text: Atomic-resolution information on the structure and dynamics of nucleic acids
is essential for a better understanding of the mechanistic basis of many cellular
processes. NMR spectroscopy is a powerful method for studying the structure and
dynamics of nucleic acids; however, solution NMR studies are currently limited
to relatively small nucleic acids at high concentrations. Thus, technological
and methodological improvements that increase the experimental sensitivity and
spectral resolution of NMR spectroscopy are required for studies of larger nucleic
acids or protein−nucleic acid complexes. Here we introduce a series of imino-proton-detected
NMR experiments that yield an over 2-fold increase in sensitivity compared to
conventional pulse schemes. These methods can be applied to the detection of base
pair interactions, RNA−ligand titration experiments, measurement of residual dipolar
15N−1H couplings, and direct measurements of conformational transitions. These
NMR experiments employ longitudinal spin relaxation enhancement techniques that
have proven useful in protein NMR spectroscopy. The performance of these new experiments
is demonstrated for a 10 kDa TAR-TAR*GA RNA kissing complex and a 26 kDa tRNA.

text: Allosteric regulation is an effective mechanism of control in biological processes.
In allosteric proteins a signal originating at one site in the molecule is communicated
through the protein structure to trigger a specific response at a remote site.
Using NMR relaxation dispersion techniques we directly observe the dynamic process
through which the KIX domain of CREB binding protein communicates allosteric information
between binding sites. KIX mediates cooperativity between pairs of transcription
factors through binding to two distinct interaction surfaces in an allosteric
manner. We show that binding the activation domain of the mixed lineage leukemia
(MLL) transcription factor to KIX induces a redistribution of the relative populations
of KIX conformations toward a high-energy state in which the allosterically activated
second binding site is already preformed, consistent with the Monod−Wyman−Changeux
(WMC) model of allostery. The structural rearrangement process that links the
two conformers and by which allosteric information is communicated occurs with
a time constant of 3 ms at 27 °C. Our dynamic NMR data reveal that an evolutionarily
conserved network of hydrophobic amino acids constitutes the pathway through which
information is transmitted.

text: Multidimensional NMR spectroscopy is a well-established technique for the
characterization of structure and fast-time-scale dynamics of highly populated
ground states of biological macromolecules. The investigation of short-lived excited
states that are important for molecular folding, misfolding and function, however,
remains a challenge for modern biomolecular NMR techniques. Off-equilibrium real-time
kinetic NMR methods allow direct observation of conformational or chemical changes
by following peak positions and intensities in a series of spectra recorded during
a kinetic event. Because standard multidimensional NMR methods required to yield
sufficient atom-resolution are intrinsically time-consuming, many interesting
phenomena are excluded from real-time NMR analysis. Recently, spatially encoded
ultrafast 2D NMR techniques have been proposed that allow one to acquire a 2D
NMR experiment within a single transient. In addition, when combined with the
SOFAST technique, such ultrafast experiments can be repeated at high rates. One
of the problems detected for such ultrafast protein NMR experiments is related
to the heteronuclear decoupling during detection with interferences between the
pulses and the oscillatory magnetic field gradients arising in this scheme. Here
we present a method for improved ultrafast data acquisition yielding higher signal
to noise and sharper lines in single-scan 2D NMR spectra. In combination with
a fast-mixing device, the recording of 1H–15N correlation spectra with repetition
rates of up to a few Hertz becomes feasible, enabling real-time studies of protein
kinetics occurring on time scales down to a few seconds.

text: We study generic unfoldings of homoclinic tangencies of two-dimensional area-preserving
diffeomorphisms (conservative New house phenomena) and show that they give rise
to invariant hyperbolic sets of arbitrarily large Hausdorff dimension. As applications,
we discuss the size of the stochastic layer of a standard map and the Hausdorff
dimension of invariant hyperbolic sets for certain restricted three-body problems.
We avoid involved technical details and only concentrate on the ideas of the proof
of the presented results.

text: Although some data link archaeal and eukaryotic translation, the overall mechanism
of protein synthesis in archaea remains largely obscure. Both archaeal (aRF1)
and eukaryotic (eRF1) single release factors recognize all three stop codons.
The archaeal genus Methanosarcinaceae contains two aRF1 homologs, and also uses
the UAG stop to encode the 22nd amino acid, pyrrolysine. Here we provide an analysis
of the last stage of archaeal translation in pyrrolysine-utilizing species. We
demonstrated that only one of two Methanosarcina barkeri aRF1 homologs possesses
activity and recognizes all three stop codons. The second aRF1 homolog may have
another unknown function. The mechanism of pyrrolysine incorporation in the Methanosarcinaceae
is discussed.
acknowledgement: We are grateful to Andrey Poltaraus and his colleagues for sequencing
a/eRF1 genes. We thank Tatyana Pestova and Chris Hellen for the gift of plasmids

text: As part of an ongoing effort to develop a parameterization of wave-induced
abyssal mixing, the authors derive an heuristic model for nonlinear wave breaking
and energy dissipation associated with internal tides. Then the saturation and
dissipation of internal tides for idealized and observed topography samples are
investigated. One of the main results is that the wave-induced mixing could be
more intense and more confined to the bottom than previously assumed in numerical
models. Furthermore, in this model wave breaking and mixing clearly depend on
the small scales of the topography below 10 km or so, which is below the current
resolution of global bathymetry. This motivates the use of a statistical approach
to represent the unresolved topography when addressing the role of internal tides
in mixing the deep ocean.

text: Several observational studies have shown a tight relationship between tropical
precipitation and column‐integrated water vapor. We show that the observed relationship
in the tropics between column‐integrated water vapor, precipitation, and its variance
can be qualitatively reproduced by a simple and physically motivated two‐layer
model. It has previously been argued that features of this relationship could
be explained by analogy with the theory of continuous phase transitions. Instead,
our model explicitly assumes that the onset of precipitation is governed by a
stability threshold involving boundary‐layer water vapor. This allows us to explain
the precipitation‐humidity relationship over a broader range of water vapor values,
and may explain the observed temperature dependence of the relationship.

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: 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: We show evidence that a structural martensitic transition is related to significant
changes in the electronic structure, as revealed in thermodynamic measurements
made in high magnetic fields. The effect of the magnetic field is considered unusual
as many influential investigations of martensitic transitions have emphasized
that the structural transitions are primarily lattice dynamical and are driven
by the entropy due to the phonons. We provide a theoretical framework, which can
be used to describe the effect of the magnetic field on the lattice dynamics in
which the field dependence originates from the dielectric constant.

text: In the first paper of this series, an experimental technique for measuring
the current-density distribution with a resolution better than the sub-millimeter
scale of the channel and rib structures in the flow-field plates of polymer electrolyte
fuel cells (PEFCs) was introduced. This method is extended to the determination
of local membrane resistance with the same spatial resolution in the present paper.
The combined measurement of current and resistance allows for investigating the
interaction of mass- and charge-transport processes, which determine the local
rate distribution across the domain of channels and ribs. Therewith, the influence
of relevant operating parameters such as reactant composition, dew points, and
cell compression on local current generation is investigated. The results show
that the distribution of water and oxidant across the channel and rib are the
main reasons for significant current gradients on a scale smaller than a millimeter.
Humidity variation mainly affects the membrane resistance under the channel, while
reactant concentration predominantly influences current generation under the rib-covered
cell area.
