712.1879 | Ultrafast Electron-Phonon Decoupling in Graphite | We report the ultrafast dynamics of the 47.4 THz coherent phonons of graphite
interacting with a photoinduced non-equilibrium electron-hole plasma. Unlike
conventional materials, upon photoexcitation the phonon frequency of graphite
upshifts, and within a few picoseconds relaxes to the stationary value. Our
first-principles density functional calculations demonstrate that the phonon
stiffening stems from the light-induced decoupling of the non-adiabatic
electron-phonon interaction by creating the non-equilibrium electron-hole
plasma. Time-resolved vibrational spectroscopy provides a window on the
ultrafast non-equilibrium electron dynamics.

712.188 | Normal Forms, K3 Surface Moduli, and Modular Parametrizations | The geometric objects of study in this paper are K3 surfaces which admit a
polarization by the unique even unimodular lattice of signature (1,17). A
standard Hodge-theoretic observation about this special class of K3 surfaces is
that their polarized Hodge structures are identical with the polarized Hodge
structures of abelian surfaces that are cartesian products of elliptic curves.
Earlier work of the first two authors gives an explicit normal form and
construction of the moduli space for these surfaces. In the present work, this
normal form is used to derive Picard-Fuchs differential equations satisfied by
periods of these surfaces. We also investigate the subloci of the moduli space
on which the polarization is enhanced. In these cases, we derive information
about the Picard-Fuchs differential equations satisfied by periods of these
subfamilies, and we relate this information to the theory of genus zero
quotients of the upper half-plane by Moonshine groups. For comparison, we also
examine the analogous theory for elliptic curves in Weierstrass form.

712.1881 | Conformal transformation in the scalar-tensor theory applied to the
accelerating universe | The scalar-tensor theory is plagued by nagging questions if different
conformal frames, in particular the Jordan and Einstein conformal frames, are
equivalent to each other. As a closely related question, there are opposing
views on which of the two conformal frames is physically acceptable.
Reinforcing our previous claims, we offer replies based on a cosmological model
of the scalar-tensor theory, believed to be a promising theory for
understanding the accelerating universe, as well as today's version of the
cosmological constant problem. Exploiting the advantage that this model admits
analytical asymptotic solutions, our argument does not depend on whether the
underlying theory is invariant under conformal transformations. Our argument
provides partial support for the claimed "equivalence," but we also present
examples that require more careful analyses exploiting field equations. We also
point out that the Jordan conformal frame is suitable for an interpretation in
terms of unification theories in physics, for example, string theory and the
Kaluza-Klein approach, while the Einstein conformal frame may be acceptable as
a physical conformal frame under two conditions: (i) the simplest constant
$\Lambda$ term in the Lagrangian in the Jordan conformal frame; (ii) the
revised form of the conventional Brans-Dicke model based on the validity of
weak equivalence principle.

B_{u,d}(bar) to DP decays are used to extract the effective Wilson coefficients

This information is used to predict rates of nineteen B_{s}(bar) to DP and
B_{u,d,s}(bar) to D(bar)P decay modes, including modes of interests in the
gamma/phi_3 program. Many decay rates are found to be enhanced. In particular,
the B_s(bar) to D0 K0 rate is predicted to be 8\times 10^{-4}, which could be
measured soon. The rescattering effects on the corresponding B_{u,d,s}(bar) to
D(bar)P, DP amplitude ratios r_B, r_{B_s}, and the relative strong phases
delta_B, delta_{B_s} are studied. Although the decay rates are enhanced in most

712.1883 | Parametrization and Stress-Energy-Momentum Tensors in Metric Field
Theories | We give an exposition of the parametrization method of Kuchar [1973] in the
context of the multisymplectic approach to field theory, as presented in Gotay
and Marsden [2008a]. The purpose of the formalism developed herein is to make
any classical field theory, containing a metric as a sole background field,
generally covariant (that is, "parametrized," with the spacetime diffeomorphism
group as a symmetry group) as well as fully dynamic. This is accomplished by
introducing certain "covariance fields" as genuine dynamic fields. As we shall
see, the multimomenta conjugate to these new fields form the Piola-Kirchhoff
version of the stress-energy-momentum tensor field, and their Euler-Lagrange
equations are vacuously satisfied. Thus, these fields have no additional
physical content; they serve only to provide an efficient means of
parametrizing the theory. Our results are illustrated with two examples, namely
an electromagnetic field and a Klein-Gordon vector field, both on a background
spacetime.

712.1887 | Mid-infrared imaging of brown dwarfs in binary systems | Context: Brown dwarfs exhibit complex atmospheric signatures, and their
properties depend sensitively on effective temperature, surface gravity, and
metallicity. Several physical properties of brown dwarfs in binary systems can
be well inferred from the primary, and therefore allow to better constrain
their atmospheres.
Aims: We want to constrain atmospheric models of brown dwarfs in binary
systems using narrow-band mid-infrared photometry.
Methods: High spatial resolution and sensitivity is required to resolve the
components. Therefore we have obtained deep mid-infrared images of four close
binary systems with brown dwarf companions using VISIR at the VLT in three
narrow-band filters at 8.6, 10.5 and 11.25 micron.
Results: Three brown dwarfs companions (GJ 229B, HD 130948BC and HR 7329B)
were detected at 8.6micron. HD 130948BC was also observed at 10.5micron. We
finally place upper flux limits for the other narrow band filters with null
detections.
Conclusions: Our results are in general compatible with previous observations
and model expectations for these objects. For HD 130948BC, we conclude
photometric variability on a significance level of 2.8sigma based on repeated
observations. The bandpass around 10.5micron appears specifically well suited
for variability studies, and we speculate that either inhomogeneities in the
atmospheric NH3 distribution, or silicate absorption might cause its
time-variability.

binary systems with brown dwarf companions using visir at the vlt in three narrowband filters at 86 105 and 1125 micron results three brown dwarfs companions gj 229b hd 130948bc and hr 7329b were detected at 86micron hd 130948bc was also observed at 105micron we finally place upper flux limits for the other narrow band filters with null detections conclusions our results are in general compatible with previous observations and model expectations for these objects for hd 130948bc we conclude photometric variability on a significance level of 28sigma based on repeated observations the bandpass around 105micron appears specifically well suited for variability studies and we speculate that either inhomogeneities in the atmospheric nh3 distribution or silicate absorption might cause

712.1888 | Dynamical and evolutionary constraints on the nature and origin of
hypervelocity stars | In recent years several hypervelocity stars (HVSs) have been observed in the
halo of our Galaxy. Such stars are thought to be ejected through dynamical
interactions near the massive black hole (MBH) in the Galactic center. Three
scenarios have been suggested for their ejection; binary disruption by a MBH,
scattering by inspiraling IMBH and scattering by stellar BHs close to MBH.
These scenarios involve different stellar populations in the Galactic center.
Here we use observations of the Galactic center stellar population together
with dynamical and evolutionary arguments to obtain strong constraints on the
nature and origin of HVSs. We show that the IMBH inspiral scenario requires too
many (O(10^3)) main sequence B stars to exist close to the MBH (<0.01 pc) at
the time of inspiral, where current observations show O(10) such stars.
Scattering by SBHs also require too many B stars to be observed in the GC, but
it may contribute a small fraction of the currently observed HVSs. The binary
disruption scenario is still consistent with current observations. In addition
it is shown that recently suggested signatures for HVSs origin such as
hypervelocity binaries and slow rotating HVSs are much weaker than suggested
and require too large statistics. In addition, we show that due to the
conditions close to the MBH most binary star systems are not expected to
survive for long in this region. Consequently, unique stellar populations that
require long evolution in binaries are not expected to be ejected as HVSs in
the BHs scattering mechanisms (this may also be related to to the recently
observed asymmetry in the velocity distribution of HVSs).

