710.2153 | Phase Separation and Charge Transfer in a K-doped C60 Monolayer on
Ag(001) | We have performed a scanning tunneling microscopy and spectroscopy study of
potassium-doped C60 monolayers (KxC60) on Ag(001) in the regime of x ~ 1. Low
temperature annealing (640 K) leads to the formation of two well-ordered KxC60
phases that exhibit differing levels of electron charge transfer. Further
annealing (710 K) distills out the higher electron-doped phase from the lower
electron-doped phase, leaving behind a third C60 phase completely devoid of K.
Spectroscopic measurements indicate that the electron-doping level of the
higher electron-doped KC60 phase is anomalously large.

710.2155 | Interpreting Recoil For Undergraduate Students | In this paper, I outline some problems in the students' understanding of the
explanation of recoil motion when introduced to them in the context of Newton's
third law. I propose to explain the origin of recoil from a microscopic point
of view, which emphasizes the exact mechanism leading to recoil. This mechanism
differs from one system to another. Several examples that can be easily
implemented in the classroom environment are given in this paper. Such a
profound understanding of the origin of recoil help students avoid some of the
misconceptions that might arise from the phenomenological approach, and
stimulates their thinking in the fundamental origins of other physical
phenomena.

710.2156 | Collaborative OLAP with Tag Clouds: Web 2.0 OLAP Formalism and
Experimental Evaluation | Increasingly, business projects are ephemeral. New Business Intelligence
tools must support ad-lib data sources and quick perusal. Meanwhile, tag clouds
are a popular community-driven visualization technique. Hence, we investigate
tag-cloud views with support for OLAP operations such as roll-ups, slices,
dices, clustering, and drill-downs. As a case study, we implemented an
application where users can upload data and immediately navigate through its ad
hoc dimensions. To support social networking, views can be easily shared and
embedded in other Web sites. Algorithmically, our tag-cloud views are
approximate range top-k queries over spontaneous data cubes. We present
experimental evidence that iceberg cuboids provide adequate online

710.2157 | Ongoing Assembly of Massive Galaxies by Major Merging in Large Groups
and Clusters from the SDSS | We investigate the incidence of major mergers creating >10e11 Msun galaxies
in present-day groups and clusters more massive than 2.5e13 Msun. We identify
38 pairs of massive galaxies with mutual tidal interaction signatures selected
from >5000 galaxies with >5e10 Msun that reside in 845 such groups. We fit the
images of each galaxy pair as the line-of-sight projection of symmetric models
and identify mergers by the presence of residual asymmetries around each
progenitor, such as off-center isophotes, broad tidal tails, and dynamical
friction wakes. At the resolution and sensitivity of the SDSS, such mergers are
found in 16% of high-mass, galaxy-galaxy pairs with magnitude differences of
<1.5 and <30 kpc projected separations. We find that 90% of these mergers have
nearly equal-mass progenitors with red-sequence colors and
centrally-concentrated morphologies, the hallmarks of dissipationless merger
simulations. Mergers at group centers are more common than between 2
satellites, but both are morphologically indistinguishable and we tentatively
conclude that the latter are likely located at the dynamical centers of
recently accreted subhalos. The frequency of central and satellite merging
diminishes with group mass consistent with dynamical friction expectations.
Based on reasonable assumptions, the centers of these massive halos are growing
in stellar mass by 1-9% per Gyr, on average. Compared to all LRG-LRG mergers,
we find a 2-9 times higher rate for their merging when restricted to these
dense environments. Our results imply that the massive end of the galaxy
population continues to evolve hierarchically at a measurable level, and that
the centers of massive groups are the preferred environment for merger-driven
galaxy assembly. (abridged)

710.2158 | The double-Reissner-Nordstrom solution and the interaction force between
two spherically symmetric charged particles | The physical representation of the general double-Reissner-Nordstrom solution
is obtained by rewriting the N=2 Breton-Manko-Aguilar electrostatic solution in
the Varzugin-Chistyakov parametrization (M_i, Q_i, R). A concise analytical
formula is derived for the interaction force between two arbitrary
Reissner-Nordstrom constituents, and an example of the equilibrium

710.2161 | Enhancement of surface activity in CO oxidation on Pt(110) through
spatiotemporal laser actuation | We explore the effect of spatiotemporally varying substrate temperature
profiles on the dynamics and resulting reaction rate enhancement for the
catalytic oxidation of CO on Pt(110). The catalytic surface is "addressed" by a
focused laser beam whose motion is computer-controlled. The averaged reaction
rate is observed to undergo a characteristic maximum as a function of the speed

710.2162 | Construction and Analysis of Projected Deformed Products | We introduce a deformed product construction for simple polytopes in terms of
lower-triangular block matrix representations. We further show how Gale duality
can be employed for the construction and for the analysis of deformed products
such that specified faces (e.g. all the k-faces) are ``strictly preserved''
under projection. Thus, starting from an arbitrary neighborly simplicial
(d-2)-polytope Q on n-1 vertices we construct a deformed n-cube, whose
projection to the last dcoordinates yields a neighborly cubical d-polytope. As
an extension of thecubical case, we construct matrix representations of
deformed products of(even) polygons (DPPs), which have a projection to d-space
that retains the complete (\lfloor \tfrac{d}{2} \rfloor - 1)-skeleton. In both
cases the combinatorial structure of the images under projection is completely
determined by the neighborly polytope Q: Our analysis provides explicit
combinatorial descriptions. This yields a multitude of combinatorially
different neighborly cubical polytopes and DPPs. As a special case, we obtain
simplified descriptions of the neighborly cubical polytopes of Joswig & Ziegler
(2000) as well as of the ``projected deformed products of polygons'' that were
announced by Ziegler (2004), a family of 4-polytopes whose ``fatness'' gets
arbitrarily close to 9.

partial wave dispersion relations are used to discuss $\pi\pi$ scattering

710.2164 | Quantum Gravitational Collapse and Hawking Radiation in 2+1 Dimensions | We develop the canonical theory of gravitational collapse in 2+1 dimensions
with a negative cosmological constant and obtain exact solutions of the
Wheeler--DeWitt equation regularized on a lattice. We employ these solutions to
derive the Hawking radiation from black holes formed in all models of dust
collapse. We obtain an (approximate) Planck spectrum near the horizon
characterized by the Hawking temperature $T_{\mathrm H}=\hbar\sqrt{G\Lambda
M}/2\pi$, where $M$ is the mass of a black hole that is presumed to form at the
center of the collapsing matter cloud and $-\Lambda$ is the cosmological
constant. Our solutions to the Wheeler-DeWitt equation are exact, so we are
able to reliably compute the greybody factors that result from going beyond the
near horizon region.

