712.0379 | The N=1 triplet vertex operator superalgebras | We introduce a new family of C_2-cofinite N=1 vertex operator superalgebras
SW(m), $m \geq 1$, which are natural super analogs of the triplet vertex
algebra family W(p), $p \geq 2$, important in logarithmic conformal field
theory. We classify irreducible SW(m)-modules and discuss logarithmic modules.
We also compute bosonic and fermionic formulas of irreducible SW(m) characters.
Finally, we contemplate possible connections between the category of
SW(m)-modules and the category of modules for the quantum group
U^{small}_q(sl_2), q=e^{\frac{2 \pi i}{2m+1}}, by focusing primarily on
properties of characters and the Zhu's algebra A(SW(m)). This paper is a
continuation of arXiv:0707.1857.

712.038 | Influence of a humidor on the aerodynamics of baseballs | We investigate whether storing baseballs in a controlled humidity environment
significantly affects their aerodynamic properties. To do this, we measure the
change in diameter and mass of baseballs as a function of relative humidity
(RH) in which the balls are stored. We then model trajectories for pitched and
batted baseballs to assess the difference between those stored at 30% RH versus
50% RH. The results show that a drier baseball may be expected to curve
slightly more than a humidified one for a given pitch velocity. We also find
that the aerodynamics alone would add ~2 feet to the distance a moister ball is
hit. However, this is compensated by a ~6 foot reduction in batted distance due
to the well known change in coefficient of restitution of the ball. We discuss
consequences of these results for baseball played at Coors Field in Denver,
where baseballs have been stored in a humidor at 50% RH since 2002.

712.0381 | Discovery of underground argon with low level of radioactive 39Ar and
possible applications to WIMP dark matter detectors | We report on the first measurement of 39Ar in argon from underground natural
gas reservoirs. The gas stored in the US National Helium Reserve was found to
contain a low level of 39Ar. The ratio of 39Ar to stable argon was found to be
<=4x10-17 (84% C.L.), less than 5% the value in atmospheric argon
(39Ar/Ar=8x10-16). The total quantity of argon currently stored in the National
Helium Reserve is estimated at 1000 tons. 39Ar represents one of the most
important backgrounds in argon detectors for WIMP dark matter searches. The

712.0383 | Interactions, star formation and AGN activity | It has long been known that galaxy interactions are associated with enhanced
star formation. In a companion paper, we explored this connection by applying a
variety of statistics to SDSS data. In particular, we showed that specific star
formation rates of galaxies are higher if they have close neighbours. Here we
apply exactly the same techniques to AGN in the survey, showing that close
neighbours are not associated with any similar enhancement of nuclear activity.
Star formation is enhanced in AGN with close neighbours in exactly the same way
as in inactive galaxies, but the accretion rate onto the black hole, as
estimated from the extinction-corrected [O III] luminosity, is not influenced
by the presence or absence of companions. Previous work has shown that galaxies
with more strongly accreting black holes contain more young stars in their
inner regions. This leads us to conclude that star formation induced by a close
companion and star formation associated with black hole accretion are distinct
events. These events may be part of the same physical process, for example a
merger, provided they are separated in time. In this case, accretion onto the
black hole and its associated star formation would occur only after the two
interacting galaxies have merged. The major caveat in this work is our
assumption that the extinction-corrected [O III] luminosity is a robust
indicator of the bolometric luminosity of the central black hole. It is thus
important to check our results using indicators of AGN activity at other
wavelengths.

712.0384 | Initial Data Release from the INT Photometric H-alpha Survey of the
Northern Galactic Plane (IPHAS) | The INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS)
is an imaging survey being carried out in H-alpha, r' and i' filters, with the
Wide Field Camera (WFC) on the 2.5-metre Isaac Newton Telescope (INT) to a
depth of r'=20 (10 sigma). The survey is aimed at revealing large scale
structure in our local galaxy, and also the properties of key early and late
populations making up the Milky Way. Mapping emission line objects enables a
particular focus on objects in the young and old stages of stellar evolution
ranging from early T-Tauri stars to late planetary nebulae. In this paper we
present the IPHAS Initial Data Release, primarily a photometric catalogue of
about 200 million unique objects, coupled with associated image data covering
about 1600 square degrees in three passbands. We note how access to the primary
data products has been implemented through use of standard virtual observatory
publishing interfaces. Simple traditional web access is provided to the main
IPHAS photometric catalogue, in addition to a number of common catalogues (such
as 2MASS) which are of immediate relevance. Access through the AstroGrid VO
Desktop opens up the full range of analysis options, and allows full
integration with the wider range of data and services available through the
Virtual Observatory. The IDR represents the largest dataset published primarily
through VO interfaces to date, and so stands as an examplar of the future of
survey data mining. Examples of data access are given, including a
cross-matching of IPHAS photometry with sources in the UKIDSS Galactic Plane
Survey that validates the existing calibration of the best data.

712.0385 | Induced gravity on intersecting brane-worlds Part I: Maximally symmetric
solutions | We explore models of intersecting brane-worlds with induced gravity terms on
codimension one branes and on their intersection. Maximally symmetric solutions
for the branes and the intersection are found. We find new self-accelerating
solutions. In a 6d spacetime, the solutions realize the see-saw modification of
gravity where the UV scale of the modification to 4d gravity is determined by
6d Planck scale given by $M_6 \sim 10^{-3}$eV and the IR scale of the
modification is determined by $M_6^2/M_4 \sim H_0 \sim 10^{-42}$ GeV where
$H_0$ is present-day Hubble scale. We find that it is increasingly difficult to
construct phenomenologically viable models in higher-dimensional spacetime due
to the necessity to have the lower value for the fundamental Planck scale to
realize the late time acceleration. It is found that the system also admits
self-tuning solutions where the tension at the intersection does not change the
geometry of the intersection. The induced gravity terms can avoid the necessity
to compactify the extra dimensions. Finally, we discuss the possibility to have
ordinary matter at the intersection, without introducing any regularisation,
using the induced gravity terms.

712.0386 | Jet signals for low mass strings at the LHC | The mass scale M_s of superstring theory is an arbitrary parameter that can
be as low as few TeVs if the Universe contains large extra dimensions. We
propose a search for the effects of Regge excitations of fundamental strings at
LHC, in the process p p \to \gamma jet. The underlying parton process is
dominantly the single photon production in gluon fusion, g g \to \gamma g, with
open string states propagating in intermediate channels. If the photon mixes
with the gauge boson of the baryon number, which is a common feature of D-brane
quivers, the amplitude appears already at the string disk level. It is
completely determined by the mixing parameter -- and it is otherwise
model-(compactification-) independent. Even for relatively small mixing, 100
fb^{-1} of LHC data could probe deviations from standard model physics, at a
5\sigma significance, for M_s as large as 3.3 TeV.

712.0387 | Signatures of Granulation in the Spectra of K-Dwarfs | Very high resolution (R>150,000) spectra of a small sample of nearby K-dwarfs
have been acquired to measure the line asymmetries and central wavelength
shifts caused by convective motions present in stellar photospheres. This
phenomenon of granulation is modeled by 3D hydrodynamical simulations but they
need to be confronted with accurate observations to test their realism before
they are used in stellar abundance studies. We find that the line profiles
computed with a 3D model agree reasonably well with the observations. The line
bisectors and central wavelength shifts on K-dwarf spectra have a maximum
amplitude of only about 200 m/s and we have been able to resolve these
granulation effects with a very careful observing strategy. By computing a
number of iron lines with 1D and 3D models (assuming local thermodynamic
equilibrium), we find that the impact of 3D-LTE effects on classical iron
abundance determinations is negligible.

