710.4053 | Crossings and nesting in tangled-diagrams | A tangled-diagram over $[n]=\{1,...,n\}$ is a graph of degree less than two
whose vertices $1,...,n$ are arranged in a horizontal line and whose arcs are
drawn in the upper halfplane with a particular notion of crossings and
nestings. Generalizing the construction of Chen {\it et.al.} we prove a
bijection between generalized vacillating tableaux with less than $k$ rows and
$k$-noncrossing tangled-diagrams and study their crossings and nestings. We
show that the number of $k$-noncrossing and $k$-nonnesting tangled-diagrams are
equal and enumerate tangled-diagrams.

710.4054 | Boxy/Peanut bulges, vertical buckling and galactic bars | Boxy/peanut bulges in disk galaxies have been associated to stellar bars. In
this talk, we discuss the different properties of such bulges and their
relation with the corresponding bar, using a very large sample of a few hundred
numerical N-body simulations. We present and inter-compare various methods of
measuring the boxy/peanut bulge properties, namely its strength, shape and
possible asymmetry. Some of these methods can be applied to both simulations
and observations. Our final goal is to get correlations that will allow us to
obtain information on the boxy/peanut bulge for a galaxy viewed face-on as well
as information on the bars of galaxies viewed edge-on.

710.4055 | Possibility of Narrow High-Mass Exotic States | Narrow high-mass states can arise despite large phase space when two nearly
degenerate states are coupled to the same dominant decay mode. Mixing via a
final-state interaction loop diagram can produce one very broad state and one
narrow state. Such a situation is generic in exotic hadrons where a color
singlet with given flavor and spin quantum numbers can be constructed with two
distinct internal color couplings of quarks. The simplest realization of this
idea are the (Q Qbar q qbar) tetraquarks containing two heavy and two light
quarks. We discuss possible experimental implications, including recent data

710.4056 | Relativistic Effects in Exclusive pd Breakup Scattering at Intermediate
Energies | The relativistic Faddeev equation for three-nucleon scattering is formulated
in momentum space and directly solved in terms of momentum vectors without
employing a partial wave decomposition. Relativistic invariance is achieved by
constructing a dynamical unitary representation of the Poincar\'e group on the
three-nucleon Hilbert space. The exclusive breakup reaction at 508 MeV is
calculated based on a Malfliet-Tjon type of two-body interaction and the cross
sections are compared to measured cross sections at this energy. We find that
the magnitude of the relativistic effects can be quite large and depends on the
configurations considered. In spite of the simple nature of the model
interaction, the experimental cross sections are in surprisingly good agreement
with the predictions of the relativistic calculations. We also find that
although for specific configurations the multiple scattering series converges
rapidly, this is in general not the case.

710.4058 | Collapsing Layers on Schwarzschild-Lemaitre Geodesics | We discuss Israel layers collapsing inward from rest at infinity along
Schwarzschild-Lemaitre geodesics. The dynamics of the collapsing layer and its
equation of state are developed. There is a general equation of state which is

710.4059 | Magnetic diffusivity tensor and dynamo effects in rotating and shearing
turbulence | The turbulent magnetic diffusivity tensor is determined in the presence of
rotation or shear. The question is addressed whether dynamo action from the
shear-current effect can explain large-scale magnetic field generation found in
simulations with shear. For this purpose a set of evolution equations for the
response to imposed test fields is solved with turbulent and mean motions
calculated from the momentum and continuity equations. The corresponding
results for the electromotive force are used to calculate turbulent transport
coefficients. The diagonal components of the turbulent magnetic diffusivity
tensor are found to be very close together, but their values increase slightly
with increasing shear and decrease with increasing rotation rate. In the
presence of shear, the sign of the two off-diagonal components of the turbulent
magnetic diffusion tensor is the same and opposite to the sign of the shear.
This implies that dynamo action from the shear--current effect is impossible,
except perhaps for high magnetic Reynolds numbers. However, even though there
is no alpha effect on the average, the components of the alpha tensor display
Gaussian fluctuations around zero. These fluctuations are strong enough to
drive an incoherent alpha--shear dynamo. The incoherent shear--current effect,
on the other hand, is found to be subdominant.

710.4062 | Double complex SUSY-transformations: deformations of real potentials and
their spectral characteristics | In paper approach of double complex SUSY-transformations with not coincident
complex energies of transformation is developed, allowing to deform given real
potential $V_{1}$ with obtaining exact solutions. The explicit solutions of the
deformation of shape of the potential, its wave function at arbitrary energy,
not coincident with energies of transformation, wave functions at the energies
of transformation are obtained, condition of keeping of continuity of the
solutions and isospectral condition are determined. Using a rectangular well of
finite width with infinitely high walls as the starting $V_{1}$ with discrete
energy spectrum, by the proposed approach new types of deformation of this
potential with deformation of the energy spectrum as a whole have been
obtained. The new potential contains the rectangular well as own partial case
(with simultaneous transformation of the shape of this new potential, energy
spectrum, wave functions of all bound states, wave function at arbitrary energy
into corresponding characteristics of the rectangular well at needed choice of
parameters). Using null potential as the starting $V_{1}$ with continuous
energy spectrum, new form of reflectionless real potential has been
constructed. This potential generalizes well-known reflectionless potential of
the type $V_{\rm ref}(x) = A^{2}(1-2 {\rm sech}^{2}{Ax})$, allowing: to pull
down tails of the potential $V_{\rm ref}$ in the asymptotic regions up to zero
(with keeping of nonzero depth); to pull down continuously the depth of the
hole; to displace arbitrary along axis $x$ the hole with its passing through
zero; to create and to increase the second hole, transforming $V_{\rm ref}$
into double-well potential; to control continuously and simply the asymmetry of
the shape of such reflectionless potential.

710.4063 | Anomalous diffusion in a random nonlinear oscillator due to high
frequencies of the noise | We study the long time behaviour of a nonlinear oscillator subject to a
random multiplicative noise with a spectral density (or power-spectrum) that
decays as a power law at high frequencies. When the dissipation is negligible,
physical observables, such as the amplitude, the velocity and the energy of the
oscillator grow as power-laws with time. We calculate the associated scaling
exponents and we show that their values depend on the asymptotic behaviour of
the external potential and on the high frequencies of the noise. Our results
are generalized to include dissipative effects and additive noise.