710.2166 | Local torus actions modeled on the standard representation | We introduce the notion of a local torus action modeled on the standard
representation (for simplicity, we call it a local torus action). It is a
generalization of a locally standard torus action and also an underlying
structure of a locally toric Lagrangian fibration. For a local torus action, we
define two invariants called a characteristic pair and an Euler class of the
orbit map, and prove that local torus actions are classified topologically by
them. As a corollary, we obtain a topological classification of locally
standard torus actions, which is a generalization of the topological
classification of quasi-toric manifolds by Davis and Januszkiewicz and of
effective two-dimensional torus actions on four-dimensional manifolds without
nontrivial finite stabilizers by Orlik and Raymond. We investigate locally
toric Lagrangian fibrations from the viewpoint of local torus actions. We give
a necessary and sufficient condition in order that a local torus action becomes
a locally toric Lagrangian fibration. Locally toric Lagrangian fibrations are
classified by Boucetta and Molino up to fiber-preserving symplectomorphisms. We
shall reprove the classification theorem of locally toric Lagrangian fibrations
by refining the proof of the classification theorem of local torus actions. We
also investigate the topology of a manifold equipped with a local torus action
when the Euler class of the orbit map vanishes.

710.2167 | The connection problem associated with a Selberg type integral and the
$q$-Racah polynomials | The connection problem associated with a Selberg type integral is solved. The
connection coefficients are given in terms of the $q$-Racah polynomials. As an
application of the explicit expression of the connection coefficients, examples
of the monodromy-invariant Hermitian form of non-diagonal type are presented.
It is noteworthy that such Hermitian forms are intimately related with the

710.217 | X-ray magnetic circular dichroism and photoemission study of the diluted
ferromagnetic semiconductor Zn$_{1-x}$Cr$_x$Te | We have performed x-ray magnetic circular dichroism (XMCD) and valence-band
photoemission studies of the diluted ferromagnetic semiconductor
Zn$_{1-x}$Cr$_x$Te. XMCD signals due to ferromagnetism were observed at the Cr
2p absorption edge. Comparison with atomic multiplet calculations suggests that
the magnetically active component of the Cr ion was divalent under the
tetrahedral crystal field with tetragonal distortion along the crystalline a-,
b-, and c-axes. In the valence-band spectra, spectral weight near the Fermi

Models | We study the properties and behaviour of the quasi-pseudospherical and
quasi-planar Szekeres models, obtain the regularity conditions, and analyse
their consequences. The quantities associated with "radius" and "mass" in the
quasi-spherical case must be understood in a different way for these cases. The
models with pseudospherical foliation can have spatial maxima and minima, but
no origins. The "mass" and "radius" functions may be one increasing and one
decreasing without causing shell crossings. This case most naturally describes
a snake-like, variable density void in a more gently varying inhomogeneous
background, although regions that develop an overdensity are also possible. The
Szekeres models with plane foliation can have neither spatial extrema nor
origins, cannot be spatially flat, and they cannot have more inhomogeneity than
the corresponding Ellis model, but a planar surface can be the boundary between
regions of spherical and pseudospherical foliation.

710.2172 | Direct current voltage induced by microwave signal in a ferromagnetic
wire | Experimental results of rectification of a constant wave radio frequency (RF)
current flowing in a single-layered ferromagnetic wire are presented. We show
that a detailed external magnetic field dependence of the RF current induced a
direct-current voltage spectrum. The mechanism of the rectification is
discussed in a term of the spin transfer torque, and the rectification is
closely related to resonant spin wave excitation with the assistant of the
spin-polarized RF current. The micromagnetic simulation taking into account the

710.2175 | High-redshift voids in the excursion set formalism | Voids are a dominant feature of the low-redshift galaxy distribution. Several
recent surveys have found evidence for the existence of large-scale structure
at high redshifts as well. We present analytic estimates of galaxy void sizes
at redshifts z ~ 5 - 10 using the excursion set formalism. We find that recent
narrow-band surveys at z ~ 5 - 6.5 should find voids with characteristic scales
of roughly 20 comoving Mpc and maximum diameters approaching 40 Mpc. This is
consistent with existing surveys, but a precise comparison is difficult because
of the relatively small volumes probed so far. At z ~ 7 - 10, we expect
characteristic void scales of ~ 14 - 20 comoving Mpc assuming that all galaxies
within dark matter haloes more massive than 10^10 M_sun are observable. We find
that these characteristic scales are similar to the sizes of empty regions
resulting from purely random fluctuations in the galaxy counts. As a result,
true large-scale structure will be difficult to observe at z ~ 7 - 10, unless
galaxies in haloes with masses less than ~ 10^9 M_sun are visible. Galaxy
surveys must be deep and only the largest voids will provide meaningful
information. Our model provides a convenient picture for estimating the
"worst-case" effects of cosmic variance on high-redshift galaxy surveys with
limited volumes.
| astro-ph | voids are a dominant feature of the lowredshift galaxy distribution several recent surveys have found evidence for the existence of largescale structure at high redshifts as well we present analytic estimates of galaxy void sizes at redshifts z 5 10 using the excursion set formalism we find that recent narrowband surveys at z 5 65 should find voids with characteristic scales of roughly 20 comoving mpc and maximum diameters approaching 40 mpc this is consistent with existing surveys but a precise comparison is difficult because of the relatively small volumes probed so far at z 7 10 we expect characteristic void scales of 14 20 comoving mpc assuming that all galaxies within dark matter haloes more massive than 1010 m_sun are observable we find that these characteristic scales are similar to the sizes of empty regions resulting from purely random fluctuations in the galaxy counts as a result true largescale structure will be difficult to observe at z 7 10 unless galaxies in haloes with masses less than 109 m_sun are visible galaxy surveys must be deep and only the largest voids will provide meaningful information our model provides a convenient picture for

710.2177 | QCD Analysis for Nuclear Parton Distributions in the Next to Leading
Order | A QCD analysis of the nuclear parton distributions and structure functions in
the NLO is performed by using the world data. By having bounded parton
distributions for a nuclear with atomic number A, we can obtain the nuclear
structure function in x space. Our results for nuclear structure function ratio

710.2178 | Zel'dovich-Starobinsky Effect in Atomic Bose-Einstein Condensates:
Analogy to Kerr Black Hole | We consider circular motion of a heavy object in an atomic Bose-Einstein
condensate (BEC) at $T=0{\rm K}$. Even if the linear velocity of the object is
smaller than the Landau critical velocity, the object may radiate
quasiparticles and thus experience the quantum friction. The radiation process
is similar to Zel'dovich-Starobinskii (ZS) effect -- the radiation by a
rotating black hole. This analogy emerges when one introduces the effective
acoustic metric for quasiparticles. In the rotating frame this metric has an
ergosurface, which is similar to the ergosurface in the metric of a rotating
black hole. In a finite size BEC, the quasiparticle creation takes place when
the ergosurface is within the condensate and occurs via quantum tunneling from
the object into the ergoregion. The dependence of the radiation rate on the
position of the ergosurface is investigated.

