708.4049 | An analysis of the durations of Swift Gamma-Ray Bursts | We report the systematic analysis of the durations for Swift gamma-ray bursts
(GRBs) and compare the results with those of pre-Swift data. For 95 GRBs with
known redshift, we show that the observed durations have two lognormal
distributions that are clearly divided at $T_{90}\simeq2$ s. This is consistent
with the earlier BATSE results. The intrinsic durations also show a bimodal
distribution but shift systematically toward the smaller value and the
distribution exhibits a narrower width compared with the observed one. We find
that the intrinsic distributions of long GRBs between Swift and pre-Swift are
significantly different particularly in the width and the median value. In
addition, the Swift data exhibit a wider dynamic range of duration. Our present
study not only confirms the spectra of short GRBs are in general harder than
the long GRBs in the observer frame but also shows this trend becomes weaker in
the source frame.

composites prepared by electro-deposition. The ME coupling of Ni-lead zirconate
titanate (PZT)-Ni trilayered structure was measured ranged from1 kHz to 120
kHz. The trilayered composites exhibit high magnetoelectric voltage coefficient
because of good bonding between piezoelectric and magnetostrictive layers. The
maximum magnetoelectric voltage coefficient can be up to 33 V/cm Oe at the
electromechanical resonance frequency. This magnetoelectric effect shows
promising application in transducers for magnetoelectric energy conversion.

708.4051 | On orthostochastic, unistochastic and qustochastic matrices | We introduce qustochastic matrices as the bistochastic matrices arising from
quaternionic unitary matrices by replacing each entry with the square of its
norm. This is the quaternionic analogue of the unistochastic matrices studied
by physicists. We also introduce quaternionic Hadamard matrices and
quaternionic mutually unbiased bases (MUB). In particular we show that the
number of MUB in an n-dimensional quaternionic Hilbert space is at most 2n+1.

708.4052 | Magnetoelectric Effect in Ni-PZT-Ni Cylindrical Layered Composite
Synthesized by Electro-deposition | The magnetoelectric (ME) coupling of cylindrical trilayered composite was
studied in this paper. The Ni-lead zirconate titanate (PZT)-Ni trilayered
cylindrical composite was synthesized by electro-deposition. The maximum ME
voltage coefficient of cylindrical ME composite is 35V/cm Oe, about three times
higher than that of the plate trilayered composite with the same raw materials
and magnetostrictive- piezoelectric phase thickness ratio. The high ME voltage
coefficient of cylindrical composite owes to the self-bound effect of circle.
Moreover, the resulting complex condition can induce a double peak in the field
dependence of ME coefficient.

708.4053 | Origin of Ferromagnetism in nitrogen embedded ZnO:N thin films | Nitrogen embedded ZnO:N films prepared by pulsed laser deposition exhibit
significant ferromagnetism. The nitrogen ions contained in ZnO confirmed by
Secondary Ion Microscopic Spectrum and Raman experiments and the embedded
nitrogen ions can be regarded as defects. According to the experiment results,
a mechanism is proposed based on one of the electrons in the completely filled
d-orbits of Zn that compensates the dangling bonds of nitrogen ions and leads
to a net spin of one half in the Zn orbits. These one half spins strongly
correlate with localized electrons that are captured by defects to form
ferromagnetism. Eventually, the magnetism of nitrogen embedded ZnO:N films
could be described by a bound magnetic polaron model.

parameters of the soft-wall model (originally fixed by observables such as
m_rho) to vary, one finds fits that tend to agree better with F_pi(Q^2). We
also compute the pion charge radius <r_pi^2> for a variety of parameter
choices, and use the values of f^(n)_rho, g_{rho^(n) pi pi} and m^(n)_rho to
observe the saturation of F_pi(0) by rho poles.

708.4055 | Resonant Atom Traps for Electromagnetic Waves | Exitation of atomic levels due to interaction with electromagnetic waves has
been the subject of numerous works, both experimental and theoretical. This
topic became of interest in accelerator physics in relation to high efficiency
charge exchange injection into rings for high beam power applications. Taking
equations of resonant atom-wave interaction equations as a basis, this paper
shows that there exist some interesting phenomena which lead to the existence
of trapped electomagnetic waves (photon traps) in a medium that consists of
atoms with transition frequencies in proximity to the wave frequency. These
traps may exist in random and periodic lattices, and may have very low loss
rate. The atomic medium can serve as an excellent wavegiude or tool to form and
transmit electromagnetic waves for applications to accelerators and to
electromagnetic devices in general, where high pressure gas use is acceptable.
In addition, such traps in gases may accumulate substantial energy for a long
period of time, leading to the possibility of creating objects similar (or
equivalent) to ball lightning.

708.4056 | Renormalization group analysis of resonantly interacting anyons | We formulate a field theory for resonantly interacting anyons, that enables
us to perform a perturbative calculation near the fermionic limit. We derive
renormalization group equations for three-body and four-body couplings at
one-loop order. In addition to two fixed points, we find a limit cycle behavior

708.4059 | Asymptotic Blocking Probabilities in Loss Networks with Subexponential
Demands | The analysis of stochastic loss networks has long been of interest in
computer and communications networks and is becoming important in the areas of
service and information systems. In traditional settings, computing the well
known Erlang formula for blocking probability in these systems becomes
intractable for larger resource capacities. Using compound point processes to
capture stochastic variability in the request process, we generalize existing
models in this framework and derive simple asymptotic expressions for blocking
probabilities. In addition, we extend our model to incorporate reserving
resources in advance. Although asymptotic, our experiments show an excellent

708.4061 | Plasma experiments with relevance for complexity science | The goal of this paper is the identification of the physical processes at the
origin of the nonlinear behavior of a plasma conductor when an external
constraint gradually departs the system from thermal equilibrium. This reveals
the presence of a self-organization scenario whose final product depends on the
magnitude of the applied constraint. At first it appears a complexity whose
stability is ensured by the presence of an electrical double layer. By
increasing the external constraint the complexity transits into an autonomous
state whose existence is related to a rhythmic exchange of matter and energy
with the surrounding environment, sustained and controlled by a proper dynamics
of the double layer. The results are potentially important for developing a
general strategy of nonequilibrium physics, suggesting answers to challenging
problems concerning the mechanism that could explain the appearance of
self-organized complexities in laboratory and nature.

708.4062 | Constraining Dark Energy and Cosmological Transition Redshift with Type
Ia Supernovae | The property of dark energy and the physical reason for acceleration of the
present universe are two of the most difficult problems in modern cosmology.
The dark energy contributes about two-thirds of the critical density of the
present universe from the observations of type-Ia supernova (SNe Ia) and
anisotropy of cosmic microwave background (CMB).The SN Ia observations also
suggest that the universe expanded from a deceleration to an acceleration phase
at some redshift, implying the existence of a nearly uniform component of dark
energy with negative pressure. We use the ``gold'' sample containing 157 SNe Ia
and two recent well-measured additions, SNe Ia 1994ae and 1998aq to explore the
properties of dark energy and the transition redshift. For a flat universe with
the cosmological constant, we measure $\Omega_{M}=0.28_{-0.05}^{+0.04}$, which
is consistent with Riess et al. The transition redshift is
$z_{T}=0.60_{-0.08}^{+0.06}$. We also discuss several dark energy models that
define the $w(z)$ of the parameterized equation of state of dark energy
including one parameter and two parameters ($w(z)$ being the ratio of the
pressure to energy density). Our calculations show that the accurately
calculated transition redshift varies from $z_{T}=0.29_{-0.06}^{+0.07}$ to
$z_{T}=0.60_{-0.08}^{+0.06}$ across these models. We also calculate the minimum
redshift $z_{c}$ at which the current observations need the universe to
accelerate.

