710.3353 | Roadmap for ILC Detector R&D Test Beams | This document provides a roadmap for ILC detector test beam needs in the next
3 - 5 years. In this period, detector Letters of Intent are expected by fall
2008, the ILC Engineering Design Report to be submitted in ILC and its
detectors in 2012. ILC detectors are required to have unprecedented precision
to be able to elucidate new physics discoveries at TeV energies from the LHC
and ILC machines, and to fully exploit experimental investifation at the
electrweak unification energy scale. Ahieving this requires significant
investment for detector test beam activities to complete the R&D needed, to
test prototypes and (later) to qualify final detector system desgns, including
integated system tess. This roadmap document describes the need for significant
increases in resources for ILC test beam activities. It should be used by test
beam facility managers and the worldwide ILC leadership to assure that the
necessary resources and facilities are made available to meet the needs in
time.

710.3354 | Exact-exchange energy density in the gauge of a semilocal density
functional approximation | Exact-exchange energy density and energy density of a semilocal density
functional approximation are two key ingredients for modeling the static
correlation, a strongly nonlocal functional of the density, through a local
hybrid functional. Because energy densities are not uniquely defined, the
conventional (Slater) exact-exchange energy density
$e_\mathrm{x}^\mathrm{ex(conv)}$ is not necessarily well-suited for local
mixing with a given semilocal approximation. We show how to transform
$e_\mathrm{x}^\mathrm{ex(conv)}$ in order to make it compatible with an
arbitrary semilocal density functional, taking the nonempirical
meta-generalized gradient approximation of Tao, Perdew, Staroverov, and
Scuseria (TPSS) as an example. Our additive gauge transformation function
integrates to zero, satisfies exact constraints, and is most important where
the density is dominated by a single orbital shape. We show that, as expected,
the difference between semilocal and exact-exchange energy densities becomes
more negative under bond stretching in He$_2^{+}$ and related systems. Our
construction of $e_\mathrm{x}^\mathrm{ex(conv)}$ by a
resolution-of-the-identity method requires uncontracted basis functions.

710.3355 | Lensing Systematics from Space: Modeling PSF effects in the SNAP survey | Anisotropy in the point spread function (PSF) contributes a systematic error
to weak lensing measurements. In this study we use a ray tracer that
incorporates all the optical elements of the SNAP telescope to estimate this
effect. Misalignments in the optics generates PSF anisotropy, which we
characterize by its ellipticity. The effect of three time varying effects:
thermal drift, guider jitter, and structural vibration on the PSF are estimated
for expected parameters of the SNAP telescope. Multiple realizations of a
thousand square degree mock survey are then generated to include the systematic
error pattern induced by these effects. We quantify their contribution to the
power spectrum of the lensing shear. We find that the dominant effect comes
from the thermal drift, which peaks at angular wavenumbers l ~ 10^3, but its
amplitude is over one order of magnitude smaller than the size of the expected
statistical error. While there are significant uncertainties in our modeling,

710.3356 | Freyd's generating hypothesis for groups with periodic cohomology | Let $G$ be a finite group and let $k$ be a field whose characteristic $p$
divides the order of $G$. Freyd's generating hypothesis for the stable module
category of $G$ is the statement that a map between finite-dimensional
$kG$-modules in the thick subcategory generated by $k$ factors through a
projective if the induced map on Tate cohomology is trivial. We show that if
$G$ has periodic cohomology then the generating hypothesis holds if and only if
the Sylow $p$-subgroup of $G$ is $C_2$ or $C_3$. We also give some other
conditions that are equivalent to the GH for groups with periodic cohomology.

It is known from the theory of Andreotti and Grauert that if a complex space $X$ is $q$-complete, then $X$ is cohomoloogically $q$-complete. Until now it is not known in general if these two conditions are equivalent. The aim of section $4$ of this article is to provide a counterexample to the conjecture posed by Andreotti and Grauert ~\cite{ref2} to show that a cohomologically $q$-complete space is not necessarily $q$-complete. In section $5$ of this article, we will prove that there exist for each pair of integers $(n,q)$ with $2\leq q\leq n-1$ a $q$-complete with corners open subset $D$ of $\mathbb{P}^{n}$ and $\mathcal{F}\in coh(\mathbb{P}^{n})$ such that $D$ is not cohomologically $\hat{q}$-complete with respect to ${\mathcal{F}}$.

710.3359 | Generation of Magnetic Field by Combined Action of Turbulence and Shear | The feasibility of a mean-field dynamo in nonhelical turbulence with
superimposed linear shear is studied numerically in elongated shearing boxes.
Exponential growth of magnetic field at scales much larger than the outer scale
of the turbulence is found. The charateristic scale of the field is l_B ~
S^{-1/2} and growth rate is gamma ~ S, where S is the shearing rate. This newly
discovered shear dynamo effect potentially represents a very generic mechanism

710.336 | Detailed magnetization study of superconducting properties of YBCO
ceramic spheres | We present a magnetization study of low density YBCO ceramics carried out in
magnetic fields 0.5 Oe < H < 50 kOe. It was demonstrated that superconducting
links between grains may be completely suppressed either by a magnetic field of
the order of 100 Oe (at low temperatures) or by an increase of temperature
above 70 K. This property of present samples allowed to evaluate the ratio
between an average grain size and the magnetic field penetration depth lambda.
Furthermore, at temperatures T > 85 K, using low-field magnetization
measurements, we could evaluate the temperature dependence of lambda, which
turned out to be very close to predictions of the conventional Ginzburg-Landau
theory. Although present samples consisted of randomly oriented grains,
specifics of magnetization measurements allowed for evaluation of lambda_ab(T).
Good agreement between our estimation of the grain size with the real sample
structure provides evidence for the validity of this analysis of magnetization
data. Measurements of equilibrium magnetization in high magnetic fields were
used for evaluation of Hc2(T). At temperatures close to T_c, the Hc2(T)
dependence turned out to be linear in agreement with the Ginzburg-Landau
theory. The value of temperature, at which Hc2 vanishes, coincides with the
superconducting critical temperature evaluated from low-field measurements.

710.3361 | Final results on nu_mu to nu_tau oscillation from the CHORUS experiment | The final oscillation analysis of the complete set of data collected by
CHORUS in the years 1994--1997 is presented. Reconstruction algorithms of data
extracted by electronic detectors were improved and the data recorded in the
emulsion target were analysed by new automated scanning systems, allowing the
use of a new method for event reconstruction in emulsion. CHORUS has applied
these new techniques to the sample of 1996--1997 events for which no muons were
observed in the electronic detectors. Combining the new sample with the data
analysed in previous papers, the overall sensitivity of the experiment to the
$\nu_\tau$ appearance is thus improved. In a two-neutrino mixing scheme, a 90%
C.L. upper limit of $\sin^2 2\theta_{\mu\tau} < 4.4 \times 10^{-4}$ is set for

710.3362 | Scale-renormalized matrix-product states for correlated quantum systems | A generalization of matrix product states (MPS) is introduced which is
suitable for describing interacting quantum systems in two and three
dimensions. These scale-renormalized matrix-product states (SR-MPS) are based
on a course-graining of the lattice in which the blocks at each level are
associated with matrix products that are further transformed (scale
renormalized) with other matrices before they are assembled to form blocks at
the next level. Using variational Monte Carlo simulations of the
two-dimensional transverse-field Ising model as a test, it is shown that the
SR-MPS converge much more rapidly with the matrix size than a standard MPS. It
is also shown that the use of lattice-symmetries speeds up the convergence very
significantly.

