709.0135 | An improved solar wind electron-density model for pulsar timing | Variations in the solar wind density introduce variable delays into pulsar
timing observations. Current pulsar timing analysis programs only implement
simple models of the solar wind, which not only limit the timing accuracy, but
can also affect measurements of pulsar rotational, astrometric and orbital
parameters. We describe a new model of the solar wind electron density content
which uses observations from the Wilcox Solar Observatory of the solar magnetic
field. We have implemented this model into the tempo2 pulsar timing package. We
show that this model is more accurate than previous models and that these
corrections are necessary for high precision pulsar timing applications.

709.0137 | Hadronic charmless B decays B-> AP | The two-body hadronic decays of B mesons into pseudoscalar and axial vector
mesons are studied within the framework of QCD factorization. The light-cone
distribution amplitudes (LCDAs) for $^3P_1$ and $^1P_1$ axial-vector mesons
have been evaluated using the QCD sum rule method. Owing to the G-parity, the
chiral-even two-parton light-cone distribution amplitudes of the $^3P_1$
($^1P_1$) mesons are symmetric (antisymmetric) under the exchange of quark and
anti-quark momentum fractions in the SU(3) limit. For chiral-odd LCDAs, it is
other way around. The main results are the following: (i) The predicted rates
for $a_1^\pm(1260)\pi^\mp$, $b_1^\pm(1235)\pi^\mp$, $b_1^0(1235)\pi^-$,
$a_1^+K^-$ and $b_1^+K^-$ modes are in good agreement with the data. However,
the naively expected ratios $Br(B^-\to a_1^0\pi^-)/Br(\ov B^0\to
a_1^+\pi^-)\leq 1$, $Br(B^-\to a_1^-\pi^0)/Br(\ov B^0\to a_1^-\pi^+)\sim
{1\over 2}$ and $Br(B^-\to b_1^0K^-)/Br(\ov B^0\to b_1^+K^-)\sim {1\over 2}$
are not borne out by experiment. This should be clarified by the improved
measurements of these decays. (ii) Since the $\bar B\to b_1K$ decays receive
sizable annihilation contributions, their rates are sensitive to the
interference between penguin and annihilation terms. The measurement of
$Br(\bar B^0\to b_1^+K^-)$ implies a destructive interference which in turn
indicates that the form factors for $B\to b_1$ and $B\to a_1$ transitions are
of opposite signs. (iii) Sizable power corrections such as weak annihilation
are needed to account for the observed rates of the penguin-dominated modes
$K_1^-(1270)\pi^+$ and $K_1^-(1400)\pi^+$.

709.0138 | Feature selection for high dimensional data in astronomy | With an exponentially increasing amount of astronomical data, the complexity
and dimension of astronomical data are likewise growing rapidly. Extracting
information from such data becomes a critical and challenging problem. For
example, some algorithms can only be employed in the low-dimensional spaces, so
feature selection and feature extraction become important topics. Here we
describe the difference between feature selection and feature extraction
methods, and introduce the taxonomy of feature selection methods as well as the
characteristics of each method. We present a case study comparing the
performance and computational cost of different feature selection methods. For
the filter method, ReliefF and fisher filter are adopted; for the wrapper
method, improved CHAID, linear discriminant analysis (LDA), Naive Bayes (NB)
and C4.5 are taken as learners. Applied on the sample, the result indicates
that from the viewpoints of computational cost the filter method is superior to
the wrapper method. Moreover, different learning algorithms combined with
appropriate feature selection methods may arrive at better performance.

709.0139 | Non-Regular Likelihood Inference for Seasonally Persistent Processes | The estimation of parameters in the frequency spectrum of a seasonally
persistent stationary stochastic process is addressed. For seasonal persistence
associated with a pole in the spectrum located away from frequency zero, a new
Whittle-type likelihood is developed that explicitly acknowledges the location
of the pole. This Whittle likelihood is a large sample approximation to the
distribution of the periodogram over a chosen grid of frequencies, and
constitutes an approximation to the time-domain likelihood of the data, via the
linear transformation of an inverse discrete Fourier transform combined with a
demodulation. The new likelihood is straightforward to compute, and as will be
demonstrated has good, yet non-standard, properties. The asymptotic behaviour
of the proposed likelihood estimators is studied; in particular,
$N$-consistency of the estimator of the spectral pole location is established.
Large finite sample and asymptotic distributions of the score and observed
Fisher information are given, and the corresponding distributions of the
maximum likelihood estimators are deduced. A study of the small sample
properties of the likelihood approximation is provided, and its superior
performance to previously suggested methods is shown, as well as agreement with
the developed distributional approximations.

709.014 | Perturbation Theory of Coulomb Gauge Yang-Mills Theory Within the First
Order Formalism | Perturbative Coulomb gauge Yang-Mills theory within the first order formalism
is considered. Using a differential equation technique and dimensional
regularization, analytic results for both the ultraviolet divergent and finite
parts of the two-point functions at one-loop order are derived. It is shown how
the non-ultraviolet divergent parts of the results are finite at spacelike

709.0143 | The Existence of Inner Cool Disks in the Low Hard State of Accreting
Black Holes | The condensation of matter from a corona to a cool, optically thick inner
disk is investigated for black hole X-ray transient systems in the low hard
state. A description of a simple model for the exchange of energy and mass
between corona and disk originating from thermal conduction is presented,
taking into account the effect of Compton cooling of the corona by photons from
the underlying disk. It is found that a weak, condensation-fed inner disk can
be present in the low hard state of black hole transient systems for a range of
luminosities which depend on the magnitude of the viscosity parameter. For
$\alpha \sim 0.1-0.4$ an inner disk can exist for luminosities in the range
$\sim 0.001- 0.02$ Eddington value. The model is applied to the X-ray
observations of the black hole candidate sources GX 339-4 and Swift
J1753.5-0127 in their low hard state. It is found that Compton cooling is
important in the condensation process, leading to the maintenance of cool inner
disks in both systems. As the results of the evaporation/condensation model are
independent of the black hole mass, it is suggested that such inner cool disks
may contribute to the optical and ultraviolet emission of low luminosity active
galactic nuclei.

709.0144 | The thermodynamics for a hadronic gas of fireballs with internal color
structures and chiral fields | The thermodynamical partition function for a gas of color-singlet bags
consisting of fundamental and adjoint particles in both $U(N_c)$ and $SU(N_c)$
group representations is reviewed in detail. The constituent particle species
are assumed to satisfy various thermodynamical statistics. The gas of bags is
probed to study the phase transition for a nuclear matter in the extreme
conditions. These bags are interpreted as the Hagedorn states and they are the
highly excited hadronic states which are produced below the phase transition
point to the quark-gluon plasma. The hadronic density of states has the
Gross-Witten critical point and exhibits a third order phase transition from a
hadronic phase dominated by the discrete low-lying hadronic mass spectrum
particles to another hadronic phase dominated by the continuous Hagedorn
states. The Hagedorn threshold production is found just above the highest known
experimental discrete low-lying hadronic mass spectrum. The subsequent Hagedorn
phase undergoes a first order deconfinement phase transition to an explosive
quark-gluon plasma. The role of the chiral phase transition in the phases of
the discrete low-lying mass spectrum and the continuous Hagedorn mass spectrum
is also considered. It is found crucial in the phase transition diagram.
Alternate scenarios are briefly discussed for the Hagedorn gas undergoes a
higher order phase transition through multi-processes of internal color-flavor
structure modification.

