710.0453 | Higher-spin Gauge and Trace Anomalies in Two-dimensional Backgrounds | Two-dimensional quantum fields in electric and gravitational backgrounds can
be described by conformal field theories, and hence all the physical
(covariant) quantities can be written in terms of the corresponding holomorphic
quantities. In this paper, we first derive relations between covariant and
holomorphic forms of higher-spin currents in these backgrounds, and then, by
using these relations, obtain higher-spin generalizations of the trace and
gauge (or gravitational) anomalies up to spin 4. These results are applied to
derive higher-moments of Hawking fluxes in black holes in a separate paper

710.0454 | Search for two photon exchange from $e^+ +e^-\to p+\bar p +\gamma$ data | We look for asymmetries in the angular distributions of events from recent
data on $e^+ +e^-\to p +\bar p +\gamma$ from BABAR collaboration. From first
principles, as the C-invariance of the electromagnetic interaction and the
crossing symmetry, the presence of two-photon exchange would create a forward
backward asymmetry in the data. The analysis of the available data shows no
asymmetry, within an error of 2%. This result is consistent with a
structureless model for the proton, based on a calculation of $e^+ +e^-\to
\mu^+ + \mu^- +\gamma$ with a proper replacement of the muon mass. As no
systematic deviations are seen, we can conclude that these data do not give any
hint of the presence of the two photon contribution, in all the considered
kinematical range.

710.0455 | Adjoint zero-modes as a tool to understand the Yang-Mills vacuum | The use of adjoint (quasi) zero-modes of the Dirac operator to probe the
Yangs-Mills vacuum has been recently advocated by Gonzalez-Arroyo and Kirchner.
The construction relies on the use of the super-symmetric zero mode which, for
classical configurations, provides a direct estimate of the gauge action
density. In the lattice implementation of this idea, we show how the results
improve considerably if the overlap operator is used instead of the
Wilson-Dirac one. Before proceeding to the detailed study of Monte Carlo
ensembles, we studied here a series of potentially complicated situations which
can be encountered. In particular, we study the case of instanton
anti-instanton pairs and analyse how the results depend upon separation. The
effect of lattice artifacts is also of concern. Indeed, a statistical analysis
of zero modes of thermalised SU(2) configurations at beta=2.57 shows a
significant fraction having 4N+2 adjoint zero modes, in contradiction with the
index theorem. This violation must be associated to the roughness of the

710.0458 | An alternative heavy Higgs mass limit | After commenting on the present value of the Higgs particle mass from
radiative corrections, we explore the phenomenological implications of an
alternative, non-perturbative renormalization of the scalar sector where the
mass of the Higgs particle does not represent a measure of observable
interactions at the Higgs mass scale. In this approach the Higgs particle could

710.0459 | Statistical properties of agent-based market area model | One dimensional stylized model taking into account spatial activity of firms
with uniformly distributed customers is proposed. The spatial selling area of
each firm is defined by a short interval cut out from selling space (large
interval). In this representation, the firm size is directly associated with
the size of its selling interval.
The recursive synchronous dynamics of economic evolution is discussed where
the growth rate is proportional to the firm size incremented by the term
including the overlap of the selling area with areas of competing firms. Other
words, the overlap of selling areas inherently generate a negative feedback
originated from the pattern of demand. Numerical simulations focused on the
obtaining of the firm size distributions uncovered that the range of free
parameters where the Pareto's law holds corresponds to the range for which the
pair correlation between the nearest neighbor firms attains its minimum.

tree is the scaling limit of the simple random walks on any family of discrete

typical realisations of the trees) and an annealed version (averaged over all

cover the important example of simple random walks on the trees generated by
the Galton-Watson branching process, conditioned on the total population size.

710.0461 | Momentum of an electromagnetic wave in dielectric media | Almost a hundred years ago, two different expressions were proposed for the
energy--momentum tensor of an electromagnetic wave in a dielectric. Minkowski's
tensor predicted an increase in the linear momentum of the wave on entering a
dielectric medium, whereas Abraham's tensor predicted its decrease. Theoretical
arguments were advanced in favour of both sides, and experiments proved
incapable of distinguishing between the two. Yet more forms were proposed, each
with their advocates who considered the form that they were proposing to be the
one true tensor. This paper reviews the debate and its eventual conclusion:
that no electromagnetic wave energy--momentum tensor is complete on its own.
When the appropriate accompanying energy--momentum tensor for the material
medium is also considered, experimental predictions of all the various proposed
tensors will always be the same, and the preferred form is therefore
effectively a matter of personal choice.

710.0463 | Ground-state phase diagram and magnetic properties of a tetramerized
spin-1/2 J_1-J_2 model: BEC of bound magnons and absence of the transverse
magnetization | We study the ground state and the magnetization process of a spin-1/2
$J_1$-$J_2$ model with a plaquette structure by using various methods. For
small inter-plaquette interaction, this model is expected to have a spin-gap
and we computed the first- and the second excitation energies. If the gap of
the lowest excitation closes, the corresponding particle condenses to form
magnetic orders. By analyzing the quintet gap and magnetic interactions among
the quintet excitations, we find a spin-nematic phase around $J_1/J_2\sim -2$
due to the strong frustration and the quantum effect. When high magnetic moment
is applied, not the spin-1 excitations but the spin-2 ones soften and dictate
the magnetization process. We apply a mean-field approximation to the effective
Hamiltonian to find three different types of phases (a conventional BEC phase,
``striped'' supersolid phases and a 1/2-plateau). Unlike the BEC in spin-dimer
systems, this BEC phase is not accompanied by transverse magnetization.

710.0465 | The Loudest Event Statistic: General Formulation, Properties and
Applications | The use of the loudest observed event to generate statistical statements
about rate and strength has become standard in searches for gravitational waves
from compact binaries and pulsars. The Bayesian formulation of the method is
generalized in this paper to allow for uncertainties both in the background
estimate and in the properties of the population being constrained. The method
is also extended to allow rate interval construction. Finally, it is shown how
to combine the results from multiple experiments and a comparison is drawn
between the upper limit obtained in a single search and the upper limit
obtained by combining the results of two experiments each of half the original
duration. To illustrate this, we look at an example case, motivated by the
search for gravitational waves from binary inspiral.

