710.5053 | Oxygen-isotope effect on the superconducting gap in the cuprate
superconductor Y_{1-x}Pr_xBa_2Cu_3O_{7-\delta} | The oxygen-isotope (^{16}O/^{18}O) effect (OIE) on the zero-temperature
superconducting energy gap \Delta_0 was studied for a series of
Y_{1-x}Pr_xBa_2Cu_3O_{7-\delta} samples (0.0\leq x\leq0.45). The OIE on
\Delta_0 was found to scale with the one on the superconducting transition
temperature. These experimental results are in quantitative agreement with
predictions from a polaronic model for cuprate high-temperature superconductors
and rule out approaches based on purely electronic mechanisms.

710.5057 | Dwarf nova oscillations and quasi-periodic oscillations in cataclysmic
variables -- VI. Spin rates, propellering, and coherence | We examine published observations of dwarf nova oscillations (DNOs) on the
rise and decline of outbursts and show that their rates of change are in
reasonable agreement with those predicted from the magnetic accretion model. We
find evidence for propellering in the late stages of outburst of several dwarf
novae, as shown by reductions in EUVE fluxes and from rapid increases of the
DNO periods. Reanalysis of DNOs observed in TY PsA, which had particularly
large amplitudes, shows that the apparent loss of coherence during late decline
is better described as a regular switching between two nearby periods. It is
partly this and the rapid deceleration in some systems that make the DNOs
harder to detect.
We suggest that the 28.95 s periodicity in WZ Sge, which has long been a
puzzle, is caused by heated regions in the disc, just beyond the corotation
radius, which are a consequence of magnetic coupling between the primary and
gas in the accretion disc. This leads to a possible new interpretation of the
`longer period DNOs' (lpDNOs) commonly observed in dwarf novae and nova-like
variables.

710.5059 | Can the frequency-dependent specific heat be measured by thermal
effusion methods? | It has recently been shown that plane-plate heat effusion methods devised for
wide-frequency specific-heat spectroscopy do not give the isobaric specific
heat, but rather the so-called longitudinal specific heat. Here it is shown

710.5061 | theta_C from the Dihedral Flavor Symmetries D_7 and D_14 | In [1] it has been shown that the Cabibbo angle theta_C might arise from a
dihedral flavor symmetry which is broken to different (directions of) subgroups
in the up and the down quark sector. This leads to a prediction of theta_C in
terms of group theoretical quantities only, i.e. the index n of the dihedral
group D_n, the index j of the fermion representation 2_j and the preserved
subgroups indicated by m_u and m_d. Here we construct a low energy model which
incorporates this idea. The gauge group is the one of the Standard Model and
D_7 x Z_2 ^(aux) serves as flavor symmetry. The additional Z_2 ^(aux) is
necessary in order to maintain two sets of Higgs fields, one which couples only
to up quarks and another one coupling only to down quarks. We assume that D_7
is broken spontaneously at the electroweak scale by vacuum expectation values
of SU(2)_L doublet Higgs fields. The quark masses and mixing parameters can be
accommodated well. Furthermore, the potential of the Higgs fields is studied
numerically in order to show that the required configuration of the vacuum
expectation values can be achieved. We also comment on more minimalist models
which explain the Cabibbo angle in terms of group theoretical quantities, while
theta_{13}^q and theta_{23}^q vanish at leading order. Finally, we perform a
detailed numerical study of the lepton mixing matrix V_{MNS} in which one of
its elements is entirely determined by the group theory of a dihedral symmetry.
Thereby, we show that nearly tri-bi-maximal mixing can also be produced by a
dihedral flavor group with preserved subgroups.

710.5062 | Abstract Hermitian Algebras I. Spectral Resolution | We refer to the real Jordan Banach algebra of bounded Hermitian operators on
a Hilbert space as a Hermitian algebra. We define an abstract Hermitian algebra
(AH-algebra) to be the directed group of an e-ring that contains a
semitransparent element, has the quadratic annihilation property, and satisfies
a Vigier condition on pairwise commuting ascending sequences. All of this
terminology is explicated in this article, where we launch a study of
AH-algebras. Here we establish the fundamental properties of AH-algebras,
including the existence of polar decompositions and spectral resolutions, and
we show that two elements of an AH-algebra commute if and only if their
spectral projections commute. We employ spectral resolutions to assess the
structure of maximal pairwise commuting subsets of an AH-algebra.

710.5063 | The William Kruskal Legacy: 1919--2005 | William Kruskal (Bill) was a distinguished statistician who spent virtually
his entire professional career at the University of Chicago, and who had a
lasting impact on the Institute of Mathematical Statistics and on the field of
statistics more broadly, as well as on many who came in contact with him. Bill
passed away last April following an extended illness, and on May 19, 2005, the
University of Chicago held a memorial service at which several of Bill's
colleagues and collaborators spoke along with members of his family and other
friends. This biography and the accompanying commentaries derive in part from
brief presentations on that occasion, along with recollections and input from
several others. Bill was known personally to most of an older generation of
statisticians as an editor and as an intellectual and professional leader. In
1994, Statistical Science published an interview by Sandy Zabell (Vol. 9,
285--303) in which Bill looked back on selected events in his professional
life. One of the purposes of the present biography and accompanying
commentaries is to reintroduce him to old friends and to introduce him for the
first time to new generations of statisticians who never had an opportunity to
interact with him and to fall under his influence.

710.5064 | Dirac quasinormal modes of a Schwarzschild black hole surrounded by free
static spherically symmetric quintessence | We evaluate the quasinormal modes of massless Dirac perturbation in a
Schwarzschild black hole surrounded by the free static spherically symmetric
quintessence by using the third-order WKB approximation. The result shows that
due to the presence of quintessence, the massless field damps more slowly. The
real part of the quasinormal modes increases and the the absolute value of the
imaginary part increases when the state parameter $w_q$ increases. In other
words, the massless Dirac field decays more rapidly for the larger $w_q$. And

710.5066 | Pointwise multipliers in Hardy-Orlicz spaces, and interpolation | We study multipliers of Hardy-Orlicz spaces $\mH_{\Phi}$ which are strictly
contained between $\bigcup_{p>0}H^p$ and so-called ``big'' Hardy-Orlicz spaces.
Big Hardy-Orlicz spaces, carrying an algebraic structure, are equal to their
multiplier algebra, whereas in classical Hardy spaces $H^p$, the multipliers
reduce to $H^{\infty}$. For Hardy-Orlicz spaces $\mH_{\Phi}$ between these two
extremal situations and subject to some conditions, we exhibit multipliers that
are in Hardy-Orlicz spaces the defining functions of which are related to
$\Phi$. Even if the results do not entirely characterize the multiplier
algebra, some examples show that we are not very far from precise conditions.
In certain situations we see how the multiplier algebra grows in a sense from
$\Hi$ to big Hardy-Orlicz spaces when we go from classical $H^p$ spaces to big
Hardy-Orlicz spaces. However, the multiplier algebras are not always ordered as
their underlying Hardy-Orlicz spaces. Such an ordering holds in certain
situations, but examples show that there are large Hardy-Orlicz spaces for
which the multipliers reduce to $\Hi$ so that the multipliers do in general not
conserve the ordering of the underlying Hardy-Orlicz spaces. We apply some of
the multiplier results to construct Hardy-Orlicz spaces close to
$\bigcup_{p>0}H^p$ and for which the free interpolating sequences are no longer
characterized by the Carleson condition which is well known to characterize
free interpolating sequences in $H^p$, $p>0$.

