710.1453 | Hadron production in deuteron-gold collisions and nuclear parton
distributions | We calculate nuclear modification factors $R_{dAu}$, central-to-peripheral
ratios, $R_{CP}$, and pseudorapidity asymmetries $Y_{Asym}$ in deuteron-gold
collisions at $\sqrt{s} = 200$ GeV in the framework of leading-order (LO)
perturbative Quantum Chromodynamics. We use the Eskola-Kolhinen-Salgado (EKS),
the Frankfurt-Guzey-Strikman (FGS) and the Hirai-Kumano-Nagai (HKN) nuclear
parton distribution functions and the Albino-Kramer-Kniehl (AKK) fragmentation
functions in our calculations. Results are compared to experimental data from
the BRAHMS and STAR collaborations.

Model | We study flavor-changing neutral current and CP violations in the minimal
supersymmetric left-right model. We calculate the beyond-standard-model
contributions to the neutral kaon mixing $\Delta M_K$ and $\epsilon$, and find
possible to have a numerical cancelation between the contributions from the
right-handed gauge boson and supersymmetric box diagram. With the cancelation,
the right-handed $W$-boson mass scale can be lowered to about 2 TeV, well
within the search limit of LHC.

710.1455 | Superrecursive Features of Interactive Computation | Functioning and interaction of distributed devices and concurrent algorithms
are analyzed in the context of the theory of algorithms. Our main concern here
is how and under what conditions algorithmic interactive devices can be more
powerful than the recursive models of computation, such as Turing machines.
Realization of such a higher computing power makes these systems
superrecursive. We find here five sources for superrecursiveness in
interaction. In addition, we prove that when all of these sources are excluded,
the algorithmic interactive system in question is able to perform only
recursive computations. These results provide computer scientists with
necessary and sufficient conditions for achieving superrecursiveness by
algorithmic interactive devices.

rays. In this paper, we show that those solutions are classified by asymptotic
information of the solution as $|y| \to \infty$. Our study then unravels some
interesting relations between the line-soliton classification scheme and
classical results in the theory of permutations.

710.1457 | Effective Coupling Constant in Renormalization Group for the Quantum
Electrodynamics | Effective coupling constant in quantum electrodynamics is investigated. A
pole appears in the effective coupling constant for the space-like momentum if
it is calculated by perturbation. The pole can be eliminated by the analytic
regularization. For QED the effective coupling constant is written in terms of
the scale parameter, $\Lambda$, having the dimension of mass as in the case of
QCD. $\Lambda$ is determined by comparing with the experimental data. The
calculated result agrees with experiment with $\Lambda\approx 1.64\times
10^{47}$ GeV; it is very large but much smaller than the mass scale of Landau
ghost.

710.1458 | Broad-line Balmer Decrements in Blue Active Galactic Nuclei | We have investigated the broad-line Balmer decrements (Halpha/Hbeta) for a
large, homogeneous sample of Seyfert 1 galaxies and QSOs using spectroscopic
data obtained in the Sloan Digital Sky Survey. The sample, drawn from the
Fourth Data Release, comprises 446 low redshift (z < 0.35) active galactic
nuclei (AGN) that have blue optical continua as indicated by the spectral
slopes in order to minimize the effect of dust extinction. We find that (i) the
distribution of the intrinsic broad-line Halpha/Hbeta ratio can be well
described by log-Gaussian, with a peak at Halpha/Hbeta=3.06 and a standard
deviation of about 0.03 dex only; (ii) the Balmer decrement does not correlate
with AGN properties such as luminosity, accretion rate, and continuum slope,
etc.; (iii) on average, the Balmer decrements are found to be only slightly
larger in radio-loud sources (3.37) and sources having double-peaked
emission-line profiles (3.27) compared to the rest of the sample. We therefore
suggest that the broad-line Halpha/Hbeta ratio can be used as a good indicator
for dust extinction in the AGN broad-line region; this is especially true for
radio-quiet AGN with regular emission-line profiles, which constitute the vast
majority of the AGN population.

710.1459 | Geometry and complexity of O'Hara's algorithm | In this paper we analyze O'Hara's partition bijection. We present three type
of results. First, we show that O'Hara's bijection can be viewed geometrically
as a certain scissor congruence type result. Second, we obtain a number of new
complexity bounds, proving that O'Hara's bijection is efficient in several
special cases and mildly exponential in general. Finally, we prove that for
identities with finite support, the map of the O'Hara's bijection can be
computed in polynomial time, i.e. much more efficiently than by O'Hara's
construction.

710.146 | Exact Static Solutions of a Generalized Discrete \phi^4 Model Including
Short-Periodic Solutions | For a five-parameter discrete $\phi^4$ model, we derive various exact static
solutions, including the staggered ones, in the form of the basic Jacobi
elliptic functions $\sn$, $\cn$, and $\dn$, and also in the form of their
hyperbolic function limits such as kink ($\tanh$) and single-humped pulse
($\sech$) solutions. Such solutions are admitted by the considered model in
seven cases, two of which have been discussed in the literature, and the
remaining five cases are addressed here. We also obtain $\sin$e, staggered
$\sin$e as well as a large number of short-periodic static solutions of the
generalized 5-parameter model. All the Jacobi elliptic, hyperbolic and
trigonometric function solutions (including the staggered ones) are
translationally invariant (TI), i.e., they can be shifted along the lattice by
an arbitrary $x_0$, but among the short-periodic solutions there are both TI
and non-TI solutions. The stability of these solutions is also investigated.
Finally, the constructed Jacobi elliptic function solutions reveal four new
types of cubic nonlinearity with the TI property.

710.1461 | A large deviation approach to optimal transport | A probabilistic method for solving the Monge-Kantorovich mass transport
problem on $R^d$ is introduced. A system of empirical measures of independent
particles is built in such a way that it obeys a doubly indexed large deviation
principle with an optimal transport cost as its rate function. As a
consequence, new approximation results for the optimal cost function and the
optimal transport plans are derived. They follow from the Gamma-convergence of
a sequence of normalized relative entropies toward the optimal transport cost.

710.1464 | Study of Hadron Scattering Using an Asymmetric Box | We propose to study hadron-hadron scattering using lattice QCD in an
asymmetric box which allows one to access more non-degenerate low-momentum
modes for a given volume. The conventional L\"{u}scher's formula applicable in
a symmetric box is modified accordingly. To illustrate the feasibility of this
approach, pion-pion elastic scattering phase shifts in the I=2, J=0 channel are
calculated within quenched approximation using improved gauge and Wilson
fermion actions on anisotropic lattices in an asymmetric box. After the chiral
and continuum extrapolation, we find that our quenched results for the
scattering phase shifts in this channel are consistent with the experimental
data when the three-momentum of the pion is below 300MeV. Agreement is also
found when compared with previous theoretical results from lattice and other
means. Moreover, with the usage of asymmetric volume, we are able to compute
the scattering phases in the low-momentum range (pion three momentum less than
about 350MeV in the center of mass frame) for over a dozen values of the pion

experiments on actin filaments and the considerable current interest in polymer
networks. We obtain simple, approximate analytical forms for the
force-extension relations and compare these with numerical treatments. We note
the important role of boundary conditions in determining force-extension
relations. The theoretical predictions presented here can be tested against
single molecule experiments on neurofilaments and cytoskeletal filaments like
actin and microtubules. Our work is motivated by the buckling of the
cytoskeleton of a cell under compression, a phenomenon of interest to biology.