710.0467 | Inelastically generated solitons and anti-solitons in the perturbed KdV
equation | Under the effect of common perturbations, the multiple-soliton solution of
the KdV equation is transformed into a sum of an elastic and a first-order
inelastic component. The elastic component is a perturbation series, identical
in structure to the perturbed single-soliton solution. It preserves the
soliton-scattering picture. The inelastic component is generated by
perturbation terms that represent coupling between KdV solitons and
inelastically generated soliton-anti-soliton waves. It asymptotes into solitons
and anti-solitons, that evolve along the characteristic lines of the KdV
solitons. This is demonstrated in the two-soliton case.

710.0469 | Microscopic thickness determination of thin graphite films formed on SiC
from quantized oscillation in reflectivity of low-energy electrons | Low-energy electron microscopy (LEEM) was used to measure the reflectivity of
low-energy electrons from graphitized SiC(0001). The reflectivity shows
distinct quantized oscillations as a function of the electron energy and
graphite thickness. Conduction bands in thin graphite films form discrete
energy levels whose wave vectors are normal to the surface. Resonance of the
incident electrons with these quantized conduction band states enhances
electrons to transmit through the film into the SiC substrate, resulting in
dips in the reflectivity. The dip positions are well explained using
tight-binding and first-principles calculations. The graphite thickness

710.0472 | Ernst equation and spheroidal coordinates with a cosmological constant
term | We discuss solution generating techniques treating stationary and axially
symmetric metrics in the presence of a cosmological constant. Using the
recently found extended form of Ernst's complex equation, which takes into
account the cosmological constant term, we propose an extension of spheroidal
coordinates adapted to asymptotically de-Sitter and anti de-Sitter static
spacetimes. In the absence of a cosmological constant we show in addition that
any higher dimensional metric parametrised by a single angular momentum can be
given by a 4 dimensional solution and Weyl potentials parametrising the extra
Killing directions. We explicitly show how a stationary, and a static axially

710.0475 | DFT-based calculation of Coulomb blockade in molecular junction | Quantum transport through single molecules is very sensitive to the strength
of the molecule-electrode contact. When a molecular junction weakly coupled to
external electrodes, charging effects do play an important role (Coulomb
blockade regime). In this regime, the non-equilibrium Green function is usually
substituted with master equation approaches, which prevents the density
functional theory from describing Coulomb blockade in non-equilibrium case.
Last year, we proposed an Ansatz to combine the non-equilibrium Green function
technique with the equation of motion method. With help of it, Coulomb blockade
was obtained by non-equilibrium Green function, and completely agrees with the
master equation results [Phys. Rev. B \textbf{76}, 045408 (2007)]. Here, by the
Ansatz, we show a new way to introduce Coulomb blockade correction to DFT

710.0478 | Nonperturbative approach to the quantum Hall bilayer | We develop a nonperturbative approach to the quantum Hall bilayer (QHB) at
\nu=1 using trial wave functions. We predict phases of the QHB for arbitrary
distance d and, our approach, in a dual picture, naturally introduces a new
kind of quasiparticles - neutral fermions. Neutral fermion is a composite of
two merons of the same vorticity and opposite charge. For small d (i.e. in the
superfluid phase), neutral fermions appear as dipoles. At larger d dipoles
dissociate into the phase of the two decoupled Fermi-liquid-like states. This
scenario is relevant for the experimental situation where impurities lock
charged merons. In a translation invariant (clean) system, continuous creation
and annihilation of meron-antimeron pairs evolves the QHB toward a paired
phase. The quantum fluctuations fix the form of the pairing function to
g(z)=1/z^*. A part of the description of the paired phase is the 2D

comparison | We systematically compare three filtering methods used to extract topological
excitations from lattice gauge configurations, namely smearing, Laplace
filtering and the filtered fermionic topological charge (with chirally improved
fermions). Each of these techniques introduces ambiguities, like its parameter
dependence. We show, however, that all these methods can be tuned to each other
over a broad range of filtering levels and that they reveal very similar
topological structures. For these common structures we find an interesting
power-law relating the number and packing fraction of clusters of filtered

studying the role of the centre of the group for colour confinement in
Yang-Mills gauge theories. In this paper, we investigate $G_2$ pure gauge
theory at finite temperature on the lattice. By studying the finite size
scaling of the plaquette, the Polyakov loop and their susceptibilities, we show
that a deconfinement phase transition takes place. The analysis of the
pseudocritical exponents give strong evidence of the deconfinement transition
being first order. Implications of our findings for scenarios of colour

710.0482 | Conserving GW scheme for nonequilibrium quantum transport in molecular
contacts | We give a detailed presentation of our recent scheme to include correlation
effects in molecular transport calculations using the GW approximation within
the non-equilibrium Keldysh formalism. We restrict the GW self-energy to the
central region, and describe the leads by density functional theory (DFT). A
minimal basis of maximally localized Wannier functions is applied both in the
central GW region and the leads. The importance of using a conserving, i.e.
fully self-consistent, GW self-energy is demonstrated both analytically and by
numerical examples. We introduce an effective spin-dependent interaction which
automatically reduces self-interaction errors to all orders in the interaction.
The scheme is applied to the Anderson model in- and out of equilibrium. In
equilibrium at zero temperature we find that GW describes the Kondo resonance
fairly well for intermediate interaction strengths. Out of equilibrium we
demonstrate that the one-shot G0W0 approximation can produce severe errors, in
particular at high bias. Finally, we consider a benzene molecule between
featureless leads. It is found that the molecule's HOMO-LUMO gap as calculated
in GW is significantly reduced as the coupling to the leads is increased,
reflecting the more efficient screening in the strongly coupled junction. For
the IV characteristics of the junction we find that HF and G0W0[G_HF] yield
results closer to GW than does DFT and G0W0[G_DFT]. This is explained in terms
of self-interaction effects and life-time reduction due to electron-electron
interactions.

show how techniques based on the method of moving frames and exterior

710.0487 | Lattice supersymmetry in 1D with two supercharges | A consistent formulation of a fully supersymmetric theory on the lattice has
been a long standing challenge. In recent years there has been a renewed
interest on this problem with different approaches. At the basis of the
formulation we present in the following there is the Dirac-Kahler twisting
procedure, which was proposed in the continuum for a number of theories,
including N=4 SUSY in four dimensions. Following the formalism developed in
recent papers, an exact supersymmetric theory with two supercharges on a one
dimensional lattice is realized using a matrix-based model. The matrix
structure is obtained from the shift and clock matrices used in two dimensional
non-commutative field theories. The matrix structure reproduces on a one
dimensional lattice the expected modified Leibniz rule. Recent claims of
inconsistency of the formalism are discussed and shown not to be relevant.