708.4064 | Ball Lightning as a Self-organized Complexity | The ball lightning phenomenon is explained in the frame of a
self-organization scenario suggested by experiments performed on the
spontaneously generated complex spherical space charge configuration in plasma.
Originated in a hot plasma, suddenly created in a point where a lightning flash
strikes the Earth surface, the ball lightning appearance proves the ability of
nature to generate, by self-organization, complex structures able to ensure
their own existence by exchange of matter and energy with the surroundings.
Their subsequent evolution depends on the environment where they are born.
Under contemporary Earth conditions the lifetime of such complexities is
relatively short. A similar self-organization mechanism, produced by simple
sparks in the earl Earth's atmosphere (chemically reactive plasma) is suggested

708.4065 | Self-consistent theory of reversible ligand binding to a spherical cell | In this article, we study the kinetics of reversible ligand binding to
receptors on a spherical cell surface using a self-consistent stochastic
theory. Binding, dissociation, diffusion and rebinding of ligands are
incorporated into the theory in a systematic manner. We derive explicitly the
time evolution of the ligand-bound receptor fraction p(t) in various regimes .
Contrary to the commonly accepted view, we find that the well-known
Berg-Purcell scaling for the association rate is modified as a function of
time. Specifically, the effective on-rate changes non-monotonically as a
function of time and equals the intrinsic rate at very early as well as late
times, while being approximately equal to the Berg-Purcell value at
intermediate times. The effective dissociation rate, as it appears in the
binding curve or measured in a dissociation experiment, is strongly modified by
rebinding events and assumes the Berg-Purcell value except at very late times,
where the decay is algebraic and not exponential. In equilibrium, the ligand
concentration everywhere in the solution is the same and equals its spatial
mean, thus ensuring that there is no depletion in the vicinity of the cell.
Implications of our results for binding experiments and numerical simulations
of ligand-receptor systems are also discussed.

708.4066 | On the "mystery" of differential negative resistance | Investigating the causes of the nonlinear behavior of a gaseous conductor we
identified the presence of two states of the complex space charge configuration
self-assembled in front of the anode. These states correspond to two levels of
self-organization from which the first one is related to spatial pattern
whereas the second one to spatiotemporal pattern. Their emergence through two
kinds of instabilities produced for two critical distances from thermodynamic
equilibrium is emphasized in the current voltage characteristic as an S-shaped,
respectively Z-shaped bistability. Their presence attributes to the gaseous

708.4069 | Bishop's Theorem and Differentiability of a subspace of $C_b(K)$ | Let $K$ be a Hausdorff space and $C_b(K)$ be the Banach algebra of all
complex bounded continuous functions on $K$. We study the G\^{a}teaux and
Fr\'echet differentiability of subspaces of $C_b(K)$. Using this, we show that
the set of all strong peak functions in a nontrivial separating separable
subspace $H$ of $C_b(K)$ is a dense $G_\delta$ subset of $H$, if $K$ is
compact. This gives a generalized Bishop's theorem, which says that the closure
of the set of strong peak point for $H$ is the smallest closed norming subset
of $H$. The classical Bishop's theorem was proved for a separating subalgebra
$H$ and a metrizable compact space $K$.
In the case that $X$ is a complex Banach space with the Radon-Nikod\'ym
property, we show that the set of all strong peak functions in $A_b(B_X)=\{f\in
C_b(B_X) : f|_{B_X^\circ} {is holomorphic}\}$ is dense. As an application, we
show that the smallest closed norming subset of $A_b(B_X)$ is the closure of
the set of all strong peak points for $A_b(B_X)$. This implies that the norm of
$A_b(B_X)$ is G\^{a}teaux differentiable on a dense subset of $A_b(B_X)$, even
though the norm is nowhere Fr\'echet differentiable when $X$ is nontrivial. We
also study the denseness of norm attaining holomorphic functions and
polynomials. Finally we investigate the existence of numerical Shilov boundary.
| math.FA | let k be a hausdorff space and c_bk be the banach algebra of all complex bounded continuous functions on k we study the gateaux and frechet differentiability of subspaces of c_bk using this we show that the set of all strong peak functions in a nontrivial separating separable subspace h of c_bk is a dense g_delta subset of h if k is compact this gives a generalized bishops theorem which says that the closure of the set of strong peak point for h is the smallest closed norming subset of h the classical bishops theorem was proved for a separating subalgebra h and a metrizable

for m \geq 2, by providing an upper bound that agrees with the lower bound in
\cite{BonnafePfeiffer2006}. The bound is obtained by showing that the length of
the longest path in the quiver of the descent algebra of D_{2m+1} is at most
m+1. To achieve this bound, the geometric approach to the descent algebra is
used, in which the descent algebra of a finite Coxeter group is identified with
an algebra associated to the reflection arrangement of the group.

708.4071 | Shape demagnetization effect on layered magnetoelectric composites | Magnetoelectric (ME) voltage coefficient was always considered independent on
in-plane shape of plate layered magnetostrictive-piezoelectric composites due
to the oversimplification in ME theoretical models. In this article, we present
that in fact the ME voltage coefficient is largely dependent on the in-plane
shape owing to shape demagnetization effect on magnetostrictivity. Theoretical
analysis and experimental results both indicate that ME voltage coefficient
changes notably with the variation of in-plane sizes (length and width) of
layered ME properties. ME coefficient increases with the rise of in-plane
sizes, and different aspect ratio will also result in different ME coefficient.

708.4072 | Autoionization of spin-polarized metastable helium in tight anisotropic
harmonic traps | Spin-dipole mediated interactions between tightly confined metastable helium
atoms couple the spin-polarized quintet ${}^{5}\Sigma^{+}_{g}$ state to the
singlet ${}^{1}\Sigma^{+}_{g}$ state from which autoionization is highly
probable, resulting in finite lifetimes for the trap eigenstates. We extend our
earlier study on spherically symmetric harmonic traps to the interesting cases
of axially symmetric anisotropic harmonic traps and report results for the
lowest 10 states in "cigar-like" and "pancake-like" traps with average
frequencies of 100 kHz and 1 MHz. We find that there is a significant
suppression of ionization, and subsequent increase in lifetimes, at trap aspect
ratios $A=p/q$, where $p$ and $q$ are integers, for those states that are
degenerate in the absence of collisions or spin-dipole interactions.

708.4076 | Holder stability of diffeomorphisms | We prove that a $C^2$ diffeomorphism $f$ of a compact manifold $M$ satisfies
Axiom A and the strong transversality condition if and only if it is H\"{o}lder
stable, that is, any $C^1$ diffeomorphism $g$ of $M$ sufficiently $C^1$ close

708.4078 | Optomechanical trapping and cooling of partially transparent mirrors | We consider the radiative trapping and cooling of a partially transmitting
mirror suspended inside an optical cavity, generalizing the case of a perfectly
reflecting mirror previously considered [M. Bhattacharya and P. Meystre, Phys.
Rev. Lett. \textbf{99}, 073601 (2007)]. This configuration was recently used in
an experiment to cool a nanometers-thick membrane [Thompson \textit{et al.},
arXiv:0707.1724v2, 2007]. The self-consistent cavity field modes of this system
depend strongly on the position of the middle mirror, leading to important
qualitative differences in the radiation pressure effects: in one case, the
situation is similar that of a perfectly reflecting middle mirror, with only
minor quantitative modifications. In addition, we also identify a range of
mirror positions for which the radiation-mirror coupling becomes purely
dispersive and the back-action effects that usually lead to cooling are absent,
although the mirror can still be optically trapped. The existence of these two
regimes leads us to propose a bichromatic scheme that optimizes the cooling and
trapping of partially transmissive mirrors.

708.4079 | GMRT Low Frequency Observations of Extrasolar Planetary Systems | Extrasolar planets are expected to emit detectable low frequency radio
emission. In this paper we present results from new low frequency observations
of two extrasolar planetary systems (Epsilon Eridani and HD 128311) taken at
150 MHz with the Giant Metrewave Radio Telescope (GMRT). These two systems have
been chosen because the stars are young (with ages < 1 Gyr) and are likely to
have strong stellar winds, which will increase the expected radio flux. The
planets are massive (presumably) gas giant planets in longer period orbits, and
hence will not be tidally locked to their host star (as is likely to be the
case for short period planets) and we would expect them to have a strong
planetary dynamo and magnetic field. We do not detect either system, but are
able to place tight upper limits on their low frequency radio emission, at
levels comparable to the theoretical predictions for these systems. From these
observations we have a 2.5sigma limit of 7.8 mJy for Epsilon Eri and 15.5 mJy
for HD 128311. In addition, these upper limits also provide limits on the low
frequency radio emission from the stars themselves. These results are discussed
and also the prospects for the future detection of radio emission from
extrasolar planets.
| astro-ph | extrasolar planets are expected to emit detectable low frequency radio emission in this paper we present results from new low frequency observations of two extrasolar planetary systems epsilon eridani and hd 128311 taken at 150 mhz with the giant metrewave radio telescope gmrt these two systems have been chosen because the stars are young with ages 1 gyr and are likely to have strong stellar winds which will increase the expected radio flux the planets are massive presumably gas giant planets in longer period orbits and hence will not be tidally locked to their host star as is likely to be the case for short period planets and we would expect them to have a strong planetary dynamo and magnetic field we do not detect either system but are able to place tight upper limits on their low frequency radio emission at levels comparable to the theoretical predictions for these systems from these observations we have a 25sigma limit of 78 mjy for epsilon eri and 155 mjy for hd