710.3363 | Using X-ray observations to identify the particle acceleration
mechanisms in VHE SNRs and "dark" VHE sources | Very high energy (VHE) gamma-ray observations have proven to be very
successful in localizing Galactic acceleration sites of VHE particles.
Observations of shell-type supernova remnants have confirmed that particles are
accelerated to VHE energies in supernova blast waves; the interpretation of the
gamma-ray data in terms of hadronic or leptonic particle components in these
objects relies nevertheless strongly on input from X-ray observations. The
largest identified Galactic VHE source class consists of pulsar wind nebulae,
as detected in X-rays. Many of the remaining VHE sources remain however
unidentified until now. With X-ray observations of these enigmatic "dark"
objects one hopes to solve the following questions: What is the astrophysical
nature of these sources? Are they predominantly electron or hadron
accelerators? And what is their contribution to the overall cosmic ray energy

710.3364 | Spectral properties of the nonspherically decaying radiation generated
by a rotating superluminal source | The focusing of the radiation generated by a polarization current with a
superluminally rotating distribution pattern is of a higher order in the plane
of rotation than in other directions. Consequently, our previously published
asymptotic approximation to the value of this field outside the equatorial
plane breaks down as the line of sight approaches a direction normal to the
rotation axis, i.e., is nonuniform with respect to the polar angle. Here we
employ an alternative asymptotic expansion to show that, though having a rate
of decay with frequency (mu) that is by a factor of order mu^(2/3) slower, the
equatorial radiation field has the same dependence on distance as the
nonspherically decaying component of the generated field in other directions:
it, too, diminishes as the inverse square root of the distance from its source.
We also briefly discuss the relevance of these results to the giant pulses
received from pulsars: the focused, nonspherically decaying pulses that arise
from a superluminal polarization current in a highly magnetized plasma have a
power-law spectrum (i.e., a flux density proportional to mu^alpha) whose index
(alpha) is given by one of the values -2/3, -2, -8/3, or -4.

710.3365 | Singular Yamabe metrics and initial data with exactly
Kottler-Schwarzschild-de Sitter ends | We construct large families of initial data sets for the vacuum Einstein
equations with positive cosmological constant which contain exactly Delaunay
ends; these are non-trivial initial data sets which coincide with those for the
Kottler-Schwarzschild-de Sitter metrics in regions of infinite extent. From the
purely Riemannian geometric point of view, this produces complete, constant
positive scalar curvature metrics with exact Delaunay ends which are not
globally Delaunay. The ends can be used to construct new compact initial data
sets via gluing constructions. The construction provided applies to more

710.3368 | Local power fluctuations in two-dimensional turbulence | The statistics of power fluctuations are studied in simulations of
two-dimensional turbulence in both inverse (energy) and direct (enstrophy)
cascade regimes from both Lagrangian and Eulerian perspectives. The probability
density function (PDF) of the appropriately defined dimensionless power is
strongly non-gaussian with asymmetric exponential tails. This distribution can
be modeled by the distribution of the product of correlated normal variables
allowing a derivation of the asymptotics of the tails. The PDF of the
dimensionless power is shown to exhibit an empirical Fluctuation Relation. An
expression for the entropy production rate is deduced from the asymptotic form

710.3369 | Multi-Fluid Simulation of the Magnetic Field Evolution in Neutron Stars | Using a numerical simulation, we study the effects of ambipolar diffusion and
ohmic diffusion on the magnetic field evolution in the interior of an isolated
neutron star. We are interested in the behavior of the magnetic field on a long
time scale, over which all Alfven and sound waves have been damped. We model
the stellar interior as an electrically neutral plasma composed of neutrons,
protons and electrons, which can interact with each other through collisions
and electromagnetic forces. Weak interactions convert neutrons and charged
particles into each other, erasing chemical imbalances. As a first step, we
assume that the magnetic field points in one fixed Cartesian direction but can
vary along an orthogonal direction. We start with a uniform-density background
threaded by a homogeneous magnetic field and study the evolution of a magnetic
perturbation as well as the density fluctuations it induces in the particles.
We show that the system evolves through different quasi-equilibrium states and
estimate the characteristic time scales on which these quasi-equilibria occur.

710.3371 | Segregation process and phase transition in cyclic predator-prey models
with even number of species | We study a spatial cyclic predator-prey model with an even number of species
(for n=4, 6, and 8) that allows the formation of two defective alliances
consisting of the even and odd label species. The species are distributed on
the sites of a square lattice. The evolution of spatial distribution is
governed by iteration of two elementary processes on neighboring sites chosen
randomly: if the sites are occupied by a predator-prey pair then the predator
invades the prey's site; otherwise the species exchange their site with a
probability $X$. For low $X$ values a self-organizing pattern is maintained by
cyclic invasions. If $X$ exceeds a threshold value then two types of domains
grow up that formed by the odd and even label species, respectively. Monte
Carlo simulations indicate the blocking of this segregation process within a
range of X for n=8.

710.3373 | Driven Intrinsic Localized Modes in a Coupled Pendulum Array | Intrinsic localized modes (ILMs), also called discrete breathers, are
directly generated via modulational instability in an array of coupled
pendulums. These ILMs can be stabilized over a range of driver frequencies and
amplitudes. They are characterized by a pi-phase difference between their
center and wings. At higher driver frequencies, these ILMs are observed to

Transmitter | Inner and outer bounds are established on the capacity region of two-sender,
two-receiver interference channels where one transmitter knows both messages.
The transmitter with extra knowledge is referred to as being cognitive. The
inner bound is based on strategies that generalize prior work, and include
rate-splitting, Gel'fand-Pinsker coding and cooperative transmission. A general
outer bound is based on the Nair-El Gamal outer bound for broadcast channels. A
simpler bound is presented for the case in which one of the decoders can decode
both messages. The bounds are evaluated and compared for Gaussian channels.

710.3376 | Superfluid density of superconductor-ferromagnet bilayers | We report the first measurements of the effective superfluid density n_S(T)
\propto \lambda^{-2}(T) of Superconductor-Ferromagnet (SC/FM) bilayers, where
\lambda is the effective magnetic field penetration depth. Thin Nb/Ni bilayers
were sputtered in ultrahigh vacuum in quick succession onto oxidized Si
substrates. Nb layers are 102 A thick for all samples, while Ni thicknesses
vary from 0 to 100 A. T_C determined from \lambda^{-2}(T) decreases rapidly as
Ni thickness d_Ni increases from zero to 15 A, then it has a shallow minimum at
d_Ni \approx 25 A. \lambda^{-2}(0) behaves similarly, but has a minimum several
times deeper. In fact, \lambda^{-2}(0) continues to increase with increasing Ni

710.3377 | Transient Random Walks in Random Environment on a Galton-Watson Tree | We consider a transient random walk $(X_n)$ in random environment on a
Galton--Watson tree. Under fairly general assumptions, we give a sharp and
explicit criterion for the asymptotic speed to be positive. As a consequence,
situations with zero speed are revealed to occur. In such cases, we prove that
$X_n$ is of order of magnitude $n^{\Lambda}$, with $\Lambda \in (0,1)$. We also
show that the linearly edge reinforced random walk on a regular tree always has
a positive asymptotic speed, which improves a recent result of Collevecchio
\cite{Col06}.