710.0488 | On the ratio of string tensions in the 3D Z_4 lattice gauge theory | It was recently pointed out that simple scaling properties of Polyakov
correlation functions of gauge systems in the confining phase suggest that the
ratios of k-string tensions in the low temperature region is constant up to
terms of order T^3. Here we argue that, at least in a three-dimensional Z_4
gauge model, the above ratios are constant in the whole confining phase. This
result is obtained by combining numerical experiments with known exact results

710.0491 | Analysis of Linear Difference Schemes in the Sparse Grid Combination
Technique | Sparse grids are tailored to the approximation of smooth high-dimensional
functions. On a $d$-dimensional tensor product space, the number of grid points
is $N = \mathcal O(h^{-1} |\log h|^{d-1})$, where $h$ is a mesh parameter. The
so-called combination technique, based on hierarchical decomposition and
extrapolation, requires specific multivariate error expansions of the
discretisation error on Cartesian grids to hold. We derive such error
expansions for linear difference schemes through an error correction technique
of semi-discretisations. We obtain overall error formulae of the type $\epsilon
= \mathcal{O} (h^p |\log h|^{d-1})$ and analyse the convergence, with its

710.0493 | Planar trees, free nonassociative algebras, invariants, and elliptic
integrals | We consider absolutely free nonassociative algebras and, more generally,
absolutely free algebras with (maybe infinitely) many multilinear operations.
Such algebras are described in terms of labeled reduced planar rooted trees.
This allows to apply combinatorial techniques to study their Hilbert series and
the asymptotics of their coefficients. These algebras satisfy the
Nielsen-Schreier property and their subalgebras are also free. Then, over a
field of characteristic 0, we investigate the subalgebras of invariants under
the action of a linear group, their sets of free generators and their Hilbert
series. It has turned out that, except in the trivial cases, the algebra of
invariants is never finitely generated. In important partial cases the Hilbert
series of the algebras of invariants and the generating functions of their sets
of free generators are expressed in terms of elliptic integrals.

710.0494 | The z=0.8 precursors of today's bulges | We study the color structure of disk galaxies in the Groth strip at redshifts
0.1<z<1.2. Our aim is to test formation models in which bulges form
before/after the disk. We find smooth color distributions with gentle outward
blueing across the galaxy image: bulges are not distinctly redder than their
disks; and bulge colors strongly correlate with global colors. The results
suggest a roughly coeval evolution of bulges and disks. About 50% of the nuclei
of galaxies with central light excesses above the outer exponential profile
hold passively evolving red populations. The remainder 50% are galaxies with

710.0496 | Microscopic mechanisms of spin-dependent electric polarization in 3d
oxides | We address a systematic microscopic theory of spin-dependent electric
polarization in 3d oxides starting with a generic three-site two-hole cluster.
A perturbation scheme realistic for 3d oxides is applied which implies the
quenching of orbital moments by low-symmetry crystal field, strong intra-atomic
correlations, the dp-transfer effects, and rather small spin-orbital coupling.
An effective spin operator of the electric dipole moment is deduced
incorporating both nonrelativistic and relativistic terms. The nonrelativistic
electronic polarization mechanism related with the effects of the
redistribution of the local on-site charge density due to $pd$ covalency and
exchange coupling is believed to govern the multiferroic behaviour in 3d
oxides. The relativistic exchange-dipole moment is mainly stems from the
nonrelativistic one due to the perturbation effect of Dzyaloshinsky-Moriya

710.0497 | A Joint Search for Gravitational Wave Bursts with AURIGA and LIGO | The first simultaneous operation of the AURIGA detector and the LIGO
observatory was an opportunity to explore real data, joint analysis methods
between two very different types of gravitational wave detectors: resonant bars
and interferometers. This paper describes a coincident gravitational wave burst
search, where data from the LIGO interferometers are cross-correlated at the
time of AURIGA candidate events to identify coherent transients. The analysis
pipeline is tuned with two thresholds, on the signal-to-noise ratio of AURIGA
candidate events and on the significance of the cross-correlation test in LIGO.
The false alarm rate is estimated by introducing time shifts between data sets
and the network detection efficiency is measured with simulated signals with
power in the narrower AURIGA band. In the absence of a detection, we discuss
how to set an upper limit on the rate of gravitational waves and to interpret
it according to different source models. Due to the short amount of analyzed
data and to the high rate of non-Gaussian transients in the detectors noise at
the time, the relevance of this study is methodological: this was the first
joint search for gravitational wave bursts among detectors with such different
spectral sensitivity and the first opportunity for the resonant and
interferometric communities to unify languages and techniques in the pursuit of
their common goal.

710.0498 | Screening at finite temperature and density | We present lattice QCD results on heavy quark free energies, extract from its
temperature dependence entropy and internal energy contributions, and discuss
the onset of medium effects that lead to screening of static quark-antiquark
sources in a thermal medium. Most results are obtained in (2+1)-flavour QCD on
a line of constant physics with almost realistic quark masses and compared to
previous results from 2-flavor QCD as well as pure gauge theory. Furthermore,
we discuss results on the density dependence of screening masses that have been

710.0499 | A silicate disk in the heart of the Ant | We aim at getting high spatial resolution information on the dusty core of
bipolar planetary nebulae to directly constrain the shaping process. Methods:
We present observations of the dusty core of the extreme bipolar planetary
nebula Menzel 3 (Mz 3, Hen 2-154, the Ant) taken with the mid-infrared
interferometer MIDI/VLTI and the adaptive optics NACO/VLT. The core of Mz 3 is
clearly resolved with MIDI in the interferometric mode, whereas it is
unresolved from the Ks to the N bands with single dish 8.2 m observations on a
scale ranging from 60 to 250 mas. A striking dependence of the dust core size
with the PA angle of the baselines is observed, that is highly suggestive of an
edge-on disk whose major axis is perpendicular to the axis of the bipolar
lobes. The MIDI spectrum and the visibilities of Mz 3 exhibit a clear signature
of amorphous silicate, in contrast to the signatures of crystalline silicates
detected in binary post-AGB systems, suggesting that the disk might be
relatively young. We used radiative-transfer Monte Carlo simulations of a
passive disk to constrain its geometrical and physical parameters. Its
inclination (74 degrees $\pm$ 3 degrees) and position angle (5 degrees $\pm$ 5
degrees) are in accordance with the values derived from the study of the lobes.
The inner radius is 9$\pm$ 1 AU and the disk is relatively flat. The dust mass
stored in the disk, estimated as 1 x 10-5Msun, represents only a small fraction
of the dust mass found in the lobes and might be a kind of relic of an
essentially polar ejection process.

