710.0953 | The AGB stars of the intermediate-age LMC cluster NGC 1846 Variability
and age determination | Aims: To investigate variability and to model the pulsational behaviour of
AGB variables in the intermediate-age LMC cluster NGC 1846.
Methods: Our own photometric monitoring has been combined with data from the
MACHO archive to detect 22 variables among the cluster's AGB stars and to
derive pulsation periods. According to the global parameters of the cluster we
construct pulsation models taking into account the effect of the C/O ratio on
the atmospheric structure. In particular, we have used opacities appropriate
for both O-rich stars and carbon stars in the pulsation calculations.
Results: The observed P-L-diagram of NGC 1846 can be fitted using a mass of
the AGB stars of about 1.8 M$_{\sun}$. We show that the period of pulsation is
increased when an AGB star turns into a carbon star. Using the mass on the AGB
defined by the pulsational behaviour of our sample we derive a cluster age of
$1.4\times10^{9}$ years. This is the first time the age of a cluster has been
derived from the variability of its AGB stars. The carbon stars are shown to be
a mixture of fundamental and first overtone radial pulsators.

710.0955 | The XMM-Newton bright serendipitous survey. Identification and optical
spectral properties | AIMS: We present the optical classification and redshift of 348 X-ray
selected sources from the XMM-Newton Bright Serendipitous Survey (XBS) which
contains a total of 400 objects (identification level = 87%). About 240 are new
identifications. In particular, we discuss in detail the classification
criteria adopted for the Active Galactic Nuclei population.
METHODS: By means of systematic spectroscopic campaigns and through the
literature search we have collected an optical spectrum for the large majority
of the sources in the XBS survey and applied a well-defined classification
``flow-chart''.
RESULTS: We find that the AGN represent the most numerous population at the
flux limit of the XBS survey (~10^-13 erg cm^-2 s^-1) constituting 80% of the
XBS sources selected in the 0.5-4.5 keV energy band and 95% of the ``hard''
(4.5-7.5 keV) selected objects. Galactic sources populate significantly the
0.5-4.5 keV sample (17%) and only marginally (3%) the 4.5-7.5 keV sample. The
remaining sources in both samples are clusters/groups of galaxies and normal
galaxies (i.e. probably not powered by an AGN). Furthermore, the percentage of
type2 AGN (i.e. optically absorbed AGNs with A_V>2mag) dramatically increases
going from the 0.5-4.5 keV sample (f=N_AGN2/N_AGN=7%) to the 4.5-7.5 keV sample
(f=32%). We finally propose two simple diagnostic plots that can be easily used
to obtain the spectral classification for relatively low redshift AGNs even if
the quality of the spectrum is not good.

710.0956 | Second Law of Thermodynamics with Discrete Quantum Feedback Control | A new thermodynamic inequality is derived which leads to the maximum work
that can be extracted from multi-heat baths with the assistance of discrete
quantum feedback control. The maximum work is determined by the free-energy
difference and a generalized mutual information content between the
thermodynamic system and the feedback controller. This maximum work can exceed
that in conventional thermodynamics and, in the case of a heat cycle with two
heat baths, the heat efficiency can be greater than that of the Carnot cycle.
The consistency of our results with the second law of thermodynamics is ensured
by the fact that work is needed for information processing of the feedback
controller.

710.0957 | A Defective Graphene Phase Predicted to be a Room Temperature
Ferromagnetic Semiconductor | Theoretical calculations, based on hybrid exchange density functional theory,
are used to show that in graphene a periodic array of defects generates a
ferromagnetic ground state at room temperature for unexpectedly large defect
separations. This is demonstrated for defects that consist of a carbon vacancy
in which two of the dangling bonds are saturated with H atoms. The magnetic
coupling mechanism is analysed and found to be due to an instability in the
$\pi$ electron system with respect to a long-range spin polarisation
characterised by alternation in the spin direction between adjacent carbon
atoms. The disruption of the $\pi$-bonding opens a semiconducting gap at the
Fermi edge. The size of the energy gap and the magnetic coupling strength are
strong functions of the defect separation and can thus be controlled by varying
the defect concentration. The position of the semiconducting energy gap and the
electron effective mass are strongly spin-dependent and this is expected to
result in a spin asymmetry in the transport properties of the system. A
defective graphene sheet is therefore a very promising material with an
in-built mechanism for tailoring the properties of the spintronic devices of
the future.

710.0958 | Response Theory for Equilibrium and Non-Equilibrium Statistical
Mechanics: Causality and Generalized Kramers-Kronig relations | We consider the general response theory proposed by Ruelle for describing the
impact of small perturbations to the non-equilibrium steady states resulting
from Axiom A dynamical systems. We show that the causality of the response
functions allows for writing a set of Kramers-Kronig relations for the
corresponding susceptibilities at all orders of nonlinearity. Nonetheless, only
a special class of observable susceptibilities obey Kramers-Kronig relations.
Specific results are provided for arbitrary order harmonic response, which
allows for a very comprehensive Kramers-Kronig analysis and the establishment
of sum rules connecting the asymptotic behavior of the susceptibility to the
short-time response of the system. These results generalize previous findings
on optical Hamiltonian systems and simple mechanical models, and shed light on
the general impact of considering the principle of causality for testing
self-consistency: the described dispersion relations constitute unavoidable
benchmarks for any experimental and model generated dataset. In order to
connect the response theory for equilibrium and non equilibrium systems, we
rewrite the classical results by Kubo so that response functions formally
identical to those proposed by Ruelle, apart from the measure involved in the
phase space integration, are obtained. We briefly discuss how these results,
taking into account the chaotic hypothesis, might be relevant for climate
research. In particular, whereas the fluctuation-dissipation theorem does not
work for non-equilibrium systems, because of the non-equivalence between
internal and external fluctuations, Kramers-Kronig relations might be more
robust tools for the definition of a self-consistent theory of climate change.

nonequilibrium steady states resulting from axiom a dynamical systems we show that the causality of the response functions allows for writing a set of kramerskronig relations for the corresponding susceptibilities at all orders of nonlinearity nonetheless only a special class of observable susceptibilities obey kramerskronig relations specific results are provided for arbitrary order harmonic response which allows for a very comprehensive kramerskronig analysis and the establishment of sum rules connecting the asymptotic behavior of the susceptibility to the shorttime response of the system these results generalize previous findings on optical hamiltonian systems and simple mechanical models and shed light on the general impact of considering the principle of causality for testing selfconsistency the described dispersion relations constitute unavoidable benchmarks for any experimental and model generated dataset in order to connect the response theory for equilibrium and non equilibrium systems we rewrite the classical results by kubo so that response functions formally identical to those proposed by ruelle apart from the measure involved in the phase space integration are obtained we briefly discuss how these results taking into account the chaotic hypothesis might be relevant for climate research in particular whereas the fluctuationdissipation theorem does not work for nonequilibrium systems because of the nonequivalence between internal and external fluctuations kramerskronig relations might be more robust tools for the definition of a selfconsistent

710.0959 | Fermion pair production in planar Coulomb and Aharonov--Bohm potentials | Exact analytic solutions are found for the Dirac equation in 2+1 dimensions
for a spin-one-half particle in a combination of the Lorentz 3-vector and
scalar Coulomb as well as Aharonov--Bohm potentials. We employ the
two-component Dirac equation which contains a new parameter introduced by Hagen
to describe the spin of the spin-1/2 particle. We derive a transcendental
equations that implicitly determine the energy spectrum of an electron near the
negative-energy continuum boundary and the critical charges for some electron
states. Fermion pair production from a vacuum by a strong Coulomb field in the
presence of the magnetic flux tube of zero radius is considered. It is shown
that the presence of the Ahanorov--Bohm flux tends to stabilize the system.