710.5067 | Physical state condition in Quantum General Relativity as a consequence
of BRST symmetry | Quantization of systems with constraints can be carried on with several
methods. In the Dirac formulation the classical generators of gauge
transformations are required to annihilate physical quantum states to ensure
their gauge invariance. Carrying on BRST symmetry it is possible to get a
condition on physical states which, differently from the Dirac method, requires
them to be invariant under the BRST transformation. Employing this method for
the action of general relativity expressed in terms of the spin connection and
tetrad fields with path integral methods, we construct the generator of BRST
transformation associated with the underlying local Lorentz symmetry of the
theory and write a physical state condition consequence of BRST invariance. We
observe that this condition differs form the one obtained within Ashtekar's
canonical formulation, showing how we recover the latter only by a suitable
choice of the gauge fixing functionals. We finally discuss how it should be
possible to obtain all the requested physical state conditions associated with
all the underlying gauge symmetries of the classical theory using our approach.

710.5069 | Role of local fields in the optical properties of silicon nanocrystals
using the tight binding approach | The role of local fields in the optical response of silicon nanocrystals is
analyzed using a tight binding approach. Our calculations show that, at
variance with bulk silicon, local field effects dramatically modify the silicon
nanocrystal optical response. An explanation is given in terms of surface
electronic polarization and confirmed by the fair agreement between the tight
binding results and that of a classical dielectric model. From such a
comparison, it emerges that the classical model works not only for large but
also for very small nanocrystals. Moreover, the dependence on size of the

710.5071 | Exponential Metric Fields | The Laser Interferometer Space Antenna (LISA) mission will use advanced
technologies to achieve its science goals: the direct detection of
gravitational waves, the observation of signals from compact (small and dense)
stars as they spiral into black holes, the study of the role of massive black
holes in galaxy evolution, the search for gravitational wave emission from the
early Universe. The gravitational red-shift, the advance of the perihelion of
Mercury, deflection of light and the time delay of radar signals are the
classical tests in the first order of General Relativity (GR). However, LISA
can possibly test Einstein's theories in the second order and perhaps, it will
show some particular feature of non-linearity of gravitational interaction. In
the present work we are seeking a method to construct theoretical templates
that limit in the first order the tensorial structure of some metric fields,
thus the non-linear terms are given by exponential functions of gravitational
strength. The Newtonian limit obtained here, in the first order, is equivalent
to GR.

710.5073 | Scale dependence of cosmological backreaction | Due to the non-commutation of spatial averaging and temporal evolution,
inhomogeneities and anisotropies (cosmic structures) influence the evolution of
the averaged Universe via the cosmological backreaction mechanism. We study the
backreaction effect as a function of averaging scale in a perturbative approach
up to higher orders. We calculate the hierarchy of the critical scales, at
which 10% effects show up from averaging at different orders. The dominant
contribution comes from the averaged spatial curvature, observable up to scales
of 200 Mpc. The cosmic variance of the local Hubble rate is 10% (5%) for
spherical regions of radius 40 (60) Mpc. We compare our result to the one from
Newtonian cosmology and Hubble Space Telescope Key Project data.

710.5075 | Coherent Pion Production by Neutrinos | I concentrate in this article on the reaction--coherent pion production by
neutrinos incident on nuclei. A special effort is made in order to describe the
approximations entering the calculation. I conclude that the reaction is well
understood and with appropriate data for hadronic reactions is can be computed

analyzed for the case of field theories used to describe phase separated

an interfacial free energy which contains the mean and the Gaussian curvature

710.5078 | Two-step Doppler cooling of a three-level ladder system with an
intermediate metastable level | Doppler laser cooling of a three-level ladder system using two near-resonant
laser fields is analyzed in the case of the intermediate level being metastable
while the upper level is short-lived. Analytical as well as numerical results
for e.g. obtainable scattering rates and achievable temperatures are presented.
When appropriate, comparisons with two-level single photon Doppler laser
cooling is made. These results are relevant to recent experimental Doppler

710.5082 | Heating of blue compact dwarf galaxies: gas distribution and
photoionization by stars in I Zw 18 | Photoionization models so far are unable to account for the high electron
temperature Te([O III]) implied by the line ratio [O III]4363A/[O III]5007A in
low-metallicity blue compact dwarf galaxies, casting doubts on the assumption
of photoionization by hot stars as the dominant source of heating of the gas in
these objects. Combinations of runs of the 1-D photoionization code NEBU are
used to explore alternative models for the giant H II region shell I Zw 18 NW.
Acceptable models are obtained, which represent schematically an incomplete
shell comprising radiation-bounded condensations embedded in a low-density
matter-bounded diffuse medium. The thermal pressure contrast between gas
components is about a factor 7. The diffuse phase can be in pressure balance
with the hot superbubble fed by mechanical energy from the inner massive star
cluster. The failure of previous modellings is ascribed to (1) the adoption of
an inadequate small-scale gas density distribution, which proves critical when
the collisional excitation of hydrogen contributes significantly to the cooling
of the gas, and possibly (2) a too restrictive implementation of Wolf-Rayet
stars in synthetic stellar cluster spectral energy distributions. A neutral gas
component heated by soft X-rays, whose power is less than 1% of the star
cluster luminosity and consistent with CHANDRA data, can explain the
low-ionization fine-structure lines detected by SPITZER. [O/Fe] is slightly
smaller in I Zw 18 NW than in Galactic Halo stars of similar metallicity and
[C/O] is correlatively large. Extra heating by, e.g., dissipation of mechanical
energy is not required to explain Te([O III]) in I Zw 18. Important
astrophysical developments are at stakes in the 5% uncertainty attached to [O
III] collision strengths.

