711.3109 | Monitoring derivation of the quantum linear Boltzmann equation | We show how the effective equation of motion for a distinguished quantum
particle in an ideal gas environment can be obtained by means of the monitoring
approach introduced in [EPL 77, 50007 (2007)]. The resulting Lindblad master
equation accounts for the quantum effects of the scattering dynamics in a
non-perturbative fashion and it describes decoherence and dissipation in a
unified framework. It incorporates various established equations as limiting
cases and reduces to the classical linear Boltzmann equation once the state is
diagonal in momentum.

711.311 | Covariance and meaning | Several other factors, besides the intrinsic local geometry, contribute to
give a meaning to a space-time model. The simplest example comes from comparing
Minkowski's and Milne's model, that both have a null Riemann tensor. We add to
these two models a third one which describes a time-dependent
locally-Minkowskian spherically symmetric space-time on which every
test-particle at rest with respect to the center of symmetry sustains a
constant force. Although the model is globally grossly un-realistic we think
that it can be helpful to describe a local perturbation of an homogeneous
cosmological model. Or as a substitute to the very far away asymptotic
Minkowskian behavior usually assumed to describe the gravitational field of
compact spherical bodies.

711.3111 | Quantum Secret Sharing with Multi-level Mutually (Un-)Biased Bases | We construct general schemes for multi-partite quantum secret sharing using
multi-level systems, and find that the consistent conditions for valid
measurements can be summarized in two simple algebraic conditions. The scheme
using the very high dimensional mutually unbiased bases can in principle
achieve perfect security against intercept-resend attack; and for the scheme
using mutually biased bases, it reaches the optimal but non-perfect security at
4-level system. We also address the security issue against the general attacks
in the context of our multi-level schemes. Especially, we propose new protocol
to enhance both the efficiency and the security against the
entanglement-assisted participant's attack by incorporating

711.3112 | Large-scale horizontal flows in the solar photosphere III: Effects on
filament destabilization | We study the influence of large-scale photospheric motions on the
estabilization of an eruptive filament, observed on October 6, 7, and 8, 2004,
as part of an international observing campaign (JOP 178). Large-scale
horizontal flows were invetigated from a series of MDI full-disc Dopplergrams
and magnetograms. From the Dopplergrams, we tracked supergranular flow patterns
using the local correlation tracking (LCT) technique. We used both LCT and
manual tracking of isolated magnetic elements to obtain horizontal velocities
from magnetograms. We find that the measured flow fields obtained by the
different methods are well-correlated on large scales. The topology of the flow
field changed significantly during the filament eruptive phase, suggesting a
possible coupling between the surface flow field and the coronal magnetic
field. We measured an increase in the shear below the point where the eruption
starts and a decrease in shear after the eruption. We find a pattern in the
large-scale horizontal flows at the solar surface that interact with
differential rotation. We conclude that there is probably a link between
changes in surface flow and the disappearance of the eruptive filament.

711.3113 | Screening and impurity ionization energy in semiconductors | Usually microscopic electrostatic field around charged impurity ions is
neglected when the ionization energy is concerned. The ionization energy is
considered to be equal to that of a lonely impurity atom. Here the energy of
the electrostatic field around charged impurity ions in semiconductor is taken
into account. It is shown that the energy of this field contributes to decrease

711.3115 | Does the Chapman--Enskog expansion for sheared granular gases converge? | The fundamental question addressed in this paper is whether the partial
Chapman--Enskog expansion $P_{xy}=-\sum_{k=0}^\infty \eta_k ({\partial
u_x}/{\partial y})^{2k+1}$ of the shear stress converges or not for a gas of
inelastic hard spheres. By using a simple kinetic model it is shown that, in
contrast to the elastic case, the above series does converge, the radius of
convergence increasing with inelasticity. It is argued that this paradoxical
conclusion is not an artifact of the kinetic model and can be understood in
terms of the time evolution of the scaled shear rate in the uniform shear flow.

711.3116 | Seeking better times: atomic clocks in the generalized Tonks-Girardeau
regime | This article is based on the talk with the same title at the Blaubeuren
meeting. First we discuss briefly the importance of time and time keeping,
explaining the basic functioning of clocks in general and atomic clocks in
particular, which rely on Ramsey interferometry. The usefulness of cold atoms
is discussed as well as their limits in Bose-Einstein condensates. An
alternative that we study is a different cold-atom regime: the Tonks-Girardeau
(TG) gas of tightly confined and strongly interacting bosons. The TG gas is

711.3118 | On the existence of exotic and non-exotic multiquark meson states | To obtain an exact solution of a four-body system containing two quarks and
two antiquarks interacting through two-body terms is a cumbersome task that has
been tackled with more or less success during the last decades. We present an
exact method for the study of four-quark systems based on the hyperspherical
harmonics formalism that allows us to solve it without resorting to further
approximations, like for instance the existence of diquark components. We apply
it to systems containing two heavy and two light quarks using different
quark-quark potentials. While $QQ\bar n \bar n$ states may be stable in nature,
the stability of $Q\bar Qn \bar n$ states would imply the existence of quark
correlations not taken into account by simple quark dynamical models.

711.3119 | Chiral symmetry breaking and Lorentz nature of confinement | The Lorentz nature of confinement in a heavy-light quarkonium is
investigated. It is demonstrated that an effective scalar interaction is
generated selfconsistently as a result of chiral symmetry breaking, and this

711.3121 | Evidence of triple collision dynamics in partial photo-ionisation cross
sections of helium | Experimental results on partial photo-ionisation cross sections of helium are
analysed in the light of recent advances in the semiclassical theory of
two-electron atoms. Byun et al (arXiv:physics/0701086) predict that the total
photo-ionisation cross section below the double-ionisation threshold can,
semiclassically, be described in terms of contributions associated with
classical orbits starting and ending in the triple collision. The necessary
modifications of the semiclassical theory for partial cross sections is
developed here. It is argued that partial cross sections are also dominated by
the triple collision dynamics. The expected semiclassical contributions can be
identified in the Fourier transformation of the experimental data. This clearly
demonstrates for the first time the validity of the basic assumptions made in
Byun et al. Our findings explain furthermore in a natural way the self-similar
structures observed in cross section signals for different channel numbers.

711.3122 | Conflict between the identification of cosmic neutrino source and the
sensitivity to mixing angles in neutrino telescope | Neutrino fluxes at telescopes depend on both initial fluxes out of
astronomical bursts and flavor mixing during their travel to the earth.
However, since the information on the initial composition requires better
precision in mixing angles and vice versa, the neutrino detection at telescopes
for itself cannot provide solutions to the both problems. Thus, a probability
to be measured at long baseline oscillation is considered as a complement to

711.3124 | Dark Energy and Structure Formation: Connecting the Galactic and
Cosmological Length Scales | On the cosmological length scale, recent measurements by WMAP have validated
$\Lambda$CDM to a precision not see before in cosmology. Such is not the case
on galactic length scales, however, where the `cuspy-core' problem has
demonstrated our lack of understanding of structure formation. Here, we propose
a solution to the 'cuspy-core' problem based on the observation that with the
discovery of Dark Energy, $\Lambda_{DE}$, there is now a universal length
scale, $\lambda_{DE}=c/(\Lambda_{DE} G)^{1/2}$, associated with the universe.
This length scale allows for an extension of the geodesic equations of motion
that affects only the motion of massive test particles; the motion of massless
test particles are not affected, and such phenomenon as gravitational lensing
remain unchanged. An evolution equation for the density profile is derived, and
an effective free energy density functional for it is constructed. We
conjecture that the pseudoisothermal profile is preferred over the cusp-like
profile because it has a lower effective free energy. A cosmological check of
the theory is made using the observed rotational velocities and core sizes of
1393 spiral galaxies. We calculate $\sigma_8$ to be $0.68_{\pm0.11}$; this is
within experimental error of the WMAP value $0.761_{-0.048}^{+0.049}$. We then
calculate $R_{200}=270_{\pm 130}$ kpc, which is in agreement with observations.
We estimate the fractional density of matter that cannot be determined through
gravity to be $0.197_{\pm 0.017}$; this is nearly equal to the WMAP value for
the fractional density of nonbaryonic matter $0.196^{+0.025}_{-0.026}$. The
fractional density of matter that can be determined through gravity is then
calculated to be $0.041_{-0.031}^{+0.030}$; this is nearly equal to
$\Omega_B=0.0416_{-0.0039}^{+0.0038}$.

