709.4535 | Prospects of a Search for a New Massless Neutral Gauge Boson at the ILC | Prospects to search for a new massless neutral gauge boson, the paraphoton,
in e+ e- collisions at center-of-mass energies of 0.5 and 1 TeV are studied.
The paraphoton naturally appears in models with abelian kinetic mixing. A
possible realistic model independent lowest order effective Lagrangian contains
magnetic interactions of the paraphoton with the Standard Model fermion fields.
These interactions are proportional to the fermion mass and grow with energy,
with however very weak paraphoton couplings to ordinary matter. At the ILC, a
potentially interesting process to search for the paraphoton is its radiation
off top quarks, so that the event topology to be searched for is a pair of
acoplanar top quark jets with missing energy. By combining many discriminating
features of signal and background events efficient paraphoton event selection
was achieved allowing to set limits for the top-paraphoton coupling. Arguments
in favor of the missing energy as the paraphoton with spin 1 are discussed.

709.4536 | Approximately Independent Features of Languages | To facilitate the testing of models for the evolution of languages, the
present note offers a set of linguistic features that are approximately
independent of each other. To find these features, the adjusted Rand index R'
is used to estimate the degree of pairwise relationship among 130 linguistic
features in a large published database. Many of the R' values prove to be near
0, as predicted for independent features, and a subset of 47 features is found
with an average R' of -0.0001. These 47 features are recommended for use in
statistical tests that require independent units of analysis.

relations (i) $p=k\rho$, (ii) $p=k\rho-\frac{B(v)}{\rho^{\alpha}}$ (variable

the nature of singularity in gravitational collapse for the above equations of

namely, (i) $k=0$, $B=$ constant (generalized Chaplygin), (ii) $B=$ constant
(modified Chaplygin). It is found that the nature of singularity is independent
of these choices of different equation of state except for variable Chaplygin
model. Choices of various parameters are shown in tabular form. Finally,

709.4539 | Distributed Quantum Computation Based-on Small Quantum Registers | We describe and analyze an efficient register-based hybrid quantum
computation scheme. Our scheme is based on probabilistic, heralded optical
connection among local five-qubit quantum registers. We assume high fidelity
local unitary operations within each register, but the error probability for
initialization, measurement, and entanglement generation can be very high
(~5%). We demonstrate that with a reasonable time overhead our scheme can
achieve deterministic non-local coupling gates between arbitrary two registers
with very high fidelity, limited only by the imperfections from the local
unitary operation. We estimate the clock cycle and the effective error
probability for implementation of quantum registers with ion-traps or
nitrogen-vacancy (NV) centers. Our new scheme capitalizes on a new efficient
two-level pumping scheme that in principle can create Bell pairs with
arbitrarily high fidelity. We introduce a Markov chain model to study the
stochastic process of entanglement pumping and map it to a deterministic
process. Finally we discuss requirements for achieving fault-tolerant operation
with our register-based hybrid scheme, and also present an alternative approach
to fault-tolerant preparation of GHZ states.

709.4541 | Quasi-Spherical Gravitational Collapse in higher dimension and the
effect of equation of state | Gravitational collapse in (n+2) dimensional quasi-spherical space-time is
studied for a fluid with non vanishing radial pressure. An exact analytic
solution is obtained (ignoring the arbitrary integration function) for the
equation of state $p_{r}=(\gamma-1)\rho.$ The singularity is studied locally by
comparing the time of formation of apparent horizon and the central shell
focusing singularity while the global nature of the final fate of collapse is
characterized by the existence of radial null geodesic. It is revealed that the
end state of collapse for D dimension with equation of state $p=-\rho$, for
(D$-$1) dimensional dust and (D$-$2)dimension with equation of state $p=\rho$
are identical.

709.4542 | Real-time observation of polyelectrolyte-induced binding of charged
bilayers | We present real-time observations by confocal microscopy of the dynamic
behavior of multilamellar vesicles (MLVs), composed of charged synthetic
lipids, when put in contact with oppositely charged polyelectrolyte (PE)
molecules. We find that the MLVs exhibit astonishing morphological transitions,
which result from the discrete and progressive binding of the charged bilayers
induced by a high PE concentration gradient. Our physical picture is confirmed
by quantitative measurements of the fluorescence intensity as the bilayers bind
to each other. The shape transitions lead eventually to the spontaneous
formation of hollow capsules, whose thick walls are composed of lipid

709.4545 | Post common envelope binaries from SDSS. II: Identification of 9 close
binaries with VLT/FORS2 | The Sloan Digital Sky Survey turned out to be very efficient in identifying
white dwarf/main sequence binaries (WDMS). The population of WDMS systems
consists of wide systems whose stellar components evolve like single stars and
- more interesting in the context of close binary evolution - PCEBs. We pursue
a large-scale follow-up survey to identify and characterise the PCEBs among the
WDMS binaries that have been found with SDSS. We use a two-step strategy with
the identification of PCEBs among WDMS in the first and orbital period
determinations in the second phase. Here we present first results of our
VLT/FORS2 pilot-study that has the target of identifying the PCEBs among the
fainter (g>~18.5) SDSS-WDMS. From published SDSS catalogues we selected 26 WDMS
targets to be observed with VLT/FORS2. Using a spectral decomposition/fitting
technique we determined the white dwarf effective temperatures and surface
gravities, masses, and secondary star spectral types for all WDMS in our
sample. We used the NaI 8183.27,8194.81 doublet to measure radial velocity
variations of our targets and performed additional follow-up spectroscopy using
Magellan-Clay/LDSS3 of two systems showing significant radial velocity
variations. Among the 26 WDMS systems we find 9 strong PCEB candidates showing
clear (>=3sigma) radial velocity variations and we estimate the fraction of
PCEBs among SDSS WDMS to be ~35%. We find indications for a dependence of the
relative number of PCEBs among SDSS-WDMS on the spectral type of the secondary
star. These results are subject to small number statistics and need to be
confirmed by additional observations. For two of the identified PCEB
candidates, SDSSJ1047+0523 and SDSSJ1414-0132, we measured the orbital periods
to be 9.17hrs and 17.48hrs respectively.

binaries that have been found with sdss we use a twostep strategy with the identification of pcebs among wdms in the first and orbital period determinations in the second phase here we present first results of our vltfors2 pilotstudy that has the target of identifying the pcebs among the fainter g185 sdsswdms from published sdss catalogues we selected 26 wdms targets to be observed with vltfors2 using a spectral decompositionfitting technique we determined the white dwarf effective temperatures and surface gravities masses and secondary star spectral types for all wdms in our sample we used the nai 818327819481 doublet to measure radial velocity variations of our targets and performed additional followup spectroscopy using magellanclayldss3 of two systems showing significant radial velocity variations among the 26 wdms systems we find 9 strong pceb candidates showing clear 3sigma radial velocity variations and we estimate the fraction of pcebs among sdss wdms to be 35 we find indications for a dependence of the relative number of pcebs among sdsswdms on the spectral type of the secondary star these results are subject to small number statistics and need to be confirmed by additional observations for two of the identified pceb candidates sdssj10470523 and sdssj14140132 we measured the orbital periods to be 917hrs and 1748hrs respectively | [['the', 'sloan', 'digital',

709.4548 | Three episodes of jet activity in the FRII radio galaxy B0925+420 | We present Very Large Array images of a "Double-Double Radio Galaxy", a class
of objects in which two pairs of lobes are aligned either side of the nucleus.
In this object, B0925+420, we discover a third pair of lobes, close to the core
and again in alignment with the other lobes. This first-known "Triple-Double"
object strongly increases the likelihood that these lobes represent mutiple
episodes of jet activity, as opposed to knots in an underlying jet. We model
the lobes in terms of their dynamical evolution. We find that the inner pair of
lobes is consistent with the outer pair having been displaced buoyantly by the
ambient medium. The middle pair of lobes is more problematic - to the extent
where an alternative model interpreting the middle and inner "lobes" as
additional bow shocks within the outer lobes may be more appropriate - and we
discuss the implications of this on our understanding of the density of the
ambient medium.

