710.2853 | Exotic hadrons and SU(3) chiral dynamics | We explore a possibility to generate exotic hadrons dynamically in the
scattering of hadrons. The s-wave scattering amplitude of an arbitrary hadron
with the Nambu-Goldstone boson is constructed so as to satisfy the unitarity
condition and the chiral low energy theorem. We find that the chiral
interaction for the exotic channels is in most cases repulsive, and that the
strength of the possible attractive interaction is uniquely determined. We show
that the attractive interaction in exotic channels is not strong enough to
generate a bound state, while the interaction in nonexotic channel generate
bound states which are considered to be the origin of some resonances observed
in nature.

710.2855 | Comparison between 2-D and 3-D codes in dynamical simulations of gas
flow in barred galaxies | Context: One of the ways to determine the contribution of the dark halo to
the gravitational potential of a galaxy is the study of non-circular
(streaming) motions and the associated gas shocks in the bar region. These
motions, determined by the potential in the inner parts, can break the
disk-halo degeneracy. Here, two main fluid dynamical approaches have been
chosen to model the non-circular motions in the bar region; a 2-D Eulerian grid
code for an isothermal gas (FS2) and a 3-D smoothed particle hydrodynamic code
(N-body/SPH). Aims: The aim of this paper is to compare and quantify the
differences of the gas flows in rotating barred potential obtained using two
different fluid dynamical approaches. We analyse the effect of using 2-D and a
3-D codes in the calculation of gas flow in barred galaxies and to which extend
the results are affected by the code. To do this, we derive the velocity field
and density maps for the mass model of NGC 4123 using a 3-D N-body/SPH code and
compare the results to the previous 2-D Eulerian grid code results. Methods:
Numerical modelling, 3-D N-body/SPH simulations Results: The global velocity
field and the gas distribution is very similar in both models. The study shows
that the position and strength of the shocks developed in the SPH simulations
do not vary significantly compared to the results derived from the 2-D FS2
code. The largest velocity difference across the shock is 20\kms between the
2-D and 3-D fluid dynamical models. Conclusions: The results obtained in the
studies deriving the dark matter content of barred galaxies using the bar
streaming motions and strength and position of shocks are robust to the fluid
dynamical model used. The effect of 2-D and 3-D modelling can be neglected in
this type of studies.

710.2856 | An asymptotic integral representation for Carleman orthogonal
polynomials | In this paper we investigate the asymptotic behavior of polynomials that are
orthonormal over the interior domain of an analytic Jordan curve L with respect
to area measure. We prove that, inside L, these polynomials behave
asymptotically like a sequence of certain integrals involving the canonical
conformal map of the exterior of L onto the exterior of the unit circle and
certain meromorphic kernel function defined in terms of a conformal map of the
interior of L onto the unit disk. The error term in the integral representation
is proven to decay geometrically and sufficiently fast, allowing us to obtain
more precise asymptotic formulas for the polynomials under certain additional
geometric considerations. These formulas yield, in turn, fine results on the
location, limiting distribution and accumulation points of the zeros of the
polynomials.

710.2858 | Observation of an unexpected hardening in the spectrum of GRB 021206 | GRB 021206 is one of the brightest GRBs ever observed. Its prompt emission,
as measured by RHESSI, shows an unexpected spectral feature. The spectrum has a
peak energy of about 700 keV and can be described by a Band function up to 4.5
MeV. Above 4.5 MeV, the spectrum hardens again, so that the Band function fails
to fit the whole RHESSI energy range up to 17 MeV. Nor does the sum of a
blackbody function plus a power law, even though such a function can describe a
spectral hardening. The cannonball model on the other hand predicts such a
hardening, and we found that it fits the spectrum of GRB 021206 perfectly. We
also analysed other strong GRBs observed by RHESSI, namely GRBs 020715, 021008,

710.2859 | Nonequilibrium valley polarization in graphene nanoconstrictions | We recently shown, using tight-binding calculations, that nonequilibrium
valley polarization can be realized in graphene, when the current is injected
through "valley filter": a ballistic point contact with zigzag edges. Here we
demonstrate, that the effect is surprisingly robust against changing the
crystallographic orientation of the filter axis. Namely, the output current
remains polarized unless a point contact has perfect armchair edges, at which
two subblattices are equally represented. The polarization is inverted when the
filter orientation crosses the amchair line and, subsequently, dominating
subblattice index of terminal atoms changes. In a bended graphene strip, the
valley-polarized current can be directed towards one edge providing a
theoretical possibility to observe a zero-magnetic-field analogue of the
well-known Hall effect. For the valley valve, build of two valley filters in
series and controlled elecrostatically by a gate voltage, the
conductance-to-gate characteristic is inverted when $\pi/3$ vertex is placed
between two filters.

710.286 | Universal derived equivalences of posets of cluster tilting objects | We show that for two quivers without oriented cycles related by a BGP
reflection, the posets of their cluster tilting objects are related by a simple
combinatorial construction, which we call a flip-flop.
We deduce that the posets of cluster tilting objects of derived equivalent
path algebras of quivers without oriented cycles are universally derived

710.2863 | First quenched results for the matrix elements of the B_{B_s} mixing
parameter in the static limit from tmQCD | We report on a non-perturbative study of the scale-dependent renormalization
factors of a multiplicatively renormalizable basis of Delta B=2 parity-odd
four-fermion operators in quenched lattice QCD. We also present some
preliminary results of the matrix elements related to the mixing parameter of
the B_s-meson. In our lattice formulation, the heavy quark is treated in the
static approximation, while the strange one belongs to a doublet of twisted
mass fermions at full twist, i.e. with twist angle alpha=pi/2. In this
framework, the parity-even Delta B=2 four-fermion operators responsible for the
mixing are rotated onto a linear combination of parity-odd operators in the
above-mentioned basis. Their physical matrix elements between static B_s-mesons
are extracted from lattice correlators with Schroedinger functional boundary

novel technique, L-band angular differential imaging. Our first survey targeted
21 young stars in the Beta Pic and Tuc-Hor moving groups with VLT/NACO reaching
typical sensitivities of <1 MJup at r > 20 AU. The statistical analysis of the
null result demonstrates that the giant planet population is truncated at 30 AU
or less (90% confidence level). Our second, on-going MMT/Clio survey utilizes
the unique sensitivity achieved in the L-band for old planets to probe all
M-dwarf stars within 6 pc. The proximity of these targets enables direct
imaging of planets in orbits like Jupiter for the first time - a key step for
directly imaging giant planets.

wells | In semiconductors with inversion asymmetry, spin-orbit coupling gives rise to
the well-known Dresselhaus and Rashba effects. If one considers quantum wells
with two or more conduction subbands, an additional, intersubband-induced
spin-orbit term appears whose strength is comparable to the Rashba coupling,

band spin splitting due to this intersubband spin-orbit coupling term is
negligible for typical III-V quantum wells.

