710.4853 | Erratum: Propagation Effects on the Breakdown of a Linear Amplifier
Model: Complex-Mass Schrodinger Equation Driven by the Square of a Gaussian
Field | The proof of the inequality $\lambda_{q}(x,t)\le (q\mu_{x,t} -0^+)^{-1}$ [p
750, below Eq. (29)] is based on the statement that ${\cal E}(x,t;s)$ is an
entire function of $s\in {\mathbb C}^M$ [see below Eq. (30)]. But according to
Equation (9) and Lemma 1, all we know is that ${\cal E}(x,t;s)$ is an entire
function of $k(s)\in {\mathbb R}^N$. Nevertheless, the above inequality holds,
hence the proposition 1.

710.4854 | Big bang nucleosynthesis as a probe of fundamental "constants" | Big Bang nucleosynthesis (BBN) is the earliest sensitive probe of the values
of many fundamental particle physics parameters. We have found the leading
linear dependences of primordial abundances on all relevant parameters of the
standard BBN code, including binding energies and nuclear reaction rates. This
enables us to set limits on possible variations of fundamental parameters. We
find that 7Li is expected to be significantly more sensitive than other species
to many fundamental parameters, a result which also holds for variations of
coupling strengths in grand unified (GUT) models. Our work also indicates which
areas of nuclear theory need further development if the values of ``constants''
are to be more accurately probed.

710.4856 | Extending the scope of microscopic solvability: Combination of the
Kruskal-Segur method with Zauderer decomposition | Successful applications of the Kruskal-Segur approach to interfacial pattern
formation have remained limited due to the necessity of an integral formulation
of the problem. This excludes nonlinear bulk equations, rendering convection
intractable. Combining the method with Zauderer's asymptotic decomposition
scheme, we are able to strongly extend its scope of applicability and solve
selection problems based on free boundary formulations in terms of partial
differential equations alone. To demonstrate the technique, we give the first

710.4857 | Scintillation light produced by low-energy beams of highly-charged ions | Measurements have been performed of scintillation light intensities emitted
from various inorganic scintillators irradiated with low-energy beams of
highly-charged ions from an electron beam ion source (EBIS) and an electron
cyclotron resonance ion source (ECRIS). Beams of xenon ions Xe$^{q+}$ with
various charge states between $q$=2 and $q$=18 have been used at energies
between 5 keV and 17.5 keV per charge generated by the ECRIS. The intensity of
the beam was typically varied between 1 and 100 nA. Beams of highly charged
residual gas ions have been produced by the EBIS at 4.5 keV per charge and with
low intensities down to 100 pA. The scintillator materials used are flat
screens of P46 YAG and P43 phosphor. In all cases, scintillation light emitted
from the screen surface was detected by a CCD camera. The scintillation light
intensity has been found to depend linearly on the kinetic ion energy per time
deposited into the scintillator, while up to $q$=18 no significant contribution
from the ions' potential energy was found. We discuss the results on the
background of a possible use as beam diagnostics e.g. for the new HITRAP
facility at GSI, Germany.

710.4858 | Experimentally feasible quantum erasure-correcting code for continuous
variables | We devise a scheme that protects quantum coherent states of light from
probabilistic losses, thus achieving the first continuous-variable quantum
erasure-correcting code. If the occurrence of erasures can be probed, then the
decoder enables, in principle, a perfect recovery of the original light states.
Otherwise, if supplemented with postselection based on homodyne detection, this

710.4859 | Orbital eccentricities of binary systems with a former AGB star | Many binary stellar systems in which the primary star is beyond the
asymptotic giant branch (AGB) evolutionary phase show significant orbital
eccentricities whereas current binary interaction models predict their orbits
to be circularised. We analyse how the orbital parameters in a system are
modified under mass loss and mass exchange among its binary components and
propose a model for enhanced mass-loss from the AGB star due to tidal
interaction with its companion, which allows a smooth transition between the
wind and Roche-lobe overflow mass-loss regimes. We explicitly follow its effect
along the orbit on the change of eccentricity and orbital semi-major axis, as
well as the effect of accretion by the companion. We calculate timescales for
the variation of these orbital parameters and compare them to the tidal
circularisation timescale. We find that in many cases, due to the enhanced mass
loss of the AGB component at orbital phases closer to the periastron, the net
eccentricity growth rate in one orbit is comparable to the rate of tidal
circularisation. We show that with this eccentricity enhancing mechanism it is
possible to reproduce the orbital period and eccentricity of the Sirius system,
which under the standard assumptions of binary interaction is expected to be
circularised. We also show that this mechanism may provide an explanation for
the eccentricities of most barium star systems, which are expected to be
circularised due to tidal dissipation. By proposing a tidally enhanced model of
mass loss from AGB stars we find a mechanism which efficiently works against
the tidal circularisation of the orbit, which explains the significant
eccentricities observed in binary systems containing a white dwarf and a less
evolved companion, such as Sirius and systems with barium stars.

710.486 | Loschmidt cooling by time reversal of atomic matter waves | We propose an experimental scheme which allows to realize approximate time
reversal of matter waves for ultracold atoms in the regime of quantum chaos. We
show that a significant fraction of the atoms return back to their original
state, being at the same time cooled down by several orders of magnitude. We
give a theoretical description of this effect supported by extensive numerical

710.4862 | Intersective polynomials and polynomial Szemeredi theorem | Let $P=\{p_{1},\ld,p_{r}\}\subset\Q[n_{1},\ld,n_{m}]$ be a family of
polynomials such that $p_{i}(\Z^{m})\sle\Z$, $i=1,\ld,r$. We say that the
family $P$ has {\it PSZ property} if for any set $E\sle\Z$ with
$d^{*}(E)=\limsup_{N-M\ras\infty}\frac{|E\cap[M,N-1]|}{N-M}>0$ there exist
infinitely many $n\in\Z^{m}$ such that $E$ contains a polynomial progression of
the form \hbox{$\{a,a+p_{1}(n),\ld,a+p_{r}(n)\}$}. We prove that a polynomial
family $P=\{p_{1},\ld,p_{r}\}$ has PSZ property if and only if the polynomials
$p_{1},\ld,p_{r}$ are {\it jointly intersective}, meaning that for any $k\in\N$
there exists $n\in\Z^{m}$ such that the integers $p_{1}(n),\ld,p_{r}(n)$ are
all divisible by $k$. To obtain this result we give a new ergodic proof of the
polynomial Szemer\'{e}di theorem, based on the fact that the key to the
phenomenon of polynomial multiple recurrence lies with the dynamical systems
defined by translations on nilmanifolds. We also obtain, as a corollary, the
following generalization of the polynomial van der Waerden theorem: If
$p_{1},\ld,p_{r}\in\Q[n]$ are jointly intersective integral polynomials, then
for any finite partition of $\Z$, $\Z=\bigcup_{i=1}^{k}E_{i}$, there exist

