text: We consider concurrent two-person games played in real time, in which the
players decide both which action to play, and when to play it. Such timed games
differ from untimed games in two essential ways. First, players can take each
other by surprise, because actions are played with delays that cannot be anticipated
by the opponent. Second, a player should not be able to win the game by preventing
time from diverging. We present a model of timed games that preserves the element
of surprise and accounts for time divergence in a way that treats both players
symmetrically and applies to all ω-regular winning conditions. We prove that the
ability to take each other by surprise adds extra power to the players. For the
case that the games are specified in the style of timed automata, we provide symbolic
algorithms for their solution with respect to all ω-regular winning conditions.
We also show that for these timed games, memory strategies are more powerful than
memoryless strategies already in the case of reachability objectives.

text: "For many years considerable efforts have been put into investigating and
modelling hydrological processes of mountainous catchments. On the one hand, the
complexity and intrinsically high variability of the involved processes as well
as insufficient knowledge of the underlying physical mechanisms still induce large
uncertainties in understanding observed phenomena and predicting the behaviour
of the system. On the other hand, the demand for models that are able to simulate
mountainous water resource systems is increasing because of the needs related
to both water exploitation and water conservation, which clearly call for an integrated
vision and modelling of these systems.\r\nAccordingly, this paper moves from a
brief survey of the most significant achievements in mountain hydrology to discuss
what could be future challenging issues related to the broader spectrum of questions,
which hydrologic modelling of mountainous river systems may face in the next decades.
Firstly, reference is made to existing methodologies for modelling alpine water
systems, focussing on some specific aspects that provide a basis for the discussion
of the weaknesses and perspectives of present simulation tools. The future is
thus discussed, delineating some of the research challenges that may foster a
comprehensive and integrated vision of water related issues in mountainous regions."

text: The polymeric ubiquitin (poly-u) genes are composed of tandem 228-bp repeats
with no spacer sequences between individual monomer units. Ubiquitin is one of
the most conserved proteins known to date, and the individual units within a number
of poly-u genes are significantly more similar to each other than would be expected
if each unit evolved independently. It has been proposed that the rather striking
similarity among poly-u monomers in some lineages is caused by a series of homogenization
events. Here we report the sequences of the polyubiquitin-C (Ubc) genes in two
mouse strains. Analysis of these sequences, as well as those of the previously
reported Chinese hamster and rat poly-u genes, supports the assertion that the
homogenization of the ubiquitin-C gene in rodents is due to unequal crossing-over
events. The sequence divergence of noncoding DNA was used to estimate the frequency
of unequal crossing-over events (6.3 x 10-5 events per generation) in the Ubc
gene, as well as to provide evidence of apparent selection in the poly-u gene.

text: 'BACKGROUND: Gene duplications have a major role in the evolution of new biological
functions. Theoretical studies often assume that a duplication per se is selectively
neutral and that, following a duplication, one of the gene copies is freed from
purifying (stabilizing) selection, which creates the potential for evolution of
a new function. RESULTS: In search of systematic evidence of accelerated evolution
after duplication, we used data from 26 bacterial, six archaeal, and seven eukaryotic
genomes to compare the mode and strength of selection acting on recently duplicated
genes (paralogs) and on similarly diverged, unduplicated orthologous genes in
different species. We find that the ratio of nonsynonymous to synonymous substitutions
(Kn/Ks) in most paralogous pairs is <<1 and that paralogs typically evolve
at similar rates, without significant asymmetry, indicating that both paralogs
produced by a duplication are subject to purifying selection. This selection is,
however, substantially weaker than the purifying selection affecting unduplicated
orthologs that have diverged to the same extent as the analyzed paralogs. Most
of the recently duplicated genes appear to be involved in various forms of environmental
response; in particular, many of them encode membrane and secreted proteins. CONCLUSIONS:
The results of this analysis indicate that recently duplicated paralogs evolve
faster than orthologs with the same level of divergence and similar functions,
but apparently do not experience a phase of neutral evolution. We hypothesize
that gene duplications that persist in an evolving lineage are beneficial from
the time of their origin, due primarily to a protein dosage effect in response
to variable environmental conditions; duplications are likely to give rise to
new functions at a later phase of their evolution once a higher level of divergence
is reached.'

