712.0479 | First quintuplet frequency solution of a Blazhko variable: light curve
analysis of RV UMa | RV UMa is one of the RRab stars showing regular large amplitude light curve
modulation. Extended photoelectric observations of RV UMa obtained at the
Konkoly Observatory were published by Kanyo (1976). The analysis of the data
was published by Kovacs (1995). After detecting an error in the reduction
procedure of the published Konkoly data, corrected photometric data are
presented with additional, previously unpublished measurements.
The reanalysis of the combination of the corrected Konkoly data supplemented
with Preston & Spinrad's (1967) observations has led to the discovery that the
adequate mathematical model of the light curve is, in fact, a quintuplet,
instead of a triplet frequency solution. This finding has crucial importance in
the interpretation of the Blazhko phenomenon, as triplet (doublet) is the
preferred structure in the resonance models, quintuplet in the magnetic models.
Period changes of both the pulsation and the modulation light variations of
RV UMa have been detected based on its century long photometric observations.
An overall anticorrelation between the pulsation and the modulation period
changes can be defined with dP_{Bl} / dP_0 = -8.6 pm 10^4 gradient, i.e., the
modulation period is longer if the pulsation period is shorter. Between 1946
and 1975 the pulsation and modulation periods showed, however, parallel
changes, which points to that there is no strict relation between the changes
in the periods of the pulsation and the modulation.

712.0481 | Charmed-Meson Fragmentation Functions with Finite-Mass Corrections | We elaborate the inclusive production of single heavy-flavored hadrons in
e^+e^- annihilation at next-to-leading order in the general-mass
variable-flavor-number scheme. In this framework, we determine non-perturbative
fragmentation functions for D^0, D^+, and D^{*+} mesons by fitting experimental
data from the Belle, CLEO, ALEPH, and OPAL Collaborations, taking dominant
electroweak corrections due to photonic initial-state radiation into account.
We assess the significance of finite-mass effects through comparisons with a
similar analysis in the zero-mass variable-flavor-number scheme. Under Belle
and CLEO experimental conditions, charmed-hadron mass effects on the phase

712.0482 | Abundance variations and first ionization potential trends during large
stellar flares | The Solar First Ionization Potential (FIP) effect, where low-FIP elements are
enriched in the corona relative to the photosphere, while high-FIP abundances
remain unchanged, has been known for a long while. High resolution X-ray
spectroscopy has revealed that active stellar coronae show an opposite effect,
which was labeled the Inverse-FIP (IFIP) effect. The correlation found between
coronal activity and the FIP/IFIP bias suggested perhaps that flaring activity
is involved in switching from FIP to IFIP. This work aims at a more systematic
understanding of the FIP trends during stellar flares and complements an
earlier study based on Chandra alone. The eight brightest X-ray flares observed
with XMM-Newton are analyzed and compared with their respective quiescence
states. Together with six previous flares observed with Chandra, this
establishes the best currently available sample of flares. We look for
abundance variations during the flare and their correlation with FIP. For that
purpose, we define a new FIP bias measure. A trend is found where coronae that
are IFIP biased in quiescence, during flares show a FIP bias with respect to
their quiescence composition. This effect is reversed for coronae that are FIP
biased in quiescence. The observed trend is thus consistent with chromospheric
evaporation rather than with a FIP mechanism operating during flares. It also
suggests that the quiescent IFIP bias is real and that the large flares are not
the direct cause of the IFIP effect in stellar coronae.

712.0483 | Computational Complexity of interacting electrons and fundamental
limitations of Density Functional Theory | One of the central problems in quantum mechanics is to determine the ground
state properties of a system of electrons interacting via the Coulomb
potential. Since its introduction by Hohenberg, Kohn, and Sham, Density
Functional Theory (DFT) has become the most widely used and successful method
for simulating systems of interacting electrons, making their original work one
of the most cited in physics. In this letter, we show that the field of
computational complexity imposes fundamental limitations on DFT, as an
efficient description of the associated universal functional would allow to
solve any problem in the class QMA (the quantum version of NP) and thus
particularly any problem in NP in polynomial time. This follows from the fact
that finding the ground state energy of the Hubbard model in an external
magnetic field is a hard problem even for a quantum computer, while given the
universal functional it can be computed efficiently using DFT. This provides a
clear illustration how the field of quantum computing is useful even if quantum
computers would never be built.
| quant-ph | one of the central problems in quantum mechanics is to determine the ground state properties of a system of electrons interacting via the coulomb potential since its introduction by hohenberg kohn and sham density functional theory dft has become the most widely used and successful method for simulating systems of interacting electrons making their original work one of the most cited in physics in this letter we show that the field of computational complexity imposes fundamental limitations on dft as an efficient description of the associated universal functional would allow to solve any problem in the class qma the quantum version of np and thus particularly any problem in np in polynomial time this follows from the fact that finding the ground state energy of the hubbard model in an external magnetic field is a hard problem even for a quantum computer while given the universal functional it can be computed efficiently using dft this provides a clear illustration how the field of quantum computing is useful even if quantum computers would never be built | [['one', 'of', 'the', 'central', 'problems', 'in', 'quantum', 'mechanics', 'is', 'to', 'determine', 'the', 'ground', 'state', 'properties', 'of', 'a', 'system', 'of', 'electrons', 'interacting', 'via', 'the', 'coulomb', 'potential', 'since', 'its', 'introduction', 'by', 'hohenberg', 'kohn', 'and', 'sham', 'density', 'functional', 'theory', 'dft', 'has', 'become', 'the', 'most', 'widely', 'used', 'and', 'successful', 'method', 'for', 'simulating', 'systems', 'of', 'interacting', 'electrons', 'making', 'their', 'original', 'work', 'one', 'of', 'the', 'most', 'cited', 'in', 'physics', 'in', 'this', 'letter', 'we', 'show', 'that', 'the', 'field', 'of', 'computational', 'complexity', 'imposes', 'fundamental', 'limitations', 'on', 'dft', 'as', 'an', 'efficient', 'description', 'of', 'the', 'associated', 'universal', 'functional', 'would', 'allow', 'to', 'solve', 'any', 'problem', 'in', 'the', 'class', 'qma', 'the', 'quantum', 'version', 'of', 'np', 'and', 'thus', 'particularly', 'any', 'problem', 'in', 'np', 'in', 'polynomial', 'time', 'this', 'follows', 'from', 'the', 'fact', 'that', 'finding', 'the', 'ground', 'state', 'energy', 'of', 'the', 'hubbard', 'model', 'in', 'an', 'external', 'magnetic', 'field', 'is', 'a', 'hard', 'problem', 'even', 'for', 'a', 'quantum', 'computer', 'while', 'given', 'the', 'universal', 'functional', 'it', 'can', 'be', 'computed', 'efficiently', 'using', 'dft', 'this', 'provides', 'a', 'clear', 'illustration', 'how', 'the', 'field', 'of', 'quantum', 'computing', 'is', 'useful', 'even', 'if', 'quantum', 'computers', 'would', 'never', 'be', 'built']] | [-0.09807372761358107, 0.1037145218500934, -0.11862571172682303, 0.10868020956138415, -0.04570545918175152, -0.1584425945021212, 0.033264763592742386, 0.31166772222844885, -0.28945859646408023, -0.31697820805811455, 0.05838846375300948, -0.23831467557432395, -0.15863675892353057, 0.220780267022284, -0.025572148758385864, 0.07858405725331977, 0.050624835858387604, 0.06700429884450776, -0.05683966873080603, -0.24730527178517409, 0.27827933564017127, 0.05653713078836777, 0.2440828303793179, 0.07862390931163515, 0.04544356767088175, 0.04846984730235168, 0.053122558620359216, 0.04506810966546514, -0.07239508826992408, 0.14408865573217294, 0.2842053642456553, 0.10300468850082585, 0.30270632711106116, -0.48284314669668676, -0.21390787564218045, 0.10433670394255647, 0.13258162473993643, 0.15910377566303527, -0.06077015878699188, -0.2459320159469332, 0.07128034248415913, -0.16242435946395353, -0.14058952628235732, -0.07688609145315631, 0.012868009805014092, -0.039635119465113215, -0.20260315737287912, 0.07701100445751632, 0.04319404109214832, 0.02305586318884577, -0.05289816336855958, -0.0868215175498543, 0.045105183369347025, 0.11067722237535886, 0.0007028294946732265, 0.0669333427226437, 0.121904592958412, -0.1777273749041238, -0.1348941251648856, 0.42197615112577164, -0.013062424274726904, -0.1799391012479152, 0.20162031804876668, -0.08845019605476409, -0.1631369465017425, 0.09382505374894078, 0.10229888693828668, 0.09866294392251543, -0.15649112568369933, 0.1802217765914143, -0.027146008877482797, 0.19244895062675432, 0.0048818457073399, 0.035907656887014, 0.1983038220767464, 0.140702466126864, 0.06305615488173706, 0.13341659765424474, -0.04867008849479524, -0.13086578732622522, -0.2604184424664293, -0.19976461740343698, -0.2534397202796702, 0.07181920575111041, -0.03489269219047855, -0.1982740746411894, 0.3958876876049076, 0.1681315124680155, 0.1220974707962679, 0.0007797864891056504, 0.27659596900854794, 0.16909162097144873, 0.04169908382497462, 0.07626706001082702, 0.2370138797004308, 0.1551068141856896, 0.0734797596439187, -0.23022564291554903, 0.05890272549220494, 0.06058199669700116] |
712.0484 | On the Analysis of Intermediate-Energy Coulomb Excitation Experiments | In a recent publication (Bertulani et al., PLB 650 (2007) 233 and
arXiv:0704.0060v2) the validity of analysis methods used for
intermediate-energy Coulomb excitation experiments was called into question.
Applying a refined theory large corrections of results in the literature seemed
needed. We show that this is not the case and that the large deviations
observed are due to the use of the wrong experimental parameters. We
furthermore show that an approximate expression derived by Bertulani et al. is
in fact equivalent to the theory of Winther and Alder (NPA 319 (1979) 518), an
analysis method often used in the literature.

