710.3253 | Two Paradoxes of the Existence of electric Charge | Electromagnetic waves propagate with the speed of light. The reason is that
electrostatic fields as well as magnetic fields propagate with this speed. Both
types of objects, waves as well as static fields contain and transport energy.
Consequently it is possible to calculate how much energy and how much energy
density a source of a field emits into the space - and the calculation shows
that this energy is not zero, for elementary particles as well as for
macroscopic spheres. The calculation is presented in this article.
This leads to a principle problem not being answered up to now: From where
does the static charge obtain the energy, which it emits permantently? But the
paradox has a second aspect: If we follow the trace of a specified element of
volume containing an electric field on its way through the space, we will
notice that its contents of field energy decreases during time. But where does
this effluent energy go?

710.3254 | Influence of hydrodynamic interactions on lane formation in oppositely
charged driven colloids | The influence of hydrodynamic interactions on lane formation of oppositely
charged driven colloidal suspensions is investigated using Brownian dynamics
computer simulations performed on the Rotne-Prager level of the mobility
tensor. Two cases are considered, namely sedimentation and electrophoresis. In
the latter case the Oseen contribution to the mobility tensor is screened due
to the opposite motion of counterions. The simulation results are compared to
that resulting from simple Brownian dynamics where hydrodynamic interactions
are neglected. For sedimentation, we find that hydrodynamic interactions
strongly disfavor laning. In the steady-state of lanes, a macroscopic phase
separation of lanes is observed. This is in marked contrast to the simple
Brownian case where a finite size of lanes was obtained in the steady-state.
For strong Coulomb interactions between the colloidal particles a lateral
square lattice of oppositely driven lanes is stable similar to the simple
Brownian dynamics. In an electric field, on the other hand, the behavior is
found in qualitative and quantitative accordance with the case of neglected
hydrodynamics.

710.3256 | Statistical physics of social dynamics | Statistical physics has proven to be a very fruitful framework to describe
phenomena outside the realm of traditional physics. The last years have
witnessed the attempt by physicists to study collective phenomena emerging from
the interactions of individuals as elementary units in social structures. Here
we review the state of the art by focusing on a wide list of topics ranging
from opinion, cultural and language dynamics to crowd behavior, hierarchy
formation, human dynamics, social spreading. We highlight the connections
between these problems and other, more traditional, topics of statistical
physics. We also emphasize the comparison of model results with empirical data
from social systems.

710.3257 | Acceleration of heavy and light particles in turbulence: comparison
between experiments and direct numerical simulations | We compare experimental data and numerical simulations for the dynamics of
inertial particles with finite density in turbulence. In the experiment,
bubbles and solid particles are optically tracked in a turbulent flow of water
using an Extended Laser Doppler Velocimetry technique. The probability density
functions (PDF) of particle accelerations and their auto-correlation in time
are computed. Numerical results are obtained from a direct numerical simulation
in which a suspension of passive pointwise particles is tracked, with the same
finite density and the same response time as in the experiment. We observe a
good agreement for both the variance of acceleration and the autocorrelation
timescale of the dynamics; small discrepancies on the shape of the acceleration
PDF are observed. We discuss the effects induced by the finite size of the
particles, not taken into account in the present numerical simulations.

710.3258 | Worst-case optimal approximation algorithms for maximizing triplet
consistency within phylogenetic networks | This article concerns the following question arising in computational
evolutionary biology. For a given subclass of phylogenetic networks, what is
the maximum value of 0 <= p <= 1 such that for every input set T of rooted
triplets, there exists some network N(T) from the subclass such that at least
p|T| of the triplets are consistent with N(T)? Here we prove that the set
containing all triplets (the full triplet set) in some sense defines p, and
moreover that any network N achieving fraction p' for the full triplet set can
be converted in polynomial time into an isomorphic network N'(T) achieving >=
p' for an arbitrary triplet set T. We demonstrate the power of this result for
the field of phylogenetics by giving worst-case optimal algorithms for level-1

710.3259 | Continuous variable quantum teleportation with sculptured and noisy
non-Gaussian resources | We investigate continuous variable (CV) quantum teleportation using relevant
classes of non-Gaussian states of the radiation field as entangled resources.
First, we introduce the class two-mode squeezed symmetric superposition of Fock
states, including finite truncations of twin-beam Gaussian states as special
realizations. These states depend on a set of free independent parameters that
can be adjusted for the optimization of teleportation protocols, with an
enhancement of the success probability of teleportation both for coherent and
Fock input states. We show that the optimization procedure reduces the
entangled resources to truncated twin beam states, which thus represents an
optimal class of non-Gaussian resources for quantum teleportation. We then
introduce a further class of two-mode non-Gaussian entangled resources, in the
form of squeezed cat-like states. We analyze the performance and the properties
of such states when optimized for (CV) teleportation, and compare them to the
optimized squeezed Bell-like states introduced in a previous work
\cite{CVTelepNoi}. We discuss how optimal resources for teleportation are
characterized by a suitable balance of entanglement content and squeezed vacuum
affinity. We finally investigate the effects of thermal noise on the efficiency
of quantum teleportation. To this aim, a convenient framework is to describe
noisy entangled resources as linear superpositions of non-Gaussian state and
thermal states. Although the presence of the thermal component strongly reduces
the teleportation fidelity, noisy non-Gaussian states remain preferred
resources when compared to noisy twin-beam Gaussian states.

710.326 | YbRh2Si2: Quantum tricritical behavior in itinerant electron systems | We propose that proximity of the first-order transition manifested by the
quantum tricritical point (QTCP) explains non-Fermi-liquid properties of
YbRh2Si2. Here, at the QTCP, a continuous phase transition changes into first
order at zero temperature. The non-Fermi-liquid behaviors of YbRh2Si2 are
puzzling in two aspects; diverging ferromagnetic susceptibility at the
antiferromagnetic transition and unconventional power-law dependence in

over a p-adic field | We decompose the restriction of ramified principal series representations of
the $p$-adic group $\mathrm{GL}(3,\mathrm{k})$ to its maximal compact subgroup
$K=\mathrm{GL}(3,\mathscr{R})$. Its decomposition is dependent on the degree of
ramification of the inducing characters and can be characterized in terms of

710.3264 | Nanodroplets on rough hydrophilic and hydrophobic surfaces | We present results of Molecular Dynamics (MD) calculations on the behavior of
liquid nanodroplets on rough hydrophobic and hydrophilic solid surfaces. On
hydrophobic surfaces, the contact angle for nanodroplets depends strongly on
the root mean square roughness amplitude, but it is nearly independent of the
fractal dimension of the surface. Since increasing the fractal dimension
increases the short-wavelength roughness, while the long-wavelength roughness
is almost unchanged, we conclude that for hydrophobic interactions the
short-wavelength (atomistic) roughness is not very important. We show that the
nanodroplet is in a Cassie-like state. For rough hydrophobic surfaces, there is
no contact angle hysteresis due to strong thermal fluctuations, which occur at
the liquid-solid interface on the nanoscale. On hydrophilic surfaces, however,
there is strong contact angle hysteresis due to higher energy barrier. These
findings may be very important for the development of artificially biomimetic
superhydrophobic surfaces.

frictions: a Gaussian white noise accounting for the friction with the
substrate, and a white shot noise characterized by a collisional friction
simulating the adsorbate-adsorbate collisions. The broadenings undergone by the
quasielastic peak are found to be in very good agreement with the experimental
data reported at two surface temperatures 200 and 300 K.

710.3268 | Googling Social Interactions: Web Search Engine Based Social Network
Construction | Social network analysis has long been an untiring topic of sociology.
However, until the era of information technology, the availability of data,
mainly collected by the traditional method of personal survey, was highly
limited and prevented large-scale analysis. Recently, the exploding amount of
automatically generated data has completely changed the pattern of research.
For instance, the enormous amount of data from so-called high-throughput
biological experiments has introduced a systematic or network viewpoint to
traditional biology. Then, is "high-throughput" sociological data generation
possible? Google, which has become one of the most influential symbols of the
new Internet paradigm within the last ten years, might provide torrents of data
sources for such study in this (now and forthcoming) digital era. We
investigate social networks between people by extracting information on the Web
and introduce new tools of analysis of such networks in the context of
statistical physics of complex systems or socio-physics. As a concrete and
illustrative example, the members of the 109th United States Senate are
analyzed and it is demonstrated that the methods of construction and analysis
are applicable to various other weighted networks.

710.3269 | Differential equation approximations for Markov chains | We formulate some simple conditions under which a Markov chain may be
approximated by the solution to a differential equation, with quantifiable
error probabilities. The role of a choice of coordinate functions for the
Markov chain is emphasised. The general theory is illustrated in three
examples: the classical stochastic epidemic, a population process model with
fast and slow variables, and core-finding algorithms for large random
hypergraphs.

according to a braneworld observer. Extending on our previous work, we
numerically compute the spectrum of excitations of fermion modes localised on
the brane and boundary, in terms of the momentum $k$ along the brane
dimensions. We find that the spectrum depends strongly on collision velocity
and fermion-scalar coupling. Also, high-momentum modes tend to ``fall off'' the
kinks and become delocalised radiation.