709.455 | Strong coupling analysis of QED$_3$ for excitation spectrum broadening
in undoped high-temperature superconductor | Theory of quantum electrodynamics in three spatial-time dimension is applied
to the two-dimensional $S=1/2$ quantum Heisenberg antiferromagnet in order to
investigate a doped hole in high-temperature superconductors. Strong coupling
analysis of the U(1) gauge field interaction is carried out to describe
spectral broadening observed in the undoped compounds. It is found that the
fermionic quasiparticle spectrum is of Gaussian form with the width about 3J,
with J being the superexchange interaction energy. The energy shift of the
spectrum is on the order of the quasiparticle band width, which suggests that

709.4551 | A Near-Infrared Stellar Spectral Library: III. J-Band Spectra | This paper is the third in the series of papers published on near-infrared
(NIR) stellar spectral library by Ranade et al. (2004 & 2007). The observations
were carried out with 1.2 meter Gurushikhar Infrared Telescope (GIRT), at Mt.
Abu, India using a NICMOS3 HgCdTe $256 \times 256$ NIR array based
spectrometer. In paper I (Ranade et al. 2004), H-band spectra of 135 stars at a
resolution of $\sim 16$\AA & paper II (Ranade et al. 2007), K band spectra of
114 stars at a resolution of $\sim 22$\AA were presented. The J-band library
being released now consists of 126 stars covering spectral types O5--M8 and
luminosity classes I--V. The spectra have a moderate resolution of $\sim
12.5$\AA in the J band and have been continuum shape corrected to their
respective effective temperatures. The complete set of library in near-infrared
(NIR) will serve as a good database for researchers working in the field of
stellar population synthesis. The complete library in J, H & K is available
online at: http://vo.iucaa.ernet.in/$\sim$voi/NIR\_Header.html

709.4552 | Distributed N-body Simulation on the Grid Using Dedicated Hardware | We present performance measurements of direct gravitational N -body
simulation on the grid, with and without specialized (GRAPE-6) hardware. Our
inter-continental virtual organization consists of three sites, one in Tokyo,
one in Philadelphia and one in Amsterdam. We run simulations with up to 196608
particles for a variety of topologies. In many cases, high performance
simulations over the entire planet are dominated by network bandwidth rather
than latency. With this global grid of GRAPEs our calculation time remains
dominated by communication over the entire range of N, which was limited due to
the use of three sites. Increasing the number of particles will result in a
more efficient execution. Based on these timings we construct and calibrate a
model to predict the performance of our simulation on any grid infrastructure
with or without GRAPE. We apply this model to predict the simulation
performance on the Netherlands DAS-3 wide area computer. Equipping the DAS-3
with GRAPE-6Af hardware would achieve break-even between calculation and
communication at a few million particles, resulting in a compute time of just
over ten hours for 1 N -body time unit. Key words: high-performance computing,

description of the experimentally measured dependence of the generated power on
the bias current in a moderate super-critical range of bias current variation.

ultracold $^6$Li and $^{87}$Rb atoms in their respective hyperfine ground

for the $^6$Li cloud induced by inelastic Li-Rb-Rb three-body collisions. The
magnetic field values where they occur represent important benchmarks for an
accurate determination of the interspecies interaction potentials. A broad
Feshbach resonance located at 1066.92 G opens interesting prospects for the
creation of ultracold heteronuclear molecules. We furthermore observe a strong
enhancement of the narrow p-wave Feshbach resonance in collisions of $^6$Li
atoms at 158.55 G in the presence of a dense $^{87}$Rb cloud. The effect of the
$^{87}$Rb cloud is to introduce Li-Li-Rb three-body collisions occurring at a
higher rate than Li-Li-Li collisions.

709.4556 | Charge-to-spin conversion of electron entanglement states and
spin-interaction-free solid-state quantum computation | Without resorting to spin-spin coupling, we propose a scalable spin quantum
computing scheme assisted with a semiconductor multiple-quantum-dot structure.
The techniques of single electron transitions and the nanostructure of
quantum-dot cellular automata (QCA) are used to generate charge entangled
states of two electrons, which are then converted into spin entanglement states
using single-spin rotations only. Deterministic two-qubit quantum gates are
also manipulated using only single-spin rotations with the help of QCA. A
single-shot readout of spin states can be carried out by coupling the multiple
dot structure to a quantum point contact. As a result, deterministic
spin-interaction-free quantum computing can be implemented in semiconductor
nanostructure.

709.4558 | Practical Multiwriter Lock-Free Queues for "Hard Real-Time" Systems
without CAS | FIFO queues with a single reader and writer can be insufficient for "hard
real-time" systems where interrupt handlers require wait-free guarantees when
writing to message queues. We present an algorithm which elegantly and
practically solves this problem on small processors that are often found in
embedded systems. The algorithm does not require special CPU instructions (such
as atomic CAS), and therefore is more robust than many existing methods that
suffer the ABA problem associated with swing pointers. The algorithm gives
"first-in, almost first-out" guarantees under pathological interrupt

709.456 | The distant galaxy cluster CL0016+16: X-ray analysis up to $R_{200}$ | To study the mass distribution of galaxy clusters up to their Virial radius,
CL0016+16 seems to be a good candidate,since it is a bright massive cluster,
previously considered as being dynamically relaxed. Using XMM-Newton
observations of CL0016+16, we performed a careful X-ray background analysis,
and we detected convincingly its X-ray emission up to $R_{200}$. We then
studied its dynamical state with a detailed 2D temperature and surface
brightness analysis of the inner part of the cluster. Using the assumption of
both spherical symmetry and hydrostatic equilibrium (HE) we can determine the
main cluster parameters: total mass, temperature profile, surface brightness
profile and $\beta$-parameter. We also build a temperature map which clearly
exhibits departure from spherical symmetry in the centre. To estimate the
influence of these perturbations onto our total mass estimate, we also compute
the total mass in the framework of the HE approach, but this time with various
temperature profiles obtained in different directions. These various total mass
estimates are consistent with each other. The temperature perturbations are
clear signatures of ongoing merger activity. We also find significant residuals
after subtracting the emissivity map by a 2D $\beta$-model fit. We conclude
that, although CL0016+16 shows clear signs of merger activity and departure
from spherical symmetry in the centre, its X-ray emissivity can be detected up
to $R_{200}$ and the corresponding mass $M_{200}$ can be computed directly. It
is therefore a good candidate to study cosmological scaling laws as predicted
by the theory.

709.4561 | Semi-Classical Dynamics in Quantum Spin Systems | We consider two limiting regimes, the large-spin and the mean-field limit,
for the dynamical evolution of quantum spin systems. We prove that, in these
limits, the time evolution of a class of quantum spin systems is determined by
a corresponding Hamiltonian dynamics of classical spins. This result can be
viewed as a Egorov-type theorem. We extend our results to the thermodynamic
limit of lattice spin systems and continuum domains of infinite size, and we
study the time evolution of coherent spin states in these limiting regimes.

