711.4708 | On the theory of resonances in non-relativistic QED and related models | We study the mathematical theory of quantum resonances in the standard model
of non-relativistic QED and in Nelson's model. In particular, we estimate the
survival probability of metastable states corresponding to quantum resonances
and relate the resonances to poles of an analytic continuation of matrix
elements of the resolvent of the quantum Hamiltonian.

711.4709 | Medium Modifcations of Mesons in Elementary Reactions and Heavy-Ion
Collisions | Experimental searches for modifications of vector mesons in the nuclear
medium are reviewed. Data on $\rho,\omega$ and $\Phi$ mesons are presented. The
results have been obtained in elementary reactions with proton and photon beams
as well as in heavy-ion collisions. Compared to the free particle properties,
the $\omega$ and $\Phi$ meson are found to drop in mass at normal nuclear
matter density by 9-14% and 3.5% whereas their widths are reported to increase
by factors of about 16 and 3.6, respectively. For the $\rho$ meson, conflicting
results on in-medium mass shifts and broadening have been published. The
experimental data are compared to recent model calculations.

711.471 | Effects of network topology on wealth distributions | We focus on the problem of how wealth is distributed among the units of a
networked economic system. We first review the empirical results documenting
that in many economies the wealth distribution is described by a combination of
log--normal and power--law behaviours. We then focus on the Bouchaud--M\'ezard
model of wealth exchange, describing an economy of interacting agents connected
through an exchange network. We report analytical and numerical results showing
that the system self--organises towards a stationary state whose associated
wealth distribution depends crucially on the underlying interaction network. In
particular we show that if the network displays a homogeneous density of links,
the wealth distribution displays either the log--normal or the power--law form.
This means that the first--order topological properties alone (such as the
scale--free property) are not enough to explain the emergence of the
empirically observed \emph{mixed} form of the wealth distribution. In order to
reproduce this nontrivial pattern, the network has to be heterogeneously
divided into regions with variable density of links. We show new results
detailing how this effect is related to the higher--order correlation
properties of the underlying network. In particular, we analyse assortativity
by degree and the pairwise wealth correlations, and discuss the effects that
these properties have on each other.

711.4711 | NNLO corrections to event shapes in $e^+e^-$ annihilation | We compute the next-to-next-to-leading order (NNLO) QCD corrections to the
six most important event shape variables related to three-particle final states
in electron-positron annihilation. The corrections are sizeable for all
variables, however their magnitude is substantially different for different
observables. We observe that the NNLO corrections yield a considerably better
agreement between theory and experimental data both in shape and normalisation
of the event shape distributions. The renormalisation scale dependence of the
theoretical prediction is substantially reduced compared to the previously
existing NLO results. Our results will allow a precise determination of the
strong coupling constant from event shape data collected at LEP.

711.4712 | Programmable discriminator of coherent states - experimental realization | The optical implementation of the recently proposed unambiguous
identification of coherent states is presented. Our system works as a
programmable discriminator between two, in general non-orthogonal weak coherent
states. The principle of operation lies in the interference of three light
beams - two program states and one unknown coherent state which can be equal to
whichever of the two program states. The experiment is based on fiber optics.
Its results confirm theoretical predictions and the experimental setup can be
straightforwardly extended for higher numbers of program states.

711.4714 | Effects due to Resonant and Continuum States on the Neutrino-Nucleus
Cross Section | Estimates of the neutrino-nucleus cross section, for the charged-current
process nu+208Pb-> e+208Bi, are presented. The nuclear structure calculations
have been performed by considering bound, resonant, and continuum states in the
single-particle basis used to construct correlated proton-particle neutron-hole
configurations. The observed features of the spectrum of 208Bi have been
reproduced, as accurately as possible, by diagonalizing a phenomenological
multipole-multipole interaction. Calculations of the cross section, for values
of q 200 $ MeV, were performed, and the dependence of the results upon the
choice of the residual proton-neutron interaction was investigated. It is found
that the inclusion of resonant states in the calculation of the nuclear wave
functions increases the neutrino-nucleus cross section, and that the
contribution of the continuum is negligible.

711.4716 | The Theory of Kairons | In relativistic quantum mechanics wave functions of particles satisfy field
equations that have initial data on a space--like hypersurface. We propose a
dual field theory of ``wavicles'' that have their initial data on a time--like
worldline. Propagation of such fields is superluminal, even though the Hilbert
space of the solutions carries a unitary representation of the Poincare group
of mass zero. We call the objects described by these field equations
``Kairons''. The paper builds the field equations in a general relativistic

level in mathematics but with no special knowledge on logic. The first
conference presents the formalization of mathematics with a short historical
survey, the language of first order predicates and the axioms of set theory.
The second and third lectures explain the incompleteness phenomena from the
Hilbert program until G\"odel's theorems with a presentation of the sequent
calculus of Gentzen.The fourth talk deepens model theory reasoning in the case
of the continuum hypothesis, and the last conference gives examples of
effective computability results.

711.4718 | Increase of Thermal Resistance Between a Nanostructure and a Surface due
to Phonon Multireflections | The thermal resistance between a nanostructure and a half-body is calculated
in the framework of particle-phonons physics. The current models approximate
the nanostructure as a thermal bath. We prove that the multireflections of heat
carriers in the nanostructure significantly increase resistance in
contradiction with former predictions. This increase depends on the shape of
the nanostructure and the heat carriers mean free path only. We provide a
general and simple expression for the contact resistance and examine the
specific cases of nanowires and nanoparticles.

711.4719 | Young stellar populations in the Magellanic Clouds | We discuss the young population of stars and clusters in the Magellanic
Clouds. We present the discovery of pre-main sequence candidates in the nebula
N~11 in the Large Magellanic Clouds using HST ACS photometry. The comparison of
the Colour-Magnitude diagram with pre-main sequence tracks and the presence of

711.4722 | The heavy-quark potential in an anisotropic plasma | We determine the hard-loop resummed propagator in an anisotropic QCD plasma
in general covariant gauges and define a potential between heavy quarks from
the Fourier transform of its static limit. We find that there is stronger

711.4724 | A viscoelastic deadly fluid in carnivorous pitcher plants | Background : The carnivorous plants of the genus Nepenthes, widely
distributed in the Asian tropics, rely mostly on nutrients derived from
arthropods trapped in their pitcher-shaped leaves and digested by their
enzymatic fluid. The genus exhibits a great diversity of prey and pitcher forms
and its mechanism of trapping has long intrigued scientists. The slippery inner
surfaces of the pitchers, which can be waxy or highly wettable, have so far
been considered as the key trapping devices. However, the occurrence of species
lacking such epidermal specializations but still effective at trapping insects
suggests the possible implication of other mechanisms. Methodology/Principal
Findings : Using a combination of insect bioassays, high-speed video and
rheological measurements, we show that the digestive fluid of Nepenthes
rafflesiana is highly viscoelastic and that this physical property is crucial
for the retention of insects in its traps. Trapping efficiency is shown to
remain strong even when the fluid is highly diluted by water, as long as the
elastic relaxation time of the fluid is higher than the typical time scale of
insect movements. Conclusions/Significance : This finding challenges the common
classification of Nepenthes pitchers as simple passive traps and is of great
adaptive significance for these tropical plants, which are often submitted to
high rainfalls and variations in fluid concentration. The viscoelastic trap
constitutes a cryptic but potentially widespread adaptation of Nepenthes
species and could be a homologous trait shared through common ancestry with the
sundew (Drosera) flypaper plants. Such large production of a highly
viscoelastic biopolymer fluid in permanent pools is nevertheless unique in the
plant kingdom and suggests novel applications for pest control.

