710.2353 | A Criterion For Ergodicity of Non-uniformly hyperbolic Diffeomorphisms | In this work we exhibit a new criteria for ergodicity of diffeomorphisms
involving conditions on Lyapunov exponents and general position of some
invariant manifolds. On one hand we derive uniqueness of SRB-measures for
transitive surface diffeomorphisms. On the other hand, using recent results on
the existence of blenders we give a positive answer, in the $C^1$ topology, to
a conjecture of Pugh-Shub in the context of partially hyperbolic conservative
diffeomorphisms with two dimensional center bundle.

subsector of a (0,2) supersymmetric gauged linear sigma model with target space
P1xP1, whose left-moving fermions couple to a deformation of the tangent

reduces in the limit of zero deformation to the (2,2) ring. Finally, we compare
our results with the computations carried out by Adams et al.[ABS04] and Katz

710.2356 | Patchy sticky hard spheres: analytical study and Monte Carlo simulations | We consider a fluid of hard spheres bearing one or two uniform circular
adhesive patches, distributed so as not to overlap. Two spheres interact via a
``sticky'' Baxter potential if the line joining the centers of the two spheres
intersects a patch on each sphere, and via a hard sphere potential otherwise.
We analyze the location of the fluid-fluid transition and of the percolation
line as a function of the size of the patch (the fractional coverage of the
sphere's surface) and of the number of patches within a virial expansion up to
third order and within the first two terms (C0 and C1) of a class of closures
Cn hinging on a density expansion of the direct correlation function. We find
that the locations of the two lines depend sensitively on both the total
adhesive coverage and its distribution. The treatment is almost fully
analytical within the chosen approximate theory. We test our findings by means
of specialized Monte Carlo (MC) simulations and find the main qualitative
features of the critical behaviour to be well captured in spite of the low

| cond-mat.stat-mech cond-mat.soft | we consider a fluid of hard spheres bearing one or two uniform circular adhesive patches distributed so as not to overlap two spheres interact via a sticky baxter potential if the line joining the centers of the two spheres intersects a patch on each sphere and via a hard sphere potential otherwise we analyze the location of the fluidfluid transition and of the percolation line as a function of the size of the patch the fractional coverage of the spheres surface and of the number of patches within a virial expansion up to third order and within the first two terms c0 and c1 of a class of closures cn hinging on a density expansion of the direct correlation function we find that the locations of the two lines depend sensitively on both the total adhesive coverage and its distribution the treatment is almost fully analytical within the chosen approximate theory we test our findings by means of specialized monte carlo mc simulations and find the main

homogeneous, frictionless blocks of length 1? A classical solution achieves an
overhang of $1/2 H_n$, where $H_n ~ \ln n$ is the $n$th harmonic number. This
solution is widely believed to be optimal. We show, however, that it is, in
fact, exponentially far from optimality by constructing simple $n$-block stacks
that achieve an overhang of $c n^{1/3}$, for some constant $c>0$.

710.2358 | Success and failure of programming environments - report on the design
and use of a graphic abstract syntax tree editor | The STAPLE project investigated (at the end of the eighties), a persistent
architecture for functional programming. Work has been done in two directions:
the development of a programming environment for a functional language within a
persistent system and an experiment on transferring the expertise of functional
prototyping into industry. This paper is a report on the first activity. The
first section gives a general description of Absynte - the abstract syntax tree
editor developed within the Project. Following sections make an attempt at
measuring the effectiveness of such an editor and discuss the problems raised

710.2359 | Stretching of the toroidal field and generation of magnetosonic waves in
differentially rotating plasma | We evaluate the generation of magnetosonic waves in differentially rotating
magnetized plasma. Differential rotation leads to an increase of the azimuthal
field by winding up the poloidal field lines into the toroidal field lines. An
amplification of weak seed perturbations is considered in this time-dependent
background state. It is shown that seed perturbations can be amplified by
several orders of magnitude in a differentially rotating flow. The only
necessary condition for this amplification is the presence of a non-vanishing
component of the magnetic field in the direction of the angular velocity
gradient.

710.2362 | Application of multifractal wavelet analysis to spontaneous fermentation
processes | An algorithm is presented here to get more detailed information, of mixed
culture type, based exclusively on the biomass concentration data for
fermentation processes. The analysis is performed with only the on-line
measurements of the redox potential being available. It is a two-step procedure
which includes an Artificial Neural Network (ANN) that relates the redox
potential to the biomass concentrations in the first step. Next, a multifractal
wavelet analysis is performed using the biomass estimates of the process. In
this context, our results show that the redox potential is a valuable indicator
of microorganism metabolic activity during the spontaneous fermentation. In
this paper, the detailed design of the multifractal wavelet analysis is
presented, as well as its direct experimental application at the laboratory
level

710.2363 | Global duality, signature calculus and the discrete logarithm problem | We study the discrete logarithm problem for the multiplicative group and for
elliptic curves over a finite field by using a lifting of the corresponding

show the random polynomial time equivalence for these two cases between the

710.2364 | A systematic approach to the solution of the constraints of quantum
gravity: The full theory | This is the third paper in a series outlining an algorithm to construct
finite states of quantum gravity in Ashtekar variables. In this paper we treat
the case of the Klein--Gordon field quantized with gravity on the same footing.
We address the full theory, outlining the solution to the constraints and the
construction of the corresponding wavefunction of the universe. The basic
method for the full theory is to expand the constraints relative to the
solution for the pure Kodama state and rewrite them in the form of a
generalized nonlinear group transformation of the CDJ matrix, viewed as a
nine-dimensional vector. We then outline a prescription for finding the fixed
point of the flow, and the corresponding generalized Kodama state for the full
theory is constructed. The final solution is expressed in an asymptotic series
in powers of model-specific matter inputs, suppressed by a small dimensionless
constant, relative to the pure Kodama state. We discuss this expansion from
different perspectives. Lastly, we explicitly show how the solution to the
quantized constraints establishes a wavefunction of the universe with a
predetermined semiclassical limit built in as a boundary condition on quantized
gravity in the full theory.