709.4562 | A hydrodynamic scheme for two-component winds from hot stars | We have developed a time-dependent two-component hydrodynamics code to
simulate radiatively-driven stellar winds from hot stars. We use a
time-explicit van Leer scheme to solve the hydrodynamic equations of a
two-component stellar wind. Dynamical friction due to Coulomb collisions
between the passive bulk plasma and the line-scattering ions is treated by a
time-implicit, semi-analytic method using a polynomial fit to the Chandrasekhar
function. This gives stable results despite the stiffness of the problem. This
method was applied to model stars with winds that are both poorly and
well-coupled. While for the former case we reproduce the mCAK solution, for the
latter case our solution leads to wind decoupling.

709.4563 | Systematic generation of entanglement measures for pure states | We propose a method to generate entanglement measures systematically by using
the irreducible decomposition of some copies of a state under the local unitary
(LU) transformations. It is applicable to general multipartite systems. We show
that there are entanglement monotones corresponding to singlet representations
of the LU group. They can be evaluated efficiently in an algebraic way, and
experimentally measurable by local projective measurements of the copies of the
state. Non-singlet representations are also shown to be useful to classify

709.4565 | Topological Dynamics of 2D Cellular Automata | Topological dynamics of cellular automata (CA), inherited from classical
dynamical systems theory, has been essentially studied in dimension 1. This
paper focuses on 2D CA and aims at showing that the situation is different and
more complex. The main results are the existence of non sensitive CA without
equicontinuous points, the non-recursivity of sensitivity constants and the
existence of CA having only non-recursive equicontinuous points. They all show
a difference between the 1D and the 2D case. Thanks to these new constructions,
we also extend undecidability results concerning topological classification
previously obtained in the 1D case.

709.4567 | Structural and Nucleosynthetic Evolution of Metal-poor and Metal-free
Low and Intermediate Mass Stars | We report on an investigation into stellar evolution and nucleosynthesis in
the low and extremely low metallicity regime, including models of stars with a
pure Big Bang composition (i.e. Z=0). The metallicity range of the extremely
metal poor (EMP) models we have calculated is -6.5 < [Fe/H] < -3.0, whilst our
models are in the mass range 0.85 < M < 3.0 Msun. Many of the EMP and Z=0
models experience violent evolutionary episodes not seen at higher
metallicities. We refer to these events as `Dual Flashes' since they are
characterised by peaks in the hydrogen and helium burning luminosities
occurring at roughly the same time. Some of the material processed by these
events is later dredged up by the convective envelope, causing signifcant
surface pollution. These events have been reported by previous studies, so our
results reaffirm their occurrence -- at least in 1D stellar models. The novelty
of this study is that we have calculated the entire evolution of the Z=0 and
EMP models, from the ZAMS to the end of the TPAGB, including detailed
nucleosynthesis. We have also calculated the nucleosynthetic yields, which will
soon be available in electronic format. Although subject to many uncertainties
these are, as far as we are aware, the only yields available in this mass and
metallicity range. In this paper we briefy describe some of the results in the
context of abundance observations of EMP halo stars. This work formed part of
SWC's PhD thesis (completed in March 2007) and a series of subsequent papers
will describe the results of the study in more detail.

709.4568 | Gamma-Ray Burst high energy emission from Internal Shocks | In this paper we study synchrotron and synchrotron self Compton (SSC)
emission from internal shocks (IS) during the prompt and X-ray flare phases of
Gamma-Ray Bursts (GRBs). The aim is to test the IS model for the flare emission
and for whether GRBs can be GeV sources. We determine the parameters for which
the IS model can account for the observed prompt and X-ray flares emission, and
study the detectability of the high energy SSC emission by the AGILE and GLAST
satellites. We find that the detectability of the SSC emission during the
prompt phase of GRBs improves for higher values of the fireball Lorentz factor
and of the temporal variability. If IS is the mechanism responsible of the
flare emission, and the Lorentz factor of the shells producing the flare is of
the order of 100, the flare light curves are expected to present some
substructures with temporal variability of 10-100 ms which are much smaller
than the average duration of flares, and similar to those observed during the
prompt phase of GRBs. If one assumes lower Lorentz factors, such as 10-25, then
a larger temporal variaibility of 40 s can also account for the observed flare
properties. However in this case we predict that X-ray flares do not have a
counterpart at very high energies (MeV-GeV). An investigation on the
substructures of the X-ray flares light curves, and simultaneous X-ray and high
energy observations, will allow us to corroborate the hypothesis that late IS
are responsible of the X-ray flares.

709.457 | Gamma-Ray Emission from PWNe Interacting with Molecular Clouds | We consider a situation in which a pulsar (and its nebula) is formed inside
or close to a high density regions of a molecular cloud. We apply a recent
model for the gamma radiation of pulsar wind nebulae (PWN), which includes not
only radiation processes due to injected leptons but also processes due to
injection of relativistic hadrons, in order to calculate the expected gamma-ray
emission from such interacting PWNe. The example calculations have been
performed for two objects of this type from which directions TeV gamma-ray
sources have recently been observed (IC443 and W41). We show that the gamma-ray
emission below a few TeV can be produced by leptons accelerated in the past in
the vicinity of the pulsars. gamma-rays with energies above ~10 TeV can be
produced by hadrons interacting with the matter inside the supernova remnant
and surrounding dense clouds. In contrary to the low energy TeV emission, this
high energy TeV emission should be correlated with the location of dense clouds
able to capture hadrons due to their strong magnetic fields.

709.4571 | Einstein's Lost Battles and Neglected Achievements | We analyze some of Einstein's failures to accomplish tasks which he posed to
himself, notably deterministic interpretation of Quantum mechanics and
formulation of the Unified theory of physical interactions, putting them into
broader ontological and epistemological context. We highlight, on the other
hand, a number of his contributions that have been unjustly neglected by the
physical community, like the semiclassical quantization principle and the

709.4572 | Measurement of Heavy Quark cross-sections at CDF | The measurement of heavy quark cross-sections provides important tests of the
QCD theory. This paper reviews recent measurements of single b-quark and
correlated b-quark cross-sections at CDF. Two new measurements of the single
b-quark production at CDF agree with the first result from CDF Run II. This
clarifies the experimental situation and confirms the recent agreement of
theoretical prediction with data. A new measurement of the correlated
$b\bar{b}$ cross-section with dimuon events at CDF is presented. It agrees with
theory and it does not confirm the anomalously large $b\bar{b}$ cross-section
seen in Run I by CDF and D${\not {\rm O}}$ in dimuon events.

709.4573 | Pulsating B and Be stars in the Small Magellanic Cloud | Context: Stellar pulsations in main-sequence B-type stars are driven by the
kappa-mechanism due to the Fe-group opacity bump. The current models do not
predict the presence of instability strips in the B spectral domain at very low
metallicities. As the metallicity of the SMC is lower than Z=0.005, it
constitutes a very suitable object to test these predictions.
Aims: The main objective is to investigate the existence of B-type pulsators
at low metallicities, searching for short-term periodic variability in
absorption-line B and Be stars in the SMC. The analysis has been performed in a
sample of 313 B and Be stars with fundamental astrophysical parameters
accurately determined from high-resolution spectroscopy.
Methods: Photometric light curves of the MACHO project have been analyzed
using standard Fourier techniques and linear and non-linear least squares
fitting methods. The position of the pulsating stars in the HR diagram has been
used to ascertain their nature and to map the instability regions in the SMC.
Results: We have detected 9 absorption-line B stars showing short-period
variability, two among them being multiperiodic. One star is most likely a beta
Cephei variable and the remaining 8 are SPB stars. The SPB instability strip in
the SMC is shifted towards higher temperatures than the Galaxy. In the Be star
sample, 32 stars are short-period variables, 20 among them multiperiodic. 4.9%
of B stars and 25.3% of Be stars are pulsating stars.
Conclusions: beta Cephei and SPB stars do exist at the SMC metallicity. The
fractions of SPB stars and pulsating Be stars in the SMC are lower than in the
Galaxy. The fraction of pulsating Be stars in the SMC is much higher than the
fraction of pulsating absorption-line B stars, as in the Galaxy.