711.3125 | Sources of SEP Acceleration during a Flare-CME Event | A high-speed halo-type coronal mass ejection (CME), associated with a GOES
M4.6 soft X-ray flare in NOAA AR 0180 at S12W29 and an EIT wave and dimming,
occurred on 9 November 2002. A complex radio event was observed during the same
period. It included narrow-band fluctuations and frequency-drifting features in
the metric wavelength range, type III burst groups at metric--hectometric
wavelengths, and an interplanetary type II radio burst, which was visible in
the dynamic radio spectrum below 14 MHz. To study the association of the
recorded solar energetic particle (SEP) populations with the propagating CME
and flaring, we perform a multi-wavelength analysis using radio spectral and
imaging observations combined with white-light, EUV, hard X-ray, and
magnetogram data. Velocity dispersion analysis of the particle distributions
(SOHO and Wind in situ observations) provides estimates for the release times
of electrons and protons. Our analysis indicates that proton acceleration was
delayed compared to the electrons. The dynamics of the interplanetary type II
burst identify the burst source as a bow shock created by the fast CME. The
type III burst groups, with start times close to the estimated electron release
times, trace electron beams travelling along open field lines into the
interplanetary space. The type III bursts seem to encounter a steep density
gradient as they overtake the type II shock front, resulting in an abrupt
change in the frequency drift rate of the type III burst emission. Our study
presents evidence in support of a scenario in which electrons are accelerated
low in the corona behind the CME shock front, while protons are accelerated
later, possibly at the CME bow shock high in the corona.

711.3127 | On the study of local stress rearrangements during quasistatic plastic
shear of a model glass: do local stress components contain enough
information? | We present a numerical study of the mechanical response of a 2D Lennard-Jones
amorphous solid under steady quasistatic and athermal shear. We focus here on
the evolution of local stress components. While the local stress is usually
taken as an order parameter in the description of the rheological behaviour of
complex fluids, and for plasticity in glasses, we show here that the knowledge
of local stresses is not sufficient for a complete description of the plastic
behaviour of our system. The distribution of local stresses can be
approximately described as resulting from the sum of localized quadrupolar
events with an exponential distribution of amplitudes. However, we show that

711.3128 | Entity Ranking in Wikipedia | The traditional entity extraction problem lies in the ability of extracting
named entities from plain text using natural language processing techniques and
intensive training from large document collections. Examples of named entities
include organisations, people, locations, or dates. There are many research
activities involving named entities; we are interested in entity ranking in the
field of information retrieval. In this paper, we describe our approach to
identifying and ranking entities from the INEX Wikipedia document collection.
Wikipedia offers a number of interesting features for entity identification and
ranking that we first introduce. We then describe the principles and the
architecture of our entity ranking system, and introduce our methodology for
evaluation. Our preliminary results show that the use of categories and the
link structure of Wikipedia, together with entity examples, can significantly
improve retrieval effectiveness.

711.3129 | Spherical collapse in modified gravity with the Birkhoff-theorem | We study structure formation in a phenomenological model of modified gravity
which interpolates between LambdaCDM and phenomenological DGP-gravity.
Generalisation of spherical collapse by using the Birkhoff-theorem along with
the modified growth equation shows that the overdensity for spherical collapse
delta_c in these models is significantly lowered compared to LambdaCDM, leading
to enhanced number densities of massive clusters and enhanced cluster merging
rates. We find that delta_c(z) is well fitted by a function of the form
delta_c(z) = a - b\exp(-cz). We examine the sensitivity of PLANCK's and SPT's
Sunyaev-Zel'dovich survey to constrain the modified gravity parameterisation
and find that these experiments can easily distinguish between models with a

711.313 | There is no axiomatic system for the quantum theory | Recently, [arXiv:0810.3134] is accepted and published. We derive an
inequality with two settings as tests for the existence of the Bloch sphere in
a spin-1/2 system. The probability theory of measurement outcome within the
formalism of von Neumann projective measurement violates the inequality.
Namely, we have to give up the existence of the Bloch sphere. Or, we have to
give up the probability theory of measurement outcome within the formalism of
von Neumann projective measurement. Hence it turns out that there is a
contradiction in the Hilbert space formalism of the quantum theory, viz., there
is no axiomatic system for the theory.

711.3131 | Kolmogorov-Sinai and Bekenstein-Hawking entropies | It is shown that instability of stringy matter near the event horizon of a
black hole (the spreading effect) can be characterized by the Lyapunov
exponents. The Kolmogorov-Sinai entropy is the sum of all the positive Lyapunov
exponents and equals to the inverse gravitational radius. Due to a replacement
of the configuration space of a string by its phase space at distance of order
of the string scale, the relation between the Kolmogorov-Sinai and
Bekenstein-Hawking entropies is established. The KS entropy of a black hole
measures the rate at which information about the state of a string collapsing

