712.0679 | Asymptotic normality of the Quasi Maximum Likelihood Estimator for
multidimensional causal processes | Strong consistency and asymptotic normality of the Quasi-Maximum Likelihood
Estimator (QMLE) are given for a general class of multidimensional causal
processes. For particular cases already studied in the literature (for instance
univariate or multivariate GARCH, ARCH, ARMA-GARCH processes) the assumptions
required for establishing these results are often weaker than existing
conditions. The QMLE asymptotic behavior is also given for numerous new
examples of univariate or multivariate processes (for instance TARCH or NLARCH
processes).

712.068 | Stellar mass estimates in early-type galaxies from lensing+dynamical and
photometric measurements | In this paper we compare two different diagnostics for estimating stellar
masses in early-type galaxies and we establish their level of reliability. In
particular, we consider the well-studied sample of 15 field elliptical galaxies
selected from the Sloan Lens ACS (SLACS) Survey (z = 0.06-0.33). We examine
here the correlation between the stellar mass values, enclosed inside the
Einstein radius of each lens, based on analyses of lensing and stellar dynamics
combined and based on multiwavelength photometry spectral template fitting. The
lensing+dynamics stellar mass is obtained from the published SLACS Survey
results, assuming a two-component density distribution model and a prior from
the fundamental plane on the mass-to-light ratio for the lens galaxies. The
photometric stellar mass is measured by fitting the observed spectral energy
distribution of the galaxies (from the SDSS multi-band photometry over 354-913
nm) with composite stellar population templates, under the assumption that
light traces stellar mass. The two methods are completely independent. They
rely on several different assumptions, and so, in principle, both can have
significant biases. Based on our sample of massive galaxies, we find
consistency between the lensing+dynamics and the photometric mass estimates. We
obtain a Pearson linear correlation coefficient of 0.94 and a median value of
the ratio between the former and the latter mass measurements of 1.1+/-0.1.
This suggests that both methods can separately yield reliable stellar masses of
early-type galaxies, and confirms that photometric mass estimates are accurate,
as long as optical/near-IR rest frame photometry is available.

712.0682 | Tunable transmission via quantum state evolution in oval quantum dots | We explore the quantum transmission through open oval shaped quantum dots.
The transmission spectra show periodic resonances and, depending on the
geometry parameter, a strong suppression of the transmission for low energies.
Applying a weak perpendicular magnetic field changes this situation drastically
and introduces a large conductance. We identify the underlying mechanisms being
partially due to the specific shape of the oval that causes a systematic
decoupling of a substantial number of states from the leads. Importantly a
pairwise destructive interference of the transmitting states is encountered
thereby leading to the complete conductance suppression. Coupling properties
and interferences can be tuned via a weak magnetic field. These properties are
robust with respect to the presence of disorder in the quantum dot.

712.0684 | Compact embeddings of model subspaces of the Hardy space | We study embeddings of model (star-invariant) subspaces $K^p_{\Theta}$ of the
Hardy space $H^p$, associated with an inner function $\Theta$. We obtain a
criterion for the compactness of the embedding of $K^p_{\Theta}$ into
$L^p(\mu)$ analogous to the Volberg--Treil theorem on bounded embeddings and
answer a question posed by Cima and Matheson. The proof is based on Bernstein

712.0685 | From Discrete Space-Time to Minkowski Space: Basic Mechanisms, Methods
and Perspectives | This survey article reviews recent results on fermion system in discrete
space-time and corresponding systems in Minkowski space. After a basic
introduction to the discrete setting, we explain a mechanism of spontaneous
symmetry breaking which leads to the emergence of a discrete causal structure.
As methods to study the transition between discrete space-time and Minkowski
space, we describe a lattice model for a static and isotropic space-time,
outline the analysis of regularization tails of vacuum Dirac sea
configurations, and introduce a Lorentz invariant action for the masses of the
Dirac seas. We mention the method of the continuum limit, which allows to
analyze interacting systems. Open problems are discussed.

712.0686 | Violation of Rotational Invariance of Local Realistic Models with Two
Settings | We have considered a two-particle Bell experiment to visualize the conflict
between rotational invariance of physical laws and a specific local realistic
theory. The experiment is reproducible by using a local realistic theory
obtained in a two-setting Bell experiment. The generalized Bell inequality {[J.
Phys. A: Math. Theor. {\bf 40}, 13101 (2007)]}, which is derived under the
assumption that there exists a rotationally invariant local realistic theory,
turns out to disprove such a local realistic model existing with a two-setting
experiment. This implies that such a model is not rotationally invariant and
should, therefore, be ruled out in some situations.

712.0687 | Loop Quantization of Polarized Gowdy Model on $T^3$: Kinematical States
and Constraint Operators | In this second paper on loop quantization of Gowdy model, we introduce the
kinematical Hilbert space on which appropriate holonomies and fluxes are well
represented. The quantization of the volume operator and the Gauss constraint
is straightforward. Imposition of the Gauss constraint can be done on the
kinematical Hilbert space to select subspace of gauge invariant states. We
carry out the quantization of the Hamiltonian constraint making specific
choices. Alternative choices are briefly discussed. It appears that to get

712.0688 | Ergodic Theory, Abelian Groups, and Point Processes Induced by Stable
Random Fields | We consider a point process sequence induced by a stationary symmetric
alpha-stable (0 < alpha < 2) discrete parameter random field. It is easy to
prove, following the arguments in the one-dimensional case in Resnick and
Samorodnitsky (2004), that if the random field is generated by a dissipative
group action then the point process sequence converges weakly to a cluster
Poisson process. For the conservative case, no general result is known even in
the one-dimensional case. We look at a specific class of stable random fields
generated by conservative actions whose effective dimensions can be computed
using the structure theorem of finitely generated abelian groups. The
corresponding point processes sequence is not tight and hence needs to be
properly normalized in order to ensure weak convergence. This weak limit is
computed using extreme value theory and some counting techniques.

712.0689 | Introduction to AdS-CFT | These lectures present an introduction to AdS-CFT, and are intended both for
begining and more advanced graduate students, which are familiar with quantum
field theory and have a working knowledge of their basic methods. Familiarity
with supersymmetry, general relativity and string theory is helpful, but not
necessary, as the course intends to be as self-contained as possible. I will
introduce the needed elements of field and gauge theory, general relativity,
supersymmetry, supergravity, strings and conformal field theory. Then I
describe the basic AdS-CFT scenario, of ${\cal N}=4 $ Super Yang-Mills's
relation to string theory in $AdS_5\times S_5$, and applications that can be
derived from it: 3-point functions, quark-antiquark potential, finite
temperature and scattering processes, the pp wave correspondence and spin

712.069 | XMM-Newton observations of the Galactic globular clusters NGC 2808 and
NGC 4372 | Galactic globular clusters harbour binary systems that are detected as faint
X-ray sources. These close binaries are thought to play an important role in
the stability of the clusters by liberating energy and delaying the inevitable
core collapse of globular clusters. The inventory of close binaries and their
identification is therefore essential. We present XMM-Newton observations of
two Galactic globular clusters: NGC 2808 and NGC 4372. We use X-ray spectral
and variability analysis combined with ultra-violet observations made with the
XMM-Newton optical monitor and published data from the Hubble Space Telescope
to identify sources associated with the clusters. We compare the results of our
observations with estimates from population synthesis models. Five sources out
of 96 are likely to be related to NGC 2808. Nine sources are found in the field
of view of NGC 4372, none being located inside its half-mass radius. We find
one quiescent neutron star low mass X-ray binary candidate in the core of NGC
2808, and propose that the majority of the central sources in NGC 2808 are
cataclysmic variables. An estimation leads to ~20+/-10 cataclysmic variables
with luminosity above 4.25 x 10^31 erg s^-1. Millisecond pulsars could also be
present in the core of NGC 2808, and some sources outside of the half-mass
radius could possibly be linked to the cluster.