712.0388 | From discs to planetesimals I: evolution of gas and dust discs | I review the processes that shape the evolution of protoplanetary discs
around young, solar-mass stars. I first discuss observations of protoplanetary
discs, and note in particular the constraints these observations place on
models of disc evolution. The processes that affect the evolution of gas discs
are then discussed, with the focus in particular on viscous accretion and
photoevaporation, and recent models which combine the two. I then discuss the
dynamics and growth of dust grains in discs, considering models of grain
growth, the gas-grain interaction and planetesimal formation, and review recent
research in this area. Lastly, I consider the so-called "transitional" discs,
which are thought to be observed during disc dispersal. Recent observations and

bulge fields of the MACHO Survey. These reddenings are determined using the
color at minimum $V$-band light of the RR0 Lyrae stars themselves and are found
to be in general agreement with extinction estimates at the same location
obtained from other methods. Using 3256 stars located in the Galactic Bulge, we
derive the selective extinction coefficient $R_{V,VR}=A_V/E(V-R) = 4.3 \pm

712.0391 | Modeling a simple enzyme reaction with delay and discretization | A comparison is made between conventional Michaelis-Menten kinetics and two
models that take into account the duration of the conformational changes that
take place at the molecular level during the catalytic cycle of a monomer. The
models consider the time that elapses from the moment an enzyme-substrate
complex forms until the moment a product molecule is released, as well as the
recovery time needed to reset the conformational change that took place. In the
first model the dynamics is described by a set of delayed differential
equations, instead of the ordinary differential equations associated to
Michaelis-Menten kinetics. In the second model the delay, the discretization
inherent to enzyme reactions and the stochastic binding of substrates to
enzimes at the molecular level is considered. All three models agree at
equilibrium, as expected; however, out-of-equilibrium dynamics can differ
substantially. In particular, both delayed models show oscillations at low
values of the Michaelis constant which are not reproduced by the
Michaelis-Menten model. Additionally, in certain cases, the dynamics shown by
the continuous delayed model differs from the dynamics of the discrete delayed
model when some reactant become scarce.
| q-bio.MN q-bio.QM | a comparison is made between conventional michaelismenten kinetics and two models that take into account the duration of the conformational changes that take place at the molecular level during the catalytic cycle of a monomer the models consider the time that elapses from the moment an enzymesubstrate complex forms until the moment a product molecule is released as well as the recovery time needed to reset the conformational change that took place in the first model the dynamics is described by a set of delayed differential equations instead of the ordinary differential equations associated to michaelismenten kinetics in the second model the delay the discretization inherent to enzyme reactions and the stochastic binding of substrates to enzimes at the

712.0395 | Rips Complexes of Planar Point Sets | Fix a finite set of points in Euclidean $n$-space $\euc^n$, thought of as a
point-cloud sampling of a certain domain $D\subset\euc^n$. The Rips complex is
a combinatorial simplicial complex based on proximity of neighbors that serves
as an easily-computed but high-dimensional approximation to the homotopy type
of $D$. There is a natural ``shadow'' projection map from the Rips complex to
$\euc^n$ that has as its image a more accurate $n$-dimensional approximation to
the homotopy type of $D$.
We demonstrate that this projection map is 1-connected for the planar case
$n=2$. That is, for planar domains, the Rips complex accurately captures
connectivity and fundamental group data. This implies that the fundamental
group of a Rips complex for a planar point set is a free group. We show that,
in contrast, introducing even a small amount of uncertainty in proximity
detection leads to `quasi'-Rips complexes with nearly arbitrary fundamental
groups. This topological noise can be mitigated by examining a pair of
quasi-Rips complexes and using ideas from persistent topology. Finally, we show
that the projection map does not preserve higher-order topological data for
planar sets, nor does it preserve fundamental group data for point sets in
dimension larger than three.

712.0396 | Electroweak Corrections in High Energy Processes using Effective Field
Theory | Electroweak Sudakov logarithms at high energy, of the form
alpha/(sin^2theta_W)^n log^m s/M_{Z,W}^2, are summed using effective theory
methods. The corrections are computed to processes involving two external
particles in the standard model. The results include non-zero particle masses,
such as the t-quark mass, electroweak mixing effects which lead to unequal W
and Z masses, and radiative Higgs corrections proportional to the Yukawa
couplings. We show that the matching at the scale M_{W,Z} has a term at most

712.0397 | Kinetic models of heterogeneous dissipation | We suggest kinetic models of dissipation for an ensemble of interacting
oriented particles, for example, moving magnetized particles. This is achieved
by introducing a double bracket dissipation in kinetic equations using an
oriented Poisson bracket, and employing the moment method to derive continuum
equations for magnetization and density evolution. We show how our continuum
equations generalize the Debye-Hueckel equations for attracting round
particles, and Landau-Lifshitz-Gilbert equations for spin waves in magnetized
media. We also show formation of singular solutions that are clumps of aligned
particles (orientons) starting from random initial conditions. Finally, we
extend our theory to the dissipative motion of self-interacting curves.

712.0398 | Cosmic Variance and Its Effect on the Luminosity Function Determination
in Deep High z Surveys | We study cosmic variance in deep high redshift surveys and its influence on
the determination of the luminosity function for high redshift galaxies. For
several survey geometries relevant for HST and JWST instruments, we
characterize the distribution of the galaxy number counts. This is obtained by
means of analytic estimates via the two point correlation function in extended
Press-Schechter theory as well as by using synthetic catalogs extracted from
N-body cosmological simulations of structure formation. We adopt a simple
luminosity - dark halo mass relation to investigate the environment effects on
the fitting of the luminosity function. We show that in addition to variations
of the normalization of the luminosity function, a steepening of its slope is
also expected in underdense fields, similarly to what is observed within voids
in the local universe. Therefore, to avoid introducing artificial biases,
caution must be taken when attempting to correct for field underdensity, such
as in the case of HST UDF i-dropout sample, which exhibits a deficit of bright
counts with respect to the average counts in GOODS. A public version of the
cosmic variance calculator based on the two point correlation function
integration is made available on the web.

712.0399 | Shear-transformation-zone theory of plastic deformation near the glass
transition | The shear-transformation-zone (STZ) theory of plastic deformation in
glass-forming materials is reformulated in light of recent progress in
understanding the roles played the effective disorder temperature and entropy
flow in nonequilibrium situations. A distinction between fast and slow internal
state variables reduces the theory to just two coupled equations of motion, one
describing the plastic response to applied stresses, and the other the dynamics
of the effective temperature. The analysis leading to these equations contains,
as a byproduct, a fundamental reinterpretation of the dynamic yield stress in
amorphous materials. In order to put all these concepts together in a realistic
context, the paper concludes with a reexamination of the experimentally
observed rheological behavior of a bulk metallic glass. That reexamination
serves as a test of the STZ dynamics, confirming that system parameters
obtained from steady-state properties such as the viscosity can be used to
predict transient behaviors.

712.04 | Phase Variation of Hadronic Amplitudes | The phase variation with angle of hadronic amplitudes is studied with a view
to understanding the underlying physical quantities which control it and how
well it can be determined in free space. We find that unitarity forces a
moderately accurate determination of the phase in standard amplitude analyses
but that the nucleon-nucleon analyses done to date do not give the phase
variation needed to achieve a good representation of the data in multiple
scattering calculations. Models are examined which suggest its behavior near
forward angles is related to the radii of the real and absorptive parts of the
interaction. The dependence of this phase on model parameters is such that if
these radii are modified in the nuclear medium (in combination with the change
due to the shift in energy of the effective amplitude in the medium) then the
larger magnitudes of the phase needed to fit the data might be attainable, but
only for negative values of the phase variation parameter.

how the properties of such an extension are weakened and/or modified as
compared to AdS spacetime, and probing how non-trivial gravitational effects
manifest themselves in the conformal infinity's quantum theory. The language

712.0402 | On Naturalness of Scalar Fields and Standard Model | We discuss how naturalness predicts the scale of new physics. Two conditions
on the scale are considered. The first is the more conservative condition due
to Veltman (Acta Phys. Polon. B 12, 437 (1981)). It requires that radiative
corrections to the electroweak mass scale would be reasonably small. The second
is the condition due to Barbieri and Giudice (Nucl. Phys. B 306, 63 (1988)),
which is more popular lately. It requires that physical mass scale would not be
oversensitive to the values of the input parameters. We show here that the
above two conditions behave differently if higher order corrections are taken
into account. Veltman's condition is robust (insensitive to higher order
corrections), while Barbieri-Giudice condition changes qualitatively. We
conclude that higher order perturbative corrections take care of the fine
tuning problem, and, in this respect, scalar field is a natural system. We
apply the Barbieri-Giudice condition with higher order corrections taken into
account to the Standard Model, and obtain new restrictions on the Higgs boson
mass.

