text: We study synthesis of controllers for real-time systems, where the objective
is to stay in a given safe set. The problem is solved by obtaining winning strategies
in the setting of concurrent two player timed automaton games with safety objectives.
To prevent a player from winning by blocking time, we restrict each player to
strategies that ensure that the player cannot be responsible for causing a Zeno
run. We construct winning strategies for the controller which require access only
to (1) the system clocks (thus, controllers which require their own internal infinitely
precise clocks are not necessary), and (2) a logarithmic (in the number of clocks)
number of memory bits (i.e. a linear number of memory states). Precisely, we show
that for safety objectives, a memory of size (3 + lg (| C | + 1)) bits suffices
for winning controller strategies, where C is the set of clocks of the timed automaton
game, significantly improving the previous known exponential memory states bound.
We also settle the open question of whether winning region-based strategies require
memory for safety objectives by showing with an example the necessity of memory
for such strategies to win for safety objectives. Finally, we show that the decision
problem of determining if there exists a receptive player-1 winning strategy for
safety objectives is EXPTIME-complete over timed automaton games.

text: PIN-FORMED (PIN) proteins localize asymmetrically at the plasma membrane and
mediate intercellular polar transport of the plant hormone auxin that is crucial
for a multitude of developmental processes in plants. PIN localization is under
extensive control by environmental or developmental cues, but mechanisms regulating
PIN localization are not fully understood. Here we show that early endosomal components
ARF GEF BEN1 and newly identified Sec1/Munc18 family protein BEN2 are involved
in distinct steps of early endosomal trafficking. BEN1 and BEN2 are collectively
required for polar PIN localization, for their dynamic repolarization, and consequently
for auxin activity gradient formation and auxin-related developmental processes
including embryonic patterning, organogenesis, and vasculature venation patterning.
These results show that early endosomal trafficking is crucial for cell polarity
and auxin-dependent regulation of plant architecture.

text: 'We study the complexity of valued constraint satisfaction problems (VCSPs)
parametrized by a constraint language, a fixed set of cost functions over a finite
domain. An instance of the problem is specified by a sum of cost functions from
the language and the goal is to minimize the sum. Under the unique games conjecture,
the approximability of finite-valued VCSPs is well understood, see Raghavendra
[2008]. However, there is no characterization of finite-valued VCSPs, let alone
general-valued VCSPs, that can be solved exactly in polynomial time, thus giving
insights from a combinatorial optimization perspective. We consider the case of
languages containing all possible unary cost functions. In the case of languages
consisting of only {0, ∞}-valued cost functions (i.e., relations), such languages
have been called conservative and studied by Bulatov [2003, 2011] and recently
by Barto [2011]. Since we study valued languages, we call a language conservative
if it contains all finite-valued unary cost functions. The computational complexity
of conservative valued languages has been studied by Cohen et al. [2006] for languages
over Boolean domains, by Deineko et al. [2008] for {0, 1}-valued languages (a.k.a
Max-CSP), and by Takhanov [2010a] for {0, ∞}-valued languages containing all finite-valued
unary cost functions (a.k.a. Min-Cost-Hom). We prove a Schaefer-like dichotomy
theorem for conservative valued languages: if all cost functions in the language
satisfy a certain condition (specified by a complementary combination of STP and
MJN multimor-phisms), then any instance can be solved in polynomial time (via
a new algorithm developed in this article), otherwise the language is NP-hard.
This is the first complete complexity classification of general-valued constraint
languages over non-Boolean domains. It is a common phenomenon that complexity
classifications of problems over non-Boolean domains are significantly harder
than the Boolean cases. The polynomial-time algorithm we present for the tractable
cases is a generalization of the submodular minimization problem and a result
of Cohen et al. [2008]. Our results generalize previous results by Takhanov [2010a]
and (a subset of results) by Cohen et al. [2006] and Deineko et al. [2008]. Moreover,
our results do not rely on any computer-assisted search as in Deineko et al. [2008],
and provide a powerful tool for proving hardness of finite-valued and general-valued
languages.'

text: Laminar-turbulent intermittency is intrinsic to the transitional regime of
a wide range of fluid flows including pipe, channel, boundary layer, and Couette
flow. In the latter turbulent spots can grow and form continuous stripes, yet
in the stripe-normal direction they remain interspersed by laminar fluid. We carry
out direct numerical simulations in a long narrow domain and observe that individual
turbulent stripes are transient. In agreement with recent observations in pipe
flow, we find that turbulence becomes sustained at a distinct critical point once
the spatial proliferation outweighs the inherent decaying process. By resolving
the asymptotic size distributions close to criticality we can for the first time
demonstrate scale invariance at the onset of turbulence.