709.0145 | Estimating Random Variables from Random Sparse Observations | Let X_1,...., X_n be a collection of iid discrete random variables, and
Y_1,..., Y_m a set of noisy observations of such variables. Assume each
observation Y_a to be a random function of some a random subset of the X_i's,
and consider the conditional distribution of X_i given the observations, namely
\mu_i(x_i)\equiv\prob\{X_i=x_i|Y\} (a posteriori probability).
We establish a general relation between the distribution of \mu_i, and the
fixed points of the associated density evolution operator. Such relation holds
asymptotically in the large system limit, provided the average number of
variables an observation depends on is bounded. We discuss the relevance of our

709.0148 | Entanglement of Accelerating Particles | We study how the entanglement of a maximally entangled pair of particles is
affected when one or both of the pair are uniformly accelerated, while the
detector remains in an inertial frame. We find that the entanglement is
unchanged if all degrees of freedom are considered. However, particle pairs are
produced, and the entanglements of different bipartite systems may change with
the acceleration. In particular, the entanglement between accelerating fermions
is transferred preferentially to the produced antiparticles when the
acceleration is large, and the entanglement transfer is complete when the

entanglement transfer to the antiparticles is observed.

709.0149 | Blackbody radiation shift in a 43Ca+ ion optical frequency standard | Motivated by the prospect of an optical frequency standard based on 43Ca+, we
calculate the blackbody radiation (BBR) shift of the 4s_1/2-3d_5/2 clock
transition, which is a major component of the uncertainty budget. The
calculations are based on the relativistic all-order single-double method where
all single and double excitations of the Dirac-Fock wave function are included
to all orders of perturbation theory. Additional calculations are conducted for
the dominant contributions in order to evaluate some omitted high-order
corrections and estimate the uncertainties of the final results. The BBR shift
obtained for this transition is 0.38(1) Hz. The tensor polarizability of the
3d_5/2 level is also calculated and its uncertainty is evaluated as well. Our
results are compared with other calculations.

709.015 | Realizability and exceptionality of candidate surface branched covers:
methods and results | Given two closed orientable surfaces, the Hurwitz existence problem asks
whether there exists a branched cover between them having prescribed global
degree and local degrees over the branching points. The Riemann-Hurwitz formula
gives a necessary condition, which was shown to be also sufficient when the
base surface has positive genus. For the sphere one knows that for some data
the cover exists and for some it does not, but the problem is still open in
general. In this paper we will review five different techniques recently
employed to attack it, and we will state the main results they have led to. To
illustrate the techniques we will give five independent proofs of the fact that
there is no branched cover of the sphere over itself with degree 4, three

709.0152 | Do Nonequilibrium Processes Have Features in Common? | The nature takes the easiest and most accessible paths and, hence, processes
are accomplished very quickly in a minimum time. In 1662 P. Fermat used this
principle to work out the refraction law. This was one of the first known
attempts at successful deductive description of a physical phenomenon involving
the variational principle. Presently researchers concerned with nonequilibrium
processes have turned back to Fermat's idea in the form of the maximum entropy
production principle (MEPP). MEPP has proved to be good for understanding and
description of diverse nonequilibrium processes in physics, chemistry and

709.0153 | Optical vortex coronagraphs on ground-based telescopes | The optical vortex coronagraph is potentially a remarkably effective device,
at least for an ideal unobstructed telescope. Most ground-based telescopes
however suffer from central obscuration and also have to operate through the
aberrations of the turbulent atmosphere. This note analyzes the performance of
the optical vortex in these circumstances and compares to some other designs,
showing that it performs similarly in this situation. There is a large class of
coronagraphs of this general type, and choosing between them in particular
applications depends on details of performance at small off-axis distances and
uniformity of response in the focal plane. Issues of manufacturability to the
necessary tolerances are also likely to be important.

709.0155 | Transition Phenomena Induced by Internal Noise and Quasi-absorbing State | We study a simple chemical reaction system and effects of the internal noise.
The chemical reaction system causes the same transition phenomenon discussed by
Togashi and Kaneko [Phys. Rev. Lett. 86 (2001) 2459; J. Phys. Soc. Jpn. 72
(2003) 62]. By using the simpler model than Togashi-Kaneko's one, we discuss
the transition phenomenon by means of a random walk model and an effective
model. The discussion makes it clear that quasi-absorbing states, which are
produced by the change of the strength of the internal noise, play an important
role in the transition phenomenon. Stabilizing the quasi-absorbing states

709.0157 | The effect of partonic wind on charm quark correlations in high-energy
nuclear collisions | In high-energy collisions, massive heavy quarks are produced back-to-back
initially and they are sensitive to early dynamical conditions. The strong
collective partonic wind from the fast expanding quark-gluon plasma created in
high-energy nuclear collisions modifies the correlation pattern significantly.
As a result, the angular correlation function for D$\bar{\rm D}$ pairs is
suppressed at the angle $\Delta\phi=\pi$. While the hot and dense medium in
collisions at RHIC ($\sqrt{s_{NN}}=200$ GeV) can only smear the initial
back-to-back D$\bar {\rm D}$ correlation, a clear and strong near side
D$\bar{\rm D}$ correlation is expected at LHC ($\sqrt{s_{NN}}=5500$ GeV).

709.0158 | The Christoffel problem and two analogs of the Minkowski problem in
Riemannian space | Author finds the solutions of the Christoffel problem for open and closed
surfaces in Riemannian space. The Christoffel problem is reduced to the problem
of construction the continuous G-deformations preserving the sum of principal
radii of curvature for every point of surface in Riemannian space.
G-deformation transfers every normal vector of surface in parallel along the
path of the translation for each point of surface. The following analogs of the
Minkowski problem for open and closed surfaces in Riemannian space are being
considered in this article: 1) the problem of construction the surface with
prescribed mean curvature and condition of G-deformation; 2) the problem of

709.0159 | An empirical behavioral model of liquidity and volatility | We develop a behavioral model for liquidity and volatility based on empirical
regularities in trading order flow in the London Stock Exchange. This can be
viewed as a very simple agent based model in which all components of the model
are validated against real data. Our empirical studies of order flow uncover
several interesting regularities in the way trading orders are placed and
cancelled. The resulting simple model of order flow is used to simulate price
formation under a continuous double auction, and the statistical properties of
the resulting simulated sequence of prices are compared to those of real data.
The model is constructed using one stock (AZN) and tested on 24 other stocks.
For low volatility, small tick size stocks (called Group I) the predictions are
very good, but for stocks outside Group I they are not good. For Group I, the
model predicts the correct magnitude and functional form of the distribution of
the volatility and the bid-ask spread, without adjusting any parameters based
on prices. This suggests that at least for Group I stocks, the volatility and
heavy tails of prices are related to market microstructure effects, and
supports the hypothesis that, at least on short time scales, the large
fluctuations of absolute returns are well described by a power law with an
exponent that varies from stock to stock.

709.016 | The Lunar Cherenkov Technique: From Parkes Onwards | The lunar Cherenkov technique, which aims to detect the coherent Cherenkov
radiation produced when UHE particles interact in the lunar regolith, was first
attempted with the Parkes radio-telescope in 1995, though the theory was not
sufficiently developed at this time to calculate a limit on the UHE neutrino
flux from the non-observation. Since then, the technique has evolved to include
experiments utilising lower frequencies, wider bandwidths, and entire arrays of
antenna. We develop a simulation to analyse the full range of experiments, and
calculate the UHE neutrino flux limit from the Parkes experiment, including the
directional dependence. Our results suggest a methodology for planning future

709.0161 | Integral equation for gauge invariant quark two-point Green's function
in QCD | Gauge invariant quark two-point Green's functions defined with path-ordered
gluon field phase factors along skew-polygonal lines joining the quark to the
antiquark are considered. Functional relations between Green's functions with
different numbers of path segments are established. An integral equation is
obtained for the Green's function defined with a phase factor along a single
straight line. The equation implicates an infinite series of two-point Green's
functions, having an increasing number of path segments; the related kernels
involve Wilson loops with contours corresponding to the skew-polygonal lines of
the accompanying Green's function and with functional derivatives along the
sides of the contours. The series can be viewed as an expansion in terms of the
global number of the functional derivatives of the Wilson loops. The
lowest-order kernel, which involves a Wilson loop with two functional
derivatives, provides the framework for an approximate resolution of the
equation.