712.0403 | Entropy localization and extensivity in the semiclassical black hole
evaporation | We aim to quantify the distribution of information in the Hawking radiation
and inside the black hole in the semiclassical evaporation process. The
structure quantum field theory forces to consider a shared information between
two different regions of space-time. Using this tool, we show that the entropy
of a thermal gas at the Unruh temperature underestimates the actual amount of
(shared) information present in a region of the Rindler space. Then, we analyze
the mutual information between the black hole and the late time radiation
region. We show that in the semiclassical picture it is not possible to recover
the eventual purity of the initial state in the final Hawking radiation through
correlations established during the whole evaporation period, no matter the
interactions present in the theory. We find extensivity of the entropy as a
consequence of a reduction to a two dimensional conformal problem in a simple
approximation. However, this seems not to be guaranteed in a full four
dimensional calculation. We also find that a large amount of information is
contained in a small approximately flat region of space-time near the point
where the horizon begins. This gives place to large violations of the entropy
bounds. This problem is not eased by backscattering effects and we argue that a
breaking of conformal invariance is necessary to delocalize the entropy.
Finally, we indicate that the mutual information could lead to a way to
understand the Bekenstein-Hawking black hole entropy which does not require a
reduction in degrees of freedom in order to regulate the entanglement entropy.
On the contrary a large number of field degrees of freedom at high energies
giving place to a Hagedorn transition implements a distance cutoff in the
mutual information, which may in consequence turn out to be bounded.

712.0404 | Finite size effects on spin-torque driven ferromagnetic resonance in
spin-valves with a Co/Ni synthetic free layer | Spin-torque driven ferromagnetic resonance (ST-FMR) is used to study magnetic
excitations in Co/Ni synthetic layers confined in nanojunctions. Field swept
ST-FMR measurements were conducted with a magnetic field applied perpendicular
to the layer surface. The resonance lines were measured under low amplitude
excitation in a linear response regime. The resulting resonance fields were
compared with those obtained using conventional rf field driven FMR on extended
films with the same Co/Ni layer structure. A lower resonance field is found in
confined structures. The effect of both dipolar fields acting on the Co/Ni
layer emanating from other magnetic layers in the device and finite size
effects on the spin wave spectrum are discussed.

712.0406 | Model-Independent Bottom Baryon Mass Predictions in the 1/N Expansion | Recent discoveries of the Xi_b, Sigma_b and Sigma_b^* baryons at the Tevatron
are in good agreement with model-independent mass predictions made a decade ago
based on a combined expansion in 1/N_c, 1/m_Q and SU(3) flavor symmetry
breaking. Using the new experimental data as input, mass predictions for the
undiscovered bottom baryons Xi_b^\prime, Xi_b^*, Omega_b and Omega_b^* and for
many unmeasured bottom baryon mass splittings are updated. The observed ground

712.0408 | Inverse Problems for Representation Functions in Additive Number Theory | For every positive integer h, the representation function of order h
associated to a subset A of the integers or, more generally, of any group or
semigroup X, counts the number of ways an element of X can be written as the
sum (or product, if X is nonabelian) of h not necessarily distinct elements of
X. The direct problem for representation functions in additive number theory
begins with a subset A of X and seeks to understand its representation
functions. The inverse problem for representation functions starts with a
function f:X ->N_0 U {\infty} and asks if there is a set A whose representation
function is f, and, if the answer is yes, to classify all such sets. This paper
is a survey of recent progress on the inverse representation problem.

712.0412 | Biases for neutron-star mass, radius and distance measurements from
Eddington-limited X-ray bursts | Eddington-limited X-ray bursts from neutron stars can be used in conjunction
with other spectroscopic observations to measure neutron star masses, radii,
and distances. In order to quantify some of the uncertainties in the
determination of the Eddington limit, we analysed a large sample of
photospheric radius-expansion thermonuclear bursts observed with the Rossi
X-ray Timing Explorer. We identified the instant at which the expanded
photosphere "touches down" back onto the surface of the neutron star and
compared the corresponding touchdown flux to the peak flux of each burst. We
found that for the majority of sources, the ratio of these fluxes is smaller
than 1.6, which is the maximum value expected from the changing gravitational
redshift during the radius expansion episodes (for a 2M_sun neutron star). The
only sources for which this ratio is larger than 1.6 are high inclination
sources that include dippers and Cyg X-2. We discuss two possible geometric
interpretations of this effect and show that the inferred masses and radii of
neutron stars are not affected by this bias. On the other hand, systematic
uncertainties as large as ~50% may be introduced to the distance determination.

Observations | We study finite horizon optimal switching problems for hidden Markov chain
models under partially observable Poisson processes. The controller possesses a
finite range of strategies and attempts to track the state of the unobserved
state variable using Bayesian updates over the discrete observations. Such a
model has applications in economic policy making, staffing under variable
demand levels and generalized Poisson disorder problems. We show regularity of
the value function and explicitly characterize an optimal strategy. We also
provide an efficient numerical scheme and illustrate our results with several

712.0414 | Instanton Calculus and Loop Operator in Supersymmetric Gauge Theory | We compute one-point function of the glueball loop operator in the maximally
confining phase of supersymmetric gauge theory using instanton calculus. In the
maximally confining phase the residual symmetry is the diagonal U(1) subgroup
and the localization formula implies that the chiral correlation functions are
the sum of the contributions from each fixed point labeled by the Young
diagram. The summation can be performed exactly by operator formalism of free
fermions, which also featured in the equivariant Gromov-Witten theory of P^1.
By taking the Laplace transformation of the glueball loop operator, we find an
exact agreement with the previous results for the generating function
(resolvent) of the glueball one-point functions.

712.0415 | Random and Longest Paths: Unnoticed Motifs of Complex Networks | Paths are important structural elements in complex networks because they are
finite (unlike walks), related to effective node coverage (minimum spanning
trees), and can be understood as being dual to star connectivity. This article
introduces the concept of random path applies it for the investigation of
structural properties of complex networks and as the means to estimate the
longest path. Random paths are obtained by selecting one of the network nodes
at random and performing a random self-avoiding walk (here called path-walk)
until its termination. It is shown that the distribution of random paths are
markedly different for diverse complex network models (i.e. Erdos-Renyi,
Barabasi-Albert, Watts-Strogatz, a geographical model, as well as two recently
introduced path-based network types), with the BA structures yielding the
shortest random walks, while the longest paths are produced by WS networks.
Random paths are also explored as the means to estimate the longest paths (i.e.
several random paths are obtained and the longest taken). The convergence to
the longest path and its properties ire characterized with respect to several
networks models. Several results are reported and discussed, including the
markedly distinct lengths of the longest paths obtained for the different
network models.

712.0416 | Galaxy Mergers at z>1 in the HUDF: Evidence for a Peak in the Major
Merger Rate of Massive Galaxies | We present a measurement of the galaxy merger fraction and number density
from observations in the Hubble Ultra Deep Field for 0.5<z<2.5. We fit the
combination of broadband data and slitless spectroscopy of 1308 galaxies with
stellar population synthesis models to select merging systems based on a
stellar mass of >10^10 M_sol. When correcting for mass incompleteness, the
major merger fraction is not simply proportional to (1+z)^m, but appears to
peak at z_frac~=1.3+-0.4. From this merger fraction, we infer that ~42% of
massive galaxies have undergone a major merger since z~1. We show that the
major merger number density peaks at z_dens~1.2, which marks the epoch where
major merging of massive galaxies is most prevalent. This critical redshift is
comparable to the peak of the cosmic star formation rate density, and occurs
roughly 2.6 Gyr earlier in cosmic time than the peak in the number density of
X-ray selected active galactic nuclei. These observations support an indirect
evolutionary link between merging, starburst, and active galaxies.

712.0419 | Pressure dependence of the superconducting transition and electron
correlations in Na_xCoO_2 \cdot 1.3H_2O | We report T_c and ^{59}Co nuclear quadrupole resonance (NQR) measurements on
the cobalt oxide superconductor Na_{x}CoO_{2}\cdot 1.3H_{2}O (T_c=4.8 K) under
hydrostatic pressure (P) up to 2.36 GPa. T_c decreases with increasing pressure
at an average rate of -0.49\pm0.09 K/GPa. At low pressures P\leq0.49 GPa, the
decrease of T_c is accompanied by a weakening of the spin correlations at a
finite wave vector and a reduction of the density of states (DOS) at the Fermi
level. At high pressures above 1.93 GPa, however, the decrease of T_c is mainly
due to a reduction of the DOS. These results indicate that the
electronic/magnetic state of Co is primarily responsible for the
superconductivity. The spin-lattice relaxation rate 1/T_1 at P=0.49 GPa shows a
T^3 variation below T_c down to T\sim 0.12T_c, which provides compelling
evidence for the presence of line nodes in the superconducting gap function.

convex-shaped particles (p > 0.5, with the circular-disk case p = 1) and
concave-shaped particles (0 < p < 0.5). The packings of the convex cases with p
1 generated by a recently developed event-driven molecular dynamics (MD)
simulation algorithm [Donev, Torquato and Stillinger, J. Comput. Phys. 202
(2005) 737] suggest exact constructions of the densest known packings. We find
that the packing density (covering fraction of the particles) increases
dramatically as the particle shape moves away from the "circular-disk" point (p
= 1). In particular, we find that the maximal packing densities of superdisks
for certain p 6 = 1 are achieved by one of the two families of Bravais lattice
packings, which provides additional numerical evidence for Minkowski's
conjecture concerning the critical determinant of the region occupied by a
superdisk. Moreover, our analysis on the generated packings reveals that the
broken rotational symmetry of superdisks influences the packing characteristics
in a non-trivial way. We also propose an analytical method to construct dense
packings of concave superdisks based on our observations of the structural
properties of packings of convex superdisks.