712.0485 | Operation of a Thick Gas Electron Multiplier (THGEM) in Ar, Xe and Ar-Xe | We present the results of our recent studies of a Thick Gaseous Electron
Multiplier (THGEM)-based detector, operated in Ar, Xe and Ar:Xe (95:5) at
various gas pressures. Avalanche-multiplication properties and energy
resolution were investigated with soft x-rays for different detector
configurations and parameters. Gains above 10E4 were reached in a double-THGEM
detector, at atmospheric pressure, in all gases, in almost all the tested
conditions; in Ar:Xe (95:5) similar gains were reached at pressures up to 2
bar. The energy resolution dependence on the gas, pressure, hole geometry and

712.0488 | Indirect control with quantum accessor: coherent control by initial
state preparation | This is the second one in our series of papers on indirect quantum control
assisted by quantum accessor. In this paper we propose and study a new class of
indirect quantum control(IDQC) scheme based on the initial states preparation
of the accessor. In the present scheme, after the initial state of the accessor
is properly prepared, the system is controlled by repeatedly switching on and
off the interaction between the system and the accessor. This is different from
the protocol of our first paper, where we manipulate the interaction between
the controlled system and the accessor. We prove the controllability of the
controlled system for the proposed indirect control scheme. Furthermore, we

712.0489 | Glauber dynamics on nonamenable graphs: Boundary conditions and mixing
time | We study the stochastic Ising model on finite graphs with n vertices and
bounded degree and analyze the effect of boundary conditions on the mixing
time. We show that for all low enough temperatures, the spectral gap of the
dynamics with (+)-boundary condition on a class of nonamenable graphs, is
strictly positive uniformly in n. This implies that the mixing time grows at
most linearly in n. The class of graphs we consider includes hyperbolic graphs
with sufficiently high degree, where the best upper bound on the mixing time of
the free boundary dynamics is polynomial in n, with exponent growing with the
inverse temperature. In addition, we construct a graph in this class, for which
the mixing time in the free boundary case is exponentially large in n. This
provides a first example where the mixing time jumps from exponential to linear
in n while passing from free to (+)-boundary condition. These results extend
the analysis of Martinelli, Sinclair and Weitz to a wider class of nonamenable
graphs.

712.0492 | Integral means and boundary limits of Dirichlet series | We study the boundary behavior of functions in the Hardy spaces HD^p for
ordinary Dirichlet series. Our main result, answering a question of H.
Hedenmalm, shows that the classical F. Carlson theorem on integral means does
not extend to the imaginary axis for functions in HD^\infty, i.e., for ordinary
Dirichlet series in H^\infty of the right half-plane. We discuss an important
embedding problem for HD^p, the solution of which is only known when p is an
even integer. Viewing HD^p as Hardy spaces of the infinite-dimensional
polydisc, we also present analogues of Fatou's theorem.

712.0496 | Near-infrared evolution of brightest cluster galaxies in the most X-ray
luminous clusters since z=1 | We investigate the near infrared evolution of brightest cluster galaxies
(BCGs) from a sample of rich galaxy clusters since z=1. By employing an X-ray
selection of Lx>1e44 erg s-1 we limit environmental effects by selecting BCGs
in comparably high density regions. We find a positive relationship between
X-ray and near-infrared luminosity for BCGs in clusters with Lx>5e44 erg s-1.
Applying a correction for this relation we reduce the scatter in the BCG
absolute magnitude by a factor of 30%. The near-infrared J-K colour evolution
demonstrates that the stellar population in BCGs has been in place since at
least z=2 and that we expect a shorter period of star formation than that
predicted by current hierarchical merger models. We also confirm that there is

712.0497 | De-contamination of cosmological 21-cm maps | We present a method for extracting the expected cosmological 21-cm signal
from the epoch of reionization, taking into account contaminating radiations
and random instrumental noise. The method is based on the maximum a-posteriori
probability (MAP) formalism and employs the coherence of the contaminating
radiation along the line-of-sight and the three-dimensional correlations of the
cosmological signal. We test the method using a detailed and comprehensive
modeling of the cosmological 21-cm signal and the contaminating radiation. The
signal is obtained using a high resolution N-body simulation where the gas is
assumed to trace the dark matter and is reionized by stellar radiation computed
from semi-analytic galaxy formation recipes. We model contaminations to the
cosmological signal from synchrotron and free-free galactic foregrounds and
extragalactic sources including active galactic nuclei, radio haloes and
relics, synchrotron and free-free emission from star forming galaxies, and
free-free emission from dark matter haloes and the intergalactic medium. We
provide tests of the reconstruction method for several rms values of
instrumental noise from $\sigma_{N}=1$ to 250 mK. For low instrumental noise,
the recovered signal, along individual lines-of-sight, fits the true
cosmological signal with a mean rms difference of $d_{rms}\approx 1.7\pm 0.6$
for $\sigma_{N}=1$ mK, and $d_{rms}\approx 4.2\pm 0.4$ for $\sigma_{N}=5$ mK.
The one-dimensional power spectrum is nicely reconstructed for all values of
$\sigma_{N}$ considered here, while the reconstruction of the two-dimensional
power spectrum and the Minkowski functionals is good only for noise levels of
the order of few mK.