711.3134 | Poles of the topological zeta function associated to an ideal in
dimension two | To an ideal in $\mathbb{C}[x,y]$ one can associate a topological zeta
function. This is an extension of the topological zeta function associated to
one polynomial. But in this case we use a principalization of the ideal instead
of an embedded resolution of the curve.
In this paper we will study two questions about the poles of this zeta
function. First, we will give a criterion to determine whether or not a
candidate pole is a pole. It turns out that we can know this immediately by
looking at the intersection diagram of the principalization, together with the
numerical data of the exceptional curves. Afterwards we will completely
describe the set of rational numbers that can occur as poles of a topological
zeta function associated to an ideal in dimension two. The same results are
valid for related zeta functions, as for instance the motivic zeta function.
| math.AG | to an ideal in mathbbcxy one can associate a topological zeta function this is an extension of the topological zeta function associated to one polynomial but in this case we use a principalization of the ideal instead of an embedded resolution of the curve in this paper we will study two questions about the poles of this zeta function first we will give a criterion to determine whether or not a candidate pole is a pole it turns out that we can know this immediately by looking at the intersection diagram of the principalization together with the numerical data of the exceptional curves afterwards we will completely describe the set of rational numbers that can occur as poles of a topological zeta function associated to an ideal in dimension two the same results are valid for related zeta functions as for instance the motivic zeta function | [['to', 'an', 'ideal', 'in', 'mathbbcxy', 'one', 'can', 'associate', 'a', 'topological', 'zeta', 'function', 'this', 'is', 'an', 'extension', 'of', 'the', 'topological', 'zeta', 'function', 'associated', 'to', 'one', 'polynomial', 'but', 'in', 'this', 'case', 'we', 'use', 'a', 'principalization', 'of', 'the', 'ideal', 'instead', 'of', 'an', 'embedded', 'resolution', 'of', 'the', 'curve', 'in', 'this', 'paper', 'we', 'will', 'study', 'two', 'questions', 'about', 'the', 'poles', 'of', 'this', 'zeta', 'function', 'first', 'we', 'will', 'give', 'a', 'criterion', 'to', 'determine', 'whether', 'or', 'not', 'a', 'candidate', 'pole', 'is', 'a', 'pole', 'it', 'turns', 'out', 'that', 'we', 'can', 'know', 'this', 'immediately', 'by', 'looking', 'at', 'the', 'intersection', 'diagram', 'of', 'the', 'principalization', 'together', 'with', 'the', 'numerical', 'data', 'of', 'the', 'exceptional', 'curves', 'afterwards', 'we', 'will', 'completely', 'describe', 'the', 'set', 'of', 'rational', 'numbers', 'that', 'can', 'occur', 'as', 'poles', 'of', 'a', 'topological', 'zeta', 'function', 'associated', 'to', 'an', 'ideal', 'in', 'dimension', 'two', 'the', 'same', 'results', 'are', 'valid', 'for', 'related', 'zeta', 'functions', 'as', 'for', 'instance', 'the', 'motivic', 'zeta', 'function']] | [-0.19467758754115194, 0.07092223703033572, -0.16512325280409765, 0.10827593763808604, -0.09989169992391683, -0.09957896417313039, 0.04925818790200052, 0.3278336826048485, -0.3097332316667658, -0.21839151821778577, 0.1048928082290493, -0.24889904081068728, -0.1851076519017886, 0.20577301432805978, -0.06150894854313452, 0.0069925246205282945, 0.0038666001470019557, 0.09548109222509682, -0.09624957691635681, -0.2747160029495518, 0.39001991926398993, 0.01499128159875535, 0.14778872460688222, 0.06895507364342474, 0.06171332737697051, 0.008473582974035446, 0.0027567452690500306, 0.003202731504219852, -0.1519608481103205, 0.08239218441941712, 0.2723618881036974, 0.10857933844688464, 0.2370585319729624, -0.3552604799337481, -0.14650290628116935, 0.1470213559430654, 0.17391705225630064, 0.027586869074172047, 0.01741340106244722, -0.18275114614994917, 0.12800015200069811, -0.15114118177316163, -0.22019731728615213, -0.05047670024612995, 0.014652941178224266, 0.023506896039279662, -0.2735031600180401, 0.0019317116358712927, 0.0314020770538139, 0.07687837908950264, -0.05523106271292606, -0.10395969089426815, -0.007368589545702179, 0.12806715698648014, 0.027465311803995338, 0.07711252986217454, 0.0598295299840249, -0.16720539233679182, -0.10884250782761876, 0.36284612513734155, -0.0562401318241689, -0.2118516210402834, 0.18081362515668806, -0.184242550848205, -0.1481356258625292, 0.11631374956548775, 0.09523653815187871, 0.14932480531310893, -0.11163940813315854, 0.06862760513816794, -0.09780623702721492, 0.13955232503422063, 0.08903797517677335, -0.022692600413455232, 0.24810638557481643, 0.07313826599171104, 0.05608266798702821, 0.19467479456455306, -0.06189064030959717, -0.027223298163472177, -0.3607847246864479, -0.2333347047615337, -0.18256994866772414, 0.09832718405979829, -0.05233785662040982, -0.19863409482657093, 0.42365577241584457, 0.13248754005356092, 0.2359586893006751, 0.0483423439348882, 0.25114904874170274, 0.15168068168155788, 0.06484906206924902, 0.0019710693860822037, 0.16072009583577923, 0.1041448154799283, 0.032932151144064246, -0.1470477114709043, 0.02182286028903335, 0.11824136631155055] |
711.3135 | Cluster geometry and survival probability in systems driven by
reaction-diffusion dynamics | We consider a reaction-diffusion model incorporating the reactions A -> 0, A
-> 2A and 2A -> 3A. Depending on the relative rates for sexual and asexual
reproduction of the quantity A, the model exhibits either a continuous or
first-order absorbing phase transition to an extinct state. A tricritical point
separates the two phase lines. As well as briefly examining this critical
behavior in 2+1 dimensions, we pay particular attention to the cluster
geometry. We observe the different cluster structures that form at criticality
for the three different types of critical behavior and show that there exists a
linear relationship for the probability of survival against initial cluster
size at the tricritical point only.

711.3136 | Positive association in the fractional fuzzy Potts model | A fractional fuzzy Potts measure is a probability distribution on spin
configurations of a finite graph $G$ obtained in two steps: first a subgraph of
$G$ is chosen according to a random cluster measure $\phi_{p,q}$, and then a
spin ($\pm1$) is chosen independently for each component of the subgraph and
assigned to all vertices of that component. We show that whenever $q\geq1$,
such a measure is positively associated, meaning that any two increasing events
are positively correlated. This generalizes earlier results of

711.3138 | Non-Markovian decoherence and disentanglement scenarios in quantum
Brownian motion | We study the non-Markovian decoherence and disentanglement dynamics of
dissipative quantum systems with special emphasis on non-Gaussian continuous
variable systems. The dynamics are described by the Hu-Paz-Zhang master
equation of quantum Brownian motion. The time evolution of the decoherence
function of a single-mode superposition is compared to the concurrence of a
two-mode entangled state. It is verified that moderate non-Markovian influences
slow down the decay of interference fringes and quantum correlations, while
strong non-Markovian effects resulting from an out-of-resonance bath can even
accelerate the loss of coherence, compared to predictions of Markovian
approximations. Qualitatively different scenarios including exponential,
Gaussian or algebraic decay of the decoherence function are analyzed. It is
shown that partial revivals of coherence can occur in case of non-Lindblad-type
dynamics.

711.314 | X-Ray Emitting Ejecta of Supernova Remnant N132D | The brightest supernova remnant in the Magellanic Clouds, N132D, belongs to
the rare class of oxygen-rich remnants, about a dozen objects that show optical
emission from pure heavy-element ejecta. They originate in explosions of
massive stars that produce large amounts of O, although only a tiny fraction of
that O is found to emit at optical wavelengths. We report the detection of
substantial amounts of O at X-ray wavelengths in a recent 100 ks Chandra ACIS
observation of N132D. A comparison between subarcsecond-resolution Chandra and
Hubble images reveals a good match between clumpy X-ray and optically emitting
ejecta on large (but not small) scales. Ejecta spectra are dominated by strong
lines of He- and H-like O; they exhibit substantial spatial variations
partially caused by patchy absorption within the LMC. Because optical ejecta
are concentrated in a 5 pc radius elliptical expanding shell, the detected
ejecta X-ray emission also originates in this shell.

711.3143 | Covariant Helicity-Coupling Amplitudes: A New Formulation | We have worked out covariant amplitudes for any two-body decay of a resonance
with an arbitrary non-zero mass, which involves arbitrary integer spins in the
initial and the final states. One key new ingredient for this work is the
application of the total intrinsic spin operator $\vec S$ which is given
directly in terms of the generators of the Poincar\'e group.
Using the results of this study, we show how to explore the Lorentz factors
which appear naturally, if the momentum-space wave functions are used to form
the covariant decay amplitudes. We have devised a method of constructing our
covariant decay amplitudes, such that they lead to the Zemach amplitudes when
the Lorentz factors are set one.

711.3144 | Interacting Jets from Binary Protostars | We investigate potential models that could explain why multiple proto-stellar
systems predominantly show single jets. During their formation, stars most
frequently produce energetic outflows and jets. However, binary jets have only
been observed in a very small number of systems. We model numerically 3D binary
jets for various outflow parameters. We also model the propagation of jets from
a specific source, namely L1551 IRS 5, known to have two jets, using recent
observations as constraints for simulations with a new MHD code. We examine
their morphology and dynamics, and produce synthetic emission maps. We find
that the two jets interfere up to the stage where one of them is almost
destroyed or engulfed into the second one. We are able to reproduce some of the
observational features of L1551 such as the bending of the secondary jet. While
the effects of orbital motion are negligible over the jets dynamical timeline,
their interaction has significant impact on their morphology. If the jets are

711.3145 | The physical interpretation of the spectrum of black hole quasinormal
modes | When a classical black hole is perturbed, its relaxation is governed by a set
of quasinormal modes with complex frequencies \omega= \omega_R+i\omega_I. We
show that this behavior is the same as that of a collection of damped harmonic
oscillators whose real frequencies are (\omega_R^2+\omega_I^2)^{1/2}, rather
than simply \omega_R. Since, for highly excited modes, \omega_I >> \omega_R,
this observation changes drastically the physical understanding of the black
hole spectrum, and forces a reexamination of various results in the literature.
In particular, adapting a derivation by Hod, we find that the area of the
horizon of a Schwarzschild black hole is quantized in units \Delta
A=8\pi\lpl^2, where \lpl is the Planck length (in contrast with the original
result \Delta A=4\log(3) \lpl^2). The resulting area quantization does not
suffer from a number of difficulties of the original proposal; in particular,
it is an intrinsic property of the black hole, independent of the spin of the
perturbation.