709.4574 | Light quark masses and pseudoscalar decay constants from Nf=2 Lattice
QCD with twisted mass fermions | We present the results of a lattice QCD calculation of the average up-down
and strange quark masses and of the light meson pseudoscalar decay constants
with Nf=2 dynamical fermions. The simulation is carried out at a single value
of the lattice spacing with the twisted mass fermionic action at maximal twist,
which guarantees automatic O(a)-improvement of the physical quantities. Quark
masses are renormalized by implementing the non-perturbative RI-MOM
renormalization procedure. Our results for the light quark masses are
m_ud^{msbar}(2 GeV)= 3.85 +- 0.12 +- 0.40 MeV, m_s^{msbar}(2 GeV) = 105 +- 3 +-
9 MeV and m_s/m_ud = 27.3 +- 0.3 +- 1.2. We also obtain fK = 161.7 +- 1.2 +-
3.1 MeV and the ratio fK/fpi=1.227 +- 0.009 +- 0.024. From this ratio, by using
the experimental determination of Gamma(K-> mu nu (gamma))/Gamma(pi -> mu nu
(gamma)) and the average value of |Vud| from nuclear beta decays, we obtain
|Vus|=0.2192(5)(45), in agreement with the determination from Kl3 decays and
the unitarity constraint.

709.4575 | Density profiles in the raise and peel model with and without a wall.
Physics and combinatorics | We consider the raise and peel model of a one-dimensional fluctuating
interface in the presence of an attractive wall. The model can also describe a
pair annihilation process in a disordered unquenched media with a source at one
end of the system. For the stationary states, several density profiles are
studied using Monte Carlo simulations. We point out a deep connection between
some profiles seen in the presence of the wall and in its absence. Our results
are discussed in the context of conformal invariance ($c = 0$ theory). We
discover some unexpected values for the critical exponents, which were obtained
using combinatorial methods.
We have solved known (Pascal's hexagon) and new (split-hexagon) bilinear
recurrence relations. The solutions of these equations are interesting on their
own since they give information on certain classes of alternating sign
matrices.

709.4576 | Confinement of Cosmic Rays in Dark Matter clumps | Some part of the relic Dark Matter is distributed in small-scale clumps which
survived structure formation in inflation cosmological scenario. The
annihilation of DM inside these clumps is a strong source of stable charged
particles which can have a substantial density near the clump core. The
streaming of the annihilation products from the clump can enhance

709.4577 | Sub-Kelvin Cooling of a Macroscopic Oscillator and femto-Newton Force
Measurement | Measuring very small forces, particularly those of a gravitational nature,
has always been of great interest, as fundamental tests of our understanding of
the physical laws. Ultra-long period mechanical oscillators, typically used in
such measurements, will have kT/2 of thermal energy associated with each degree
of freedom, owing to the equal-partition of energy. Moreover, additional
seismic fluctuations in the low frequency band can raise this equivalent
temperature significantly to 10^5 K. Recently, various methods using
opto-mechanical forces have been reported to decrease this thermal energy for
MHz, micro-cantilever oscillators, effectively cooling them. Here we show the
direct, dynamical cooling of a gram-size, macroscopic oscillator to 300 mK in
equivalent temperature - noise reduction by a factor of 10^6. By precisely
measuring the torsional oscillator's position, we dynamically provide an
external 'viscous' damping force. Such an added, dissipative force is
essentially free of noise, resulting in rapid cooling of the oscillator.
Additionally, we observe the time-dependent cooling process, at various cooling
force parameters. This parameter dependence agrees well with a simple physical
model which we provide. We further show that the device is sensitive to forces
as small as <100 fN - a force only a few percent of that typically exerted by a
single biological molecule or that observed in a typical gravity experiment. We
also demonstrate the dynamic control of the oscillator's natural frequency,
over a span of nearly two decades. The method may find important applications
in precision measurements of very weak forces.

709.4578 | On the Nature of Precursors in the Radio Pulsar Profiles | In the average profiles of several radio pulsars, the main pulse is
accompanied by the preceding component. This so called precursor is known for
its distinctive polarization, spectral, and fluctuation properties. Recent
single-pulse observations hint that the sporadic activity at the extreme
leading edge of the pulse may be prevalent in pulsars. We for the first time
propose a physical mechanism of this phenomenon. It is based on the induced
scattering of the main pulse radiation into the background. We show that the
scattered component is directed approximately along the ambient magnetic field
and, because of rotational aberration in the scattering region, appears in the
pulse profile as a precursor to the main pulse. Our model naturally explains
high linear polarization of the precursor emission, its spectral and
fluctuation peculiarities as well as suggests a specific connection between the
precursor and the main pulse at widely spaced frequencies. This is believed to

709.4581 | Detecting a Lorentz-Violating Field in Cosmology | We consider cosmology in the Einstein-aether theory (the generally covariant
theory of gravitation coupled to a dynamical timelike Lorentz-violating vector
field) with a linear aether-Lagrangian. The 3+1 spacetime splitting approach is
used to derive covariant and gauge invariant perturbation equations which are
valid for a general class of Lagrangians. Restricting attention to the
parameter space of these theories which is consistent with local gravity
experiments, we show that there are tracking behaviors for the aether field,
both in the background cosmology and at linear perturbation level. The
primordial power-spectrum of scalar perturbations in this model is shown to be
the same that predicted by standard general relativity. However, the
power-spectrum of tensor perturbation is different from that in general
relativity, but has a smaller amplitude and so cannot be detected at present.
We also study the implications for late-time cosmology and find that the
evolution of photon and neutrino anisotropic stresses can source the aether
field perturbation during the radiation and matter dominated epochs, and as a
result the CMB and matter power spectra are modified. However these effects are
degenerate with respect to other cosmological parameters, such as neutrino
masses and the bias parameter in the observed galaxy spectrum.

709.4582 | Dynamical Chirally Improved Quarks: First Results for Hadron Masses | We present first results for a study with two mass-degenerate dynamical
Chirally Improved (CI) fermions on lattices of spatial extent 2.4 fm. The CI
Dirac operator obeys the Ginsparg-Wilson condition in good approximation. The
pion mass we use is still large O(470 MeV) for the 16**3*32 lattices with
lattice spacing of 0.15 fm. The hadron masses are obtained with the variational
technique and the results compared with earlier quenched calculations with
similar lattice parameters. We find indications for the isovector, scalar meson
a0(980) near the experimental value, in contradistinction to quenched results
which always produced a mass value compatible with the first excitation
a0(1450).