712.1889 | Active one-way quantum computation with 2-photon 4-qubit cluster states | By using 2-photon 4-qubit cluster states we demonstrate deterministic one-way
quantum computation in single qubit rotation algorithm. In this operation
feed-forward measurements are automatically implemented by properly choosing
the measurement basis of the qubits, while Pauli error corrections are realized
by using two fast driven Pockels cells. We realized also a C-NOT gate for
equatorial qubits and a C-Phase gate for a generic target qubit. Our results

712.189 | Measurement of surface concentration of fluorophores using fluorescence
fluctuation spectroscopy | Fluorescence fluctuation spectroscopy is applied to study molecules, passing
through a small observation volume, usually subjected to diffusive or
convective motion in liquid phase. We suggest that such a technique could be
used to measure the areal absolute concentration of fluorophores deposited on a
substrate or imbedded in a thin film, with a resolution of a few micrometers.
The principle is to translate the solid substrate in front of a confocal
fluorescence microscope objective and to record the subsequent fluctuations of
the fluorescence intensity. The validity of this concept is investigated on
model substrates (fluorescent microspheres) and DNA biochips.

Bose-Einstein Condensate Past an Obstacle | Stability of dark solitons generated by a supersonic flow of Bose-Einstein
condensate past an obstacle is investigated. It is shown that in the reference
frame attached to the obstacle a transition occurs at some critical value of
the flow velocity from absolute instability of dark solitons to their
convective instability. This leads to decay of disturbances of solitons at
fixed distance from the obstacle and formation of effectively stable dark
solitons. This phenomenon explains surprising stability of the flow picture
that has been observed in numerical simulations.

712.1893 | Influence of random roughness on the Casimir force at small separations | The influence of random surface roughness of Au films on the Casimir force is
explored with atomic force microscopy in the plate-sphere geometry. The
experimental results are compared to theoretical predictions for separations
ranging between 20 and 200 nm. The optical response and roughness of the Au
films were measured and used as input in theoretical predictions. It is found
that at separations below 100 nm, the roughness effect is manifested through a
strong deviation from the normal scaling of the force with separation distance.
Moreover, deviations from theoretical predictions based on perturbation theory
can be larger than 100%.

712.1898 | Multiphoton Transitions in a Spin System Driven by Strong Bichromatic
Field | EPR transient nutation spectroscopy is used to measure the effective field
(Rabi frequency) for multiphoton transitions in a two-level spin system
bichromatically driven by a transverse microwave (MW) field and a longitudinal
radio-frequency (RF) field. The behavior of the effective field amplitude is
examined in the case of a relatively strong MW field, when the derivation of
the effective Hamiltonian cannot be reduced to first-order perturbation theory
in w_{1} / w_{rf} (w_{1} is the microwave Rabi frequency, w_{rf} is the RF
frequency). Experimental results are consistently interpreted by taking into
account the contributions of second and third order in w_{1} / w_{rf} evaluated
by Krylov-Bogolyubov-Mitropolsky averaging. In the case of inhomogeneously
broadened EPR line, the third-order correction modifies the nutation frequency,

nearby type Ic SN 2007gr are presented. The very early discovery (less than 5
days after the explosion) and the relatively short distance of the host galaxy
motivated an extensive observational campaign. SN 2007gr shows an average peak
luminosity but unusually narrow spectral lines and an almost flat photospheric
velocity profile. The detection of prominent carbon features in the spectra is
shown and suggest a wide range in carbon abundance in stripped-envelope
supernovae. SN 2007gr may be an important piece in the puzzle of the observed
diversity of CC SNe.

712.1901 | Progress in the Determination of Polarized PDFs and Higher Twist | The impact of the recent very precise CLAS and COMPASS g1/F1 data on
polarized parton densities and higher twist effects is discussed. It is
demonstrated that the low Q^2 CLAS data improve essentially our knowledge of
higher twist corrections to the spin structure function g1, while the large Q^2
COMPASS data influence mainly the strange quark and gluon polarizations. It is
also shown that the uncertainties in the determination of the polarized parton
densities are significantly reduced. We find also that the present inclusive

712.1903 | Cycles of random permutations with restricted cycle lengths | We prove some general results about the asymptotics of the distribution of
the number of cycles of given length of a random permutation whose distribution
is invariant under conjugation. These results were first established to be
applied in a forthcoming paper (Cycles of free words in several random
permutations with restricted cycles lengths), where we prove results about
cycles of random permutations which can be written as free words in several
independent random permutations. However, we also apply them here to prove
asymptotic results about random permutations with restricted cycle lengths.
More specifically, for $A$ a set of positive integers, we consider a random
permutation chosen uniformly among the permutations of $\{1,..., n\}$ which
have all their cycle lengths in $A$, and then let $n$ tend to infinity.
Improving slightly a recent result of Yakymiv (Random A-Permutations:
Convergence to a Poisson Process), we prove that under a general hypothesis on
$A$, the numbers of cycles with fixed lengths of this random permutation are
asymptotically independent and distributed according to Poisson distributions.
In the case where $A$ is finite, we prove that the behavior of these random
variables is completely different: cycles with length $\max A$ are predominant.

712.1904 | Probing the submillimetre number counts at f(850um) < 2mJy | We have conducted a submillimetre mapping survey of faint, gravitationally
lensed sources, where we have targeted twelve galaxy clusters and additionally
the NTT Deep Field. The total area surveyed is 71.5 arcmin^2 in the image
plane; correcting for gravitational lensing, the total area surveyed is 40
arcmin^2 in the source plane for a typical source redshift z=2.5. In the
deepest maps, an image plane depth of 1sigma r.m.s. ~0.8 mJy is reached. This
survey is the largest survey to date to reach such depths. In total 59 sources
were detected, including three multiply-imaged sources. The gravitational
lensing makes it possible to detect sources with flux density below the blank
field confusion limit. The lensing corrected fluxes ranges from 0.11 mJy to 19
mJy. After correcting for multiplicity there are 10 sources with fluxes <2 mJy
of which 7 have sub-mJy fluxes, doubling the number of such sources known.
Number counts are determined below the confusion limit. At 1 mJy the integrated
number count is ~10^4 deg^-2, and at 0.5 mJy it is ~2x10^4 deg^-2. Based on the
number counts, at a source plan flux limit of 0.1 mJy, essentially all of the
850um background emission has been resolved. The dominant contribution (> 50
per cent) to the integrated background arises from sources with fluxes S(850)
between 0.4 and 2.5 mJy, while the bright sources S(850) > 6mJy contribute only
10 per cent.