711.4726 | Mean-field dynamo in a turbulence with shear and kinetic helicity
fluctuations | We study effects of kinetic helicity fluctuations in a turbulence with
large-scale shear using two different approaches: the spectral
tau-approximation and the second order correlation approximation (or
first-order smoothing approximation). These two approaches demonstrate that
homogeneous kinetic helicity fluctuations alone with zero mean value in a
sheared homogeneous turbulence cannot cause large-scale dynamo. Mean-field
dynamo can be possible when kinetic helicity fluctuations are inhomogeneous
which cause a nonzero mean alpha effect in a sheared turbulence. On the other
hand, shear-current effect can generate large-scale magnetic field even in a
homogeneous nonhelical turbulence with large-scale shear. This effect was
investigated previously for large hydrodynamic and magnetic Reynolds numbers.
In this study we examine the threshold required for the shear-current dynamo
versus Reynolds number. We demonstrate that there is no need for a developed
inertial range in order to maintain the shear-current dynamo (e.g., the
threshold in the Reynolds number is of the order of 1).

711.4727 | Third Family Corrections to Tri-bimaximal Lepton Mixing and a New Sum
Rule | We investigate the theoretical stability of the predictions of tri-bimaximal
neutrino mixing with respect to third family wave-function corrections. Such
third family wave-function corrections can arise from either the canonical
normalisation of the kinetic terms or renormalisation group running effects. At
leading order both sorts of corrections can be subsumed into a single universal
parameter. For hierarchical neutrinos, this leads to a new testable lepton
mixing sum rule 's = r cos delta + 2/3 a' (where s, r, a describe the
deviations of solar, reactor and atmospheric mixing angles from their
tri-bimaximal values, and 'delta' is the observable Dirac CP phase) which is

711.4729 | Bogoliubov theory of quantum correlations in the time-dependent
Bose-Hubbard model | By means of an adapted mean-field expansion for large fillings $n\gg1$, we
study the evolution of quantum fluctuations in the time-dependent Bose-Hubbard
model, starting in the superfluid state and approaching the Mott phase by
decreasing the tunneling rate or increasing the interaction strength in time.
For experimentally relevant cases, we derive analytical results for the
temporal behavior of the number and phase fluctuations, respectively. This
allows us to calculate the growth of the quantum depletion and the decay of
off-diagonal long-range order. We estimate the conditions for the observability
of the time dependence in the correlation functions in the experimental setups
with external trapping present. Finally, we discuss the analogy to quantum
effects in the early universe during the inflationary epoch.

711.4731 | Competing Orders in One-Dimensional Half-Integer Fermionic Cold Atoms: A
Conformal Field Theory Approach | The physical properties of arbitrary half-integer spins F = N - 1/2 fermionic
cold atoms loaded into a one-dimensional optical lattice are investigated by
means of a conformal field theory approach. We show that for attractive
interactions two different superfluid phases emerge for F \ge 3/2: A BCS
pairing phase, and a molecular superfluid phase which is formed from
bound-states made of 2N fermions. In the low-energy approach, the competition
between these instabilities and charge-density waves is described in terms of
Z_N parafermionic degrees of freedom. The quantum phase transition for
F=3/2,5/2 is universal and shown to belong to the Ising and three-state Potts
universality classes respectively. For a filling of one atom per site, a Mott
transition occurs and the nature of the possible Mott-insulating phases are
determined.

711.4732 | Spherical symmetric charged solution with cosmological constant | A spherically symmetric charged ideal fluid solution of Einstein field
equation is given in the presence of the cosmological constant and two well
known example of this type of solution is presented. If the matter is confined
in a region, the exterior spacetime is considered as RN-de Sitter
(Reissner-Nordstrom de Sitter) and to complete solution matching conditions are
examined. We show that the function which is related to the dynamics of the
system will determine the fate of the system: expansion, contraction or
bouncing situations may occur for different configurations. The initial
conditions of the matter determine the final form of the system and therefore
the nature of the singularities in the presence of the electric charge and the

711.4733 | A Coupled Oscillator Model for Grover's Quantum Database Search
Algorithm | Grover's database search algorithm is the optimal algorithm for finding a
desired object from an unsorted collection of items. Although it was discovered
in the context of quantum computation, it is simple and versatile enough to be
implemented using any physical system that allows superposition of states, and
several proposals have been made in the literature. I study a mechanical
realisation of the algorithm using coupled simple harmonic oscillators, and
construct its physical model for the simplest case of four identical
oscillators. The identification oracle is implemented as an elastic reflection
of the desired oscillator, and the overrelaxation operation is realised as
evolution of the system by half an oscillation period. I derive the equations
of motion, and solve them both analytically and by computer simulation. I
extend the ideal case analysis and explore the sensitivity of the algorithm to
changes in the initial conditions, masses of springs and damping. The amplitude
amplification provided by the algorithm enhances the energy of the desired
oscillator, while running the algorithm backwards spreads out the energy of the
perturbed oscillator among its partners. The former (efficient focusing of
energy into a specific oscillator) can have interesting applications in
processes that need crossing of an energy threshold for completion, and can be
useful in nanotechnological devices and catalysis. The latter (efficient
redistribution of energy) can be useful in processes requiring rapid
dissipation of energy, such as shock-absorbers and vibrational shielding. I
present some tentative proposals.

