text: 'Classical models of gene flow fail in three ways: they cannot explain large-scale
patterns; they predict much more genetic diversity than is observed; and they
assume that loosely linked genetic loci evolve independently. We propose a new
model that deals with these problems. Extinction events kill some fraction of
individuals in a region. These are replaced by offspring from a small number of
parents, drawn from the preexisting population. This model of evolution forwards
in time corresponds to a backwards model, in which ancestral lineages jump to
a new location if they are hit by an event, and may coalesce with other lineages
that are hit by the same event. We derive an expression for the identity in allelic
state, and show that, over scales much larger than the largest event, this converges
to the classical value derived by Wright and Malécot. However, rare events that
cover large areas cause low genetic diversity, large-scale patterns, and correlations
in ancestry between unlinked loci.'

text: 'Streaming string transducers [1] define (partial) functions from input strings
to output strings. A streaming string transducer makes a single pass through the
input string and uses a finite set of variables that range over strings from the
output alphabet. At every step, the transducer processes an input symbol, and
updates all the variables in parallel using assignments whose right-hand-sides
are concatenations of output symbols and variables with the restriction that a
variable can be used at most once in a right-hand-side expression. It has been
shown that streaming string transducers operating on strings over infinite data
domains are of interest in algorithmic verification of list-processing programs,
as they lead to PSPACE decision procedures for checking pre/post conditions and
for checking semantic equivalence, for a well-defined class of heap-manipulating
programs. In order to understand the theoretical expressiveness of streaming transducers,
we focus on streaming transducers processing strings over finite alphabets, given
the existence of a robust and well-studied class of "regular" transductions
for this case. Such regular transductions can be defined either by two-way deterministic
finite-state transducers, or using a logical MSO-based characterization. Our main
result is that the expressiveness of streaming string transducers coincides exactly
with this class of regular transductions. '

text: 'Graph games of infinite length are a natural model for open reactive processes:
one player represents the controller, trying to ensure a given specification,
and the other represents a hostile environment. The evolution of the system depends
on the decisions of both players, supplemented by chance. In this work, we focus
on the notion of randomised strategy. More specifically, we show that three natural
definitions may lead to very different results: in the most general cases, an
almost-surely winning situation may become almost-surely losing if the player
is only allowed to use a weaker notion of strategy. In more reasonable settings,
translations exist, but they require infinite memory, even in simple cases. Finally,
some traditional problems becomes undecidable for the strongest type of strategies.'

text: Any programming error that can be revealed before compiling a program saves
precious time for the programmer. While integrated development environments already
do a good job by detecting, e.g., data-flow abnormalities, current static analysis
tools suffer from false positives ("noise") or require strong user interaction.
We propose to avoid this deficiency by defining a new class of errors. A program
fragment is doomed if its execution will inevitably fail, regardless of which
state it is started in. We use a formal verification method to identify such errors
fully automatically and, most significantly, without producing noise. We report
on experiments with a prototype tool.

text: 'We investigate the transferability of an enhanced temperature-index melt
model that was developed and tested on Haut Glacier d’Arolla, Switzerland, in
the 2001 season. The model’s empirical parameters (temperature factor, TF, and
shortwave radiation factor, SRF) are recalibrated for: (1) other locations on
Haut Glacier d’Arolla; (2) subperiods of distinct meteorological conditions; (3)
different years on Haut Glacier d’Arolla; and (4) other glaciers in different
years. The model parameters are optimized against simulations of an energy-balance
model validated against ablation observations. Results are compared with those
obtained with the original parameters. The model works very well when applied
to other sites, seasons and glaciers, with the exception of overcast conditions.
Differences are due to underestimation of high melt rates. The parameter values
are associated with the prevailing energy-balance conditions, showing that high
SRF are obtained on clear-sky days, whereas higher TF are typical of locations
where glacier winds prevail and turbulent fluxes are high. We also provide a range
of parameters clearly associated with the site’s location and its meteorological
characteristics that could help to assign parameter values to sites where few
data are available.'

text: We discuss the inclusion of the subsurface heat-conduction flux into the calculation
of the energy balance and ablation at the glacier–atmosphere interface. Data from
automatic weather stations are used to force an energy-balance model at several
locations on alpine glaciers and at one site in the dry Andes of central Chile.
The heat-conduction flux is computed using a two-layer scheme, assuming that 36%
of the net shortwave radiation is absorbed by the surface layer and that the rest
penetrates into the snowpack. We compare simulations conducted with and without
subsurface heat flux. Results show that assuming a surface temperature of zero
degrees leads to a larger overestimation of melt at the sites in the accumulation
area (10.4–13.3%) than in the ablation area (0.5–2.8%), due to lower air temperatures
and the presence of snow. The difference between simulations with and without
heat conduction is also high at the beginning and end of the ablation season (up
to 29% for the first 15 days of the season), when air temperatures are lower and
snow covers the glacier surface, while they are of little importance during periods
of sustained melt at all the locations investigated.

text: 'The nervous system of seeing animals derives information about optic flow
in two subsequent steps. First, local motion vectors are calculated from moving
retinal images, and second, the spatial distribution of these vectors is analyzed
on the dendrites of large downstream neurons. In dipteran flies, this second step
relies on a set of motion-sensitive lobula plate tangential cells (LPTCs), which
have been studied in great detail in large fly species. Yet, studies on neurons
that convey information to LPTCs and neuroanatomical investigations that enable
a mechanistic understanding of the underlying dendritic computations in LPTCs
are rare. We investigated the subcellular distribution of nicotinic acetylcholine
receptors (nAChRs) on two sets of LPTCs: vertical system (VS) and horizontal system
(HS) cells in Drosophila melanogaster. In this paper, we describe that both cell
types express Dα7-type nAChR subunits specifically on higher order dendritic branches,
similar to the expression of gamma aminobutyric acid (GABA) receptors. These findings
support a model in which directional selectivity of LPTCs is achieved by the dendritic
integration of excitatory, cholinergic, and inhibitory GABA-ergic input from local
motion detectors with opposite preferred direction. Nonetheless, whole-cell recordings
in mutant flies without Dα7 nAChRs revealed that direction selectivity of VS and
HS cells is largely retained. In addition, mutant LPTCs were responsive to acetylcholine
and remaining nAChR receptors were labeled by α-bungarotoxin. These results in
LPTCs with genetically manipulated excitatory input synapses suggest a robust
cellular implementation of dendritic processing that warrants direction selectivity.
The underlying mechanism that ensures appropriate nAChR-mediated synaptic currents
and the functional implications of separate sets or heteromultimeric nAChRs can
now be addressed in this system.'

text: Hydrogen bonds are ubiquitous interactions in proteins, and are important
for their folding and functionality. Scalar coupling constants across hydrogen
bonds in the protein backbone, some as small as 0.5 Hz, can be directly measured
in the solid state by NMR spectroscopy (see figure). The nuclei on both sides
of the hydrogen bond can be identified and the size of the coupling constant can
be measured accurately.

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.

can be used for the generation of energetic ions. To demonstrate this potential,
a terawatt Ti: Al2 O3 laser focused to 2×10 19 W/cm2 was used to irradiate heavy
water (D2 O) aerosols composed of micron-scale droplets. Energetic deuterium ions,

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.

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: 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.