712.1905 | Analysis of anisotropy crossover due to oxygen in Pt/Co/MOx trilayer | Extraordinary Hall effect and X-ray spectroscopy measurements have been
performed on a series of Pt/Co/MOx trilayers (M=Al, Mg, Ta...) in order to
investigate the role of oxidation in the onset of perpendicular magnetic
anisotropy at the Co/MOx interface. It is observed that varying the oxidation
time modifies the magnetic properties of the Co layer, inducing a magnetic
anisotropy crossover from in-plane to out-of-plane. We focused on the influence
of plasma oxidation on Pt/Co/AlOx perpendicular magnetic anisotropy. The
interfacial electronic structure is analyzed via X-ray photoelectron
spectroscopy measurements. It is shown that the maximum of out-of-plane
magnetic anisotropy corresponds to the appearance of a significant density of
Co-O bondings at the Co/AlOx interface.

712.1906 | Suzaku observations of Markarian 335: evidence for a distributed
reflector | We report on a 151 ks net exposure Suzaku observation of the Narrow Line
Seyfert 1 galaxy Mrk 335. The 0.5-40 keV spectrum contains a broad Fe line, a
strong soft excess below about 2 keV and a Compton hump around 20-30 keV. We
find that a model consisting of a power law and two reflectors provides the
best fit to the time-averaged spectrum. In this model, an ionized, heavily
blurred, inner reflector produces most of the soft excess, while an almost
neutral outer reflector (outside ~40 r_g) produces most of the Fe line
emission. The spectral variability of the observation is characterised by
spectral hardening at very low count rates. In terms of our power-law +
two-reflector model it seems like this hardening is mainly caused by pivoting
of the power law. The rms spectrum of the entire observation has the curved
shape commonly observed in AGN, although the shape is significantly flatter
when an interval which does not contain any deep dip in the lightcurve is
considered. We also examine a previous 133 ks XMM-Newton observation of Mrk
335. We find that the XMM-Newton spectrum can be fitted with a similar
two-reflector model as the Suzaku data and we confirm that the rms spectrum of
the observation is flat. The flat rms spectra, as well as the high-energy data
from the Suzaku PIN detector, disfavour an absorption origin for the soft
excess in Mrk 335.

712.1907 | Dynamical evolution of the Gliese 581 planetary system | We address the issue of the dynamical evolution of the Gliese 581 planetary
system. It is crucial when considering the planets' habitability because the
secular evolution of the orbits may regulate their climate, even in the case
where the system is stable. We have numerically integrated the planetary system
over 10^8 yrs, starting from the present fitted solution. In all cases, the
system appears dynamically stable, even in close to pole-on configurations.
Only a limited range of inclinations can be excluded. The climate on the
planets is expected to be secularly stable, thus not precluding the development
of life. Gl 581 remains the best candidate for a planetary system with planets
that potentially bear primitive forms of life.

712.1908 | Quantum Zeno Effect in the Quantum Non-Demolition Detection of Itinerant
Photons | We analyze the detection of itinerant photons using a quantum non-demolition
(QND) measurement. We show that the backaction due to the continuous
measurement imposes a limit on the detector efficiency in such a scheme. We
illustrate this using a setup where signal photons have to enter a cavity in
order to be detected dispersively. In this approach, the measurement signal is
the phase shift imparted to an intense beam passing through a second cavity
mode. The restrictions on the fidelity are a consequence of the Quantum Zeno

712.191 | Distinguishing quantum from classical oscillations in a driven phase
qubit | Rabi oscillations are coherent transitions in a quantum two-level system
under the influence of a resonant perturbation, with a much lower frequency
dependent on the perturbation amplitude. These serve as one of the signatures
of quantum coherent evolution in mesoscopic systems. It was shown recently [N.
Gronbech-Jensen and M. Cirillo, Phys. Rev. Lett. 95, 067001 (2005)] that in
phase qubits (current-biased Josephson junctions) this effect can be mimicked
by classical oscillations arising due to the anharmonicity of the effective
potential. Nevertheless, we find qualitative differences between the classical
and quantum effect. First, while the quantum Rabi oscillations can be produced
by the subharmonics of the resonant frequency (multiphoton processes), the
classical effect also exists when the system is excited at the overtones.
Second, the shape of the resonance is, in the classical case,
characteristically asymmetric; while quantum resonances are described by
symmetric Lorentzians. Third, the anharmonicity of the potential results in the
negative shift of the resonant frequency in the classical case, in contrast to
the positive Bloch-Siegert shift in the quantum case. We show that in the
relevant range of parameters these features allow to confidently distinguish
the bona fide Rabi oscillations from their classical Doppelganger.

712.1913 | CMB polarization constraints on radiative feedback | We compute the imprints left on the CMB by two cosmic reionization models
consistent with current observations but characterized by alternative radiative
feedback prescriptions (suppression and filtering) resulting in a different
suppression of star formation in low-mass halos. The models imply different
ionization and thermal histories and 21 cm background signals. The derived
Comptonization, u, and free-free distortion, y_B, parameters are below current
observational limits for both models. However, the value of u = 1.69 * 10^-7
(9.65 * 10^-8) for the suppression (filtering) model is in the detectability
range of the next generation of CMB spectrum experiments. Through the dedicated
Boltzmann code CMBFAST, modified to include the above ionization histories, we
compute the CMB angular power spectrum (APS) of the TT, TE, and EE modes. For
the EE mode the differences between these models are significantly larger than
the cosmic and sampling variance over the multipole range l = 5-15, leaving a
good chance of discriminating between these feedback mechanisms with
forthcoming/future CMB polarization experiments. The main limitations come from
foreground contamination: it should be subtracted at per cent level in terms of
APS, a result potentially achievable by novel component separation techniques
and mapping of Galactic foreground.

712.1914 | Universality of REM-like aging in mean field spin glasses | Aging has become the paradigm to describe dynamical behavior of glassy
systems, and in particular spin glasses. Trap models have been introduced as
simple caricatures of effective dynamics of such systems. In this Letter we
show that in a wide class of mean field models and on a wide range of time
scales, aging occurs precisely as predicted by the REM-like trap model of
Bouchaud and Dean. This is the first rigorous result about aging in mean field
models except for the REM and the spherical model.

712.1915 | Ground State Hyperfine Structure of Muonic Helium Atom | On the basis of the perturbation theory in the fine structure constant
$\alpha$ and the ratio of the electron to muon masses we calculate one-loop
vacuum polarization and electron vertex corrections and the nuclear structure
corrections to the hyperfine splitting of the ground state of muonic helium
atom $(\mu e ^4_2He)$. We obtain total result for the ground state hyperfine
splitting $\Delta \nu^{hfs}=4465.526$ MHz which improves the previous
calculation of Lakdawala and Mohr due to the account of new corrections. The
remaining difference between the theoretical result and experimental value of
the hyperfine splitting equal to 0.522 MHz lies in the range of theoretical
error and requires the subsequent investigation of higher order corrections.

