709.4135 | Effect of matrix parameters on mesoporous matrix based quantum
computation | We present a solid state implementation of quantum computation, which
improves previously proposed optically driven schemes. Our proposal is based on
vertical arrays of quantum dots embedded in a mesoporous material which can be
fabricated with present technology. We study the feasibility of performing
quantum computation with different mesoporous matrices. We analyse which matrix
materials ensure that each individual stack of quantum dots can be considered
isolated from the rest of the ensemble-a key requirement of our scheme. This
requirement is satisfied for all matrix materials for feasible structure
parameters and GaN/AlN based quantum dots. We also show that one dimensional
ensembles substantially improve performances, even of CdSe/CdS based quantum
dots.

709.4136 | X-ray Emission from Planetary Nebulae and their Central Stars: a Status
Report | In the era of Chandra and XMM-Newton, the detection (or nondetection) of
diffuse and/or point-like X-ray sources within planetary nebulae (PNe) yields
important, unique insight into PN shaping processes. Diffuse X-ray sources,
whether due to ``hot bubbles'' or to collimated outflows or jets, allow us to
probe the energetic shocks within PN wind interaction regions. Meanwhile, X-ray
point sources provide potential diagnostics of magnetic fields, accretion
disks, and/or binary companions at PN cores. Here, I highlight recent X-ray
observational results and trends that have the potential to shed new light on
the origin and evolution of the structure of PNe.

709.4138 | How do the grains slide in fine-grained zirconia polycrystals at high
temperature? | Degradation of mechanical properties of zirconia polycrystals is hardly
discussed in terms of solution-precipitation grain-boundary sliding due to
experimental controversies over imaging of intergranular amorphous phases at
high and room temperatures. Here, the authors applied the techniques of
mechanical spectroscopy and transmission electron microscopy (TEM) to shed

709.4139 | Serendipitous Chandra X-ray Detection of a Hot Bubble within the
Planetary Nebula NGC 5315 | We report the serendipitous detection of the planetary nebula NGC 5315 by the
Chandra X-ray Observatory. The Chandra imaging spectroscopy results indicate
that the X-rays from this PN, which harbors a Wolf-Rayet (WR) central star,
emanate from a T_X ~ 2.5x10^6 K plasma generated via the same wind-wind
collisions that have cleared a compact (~8000 AU radius) central cavity within
the nebula. The inferred X-ray luminosity of NGC 5315 is ~2.5x10^{32} erg
s^{-1} (0.3-2.0 keV), placing this object among the most luminous such ``hot
bubble'' X-ray sources yet detected within PNe. With the X-ray detection of NGC
5315, objects with WR-type central stars now constitute a clear majority of
known examples of diffuse X-ray sources among PNe; all such ``hot bubble'' PN
X-ray sources display well-defined, quasi-continuous optical rims. We therefore
assert that X-ray-luminous hot bubbles are characteristic of young PNe with
large central star wind kinetic energies and closed bubble morphologies.
However, the evidence at hand also suggests that processes such as wind and
bubble temporal evolution, as well as heat conduction and/or mixing of hot
bubble and nebular gas, ultimately govern the luminosity and temperature of
superheated plasma within PNe.

709.4142 | Colloids dragged through a polymer solution: experiment, theory and
simulation | We present micro-rheological measurments of the drag force on colloids pulled
through a solution of lambda-DNA (used here as a monodisperse model polymer)
with an optical tweezer. The experiments show a violation of the
Stokes-Einstein relation based on the independently measured viscosity of the
DNA solution: the drag force is larger than expected. We attribute this to the
accumulation of DNA infront of the colloid and the reduced DNA density behind
the colloid. This hypothesis is corroborated by a simple drift-diffusion model
for the DNA molecules, which reproduces the experimental data surprisingly
well, as well as by corresponding Brownian dynamics simulations.

709.4143 | A weighted network evolution model based on passenger behavior | This paper presents an evolution model of weighted networks in which the
structural growth and weight dynamics are driven by human behavior, i.e.
passenger route choice behavior. Transportation networks grow due to people's
increasing travel demand and the pattern of growth is determined by their route
choice behavior. In airline networks passengers often transfer from a third
airport instead of flying directly to the destination, which contributes to the
hubs formation and finally the scale-free statistical property. In this model
we assume at each time step there emerges a new node with m travel
destinations. Then the new node either connects destination directly with the
probability p or transfers from a third node with the probability 1-p. The
analytical result shows degree and strength both obey power-law distribution
with the exponent between 2.33 and 3 depending on p. The weights also obey
power-law distribution. The clustering coefficient, degree assortatively

system CeRuPO using a Sn flux method. Magnetic susceptibility and electrical
resistivity measurements indicate strong anisotropy of this structurally
layered compound. They evidence that the magnetic moments order
ferromagnetically along the c-direction of the tetragonal unit cell, whereas
the crystal electric field (CEF) anisotropy favors the ab-plane. Therefore,
CeRuPO presents the unusual case within rare earth systems, where the
anisotropy of the interionic exchange interaction overcomes the single ion
anisotropy due to the CEF interaction.

709.4146 | Signatures of non-monotonic d-wave gap in electron-doped cuprates | We address the issue whether the data on optical conductivity and Raman
scattering in electron-doped cuprates below $T_c$ support the idea that the
$d-$wave gap in these materials is non-monotonic along the Fermi surface. We
calculate the conductivity and Raman intensity for elastic scattering, and find
that a non-monotonic gap gives rise to several specific features in optical and
Raman response functions. We argue that all these features are present in the

709.4149 | Wrapped Magnetized Branes: Two Alternative Descriptions? | We discuss two inequivalent ways for describing magnetized D-branes wrapped N
times on a torus T^2. The first one is based on a non-abelian gauge bundle
U(N), while the second one is obtained by means of a Narain T-duality
transformation acting on a theory with non-magnetized branes. We construct in
both descriptions the boundary state and the open string vertices and show that
they give rise to different string amplitudes. In particular, the description

of fragmentation. By use of molecular dynamics simulations, we study the impact
fragmentation of a solid disk of interacting particles with a wall. Regardless
of the particular form of the interaction potential, the fragment size
distribution exhibits a power law behaviour with an exponent that increases
logarithmically with the energy deposited in the system, in agreement with
experiments. We expect this behaviour to be generic in fragmentation phenomena.

709.4151 | Universal description of the rotational-vibrational spectrum of three
particles with zero-range interactions | A comprehensive universal description of the rotational-vibrational spectrum
for two identical particles of mass $m$ and the third particle of the mass
$m_1$ in the zero-range limit of the interaction between different particles is
given for arbitrary values of the mass ratio $m/m_1$ and the total angular
momentum $L$. If the two-body scattering length is positive, a number of
vibrational states is finite for $L_c(m/m_1) \le L \le L_b(m/m_1)$, zero for
$L>L_b(m/m_1)$, and infinite for $L<L_c(m/m_1)$. If the two-body scattering
length is negative, a number of states is either zero for $L \ge L_c(m/m_1)$ or
infinite for $L<L_c(m/m_1)$. For a finite number of vibrational states, all the
binding energies are described by the universal function $\epsilon_{LN}(m/m_1)
= {\cal E}(\xi, \eta)$, where $\xi=\displaystyle\frac{N-1/2}{\sqrt{L(L + 1)}}$,
$\eta=\displaystyle\sqrt{\frac{m}{m_1 L (L + 1)}}$,and $N$ is the vibrational
quantum number. This scaling dependence is in agreement with the numerical
calculations for $L > 2$ and only slightly deviates from those for $L = 1, 2$.
The universal description implies that the critical values $L_c(m/m_1)$ and
$L_b(m/m_1)$ increase as $0.401 \sqrt{m/m_1}$ and $0.563 \sqrt{m/m_1}$,
respectively, while a number of vibrational states for $L \ge L_c(m/m_1)$ is
within the range $N \le N_{max} \approx 1.1 \sqrt{L(L+1)}+1/2$.