708.4081 | A recursive online algorithm for the estimation of time-varying ARCH
parameters | In this paper we propose a recursive online algorithm for estimating the
parameters of a time-varying ARCH process. The estimation is done by updating
the estimator at time point $t-1$ with observations about the time point $t$ to
yield an estimator of the parameter at time point $t$. The sampling properties
of this estimator are studied in a non-stationary context -- in particular,
asymptotic normality and an expression for the bias due to non-stationarity are
established. By running two recursive online algorithms in parallel with
different step sizes and taking a linear combination of the estimators, the

| math.ST stat.TH | in this paper we propose a recursive online algorithm for estimating the parameters of a timevarying arch process the estimation is done by updating the estimator at time point t1 with observations about the time point t to yield an estimator of the parameter at time point t the sampling properties of this estimator are studied in a nonstationary context in particular asymptotic normality and an expression for the bias due to nonstationarity are established by running two recursive online algorithms in parallel with different step sizes and taking a linear combination of the estimators the rate of convergence can be improved for parameter curves from holder classes of order between 1 and 2 | [['in', 'this', 'paper', 'we', 'propose', 'a', 'recursive', 'online', 'algorithm', 'for', 'estimating', 'the', 'parameters', 'of', 'a', 'timevarying', 'arch', 'process', 'the', 'estimation', 'is', 'done', 'by', 'updating', 'the', 'estimator', 'at', 'time', 'point', 't1', 'with', 'observations', 'about', 'the', 'time', 'point', 't', 'to', 'yield', 'an', 'estimator', 'of', 'the', 'parameter', 'at', 'time', 'point', 't', 'the', 'sampling', 'properties', 'of', 'this', 'estimator', 'are', 'studied', 'in', 'a', 'nonstationary', 'context', 'in', 'particular', 'asymptotic', 'normality', 'and', 'an', 'expression', 'for', 'the', 'bias', 'due', 'to', 'nonstationarity', 'are', 'established', 'by', 'running', 'two', 'recursive', 'online', 'algorithms', 'in', 'parallel', 'with', 'different', 'step', 'sizes', 'and', 'taking', 'a', 'linear', 'combination', 'of', 'the', 'estimators', 'the', 'rate', 'of', 'convergence', 'can', 'be', 'improved', 'for', 'parameter', 'curves', 'from', 'holder', 'classes', 'of', 'order', 'between', '1', 'and', '2']] | [-0.09287921249868528, 0.06625602017549936, -0.10558701597415564, 0.05447861620104321, -0.023181872679280083, -0.13522012802167682, 0.0652969928158104, 0.40495837682433294, -0.28764812599279377, -0.3078486229979286, 0.15968379980410663, -0.21792089499598533, -0.11275856592896673, 0.19790815365941902, -0.06621294627946459, 0.09003646035368244, 0.033047336484550646, 0.01946557093444362, -0.0927085235690404, -0.2865969241441538, 0.27902255272656157, 0.07684524225381513, 0.2425957167798882, -0.046300581419481, 0.1295880876775635, 0.034589484313568265, -0.058115549700073245, 0.029230183823720404, -0.14364770285196996, 0.07543047581260141, 0.2637013797729946, 0.11231334401261911, 0.33986695540513384, -0.34672711788586813, -0.1699992170181583, 0.12830960831866323, 0.1353770889782984, 0.08226281580139409, -0.013936158218584432, -0.25749688231582313, 0.09456146863011415, -0.117771383236048, -0.09978612883653688, -0.039990148964550415, -0.006736053754330466, 0.04485320944437071, -0.37086759372859407, 0.09927512770682051, 0.08300114052141444, 0.07846003707923126, -0.02998917598865534, -0.12007323119854718, 0.04655802783376554, 0.11214583257638049, 0.09150320446101352, 0.00840938085150954, 0.08070923881033402, -0.11142058091609854, -0.1273427345512206, 0.28332822419408904, -0.07166742629334821, -0.19151691891449063, 0.1397144579402122, -0.12197309132796108, -0.13784837490968863, 0.12923382824335836, 0.2145909275491967, 0.11405840213002082, -0.1876919488095793, 0.10987967162713687, 0.010366273880527731, 0.11316322833845972, 0.05418637463528859, -0.0022582492276437974, 0.1229784393339957, 0.17741346858204915, 0.1100957432492195, 0.14193389840473078, -0.1173138529340034, -0.06821371058998793, -0.31203933882020546, -0.13771991582848786, -0.19520599070707695, -0.011100420787554691, -0.19447584355440453, -0.14901616065681242, 0.40838368189635504, 0.1591579141381213, 0.2287282144585461, 0.12335919407441427, 0.28382218776172713, 0.1541758295426374, 0.0024889686488007243, 0.13200791679290041, 0.1833779851460764, 0.0948423098143713, 0.08651694573314958, -0.20516833263702625, 0.14251742441730017, 0.08754244678563912] |

sp\'ecifiques de conception et solutions potentielles | The observation that novice users seldom consult online help was made over
twenty years ago. This observation still holds nowadays, although online help
to the use of software for the general public has greatly improved in usability
during this period. The paper first demonstrates the necessity of online help
to the use of new software whatever the transparency of the user interface, as
whether online help systems are meant to compensate for interface design
weaknesses or actually do provide necessary assistance to the discovery of a
new software package functionalities is still an unsolved issue. The discussion
relies on results of empirical and experimental studies and theoretical
arguments. In the second part, we analyse the specific difficulties raised by
the design of effective online help systems for current software intended for
the general public so as to try and understand the reluctance of novice users
to use online help. In the last part, we present and discuss the possible
contributions of various approaches to solving this issue. Recent interaction
paradigms and techniques are considered, such as, static and dynamic
personalisation, contextual online help and new forms of multimodality.

708.4083 | Metal Abundance Properties of M81 Globular Cluster System | This paper is the third in the series of papers on M81 globular clusters. In
this paper, we present spatial and metal abundance properties of 95 M81
globular clusters, which comprise nearly half of all the M81 globular cluster
system. These globular clusters are divided into two M81 metallicity groups by
a KMM test. Our results show that, the metal-rich clusters did not demonstrate
a centrally concentrated spatial distribution as ones in M31, and metal-poor
clusters tend to be less spatially concentrated. In other words, the
distribution of the metal-rich clusters in M81 is not very similar to that of
M31. Most of the metal-rich clusters distribute at projected radii of 4-8 kpc.
It is also noted that the metal-rich clusters distribute within the inner 20
kpc, and the metal-poor ones do out to radii of ~40 kpc. Like our Galaxy and
M31, the metallicity distribution of globular clusters in M81 along
galactocentric radius suggests that some dissipation occurred during the
formation of the globular cluster system, i.e. smooth, pressure-supported
collapse models of galaxies are unlikely to produce such radial distribution of
metallicity presented in this paper. There is not evident correlation between
globular cluster luminosity and metallicity in M81 globular clusters. The
overwhelming conclusion of this paper seems to be that a more complete and
thorough cluster search is needed in M81.

different methods of MQ NMR. One of them is based on the measurement of the

time of order T2 after the MQ NMR experiment. The other method uses an
additional resonance 45^0 -pulse after the preparation period of the standard

faster in such experiments than in the usual MQ NMR experiments and can be used
for the investigation of many-spin dynamics of nuclear spins in solids.

708.4086 | Non-Markovian hole spin kinetics in $p$-type GaAs quantum wells | Based on fully microscopic kinetic spin Bloch equation approach, we show the
non-Markovian effect in spin dephasing of heavy holes in $p$-type GaAs quantum
wells. The non-Markovian effect manifests itself in spin dephasing when the
mean spin precession time is shorter than the momentum relaxation time. The
spin dephasing becomes slower when the non-Markovian effect is important.