710.4863 | Near-infrared adaptive optics imaging of high redshift quasars | The properties of high redshift quasar host galaxies are studied, in order to
investigate the connection between galaxy evolution, nuclear activity, and the
formation of supermassive black holes. We combine new near-infrared
observations of three high redshift quasars (2 < z < 3), obtained at the ESO
Very Large Telescope equipped with adaptive optics, with selected data from the
literature. For the three new objects we were able to detect and characterize
the properties of the host galaxy, found to be consistent with those of massive
elliptical galaxies of M(R) ~ -24.7 for the one radio loud quasar, and M(R) ~
-23.8 for the two radio quiet quasars. When combined with existing data at
lower redshift, these new observations depict a scenario where the host
galaxies of radio loud quasars are seen to follow the expected trend of
luminous (~5L*) elliptical galaxies undergoing passive evolution. This trend is
remarkably similar to that followed by radio galaxies at z > 1.5. Radio quiet
quasars hosts also follow a similar trend but at a lower average luminosity
(~0.5 mag dimmer). The data indicate that quasar host galaxies are already
fully formed at epochs as early as ~2 Gyr after the Big Bang and then passively
fade in luminosity to the present epoch.

710.4864 | Conformal invariance and finiteness theorems for non-planar
beta-deformed N=4 SYM theory | We study the conformal invariance of non-planar beta-deformed N=4 SYM theory
using the coupling constant reduction (CCR) formalism. We show that up to order
g^10, differently from the planar case, we can remove the scheme dependence in
the definition of the theory without reducing to the real beta case. We also

710.4867 | Bi-clique Communities | We present a novel method for detecting communities in bipartite networks.
Based on an extension of the $k$-clique community detection algorithm, we
demonstrate how modular structure in bipartite networks presents itself as
overlapping bicliques. If bipartite information is available, the bi-clique
community detection algorithm retains all of the advantages of the $k$-clique
algorithm, but avoids discarding important structural information when
performing a one-mode projection of the network. Further, the bi-clique
community detection algorithm provides a new level of flexibility by
incorporating independent clique thresholds for each of the non-overlapping

710.4868 | SO(10)-like Superstring Standard Model with R-parity from the Heterotic
String | We construct a supersymmetric standard model in the context of the Z_{12-I}
orbifold compactification of the E_8 x E_8' heterotic string theory. The gauge
group is SU(3)_c x SU(2)_L x U(1)_Y x U(1)^4 x [SO(10) x U(1)^3]' with
sin^2\theta_W = 3/8. We obtain three families of SO(10) spinor-like chiral
matter states, and Higgs doublets. All other extra states are exactly
vector-like under the standard model gauge symmetry. There are numerous
standard model singlets, many of which get VEVs such that only the standard
model gauge symmetry survives and desired Yukawa couplings can be generated at
lower energies. In particular, all vector-like exotic states achieve superheavy
masses and the R-parity can be preserved.

thirteen sources were detected at our longest baseline of $\sim$50 M$\lambda$,
and their images are presented. Seven of them are the first VLBI images at 6.7
GHz. This high detection rate and the small fringe spacing of $\sim$4
milli-arcsecond suggest that most of the methanol maser sources have compact
structure. Given this compactness as well as the known properties of long-life
and small internal-motion, this methanol maser line is suitable for astrometry
with VLBI.

710.4874 | Decays of the Littlest Higgs Z_H and the Onset of Strong Dynamics | The Little Higgs mechanism, as realized in various models, requires a set of
new massive gauge bosons, some of which mix with gauge bosons of the Standard
Model. For a range of mixing angles the coupling of gauge bosons to scalars can
become strong, ultimately resulting in a breakdown of perturbative calculation.
This phenomenon is studied in the Littlest Higgs model, where the approach to
strong dynamics is characterized by increasing tree-level decay widths of the
neutral Z_H boson to lighter gauge bosons plus multiple scalars. These
increasing widths suggest a distinctive qualitative collider signature for the
approach to the strong coupling regime of large Higgs and other scalar
multiplicities. In this work we catalog the kinematically allowed three-body
decays of the Z_H, and calculate the partial width of the process Z_H to Z_L H
H. This partial width is found to be larger than the comparable two-body decay
Z_H to Z_L H for values of the SU(2) mixing angle cosine(theta) less than 0.13,
indicating divergence of the littlest Higgs sigma field expansion at values of
cosine(theta) larger than a simple parametric calculation would suggest.
Additionally, we present analytical expressions for all two-body decays of the
Littlest Higgs Z_H gauge boson, including the effects of all final-state
masses.

710.4875 | A discrete version and stability of Brunn Minkowski inequality | In the first part of the paper, we define an approximated Brunn-Minkowski
inequality which generalizes the classical one for length spaces. Our new
definition based only on distance properties allows us also to deal with
discrete spaces. Then we show the stability of our new inequality under a
convergence of metric measure spaces. This result gives as a corollary the
stability of the classical Brunn-Minkowski inequality for geodesic spaces. The
proof of this stability was done for different inequalities (curvature
dimension inequality, metric contraction property) but as far as we know not
for the Brunn-Minkowski one. In the second part of the paper, we show that
every metric measure space satisfying classical Brunn-Minkowski inequality can

stabilisation scenario with a supersymmetric uplifting D-term. The resulting

that the gaugino condensates vary during inflation. The resulting spectral

710.4879 | QT-Symmetry and Weak Pseudo-Hermiticity | For an invertible (bounded) linear operator Q acting in a Hilbert space
${\cal H}$, we consider the consequences of the QT-symmetry of a non-Hermitian
Hamiltonian $H:{\cal H}\to{\cal H}$ where T is the time-reversal operator. If H
is symmetric in the sense that ${\cal T} H^\dagger {\cal T}=H$, then
QT-symmetry is equivalent to Q^{-1}-weak-pseudo-Hermiticity. But in general
this equivalence does not hold. We show this using some specific examples.
Among these is a large class of non-PT-symmetric Hamiltonians that share the
spectral properties of PT-symmetric Hamiltonians.