712.1917 | Are solar cycles predictable? | Various methods (or recipes) have been proposed to predict future solar
activity levels - with mixed success. Among these, some precursor methods based
upon quantities determined around or a few years before solar minimum have
provided rather high correlations with the strength of the following cycles.
Recently, data assimilation with an advection-dominated (flux-transport) dynamo
model has been proposed as a predictive tool, yielding remarkably high
correlation coefficients. After discussing the potential implications of these
results and the criticism that has been raised, we study the possible physical
origin(s) of the predictive skill provided by precursor and other methods. It
is found that the combination of the overlap of solar cycles and their
amplitude-dependent rise time (Waldmeier's rule) introduces correlations in the
sunspot number (or area) record, which account for the predictive skill of many
precursor methods. This explanation requires no direct physical relation
between the precursor quantity and the dynamo mechanism (in the sense of the
Babcock-Leighton scheme or otherwise).

712.1919 | Modelling the polarization dichotomy of Active Galactic Nuclei | I present polarization modelling of Active Galactic Nuclei in the optical/UV
range. The modelling is conducted using the Monte-Carlo radiative transfer code
Stokes, which self-consistently models the polarization signature of a complex
model arrangement for an active nucleus. In this work I include three different
scattering regions around the central source: an equatorial electron scattering
disk, an equatorial obscuring dusty torus, and polar electron scattering cones.
I investigate the resulting dependencies of the V-band polarization for
different optical depths of the scattering cones, different dust compositions

712.192 | Asymmetric phase diagram of mixed $CuInP_2(S_xSe_{1-x})_6$ crystals | In this article mixed CuInP$_2$(S$_x$Se$_{1-x}$)$_6$ crystals were
investigated by broadband dielectric spectroscopy (20 Hz - 3 GHz). From these
results the complete phase diagram has been obtained. In the middle part of the
phase diagram the dipolar glass phase has been observed. The phase diagram of
investigated crystals is strongly asymmetric - the decreasing of ferroelectric
phase transition temperatures in CuInP$_2$(S$_x$Se$_{1-x}$)$_6$ is much more
flat with small admixture of sulphur then with small admixture of selenium. In
boundary region between ferroelectric order and dipolar glass disorder with
small amount of sulphur at low temperatures the nonergodic relaxor phase
appears. The phase diagram was discussed in terms of random bonds and random
fields.

712.1921 | Collisionless relaxation in non-neutral plasmas | A theoretical framework is presented which allows to quantitatively predict
the final stationary state achieved by a non-neutral plasma during a process of
collisionless relaxation. As a specific application, the theory is used to
study relaxation of charged-particles beams. It is shown that a fully matched
beam relaxes to the Lynden-Bell distribution. However, when a mismatch is
present and the beam oscillates, parametric resonances lead to a core-halo
phase separation. The approach developed accounts for both the density and the
velocity distributions in the final stationary state.

prove moment bounds for the inverse of the empirical covariance matrix. Then we
deduce an asymptotic expression of the mean-squared error. In particular we
give a relation between the number of terms used to estimate the coefficients
and the number of past terms used for prediction, which ensures the L^2-sense
convergence of the predictor. Finally we prove a central limit theorem when our
predictor converges to the best linear predictor based on all the past.

NGC4945 and Circinus enables us to characterize the physical conditions and
compare them to previous local and high-z studies. We estimate temperature,
molecular density and column densities of CO and atomic carbon. Using model
predictions we give a range of estimated CO/C abundance ratios. Using the new
NANTEN2 4m sub-millimeter telescope in Pampa La Bola, Chile, we observed for
the first time CO 4-3 and [CI] 3P1-3 P0 at the centers of both galaxies at
linear scale of 682 pc and 732 pc respectively. We compute the cooling curves
of 12CO and 13CO using radiative transfer models and estimate the physical
conditions of CO and [CI]. The centers of NGC4945 and Circinus are very [CI]
bright objects, exhibiting [CI] 3P1 - 3 P0 luminosities of 91 and 67Kkms-1kpc2,
respectively. The [CI] 3P1-3 P0/CO 4-3 ratio of integrated intensities are
large at 1.2 in NGC4945 and 2.8 in Circinus. Combining previous CO J= 1-0, 2-1
and 3-2 and 13CO J= 1-0, 2-1 studies with our new observations, the radiative
transfer calculations give a range of densities, n(H2) = 10^3-3*104^cm-3, and a
wide range of kinetic temperatures, Tkin = 20 - 100K, depending on the density.
Future CO J= 7-6 and [CI] 2-1 observations will be important to resolve the
ambiguity in the physical conditions and confirm the model predictions.

712.1925 | Binding of Hypernuclei in the Latest Quark-Meson Coupling Model | The most recent development of the quark-meson coupling (QMC) model, in which
the effect of the mean scalar field in-medium on the hyperfine interaction is
also included self-consistently, is used to compute the properties of finite
hypernuclei. The calculations for $\Lambda$ and $\Xi$ hypernuclei are of
comparable quality to earlier QMC results without the additional parameter
needed there. Even more significantly, the additional repulsion associated with
the increased hyperfine interaction in-medium completely changes the
predictions for $\Sigma$ hypernuclei. Whereas in the earlier work they were
bound by an amount similar to $\Lambda$ hypernuclei, here they are unbound, in
qualitative agreement with the experimental absence of such states. The
equivalent non-relativistic potential felt by the $\Sigma$ is repulsive inside
the nuclear interior and weakly attractive in the nuclear surface, as suggested
by the analysis of $\Sigma$-atoms.

within a functional integral formulation. We concentrate on zero temperature,
where the Bogoliubov theory breaks down for strong couplings as well as for low
dimensional models. We find that the leading behavior of the occupation numbers
for small momentum is governed by a quadratic time derivative in the inverse
propagator that is not contained in the Bogoliubov theory. We propose to use a
functional renormalization group equation for the occupation numbers in order
to implement systematic non-perturbative extensions beyond the Bogoliubov
theory.

712.1927 | Quantum Hall system in Tao-Thouless limit | We consider spin-polarized electrons in a single Landau level on a torus. The
quantum Hall problem is mapped onto a one-dimensional lattice model with
lattice constant $2\pi/L_1$, where $L_1$ is a circumference of the torus (in
units of the magnetic length). In the Tao-Thouless limit, $L_1\to 0$, the
interacting many-electron problem is exactly diagonalized at any rational
filling factor $\nu=p/q\le 1$. For odd $q$, the ground state has the same
qualitative properties as a bulk ($L_1 \to \infty$) quantum Hall hierarchy
state and the lowest energy quasiparticle exitations have the same fractional
charges as in the bulk. These states are the $L_1 \to 0$ limits of the
Laughlin/Jain wave functions for filling fractions where these exist. We argue
that the exact solutions generically, for odd $q$, are continuously connected
to the two-dimensional bulk quantum Hall hierarchy states, {\it ie} that there
is no phase transition as $L_1 \to \infty$ for filling factors where such
states can be observed. For even denominator fractions, a phase transition
occurs as $L_1$ increases. For $\nu=1/2$ this leads to the system being mapped
onto a Luttinger liquid of neutral particles at small but finite $L_1$, this
then develops continuously into the composite fermion wave function that is
believed to describe the bulk $\nu=1/2$ system. The analysis generalizes to
non-abelian quantum Hall states.