709.4152 | Cosmological implications of the KATRIN experiment | The upcoming Karlsruhe Tritium Neutrino (KATRIN) experiment will put
unprecedented constraints on the absolute mass of the electron neutrino,
$\mnue$. In this paper we investigate how this information on $\mnue$ will
affect our constraints on cosmological parameters. We consider two scenarios;
one where $\mnue=0$ (i.e., no detection by KATRIN), and one where
$\mnue=0.3$eV. We find that the constraints on $\mnue$ from KATRIN will affect
estimates of some important cosmological parameters significantly. For example,
the significance of $n_s<1$ and the inferred value of $\Omega_\Lambda$ depend
on the results from the KATRIN experiment.

709.4153 | Finite Element Formalism for Micromagnetism | The aim of this work is to present the details of the finite element approach
we developed for solving the Landau-Lifschitz-Gilbert equations in order to be
able to treat problems involving complex geometries. There are several
possibilities to solve the complex Landau-Lifschitz-Gilbert equations
numerically. Our method is based on a Galerkin-type finite element approach. We
start with the dynamic Landau-Lifschitz-Gilbert equations, the associated
boundary condition and the constraint on the magnetization norm. We derive the
weak form required by the finite element method. This weak form is afterwards
integrated on the domain of calculus. We compared the results obtained with our
finite element approach with the ones obtained by a finite difference method.
The results being in very good agreement, we can state that our approach is
well adapted for 2D micromagnetic systems.

709.4155 | Photonuclear reactions of actinide and pre-actinide nuclei at
intermediate energies | Photonuclear reaction is described with an approach based on the
quasideuteron nuclear photoabsorption model followed by the process of
competition between light particle evaporation and fission for the excited
nucleus. Thus fission process is considered as a decay mode. The
evaporation-fission process of the compound nucleus is simulated in a
Monte-Carlo framework. Photofission reaction cross sections are analysed in a
systematic manner in the energy range $\sim$~50-70 MeV for the actinides
$^{232}$Th, $^{233}$U, $^{235}$U, $^{238}$U and $^{237}$Np and the pre-actinide
nuclei $^{208}$Pb and $^{209}$Bi. The study reproduces satisfactorily well the
available experimental data of photofission cross sections at energies
$\sim$~50-70 MeV and the increasing trend of nuclear fissility with the
fissility parameter $Z^2/A$ for the actinides and pre-actinides at intermediate
energies [$\sim$~20-140 MeV].

correlated and are thus shown to be affiliated with local doping domains. We
investigate the position of the 2D line -- the most significant Raman peak to
identify single-layer graphene -- as a function of charging up to |n|~4 10^12
cm^-2. Contrary to the G line which exhibits a strong and symmetric stiffening
with respect to electron and hole-doping, the 2D line shows a weak and slightly
asymmetric stiffening for low doping. Additionally, the line width of the 2D
line is, in contrast to the G line, doping-independent making this quantity a
reliable measure for identifying single-layer graphene.

709.4158 | Infrared spectroscopic diagnostics for Active Galactic Nuclei | Infrared spectroscopy in the mid- and far-infrared provides powerful
diagnostics for studying the emission regions in active galaxies. The large
variety of ionic fine structure lines can probe gas conditions in a variety of
physical conditions, from highly ionized gas excited by photons originated by
black hole accretion to gas photoionized by young stellar systems. The critical
density and the ionization potential of these transitions allow to fully cover
the density-ionization parameter space. Some examples of line ratios diagrams
using both mid-infrared and far-infrared ionic fine structure lines are
presented. The upcoming space observatory Herschel will be able to observe the
far-infrared spectra of large samples of local active galaxies. Based on the
observed near-to-far infrared emission line spectrum of the template galaxy
NGC1068, are presented the predictions for the line fluxes expected for
galaxies at high redshift. To observe spectroscopically large samples of
distant galaxies, we will have to wait fot the future space missions, like
SPICA and, ultimately, FIRI.

709.4159 | Torques on Spheroidal Silicate Grains Exposed to Anisotropic
Interstellar Radiation Fields | Radiative torques, due to the absorption and scattering of starlight, are
thought to play a major role in the alignment of grains with the interstellar
magnetic field. The absorption of radiation also gives rise to recoil torques,
associated with the photoelectric effect and photodesorption. The recoil
torques are much more difficult to model and compute than the direct radiative
torque. Here, we consider the relatively simple case of a spheroidal grain.
Given our best estimates for the photoelectric yield and other relevant grain
physical properties, we find that the recoil torques contribute at the 10%
level or less compared with the direct radiative torque. We recommend that the
recoil torques not be included in models of radiation-driven grain alignment at
this time. However, additional experimental characterization of the surface

quantify the magnitude of these torques.
| astro-ph | radiative torques due to the absorption and scattering of starlight are thought to play a major role in the alignment of grains with the interstellar magnetic field the absorption of radiation also gives rise to recoil torques associated with the photoelectric effect and photodesorption the recoil torques are much more difficult to model and compute than the direct radiative torque here we consider the relatively simple case of a spheroidal grain given our best estimates for the photoelectric yield and other relevant grain physical properties we find that the recoil torques contribute at the 10 level or less compared with the direct radiative torque we recommend that the recoil torques not be included in models of radiationdriven grain alignment at this time however additional experimental characterization of the surface properties and photoelectric yield for submicron grains is needed to better quantify the magnitude of these torques | [['radiative', 'torques', 'due', 'to', 'the', 'absorption', 'and', 'scattering', 'of', 'starlight', 'are', 'thought', 'to', 'play', 'a', 'major', 'role', 'in', 'the', 'alignment', 'of', 'grains', 'with', 'the', 'interstellar', 'magnetic', 'field', 'the', 'absorption', 'of', 'radiation', 'also', 'gives', 'rise', 'to', 'recoil', 'torques', 'associated', 'with', 'the', 'photoelectric', 'effect', 'and', 'photodesorption', 'the', 'recoil', 'torques', 'are', 'much', 'more', 'difficult', 'to', 'model', 'and', 'compute', 'than', 'the', 'direct', 'radiative', 'torque', 'here', 'we', 'consider', 'the', 'relatively', 'simple', 'case', 'of', 'a', 'spheroidal', 'grain', 'given', 'our', 'best', 'estimates', 'for', 'the', 'photoelectric', 'yield', 'and', 'other', 'relevant', 'grain', 'physical', 'properties', 'we', 'find', 'that', 'the', 'recoil', 'torques', 'contribute', 'at', 'the', '10', 'level', 'or', 'less', 'compared', 'with', 'the', 'direct', 'radiative', 'torque', 'we', 'recommend', 'that', 'the', 'recoil', 'torques', 'not', 'be', 'included', 'in', 'models', 'of', 'radiationdriven', 'grain', 'alignment', 'at', 'this', 'time', 'however', 'additional', 'experimental', 'characterization', 'of', 'the', 'surface', 'properties', 'and', 'photoelectric', 'yield', 'for', 'submicron', 'grains', 'is', 'needed', 'to', 'better', 'quantify', 'the', 'magnitude', 'of', 'these', 'torques']] | [-0.05112073096137315, 0.13078122719969243, -0.04425048179388659, 0.05992539621226183, -0.10462630793335848, -0.05347161680740649, -0.0010628567702353818, 0.4113089453990329, -0.24733184534443975, -0.35586477254759774, 0.01274283702185454, -0.2848807579059511, -0.06571474865920944, 0.22597956234806102, -0.00872239589448763, -0.003382687656247146, 0.02961600188816553, -0.07516198611040026, -0.02227518414402355, -0.20136692293135017, 0.29254148705313876, 0.12944573232559614, 0.17102335967212814, 0.08450174902498798, 0.043592150426351735, -0.04644219326301899, -0.05414426702151254, -0.02023591448820821, -0.16348157250148976, 0.0858928217322961, 0.18375136310742288, -0.022298092609398985, 0.1520477991028089, -0.5139957386107273, -0.2064240434540321, 0.08134163256211538, 0.11290341890608407, 0.15594632478992212, -0.08870150764005925, -0.19306482245574694, 0.0208256872767927, -0.1830380130304049, -0.09984080605081296, -0.0399396345306392, 0.06121216762622767, -0.012852550441182333, -0.29933541836472205, 0.10238667546068989, 0.10610265659219394, 0.03650886548861657, -0.1062044232177918, -0.14375331918453824, -0.08297368711377302, 0.1014671455064074, 0.06158442745521052, 0.03241586942350881, 0.23216810104698707, -0.15498593413073264, -0.07319360216186471, 0.44828035355839013, -0.044171387003276226, -0.1550670003579062, 0.21882587265580483, -0.21551690030562348, -0.05239680294610866, 0.22112008464548175, 0.17928939168532826, 0.14317473488834317, -0.13641751350353357, -0.02262725420686901, 0.04157824410533864, 0.14280946291536603, 0.04866811182758171, 0.07850987108564642, 0.2656629568169991, 0.1386675476909883, 0.028592584088559532, 0.10930762101205589, -0.17775609463250763, -0.03619506312151478, -0.23670556163415313, -0.14298900418391783, -0.13012223408161983, 0.0800308881135943, -0.10007634696984036, -0.13337755143923097, 0.30337366002312005, 0.21187826514575783, 0.18738271664726, 0.02685797465199681, 0.35379337728635907, 0.1214540108682728, 0.12677874266846131, 0.05655782178286718, 0.3547456435546636, 0.14373263348633908, 0.07120897732547497, -0.32389639514779084, 0.13134515581154965, -0.016932575988953244] |
709.416 | Origin of the abundance patterns in Galactic globular clusters:
constraints on dynamical and chemical properties of globular clusters | Aims. We analyse the effects of a first generation of fast rotating massive
stars on the dynamical and chemical properties of globular clusters. Methods.
We use stellar models of fast rotating massive stars, losing mass through a
slow mechanical equatorial winds to produce material rich in H-burning
products. We propose that stars with high Na and low O abundances (hereafter
anomalous stars) are formed from matter made of slow winds of individual
massive stars and of interstellar matter. The proportion of slow wind and of
interstellar material is fixed in order to reproduce the observed Li-Na
anticorrelation in NGC 6752. Results. In the case that globular clusters,
during their lifetime, did not lose any stars, we found that to reproduce the
observed ratio of normal to anomalous stars, a flat initial mass function (IMF)
is needed, with typically a slope x=0.55 (a Salpeter's IMF has x=1.35). In the
case that globular clusters suffer from an evaporation of normal stars, the IMF
slope can be steeper: to have x=1.35, about 96% of the normal stars would be
lost. We make predictions for the distribution of stars as a function of their
[O/Na] and obtain quite reasonable agreement with that one observed for NGC
6752. Predictions for the number fraction of stars with different values of
helium, of the 12C/13C and 16O/17O ratios are discussed, as well as the
expected relations between values of [O/Na] and those of helium, of [C/N], of
12C/13C and of 16O/17O. Future observations might test these predictions. We
also provide predictions for the present day mass of the clusters expressed in
units of mass of the gas used to form stars, and for the way the present day
mass is distributed between the first and second generation of stars and the
stellar remnants.