710.2867 | QED in arbitrary linear media: amplifying media | Recently, we have developed a unified approach to QED in arbitrary linearly
responding media in equilibrium--media that give rise to absorption [Phys. Rev.
A \textbf{75}, (2007) 053813]. In the present paper we show that, under
appropriate conditions, the theory can be quite naturally generalized to
amplifying media the effect of which is described within the framework of
linear response theory. We discuss the limits of validity of the generalized
theory and make contact with earlier quantization schemes suggested for the
case of linearly and locally responding amplifying dielectric-type media. To
illustrate the theory, we present the electromagnetic-field correlation
functions that determine the Casimir force in the presence of amplifying media.

qubits as a generalization of the bipartite case. These pure states have a
bipartite entanglement that does not depend on the bipartition and is maximal

710.2869 | Canonical extensions of local systems | A local system H on a complex manifold M can be viewed in two ways--either as
a locally free sheaf, or as a union of covering spaces T = T(H). When M is an
open set in a bigger manifold, the local system will generally not extend,
because of local monodromy. This paper proposes an extension of the local
system as an analytic space, in the case when the complement of M has normal
crossing singularities, and the local system is unipotent along the boundary
divisor. The analytic space is obtained by taking the closure of T inside the
total space of Deligne's canonical extension of the associated vector bundle.
It is not normal, but its normalization is locally toric.

710.2871 | High-Efficiency Resonant RF Spin Rotator with Broad Phase Space
Acceptance for Pulsed Polarized Cold Neutron Beams | We have developed a radio-frequency resonant spin rotator to reverse the
neutron polarization in a 9.5 cm x 9.5 cm pulsed cold neutron beam with high
efficiency over a broad cold neutron energy range. The effect of the spin
reversal by the rotator on the neutron beam phase space is compared
qualitatively to RF neutron spin flippers based on adiabatic fast passage. The
spin rotator does not change the kinetic energy of the neutrons and leaves the
neutron beam phase space unchanged to high precision. We discuss the design of
the spin rotator and describe two types of transmission-based neutron spin-flip
efficiency measurements where the neutron beam was both polarized and analyzed
by optically-polarized 3He neutron spin filters. The efficiency of the spin
rotator was measured to be 98.0+/-0.8% on resonance for neutron energies from
3.3 to 18.4 meV over the full phase space of the beam. As an example of the
application of this device to an experiment we describe the integration of the
RF spin rotator into an apparatus to search for the small parity-violating
asymmetry A_gamma in polarized cold neutron capture on para-hydrogen by the
NPDGamma collaboration at LANSCE.

710.2872 | Geometrical constraints on dark energy models | This contribution intends to give a pedagogical introduction to the topic of
dark energy (the mysterious agent supposed to drive the observed late time
acceleration of the Universe) and to various observational tests which require
only assumptions on the geometry of the Universe. Those tests are the
supernovae luminosity, the CMB shift, the direct Hubble data, and the baryon
acoustic oscillations test. An historical overview of Cosmology is followed by
some generalities on FRW spacetimes (the best large-scale description of the
Universe), and then the test themselves are discussed. A convenient section on
statistical inference is included as well.

710.2873 | Sensitive multiplex spectroscopy in the molecular fingerprint 2.4 $\mu$m
region with a Cr^{2+}:ZnSe femtosecond laser | An ultrashort-pulse Cr^{2+}:ZnSe laser is a novel broadband source for
sensitive high resolution molecular spectroscopy. A 130-fs pulse allows
covering of up to 380 cm^-1 spectral domain around 2.4 $\mu$m which is analyzed
simultaneously with a 0.12 cm^-1 (3.6 GHz) resolution by a Fourier-transform
spectrometer. Recorded in 13 s, from 70-cm length absorption around 4150 cm^-1,
acetylene and ammonia spectra exhibit a 3800 signal-to-noise ratio and a
2.4*10^-7 cm^-1*Hz^-1/2 noise equivalent absorption coefficient at one second
averaging per spectral element, suggesting a 0.2 ppbv detection level for HF

710.2876 | Information, Inflation, and Interest | We propose a class of discrete-time stochastic models for the pricing of
inflation-linked assets. The paper begins with an axiomatic scheme for asset
pricing and interest rate theory in a discrete-time setting. The first axiom
introduces a "risk-free" asset, and the second axiom determines the
intertemporal pricing relations that hold for dividend-paying assets. The
nominal and real pricing kernels, in terms of which the price index can be
expressed, are then modelled by introducing a Sidrauski-type utility function
depending on (a) the aggregate rate of consumption, and (b) the aggregate rate
of real liquidity benefit conferred by the money supply. Consumption and money
supply policies are chosen such that the expected joint utility obtained over a
specified time horizon is maximised subject to a budget constraint that takes
into account the "value" of the liquidity benefit associated with the money
supply. For any choice of the bivariate utility function, the resulting model
determines a relation between the rate of consumption, the price level, and the
money supply. The model also produces explicit expressions for the real and
nominal pricing kernels, and hence establishes a basis for the valuation of
inflation-linked securities.
| q-fin.GN math.PR | we propose a class of discretetime stochastic models for the pricing of inflationlinked assets the paper begins with an axiomatic scheme for asset pricing and interest rate theory in a discretetime setting the first axiom introduces a riskfree asset and the second axiom determines the intertemporal pricing relations that hold for dividendpaying assets the nominal and real pricing kernels in terms of which the price index can be expressed are then modelled by introducing a sidrauskitype utility function depending on a the aggregate rate of consumption and b the aggregate rate of real liquidity benefit conferred by the money supply consumption and money supply policies are chosen such that the expected joint utility obtained over a specified time horizon is maximised subject to a budget constraint that takes into account the value of the liquidity benefit associated with the money supply for any choice of the bivariate utility function the resulting model determines a relation between the rate of consumption the price level and the money supply the model also produces explicit expressions for the real and nominal pricing kernels and hence

710.2877 | Differential isospin-fractionation in dilute asymmetric nuclear matter | The differential isospin-fractionation (IsoF) during the liquid-gas phase
transition in dilute asymmetric nuclear matter is studied as a function of
nucleon momentum. Within a self-consistent thermal model it is shown that the
neutron/proton ratio of the gas phase becomes {\it smaller} than that of the
liquid phase for energetic nucleons, although the gas phase is overall more
neutron-rich. Clear indications of the differential IsoF consistent with the
thermal model predictions are demonstrated within a transport model for
heavy-ion reactions. Future comparisons with experimental data will allow us to
extract critical information about the momentum dependence of the isovector
strong interaction.