710.5083 | Control of Interaction-Induced Dephasing of Bloch Oscillations | We report on the control of interaction-induced dephasing of Bloch
oscillations for an atomic Bose-Einstein condensate in an optical lattice under
the influence of gravity. When tuning the strength of the interaction towards
zero by means of a Feshbach resonance, the dephasing time is increased from a
few to more than twenty thousand Bloch oscillation periods. We quantify the
dephasing in terms of the width of the quasi-momentum distribution and measure
its dependence on time for different values of the scattering length.
Minimizing the dephasing allows us to realize a BEC-based atom interferometer
in the non-interacting limit. We use it for a precise determination of a
zero-crossing for the atomic scattering length and to observe collapse and
revivals of Bloch oscillations when the atomic sample is subject to a spatial
force gradient.
| cond-mat.other | we report on the control of interactioninduced dephasing of bloch oscillations for an atomic boseeinstein condensate in an optical lattice under the influence of gravity when tuning the strength of the interaction towards zero by means of a feshbach resonance the dephasing time is increased from a few to more than twenty thousand bloch oscillation periods we quantify the dephasing in terms of the width of the quasimomentum distribution and measure its dependence on time for different values of the scattering length minimizing the dephasing allows us to realize a becbased atom interferometer in the noninteracting limit we use it for a precise determination of a zerocrossing for the atomic scattering length and to observe collapse and revivals of bloch oscillations when the atomic sample is subject to a spatial force gradient | [['we', 'report', 'on', 'the', 'control', 'of', 'interactioninduced', 'dephasing', 'of', 'bloch', 'oscillations', 'for', 'an', 'atomic', 'boseeinstein', 'condensate', 'in', 'an', 'optical', 'lattice', 'under', 'the', 'influence', 'of', 'gravity', 'when', 'tuning', 'the', 'strength', 'of', 'the', 'interaction', 'towards', 'zero', 'by', 'means', 'of', 'a', 'feshbach', 'resonance', 'the', 'dephasing', 'time', 'is', 'increased', 'from', 'a', 'few', 'to', 'more', 'than', 'twenty', 'thousand', 'bloch', 'oscillation', 'periods', 'we', 'quantify', 'the', 'dephasing', 'in', 'terms', 'of', 'the', 'width', 'of', 'the', 'quasimomentum', 'distribution', 'and', 'measure', 'its', 'dependence', 'on', 'time', 'for', 'different', 'values', 'of', 'the', 'scattering', 'length', 'minimizing', 'the', 'dephasing', 'allows', 'us', 'to', 'realize', 'a', 'becbased', 'atom', 'interferometer', 'in', 'the', 'noninteracting', 'limit', 'we', 'use', 'it', 'for', 'a', 'precise', 'determination', 'of', 'a', 'zerocrossing', 'for', 'the', 'atomic', 'scattering', 'length', 'and', 'to', 'observe', 'collapse', 'and', 'revivals', 'of', 'bloch', 'oscillations', 'when', 'the', 'atomic', 'sample', 'is', 'subject', 'to', 'a', 'spatial', 'force', 'gradient']] | [-0.16804743928073687, 0.20856514373272975, -0.07598908998382588, 0.04917876114962961, -0.01495957825064772, -0.09352175583780716, 0.08972000930225477, 0.36437378493560985, -0.25104411080070405, -0.262744083859478, 0.021252670516718575, -0.2682055825235059, -0.0579339971441324, 0.2235550410555196, 0.035886965664303716, 0.05810081299183146, 0.028188115387985654, 0.027983920736887463, -0.07331730420418987, -0.214475028442614, 0.309563265891153, 0.05291642990160846, 0.27631837460671016, 0.06552125575774082, 0.0839476759975889, 0.047284490243658765, 0.04588847422520771, -0.042052049613134426, -0.15180072147654067, 0.07135059084446932, 0.16552482011827646, 0.001798617872268413, 0.2763257133174744, -0.439960959628231, -0.18846886274828153, 0.08177109852884755, 0.17157586692183308, 0.20993139044819117, 0.01869502774680961, -0.30476957968803065, -0.056423608446493745, -0.12752530027434908, -0.1458627151203638, -0.06526825560793055, 0.09412073738040459, 0.007793341735095689, -0.2679811105922316, 0.09534469632445976, 0.031047570610870465, 0.09650381629806802, -0.08151313862683972, -0.034549696148711846, 0.045751529350651035, 0.09423484765284229, 0.018734946688213808, 0.017673814663959838, 0.166291123273726, -0.11206713437444926, -0.07390745375023196, 0.377826282747485, -0.1481798808713255, -0.1647007033003099, 0.14956618880034622, -0.19334099163428287, -0.018006591024018373, 0.15194941041144458, 0.1273090804337919, 0.07628185469763014, -0.1146145331874846, 0.01869240871173767, -0.012856617661644563, 0.19977813596470337, 0.12074277765879576, 0.11871471596797081, 0.21537950457158414, 0.18726369932957107, 0.11330860678395821, 0.148615567581587, -0.17502204711534874, -0.09908635433142383, -0.2649410857826076, -0.12108277781005723, -0.21772305757710428, 0.10904912485839856, -0.05404183076516898, -0.16316141823137348, 0.43882483100716135, 0.15382462939261599, 0.220562814375047, 0.023815297444040578, 0.27748989909322874, 0.14681876334714505, 0.07626097385315062, -0.02139701516099387, 0.2653576901718748, 0.18026660507982314, 0.06424421020324877, -0.36636552838855563, 0.019284399263349107, -0.004619382653441845] |

710.5086 | Photodisintegration studies on p-nuclei: The case of Mo and Sm isotopes | In explosive stellar environments like supernovae, the temperatures are high
enough for the production of heavy neutron-deficient nuclei, the socalled
p-nuclei. Up to now, the knowledge of the reaction rates of p-nuclei is based
on theoretical parameterizations using statistical model calculations. At the
bremsstrahlung facility of the superconducting electron accelerator ELBE of FZ
Dresden-Rossendorf, we aim to measure the photodisintegration rates of heavy
nuclei experimentally. Photoactivation measurements on the astrophysically
relevant p-nuclei 92Mo and 144Sm have been performed with bremsstrahlung
end-point energies from 10.0 to 16.5 MeV. First experiments on the short-lived
decays following the reaction 144Sm(gamma,n) are carried out using a pneumatic
delivery system for rapid transport of activated samples. The activation yields

710.5087 | Spitzer IRS mapping of the central kpc of Centaurus A | We report on the results of infrared spectroscopic mapping observations
carried out in the nuclear region of Centaurus A (NGC5128). The 500 pc bipolar
dust shell discovered by Quillen et al.(2006) is even more clearly seen in the
11.3 micron dust emission feature than previous broad band imaging. The pure
rotational lines of molecular hydrogen other than the S(0) line are detected
above the dusty disk and associated with the oval dust shell. The molecular
hydrogen transitions indicate the presence of warm gas at temperatures
250--720K. The ratio of the dust emission features at 7.7 and 11.3 micron and
the ratio of the [NeII](12.8) and 11.3 dust emission feature are lower in the
500 pc dust shell than in the star forming disk. The clearer shell morphology
at 11.3 micron, warm molecular hydrogen emission in the shell, and variation in
line ratios in the shell compared to those in the disk, confirm
spectroscopically that this shell is a separate coherent entity and is unlikely
to be a chance superposition of dust filaments. The physical conditions in the
shell are most similar to Galactic supernova remnants where blast waves
encounter molecular clouds. The lines requiring the highest level of
ionization, [NeV] and [OIV], are detected 20--25 arcsec north-east and
south-west of the nucleus and at position angles near the radio jet axis. Fine
structure line ratios and limits from this region suggest that the medium is
low density and illuminated by a hard radiation field at low ionization
parameter. These higher S molecular hydrogen pure rotational transitions are
also particularly bright in the same region as the [OIV] and [NeV] emission.
This suggests that the gas associated with the dust shell has been excited near
the jet axis and is part of an ionization cone.