710.2179 | Cluster simulation of two-dimensional relativistic fermions | The (discrete) Gross-Neveu model is studied in a lattice realization with an
N-component Majorana Wilson fermion field. It has an internal O(N) symmetry in
addition to the euclidean lattice symmetries. The discrete chiral symmetry for
vanishing mass is expected to emerge in the continuum limit only. The lattice
theory is first recast in terms of two-valued bosonic link variables (dimers).
In this representation, which coincides with the loop representation obtained
earlier by Gattringer with the help of eight-vertex-models, the Boltzmann
weight is essentially positive. While standard local updates are possible in
this form we construct a further exact transformation where we generate dimer
configurations as Peierls contours of an Ising model with a local action
residing on plaquettes. For this model a Swendsen-Wang type cluster algorithm
is constructed. At vanishing coupling it is numerically demonstrated to almost
completely eliminate critical slowing down. Although further tests are

710.2181 | Generalized Interpolation Material Point Approach to High Melting
Explosive with Cavities Under Shock | Criterion for contacting is critically important for the Generalized
Interpolation Material Point(GIMP) method. We present an improved criterion by
adding a switching function. With the method dynamical response of high melting
explosive(HMX) with cavities under shock is investigated. The physical model
used in the present work is an elastic-to-plastic and thermal-dynamical model
with Mie-Gr\"uneissen equation of state. We mainly concern the influence of
various parameters, including the impacting velocity $v$, cavity size $R$, etc,
to the dynamical and thermodynamical behaviors of the material. For the
colliding of two bodies with a cavity in each, a secondary impacting is
observed. Correspondingly, the separation distance $D$ of the two bodies has a
maximum value $D_{\max}$ in between the initial and second impacts. When the
initial impacting velocity $v$ is not large enough, the cavity collapses in a
nearly symmetric fashion, the maximum separation distance $D_{\max}$ increases
with $v$. When the initial shock wave is strong enough to collapse the cavity
asymmetrically along the shock direction, the variation of $D_{\max}$ with $v$
does not show monotonic behavior. Our numerical results show clear indication
that the existence of cavities in explosive helps the creation of ``hot
spots''.

710.2183 | Strong consistency of the maximum likelihood estimator for finite
mixtures of location-scale distributions when penalty is imposed on the
ratios of the scale parameters | In finite mixtures of location-scale distributions, if there is no constraint
or penalty on the parameters, then the maximum likelihood estimator does not
exist because the likelihood is unbounded. To avoid this problem, we consider a
penalized likelihood, where the penalty is a function of the minimum of the
ratios of the scale parameters and the sample size. It is shown that the
penalized maximum likelihood estimator is strongly consistent. We also analyze
the consistency of a penalized maximum likelihood estimator where the penalty
is imposed on the scale parameters themselves.

710.2185 | A new nucleon resonance in eta photoproduction | We present in this talk recent investigations on the nucleon-like resonance
N*(1675) newly found in eta photoproduction by the GRAAL, Tohoku LNS-gamma and
CB-ELSA collaborations. We focus on the production mechanism of the N*(1675),
examining its spin and parity theoretically within the framework of the
effective Lagrangian method. We expliucitly consider D_{13}(1520),
S_{11}(1535), S_{11}(1650), D_{15}(1675), P_{11}(1710), P_{13}(1720) as well as
possible background contributions. We calculate the differential cross sections
and beam asymmetries for the neutron and proton targets. It turns out that
there is manifest isospin asymmetry in eta photoproduction, which can be
explained by the asymmetry in the transition magnetic moments: mu_{gamma p p*}
=<mu_{gamma n n*}. Moreover, we find that the spin-1/2 state is preferred and
this observation implies that the new resonance may be identified as a
non-strangeness member of the baryon antidecuplet.

710.2187 | Theoretical analysis for the apparent discrepancy between pbarp and pp
data in charged particle forward-backward multiplicity correlations | The strength of charged particle forward-backward multiplicity correlation in
pbar+p and p+p collisions at s^1/2 = 200 GeV is studied by PYTHIA 6.4 and
compared to the UA5 and STAR data correspondingly. It is turned out that a
factor of 3-4 apparent discrepancy between UA5 and STAR data can be attributed
to the differences in detector acceptances and observing bin interval in both
experiments. A mixed event method is introduced and used to calculate the
statistical correlation strength and the dynamical correlation strengths
stemming from the charge conservation, four- momentum conservation, and decay,
respectively. It seems that the statistical correlation is much larger than
dynamical one and the charge conservation, four-momentum conservation and decay
may account for most part of the dynamical correlation. In addition, we have
also calculated the correlation strength by fitting the charged particle
multiplicity distribution from PYTHIA to the Negative Binomial Distribution and
found that the result agrees well with the correlation strength calculated by
mixed events.

710.2188 | High temperature expansion in supersymmetric matrix quantum mechanics | We formulate the high temperature expansion in supersymmetric matrix quantum
mechanics with 4, 8 and 16 supercharges. The models can be obtained by
dimensionally reducing N=1 U(N) super Yang-Mills theory in D=4,6,10 to 1
dimension, respectively. While the non-zero frequency modes become weakly
coupled at high temperature, the zero modes remain strongly coupled. We find,
however, that the integration over the zero modes that remains after
integrating out all the non-zero modes perturbatively, reduces to the
evaluation of connected Green's functions in the bosonic IKKT model. We perform
Monte Carlo simulation to compute these Green's functions, which are then used
to obtain the coefficients of the high temperature expansion for various
quantities up to the next-leading order. Our results nicely reproduce the
asymptotic behaviors of the recent simulation results at finite temperature. In
particular, the fermionic matrices, which decouple at the leading order, give
rise to substantial effects at the next-leading order, reflecting finite
temperature behaviors qualitatively different from the corresponding models
without fermions.