709.4583 | Chiral effective-field theory in the Delta(1232) region: II. radiative
pion photoproduction | We present a theoretical study of the radiative pion photoproduction on the
nucleon ($\gamma N \to \pi N \gamma'$) in the $\De$-resonance region, with the
aim to determine the magnetic dipole moment (MDM) of the $\Delta^+(1232)$. The
study is done within the framework of chiral effective-field theory where the
expansion is performed (to next-to-leading order) in the $\delta$
power-counting scheme which is an extension of chiral perturbation theory to
the $\Delta$-resonance energy region. We present the results for the absorptive
part of the $\Delta$ MDM, as well as perform a sensitivity study of the
dependence of $\gamma N \to \pi N \gamma'$ observables on the real part of the

709.4584 | New constraints on the Mid-IR EBL from the HESS discovery of VHE gamma
rays from 1ES 0229+200 | AIMS: To investigate the very high energy (VHE: >100 GeV) gamma-ray emission
from the high-frequency peaked BL Lac 1ES 0229+200.
METHODS: Observations of 1ES 0229+200 at energies above 580 GeV were
performed with the High Energy Stereoscopic System (HESS) in 2005 and 2006.
RESULTS: 1ES 0229+200 is discovered by HESS to be an emitter of VHE photons.
A signal is detected at the 6.6 sigma level in the HESS observations (41.8 h
live time). The integral flux above 580 GeV is (9.4 +- 1.5 {stat} +- 1.9
{syst}) x 10^{-13} cm^{-2} s^{-1}, corresponding to ~1.8% of the flux observed
from the Crab Nebula. The data show no evidence for significant variability on
any time scale. The observed spectrum is characterized by a hard power law
(Gamma = 2.50 +- 0.19 {stat} +- 0.10 {syst}) from 500 GeV to ~15 TeV.
CONCLUSIONS: The high-energy range and hardness of the observed spectrum,
coupled with the object's relatively large redshift (z=0.1396), enable the
strongest constraints so far on the density of the Extragalactic Background
Light (EBL) in the mid-infrared band. Assuming that the emitted spectrum is not
harder than Gamma_{int} ~ 1.5, the HESS data support an EBL spectrum ~
lambda^{-1} and density close to the lower limit from source counts measured by
Spitzer, confirming the previous indications from the HEGRA data of 1ES
1426+428 (z=0.129). Irrespective of the EBL models used, the intrinsic spectrum
of 1ES 0229+200 is hard, thus locating the high-energy peak of its spectral
energy distribution above a few TeV.

709.4585 | Coulomb gauge studies of SU(3) Yang-Mills theory on the lattice | We study the infrared behaviour of lattice SU(3) Yang-Mills theory in Coulomb
gauge in terms of the ghost propagator, the Coulomb potential and the
transversal and the time-time component of the equal-time gluon propagator. In
particular, we focus on the Gribov problem and its impact on the observables.
We observe that the simulated annealing method is advantageous for fixing the
Coulomb gauge in large volumes. We study finite size and discretization
effects. While finite size effects can be controlled by the cone cut, and the
ghost propagator and the Coulomb potential become scaling functions with the
cylinder cut, the equal-time gluon propagator does not show scaling in the
considered range of the inverse coupling constant. The ghost propagator is
infrared enhanced. The Coulomb potential is now extended to considerably lower
momenta and shows a more complicated infrared regime. The Coulomb string
tension satisfies Zwanziger's inequality, but its estimate can be considered

709.4588 | m-Mode Regularization Scheme for the Self Force in Kerr Spacetime | We present a new, simple method for calculating the scalar, electromagnetic,
and gravitational self forces acting on particles in orbit around a Kerr black
hole. The standard ``mode-sum regularization'' approach for self-force
calculations relies on a decomposition of the full (retarded) perturbation
field into multipole modes, followed by the application of a certain
mode-by-mode regularization procedure. In recent years several groups have
developed numerical codes for calculating black hole perturbations directly in
2+1 dimensions (i.e., decomposing the azimuthal dependence into $m$-modes, but
refraining from a full multipole decomposition). Here we formulate a practical
scheme for constructing the self force directly from the 2+1-dimensional
$m$-modes. While the standard mode-sum method is serving well in calculations

been developed which allow in an all-electric manner to determine the plane of
polarization of linearly polarized radiation and the ellipticity of
elliptically polarized radiation, respectively. The operation of the detectors
is based on photogalvanic effects in semiconductor quantum well structures of

709.4591 | Theoretical study of molecular electronic excitations and optical
transitions of C60 | We report results on ab initio calculations of excited states of the
fullerene molecule by using configuration interaction (CI) approach with singly
excited determinants (SCI). We have used both the experimental geometry and the
one optimized by the density functional method and worked with basis sets at
the cc-pVTZ and aug-cc-pVTZ level. Contrary to the early SCI semiempirical
calculations, we find that two lowest $^1 T_{1u} \leftarrow {}^1 A_g$ electron
optical lines are situated at relatively high energies of ~5.8 eV (214 nm) and
~6.3 eV (197 nm). These two lines originate from two $^1 T_{1u} \leftarrow {}^1
A_g$ transitions: from HOMO to (LUMO+1) ($6h_u \to 3t_{1g}$) and from (HOMO--1)
to LUMO ($10h_g \to 7t_{1u}$). The lowest molecular excitation, which is the $1
^3 T_{2g}$ level, is found at ~2.5 eV. Inclusion of doubly excited determinants
(SDCI) leads only to minor corrections to this picture. We discuss possible

709.4593 | Gamma Ray Spectrum from Gravitino Dark Matter Decay | Gravitinos are very promising candidates for the cold dark matter of the
Universe. Interestingly, to achieve a sufficiently long gravitino lifetime,
R-parity conservation is not required, thus preventing any dangerous
cosmological influence of the next-to-lightest supersymmetric particle. When
R-parity is violated, gravitinos decay into photons and other particles with a
lifetime much longer than the age of the Universe, producing a diffuse gamma
ray flux with a characteristic spectrum that could be measured in future
experiments, like GLAST or AMS-02. In this letter we compute the energy
spectrum of photons from gravitino decay and discuss its main qualitative
features.

709.4595 | Worldline Approach to Chiral Fermions | We propose to apply ``worldline numerics'' to a numerical calculation of
quark determinants. The Gross-Neveu model with a U(1) chiral symmetry is
considered as a first test. The worldline approach allows for an analytic
renormalisation, and only finite parts of the determinant require a numerical
calculation. It is shown that the discretisation of the worldlines, which is
central to the numerical treatment, preserves chiral symmetry exactly.
Numerical results for a kink configuration as a scalar background field are
shown and compared with analytical results. The case of finite fermion chemical
potential is also briefly discussed.

709.4596 | Ground state fidelity from tensor network representations | For any D-dimensional quantum lattice system, the fidelity between two ground
state many-body wave functions is mapped onto the partition function of a
D-dimensional classical statistical vertex lattice model with the same lattice
geometry. The fidelity per lattice site, analogous to the free energy per site,
is well-defined in the thermodynamic limit and can be used to characterize the
phase diagram of the model. We explain how to compute the fidelity per site in
the context of tensor network algorithms, and demonstrate the approach by

709.4597 | Some Aspects of Intermediate mass black holes | There is a lot of current astrophysical evidence and interest in intermediate
mass black holes, ranging from a few hundred to several thousand solar masses.
The active galaxy M82 and the globular cluster in M31, for example, are known
to host such objects. Here we discuss several aspects of intermediate mass
black holes such as their expected luminosity, spectral nature of radiation,
associated jets, etc. We also discuss possible scenarios for their formation
including the effects of dynamical friction, gravitational radiation, etc. We
also consider their formation in the early universe and also discuss the
possibility of supermassive black holes forming from mergers of several
intermediate mass black holes and compare the relevant time scales involved
with other scenarios.

rise to a representation of Nichols-Woronowicz algebras associated to Weyl

709.46 | Twisted Hopf symmetries of canonical noncommutative spacetimes and the
no-pure-boost principle | We study the twisted-Hopf-algebra symmetries of observer-independent
canonical spacetime noncommutativity, for which the commutators of the
spacetime coordinates take the form [x^{mu},x^{nu}]=i theta^{mu nu} with
observer-independent (and coordinate-independent) theta^{mu nu}. We find that
it is necessary to introduce nontrivial commutators between transformation
parameters and spacetime coordinates, and that the form of these commutators
implies that all symmetry transformations must include a translation component.
We show that with our noncommutative transformation parameters the Noether
analysis of the symmetries is straightforward, and we compare our
canonical-noncommutativity results with the structure of the conserved charges
and the "no-pure-boost" requirement derived in a previous study of
kappa-Minkowski noncommutativity. We also verify that, while at intermediate
stages of the analysis we do find terms that depend on the ordering convention
adopted in setting up the Weyl map, the final result for the conserved charges

