710.4153 | Quantum Indeterminacy of Emergent Spacetime | It is shown that nearly-flat 3+1D spacetime emerging from a dual quantum
field theory in 2+1D displays quantum fluctuations from classical Euclidean
geometry on macroscopic scales. A covariant holographic mapping is assumed,
where plane wave states with wavevector k on a 2D surface map onto classical
null trajectories in the emergent third dimension at an angle \theta=l_P k
relative to the surface element normal, where l_P denotes the Planck length.
Null trajectories in the 3+1D world then display quantum uncertainty of angular
orientation, with standard deviation \Delta\theta=\sqrt{l_P/z} for longitudinal
propagation distance z in a given frame. The quantum complementarity of
transverse position at macroscopically separated events along null trajectories
corresponds to a geometry that is not completely classical, but displays
observable holographic quantum noise. A statistical estimator of the
fluctuations from Euclidean behavior is given for a simple thought experiment
based on measured sides of triangles. The effect can be viewed as sampling
noise due to the limited degrees of freedom of such a theory, consistent with
covariant bounds on entropy.

710.4154 | Spin phonon coupling in frustrated magnet CdCr$_2$O$_4$ | The infrared phonon spectrum of the spinel CdCr2O4 is measured as a function
temperature from 6 K to 300K. The triply degenerate Cr phonons soften in the
paramagnetic phase as temperature is lowered below 100 K and then split into a
singlet and doublet in the low T antiferromagnetic phase which is tetragonally
distorted to relieve the geometric frustration in the pyrochlore lattice of
Cr$^{3+}$ ions. The phonon splitting is inconsistent with the simple increase
(decrease) in the force constants due to deceasing (increasing) bond lengths in
the tetragonal phase. Rather they correspond to changes in the force constants
due to the magnetic order in the antiferromagnetic state. The phonon splitting
in this system is opposite of that observed earlier in ZnCr2O4 as predicted by
theory. The magnitude of the splitting gives a measure of the spin phonon
coupling strength which is smaller than in the case of ZnCr2O4.

710.4155 | Hook-content formulae for symplectic and orthogonal tableaux | By considering the specialisation $s_{\lambda}(1,q,q^2,...,q^{n-1})$ of the
Schur function, Stanley was able to describe a formula for the number of
semistandard Young tableaux of shape $\lambda$ in terms of two properties of
the boxes in the diagram for $\lambda$. Using specialisations of symplectic and
orthogonal Schur functions, we derive corresponding formulae, first given by El

710.4157 | A Cross-Match of 2MASS and SDSS: Newly-Found L and T Dwarfs and an
Estimate of the Space Densitfy of T Dwarfs | We report new L and T dwarfs found in a cross-match of the SDSS Data Release
1 and 2MASS. Our simultaneous search of the two databases effectively allows us
to relax the criteria for object detection in either survey and to explore the
combined databases to a greater completeness level. We find two new T dwarfs in
addition to the 13 already known in the SDSS DR1 footprint. We also identify 22
new candidate and bona-fide L dwarfs, including a new young L2 dwarf and a
peculiar L2 dwarf with unusually blue near-IR colors: potentially the result of
mildly sub-solar metallicity. These discoveries underscore the utility of
simultaneous database cross-correlation in searching for rare objects. Our
cross-match completes the census of T dwarfs within the joint SDSS and 2MASS
flux limits to the 97% level. Hence, we are able to accurately infer the space
density of T dwarfs. We employ Monte Carlo tools to simulate the observed
population of SDSS DR1 T dwarfs with 2MASS counterparts and find that the space
density of T0-T8 dwarf systems is 0.0070 (-0.0030; +0.0032) per cubic parsec
(95% confidence interval), i.e., about one per 140 cubic parsecs. Compared to
predictions for the T dwarf space density that depend on various assumptions
for the sub-stellar mass function, this result is most consistent with models
that assume a flat sub-stellar mass function dN/dM ~ M^0. No >T8 dwarfs were
discovered in the present cross-match, though less than one was expected in the
limited area (2099 sq. degrees) of SDSS DR1.

710.4158 | The Highest Energy Neutrinos | Measurements of the arrival directions of cosmic rays have not revealed their
sources. High energy neutrino telescopes attempt to resolve the problem by
detecting neutrinos whose directions are not scrambled by magnetic fields. The
key issue is whether the neutrino flux produced in cosmic ray accelerators is
detectable. It is believed that the answer is affirmative, both for the
galactic and extragalactic sources, provided the detector has kilometer-scale
dimensions. We revisit the case for kilometer-scale neutrino detectors in a
model-independent way by focussing on the energetics of the sources. The real
breakthrough though has not been on the theory but on the technology front: the
considerable technical hurdles to build such detectors have been overcome.
Where extragalactic cosmic rays are concerned an alternative method to probe
the accelerators consists in studying the arrival directions of neutrinos
produced in interactions with the microwave background near the source, i.e.
within a GZK radius. Their flux is calculable within large ambiguities but, in
any case, low. It is therefore likely that detectors that are larger yet by
several orders of magnitudes are required. These exploit novel techniques, such
as detecting the secondary radiation at radio wavelengths emitted by neutrino
induced showers.

710.4159 | Phase Bifurcations of Strongly Correlated Electron Gas at the Conditions
of dHvA Effect | In a framework of catastrophe theory we investigate the equilibrium set for
the system of strongly correlated electron gas at the conditions of dHvA effect
and show that the discontinuities accompanied the diamagnetic phase transition
(DPT) is handled by Riemann-Hugoniot catastrophe. We show that applicability of
the standard condition for observation of DPT $a\ge$1 where $a$ is the
differential magnetic susceptibility is valid only in the nearest vicinity of
triple degenerate point corresponding to the center of dHvA period, but for
arbitrary value of magnetic field in every period of dHvA oscillations this
condition is modified in accordance with the bifurcation set of cusp
catastrophe. While at the center of dHvA period the symmetric supercritical
pitchfork bifurcation gives rise to the second order phase transition on
temperature, the deviation of magnetic field from the value corresponding to
the center of dHvA period results in the change of the phase transition order
from the second to the first one both on temperature and magnetic field. In the
framework of developed theory we obtain good agreement with available
experimental data.

710.416 | Raman spectroscopy of graphene on different substrates and influence of
defects | We show the evolution of Raman spectra with number of graphene layers on
different substrates, SiO$_{2}$/Si and conducting indium tin oxide (ITO) plate.
The G mode peak position and the intensity ratio of G and 2D bands depend on
the preparation of sample for the same number of graphene layers. The 2D Raman
band has characteristic line shapes in single and bilayer graphene, capturing
the differences in their electronic structure. The defects have a significant
influence on the G band peak position for the single layer graphene: the
frequency shows a blue shift upto 12 cm$^{-1}$ depending on the intensity of
the D Raman band, which is a marker of the defect density. Most surprisingly,
Raman spectra of graphene on the conducting ITO plates show a lowering of the G
mode frequency by $\sim$ 6 cm$^{-1}$ and the 2D band frequency by $\sim$ 20

710.4162 | Impact of reionization on CMB polarization tests of slow-roll inflation | Estimates of inflationary parameters from the CMB B-mode polarization
spectrum on the largest scales depend on knowledge of the reionization history,
especially at low tensor-to-scalar ratio. Assuming an incorrect reionization
history in the analysis of such polarization data can strongly bias the
inflationary parameters. One consequence is that the single-field slow-roll
consistency relation between the tensor-to-scalar ratio and tensor tilt might
be excluded with high significance even if this relation holds in reality. We
explain the origin of the bias and present case studies with various tensor
amplitudes and noise characteristics. A more model-independent approach can
account for uncertainties about reionization, and we show that parametrizing
the reionization history by a set of its principal components with respect to
E-mode polarization removes the bias in inflationary parameter measurement with
little degradation in precision.