710.3378 | Simu-LC : a Light-Curve simulator for CoRoT | Simulating the data that a space instrument like COROT will provide might
look presomptuous. Indeed, it is certainly, when comparing to previous
comparable instruments like IPHIR or GOLF. These two examples show that the
nominal behaviour of the instrument is not always reached, but this does not
prevent this instrument to provide very interesting data. However, despite some
technical problems, IPHIR and GOLF yielded a wealth of scientific results.
Thus, what is the interest of simulating COROT data? How close to reality these
simualtions will get? This might not be the most important fact as the
preparation of these simulations will help us to prepare the analysis of real
data and to be ready in case of unexpected technical behaviour of the
instrument perturbating the data, or unexpected physical behaviour of the
targets of the instrument. A consequence of that is that the simulation tool
must include technical and physical aspects, making the task even more
difficult. These aspects cover: photon noise, p modes excitation, granulation
signal, stellar activity signal, orbital perturbations, stellar rotation...

710.3379 | Asymptotic description of solitary wave trains in fully nonlinear
shallow-water theory | We derive an asymptotic formula for the amplitude distribution in a fully
nonlinear shallow-water solitary wave train which is formed as the long-time
outcome of the initial-value problem for the Su-Gardner (or one-dimensional
Green-Naghdi) system. Our analysis is based on the properties of the
characteristics of the associated Whitham modulation system which describes an
intermediate "undular bore" stage of the evolution. The resulting formula
represents a "non-integrable" analogue of the well-known semi-classical
distribution for the Korteweg-de Vries equation, which is usually obtained
through the inverse scattering transform. Our analytical results are shown to
agree with the results of direct numerical simulations of the Su-Gardner
system. Our analysis can be generalised to other weakly dispersive, fully
nonlinear systems which are not necessarily completely integrable.

carbon nanotubes | This work considers the g-tensor anisotropy induced by the flexural thermal
vibrations in one-dimensional structures and its role in electron spin
relaxation. In particular, the mechanism of spin-lattice relaxation via
flexural modes is studied theoretically for localized and delocalized
electronic states in semiconducting carbon nanotubes in the presence of
magnetic field. The calculation of one-phonon spin-flip process predicts
distinctive dependencies of the relaxation rate on temperature, magnetic field
and nanotube diameter. Comparison with the spin relaxation caused by the
hyperfine interaction clearly suggests the relative efficiency of the proposed
mechanism at sufficiently high temperatures. Specifically, the longitudinal
spin relaxation time in the semiconducting carbon nanotubes is estimated to be
as short as 30 microseconds at room temperature.

710.3383 | Simultaneous Multi-Wavelength Observations of Magnetic Activity in
Ultracool Dwarfs. II. Mixed Trends in VB10 and LSR1835+32 and the Possible
Role of Rotation | [Abridged] As part of our on-going investigation of magnetic activity in
ultracool dwarfs we present simultaneous radio, X-ray, UV, and optical
observations of LSR1835+32 (M8.5), and simultaneous X-ray and UV observations
of VB10 (M8), both with a duration of about 9 hours. LSR1835+32 exhibits
persistent radio emission and H-alpha variability on timescales of ~0.5-2 hr.
The detected UV flux is consistent with photospheric emission, and no X-ray
emission is detected to a deep limit of L_X/L_bol<10^-5.7. The H-alpha and
radio emission are temporally uncorrelated, and the ratio of radio to X-ray
luminosity exceeds the correlation seen in F-M6 stars by >2x10^4. Similarly,
L_Halpha/L_X>10 is at least 30 times larger than in early M dwarfs, and
eliminates coronal emission as the source of chromospheric heating. The lack of
radio variability during four rotations of LSR1835+32 requires a uniform
stellar-scale field of ~10 G, and indicates that the H-alpha variability is
dominated by much smaller scales, <10% of the chromospheric volume. VB10, on
the other hand, shows correlated flaring and quiescent X-ray and UV emission,
similar to the behavior of early M dwarfs. Delayed and densely-sampled optical
spectra exhibit a similar range of variability amplitudes and timescales to
those seen in the X-rays and UV, with L_Halpha/L_X~1. Along with our previous
observations of the M8.5 dwarf TVLM513-46546 we conclude that late M dwarfs
exhibit a mix of activity patterns, which points to a transition in the
structure and heating of the outer atmosphere by large-scale magnetic fields.
We find that rotation may play a role in generating the fields as evidenced by
a tentative correlation between radio activity and rotation velocity. The X-ray
emission, however, shows evidence for super-saturation at vsini>25 km/s.

710.3384 | Spitzer Constraints on the Stellar Populations of Lyman-Alpha Emitting
Galaxies at z = 3.1 | We investigate the stellar populations of a sample of 162 Lyman-alpha
emitting galaxies (LAEs) at z = 3.1 in the Extended Chandra Deep Field South,
using deep Spitzer IRAC data available from the GOODS and SIMPLE surveys to
derive reliable stellar population estimates. We divide the LAEs according to
their rest-frame near-IR luminosities into IRAC-detected and IRAC-undetected
samples. About 70% of the LAEs are undetected in 3.6 micron down to [3.6] =
25.2 AB. Stacking analysis reveals that the average stellar population of the
IRAC-undetected sample has an age of ~ 200 Myr and a mass of ~ 3x10^8 solar
masses, consistent with the expectation that LAEs are mostly young and low-mass
galaxies. On the other hand, the IRAC-detected LAEs are on average
significantly older and more massive, with an average age > 1 Gyr and mass ~
10^10 solar masses. Comparing the IRAC colors and magnitudes of the LAEs to z ~
3 Lyman break galaxies (LBGs) shows that the IRAC-detected LAEs lie at the
faint blue end of the LBG color-magnitude distribution, suggesting that
IRAC-detected LAEs may be the low mass extension of the LBG population. We also
present tentative evidence for a small fraction (~ 5%) of obscured AGN within
the LAE sample. Our results suggest that LAEs posses a wide range of ages and
masses. Additionally, the presence of evolved stellar populations inside LAEs
suggests that the Lyman-alpha luminous phase of galaxies may either be a
long-lasting or recurring phenomenon.

710.3385 | Molecular Recollision Interferometry in High Harmonic Generation | We use extreme-ultraviolet interferometry to measure the phase of high-order
harmonic generation from transiently aligned CO2 molecules. We unambiguously
observe a reversal in phase of the high order harmonic emission for higher
harmonic orders with a sufficient degree of alignment. This results from
molecular-scale quantum interferences between the molecular electronic wave
function and the recolliding electron as it recombines with the molecule, and
is consistent with a two-center model. Furthermore, using the combined harmonic
intensity and phase information, we extract accurate information on the
dispersion relation of the returning electron wavepacket as a function of

710.3386 | Priority diffusion model in lattices and complex networks | We introduce a model for diffusion of two classes of particles ($A$ and $B$)
with priority: where both species are present in the same site the motion of
$A$'s takes precedence over that of $B$'s. This describes realistic situations
in wireless and communication networks. In regular lattices the diffusion of
the two species is normal but the $B$ particles are significantly slower, due
to the presence of the $A$ particles. From the fraction of sites where the $B$
particles can move freely, which we compute analytically, we derive the
diffusion coefficients of the two species. In heterogeneous networks the
fraction of sites where $B$ is free decreases exponentially with the degree of
the sites. This, coupled with accumulation of particles in high-degree nodes
leads to trapping of the low priority particles in scale-free networks.