712.0498 | Measurement of the Strong Phase in D0 -> K+pi- Using Quantum
Correlations | We exploit the quantum coherence between pair-produced D0 and D0bar in
psi(3770) decays to study charm mixing and to make a first measurement of the
relative strong phase \delta between D0 -> K+pi- and D0bar -> K+pi-. Using 281
pb^-1 of e+e- collision data collected with the CLEO-c detector at E_cm=3.77
GeV, as well as branching fraction input from other experiments, we make a
preliminary determination of \cos\delta = 1.03 +- 0.19 +- 0.08, where the
uncertainties are statistical and systematic, respectively. By further
including other external mixing parameter measurements, we obtain an alternate

712.0499 | Simrank++: Query rewriting through link analysis of the click graph | We focus on the problem of query rewriting for sponsored search. We base
rewrites on a historical click graph that records the ads that have been
clicked on in response to past user queries. Given a query q, we first consider
Simrank as a way to identify queries similar to q, i.e., queries whose ads a
user may be interested in. We argue that Simrank fails to properly identify
query similarities in our application, and we present two enhanced version of
Simrank: one that exploits weights on click graph edges and another that
exploits ``evidence.'' We experimentally evaluate our new schemes against
Simrank, using actual click graphs and queries form Yahoo!, and using a variety
of metrics. Our results show that the enhanced methods can yield more and
better query rewrites.

712.05 | GRB 070724B: the first Gamma Ray Burst localized by SuperAGILE and its
Swift X-ray Afterglow | GRB 070724B is the first Gamma Ray Burst localized by SuperAGILE, the hard
X-ray monitor aboard the AGILE satellite. The coordinates of the event were
published $\sim 19$ hours after the trigger. The Swift X-Ray Telescope pointed
at the SuperAGILE location and detected the X-ray afterglow inside the
SuperAGILE error circle. The AGILE gamma-ray Tracker and Minicalorimeter did
not detect any significant gamma ray emission associated with GRB 070724B in
the MeV and GeV range, neither prompt nor delayed. Searches of the optical
afterglow were performed by the Swift UVOT and the Palomar automated 60-inch
telescopes without any significant detection. Similarly the Very Large Array
did not detect a radio afterglow. This is the first GRB event with a firm upper

712.0501 | A suggestion for B-10 imaging during boron neutron capture therapy | Selective accumulation of B-10 compound in tumour tissue is a fundamental
condition for the achievement of BNCT (Boron Neutron Capture Therapy), since
the effectiveness of therapy irradiation derives just from neutron capture
reaction of B-10. Hence, the determination of the B-10 concentration ratio,
between tumour and healthy tissue, and a control of this ratio, during the
therapy, are essential to optimise the effectiveness of the BNCT, which it is
known to be based on the selective uptake of B-10 compound. In this work,
experimental methods are proposed and evaluated for the determination in vivo
of B-10 compound in biological samples, in particular based on neutron
radiography and gammaray spectroscopy by telescopic system. Measures and Monte
Carlo calculations have been performed to investigate the possibility of
executing imaging of the 10B distribution, both by radiography with thermal
neutrons, using 6LiF/ZnS:Ag scintillator screen and a CCD camera, and by
spectroscopy, based on the revelation of gamma-ray reaction products from B-10
and the H. A rebuilding algorithm has been implemented. The present study has
been done for the standard case of B-10 uptake, as well as for proposed case in
which, to the same carrier, is also synthesized Gd-157, in the amount of is
used like a contrast agent in NMRI.

712.0502 | Photodetection in silicon beyond the band edge with surface states | Silicon is an extremely attractive material platform for integrated optics at
telecommunications wavelengths, particularly for integration with CMOS
circuits. Developing detectors and electrically pumped lasers at telecom
wavelengths are the two main technological hurdles before silicon can become a
comprehensive platform for integrated optics. We report on the generation of
free carriers in unimplanted SOI ridge waveguides, which we attribute to
surface state absorption. By electrically contacting the waveguides, a
photodetector with a responsivity of 36 mA/W and quantum efficiency of 2.8% is

712.0503 | Flavor Changing Neutral Higgs Bosons in a Supersymmetric Extension based
on a $Q_6$ Family Symmetry | A supersymmetric extension of the standard model based on the discrete $Q_6$
family symmetry is considered, and we investigate flavor-changing neutral
current (FCNC) processes, especially those mediated by heavy flavor-changing
neutral Higgs bosons. Because of the family symmetry the number of the
independent Yukawa couplings is smaller than that of the observed quantities
such as the Cabibbo-Kobayashi-Maskawa matrix and the quark masses, so that the
FCNCs can be parametrized only by the mixing angles and masses of the Higgs
fields. We focus our attention on the mass differences of the neutral $K, D$
and $B$ mesons. All the constraints including that from the ratio $\Delta
M_{B_s}/\Delta M_{B_d}$ can be satisfied, if the heavy Higgs bosons are heavier
than $\sim 1.5$ TeV. If the constraint from $\Delta M_K$ is slightly relaxed,
the heavy Higgs bosons can be as light as $\sim 0.4$ TeV, which is within the
accessible range of LHC.

712.0504 | Microscopic Mechanism and Pairing Symmetry of Superconductivity in the
Noncentrosymmetric Heavy Fermion Systems CeRhSI$_3$ and CeIrSi$_3$ | We study the pairing symmetry of the noncentrosymmetric heavy fermion
superconductors CeRhSi$_3$ and CeIrSi$_3$ under pressures, which are both
antiferromagnets at ambient pressure. We solve the Eliashberg equation by means
of the random phase approximation and find that the mixed state of extended
s-wave and p-wave rather than the $d+f$ wave state could be realized by
enhanced antiferromagnetic spin fluctuations. It is elucidated that the gap
function has line nodes on the Fermi surface and the resulting density of state
in the superconducting state shows a similar character to that of usual d-wave

712.0505 | Photonic portal to the sterile world of cold dark matter | We assume that the cold dark matter consists of spin-1/2 and spin-0 particles
described by a bispinor field \psi and a scalar field \phi, sterile from all
Standard Model charges (in contrast, neutralinos, supersymmetric candidates for
cold dark matter, are not sterile from weak Standard Model charges). We
propose, however, that such a sterile world can contact with our Standard Model
world not only through gravity but also through a portal provided by photons
coupled to sterile particles by means of two very weak effective interactions
-(f/M^2)\phi F^{\mu\nu}\phi F_{\mu\nu} and -(f'/M^2) (\bar\psi \sigma^{\mu\nu}
\psi)\phi F_{\mu\nu}, where M is a very large mass scale and f and f' are
dimensionless coupling constants. Thus, in our picture, the electromagnetic
field F_{\mu\nu} - as the only Standard Model field - participates in both
worlds, providing a nongravitational link between them (other than the popular
supersymmetric weak interaction, active in the case of neutralinos). In
consequence, there appears a tiny quasi-magnetic correction to the conventional
electromagnetic current (described in Appendix A).

712.0509 | Universal behavior of baryons and mesons transverse momentum
distributions in the framework of percolation of strings | In the framework of percolation of strings, the transverse momentum
distributions in AA and hh collisions at all centralities and energies follow a
universal behavior. The width of these distributions is related to the width of
the distribution of the size of the clusters formed from the overlapping of the
produced strings. The difference between the distributions for baryons and
mesons originates in the fragmentation of clusters of several strings which
enhance the particles with higher number of constituents. The results agree
with SPS and RHIC data. The predictions for LHC show differences for baryons

712.051 | A Three-Dimensional Picture of the Delayed-Detonation Model of Type Ia
Supernovae | Deflagration models poorly explain the observed diversity of SNIa. Current
multidimensional simulations of SNIa predict a significant amount of, so far
unobserved, carbon and oxygen moving at low velocities. It has been proposed
that these drawbacks can be resolved if there is a sudden jump to a detonation
(delayed detonation), but this kind of models has been explored mainly in one
dimension. Here we present new three-dimensional delayed detonation models in
which the deflagraton-to-detonation transition (DDT) takes place in conditions
like those favored by one-dimensional models. We have used a SPH code adapted
to SNIa with algorithms devised to handle subsonic as well as supersonic
combustion fronts. The starting point was a C-O white dwarf of 1.38 solar
masses. When the average density on the flame surface reached 2-3x10^7 g/cm^3 a
detonation was launched. The detonation wave processed more than 0.3 solar
masses of carbon and oxygen, emptying the central regions of the ejecta of
unburned fuel and raising its kinetic energy close to the fiducial 10^51 ergs
expected from a healthy Type Ia supernova. The final amount of 56Ni synthesized
also was in the correct range. However, the mass of carbon and oxygen ejected
is still too high. The three-dimensional delayed detonation models explored
here show an improvement over pure deflagration models, but they still fail to
coincide with basic observational constraints. However, there are many aspects
of the model that are still poorly known (geometry of flame ignition, mechanism
of DDT, properties of detonation waves traversing a mixture of fuel and ashes).
Therefore, it will be worth pursuing its exploration to see if a good SNIa
model based on the three-dimensional delayed detonation scenario can be
obtained.