712.0691 | Iterative Methods for Model Reduction by Domain Decomposition | We propose a method to reduce the computational effort to solve a partial
differential equation on a given domain. The main idea is to split the domain
of interest in two subdomains, and to use different approximation methods in
each of the two subdomains. In particular, in one subdomain we discretize the
governing equations by a canonical scheme, whereas in the other one we solve a
reduced order model of the original problem. Different approaches to couple the
low-order model to the usual discretization are presented. The effectiveness of
these approaches is tested on numerical examples pertinent to non-linear model

| physics.class-ph | we propose a method to reduce the computational effort to solve a partial differential equation on a given domain the main idea is to split the domain of interest in two subdomains and to use different approximation methods in each of the two subdomains in particular in one subdomain we discretize the governing equations by a canonical scheme whereas in the other one we solve a reduced order model of the original problem different approaches to couple the loworder model to the usual discretization are presented the effectiveness of these approaches is tested on numerical examples pertinent to nonlinear model problems including the laplace equation with nonlinear boundary conditions and the compressible euler equations | [['we', 'propose', 'a', 'method', 'to', 'reduce', 'the', 'computational', 'effort', 'to', 'solve', 'a', 'partial', 'differential', 'equation', 'on', 'a', 'given', 'domain', 'the', 'main', 'idea', 'is', 'to', 'split', 'the', 'domain', 'of', 'interest', 'in', 'two', 'subdomains', 'and', 'to', 'use', 'different', 'approximation', 'methods', 'in', 'each', 'of', 'the', 'two', 'subdomains', 'in', 'particular', 'in', 'one', 'subdomain', 'we', 'discretize', 'the', 'governing', 'equations', 'by', 'a', 'canonical', 'scheme', 'whereas', 'in', 'the', 'other', 'one', 'we', 'solve', 'a', 'reduced', 'order', 'model', 'of', 'the', 'original', 'problem', 'different', 'approaches', 'to', 'couple', 'the', 'loworder', 'model', 'to', 'the', 'usual', 'discretization', 'are', 'presented', 'the', 'effectiveness', 'of', 'these', 'approaches', 'is', 'tested', 'on', 'numerical', 'examples', 'pertinent', 'to', 'nonlinear', 'model', 'problems', 'including', 'the', 'laplace', 'equation', 'with', 'nonlinear', 'boundary', 'conditions', 'and', 'the', 'compressible', 'euler', 'equations']] | [-0.08102341804228592, 0.005028830310166405, -0.0697096533697556, 0.034462864149214796, -0.11764377830836006, -0.13542613384248525, -0.020974833928783864, 0.31990737386309265, -0.3227242507988162, -0.28634393716786516, 0.12505334351322075, -0.2656025958243398, -0.12969408523732504, 0.1833591172900541, -0.060956457580782865, 0.11399829623763237, 0.06670580289669727, 0.0032076767090250527, -0.10833592269275534, -0.2659698819277988, 0.35805592554408994, -0.07917378605915266, 0.2656258564981583, 0.012799257664275438, 0.16219931227367437, -0.08518818654773529, -0.046056736456720454, 0.03168179535944211, -0.13747074807740814, 0.13588873257047676, 0.2531334868869172, 0.07459049568544224, 0.34149406386310593, -0.4728635866848523, -0.22958208118941179, 0.06079669119310239, 0.13337766658923214, 0.13725446005915537, 0.01858565072108289, -0.2624936640475011, 0.08390152851605212, -0.11308181834439829, -0.13715524706384985, -0.052292020983275095, -0.04807377259426734, 0.02095773228721922, -0.2774062392612298, 0.06251307049962251, 0.03920325440387323, -0.03474705550501025, -0.10775985898809474, -0.11581194926085964, 0.021730517069890834, 0.08836323448268925, 0.05499844434936613, -0.01798120741078859, 0.033879256476403066, -0.11373571113666944, -0.09731183340160274, 0.4202740102548871, -0.046671137194304414, -0.36226221330856023, 0.20374155635210245, -0.09088896381211255, -0.10318731379352118, 0.11909745846009046, 0.21954865704531568, 0.16201544116790356, -0.13643663046930574, 0.08844158321663965, -0.01828671245031026, 0.1466540199359307, 0.03749613585195651, -0.0765349548024109, 0.07075878204941227, 0.17851637872375073, 0.0852773076111222, 0.13720238046861546, -0.03656140537401498, -0.1704790155442121, -0.31442245364642557, -0.14242170537870966, -0.16519522916100787, -0.03958835339239031, -0.08632349291420133, -0.16386697308993653, 0.42488599853628295, 0.19465884500951097, 0.16033147707818435, 0.003815280543150086, 0.34148362672708016, 0.18071262804758653, 0.03476926472636446, 0.0493489505330983, 0.17078300246053882, 0.14698603228061347, 0.11335414982188427, -0.2707572914741672, -0.0076913824264090835, 0.16352426877506732] |

712.0694 | Compact embedded hypersurfaces with constant higher order anisotropic
mean curvatures | Given a positive function $F$ on $S^n$ which satisfies a convexity condition,
for $1\leq r\leq n$, we define the $r$-th anisotropic mean curvature function
$H^F_r$ for hypersurfaces in $\mathbb{R}^{n+1}$ which is a generalization of
the usual $r$-th mean curvature function. We prove that a compact embedded
hypersurface without boundary in $\R^{n+1}$ with $H^F_r={constant}$ is the
Wulff shape, up to translations and homotheties. In case $r=1$, our result is

712.0695 | Ionization of the hydrogen atom by intense ultrashort laser pulses | The ionization of atomic hydrogen in intense laser fields is studied
theoretically. The calculations were performed applying both quantummechanical
and classical approaches. Treating the problem quantummechanically, the time
dependent Schr\"odinger equation (TDSE) of our system was first transformed
into a pseudo-momentum space and solved in this space iteratively. While
neglecting the Coulomb potential during the solution of the TDSE we got the
results in the Volkov approximation, in the first order solution we taken into
account the Coulomb potential as perturbation. The classical calculations were
performed within the framework of the classical trajectory Monte-Carlo (CTMC)
method.
The double differential ionization probabilities are calculated for different
laser pulses and a reasonable agreement was found between the theories. Major
differences can be observed in the angular distribution of electrons at low
electron energies between classical and the quantummechanical approaches. At
high electron energies the differences disappear, which indicates that the
generation of low energy electrons is of quantum type, and it is strongly
influenced by the Coulomb potential, while the production of high energy
electrons is of classical type and it is less influenced by the Coulomb
interaction. Our results are also compared with the Coulomb-Volkov (CV) model
calculations.

712.0696 | The T Tauri star RY Tau as a case study of the inner regions of
circumstellar dust disks | We study the inner region of the circumstellar disk around the TTauri star RY
Tau. Our aim is to find a physical description satisfying the available
interferometric data, obtained with the mid-infrared interferometric instrument
at the Very Large Telescope Interferometer, as well as the spectral energy
distribution. We also compare the findings with the results of similar studies,
including those of intermediate-mass stars. Our analysis is done within the
framework of a passive circumstellar disk, which is optionally supplemented by
the effects of accretion and an added envelope. To achieve a more consistent
and realistic model, we used our continuum transfer code MC3D. In addition, we
studied the shape of the 10um silicate emission feature in terms of the
underlying dust population, both for single-dish and for interferometric
measurements. We show that a modestly flaring disk model with accretion can
explain both the observed spectral energy distribution and the mid-infrared
visibilities obtained with the mid-infrared infrared instrument. We found an
interesting ambiguity: a circumstellar active disk model with an added
envelope, and a lower accretion rate than in the active disk model without
envelope, could represent the observations equally as well. This type of model
with the envelope should be considered a viable alternative in future models of
other TTauri stars. The approach of a disk with a puffed-up inner rim wall and
the influence of a stellar companion is also discussed. From the study of the
silicate emission feature we see evidence for dust evolution in a TTauri star,
with a decreasing fraction of small amorphous and an increasing fraction of
crystalline particles closer to the star.

712.0699 | Fast-neutron induced pre-equilibrium reactions on 55Mn and 63,65Cu at
energies up to 40 MeV | Excitation functions were measured for the $^{55}$Mn(n,2n)$^{54}$Mn,
$^{55}$Mn(n,$\alpha$)$^{52}$V, $^{63}$Cu(n,$\alpha$)$^{60}$Co,
$^{65}$Cu(n,2n)$^{64}$Cu, and $^{65}$Cu(n,p)$^{65}$Ni reactions from 13.47 to
14.83 MeV. The experimental cross sections are compared with the results of
calculations including all activation channels for the stable isotopes of Mn
and Cu, for neutron incident energies up to 50 MeV. Within the energy range up
to 20 MeV the model calculations are most sensitive to the parameters related
to nuclei in the early stages of the reaction, while the model assumptions are
better established by analysis of the data in the energy range 20-40 MeV. While
the present analysis has taken advantage of both a new set of accurate measured
cross sections around 14 MeV and the larger data basis fortunately available
between 20 and 40 MeV for the Mn and Cu isotopes, the need of additional
measurements below as well as above 40 MeV is pointed out. Keywords: 55Mn,

712.07 | Localizing gravity on Maxwell gauged CP1 model in six dimensions | We shall consider about a 3-brane embedded in six-dimensional space-time with
a negative bulk cosmological constant. The 3-brane is constructed by a
topological soliton solution living in two-dimensional axially symmetric
transverse subspace. Similar to most previous works of six-dimensional soliton
models, our Maxwell gauged CP1 brane model can also achieve to localize gravity
around the 3-brane. The CP1 field is described by a scalar doublet and derived
from O(3) sigma model by projecting it onto two-dimensional complex space. In
that sense, our framework is more effective than other solitonic brane models
concerning with gauge theory. We shall also discuss about linear stability
analysis for our new model by fluctuating all fields.