text: We study fitness landscape in the space of protein sequences by relating sets
of human pathogenic missense mutations in 32 proteins to amino acid substitutions
that occurred in the course of evolution of these proteins. On average, ≈10% of
deviations of a nonhuman protein from its human ortholog are compensated pathogenic
deviations (CPDs), i.e., are caused by an amino acid substitution that, at this
site, would be pathogenic to humans. Normal functioning of a CPD-containing protein
must be caused by other, compensatory deviations of the nonhuman species from
humans. Together, a CPD and the corresponding compensatory deviation form a Dobzhansky-Muller
incompatibility that can be visualized as the corner on a fitness ridge. Thus,
proteins evolve along fitness ridges which contain only ≈10 steps between sucessive
corners. The fraction of CPDs among all deviations of a protein from its human
ortholog does not increase with the evolutionary distance between the proteins,
indicating that subtitutions that carry evolving proteins around these corners
occur in rapid succession, driven by positive selection. Data on fitness of interspecies
hybrids suggest that the compensatory change that makes a CPD fit usually occurs
within the same protein. Data on protein structures and on cooccurrence of amino
acids at different sites of multiple orthologous proteins often make it possible
to provisionally identify the substitution that compensates a partiCUlar CPD.

text: "Transcription is a slow and expensive process: in eukaryotes, approximately
20 nucleotides can be transcribed per second at the expense of at least two ATP
molecules per nucleotide. Thus, at least for highly expressed genes, transcription
of long introns, which are particularly common in mammals, is costly. Using data
on the expression of genes that encode proteins in Caenorhabditis elegans and
Homo sapiens, we show that introns in highly expressed genes are substantially
shorter than those in genes that are expressed at low levels. This difference
is greater in humans, such that introns are, on average, 14 times shorter in highly
expressed genes than in genes with low expression, whereas in C. Elegans the difference
in intron length is only twofold. In contrast, the density of introns in a gene
does not strongly depend on the level of gene expression. Thus, natural selection
appears to favor short introns in highly expressed genes to minimize the cost
of transcription and other molecular processes, such as splicing.\r\n"

text: A new solvent-free composite polymer electrolyte consisting of high-molecular
mass polyethylene oxide (PEO) filled with titanium oxide and containing LiI and
I2 was developed. The introduction of the inorganic filler (TiO2 Degussa P25)
into the polymer matrix produces dramatic morphological changes to the host polymer
structure. Upon addition of the inorganic oxide, the surface roughness increases,
with respect to the original polymer and in parallel, the fractal dimension decreases.
Both the thermograms and the atomic force microscope (AFM) pictures confirm the
amorphicity of the composite electrolyte. The polymer sub-units are held together
in a parallel orientation, forming straight long chains of about 500 nm in width,
along which TiO2 spherical particles of about 20-25 nm in diameter are distributed.
The polymer chains separated by the titania particles are arranged in a three-dimensional,
mechanically stable network, that creates free space and voids into which the
iodide/triodide anions can easily migrate. All solid-state dye-sensitized solar
cells fabricated using this composite electrolyte present high efficiencies (typical
maximum incident photon to current efficiency (IPCE) as high as 40% at 520 nm
and overall conversion efficiency (η) of 0.96% (Voc = 0.67 V, Jsc = 2.050 mA/cm2,
FF = 39%) under direct solar irradiation. Further improvement of the photovoltaic
performance is expected by optimization of the electrolyte parameters and of the
cell assembly.

text: New dyes of the type Ru(II)(bdmpp)(bpy) [where bdmpp is 2,6-bis(3,5-dimethyl-N-pyrazoyl)pyridine
and bpy is 2,2′-bipyridine-4,4′-dicarboxylic acid] are prepared and characterized
by infra-red (IR), mass (MS) and electrospray mass spectroscopy (ES-MS) as well
as 1H NMR (1D and 2D) spectroscopies. The compounds present broad and very high
intensity MLCT absorption bands in the visible and can be chemically anchored
on TiO2 films via ester-like linkage involving carboxylato groups. These complexes
have been tested with success as potential molecular antennas in dye-sensitized
solar cells. Both opaque and transparent nanocrystalline TiO2 thin film electrodes
obtained by a doctor blade technique sensitized by these complexes were incorporated
in a sandwich type regenerative photoelectrochemical solar cell containing 0.1M
LiI +0.01M I2 in propylene carbonate as well as a platinized conductive glass
counter electrode. The cell was characterized by Raman spectroscopy under anodic
and cathodic bias. Two new vibration bands were observed in the lower frequency
region. The first one at 112 cm-1 is due to tri-iodide formed on the photoactive
electrode, and the second one at 167 cm-1 is a sign of the dye/iodide interaction
and corresponds to a vibration in a chemically stable "DI" intermediate
species. Under direct sunlight illumination (solar irradiance of 60 mW/cm2) by
using a composite polymer solid state electrolyte, the cell ITO/TiO2/[Ru(II)(bdmpp)(bpy)(NCS)](PF6)/electrolyte/Pt-ITO
produced a continuous photocurrent as high as 4.29mA/cm2, and gave IPCE values
about half of the corresponding values obtained by the standard N3 dye under the
same conditions. The photovoltage is about 600 mV and the overall energy conversion
cell's efficiency is as high as 1.72%.