710.3273 | Complex Fundamental Diagram of Traffic Flow in the Deep Lefortovo Tunnel
(Moscow) | The fundamental diagram for tunnel traffic is constructed based on the
empirical data collected during the last two years in the deep long branch of
the Lefortovo tunnel located on the 3$^\text{rd}$ circular highway of Moscow.
This tunnel of length 3 km is equipped with a dense system of stationary
radiodetetors distributed uniformly along it chequerwise at spacing of 60 m.
The data were averaged over 30 s. Each detector measures three characteristics
of the vehicle ensemble; the flow rate, the car velocity, and the occupancy for
three lanes individually. The conducted analysis reveals an original complex
structure of the fundamental diagram.

710.3274 | Dilepton measurements with HADES | HADES is the only operating dielectron spectrometer in the energy regime 1-2
AGeV. The physics program aims at a systematic investigation of dielectron
production in heavy ion as well as elementary and pion-induced reactions.
This contribution highlights recent results on electron pair production in
C12+C12 collisions at an incident energy of 2 AGeV with HADES. The measured
pair production probabilities span over five orders of magnitude. Dalitz decays
of pi0 and eta account for all the yield up to 0.15 GeV/c2, but for only about
50% above this invariant mass. The excess yield compared to the hadronic
cocktail between the pi0-Dalitz and the rho/omega invariant-mass region is in
agreement with the former DLS result if one assumes that it scales with beam

710.3275 | Search for single top production using multivariate analyses at CDF | This article reports on recent searches for single-top-quark production by
the CDF collaboration at the Tevatron using a data set that corresponds to an
integrated luminosity of 955 fb^-1. Three different analyses techniques are
employed, one using likelihood discriminants, one neural networks and one
matrix elements. The sensitivity to single-top production at the rate predicted
by the standard model ranges from 2.1 to 2.6 sigma. While the first two
analyses observe a deficit of single-top like events compared to the
expectation, the matrix element method observes an excess corresponding to a
background fluctuation of 2.3 sigma. The null results of the likelihood and
neural network analyses translate in upper limits on the cross section of 2.6
pb for the t-channel production mode and 3.7 pb for the s-channel mode at the
95% C.L. The matrix element result corresponds to a measurement of
2.7^{+1.5}_{-1.3} pb for the combined t- and s-channel single-top cross
section. In addition, CDF has searched for non-standard model production of
single-top-quarks via the s-channel exchange of a heavy W' boson. No signal of
this process is found resulting in lower mass limits of 760 GeV/c^2 in case the
mass of the right-handed neutrino is smaller than the mass of the right-handed
W' or 790 GeV/c^2 in the opposite case.

710.3276 | Group field theory as the microscopic description of the quantum
spacetime fluid: a new perspective on the continuum in quantum gravity | We introduce the group field theory (GFT) formalism for non-perturbative
quantum gravity, and present it as a potential unifying framework for several
other quantum gravity approaches, i.e. loop quantum gravity and simplicial
quantum gravity ones. We then argue in favor of and present in detail what we
believe is a new GFT perspective on the emergence of continuum spacetime from
discrete quantum structures, based on the idea of quantum space as a condensed
matter system. We put forward a more specific, albeit still very much
tentative, proposal for the relevant phase of the GFT corresponding to the
continuum: a Bose-Einstein condensate of GFT quanta. Finally, we sketch how the

710.3278 | Package models and the information crisis of prebiotic evolution | The coexistence between different types of templates has been the choice
solution to the information crisis of prebiotic evolution, triggered by the
finding that a single RNA-like template cannot carry enough information to code
for any useful replicase. In principle, confining $d$ distinct templates of
length $L$ in a package or protocell, whose survival depends on the coexistence
of the templates it holds in, could resolve this crisis provided that $d$ is
made sufficiently large. Here we review the prototypical package model of
Niesert et al. 1981 which guarantees the greatest possible region of viability
of the protocell population, and show that this model, and hence the entire
package approach, does not resolve the information crisis. This is so because
to secure survival the total information content of the protocell, $Ld$, must
tend to a constant value that depends only on the spontaneous error rate per
nucleotide of the template replication mechanism. As a result, an increase of

710.3279 | Resource Allocation for Delay Differentiated Traffic in Multiuser OFDM
Systems | Most existing work on adaptive allocation of subcarriers and power in
multiuser orthogonal frequency division multiplexing (OFDM) systems has focused
on homogeneous traffic consisting solely of either delay-constrained data
(guaranteed service) or non-delay-constrained data (best-effort service). In
this paper, we investigate the resource allocation problem in a heterogeneous
multiuser OFDM system with both delay-constrained (DC) and
non-delay-constrained (NDC) traffic. The objective is to maximize the sum-rate
of all the users with NDC traffic while maintaining guaranteed rates for the
users with DC traffic under a total transmit power constraint. Through our
analysis we show that the optimal power allocation over subcarriers follows a
multi-level water-filling principle; moreover, the valid candidates competing
for each subcarrier include only one NDC user but all DC users. By converting
this combinatorial problem with exponential complexity into a convex problem or
showing that it can be solved in the dual domain, efficient iterative
algorithms are proposed to find the optimal solutions. To further reduce the
computational cost, a low-complexity suboptimal algorithm is also developed.
Numerical studies are conducted to evaluate the performance the proposed
algorithms in terms of service outage probability, achievable transmission rate
pairs for DC and NDC traffic, and multiuser diversity.

710.328 | Generalized Entropy and Transport Coefficients of Hadronic Matter | We use the generalized entropy four-current of the Muller-Israel-Stewart
(MIS) theory of relativistic dissipative fluids to obtain information about
fluctuations around equilibrium. This allows one to compute the non-classical
coefficients of the entropy 4-flux in terms of the equilibrium distribution
functions. The Green-Kubo formulae are used to compute the classical or

710.3282 | Condensation of cloud microdroplets in homogeneous isotropic turbulence | The growth by condensation of small water droplets in a three-dimensional
homogeneous isotropic turbulent flow is considered. Within a simple model of
advection and condensation, the dynamics and growth of millions of droplets are
integrated. A droplet-size spectra broadening is obtained and it is shown to
increase with the Reynolds number of turbulence, by means of two series of
direct numerical simulations at increasing resolution. This is a key point
towards a proper evaluation of the effects of turbulence for condensation in
warm clouds, where the Reynolds numbers typically achieve huge values. The
obtained droplet-size spectra broadening as a function of the Reynolds number
is shown to be consistent with dimensional arguments. A generalization of this
expectation to Reynolds numbers not accessible by DNS is proposed, yielding
upper and lower bounds to the actual size-spectra broadening. A further DNS
matching the large scales of the system suggests consistency of the picture
drawn, while additional effort is needed to evaluate the impact of this effect
for condensation in more realistic cloud conditions.

710.3285 | Nontraditional Scoring of C-tests | In C-tests the hypothesis of items local independence is violated, which
doesn't permit to consider them as real tests. It is suggested to determine the
distances between separate C-test items (blanks) and to combine items into
clusters. Weights, inversely proportional to the number of items in
corresponding clusters, are assigned to items. As a result, the C-test
structure becomes similar to the structure of classical tests, without
violation of local independence hypothesis.

710.3286 | Lateral migration of a 2D vesicle in unbounded Poiseuille flow | The migration of a suspended vesicle in an unbounded Poiseuille flow is
investigated numerically in the low Reynolds number limit. We consider the
situation without viscosity contrast between the interior of the vesicle and
the exterior. Using the boundary integral method we solve the corresponding
hydrodynamic flow equations and track explicitly the vesicle dynamics in two
dimensions. We find that the interplay between the nonlinear character of the
Poiseuille flow and the vesicle deformation causes a cross-streamline migration
of vesicles towards the center of the Poiseuille flow. This is in a marked
contrast with a result [L.G. Leal, Ann. Rev. Fluid Mech. 12,
435(1980)]according to which the droplet moves away from the center (provided
there is no viscosity contrast between the internal and the external fluids).
The migration velocity is found to increase with the local capillary number
(defined by the time scale of the vesicle relaxation towards its equilibrium
shape times the local shear rate), but reaches a plateau above a certain value
of the capillary number. This plateau value increases with the curvature of the
parabolic flow profile. We present scaling laws for the migration velocity.