709.0162 | Trotter Derivation of Algorithms for Brownian and Dissipative Particle
Dynamics | This paper focuses on the temporal discretization of the Langevin dynamics,
and on different resulting numerical integration schemes. Using a method based
on the exponentiation of time dependent operators, we carefully derive a
numerical scheme for the Langevin dynamics, that we found equivalent to the
proposal of Ermak, and not simply to the stochastic version of the
velocity-Verlet algorithm. However, we checked on numerical simulations that
both algorithms give similar results, and share the same ``weak order two''
accuracy. We then apply the same strategy to derive and test two numerical
schemes for the dissipative particle dynamics (DPD). The first one of them was

709.0163 | Induced gravity and entanglement entropy of 2D black holes | Using the fact that 2D Newton constant is wholly induced by a conformal field
theory, we derive a formula for the entanglement entropy of the anti-de Sitter
black hole in two spacetime dimensions. The leading term in the large black
hole mass expansion of our formula reproduces exactly the Bekenstein-Hawking
entropy S_{BH}, whereas the subleading term behaves as ln S_{BH}. This
subleading term has the universal form typical for the entanglement entropy of
physical systems described by effective conformal fields theories (e.g.
one-dimensional statistical models at the critical point).

709.0164 | Magnetic Ordering of Nuclear Spins in an Interacting 2D Electron Gas | We investigate the magnetic behavior of nuclear spins embedded in a 2D
interacting electron gas using a Kondo lattice model description. We derive an
effective magnetic Hamiltonian for the nuclear spins which is of the RKKY type
and where the interactions between the nuclear spins are strongly modified by
the electron-electron interactions. We show that the nuclear magnetic ordering
at finite temperature relies on the (anomalous) behavior of the 2D static
electron spin susceptibility, and thus provides a connection between
low-dimensional magnetism and non-analyticities in interacting 2D electron
systems. Using various perturbative and non-perturbative approximation schemes
in order to establish the general shape of the electron spin susceptibility as
function of its wave vector, we show that the nuclear spins locally order
ferromagnetically, and that this ordering can become global in certain regimes
of interest. We demonstrate that the associated Curie temperature for the

709.0165 | Of mice and men: Sparse statistical modeling in cardiovascular genomics | In high-throughput genomics, large-scale designed experiments are becoming
common, and analysis approaches based on highly multivariate regression and
anova concepts are key tools. Shrinkage models of one form or another can
provide comprehensive approaches to the problems of simultaneous inference that
involve implicit multiple comparisons over the many, many parameters
representing effects of design factors and covariates. We use such approaches
here in a study of cardiovascular genomics. The primary experimental context
concerns a carefully designed, and rich, gene expression study focused on
gene-environment interactions, with the goals of identifying genes implicated
in connection with disease states and known risk factors, and in generating
expression signatures as proxies for such risk factors. A coupled exploratory
analysis investigates cross-species extrapolation of gene expression
signatures--how these mouse-model signatures translate to humans. The latter
involves exploration of sparse latent factor analysis of human observational
data and of how it relates to projected risk signatures derived in the animal
models. The study also highlights a range of applied statistical and genomic
data analysis issues, including model specification, computational questions
and model-based correction of experimental artifacts in DNA microarray data.

709.0166 | Constraining Dark Matter hypothesis through Diffuse Source observations
with the GLAST-LAT detector | The Gamma-Ray Large Area Space Telescope (GLAST), scheduled to be launched in
Fall 2007, is a next generation high energy gamma-ray observatory. The Large
Area Telescope (LAT) instrument on-board GLAST with a wide field of view ($>$ 2
sr), large effective area and 20 MeV to $>$300 GeV energy range, will provide
excellent opportunity for future Dark Matter studies. We present an overview of
the GLAST Dark Matter and New Physics Working Group efforts in the study of the
LAT capability to detect a gamma-ray flux coming from WIMP pair annihilations
in diffuse astrophysical sources. Particular attention will be given to

709.0167 | Covariant anomaly and Hawking radiation from the modified black hole in
the rainbow gravity theory | Recently, Banerjee and Kulkarni (R. Banerjee, S. Kulkarni, arXiv:0707.2449
[hep-th]) suggested that it is conceptually clean and economical to use only
the covariant anomaly to derive Hawking radiation from a black hole. Based upon
this simplified formalism, we apply the covariant anomaly cancellation method
to investigate Hawking radiation from a modified Schwarzschild black hole in
the theory of rainbow gravity. Hawking temperature of the gravity's rainbow
black hole is derived from the energy-momentum flux by requiring it to cancel
the covariant gravitational anomaly at the horizon. We stress that this
temperature is exactly the same as that calculated by the method of cancelling
the consistent anomaly.

709.0168 | Gravitational waves from 3D MHD core collapse simulations | We present the gravitational wave analysis from rotating (model s15g) and
nearly non-rotating (model s15h) 3D MHD core collapse supernova simulations at
bounce and the first couple of ten milliseconds afterwards. The simulations are
launched from 15M_{\odot} progenitor models stemming from stellar evolution
calculations. Gravity is implemented by a spherically symmetric effective
general relativistic potential. The input physics uses the Lattimer-Swesty
equation of state for hot, dense matter and a neutrino parametrisation scheme
that is accurate until the first few ms after bounce. The 3D simulations allow
us to study features already known from 2D simulations as well as
nonaxisymmetric effects. In agreement with recent results we find only type I
gravitational wave signals at core bounce. In the later stage of the
simulations, one of our models (s15g) shows nonaxisymmetric gravitational wave
emission caused by a low T/|W| dynamical instability, while the other model
radiates gravitational waves due to a convective instability in the
protoneutron star. The total energy released in gravitational waves within the
considered time intervals is 1.52\times10^{-7}M_{\odot} (s15g) and
4.72\times10^{-10}M_{\odot} (s15h). Both core collapse simulations indicate
that corresponding events in our Galaxy would be detectable either by the LIGO
or Advanced LIGO detector.

hydrogen towards HH91A | Integral-field spectroscopy of molecular hydrogen in the optical wavelength
region and complementary long-slit near-infrared spectroscopy are presented
towards HH91A.The detection of some 200 H_2 lines arising from ro-vibrational
levels up to v'=8 ranging between 7700A and 2.3 microns is reported. The
emission arises from thermally excited gas where the bulk of the material is at
2750 K and where 1% is at 6000 K. The total column density of shocked gas is
N(H_2) = 10^{18} cm^{-2}. Non-thermal excitation scenarios such as
UV-fluorescence do not contribute to the excitation of H_2 towards HH91A. The
emission is explained in terms of a slow non-dissociative J-shock which
propagates into a low-density medium which has been swept-up by previous
episodes of outflows which have occurred in the evolved HH90/91 complex.

709.017 | Untangling a Planar Graph | A straight-line drawing $\delta$ of a planar graph $G$ need not be plane, but
can be made so by \emph{untangling} it, that is, by moving some of the vertices
of $G$. Let shift$(G,\delta)$ denote the minimum number of vertices that need
to be moved to untangle $\delta$. We show that shift$(G,\delta)$ is NP-hard to
compute and to approximate. Our hardness results extend to a version of
\textsc{1BendPointSetEmbeddability}, a well-known graph-drawing problem.
Further we define fix$(G,\delta)=n-shift(G,\delta)$ to be the maximum number
of vertices of a planar $n$-vertex graph $G$ that can be fixed when untangling
$\delta$. We give an algorithm that fixes at least $\sqrt{((\log n)-1)/\log
\log n}$ vertices when untangling a drawing of an $n$-vertex graph $G$. If $G$
is outerplanar, the same algorithm fixes at least $\sqrt{n/2}$ vertices. On the
other hand we construct, for arbitrarily large $n$, an $n$-vertex planar graph
$G$ and a drawing $\delta_G$ of $G$ with fix$(G,\delta_G) \le \sqrt{n-2}+1$ and
an $n$-vertex outerplanar graph $H$ and a drawing $\delta_H$ of $H$ with
fix$(H,\delta_H) \le 2 \sqrt{n-1}+1$. Thus our algorithm is asymptotically
worst-case optimal for outerplanar graphs.