712.0421 | Novel Orientational Ordering and Reentrant Metallicity in KxC60
Monolayers for 3 <= x <= 5 | We have performed local STM studies on potassium-doped C60 (KxC60) monolayers
over a wide regime of the phase diagram. As K content increases from x = 3 to
5, KxC60 monolayers undergo metal-insulator-metal reentrant phase transitions
and exhibit a variety of novel orientational orderings. The most striking new
structure has a pinwheel-like 7-molecule unit cell in insulating K4+dC60. We
propose that the driving mechanism for the orientational ordering in KxC60 is
the lowering of electron kinetic energy through maximization of the overlap of
neighboring molecular orbitals over the entire doping range x = 3 to 5. In the
insulating and metallic phases this gives rise to orbital versions of the
superexchange and double-exchange interactions respectively.

712.0422 | Tuning fulleride electronic structure and molecular ordering via
variable layer index | C60 fullerides are uniquely flexible molecular materials that exhibit a rich
variety of behavior, including superconductivity and magnetism in bulk
compounds, novel electronic and orientational phases in thin films, and quantum
transport in a single-C60 transistor. The complexity of fulleride properties
stems from the existence of many competing interactions, such as
electron-electron correlations, electron-vibration coupling, and intermolecular
hopping. The exact role of each interaction is controversial due to the
difficulty of experimentally isolating the effects of a single interaction in
the intricate fulleride materials. Here we report a unique level of control of
the material properties of KxC60 ultra-thin films through well-controlled
atomic layer indexing and accurate doping concentrations. Using STM techniques,
we observe a series of electronic and structural phase transitions as the
fullerides evolve from two-dimensional monolayers to quasi-threedimensional
multilayers in the early stages of layer-by-layer growth. These results
demonstrate the systematic evolution of fulleride electronic structure and
molecular ordering with variable KxC60 film layer index, and shed new light on
creating novel molecular structures and devices.

712.0423 | Hyperaccretion Disks around Neutron Stars | (Abridged) We here study the structure of a hyperaccretion disk around a
neutron star. We consider a steady-state hyperaccretion disk around a neutron
star, and as a reasonable approximation, divide the disk into two regions,
which are called inner and outer disks. The outer disk is similar to that of a
black hole and the inner disk has a self-similar structure. In order to study
physical properties of the entire disk clearly, we first adopt a simple model,
in which some microphysical processes in the disk are simplified, following
Popham et al. and Narayan et al. Based on these simplifications, we
analytically and numerically investigate the size of the inner disk, the
efficiency of neutrino cooling, and the radial distributions of the disk
density, temperature and pressure. We see that, compared with the black-hole
disk, the neutron star disk can cool more efficiently and produce a much higher
neutrino luminosity. Finally, we consider an elaborate model with more physical
considerations about the thermodynamics and microphysics in the neutron star
disk (as recently developed in studying the neutrino-cooled disk of a black
hole), and compare this elaborate model with our simple model. We find that
most of the results from these two models are basically consistent with each
other.

712.0424 | First-Principles Semiclassical Initial Value Representation Molecular
Dynamics | A method for carrying out semiclassical initial value representation
calculations using first-principles molecular dynamics (FP-SC-IVR) is
presented. This method can extract the full vibrational power spectrum of
carbon dioxide from a single trajectory providing numerical results that agree
with experiment even for Fermi resonant states. The computational demands of
the method are comparable to those of classical single-trajectory calculations,
while describing uniquely quantum features such as the zero-point energy and
Fermi resonances. By propagating the nuclear degrees of freedom using
first-principles Born-Oppenheimer molecular dynamics, the stability of the
method presented is improved considerably when compared to dynamics carried out
using fitted potential energy surfaces and numerical derivatives.

712.0425 | The number of hypergraphs and colored Hypergraphs with hereditary
properties | As an application of Szemeredi's regularity lemma, Erdos-Frankl-Rodl (1986)
showed that the number of graphs on vertex set {1,2,...n} with a monotone class
P is $2^{(1+o(1))ex(n,P)n^2/2}$ where $ex(n,P)$ is the maximum number of edges
of an n-vertex graph which has no subgraph in P. Kohayakawa et al. (2003)
extended it from monotone to hereditary and from graphs to 3-uniform

712.0427 | Analogue spacetimes: Toy models for "quantum gravity'' | Why are "analogue spacetimes'' interesting? For the purposes of this workshop
the answer is simple: Analogue spacetimes provide one with physically
well-defined and physically well-understood concrete models of many of the
phenomena that seem to be part of the yet incomplete theory of "quantum
gravity'', or more accessibly, "quantum gravity phenomenology''. Indeed
"analogue spacetimes'' provide one with concrete models of "emergence''
(whereby the effective low-energy theory can be radically different from the
high-energy microphysics). They also provide many concrete and controlled
models of "Lorentz symmetry breaking'', and extensions of the usual notions of
pseudo-Riemannian geometry such as "rainbow spacetimes'', and pseudo-Finsler
geometries, and more. I will provide an overview of the key items of "unusual
physics'' that arise in analogue spacetimes, and argue that they provide us
with hints of what we should be looking for in any putative theory of "quantum
gravity''. For example: The dispersion relations that naturally arise in the
known emergent/analogue spacetimes typically violate analogue Lorentz
invariance at high energy, but do not do so in completely arbitrary manner.
This suggests that a search for arbitrary violations of Lorentz invariance is
possibly overkill: There are a number of natural and physically well-motivated
restrictions one can put on emergent/ analogue dispersion relations,
considerably reducing the plausible parameter space.

712.0428 | Experimentally accessible reentrant phase transitions in double-well
optical lattices | We study the quantum phases of bosons confined in a combined potential of a
one-dimensional double-well optical lattice and a parabolic trap. We apply the
time-evolving block decimation method to the corresponding two-legged
Bose-Hubbard model. In the absence of a parabolic trap, the system of bosons in
the double-well optical lattice exhibits a reentrant quantum phase transition
between Mott insulator and superfluid phases at unit filling as the tilt of the
double-wells is increased. We show that the reentrant phase transition occurs
also in the presence of a parabolic trap and suggest that it can be detected in
experiments by measuring the matter-wave interference pattern.

$g_{HH\rho}$, $f_{H^*H\rho}$, $g_{H^*H^*\rho}$ and $f_{H^*H^*\rho}$ enter the
effective lagrangian, where $H$ $(H^*)$ denotes a pseudoscalar bottom or charm

method and, as inputs, the hadronic parameters updated recently, we give an
estimate of $g_{H^*H^*\rho}$ and $f_{H^*H^*\rho}$, about which little was known
before, and present an improved result for $g_{HH\rho}$ and $f_{H^*H\rho}$.
Also, we examine the heavy quark asymptotic behavior of these nonperturbative
quantities and assess the two low energy parameters $\beta$ and $\lambda$ of
the corresponding effective chiral lagrangian.

