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.

text: 'Background: Characterizing root system architecture (RSA) is essential to
understanding the development and function of vascular plants. Identifying RSA-associated
genes also represents an underexplored opportunity for crop improvement. Software
tools are needed to accelerate the pace at which quantitative traits of RSA are
estimated from images of root networks.Results: We have developed GiA Roots (General
Image Analysis of Roots), a semi-automated software tool designed specifically
for the high-throughput analysis of root system images. GiA Roots includes user-assisted
algorithms to distinguish root from background and a fully automated pipeline
that extracts dozens of root system phenotypes. Quantitative information on each
phenotype, along with intermediate steps for full reproducibility, is returned
to the end-user for downstream analysis. GiA Roots has a GUI front end and a command-line
interface for interweaving the software into large-scale workflows. GiA Roots
can also be extended to estimate novel phenotypes specified by the end-user.Conclusions:
We demonstrate the use of GiA Roots on a set of 2393 images of rice roots representing
12 genotypes from the species Oryza sativa. We validate trait measurements against
prior analyses of this image set that demonstrated that RSA traits are likely
heritable and associated with genotypic differences. Moreover, we demonstrate
that GiA Roots is extensible and an end-user can add functionality so that GiA
Roots can estimate novel RSA traits. In summary, we show that the software can
function as an efficient tool as part of a workflow to move from large numbers
of root images to downstream analysis.'

text: 'The BCI competition IV stands in the tradition of prior BCI competitions
that aim to provide high quality neuroscientific data for open access to the scientific
community. As experienced already in prior competitions not only scientists from
the narrow field of BCI compete, but scholars with a broad variety of backgrounds
and nationalities. They include high specialists as well as students.The goals
of all BCI competitions have always been to challenge with respect to novel paradigms
and complex data. We report on the following challenges: (1) asynchronous data,
(2) synthetic, (3) multi-class continuous data, (4) sessionto-session transfer,
(5) directionally modulated MEG, (6) finger movements recorded by ECoG. As after
past competitions, our hope is that winning entries may enhance the analysis methods
of future BCIs.'

text: An automaton with advice is a finite state automaton which has access to an
additional fixed infinite string called an advice tape. We refine the Myhill-Nerode
theorem to characterize the languages of finite strings that are accepted by automata
with advice. We do the same for tree automata with advice.

text: Understanding patterns and correlates of local adaptation in heterogeneous
landscapes can provide important information in the selection of appropriate seed
sources for restoration. We assessed the extent of local adaptation of fitness
components in 12 population pairs of the perennial herb Rutidosis leptorrhynchoides
(Asteraceae) and examined whether spatial scale (0.7-600 km), environmental distance,
quantitative (QST) and neutral (FST) genetic differentiation, and size of the
local and foreign populations could predict patterns of adaptive differentiation.
Local adaptation varied among populations and fitness components. Including all
population pairs, local adaptation was observed for seedling survival, but not
for biomass, while foreign genotype advantage was observed for reproduction (number
of inflorescences). Among population pairs, local adaptation increased with QST
and local population size for biomass. QST was associated with environmental distance,
suggesting ecological selection for phenotypic divergence. However, low FST and
variation in population structure in small populations demonstrates the interaction
of gene flow and drift in constraining local adaptation in R. leptorrhynchoides.
Our study indicates that for species in heterogeneous landscapes, collecting seed
from large populations from similar environments to candidate sites is likely
to provide the most appropriate seed sources for restoration.

text: 'We study the expressive power of logical interpretations on the class of
scattered trees, namely those with countably many infinite branches. Scattered
trees can be thought of as the tree analogue of scattered linear orders. Every
scattered tree has an ordinal rank that reflects the structure of its infinite
branches. We prove, roughly, that trees and orders of large rank cannot be interpreted
in scattered trees of small rank. We consider a quite general notion of interpretation:
each element of the interpreted structure is represented by a set of tuples of
subsets of the interpreting tree. Our trees are countable, not necessarily finitely
branching, and may have finitely many unary predicates as labellings. We also
show how to replace injective set-interpretations in (not necessarily scattered)
trees by ''finitary'' set-interpretations.'