710.2189 | Strong Interactive Massive Particles from a Strong Coupled Theory | Minimal walking technicolor models can provide a nontrivial solution for
cosmological dark matter, if the lightest technibaryon is doubly charged.
Technibaryon asymmetry generated in the early Universe is related to baryon
asymmetry and it is possible to create excess of techniparticles with charge
(-2). These excessive techniparticles are all captured by $^4He$, creating
\emph{techni-O-helium} $tOHe$ ``atoms'', as soon as $^4He$ is formed in Big
Bang Nucleosynthesis. The interaction of techni-O-helium with nuclei opens new
paths to the creation of heavy nuclei in Big Bang Nucleosynthesis. Due to the
large mass of technibaryons, the $tOHe$ ``atomic'' gas decouples from the
baryonic matter and plays the role of dark matter in large scale structure
formation, while structures in small scales are suppressed. Nuclear
interactions with matter slow down cosmic techni-O-helium in Earth below the
threshold of underground dark matter detectors, thus escaping severe CDMS
constraints. On the other hand, these nuclear interactions are not sufficiently
strong to exclude this form of Strongly Interactive Massive Particles by
constraints from the XQC experiment. Experimental tests of this hypothesis are
possible in search for $tOHe$ in balloon-borne experiments (or on the ground)
and for its charged techniparticle constituents in cosmic rays and
accelerators. The $tOHe$ ``atoms'' can cause cold nuclear transformations in
matter and might form anomalous isotopes, offering possible ways to exclude (or
prove?) their existence.

Completing the dataset | The long-slit spectra obtained along the minor axis, offset major axis and
diagonal axis are presented for 12 E and S0 galaxies of the Coma cluster drawn
from a magnitude-limited sample studied before. The rotation curves, velocity
dispersion profiles and the H_3 and H_4 coefficients of the Hermite
decomposition of the line of sight velocity distribution are derived. The
radial profiles of the Hbeta, Mg, and Fe line strength indices are measured
too. In addition, the surface photometry of the central regions of a subsample
of 4 galaxies recently obtained with Hubble Space Telescope is presented. The
data will be used to construct dynamical models of the galaxies and study their
stellar populations.

710.2191 | Three-Dimensional Simulations of Standing Accretion Shock Instability in
Core-Collapse Supernovae | We have studied non-axisymmetric standing accretion shock instability, or
SASI, by 3D hydrodynamical simulations. This is an extention of our previous
study on axisymmetric SASI. We have prepared a spherically symmetric and steady
accretion flow through a standing shock wave onto a proto-neutron star, taking
into account a realistic equation of state and neutrino heating and cooling.
This unperturbed model is supposed to represent approximately the typical
post-bounce phase of core-collapse supernovae. We then have added a small
perturbation (~1%) to the radial velocity and computed the ensuing evolutions.
Not only axisymmetric but non-axisymmetric perturbations have been also
imposed. We have applied mode analysis to the non-spherical deformation of the
shock surface, using the spherical harmonics. We have found that (1) the growth
rates of SASI are degenerate with respect to the azimuthal index m of the
spherical harmonics Y_l^m, just as expected for a spherically symmetric
background, (2) nonlinear mode couplings produce only m=0 modes for the
axisymmetric perturbations, whereas m=!0 modes are also generated in the
non-axisymmetric cases according to the selection rule for the quadratic
couplings, (3) the nonlinear saturation level of each mode is lower in general
for 3D than for 2D because a larger number of modes are contributing to
turbulence in 3D, (4) low l modes are dominant in the nonlinear phase, (5) the
equi-partition is nearly established among different m modes in the nonlinear
phase, (6) the spectra with respect to l obey power laws with a slope slightly
steeper for 3D, and (7) although these features are common to the models with
and without a shock revival at the end of simulation, the dominance of low l
modes is more remarkable in the models with a shock revival.

710.2193 | Can low metallicity binaries avoid merging? | Rapid mass transfer in a binary system can drive the accreting star out of
thermal equilibrium, causing it to expand. This can lead to a contact system,
strong mass loss from the system and possibly merging of the two stars. In low
metallicity stars the timescale for heat transport is shorter due to the lower
opacity. The accreting star can therefore restore thermal equilibrium more
quickly and possibly avoid contact.
We investigate the effect of accretion onto main sequence stars with
radiative envelopes with different metallicities. We find that a low
metallicity (Z<0.001), 4 solar mass star can endure a 10 to 30 times higher
accretion rate before it reaches a certain radius than a star at solar
metallicity. This could imply that up to two times fewer systems come into
contact during rapid mass transfer when we compare low metallicity. This factor
is uncertain due to the unknown distribution of binary parameters and the
dependence of the mass transfer timescale on metallicity. In a forthcoming
paper we will present analytic fits to models of accreting stars at various
metallicities intended for the use in population synthesis models.

710.2195 | A Statistical Description of Parametric Instabilities with an Incoherent
Pump | The effect on parametric instability growth of pump wave incoherence is
treated by deriving a set of equations governing the space-time evolution of
the ensemble-average coupled-mode amplitudes and intensities. Particular
attention is paid to establishing the regions of validity of the statistical
description. Thresholds, growth rates, and amplification rates are given for
both spatially and temporally incoherent pump waves. Both absolutely and
convectively unstable modes are considered. The statistical results are
verified where appropriate by numerical integration of the coupled-mode
equations with different models of pump incoherence.

710.2197 | Quasi-exact Solvability of Dirac Equations | We present a general procedure for determining quasi-exact solvability of the
Dirac and the Pauli equation with an underlying $sl(2)$ symmetry. This
procedure makes full use of the close connection between quasi-exactly solvable

710.2198 | Disorder-dominated phases of random systems : relations between tails
exponents and scaling exponents | We consider various random models (directed polymer, ferromagnetic random
Potts model, Ising spin-glasses) in their disorder-dominated phases, where the
free-energy cost $F(L)$ of an excitation of length $L$ present fluctuations
that grow as a power-law $\Delta F(L) \sim L^{\omega}$ with the so-called
droplet exponent $\omega>0$. We study the tails of the probability distribution
$\Pi(x)$ of the rescaled free-energy cost $x= \frac{F_L-
\bar{F_L}}{L^{\omega}}$, which are governed by two exponents $(\eta_-,\eta_+)$
defined by $\ln \Pi(x \to \pm \infty) \sim - | x |^{\eta_{\pm}}$. The aim of
this paper is to establish simple relations between these tail exponents
$(\eta_-,\eta_+) $ and the droplet exponent $\omega$. We first prove these
relations for disordered models on diamond hierarchical lattices where exact
renormalizations exist for the probability distribution $\Pi(x)$. We then
interpret these relations via an analysis of the measure of the rare disorder
configurations governing the tails. Our conclusion is that these relations,
when expressed in terms of the dimensions of the bulk and of the excitation
surface are actually valid for general lattices.