710.05 | Infrared problem and spatially local observables in electrodynamics | An algebra previously proposed as an asymptotic field structure in
electrodynamics is considered in respect of localization properties of fields.
Fields are 'spatially local' -- localized in regions resulting as unions of two
intersecting (solid) lightcones: a future- and a past-lightcone. This
localization remains in concord with the usual idealizations connected with the
scattering theory. Fields thus localized naturally include infrared
characteristics normally placed at spacelike infinity and form a structure

A(2)-affine Toda field theory at the self-dual point. The latter is an
integrable model consisting of a pair of particles which are conjugated to each
other and possessing two bound states resulting from the scattering processes 1
+1 -> 2 and 2+2-> 1. We obtain solutions up to four particle form factors for
two families of fields which can be identified with spinless and spin-1 fields
of the bulk theory. Previously known as well as new bulk form factor solutions
are obtained as a particular limit of ours. Minimal solutions of the boundary
form factor equations for all A(n)-affine Toda field theories are given, which
will serve as starting point for a generalisation of our results to higher rank
algebras.

710.0502 | Dynamical resonances and SSF singularities for a magnetic Schroedinger
operator | We consider the Hamiltonian $H$ of a 3D spinless non-relativistic quantum
particle subject to parallel constant magnetic and non-constant electric field.
The operator $H$ has infinitely many eigenvalues of infinite multiplicity
embedded in its continuous spectrum. We perturb $H$ by appropriate scalar
potentials $V$ and investigate the transformation of these embedded eigenvalues
into resonances. First, we assume that the electric potentials are
dilation-analytic with respect to the variable along the magnetic field, and
obtain an asymptotic expansion of the resonances as the coupling constant
$\varkappa$ of the perturbation tends to zero. Further, under the assumption
that the Fermi Golden Rule holds true, we deduce estimates for the time
evolution of the resonance states with and without analyticity assumptions; in
the second case we obtain these results as a corollary of suitable Mourre
estimates and a recent article of Cattaneo, Graf and Hunziker \cite{cgh}. Next,
we describe sets of perturbations $V$ for which the Fermi Golden Rule is valid
at each embedded eigenvalue of $H$; these sets turn out to be dense in various
suitable topologies. Finally, we assume that $V$ decays fast enough at infinity
and is of definite sign, introduce the Krein spectral shift function for the
operator pair $(H+V, H)$, and study its singularities at the energies which
coincide with eigenvalues of infinite multiplicity of the unperturbed operator
$H$.

710.0503 | Unified Approach to the Large-Signal and High-Frequency Theory of
$p-n$-Junctions | Spectral approach to the charge carrier transport in $p-n$-junctions has
allowed us to revise the theoretical results relating to large signal operation
of the junction to make them valid for both the low and high frequencies
ranges. The spectral composition of the external circuit current includes both
the DC and AC components. The former produces the static current--voltage
characteristic with the modified Bessel function of zeroth order, $I_0(\beta
V_\sim)$, while the latter yields the dynamic admittance with the modified
Bessel function of first order, $I_1(\beta V_\sim)$, either of them depend on
the signal amplitude. Our experimental results are consistent with the
theoretical ones if a fitting parameter allowing for recombination processes in
the depletion layer is taken into account.

a subsequent Fourier-transform of its solution, the spectral function of heavy

710.0506 | Spitzer View of Lyman Break Galaxies | Using a combination of deep MID-IR observations obtained by IRAC, MIPS and
IRS on board Spitzer we investigate the MID-IR properties of Lyman Break
Galaxies (LBGs) at z~3, establish a better understanding of their nature and
attempt a complete characterisation of the population. With deep mid-infrared
and optical observations of ~1000 LBGs covered by IRAC/MIPS and from the ground
respectively, we extend the spectral energy distributions (SEDs) of the LBGs to
mid-infrared. Spitzer data reveal for the first time that the mid-infrared
properties of the population are inhomogeneous ranging from those with marginal
IRAC detections to those with bright rest-frame near-infrared colors and those
detected at 24mu MIPS band revealing the newly discovered population of the
Infrared Luminous Lyman Break Galaxies (ILLBGs). To investigate this diversity,
we examine the photometric properties of the population and we use stellar
population synthesis models to probe the stellar content of these galaxies. We
find that a fraction of LBGs have very red colors and large estimated stellar
masses M* > 5x10^10Mo. We discuss the link between these LBGs and
submm-luminous galaxies and we report the detection of rest frame 6.2 and 7.7mu
emission features arising from Polycyclic Aromatic Hydrocarbons (PAH) in the
Spitzer/IRS spectrum of an infrared-luminous Lyman break galaxy at z=3.01.