text: We solve the longstanding open problems of the blow-up involved in the translations,
when possible, of a nondeterministic Büchi word automaton (NBW) to a nondeterministic
co-Büchi word automaton (NCW) and to a deterministic co-Büchi word automaton (DCW).
For the NBW to NCW translation, the currently known upper bound is 2o(nlog n)
and the lower bound is 1.5n. We improve the upper bound to n2n and describe a
matching lower bound of 2ω(n). For the NBW to DCW translation, the currently known
upper bound is 2o(nlog n). We improve it to 2 o(n), which is asymptotically tight.
Both of our upper-bound constructions are based on a simple subset construction,
do not involve intermediate automata with richer acceptance conditions, and can
be implemented symbolically. We continue and solve the open problems of translating
nondeterministic Streett, Rabin, Muller, and parity word automata to NCW and to
DCW. Going via an intermediate NBW is not optimal and we describe direct, simple,
and asymptotically tight constructions, involving a 2o(n) blow-up. The constructions
are variants of the subset construction, providing a unified approach for translating
all common classes of automata to NCW and DCW. Beyond the theoretical importance
of the results, we point to numerous applications of the new constructions. In
particular, they imply a simple subset-construction based translation, when possible,
of LTL to deterministic Büchi word automata.

text: 'One central issue in the formal design and analysis of reactive systems is
the notion of refinement that asks whether all behaviors of the implementation
is allowed by the specification. The local interpretation of behavior leads to
the notion of simulation. Alternating transition systems (ATSs) provide a general
model for composite reactive systems, and the simulation relation for ATSs is
known as alternating simulation. The simulation relation for fair transition systems
is called fair simulation. In this work our main contributions are as follows:
(1) We present an improved algorithm for fair simulation with Büchi fairness constraints;
our algorithm requires O(n 3·m) time as compared to the previous known O(n 6)-time
algorithm, where n is the number of states and m is the number of transitions.
(2) We present a game based algorithm for alternating simulation that requires
O(m2)-time as compared to the previous known O((n·m)2)-time algorithm, where n
is the number of states and m is the size of transition relation. (3) We present
an iterative algorithm for alternating simulation that matches the time complexity
of the game based algorithm, but is more space efficient than the game based algorithm.

text: Computing the winning set for Büchi objectives in alternating games on graphs
is a central problem in computer aided verification with a large number of applications.
The long standing best known upper bound for solving the problem is Õ(n·m), where
n is the number of vertices and m is the number of edges in the graph. We are
the first to break the Õ(n·m) boundary by presenting a new technique that reduces
the running time to O(n 2). This bound also leads to O(n 2) time algorithms for
computing the set of almost-sure winning vertices for Büchi objectives (1) in
alternating games with probabilistic transitions (improving an earlier bound of
Õ(n·m)), (2) in concurrent graph games with constant actions (improving an earlier
bound of O(n 3)), and (3) in Markov decision processes (improving for m > n
4/3 an earlier bound of O(min(m 1.5, m·n 2/3)). We also show that the same technique
can be used to compute the maximal end-component decomposition of a graph in time
O(n 2), which is an improvement over earlier bounds for m > n 4/3. Finally,
we show how to maintain the winning set for Büchi objectives in alternating games
under a sequence of edge insertions or a sequence of edge deletions in O(n) amortized
time per operation. This is the first dynamic algorithm for this problem.