710.4065 | The periodic bursters XB1323-619 and GS1826-24: longterm evolution of
the nuclear burning regime and comparison with theory | The majority of X-ray burst sources do not display a burst rate that
increases with luminosity as expected, but this is seen in the two clocked
bursters XB1323-619 and GS1826-24. We present a detailed investigation of these
two sources which in the case of the first source, spans 18 years. Based on
measurements of the burst rate, X-ray luminosity, the alpha-parameter and the
two time constants generally present in the burst decays, we demonstrate the
importance of the rp nuclear burning process. A detailed comparison with theory
shows that although the burst rate in each source agrees well with the
theoretical value, there is a difference of more than a factor of 5 in the
burst rate at a given luminosity between the sources. We show that the main
reason for this is that the two sources have substantially different emitting
areas on the neutron star in non-burst emission, a factor often neglected.
Variation of this area may explain the inverse relation of burst rate with
luminosity in the majority of burst sources.
| astro-ph | the majority of xray burst sources do not display a burst rate that increases with luminosity as expected but this is seen in the two clocked bursters xb1323619 and gs182624 we present a detailed investigation of these two sources which in the case of the first source spans 18 years based on measurements of the burst rate xray luminosity the alphaparameter and the two time constants generally present in the burst decays we demonstrate the importance of the rp nuclear burning process a detailed comparison with theory shows that although the burst rate in each source agrees well with the theoretical value there is a difference of more than a factor of 5 in the burst rate at a given luminosity between the sources we show that the main reason for this is that the two sources have substantially different emitting areas on the neutron star in nonburst emission a factor often neglected variation of this area may explain the inverse relation of burst rate with luminosity in the majority of burst sources | [['the', 'majority', 'of', 'xray', 'burst', 'sources', 'do', 'not', 'display', 'a', 'burst', 'rate', 'that', 'increases', 'with', 'luminosity', 'as', 'expected', 'but', 'this', 'is', 'seen', 'in', 'the', 'two', 'clocked', 'bursters', 'xb1323619', 'and', 'gs182624', 'we', 'present', 'a', 'detailed', 'investigation', 'of', 'these', 'two', 'sources', 'which', 'in', 'the', 'case', 'of', 'the', 'first', 'source', 'spans', '18', 'years', 'based', 'on', 'measurements', 'of', 'the', 'burst', 'rate', 'xray', 'luminosity', 'the', 'alphaparameter', 'and', 'the', 'two', 'time', 'constants', 'generally', 'present', 'in', 'the', 'burst', 'decays', 'we', 'demonstrate', 'the', 'importance', 'of', 'the', 'rp', 'nuclear', 'burning', 'process', 'a', 'detailed', 'comparison', 'with', 'theory', 'shows', 'that', 'although', 'the', 'burst', 'rate', 'in', 'each', 'source', 'agrees', 'well', 'with', 'the', 'theoretical', 'value', 'there', 'is', 'a', 'difference', 'of', 'more', 'than', 'a', 'factor', 'of', '5', 'in', 'the', 'burst', 'rate', 'at', 'a', 'given', 'luminosity', 'between', 'the', 'sources', 'we', 'show', 'that', 'the', 'main', 'reason', 'for', 'this', 'is', 'that', 'the', 'two', 'sources', 'have', 'substantially', 'different', 'emitting', 'areas', 'on', 'the', 'neutron', 'star', 'in', 'nonburst', 'emission', 'a', 'factor', 'often', 'neglected', 'variation', 'of', 'this', 'area', 'may', 'explain', 'the', 'inverse', 'relation', 'of', 'burst', 'rate', 'with', 'luminosity', 'in', 'the', 'majority', 'of', 'burst', 'sources']] | [-0.08883234672588759, 0.11935595578203599, -0.041776458073777764, 0.10966967335364201, -0.03869311620443188, -0.0549243268262791, 0.0828217427104668, 0.4330435364196698, -0.18781398065770807, -0.3172583598207835, 0.0952143558792563, -0.32100748711085897, -0.06006339333178094, 0.27101955122289884, -0.02861460385517672, -0.02589511377900316, 0.06913618888428207, 0.017998601187412675, -0.08707808829539003, -0.21521624006543374, 0.3118169087377426, 0.09177383385075812, 0.2515841168732715, 0.024680782093159985, 0.0651480418014509, -0.05455938692998457, -0.06973814973553195, -0.025803653991710373, -0.0978182601200877, 0.0653209567195273, 0.2418809369511423, 0.14390165345982936, 0.21899365986920674, -0.39269628101273585, -0.23535797127375477, 0.0960181526327778, 0.13775705819001846, 0.040127318068570866, -0.08242170904990767, -0.18708207187575032, 0.054321254650539344, -0.2026506779124492, -0.102538658213415, 0.10320673131299538, 0.07007707160086049, 0.058461411861561195, -0.20560441870236912, 0.12841037992961235, 0.04653452967473289, 0.0314022271474551, -0.08120205908420099, -0.06312378083099747, 0.036940319287966476, 0.07860523629770205, 0.08980266279959642, 0.07194464040201223, 0.12851292269620282, -0.14015963540292667, -0.09456068124861745, 0.3605427829145688, -0.06450162712957408, -0.04406105620890028, 0.1943782667305364, -0.21717190426605487, -0.16853055337322087, 0.15624970482520714, 0.12793154124584463, 0.10653181084328228, -0.1548380477991151, -0.03425068856551917, 0.0011316074646617238, 0.26204379836413244, 0.02393237893339941, 0.06915566636445492, 0.2226240550336695, 0.17578010201966118, 0.02452261829803213, 0.1306031744829134, -0.1887964199308023, -0.03941292323346375, -0.32993111237801875, -0.09972681191733532, -0.13515241727456231, 0.10161130924374533, -0.08477997529570269, -0.126574742336477, 0.3993048739635892, 0.10018495903064481, 0.22788045682252672, 0.05679761092872931, 0.2470245448197102, 0.13741736180878827, 0.0878408135579387, 0.10786309186641498, 0.32932204124653897, 0.10381772440765598, 0.08770689651184874, -0.23027379036069526, 0.11393110638168472, -0.009961523793703108] |
710.4066 | Noise-induced bifurcations, Multiscaling and On-Off intermittency | We present recent results on noise-induced transitions in a nonlinear
oscillator with randomly modulated frequency. The presence of stochastic
perturbations drastically alters the dynamical behaviour of the oscillator:
noise can wash out a global attractor but can also have a constructive role by
stabilizing an unstable fixed point. The random oscillator displays a rich
phenomenology but remains elementary enough to allow for exact calculations:
this system is thus a useful paradigm for the study of noise-induced
bifurcations and is an ideal testing ground for various mathematical
techniques. We show that the phase is determined by the sign of the Lyapunov
exponent (which can be calculated non-perturbatively for white noise), and we
derive the full phase diagram of the system. We also investigate the effect of
time-correlations of the noise on the phase diagram and show that a smooth
random perturbation is less efficient than white noise. We study the critical
behaviour near the transition and explain why noise-induced transitions often
exhibit intermittency and multiscaling: these effects do not depend on the
amplitude of the noise but rather on its power spectrum. By increasing or
filtering out the low frequencies of the noise, intermittency and multiscaling
can be enhanced or eliminated.

710.4067 | A low-lying scalar meson nonet in a unitarized meson model | A unitarized nonrelativistic meson model which is successful for the
description of the heavy and light vector and pseudoscalar mesons yields, in
its extension to the scalar mesons but for the same model parameters, a
complete nonet below 1 GeV. In the unitarization scheme, real and virtual
meson-meson decay channels are coupled to the quark-antiquark confinement
channels. The flavor-dependent harmonic-oscillator confining potential itself
has bound states epsilon(1.3 GeV), S(1.5 GeV), delta(1.3 GeV), kappa(1.4 GeV),
similar to the results of other bound-state qqbar models. However, the full
coupled-channel equations show poles at epsilon(0.5 GeV), S(0.99 GeV),
delta(0.97 GeV), kappa(0.73 GeV). Not only can these pole positions be
calculated in our model, but also cross sections and phase shifts in the

710.4068 | Close-up of primary and secondary asteroseismic CoRoT targets and the
ground-based follow-up observations | To optimise the science results of the asteroseismic part of the CoRoT
satellite mission a complementary simultaneous ground-based observational
campaign is organised for selected CoRoT targets. The observations include both
high-resolution spectroscopic and multi-colour photometric data. We present the
preliminary results of the analysis of the ground-based observations of three
targets. A line-profile analysis of 216 high-resolution FEROS spectra of the
delta Sct star HD 50844 reveals more than ten pulsation frequencies in the
frequency range 5-18 c/d, including possibly one radial fundamental mode (6.92
c/d). Based on more than 600 multi-colour photometric datapoints of the beta
Cep star HD180642, spanning about three years and obtained with different
telescopes and different instruments, we confirm the presence of a dominant
radial mode nu1=5.48695 c/d, and detect also its first two harmonics. We find
evidence for a second mode nu2=0.3017 c/d, possibly a g-mode, and indications
for two more frequencies in the 7-8 c/d domain. From Stromgren photometry we
find evidence for the hybrid delta Sct/gamma Dor character of the F0 star HD
44195, as frequencies near 3 c/d and 21 c/d are detected simultaneously in the
different filters.

710.4069 | Fe-doping-induced evolution of charge-orbital ordering in a
bicritical-state manganite | Impurity effects on the stability of a ferromagnetic metallic state in a
bicritical-state manganite, (La0.7Pr0.3)0.65Ca0.35MnO3, on the verge of
metal-insulator transition have been investigated by substituting a variety of
transition-metal atoms for Mn ones. Among them, Fe doping exhibits the
exceptional ability to dramatically decrease the ferromagnetic transition
temperature. Systematic studies on the magnetotransport properties and x-ray
diffraction for the Fe-doped crystals have revealed that charge-orbital
ordering evolves down to low temperatures, which strongly suppresses the
ferromagnetic metallic state. The observed glassy magnetic and transport
properties as well as diffuse phase transition can be attributed to the
phase-separated state where short-range charge-orbital-ordered clusters are
embedded in the ferromagnetic metallic matrix. Such a behavior in the Fe-doped
manganites form a marked contrast to the Cr-doping effects on

710.407 | Velocity dispersion around ellipticals in MOND | We investigate how different models that have been proposed for solving the
dark matter problem can fit the velocity dispersion observed around elliptical
galaxies, on either a small scale (~ 20kpc) with stellar tracers, such as
planetary nebulae, or large scale (~ 200kpc) with satellite galaxies as
tracers. Predictions of Newtonian gravity, either containing pure baryonic
matter, or embedded in massive cold dark matter (CDM) haloes, are compared with
predictions of the modified gravity of MOND. The standard CDM model has
problems on a small scale, and the Newtonian pure baryonic model has
difficulties on a large scale, while a fit with MOND is possible on both
scales.

obtain a good determination of the host galaxy orientation. With these new

significant correlation between the polarization position angle and the

710.4074 | Density of States for HP Lattice Proteins | The density of states contains all informations on energetic quantities of a
statistical system, such as the mean energy, free energy, entropy, and specific
heat. As a specific application, we consider in this work a simple lattice
model for heteropolymers that is widely used for studying statistical
properties of proteins. For short chains, we have derived exact results from
conformational enumeration, while for longer ones we developed a multicanonical
Monte Carlo variant of the nPERM-based chain growth method in order to directly
simulate the density of states. For simplification, only two types of monomers
with respective hydrophobic (H) and polar (P) residues are regarded and only

710.4075 | Getting More From Your Multicore: Exploiting OpenMP for Astronomy | Motivated by the emergence of multicore architectures, and the reality that
parallelism is rarely used for analysis in observational astronomy, we
demonstrate how general users may employ tightly-coupled multiprocessors in
scriptable research calculations while requiring no special knowledge of
parallel programming. Our method rests on the observation that much of the
appeal of high-level vectorized languages like IDL or MatLab stems from
relatively simple internal loops over regular array structures, and that these
loops are highly amenable to automatic parallelization with OpenMP. We discuss
how ISIS, an open-source astrophysical analysis system embedding the S-Lang
numerical language, was easily adapted to exploit this pattern. Drawing from a
common astrophysical problem, model fitting, we present beneficial speedups for
several machine and compiler configurations. These results complement our
previous efforts with PVM, and together lead us to believe that ISIS is the
only general purpose spectroscopy system in which such a range of parallelism
-- from single processors on multiple machines to multiple processors on single
machines -- has been demonstrated.

