710.0854 | 2D Cooling of Magnetized Neutron Stars | Context: Many thermally emitting isolated neutron stars have magnetic fields
larger than 10^13 G. A realistic cooling model that includes the presence of
high magnetic fields should be reconsidered. Aims: We investigate the effects
of anisotropic temperature distribution and Joule heating on the cooling of
magnetized neutron stars. Methods: The 2D heat transfer equation with
anisotropic thermal conductivity tensor and including all relevant neutrino
emission processes is solved for realistic models of the neutron star interior
and crust. Results: The presence of the magnetic field affects significantly
the thermal surface distribution and the cooling history during both, the early
neutrino cooling era and the late photon cooling era. Conclusions: There is a
large effect of the Joule heating on the thermal evolution of strongly
magnetized neutron stars. Both magnetic fields and Joule heating play a key
role in keeping magnetars warm for a long time. Moreover, this effect is
important for intermediate field neutron stars and should be considered in
radio-quiet isolated neutron stars or high magnetic field radio-pulsars.

710.0855 | Secular effects on inflation from one-loop quantum gravity | In this paper we revisit and extend a previous analysis where the possible
relevance of quantum gravity effects in a cosmological setup was studied. The
object of interest are non-local (logarithmic) terms generated in the effective
action of gravity due to the exchange in loops of massless modes (such as
photons or the gravitons themselves). We correct one mistake existing in the
previous work and discuss the issue in a more general setting in different
cosmological scenarios. We obtain the one-loop quantum-corrected evolution
equations for the cosmological scale factor up to a given order in a derivative
expansion in two particular cases: a matter dominated universe with vanishing
cosmological constant, and in a de Sitter universe. We show that the quantum
corrections, albeit tiny, may have a secular effect that eventually modifies
the expansion rate. For a de Sitter universe they tend to slow down the rate of
the expansion, while the effect seems to have the opposite sign in a matter

