710.4953 | Different canonical formulations of Einstein's theory of gravity | We describe the four most famous versions of the classical canonical
formalism in the Einstein theory of gravity: the Arnovitt-Deser-Misner
formalism, the Faddeev-Popov formalism, the tetrad formalism in the usual form,
and the tetrad formalism in the form best suited for constructing the loop
theory of gravity, which is now being developed. We present the canonical
transformations relating these formalisms. The paper is written mainly for
pedagogical purposes.

particles produced in interactions of cosmogenic neutrinos. We consider energy
loss of high energy staus due to photonuclear and weak interactions. We show
that there are optimal nadir angles for which the stau signal is a factor of
several hundred larager than muons. We discuss how one could potentially
eliminate the muon background by considering the energy loss of muons in the
detector. We also show results for the showers produced by weak interactions of

710.4956 | SMA High Angular Resolution Imaging of the Lensed Quasar APM08279+5255 | We present Submillimeter Array observations of the z=3.91 gravitationally
lensed broad absorption line quasar APM08279+5255 which spatially resolve the
1.0mm (0.2mm rest-frame) dust continuum emission. At 0.4" resolution, the
emission is separated into two components, a stronger, extended one to the
northeast (46+/-5mJy) and a weaker, compact one to the southwest (15+/-2mJy).
We have carried out simulations of the gravitational lensing effect responsible
for the two submm components in order to constrain the intrinsic size of the
submm continuum emission. Using an elliptical lens potential, the best fit
lensing model yields an intrinsic (projected) diameter of ~80pc, which is not
as compact as the optical/near-infrared (NIR) emission and agrees with previous
size estimates of the gas and dust emission in APM08279+5255. Based on our

originates from a warm dust component (T_d=150-220K) that is mainly heated by
the AGN rather than by a starburst (SB). The flux is boosted by a factor of ~90

710.4957 | Fixing the fixed-point system - Applying Dynamic Renormalization Group
to systems with long-range interactions | In this paper a mode of using the Dynamic Renormalization Group (DRG) method
is suggested in order to cope with inconsistent results obtained when applying
it to a continuous family of one-dimensional nonlocal models. The key
observation is that the correct fixed-point dynamical system has to be
identified during the analysis in order to account for all the relevant terms
that are generated under renormalization. This is well established for static
problems, however poorly implemented in dynamical ones. An application of this
approach to a nonlocal extension of the Kardar-Parisi-Zhang equation resolves
certain problems in one-dimension. Namely, obviously problematic predictions
are eliminated and the existing exact analytic results are recovered.

710.4958 | Thermodynamics of Protein Folding from Coarse-Grained Models'
Perspectives | Folding and aggregation of proteins, the interaction between proteins and
membranes, as well as the adsorption of organic soft matter to inorganic solid
substrates belong to the most interesting challenges in understanding structure
and function of complex macromolecules. This is reasoned by the
interdisciplinary character of the associated questions ranging from the
molecular origin of the loss of biological functionality as, for example, in
Alzheimer's disease to the development of organic circuits for biosensory
applications. In this lecture, we focus on the analysis of mesoscopic models
for protein folding, aggregation, and hybrid systems of soft and solid
condensed matter. The simplicity of the coarse-grained models allows for a more
universal description of the notoriously difficult problem of protein folding.
In this approach, classifications of structure formation processes with respect
to the conformational pseudophases are possible. This is similar in aggregation
and adsorption processes, where the individual folding propensity is influenced
by external forces. The main problem in studies of conformational transitions
is that the sequences of amino acids proteins are built up of are necessarily
of finite length and, therefore, a thermodynamic limit does not exist. Thus,
structural transitions are not phase transitions in the strict thermodynamic
sense and the analysis of pseudouniversal aspects is intricate, as apparently
small-system effects accompany all conformational transitions and cannot be
neglected.

710.496 | Freezing and Collapse of Flexible Polymers on Regular Lattices in Three
Dimensions | We analyze the crystallization and collapse transition of a simple model for
flexible polymer chains on simple cubic and face-centered cubic lattices by
means of sophisticated chain-growth methods. In contrast to bond-fluctuation
polymer models in certain parameter ranges, where these two conformational
transitions were found to merge in the thermodynamic limit, we conclude from
our results that the two transitions remain well-separated in the limit of
infinite chain lengths. The reason for this qualitatively distinct behavior is
presumably due to the ultrashort attractive interaction range in the lattice
models considered here.

710.4961 | A Note on Graviton Amplitudes for New Twistor String Theories | A new class of twistor string theories were recently constructed by
Abou-Zeid, Hull and Mason. The most interesting one of these theories has the
particle content of N=8 supergravity. Arguments are given for the vanishing of

710.4962 | Connecting Galaxy Disk and Extended Halo Gas Kinematics | We have explored the galaxy disk/extended halo gas kinematic relationship
using rotation curves (Keck/ESI) of ten intermediate redshift galaxies which
were selected by MgII halo gas absorption observed in quasar spectra. Previous
results of six edge-on galaxies, probed along their major axis, suggest that
observed halo gas velocities are consistent with extended disk-like halo
rotation at galactocentric distances of 25-72 kpc. Using our new sample, we
demonstrate that the gas velocities are by and large not consistent with being
directly coupled to the galaxy kinematics. Thus, mechanisms other than
co-rotation dynamics (i.e., gas inflow, feedback, galaxy-galaxy interactions,
etc.) must be invoked to account for the overall observed kinematics of the
halo gas. In order to better understand the dynamic interaction of the
galaxy/halo/cosmic web environment, we performed similar mock observations of
galaxies and gaseous halos in Lambda-CDM cosmological simulations. We discuss
an example case of a z=0.92 galaxy with various orientations probing halo gas
at a range of positions. The gas dynamics inferred using simulated quasar
absorption lines are consistent with observational data.

both cases the effective energy density arising from linear perturbations is of
the order of 10^-5 the matter density, as would be expected, with an effective
equation of state w ~ -1/19. Employing a modified Halofit code to extend our
results to quasilinear scales, we find that, while larger, the deviations from
Robertson-Walker behaviour remain of the order of 10^-5.