710.2878 | Hydrogen Adsorption of Back Side of Graphene | We studied the interaction between a single hydrogen atom and a single
graphene using classical molecular dynamics simulation with modified Brenner
REBO potential. Three interactions, which are adsorption, reflection,
penetration, were observed. Overhang structure appears and creates an
adsorption site on the backside of the graphene. It is considered that backside
adsorption occurs under the two conditions that an incident hydrogen atom
should have incident energy which is larger than the potential barrier of a
hexagonal hole of the graphene and that after the hydrogen atom passes through
the graphene, it does not keep its kinetic energy to be trapped by the
adsorption site. The conditions explained that as the incident energy
increased, the incident point of the backside adsorption shifted to the
periphery of a hexagonal hole of the graphene in the simulation. Moreover, when

710.2879 | The Richness and Beauty of the Physics of Cosmological Recombination | The physical ingredients to describe the epoch of cosmological recombination
are amazingly simple and well-understood. This fact allows us to take into
account a very large variety of processes, still finding potentially measurable
consequences. In this contribution we highlight some of the detailed physics
that were recently studied in connection with cosmological hydrogen
recombination. The impact of these considerations is two-fold: (i) the
associated release of photons during this epoch leads to interesting and unique
deviations of the Cosmic Microwave Background (CMB) energy spectrum from a
perfect blackbody, which, in particular at decimeter wavelength, may become
observable in the near future. Observing these distortions, in principle would
provide an additional way to determine some of the key parameters of the
Universe (e.g. the specific entropy, the CMB monopole temperature and the
pre-stellar abundance of helium), not suffering from limitations set by cosmic
variance. Also it permits us to confront our detailed understanding of the
recombination process with direct observational evidence. In this contribution
we illustrate how the theoretical spectral template for the cosmological
recombination spectrum may be utilized for this purpose. (ii) with the advent
of high precision CMB data, e.g. as will be available using the Planck Surveyor
or Cmbpol, a very accurate theoretical understanding of the ionization history
of the Universe becomes necessary for the interpretation of the CMB temperature
and polarization anisotropies. (abridged)

QCD | We report on the advances in our unquenched calculation of the matrix
elements relevant for the analysis of B^0-\bar B^0 mixing using the Asqtad
(light quark) and Fermilab (heavy quark) actions. We have calculated the
hadronic parameters for the mass and width differences in the neutral B meson

710.2882 | The Initial Mass Function of the Massive Star-forming Region NGC 3603
from Near-Infrared Adaptive Optics observations | We study the initial mass function (IMF) of one of the most massive Galactic
star-forming regions NGC 3603 to answer a fundamental question in current
astrophysics: is the IMF universal, or does it vary? Using our very deep, high
angular resolution JHKsL' images obtained with NAOS-CONICA at the VLT at ESO,
we have successfully revealed the stellar population down to the subsolar mass
range in the core of the starburst cluster. The derived IMF of NGC 3603 is
reasonably fitted by a single power law with index Gamma ~ -0.74 within a mass
range of 0.4 - 20 Msun, substantially flatter than the Salpeter-like IMF. A
strong radial steepening of the IMF is observed mainly in the inner r < 30''
field, indicating mass segregation in the cluster center. We estimate the total
mass of NGC 3603 to be about 1.0 - 1.6 x 10^4 Msun. The derived core density is
> 6 x 10^4 Msun pc^-3, an order of magnitude larger than e.g., the Orion Nebula
Cluster. The estimate of the half-mass relaxation time for solar-mass stars is
about 10 - 40 Myr, suggesting that the intermediate- and low-mass stars have
not yet been affected significantly by the dynamical relaxation in the cluster.
The relaxation time for the high-mass stars can be comparable to the age of the
cluster. We estimate that the stars residing outside the observed field cannot
steepen the IMF significantly, indicating our IMF adequately describes the
whole cluster. Analyzing thoroughly the systematic uncertainties in our IMF
determination, we conclude that the power law index of the IMF of NGC 3603 is
Gamma = -0.74^{+0.62}_{-0.47}. Our result thus supports the hypothesis of a
potential top-heavy IMF in massive star-forming clusters and starbursts.

to bring researchers and practitioners both from academia and industry
together, with a spirit of openness, to try and identify and begin to address
the numerous and very varied issues of optimization. This succeeded, as can be
seen from the papers, the attendance and the liveliness of the discussions that
took place during and after the workshop, not to mention a few new cooperations
or postdoctoral contracts. The 22 talented people from different groups who
participated were unanimous to appreciate this first edition and recommend that
ICOOOLPS be continued next year. A community is thus beginning to form, and
should be reinforced by a second edition next year, with all the improvements
this first edition made emerge.

710.2888 | Pair-distribution functions of two-temperature two-mass systems:
Comparison of MD, HNC, CHNC, QMC and Kohn-Sham calculations for dense
hydrogen | Two-temperature, two-mass quasi-equilibrium plasmas may occur in electron-ion
plasmas,nuclear-matter, as well as in electron-hole condensed-matter systems.
Dense two-temperature hydrogen plasmas straddle the difficult partially -
degenerate regime of electron densities and temperatures which are important in
astrophysics, in inertial-confinement fusion research, and other areas of warm
dense matter physics. Results from Kohn-Sham calculations and QMC are used to
benchmark the procedures used in classical molecular-dynamics simulations, HNC
and CHNC methods to derive electron-electron and electron-proton pair -
distribution functions. Then, nonequilibrium molecular dynamics for two
-temperature, two-mass plasmas are used to obtain the pair distribution. Using
these results, the correct HNC and CHNC procedures for the evaluation of
pair-distribution functions in two-temperature two-mass two-component charged
fluids are established. Results for a mass ratio of 1:5, typical of

710.2889 | An efficient reduction of ranking to classification | This paper describes an efficient reduction of the learning problem of
ranking to binary classification. The reduction guarantees an average pairwise
misranking regret of at most that of the binary classifier regret, improving a
recent result of Balcan et al which only guarantees a factor of 2. Moreover,
our reduction applies to a broader class of ranking loss functions, admits a
simpler proof, and the expected running time complexity of our algorithm in
terms of number of calls to a classifier or preference function is improved
from $\Omega(n^2)$ to $O(n \log n)$. In addition, when the top $k$ ranked
elements only are required ($k \ll n$), as in many applications in information
extraction or search engines, the time complexity of our algorithm can be
further reduced to $O(k \log k + n)$. Our reduction and algorithm are thus
practical for realistic applications where the number of points to rank exceeds
several thousands. Much of our results also extend beyond the bipartite case
previously studied.
Our rediction is a randomized one. To complement our result, we also derive
lower bounds on any deterministic reduction from binary (preference)
classification to ranking, implying that our use of a randomized reduction is
essentially necessary for the guarantees we provide.

710.289 | Model for a collimated spin wave beam generated by a single layer, spin
torque nanocontact | A model of spin torque induced magnetization dynamics based upon
semi-classical spin diffusion theory for a single layer nanocontact is
presented. The model incorporates effects due to the current induced Oersted
field and predicts the generation of a variety of spatially dependent,
coherent, precessional magnetic wave structures. Directionally controllable
collimated spin wave beams, vortex spiral waves, and localized standing waves
are found to be excited by the interplay of the Oersted field and the
orientation of an applied field. These fields act as a spin wave ``corral''

710.2892 | On the Diversity of the Taurus Transitional Disks: UX Tau A & Lk Ca 15 | The recently recognized class of "transitional disk" systems consists of
young starswith optically-thick outer disks but inner disks which are mostly
devoid of small dust. Here we introduce a further class of "pre-transitional
disks" with significant near-infrared excesses which indicate the presence of
an optically thick inner disk separated from an optically thick outer disk;
thus, the spectral energy distributions of pre-transitional disks suggest the
incipient development of disk gaps rather than inner holes. In UX Tau A, our
analysis of the Spitzer IRS spectrum finds that the near-infrared excess is
produced by an inner optically thick disk and a gap of ~56 AU is present. The
Spitzer IRS spectrum of LkCa 15 is suggestive of a gap of ~46 AU, confirming
previous millimeter imaging. In addition, UX Tau A contains crystalline
silicates in its disk at radii >~ 56 AU which poses a challenge to our
understanding of the production of this crystalline material. In contrast, LkCa
15's silicates are amorphous and pristine. UX Tau A and LkCa 15 increase our
knowledge of the diversity of dust clearing in low-mass star formation.