710.2366 | New Worlds on the Horizon: Earth-Sized Planets Close to Other Stars | The search for habitable planets like Earth around other stars fulfils an
ancient imperative to understand our origins and place in the cosmos. The past
decade has seen the discovery of hundreds of planets, but nearly all are gas
giants like Jupiter and Saturn. Recent advances in instrumentation and new
missions are extending searches to planets the size of the Earth, but closer to
their host stars. There are several possible ways such planets could form, and
future observations will soon test those theories. Many of these planets we
discover may be quite unlike Earth in their surface temperature and

710.2367 | Rubidium and lead abundances in giant stars of the globular clusters M4
and M5 | We present measurements of the neutron-capture elements Rb and Pb for bright
giants in the globular clusters M4 and M5. The clusters are of similar
metallicity ([Fe/H] = -1.2) but M4 is decidedly s-process enriched relative to
M5: [Ba/Fe] = +0.6 for M4 but 0.0 for M5. The Rb and Pb abundances were derived
by comparing synthetic spectra with high-resolution, high signal-to-noise ratio
spectra obtained with MIKE on the Magellan telescope. Abundances of Y, Zr, La,
and Eu were also obtained. In M4, the mean abundances from 12 giants are
[Rb/Fe] = 0.39 +/- 0.02 (sigma = 0.07), [Rb/Zr] = 0.17 +/- 0.03 (sigma = 0.08),
and [Pb/Fe] = 0.30 +/- 0.02 (sigma = 0.07). In M5, the mean abundances from two
giants are [Rb/Fe] = 0.00 +/- 0.05 (sigma = 0.06), [Rb/Zr] = 0.08 +/- 0.08
(sigma = 0.11), and [Pb/Fe] = -0.35 +/- 0.02 (sigma = 0.04). Within the
measurement uncertainties, the abundance ratios [Rb/Fe], [Pb/Fe] and [Rb/X] for
X = Y, Zr, La are constant from star-to-star in each cluster and none of these
ratios are correlated with O or Na abundances. While M4 has a higher Rb
abundance than M5, the ratios [Rb/X] are similar in both clusters indicating
that the nature of the s-products are very similar for each cluster but the gas
from which M4's stars formed had a higher concentration of these products.

710.2369 | Graphene-on-Sapphire and Graphene-on-Glass: Raman Spectroscopy Study | The room-temperature Raman signatures from graphene layers on sapphire and
glass substrates were compared with those from graphene on GaAs substrate and
on the standard Si/SiO2 substrate, which served as a reference. It was found
that while G peak of graphene on Si/SiO2 and GaAs is positioned at 1580 cm-1 it
is down-shifted by ~5 cm-1 for graphene-on-sapphire (GOS) and, in many cases,
splits into doublets for graphene-on-glass (GOG) with the central frequency
around 1580 cm-1. The obtained results are important for graphene
characterization and its proposed graphene applications in electronic devices.

710.237 | Using a complete spectroscopic survey to find red quasars and test the
KX method | We present an investigation of quasar colour-redshift parameter space in
order to search for radio-quiet red quasars and to test the ability of a
variant of the KX quasar selection method to detect quasars over a full range
of colour without bias. This is achieved by combining IRIS2 imaging with the
complete Fornax Cluster Spectroscopic Survey to probe parameter space
unavailable to other surveys. We construct a new sample of 69 quasars with
measured bJ - K colours. We show that the colour distribution of these quasars
is significantly different from that of the Large Bright Quasar Survey's
quasars at a 99.9% confidence level. We find 11 of our sample of 69 quasars
have signifcantly red colours (bJ - K >= 3.5) and from this, we estimate the
red quasar fraction of the K <= 18.4 quasar population to be 31%, and robustly
constrain it to be at least 22%. We show that the KX method variant used here

| astro-ph | we present an investigation of quasar colourredshift parameter space in order to search for radioquiet red quasars and to test the ability of a variant of the kx quasar selection method to detect quasars over a full range of colour without bias this is achieved by combining iris2 imaging with the complete fornax cluster spectroscopic survey to probe parameter space unavailable to other surveys we construct a new sample of 69 quasars with measured bj k colours we show that the colour distribution of these quasars is significantly different from that of the large bright quasar surveys quasars at a 999 confidence level we find 11 of our sample of 69 quasars have signifcantly red colours bj k 35 and from this we estimate the red quasar fraction of the k 184 quasar population to be 31 and robustly constrain it to be at least 22 we show that the kx method variant used here is more effective than the uvx selection method and has less colour bias than optical colourcolour selection methods | [['we', 'present', 'an', 'investigation', 'of', 'quasar', 'colourredshift', 'parameter', 'space', 'in', 'order', 'to', 'search', 'for', 'radioquiet', 'red', 'quasars', 'and', 'to', 'test', 'the', 'ability', 'of', 'a', 'variant', 'of', 'the', 'kx', 'quasar', 'selection', 'method', 'to', 'detect', 'quasars', 'over', 'a', 'full', 'range', 'of', 'colour', 'without', 'bias', 'this', 'is', 'achieved', 'by', 'combining', 'iris2', 'imaging', 'with', 'the', 'complete', 'fornax', 'cluster', 'spectroscopic', 'survey', 'to', 'probe', 'parameter', 'space', 'unavailable', 'to', 'other', 'surveys', 'we', 'construct', 'a', 'new', 'sample', 'of', '69', 'quasars', 'with', 'measured', 'bj', 'k', 'colours', 'we', 'show', 'that', 'the', 'colour', 'distribution', 'of', 'these', 'quasars', 'is', 'significantly', 'different', 'from', 'that', 'of', 'the', 'large', 'bright', 'quasar', 'surveys', 'quasars', 'at', 'a', '999', 'confidence', 'level', 'we', 'find', '11', 'of', 'our', 'sample', 'of', '69', 'quasars', 'have', 'signifcantly', 'red', 'colours', 'bj', 'k', '35', 'and', 'from', 'this', 'we', 'estimate', 'the', 'red', 'quasar', 'fraction', 'of', 'the', 'k', '184', 'quasar', 'population', 'to', 'be', '31', 'and', 'robustly', 'constrain', 'it', 'to', 'be', 'at', 'least', '22', 'we', 'show', 'that', 'the', 'kx', 'method', 'variant', 'used', 'here', 'is', 'more', 'effective', 'than', 'the', 'uvx', 'selection', 'method', 'and', 'has', 'less', 'colour', 'bias', 'than', 'optical', 'colourcolour', 'selection', 'methods']] | [-0.0037454435330306884, 0.0548450748599841, -0.08509463595893944, 0.08191778601552333, -0.1394536644476062, -0.10256095232732723, 0.11351053456700477, 0.46861325111778485, -0.11261885209719656, -0.3713075160883324, 0.034821313320702166, -0.3241711828340857, -0.02440042878707031, 0.18798387432982339, -0.050477354849198824, -0.04200969948675591, 0.022397924323614708, -0.10611472795098331, 0.004619914820320861, -0.33234589885398097, 0.2557887442334625, 0.029690066339028192, 0.20054829147283657, -0.09740020238089166, 0.10900588273985926, -0.06188479297480821, -0.11659330893119506, 0.048735295496060045, -0.15562853460516235, 0.05596461606809514, 0.28420591239166054, 0.16188702118620707, 0.2738949609489713, -0.20130581967490577, -0.1589044078368952, 0.15233341624389665, 0.19614497648627427, 0.09015939915566194, -0.01773734313930113, -0.27152445147384624, 0.14994729845565904, -0.15539514066465066, -0.14581248359324012, 0.010683253717021963, 0.02229068541867023, -0.0039002764943147326, -0.22489850350111895, 0.09894599758187508, -0.00727876675223684, 0.12552285398964938, -0.06767788213392385, -0.14439813477778538, -0.07204836845058797, 0.03583728059227282, -0.03671781964212484, 0.10275416298331343, 0.1294945557574833, -0.1389191674843775, -0.06454921038848256, 0.38099235538770093, -0.09036293304326803, -0.014513621612780357, 0.17069237501053625, -0.20581368602693856, -0.17339742482462198, 0.13756181771336715, 0.18107644712950796, 0.17548296565319157, -0.15947417441669398, -0.01660584830786667, -0.02681321400686065, 0.25744153955423765, 0.002436533204220623, 0.07857751294787478, 0.2189208734942051, 0.10439067657275201, 0.08738044277506456, 0.11174239522765385, -0.24820971108617723, 0.05708412872896546, -0.24321201497539502, -0.08474344871295589, -0.15137073415939864, 0.11023368980907808, -0.169592546226088, -0.11069497660157739, 0.37462286324364086, 0.1830087343090876, 0.2389708450131355, 0.08488198364358072, 0.2888026508594179, 0.08966985578524929, 0.12142782522425341, 0.07103204342262076, 0.3061634006780825, 0.1195596182258595, 0.0440689860425911, -0.20039831148729675, 0.013035272608774936, 0.017677672133334196] |