710.2199 | Jets or high velocity flows revealed in high-cadence spectrometer and
imager co-observations? | We report on active region EUV dynamic events observed simultaneously at
high-cadence with SUMER/SoHO and TRACE. Although the features appear in the
TRACE Fe ix/x 171A images as jets seen in projection on the solar disk, the
SUMER spectral line profiles suggest that the plasma has been driven along a
curved large scale magnetic structure, a pre-existing loop. The SUMER
observations were carried out in spectral lines covering a large temperature
range from 10^4 K to 10^6 K. The spectral analysis revealed that a sudden
heating from an energy deposition is followed by a high velocity plasma flow.
The Doppler velocities were found to be in the range from 90 to 160 km/s. The
heating process has a duration which is below the SUMER exposure time of 25 s
while the lifetime of the events is from 5 to 15 min. The additional check on
soft X-ray Yohkoh images shows that the features most probably reach 3 MK

710.22 | Scale decomposition of molecular beam epitaxy | In this work, a study of epitaxial growth was carried out by means of
wavelets formalism. We showed the existence of a dynamic scaling form in
wavelet discriminated linear MBE equation where diffusion and noise are the
dominant effects. We determined simple and exact scaling functions involving
the scale of the wavelets when the system size is set to infinity. Exponents
were determined for both, correlated and uncorrelated noise. The wavelet
methodology was applied to a computer model simulating the linear epitaxial
growth; the results showed a very good agreement with analytical formulation.
We also considered epitaxial growth with the additional Ehrlich$-$Schwoebel
effect. We characterized the coarsening of mounds formed on the surface during
the nonlinear phase using the wavelet power spectrum. The latter have an
advantage over other methods in the sense that one can track the coarsening in
both frequency (or scale) space and real space simultaneously. We showed that
the averaged wavelet power spectrum (also called scalegram) over all the
positions on the surface profile, identified the existence of a dominant scale
$a^*$, which increases with time following a power law relation of the form
$a^* \sim t^n$, where $n\simeq 1/3$.

710.2201 | Heavy-strange meson decay constants in the continuum limit of quenched
QCD | We improve a previous quenched result for heavy-light pseudoscalar meson
decay constants with the light quark taken to be the strange quark. A finer
lattice resolution (a ~ 0.05 fm) in the continuum limit extrapolation of the
data computed in the static approximation is included. We also give further
details concerning the techniques used in order to keep the statistical and
systematic errors at large lattice sizes L/a under control. Our final result,
obtained by combining these data with determinations of the decay constant for
pseudoscalar mesons around the D_s, follows nicely the qualitative expectation
of the 1/m-expansion with a (relative) 1/m-term of about -0.5 GeV/m_PS. At the

710.2202 | Searches for Extra Dimensions and for Heavy Resonances in Dilepton,
Diphoton, Electron + Photon and Electron + Missing ET Final States with the
D0 Detector | The high mass spectrum of lepton and photon pairs is sensitive to a broad
array of new physics. Examples include searches for extra dimensions in the
dielectron and diphoton channels. A direct search for electron compositeness is
possible in the production of excited electrons decaying into an electron and a
photon. In addition, the electron plus missing transverse energy data sample
can be searched for a W' boson. Latest results in searches in the high mass
dielectron, diphoton, electron plus photon, and electron plus missing
transverse energy channels obtained by the D0 experiment at the Tevatron are
reported, using a data set corresponding to an integrated luminosity of about 1
inverse femtobarn. Since no significant excess is observed in the data in all
cases, limits are set which improve on previous searches.

710.2205 | Stabilizing quantum metastable states in a time-periodic potential | In this talk we present a model to demonstrate how time-periodic potential
can be used to manipulate quantum metastability of a system. We study
metastability of a particle trapped in a well with a time-periodically
oscillating barrier in the Floquet formalism. It is shown that the oscillating
barrier causes the system to decay faster in general. However, avoided
crossings of metastable states can occur with the less stable states crossing
over to the more stable ones. If in the static well there exists a bound state,
then it is possible to stabilize a metastable state by adiabatically increasing
the oscillating frequency of the barrier so that the unstable state eventually
cross-over to the stable bound state. It is also found that increasing the
amplitude of the oscillating field may change a direct crossing of states into
an avoided one. Hence, one can manipulate the stability of different states in
a quantum potential by a combination of adiabatic changes of the frequency and
the amplitude of the oscillating barrier.

of any Standard Model background, and the supersymmetric backgrounds are small.
Such a signal can be experimentally observable under certain conditions which
are possible to obtain in an anomaly-mediated supersymmetry breaking scenario.
Information on a particular combination of the neutrino masses and mixing
angles can also be extracted through the observation of this signal.
Sneutrino-antisneutrino mixing at the LHC is currently under study, and
asymmetry considerations seem promising there.

710.2208 | On Nurowski's conformal structure associated to a generic rank two
distribution in dimension five | For a generic distribution of rank two on a manifold $M$ of dimension five,
we introduce the notion of a generalized contact form. To such a form we
associate a generalized Reeb field and a partial connection. From these data,
we explicitly constructed a pseudo--Riemannian metric on $M$ of split
signature. We prove that a change of the generalized contact form only leads to
a conformal rescaling of this metric, so the corresponding conformal class is
intrinsic to the distribution. In the second part of the article, we relate
this conformal class to the canonical Cartan connection associated to the
distribution. This is used to prove that it coincides with the conformal class
constructed by Nurowski.

710.221 | Effects of Inflation on a Cosmic String Loop Population | We study the evolution of simple cosmic string loop solutions in an
inflationary universe. We show, for the particular case of circular loops, that
periodic solutions do exist in a de Sitter universe, below a critical loop
radius $R_c H=1/2$. On the other hand, larger loops freeze in comoving
coordinates, and we explicitly show that they can survive more $e$-foldings of
inflation than point-like objects. We discuss the implications of these
findings for the survival of realistic cosmic string loops during inflation,
and for the general characteristics of post-inflationary cosmic string
networks. We also consider the analogous solutions for domain walls, in which
case the critical radius is $R_c H=2/3$.

710.2212 | Probing Universal Extra Dimensions through rare decays induced by $b \to
s$ transition | A few $B_{d,s}$ and $\Lambda_b$ decays induced by $b \to s$ transition are
studied in the Standard Model and in the framework of the Appelquist, Cheng and

710.2216 | The dying rabbit problem revisited | In this paper we study a generalization of the Fibonacci sequence in which
rabbits are mortal and take more that two months to become mature. In
particular we give a general recurrence relation for these sequences (improving
the work in the paper Hoggatt, V. E., Jr.; Lind, D. A. "The dying rabbit
problem". Fibonacci Quart. 7 1969 no. 5, 482--487) and we calculate explicitly
their general term (extending the work in the paper Miles, E. P., Jr.
Generalized Fibonacci numbers and associated matrices. Amer. Math. Monthly 67
1960 745--752). In passing, and as a technical requirement, we also study the
behavior of the positive real roots of the characteristic polynomial of the
considered sequences.