710.2895 | Quaternionic Analysis and the Algebrodynamics | We present the ``algebrodynamical'' approach to field-particle theory based
on a nonlinear generalization of the Cauchy-Riemann conditions to
non-commutative algebras of quaternion-like type. For complex quaternions the
theory is Lorentz invariant and naturally carries some gauge and twistor
structures. Point- and string-like singularities are considered as
particle-like formations; their electric charge is ``self-quantized''. A novel
``causal Minkowski geometry with additional phase'' is presented that is
induced by the structure of primordial biquaternion algebra. On this
geometrical background a self-consistent algebraic dynamics of singularities
(``ensemble of dublicons'') is briefly discussed.

710.2896 | EasyNData: A simple tool to extract numerical values from published

occurring task. In this article I present a short computer program written in
Java(TM) helping in those cases where someone wants to get the numbers out of a
plot but is not able to read the plot with a decent accuracy and cannot contact
the author of the plot directly for whatever reason. The accuracy reached by

710.2897 | Searches for Squarks and Gluinos with D0 Detector | Searches for supersymmetry in the framework of R-parity conserving models
have been performed in data collected by the D0 detector at the Tevatron
$p\bar{p}$ collider at a center-of-mass energy of 1.96 TeV. Topologies analyzed
consist of acoplanar-jets, multijets, and leptons with large missing transverse
energy in the final state. The 1 fb$^{-1}$ data shows good agreement with the
standard model expectations. The improved mass limits at 95% CL have been
derived. In the first search, generic squarks and gluinos productions are
investigated and lower limits of 375 GeV and 289 GeV are derived on the squarks
and gluino masses, respectively, with $\tan$($\beta$) = 3, $A_0$ = 0 and $\mu
<$ 0. In second analysis, squarks are searched for in a final state that has
$\tau$ leptons accompanied by jets and missing transverse energy. This channel
is explored for the first time at the Tevatron and excludes squark masses $<$
366 GeV. Supergravity inspired models suggest the existence of light
supersymmetric partners of the third generation quarks: a light stop for
moderate values of $\tan(\beta)$, a light sbottom for large $\tan(\beta)$. If
stop is the next-to-lightest supersymmetric particle, the expected decay
channel is $\tilde{t} \to c \tilde{\chi}^0_1$ with $\tilde{\chi}^0_1$ assumed
to be the lightest supersymmetric particle. Using this channel, stop masses $<$
149 GeV and neutralino masses $<$ 63 GeV are excluded. If there is a mass
hierarchy between stop, chargino and sneutrino masses, stop is expected to
decay via $\tilde{t} \to b l \tilde{\nu}$ where $l$ could be an electron or
muon. The search performed with both electrons, muons and dimuon final states
excludes stop mass $<$ 186 GeV for sneutrino mass of 71 GeV.

710.2898 | Higher rank numerical ranges and low rank perturbations of quantum
channels | For a positive integer $k$, the rank-$k$ numerical range $\Lambda_k(A)$ of an
operator $A$ acting on a Hilbert space $\cH$ of dimension at least $k$ is the
set of scalars $\lambda$ such that $PAP = \lambda P$ for some rank $k$
orthogonal projection $P$. In this paper, a close connection between low rank
perturbation of an operator $A$ and $\Lambda_k(A)$ is established. In
particular, for $1 \le r < k$ it is shown that $\Lambda_k(A) \subseteq
\Lambda_{k-r}(A+F)$ for any operator $F$ with $\rank (F) \le r$. In quantum
computing, this result implies that a quantum channel with a $k$-dimensional
error correcting code under a perturbation of rank $\le r$ will still have a
$(k-r)$-dimensional error correcting code. Moreover, it is shown that if $A$ is
normal or if the dimension of $A$ is finite, then $\Lambda_k(A)$ can be
obtained as the intersection of $\Lambda_{k-r}(A+F)$ for a collection of rank
$r$ operators $F$. Examples are given to show that the result fails if $A$ is a
general operator. The closure and the interior of the convex set $\Lambda_k(A)$
are completely determined. Analogous results are obtained for
$\Lambda_\infty(A)$ defined as the set of scalars $\lambda$ such that $PAP =
\lambda P$ for an infinite rank orthogonal projection $P$. It is shown that
$\Lambda_\infty(A)$ is the intersection of all $\Lambda_k(A)$ for $k = 1, 2,
>...$. If $A - \mu I$ is not compact for any $\mu \in \IC$, then the closure
and the interior of $\Lambda_\infty(A)$ coincide with those of the essential
numerical range of $A$. The situation for the special case when $A-\mu I$ is
compact for some $\mu \in \IC$ is also studied.

710.2899 | Discovery of 21cm absorption in a $z_{\rm abs} =2.289$ DLA towards TXS
0311+430: The first low spin temperature absorber at z > 1 | We report the detection of HI 21 cm absorption from the $z=2.289$ damped
Lyman-$\alpha$ system (DLA) towards TXS 0311+430, with the Green Bank
Telescope. The 21 cm absorption has a velocity spread (between nulls) of $\sim
110$ km s$^{-1}$ and an integrated optical depth of $\int \tau {\rm d}V =
(0.818 \pm 0.085)$ km s$^{-1}$. We also present new Giant Metrewave Radio
Telescope 602 MHz imaging of the radio continuum. TXS 0311+430 is unresolved at
this frequency, indicating that the covering factor of the DLA is likely to be
high. Combining the integrated optical depth with the DLA HI column density of
\nhi = $(2 \pm 0.5) \times 10^{20}$ \cm, yields a spin temperature of $T_s =
(138 \pm 36)$ K, assuming a covering factor of unity. This is the first case of
a low spin temperature ($< 350$ K) in a $z > 1$ DLA and is among the lowest
ever measured in any DLA. Indeed, the $T_s$ measured for this DLA is similar to
values measured in the Milky Way and local disk galaxies. We also determine a
lower limit (Si/H) $\gtrsim 1/3$ solar for the DLA metallicity, amongst the
highest abundances measured in DLAs at any redshift. Based on low redshift
correlations, the low $T_s$, large 21 cm absorption width and high metallicity
all suggest that the $z \sim 2.289$ DLA is likely to arise in a massive,
luminous disk galaxy.

