text: 'A stochastic game is a two-player game played oil a graph, where in each
state the successor is chosen either by One of the players, or according to a
probability distribution. We Survey Stochastic games with limsup and liminf objectives.
A real-valued re-ward is assigned to each state, and the value of all infinite
path is the limsup (resp. liminf) of all rewards along the path. The value of
a stochastic game is the maximal expected value of an infinite path that call
he achieved by resolving the decisions of the first player. We present the complexity
of computing values of Stochastic games and their subclasses, and the complexity,
of optimal strategies in such games. '

text: "Most specification languages express only qualitative constraints. However,
among two implementations that satisfy a given specification, one may be preferred
to another. For example, if a specification asks that every request is followed
by a response, one may prefer an implementation that generates responses quickly
but does not generate unnecessary responses. We use quantitative properties to
measure the “goodness” of an implementation. Using games with corresponding quantitative
objectives, we can synthesize “optimal” implementations, which are preferred among
the set of possible implementations that satisfy a given specification.\r\nIn
particular, we show how automata with lexicographic mean-payoff conditions can
be used to express many interesting quantitative properties for reactive systems.
In this framework, the synthesis of optimal implementations requires the solution
of lexicographic mean-payoff games (for safety requirements), and the solution
of games with both lexicographic mean-payoff and parity objectives (for liveness
requirements). We present algorithms for solving both kinds of novel graph games."

text: Alpaga is a solver for two-player parity games with imperfect information.
Given the description of a game, it determines whether the first player can ensure
to win and, if so, it constructs a winning strategy. The tool provides a symbolic
implementation of a recent algorithm based on antichains.

by safety, reachability, Büchi, coBüchi and limit-average conditions. We consider
quantitative and qualitative decision problems. We present extensions and adaptations
of proofs of [GO09] and present a precise characterization of the decidability
and undecidability frontier of the quantitative and qualitative decision problems.

text: Gist is a tool that (a) solves the qualitative analysis problem of turn-based
probabilistic games with ω-regular objectives; and (b) synthesizes reasonable
environment assumptions for synthesis of unrealizable specifications. Our tool
provides efficient implementations of several reduction based techniques to solve
turn-based probabilistic games, and uses the analysis of turn-based probabilistic
games for synthesizing environment assumptions for unrealizable specifications.

text: 'We study observation-based strategies for partially-observable Markov decision
processes (POMDPs) with omega-regular objectives. An observation-based strategy
relies on partial information about the history of a play, namely, on the past
sequence of observa- tions. We consider the qualitative analysis problem: given
a POMDP with an omega-regular objective, whether there is an observation-based
strategy to achieve the objective with probability 1 (almost-sure winning), or
with positive probability (positive winning). Our main results are twofold. First,
we present a complete picture of the computational complexity of the qualitative
analysis of POMDPs with parity objectives (a canonical form to express omega-regular
objectives) and its subclasses. Our contribution consists in establishing several
upper and lower bounds that were not known in literature. Second, we present optimal
bounds (matching upper and lower bounds) on the memory required by pure and randomized
observation-based strategies for the qualitative analysis of POMDPs with parity
objectives and its subclasses.'

text: The human CDK8 subcomplex (CDK8, cyclin C, Med12, and Med13) negatively regulates
transcription in ways not completely defined; past studies suggested CDK8 kinase
activity was required for its repressive function. Using a reconstituted transcription
system together with recombinant or endogenous CDK8 subcomplexes, we demonstrate
that, in fact, Med12 and Med13 are critical for subcomplex-dependent repression,
whereas CDK8 kinase activity is not. A hallmark of activated transcription is
efficient reinitiation from promoter-bound scaffold complexes that recruit a series
of pol II enzymes to the gene. Notably, the CDK8 submodule strongly represses
even reinitiation events, suggesting a means to fine tune transcript levels. Structural
and biochemical studies confirm the CDK8 submodule binds the Mediator leg/tail
domain via the Med13 subunit, and this submodule-Mediator association precludes
pol II recruitment. Collectively, these results reveal the CDK8 subcomplex functions
as a simple switch that controls the Mediator-pol II interaction to help regulate
transcription initiation and reinitiation events. As Mediator is generally required
for expression of protein-coding genes, this may reflect a common mechanism by
which activated transcription is shut down in human cells.