selection rules, we have probed the superconducting gap in the nodal and

antinodal peak detected in the superconducting state is not related to the
critical temperature Tc and that signatures of superconductivity disappear in
the nodal regions. Our experimental findings advocate in favor of gapless arcs
around the nodes. The breakdown of the relationship between the antinodal gap

710.2219 | Forces and momenta caused by electromagnetic waves in magnetoelectric
media | We analyse the propagation of electromagnetic waves in magnetoelectric media.
Recently, Feigel has predicted that such a medium may ``extract momentum from
vacuum" in the sense that the total momentum of the virtual waves (vacuum
fluctuations of the electromagnetic field) is nontrivial. Our aim is to check
the feasibility of this effect. The crucial point in our study is an assumption
of the finite size of the magnetoelectric sample, which allows us to reduce the
calculation of the momenta and forces of the electromagnetic waves acting on
the sample to the vacuum region outside of the medium. In this framework, we
demonstrate that, in contrast to Feigel, the total force caused by the virtual
is zero, with an appropriate count of the modes that should be taken into
account in this effect. Furthermore, we find that the two irreducible parts of
the magnetoelectric matrix behave differently in the possible Feigel effect.
Going beyond the original scheme of the virtual electromagnetic waves, we
propose an experimental scheme which is suitable for the measurement of the
magnetoelectric susceptibilities of the medium with the help of real
electromagnetic waves.

710.222 | Quantum phases of mixtures of atoms and molecules on optical lattices | We investigate the phase diagram of a two-species Bose-Hubbard model
including a conversion term, by which two particles from the first species can
be converted into one particle of the second species, and vice-versa. The model
can be related to ultra-cold atom experiments in which a Feshbach resonance
produces long-lived bound states viewed as diatomic molecules. The model is
solved exactly by means of Quantum Monte Carlo simulations. We show than an
"inversion of population" occurs, depending on the parameters, where the second
species becomes more numerous than the first species. The model also exhibits
an exotic incompressible "Super-Mott" phase where the particles from both
species can flow with signs of superfluidity, but without global supercurrent.

710.2221 | LAMBDA: Large Area Modular BaF2 Detector Array for the measurement of
high energy gamma rays | A large BaF2 detector array along with its dedicated CAMAC electronics and
VME based data acquisition system has been designed, constructed and installed
successfully at VECC, Kolkata for studying high energy gamma rays (E>8 MeV).
The array consists of 162 detector elements. The detectors were fabricated from
bare barium fluoride crystals (each measuring 35 cm in length and having
cross-sectional area of 3.5 cm X 3.5 cm X 35.0 cm). The basic properties of the
detectors (energy resolution, time resolution, efficiency, uniformity, fast to
slow ratio etc.) were studied exhaustively. Complete GEANT3 monte carlo
simulations were performed to optimize the detector design and also to generate
the response function. The detector system has been used successfully to
measure high energy photons from 113Sb, formed by bombarding 145 and 160 MeV
20Ne beams on a 93Nb target. The measured experimental spectra are in good
agreement with those from a modified version of the statistical model code
CASCADE. In this paper, we present the complete description of this detector
array along with its in-beam performance.

710.2222 | Dielectric Susceptibility and Heat Capacity of Ultra-Cold Glasses in
Magnetic Field | Recent experiments demonstrated unexpected, even intriguing properties of
certain glassy materials in magnetic field at low temperatures. We have studied
the magnetic field dependence of the static dielectric susceptibility and the
heat capacity of glasses at low temperatures. We present a theory in which we
consider the coupling of the tunnelling motion to nuclear quadrupoles in order
to evaluate the static dielectric susceptibility. In the limit of weak magnetic
field we find the resonant part of the susceptibility increasing like $B^2$
while for the large magnetic field it behaves as 1/B. In the same manner we
consider the coupling of the tunnelling motion to nuclear quadrupoles and
angular momentum of tunnelling particles in order to find the heat capacity.
Our results show the Schotky peak for the angular momentum part, and $B^2$
dependence for nuclear quadrupoles part of heat capacity, respectively. We

710.2225 | Dust in the wind: Crystalline silicates, corundum and periclase in PG
2112+059 | We have determined the mineralogical composition of dust in the Broad
Absorption Line (BAL) quasar PG 2112+059 using mid-infrared spectroscopy
obtained with the Spitzer Space Telescope. From spectral fitting of the solid
state features, we find evidence for Mg-rich amorphous silicates with olivine
stoichiometry, as well as the first detection of corundum (Al_2O_3) and
periclase (MgO) in quasars. This mixed composition provides the first direct
evidence for a clumpy density structure of the grain forming region. The
silicates in total encompass 56.5% of the identified dust mass, while corundum

fractions is observed for periclase ranging from 2.7% in the most conservative
case to 9% in a less constrained continuum. In addition, we identify a feature
at 11.2 micron as the crystalline silicate forsterite, with only a minor
contribution from polycyclic aromatic hydrocarbons. The 5% crystalline silicate
fraction requires high temperatures such as those found in the immediate quasar
environment in order to counteract rapid destruction from cosmic rays.

710.2226 | Functional biases in GRB's spectral parameter correlations | Gamma Ray Bursts (GRBs) show evidence of different spectral shapes, light
curves, duration, host galaxies and they explode within a wide redshift range.
However, the most of them seems to follow very tight correlations among some
observed quantities relating to their energetic. If true, these correlations
have significant implications on burst physics, giving constraints on
theoretical models. Moreover, several suggestions have been made to use these
correlations in order to calibrate GRBs as standard candles and to constrain
the cosmological parameters. We investigate the cosmological relation between
low energy $\alpha$ index in GRBs prompt spectra and the redshift $z$. We
present a statistical analysis of the relation between the total isotropic
energy $E_{iso}$ and the peak energy $E_p$ (also known as Amati relation) in
GRBs spectra searching for possible functional biases. Possible implications on
the $E_{iso}$ vs $E_p$ relation of the $\alpha$ vs $(1+z)$ correlation are
evaluated. We used MonteCarlo simulations and the boostrap method to evaluate
how large are the effects of functional biases on the $E_{iso}$ vs $E_p$. We
show that high values of the linear correlation coefficent, up to about 0.8, in
the $E_{iso}$ vs $E_p$ relation are obtained for random generated samples of
GRBs, confirming the relevance of functional biases. Astrophysical consequences
from $E_{iso}$ vs $E_p$ relation are then to be revised after a more accurate
and possibly bias free analysis.