709.4601 | Multiple stellar populations in Globular Clusters: collection of
information from the Horizontal Branch | The majority of the inhomogeneities in the chemical composition of Globular
Cluster (GC) stars appear due to primordial enrichment by hot-CNO cycled
material processed in stars belonging to a first stellar generation. Either
massive AGB envelopes subject to hot bottom burning, or the envelopes of
massive fastly rotating stars could be the progenitors. In both cases, the
stars showing chemical anomalies must have also enhanced helium abundance, and
we have proposed that this higher helium could be at the basis of the many
different morphologies of GC horizontal branches (HB) for similar ages and
metallicities. The helium variations have been beautifully confirmed by the
splitting of the main sequence in the clusters omega Cen and NGC 2808, but this
effect can show up only for somewhat extreme helium abundances. Therefore it is
important to go on using the HB morphology to infer the number ratio of the
first to the second generation in as many clusters as possible. We exemplify
how it is possible to infer the presence of a He-rich stellar component in
different clusters thanks to different HB features (gaps, RR Lyr periods and
period distribution, ratio of blue to red stars, blue tails). In many clusters
at least 50% of the stars belong to the second stellar generation, and in some
cases we suspect that the stars might all belong to the second generation. We
shortly examine the problem of the initial mass function required to achieve
the observed number ratios and conclude that: 1) the initial cluster must have
been much more massive than today's cluster, and 2) formation of the second
stellar generation mainly in the central regions of the cluster may help in
obtaining the desired values.

709.4602 | Multi-wavelength Observations of PG 1553+113 with HESS | Very high energy (VHE; >100 GeV) gamma-ray observations of PG 1553+113 were
made with the High Energy Stereoscopic System (HESS) in 2005 and 2006. A strong
signal, ~10 standard deviations, is detected by HESS during the 2 years of
observations (24.8 hours live time). The time-averaged energy spectrum,
measured between 225 GeV to ~1.3 TeV, is characterized by a very steep power
law (photon index of Gamma = (4.5 +- 0.3 {stat} +- 0.1 {syst}). The integral
flux above 300 GeV is ~3.4% of the Crab Nebula flux and shows no evidence for
any variations, on any time scale. H+K (1.45-2.45 micron) spectroscopy of PG
1553+113 was performed in March 2006 with SINFONI, an integral field

Theories | The quantum action (dynamical) principle is exploited to investigate the
nature and origin of the Faddeev-Popov (FP) factor in gauge theories without
recourse to path integrals. Gauge invariant as well as gauge non-invariant
interactions are considered to show that the FP factor needs to be modified in
more general cases and expressions for these modifications are derived. In
particular we show that a gauge invariant theory does not necessarily imply the
familiar FP factor for proper quantization.

709.4605 | Superconformal spaces and implications for superstrings | We clarify some properties of projective superspace by using a manifestly
superconformal notation. In particular, we analyze the N=2 scalar multiplet in
detail, including its action, and the propagator and its super-Schwinger
parameters. The internal symmetry is taken to be noncompact (after Wick
rotation), allowing boundary conditions that preserve it off shell.

709.4606 | A photometric study of Be stars located in the seismology fields of
COROT | Context: In preparation for the COROT mission, an exhaustive photometric
study of Be stars located in the seismology fields of the COROT mission has
been performed. The very precise and long-time-spanned photometric observations
gathered by the COROT satellite will give important clues of the origin of the
Be phenomenon.
Aims: The aim of this work is to find short-period variable Be stars located
in the seismology fields of COROT and to study and characterise their
pulsational properties.
Methods: Light curves obtained at the Observatorio de Sierra Nevada together
with data from Hipparcos and ASAS-3 of a total of 84 Be stars have been
analysed in order to search for short-term variations. We have applied standard
Fourier techniques and non-linear least-square fitting to the time series.
Results: We have found 7 multiperiodic, 21 mono-periodic and 26 non-variable
Be stars. Short-term variability has been detected in 74% of early-type Be
stars and in 31% of mid- to late-type Be stars. We have shown that non-radial
pulsations are most frequent among Be stars than in slow-rotating B stars of
the same spectral range.

Lac PKS 2155-304 has been monitored with the High Energy Stereoscopic System
(HESS). An extreme gamma-ray outburst was detected in the early hours of July
28, 2006 (MJD 53944). The average flux above 200 GeV observed during this
outburst is ~7 times the flux observed from the Crab Nebula above the same
threshold. Peak fluxes are measured with one-minute time scale resolution at
more than twice this average value. Variability is seen up to ~600 s in the
Fourier power spectrum, and well-resolved bursts varying on time scales of ~200
seconds are observed. There are no strong indications for spectral variability
within the data. Assuming the emission region has a size comparable to the
Schwarzschild radius of a ~10^9 solar mass black hole, Doppler factors greater
than 100 are required to accommodate the observed variability time scales.

provide estimation of the frequency of the lowest compressional mode and
compare it to analytical results derived using harmonic approach in the high

and conclude that local properties and energy are the same at zero temperature.
A question of to which extent the dipolar potential can be treated long- or

structures, analyzing the exact lattice regularized model. We derive
algorithmically all higher conserved quantities $C_n, n=1,2,...$ of this
integrable DSG model, focusing explicitly on the contribution of the defect
point to each $C_n$. The bridging condition across the defect, defined through
the B\"acklund transformation is found to induce creation or annihilation of a
soliton by the defect point or its preservation with a phase shift.

to be equally effective. In addition, we show that another leading approach
developed for the same purpose, namely, relative multifractal analysis, can be
considered as a special case of JPFA at a particular parameter setting.

709.4613 | Asteroseismology and Interferometry | Asteroseismology provides us with a unique opportunity to improve our
understanding of stellar structure and evolution. Recent developments,
including the first systematic studies of solar-like pulsators, have boosted
the impact of this field of research within Astrophysics and have led to a
significant increase in the size of the research community. In the present
paper we start by reviewing the basic observational and theoretical properties
of classical and solar-like pulsators and present results from some of the most
recent and outstanding studies of these stars. We centre our review on those
classes of pulsators for which interferometric studies are expected to provide
a significant input. We discuss current limitations to asteroseismic studies,
including difficulties in mode identification and in the accurate determination
of global parameters of pulsating stars, and, after a brief review of those
aspects of interferometry that are most relevant in this context, anticipate
how interferometric observations may contribute to overcome these limitations.
Moreover, we present results of recent pilot studies of pulsating stars
involving both asteroseismic and interferometric constraints and look into the
future, summarizing ongoing efforts concerning the development of future
instruments and satellite missions which are expected to have an impact in this
field of research.