710.4163 | Achernar: Rapid Polarization Variability as Evidence of Photospheric and
Circumstellar Activity | We present the results of a high accuracy ($\sigma \approx 0.005%$)
polarization monitoring of the Be Star Achernar that was carried out between
July 7th and November 5th, 2006. Our results indicate that, after a near
quiescent phase from 1998 to 2002, Achernar is presently in an active phase and
has built a circumstellar disk. We detect variations both in the polarization
level and position angle in timescales as short as one hour and as long as
several weeks. Detailed modeling of the observed polarization strongly suggests
that the short-term variations originate from discrete mass ejection events
which produce transient inhomogeneities in the inner disk. Long-term
variations, on the other hand, can be explained by the formation of an inner
ring following one or several mass ejection events.

710.4164 | Morphology of Condon Domains Phase in Plate-Like Sample | Based on Shoenberg assumption of magnetic flux density dependence of
diamagnetic moments which accounts for an instability of strongly correlated
electron gas at the conditions of dHvA effect and diamagnetic phase transition
(DPT) to non-uniform phase, we investigate the morphology of the Condon domains
(CD) in plate-like sample theoretically. At one period of dHvA oscillations the
intrinsic structure of inhomogeneous diamagnetic phase (IDP) is governed by the
first order phase transitions between different non-uniform phases similar to
the high-anisotropy magnetic systems of spin origin, and strongly affected by
temperature, magnetic field and impurity of the sample due to the electron

710.4167 | A Minkowski Type Trace Inequality and Strong Subadditivity of Quantum
Entropy II: Convexity and Concavity | We revisit and prove some convexity inequalities for trace functions
conjectured in the earlier part I. The main functional considered is
\Phi_{p,q}(A_1,A_2,...,A_m) = (trace((\sum_{j=1}^m A_j^p)^{q/p}))^{1/q} for m
positive definite operators A_j. In part I we only considered the case q=1 and
proved the concavity of \Phi_{p,1} for 0 < p \leq 1 and the convexity for p=2.
We conjectured the convexity of \Phi_{p,1} for 1< p < 2. Here we not only
settle the unresolved case of joint convexity for 1 \leq p \leq 2, we are also
able to include the parameter q\geq 1 and still retain the convexity. Among
other things this leads to a definition of an L^q(L^p) norm for operators when
1 \leq p \leq 2 and a Minkowski inequality for operators on a tensor product of
three Hilbert spaces -- which leads to another proof of strong subadditivity of

710.4169 | Charged Higgs boson phenomenology in Supersymmetric models with Higgs
triplets | We present a detailed study of the Higgs sector within an extension of the
Minimal Supersymmetric Standard Model that includes one Complex Higgs Triplet
(MSSM+1CHT). The model spectrum includes three singly charged Higgs bosons as
well as three CP-even (or scalar) and two CP-odd (or pseudoscalar) neutral
Higgs bosons. We present an approximated calculation of the one-loop radiative
corrections to the neutral CP-even Higgs masses ($m_{H_i^0}$) and the couplings
$H_i^0 Z^0 Z^0$ ($i=1$, 2, 3), which determine the magnitude of the
Higgs-strahlung processes $e^+ e^-\to Z^0 H^0_i$. Limits from LEP2 are then
considered, in order to obtain bounds on the neutral Higgs sector. Further, we
also include the experimental limits from LEP2 on $e^+e^-\to H^+H^-$ and those
on BR($t \to b H^+$) from Tevatron, to derive bounds on the mass of the two
lightest charged Higgs bosons ($H_1^{\pm}$ and $H_2^{\pm}$). Concerning the
latter, we find some cases, where $m_{H_1^{\pm}} \simeq 90$ GeV, that are not

observations of the high energy-peaked BL Lac (HBL) object 1ES 1218+304 with
the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE). 1ES 1218+304
is an X-ray bright HBL at a redshift z=0.182. It has been predicted to be a
gamma-ray emitter above 100 GeV, detectable by ground-based Cherenkov
telescopes. Recently this source has been detected by MAGIC and VERITAS,
confirming these predictions. STACEE's sensitivity to astrophysical sources at
energies above 100 GeV allows it to explore high energy sources such as X-ray
bright active galaxies and gamma-ray bursts. We present results from STACEE
observations of 1ES 1218+304 in the 2006 and 2007 observing seasons.

710.4171 | Interference Cancelation in Coherent CDMA Systems Using Parallel
Iterative Algorithms | Least mean square-partial parallel interference cancelation (LMS-PPIC) is a
partial interference cancelation using adaptive multistage structure in which
the normalized least mean square (NLMS) adaptive algorithm is engaged to obtain
the cancelation weights. The performance of the NLMS algorithm is mostly
dependent to its step-size. A fixed and non-optimized step-size causes the
propagation of error from one stage to the next one. When all user channels are
balanced, the unit magnitude is the principal property of the cancelation
weight elements. Based on this fact and using a set of NLMS algorithms with
different step-sizes, the parallel LMS-PPIC (PLMS-PPIC) method is proposed. In
each iteration of the algorithm, the parameter estimate of the NLMS algorithm
is chosen to match the elements' magnitudes of the cancelation weight estimate
with unity. Simulation results are given to compare the performance of our

710.4173 | Full MIMO Channel Estimation Using A Simple Adaptive Partial Feedback
Method | Partial feedback in multiple-input multiple-output (MIMO) communication
systems provides tremendous capacity gain and enables the transmitter to
exploit channel condition and to eliminate channel interference. In the case of
severely limited feedback, constructing a quantized partial feedback is an
important issue. To reduce the computational complexity of the feedback system,
in this paper we introduce an adaptive partial method in which at the
transmitter, an easy to implement least square adaptive algorithm is engaged to
compute the channel state information. In this scheme at the receiver, the time
varying step-size is replied to the transmitter via a reliable feedback
channel. The transmitter iteratively employs this feedback information to
estimate the channel weights. This method is independent of the employed

710.4179 | On a Connection between Entropy, Extensive Measurement and Memoryless
Characterization | We define an entropy based on a chosen governing probability distribution. If
a certain kind of measurements follow such a distribution it also gives us a
suitable scale to study it with. This scale will appear as a link function that
is applied to the measurements. A link function can also be used to define an
alternative structure on a set. We will see that generalized entropies are
equivalent to using a different scale for the phenomenon that is studied
compared to the scale the measurements arrive on. An extensive measurement
scale is here a scale for which measurements fulfill a memoryless property. We
conclude that the alternative algebraic structure defined by the link function
must be used if we continue to work on the original scale. We derive Tsallis
entropy by using a generalized log-logistic governing distribution. Typical

710.418 | A quick search method for audio signals based on a piecewise linear
representation of feature trajectories | This paper presents a new method for a quick similarity-based search through
long unlabeled audio streams to detect and locate audio clips provided by
users. The method involves feature-dimension reduction based on a piecewise
linear representation of a sequential feature trajectory extracted from a long
audio stream. Two techniques enable us to obtain a piecewise linear
representation: the dynamic segmentation of feature trajectories and the
segment-based Karhunen-L\'{o}eve (KL) transform. The proposed search method
guarantees the same search results as the search method without the proposed
feature-dimension reduction method in principle. Experiment results indicate
significant improvements in search speed. For example the proposed method
reduced the total search time to approximately 1/12 that of previous methods
and detected queries in approximately 0.3 seconds from a 200-hour audio
database.