710.339 | Efficient algorithms for rigid body integration using optimized
splitting methods and exact free rotational motion | Hamiltonian splitting methods are an established technique to derive stable
and accurate integration schemes in molecular dynamics, in which additional
accuracy can be gained using force gradients. For rigid bodies, a tradition
exists in the literature to further split up the kinetic part of the
Hamiltonian, which lowers the accuracy. The goal of this note is to comment on
the best combination of optimized splitting and gradient methods that avoids
splitting the kinetic energy. These schemes are generally applicable, but the
optimal scheme depends on the desired level of accuracy. For simulations of
liquid water it is found that the velocity Verlet scheme is only optimal for
crude simulations with accuracies larger than 1.5%, while surprisingly a

710.3392 | Differential operators and BV structures in noncommutative geometry | We introduce a new formalism of differential operators for a general
associative algebra A. It replaces Grothendieck's notion of differential
operator on a commutative algebra in such a way that derivations of the
commutative algebra are replaced by DDer(A), the bimodule of double
derivations. Our differential operators act not on the algebra A itself but
rather on F(A), a certain `Fock space' associated to any noncommutative algebra
A in a functorial way. The corresponding algebra D(F(A)), of differential
operators, is filtered and gr D(F(A)), the associated graded algebra, is
commutative in some `twisted' sense. The resulting double Poisson structure on
gr D(F(A)) is closely related to the one introduced by Van den Bergh.
Specifically, we prove that gr D(F(A))=F(T_A(DDer(A)), provided A is smooth.
It is crucial for our construction that the Fock space F(A) carries an
extra-structure of a wheelgebra, a new notion closely related to the notion of
a wheeled PROP. There are also notions of Lie wheelgebras, and so on. In that
language, D(F(A)) becomes the universal enveloping wheelgebra of a Lie
wheelgebroid of double derivations.
In the second part of the paper we show, extending a classical construction
of Koszul to the noncommutative setting, that any Ricci-flat, torsion-free
bimodule connection on DDer(A) gives rise to a second order (wheeled)
differential operator, a noncommutative analogue of the BV-operator.

710.3394 | On the systematics of asteroseismological mass determinations of PG1159
stars | We analyze systematics in the asteroseismological mass determination methods
in pulsating PG 1159 stars. We compare the seismic masses resulting from the
comparison of the observed mean period spacings with the usually adopted
asymptotic period spacings, and the average of the computed period spacings.
Computations are based on full PG1159 evolutionary models with stellar masses
ranging from 0.530 to 0.741 Mo that take into account the complete evolution of
progenitor stars. We conclude that asteroseismology is a precise and powerful
technique that determines the masses to a high internal accuracy, but it
depends on the adopted mass determination method. In particular, we find that
in the case of pulsating PG 1159 stars characterized by short pulsation
periods, like PG 2131+066 and PG 0122+200, the employment of the asymptotic
period spacings overestimates the stellar mass by about 0.06 Mo as compared
with inferences from the average of the period spacings. In this case, the
discrepancy between asteroseismological and spectroscopical masses is markedly
reduced when use is made of the mean period spacing instead of the asymptotic
period spacing.

710.3395 | If LHC is a Mini-Time-Machines Factory, Can We Notice? | Assuming the hypothesis of TeV-scale multi-dimensional gravity, one can
imagine that at LHC not only mini-black-holes (MBH) will be intensively
created, but also other exotic gravitational configurations, including
hypothetical mini-time-machines (MTM). Like MBH, they should quickly evaporate,
but one can wonder if their temporal existence at the moment of high-energy
collision can leave any traces in the observable data. We briefly discuss five
thinkable effects: (i) change of the energy spectrum due to the
frequency-filtration property of MTM, (ii) possible production of anomalously
energetic particles, accelerated by passing many times through gravitational
field inside the MTM, (iii) acceleration of particle decays, since the proper
time of a particle moving inside MTM can strongly exceed the laboratory time,
(iv) CPT and naive unitarity violation (thermalization) due to effective
non-local interactions caused by MTM and to possible ambiguity in the
population of closed world-lines inside MTM, (v) collective effects due to
conversion of a single particle into a bunch of its co-existing copies within
the MTM. Despite possible particle-antiparticle conversion inside MTM, they do
not seem to produce any specific CP-violation effects.

710.3396 | The Zero Age Main Sequence of WIMP burners | We modify a stellar structure code to estimate the effect upon the main
sequence of the accretion of weakly interacting dark matter onto stars and its
subsequent annihilation. The effect upon the stars depends upon whether the
energy generation rate from dark matter annihilation is large enough to shut
off the nuclear burning in the star. Main sequence WIMP burners look much like
protostars moving on the Hayashi track, although they are in principle
completely stable. We make some brief comments about where such stars could be
found, how they might be observed and more detailed simulations which are
currently in progress. Finally we comment on whether or not it is possible to
link the paradoxically young OB stars found at the galactic centre with WIMP
burners.

710.3397 | Seventy Years of the EPR Paradox | In spite of the fact that statistical predictions of quantum theory (QT) can
only be tested if large amount of data is available a claim has been made that
QT provides the most complete description of an individual physical system.
Einstein's opposition to this claim and the paradox he presented in the article
written together with Podolsky and Rosen in 1935 inspired generations of
physicists in their quest for better understanding of QT. Seventy years after
EPR article it is clear that without deep understanding of the character and
limitations of QT one may not hope to find a meaningful unified theory of all
physical interactions, manipulate qubits or construct a quantum computer. In
this paper we present shortly the EPR paper and the discussion which followed
it. By emphasizing the difference between quantum phenomena and hypothetical
invisible sub phenomena we show that paradoxes are only found if incorrect
models of sub phenomena are used. The violation of Bell and CHSH inequalities
demonstrate clearly that "an entangled pair of photons" resembles neither "a
pair of Bertlmann's socks" nor "a pair of fair and random dices". Finally we
rephrase the EPR question by asking whether QT provides the complete
description of experimental data.

710.3398 | Simple derivation of the special theory of relativity without the speed
of light axiom | We show a very simple yet rigorous derivation of the invariance of the
space-time interval (and hence the whole special relativity) just from the
isotropy, homogeneity and a principle of relativity, without the need of the
speed of light axiom. This article is intended as a textbook explanation of the
special relativity.

710.3399 | From Solar and Stellar Flares to Coronal Heating: Theory and
Observations of How Magnetic Reconnection Regulates Coronal Conditions | There is currently no explanation of why the corona has the temperature and
density it has. We present a model which explains how the dynamics of magnetic
reconnection regulates the conditions in the corona. A bifurcation in magnetic
reconnection at a critical state enforces an upper bound on the coronal
temperature for a given density. We present observational evidence from 107
flares in 37 sun-like stars that stellar coronae are near this critical state.
The model may be important to self-organized criticality models of the solar
corona.