| gr-qc | in this paper we revisit and extend a previous analysis where the possible relevance of quantum gravity effects in a cosmological setup was studied the object of interest are nonlocal logarithmic terms generated in the effective action of gravity due to the exchange in loops of massless modes such as photons or the gravitons themselves we correct one mistake existing in the previous work and discuss the issue in a more general setting in different cosmological scenarios we obtain the oneloop quantumcorrected evolution equations for the cosmological scale factor up to a given order in a derivative expansion in two particular cases a matter dominated universe with vanishing cosmological constant and in a de sitter universe we show that the quantum corrections albeit tiny may have a secular effect that eventually modifies the expansion rate for a de sitter universe they tend to slow down the rate of the expansion while the effect seems to have the opposite sign in a matter dominated universe to partly understand these effects we provide a complementary newtonian analysis | [['in', 'this', 'paper', 'we', 'revisit', 'and', 'extend', 'a', 'previous', 'analysis', 'where', 'the', 'possible', 'relevance', 'of', 'quantum', 'gravity', 'effects', 'in', 'a', 'cosmological', 'setup', 'was', 'studied', 'the', 'object', 'of', 'interest', 'are', 'nonlocal', 'logarithmic', 'terms', 'generated', 'in', 'the', 'effective', 'action', 'of', 'gravity', 'due', 'to', 'the', 'exchange', 'in', 'loops', 'of', 'massless', 'modes', 'such', 'as', 'photons', 'or', 'the', 'gravitons', 'themselves', 'we', 'correct', 'one', 'mistake', 'existing', 'in', 'the', 'previous', 'work', 'and', 'discuss', 'the', 'issue', 'in', 'a', 'more', 'general', 'setting', 'in', 'different', 'cosmological', 'scenarios', 'we', 'obtain', 'the', 'oneloop', 'quantumcorrected', 'evolution', 'equations', 'for', 'the', 'cosmological', 'scale', 'factor', 'up', 'to', 'a', 'given', 'order', 'in', 'a', 'derivative', 'expansion', 'in', 'two', 'particular', 'cases', 'a', 'matter', 'dominated', 'universe', 'with', 'vanishing', 'cosmological', 'constant', 'and', 'in', 'a', 'de', 'sitter', 'universe', 'we', 'show', 'that', 'the', 'quantum', 'corrections', 'albeit', 'tiny', 'may', 'have', 'a', 'secular', 'effect', 'that', 'eventually', 'modifies', 'the', 'expansion', 'rate', 'for', 'a', 'de', 'sitter', 'universe', 'they', 'tend', 'to', 'slow', 'down', 'the', 'rate', 'of', 'the', 'expansion', 'while', 'the', 'effect', 'seems', 'to', 'have', 'the', 'opposite', 'sign', 'in', 'a', 'matter', 'dominated', 'universe', 'to', 'partly', 'understand', 'these', 'effects', 'we', 'provide', 'a', 'complementary', 'newtonian', 'analysis']] | [-0.15380177157997552, 0.1427866432855704, -0.12872963908194962, 0.1238710625389857, -0.08700910897925496, -0.08370589672853904, -0.005400255132034155, 0.29406740028943334, -0.209044290616044, -0.2881222780428028, 0.0740069895297555, -0.26399863076529334, -0.11273573437306497, 0.15479223836080305, -0.0381141147150525, 0.002962641165192638, -0.005658998220626797, 0.036673981464368156, -0.05452664561669475, -0.2797981895799083, 0.3366850333767278, 0.08623812672149922, 0.22057796941804034, 0.03004841422662139, 0.0817768896717046, -0.060994515802179065, -0.0645549525453576, 0.044982241189313106, -0.15528411524145797, 0.05142393545646753, 0.21636480128126484, 0.04627042406371661, 0.2681632047838398, -0.43012544942753655, -0.23723690513388387, 0.12571197068318724, 0.18281911371807966, 0.20874445188923607, -0.06548524280985085, -0.25287955669420104, 0.050692109933921266, -0.20517791289037893, -0.14078633516494718, -0.048663538002542084, 0.005277413757784026, -0.09285721804979923, -0.22595760003264462, 0.1283022894223021, 0.04229723549314908, -0.04571467342786491, -0.05064953110579933, -0.057452510321911954, 0.03449679339570658, 0.09566130272112787, 0.11761331726264741, 0.03270675020292401, 0.12734035136178135, -0.1759523964047964, -0.10662119249680213, 0.41662466430238315, -0.14899534454702268, -0.1800948016505156, 0.16914870774905597, -0.19871787601815802, -0.14863073970058135, 0.07722762174691265, 0.1514727620145173, 0.13788082662437642, -0.12499219361692666, 0.1497994557119507, 0.04760108898792948, 0.12474924124245133, 0.11598819127306342, 0.04820470745442435, 0.26691249085324154, 0.09927727007839296, 0.016627835891475633, 0.10492127221543342, -0.011026788904730763, -0.1176794278172643, -0.3411544437174286, -0.14850829430789286, -0.11584483836644462, 0.0738894123956561, -0.1249123165088739, -0.17539666141915533, 0.3501525131985545, 0.15939409425548676, 0.1966960617447538, 0.027056369935827596, 0.27806220268564563, 0.0869820883810254, 0.04891893438329654, 0.06344992699633752, 0.3110542566894687, 0.10579142670546259, 0.1279677850074534, -0.24680639759238276, 0.02016752907141511, 0.05458999289598848] |

710.0857 | Dynamic Programming Optimization over Random Data: the Scaling Exponent
for Near-optimal Solutions | A very simple example of an algorithmic problem solvable by dynamic
programming is to maximize, over sets A in {1,2,...,n}, the objective function
|A| - \sum_i \xi_i 1(i \in A,i+1 \in A) for given \xi_i > 0. This problem, with
random (\xi_i), provides a test example for studying the relationship between
optimal and near-optimal solutions of combinatorial optimization problems. We
show that, amongst solutions differing from the optimal solution in a small
proportion \delta of places, we can find near-optimal solutions whose objective
function value differs from the optimum by a factor of order \delta^2 but not
smaller order. We conjecture this relationship holds widely in the context of
dynamic programming over random data, and Monte Carlo simulations for the
Kauffman-Levin NK model are consistent with the conjecture. This work is a
technical contribution to a broad program initiated in Aldous-Percus (2003) of
relating such scaling exponents to the algorithmic difficulty of optimization
problems.

modulation of the hopping matrix elements can correspond to a non-real Higgs
field with non-trivial vorticity. This provides a natural setting for
fractionally charged vortices with localized zero modes. For fullerene-like
molecules we employ the index theorem to demonstrate the existence of six
low-lying states that do not depend strongly on the Kekule-induced mass gap.

contribution of voice system messages to visual search efficiency and comfort.
Messages which include spatial information on the target location are meant to
support search for familiar targets in collections of photographs (30 per
display). 24 participants carried out 240 visual search tasks in two conditions
differing from each other in initial target presentation only. The isolated
target was presented either simultaneously with an oral message (multimodal
presentation, MP), or without any message (visual presentation, VP). Averaged
target selection times were thrice longer and errors almost twice more frequent
in the VP condition than in the MP condition. In addition, the contribution of
spatial messages to visual search rapidity and accuracy was influenced by
display layout and task difficulty. Most results are statistically significant.
Besides, subjective judgments indicate that oral messages were well accepted.