710.4966 | Uncertainties of the antiproton flux from Dark Matter annihilation in
comparison to the EGRET excess of diffuse gamma rays | The EGRET excess of diffuse Galactic gamma rays shows all the features
expected from dark matter annihilation (DMA): a spectral shape given by the
fragmentation of mono-energetic quarks, which is the same in all sky directions
and an intensity distribution of the excess expected from a standard dark
matter halo, predicted by the rotation curve. From the EGRET excess one can
predict the flux of antiprotons from DMA. However, how many antiprotons arrive
at the detector strongly depends on the propagation model. The conventional
isotropic propagation models trap the antiprotons in the Galaxy leading to a
local antiproton flux far above the observed flux. According to Bergstrom et.
al. this excludes the DMA interpretation of the EGRET excess. Here it is shown
that more realistic anisotropic propagation models, in which most antiprotons

710.4969 | A Near-Infrared Spectroscopic Study of the Accreting Magnetic White
Dwarf SDSS J121209.31+013627.7 and its Substellar Companion | The nature of the excess near-infrared emission associated with the magnetic
white dwarf commonly known as SDSS 1212 is investigated primarily through
spectroscopy, and also via photometry. The inferred low mass secondary in this
system has been previously detected by the emission and variation of H$\alpha$,
and the $1-2.5$ $\mu$m spectral data presented here are consistent with the
presence of a late L or early T dwarf. The excess flux seen beyond 1.5 $\mu$m
in the phase-averaged spectrum is adequately modeled with an L8 dwarf
substellar companion and cyclotron emission in a 7 MG magnetic field. This
interesting system manifests several observational properties typical of

explosao para a determinacao da natureza de pontos fixos (pontos de equilibrio
degenerados. Aplicamos o metodo a dois modelos hamiltonianos com um e dois
graus de liberdade, respectivamente. Primeiramente, analisamos um sistema
formado por um pendulo simples submetido a um torque externo constante T. Em
seguida, consideramos um sistema formado por um pendulo duplo com segmentos de
comprimentos e massas iguais, tambem submetidos a torques externos constantes e
nao nulos. A presenca de pontos de equilibrio degenerados nos casos dos
pendulos simples e duplo ocorre para certos valores dos torques externos.
In this second article on Hamiltonian systems, we present the blow-up method
for the determination of the nature of degenerate fixed points (equilibrium
points). We apply the method to two hamiltonian models with one and two degrees
of freedom, respectively. Firstly we study a system formed by a simple pendulum
submitted to a constant external torque T. Then we consider a system formed by
a double pendulum of segments with equal lengths and masses, also submitted to
non-vanishing constant external torques. The presence of degenerate equilibrium
points in both cases of simple and double pendulums occurs for some values of
the external torques.

710.4971 | Limits of Gaudin algebras, quantization of bending flows, Jucys--Murphy
elements and Gelfand--Tsetlin bases | Gaudin algebras form a family of maximal commutative subalgebras in the
tensor product of $n$ copies of the universal enveloping algebra $U(\g)$ of a
semisimple Lie algebra $\g$. This family is parameterized by collections of
pairwise distinct complex numbers $z_1,...,z_n$. We obtain some new commutative
subalgebras in $U(\g)^{\otimes n}$ as limit cases of Gaudin subalgebras. These
commutative subalgebras turn to be related to the hamiltonians of bending flows

710.4972 | Nonlinear polarisation and dissipative correspondence between low
frequency fluid and gyrofluid equations | The correspondence between gyrofluid and low frequency fluid equations is
examined. The lowest order conservative effects in ExB advection, parallel
dynamics, and curvature match trivially. The principal concerns are
polarisation fluxes, and dissipative parallel viscosity and parallel heat
fluxes. The emergence of the polarisation heat flux in the fluid model and its
contribution to the energy theorem is reviewed. It is shown that gyroviscosity
and the polarisation fluxes are matched by the finite gyroradius corrections to
advection in the long wavelength limit, provided that the differences between
gyrocenter and particle representations is taken into account. The dissipative
parallel viscosity is matched by the residual thermal anisotropy in the
gyrofluid model in the collision dominated limit. The dissipative parallel heat
flux is matched by the gyrofluid parallel heat flux variables in the collision
dominated limit. Hence, the gyrofluid equations are a complete superset of the
low frequency fluid equations.

710.4973 | Liquid crystal anchoring transitions on aligning substrates processed by
plasma beam | We observe a sequence of the anchoring transitions in nematic liquid crystals
(NLC) sandwiched between the hydrophobic polyimide substrates treated with the
plasma beam. There is a pronounced continuous transition from homeotropic to
low tilted (nearly planar) alignment with the easy axis parallel to the
incidence plane of the plasma beam (the zenithal transition) that takes place
as the exposure dose increases. In NLC with positive dielectric anisotropy, a
further increase in the exposure dose results in in-plane reorientation of the
easy axis by 90 degrees (the azimuthal transition). This transition occurs
through the two-fold degenerated alignment characteristic for the second order
anchoring transitions. In contrast to critical behavior of anchoring, the
contact angle of NLC and water on the treated substrates monotonically declines
with the exposure dose. It follows that the surface concentration of
hydrophobic chains decreases continuously. The anchoring transitions under
consideration are qualitatively interpreted by using a simple phenomenological
model of competing easy axes which is studied by analyzing anchoring diagrams
of the generalized polar and non-polar anchoring models.

710.4974 | Measurement of CP Asymmetries and Branching Fractions in a
Time-Dependent Dalitz Analysis of B^0-->(rho pi)^0 and a Constraint on the
Quark Mixing Angle phi_2 | We present the results of a time-dependent Dalitz plot analysis of B0 --> pi+
pi- pi0 decays based on a 414/fb data sample that contains 449 x 10^6 BB pairs.
The data was collected on the Upsilon(4S) resonance with the Belle detector at
the KEKB asymmetric energy e+e- collider. Combining our analysis with
information on charged B decay modes, we perform a full Dalitz and isospin
analysis and obtain a constraint on the quark mixing angle phi_2, 68deg. <
phi_2 < 95deg. at the 68.3% confidence level for the phi_2 solution consistent
with the standard model (SM). A large SM-disfavored region also remains. The
branching fractions for the decay processes of B0 --> rho+-(770) pi-+ and B0
--> rho0(770) pi0 are measured to be (22.6 +- 1.1[stat.] +- 4.4 [syst.]) x
10^{-6} and (3.0 +- 0.5 [stat.] +- 0.7 [syst.]) x 10^{-6}, respectively. These
are the first branching fraction measurements of the process B0 --> rho(770)pi
with the lowest resonance rho(770) explicitly separated from the radial
excitations.