710.34 | Intra Cluster Globular Clusters around NGC 1399 in Fornax? | We investigate whether the globular clusters (GCs) in the recently published
sample of GCs in the Fornax cluster by Bergond and coworkers are indeed
intra-cluster objects. We combine the catalogue of radial velocity measurements
by Bergond et al. with our CTIO MOSAIC photometry in the Washington system and
analyse the relation of metal-poor and metal-rich GCs with their host galaxies.
The metal-rich GCs appear to be kinematically associated with their respective
host galaxies. The vast majority of the metal-poor GCs found in between the
galaxies of the Fornax cluster have velocities which are consistent with them
being members of the very extended NGC 1399 GC system. We find that when the
sample is restricted to the most accurate velocity measurements, the GC
velocity dispersion profile can be described with a mass model derived for the
NGC 1399 GC system within 80 kpc. We identify one ``vagrant'' GC whose radial

710.3402 | The 't Hooft Model As A Hologram | We consider the 3d dual of 1+1 dimensional large-N_c QCD with quarks in the
fundamental representation, also known as the 't Hooft model. 't Hooft solved
this model by deriving a Schroedinger equation for the wavefunction of a parton
inside the meson. In the scale-invariant limit, we show how this equation is
related by a transform to the equation of motion for a scalar field in AdS_3.
We thus find an explicit map between the `parton-x' variable and the radial
coordinate of AdS_3. This direct map allows us to check the AdS/CFT
prescription from the 2d side. We describe various features of the dual in the

boundary conditions. We obtain complete asymptotic expansions for the $k$th
eigenvalue and the eigenfunctions, uniformly for $k\leq C\epsilon^{-1}$, in
terms of scattering data on a non-compact limit space. We then use this to
determine the quantum graph which is to be regarded as the limit object, in a
spectral sense, of the family $(G_\epsilon)$.
Our method is a direct construction of approximate eigenfunctions from the
scattering and graph data, and use of a priori estimates to show that all
eigenfunctions are obtained in this way.

710.3406 | Two-component jet simulations: I. Topological stability of analytical
MHD outflow solutions | Observations of collimated outflows in young stellar objects indicate that
several features of the jets can be understood by adopting the picture of a
two-component outflow, wherein a central stellar component around the jet axis
is surrounded by an extended disk-wind. The precise contribution of each
component may depend on the intrinsic physical properties of the YSO-disk
system as well as its evolutionary stage. In this context, the present article
starts a systematic investigation of two-component jet models via
time-dependent simulations of two prototypical and complementary analytical
solutions, each closely related to the properties of stellar-outflows and
disk-winds. These models describe a meridionally and a radially self-similar
exact solution of the steady-state, ideal hydromagnetic equations,
respectively. By using the PLUTO code to carry out the simulations, the study
focuses on the topological stability of each of the two analytical solutions,
which are successfully extended to all space by removing their singularities.
In addition, their behavior and robustness over several physical and numerical
modifications is extensively examined. It is found that radially self-similar
solutions (disk-winds) always reach a final steady-state while maintaining all
their well-defined properties. The different ways to replace the singular part
of the solution around the symmetry axis, being a first approximation towards a
two-component outflow, lead to the appearance of a shock at the super-fast
domain corresponding to the fast magnetosonic separatrix surface. Conversely,
the asymptotic configuration and the stability of meridionally self-similar
models (stellar-winds) is related to the heating processes at the base of the
wind.

710.3407 | Little Higgs, Non-standard Higgs, No Higgs and All That | We give a brief review of recent developments in non-supersymmetric models
for electroweak symmetry breaking, including little Higgs, composite Higgs and
Higgsless theories. The new ideas such as extra dimensions, AdS/CFT
correspondence, dimension-deconstruction, and collective symmetry breaking

in a specific case - ab-initio pseudopotential generating process - which is
needed within the electronic structure calculations using a Density Functional

introduction to DFT, derive the radial Dirac and Schrodinger equations, show
how to solve them both for a given energy and as an eigenvalue problem using a
known asymptotic behavior of the solution. Next we compare the nonrelativistic

In particular, we construct an iterable method of determining the

710.341 | Creation of neutral fundamental particles in the Weyl-Dirac version of
Wesson's IMT | Spherically symmetric entities filled with matter induced by the 5D Bulk may
be built in the empty 4D space-time. The substance of the entity, the latter
regarded as a fundamental particle, is characterized by the prematter equ. of
state P=-rho. the particle is coverede by a Schwarzschild-like envelope and
from the outside it is characterized by mass and radius. One regard these
entities as neutral fundamental particles being constituents of quarks and

710.3411 | Input Impedance, Nanocircuit Loading, and Radiation Tuning of Optical
Nanoantennas | Here we explore the radiation features of optical nanoantennas, analyzing the
concepts of input impedance, optical radiation resistance, impedance matching
and loading of plasmonic nanodipoles. We discuss how the concept of antenna
impedance may be applied to optical frequencies, and how its quantity may be
properly defined and evaluated. We exploit these concepts in optimization of
nanoantenna loading by optical nanocircuit elements, extending classic concepts
of radio-frequency antenna theory to the visible regime for the proper design
and matching of plasmonic nanoantennas.

710.3414 | Kaon Weak Matrix Elements in 2+1 flavor DWF QCD | $K \to \pi$ and $K \to 0$ weak matrix elements of $\Delta S = 1$ operators
have been measured in 2+1 flavor domain wall fermion (DWF) QCD on (3 fm)$^3$
lattices with $a^{-1} = 1.73(3)$ GeV. As is well known, using these matrix
elements and chiral perturbation theory allows a determination of the $K \to
\pi \pi$ matrix elements that enter in the quantitative value for the $\Delta I
= 1/2$ rule and $\epsilon^\prime/\epsilon$. Two light dynamical sea quark
masses have been used, along with six valence quark masses, with the lightest
valence quark mass $\approx 1/10$ the physical strange quark mass. We report
our results for lattice matrix elements in the $SU(3)_L \times SU(3)_R$ (27,1),
(8,1), and (8,8) representations, paying particular attention to the
statistical errors achieved after measurements on 75 configurations. We also
report on our calculation of the non-perturbative renormalization coefficients
for these $\Delta S=1$ weak operators, using the Rome-Southampton method.

710.3415 | Modified gravity and the origin of inertia | Modified gravity theory is known to violate Birkhoff's theorem. We explore a
key consequence of this violation, the effect of distant matter in the Universe
on the motion of test particles. We find that when a particle is accelerated, a
force is experienced that is proportional to the particle's mass and
acceleration and acts in the direction opposite to that of the acceleration. We
identify this force with inertia. At very low accelerations, our inertial law
deviates slightly from that of Newton, yielding a testable prediction that may
be verified with relatively simple experiments. Our conclusions apply to all

710.3416 | A new level of photometric precision: WIRE observations of eclipsing
binary stars | The WIRE satellite was launched in March 1999 and was the first space mission
to do asteroseismology from space on a large number of stars. WIRE has produced
very high-precision photometry of a few hundred bright stars (V<6) with
temporal coverage of several weeks, including K giants, solar-like stars, delta
Scuti stars, and beta Cepheids. In the current work we will describe the status
of science done on seven detached eclipsing binary systems. Our results
emphasize some of the challenges and exciting results expected from coming
satellite missions like COROT and Kepler. Unfortunately, on 23 October 2006,
communication with WIRE failed after almost eight years in space. Because of
this sad news we will give a brief history of WIRE at the end of this paper.