710.0961 | Broad band X-ray spectroscopy of A0535+262 with SUZAKU | The transient X-ray binary pulsar A0535+262 was observed with Suzaku on 2005
September 14 when the source was in the declining phase of the August-September
minor outburst. The ~103 s X-ray pulse profile was strongly energy dependent, a
double peaked profile at soft X-ray energy band (<3 keV) and a single peaked
smooth profile at hard X-rays. The width of the primary dip is found to be
increasing with energy. The broad-band energy spectrum of the pulsar is well
described with a Negative and Positive power-law with EXponential (NPEX)
continuum model along with a blackbody component for soft excess. A weak iron
K_alpha emission line with an equivalent width ~25 eV was detected in the
source spectrum. The blackbody component is found to be pulsating over the
pulse phase implying the accretion column and/or the inner edge of the
accretion disk may be the possible emission site of the soft excess in
A0535+262. The higher value of the column density is believed to be the cause
of the secondary dip at the soft X-ray energy band. The iron line equivalent
width is found to be constant (within errors) over the pulse phase. However, a
sinusoidal type of flux variation of iron emission line, in phase with the hard
X-ray flux suggests that the inner accretion disk is the possible emission
region of the iron fluorescence line.

710.0964 | Ram pressure stripping the hot gaseous halos of galaxies in groups and
clusters | We use a large suite of carefully controlled full hydrodynamic simulations to
study the ram pressure stripping of the hot gaseous halos of galaxies as they
fall into massive groups and clusters. The sensitivity of the results to the
orbit, total galaxy mass, and galaxy structural properties is explored. For
typical structural and orbital parameters, we find that ~30% of the initial hot
galactic halo gas can remain in place after 10 Gyr. We propose a physically
simple analytic model that describes the stripping seen in the simulations
remarkably well. The model is analogous to the original formulation of Gunn &
Gott (1972), except that it is appropriate for the case of a spherical (hot)
gas distribution (as opposed to a face-on cold disk) and takes into account
that stripping is not instantaneous but occurs on a characteristic timescale.
The model reproduces the results of the simulations to within approximately 10%
at almost all times for all the orbits, mass ratios, and galaxy structural
properties we have explored. The one exception involves unlikely systems where
the orbit of the galaxy is highly non-radial and its mass exceeds about 10% of
the group or cluster into which it is falling (in which case the model
under-predicts the stripping following pericentric passage). The proposed model
has several interesting applications, including modelling the ram pressure
stripping of both observed and cosmologically-simulated galaxies and as a way
to improve current semi-analytic models of galaxy formation. One immediate
consequence is that the colours and morphologies of satellite galaxies in
groups and clusters will differ significantly from those predicted with the
standard assumption of complete stripping of the hot coronae.

710.0966 | Generalized virial theorem in f(R) gravity | We generalize the virial theorem in f(R) modified gravity using the
collisionless Boltzmann equation. We find supplementary geometric terms in the
modified Einstein equation providing an effective contribution to the
gravitational energy. The total virial mass is proportional to the effective
mass associated with the new geometrical term, which may account for the
well-known virial theorem mass discrepancy in clusters of galaxies. The model
predicts that the geometric mass and its effects extend beyond the virial
radius of the clusters. We also consider the behavior of the galaxy cluster
velocity dispersion in f(R) models. Thus, the f(R) virial theorem can be an
efficient tool in observationally testing the viability of this class of
generalized gravity models.

710.0968 | The modulation of the gamma-ray emission from the binary LS 5039 | Gamma-ray binaries, composed of a massive star and compact object, have been
established as a new class of sources of very high energy (VHE) photons. The
gamma-rays are produced by inverse Compton scattering of the stellar light by
VHE electrons accelerated in the vicinity of the compact object. The VHE
emission from LS 5039 displays an orbital modulation.
The inverse Compton spectrum depends on the angle between the incoming and
outgoing photon in the electron rest frame. Since the angle at which an
observer sees the star and electrons changes with the orbit, a phase dependence
of the spectrum is expected. The phase-dependent spectrum of LS 5039 is
calculated, assuming a continuous injection of electrons. The shape of the
electron distribution depends on the injected power-law and on the magnetic
field intensity.
Anisotropic scattering produces hard emission at inferior conjunction, when
attenuation due to pair production of the VHE gamma-rays on star light is
minimum. The computed lightcurve and spectra provide good fits to the HESS and
EGRET observations, except at phases of maximum attenuation where pair cascade
emission may be significant for HESS. Detailed predictions are made for a
modulation in the GLAST energy range. The magnetic field intensity at
periastron is 0.8+-0.2 G.
Anisotropic inverse Compton scattering plays a major role in LS 5039. The
derived magnetic field intensity, injection energy and slope suggest a
rotation-powered pulsar wind nebula. Gamma-ray binaries are promising sources
to study the environment of pulsars on small scales.

710.0969 | Quasi-Fuchsian AdS representations are Anosov | In a recent paper, Q. M\'erigot proved that representations in SO(2,n) of
uniform lattices of SO(1,n) which are Anosov in the sense of Labourie are
quasi-Fuchsian, i.e. are faithfull, discrete, and preserve an acausal subset in
the boundary of anti-de Sitter space. In the present paper, we prove the
reverse implication. It also includes: -- A construction of Dirichlet domains
in the context of anti-de Sitter geometry, -- A proof that spatially compact

710.0972 | A Floer homology for exact contact embeddings | In this paper we construct the Floer homology for an action functional which
was introduced by Rabinowitz and prove a vanishing theorem. As an application,
we show that there are no displaceable exact contact embeddings of the unit
cotangent bundle of a sphere of dimension greater than three into a convex
exact symplectic manifold with vanishing first Chern class. This generalizes

710.0975 | Renormalisation of quark bilinears with Nf=2 Wilson fermions and
tree-level improved gauge action | We present results for the renormalisation constants of bilinear quark
operators, using the Nf=2 twisted mass Wilson action at maximal twist (which
guarantees automatic O(a) improvement) and the tree-level Symanzik improved
gauge action. The scale-independent renormalisation constants are computed with
a new method, which makes use of both standard twisted mass and
Osterwalder-Seiler fermions. Moreover, the results from an RI-MOM calculation

710.0978 | QCD symmetries in excited hadrons | Recent developments for chiral and $U(1)_A$ restorations in excited hadrons
are reviewed. We emphasize predictions of the chiral symmetry restoration
scenario for axial charges and couplings to Goldstone bosons. Using very
general chiral symmetry arguments it is shown that strict chiral restoration in
a given excited nucleon forbids its decay into the $N \pi$ channel. We confront
this prediction with the $N^*N\pi$ coupling constants extracted from the decay
widths and observe a 100 % correlation of these data with the spectroscopic
parity doublet patterns. These results suggest that the lowest approximate
chiral parity doublet is the $N(1440) - N(1535)$ pair. In the meson sector we
discuss predictions of the chiral symmetry restoration for still missing states
and a signature of the higher symmetry observed in new $\bar p p$ data. We
conclude with the exactly solvable chirally symmetric and confining model that
can be considered as a generalization of the 1+1 dimensional 't Hooft model to