712.043 | Long Gamma-Ray Bursts and Type Ic Core Collapse Supernovae Have Similar
Locations in Hosts | When the afterglow fades at the site of a long-duration gamma-ray burst
(LGRB), Type Ic supernovae (SN Ic) are the only type of core collapse supernova
observed. Recent work found that a sample of LGRB in high-redshift galaxies had
different environments from a collection of core-collapse environments, which
were identified from their colors and light curves. LGRB were in the brightest
regions of their hosts, but the core-collapse sample followed the overall
distribution of the galaxy light. Here we examine 504 supernovae with types
assigned based on their spectra that are located in nearby (z < 0.06) galaxies
for which we have constructed surface photometry from the Sloan Digital Sky
Survey (SDSS). The distributions of the thermonuclear supernovae (SN Ia) and
some varieties of core-collapse supernovae (SN II and SN Ib) follow the galaxy
light, but the SN Ic (like LGRB) are much more likely to erupt in the brightest
regions of their hosts. The high-redshift hosts of LGRB are overwhelmingly
irregulars, without bulges, while many low redshift SN Ic hosts are spirals
with small bulges. When we remove the bulge light from our low-redshift sample,
the SN Ic and LGRB distributions agree extremely well. If both LGRB and SN Ic
stem from very massive stars, then it seems plausible that the conditions
necessary for forming SN Ic are also required for LGRB. Additional factors,
including metallicity, may determine whether the stellar evolution of a massive
star leads to a LGRB with an underlying broad-lined SN Ic, or simply a SN Ic
without a gamma-ray burst.

kinetics by means of the non-adiabatic geometrical phase interpretation. The
two-state system is attached to two particle reservoirs, and under a periodic
perturbation of the kinetic rates, it gives rise to a pump current between the
two-state system and the absorbing states. In order to calculate the pump
current, the Floquet theory for the non-adiabatic geometrical phase is extended
from a Hermitian case to a non-Hermitian case. The dependence of the pump
current on the frequency of the perturbative kinetic rates is explicitly
derived, and a stochastic resonance-like behavior is obtained.

712.0434 | The phase diagram of QCD at small chemical potentials | We investigate the phase diagram of QCD at small chemical potentials, ie,
when chiral and flavour symmetry breaking involves the pairing of a quark and
an antiquark. The phase diagram of two-flavour QCD at small chemical potentials
involves chiral symmetry restoration and charged pion condensation. We extend
previous studies of the topology of the phase diagram, in sections with high
degree of symmetry, to the physical case of fully broken flavour symmetry,
using generic thermodynamic arguments. We argue that the extension is unique
and present the result. In three flavour QCD the phase diagram for chiral
symmetry restoration is less well constrained. However, we argue that present
lattice data allows just two different phase diagrams, which we discuss.

712.0435 | A Global Probe of Cosmic Magnetic Fields to High Redshifts | Faraday rotation (RM) probes of magnetic fields in the universe are sensitive
to cosmological and evolutionary effects as $z$ increases beyond $\sim $1
because of the scalings of electron density and magnetic fields, and the growth
in the number of expected intersections with galaxy-scale intervenors,
$d$N/$dz$. In this new global analysis of an unprecedented large sample of RM's
of high latitude quasars extending out to $z\sim $3.7 we find that the
distribution of RM broadens with redshift in the 20 $-$ 80 rad m$^{-2}$ range
range, despite the (1 +$z$)$^{-2}$ wavelength dilution expected in the observed
Faraday rotation. Our results indicate that the Universe becomes increasingly
``Faraday-opaque'' to sources beyond $z \sim$ 2, that is, as $z$ increases
progressively fewer sources are found with a ``small'' RM in the observer's
frame. This is in contrast to sources at $z \la$1. They suggest that the
environments of galaxies were significantly magnetized at high redshifts, with
magnetic field strengths that were at least as strong within a few Gyr of the
Big Bang as at the current epoch. We separately investigate a simple unevolving
toy model in which the RM is produced by MgII absorber systems, and find that
it can approximately reproduce the observed trend with redshift. An additional
possibility is that the intrinsic RM associated with the radio sources was much
higher in the past, and we show that this is not a trivial consequence of the
higher radio luminosities of the high redshift sources.

712.0436 | Resonant carrier dynamics in strongly biassed superlattices | We study coherent electron dynamics in a biassed undriven ideal semiconductor
superlattice coupled to the continuum, near energy level anticrossings. In
particular, we examine the dependence of wavepacket dynamical characteristics
on electric field detuning, and investigate mixed regimes involving a
superposition of energy level anticrossings showing both Rabi oscillations and
resonant tunnelling. In earlier work [Phys. Rev. B 75 165421 (2007)], Rabi and
Zener resonances were shown to have a common origin, and a criteria for the
occurrence of either was proposed. The present results allow a better
understanding of the nature of an interminiband resonance, which can be useful
in the areas of microwave radiation generation and matter manipulation on the
particle level, as well as demonstrate an alternative approach to examining
electron level structure of a finite superlattice.

712.0437 | Quantum phases and transitions of excitons, metastable excitonic
supersolid and its internal photon detection in electron-hole bilayer systems | We construct a quantum Ginsburg-Landau theory to study the quantum phases and
transitions in electron hole bilayer system. We propose that in the dilute
limit as distance is increased, there is a first order transition from the
excitonic superfluid (ESF) to the excitonic supersolid (ESS) driven by the
collapsing of a roton minimum, then a 2nd order transition from the ESS to
excitonic normal solid. We show the latter transition is in the same
universality class of superfluid to Mott transition in a rigid lattice. We then
study novel elementary low energy excitations inside the ESS. We find that
there are two "supersolidon" longitudinal modes (one upper branch and one lower
branch) inside the ESS, while the transverse mode in the ESS stays the same as
that inside a ENS. We also work out various experimental signatures of these
novel elementary excitations by evaluating the Debye-Waller factor,
density-density correlation, specific heat and vortex -vertex interactions. For
the meta-stable supersolid generated by photon pumping, we show that the angle
resolved spectrum is dominated by the macroscopic super-radiance from its
superfluid component, even it is just a very small percentage of the the whole
system. This fact can be used to detect the metastable ESS state generated by
photon pumping by a power spectrum experiment easily and without any ambiguity.

712.0438 | Solvable automorphism groups of a compact Kaehler manifold | Let X be a compact Kaehler manifold of complex dimension n. Let G be a
connected solvable subgroup of the automorphism group Aut(X), and let N(G) be
the normal subgroup of G of elements of null entropy. One of the goals of this
paper is to show that G/N(G) is a free abelian group of rank r(G) less than or
equal to n-1 and that the rank estimate is optimal. This gives an alternative
proof of the conjecture of Tits type. In addition, we show some non-obvious
implications on the structure of solvable automorphism groups of compact
Kaehler manifolds. Furthermore, we also show that if the rank r(G) of the
quotient group G/N(G) is equal to n-1 and the identity component Aut_0(X) of
Aut(X) is trivial, then N(G) is a finite set. The main strategy of this paper
is to combine the method of Dinh and Sibony and the theorem of

712.0439 | The mesoscopic conductance of disordered rings, its random matrix
theory, and the generalized variable range hopping picture | The calculation of the conductance of disordered rings requires a theory that
goes beyond the Kubo-Drude formulation. Assuming "mesoscopic" circumstances the
analysis of the electro-driven transitions show similarities with a percolation
problem in energy space. We argue that the texture and the sparsity of the
perturbation matrix dictate the value of the conductance, and study its
dependence on the disorder strength, ranging from the ballistic to the Anderson
localization regime. An improved sparse random matrix model is introduced to
captures the essential ingredients of the problem, and leads to a generalized
variable range hopping picture.

712.0442 | Spin orientation and spin-Hall effect induced by tunneling electrons | It is shown that a flux of unpolarized electrons across a symmetric double
barrier quantum well induces a spin polarization inside the well. Besides, the
transmitted current acquires a spin polarized component and the spin-Hall
current flows in the planar direction. These phenomena are due to a combined
effect of Dresselhaus interaction and the spin-orbit interaction induced by
gradients of heterostructure material parameters. In contrast to previous
studies of the spin filtering effect, we predict that it can be observed in

712.0443 | Quantum transport in a normal metal/odd-frequency superconductor
junction | Recent experimental results indicate the possible realization of a bulk
odd-frequency superconducting state in the compounds CeCu$_2$Si$_2$, and
CeRhIn$_5$. Motivated by this, we present a study of the quantum transport
properties of a normal metal/odd-frequency superconductor junctions in a search
for probes to unveil the odd-frequency symmetry. From the Eliashberg equations,
we perform a quasiclassical approximation to account for the transport
formalism of an odd-frequency superconductor with the Keldysh formalism.
Specifically, we consider the tunneling charge conductance and tunneling
thermal conductance. We find qualitatively distinct behaviour in the
odd-frequency case as compared to the conventional even-frequency case, in both
the electrical and thermal current. This serves as a useful tool to identify
the possible existence of a bulk odd-frequency superconducting state.