text: Although the equations governing fluid flow are well known, there are no analytical
expressions that describe the complexity of turbulent motion. A recent proposition
is that in analogy to low dimensional chaotic systems, turbulence is organized
around unstable solutions of the governing equations which provide the building
blocks of the disordered dynamics. We report the discovery of periodic solutions
which just like intermittent turbulence are spatially localized and show that
turbulent transients arise from one such solution branch.

text: During development, mechanical forces cause changes in size, shape, number,
position, and gene expression of cells. They are therefore integral to any morphogenetic
processes. Force generation by actin-myosin networks and force transmission through
adhesive complexes are two self-organizing phenomena driving tissue morphogenesis.
Coordination and integration of forces by long-range force transmission and mechanosensing
of cells within tissues produce large-scale tissue shape changes. Extrinsic mechanical
forces also control tissue patterning by modulating cell fate specification and
differentiation. Thus, the interplay between tissue mechanics and biochemical
signaling orchestrates tissue morphogenesis and patterning in development.

text: 'We outline two approaches to inference of neighbourhood size, N, and dispersal
rate, σ2, based on either allele frequencies or on the lengths of sequence blocks
that are shared between genomes. Over intermediate timescales (10-100 generations,
say), populations that live in two dimensions approach a quasi-equilibrium that
is independent of both their local structure and their deeper history. Over such
scales, the standardised covariance of allele frequencies (i.e. pairwise FS T)
falls with the logarithm of distance, and depends only on neighbourhood size,
N, and a ''local scale'', κ; the rate of gene flow, σ2, cannot be inferred. We
show how spatial correlations can be accounted for, assuming a Gaussian distribution
of allele frequencies, giving maximum likelihood estimates of N and κ. Alternatively,
inferences can be based on the distribution of the lengths of sequence that are
identical between blocks of genomes: long blocks (>0.1 cM, say) tell us about
intermediate timescales, over which we assume a quasi-equilibrium. For large neighbourhood
size, the distribution of long blocks is given directly by the classical Wright-Malécot
formula; this relationship can be used to infer both N and σ2. With small neighbourhood
size, there is an appreciable chance that recombinant lineages will coalesce back
before escaping into the distant past. For this case, we show that if genomes
are sampled from some distance apart, then the distribution of lengths of blocks
that are identical in state is geometric, with a mean that depends on N and σ2.'

text: Individuals with Down syndrome (DS) present important motor deficits that
derive from altered motor development of infants and young children. DYRK1A, a
candidate gene for DS abnormalities has been implicated in motor function due
to its expression in motor nuclei in the adult brain, and its overexpression in
DS mouse models leads to hyperactivity and altered motor learning. However, its
precise role in the adult motor system, or its possible involvement in postnatal
locomotor development has not yet been clarified. During the postnatal period
we observed time-specific expression of Dyrk1A in discrete subsets of brainstem
nuclei and spinal cord motor neurons. Interestingly, we describe for the first
time the presence of Dyrk1A in the presynaptic terminal of the neuromuscular junctions
and its axonal transport from the facial nucleus, suggesting a function for Dyrk1A
in these structures. Relevant to DS, Dyrk1A overexpression in transgenic mice
(TgDyrk1A) produces motor developmental alterations possibly contributing to DS
motor phenotypes and modifies the numbers of motor cholinergic neurons, suggesting
that the kinase may have a role in the development of the brainstem and spinal
cord motor system.

text: Directional guidance of cells via gradients of chemokines is considered crucial
for embryonic development, cancer dissemination, and immune responses. Nevertheless,
the concept still lacks direct experimental confirmation in vivo. Here, we identify
endogenous gradients of the chemokine CCL21 within mouse skin and show that they
guide dendritic cells toward lymphatic vessels. Quantitative imaging reveals depots
of CCL21 within lymphatic endothelial cells and steeply decaying gradients within
the perilymphatic interstitium. These gradients match the migratory patterns of
the dendritic cells, which directionally approach vessels from a distance of up
to 90-micrometers. Interstitial CCL21 is immobilized to heparan sulfates, and
its experimental delocalization or swamping the endogenous gradients abolishes
directed migration. These findings functionally establish the concept of haptotaxis,
directed migration along immobilized gradients, in tissues.