709.4161 | Galactic Rotation Parameters from Data on Open Star Clusters | Currently available data on the field of velocities Vr, Vl, Vb for open star
clusters are used to perform a kinematic analysis of various samples that
differ by heliocentric distance, age, and membership in individual structures
(the Orion, Carina--Sagittarius, and Perseus arms). Based on 375 clusters
located within 5 kpc of the Sun with ages up to 1 Gyr, we have determined the
Galactic rotation parameters
Wo =-26.0+-0.3 km/s/kpc,
W'o = 4.18+-0.17 km/s/kpc^2,
W''o=-0.45+-0.06 km/s/kpc^3, the system contraction parameter K = -2.4+-0.1
km/s/kpc, and the parameters of the kinematic center Ro =7.4+-0.3 kpc and lo =
0+-1 degrees. The Galactocentric distance Ro in the model used has been found
to depend significantly on the sample age. Thus, for example, it is 9.5+-0.7
kpc and 5.6+-0.3 kpc for the samples of young (<50 Myr) and old (>50 Myr)
clusters, respectively. Our study of the kinematics of young open star clusters
in various spiral arms has shown that the kinematic parameters are similar to
the parameters obtained from the entire sample for the Carina-Sagittarius and
Perseus arms and differ significantly from them for the Orion arm. The
contraction effect is shown to be typical of star clusters with various ages.
It is most pronounced for clusters with a mean age of 100 Myr, with the
contraction velocity being Kr = -4.3+-1.0 km/s.

709.4162 | Benchmark density functional theory calculations for nano-scale
conductance | We present a set of benchmark calculations for the Kohn-Sham elastic
transmission function of five representative single-molecule junctions. The
transmission functions are calculated using two different density functional
theory (DFT) methods, namely an ultrasoft pseudopotential plane wave code in
combination with maximally localized Wannier functions, and the norm-conserving
pseudopotential code Siesta which applies an atomic orbital basis set. For all
systems we find that the Siesta transmission functions converge toward the
plane-wave result as the Siesta basis is enlarged. Overall, we find that an
atomic basis with double-zeta and polarization is sufficient (and in some cases
even necessary) to ensure quantitative agreement with the plane-wave
calculation. We observe a systematic down shift of the Siesta transmission
functions relative to the plane-wave results. The effect diminishes as the
atomic orbital basis is enlarged, however, the convergence can be rather slow.

709.4164 | Compound-specific isotope analysis | The isotopic composition, for example, 14C/12C, 13C/12C, 2H/1H, 15N/14N and
18O/16O, of the elements of matter is heterogeneous. It is ruled by physical,
chemical and biological mechanisms. Isotopes can be employed to follow the fate
of mineral and organic compounds during biogeochemical transformations. The
determination of the isotopic composition of organic substances occurring at
trace level in very complex mixtures such as sediments, soils and blood, has
been made possible during the last 20 years due to the rapid development of
molecular level isotopic techniques. After a brief glance at pioneering studies
revealing isotopic breakthroughs at the molecular and intramolecular levels,

709.4166 | Timescale effect estimation in time-series studies of air pollution and
health: A Singular Spectrum Analysis approach | A wealth of epidemiological data suggests an association between
mortality/morbidity from pulmonary and cardiovascular adverse events and air
pollution, but uncertainty remains as to the extent implied by those
associations although the abundance of the data. In this paper we describe an
SSA (Singular Spectrum Analysis) based approach in order to decompose the
time-series of particulate matter concentration into a set of exposure
variables, each one representing a different timescale. We implement our
methodology to investigate both acute and long-term effects of $PM_{10}$

709.4168 | Two-phonon assisted exciton spin relaxation due to exchange interaction
in spherical quantum dots | Spin relaxation in undoped quasi-spherical CdS quantum dots at zero magnetic
fields is investigated using time- and polarization-resolved transient
absorption measurements. Unlike in previous studies of these systems, the
measured signals were corrected for spin-insensitive contributions to the
exciton bleaching dynamics, {allowing us to determine} the pure spin-related
exciton dynamics. To explain the observed room-temperature spin-relaxation time
of several nanoseconds, we propose a novel mechanism based on intralevel
exciton transitions with the emission of one LO phonon, the absorption of
another LO phonon, and an electron spin flip, which is driven by the
electron-hole exchange interaction. The transition rates, calculated in the
present work for different sizes of quantum dots and temperatures, are in fair
agreement with our experimental results.

formed between static quarks and anti-quarks in three dimensional SU(2) lattice
gauge theory. We compare our simulation data with the predictions of both
effective string models as well as perturbation theory. On the string side we
obtain clear evidence for convergence of data to predictions of Nambu-Goto
theory. We comment on the scales at which the static potential starts departing
from one loop perturbation theory and then again being well described by
effective string theories. We also estimate the leading corrections to the
one-loop perturbative potential as well as the Nambu-Goto effective string. In
the intermediate regions we find an empirical formula which gives surprisingly
good fits.

only Strichartz estimates can give a result, with a smallness assumption.

compensated collinear antiferromagnet (AFM) in the presence of spin-polarised
current. The model is based on the assumption that AFM spins are localised and
spin torque is transferred to each magnetic sublattice independently. It is
shown that in AFM spin current i) can be a source of the "negative friction";
and ii) modifies spin-wave frequencies. Equilibrium state of AFM can be
destabilized by the current polarized in parallel to AFM vector. Threshold
current at which the loss of stability takes place depends upon the magnetic
anisotropy of AFM.