712.0445 | On the renormalization group flow of f(R)-gravity | We use the functional renormalization group equation for quantum gravity to
construct a non-perturbative flow equation for modified gravity theories of the
form $S = \int d^dx \sqrt{g} f(R)$. Based on this equation we show that certain
gravitational interactions monomials can be consistently decoupled from the
renormalization group (RG) flow and reproduce recent results on the asymptotic
safety conjecture. The non-perturbative RG flow of non-local extensions of the
Einstein-Hilbert truncation including $\int d^dx \sqrt{g} \ln(R)$ and $\int
d^dx \sqrt{g} R^{-n}$ interactions is investigated in detail. The inclusion of
such interactions resolves the infrared singularities plaguing the RG
trajectories with positive cosmological constant in previous truncations. In
particular, in some $R^{-n}$-truncations all physical trajectories emanate from
a Non-Gaussian (UV) fixed point and are well-defined on all RG scales. The RG
flow of the $\ln(R)$-truncation contains an infrared attractor which drives a
positive cosmological constant to zero dynamically.

712.0446 | Tidal Evolution of Rubble Piles | Many small bodies in the solar system are believed to be rubble piles, a
collection of smaller elements separated by voids. We propose a model for the
structure of a self-gravitating rubble pile. Static friction prevents its
elements from sliding relative to each other. Stresses are concentrated around
points of contact between individual elements. The effective dimensionless
rigidity, $\tilde\mu_{rubble}$, is related to that of a monolithic body of
similar composition and size, $\tilde\mu$ by $\tilde \mu_{rubble} \sim \tilde
\mu^{1/2} \epsilon_Y^{-1/2}$, where $\epsilon_Y \sim 10^{-2}$ is the yield
strain. This represents a reduction in effective rigidity below the maximum
radius, $R_{max}\sim [\mu\epsilon_Y/(G\rho^2)]^{1/2}\sim 10^3\km$, at which a
rubble pile can exist. Densities derived for binary near-Earth asteroids imply
that they are rubble piles. As a consequence, their tidal evolution proceeds
$10^3$ to $10^4$ times faster than it would if they were monoliths. This
accounts for both the sizes of their semimajor axes and their small orbital

712.0447 | The stars and gas in outer parts of galaxy disks: Extended or truncated
-- flat or warped? | I review observations of truncations of stellar disks and models for their
origin, compare observations of truncations in moderately inclined galaxies to
those in edge-on systems and discuss the relation between truncations and
HI-warps and their systematics and origin. Truncations are a common feature in
edge-on stellar disks, but the relation of truncations in face-on to those in
edge-on galaxies needs further clarification. The origin of truncations is most
likely related to a maximum in the specific angular momentum in the material
that formed the stellar disks, but this model does probably require some
redistribution of angular momentum. HI-warps start just beyond the truncation
radius and disks and warps appear distinct components. This suggests that inner
disks form initially and settle as rigid, very flat structures, while HI-warps
result from later infall of gas with a different orientation of the angular
momentum.

712.0448 | The Private Higgs | We introduce Higgs democracy in the Yukawa sector by constructing a model
with a private Higgs and a dark scalar for each fermion thus addressing the
large hierarchy among fermion masses. The model has interesting implications
for the LHC, while the Standard Model phenomenology is recovered at low

712.0449 | Metal - Insulator Transition in 3D Quantum Percolation | We present the metal - insulator transition study of a quantum site
percolation model on simple cubic lattice. Transfer matrix method is used to
calculate transport properties - Landauer conductance - for the binary
distribution of energies. We calculate the mobility edge in disorder (ratio of
insulating sites) - energy plane in detail and we find the extremal critical
disorder somewhat closer to the classical percolation threshold, than formerly
reported. We calculate the critical exponent $\nu$ along the mobility edge and
find it constant and equal to the one of 3D Anderson model, confirming common
universality class. Possible exception is the center of the conduction band,
where either the single parameter scaling is not valid anymore, or finite size
effects are immense. One of the reasons for such statement is the difference
between results from arithmetic and geometric averaging of conductance at
special energies. Only the geometric mean yields zero critical disorder in band
center, which was theoretically predicted.

712.045 | Several Action and Action Deformation Proposals in f(R) Variable G
Modified Gravities and a Brief Expose on Variable G Ontology | This note includes five sections. In section 2 a number of aesthetically
motivated f(R) Lagrangians is proposed and frivolously explored in the metric
formalism with variable Newton constant G(x). In section 3 the idea of
deforming the terms in a given f(R) gravity-matter action S, and prior to
extremizing it, is promoted with the aim of reducing S via an algebraic mixing
between few selected gravity and matter terms without invoking new fields. The
result of this is a number of constraint equations among the fields and often
eccentric looking field equations derived from the reduced action. Section 4
has a similar upshot as section 3 but the difference is the action term mixing
is carried out only after extremizing S and prior to any integration by part.
Section 5 pertains to G(x) ontology where various personal views on G(x)
gravity are expressed in the context of the Standard Model fermions (SMF). The
prospect of mitigating gravity field effects for the SMF is investigated at the
end via the variable speed of light (VSL) and new global Lorentz
transformations fusing two upper speeds: the light speed c and a proper maximal
speed given in the text assigned to all point mass mo and involving the Planck
mass. The new LT in combination with VSL also houses a family of special
noninertial frames in linear motions. The (spin sensitive) spacetime and
momentum dependent VSL is modeled via the Hamiltonian formalism with the aim of
canceling the effect of Newtonian gravity felt by a SMF test particle. I also
model variable G for yielding finite gravity at all distances, including zero.
Excising gravity from the SMF rank (via VSL plus G(x), or by gauging to zero
the SMF gravitational masses) has epic brunt on quantum gravity, local SUSY,
superstring models, leptoquarks (if any) and cosmology.

712.0451 | A Reactive Tabu Search Algorithm for Stimuli Generation in
Psycholinguistics | The generation of meaningless "words" matching certain statistical and/or
linguistic criteria is frequently needed for experimental purposes in
Psycholinguistics. Such stimuli receive the name of pseudowords or nonwords in
the Cognitive Neuroscience literatue. The process for building nonwords
sometimes has to be based on linguistic units such as syllables or morphemes,
resulting in a numerical explosion of combinations when the size of the
nonwords is increased. In this paper, a reactive tabu search scheme is proposed
to generate nonwords of variables size. The approach builds pseudowords by
using a modified Metaheuristic algorithm based on a local search procedure
enhanced by a feedback-based scheme. Experimental results show that the new
algorithm is a practical and effective tool for nonword generation.

712.0453 | Induced-charge electrophoresis near an insulating wall | Induced-charge electrophoresis (ICEP) has mostly been analyzed for asymmetric
particles in an infinite fluid, but channel walls in real systems further break
symmetry and lead to dielectrophoresis (DEP) in local field gradients. Zhao and
Bau (Langmuir, \textbf{23}, 2007, pp 4053) recently predicted that a metal
(ideally polarizable) cylinder is repelled from an insulating wall in a DC
field. We revisit this problem with an AC field and show that attraction to the
wall sets in at high frequency and leads to an equilibrium distance, where DEP
balances ICEP, although, in three dimensions, a metal sphere is repelled from
the wall at all frequencies. This conclusion, however, does not apply to
asymmetric particles. Consistent with the recent experiments of Gangwal et al.
(arXiv:0708.2417), we show that a metal/insulator Janus particle is always
attracted to the wall in an AC field. The Janus particle tends to move toward
its insulating end, perpendicular to the field, but ICEP torque rotates this
end toward the wall. Under some conditions, the theory predicts steady
translation along the wall with an equilibrium tilt angle, as seen in
experiments, although more detailed modeling of the contact region of
overlapping double layers is required.

712.0455 | Two Years of INTEGRAL monitoring of GRS 1915+105 Part 2: X-Ray
Spectro-Temporal Analysis | (abridged) This is the second paper presenting the results of two years of
monitoring of GRS 1915+105 with \integral and \rxte and the Ryle Telescope. We
present the X-ray spectral and temporal analysis of four observations which
showed strong radio to X-ray correlations. During one observation GRS 1915+105
was in a steady state, while during the three others it showed cycles of X-ray
dips and spikes (followed by radio flares). We present the time-resolved
spectroscopy of these cyclesand show that in all cases the hard X-ray component
(the Comptonized emission from a coronal medium) is suppressed in coincidence
with a soft X-ray spike that ends the cycle. We interpret these results as
evidence that the soft X-ray spike is the trigger of the ejection, and that the
ejected medium is the coronal material. In the steady state observation, the
X-ray spectrum is indicative of the hard-intermediate state, with the presence
of a relatively strong emission at 15 GHz. The X-ray spectra are the sum of a
Comptonized component and an extra power law extending to energies >200 keV
without any evidence for a cut-off. We observe a possible correlation of the
radio flux with that of the power law component, which may indicate that we see
direct emission from the jet at hard X-ray energies. We study the energy
dependence of a ~4 Hz QPO during the hard-intermediate state observation. The
QPO-``spectrum'' is well modeled by a power law with a cut-off at an energy
about 11 keV that clearly differs from the relative contribution of the
Comptonized component to the overall flux. This may rule out models of global
oscillations of the Compton corona.