710.4076 | Some information-theoretic computations related to the distribution of
prime numbers | We illustrate how elementary information-theoretic ideas may be employed to
provide proofs for well-known, nontrivial results in number theory.
Specifically, we give an elementary and fairly short proof of the following
asymptotic result: The sum of (log p)/p, taken over all primes p not exceeding
n, is asymptotic to log n as n tends to infinity. We also give finite-n bounds

710.4077 | Elements of Algebraic Geometry and the Positive Theory of Partially
Commutative Groups | In this version small mistakes are corrected and the exposition is changed as
suggested by the referee (to appear in Canadian Journal of Mathematics).
The first main result of the paper is a criterion for a partially commutative
group $\GG$ to be a domain. It allows us to reduce the study of algebraic sets
over $\GG$ to the study of irreducible algebraic sets, and reduce the
elementary theory of $\GG$ (of a coordinate group over $\GG$) to the elementary
theories of the direct factors of $\GG$ (to the elementary theory of coordinate
groups of irreducible algebraic sets).
Then we establish normal forms for quantifier-free formulas over a
non-abelian directly indecomposable partially commutative group $\HH$.
Analogously to the case of free groups, we introduce the notion of a
generalised equation and prove that the positive theory of $\HH$ has quantifier
elimination and that arbitrary first-order formulas lift from $\HH$ to $\HH\ast
F$, where $F$ is a free group of finite rank. As a consequence, the positive
theory of an arbitrary partially commutative group is decidable.

710.4078 | Slope Stability and Exceptional Divisors of High Genus | We study slope stability of smooth surfaces and its connection with
exceptional divisors. We show that a surface containing an exceptional divisor
with arithmetic genus at least two is slope unstable for some polarisation. In
the converse direction we show that slope stability of surfaces can be tested
with divisors, and prove that for surfaces with non-negative Kodaira dimension
any destabilising divisor must have negative self-intersection and arithmetic
genus at least two. We also prove that a destabilising divisor can never be

710.408 | The fine-tuning problems of particle physics and anthropic mechanisms | Many of the classic problems of particle physics appear in a very different
light when viewed from the perspective of the multiverse. Most importantly the
two great ``fine tuning'' problems that motivate the field are far less serious
when one accounts for the required anthropic constraints which exist in a
multiverse. However, the challenge then becomes to construct a realistic
physical theory of the multiverse and test it. I describe some phenomenology of
the quark and lepton masses that may provide a window to the theory that
underlies the multiverse.

710.4081 | Opacity in compact extragalactic radio sources and its effect on
radio-optical reference frame alignment | Accurate alignment of the radio and optical celestial reference frames
requires detailed understanding of physical factors that may cause offsets
between the positions of the same object measured in different spectral bands.
Opacity in compact extragalactic jets (due to synchrotron self-absorption and
external free-free absorption) is one of the key physical phenomena producing
such an offset, and this effect is well-known in radio astronomy ("core
shift"). We have measured the core shifts in a sample of 29 bright compact
extragalactic radio sources observed using very long baseline interferometry
(VLBI) at 2.3 and 8.6 GHz. We report the results of these measurements and
estimate that the average shift between radio and optical positions of distant
quasars would be of the order of 0.1-0.2 mas. This shift exceeds positional
accuracy of GAIA and SIM. We suggest two possible approaches to carefully
investigate and correct for this effect in order to align accurately the radio
and optical positions. Both approaches involve determining a Primary Reference
Sample of objects to be used for tying the radio and optical reference frames
together.
| astro-ph | accurate alignment of the radio and optical celestial reference frames requires detailed understanding of physical factors that may cause offsets between the positions of the same object measured in different spectral bands opacity in compact extragalactic jets due to synchrotron selfabsorption and external freefree absorption is one of the key physical phenomena producing such an offset and this effect is wellknown in radio astronomy core shift we have measured the core shifts in a sample of 29 bright compact extragalactic radio sources observed using very long baseline interferometry vlbi at 23 and 86 ghz we report the results of these measurements and estimate that the average shift between radio and optical positions of distant quasars would be of the order of 0102 mas this shift exceeds positional accuracy of gaia and sim we suggest two possible approaches to carefully investigate and correct for this effect in order to align accurately the radio and optical positions both approaches involve determining a primary reference sample of objects to be used for tying the radio and optical reference frames together | [['accurate', 'alignment', 'of', 'the', 'radio', 'and', 'optical', 'celestial', 'reference', 'frames', 'requires', 'detailed', 'understanding', 'of', 'physical', 'factors', 'that', 'may', 'cause', 'offsets', 'between', 'the', 'positions', 'of', 'the', 'same', 'object', 'measured', 'in', 'different', 'spectral', 'bands', 'opacity', 'in', 'compact', 'extragalactic', 'jets', 'due', 'to', 'synchrotron', 'selfabsorption', 'and', 'external', 'freefree', 'absorption', 'is', 'one', 'of', 'the', 'key', 'physical', 'phenomena', 'producing', 'such', 'an', 'offset', 'and', 'this', 'effect', 'is', 'wellknown', 'in', 'radio', 'astronomy', 'core', 'shift', 'we', 'have', 'measured', 'the', 'core', 'shifts', 'in', 'a', 'sample', 'of', '29', 'bright', 'compact', 'extragalactic', 'radio', 'sources', 'observed', 'using', 'very', 'long', 'baseline', 'interferometry', 'vlbi', 'at', '23', 'and', '86', 'ghz', 'we', 'report', 'the', 'results', 'of', 'these', 'measurements', 'and', 'estimate', 'that', 'the', 'average', 'shift', 'between', 'radio', 'and', 'optical', 'positions', 'of', 'distant', 'quasars', 'would', 'be', 'of', 'the', 'order', 'of', '0102', 'mas', 'this', 'shift', 'exceeds', 'positional', 'accuracy', 'of', 'gaia', 'and', 'sim', 'we', 'suggest', 'two', 'possible', 'approaches', 'to', 'carefully', 'investigate', 'and', 'correct', 'for', 'this', 'effect', 'in', 'order', 'to', 'align', 'accurately', 'the', 'radio', 'and', 'optical', 'positions', 'both', 'approaches', 'involve', 'determining', 'a', 'primary', 'reference', 'sample', 'of', 'objects', 'to', 'be', 'used', 'for', 'tying', 'the', 'radio', 'and', 'optical', 'reference', 'frames', 'together']] | [-0.09355224191216426, 0.10149825525828203, -0.04528527529541887, 0.08462779970358174, -0.11138314394659157, -0.08429379286349746, 0.07286191817457224, 0.4946634594435241, -0.20692389161920563, -0.36429807018635973, 0.057053326299587676, -0.2739151598527859, -0.03455997082585006, 0.19196268934809135, -0.03486026835359507, -0.006682341772336829, 0.05303883863466915, -0.07589909377228996, -0.05300892295483497, -0.1447787958152571, 0.2563576276656135, 0.12207697036460378, 0.2550037112244863, 0.008884944328196389, 0.10002778852253226, -0.057374068099142465, -0.12608806734988834, -0.005450442733274678, -0.045562059634728855, 0.1023798086969866, 0.2706829888396239, 0.09612325051178534, 0.20411175915385704, -0.36349109424458026, -0.2058229453619675, 0.09472037682514954, 0.13875794850979106, 0.08657937448977895, 0.008118226557922692, -0.2903919289721239, 0.06375581355822026, -0.15349590368134805, -0.15276113619743767, 0.03714435555943219, 0.06723815656272368, 0.06428334541029512, -0.20570874842157388, 0.09835873580324637, 0.009136352106655216, 0.09534165059416265, -0.12438492547183977, -0.10406175420993129, 0.028655752355474875, 0.1832493974137946, -0.012460970010353243, 0.07842941460920508, 0.13721523495748808, -0.09802724870505854, -0.10781182573403174, 0.44722707272049483, -0.05444400617063551, -0.06027153568437039, 0.20533113986879223, -0.2061798088568247, -0.1675113900235754, 0.1355473657709541, 0.18506463230416537, 0.07745795212107273, -0.12420272119316972, -0.07227058575875363, 0.031243734533956413, 0.22307020064645924, 0.09181563304684594, 0.14415744949384765, 0.28743733256255505, 0.10529532018749012, 0.026203645341950705, 0.11029432247140271, -0.2508748877335782, 0.014195735763303283, -0.2680761890326716, -0.06768745720170447, -0.15251786469527598, 0.07474822070354879, -0.10997547959500403, -0.10058226999083512, 0.374465081506635, 0.14976992053117888, 0.1880428608885761, 0.0044939267662180175, 0.3429574785638327, 0.07350507455596458, 0.09224239163006008, 0.08656962505557526, 0.3494184513676301, 0.12098847154270079, 0.0982210628062192, -0.20883051046607015, 0.04576737105341281, -0.02878902274404921] |

$\ell_1$-penalized functionals | The problem of assessing the performance of algorithms used for the
minimization of an $\ell_1$-penalized least-squares functional, for a range of

well-conditioned and ill-conditioned problems are used in the comparison, and
the contrast between these two categories is highlighted.