712.1928 | Distribution of Edge Load in Scale-free Trees | Node betweenness has been studied recently by a number of authors, but until
now less attention has been paid to edge betweenness. In this paper, we present
an exact analytic study of edge betweenness in evolving scale-free and
non-scale-free trees. We aim at the probability distribution of edge
betweenness under the condition that a local property, the in-degree of the
``younger'' node of a randomly selected edge, is known. En route to the
conditional distribution of edge betweenness the exact joint distribution of
cluster size and in-degree, and its one dimensional marginal distributions have
been presented in the paper as well. From the derived probability distributions
the expectation values of different quantities have been calculated. Our
results provide an exact solution not only for infinite, but for finite
networks as well.

712.1931 | Probing clumpy stellar winds with a neutron-star | INTEGRAL tripled the number of super-giant high-mass X-ray binaries (sgHMXB)
known in the Galaxy by revealing absorbed and fast transient (SFXT) systems.
Quantitative constraints on the wind clumping of massive stars can be obtained
from the study of the hard X-ray variability of SFXT. A large fraction of the
hard X-ray emission is emitted in the form of flares with a typical duration of
3 ksec, frequency of 7 days and luminosity of 1E36 ergs/s. Such flares are most
probably emitted by the interaction of a compact object orbiting at ~ 10 R*
with wind clumps (1E(22-23) g) representing a large fraction of the stellar
mass-loss rate. The density ratio between the clumps and the inter-clump medium
is 1E(2-4) . The parameters of the clumps and of the inter-clump medium,
derived from the SFXT flaring behavior, are in good agreement with
macro-clumping scenario and line-driven instability simulations. SFXT are
likely to have larger orbital radius than classical sgHMXB.

712.1933 | Recent progress on the notion of global hyperbolicity | Global hyperbolicity is a central concept in Mathematical Relativity. Here,
we review the different approaches to this concept explaining both, classical
approaches and recent results. The former includes Cauchy hypersurfaces, naked
singularities, and the space of the causal curves connecting two events. The
latter includes structural results on globally hyperbolic spacetimes, their
embeddability in Lorentz-Minkowski, and the recently revised notions of both,
causal and conformal boundaries. Moreover, two criteria for checking global
hyperbolicity are reviewed. The first one applies to general splitting
spacetimes. The second one characterizes accurately global hyperbolicity and

712.1934 | Facilitated spin models: recent and new results | Facilitated or kinetically constrained spin models (KCSM) are a class of
interacting particle systems reversible w.r.t. to a simple product measure.
Each dynamical variable (spin) is re-sampled from its equilibrium distribution
only if the surrounding configuration fulfills a simple local constraint which
\emph{does not involve} the chosen variable itself. Such simple models are
quite popular in the glass community since they display some of the peculiar
features of glassy dynamics, in particular they can undergo a dynamical arrest
reminiscent of the liquid/glass transitiom. Due to the fact that the jumps
rates of the Markov process can be zero, the whole analysis of the long time
behavior becomes quite delicate and, until recently, KCSM have escaped a
rigorous analysis with the notable exception of the East model. In these notes
we will mainly review several recent mathematical results which, besides being
applicable to a wide class of KCSM, have contributed to settle some debated
questions arising in numerical simulations made by physicists. We will also
provide some interesting new extensions. In particular we will show how to deal
with interacting models reversible w.r.t. to a high temperature Gibbs measure
and we will provide a detailed analysis of the so called one spin facilitated
model on a general connected graph.

712.1935 | Eliminating spin contamination in auxiliary-field quantum Monte Carlo:
realistic potential energy curve of F2 | The use of an approximate reference state wave function |Phi_r> in electronic
many-body methods can break the spin symmetry of Born-Oppenheimer
spin-independent Hamiltonians. This can result in significant errors,
especially when bonds are stretched or broken. A simple spin-projection method
is introduced for auxiliary-field quantum Monte Carlo (AFQMC) calculations,
which yields spin-contamination-free results, even with a spin-contaminated
|Phi_r>. The method is applied to the difficult F2 molecule, which is unbound
within unrestricted Hartree-Fock (UHF). With a UHF |Phi_r>, spin contamination
causes large systematic errors and long equilibration times in AFQMC in the
intermediate, bond-breaking region. The spin-projection method eliminates these
problems, and delivers an accurate potential energy curve from equilibrium to
the dissociation limit using the UHF |Phi_r>. Realistic potential energy curves

712.1937 | Model-Independent Bound on the Dark Matter Lifetime | If dark matter (DM) is unstable, in order to be present today, its lifetime
needs to be longer than the age of the Universe, t_U ~ 4 10^{17} s. It is
usually assumed that if DM decays it would do it with some strength through a
radiative mode. In this case, very constraining limits can be obtained from
observations of the diffuse gamma ray background. However, although reasonable,
this is a model-dependent assumption. Here our only assumption is that DM
decays into, at least, one Standard Model (SM) particle. Among these, neutrinos
are the least detectable ones. Hence, if we assume that the only SM decay
daughters are neutrinos, a limit on their flux from DM decays in the Milky Way
sets a conservative, but stringent and model-independent bound on its lifetime.

$\bar{K}N$, $\bar{K}A$ interaction | We evaluate the "$\sigma$" exchange contribution to the $\bar{K}N\to\bar{K}N$
scattering within a chiral unitary approach. We show that the chiral transition
potentials for $\pi \pi \to K \bar{K}$ in the $t$-channel lead to a "$\sigma$"
contribution that vanishes in the $\bar{K}$ forward direction and, hence, would
produce a null "$\sigma$" exchange contribution to the $K^-$ optical potential
in nuclear matter in a simple impulse approximation. This is a consequence of
the fact that the leading order chiral Lagrangian gives an I=0 $\pi\pi\to
K\bar{K}$ amplitude proportional to the squared momentum transfer, $q^2$. This
finding poses questions on the meaning or the origin of "$\sigma$" exchange
potentials used in relativistic mean field approaches to the $K^-$ nuclear
selfenergy. This elementary "$\sigma$" exchange potential in
$\bar{K}N\to\bar{K}N$ is compared to the Weinberg-Tomozawa term and is found to
be smaller than present theoretical uncertainties but will be relevant in the
future when aiming at fitting increasingly more accurate data.

scattering and the properties of the underlying event. The extensive analyses
by Rick Field of data from CDF cannot be reconciled with traditional wisdom
concerning multiple collisions and the AGK cutting rules. Data seem to imply
some kind of color recombination or unexpectedly strong effects from pomeron
vertices. I then discuss theoretical ideas concerning the relation between
multiple collisions and unitarity: the AGK rules, IP loops, dipole cascade
models and diffraction.