710.4975 | Node discovery problem for a social network | Methods to solve a node discovery problem for a social network are presented.
Covert nodes refer to the nodes which are not observable directly. They
transmit the influence and affect the resulting collaborative activities among
the persons in a social network, but do not appear in the surveillance logs
which record the participants of the collaborative activities. Discovering the
covert nodes is identifying the suspicious logs where the covert nodes would
appear if the covert nodes became overt. The performance of the methods is
demonstrated with a test dataset generated from computationally synthesized
networks and a real organization.

delta-Plutonium has been studied within the framework of density functional
theory using the full-potential linear augmented plane wave plus local basis

710.4978 | Limits of log canonical thresholds | Let T_n denote the set of log canonical thresholds of pairs (X,Y), with X a
nonsingular variety of dimension n, and Y a nonempty closed subscheme of X.
Using non-standard methods, we show that every limit of a decreasing sequence
in T_n lies in T_{n-1}, proving in this setting a conjecture of Koll\'{a}r. We
also show that T_n is a closed subset in the set of real numbers; in
particular, every limit of log canonical thresholds on smooth varieties of
fixed dimension is a rational number. As a consequence of this property, we see
that in order to check Shokurov's ACC Conjecture for all T_n, it is enough to
show that 1 is not a point of accumulation from below of any T_n. In a
different direction, we interpret the ACC Conjecture as a semi-continuity
property for log canonical thresholds of formal power series.

710.498 | Entangling the optical frequency comb: simultaneous generation of
multiple 2x2 and 2x3 continuous-variable cluster states in a single optical
parametric oscillator | We report on our research effort to generate large-scale multipartite
optical-mode entanglement using as few physical resources as possible. We have
previously shown that cluster- and GHZ-type N-partite continuous-variable
entanglement can be obtained in an optical resonator that contains a suitably
designed second-order nonlinear optical medium, pumped by at most O(N^2)
fields. In this paper, we show that the frequency comb of such a resonator can
be entangled into an arbitrary number of independent 2x2 and 2x3
continuous-variable cluster states by a single optical parametric oscillator
pumped by just a few optical modes.

Attachment with Fitness | In this paper, we provide a rigorous analysis of preferential attachment with
fitness, a random graph model introduced by Bianconi and Barabasi. Depending on
the shape of the fitness distribution, we observe three distinct phases: a

710.4984 | Josephson Current and Multiple Andreev Reflections in Graphene SNS
Junctions | The Josephson Effect and Superconducting Proximity Effect were observed in
Superconductor -Graphene-Superconductor (SGS) Josephson junctions with
coherence lengths comparable to the distance between the superconducting leads.
By comparing the measured temperature and doping dependence of the supercurrent
and the proximity induced sub-gap features (multiple Andreev reflections) to
theoretical predictions we find that, contrary to expectations, the ballistic
transport model fails to describe the SGS junctions. In contrast, the diffusive
junction model yields close quantitative agreement with the results. This
conclusion is consistent with transport measurements in the normal state, which
yield mean free paths in the graphene link that are much shorter than the
junction length. We show that all devices fabricated on SiO2 substrates so far
(our own as well as those reported by other groups) fall in the diffusive
junction category.

710.4986 | Axisymmetric toroidal modes of magnetized neutron stars | We calculate axisymmetric toroidal modes of magnetized neutron stars with a
solid crust. We assume the interior of the star is threaded by a poloidal
magnetic field that is continuous at the surface with the outside dipole field
whose strength $B_p$ at the magnetic pole is $B_p\sim 10^{16}$G. Since
separation of variables is not possible for oscillations of magnetized stars,
we employ finite series expansions of the perturbations using spherical
harmonic functions to represent the angular dependence of the oscillation
modes. For $B_p\sim 10^{16}$G, we find distinct mode sequences, in each of
which the oscillation frequency of the toroidal mode slowly increases as the
number of radial nodes of the eigenfunction increases. The frequency spectrum
of the toroidal modes for $B_p\sim 10^{16}$G is largely different from that of
the crustal toroidal modes of the non-magnetized model, although the frequency
ranges are overlapped each other. This suggests that an interpretation of the
observed QPOs based on the magnetic toroidal modes may be possible if the field
strength of the star is as strong as $B_p\sim 10^{16}$G.

710.4987 | Universal source coding over generalized complementary delivery networks | This paper deals with a universal coding problem for a certain kind of
multiterminal source coding network called a generalized complementary delivery
network. In this network, messages from multiple correlated sources are jointly
encoded, and each decoder has access to some of the messages to enable it to
reproduce the other messages. Both fixed-to-fixed length and fixed-to-variable
length lossless coding schemes are considered. Explicit constructions of

710.499 | Exploring the High-Energy Cosmic Ray Spectrum with a Toy Model of Cosmic
Ray Diffusion | We introduce a static toy model of the cosmic ray (CR) universe in which
cosmic ray propagation is taken to be diffusive and cosmic ray sources are
distributed randomly with a density the same as that of local L* galaxies, $5
\times 10^{-3}$ Mpc$^{-3}$. These sources "fire" at random times through the
history of the universe but with a set expectation time for the period between
bursts. Our toy model model captures much of the essential CR physics despite
its simplicity and, moreover, broadly reproduces CR phenomenology for
reasonable parameter values and without extreme fine-tuning. Using this model
we investigate -- and find tenable -- the idea that the Milky Way may itself be
a typical high-energy cosmic ray source. We also consider the possible
phenomenological implications of the magnetic CR horizon for the overall cosmic
ray spectrum observed at Earth. Finally, we show that anisotropy studies should

imaginary quadratic fields over $\mathbb{Q}(\sqrt{-m})$ for all m. For each
imaginary quadratic field $\mathbb{Q}(\sqrt{-m})$, we obtain a criterion on
universality of Hermitian lattices: if a Hermitian lattice L represents 1, 2,