710.147 | Asymmetry of near-critical percolation interfaces | We study the possible scaling limits of percolation interfaces in two
dimensions on the triangular lattice. When one lets the percolation parameter
p(N) vary with the size N of the box that one is considering, three
possibilities arise in the large-scale limit. It is known that when p(N) does
not converge to 1/2 fast enough, then the scaling limits are degenerate,
whereas if p(N) - 1 / 2 goes to zero quickly, the scaling limits are SLE(6) as
when p=1/2. We study some properties of the (non-void) intermediate regime
where the large scale behavior is neither SLE(6) nor degenerate. We prove that
in this case, the law of any scaling limit is singular with respect to that of

710.1471 | New determination of the size and bulk density of the binary asteroid 22
Kalliope from observations of mutual eclipses | In 2007, the M-type binary asteroid 22 Kalliope reached one of its annual
equinoxes. As a consequence, the orbit plane of its small moon, Linus, was
aligned closely to the Sun's line of sight, giving rise to a mutual eclipse
season. A dedicated international campaign of photometric observations, based
on amateur-professional collaboration, was organized and coordinated by the
IMCCE in order to catch several of these events. The set of the compiled
observations is released in this work. We developed a relevant model of these
events, including a topographic shape model of Kalliope refined in the present
work, the orbit solution of Linus as well as the photometric effect of the
shadow of one component falling on the other. By fitting this model to the only
two full recorded events, we derived a new estimation of the equivalent
diameter of Kalliope of 166.2+/-2.8km, 8% smaller than its IRAS diameter. As to
the diameter of Linus, considered as purely spherical, it is estimated to
28+/-2 km. This substantial "shortening" of Kalliope gives a bulk density of
3.35+/-0.33g/cm3, significantly higher than past determinations but more
consistent with its taxonomic type. Some constraints can be inferred on the
composition.

710.1472 | Optical Variability of the Radio Source J 1128+5925 | Very recently, J 1128+5925 was found to show strong intraday variability at
radio wavelengths and may be a new source with annual modulation of the
timescale of its radio variability. Therefore, its radio variability can be
best explained via interstellar scintillation. Here we present the properties
of its optical variability for the first time after a monitoring program in
2007 May. Our observations indicate that in this period J 1128+5925 only showed
trivial optical variability on internight timescale, and did not show any clear
intranight variability. This behavior is quite different from its strong radio
intraday variability. Either this object was in a quiescent state in optical in

710.1473 | Integrated properties of mass segregated star clusters | In this contribution we study integrated properties of dynamically segregated
star clusters. The observed core radii of segregated clusters can be 50%
smaller than the ``true'' core radius. In addition, the measured radius in the
red filters is smaller than those measured in blue filters. However, these
difference are small ($\lesssim10%$), making it observationally challenging to
detect mass segregation in extra-galactic clusters based on such a comparison.
Our results follow naturally from the fact that in nearly all filters most of
the light comes from the most massive stars. Therefore, the observed surface
brightness profile is dominated by stars of similar mass, which are centrally
concentrated and have a similar spatial distribution.

short-hard bursts in optical and radio observations, different progenitors for
short-hard bursts and long-soft bursts have been suggested. Based on the X-ray
afterglow observation and the cumulative red-shift distribution of short-hard
bursts, Nakar et al. (2006) found that the progenitors of short-hard bursts are
consistent with old populations, such as mergers of binary neutron stars.
Recently, the existence of two subclasses in long-soft bursts has been
suggested after considering multiple characteristics of gamma-ray bursts,
including fluences and the duration time. In this work, we extended the
analysis of cumulative red-shift distribution to two possible subclasses in
L-GRBs. We found that two possible subclass GRBs show different red-shift
distributions, especially for red-shifts z > 1. Our results indicate that the
accumulative red-shift distribution can be used as a tool to constrain the
progenitor characteristics of possible subclasses in L-GRBs.

710.1478 | Angular decorrelations in Mueller-Navelet jets and DIS | We discuss the azimuthal angle decorrelation of Mueller-Navelet jets at
hadron colliders and forward jets in Deep Inelastic Scattering within the BFKL
framework with a NLO kernel. We stress the need of collinear improvements to

710.1479 | On superconformal projective hypermultiplets | Building on the five-dimensional constructions in hep-th/0601177, we provide
a unified description of four-dimensional N = 2 superconformal off-shell
multiplets in projective superspace, including a realization in terms of N = 1
superfields. In particular, superconformal polar multiplets are consistently
defined for the first time. We present new 4D N = 2 superconformal sigma-models
described by polar multiplets. Such sigma-models realize general superconformal
couplings in projective superspace, but involve an infinite tale of auxiliary N
= 1 superfields. The auxiliaries should be eliminated by solving infinitely
many algebraic nonlinear equations, and this is a nontrivial technical problem.
We argue that the latter can be avoided by making use of supersymmetry
considerations. All information about the resulting superconformal model (and
hence the associated superconformal cone) is encoded in the so-called canonical
coordinate system for a Kaehler metric, which was introduced by Bochner and
Calabi in the late 1940s.

710.148 | Density of neutral interstellar hydrogen at the termination shock from
Ulysses pickup ion observations | By reevaluating a 13-month stretch of Ulysses SWICS H pickup ion measurements
near 5 AU close to the ecliptic right after the previous solar minimum, this
paper presents a determination of the neutral interstellar H density at the
solar wind termination shock and implications for the density and ionization
degree of hydrogen in the LIC. The density of neutral interstellar hydrogen at
the termination shock was determined from the local pickup ion production rate
as obtained close to the cut-off in the distribution function at aphelion of
Ulysses. As shown in an analytical treatment for the upwind axis and through
kinetic modeling of the pickup ion production rate at the observer location,
with variations in the ionization rate, radiation pressure, and the modeling of
the particle behavior, this analysis turns out to be very robust against
uncertainties in these parameters and the modeling. Analysis using current

710.1481 | What's in a Name? | This paper describes experiments on identifying the language of a single name
in isolation or in a document written in a different language. A new corpus has
been compiled and made available, matching names against languages. This corpus
is used in a series of experiments measuring the performance of general
language models and names-only language models on the language identification
task. Conclusions are drawn from the comparison between using general language
models and names-only language models and between identifying the language of
isolated names and the language of very short document fragments. Future
research directions are outlined.