710.0979 | Three-Dimensional Observations of H_2 Emission around Sgr A East - I.
Structure in the Central 10 Parsecs of Our Galaxy | We have obtained velocity-resolved spectra of the H_2 v=1-0 S(1) (lambda =
2.1218 micron) emission line at 2 arcsec angular resolution (or 0.08 pc spatial
resolution) in four regions within the central 10 pc of the Galaxy where the
supernova-like remnant Sgr A East is colliding with molecular clouds. To
investigate the kinematic, physical, and positional relationships between the
important gaseous components in the center, we compared the H_2 data cube with
previously published NH_3 data. The projected interaction-boundary of Sgr A
East is determined to be an ellipse with its center offset 1.5 pc from Sgr A*
and dimensions of 10.8 pc X 7.6 pc. This H_2 boundary is larger than the
synchrotron emission shell but consistent with the dust ring which is believed
to trace the shock front of Sgr A East. Since Sgr A East is driving shocks into
its nearby molecular clouds, we can determine their positional relationships
using the shock directions as indicators. As a result, we suggest a revised
model for the three-dimensional structure of the central 10 pc. The actual
contact between Sgr A East and all of the surrounding molecular material,
including the circum-nuclear disk and the southern streamer, makes the
hypothesis of infall into the nucleus and feeding of Sgr A* very likely.

710.098 | Preparation of entangled states of two photons in several spatial modes | We describe a protocol capable of preparing an arbitrary state of two photons
in several spatial modes using pairs of photons generated by spontaneous
parametric down-conversion, linear optical elements and single-photon detectors
or post-selection. The protocol involves unitary and non-unitary
transformations realizable by beam splitters and phase shifters. Non-unitary
transformations are implemented by attenuation filters. The protocol contains
several optimization capabilities with the goal of improving overall
probability of its success. We also show how entangled two-photon states

710.0981 | Illuminating the 1/x moment of parton distribution functions | The Weisberger relation, an exact statement of the parton model, elegantly
relates a high-energy physics observable, the 1/x moment of parton distribution
functions, to a nonperturbative low-energy observable: the dependence of the
nucleon mass on the value of the quark mass or its corresponding quark
condensate. We show that contemporary fits to nucleon structure functions fail
to determine this 1/x moment; however, deeply virtual Compton scattering can be
described in terms of a novel F_{1/x}(t) form factor which illuminates this
physics. An analysis of exclusive photon-induced processes in terms of the
parton-nucleon scattering amplitude with Regge behavior reveals a failure of
the high Q^2 factorization of exclusive processes at low t in terms of the
Generalized Parton-Distribution Functions which has been widely believed to
hold in the past. We emphasize the need for more data for the DVCS process at
large t in future or upgraded facilities.

710.0983 | Naked Singularities, Cosmic Time Machines and Impulsive Events | Continued gravitational collapse gives rise to curvature singularities. If a
curvature singularity is globally naked then the space-time may be causally
future ill-behaved admitting closed time-like or null curves which extend to
asymptotic distances and generate a Cosmic Time Machine (de Felice (1995)

710.0984 | Astrophysics with the AMS-02 experiment | The Alpha Magnetic Spectrometer (AMS), whose final version AMS-02 is to be
installed on the International Space Station (ISS) for at least 3 years, is a
detector designed to measure charged cosmic ray spectra with energies up to the
TeV region and with high energy photon detection capability up to a few hundred
GeV, using state-of-the-art particle identification techniques. Following the
successful flight of the detector prototype (AMS-01) aboard the space shuttle,
AMS-02 is expected to provide a significant improvement on the current
knowledge of the elemental and isotopic composition of hadronic cosmic rays due
to its long exposure time (minimum of 3 years) and large acceptance (0.5 m^2
sr) which will enable it to collect a total statistics of more than 10^10
nuclei. Detector capabilities for charge, velocity and mass identification,
estimated from ion beam tests and detailed Monte Carlo simulations, are
presented. Relevant issues in cosmic ray astrophysics addressed by AMS-02,
including the test of cosmic ray propagation models, galactic confinement times
and the influence of solar cycles on the local cosmic ray flux, are briefly
discussed.

examined in an all-optical pump-probe setup. The frequency dependence on the
external field is used to extract the uniaxial in-plane anisotropy constant.
The damping shows a strong dependence on the frequency, but also on the laser

710.0988 | Confront Holographic QCD with Regge Trajectories of vectors and

type II superstring theory, and demonstrate the physical meaning of the
parameters characterizing the 5-dimension metric structure of the
\textit{holographic} QCD model by relating them to the parameters describing
Regge trajectories. By matching the spectra of vector mesons $\rho_1$ with
deformed $Dp-Dq$ soft-wall model, we find that the spectra of vector mesons
$\rho_1$ can be described very well in the soft-wall $D3-Dq$ model, i.e,
$AdS_5$ soft-wall model. We then investigate how well the $AdS_5$ soft-wall
model can describe the Regge trajectory of axial-vector mesons $a_1$. We find
that the constant component of the 5-dimension mass square of axial-vector
mesons plays an efficient role to realize the chiral symmetry breaking in the
vacuum, and a small negative $z^4$ correction in the 5-dimension mass square is
helpful to realize the chiral symmetry restoration in high excitation states.

710.0992 | Expectation values, experimental predictions, events and entropy in
quantum gravitationally decohered quantum mechanics | We restate Kay's 1998 hypothesis which simultaneously offers an objective
definition for the entropy of a closed system, a microscopic foundation for the
Second Law, a resolution of the Information Loss (and other) Black-Hole
Puzzle(s) and an objective mechanism for decoherence. Presupposing a
conventional unitary theory of low-energy quantum gravity, it offers all this
by taking the physical density operator of a closed system to be the partial
trace of its total density operator (assumed pure) over gravity and by defining
its physical entropy to be its `matter-gravity entanglement entropy'. We also
recall Kay's 1998 modified non-relativistic (many-body) quantum mechanics based
on Kay's hypothesis with a Newtonian approximation to quantum gravity. In this
modification, we find formal expectation values for certain `observables' such
as momentum-squared and Parity are altered but those for functions of positions
are unaltered. However, by arguing that every real measurement can ultimately
be taken to be a position measurement, we prove that, in practice, it is
impossible to detect any alteration at all and, in particular, we predict no
alteration for Roger Penrose's experiment. Nevertheless, Kay's modification
contains no Schr\"odinger Cat-like states, and also allows an `events'
interpretation which we tentatively propose and begin to explore. We also
obtain a Second-Law type result for a non-relativistic toy-model closed system
and argue that similar results will apply for a wide class of model Newtonian
and post-Newtonian closed systems although we argue that ordinary actual
lab-sized systems can never be treated as closed for the purpose of calculating
their entropy. Compared with `collapse models' such as GRW, Kay's Newtonian
theory does a similar job while being free from ad hoc assumptions.