710.4992 | Nonminimal isotropic cosmological model with Yang-Mills and Higgs fields | We establish a nonminimal Einstein-Yang-Mills-Higgs model, which contains six
coupling parameters. First three parameters relate to the nonminimal coupling
of non-Abelian gauge field and gravity field, two parameters describe the
so-called derivative nonminimal coupling of scalar multiplet with gravity
field, and the sixth parameter introduces the standard coupling of scalar field
with Ricci scalar. The formulated six-parameter nonminimal
Einstein-Yang-Mills-Higgs model is applied to cosmology. We show that there
exists a unique exact cosmological solution of the de Sitter type for a special
choice of the coupling parameters. The nonminimally extended Yang-Mills and
Higgs equations are satisfied for arbitrary gauge and scalar fields, when the
coupling parameters are specifically related to the curvature constant of the
isotropic spacetime. Basing on this special exact solution we discuss the
problem of a hidden anisotropy of the Yang-Mills field, and give an explicit

710.4996 | Large scale dynamics of the Persistent Turning Walker model of fish
behavior | This paper considers a new model of individual displacement, based on fish
motion, the so-called Persistent Turning Walker (PTW) model, which involves an
Ornstein-Uhlenbeck process on the curvature of the particle trajectory. The
goal is to show that its large time and space scale dynamics is of diffusive
type, and to provide an analytic expression of the diffusion coefficient. Two
methods are investigated. In the first one, we compute the large time
asymptotics of the variance of the individual stochastic trajectories. The
second method is based on a diffusion approximation of the kinetic formulation
of these stochastic trajectories. The kinetic model is a Fokker-Planck type
equation posed in an extended phase-space involving the curvature among the
kinetic variables. We show that both methods lead to the same value of the
diffusion constant. We present some numerical simulations to illustrate the
theoretical results.

710.4997 | Age-structured Trait Substitution Sequence Process and Canonical
Equation | We are interested in a stochastic model of trait and age-structured
population undergoing mutation and selection. We start with a continuous time,
discrete individual-centered population process. Taking the large population
and rare mutations limits under a well-chosen time-scale separation condition,
we obtain a jump process that generalizes the Trait Substitution Sequence
process describing Adaptive Dynamics for populations without age structure.
Under the additional assumption of small mutations, we derive an age-dependent
ordinary differential equation that extends the Canonical Equation. These
evolutionary approximations have never been introduced to our knowledge. They
are based on ecological phenomena represented by PDEs that generalize the
Gurtin-McCamy equation in Demography. Another particularity is that they
involve a fitness function, describing the probability of invasion of the
resident population by the mutant one, that can not always be computed
explicitly. Examples illustrate how adding an age-structure enrich the
modelling of structured population by including life history features such as
senescence. In the cases considered, we establish the evolutionary
approximations and study their long time behavior and the nature of their
evolutionary singularities when computation is tractable. Numerical procedures
and simulations are carried.

710.5 | Diagrammatic quantum field formalism for localized electrons | We introduce a diagrammatic quantum field formalism for the evaluation of
normalized expectation values of operators, and suitable for systems with
localized electrons. It is used to develop a convergent series expansion for
the energy in powers of overlap integrals of single-particle orbitals. This
method gives intuitive and practical rules for writing down the expansion to
arbitrary order of overlap, and can be applied to any spin configuration and to
any dimension. Its applicability for systems with well localized electrons has

710.5002 | The entropy of keys derived from laser speckle | Laser speckle has been proposed in a number of papers as a high-entropy
source of unpredictable bits for use in security applications. Bit strings
derived from speckle can be used for a variety of security purposes such as
identification, authentication, anti-counterfeiting, secure key storage, random
number generation and tamper protection. The choice of laser speckle as a
source of random keys is quite natural, given the chaotic properties of
speckle. However, this same chaotic behaviour also causes reproducibility
problems. Cryptographic protocols require either zero noise or very low noise
in their inputs; hence the issue of error rates is critical to applications of
laser speckle in cryptography. Most of the literature uses an error reduction
method based on Gabor filtering. Though the method is successful, it has not
been thoroughly analysed.
In this paper we present a statistical analysis of Gabor-filtered speckle
patterns. We introduce a model in which perturbations are described as random
phase changes in the source plane. Using this model we compute the second and
fourth order statistics of Gabor coefficients. We determine the mutual
information between perturbed and unperturbed Gabor coefficients and the bit
error rate in the derived bit string. The mutual information provides an
absolute upper bound on the number of secure bits that can be reproducibly
extracted from noisy measurements.

710.5003 | Tracer density discontinuities in turbulent flows: simple model and
scaling laws | Mixing in fully developed incompressible turbulent flows is known to lead to
a cascade of discontinuity fronts of passive scalar fields. A one-dimensional
(1D) variant of Baker's map is developed, capturing the main mechanism
responsible for the emergence of these discontinuities. For this 1D model,
expressions for the height-distribution function of the discontinuity fronts
and structure function scaling exponents $\zeta_p$ are derived [for Kolmogorov
turbulence, $\zeta_p=\frac 23\log_3(p+1)$]. These analytic findings are in a
good agreement with both our 1D simulations, and the results of earlier
numerical and experimental studies.

710.5004 | Computer-intensive rate estimation, diverging statistics and scanning | A general rate estimation method is proposed that is based on studying the
in-sample evolution of appropriately chosen diverging/converging statistics.
The proposed rate estimators are based on simple least squares arguments, and
are shown to be accurate in a very general setting without requiring the choice
of a tuning parameter. The notion of scanning is introduced with the purpose of
extracting useful subsamples of the data series; the proposed rate estimation
method is applied to different scans, and the resulting estimators are then
combined to improve accuracy. Applications to heavy tail index estimation as
well as to the problem of estimating the long memory parameter are discussed; a
small simulation study complements our theoretical results.

710.5005 | Struggles with Survey Weighting and Regression Modeling | The general principles of Bayesian data analysis imply that models for survey
responses should be constructed conditional on all variables that affect the
probability of inclusion and nonresponse, which are also the variables used in
survey weighting and clustering. However, such models can quickly become very
complicated, with potentially thousands of poststratification cells. It is then
a challenge to develop general families of multilevel probability models that
yield reasonable Bayesian inferences. We discuss in the context of several
ongoing public health and social surveys. This work is currently open-ended,

710.5006 | CANE: The Content Addressed Network Environment | The fragmented nature and asymmetry of local and remote file access and
network access, combined with the current lack of robust authenticity and
privacy, hamstrings the current internet. The collection of disjoint and often
ad-hoc technologies currently in use are at least partially responsible for the
magnitude and potency of the plagues besetting the information economy, of
which spam and email borne virii are canonical examples. The proposed
replacement for the internet, Internet Protocol Version 6 (IPv6), does little
to tackle these underlying issues, instead concentrating on addressing the
technical issues of a decade ago.
This paper introduces CANE, a Content Addressed Network Environment, and
compares it against current internet and related technologies. Specifically,
CANE presents a simple computing environment in which location is abstracted
away in favour of identity, and trust is explicitly defined. Identity is
cryptographically verified and yet remains pervasively open in nature. It is
argued that this approach is capable of being generalised such that file
storage and network access can be unified and subsequently combined with human
interfaces to result in a Unified Theory of Access, which addresses many of the
significant problems besetting the internet community of the early 21st
century.

