text: 'Random genetic drift shifts clines in space, alters their width, and distorts
their shape. Such random fluctuations complicate inferences from cline width and
position. Notably, the effect of genetic drift on the expected shape of the cline
is opposite to the naive (but quite common) misinterpretation of classic results
on the expected cline. While random drift on average broadens the overall cline
in expected allele frequency, it narrows the width of any particular cline. The
opposing effects arise because locally, drift drives alleles to fixation—but fluctuations
in position widen the expected cline. The effect of genetic drift can be predicted
from standardized variance in allele frequencies, averaged across the habitat:
〈F〉. A cline maintained by spatially varying selection (step change) is expected
to be narrower by a factor of relative to the cline in the absence of drift.
The expected cline is broader by the inverse of this factor. In a tension zone
maintained by underdominance, the expected cline width is narrower by about 1
– 〈F〉relative to the width in the absence of drift. Individual clines can differ
substantially from the expectation, and we give quantitative predictions for the
variance in cline position and width. The predictions apply to clines in almost
one-dimensional circumstances such as hybrid zones in rivers, deep valleys, or
along a coast line and give a guide to what patterns to expect in two dimensions.'

text: Defining population structure and genetic diversity levels is of the utmost
importance for developing efficient conservation strategies. Overfishing has caused
mean annual catches of the European spiny lobster (Palinurus elephas) to decrease
alarmingly along its distribution area. In this context, there is a need for comprehensive
studies aiming to evaluate the genetic health of the exploited populations. The
present study is based on a set of ten nuclear markers amplified in 331 individuals
from ten different localities covering most of P. elephas distribution area. Samples
from Atlantic and Mediterranean basins showed small but significant differences,
indicating that P. elephas populations do not behave as a single panmictic unit
but form two partially-overlapping groups. Despite intense overfishing, our dataset
did not recover a recent bottleneck signal, and instead showed a large and stable
historical effective size. This result could be accounted for by specific life-history
traits (reproduction and longevity) and the limitations of molecular markers in
covering recent timescales for nontemporal samples. The findings of the present
study emphasize the need to integrate information on effective population sizes
and life-history parameters when evaluating population connectivity levels from
genetic data.

text: Facial branchiomotor neurons (FBMNs) in zebrafish and mouse embryonic hindbrain
undergo a characteristic tangential migration from rhombomere (r) 4, where they
are born, to r6/7. Cohesion among neuroepithelial cells (NCs) has been suggested
to function in FBMN migration by inhibiting FBMNs positioned in the basal neuroepithelium
such that they move apically between NCs towards the midline of the neuroepithelium
instead of tangentially along the basal side of the neuroepithelium towards r6/7.
However, direct experimental evaluation of this hypothesis is still lacking. Here,
we have used a combination of biophysical cell adhesion measurements and high-resolution
time-lapse microscopy to determine the role of NC cohesion in FBMN migration.
We show that reducing NC cohesion by interfering with Cadherin 2 (Cdh2) activity
results in FBMNs positioned at the basal side of the neuroepithelium moving apically
towards the neural tube midline instead of tangentially towards r6/7. In embryos
with strongly reduced NC cohesion, ectopic apical FBMN movement frequently results
in fusion of the bilateral FBMN clusters over the apical midline of the neural
tube. By contrast, reducing cohesion among FBMNs by interfering with Contactin
2 (Cntn2) expression in these cells has little effect on apical FBMN movement,
but reduces the fusion of the bilateral FBMN clusters in embryos with strongly
diminished NC cohesion. These data provide direct experimental evidence that NC
cohesion functions in tangential FBMN migration by restricting their apical movement.

text: Recent advances in microscopy techniques and biophysical measurements have
provided novel insight into the molecular, cellular and biophysical basis of cell
adhesion. However, comparably little is known about a core element of cell–cell
adhesion—the energy of adhesion at the cell–cell contact. In this review, we discuss
approaches to understand the nature and regulation of adhesion energy, and propose
strategies to determine adhesion energy between cells in vitro and in vivo.