711.4734 | Signed Chord Length Distribution. I | In this paper is discussed an application of signed measures (charges) to
description of segment and chord length distributions in nonconvex bodies. The
signed distribution may naturally appears due to definition via derivatives of
nonnegative autocorrelation function simply related with distances distribution
between pairs of points in the body. In the work is suggested constructive
geometrical interpretation of such derivatives and illustrated appearance of
"positive" and "negative" elements similar with usual Hanh-Jordan decomposition

711.4735 | Recovering the stationary phase condition for accurately obtaining
scattering and tunneling times | The stationary phase method is often employed for computing tunneling {\em
phase} times of analytically-continuous {\em gaussian} or infinite-bandwidth
step pulses which collide with a potential barrier. The indiscriminate
utilization of this method without considering the barrier boundary effects
leads to some misconceptions in the interpretation of the phase times. After
reexamining the above barrier diffusion problem where we notice the wave packet
collision necessarily leads to the possibility of multiple reflected and
transmitted wave packets, we study the phase times for tunneling/reflecting
particles in a framework where an idea of multiple wave packet decomposition is
recovered. To partially overcome the analytical incongruities which rise up
when tunneling phase time expressions are obtained, we present a theoretical
exercise involving a symmetrical collision between two identical wave packets
and a one dimensional squared potential barrier where the scattered wave
packets can be recomposed by summing the amplitudes of simultaneously reflected
and transmitted waves.

711.4736 | Beam spin asymmetry in deep and exclusive pi0 electroproduction | The beam spin asymmetry (BSA) in the exclusive reaction ep->ep pi0 was
measured with the CEBAF 5.77 GeV polarized electron beam and Large Acceptance
Spectrometer(CLAS). The xB, Q2, t and phi dependences of the pi0 BSA are
presented in the deep inelastic regime. The asymmetries are fitted with a
sin(phi) function and their amplitudes are extracted. Overall, they are of the
order of 0.04 - 0.11 and roughly independent of t. This is the signature of a
non-zero longitudinal-transverse interference. The implications concerning the
applicability of a formalism based on generalized parton distributions, as well

711.4737 | Observation of free hole gases at ambient conditions | By studying fluctuations in the electrostatic potential of a single electrode
immersed in a cold plasma, we were able to perform in situ electron
spectroscopy. Electron exchange processes that occur at the surface of the
electrode were triggered by the surface Auger process either using metastable
molecular nitrogen or triplet helium at ambient conditions. Ongoing redox
reactions were decomposed into their two fundamental half reactions and the
reduction and oxidation potentials were detected. We found that redox reactions
near the electrode surface are the result of binary interactions of a free
electron gas with a free hole gas that occur on a femtosecond time scale. The
measured lifetimes of electron-hole recombination processes and the elastic
scattering rate of the hole-hole process are in fair agreement with theoretical
estimates. The observed asymmetry in the energy distributions of free electron
and free hole ensembles suggests that at thermal equilibrium the identity of
hole differs from that of an electron vacancy.

711.4738 | Interpreting the Quantum Wave Function in Terms of 'Interacting
Faculties' | In this article we discuss the problem of finding an interpretation of
quantum mechanics which provides an objective account of physical reality. In
the first place we discuss the problem of interpretation and analyze the
importance of such an objective account in physics. In this context we present
the problems which arise when interpreting the quantum wave function within the
orthodox formulation of quantum mechanics. In connection to this critic, we
expose the concept of 'entity' as an epistemological obstruction.
In the second part of this paper we discuss the relation between actuality
and potentiality in classical and quantum physics, and continue to present the
concept of 'ontological potentiality' which is distinguished from the generic
Aristotelian notion of potentiality in terms of 'becoming actual'. In this
paper our main aim is to provide an objective interpretation of quantum
mechanics which allows us to discuss the meaning of physical reality according
to the theory. For this specific propose we present the concept of 'faculty' in
place of the concept of 'entity'. Within our theory of faculties, we continue
to discuss and interpret two paradigmatic experiments of quantum mechanics such
as the double-slit and Schrodinger's cat.

711.4741 | The Jlab Upgrade - Studies of the Nucleon with CLAS12 | An overview is presented on the program to study the nucleon structure at the
12 GeV JLab upgrade using the CLAS12 detector. The focus is on deeply virtual
exclusive processes to access the generalized parton distributions,
semni-inclusive processes to study transverse momentum dependent distribution

711.4742 | Magnetoelastic and thermal effects in the BiMn2O5 lattice: a
high-resolution x-ray diffraction study | High-resolution synchrotron x-ray diffraction measurements were performed on
single crystalline and powder samples of BiMn2O5. A linear temperature
dependence of the unit cell volume was found between T_{N}=38$ K and 100 K,
suggesting that a low-energy lattice excitation may be responsible for the
lattice expansion in this temperature range. Between T* ~ 65 K and T_{N}, all
lattice parameters showed incipient magnetoelastic effects, due to short-range
spin correlations. An anisotropic strain along the a-direction was also
observed below T*. Below T_{N}, a relatively large contraction of the
a-parameter following the square of the average sublattice magnetization of Mn
was found, indicating that a second-order spin hamiltonian accounts for the
magnetic interactions along this direction. On the other hand, the more complex
behaviors found for $b$ and $c$ suggest additional magnetic transitions below
T_{N} and perhaps higher-order terms in the spin hamiltonian. Polycrystalline
samples grown by distinct routes and with nearly homogeneous crystal structure
above T_{N} presented structural phase coexistence below T_{N}, indicating a
close competition amongst distinct magnetostructural states in this compound.

711.4743 | Cell-permeable tumor suppressor peptides for cancer therapy: back to the
future | Miniaturization is a hallmark of modern technologies. Notably, this feature
has not spared molecular biology and its potential applications. Towards
developing more effective therapeutics against cancer, studies began to explore
more than a decade ago how natural tumor suppression could be translated into
antineoplastic drugs. To this end, investigators focused on major constituents
of a central pathway that protects cells against neoplastic transformation: the
nuclear retinoblastoma protein (RB) pathway. As such, peptide mimetics of RB,
p16 and p21 were developed. Likewise, the p53 and von Hippel-Lindau gene
products which affect indirectly the RB pathway provided additional templates
for the development of anti-proliferative peptides. Each of the peptides
derived from these distinct tumor suppressors was made cell-permeable by its
ligation to an amino acid sequence conferring cellular internalization. Details
reviewed here reveal that through the application of such anti-cancer peptide

711.4744 | On the question of ferromagnetism in alkali metal thin films | Electronic and magnetic structure of $(100)$ films of K and Cs are calculated
within the plane-wave projector augmented wave (PAW) formalism of the density
functional theory (DFT) using both local spin density approximation (LSDA) and
the PW91 generalized gradient approximation (GGA). Only a 6 layer Cs film is
found to have a ferromagnetic (FM) state which is degenerate with a
paramagnetic (PM) state within the accuracy of these calculations. This is at
variance with the results obtained from a finite thickness uniform jellium
model (UJM). Implications of these results for the experiments on transition
metal doped alkali metal thin films and bulk hosts are discussed.