text: Poly(ethylene oxide)/titania polymer electrolyte based photoelectrochemical
cells have been fabricated with Ru(dcbpy)2(NCS)2 complex as the sensitizer and
nanoporous TiO2 films as photoanodes. The introduction of the titania filler into
the poly(ethylene oxide) matrix reduces the crystallinity of the polymer and enhances
the mobility of the 1-/13 - redox couple, resulting in outstanding overall conversion
efficiency (4.2% under direct sunlight illumination) of the corresponding dye-sensitized
nanocrystalline TiO2 solar cell, one of the best efficiencies reported to date
for a solid-state device.

text: ICln is an ion channel identified by expression cloning using a cDNA library
from Madin-Darby canine kidney cells. In all organisms tested so far, only one
transcript for the ICln protein could be identified. Here we show that two splice
variants of the ICln ion channel can be found in Caenorhabditis elegans. Moreover,
we show that these two splice variants of the ICln channel protein, which we termed
IClnN1 and IClnN2, can be functionally reconstituted and tested in an artificial
lipid bilayer. In these experiments, the IClnN1-induced currents showed no voltage-dependent
inactivation, whereas the IClnN2-induced currents fully inactivated at positive
potentials. The molecular entity responsible for the voltage-dependent inactivation
of IClnN2 is a cluster of positively charged amino acids encoded by exon 2a, which
is absent in IClnN1. Our experiments suggest a mechanism of channel inactivation
that is similar to the “ball and chain” model proposed for the Shaker potassium
channel,i.e. a cluster of positively charged amino acids hinders ion permeation
through the channel by a molecular and voltage-dependent interaction at the inner
vestibulum of the pore. This hypothesis is supported by the finding that synthetic
peptides with the same amino acid sequence as the positive cluster can transform
the IClnN1-induced current to the current observed after reconstitution of IClnN2.
Furthermore, we show that the nematode ICln gene is embedded in an operon harboring
two additional genes, which we termed Nx and Ny. Co-reconstitution of Nx and IClnN2
and functional analysis of the related currents revealed a functional interaction
between the two proteins, as evidenced by the fact that the IClnN2-induced current
in the presence of Nx was no longer voltage-sensitive. The experiments described
indicate that the genome organization in nematodes allows an effective approach
for the identification of functional partner proteins of ion channels.

text: Extending work of Bielawski-Dancer 3 and Konno 14, we develop a theory of
toric hyperkähler varieties, which involves toric geometry, matroid theory and
convex polyhedra. The framework is a detailed study of semi-projective toric varieties,
meaning GIT quotients of affine spaces by torus actions, and specifically, of
Lawrence toric varieties, meaning GIT quotients of even-dimensional affine spaces
by symplectic torus actions. A toric hyperkähler variety is a complete intersection
in a Lawrence toric variety. Both varieties are non-compact, and they share the
same cohomology ring, namely, the Stanley-Reisner ring of a matroid modulo a linear
system of parameters. Familiar applications of toric geometry to combinatorics,
including the Hard Lefschetz Theorem and the volume polynomials of Khovanskii-Pukhlikov
11, are extended to the hyperkähler setting. When the matroid is graphic, our
construction gives the toric quiver varieties, in the sense of Nakajima 17.

text: Wild isolates of Caenorhabditis elegans can feed either alone or in groups1,2.
This natural variation in behaviour is associated with a single residue difference
in NPR-1, a predicted G-protein-coupled neuropeptide receptor related to Neuropeptide
Y receptors2. Here we show that the NPR-1 isoform associated with solitary feeding
acts in neurons exposed to the body fluid to inhibit social feeding. Furthermore,
suppressing the activity of these neurons, called AQR, PQR and URX, using an activated
K+ channel, inhibits social feeding. NPR-1 activity in AQR, PQR and URX neurons
seems to suppress social feeding by antagonizing signalling through a cyclic GMP-gated
ion channel encoded by tax-2 and tax-4. We show that mutations in tax-2 or tax-4
disrupt social feeding, and that tax-4 is required in several neurons for social
feeding, including one or more of AQR, PQR and URX. The AQR, PQR and URX neurons
are unusual in C. elegans because they are directly exposed to the pseudocoelomic
body fluid3. Our data suggest a model in which these neurons integrate antagonistic
signals to control the choice between social and solitary feeding behaviour.