712.0702 | Pontrjagin-Thom maps and the homology of the moduli stack of stable
curves | We study the singular homology (with field coefficients) of the moduli stack
of stable n-pointed complex curves of genus g (the Deligne-Mumford
compactification). Each of its irreducible boundary components determines via
the Pontrjagin-Thom construction a map to a certain infinite loop space whose
homology is well understood. We show that these maps are surjective on homology

interacting galaxies M51 (NGC5194/NGC5195) has been carried out on the basis of
the ACS/WFC images of the Hubble Space telescope. The distance to the system
has been determined by TRGB method and metallicity of red supergiants along the
NGC5194 radius has been measured. A comparison of the spacial distribution of
stars in the main galaxy NGC5194 with our empirical model of spiral galaxies
showed their similarity, in spite of interaction in system M51. It has been
discovered that the "feathers", arising as a result of the interaction of
galaxies, mainly consist of stars of intermediate age.

Riemann zeros. In this paper we first generalize this result by considering a
phase space delimited by two boundary functions in position and momenta, which
induce a fluctuation term in the counting of energy levels. We next quantize
the xp Hamiltonian, adding an interaction term that depends on two wave
functions associated to the classical boundaries in phase space. The general
model is solved exactly, obtaining a continuum spectrum with discrete bound
states embbeded in it. We find the boundary wave functions, associated to the
Berry-Keating regularization, for which the average Riemann zeros become
resonances. A spectral realization of the Riemann zeros is achieved exploiting
the symmetry of the model under the exchange of position and momenta which is
related to the duality symmetry of the zeta function. The boundary wave
functions, giving rise to the Riemann zeros, are found using the Riemann-Siegel
formula of the zeta function. Other Dirichlet L-functions are shown to find a
natural realization in the model.

712.0707 | System reliability and weighted lattice polynomials | The lifetime of a system of connected units under some natural assumptions
can be represented as a random variable Y defined as a weighted lattice
polynomial of random lifetimes of its components. As such, the concept of a
random variable Y defined by a weighted lattice polynomial of (lattice-valued)
random variables is considered in general and in some special cases. The
central object of interest is the cumulative distribution function of Y. In
particular, numerous results are obtained for lattice polynomials and weighted
lattice polynomials in case of independent arguments and in general. For the
general case, the technique consists in considering the joint probability

712.0708 | Transfer Principle for the Fundamental Lemma | The purpose of this paper is to explain how the identities of various
fundamental lemmas fall within the scope of the transfer principle, a general
result that allows to transfer theorems about identities of p-adic integrals
from one collection of fields to others. In particular, once the fundamental
lemma has been established for one collection of fields (for example, fields of
positive characteristic), it is also valid for others (fields of characteristic
zero).

712.0709 | New water masers in Seyfert and FIR bright galaxies. II | Recently, a relationship between the water maser detection rate and far
infrared (FIR) flux density has been found as a result of a 22 GHz maser survey
in a sample comprised of northern galaxies with 100 micron flux density > 50 Jy
and a declination >-30 degrees. The survey has been extended toward galaxies
with lower FIR flux densities in order to confirm this correlation and to
discover additional maser sources for relevant follow-up interferometric
studies. A sample of 41 galaxies with 30 Jy < S(100 micron) < 50 Jy and Dec. >
-30 degrees was observed with the 100-m telescope at Effelsberg in a search for
the 22 GHz water vapor line. The average 3-sigma noise level of the survey is
40 mJy for a 1 km/s channel, corresponding to a detection threshold for the
isotropic maser luminosity of about 0.5 solar luminosities at a distance of 25
Mpc. Two detections are reported: a megamaser with an isotropic luminosity of
approximately 35 solar luminosities in the Seyfert/HII galaxy NGC613 and a
kilomaser of approximately 1 solar luminosity in the merger system
NGC520.[abridged]
| astro-ph | recently a relationship between the water maser detection rate and far infrared fir flux density has been found as a result of a 22 ghz maser survey in a sample comprised of northern galaxies with 100 micron flux density 50 jy and a declination 30 degrees the survey has been extended toward galaxies with lower fir flux densities in order to confirm this correlation and to discover additional maser sources for relevant followup interferometric studies a sample of 41 galaxies with 30 jy s100 micron 50 jy and dec 30 degrees was observed with the 100m telescope at effelsberg in a search for the 22 ghz water vapor line the average 3sigma noise level of the survey is 40 mjy for a 1 kms channel corresponding to a detection threshold for the isotropic maser luminosity of about 05 solar luminosities at a distance of 25 mpc two detections are reported a megamaser with an isotropic luminosity of approximately 35 solar luminosities in the seyferthii galaxy ngc613 and a kilomaser of approximately 1 solar luminosity in the merger system ngc520abridged | [['recently', 'a', 'relationship', 'between', 'the', 'water', 'maser', 'detection', 'rate', 'and', 'far', 'infrared', 'fir', 'flux', 'density', 'has', 'been', 'found', 'as', 'a', 'result', 'of', 'a', '22', 'ghz', 'maser', 'survey', 'in', 'a', 'sample', 'comprised', 'of', 'northern', 'galaxies', 'with', '100', 'micron', 'flux', 'density', '50', 'jy', 'and', 'a', 'declination', '30', 'degrees', 'the', 'survey', 'has', 'been', 'extended', 'toward', 'galaxies', 'with', 'lower', 'fir', 'flux', 'densities', 'in', 'order', 'to', 'confirm', 'this', 'correlation', 'and', 'to', 'discover', 'additional', 'maser', 'sources', 'for', 'relevant', 'followup', 'interferometric', 'studies', 'a', 'sample', 'of', '41', 'galaxies', 'with', '30', 'jy', 's100', 'micron', '50', 'jy', 'and', 'dec', '30', 'degrees', 'was', 'observed', 'with', 'the', '100m', 'telescope', 'at', 'effelsberg', 'in', 'a', 'search', 'for', 'the', '22', 'ghz', 'water', 'vapor', 'line', 'the', 'average', '3sigma', 'noise', 'level', 'of', 'the', 'survey', 'is', '40', 'mjy', 'for', 'a', '1', 'kms', 'channel', 'corresponding', 'to', 'a', 'detection', 'threshold', 'for', 'the', 'isotropic', 'maser', 'luminosity', 'of', 'about', '05', 'solar', 'luminosities', 'at', 'a', 'distance', 'of', '25', 'mpc', 'two', 'detections', 'are', 'reported', 'a', 'megamaser', 'with', 'an', 'isotropic', 'luminosity', 'of', 'approximately', '35', 'solar', 'luminosities', 'in', 'the', 'seyferthii', 'galaxy', 'ngc613', 'and', 'a', 'kilomaser', 'of', 'approximately', '1', 'solar', 'luminosity', 'in', 'the', 'merger', 'system', 'ngc520abridged']] | [-0.06415345832721282, 0.09208370924746094, 0.025426163727491253, 0.058779897825992376, -0.04123174440310373, -0.04586766745091421, 0.07601070548223574, 0.44929571089855697, -0.06276555440920052, -0.4193218921884726, 0.10739946826750815, -0.33760514938519837, 0.04188618364436078, 0.16179613157906858, 0.03815368406137841, -0.0021530066687619645, 0.007140750207512056, -0.10879355238219145, -0.05968062612254404, -0.21362211970786044, 0.17167310478786627, 0.13682224243184773, 0.20927744059123646, -0.013128299539708822, 0.14103825214334717, -0.19935720106507887, -0.10268658959953966, -0.049719131654286285, -0.13264972548721368, 0.03914498792182507, 0.3099397348271588, 0.08918404441766209, 0.23766789783389533, -0.280441388755752, -0.18398520638403287, 0.05952971191724268, 0.11752638535174188, 0.0021304738442124117, 0.00953691887095739, -0.29229014509457485, 0.0696511378901153, -0.18153606058166777, -0.2015930505964042, 0.18645994955052933, 0.1120864337199699, 0.029608858212576073, -0.20617228158442816, 0.16084081565403502, -0.02242822222422156, 0.18336771707455654, -0.11980905765825409, -0.17897509981280899, -0.048159384615929786, -0.00038487788837003167, -0.058895551460126865, 0.14587351547025992, 0.18700283124916633, -0.1143231351799358, -0.06905339657701288, 0.34743620840948347, -0.0925959730014405, 0.023857189418674356, 0.21153153638496186, -0.23707617256964036, -0.1756487965115509, 0.26682673297535714, 0.1509440518957747, 0.06393066501918401, -0.2045050063907132, -0.03654702637366961, -0.029846948849058336, 0.29883988438921294, 0.10441882642364855, 0.07692984855047488, 0.30426613462425894, 0.117670455392408, 0.12346031497848237, 0.12352279264816625, -0.37274494098951927, 0.0012519017564353802, -0.2521544873528972, -0.09308734772010643, -0.10319457330483164, 0.17678016825581738, -0.11428353163809318, -0.031424647286247546, 0.3725862229390249, 0.11200471855581627, 0.19303311788425456, 0.11312918529298556, 0.26163045751814873, 0.06701808068888146, 0.1206230695575139, 0.121629201167784, 0.36576058208616186, 0.18800582232132637, 0.12174008844557119, -0.15328342258393512, -0.011955999395689048, -0.056661083647128886] |

a pseudo-photon is introduced at variational level and is justified by the
violation of the Bianchi identities in conceptual systems, either in the
presence of magnetic monopoles or non-regular external fields, not being

quantum field theory regimes there are observable consequences both for the
magnetic momenta and second order vacuum polarization radiative corrections in

in seven fields at the center and periphery of the galaxy NGC2366. The
variation of the number density of stars of various ages with galactocentric
radius and along the minor axis of the galaxy are determined. The boundaries of
the thin and thick disks of the galaxy are found. The inferred sizes of the
subsystems of NGC2366 ($Z_{thin} = 4$ kpc and $Z_{thick} = 8$ kpc for the thin

for a stellar halo is found at the periphery of NGC2366 beyond the thick disk

the scattering length in the proximity of a Feshbach resonance. We report the
observation of two new Feshbach resonances on |F = 1;mF = 0> state. The narrow
(broad) resonance of 7 G (34 G) width is detected at 831 +- 4 G (884 +4 -13 G).
Position of the scattering length zero crossing between the resonances is found
at 836 +- 4 G. The broad resonance is shown to be favorable for run away
evaporation which we perform in a crossed-beam optical dipole trap. Starting