712.0511 | Accurate Quantitative Spectroscopy of OB Stars: C and N abundances near
the Main Sequence | We present a state-of-the-art analysis technique able to simultaneously
reproduce the entire H and He spectra of OB-type stars in the visual and the
near-IR and to derive highly accurate metal abundances (so far C and N). The
spectrum synthesis relies on a hybrid non-LTE approach involving our most
recent model atoms. Accurate atmospheric parameters, with reduced systematic
errors, are derived spectroscopically (from Stark-broadened H lines and
ionization equilibria of He I/II and C II-IV) for a sample of randomly
distributed stars in the solar vicinity. Highly consistent abundances are found
in contrast to previous reports indicating broad scatter and large
uncertainties. The improvements result from avoidance of systematic errors in

712.0512 | Nested Subgraphs of Complex Networks | We analytically explore the scaling properties of a general class of nested
subgraphs in complex networks, which includes the $K$-core and the
$K$-scaffold, among others. We name such class of subgraphs $K$-nested
subgraphs due to the fact that they generate families of subgraphs such that
$...S_{K+1}({\cal G})\subseteq S_K({\cal G})\subseteq S_{K-1}({\cal G})...$.
Using the so-called {\em configuration model} it is shown that any family of
nested subgraphs over a network with diverging second moment and finite first
moment has infinite elements (i.e. lacking a percolation threshold). Moreover,
for a scale-free network with the above properties, we show that any nested
family of subgraphs is self-similar by looking at the degree distribution. Both
numerical simulations and real data are analyzed and display good agreement
with our theoretical predictions.

712.0515 | Normal Globular Cluster Systems in Massive Low Surface Brightness
Galaxies | We present the results of a study of the globular cluster systems of 6
massive spiral galaxies, originally cataloged as low surface brightness
galaxies but here shown to span a wide range of central surface brightness
values, including two intermediate to low surface brightness galaxies. We used
the Advanced Camera for Surveys on board HST to obtain photometry in the F475W
and F775W bands and select sources with photometric and morphological
properties consistent with those of globular clusters. A total of 206
candidates were identified in our target galaxies. From a direct comparison
with the Galactic globular cluster system we derive specific frequency values
for each galaxy that are in the expected range for late-type galaxies. We show
that the globular cluster candidates in all galaxies have properties consistent
with globular cluster systems of previously studied galaxies in terms of
luminosity, sizes and color. We establish the presence of globular clusters in
the two intermediate to low surface brightness galaxies in our sample and show
that their properties do not have any significant deviation from the behavior
observed in the other sample galaxies. Our results are broadly consistent with
a scenario in which low surface brightness galaxies follow roughly the same
evolutionary history as normal (i.e. high surface) brightness galaxies except
at a much lower rate, but require the presence of an initial period of star
formation intense enough to allow the formation of massive star clusters.

mechanics, both in terms of fundamental physics and as a technology on the
brink of commercial deployment. Starting from principal schemes and initial
proofs of unconditional security for perfect systems, much effort has gone into
providing secure schemes which can cope with numerous experimental
imperfections unavoidable in real world implementations. In this paper, we
provide a comparison of various schemes and protocols. We analyse their
efficiency and performance when implemented with imperfect physical components.
We consider how experimental faults are accounted for using effective
parameters. We compare various protocols and provide guidelines as to which
components propose best advances when being improved.

712.0518 | The Tremaine-Weinberg method for pattern speeds using H-alpha emission
from ionized gas | The Fabry-Perot interferometer FaNTOmM was used at the 3.6m Canada France
Hawaii Telescope and the 1.6m Mont Megantic Telescope to obtain data cubes in
H-alpha of 9 nearby spiral galaxies from which maps in integrated intensity,
velocity, and velocity dispersion were derived. We then applied the
Tremaine-Weinberg method, in which the pattern speed can be deduced from its
velocity field, by finding the integrated value of the mean velocity along a
slit parallel to the major axis weighted by the intensity and divided by the
weighted mean distance of the velocity points from the tangent point measured
along the slit. The measured variables can be used either to make separate
calculations of the pattern speed and derive a mean, or in a plot of one
against the other for all the points on all slits, from which a best fit value
can be derived. Linear fits were found for all the galaxies in the sample. For
two galaxies a clearly separate inner pattern speed with a higher value, was
also identified and measured.

TN1 = 11.7 K. Besides the plateau at half-saturated magnetization (1/2 MS),
also plateaus at 1/9, 1/8 and 1/7 of MS were observed as function of applied
magnetic field B//c. From additional neutron scattering experiments on TmB4, we
suppose that those plateaus arise from a stripe structure which appears to be
coherent domain boundaries between AF ordered blocks of 7 or 9 lattice
constants. The received results suggest that the frustration among the Tm3+
magnetic ions, which maps to a geometrically frustrated Shastry-Sutherland
lattice lead to strong competition between AF and ferromagnetic (FM) order.
Thus, stripe structures in intermediate field appear to be the best way to
minimize the magnetostatic energy against other magnetic interactions between
the Tm ions combined with very strong Ising anisotropy.

712.052 | From Quantum Universal Enveloping Algebras to Quantum Algebras | The ``local'' structure of a quantum group G_q is currently considered to be
an infinite-dimensional object: the corresponding quantum universal enveloping
algebra U_q(g), which is a Hopf algebra deformation of the universal enveloping
algebra of a n-dimensional Lie algebra g=Lie(G). However, we show how, by
starting from the generators of the underlying Lie bialgebra (g,\delta), the
analyticity in the deformation parameter(s) allows us to determine in a unique
way a set of n ``almost primitive'' basic objects in U_q(g), that could be
properly called the ``quantum algebra generators''. So, the analytical
prolongation (g_q,\Delta) of the Lie bialgebra (g,\delta) is proposed as the
appropriate local structure of G_q. Besides, as in this way (g,\delta) and
U_q(g) are shown to be in one-to-one correspondence, the classification of
quantum groups is reduced to the classification of Lie bialgebras. The su_q(2)
and su_q(3) cases are explicitly elaborated.