710.4084 | Minimal Gromov--Witten ring | We build the abstract theory of Gromov-Witten invariants of genus 0 for
quantum minimal Fano varieties (a minimal natural (with respect to
Gromov-Witten theory) class of varieties). In particular, we consider ``the
minimal Gromov-Witten ring'', i. e. a commutative algebra with generators and
relations of the form used in the Gromov-Witten theory of Fano variety (of
unspecified dimension). Gromov-Witten theory of any quantum minimal variety is
a homomorphism of this ring to $\mathbb C$. We prove the Abstract
Reconstruction Theorem which states the particular isomorphism of this ring

710.4086 | The importance of radiation pressure in the launching of jets | Based on the results of applying the extended ADC emission model to three
Z-track sources: GX340+0, GX5-1 and CygX-2, we propose an explanation of the
Z-track sources in which the Normal and Horizontal Branches are dominated by
the increasing radiation pressure of the neutron star. The emitted flux becomes
several times super-Eddington at the Hard Apex and Horizontal Branch and we
suggest that the inner accretion disk is disrupted by this and that part of the
accretion flow is diverted vertically. This position on the Z-track is exactly
the position where radio emission is detected showing the presence of jets. We
thus propose that high radiation pressure is a necessary condition for the
launching of jets. We also show that flaring must consist of unstable nuclear
burning and that the mass accretion rate per unit emitting area of the neutron
star mdot at the onset of flaring agrees well with the critical theoretical
value at which burning becomes unstable.

710.4088 | Comment on ``Reduction of static field equation of Faddeev model to
first order PDE'', arXiv:0707.2207 | The authors of the article Phys. Lett. B 652 (2007) 384, (arXiv:0707.2207),
propose an interesting method to solve the Faddeev model by reducing it to a
set of first order PDEs. They first construct a vectorial quantity $\bm \alpha
$, depending on the original field and its first derivatives, in terms of which
the field equations reduce to a linear first order equation. Then they find
vectors $\bm \alpha_1$ and $\bm \alpha_2$ which identically obey this linear
first order equation. The last step consists in the identification of the $\bm
\alpha_i$ with the original $\bm \alpha$ as a function of the original field.
Unfortunately, the derivation of this last step in the paper cited above
contains an error which invalidates most of its results.

also able to show that if $R$ is an excellent local domain and $\Tor_i^R(k,R^+)

710.4091 | Lepton Flavour Violation in SUSY-seesaw: an update | Here we update the predictions for lepton flavour violating tau and muon
decays, $l_j \to l_i \gamma$, $l_j \to 3 l_i$, and $\mu-e$ conversion in
nuclei. We work within a SUSY-seesaw context where the particle content of the
Minimal Supersymmetric Standard Model is extended by three right handed
neutrinos plus their corresponding SUSY partners, and where a seesaw mechanism
for neutrino mass generation is implemented. Two different scenarios with
either universal or non-universal soft supersymmetry breaking Higgs masses at
the gauge coupling unification scale are considered. After comparing the

710.4092 | Modifcation of single molecule fluorescence close to a nanostructure:
radiation pattern, spontaneous emission and quenching | The coupling of nanostructures with emitters opens ways for the realization
of man-made subwavelength light emitting elements. In this article, we
investigate the modification of fluorescence when an emitter is placed close to
a nanostructure. In order to control the wealth of parameters that contribute
to this process, we have combined scanning probe technology with single
molecule microscopy and spectroscopy. We discuss the enhancement and reduction
of molecular excitation and emission rates in the presence of a dielectric or
metallic nanoparticle and emphasize the role of plasmon resonances in the
latter. Furthermore, we examine the spectral and angular emission
characteristics of the molecule-particle system. Our experimental findings are
in excellent semi-quantitative agreement with the outcome of theoretical
calculations. We express our results in the framework of optical nanoantennae
and propose arrangements that could lead to the modification of spontaneous
emission by more than 1000 times.

710.4094 | Deep Optical Imaging of Starbursting "Transition" Dwarf Galaxies | A subgroup of dwarf galaxies have characteristics of a possible evolutionary
transition between star-forming systems and dwarf ellipticals. These systems
host significant starbursts in combination with smooth, elliptical outer
envelopes and small HI content; they are low on gas and unlikely to sustain
high star formation rates over significant cosmic time spans. We explore
possible origins of such starburst "transition" dwarfs using moderately deep
optical images. While galaxy-galaxy interactions could produce these galaxies,
no optical evidence exists for tidal debris or other outer disturbances, and
they also lack nearby giant neighbors which could supply recent perturbations.
Colors of the outer regions indicate that star formation ceased > 1 Gyr in the
past, a longer time span than can be reasonably associated with the current
starbursts. We consider mechanisms where the starbursts are tied either to
interactions with other dwarfs or to the state of the interstellar medium, and
discuss the possibility of episodic star formation events associated with gas
heating and cooling in low specific angular momentum galaxies.

710.4096 | A density matrix approach to the dynamical properties of a two-site
Holstein model | The two-site Holstein model represents a first non-trivial paradigm for the
interaction between an itinerant charge with a quantum oscillator, a very
common topic in different ambits. Exact results can be achieved both
analytically and numerically, nevertheless it can be useful to compare them
with approximate, semi-classical techniques in order to highlight the role of
quantum effects. In this paper we consider the adiabatic limit in which the
oscillator is very much slow than the electron. A density matrix approach is
introduced for studying the charge dynamics and the exact results are compared
with two different approximations: a Born-Oppenheimer-based Static
Approximation for the oscillator (SA) and a Quantum-classical (QC) dynamics.

710.4099 | Uniqueness of Bohmian Mechanics, and Solutions From Probability
Conservation | We show that one-dimensional Bohmian mechanics is unique, in that, the Bohm
trajectories are the only solutions that conserve total left (or right)
probability. In Brandt et al., Phys. Lett. A, 249 (1998) 265--270, they define
quantile motion--unique trajectories are solved by assuming that the total
probability on each side of the particle is conserved. They argue that the
quantile trajectories are identical to the Bohm trajectories. Their argument,
however, fails to notice the gauge freedom in the definition of the quantum
probability current. Our paper sidesteps this under-determinedness of the
probability current. The one-dimensional probability conservation can be used
for higher dimensional problems if the wave function is separable. Several

710.41 | Sub-Kolmogorov-Scale Fluctuations in Fluid Turbulence | We relate the intermittent fluctuations of velocity gradients in turbulence
to a whole range of local dissipation scales generalizing the picture of a
single mean dissipation length. The statistical distribution of these local
dissipation scales as a function of Reynolds number is determined in numerical
simulations of forced homogeneous isotropic turbulence with a spectral
resolution never applied before which exceeds the standard one by at least a
factor of eight. The core of the scale distribution agrees well with a
theoretical prediction. Increasing Reynolds number causes the generation of
ever finer local dissipation scales. This is in line with a less steep decay of
the large-wavenumber energy spectra in the dissipation range. The energy
spectrum for the highest accessible Taylor microscale Reynolds number
R_lambda=107 does not show a bottleneck.

710.4101 | Future Experiments in Relativistic Heavy Ion Collisions | The measurements at RHIC have revealed a new state of matter, which needs to
be further characterized in order to better understand its implications for the
early evolution of the universe and QCD. I will show that, in the near future,
complementary key measurements can be performed at RHIC, LHC, and FAIR. I will
focus on results than can be obtained using identified particles, a probe which
has been the basis for this conference over the past three decades. The
sophisticated detectors, built and planned, for all three accelerator
facilities enable us to measure leptons, photons, muons as well as hadrons and
resonances of all flavors almost equally well, which makes these experiments

710.4102 | Decay of the Maxwell field on the Schwarzschild manifold | We study solutions of the decoupled Maxwell equations in the exterior region
of a Schwarzschild black hole. In stationary regions, where the Schwarzschild
coordinate $r$ ranges over $2M < r_1 < r < r_2$, we obtain a decay rate of
$t^{-1}$ for all components of the Maxwell field. We use vector field methods
and do not require a spherical harmonic decomposition.
In outgoing regions, where the Regge-Wheeler tortoise coordinate is large,
$r_*>\epsilon t$, we obtain decay for the null components with rates of
$|\phi_+| \sim |\alpha| < C r^{-5/2}$, $|\phi_0| \sim |\rho| + |\sigma| < C
r^{-2} |t-r_*|^{-1/2}$, and $|\phi_{-1}| \sim |\underline{\alpha}| < C r^{-1}
|t-r_*|^{-1}$. Along the event horizon and in ingoing regions, where $r_*<0$,
and when $t+r_*1$, all components (normalized with respect to an ingoing null
basis) decay at a rate of $C \uout^{-1}$ with $\uout=t+r_*$ in the exterior
region.

it has a two component structure closely matching the spin excitation spectrum
recently measured by magnetic neutron scattering. We contrast the temperature
evolution of the spectral density and the two-peak behavior in La2-xSrxCuO4
with another high temperature superconductor Bi2Sr2CaCu2O8+d. The bosonic
spectral functions of the two materials account for the low Tc of LSCO as
compared to Bi-2212.

710.4105 | A Note on the Secrecy Capacity of the Multi-antenna Wiretap Channel | Recently, the secrecy capacity of the multi-antenna wiretap channel was
characterized by Khisti and Wornell [1] using a Sato-like argument. This note
presents an alternative characterization using a channel enhancement argument.
This characterization relies on an extremal entropy inequality recently proved
in the context of multi-antenna broadcast channels, and is directly built on
the physical intuition regarding to the optimal transmission strategy in this
communication scenario.