resolution of the information loss and other blackhole puzzles and an objective mechanism for decoherence presupposing a conventional unitary theory of lowenergy quantum gravity it offers all this by taking the physical density operator of a closed system to be the partial trace of its total density operator assumed pure over gravity and by defining its physical entropy to be its mattergravity entanglement entropy we also recall kays 1998 modified nonrelativistic manybody quantum mechanics based on kays hypothesis with a newtonian approximation to quantum gravity in this modification we find formal expectation values for certain observables such as momentumsquared and parity are altered but those for functions of positions are unaltered however by arguing that every real measurement can ultimately be taken to be a position measurement we prove that in practice it is impossible to detect any alteration at all and in particular we predict no alteration for roger penroses experiment nevertheless kays modification contains no schrodinger catlike states and also allows an events interpretation which we tentatively propose and begin to explore we also obtain a secondlaw type result for a nonrelativistic toymodel closed system and argue that similar results will apply for a wide class of model newtonian and postnewtonian closed systems although we argue that ordinary actual labsized systems can never be treated as closed for the purpose of calculating their entropy compared with collapse models such as grw kays newtonian theory does a similar job while being free from ad

710.0993 | Particle identification with the AMS-02 RICH detector: search for dark
matter with antideuterons | The Alpha Magnetic Spectrometer (AMS), whose final version AMS-02 is to be
installed on the International Space Station (ISS) for at least 3 years, is a
detector designed to measure charged cosmic ray spectra with energies up to the
TeV region and with high energy photon detection capability up to a few hundred
GeV, using state-of-the art particle identification techniques. It is equipped
with several subsystems, one of which is a proximity focusing Ring Imaging
Cherenkov (RICH) detector equipped with a dual radiator (aerogel+NaF), a
lateral conical mirror and a detection plane made of 680 photomultipliers and
light guides, enabling precise measurements of particle electric charge and
velocity (Delta beta / beta ~ 10^-3 and 10^-4 for Z=1 and Z=10-20,
respectively) at kinetic energies of a few GeV/nucleon. Combining velocity
measurements with data on particle rigidity from the AMS-02 Tracker (Delta R /
R ~ 2% for R=1-10 GV) it is possible to obtain a reliable measurement for
particle mass. One of the main topics of the AMS-02 physics program is the
search for indirect signatures of dark matter. Experimental data indicate that
dark, non-baryonic matter of unknown composition is much more abundant than
baryonic matter, accounting for a large fraction of the energy content of the
Universe. Apart from antideuterons produced in cosmic-ray propagation, the
annihilation of dark matter will produce additional antideuteron fluxes.
Detailed Monte Carlo simulations of AMS-02 have been used to evaluate the
detector's performance for mass separation, a key issue for anti-D/anti-p
separation. Results of these studies are presented.

710.0994 | Improved determination of color-singlet nonrelativistic QCD matrix
elements for S-wave charmonium | We present a new computation of S-wave color-singlet nonrelativistic QCD
matrix elements for the J/psi and the eta_c. We compute the matrix elements of
leading order in the heavy-quark velocity v and the matrix elements of relative
order v^2. Our computation is based on the electromagnetic decay rates of the
J/psi and the eta_c and on a potential model that employs the Cornell
potential. We include relativistic corrections to the electromagnetic decay
rates, resumming a class of corrections to all orders in v, and find that they
significantly increase the values of the matrix elements of leading order in v.
This increase could have important implications for theoretical predictions for
a number of quarkonium decay and production processes. The values that we find
for the matrix elements of relative order v^2 are somewhat smaller than the

710.0995 | Resummation of Relativistic Corrections to e+ e- -> J/psi+eta_c | We present a new calculation, in the nonrelativistic QCD (NRQCD)
factorization formalism, of the relativistic corrections to the
double-charmonium cross section sigma[e+ e- -> J/psi+eta_c] at the energy of
the Belle and BABAR experiments. In comparison with previous work, our
calculation contains several refinements. These include the use of the improved
results for the nonperturbative NRQCD matrix elements, the resummation of a
class of relativistic corrections, the use of the vector-meson-dominance method
to calculate the fragmentation contribution to the pure QED amplitude, the
inclusion of the effects of the running of alpha, and the inclusion of the
contribution that arises from the interference between the relativistic
corrections and the corrections of next-to-leading order in alpha_s. We also
present a detailed estimate of the theoretical uncertainty. We conclude that
the discrepancy between the theoretical prediction for sigma[e+e- ->
J/psi+eta_c] and the experimental measurements has been resolved.

710.0996 | Intelligibility and First Passage Times In Complex Urban Networks | Topology of urban environments can be represented by means of graphs. We
explore the graph representations of several compact urban patterns by random
walks. The expected time of recurrence and the expected first passage time to a
node scales apparently linearly in all urban patterns we have studied In space
syntax theory, a positive relation between the local property of a node
(qualified by connectivity or by the recurrence time) and the global property
of the node (estimated in our approach by the first passage time to it) is
known as intelligibility. Our approach based on random walks allows to extend

Sigma vanishes in the chiral limit, we observe densities for the microscopic
Dirac spectrum, which have not been addressed yet by Random Matrix Theory

different topological sectors with chiral RMT in unitary ensemble we obtain --
for the very light fermion masses -- values for Sigma that follow closely the

710.0999 | Particle Production in an expanding universe dominated by dark energy
fluid | We investigate the fate of particle production in an expanding universe
dominated by a perfect fluid with equation of state $p = \alpha\rho$. The rate
of particle production, using the Bogolioubov coefficients, are determined
exactly for any value of $\alpha$ in the case of a flat universe. When the
strong energy condition is satisfied, the rate of particle production decreases
as time goes on, in agreement to the fact that the four-dimensional curvature
decreases with the expansion; the opposite occurs when the strong energy
condition is violated. In the phantomic case, the rate of particle production
diverges in a finite time. This may lead to a backreaction effect, leading to
the avoidance of the big rip singularity, specially if $- 1 > \alpha > -

710.1 | Electron-Positron Plasma Generation in a Magnetar Magnetosphere | We consider the electron-positron plasma generation processes in the
magnetospheres of magnetars - neutron stars with strong surface magnetic
fields, B = 10^(14) - 10^(15) G. We show that the photon splitting in a
magnetic field, which is effective at large field strengths, does not lead to
the suppression of plasma multiplication, but manifests itself in a high
polarization of gamma-ray photons. A high magnetic field strength does not give
rise to the second generation of particles produced by synchrotron photons.
However, the density of the first-generation particles produced by curvature
photons in the magnetospheres of magnetars can exceed the density of the same
particles in the magnetospheres of ordinary radio pulsars. The plasma
generation inefficiency can be attributed only to slow magnetar rotation, which
causes the energy range of the produced particles to narrow. We have found a
boundary in the P - Pdot diagram that defines the plasma generation threshold
in a magnetar magnetosphere.

710.1001 | Connectivity of Random 1-Dimensional Networks | An important problem in wireless sensor networks is to find the minimal
number of randomly deployed sensors making a network connected with a given
probability. In practice sensors are often deployed one by one along a
trajectory of a vehicle, so it is natural to assume that arbitrary probability
density functions of distances between successive sensors in a segment are
given. The paper computes the probability of connectivity and coverage of

710.1002 | Absence of gravitational contributions to the running Yang-Mills
coupling | The question of a modification of the running gauge coupling of (non-)
abelian gauge theories by an incorporation of the quantum gravity contribution
has recently attracted considerable interest. In this letter we perform an
involved diagrammatical calculation in the full Einstein-Yang-Mills system both
in cut-off and dimensional regularization at one loop order. It is found that
all gravitational quadratic divergencies cancel in cut-off regularization and
are trivially absent in dimensional regularization so that there is no
alteration to asymptotic freedom at high energies. The logarithmic divergencies
give rise to an extended effective Einstein-Yang-Mills Lagrangian with a
counterterm of dimension six. In the pure Yang-Mills sector this counterterm
can be removed by a nonlinear field redefinition of the gauge potential,
reproducing a classical result of Deser, Tsao and van Nieuwenhuizen obtained in
the background field method with dimensional regularization.

a beam splitter and a collimator of these electronic currents. The result is
demonstrated trough an optical analogy using two dimensional photonic crystals.