708.4087 | Higher loop renormalization of fermion bilinear operators | We compute the two-loop renormalization functions, in the RI' scheme, of
local bilinear quark operators $\bar\psi\Gamma\psi$, where $\Gamma$ denotes the
Scalar and Pseudoscalar Dirac matrices, in the lattice formulation of QCD. We
consider both the flavor non-singlet and singlet operators; the latter, in the
scalar case, leads directly to the two-loop fermion mass renormalization,
$Z_m$.
As a prerequisite for the above, we also compute the quark field
renormalization, $Z_\psi$, up to two loops.
We use the clover action for fermions and the Wilson action for gluons. Our
results are given as a polynomial in $c_{SW}$, in terms of both the
renormalized and bare coupling constant, in the renormalized Feynman gauge. We
also confirm the 1-loop renormalization functions, for generic gauge.
A longer write-up of the present work, including the conversion of our
results to the MSbar scheme and a generalization to arbitrary fermion
representations, can be found in arXiv:0707.2906 .

rare decays B -> h(*) nu nubar\ove, where h(*) stands for a light meson. A data
sample of 535 million BBbar pairs collected with the Belle detector at the KEKB
e+e- collider is used. We find a signal with a significance of 5.2 standard
deviations on B0 -> D*- tau+ nu and measure the branching fraction to be 2.02
+0.40/-0.37 (stat.) +- 0.37 (syst.)%. No significant signal is observed for B
-> h(*) nu nubar decays and we set upper limits on the branching fractions at
90% confidence level. The limits on B0 -> K*0 nu nubar and B+ -> K+ nu nubar
decays are more stringent than the previous constraints, while the first

708.4092 | Interactions of Non-Abelian Global Strings | Non-Abelian global strings are expected to form during the chiral phase
transition. They have orientational zero modes in the internal space,
associated with the vector-like symmetry SU(N)_{L+R} broken in the presence of
strings. The interaction among two parallel non-Abelian global strings is
derived for general relative orientational zero modes, giving a non-Abelian
generalization of the Magnus force. It is shown that when the orientations of
the strings are the same, the repulsive force reaches the maximum, whereas when
the relative orientation becomes the maximum, no force exists between the
strings. For the Abelian case we find a finite volume correction to the known

708.4093 | Limiting distributions of curves under geodesic flow on hyperbolic
manifolds | We consider the evolution of a compact segment of an analytic curve on the
unit tangent bundle of a finite volume hyperbolic $n$-manifold under the
geodesic flow. Suppose that the curve is not contained in a stable leaf of the
flow. It is shown that under the geodesic flow, the normalized parameter
measure on the curve gets asymptotically equidistributed with respect to the
normalized natural Riemannian measure on the unit tangent bundle of a closed
totally geodesically immersed submanifold.
Moreover, if this immersed submanifold is a proper subset, then a lift of the
curve to the universal covering space $T^1(H^n)$ is mapped into a proper
subsphere of the ideal boundary sphere $\partial H^n$ under the visual map.
This proper subsphere can be realized as the ideal boundary of an isometrically
embedded hyperbolic subspace in $H^n$ covering the closed immersed submanifold.
In particular, if the visual map does not send a lift of the curve into a
proper subsphere of $\partial H^n$, then under the geodesic flow the curve gets
asymptotically equidistributed on the unit tangent bundle of the manifold with
respect to the normalized natural Riemannian measure.
The proof uses dynamical properties of unipotent flows on finite volume
homogeneous spaces of SO(n,1).

708.4094 | A note on the measurement of phase space observables with an eight-port
homodyne detector | It is well known that the Husimi Q-function of the signal field can actually
be measured by the eight-port homodyne detection technique, provided that the
reference beam (used for homodyne detection) is a very strong coherent field so
that it can be treated classically. Using recent rigorous results on the
quantum theory of homodyne detection observables, we show that any phase space
observable, and not only the Q-function, can be obtained as a high amplitude

| quant-ph | it is well known that the husimi qfunction of the signal field can actually be measured by the eightport homodyne detection technique provided that the reference beam used for homodyne detection is a very strong coherent field so that it can be treated classically using recent rigorous results on the quantum theory of homodyne detection observables we show that any phase space observable and not only the qfunction can be obtained as a high amplitude limit of the signal observable actually measured by an eightport homodyne detector the proof of this fact does not involve any classicality assumption | [['it', 'is', 'well', 'known', 'that', 'the', 'husimi', 'qfunction', 'of', 'the', 'signal', 'field', 'can', 'actually', 'be', 'measured', 'by', 'the', 'eightport', 'homodyne', 'detection', 'technique', 'provided', 'that', 'the', 'reference', 'beam', 'used', 'for', 'homodyne', 'detection', 'is', 'a', 'very', 'strong', 'coherent', 'field', 'so', 'that', 'it', 'can', 'be', 'treated', 'classically', 'using', 'recent', 'rigorous', 'results', 'on', 'the', 'quantum', 'theory', 'of', 'homodyne', 'detection', 'observables', 'we', 'show', 'that', 'any', 'phase', 'space', 'observable', 'and', 'not', 'only', 'the', 'qfunction', 'can', 'be', 'obtained', 'as', 'a', 'high', 'amplitude', 'limit', 'of', 'the', 'signal', 'observable', 'actually', 'measured', 'by', 'an', 'eightport', 'homodyne', 'detector', 'the', 'proof', 'of', 'this', 'fact', 'does', 'not', 'involve', 'any', 'classicality', 'assumption']] | [-0.10468485063341047, 0.16431934952071264, -0.14983781780667452, 0.09046872510997654, -0.04293706644402475, -0.17512136767143194, 0.03515234446195809, 0.38709127768037876, -0.23844198061970576, -0.27062908491613913, 0.09547163260511446, -0.21617794172762303, -0.1601917779367721, 0.267917943146669, -0.06034266505371399, 0.09675956895688967, 0.10690368150303863, 0.06448700280422914, -0.03265580758262349, -0.21989612314346418, 0.2663081536991332, 0.0908234608680371, 0.2983120248310876, 0.026602715301346416, 0.14038389371185356, 0.05097895409265647, 0.005440953814861726, 0.051596596426917336, -0.05643270853390128, 0.011423020188848734, 0.2697615976877777, 0.19261203140343483, 0.18423260843419298, -0.3684297056906686, -0.22080266583064684, 0.17377022759423458, 0.13328964444624536, 0.1512643683711257, -0.02547168135476698, -0.3798806116517101, 0.028165994706202527, -0.15815856911203996, -0.07890358217516724, -0.12329452005880219, -0.06224203933914173, 0.0009154408447900597, -0.2660927920678288, 0.05897138021620257, 0.06091126104061283, -0.0024090680027646677, 0.021203181297727386, -0.04471920763275453, 0.01444044029245115, 0.07801838518519487, -0.040803413852403055, 0.06632697364144331, 0.17360580869598732, -0.13164350245271486, -0.15223761527247878, 0.30820915716871317, -0.11375329133161173, -0.209308587499343, 0.13268526080207024, -0.1900764611473649, -0.08732752314512143, 0.15103177268210113, 0.05435475977897948, 0.1364555429591208, -0.13508987335526212, 0.039005191844046994, -0.05666937280389271, 0.23735429357965382, 0.0700669226388694, 0.08826976595268281, 0.18442508734659321, 0.07791943161757853, 0.08744000733773015, 0.095369003001572, -0.11368150116010968, -0.03802891940410648, -0.37231555109729575, -0.14006757755687801, -0.29218297542966143, 0.060630441638843006, -0.034494619189175936, -0.13569110910389193, 0.3344153263606131, 0.14704085890754906, 0.15851561667882286, 0.013015217085996149, 0.36778051460789024, 0.20611801100015753, 0.07925473062834722, -0.0028827717356687908, 0.37595697511367654, 0.13151424000400821, 0.05696116353157071, -0.1960567509784002, 0.11043931971118805, 0.029116172177184905] |

708.4096 | Non-Abelian Strings in High Density QCD: Zero Modes and Interactions | The most fundamental strings in high density color superconductivity are the
non-Abelian semi-superfluid strings which have color gauge flux tube but behave
as superfluid vortices in the energetic point of view. We show that in addition
to the usual translational zero modes, these vortices have normalizable
orientational zero modes in the internal space, associated with the
color-flavor locking symmetry broken in the presence of the strings. The
interaction among two parallel non-Abelian semi-superfluid strings is derived
for general relative orientational zero modes to show the universal repulsion.
This implies that the previously known superfluid vortices, formed by
spontaneously broken U(1)_B, are unstable to decay. Moreover, our result proves
the stability of color superconductors in the presence of external color gauge
fields.