712.0456 | Two years of INTEGRAL monitoring of GRS 1915+105 Part 1: multiwavelength
coverage with INTEGRAL, RXTE, and the Ryle radio Telescope | (Abridged) We report the results of monitoring observations of the Galactic
microquasar GRS 1915+105 performed simultaneously with INTEGRAL and RXTE Ryle .
We present the results of the whole \integral campaign, report the sources that
are detected and their fluxes and identify the classes of variability in which
GRS 1915+105 is found. The accretion ejection connections are studied in a
model independent manner through the source light curves, hardness ratio, and
color color diagrams. During a period of steady ``hard'' X-ray state (the
so-called class chi) we observe a steady radio flux. We then turn to 3
particular observations during which we observe several types of soft X-ray
dips and spikes cycles, followed by radio flares. During these observations GRS
1915+105 is in the so-called nu, lambda, and beta classes of variability. The
observation of ejections during class lambda are the first ever reported. We
generalize the fact that a (non-major) discrete ejection always occurs, in GRS
1915+105, as a response to an X-ray sequence composed of a spectrally hard
X-ray dip terminated by an X-ray spike marking the disappearance of the hard
X-ray emission above 18 keV. We also identify the trigger of the ejection as
this X-ray spike. A possible correlation between the amplitude of the radio
flare and the duration of the X-ray dip is found in our data. In this case the
X-ray dips prior to ejections could be seen as the time during which the source
accumulates energy and material that is ejected later.

712.0458 | Inflation in a refined racetrack | In this note, we refine the racetrack inflation model constructed in
arXiv:hep-th/0406230 by including the open string modulus. This modulus encodes
the embedding of our braneworld inside some Calabi-Yau throat. We argue that in
generic this open string modulus dynamically runs with the inflaton field
thanks to its nonlinear coupling. A full analysis becomes difficult because the
scalar potential changes progressively during the inflation epoch.

712.0459 | Large Deviations for Heavy-Tailed Factor Models | We study large deviation probabilities for a sum of dependent random
variables from a heavy-tailed factor model, assuming that the components are
regularly varying. We identify conditions where both the factor and the
idiosyncratic terms contribute to the behaviour of the tail-probability of the
sum. A simple conditional Monte Carlo algorithm is also provided together with
a comparison between the simulations and the large deviation approximation. We
also study large deviation probabilities for stochastic processes with factor
structure. The processes involved are assumed to be Levy processes with
regularly varying jump measures. Based on the results of the first part of the
paper, we show that large deviations on a finite time interval are due to one
large jump that can come from either the factor or the idiosyncratic part of
the process.

712.0461 | Ising model on hyperbolic lattice studied by corner transfer matrix
renormalization group method | We study two-dimensional ferromagnetic Ising model on a series of regular
lattices, which are represented as the tessellation of polygons with p>=5
sides, such as pentagons (p=5), hexagons (p=6), etc. Such lattices are on
hyperbolic planes, which have constant negative scalar curvatures. We calculate
critical temperatures and scaling exponents by use of the corner transfer
matrix renormalization group method. As a result, the mean-field like phase
transition is observed for all the cases p>=5. Convergence of the calculated
transition temperatures with respect to p is investigated towards the limit

712.0464 | The Big Bang quantum cosmology: The matter-energy production epoch | The exactly solvable quantum model of the homogeneous, isotropic and closed
universe in the matter-energy production epoch is considered. It is assumed
that the universe is originally filled with a uniform scalar field and a
perfect fluid which defines a reference frame. The stationary state spectrum
and the wave functions of the quantum universe are calculated. In this model
the matter-energy in the universe has a component in the form of a condensate
of massive zero-momentum excitation quanta of oscillations of primordial scalar
field. The mean value of the scale factor of the universe in a given state is
connected with the mass of a condensate by a linear relation. The nucleation
rate of the universe from the initial cosmological singularity point is
calculated. It is demonstrated that the process of nucleation of the universe
can have an exponential (explosive) nature. The evolution of the universe is

712.0465 | Accelerating Quantum Universe | The origin of negative pressure fluid (the dark energy) is investigated in
the quantum model of the homogeneous, isotropic and closed universe filled with
a uniform scalar field and a perfect fluid which defines a reference frame. The
equations of the model are reduced to the form which allows a direct comparison
between them and the equations of the Einsteinian classical theory of gravity.
It is shown that quantized scalar field has a form of a condensate which
behaves as an antigravitating medium. The theory predicts an accelerating
expansion of the universe even if the vacuum energy density vanishes. An
antigravitating effect of a condensate has a purely quantum nature. It is shown
that the universe with the parameters close to the Planck ones can go through
the period of exponential expansion. The conditions under which in
semi-classical approximation the universe looks effectively like spatially flat
with negative deceleration parameter are determined. The reduction to the
standard model of classical cosmology is discussed.

712.0466 | Semileptonic B decays and the inclusive determination of |V(ub)| | We present a new theoretical framework for the study of $B\to X_u \ell \nu$
decays, which includes all known perturbative and non-perturbative
contributions and a description of leading and subleading Fermi motion effects.
The perturbative and non-perturbative regimes are separated by a ``hard''
Wilsonian cutoff $\mu \sim 1$ GeV. We bring into focus some problems related to
the high $q^2$ region and to Weak Annihilation effects. We provide estimates of

712.0467 | Transport properties in chaotic and non-chaotic many particles systems | Two deterministic models for Brownian motion are investigated by means of
numerical simulations and kinetic theory arguments. The first model consists of
a heavy hard disk immersed in a rarefied gas of smaller and lighter hard disks
acting as a thermal bath. The second is the same except for the shape of the
particles, which is now square. The basic difference of these two systems lies
in the interaction: hard core elastic collisions make the dynamics of the disks
chaotic whereas that of squares is not. Remarkably, this difference is not
reflected in the transport properties of the two systems: simulations show that
the diffusion coefficients, velocity correlations and response functions of the
heavy impurity are in agreement with kinetic theory for both the chaotic and
the non-chaotic model. The relaxation to equilibrium, however, is very
sensitive to the kind of interaction. These observations are used to reconsider
and discuss some issues connected to chaos, statistical mechanics and
diffusion.

712.0468 | Indirect detection of Dark Matter with antimatter: Demystifying the
clumpiness boost factors | The hierarchical scenario of structure formation, in the frame of the
$\Lambda$-CDM cosmology, predicts the existence of dark matter (DM) sub-halos
down to very small scales, of which the minimal size depends on the microscopic
properties of the DM. In the context of annihilating DM, such substructures are
expected to enhance the primary cosmic ray (CR) fluxes originating from DM
annihilation in the Galaxy. This enhancement has long been invoked to allow
predictions of imprints of DM annihilation on the antimatter CR spectra. Taking
advantage of the method developed by Lavalle et al (2007b), we (Lavalle et al,
2007a) accurately compute the boost factors for positrons and anti-protons, as
well as the associated theoretical and statistical errors. To this aim, we use
a compilation of the latest results of cosmological N-body simulations and the

web rankings | PageRank is a ranking of the web pages that measures how often a given web
page is visited by a random surfer on the web graph, for a simple model of web
surfing. It seems realistic that PageRank may also have an influence on the
behavior of web surfers. We propose here a simple model taking into account the
mutual influence between web ranking and web surfing. Our ranking, the
T-PageRank, is a nonlinear generalization of the PageRank. It is defined as the
limit, if it exists, of some nonlinear iterates. A positive parameter T, the
temperature, measures the confidence of the web surfer in the web ranking. We
prove that, when the temperature is large enough, the T-PageRank is unique and
the iterates converge globally on the domain. But when the temperature is
small, there may be several T-PageRanks, that may strongly depend on the
initial ranking. Our analysis uses results of nonlinear Perron-Frobenius
theory, Hilbert projective metric and Birkhoff's coefficient of ergodicity.