710.3287 | On the performance of FDR control: Constraints and a partial solution | The False Discovery Rate (FDR) paradigm aims to attain certain control on
Type I errors with relatively high power for multiple hypothesis testing. The
Benjamini--Hochberg (BH) procedure is a well-known FDR controlling procedure.
Under a random effects model, we show that, in general, unlike the FDR, the
positive FDR (pFDR) of the BH procedure cannot be controlled at an arbitrarily
low level due to the limited evidence provided by the observations to separate
false and true nulls. This results in a criticality phenomenon, which is
characterized by a transition of the procedure's power from being positive to
asymptotically 0 without any reduction in the pFDR, once the target FDR control
level is below a positive critical value. To address the constraints on the
power and pFDR control imposed by the criticality phenomenon, we propose a
procedure which applies BH-type procedures at multiple locations in the domain
of $p$-values. Both analysis and simulations show that the proposed procedure
can attain substantially improved power and pFDR control.

710.3289 | Transient magnetotransport through a quantum wire | We consider an ideal parabolic quantum wire in a perpendicular magnetic
field. A simple Gaussian shaped scattering potential well or hill is flashed
softly on and off with its maximum at $t=0$, mimicking a temporary broadening
or narrowing of the wire. By an extension of the Lippmann-Schwinger formalism
to time-dependent scattering potentials we investigate the effects on the
continuous current that is driven through the quantum wire with a vanishingly
small forward bias. The Lippmann-Schwinger approach to the scattering process

710.3292 | Continuous Abelian Sandpile Model in Two Dimensional Lattice | We define a new version of sandpile model which is very similar to Abelian
Sandpile Model (ASM), but the height variables are continuous ones. With the
toppling rule we define in our model, we show that the model can be mapped to
ASM, so the general properties of the two models are identical. Yet the new

710.3293 | Electronic transitions in Rydberg Matter as the source of the
unidentified infrared bands (UIR) observed in interstellar space | Rydberg Matter (RM) theory is previously shown to give good agreement with
the unidentified infrared bands (UIR, UIB) that are observed in emission from
many objects in space. From stimulated emission studies in RM, a slightly
simpler theoretical model is found that describes the transitions giving the
UIR bands better. The general theory for RM was recently shown to be very
accurate using rotational spectroscopy to observe several types of RM clusters
(Mol. Phys. 105 (2007) 933). Two different large studies of UIR are now
interpreted with the improved model. High-resolution UIR observations by
Beintema et al. are interpreted as transitions from high levels n = 40 - 80
down to levels n = 5 - 12 in the final state. The upper level quantum numbers
for the observed bands agree well with those found in experiments. The
stationary UIR bands at 3.3 and 11.3 micrometer are due to deexcitation n = 9
-> 5 and 9 -> 7 of Rydberg species through stimulated emission. The other UIR
bands vary considerably in wavelength in different environments and even with
time as seen in numerous observational studies. Their great variability is
difficult to model by the commonly used PAH model, but is a natural consequence
of the varying excitation state of RM.

by scattering. In scattering materials, such as powders, disordered
metamaterials or biological tissue, multiple scattering on sub-wavelength
particles makes light diffuse. Recently, we showed that it is possible to
construct a wavefront that focuses through a solid, strongly scattering object.
The focusing wavefront uniquely matches a certain configuration of the
particles in the medium. To focus light through a turbid liquid or living
tissue, it is necessary to dynamically adjust the wavefront as the particles in
the medium move. Here we present three algorithms for constructing a wavefront
that focuses through a scattering medium. We analyze the dynamic behavior of
these algorithms and compare their sensitivity to measurement noise. The
algorithms are compared both experimentally and using numerical simulations.
The results are in good agreement with an intuitive model, which may be used to
develop dynamic diffusion compensators with applications in, for example, light
delivery in human tissue.

710.3297 | Computing the optimal protocol for finite-time processes in stochastic
thermodynamics | Asking for the optimal protocol of an external control parameter that
minimizes the mean work required to drive a nano-scale system from one
equilibrium state to another in finite time, Schmiedl and Seifert ({\it Phys.
Rev. Lett.} {\bf 98}, 108301 (2007)) found the Euler-Lagrange equation to be a
non-local integro-differential equation of correlation functions. For two
linear examples, we show how this integro-differential equation can be solved
analytically. For non-linear physical systems we show how the optimal protocol
can be found numerically and demonstrate that there may exist several distinct

model | We study the stability of layered structures in a variational model for
diblock copolymer-homopolymer blends. The main step consists of calculating the
first and second derivative of a sharp-interface Ohta-Kawasaki energy for
straight mono- and bilayers. By developing the interface perturbations in a
Fourier series we fully characterise the stability of the structures in terms
of the energy parameters.
In the course of our computations we also give the Green's function for the
Laplacian on a periodic strip and explain the heuristic method by which we
found it.

710.3299 | Many body physics and the capacity of quantum channels with memory | In most studies of the capacity of quantum channels, it is assumed that the
errors in each use of the channel are independent. However, recent work has
begun to investigate the effects of memory or correlations in the error, and
has led to suggestions that there can be interesting non-analytic behaviour in
the capacity of such channels. In a previous paper we pursued this issue by
connecting the study of channel capacities under correlated error to the study
of critical behaviour in many-body physics. This connection enables the use of
techniques from many-body physics to either completely solve or understand
qualitatively a number of interesting models of correlated error with analogous
behaviour to associated many-body systems. However, in order for this approach
to work rigorously, there are a number of technical properties that need to be
established for the lattice systems being considered. In this article we

| quant-ph | in most studies of the capacity of quantum channels it is assumed that the errors in each use of the channel are independent however recent work has begun to investigate the effects of memory or correlations in the error and has led to suggestions that there can be interesting nonanalytic behaviour in the capacity of such channels in a previous paper we pursued this issue by connecting the study of channel capacities under correlated error to the study of critical behaviour in manybody physics this connection enables the use of techniques from manybody physics to either completely solve or understand qualitatively a number of interesting models of correlated error with analogous behaviour to associated manybody systems however in order for this approach to work rigorously there are a number of technical properties that need to be established for the lattice systems being considered in this article we discuss these properties in detail and establish them for some classes of manybody system | [['in', 'most', 'studies', 'of', 'the', 'capacity', 'of', 'quantum', 'channels', 'it', 'is', 'assumed', 'that', 'the', 'errors', 'in', 'each', 'use', 'of', 'the', 'channel', 'are', 'independent', 'however', 'recent', 'work', 'has', 'begun', 'to', 'investigate', 'the', 'effects', 'of', 'memory', 'or', 'correlations', 'in', 'the', 'error', 'and', 'has', 'led', 'to', 'suggestions', 'that', 'there', 'can', 'be', 'interesting', 'nonanalytic', 'behaviour', 'in', 'the', 'capacity', 'of', 'such', 'channels', 'in', 'a', 'previous', 'paper', 'we', 'pursued', 'this', 'issue', 'by', 'connecting', 'the', 'study', 'of', 'channel', 'capacities', 'under', 'correlated', 'error', 'to', 'the', 'study', 'of', 'critical', 'behaviour', 'in', 'manybody', 'physics', 'this', 'connection', 'enables', 'the', 'use', 'of', 'techniques', 'from', 'manybody', 'physics', 'to', 'either', 'completely', 'solve', 'or', 'understand', 'qualitatively', 'a', 'number', 'of', 'interesting', 'models', 'of', 'correlated', 'error', 'with', 'analogous', 'behaviour', 'to', 'associated', 'manybody', 'systems', 'however', 'in', 'order', 'for', 'this', 'approach', 'to', 'work', 'rigorously', 'there', 'are', 'a', 'number', 'of', 'technical', 'properties', 'that', 'need', 'to', 'be', 'established', 'for', 'the', 'lattice', 'systems', 'being', 'considered', 'in', 'this', 'article', 'we', 'discuss', 'these', 'properties', 'in', 'detail', 'and', 'establish', 'them', 'for', 'some', 'classes', 'of', 'manybody', 'system']] | [-0.14149954203539383, 0.10112822874339286, -0.09207769672629303, 0.06834177097655625, -0.024725454853650946, -0.14452146017715706, 0.06692666123890151, 0.36032350090627346, -0.26888447854543535, -0.28281353819560007, 0.11307473399066106, -0.27910898407481566, -0.18769773360781417, 0.1987164422424267, -0.08117569297239739, 0.10112759701528742, 0.03998318981373486, 0.045212918133272426, -0.06985114299784767, -0.25359123000030565, 0.3529167732958514, 0.05067603446193247, 0.2376627350654106, 0.07090419652164619, 0.010256943281346596, -0.018825561104643142, -0.019744386156422218, 0.03416134438460103, -0.14879086820088921, 0.12351723526668104, 0.2832211025925514, 0.08035259187305223, 0.2853995614181857, -0.43389406977857675, -0.24889378136266832, 0.11643273533778901, 0.15380730560651015, 0.12367238501746276, -0.04782541153188911, -0.24537249243245546, 0.07689143100649304, -0.17586990071298636, -0.13396089674719835, -0.0786797000754694, 0.0184240228733661, 0.016638136880981348, -0.2303742903070698, 0.06505726495329638, 0.07582466297252219, 0.04355945962810923, -4.034481077854123e-05, -0.09048886679514942, 0.07691073662641904, 0.17634230987776234, 0.09132722289278317, 0.007643275266594213, 0.05090203229337931, -0.1566706272738737, -0.13230747805896753, 0.38102449665875726, -0.005011801153091679, -0.19904322784628303, 0.23850066725291913, -0.1441530921346051, -0.16745980592120602, 0.0974039314777492, 0.19826060937289497, 0.058031432851223475, -0.19245114896781973, 0.0807072092375504, -0.007305046202186842, 0.14880556910897472, 0.003986050756590337, 0.12174800298356028, 0.19124955092759235, 0.15891690081945672, 0.03959688699590216, 0.16179501182422829, -0.03032503067859252, -0.12371161329901274, -0.2754133892540606, -0.1601254065630969, -0.17893746621351433, 0.05590979800623211, 0.02167511941964148, -0.12978201256544322, 0.39552596625611647, 0.22977695035059814, 0.18720925473232078, 0.012170144591064, 0.2534687594851907, 0.09285470301296955, 0.05343731567270834, 0.056785577254497115, 0.24646012636168385, 0.1420092584047559, 0.08194572927997164, -0.21863524324726313, 0.08180778060088177, 0.008402982339124131] |