712.0521 | Bernoulli coding map and almost sure invariance principle for
endomorphisms of $\mathbb{P}^k$ | Let $f$ be an holomorphic endomorphism of $\mathbb{P}^k$ and $\mu$ be its
measure of maximal entropy. We prove an Almost Sure Invariance Principle for
the systems $(\mathbb{P}^k,f,\mu)$. Our class $\cal{U}$ of observables includes
the H\"older functions and unbounded ones which present analytic singularities.
The proof is based on a geometric construction of a Bernoulli coding map
$\omega: (\Sigma, s, \nu) \to (\mathbb{P}^k,f,\mu)$. We obtain the invariance
principle for an observable $\psi$ on $(\mathbb{P}^k,f,\mu)$ by applying
Philipp-Stout's theorem for $\chi = \psi \circ \omega$ on $(\Sigma, s, \nu)$.
The invariance principle implies the Central Limit Theorem as well as several
statistical properties for the class $\cal{U}$. As an application, we give a
\emph{direct} proof of the absolute continuity of the measure $\mu$ when it

712.0523 | Early Growth of Massive Black Holes in Quasars | Episodic activity of quasars is driving growth of supermassive black holes
(SMBHs) via accretion of baryon gas. In this Letter, we develop a simple method
to analyse the duty cycle of quasars up to redshift $z\sim 6$ universe from
luminosity functions (LFs). We find that the duty cycle below redshift $z\sim
2$ follows the cosmic history of star formation rate (SFR) density. Beyond
$z\sim 2$, the evolutionary trends of the duty cycle are just opposite to that
of the cosmic SFR density history, implying the role of feedback from black
hole activity. With the duty cycle, we get the net lifetime of quasars ($z\le
5$) about $\sim 10^9$yrs. Based on the local SMBHs, the mean mass of SMBHs is
obtained at any redshifts and their seeds are of $10^5\sunm$ at the
reionization epoch ($z_{\rm re}$) of the universe through the conservation of
the black hole number density in comoving frame. We find that primordial black
holes ($\sim 10^3\sunm$) are able to grow up to the seeds via a moderate
super-Eddington accretion of $\sim 30$ times of the critical rate from $z=24$

712.0524 | The record-breaking rotational braking of the He strong CP star HD 37776 | We study the long-term light and spectral variations in the He-strong
magnetic chemically peculiar star HD 37776 (V901 Ori) to search for changes of
its 1.5387 d period in 1976-2007. We analyze all published photometric
observations and spectrophotometry in the HeI 4026 A line. The data were
supplmented with 506 new (U)VB observations obtained during the last 2
observing seasons, 66 estimates of HeI equivalent widths on 23 CFHT
spectrograms and 35 of the 6-m Zeeman spectrograms. All the 1895 particular
observations heve been processed simultaneously. We confirm the previously
suspected increase of the period in HD 37776 which is a record-breaking among
CP stars. The mean rate of the period increase during the last 31 years is
0.541+-0.020 s per year. We interpret this ongoing period increase as the
slowing down of the star's surface rotation due to momentum loss through events
and processes in its magnetosphere.

712.0529 | Light Hadron Spectrum in the Instanton Liquid Model | We review our recent study of the role played by the chiral interactions
induced by instantons, in the lowest-lying sector of the light hadron spectrum.
We discuss how the ordering of the lowest meson and baryon excitations is
explained by the structure of the instanton-induced quark-quark and gluon-gluon
interaction. We focus on the pion, nucleon, vector- and axial-vector mesons,
and on the scalar glueball. We find that all these hadrons are bound in this
model and have realistic masses.

712.053 | Symmetry-broken crystal structure of elemental boron at low temperature | The crystal structure of boron is unique among chemical elements, highly
complex, and imperfectly known. Experimentalists report the beta-rhombohedral
(black) form is stable over all temperatures from absolute zero to melting.
However, early calculations found its energy to be greater than the energy of
the alpha-rhombohedral (red) form, implying beta cannot be stable at low
temperatures. Furthermore, beta exhibits partially occupied sites, seemingly in
conflict with the thermodynamic requirement that entropy vanish at low
temperature. Using electronic density functional theory methods and an
extensive search of the configuration space we find a unique, energy minimizing
pattern of occupied and vacant sites that can be stable at low temperatures but
that breaks the beta-rhombohedral symmetry. Even lower energies occur within
larger unit cells. Alternative configurations lie nearby in energy, allowing
the entropy of partial occupancy to stabilize the beta-rhombohedral structure
through a phase transition at moderate temperature.

ultrasound system with a 5.9MHz probe was used, making it possible to see
several reconstructed orthogonal viewing planes in real time. Fourteen
operators performed biopsies first under 2-D then 4-D transurethral ultrasound
(TRUS) guidance (336 biopsies). The biopsy path was modelled using segmentation
in a 3-D ultrasonographic volume. Special software was used to visualise the
biopsy paths in a reference prostate and assess the sampled area. A comparative
study was performed to examine the accuracy of the entry points and target of
the needle. Distribution was assessed by measuring the volume sampled and a
redundancy ratio of the sampled prostate. RESULTS: A significant increase in
accuracy in hitting the target zone was identified using 4-D ultrasonography as
compared to 2-D. There was no increase in the sampled volume or improvement in
the biopsy distribution with 4-D ultrasonography as compared to 2-D.
CONCLUSION: The 4-D TRUS guidance appears to show, on a synthetic model, an
improvement in location accuracy and in the ability to reproduce a protocol.
The biopsy distribution does not seem improved.

712.0532 | Poincare recurrences from the perspective of transient chaos | We obtain a description of the Poincar\'e recurrences of chaotic systems in
terms of the ergodic theory of transient chaos. It is based on the equivalence
between the recurrence time distribution and an escape time distribution
obtained by leaking the system and taking a special initial ensemble. This
ensemble is atypical in terms of the natural measure of the leaked system, the
conditionally invariant measure. Accordingly, for general initial ensembles,
the average recurrence and escape times are different. However, we show that
the decay rate of these distributions is always the same. Our results remain
valid for Hamiltonian systems with mixed phase space and validate a split of
the chaotic saddle in hyperbolic and non-hyperbolic components.

712.0533 | Spitzer photometry of discrete sources in M33 | Combining the relative vicinity of the Local Group spiral galaxy M33 with the
Spitzer images, we investigate the properties of infrared (IR) emission sites
and assess the reliability of the IR emission as a star formation tracer. We
compared the photometric results for several samples of three known types of
discrete sources (HII regions, supernovae remnants and planetary nebulae) with
theoretical diagnostic diagrams, and derived the spectral energy distribution
(from 3.6 to 24 microns) of each type of object. Moreover, we generated a
catalogue of 24 microns sources and inferred their nature from the observed and
theoretical colours of the known type sources. We estimated the star formation

include non-equilibrium phenomena in a systematic way. The machine function
ceases to exist in the large speed limit; the way, in which this limit is

712.0536 | Dynamical Influence of Bars on the Star Formation in Isolated Galaxies | Star formation depends strongly on both the local environment of galaxies and
the internal dynamics of the interstellar medium. To disentangle the two
effects, we obtained, in the framework of the AMIGA project, Halpha and Gunn r
photometric data for more than 200 spiral galaxies lying in very low-density
regions of the local Universe. We characterise the Halpha emission, tracing
current star formation, of the 45 largest and least inclined galaxies observed
for which we estimate the torques between the gas and the bulk of the optical
matter. We subsequently study the Halpha morphological aspect of these isolated

712.0538 | Detectable Signatures of Cosmic Radiative Feedback | We use a semi-analytical model to study the impact of reionization, and the
associated radiative feedback, on galaxy formation. Two feedback models have
been considered: (i) a standard prescription, according to which star formation
is totally suppressed in galaxies with circular velocity below a critical
threshold (model CF06) and (ii) a characterization based on the filtering scale
(model G00), allowing for a gradual reduction of the gas available for star
formation in low-mass galaxies. In model CF06 reionization starts at z ~ 15-20,
is 85% complete by z ~ 10; at the same z, the ionized fraction is 16% in model
G00. The models match SDSS constraints on the evolution of the neutral hydrogen
fraction at z < 7, but predict different Thomson optical depths, tau_e = 0.1017
(CF06), and 0.0631 (G00); such values are within 1 sigma of the WMAP 3-yr
determination. Both models are in remarkable good agreement with additional
existing data (evolution of Lyman-limit systems, cosmic star formation history,
high-z galaxy counts, IGM thermal history), which therefore cannot be used to
discriminate among different feedback models. Deviations among radiative
feedback prescriptions emerge when considering the expected HI 21 cm background
signal, where a ~ 15 mK absorption feature in the range 75-100 MHz is present
in model G00 and a global shift of the emission feature preceding reionization
towards larger frequencies occurs in the same model. Single dish observations
with existing or forthcoming low-frequency radio telescopes can achieve mK
sensitivity, allowing the identification of these features provided that
foregrounds can be accurately subtracted.