710.1482 | Heap Reference Analysis for Functional Programs | Current garbage collectors leave a lot of garbage uncollected because they
conservatively approximate liveness by reachability from program variables. In
this paper, we describe a sequence of static analyses that takes as input a
program written in a first-order, eager functional programming language, and
finds at each program point the references to objects that are guaranteed not
to be used in the future. Such references are made null by a transformation
pass. If this makes the object unreachable, it can be collected by the garbage
collector. This causes more garbage to be collected, resulting in fewer
collections. Additionally, for those garbage collectors which scavenge live
objects, it makes each collection faster.
The interesting aspects of our method are both in the identification of the
analyses required to solve the problem and the way they are carried out. We
identify three different analyses -- liveness, sharing and accessibility. In
liveness and sharing analyses, the function definitions are analyzed
independently of the calling context. This is achieved by using a variable to
represent the unknown context of the function being analyzed and setting up
constraints expressing the effect of the function with respect to the variable.
The solution of the constraints is a summary of the function that is
parameterized with respect to a calling context and is used to analyze function
calls. As a result we achieve context sensitivity at call sites without
analyzing the function multiple number of times.

710.1483 | The complex of pant decompositions of a surface | We exhibit a set of edges (moves) and 2-cells (relations) making the complex
of pant decompositions on a surface a simply connected complex. Our
construction, unlike the previous ones, keeps the arguments concerning the
structural transformations independent from those deriving from the action of
the mapping class group. The moves and the relations turn out to be supported
in subsurfaces with 3g-3+n=1,2 (where g is the genus and n is the number of
boundary components), illustrating in this way the so called Grothendieck
principle.

710.1486 | Type Ia supernovae as speed sensors at intermediate redshifts | The application of large scale peculiar velocity (LSPV), as a crucial probe
of dark matter, dark energy and gravity, is severely limited by measurement
obstacles. We show that fluctuations in type Ia supernovae (SNe Ia) fluxes
induced by LSPV offer a promising approach to measure LSPV at intermediate
redshifts. In the 3D Fourier space, gravitational lensing, the dominant
systematical error, is well suppressed, localized and can be further corrected
effectively. Advance in SN observations can further significantly reduce shot
noise induced by SN intrinsic fluctuations, which is the dominant statistical
error. Robust mapping on the motion of the dark universe through SNe Ia is thus
feasible to $z\sim 0.5$.

710.1488 | Flavor Changing Neutral Current Processes in a SO(10) SUSY GUT with
Family Symmetry | We report on a detailed analysis of a SO(10) SUSY GUT model of Dermisek and
Raby (DR) with a D3 family symmetry. The model is completely specified in terms
of only 24 parameters and is able to successfully describe both quark and
lepton masses and mixings, except for |Vub| that turns out to be too low.
However, a global fit shows that flavor changing (FC) processes like Bs --> mu+
mu-, Bs-mixing, B+ --> tau+ nu, B --> Xs gamma and B --> Xs l+ l- pose a
serious problem to the DR model. The simultaneous description of these FC

710.1489 | Lepton Flavour Violating Effects on Chargino Production at the ILC | We review the influence of lepton flavour violation (LFV) on the production
processes e+e- -> ~chi+_i ~chi-_j at the International Linear Collider (ILC)
with longitudinal e+ and e- beam polarizations in the framework of the Minimal
Supersymmetric Standard Model (MSSM). The t-channel sneutrino exchange
contribution to the processes e+e- -> ~chi+_i ~chi-_j is modified in the case
of LFV, as the sneutrino mass eigenstates have no definite flavour, and
therefore more than one sneutrino can contribute. This influence can alter the
cross section sigma(e+e- -> ~chi+_1 ~chi-_1) by a factor of 2 or more when
varying the LFV mixing angles, in accordance with the restrictions due to the
current limits on rare lepton decays. Hence, the inclusion of LFV parameters
can be important when deducing the underlying model parameters from measured
observables such as sigma(e+e- -> ~chi+_1 ~chi-_1).

710.149 | Electrostatic control of quantum dot entanglement induced by coupling to
external reservoirs | We propose a quantum transport experiment to prepare and measure
charge-entanglement between two electrostatically defined quantum dots.
Coherent population trapping, as realized in cavity quantum electrodynamics,
can be carried out by using a third quantum dot to play the role of the optical
cavity. In our proposal, a pumping which is quantum mechanically
indistinguishable for the quantum dots drives the system into a state with a
high degree of entanglement. The whole effect can be switched on and off by

710.1491 | Dust, pulsation, chromospheres and their role in driving mass loss from
red giants in Galactic globular clusters | Context: Mass loss from red giants in old globular clusters affects the
horizontal branch (HB) morphology and post-HB stellar evolution including the
production of ultraviolet-bright stars, dredge up of nucleosynthesis products
and replenishment of the intra-cluster medium. Studies of mass loss in globular
clusters also allows one to investigate the metallicity dependence of the mass
loss from cool, low-mass stars down to very low metallicities.
Aims: We present an analysis of new VLT/UVES spectra of 47 red giants in the
Galactic globular clusters 47 Tuc (NGC 104), NGC 362, omega Cen (NGC 5139), NGC
6388, M54 (NGC 6715) and M15 (NGC 7078). The spectra cover the wavelength
region 6100-9900A at a resolving power of R = 110,000. Some of these stars are
known to exhibit mid-infrared excess emission indicative of circumstellar dust.
Our aim is to detect signatures of mass loss, identify the mechanism(s)
responsible for such outflows, and measure the mass-loss rates.
Methods: We determine for each star its effective temperature, luminosity,
radius and escape velocity. We analyse the H-alpha and near-infrared calcium
triplet lines for evidence of outflows, pulsation and chromospheric activity,
and present a simple model for estimating mass-loss rates from the H-alpha line
profile. We compare our results with a variety of other, independent methods.
Results: We argue that a chromosphere persists in Galactic globular cluster
giants and controls the mass-loss rate to late-K/early-M spectral types, where
pulsation becomes strong enough to drive shock waves at luminosities above the
RGB tip. This transition may be metallicity-dependent. We find mass-loss rates
of ~10^-7 to 10^-5 solar masses per year, largely independent of metallicity.

710.1492 | Precise Formulation of Neutrino Oscillation in the Earth | We give a perturbation theory of neutrino oscillation in the Earth. The
perturbation theory is valid for neutrinos with energy $E \gsim 0.5$ GeV. It is
formulated using trajectory dependent average potential. Non-adiabatic
contributions are included as the first order effects in the perturbation
theory. We analyze neutrino oscillation with standard matter effect and with
non-standard matter effect. In a three flavor analysis we show that the
perturbation theory gives a precise description of neutrino conversion in the

710.1494 | Singular Scaling Functions in Clustering Phenomena | We study clustering in a stochastic system of particles sliding down a
fluctuating surface in one and two dimensions. In steady state, the
density-density correlation function is a scaling function of separation and
system size.This scaling function is singular for small argument -- it exhibits
a cusp singularity for particles with mutual exclusion, and a divergence for
noninteracting particles. The steady state is characterized by giant
fluctuations which do not damp down in the thermodynamic limit. The
autocorrelation function is a singular scaling function of time and system
size. The scaling properties are surprisingly similar to those for particles
moving in a quenched disordered environment that results if the surface is
frozen.