710.1005 | Black Hole Initial Data with a Horizon of Prescribed Geometry | The purpose of this work is to construct asymptotically flat, time symmetric
initial data with an apparent horizon of prescribed intrinsic geometry. To do
this, we use the parabolic partial differential equation for prescribing scalar
curvature. In this equation the horizon geometry is contained within the freely
specifiable part of the metric. This contrasts with the conformal method in
which the geometry of the horizon can only be specified up to a conformal
factor.

710.1007 | Two representation theorems of three-valued structures by means of
binary relations | The results here presented are a continuation of the algebraic research line
which attempts to find properties of multiple-valued systems based on a poset
of two agents.
The aim of this paper is to exhibit two relationships between some

710.1008 | Entanglement: A myth introducing non-locality in any quantum theory | The purposes of the present article are: a) To show that non-locality leads
to the transfer of certain amounts of energy and angular momentum at very long
distances, in an absolutely strange and unnatural manner, in any model
reproducing the quantum mechanical results. b) To prove that non-locality is
the result only of the zero spin state assumption for distant particles, which
explains its presence in any quantum mechanical model. c) To reintroduce
locality, simply by denying the existence of the zero spin state in nature (the
so-called highly correlated, or EPR singlet state) for particles
non-interacting with any known field. d) To propose a realizable experiment to
clarify if two remote (and thus non-interacting with a known field) particles,
supposed to be correlated as in Bell-type experiments, are actually in zero
spin state.

710.1009 | Magnetic phase diagrams of the Kagome staircase compound Co3V2O8 | At zero magnetic field, a series of five phase transitions occur in Co3V2O8.
The Neel temperature, TN=11.4 K, is followed by four additional phase changes
at T1=8.9 K, T2=7.0 K, T3=6.9 K, and T4=6.2 K. The different phases are
distinguished by the commensurability of the b-component of its spin density
wave vector. We investigate the stability of these various phases under
magnetic fields through dielectric constant and magnetic susceptibility
anomalies. The field-temperature phase diagram of Co3V2O8 is completely
resolved. The complexity of the phase diagram results from the competition of
different magnetic states with almost equal ground state energies due to
competing exchange interactions and frustration.

710.101 | Binaries at Low Metallicity: ranges for case A, B and C mass transfer | The evolution of single stars at low metallicity has attracted a large
interest, while the effect of metallicity on binary evolution remains still
relatively unexplored. We study the effect of metallicity on the number of
binary systems that undergo different cases of mass transfer. We find that
binaries at low metallicity are more likely to start transferring mass after
the onset of central helium burning, often referred to as case C mass transfer.
In other words, the donor star in a metal poor binary is more likely to have
formed a massive CO core before the onset of mass transfer.
At solar metallicity the range of initial binary separations that result in
case C evolution is very small for massive stars, because they do not expand
much after the ignition of helium and because mass loss from the system by
stellar winds causes the orbit to widen, preventing the primary star to fill
its Roche lobe. This effect is likely to have important consequences for the
metallicity dependence of the formation rate of various objects through binary
evolution channels, such as long GRBs, double neutron stars and double white
dwarfs.

710.1011 | Measurements of plasma motions in dynamic fibrils | We present a 40 minute time series of filtergrams from the red and the blue
wing of the \halpha line in an active region near the solar disk center. From
these filtergrams we construct both Dopplergrams and summed ``line center''
images. Several dynamic fibrils (DFs) are identified in the summed images. The
data is used to simultaneously measure the proper motion and the Doppler
signals in DFs. For calibration of the Doppler signals we use spatially
resolved spectrograms of a similar active region. Significant variations in the
calibration constant for different solar features are observed, and only
regions containing DFs have been used in order to reduce calibration errors. We
find a coherent behavior of the Doppler velocity and the proper motion which
clearly demonstrates that the evolution of DFs involve plasma motion. The
Doppler velocities are found to be a factor 2--3 smaller than velocities
derived form proper motions in the image plane. The difference can be explained
by the radiative processes involved, the Doppler velocity is a result of the
local atmospheric velocity weighted with the response function. As a result the
Doppler velocity originates from a wide range in heights in the atmosphere.
This is contrasted by the proper motion velocity which is measured from the
sharply defined bright tops of the DFs and is therefore a very local velocity
measure. The Doppler signal originates from well below the top of the DF.
Finally we discuss how this difference together with the lacking spatial
resolution of older observations have contributed to some of the confusion
about the identity of DFs, spicules and mottles.

710.1012 | Expansion dynamics of Lennard-Jones systems | The dynamics of the expansion of a Lennard-Jones system, initially confined
at high density and subsequently expanding freely in the vacuum, is confronted
to an expanding statistical ensemble, derived in the diluted quasi-ideal
Boltzmann approximation. The description proves to be fairly accurate at
predicting average one-body global observables, but important deviations are

710.1014 | Wealth distribution in a System with Wealth-limited Interactions | We model a closed economic system with interactions that generates the
features of empirical wealth distribution across all wealth brackets, namely a
Gibbsian trend in the lower and middle wealth range and a Pareto trend in the
higher range, by simply limiting the an agents' interaction to only agents with
nearly the same wealth. To do this, we introduce a parameter BETA that limits
the range on the wealth of a partner with which an agent is allowed to
interact. We show that this wealth-limited interaction is enough to distribute
wealth in a purely power law trend. If the interaction is not wealth limited,
the wealth distribution is expectedly Gibbsian. The value of BETA where the
transition from a purely Gibbsian law to a purely power law distribution
happens depends on whether the choice of interaction partner is mutual nor not.
For a non-mutual choice, where the richer agent gets to decide, the transition
happens at BETA=1.0. For a mutual choice, the transition is at BETA= 0.60. In
order to generate a mixed Gibbs-Pareto distribution, we apply another
wealth-based rule that depends on the parameter w_limit. An agent whose wealth
is below w_limit can choose any partner to interact with, while an agent whose
wealth is above w_limit is subject to the wealth-limited range in his choice of
partner. A Gibbs-Pareto distribution appears if both these wealth-based rules
are applied.

710.1015 | Concerning verification of the Nernst theorem for Casimir-Lifshitz free
energy | By regarding the Lifshitz expression for the Casimir free energy on the real
frequency axis rather than the imaginary Matsubara frequencies as is customary,
new light is shed on the ongoing debate regarding the thermodynamical
consistency of this theory in combination with common permittivity models. It
is argued that when permittivity is temperature independent over a temperature
interval including zero temperature, a cavity made of causal material with
continuous dispersion properties separated by vacuum cannot violate Nernst's
theorem (the third law of thermodynamics). The purported violation of this
theorem pertains to divergencies in the double limit in which frequency and
temperature vanish simultaneously. While any model should abide by the laws of
thermodynamics within its range of applicability, we emphasise that the Nernst
heat theorem is a relevant criterion for choosing amongst candidate theories
only when these theories are fully applicable at zero temperature and
frequency.