instabilities in DC voltage-biased nanoelectromechanical single-electron
tunneling (NEM-SET) devices. We show that initially irregular (quasi-periodic)
oscillations, that occur as a result of the simultaneous self-excitation of
several mechanical modes with incommensurable frequencies, self-organize into
periodic oscillations with a frequency corresponding to the eigenfrequency of
one of the unstable modes. This effect demonstrates that a local probe can
selectively excite global vibrations of extended objects.

710.3305 | Automatic Methods for Analyzing Non-Repudiation Protocols with an Active
Intruder | Non-repudiation protocols have an important role in many areas where secured
transactions with proofs of participation are necessary. Formal methods are
clever and without error, therefore using them for verifying such protocols is
crucial. In this purpose, we show how to partially represent non-repudiation as
a combination of authentications on the Fair Zhou-Gollmann protocol. After
discussing its limits, we define a new method based on the handling of the
knowledge of protocol participants. This method is very general and is of
natural use, as it consists in adding simple annotations, like for
authentication problems. The method is very easy to implement in tools able to
handle participants knowledge. We have implemented it in the AVISPA Tool and
analyzed the optimistic Cederquist-Corin- Dashti protocol, discovering two
unknown attacks. This extension of the AVISPA Tool for handling non-repudiation

710.3306 | Light-mass Bragg cavity polaritons in planar quantum dot lattices | The exciton-polariton modes of a quantum dot lattice embedded in a planar
optical cavity are theoretically investigated. Umklapp terms, in which an
exciton interacts with many cavity modes differing by reciprocal lattice
vectors, appear in the Hamiltonian due to the periodicity of the dot lattice.
We focus on Bragg polariton modes obtained by tuning the exciton and the cavity
modes into resonance at high symmetry points of the Brillouin Zone. Depending
on the microcavity design these polaritons modes at finite in-plane momentum
can be guided and can have long lifetimes. Moreover, their effective mass can
be extremely small, of the order of $10^{-8} m_0$ ($m_0$ is the bare electron
mass), and they constitute the lightest exciton-like quasi-particles in solids.

electroweak and supersymmetric effects | The high accuracy envisaged for future measurements of W-boson production at
hadron colliders has to be matched by precise theoretical predictions. We study
the impact of electroweak radiative corrections on W-boson production cross
sections and differential distributions at the Tevatron and at the LHC. In
particular, we include photon-induced processes, which contribute at O(alpha),
and leading radiative corrections beyond O(alpha) in the high-energy Sudakov
regime and from multi-photon final-state radiation. We furthermore present the
calculation of the complete supersymmetric next-to-leading-order electroweak
and QCD corrections to W-boson hadroproduction within the MSSM. The
supersymmetric corrections turn out to be negligible in the vicinity of the W
resonance in general, reaching the percent level only at high lepton transverse
momentum and for specific choices of the supersymmetric parameters.

710.331 | Two-parameter model predictions and theta-point crossover for
linear-polymer solutions | We consider the first few virial coefficients of the osmotic pressure, the
radius of gyration, the hydrodynamic radius, and the end-to-end distance for a
monodisperse polymer solution. We determine the corresponding two-parameter
model functions which parametrize the crossover between the good-solvent and
the ideal-chain behavior. These results allow us to predict the osmotic

710.3311 | Global firing induced by network disorder in ensembles of active
rotators | We study the influence of repulsive interactions on an ensemble of coupled
excitable rotators. We find that a moderate fraction of repulsive interactions
can trigger global firing of the ensemble. The regime of global firing,
however, is suppressed in sufficiently large systems if the network of
repulsive interactions is fully random, due to self-averaging in its degree
distribution. We thus introduce a model of partially random networks with a
broad degree distribution, where self-averaging due to size growth is absent.
In this case, the regime of global firing persists for large sizes. Our results
extend previous work on the constructive effects of diversity in the collective
dynamics of complex systems.

710.3313 | On the gamma-ray emission of Type Ia Supernovae | A multi-dimension, time-dependent Monte Carlo code is used to compute sample
gamma-ray spectra to explore whether unambiguous constraints could be obtained
from gamma-ray observations of Type Ia supernovae. Both spherical and
aspherical geometries are considered and it is shown that moderate departures
from sphericity can produce viewing-angle effects that are at least as
significant as those caused by the variation of key parameters in
one-dimensional models. Thus gamma-ray data could in principle carry some
geometrical information, and caution should be applied when discussing the
value of gamma-ray data based only on one-dimensional explosion models. In
light of the limited sensitivity of current gamma-ray observatories, the
computed theoretical spectra are studied to revisit the issue of whether useful
constraints could be obtained for moderately nearby objects. The most useful
gamma-ray measurements are likely to be of the light curve and time-dependent

710.3314 | Pulsational pair instability as an explanation for the most luminous
supernovae | The extremely luminous supernova SN 2006gy challenges the traditional view
that the collapse of a stellar core is the only mechanism by which a massive
star makes a supernova, because it seems too luminous by more than a factor of
ten. Here we report that the brightest supernovae in the modern Universe arise
from collisions between shells of matter ejected by massive stars that undergo
an interior instability arising from the production of electron-positron pairs.
This "pair instability" leads to explosive burning that is insufficient to
unbind the star, but ejects many solar masses of the envelope. After the first
explosion, the remaining core contracts and searches for a stable burning
state. When the next explosion occurs, several solar masses of material are
again ejected, which collide with the earlier ejecta. This collision can
radiate 1E50 erg of light, about a factor of ten more than an ordinary
supernova. Our model is in good agreement with the observed light curve for SN
2006gy and also shows that some massive stars can produce more than one
supernova-like outburst.

710.3315 | Can the Quantum Measurement Problem be resolved within the framework of
Schroedinger Dynamics and Quantum Probability? | We provide an affirmative answer to the question posed in the title. Our
argument is based on a treatment of the Schroedinger dynamics of the composite
of a quantum microsystem, S, and a macroscopic measuring apparatus, I,
consisting of N interacting particles. The pointer positions of this apparatus
are represented by orthogonal subspaces of its representative Hilbert space
that are simultaneous eigenspaces of coarse-grained macroscopic observables. By
taking explicit account of their macroscopicality via a large deviation
principle, we prove that, for a suitably designed apparatus I, the evolution of
the composite (S+I) leads both to the reduction of the wave packet of S and to
a one-to-one correspondence between the resultant state of this microsystem and

710.3316 | Internal-state thermometry by depletion spectroscopy in a cold guided
beam of formaldehyde | We present measurements of the internal state distribution of
electrostatically guided formaldehyde. Upon excitation with continuous tunable
ultraviolet laser light the molecules dissociate, leading to a decrease in the
molecular flux. The population of individual guided states is measured by
addressing transitions originating from them. The measured populations of
selected states show good agreement with theoretical calculations for different
temperatures of the molecule source. The purity of the guided beam as deduced
from the entropy of the guided sample using a source temperature of 150K
corresponds to that of a thermal ensemble with a temperature of about 30 K.