710.1497 | Are galaxies with AGN a transition population? | We present the results of an analysis of a well-selected sample of galaxies
with active and inactive galactic nuclei from the Sloan Digital Sky Survey, in
the range 0.01 < z < 0.16. The SDSS galaxy catalogue was split into two classes
of active galaxies, Type~2 AGN and composites, and one set of inactive,
star-forming/passive galaxies. For each active galaxy, two inactive control
galaxies were selected by matching redshift, absolute magnitude, inclination,
and radius. The sample of inactive galaxies naturally divides into a red and a
blue sequence, while the vast majority of AGN hosts occur along the red
sequence. In terms of H-alpha equivalent width, the population of composite
galaxies peaks in the valley between the two modes, suggesting a transition
population. However, this effect is not observed in other properties such as
colour-magnitude space, or colour-concentration plane. Active galaxies are seen
to be generally bulge-dominated systems, but with enhanced H-alpha emission
compared to inactive red-sequence galaxies. AGN and composites also occur in
less dense environments than inactive red-sequence galaxies, implying that the
fuelling of AGN is more restricted in high-density environments. These results
are therefore inconsistent with theories in which AGN host galaxies are a
`transition' population. We also introduce a systematic 3D spectroscopic
imaging survey, to quantify and compare the gaseous and stellar kinematics of a
well-selected, distance-limited sample of up to 20 nearby Seyfert galaxies, and
20 inactive control galaxies with well-matched optical properties. The survey
aims to search for dynamical triggers of nuclear activity and address
outstanding controversies in optical/IR imaging surveys.

710.1498 | Diffractive photoproduction of dijets in ep collisions at HERA | Diffractive photoproduction of dijets was measured with the ZEUS detector at
the ep collider HERA using an integrated luminosity of 77.2 pb-1. The
measurements were made in the kinematic range Q^2 < 1 GeV^2, 0.20 < y < 0.85
and x_pom < 0.025, where Q^2 is the photon virtuality, y is the inelasticity
and x_pom is the fraction of the proton momentum taken by the diffractive
exchange. The two jets with the highest transverse energy, E_T^jet, were
required to satisfy E_T^jet > 7.5 and 6.5 GeV, respectively, and to lie in the
pseudorapidity range -1.5 < eta^jet < 1.5. Differential cross sections were
compared to perturbative QCD calculations using available parameterisations of
diffractive parton distributions of the proton.

710.1499 | Approximating max-min linear programs with local algorithms | A local algorithm is a distributed algorithm where each node must operate
solely based on the information that was available at system startup within a
constant-size neighbourhood of the node. We study the applicability of local
algorithms to max-min LPs where the objective is to maximise $\min_k \sum_v
c_{kv} x_v$ subject to $\sum_v a_{iv} x_v \le 1$ for each $i$ and $x_v \ge 0$
for each $v$. Here $c_{kv} \ge 0$, $a_{iv} \ge 0$, and the support sets $V_i =
\{v : a_{iv} > 0 \}$, $V_k = \{v : c_{kv}>0 \}$, $I_v = \{i : a_{iv} > 0 \}$
and $K_v = \{k : c_{kv} > 0 \}$ have bounded size. In the distributed setting,
each agent $v$ is responsible for choosing the value of $x_v$, and the
communication network is a hypergraph $\mathcal{H}$ where the sets $V_k$ and
$V_i$ constitute the hyperedges. We present inapproximability results for a
wide range of structural assumptions; for example, even if $|V_i|$ and $|V_k|$
are bounded by some constants larger than 2, there is no local approximation
scheme. To contrast the negative results, we present a local approximation
algorithm which achieves good approximation ratios if we can bound the relative
growth of the vertex neighbourhoods in $\mathcal{H}$.

710.15 | A 610-MHz survey of the ELAIS-N1 field with the Giant Metrewave Radio
Telescope - Observations, data analysis and source catalogue | Observations of the ELAIS-N1 field taken at 610 MHz with the Giant Metrewave
Radio Telescope are presented. Nineteen pointings were observed, covering a
total area of 9 square degrees with a resolution of 6" x 5", PA +45 deg. Four
of the pointings were deep observations with an rms of 40 microJy before
primary beam correction, with the remaining fifteen pointings having an rms of
70 microJy. The techniques used for data reduction and production of a
mosaicked image of the region are described, and the final mosaic is presented,
along with a catalogue of 2500 sources detected above 6 sigma. This work
complements the large amount of optical and infrared data already available on
the region. We calculate 610-MHz source counts down to 270 microJy, and find

710.1502 | Efficient 2-designs from bases exist | We show that in a complex d-dimensional vector space, one can find O(d) bases
whose elements form a 2-design. Such vector sets generalize the notion of a
maximal collection of mutually unbiased bases (MUBs). MUBs have manifold
applications in quantum information theory (e.g. in state tomography, cloning,
or cryptography) -- however it is suspected that maximal sets exist only in
prime-power dimensions. Our construction offers an efficient alternative for
general dimensions. The findings are based on a framework recently established
in [A. Roy and A. Scott, J. Math. Phys. 48, 072110 (2007)], which reduces the
construction of such bases to the combinatorial problem of finding certain
highly nonlinear functions between abelian groups.

i.e., 1_(10)-1_(01), 1_(11)-0_(00), and 2_(12)-1_(01), are predicted in
absorption, all the others in emission. This behaviour changes for models with
a water abundance jump profile in that the line profiles for jumps by a factor
of ~10-100 are similar to the line shapes in the constant abundance models,
whereas larger jumps lead to emission profiles. Asymmetric line profiles are
found for models with a cavity outflow and depend on the inclination angle.
Models with an outflow cavity are favoured to reproduce the SWAS observations
of the 1_(10)-1_(01) ground-state transition. PACS spectra will tell us about
the geometry of these regions, both through the continuum and through the
lines. Conclusions: it is found that the low-lying transitions of water are
sensitive to outflow features, and represent the excitation conditions in the
outer regions. High-lying transitions are more sensitive to the adopted density
and temperature distribution which probe the inner excitation conditions. The
Herschel mission will thus be very helpful to constrain the physical and
chemical structure of high-mass star-forming regions such as AFGL2591.

710.1506 | Water vapor emission from IRC+10216 and other carbon-rich stars: model
predictions and prospects for multitransition observations | We have modeled the emission of H2O rotational lines from the extreme C-rich
star IRC+10216. Our treatment of the excitation of H2O emissions takes into
account the excitation of H2O both through collisions, and through the pumping
of the nu2 and nu3 vibrational states by dust emission and subsequent decay to
the ground state. Regardless of the spatial distribution of the water
molecules, the H2O 1_{10}-1_{01} line at 557 GHz observed by the Submillimeter
Wave Astronomy Satellite (SWAS) is found to be pumped primarily through the
absorption of dust-emitted photons at 6 $\mu$m in the nu2 band. As noted by
previous authors, the inclusion of radiative pumping lowers the ortho-H2O
abundance required to account for the 557 GHz emission, which is found to be
(0.5-1)x10^{-7} if the presence of H2O is a consequence of vaporization of
orbiting comets or Fischer-Tropsch catalysis. Predictions for other
submillimeter H2O lines that can be observed by the Herschel Space Observatory
(HSO) are reported. Multitransition HSO observations promise to reveal the
spatial distribution of the circumstellar water vapor, discriminating among the
several hypotheses that have been proposed for the origin of the H2O vapor in
the envelope of IRC+10216. We also show that, for observations with HSO, the
H2O 1_{10}-1_{01} 557 GHz line affords the greatest sensitivity in searching
for H2O in other C-rich AGB stars.