710.1017 | Morita theory of comodules over corings | By a theorem due to Kato and Ohtake, any (not necessarily strict) Morita
context induces an equivalence between appropriate subcategories of the module
categories of the two rings in the Morita context. These are in fact categories
of firm modules for non-unital subrings. We apply this result to various Morita
contexts associated to a comodule $\Sigma$ of an $A$-coring $\cC$. This allows
to extend (weak and strong) structure theorems in the literature, in particular
beyond the cases when any of the coring $\cC$ or the comodule $\Sigma$ is
finitely generated and projective as an $A$-module. That is, we obtain
relations between the category of $\cC$-comodules and the category of firm
modules for a firm ring $R$, which is an ideal of the endomorphism algebra
$^\cC(\Sigma)$. For a firmly projective comodule of a coseparable coring we

710.1018 | Probing the Neutral Fraction of the IGM with GRBs during the Epoch of
Reionization | We show that near-infrared observations of the red side of the Ly-alpha line
from a single gamma ray burst (GRB) afterglow cannot be used to constrain the
global neutral fraction of the intergalactic medium (IGM), x_H, at the GRB's
redshift to better than ~0.3. Some GRB sight-lines will encounter more neutral
hydrogen than others at fixed x_H owing to the patchiness of reionisation. GRBs
during the epoch of reionization will often bear no discernible signature of a
neutral IGM in their afterglow spectra. We discuss the constraints on x_H from
the z = 6.3 burst, GRB050904, and quantify the probability of detecting a
neutral IGM using future spectroscopic observations of high-redshift,
near-infrared GRB afterglows. Assuming an observation with signal-to-noise
similar to the Subaru FOCAS spectrum of GRB050904 and that the column density
distribution of damped Ly-alpha absorbers is the same as measured at lower
redshifts, a GRB from an epoch when x_H = 0.5 can be used to detect a partly
neutral IGM at 98% confidence level 10% of the time (and, for an observation
with three times the sensitivity, 30% of the time).

710.1021 | Avalanche dynamics of radio pulsar glitches | We test statistically the hypothesis that radio pulsar glitches result from
an avalanche process, in which angular momentum is transferred erratically from
the flywheel-like superfluid in the star to the slowly decelerating, solid
crust via spatially connected chains of local, impulsive, threshold-activated
events, so that the system fluctuates around a self-organised critical state.
Analysis of the glitch population (currently 285 events from 101 pulsars)
demonstrates that the size distribution in individual pulsars is consistent
with being scale invariant, as expected for an avalanche process. The
waiting-time distribution is consistent with being exponential in seven out of
nine pulsars where it can be measured reliably, after adjusting for
observational limits on the minimum waiting time, as for a constant-rate
Poisson process. PSR J0537$-$6910 and PSR J0835$-$4510 are the exceptions;
their waiting-time distributions show evidence of quasiperiodicity. In each
object, stationarity requires that the rate $\lambda$ equals $- \epsilon
\dot{\nu} / <\Delta\nu>$, where $\dot{\nu}$ is the angular acceleration of the
crust, $<\Delta\nu>$ is the mean glitch size, and $\epsilon\dot{\nu}$ is the
relative angular acceleration of the crust and superfluid. There is no evidence
that $\lambda$ changes monotonically with spin-down age. The rate distribution
itself is fitted reasonably well by an exponential for $\lambda \geq 0.25 {\rm
yr^{-1}}$. For $\lambda < 0.25 {\rm yr^{-1}}$, its exact form is unknown; the
exponential overestimates the number of glitching pulsars observed at low
$\lambda$, where the limited total observation time exercises a selection bias.

710.1022 | Conservative evaluation of the uncertainty in the LAGEOS-LAGEOS II
Lense-Thirring test | We deal with the test of the general relativistic gravitomagnetic
Lense-Thirring effect currently ongoing in the Earth's gravitational field with
the combined nodes \Omega of the laser-ranged geodetic satellites LAGEOS and
LAGEOS II.
One of the most important source of systematic uncertainty on the orbits of
the LAGEOS satellites, with respect to the Lense-Thirring signature, is the
bias due to the even zonal harmonic coefficients J_L of the multipolar
expansion of the Earth's geopotential which account for the departures from
sphericity of the terrestrial gravitational potential induced by the
centrifugal effects of its diurnal rotation. The issue addressed here is: are
the so far published evaluations of such a systematic error reliable and
realistic? The answer is negative. Indeed, if the difference \Delta J_L among
the even zonals estimated in different global solutions (EIGEN-GRACE02S,
EIGEN-CG03C, GGM02S, GGM03S, ITG-Grace02, ITG-Grace03s, JEM01-RL03B, EGM2008,
AIUB-GRACE01S) is assumed for the uncertainties \delta J_L instead of using
their more or less calibrated covariance sigmas \sigma_{J_L}, it turns out that
the systematic error \delta\mu in the Lense-Thirring measurement is about 3 to
4 times larger than in the evaluations so far published based on the use of the
sigmas of one model at a time separately, amounting up to 37% for the pair
EIGEN-GRACE02S/ITG-Grace03s. The comparison among the other recent GRACE-based
models yields bias as large as about 25-30%. The major discrepancies still
occur for J_4, J_6 and J_8, which are just the zonals the combined
LAGEOS/LAGOES II nodes are most sensitive to.

710.1023 | Scaling relations of the colour-detected cluster RzCS 052 at z=1.016 and
of some other high redshift clusters | We report on the discovery of the z=1.016 cluster RzCS 052 using a modified
red sequence method, followup spectroscopy and X-ray imaging. This cluster has
a velocity dispersion of 710+-150 km/s, a virial mass of 4.0e14 Msol (based on
21 spectroscopically confirmed members) and an X-ray luminosity of (0.68+-
0.47)e44 ergs/s in the [1-4] keV band. This optically selected cluster appears
to be of richness class 3 and to follow the known L_X-sigma_v relation for high
redshift X-ray selected clusters. Using these data, we find that the halo
occupation number for this cluster is only marginally consistent with what
expected assuming a self-similar evolution of cluster scaling relations,
suggesting perhaps a break of them at z~1. We also rule out a strong galaxy
merging activity between z=1 and today. Finally, we present a Bayesian approach
to measuring cluster velocity dispersions and X-ray luminosities in the
presence of a background: we critically reanalyze recent claims for X-ray
underluminous clusters using these techniques and find that the clusters can be
accommodated within the existing L_X -sigma_v relation.

monograph, Anick constructed such a fibration for p>= 5 and r>= 1. Using new
methods we give a much more conceptual construction which is also valid for p=3
and r>= 1. We go on to establish several properties of the space T.

710.1025 | Stability domains of actin genes and genomic evolution | In eukaryotic genes the protein coding sequence is split into several
fragments, the exons, separated by non-coding DNA stretches, the introns.
Prokaryotes do not have introns in their genome. We report the calculations of
stability domains of actin genes for various organisms in the animal, plant and
fungi kingdoms. Actin genes have been chosen because they have been highly
conserved during evolution. In these genes all introns were removed so as to
mimic ancient genes at the time of the early eukaryotic development, i.e.
before introns insertion. Common stability boundaries are found in evolutionary
distant organisms, which implies that these boundaries date from the early
origin of eukaryotes. In general boundaries correspond with introns positions
of vertebrates and other animals actins, but not much for plants and fungi. The
sharpest boundary is found in a locus where fungi, algae and animals have
introns in positions separated by one nucleotide only, which identifies a
hot-spot for insertion. These results suggest that some introns may have been
incorporated into the genomes through a thermodynamic driven mechanism, in
agreement with previous observations on human genes. They also suggest a
different mechanism for introns insertion in plants and animals.