709.0171 | Quark motional effects on the interquark potential in baryons | We study the heavy-heavy-light quark ($QQq$) system in a non-relativistic
potential model, and investigate the quark motional effect on the
inter-two-quark potential in baryons. We adopt the Hamiltonian with the static
three-quark potential which is obtained by the first-principle calculation of
lattice QCD, rather than the two-body force in ordinary quark models. Using the
renormalization-group inspired variational method in discretized space, we
calculate the ground-state energy of $QQq$ systems and the light-quark spatial
distribution. We find that the effective string tension between the two heavy
quarks is reduced compared to the static three-quark case. This reduction of
the effective string tension originates from the geometrical difference between

709.0172 | Improving the consensus performance via predictive mechanisms | Considering some predictive mechanisms, we show that ultrafast
average-consensus can be achieved in networks of interconnected agents. More
specifically, by predicting the dynamics of the network several steps ahead and
using this information in the design of the consensus protocol of each agent,
drastic improvements can be achieved in terms of the speed of consensus
convergence, without changing the topology of the network. Moreover, using
these predictive mechanisms, the range of sampling periods leading to consensus
convergence is greatly expanded compared with the routine consensus protocol.
This study provides a mathematical basis for the idea that some predictive
mechanisms exist in widely-spread biological swarms, flocks, and networks. From
the industrial engineering point of view, inclusion of an efficient predictive
mechanism allows for a significant increase in the speed of consensus
convergence and also a reduction of the communication energy required to
achieve a predefined consensus performance.

how DAM can be modified to agree with the latter data set. The modification
follows the pattern suggested to reconcile any PQ-like approach with gravity.
Modified DAM allows precise predictions which can be testable against future
CMB and/or deep sample data.

709.0175 | Pairings on Jacobians of Hyperelliptic Curves | Consider the jacobian of a hyperelliptic genus two curve defined over a
finite field. Under certain restrictions on the endomorphism ring of the
jacobian we give an explicit description all non-degenerate, bilinear,
anti-symmetric and Galois-invariant pairings on the jacobian. From this
description it follows that no such pairing can be computed more efficiently
than the Weil pairing.
To establish this result, we need an explicit description of the
representation of the Frobenius endomorphism on the l-torsion subgroup of the
jacobian. This description is given. In particular, we show that if the
characteristic polynomial of the Frobenius endomorphism splits into linear
factors modulo l, then the Frobenius is diagonalizable.
Finally, under the restriction that the Frobenius element is an element of a
certain subring of the endomorphism ring, we prove that if the characteristic
polynomial of the Frobenius endomorphism splits into linear factors modulo l,
then the embedding degree and the total embedding degree of the jacobian with
respect to l are the same number.

a much-more-than-boring star formation history in recent years by the UV
satellite GALEX. The most massive bulges, brightest cluster galaxies, appear to
be relatively free of young stars. But smaller bulges, normal ellipticals and
lenticulars, often show unambiguous sign of recent star formation in their UV
flux. The fraction of such UV-bright bulges in the volume-limited sample climbs
up to the staggering 30%. The bulges of spirals follow similar trends but a
larger fraction showing signs of current and recent star formation. The
implication on the bulge formation and evolution is discussed.

709.0179 | The intrinsic degree of freedom for quasiparticle in thermodynamics with
medium effects | The thermodynamics with medium effects expressed by the temperature- and
density-dependent effective mass of quasiparticle is studied. Series
difficulties and many wrangles in references due to the extraordinary parameter
dependence are addressed. A new independent intrinsic degree of freedom of

709.018 | Harmonic oscillator chains as Wigner Quantum Systems: periodic and fixed
wall boundary conditions in gl(1|n) solutions | We describe a quantum system consisting of a one-dimensional linear chain of
n identical harmonic oscillators coupled by a nearest neighbor interaction. Two
boundary conditions are taken into account: periodic boundary conditions (where
the nth oscillator is coupled back to the first oscillator) and fixed wall
boundary conditions (where the first oscillator and the $n$th oscillator are
coupled to a fixed wall). The two systems are characterized by their
Hamiltonian. For their quantization, we treat these systems as Wigner Quantum
Systems (WQS), allowing more solutions than just the canonical quantization
solution. In this WQS approach, one is led to certain algebraic relations for
operators (which are linear combinations of position and momentum operators)
that should satisfy triple relations involving commutators and
anti-commutators. These triple relations have a solution in terms of the Lie
superalgebra gl(1|n). We study a particular class of gl(1|n) representations
V(p), the so-called ladder representations. For these representations, we
determine the spectrum of the Hamiltonian and of the position operators (for
both types of boundary conditions). Furthermore, we compute the eigenvectors of
the position operators in terms of stationary states. This leads to explicit
expressions for position probabilities of the n oscillators in the chain. An
analysis of the plots of such position probability distributions gives rise to
some interesting observations. In particular, the physical behavior of the
system as a WQS is very much in agreement with what one would expect from the
classical case, except that all physical quantities (energy, position and
momentum of each oscillator) have a finite spectrum.

709.0181 | The Nature of the Ultraluminous Oxygen-Rich Supernova Remnant in NGC
4449 | Optical images and spectra, both ground based and taken by Hubble Space
Telescope (HST), of the young, luminous O-rich supernova remnant in the
irregular galaxy NGC 4449 are presented. HST images of the remnant and its
local region were obtained with the ACS/WFC using filters F435W, F555W, F814W
(B, V, and I, respectively), F502N ([O III]), F658N (Halpha + [N II]), F660N
([N II]), and F550M (line-free continuum). These images show an unresolved
remnant (FWHM < 0.05 arcsec) located within a rich cluster of OB stars which
itself is enclosed by a nearly complete interstellar shell seen best in Halpha
+ [N II] emission approximately 8'' x 6'' (150 pc x 110 pc) in size. The
remnant and its associated OB cluster are isolated from two large nearby H II
regions. The ACS [O III] image shows the remnant may be partially surrounded by
a clumpy ring of emission approximately 1'' (~20 pc) in diameter. Recent
ground-based spectra of the remnant reveal (1) the emergence of broad,
blueshifted emission lines of [S II] 6716, 6731, [Ar III] 7136, and [Ca II]
7291, 7324 which were not observed in spectra taken in 1978 -- 1980; (2) faint
emission at 6540 -- 6605 A centered about Halpha and [N II] 6548, 6583 with an
expansion velocity of 500 +/- 100 km/s; and (3) excess emission around 4600 --
4700 A suggestive of a Wolf-Rayet population in the remnant's star cluster. We
use these new data to re-interpret the origin of the remnant's prolonged and
bright luminosity and propose that the remnant is strongly interacting with
dense, circumstellar wind loss material from a ~20 Msolar progenitor star.

709.0182 | Bell-state preparation for electron spins in a semiconductor double
quantum dot | A robust scheme for state preparation and state trapping for the spins of two
electrons in a semiconductor double quantum dot is presented. The system is
modeled by two spins coupled to two independent bosonic reservoirs. Decoherence
effects due to this environment are minimized by application of optimized
control fields which make the target state to the ground state of the isolated
driven spin system. We show that stable spin entanglement with respect to pure
dephasing is possible. Specifically, we demonstrate state trapping in a
maximally entangled state (Bell state) in the presence of decoherence.