710.2227 | A System for Predicting Subcellular Localization of Yeast Genome Using
Neural Network | The subcellular location of a protein can provide valuable information about
its function. With the rapid increase of sequenced genomic data, the need for
an automated and accurate tool to predict subcellular localization becomes
increasingly important. Many efforts have been made to predict protein
subcellular localization. This paper aims to merge the artificial neural
networks and bioinformatics to predict the location of protein in yeast genome.
We introduce a new subcellular prediction method based on a backpropagation

710.2229 | Precision for B-meson matrix elements | We demonstrate how HQET and the Step Scaling Method for B-physics, pioneered
by the Tor Vergata group, can be combined to reach a further improved
precision. The observables considered are the mass of the b-quark and the
B_s-meson decay constant. The demonstration is carried out in quenched lattice
QCD. We start from a small volume, where one can use a standard O(a)-improved
relativistic action for the b-quark, and compute two step scaling functions
which relate the observables to the large volume ones. In all steps we
extrapolate to the continuum limit, separately in HQET and in QCD for masses
below m_b. The physical point m_b is then reached by an interpolation of the
continuum results in 1/m. The essential, expected and verified, feature is that
the step scaling fuctions have a weak mass-dependence resulting in an easy
interpolation to the physical point. With r_0=0.5fm and the experimental B_s
and K masses as input, we find F_Bs=191(6)MeV and the renormalization group

phenomenology of the unparticle physics associated with an exact scale
invariant sector possessing a non-trivial infrared fixed point at a high energy
scale. We give highlights on the motivations of unparticle and derivation of
the phase space and the unparticle propagator. We study two categories of
phenomenology: (i) real emission of unparticle that gives rise to peculiar
missing energy signatures, and (ii) virtual exchange of unparticle that
interferes with the standard model amplitudes.

710.2231 | Comparison and Combination of State-of-the-art Techniques for
Handwritten Character Recognition: Topping the MNIST Benchmark | Although the recognition of isolated handwritten digits has been a research
topic for many years, it continues to be of interest for the research community
and for commercial applications. We show that despite the maturity of the
field, different approaches still deliver results that vary enough to allow
improvements by using their combination. We do so by choosing four
well-motivated state-of-the-art recognition systems for which results on the
standard MNIST benchmark are available. When comparing the errors made, we
observe that the errors made differ between all four systems, suggesting the
use of classifier combination. We then determine the error rate of a
hypothetical system that combines the output of the four systems. The result
obtained in this manner is an error rate of 0.35% on the MNIST data, the best

Binaries | We have detected 523 sources in a survey of the Small Magellanic Cloud (SMC)
Wing with Chandra. By cross-correlating the X-ray data with optical and
near-infrared catalogues we have found 300 matches. Using a technique that
combines X-ray colours and X-ray to optical flux ratios we have been able to
assign preliminary classifications to 265 of the objects. Our identifications
include four pulsars, one high-mass X-ray binary (HMXB) candidate, 34 stars and
185 active galactic nuclei (AGNs). In addition, we have classified 32 sources
as 'hard' AGNs which are likely absorbed by local gas and dust, and nine 'soft'
AGNs whose nature is still unclear. Considering the abundance of HMXBs
discovered so far in the Bar of the SMC the number that we have detected in the
Wing is low.

g_{KK} have enhanced couplings to the right-handed quarks. In the absence of a
gg g_{KK} coupling in these models, the single production of a g_{KK} from an
initial gg state is not possible. The search for other production mechanisms at
the LHC, therefore, becomes important. We suggest that the associated
production of a g_{KK} with a t t(bar) pair is such a mechanism. Our study
shows that through this process the LHC can probe KK gluon masses in the range
of 2.8 -- 2.9 TeV.

710.2235 | Proteins in a shear flow | The conformational dynamics of a single protein molecule in a shear flow is
investigated using Brownian dynamics simulations. A structure-based coarse
grained model of a protein is used. We consider two proteins, ubiquitin and
integrin, and find that at moderate shear rates they unfold through a sequence
of metastable states - a pattern which is distinct from a smooth unraveling
found in homopolymers. Full unfolding occurs only at very large shear rates.
Furthermore, the hydrodynamic interactions between the amino acids are shown to
hinder the shear flow unfolding. The characteristics of the unfolding process
depend on whether a protein is anchored or not, and if it is, on the choice of
an anchoring point.

710.2237 | Formation, fractionation and excitation of carbon monoxide in diffuse
clouds | Aims: Our aims are threefold: a) To compare the $uv$ and mm-wave results; b)
to interpret 13CO and 12CO abundances in terms of the physical processes which
separately and jointly determine them; c) to interpret observed J=1-0
rotational excitation and line brightness in terms of ambient gas properties.
Methods: A simple phenomenological model of CO formation as the immediate
descendant of quiescently-recombining HCO+ is used to study the accumulation,
fractionation and rotational excitation of CO in more explicit and detailed
models of H2-bearing diffuse/H I clouds
Results: The variation of N(CO) with N(H2) is explained by quiescent
recombination of a steady fraction n(HCO+)/n(H2) = 2 x 10^{-9}. Observed
N(12CO))/N(13CO) ratios generally do not require a special chemistry but result
from competing processes and do not provide much insight into the local gas
properties, especially the temperature. J=1-0 CO line brightnesses directly
represent N(CO), not N(H2), so the CO-H2 conversion factor varies widely; it
attains typical values at N(12CO) \la 10^{16}cm^{-2}. Models of CO rotational
excitation account for the line brightnesses and CO-H2 conversion factors but
readily reproduce the observed excitation temperatures and optical depths of
the rotational transitions only if excitation by H-atoms is weak -- as seems to
be the case for the very most recent calculations of these excitation rates.

710.224 | The radiative lifetime of metastable CO ($a^3\Pi, v=0$) | We present a combined experimental and theoretical study on the radiative
lifetime of CO in the $a^3\Pi_{1,2}, v=0$ state. CO molecules in a beam are
prepared in selected rotational levels of this metastable state,
Stark-decelerated and electrostatically trapped. From the phosphorescence decay
in the trap, the radiative lifetime is measured to be $2.63\pm0.03$ ms for the
$a^3\Pi_1, v=0, J=1$ level. From spin-orbit coupling between the $a^3\Pi$ and
the $A^1\Pi$ state a 20% longer radiative lifetime of 3.16 ms is calculated for
this level. It is concluded that coupling to other $^1\Pi$ states contributes
to the observed phosphorescence rate of metastable CO.