710.2374 | Star cluster life-times: dependence on mass, radius and environment | The dissolution time (t_dis) of clusters in a tidal field does not scale with
the ``classical'' expression for the relaxation time. First, the scaling with
N, and hence cluster mass, is shallower due to the finite escape time of stars.
Secondly, the cluster half-mass radius is of little importance. This is due to
a balance between the relative tidal field strength and internal relaxation,
which have an opposite effect on t_dis, but of similar magnitude. When external
perturbations, such as encounters with giant molecular clouds (GMC) are
important, t_dis for an individual cluster depends strongly on radius. The mean
dissolution time for a population of clusters, however, scales in the same way
with mass as for the tidal field, due to the weak dependence of radius on mass.
The environmental parameters that determine t_dis are the tidal field strength
and the density of molecular gas. We compare the empirically derived t_dis of
clusters in six galaxies to theoretical predictions and argue that encounters
with GMCs are the dominant destruction mechanism. Finally, we discuss a number
of pitfalls in the derivations of t_dis from observations, such as
incompleteness, with the cluster system of the SMC as particular example.

710.2376 | Characteristic foliation on the discriminantal hypersurface of a
holomorphic Lagrangian fibration | We give a Kodaira-type classification of general singular fibers of a
holomorphic Lagrangian fibration in Fujiki's class $\mathcal C$. Our approach
is based on the study of the characteristic vector field of the discriminantal
hypersurface, which naturally arises from the defining equation of the
hypersurface via the symplectic form. As an application, we show that the

710.2377 | Conversion Efficiencies of Heteronuclear Feshbach Molecules | We study the conversion efficiency of heteronuclear Feshbach molecules in
population imbalanced atomic gases formed by ramping the magnetic field
adiabatically. We extend the recent work [J. E. Williams et al., New J. Phys.,
8, 150 (2006)] on the theory of Feshbach molecule formations to various
combinations of quantum statistics of each atomic component. A simple
calculation for a harmonically trapped ideal gas is in good agreement with the
recent experiment [S. B. Papp and C. E. Wieman, Phys. Rev. Lett., 97, 180404
(2006)] without any fitting parameters. We also give the conversion efficiency
as an explicit function of initial peak phase space density of the majority
species for population imbalanced gases. In the low-density region where
Bose-Einstein condensation does not appear, the conversion efficiency is a
monotonic function of the initial peak phase space density, but independent of
statistics of a minority component. The quantum statistics of majority atoms
has a significant effect on the conversion efficiency. In addition,
Bose-Einstein condensation of an atomic component is the key element
determining the maximum conversion efficiency.

710.238 | Aspects of QCD Vacuum Structure | The impact of dynamical fermions on the vacuum structure of QCD is explored.
Of particular interest is the topological charge correlator, $<q(x) q(0) >$,
where negative values at small $x$ reveal a sign-alternating layered structure
to the topological-charge density of the QCD vacuum. We consider large $28^3
\times 96$ lattices from the MILC collaboration, and develop a new gluonic
definition of the topological charge density, founded on a new over-improved
stout-link smearing algorithm. The algorithm reproduces established results
from the overlap formalism and is designed to preserve instantons. We examine
the extent to which instanton-like objects are found on the lattice. Finally,
we investigate the effects of dynamical sea-quark degrees of freedom on
topology and find that the magnitudes of the negative dip in the $<q(x)q(0)>$
correlator and the positive $<q(0)^2>$ contact term are both increased with the
introduction of dynamical fermion degrees of freedom. This is in accord with
expectations based on charge renormalization and the vanishing of the
topological susceptibility in the chiral limit.

normalized coercivity HC(T)/HC(TCL) is found to show a universal behaviour,
HC(T)/HC(TCL) = h0(e^{TB/T}-e) in the temperature interval, TCL < T < TBCal,
arising from the thermal activation effect. In the above expression, h0 is a
constant, TBCal is the blocking temperature determined by the calculation, and
TCL is the temperature above which the classical Monte Carlo simulation gives a
good description on the investigated system. The present simulation has
reproduced the experimental features, including the temperature dependent
coercivity, HC(T), and the angular dependence of the remanent magnetization,
MR(phi,theta), upon the relative orientation (phi,theta) of the applied field
H. In addition, the calculation reveals that the ferromagnetic-like open
hysteresis loop is a result of a slow dynamical process at T < TBCal. The
dependence of the dynamical TBCal on the field sweeping rate R, the on-site
anisotropy constant Ku, and the number of atoms in the atomic chain, N, has
been investigated in detail.

