initial optimization of the nanocrystals Cd/Cu ratio allowed us to obtain low-temperature
solution-processed materials with ZT values up to 0.71 at 685 K.

text: 'A procedure for the continuous production of Cu 2ZnSnS 4 (CZTS) nanoparticles
with controlled composition is presented. CZTS nanoparticles were prepared through
the reaction of the metals'' amino complexes with elemental sulfur in a continuous-flow
reactor at moderate temperatures (300-330 °C). High-resolution transmission electron
microscopy and X-ray diffraction analysis showed the nanocrystals to have a crystallographic
structure compatible with that of the kesterite. Chemical characterization of
the materials showed the presence of the four elements in each individual nanocrystal.
Composition control was achieved by adjusting the solution flow rate through the
reactor and the proper choice of the nominal precursor concentration within the
flowing solution. Single-particle analysis revealed a composition distribution
within each sample, which was optimized at the highest synthesis temperatures
used. '

text: 'Nanocomposites are highly promising materials to enhance the efficiency of
current thermoelectric devices. A straightforward and at the same time highly
versatile and controllable approach to produce nanocomposites is the assembly
of solution-processed nanocrystal building blocks. The convenience of this bottom-up
approach to produce nanocomposites with homogeneous phase distributions and adjustable
composition is demonstrated here by blending Ag2Te and PbTe colloidal nanocrystals
to form Ag2Te–PbTe bulk nanocomposites. The thermoelectric properties of these
nanocomposites are analyzed in the temperature range from 300 to 700 K. The evolution
of their electrical conductivity and Seebeck coefficient is discussed in terms
of the blend composition and the characteristics of the constituent materials. '

text: 'A synthetic route for producing Cu 2ZnGeSe 4 nanocrystals with narrow size
distributions and controlled composition is presented. These nanocrystals were
used to produce densely packed nanomaterials by hot-pressing. From the characterization
of the thermoelectric properties of these nanomaterials, Cu 2ZnGeSe 4 is demonstrated
to show excellent thermoelectric properties. A very preliminary adjustment of
the nanocrystal composition has already resulted in a figure of merit of up to
0.55 at 450°C. '

text: Hierarchical Timing Language (HTL) is a coordination language for distributed,
hard real-time applications. HTL is a hierarchical extension of Giotto and, like
its predecessor, based on the logical execution time (LET) paradigm of real-time
programming. Giotto is compiled into code for a virtual machine, called the EmbeddedMachine
(or E machine). If HTL is targeted to the E machine, then the hierarchicalprogram
structure needs to be flattened; the flattening makes separatecompilation difficult,
and may result in E machinecode of exponential size. In this paper, we propose
a generalization of the E machine, which supports a hierarchicalprogram structure
at runtime through real-time trigger mechanisms that are arranged in a tree. We
present the generalized E machine, and a modular compiler for HTL that generates
code of linear size. The compiler may generate code for any part of a given HTL
program separately in any order.

text: 'Energy parity games are infinite two-player turn-based games played on weighted
graphs. The objective of the game combines a (qualitative) parity condition with
the (quantitative) requirement that the sum of the weights (i.e., the level of
energy in the game) must remain positive. Beside their own interest in the design
and synthesis of resource-constrained omega-regular specifications, energy parity
games provide one of the simplest model of games with combined qualitative and
quantitative objectives. Our main results are as follows: (a) exponential memory
is sufficient and may be necessary for winning strategies in energy parity games;
(b) the problem of deciding the winner in energy parity games can be solved in
NP ∩ coNP; and (c) we give an algorithm to solve energy parity by reduction to
energy games. We also show that the problem of deciding the winner in energy parity
games is logspace-equivalent to the problem of deciding the winner in mean-payoff
parity games, which can thus be solved in NP ∩ coNP. As a consequence we also
obtain a conceptually simple algorithm to solve mean-payoff parity games.'

text: For programs whose data variables range over Boolean or finite domains, program
verification is decidable, and this forms the basis of recent tools for software
model checking. In this article, we consider algorithmic verification of programs
that use Boolean variables, and in addition, access a single read-only array whose
length is potentially unbounded, and whose elements range over an unbounded data
domain. We show that the reachability problem, while undecidable in general, is
(1) PSPACE-complete for programs in which the array-accessing for-loops are not
nested, (2) decidable for a restricted class of programs with doubly nested loops.
The second result establishes connections to automata and logics defining languages
over data words.