709.4173 | An Alternative Form of the Functional Equation for Riemann's Zeta
Function | In this paper we present a simple method for deriving an alternative form of
the functional equation for Riemann's Zeta function. The connections between
some functional equations obtained implicitly by Leonhard Euler in his work
"Remarques sur un beau rapport entre les series des puissances tant directes
que reciproques" in Memoires de l'Academie des Sciences de Berlin 17, (1768),
permit to define a special function, named A(s), which is fully symmetric and
is similar to Riemann's "XI" function. To be complete we find several integral
representations of the A(s) function and as a direct consequence of the second
integral representation we obtain also an analytic continuation of the same
function using an identity of Ramanujan.

709.4174 | Angular Distributions of B -> K ll Decays | We model-independently analyze the angular distributions of B -> K ll decays,
l = e, mu, for low dilepton mass using QCD factorization. Besides the decay
rate, we study the forward-backward asymmetry A_FB^l and a further observable,
F_H^l, which gives rise to a flat term in the angular distribution. We find
that in the Standard Model F_H^l ~ m_l^2, hence vanishing F_H^e and F_H^mu of
around 2% (exact value depends on cuts) with a very small theoretical
uncertainty of a few percent. We also give predictions for R_K, the ratio of B
-> K mu mu to B -> K ee decay rates. We analytically show using large recoil
symmetry relations that in the Standard Model R_K equals one up to lepton mass
corrections of the order 10^(-4). The New Physics reach of the observables from
the B -> K ll angular analysis is explored together with R_K and the B_s -> ll
and B -> X_s ll branching ratios for both l = e and l = mu. We find substantial
room for signals from (pseudo-) scalar and tensor interactions beyond the
Standard Model. Experimental investigations of the B -> K mu mu angular
distributions are suitable for the LHC environment and high luminosity B
factories, where also studies of the electron modes are promising.

709.4177 | Detailed Spectral Modeling of a 3-D Pulsating Reverse Detonation Model:
Too Much Nickel | We calculate detailed NLTE synthetic spectra of a Pulsating Reverse
Detonation (PRD) model, a novel explosion mechanism for Type Ia supernovae.
While the hydro models are calculated in 3-D, the spectra use an angle averaged
hydro model and thus some of the 3-D details are lost, but the overall average
should be a good representation of the average observed spectra. We study the
model at 3 epochs: maximum light, seven days prior to maximum light, and 5 days
after maximum light. At maximum the defining Si II feature is prominent, but
there is also a prominent C II feature, not usually observed in normal SNe Ia
near maximum. We compare to the early spectrum of SN 2006D which did show a
prominent C II feature, but the fit to the observations is not compelling.
Finally we compare to the post-maximum UV+optical spectrum of SN 1992A. With
the broad spectral coverage it is clear that the iron-peak elements on the
outside of the model push too much flux to the red and thus the particular PRD

709.4179 | Relaxational dynamics in 3D randomly diluted Ising models | We study the purely relaxational dynamics (model A) at criticality in
three-dimensional disordered Ising systems whose static critical behaviour
belongs to the randomly diluted Ising universality class. We consider the
site-diluted and bond-diluted Ising models, and the +- J Ising model along the
paramagnetic-ferromagnetic transition line. We perform Monte Carlo simulations
at the critical point using the Metropolis algorithm and study the dynamic
behaviour in equilibrium at various values of the disorder parameter. The
results provide a robust evidence of the existence of a unique model-A dynamic
universality class which describes the relaxational critical dynamics in all
considered models. In particular, the analysis of the size-dependence of
suitably defined autocorrelation times at the critical point provides the
estimate z=2.35(2) for the universal dynamic critical exponent. We also study
the off-equilibrium relaxational dynamics following a quench from T=\infty to
T=T_c. In agreement with the field-theory scenario, the analysis of the

the cross current flowing perpendicular to the nanowires, and observed

709.4181 | Violation of the Wiedemann-Franz Law in a Single-Electron Transistor | We study the influence of Coulomb interaction on the thermoelectric transport
coefficients for a metallic single-electron transistor. By performing a
perturbation expansion up to second order in the tunnel-barrier conductance, we
include sequential and cotunneling processes as well as quantum fluctuations
that renormalize the charging energy and the tunnel conductance. We find that
Coulomb interaction leads to a strong violation of the Wiedemann-Franz law: the
Lorenz ratio becomes gate-voltage dependent for sequential tunneling, and is

709.4186 | The Accretion Flows and Evolution of Magnetic Cataclysmic Variables | We have used a model of magnetic accretion to investigate the accretion flows
of magnetic cataclysmic variables. Numerical simulations demonstrate that four
types of flow are possible: discs, streams, rings and propellers. The
fundamental observable determining the accretion flow, for a given mass ratio,
is the spin-to-orbital period ratio of the system. If IPs are accreting at
their equilibrium spin rates, then for a mass ratio of 0.5, those with
Pspin/Porb < 0.1 will be disc-like, those with 0.1 < Pspin/Porb < 0.6 will be
stream-like, and those with Pspin/Porb ~ 0.6 will be ring-like. The spin to
orbital period ratio at which the systems transition between these flow types
increases as the mass ratio of the stellar components decreases.
For the first time we present evolutionary tracks of mCVs which allow
investigation of how their accretion flow changes with time. As systems evolve
to shorter orbital periods and smaller mass ratios, in order to maintain spin
equilibrium, their spin-to-orbital period ratio will generally increase. As a
result, the relative occurrence of ring-like flows will increase, and the
occurrence of disc-like flows will decrease, at short orbital periods. The
growing number of systems observed at high spin-to-orbital period ratios with
orbital periods below 2h, and the observational evidence for ring-like
accretion in EX Hya, are fully consistent with this picture.

709.4187 | A Semiclassical String Description of Wilson Loop with Local Operators | We discuss a semiclassical string description to circular Wilson loops
without/with local operator insertions. By considering a semiclassical
approximation of type IIB string theory on AdS_5 X S^5 around the corresponding
classical solutions, quadratic actions with respect to fluctuations are
computed. Then the dual corresponding operators describing the fluctuations are
discussed from the point of view of a small deformation of the Wilson loops.
The result gives new evidence for AdS/CFT correspondence.

709.4188 | Charge imbalance and Josephson effects in superconductor-normal metal
mesoscopic structures | We consider a $SBS$ Josephson junction the superconducting electrodes $S$ of
which are in contact with normal metal reservoirs ($B$ means a barrier). For
temperatures near $T_{c}$ we calculate an effective critical current $%
I_{c}^{\ast}$ and the resistance of the system at the currents $I<$ $%
I_{c}^{\ast}$ and $I>>I_{c}^{\ast}$. It is found that the charge imbalance,
which arises due to injection of quasiparticles from the $N$ reservoirs into
the $S$ wire, affects essentially the characteristics of the structure. The
effective critical current $I_{c}^{\ast}$ is always larger than the critical
current $I_{c}$ in the absence of the normal reservoirs and increases with
decreasing the ratio of the length of the $S$ wire $2L$ to the charge imbalance
relaxation length $l_{Q}$. It is shown that a series of peaks arises on the
$I-V$ characteristics due to excitation of the Carlson-Goldman collective
modes. We find the position of Shapiro steps which deviates from that given by
the Josephson relation.