710.0861 | Tailoring of phononic band structures in colloidal crystals | We report an experimental study of the elastic properties of a
two-dimensional (2D) colloidal crystal subjected to light-induced substrate
potentials. In agreement with recent theoretical predictions [H.H. von
Gruenberg and J. Baumgartl, Phys. Rev. E 75, 051406 (2007)] the phonon band
structure of such systems can be tuned depending on the symmetry and depth of
the substrate potential. Calculations with binary crystals suggest that
phononic band engineering can be also performed by variations of the pair

710.0863 | Highly Excited Mesons, Linear Regge Trajectories and the Pattern of the
Chiral Symmetry Realization | The chiral symmetry of QCD shows up in the linear Weyl--Wigner mode at short
Euclidean distances or at high temperatures. On the other hand, low-lying
hadronic states exhibit the nonlinear Nambu--Goldstone mode. An interesting
question was raised as to whether the linear realization of the chiral symmetry
is asymptotically restored for highly excited states. We address it in a number
of ways. On the phenomenological side we argue that to the extent the meson
Regge trajectories are observed to be linear and equidistant, the Weyl--Wigner
mode is not realized.
This picture is supported by quasiclassical arguments implying that the quark
spin interactions in high excitations are weak, the trajectories are linear,
and there is no chiral symmetry restoration. Then we use the string/gauge
duality. In the top-down Sakai--Sugimoto construction the nonlinear realization
of the chiral symmetry is built in. In the bottom-up AdS/QCD construction by
Erlich et al., and Karch et al. the situation is more ambiguous. However, in
this approach linearity and equidistance of the Regge trajectories can be
naturally implemented, with the chiral symmetry in the Nambu--Goldstone mode.
Asymptotic chiral symmetry restoration might be possible if a nonlinearity
(convergence) of the Regge trajectories in an "intermediate window" of $n,J$,
beyond the explored domain, takes place. This would signal the failure of the
quasiclassical picture.

710.0864 | Evidence of random magnetic anisotropy in ferrihydrite nanoparticles
based on analysis of statistical distributions | We show that the magnetic anisotropy energy of antiferromagnetic ferrihydrite
depends on the square root of the nanoparticles volume, using a method based on
the analysis of statistical distributions. The size distribution was obtained
by transmission electron microscopy, and the anisotropy energy distributions
were obtained from ac magnetic susceptibility and magnetic relaxation. The
square root dependence corresponds to random local anisotropy, whose average is
given by its variance, and can be understood in terms of the recently proposed
single phase homogeneous structure of ferrihydrite.

710.0865 | Secrecy Capacity of the Wiretap Channel with Noisy Feedback | In this work, the role of noisy feedback in enhancing the secrecy capacity of
the wiretap channel is investigated. A model is considered in which the
feed-forward and feedback signals share the same noisy channel. More
specifically, a discrete memoryless modulo-additive channel with a full-duplex
destination node is considered first, and it is shown that a judicious use of
feedback increases the perfect secrecy capacity to the capacity of the
source-destination channel in the absence of the wiretapper. In the
achievability scheme, the feedback signal corresponds to a private key, known
only to the destination. Then a half-duplex system is considered, for which a
novel feedback technique that always achieves a positive perfect secrecy rate
(even when the source-wiretapper channel is less noisy than the
source-destination channel) is proposed. These results hinge on the
modulo-additive property of the channel, which is exploited by the destination
to perform encryption over the channel without revealing its key to the source.