710.1028 | Gemini Spectroscopy and HST Imaging of the Stellar Cluster Population in
Region B of M82 | We present new spectroscopic observations of the stellar cluster population
of region B in the prototype starburst galaxy M82 obtained with the Gillett
Gemini-North 8.1-metre telescope. By coupling the spectroscopy with UBVI
photometry acquired with the Advanced Camera for Surveys (ACS) on the Hubble
Space Telescope (HST), we derive ages, extinctions and radial velocities for
seven young massive clusters (YMCs) in region B. We find the clusters to have
ages between 70 and 200 Myr and velocities in the range 230 to 350 km/s, while
extinctions Av vary between ~1-2.5 mag. We also find evidence of differential
extinction across the faces of some clusters which hinders the photometric
determination of ages and extinctions in these cases. The cluster radial
velocities indicate that the clusters are located at different depths within
the disk, and are on regular disk orbits. Our results overall contradict the
findings of previous studies, where region B was thought to be a bound region
populated by intermediate-age clusters that formed in an independent, offset
starburst episode that commenced 600 Myr-1 Gyr ago. Our findings instead
suggest that region B is optically bright because of low extinction patches,
and this allows us to view the cluster population of the inner M82 disk, which
probably formed as a result of the last encounter with M81. This study forms
part of a series of papers aimed at studying the cluster population of M82
using deep optical spectroscopy and multi-band photometry.

710.1029 | QCD sum rules study of the meson Z^+(4430) | We use QCD sum rules to study the recently observed meson $Z^+(4430)$,
considered as a $D^*D_1$ molecule with $J^{P}=0^{-}$. We consider the
contributions of condensates up to dimension eight and work at leading order in
$\alpha_s$. We get $m_Z=(4.40\pm0.10) \GeV$ in a very good agreement with the
experimental value. We also make predictions for the analogous mesons $Z_{s}$
and $Z_{bb}$ considered as $D_s^*D_1$ and $B^*B_1$ molecules respectively. For
$Z_{s}$ we predict $m_{Z_{s}}= (4.70\pm 0.06) {\rm GeV}$, which is above the
$D_s^*D_1$ threshold, indicating that it is probably a very broad state and,
therefore, difficult to be experimentally seen. For $Z_{bb}$ we predict
$m_{Z_{bb}}= (10.74\pm 0.12) {\rm GeV}$, in agreement with quark model
predictions.

710.1031 | Thermodynamics of statistically interacting quantum gas in D dimensions | We present the exact thermodynamics (isochores, isotherms, isobars, response
functions) of a statistically interacting quantum gas in D dimensions. The
results in D=1 are those of the thermodynamic Bethe ansatz for the nonlinear
Schroedinger model, a gas with repulsive two-body contact potential. In all
dimensions the ideal boson and fermion gases are recovered in the weak-coupling
and strong-coupling limits, respectively. For all nonzero couplings ideal
fermion gas behavior emerges for D>>1 and, in the limit D->infinity, a phase

710.1032 | The very first Pop III stars and their relation to bright z~6 quasars | We discuss the link between dark matter halos hosting the first PopIII stars
formed at redshift z > 40 and the rare, massive, halos that are generally
considered to host bright z~6 quasars. We show that within the typical volume
occupied by one bright high-z QSO the remnants of the first several thousands
PopIII stars formed do not end up in the most massive halos at z~6, but rather
live in a large variety of environments. The black hole seeds planted by these
very first PopIII stars can easily grow to M > 10^{9.5} Msun by z=6 assuming
Eddington accretion with radiative efficiency epsilon~0.1. Therefore quenching
of the accretion is crucial to avoid an overabundance of supermassive black
holes. We implement a simple feedback model for the growth of the seeds planted
by PopIII stars and obtain a z~6 BH mass function consistent with the observed
QSO luminosity function.

710.1033 | Dissipation of Quantum Turbulence in the Zero Temperature Limit | Turbulence, produced by an impulsive spin-down from angular velocity Omega to
rest of a cube-shaped container, is investigated in superfluid 4He at
temperatures 0.08 K - 1.6 K. The density of quantized vortex lines L is
measured by scattering negative ions. Homogeneous turbulence develops after
time t of approximately 20 \Omega and decays as L proportional to t^(-3/2). The
corresponding energy flux epsilon = nu' (kappa L)^2, which is proportional to
t^(-3), is characteristic of quasi-classical turbulence at high Re with a
saturated energy-containing length. The effective kinematic viscosity in the

of a quantum dot | We study the evolution with magnetic field of the single-particle energy
levels high up in the energy spectrum of one dot as probed by the ground state
of the adjacent dot in a weakly coupled vertical quantum dot molecule. We find
that the observed spectrum is generally well accounted for by the calculated
spectrum for a two-dimensional elliptical parabolic confining potential, except
in several regions where two or more single-particle levels approach each
other. We focus on two two-level crossing regions which show unexpected
anti-crossing behavior and contrasting current dependences. Within a simple
coherent level mixing picture, we can model the current carried through the
coupled states of the probed dot provided the intrinsic variation with magnetic
field of the current through the states (as if they were uncoupled) is
accounted for by an appropriate interpolation scheme.

TEGA instrument on the Phoenix Lander | Since Viking has conducted its life detection experiments on Mars, many
missions have enhanced our knowledge about the environmental conditions on the
Red Planet. However, the Martian surface chemistry and the Viking lander
results remain puzzling. Non-biological explanations that favor a strong
inorganic oxidant are currently favored (e.g., Mancinelli, 1989; Quinn and
Zent, 1999; Klein, 1999, Yen et al., 2000), but problems remain regarding the
life time, source, and abundance of that oxidant to account for the Viking
observations (Zent and McKay, 1994). Alternatively, a hypothesis favoring the
biological origin of a strong oxidizer has recently been advanced (Houtkooper
and Schulze-Makuch, 2007). Here, we report about laboratory experiments that
simulate the experiments to be conducted by the Thermal and Evolved Gas
Analyzer (TEGA) instrument of the Phoenix lander, which is to descend on Mars
in May 2008. Our experiments provide a baseline for an unbiased test for
chemical versus biological responses, which can be applied at the time the
Phoenix Lander transmits its first results from the Martian surface.

710.1037 | Grassmannian spectral shooting | We present a new numerical method for computing the pure-point spectrum
associated with the linear stability of coherent structures. In the context of
the Evans function shooting and matching approach, all the relevant information
is carried by the flow projected onto the underlying Grassmann manifold. We
show how to numerically construct this projected flow in a stable and robust
manner. In particular, the method avoids representation singularities by, in
practice, choosing the best coordinate patch representation for the flow as it
evolves. The method is analytic in the spectral parameter and of complexity
bounded by the order of the spectral problem cubed. For large systems it
represents a competitive method to those recently developed that are based on
continuous orthogonalization. We demonstrate this by comparing the two methods

710.1038 | Finite-Size Scaling from the non-perturbative Renormalization Group | The phase diagram of QCD at finite temperature and density and the existence
of a critical point are currently very actively researched topics. Although
tremendous progress has been made, in the case of two light quark flavors even
the order of the phase transition at zero density is still under discussion.
Finite-size scaling is a powerful method for the analysis of phase transitions
in lattice QCD simulations. From the scaling behavior, critical exponents can
be tested and the order as well as the universality class of a phase transition
can be established. This requires knowledge of the critical exponents and the
scaling behavior. We use a non-perturbative Renormalization Group method to
obtain critical exponents and the finite-size scaling functions for the O(4)
universality class in three dimensions. These results are useful for a
comparison to the actual scaling behavior in lattice QCD simulations with two
flavors, as well as for an estimate of the size of the scaling region and the
deviations from the expected scaling behavior.