710.5007 | Sub-threshold production of $\Sigma$(1385) baryons in Al+Al collisions
at 1.9$A$ GeV | First measurement of sub-threshold $\Sigma$(1385) production is presented.
Experimental data are presented for Al+Al reactions at 1.9$A$ GeV measured with
the FOPI detector at SIS/GSI. The $\Sigma$(1385)/$\Lambda$ ratio is found to be
in good agreement with the transport and statistical model predictions. The
results allow for a better understanding of sub-threshold strangeness

710.5008 | Transport and magnetic properties in YBaCo2O5.45: Focus on the
high-temperature transition | The electronic transport properties and the magnetic susceptibility were
measured in detail in $YBaCo_2O_{5.45}$. Close to the so-called metal-insulator
transition, strong effects of resistance relaxation, a clear thermal hysteresis
and a sudden increase of the resistance noise are observed. This is likely due
to the first order character of the transition and to the underlying phases
coexistence. Despite these out of equilibrium features, a positive and linear
magneto-resistance is also observed, possibly linked to the heterogeneity of
the state. From a magnetic point of view, the paramagnetic to ordered magnetic
state transition is observed using non linear susceptibilty. This transition
shows the characteristics of a continuous transition, and time dependent
effects can be linked with the dynamics of magnetic domains in presence of
disorder. Thus, when focusing on the order of the transitions, the electronic
one and the magnetic one can not be directly associated.

710.501 | EOS of dense matter and fast rotation of neutron stars | Recent observations of XTE J1739-285 suggest that it contains a neutron star
rotating at 1122 Hz. Such rotational frequency would be the first for which the
effects of rotation are significant. We study the consequences of very fast

710.5011 | A precursor state to unconventional superconductivity in CeIrIn${_5}$ | We present sensitive measurements of the Hall effect and magnetoresistance in
CeIrIn${_5}$ down to temperatures of 50 mK and magnetic fields up to 15 T. The
presence of a low temperature coherent Kondo state is established. Deviations
from Kohler's rule and a quadratic temperature dependence of the cotangent of
the Hall angle are reminiscent of properties observed in the high temperature
superconducting cuprates. The most striking observation pertains to the
presence of a \textit{precursor} state--characterized by a change in the Hall
mobility--that appears to precede the superconductivity in this material, in
similarity to the pseudogap in the cuprate high $T_c$ superconductors.

710.5014 | On $k$-noncrossing partitions | In this paper we prove a duality between $k$-noncrossing partitions over
$[n]=\{1,...,n\}$ and $k$-noncrossing braids over $[n-1]$. This duality is
derived directly via (generalized) vacillating tableaux which are in
correspondence to tangled-diagrams \cite{Reidys:07vac}. We give a combinatorial
interpretation of the bijection in terms of the contraction of arcs of
tangled-diagrams. Furthermore it induces by restriction a bijection between
$k$-noncrossing, 2-regular partitions over $[n]$ and $k$-noncrossing braids
without isolated points over $[n-1]$. Since braids without isolated points
correspond to enhanced partitions this allows, using the results of
\cite{MIRXIN}, to enumerate 2-regular, 3-noncrossing partitions.

710.5017 | Coherent states, constraint classes, and area operators in the new
spin-foam models | Recently, two new spin-foam models have appeared in the literature, both
motivated by a desire to modify the Barrett-Crane model in such a way that the
imposition of certain second class constraints, called cross-simplicity
constraints, are weakened. We refer to these two models as the FKLS model, and
the flipped model. Both of these models are based on a reformulation of the
cross-simplicity constraints. This paper has two main parts. First, we clarify
the structure of the reformulated cross-simplicity constraints and the nature
of their quantum imposition in the new models. In particular we show that in
the FKLS model, quantum cross-simplicity implies no restriction on states. The
deeper reason for this is that, with the symplectic structure relevant for
FKLS, the reformulated cross-simplicity constraints, in a certain relevant
sense, are now \emph{first class}, and this causes the coherent state method of
imposing the constraints, key in the FKLS model, to fail to give any
restriction on states. Nevertheless, the cross-simplicity can still be seen as
implemented via suppression of intertwiner degrees of freedom in the dynamical
propagation. In the second part of the paper, we investigate area spectra in
the models. The results of these two investigations will highlight how, in the
flipped model, the Hilbert space of states, as well as the spectra of area
operators exactly match those of loop quantum gravity, whereas in the FKLS (and
Barrett-Crane) models, the boundary Hilbert spaces and area spectra are
different.

710.5018 | Some remarks on Pr\"{u}fer $\star $--multiplication domains and class
groups | Let $D$ be an integral domain with quotient field $K$ and let $X$ be an
indeterminate over $D$. Also, let $\boldsymbol{\mathcal{T}}:=\{T_{\lambda}\mid
\lambda
\in \Lambda \}$ be a defining family of quotient rings of $D$ and suppose
that $\ast $ is a finite type star operation on $D$ induced by
$\boldsymbol{\mathcal{T}}$. We show that $D$ is a P$ \ast $MD (resp., P$v$MD)
if and only if $(\co_D(fg))^{\ast}=(\co_D(f)\co_D(g))^{\ast}$ (resp.,
$(\co_D(fg))^{w}=(\co_D(f)\co_D(g))^{w}$) for all $0 \ne f,g \in K[X]$. A more
general version of this result is given in the semistar operation setting. We
give a method for recognizing P$v$MD's which are not P$\ast $MD's for a certain
finite type star operation $\ast $. We study domains $D$ for which the $\ast
$--class group $\Cl^{\ast}(D)$ equals the $t$--class group $\Cl^{t}(D)$ for any
finite type star operation $\ast $, and we indicate examples of P$v$MD's $D$