($T_{c0}=1.45$ K) a distinct flux line lattice melting transition with
outstanding characters occurs well below the mean-field upper critical fields.
We show that a very small number of carriers with heavy mass in this system
results in exceptionally large thermal fluctuations even at subkelvin
temperatures, which are witnessed by a sizable region of the flux line liquid
phase. The uniqueness is further highlighted by an enhancement of the
quasiparticle mean free path below the melting transition, implying a possible
formation of a quasiparticle Bloch state in the periodic flux line lattice.

710.2383 | Direct Amplification of Sound By Light | A new device, the opto-acoustic parametric amplifier (OAPA), is introduced,
which is analogous to an optical parametric amplifier (OPA). The radiation
pressure reaction of light on the reflective surface of an acoustic resonator
provides nonlinearity similar to the Kerr effect in the OPA. The OAPA can be
tuned to operate in two regimes. In the positive gain regime, an acoustic

710.2385 | Effect of initial condition of inflation on power and angular power
spectra in finite slow-roll inflation | The effect of the initial condition of inflation on the power spectra of
scalar and tensor perturbations is estimated assuming a slow-roll inflation
model. By defining a more general initial state in inflation particular
properties of the power spectrum such as oscillation can be revealed. The
behavior of the power spectrum is shown to exhibit a step-like variation with
respect to finite inflation length in cases of both radiation- and scalar
matter-dominated pre-inflation. The power spectrum is shown to oscillate in the
radiation-dominated case. The effects of such a power spectrum on the TT and TE
power spectra are examined for three typical slow-roll inflation models; a
small-field model, a large field model, and a hybrid model, considering both
pre-inflation models. It is found that the discrepancies between WMAP3 data and
the Lambda CDM model, such as suppression of the spectrum at l=2, may be
explained to a certain extent by the finite length of inflation for inflation
of close to 60 e-folds. The small-field inflation model with scalar
matter-dominated pre-inflation provides the best fit to the WMAP3 data among
the models considered. Relatively large changes in the angular TT power
spectrum occur in response to small changes in inflation length in the
radiation-dominated pre-inflation models, and half cases do not fit well with
the observed data. This behavior is considered to be attributable to the
oscillatory behavior of the power spectrum. The scalar matter-dominated case is
thus preferred to the radiation-dominated case of pre-inflation, independent of
the length of inflation.

710.2387 | Characterizing arbitrarily slow convergence in the method of alternating
projections | In 1997, Bauschke, Borwein, and Lewis have stated a trichotomy theorem that
characterizes when the convergence of the method of alternating projections can
be arbitrarily slow. However, there are two errors in their proof of this
theorem. In this note, we show that although one of the errors is critical, the
theorem itself is correct. We give a different proof that uses the
multiplicative form of the spectral theorem, and the theorem holds in any real
or complex Hilbert space, not just in a real Hilbert space.

710.2388 | On Chern-Moser normal forms of strongly pseudoconvex hypersurfaces with
high-dimensional stability group | We explicitly describe germs of strongly pseudoconvex non-spherical
real-analytic hypersurfaces $M$ at the origin in $\CC^{n+1}$ for which the
group of local CR-automorphisms preserving the origin has dimension $d_0(M)$
equal to either $n^2-2n+1$ with $n\ge 2$, or $n^2-2n$ with $n\ge 3$. The
description is given in terms of equations defining hypersurfaces near the
origin, written in the Chern-Moser normal form. These results are motivated by
the classification of locally homogeneous Levi non-degenerate hypersurfaces in

Bi$_2$FeTiO$_6$ is a potential multiferroic in which the magnetism and
ferroelectricity coexist . A ferromagnetic configuration with magnetic moment
of 4 $\mu_B$ per formula unit have been reported with respect to the minimum
total energy. Spontaneous polarization of 27.3 $\mu$ C/cm$^2$, caused mainly by
the ferroelectric distortions of Ti, was evaluated using the berry phase
approach in the modern theory of polarization. The Bi-6s stereochemical
activity of long-pair and the `d$^0$-ness' criterion in off-centring of Ti were
coexisting in the predicted new system. In view of the oxidation state of
Bi$^{3+}$,Fe$^{2+}$,Ti$^{4+}$, and O$^{2-}$ from the orbital-resolved density
of states of the Bi-6p, Fe-3d,Ti-3d, and O-2p states,the valence state of

710.2392 | Characterization of the Microstructure of Zirconolite-Based
Glass-Ceramics | December 1991 legislation in France has spurred research on enhanced
separation and conditioning or transmutation of long-lived radionuclides from
high level radioactive wastes (HLW). In this field, we have studied
zirconolite-based glass-ceramics in which the crystalline phase (zirconolite:
CaZrTi2O7) aimed to preferentially incorporate minor actinides is embedded in a
glassy calcium aluminosilicate matrix. At the laboratory scale, the
crystallization of the parent glass is carried out thanks to a two-step thermal
treatment: a nucleation stage followed by a growth stage. This paper presents
the evolution of the crystallization, followed by scanning electron microscopy
(SEM) and X-ray diffraction (XRD), with the temperature of the crystal growth
thermal treatment, in the range 950 degrees - 1350 degrees C.

710.2394 | Recent Progress in Effective Field Theory in the One-Nucleon Sector | Chiral perturbation theory (ChPT) is the effective field theory of the strong
interactions at low energies. We will address the issue of a consistent power
counting scheme in a manifestly Lorentz-invariant formulation of baryon ChPT.
As applications we show how the inclusion of vector and axial-vector mesons in

710.2395 | Stability of Palatini-f(R) cosmology | The evolution of linear cosmological perturbations in modified theories of
gravity is investigated assuming the Palatini formalism. It has been discussed
about the stability problem in this model based on the equivalence between f(R)
gravity and the scalar tensor theory. However, we study this problem in the
physical frame where the matter is minimally coupled. In general, the stability
of the superhorizon metric evolution depends on models. We show that the
deviation from the superhorizon metric evolution is null for a specific choice
for the nonlinear Einstein-Hilbert action, $f(\hat{R}) \sim \hat{R}^{n}$, where
$n \neq 0,2,3$. Thus the stability of metric fluctuation is guaranteed in these
models. We also study the matter density fluctuation in the general gauge and
show the differential equations in super and sub-horizon scales.