710.5088 | Orbital magnetic moment of the electron in the hydrogen atom in deformed
space with minimal length | We investigated the orbital magnetic moment of electron in the hydrogen atom
in deformed space with minimal length. It turned out that corrections to the
magnetic moment caused by deformation depend on one parameter in the presence
of two-parametric deformation. It is interesting to note that the correction to
orbital magnetic moment is similar to the correction that follows from
relativistic theory but it has an opposite sign. Using the upper bound for
minimal length obtained in previous papers we estimated the upper bound for
relative correction to orbital magnetic moment and obtained the value $\sim

710.5089 | Collapse of Flow: Probing the Order of the Phase Transition | We discuss the present collective flow signals for the phase transition to
the quark-gluon plasma (QGP) and the collective flow as a barometer for the
equation of state (EoS). We emphasize the importance of the flow excitation
function from 1 to $50 A$ GeV: here the hydrodynamic model has predicted the
collapse of the $v_1$-flow at $\sim 10 A$ GeV and of the $v_2$-flow at $\sim 40
A$ GeV. In the latter case, this has recently been observed by the NA49
collaboration. Since hadronic rescattering models predict much larger flow than
observed at this energy, we interpret this observation as potential evidence
for a first order phase transition at high baryon density $\rho_B$.

710.5091 | Effect of annealing on the hyperfine interaction in InAs/GaAs quantum
dots | The hyperfine interaction of an electron with nuclei in the annealed
self-assembled InAs/GaAs quantum dots is theoretically analyzed. For this
purpose, the annealing process, and energy structure of the quantum dots are
numerically modeled. The modeling is verified by comparison of the calculated
optical transitions and of the experimental data on photoluminescence for set
of the annealed quantum dots. The localization volume of the electron in the
ground state and the partial contributions of In, Ga, and As nuclei to the

It is established that the contribution of indium nuclei into the hyperfine
interaction becomes predominant up to high annealing temperatures (T = 980 C)
when the In content in the quantum dots does not exceed 25%. Effect of the
nuclear spin fluctuations on the electron spin polarization is numerically
modeled. Effective field of the fluctuations is found to be in good agreement
with experimental data available.

710.5093 | High Energy spectra of Seyferts and Unification schemes | The Unified Model of AGN predicts the sole difference between Seyfert 1 and
Seyfert 2 nuclei is the viewing angle with respect to an obscuring structure
around the nucleus. High energy photons above 20 keV are not affected by this
absorption if the column is Compton thin, so their 30--100 keV spectra should
be the same. However, the observed spectra at high energies appear to show a
systematic difference, with Seyfert 1's having $\Gamma \sim $2.1 whereas
Seyfert 2's are harder with $\Gamma \sim$ 1.9. We estimate the mass and
accretion rate of Seyferts detected in these high energy samples and show that
they span a wide range in $L/L_{Edd}$. Both black hole binary systems and AGN
show a correlation between spectral softness and Eddington fraction, so these
samples are probably heterogeneous, spanning a range of intrinsic spectral
indices which are hidden in individual objects by poor signal-to-noise.
However, the mean Eddington fraction for the Seyfert 1's is higher than for the
Seyfert 2's, so the samples are consistent with this being the origin of the
softer spectra seen in Seyfert 1's. We stress that high energy spectra alone
are not necessarily a clean test of Unification schemes, but that the intrinsic
nuclear properties should also change with $L/L_{Edd}$

Equation and Other Systems with Long Range Interactions | The Robert-Sommeria-Miller equilibrium statistical mechanics predicts the
final organization of two dimensional flows. This powerful theory is difficult
to handle practically, due to the complexity associated with an infinite number
of constraints. Several alternative simpler variational problems, based on
Casimir's or stream function functionals, have been considered recently. We
establish the relations between all these variational problems, justifying the

710.5096 | Galaxy Groups in the SDSS DR4: II. halo occupation statistics | We investigate various halo occupation statistics using a large galaxy group
catalogue constructed from the SDSS DR4 with an adaptive halo-based group
finder. The conditional luminosity function (CLF) is measured separately for
all, red and blue galaxies, as well as in terms of central and satellite
galaxies. The CLFs for central and satellite galaxies can be well modelled with
a log-normal distribution and a modified Schechter form, respectively. About
85% of the central galaxies and about 80% of the satellite galaxies in halos
with masses $M_h\ga 10^{14}\msunh$ are red galaxies. These numbers decrease to
50% and 40%, respectively, in halos with $M_h \sim 10^{12}\msunh$. For halos of
a given mass, the distribution of the luminosities of central galaxies, $L_c$,
has a dispersion of about 0.15 dex. The mean luminosity (stellar mass) of the
central galaxies scales with halo mass as $L_c\propto M_h^{0.17}$
($M_{*,c}\propto M_h^{0.22}$) for halos with masses $M\gg 10^{12.5}\msunh$, and
both relations are significantly steeper for less massive halos. We also
measure the luminosity (stellar mass) gap between the first and second
brightest (most massive) member galaxies, $\log L_1 - \log L_2$ ($\log
M_{*,1}-\log M_{*,2}$). These gap statistics, especially in halos with $M_h \la
10^{14.0}\msunh$, indicate that the luminosities of central galaxies are
clearly distinct from those of their satellites. The fraction of fossil groups,
defined as those groups with $\log L_1 - \log L_2\ge 0.8$, ranges from $\sim
2.5%$ for groups with $M_h\sim 10^{14}\msunh$ to 18-60% for groups with
$M_h\sim 10^{13}\msunh$. Finally, we measure the fraction of satellites, which
changes from $\sim 5.0%$ for galaxies with $\rmag\sim -22.0$ to $\sim40%$ for
galaxies with $\rmag\sim -17.0$. (abridged)

710.5097 | Galois extensions of Lubin-Tate spectra | Let E_n be the n-th Lubin-Tate spectrum at a prime p. There is a commutative
S-algebra E^{nr}_n whose coefficients are built from the coefficients of E_n
and contain all roots of unity whose order is not divisible by p. For odd
primes p we show that E^{nr}_n does not have any non-trivial connected finite
Galois extensions and is thus separably closed in the sense of Rognes. At the
prime 2 we prove that there are no non-trivial connected Galois extensions of
E^{nr}_n with Galois group a finite group G with cyclic quotient. Our results
carry over to the K(n)-local context.

710.5099 | Creation of resilient entangled states and a resource for
measurement-based quantum computation with optical superlattices | We investigate how to create entangled states of ultracold atoms trapped in
optical lattices by dynamically manipulating the shape of the lattice
potential. We consider an additional potential (the superlattice) that allows
both the splitting of each site into a double well potential, and the control
of the height of potential barrier between sites. We use superlattice
manipulations to perform entangling operations between neighbouring qubits
encoded on the Zeeman levels of the atoms without having to perform transfers
between the different vibrational states of the atoms. We show how to use
superlattices to engineer many-body entangled states resilient to collective
dephasing noise. Also, we present a method to realize a 2D resource for
measurement-based quantum computing via Bell-pair measurements. We analyze

710.5102 | Photoluminescence modification by high-order photonic band with abnormal
dispersion in ZnO inverse opal | We measured the angle- and polarization-resolved reflection and
photoluminescence spectra of ZnO inverse opals. Significant enhancement of
spontaneous emission is observed. The enhanced emission not only has good
directionality but also can be linearly polarized. A detailed theoretical
analysis and numerical simulation reveal that such enhancement is caused by the
abnormal dispersion of a high-order photonic band. The frozen mode at a