712.0718 | Interacting coronae of two T Tauri stars: first observational evidence
for solar-like helmet streamers | Context {The young binary system V773 Tau A exhibits a persistent radio
flaring activity that gradually increases from a level of a few mJy at
apoastron to more than 100 mJy at periastron. Interbinary collisions between
very large (> 15 R) magnetic structures anchored on the two rotating stars of
the system have been proposed to be the origin of these periodic radio flares.
Magnetic structures extended over tens of stellar radii, that can also account
for the observed fast decay of the radio flares, seem to correspond to the
typical solar semi-open quite extended magnetic configurations called helmet
streamers.} Aims {We aim to find direct observational evidence for the
postulated, solar-like, coronal topologies.} Methods {We performed
seven-consecutive-day VLBI observations at 8.4 GHz using an array consisting of
the VLBA and the 100-m Effelsberg telescope.} Results {Two distintive
structures appear in the radio images here presented. They happen to be
associated with the primary and secondary stars of the V773 Tau A system. In
one image (Fig.2-B) the two features are extended up to 18 R each and are
nearly parallel revealing the presence of two interacting helmet streamers. One
image (Fig.2-E) taken a few hours after a flare monitored by the 100-m
Effelsberg telescope shows one elongated fading structure substantially rotated
with respect to those seen in the B run. The same decay scenario is seen in
Fig.2-G for the helmet streamer associated with the other star.} Conclusions
{This is the very first direct evidence revealing that even if the flare origin
is magnetic reconnection due to interbinary collision, both stars independently
emit in the radio range with structures of their own. These structures are
helmet streamers, observed for the first time in stars other than the Sun.}

712.0719 | Dissipative discrete breathers in rf SQUID metamaterials | The existence and stability of dissipative discrete breathers (DDBs) in rf
superconducting quantum interference device (SQUID) arrays in both one and two
dimensions is investigated numerically. In an rf SQUID array, the nonlinearity
which is intrinsic to each SQUID due to the presence of the Josephson junction
(on-site nonlinearity), along with the weak coupling of each SQUID to its
nearest neighbors through magnetic forces, result in the appearance of discrete
breathers. We analyze several discrete breather excitations, both in one and
two dimensions, which are subjected to unavoidable losses. These losses,
however, are counter-balanced by an external flux source leading to linearly
stable discrete breather structures up to relatively large coupling parameters.
We show that DDB excitations may locally alter the magnetic response of array

712.0722 | Classical capacity of quantum channels with general Markovian correlated
noise | The classical capacity of a quantum channel with arbitrary Markovian
correlated noise is evaluated. For the general case of a channel with long-term
memory, which corresponds to a Markov chain which does not converge to
equilibrium, the capacity is expressed in terms of the communicating classes of

712.0724 | Understanding the small object argument | The small object argument is a transfinite construction which, starting from
a set of maps in a category, generates a weak factorisation system on that
category. As useful as it is, the small object argument has some problematic
aspects: it possesses no universal property; it does not converge; and it does
not seem to be related to other transfinite constructions occurring in
categorical algebra. In this paper, we give an "algebraic" refinement of the
small object argument, cast in terms of Grandis and Tholen's natural weak
factorisation systems, which rectifies each of these three deficiencies.

712.0725 | Seismic evolution of low/intermediate mass PMS stars | This article presents a study of the evolution of the internal structure and
seismic properties expected for low/intermediate mass Pre-Main Sequence (PMS)
stars. Seismic and non-seismic properties of PMS stars were analysed. This was
done using 0.8 to 4.4M$_\odot$ stellar models at stages ranging from the end of
the Hayashi track up to the Zero-Age Main-Sequence (ZAMS). This research
concludes that, for intermediate-mass stars (M$>$1.3M$_\odot$), diagrams
comparing the effective temperature ($T_{eff}$) against the small separation
can provide an alternative to Christensen-Dalsgaard (C-D) diagrams. The impact

712.0726 | The signature of evolving turbulence in quiet solar wind as seen by
ULYSSES | Solar wind fluctuations, such as magnetic field or velocity, show power law
power spectra suggestive both of an inertial range of intermittent turbulence
(with $\sim -5/3$ exponent) and at lower frequencies, of fluctuations of
coronal origin (with $\sim -1$ exponent). The ULYSSES spacecraft spent many
months in the quiet fast solar wind above the Sun's polar coronal holes in a
highly ordered magnetic field. We use statistical analysis methods such as the
generalized structure function (GSF) and extended self-similarity (ESS) to
quantify the scaling of the moments of the probability density function of
fluctuations in the magnetic field. The GSFs give power law scaling in the
``$f^{-1}$'' range of the form $<| y(t+\tau)-y(t)|^{m}>\sim\tau^{\zeta(m)}$,
but ESS is required to reveal scaling in the inertial range, which is of the
form $<| y(t+\tau)-y(t)|^{m}>\sim [g(\tau)]^{\zeta(m)}$. We find that $g(\tau)$
is independent of spacecraft position and
$g(\tau)\sim\tau^{-log_{10}(\tilde{\lambda}\tau)}$. The ``$f^{-1}$'' scaling
fluctuates with radial spacecraft position. This confirms that, whereas the
``$f^{-1}$'' fluctuations are directly influenced by the corona, the inertial
range fluctuations are consistent with locally evolving turbulence, but with an
``envelope'' $g(\tau)$, which captures the formation of the quiet fast solar
wind.

712.0727 | Semiclassical and Quantum Black Holes and their Evaporation, de Sitter
and Anti-de Sitter Regimes, Gravitational and String Phase Transitions | An effective string theory in physically relevant cosmological and black hole
space times is reviewed. Explicit computations of the quantum string entropy,
partition function and quantum string emission by black holes (Schwarzschild,
rotating, charged, asymptotically flat, de Sitter dS and AdS space times) in
the framework of effective string theory in curved backgrounds provide an
amount of new quantum gravity results as: (i) gravitational phase transitions
appear with a distinctive universal feature: a square root branch point
singularity in any space time dimensions. This is of the type of the de Vega -
Sanchez transition for the thermal self-gravitating gas of point particles.
(ii) There are no phase transitions in AdS alone. (iii) For $dS$ background,
upper bounds of the Hubble constant H are found, dictated by the quantum string
phase transition.(iv) The Hawking temperature and the Hagedorn temperature are
the same concept but in different (semiclassical and quantum) gravity regimes
respectively. (v) The last stage of black hole evaporation is a microscopic
string state with a finite string critical temperature which decays as usual
quantum strings do in non-thermal pure quantum radiation (no information
loss).(vi) New lower string bounds are given for the Kerr-Newman black hole
angular momentum and charge, which are entirely different from the upper
classical bounds. (vii) Semiclassical gravity states undergo a phase transition
into quantum string states of the same system, these states are duals of each
other in the precise sense of the usual classical-quantum (wave-particle)
duality, which is universal irrespective of any symmetry or isommetry of the
space-time and of the number or the kind of space-time dimensions.