710.2397 | Initial-Final Mass Relationship for Stars of Different Metallicities | Following Paczy\'{n}ski & Zi\'{o}lkowski (1968) and Han et al. (1994), we
assume that the envelope of an asymptotic giant branch (AGB) or a first giant
branch (FGB) star is lost when the binding energy of the envelope is equal to
zero ($\Delta W=0$) and the core mass of the AGB star or the FGB star at the
point ($\Delta W=0$) is taken as the final mass. Using this assumption, we
calculate the IFMRs for stars of different metallicities.We find that the IFMRs
depends strongly on the metallicity, i.e. $Z=0.0001, 0.0003, 0.001, 0.004,
0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.08$ and 0.1. From $Z=0.04$, the final
mass of the stars with a given initial mass increases with increasing or
decreasing metallicity. The difference of the final mass due to the metallicity
may be up to 0.4 $M_{\odot}$. A linear fit of the initial-final mass
relationship in NGC 2099 (M37) shows a potential evidence of the effect of
metallicity on the IFMR. The IFMR for stars of $Z=0.02$ obtained in the paper
matches well with those inferred observationally in the Galaxy. For $Z\geq
0.02$, helium WDs are obtained from the stars of $M_{\rm i}\leq 1.0 M_{\odot}$
and this result is upheld by the discovery of numerous low-mass WDs in NGC 6791
which is a metal-rich old open cluster. Using the IFMR for stars of $Z=0.02$
obtained in the paper, we have reproduced the mass distribution of DA WDs in
Sloan DR4 except for some ultra-massive white dwarfs. The trend that the mean
mass of WDs decreases with effective temperature may originate from the
increase of the initial metallicities of stars. We predict that metal-rich
low-mass stars may become under-massive white dwarfs.

rotating more rapidly than about $v \sin{i} = 10$ km s$^{-1}$ with the Fourier

samples to look for correlations between differential rotation and other
stellar parameters. I analyze the fraction of differentially rotating stars as
a function of color, rotation, and activity in a large sample of F-type stars.
Color and rotation exhibit a correlation with differential rotation in the
sense that more stars are rotating differentially in the cooler, less rapidly
rotating stars. Effects of rotation and color, however, cannot be disentangled
in the underlying sample. No trend with activity is found.

710.2399 | Signatures of inflow motion in cores of massive star formation:
Potential collapse candidates | Using the IRAM 30 m telescope, a mapping survey in optically thick and thin
lines was performed towards 46 high mass star-forming regions. The sample
includes UC H{\sc ii} precursors and UC H{\sc ii} regions. Seventeen sources
are found to show "blue profiles", the expected signature of collapsing cores.
The excess of sources with blue over red profiles ([$N_{\rm blue}$ -- $N_{\rm
red}$]/$N_{\rm total}$) is 29% in the HCO$^+$ $J$=1--0 line, with a probability
of 0.6% that this is caused by random fluctuations. UC H{\sc ii} regions show a
higher excess (58%) than UC H{\sc ii} precursors (17%), indicating that
material is still accreted after the onset of the UC H{\sc ii} phase. Similar
differences in the excess of blue profiles as a function of evolutionary state
are not observed in low mass star-forming regions. Thus, if confirmed for high
mass star-forming sites, this would point at a fundamental difference between
low- and high-mass star formation. Possible explanations are inadequate
thermalization, stronger influence of outflows in massive early cores, larger

710.24 | On invisible plasma content in radio-loud AGNs: The case of TeV blazar
Markarian 421 | Invisible plasma content in blazar jets such as protons and/or thermal
electron-positron ($e^{\pm}$) pairs is explored through combined arguments of
dynamical and radiative processes. By comparing physical quantities required by
the internal shock model with those obtained through the observed broadband
spectra for Mrk 421, we obtain that the ratio of the Lorentz factors of a pair
of cold shells resides in about $2\sim 20$, which implies that the shocks are
at most mildly relativistic. Using the obtained Lorentz factors, the total mass
density $\rho$ in the shocked shells is investigated. The upper limit of $\rho$
is obtained from the condition that thermal bremsstrahlung emission should not
exceed the observed $\gamma$-ray luminosity, whilst the lower limit is
constrained from the condition that the energy density of non-thermal electrons
is smaller than that of the total plasma. Then we find $\rho$ is $10^2$-$10^3$
times heavier than that of non-thermal electrons for pure $e^{\pm}$ pairs,
while $10^2$-$10^6$ times heavier for pure electron-proton ($e/p$) content,
implying the existence of a large amount of invisible plasma. The origin of the
continuous blazar sequence is shortly discussed and we speculate that the total
mass density and/or the blending ratio of $e^{\pm}$ pairs and $e/p$ plasma
could be new key quantities for the origin of the sequence.

710.2401 | Tracing non-equilibrium plasma dynamics on the attosecond timescale in
small clusters | It is shown that the energy absorption of a rare-gas cluster from a
vacuum-ultraviolet (VUV) pulse can be traced with time-delayed
extreme-ultraviolet (XUV) attosecond probe pulses by measuring the kinetic
energy of the electrons detached by the probe pulse. By means of this scheme we
demonstrate, that for pump pulses as short as one femtosecond, the charging of
the cluster proceeds during the formation of an electronic nano-plasma inside
the cluster. Using moderate harmonics for the VUV and high harmonics for the
XUV pulse from the same near-infrared laser source, this scheme with well
defined time delays between pump and probe pulses should be experimentally
realizable. Going to even shorter pulse durations we predict that pump and

Chinese A-share stocks | We use high-frequency data of 1364 Chinese A-share stocks traded on the
Shanghai Stock Exchange and Shenzhen Stock Exchange to investigate the intraday
patterns in the bid-ask spreads. The daily periodicity in the spread time
series is confirmed by Lomb analysis and the intraday bid-ask spreads are found
to exhibit $L$-shaped pattern with idiosyncratic fine structure. The intraday
spread of individual stocks relaxes as a power law within the first hour of the
continuous double auction from 9:30AM to 10:30AM with exponents
$\beta_{\rm{SHSE}}=0.19\pm0.069$ for the Shanghai market and
$\beta_{\rm{SZSE}}=0.18\pm0.067$ for the Shenzhen market. The power-law
relaxation exponent $\beta$ of individual stocks is roughly normally
distributed. There is evidence showing that the accumulation of information
widening the spread is an endogenous process.

710.2403 | Double quantum dot as a probe of nonequilibrium charge fluctuations at
the quantum point contact | Absorption of energy quanta generated by quantum point contact results in the
inelastic current through the double quantum dot placed nearby. In contrast to
a single quantum dot, the inelastic current through the double quantum dot is
sensitive to the energy dependence of the quantum point contact transmission,

710.2406 | Quasi-exactly solvable quasinormal modes | We consider quasinormal modes with complex energies from the point of view of
the theory of quasi-exactly solvable (QES) models. We demonstrate that it is
possible to find new potentials which admit exactly solvable or QES quasinormal
modes by suitable complexification of parameters defining the QES potentials.