709.4614 | Galaxy Bulges at Mid and High-Redshift | Bulges are a major galaxy component in the nearby universe, and are one of
the primary features that differentiates and defines galaxies. The origin of
bulges can be directly probed in part by examining distant galaxies to search
for high redshift bulges, and to study the properties of bulges in formation.
We review the evidence for bulges at high redshift in this article, and how by
studying bulges through a variety of approaches, including morphological,
colour, and stellar mass selection, we can determine when and how these systems
assembled. We argue that the majority of the most massive 'classical' bulges
are in place by z ~ 1.5 - 2, and likely formed very early through major
mergers. Other, likely lower mass, bulges form through a secular process along
with their disks. Direct observations suggest that these two formation
processes are occurring, as spheroids are commonly seen at z > 1, as are disks
and spiral galaxies in the form of luminous diffuse objects, clump-clusters,

| astro-ph | bulges are a major galaxy component in the nearby universe and are one of the primary features that differentiates and defines galaxies the origin of bulges can be directly probed in part by examining distant galaxies to search for high redshift bulges and to study the properties of bulges in formation we review the evidence for bulges at high redshift in this article and how by studying bulges through a variety of approaches including morphological colour and stellar mass selection we can determine when and how these systems assembled we argue that the majority of the most massive classical bulges are in place by z 15 2 and likely formed very early through major mergers other likely lower mass bulges form through a secular process along with their disks direct observations suggest that these two formation processes are occurring as spheroids are commonly seen at z 1 as are disks and spiral galaxies in the form of luminous diffuse objects clumpclusters and chain galaxies however bulgedisk systems are relatively rare until z 1 suggesting that this structural assembly occurred relatively late | [['bulges', 'are', 'a', 'major', 'galaxy', 'component', 'in', 'the', 'nearby', 'universe', 'and', 'are', 'one', 'of', 'the', 'primary', 'features', 'that', 'differentiates', 'and', 'defines', 'galaxies', 'the', 'origin', 'of', 'bulges', 'can', 'be', 'directly', 'probed', 'in', 'part', 'by', 'examining', 'distant', 'galaxies', 'to', 'search', 'for', 'high', 'redshift', 'bulges', 'and', 'to', 'study', 'the', 'properties', 'of', 'bulges', 'in', 'formation', 'we', 'review', 'the', 'evidence', 'for', 'bulges', 'at', 'high', 'redshift', 'in', 'this', 'article', 'and', 'how', 'by', 'studying', 'bulges', 'through', 'a', 'variety', 'of', 'approaches', 'including', 'morphological', 'colour', 'and', 'stellar', 'mass', 'selection', 'we', 'can', 'determine', 'when', 'and', 'how', 'these', 'systems', 'assembled', 'we', 'argue', 'that', 'the', 'majority', 'of', 'the', 'most', 'massive', 'classical', 'bulges', 'are', 'in', 'place', 'by', 'z', '15', '2', 'and', 'likely', 'formed', 'very', 'early', 'through', 'major', 'mergers', 'other', 'likely', 'lower', 'mass', 'bulges', 'form', 'through', 'a', 'secular', 'process', 'along', 'with', 'their', 'disks', 'direct', 'observations', 'suggest', 'that', 'these', 'two', 'formation', 'processes', 'are', 'occurring', 'as', 'spheroids', 'are', 'commonly', 'seen', 'at', 'z', '1', 'as', 'are', 'disks', 'and', 'spiral', 'galaxies', 'in', 'the', 'form', 'of', 'luminous', 'diffuse', 'objects', 'clumpclusters', 'and', 'chain', 'galaxies', 'however', 'bulgedisk', 'systems', 'are', 'relatively', 'rare', 'until', 'z', '1', 'suggesting', 'that', 'this', 'structural', 'assembly', 'occurred', 'relatively', 'late']] | [-0.08592769514200174, 0.126779560050151, -0.07284860112316285, 0.14756337168353437, -0.06629312211233708, -0.05453951723304474, -0.009574274681896592, 0.4468939002085891, -0.1526969574268959, -0.3332946227863431, 0.09017398133033162, -0.2647562749890818, -0.10644688287284225, 0.20065150118168984, -0.009800747083500028, -0.04511188111048088, 0.04109060865206023, -0.13804690605805567, -0.02393553331672188, -0.30876386836235825, 0.3405936485395715, 0.02380404401337728, 0.13371904044567298, -0.09788336419991941, 0.033358626938166304, -0.07051299502038294, -0.08693056057931649, -0.026388786559821003, -0.15798837724869372, 0.02868916468643066, 0.2817722582568725, 0.1402733189247859, 0.26113079177319176, -0.3930423971601865, -0.17031073074322195, 0.08750686495720099, 0.272149090280032, 0.07247942709752048, -0.1358496903700547, -0.22552703379963834, 0.1271710390157144, -0.1390332284637326, -0.11266474632753266, 0.045436392445117234, 0.027818682956664512, 0.03057965415581647, -0.1603363786293711, 0.1850286458444316, 0.08989227958178768, 0.08857391410403781, -0.05942695606111859, -0.09151162248518732, -0.09114425886784577, 0.0875866486401517, 0.04870874881016789, 0.058240804970005736, 0.24539511147369114, -0.17223352543595766, -0.07306902689031429, 0.4315473705633647, -0.008672056594837664, -0.018658686227475605, 0.30300488730685576, -0.23359196817036718, -0.19709630538968162, 0.09021108750538487, 0.19244897169862976, 0.08236837897501471, -0.15506509732521306, -0.0031281319320745145, 0.043774758691951215, 0.15762549995237754, 0.024407938406026612, 0.0666867285385605, 0.3743024593219161, 0.09354043750790879, -0.011139725163553117, 0.08021223408448147, -0.10648663075278617, -0.0632283081404037, -0.2130404852783411, -0.1456451947464504, -0.12447676898963335, 0.07529224412282928, -0.12842868749519565, -0.09435849710134789, 0.312616632744256, 0.06045458617041832, 0.28665851810947063, 0.061170742652999856, 0.27141192157481175, 0.050781072768020546, 0.14853400779344764, 0.08699066168757984, 0.298202046582527, 0.14874521766323595, 0.037278701279622815, -0.17765237774389486, 0.09120989209235025, -0.010123588162888256] |
709.4615 | Comment on ``Passage Times for Unbiased Polymer Translocation through a
Narrow Pore'' | One of the most fundamental quantities associated with polymer translocation
through a nanopore is the translocation time $\tau$ and its dependence on the
chain length $N$. Our simulation results based on both the bond fluctuation
Monte Carlo and Molecular Dynamics methods confirm the original prediction
$\tau\sim N^{2\nu+1}$, which scales in the same manner as the Rouse relaxation
time of the chain except for a larger prefactor, and invalidates other scaling
claims.

states for Loop Quantum Gravity, for the gauge group U(1). This is done by
projecting the corresponding complexifier coherent states, which have been
applied in numerous occasions to investigate the semiclassical limit of the
kinematical sector, to the gauge-invariant Hilbert space. This being the first
step to construct physical coherent states, we arrive at a set of
gauge-invariant states that approximate well the gauge-invariant degrees of
freedom of abelian LQG. Furthermore, these states turn out to encode explicit
information about the graph topology, and show the same pleasant peakedness
properties known from the gauge-variant complexifier coherent states.

709.462 | Mott transition in one dimension: Benchmarking dynamical cluster
approaches | The variational cluster approach (VCA) is applied to the one-dimensional
Hubbard model at zero temperature using clusters (chains) of up to ten sites
with full diagonalization and the Lanczos method as cluster solver. Within the
framework of the self-energy-functional theory (SFT), different cluster
reference systems with and without bath degrees of freedom, in different
topologies and with different sets of variational parameters are considered.
Static and one-particle dynamical quantities are calculated for half-filling as
a function of U as well as for fixed U as a function of the chemical potential
to study the interaction- and filling-dependent metal-insulator (Mott)
transition. The recently developed Q-matrix technique is used to compute the
SFT grand potential. For benchmarking purposes we compare the VCA results with
exact results available from the Bethe ansatz, with essentially exact dynamical
DMRG data, with (cellular) dynamical mean-field theory and full diagonalization
of isolated Hubbard chains. Several issues are discussed including convergence
of the results with cluster size, the ability of cluster approaches to access
the critical regime of the Mott transition, efficiency in the optimization of
correlated-site vs. bath-site parameters and of multi-dimensional parameter
optimization. We also study the role of bath sites for the description of
excitation properties and as charge reservoirs for the description of filling
dependencies. The VCA turns out to be a computationally cheap method which is
competitive with established cluster approaches.