708.4097 | On dynamical smash product | In the theory of dynamical Yang-Baxter equation, with any Hopf algebra $H$
and a certain $H$-module and $H$-comodule algebra $L$ (base algebra) one
associates a monoidal category. Given an algebra $A$ in that category, one can
construct an associative algebra $A\rtimes L$, which is a generalization of the
ordinary smash product when $A$ is an ordinary $H$-algebra. We study this
"dynamical smash product" and its modules induced from one-dimensional

708.4098 | Hybrid Curvatons from Broken Symmetry | We present a new general mechanism for generating curvature perturbations
after inflation. Our model is based on the simple assumption that a field that
starts to oscillate after inflation has a potential characterized by an
underlying global symmetry that is slightly or badly broken. Inhomogeneous
preheating occurs due to the oscillation with the broken symmetry. Unlike the
traditional curvaton model, we will not identify the curvaton with the
oscillating field. The curvaton is identified with the preheat field that could
be either a scalar, vector, or fermionic field. We introduce an explicit mass
term for the curvaton, which is important for later evolution and the decay.
Our present model represents the simplest example of the hybrid of the
curvatons and inhomogeneous preheating.

quantum dot system | We present a physical scheme for implementing quantum phase estimation via
weakly coupled double quantum-dot molecules embedded in a microcavity. During
the same process of implementation, we can also realize the calibration of a
timepiece based on the estimated phase. We use the electron-hole pair states in
coupled double quantum-dot molecules to encode quantum information, where the
requirement that two quantum dots are exactly identical is not necessary. Our
idea can also be generalized to other systems, such as atomic, trapped ion and
linear optics system.

708.4103 | Reentrant transitions of Ising-Heisenberg ferromagnet on a triangular
lattice with diamond-like decorations | The mixed spin-1/2 and spin-1 Ising-Heisenberg ferromagnet on the decorated
triangular lattice consisting of inter-connected diamonds is investigated
within the framework of an exact decoration-iteration mapping transformation.
It is shown that the diamond-like decoration by a couple of the Heisenberg

708.4106 | Biexciton stability in carbon nanotubes | We have applied the quantum Monte Carlo method and tight-binding modelling to
calculate the binding energy of biexcitons in semiconductor carbon nanotubes
for a wide range of diameters and chiralities. For typical nanotube diameters
we find that biexciton binding energies are much larger than previously

708.4107 | The variable mass loss of the AGB star WX Psc as traced by the CO J=1-0
through 7-6 lines and the dust emission | Low and intermediate mass stars lose a significant fraction of their mass
through a dust-driven wind during the Asymptotic Giant Branch (AGB) phase.
Recent studies show that winds from late-type stars are far from being smooth.
Mass-loss variations occur on different time scales, from years to tens of
thousands of years. The variations appear to be particularly prominent towards
the end of the AGB evolution. The occurrence, amplitude and time scale of these
variations are still not well understood.
The goal of our study is to gain insight into the structure of the
circumstellar envelope (CSE) of WX Psc and map the possible variability of the
late-AGB mass-loss phenomenon.
We have performed an in-depth analysis of the extreme infrared AGB star WX
Psc by modeling (1) the CO J=1-0 through 7-6 rotational line profiles and the
full spectral energy distribution (SED) ranging from 0.7 to 1300 micron. We
hence are able to trace a geometrically extended region of the CSE.
Both mass-loss diagnostics bear evidence of the occurrence of mass-loss
modulations during the last ~2000 yr. In particular, WX Psc went through a high
mass-loss phase (Mdot~5e-5 Msun/yr) some 800 yr ago. This phase lasted about
600 yr and was followed by a long period of low mass loss (Mdot~5e-8 Msun/yr).
The present day mass-loss rate is estimated to be ~6e-6 Msun/yr.
The AGB star WX Psc has undergone strong mass-loss rate variability on a time
scale of several hundred years during the last few thousand years. These
variations are traced in the strength and profile of the CO rotational lines
and in the SED. We have consistently simulated the behaviour of both tracers
using radiative transfer codes that allow for non-constant mass-loss rates.

708.4108 | Polynomial identities and noncommutative versal torsors | To any cleft Hopf Galois object, i.e., any algebra H[t] obtained from a Hopf
algebra H by twisting its multiplication with a two-cocycle t, we attach two
"universal algebras" A(H,t) and U(H,t). The algebra A(H,t) is obtained by
twisting the multiplication of H with the most general two-cocycle u formally
cohomologous to t. The cocycle u takes values in the field of rational
functions on H. By construction, A(H,t) is a cleft H-Galois extension of a
"big" commutative algebra B(H,t). Any "form" of H[t] can be obtained from
A(H,t) by a specialization of B(H,t) and vice versa. If the algebra H[t] is
simple, then A(H,t) is an Azumaya algebra with center B(H,t). The algebra
U(H,t) is constructed using a general theory of polynomial identities that we
set up for arbitrary comodule algebras; it is the universal comodule algebra in
which all comodule algebra identities of H[t] are satisfied. We construct an
embedding of U(H,t) into A(H,t); this embedding maps the center Z(H,t) of
U(H,t) into B(H,t) when the algebra H[t] is simple. In this case, under an
additional assumption, A(H,t) is isomorphic to B(H,t) \otimes_{Z(H,t)} U(H,t),
thus turning A(H,t) into a central localization of U(H,t). We work out these
constructions in full detail for the four-dimensional Sweedler algebra.

708.411 | The effect of a planet on the dust distribution in a 3D protoplanetary
disk | Aims: We investigate the behaviour of dust in protoplanetary disks under the
action of gas drag in the presence of a planet. Our goal is twofold: to
determine the spatial distribution of dust depending on grain size and planet
mass, and therefore to provide a framework for interpretation of coming
observations and future studies of planetesimal growth. Method: We numerically
model the evolution of dust in a protoplanetary disk using a two-fluid (gas +
dust) Smoothed Particle Hydrodynamics (SPH) code, which is non-self-gravitating
and locally isothermal. The code follows the three dimensional distribution of
dust in a protoplanetary disk as it interacts with the gas via aerodynamic
drag. In this work, we present the evolution of a minimum mass solar nebula
(MMSN) disk comprising 1% dust by mass in the presence of an embedded planet.
We run a series of simulations which vary the grain size and planetary mass to
see how they affect the resulting disk structure. Results: We find that gap
formation is much more rapid and striking in the dust layer than in the gaseous
disk and that a system with a given stellar, disk and planetary mass will have
a completely different appearance depending on the grain size. For low mass
planets in our MMSN disk, a gap can open in the dust disk while not in the gas
disk. We also note that dust accumulates at the external edge of the planetary
gap and speculate that the presence of a planet in the disk may enhance the
formation of a second planet by facilitating the growth of planetesimals in
this high density region.

708.4111 | Full Spectrum Diffused and Beamed Solar Energy Application Using Optical
Fibre | Existing solar energy application systems use small fraction of full spectrum
of solar energy. So attempts are made to show how full spectrum solar energy
can be used for diffused and beamed form of incident solar energy. Luminescent
Solar Concentrator (LSC) principle with optical fibre in diffused sun light and
dielectric mirror separation technique with optical fibre in beamed form are
discussed. Comparison of both the cases are done.

708.4112 | Phase coherence and extreme self phase modulation | I study how pulse to pulse phase coherence in a pulse train can survive
super-broadening by extreme self phase modulation (SPM). Such pulse trains have
been used in phase self-stabilizing schemes as an alternative to using a
feedback process. However, such super-broadened pulses have undergone
considerable distortion, and it is far from obvious that they necessarily
retain any useful phase information. I propose measures of phase coherence
(i.e. supercontinuum coherence) applicable to such pulse trains, and use them
to analyze numerical simulations comparable to self-stabilization experiments.