text: Behaviours evolve by iterations of natural selection, but we have few insights
into the molecular and neural mechanisms involved. Here we show that some Caenorhabditis
elegans wild strains switch between two foraging behaviours in response to subtle
changes in ambient oxygen. This finely tuned switch is conferred by a naturally
variable hexacoordinated globin, GLB-5. GLB-5 acts with the atypical soluble guanylate
cyclases1,2,3, which are a different type of oxygen binding protein, to tune the
dynamic range of oxygen-sensing neurons close to atmospheric (21%) concentrations.
Calcium imaging indicates that one group of these neurons is activated when oxygen
rises towards 21%, and is inhibited as oxygen drops below 21%. The soluble guanylate
cyclase GCY-35 is required for high oxygen to activate the neurons; GLB-5 provides
inhibitory input when oxygen decreases below 21%. Together, these oxygen binding
proteins tune neuronal and behavioural responses to a narrow oxygen concentration
range close to atmospheric levels. The effect of the glb-5 gene on oxygen sensing
and foraging is modified by the naturally variable neuropeptide receptor npr-1
(refs 4, 5), providing insights into how polygenic variation reshapes neural circuit
function.

text: 'During many cellular processes such as cell division, polarization and motility,
the plasma membrane does not only represent a passive physical barrier, but also
provides a highly dynamic platform for the interplay between lipids, membrane
binding proteins and cytoskeletal elements. Even though many regulators of these
interactions are known, their mutual interdependence appears to be highly complex
and difficult to study in a living cell. Over the past few years, in vitro studies
on membrane-cytoskeleton interactions using biomimetic membranes turned out to
be extremely helpful to get better mechanistic insight into the dynamics of these
processes. In this review, we discuss some of the recent developments using in
vitro assays to dissect the role of the players involved: lipids in the membrane,
proteins binding to membranes and proteins binding to membrane proteins. We also
summarize advantages and disadvantages of supported lipid bilayers as model membrane.'

text: In animal and plant cells, mitotic chromatin locally generates microtubules
that self-organize into a mitotic spindle, and its dimensions and bipolar symmetry
are essential for accurate chromosome segregation. By immobilizing microscopic
chromatin-coated beads on slide surfaces using a microprinting technique, we have
examined the effect of chromatin on the dimensions and symmetry of spindles in
Xenopus laevis cytoplasmic extracts. While circular spots with diameters around
14-18 μm trigger bipolar spindle formation, larger spots generate an incorrect
number of poles. We also examined lines of chromatin with various dimensions.
Their length determined the number of poles that formed, with a 6 × 18 μm rectangular
patch generating normal spindle morphology. Around longer lines, multiple poles
formed and the structures were disorganized. While lines thinner than 10 μm generated
symmetric structures, thicker lines induced the formation of asymmetric structures
where all microtubules are on the same side of the line. Our results show that
chromatin defines spindle shape and orientation. For a video summary of this article,
see the PaperFlick file available with the online Supplemental Data.

text: In Drosophila, there is a consistent deficit of male-biased genes on the X
chromosome. It has been suggested that male-biased genes may evolve from initially
unbiased genes as a result of increased expression levels in males. If transcription
rates are limited, a large increase in expression in the testis may be harder
to achieve for single-copy X-linked genes than for autosomal genes, because they
are already hypertranscribed due to dosage compensation. This hypothesis predicts
that the larger the increase in expression required to make a male-biased gene,
the lower the chance of this being achievable if it is located on the X chromosome.
Consequently, highly expressed male-biased genes should be located on the X chromosome
less often than lowly expressed male-biased genes. This pattern is observed in
our analysis of publicly available data, where microarray data or EST data are
used to detect male-biased genes in D. melanogaster and to measure their expression
levels. This is consistent with the idea that limitations in transcription rates
may prevent male-biased genes from accumulating on the X chromosome.

text: Current models of X-linked and autosomal evolutionary rates often assume that
the effective population size of the X chromosome (NeX) is equal to three-quarters
of the autosomal population size (NeA). However, polymorphism studies of Drosophila
melanogaster and D. simulans suggest that there are often significant deviations
from this value. We have computed fixation rates of beneficial and deleterious
mutations at X-linked and autosomal sites when this occurs. We find that NeX/NeA
is a crucial parameter for the rates of evolution of X-linked sites compared to
autosomal sites. Faster-X evolution due to the fixation of beneficial mutations
can occur under a much wider range of levels of dominance when NeX/N eA > 3/4.
We also examined various parameters that are known to influence the rates of evolution
at X-linked and autosomal sites, such as different mutation rates in males and
females and mutations that are sexually antagonistic, to determine which cases
can lead to faster-X evolution. We show that, when the rate of nonsynonymous evolution
is normalized by the rate of neutral evolution, a sex difference in mutation rate
has no influence on the conditions for faster-X evolution.