text: Context-dependent adjustment of mating tactics can drastically increase the
mating success of behaviourally flexible animals. We used the ant Cardiocondyla
obscurior as a model system to study adaptive adjustment of male mating tactics.
This species shows a male diphenism of wingless fighter males and peaceful winged
males. Whereas the wingless males stay and exclusively mate in the maternal colony,
the mating behaviour of winged males is plastic. They copulate with female sexuals
in their natal nests early in life but later disperse in search for sexuals outside.
In this study, we observed the nest-leaving behaviour of winged males under different
conditions and found that they adaptively adjust the timing of their dispersal
to the availability of mating partners, as well as the presence, and even the
type of competitors in their natal nests. In colonies with virgin female queens
winged males stayed longest when they were the only male in the nest. They left
earlier when mating partners were not available or when other males were present.
In the presence of wingless, locally mating fighter males, winged males dispersed
earlier than in the presence of docile, winged competitors. This suggests that
C. obscurior males are capable of estimating their local breeding chances and
adaptively adjust their dispersal behaviour in both an opportunistic and a risk-sensitive
way, thus showing hitherto unknown behavioural plasticity in social insect males.

text: Glutamate is the major excitatory neurotransmitter in the mammalian central
nervous system and gates non-selective cation channels. The origins of glutamate
receptors are not well understood as they differ structurally and functionally
from simple bacterial ligand-gated ion channels. Here we report the discovery
of an ionotropic glutamate receptor that combines the typical eukaryotic domain
architecture with the 'TXVGYG' signature sequence of the selectivity filter found
in K+ channels. This receptor exhibits functional properties intermediate between
bacterial and eukaryotic glutamate-gated ion channels, suggesting a link in the
evolution of ionotropic glutamate receptors.

text: This paper presents a method to create a model of an articulated object using
the planar motion in an initialization video. The model consists of rigid parts
connected by points of articulation. The rigid parts are described by the positions
of salient feature-points tracked throughout the video. Following a filtering
step that identifies points that belong to different objects, rigid parts are
found by a grouping process in a graph pyramid. Valid articulation points are
selected by verifying multiple hypotheses for each pair of parts.

text: Imprinted genes are expressed primarily or exclusively from either the maternal
or paternal allele, a phenomenon that occurs in flowering plants and mammals.
Flowering plant imprinted gene expression has been described primarily in endosperm,
a terminal nutritive tissue consumed by the embryo during seed development or
after germination. Imprinted expression in Arabidopsis thaliana endosperm is orchestrated
by differences in cytosine DNA methylation between the paternal and maternal genomes
as well as by Polycomb group proteins. Currently, only 11 imprinted A. thaliana
genes are known. Here, we use extensive sequencing of cDNA libraries to identify
9 paternally expressed and 34 maternally expressed imprinted genes in A. thaliana
endosperm that are regulated by the DNA-demethylating glycosylase DEMETER, the
DNA methyltransferase MET1, and/or the core Polycomb group protein FIE. These
genes encode transcription factors, proteins involved in hormone signaling, components
of the ubiquitin protein degradation pathway, regulators of histone and DNA methylation,
and small RNA pathway proteins. We also identify maternally expressed genes that
may be regulated by unknown mechanisms or deposited from maternal tissues. We
did not detect any imprinted genes in the embryo. Our results show that imprinted
gene expression is an extensive mechanistically complex phenomenon that likely
affects multiple aspects of seed development.

text: Defining population structure and genetic diversity levels is of the utmost
importance for developing efficient conservation strategies. Overfishing has caused
mean annual catches of the European spiny lobster (Palinurus elephas) to decrease
alarmingly along its distribution area. In this context, there is a need for comprehensive
studies to evaluate the genetic health of the exploited populations. The present
work is based on a set of 10 nuclear markers amplified in 331 individuals from
10 different localities covering most of P. elephas distribution area. Samples
from Atlantic and Mediterranean basins showed small but significant differences,
indicating that P. elephas populations do not behave as a single panmictic unit
but form two partially-overlapping groups. Despite intense overfishing, our dataset
did not recover a recent bottleneck signal, and showed a large and stable historical
effective size instead. This result could be accounted for by specific life history
traits (reproduction and longevity) and the limitations of molecular markers in
covering very recent timescales for non temporal samples. Our study emphasizes
the necessity of integrating information on effective population sizes and life
history parameters when evaluating population connectivity levels from genetic
data.