710.3418 | VHE gamma-rays from Westerlund 2 and implications for the inferred
energetics | The H.E.S.S. collaboration recently reported the discovery of VHE gamma-ray
emission coincident with the young stellar cluster Westerlund 2. This system is
known to host a population of hot, massive stars, and, most particularly, the
WR binary WR20a. Particle acceleration to TeV energies in Westerlund 2 can be
accomplished in several alternative scenarios, therefore we only discuss
energetic constraints based on the total available kinetic energy in the
system, the actual mass loss rates of respective cluster members, and implied
gamma-ray production from processes such as inverse Compton scattering or

710.3419 | Moderate deviations for Poisson--Dirichlet distribution | The Poisson--Dirichlet distribution arises in many different areas. The
parameter $\theta$ in the distribution is the scaled mutation rate of a
population in the context of population genetics. The limiting case of $\theta$
approaching infinity is practically motivated and has led to new, interesting
mathematical structures. Laws of large numbers, fluctuation theorems and
large-deviation results have been established. In this paper,
moderate-deviation principles are established for the Poisson--Dirichlet
distribution, the GEM distribution, the homozygosity, and the Dirichlet process
when the parameter $\theta$ approaches infinity. These results, combined with
earlier work, not only provide a relatively complete picture of the asymptotic
behavior of the Poisson--Dirichlet distribution for large $\theta$, but also
lead to a better understanding of the large deviation problem associated with
the scaled homozygosity. They also reveal some new structures that are not
observed in existing large-deviation results.

710.342 | Time Evolution of Disease Spread on Networks with Degree Heterogeneity | Two crucial elements facilitate the understanding and control of communicable
disease spread within a social setting. These components are, the underlying
contact structure among individuals that determines the pattern of disease
transmission; and the evolution of this pattern over time. Mathematical models
of infectious diseases, which are in principle analytically tractable, use two
general approaches to incorporate these elements. The first approach, generally
known as compartmental modeling, addresses the time evolution of disease spread
at the expense of simplifying the pattern of transmission. On the other hand,
the second approach uses network theory to incorporate detailed information
pertaining to the underlying contact structure among individuals. However,
while providing accurate estimates on the final size of outbreaks/epidemics,
this approach, in its current formalism, disregards the progression of time
during outbreaks. So far, the only alternative that enables the integration of
both aspects of disease spread simultaneously has been to abandon the
analytical approach and rely on computer simulations. We offer a new analytical
framework based on percolation theory, which incorporates both the complexity
of contact network structure and the time progression of disease spread.
Furthermore, we demonstrate that this framework is equally effective on finite-
and "infinite"-size networks. Application of this formalism is not limited to
disease spread; it can be equally applied to similar percolation phenomena on
networks in other areas in science and technology.

710.3421 | Modular model building | Mathematical models are increasingly used in both academia and the
pharmaceutical industry to understand how phenotypes emerge from systems of
molecular interactions. However, their current construction as monolithic sets
of equations presents a fundamental barrier to progress. Overcoming this
requires modularity, enabling sub-systems to be specified independently and
combined incrementally, and abstraction, enabling general properties to be
specified independently of specific instances. These in turn require models to
be represented as programs rather than as datatypes. Programmable modularity
and abstraction enables libraries of modules to be created for generic
biological processes, which can be instantiated and re-used repeatedly in
different contexts with different components. We have developed a computational
infrastructure to support this. We show here why these capabilities are needed,
what is required to implement them and what can be accomplished with them that
could not be done previously.

710.3422 | A Simple Probabilistic Algorithm for Detecting Community Structure in
Social Networks | In this paper, we propose a novel semi-parametric probabilistic model which
considers interactions between different communities and can provide more
information about the network topology besides correctly detecting communities.
By using an additional parameter, our model can not only detect community
structure but also detect pattern which is a generalization of common sense
network community structure. The prior parameter in our model reveals the
characteristics of patterns inside the network. Results on some widely known
data sets prove the efficiency of our model.

710.3424 | Growth, Structure and Properties of BiFeO3-BiCrO3 Films obtained by Dual
Cross Beam PLD | The properties of epitaxial Bi2FeCrO6 thin films, recently synthesized by
pulsed laser deposition, have partially confirmed the theoretical predictions
(i.e. a magnetic moment of 2 muB per formula unit and a polarization of ~80
microC/cm2 at 0K). The existence of magnetic ordering at room temperature for
this material is an unexpected but very promising result that needs to be
further investigated. Since magnetism is assumed to arise from the exchange
interaction between the Fe and Cr cations, the magnetic behaviour is strongly
dependent on both their ordering and the distance between them. We present here
the successful synthesis of epitaxial Bi2FexCryO6 (BFCO x/y) films grown on
SrTiO3 substrates using dual crossed beam pulsed laser deposition. The crystal
structure of the films has different types of (111)-oriented superstructures
depending on the deposition conditions. The multiferroic character of BFCO
(x/y) films is proven by the presence of both ferroelectric and magnetic
hysteresis at room temperature. The oxidation state of Fe and Cr ions in the
films is shown to be 3+ only and the difference in macroscopic magnetization
with Fe/Cr ratio composition could only be due to ordering of the Cr3+ and Fe3+
cations therefore to the modification of the exchange interaction between them.

710.3425 | An entanglement measure for n-qubits | Recently, Coffman, Kundu, and Wootters introduced the residual entanglement
for three qubits to quantify the three-qubit entanglement in Phys. Rev. A 61,
052306 (2000). In Phys. Rev. A 65, 032304 (2007), we defined the residual
entanglement for $n$ qubits, whose values are between 0 and 1. In this paper,
we want to show that the residual entanglement for $n$ qubits is a natural
measure of entanglement by demonstrating the following properties. (1). It is
SL-invariant, especially LU-invariant. (2). It is an entanglement monotone.

groupoids and small categories. It contains a proof for the fact that any
groupoid is a group bundle over an equivalence relation. Moreover, the action
of a category $G$ on a category $H$ as well as the resulting semi-direct
product category $H\times_\alpha G$ will be defined (when either $G$ is a
groupoid or $H^{(0)} = G^{(0)}$). If both $G$ and $H$ are groupoids, then
$H\times_\alpha G$ is also a groupoid. The reason of producing this note is for
people who want to check some details in a recent work of Li.

710.3427 | Error Correction Capability of Column-Weight-Three LDPC Codes | In this paper, we investigate the error correction capability of
column-weight-three LDPC codes when decoded using the Gallager A algorithm. We
prove that the necessary condition for a code to correct $k \geq 5$ errors is
to avoid cycles of length up to $2k$ in its Tanner graph. As a consequence of
this result, we show that given any $\alpha>0, \exists N $ such that $\forall
n>N$, no code in the ensemble of column-weight-three codes can correct all
$\alpha n$ or fewer errors. We extend these results to the bit flipping
algorithm.