709.0183 | The Formation of Slow-Massive-Wide Jets | I propose a model for the formation of slow-massive-wide (SMW) jets by
accretion disks around compact objects. This study is motivated by claims for
the existence of SMW jets in some astrophysical objects such as in planetary
nebulae (PNs) and in some active galactic nuclei in galaxies and in cooling
flow clusters. In this model the energy still comes from accretion onto a
compact object. The accretion disk launches two opposite jets with velocity of
the order of the escape velocity from the accreting object and with mass
outflow rate of ~1-20% of the accretion rate as in most popular models for jet
launching; in the present model these are termed fast-first-stage (FFS) jets.
However, the FFS jets encounter surrounding gas that originates in the mass
accretion process, and are terminated by strong shocks close to their origin.
Two hot bubbles are formed. These bubbles accelerate the surrounding gas to
form two SMW jets that are more massive and slower than the FFS jets. There are
two conditions for this mechanism to work. Firstly, the surrounding gas should
be massive enough to block the free expansion of the FFS jets. Most efficiently
this condition is achieved when the surrounding gas is replenished. Secondly,
the radiative energy losses must be small.

709.0187 | X-rays profiles in symmetric and asymmetric supernova remnants | The non-thermal X-rays from the SN 1006 NE rim present characteristic scale
lengths that are interpreted in the context of diffusion of a relativistic
electron. The adopted theoretical framework is the mathematical diffusion in
3D, 1D and 1D with drift as well as the Monte Carlo random walk in 1D with
drift. The asymmetric random walk with diffusion from a plane can explain the
scale widths of 0.04 pc upstream and 0.2 pc downstream in the non thermal
intensity of X-ray emission in SN 1006. A mathematical image of the non thermal
X-flux from an supernova remnant as well as profiles function of the distance
from the center can be simulated. This model provides a reasonable description

709.019 | A complex environment around Cir X-1 | We present the results of an archival 54 ks long Chandra observation of the
peculiar source Cir X--1 during the phase passage 0.223-0.261. A comparative
analysis of X-ray spectra, selected at different flux levels of the source,
allows us to distinguish between a very hard state, at a low countrate, and a
brighter, softer, highly absorbed spectrum during episodes of flaring activity,
when the unabsorbed source luminosity is about three times the value in the
hard state. The spectrum of the hard state clearly shows emission lines of
highly ionized elements, while, during the flaring state, the spectrum also
shows strong resonant absorption lines. The most intense and interesting
feature in this latter state is present in the Fe K alpha region: a very
broadened absorption line at energies ~ 6.5 keV that could result from a
smeared blending of resonant absorption lines of moderately ionized iron ions

and Fe XXVI, together with a smeared absorption edge above 7 keV. We argue that
the emitting region during the quiescent/hard state is constituted of a purely
photo-ionized medium, possibly present above an accretion disk, or of a
photo-ionized plasma present in a beamed outflow. During the flaring states the
source undergoes enhanced turbulent accretion that modifies both the accretion
geometry and the optical depth of the gas surrounding the primary X-ray source.

709.0191 | Including heavy flavour production in PDF fits | AT HERA heavy quarks may contribute up to 30% of the structure function
$F_2$. The introduction of heavy quarks requires an extension of the DGLAP
formalism. The effect of using different heavy flavour number schemes, and
different approaches to the running of $\alpha_s$, are compared using the ZEUS
PDF fit formalism. The potential of including charm data in the fit is
explored, using $D^*$ double differential cross-sections rather than the
inclusive quantity $F_2^{c\bar{c}}$.

709.0192 | The Atomic hypothesis: Physical consequences | The hypothesis that matter is made of some ultimate and indivisible objects,
together the restricted relativity principle, establishes a constraint on the
kind of variables we are allowed to use for the variational description of
elementary particles. We consider that the atomic hypothesis not only states
the indivisibility of elementary particles, but also that these ultimate
objects, if not annihilated, cannot be modified by any interaction so that all
allowed states of an elementary particle are only kinematical modifications of
any one of them. Terefore, an elementary particle cannot have excited states.
In this way, the kinematical group of spacetime symmetries not only defines the
symmetries of the system, but also the variables in terms of which the
mathematical description of the elementary particles can be expressed in either
the classical or the quantum mechanical description. When considering the

709.0198 | The host galaxy of GRB031203: a new spectroscopic study | The host galaxy of the long-duration gamma-ray burst (GRB) 031203 (HG031203)
offers a precious opportunity to study in detail the environment of a nearby
GRB. The aim is to better characterize this galaxy and analyse the possible
evolution with time of the spectroscopic quantities we derive. We analyse
HG031203 using a set of optical spectra acquired with the ESO-VLT and Keck
telescope. We compare the metallicity, luminosity and star formation properties
of this galaxy and of the other supernova-long gamma-ray burst hosts in the
local universe (z<0.2) against the KPNO International Spectroscopic Survey.
HG031203 is a metal poor, actively star forming galaxy (star formation rate of
12.9+/-2.2 {M_{sun} yr^-1) at z=0.1054. From the emission-line analysis we
derive an intrinsic reddening E_{HG}(B-V)\approx 0.4. This parameter doesn't
show a compelling evidence of evolution at a month time-scale. We find an
interstellar medium temperature of 12500 K and an electronic density of
N_{e}=160 cm^-3. After investigating for possible Wolf-Rayet emission features
in our spectra, we consider dubious the classification of HG031203 as a
Wolf-Rayet galaxy. Long gamma-ray burst (LGRB) and supernova hosts in the local
universe (z<0.2) show, on average, specific star formation rates higher than
ordinary star forming galaxy at the same redshift. On the other hand, we find
that half of the hosts follows the metallicity-luminosity relation found for
star-burst galaxies; HG031203 is a clear outlier, with its really low
metallicity (12+\log{{O/H}}=8.12+/-0.04).

spectroscopic survey hg031203 is a metal poor actively star forming galaxy star formation rate of 12922 m_sun yr1 at z01054 from the emissionline analysis we derive an intrinsic reddening e_hgbvapprox 04 this parameter doesnt show a compelling evidence of evolution at a month timescale we find an interstellar medium temperature of 12500 k and an electronic density of n_e160 cm3 after investigating for possible wolfrayet emission features in our spectra we consider dubious the classification of hg031203 as a wolfrayet galaxy long gammaray burst lgrb and supernova hosts in the local universe z02 show on average specific star formation rates higher than ordinary star forming galaxy at the same redshift on the other hand we find that half of the hosts follows the metallicityluminosity relation found for starburst galaxies hg031203 is a clear outlier with its really low metallicity 12logoh812004 | [['the', 'host', 'galaxy', 'of', 'the', 'longduration', 'gammaray', 'burst', 'grb', '031203',

709.0199 | No de Sitter invariant vacuum in massive gravity theory with ghost | In this letter we point out that the massive gravity theory with a graviton
ghost mode in de Sitter background cannot possess a de Sitter invariant vacuum
state. In order to avoid a negative norm state, we must associate the creation
operator of the ghost mode with a negative-energy mode function instead of a
positive-energy one as the mode function. Namely, we have to adopt a different
procedure of quantization for a ghost. When a theory has a symmetry mixing a
ghost mode with ordinary non-ghost modes, the choice of a ghost mode is not
unique. However, quantization of a ghost is impossible without specifying a
choice of ghost mode, which breaks the symmetry. For this reason, the vacuum
state cannot respect the symmetry. In the massive gravity theory with a
graviton ghost mode in de Sitter background, the ghost is the helicity-0 mode
of the graviton. This ghost mode is mixed with the other helicity graviton
modes under the action of de Sitter symmetry. Therefore, there is no de Sitter
invariant vacuum in such models. This leads to an interesting possibility that
non-covariant cutoff of the low energy effective theory may naturally arise. As
a result, the instability due to the pair production of a ghost and normal
non-ghost particles gets much milder and that the model may escape from being
rejected.