text: 'Spontaneous release of glutamate is important for maintaining synaptic strength
and controlling spike timing in the brain. Mechanisms regulating spontaneous exocytosis
remain poorly understood. Extracellular calcium concentration ([Ca2+]o) regulates
Ca2+ entry through voltage-activated calcium channels (VACCs) and consequently
is a pivotal determinant of action potential-evoked vesicle fusion. Extracellular
Ca 2+ also enhances spontaneous release, but via unknown mechanisms. Here we report
that external Ca2+ triggers spontaneous glutamate release more weakly than evoked
release in mouse neocortical neurons. Blockade of VACCs has no effect on the spontaneous
release rate or its dependence on [Ca2+]o. Intracellular [Ca2+] slowly increases
in a minority of neurons following increases in [Ca2+]o. Furthermore, the enhancement
of spontaneous release by extracellular calcium is insensitive to chelation of
intracellular calcium by BAPTA. Activation of the calcium-sensing receptor (CaSR),
a G-protein-coupled receptor present in nerve terminals, by several specific agonists
increased spontaneous glutamate release. The frequency of spontaneous synaptic
transmission was decreased in CaSR mutant neurons. The concentration-effect relationship
for extracellular calcium regulation of spontaneous release was well described
by a combination of CaSR-dependent and CaSR-independent mechanisms. Overall these
results indicate that extracellular Ca2+ does not trigger spontaneous glutamate
release by simply increasing calcium influx but stimulates CaSR and thereby promotes
resting spontaneous glutamate release. '

text: 'BioSig is an open source software library for biomedical signal processing.
The aim of the BioSig project is to foster research in biomedical signal processing
by providing free and open source software tools for many different application
areas. Some of the areas where BioSig can be employed are neuroinformatics, brain-computer
interfaces, neurophysiology, psychology, cardiovascular systems, and sleep research.
Moreover, the analysis of biosignals such as the electroencephalogram (EEG), electrocorticogram
(ECoG), electrocardiogram (ECG), electrooculogram (EOG), electromyogram (EMG),
or respiration signals is a very relevant element of the BioSig project. Specifically,
BioSig provides solutions for data acquisition, artifact processing, quality control,
feature extraction, classification, modeling, and data visualization, to name
a few. In this paper, we highlight several methods to help students and researchers
to work more efficiently with biomedical signals. '

text: In their search for antigens, lymphocytes continuously shuttle among blood
vessels, lymph vessels, and lymphatic tissues. Chemokines mediate entry of lymphocytes
into lymphatic tissues, and sphingosine 1-phosphate (S1P) promotes localization
of lymphocytes to the vasculature. Both signals are sensed through G protein-coupled
receptors (GPCRs). Most GPCRs undergo ligand-dependent homologous receptor desensitization,
a process that decreases their signaling output after previous exposure to high
ligand concentration. Such desensitization can explain why lymphocytes do not
take an intermediate position between two signals but rather oscillate between
them. The desensitization of S1P receptor 1 (S1PR1) is mediated by GPCR kinase
2 (GRK2). Deletion of GRK2 in lymphocytes compromises desensitization by high
vascular S1P concentrations, thereby reducing responsiveness to the chemokine
signal and trapping the cells in the vascular compartment. The desensitization
kinetics of S1PR1 allows lymphocytes to dynamically shuttle between vasculature
and lymphatic tissue, although the positional information in both compartments
is static.

text: Cancer stem cells or cancer initiating cells are believed to contribute to
cancer recurrence after therapy. MicroRNAs (miRNAs) are short RNA molecules with
fundamental roles in gene regulation. The role of miRNAs in cancer stem cells
is only poorly understood. Here, we report miRNA expression profiles of glioblastoma
stem cell-containing CD133 + cell populations. We find that miR-9, miR-9 * (referred
to as miR-9/9 *), miR-17 and miR-106b are highly abundant in CD133 + cells. Furthermore,
inhibition of miR-9/9 * or miR-17 leads to reduced neurosphere formation and stimulates
cell differentiation. Calmodulin-binding transcription activator 1 (CAMTA1) is
a putative transcription factor, which induces the expression of the anti-proliferative
cardiac hormone natriuretic peptide A (NPPA). We identify CAMTA1 as an miR-9/9
* and miR-17 target. CAMTA1 expression leads to reduced neurosphere formation
and tumour growth in nude mice, suggesting that CAMTA1 can function as tumour
suppressor. Consistently, CAMTA1 and NPPA expression correlate with patient survival.
Our findings could provide a basis for novel strategies of glioblastoma therapy.

text: Software transactional memories (STM) are described in the literature with
assumptions of sequentially consistent program execution and atomicity of high
level operations like read, write, and abort. However, in a realistic setting,
processors use relaxed memory models to optimize hardware performance. Moreover,
the atomicity of operations depends on the underlying hardware. This paper presents
the first approach to verify STMs under relaxed memory models with atomicity of
32 bit loads and stores, and read-modify-write operations. We describe RML, a
simple language for expressing concurrent programs. We develop a semantics of
RML parametrized by a relaxed memory model. We then present our tool, FOIL, which
takes as input the RML description of an STM algorithm restricted to two threads
and two variables, and the description of a memory model, and automatically determines
the locations of fences, which if inserted, ensure the correctness of the restricted
STM algorithm under the given memory model. We use FOIL to verify DSTM, TL2, and
McRT STM under the memory models of sequential consistency, total store order,
partial store order, and relaxed memory order for two threads and two variables.
Finally, we extend the verification results for DSTM and TL2 to an arbitrary number
of threads and variables by manually proving that the structural properties of
STMs are satisfied at the hardware level of atomicity under the considered relaxed
memory models.