710.3428 | Shell-shocked diffusion model for the light curve of SN2006gy | We explore a simple model for the high luminosity of SN 2006gy involving
photon diffusion of shock-deposited thermal energy. The distinguishing property
of the model is that the large ``stellar'' radius of 160 AU required to prevent
adiabatic losses is not the true stellar radius, but rather, the radius of an
opaque, unbound circumstellar envelope, created when 10 Msun was ejected in the
decade before the supernova in an eruption analogous to that of eta Carinae.
The supernova light is produced primarily by diffusion of thermal energy
following the passage of the blast wave through this shell. This model differs
from traditional models of supernova debris interacting with external CSM in
that here the shell is optically thick and the escape of radiation is delayed.
We show that any model attempting to account for SN2006gy's huge luminosity
with radiation emitted by ongoing CSM interaction fails for the following basic
reason: the CSM density required to achieve the observed luminosity makes the
same circumstellar envelope opaque, forcing a thermal diffusion solution. In
our model, the weaker CSM interaction giving rise to SN2006gy's characteristic
Type IIn spectrum and soft X-rays is not linked to the power source of the
visual continuum; instead, it arises after the blast wave breaks free of the
opaque shell into the surrounding wind. While a simple diffusion model can
explain the gross properties of the early light curve of SN2006gy, it predicts
that the light curve must plummet rapidly at late-times, unless an additional
power source is present.

710.3429 | Axion Inflation and Gravity Waves in String Theory | The majority of models of inflation in string theory predict an absence of
measurable gravitational waves, r << 10^{-3}. The most promising proposals for
making string theoretic models that yield measurable tensor fluctuations
involve axion fields with slightly broken shift symmetry. We consider such
models in detail, with a particular focus on the N-flation scenario and on
axion valley/natural inflation models. We find that in Calabi-Yau threefold
compactifications with logarithmic Kahler potentials K it appears to be
difficult to meet the conditions required for axion inflation in the
supergravity regime. However, in supergravities with an (approximately)
quadratic shift-symmetric K, axion inflation may be viable. Such Kahler
potentials do arise in some string models, in specific limits of the moduli
space. We describe the most promising classes of models; more detailed study
will be required before one can conclude that working models exist.

constraints include the large observed mass-loss rates in LBV eruptions, the
large masses of evolved massive stars like LBVs and WNH stars, WR stars in
lower metallicity environments, observed rotation rates of massive stars at
different metallicity, supernovae that seem to defy expectations of high
mass-loss rates in stellar evolution, and other clues. I pay particular
attention to the role of feedback that would result from higher mass-loss
rates, driving the star to the Eddington limit too particular attention to the
role of feedback that would result from higher mass-loss rates, driving the
star to the Eddington limit too soon, and therefore making higher rates appear

710.3431 | Possible Detection of a Pair Instability Supernova in the Modern
Universe, and Implications for the First Stars | SN 2006gy radiated far more energy in visual light than any other supernova
so far, and potential explanations for its energy demands have implications for
galactic chemical evolution and the deaths of the first stars. It remained
bright for over 200 days, longer than any normal supernova, and it radiated
more than 1e51 ergs of luminous energy at visual wavelengths. I argue that this
Type IIn supernova was probably the explosion of an extremely massive star like
Eta Carinae that retained its hydrogen envelope when it exploded, having
suffered relatively little mass loss during its lifetime. That this occurred at
roughly Solar metallicity challenges current paradigms for mass loss in
massive-star evolution. I explore a few potential explanations for SN2006gy's
power source, involving either circumstellar interaction, or instead, the decay
of 56Ni. If SN 2006gy was powered by the conversion of shock energy into light,
then the conditions must be truly extraordinary and traditional interaction
models don't work. If SN 2006gy was powered by radioactive decay, then the
uncomfortably huge 56Ni mass requires that the star exploded as a pair
instability supernova. The mere possibility of this makes SN 2006gy
interesting, especially at this meeting, because it is the first good candidate
for a genuine pair instability supernova.

710.3432 | SU(5) grand unification on a domain-wall brane from an E_6-invariant
action | An SU(5) grand unification scheme for effective 3+1-dimensional fields
dynamically localised on a domain-wall brane is constructed. This is achieved
through the confluence of the clash-of-symmetries mechanism for symmetry
breaking through domain-wall formation, and the Dvali-Shifman gauge-boson
localisation idea. It requires an E_6 gauge-invariant action, yielding a
domain-wall solution that has E_6 broken to differently embedded SO(10) x U(1)
subgroups in the two bulk regions on opposite sides of the wall. On the wall
itself, the unbroken symmetry is the intersection of the two bulk subgroups,
and contains SU(5). A 4+1-dimensional fermion family in the 27 of E_6 gives
rise to localised left-handed zero-modes in the 5^* + 10 + 1 + 1 representation
of SU(5). The remaining ten fermion components of the 27 are delocalised exotic
states, not appearing in the effective 3+1-dimensional theory on the

710.3433 | Phase behavior and dynamics of a micelle-forming triblock copolymer
system | Synperonic F-108 (generic name, 'pluronic') is a micelle forming triblock
copolymer of type ABA, where A is polyethylene oxide (PEO) and B is
polypropylene oxide (PPO). At high temperatures, the hydrophobicity of the PPO
chains increase, and the pluronic molecules, when dissolved in an aqueous
medium, self-associate into spherical micelles with dense PPO cores and
hydrated PEO coronas. At appropriately high concentrations, these micelles
arrange in a face centred cubic lattice to show inverse crystallization, with
the samples exhibiting high-temperature crystalline and low-temperature
fluidlike phases. By studying the evolution of the elastic and viscous moduli
as temperature is increased at a fixed rate, we construct the
concentration-temperature phase diagram of Synperonic F-108. For a certain
range of temperatures and at appropriate sample concentrations, we observe a
predominantly elastic response. Oscillatory strain amplitude sweep measurements
on these samples show pronounced peaks in the loss moduli, a typical feature of
soft solids. The soft solid-like nature of these materials is further
demonstrated by measuring their frequency dependent mechanical moduli. The
storage moduli are significantly larger than the loss moduli and are almost
independent of the applied angular frequency. Finally, we perform strain rate
frequency superposition (SRFS) experiments to measure the slow relaxation
dynamics of this soft solid.

710.3435 | Numerical experimentation within GRworkbench | The software tool GRworkbench is an ongoing project in visual, numerical
General Relativity at The Australian National University. This year,
GRworkbench has been significantly extended to facilitate numerical
experimentation. The numerical differential geometric engine has been rewritten
using functional programming techniques, enabling fundamental concepts to be
directly represented as variables in the C++ code of GRworkbench. Sophisticated
general numerical methods have replaced simpler specialised algorithms. Various
tools for numerical experimentation have been implemented, allowing for the
simulation of complex physical situations.
A recent claim, that the mass of the Milky Way can be measured using a small
interferometer located on the surface of the Earth, has been investigated, and
found to be an artifact of the approximations employed in the analysis. This
difficulty is symptomatic of the limitations of traditional pen-and-paper
analysis in General Relativity, which was the motivation behind the original
development of GRworkbench. The physical situation pertaining to the claim has
been modelled in a numerical experiment in GRworkbench, without the necessity
of making any simplifying assumptions, and an accurate estimate of the effect
has been obtained.

710.3436 | Spontaneous Emergence of Modularity in a Model of Evolving Individuals | We investigate the selective forces that promote the emergence of modularity
in nature. We demonstrate the spontaneous emergence of modularity in a
population of individuals that evolve in a changing environment. We show that
the level of modularity correlates with the rapidity and severity of
environmental change. The modularity arises as a synergistic response to the
noise in the environment in the presence of horizontal gene transfer. We
suggest that the hierarchical structure observed in the natural world may be a
broken symmetry state, which generically results from evolution in a changing

First-Principles Calculations | The full-potential linear augmented plane-wave calculations have been applied
to investigate the systematic change of electronic structures in CaAlSi due to
different stacking sequences of AlSi layers. The present ab-initio calculations
have revealed that the multistacking, buckling and 60 degrees rotation of AlSi
layer affect the electronic band structure in this system. In particular, such
a structural perturbation gives rise to the disconnected and cylindrical Fermi
surface along the M-L lines of the hexagonal Brillouin zone. This means that
multistacked CaAlSi with the buckling AlSi layers increases degree of
two-dimensional electronic characters, and it gives us qualitative
understanding for the quite different upper critical field anisotropy between
specimens with and without superstructure as reported previously.