710.3317 | Surface effects in magnetic superconductors with a spiral magnetic
structure | We consider a magnetic superconductor MS with a spiral magnetic structure. On
the basis of generalized Eilenberger and Usadel equations we show that near the
boundary of the MS with an insulator or vacuum the condensate (Gor'kov's)
Green's functions are disturbed by boundary conditions and differ essentially
from their values in the bulk. Corrections to the bulk quasiclassical Green's
functions oscillate with the period of the magnetic spiral, $2\pi /Q$, and
decay inside the superconductor over a length of the order $v/\pi T$ (ballistic
limit) or $\sqrt{D/\pi T}$ (diffusive limit). We calculate the dc Josephson
current in an MS/I/MS tunnel junction and show that the critical Josephson

710.332 | Complex Networks: Time-Dependent Connections and Silent Nodes | We studied, both analytically and numerically, complex excitable networks, in
which connections are time dependent and some of the nodes remain silent at
each time step. More specifically, (a) there is a heterogenous distribution of
connection weights and, depending on the current degree of order, some
connections are reinforced/weakened with strength Phi on short-time scales, and
(b) only a fraction rho of nodes are simultaneously active. The resulting
dynamics has attractors which, for a range of Phi values and rho exceeding a
threshold, become unstable, the instability depending critically on the value
of rho. We observe that (i) the activity describes a trajectory in which the
close neighborhood of some of the attractors is constantly visited, (ii) the
number of attractors visited increases with rho, and (iii) the trajectory may
change from regular to chaotic and vice versa as rho is, even slightly
modified. Furthermore, (iv) time series show a power-law spectra under
conditions in which the attractors' space is most efficiently explored. We

710.3321 | Efficient formalism for large scale ab initio molecular dynamics based
on time-dependent density functional theory | A new "on the fly" method to perform Born-Oppenheimer ab initio molecular
dynamics (AIMD) is presented. Inspired by Ehrenfest dynamics in time-dependent
density functional theory, the electronic orbitals are evolved by a
Schroedinger-like equation, where the orbital time derivative is multiplied by
a parameter. This parameter controls the time scale of the fictitious
electronic motion and speeds up the calculations with respect to standard
Ehrenfest dynamics. In contrast to other methods, wave function orthogonality
needs not be imposed as it is automatically preserved, which is of paramount
relevance for large scale AIMD simulations.

open-charm meson self-energies. In the $DN$ sector, the $\Lambda_c$ and
$\Sigma_c$ resonances remain close to their free-space position while acquiring
a remarkable width. As a result, the $D$ meson spectral density shows a single
pronounced peak close to the free mass that broadens with increasing density
specially towards lower energies. The low-density theorem is not a good
approximation for the repulsive $\bar D$ self-energy close to saturation
density. We discuss the implications for the $J/\Psi$ suppression at CBM
(FAIR).

710.3324 | Topology and Phases in Fermionic Systems | There can exist topological obstructions to continuously deforming a gapped
Hamiltonian for free fermions into a trivial form without closing the gap.
These topological obstructions are closely related to obstructions to the
existence of exponentially localized Wannier functions. We show that by taking
two copies of a gapped, free fermionic system with complex conjugate
Hamiltonians, it is always possible to overcome these obstructions. This allows
us to write the ground state in matrix product form using Grassman-valued bond
variables, and show insensitivity of the ground state density matrix to
boundary conditions.

710.3325 | Testing CPT Symmetry with CMB Measurements | In this paper we study the possibility of testing \emph{CPT} symmetry with
Cosmic Microwave Background (CMB) measurements. Working with an effective
lagrangian of the photon with \emph{CPT} violation ${\cal L} \sim
p_{\mu}A_{\nu}\tilde F^{\mu\nu}$ which causes the polarization vectors of the
propagating CMB photons rotated, we determine the rotation angle $\Delta\alpha$
using the BOOMERanG 2003 and the WMAP3 angular power spectra. In this analysis
we have included the newly released $TC$ and $GC$ ($l<450$) information of
WMAP3 and found $\Delta\alpha=-6.2\pm3.8$ deg at $1\sigma$ confidence level.
This result increases slightly the significance for the \emph{CPT} violation
obtained in our previous paper (Feng \emph{et al.}, 2006) $\Delta\alpha=-6.0
\pm 4.0$ deg (1$\sigma$). Furthermore we examine the constraint on the rotation
angle with the simulated Planck data. Our results show that the Planck will be

710.3326 | Narrow-Line Seyfert 1 Galaxies | I provide a short review of the properties of Narrow-line Seyfert 1 (NLS1)
galaxies across the electromagnetic spectrum and of the models to explain them.
Their continuum and emission-line properties manifest one extreme form of
Seyfert activity. As such, NLS1 galaxies may hold important clues to the key
parameters that drive nuclear activity. Their high accretion rates close to the
Eddington rate provide new insight into accretion physics, their low black hole
masses and perhaps young ages allow us to address issues of black hole growth,
their strong optical FeII emission places strong constraints on FeII and
perhaps metal formation models and physical conditions in these emission-line
clouds, and their enhanced radio quiteness permits a fresh look at causes of
radio loudness and the radio-loud radio-quiet bimodality in AGN.

710.3327 | A la Fock-Goncharov coordinates for PU(2,1) | We describe a set of coordinates on the PU(2,1)-representation variety of the
fundamental group of an oriented punctured surface $S$ with negative Euler
characteristic. The main technical tool we use is a set of geometric invariants
of a triple of flags in the complex hyperpolic plane. We establish a bijection

Parker-unstable Galactic Disks with Cosmic Rays and Shear | We analyze the electromotive force (EMF) terms and basic assumptions of the
linear and nonlinear dynamo theories in our three-dimensional (3D) numerical
model of the Parker instability with cosmic rays and shear in a galactic disk.
We also apply the well known prescriptions of the EMF obtained by the nonlinear
dynamo theory (Blackman & Field 2002 and Kleeorin et al. 2003) to check if the
EMF reconstructed from their prescriptions corresponds to the EMF obtained
directly from our numerical models. We show that our modeled EMF is fully
nonlinear and it is not possible to apply any of the considered nonlinear
dynamo approximations due to the fact that the conditions for the scale
separation are not fulfilled.