711.4745 | Networking Behavior in Thin Film and Nanostructure Growth Dynamics | Thin film coatings have been essential in development of several micro and
nano-scale devices. To realize thin film coatings various deposition techniques
are employed, each yielding surface morphologies with different characteristics
of interest. Therefore, understanding and control of the surface growth is of
great interest. In this paper, we devise a novel network-based modeling of the
growth dynamics of such thin films and nano-structures. We specifically map
dynamic steps taking place during the growth to components (e.g., nodes, links)
of a corresponding network. We present initial results showing that this
network-based modeling approach to the growth dynamics can simplify our

711.4746 | Electron interactions in an antidot in the integer quantum Hall regime | A quantum antidot, a submicron depletion region in a two-dimensional electron
system, has been actively studied in the past two decades, providing a powerful
tool for understanding quantum Hall systems. In a perpendicular magnetic field,
electrons form bound states around the antidot. Aharonov-Bohm resonances
through such bound states have been experimentally studied, showing interesting
phenomena such as Coulomb charging, h/2e oscillations, spectator modes,
signatures of electron interactions in the line shape, Kondo effect, etc. None
of them can be explained by a simple noninteracting electron approach.
Theoretical models for the above observations have been developed recently,
such as a capacitive-interaction model for explaining the h/2e oscillations and
the Kondo effect, numerical prediction of a hole maximum-density-droplet
antidot ground state, and spin density-functional theory for investigating the
compressibility of antidot edges. In this review, we summarize such
experimental and theoretical works on electron interactions in antidots.

in the energy range 1200--1800 MeV, there are three rho-like mesons: rho(1250),
rho(1450) and rho(1600), unlike the PDG tables. The obtained P-wave pion-pion

711.475 | Microlensing search for extrasolar planets: observational strategy,
discoveries and implications | Microlensing has proven to be a valuable tool to search for extrasolar
planets of Jovian- to Super-Earth-mass planets at orbits of a few AU. Since
planetary signals are of very short duration, an intense and continuous
monitoring is required. This is achieved by ground-based networks of telescopes
(PLANET/RoboNET, microFUN) following up targets, which are identified as
microlensing events by single dedicated telescopes (OGLE, MOA). Microlensing
has led to four already published detections of extrasolar planets, one of them
being OGLE-2005-BLG-390Lb, a planet of only ~5.5 M_earth orbiting its M-dwarf
host star at ~2.6 AU. Very recent observations (May--September 2007) provided
more planetary candidates, still under study, that will double the number of
detections. For non-planetary microlensing events observed from 1995 to 2006 we
compute detection efficiency diagrams, which can then be used to derive an

711.4752 | Causal Relationships between Eruptive Prominences and Coronal Mass
Ejections | A close association between eruptive prominences and CMEs, both slow and fast
CMEs, was reported in many studies. Sometimes it is possible to follow the
material motion starting from the prominence (filament) activation to the CME
in the high corona. Remnants of the prominence were found in the bright core of
CMEs. However, detailed comparisons of the two phenomena reveal problems in
explaining CMEs as a continuation of filament eruptions in the upper corona.
For example, the heliolatitudes of the disappeared filaments and subsequent
coronal ejections sometimes differ by tens of degrees. In order to clear up the
problems of EP-CME association we tentatively analyse the more general question
of the dynamics of a magnetic flux rope. Prominences and filaments are the best
tracers of the flux ropes in the corona long before the beginning of the
eruption. A twisted flux rope is held by the tension of field lines of
photospheric sources until parameters of the system reach critical values and a
catastrophe happens. We suggest that the associated flux rope height above the
photosphere is one of these parameters and it is revealed by the height of the
filament. 80 filaments were analysed and we found that eruptive prominences
were near the so-called limit of stability a few days before their eruptions.
We suggest that a comparison of the real heights of prominences with the
calculated critical heights from magnetograms could be systematically used to
predict filament eruptions and the corresponding CMEs.

711.4753 | Blowup of Jang's equation at outermost marginally trapped surfaces | The aim of this paper is to collect some facts about the blowup of Jang's
equation. First, we discuss how to construct solutions that blow up at an
outermost MOTS. Second, we exclude the possibility that there are extra blowup
surfaces in data sets with non-positive mean curvature. Then we investigate the
rate of convergence of the blowup to a cylinder near a strictly stable MOTS and
show exponential convergence near a strictly stable MOTS.

in the theory can give rise to effective operators with different Lorentz

easily understood. The unique feature of a complex phase in the propagator of
the unparticle can also be understood uniquely for the different spins by
exploiting the initial beam polarizations at the International Linear Collider

711.4755 | Band structure related wave function symmetry of amphoteric Si dopants
in GaAs | Autocompensated Si-doped GaAs is studied with cross-sectional scanning
tunneling spectroscopy (X-STS). The local electronic contrasts of
substitutional Si(Ga) donors and Si(As) acceptors under the (110) cleavage
plane are imaged with high resolution. Si(Ga) donor atoms exhibit radially
symmetric contrasts. Si(As) acceptors have anisotropic features. The
anisotropic acceptor contrasts are traced back to a tunnel process at the

711.4757 | The cool supergiant population of the massive young star cluster RSGC1 | We present new high-resolution near-IR spectroscopy and OH maser observations
to investigate the population of cool luminous stars of the young massive
Galactic cluster RSGC1. Using the 2.293\micron CO-bandhead feature, we make
high-precision radial velocity measurements of 16 of the 17 candidate Red
Supergiants (RSGs) identified by Figer et al. We show that F16 and F17 are
foreground stars, while we confirm that the rest are indeed
physically-associated RSGs. We determine that Star F15, also associated with
the cluster, is a Yellow Hypergiant based on its luminosity and spectroscopic
similarity to $\rho$ Cas. Using the cluster's radial velocity, we have derived
the kinematic distance to the cluster and revisited the stars' temperatures and
luminosities. We find a larger spread of luminosities than in the discovery
paper, consistent with a cluster age 30% older than previously thought
(12$\pm$2Myr), and a total initial mass of $(3\pm1) \times 10^{4}$\msun. The
spatial coincidence of the OH maser with F13, combined with similar radial
velocities, is compelling evidence that the two are related. Combining our
results with recent SiO and H$_2$O maser observations, we find that those stars
with maser emission are the most luminous in the cluster. From this we suggest
that the maser-active phase is associated with the end of the RSG stage, when
the luminosity-mass ratios are at their highest.

711.4758 | Generalized Galitskii approach for the vertex function of a Fermi gas
with resonant interaction | We present a generalized Galitskii approach for the Bethe-Salpeter equation
for the two-particle vertex function of a Fermi system with resonant
interaction by accounting for the resonant state in the scattering potential
and utilizing the universal form of the resonant scattering amplitude. The
procedure can be carried out both for the normal as well as for the condensate
state. In both cases, the vertex function in the vicinity of the resonance is
shown to formally coincide with that obtained for a weakly attractive Fermi
gas. Thus we justify the popular calculational framework in which results for
the weakly attractive Fermi gas are formally extrapolated into the domain of
strong coupling, and further to the repulsive side of the resonance, where
molecular states are formed.