710.0507 | Results related to generalizations of Hilbert's non-immersibility
theorem for the hyperbolic plane | We discuss generalizations of the well-known theorem of Hilbert that there is
no complete isometric immersion of the hyperbolic plane into Euclidean 3-space.
We show that this problem is expressed very naturally as the question of the
existence of certain homotheties of reflective submanifolds of a symmetric
space. As such, we conclude that the only other (non-compact) cases to which
this theorem could generalize are the problem of isometric immersions with flat
normal bundle of the hyperbolic space $H^n$ into a Euclidean space $E^{n+k}$,
$n \geq 2$, and the problem of Lagrangian isometric immersions of $H^n$ into
$\cc^n$, $n \geq 2$. Moreover, there are natural compact counterparts to these

710.0508 | Structured variable selection in support vector machines | When applying the support vector machine (SVM) to high-dimensional
classification problems, we often impose a sparse structure in the SVM to
eliminate the influences of the irrelevant predictors. The lasso and other
variable selection techniques have been successfully used in the SVM to perform
automatic variable selection. In some problems, there is a natural hierarchical
structure among the variables. Thus, in order to have an interpretable SVM
classifier, it is important to respect the heredity principle when enforcing
the sparsity in the SVM. Many variable selection methods, however, do not
respect the heredity principle. In this paper we enforce both sparsity and the
heredity principle in the SVM by using the so-called structured variable
selection (SVS) framework originally proposed in Yuan, Joseph and Zou (2007).
We minimize the empirical hinge loss under a set of linear inequality
constraints and a lasso-type penalty. The solution always obeys the desired
heredity principle and enjoys sparsity. The new SVM classifier can be
efficiently fitted, because the optimization problem is a linear program.
Another contribution of this work is to present a nonparametric extension of
the SVS framework, and we propose nonparametric heredity SVMs. Simulated and
real data are used to illustrate the merits of the proposed method.

710.0509 | Techniques on mesh generation for the brain shift simulation | Neurosurgery interventions involve complex tracking systems because a tissue
deformation takesplace. The neuronavigation system relies only on preoperative
images. In order to overcome the soft tissue deformations and guarantee the
accuracy of the navigation a biomechanical model can be used during surgery to
simulate the deformation of the brain. Therefore, a mesh generation for an
optimal real-time Finite Element Model (FEM) becomes crucial. In this work we
present different alternatives from a meshgeneration point of view that were

710.051 | Q-adic Transform revisited | We present an algorithm to perform a simultaneous modular reduction of
several residues. This algorithm is applied fast modular polynomial
multiplication. The idea is to convert the $X$-adic representation of modular
polynomials, with $X$ an indeterminate, to a $q$-adic representation where $q$
is an integer larger than the field characteristic. With some control on the
different involved sizes it is then possible to perform some of the $q$-adic
arithmetic directly with machine integers or floating points. Depending also on
the number of performed numerical operations one can then convert back to the
$q$-adic or $X$-adic representation and eventually mod out high residues. In
this note we present a new version of both conversions: more tabulations and a
way to reduce the number of divisions involved in the process are presented.
The polynomial multiplication is then applied to arithmetic in small finite
field extensions.

710.0512 | Strong coupling expansion for Yang-Mills theory at finite temperature | Euclidean strong coupling expansion of the partition function is applied to
lattice Yang-Mills theory at finite temperature, i.e. for lattices with a
compactified temporal direction. The expansions have a finite radius of
convergence and thus are valid only for $\beta<\beta_c$, where $\beta_c$
denotes the nearest singularity of the free energy on the real axis. The
accessible temperature range is thus the confined regime up to the
deconfinement transition. We have calculated the first few orders of these
expansions of the free energy density as well as the screening masses for the
gauge groups SU(2) and SU(3). The resulting free energy series can be summed up
and corresponds to a glueball gas of the lowest mass glueballs up to the
calculated order. Our result can be used to fix the lower integration constant
for Monte Carlo calculations of the thermodynamic pressure via the integral
method, and shows from first principles that in the confined phase this
constant is indeed exponentially small. Similarly, our results also explain the
weak temperature dependence of glueball screening masses below $T_c$, as
observed in Monte Carlo simulations. Possibilities and difficulties in
extracting $\beta_c$ from the series are discussed.

710.0514 | Miller's instability, microchaos and the short-term evolution of
initially nearby orbits | We study the phase-space behaviour of nearby trajectories in integrable
potentials. We show that the separation of nearby orbits initially diverges
very fast, mimicking a nearly exponential behaviour, while at late times it
grows linearly. This initial exponential phase, known as Miller's instability,
is commonly found in N-body simulations, and has been attributed to short-term
(microscopic) N-body chaos. However we show here analytically that the initial
divergence is simply due to the shape of an orbit in phase-space. This result
confirms previous suspicions that this transient phenomenon is not related to

710.0515 | Poynting's theorem and energy conservation in the propagation of light
in bounded media | Starting from the Maxwell-Lorentz equations, Poynting's theorem is
reconsidered. The energy flux vector is introduced as S_e=(E x B)/mu_0 instead
of E x H, because only by this choice the energy dissipation can be related to
the balance of the kinetic energy of the matter subsystem. Conservation of the
total energy as the sum of kinetic and electromagnetic energy follows. In our
discussion, media and their microscopic nature are represented exactly by their
susceptibility functions, which do not necessarily have to be known. On this
footing, it can be shown that energy conservation in the propagation of light
through bounded media is ensured by Maxwell's boundary conditions alone, even
for some frequently used approximations. This is demonstrated for approaches
using additional boundary conditions and the dielectric approximation in
detail, the latter of which suspected to violate energy conservation for
decades.

710.0517 | The notion of persistence applied to breathers in thermal equilibrium | We study the thermal equilibrium of nonlinear Klein-Gordon chains at the
limit of small coupling (anticontinuum limit). We show that the persistence
distribution associated to the local energy density is a useful tool to study
the statistical distribution of so-called thermal breathers, mainly when the
equilibrium is characterized by long-lived static excitations; in that case,
the distribution of persistence intervals turns out to be a powerlaw. We
demonstrate also that this generic behaviour has a counterpart in the power
spectra, where the high frequencies domains nicely collapse if properly
rescaled. These results are also compared to non linear Klein-Gordon chains
with a soft nonlinearity, for which the thermal breathers are rather mobile
entities. Finally, we discuss the possibility of a breather-induced anomalous
diffusion law, and show that despite a strong slowing-down of the energy
diffusion, there are numerical evidences for a normal asymptotic diffusion
mechanism, but with exceptionnally small diffusion coefficients.

