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.

text: As the World Wide Web is growing rapidly, it is getting increasingly challenging
to gather representative information about it. Instead of crawling the web exhaustively
one has to resort to other techniques like sampling to determine the properties
of the web. A uniform random sample of the web would be useful to determine the
percentage of web pages in a specific language, on a topic or in a top level domain.
Unfortunately, no approach has been shown to sample the web pages in an unbiased
way. Three promising web sampling algorithms are based on random walks. They each
have been evaluated individually, but making a comparison on different data sets
is not possible. We directly compare these algorithms in this paper. We performed
three random walks on the web under the same conditions and analyzed their outcomes
in detail. We discuss the strengths and the weaknesses of each algorithm and propose
improvements based on experimental results.

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.'

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: 'We give polynomial-time algorithms for computing the values of Markov decision
processes (MDPs) with limsup and liminf objectives. A real-valued reward is assigned
to each state, and the value of an infinite path in the MDP is the limsup (resp.
liminf) of all rewards along the path. The value of an MDP is the maximal expected
value of an infinite path that can be achieved by resolving the decisions of the
MDP. Using our result on MDPs, we show that turn-based stochastic games with limsup
and liminf objectives can be solved in NP ∩ coNP. '

text: 'Ising models with pairwise interactions are the least structured, or maximum-entropy,
probability distributions that exactly reproduce measured pairwise correlations
between spins. Here we use this equivalence to construct Ising models that describe
the correlated spiking activity of populations of 40 neurons in the salamander
retina responding to natural movies. We show that pairwise interactions between
neurons account for observed higher-order correlations, and that for groups of
10 or more neurons pairwise interactions can no longer be regarded as small perturbations
in an independent system. We then construct network ensembles that generalize
the network instances observed in the experiment, and study their thermodynamic
behavior and coding capacity. Based on this construction, we can also create synthetic
networks of 120 neurons, and find that with increasing size the networks operate
closer to a critical point and start exhibiting collective behaviors reminiscent
of spin glasses. We examine closely two such behaviors that could be relevant
for neural code: tuning of the network to the critical point to maximize the ability
to encode diverse stimuli, and using the metastable states of the Ising Hamiltonian
as neural code words.'

text: There is a close analogy between statistical thermodynamics and the evolution
of allele frequencies under mutation, selection and random drift. Wright's formula
for the stationary distribution of allele frequencies is analogous to the Boltzmann
distribution in statistical physics. Population size, 2N, plays the role of the
inverse temperature, 1/kT, and determines the magnitude of random fluctuations.
Log mean fitness, View the MathML source, tends to increase under selection, and
is analogous to a (negative) energy; a potential function, U, increases under
mutation in a similar way. An entropy, SH, can be defined which measures the deviation
from the distribution of allele frequencies expected under random drift alone;
the sum View the MathML source gives a free fitness that increases as the population
evolves towards its stationary distribution. Usually, we observe the distribution
of a few quantitative traits that depend on the frequencies of very many alleles.
The mean and variance of such traits are analogous to observable quantities in
statistical thermodynamics. Thus, we can define an entropy, SΩ, which measures
the volume of allele frequency space that is consistent with the observed trait
distribution. The stationary distribution of the traits is View the MathML source;
this applies with arbitrary epistasis and dominance. The entropies SΩ, SH are
distinct, but converge when there are so many alleles that traits fluctuate close
to their expectations. Populations tend to evolve towards states that can be realised
in many ways (i.e., large SΩ), which may lead to a substantial drop below the
adaptive peak; we illustrate this point with a simple model of genetic redundancy.
This analogy with statistical thermodynamics brings together previous ideas in
a general framework, and justifies a maximum entropy approximation to the dynamics
of quantitative traits.