710.5103 | ISM dust feedback from low to high mass stars | The dust component of the interstellar medium (ISM) has been extensively
studied in the past decades. Late-type stars have been assumed as the main
source of dust to the ISM, but recent observations show that supernova remnants
may play a role on the ISM dust feedback. In this work, I study the importance
of low and high mass stars, as well as their evolutionary phase, on the ISM
dust feedback process. I also determine the changes on the obtained results
considering different mass distribution functions and star formation history.
We describe a semi-empirical calculation of the relative importance of each
star at each evolutionary phase in the dust ejection to the ISM. I compare the
obtained results for two stellar mass distribution functions, the classic
Salpeter initial mass function and the present day mass function. I used the
evolutionary track models for each stellar mass, and the empirical mass-loss
rates and dust-to-gas ratio. The relative contribution of each stellar mass
depends on the used distribution. Ejecta from massive stars represent the most
important objects for the ISM dust replenishment using the Salpeter IMF. On the
other hand, for the present day mass function low and intermediate mass stars
are dominant. Late-type giant and supergiant stars dominate the ISM dust
feedback in our actual Galaxy, but this may not the case of galaxies
experiencing high star formation rates, or at high redshifts. In those cases,
SNe are dominant in the dust feedback process.

710.5104 | Casimir forces between arbitrary compact objects: Scalar and
electromagnetic field | We develop an exact method for computing the Casimir energy between arbitrary
compact objects, both with boundary conditions for a scalar field and
dielectrics or perfect conductors for the electromagnetic field. The energy is
obtained as an interaction between multipoles, generated by quantum source or
current fluctuations. The objects' shape and composition enter only through
their scattering matrices. The result is exact when all multipoles are
included, and converges rapidly. A low frequency expansion yields the energy as
a series in the ratio of the objects' size to their separation. As examples, we
obtain this series for two spheres with Robin boundary conditions for a scalar
field and dielectric spheres for the electromagnetic field. The full

710.5105 | Soft masses in superstring models with anomalous U(1) symmetries | We analyze the general structure of soft scalar masses emerging in
superstring models involving anomalous U(1) symmetries, with the aim of
characterizing more systematically the circumstances under which they can
happen to be flavor universal. We consider both heterotic orbifold and
intersecting brane models, possibly with several anomalous and non-anomalous
spontaneously broken U(1) symmetries. The hidden sector is assumed to consist
of the universal dilaton, Kahler class and complex structure moduli, which are
supposed to break supersymmetry, and a minimal set of Higgs fields which
compensate the Fayet-Iliopoulos terms. We leave the superpotential that is
supposed to stabilize the hidden sector fields unspecified, but we carefully
take into account the relations implied by gauge invariance and the constraints
required for the existence of a metastable vacuum with vanishing cosmological
constant. The results are parametrized in terms of a constrained Goldstino
direction, suitably defined effective modular weights, and the U(1) charges and
shifts. We show that the effect induced by vector multiplets strongly depends
on the functional form of the Kahler potential for the Higgs fields. We find in
particular that whenever these are charged matter fields, like in heterotic
models, the effect is non-trivial, whereas when they are shifting moduli
fields, like in certain intersecting brane models, the effect may vanish.

710.5106 | The dark connection between the Canis Major dwarf, the Monoceros ring,
the gas flaring, the rotation curve and the EGRET excess of diffuse Galactic
Gamma Rays | The excess of diffuse galactic gamma rays above 1 GeV, as observed by the
EGRET telescope on the NASA Compton Gamma Ray Observatory, shows all the key
features from Dark Matter (DM) annihilation: (i) the energy spectrum of the
excess is the same in all sky directions and is consistent with the gamma rays
expected for the annihilation of WIMPs with a mass between 50-100 GeV; (ii) the
intensity distribution of the excess in the sky is used to determine the halo
profile, which was found to correspond to the usual profile from N-body
simulations with additional substructure in the form of two doughnut-shaped
structures at radii of 4 and 13 kpc; (iii) recent N-body simulations of the
tidal disruption of the Canis Major dwarf galaxy show that it is a perfect
progenitor of the ringlike Monoceros tidal stream of stars at 13 kpc with ring
parameters in agreement with the EGRET data; (iiii) the mass of the outer ring
is so large, that its gravitational effects influence both the gas flaring and

710.5107 | Multi-gluon field approach of QCD | The decay of 2-gluon colour singlets in quarks: 2g --> q-qbar +2q-2qbar has
been simulated with the Monte-Carlo method, taking into account an effective
1-gluon exchange interaction between the emitted quarks, which was folded with
a 2-gluon density determined self-consistently. 2-gluon densities were found
with different radii, which correspond to 0^{++} glueballs of the size of light
q-qbar, s-sbar, c-cbar, b-bbar, and heavier q-qbar systems. Binding potentials
between the two gluons have been deduced, which are consistent with the
confinement potential from lattice results. However, self-consistency for the
deduction of 2-gluon densities requires massless (or very light) quarks for all
flavours. The masses are given by the binding energies of quarks and gluons,
yielding excitation spectra of 0^{++} glueballs and Phi, J/Psi, and Upsilon
states consistent with observation. The sum of q-q potentials yields a strong
coupling alpha_s consistent with the available data up to large momenta. The
nucleon is described by a gluonium state coupled to 3 valence quarks, yielding
ground state and radial excitations consistent with experiment. Finally, we
discuss the compressibility of the nucleon and relate it to that of nuclear
matter.

710.5111 | Fermionic NNLO contributions to Bhabha scattering | We derive the two-loop corrections to Bhabha scattering from heavy fermions
using dispersion relations. The double-box contributions are expressed by three
kernel functions. Convoluting the perturbative kernels with fermionic threshold
functions or with hadronic data allows to determine numerical results for small
electron mass m_e, combined with arbitrary values of the fermion mass m_f in
the loop, $m_e^2<<s,t,m_f^2$, or with hadronic insertions. We present numerical

710.5112 | Cosmological Studies with Radio Galaxies and Supernovae | Physical sizes of extended radio galaxies can be employed as a cosmological
"standard ruler", using a previously developed method. Eleven new radio
galaxies are added to our previous sample of nineteen sources, forming a sample
of thirty objects with redshifts between 0 and 1.8. This sample of radio
galaxies are used to obtain the best fit cosmological parameters in a
quintessence model in a spatially flat universe, a cosmological constant model
that allows for non-zero space curvature, and a rolling scalar field model in a
spatially flat universe. Results obtained with radio galaxies are compared with
those obtained with different supernova samples, and with combined radio galaxy
and supernova samples. Results obtained with different samples are consistent,
suggesting that neither method is seriously affected by systematic errors. Best
fit radio galaxy and supernovae model parameters determined in the different
cosmological models are nearly identical, and are used to determine
dimensionless coordinate distances to supernovae and radio galaxies, and
distance moduli to the radio galaxies. The distance moduli to the radio
galaxies can be combined with supernovae samples to increase the number of
sources, particularly high-redshift sources, in the samples. The constraints
obtained here with the combined radio galaxy plus supernovae data set in the
rolling scalar field model are quite strong. The best fit parameter values
suggest a value of omega is less than about 0.35, and the model parameter alpha
is close to zero; that is, a cosmological constant provides a good description
of the data. We also obtain new constraints on the physics of engines that
power the large-scale radio emission.