710.5021 | On the first integral conjecture of Rene Thom | More that half a century ago R. Thom asserted in an unpublished manuscript
that, generically, vector fields on compact connected smooth manifolds without
boundary can admit only trivial continuous first integrals. Though somehow
unprecise for what concerns the interpretation of the word \textquotedblleft
generically\textquotedblright, this statement is ostensibly true and is
nowadays commonly accepted. On the other hand, the (few) known formal proofs of
Thom's conjecture are all relying to the classical Sard theorem and are thus
requiring the technical assumption that first integrals should be of class
$C^{k}$ with $k\geq d,$ where $d$ is the dimension of the manifold. In this
work, using a recent nonsmooth extension of Sard theorem we establish the

710.5022 | Star Formation History in the Galactic Thin Disk | The behavior of the relative magnesium abundances in the thin-disk stars
versus their orbital radii suggests that the star formation rate in the thin
disk decreases with increasing Galactocentric distance, and there was no star
formation for some time outside the solar circle while this process was
continuous within the solar circle. The decrease in the star formation rate
with increasing Galactocentric distance is responsible for the existence of a
negative radial metallicity gradient in the thin disk. At the same time the
relative magnesium abundance exhibits no radial gradient. It is in detail
considered the influence of selective effects on the form of both age -
metallicity and age - relative magnesium abundance diagrams. It is shown that
the first several billion years of the formation of the thin disk interstellar
medium in it was on the average sufficiently rich in heavy elements (<[Fe/H]> =
-0.22), badly mixed (\sigma_[Fe/H] = 0.21), and the average relative magnesium
abundance was comparatively high (<[Mg/Fe]> = 0.10). Approximately 5 billion
years ago average metallicity began to systematically increase, and its
dispersion and the average relative magnesium abundance - to decrease. These
properties may be explained by an increase in star formation rate with the
simultaneous intensification of the processes of mixing the interstellar medium
in the thin disk, provoke possible by interaction the Galaxy with the
completely massive by satellite galaxy.

710.5023 | Observations and asteroseismic analysis of the rapidly pulsating hot B
subdwarf PG 0911+456 | The principal aim of this project is to determine the structural parameters
of the rapidly pulsating subdwarf B star PG 0911+456 from asteroseismology. Our
work forms part of an ongoing programme to constrain the internal
characteristics of hot B subdwarfs with the long-term goal of differentiating
between the various formation scenarios proposed for these objects. First
comparisons of asteroseismic values with evolutionary theory look promising,
however it is clear that more targets are needed for meaningful statistics to
be derived. The observational pulsation periods of PG 0911+456 were extracted
from rapid time-series photometry using standard Fourier analysis techniques.
Supplemented by spectroscopic estimates of the star's mean atmospheric
parameters, they were used as a basis for the "forward modelling" approach in
asteroseismology. The latter culminates in the identification of one or more
"optimal" models that can accurately reproduce the observed period spectrum.
This naturally leads to an identification of the oscillations detected in terms
of degree l and radial order k, and infers the structural parameters of the
target. From the photometry it was possible to extract 7 independent pulsation
periods in the 150-200 s range with amplitudes between 0.05 and 0.8 % of the
star's mean brightness. An asteroseismic search of parameter space identified
several models that matched the observed properties of PG 0911+456 well, one of
which was isolated as the "optimal" model on the basis of spectroscopic and
mode identification considerations. All the observed pulsations are identified
with low-order acoustic modes with degree indices l=0,1,2 and 4, and match the
computed periods with a dispersion of only ~0.26 %.

710.5024 | On fractional Ornstein-Uhlenbeck processes | In this paper we study Doob's transform of fractional Brownian motion (FBM).
It is well known that Doob's transform of standard Brownian motion is identical
in law with the Ornstein-Uhlenbeck diffusion defined as the solution of the
(stochastic) Langevin equation where the driving process is a Brownian motion.
It is also known that Doob's transform of FBM and the process obtained from the
Langevin equation with FBM as the driving process are different. However, also
the first one of these can be described as a solution of a Langevin equation
but now with some other driving process than FBM. We are mainly interested in
the properties of this new driving process denoted Y^{(1)}. We also study the
solution of the Langevin equation with Y^{(1)} as the driving process.
Moreover, we show that the covariance of Y^{(1)} grows linearly; hence, in this
respect Y^{(1)} is more like a standard Brownian motion than a FBM. In fact, it
is proved that a properly scaled version of Y^{(1)} converges weakly to
Brownian motion.

710.5026 | The Parkes Pulsar Timing Array | Detection and study of gravitational waves from astrophysical sources is a
major goal of current astrophysics. Ground-based laser-interferometer systems
such as LIGO and VIRGO are sensitive to gravitational waves with frequencies of
order 100 Hz, whereas space-based systems such as LISA are sensitive in the
millihertz regime. Precise timing observations of a sample of millisecond
pulsars widely distributed on the sky have the potential to detect
gravitational waves at nanohertz frequencies. Potential sources of such waves
include binary super-massive black holes in the cores of galaxies, relic
radiation from the inflationary era and oscillations of cosmic strings. The
Parkes Pulsar Timing Array (PPTA) is an implementation of such a system in
which 20 millisecond pulsars have been observed using the Parkes radio
telescope at three frequencies at intervals of two -- three weeks for more than
two years. Analysis of these data has been used to limit the gravitational wave
background in our Galaxy and to constrain some models for its generation. The
data have also been used to investigate fluctuations in the interstellar and
Solar-wind electron density and have the potential to investigate the stability
of terrestrial time standards and the accuracy of solar-system ephemerides.

relic radiation from the inflationary era and oscillations of cosmic strings the parkes pulsar timing array ppta is an implementation of such a system in which 20 millisecond pulsars have been observed using the parkes radio telescope at three frequencies at intervals of two three weeks for more than two years analysis of these data has been used to limit the gravitational wave background in our galaxy and to constrain some models for its generation the data have also been used to investigate fluctuations in the interstellar and solarwind electron density and have the potential to investigate the stability of terrestrial time standards and the accuracy of solarsystem ephemerides | [['detection', 'and', 'study', 'of', 'gravitational', 'waves', 'from', 'astrophysical', 'sources',