710.29 | In Search of Possible Associations between Planetary Nebulae and Open
Clusters | We consider the possibility of cluster membership for 13 planetary nebulae
that are located in close proximity to open clusters lying in their lines of
sight. The short lifetimes and low sample size of intermediate-mass planetary
nebulae with respect to nearby open clusters conspire to reduce the probability
of observing a true association. Not surprisingly, line of sight coincidences
almost certainly exist for 7 of the 13 cases considered. Additional studies are
advocated, however, for 6 planetary nebula/open cluster coincidences in which a
physical association is not excluded by the available evidence, namely M
1-80/Berkeley 57, NGC 2438/NGC 2437, NGC 2452/NGC 2453, VBRC 2 & NGC 2899/IC
2488, and HeFa 1/NGC 6067. A number of additional potential associations
between planetary nebulae and open clusters is tabulated for reference
purposes. It is noteworthy that the strongest cases involve planetary nebulae

710.2901 | Bulges versus disks: the evolution of angular momentum in cosmological
simulations of galaxy formation | We investigate the evolution of angular momentum in simulations of galaxy
formation in a cold dark matter universe. We analyse two model galaxies
generated in the N-body/hydrodynamic simulations of Okamoto et al. Starting
from identical initial conditions, but using different assumptions for the
baryonic physics, one of the simulations produced a bulge-dominated galaxy and
the other one a disc-dominated galaxy. The main difference is the treatment of
star formation and feedback, both of which were designed to be more efficient
in the disc-dominated object. We find that the specific angular momentum of the
disc-dominated galaxy tracks the evolution of the angular momentum of the dark
matter halo very closely: the angular momentum grows as predicted by linear
theory until the epoch of maximum expansion and remains constant thereafter. By
contrast, the evolution of the angular momentum of the bulge-dominated galaxy
resembles that of the central, most bound halo material: it also grows at first
according to linear theory, but 90% of it is rapidly lost as pre-galactic
fragments, into which gas had cooled efficiently, merge, transferring their
orbital angular momentum to the outer halo by tidal effects. The disc-dominated
galaxy avoids this fate because the strong feedback reheats the gas which
accumulates in an extended hot reservoir and only begins to cool once the
merging activity has subsided. Our analysis lends strong support to the
classical theory of disc formation whereby tidally torqued gas is accreted into
the centre of the halo conserving its angular momentum.

710.2902 | A Half-Megasecond Chandra Observation of the Oxygen-Rich Supernova
Remnant G292.0+1.8 | We report on our initial analysis of a deep 510 ks observation of the
Galactic oxygen-rich supernova remnant (SNR) G292.0+1.8 with the {\it Chandra
X-ray Observatory}. Our new {\it Chandra} ACIS-I observation has a larger field
of view and an order of magnitude deeper exposure than the previous {\it
Chandra} observation, which allows us to cover the entire SNR and to detect new
metal-rich ejecta features. We find a highly non-uniform distribution of
thermodynamic conditions of the X-ray emitting hot gas that correlates well
with the optical [O {\small III}] emission, suggesting the possibility that the
originating supernova explosion of G292.0+1.8 was itself asymmetric. We also

710.2903 | Non-LTE dust nucleation in sub-saturated vapors | We use the kinetic theory of nucleation to explore the properties of dust
nucleation in sub-saturated vapors. Due to radiation losses, the sub-critical
clusters have a smaller temperature compared to their vapor. This alters the
dynamical balance between attachment and detachment of monomers, allowing for
stable nucleation of grains in vapors that are sub-saturated for their
temperature. We find this effect particularly important at low densities and in
the absence of a strong background radiation field. We find new conditions for
stable nucleation in the n-T phase diagram. The nucleation in the non-LTE
regions is likely to be at much slower rate than in the super-saturated vapors.
We evaluate the nucleation rate, warning the reader that it does depend on
poorly substantiated properties of the macro-molecules assumed in the
computation. On the other hand, the conditions for nucleation depend only on
the properties of the large stable grains and are more robust. We finally point
out that this mechanism may be relevant in the early universe as an initial
dust pollution mechanism, since once the interstellar medium is polluted with
dust, mantle growth is likely to be dominant over non-LTE nucleation in the
diffuse medium.

710.2904 | Planets Around Massive Subgiants | Compared to planets around Sun-like stars, relatively little is known about
the occurrence rate and orbital properties of planets around stars more massive
than 1.3 Msun. The apparent deficit of planets around massive stars is due to a
strong selection bias against early-type dwarfs in Doppler-based planet
searches. One method to circumvent the difficulties inherent to massive
main-sequence stars is to instead observe them after they have evolved onto the
subgiant branch. We show how the cooler atmospheres and slower rotation
velocities of subgiants make them ideal proxies for F- and A-type stars. We
present the early results from our planet search that reveal a paucity of

710.2905 | Chiral Random Two-Matrix Theory and QCD with imaginary chemical
potential | We summarise recent results for the chiral Random Two-Matrix Theory
constructed to describe QCD in the epsilon-regime with imaginary chemical
potential. The virtue of this theory is that unquenched Lattice simulations can
be used to determine both low energy constants Sigma and F in the leading order
chiral Lagrangian, due to their respective coupling to quark mass and chemical
potential. We briefly recall the analytic formulas for all density and
individual eigenvalue correlations and then illustrate them in detail in the
simplest, quenched case with imaginary isospin chemical potential. Some
peculiarities are pointed out for this example: i) the factorisation of density
and individual eigenvalue correlation functions for large chemical potential
and ii) the factorisation of the non-Gaussian weight function of bi-orthogonal
polynomials into Gaussian weights with ordinary orthogonal polynomials.

710.2906 | The gl(1|1) super-current algebra: the role of twist and logarithmic
fields | A free field representation of the gl(1|1)_k current algebra at arbitrary
level k is given in terms of two scalar fields and a symplectic fermion. The
primary fields for all representations are explicitly constructed using the
twist and logarithmic fields in the symplectic fermion sector. A closed
operator algebra is described at integer level k. Using a new super spin charge
separation involving gl(1|1)_N and su(N)_0, we describe how the gl(1|1)_N
current algebra can describe a non-trivial critical point of disordered Dirac
fermions. Local gl(1|1) invariant lagrangians are defined which generalize the
Liouville and sine-Gordon theories. We apply these new tools to the spin

710.2909 | Signal and Charge Transfer Efficiency of Few Electrons Clocked on
Microscopic Superfluid Helium Channels | Electrons floating on the surface of liquid helium are possible spin-qubits
for quantum information processing. Varying electric potentials are not
expected to modify spin states, which allows their transport on helium using a
charge-coupled device (CCD)-like array of underlying gates. This approach
depends upon efficient inter-gate transfer of individual electrons.
Measurements are presented here of the charge transfer efficiency (CTE) of few
electrons clocked back and forth above a short microscopic CCD-like structure.

absorption of single quanta of an external ac field. The energy of the quantum
$\hbar\omega$ should be slightly blue-detuned from the energy of a soliton with
momentum $\hbar q$, where $q$ is the external field wavenumber $q$. We
calculate the absorption cross-section and show that it has power-law
dependence on the frequency detuning. This reflects the quantum nature of the
absorption process and the orthogonality catastrophe phenomenon associated with
it.