712.073 | Possible agreement of wave function reduction from the basic principles
of quantum mechanics | Reduction is shown to be a possible consequence of the basic principles of
quantum mechanics, involving no branching of the quantum state of the universe.
The key feature of a measurement is attributed to the creation of macroscopic
germs of ionized tracks, bubbles, sparks and so on, in a superposed quantum
state, the main mechanism being a breaking and a restoration of
``classicality'' in nearby macroscopic objects and their small patterns. A new

importance is compared. Specifically, we include jet fragmentation, jet-plasma
interactions, the emission of radiation from the thermal medium and from
primordial hard collisions. Our calculations consistently take into account jet
energy loss, as evaluated in the AMY formalism. We obtain results for the

Cantor set is orbit equivalent to the AF relation. By a `small' extension we
mean an equivalence relation generated by the minimal AF equivalence relation

712.0734 | Precision tests of Standard Model with leptonic and semileptonic kaon
decays | Till the middle of 2004 it appeared that the unitarity relation
Vud^2+Vus^2+Vub^2=1 might not hold at the 2.3sigma level. At that time,
however, Vus was inferred from old experimental data. Since then, a large
experimental and theoretical effort has been invested leading to a removal of
the problem. Thanks to the new and improved measurements by BNL-E865, KLOE,
KTeV, ISTRA+ and NA48, the Kl3 decay rate moved up so that Vus is now
consistent with unitarity. On the theory side, much progress has been made in
order to tame the systematic uncertainties related to the computation of the
Kl3 form factors.
This joint progress allowed to assess the validity of the CKM unitarity
relation at the level of less than $1%.
Recent measurements of kaon decays contributing to the determination of
Vus, Vus/Vud are summarized, and up-to-date evaluations of Vusf0 and Vus are
presented. In addition, we discuss the sensitivity of Kl3 and Kl2 decays to
various scenarios of physics beyond Standard Model.

712.0735 | Higgs Structures of Dyonic Instantons | We study Higgs field configurations of dyonic instantons in spontaneously
broken (4+1)-dimensional Yang-Mills theory. The adjoint scalar field solutions
to the covariant Laplace equation in the ADHM instanton background are
constructed in general noncanonical basis, and they are used to study
explicitly the Higgs field configurations of dyonic instantons when the gauge
fields are taken by Jackiw-Nohl-Rebbi instanton solutions. For these solutions
corresponding to small instanton number we then consider in some detail the
zero locus of the Higgs field, which describes the cross section of supertubes
connecting parallel D4-branes in string theory. Also the information on the

semiquantitative agreement between simulation and theory, except for processes
that occur on intermediate length scales between the compressibility plateau

the onset of slow relaxation in a glass-forming melt can be described in terms

712.0738 | On the minimum mass of reionization sources | By means of carefully calibrated semi-analytical reionization models, we
estimate the minimum mass of star-forming haloes required to match the current
data. Models which do not include haloes of total mass M < 10^9 M_sun fail at
reproducing the Gunn-Peterson and electron scattering optical depths
simultaneously, as they contribute too few (many) photons at high (low, z
\approx 6) redshift. Marginally acceptable solutions require haloes with M
\approx 5 \times 10^7 M_sun at z \approx 10, corresponding to virial

712.0739 | A new period determination for the close PG1159 binary
SDSSJ212531.92-010745.9 | Methods to measure masses of PG1159 stars in order to test evolutionary
scenarios are currently based on spectroscopic masses or asteroseismological
mass determinations. One recently discovered PG1159 star in a close binary
system may finally allow the first dynamical mass determination, which has so
far been analysed on the basis of one SDSS spectrum and photometric monitoring.
In order to be able to phase future radial velocity measurements of the
system SDSSJ212531.92-010745.9, we follow up on the photometric monitoring of
this system to provide a solid observational basis for an improved orbital
ephemeris determination.
New white-light time series of the brightness variation of
SDSSJ212531.92-010745.9 with the Tuebingen 80cm and Goettingen 50cm telescopes
extend the monitoring into a second season (2006), tripling the length of
overall observational data available, and significantly increasing the time
base covered.
We give the ephemeris for the orbital motion of the system, based on a sine
fit which now results in a period of 6.95573(5)h, and discuss the associated
new amplitude determination in the context of the phased light curve variation
profile. The accuracy of the ephemeris has been improved by more than one order
of magnitude compared to that previously published for 2005 alone.

712.074 | Phase noise measurements in long fiber interferometers for quantum
repeaters applications | Many protocols for long distance quantum communication require
interferometric phase stability over long distances of optical fibers. In this
paper we investigate the phase noise in long optical fibers both in laboratory
environment and in installed commercial fibers in an urban environment over
short time scales (up to hundreds of us). We show that the phase fluctuations
during the travel time of optical pulses in long fiber loops are small enough
to obtain high visibility first order interference fringes in a Sagnac
interferometer configuration for fiber lengths up to 75 km. We also measure
phase fluctuations in a Mach-Zehnder interferometer in installed fibers with
arm length 36.5 km. We verify that the phase noise respects gaussian
distribution and measure the mean phase change as a function of time
difference. The typical time needed for a mean phase change of 0.1 rad is of
order of 100 us, which provides information about the time scale available for
active phase stabilization. Our results are relevant for future implementations
of quantum repeaters in installed optical fiber networks.
| quant-ph | many protocols for long distance quantum communication require interferometric phase stability over long distances of optical fibers in this paper we investigate the phase noise in long optical fibers both in laboratory environment and in installed commercial fibers in an urban environment over short time scales up to hundreds of us we show that the phase fluctuations during the travel time of optical pulses in long fiber loops are small enough to obtain high visibility first order interference fringes in a sagnac interferometer configuration for fiber lengths up to 75 km we also measure phase fluctuations in a machzehnder interferometer in installed fibers with arm length 365 km we verify that the phase noise respects gaussian distribution and measure the mean phase change as a function of time difference the typical time needed for a mean phase change of 01 rad is of order of 100 us which provides information about the time scale available for active phase stabilization our results are relevant for future implementations of quantum repeaters in installed optical fiber networks | [['many', 'protocols', 'for', 'long', 'distance', 'quantum', 'communication', 'require', 'interferometric', 'phase', 'stability', 'over', 'long', 'distances', 'of', 'optical', 'fibers', 'in', 'this', 'paper', 'we', 'investigate', 'the', 'phase', 'noise', 'in', 'long', 'optical', 'fibers', 'both', 'in', 'laboratory', 'environment', 'and', 'in', 'installed', 'commercial', 'fibers', 'in', 'an', 'urban', 'environment', 'over', 'short', 'time', 'scales', 'up', 'to', 'hundreds', 'of', 'us', 'we', 'show', 'that', 'the', 'phase', 'fluctuations', 'during', 'the', 'travel', 'time', 'of', 'optical', 'pulses', 'in', 'long', 'fiber', 'loops', 'are', 'small', 'enough', 'to', 'obtain', 'high', 'visibility', 'first', 'order', 'interference', 'fringes', 'in', 'a', 'sagnac', 'interferometer', 'configuration', 'for', 'fiber', 'lengths', 'up', 'to', '75', 'km', 'we', 'also', 'measure', 'phase', 'fluctuations', 'in', 'a', 'machzehnder', 'interferometer', 'in', 'installed', 'fibers', 'with', 'arm', 'length', '365', 'km', 'we', 'verify', 'that', 'the', 'phase', 'noise', 'respects', 'gaussian', 'distribution', 'and', 'measure', 'the', 'mean', 'phase', 'change', 'as', 'a', 'function', 'of', 'time', 'difference', 'the', 'typical', 'time', 'needed', 'for', 'a', 'mean', 'phase', 'change', 'of', '01', 'rad', 'is', 'of', 'order', 'of', '100', 'us', 'which', 'provides', 'information', 'about', 'the', 'time', 'scale', 'available', 'for', 'active', 'phase', 'stabilization', 'our', 'results', 'are', 'relevant', 'for', 'future', 'implementations', 'of', 'quantum', 'repeaters', 'in', 'installed', 'optical', 'fiber', 'networks']] | [-0.2155870735757695, 0.18807473588788723, -0.09535439643438841, 0.012194306149425778, 0.006693805664263922, -0.12589301297778327, 0.04431311199214074, 0.4776145445327435, -0.2495837757583365, -0.29568632313414295, 0.11231151085223831, -0.2472187711204263, -0.09106730595873348, 0.23562878504898613, -0.06626831666946453, 0.08227370562762472, 0.05524174397110126, 0.007851284837628576, -0.04859050279536723, -0.20532612916652176, 0.20277838774183338, 0.07026126282323077, 0.2846315459310794, 0.006879663403980948, 0.12681075224074825, -0.01918345917519396, -0.011499545108741042, -0.030639871398265333, -0.12267950706037722, 0.031179004667283988, 0.26835513354182755, 0.042963805827900936, 0.23153032092163447, -0.4350105868438366, -0.22216108319317474, 0.13535187647667254, 0.1190921421572245, 0.100973100087675, 0.027916030588977295, -0.29696079584416646, 0.03091885401678657, -0.16243721125647426, -0.1570077452637341, -0.017688576062477524, 0.04990603745347638, 0.045474365631910575, -0.20697441922859341, 0.02521625850279414, -0.013745005434544906, 0.07392269164613507, 0.021596016635283315, -0.030103480020516563, 0.07038335976506659, 0.15938146338776696, -0.04643968729992751, 0.04758533788510416, 0.12278342481713271, -0.09933035655733968, -0.07459731003398011, 0.3639746130840189, -0.11560153604174654, -0.07844383972054668, 0.11817911683967144, -0.19418820090613317, -0.05619638633175657, 0.18141400975164498, 0.21245991630561986, 0.08467658808529806, -0.10508043628557981, -0.02133066971296573, 0.05289169281838869, 0.2520626769722279, 0.12069955921528497, 0.1526142897903277, 0.19224406210384493, 0.20155204460827697, 0.08874743926872757, 0.12373236299829622, -0.19216938665532773, -0.1232438091049506, -0.3040560606396061, -0.16345078896345763, -0.15628134341503697, 0.04658956327689705, -0.11408330412730762, -0.11011376528567153, 0.38083113302829963, 0.17023675253443504, 0.17146375465699226, 0.05812060774167486, 0.33264564372727584, 0.019805156839904428, 0.10499965189822318, 0.04325736538458873, 0.27684125225809025, 0.13482156590138422, 0.14513396027621053, -0.18982270223773673, 0.02629780538390851, -0.018005657925045694] |