709.02 | Confinement encoded in Landau gauge gluon and ghost propagators | An introduction is given into current lattice investigations of the
non-perturbative gluon and ghost propagators, in the light of the
Gribov-Zwanziger and Kugo-Ojima scenarios of confinement, in the context of

709.0202 | Can very massive stars avoid Pair-instability Supernovae? | Very massive primordial stars ($140 M_{\odot} < M < 260 M_{\odot}$) are
supposed to end their lives as pair-instability supernovae. Such an event can
be traced by a typical chemical signature in low metallicity stars, but at the
present time, this signature is lacking in the extremely metal-poor stars we
are able to observe. Does it mean that those very massive objects did not form,
contrarily to the primordial star formation scenarios? Could they avoid this
tragical fate?
We explore the effects of rotation, anisotropic mass loss and magnetic fields
on the core size of a very massive Population III model, in order to check if
its mass is sufficiently modified to prevent the pair instability.
We obtain that a Population III model of $150 M_{\odot}$ with
$\upsilon/\upsilon_{\rm crit}=0.56$ computed with the inclusion of wind
anisotropy and Tayler-Spruit dynamo avoids the pair instability explosion.

709.0203 | Enhancement of polarization in a spin-orbit coupling quantum wire with a
constriction | We investigate the enhancement of spin polarization in a quantum wire in the
presence of a constriction and a spin-orbit coupling segment. It is shown that
the spin-filtering effect is significantly heightened in comparison with the
configuration without the constriction. It is understood in the studies that
the constriction structure plays a critical role in enhancing the spin
filtering by means of confining the incident electrons to occupy one channel
only while the outgoing electrons occupy two channels. The enhancement of
spin-filtering has also been analyzed within the perturbation theory. Because
the spin polarization arises mainly from the scattering between the
constriction and the segment with spin-orbit coupling, the sub-band mixing

709.0204 | Capacity constraints and the inevitability of mediators in adword
auctions | One natural constraint in the sponsored search advertising framework arises
from the fact that there is a limit on the number of available slots,
especially for the popular keywords, and as a result, a significant pool of
advertisers are left out. We study the emergence of diversification in the
adword market triggered by such capacity constraints in the sense that new
market mechanisms, as well as, new for-profit agents are likely to emerge to
combat or to make profit from the opportunities created by shortages in
ad-space inventory. We propose a model where the additional capacity is
provided by for-profit agents (or, mediators), who compete for slots in the
original auction, draw traffic, and run their own sub-auctions. The quality of
the additional capacity provided by a mediator is measured by its {\it fitness}
factor. We compute revenues and payoffs for all the different parties at a {\it
symmetric Nash equilibrium} (SNE) when the mediator-based model is operated by
a mechanism currently being used by Google and Yahoo!, and then compare these
numbers with those obtained at a corresponding SNE for the same mechanism, but
without any mediators involved in the auctions. Such calculations allow us to
determine the value of the additional capacity. Our results show that the
revenue of the auctioneer, as well as the social value (i.e. efficiency),
always increase when mediators are involved; moreover even the payoffs of {\em
all} the bidders will increase if the mediator has a high enough fitness. Thus,
our analysis indicates that there are significant opportunities for
diversification in the internet economy and we should expect it to continue to
develop richer structure, with room for different types of agents and
mechanisms to coexist.

709.0206 | Establishing the Uniqueness of the Connection between SdS_5 and
Conformally Invariant Relativistic Systems: A Group/Field Theoretical
Approach | Adopting as working assumption that the conformal group O(4,2) of Minkowski
space, being the largest symmetry group which respects its light cone
structure, is the appropriate global symmetry underlying the description of
relativistic systems, it is shown that AdS$_5$ uniquely emerges as the space on
the boundary of which a corresponding relativistic field system should be
accommodated. The basic mathematical tools employed for establishing this
result are (a) Cartan's theory of spinors and (b) group contraction methods.
Extending our considerations to supersymmetry it is demostrated how an $N$=1
SUSY YM field system can emerge as a broken version of an $N$=4 SUSY YM field
system. An especially important feature of the presentation is the `unearthing'
of seminal, independent from each other, works of I. Segal and of S. Fubini
which give a purely field theoretical perspective on the intimate relation
between conformally invariant relativistic field theories and AdS$_5$
including, in particular, the warping phenomenon.

709.0207 | Modular intersection cohomology complexes on flag varieties | We present a combinatorial procedure (based on the W-graph of the Coxeter
group) which shows that the characters of many intersection cohomology
complexes on low rank complex flag varieties with coefficients in an arbitrary
field are given by Kazhdan-Lusztig basis elements. Our procedure exploits the
existence and uniqueness of parity sheaves. In particular we are able to show
that the characters of all intersection cohomology complexes with coefficients
in a field on the flag variety of type A_n for n < 7 are given by
Kazhdan-Lusztig basis elements. By results of Soergel, this implies a part of
Lusztig's conjecture for SL(n) with n \le 7. We also give examples where our
techniques fail.
In the appendix by Tom Braden examples are given of intersection cohomology

709.0208 | Three regularization models of the Navier-Stokes equations | We determine how the differences in the treatment of the subfilter-scale
physics affect the properties of the flow for three closely related
regularizations of Navier-Stokes. The consequences on the applicability of the
regularizations as SGS models are also shown by examining their effects on
superfilter-scale properties. Numerical solutions of the Clark-alpha model are
compared to two previously employed regularizations, LANS-alpha and Leray-alpha
(at Re ~ 3300, Taylor Re ~ 790) and to a DNS. We derive the Karman-Howarth
equation for both the Clark-alpha and Leray-alpha models. We confirm one of two
possible scalings resulting from this equation for Clark as well as its
associated k^(-1) energy spectrum. At sub-filter scales, Clark-alpha possesses
similar total dissipation and characteristic time to reach a statistical
turbulent steady-state as Navier-Stokes, but exhibits greater intermittency. As
a SGS model, Clark reproduces the energy spectrum and intermittency properties
of the DNS. For the Leray model, increasing the filter width decreases the
nonlinearity and the effective Re is substantially decreased. Even for the
smallest value of alpha studied, Leray-alpha was inadequate as a SGS model. The
LANS energy spectrum k^1, consistent with its so-called "rigid bodies,"
precludes a reproduction of the large-scale energy spectrum of the DNS at high
Re while achieving a large reduction in resolution. However, that this same
feature reduces its intermittency compared to Clark-alpha (which shares a
similar Karman-Howarth equation). Clark is found to be the best approximation
for reproducing the total dissipation rate and the energy spectrum at scales
larger than alpha, whereas high-order intermittency properties for larger
values of alpha are best reproduced by LANS-alpha.

709.0209 | Resolving the complex structure of the dust torus in the active nucleus
of the Circinus galaxy | To test the dust torus model for active galactic nuclei directly, we study
the extent and morphology of the nuclear dust distribution in the Circinus
galaxy using high resolution interferometric observations in the mid-infrared
with the MIDI instrument at the Very Large Telescope Interferometer. We find
that the dust distribution in the nucleus of Circinus can be explained by two
components, a dense and warm disk-like component of 0.4 pc size and a slightly
cooler, geometrically thick torus component with a size of 2.0 pc. The disk
component is oriented perpendicular to the ionisation cone and outflow and
seems to show the silicate feature at 10 micron in emission. It coincides with
a nuclear maser disk in orientation and size. From the energy needed to heat
the dust, we infer a luminosity of the accretion disk corresponding to 20% of
the Eddington luminosity of the nuclear black hole. We find that the
interferometric data are inconsistent with a simple, smooth and axisymmetric
dust emission. The irregular behaviour of the visibilities and the shallow
decrease of the dust temperature with radius provide strong evidence for a
clumpy or filamentary dust structure. We see no evidence for dust reprocessing,
as the silicate absorption profile is consistent with that of standard galactic
dust. We argue that the collimation of the ionising radiation must originate in
the geometrically thick torus component. Our findings confirm the presence of a
geometrically thick, torus-like dust distribution in the nucleus of Circinus,
as required in unified schemes of Seyfert galaxies. Several aspects of our data
require that this torus is irregular, or "clumpy".