Stereoscopic System (H.E.S.S.), an array of four Imaging Cherenkov Telescopes
located in Namibia and dedicated to the observations of gamma-rays above 100
GeV. The angular resolution of <0.1 degree and the large field of view of
H.E.S.S. (5 degrees diameter) are well adapted to studying the morphology of
the object in very high energy gamma-rays, which exhibits a remarkably thin
shell very similar to the features observed in the radio range and in X-rays.
The spectral analysis of the source from 300 GeV to 20 TeV will be presented.
Finally, the possible origins of the very high energy gamma-ray emission
(Inverse Compton scattering by electrons or the decay of neutral pions produced
by proton interactions) will be discussed, on the basis of morphological and
spectral features obtained at different wavelengths.

709.4622 | Dynamics and Hadronization at intermediate transverse momentum at RHIC | The ultra-relativistic heavy-ion program at RHIC has shown that at
intermediate transverse momenta ($p_T \simeq 2$-6 GeV) standard (independent)
parton fragmentation can neither describe the observed baryon-to-meson ratios
nor the empirical scaling of the hadronic elliptic flow ($v_2$) according to
the number of valence quarks. Both aspects find instead a natural explanation
in a coalescence plus fragmentation approach to hadronization. After a brief
review of the main results for light quarks, we focus on heavy quarks showing
that a combined fragmentation and quark-coalescence framework is relevant also
here. Moreover, within relativistic Langevin simulations we find evidence for
the importance of heavy-light resonances in the Quark-Gluon Plasma (QGP) to
explain the strong energy loss and collective flow of heavy-quark spectra as
inferred from non-photonic electron observables. Such heavy-light resonances

709.4623 | Low energy polarization sensitivity of the Gas Pixel Detector | An X-ray photoelectric polarimeter based on the Gas Pixel Detector has been
proposed to be included in many upcoming space missions to fill the gap of
about 30 years from the first (and to date only) positive measurement of
polarized X-ray emission from an astrophysical source. The estimated
sensitivity of the current prototype peaks at an energy of about 3 keV, but the
lack of readily available polarized sources in this energy range has prevented
the measurement of detector polarimetric performances.
In this paper we present the measurement of the Gas Pixel Detector
polarimetric sensitivity at energies of a few keV and the new, light, compact
and transportable polarized source that was devised and built to this aim.
Polarized photons are produced, from unpolarized radiation generated with an
X-ray tube, by means of Bragg diffraction at nearly 45 degrees.
The employment of mosaic graphite and flat aluminum crystals allow the
production of nearly completely polarized photons at 2.6, 3.7 and 5.2 keV from
the diffraction of unpolarized continuum or line emission. The measured
modulation factor of the Gas Pixel Detector at these energies is in good
agreement with the estimates derived from a Monte Carlo software, which was up
to now employed for driving the development of the instrument and for
estimating its low energy sensitivity. In this paper we present the excellent
polarimetric performance of the Gas Pixel Detector at energies where the peak
sensitivity is expected. These measurements not only support our previous
claims of high sensitivity but confirm the feasibility of astrophysical X-ray
photoelectric polarimetry.

709.4624 | Leptogenesis with exclusively low-energy CP Violation in the Context of
Minimal Lepton Flavour Violation | We analyze lepton flavour violation (LFV) and the generation of the observed
baryon-antibaryon asymmetry of the Universe (BAU) within a generalized minimal
lepton flavour violation framework with three quasi-degenerate heavy Majorana
neutrinos. The BAU which is obtained through radiative resonant leptogenesis
can successfully be generated widely independent of the Majorana scale in this
scenario and flavour effects are found to be relevant. Then we discuss the
specific case in which CP violation is exclusively present at low-energies (a
real R matrix) in the flavour sensitive temperature regime. Successful

709.4627 | Statistical analysis of neutrino events from SN1987A neutrino burst:
estimation of the electron antineutrino mass | The method of the statistical sample moments was used for the analysis of
neutrino events from SN1987A burst in Cherenkov detectors. In particular the
coefficients of correlation $Q(E,t)$ between the energies $E$ of electron
antineutrinos $\bar \nu_e$ emitted by star and the ejection instants $t$ of
$\bar \nu_e$ for neutrino events recorded by Cherenkov water detectors of KII
and IMB collaborations were calculated. $Q(E,t)$ values depend on the assumed
mass of $\bar \nu_e$. Modern model of the gravitational stellar core collapse
with an accretion phase predicts the low level of such correlation $<Q(E,t)>$
averaged with respect to neutrino burst. On condition that empirical $Q(E,t)$
values equal the theoretical model quantities $<Q(E,t)>$ one can obtain
$22\pm10 eV/c^{2}$ as an estimate of the nonzero $\bar \nu_e$ mass. The error
of this estimate implies that $\bar \nu_e$ mass less than $2 eV/c^2$ is
unlikely. The laboratry data of the tritium $\beta$-decay agree adequately with

709.4628 | Precision Lattice Calculation of D and Ds decay constants | We present a determination of the decay constants of the $D$ and $D_s$ mesons
from lattice QCD, each with a total error of about 2%, approximately a factor
of three better than previous calculations. We have been able to achieve this
through the use of a highly improved discretization of QCD for charm quarks,
coupled to gauge configurations generated by the MILC collaboration that
include the full effect of sea u, d, and s quarks. We have results for a range
of u/d masses down to m_s/5 and three values of the lattice spacing, which
allow us to perform accurate continuum and chiral extrapolations. We fix the
charm quark mass to give the experimental value of the \eta_c mass, and then a
stringent test of our approach is the fact that we obtain correct (and
accurate) values for the mass of the D and D_s mesons. We compare f_D and
f_{D_s} with f_K and f_\pi, and using experiment determine corresponding CKM
elements with good precision.

the overlap operator at nonzero quark chemical potential. In particular, we
show that the relation between the anomaly and the index of the overlap

709.4631 | Dynamics of the triple contact line on a non-isothermal heater at
partial wetting | The dynamics of the triple gas-liquid-solid contact line is analysed for the
case where the gas is the saturated vapour corresponding to the liquid, like in
the vapour bubble in boiling. It is shown that even small superheating (with
respect to the saturation temperature) causes evaporation of the adsorption
liquid film and the true triple contact is established. It is shown that the
hydrodynamic contact line singularity cannot be relaxed with the Navier slip
condition under such circumstances. Augmented with the second derivative slip
condition is proposed to be applied. For the partial wetting conditions, a
non-stationary contact line problem where the contact line motion is caused by
evaporation or condensation is treated in the lubrication approximation in the
vicinity of the contact line. High heat fluxes in this region require the
transient heat conduction inside the heater to be accounted for. Two 2D
problems, those of drop retraction with no phase change and of drop evaporation

compactified on a 7D toroidal manifold is obtained. It describes a
supermembrane evolving in a 4d Minkowski space-time. The action is invariant
under additional symmetries in comparison to the supermembrane on a Minkowski
target space. The hamiltonian in the LCG is invariant under conformal
transformations on the Riemann surface base manifold. The spectrum of the
regularized hamiltonian is discrete with finite multiplicity. Its resolvent is
compact. Susy is spontaneously broken, due to the topological central charge
condition, to four supersymmetries in 4D, the vacuum belongs to an N=1
supermultiplet. When assuming the target-space to be an isotropic 7-tori, the
potential does not contain any flat direction, it is stable on the moduli space
of parameters.