712.0541 | New Construction of A Family of Quasi-Twisted Two-Weight Codes | Based on cyclic and consta-cyclic simplex codes, a new explicit construction
of a family of two-weight codes is presented. These two-weight codes obtained
are in the form of 2-generator quasi-cyclic, or quasi-twisted structure. Based
on this construction, new optimal binary quasi-cyclic [195, 8, 96], [210, 8,
104] and [240, 8, 120] codes, and good QC ternary [208, 6, 135] and [221, 6,

$G=SO(n), U(n), SU(n), Sp(n)\cdot Sp(1), Sp(n), G_2$ and $Spin(7)$. Solutions
include nearly-K\"ahler, weak holonomy $G_2$, balanced SU(n) and holonomy $G$
manifolds. As an application, we find that particle probes on $AdS_4\times X$
compactifications of type IIA and 11-dimensional supergravity admit a ${\cal
W}$-type of symmetry generated by the fundamental forms. We also explore the
${\cal W}$-symmetries of string and particle actions in heterotic and common
sector supersymmetric backgrounds. In the heterotic case, the generators of the
${\cal W}$-symmetries completely characterize the solutions of the gravitino
Killing spinor equation, and the structure constants of the ${\cal W}$-symmetry
algebra depend on the solution of the dilatino Killing spinor equation.

712.0543 | A giant radio jet ejected by an ultramassive black hole in a
single-lobed radio galaxy | We report the discovery of a very unusual, highly asymmetric radio galaxy
whose radio jet, the largest yet detected, emits strongly polarized synchrotron
radiation and can be traced all the way from the galactic nucleus to the hot
spot located ~440 kpc away. This jet emanates from an extremely massive black
hole (>10^9 solar mass) and forms a strikingly compact radio lobe. No radio
lobe is detected on the side of the counterjet, even though it is similar to
the main jet in brightness up to a scale of tens of kiloparsecs. Thus, contrary
to the nearly universal trend, the brightness asymmetry in this radio galaxy
increases with distance from the nucleus. With several unusual properties,
including a predominantly toroidal magnetic field, this Fanaroff-Riley type II

712.0545 | Regulative Differentiation as Bifurcation of Interacting Cell Population | In multicellular organisms, several cell states coexist. For determining each
cell type, cell-cell interactions are often essential, in addition to
intracellular gene expression dynamics. Based on dynamical systems theory, we
propose a mechanism for cell differentiation with regulation of populations of
each cell type by taking simple cell models with gene expression dynamics. By
incorporating several interaction kinetics, we found that the cell models with
a single intracellular positive-feedback loop exhibit a cell fate switching,
with a change in the total number of cells. The number of a given cell type or
the population ratio of each cell type is preserved against the change in the
total number of cells, depending on the form of cell-cell interaction. The
differentiation is a result of bifurcation of cell states via the intercellular
interactions, while the population regulation is explained by self-consistent
determination of the bifurcation parameter through cell-cell interactions. The
relevance of this mechanism to development and differentiation in several
multicellular systems is discussed.
| q-bio.CB | in multicellular organisms several cell states coexist for determining each cell type cellcell interactions are often essential in addition to intracellular gene expression dynamics based on dynamical systems theory we propose a mechanism for cell differentiation with regulation of populations of each cell type by taking simple cell models with gene expression dynamics by incorporating several interaction kinetics we found that the cell models with a single intracellular positivefeedback loop exhibit a cell fate switching with a change in the total number of cells the number of a given cell type or the population ratio of each cell type is preserved against the change in the total number of cells depending on the form of cellcell interaction the differentiation is a result of bifurcation of cell states via the intercellular interactions while the population regulation is explained by selfconsistent determination of the bifurcation parameter through cellcell interactions the relevance of this mechanism to development and differentiation in several multicellular systems is discussed | [['in', 'multicellular', 'organisms', 'several', 'cell', 'states', 'coexist', 'for', 'determining', 'each', 'cell', 'type', 'cellcell', 'interactions', 'are', 'often', 'essential', 'in', 'addition', 'to', 'intracellular', 'gene', 'expression', 'dynamics', 'based', 'on', 'dynamical', 'systems', 'theory', 'we', 'propose', 'a', 'mechanism', 'for', 'cell', 'differentiation', 'with', 'regulation', 'of', 'populations', 'of', 'each', 'cell', 'type', 'by', 'taking', 'simple', 'cell', 'models', 'with', 'gene', 'expression', 'dynamics', 'by', 'incorporating', 'several', 'interaction', 'kinetics', 'we', 'found', 'that', 'the', 'cell', 'models', 'with', 'a', 'single', 'intracellular', 'positivefeedback', 'loop', 'exhibit', 'a', 'cell', 'fate', 'switching', 'with', 'a', 'change', 'in', 'the', 'total', 'number', 'of', 'cells', 'the', 'number', 'of', 'a', 'given', 'cell', 'type', 'or', 'the', 'population', 'ratio', 'of', 'each', 'cell', 'type', 'is', 'preserved', 'against', 'the', 'change', 'in', 'the', 'total', 'number', 'of', 'cells', 'depending', 'on', 'the', 'form', 'of', 'cellcell', 'interaction', 'the', 'differentiation', 'is', 'a', 'result', 'of', 'bifurcation', 'of', 'cell', 'states', 'via', 'the', 'intercellular', 'interactions', 'while', 'the', 'population', 'regulation', 'is', 'explained', 'by', 'selfconsistent', 'determination', 'of', 'the', 'bifurcation', 'parameter', 'through', 'cellcell', 'interactions', 'the', 'relevance', 'of', 'this', 'mechanism', 'to', 'development', 'and', 'differentiation', 'in', 'several', 'multicellular', 'systems', 'is', 'discussed']] | [-0.18734123765628924, 0.15137448230827297, 0.03267410550198955, 0.03951916738375907, -0.0042869914499151715, -0.1355100479472808, 0.1336237853069583, 0.3119692805878542, -0.27024110264639245, -0.24889336929967007, 0.052794015701187566, -0.20760411312688648, -0.2719457190049766, 0.15567382275742006, -0.053928346120189, -0.0702607339926432, 0.05456783359578468, 0.043342271290811495, 0.0896865270908255, -0.16425869725127187, 0.28441979786967514, 0.021006339913763016, 0.2906616229196022, 0.011482121115320442, 0.11902456666216438, -0.033774871113968805, 0.010806905125831196, 0.01739291094004947, -0.11859239827156862, 0.13755779049537478, 0.21078847290325176, 0.1316497768950936, 0.28246966936844, -0.5185610290938689, -0.27962642341469884, 0.09032478625598697, 0.20001439243428593, 0.14212995571986897, -0.07510974389690629, -0.17869253776950278, 0.05161774169975593, -0.1761404224154022, -0.12275683947976816, -0.024761455380760224, 0.01981773307551644, 0.08921828181849344, -0.2726886691971119, 0.13070903113111854, 0.006866159873840652, 0.10957985262696941, -0.1275348205631024, -0.08544605727491464, -0.07629240185804205, 0.2108756991600572, 0.02820564612723243, -0.03560467197755237, 0.22508111963749944, -0.12964255470684788, -0.1361021101302295, 0.37380188590858454, 0.012591081192101823, -0.2696769969900035, 0.2136664798779321, -0.1550960867316462, -0.11036788100480205, 0.14372865129175974, 0.1455269216352867, 0.05113055698435615, -0.2027907381006689, 0.023645651483273043, 0.028645321974001915, 0.1669266541376365, 0.07673022458272308, 0.006573182976241281, 0.18524797011258792, 0.2783115977783584, 0.008787769378726313, 0.07616911914032873, -0.08519404435265855, -0.1582727474246726, -0.2544216886450203, -0.13135811656765226, -0.10119390969932149, 0.04236236846442392, -0.1113705576172373, -0.18722180020420548, 0.41053719570095665, 0.025461622556947446, 0.20502322422481362, 0.03885862808732063, 0.2431109222686953, 0.06478951243614708, 0.11545655180780608, -0.054457080665469906, 0.1679326399102991, 0.14885306450751046, 0.09395918770790974, -0.3290889361804282, 0.15787525906767927, 0.09580381513130563] |
712.0546 | Low-Energy Effective Theory, Unitarity, and Non-Decoupling Behavior in a
Model with Heavy Higgs-Triplet Fields | We discuss the properties of a model incorporating both a scalar electroweak
Higgs doublet and an electroweak Higgs triplet. We construct the low-energy
effective theory for the light Higgs-doublet in the limit of small (but
nonzero) deviations in the rho parameter from one, a limit in which the triplet
states become heavy. For small deviations in the rho parameter from one,
perturbative unitarity of WW scattering breaks down at a scale inversely
proportional to the renormalized vacuum expectation value of the triplet field
(or, equivalently, inversely proportional to the square-root of the deviation
of the rho parameter from one). This result imposes an upper limit on the
mass-scale of the heavy triplet bosons in a perturbative theory; we show that
this upper bound is consistent with dimensional analysis in the low-energy
effective theory. Recent articles have shown that the triplet bosons do not
decouple, in the sense that deviations in the rho parameter from one do not
necessarily vanish at one-loop in the limit of large triplet mass. We clarify
that, despite the non-decoupling behavior of the Higgs-triplet, this model does
not violate the decoupling theorem since it incorporates a large dimensionful
coupling. Nonetheless, we show that if the triplet-Higgs boson masses are of
order the GUT scale, perturbative consistency of the theory requires the
(properly renormalized) Higgs-triplet vacuum expectation value to be so small
as to be irrelevant for electroweak phenomenology.

