text: Side-chain poly[2]catenanes at the click of a switch! A bistable side-chain
poly[2]catenane has been synthesized and found to form hierarchical self-assembled
hollow superstructures of nanoscale dimensions in solution. Molecular electromechanical
switching (see picture) of the material is demonstrated, and the ground-state
equilibrium thermodynamics and switching kinetics are examined as the initial
steps towards processible molecular-based electronic devices and nanoelectromechanical
systems.

text: We consider probabilistic automata on infinite words with acceptance defined
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: '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.'

abstract:
- lang: eng
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: 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,

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.

text: Parent-of-origin-specific (imprinted) gene expression is regulated in Arabidopsis
thaliana endosperm by cytosine demethylation of the maternal genome mediated by
the DNA glycosylase DEMETER, but the extent of the methylation changes is not
known. Here, we show that virtually the entire endosperm genome is demethylated,
coupled with extensive local non-CG hypermethylation of small interfering RNA–targeted
sequences. Mutation of DEMETER partially restores endosperm CG methylation to
levels found in other tissues, indicating that CG demethylation is specific to
maternal sequences. Endosperm demethylation is accompanied by CHH hypermethylation
of embryo transposable elements. Our findings demonstrate extensive reconfiguration
of the endosperm methylation landscape that likely reinforces transposon silencing
in the embryo.

text: A theory of the fluctuation-induced Nernst efl'ect is developed for a two-dimensional
superconductor in a perpendicular magnetic field. First, we derive a simple phenomenological
formula for the Nernst coefficient, which naturally explains the giant Nernst
signal due to fluctuating Cooper pairs. The latter signal is shown to be large
even far from the transition and may exceed by orders of magnitude the Fermi liquid
terms. We also present a complete microscopic calculation of the Nernst coefficient
for arbitrary magnetic fields and temperatures, which is based on the standard
definition of heat current vertices. It is shown that the magnitude and the behavior
of the Nernst signal observed experimentally in disordered superconducting films
can be well understood on the basis of superconducting fluctuation theory.

text: In order to better understand magnetic reconnection and particle acceleration
in solar flares, we compare the RHESSI hard X-ray (HXR) footpoint motions of three
flares with a detailed study of the corresponding topology given by a Magnetic
Charge Topology model. We analyze the relationship between the footpoint motions
and topological spine lines and find that the examined footpoint sources move
along spine lines. We present a three-dimensional topological model in which this
movement can be understood. As reconnection proceeds, flux is transferred between
the reconnecting domains, causing the separator to move. The movement of the separator\'s
chromospheric ends, identified with the HXR footpoints, is along those spine lines
on which the separator ends.

text: Thin streams of liquid commonly break up into characteristic droplet patterns
owing to the surface-tension-driven PlateauRayleigh instability 1-3. Very similar
patterns are observed when initially uniform streams of dry granular material
break up into clusters of grains4-6, even though flows of macroscopic particles
are considered to lack surface tension7,8. Recent studies on freely falling granular
streams tracked fluctuations in the stream profile9, but the clustering mechanism
remained unresolved because the full evolution of the instability could not be
observed. Here we demonstrate that the cluster formation is driven by minute,
nanoNewton cohesive forces that arise from a combination of van der Waals interactions
and capillary bridges between nanometre-scale surface asperities. Our experiments
involve high-speed video imaging of the granular stream in the co-moving frame,
control over the properties of the grain surfaces and the use of atomic force
microscopy to measure grain-grain interactions. The cohesive forces that we measure
correspond to an equivalent surface tension five orders of magnitude below that,
of ordinary liquids. We find that, the shapes of these weakly cohesive, non-thermal
clusters of macroscopic particles closely resemble droplets resulting from thermally
induced rupture of liquid nanojets 10-12.

text: Over the last decade, the nuclear envelope (NE) has emerged as a key component
in the organization and function of the nuclear genome. As many as 100 different
proteins are thought to specifically localize to this double membrane that separates
the cytoplasm and the nucleoplasm of eukaryotic cells. Selective portals through
the NE are formed at sites where the inner and outer nuclear membranes are fused,
and the coincident assembly of ∼30 proteins into nuclear pore complexes occurs.
These nuclear pore complexes are essential for the control of nucleocytoplasmic
exchange. Many of the NE and nuclear pore proteins are thought to play crucial
roles in gene regulation and thus are increasingly linked to human diseases.

text: Nuclear-pore complexes (NPCs) are large protein channels that span the nuclear
envelope (NE), which is a double membrane that encloses the nuclear genome of
eukaryotes. Each of the typically 2,000–4,000 pores in the NE of vertebrate cells
is composed of multiple copies of 30 different proteins known as nucleoporins.
The evolutionarily conserved NPC proteins have the well-characterized function
of mediating the transport of molecules between the nucleoplasm and the cytoplasm.
Mutations in nucleoporins are often linked to specific developmental defects and
disease, and the resulting phenotypes are usually interpreted as the consequences
of perturbed nuclear transport activity. However, recent evidence suggests that
NPCs have additional functions in chromatin organization and gene regulation,
some of which might be independent of nuclear transport. Here, we review the transport-dependent
and transport-independent roles of NPCs in the regulation of nuclear function
and gene expression.

text: Formation of the nuclear envelope (NE) around segregated chromosomes occurs
by the reshaping of the endoplasmic reticulum (ER), a reservoir for disassembled
nuclear membrane components during mitosis. In this study, we show that inner
nuclear membrane proteins such as lamin B receptor (LBR), MAN1, Lap2β, and the
trans-membrane nucleoporins Ndc1 and POM121 drive the spreading of ER membranes
into the emerging NE via their capacity to bind chromatin in a collaborative manner.
Despite their redundant functions, decreasing the levels of any of these trans-membrane
proteins by RNAi-mediated knockdown delayed NE formation, whereas increasing the
levels of any of them had the opposite effect. Furthermore, acceleration of NE
formation interferes with chromosome separation during mitosis, indicating that
the time frame over which chromatin becomes membrane enclosed is physiologically
relevant and regulated. These data suggest that functionally distinct classes
of chromatin-interacting membrane proteins, which are present at nonsaturating
levels, collaborate to rapidly reestablish the nuclear compartment at the end
of mitosis.

text: Nucleocytoplasmic transport occurs exclusively through nuclear pore complexes
(NPCs) embedded in pores formed by inner and outer nuclear membrane fusion. The
mechanism for de novo pore and NPC biogenesis remains unclear. Reticulons (RTNs)
and Yop1/DP1 are conserved membrane protein families required to form and maintain
the tubular endoplasmic reticulum (ER) and the postmitotic nuclear envelope. In
this study, we report that members of the RTN and Yop1/DP1 families are required
for nuclear pore formation. Analysis of Saccharomyces cerevisiae prp20-G282S and
nup133Δ NPC assembly mutants revealed perturbations in Rtn1–green fluorescent
protein (GFP) and Yop1-GFP ER distribution and colocalization to NPC clusters.
Combined deletion of RTN1 and YOP1 resulted in NPC clustering, nuclear import
defects, and synthetic lethality with the additional absence of Pom34, Pom152,
and Nup84 subcomplex members. We tested for a direct role in NPC biogenesis using
Xenopus laevis in vitro assays and found that anti-Rtn4a antibodies specifically
inhibited de novo nuclear pore formation. We hypothesize that these ER membrane–bending
proteins mediate early NPC assembly steps.