text: 'Two-player games on graphs are central in many problems in formal verification
and program analysis such as synthesis and verification of open systems. In this
work we consider solving recursive game graphs (or pushdown game graphs) that
can model the control flow of sequential programs with recursion. While pushdown
games have been studied before with qualitative objectives, such as reachability
and parity objectives, in this work we study for the first time such games with
the most well-studied quantitative objective, namely, mean payoff objectives.
In pushdown games two types of strategies are relevant: (1) global strategies,
that depend on the entire global history; and (2) modular strategies, that have
only local memory and thus do not depend on the context of invocation, but only
on the history of the current invocation of the module. Our main results are as
follows: (1) One-player pushdown games with mean-payoff objectives under global
strategies are decidable in polynomial time. (2) Two-player pushdown games with
mean-payoff objectives under global strategies are undecidable. (3) One-player
pushdown games with mean-payoff objectives under modular strategies are NP-hard.
(4) Two-player pushdown games with mean-payoff objectives under modular strategies
can be solved in NP (i.e., both one-player and two-player pushdown games with
mean-payoff objectives under modular strategies are NP-complete). We also establish
the optimal strategy complexity showing that global strategies for mean-payoff
objectives require infinite memory even in one-player pushdown games; and memoryless
modular strategies are sufficient in two-player pushdown games. Finally we also
show that all the problems have the same computational complexity if the stack
boundedness condition is added, where along with the mean-payoff objective the
player must also ensure that the stack height is bounded.'

work we consider solving recursive game graphs (or pushdown game graphs) that
can model the control flow of sequential programs with recursion. While pushdown
games have been studied before with qualitative objectives, such as reachability
and ω-regular objectives, in this work we study for the first time such games
with the most well-studied quantitative objective, namely, mean-payoff objectives.
In pushdown games two types of strategies are relevant: (1) global strategies,
that depend on the entire global history; and (2) modular strategies, that have
only local memory and thus do not depend on the context of invocation, but only
on the history of the current invocation of the module. Our main results are as
follows: (1) One-player pushdown games with mean-payoff objectives under global
strategies are decidable in polynomial time. (2) Two- player pushdown games with
mean-payoff objectives under global strategies are undecidable. (3) One-player
pushdown games with mean-payoff objectives under modular strategies are NP- hard.
(4) Two-player pushdown games with mean-payoff objectives under modular strategies
can be solved in NP (i.e., both one-player and two-player pushdown games with
mean-payoff objectives under modular strategies are NP-complete). We also establish
the optimal strategy complexity showing that global strategies for mean-payoff
objectives require infinite memory even in one-player pushdown games; and memoryless
modular strategies are sufficient in two- player pushdown games. Finally we also
show that all the problems have the same complexity if the stack boundedness condition
is added, where along with the mean-payoff objective the player must also ensure
that the stack height is bounded.'

text: 'One central issue in the formal design and analysis of reactive systems is
the notion of refinement that asks whether all behaviors of the implementation
is allowed by the specification. The local interpretation of behavior leads to
the notion of simulation. Alternating transition systems (ATSs) provide a general
model for composite reactive systems, and the simulation relation for ATSs is
known as alternating simulation. The simulation relation for fair transition systems
is called fair simulation. In this work our main contributions are as follows:
(1) We present an improved algorithm for fair simulation with Büchi fairness constraints;
our algorithm requires O(n3 · m) time as compared to the previous known O(n6)-time
algorithm, where n is the number of states and m is the number of transitions.
(2) We present a game based algorithm for alternating simulation that requires
O(m2)-time as compared to the previous known O((n · m)2)-time algorithm, where
n is the number of states and m is the size of transition relation. (3) We present
an iterative algorithm for alternating simulation that matches the time complexity
of the game based algorithm, but is more space efficient than the game based algorithm.'