711.3146 | Quantum model of microcavity intersubband electroluminescent devices | We present a quantum theoretical analysis of the electroluminescence from an
intersubband transition of a quantum well structure embedded in a planar
microcavity. By using a cluster factorization method, we have derived a closed
set of dynamical equations for the quantum well carrier and cavity photon
occupation numbers, the correlation between the cavity field and the
intersubband polarization, as well as polarization-polarization contributions.
In order to model the electrical excitation, we have considered electron
population tunneling from an injector and into an extractor contact. The
tunneling rates have been obtained by considering the bare electronic states in
the quantum well and the limit of validity of this approximation (broad-band
injection) are discussed in detail. We apply the present quantum model to
provide a comprehensive description of the electronic transport and optical
properties of an intersubband microcavity light emitting diode, accounting for
non-radiative carrier relaxation and Pauli blocking. We study the enhancement

711.3147 | Object oriented data analysis: Sets of trees | Object oriented data analysis is the statistical analysis of populations of
complex objects. In the special case of functional data analysis, these data
objects are curves, where standard Euclidean approaches, such as principal
component analysis, have been very successful. Recent developments in medical
image analysis motivate the statistical analysis of populations of more complex
data objects which are elements of mildly non-Euclidean spaces, such as Lie
groups and symmetric spaces, or of strongly non-Euclidean spaces, such as
spaces of tree-structured data objects. These new contexts for object oriented
data analysis create several potentially large new interfaces between
mathematics and statistics. This point is illustrated through the careful
development of a novel mathematical framework for statistical analysis of
populations of tree-structured objects.

711.3152 | Multipath Channels of Bounded Capacity | The capacity of discrete-time, non-coherent, multipath fading channels is
considered. It is shown that if the delay spread is large in the sense that the

711.3153 | Induction of nuclear fission by high-voltage application | In nuclear power generation, fissile materials are mainly used. For example,
$U^{235}$ is fissile and therefore quite essential for use of nuclear energy.
However, the material $U^{235}$ has very small natural abundance less than 1 %.
We should seek possibility of utilizing fissionable materials such as $U^{238}$
because natural abundance of such fissionable materials is generally much
larger than fissile ones. In this paper, we show that thermal neutrons with
vanishing kinetic energy can induce nuclear fission when high voltage is
applied to fissionable materials. To obtain this result, we use the liquid-drop
model for nuclei. Finally, we propose how fissionable materials can be
utilized.

711.3154 | In-medium chiral condensate beyond linear density approximation | In-medium chiral perturbation theory is used to calculate the density
dependence of the quark condensate $<\bar qq>$. The corrections beyond the
linear density approximation are obtained by differentiating the interaction
contributions to the energy per particle of isospin-symmetric nuclear matter
with respect to the pion mass. Our calculation treats systematically the
effects from one-pion exchange (with $m_\pi$-dependent vertex corrections),
iterated $1\pi$-exchange, and irreducible $2\pi$-exchange including
intermediate $\Delta(1232)$-isobar excitations, with Pauli-blocking corrections
up to three-loop order. We find a strong and non-linear dependence of the
``dropping'' in-medium condensate on the actual value of the pion (or light
quark) mass. In the chiral limit, $m_\pi=0$, chiral restoration appears to be
reached already at about 1.5 times normal nuclear matter density. By contrast,
for the physical pion mass, $m_\pi = 135 $MeV, the in-medium condensate
stabilizes at about 60% of its vacuum value above that same density. Effects
from $2\pi$-exchange with virtual $\Delta(1232)$-isobar excitations turn out to
be crucial in generating such pronounced deviations from the linear density
approximation above $\rho_0$. The hindered tendency towards chiral symmetry
restoration provides a justification for using pions and nucleons as effective
low-energy degrees of freedom at least up to twice nuclear matter density.

711.3155 | Klein paradox and Scattering theory for the semi-classical Dirac
equation | We study the Klein paradox for the semi-classical Dirac operator on $\R$ with
potentials having constant limits, not necessarily the same at infinity. Using
the complex WKB method, the time-independent scattering theory in terms of
incoming and outgoing plane wave solutions is established. The corresponding
scattering matrix is unitary. We obtain an asymptotic expansion, with respect
to the semi-classical parameter $h$, of the scattering matrix in the cases of
the Klein paradox, the total transmission and the total reflection. Finally, we
treat the scattering problem in the zero mass case.

711.3156 | Three-Dimensional Ising-Like System in an External Field: Microscopic
Calculation of the Free Energy in the Higher Non-Gaussian Approximation | An analytic method for deriving the free energy of a three-dimensional
Ising-like system near the critical point in a homogeneous external field is
developed in the $\rho^6$ model approximation. The mathematical description
proposed for temperatures $T>T_c$ ($T_c$ is the phase-transition temperature in
the absence of an external field) is valid for fields near $\tilde h_c$, where
the scaling variable is of the order of unity and power series in this variable
are not effective. At the limiting field $\tilde h_c$, the temperature and
field effects on the system in the vicinity of the critical point are
equivalent. The total free energy is obtained as a function of temperature,
field and microscopic parameters of the system without using series expansions
in the scaling variable. In addition to leading terms, the expression for the
free energy includes the terms determining the temperature and field confluent
corrections.

711.3158 | Algorithm for muon electromagnetic shower reconstruction | The ANTARES neutrino telescope is presently being built in the Mediterranean
Sea at a depth of 2500 m. The primary aim of the experiment is the detection of
high energy cosmic muon neutrinos, which are identified by the muons that are
produced in charged current interactions. These muons are detected by measuring
the Cerenkov light which they emit traversing the detector. Sometimes a high
momentum muon produces electromagnetic showers. The subject of this paper is a
method to reconstruct these showers which includes several steps: an algorithm
for the fit of the muon track parameters, preselection of detected photons
belonging to a shower, and a final fit with the preselected detected photons to
calculate the electromagnetic shower position. Finally a comparison between
data obtained with that part of the detector that is currently in operation and
simulations is presented.

powers of a given set of integers. We show that the property of recurrence for
some given values of $k$ does not give any constraint on the recurrence for the
other powers. This is motivated by similar results in number theory concerning
additive basis of natural numbers. Moreover, motivated by a result of Kamae and
Mend\`es-France, that links single recurrence with uniform distribution
properties of sequences, we look for an analogous result dealing with higher
order recurrence and make a related conjecture.

TeV with high pT leptons | We present a search for the associated production of charginos and
neutralinos in p-pbar collisions at 1.96 TeV. The data were collected at the
Collider Detector at Fermilab (CDF II) and correspond to integrated
luminosities between 0.7 and 1.0 fb-1. We look for final states with one high
pT electron or muon, and two additional leptons. Our results are consistent
with the standard model expectations, and we set limits on the cross section as
a function of the chargino mass in three different supersymmetric scenarios.
For a specific MSSM scenario with no slepton mixing we set a 95 % C.L. limit at
151 GeV/c^2.

711.3163 | Invariant functions in Denjoy-Carleman classes | Let $V$ be a real finite dimensional representation of a compact Lie group
$G$. It is well-known that the algebra $\mathbb R[V]^G$ of $G$-invariant
polynomials on $V$ is finitely generated, say by $\sigma_1,...,\sigma_p$.
Schwarz proved that each $G$-invariant $C^\infty$-function $f$ on $V$ has the
form $f=F(\sigma_1,...,\sigma_p)$ for a $C^\infty$-function $F$ on $\mathbb
R^p$. We investigate this representation within the framework of
Denjoy-Carleman classes. One can in general not expect that $f$ and $F$ lie in
the same Denjoy-Carleman class $C_M$ (with $M=(M_k)$). For finite groups $G$
and (more generally) for polar representations $V$ we show that for each
$G$-invariant $f$ of class $C_M$ there is an $F$ of class $C_N$ such that
$f=F(\sigma_1,...,\sigma_p)$, if $N$ is strongly regular and satisfies $N_k \ge
M_{km} \ep^{k+1}$, for all $k$, with $m$ an (explicitly known) integer
depending only on the representation and $\epsilon>0$ independent of $k$. In
particular, each $G$-invariant $(1+\delta)$-Gevrey function $f$ has the form
$f=F(\sigma_1,...,\sigma_p)$ for a $(1+\delta m)$-Gevrey function $F$.
Applications to equivariant functions and basic differential forms are given.