710.2241 | A Catalog of Galaxy Clusters Observed by XMM-Newton | Aims: We present a uniform catalog of the images and radial profiles of the
temperature, abundance, and brightness for 70 clusters of galaxies observed by
XMM-Newton.
Methods: We use a new "first principles" approach to the modeling and removal
of the background components; the quiescent particle background, the cosmic
diffuse emission, the soft proton contamination, and the solar wind charge
exchange emission. Each of the background components demonstrate significant
spectral variability, several have spatial distributions that are not described
by the photon vignetting function, and all except for the cosmic diffuse
emission are temporally variable. Because these backgrounds strongly affect the
analysis of low surface brightness objects, we provide a detailed description
our methods of identification, characterization, and removal.
Results: We have applied these methods to a large collection of XMM-Newton
observations of clusters of galaxies and present the resulting catalog. We find
significant systematic differences between the Chandra and XMM-Newton
temperatures.

a normalized rank 2 vector bundle E on P^3 which force E to split, and finds
therefore strategic levels of non-vanishing for a non-split bundle. The present
conditions improve other conditions known in the literature and are obtained
with simple computations on the Euler characteristic function, avoiding the
speciality lemma, Barth's restriction theorem, the discriminat property, and
other heavy tools.

710.2243 | Edge Local Complementation and Equivalence of Binary Linear Codes | Orbits of graphs under the operation edge local complementation (ELC) are
defined. We show that the ELC orbit of a bipartite graph corresponds to the
equivalence class of a binary linear code. The information sets and the minimum
distance of a code can be derived from the corresponding ELC orbit. By
extending earlier results on local complementation (LC) orbits, we classify the
ELC orbits of all graphs on up to 12 vertices. We also give a new method for
classifying binary linear codes, with running time comparable to the best known
algorithm.

710.2245 | Size, power and false discovery rates | Modern scientific technology has provided a new class of large-scale
simultaneous inference problems, with thousands of hypothesis tests to consider
at the same time. Microarrays epitomize this type of technology, but similar
situations arise in proteomics, spectroscopy, imaging, and social science
surveys. This paper uses false discovery rate methods to carry out both size
and power calculations on large-scale problems. A simple empirical Bayes
approach allows the false discovery rate (fdr) analysis to proceed with a
minimum of frequentist or Bayesian modeling assumptions. Closed-form accuracy
formulas are derived for estimated false discovery rates, and used to compare
different methodologies: local or tail-area fdr's, theoretical, permutation, or
empirical null hypothesis estimates. Two microarray data sets as well as
simulations are used to evaluate the methodology, the power diagnostics showing

710.2246 | Probing the Slope of Cluster Mass Profile with Gravitational Einstein
Rings: Application to Abell 1689 | The strong lensing modelling of gravitational ``rings'' formed around massive
galaxies is sensitive to the amplitude of the external shear and convergence
produced by nearby mass condensations. In current wide field surveys, it is now
possible to find out a large number of rings, typically 10 gravitational rings
per square degree. We propose here, to systematically study gravitational rings
around galaxy clusters to probe the cluster mass profile beyond the cluster
strong lensing regions. For cluster of galaxies with multiple arc systems, we
show that rings found at various distances from the cluster centre can improve
the modelling by constraining the slope of the cluster mass profile. We outline
the principle of the method with simple numerical simulations and we apply it
to 3 rings discovered recently in Abell~1689. In particular, the lens modelling
of the 3 rings confirms that the cluster is bimodal, and favours a slope of the
mass profile steeper than isothermal at a cluster radius $\sim 300 \kpc$. These
results are compared with previous lens modelling of Abell~1689 including weak
lensing analysis. Because of the difficulty arising from the complex mass
distribution in Abell~1689, we argue that the ring method will be better
implemented on simpler and relaxed clusters.

710.2247 | New Companions for the lonely Crab? VHE emission from young pulsar wind
nebulae revealed by H.E.S.S | The deeper and more extended survey of the central parts of the Galactic
Plane by H.E.S.S. during 2005-2007 has revealed a number of new point-like, as
well as, extended sources. Two point-like sources can be associated to two
remarkable objects around "Crab-like" young and energetic pulsars in our

710.2248 | RXTE confirmation of the Intermediate Polar status of Swift J0732.5-1331 | Aims. We intend to establish the X-ray properties of Swift J0732.5-1331 and
therefore confirm its status as an intermediate polar. Method. We analysed
36,240 s of X-ray data from RXTE. Frequency analysis was used to constrain
temporal variations and spectral analysis used to characterise the emission and
absorption properties. Results. The X-ray spin period is confirmed to be
512.4(3) s with a strong first harmonic. No modulation is detected at the
candidate orbital period of 5.6 h, but a coherent modulation is present at the
candidate 11.3 h period. The spectrum is consistent with a 37 keV
bremsstrahlung continuum with an iron line at 6.4 keV absorbed by an equivalent
hydrogen column density of around 10^22 atoms cm^-2. Conclusions. Swift
J0732-1331 is confirmed to be an intermediate polar.

710.225 | Efficient Simulations of Interstellar Gas-Grain Chemistry Using Moment
Equations | Networks of reactions on dust grain surfaces play a crucial role in the
chemistry of interstellar clouds, leading to the formation of molecular
hydrogen in diffuse clouds as well as various organic molecules in dense
molecular clouds. Due to the sub-micron size of the grains and the low flux,
the population of reactive species per grain may be very small and strongly
fluctuating. Under these conditions rate equations fail and the simulation of
surface-reaction networks requires stochastic methods such as the master
equation. However, the master equation becomes infeasible for complex networks
because the number of equations proliferates exponentially. Here we introduce a
method based on moment equations for the simulation of reaction networks on
small grains. The number of equations is reduced to just one equation per
reactive specie and one equation per reaction. Nevertheless, the method
provides accurate results, which are in excellent agreement with the master

710.2252 | The Spectrum of 1ES0229 + 200 and the Cosmic Infrared Background | We examine the effect of gamma-ray absorption by the extragalactic infrared
radiation on intrinsic spectra predicted for 1ES0229+200 and compare our
results with the observational data. We find agreement with our previous
results on the shape of the IR spectral energy distribution (SED), contrary to
the recent assertion of the HESS group. Our analysis indicates that 1ES0229+200
has a very hard intrinsic spectrum with a spectral index between 1.1 +/- 0.3
and 1.5 +/- 0.3 in the energy range between ~0.5 TeV and ~15 TeV. Under the
assumptions that (1) the SED models of Stecker, Malkan & Scully (2006) are
reasonable as derived from numerous detailed IR observations, and (2) spectral
indexes in the range 1 < \Gamma < 1.5 have been shown to be obtainable from
relativistic shock acceleration under the astrophysical conditions extant in
blazar flares (Stecker, Baring & Summerlin 2007), the fits to the observations
of 1ES0229+200 using our previous IR SEDs are consistent with both the IR and
gamma-ray observations. Our analysis presents evidence indicating that the
energy spectrum of relativistic particles in 1ES0229+200 is produced by
relativistic shock acceleration, producing an intrinsic gamma-ray spectrum with
index 1 < \Gamma < 1.5 and with no evidence of a peak in the SED up to energies
~15 TeV.