710.052 | Mining the Local Volume | After recent systematic optical, IR, and HI surveys, the total number of
known galaxies within 10 Mpc has increased from 179 to 550. About half this
Local Volume (LV) sample is now been imaged with HST, yielding the galaxy
distances with an accuracy of about 8%. For the majority of the LV galaxies we
currently have H-alpha fluxes that allow us to reconstruct the star formation
history of our neighbourhood.
For the late-type LV galaxies their HI masses and angular momentum follow the
linear relation in the range of 4 orders, which is expected for rotating
gaseous disks being near the gravitational instability threshold.
The data obtained on the LV galaxies imply important cosmological parameters,
in particular, the mean local matter density and HI mass density, as well as
SFR density.
Surprisingly, the local Hubble flow around the LV groups is very quiet, with
1D rms deviations of 25 km/s,which is a signature of the Universe
vacuum-dominated on small scales. The cold infall pattern around nearby groups

710.0523 | Fluctuation theorem applied to Dictyostelium discoideum system | In this paper, we analyze the electrotactic movement of Dictyostelium
discoideum from the viewpoint of non-equilibrium statistical mechanics. Because
we can observe fluctuating behavior of cellular trajectories, we analyze the
probability distribution of the trajectories with the aid of the fluctuation
theorem. Recently, the validity of the fluctuation theorem was verified in a
colloidal system, and it has also been applied to granular systems, turbulent
systems and chemical oscillatory waves to investigate some of their statistical
properties that are not yet completely understood. Noting that the fluctuation

710.0524 | Raman spectra of unfilled and filled carbon nanotubes: Theory | The Raman spectra of two G-bands and a radial breathing mode (RBM) of
unfilled and filled single-wall semiconducting and metallic carbon nanotubes
have been investigated theoretically, in the presence of electron-phonon and
phonon-phonon interactions. Excitation of low frequency optical plasmons in the
metallic nanotube is responsible for the peak known as the Breit-Wigner-Fano
(BWF) line shape in the G-band Raman spectra. In a filled nanotube there is an
additional peak due to excitation of the phonon of the filling atom or
molecule. Positions, shapes and relative strengths of these Raman peaks depend
on the phonon frequencies of the nanotube and that of the filling atoms, and
strengths and forms of the plasmon-phonon and phonon-phonon interactions. For
example, filling atoms with phonon frequency close to the RBM frequency of the
nanotube may broaden and lower the RBM Raman peak to such an extent that it may
become barely visible. Hybridization between the G-bands and the filling atom
phonon is also strong when these two frequencies are close to each other and it
has important effects on the G-band and the BWF line shapes. When the phonon
frequency of the filling atom is far from the RBM and G-band frequencies, it
gives rise to a separate peak with modest effects on the RBM and G-band
spectra. Raman spectra of semiconducting unfilled and filled nanotubes have
similar behavior as those of metallic nanotubes except that normally they have
Lorentzian line shapes and do not show a BWF line shape. However, if a
semiconducting nanotube is filled with donor atoms, it is predicted that the
BWF type line shape may be observed near the RBM, or the G-band or the filling
atom Raman peak.

710.0525 | Hunting long-lived gluinos at the Pierre Auger Observatory | Eventual signals of split sypersymmetry in cosmic ray physics are analyzed in
detail. The study focusses particularly on quasi-stable colorless R-hadrons
originating through confinement of long-lived gluinos (with quarks,
anti-quarks, and gluons) produced in pp collisions at astrophysical sources.
Because of parton density requirements, the gluino has a momentum which is
considerable smaller than the energy of the primary proton, and so production
of heavy (mass ~ 500 GeV) R-hadrons requires powerful cosmic ray engines able
to accelerate particles up to extreme energies, somewhat above 10^{13.6} GeV.
Using a realistic Monte Carlo simulation with the AIRES engine, we study the
main characteristics of the air showers triggered when one of these exotic
hadrons impinges on a stationary nucleon of the Earth atmosphere. We show that
R-hadron air showers present clear differences with respect to those initiated
by standard particles. We use this shower characteristics to construct

710.0527 | The ANTARES detector: background sources and effects on detector
performance | The ANTARES Collaboration is deploying a large neutrino detector at a depth
of 2475 m in the Mediterranean Sea, 40 km off shore from La Seyne-sur-Mer in
South France. The construction of this 12-line detector with 75 phototubes per
line will be completed early 2008. Data taking has begun since April 2005 with
an instrumentation line also equipped with optical modules. The first 5
detector lines are operational since January 2007. The telescope is aimed to
observe high energy cosmic neutrinos through the detection of the Cerenkov
light produced by up-going induced muons. Background sources are due to
atmospheric neutrinos as well as misreconstructed atmospheric muons. Additional
backgrounds inherent to the sea water environment come from 40K decay and
marine organisms' luminescence. While the contribution of the former is
expected to be constant at a level of about 45 kHz, the bioluminescence has
shown large time variations, with periods of very high activity, up to several
hundred kHz. Description of these background sources will be reported, and
effects on detector performance will be described. Methods recently developed
to improve the detection efficiency in high background periods will be
described, together with some of the results obtained.

710.0528 | On the interaction between sharing and linearity | In the analysis of logic programs, abstract domains for detecting sharing and
linearity information are widely used. Devising abstract unification algorithms
for such domains has proved to be rather hard. At the moment, the available
algorithms are correct but not optimal, i.e., they cannot fully exploit the
information conveyed by the abstract domains. In this paper, we define a new
(infinite) domain ShLin-w which can be thought of as a general framework from
which other domains can be easily derived by abstraction. ShLin-w makes the
interaction between sharing and linearity explicit. We provide a constructive
characterization of the optimal abstract unification operator on ShLin-w and we
lift it to two well-known abstractions of ShLin-w. Namely, to the classical
Sharing X Lin abstract domain and to the more precise ShLin-2 abstract domain
by Andy King. In the case of single binding substitutions, we obtain optimal
abstract unification algorithms for such domains.