710.488 | Perturbative and non-perturbative aspects of QED_{3} | In this work we review various findings in the planar quantum physics with
the special emphasis on the two-component quantum electrodynamics in
three-dimensional spacetime (QED_{3}) with the Chern-Simons (CS) term. First
the classical electrodynamics is briefly outlined. Then we construct and
classify the unitary irreducible representations of the Poincare group and
connect them to various covariant fields. Subtleties with discrete symmetries
arising in QED_{3} are also discussed. Quantization of the free gauge field
with and without the CS term is performed in Coulomb gauge. Subsequently we
discuss the ultraviolet behavior of the theory in perturbative regime and
perform some one-loop calculations. The induced CS term is examined using the
effective action formalism. The non-relativistic electron-electron interactions
are considered in the Maxwell-Chern-Simons theory and the possibility of bound
states is briefly discussed. We also examine the non-relativistic scattering of
two anyons in the pure CS theory to one-loop order.

ground state is described with the relativistic Hartree-Bogoliubov model, and
the relevant transitions to excited nuclear states are calculated in the
relativistic quasiparticle random phase approximation. Illustrative test
calculations are performed for charged-current neutrino reactions on $^{12}$C,
$^{16}$O, $^{56}$Fe, and $^{208}$Pb, and results compared with previous studies
and available data. Using the experimental neutrino fluxes, the averaged cross
sections are evaluated for nuclei of interest for neutrino detectors. We
analyze the total neutrino-nucleus cross sections, and the evolution of the
contribution of the different multipole excitations as a function of neutrino
energy. The cross sections for reactions of supernova neutrinos on $^{16}$O and
$^{208}$Pb target nuclei are analyzed as functions of the temperature and
chemical potential.

very accurately both analytically and numerically how the Drude dispersive
model, assuming the relaxation is nonzero at zero temperature (which is the
case when impurities are present), gives consistent results for the Casimir
free energy at low temperatures. Specifically, we find that the free energy
consists essentially of two terms, one leading term proportional to T^2, and a
next term proportional to T^{5/2}. Both these terms give rise to zero Casimir
entropy as T -> 0, thus in accordance with Nernst's theorem.

710.4883 | The transiting exoplanet host star GJ 436: a test of stellar evolution
models in the lower main sequence, and revised planetary parameters | Knowledge of the stellar parameters for the parent stars of transiting
exoplanets is pre-requisite for establishing the planet properties themselves,
and often relies on stellar evolution models. GJ 436, which is orbited by a
transiting Neptune-mass object, presents a difficult case because it is an M
dwarf. Stellar models in this mass regime are not as reliable as for higher
mass stars, and tend to underestimate the radius. Here we use constraints from
published transit light curve solutions for GJ 436 along with other
spectroscopic quantities to show how the models can still be used to infer the
mass and radius accurately, and at the same time allow the radius discrepancy
to be estimated. Similar systems should be found during the upcoming Kepler
mission, and could provide in this way valuable constraints to stellar
evolution models in the lower main sequence. The stellar mass and radius of GJ
436 are M = 0.452 [-0.012,+0.014] M(Sun) and R = 0.464 [-0.011,+0.009] R(Sun),
and the radius is 10% larger than predicted by the standard models, in
agreement with previous results from well studied double-lined eclipsing
binaries. We obtain an improved planet mass and radius of M = 23.17 +/- 0.79
M(Earth) and R = 4.22 [-0.10,+0.09] R(Earth), a density of rho = 1.69
[-0.12,+0.14] g/cm3, and an orbital semimajor axis of a = 0.02872 +/- 0.00027

710.4884 | Upper Bounds for the Security of two Distributed-Phase Reference
Protocols of Quantum Cryptography (Coherent-One-Way and
Differential-Phase-Shift) | The Differential-Phase-Shift (DPS) and the Coherent-One-Way (COW) are among
the most practical protocols for quantum cryptography, and are therefore the
object of fast-paced experimental developments. The assessment of their
security is also a challenge for theorists: the existing tools, that allow to
prove security against the most general attacks, do not apply to these two
protocols in any straightforward way. We present new upper bounds for their
security in the limit of large distances ($d \gtrsim 50$km with typical values
in optical fibers) by considering a large class of collective attacks, namely
those in which the adversary attaches ancillary quantum systems to each pulse
or to each pair of pulses. We introduce also two modified versions of the COW
protocol, which may prove more robust than the original one.

710.4886 | Network synchronization: Optimal and Pessimal Scale-Free Topologies | By employing a recently introduced optimization algorithm we explicitely
design optimally synchronizable (unweighted) networks for any given scale-free
degree distribution. We explore how the optimization process affects
degree-degree correlations and observe a generic tendency towards
disassortativity. Still, we show that there is not a one-to-one correspondence
between synchronizability and disassortativity. On the other hand, we study the
nature of optimally un-synchronizable networks, that is, networks whose
topology minimizes the range of stability of the synchronous state. The
resulting ``pessimal networks'' turn out to have a highly assortative
string-like structure. We also derive a rigorous lower bound for the Laplacian

710.4888 | Hypernuclear production by ($\gamma, K^+$) reaction within a
relativistic model | Within a fully covariant model based on an effective Lagrangian picture, we
investigate the hypernuclear production in photon-nucleus interaction on $
^{16}$O target. The explicit kaon production vertex is described via creation,
propagation and decay into relevant channel of $N^*$(1650), $N^*$(1710), and
$N^*$(1720) intermediate baryonic resonance states in the initial interaction
of the incident photon with one of the target protons. Bound state nucleon and
hyperon wave functions are obtained by solving the Dirac equation. Using vertex
parameters determined in the previous studies, contributions of the $N^*$(1710)
baryonic resonance dominate the total production cross sections which are found
to peak at photon energies below 1 GeV. The results show that photoproduction
is the most appropriate means for studying the unnatural parity hypernuclear
states, thus accessing the spin dependence of the hyperon-nucleon interaction.

710.4889 | Phenomenology of the 1/N$_f$ Expansion for Field Theories in Extra
Dimensions | In this paper we review the properties of the 1/$N_f$ expansion in
multidimensional theories. Contrary to the usual perturbative expansion it is
renormalizable and contains only logarithmic divergencies. The price for it is
the presence of ghost states which, however, in certain cases do not contribute
to physical amplitudes. In this case the theory is unitary and one can
calculate the cross-sections. As an example we consider the differential cross
section of elastic $eq \to eq$ scattering in $D=7,11,...$-dimensional world. We
look also for the unification of the gauge couplings in multidimensional

710.4892 | Collisional Quenching at Ultralow Energies: Controlling Efficiency with
Internal State Selection | Calculations have been carried out for the vibrational quenching of excited
H$_2$ molecules which collide with Li$^+$ ions at ultralow energies. The
dynamics has been treated exactly using the well known quantum coupled-channel
expansions over different initial vibrational levels. The overall interaction
potential has been obtained from the calculations carried out earlier in our
group using highly correlated ab initio methods. The results indicate that
specific features of the scattering observables, e.g. the appearance of
Ramsauer-Townsend minima in elastic channel cross sections and the marked
increase of the cooling rates from specific initial states, can be linked to
potential properties at vanishing energies (sign and size of scattering
lengths) and to the presence of either virtual states or bound states. The
suggestion is made that by selecting the initial state preparation of the

710.4893 | A Multi-coloured survey of NGC 253 with XMM-Newton | There is a large body of work that has used the excellent Chandra
observations of nearby galaxies with neglible low mass X-ray binary (LMXB)
populations. This has culminated in a ``Universal'' X-ray luminosity function
(XLF) for high mass X-ray binaries (HMXBs). However, a number of methods have
been used to convert from source intensities to luminosities when creating
these XLFs. We have taken advantage of the XMM-Newton observations of the
nearby starbursting spiral galaxy NGC 253 to test some of these methods. We
find the luminosities derived from these various methods to vary by a factor of
$\sim$3. We also find the most influential factor in the conversion from
intensity to luminosity to be the absorption. We therefore conclude that a more
consistent approach is required for determining the true Universal XLF for
HMXBs. Ideally, this would involve individual spectral fitting of each X-ray
source. Certainly, the line-of-sight absorption should be determined from the
observations rather than assuming Galactic absorption. We find the best
approach for obtaining an XLF from low-count data to be the splitting of the
X-ray sources into two or more intensity intervals, and obtaining a conversion
from intensity to flux for each group from spectral modelling of the summed
spectrum of that group.