710.4106 | Cash Sub-additive Risk Measures and Interest Rate Ambiguity | A new class of risk measures called cash sub-additive risk measures is
introduced to assess the risk of future financial, nonfinancial and insurance
positions. The debated cash additive axiom is relaxed into the cash sub
additive axiom to preserve the original difference between the numeraire of the
current reserve amounts and future positions. Consequently, cash sub-additive
risk measures can model stochastic and/or ambiguous interest rates or
defaultable contingent claims. Practical examples are presented and in such
contexts cash additive risk measures cannot be used. Several representations of
the cash sub-additive risk measures are provided. The new risk measures are
characterized by penalty functions defined on a set of sub-linear probability
measures and can be represented using penalty functions associated with cash
additive risk measures defined on some extended spaces. The issue of the
optimal risk transfer is studied in the new framework using inf-convolution
techniques. Examples of dynamic cash sub-additive risk measures are provided

710.4109 | Extremal problems on triangle areas in two and three dimensions | The study of extremal problems on triangle areas was initiated in a series of
papers by Erd\H{o}s and Purdy in the early 1970s. In this paper we present new
results on such problems, concerning the number of triangles of the same area
that are spanned by finite point sets in the plane and in 3-space, and the
number of distinct areas determined by the triangles.
In the plane, our main result is an $O(n^{44/19}) =O(n^{2.3158})$ upper bound
on the number of unit-area triangles spanned by $n$ points, which is the first
breakthrough improving the classical bound of $O(n^{7/3})$ from 1992. We also
make progress in a number of important special cases: We show that (i) For
points in convex position, there exist $n$-element point sets that span
$\Omega(n\log n)$ triangles of unit area. (ii) The number of triangles of
minimum (nonzero) area determined by $n$ points is at most ${2/3}(n^2-n)$;
there exist $n$-element point sets (for arbitrarily large $n$) that span
$(6/\pi^2-o(1))n^2$ minimum-area triangles. (iii) The number of acute triangles
of minimum area determined by $n$ points is O(n); this is asymptotically tight.
(iv) For $n$ points in convex position, the number of triangles of minimum area
is O(n); this is asymptotically tight. (v) If no three points are allowed to be
collinear, there are $n$-element point sets that span $\Omega(n\log n)$
minimum-area triangles (in contrast to (ii), where collinearities are allowed
and a quadratic lower bound holds).
In 3-space we prove an $O(n^{17/7}\beta(n))= O(n^{2.4286})$ upper bound on
the number of unit-area triangles spanned by $n$ points, where $\beta(n)$ is an
extremely slowly growing function related to the inverse Ackermann function.
The best previous bound, $O(n^{8/3})$, is an old result from 1971.
| math.CO | the study of extremal problems on triangle areas was initiated in a series of papers by erdhos and purdy in the early 1970s in this paper we present new results on such problems concerning the number of triangles of the same area that are spanned by finite point sets in the plane and in 3space and the number of distinct areas determined by the triangles in the plane our main result is an on4419 on23158 upper bound on the number of unitarea triangles spanned by n points which is the first breakthrough improving the classical bound of on73 from 1992 we also make progress in a number

stationary solutions, we give a lower estimate on the microstates free entropy
dimension of certain $n$-tuples $X_{1},...,X_{n}$: we show that Abstract. By
proving that certain free stochastic differential equations with analytic
coefficients have stationary solutions, we give a lower estimate on the
microstates free entropy dimension of certain n-tuples X_{1},...,X_{n}. In
particular, we show that
\delta_{0}(X_{1},...,X_{n})\geq\dim_{M\bar{\otimes}M^{o}}V where
M=W^{*}(X_{1},...,X_{n}) and
V=\{(\partial(X_{1}),...,\partial(X_{n})):\partial\in\mathcal{C}\} is the set
of values of derivations A=\mathbb{C}[X_{1},... X_{n}]\to A\otimes A with the
property that \partial^{*}\partial(A)\subset A. We show that for q sufficiently
small (depending on n) and X_{1},...,X_{n} a q-semicircular family,
\delta_{0}(X_{1},...,X_{n})>1. In particular, for small q, q-deformed free
group factors have no Cartan subalgebras. An essential tool in our analysis is
a free analog of an inequality between Wasserstein distance and Fisher

710.4112 | A direct Measurement of the W Boson Width in ppbar Collisions at sqrt(s)
= 1.96 TeV | A direct measurement of the total decay width of the W boson G_W is presented
using 350 pb-1 of data from ppbar collisions at sqrt(s) = 1.96 TeV collected
with the CDF II detector at the Fermilab Tevatron. The width is determined by
normalizing predicted signal and background distributions to 230185 W
candidates decaying to enu and munu in the transverse-mass region 50 < M_T < 90
GeV and then fitting the predicted shape to 6055 events in the high-M_T region,
90 < M_T < 200 GeV. The result is G_W = 2032 +/- 45 (stat.) +/- 57 (syst.) MeV,
consistent with the standard model expectation.

710.4113 | On the Chernoff distance for asymptotic LOCC discrimination of bipartite
quantum states | Motivated by the recent discovery of a quantum Chernoff theorem for
asymptotic state discrimination, we investigate the distinguishability of two
bipartite mixed states under the constraint of local operations and classical
communication (LOCC), in the limit of many copies. While for two pure states a
result of Walgate et al. shows that LOCC is just as powerful as global
measurements, data hiding states (DiVincenzo et al.) show that locality can
impose severe restrictions on the distinguishability of even orthogonal states.
Here we determine the optimal error probability and measurement to discriminate
many copies of particular data hiding states (extremal d x d Werner states) by
a linear programming approach. Surprisingly, the single-copy optimal
measurement remains optimal for n copies, in the sense that the best strategy
is measuring each copy separately, followed by a simple classical decision

710.4114 | Breathers in inhomogeneous nonlinear lattices: an analysis via centre
manifold reduction | We consider an infinite chain of particles linearly coupled to their nearest
neighbours and subject to an anharmonic local potential. The chain is assumed
weakly inhomogeneous. We look for small amplitude discrete breathers. The
problem is reformulated as a nonautonomous recurrence in a space of
time-periodic functions, where the dynamics is considered along the discrete
spatial coordinate. We show that small amplitude oscillations are determined by
finite-dimensional nonautonomous mappings, whose dimension depends on the
solutions frequency. We consider the case of two-dimensional reduced mappings,
which occurs for frequencies close to the edges of the phonon band. For an
homogeneous chain, the reduced map is autonomous and reversible, and
bifurcations of reversible homoclinics or heteroclinic solutions are found for
appropriate parameter values. These orbits correspond respectively to discrete
breathers, or dark breathers superposed on a spatially extended standing wave.
Breather existence is shown in some cases for any value of the coupling
constant, which generalizes an existence result obtained by MacKay and Aubry at
small coupling. For an inhomogeneous chain the study of the nonautonomous
reduced map is in general far more involved. For the principal part of the
reduced recurrence, using the assumption of weak inhomogeneity, we show that
homoclinics to 0 exist when the image of the unstable manifold under a linear
transformation intersects the stable manifold. This provides a geometrical
understanding of tangent bifurcations of discrete breathers. The case of a mass
impurity is studied in detail, and our geometrical analysis is successfully
compared with direct numerical simulations.

710.4117 | From the entropy to the statistical structure of spike trains | We use statistical estimates of the entropy rate of spike train data in order
to make inferences about the underlying structure of the spike train itself. We
first examine a number of different parametric and nonparametric estimators
(some known and some new), including the ``plug-in'' method, several versions
of Lempel-Ziv-based compression algorithms, a maximum likelihood estimator
tailored to renewal processes, and the natural estimator derived from the
Context-Tree Weighting method (CTW). The theoretical properties of these
estimators are examined, several new theoretical results are developed, and all
estimators are systematically applied to various types of synthetic data and
under different conditions.
Our main focus is on the performance of these entropy estimators on the
(binary) spike trains of 28 neurons recorded simultaneously for a one-hour
period from the primary motor and dorsal premotor cortices of a monkey. We show
how the entropy estimates can be used to test for the existence of long-term
structure in the data, and we construct a hypothesis test for whether the
renewal process model is appropriate for these spike trains. Further, by
applying the CTW algorithm we derive the maximum a posterior (MAP) tree model
of our empirical data, and comment on the underlying structure it reveals.