711.4759 | Copeland Voting Fully Resists Constructive Control | Control and bribery are settings in which an external agent seeks to
influence the outcome of an election. Faliszewski et al. [FHHR07] proved that
Llull voting (which is here denoted by Copeland^1) and a variant (here denoted
by Copeland^0) of Copeland voting are computationally resistant to many, yet
not all, types of constructive control and that they also provide broad
resistance to bribery. We study a parameterized version of Copeland voting,
denoted by Copeland^alpha where the parameter alpha is a rational number
between 0 and 1 that specifies how ties are valued in the pairwise comparisons
of candidates in Copeland elections. We establish resistance or vulnerability
results, in every previously studied control scenario, for Copeland^alpha, for
each rational alpha, 0 <alpha < 1. In particular, we prove that Copeland^0.5,
the system commonly referred to as ``Copeland voting,'' provides full
resistance to constructive control. Among the systems with a polynomial-time
winner problem, this is the first natural election system proven to have full
resistance to constructive control. Results on bribery and fixed-parameter
tractability of bounded-case control proven for Copeland^0 and Copeland^1 in
[FHHR07] are extended to Copeland^alpha for each rational alpha, 0 < alpha < 1;
we also give results in more flexible models such as microbribery and extended
control.

711.476 | VLTI/MIDI Observations of the Massive Protostellar Candidate NGC 3603
IRS 9A | We used MIDI, the mid-infrared interferometric instrument of the VLTI, to
observe the massive protostellar candidate IRS 9A, located at a distance of
about 7 kpc at the periphery of the NGC 3603 star cluster. Our ongoing analysis
shows that MIDI almost fully resolves the object on all observed baselines, yet
below 9 $\mu$m we detect a steep rise of the visibility. This feature is
modelled as a combination of a compact hot component and a resolved warm
envelope which lowers the correlated flux at longer wavelengths. The extended
envelope can already be seen in both MIDI's acquisition images and in
complementary data from aperture masking observations at the Gemini South
telescope. Its shape is asymmetric, which could indicate a circumstellar disk
inclined against the line of sight. The compact component is possibly related
to the inner edge of this (accretion) disk. The uncorrelated mid-infrared

711.4761 | Path-Integral Renormalization Group Treatments for Many-Electron Systems
with Long-Range Repulsive Interactions | A practical algorithm for many-electron systems based on the path-integral
renormalization group (PIRG) method is proposed in the real-space
finite-difference (RSFD) approach. The PIRG method, developed for investigating
strongly correlated electron systems, has been successfully applied to some
models such as Hubbard models. However, to apply this method to more realistic
systems of electrons with long-range Coulomb interactions within the RSFD
formalism, the one-body Green's function, which requires large computational
resources, is to be replaced with an alternative. For the same reason, an
efficient algorithm for computing the Fock matrix is needed. The newly proposed
algorithm is free of the one-body Green's function and enables us to compute
the Fock matrix efficiently. Our result shows a significant reduction in CPU
time and the possibility of using the present algorithm as a practical
numerical tool.

711.4763 | Calculation of the Two-body T-matrix in Configuration Space | A spectral integral method (IEM) for solving the two-body Schroedinger
equation in configuration space is generalized to the calculation of the
corresponding T-matrix. It is found that the desirable features of the IEM,
such as the economy of mesh-points for a given required accuracy, are carried
over also to the solution of the T-matrix. However the algorithm is
considerably more complex, because the T-matrix is a function of two variables
r and r', rather than only one variable r, and has a slope discontinuity at

is achieved, with the number N of Chebyshev support points in each partition
equal to 17. For a potential with a large repulsive core, such as the potential
between two He atoms, the accuracy decreases to 4 significant figures, but is
restored to 7 if N is increased to 65.

711.4765 | The underscreened Kondo lattice model applied to heavy fermion uranium
compounds | We present theoretical results for the underscreened Kondo lattice model with
localized S=1 spins coupled to a conduction band through a Kondo coupling,
$J_K$, and interacting among them ferromagnetically. We use a fermionic
representation for the spin operators and expand the Hamiltonian in terms of
bosonic fields. For large values of $J_K$, we obtain a ferromagnetically
ordered solution and a Kondo regime with a Kondo temperature, $T_K$, larger
than the Curie temperature, $T_C$. This finding suggests a scenario for a
coexistence of Kondo effect and ferromagnetic order. In some uranium compounds,
like $UTe$ or $UCu_{0.9}Sb_{2}$, this kind of coexistence has been
experimentally observed: they order ferromagnetically with a Curie temperature
of order $T_C \sim 100K$ and exhibit a Kondo behavior for $T > T_C$. The
proposed underscreened Kondo lattice model accounts well for the coexistence

711.4768 | Tongue Liminary Threshold Identification to Electrotactile Stimulation | Many applications use electrostimulation of the human skin to provide tactile
sensation. The effect of electrotactile stimulations were studied on a 6x6
matrix of tactile electrodes placed on the anterior part of the tongue. The
liminary threshold with continuous or discontinuous waveform and patterns with
2 or 4 electrodes was investigated. The result suggest that for energy saving

711.477 | Exponential complexity and ontological theories of quantum mechanics | Ontological theories of quantum mechanics describe a single system by means
of well-defined classical variables and attribute the quantum uncertainties to
our ignorance about the underlying reality represented by these variables. We
consider the general class of ontological theories describing a quantum system
by a set of variables with Markovian (either deterministic or stochastic)
evolution. We provide the first proof that the number of continuous variables
can not be smaller than 2N-2, N being the Hilbert space dimension. Thus, any
ontological Markovian theory of quantum mechanics requires a number of
variables which grows exponentially with the physical size. This result is
relevant also in the framework of quantum Monte Carlo methods.

711.4771 | Sequestered uplifting and the pattern of soft supersymmetry breaking
terms | We examine the pattern of soft supersymmetry breaking terms in moduli
stabilization, where an uplifting potential is provided by spontaneously broken
supersymmetry in a generic sequestered sector. From stationary conditions, we
derive the relation between moduli F-term vacuum expectation values which does

as a model of short-term variability of active galactic nuclei. In this paper
we apply the theory of random point processes to model the observed signal from
an ensemble of randomly generated spots. The influence of general relativistic
effects near a black hole is taken into account and it is shown that typical
features of power spectral density can be reproduced. Connection among spots is
also discussed in terms of Hawkes' process, which produces more power at low
frequencies. We derive a semi-analytical way to approximate the resulting
power-spectral density.