710.4894 | The EPR experiment in the energy-based stochastic reduction framework | We consider the EPR experiment in the energy-based stochastic reduction
framework. A gedanken set up is constructed to model the interaction of the
particles with the measurement devices. The evolution of particles' density
matrix is analytically derived. We compute the dependence of the
disentanglement rate on the parameters of the model, and study the dependence

710.4896 | LAW: A Tool for Improved Productivity with High-Performance Linear
Algebra Codes. Design and Applications | LAPACK and ScaLAPACK are arguably the defacto standard libraries among the
scientific community for solving linear algebra problems on sequential,
shared-memory and distributed-memory architectures. While ease of use was a
major design goal for the ScaLAPACK project; with respect to its predecessor
LAPACK; it is still a non-trivial exercise to develop a new code or modify an
existing LAPACK code to exploit processor grids, distributed-array descriptors
and the associated distributed-memory ScaLAPACK/PBLAS routines. In this paper,
we introduce what we believe will be an invaluable development tool for the
scientific code developer, which exploits ad-hoc polymorphism, derived-types,
optional arguments, overloaded operators and conditional compilation in Fortran
95, to provide wrappers to a subset of common linear algebra kernels. These
wrappers are introduced to facilitate the abstraction of low-level details
which are irrelevant to the science being performed, such as target platform
and execution model. By exploiting this high-level library interface, only a
single code source is required with mapping onto a diverse range of execution
models performed at link-time with no user modification. We conclude with a
case study whereby we describe application of the LAW library in the
implementation of the well-known Chebyshev Matrix Exponentiation algorithm for
Hermitian matrices.

710.4897 | Nuclear PDFs from neutrino deep inelastic scattering | We study nuclear effects in charged current deep inelastic neutrino-iron
scattering in the frame-work of a chi^2 analysis of parton distribution
functions. We extract a set of iron PDFs and show that under reasonable
assumptions it is possible to constrain the valence, light sea and strange
quark distributions. Our iron PDFs are used to compute x_{Bj}-dependent and
Q^2-dependent nuclear correction factors for iron structure functions which are
required in global analyses of free nucleon PDFs. We compare our results with
nuclear correction factors from neutrino-nucleus scattering models and
correction factors for charged lepton-iron scattering. We find that, except for
very high x_{Bj}, our correction factors differ in both shape and magnitude
from the correction factors of the models and charged-lepton scattering.

710.4899 | Derivation via free energy conservation constraints of gyrofluid
equations with finite-gyroradius electromagnetic nonlinearities | The derivation of electromagnetic gyrofluid equations is made systematic by
using the Hermite polynomial form of the underlying delta-f gyrokinetic
distribution function. The gyrokinetic free-energy functional is explicitly
used to set up the model. The gyrofluid free energy follows directly. The
interaction term in the gyrokinetic Lagrangian is used to obtain the gyrofluid
counterpart, from which the polarisation equation follows. One closure rule is
decided for taking moments over the kinetic gyroaveraging operator. These steps
fix the rest of the derivation of the conservative part of the gyrofluid
equations. Dissipation is then added in a form to obtain positive definite
dissipation and to obtain the collisional fluid equations in their appropriate
limit. Existing results are recovered, with the addition of a completely

710.49 | Chiral Symmetry Breaking in Brane Models | We discuss the chiral symmetry breaking in general intersecting Dq/Dp brane
models consisting of N_c Dq-branes and a single Dp-brane with an s-dimensional
intersection. There exists a QCD-like theory localized at the intersection and
the Dq/Dp model gives a holographic description of it. The rotational symmetry
of directions transverse to both of the Dq and Dp-branes can be identified with
a chiral symmetry, which is non-Abelian for certain cases. The asymptotic
distance between the Dq-branes and the Dp-brane corresponds to a quark mass. By
studying the probe Dp-brane dynamics in a Dq-brane background in the near
horizon and large N_c limit we find that the chiral symmetry is spontaneously
broken and there appear (pseudo-)Nambu-Goldstone bosons. We also discuss the
models at finite temperature.

710.4901 | Optical detection of single electron spin resonance in a quantum dot | We demonstrate optically detected spin resonance of a single electron
confined to a self-assembled quantum dot. The dot is rendered dark by resonant
optical pumping of the spin with a coherent laser. Contrast is restored by
applying a radio frequency (rf) magnetic field at the spin resonance. The
scheme is sensitive even to rf fields of just a few micro-T. In one case, the
spin resonance behaves exactly as a driven 3-level quantum system (a
lambda-system) with weak damping. In another, the dot exhibits remarkably
strong (67% signal recovery) and narrow (0.34 MHz) spin resonances with

710.4903 | Anonymous Networking amidst Eavesdroppers | The problem of security against timing based traffic analysis in wireless
networks is considered in this work. An analytical measure of anonymity in
eavesdropped networks is proposed using the information theoretic concept of
equivocation. For a physical layer with orthogonal transmitter directed
signaling, scheduling and relaying techniques are designed to maximize
achievable network performance for any given level of anonymity. The network
performance is measured by the achievable relay rates from the sources to
destinations under latency and medium access constraints. In particular,
analytical results are presented for two scenarios:
For a two-hop network with maximum anonymity, achievable rate regions for a
general m x 1 relay are characterized when nodes generate independent Poisson
transmission schedules. The rate regions are presented for both strict and
average delay constraints on traffic flow through the relay.
For a multihop network with an arbitrary anonymity requirement, the problem
of maximizing the sum-rate of flows (network throughput) is considered. A
selective independent scheduling strategy is designed for this purpose, and
using the analytical results for the two-hop network, the achievable throughput
is characterized as a function of the anonymity level. The throughput-anonymity
relation for the proposed strategy is shown to be equivalent to an information
theoretic rate-distortion function.

710.4904 | Density Functional Theory for the Photoionization Dynamics of Uracil | Photoionization dynamics of the RNA base Uracil is studied in the framework
of Density Functional Theory (DFT). The photoionization calculations take
advantage of a newly developed parallel version of a multicentric approach to
the calculation of the electronic continuum spectrum which uses a set of
B-spline radial basis functions and a Kohn-Sham density functional hamiltonian.
Both valence and core ionizations are considered. Scattering resonances in
selected single-particle ionization channels are classified by the symmetry of
the resonant state and the peak energy position in the photoelectron kinetic
energy scale; the present results highlight once more the site specificity of
core ionization processes. We further suggest that the resonant structures
previously characterized in low-energy electron collision experiments are
partly shifted below threshold by the photoionization processes. A critical
evaluation of the theoretical results providing a guide for future experimental
work on similar biosystems.