710.4181 | Thermodynamic and structural consensus principle predicts mature miRNA
location and structure, categorizes conserved interspecies miRNA subgroups,
and hints new possible mechanisms of miRNA maturization | Although conservation of thermodynamics is much less studied than of
sequences and structures, thermodynamic details are biophysical features
different from but as important as structural features. As a succession of
previous research which revealed the important relationships between
thermodynamic features and miRNA maturization, this article applies
interspecies conservation of miRNA thermodynamics and structures to study miRNA
maturization. According to a thermodynamic and structural consensus principle,
miRBase is categorized by conservation subgroups, which imply various
functions. These subgroups are divided without the introduction of functional
information. This suggests the consistency between the two processes of miRNA
maturization and functioning. Different from prevailing methods which predict
extended miRNA precursors, a learning-based algorithm is proposed to predict
~22bp mature parts of 2780 test miRNA genes in 44 species with a rate of 79.4%.
This is the first attempt of a general interspecies prediction of mature
miRNAs. Suboptimal structures that most fit the consensus thermodynamic and
structural profiles are chosen to improve structure prediction. Distribution of
miRNA locations on corresponding pri-miRNA stem-loop structures is then
studied. Existing research on Drosha cleavage site is not generally true across
species. Instead, the distance between mature miRNA and center loop normalized
by stem length is a more conserved structural feature in animals, and the
normalized distance between mature miRNA and ss-RNA tail is the counterpart in
plants. This suggests two possibly-updating mechanisms of miRNA maturization in
animals and plants. All in all, conservations of thermodynamics together with
other features are shown closely related to miRNA maturization.

710.4182 | Beyond Feedforward Models Trained by Backpropagation: a Practical
Training Tool for a More Efficient Universal Approximator | Cellular Simultaneous Recurrent Neural Network (SRN) has been shown to be a
function approximator more powerful than the MLP. This means that the
complexity of MLP would be prohibitively large for some problems while SRN
could realize the desired mapping with acceptable computational constraints.
The speed of training of complex recurrent networks is crucial to their
successful application. Present work improves the previous results by training
the network with extended Kalman filter (EKF). We implemented a generic
Cellular SRN and applied it for solving two challenging problems: 2D maze
navigation and a subset of the connectedness problem. The speed of convergence
has been improved by several orders of magnitude in comparison with the earlier
results in the case of maze navigation, and superior generalization has been
demonstrated in the case of connectedness. The implications of this
improvements are discussed.

710.4184 | Critical charge dynamics of superconducting LSCO thin films probed by
complex microwave spectroscopy: Anomalous changes of the universality class
by hole doping | We study the critical charge dynamics of the superconducting to the
normal-state transition for LSCO thin films with a wide range of the Sr
concentration, by measuring the frequency-dependent excess parts of the complex
microwave conductivity, which is induced by the superconducting fluctuations.
We present a dynamic scaling analysis of the complex fluctuation conductivity,
which includes the information on the universality class and the dimensionality
of the critical charge dynamics as a function of the Sr concentration, the film
thickness and the magnetic field. In our previous study (H. Kitano et al.,
Phys. Rev. B 73, 092504 (2006).), the 2D-XY critical dynamics for underdoped
LSCO and the 3D-XY critical dynamics for optimally doped LSCO were reported. In
this study, we observed a novel two-dimensional unknown critical charge
dynamics for overdoped thin films from x=0.17 to 0.20, which is clearly
distinguished from the 2D-XY critical dynamics. Through the systematic
measurements by changing the film thickness or by applying small magnetic
field, it was confirmed that this unusual behavior, which is referred as 2D-"U"
below, was not induced by the finite size effect but was intrinsic to the
overdoped LSCO. Thus, it was found that the critical behavior in the phase
diagram of LSCO is classified into the following three types; (i) 2D-XY for
underdoped region, (ii) 3D-XY for optimally doped region, and (iii) 2D-"U" for
overdoped region. In other words, the dimensionality in the critical charge
dynamics is changed twice with hole doping. We discuss possible origins of such
anomalous dimensional crossovers with hole doping, including an interpretation
based on the possible existence of a hidden quantum critical point near the
optimally doped region.

710.4185 | Baryonium, tetra-quark state and glue-ball in large N_c QCD | From the large-N_c QCD point of view, baryonia, tetra-quark states, hybrids,
and glueballs are studied. The existence of these states is argued for. They
are constructed from baryons. In N_f=1 large N_c QCD, a baryonium is always
identical to a glueball with N_c valence gluons. The ground state 0^{-+}
glueball has a mass about 2450 MeV. f_0(1710) is identified as the lowest
0^{++} glueball. The lowest four-quark nonet should be f_0(1370), a_0(1450),
K^*_0(1430) and f_0(1500). Combining with the heavy quark effective theory,
spectra of heavy baryonia and heavy tetra-quark states are predicted. 1/N_c
corrections are discussed.

710.4186 | Reflection of microwave from energy deposit by X-ray irradiation in rock
salt: Implication of an ultra high energy salt neutrino detector to act like
a radio bubble chamber | Existence of GZK neutrinos (ultra high energy neutrinos) have been justified
although the flux is very low. A new method is desired to use a huge mass of a
detector medium to detect them. A fundamental study of radar method was carried
out to measure microwave reflection from electromagnetic energy deposit by
X-ray irradiation in a small rock salt sample. The reflection rate of 1x10^-6
was found at the energy deposit of 1x10^19 eV which was proportional to square
of the X-ray intensity suggesting the effect to be coherent scattering. The
decay time of the reflection was several seconds. This effect implies a large

710.4187 | Universal coding for correlated sources with complementary delivery | This paper deals with a universal coding problem for a certain kind of
multiterminal source coding system that we call the complementary delivery
coding system. In this system, messages from two correlated sources are jointly
encoded, and each decoder has access to one of the two messages to enable it to
reproduce the other message. Both fixed-to-fixed length and fixed-to-variable
length lossless coding schemes are considered. Explicit constructions of
universal codes and bounds of the error probabilities are clarified via
type-theoretical and graph-theoretical analyses. [[Keywords]] multiterminal

710.4189 | Structural relaxation around substitutional Cr3+ in pyrope garnet | The structural environment of substitutional Cr3+ ion in a natural pyrope
Mg3Al2Si3O12 has been investigated by Cr K-edge Extended X-ray Absorption Fine
Structure (EXAFS) and X-ray Absorption Near Edge Structure (XANES) coupled with
first-principles computations. The Cr-O distance is close to that in
knorringite Mg3Cr2Si3O12, indicating a full relaxation of the first neighbors.
The local C3i symmetry of the octahedral Y site is retained during Cr-Al
substitution. The second and third shells of neighbors (Mg and Si) relax only
partially. Site relaxation is accommodated by strain-induced bond buckling,

710.419 | Parameter estimation of ODE's via nonparametric estimators | Ordinary differential equations (ODE's) are widespread models in physics,
chemistry and biology. In particular, this mathematical formalism is used for
describing the evolution of complex systems and it might consist of
high-dimensional sets of coupled nonlinear differential equations. In this
setting, we propose a general method for estimating the parameters indexing
ODE's from times series. Our method is able to alleviate the computational
difficulties encountered by the classical parametric methods. These
difficulties are due to the implicit definition of the model. We propose the
use of a nonparametric estimator of regression functions as a first-step in the
construction of an M-estimator, and we show the consistency of the derived
estimator under general conditions. In the case of spline estimators, we prove
asymptotic normality, and that the rate of convergence is the usual
$\sqrt{n}$-rate for parametric estimators. Some perspectives of refinements of
this new family of parametric estimators are given.