711.4773 | The polyhedral nature of LINERs: An XMM-Newton view of LINERs in radio
galaxies | Aims: We investigate the origin of X-rays and the nature of accretion flow in
4 LINERs hosted by radio galaxies, namely NGC1692, PKS0625-35, 3C88, 3C444,
recently observed with XMM. Methods: We combine the results from the
time-averaged spectral analysis with model-independent information from X-ray
temporal and spectral variability analyses, and with additional broadband
information (UV and radio). Results: The values of the Eddington ratios of our
sample span 2 orders of magnitude. The 4 AGN are adequately fitted by the same
continuum model that comprises at least one thermal component and a partially
absorbed power law, whose relative contribution and photon index vary
substantially from source to source. NGC1692 and PKS0625-35 have fairly steep
power-law components, perhaps indicative of synchrotron emission from a jet.
Conversely, the flat photon index derived for 3C88 may be indicative of a
heavily absorbed object. Finally, the time-averaged spectral properties of
3C444 (Gamma~1.9 and an apparent line-like excess around 6.7 keV) are more in
line with Seyfert galaxies. The temporal analysis reveals that PKS0625-35 and
3C88 are significantly variable in the soft energy band. PKS0625-35 also shows
suggestive evidence of spectral variability on timescales of months. The main
findings from the broadband analysis can be summarized as follows: 1) 3C444,
PKS0625-35, and NGC1692 have alpha_OX values consistent with the well known
alpha_OX -l_UV correlation. 2) No positive correlation is found between L_X and
the inclination angle, suggesting that the X-ray emission is not beamed. 3) The
values of the radio-loudness are inversely proportional to the Eddington ratio
and locate our objects in between the ``radio-loud'' and ``radio-quiet''
branches in the R- l_UV plane.

711.4775 | The window at the edge of chaos in a simple model of gene interaction
networks | As a model for gene and protein interactions we study a set for molecular
catalytic reactions. The model is based on experimentally motivated interaction
network topologies, and is designed to capture some key statistics of gene
expression statistics. We impose a non-linearity to the system by a boundary
condition which guarantees non-negative concentrations of chemical
concentrations and study the system stability quantified by maximum Lyapunov
exponents. We find that the non-negativity constraint leads to a drastic
inflation of those regions in parameter space where the Lyapunov exponent
exactly vanishes. We explain the finding as a self-organized critical
phenomenon. The robustness of this finding with respect to different network
topologies and the role of intrinsic molecular- and external noise is
discussed. We argue that systems with inflated 'edges of chaos' could be much
more easily favored by natural selection than systems where the Lyapunov
exponent vanishes only on a parameter set of measure zero.

711.4776 | Magnetoelectric Effects on Composite Nano Granular $Fe/TiO_{2-\delta}$
Films | Employing a new experimental technique to measure magnetoelectric response
functions, we have measured the magnetoelectric effect in composite films of
nano granular metallic iron in anatase titanium dioxide at temperatures below
50 K. A magnetoelectric resistance is defined as the ratio of a transverse
voltage to bias current as a function of the magnetic field. In contrast to the
anomalous Hall resistance measured above 50 K, the magnetoelectic resistance
below 50 K is significantly larger and exhibits an even symmetry with respect
to magnetic field reversal $H\to -H$. The measurement technique required
attached electrodes in the plane of the film composite in order to measure
voltage as a function of bias current and external magnetic field. To our
knowledge, the composite films are unique in terms of showing magnetoelectric

P = 0.5 y, with maxima in March and September. A daemon flux f ~ 10^-7 - 10^-6
cm^-2 s^-1 is capable of accounting for the Troitsk anomaly in the tritium
beta-spectrum and suggests its more pronounced manifestation in future KATRIN
experiment. In view of the channeling effect on iodine recoil nuclei in the
NaI(Tl) crystal, the DAMA/NaI experiment is also apparently detecting a flux of
daemons, f ~ 6x10^-7 cm^-2 s^-1, but in this case of those falling with V =
30-50 km/s from strongly elongated, Earth-crossing heliocentric orbits oriented
in the antapex direction, as a result of which the number of events detected in
the 2-6-keV interval varies with P = 1 y.

711.478 | Mosaic length and finite interaction-range effects in a one dimensional
random energy model | In this paper we study finite interaction range corrections to the mosaic
picture of the glass transition as emerges from the study of the Kac limit of
large interaction range for disordered models. To this aim we consider point to
set correlation functions, or overlaps, in a one dimensional random energy
model as a function of the range of interaction. In the Kac limit, the mosaic
length defines a sharp first order transition separating a high overlap phase
from a low overlap one. Correspondingly we find that overlap curves as a
function of the window size and different finite interaction ranges cross
roughly at the mosaic lenght. Nonetheless we find very slow convergence to the
Kac limit and we discuss why this could be a problem for measuring the mosaic
lenght in realistic models.

711.4782 | The Peculiar Type Ib Supernova 2006jc: A WCO Wolf-Rayet Star Explosion | We present a theoretical model for Type Ib supernova (SN) 2006jc. We
calculate the evolution of the progenitor star, hydrodynamics and
nucleosynthesis of the SN explosion, and the SN bolometric light curve (LC).
The synthetic bolometric LC is compared with the observed bolometric LC
constructed by integrating the UV, optical, near-infrared (NIR), and
mid-infrared (MIR) fluxes. The progenitor is assumed to be as massive as
$40M_\odot$ on the zero-age main-sequence. The star undergoes extensive mass
loss to reduce its mass down to as small as $6.9M_\odot$, thus becoming a WCO
Wolf-Rayet star. The WCO star model has a thick carbon-rich layer, in which
amorphous carbon grains can be formed. This could explain the NIR brightening
and the dust feature seen in the MIR spectrum. We suggest that the progenitor
of SN 2006jc is a WCO Wolf-Rayet star having undergone strong mass loss and
such massive stars are the important sites of dust formation. We derive the
parameters of the explosion model in order to reproduce the bolometric LC of SN
2006jc by the radioactive decays: the ejecta mass $4.9M_\odot$, hypernova-like
explosion energy $10^{52}$ ergs, and ejected $^{56}$Ni mass $0.22M_\odot$. We
also calculate the circumstellar interaction and find that a CSM with a flat
density structure is required to reproduce the X-ray LC of SN 2006jc. This
suggests a drastic change of the mass-loss rate and/or the wind velocity that
is consistent with the past luminous blue variable (LBV)-like event.

711.4784 | Transport reversal in a delayed feedback ratchet | Feedback flashing ratchets are thermal rectifiers that use information on the
state of the system to operate the switching on and off of a periodic
potential. They can induce directed transport even with symmetric potentials
thanks to the asymmetry of the feedback protocol. We investigate here the
dynamics of a feedback flashing ratchet when the asymmetry of the ratchet
potential and of the feedback protocol favor transport in opposite directions.
The introduction of a time delay in the control strategy allows one to
nontrivially tune the relative relevance of the competing asymmetries leading
to an interesting dynamics. We show that the competition between the
asymmetries leads to a current reversal for large delays. For small ensembles
of particles current reversal appears as the consequence of the emergence of an
open-loop like dynamical regime, while for large ensembles of particles it can
be understood as a consequence of the stabilization of quasiperiodic solutions.
We also comment on the experimental feasibility of these feedback ratchets and
their potential applications.