710.5028 | The CORALIE survey for southern extra-solar planets XV. Discovery of two
eccentric planets orbiting HD4113 and HD156846 | We report the detection of two very eccentric planets orbiting HD4113 and
HD156846 with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss
telescope at La Silla. The first planet, HD4113b, has minimum mass of
$m\sin{i}=1.6\pm0.2 M_{\rm Jup}$, a period of $P=526.59\pm0.21$ days and an
eccentricity of $e=0.903\pm0.02$. It orbits a metal rich G5V star at $a=1.28$
AU which displays an additional radial velocity drift of 28 m s$^{-1}$/yr
observed during 8 years. The combination of the radial-velocity data and the
non-detection of any main sequence stellar companion in our high contrast
images taken at the VLT with NACO/SDI, characterizes the companion as a
probable brown dwarf or as a faint white dwarf. The second planet, \object{HD
156846 b}, has minimum mass of $m\sin{i}=10.45\pm0.05$ M$_{\rm Jup}$, a period
of $P=359.51\pm0.09 $ days, an eccentricity of $e=0.847\pm0.002$ and is located
at $a=1.0$ AU from its parent star. HD156846 is a metal rich G0 dwarf and is
also the primary of a wide binary system ($a>250$ AU, $P>4000$ years). Its
stellar companion, \object{IDS 17147-1914 B}, is a M4 dwarf. The very high
eccentricities of both planets can be explained by Kozai oscillations induced
by the presence of a third object.

710.503 | High-resolution spectroscopy of the R Coronae Borealis Star V Coronae
Australis | Optical high-resolution spectra of the R Coronae Borealis star V CrA at light
maximum and during minimum light arediscussed. Abundance analysis confirms
previous results showing that V CrA has the composition of the small subclass
of R Coronae Borealis (RCB) stars know as `minority' RCBs, i.e., the Si/Fe and
S/Fe ratios are 100 times their solar values.
A notable novel result for RCBs is the detection of the 1-0 Swan system
$^{12}$C$^{13}$C bandhead indicating that $^{13}$C is abundant: spectrum
synthesis shows that $^{12}$C/$^{13}$C is about 3 to 4. Absorption line
profiles are variable at maximum light with some lines showing evidence of
splitting by about 10 km s$^{-1}$. A spectrum obtained as the star was
recovering from a deep minimum shows the presence of cool C$_2$ molecules with
a rotational temperature of about 1200K, a temperature suggestive of gas in
which carbon is condensing into soot. The presence of rapidly outflowing gas is
shown by blue-shifted absorption components of the Na {\sc i} D and K {\sc i}
7698 \AA resonance lines.

710.5031 | Elementary Pseudoconcavity and fields of CR meromorphic functions | Let M be a smooth CR manifold of CR dimension n and CR codimension k, which
is not compact, but has the local extension property E. We introduce the notion
of "elementary pseudoconcavity" for M, which extends to CR manifolds the
concept of a "pseudoconcave" complex manifold. This notion is then used to
obtain generalizations, to the noncompact case, of the results of our previous

710.5034 | Numerical indications on the semiclassical limit of the flipped vertex | We introduce a technique for testing the semiclassical limit of a quantum
gravity vertex amplitude. The technique is based on the propagation of a
semiclassical wave packet. We apply this technique to the newly introduced
"flipped" vertex in loop quantum gravity, in order to test the intertwiner
dependence of the vertex. Under some drastic simplifications, we find very

710.5035 | The NIR to UV continuum of radio loud vs. radio quiet quasars | Starting from a sample of SDSS quasars appearing also in the 2MASS survey, we
study the continuum properties of about 1000 objects observed in 8 bands, from
NIR to UV. We construct the mean spectral energy distribution (SED) and compare
and contrast the continua of radio loud (RLQ) and radio quiet (RQQ) objects.
The SEDs of the two populations are significantly different in the sense that
RLQs are redder, with power law spectral indices <alpha(RLQ)>=-0.55+/-0.04 and
<alpha(RQQ)>=-0.31+/-0.01 in the spectral range between 10^14.5 and 10^15.35
Hz. This difference is discussed in terms of different extinctions, different
disc temperatures, or slopes of the non-thermal component.

710.5036 | Accretion indicators for the 37 brightest radio sources in the
Subaru/XMM-Newton Deep Field | We study the 37 brightest radio sources in the Subaru/XMM-Newton Deep Field
(SXDF). Using mid-IR (Spitzer MIPS 24 micron) data we expect to trace nuclear
accretion activity, even if it is obscured at optical wavelengths, unless the
obscuring column is extreme. Our results suggest that above the `FRI/FRII'
radio luminosity break most of the radio sources are associated with objects
that have excess mid-IR emission, only some of which are broad-line objects,
although there is one clear low-accretion-rate FRI. The fraction of objects
with mid-IR excess drops dramatically below the FRI/FRII break, although there
exists at least one high-accretion-rate QSO. Investigation of mid-IR and blue
excesses shows that they are correlated as predicted by a model in which a

710.5038 | Higgs boson productions at LHC as a probe of different littlest Higgs
models with T-parity | Higgs boson productions at the LHC will serve as a sensitive probe of various
little Higgs models. In this work we comparatively study two littlest Higgs
models with different T-parity constructions through examining their effects in
three production processes of the Higgs boson at the LHC, namely the
productions of a single Higgs, a Higgs-pair, as well as a Higgs boson
associated with a pair of top and anti-top quarks. The two models are
characterized by predicting a top partner canceling the Higgs mass quadratic
divergence contributed by the top quark with even and odd T-parity,
respectively. We find that both models can alter the SM cross sections sizably
and their corrections also differ significantly. Therefore, the Higgs boson

710.5039 | On the separability criterion for continuous variable systems | We present an elementary and explicit proof of the separability criterion for
continuous variable two-party Gaussian systems. Our proof is based on an
elementary formulation of uncertainty relations and an explicit determination
of squeezing parameters for which the P-representation condition saturates the
$Sp(2,R)\otimes Sp(2,R)$ invariant separability condition. We thus give the
explicit formulas of squeezing parameters, which establish the equivalence of
the separability condition with the P-representation condition, in terms of the
parameters of the standard form of the correlation matrix. Our proof is
compared to the past proofs, and it is pointed out that the original proof of
the P-representation by Duan, Giedke, Cirac and Zoller(DGCZ) is incomplete. A
way to complete their proof is then shown. It is noted that both of the
corrected proof of DGCZ and the proof of R. Simon are closely related to our
explicit construction despite their quite different appearances.