text: Why are sinistral snails so rare? Two main hypotheses are that selection acts
against the establishment of new coiling morphs, because dextral and sinistral
snails have trouble mating, or else a developmental constraint prevents the establishment
of sinistrals. We therefore used an isolate of the snail Lymnaea stagnalis, in
which sinistrals are rare, and populations of Partula suturalis, in which sinistrals
are common, as well as a mathematical model, to understand the circumstances by
which new morphs evolve. The main finding is that the sinistral genotype is associated
with reduced egg viability in L. stagnalis, but in P. suturalis individuals of
sinistral and dextral genotype appear equally fecund, implying a lack of a constraint.
As positive frequency-dependent selection against the rare chiral morph in P.
suturalis also operates over a narrow range (< 3%), the results suggest a model
for chiral evolution in snails in which weak positive frequency-dependent selection
may be overcome by a negative frequency-dependent selection, such as reproductive
character displacement. In snails, there is not always a developmental constraint.
As the direction of cleavage, and thus the directional asymmetry of the entire
body, does not generally vary in other Spiralia (annelids, echiurans, vestimentiferans,
sipunculids and nemerteans), it remains an open question as to whether this is
because of a constraint and/or because most taxa do not have a conspicuous external
asymmetry (like a shell) upon which selection can act.
acknowledgement: We owe a great debt to Jim Murray for his many contributions to the

text: In this paper we extend the work of Alfaro, Henzinger et al. on interface
theories for component-based design. Existing interface theories often fail to
capture functional relations between the inputs and outputs of an interface. For
example, a simple synchronous interface that takes as input a number n ≥ 0 and
returns, at the same time, as output n + 1, cannot be expressed in existing theories.
In this paper we provide a theory of relational interfaces, where such input-output
relations can be captured. Our theory supports synchronous interfaces, both stateless
and stateful. It includes explicit notions of environments and pluggability, and
satisfies fundamental properties such as preservation of refinement by composition,
and characterization of pluggability by refinement. We achieve these properties
by making reasonable restrictions on feedback loops in interface compositions.

text: 'We compare several languages for specifying Markovian population models such
as queuing networks and chemical reaction networks. These languages —matrix descriptions,
stochastic Petri nets, stoichiometric equations, stochastic process algebras,
and guarded command models— all describe continuous-time Markov chains, but they
differ according to important properties, such as compositionality, expressiveness
and succinctness, executability, ease of use, and the support they provide for
checking the well-formedness of a model and for analyzing a model. '

text: "Within systems biology there is an increasing interest in the stochastic
behavior of biochemical reaction networks. An appropriate stochastic description
is provided by the chemical master equation, which represents a continuous- time
Markov chain (CTMC).\r\nStandard Uniformization (SU) is an efficient method for
the transient analysis of CTMCs. For systems with very different time scales,
such as biochemical reaction networks, SU is computationally expensive. In these
cases, a variant of SU, called adaptive uniformization (AU), is known to reduce
the large number of iterations needed by SU. The additional difficulty of AU is
that it requires the solution of a birth process.\r\nIn this paper we present
an on-the-fly variant of AU, where we improve the original algorithm for AU at
the cost of a small approximation error. By means of several examples, we show
that our approach is particularly well-suited for biochemical reaction networks."

text: The Hierarchical Timing Language (HTL) is a real-time coordination language
for distributed control systems. HTL programs must be checked for well-formedness,
race freedom, transmission safety (schedulability of inter-host communication),
and time safety (schedulability of host computation). We present a modular abstract
syntax and semantics for HTL, modular checks of well-formedness, race freedom,
and transmission safety, and modular code distribution. Our contributions here
complement previous results on HTL time safety and modular code generation. Modularity
in HTL can be utilized in easy program composition as well as fast program analysis
and code generation, but also in so-called runtime patching, where program components
may be modified at runtime.

text: Games on graphs with omega-regular objectives provide a model for the control
and synthesis of reactive systems. Every omega-regular objective can be decomposed
into a safety part and a liveness part. The liveness part ensures that something
good happens “eventually.” Two main strengths of the classical, infinite-limit
formulation of liveness are robustness (independence from the granularity of transitions)
and simplicity (abstraction of complicated time bounds). However, the classical
liveness formulation suffers from the drawback that the time until something good
happens may be unbounded. A stronger formulation of liveness, so-called finitary
liveness, overcomes this drawback, while still retaining robustness and simplicity.
Finitary liveness requires that there exists an unknown, fixed bound b such that
something good happens within b transitions. While for one-shot liveness (reachability)
objectives, classical and finitary liveness coincide, for repeated liveness (Buchi)
objectives, the finitary formulation is strictly stronger. In this work we study
games with finitary parity and Streett objectives. We prove the determinacy of
these games, present algorithms for solving these games, and characterize the
memory requirements of winning strategies. We show that finitary parity games
can be solved in polynomial time, which is not known for infinitary parity games.
For finitary Streett games, we give an EXPTIME algorithm and show that the problem
is NP-hard. Our algorithms can be used, for example, for synthesizing controllers
that do not let the response time of a system increase without bound.