710.3329 | Universality and programmability of quantum computers | Manin, Feynman, and Deutsch have viewed quantum computing as a kind of
universal physical simulation procedure. Much of the writing about quantum
logic circuits and quantum Turing machines has shown how these machines can
simulate an arbitrary unitary transformation on a finite number of qubits. The
problem of universality has been addressed most famously in a paper by Deutsch,
and later by Bernstein and Vazirani as well as Kitaev and Solovay. The quantum
logic circuit model, developed by Feynman and Deutsch, has been more prominent
in the research literature than Deutsch's quantum Turing machines. Quantum
Turing machines form a class closely related to deterministic and probabilistic
Turing machines and one might hope to find a universal machine in this class. A
universal machine is the basis of a notion of programmability. The extent to
which universality has in fact been established by the pioneers in the field is
examined and this key notion in theoretical computer science is scrutinised in
quantum computing by distinguishing various connotations and concomitant
results and problems.
| quant-ph | manin feynman and deutsch have viewed quantum computing as a kind of universal physical simulation procedure much of the writing about quantum logic circuits and quantum turing machines has shown how these machines can simulate an arbitrary unitary transformation on a finite number of qubits the problem of universality has been addressed most famously in a paper by deutsch and later by bernstein and vazirani as well as kitaev and solovay the quantum logic circuit model developed by feynman and deutsch has been more prominent in the research literature than deutschs quantum turing machines quantum turing machines form a class closely related to deterministic and probabilistic turing machines and one might hope to find a universal machine in this class a universal machine is the basis of a notion of programmability the extent to which universality has in fact been established by the pioneers in the field is examined and this key notion in theoretical computer science is scrutinised in quantum computing by distinguishing various connotations and concomitant results and problems | [['manin', 'feynman', 'and', 'deutsch', 'have', 'viewed', 'quantum', 'computing', 'as', 'a', 'kind', 'of', 'universal', 'physical', 'simulation', 'procedure', 'much', 'of', 'the', 'writing', 'about', 'quantum', 'logic', 'circuits', 'and', 'quantum', 'turing', 'machines', 'has', 'shown', 'how', 'these', 'machines', 'can', 'simulate', 'an', 'arbitrary', 'unitary', 'transformation', 'on', 'a', 'finite', 'number', 'of', 'qubits', 'the', 'problem', 'of', 'universality', 'has', 'been', 'addressed', 'most', 'famously', 'in', 'a', 'paper', 'by', 'deutsch', 'and', 'later', 'by', 'bernstein', 'and', 'vazirani', 'as', 'well', 'as', 'kitaev', 'and', 'solovay', 'the', 'quantum', 'logic', 'circuit', 'model', 'developed', 'by', 'feynman', 'and', 'deutsch', 'has', 'been', 'more', 'prominent', 'in', 'the', 'research', 'literature', 'than', 'deutschs', 'quantum', 'turing', 'machines', 'quantum', 'turing', 'machines', 'form', 'a', 'class', 'closely', 'related', 'to', 'deterministic', 'and', 'probabilistic', 'turing', 'machines', 'and', 'one', 'might', 'hope', 'to', 'find', 'a', 'universal', 'machine', 'in', 'this', 'class', 'a', 'universal', 'machine', 'is', 'the', 'basis', 'of', 'a', 'notion', 'of', 'programmability', 'the', 'extent', 'to', 'which', 'universality', 'has', 'in', 'fact', 'been', 'established', 'by', 'the', 'pioneers', 'in', 'the', 'field', 'is', 'examined', 'and', 'this', 'key', 'notion', 'in', 'theoretical', 'computer', 'science', 'is', 'scrutinised', 'in', 'quantum', 'computing', 'by', 'distinguishing', 'various', 'connotations', 'and', 'concomitant', 'results', 'and', 'problems']] | [-0.10116116911695715, 0.16112653273969618, -0.10004593437591675, 0.08523497435098176, -0.10128801205462357, -0.2120772759669749, 0.04438757757473824, 0.3044026116105287, -0.2848417288072309, -0.29691593840238995, 0.06388973370425904, -0.20206674844113706, -0.18475624420053777, 0.25195775260435344, -0.10752181561217147, 0.18077493679903078, 0.002148804552335706, 0.0439022613501405, -0.012123159808242879, -0.2901967696093938, 0.2883286981200745, 0.04638070564469246, 0.28585496628983764, 0.04860613247541689, 0.0692129761786663, -0.011924431288930757, 0.01066845120066962, 0.03775713958556911, -0.09098190758023302, 0.1070713479696822, 0.30547991516177503, 0.19623923153692738, 0.33622273488503973, -0.4161807610081476, -0.21228185041715003, 0.09575556376295392, 0.142660848579876, 0.1483174008147094, -0.0040930624046582155, -0.28888343051566107, 0.06740890121106494, -0.18252113874054007, -0.09469548683022612, -0.10592139765554875, 0.05992599338366601, -0.04141602983796283, -0.14401121671197184, -0.029868698993372515, 0.13329590440861205, 0.11482787523854371, 0.052170302407075354, -0.0837912556622722, 0.07014622187244635, 0.05997800782911087, -0.05373244796272324, 0.06754788445385053, 0.08804616668331028, -0.1612545582493059, -0.30043655131230057, 0.3808406312835583, 0.018504362156712015, -0.1739245309924696, 0.20799206554541114, -0.061693927970284605, -0.14686585355234164, 0.026115227095804543, 0.12281680844141421, 0.05449411443949334, -0.15963539092839635, 0.14029941444961921, -0.06715571745271572, 0.116934903682215, 0.09689358561381436, 0.027878467238655214, 0.1890116697790003, 0.12989737098622653, -0.024317909210473734, 0.18659320245878172, 0.02937162263395145, -0.19099125132095396, -0.2540152269137794, -0.2030880929216639, -0.22718261851662258, 0.08631545197414725, -0.007589419941946848, -0.17774369996752487, 0.3769624310624595, 0.1375130857386945, 0.13280473961031924, 0.06694712752969227, 0.2510578416571108, 0.11381003188516683, 0.11048312072930803, 0.09997779581074913, 0.21257863390260806, 0.189654026917122, 0.1144855242543881, -0.19197356456629278, 0.10975986301261735, 0.09634742486816204] |
710.333 | Astrophysics from data analysis of spherical gravitational wave
detectors | The direct detection of gravitational waves will provide valuable
astrophysical information about many celestial objects. Also, it will be an
important test to general relativity and other theories of gravitation. The
gravitational wave detector SCHENBERG has recently undergone its first test
run. It is expected to have its first scientific run soon. In this work the
data analysis system of this spherical, resonant mass detector is tested
through the simulation of the detection of gravitational waves generated during
the inspiralling phase of a binary system. It is shown from the simulated data
that it is not necessary to have all six transducers operational in order to
determine the source's direction and the wave's amplitudes.

710.3331 | On a possible origin of a resonance-like structure in the two-photon
invariant mass spectrum of the reaction pp->ppgg | We show that the resonance-like structure found by the \emph{CELSIUS-WASA
Collaboration} in the two-photon invariant mass spectrum of the reaction $pp
\to pp \gamma \gamma$ is rather a signature of the $NN$-decoupled dibaryon
resonance $d^\star_1$(1956) that is produced in the radiative process $pp \to
\gamma d^\star_1$ and then undergoes radiative decay into two protons
$d^\star_1 \to pp \gamma$. It is found that a contribution of the dibaryon
mechanism $pp \to \gamma d^\star_1 \to pp \gamma \gamma$ of the reaction $pp
\to pp \gamma \gamma$ to the invariant mass spectrum of its photon pairs can

710.3332 | Model and Program Repair via SAT Solving | We consider the following \emph{model repair problem}: given a finite Kripke
structure $M$ and a specification formula $\eta$ in some modal or temporal
logic, determine if $M$ contains a substructure $M'$ (with the same initial
state) that satisfies $\eta$. Thus, $M$ can be ``repaired'' to satisfy the
specification $\eta$ by deleting some transitions.
We map an instance $(M, \eta)$ of model repair to a boolean formula
$\repfor(M,\eta)$ such that $(M, \eta)$ has a solution iff $\repfor(M,\eta)$ is
satisfiable. Furthermore, a satisfying assignment determines which transitions
must be removed from $M$ to generate a model $M'$ of $\eta$. Thus, we can use
any SAT solver to repair Kripke structures. Furthermore, using a complete SAT
solver yields a complete algorithm: it always finds a repair if one exists.
We extend our method to repair finite-state shared memory concurrent
programs, to solve the discrete event supervisory control problem
\cite{RW87,RW89}, to check for the existence of symmettric solutions
\cite{ES93}, and to accomodate any boolean constraint on the existence of
states and transitions in the repaired model.
Finally, we show that model repair is NP-complete for CTL, and logics with
polynomial model checking algorithms to which CTL can be reduced in polynomial
time. A notable example of such a logic is Alternating-Time Temporal Logic
(ATL).

710.3333 | Non-linear mechanical response of the Red Blood Cell | We measure the dynamical mechanical properties of human red blood cells.
Single cell response is measured with optical tweezers. We investigate both the
stress relaxation following a fast deformation, and the effect of varying the
strain rate. We find a power law decay of the stress as a function of time,
down to a plateau stress, and a power law increase of the cell's elasticity as
a function of the strain rate. Interestingly, the exponents of these quantities
violate the linear superposition principle, indicating a nonlinear response. We
propose that this is due to breaking of a fraction of the crosslinks during the
deformation process. The Soft Glassy Rheology Model accounts for the relation
between the exponents we observe experimentally. This picture is consistent
with recent models of bond remodeling in the red blood cell's molecular