708.4114 | Group theoretical construction of mutually unbiased bases in Hilbert
spaces of prime dimensions | Mutually unbiased bases in Hilbert spaces of finite dimensions are closely
related to the quantal notion of complementarity. An alternative proof of
existence of a maximal collection of N+1 mutually unbiased bases in Hilbert
spaces of prime dimension N is given by exploiting the finite Heisenberg group
(also called the Pauli group) and the action of SL(2,Z_N) on finite phase space
Z_N x Z_N implemented by unitary operators in the Hilbert space. Crucial for
the proof is that, for prime N, Z_N is also a finite field.

determined for spectator fragmentation, following collisions of 197Au with
targets ranging from C to Au at incident energies of 600 and 1000 MeV per

observed which coincides with the transition from residue formation to
multi-fragment production, suggesting a chemical freeze-out prior to thermal

708.4116 | Dynamical SUSY Breaking in Intersecting Brane Models | We present a simple mechanism by which supersymmetry can be dynamically
broken in intersecting brane models, naturally generating an exponentially
small scale. Rather than utilize either non-Abelian gauge dynamics or

708.4118 | Transformation of Morphology and Luminosity Classes of the SDSS Galaxies | We present a unified picture on the evolution of galaxy luminosity and
morphology. Galaxy morphology is found to depend critically on the local
environment set up by the nearest neighbor galaxy in addition to luminosity and
the large scale density. When a galaxy is located farther than the virial
radius from its closest neighbor, the probability for the galaxy to have an
early morphological type is an increasing function only of luminosity and the
local density due to the nearest neighbor ($\rho_n$). The tide produced by the
nearest neighbor is thought to be responsible for the morphology transformation
toward the early type at these separations. When the separation is less than
the virial radius, i.e. when $\rho_n > \rho_{\rm virial}$, its morphology
depends also on the neighbor's morphology and the large-scale background
density over a few Mpc scales ($\rho_{20}$) in addition to luminosity and
$\rho_n$. The early type probability keeps increasing as $\rho_n$ increases if
its neighbor is an early type. But the probability decreases as $\rho_n$
increases when the neighbor is a late type. The cold gas streaming from the
late type neighbor can be the reason for the morphology transformation toward
late type. The overall early-type fraction increases as $\rho_{20}$ increases
when $\rho_n > \rho_{\rm virial}$. This can be attributed to the hot halo gas
of the neighbor which is confined by the pressure of the ambient medium held by
the background mass. We have also found that galaxy luminosity depends on
$\rho_n$, and that the isolated bright galaxies are more likely to be recent
merger products. We propose a scenario that a series of morphology and
luminosity transformation occur through distant interactions and mergers, which
results in the morphology--luminosity--local density relation.

708.4119 | The early spectral evolution of SN 2004dt | Aims. We study the optical spectroscopic properties of Type Ia Supernova (SN
Ia) 2004dt, focusing our attention on the early epochs.
Methods. Observation triggered soon after the SN 2004dt discovery allowed us
to obtain a spectrophotometric coverage from day -10 to almost one year (~353
days) after the B band maximum. Observations carried out on an almost daily
basis allowed us a good sampling of the fast spectroscopic evolution of SN
2004dt in the early stages. To obtain this result, low-resolution, long-slit
spectroscopy was obtained using a number of facilities.
Results. This supernova, which in some absorption lines of its early spectra
showed the highest degree of polarization ever measured in any SN Ia, has a
complex velocity structure in the outer layers of its ejecta. Unburnt oxygen is
present, moving at velocities as high as ~16,700 km/s, with some
intermediate-mass elements (Mg, Si, Ca) moving equally fast. Modeling of the
spectra based on standard density profiles of the ejecta fails to reproduce the
observed features, whereas enhancing the density of outer layers significantly
improves the fit. Our analysis indicates the presence of clumps of
high-velocity, intermediate-mass elements in the outermost layers, which is
also suggested by the spectropolarimetric data.

708.412 | Theoretical model atmosphere spectra used for the calibration of
infrared instruments | One of the key ingredients in establishing the relation between input signal
and output flux from a spectrometer is accurate determination of the
spectrophotometric calibration. In the case of spectrometers onboard
satellites, the accuracy of this part of the calibration pedigree is ultimately
linked to the accuracy of the set of reference SEDs that the spectrophotometric
calibration is built on. In this paper, we deal with the spectrophotometric
calibration of infrared (IR) spectrometers onboard satellites in the 2 to 200
micron range. We aim at comparing the different reference SEDs used for the IR
spectrophotometric calibration. The emphasis is on the reference SEDs of
stellar standards with spectral type later than A0, with special focus on the
theoretical model atmosphere spectra. Using the MARCS model atmosphere code,
spectral reference SEDs were constructed for a set of IR stellar standards (A
dwarfs, solar analogs, G9-M0 giants). A detailed error analysis was performed
to estimate proper uncertainties on the predicted flux values. It is shown that
the uncertainty on the predicted fluxes can be as high as 10%, but in case
high-resolution observational optical or near-IR data are available, and IR
excess can be excluded, the uncertainty on medium-resolution SEDs can be
reduced to 1-2% in the near-IR, to ~3% in the mid-IR, and to ~5% in the far-IR.
Moreover, it is argued that theoretical stellar atmosphere spectra are at the
moment the best representations for the IR fluxes of cool stellar standards.
When aiming at a determination of the spectrophotometric calibration of IR
spectrometers better than 3%, effort should be put into constructing an
appropriate set of stellar reference SEDs based on theoretical atmosphere
spectra for some 15 standard stars with spectral types between A0V and M0III.

708.4124 | Shell Effects in the First Sound Velocity of an Ultracold Fermi Gas | We investigate the first sound of a normal dilute and ultracold two-component
Fermi gas in a harmonic microtube, i.e. a cylinder with harmonic transverse
radial confinement in the length-scale of microns. We show that the velocity of
the sound that propagates along the axial direction strongly depends on the
dimensionality of the system. In particular, we predict that the first-sound
velocity display shell effects: by increasing the density, that is by inducing
the crossover from one-dimension to three-dimensions, the first-sound velocity
shows jumps in correspondence with the filling of harmonic modes. The

708.4125 | Comparing cosmic shear measures - Optimizing the Information content of
cosmic shear data vectors | We introduce an optimized data vector of cosmic shear measures (N). This data
vector has high information content, is not sensitive against B-mode
contamination and only shows small correlation between data points of different
angular scales. We show that a data vector of the two-point correlation
function (2PCF) in general contains more information on cosmological parameters
compared to a data vector of the aperture mass dispersion. Reason for this is
the fact that <M_ap^2> lacks the information of the convergence power spectrum
(P_\kappa) on large angular scales, which is contained in the 2PCF data vector.
Therefore we create a combined data vector N, which retains the advantages of
<M_ap^2> and in addition is also sensitive to the large-scale information of
P_\kappa. We compare the information content of the three data vectors by
performing a detailed likelihood analysis and use ray-tracing simulations to
derive the covariance matrices. In the last part of the paper we contaminate
all data vectors with B-modes on small angular scales and examine their
robustness against this contamination.The combined data vector strongly
improves constraints on cosmological parameters compared to <M_ap^2>. Although,
in case of a pure E-mode signal the information content of the 2PCF is higher,
in the more realistic case where B-modes are present the 2PCF data vector is
strongly contaminated and yields biased cosmological parameter estimates. N
shows to be robust against this contamination. Furthermore the individual data
points of N show a much smaller correlation compared to the 2PCF leading to an
almost diagonal covariance matrix.

708.4127 | The Dirichlet Casimir effect for $\phi^4$ theory in (3+1) dimensions: A
new renormalization approach | We calculate the next to the leading order Casimir effect for a real scalar
field, within $\phi^4$ theory, confined between two parallel plates in three
spatial dimensions with the Dirichlet boundary condition. In this paper we
introduce a systematic perturbation expansion in which the counterterms
automatically turn out to be consistent with the boundary conditions. This will
inevitably lead to nontrivial position dependence for physical quantities, as a
manifestation of the breaking of the translational invariance. This is in
contrast to the usual usage of the counterterms in problems with nontrivial
boundary conditions, which are either completely derived from the free cases or
at most supplemented with the addition of counterterms only at the boundaries.
Our results for the massive and massless cases are different from those
reported elsewhere. Secondly, and probably less importantly, we use a
supplementary renormalization procedure, which makes the usage of any analytic
continuation techniques unnecessary.