712.1943 | Improving population-specific allele frequency estimates by adapting
supplemental data: an empirical Bayes approach | Estimation of the allele frequency at genetic markers is a key ingredient in
biological and biomedical research, such as studies of human genetic variation
or of the genetic etiology of heritable traits. As genetic data becomes
increasingly available, investigators face a dilemma: when should data from
other studies and population subgroups be pooled with the primary data? Pooling
additional samples will generally reduce the variance of the frequency
estimates; however, used inappropriately, pooled estimates can be severely
biased due to population stratification. Because of this potential bias, most
investigators avoid pooling, even for samples with the same ethnic background
and residing on the same continent. Here, we propose an empirical Bayes
approach for estimating allele frequencies of single nucleotide polymorphisms.
This procedure adaptively incorporates genotypes from related samples, so that
more similar samples have a greater influence on the estimates. In every
example we have considered, our estimator achieves a mean squared error (MSE)
that is smaller than either pooling or not, and sometimes substantially
improves over both extremes. The bias introduced is small, as is shown by a
simulation study that is carefully matched to a real data example. Our method
is particularly useful when small groups of individuals are genotyped at a
large number of markers, a situation we are likely to encounter in a
genome-wide association study.

712.1944 | The Simulation of High Pressure Nucleation Experiments in Diffusion
Cloud Chamber | For high- pressure nucleation experiments in upward diffusion cloud chamber,
there is the great deviation of predictions of classical nucleation theory from
experimental results; the discrepancy is more than 10 orders of magnitude of
nucleation rate. Experimental data for 1-propanol vapor are under investigation
in this paper. It was shown that mathematical model of a single droplet growth
and motion semi- quantitatively explained all experimentally discovered
regularities. For explanations low nucleation rate versus high supersaturation,
the coalescence mechanism in gaseous phase has been proposed. As result of
coalescence the vast majority of newly formed clusters evaporate and restore
vapor density and temperature profile in DCC. The observed picture with low
nucleation rate is result of diffusion interaction between small clusters and
droplets in nucleation zone for high- pressure nucleation experiments.

712.1945 | Correlations between political party size and voter memory: A
statistical analysis of opinion polls | This paper describes the application of statistical methods to political
polling data in order to look for correlations and memory effects. We propose
measures for quantifying the political memory using the correlation function
and scaling analysis. These methods reveal time correlations and self-affine
scaling properties respectively, and they have been applied to polling data
from Norway. Power-law dependencies have been found between correlation

the framework of the generalized parton distributions (GPDs) with some simple

experimental data of the form factors, obtained by the Rosenbluth and
polarization transfer, can be described by changing only the slope of the GPDs

712.1948 | Constraining Walking and Custodial Technicolor | We show how to constrain the physical spectrum of walking technicolor models
via precision measurements and modified Weinberg sum rules. We also study
models possessing a custodial symmetry for the S parameter at the effective
Lagrangian level - custodial technicolor - and argue that these models cannot
emerge from walking type dynamics. We suggest that it is possible to have a
very light spin-one axial vector boson. However, in the walking dynamics the

712.1949 | Special Relativistic Simulations of Magnetically-dominated Jets in
Collapsing Massive Stars | We perform a series of two-dimensional magnetohydrodynamic core-collapse
simulations of rapidly rotating and strongly magnetized massive stars. To study
the properties of magnetic explosions for a longer time stretch of postbounce
evolution, we develop a new code under the framework of special relativity
including a realistic equation of state with a multiflavor neutrino leakage
scheme. Our results show the generation of the magnetically-dominated jets in
the two ways. One is launched just after the core-bounce in a prompt way and
another is launched at $ \sim 100 $ ms after the stall of the prompt shock. We
find that the shock-revival occurs when the magnetic pressure becomes strong,
due to the field wrapping, enough to overwhelm the ram pressure of the
accreting matter. The critical toroidal magnetic fields for the magnetic
shock-revival are found to be universal of $\sim 10^{15}\mathrm{G}$ behind the
jets. We point out that the time difference before the shock-revival has a
strong correlation with the explosions energies. Our results suggest that the
magnetically dominated jets are accompanied by the formation of the magnetars.
Since the jets are mildly relativistic, we speculate that they might be the
origin of some observed X-ray flashes.

712.1952 | LERW as an example of off-critical SLEs | Two dimensional loop erased random walk (LERW) is a random curve, whose
continuum limit is known to be a Schramm-Loewner evolution (SLE) with parameter
kappa=2. In this article we study ``off-critical loop erased random walks'',
loop erasures of random walks penalized by their number of steps. On one hand
we are able to identify counterparts for some LERW observables in terms of
symplectic fermions (c=-2), thus making further steps towards a field theoretic
description of LERWs. On the other hand, we show that it is possible to
understand the Loewner driving function of the continuum limit of off-critical
LERWs, thus providing an example of application of SLE-like techniques to
models near their critical point. Such a description is bound to be quite
complicated because outside the critical point one has a finite correlation
length and therefore no conformal invariance. However, the example here shows
the question need not be intractable. We will present the results with emphasis
on general features that can be expected to be true in other off-critical
models.

is a combination of HQET, SCET, and a covariant modification of NRQCD. In the
leading logarithm approximation the effective theory decay amplitude factorizes
into the product of matrix elements of heavy-to-heavy and heavy-to-light
currents. We discuss a possibility of factorization beyond the leading
logarithm approximation and find it doubtful. The Wilson coefficients of the
effective theory electro-weak (EWET) Lagrangian in the next-to-the leading
logarithm approximation are calculated at the matching scale of the decay. The
differential decay rate for the inclusive decay B -> J/\psi+h in the effective
theory framework is evaluated.

712.1955 | Electric field effect on electron spin splitting in SiGe/Si quantum
wells | Effect of electric field on spin splitting in SiGe quantum wells (QWs) has
been studied theoretically. Microscopical calculations of valley and spin
splittings are performed in the effective $sp^3d^5s^*$ tight-binding model. The
splittings oscillate as a function of the QW width due to inter-valley
reflection of the electron wave off the interfaces. In accordance with the
symmetry considerations additional electric-field-induced terms appear in the
electron spin-dependent Hamiltonian. The oscillations of splitting are
suppressed in rather low electric fields. The tight-binding calculations have
been analyzed by using the envelope function approach extended to asymmetrical
QWs.