text: 'We consider two-player stochastic games played on finite graphs with reachability
objectives where the first player tries to ensure a target state to be visited
almost-surely (i.e., with probability 1), or positively (i.e., with positive probability),
no matter the strategy of the second player. We classify such games according
to the information and the power of randomization available to the players. On
the basis of information, the game can be one-sided with either (a) player 1,
or (b) player 2 having partial observation (and the other player has perfect observation),
or two-sided with (c) both players having partial observation. On the basis of
randomization, the players (a) may not be allowed to use randomization (pure strategies),
or (b) may choose a probability distribution over actions but the actual random
choice is external and not visible to the player (actions invisible), or (c) may
use full randomization. Our main results for pure strategies are as follows. (1)
For one-sided games with player 1 having partial observation we show that (in
contrast to full randomized strategies) belief-based (subset-construction based)
strategies are not sufficient, and we present an exponential upper bound on memory
both for almostsure and positive winning strategies; we show that the problem
of deciding the existence of almost-sure and positive winning strategies for player
1 is EXPTIME-complete. (2) For one-sided games with player 2 having partial observation
we show that non-elementary memory is both necessary and sufficient for both almost-sure
and positive winning strategies. (3) We show that for the general (two-sided)
case finite-memory strategies are sufficient for both positive and almost-sure
winning, and at least non-elementary memory is required. We establish the equivalence
of the almost-sure winning problems for pure strategies and for randomized strategies
with actions invisible. Our equivalence result exhibits serious flaws in previous
results of the literature: we show a non-elementary memory lower bound for almost-sure
winning whereas an exponential upper bound was previously claimed.'

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

text: 'We consider probabilistic automata on infinite words with acceptance defined
by parity conditions. We consider three qualitative decision problems: (i) the
positive decision problem asks whether there is a word that is accepted with positive
probability; (ii) the almost decision problem asks whether there is a word that
is accepted with probability 1; and (iii) the limit decision problem asks whether
words are accepted with probability arbitrarily close to 1. We unify and generalize
several decidability results for probabilistic automata over infinite words, and
identify a robust (closed under union and intersection) subclass of probabilistic
automata for which all the qualitative decision problems are decidable for parity
conditions. We also show that if the input words are restricted to lasso shape
(regular) words, then the positive and almost problems are decidable for all probabilistic
automata with parity conditions. For most decidable problems we show an optimal
PSPACE-complete complexity bound.'

text: Boolean notions of correctness are formalized by preorders on systems. Quantitative
measures of correctness can be formalized by real-valued distance functions between
systems, where the distance between implementation and specification provides
a measure of "fit" or "desirability". We extend the simulation
preorder to the quantitative setting by making each player of a simulation game
pay a certain price for her choices. We use the resulting games with quantitative
objectives to define three different simulation distances. The correctness distance
measures how much the specification must be changed in order to be satisfied by
the implementation. The coverage distance measures how much the implementation
restricts the degrees of freedom offered by the specification. The robustness
distance measures how much a system can deviate from the implementation description
without violating the specification. We consider these distances for safety as
well as liveness specifications. The distances can be computed in polynomial time
for safety specifications, and for liveness specifications given by weak fairness
constraints. We show that the distance functions satisfy the triangle inequality,
that the distance between two systems does not increase under parallel composition
with a third system, and that the distance between two systems can be bounded
from above and below by distances between abstractions of the two systems. These
properties suggest that our simulation distances provide an appropriate basis
for a quantitative theory of discrete systems. We also demonstrate how the robustness
distance can be used to measure how many transmission errors are tolerated by
error correcting codes.

text: The human Mediator complex controls RNA polymerase II (pol II) function in
ways that remain incompletely understood. Activator-Mediator binding alters Mediator
structure, and these activator-induced structural shifts appear to play key roles
in regulating transcription. A recent cryo-electron microscopy (EM) analysis revealed
that pol II adopted a stable orientation within a Mediator-pol II-TFIIF assembly
in which Mediator was bound to the activation domain of viral protein 16 (VP16).
Whereas TFIIF was shown to be important for orienting pol II within this assembly,
the potential role of the activator was not assessed. To determine how activator
binding might affect pol II orientation, we isolated human Mediator-pol II-TFIIF
complexes in which Mediator was not bound to an activator. Cryo-EM analysis of
this assembly, coupled with pol II crystal structure docking, revealed that pol
II binds Mediator at the same general location; however, in contrast to VP16-bound
Mediator, pol II does not appear to stably orient in the absence of an activator.
Variability in pol II orientation might be important mechanistically, perhaps
to enable sense and antisense transcription at human promoters. Because Mediator
interacts extensively with pol II, these results suggest that Mediator structural
shifts induced by activator binding help stably orient pol II prior to transcription
initiation.