711.4785 | Deuteron form factors in chiral effective theory: regulator-independent
results and the role of two-pion exchange | We evaluate the deuteron charge, quadrupole, and magnetic form factors using
wave functions obtained from chiral effective theory ($\chi$ET) when the
potential includes one-pion exchange, chiral two-pion exchange, and genuine
contact interactions. We study the manner in which the results for form factors
behave as the regulator is removed from the $\chi$ET calculation, and compare
co-ordinate- and momentum-space approaches. We show that, for both the LO and
NNLO chiral potential, results obtained by imposing boundary conditions in
co-ordinate space at $r=0$ are equivalent to the $\Lambda \to \infty$ limit of
momentum-space calculations. The regulator-independent predictions for deuteron
form factors that result from taking the $\Lambda \to \infty$ limit using the
LO $\chi$ET potential are in reasonable agreement with data up to momentum
transfers of order 600 MeV, provided that phenomenological information for
nucleon structure is employed. In this range the use of the NNLO $\chi$ET

711.4786 | Discovery of exceptional points in the Bose-Einstein condensation of
gases with attractive 1/r-interaction | The extended Gross-Pitaevskii equation for the Bose-Einstein condensation of
gases with attractive 1/r-interaction has a second solution which is born
together with the ground state in a tangent bifurcation. At the bifurcation
point both states coalesce, i.e., the energies and the wave functions are
identical. We investigate the bifurcation point in the context of exceptional
points, a phenomenon known for linear non-Hermitian Hamiltonians. We point out
that the mean field energy, the chemical potential, and the wave functions show
the same behavior as an exceptional point in a linear, non-symmetric system.
The analysis of the analytically continued Gross-Pitaevskii equation reveals
complex waves at negative scattering lengths below the tangent bifurcation.
These solutions are interpreted as a decay of the condensate caused by an
absorbing potential.

711.4787 | Torsion and Supersymmetry Breaking | We identify the auxiliary fields in the hypermultiplets of type IIB string
theory compactified on a Calabi-Yau manifold, using a combination of worldsheet
and supergravity techniques. The SUSY-breaking squark and gaugino masses in
type IIB models depend on these auxiliary fields, which parametrize
deformations away from a pure Calabi-Yau compactification to one with NS-NS
3-form flux and SU(3) x SU(3) structure. Worldsheet arguments show that such
compactifications are generically globally nongeometric. Our results, combined
with earlier results for type IIA compactifications, imply that these
deformations are the mirrors of NS-NS 3-form flux, in accord with work from the
supergravity point of view. Using the worldsheet current algebra, we explain
why mirror symmetry may continue to hold in the presence of fluxes breaking the
symmetries (e.g., (2,2) SUSY) on which mirror symmetry is typically taken to
depend. Finally, we give evidence that nonperturbative worldsheet effects (such

711.4788 | Close-packed dimers on the kagome lattice: Finite lattices and the
Grassmannian approach | In a recent paper [ F. Wang and F. Y. Wu, Phys. Rev. E 75 (2007) 040105(R) ]
we reported exact results on the enumeration of close-packed dimers on an
infinite kagome lattice. We computed the per-dimer free energy using both the
Pfaffian approach and a vertex-model formulation, and found the result given by
a simple expression. We also reported results on dimer-dimer correlations
without giving details. In this paper we present details of the correlation
function analysis. In addition, we extend the exact enumeration to finite
lattices under two different boundary conditions and with asymmetric dimer
weights. For symmetric dimer weights the finite-lattice results are again
simple, and we show that they can be understood using a spin variable mapping.
We also describe the formulation of a Grassmannian functional integral approach
and apply it to the kagome lattice.

711.4789 | Lowest order QED radiative corrections to five-fold differential cross
section of hadron leptoproduction | The contribution of exclusive radiative tail to the cross section of
semi-inclusive hadron leptoproduction has been calculated exactly for the first
time. Although the experience of inclusive data analyses suggests us that the
contribution of radiative tail from the elastic peak is of particular
importance, similar effects in the semi-inclusive process were only recently
estimated in the peaking approximation. The explicit expressions for the lepton
part of the lowest order QED contribution of exclusive radiative tail to the
five-fold differential cross section are obtained and discussed. Numerical
estimates, provided within Jefferson Lab kinematic conditions, demonstrate

711.479 | Millihertz Oscillation Frequency Drift Predicts the Occurrence of Type I
X-ray Bursts | Millihertz quasi-periodic oscillations reported in three neutron-star low
mass X-ray binaries have been suggested to be a mode of marginally stable
nuclear burning on the neutron star surface. In this Letter, we show that close
to the transition between the island and the banana state, 4U~1636--53 shows
mHz QPOs whose frequency systematically decreases with time until the
oscillations disappear and a Type I X-ray burst occurs. There is a strong
correlation between the QPO frequency $\nu$ and the occurrence of X-ray bursts:
when $\nu\gtrsim9$ mHz no bursts occur, while $\nu\lesssim9$ mHz does allow the
occurrence of bursts. The mHz QPO frequency constitutes the first identified
observable that can be used to predict the occurrence of X-ray bursts. If a
systematic frequency drift occurs, then a burst happens within a few
kilo-seconds after $\nu$ drops below 9 mHz. This observational result confirms
that the mHz QPO phenomenon is intimately related with the processes that lead
to a thermonuclear burst.

711.4791 | Enhanced high-energy neutrino emission from choked gamma-ray bursts due
to meson and muon acceleration | It has been suggested that a potentially large fraction of supernovae could
be accompanied by relativistic outflows that stall below the stellar surface.
In this letter we point out that internal shocks that are believed to
accelerate protons to very high energies in these flows will also accelerate
secondary mesons and muons. As a result the neutrino spectrum from meson and
muon decay is expected to be much harder compared to previous estimates,

711.4792 | On the Capacity of a Class of MIMO Cognitive Radios | Cognitive radios have been studied recently as a means to utilize spectrum in
a more efficient manner. This paper focuses on the fundamental limits of
operation of a MIMO cognitive radio network with a single licensed user and a
single cognitive user. The channel setting is equivalent to an interference
channel with degraded message sets (with the cognitive user having access to
the licensed user's message). An achievable region and an outer bound is
derived for such a network setting. It is shown that under certain conditions,
the achievable region is optimal for a portion of the capacity region that
includes sum capacity.