710.0866 | Abundance Patterns in Stars in the Bulge and Galactic Center | We discuss oxygen and iron abundance patterns in K and M red-giant members of
the Galactic bulge and in the young and massive M-type stars inhabiting the
very center of the Milky Way. The abundance results from the different bulge
studies in the literature, both in the optical and the infrared, indicate that
the [O/Fe]-[Fe/H] relation in the bulge does not follow the disk relation, with
[O/Fe] values falling above those of the disk. Based on these elevated values
of [O/Fe] extending to large Fe abundances, it is suggested that the bulge
underwent a rapid chemical enrichment with perhaps a top-heavy initial mass
function. The Galactic Center stars reveal a nearly uniform and slightly
elevated (relative to solar) iron abundance for a studied sample which is
composed of 10 red giants and supergiants. Perhaps of more significance is the
fact that the young Galactic Center M-type stars show abundance patterns that
are reminiscent of those observed for the bulge population and contain enhanced
abundance ratios of alpha-elements relative to either the Sun or Milky Way disk
at near-solar metallicities.
| astro-ph | we discuss oxygen and iron abundance patterns in k and m redgiant members of the galactic bulge and in the young and massive mtype stars inhabiting the very center of the milky way the abundance results from the different bulge studies in the literature both in the optical and the infrared indicate that the ofefeh relation in the bulge does not follow the disk relation with ofe values falling above those of the disk based on these elevated values of ofe extending to large fe abundances it is suggested that the bulge underwent a rapid chemical enrichment with perhaps a topheavy initial mass function the galactic center stars reveal a nearly uniform and slightly elevated relative to solar iron abundance for a studied sample which is composed of 10 red giants and supergiants perhaps of more significance is the fact that the young galactic center mtype stars show abundance patterns that are reminiscent of those observed for the bulge population and contain enhanced abundance ratios of alphaelements relative to either the sun or milky way disk at nearsolar metallicities | [['we', 'discuss', 'oxygen', 'and', 'iron', 'abundance', 'patterns', 'in', 'k', 'and', 'm', 'redgiant', 'members', 'of', 'the', 'galactic', 'bulge', 'and', 'in', 'the', 'young', 'and', 'massive', 'mtype', 'stars', 'inhabiting', 'the', 'very', 'center', 'of', 'the', 'milky', 'way', 'the', 'abundance', 'results', 'from', 'the', 'different', 'bulge', 'studies', 'in', 'the', 'literature', 'both', 'in', 'the', 'optical', 'and', 'the', 'infrared', 'indicate', 'that', 'the', 'ofefeh', 'relation', 'in', 'the', 'bulge', 'does', 'not', 'follow', 'the', 'disk', 'relation', 'with', 'ofe', 'values', 'falling', 'above', 'those', 'of', 'the', 'disk', 'based', 'on', 'these', 'elevated', 'values', 'of', 'ofe', 'extending', 'to', 'large', 'fe', 'abundances', 'it', 'is', 'suggested', 'that', 'the', 'bulge', 'underwent', 'a', 'rapid', 'chemical', 'enrichment', 'with', 'perhaps', 'a', 'topheavy', 'initial', 'mass', 'function', 'the', 'galactic', 'center', 'stars', 'reveal', 'a', 'nearly', 'uniform', 'and', 'slightly', 'elevated', 'relative', 'to', 'solar', 'iron', 'abundance', 'for', 'a', 'studied', 'sample', 'which', 'is', 'composed', 'of', '10', 'red', 'giants', 'and', 'supergiants', 'perhaps', 'of', 'more', 'significance', 'is', 'the', 'fact', 'that', 'the', 'young', 'galactic', 'center', 'mtype', 'stars', 'show', 'abundance', 'patterns', 'that', 'are', 'reminiscent', 'of', 'those', 'observed', 'for', 'the', 'bulge', 'population', 'and', 'contain', 'enhanced', 'abundance', 'ratios', 'of', 'alphaelements', 'relative', 'to', 'either', 'the', 'sun', 'or', 'milky', 'way', 'disk', 'at', 'nearsolar', 'metallicities']] | [-0.025892636264601525, 0.14531171007352417, -0.06293310049386999, 0.09807172838882049, -0.08611670372989445, -0.02260787652378808, 0.09098528037315973, 0.41963361303566554, -0.14776101195404318, -0.37515754595154366, -0.026089133380641692, -0.2962836746865228, -0.00012556313245697728, 0.18420952222278789, -0.08482420409628966, -0.07811486597128041, 0.07082906142709641, -0.06790808611549437, -0.04700153305418998, -0.2776893799918929, 0.3028102654485063, 0.028637102732237157, 0.14427349274176793, -0.10289086741213192, -0.030631721625234618, -0.18030663675436095, -0.04783370050825387, -0.01620966947166634, -0.13335374360413071, 0.06765884126135924, 0.25357714490106525, 0.14048484909769626, 0.17422704765893124, -0.33155382531232497, -0.18285794852154497, 0.07065987410335983, 0.2255726220273522, 0.04023248042752602, -0.16983939169533097, -0.20940387389992035, 0.0891488927524464, -0.15079698084681895, -0.23575540280812446, 0.11704485609804868, 0.05887499233374799, 0.025660041534971426, -0.213889237433443, 0.14424132870434778, 0.05696968173170163, 0.15229782344794224, -0.12895959800020818, -0.20997460599072984, -0.1295624399536898, 0.06635785621445231, 0.05465974331073796, 0.04305502639396647, 0.21800751471079044, -0.1011754221506625, 0.029072017377689895, 0.41294113754206363, -0.11826764459217061, 0.036563945330637795, 0.2659315864656995, -0.25046481852882735, -0.18245083940158177, 0.08871488777046513, 0.10482337178828913, 0.1394436410264055, -0.15302637965007368, 0.027171049771736788, -0.036875254445964234, 0.20561565906745927, 0.08673095627942815, 0.030718850914919594, 0.3410320019771543, 0.08878054837670239, 0.0593098232271566, 0.035275166702076956, -0.19076168111411013, -0.10233335859303534, -0.1645161841173953, -0.14197026080368658, -0.05162998890587488, 0.06583483754691354, -0.19288498266696327, -0.16226489370813665, 0.28935282053077965, 0.0770877754021769, 0.27676130147057704, 0.014191098482440377, 0.29259232284927833, 0.06755765748610876, 0.1598652605846649, 0.1315290335385004, 0.32541302477098044, 0.2284577021898192, 0.09925725337510731, -0.2864032745551235, 0.14960087850617046, -0.003889700353624268] |
710.0867 | The case for an aggressive program of dark energy probes | The observed cosmic acceleration presents the physics and cosmology
communities with amazing opportunities to make exciting, probably even radical
advances in these fields. This topic is highly data driven and many of our
opportunities depend on us undertaking an ambitious observational program. Here
I outline the case for such a program based on both the exciting science
related to the cosmic acceleration and the impressive impact that a strong
observational program would have. Along the way, I challenge a number of
arguments that skeptics use to question the value of a strong observational
commitment to this field.