text: In many eukaryotic organisms, gender is determined by a pair of heteromorphic
sex chromosomes. Degeneration of the non-recombining Y chromosome is a general
facet of sex chromosome evolution. Selective pressure to restore expression levels
of X-linked genes relative to autosomes accompanies Y-chromosome degeneration,
thus driving the evolution of dosage compensation mechanisms. This review focuses
on evolutionary aspects of dosage compensation, in light of recent advances in
comparative and functional genomics that have substantially increased our understanding
of the molecular mechanisms of dosage compensation and how it evolved. We review
processes involved in sex chromosome evolution, and discuss the dynamic interaction
between Y degeneration and the acquisition of dosage compensation. We compare
mechanisms of dosage compensation and the origin of dosage compensation genes
between different taxa and comment on sex chromosomes that apparently lack compensation
mechanisms. Finally, we discuss how dosage compensation systems can also influence
the evolution of well-established sex chromosomes.

text: One possible way to produce ultra-cold, high-phase-space-density quantum gases
of molecules in the rovibronic ground state is given by molecule association from
quantum-degenerate atomic gases on a Feshbach resonance and subsequent coherent
optical multi-photon transfer into the rovibronic ground state. In ultra-cold
samples of Cs2 molecules, we observe two-photon dark resonances that connect the
intermediate rovibrational level |v=73,J=2 with the rovibrational ground state
|v=0,J=0 of the singlet X 1 ∑ g + ground-state potential. For precise dark resonance
spectroscopy we exploit the fact that it is possible to efficiently populate the
level |v=73,J=2 by two-photon transfer from the dissociation threshold with the
stimulated Raman adiabatic passage (STIRAP) technique. We find that at least one
of the two-photon resonances is sufficiently strong to allow future implementation
of coherent STIRAP transfer of a molecular quantum gas to the rovibrational ground
state |v=0,J=0.

text: Ultracold atomic physics offers myriad possibilities to study strongly correlated
many-body systems in lower dimensions. Typically, only ground-state phases are
accessible. Using a tunable quantum gas of bosonic cesium atoms, we realized and
controlled in one-dimensional geometry a highly excited quantum phase that is
stabilized in the presence of attractive interactions by maintaining and strengthening
quantum correlations across a confinement-induced resonance. We diagnosed the
crossover from repulsive to attractive interactions in terms of the stiffness
and energy of the system. Our results open up the experimental study of metastable,
excited, many-body phases with strong correlations and their dynamical properties.

text: We demonstrate efficient transfer of ultracold molecules into a deeply bound
rovibrational level of the singlet ground state potential in the presence of an
optical lattice. The overall molecule creation efficiency is 25%, and the transfer
efficiency to the rovibrational level |v = 73, J = 2) is above 80%. We find that
the molecules in |v = 73, J = 2) are trapped in the optical lattice, and that
the lifetime in the lattice is limited by optical excitation by the lattice light.
The molecule trapping time for a lattice depth of 15 atomic recoil energies is
about 20 ms. We determine the trapping frequency by the lattice phase and amplitude
modulation technique. It will now be possible to transfer the molecules to the
rovibrational ground state |v = 0, J = 0) in the presence of the optical lattice.

text: One possibility for the creation of ultracold, high phase space density quantum
gases of molecules in the rovibronic ground state relies on first associating
weakly-bound molecules from quantum-degenerate atomic gases on a Feshbach resonance
and then transferring the molecules via several steps of coherent two-photon stimulated
Raman adiabatic passage (STIRAP) into the rovibronic ground state. Here, in ultracold
samples of Cs2 Feshbach molecules produced out of ultracold samples of Cs atoms,
we observe several optical transitions to deeply-bound rovibrational levels of
the excited 0 u+ molecular potentials with high resolution. At least one of these
transitions, although rather weak, allows efficient STIRAP transfer into the deeply-bound
vibrational level v = 73> of the singlet X 1Σg+ ground state potential, as
recently demonstrated (J. G. Danzl, E. Haller, M. Gustavsson, M. J. Mark, R. Hart,
N. Bouloufa, O. Dulieu, H. Ritsch, and H.-C. Nägerl, Science, 2008, 321, 1062).
From this level, the rovibrational ground state v = 0, J = 0> can be reached
with one more transfer step. In total, our results show that coherent ground state
transfer for Cs2 is possible using a maximum of two successive two-photon STIRAP
processes or one single four-photon STIRAP process.