709.4189 | Strong homotopy inner product of an A-infinity algebra | We introduce a strong homotopy notion of a cyclic symmetric inner product of
an A-infinity algebra and prove a characterization theorem in the formalism of
the infinity inner products by Tradler. We also show that it is equivalent to
the notion of a non-constant symplectic structure on the corresponding formal
non-commutative supermanifold. We show that (open Gromov-Witten type) potential
for a cyclic filtered A-infinity algebra is invariant under the cyclic filtered

709.4192 | Parametrization of the Driven Betatron Oscillation | An AC dipole is a magnet which produces a sinusoidally oscillating dipole
field and excites coherent transverse beam motion in a synchrotron. By
observing this coherent motion, the optical parameters can be directly measured
at the beam position monitor locations. The driven oscillation induced by an AC
dipole will generate a phase space ellipse which differs from that of the free
oscillation. If not properly accounted for, this difference can lead to a
misinterpretation of the actual optical parameters, for instance, of 6% or more
in the cases of the Tevatron, RHIC, or LHC. The effect of an AC dipole on the
linear optics parameters is identical to that of a thin lens quadrupole. By
introducing a new amplitude function to describe this new phase space ellipse,
the motion produced by an AC dipole becomes easier to interpret. Beam position
data taken under the influence of an AC dipole, with this new interpretation in
mind, can lead to more precise measurements of the normal Courant-Snyder
parameters. This new parameterization of the driven motion is presented and is
used to interpret data taken in the FNAL Tevatron using an AC dipole.

free oscillation if not properly accounted for this difference can lead to a misinterpretation of the actual optical parameters for instance of 6 or more in the cases of the tevatron rhic or lhc the effect of an ac dipole on the linear optics parameters is identical to that of a thin lens quadrupole by introducing a new amplitude function to describe this new phase space ellipse the motion produced by an ac dipole becomes easier to interpret beam position data taken under the influence of an ac dipole with this new interpretation in mind can lead to more precise measurements of the normal courantsnyder parameters this new parameterization of the driven motion is presented and is used to interpret data taken in the fnal tevatron using an ac dipole | [['an', 'ac', 'dipole', 'is',

709.4194 | Microscopic theory of the Casimir force at thermal equilibrium:
large-separation asymptotics | We present an entirely microscopic calculation of the Casimir force $f(d)$
between two metallic plates in the limit of large separation $d$. The models of
metals consist of mobile quantum charges in thermal equilibrium with the photon
field at positive temperature $T$. Fluctuations of all degrees of freedom,
matter and field, are treated according to the principles of quantum
electrodynamics and statistical physics without recourse to approximations or
intermediate assumptions. Our main result is the correctness of the asymptotic
universal formula $ f(d) \sim -\frac{\zeta(3) \kB T}{8\pi d^3}$, $d\to\infty$.
This supports the fact that, in the framework of Lifshitz' theory of
electromagnetic fluctuations, transverse electric modes do not contribute in

709.4195 | Monte Carlo studies of the VERITAS array of Cherenkov telescopes | VERITAS is a system of four imaging Cherenkov telescopes located at the Fred
Lawrence Whipple Observatory in southern Arizona. We present here results of
detailed Monte Carlo simulations of the array response to extensive air
showers. Cherenkov image and shower parameter distributions are calculated and
show good agreement with distributions obtained from observations of background
cosmic rays and high-energy gamma-rays. Cosmic-ray and gamma-ray rates are
accurately predicted by the simulations. The energy threshold of the
3-telescope system is about 150 GeV after gamma-hadron separation cuts; the
detection rate after gamma-selection cuts for the Crab Nebula is 7.5
gamma's/min. The three-telescope system is able to detect a source with a flux
equivalent to 10% of the Crab Nebula flux in 1.2 h of observations (5 sigma
detection).

709.4196 | Tensor Meson Production in Proton-Proton Collisions from the Color Glass
Condensate | We compute the inclusive cross-section of $f_{2}$ tensor mesons production in
proton-proton collisions at high-energy. We use an effective theory inspired
from the tensor meson dominance hypothesis that couples gluons to $f_{2}$
mesons. We compute the differential cross-section in the
$k_{\perp}$-factorization and in the Color Glass Condensate formalism in the
low density regime. We show that the two formalisms are equivalent for this
specific observable. Finally, we study the phenomenology of $f_{2}$ mesons by
comparing theoretical predictions of different parameterizations of the
unintegrated gluon distribution function. We find that $f_{2}$-meson production

709.4197 | Search for supernova-produced 60Fe in a marine sediment | An 60Fe peak in a deep-sea FeMn crust has been interpreted as due to the
signature left by the ejecta of a supernova explosion close to the solar system
2.8 +/- 0.4 Myr ago [Knie et al., Phys. Rev. Lett. 93, 171103 (2004)]. To
confirm this interpretation with better time resolution and obtain a more
direct flux estimate, we measured 60Fe concentrations along a dated marine
sediment. We find no 60Fe peak at the expected level from 1.7 to 3.2 Myr ago.
However, applying the same chemistry used for the sediment, we confirm the 60Fe
signal in the FeMn crust. The cause of the discrepancy is discussed.

709.4198 | Quantized Detector Networks: A review of recent developments | QDN (quantized detector networks) is a description of quantum processes in
which the principal focus is on observers and their apparatus, rather than on
states of SUOs (systems under observation). It is a realization of Heisenberg's
original instrumentalist approach to quantum physics and can deal with time
dependent apparatus, multiple observers and inter-frame physics. QDN is most
naturally expressed in the mathematical language of quantum computation, a
language ideally suited to describe quantum experiments as processes of
information exchange between observers and their apparatus. Examples in quantum
optics are given, showing how the formalism deals with quantum interference,
non-locality and entanglement. Particle decays, relativity and non-linearity in
quantum mechanics are discussed.

underdoped cuprates | Inelastic neutron scattering data for YBaCuO as well as for LaSrCuO indicate
incommensurate neutron scattering peaks with incommensuration $\delta(x)$ away
from the $(\pi,\pi)$ point. $T_c(x)$ can be replotted as a linear function of
the incommensuration for these materials. This linear relation implies that the
constant that relates these two quantities, one being the incommensuration
(momentum) and another being $T_c(x)$ (energy), has the dimension of velocity
we denote $v^*$: $k_B T_c(x) = \hbar v^* \delta(x)$. We argue that this
experimentally derived relation can be obtained in a simple model of Josephson
coupled stripes. Within this framework we address the role of the $O^{16} \to
O^{18}$ isotope effect on the $T_c(x)$. We assume that the incommensuration is
set by the {\em doping} of the sample and is not sensitive to the oxygen
isotope given the fixed doping. We find therefore that the only parameter that
can change with O isotope substitution in the relation $T_c(x) \sim \delta(x)$
is the velocity $v^*$. We predict an oxygen isotope effect on $v^*$ and expect
it to be $\simeq 5%$.

709.42 | Copy Number Variants and Segmental Duplications Show Different Formation
Signatures | In addition to variation in terms of single nucleotide polymorphisms (SNPs),
whole regions ranging from several kilobases up to a megabase in length differ
in copy number among individuals. These differences are referred to as Copy
Number Variants (CNVs) and extensive mapping of these is underway. Recent
studies have highlighted their great prevalence in the human genome. Segmental
Duplications (SDs) are long (>1kb) stretches of duplicated DNA with high
sequence identity. First, we analyzed the co-localization of SDs and find that
SDs are significantly co-localized with each other, resulting in a power-law
distribution, which suggests a preferential attachment mechanism, i.e. existing
SDs are likely to be involved in creating new ones nearby. Second, we look at
the relationship of CNVs/SDs with various types of repeats. We we find that the
previously recognized association of SDs with Alu elements is significantly
stronger for older SDs and is sharply decreasing for younger ones. While it
might be expected that the patterns should be similar for SDs and CNVs, we
find, surprisingly, no association of CNVs with Alu elements. This trend is
consistent with the decreasing correlation between Alu elements and younger
SDs, the activity of Alu elements has been decreasing and by now it they seem
no longer active. Furthermore, we find a striking association of SDs with
processed pseudogenes suggesting that they may also have mediated SD formation.
Moreover, find strong association with microsatellites for both SDs and CNVs
that suggests a role for satellites in the formation of both.