710.0869 | Lattice Results for Vector Meson Couplings and Parton Distribution
Amplitudes | We present results for the couplings of light vector mesons to vector and
tensor currents and on the low moments of the light-cone distribution
amplitudes of the pion and kaon. The calculations are performed on the RBC and
UKQCD collaborations' ensembles generated with the Iwasaki gauge action and
with 2+1 flavours of domain wall fermions. The (preliminary) results for the
ratios of the couplings of the vector meson to the vector and tensor currents
(f_V and f^T_V respectively) in the MSbar scheme at 2GeV are:
f_\rho^T/f_\rho=0.681(20); f_{K^\ast}^T/f_{K^\ast}=0.712(11) and
f_\phi^T/f_\phi=0.751(9). For the first moment of the kaon's distribution

710.087 | Subadditivity of the entropy and its relation to Brascamp-Lieb type
inequalities | We prove a general duality result showing that a Brascamp--Lieb type
inequality is equivalent to an inequality expressing subadditivity of the
entropy, with a complete correspondence of best constants and cases of
equality. This open a new approach to the proof of Brascamp--Lieb type
inequalities, via subadditivity of the entropy. We illustrate the utility of
this approach by proving a general inequality expressing the subadditivity
property of the entropy on $\R^n$, and fully determining the cases of equality.
As a consequence of the duality mentioned above, we obtain a simple new proof
of the classical Brascamp--Lieb inequality, and also a fully explicit
determination of all of the cases of equality. We also deduce several other
consequences of the general subadditivity inequality, including a
generalization of Hadamard's inequality for determinants. Finally, we also
prove a second duality theorem relating superadditivity of the Fisher
information and a sharp convolution type inequality for the fundamental
eigenvalues of Schr\"odinger operators. Though we focus mainly on the case of
random variables in $\R^n$ in this paper, we discuss extensions to other
settings as well.