710.2409 | Precise predictions for MSSM Higgs-boson production in bottom-quark
fusion | The main production mechanism for supersymmetric Higgs particles at hadron
colliders crucially depends on the size of their Yukawa couplings to bottom
quarks. For sufficiently large tan(beta) the total cross section for some of
the neutral Higgs bosons in the MSSM is dominated by bottom-quark fusion. After
an introduction to bottom-associated Higgs production, we discuss the complete
O(alpha) electroweak and O(alpha_s) strong corrections for the bb-fusion
channel in the MSSM. Choosing proper renormalization and input-parameter
schemes, an improved Born approximation, constructed from previously known
results, can absorb the bulk of the corrections so that the remaining

projecting the link variables on the circle S^1 -> R for compact U(1) or the
3-sphere S^3 -> R^3 for SU(2) before imposing the Landau gauge condition. This
can reduce the number of Gribov copies exponentially and solves the Gribov
problem in compact U(1) where it is a lattice artifact. Applied to the maximal
Abelian subgroup this might be just enough to avoid the perfect cancellation
amongst the Gribov copies in a lattice BRST formulation for SU(N), and thus to
avoid the Neuberger 0/0 problem. The continuum limit of the Landau gauge
remains unchanged.

710.2412 | Nonet symmetry in \eta, \eta^{\prime} and B\to K\eta,K\eta^{\prime}
decays | The nonet symmetry scheme seems to describe rather well the masses and
$\eta-\eta^{\prime}$ mixing angle of the ground state pseudo-scalar mesons. It
is expected that nonet symmetry should also be valid for the matrix elements of
the pseudo-scalar densitty operators which play an important role in charmless
two-body B decays with $\eta$ or $\eta^{\prime}$ in the final state. Starting
from the divergences of the SU(3) octet and singlet axial vector currents, we
show that nonet symmetry for the pseudo-scalar mass term implies nonet symmetry
for the pseudo-scalar density operators. In this nonet symmetry scheme, we find
that the branching ratio $B\to PP,PV$, with $\eta$ in the final state agrees
well with data, while those with $\eta'$ are underestimated, but by increasing
the $B\to \eta'$ form factor by $40-50%$, one could explain the tree-dominated
$B^{-}\to \pi^{-}\eta'$ and $B^{-}\to \rho^{-}\eta'$ measured branching ratios.
With this increased form factor and with only a moderate annihilation
contribution, we are able to obtain $62\times 10^{-6}$ for the
penguin-dominated $B^{-}\to K^{-}\eta'$ branching ratios, quite close to the
measured value. This supports the predicted value for the $B\to \eta'$ form
factor in PQCD and light-cone sum rules approach. A possible increase by 15% of
$<0|\bar{s} i\gamma_5 s|s\bar{s}>$ for $\eta_{0} $ would bring the predicted
$B^{-}\to K^{-}\eta'$ branching ratio to $69.375\times 10^{-6}$, very close to
experiment.
| hep-ph hep-ex | the nonet symmetry scheme seems to describe rather well the masses and etaetaprime mixing angle of the ground state pseudoscalar mesons it is expected that nonet symmetry should also be valid for the matrix elements of the pseudoscalar densitty operators which play an important role in charmless twobody b decays with eta or etaprime in the final state starting from the divergences of the su3 octet and singlet axial vector currents we show that nonet symmetry for the pseudoscalar mass term implies nonet symmetry for the pseudoscalar density operators in this nonet symmetry scheme we find that the branching ratio bto pppv with eta in the final state agrees well with data while those with eta are underestimated but by increasing the bto eta form factor by 4050 one could explain the treedominated bto pieta and bto rhoeta measured branching ratios with this increased form factor and with only a moderate annihilation contribution we are able to obtain 62times 106 for the penguindominated bto keta branching ratios quite close to the measured value this supports the predicted value for the bto eta form factor in pqcd and lightcone sum rules approach a possible increase by 15 of 0bars igamma_5 ssbars for eta_0 would bring the predicted bto keta branching ratio to 69375times 106 very close to experiment | [['the', 'nonet', 'symmetry', 'scheme', 'seems', 'to',

710.2413 | Inverted Hybrid Inflation as a solution to gravitino problems in Gravity
Mediation | It was recently found that the decay of inflaton and the SUSY breaking field
produces many gravitinos in the gravity mediation scenario. These discoveries
led to an exclusion of many inflation models such as chaotic, (smooth) hybrid,
topological and new inflation models. Under these circumstances we searched for
a successful inflation model and found that the ``inverted'' hybrid inflation
models can solve the gravitino overproduction problem by their distinctive
shape of the potential. Furthermore, we found that this inflation model
simultaneously can explain the observed baryon asymmetry through the
non-thermal leptogenesis and is consistent with the WMAP results, that is,
$n_s=0.951^{+0.015}_{-0.019}$ and the negligible tensor to scalar ratio.

710.2415 | Single Production of Doubly Charged Higgsinos at linear e-e- colliders | Several extended supersymmetric models, motivated by either grand
unification, or by neutrino mass generation, predict light doubly charged
higgsinos. We study the production of a single doubly charged higgsino and its
decay channels at the International Linear Collider (ILC) operating in the e-e-
mode. We analyze the production cross section for e-e- -->
tilde{Delta}^{--}_{L,R} chi^0_1 as a function of different kinematic variables,
followed by the decay, through several channels, of the doubly charged higgsino
into a final state of two leptons plus missing energy. We include the standard
model background and discuss how kinematic cuts could be used effectively to
limit this background. Single production of these exotics could provide a
spectacular signal for a new underlying symmetry and for physics beyond the
minimal supersymmetric standard model.

710.2419 | The Variable Hierarchy for the Games mu-Calculus | Parity games are combinatorial representations of closed Boolean mu-terms. By
adding to them draw positions, they have been organized by Arnold and one of
the authors into a mu-calculus. As done by Berwanger et al. for the
propositional modal mu-calculus, it is possible to classify parity games into
levels of a hierarchy according to the number of fixed-point variables. We ask
whether this hierarchy collapses w.r.t. the standard interpretation of the
games mu-calculus into the class of all complete lattices. We answer this
question negatively by providing, for each n >= 1, a parity game Gn with these
properties: it unravels to a mu-term built up with n fixed-point variables, it
is semantically equivalent to no game with strictly less than n-2 fixed-point
variables.