710.4118 | Separatrices and basins of stability from time series data | An approach is presented for identifying separatrices in phase space
generated from noisy time series data sets representative of measured
experimental data. These separatrices are identified as ridges in the phase
space distribution of finite-time Lyapunov exponents, i.e., Lagrangian coherent
structures (LCS). As opposed to previous approaches, the LCS is identified
using only trajectories since no analytical or data-defined vector field is
available. The method is applied to a biological simulation in which the
separatrix reveals a basin of stability. These results suggest that the method
will be a fruitful approach to time series analysis, particularly in cases

710.4121 | Charged Higgs-boson production in association with an electron and a
neutrino at electron-positron colliders | We present results of a calculation of the cross section for the production
of a charged Higgs boson in association with an electron and a neutrino at
electron-positron colliders (e+ e- -> H+ e- nu_e-bar, H- e+ nu_e). We study
predictions for the cross section in the Minimal Supersymmetric Standard Model
(MSSM) and the Two Higgs Doublet Model (THDM), highlighting possible
differences. The process is effectively loop-induced in both models. Hence, the
cross section is expected to be strongly model-dependent. Most notably, due to
the presence of superpartners, the MSSM amplitude contains Feynman graphs of
pentagon-type, which are not present in the THDM. This is the first complete
one-loop calculation of the cross section for this process in the THDM and the
MSSM. For both models, so far, only approximate results with limited ranges of
validity were available. Our main aim here is to clarify several open questions
in the existing literature on this process. Specifically, we will discuss the

710.4122 | Discretely guided electromagnetic effective medium | A material comprised of an array of subwavelength coaxial waveguides
decomposes incident electromagnetic waves into spatially discrete wave
components, propagates these components without frequency cut-off, and
reassembles them on the far side of the material. The propagation of these wave
components is fully controlled by the physical properties of the waveguides and
their geometrical distribution in the array. This allows for an exceptional
degree of control over the electromagnetic response of this effective medium,
with numerous potential applications. With the development of nanoscale
subwavelength coaxial waveguides, these applications (including metamaterial
functionality) can be enabled in the visible frequency range.

710.4123 | Towards a Solution for the Ca II Triplet Puzzle : Results from Dwarf
Elliptical Galaxies | We present new estimates of ages and metallicities, based on FORS/VLT optical
(4400-5500A) spectroscopy, of 16 dwarf elliptical galaxies (dE's) in the Fornax
Cluster and in Southern Groups. These dE's are more metal-rich and younger than
previous estimates based on narrow-band photometry and low-resolution
spectroscopy. For our sample we find a mean metallicity [Z/H] = -0.33 dex and
mean age 3.5 Gyr, consistent with similar samples of dE's in other environments
(Local Group, Virgo). Three dE's in our sample show emission lines and very
young ages. This suggests that some dE's formed stars until a very recent epoch
and were self-enriched by a long star formation history. Previous observations
of large near-infrared (~8500A) Ca II absorption strengths in these dE's are in

710.4125 | Quadratic Hierarchy Flavor Rule as the Origin of Dirac CP-Violating
Phases | The premise of an organizing quadratic hierarchy rule in lepton-quark flavor
physics was used earlier for explanation of the hierarchy patterns of four
generic pairs of flavor quantities 1) charged-lepton and 2) neutrino deviations
from mass-degeneracy, 3) deviations of lepton mixing from maximal magnitude and
4) deviations of quark mixing from minimal one. Here it is shown that the
quadratic hierarchy equation that is uniquely related to three flavor particle
generations may have yet another important function. It determines two
complementary values of the Dirac CP-violating phases in the quark and neutrino
mixing matrices without involvement of any empirical parameters. If confirmed
by accurate experimental data, it means a discovery of an explicit CP-violation
source in elementary particle mixing matrices and a single source of
CP-violation at least in the quark mass matrix phenomenology.

low-dimensional Mott-Hubbard insulator TiOBr by transmittance and reflectance
measurements in the infrared and visible frequency range. A suppression of the
transmittance above a critical pressure and a concomitant increase of the
reflectance are observed, suggesting a pressure-induced metallization of TiOBr.
The metallic phase of TiOBr at high pressure is confirmed by the presence of
additional excitations extending down to the far-infrared range. The
pressure-induced metallization coincides with a structural phase transition,
according to the results of x-ray powder diffraction experiments under
pressure.

710.4127 | Gene network reconstruction from transcriptional dynamics under kinetic
model uncertainty: a case for the second derivative | Motivation: Measurements of gene expression over time enable the
reconstruction of transcriptional networks. However, Bayesian networks and many
other current reconstruction methods rely on assumptions that conflict with the
differential equations that describe transcriptional kinetics. Practical
approximations of kinetic models would enable inferring causal relationships
between genes from expression data of microarray, tag-based and conventional
platforms, but conclusions are sensitive to the assumptions made.
Results: The representation of a sufficiently large portion of genome enables
computation of an upper bound on how much confidence one may place in
influences between genes on the basis of expression data. Information about
which genes encode transcription factors is not necessary but may be
incorporated if available. The methodology is generalized to cover cases in
which expression measurements are missing for many of the genes that might
control the transcription of the genes of interest. The assumption that the
gene expression level is roughly proportional to the rate of translation led to
better empirical performance than did either the assumption that the gene
expression level is roughly proportional to the protein level or the Bayesian
model average of both assumptions.

710.4128 | The absolutely continuous spectrum of one-dimensional Schr"odinger
operators | This paper deals with general structural properties of one-dimensional
Schr"odinger operators with some absolutely continuous spectrum. The basic
result says that the omega limit points of the potential under the shift map
are reflectionless on the support of the absolutely continuous part of the
spectral measure. This implies an Oracle Theorem for such potentials and
Denisov-Rakhmanov type theorems.
In the discrete case, for Jacobi operators, these issues were discussed in my
recent paper [19]. The treatment of the continuous case in the present paper
depends on the same basic ideas.
| math.SP math-ph math.MP | this paper deals with general structural properties of onedimensional schrodinger operators with some absolutely continuous spectrum the basic result says that the omega limit points of the potential under the shift map are reflectionless on the support of the absolutely continuous part of the spectral measure this implies an oracle theorem for such potentials and denisovrakhmanov type theorems in the discrete case for jacobi operators these issues were discussed in my recent paper 19 the treatment of the continuous case in the present paper depends on the same basic ideas | [['this', 'paper', 'deals', 'with', 'general', 'structural', 'properties', 'of', 'onedimensional', 'schrodinger', 'operators', 'with', 'some', 'absolutely', 'continuous', 'spectrum', 'the', 'basic', 'result', 'says', 'that', 'the', 'omega', 'limit', 'points', 'of', 'the', 'potential', 'under', 'the', 'shift', 'map', 'are', 'reflectionless', 'on', 'the', 'support', 'of', 'the', 'absolutely', 'continuous', 'part', 'of', 'the', 'spectral', 'measure', 'this', 'implies', 'an', 'oracle', 'theorem', 'for', 'such', 'potentials', 'and', 'denisovrakhmanov', 'type', 'theorems', 'in', 'the', 'discrete', 'case', 'for', 'jacobi', 'operators', 'these', 'issues', 'were', 'discussed', 'in', 'my', 'recent', 'paper', '19', 'the', 'treatment', 'of', 'the', 'continuous', 'case', 'in', 'the', 'present', 'paper', 'depends', 'on', 'the', 'same', 'basic', 'ideas']] | [-0.11101449016067717, 0.08084402717278054, -0.07663725612995526, 0.040398525960174285, -0.05034157628090018, -0.09393777579276098, 0.024897094630998456, 0.343068998058637, -0.26682864491724306, -0.1786093103285465, 0.13473982627943365, -0.29335646564140916, -0.16735035652915636, 0.19109909374965356, -0.14019058346748353, 0.09728538477793336, 0.04837982247376608, 0.06695917263730533, -0.07896642213842521, -0.2227417811440925, 0.4124666829127818, -0.022555405558604334, 0.25002411677916014, 0.07817906930512335, 0.055152520283849704, 0.06369309446050062, -0.0705362351740607, -0.06136048743501306, -0.12933378601228468, 0.1388838218550922, 0.21331819122036297, 0.08457209363372789, 0.2827988775653972, -0.3962975308712986, -0.2037227094069951, 0.1593173521829562, 0.0892241911083046, 0.0313199059180786, -0.04214689350014345, -0.2871424358389858, 0.060478820589681466, -0.11204486065026786, -0.22497030396221412, -0.03450669438267748, 0.010257471958175302, 0.07961539983128509, -0.2431589772265094, 0.09983109720051289, 0.159233885548181, 0.07747455621138215, -0.11928258588434093, -0.10162843516381044, 0.024240348922709622, 0.089860012780668, 0.04387311005137033, 0.012054535389567415, 0.0718123627619611, -0.05220902221173876, -0.11791086270887818, 0.37087988526456883, -0.06356680470829208, -0.1962431485661202, 0.16569861501662267, -0.14872671972649792, -0.20701648987208804, 0.048816883866675195, 0.10848403715321588, 0.13657604998184575, -0.1444360874593258, 0.1793667882829646, -0.06517924546173567, 0.13019376837667854, 0.06412547381801738, 0.07755851264745514, 0.12651539103955858, 0.08187924595032302, 0.10394152190743221, 0.13039416145119404, 0.015101631025835458, -0.09534232761814362, -0.3774875038613876, -0.14611938297748567, -0.16185953816812898, 0.05378993857238028, -0.06414620799203274, -0.1938375619602286, 0.44441206937448846, 0.12282645389334196, 0.19023828544757432, 0.08526704967435864, 0.23616146714193748, 0.19392195279813476, -0.019414323877491473, 0.03371278343515264, 0.20765492861165613, 0.17368393923000744, 0.12788647893661012, -0.15047745281416508, 0.0013524681860063639, 0.1064754462076558] |
710.4129 | Evolution of chemical abundances in Seyfert galaxies | We computed the chemical evolution of spiral bulges hosting Seyfert nuclei,
based on updated chemical and spectro-photometrical evolution models for the
bulge of our Galaxy, made predictions about other quantities measured in
Seyferts, and modeled the photometry of local bulges. The chemical evolution
model contains detailed calculations of the Galactic potential and of the
feedback from the central supermassive black hole, and the spectro-photometric
model covers a wide range of stellar ages and metallicities. We followed the
evolution of bulges in the mass range 10^9 - 10^{11} Msun by scaling the star
formation efficiency and the bulge scalelength as in the inverse-wind scenario
for elliptical galaxies, and considering an Eddington limited accretion onto
the central supermassive black hole. We successfully reproduced the observed
black hole-host bulge mass relation. The observed nuclear bolometric luminosity
is reproduced only at high redshift or for the most massive bulges; in the
other cases, at z = 0 a rejuvenation mechanism is necessary. The black hole
feedback is in most cases not significant in triggering the galactic wind. The
observed high star formation rates and metal overabundances are easily
achieved, as well as the constancy of chemical abundances with redshift and the
bulge present-day colours. Those results are not affected if we vary the index
of the stellar IMF from x=0.95 to x=1.35; a steeper IMF is instead required in
order to reproduce the colour-magnitude relation and the present K-band
luminosity of the bulge.