710.0871 | Spreadsheets in Clinical Medicine | There is overwhelming evidence that the continued and widespread use of
untested spreadsheets in business gives rise to regular, significant and
unexpected financial losses. Whilst this is worrying, it is perhaps a
relatively minor concern compared with the risks arising from the use of poorly
constructed and/or untested spreadsheets in medicine, a practice that is
already occurring. This article is intended as a warning that the use of poorly
constructed and/or untested spreadsheets in clinical medicine cannot be
tolerated. It supports this warning by reporting on potentially serious

710.0872 | Stability of a Nonlinear Axially Moving String With the Kelvin-Voigt
Damping | In this paper, a nonlinear axially moving string with the Kelvin-Voigt
damping is considered. It is proved that the string is stable, i.e., its
transversal displacement converges to zero when the axial speed of the string
is less than a certain critical value. The proof is established by showing that
a Lyapunov function corresponding to the string decays to zero exponentially.
It is also shown that the string displacement is bounded when a bounded
distributed force is applied to it transversally. Furthermore, a few open
problems regarding the stability and stabilization of strings with the
Kelvin-Voigt damping are stated.

710.0873 | Mirror Mediation | I show that the effective action of string compactifications has a structure
that can naturally solve the supersymmetric flavour and CP problems. At leading
order in the g_s and \alpha' expansions, the hidden sector factorises. The
moduli space splits into two mirror parts that depend on Kahler and complex
structure moduli. Holomorphy implies the flavour structure of the Yukawa
couplings arises in only one part. In type IIA string theory flavour arises
through the Kahler moduli sector and in type IIB flavour arises through the
complex structure moduli sector. This factorisation gives a simple solution to
the supersymmetric flavour and CP problems: flavour physics is generated in one
sector while supersymmetry is broken in the mirror sector. This mechanism does
not require the presence of gauge, gaugino or anomaly mediation and is

710.0874 | A luminosity constraint on the origin of unidentified high energy
sources | The identification of point sources poses a great challenge for the high
energy community. We present a new approach to evaluate the likelihood of a set
of sources being a Galactic population based on the simple assumption that
galaxies similar to the Milky Way host comparable populations of gamma-ray
emitters. We propose a luminosity constraint on Galactic source populations
which complements existing approaches by constraining the abundance and spatial
distribution of any objects of Galactic origin, rather than focusing on the
properties of a specific candidate emitter. We use M31 as a proxy for the Milky
Way, and demonstrate this technique by applying it to the unidentified EGRET
sources. We find that it is highly improbable that the majority of the
unidentified EGRET sources are members of a Galactic halo population (e.g.,
dark matter subhalos), but that current observations do not provide any
constraints on all of these sources being Galactic objects if they reside
entirely in the disk and bulge. Applying this method to upcoming observations
by the Fermi Gamma-ray Space Telescope has the potential to exclude association
of an even larger number of unidentified sources with any Galactic source
class.

710.0875 | Evidence of Cosmic Evolution of the Stellar Initial Mass Function | Theoretical arguments and indirect observational evidence suggest that the
stellar initial mass function (IMF) may evolve with time, such that it is more
weighted toward high mass stars at higher redshift. Here we test this idea by
comparing the rate of luminosity evolution of massive early-type galaxies in
clusters at 0.02<z<0.83 to the rate of their color evolution. A combined fit to
the rest-frame U-V color evolution and the previously measured evolution of the
M/L_B ratio gives x~-0.3 for the logarithmic slope of the IMF in the region
around 1 Solar mass, flatter than the present-day value in the Milky Way disk
of x=1.3. The best-fitting luminosity-weighted formation redshift of the stars
in massive cluster galaxies is ~3.7, and a possible interpretation is that the
characteristic mass m_c had a value of ~2 Solar masses at z~4 (compared to
m_c~0.1 Solar masses today), in qualitative agreement with models in which the
characteristic mass is a function of the Jeans mass in molecular clouds. Such a
``bottom-light'' IMF for massive cluster galaxies has significant implications
for the interpretation of measurements of galaxy formation and evolution.
Applying a simple form of IMF evolution to literature data, we find that the
volume-averaged star formation rate at high redshift may have been
overestimated (by a factor of 3-4 at z>4), and the cosmic star formation
history may have a fairly well-defined peak at z~1.5. The M/L_V ratios of
galaxies are less affected than their star formation rates, and future data on
the stellar mass density at z>3 will provide further constraints on IMF
evolution. The formal errors likely underestimate the uncertainties, and
confirmation of thes results requires a larger sample of clusters and the
inclusion of redder rest-frame colors in the analysis.