710.1507 | Critical Behavior of CP^1 at theta = pi, Haldane's Conjecture and the
Universality Class | Using an approach to analyze the theta dependence of systems with a
theta-term we recently proposed, the critical behavior of CP^1 at theta=pi is
studied. We find a region outside the strong coupling regime where Haldane's
conjecture is verified. The critical line however does not belong to the

710.1509 | Asymptotic Behavior of Inflated Lattice Polygons | We study the inflated phase of two dimensional lattice polygons with fixed
perimeter $N$ and variable area, associating a weight $\exp[pA - Jb ]$ to a
polygon with area $A$ and $b$ bends. For convex and column-convex polygons, we
show that $<A >/A_{max} = 1 - K(J)/\tilde{p}^2 +
\mathcal{O}(\rho^{-\tilde{p}})$, where $\tilde{p}=pN \gg 1$, and $\rho<1$. The
constant $K(J)$ is found to be the same for both types of polygons. We argue
that self-avoiding polygons should exhibit the same asymptotic behavior. For
self-avoiding polygons, our predictions are in good agreement with exact
enumeration data for J=0 and Monte Carlo simulations for $J \neq 0$. We also
study polygons where self-intersections are allowed, verifying numerically that
the asymptotic behavior described above continues to hold.

\Omega_{m,0}\le 0.35$. Models with a constant equation of state inside General
Relativity (GR) are characterized by a quasi-constant $\gamma'_0$, for
$\Omega_{m,0}=0.3$ for example we have $\gamma'_0\approx -0.02$ while
$\gamma_0$ can have a nonnegligible variation. A smoothly varying equation of
state inside GR does not produce either $|\gamma'_0|>0.02$. A measurement of
$\gamma(z)$ on small redshifts could help discriminate between various DE
models even if their $\gamma_0$ is close, a possibility interesting for DE
models outside GR for which a significant $\gamma'_0$ can be obtained.

710.1511 | Demographic growth and the distribution of language sizes | It is argued that the present log-normal distribution of language sizes is,
to a large extent, a consequence of demographic dynamics within the population
of speakers of each language. A two-parameter stochastic multiplicative process
is proposed as a model for the population dynamics of individual languages, and
applied over a period spanning the last ten centuries. The model disregards
language birth and death. A straightforward fitting of the two parameters,
which statistically characterize the population growth rate, predicts a
distribution of language sizes in excellent agreement with empirical data.
Numerical simulations, and the study of the size distribution within language
families, validate the assumptions at the basis of the model.

710.1512 | Prompt dipole radiation in fusion reactions | The prompt gamma ray emission was investigated in the 16A MeV energy region
by means of the 36,40Ar+96,92Zr fusion reactions leading to a compound nucleus
in the vicinity of 132Ce. We show that the prompt radiation, which appears to
be still effective at such a high beam energy, has an angular distribution
pattern consistent with a dipole oscillation along the symmetry axis of the

710.1514 | Intermediate rank and property RD | We introduce concepts of intermediate rank for countable groups that
"interpolate" between consecutive values of the classical (integer-valued)
rank. Various classes of groups are proved to have intermediate rank behaviors.
We are especially interested in interpolation between rank 1 and rank 2. For
instance, we construct groups "of rank 7/4". Our setting is essentially that of
non positively curved spaces, where concepts of intermediate rank include
polynomial rank, local rank, and mesoscopic rank. The resulting framework has
interesting connections to operator algebras. We prove property RD in many
cases where intermediate rank occurs. This gives a new family of groups
satisfying the Baum-Connes conjecture. We prove that the reduced $C^*$-algebras
of groups of rank 7/4 have stable rank 1.

710.1515 | Ferromagnetic-like closure domains in ferroelectric ultrathin films | We simulate from first-principles the energetic, structural, and electronic
properties of ferroelectric domains in ultrathin capacitors made of a few unit
cells of BaTiO$_3$ between two metallic SrRuO$_3$ electrodes in short circuit.
The domains are stabilized down to two unit cells, adopting the form of a
domain of closure, common in ferromagnets but only recently detected
experimentally in ferroelectric thin films. The domains are closed by the
in-plane relaxation of the atoms in the first SrO layer of the electrode, that
behaves more like SrO in highly polarizable SrTiO$_3$ than in metallic
SrRuO$_3$. Even if small, these lateral displacements are essential to
stabilize the domains, and might provide some hints to explain why some systems
break into domains while others remain in a monodomain configuration. An
analysis of the electrostatic potential reveals preferential points of pinning

710.1517 | Lattice QCD with two light Wilson quarks and maximally twisted mass | We summarise status and recent results of the European Twisted Mass
collaboration (ETMC). The collaboration has generated gauge configurations for
three different values of the lattice spacing smaller or equal 0.1 fm and
values of the charged pseudo scalar mass as low as 300 MeV with two flavours of
maximally twisted mass quarks. We provide evidence that O(a) improvement works
very well with maximally twisted mass fermions and that also higher order
lattice artifacts appear to be small. The currently only quantity in the light
meson and baryon sector where cut-off effects are visible is the neutral pseudo
scalar meson mass and we present an attempt to understand this from a
theoretical point of view.
We describe finite size effects and quark mass dependence of the mass and
decay constant of the (charged) pseudo scalar meson with chiral perturbation
theory formulae and our current estimate for the low energy constants l_{3,4}

710.1519 | Strong Approximations of BSDEs in a domain | We study the strong approximation of a Backward SDE with finite stopping time
horizon, namely the first exit time of a forward SDE from a cylindrical domain.
We use the Euler scheme approach of Bouchard and Touzi, Zhang 04}. When the
domain is piecewise smooth and under a non-characteristic boundary condition,
we show that the associated strong error is at most of order $h^{\frac14-\eps}$
where $h$ denotes the time step and $\eps$ is any positive parameter. This rate
corresponds to the strong exit time approximation. It is improved to
$h^{\frac12-\eps}$ when the exit time can be exactly simulated or for a weaker