710.4131 | Numerical Simulations of Oscillating Soliton Stars: Excited States in
Spherical Symmetry and Ground State Evolutions in 3D | Excited state soliton stars are studied numerically for the first time. The
stability of spherically symmetric S-branch excited state oscillatons under
radial perturbations is investigated using a 1D code. We find that these stars
are inherently unstable either migrating to the ground state or collapsing to
black holes. Higher excited state configurations are observed to cascade
through intermediate excited states during their migration to the ground state.
This is similar to excited state boson stars. Ground state oscillatons are then
studied in full 3D numerical relativity. Finding the appropriate gauge
condition for the dynamic oscillatons is much more challenging than in the case
of boson stars. Different slicing conditions are explored, and a customized
gauge condition that approximates polar slicing in spherical symmetry is
implemented. Comparisons with 1D results and convergence tests are performed.
The behavior of these stars under small axisymmetric perturbations is studied
and gravitational waveforms are extracted. We find that the gravitational waves
damp out on a short timescale, enabling us to obtain the complete waveform.
This work is a starting point for the evolution of real scalar field systems
with arbitrary symmetries.

710.4132 | Evidence for Non-Hydrostatic Gas from the Cluster X-ray to Lensing Mass
Ratio | Using a uniform analysis procedure, we measure spatially resolved weak
gravitational lensing and hydrostatic X-ray masses for a sample of 18 clusters
of galaxies. We find a radial trend in the X-ray to lensing mass ratio: at
r2500 we obtain a ratio MX/ML=1.03+/-0.07 which decreases to MX/ML=0.78+/-0.09
at r500. This difference is significant at 3 sigma once we account for
correlations between the measurements. We show that correcting the lensing mass
for excess correlated structure outside the virial radius slightly reduces, but
does not eliminate this trend. An X-ray mass underestimate, perhaps due to
nonthermal pressure support, can explain the residual trend. The trend is not
correlated with the presence or absence of a cool core. We also examine the
cluster gas fraction and find no correlation with ML, an important result for

710.4133 | Lattice calculation of non-Gaussianity from preheating | If light scalar fields are present at the end of inflation, their
non-equilibrium dynamics such as parametric resonance or a phase transition can
produce non-Gaussian density perturbations. We show how these perturbations can
be calculated using non-linear lattice field theory simulations and the
separate universe approximation. In the massless preheating model, we find that
some parameter values are excluded while others lead to acceptable but
observable levels of non-Gaussianity. This shows that preheating can be an
important factor in assessing the viability of inflationary models.

variations | Since 1999, a radial velocity survey of 179 red giant stars is ongoing at
Lick Observatory with a one month cadence. At present ~20-100 measurements have
been collected per star with an accuracy of 5 to 8 m/s. Of the stars monitored,
145 (80%) show radial velocity (RV) variations at a level >20 m/s, of which 43
exhibit significant periodicities. Here, we investigate the mechanism causing
the observed radial velocity variations. Firstly, we search for a correlation
between the radial velocity amplitude and an intrinsic parameter of the star,
in this case surface gravity (log g). Secondly, we investigate line profile
variations and compare these with theoretical predictions.

Survey. IV. The color-magnitude relation | We present an analysis of the optical colors of 413 Virgo cluster early-type
dwarf galaxies (dEs), based on Sloan Digital Sky Survey imaging data. Our study
comprises (1) a comparison of the color-magnitude relation (CMR) of the
different dE subclasses that we identified in Paper III of this series, (2) a
comparison of the shape of the CMR in low and high-density regions, (3) an
analysis of the scatter of the CMR, and (4) an interpretation of the observed
colors with ages and metallicities from population synthesis models. We find
that the CMRs of nucleated (dE(N)) and non-nucleated dEs (dE(nN)) are
significantly different from each other, with similar colors at fainter
magnitudes (r > 17 mag), but increasingly redder colors of the dE(N)s at
brighter magnitudes. We interpret this with older ages and/or higher
metallicities of the brighter dE(N)s. The dEs with disk features have similar
colors as the dE(N)s and seem to be only slightly younger and/or less
metal-rich on average. Furthermore, we find a small but significant dependence
of the CMR on local projected galaxy number density, consistently seen in all
of u-r, g-r, and g-i, and weakly i-z. We deduce that a significant intrinsic
color scatter of the CMR is present, even when allowing for a distance spread
of our galaxies. No increase of the CMR scatter at fainter magnitudes is
observed down to r = 17 mag (Mr = -14 mag). The color residuals, i.e., the
offsets of the data points from the linear fit to the CMR, are clearly
correlated with each other in all colors for the dE(N)s and for the full dE
sample. We conclude that there must be at least two different formation
channels for early-type dwarfs in order to explain the heterogeneity of this
class of galaxy. (Abridged)

710.4136 | Angular Signatures of Annihilating Dark Matter in the Cosmic Gamma-Ray
Background | The extragalactic cosmic gamma-ray background (CGB) is an interesting channel
to look for signatures of dark matter annihilation. In particular, besides the
imprint in the energy spectrum, peculiar anisotropy patterns are expected
compared to the case of a pure astrophysical origin of the CGB. We take into
account the uncertainties in the dark matter clustering properties on
sub-galactic scales, deriving two possible anisotropy scenarios. A clear dark
matter angular signature is achieved when the annihilation signal receives only
a moderate contribution from sub-galactic clumps and/or cuspy haloes.
Experimentally, if galactic foregrounds systematics are efficiently kept under
control, the angular differences are detectable with the forthcoming GLAST
observatory, provided that the annihilation signal contributes to the CGB for a
fraction >10-20%. If, instead, sub-galactic structures have a more prominent
role, the astrophysical and dark matter anisotropies become degenerate,
correspondingly diluting the DM signature. As complementary observables we also
introduce the cross-correlation between surveys of galaxies and the CGB and the
cross-correlation between different energy bands of the CGB and we find that
they provide a further sensitive tool to detect the dark matter angular
signatures.

710.4137 | Can gravitational infall energy lead to the observed velocity dispersion
in DLAs? | The median observed velocity width v_90 of low-ionization species in damped
Ly-alpha systems is close to 90 km/s, with approximately 10% of all systems
showing v_90 > 210 km/s at z=3. We show that a relative shortage of such
high-velocity neutral gas absorbers in state-of-the-art galaxy formation models
is a fundamental problem, present both in grid-based and particle-based
numerical simulations. Using a series of numerical simulations of varying
resolution and box size to cover a wide range of halo masses, we demonstrate
that energy from gravitational infall alone is insufficient to produce the
velocity dispersion observed in damped Ly-alpha systems, nor does this
dispersion arise from an implementation of star formation and feedback in our
highest resolution (~ 45 pc) models, if we do not put any galactic winds into
our models by hand. We argue that these numerical experiments highlight the
need to separate dynamics of different components of the multiphase
interstellar medium at z=3.

710.4138 | Multiwavelength Observations of Markarian 421 in March 2001: an
Unprecedented View on the X-ray/TeV Correlated Variability | (Abridged) We present a detailed analysis of week-long simultaneous
observations of the blazar Mrk421 at 2-60 keV X-rays (RXTE) and TeV gamma-rays
(Whipple and HEGRA) in 2001. The unprecedented quality of this dataset enables
us to establish firmly the existence of the correlation between the TeV and
X-ray luminosities, and to start unveiling some of its more detailed
characteristics, in particular its energy dependence, and time variability. The
source shows strong, highly correlated variations in X-ray and gamma-ray. No
evidence of X-ray/gamma-ray interband lag is found on the full week dataset (<3
ks). However, a detailed analysis of the March 19 flare reveals that data are
not consistent with the peak of the outburst in the 2-4 keV X-ray and TeV band
being simultaneous. We estimate a 2.1+/-0.7 ks TeV lag. The amplitudes of the
X-ray and gamma-ray variations are also highly correlated, and the TeV
luminosity increases more than linearly w.r.t. the X-ray one. The strong
correlation supports the standard model in which a unique electrons population
produces the X-rays by synchrotron radiation and the gamma-ray component by
inverse Compton scattering. However, for the individual best observed flares
the gamma-ray flux scales approximately quadratically w.r.t. the X-ray flux,
posing a serious challenge to emission models for TeV blazars. Rather special
conditions and/or fine tuning of the temporal evolution of the physical
parameters of the emission region are required in order to reproduce the
quadratic correlation.