measurements of semiconducting materials | We perform broadband phase sensitive measurements of the reflection
coefficient from 45 MHz up to 20 GHz employing a vector network analyzer with a
2.4 mm coaxial sensor which is terminated by the sample under test. While the
material parameters (conductivity and permittivity) can be easily extracted
from the obtained impedance data if the sample is metallic, no direct solution
is possible if the material under investigation is an insulator. Focusing on
doped semiconductors with largely varying conductivity, here we present a
closed calibration and evaluation procedure for frequencies up to 5 GHz, based
on the rigorous solution for the electromagnetic field distribution inside the
sample combined with the variational principle; basically no limiting
assumptions are necessary. A simple static model based on the electric current
distribution proves to yield the same frequency dependence of the complex
conductivity up to 1 GHz. After a critical discussion we apply the developed
method to the hopping transport in Si:P at temperature down to 1 K.

712.0742 | New Light Curves and Spectra of the close PG1159 Binary System
SDSSJ212531.92-010745.9 | Methods to measure masses of PG1159 stars in order to test evolutionary
scenarios are currently based on spectroscopic masses or asteroseismological
mass determinations. SDSSJ212531.92-010745.9, a recently discovered PG1159 star
in a close binary system, may finally allow the first dynamical mass
determination, and has so far been analysed on the basis of one SDSS spectrum
and photometric monitoring.
In order to be able to phase radial velocity measurements of the system
SDSSJ212531.92-010745.9, we have followed up the photometric monitoring of this
system. New white light time series of the brightness variation of
SDSSJ212531.92-010745.9 with the Tuebingen 80cm and Goettingen 50cm telescopes
extend the monitoring into a second season (2006). We give the improved
ephemeris for the orbital motion of the system, based on a sine fit which now
results in a period of 6.95573(5)h.
In 2007, we have obtained a series of phase-resolved medium-resolution
spectra with the TWIN spectrograph at the 3.5m telescope at Calar Alto, which
will allow us to derive the radial velocity curves for both components of the
system, and to perform spectral analyses of the irradiating and irradiated
components at different phases. We briefly describe the newly obtained spectra.
The light curve and radial velocities combined will allow us to carry out a
mass determination.

712.0744 | Computational Chemotaxis in Ants and Bacteria over Dynamic Environments | Chemotaxis can be defined as an innate behavioural response by an organism to
a directional stimulus, in which bacteria, and other single-cell or
multicellular organisms direct their movements according to certain chemicals
in their environment. This is important for bacteria to find food (e.g.,
glucose) by swimming towards the highest concentration of food molecules, or to
flee from poisons. Based on self-organized computational approaches and similar
stigmergic concepts we derive a novel swarm intelligent algorithm. What strikes
from these observations is that both eusocial insects as ant colonies and
bacteria have similar natural mechanisms based on stigmergy in order to emerge
coherent and sophisticated patterns of global collective behaviour. Keeping in
mind the above characteristics we will present a simple model to tackle the
collective adaptation of a social swarm based on real ant colony behaviors (SSA
algorithm) for tracking extrema in dynamic environments and highly multimodal
complex functions described in the well-know De Jong test suite. Later, for the
purpose of comparison, a recent model of artificial bacterial foraging (BFOA
algorithm) based on similar stigmergic features is described and analyzed.
Final results indicate that the SSA collective intelligence is able to cope and
quickly adapt to unforeseen situations even when over the same cooperative
foraging period, the community is requested to deal with two different and
contradictory purposes, while outperforming BFOA in adaptive speed. Results
indicate that the present approach deals well in severe Dynamic Optimization
problems.

712.0745 | Neutron reflection from the surface of normal and superfluid 4He | The reflection of neutrons from a helium surface has been observed for the
first time. The 4He surface is smoother in the superfluid state at 1.54 K than
in the case of the normal liquid at 2.3 K. In the superfluid state we also
observe a surface layer ~200 Angstroms thick which has a subtly different

712.0747 | Spinor-Vector Duality in N=2 Heterotic String Vacua | Classification of the N=1 space-time supersymmetric fermionic Z2XZ2
heterotic-string vacua with symmetric internal shifts, revealed a novel
spinor-vector duality symmetry over the entire space of vacua, where the S_t
<-> V duality interchanges the spinor plus anti-spinor representations with
vector representations. In this paper we demonstrate that the spinor--vector
duality exists also in fermionic Z2 heterotic string models, which preserve N=2
space-time supersymmetry. In this case the interchange is between spinorial and
vectorial representations of the unbroken SO(12) GUT symmetry. We provide a
general algebraic proof for the existence of the S_t <-> V duality map. We
present a novel basis to generate the free fermionic models in which the ten
dimensional gauge degrees of freedom are grouped into four groups of four, each
generating an SO(8) modular block. In the new basis the GUT symmetries are
produced by generators arising from the trivial and non--trivial sectors, and
due to the triality property of the SO(8) representations. Thus, while in the
new basis the appearance of GUT symmetries is more cumbersome, it may be more
instrumental in revealing the duality symmetries that underly the string vacua.

712.0748 | Understanding the nucleation mechanisms of Carbon Nanotubes in catalytic
Chemical Vapor Deposition | The nucleation of carbon caps on small nickel clusters is studied using a
tight binding model coupled to grand canonical Monte Carlo simulations. It
takes place in a well defined carbon chemical potential range, when a critical
concentration of surface carbon atoms is reached. The solubility of carbon in
the outermost Ni layers, that depends on the initial, crystalline or
disordered, state of the catalyst and on the thermodynamic conditions, is
therefore a key quantity to control the nucleation.

712.0749 | Instabilities at vicinal crystal surfaces - competition between the
electromigration of the adatoms and the kinetic memory effect | We studied the step dynamics during sublimation and growth in the presence of
electromigration force acting on the adatoms. In the limit of fast surface
diffusion and slow kinetics of atom attachment-detachment at the steps we
formulate a model free of the quasi-static approximation in the calculation of
the adatom concentration on the terraces. Numerical integration of the
equations for the time evolution of the adatom concentrations and the equations
of step motion reveals two different step bunching instabilities: 1) step
density waves (small bunches which do not manifest any coarsening) induced by
the kinetic memory effect and 2) step bunching with coarsening when the
dynamics is dominated by the electromigration. The model developed in this
paper also provides very instructive illustrations of the Popkov-Krug dynamical
phase transition during sublimation and growth of a vicinal crystal surface.

712.075 | Vibration-induced correction to the current through a single molecule | We provide analytical results for the perturbative correction to the
current-voltage relation through a vibrating molecule for weak electron-phonon
coupling. The nonlinear conductance exhibits a step-like feature at $eV=\hbar
\omega_0$, where $\omega_0$ is the vibration frequency. We establish criteria
for the sign change of the step in the conductance (up or down). This

712.0751 | Melting of alloys along grain boundaries | We discuss melting of alloys along grain boundaries as a free boundary
problem for two moving solid-liquid interfaces. One of them is the melting
front and the other is the solidification front. The presence of the triple
junction plays an important role in controlling the velocity of this process.
The interfaces strongly interact via the diffusion field in the thin liquid
layer between them. In the liquid film migration (LFM) mechanism the system
chooses a more efficient kinetic path, which is controlled by diffusion in the
liquid film on relatively short distances. However, only weak coherency strain
energy is the effective driving force for LFM in the case of melting of
one-phase alloys.
The process with only one melting front would be controlled by the very slow
diffusion in the mother solid phase on relatively large distances.