711.4794 | Stochastic Acceleration in the Western Hotspot of Pictor A | Chandra's high resolution observations of radio galaxies require a revisit of
the relevant electron acceleration processes. Although the diffusive shock
particle acceleration model may explain spectra of spatially unresolved
sources, it encounters difficulties in explaining the structure and spectral
properties of recently discovered Chandra X-ray features in several low-power
radio sources. We argue that these observations strongly suggest stochastic
electron acceleration by magnetized turbulence, and show that the simplest
stochastic particle acceleration model with energy independent acceleration and
escape timescales can overcome most of these difficulties. We use the bright

distinguished by using one or more of the following criteria: (1) mass, (2)
luminosity, (3) size, (4) mass-to-light ratio and (5) spread in metallicity.
However, a few recently discovered objects show some overlap between the

demonstrate the formation of an artificial event horizon in optics. We observed
a classical optical effect, the blue-shifting of light at a white-hole horizon.
We also show by theoretical calculations that such a system is capable of
probing the quantum effects of horizons, in particular Hawking radiation.

711.4799 | Entanglement dynamics of two independent qubits in environments with and
without memory | A procedure to obtain the dynamics of $N$ independent qudits ($d$-level
systems) each interacting with its own reservoir, for any arbitrary initial
state, is presented. This is then applied to study the dynamics of the
entanglement of two qubits, initially in an extended Werner-like mixed state
with each of them in a zero temperature non-Markovian environment. The
dependence of the entanglement dynamics on the purity and degree of
entanglement of the initial states and on the amount of non-Markovianity is
also given. This extends the previous work about non-Markovian effects on the
two-qubit entanglement dynamics for initial Bell-like states [B. Bellomo
\textit{et al.}, Phys. Rev. Lett. \textbf{99}, 160502 (2007)]. The effect of
temperature on the two-qubit entanglement dynamics in a Markovian environment
is finally obtained.

711.4801 | Properties of newly formed dust by SN2006jc based on near-to-mid
infrared observation with AKARI | We present our latest results on near- to mid- infrared observation of
SN2006jc at 200 days after the discovery using the Infrared Camera (IRC) on
board $AKARI$. The near-infrared (2--5$\mu$m) spectrum of SN2006jc is obtained
for the first time and is found to be well interpreted in terms of the thermal
emission from amorphous carbon of 800$\pm 10$K with the mass of $6.9\pm 0.5
\times 10^{-5}M_{\odot}$ that was formed in the supernova ejecta. This dust
mass newly formed in the ejecta of SN 2006jc is in a range similar to those
obtained for other several dust forming core collapse supernovae based on
recent observations (i.e., $10^{-3}$--$10^{-5}$$M_{\odot}$). Mid-infrared
photometric data with {\it{AKARI}}/IRC MIR-S/S7, S9W, and S11 bands have shown
excess emission over the thermal emission by hot amorphous carbon of 800K. This
mid-infrared excess emission is likely to be accounted for by the emission from
warm amorphous carbon dust of 320$\pm 10$K with the mass of 2.7$^{+0.7}_{-0.5}
\times 10^{-3}M_{\odot}$ rather than by the band emission of astronomical
silicate and/or silica grains. This warm amorphous carbon dust is expected to
have been formed in the mass loss wind associated with the Wolf-Rayet stellar
activity before the SN explosion. Our result suggests that a significant amount
of dust is condensed in the mass loss wind prior to the SN explosion. A
possible contribution of emission bands by precursory SiO molecules in
7.5--9.5$\mu$m is also suggested.

711.4802 | On the physical parametrization and magnetic analogs of the Emparan-Teo
dihole solution | The Emparan-Teo non-extremal black dihole solution is reparametrized using
Komar quantities and the separation distance as arbitrary parameters. We show
how the potential $A_3$ can be calculated for the magnetic analogs of this
solution in the Einstein-Maxwell and Einstein-Maxwell-dilaton theories. We also

711.4803 | Stellar Feedback in Dwarf Galaxy Formation | Dwarf galaxies pose significant challenges for cosmological models. In
particular, current models predict a dark matter density that is divergent at
the center, in sharp contrast with observations which indicate an approximately
constant central density core. Energy feedback, from supernova explosions and
stellar winds, has been proposed as a major factor shaping the evolution of
dwarf galaxies. We present detailed cosmological simulations with sufficient
resolution both to model the relevant physical processes and to directly assess
the impact of stellar feedback on observable properties of dwarf galaxies. We
show that feedback drives large-scale, bulk motion of the interstellar gas
resulting in significant gravitational potential fluctuations and a consequent
reduction in the central matter density, bringing the theoretical predictions
in agreement with observations.

711.4804 | Flow of power-law fluids in self-affine fracture channels | The two-dimensional pressure driven flow of non-Newtonian power-law fluids in
self-affine fracture channels at finite Reynolds number is calculated. The
channels have constant mean aperture and two values $\zeta$=0.5 and 0.8 of the
Hurst exponent are considered. The calculation is based on the
lattice-Boltzmann method, using a novel method to obtain a power-law variation
in viscosity, and the behavior of shear-thinning, Newtonian and
shear-thickening liquids is compared. Local aspects of the flow fields, such as
maximum velocity and pressure fluctuations, were studied, and the non-Newtonian
fluids were compared to the (previously-studied) Newtonian case. The
permeability results may be collapsed into a master curve of friction factor
vs. Reynolds number using a scaling similar to that employed for porous media
flow, and exhibits a transition from a linear regime to a more rapid variation

711.4805 | Deeply Virtual Compton Scattering Beam-Spin Asymmetries | The beam spin asymmetries in the hard exclusive electroproduction of photons
on the proton (ep -> epg) were measured over a wide kinematic range and with
high statistical accuracy. These asymmetries result from the interference of
the Bethe-Heitler process and of deeply virtual Compton scattering. Over the
whole kinematic range (x_B from 0.11 to 0.58, Q^2 from 1 to 4.8 GeV^2, -t from
0.09 to 1.8 GeV^2), the azimuthal dependence of the asymmetries is compatible
with expectations from leading-twist dominance, A = a*sin(phi)/[1+c*cos(phi)].
This extensive set of data can thus be used to constrain significantly the
generalized parton distributions of the nucleon in the valence quark sector.

evolves from the main sequence directly to the helium main sequence. We use the
time-dependent wind parameters, such as mass loss rate, wind velocity and
rotation-induced wind anisotropy from the evolution model as input for a 2D
hydrodynamical simulation. While the outer edge of the pressure-driven
circumstellar bubble is spherical, the circumstellar medium close to the star
shows strong non-spherical features during and after the periods of
near-critical rotation. We conclude that the circumstellar medium around
rapidly rotating massive stars differs considerably from the surrounding
material of non-rotating stars of similar mass. Multiple blue-shifted high
velocity absorption components in gamma-ray burst afterglow spectra are
predicted. As a consequence of near critical rotation and short stellar
evolution time scales during the last few thousand years of the star's life, we
find a strong deviation of the circumstellar density profile in the polar
direction from the 1/R^2 density profile normally associated with stellar winds
close to the star