711.3164 | Power-law corrections to black-hole entropy via entanglement | We consider the entanglement between quantum field degrees of freedom inside
and outside the horizon as a plausible source of black-hole entropy. We examine
possible deviations of black hole entropy from area proportionality. We show
that while the area law holds when the field is in its ground state, a
correction term proportional to a fractional power of area results when the
field is in a superposition of ground and excited states. We compare our
results with the other approaches in the literature.

711.3165 | CFT Interpretation of Merging Multiple SLE Traces | In this paper we give a physical interpretation of the probability of a
Stochastic Loewner Evolution (SLE) trace approaching a marked point in the
upper half plane, e.g. on another trace. Our approach is based on the concept
of fusion of boundary with bulk or other boundary fields in Conformal Field

711.3166 | Walls and chains of planar skyrmions | In planar (baby) Skyrme systems, there may be extended linear structures
which resemble either domain walls or chains of skyrmions, depending on the
choice of potential and boundary conditions. We show that systems with a single
vacuum, for example with potential V=1-phi_3, admit chain solutions, whereas
walls are ruled out by the uniqueness of the vacuum. On the other hand, in
double-vacuum systems such as V=1/2*(1-phi_3^2), one has stable wall solutions,
but there are no stable chains; the walls may be viewed as the primary objects
in such systems, with skyrmions being made out of them.

711.3168 | CME Propagation Characteristics from Radio Observations | We explore the relationship among three coronal mass ejections (CMEs),
observed on 28 October 2003, 7 November 2004, and 20 January 2005, the type II
burst-associated shock waves in the corona and solar wind, as well as the
arrival of their related shock waves and magnetic clouds at 1 AU. Using six
different coronal/interplanetary density models, we calculate the speeds of
shocks from the frequency drifts observed in metric and decametric radio wave
data. We compare these speeds with the velocity of the CMEs as observed in the
plane-of-the-sky white-light observations and calculated with a cone model for
the 7 November 2004 event. We then follow the propagation of the ejecta using
Interplanetary Scintillation (IPS) measurements, which were available for the 7
November 2004 and 20 January 2005 events. Finally, we calculate the travel time
of the interplanetary (IP) shocks between the Sun and Earth and discuss the
velocities obtained from the different data. This study highlights the
difficulties in making velocity estimates that cover the full CME propagation

711.3169 | Exactly Solvable Model for the QCD Tricritcal Endpoint | An inclusion of temperature and chemical potential dependent surface tension
into the gas of quark-gluon bags model resolves a long standing problem of a
unified description of the first and second order phase transition with the
cross-over. The suggested model has an exact analytical solution and allows one
to rigorously study the vicinity of the critical endpoint of the deconfinement
phase transition. It is found that at the curve of a zero surface tension
coefficient there must exist the surface induced phase tranition of the 2-nd or
higher order. The present model predicts that the critical endpoint (CEP) of
quantum chromodynamics is the tricritical endpoint.

711.3172 | Assessing non-Markovian dynamics | We investigate what a snapshot of a quantum evolution - a quantum channel
reflecting open system dynamics - reveals about the underlying continuous time
evolution. Remarkably, from such a snapshot, and without imposing additional
assumptions, it can be decided whether or not a channel is consistent with a
time (in)dependent Markovian evolution, for which we provide computable
necessary and sufficient criteria. Based on these, a computable measure of
`Markovianity' is introduced. We discuss how the consistency with Markovian
dynamics can be checked in quantum process tomography. The results also clarify
the geometry of the set of quantum channels with respect to being solutions of
time (in)dependent master equations.

711.3173 | T=0 effective interaction in 14N and 10B | We have calculated the 1+ and 3+, T=0 states in 14N and 10B. In a
neutron-proton RPA model these two nuclei are described by the same set of
equations. We first show that a bare Minnesota interaction leads to too weak
binding in bothnuclei. Furthermore it does not produce a 3+ ground state in 10B
as it should. Including medium effects as an exchange of phonons between the
neutron-proton pair cures the desagreement in 14N but still gives a 1+ ground
state in 10B with the 3+ as an excited state. The same study with a Gogny
effective interaction reproduces nicely the properties of both nuclei: same
agreement in 14N as previously when medium effeccts were introduced but now the
3+ in 10B becomes the ground state. This success suggests that through its
density dependent term the Gogny interaction takes account of the presence of a
three-body force which, in a shell model calculation, has been shown to be
essential to give a 3+ ground state in 10B.
| nucl-th | we have calculated the 1 and 3 t0 states in 14n and 10b in a neutronproton rpa model these two nuclei are described by the same set of equations we first show that a bare minnesota interaction leads to too weak binding in bothnuclei furthermore it does not produce a 3 ground state in 10b as it should including medium effects as an exchange of phonons between the neutronproton pair cures the desagreement in 14n but still gives a 1 ground state in 10b with the 3 as an excited state the same study with a gogny effective interaction reproduces nicely the properties of both nuclei same agreement in 14n as previously when medium effeccts were introduced but now the 3 in 10b becomes the ground state this success suggests that through its density dependent term the gogny interaction takes account of the presence of a threebody force which in a shell model calculation has been shown to be essential to give a 3 ground state in 10b | [['we', 'have', 'calculated', 'the', '1', 'and', '3', 't0', 'states', 'in', '14n', 'and', '10b', 'in', 'a', 'neutronproton', 'rpa', 'model', 'these', 'two', 'nuclei', 'are', 'described', 'by', 'the', 'same', 'set', 'of', 'equations', 'we', 'first', 'show', 'that', 'a', 'bare', 'minnesota', 'interaction', 'leads', 'to', 'too', 'weak', 'binding', 'in', 'bothnuclei', 'furthermore', 'it', 'does', 'not', 'produce', 'a', '3', 'ground', 'state', 'in', '10b', 'as', 'it', 'should', 'including', 'medium', 'effects', 'as', 'an', 'exchange', 'of', 'phonons', 'between', 'the', 'neutronproton', 'pair', 'cures', 'the', 'desagreement', 'in', '14n', 'but', 'still', 'gives', 'a', '1', 'ground', 'state', 'in', '10b', 'with', 'the', '3', 'as', 'an', 'excited', 'state', 'the', 'same', 'study', 'with', 'a', 'gogny', 'effective', 'interaction', 'reproduces', 'nicely', 'the', 'properties', 'of', 'both', 'nuclei', 'same', 'agreement', 'in', '14n', 'as', 'previously', 'when', 'medium', 'effeccts', 'were', 'introduced', 'but', 'now', 'the', '3', 'in', '10b', 'becomes', 'the', 'ground', 'state', 'this', 'success', 'suggests', 'that', 'through', 'its', 'density', 'dependent', 'term', 'the', 'gogny', 'interaction', 'takes', 'account', 'of', 'the', 'presence', 'of', 'a', 'threebody', 'force', 'which', 'in', 'a', 'shell', 'model', 'calculation', 'has', 'been', 'shown', 'to', 'be', 'essential', 'to', 'give', 'a', '3', 'ground', 'state', 'in', '10b']] | [-0.08003010529897768, 0.17923811457673736, -0.09035880693770719, 0.10247286849330658, 0.03808820547790013, -0.11643337459783211, 0.018545533804872043, 0.3702559607724349, -0.1942567342327851, -0.30979525245951883, 0.002534712149733395, -0.32213384820656343, -0.055025829177942465, 0.10824210376506954, 0.057813114458412834, -0.0069293079788401496, 0.0603923647749153, 0.08547474382388773, -0.06437089233235879, -0.1954923442063966, 0.31396867110196386, 0.03808805055238984, 0.23637266681868244, 0.11963029510031144, 0.05705087772203666, 0.023941507422591022, 0.07918491748754274, -0.007919372982260855, -0.06906334312930773, 0.04838142028134881, 0.25842799511138403, 0.03104980455175268, 0.21947954783611226, -0.4563880018664129, -0.20171349483972528, 0.07877248413860798, 0.17547066803795822, 0.20406900555191732, -0.047085074191405014, -0.29457609411329033, 0.03840058965213371, -0.2576171626139319, -0.14688347346911376, -0.10585943668177633, 0.04626664534267603, 0.027194694388714254, -0.24518666723910648, 0.06563611005655151, 0.038501111972569065, -0.0015871755440126766, -0.1615558420900594, -0.1914235729949944, -0.02714638453343827, 0.12259021079587525, 0.05472606596903819, 0.07910334901235094, 0.10212191449845154, -0.14186918016128017, -0.045339576857672495, 0.40194108166703674, -0.06609318250451576, -0.16498583610818693, 0.16182622662886526, -0.14342295188724882, -0.10657997654581612, 0.16782403352218822, 0.0922551572449844, 0.07863126135233676, -0.15700101510552816, 0.07637946419916151, -0.022462691742729284, 0.2212224782134096, 0.022316667429086837, 0.023423221232819327, 0.11861462872334276, 0.1762686413331804, 0.025275211909672978, 0.09508577169159033, -0.11114799258101618, -0.09639600360709609, -0.2881024495896065, -0.12461789134099628, -0.16917612291237508, 0.047259533928908325, 0.0007112498820237251, -0.14611749124596826, 0.34640437612930935, 0.07919183150745195, 0.21699953411748124, -0.03689131701125227, 0.26583448199865717, 0.0712922630458541, 0.06536598918169285, 0.05763676669730833, 0.33036127907760215, 0.16683101803628783, 0.0569467468723429, -0.2518860509308676, 0.09415401937157819, 0.03466470090418377] |
711.3174 | Seminar on Records Theory | In quantum gravity, one seeks to combine quantum mechanics and general
relativity. In attempting to do so, one comes across the `problem of time'
impasse: the notion of time is conceptually different in each of these
theories. In this seminar, I consider the timeless records approach toward
resolving this. Records are localized, information-containing subconfigurations
of a single instant. Records theory is the study of these and of how science
(or history) is to be abstracted from correlations between them. I explain how
to motivate this approach, provide a ground-level structure for it and discuss
what kind of further tools are needed. For a more comprehensive account with
many more references, see [1].