712.0547 | On the role of the far fields and of cosmology for the theory of
gravitation and for the dark matter problem | We give an estimate of the gravitational field of force exerted on a test
particle by the far galaxies, in the frame of the weak field approximation. In
virtue of Hubble's law, the action of the far matter turns out to be non
negligible, and even the dominant one. An extremely simplified cosmological
model is considered. A nonvanishing contribution is obtained only if the
discrete and fractal nature of the matter distribution is taken into account.
The force per unit mass acting on a test particle is found to be of the order

712.0548 | Microwave excitations associated with a wavy angular dependence of the
spin transfer torque : model and experiments | The spin transfer torque (STT) can lead to steady precession of magnetization
without any external applied field in magnetic spin valve where the magnetic
layer have very different spin diffusion length. This effect is associated with
an unusual angular dependence of the STT, called "wavy" (WAD-STT), predicted in
the frame of diffusive models of spin transfer. In this article, we present a
complete experimental characterization of the magnetization dynamics in the
presence of a WAD-STT. The results are compared to the prediction of the
magnetization dynamics obtained by single domain magnetic simulations
(macrospin approximation). The macrospin simulations well reproduced the main
static and dynamical experimental features (phase diagram, R(I) curves,
dependence of frequency with current and field) and suggest that the dynamical
excitations observed experimentally are associated with a large angle
out-of-plane precession mode. The present work validates the diffusive models
of the spin transfer and underlines the role of the spin accumulation and the
spin relaxation effects on the STT.

712.055 | GRB970228 and the class of GRBs with an initial spikelike emission: do
they follow the Amati relation? | On the basis of the recent understanding of GRB050315 and GRB060218, we
return to GRB970228, the first Gamma-Ray Burst (GRB) with detected afterglow.
We proposed it as the prototype for a new class of GRBs with "an occasional
softer extended emission lasting tenths of seconds after an initial spikelike
emission". Detailed theoretical computation of the GRB970228 light curves in
selected energy bands for the prompt emission are presented and compared with
observational BeppoSAX data. From our analysis we conclude that GRB970228 and
likely the ones of the above mentioned new class of GRBs are "canonical GRBs"
have only one peculiarity: they exploded in a galactic environment, possibly
the halo, with a very low value of CBM density. Here we investigate how
GRB970228 unveils another peculiarity of this class of GRBs: they do not
fulfill the "Amati relation". We provide a theoretical explanation within the
fireshell model for the apparent absence of such correlation for the GRBs
belonging to this new class.

noise.%the escape rate problem in the non-Markovian spatio-temporal random
noise. There is a non-trivial short memory regime, i.e., the Markovian limit
characterized by a scaling relation between the spatial and temporal
correlation lengths. In this regime, a Fokker-Planck equation is derived by
expanding the trajectory around the systematic motion and the non-Markovian
nature amounts to the systematic reduction of the potential. For a system with
the potential barrier, this fact leads to the renormalization of both the

712.0553 | Origin of the Structure of the Kuiper Belt during a Dynamical
Instability in the Orbits of Uranus and Neptune | We explore the origin and orbital evolution of the Kuiper belt in the
framework of a recent model of the dynamical evolution of the giant planets,
sometimes known as the Nice model. This model is characterized by a short, but
violent, instability phase, during which the planets were on large eccentricity
orbits. One characteristic of this model is that the proto-planetary disk must
have been truncated at roughly 30 to 35 AU so that Neptune would stop migrating
at its currently observed location. As a result, the Kuiper belt would have
initially been empty. In this paper we present a new dynamical mechanism which
can deliver objects from the region interior to ~35 AU to the Kuiper belt
without excessive inclination excitation. Assuming that the last encounter with
Uranus delivered Neptune onto a low-inclination orbit with a semi-major axis of
~27 AU and an eccentricity of ~0.3, and that subsequently Neptune's
eccentricity damped in ~1 My, our simulations reproduce the main observed
properties of the Kuiper belt at an unprecedented level.

graph $K$ whose vertex set is a set of $n$ points in $\mathbb{R}^d$, compute a
spanner of $K$ that has a ``small'' stretch factor and ``few'' edges. We
present two algorithms for this problem. The first algorithm computes a
$(5+\epsilon)$-spanner of $K$ with O(n) edges in $O(n \log n)$ time. The second
algorithm computes a $(3+\epsilon)$-spanner of $K$ with $O(n \log n)$ edges in
$O(n \log n)$ time. The latter result is optimal: We show that for any $2 \leq
k \leq n - \Theta(\sqrt{n \log n})$, spanners with $O(n \log n)$ edges and
stretch factor less than 3 do not exist for all complete $k$-partite geometric
graphs.

712.0555 | Photometrically simply behaving mCP stars | We analyzed uvby and Hp light curves of 19 well observed magnetic CP stars
selected from the "On-line database of photometric observations of mCP stars"
of which light curves in all the five colours were similar. We assumed that
among these photometrically simply behaving (PSB) stars could be found such
ones which have a single photometric spot. The insight into such simple
situations would help us to comprehend more complicated cases. Light curves of
the 19 PSB mCP stars proved to be generally nearly symmetric but surprisingly
diverse. The analysis shows that only in the case of HD 110956B, HD 188041, and
perhaps HD 193722 we are able to explain their photometric behaviour by a

Mixtures | We study the kinetics of the first order phase separation transition in
boson-fermion cold-atom mixtures. At sufficiently low temperatures such a
transition is driven by quantum fluctuations responsible for the formation of
critical nuclei of a stable phase. Based on a microscopic description of
interacting boson-fermion mixtures we derive an effective action for the
critical droplet and obtain an asymptotic expression for the nucleation rate in
the vicinity of the phase transition and near the spinodal instability of the
mixed phase. We also discuss effects of dissipation which play a dominant role
close to the transition point, and identify the regimes where quantum
nucleation can be experimentally observed in cold-atom systems.

projective manifolds. Furthermore, a description of Lomadze's compactification
as a Quot scheme is given, whereas Helmke's compactification is shown to be an
algebraic Grassmann bundle over a Quot scheme. This gives an algebro-geometric
description of both compactifications. As an application, we determine the
cohomology ring of Helmke's compactification and prove that the two
compactifications are not isomorphic when the number of outputs is positive.