709.4201 | Consequences of the Production of Very Massive Magnetically Charged
Leptons Early in the Universe and Their Decays to a New Set of Extremely
Massive Neutrinos | We examine the production and decay of extremely heavy magnetically charged
leptons, (tau_g and mu_g), to their own very heavy mu_g and e_g plus their own
new species of neutrinos, nu_g and nubar_g, at some time early in the universe
which could be present in space and, attracted gravitationally towards and
passing through astronomical objects, annihilated with each other to produce
large numbers of photons. Further, we describe the possibility of presently
detecting the bursts of such photons, of three different total energies, in the
seas or oceans on earth.

Theories predicts the existence of colored states in the Higgs multiplets and
calls for two extra generations of Higgs-like fields ('unhiggses'). If these
states are present near the TeV scale, gauge-coupling unification points to the
existence of two distinct scales, 10^15 GeV where right-handed neutrinos and a
Pati-Salam symmetry appear, and 10^18 GeV where complete unification is
achieved. Baryon-number conservation, while not guaranteed, can naturally
emerge from an underlying flavor symmetry. Collider signatures and dark-matter
physics may be drastically different from the conventional MSSM.

709.4205 | Comment on: Competing Interactions, the Renormalization Group, and the
Isotropic-Nematic Phase Transition, by D. Barci and D. Stariolo, Phys. Rev.
Lett. 98, 200604 (2007) | In a recent PRL Barci and Stariolo (BS) generalized the well known Brazovskii
model to include an additional rotationally invariant quartic interaction and
study this model in two dimensions (2d). Depending on the parameters of the
model, BS find two transitions: a first order isotropic-lamellar (striped) or a
second order isotropic-nematic (which they speculate to be in the
Kosterlitz-Thouless universality class). Using a simple symmetry argument, I
show that the striped phase found by BS can not exist in 2d. Furthermore, I
argue that based on the coarse-grained action used by BS it is impossible to
reach any conclusion about the nature of the isotropic-nematic transition.

709.4206 | In silico network topology-based prediction of gene essentiality | The identification of genes essential for survival is important for the
understanding of the minimal requirements for cellular life and for drug
design. As experimental studies with the purpose of building a catalog of
essential genes for a given organism are time-consuming and laborious, a
computational approach which could predict gene essentiality with high accuracy
would be of great value. We present here a novel computational approach, called
NTPGE (Network Topology-based Prediction of Gene Essentiality), that relies on
network topology features of a gene to estimate its essentiality. The first
step of NTPGE is to construct the integrated molecular network for a given
organism comprising protein physical, metabolic and transcriptional regulation
interactions. The second step consists in training a decision tree-based
machine learning algorithm on known essential and non-essential genes of the
organism of interest, considering as learning attributes the network topology
information for each of these genes. Finally, the decision tree classifier
generated is applied to the set of genes of this organism to estimate
essentiality for each gene. We applied the NTPGE approach for discovering
essential genes in Escherichia coli and then assessed its performance.

709.4207 | Deep study of the fast bipolar outflows in pre-PNe from CO mm-wave line
emission | High spatial resolution images of PNe have shown their extremely complex
morphology. However, the circumstellar envelopes of their progenitors, the AGB
stars, are strikingly spherical. In order to understand the carving processes
leading to axisymmetric nebulae, we are carrying out a study of a large sample
of pre-PNe. Our emission model of the nebular molecular gas (12CO & 13CO) will
allow us to determine important physical parameters (mass, linear momentum,
kinetic energy) of the fast bipolar and slow spherical nebular components
separately. We will study in an innovative way the properties for each source
individually, and put our results in an evolutionary context with the help of
the data obtained by us and collected from the literature.

709.4208 | Analysis of Flash ADC Data With VERITAS | VERITAS employs a 12m segmented mirror and pixellated photomultiplier tube
camera to detect the brief pulse of Cherenkov radiation produced by the
extensive air shower initiated by a cosmic high-energy gamma ray. The VERITAS
data acquisition system consists of a 500 Mega-Sample-Per-Second custom-built
flash ADC system, which samples the Cherenkov light pulse every 2 nanoseconds.
The integrated charge in each flash ADC channel is proportional to the amount
of Cherenkov light incident on the corresponding photomultiplier tube. Accurate
reconstruction of the integrated charge is required for accurate energy
estimation and spectral reconstruction. A reliable calculation of the
integrated charge at low intensities can lead to a reduction in the energy
threshold of the system, and an increase in sensitivity. This paper
investigates and compares several approaches for evaluating the integrated
charge. The Cherenkov pulse timing information in the flash ADC readout has the
potential to assist in background rejection techniques. Various methods for

709.4209 | Information capacity of genetic regulatory elements | Changes in a cell's external or internal conditions are usually reflected in
the concentrations of the relevant transcription factors. These proteins in
turn modulate the expression levels of the genes under their control and
sometimes need to perform non-trivial computations that integrate several
inputs and affect multiple genes. At the same time, the activities of the
regulated genes would fluctuate even if the inputs were held fixed, as a
consequence of the intrinsic noise in the system, and such noise must
fundamentally limit the reliability of any genetic computation. Here we use
information theory to formalize the notion of information transmission in
simple genetic regulatory elements in the presence of physically realistic
noise sources. The dependence of this "channel capacity" on noise parameters,
cooperativity and cost of making signaling molecules is explored
systematically. We find that, at least in principle, capacities higher than one
bit should be achievable and that consequently genetic regulation is not
limited the use of binary, or "on-off", components.

709.421 | Influence of Zeeman splitting and thermally excited polaron states on
magneto-electrical and magneto-thermal properties of magnetoresistive
polycrystalline manganite La_{0.8}Sr_{0.2}MnO_3 | Some possible connection between spin and charge degrees of freedom in
magneto-resistive manganites is investigated through a thorough experimental
study of the magnetic (AC susceptibility and DC magnetization) and transport
(resistivity and thermal conductivity) properties. Measurements are reported in
the case of well characterized polycrystalline La_{0.8}Sr_{0.2}MnO_3 samples.
The experimental results suggest rather strong field-induced polarization
effects in our material, clearly indicating the presence of ordered FM regions
inside the semiconducting phase. Using an analytical expression which fits the
spontaneous DC magnetization, the temperature and magnetic field dependences of
both electrical resistivity and thermal conductivity data are found to be well
reproduced through a universal scenario based on two mechanisms: (i) a
magnetization dependent spin polaron hopping influenced by a Zeeman splitting
effect, and (ii) properly defined thermally excited polaron states which have
to be taken into account in order to correctly describe the behavior of the
less conducting region. Using the experimentally found values of the magnetic
and electron localization temperatures, we obtain L=0.5nm and m_p=3.2m_e for
estimates of the localization length (size of the spin polaron) and effective
polaron mass, respectively.

709.4211 | Chandra ACIS Survey of M33 (ChASeM33): A First Look | We present an overview of the Chandra ACIS Survey of M33 (ChASeM33): A Deep
Survey of the Nearest Face-on Spiral Galaxy. The 1.4 Ms survey covers the
galaxy out to $R \approx 18\arcmin (\approx 4$ kpc). These data provide the
most intensive, high spatial resolution assessment of the X-ray source
populations available for the confused inner regions of M33. Mosaic images of
the ChASeM33 observations show several hundred individual X-ray sources as well
as soft diffuse emission from the hot interstellar medium. Bright, extended
emission surrounds the nucleus and is also seen from the giant \hii regions NGC
604 and IC 131. Fainter extended emission and numerous individual sources
appear to trace the inner spiral structure. The initial source catalog, arising
from $\sim$~2/3 of the expected survey data, includes 394 sources significant
at the $3\sigma$ confidence level or greater, down to a limiting luminosity
(absorbed) of $\sim$1.6\ergs{35} (0.35 -- 8.0 keV). The hardness ratios of the
sources separate those with soft, thermal spectra such as supernova remnants
from those with hard, non-thermal spectra such as X-ray binaries and background
active galactic nuclei. Emission extended beyond the Chandra point spread
function is evident in 23 of the 394 sources. Cross-correlation of the ChASeM33
sources against previous catalogs of X-ray sources in M33 results in matches
for the vast majority of the brighter sources and shows 28 ChASeM33 sources
within 10\arcsec of supernova remnants identified by prior optical and radio
searches. This brings the total number of such associations to 31 out of 100
known supernova remnants in M33.