710.1039 | Stochastic excitation of non-radial modes I. High-angular-degree p modes | Turbulent motions in stellar convection zones generate acoustic energy, part
of which is then supplied to normal modes of the star. Their amplitudes result
from a balance between the efficiencies of excitation and damping processes in
the convection zones. We develop a formalism that provides the excitation rates
of non-radial global modes excited by turbulent convection. As a first
application, we estimate the impact of non-radial effects on excitation rates
and amplitudes of high-angular-degree modes which are observed on the Sun. A
model of stochastic excitation by turbulent convection has been developed to
compute the excitation rates, and it has been successfully applied to solar
radial modes (Samadi & Goupil 2001, Belkacem et al. 2006b). We generalize this
approach to the case of non-radial global modes. This enables us to estimate
the energy supplied to high-($\ell$) acoustic modes. Qualitative arguments as
well as numerical calculations are used to illustrate the results. We find that
non-radial effects for $p$ modes are non-negligible:
- for high-$n$ modes (i.e. typically $n > 3$) and for high values of $\ell$;
the power supplied to the oscillations depends on the mode inertia.
- for low-$n$ modes, independent of the value of $\ell$, the excitation is
dominated by the non-diagonal components of the Reynolds stress term. We
carried out a numerical investigation of high-$\ell$ $p$ modes and we find that
the validity of the present formalism is limited to $\ell < 500$ due to the
spatial separation of scale assumption. Thus, a model for very high-$\ell$
$p$-mode excitation rates calls for further theoretical developments, however
the formalism is valid for solar $g$ modes, which will be investigated in a
paper in preparation.

710.104 | Dust observations of Comet 9P/Tempel 1 at the time of the Deep Impact | On 4 July 2005 at 05:52 UT, the impactor of NASA's Deep Impact (DI) mission
crashed into comet 9P/Tempel 1 with a velocity of about 10 km/s. The material
ejected by the impact expanded into the normal coma, produced by ordinary
cometary activity.
The characteristics of the non-impact coma and cloud produced by the impact
were studied by observations in the visible wavelengths and in the near-IR. The
scattering characteristics of the "normal" coma of solid particles were studied
by comparing images in various spectral regions, from the UV to the near-IR.
For the non-impact coma, a proxy of the dust production has been measured in
various spectral regions. The presence of sublimating grains has been detected.
Their lifetime was found to be about 11 hours. Regarding the cloud produced by
the impact, the total geometric cross section multiplied by the albedo was
measured as a function of the color and time. The projected velocity appeared
to obey a Gaussian distribution with the average velocity of the order of 115
m/s. By comparing the observations taken about 3 hours after the impact, we
have found a strong decrease in the cross section in J filter, while that in Ks
remained almost constant. This is interpreted as the result of sublimation of
grains dominated by particles of sizes of the order of some microns.

710.1043 | X-ray properties of a sample of polar-scattered Seyfert galaxies | We present the results on an XMM-Newton systematic analysis of a sample of
nine Seyfert 1 galaxies. When observed in polarised light, the spectra of the
selected sources are similar to those of Seyfert 2 galaxies. This peculiarity
strongly suggests that these AGN are viewed with an inclination comparable with
the torus opening angle. Our results are consistent with this scenario and,
taking advantage of this favourable geometrical condition, we were able to
investigate in detail the physical properties and the distribution of the
circumnuclear gas in these sources.

710.1045 | Regularization independent of the noise level: an analysis of
quasi-optimality | The quasi-optimality criterion chooses the regularization parameter in
inverse problems without taking into account the noise level. This rule works
remarkably well in practice, although Bakushinskii has shown that there are
always counterexamples with very poor performance. We propose an average case
analysis of quasi-optimality for spectral cut-off estimators and we prove that
the quasi-optimality criterion determines estimators which are rate-optimal

710.1046 | Blow-analytic equivalence of two variable real analytic function germs | Blow-analytic equivalence is a notion for real analytic function germs,
introduced by Tzee-Char Kuo in order to develop real analytic equisingularity
theory. In this paper we give complete characterisations of blow-analytic
equivalence in the two dimensional case: in terms of the real tree model for
the arrangement of real parts of Newton-Puiseux roots and their Puiseux pairs,
and in terms of minimal resolutions. These characterisations show that in the
two dimensional case the blow-analytic equivalence is a natural analogue of
topological equivalence of complex analytic function germs. Moreover, we show
that in the two-dimensional case the blow-analytic equivalence can be made
cascade, and hence satisfies several geometric properties. It preserves, for
instance, the contact orders of real analytic arcs.
In the general $n$-dimensional case, we show that a singular real
modification satisfies the arc-lifting property.

710.105 | On the unitarity of gauged non-compact WZNW strings | In this paper we investigate the unitarity of gauged non-compact WZNW strings
i.e. string theories formulated as G/H' WZNW models, where G is a non-compact
group. These models represent string theories on non-trivial curved space-times
with one time-like component. We will prove that for the class of models
connected to Hermitian symmetric spaces, and a natural set of discrete highest
weight representations, the BRST formulation, in which the gauging is defined
through a BRST condition, yields unitarity. Unitarity requires the level times
the Dynkin index to be an integer, as well as integer valued highest weights
w.r.t. the compact subalgebra. We will also show that the BRST formulation is
not equivalent to the conventional GKO coset formulation, defined by imposing a
highest weight condition w.r.t. H'. The latter leads to non-unitary physical
string states.This is, to our knowledge, the first example of a fundamental
difference between the two formulations.

710.1051 | Charm Production at RHIC | Observations by the PHENIX and STAR collaborations suggest that a strongly
coupled quark-gluon plasma is produced in heavy-ion collisions at the
Relativistic Heavy Ion Collider (RHIC). After a brief introduction to heavy-ion
physics, measurements of heavy-quark production in heavy-ion collisions and the
modification of heavy-quark spectra by the QGP are presented. Measurements of
the total charm cross-section in several different collision systems confirm
that charm quark-antiquark pairs are produced through parton hard-scattering in
the initial stages of the collisions. Non-photonic electrons (proxies for heavy
quarks) are suppressed by about a factor of 5 in central Au + Au collisions
relative to p + p collisions. This is larger than most current theoretical

medium. The relative contributions of c and b decays to the non-photonic
electron spectrum have been predicted by perturbative QCD calculations; STAR
measurements of azimuthal correlation functions of non-photonic electrons and
hadrons agree with these predictions.

710.1052 | Channel-Adapted Quantum Error Correction for the Amplitude Damping
Channel | We consider error correction procedures designed specifically for the
amplitude damping channel. We analyze amplitude damping errors in the
stabilizer formalism. This analysis allows a generalization of the [4,1]
`approximate' amplitude damping code of quant-ph/9704002. We present this
generalization as a class of [2(M+1),M] codes and present quantum circuits for
encoding and recovery operations. We also present a [7,3] amplitude damping
code based on the classical Hamming code. All of these are stabilizer codes
whose encoding and recovery operations can be completely described with
Clifford group operations. Finally, we describe optimization options in which
recovery operations may be further adapted according to the damping probability
gamma.