711.3175 | Search for RS gravitons via $W_L W_L$ decays | The original Randall-Sundrum (RS) model with a warped extra dimension along
with extensions provides the possibility for a simultaneous solution to
Planck-weak hierarchy problem as well as the flavor puzzle in the Standard
Model (SM). The most distinctive feature of this scenario is the existence of
Kaluza-Klein (KK) gravitons whose masses and couplings to the SM fields are set
by the TeV scale. In some realistic versions of this framework, the largest
coupling of the gravitons to the observed particles is to the top quark and
unphysical Higgses ($W^{\pm}_L$ and $Z_L$) with the KK graviton (G) masses
predicted to be $\gsim$ 4 TeV. We extend earlier works on the KK graviton
decays to the $t\bar{t}$ final state and to the ``gold-plated'' $Z_L Z_L$ modes
(with each Z decaying to $e^+ e^-$ or to $\mu^+ \mu^-$) by studying the
resonant production of the gravitons and their subsequent decay to $W_L W_L$
pair. We find that with 300 $fb^{-1}$ integrated luminosity of data the
semileptonic $G \to W (\to l \nu_l) W(\to 2 jets)$ mode offers a good
opportunity to search for the RS KK graviton mode with mass lighter than $\sim$
3-3.5 TeV at the CERN LHC. Efficient WW mass reconstruction in the semileptonic
mode combined with an analysis of dilepton mass distribution in the purely
leptonic channel, $pp \to W (\to l \nu_l) W(\to l^\prime \nu_{l^\prime})$ may
help to observe KK $Z^\prime$ and KK graviton separately. Suitably defined
average energy of the charged lepton in the semileptonic mode may be used to
distinguish decays from longitudinal versus transverse W-bosons.

711.3176 | To Decode the Interference or To Consider it as Noise | We address single-user data transmission over a channel where the received
signal incurs interference from a finite number of users (interfering users)
that use single codebooks for transmitting their own messages. The receiver,
however, is allowed to decode interfering users' messages. This means the
signal transmitted from any interfering user is either decoded or considered as
noise at the receiver side. We propose the following method to obtain an
achievable rate for this channel. Assuming its own data is decoded
successfully, the receiver partitions the set of interfering users into two
disjoint subsets, namely the set of decodable users and the set of
non-decodable users. Then the transmitter's rate is chosen such that the
intended signal can be jointly decoded with the set of decodable users. To show
the strength of this method, we prove that for the additive Gaussian channel
with Gaussian interfering users, the Gaussian distribution is optimal and the
achievable rate is the capacity of this channel. To obtain the maximum
achievable rate, one needs to find the maximum decodable subset of interfering
users. Due to the large number of possible choices, having efficient algorithms
that find the set of decodable users with maximum cardinality is desired. To
this end, we propose an algorithm that enables the receiver to accomplish this
task in polynomial time.

711.3177 | Hopf algebroids and secondary characteristic classes | We study a Hopf algebroid, $\calh$, naturally associated to the groupoid
$U_n^\delta\ltimes U_n$. We show that classes in the Hopf cyclic cohomology of
$\calh$ can be used to define secondary characteristic classes of trivialized
flat $U_n$-bundles. For example, there is a cyclic class which corresponds to
the universal transgressed Chern character and which gives rise to the
continuous part of the $\rho$-invariant of Atiyah-Patodi-Singer. Moreover,
these cyclic classes are shown to extend to the K-theory of the associated
$C^{*}$-algebra. This point of view gives leads to homotopy invariance results
for certain characteristic numbers. In particular, we define a subgroup of the
cohomology of a group analogous to the Gelfand-Fuchs classes described by
Connes, \cite{connes:transverse}, and show that the higher signatures
associated to them are homotopy invariant.

effective mass model which is used to relate the FRET rate to measureable
quantities such as the nanocrystal size, fundamental gap, effective mass,
exciton radius and dielectric constant. We discuss the relative contribution to
the FRET rate of the different multipole terms, the role of strong to weak
confinement limits, and the effects of nanocrystal siz-es.

711.3179 | Beta Cephei stars in the ASAS-3 data. I. Long-term variations of periods
and amplitudes | We analysed V-filter ASAS-3 photometry of 41 known Beta Cephei-type stars.
The ASAS-3 photometry was combined with the archival data, if available, to
determine long-term stability of periods and amplitudes of excited modes. We
detected amplitude changes in three Beta Cephei stars, BW Cru, V836 Cen, and
V348 Nor. Period changes were found in KK Vel and V836 Cen. Our analysis shows
that intrinsic period changes are more common among multiperiodic stars,
apparently because they are caused by some kind of mode interaction. In
addition, we found new modes for seven stars, and for ten others we provide new
solutions or remove ambiguities in the detected frequencies. One candidate
hybrid Beta Cephei/SPB star, HD133823, is discovered.

711.318 | How strong is the evidence for accelerated expansion? | We test the present expansion of the universe using supernova type Ia data
without making any assumptions about the matter and energy content of the
universe or about the parameterization of the deceleration parameter. We assume
the cosmological principle to apply in a strict sense. The result strongly
depends on the data set, the light-curve fitting method and the calibration of
the absolute magnitude used for the test, indicating strong systematic errors.

are particularly important for the question of formation of X-ray binaries. We
present results of numerical simulations of 70 globular clusters with different
dynamical properties and a total stellar mass of 2*10^7 Msun. We find that in
order to retain enough neutron stars to match observations we must assume that
NSs can be formed via electron-capture supernovae. Our simulations explain the
observed dependence of the number of LMXBs on ``collision number'' as well as
the large scatter observed between different globular clusters. For millisecond
pulsars, we obtain good agreement between our models and the numbers and
characteristics of observed pulsars in the clusters Terzan 5 and 47 Tuc

711.3182 | XMM-Newton observations of the diffuse X-ray emission in the starburst
galaxy NGC 253 | Aims: We present a study of the diffuse X-ray emission in the halo and the
disc of the starburst galaxy NGC 253. Methods: After removing point-like
sources, we analysed XMM-Newton images, hardness ratio maps and spectra from
several regions in the halo and the disc. We introduce a method to produce
vignetting corrected images from the EPIC pn data, and we developed a procedure
that allows a correct background treatment for low surface brightness spectra,
using a local background, together with closed filter observations. Results:
Most of the emission from the halo is at energies below 1 keV. In the disc,
also emission at higher energies is present. The extent of the diffuse emission
along the major axis of the disc is 13.6 kpc. The halo resembles a horn
structure and reaches out to ~9 kpc perpendicular to the disc. Disc regions
that cover star forming regions, like spiral arms, show harder spectra than
regions with lower star forming activity. Models for spectral fits of the disc
regions need at least three components: two thermal plasmas with solar
abundances plus a power law and galactic foreground absorption. Temperatures
are between 0.1 and 0.3 keV and between 0.3 and 0.9 keV for the soft and the
hard component, respectively. The power law component may indicate an
unresolved contribution from X-ray binaries in the disc. The halo emission is
not uniform, neither spatially nor spectrally. The southeastern halo is softer
than the northwestern halo. To model the spectra in the halo, we needed two
thermal plasmas with solar abundances plus galactic foreground absorption.
Temperatures are around 0.1 and 0.3 keV. A comparison between X-ray and UV
emission shows that both originate from the same regions.