710.0876 | Spin Meissner Effect in Superconductors and the Origin of the Meissner
Effect | We propose a dynamical explanation of the Meissner effect in superconductors
and predict the existence of a spin Meissner effect: that a macroscopic spin
current flows within a London penetration depth $\lambda_L$ of the surface of
superconductors in the absence of applied external fields, with carrier density
= the superfluid density and carrier speed $v=\hbar/(4m_e\lambda_L$)
($m_e=$bare electron mass). The two members of a Cooper pair circulate in
orbits of radius $2\lambda_L$ in opposite direction and the spin current in a
Cooper pair has orbital angular momentum $\hbar$. Our description also provides
a 'geometric' interpretation of the difference between type I and type II
superconductors.

as well as applications-oriented point of view. Here we study the emerging
morphology of in-vacuo prepared graphene films using low energy electron
microscopy (LEEM) and angle-resolved photoemission (ARPES). We obtain an
identification of single and bilayer of graphene film by comparing the
characteristic features in electron reflectivity spectra in LEEM to the PI-band

accurately determine the local extent of graphene layers as well as the layer
thickness.

710.0878 | The Total Merger Rate of Compact Object Binaries In The Local Universe | Using a population synthesis approach, we compute the total merger rate in
the local Universe for double neutron stars, double black holes, and black hole
-- neutron star binaries. These compact binaries are the prime source
candidates for gravitational-wave detection by LIGO and VIRGO. We account for
mergers originating from field populations and from dense stellar clusters. For
both populations we use the same treatment of stellar evolution. Our results
indicate that the merger rates of double neutron stars and black hole --
neutron star binaries are strongly dominated by field populations, while
merging black hole binaries are formed much more effectively in dense stellar
clusters. The overall merger rate of double compact objects depends sensitively
on the (largely unknown) initial mass fraction contained in dense clusters
f_cl. For f_cl < 0.0001, the Advanced LIGO detection rate will be dominated by
field populations of double neutron star mergers, with a small but significant
number of detections ~20 yr^-1. However for a higher mass fraction in clusters,
f_cl > 0.001, the detection rate will be dominated by numerous mergers of
double black holes originating from dense clusters, and it will be considerably
higher, ~25 - 300 yr^-1. In addition, we show that, once mergers of double
black holes are detected, it is easy to differentiate between systems formed in
the field and in dense clusters, since the chirp mass distributions are
strikingly different. Finally, we point out that there may exist a population
of merging black hole binaries in intergalactic space.

significant number of detections 20 yr1 however for a higher mass fraction in clusters f_cl 0001 the detection rate will be dominated by numerous mergers of double black holes originating from dense clusters and it will be considerably higher 25 300 yr1 in addition we show that once mergers of double black holes are detected it is easy to differentiate between systems formed in the field and in dense clusters since the chirp mass distributions are strikingly different finally we point out that there may exist a population of merging black hole binaries in intergalactic space | [['using',

710.0879 | Close encounters of three black holes | We present the first fully relativistic longterm numerical evolutions of
three equal-mass black holes in a system consisting of a third black hole in a
close orbit about a black-hole binary. We find that these
close-three-black-hole systems have very different merger dynamics from
black-hole binaries. In particular, we see complex trajectories, a
redistribution of energy that can impart substantial kicks to one of the holes,
distinctive waveforms, and suppression of the emitted gravitational radiation.
We evolve two such configurations and find very different behaviors. In one
configuration the binary is quickly disrupted and the individual holes follow
complicated trajectories and merge with the third hole in rapid succession,
while in the other, the binary completes a half-orbit before the initial merger
of one of the members with the third black hole, and the resulting
two-black-hole system forms a highly elliptical, well separated binary that
shows no significant inspiral for (at least) the first t~1000M of evolution.

710.088 | Continuum and Symmetry-Conserving Effects in Drip-line Nuclei Using
Finite-range Forces | We report the first calculations of nuclear properties near the drip-lines
using the spherical Hartree-Fock-Bogoliubov mean-field theory with a
finite-range force supplemented by continuum and particle number projection
effects. Calculations were carried out in a basis made of the eigenstates of a
Woods-Saxon potential computed in a box, thereby garanteeing that continuum
effects were properly taken into account. Projection of the self-consistent
solutions on good particle number was carried out after variation, and an
approximation of the variation after projection result was used. We give the
position of the drip-lines and examine neutron densities in neutron-rich