710.3439 | Utility-Based Wireless Resource Allocation for Variable Rate
Transmission | For most wireless services with variable rate transmission, both average rate
and rate oscillation are important performance metrics. The traditional
performance criterion, utility of average transmission rate, boosts the average
rate but also results in high rate oscillations. We introduce a utility
function of instantaneous transmission rates. It is capable of facilitating the
resource allocation with flexible combinations of average rate and rate
oscillation. Based on the new utility, we consider the time and power
allocation in a time-shared wireless network. Two adaptation policies are
developed, namely, time sharing (TS) and joint time sharing and power control
(JTPC). An extension to quantized time sharing with limited channel feedback
(QTSL) for practical systems is also discussed. Simulation results show that by

710.344 | Five-dimensional Superfield Supergravity | We present a projective superspace formulation for matter-coupled simple
supergravity in five dimensions. Our starting point is the superspace
realization for the minimal supergravity multiplet proposed by Howe in 1981. We
introduce various off-shell supermultiplets (i.e. hypermultiplets, tensor and
vector multiplets) that describe matter fields coupled to supergravity. A
projective-invariant action principle is given, and specific dynamical systems
are constructed including supersymmetric nonlinear sigma-models. We believe
that this approach can be extended to other supergravity theories with eight
supercharges in $D\leq 6$ space-time dimensions, including the important case
of 4D N=2 supergravity.

710.3441 | Electron - nuclear recoil discrimination by pulse shape analysis | In the framework of the ``ULTIMA'' project, we use ultra cold superfluid 3He
bolometers for the direct detection of single particle events, aimed for a
future use as a dark matter detector. One parameter of the pulse shape observed
after such an event is the thermalization time constant. Until now it was
believed that this parameter only depends on geometrical factors and superfluid
3He properties, and that it is independent of the nature of the incident
particles. In this report we show new results which demonstrate that a
difference for muon- and neutron events, as well as events simulated by heater

paper first proposes a formal modeling of the electrical signature of QDI

identify the source of leakage of this type of circuits. Finally, a complete

710.3444 | Strangeness Content of the Nucleon in the \chiCQM_{config} | Several parameters characterizing the strangeness content of the nucleon have
been calculated in the chiral constituent quark model with configuration mixing
(\chiCQM_{config}) which is known to provide a satisfactory explanation of the
``proton spin problem'' and related issues. In particular, we have calculated
the strange spin polarization \Delta s, the strangeness contribution to the
weak axial vector couplings \Delta_8 etc., strangeness contribution to the
magnetic moments \mu(p)^s etc., the strange quark flavor fraction f_s, the
strangeness dependent quark ratios \frac{2 \bar s}{u+d} and \frac{2 \bar

710.3445 | Vacuum densities for a thick brane in AdS spacetime | For a massive scalar field with general curvature coupling parameter we
evaluate Wightman function, vacuum expectation values of the field square and
the energy-momentum tensor induced by a $Z_{2}$-symmetric brane with finite
thickness located on $(D+1)$-dimensional AdS bulk. For the general case of
static plane symmetric interior structure the expectation values in the region
outside the brane are presented as the sum of free AdS and brane induced parts.
For a conformally coupled massless scalar the brane induced part in the vacuum
energy-momentum tensor vanishes. In the limit of strong gravitational fields
the brane induced parts are exponentially suppressed for points not too close
to the brane boundary. As an application of general results a special model is
considered in which the geometry inside the brane is a slice of the Minkowski
spacetime orbifolded along the direction perpendicular to the brane. For this
model the Wightman function, vacuum expectation values of the field square and
the energy-momentum tensor inside the brane are evaluated. It is shown that for
both minimally and conformally coupled scalar fields the interior vacuum forces
acting on the brane boundaries tend to decrease the brane thickness.

710.3446 | Conformal Invariance for Certain Models of the Bond-Triangular Type | Following the approach outlined in [18], convergence to SLE6 of the
Exploration Processes for the correlated bond-triangular type models studied in
[7] is established. This puts the said models in the same universality class as
the standard site percolation model on the triangular lattice [19]. The result
is proven for all domains with boundary (upper) Minkowski dimension less than
two. Moreover, the proof of convergence applies in the general context of

710.3449 | New non-abelian effects on D branes | We extend the Myers dielectric effect to configurations with angular
momentum. The resulting time-dependent N D0 brane bound states can be
interpreted as describing rotating fuzzy ellipsoids. A similar solution exists
also in the presence of a RR magnetic field, that we study in detail. We show
that, for any finite N, above a certain critical angular momentum is
energetically more favorable for the bound state system to dissociate into an
abelian configuration of N D0 branes moving independently. We have investigated
this problem in the low-energy expansion of the non-abelian D brane action for
generic N. In the case N=2 we find explicit solutions of the full non-abelian
Born-Infeld D brane dynamics, which remarkably have the same structure and
confirm the features of the low-energy approximation. We further study D string

710.345 | Spin up and phase fluctuations in the timing of the accreting
millisecond pulsar XTE J1807-294 | We performed a timing analysis of the 2003 outburst of the accreting X-ray
millisecond pulsar XTE J1807-294 observed by RXTE. Using recently refined
orbital parameters we report for the first time a precise estimate of the spin
frequency and of the spin frequency derivative. The phase delays of the pulse
profile show a strong erratic behavior superposed to what appears as a global
spin-up trend. The erratic behavior of the pulse phases is strongly related to
rapid variations of the light curve, making it very difficult to fit these
phase delays with a simple law. As in previous cases, we have therefore
analyzed separately the phase delays of the first harmonic and of the second
harmonic of the spin frequency, finding that the phases of the second harmonic
are far less affected by the erratic behavior. In the hypothesis that the
second harmonic pulse phase delays are a good tracer of the spin frequency
evolution we give for the first time a estimation of the spin frequency
derivative in this source. The source shows a clear spin-up of $\dot \nu =
2.5(7) \times 10^{-14}$ Hz sec$^{-1}$ (1 $\sigma$ confidence level). The
largest source of uncertainty in the value of the spin-up rate is given by the
uncertainties on the source position in the sky. We discuss this systematics on
the spin frequency and its derivative.

710.3451 | Comlexity of prime-dimensional sequences over a finite field | V.I. Arnold has recently defined the complexity of a sequence of $n$ zeros
and ones with the help of the operator of finite differences. In this paper we
describe the results obtained for almost most complicated sequences of elements
of a finite field, whose dimension $n$ is a prime number. We prove that with
$n\to \infty$ this property is inherent in almost all sequences, while the
values of multiplicative functions possess this property with any $n$ different
from the characteristic of the field. We also describe the prime values of the
parameter $n$ which make the logarithmic function almost most complicated. All
these sequences reveal a stronger complexity; its algebraic sense is quite
clear.