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 ̃O(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 ̃O(n·m) boundary by presenting a new technique that reduces
the running time to O(n2). This bound also leads to O(n2) 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
O(n·m)), (2) in concurrent graph games with constant actions (improving an earlier
bound of O(n3)), and (3) in Markov decision processes (improving for m > n4/3
an earlier bound of O(min(m1.5, m·n2/3)). We also show that the same technique
can be used to compute the maximal end-component decomposition of a graph in time
O(n2), which is an improvement over earlier bounds for m > n4/3. 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: 'We consider 2-player 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 the successor state. We study concurrent games
with ω-regular winning conditions specified as parity objectives. We consider
the qualitative analysis problems: the computation of the almost-sure and limit-sure
winning set of states, where player 1 can ensure to win with probability 1 and
with probability arbitrarily close to 1, respectively. In general the almost-sure
and limit-sure winning strategies require both infinite-memory as well as infinite-precision
(to describe probabilities). We study the bounded-rationality problem for qualitative
analysis of concurrent parity games, where the strategy set for player 1 is restricted
to bounded-resource strategies. In terms of precision, strategies can be deterministic,
uniform, finite-precision or infinite-precision; and in terms of memory, strategies
can be memoryless, finite-memory or infinite-memory. We present a precise and
complete characterization of the qualitative winning sets for all combinations
of classes of strategies. In particular, we show that uniform memoryless strategies
are as powerful as finite-precision infinite-memory strategies, and infinite-precision
memoryless strategies are as powerful as infinite-precision finite-memory strategies. We
show that the winning sets can be computed in O(n2d+3) time, where n is the size
of the game structure and 2d is the number of priorities (or colors), and our
algorithms are symbolic. The membership problem of whether a state belongs to
a winning set can be decided in NP ∩ coNP. While this complexity is the same as
for the simpler class of turn-based parity games, where in each state only one
of the two players has a choice of moves, our algorithms,that are obtained by
characterization of the winning sets as μ-calculus formulas, are considerably
more involved than those for turn-based games.'

text: "In two-player finite-state stochastic games of partial obser- vation on graphs,
in every state of the graph, the players simultaneously choose an action, and
their joint actions determine a probability distri- bution over the successor
states. The game is played for infinitely many rounds and thus the players construct
an infinite path in the graph. We consider reachability objectives where the first
player tries to ensure a target state to be visited almost-surely (i.e., with
probability 1) or pos- itively (i.e., with positive probability), no matter the
strategy of the second player.\r\n\r\nWe classify such games according to the
information and to 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, (a) the players may not be allowed to use randomization (pure strategies),
or (b) they may choose a probability distribution over actions but the actual
random choice is external and not visible to the player (actions invisible), or
(c) they may use full randomization.\r\n\r\nOur main results for pure strategies
are as follows: (1) For one-sided games with player 2 perfect observation we show
that (in contrast to full randomized strategies) belief-based (subset-construction
based) strate- gies are not sufficient, and present an exponential upper bound
on mem- ory both for almost-sure 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 and present symbolic algo- rithms that avoid
the explicit exponential construction. (2) For one-sided games with player 1 perfect
observation we show that non-elementary memory is both necessary and sufficient
for both almost-sure and posi- tive 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 re- sult exhibit
serious flaws in previous results in 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 num- ber 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 ω-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 games with
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 func- tion 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 present a new decidable logic called TREX for expressing constraints about
imperative tree data structures. In particular, TREX supports a transitive closure
operator that can express reachability constraints, which often appear in data
structure invariants. We show that our logic is closed under weakest precondition
computation, which enables its use for automated software verification. We further
show that satisfiability of formulas in TREX is decidable in NP. The low complexity
makes it an attractive alternative to more expensive logics such as monadic second-order
logic (MSOL) over trees, which have been traditionally used for reasoning about
tree data structures.