712.1956 | Discovery of The New WZ Sge Star, SDSS J080434.20+510349.2 | We present the results of photometric observations of SDSS
J080434.20+510349.2 in its low state and during an outburst and spectroscopy
during the outburst. We found such peculiarities as a long-term outburst with
amplitude probably not less than 6m, rarity of the outbursts, eleven
rebrightenings, and a short (0.059713(7) d) superhump period. We conclude that
this star belongs to the WZ Sge-type subclass of cataclysmic variables. The
spectrum shows both emission and absorption lines of H and He superimposed on
the blue continuum. We also found 8 -- 9 min. brightness variations during the

712.1957 | Brauer-Manin obstruction for integral points of homogeneous spaces and
representation by integral quadratic forms | An integer may be represented by a quadratic form over each ring of p-adic
integers and over the reals without being represented by this quadratic form
over the integers. More generally, such failure of a local-global principle may
occur for the representation of one integral quadratic form by another integral
quadratic form. We show that many such examples may be accounted for by a
Brauer-Manin obstruction for the existence of integral points on schemes
defined over the integers. For several types of homogeneous spaces of linear
algebraic groups, this obstruction is shown to be the only obstruction to the
existence of integral points.

712.1958 | Velocity Fields in the Solar Photosphere | Large-scale velocity fields in the solar photosphere remain a mystery in
spite of many years of intensive studies. In this thesis, the new method of the
measurements of the solar photospheric flow fields is proposed. It is based on
local correlation tracking algorithm applied to full-disc dopplergrams obtained
by Michelson Doppler Images (MDI) on-board the Solar and Heliospheric
Observatory (SoHO). The method is tuned and tested on synthetic data, it is
shown that the method is capable of measuring of horizontal velocity fields
with an accuracy of 15 \mps. It is also shown that the method provides the
measurements comparable with time-distance local helioseismology. The method is
applied to real data sets. It reproduces well known properties of solar
photospheric velocity fields. Moreover, the case studies show an evidence about
the influence of the changes in the flow field topology on the stability of the
eruptive filament and support the theory of the dynamical disconnection of
bipolar sunspots from their magnetic roots. The method has a great perspective
in the future use. The meridional flux transportation speed is also studied and
it is shown that the direct measurement may differ from time-distance local
helioseimology in the areas occupied by the strong magnetic field. This result
has an impact to the flux transport dynamo models, which use the meridional
speed as the essential observational input parameter.

712.1959 | Delaunay Edge Flips in Dense Surface Triangulations | Delaunay flip is an elegant, simple tool to convert a triangulation of a
point set to its Delaunay triangulation. The technique has been researched
extensively for full dimensional triangulations of point sets. However, an
important case of triangulations which are not full dimensional is surface
triangulations in three dimensions. In this paper we address the question of
converting a surface triangulation to a subcomplex of the Delaunay
triangulation with edge flips. We show that the surface triangulations which
closely approximate a smooth surface with uniform density can be transformed to
a Delaunay triangulation with a simple edge flip algorithm. The condition on
uniformity becomes less stringent with increasing density of the triangulation.
If the condition is dropped completely, the flip algorithm still terminates
although the output surface triangulation becomes "almost Delaunay" instead of
exactly Delaunay.

712.1961 | Dirichlet branes and a cohomological definition of time flow | Dirichlet branes are objects whose transverse coordinates in space are
matrix-valued functions. This leads to considering a matrix algebra or, more
generally, a Lie algebra, as the classical phase space of a certain dynamics
where the multiplication of coordinates, being given by matrix multiplication,
is nonabelian. Further quantising this dynamics by means of a star-product
introduces noncommutativity (besides nonabelianity) as a quantum h-deformation.
The algebra of functions on a standard Poisson manifold is replaced with the
universal enveloping algebra of the given Lie algebra. We define generalised
Poisson brackets on this universal enveloping algebra, examine their
properties, and conclude that they provide a natural framework for dynamical

712.1962 | The BARISTA: A model for bid arrivals in online auctions | The arrival process of bidders and bids in online auctions is important for
studying and modeling supply and demand in the online marketplace. A popular
assumption in the online auction literature is that a Poisson bidder arrival
process is a reasonable approximation. This approximation underlies theoretical
derivations, statistical models and simulations used in field studies. However,
when it comes to the bid arrivals, empirical research has shown that the
process is far from Poisson, with early bidding and last-moment bids taking
place. An additional feature that has been reported by various authors is an
apparent self-similarity in the bid arrival process. Despite the wide evidence
for the changing bidding intensities and the self-similarity, there has been no
rigorous attempt at developing a model that adequately approximates bid
arrivals and accounts for these features. The goal of this paper is to
introduce a family of distributions that well-approximate the bid time
distribution in hard-close auctions. We call this the BARISTA process (Bid
ARrivals In STAges) because of its ability to generate different intensities at
different stages. We describe the properties of this model, show how to
simulate bid arrivals from it, and how to use it for estimation and inference.
We illustrate its power and usefulness by fitting simulated and real data from
eBay.com. Finally, we show how a Poisson bidder arrival process relates to a
BARISTA bid arrival process.

712.1963 | The role of the Weibel instability at the reconnection jet front in
relativistic pair plasma reconnection | The role of the Weibel instability is investigated for the first time in the
context of the large-scale magnetic reconnection problem. A late-time evolution
of magnetic reconnection in relativistic pair plasmas is demonstrated by
particle-in-cell (PIC) simulations. In the outflow regions, powerful
reconnection jet piles up the magnetic fields and then a tangential
discontinuity appears there. Further downstream, it is found that the
two-dimensional extension of the relativistic Weibel instability generates
electro-magnetic fields, which are comparable to the anti-parallel or piled-up
fields. In a microscopic viewpoint, the instability allows plasma's multiple
interactions with the discontinuity. In a macroscopic viewpoint, the
instability leads to rapid expansion of the current sheet and then the

712.1964 | The Fast Read-out System for the MAPMTs of COMPASS RICH-1 | A fast readout system for the upgrade of the COMPASS RICH detector has been
developed and successfully used for data taking in 2006 and 2007. The new
readout system for the multi-anode PMTs in the central part of the photon
detector of the RICH is based on the high-sensitivity MAD4
preamplifier-discriminator and the dead-time free F1-TDC chip characterized by
high-resolution. The readout electronics has been designed taking into account
the high photon flux in the central part of the detector and the requirement to
run at high trigger rates of up to 100 kHz with negligible dead-time. The
system is designed as a very compact setup and is mounted directly behind the
multi-anode photomultipliers. The data are digitized on the frontend boards and
transferred via optical links to the readout system. The read-out electronics
system is described in detail together with its measured performances.