710.5113 | Weak measurement takes a simple form for cumulants | A weak measurement on a system is made by coupling a pointer weakly to the
system and then measuring the position of the pointer. If the initial
wavefunction for the pointer is real, the mean displacement of the pointer is
proportional to the so-called weak value of the observable being measured. This
gives an intuitively direct way of understanding weak measurement. However, if
the initial pointer wavefunction takes complex values, the relationship between
pointer displacement and weak value is not quite so simple, as pointed out
recently by R. Jozsa. This is even more striking in the case of sequential weak
measurements. These are carried out by coupling several pointers at different
stages of evolution of the system, and the relationship between the products of
the measured pointer positions and the sequential weak values can become
extremely complicated for an arbitrary initial pointer wavefunction.
Surprisingly, all this complication vanishes when one calculates the cumulants
of pointer positions. These are directly proportional to the cumulants of
sequential weak values. This suggests that cumulants have a fundamental
physical significance for weak measurement.

(iron chloride and iron nitrate) with different concentrations at different
ultrasound powers. In all cases we detected a neutron radiation well higher
than the background level. The neutron production is perfectly reproducible and
can at some extent be controlled. These evidences for neutron emission
generated by cavitation support some preliminary clues for the possibility of
piezonuclear reactions (namely nuclear reactions induced by pressure and shock
waves) obtained in the last ten years. We have been able for the first time to
state some basic features of such a neutron emission induced by cavitation,
namely: 1) a marked threshold behavior in power, energy and time; 2) its
occurring without a concomitant production of gamma radiation.

710.5116 | Combining haplotypers | Statistically resolving the underlying haplotype pair for a genotype
measurement is an important intermediate step in gene mapping studies, and has
received much attention recently. Consequently, a variety of methods for this
problem have been developed. Different methods employ different statistical
models, and thus implicitly encode different assumptions about the nature of
the underlying haplotype structure. Depending on the population sample in
question, their relative performance can vary greatly, and it is unclear which
method to choose for a particular sample. Instead of choosing a single method,
we explore combining predictions returned by different methods in a principled
way, and thereby circumvent the problem of method selection.
We propose several techniques for combining haplotype reconstructions and
analyze their computational properties. In an experimental study on real-world
haplotype data we show that such techniques can provide more accurate and
robust reconstructions, and are useful for outlier detection. Typically, the
combined prediction is at least as accurate as or even more accurate than the
best individual method, effectively circumventing the method selection problem.

710.5119 | Determination of the Dark Matter profile from the EGRET excess of
diffuse Galactic gamma radiation | The excess above 1 GeV in the energy spectrum of the diffuse Galactic gamma
radiation, measured with the EGRET experiment, can be interpreted as the
annihilation of Dark Matter (DM) particles. The DM is distributed in a halo
around the Milky Way. Considering the directionality of the gamma ray flux it
is possible to determine the halo profile. The DM within the halo has a smooth
and a clumpy component.These components can have different profiles as
suggested by N-body simulations and the data is indeed compatible with a NFW
profile for the diffuse component and a cored profile for the clumpy
component.These DM clumps can be partly destroyed by tidal forces from
interactions with stars and the gravitational potential of the Galactic
disc.This effect mainly decreases the annihilation signal from the Galactic

710.5122 | Bulk Aluminum at High Pressure: A First-Principles Study | The behavior of metals at high pressure is of great importance to the fields
of shock physics, geophysics, astrophysics, and nuclear materials. In order to
further understand the properties of metals at high pressures we studied the
equation of state of aluminum using first-principles techniques up to 2500 GPa,
pressures within reach of the planned L.L.N.L. National Ignition Facility. Our
simulations use density-functional theory and density-functional perturbation
theory in the generalized gradient approximation at 0K. We found core overlaps
to become relevant beyond pressures of 1200 GPa. The equations of state for
three phases (fcc, bcc, and hcp) were calculated predicting the fcc-hcp,
fcc-bcc, and hcp-bcc transitions to occur at 215 GPa, 307 GPa, and 435 GPa
respectively. From the phonon dispersions at increasing pressure, we predict a

710.5123 | Constraining Spiral Structure Parameters through Galactic Pencil-beam
and Large-scale Radial Velocity Surveys | We investigate the effect of spiral structure on the Galactic disk as viewed
by pencil beams centered on the Sun, relevant to upcoming surveys such as
ARGOS, SEGUE, and GAIA. We create synthetic Galactic maps which we call Pencil
Beam Maps (PBMs) of the following observables: line-of-sight velocities, the
corresponding velocity dispersion, and the stellar number density that are
functions of distance from the observer. We show that such maps can be used to
infer spiral structure parameters, such as pattern speed, solar phase angle,
and number of arms. The mean line-of-sight velocity and velocity dispersion are
affected by up to ~35 km/s which is well within the detectable limit for
forthcoming radial velocity surveys. One can measure the pattern speed by
searching for imprints of resonances. In the case of a two-armed spiral
structure it can be inferred from the radius of a high velocity dispersion ring
situated at the 2:1 ILR. This information, however, must be combined with
information related to the velocities and stellar number density in order to
distinguish from a four-armed structure. If the pattern speed is such that the
2:1 ILR is hidden inside the Galactic bulge the 2:1 OLR will be present in the
outer Galaxy and thus can equivalently be used to estimate the pattern speed.
Once the pattern speed is known the solar angle can be estimated from the
line-of-sight velocities and the number density PBMs. Forthcoming radial
velocity surveys are likely to provide powerful constraints of the structure of
the Milky Way disk.

710.5124 | Time-dependent CP asymmetries in Bs decays at LHCb | The LHCb experiment will search for New Physics in Bs mixing. The Bs mixing
phase will be extracted from the measurement of the time-dependent CP asymmetry
in exclusive Bs decays governed by the b -> ccbar s quark-level transition.
Large New Physics effects can be discovered or excluded with the data collected
during the very first physics run of LHC. Based on Monte Carlo simulations of

710.5126 | The Dearth of low-luminosity Globular Cluster LMXBs in NGC 3379 | Our campaign of deep monitoring observations with {\it Chandra} of the nearby
elliptical galaxy NGC 3379 has lead to the detection of nine globular cluster
(GC) and 53 field low mass X-ray binaries (LMXBs) in the joint {\it
Hubble}/{\it Chandra} field of view of this galaxy. Comparing these
populations, we find a highly significant lack of GC LMXBs at the low (0.3-8
keV) X-ray luminosities (in the $\sim 10^{36}$ to $\sim 4\times10^{37}$ erg
s$^{-1}$ range) probed with our observations. This result conflicts with the
proposition that all LMXBs are formed in GCs. This lack of low-luminosity
sources in GCs is consistent with continuous LMXB formation due to stellar
interactions and with the transition from persistent to transient LMXBs. The
observed cut-off X-ray luminosity favors a predominance of LMXBs with
main-sequence donors instead of ultra-compact binaries with white-dwarf donors;
ultra-compacts could contribute significantly only if their disks are not
affected by X-ray irradiation. Our results suggest that current theories of
magnetic stellar wind braking may work rather better for the unevolved
companions of GC LMXBs than for field LMXBs and cataclysmic variables in the
Galaxy, where these companions may be somewhat evolved.