710.053 | Parametrizing the lepton mixing matrix in terms of deviations from
tri-bimaximal mixing | We propose a parametrization of the lepton mixing matrix in terms of an
expansion in powers of the deviations of the reactor, solar and atmospheric
mixing angles from their tri-bimaximal values. We show that unitarity triangles
and neutrino oscillation formulae have a very compact form when expressed in
this parametrization, resulting in considerable simplifications when dealing
with neutrino phenomenology. The parametrization, which is completely general,
should help to establish possible relations between the deviations of the
reactor, solar and atmospheric mixing angles from their tri-bimaximal values,

710.0531 | The Problem of Localization in Networks of Randomly Deployed Nodes:
Asymptotic and Finite Analysis, and Thresholds | We derive the probability that a randomly chosen NL-node over $S$ gets
localized as a function of a variety of parameters. Then, we derive the
probability that the whole network of NL-nodes over $S$ gets localized. In
connection with the asymptotic thresholds, we show the presence of asymptotic
thresholds on the network localization probability in two different scenarios.
The first refers to dense networks, which arise when the domain $S$ is bounded
and the densities of the two kinds of nodes tend to grow unboundedly. The
second kind of thresholds manifest themselves when the considered domain
increases but the number of nodes grow in such a way that the L-node density
remains constant throughout the investigated domain. In this scenario, what
matters is the minimum value of the maximum transmission range averaged over
the fading process, denoted as $d_{max}$, above which the network of NL-nodes
almost surely gets asymptotically localized.

710.0534 | On the chemical freeze-out criteria in a hot and dense fireball | Intensive investigations of freeze-out criteria in a hot and dense fireball
provide important information regarding particle emission from the fireball. A
systematic comparison of these proposals is presented here in the framework of
a thermodynamically consistent excluded volume model which has been found to
describe the properties of hadron gas (HG) quite well. We find that the impact
of excluded volume correction is considerably large and the average energy per
hadron is 0.9 GeV, $n_b+n_{\bar b}$ stays nearly constant at 0.12/fm$^3$ and
the normalized entropy density $s/T^3\approx 6$ in this model. Moreover, these
values are independent of the beam or center-of-mass energy and also of the
target and beam nuclei. In ideal HG model these quantities show substantial
energy dependence. Further we have compared the predictions of various excluded
volume models in the precise determination of these criteria and we find that
the thermodynamically consistent excluded volume models give the best results.
In addition, we find another important criterion that entropy per hadron has a
constant value at 6 in our model. We hope that these findings will throw
considerable light on the expansion dynamics and the bulk thermodynamic
properties of the fireball before chemical freeze-out.

C$_{60}$ in $\alpha'$--tetra--$kis$--(dimethylamino)--ethylene--C$_{60}$ | We have studied the ground state of a fullerene--based magnet, the
$\alpha'$--phase tetra--$kis$--(dimethylamino)--ethylene--C$_{60}$
($\alpha'$--TDAE--C$_{60}$), by electron spin resonance (ESR) and magnetic
torque measurements. Below T$_N=7$ K, non--paramagnetic field dependent
resonances with a finite excitation gap (1.7 GHz) are observed along the
$a$--axis. Strong enhancement in their intensity as temperature is decreased is
inconsistent with excitation from a singlet state, which had been proposed for
the $\alpha'$--phase ground state. Below T$_N$, non--quadratic field dependence
of magnetic torque signal is also observed in contrast to quadratic field
dependence in the paramagnetic phase. The angle--dependent torque signals below
T$_N$ indicate the existence of an anisotropy of the bulk magnetization. From
both experiments, we propose an antiferromagnetic ground state driven by the
cooperative orientational ordering of C$_{60}$ in the
$\alpha'$--TDAE--C$_{60}$.

fifth dimension of L_s=16 for N_f=2+1 dynamical quark flavors. The lightest
dynamical meson mass in our set-up is around 331 MeV, while partially quenched
mesons reach masses as low as 250 MeV. The applicability of SU(3)xSU(3) and
SU(2)xSU(2) (partially quenched) chiral perturbation theory will be compared
and we quote values for the low-energy constants from both approaches. We will
extract the average light quark and strange quark masses and use a
non-perturbative renormalization technique (RI/MOM) to quote their physical
values. The pion and kaon decay constants are determined at those values from
our chiral fits and their ratio is used to obtain the CKM-matrix element
|V_us|. The results presented here include statistical errors only.

710.0538 | Gap theory of rectification in ballistic three-terminal conductors | We introduce a model for rectification in three-terminal ballistic
conductors, where the central connecting node is modeled as a chaotic cavity.
For bias voltages comparable to the Fermi energy, a strong nonlinearity is
created by the opening of a gap in the transport window. Both noninteracting
cavity electrons at arbitrary temperature as well as the hot electron regime
are considered. Charging effects are treated within the transmission formalism
using a self-consistent analysis. The conductance of the third lead in a
voltage probe configuration is varied to also model inelastic effects. We find
that the basic transport features are insensitive to all of these changes,
indicating that the nonlinearity is robust and well suited to applications such
as current rectification in ballistic systems. Our findings are in broad
agreement with several recent experiments.

open-ended zones with nine lengthwise boundaries. In each zone, a
minimum-length Hamiltonian Path (HP) is found for each combination of boundary
vertices, leading to an approximation for the minimum-length Hamiltonian Cycle

automatically filtering out non-optimal HPs from earlier zones. Although the

710.054 | A disc in the heart of the Ant nebula | We present the discovery of a silicate disc at the centre of the planetary
nebula Mz3 (the Ant). The nebula was observed with MIDI on the Very Large
Telescope Interferometer (VLTI). The visibilities obtained at different
orientations clearly indicate the presence of a dusty, nearly edge-on disc in
the heart of the nebula. An amorphous silicate absorption feature is clearly
seen in our mid-IR spectrum and visibility curves. We used radiative transfer
Monte Carlo simulations to constrain the geometrical and physical parameters of
the disc. We derive an inner radius of 9 AU (~6mas assuming D=1.4kpc). This

710.0541 | Chiral Analysis of the Generalized Form Factors of the Nucleon | We apply the methods of Chiral Perturbation Theory to the analysis of the
first moments of the Generalized Parton Distributions in a Nucleon, usually
known as generalized form factors. These quantities are currently also under
investigation in Lattice QCD analyses of baryon structure, providing simulation
results at large quark masses to be extrapolated to the "real world" via Chiral
Effective Field Theory. We have performed a leading-one-loop calculation in the
covariant framework of Baryon Chiral Perturbation Theory (BChPT), predicting
both the momentum and the quark-mass dependence for all the vector and axial
(generalized) form factors. In particular we discuss the results for the limit
of vanishing four-momentum transfer where the GPD-moments reduce to the well
known moments of Parton Distribution Functions (PDFs). We fit our results to
available lattice QCD data, extrapolating down to the physical point. We
conclude by presenting outstanding results from a combined fit to different
GPDs-moments.