text: Tonic receptors convey stimulus duration and intensity and are implicated
in homeostatic control. However, how tonic homeostatic signals are generated and
how they reconfigure neural circuits and modify animal behavior is poorly understood.
Here we show that Caenorhabditis elegans O2-sensing neurons are tonic receptors
that continuously signal ambient [O2] to set the animal's behavioral state. Sustained
signaling relied on a Ca2+ relay involving L-type voltage-gated Ca2+ channels,
the ryanodine and the inositol-1,4,5-trisphosphate receptors. Tonic activity evoked
continuous neuropeptide release, which helps elicit the enduring behavioral state
associated with high [O2]. Sustained O2 receptor signaling was propagated to downstream
neural circuits, including the hub interneuron RMG. O2 receptors evoked similar
locomotory states at particular O2 concentrations, regardless of previous d[O2]/dt.
However, a phasic component of the URX receptors' response to high d[O2]/dt, as
well as tonic-to-phasic transformations in downstream interneurons, enabled transient
reorientation movements shaped by d[O2]/dt. Our results highlight how tonic homeostatic
signals can generate both transient and enduring behavioral change.

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

text: The Seebeck coefficients, electrical resistivities, total thermal conductivities,
and magnetization are reported for temperatures between 5 and 350 K for n-type
Bi0.88Sb0.12 nano-composite alloys made by Ho-doping at the 0, 1, and 3 % atomic
levels. The alloys were prepared using a dc hot-pressing method, and are shown
to be single phase for both Ho contents with grain sizes on the average of 900
nm. We find the parent compound has a maximum of ZT = 0.28 at 231 K, while doping
1 % Ho increases the maximum ZT to 0.31 at 221 K and the 3 % doped sample suppresses
the maximum ZT = 0.24 at a temperature of 260 K.

text: 'Carbon has been used widely as the basis of porous cathodes for nonaqueous
Li–O2 cells. However, the stability of carbon and the effect of carbon on electrolyte
decomposition in such cells are complex and depend on the hydrophobicity/hydrophilicity
of the carbon surface. Analyzing carbon cathodes, cycled in Li–O2 cells between
2 and 4 V, using acid treatment and Fenton’s reagent, and combined with differential
electrochemical mass spectrometry and FTIR, demonstrates the following: Carbon
is relatively stable below 3.5 V (vs Li/Li+) on discharge or charge, especially
so for hydrophobic carbon, but is unstable on charging above 3.5 V (in the presence
of Li2O2), oxidatively decomposing to form Li2CO3. Direct chemical reaction with
Li2O2 accounts for only a small proportion of the total carbon decomposition on
cycling. Carbon promotes electrolyte decomposition during discharge and charge
in a Li–O2 cell, giving rise to Li2CO3 and Li carboxylates (DMSO and tetraglyme
electrolytes). The Li2CO3 and Li carboxylates present at the end of discharge
and those that form on charge result in polarization on the subsequent charge.
Li2CO3 (derived from carbon and from the electrolyte) as well as the Li carboxylates
(derived from the electrolyte) decompose and form on charging. Oxidation of Li2CO3
on charging to ∼4 V is incomplete; Li2CO3 accumulates on cycling resulting in
electrode passivation and capacity fading. Hydrophilic carbon is less stable and
more catalytically active toward electrolyte decomposition than carbon with a
hydrophobic surface. If the Li–O2 cell could be charged at or below 3.5 V, then
carbon may be relatively stable, however, its ability to promote electrolyte decomposition,
presenting problems for its use in a practical Li–O2 battery. The results emphasize
that stable cycling of Li2O2 at the cathode in a Li–O2 cell depends on the synergy
between electrolyte and electrode; the stability of the electrode and the electrolyte
cannot be considered in isolation.'