710.4905 | Distributed Source Coding in the Presence of Byzantine Sensors | The distributed source coding problem is considered when the sensors, or
encoders, are under Byzantine attack; that is, an unknown group of sensors have
been reprogrammed by a malicious intruder to undermine the reconstruction at
the fusion center. Three different forms of the problem are considered. The
first is a variable-rate setup, in which the decoder adaptively chooses the
rates at which the sensors transmit. An explicit characterization of the
variable-rate achievable sum rates is given for any number of sensors and any
groups of traitors. The converse is proved constructively by letting the
traitors simulate a fake distribution and report the generated values as the
true ones. This fake distribution is chosen so that the decoder cannot
determine which sensors are traitors while maximizing the required rate to
decode every value. Achievability is proved using a scheme in which the decoder
receives small packets of information from a sensor until its message can be
decoded, before moving on to the next sensor. The sensors use randomization to
choose from a set of coding functions, which makes it probabilistically
impossible for the traitors to cause the decoder to make an error. Two forms of
the fixed-rate problem are considered, one with deterministic coding and one
with randomized coding. The achievable rate regions are given for both these
problems, and it is shown that lower rates can be achieved with randomized
coding.

710.4906 | Systematics and background suppression in the KATRIN experiment | Recent neutrino mass experiments at Mainz and Troitsk using tritium
beta-decay have reached their sensitivity potential, yielding upper limits of
about 2 eV/c^2 for the electron antineutrino mass. The KArlsruhe TRItium
Neutrino experiment (KATRIN), designed to reach a sensitivity of 0.2 eV/c^2
(90% C.L.), will improve the signal rate by a factor of about 100 with respect
to previous experiments while maintaining the same low background level at an
enhanced energy resolution of 0.93 eV of the spectrometer which is scaled up by
a factor of 10 in linear dimensions. This low background rate can only be
achieved by active and passive reduction of the background components induced
by the spectrometer itself and in the detector region. Furthermore, sources of
systematic errors such as energy losses inside the tritium source or
fluctuations of the energy scale of the spectrometer need to be carefully
controlled and analysed. An overview of KATRIN's method to reduce the

710.4907 | U-Duality and the Compactified Gauss-Bonnet Term | We present the complete toroidal compactification of the Gauss-Bonnet
Lagrangian from D dimensions to (D-n) dimensions. Our goal is to investigate
the resulting action from the point of view of the "U-duality" symmetry
SL(n+1,R) which is present in the tree-level Lagrangian when D-n=3. The
analysis builds upon and extends the investigation of the paper
[arXiv:0706.1183], by computing in detail the full structure of the
compactified Gauss-Bonnet term, including the contribution from the dilaton
exponents. We analyze these exponents using the representation theory of the
Lie algebra sl(n+1,R) and determine which representation seems to be the
relevant one for quadratic curvature corrections. By interpreting the result of
the compactification as a leading term in a large volume expansion of an
SL(n+1,Z)-invariant action, we conclude that the overall exponential dilaton
factor should not be included in the representation structure. As a
consequence, all dilaton exponents correspond to weights of sl(n+1,R), which,
nevertheless, remain on the positive side of the root lattice.

710.491 | Generic Absorbing Transition in Coevolution Dynamics | We study a coevolution voter model on a network that evolves according to the
state of the nodes. In a single update, a link between opposite-state nodes is
rewired with probability $p$, while with probability $1-p$ one of the nodes
takes its neighbor's state. A mean-field approximation reveals an absorbing
transition from an active to a frozen phase at a critical value
$p_c=\frac{\mu-2}{\mu-1}$ that only depends on the average degree $\mu$ of the
network. The approach to the final state is characterized by a time scale that
diverges at the critical point as $\tau \sim |p_c-p|^{-1}$. We find that the
active and frozen phases correspond to a connected and a fragmented network
respectively. We show that the transition in finite-size systems can be seen as
the sudden change in the trajectory of an equivalent random walk at the
critical rewiring rate $p_c$, highlighting the fact that the mechanism behind
the transition is a competition between the rates at which the network and the
state of the nodes evolve.

710.4911 | Social Media as Windows on the Social Life of the Mind | This is a programmatic paper, marking out two directions in which the study
of social media can contribute to broader problems of social science:
understanding cultural evolution and understanding collective cognition. Under
the first heading, I discuss some difficulties with the usual, adaptationist
explanations of cultural phenomena, alternative explanations involving network
diffusion effects, and some ways these could be tested using social-media data.
Under the second I describe some of the ways in which social media could be

five-dimensional D1-D5-P black hole which represent near-horizon microstates in
the limit of large D1-charge. These generalize the corresponding solutions
considered by Gaiotto, Strominger and Yin for the 4-dimensional D0-D4 black
hole. Using U-duality and a 4D-5D connection, we argue that the relevant
configurations are bound states of D1-branes that have expanded through the
Myers effect to form a Kaluza-Klein monopole wrapping the black hole horizon.
We show that these branes experience a magnetic field on their moduli space,
and that the degeneracy of lowest Landau levels reproduces the
Bekenstein-Hawking entropy.

710.4914 | Joule heating in the cooling of magnetized neutron stars | We present 2D simulations of the cooling of neutron stars with strong
magnetic fields (B \geq 10^{13} G). We solve the diffusion equation in axial
symmetry including the state of the art microphysics that controls the cooling
such as slow/fast neutrino processes, superfluidity, as well as possible
heating mechanisms. We study how the cooling curves depend on the the magnetic
field strength and geometry. Special attention is given to discuss the
influence of magnetic field decay. We show that Joule heating effects are very
large and in some cases control the thermal evolution. We characterize the

710.4916 | Impact of interactions on human dynamics | Queueing theory has been recently proposed as a framework to model the heavy
tailed statistics of human activity patterns. The main predictions are the
existence of a power-law distribution for the interevent time of human actions
and two decay exponents $\alpha=1$ and $\alpha=3/2$. Current models lack,
however, a key aspect of human dynamics, i.e. several tasks require, or are
determined by, interactions between individuals. Here we introduce a minimal
queueing model of human dynamics that already takes into account human-human
interactions. To achieve large scale simulations we obtain a coarse-grained
version of the model, allowing us to reach large interevent times and reliable
scaling exponents estimations. Using this we show that the interevent
distribution of interacting tasks exhibit the scaling exponents $\alpha=2$, 3/2
and a series of numerable values between 3/2 and 1. This work demonstrates
that, within the context of queueing models of human dynamics, interactions
change the exponent of the power-law distributed interevent times. Beyond the
study of human dynamics, these results are relevant to systems where the event
of interest consists of the simultaneous occurrence of two (or more) events.