709.021 | $\eta'$ production in proton-proton collisions far from the threshold | I discuss exclusive production of the $\eta'$ meson in the $pp \to p\eta'p$
reaction far from the threshold. The contribution of diffractive component as
well as that for $\gamma^* \gamma^* \to \eta'$ fusion are calculated. In the
first case the formalism of unintegrated gluon distribution functions (UGDF) is
used. The distributions in the Feynman $x_F$ (or rapidity), transferred
four-momenta squared between initial and final protons ($t_1$, $t_2$) and
azimuthal angle difference between outgoing protons ($\Phi$) are calculated.
The deviations from the $\sin^2(\Phi)$ dependence predicted by one-step
vector-vector-pseudoscalar coupling are quantified and discussed. The results
are compared with the results of the WA102 collaboration at CERN. Most of the
models of UGDF from the literature give too small cross section as compared to
the WA102 data and predict angular distribution in relative azimuthal angle
strongly asymmetric with respect to $\pi/2$ in disagreement with the WA102
data. This points to a different mechanism at the WA102 energy. Predictions for
RHIC, Tevatron and LHC are given.

709.0212 | Non-critically squeezed light via spontaneous rotational symmetry
breaking | We theoretically address squeezed light generation through the spontaneous
breaking of the rotational invariance occuring in a type I degenerate optical
parametric oscillator (DOPO) pumped above threshold. We show that a DOPO with
spherical mirrors, in which the signal and idler fields correspond to first
order Laguerre-Gauss modes, produces a perfectly squeezed vacuum with the shape
of a Hermite-Gauss mode, within the linearized theory. This occurs at any
pumping level above threshold, hence the phenomenon is non-critical.

709.0215 | Energetic radiation and the sulfur chemistry of protostellar envelopes:
Submillimeter interferometry of AFGL 2591 | CONTEXT: The chemistry in the inner few thousand AU of accreting envelopes
around young stellar objects is predicted to vary greatly with far-UV and X-ray
irradiation by the central star. Aim We search for molecular tracers of
high-energy irradiation by the protostar in the hot inner envelope. METHODS:
The Submillimeter Array (SMA) has observed the high-mass star forming region
AFGL 2591 in lines of CS, SO, HCN, HCN(v2=1), and HC15N with 0.6" resolution at
350 GHz probing radial scales of 600-3500 AU for an assumed distance of 1 kpc.
The SMA observations are compared with the predictions of a chemical model
fitted to previous single-dish observations. RESULTS: The CS and SO main peaks
are extended in space at the FWHM level, as predicted in the model assuming
protostellar X-rays. However, the main peak sizes are found smaller than
modeled by nearly a factor of 2. On the other hand, the lines of CS, HCN, and
HC15N, but not SO and HCN(v2=1), show pedestal emissions at radii of about 3500
AU that are not predicted. All lines except SO show a secondary peak within the
approaching outflow cone. A dip or null in the visibilities caused by a sharp
decrease in abundance with increasing radius is not observed in CS and only
tentatively in SO. CONCLUSIONS: The emission of protostellar X-rays is
supported by the good fit of the modeled SO and CS amplitude visibilities
including an extended main peak in CS. The broad pedestals can be interpreted
by far-UV irradiation in a spherically non-symmetric geometry, possibly
comprising outflow walls on scales of 3500 -- 7000 AU. The extended CS and SO
main peaks suggest sulfur evaporation near the 100 K temperature radius.

709.0217 | Mobility promotes and jeopardizes biodiversity in rock-paper-scissors
games | Biodiversity is essential to the viability of ecological systems. Species
diversity in ecosystems is promoted by cyclic, non-hierarchical interactions
among competing populations. Such non-transitive relations lead to an evolution
with central features represented by the `rock-paper-scissors' game, where rock
crushes scissors, scissors cut paper, and paper wraps rock. In combination with
spatial dispersal of static populations, this type of competition results in
the stable coexistence of all species and the long-term maintenance of
biodiversity. However, population mobility is a central feature of real
ecosystems: animals migrate, bacteria run and tumble. Here, we observe a
critical influence of mobility on species diversity. When mobility exceeds a
certain value, biodiversity is jeopardized and lost. In contrast, below this
critical threshold all subpopulations coexist and an entanglement of travelling
spiral waves forms in the course of temporal evolution. We establish that this
phenomenon is robust, it does not depend on the details of cyclic competition
or spatial environment. These findings have important implications for
maintenance and evolution of ecological systems and are relevant for the
formation and propagation of patterns in excitable media, such as chemical
kinetics or epidemic outbreaks.

709.0218 | Inferring Neuronal Network Connectivity using Time-constrained Episodes | Discovering frequent episodes in event sequences is an interesting data
mining task. In this paper, we argue that this framework is very effective for
analyzing multi-neuronal spike train data. Analyzing spike train data is an
important problem in neuroscience though there are no data mining approaches
reported for this. Motivated by this application, we introduce different
temporal constraints on the occurrences of episodes. We present algorithms for
discovering frequent episodes under temporal constraints. Through simulations,
we show that our method is very effective for analyzing spike train data for
unearthing underlying connectivity patterns.

709.022 | The influence of out-of-plane disorder on the formation of pseudogap and
Fermi arc in Bi2Sr2-xRxCuOy (R=La and Eu) | We found that the length of the Fermi arc decreases with increasing
out-of-plane disorder by performing angle resolved photoemission spectroscopy
(ARPES) measurements in the superconducting state of optimally doped R=La and
Eu samples of Bi2Sr2−xRxCuOy. Since out-of-plane disorder stabilizes the
antinodal pseudogap as was shown in our previous study of the normal state, the
present results indicate that this antinodal pseudogap persists into the
superconducting state and decreases the Fermi arc length. We think that the
shrinkage of the Fermi arc reduces the superfluid density, which explains the

Soft Supersymmetry Breaking | We scan the landscape of flux compactifications for the Calabi-Yau manifold
$\mathbb{P}^4_{[1,1,1,6,9]}$ with two K\" ahler moduli by varying the value of
the flux superpotential $W_0$ over a large range of values. We do not include
uplift terms. We find a rich phase structure of AdS and dS vacua. Starting with
$W_0\sim 1$ we reproduce the exponentially large volume scenario, but as $W_0$
is reduced new classes of minima appear. One of them corresponds to the
supersymmetric KKLT vacuum while the other is a new, deeper non-supersymmetric
minimum. We study how the bare cosmological constant and the soft supersymmetry
breaking parameters for matter on D7 branes depend on $W_0$, for these classes
of minima. We discuss potential applications of our results.

709.0222 | Large-eddy simulation of the flow in a lid-driven cubical cavity | Large-eddy simulations of the turbulent flow in a lid-driven cubical cavity
have been carried out at a Reynolds number of 12000 using spectral element
methods. Two distinct subgrid-scales models, namely a dynamic Smagorinsky model
and a dynamic mixed model, have been both implemented and used to perform
long-lasting simulations required by the relevant time scales of the flow. All
filtering levels make use of explicit filters applied in the physical space (on
an element-by-element approach) and spectral (modal) spaces. The two
subgrid-scales models are validated and compared to available experimental and
numerical reference results, showing very good agreement. Specific features of
lid-driven cavity flow in the turbulent regime, such as inhomogeneity of
turbulence, turbulence production near the downstream corner eddy, small-scales
localization and helical properties are investigated and discussed in the
large-eddy simulation framework. Time histories of quantities such as the total
energy, total turbulent kinetic energy or helicity exhibit different evolutions

709.0223 | Brief encounter networks | Many complex human and natural phenomena can usefully be represented as
networks describing the relationships between individuals. While these
relationships are typically intermittent, previous research has used network
representations that aggregate the relationships at discrete intervals.
However, such an aggregation discards important temporal information, thus
inhibiting our understanding of the networks dynamic behaviour and evolution.
We have recorded patterns of human urban encounter using Bluetooth technology
thus retaining the temporal properties of this network. Here we show how this
temporal information influences the structural properties of the network. We
show that the temporal properties of human urban encounter are scale-free,
leading to an overwhelming proportion of brief encounters between individuals.
While previous research has shown preferential attachment to result in
scale-free connectivity in aggregated network data, we found that scale-free
connectivity results from the temporal properties of the network. In addition,
we show that brief encounters act as weak social ties in the diffusion of
non-expiring information, yet persistent encounters provide the means for
sustaining time-expiring information through a network.