710.4139 | Are There Four-Dimensional Small Black Rings? | In d>4 dimensions, one can argue for the existence of small black rings using
a scaling argument. We apply the same scaling argument to the d=4 case and
demonstrate that it fails to say anything about the existence of d=4 small
black rings, because stringy corrections get out of control. General relativity
theorems say that there does not exist a black hole with toroidal topology for
d=4, but we interpret this as saying that, for d=4 small black rings, stringy
corrections are crucial which invalidate the assumptions those theorems are
based on.

710.4141 | String Topology: Background and Present State | The data of a "2D field theory with a closed string compactification" is an
equivariant chain level action of a cell decomposition of the union of all
moduli spaces of punctured Riemann surfaces with each component compactified as
a pseudomanifold with boundary. The axioms on the data are contained in the
following assumptions. It is assumed the punctures are labeled and divided into
nonempty sets of inputs and outputs. The inputs are marked by a tangent
direction and the outputs are weighted by nonnegative real numbers adding to
unity. It is assumed the gluing of inputs to outputs lands on the
pseudomanifold boundary of the cell decomposition and the entire pseudomanifold
boundary is decomposed into pieces by all such factorings. It is further
assumed that the action is equivariant with respect to the toroidal action of
rotating the markings. A main result of compactified string topology is the
Theorem (closed strings): Each oriented smooth manifold has a 2D field theory
with a closed string compactification on the equivariant chains of its free
loop space mod constant loops. The sum over all surface types of the top
pseudomanifold chain yields a chain X satisfying the master equation dX + X*X =
0 where * is the sum over all gluings. This structure is well defined up to
homotopy.
The genus zero parts yields an infinity Lie bialgebra on the equivariant
chains of the free loop space mod constant loops. The higher genus terms
provide further elements of algebraic structure called a "quantum Lie
bialgebra" partially resolving the involutive identity.
There is also a compactified discussion and a Theorem 2 for open strings as
the first step to a more complete theory. We note a second step for knots.

710.4142 | Far-Infrared Spectral Energy Distributions and Photometric Redshifts of
Dusty Galaxies | We infer the large-scale source parameters of dusty galaxies from their
observed spectral energy distributions (SEDs) using the analytic radiative
transfer methodology presented in Chakrabarti & McKee (2005). For local
ultra-luminous infrared galaxies (ULIRGs), we show that the millimeter to
far-infrared (FIR) SEDs can be well fit using the standard dust opacity index
of 2 when self-consistent radiative transfer solutions are employed, indicating
that the cold dust in local ULIRGs can be described by a single grain model. We
develop a method for determining photometric redshifts of ULIRGs and sub-mm
galaxies from the millimeter-FIR SED; the resulting value of $1+z$ is typically
accurate to about 10%. As such, it is comparable to the accuracy of near-IR
photometric redshifts and provides a complementary means of deriving redshifts
from far-IR data, such as that from the upcoming $\it{Herschel Space
Observatory}$. Since our analytic radiative transfer solution is developed for
homogeneous, spherically symmetric, centrally heated, dusty sources, it is
relevant for infrared bright galaxies that are primarily powered by compact
sources of luminosity that are embedded in a dusty envelope. We discuss how
deviations from spherical symmetry may affect the applicability of our
solution, and we contrast our self-consistent analytic solution with standard
approximations to demonstrate the main differences.

710.4143 | Lensing and Supernovae: Quantifying The Bias on the Dark Energy Equation
of State | The gravitational magnification and demagnification of Type Ia supernovae
(SNe) modify their positions on the Hubble diagram, shifting the distance
estimates from the underlying luminosity-distance relation. This can introduce
a systematic uncertainty in the dark energy equation of state (EOS) estimated
from SNe, although this systematic is expected to average away for sufficiently
large data sets. Using mock SN samples over the redshift range $0 < z \leq 1.7$
we quantify the lensing bias. We find that the bias on the dark energy EOS is
less than half a percent for large datasets ($\gtrsim$ 2,000 SNe). However, if
highly magnified events (SNe deviating by more than 2.5$\sigma$) are
systematically removed from the analysis, the bias increases to $\sim$ 0.8%.
Given that the EOS parameters measured from such a sample have a 1$\sigma$

vapor. A $4f$ system is adopted for imaging and an atomic vapor cell is placed
over the transform plane. The Fraunhofer diffraction pattern of an object in
the object plane can thus be transformed into atomic Raman coherence according
to the idea of ``light storage''. We investigate how the stored diffraction
pattern evolves under diffusion. Our result indicates, under appropriate
conditions, that an image can be reconstructed with high fidelity. The main
reason for this procedure to work is the fact that diffusion of opposite-phase

710.4145 | Observations of Extrasolar Planets During the non-Cryogenic Spitzer
Space Telescope Mission | Precision infrared photometry from Spitzer has enabled the first direct
studies of light from extrasolar planets, via observations at secondary eclipse
in transiting systems. Current Spitzer results include the first longitudinal
temperature map of an extrasolar planet, and the first spectra of their
atmospheres. Spitzer has also measured a temperature and precise radius for the
first transiting Neptune-sized exoplanet, and is beginning to make precise
transit timing measurements to infer the existence of unseen low mass planets.
The lack of stellar limb darkening in the infrared facilitates precise radius
and transit timing measurements of transiting planets. Warm Spitzer will be
capable of a precise radius measurement for Earth-sized planets transiting
nearby M-dwarfs, thereby constraining their bulk composition. It will continue
to measure thermal emission at secondary eclipse for transiting hot Jupiters,
and be able to distinguish between planets having broad band emission versus
absorption spectra. It will also be able to measure the orbital phase variation
of thermal emission for close-in planets, even non-transiting planets, and
these measurements will be of special interest for planets in eccentric orbits.
Warm Spitzer will be a significant complement to Kepler, particularly as
regards transit timing in the Kepler field. In addition to studying close-in
planets, Warm Spitzer will have significant application in sensitive imaging
searches for young planets at relatively large angular separations from their
parent stars.

710.4146 | A Model for Star Formation, Gas Flows and Chemical Evolution in Galaxies
at High Redshifts | Motivated by the increasing use of the Kennicutt-Schmidt (K-S) star formation
law to interpret observations of high redshift galaxies, the importance of gas
accretion to galaxy formation, and the recent observations of chemical
abundances in galaxies at z~2-3, I use simple analytical models to assess the
consistency of these processes of galaxy evolution with observations and with
each other. I derive the time dependence of star formation implied by the K-S
law, and show that the sustained high star formation rates observed in galaxies
at z~2-3 require the accretion of additional gas. A model in which the gas
accretion rate is approximately equal to the combined star formation and
outflow rates broadly reproduces the observed trends of star formation rate
with galaxy age. Using an analytical description of chemical evolution, I also
show that this model, further constrained to have an outflow rate roughly equal
to the star formation rate, reproduces the observed mass-metallicity relation
at z~2.

710.4148 | The MSSM golden region and its collider signature | The "golden region'' in the MSSM parameter space is the region where the
experimental constraints are satisfied and the amount of fine-tuning is
minimized. In this region, the stop trilinear soft term is large, leading to a
significant mass splitting between the two stop mass eigenstates. As a result,
the decay of the heavier stop into the lighter stop and a Z boson is
kinematically allowed throughout the golden region. We propose that the
experiments at the Large Hadron Collider (LHC) can search for this decay
through an inclusive signature, Z+2jb+missing Et+X. We evaluate the Standard
Model backgrounds for this channel, and identify a set of cuts that would allow

that there is a unique biologically relevant solution. That is, we show there
is a unique rational tangle solution, which is also the unique solution with

710.4151 | Dark energy: a quantum fossil from the inflationary Universe? | The discovery of dark energy (DE) as the physical cause for the accelerated
expansion of the Universe is the most remarkable experimental finding of modern
cosmology. However, it leads to insurmountable theoretical difficulties from
the point of view of fundamental physics. Inflation, on the other hand,
constitutes another crucial ingredient, which seems necessary to solve other
cosmological conundrums and provides the primeval quantum seeds for structure
formation. One may wonder if there is any deep relationship between these two
paradigms. In this work, we suggest that the existence of the DE in the present
Universe could be linked to the quantum field theoretical mechanism that may
have triggered primordial inflation in the early Universe. This mechanism,
based on quantum conformal symmetry, induces a logarithmic,
asymptotically-free, running of the gravitational coupling. If this evolution
persists in the present Universe, and if matter is conserved, the general
covariance of Einstein's equations demands the existence of dynamical DE in the
form of a running cosmological term whose variation follows a power law of the
redshift.

710.4152 | Unsigned state models for the Jones polynomial | It is well a known and fundamental result that the Jones polynomial can be
expressed as Potts and vertex partition functions of signed plane graphs. Here
we consider constructions of the Jones polynomial as state models of unsigned
graphs and show that the Jones polynomial of any link can be expressed as a
vertex model of an unsigned embedded graph.
In the process of deriving this result, we show that for every diagram of a
link in the 3-sphere there exists a diagram of an alternating link in a
thickened surface (and an alternating virtual link) with the same Kauffman
bracket. We also recover two recent results in the literature relating the
Jones and Bollobas-Riordan polynomials and show they arise from two different
interpretations of the same embedded graph.