710.1522 | Distributed spatial multiplexing with 1-bit feedback | We analyze a slow-fading interference network with MN non-cooperating
single-antenna sources and M non-cooperating single-antenna destinations. In
particular, we assume that the sources are divided into M mutually exclusive
groups of N sources each, every group is dedicated to transmit a common message
to a unique destination, all transmissions occur concurrently and in the same
frequency band and a dedicated 1-bit broadcast feedback channel from each
destination to its corresponding group of sources exists. We provide a
feedback-based iterative distributed (multi-user) beamforming algorithm, which
"learns" the channels between each group of sources and its assigned
destination. This algorithm is a straightforward generalization, to the
multi-user case, of the feedback-based iterative distributed beamforming
algorithm proposed recently by Mudumbai et al., in IEEE Trans. Inf. Th.
(submitted) for networks with a single group of sources and a single
destination. Putting the algorithm into a Markov chain context, we provide a
simple convergence proof. We then show that, for M finite and N approaching
infinity, spatial multiplexing based on the beamforming weights produced by the
algorithm achieves full spatial multiplexing gain of M and full per-stream
array gain of N, provided the time spent "learning'' the channels scales
linearly in N. The network is furthermore shown to "crystallize''. Finally, we
characterize the corresponding crystallization rate.
| cs.IT math.IT | we analyze a slowfading interference network with mn noncooperating singleantenna sources and m noncooperating singleantenna destinations in particular we assume that the sources are divided into m mutually exclusive groups of n sources each every group is dedicated to transmit a common message to a unique destination all transmissions occur concurrently and in the same frequency band and a dedicated 1bit broadcast feedback channel from each destination to its corresponding group of sources exists we provide a feedbackbased iterative distributed multiuser beamforming algorithm

710.1523 | Extracting the CKM phase angle \gamma(\equiv \phi_3) from isospin
analysis in B\to K \pi decays | We propose a new method to extract the CKM phase angle \gamma (\equiv \phi_3)
from the isospin analysis in B \to K \pi decays. Unlike previously proposed
methods, we do not employ flavor SU(3) symmetry, so that this method is free
from the hadronic uncertainty coming from the SU(3) breaking effect. Neither we
adopt any Dalitz-plot analysis, which may involve multiple strong phases and
large final state interactions. After including small CP violating terms in B^+
\to K^0 \pi^+ and color-suppressed electroweak penguin contribution in B^0 \to
K^+ \pi^-, whose values are estimated from the QCD factorization, we obtain
\gamma = ({70}^{+5 +1 +2}_{-14 -1 -3})^\circ \textrm{or} {106^\circ}< \gamma <
{180^\circ}. The first error is due to the experimental errors mainly caused by
mixing-induced CP asymmetry S_{{K_s} \pi^0}. The second and third errors come
from the theoretical uncertainty for two above-mentioned small contributions,
respectively. Since we utilize only the isospin relations in B \to K \pi
decays, this method will work well, regardless of possible new physics effects
unless the isospin relations do not hold.

710.1525 | Efficient Optimally Lazy Algorithms for Minimal-Interval Semantics | Minimal-interval semantics associates with each query over a document a set
of intervals, called witnesses, that are incomparable with respect to inclusion
(i.e., they form an antichain): witnesses define the minimal regions of the
document satisfying the query. Minimal-interval semantics makes it easy to
define and compute several sophisticated proximity operators, provides snippets
for user presentation, and can be used to rank documents. In this paper we
provide algorithms for computing conjunction and disjunction that are linear in
the number of intervals and logarithmic in the number of operands; for
additional operators, such as ordered conjunction and Brouwerian difference, we
provide linear algorithms. In all cases, space is linear in the number of
operands. More importantly, we define a formal notion of optimal laziness, and
either prove it, or prove its impossibility, for each algorithm. We cast our
results in a general framework of antichains of intervals on total orders,
making our algorithms directly applicable to other domains.

710.1528 | The energy release--stellar angular momentum independence in rotating
compact stars undergoing first-order phase transitions | We present the general relativistic calculation of the energy release
associated with a first order phase transition (PT) at the center of a rotating
neutron star (NS). The energy release, E_rel, is equal to the difference in
mass-energies between the initial (normal) phase configuration and the final
configuration containing a superdense matter core, assuming constant total
baryon number and the angular momentum. The calculations are performed with the
use of precise pseudo-spectral 2-D numerical code; the polytropic equations of
state (EOS) as well as realistic EOSs (Skyrme interactions, Mean Field Theory
kaon condensate) are used. The results are obtained for a broad range of
metastability of initial configuration and size of the new superdense phase
core in the final configuration. For a fixed ``overpressure'', dP, defined as
the relative excess of central pressure of a collapsing metastable star over
the pressure of the equilibrium first-order PT, the energy release up to
numerical accuracy does not depend on the stellar angular momentum and
coincides with that for nonrotating stars with the same dP. When the equatorial
radius of the superdense phase core is much smaller than the equatorial radius
of the star, analytical expressions for the E_rel can be obtained: E_rel is
proportional to dP^2.5 for small dP. At higher dP, the results of 1-D
calculations of E_rel(dP) for non-rotating stars reproduce with very high
precision exact 2-D results for fast-rotating stars. The energy release-angular
momentum independence for a given overpressure holds also for the so-called
``strong'' PTs (that destabilise the star against the axi-symmetric
perturbations), as well as for PTs with ``jumping'' over the energy barrier.

710.1529 | Optimum bias for fast-switching free energy calculations | We derive the bias function that minimizes the statistical error of free
energy differences calculated in work-biased fast-switching simulations. The
optimum bias function is compared to other bias functions using a particle
pulled through a viscous fluid as an illustrative example. Our analysis

710.153 | Canonical Forms for Unitary Congruence and *Congruence | We use methods of the general theory of congruence and *congruence for
complex matrices--regularization and cosquares-to determine a unitary
congruence canonical form (respectively, a unitary *congruence canonical form)
for complex matrices A such that \bar{A}A (respectively, A^2) is normal.
As special cases of our canonical forms, we obtain-in a coherent and
systematic way-known canonical forms for conjugate normal, congruence normal,
coninvolutory, involutory, projection, and unitary matrices. But we also obtain
canonical forms for matrices whose squares are Hermitian or normal, and other
cases that do not seem to have been investigated previously.
We show that the classification problems under (a) unitary *congruence when
A^3 is normal, and (b) unitary congruence when A\bar{A}A is normal, are both
unitarily wild, so there is no reasonable hope that a simple solution to them
can be found.

710.1531 | Far-Ultraviolet Cooling Features of the Antlia Supernova Remnant | We present far-ultraviolet observations of the Antlia supernova remnant
obtained with Far-ultraviolet IMaging Spectrograph (FIMS, also called SPEAR).
The strongest lines observed are C IV 1548,1551 and C III 977. The C IV
emission of this mixed-morphology supernova remnant shows a clumpy
distribution, and the line intensity is nearly constant with radius. The C III
977 line, though too weak to be mapped over the whole remnant, is shown to vary
radially. The line intensity peaks at about half the radius, and drops at the
edge of the remnant. Both the clumpy distribution of C IV and the rise in the C
IV to C III ratio towards the edge suggest that central emission is from

710.1532 | A step towards the Analysis of the Influence of an electrical Field on
the Propagation of Light | It is a matter of common knowledge that the field of gravitation influences
the propagation of light, but the question to which extent electromagnetic
fields do something similar is not completely answered. The birefringence
caused by electric and magnetic fields is subject of several articles in
Quantumelectrodynamics, but the absolute refractive index is discussed rather
rarely.
Some hypothetical considerations about the feasibility of an experiment to
analyze the refractive index in electromagnetic fields were given in a former
article by the same author. A first experimental test is reported now. Perhaps
an evidence for an influence of an electric field on the refractive index was
found, but the result is not reliable enough to claim already, that the
influence was seen - but it should encourage to perform further measurements
with different methods of higher precision.