\to p \eta' p$ and $p p \to p J/\psi p$. In the first case I consider
diffractive pQCD approach and $\gamma \gamma$ fusion, in the second case the
amplitude is linked to the amplitude of the process for $J/\psi$

709.0225 | Anomalous finite-size effects in the Battle of the Sexes | The Battle of the Sexes describes asymmetric conflicts in mating behavior of
males and females. Males can be philanderer or faithful, while females are
either fast or coy, leading to a cyclic dynamics. The adjusted replicator
equation predicts stable coexistence of all four strategies. In this situation,
we consider the effects of fluctuations stemming from a finite population size.
We show that they unavoidably lead to extinction of two strategies in the
population. However, the typical time until extinction occurs strongly prolongs
with increasing system size. In the meantime, a quasi-stationary probability
distribution forms that is anomalously flat in the vicinity of the coexistence
state. This behavior originates in a vanishing linear deterministic drift near
the fixed point. We provide numerical data as well as an analytical approach to
the mean extinction time and the quasi-stationary probability distribution.

709.0227 | Importance of constraining the dense matter Equation of State in pulsar
astrophysics | We study the dependence of the surface magnetic fields of radio pulsars on
the choice of Equations of State, pulsar masses and the values of the angle
between the magnetic axis and the spin axis of the pulsars within simple dipole
model. We show that the values of the surface magnetic field can be even order
of magnitude different from its canonical values. This difference will effect
any magnetosphere related model to explain observational features of radio
pulsars and magnetars. We find a significant difference of the value of the
surface magnetic field from the commonly quoted value for the faster member of
the double pulsar system, i.e. PSR J0737-3039A as here both the mass of the
pulsar and the angle between the magnetic axis and the spin axis are known. Our
study reveals the importance of constraining the dense matter Equations of

709.0233 | Parameterization of the Angular Distribution of Gamma Rays Produced by
p-p Interaction in Astronomical Environment | We present the angular distribution of gamma rays produced by proton-proton
interactions in parameterized formulae to facilitate calculations in
astrophysical environments. The parameterization is derived from Monte Carlo
simulations of the up-to-date proton-proton interaction model by Kamae et al.
(2005) and its extension by Kamae et al. (2006). This model includes the
logarithmically rising inelastic cross section, the diffraction dissociation
process and Feynman scaling violation. The extension adds two baryon resonance
contributions: one representing the Delta(1232) and the other representing
multiple resonances around 1600 MeV/c^2. We demonstrate the use of the formulae
by calculating the predicted gamma-ray spectrum for two different cases: the
first is a pencil beam of protons following a power law and the second is a
fanned proton jet with a Gaussian intensity profile impinging on the

| astro-ph | we present the angular distribution of gamma rays produced by protonproton interactions in parameterized formulae to facilitate calculations in astrophysical environments the parameterization is derived from monte carlo simulations of the uptodate protonproton interaction model by kamae et al 2005 and its extension by kamae et al 2006 this model includes the logarithmically rising inelastic cross section the diffraction dissociation process and feynman scaling violation the extension adds two baryon resonance contributions one representing the delta1232 and the other representing multiple resonances around 1600 mevc2 we demonstrate the use of the formulae by calculating the predicted gammaray spectrum for two different cases the first is a pencil beam of protons following a power law and the second is a fanned proton jet with a gaussian intensity profile impinging on the surrounding material in both cases we find that the predicted gammaray spectrum to be dependent on the viewing angle | [['we', 'present', 'the', 'angular', 'distribution', 'of', 'gamma', 'rays', 'produced', 'by', 'protonproton', 'interactions', 'in', 'parameterized', 'formulae', 'to', 'facilitate', 'calculations', 'in', 'astrophysical', 'environments', 'the', 'parameterization', 'is', 'derived', 'from', 'monte', 'carlo', 'simulations', 'of', 'the', 'uptodate', 'protonproton', 'interaction', 'model', 'by', 'kamae', 'et', 'al', '2005', 'and', 'its', 'extension', 'by', 'kamae', 'et', 'al', '2006', 'this', 'model', 'includes', 'the', 'logarithmically', 'rising', 'inelastic', 'cross', 'section', 'the', 'diffraction', 'dissociation', 'process', 'and', 'feynman', 'scaling', 'violation', 'the', 'extension', 'adds', 'two', 'baryon', 'resonance', 'contributions', 'one', 'representing', 'the', 'delta1232', 'and', 'the', 'other', 'representing', 'multiple', 'resonances', 'around', '1600', 'mevc2', 'we', 'demonstrate', 'the', 'use', 'of', 'the', 'formulae', 'by', 'calculating', 'the', 'predicted', 'gammaray', 'spectrum', 'for', 'two', 'different', 'cases', 'the', 'first', 'is', 'a', 'pencil', 'beam', 'of', 'protons', 'following', 'a', 'power', 'law', 'and', 'the', 'second', 'is', 'a', 'fanned', 'proton', 'jet', 'with', 'a', 'gaussian', 'intensity', 'profile', 'impinging', 'on', 'the', 'surrounding', 'material', 'in', 'both', 'cases', 'we', 'find', 'that', 'the', 'predicted', 'gammaray', 'spectrum', 'to', 'be', 'dependent', 'on', 'the', 'viewing', 'angle']] | [-0.08087017109630092, 0.15953907370147366, -0.08222314223042383, 0.10578167606377828, -0.0632468858333742, -0.07760578390303062, 0.03193727781021055, 0.35495834713864244, -0.2201374813190805, -0.34739407315700244, -0.037362060719794726, -0.3489219672421631, -0.0519085534967032, 0.1940691192562523, 0.04817527873541585, 0.04726541038538523, 0.058542193796473165, -0.05642235374090655, -0.020090482300053655, -0.17748316822436033, 0.30032144565035235, 0.13382216261687294, 0.23456306194405277, 0.07287128676579102, 0.07709448512068531, 0.06268000390830657, -0.07597381410957783, -0.04977147644462362, -0.1478678370076767, 0.07664149297376308, 0.1964576742326647, 0.08419133794037688, 0.14542476582847186, -0.36723968479001035, -0.19880725301789656, 0.07556354107910254, 0.12762388004140066, 0.07055524390522115, -0.043497681180202724, -0.2831639246327565, 0.009964245499655505, -0.22226322611212582, -0.1494485748550486, -0.012021073146454439, 0.023352105458010763, 0.024092345082844864, -0.27992890473930226, 0.0880146020782749, 0.009493743130802833, 0.04540303220925345, -0.05379853531133834, -0.13396477826477196, -0.02199651041199397, 0.023217230660593974, 0.05034902530480895, 0.03801368292883638, 0.15461994558510264, -0.11658612537922826, -0.12516398161912223, 0.3701271725843517, -0.033732729843636386, -0.1306627377142642, 0.12431188925144407, -0.1799147163749041, -0.12323188955033035, 0.18638592622174113, 0.1719816365457396, 0.11411048113115502, -0.16334351872862785, 0.10359182635215955, -0.045107299094744674, 0.1476172524279346, 0.10830143977256629, -0.048095375623697756, 0.16967821034646574, 0.13514086277530396, -0.04474474948943411, 0.12016929839792405, -0.1708028128670666, -0.0894622459805308, -0.3265023431182064, -0.07931255376835247, -0.1560470803809546, 0.05021309061366565, -0.07160360897670894, -0.10713867618133557, 0.3830245932776656, 0.09110427180917671, 0.2429706245135741, 0.020990529730478488, 0.32303565944351204, 0.12378356638329335, 0.014459864881777224, 0.081181993098592, 0.2878633386849257, 0.17893877947678002, 0.123623226346384, -0.21996824289910377, 0.05948279182982925, 0.0491131356895445] |