710.242 | Magnetoplasmons excitations in graphene for filling factors $\nu \leq 6$ | In the frame of the Hartree-Fock approximation, the dispersion of
magnetoplasmons in Graphene is derived for all types of transitions for filling
factors $\nu\leq 6$. The optical conductivity components of the magnetoplasmon
curves are calculated. It is shown that the electron-electron interactions lead

710.2421 | Spontaneous emission spectrum of a two-level atom in a very high Q
cavity | In this paper we consider an initially excited two-level system coupled to a
monomode cavity, and compute exact expressions for the spectra spontaneously
emitted by each system in the general case where they have arbitrary linewidths
and frequencies. Our method is based on the fact that this problem has an
easily solvable classical counterpart, which provides a clear interpretation of
the evidenced phenomena. We show that if the cavity linewidth is much lower
than the atomic linewidth, photons are emitted at the cavity frequency, even if
the atom and the cavity are strongly detuned. We also study the links between
the spontaneous emission spectra and the fluorescence spectra emitted when the
atom is driven by a classical field of tunable frequency.

the Robin inequality $\sigma(n)<e^\gamma n\log\log n$ holds for every integer

the Euler-Mascheroni constant. We exhibit a broad class of subsets $\cS$ of the
natural numbers such that the Robin inequality holds for all but finitely many

our assertions with the Nicolas inequality $n/\phi(n)<e^{\gamma}\log \log n$;
since $\sigma(n)/n<n/\phi(n)$ for $n>1$ our results for the Robin inequality

710.2426 | Low angular momentum accretion flow model of Sgr A* activity | Sgr A* is a source of strongly variable emission in several energy bands. It
is generally agreed that this emission comes from the material surrounding the
black hole which is either falling in or flowing out. The activity must be
driven by accretion but the character of accretion flow in this object is an
open question. We suggest that the inflow is dominated by the relatively low
angular momentum material originating in one of the nearby group of stars. Such
material flows in directly towards the black hole up to the distance of order
of ten Schwarzschild radii or less, where it hits the angular momentum barrier
which leads naturally to a flow variability. We study both the analytical and
the numerical solutions for the flow dynamics, and we analyze the radiation
spectra in both cases using the Monte Carlo code to simulate the synchrotron,
bremsstrahlung and the Compton scattering. Our model roughly reproduces the
broad band spectrum of Sgr A* and its variability if we allow for a small
fraction of energy to be converted to non-thermal population of electrons. It
is also consistent (for a range of viewing angles) with the strong constraints
on the amount of circumnuclear material imposed by the measurements of the
Faraday rotation.

hits the angular momentum barrier which leads naturally to a flow variability we study both the analytical and the numerical solutions for the flow dynamics and we analyze the radiation spectra in both cases using the monte carlo code to simulate the synchrotron bremsstrahlung and the compton scattering our model roughly reproduces the broad band spectrum of sgr a and its variability if we allow for a small fraction of energy to be converted to nonthermal population of electrons it is also consistent for a range of viewing angles with the strong constraints on the amount of circumnuclear material imposed by the measurements of the faraday rotation | [['sgr', 'a', 'is', 'a', 'source', 'of', 'strongly', 'variable', 'emission', 'in', 'several', 'energy', 'bands', 'it',

collaboration supports the observation of an excess in the cosmic-ray positron
spectrum by previous balloon experiments. The combination of the various
experimental data establishes a deviation from the expected background with a
significance of more than four standard deviations. The observed change in the
spectral index cannot be explained without introducing a new source of
positrons. When interpreted within the MSSM a consistent description of the
antiproton spectrum, the diffuse gamma-ray flux and the positron fraction is
obtained which is compatible with all other experimental data, including recent

710.2431 | Control of recollision wave packets for molecular orbital tomography
using short laser pulses | The tomographic imaging of arbitrary molecular orbitals via high-order
harmonic generation requires that electrons recollide from one direction only.
Within a semi-classical model, we show that extremely short phase-stabilized
laser pulses offer control over the momentum distribution of the returning
electrons. By adjusting the carrier-envelope phase, recollisions can be forced
to occur from mainly one side, while retaining a broad energy spectrum. The
signatures of the semi-classical distributions are observed in harmonic spectra
obtained by numerical solution of the time-dependent Schr\"{o}dinger equation.

710.2432 | Isospectral orbifolds with different maximal isotropy orders | We construct pairs of compact Riemannian orbifolds which are isospectral for
the Laplace operator on functions such that the maximal isotropy order of
singular points in one of the orbifolds is higher than in the other. In one
type of examples, isospectrality arises from a version of the famous Sunada
theorem which also implies isospectrality on $p$-forms; here the orbifolds are
quotients of certain compact normal homogeneous spaces. In another type of
examples, the orbifolds are quotients of Euclidean $\R^3$ and are shown to be
isospectral on functions using dimension formulas for the eigenspaces. In the
latter type of examples the orbifolds are not isospectral on 1-forms. Along the
way we also give several additional examples of isospectral orbifolds which do

710.2434 | Integrability of geodesic flows and isospectrality of Riemannian
manifolds | We construct a pair of compact, eight-dimensional, two-step Riemannian
nilmanifolds $M$ and $M'$ which are isospectral for the Laplace operator on
functions and such that $M$ has completely integrable geodesic flow in the
sense of Liouville, while $M'$ has not. Moreover, for both manifolds we analyze
the structure of the submanifolds of the unit tangent bundle given by to
maximal continuous families of closed geodesics with generic velocity fields.
The structure of these submanifolds turns out to reflect the above
(non)integrability properties. On the other hand, their dimension is larger
than that of the Lagrangian tori in $M$, indicating a degeneracy which might
explain the fact that the wave invariants do not distinguish an integrable from
a nonintegrable system here. Finally, we show that for $M$, the invariant
eight-dimensional tori which are foliated by closed geodesics are dense in the

710.2436 | Optical afterglows of gamma-ray bursts: a bimodal distribution?" | The luminosities of the optical afterglows of Gamma Ray Bursts, 12 hours
(rest frame time) after the trigger, show a surprising clustering, with a
minority of events being at a significant smaller luminosity. If real, this
dichotomy would be a crucial clue to understand the nature of optically dark
afterglows, i.e. bursts that are detected in the X-ray band, but not in the
optical. We investigate this issue by studying bursts of the pre-Swift era,
both detected and undetected in the optical. The limiting magnitudes of the
undetected ones are used to construct the probability that a generic bursts is
observed down to a given magnitude limit. Then, by simulating a large number of
bursts with pre-assigned characteristics, we can compare the properties of the
observed optical luminosity distribution with the simulated one. Our results
suggest that the hints of bimodality present in the observed distribution
reflects a real bimodality: either the optical luminosity distributions of
bursts is intrinsically bimodal, or there exists a population of bursts with a
quite significant grey absorption, i.e. wavelength independent extinction. This
population of intrinsically weak or grey-absorbed events can be associated to
dark bursts.