| cond-mat.soft | we measure the dynamical mechanical properties of human red blood cells single cell response is measured with optical tweezers we investigate both the stress relaxation following a fast deformation and the effect of varying the strain rate we find a power law decay of the stress as a function of time down to a plateau stress and a power law increase of the cells elasticity as a function of the strain rate interestingly the exponents of these quantities violate the linear superposition principle indicating a nonlinear response we propose that this is due to breaking of a fraction of the crosslinks during the deformation process the soft glassy rheology model accounts for the relation between the exponents we observe experimentally this picture is consistent with recent models of bond remodeling in the red blood cells molecular structure our results imply that the blood cells mechanical behavior depends critically on the deformation process | [['we', 'measure', 'the', 'dynamical', 'mechanical', 'properties', 'of', 'human', 'red', 'blood', 'cells', 'single', 'cell', 'response', 'is', 'measured', 'with', 'optical', 'tweezers', 'we', 'investigate', 'both', 'the', 'stress', 'relaxation', 'following', 'a', 'fast', 'deformation', 'and', 'the', 'effect', 'of', 'varying', 'the', 'strain', 'rate', 'we', 'find', 'a', 'power', 'law', 'decay', 'of', 'the', 'stress', 'as', 'a', 'function', 'of', 'time', 'down', 'to', 'a', 'plateau', 'stress', 'and', 'a', 'power', 'law', 'increase', 'of', 'the', 'cells', 'elasticity', 'as', 'a', 'function', 'of', 'the', 'strain', 'rate', 'interestingly', 'the', 'exponents', 'of', 'these', 'quantities', 'violate', 'the', 'linear', 'superposition', 'principle', 'indicating', 'a', 'nonlinear', 'response', 'we', 'propose', 'that', 'this', 'is', 'due', 'to', 'breaking', 'of', 'a', 'fraction', 'of', 'the', 'crosslinks', 'during', 'the', 'deformation', 'process', 'the', 'soft', 'glassy', 'rheology', 'model', 'accounts', 'for', 'the', 'relation', 'between', 'the', 'exponents', 'we', 'observe', 'experimentally', 'this', 'picture', 'is', 'consistent', 'with', 'recent', 'models', 'of', 'bond', 'remodeling', 'in', 'the', 'red', 'blood', 'cells', 'molecular', 'structure', 'our', 'results', 'imply', 'that', 'the', 'blood', 'cells', 'mechanical', 'behavior', 'depends', 'critically', 'on', 'the', 'deformation', 'process']] | [-0.12761385797670013, 0.18021344100308948, -0.10947659005729579, -0.0019478808419415529, -0.026856891149164813, -0.08804278734130908, 0.07939188573417548, 0.3444117085937729, -0.29107058344801007, -0.23245093579029535, 0.054587801888517695, -0.26440275487440984, -0.23375112390127278, 0.162017164572669, -0.0688973277972668, 0.0505400274659654, 0.006616787586704288, -0.01479668728700888, -0.009453000191378555, -0.15612644514246649, 0.23279589944592627, 0.05269949338521416, 0.34866544409458966, 0.046102549846277964, 0.11186659219827944, -0.031140656388168663, 0.022259137965432416, 0.038925260666904875, -0.17561608686551872, 0.08630372767679785, 0.1629031392401071, 0.03544686353263004, 0.26659198603623446, -0.44947359449916374, -0.24375827817589438, 0.10107696305433485, 0.09294672668788974, 0.11968019031184285, -0.011806717983410252, -0.1714937927838611, 0.049025229343801345, -0.15266552901410155, -0.14497674907876276, -0.04962954487028152, 0.03419070901643289, 0.06150203710268742, -0.26629602109996514, 0.20149844610377363, 0.04808421687343262, 0.07140000344646212, -0.12367161026065189, -0.04297505848501858, -0.05083840899322623, 0.12898029821333598, 0.09118053040775091, -0.007696350065280536, 0.2575291183495306, -0.166997330067955, -0.06260771119942594, 0.3719511776909808, -0.02250337714825659, -0.16096103483639462, 0.16215735641124315, -0.1764947147733581, -0.09291739547839634, 0.14153276405628085, 0.17258207993061087, 0.07567709919548131, -0.13798273897670074, -0.004338331150632401, 0.010905167636289997, 0.2219189993461202, 0.05019270078475146, 0.014188900403065705, 0.20846040703442045, 0.21563666234770176, -0.01037225016319242, 0.1704867640548496, -0.09755831654949457, -0.05993103368612202, -0.29861599706284897, -0.16516464774797082, -0.15784845449716636, 0.08436363383723226, -0.13113767212531743, -0.18153893628071896, 0.38955151338105726, 0.059944040914017116, 0.21967027534877784, 0.11323060863651335, 0.2483320064416866, 0.11883811202776422, 0.09816397823420916, -0.011503127385175935, 0.29328081007176815, 0.15069263255358428, 0.13160136203192738, -0.3345673959012952, 0.09402522598439216, 0.03583330588758384] |

710.3335 | Non-linear numerical simulations of magneto-acoustic wave propagation in
small-scale flux tubes | We present results of non-linear, 2D, numerical simulations of
magneto-acoustic wave propagation in the photosphere and chromosphere of
small-scale flux tubes with internal structure. Waves with realistic periods of
three to five minutes are studied, after applying horizontal and vertical
oscillatory perturbations to the equilibrium model. Spurious reflections of
shock waves from the upper boundary are minimized thanks to a special boundary
condition. This has allowed us to increase the duration of the simulations and
to make it long enough to perform a statistical analysis of oscillations. The
simulations show that deep horizontal motions of the flux tube generate a slow
(magnetic) mode and a surface mode. These modes are efficiently transformed
into a slow (acoustic) mode in the vA < cS atmosphere. The slow (acoustic) mode
propagates vertically along the field lines, forms shocks and remains always
within the flux tube. It might deposit effectively the energy of the driver
into the chromosphere. When the driver oscillates with a high frequency, above
the cut-off, non-linear wave propagation occurs with the same dominant driver
period at all heights. At low frequencies, below the cut-off, the dominant
period of oscillations changes with height from that of the driver in the
photosphere to its first harmonic (half period) in the chromosphere. Depending
on the period and on the type of the driver, different shock patterns are
observed.

710.3336 | Potts Glass on Random Graphs | We solve the q-state Potts model with anti-ferromagnetic interactions on
large random lattices of finite coordination. Due to the frustration induced by
the large loops and to the local tree-like structure of the lattice this model
behaves as a mean field spin glass. We use the cavity method to compute the
temperature-coordination phase diagram and to determine the location of the
dynamic and static glass transitions, and of the Gardner instability. We show
that for q>=4 the model possesses a phenomenology similar to the one observed
in structural glasses. We also illustrate the links between the positive and
the zero-temperature cavity approaches, and discuss the consequences for the
coloring of random graphs. In particular we argue that in the colorable region
the one-step replica symmetry breaking solution is stable towards more steps of
replica symmetry breaking.

(TEK) model in four dimensions. In the numerical simulations of the zero
temperature TEK model (using a symmetric twist) we observe the existence of new
phases that break its centre symmetry at intermediate lattice couplings and for
large SU(N) gauge groups. This effect can be explained by the contribution of
diagonal configurations with collapsed eigenvalues, which are particular cases
of ``generalised fluxons''. We also investigate finite temperature versions of
the TEK model using anisotropic lattice couplings, where in particular we find
van Baal fluxons contributing at large anisotropies.

710.3339 | Investigation of the bottomonium ground state \eta_b via its inclusive
charm decays | Based on the non-relativistic QCD factorization formalism, we calculate the
bottomonium ground state, $\eta_b$, inclusive charm decays at the leading order
in the strong coupling constant $\alpha_s$ and quarkonium internal relative
velocity $v$. The inclusive charm pair production in $\eta_b$ decay is mainly
realized through $\eta_b \to c \bar{c} g$ process, where the charm and
anti-charm quarks then dominantly hadronize into charmed hadrons. The momentum
distributions of the final states are presented. In this work, we also
calculate the $J/\psi$ inclusive production rate in the $\eta_b$ decays, where
the color-octet contribution is found to be very important. We expect this
study may shed some light on finding $\eta_b$ or knowing more about its nature.

710.334 | Distances to Galactic high-velocity clouds. Complex C | We report the first determination of a distance bracket for the high-velocity
cloud (HVC) complex C. Combined with previous measurements showing that this
cloud has a metallicity of 0.15 times solar, these results provide ample
evidence that complex C traces the continuing accretion of intergalactic gas
falling onto the Milky Way. Accounting for both neutral and ionized hydrogen as
well as He, the distance bracket implies a mass of 3-14x10^6 M_sun, and the
complex represents a mass inflow of 0.1-0.25 M_sun/yr. We base our distance
bracket on the detection of CaII absorption in the spectrum of the blue
horizontal branch star SDSS J120404.78+623345.6, in combination with a
significant non-detection toward the BHB star BS 16034-0114. These results set
a strong distance bracket of 3.7-11.2 kpc on the distance to complex C. A more

710.3341 | Discrete, 3D distributed, linear imaging methods of electric neuronal
activity. Part 1: exact, zero error localization | This paper deals with the EEG/MEG neuroimaging problem: given measurements of
scalp electric potential differences (EEG: electroencephalogram) and
extracranial magnetic fields (MEG: magnetoencephalogram), find the 3D
distribution of the generating electric neuronal activity. This problem has no
unique solution. Only particular solutions with "good" localization properties
are of interest, since neuroimaging is concerned with the localization of brain
function. In this paper, a general family of linear imaging methods with exact,
zero error localization to point-test sources is presented. One particular
member of this family is sLORETA (standardized low resolution brain
electromagnetic tomography; Pascual-Marqui, Methods Find. Exp. Clin. Pharmacol.
2002, 24D:5-12;
http://www.unizh.ch/keyinst/NewLORETA/sLORETA/sLORETA-Math01.pdf). It is shown
here that sLORETA has no localization bias in the presence of measurement and
biological noise. Another member of this family, denoted as eLORETA (exact low
resolution brain electromagnetic tomography; Pascual-Marqui 2005:
http://www.research-projects.unizh.ch/p6990.htm), is a genuine inverse solution
(not merely a linear imaging method) with exact, zero error localization in the
presence of measurement and structured biological noise. The general family of
imaging methods is further extended to include data-dependent (adaptive)
quasi-linear imaging methods, also with the exact, zero error localization
property.