710.1533 | Determination of the running coupling in pure SU(4) Yang-Mills theory | The Schrodinger functional is used to define a renormalised coupling for pure
SU(4) Yang-Mills theory, with Wilson action and suitably selected boundary
conditions on the link field. The coupling, which runs with the size of the
lattice, is then determined by a finite-size scaling technique through a large
range of momenta, thereby allowing a connection to be made between the high
energy regime and the low energy non-perturbative regime, where contact is made
with the physical scale of the theory. Using data from previous SU(2) and SU(3)
simulations obtained with the same technique, the running of the 't Hooft
coupling defined through the Schrodinger functional is studied, and we check
whether the large-N expectation that g^2*N is a universal function of the
energy scale E holds down to energies of the order of the string tension.

710.1535 | Charmonium dynamics in heavy ion collisions | Applying the HSD transport approach to charmonium dynamics within the
'hadronic comover model' and the 'QGP melting scenario', we show that the
suppression pattern seen at RHIC cannot be explained by the interaction with
baryons, comoving mesons and/or by color screening mechanism. The interaction
with hadrons in the late stages of the collision (when the energy density falls
below the critical) gives a sizable contribution to the suppression. On the
other hand, it does not account for the observed additional charmonium
dissociation and its dependence on rapidity. Together with the failure of the
hadron-string models to reproduce high v2 of open charm mesons, this suggests

710.1536 | First CNGS events detected by LVD | The CERN Neutrino to Gran Sasso (CNGS) project aims to produce a high energy,
wide band $\nu_{\mu}$ beam at CERN and send it toward the INFN Gran Sasso
National Laboratory (LNGS), 732 km away. Its main goal is the observation of
the $\nu_{\tau}$ appearance, through neutrino flavour oscillation. The beam
started its operation in August 2006 for about 12 days: a total amount of
$7.6~10^{17}$ protons were delivered to the target. The LVD detector, installed
in hall A of the LNGS and mainly dedicated to the study of supernova neutrinos,
was fully operating during the whole CNGS running time. A total number of 569
events were detected in coincidence with the beam spill time. This is in good
agreement with the expected number of events from Montecarlo simulations.

710.1537 | Simultaneous H.E.S.S. and Chandra observations of Sgr A* during an X-ray
flare | The rapidly varying non-thermal X-ray emission observed from Sgr A* points to
particle acceleration taking place close to the supermassive black hole. The
TeV gamma-ray source HESS J1745-290 is coincident with Sgr A* and may be
closely related to the X-ray emission. Simultaneous X-ray and TeV observations
are required to elucidate the relationship between these two objects. Here we
report on joint H.E.S.S./Chandra observations in July 2005, during which an
X-ray flare was detected. Despite a factor >10 increase in the X-ray flux of
Sgr A*, no evidence is found for an increase in the TeV gamma-ray flux. We find
that an increase of the gamma-ray flux of a factor 2 or greater can be excluded

710.1539 | Theoretical and experimental \alpha decay half-lives of the heaviest
odd-Z elements and general predictions | Theoretical decay half-lives of the heaviest odd-Z nuclei are calculated
using the experimental Q value. The barriers in the quasimolecular shape path
are determined within a Generalized Liquid Drop Model (GLDM) and the WKB
approximation is used. The results are compared with calculations using the
Density-Dependent M3Y (DDM3Y) effective interaction and the
Viola-Seaborg-Sobiczewski (VSS) formulas. The calculations provide consistent
estimates for the half-lives of the decay chains of these superheavy elements.
The experimental data stand between the GLDM calculations and VSS ones in the
most time. Predictions are provided for the decay half-lives of other
superheavy nuclei within the GLDM and VSS approaches using the recent

710.154 | Jet quenching parameter \hat q in the stochastic QCD vacuum with Landau
damping | We argue that the radiative energy loss of a parton traversing the
quark-gluon plasma is determined by Landau damping of soft modes in the plasma.
Using this idea, we calculate the jet quenching parameter of a gluon. The
calculation is done in SU(3) quenched QCD within the stochastic vacuum model.
At the LHC-relevant temperatures, the result depends on the gluon condensate,
the vacuum correlation length, and the gluon Debye mass. Numerically, when the
temperature varies from T=T_c to T=900 MeV, the jet quenching parameter rises
from \hat q=0 to approximately 1.8 GeV^2/fm. We compare our results with the
predictions of perturbative QCD and other calculations.

710.1541 | Constraints on Brane Inflation and Cosmic Strings | By considering simple, but representative, models of brane inflation from a
single brane-antibrane pair in the slow roll regime, we provide constraints on
the parameters of the theory imposed by measurements of the CMB anisotropies by
WMAP including a cosmic string component. We find that inclusion of the string
component is critical in constraining parameters. In the most general model
studied, which includes an inflaton mass term, as well as the brane-antibrane
attraction, values n_s < 1.02 are compatible with the data at 95 % confidence
level. We are also able to constrain the volume of internal manifold (modulo
factors dependent on the warp factor) and the value of the inflaton field to be
less than 0.66M_P at horizon exit. We also investigate models with a mass term.
These observational considerations suggest that such models have r < 2*10^-5,
which can only be circumvented in the fast roll regime, or by increasing the
number of antibranes. Such a value of r would not be detectable in CMB
polarization experiment likely in the near future, but the B-mode signal from
the cosmic strings could be detectable. We present forecasts of what a similar
analysis using PLANCK data would yield and find that it should be possible to
rule out G\mu > 6.5*10^-8 using just the TT, TE and EE power spectra.

710.1542 | The initial-final mass relationship from white dwarfs in common proper
motion pairs | The initial-final mass relationship of white dwarfs, which is poorly
constrained, is of paramount importance for different aspects in modern
astrophysics. From an observational perspective, most of the studies up to now
have been done using white dwarfs in open clusters. In order to improve the
initial-final mass relationship we explore the possibility of deriving a
semi-empirical relation studying white dwarfs in common proper motion pairs. We
have acquired long-slit spectra of the white dwarf members of the selected
common proper motion pairs, as well as high resolution spectra of their
companions. From these observations, a full analysis of the two members of each
common proper motion pair has lead to the initial and final masses of the white
dwarfs. These observations have allowed us to provide updated information for
the white dwarfs, since some of them were misclassified. This work is the first
one in using common proper motion pairs to improve the initial-final mass
relationship, and has also allowed to cover the poorly explored low-mass
domain. As in the case of studies based on white dwarfs in open clusters, the
distribution of the semi-empirical data presents a large scatter, which is
higher than the expected uncertainties in the derived values. This suggests
that the initial-final mass relationship may not be a single-valued function.