710.2437 | Discovery of 18 Jupiter mass RV companion orbiting the brown dwarf
candidate ChaHa8 | We report the discovery of a 16-20 Jupiter mass radial velocity companion
around the very young (3 Myr) brown dwarf candidate ChaHa8. Based on
high-resolution echelle spectra of ChaHa8 taken between 2000 and 2007 with UVES
at the VLT, a companion was detected through RV variability with a
semi-amplitude of 1.6 km/s. A Kepler fit to the data yields an orbital period
of the companion of 1590 days and an eccentricity of e=0.49. A companion
minimum mass M2sin i between 16 and 20 Jupiter masses is derived when using
model-dependent mass estimates for the primary. The mass ratio M2/M1 might be
as small as 0.2 and, with a probability of 87%, it is less than 0.4. ChaHa8
harbors most certainly the lowest mass companion detected so far in a close (~1
AU) orbit around a brown dwarf or very low-mass star. From the uncertainty in
the orbit solution, it cannot completely be ruled out that the companion has a
mass in the planetary regime. Its discovery is in any case an important step
towards RV planet detections around BDs. Further, ChaHa8 is the fourth known
spectroscopic brown dwarf or very low-mass binary system with an RV orbit
solution and the second known very young one.

710.2442 | QCD on the Cell Broadband Engine | We evaluate IBM's Enhanced Cell Broadband Engine (BE) as a possible building
block of a new generation of lattice QCD machines. The Enhanced Cell BE will
provide full support of double-precision floating-point arithmetics, including
IEEE-compliant rounding. We have developed a performance model and applied it
to relevant lattice QCD kernels. The performance estimates are supported by
micro- and application-benchmarks that have been obtained on currently
available Cell BE-based computers, such as IBM QS20 blades and PlayStation 3.
The results are encouraging and show that this processor is an interesting

710.2443 | Observe matter falling into a black hole | It has been well known that in the point of view of a distant observer, all
in-falling matter to a black hole (BH) will be eventually stalled and "frozen"
just outside the event horizon of the BH, although an in-falling observer will
see the matter falling straight through the event horizon. Thus in this "frozen
star" scenario, as distant observers, we could never observe matter falling
into a BH, neither could we see any "real" BH other than primordial ones, since
all other BHs are believed to be formed by matter falling towards singularity.
Here we first obtain the exact solution for a pressureless mass shell around a
pre-existing BH. The metrics inside and interior to the shell are all different
from the Schwarzschild metric of the enclosed mass. The metric interior to the
shell can be transformed to the Schwarzschild metric for a slower clock which
is dependent of the location and mass of the shell. Another result is that
there does not exist a singularity nor event horizon in the shell. Therefore
the "frozen star" scenario is incorrect. We also show that for all practical
astrophysical settings the in-falling time recorded by an external observer is
sufficiently short that future astrophysical instruments may be able to follow
the whole process of matter falling into BHs. The distant observer could not
distinguish between a "real" BH and a "frozen star", until two such objects
merge together. It has been proposed that electromagnetic waves will be
produced when two "frozen stars" merge together, but not true when two "real"
bare BHs merge together. However gravitational waves will be produced in both
cases. Thus our solution is testable by future high sensitivity astronomical
observations.

710.2444 | Determining QCD Low-Energy Couplings from lattice simulations | Different strategies for the computation of QCD low-energy couplings by
matching lattice QCD with the chiral effective theory are reviewed. After
recalling the main features of the chiral effective theory in the epsilon- and
p- regimes, the current status of the determination of leading order (Sigma, F)
and next-to-leading order (l_i, L_i) low-energy constants is summarised,

710.2446 | The structure of verbal sequences analyzed with unsupervised learning
techniques | Data mining allows the exploration of sequences of phenomena, whereas one
usually tends to focus on isolated phenomena or on the relation between two
phenomena. It offers invaluable tools for theoretical analyses and exploration
of the structure of sentences, texts, dialogues, and speech. We report here the
results of an attempt at using it for inspecting sequences of verbs from French
accounts of road accidents. This analysis comes from an original approach of
unsupervised training allowing the discovery of the structure of sequential
data. The entries of the analyzer were only made of the verbs appearing in the
sentences. It provided a classification of the links between two successive
verbs into four distinct clusters, allowing thus text segmentation. We give
here an interpretation of these clusters by applying a statistical analysis to
independent semantic annotations.

710.2447 | Enhanced visibility of graphene: effect of one-dimensional photonic
crystal | We investigate theoretically the light reflectance of a graphene layer
prepared on the top of one-dimensional Si/SiO2 photonic crystal (1DPC). It is
shown that the visibility of the graphene layers is enhanced greatly when 1DPC
is added, and the visibility can be tuned by changing the incident angle and

is of the general-purpose type in the sense that it in principle deals with any
quadratically integrable integrand on a unit hyper-cube of arbitrary dimension.
In contrast to most existing systems of this type, it does not ask for the
integrand as an input variable, but provides a number of routines which can be
plugged into a given Monte Carlo program in order to improve its efficiency "on
the fly" while running. Due to the nature of its design, it can also be used
for density estimation, i.e., for the analysis of data points coming from an
external source.

710.2452 | EG And: FUSE and HST/STIS Monitoring of an Eclipsing Symbiotic Binary | We present highlights and an overview of 20 FUSE and HST/STIS observations of
the bright symbiotic binary EG And. The main motivation behind this work is to
obtain spatially-resolved information on an evolved giant star in order to
understand the mass-loss processes at work in these objects. The system
consists of a low-luminosity white dwarf and a mass-losing, non-dusty M2 giant.
The ultraviolet observations follow the white dwarf continuum through periodic
gradual occultations by the wind and chromosphere of the giant, providing a
unique diagnosis of the circumstellar gas in absorption. Unocculted spectra
display high ionization features, such as the OVI resonance doublet which is
present as a variable (hourly time-scales), broad wind profile, which diagnose
the hot gas close to the dwarf component. Spectra observed at stages of partial
occultation display a host of low-ionization, narrow, absorption lines, with
transitions observed from lower energy levels up to ~5eV above ground. This
absorption is due to chromospheric/wind material, with most lines due to
transitions of SiII, PII, NI, FeII and NiII, as well as heavily damped HI Lyman
series features. No molecular features are observed in the wind acceleration
region despite the sensitivity of FUSE to molecular hydrogen. From analysis of
the ultraviolet dataset, as well as optical data, we find that the dwarf
radiation does not dominate the wind acceleration region of the giant, and that
observed thermal and dynamic wind properties are most likely representative of
isolated red giants.