710.5128 | Testing the nonlinearity of the BVIcJHKs period-luminosity relations for
the Large Magellanic Cloud Cepheids | A number of recent works have suggested that the period-luminosity (PL)
relation for the Large Magellanic Cloud (LMC) Cepheids exhibits a controversial
nonlinear feature with a break period at 10 days. Therefore, the aim of this
Research Note is to test the linearity/nonlinearity of the PL relations for the
LMC Cepheids in BVIcJHKs band, as well as in the Wesenheit functions. We show
that simply comparing the long and short period slopes, together with their
associate d standard deviations, leads to a strictly larger error rate than
applying rigorous statistical tests such as the F-test. We applied various
statistical tests to the current published LMC Cepheid data. These statistical
tests include the F-test, the testimator test, and the Schwarz information
criterion (SIC) method. The results from these statistical tests strongly
suggest that the LMC PL relation is nonlinear in BVIcJH band but linear in the
Ks band and in the Wesenheit functions. Using the properties of period-color
relations at maximum light and multi-phase relations, we believe that the
nonlinear PL relation is not caused by extinction errors.

710.5129 | Thermal Unparticles: A New Form of Energy Density in the Universe | Unparticle $\U$ with scaling dimension $d_\U$ has peculiar thermal properties
due to its unique phase space structure. We find that the equation of state
parameter $\omega_\U$, the ratio of pressure to energy density, is given by
$1/(2d_\U +1)$ providing a new form of energy in our universe. In an expanding
universe, the unparticle energy density $\rho_\U(T)$ evolves dramatically
differently from that for photons. For $d_\U >1$, even if $\rho_\U(T_D)$ at a
high decoupling temperature $T_D$ is very small, it is possible to have a large
relic density $\rho_\U(T^0_\gamma)$ at present photon temperature $T^0_\gamma$,

interacting Bose-Einstein condensate. We strongly reduce the interaction
induced decoherence that usually limits interferometers based on trapped
condensates by tuning the s-wave scattering length almost to zero via a
magnetic Feshbach resonance. We employ a $^{39}$K condensate trapped in an
optical lattice, where Bloch oscillations are forced by gravity. With a control
of the scattering length better that 0.1 $a_0$ we achieve coherence times of
several hundreds of ms. The micrometric sizes of the atomic sample make our
sensor an ideal candidate for measuring forces with high spatial resolution.
Our technique can be in principle extended to other measurement schemes opening
new possibilities in the field of trapped atom interferometry.

710.5132 | Absolute FKBP binding affinities obtained via non-equilibrium unbinding
simulations | We compute absolute binding affinities for two ligands bound to the FKBP
protein using non-equilibrium unbinding simulations. The methodology is
straight-forward, requiring little or no modification to many modern molecular
simulation packages. The approach makes use of a physical pathway, eliminating
the need for complicated alchemical decoupling schemes. Results of this study
are promising. For the ligands studied here the binding affinities are
typically estimated within less than 4.0 kJ/mol of the target values; and the
target values are within less than 1.0 kJ/mol of experiment. These results

710.5134 | A Zassenhaus-type algorithm solves the Bogoliubov recursion | This paper introduces a new Lie-theoretic approach to the computation of
counterterms in perturbative renormalization. Contrary to the usual approach,
the devised version of the Bogoliubov recursion does not follow a linear
induction on the number of loops. It is well-behaved with respect to the
Connes-Kreimer approach: that is, the recursion takes place inside the group of
Hopf algebra characters with values in regularized Feynman amplitudes.
(Paradigmatically, we use dimensional regularization in the minimal subtraction
scheme, although our procedure is generalizable to other schemes.) The new
method is related to Zassenhaus' approach to the Baker-Campbell-Hausdorff
formula for computing products of exponentials. The decomposition of
counterterms is parametrized by a family of Lie idempotents known as the
Zassenhaus idempotents. It is shown, inter alia, that the corresponding Feynman
rules generate the same algebra as the graded components of the Connes-Kreimer
beta-function. This further extends previous work of ours (together with Jose
M. Gracia-Bondia) on the connection between Lie idempotents and renormalization
procedures, where we constructed the Connes-Kreimer beta-function by means of
the classical Dynkin idempotent.

710.5135 | New Horizons and the Onset of the Pioneer Anomaly | Analysis of the radio tracking data from the Pioneer 10/11 spacecraft at
distances between about 20 - 70 AU from the Sun has indicated the presence of
an unmodeled, small, constant, Doppler blue shift which can be interpreted as a
constant acceleration of a_P= (8.74 \pm 1.33) \times 10^{-8} cm/s^2 directed
approximately towards the Sun. In addition, there is early (roughly modeled)
data from as close in as 5 AU which indicates there may have been an onset of
the anomaly near Saturn. We observe that the data now arriving from the New
Horizons mission to Pluto and the Kuiper Belt could allow a relatively easy,
direct experimental test of whether this onset is associated with distance from
the Sun (being, for example, an effect of drag on dark matter). We strongly
urge that this test be done.

710.5137 | Dephasing in quantum chaotic transport: a semiclassical approach | We investigate the effect of dephasing/decoherence on quantum transport
through open chaotic ballistic conductors in the semiclassical limit of small
Fermi wavelength to system size ratio, $\lambda_F/L << 1$. We use the
trajectory-based semiclassical theory to study a two-terminal chaotic dot with
decoherence originating from:
(i) an external closed quantum chaotic environment,
(ii) a classical source of noise,
(iii) a voltage probe, i.e. an additional current-conserving terminal.
We focus on the pure dephasing regime, where the coupling to the external
source of dephasing is so weak that it does not induce energy relaxation. In
addition to the universal algebraic suppression of weak localization, we find
an exponential suppression of weak-localization $\propto
\exp[-\tilde{\tau}/\tau_\phi]$, with the dephasing rate $\tau_\phi^{-1}$. The
parameter $\tilde{\tau}$ depends strongly on the source of dephasing. For a
voltage probe, $\tilde{\tau}$ is of order the Ehrenfest time $\propto \ln
[L/\lambda_F ]$. In contrast, for a chaotic environment or a classical source
of noise, it has the correlation length $\xi$ of the coupling/noise potential
replacing the Fermi wavelength $\lambda_F $. We explicitly show that the Fano
factor for shot noise is unaffected by decoherence. We connect these results to
earlier works on dephasing due to electron-electron interactions, and
numerically confirm our findings.

710.5138 | Comment on: Direct space-time observation of pulse tunneling in an
electromagnetic band gap, S.Doiron,A.Hache,H.Winful | The title of this article is misleading. The authors have investigated a
resonator but not a tunneling barrier see also Refs.\cite{Winful2} The measured
superluminal group velocity and discussed is that studied on a Lorentz-Lorenz
oscillator by Sommerfeld and Brillouin a hundred years ago \cite{Brillouin}. It
is similar to the faster than light experiment by Wang et al. based also on
anomalous dispersion with a complex refractive index of a resonator
\cite{Wang}.
Tunneling, however, is understood and performed by electromagnetic evanescent
modes or by tunneling solutions of the Schr\"odinger equation, which have
purely imaginary wave numbers. The latter includes a purely imaginary
refractive index. Signals with purely evanescent frequency components can
travel at a superluminal velocity \cite{NimtzH,Nimtz1}. Inside the barrier
tunneling proceeds even instantaneously, i.e.by a process described by virtual
photons \cite{Stahlhofen}.