text: Energy‐storage technologies, including electrical double‐layer capacitors
and rechargeable batteries, have attracted significant attention for applications
in portable electronic devices, electric vehicles, bulk electricity storage at
power stations, and “load leveling” of renewable sources, such as solar energy
and wind power. Transforming lithium batteries and electric double‐layer capacitors
requires a step change in the science underpinning these devices, including the
discovery of new materials, new electrochemistry, and an increased understanding
of the processes on which the devices depend. The Review will consider some of
the current scientific issues underpinning lithium batteries and electric double‐layer
capacitors.

text: The rechargeable nonaqueous lithium-air (Li-O2) battery is receiving a great
deal of interest because, theoretically, its specific energy far exceeds the best
that can be achieved with lithium-ion cells. Operation of the rechargeable Li-O2
battery depends critically on repeated and highly reversible formation/decomposition
of lithium peroxide (Li2O2) at the cathode upon cycling. Here, we show that this
process is possible with the use of a dimethyl sulfoxide electrolyte and a porous
gold electrode (95% capacity retention from cycles 1 to 100), whereas previously
only partial Li2O2 formation/decomposition and limited cycling could occur. Furthermore,
we present data indicating that the kinetics of Li2O2 oxidation on charge is approximately
10 times faster than on carbon electrodes.

text: Stability of the electrolyte toward reduced oxygen species generated at the
cathode is a crucial challenge for the rechargeable nonaqueous Li–O2 battery.
Here, we investigate dimethylformamide as the basis of an electrolyte. Although
reactions at the O2 cathode on the first discharge–charge cycle are dominated
by reversible Li2O2 formation/decomposition, there is also electrolyte decomposition,
which increases on cycling. The products of decomposition at the cathode on discharge
are Li2O2, Li2CO3, HCO2Li, CH3CO2Li, NO, H2O, and CO2. Li2CO3 accumulates in the
electrode with cycling. The stability of dimethylformamide toward reduced oxygen
species is insufficient for its use in the rechargeable nonaqueous Li–O2 battery.

text: Decades of research in distributed computing have led to a variety of perspectives
on what it means for a concurrent algorithm to be efficient, depending on model
assumptions, progress guarantees, and complexity metrics. It is therefore natural
to ask whether one could compose algorithms that perform efficiently under different
conditions, so that the composition preserves the performance of the original
components when their conditions are met. In this paper, we evaluate the cost
of composing shared-memory algorithms. First, we formally define the notion of
safely composable algorithms and we show that every sequential type has a safely
composable implementation, as long as enough state is transferred between modules.
Since such generic implementations are inherently expensive, we present a more
general light-weight specification that allows the designer to transfer very little
state between modules, by taking advantage of the semantics of the implemented
object. Using this framework, we implement a composed longlived test-and-set object,
with the property that each of its modules is asymptotically optimal with respect
to the progress condition it ensures, while the entire implementation only uses
objects with consensus number at most two. Thus, we show that the overhead of
composition can be negligible in the case of some important shared-memory abstractions.

text: Renaming is a fundamental problem in distributed computing, in which a set
of n processes need to pick unique names from a namespace of limited size. In
this paper, we present the first early-deciding upper bounds for synchronous renaming,
in which the running time adapts to the actual number of failures f in the execution.
We show that, surprisingly, renaming can be solved in constant time if the number
of failures f is limited to O(√n), while for general f ≤ n - 1 renaming can always
be solved in O(log f) communication rounds. In the wait-free case, i.e. for f
= n - 1, our upper bounds match the Ω(log n) lower bound of Chaudhuri et al. [13].