text: 'Nondeterministic weighted automata are finite automata with numerical weights
oil transitions. They define quantitative languages 1, that assign to each word
v; a real number L(w). The value of ail infinite word w is computed as the maximal
value of all runs over w, and the value of a run as the supremum, limsup liminf,
limit average, or discounted sum of the transition weights. We introduce probabilistic
weighted antomata, in which the transitions are chosen in a randomized (rather
than nondeterministic) fashion. Under almost-sure semantics (resp. positive semantics),
the value of a word v) is the largest real v such that the runs over w have value
at least v with probability I (resp. positive probability). We study the classical
questions of automata theory for probabilistic weighted automata: emptiness and
universality, expressiveness, and closure under various operations oil languages.
For quantitative languages, emptiness university axe defined as whether the value
of some (resp. every) word exceeds a given threshold. We prove some, of these
questions to he decidable, and others undecidable. Regarding expressive power,
we show that probabilities allow its to define a wide variety of new classes of

text: We compare anti-parasite defences at the level of multicellular organisms
and insect societies, and find that selection by parasites at these two organisational
levels is often very similar and has created a number of parallel evolutionary
solutions in the host's immune response. The defence mechanisms of both individuals
and insect colonies start with border defences to prevent parasite intake and
are followed by soma defences that prevent the establishment and spread of the
parasite between the body's cells or the social insect workers. Lastly, germ line
defences are employed to inhibit infection of the reproductive tissue of organisms
or the reproductive individuals in colonies. We further find sophisticated self/non-self-recognition
systems operating at both levels, which appear to be vital in maintaining the
integrity of the body or colony as a reproductive entity. We then expand on the
regulation of immune responses and end with a contemplation of how evolution may
shape the different immune components, both within and between levels. The aim
of this review is to highlight common evolutionary principles acting in disease
defence at the level of both individual organisms and societies, thereby linking
the fields of physiological and ecological immunology.

text: We describe an algorithm for segmenting three-dimensional medical imaging
data modeled as a continuous function on a 3-manifold. It is related to watershed
algorithms developed in image processing but is closer to its mathematical roots,
which are Morse theory and homological algebra. It allows for the implicit treatment
of an underlying mesh, thus combining the structural integrity of its mathematical
foundations with the computational efficiency of image processing.

text: 'Populations living in a spatially and temporally changing environment can
adapt to the changing optimum and/or migrate toward favorable habitats. Here we
extend previous analyses with a static optimum to allow the environment to vary
in time as well as in space. The model follows both population dynamics and the
trait mean under stabilizing selection, and the outcomes can be understood by
comparing the loads due to genetic variance, dispersal, and temporal change. With
fixed genetic variance, we obtain two regimes: (1) adaptation that is uniform
along the environmental gradient and that responds to the moving optimum as expected
for panmictic populations and when the spatial gradient is sufficiently steep,
and (2) a population with limited range that adapts more slowly than the environmental
optimum changes in both time and space; the population therefore becomes locally
extinct and migrates toward suitable habitat. We also use a population‐genetic
model with many loci to allow genetic variance to evolve, and we show that the
only solution now has uniform adaptation.'

text: 'Felsenstein distinguished two ways by which selection can directly strengthen
isolation. First, a modifier that strengthens prezygotic isolation can be favored
everywhere. This fits with the traditional view of reinforcement as an adaptation
to reduce deleterious hybridization by strengthening assortative mating. Second,
selection can favor association between different incompatibilities, despite recombination.
We generalize this “two allele” model to follow associations among any number
of incompatibilities, which may include both assortment and hybrid inviability.
Our key argument is that this process, of coupling between incompatibilities,
may be quite different from the usual view of reinforcement: strong isolation
can evolve through the coupling of any kind of incompatibility, whether prezygotic
or postzygotic. Single locus incompatibilities become coupled because associations
between them increase the variance in compatibility, which in turn increases mean
fitness if there is positive epistasis. Multiple incompatibilities, each maintained
by epistasis, can become coupled in the same way. In contrast, a single-locus
incompatibility can become coupled with loci that reduce the viability of haploid
hybrids because this reduces harmful recombination. We obtain simple approximations
for the limits of tight linkage, and strong assortment, and show how assortment
alleles can invade through associations with other components of reproductive
isolation.'