711.3185 | Chiral Dynamics and Single-Spin Asymmetries | Parity-conserving single-spin asymmetries provide a specific measure of
coherent spin-orbit dynamics in quantum chromodynamics. The origin of these
effects can be traced to the interplay of chiral dynamics and confinement in
the theory. The most elegant display of the relevant mechanisms occurs in the
Collins functions and the polarizing fragmentation functions and fracture
functions for particles with spin. In the nucleon, these same dynamical
mechanisms generate virtual quantum structures leading to the Boer-Mulders
functions and orbital distributions. Two complementary formalisms for these
distributions appear. The familiar gauge-link formalism incorporates oll
nonperturbative dynamics into nonlocal correlators. The constructive formalism
introduced by the author describes distributions normalized to an intrinsic
property of the nucleon, namely, the currents specified in the
Bakker-Leader-Trueman sum rule. The connection between these two approaches can
be explored in the process dependence of single-spin asymmetries in various
hard-scattering processes. The study of the SU(2) Weyl-Dirac equation in
spherical coordinates allows typical Wilson operators that determine this
process dependence to be evaluated in the coordinate gauge.

711.3186 | Beyond 1D: spectral line formation with 3D hydrodynamical model
atmospheres of red giants | We present the results of realistic, 3D, hydrodynamical, simulations of
surface convection in red giant stars with varying effective temperatures and
metallicities. We use the convection simulations as time-dependent,
hydrodynamical, model atmospheres to compute spectral line profiles for a
number of ions and molecules under the assumption of local thermodynamic
equilibrium (LTE). We compare the results with the predictions of line
formation calculations based on 1D, hydrostatic, model stellar atmospheres in
order to estimate the impact of 3D models on the derivation of elemental
abundances. We find large negative 3D-1D LTE abundance corrections (typically
-0.5 to -1 dex) for weak low-excitation lines from molecules and neutral
species in the very low metallicity cases. Finally, we discuss the extent of
departures from LTE in the case of neutral iron spectral line formation.

711.3187 | In defense of local textures (and other Higgs gradients) | Cruz et al. recently showed that the CMB cold spot can be explained by a
GUT-scale texture. But following Turok's argument that gauged configurations
always relax quickly, they posit a global symmetry, without obvious relation to
GUTs. An observation by Nambu invalidates Turok's argument when the broken
symmetry group has commuting generators. This is demonstrated explicitly in the
standard model of electroweak interactions and holds generally for intermediate
SSB stages in GUTs. The cold spot could therefore be due to a GUT texture, and
electroweak Higgs gradients may evolve indefinitely.

711.3188 | Local-gated single-walled carbon nanotube field effect transistors
assembled by AC dielectrophoresis | We present a simple and scalable technique for the fabrication of solution
processed & local gated carbon nanotube field effect transistors (CNT-FETs).
The approach is based on directed assembly of individual single wall carbon
nanotube from dichloroethane via AC dielectrophoresis (DEP) onto pre-patterned
source and drain electrodes with a local aluminum gate in the middle.
Local-gated CNT-FET devices display superior performance compared to global
back gate with on-off ratios 10^4 and maximum subthreshold swings of 170
mV/dec. The local bottom-gated DEP assembled CNT-FETs will facilitate large

711.3189 | Hindrance of ^{16}O+^{208}Pb fusion at extreme sub-barrier energies | We analyze the fusion data for $^{16}$O+$^{208}$Pb using coupled-channels
calculations. We include couplings to the low-lying surface excitations of the
projectile and target and study the effect of the ($^{16}$O,$^{17}$O)
one-neutron pickup. The hindrance of the fusion data that is observed at
energies far below the Coulomb barrier cannot be explained by a conventional
ion-ion potential and defining the fusion in terms of ingoing-wave boundary
conditions (IWBC). We show that the hindrance can be explained fairly well by
applying the M3Y double-folding potential which has been corrected with a
calibrated, repulsive term that simulates the effect of nuclear
incompressibility.
We show that the coupling to one-neutron transfer channels plays a crucial
role in improving the fit to the data. The best fit is achieved by increasing
the transfer strength by 25% relative to the strength that is required to
reproduce the one-neutron transfer data. The larger strength is not unrealistic
because the calculated inelastic plus transfer cross section is in good
agreement with the measured quasielastic cross section. We finally discuss the
problem of reproducing the fusion data at energies far above the Coulomb
barrier. Here we do not account for the data when we apply the IWBC but the
discrepancy is essentially eliminated by applying the M3Y+repulsion potential
and a weak, short-ranged imaginary potential.

711.319 | Three-dimensional dielectric photonic crystal structures for
laser-driven acceleration | We present the design and simulation of a three-dimensional photonic crystal
waveguide for linear laser-driven acceleration in vacuum. The structure
confines a synchronous speed-of-light accelerating mode in both transverse
dimensions. We report the properties of this mode, including sustainable
gradient and optical-to-beam efficiency. We present a novel method for
confining a particle beam using optical fields as focusing elements. This
technique, combined with careful structure design, is shown to have a large

711.3191 | The distribution of polynomials over finite fields, with applications to
the Gowers norms | In this paper we investigate the uniform distribution properties of
polynomials in many variables and bounded degree over a fixed finite field F of
prime order. Our main result is that a polynomial P : F^n -> F is
poorly-distributed only if P is determined by the values of a few polynomials
of lower degree, in which case we say that P has small rank.
We give several applications of this result, paying particular attention to
consequences for the theory of the so-called Gowers norms. We establish an
inverse result for the Gowers U^{d+1}-norm of functions of the form f(x)=
e_F(P(x)), where P : F^n -> F is a polynomial of degree less than F, showing
that this norm can only be large if f correlates with e_F(Q(x)) for some
polynomial Q : F^n -> F of degree at most d.
The requirement deg(P) < |F| cannot be dropped entirely. Indeed, we show the
above claim fails in characteristic 2 when d = 3 and deg(P)=4, showing that the
quartic symmetric polynomial S_4 in F_2^n has large Gowers U^4-norm but does
not correlate strongly with any cubic polynomial. This shows that the theory of
Gowers norms in low characteristic is not as simple as previously supposed.
This counterexample has also been discovered independently by Lovett, Meshulam,
and Samorodnitsky.
We conclude with sundry other applications of our main result, including a
recurrence result and a certain type of nullstellensatz.

711.3192 | Sum rule for the double virtual Compton scattering | The two photon exchange amplitude is investigated in frame of analytic
properties of the virtual Compton scattering amplitude as a function of the
invariant mass squared of the intermediate hadronic state. A sum rule is built,
based on arguments from analyticity. It relates the differential cross section
of elastic electron-proton scattering including form factors, and the cross
section of inelastic scattering channel, with a contribution of nucleon

711.3193 | Models and Phenomenology of Maximal Flavor Violation | We consider models of maximal flavor violation (MxFV), in which a new scalar
mediates large q_3 <-> q_1 or q_3 <-> q_2 flavor changing transitions (q_i is
an i'th generation quark), while q_3 <-> q_3 transitions are suppressed, e.g.,
\xi_{31}, \xi_{13} ~ V_{tb} and \xi_{33} ~ V_{td}, where \xi_{ij} are the new
scalar couplings to quarks and V is the CKM matrix. We show that, contrary to
the conventional viewpoint, such models are not ruled out by the existing low
energy data on K^0, B^0 and D^0 oscillations and rare K and B-decays. We also
show that these models of MxFV can have surprising new signatures at the LHC
and the Tevatron.