712.047 | INTEGRAL and New Classes of High-Mass X-ray Binaries | The gamma-ray observatory INTEGRAL, launched in October 2002, produces a
wealth of discoveries and new results on compact high energy Galactic objects,
nuclear gamma-ray line emission, diffuse line and continuum emission, cosmic
background radiation, AGN and high energy transients. Two important
serendipitous discoveries made by the INTEGRAL mission are new classes of X-ray
binaries, namely the highly-obscured high-mass X-ray binaries, and the

712.0473 | The effect of isospin violation on scalar meson production | We investigate the isospin-violating mixing of the light scalar mesons
a0(980) and f0(980) within the unitarized chiral approach. Isospin-violating
effects are considered to leading order in the quark mass difference and
electromagnetism. In this approach both resonances are generated through
meson-meson dynamics. Our results provide a description of the mixing
phenomenon within a framework consistent with chiral symmetry and unitarity,
where these resonances are not predominantly quark-antiquark states. We discuss
in detail the reactions J/Psi to phi S, where S denotes a suitable pair of
pseudo--scalar mesons in the scalar channel, namely pi0 eta, K+K-, and K0 \bar

712.0475 | Organic versus Hybrid Coacervate Complexes : Co-Assembly and Adsorption
Properties | We report the co-assembly and adsorption properties of coacervate complexes
made from polyelectrolyte-neutral block copolymers and oppositely charged
nanocolloids. The nanocolloids put under scrutiny were ionic surfactant
micelles and highly charged 7 nm cerium oxide (CeO2) nanoparticles. Static and
dynamic light scattering was used to investigate the microstructure and
stability of the organic and hybrid complexes. The microstructure of the
CeO2-based complexes was resolved using cryogenic transmission electronic
microscopy (Cryo-TEM), and it revealed that the cores were clusters made from
densely packed nanoparticles. In the concentration range of interest, c = 10-4
- 1 wt. %, the surfactant-based complexes were shown to exhibit a critical
association concentration (cac) whereas the nanoparticle-polymer hybrids did
not. The adsorption properties of the same complexes were investigated above
the cac by stagnation point adsorption reflectometry. The adsorbed amount was
measured as a function of time for polymers and complexes using anionically
charged silica and hydrophobic poly(styrene) substrates. It was found that all
complexes adsorbed readily on both types of substrates up to a level of 1 - 2
mg m-2 at stationary state. Upon rinsing however, the adsorbed layer was
removed for the surfactant-based systems, but not for the cerium oxide
clusters. As for the solution properties, these finding were interpreted in
terms of a critical association concentrations which are very different for
organic and hybrid complexes.

712.0476 | Million-Degree Plasma Pervading the Extended Orion Nebula | Most stars form as members of large associations within dense, very cold
(10-100 K) molecular clouds. The nearby giant molecular cloud in Orion hosts
several thousand stars of ages less than a few million years, many of which are
located in or around the famous Orion Nebula, a prominent gas structure
illuminated and ionized by a small group of massive stars (the Trapezium). We
present X-ray observations obtained with the X-ray Multi-Mirror satellite
XMM-Newton revealing that a hot plasma with a temperature of 1.7-2.1 million K
pervades the southwest extension of the nebula. The plasma, originating in the
strong stellar winds from the Trapezium, flows into the adjacent interstellar
medium. This X-ray outflow phenomenon must be widespread throughout our Galaxy.

712.0478 | The second law of thermodynamics in the quantum Brownian oscillator at
an arbitrary temperature | In the classical limit no work is needed to couple a system to a bath with
sufficiently weak coupling strength (or with arbitrarily finite coupling
strength for a linear system) at the same temperature. In the quantum domain
this may be expected to change due to system-bath entanglement. Here we show
analytically that the work needed to couple a single linear oscillator with
finite strength to a bath cannot be less than the work obtainable from the
oscillator when it decouples from the bath. Therefore, the quantum second law
holds for an arbitrary temperature. This is a generalization of the previous
results for zero temperature [1,2]; in the high temperature limit we recover
the classical behavior.
| quant-ph | in the classical limit no work is needed to couple a system to a bath with sufficiently weak coupling strength or with arbitrarily finite coupling strength for a linear system at the same temperature in the quantum domain this may be expected to change due to systembath entanglement here we show analytically that the work needed to couple a single linear oscillator with finite strength to a bath cannot be less than the work obtainable from the oscillator when it decouples from the bath therefore the quantum second law holds for an arbitrary temperature this is a generalization of the previous results for zero temperature 12 in the high temperature limit we recover the classical behavior | [['in', 'the', 'classical', 'limit', 'no', 'work', 'is', 'needed', 'to', 'couple', 'a', 'system', 'to', 'a', 'bath', 'with', 'sufficiently', 'weak', 'coupling', 'strength', 'or', 'with', 'arbitrarily', 'finite', 'coupling', 'strength', 'for', 'a', 'linear', 'system', 'at', 'the', 'same', 'temperature', 'in', 'the', 'quantum', 'domain', 'this', 'may', 'be', 'expected', 'to', 'change', 'due', 'to', 'systembath', 'entanglement', 'here', 'we', 'show', 'analytically', 'that', 'the', 'work', 'needed', 'to', 'couple', 'a', 'single', 'linear', 'oscillator', 'with', 'finite', 'strength', 'to', 'a', 'bath', 'can', 'not', 'be', 'less', 'than', 'the', 'work', 'obtainable', 'from', 'the', 'oscillator', 'when', 'it', 'decouples', 'from', 'the', 'bath', 'therefore', 'the', 'quantum', 'second', 'law', 'holds', 'for', 'an', 'arbitrary', 'temperature', 'this', 'is', 'a', 'generalization', 'of', 'the', 'previous', 'results', 'for', 'zero', 'temperature', '12', 'in', 'the', 'high', 'temperature', 'limit', 'we', 'recover', 'the', 'classical', 'behavior']] | [-0.10188684037798999, 0.2088816459262077, -0.07603333421990785, 0.01047786970774078, -0.05798804092133402, -0.17813683040917683, 0.06519108103651904, 0.320721121194462, -0.2684888525897812, -0.263713214896683, 0.062225553321524754, -0.2769136315034543, -0.08026141756707723, 0.21434025025257888, -0.025889654190609884, 0.02278086507661093, 0.02603600040062243, 0.09689770889285411, -0.06640096348073557, -0.22973538361664894, 0.27366501472603816, 0.0646945400418252, 0.2587292908022228, 0.0837783949672539, 0.08550418376460926, -0.011757112613632383, 0.09993692404694027, 0.049413139923897564, -0.09413210540826077, 0.04860090096053293, 0.2416046268553433, -0.007620604915751351, 0.28162828182530963, -0.403263084208354, -0.22531369984802654, 0.1461393212278684, 0.1294829998101689, 0.2037914180690343, 0.016108404059942145, -0.22111337285679886, 0.07133503584589204, -0.18776539929656902, -0.1671578852364268, -0.061908029226793185, 0.0017646490715635128, -0.026152218548724286, -0.2959028930626173, 0.07777648226509237, 0.10526945097690336, 0.0491272679209942, -0.03349557803529832, -0.03171840241441551, 0.011556223397039704, 0.12758577660917161, 0.023455678178966353, 0.04703771859869106, 0.13460440272226548, -0.11395507701374112, -0.043928644798982605, 0.3539807910386186, -0.14711139655065558, -0.21947584175464943, 0.2240921793392119, -0.16911095264964762, -0.09298713960183355, 0.10175845090451086, 0.11681163685921675, 0.10635034833333512, -0.1400088800808154, 0.10490488479885025, 0.015468576349891149, 0.23531318090967515, 0.029842999668266527, 0.05568220455927822, 0.18759039162188515, 0.11010474185300115, 0.09176060169314344, 0.18603350988660866, -0.0460001830306127, -0.11318100040826277, -0.30946368036361843, -0.12794061511571908, -0.25045686326602584, 0.10941228551730915, -0.08777078515730607, -0.14271616213357982, 0.3596999259331288, 0.18909554361389616, 0.19797847925438586, 0.09002150321363384, 0.2848478487223132, 0.1946374953358283, 0.06922303921837583, 0.05970162770941726, 0.2951626010143604, 0.16844837345246577, 0.11982227322191764, -0.2736120610371029, 0.020088865059531398, 0.006783336747246675] |