710.1544 | On the projective geometry of the supercircle: a unified construction of
the super cross-ratio and Schwarzian derivative | We consider the standard contact structure on the supercircle, S^{1|1}, and
the supergroups E(1|1), Aff(1|1) and SpO(2|1) of contactomorphisms, defining
the Euclidean, affine and projective geometry respectively. Using the new
notion of (p|q)-transitivity, we construct in synthetic fashion even and odd
invariants characterizing each geometry, and obtain an even and an odd super
cross-ratios. Starting from the even invariants, we derive, using a superized
Cartan formula, one-cocycles of the group of contactomorphisms, K(1), with
values in tensor densities F_\lambda(S^{1|1}). The even cross-ratio yields a
K(1) one-cocycle with values in quadratic differentials, Q(S^{1|1}), whose
projection on F_{3/2}(S^{1|1}) corresponds to the super Schwarzian derivative
arising in superconformal field theory. This leads to the classification of the
cohomology spaces H^1(K(1),F_\lambda(S^{1|1})). The construction is extended to
the case of S^{1|N}. All previous invariants admit a prolongation for N>1, as
well as the associated Euclidean and affine cocycles. The super Schwarzian
derivative is obtained from the even cross-ratio, for N=2, as a projection to
F_1(S^{1|2}) of a K(2) one-cocycle with values in Q(S^{1|2}). The obstruction

710.1545 | Radiative and isospin-violating decays of Ds mesons in the hadrogenesis
conjecture | The masses and decays of the scalar D_{s0}^*(2317) and axial-vector
D_{s1}^*(2460) charmed strange mesons are calculated consistently in the
hadrogenesis conjecture. These mesons decay either strongly into the
isospin-violating pi^0 D_s and pi^0 D_s^* channels or electromagnetically. They
are generated by coupled-channel dynamics based on the leading order chiral
Lagrangian. The effect of chiral corrections to chiral order Q_\chi^2 is
investigated. We show that taking into account large-N_c relations to determine
the strength of these correction terms implies a measurable signal for an
exotic axial-vector state in the eta D* invariant mass distribution. The
one-loop contribution to the electromagnetic decay amplitudes of scalar and
axial-vector states is calculated. The Lagrangian describing electromagnetic
interactions is obtained by gauging the chiral Lagrangian for hadronic
interactions and adding gauge-invariant correction terms to chiral order
Q_chi^2. In addition the role of light vector meson degrees of freedom is
explored. We confront our results with measured branching ratios. Once the
light vector mesons are included, a natural explanation of all radiative decay
parameters is achieved.

710.1546 | Hydrostatic pressure effects on the electrical transport properties of
Pr0.5Sr0.5MnO3 | We studied single-crystalline Pr0.5Sr0.5MnO3 by means of measurements of
magnetic susceptibility and specific heat at ambient pressure (P), and
electrical resistivity (r) in hydrostatic pressures up to 2 GPa. This material
displays ferromagnetic (FM) order, with Curie temperature TC ~ 255 K. A
crystallographic transformation from I4/mcm to Fmmm is accompanied by the onset
of antiferromagnetism (AFM), with Neel temperature TN ~ 161 K. The effect of
pressure is to lower TC, and raise TN at the approximate rates of -3.2 K/GPa,
and 14.2 K/GPa, respectively. Although the value of TN increases with P, due to
the enhancement of the superexchange interactions, the AFM-Fmmm state is
progressively suppressed, as pressure stabilizes the FM-I4/mcm phase to lower

710.1547 | Space cowboys odyssey: beyond the Gould Belt | We present our new advanced model for population synthesis of close-by
cooling NSs. Detailed treatment of the initial spatial distribution of NS
progenitors and a detailed ISM structure up to 3 kpc give us an opportunity to
discuss the strategy to look for new isolated cooling NSs. Our main results in
this respect are the following: new candidates are expected to be identified
behind the Gould Belt, in directions to rich OB associations, in particular in
the Cygnus-Cepheus region; new candidates, on average, are expected to be
hotter than the known population of cooling NS. Besides the usual approach
(looking for soft X-ray sources), the search in 'empty' $\gamma$-ray error
boxes or among run-away OB stars may yield new X-ray thermally emitting NS
candidates.

710.1548 | Propagation and interaction of chiral states in quantum gravity | We study the stability, propagation and interactions of braid states in
models of quantum gravity in which the states are four-valent spin networks
embedded in a topological three manifold and the evolution moves are given by
the dual Pachner moves. There are results for both the framed and unframed
case. We study simple braids made up of two nodes which share three edges,
which are possibly braided and twisted. We find three classes of such braids,

710.155 | VLT Spectroscopy of Globular Clusters in Low Surface Brightness Dwarf
Galaxies | We present VLT/FORS2 spectroscopic observations of globular clusters (GCs) in
five low surface brightness (LSB) dwarf galaxies: KK211 and KK221, which are
both dwarf spheroidal satellites (dSph) of NGC 5128, dSph KK84 located close to
the isolated S0 galaxy NGC 3115, and two isolated dwarf irregular (dIrr)
galaxies UGC 3755 and ESO 490-17. Our sample is selected from the Sharina et
al. (2005) database of Hubble Space Telescope WFPC2 photometry of GC candidates
in dwarf galaxies. For objects with accurate radial velocity measurements we
confirm 26 as genuine GCs out of the 27 selected candidates from our WFPC2
survey. Lick absorption line indices in the spectra of confirmed GCs and the
subsequent comparison with SSP model predictions show that all confirmed GCs in
dSphs are old, except GC KK211-3-149 (6 +/- 2 Gyr), which we consider to be the
nucleus of KK211. GCs in UGC 3755 and ESO 490-17 show a large spread in ages
ranging from old objects (t > 10 Gyr) to clusters with ages around 1 Gyr. Most
of our sample GCs have low metallicities [Z/H] <= -1. Two relatively metal-rich
clusters with [Z/H] ~ -0.3 are likely to be associated with NGC 3115. Our
sample GCs show in general a complex distribution of alpha-element enhancement
with a mean [alpha/Fe]=0.19 +/-0.04 derived with the chi2 minimization
technique and 0.18+/-0.12 dex computed with the iterative approach. These
values are slightly lower than the mean [alpha/Fe]=0.29+/-0.01 for typical
Milky Way GCs. We compare other abundance ratios with those of Local Group GCs
and find indications for systematic differences in N and Ca abundance. The
specific frequencies, S_N, of our sample galaxies are in line with the
predictions of a simple mass-loss model for dwarf galaxies and compare well
with S_N values found for dwarf galaxies in nearby galaxy clusters.

710.1551 | The Inductive Kernels of Graphs | It is well known that kernels in graphs are powerful and useful structures,
for instance in the theory of games. However, a kernel does not always exist
and Chv\'atal proved in 1973 that it is an NP-Complete problem to decide its
existence. We present here an alternative definition of kernels that uses an
inductive machinery : the inductive kernels. We prove that inductive kernels
always exist and a particular one can be constructed in quadratic time.
However, it is an NP-Complete problem to decide the existence of an inductive
kernel including (resp. excluding) some fixed vertex.