710.504 | Verification of new identity for the Green functions in N=1
supersymmetric non-Abelian Yang--Mills theory with the matter fields | We investigate a new identity for Green functions using the higher covariant
derivative regularization. It relates some coefficients in the vertex function
of the matter superfield, in which one of external matter lines is not chiral.
The calculation in the first nontrivial order (for the two-loop vertex
function) reveals that the new identity is also valid for the non-Abelian
Yang--Mills theory with matter fields. The new identity is shown to appear

710.5043 | Lorentzian LQG vertex amplitude | We generalize a model recently proposed for Euclidean quantum gravity to the
case of Lorentzian signature. The main features of the Euclidean model are
preserved in the Lorentzian one. In particular, the boundary Hilbert space
matches the one of SU(2) loop quantum gravity. As in the Euclidean case, the
model can be obtained from the Lorentzian Barrett-Crane model from a flipping

710.5045 | Statistical approach to dislocation dynamics: From dislocation
correlations to a multiple-slip continuum plasticity theory | Due to recent successes of a statistical-based nonlocal continuum crystal
plasticity theory for single-glide in explaining various aspects such as
dislocation patterning and size-dependent plasticity, several attempts have
been made to extend the theory to describe crystals with multiple slip systems
using ad-hoc assumptions. We present here a mesoscale continuum theory of
plasticity for multiple slip systems of parallel edge dislocations. We begin by
constructing the Bogolyubov-Born-Green-Yvon-Kirkwood (BBGYK) integral equations
relating different orders of dislocation correlation functions in a grand
canonical ensemble. Approximate pair correlation functions are obtained for
single-slip systems with two types of dislocations and, subsequently, for
general multiple-slip systems of both charges. The effect of the correlations
manifests itself in the form of an entropic force in addition to the external
stress and the self-consistent internal stress. Comparisons with a previous
multiple-slip theory based on phenomenological considerations shall be
discussed.

foundational works by Sean M. Carroll and Jennifer Chen, "Does Inflation
Provide Natural Conditions for the Universe" and "Spontaneous Inflation and the
Origin of the Arrow of Time", in order to evaluate their comparative treatments
of the nature and role of causality, time ordering, thermodynamic
reversibility, singularities and boundary conditions in the formation of the
early universe. We briefly reference Smolin and Kauffman's recent arguments
with respect to possible processes of "evolutionary selection" in early
universe formation as an alternative explanation to key elements of Hawking's
earlier "M-Theory", and its attendant anthropic principle. We also briefly
excerpt a short section of Smolin's recent work on topology in quantum loop
gravity, simply as an illustrative example of the type of complex quantum
topological transformation which he offers as a theoretical alternative to
string theory in quantum cosmology.

710.5047 | Kinematic structure of the atmosphere and envelope of the post-AGB star
HD56126 | We present results of an analysis of the optical spectrum of the post-AGB
star HD56126 (IRAS 07134+1005) based on observations made with the echelle
spectrographs of the 6-m telescope with spectral resolutions of R=25000 and
60000 at 4012-8790 AA. The profiles of strongest lines (HI; FeII, YII, BaII
absorptions, etc.) formed in the expanding atmosphere at the base of the
stellar wind have complex and variable shapes. To study the kinematics of the
atmosphere, the velocities of individual features in these profiles must be
measured. Differential line shifts of up to Vr=15-30 km/s have been detected
from the lines of metals and molecular features. The star's atmosphere
simultaneously contains both expanding layers and layers falling onto the star.
A comparison of the data for different times demonstrates that both the radial
velocity and the velocity pattern in whole are variable. The position of the
molecular spectrum is stable, implying stability of the expansion velocity of
the circumstellar envelope around HD56126 detected in observations in the C_2
and NaI lines.

spaces where we expand the regular solution of the 1D time-independent
Schrodinger equation in terms of square integrable bases. We also require that
the basis support an infinite tridiagonal matrix representation of the wave
operator. By this requirement, we deduce a class of solvable potentials along
with their corresponding bound states and stationary wavefunctions expressed as
infinite series in terms of these bases. This approach allows for simultaneous
treatment of the discrete (bound states) as well as the continuous (scattering
states) spectrum on the same footing. The problem translates into finding
solutions of the resulting three-term recursion relation for the expansion
coefficients of the wavefunction. These are written in terms of orthogonal
polynomials, some of which are modified versions of known polynomials. The
examples given, which are not exhaustive, illustrate the power of this approach
in dealing with 1D quantum problems.

710.5051 | Localization of Gauge Fields and Monopole Tunnelling | We study the dynamical localization of a massless gauge field on a
lower-dimensional surface (2-brane). In flat space, the necessary and
sufficient condition for this phenomenon is the existence of confinement in the
bulk. The resulting configuration is equivalent to a dual Josephson junction.
This duality leads to an interesting puzzle, as it implies that a localized
massless theory, even in the Abelian case, must become confining at
exponentially large distances. Through the use of topological arguments we
clarify the physics behind this large-distance confinement and identify the
instantons of the brane world-volume theory that are responsible for its
appearance. We show that they correspond to the (condensed) bulk magnetic
charges (monopoles), that occasionally tunnel through the brane and induce weak
confinement of the brane theory. We consider the possible generalization of
this effect to higher dimensions and discuss phenomenological bounds on the

710.5052 | Magnetic fluctuations and formation of large-scale inhomogeneous
magnetic structures in a turbulent convection | Magnetic fluctuations generated by a tangling of the mean magnetic field by
velocity fluctuations are studied in a developed turbulent convection with
large magnetic Reynolds numbers. We show that the energy of magnetic
fluctuations depends on magnetic Reynolds number only when the mean magnetic
field is smaller than $B_{eq} / 4 Rm^{1/4}$, where $B_{eq}$ is the
equipartition mean magnetic field determined by the turbulent kinetic energy
and Rm is magnetic Reynolds number. Generation of magnetic fluctuations in a
turbulent convection with a nonzero mean magnetic field results in a decrease
of the total turbulent pressure and may cause formation of the large-scale
inhomogeneous magnetic structures even in an originally uniform mean magnetic
field. This effect is caused by a negative contribution of the turbulent
convection to the effective mean Lorentz force. The inhomogeneous large-scale
magnetic fields are formed due to the excitation of the large-scale
instability. The energy for this instability is supplied by the small-scale
turbulent convection. The discussed effects might be useful for understanding
the origin of the solar nonuniform magnetic fields, e.g., sunspots.