710.2912 | Updating Probabilities: An Econometric Example | We demonstrate how information in the form of observable data and moment
constraints are introduced into the method of Maximum relative Entropy (ME). A
general example of updating with data and moments is shown. A specific
econometric example is solved in detail which can then be used as a template

710.2915 | The late-time tails in the Reissner-Nordstr\"{o}m spacetime revisited | We propose that the late-time tail problem in the Reissner-Nordstr\"{o}m (RN)
spacetime is dual to a tail problem in the Schwarzschild spacetime with a
different initial data set: at a fixed observation point the asymptotic decay
rate of the fields are equal. This duality is used to find the decay rate for
tails in RN. This decay rate is exactly as in Schwarzschild, including the case
of the extremely-charged RN spacetime (ERN). The only case where any deviation
from the Schwarzschild decay rate is found is the case of the tails along the
event horizon of an ERN spacetime, where the decay rate is the same as at
future null infinity. As observed at a fixed location, the decay rate in ERN is

710.2917 | Comparison of Boltzmann Kinetics with Quantum Dynamics for a Chiral
Yukawa Model Far From Equilibrium | Boltzmann equations are often used to describe the non-equilibrium
time-evolution of many-body systems in particle physics. Prominent examples are
the computation of the baryon asymmetry of the universe and the evolution of
the quark-gluon plasma after a relativistic heavy ion collision. However,
Boltzmann equations are only a classical approximation of the quantum
thermalization process, which is described by so-called Kadanoff-Baym
equations. This raises the question how reliable Boltzmann equations are as
approximations to the complete Kadanoff-Baym equations. Therefore, we present
in this article a detailed comparison of Boltzmann and Kadanoff-Baym equations
in the framework of a chirally invariant Yukawa-type quantum field theory
including fermions and scalars. The obtained numerical results reveal
significant differences between both types of equations. Apart from
quantitative differences, on a qualitative level the late-time universality
respected by Kadanoff-Baym equations is severely restricted in the case of
Boltzmann equations. Furthermore, Kadanoff-Baym equations strongly separate the
time scales between kinetic and chemical equilibration. In contrast to this
standard Boltzmann equations cannot describe the process of quantum-chemical
equilibration, and consequently also cannot feature the above separation of
time scales.

that its Z_N^4 symmetry, which is crucial for the validity of this model, can
break spontaneously in the intermediate coupling region. We investigate in
detail the symmetry breaking point from the weak coupling side. Our simulation

710.292 | Continuum theory for the piezoelectric response of chiral nanotubes
under uniaxial and torsional stresses | We develop and solve a continuum theory for the piezoelectric response of
nanotubes under applied uniaxial and torsional stresses. We find that the
piezoelectric response is controlled by the chiral angle, the aspect ratio, and
two dimensionless parameters specifying the ratio of the strengths of the
electrostatic and elastic energies. The model is solved in two limiting cases
and the solutions are discussed. These systems are found to have several
unexpected physical effects not seen in conventional bulk systems, including a
strong stretch-twist coupling and the development of a significant bound charge
density in addition to a surface charge density. The model is applied to

710.2924 | Neutron Polarisabilities from Deuteron Compton Scattering in \chiEFT | Chiral Effective Field Theory is for photon energies up to 200 MeV the tool
to accurately determine the polarisabilities of the neutron from deuteron
Compton scattering. A multipole analysis reveals that dispersive effects from
an explicit Delta(1232) prove in particular indispensable to understand the
data at 95 MeV measured at SAL. Simple power-counting arguments derived from
nuclear phenomenology lead to the correct Thomson limit and gauge invariance.
At next-to-leading order, the static scalar dipole polarisabilities are
extracted as identical for proton and neutron within the error-bar of available
data: \alpha^n=11.6\pm1.5_stat\pm0.6_Baldin,
\beta^n=3.6\mp1.5_stat\pm0.6_Baldin for the neutron, in units of 10^-4 fm^3,
compared to \alpha^p=11.0\pm1.4_stat\pm0.4_Baldin,
\beta}^p=2.8\mp1.4_stat\pm0.4_Baldin for the proton in the same framework. New
experiments e.g. at MAXlab (Lund) will improve the statistical error-bar.

710.2925 | Bridging over p-wave pi-production and weak processes in few-nucleon
systems with chiral perturbation theory | We focus on a powerful aspect of chiral perturbation theory (chi PT) which
provides us with a ``bridge'' over different reactions. For this purpose, we
study a contact operator which contributes p-wave pi-production and several
weak processes. We fix the unknown coupling of the contact operator using a
matrix element of a low-energy weak process (pp\to de^+\nu_e), and then
calculate the partial wave amplitude (a_0) for the p-wave pi-production (pp\to
pn\pi^+). We find that the chiral operator including the contact term does not
reproduce a_0 extracted from data, showing that the bridging over reactions
with significantly different kinematics is not necessarily successful. We argue
the importance of a specific higher order calculation. In order to gain an
insight into a higher order calculation, we consider a higher order counter

710.2927 | Renormalization group analysis of the chiral pion production operator
for NN\to d\pi | We are interested in the consistency between the cutoff, chiral symmetry, and
the power counting. For this purpose, we apply the Wilsonian renormalization
group (RG) to an operator and then decrease the Wilsonian cutoff. As an
example, we study the s-wave pion production operator for NN\to d\pi, derived
in chiral perturbation theory. We find that the renormalized part of the RG
effective operator is accurately absorbed by chiral counter terms of higher
order with natural coefficients. Thus, the use of the (sharp) cutoff
regularization does not require us to introduce chiral-symmetry-breaking
counter terms, at least in the case of the NN\to d\pi reaction.

710.2928 | Embedding A4 into left-right flavor symmetry: Tribimaximal neutrino
mixing and fermion hierarchy | We address two fundamental aspects of flavor physics: the mass hierarchy and
the large lepton mixing angles. On one side, left-right flavor symmetry
realizes the democratic mass matrix patterns and explains why one family is

as A4 leads to the observed tribimaximal mixing for the leptons. We show that,
by explicitly breaking the left-right flavor symmetry into the diagonal A4, it
is possible to explain both the observed charged fermion mass hierarchies and
quark and lepton mixing angles. In particular we predict a heavy 3rd family,
the tribimaximal mixing for the leptons, and we suggest a possible origin of
the Cabibbo and other mixing angles for the quarks.

observed, in cases where the starting Ni content $x$ in the precursor
Ni$_x$Mn$_{1-x}$O$_4$ phase is small. For particles of approximately the same
size, the exchange bias leads to significant hardening of the magnetization,
with the coercive field scaling nearly linearly with the exchange bias field.

a cominuscule Grassmannian. For each such Grassmannian we define Le-diagrams --
certain fillings of generalized Young diagrams which are in bijection with the
cells of (G/P)+. In the classical cases, we describe Le-diagrams explicitly in
terms of pattern avoidance. We also define a game on diagrams, by which one can
reduce an arbitrary diagram to a Le-diagram. We give enumerative results and
relate our Le-diagrams to other combinatorial objects. Surprisingly, the
totally non-negative cells in the open Schubert cell of the odd and even
orthogonal Grassmannians are (essentially) in bijection with preference
functions and atomic preference functions respectively.

710.2933 | Alternative Derivation of Electromagnetic Cloaks and Concentrators | Beginning with a straightforward formulation of electromagnetic cloaking that
reduces to a boundary value problem involving a single Maxwell first-order
differential equation, explicit formulae for the relative
permittivity-permeability dyadic and fields of spherical and circular
cylindrical annular cloaks are derived in terms of general compressed radial
coordinate functions. The general formulation is based on the requirements that
the cloaking occurs for all possible incident fields and that the cloaks with
frequency w > 0 have continuous tangential E and H fields across their outer
surfaces, and zero normal D and B fields at their inner material surfaces. The
tangential-field boundary conditions at the outer surface of the cloak ensure
zero scattered fields, and the normal-field boundary conditions at the inner
surface of the cloak are compatible with zero total fields inside the interior
cavity of the cloak. For spherical cloaks, unlike cylindrical cloaks, these
boundary conditions lead to all the tangential components of the E and H fields
being continuously zero across their inner surfaces -- cylindrical cloaks
having delta functions in polarization densities at their inner surfaces. For
bodies with no interior free-space cavities, the formulation is used to derive
nonscattering spherical and cylindrical concentrators that magnify the incident
fields near their centers. For static fields (w = 0), the boundary value
formulation is appropriately modified to obtain a permeability dyadic that will
cloak magnetostatic fields. Causality conditions imply that, unlike
magnetostatic cloaking, electrostatic cloaking as well as low-frequency
cloaking for w > 0 is not realizable.