709.4212 | Exact diagonalization analysis of the Anderson-Hubbard model and
comparison to real-space self-consistent Hartree-Fock solutions | We have obtained the exact ground state wave functions of the
Anderson-Hubbard model for different electron fillings on a 4x4 lattice with
periodic boundary conditions - for 1/2 filling such ground states have roughly
166 million states. When compared to the uncorrelated ground states (Hubbard
interaction set to zero) we have found strong evidence of the very effective
screening of the charge homogeneities due to the Hubbard interaction. We have
successfully modelled these local charge densities using a non-interacting
model with a static screening of the impurity potentials. In addition, we have
compared such wave functions to self-consistent real-space unrestricted
Hartree-Fock solutions and have found that these approximate ground state wave
functions are remarkably successful at reproducing the local charge densities,

709.4214 | Destruction of first-order phase transition in a random-field Ising
model | The phase transitions that occur in an infinite-range-interaction Ising
ferromagnet in the presence of a double-Gaussian random magnetic field are
analyzed. Such random fields are defined as a superposition of two Gaussian
distributions, presenting the same width $\sigma$. Is is argued that this
distribution is more appropriate for a theoretical description of real systems
than its simpler particular cases, i.e., the bimodal ($\sigma=0$) and the
single Gaussian distributions. It is shown that a low-temperature first-order
phase transition may be destructed for increasing values of $\sigma$, similarly
to what happens in the compound $Fe_{x}Mg_{1-x}Cl_{2}$, whose
finite-temperature first-order phase transition is presumably destructed by an
increase in the field randomness.

709.4215 | Multiplicity one Theorems | In the local, characteristic 0, non archimedean case, we consider
distributions on GL(n+1) which are invariant under the adjoint action of GL(n).
We prove that such distributions are invariant by transposition. This implies
that an admissible irreducible representation of GL(n+1), when restricted to

709.4216 | Critical structure of the QCD medium | Fluctuations in the vicinity of a phase transition are important but
neglected in mean-field theory. In order to assess the influence of such
fluctuations on the critical endpoint and the size of the critical region in
the QCD phase diagram, a mean-field calculation of a two-flavor quark-meson
model is compared with a renormalization group approach. However, due to the
lack of confinement in this effective model the equation of state near the
chiral phase transition is still unrealistic. A first improvement of this model
can be achieved by coupling quark degrees of freedom to the Polyakov loop,
consequently incorporating certain aspects of confinement. The influence of
these modifications on the resulting phase diagram is discussed.

709.4217 | Weak measurement and control of entanglement generation | In this paper we show how weak joint measurement and local feedback can be
used to control entanglement generation between two qubits. To do this, we make
use of a decoherence free subspace (DFS). Weak measurement and feedback can be
used to drive the system into this subspace rapidly. Once within the subspace,
feedback can generate entanglement rapidly, or turn off entanglement generation
dynamically. We also consider, in the context of weak measurement, some of
differences between purification and generating entanglement.

709.4219 | Is the sky falling? Searching for stellar streams in the local Milky Way
disc in the CORAVEL and RAVE surveys | We have searched for in-falling stellar streams on to the local Milky Way
disc in the CORAVEL and RAVE surveys. The CORAVEL survey consists of local
dwarf stars (Nordstrom et al. Geneva-Copenhagen survey) and local Famaey et al.
giant stars. We select RAVE stars with radial velocities that are sensitive to
the Galactic vertical space velocity (Galactic latitude b < -45 deg). Kuiper
statistics have been employed to test the symmetry of the Galactic vertical
velocity distribution functions in these samples for evidence of a net vertical
flow that could be associated with a (tidal?) stream of stars with vertically
coherent kinematics. In contrast to the `Field of Streams' found in the outer
halo, we find that the local volumes of the solar neighbourhood sampled by the
CORAVEL dwarfs (complete within ~3 x 10^-4 kpc^3), CORAVEL giants (complete
within ~5 x 10^-2 kpc^3) and RAVE (5-15% complete within ~8 kpc^3) are devoid
of any vertically coherent streams containing hundreds of stars. This is
sufficiently sensitive to allow our RAVE sample to rule out the passing of the
tidal stream of the disrupting Sagittarius (Sgr) dwarf galaxy through the solar
neighbourhood. This agrees with the most recent determination of its orbit and
dissociates it from the Helmi et al. halo stream. Our constraints on the
absence of the Sgr stream near the Sun could prove a useful tool for
discriminating between Galactic potential models. The lack of a net vertical
flow through the solar neighbourhood in the CORAVEL giants and RAVE samples
argues against the Virgo overdensity crossing the disc near the Sun. There are
no vertical streams in the CORAVEL giants and RAVE samples with stellar
densities >1.6 x 10^4 and 1.5 x 10^3 stars kpc^-3 respectively and therefore no
evidence for locally enhanced dark matter.

709.422 | Non-thermal emission processes in massive binaries | In this paper, I present a general discussion of several astrophysical
processes likely to play a role in the production of non-thermal emission in
massive stars, with emphasis on massive binaries. Even though the discussion
will start in the radio domain where the non-thermal emission was first
detected, the census of physical processes involved in the non-thermal emission
from massive stars shows that many spectral domains are concerned, from the
radio to the very high energies.
First, the theoretical aspects of the non-thermal emission from early-type
stars will be addressed. The main topics that will be discussed are
respectively the physics of individual stellar winds and their interaction in
binary systems, the acceleration of relativistic electrons, the magnetic field
of massive stars, and finally the non-thermal emission processes relevant to
the case of massive stars. Second, this general qualitative discussion will be
followed by a more quantitative one, devoted to the most probable scenario
where non-thermal radio emitters are massive binaries. I will show how several
stellar, wind and orbital parameters can be combined in order to make some
semi-quantitative predictions on the high-energy counterpart to the non-thermal
emission detected in the radio domain.
These theoretical considerations will be followed by a census of results
obtained so far, and related to this topic... (see paper for full abstract)

annihilation | Precision studies of QCD at electron-positron colliders are based on
measurements of event shapes and jet rates. To match the high experimental
accuracy, theoretical predictions to next-to-next-to-leading order (NNLO) in
QCD are needed for a reliable interpretation of the data. We report the first
calculation of NNLO corrections O(alpha_s^3) to three-jet production and
related event shapes, and discuss their phenomenological impact.

709.4225 | The status of Quantum Geometry in the dynamical sector of Loop Quantum
Cosmology | This letter is motivated by the recent papers by Dittrich and Thiemann and,
respectively, by Rovelli discussing the status of Quantum Geometry in the
dynamical sector of Loop Quantum Gravity. Since the papers consider model
examples, we also study the issue in the case of an example, namely on the Loop
Quantum Cosmology model of space-isotropic universe. We derive the
Rovelli-Thiemann-Ditrich partial observables corresponding to the quantum
geometry operators of LQC in both Hilbert spaces: the kinematical one and,
respectively, the physical Hilbert space of solutions to the quantum
constraints. We find, that Quantum Geometry can be used to characterize the
physical solutions, and the operators of quantum geometry preserve many of
their kinematical properties.

709.4226 | Tent Spaces Associated with Semigroups of Operators | We study tent spaces on general measure spaces $(\Omega, \mu)$. We assume
that there exists a semigroup of positive operators on $L^p(\Omega, \mu)$
satisfying a monotone property but do not assume any geometric/metric structure
on $\Omega$. The semigroup plays the same role as integrals on cones and cubes
in Euclidean spaces. We then study BMO spaces on general measure spaces and get
an analogue of Fefferman's $H^1$-BMO duality theory. We also get a $H^1$-BMO
duality inequality without assuming the monotone property.