712.0753 | Surface dissipation in nanoelectromechanical systems: Unified
description with the standard tunneling model and effects of metallic
electrodes | By modifying and extending recent ideas [C. Seoanez et al., Europhys. Lett.
78, 60002 (2007)], a theoretical framework to describe dissipation processes in
the surfaces of vibrating micro- and nanoelectromechanical devices, thought to
be the main source of friction at low temperatures, is presented. Quality
factors as well as frequency shifts of flexural and torsional modes in doubly
clamped beams and cantilevers are given, showing the scaling with dimensions,
temperature, and other relevant parameters of these systems. Full agreement
with experimental observations is not obtained, leading to a discussion of
limitations and possible modifications of the scheme to reach a quantitative
fitting to experiments. For nanoelectromechanical systems covered with metallic

712.0754 | Asymptotic analysis of vibrating system containing stiff-heavy and
flexible-light parts | A model of strongly inhomogeneous medium with simultaneous perturbation of
rigidity and mass density is studied. The medium has strongly contrasting
physical characteristics in two parts with the ratio of rigidities being
proportional to a small parameter $\epsilon$. Additionally, the ratio of mass
densities is of order $\epsilon^{-1}$. We investigate the asymptotic behaviour
of spectrum and eigensubspaces as $\epsilon\to 0$. Complete asymptotic
expansions of eigenvalues and eigenfunctions are constructed and justified.
We show that the limit operator is nonself-adjoint in general and possesses
two-dimensional Jordan cells in spite of the singular perturbed problem is
associated with a self-adjoint operator in appropriated Hilbert space
$L_\epsilon$. This may happen if the metric in which the problem is
self-adjoint depends on small parameter $\epsilon$ in a singular way. In
particular, it leads to a loss of completeness for the eigenfunction
collection. We describe how root spaces of the limit operator approximate
eigenspaces of the perturbed operator.

712.0756 | Modeling X-ray Loops and EUV "Moss" in an Active Region Core | The Soft X-ray intensity of loops in active region cores and corresponding
footpoint, or moss, intensity observed in the EUV remain steady for several
hours of observation. The steadiness of the emission has prompted many to
suggest that the heating in these loops must also be steady, though no direct
comparison between the observed X-ray and EUV intensities and the steady
heating solutions of the hydrodynamic equations has yet been made. In this
paper, we perform these simulations and simultaneously model the X-Ray and EUV
moss intensities in one active regioncore with steady uniform heating. To
perform this task, we introduce a new technique to constrain the model
parameters using the measured EUV footpoint intensity to infer a heating rate.
We find that a filling factor of 8% and loops that expand with height provides
the best agreement with the intensity in two X-ray filters, though the
simulated SXT Al12 intensity is 147% the observed intensity and the SXT AlMg
intensity is 80% the observed intensity. From this solution, we determine the
required heating rate scales as ${\bar{B}}^{0.29} L^{-0.95}$. Finally we
discuss the future potential of this type of modeling, such as the ability to
use density measurements to fully constrain filling factor, and its
shortcomings, such as the requirement to use potential field extrapolations to
approximate the coronal field.

712.0757 | Transport through a double quantum dot system with non-collinearly
polarized leads | We investigate linear and non-linear transport in a double quantum dot system
weakly coupled to spin-polarized leads.
In the linear regime, the conductance as well as the non-equilibrium spin
accumulation are evaluated in analytic form. The conductance as a function of
the gate voltage exhibits four peaks of different height, with mirror symmetry
with respect to the charge neutrality point. As the polarization angle is
varied, the position and shape of the peaks changes in a characteristic way
which preserves the electron-hole symmetry of the problem. In the nonlinear
regime negative differential conductance features occur for non collinear
magnetisations of the leads. In the considered sequential tunneling limit, the
tunneling magneto resistance (TMR) is always positive with a characteristic

Magnetic Nanodots | We found, by micromagnetic numerical and analytical calculations, that the
clockwise (CW) and counterclockwise (CCW) circular-rotational motions of a
magnetic vortex core in a soft magnetic circular nanodot are the elementary
eigenmodes existing in the gyrotropic motion with respect to the corresponding
CW and CCW circular-rotational-field eigenbasis. Any steady-state vortex
gyrotropic motions driven by a linearly polarized oscillating in-plane magnetic
field in the linear regime can be perfectly understood according to the
superposition of the two circular eigenmodes, which show asymmetric resonance
characteristics reflecting the vortex polarization. The relative magnitudes in
the amplitude and phase between the CCW and CW eigenmodes determine the
elongation and orientation of the orbital trajectories of the vortex core
motions, respectively, which trajectories vary with the polarization and
chirality of the given vortex as well as the field frequency across the
resonance frequency.

efficiently in the cotunneling regime. As an example, we consider a system of
two quantum dots in the Kondo regime, the two spins coupled by an
antiferromagnetic exchange interaction and each dot tunnel coupled to two
leads. Calculating the nonequilibrium density matrix and the corresponding
current, we demonstrate the importance of the off-diagonal terms in the
presence of an applied magnetic field and a finite bias voltage.

712.0761 | Sodium Absorption From the Exoplanetary Atmosphere of HD189733b Detected
in the Optical Transmission Spectrum | We present the first ground-based detection of sodium absorption in the
transmission spectrum of an extrasolar planet. Absorption due to the atmosphere
of the extrasolar planet HD189733b is detected in both lines of the NaI
doublet. High spectral resolution observations were taken of eleven transits
with the High Resolution Spectrograph (HRS) on the 9.2 meter Hobby-Eberly
Telescope (HET). The NaI absorption in the transmission spectrum due to
HD189733b is (-67.2 +/- 20.7) x 10^-5 deeper in the ``narrow'' spectral band
that encompasses both lines relative to adjacent bands. The 1-sigma error
includes both random and systematic errors, and the detection is >3-sigma. This
amount of relative absorption in NaI for HD189733b is ~3x larger than detected
for HD209458b by Charbonneau et al. (2002), and indicates these two
hot-Jupiters may have significantly different atmospheric properties.

712.0762 | Probing FSR star cluster candidates in bulge/disk directions with 2MASS
colour-magnitude diagrams | We analyse 20 star cluster candidates projected mostly in the bulge direction
($|\ell|<60^\circ$). The sample contains all candidates in that sector
classified by \citet{FSRcat} with quality flags denoting high probability of
being star clusters. Bulge contamination in the colour-magnitude diagrams
(CMDs) is in general important, while at lower Galactic latitudes disk stars
contribute as well. Properties of the candidates are investigated with 2MASS
CMDs and stellar radial density profiles (RDPs) built with field star
decontaminated photometry. To uncover the nature of the structures we
decontaminate the CMDs from field stars using tools that we previously
developed to deal with objects in dense fields. We confirm in all cases
excesses in the RDPs with respect to the background level, as expected from the
method the candidates were originally selected. CMDs and RDPs taken together

712.0763 | Light-induced rotation of dye-doped liquid crystal droplets | We investigate both theoretically and experimentally the rotational dynamics
of micrometric droplets of dye-doped and pure liquid crystal induced by
circularly and elliptically polarized laser light. The droplets are dispersed
in water and trapped in the focus of the laser beam. Since the optical torque
acting on the molecular director is known to be strongly enhanced in
light-absorbing dye-doped materials, the question arises whether a similar
enhancement takes place also for the overall optical torque acting on the whole
droplets. We searched for such enhancement by measuring and comparing the
rotation speed of dye-doped droplets induced by a laser beam having a
wavelength either inside or outside the dye absorption band, and also comparing
it with the rotation of pure liquid crystal droplets. No enhancement was found,
confirming that photoinduced dye effects are only associated with an internal
exchange of angular momentum between orientational and translational degrees of
freedom of matter. Our result provides also the first direct experimental proof
of the existence of a photoinduced stress tensor in the illuminated dye-doped
liquid crystal. Finally, peculiar photoinduced dynamical effects are predicted
to occur in droplets in which the molecular director is not rigidly locked to
the flow, but so far they could not be observed.

712.0765 | Remarks on the tight-binding model of graphene | We address a simple but fundamental issue arising in the study of graphene,
as well as of other systems that have a crystalline structure with more than
one atom per unit cell. For these systems, the choice of the tight-binding
basis is not unique. For monolayer graphene two bases are widely used in the
literature. While the expectation values of operators describing physical
quantities should be independent of basis, the form of the operators may depend
on the basis, especially in the presence of disorder or of an applied magnetic
field. Using the inappropriate form of certain operators may lead to erroneous
physical predictions. We discuss the two bases used to describe monolayer
graphene, as well as the form of the most commonly used operators in the two
bases. We repeat our analysis for the case of bilayer graphene.

712.0766 | Dust evolution in protoplanetary disks | We investigate the behaviour of dust in protoplanetary disks under the action
of gas drag using our 3D, two-fluid (gas+dust) SPH code. We present the
evolution of the dust spatial distribution in global simulations of planetless
disks as well as of disks containing an already formed planet. The resulting
dust structures vary strongly with particle size and planetary gaps are much
sharper than in the gas phase, making them easier to detect with ALMA than
anticipated. We also find that there is a range of masses where a planet can
open a gap in the dust layer whereas it doesn't in the gas disk. Our dust
distributions are fed to the radiative transfer code MCFOST to compute
synthetic images, in order to derive constraints on the settling and growth of
dust grains in observed disks.

712.0767 | Surface-mediated non-linear optical effects in liquid crystals | We make a phenomenological model of optical two-beam interaction in a model
planar liquid crystal cell. The liquid crystal is subject to homeotropic
anchoring at the cell walls, is surrounded by thin photosensitive layers, and
is subject to a variable potential across the cell. These systems are often
known as liquid crystal photorefractive systems. The interference between the
two obliquely incident beams causes a time-independent periodic modulation in
electric field intensity in the direction transverse to the cell normal. Our
model includes this field phenomenologically by affecting the potential at the
walls of the cell. The transverse periodic surface potential causes spatially
periodic departures from a pure homeotropic texture. The texture modulation
acts as a grating for the incident light. The incident light is both directly
transmitted and also subject to diffraction. The first diffracted beams result
in energy exchange between the beams. We find that the degree of energy
exchange can be strongly sensitive to the mean angle of incidence, the angle
between the beams, and the imposed potential across the cell. We use the model
to speculate about what factors optimize non-linear optical interaction in
liquid crystalline photorefractive systems.