708.4132 | Exploring spatial nonlinearity using additive approximation | We propose to approximate the conditional expectation of a spatial random
variable given its nearest-neighbour observations by an additive function. The
setting is meaningful in practice and requires no unilateral ordering. It is
capable of catching nonlinear features in spatial data and exploring local
dependence structures. Our approach is different from both Markov field methods
and disjunctive kriging. The asymptotic properties of the additive estimators
have been established for $\alpha$-mixing spatial processes by extending the
theory of the backfitting procedure to the spatial case. This facilitates the
confidence intervals for the component functions, although the asymptotic
biases have to be estimated via (wild) bootstrap. Simulation results are
reported. Applications to real data illustrate that the improvement in

708.4133 | Some doubts on the validity of the foreground Galactic contribution
subtraction from microwave anisotropies | The Galactic foreground contamination in CMBR anisotropies, especially from
the dust component, is not easily separable from the cosmological or
extragalactic component. In this paper, some doubts will be raised concerning
the validity of the methods used to date to remove Galactic dust emission in
order to show that none of them achieves its goal.
First, I review the recent bibliography on the topic and discuss critically
the methods of foreground subtraction: the cross-correlation with templates,
analysis assuming the spectral shape of the Galactic components, the "maximum
entropy method", "internal linear combination", and "wavelet-based high
resolution fitting of internal templates". Second, I analyse the galactic
latitude dependence from WMAP data. The frequency dependence is discussed with
the data in the available literature. The result is that all methods of
subtracting the Galactic contamination are inaccurate. The galactic latitude
dependence analysis or the frequency dependence of the anisotropies in the
range 50-250 GHz put a constraint on the maximum Galactic contribution in the
power spectrum to be less than a ~10% (68% C. L.) for a ~1 degree scale, and
possibly higher for larger scales.
The origin of most of the signal in the CMBR anisotropies is not Galactic. In
any case, the subtraction of the Galaxy is not accurate enough to allow a
"precision Cosmology"; other sources of contamination (extragalactic, solar
system) are also present.

field spectroscopy with FLAMES/ARGUS | We study the two-dimensional distribution and kinematics of the stellar and
gaseous components in the centre of the blue compact dwarf galaxy, He 2-10. The
aim is to compare the kinematics of gas and stars in order to determine whether
they are consistent with one another, or if stars and gas can be decoupled due
to gravitational perturbations and feedback from star formation. We have used
the integral field unit ARGUS, part of FLAMES on the European Southern
Observatory's Very Large Telescope, to target the near-infrared Ca-triplet in
the central 300 times 480 parsecs of He 2-10. The selected wavelength regime
includes several prominent spectral features, including the Paschen series and
an [SIII] emission-line, which we have used to derive the kinematics of the
ionised interstellar medium. We find no systematic trend in the velocities of
the stars over the observed field of view and conclude that the stellar
kinematics is governed by random motions. This is in contrast to the motions
the ionised interstellar medium, where we find spatial velocity variations up
to 60 km/s. Our gas velocity field is consistent with previous studies of both
the molecular gas and the feedback-driven outflow in He 2-10. We interpret the
kinematic decoupling between the stars and the gas as He 2-10 being in the
process of transformation to a dwarf elliptical galaxy.

708.4135 | Strangeness content of the nucleon in quasielastic neutrino-nucleus
reactions | We present a systematic study of the sensitivity of quasielastic
neutrino-nucleus cross sections at intermediate energies to the strange quark
sea of the nucleon. To this end, we investigate the impact of the weak
strangeness form factors on the ratio of proton-to-neutron knockout, the ratio
of neutral-to-charged current cross sections, on the Paschos-Wolfenstein
relation, and on the longitudinal helicity asymmetry. The influence of axial as
well as vector strangeness effects is discussed. For the latter, we introduce
strangeness parameters from various hadron models and from a recent fit to data
from parity violating electron scattering.
In our model, the nuclear target is described in terms of a relativistic
mean-field approach. The effects of final-state interactions on the outgoing
nucleon are quantified within a relativistic multiple-scattering Glauber
approach. Our results are illustrated with cross sections for the scattering of
1 GeV neutrinos and antineutrinos off a $^{12}$C target.
Folding with a proposed FINeSSE (anti)neutrino energy-distribution has no
qualitative influence on the overall sensitivity of the cross-section ratios to
strangeness mechanisms. We show that vector strangeness effects are large and
strongly $Q^2$ dependent.

708.4136 | Solar cell Edge shunt isolation : A simplified approach | Edge shunts are among the main factors causing reduction in solar cell open
circuit voltage that is why their isolation is one of the main steps in solar
cell manufacturing. Many techniques have been employed to achieve this goal,
e.g. plasma etching, grinding, wet etching, etc. Unfortunately, these methods
have the disadvantages of being very expensive, single cell process and consume
a lot of dangerous chemicals. This work introduces a simple technique for edge
shunt isolation, by making a mechanical grove through the emitter and uses it
as back contact. It was found that with this technique the solar cell open
circuit voltage can be increased by an amount up to 200 mV. This technique is
simple, cheap and environmentally friendly in the sense that it uses no
chemicals.

708.4137 | A multiwavelength study of Galactic HII region Sh2-294 | We present the observational results of Galactic HII region S294, using
optical photometry, narrow-band imaging and radio continuum mapping at 1280

surface density profile indicates that the radius of the cluster associated
with the S294 region is ~ 2.3 arcmin. We found an anomalous reddening law for
the dust inside the cluster region and the ratio of total-to-selective
extinction is found to be 3.8+-0.1. We estimate the minimum reddening E (B-V) =
1.35 mag and distance of 4.8+-0.2 kpc to the region from optical CC and CM
diagrams. We identified the ionizing source of the HII region, and spectral
type estimates are consistent with a star of spectral type ~ B0 V. The 2MASS
JHKs images reveal a partially embedded cluster associated with the ionizing
source along with a small cluster towards the eastern border of S294. The
ionization front seen along the direction of small cluster in radio continuum
and Halpha images, might be due to the interaction of ionizing sources with the
nearby molecular cloud. We found an arc shaped diffuse molecular hydrogen
emission at 2.12 micron and a half ring of MSX dust emission which surrounds
the ionized gas in the direction of the ionization front. Self consistent
radiative transfer model of mid- to far-infrared continuum emission detected
near small cluster is in good agreement with the observed spectral energy
distribution of a B1.5 ZAMS star. The morphological correlation between the
ionised and molecular gas, along with probable time scale involved between the
ionising star, evolution of HII region and small cluster, indicates that the
star-formation activity observed at the border is probably triggered by the
expansion of HII region.

708.4139 | Non-linear Equation of State, COSMIC Acceleration and Deceleration
During Phantom-Dominance | Here, RS-II model of brane-gravity is considerd for phantom universe using
non-linear equation of stste. Phantom fluid is known to violate the weak energy
condition. In this paper, it is found that this characteristic of phantom
energy is affected drastically by the negative brane-tension $\lambda$ of the
RS-II model. It is interesting to see that upto a certain value of energy
density $\rho$ satisfying $\rho/\lambda < 1$, weak energy condition is violated
and universe super-accelerates. But as $\rho$ increases more, only strong
energy condition is violated and universe accelerates. When $1 < \rho/\lambda
<2$, even strong energy condition is not violated and universe decelerates.

earlier results of phantom universe exhibiting acceleration only.

708.4141 | Phases of 4D Scalar-tensor black holes coupled to Born-Infeld nonlinear
electrodynamics | Recent results show that when non-linear electrodynamics is considered the
no-scalar-hair theorems in the scalar-tensor theories (STT) of gravity, which
are valid for the cases of neutral black holes and charged black holes in the
Maxwell electrodynamics, can be circumvented. What is even more, in the present
work, we find new non-unique, numerical solutions describing charged black
holes coupled to non-linear electrodynamics in a special class of scalar-tensor
theories. One of the phases has a trivial scalar field and coincides with the
corresponding solution in General Relativity. The other four phases that we
find are characterized by the value of the scalar field charge. The causal
structure and some aspects of the stability of the solutions have also been
studied. For the scalar-tensor theories considered, the black holes have a
single, non-degenerate horizon, i.e., their causal structure resembles that of

708.4142 | Terahertz conductivity of localized photoinduced carriers in Mott
insulator YTiO$_{3}$ at low excitation density, contrasted with metallic
nature in band semiconductor Si | We performed optical-pump terahertz-probe measurements of a Mott insulator
YTiO$_{3}$ and a band semiconductor Si using a laser diode (1.47 eV) and a
femtosecond pulse laser (1.55 eV). Both samples possess long energy-relaxation
times (1.5 ms for YTiO$_{3}$ and 15 $\mu$s for Si); therefore, it is possible
to extract terahertz complex conductivities of photoinduced carriers under
equilibrium. We observed highly contrasting behavior - Drude conductivity in Si
and localized conductivity possibly obeying the Jonscher law in YTiO$_{3}$. The
carrier number at the highest carrier-concentration layer in YTiO$_{3}$ is
estimated to be 0.015 per Ti site. Anisotropic conductivity of YTiO$_{3}$ is
determined. Our study indicates that localized carriers might play an important
role in the incipient formation of photoinduced metallic phases in Mott
insulators. In addition, this study shows that the transfer-matrix method is
effective for extracting an optical constant of a sample with a spatially
inhomogeneous carrier distribution.