710.0542 | Nuclear skin emergence in Skyrme deformed Hartree-Fock calculations | A study of the charge and matter densities and the corresponding rms radii
for even-even isotopes of Ni, Kr, and Sn has been performed in the framework of
deformed self-consistent mean field Skyrme HF+BCS method. The resulting charge
radii and neutron skin thicknesses of these nuclei are compared with available
experimental data, as well as with other theoretical predictions. The formation
of a neutron skin, which manifests itself in an excess of neutrons at distances
greater than the radius of the proton distribution, is analyzed in terms of
various definitions. Formation of a proton skin is shown to be unlikely. The

710.0544 | Scalar-tensor analysis of an exponential Lagrangian for the
Gravitational Field | Within the scheme of modified gravity, an exponential Lagrangian density will
be considered, and the corresponding scalar-tensor description will be
addressed for both positive and negative values of the cosmological constant.
For negative values of the cosmological term, the potential of the scalar field
exhibits a minimum, around which scalar-field equations can be linearized. The
study of the deSitter regime shows that a comparison with the modified-gravity
description is possible in an off-shell region, i.e., in a region where the
classical equivalence between the two formulations is not fulfilled.
Furthermore, despite the negative cosmological constant, an accelerating
deSitter phase is predicted in the region where the series expansion of the
exponential term does not hold. For positive values of the cosmological
constant, the quantum regime is analyzed within the framework of Loop Quantum
Cosmology.

710.0545 | Synchrotron emission from secondary leptons in microquasar jets | We present a model to estimate the synchrotron radio emission generated in

expansion. The space parameter for the model is explored and the corresponding
spectral energy distributions (SEDs) are presented. We conclude that secondary
leptonic emission represents a significant though hardly dominant contribution
to the total radio emission in MQs, with observational consequences that can be
used to test some still unknown processes occurring in these objects as well as
the nature of the matter outflowing in their jets.

710.0546 | Surface Flows From Magnetograms | Estimates of velocities from time series of photospheric and/or chromospheric
vector magnetograms can be used to determine fluxes of magnetic energy (the
Poynting flux) and helicity across the magnetogram layer, and to provide
time-dependent boundary conditions for data-driven simulations of the solar
atmosphere above this layer. Velocity components perpendicular to the magnetic
field are necessary both to compute these transport rates and to derive model
boundary conditions. Here, we discuss some possible approaches to estimating
perpendicular flows from magnetograms. Since Doppler shifts contain
contributions from flows parallel to the magnetic field, perpendicular
velocities are not generally recoverable from Doppler shifts alone. The
induction equation's vertical component relates evolution in $B_z$ to the
perpendicular flow field, but has a finite null space, meaning some ``null''
flows, e.g., motions along contours of normal field, do not affect $B_z$.
Consequently, additional information is required to accurately specify the
perpendicular flow field. Tracking methods, which analyze $\partial_t B_z$ in a
neighborhood, have a long heritage, but other approaches have recently been
developed. In a recent paper, several such techniques were tested using
synthetic magnetograms from MHD simulations. Here, we use the same test data to
characterize: 1) the ability of the induction equation's normal component, by
itself, to estimate flows; and 2) a tracking method's ability to recover flow
components that are perpendicular to $\mathbf{B}$ and parallel to contours of
$B_z$. This work has been supported by NASA Heliophysics Theory grant

710.0547 | Anatomy of a Young Massive Star Cluster: NGC 1569-B | We present new H-band echelle spectra, obtained with the NIRSPEC spectrograph
at Keck II, for the massive star cluster "B" in the nearby dwarf irregular
galaxy NGC 1569. From spectral synthesis and equivalent width measurements we
obtain abundances and abundance patterns. We derive an Fe abundance of
[Fe/H]=-0.63+/-0.08, a super-solar [alpha/Fe] abundance ratio of +0.31+/-0.09,
and an O abundance of [O/H]=-0.29+/-0.07. We also measure a low 12C/13C = 5+/-1
isotopic ratio. Using archival imaging from the Advanced Camera for Surveys on
board HST, we construct a colour-magnitude diagram (CMD) for the cluster in
which we identify about 60 red supergiant (RSG) stars, consistent with the
strong RSG features seen in the H-band spectrum. The mean effective temperature
of these RSGs, derived from their observed colours and weighted by their
estimated H-band luminosities, is 3790 K, in excellent agreement with our
spectroscopic estimate of Teff = 3800+/-200 K. From the CMD we derive an age of
15-25 Myr, slightly older than previous estimates based on integrated
broad-band colours. We derive a radial velocity of -78+/-3 km/s and a velocity
dispersion of 9.6+/-0.3 km/s. In combination with an estimate of the half-light
radius of 0.20"+/-0.05" from the HST data, this leads to a dynamical mass of
(4.4+/-1.1)E5 Msun. The dynamical mass agrees very well with the mass predicted
by simple stellar population models for a cluster of this age and luminosity,
assuming a normal stellar IMF. The cluster core radius appears smaller at
longer wavelengths, as has previously been found in other extragalactic young
star clusters.

take into account experimental phase-shift measurements in the elastic channel

710.0552 | High loop renormalization constants by NSPT: a status report | We present an update on Numerical Stochastic Perturbation Theory projects for
Lattice QCD, which are by now run on apeNEXT. As a first issue, we discuss a
strategy to tackle finite size effects which can be quite sizeable in the
computation of logarithmically divergent renormalization constants. Our first
high loop determination of quark bilinears for Wilson fermions was limited to
finite constants and finite ratios. A precise determination of Z_P and Z_S (and
hence of Z_m) now becomes possible. We also give an account of computations for
actions different from the standard regularization we have taken into account
so far (Wilson gauge action and Wilson fermions). In particular, we present the
status of computations for the Lattice QCD regularization defined by tree level
Symanzik improved gauge action and Wilson fermions, which became quite popular
in recent times. We also take the chance to discuss the related topic of the
computation of the gluon and ghost propagators (which we undertook in
collaboration with another group). This is relevant in order to better
understand non-perturbative computations of propagators aiming at
qualitative/quantitative understanding of confinement.