711.3194 | Negative specific heat for quasi-2D vortex structures in electron
plasmas: an explicit, closed-form derivation | Negative specific heat is a dramatic phenomenon where processes decrease in
temperature when adding energy. It has been observed in gravo-thermal collapse
of globular clusters. We now report finding this phenomenon in bundles of
nearly parallel, periodic, single-sign generalized vortex filaments in the
electron magnetohydrodynamic (EMH) model for the unbounded plane under strong
magnetic confinement. We derive the specific heat using a steepest descent
method and a mean field property. Our derivations show that as temperature
increases, the overall size of the system increases exponentially and the
energy drops. The implication of negative specific heat is a runaway reaction,
resulting in a collapsing inner core surrounded by an expanding halo of
filaments.

arXiv:0711.3093v1, by A. Rosch | We reply to the Comment by Achim Rosch [1] (arXiv:0711.3093v1) who challenges
our finding in Ref. [2] (arXiv:0711.0952v1) with regard to the validity of the
Luttinger theorem in the cases of Mott insulating N-particle ground states
(even) when the chemical potential used in applying this theorem coincides with
the zero-temperature limit of the chemical potential satisfying the equation of
state corresponding to N particles. Rosch further argues that the
strong-coupling expression for the single-particle Green function presented in
Ref. [3] (arXiv:cond-mat/0602656v2) and analyzed in Ref. [2] does not imply
destruction of the Mott insulating state at half-filling as a result of an
arbitrary weak hopping contribution that breaks particle-hole symmetry and
therefore suggests that our conclusion in Ref. [2] to the contrary were
incorrect. Here we show the shortcomings of Rosch's arguments.

711.3196 | Upper Limits from HESS AGN Observations in 2005-2007 | AIMS: Very high energy (VHE; E>100 GeV) gamma-ray studies were performed for
18 active galactic nuclei (AGN) from a variety of AGN classes.
METHODS: VHE observations of a sample of 14 AGN, considered candidate VHE
emitters, were made with the High Energy Stereoscopic System (HESS) between
January 2005 and July 2007. Large-zenith-angle observations of three northern
AGN (Mkn 421, Mkn 501, 1ES 1218+304), known to emit VHE gamma rays, were also
performed in order to sample their spectral energy distributions (SEDs) above 1
TeV. In addition, the VHE flux from 1ES 1101-232, previously detected by HESS
in 2004-2005, was monitored during 2006 and 2007.
RESULTS: As significant detections from the HESS observation program are
reported elsewhere, the results reported here are primarily integral flux upper
limits. The average exposure for each of the 14 VHE-candidate AGN is ~7 h live
time, and the observations have an average energy threshold between 230 GeV and
590 GeV. Upper limits for these 14 AGN range from <0.9% to <4.9% of the Crab
Nebula flux, and eight of these are the most constraining ever reported for the
object. The brief (<2.2 h each) large-zenith-angle observations yield upper
limits for Mkn 501 (<20% Crab above 2.5 TeV) and 1ES 1218+304 (<17% Crab above
1.0 TeV), and a marginal detection (3.5 sigma) of Mkn 421 (50% Crab above 2.1
TeV). 1ES 1101-232 was marginally detected (3.6 sigma, 1.7% Crab above 260 GeV)
during the 2006 (13.7 h live time) observations, but not in the 2007 (4.6 h
live time) data. The upper limit in 2007 (<1.9% Crab above 260 GeV) is below
the average flux measured by HESS from 2004-2006.

711.3199 | Analyzing and Modeling Real-World Phenomena with Complex Networks: A
Survey of Applications | The success of new scientific areas can be assessed by their potential for
contributing to new theoretical approaches and in applications to real-world
problems. Complex networks have fared extremely well in both of these aspects,
with their sound theoretical basis developed over the years and with a variety
of applications. In this survey, we analyze the applications of complex
networks to real-world problems and data, with emphasis in representation,
analysis and modeling, after an introduction to the main concepts and models. A
diversity of phenomena are surveyed, which may be classified into no less than
22 areas, providing a clear indication of the impact of the field of complex
networks.

711.32 | Towards a theory of classification | The well-known difficulties arising in a classification which is not
set-theoretically trivial---involving what is sometimes called a non-smooth
quotient---have been overcome in a striking way in the theory of operator
algebras by the use of what might be called a classification functor---the very
existence of which is already a surprise. Here the notion of such a functor is

is controlled solely by the disorder strength and the ratio between the sample

factor is shown to have a narrow dip near the neutrality point for weak
disorder and to develop a nearly doping independent behavior at strong

of the two-color (laser plus x rays) rotational-electronic problem. The
interaction with the laser is assumed to be nonresonant; it is described by an
electric dipole polarizability tensor. X-ray absorption is approximated as a
one-photon process. It is shown that the equations can be separated such that
the interaction with the laser can be treated independently of the x rays. The
laser-only density matrix is propagated numerically. After each time step, the
x-ray absorption is calculated. We apply our theory to study adiabatic
alignment of bromine molecules (Br2). The required dynamic polarizabilities are
determined using the ab initio linear response methods coupled-cluster singles
(CCS), second-order approximate coupled-cluster singles and doubles (CC2), and
coupled-cluster singles and doubles (CCSD). For the description of x-ray
absorption on the sigma_g 1s --> sigma_u 4p resonance, a parameter-free
two-level model is used for the electronic structure of the molecules. Our
theory opens up novel perspectives for the quantum control of x-ray radiation.

711.3204 | Fractional Quantum Hall Hierarchy and the Second Landau Level | We generalize the fractional quantum Hall hierarchy picture to apply to
arbitrary, possibly non-Abelian, fractional quantum Hall states. Applying this
to the nu = 5/2 Moore-Read state, we construct new explicit trial wavefunctions
to describe the fractional quantum Hall effect in the second Landau level. The
resulting hierarchy of states, which reproduces the filling fractions of all
observed Hall conductance plateaus in the second Landau level, is characterized
by electron pairing in the ground state and an excitation spectrum that
includes non-Abelian anyons of the Ising type. We propose this as a unifying
picture in which p-wave pairing characterizes the fractional quantum Hall
effect in the second Landau level.

711.3205 | Relay Subset Selection in Wireless Networks Using Partial
Decode-and-Forward Transmission | This paper considers the problem of selecting a subset of nodes in a two-hop
wireless network to act as relays in aiding the communication between the
source-destination pair. Optimal relay subset selection with the objective of
maximizing the overall throughput is a difficult problem that depends on
multiple factors including node locations, queue lengths and power consumption.
A partial decode-and-forward strategy is applied in this paper to improve the
tractability of the relay selection problem and performance of the overall
network.
Note that the number of relays selected ultimately determines the performance
of the network. This paper benchmarks this performance by determining the net
diversity achieved using the relays selected and the partial decode-and-forward
strategy. This framework is subsequently used to further transform relay
selection into a simpler relay placement problem, and two proximity-based
approximation algorithms are developed to determine the appropriate set of
relays to be selected in the network. Other selection strategies such as random
relay selection and a greedy algorithm that relies on channel state information
are also presented. This paper concludes by showing that the proposed
proximity-based relay selection strategies yield near-optimal expected rates
for a small number of selected relays.

711.3206 | Shot Noise in Graphene | We report measurements of current noise in single- and multi-layer graphene
devices. In four single-layer devices, including a p-n junction, the Fano
factor remains constant to within +/-10% upon varying carrier type and density,
and averages between 0.35 and 0.38. The Fano factor in a multi-layer device is
found to decrease from a maximal value of 0.33 at the charge-neutrality point
to 0.25 at high carrier density. These results are compared to theoretical
predictions for shot noise in ballistic and disordered graphene.