710.2934 | A Tale Of Two Spicules: The Impact of Spicules on the Magnetic
Chromosphere | We use high-resolution observations of the Sun in Ca II H 3968 A from the
Solar Optical Telescope on Hinode to show that there are at least two types of
spicules that dominate the structure of the magnetic solar chromosphere. Both
types are tied to the relentless magnetoconvective driving in the photosphere,
but have very different dynamic properties. ``Type-I'' spicules are driven by
shock waves that form when global oscillations and convective flows leak into
the upper atmosphere along magnetic field lines on 3-7 minute timescales.
``Type-II'' spicules are much more dynamic: they form rapidly (in ~10s), are
very thin (<200km wide), have lifetimes of 10-150s (at any one height) and seem
to be rapidly heated to (at least) transition region temperatures, sending
material through the chromosphere at speeds of order 50-150 km/s. The
properties of Type II spicules suggest a formation process that is a
consequence of magnetic reconnection, typically in the vicinity of magnetic
flux concentrations in plage and network. Both types of spicules are observed
to carry Alfven waves with significant amplitudes of order 20 km/s.

optimized for the gamma ray energy regime of 10 TeV to 100 TeV, but with a
threshold of ~1 to a few TeV. It will offer a collecting area of 10 km2 above
energies of 10 TeV. In the initial phase, a cell of 3 to 5 modest-sized
telescopes, each with 10-30 m2 mirror area, is suggested for an Australian
site. A possible expansion of the array could comprise many such cells. Here we
present work on configuration and technical issues from our simulation studies
of the array. Working topics include array layout, telescope size and optics,
camera field of view, telescope trigger system, electronics, and site surveys.

710.2936 | Optimal design problems in rough inhomogeneous media. Existence theory | This paper settles the existence question for a rather general class of
convex optimal design problems with a volume constraint. In low dimensions, we
prove the existence of an optimal configuration for general convex minimization
problems ruled by bounded measurable degenerate elliptic operators. Under a
mild continuity assumption on the medium, the free boundary is proven to enjoy
the appropriate weak geometry and we establish the existence of an optimal

\alpha in R(S^1). These R(S^1)-graded TR-groups are the equivariant homotopy
groups naturally associated to the S^1-spectrum THH(F_p), the topological

Hesselholt and Madsen, provides the first example of the R(S^1)-graded
TR-groups of a ring. These groups arise in algebraic K-theory computations, and
are particularly important to the understanding of the algebraic K-theory of
non-regular schemes.

710.2939 | Uncovering individual and collective human dynamics from mobile phone
records | Novel aspects of human dynamics and social interactions are investigated by
means of mobile phone data. Using extensive phone records resolved in both time
and space, we study the mean collective behavior at large scales and focus on
the occurrence of anomalous events. We discuss how these spatiotemporal
anomalies can be described using standard percolation theory tools. We also
investigate patterns of calling activity at the individual level and show that
the interevent time of consecutive calls is heavy-tailed. This finding, which

710.294 | Recent Advances in the Theory of Nuclear Forces and its Impact on
Microscopic Nuclear Structure | The theory of nuclear forces has made great progress since the turn of the
millenium using the framework of chiral effective field theory (ChEFT). The
advantage of this approach, which was originally proposed by Weinberg, is that
it has a firm basis in quantum-chromodynamics and allows for quantitative
calculations. Moreover, this theory generates two-nucleon forces (2NF) and
many-body forces on an equal footing and provides an explanation for the
empirically known fact that 2NF >> 3NF >> 4NF. I will present the recent
advances in more detail and put them into historical context. In addition, I
will also provide a critical evaluation of the progress made including a
discussion of the limitations of the ChEFT approach.

710.2941 | Why Is Supercritical Disk Accretion Feasible? | Although the occurrence of steady supercritical disk accretion onto a black
hole has been speculated about since the 1970s, it has not been accurately
verified so far. For the first time, we previously demonstrated it through
two-dimensional, long-term radiation-hydrodynamic simulations. To clarify why
this accretion is possible, we quantitatively investigate the dynamics of a
simulated supercritical accretion flow with a mass accretion rate of ~10^2
L_E/c^2 (with L_E and c being, respectively, the Eddington luminosity and the
speed of light). We confirm two important mechanisms underlying supercritical
disk accretion flow, as previously claimed, one of which is the radiation
anisotropy arising from the anisotropic density distribution of very optically
thick material. We qualitatively show that despite a very large radiation
energy density, E_0>10^2L_E/(4 pi r^2 c) (with r being the distance from the
black hole), the radiative flux F_0 cE_0/tau could be small due to a large
optical depth, typically tau 10^3, in the disk. Another mechanism is photon
trapping, quantified by vE_0, where v is the flow velocity. With a large |v|
and E_0, this term significantly reduces the radiative flux and even makes it
negative (inward) at r<70r_S, where r_S is the Schwarzschild radius. Due to the
combination of these effects, the radiative force in the direction along the
disk plane is largely attenuated so that the gravitational force barely exceeds
the sum of the radiative force and the centrifugal force. As a result, matter
can slowly fall onto the central black hole mainly along the disk plane with
velocity much less than the free-fall velocity, even though the disk luminosity
exceeds the Eddington luminosity. Along the disk rotation axis, in contrast,
the strong radiative force drives strong gas outflows.

710.2942 | Rapidity gap survival in the black-disk regime | We summarize how the approach to the black--disk regime (BDR) of strong
interactions at TeV energies influences rapidity gap survival in exclusive hard
diffraction pp--> p + H + p (H =dijet, \bar Q Q, Higgs). Employing a recently
developed partonic description of such processes, we discuss (a) the
suppression of diffraction at small impact parameters by soft spectator
interactions in the BDR; (b) further suppression by inelastic interactions of
hard spectator partons in the BDR; (c) effects of correlations between hard and
soft interactions, as suggested by various models of proton structure (color
fluctuations, spatial correlations of partons). Hard spectator interactions in
the BDR substantially reduce the rapidity gap survival probability at LHC
energies compared to previously reported estimates.