712.1965 | Oscillator-Morse-Coulomb mappings and algebras for constant or
position-dependent mass | The bound-state solutions and the su(1,1) description of the $d$-dimensional
radial harmonic oscillator, the Morse and the $D$-dimensional radial Coulomb
Schr\"odinger equations are reviewed in a unified way using the point canonical
transformation method. It is established that the spectrum generating su(1,1)
algebra for the first problem is converted into a potential algebra for the
remaining two. This analysis is then extended to Schr\"odinger equations
containing some position-dependent mass. The deformed su(1,1) construction
recently achieved for a $d$-dimensional radial harmonic oscillator is easily
extended to the Morse and Coulomb potentials. In the last two cases, the
equivalence between the resulting deformed su(1,1) potential algebra approach
and a previous deformed shape invariance one generalizes to a

effective mass M^*(T,x), describing all diverse experimental facts in 2D 3He in
unified manner and demonstrating that the universal behavior of M^*(T,x)

explicit Delta-resonance degrees of freedom. We show that up to
next-to-next-to-leading order, the only contribution to the isospin symmetric
three-nucleon force involving the spin-3/2 degrees of freedom is given by the
two-pion-exchange diagram with an intermediate delta, frequently called the
Fujita-Miyazawa force. We also analyze the leading isospin-breaking corrections
due to the delta. For that, we give the first analysis of the delta quartet
mass splittings in chiral effective field theory. The charge-symmetry breaking
three-nucleon force due to an intermediate delta excitation is small, of the
order of a few keV.

712.197 | Morphogenesis of growing soft tissues | Recently, much attention has been given to a noteworthy property of some soft
tissues: their ability to grow. Many attempts have been made to model this
behaviour in biology, chemistry and physics. Using the theory of finite
elasticity, Rodriguez has postulated a multiplicative decomposition of the
geometric deformation gradient into a growth-induced part and an elastic one
needed to ensure compatibility of the body. In order to fully explore the
consequences of this hypothesis, the equations describing thin elastic objects
under finite growth are derived. Under appropriate scaling assumptions for the
growth rates, the proposed model is of the Foppl-von Karman type. As an
illustration, the circumferential growth of a free hyperelastic disk is
studied.

712.1971 | Quadratic algebras and position-dependent mass Schr\"odinger equations | During recent years, exact solutions of position-dependent mass Schr\"odinger
equations have inspired intense research activities, based on the use of point
canonical transformations, Lie algebraic methods or supersymmetric quantum
mechanical techniques. Here we highlight the interest of another approach to
such problems, relying on quadratic algebras. We illustrate this point by
constructing spectrum generating algebras for a class of $d$-dimensional radial
harmonic oscillators with $d\ge2$ (including the one-dimensional oscillator on
the line via some minor changes) and a specific mass choice. This provides us

712.1973 | Conformational equilibria in monomeric alpha-synuclein at the single
molecule level | Natively unstructured proteins defy the classical "one sequence-one
structure" paradigm of protein science. Monomers of these proteins in
pathological conditions can aggregate in the cell, a process that underlies
socially relevant neurodegenerative diseases such as Alzheimer and Parkinson. A
full comprehension of the formation and structure of the so-called misfolded
intermediates from which the aggregated states ensue is still lacking. We
characterized the folding and the conformational diversity of alpha-synuclein
(aSyn), a natively unstructured protein involved in Parkinson disease, by
mechanically stretching single molecules of this protein and recording their
mechanical properties. These experiments permitted us to directly observe
directly and quantify three main classes of conformations that, under in vitro
physiological conditions, exist simultaneously in the aSyn sample, including
disordered and "beta-like" structures. We found that this class of "beta-like"
structures is directly related to aSyn aggregation. In fact, their relative
abundance increases drastically in three different conditions known to promote
the formation of aSyn fibrils: the presence of Cu2+, the occurrence of the
pathogenic A30P mutation, and high ionic strength. We expect that a critical
concentration of aSyn with a "beta-like" structure must be reached to trigger
fibril formation. This critical concentration is therefore controlled by a
chemical equilibrium. Novel pharmacological strategies can now be tailored to
act upstream, before the aggregation process ensues, by targeting this
equilibrium. To this end, Single Molecule Force Spectroscopy can be an
effective tool to tailor and test new pharmacological agents.

712.1974 | On the calculation of the Casimir forces | Casimir forces are a manifestation of the change in the zero-point energy of
the vacuum caused by the insertion of boundaries. We show how the Casimir force
can be computed by consideration of the vacuum fluctuations that are suppressed
by the boundaries, and rederive the scalar Casimir effects for a series of
geometries. For the planar case a finite universal force is automatically
found. For curved geometries formally divergent expressions are encountered
which we argue are largely due to the divergent self-energy of the boundary
contributing to the force. This idea is supported by computing the effect for a
fixed perimeter wedge-arc geometry in two dimensions.

712.1975 | Reentrant spin glass transition in LuFe2O4 | We have carried out a comprehensive investigation of magnetic properties of
LuFe$_2$O$_4$, using AC susceptibility, DC magnetization and specific heat. A
magnetic phase transition around $\sim$236 K was observed with DC magnetization
and specific heat measurements, which is identified as a paramagnetic to
ferrimagnetic transition based on the nonlinear susceptibility data. Upon
further cooling below this temperature, we also observed highly relaxational
magnetic behavior: the DC magnetization exhibits history and time dependence,
and the real and imaginary part of the AC susceptibility shows large frequency
dependence. Dynamic scaling of the AC susceptibility data suggests that this
low temperature phase can be described as a reentrant spin glass phase. We also
discuss magnetic field dependence of the spin glass transition and aging,
memory and rejuvenation effect below the glass transition temperature around
228 K.

712.1976 | Scaling of entanglement support for Matrix Product States | The power of matrix product states to describe infinite-size
translational-invariant critical spin chains is investigated. At criticality,
the accuracy with which they describe ground state properties of a system is
limited by the size $\chi$ of the matrices that form the approximation. This
limitation is quantified in terms of the scaling of the half-chain entanglement
entropy. In the case of the quantum Ising model, we find $S \sim {1/6}\log
\chi$ with high precision. This result can be understood as the emergence of an
effective finite correlation length $\xi_\chi$ ruling of all the scaling
properties in the system. We produce five extra pieces of evidence for this
finite-$\chi$ scaling, namely, the scaling of the correlation length, the
scaling of magnetization, the shift of the critical point, and the scaling of
the entanglement entropy for a finite block of spins. All our computations are
consistent with a scaling relation of the form $\xi_\chi\sim \chi^{\kappa}$,
with $\kappa=2$ for the Ising model. In the case of the Heisenberg model, we
find similar results with the value $\kappa\sim 1.37$. We also show how
finite-$\chi$ scaling allow to extract critical exponents. These results are
obtained using the infinite time evolved block decimation algorithm which works
in the thermodynamical limit and are verified to agree with density matrix
renormalization group results.

712.1977 | A magnetized completion of the $\Lambda$CDM paradigm | The standard $\Lambda$CDM paradigm is complemented with a magnetized
contribution whose effects on the anisotropies of the Cosmic Microwave
Background (CMB) are assessed by means of a dedicated numerical approach. The
accuracy on the temperature and polarization correlations stems from the
inclusion of the large-scale magnetic fields both at the level of the initial
conditions and at the level of the Einstein-Boltzmann hierarchy which is
consistently embedded in a generalized magnetohydrodynamical framework.
Examples of the calculations of the temperature and polarization angular power
spectra are illustrated and discussed. The reported results and the described
numerical tools set the ground for a consistent inclusion of a magnetized
contribution in current strategies of cosmological parameter estimation.