710.4917 | Drip Paintings and Fractal Analysis | It has been claimed [1-6] that fractal analysis can be applied to
unambiguously characterize works of art such as the drip paintings of Jackson
Pollock. This academic issue has become of more general interest following the
recent discovery of a cache of disputed Pollock paintings. We definitively
demonstrate here, by analyzing paintings by Pollock and others, that fractal
criteria provide no information about artistic authenticity. This work has also
led to two new results in fractal analysis of more general scientific
significance. First, the composite of two fractals is not generally scale
invariant and exhibits complex multifractal scaling in the small distance
asymptotic limit. Second the statistics of box-counting and related staircases
provide a new way to characterize geometry and distinguish fractals from
Euclidean objects.

710.4918 | A precise formulation of the third law of thermodynamics | The third law of thermodynamics is formulated precisely: all points of the
state space of zero temperature $\Gamma_0$ are physically adiabatically
inaccessible from the state space of a simple system. In addition to implying
the unattainability of absolute zero in finite time (or "by a finite number of
operations"), it admits as corollary, under a continuity assumption, that all
points of $\Gamma_0$ are adiabatically equivalent. We argue that the third law
is universally valid for all macroscopic systems which obey the laws of quantum
mechanics and/or quantum field theory. We also briefly discuss why a precise
formulation of the third law for black holes remains an open problem.

710.4919 | Harmonic cosmology: How much can we know about a universe before the big
bang? | Quantum gravity may remove classical space-time singularities and thus reveal
what a universe at and before the big bang could be like. In loop quantum
cosmology, an exactly solvable model is available which allows one to address
precise dynamical coherent states and their evolution in such a setting. It is
shown here that quantum fluctuations before the big bang are generically

710.492 | On the quasi-derivation relation for multiple zeta values | Recently, Masanobu Kaneko introduced a conjecture on an extension of the
derivation relation for multiple zeta values. The goal of the present paper is
to present a proof of this conjecture by reducing it to a class of relations
for multiple zeta values studied by Kawashima. In addition, some algebraic
aspects of the quasi-derivation operator $\partial_n^{(c)}$ on $\mathbb{Q}<

710.4922 | Constraining DM properties with SPI | Using the high-resolution spectrometer SPI on board the International
Gamma-Ray Astrophysics Laboratory (INTEGRAL), we search for a spectral line
produced by a dark matter(DM) particle with a mass in the range 40keV < M_DM <
14MeV, decaying in the DM halo of the Milky Way. To distinguish the DM decay
line from numerous instrumental lines found in the SPI background spectrum, we
study the dependence of the intensity of the line signal on the offset of the
SPI pointing from the direction toward the Galactic Centre. After a critical
analysis of the uncertainties of the DM density profile in the inner Galaxy, we
find that the intensity of the DM decay line should decrease by at least a
factor of 3 when the offset from the Galactic Centre increases from 0 to 180
degrees. We find that such a pronounced variation of the line flux across the
sky is not observed for any line, detected with a significance higher than 3
sigma in the SPI background spectrum. Possible DM decay origin is not ruled out
only for the unidentified spectral lines, having low (~3 sigma) significance or
coinciding in position with the instrumental ones. In the energy interval from
20 keV to 7 MeV, we derive restrictions on the DM decay line flux, implied by
the (non-)detection of the DM decay line. For a particular DM candidate, the
sterile neutrino of mass MDM, we derive a bound on the mixing angle.

710.4923 | Di-photon Higgs Decay in SUSY with CP Violation | Physical Higgs particles in the Minimal Supersymmetric Standard Model (MSSM)
with explicit CP violation are CP mixed states. The decay of these Higgs
particles can be analysed to study the CP properties of the MSSM. In the
present work we consider the di-photon channel of the lightest neutral Higgs
boson for this purpose. Compared to earlier studies on effects of
scalar/pseudo-scalar mixing, our analysis also investigates the effect due to
Higgs-sfermion-sfermion couplings along with that of mixing. We find that a
light stop may have a strong impact on the width and Branching Ratio (BR) of
the decay process H1 --> gamma.gamma, whereas other light sparticles have only
little influence. In some regions of the MSSM parameter space with large
CP-violating phase phi-mu ~ 90 deg a light (~ 200 GeV) stop can change the
di-photon BR by more than 50 % compared to the case with heavy (~ 1 TeV) stop
and otherwise same MSSM parameters.

710.4924 | Do Incomplete GUT Multiplets Always Spoil Unification? | We consider a new class of light vectorlike exotics with fractional electric
charge which do not come in complete representations of a grand unified gauge
group, and are nevertheless compatible with gauge coupling unification and
other predictions from Grand Unified Theories. Such states naturally arise in

710.4925 | Differences in Solution Behavior among Four Semiconductor-Binding
Peptides | Recent experiments have identified peptides with adhesion affinity for GaAs
and Si surfaces. Here we use all-atom Monte Carlo (MC) simulations with
implicit solvent to investigate the behavior in aqueous solution of four such
peptides, all with 12 residues. At room temperature, we find that all the four
peptides are largely unstructured, which is consistent with experimental data.
At the same time, we find that one of the peptides is structurally different
and more flexible, compared to the others. This finding points at structural
differences as a possible explanation for differences in adhesion properties
between these peptides. By also analyzing designed mutants of two of the
peptides, an experimental test of this hypothesis is proposed.

710.4926 | Time-resolved investigation of magnetization dynamics of arrays of
non-ellipsoidal nanomagnets with a non-uniform ground state | We have performed time-resolved scanning Kerr microscopy (TRSKM) measurements
upon arrays of square ferromagnetic nano-elements of different size and for a
range of bias fields. The experimental results were compared to micromagnetic
simulations of model arrays in order to understand the non-uniform precessional
dynamics within the elements. In the experimental spectra two branches of
excited modes were observed to co-exist above a particular bias field. Below
the so-called crossover field, the higher frequency branch was observed to
vanish. Micromagnetic simulations and Fourier imaging revealed that modes from
the higher frequency branch had large amplitude at the center of the element
where the effective field was parallel to the bias field and the static
magnetization. Modes from the lower frequency branch had large amplitude near
the edges of the element perpendicular to the bias field. The simulations
revealed significant canting of the static magnetization and the effective
field away from the direction of the bias field in the edge regions. For the
smallest element sizes and/or at low bias field values the effective field was
found to become anti-parallel to the static magnetization. The simulations
revealed that the majority of the modes were de-localized with finite amplitude
throughout the element, while the spatial character of a mode was found to be
correlated with the spatial variation of the total effective field and the
static magnetization state. The simulations also revealed that the frequencies
of the edge modes are strongly affected by the spatial distribution of the
static magnetization state both within an element and within its nearest
neighbors.