710.2943 | Global quark polarization in non-central $A+A$ collisions | Partons produced in the early stage of non-central heavy-ion collisions can
develop a longitudinal fluid shear because of unequal local number densities of
participant target and projectile nucleons. Under such fluid shear, local
parton pairs with non-vanishing impact parameter have finite local relative
orbital angular momentum along the direction opposite to the reaction plane.
Such finite relative orbital angular momentum among locally interacting quark
pairs can lead to global quark polarization along the same direction due to
spin-orbital coupling. Local longitudinal fluid shear is estimated within both
Landau fireball and Bjorken scaling model of initial parton production. Quark
polarization through quark-quark scatterings with the exchange of a thermal
gluon is calculated beyond small-angle scattering approximation in a
quark-gluon plasma. The polarization is shown to have a non-monotonic
dependence on the local relative orbital angular momentum dictated by the
interplay between electric and magnetic interaction. It peaks at a value of
relative orbital angular momentum which scales with the magnetic mass of the
exchanged gluons. With the estimated small longitudinal fluid shear in
semi-peripheral $Au+Au$ collisions at the RHIC energy, the final quark
polarization is found to be small $|P_q|<0.04$ in the weak coupling limit.
Possible behavior of the quark polarization in the strong coupling limit and
implications on the experimental detection of such global quark polarization at
RHIC and LHC are also discussed.

710.2944 | Gamow-Teller strength for the analog transitions to the first T=1/2,
J^pi=3/2- states in 13C and 13N and the implications for Type Ia supernovae | The Gamow-Teller strength for the transition from the ground state of 13C to
the T=1/2, J^pi=3/2- excited state at 3.51 MeV in 13N is extracted via the
13C(3He,t) reaction at 420 MeV. In contrast to results from earlier (p,n)
studies on 13C, a good agreement with shell-model calculations and the
empirical unit cross section systematics from other nuclei is found. The
results are used to study the analog 13N(e-,v_e)13C reaction, which plays a
role in the pre-explosion convective phase of type Ia supernovae. Although the
differences between the results from the (3He,t) and (p,n) data significantly
affect the deduced electron-capture rate and the net heat-deposition in the

where the motion of valence neutrons is described in the cluster orbital shell

the Gamow states in the complex scaling method. We obtain five resonances and
investigate their properties from the configurations. In particular, the 1/2-

while the experimental determination of the position of this state is not so
clear. We also evaluate the spectroscopic factors of the 6He-n components in
the obtained 7He resonances. The importance of the 6He(2+) state is shown in
several states of 7He.

710.2946 | An universal algorithm of calculating terms of atomic many-body
perturbation theory | An algorithm, based on numerical description of the terms of many-body
perturbation theory (Goldstone diagrams), is presented. The algorithm allows
the use of the same piece of computer code to evaluate any particular diagram
in any specific order of the perturbation theory or to calculate similar terms
in other areas of the many-body theory, like e.g. terms in the coupled-cluster
equations. The use of the algorithm is illustrated by calculating the second
and third order correlation corrections to the removal energies of electrons
from the ground state of sodium, copper and gallium and by calculating the

Landau gauge. We assume a two-pole structure for the quark spectral function,
which is numerically found to work quite well for any value of \kappa. It is
shown that in the chiral limit the quark spectral function has two collective
modes that correspond to the normal and plasmino excitations, while it is

710.2952 | The "mean king's problem" with continuous variables | We present the solution to the "mean king's problem" in the continuous
variable setting. We show that in this setting, the outcome of a
randomly-selected projective measurement of any linear combination of the
canonical variables x and p can be ascertained with arbitrary precision.
Moreover, we show that the solution is in turn a solution to an associated
"conjunctive" version of the problem, unique to continuous variables, where the
inference task is to ascertain all the joint outcomes of a simultaneous
measurement of any number of linear combinations of x and p.
| quant-ph | we present the solution to the mean kings problem in the continuous variable setting we show that in this setting the outcome of a randomlyselected projective measurement of any linear combination of the canonical variables x and p can be ascertained with arbitrary precision moreover we show that the solution is in turn a solution to an associated conjunctive version of the problem unique to continuous variables where the inference task is to ascertain all the joint outcomes of a simultaneous measurement of any number of linear combinations of x and p | [['we', 'present', 'the', 'solution', 'to', 'the', 'mean', 'kings', 'problem', 'in', 'the', 'continuous', 'variable', 'setting', 'we', 'show', 'that', 'in', 'this', 'setting', 'the', 'outcome', 'of', 'a', 'randomlyselected', 'projective', 'measurement', 'of', 'any', 'linear', 'combination', 'of', 'the', 'canonical', 'variables', 'x', 'and', 'p', 'can', 'be', 'ascertained', 'with', 'arbitrary', 'precision', 'moreover', 'we', 'show', 'that', 'the', 'solution', 'is', 'in', 'turn', 'a', 'solution', 'to', 'an', 'associated', 'conjunctive', 'version', 'of', 'the', 'problem', 'unique', 'to', 'continuous', 'variables', 'where', 'the', 'inference', 'task', 'is', 'to', 'ascertain', 'all', 'the', 'joint', 'outcomes', 'of', 'a', 'simultaneous', 'measurement', 'of', 'any', 'number', 'of', 'linear', 'combinations', 'of', 'x', 'and', 'p']] | [-0.14100266227045644, 0.042027277311559454, -0.08866622703878776, 0.00868493421433453, -0.06622136089667353, -0.11228295361481445, 0.08838830575215346, 0.34486968693849834, -0.3357161666145143, -0.270049957740728, 0.1014495364892671, -0.2495316006470998, -0.11305651969134646, 0.15979338947521604, -0.10376931599887979, 0.07331233234752131, 0.07991922492637178, 0.08214549031918464, -0.0898473537982563, -0.26629058248363435, 0.323072866131754, -0.009134275853917326, 0.21797954419668278, -0.024016866117523496, 0.14750292095477166, 0.07406094586780376, -0.01581376739372702, 0.0683337927431516, -0.08604749111011346, 0.10101503220579142, 0.27336009230677283, 0.17716452214138015, 0.29396364993780205, -0.35660934856455045, -0.17943898567666663, 0.1984231149494324, 0.07812939790765876, 0.08556602563729267, 0.017017415906910017, -0.23374593725589954, 0.09802208564724424, -0.13325219548752773, -0.1164166238968787, -0.07294225999478089, 0.031172945832266756, 0.022128367816786402, -0.35718811777136894, 0.058871167509452156, 0.0820932779609828, 0.024683332900800135, -0.08149380331261731, -0.08191188009273585, 0.013452894540260668, 0.08950831573051603, 0.034627076567393604, 0.059299292103589876, 0.05789271127128893, -0.11540101389856199, -0.13132536702829858, 0.3639679485425839, -0.07182102325453382, -0.2452386934537967, 0.13632411537084566, -0.18261724977713564, -0.15119275570791418, 0.08720355150897217, 0.17908533611942246, 0.16258406491302277, -0.1268200039073987, 0.09412465693363313, -0.10306625131963064, 0.2068535053252202, 0.027912616476659543, -0.00997917413326871, 0.14389862665785072, 0.1312681376711344, 0.08967198297361155, 0.12863510410154602, -0.0620934066530975, -0.04908128731134955, -0.34088808364923234, -0.20668383513617775, -0.16507043096910068, 0.06680322516679196, -0.10419909099247256, -0.164501643921856, 0.3686784349543893, 0.1231163727251165, 0.2265827964697762, 0.0731226141544302, 0.2420738794962349, 0.1349290658051715, -0.010109946091213951, 0.03625587296467173, 0.18479828974839463, 0.1229918475804405, 0.03105852050382806, -0.22196029335179407, 0.09459241537336746, 0.04003770898460694] |