710.3342 | The Conjugate Linearized Ricci Flow on Closed 3-Manifolds | We characterize the conjugate linearized Ricci flow and the associated
backward heat kernel on closed three--manifolds of bounded geometry. We discuss
their properties, and introduce the notion of Ricci flow conjugated constraint
sets which characterizes a way of Ricci flow averaging metric dependent
geometrical data. We also provide an integral representation of the Ricci flow
metric itself and of its Ricci tensor in terms of the heat kernel of the
conjugate linearized Ricci flow. These results, which readily extend to closed

710.3345 | The final spin from the coalescence of aligned-spin black-hole binaries | Determining the final spin of a black-hole (BH) binary is a question of key
importance in astrophysics. Modelling this quantity in general is made
difficult by the fact that it depends on the 7-dimensional space of parameters
characterizing the two initial black holes. However, in special cases, when
symmetries can be exploited, the description can become simpler. For black-hole
binaries with unequal masses but with equal spins which are aligned with the
orbital angular momentum, we show that the use of recent simulations and basic
but exact constraints derived from the extreme mass-ratio limit allow to model
this quantity with a simple analytic expression. Despite the simple dependence,
the expression models very accurately all of the available estimates, with
errors of a couple of percent at most. We also discuss how to use the fit to
predict when a Schwarzschild BH is produced by the merger of two spinning BHs,
when the total angular momentum of the spacetime ``flips'' sign, or under what
conditions the final BH is ``spun-up'' by the merger. Finally, suggest an
extension of the fit to include unequal-spin binaries, thus potentially
providing a complete description of the final spin from the coalescence of
generic black-hole binaries with spins aligned to the orbital angular momentum.
| gr-qc astro-ph | determining the final spin of a blackhole bh binary is a question of key importance in astrophysics modelling this quantity in general is made difficult by the fact that it depends on the 7dimensional space of parameters characterizing the two initial black holes however in special cases when symmetries can be exploited the description can become simpler for blackhole binaries with unequal masses but with equal spins which are aligned with the orbital angular momentum we show that the use of recent simulations and basic but exact constraints derived from the extreme massratio limit allow to model this quantity with a simple analytic expression despite the simple dependence the expression models very accurately all of the available estimates with errors of a couple of percent at most we also discuss how to use the fit to predict when a schwarzschild bh is produced by the merger of two spinning bhs when the total angular momentum of the spacetime flips sign or under what conditions the final bh is spunup by the merger finally suggest an extension of the fit to include unequalspin binaries thus potentially providing a complete description of the

710.3347 | The compact group--fossil group connection: observations of a massive
compact group at z=0.22 | It has been suggested that fossil groups could be the cannibalized remains of
compact groups, that lost energy through tidal friction. However, in the nearby
universe, compact groups which are close to the merging phase and display a
wealth of interacting features (such as HCG 31 and HCG 79) have very low
velocity dispersions and poor neighborhoods, unlike the massive, cluster-like
fossil groups studied to date. In fact, known z=0 compact groups are very
seldom embedded in massive enough structures which may have resembled the
intergalactic medium of fossil groups. In this paper we study the dynamical
properties of CG6, a massive compact group at z=0.220 that has several
properties in common with known fossil groups. We report on new g' and i'
imaging and multi-slit spectroscopic performed with GMOS on Gemini South. The
system has 20 members, within a radius of 1 h_70^-1 Mpc, a velocity dispersion
of 700 km/s and has a mass of 1.8 x 10^14 h_70^-1 Msun, similar to that of the
most massive fossil groups known. The merging of the four central galaxies in
this group would form a galaxy with magnitude M_r' ~ -23.4, typical for
first-ranked galaxies of fossil groups. Although nearby compact groups with
similar properties to CG 6 are rare, we speculate that such systems occurred
more frequently in the past and they may have been the precursors of fossil
groups.

710.335 | Fully Correlated Electronic Dynamics for Antiproton Impact Ionization of
Helium | We present total cross sections for single and double ionization of helium by
antiproton impact over a wide range of impact energies from 10 keV/amu to 1
MeV/amu. A non-perturbative time-dependent close-coupling method (TDCC) is
applied to fully treat the correlated dynamics of the ionized electrons.
Excellent agreement is obtained between our calculations and experimental
measurements of total single and double ionization cross sections at high
impact energies, whereas for lower impact energies, some discrepancies with
experiment are found. At an impact energy of 1 MeV we also find that the
double-to-single ionization ratio is twice as large for antiproton impact as

710.3351 | The Rich Mid-Infrared Environments of Two Highly-Obscured X-ray
Binaries: Spitzer Observations of IGR J16318-4848 and GX 301-2 | We present the results of Spitzer mid-infrared spectroscopic observations of
two highly-obscured massive X-ray binaries: IGR J16318-4848 and GX301-2. Our
observations reveal for the first time the extremely rich mid-infrared
environments of this type of source, including multiple continuum emission
components (a hot component with T > 700 K and a warm component with T ~ 180 K)
with apparent silicate absorption features, numerous HI recombination lines,
many forbidden ionic lines of low ionization potentials, and pure rotational H2
lines. This indicates that both sources have hot and warm circumstellar dust,
ionized stellar winds, extended low-density ionized regions, and
photo-dissociated regions. It appears difficult to attribute the total optical
extinction of both sources to the hot and warm dust components, which suggests
that there could be an otherwise observable colder dust component responsible
for the most of the optical extinction and silicate absorption features. The
observed mid-infrared spectra are similar to those from Luminous Blue
Variables, indicating that the highly-obscured massive X-ray binaries may
represent a previously unknown evolutionary phase of X-ray binaries with
early-type optical companions. Our results highlight the importance and utility
of mid-infrared spectroscopy to investigate highly-obscured X-ray binaries.

710.3352 | Applications of Level Curves to Some Problems on Algebraic Surfaces | In a previous work of the authors, a result to algorithmically compute the
topology types of the level curves of an algebraic surface, is given. From this
result, here we derive applications based on level curves to determine some
topological features of surfaces (reality, compactness, connectivity) and to
the problem of plotting.
| math.AG | in a previous work of the authors a result to algorithmically compute the topology types of the level curves of an algebraic surface is given from this result here we derive applications based on level curves to determine some topological features of surfaces reality compactness connectivity and to the problem of plotting | [['in', 'a', 'previous', 'work', 'of', 'the', 'authors', 'a', 'result', 'to', 'algorithmically', 'compute', 'the', 'topology', 'types', 'of', 'the', 'level', 'curves', 'of', 'an', 'algebraic', 'surface', 'is', 'given', 'from', 'this', 'result', 'here', 'we', 'derive', 'applications', 'based', 'on', 'level', 'curves', 'to', 'determine', 'some', 'topological', 'features', 'of', 'surfaces', 'reality', 'compactness', 'connectivity', 'and', 'to', 'the', 'problem', 'of', 'plotting']] | [-0.13540793693839356, 0.03547701333865497, -0.1562607895511274, 0.07748829104149571, -0.09311306841958028, -0.05959740859599641, 0.10451021702745213, 0.3317008964144267, -0.29080096523438653, -0.32672564667434645, 0.08739198898099577, -0.2512433359112877, -0.20548536743109042, 0.2441303967184817, -0.15509077318263456, 0.028350895610996164, 0.022031119209714234, 0.03642772607362041, -0.08951216770443492, -0.27821916087458914, 0.400574115713915, 0.002054997433263522, 0.24286882741412577, 0.1020094413699833, 0.04383733848897883, 8.186666617313257e-05, -0.024696841567324903, 0.0258086182248707, -0.1878252972338277, 0.2158363927312446, 0.2546632746950938, 0.11967223020754038, 0.1844453254284767, -0.4215368449759598, -0.22843767506464457, 0.08681876726376896, 0.06132444642627469, 0.11568507006338152, -0.0148336317394681, -0.2664816352682045, 0.13575582508929074, -0.10557994361107166, -0.18029248001627052, -0.0488443670507807, 0.04048494670468454, 0.037535634581357814, -0.18041691527916834, -0.013614092792312685, 0.06974494124117953, 0.13210535907329848, -0.0930455697592921, -0.0469615261155503, -0.02888381717583308, 0.1438388206745283, 0.044499409183537446, 0.020869535507070117, 0.07935876590020668, -0.1441959564242727, -0.12216709183457379, 0.3545557828261875, -0.02588465797285048, -0.19094776082783937, 0.19911652035527647, -0.10236942687501702, -0.15301912628078404, 0.10026123303060348, 0.18586222080585474, 0.14016844242667922, -0.1323117608598505, 0.09617150211236619, -0.03691026672291068, 0.14380844815884933, 0.058538521048971094, 0.024407975733853303, 0.1359871024839007, 0.13035998029562718, 0.08011141918205585, 0.14528769066628927, -0.06208106120958781, -0.015021914553541977, -0.3037104714446916, -0.190755432122387, -0.19683855700378233, 0.04657239918238842, -0.05017072600821848, -0.21751587755548266, 0.46686198447759336, 0.1365753784059332, 0.24667290863222802, 0.06796487576614779, 0.28109400114044547, 0.13855793402315333, -0.0041735918404391175, 0.056589764766753294, 0.18264186204368554, 0.14276965496201927, 0.033019840762090795, -0.14377962170132938, 0.04320718139374199, 0.13034342392347753] |