Coarse-Grained Hydrophobic-Polar Peptide Model | Folding channels and free-energy landscapes of hydrophobic-polar
heteropolymers are discussed on the basis of a minimalistic off-lattice
coarse-grained model. We investigate how rearrangements of hydrophobic and
polar monomers in a heteropolymer sequence lead to completely different folding
behaviors. Studying three exemplified sequences with the same content of
hydrophobic and polar residues, we can reproduce within this simple model
two-state folding, folding through intermediates, as well as metastability.

conductivity in the effective theory at finite temperature and density, with
emphasis on its dependence on the phase of the Dirac determinant selected
during the evaluation of the effective action. Finally, we discuss the
behavior, under gauge transformations, of the contribution due to the lowest

710.4929 | Phase Separation in Peptide Aggregation Processes - Multicanonical Study
of a Mesoscopic Model | We have performed multicanonical computer simulations of a small system of
short protein-like heteropolymers and found that their aggregation transition
possesses similarities to first-order phase separation processes. Not being a
phase transition in the thermodynamic sense, the observed folding-binding
behavior exhibits fascinating features leading to the conclusion that the
temperature is no suitable control parameter in the transition region. More

710.493 | Extensions of discrete classical orthogonal polynomials beyond the
orthogonality | It is well known that the family of Hahn polynomials
$\{h_n^{\alpha,\beta}(x;N)\}_{n\ge 0}$ is orthogonal with respect to a certain
weight function up to $N$. In this paper we present a factorization for Hahn
polynomials for a degree higher than $N$ and we prove that these polynomials
can be characterized by a $\Delta$-Sobolev orthogonality.
We also present an analogous result for dual-Hahn, Krawtchouk, and Racah
polynomials and give the limit relations between them for all $n\in \XX N_0$.
Furthermore, in order to get this results for the Krawtchouk polynomials we
will get a more general property of orthogonality for Meixner polynomials.

710.4933 | Superlens imaging theory for anisotropic nanostructured metamaterials
with broadband all-angle negative refraction | We show that a metamaterial consisting of aligned metallic nanowires in a
dielectric matrix has strongly anisotropic optical properties. For filling
ratio f<1/2, the composite medium shows two surface plasmon resonances (SPRs):
the transverse and longitudinal SPR with wavelengths lambda_t<lambda_l. For
lambda>lambda_l, the longitudinal SPR, the material exhibits Re epsilon_l<0, Re
epsilon_t>0, relative to the nanowires axis, enabling the achievement of
broadband all-angle negative refraction and superlens imaging. An imaging
theory of superlens made of these media is established. High performance
systems made with Au, Ag or Al nanowires in nanoporous templates are designed
and predicted to work from the infrared up to ultraviolet frequencies.

710.4934 | Spectral analysis of LMC X-2 with XMM/Newton: unveiling the emission
process in the extragalactic Z-source | We present the results of the analysis of an archival observation of LMC X-2
performed with XMM/Newton. The spectra taken by high-precision instruments have
never been analyzed before. We find an X-ray position for the source that is
inconsistent with the one obtained by ROSAT, but in agreement with the Einstein
position and that of the optical counterpart. The correlated spectral and
timing behaviour of the source suggests that the source is probably in the
normal branch of its X-ray color-color diagram. The spectrum of the source can
be fitted with a blackbody with a temperature 1.5 keV plus a disk blackbody at
0.8 keV. Photoelectric absorption from neutral matter has an equivalent
hydrogen column of 4 x 10^{20} cm^{-2}. An emission line, which we identify as
the O VIII Lyman alpha line, is detected, while no feature due to iron is
detected in the spectrum. We argue that the emission of this source can be
straightforwardly interpreted as a sum of the emission from a boundary layer
between the NS and the disc and a blackbody component coming from the disc
itself. Other canonical models that are used to fit Z-sources do not give a
satisfactory fit to the data. The detection of the O VIII emission line (and
the lack of detection of lines in the iron region) can be due to the fact that
the source lies in the Large Magellanic Cloud.

710.4935 | Is Gravitational Lensing by Intercluster Filaments Always Negligible? | Intercluster filaments negligibly contribute to the weak lensing signal in
general relativity (GR), $\gamma_{N}\sim 10^{-4}-10^{-3}$. In the context of
relativistic modified Newtonian dynamics (MOND) introduced by Bekenstein,
however, a single filament inclined by $\approx 45^\circ$ from the line of
sight can cause substantial distortion of background sources pointing towards
the filament's axis ($\kappa=\gamma=(1-A^{-1})/2\sim 0.01$); this is rigorous
for infinitely long uniform filaments, but also qualitatively true for short
filaments ($\sim 30$Mpc), and even in regions where the projected matter
density of the filament is equal to zero. Since galaxies and galaxy clusters
are generally embedded in filaments or are projected on such structures, this
contribution complicates the interpretation of the weak lensing shear map in
the context of MOND. While our analysis is of mainly theoretical interest
providing order-of-magnitude estimates only, it seems safe to conclude that
when modeling systems with anomalous weak lensing signals, e.g. the "bullet
cluster" of Clowe et al., the "cosmic train wreck" of Abell 520 from Mahdavi et
al., and the "dark clusters" of Erben et al., filamentary structures might
contribute in a significant and likely complex fashion. On the other hand, our
predictions of a (conceptual) difference in the weak lensing signal could, in
principle, be used to falsify MOND/TeVeS and its variations.

710.4936 | Dark Matter Caustics in Galaxy Clusters | We interpret the recent gravitational lensing observations of Jee et al.
\cite{Jee} as first evidence for a {\it caustic} ring of dark matter in a
galaxy cluster. A caustic ring unavoidably forms when a cold collisionless flow
falls with net overall rotation in and out of a gravitational potential well.
Evidence for caustic rings of dark matter was previously found in the Milky Way
and other isolated spiral galaxies. We argue that galaxy clusters have at least
one and possibly two or three caustic rings. We calculate the column density
profile of a caustic ring in a cluster and show that it is consistent with the
observations of Jee et al.

710.4937 | Heavy sfermions in SUSY analysis at LHC and ILC | The physics potential of the Large Hadron Collider in combination with the
planned International Linear Collider is discussed for a difficult region of
supersymmetry that is characterized by scalar SUSY particles with masses around
2 TeV. Precision measurements of masses, cross sections and forward-backward
asymmetries allow to determine the fundamental supersymmetric parameters even
if only a small part of the spectrum is accessible. No assumptions on a

This method is essential in order to evaluate the effect of the
momentum-resolved anomalous dimension $\eta(\textbf{p})$ which arises in the
normal phase of this model on the corresponding low-energy single-particle
excitations. As a result, we find important indications pointing to the
existence of a non-Fermi liquid (NFL) regime at temperature $T\to 0$ displaying
a truncated Fermi surface (FS) for a doping range exactly in between the
well-known antiferromagnetic insulating and the $d_{x^2-y^2}$-wave singlet
superconducting phases. This NFL evolves as a function of doping into a
correlated metal with a large FS before the $d_{x^2-y^2}$-wave pairing
susceptibility finally produces the dominant instability in the low-energy
limit.