710.4191 | Anisotropic Magnification Distortion of the 3D Galaxy Correlation: II.
Fourier and Redshift Space | In paper I of this series we discuss how magnification bias distorts the 3D
correlation function by enhancing the observed correlation in the line-of-sight
(LOS) orientation, especially on large scales. This lensing anisotropy is
distinctive, making it possible to separately measure the galaxy-galaxy,
galaxy-magnification {\it and} magnification-magnification correlations. Here
we extend the discussion to the power spectrum and also to redshift space. In
real space, pairs oriented close to the LOS direction are not protected against
nonlinearity even if the pair separation is large; this is because nonlinear
fluctuations can enter through gravitational lensing at a small transverse
separation (or i.e. impact parameter). The situation in Fourier space is
different: by focusing on a small wavenumber $k$, as is usually done, linearity
is guaranteed because both the LOS and transverse wavenumbers must be small.
This is why magnification distortion of the galaxy correlation appears less
severe in Fourier space. Nonetheless, the effect is non-negligible, especially
for the transverse Fourier modes, and should be taken into account in
interpreting precision measurements of the galaxy power spectrum, for instance
those that focus on the baryon oscillations. The lensing induced anisotropy of
the power spectrum has a shape that is distinct from the more well known
redshift space anisotropies due to peculiar motions and the Alcock-Paczynski
effect. The lensing anisotropy is highly localized in Fourier space while
redshift space distortions are more spread out. This means that one could
separate the magnification bias component in real observations, implying that
potentially it is possible to perform a gravitational lensing measurement
without measuring galaxy shapes.

N=6-16 on a proton target for wide range of incident energies, putting an
emphasis on the difference from the case of a carbon target. The analysis
includes the reaction cross sections of ^{19,20,22}C at 40 AMeV, the data of
which have recently been measured at RIKEN. The Glauber theory is used to
calculate the reaction cross sections. To describe the intrinsic structure of
the carbon isotopes, we use a Slater determinant generated from a
phenomenological mean-field potential, and construct the density distributions.
To go beyond the simple mean-field model, we adopt two types of dynamical
models: One is a core+n model for odd-neutron nuclei, and the other is a
core+n+n model for 16C and 22C. We propose empirical formulas which are useful
in predicting unknown cross sections.

710.4194 | On the Hodge-Newton filtration for p-divisible O-modules | The notions Hodge-Newton decomposition and Hodge-Newton filtration for
F-crystals are due to Katz and generalize Messing's result on the existence of
the local-\'etale filtration for p-divisible groups. Recently, some of Katz's
classical results have been generalized by Kottwitz to the context of
F-crystals with additional structures and by Moonen to $\mu$-ordinary
p-divisible groups. In this paper, we discuss further generalizations to the

710.4196 | Magnitude Uncertainties Impact Seismic Rate Estimates, Forecasts and
Predictability Experiments | The Collaboratory for the Study of Earthquake Predictability (CSEP) aims to
prospectively test time-dependent earthquake probability forecasts on their
consistency with observations. To compete, time-dependent seismicity models are
calibrated on earthquake catalog data. But catalogs contain much observational
uncertainty. We study the impact of magnitude uncertainties on rate estimates
in clustering models, on their forecasts and on their evaluation by CSEP's
consistency tests. First, we quantify magnitude uncertainties. We find that
magnitude uncertainty is more heavy-tailed than a Gaussian, such as a
double-sided exponential distribution, with scale parameter nu_c=0.1 - 0.3.
Second, we study the impact of such noise on the forecasts of a simple
clustering model which captures the main ingredients of popular short term
models. We prove that the deviations of noisy forecasts from an exact forecast
are power law distributed in the tail with exponent alpha=1/(a*nu_c), where a
is the exponent of the productivity law of aftershocks. We further prove that
the typical scale of the fluctuations remains sensitively dependent on the
specific catalog. Third, we study how noisy forecasts are evaluated in CSEP
consistency tests. Noisy forecasts are rejected more frequently than expected
for a given confidence limit. The Poisson assumption of the consistency tests
is inadequate for short-term forecast evaluations. To capture the
idiosyncrasies of each model together with any propagating uncertainties, the
forecasts need to specify the entire likelihood distribution of seismic rates.

as a Local Order Parameter | We characterize several phases of gapped spin systems by local order
parameters defined by quantized Berry phases. This characterization is
topologically stable against any small perturbation as long as the energy gap
remains finite. The models we pick up are $S=1,2$ dimerized Heisenberg chains
and S=2 Heisenberg chains with uniaxial single-ion-type anisotropy.
Analytically we also evaluate the topological local order parameters for the
generalized Affleck-Kennedy-Lieb-Tasaki (AKLT) model. The relation between the
present Berry phases and the fractionalization in the integer spin chains are
discussed as well.

710.4199 | Observation of Orbitally Excited B_s Mesons | We report the first observation of two narrow resonances consistent with
states of orbitally excited (L=1) B_s mesons using 1 fb^{-1} of ppbar
collisions at sqrt{s} = 1.96 TeV collected with the CDF II detector at the
Fermilab Tevatron. We use two-body decays into K^- and B^+ mesons reconstructed
as B^+ \to J/\psi K^+, J/\psi \to \mu^+ \mu^- or B^+ \to \bar{D}^0 \pi^+,

710.4202 | Sub-millimeter Observations of Giant Molecular Clouds in the Large
Magellanic Cloud: Temperature and Density as Determined from J=3-2 and J=1-0
transitions of CO | We have carried out sub-mm 12CO(J=3-2) observations of 6 giant molecular
clouds (GMCs) in the Large Magellanic Cloud (LMC) with the ASTE 10m sub-mm
telescope at a spatial resolution of 5 pc and very high sensitivity. We have
identified 32 molecular clumps in the GMCs and revealed significant details of
the warm and dense molecular gas with n(H2) $\sim$ 10$^{3-5}$ cm$^{-3}$ and
Tkin $\sim$ 60 K. These data are combined with 12CO(J=1-0) and 13CO(J=1-0)
results and compared with LVG calculations. We found that the ratio of
12CO(J=3-2) to 12CO(J=1-0) emission is sensitive to and is well correlated with
the local Halpha flux. We interpret that differences of clump propeties
represent an evolutionary sequence of GMCs in terms of density increase leading
to star formation.Type I and II GMCs (starless GMCs and GMCs with HII regions
only, respectively) are at the young phase of star formation where density does
not yet become high enough to show active star formation and Type III GMCs
(GMCs with HII regions and young star clusters) represents the later phase
where the average density is increased and the GMCs are forming massive stars.
The high kinetic temperature correlated with \Halpha flux suggests that FUV
heating is dominant in the molecular gas of the LMC.

regions only respectively are at the young phase of star formation where density does not yet become high enough to show active star formation and type iii gmcs gmcs with hii regions and young star clusters represents the later phase where the average density is increased and the gmcs are forming massive stars the high kinetic temperature correlated with halpha flux suggests that fuv heating is

The centrality dependence of identified particles in the triggered particle
cones is also presented. Particle yields and ratios are extracted on the
near-side and away-side of the trigger particle. The associate-particle ratios
are studied as a function of the angle relative to the trigger particle azimuth
$\Delta\phi$. Such studies should help elucidate the origin of the
modifications in the jet like correlations observed in Au+Au collisions
relative to p+p collisions. And these studies also will help understand the
variation of local parton densities at the away side. We discuss how these
measurements might be related to several scenarios for interactions of fast
partons with the medium created in Au+Au collision.