709.4227 | Scalar Particle Contribution to Higgs Production via Gluon Fusion at NLO | We consider the gluon fusion production cross section of a scalar Higgs boson
in models where fermion and scalar massive colored particles are present. We
report analytic expressions for the matrix elements of $gg\to Hg$, $q\bar{q}\to
Hg$, and $qg\to Hq$ processes completing the calculation of the NLO QCD
corrections in these extended scenarios. The formulas are written in a complete
general case, allowing a flexible use for different theoretical models.
Applications of our results to two different models are presented: i) a model
in which the SM Higgs sector is augmented by a weak doublet scalar in the
$SU(N_c)$ adjoint representation. ii) The MSSM, in the limit of neglecting the
gluino contribution to the cross section.

proximity of the non-fermi liquid phase affects the CDW phase, and show that
there is a region in the phase diagram where we get a CDW phase without a gap

prediction where the gap is proportional to the order parameter.

709.4232 | Q-manifolds and Mackenzie theory: an overview | This text is meant to be a brief overview of the topics announced in the
title and is based on my talk in Vienna (August/September 2007). It does not
contain new results (except probably for a remark concerning Q-manifold
homology, which I wish to elaborate elsewhere).
"Mackenzie theory" stands for the rich circle of notions that have been put
forward by Kirill Mackenzie (solo or in collaboration): double structures such
as double Lie groupoids and double Lie algebroids, Lie bialgebroids and their
doubles, nontrivial dualities for double and multiple vector bundles, etc.
"Q-manifolds" are (super)manifolds with a homological vector field, i.e., a
self-commuting odd vector field. They may have an extra Z-grading (called
weight) not necessarily linked with the Z_2-grading (parity). I discuss double
Lie algebroids (discovered by Mackenzie) and explain how this quite complicated
fundamental notion is equivalent to a very simple one if the language of
Q-manifolds is used. In particular, it shows how the two seemingly different
notions of a "Drinfeld double" of a Lie bialgebroid due to Mackenzie and
Roytenberg respectively, turn out to be the same thing if properly understood.

mackenzie solo or in collaboration double structures such as double lie groupoids and double lie algebroids lie bialgebroids and their doubles nontrivial dualities for double and multiple vector bundles etc qmanifolds are supermanifolds with a homological vector field ie a selfcommuting odd vector field they may have an extra zgrading called weight not necessarily linked with the z_2grading parity i discuss double lie algebroids discovered by mackenzie and explain how this quite complicated fundamental notion is equivalent to a very simple one if the language of qmanifolds is used in particular it shows how the two seemingly different notions of a drinfeld double of a lie bialgebroid due to mackenzie and roytenberg respectively turn out to be the same thing if properly understood

709.4233 | VEGAS, the VERITAS Gamma-ray Analysis Suite | VERITAS, the Very Energetic Radiation Imaging Telescope Array System, is an
array of four 12 m diameter imaging atmospheric Cherenkov telescopes for
gamma-ray astronomy above 100 GeV currently in operation in Arizona. The
VERITAS Collaboration has developed VEGAS, the VERITAS Gamma-ray Analysis
Suite, a data-analysis software package for the processing of single- and
multiple-telescope data produced by the array. The package consists of a core
of six stages as well as visualisation and diagnostic components. It has been
developed in C++ using modern objected-oriented design patterns to be highly
flexible, configurable and extendable. VEGAS utilises CERN's ROOT data-analysis
framework and runs on Linux and Mac OS X systems. The architecture and
structure of the VEGAS package will be described in detail while the data
analysis algorithms are described in additional papers.

709.4234 | Cosmological bounds on oscillating dark energy models | We study some cosmological constraints on the two phenomenological models of
oscillating dark energy. In these scenarios, the equation of state of dark
energy varies periodically and may provide a way to unify the early
acceleration (inflation) and the late time acceleration of the universe. These
models give also an effective way to tackle the so-called cosmic coincidence
problem. We examine observational constraints on this class of models from the
latest observational data including the \emph{gold} sample of 182 type Ia

| astro-ph | we study some cosmological constraints on the two phenomenological models of oscillating dark energy in these scenarios the equation of state of dark energy varies periodically and may provide a way to unify the early acceleration inflation and the late time acceleration of the universe these models give also an effective way to tackle the socalled cosmic coincidence problem we examine observational constraints on this class of models from the latest observational data including the emphgold sample of 182 type ia supernovae the cmb shift parameter r and the bao measurements from the sloan digital sky survey | [['we', 'study', 'some', 'cosmological', 'constraints', 'on', 'the', 'two', 'phenomenological', 'models', 'of', 'oscillating', 'dark', 'energy', 'in', 'these', 'scenarios', 'the', 'equation', 'of', 'state', 'of', 'dark', 'energy', 'varies', 'periodically', 'and', 'may', 'provide', 'a', 'way', 'to', 'unify', 'the', 'early', 'acceleration', 'inflation', 'and', 'the', 'late', 'time', 'acceleration', 'of', 'the', 'universe', 'these', 'models', 'give', 'also', 'an', 'effective', 'way', 'to', 'tackle', 'the', 'socalled', 'cosmic', 'coincidence', 'problem', 'we', 'examine', 'observational', 'constraints', 'on', 'this', 'class', 'of', 'models', 'from', 'the', 'latest', 'observational', 'data', 'including', 'the', 'emphgold', 'sample', 'of', '182', 'type', 'ia', 'supernovae', 'the', 'cmb', 'shift', 'parameter', 'r', 'and', 'the', 'bao', 'measurements', 'from', 'the', 'sloan', 'digital', 'sky', 'survey']] | [-0.1123828284596045, 0.08626837968558058, -0.08511691186193031, 0.12383491159704774, -0.16432139671110002, -0.08518812328711459, 0.02829313346367214, 0.3031146532577491, -0.27124978317015025, -0.3551258897773691, 0.07983196742434208, -0.29844945851598204, -0.011808429278202892, 0.23275686888811514, -0.00668621096064243, -0.014590374424515926, 0.03934924527234638, -0.03875317835679863, -0.046185057855105585, -0.29951910440421176, 0.33615922915014756, 0.10721478605710123, 0.24932315106114813, -0.04767929643546183, 0.07216164056024485, -0.10827098594805629, -0.12207679552285328, -0.035377591099474845, -0.24566215234232547, 0.059054074231679216, 0.17884988329620383, 0.19854890661717384, 0.2035914437758938, -0.4147632791052096, -0.25603326390252557, 0.1884017251143904, 0.15893232676959068, 0.15972941283367037, -0.07575166927525755, -0.2978994221109705, -0.0022800815358911593, -0.17949121334042745, -0.09144770685276113, 0.012103489014444892, -0.026062013266953763, 0.05198801423845448, -0.20940603425284637, 0.14170592423761263, -0.009542231416790602, -0.010817850407059352, -0.15228092241264188, -0.08867569304474619, 0.020138862566811216, 0.02408763760527999, 0.07376224040677867, 0.010903497435363759, 0.0897167430537724, -0.16523173687374698, -0.07099844110150312, 0.4056772706626924, -0.0834917319031221, -0.039596773972062724, 0.1427043242783276, -0.13715903653004735, -0.15642382001465896, 0.023606638168464845, 0.18761073871390874, 0.05578763652880935, -0.17806223591251932, 0.13058526641941273, 0.03823069669306278, 0.14542268941025296, 0.039686358101742786, 0.040490631196532664, 0.29824440642115996, 0.14465935590206502, 0.050785041274982935, 0.06249358299543563, -0.1549706488281258, -0.0303919066953444, -0.3598465488877954, -0.0712141169369528, -0.12746683481274193, 0.06973651381804771, -0.15414903641239736, -0.1486761863535443, 0.42350060627171676, 0.15641068882841772, 0.23201827216922238, 0.05160186944779047, 0.31844335836694415, 0.028166324407889593, 0.00788622065303252, -0.0013412716438436939, 0.302956363290954, 0.10239756841826991, 0.15793167377255626, -0.23580852963664023, 0.006145458025185718, 0.015791993040937122] |