text: 'Natural Caenorhabditis elegans isolates exhibit either social or solitary
feeding on bacteria. We show here that social feeding is induced by nociceptive
neurons that detect adverse or stressful conditions. Ablation of the nociceptive
neurons ASH and ADL transforms social animals into solitary feeders. Social feeding
is probably due to the sensation of noxious chemicals by ASH and ADL neurons;
it requires the genes ocr-2 and osm-9, which encode TRP-related transduction channels,
and odr-4 and odr-8, which are required to localize sensory chemoreceptors to
cilia. Other sensory neurons may suppress social feeding, as social feeding in
ocr-2 and odr-4 mutants is restored by mutations in osm-3, a gene required for
the development of 26 ciliated sensory neurons. Our data suggest a model for regulation
of social feeding by opposing sensory inputs: aversive inputs to nociceptive neurons
promote social feeding, whereas antagonistic inputs from neurons that express
osm-3 inhibit aggregation.'

text: The small GTPase Ran is a key regulator of nucleocytoplasmic transport during
interphase. The asymmetric distribution of the GTP-bound form of Ran across the
nuclear envelope — that is, large quantities in the nucleus compared with small
quantities in the cytoplasm — determines the directionality of many nuclear transport
processes. Recent findings that Ran also functions in spindle formation and nuclear
envelope assembly during mitosis suggest that Ran has a general role in chromatin-centred
processes. Ran functions in these events as a signal for chromosome position.

text: Ran GTPase plays important roles in nucleocytoplasmic transport in interphase
[1, 2] and in both spindle formation and nuclear envelope (NE) assembly during
mitosis [3, 4, 5]. The latter functions rely on the presence of high local concentrations
of GTP-bound Ran near mitotic chromatin [3, 4, 5]. RanGTP localization has been
proposed to result from the association of Ran's GDP/GTP exchange factor, RCC1,
with chromatin [6, 7, 8, 9], but Ran is shown here to bind directly to chromatin
in two modes, either dependent or independent of RCC1, and, where bound, to increase
the affinity of chromatin for NE membranes. We propose that the Ran binding capacity
of chromatin contributes to localized spindle and NE assembly.

text: Now that the low temperature properties of quantum-mechanical many-body systems
(bosons) at low density, ρ, can be examined experimentally it is appropriate to
revisit some of the formulas deduced by many authors 4-5 decades ago. For systems
with repulsive (i.e. positive) interaction potentials the experimental low temperature
state and the ground state are effectively synonymous -- and this fact is used
in all modeling. In such cases, the leading term in the energy/particle is 2πℏ2aρ/m
where a is the scattering length of the two-body potential. Owing to the delicate
and peculiar nature of bosonic correlations (such as the strange N7/5 law for
charged bosons), four decades of research failed to establish this plausible formula
rigorously. The only previous lower bound for the energy was found by Dyson in
1957, but it was 14 times too small. The correct asymptotic formula has recently
been obtained by us and this work will be presented. The reason behind the mathematical
difficulties will be emphasized. A different formula, postulated as late as 1971
by Schick, holds in two-dimensions and this, too, will be shown to be correct.
With the aid of the methodology developed to prove the lower bound for the homogeneous
gas, two other problems have been successfully addressed. One is the proof by
us that the Gross-Pitaevskii equation correctly describes the ground state in
the `traps' actually used in the experiments. For this system it is also possible
to prove complete Bose condensation, as we have shown. Another topic is a proof
that Foldy's 1961 theory of a high density Bose gas of charged particles correctly
describes its ground state energy.

text: The Bose-Einstein condensation (BEC) of the ground state of bosonic atoms
in a trap was discussed. The BEC was proved for bosons with two-body repulsive
interaction potentials in the dilute limit, starting from the basic Schrodinger
equation. The BEC was 100% into the state which minimized the Gross-Pitaevskii
energy functional. The analysis also included rigorous proof of BEC in a physically
realistic, continuum model.

text: Using the Pauli-Fierz model of non-relativistic quantum electrodynamics, we
calculate the binding energy of an electron in the field of a nucleus of charge
Z and in presence of the quantized radiation field. We consider the case of small
coupling constant α, but fixed Zα and ultraviolet cut-off Λ. We prove that after
renormalizing the mass the binding energy has, to leading order in α, a finite
limit as Λ goes to infinity; i.e., the cut-off can be removed. The expression
for the ground state energy shift thus obtained agrees with Bethe's formula for
small values of Zα, but shows a different behavior for bigger values.