710.494 | Pore-blockade Times for Field-Driven Polymer Translocation | We study pore blockade times for a translocating polymer of length $N$,
driven by a field $E$ across the pore in three dimensions. The polymer performs
Rouse dynamics, i.e., we consider polymer dynamics in the absence of
hydrodynamical interactions. We find that the typical time the pore remains
blocked during a translocation event scales as $\sim N^{(1+2\nu)/(1+\nu)}/E$,
where $\nu\simeq0.588$ is the Flory exponent for the polymer. In line with our
previous work, we show that this scaling behaviour stems from the polymer
dynamics at the immediate vicinity of the pore -- in particular, the memory
effects in the polymer chain tension imbalance across the pore. This result,
along with the numerical results by several other groups, violates the lower
bound $\sim N^{1+\nu}/E$ suggested earlier in the literature. We discuss why
this lower bound is incorrect and show, based on conservation of energy, that
the correct lower bound for the pore-blockade time for field-driven
translocation is given by $\eta N^{2\nu}/E$, where $\eta$ is the viscosity of
the medium surrounding the polymer.

710.4941 | Ocean Planet or Thick Atmosphere: On the Mass-Radius Relationship for
Solid Exoplanets with Massive Atmospheres | The bulk composition of an exoplanet is commonly inferred from its average
density. For small planets, however, the average density is not unique within
the range of compositions. Variations of a number of important planetary
parameters--which are difficult or impossible to constrain from measurements
alone--produce planets with the same average densities but widely varying bulk
compositions. We find that adding a gas envelope equivalent to 0.1%-10% of the
mass of a solid planet causes the radius to increase 5-60% above its gas-free
value. A planet with a given mass and radius might have substantial water ice
content (a so-called ocean planet) or alternatively a large rocky-iron core and
some H and/or He. For example, a wide variety of compositions can explain the
observed radius of GJ 436b, although all models require some H/He. We conclude
that the identification of water worlds based on the mass-radius relationship
alone is impossible unless a significant gas layer can be ruled out by other
means.

710.4942 | Topology of the Spin-polarized Charge Density in bcc and fcc Iron | We investigate the topology of the spin-polarized charge density in bcc and
fcc iron. While the total spin-density is found to possess the topology of the
non-magnetic prototypical structures, in some cases the spin-polarized
densities are characterized by unique topologies; for example, the
spin-polarized charge densities of bcc and high-spin fcc iron are atypical of
any known for non-magnetic materials. In these cases, the two spin-densities
are correlated: the spin-minority electrons have directional bond paths with
deep minima in the minority density, while the spin-majority electrons fill
these holes, reducing bond directionality. The presence of two distinct spin
topologies suggests that a well-known magnetic phase transition in iron can be
fruitfully reexamined in light of these topological changes. We show that the
two phase changes seen in fcc iron (paramagnetic to low-spin and low-spin to
high-spin) are different. The former follows the Landau symmetry-breaking

imply that the light fermions, the electron and the quarks, $u,d$ and $s$, get

present our results to the masses of these light fermions and as a final result
we can explain why the $s$ quark is heavier than the $u,d$ quarks. This

710.4945 | Degree Bounds for Gr\"obner Bases in Algebras of Solvable Type | We establish doubly-exponential degree bounds for Gr\"obner bases in certain
algebras of solvable type over a field (as introduced by Kandri-Rody and
Weispfenning). The class of algebras considered here includes commutative
polynomial rings, Weyl algebras, and universal enveloping algebras of
finite-dimensional Lie algebras. For the computation of these bounds, we adapt
a method due to Dub\'e based on a generalization of Stanley decompositions. Our
bounds yield doubly-exponential degree bounds for ideal membership and

710.4946 | Small Structures via Thermal Instability of Partially Ionized Plasma. I.
Condensation Mode | (Shortened) Thermal instability of partially ionized plasma is investigated
by linear perturbation analysis. According to the previous studies under the
one fluid approach, the thermal instability is suppressed due to the magnetic
pressure. However, the previous studies did not precisely consider the effect
of the ion-neutral friction, since they did not treat the flow as two fluid
which is composed of ions and neutrals. Then, we revisit the effect of the
ion-neutral friction of the two fluid to the growth of the thermal instability.
According to our study, (1) The instability which is characterized by the mean
molecular weight of neutrals is suppressed via the ion-neutral friction only
when the magnetic field and the friction are sufficiently strong. The
suppression owing to the friction occurs even along the field line. If the
magnetic field and the friction are not so strong, the instability is not
stabilized. (2) The effect of the friction and the magnetic field is mainly
reduction of the growth rate of the thermal instability of weakly ionized
plasma. (3) The effect of friction does not affect the critical wavelength
lambdaF for the thermal instability. This yields that lambdaF of the weakly
ionized plasma is not enlarged even when the magnetic field exists. We insist
that the thermal instability of the weakly ionized plasma in the magnetic field
can grow up even at the small length scale where the instability under the
assumption of the one fluid plasma can not grow owing to the stabilization by
the magnetic field. (4) The wavelength of the maximum growth rate of the
instability shifts shortward according to the decrement of the growth rate,
because the friction is effective at rather larger scale. Therefore, smaller
structures are expected to appear than those without the ion-neutral friction.

710.4947 | Physics at a future Neutrino Factory and super-beam facility | The conclusions of the Physics Working Group of the international scoping
study of a future Neutrino Factory and super-beam facility (the ISS) are
presented. The ISS was carried by the international community between NuFact05,
(the 7th International Workshop on Neutrino Factories and Superbeams,
Laboratori Nazionali di Frascati, Rome, June 21-26, 2005) and NuFact06 (Ivine,
California, 24{30 August 2006). The physics case for an extensive experimental
programme to understand the properties of the neutrino is presented and the
role of high-precision measurements of neutrino oscillations within this
programme is discussed in detail. The performance of second generation
super-beam experiments, beta-beam facilities, and the Neutrino Factory are
evaluated and a quantitative comparison of the discovery potential of the three
classes of facility is presented. High-precision studies of the properties of
the muon are complementary to the study of neutrino oscillations. The Neutrino
Factory has the potential to provide extremely intense muon beams and the

710.495 | Titan's rotation: A 3-dimensional theory | We study the forced rotation of Titan seen as a rigid body at the equilibrium
Cassini state, involving the spin-orbit synchronization. We used both the
analytical and the numerical ways. We analytically determined the equilibrium
positions and the frequencies of the 3 free librations around it, while a
numerical integration associated to frequency analysis gave us a more
synthetic, complete theory, where the free solution split from the forced one.
We find a mean obliquity of 2.2 arcmin and the fundamental frequencies of the
free librations of about 2.0977, 167.4883, and 306.3360 years. Moreover, we

formalism in the context of Whitehead groups of non-commutative Iwasawa