710.514 | Study of the Correlations Between Stocks of Different Markets | We study correlations of a set of stocks selected from both the New York and
London stock exchanges. Results are displayed using both Random Matrix Theory
approach and the graphical visualisation of the Minimal Spanning Tree. For the
set of stocks we study, cross correlations between markets do not mix the
markets significantly. Geographical differences seem to dominate the output of
a Random Matrix analysis. Only at the level of the third highest eigenvector do
we see an effect of New York on the London data with the emergence of some
common sectors with the larger eigenvectors in London and New York. The Minimal
Spanning Trees show the broad separation of the markets as reflected in the

710.5142 | On the optimality of the neighbor-joining algorithm | The popular neighbor-joining (NJ) algorithm used in phylogenetics is a greedy
algorithm for finding the balanced minimum evolution (BME) tree associated to a
dissimilarity map. From this point of view, NJ is ``optimal'' when the
algorithm outputs the tree which minimizes the balanced minimum evolution
criterion. We use the fact that the NJ tree topology and the BME tree topology
are determined by polyhedral subdivisions of the spaces of dissimilarity maps
${\R}_{+}^{n \choose 2}$ to study the optimality of the neighbor-joining
algorithm. In particular, we investigate and compare the polyhedral
subdivisions for $n \leq 8$. A key requirement is the measurement of volumes of
spherical polytopes in high dimension, which we obtain using a combination of
Monte Carlo methods and polyhedral algorithms. We show that highly unrelated
trees can be co-optimal in BME reconstruction, and that NJ regions are not
convex. We obtain the $l_2$ radius for neighbor-joining for $n=5$ and we

710.5143 | Linearizable ordinary differential equations | Our purpose in this paper is to study when a planar differential system
polynomial in one variable linearizes in the sense that it has an inverse
integrating factor which can be constructed by means of the solutions of linear
differential equations. We give several families of differential systems which
illustrate how the integrability of the system passes through the solutions of
a linear differential equation. At the end of the work, we describe some
families of differential systems which are Darboux integrable and whose inverse
integrating factor is constructed using the solutions of a second--order linear
differential equation defining a family of orthogonal polynomials.

710.5144 | Forecasting for stationary binary time series | The forecasting problem for a stationary and ergodic binary time series
$\{X_n\}_{n=0}^{\infty}$ is to estimate the probability that $X_{n+1}=1$ based
on the observations $X_i$, $0\le i\le n$ without prior knowledge of the
distribution of the process $\{X_n\}$. It is known that this is not possible if
one estimates at all values of $n$. We present a simple procedure which will
attempt to make such a prediction infinitely often at carefully selected
stopping times chosen by the algorithm. We show that the proposed procedure is

study the physics of a single spin coupled to a boson bath. In this work we
show that optical forces allow us to realize a variety of spin-boson models,
depending on the crystal geometry and the laser configuration. We study in
detail the Ohmic case, which can be implemented by illuminating a single ion
with a travelling wave. The mesoscopic character of the phonon bath in trapped
ions induces new effects like the appearance of quantum revivals in the spin

710.5147 | Heavy quark free energies for three quark systems at finite temperature | We study the free energy of static three quark systems in singlet, octet,
decuplet and average color channels in the quenched approximation and in
2-flavor QCD at finite temperature. We show that in the high temperature phase
singlet and decuplet free energies of three quark systems are well described by
the sum of the free energies of three diquark systems plus self energy
contributions of the three quarks. In the confining low temperature phase we
find evidence for a Y-shaped flux tube in SU(3) pure gauge theory, which is
less evident in 2-flavor QCD due to the onset of string breaking. We also
compare the short distance behavior of octet and decuplet free energies to the

710.5149 | Classification of Finite Dimensional Modular Lie Superalgebras with
Indecomposable Cartan Matrix | Finite dimensional modular Lie superalgebras over algebraically closed fields
with indecomposable Cartan matrices are classified under some technical, most
probably inessential, hypotheses. If the Cartan matrix is invertible, the
corresponding Lie superalgebra is simple otherwise the quotient of the derived
Lie superalgebra modulo center is simple (if its rank is greater than 1).
Eleven new exceptional simple modular Lie superalgebras are discovered. Several
features of classic notions, or notions themselves, are clarified or
introduced, e.g., Cartan matrix, several versions of restrictedness in
characteristic 2, Dynkin diagram, Chevalley generators, and even the notion of
Lie superalgebra if the characteristic is equal to 2. Interesting phenomena in
characteristic 2: (1) all simple Lie superalgebras with Cartan matrix are
obtained from simple Lie algebras with Cartan matrix by declaring several (any)
of its Chevalley generators odd; (2) there exist simple Lie superalgebras whose
even parts are solvable. The Lie superalgebras of fixed points of automorphisms
corresponding to the symmetries of Dynkin diagrams are also listed and their
simple subquotients described.

710.515 | Absorption Effects due to Spin in the Worldline Approach to Black Hole
Dynamics | We generalize the effective point particle approach to black hole dynamics to
include spin. In this approach dissipative effects are captured by degrees of
freedom localized on the wordline. The absorptive properties of the black hole
are determined by correlation functions which can be matched with the graviton
absorption cross section in the long wavelength approximation. For rotating
black holes, superradiance is responsible for the leading contribution. The
effective theory is then used to predict the power loss due to spin in the
dynamics of non-relativistic binary systems. An enhancement of three powers of
the relative velocity is found with respect to the non-rotating case. Then we
generalize the results to other type of constituents in the binary system, such
as rotating neutron stars. Finally we compute the power loss absorbed by a test
spinning black hole in a given spacetime background.

710.5152 | A random walk approach to anomalous particle and energy transport | The combined Continuous Time Random Walk (CTRW) in position and momentum
space is introduced, in the form of two coupled integral equations that
describe the evolution of the probability distribution for finding a particle
at a certain position and with a certain momentum as a function of time. The
integral equations are solved numerically with a pseudospectral method that is
based on the expansion of the unknown functions in terms of Chebyshev
polynomials. In parallel, Monte-Carlo simulation are performed. Through the
inclusion of momentum space, the combined CTRW is able to yield results on
density and temperature profile evolution, on particle and heat fluxes and
diffusivities, and on kinetic energy distributions. Depending on the choice of
the probability distributions of the particle displacements in position and
momentum space, the combined CTRW is able to model phenomena of anomalous
transport in position as well as in momentum (or energy or velocity) space. An
application is made to a toroidally confined plasma that undergoes off-center
injection of cold plasma (off-axis fueling), using two variants of the model,
the mixed model and the critical gradient model. The phenomenon of profile
stiffness is addressed, both for the density and for the temperature profile,
respectively, and the particle and energy confinement times are determined. The
analysis of the particle and heat fluxes shows that the dynamics realized in
the combined CTRW is incompatible with the classical approach of Fick's or
Fourier's law for particle and heat transport, respectively.