712.0559 | Signature of the Overhauser field on the coherent spin dynamics of
donor-bound electron in a single CdTe quantum well | We have studied the coherent spin dynamics in an oblique magnetic field of
electrons localized on donors and placed in the middle of a single CdTe quantum
well, by using a time-resolved optical technique: the photo-induced Faraday
rotation. We showed that this dynamics is affected by a weak Overhauser field
created via the hyperfine interaction of optically spin-polarized donor-bound
electrons with the surrounding nuclear isotopes carrying non-zero spins. We
have measured this nuclear field, which is on the order of a few mT and can
reach a maximum experimental value of 9.4 mT. This value represents 13 % of the
maximal nuclear polarization, and corresponds also to 13 % of maximal
electronic polarization.

A minor part formed sintered aggregates of 50 to 500 micrometer. In a few
experiments melt spherules having sizes smaller than 180 micrometer in diameter
(and, generally, interior voids) were formed; the highest spherule fraction was
obtained with metallic Ni. Our experiments indicate that chondrule formation by
electric current or by particle bombardment inside a discharge channel is
unlikely.

712.0562 | Investigating electron interacting dark matter | Some extensions of the Standard Model provide Dark Matter candidate particles
which can have a dominant coupling with the lepton sector of the ordinary
matter. Thus, such Dark Matter candidate particles ($\chi^{0}$) can be directly
detected only through their interaction with electrons in the detectors of a
suitable experiment, while they are lost by experiments based on the rejection
of the electromagnetic component of the experimental counting rate. These
candidates can also offer a possible source of the 511 keV photons observed
from the galactic bulge. In this paper this scenario is investigated. Some
theoretical arguments are developed and related phenomenological aspects are
discussed. Allowed intervals and regions for the characteristic
phenomenological parameters of the considered model and of the possible
mediator of the interaction are also derived considering the DAMA/NaI data.

related to SN 2006aj. [...] I present the fitting time consuming procedure. In
order to show its sensitivity I also present two examples of fits with the same
value of B and different value of E_{e^\pm}^{tot}. We fit the X- and \gamma-ray
observations by Swift of GRB 060218 in the 0.1-150 keV energy band during the
entire time of observations from 0 all the way to 10^6 s within a unified
theoretical model. The free parameters of our theory are only three, namely the
total energy E_{e\pm}^{tot} of the e^\pm plasma, its baryon loading B \equiv
M_Bc^2/E_{e\pm}^{tot}, as well as the CircumBurst Medium (CBM) distribution. We
justify the extremely long duration of this GRB by a total energy
E_{e\pm}^{tot} = 2.32\times 10^{50} erg, a very high value of the baryon
loading B=1.0\times 10^{-2} and the effective CircumBurst Medium (CBM) density
which shows a radial dependence n_{cbm} \propto r^{-\alpha} with 1.0 \leq
\alpha \leq 1.7 and monotonically decreases from 1 to $10^{-6}$
particles/cm$^3$. We recall that this value of the $B$ parameter is the highest
among the sources we have analyzed and it is very close to its absolute upper
limit expected. [...] We also think that the smallest possible black hole,
formed by the gravitational collapse of a neutron star in a binary system, is
consistent with the especially low energetics of the class of GRBs associated
with SNe Ib/c.

712.057 | Resolving the instability of the Savvidy vacuum by dynamical gluon mass | In this paper we apply the formalism of local composite operators as
developed by Verschelde et al. in combination with a constant chromomagnetic
field as considered in the seventies by Savvidy and others. We find that a
nonzero <A_\mu^2> minimizes the vacuum energy, as in the case with no
chromomagnetic field, and that the chromomagnetic field itself is near-to zero.
The Nielsen-Olesen instability, caused by the imaginary part in the action,
also vanishes. We further investigate the effect of an external chromomagnetic
field on the value of <A_\mu^2>, finding that this condensate is destroyed by
sufficiently strong fields. The inverse scenario, where <A_\mu^2> is considered
as external, results in analogous findings: when this condensate is
sufficiently large, the induced chromomagnetic field is lowered to a
perturbative value slightly below the applied <A_\mu^2>.

712.0571 | Eternal Inflation, past and future | Cosmological inflation, if it occurred, radically alters the picture of the
`big bang', which would merely point to reheating at the end of inflation.
Moreover, this reheating may be only local, so that inflation continues
elsewhere and forever, continually spawning big-bang-like regions. This chapter
reviews this idea of `eternal inflation', then focuses on what this may mean
for the ultimate beginning of the universe. In particular, I will argue that
given eternal inflation, the universe may be free of a cosmological initial
singularity, might be eternal (and eternally inflating) to the past, and might
obey an interesting sort of cosmological time-symmetry.

sum suggests a new regularization of the gravity path integral in AdS_3,
resolves the puzzles associated with the "fareytail transform," and leads to
several new insights. We discuss constraints on the polar coefficients of
negative weight modular forms arising from modular invariance, showing how
these are related to Fourier coefficients of positive weight cusp forms. In
addition, we discuss the appearance of holomorphic anomalies in the context of
the fareytail.

712.0574 | Large deviations for local time fractional Brownian motion and
applications | Let $W^H=\{W^H(t), t \in \rr\}$ be a fractional Brownian motion of Hurst
index $H \in (0, 1)$ with values in $\rr$, and let $L = \{L_t, t \ge 0\}$ be
the local time process at zero of a strictly stable L\'evy process $X=\{X_t, t
\ge 0\}$ of index $1<\alpha\leq 2$ independent of $W^H$. The $\a$-stable local
time fractional Brownian motion $Z^H=\{Z^H(t), t \ge 0\}$ is defined by $Z^H(t)
= W^H(L_t)$. The process $Z^H$ is self-similar with self-similarity index $H(1
- \frac 1 \alpha)$ and is related to the scaling limit of a continuous time
random walk with heavy-tailed waiting times between jumps
(\cite{coupleCTRW,limitCTRW}). However, $Z^H$ does not have stationary
increments and is non-Gaussian.
In this paper we establish large deviation results for the process $Z^H$. As
applications we derive upper bounds for the uniform modulus of continuity and
the laws of the iterated logarithm for $Z^H$.

712.0575 | Voltage rectification effects in mesoscopic superconducting triangles:
experiment and modelling | The interaction of externally applied currents with persistent currents
induced by magnetic field in a mesoscopic triangle is investigated. As a
consequence of the superposition of these currents, clear voltage rectification
effects are observed. We demonstrate that the amplitude of the rectified signal
strongly depends on the configurations of the current leads with the lowest
signal obtained when the contacts are aligned along a median of the triangle.
When the contacts are aligned off-centered compared to the geometrical center,
the voltage response shows oscillations as a function of the applied field,
whose sign can be controlled by shifting the contacts. These results are in

712.0576 | Inverse problems for regular variation of linear filters, a cancellation
property for $\sigma$-finite measures and identification of stable laws | In this paper, we consider certain $\sigma$-finite measures which can be
interpreted as the output of a linear filter. We assume that these measures
have regularly varying tails and study whether the input to the linear filter
must have regularly varying tails as well. This turns out to be related to the
presence of a particular cancellation property in $\sigma$-finite measures,
which in turn, is related to the uniqueness of the solution of certain
functional equations. The techniques we develop are applied to weighted sums of
i.i.d. random variables, to products of independent random variables, and to
stochastic integrals with respect to L\'evy motions.