710.4204 | Chirality sensitive effect on surface states in chiral p-wave
superconductors | We study the local density of states at the surface of a chiral p-wave
superconductor in the presence of a weak magnetic field. As a result, the
formation of low-energy Andreev bound states is either suppressed or enhanced
by an applied magnetic field, depending on its orientation with respect to the
chirality of the p-wave superconductor. Similarly, an Abrikosov vortex, which
is situated not too far from the surface, leads to a zero-energy peak of the
density of states, if its chirality is the same as that of the superconductor,
and to a gap structure for the opposite case. We explain the underlying

710.4205 | Factorization Approach for Top Mass Reconstruction at High Energies | Using effective theories for jets and heavy quarks it is possible to prove
that the double differential top-antitop invariant mass distribution for the
process $e^+e^-\to t\bar t$ in the resonance region for c.m. energies $Q$ much
larger than the top mass can factorized into perturbatively computable hard
coefficients and jet functions and a non-perturbative soft function. For
invariant mass prescriptions based on hemispheres defined with respect to the
thrust axis the soft function can be extracted from massless jet event shape
distributions. This approach allows in principle for top mass determinations
without uncertainties from hadronization using the reconstruction method and to
quantify the top mass scheme dependence of the measured top quark mass value.

710.4206 | Measurement of 25Mg(p; gamma)26Al resonance strengths via gamma
spectrometry | The COMPTEL instrument performed the first mapping of the 1.809 MeV photons
in the Galaxy, triggering considerable interest in determing the sources of
interstellar 26Al. The predicted 26Al is too low compared to the observation,
for a better understanding more accurate rates for the 25Mg(p; gamma)26Al
reaction are required. The 25Mg(p;gamma)26Al reaction has been investigated at
the resonances at Er= 745; 418; 374; 304 keV at Ruhr-Universitat-Bochum using a
Tandem accelerator and a 4piNaI detector. In addition the resonance at Er = 189
keV has been measured deep underground laboratory at Laboratori Nazionali del
Gran Sasso, exploiting the strong suppression of cosmic background. This low

710.4207 | Low degree bounded cohomology and l^2-invariants for negatively curved
groups | We study the subgroup structure of discrete groups which share cohomological
properties which resemble non-negative curvature. Examples include all Gromov
hyperbolic groups.
We provide strong restrictions on the possible s-normal subgroups of a Gromov
hyperbolic group, or more generally a 'negatively curved' group. Another result
says that the image of a group, which is boundedly generated by a finite set of
amenable subgroups, in a Gromov hyperbolic group has to be virtually cyclic.
Moreover, we show that any homomorphic image of an analogue of a higher rank
lattices in a Gromov hyperbolic group must be finite. These results extend to a
certain class of randomorphisms in the sense of Monod. We study the class of
groups which admit proper quasi-1-cocycles and show that it is closed under
l2-orbit equivalence.

710.4208 | Structure factor of Bose-condensed systems | The structure factor for a Bose system with Bose-Einstein condensate is
considered in the frame of the self-consistent mean-field approximation. The
accomplished analysis demonstrates the principal importance of the following
three points: the necessity of preserving the approximation order, the
necessity of taking into account anomalous averages, and the necessity of gauge
symmetry breaking. If any one of these necessary conditions is not satisfied,
calculations yield the appearance of unphysical divergences of the structure

710.421 | Conductance of a tunnel point-contact of noble metals in the presence of
a single defect | In paper [1] (Avotina et al. Phys. Rev. B,74, 085411 (2006)) the effect of
Fermi surface anisotropy to the conductance of a tunnel point contact, in the
vicinity of which a single point-like defect is situated, has been investigated
theoretically. The oscillatory dependence of the conductance on the distance
between the contact and the defect has been found for a general Fermi surface
geometry. In this paper we apply the method developed in [1] to the calculation
of the conductance of noble metal contacts. An original algorithm, which
enables the computation of the conductance for any parametrically given Fermi
surface, is proposed. On this basis a pattern of the conductance oscillations,
which can be observed by the method of scanning tunneling microscopy, is
obtained for different orientations of the surface for the noble metals.

710.4213 | On the Integrable Structure of the Ising Model | Starting from the lattice $A_3$ realization of the Ising model defined on a
strip with integrable boundary conditions, the exact spectrum (including
excited states) of all the local integrals of motion is derived in the
continuum limit by means of TBA techniques. It is also possible to follow the
massive flow of this spectrum between the UV $c=1/2$ conformal fixed point and
the massive IR theory. The UV expression of the eigenstates of such integrals
of motion in terms of Virasoro modes is found to have only rational
coefficients and their fermionic representation turns out to be simply related
to the quantum numbers describing the spectrum.

710.4214 | Typicality for Generalized Microcanonical Ensembles | For a macroscopic, isolated quantum system in an unknown pure state, the
expectation value of any given observable is shown to hardly deviate from the
ensemble average with extremely high probability under generic equilibrium and
nonequilibrium conditions. Special care is devoted to the uncontrollable
microscopic details of the system state. For a subsystem weakly coupled to a
large heat bath, the canonical ensemble is recovered under much more general

710.4215 | On Majorana fermions on the lattice | The construction of massless Majorana fermions with chiral Yukawa couplings
on the lattice is considered. We find topological obstructions tightly linked
to those underlying the Nielsen-Ninomiya no-go theorem. In contradistinction to
chiral fermions the obstructions originate only from the combination of the
Dirac action and the Yukawa term. These findings are used to construct a
chirally invariant lattice action. We also show that the path intgral of this
theory is given by the Pfaffian of the corresponding Dirac operator.