708.4143 | Stephani-Schutz quantum cosmology | We study the Stephani quantum cosmological model in the presence of a
cosmological constant in radiation dominated Universe. In the present work the
Schutz's variational formalism which recovers the notion of time is applied.
This gives rise to Wheeler-DeWitt equations which can be cast in the form of
Schr\"odinger equations for the scale factor. We find their eigenvalues and
eigenfunctions by using the Spectral Method. Then we use the eigenfunctions in
order to construct wave packets and evaluate the time-dependent expectation
value of the scale factor, which is found to oscillate between non-zero finite
maximum and minimum values. Since the expectation value of the scale factor

708.4146 | Z_3 Polyakov Loop Models and Inverse Monte-Carlo Methods | We study effective Polyakov loop models for SU(3) Yang-Mills theory at finite
temperature. A comprehensive mean field analysis of the phase diagram is
carried out and compared to the results obtained from Monte-Carlo simulations.
We find a rich phase structure including ferromagnetic and antiferromagnetic
phases. Due to the presence of a tricritical point the mean field approximation
agrees very well with the numerical data. Critical exponents associated with
second-order transitions coincide with those of the Z_3 Potts model. Finally,

708.4148 | Electron and lattice structure of ultra thin Ag films on Si(111) and
Si(001) | We studied the low temperature (T<130K) growth of Ag on Si(001) and Si(111)
flat surfaces prepared by Si homo epitaxy with the aim to achieve thin metallic
films. The band structure and morphology of the Ag overlayers have been
investigated by means of XPS, UPS, LEED, STM and STS. Surprisingly a
(root3xroot3)R30^o LEED structure for Ag films has been observed after
deposition of 2-6 ML Ag onto a Si(111)(root3xroot3)R30^o Ag surface at low
temperatures. XPS investigations showed that these films are solid, and UPS
measurements indicate that they are metallic. However, after closer STM studies
we found that these films consists of sharp Ag islands and (root3xroot3)R30^o
Ag flat terraces in between. On Si(001) the low-temperature deposition yields
an epitaxial growth of Ag on clean Si(001)2x1 with a twinned Ag(111) structure
at coverages as low as 10 ML. Furthermore the conductivity of few monolayer Ag
films on Si(100) surfaces has been studied as a function of temperature (40-300
K).
| cond-mat.mtrl-sci cond-mat.stat-mech | we studied the low temperature t130k growth of ag on si001 and si111 flat surfaces prepared by si homo epitaxy with the aim to achieve thin metallic films the band structure and morphology of the ag overlayers have been investigated by means of xps ups leed stm and sts surprisingly a root3xroot3r30o leed structure for ag films has been observed after deposition of 26 ml ag onto a si111root3xroot3r30o ag surface at low temperatures xps investigations showed that these films are solid and ups measurements indicate that they are metallic however after closer stm studies we found that these films consists of sharp ag islands and root3xroot3r30o ag flat terraces in between on si001 the lowtemperature deposition yields an epitaxial growth of ag on clean si0012x1 with a twinned ag111 structure at coverages as low as 10 ml furthermore the conductivity of few monolayer ag films on si100 surfaces has been studied as a function of temperature 40300 k | [['we', 'studied', 'the', 'low', 'temperature', 't130k', 'growth', 'of', 'ag', 'on', 'si001', 'and', 'si111', 'flat', 'surfaces', 'prepared', 'by', 'si', 'homo', 'epitaxy', 'with', 'the', 'aim', 'to', 'achieve', 'thin', 'metallic', 'films', 'the', 'band', 'structure', 'and', 'morphology', 'of', 'the', 'ag', 'overlayers', 'have', 'been', 'investigated', 'by', 'means', 'of', 'xps', 'ups', 'leed', 'stm', 'and', 'sts', 'surprisingly', 'a', 'root3xroot3r30o', 'leed', 'structure', 'for', 'ag', 'films', 'has', 'been', 'observed', 'after', 'deposition', 'of', '26', 'ml', 'ag', 'onto', 'a', 'si111root3xroot3r30o', 'ag', 'surface', 'at', 'low', 'temperatures', 'xps', 'investigations', 'showed', 'that', 'these', 'films', 'are', 'solid', 'and', 'ups', 'measurements', 'indicate', 'that', 'they', 'are', 'metallic', 'however', 'after', 'closer', 'stm', 'studies', 'we', 'found', 'that', 'these', 'films', 'consists', 'of', 'sharp', 'ag', 'islands', 'and', 'root3xroot3r30o', 'ag', 'flat', 'terraces', 'in', 'between', 'on', 'si001', 'the', 'lowtemperature', 'deposition', 'yields', 'an', 'epitaxial', 'growth', 'of', 'ag', 'on', 'clean', 'si0012x1', 'with', 'a', 'twinned', 'ag111', 'structure', 'at', 'coverages', 'as', 'low', 'as', '10', 'ml', 'furthermore', 'the', 'conductivity', 'of', 'few', 'monolayer', 'ag', 'films', 'on', 'si100', 'surfaces', 'has', 'been', 'studied', 'as', 'a', 'function', 'of', 'temperature', '40300', 'k']] | [-0.06780888373726948, 0.16236022830754895, -0.1019489856496934, -0.05072326682087395, 0.06337757830868565, -0.18107781730622294, 0.09024302822748019, 0.5362725597896403, -0.24242511285889534, -0.3053314703051001, 0.028053167377478413, -0.33576822381827137, -0.10335474417454774, 0.23154434034630897, -0.0029600133879050133, 0.04827050286947915, 0.0015709054506113452, -0.15451040844350392, -0.16551781802197857, -0.2780517869737871, 0.2520353836488099, 0.10300978550747518, 0.3572099625741342, 0.11939508464307555, -0.0027298956763960663, -0.012339716050173005, 0.15741324821137823, 0.055390265788282114, -0.2402995550561407, 0.06104591565167685, 0.26863046204671265, -0.13969280076693863, 0.1585227717134741, -0.5266023390115269, -0.24433643330008753, -0.12190612571374063, 0.09347783333712047, 0.05724934354765273, -0.15740854490488287, -0.19192882321114021, 0.13228035947428116, -0.03900682891929342, -0.04340209307209138, -0.041536141499396294, -0.022656472329981626, -0.013810562931241529, -0.14581048616899117, 0.055737339050298734, 0.060855000315895004, 0.1832050256491188, -0.08037689908017073, -0.16556585589724201, -0.2322004412451098, 0.008299394928279424, 0.013047011765546256, -0.004323011617957344, 0.22340656926314678, -0.01980521281159693, -0.04697657073998163, 0.2968619173152312, -0.06149811230960392, -0.005996881635679353, 0.25855305124554906, -0.22995563874682112, -0.05956647535485606, 0.21371303091366445, 0.08774051848017882, 0.17314631915125514, -0.12461979778280723, 0.13594475129277506, -0.01016897241915426, 0.23866079133604803, 0.20978477954744332, 0.006851477659637889, 0.21200738326541238, 0.24740017202172068, 6.4610999317899824e-06, 0.10277642187542252, -0.16546640706158453, 0.09909104795285291, -0.11295493062465421, -0.22921736838987036, -0.23039158611528335, 0.1086489051850813, -0.06276241950568698, -0.21310127243820218, 0.33357940545726206, -0.019926636557905903, 0.2300877200649871, -0.07421648650610399, 0.17938402487385657, 0.013272100260421154, 0.05888449009357681, -0.024966710402570185, 0.21200285886804904, 0.18425026784590895, 0.10922402473206017, -0.2319929280919173, 0.16377797978779962, -0.015768301691259107] |