712.0768 | Strange quark mass from Finite Energy QCD sum rules to five loops | The strange quark mass is determined from a new QCD Finite Energy Sum Rule
(FESR) optimized to reduce considerably the systematic uncertainties arising
from the hadronic resonance sector. As a result, the main uncertainty in this
determination is due to the value of $\Lambda_{QCD}$. The correlator of
axial-vector divergences is used in perturbative QCD to five-loop order,
including quark and gluon condensate contributions, in the framework of both
Fixed Order (FOPT), and Contour Improved Perturbation Theory (CIPT). The latter
exhibits very good convergence, leading to a remarkably stable result in the
very wide range $s_0 = 1.0 - 4.0 {GeV}^2$, where $s_0$ is the radius of the
integration contour in the complex energy (squared) plane. The value of the
strange quark mass in this framework at a scale of 2 GeV is $m_s(2 {GeV}) = 95
\pm 5 (111 \pm 6) {MeV}$ for $\Lambda_{QCD} = 420

712.0769 | Towards 3D ultrasound image based soft tissue tracking: a transrectal
ultrasound prostate image alignment system | The emergence of real-time 3D ultrasound (US) makes it possible to consider
image-based tracking of subcutaneous soft tissue targets for computer guided
diagnosis and therapy. We propose a 3D transrectal US based tracking system for
precise prostate biopsy sample localisation. The aim is to improve sample
distribution, to enable targeting of unsampled regions for repeated biopsies,
and to make post-interventional quality controls possible. Since the patient is
not immobilized, since the prostate is mobile and due to the fact that probe
movements are only constrained by the rectum during biopsy acquisition, the
tracking system must be able to estimate rigid transformations that are beyond
the capture range of common image similarity measures. We propose a fast and
robust multi-resolution attribute-vector registration approach that combines
global and local optimization methods to solve this problem. Global
optimization is performed on a probe movement model that reduces the
dimensionality of the search space and thus renders optimization efficient. The
method was tested on 237 prostate volumes acquired from 14 different patients
for 3D to 3D and 3D to orthogonal 2D slices registration. The 3D-3D version of
the algorithm converged correctly in 96.7% of all cases in 6.5s with an
accuracy of 1.41mm (r.m.s.) and 3.84mm (max). The 3D to slices method yielded a
success rate of 88.9% in 2.3s with an accuracy of 1.37mm (r.m.s.) and 4.3mm
(max).

let L be a line bundle on C generated by its global sections. The morphism i:C
-->P(H^0(L))=P is well-defined and i*T is the restriction to C of the tangent
bundle T of the projective space P. Sharpening a theorem by Paranjape, we show
that if deg L>2g-c(C)-1 then i*T is semi-stable, specifying when it is also
stable. We then prove the existence on many curves of a line bundle L of degree
2g-c(C)-1 such that i*T is not semi-stable. Finally, we completely characterize
the (semi-)stability of i*T when C is hyperelliptic.

712.0771 | Magnetic, Chemical and Rotational Properties of the Herbig Ae/Be Binary
System HD 72106 | Recently, strong, globally-ordered magnetic fields have been detected in some
Herbig Ae and Be (HAeBe) stars, suggesting a possible evolutionary connection
to main sequence magnetic chemically peculiar Ap and Bp stars. We have
undertaken a detailed study of the binary system HD 72106, which contains a B9
magnetic primary and a HAeBe secondary, using the ESPaDOnS spectropolarimeter
mounted on the CFHT. A careful analysis of the very young primary reveals that
it has an approximately dipolar magnetic field geometry, strong chemical
peculiarities, and strong surface chemical abundance inhomogeneities. Thus the
primary is very similar to an Ap/Bp star despite having completed less then
1.5% of its main sequence life, and possibly still being on the pre-main
sequence. In contrast, a similar analysis of the secondary reveals solar
chemical abundances and no magnetic field.

712.0772 | 3D SPH simulations of grain growth in protoplanetary disks | We present the first results of the treatment of grain growth in our 3D,
two-fluid (gas+dust) SPH code describing protoplanetary disks. We implement a
scheme able to reproduce the variation of grain sizes caused by a variety of
physical processes and test it with the analytical expression of grain growth
given by Stepinski & Valageas (1997) in simulations of a typical T Tauri disk
around a one solar mass star. The results are in agreement with a turbulent
growing process and validate the method. We are now able to simulate the grain
growth process in a protoplanetary disk given by a more realistic physical
description, currently under development. We discuss the implications of the

712.0774 | Four Zero Neutrino Yukawa Textures in the Minimal Seesaw Framework | We investigate, within the Type I seesaw framework, the physical implications
of zero textures in the Yukawa couplings which generate the neutrino Dirac mass
matrix $m_D$. It is shown that four is the maximal number of texture zeroes
compatible with the observed leptonic mixing and the assumption that no
neutrino mass vanishes. We classify all allowed four-zero textures of $m_D$
into two categories with three classes each. We show that the different
classes, in general, admit CP violation both at low and high energies. We
further present the constraints obtained for low energy physics in each case.
The r\^ ole of these zero textures in establishing a connection between
leptogenesis and low energy data is analysed in detail. It is shown that it is
possible in all cases to completely specify the parameters relevant for
leptogenesis in terms of light neutrino masses and leptonic mixing together

712.0775 | Some nonasymptotic results on resampling in high dimension, I:
Confidence regions, II: Multiple tests | We study generalized bootstrap confidence regions for the mean of a random
vector whose coordinates have an unknown dependency structure. The random
vector is supposed to be either Gaussian or to have a symmetric and bounded
distribution. The dimensionality of the vector can possibly be much larger than
the number of observations and we focus on a nonasymptotic control of the
confidence level, following ideas inspired by recent results in learning
theory. We consider two approaches, the first based on a concentration
principle (valid for a large class of resampling weights) and the second on a
resampled quantile, specifically using Rademacher weights. Several intermediate
results established in the approach based on concentration principles are of
interest in their own right. We also discuss the question of accuracy when
using Monte Carlo approximations of the resampled quantities.

712.0776 | Identification of RR Lyrae Variables in SDSS from Single-Epoch
Photometric and Spectroscopic Observations | We describe a new RR Lyrae identification technique based on out-of-phase
single-epoch photometric and spectroscopic observations contained in SDSS Data
Release 6 (DR-6). This technique detects variability by exploiting the large
disparity between the g-r color and the strength of the hydrogen Balmer lines
when the two observations are made at random phases. Comparison with a large
sample of known variables in the SDSS equatorial stripe (Stripe 82) shows that
the discovery efficiency for our technique is ~85%. Analysis of stars with
multiple spectroscopic observations suggests a similar efficiency throughout
the entire DR-6 sample. We also develop a technique to estimate the average g
apparent magnitude (over the pulsation cycle) for individual RR Lyrae stars,
using the <g-r> for the entire sample and measured colors for each star. The
resulting distances are found to have precisions of ~14%. Finally, we explore
the properties of our DR-6 sample of N = 1087 variables, and recover portions
of the Sagittarius Northern and Southern Stream. Analysis of the distance and
velocity for the Southern Stream are consistent with previously published data
for blue horizontal-branch stars. In a sample near the North Galactic Polar
Cap, we find evidence for the descending leading Northern arm, and a possible
detection of the trailing arm.

712.0777 | T-odd effects in photon-jet production at the Tevatron | The angular distribution in photon-jet production in p \bar{p} -> \gamma jet
X is studied within a generalized factorization scheme taking into account the
transverse momentum of the partons in the initial hadrons. Within this scheme
an anomalously large cos(2\phi) asymmetry observed in the Drell-Yan process
could be attributed to the T-odd, spin and transverse momentum dependent parton
distribution function h_1^{\perp q}(x, p_{\perp}^2). This same function is
expected to produce a cos(2\phi) asymmetry in the photon-jet production cross
section. We give the expression for this particular azimuthal asymmetry, which
is estimated to be smaller than the Drell-Yan asymmetry but still of

712.0778 | A Nearly Scale Invariant Spectrum of Gravitational Radiation from Global
Phase Transitions | Using a large N sigma model approximation we explicitly calculate the power
spectrum of gravitational waves arising from a global phase transition in the
early universe and we confirm that it is scale invariant, implying an
observation of such a spectrum may not be a unique feature of inflation.
Moreover, the predicted amplitude can be over 3 orders of magnitude larger than
the naive dimensional estimate, implying that even a transition that occurs
after inflation may dominate in Cosmic Microwave Background polarization or
other gravity wave signals.