710.4217 | Optimal rate of convergence for nonparametric change-point estimators
for nonstationary sequences | Let $(X_i)_{i=1,...,n}$ be a possibly nonstationary sequence such that
$\mathscr{L}(X_i)=P_n$ if $i\leq n\theta$ and $\mathscr{L}(X_i)=Q_n$ if
$i>n\theta$, where $0<\theta <1$ is the location of the change-point to be
estimated. We construct a class of estimators based on the empirical measures
and a seminorm on the space of measures defined through a family of functions
$\mathcal{F}$. We prove the consistency of the estimator and give rates of
convergence under very general conditions. In particular, the $1/n$ rate is
achieved for a wide class of processes including long-range dependent sequences
and even nonstationary ones. The approach unifies, generalizes and improves on
the existing results for both parametric and nonparametric change-point

710.4218 | Foldy-Wouthyusen Transformation and Semiclassical Limit for Relativistic
Particles in Strong External Fields | A general method of the Foldy-Wouthyusen (FW) transformation for relativistic
particles of arbitrary spin in strong external fields has been developed. The
use of the found transformation operator is not restricted by any definite
commutation relations between even and odd operators. The final FW Hamiltonian
can be expanded into a power series in the Planck constant which characterizes
the order of magnitude of quantum corrections. Exact expressions for low-order
terms in the Planck constant can be derived. Finding these expressions allows
to perform a simple transition to the semiclassical approximation which defines
a classical limit of the relativistic quantum mechanics. As an example,
interactions of spin-1/2 and scalar particles with a strong electromagnetic
field have been considered. Quantum and semiclassical equations of motion of
particles and their spins have been deduced. Full agreement between quantum and
classical theories has been established.

damping the different models agree. Compared to free space optical lattices,
quantum uncertainties of the potential and the possibility of atom-field
entanglement lead to modified phase transition characteristics, the appearance
of new phases or even quantum superpositions of different phases. Using a
corresponding effective master equation, which can be numerically solved for
few particles, we can study time evolution including dissipation. As an example
we exhibit the microscopic processes behind the transition dynamics from a Mott
insulator like state to a self-ordered superradiant state of the atoms, which
appears as steady state for transverse atomic pumping.

710.4223 | Time Scaling of Chaotic Systems: Application to Secure Communications | The paper deals with time-scaling transformations of dynamical systems. Such
scaling functions operate a change of coordinates on the time axis of the
system trajectories preserving its phase portrait. Exploiting this property, a
chaos encryption technique to transmit a binary signal through an analog
channel is proposed. The scheme is based on a suitable time-scaling function
which plays the role of a private key. The encoded transmitted signal is proved

710.4224 | Hecke operators on Hilbert-Siegel modular forms | We define Hilbert-Siegel modular forms and Hecke "operators" acting on them.
As with Hilbert modular forms, these linear transformations are not linear
operators until we consider a direct product of spaces of modular forms (with
varying groups), modulo natural identifications we can make between certain
spaces. With Hilbert-Siegel forms we identify several families of natural
identifications between certain spaces of modular forms. We associate the
Fourier coefficients of a form in our product space to even integral lattices,
independent of a basis and choice of coefficient rings. We then determine the
action of the Hecke operators on these Fourier coefficients, paralleling the
result of Hafner and Walling for Siegel modular forms (where the number field
is the field of rationals).

710.4226 | NGC3147: a "true" Seyfert 2 without the broad-line region | We report on simultaneous optical and X-ray observations of the Seyfert
galaxy, NGC3147. The XMM-Newton spectrum shows that the source is unabsorbed in
the X-rays ($N_H<5\times10^{20}$ cm$^{-2}$). On the other hand, no broad lines
are present in the optical spectrum. The origin of this optical/X-rays
misclassification (with respect to the Unification Model) cannot be attributed
to variability, since the observations in the two bands are simultaneous.
Moreover, a Compton-thick nature of the object can be rejected on the basis of
the low equivalent width of the iron K$\alpha$ line ($\simeq130$ eV) and the
large ratio between the 2-10 keV and the [OIII] fluxes. It seems therefore

710.4228 | Retrospective Markov chain Monte Carlo methods for Dirichlet process
hierarchical model | Inference for Dirichlet process hierarchical models is typically performed
using Markov chain Monte Carlo methods, which can be roughly categorised into
marginal and conditional methods. The former integrate out analytically the
infinite-dimensional component of the hierarchical model and sample from the
marginal distribution of the remaining variables using the Gibbs sampler.
Conditional methods impute the Dirichlet process and update it as a component
of the Gibbs sampler. Since this requires imputation of an infinite-dimensional
process, implementation of the conditional method has relied on finite
approximations. In this paper we show how to avoid such approximations by
designing two novel Markov chain Monte Carlo algorithms which sample from the
exact posterior distribution of quantities of interest. The approximations are
avoided by the new technique of retrospective sampling. We also show how the
algorithms can obtain samples from functionals of the Dirichlet process. The
marginal and the conditional methods are compared and a careful simulation

| stat.ME stat.CO | inference for dirichlet process hierarchical models is typically performed using markov chain monte carlo methods which can be roughly categorised into marginal and conditional methods the former integrate out analytically the infinitedimensional component of the hierarchical model and sample from the marginal distribution of the remaining variables using the gibbs sampler conditional methods impute the dirichlet process and update it as a component of the gibbs sampler since this requires imputation of an infinitedimensional process implementation of the conditional method has relied on finite approximations in this paper we show how to avoid such approximations by designing two novel markov chain monte carlo algorithms which sample from the exact posterior distribution of quantities of interest the approximations are avoided by the new technique of retrospective sampling we also show how the algorithms can obtain samples from functionals of the dirichlet process the marginal and the conditional methods are compared and a careful simulation study is included which involves a nonconjugate model different datasets and prior specifications | [['inference', 'for', 'dirichlet', 'process', 'hierarchical', 'models', 'is', 'typically', 'performed', 'using', 'markov', 'chain', 'monte', 'carlo', 'methods', 'which', 'can', 'be', 'roughly', 'categorised', 'into', 'marginal', 'and', 'conditional', 'methods', 'the', 'former', 'integrate', 'out', 'analytically', 'the', 'infinitedimensional', 'component', 'of', 'the', 'hierarchical', 'model', 'and', 'sample', 'from', 'the', 'marginal', 'distribution', 'of', 'the', 'remaining', 'variables', 'using', 'the', 'gibbs', 'sampler', 'conditional', 'methods', 'impute', 'the', 'dirichlet', 'process', 'and', 'update', 'it', 'as', 'a', 'component', 'of', 'the', 'gibbs', 'sampler', 'since', 'this', 'requires', 'imputation', 'of', 'an', 'infinitedimensional', 'process', 'implementation', 'of', 'the', 'conditional', 'method', 'has', 'relied', 'on', 'finite', 'approximations', 'in', 'this', 'paper', 'we', 'show', 'how', 'to', 'avoid', 'such', 'approximations', 'by', 'designing', 'two', 'novel', 'markov', 'chain', 'monte', 'carlo', 'algorithms', 'which', 'sample', 'from', 'the', 'exact', 'posterior', 'distribution', 'of', 'quantities', 'of', 'interest', 'the', 'approximations', 'are', 'avoided', 'by', 'the', 'new', 'technique', 'of', 'retrospective', 'sampling', 'we', 'also', 'show', 'how', 'the', 'algorithms', 'can', 'obtain', 'samples', 'from', 'functionals', 'of', 'the', 'dirichlet', 'process', 'the', 'marginal', 'and', 'the', 'conditional', 'methods', 'are', 'compared', 'and', 'a', 'careful', 'simulation', 'study', 'is', 'included', 'which', 'involves', 'a', 'nonconjugate', 'model', 'different', 'datasets', 'and', 'prior', 'specifications']] | [0.004612560327871737, 0.05882472897319092, -0.14555831536011074, 0.12169702826454395, -0.05779215474949634, -0.11547810070115669, 0.08915865510009252, 0.43912088805921823, -0.30153193093656777, -0.3105353367827336, 0.12683033053160095, -0.22376543115361605, -0.09909542136775128, 0.1785009982238288, -0.04066236031028521, 0.11676776434465996, 0.13474583031935056, -0.0073347650692764535, -0.08235043780429356, -0.2611464122562748, 0.29745338096266544, 0.0772940848241504, 0.3069845370903432, -0.07640351948373199, 0.1577611787788884, 0.025185952717662757, -0.05920747586340834, -0.02557227011006999, -0.13032022092620427, 0.1218633351886802, 0.2367988696124123, 0.1579613820789943, 0.33414298975952417, -0.4081839246850521, -0.22039440335952734, 0.15159744427768032, 0.1694985587410741, 0.11741266542274564, 0.021788834040866692, -0.3005196951576565, 0.02265595035425511, -0.20024084698139544, -0.03501799450738423, -0.1373218576008656, -0.11471801042466996, 0.04960250666193911, -0.33252888800666097, 0.10889840565873618, 0.08915501236298447, 0.044670906955802656, -0.007055182974920215, -0.18591880073479142, -0.014076829070214137, 0.07199171717076686, 0.07406025611330788, -0.025342312215053172, 0.11401805216839245, -0.08302854663827064, -0.16433236007971397, 0.2820541116532432, -0.01757311480995043, -0.25185215886098794, 0.16194191508427128, -0.06289222589637859, -0.19506758081176914, 0.13294203957565218, 0.17144722437222365, 0.17524739485079738, -0.21611224549138044, 0.1278792732508842, 0.0025356794947320707, 0.12329162984906909, -0.036193665901776854, -0.08222982193713627, 0.17152859911838747, 0.15785134956240654, 0.053981329892279516, 0.179209953103164, -0.11913760797771435, -0.18150735436097146, -0.2789281345006213, -0.1469052911235345, -0.24597882344780198, -0.010561244243879366, -0.13314210620644945, -0.2328963812429413, 0.35045408438442344, 0.23680905771831373, 0.1823906985206911, 0.09167116610768128, 0.30429509398246923, 0.14538642335108043, 0.017426803125999868, 0.07321421161338866, 0.10832045042988317, 0.1252866220009704, 0.01815972461208073, -0.16151818133405332, 0.1485696068490822, 0.0692327888570277] |
710.4229 | Robust non-adiabatic molecular dynamics for metals and insulators | We present a new formulation of the correlated electron-ion dynamics (CEID)
scheme, which systematically improves Ehrenfest dynamics by including quantum
fluctuations around the mean-field atomic trajectories. We show that the method
can simulate models of non-adiabatic electronic transitions, and test it
against exact integration of the time-dependent Schroedinger equation. Unlike
previous formulations of CEID, the accuracy of this scheme depends on a single
tunable parameter which sets the level of atomic fluctuations included. The
convergence to the exact dynamics by increasing the tunable parameter is
demonstrated for a model two level system. This algorithm provides a smooth
description of the non-adiabatic electronic transitions which satisfies the
kinematic constraints (energy and momentum conservation) and preserves quantum
coherence. The applicability of this algorithm to more complex atomic systems
is discussed.

710.423 | Trees, linear orders and G\^ateaux smooth norms | We introduce a linearly ordered set Z and use it to prove a necessity
condition for the existence of a G\^ateaux smooth norm on C(T), where T is a
tree. This criterion is directly analogous to the corresponding equivalent
condition for Fr\'echet smooth norms. In addition, we prove that if C(T) admits

710.4231 | Analyzing covert social network foundation behind terrorism disaster | This paper addresses a method to analyze the covert social network foundation
hidden behind the terrorism disaster. It is to solve a node discovery problem,
which means to discover a node, which functions relevantly in a social network,
but escaped from monitoring on the presence and mutual relationship of nodes.
The method aims at integrating the expert investigator's prior understanding,
insight on the terrorists' social network nature derived from the complex graph
theory, and computational data processing. The social network responsible for
the 9/11 attack in 2001 is used to execute simulation experiment to evaluate
the performance of the method.

710.4233 | Hamiltonian stationary Lagrangian tori contained in a hypersphere | The Clifford torus is a torus in a three-dimensional sphere. Homogeneous tori
are simple generalization of the Clifford torus which still in a
three-dimensional sphere. There is a way to construct tori in a
three-dimensional sphere using the Hopf fibration. In this paper, all
Hamiltonian stationary Lagrangian tori which is contained in a hypersphere in
the complex Euclidean plane are constructed explicitly. Then it is shown that
they are homogeneous tori. For the construction, flat quaternionic connections

joint posterior distribution of parameters and missing data in hierarchical
linear models with arbitrary symmetric error distributions. We show that the
convergence can be uniform, geometric or sub-geometric depending on the
relative tail behaviour of the error distributions, and on the parametrisation
chosen. Our theory is applied to characterise the convergence of the Gibbs
sampler on latent Gaussian process models. We indicate how the theoretical
framework we introduce will be useful in analyzing more complex models.

710.4235 | Top-Down Causation by Information Control: From a Philosophical Problem
to a Scientific Research Program | It has been claimed that different types of causes must be considered in
biological systems, including top-down as well as same-level and bottom-up
causation, thus enabling the top levels to be causally efficacious in their own
right. To clarify this issue, important distinctions between information and
signs are introduced here and the concepts of information control and
functional equivalence classes in those systems are rigorously defined and used
to characterise when top down causation by feedback control happens, in a way
that is testable. The causally significant elements we consider are equivalence
classes of lower level processes, realised in biological systems through
different operations having the same outcome within the context of information
control and networks.

with realistic quark masses. An improved scheme for the non-perturbative
renormalization of the Polyakov loop is used and we compare its temperature
dependence for QCD with different flavor content. We also analyze screening
masses extracted from singlet free energies at various temperatures close to

710.4238 | Multi-line (sub)millimetre observations of the high-mass proto cluster
IRAS 05358+3543 | Since most high- and intermediate-mass protostars are at great distance and
form in clusters, high linear resolution observations are needed to investigate
their physical properties. To study the gas in the innermost region around the
protostars in the proto-cluster IRAS 05358+3543, we observed the source in
several transitions of methanol and other molecular species with the Plateau de
Bure Interferometer and the Submillimeter Array, reaching a linear resolution
of 1100 AU. We determine the kinetic temperature of the gas around the
protostars through an LVG and LTE analysis of their molecular emission; the
column densities of CH3OH, CH3CN and SO2 are also derived. Constrains on the
density of the gas are estimated for two of the protostellar cores. We find
that the dust condensations are in various evolutionary stages. The powerhouse
of the cluster, mm1a, harbours a hot core with T~220 (75<T<330) K. A
double-peaked profile is detected in several transitions toward mm1a, and we
found a velocity gradient along a linear structure which could be perpendicular
to one of the outflows from the vicinity of mm1a. Since the size of the
double-peaked emission is less than 1100 AU, we suggest that mm1a might host a
massive circumstellar disk. The other sources are in earlier stages of star
formation. The least active source, mm3, could be a starless massive core,
since it is cold (T<20 K), with a large reservoir of accreting material (M ~ 19
M_\odot), but no molecular emission peaks on it.

710.4241 | BCS-BEC crossover of neutron pairs in symmetric and asymmetric nuclear
matter | We propose new types of density dependent contact pairing interaction which
reproduce the pairing gaps in symmetric and neutron matter obtained by a
microscopic treatment based on the nucleon-nucleon interaction. These
interactions are able to simulate the pairing gaps of either the bare
interaction or the interaction screened by the medium polarization effects. It
is shown that the medium polarization effects cannot be cast into the density
power law function usually introduced together with the contact interaction and
require the introduction of another isoscalar term. The BCS-BEC crossover of
neutrons pairs in symmetric and symmetric nuclear matter is studied by using
these contact interactions. It is shown that the bare and screened pairing
interactions lead to different features of the BCS-BEC crossover in symmetric
nuclear matter. For the screened pairing interaction, a two-neutron BEC state
is formed in symmetric matter at $k_{Fn}\sim 0.2$ fm$^{-1}$ (neutron density

the benefit of a novel Rao-Blackwellisation device which can be easily

so-called Fresnel field terms in the radiation integrals. We assume a ``full
phase'' system with reference receiver to provide the reference phase. We
describe in some detail the hardware and software implementation of the system
used for the holographic measurement of the 12m ALMA prototype submillimeter
antennas. We include a description of the practicalities of a measurement and
surface setting. The results for both the VertexRSI and AEC

variety of observation schemes, including diffusion observed with error,
observation of a subset of the components of the multivariate diffusion and
arrival times of a Poisson process whose intensity is a known function of the
diffusion (Cox process). Unlike currently available methods, our particle
filters do not require approximations of the transition and/or the observation

for the exact simulation of the diffusion process and the unbiased estimation
of the transition density as described in \cite{besk:papa:robe:fear:2006}. %In

the Poisson Estimator of \cite{besk:papa:robe:fear:2006}. %Thus, our filters

710.4246 | Critical properties of the four-state Commutative Random Permutation
Glassy Potts model in three and four dimensions | We investigate the critical properties of the four-state commutative random
permutation glassy Potts model in three and four dimensions by means of Monte
Carlo simulation and of a finite size scaling analysis. Thanks to the use of a
field programmable gate array we have been able to thermalize a large number of
samples of systems with large volume. This has allowed us to observe a
spin-glass ordered phase in d=4 and to study the critical properties of the
transition. In d=3, our results are consistent with the presence of a

710.4248 | INTEGRAL - operating high-energy detectors for five years in space | The INTEGRAL satellite, which studies the Universe in the hard X-ray and soft
Gamma-ray domain, has been operational for 5 years now. The X-ray telescopes,
which use the coded mask technique, provide unprecedented spectral and imaging
resolution. This led to a number of discoveries, such as the distribution of
diffuse emission in the Galaxy, the discovery of highly absorbed sources and
fast X-ray transients in the Galactic Plane, localization of ~50 Gamma-ray
bursts, and the resolution of the cosmic X-ray background around its peak at 30
keV. About 300 previously known X-ray sources have been detected and in
addition more than 200 new sources have been discovered. INTEGRAL provides
spectra starting at 3 keV and ranging up to several hundred keV. This article
gives a brief overview about the major discoveries of INTEGRAL.

710.4249 | Complex Kerr Geometry, Twistors and the Dirac Electron | The Kerr-Newman spinning particle displays some remarkable relations to the
Dirac electron and has a reach spinor structure which is based on a twistorial
description of the Kerr congruence determined by the Kerr theorem. We consider
the relation between this spinor-twistorial structure and spinors of the Dirac
equation, and show that the Dirac equation may naturally be incorporated into
Kerr-Schild formalism as a master equation controlling the twistorial structure
of Kerr geometry. As a result, the Dirac electron acquires an extended
space-time structure having clear coordinate description with natural
incorporation of a gravitational field. The relation between the Dirac wave
function and Kerr geometry is realized via a chain of links: {\it Dirac wave
function $ \Rightarrow $ Complex Kerr-Newman Source $ \Rightarrow $ Kerr
Theorem $ \Rightarrow $ Real Kerr geometry.} As a result, the wave function

710.4252 | Scattering of Long-Wavelength Gravitational Waves | We consider the scattering of a low-frequency gravitational wave by a massive
compact body in vacuum. We apply partial-wave methods to compute amplitudes for
the helicity-conserving and helicity-reversing contributions to the cross
section, accurate to first order in $M\omega$. Contrary to previous claims, we
find that the partial-wave cross section agrees with the cross section derived
via perturbation-theory methods.
| gr-qc astro-ph | we consider the scattering of a lowfrequency gravitational wave by a massive compact body in vacuum we apply partialwave methods to compute amplitudes for the helicityconserving and helicityreversing contributions to the cross section accurate to first order in momega contrary to previous claims we find that the partialwave cross section agrees with the cross section derived via perturbationtheory methods | [['we', 'consider', 'the', 'scattering', 'of', 'a', 'lowfrequency', 'gravitational', 'wave', 'by', 'a', 'massive', 'compact', 'body', 'in', 'vacuum', 'we', 'apply', 'partialwave', 'methods', 'to', 'compute', 'amplitudes', 'for', 'the', 'helicityconserving', 'and', 'helicityreversing', 'contributions', 'to', 'the', 'cross', 'section', 'accurate', 'to', 'first', 'order', 'in', 'momega', 'contrary', 'to', 'previous', 'claims', 'we', 'find', 'that', 'the', 'partialwave', 'cross', 'section', 'agrees', 'with', 'the', 'cross', 'section', 'derived', 'via', 'perturbationtheory', 'methods']] | [-0.11488676500699387, 0.06140435597827208, -0.0809184932952811, 0.09377532927640553, -0.06038594197738787, -0.0008310003141904699, 0.01435134105448579, 0.3521977004049153, -0.13838621736343565, -0.20165804640695068, -0.023460053658145, -0.32767040072137427, -0.1147037313223399, 0.22622590842817364, 0.0357756518341344, 0.09323757633181481, 0.08823971644220553, 0.06107618765712812, -0.09018239213137663, -0.19948873772077133, 0.39595357315807506, 0.02475806074377535, 0.22412694357977858, 0.11651602499829285, 0.06081273727889719, 0.0873899601544414, -0.08157322716353269, -0.013408184758034247, -0.17453130433029307, 0.1602810020397963, 0.28941470777198414, 0.04564070865383436, 0.08127145854563549, -0.44709563820526516, -0.16051631708276168, 0.049445263792535867, 0.12300088362977037, 0.17861801231729574, 0.04557366845808152, -0.2885870760114029, 0.07887163417462002, -0.23435658357780556, -0.16519859394636646, -0.08797907916796875, 0.05512025477043513, -0.044147679509980414, -0.2853171610241306, 0.09955295549047276, -0.029553973886730343, -0.07510789337664328, -0.06316832091723537, -0.1580715360569543, 0.013191539416860404, 0.03665173170959641, 0.1091956927597619, 0.03641799613351709, 0.13148196288063352, -0.09310290103392868, -0.1330132497522723, 0.3651604610294553, -0.1427611298879191, -0.19720885170430974, 0.11611532037355134, -0.20214110443464897, -0.1307748149927898, 0.22477855840055594, 0.20681936814096466, 0.1142181359910896, -0.14299376134696448, 0.0994366201208824, 0.034464289908194994, 0.17454909240317146, 0.1247852952420262, -0.036181620137509085, 0.13852910392371745, 0.11305256753132262, 0.007204541101537901, 0.06222532826861174, -0.14027972070596598, -0.04811947063767705, -0.35709609232586004, -0.10718342564083788, -0.08159938461452337, 0.05528901266169951, 0.005992447957647402, -0.13850778506683378, 0.2740426421936216, 0.15607129135329662, 0.256190897961115, 0.09888590639457107, 0.38216050932633466, 0.1702162387102425, 0.06707593836372011, 0.05480774179711167, 0.34527783526171896, 0.22409698155564095, 0.09783469965874121, -0.18314625139765697, -0.030177363925131744, 0.0684661674634393] |