710.0881 | Biomarkers set in context | In a famous paper, Sagan et al.(1993) analyzed a spectrum of the Earth taken
by the Galileo probe, searching for signatures of life. They concluded that the
large amount of O2 and the simultaneous presence of CH4 traces are strongly
suggestive of biology. The detection of a widespread red-absorbing pigment with
no likely mineral origin supports the hypothesis of biophotosynthesis. The
search for signs of life on possibly very different planets implies that we
need to gather as much information as possible in order to understand how the
observed atmosphere physically and chemically works.
The Earth-Sun intensity ratio is about 10^{-7} in the thermal infrared (10
micrometer), and about 10^{-10} in the visible (0.5 micrometer). The
interferometric systems suggested for Darwin and the Terrestrial Planet Finder
Interferometer (TPF-I) mission operates in the mid-IR (5 - 20 micrometer), the
coronagraph suggested for Terrestrial Planet Finder Coronagraph (TPF-C) in the
visible (0.5 - 1 micrometer). For the former it is thus the thermal emission
emanating from the planet that is detected and analyzed while for the later the
reflected stellar flux is measured. The spectrum of the planet can contain
signatures of atmospheric species that are important for habitability, like CO2
and H2O, or result from biological activity (O2, O3, CH4, and N2O). Both
spectral regions contain atmospheric bio-indicators. The presence or absence of
these spectral features will indicate similarities or differences with the
atmospheres of terrestrial planets and are discussed in detail and set into
context with the physical characteristics of a planet in this chapter.

710.0882 | On the most compact regular lattice in large dimensions: A statistical
mechanical approach | In this paper I will approach the computation of the maximum density of
regular lattices in large dimensions using a statistical mechanics approach.
The starting point will be some theorems of Roger, which are virtually unknown
in the community of physicists. Using his approach one can see that there are
many similarities (and differences) with the problem of computing the entropy
of a liquid of perfect spheres. The relation between the two problems is

710.0883 | Fluctuation-driven directed transport in the presence of Levy flights | Numerical evidence of directed transport driven by symmetric Levy noise in
time-independent ratchet potentials in the absence of an external tilting force
is presented. The results are based on the numerical solution of the fractional
Fokker-Planck equation in a periodic potential and the corresponding Langevin
equation with Levy noise. The Levy noise drives the system out of thermodynamic
equilibrium and an up-hill net current is generated. For small values of the
noise intensity there is an optimal value of the Levy noise index yielding the
maximum current. The direction and magnitude of the current can be manipulated
by changing the Levy noise asymmetry and the potential asymmetry.

710.0885 | The Quantum Formalism and the GRW Formalism | The Ghirardi-Rimini-Weber (GRW) theory of spontaneous wave function collapse
is known to provide a quantum theory without observers, in fact two different
ones by using either the matter density ontology (GRWm) or the flash ontology
(GRWf). Both theories are known to make predictions different from those of
quantum mechanics, but the difference is so small that no decisive experiment
can as yet be performed. While some testable deviations from quantum mechanics
have long been known, we provide here something that has until now been
missing: a formalism that succinctly summarizes the empirical predictions of
GRWm and GRWf. We call it the GRW formalism. Its structure is similar to that
of the quantum formalism but involves different operators. In other words, we
establish the validity of a general algorithm for directly computing the

Quasimodules tie together module theory and twisted module theory, and both
twisted and untwisted modules feature Poincare-Birkhoff-Witt-like spanning

710.0891 | Gap excitations in a four-leg Heisenberg spin tube antiferromagnet | Inelastic neutron scattering is used to investigate magnetic excitations in
the quasi-one-dimensional quantum spin-liquid system Cu2Cl4 D8C4SO2. Contrary
to previously conjectured models that relied on bond-alternating nearest
neighbor interactions in the spin chains, the dominant interactions are
actually next-nearest-neighbor in-chain antiferromagnetic couplings. The
appropriate Heisenberg Hamiltonian is equivalent to that of a S = 1/2 4-leg
spin-tube with almost perfect one dimensionality and no bond alternation. A

710.0892 | Prediction and verification of indirect interactions in densely
interconnected regulatory networks | We develop a matrix-based approach to predict and verify indirect
interactions in gene and protein regulatory networks. It is based on the
approximate transitivity of indirect regulations (e.g. A regulates B and B
regulates C often implies that A regulates C) and optimally takes into account
the length of a cascade and signs of intermediate interactions. Our method is
at its most powerful when applied to large and densely interconnected networks.
It successfully predicts both the yet unknown indirect regulations, as well as
the sign (activation or repression) of already known ones. The reliability of
sign predictions was calibrated using the gold-standard sets of positive and
negative interactions. We fine-tuned the parameters of our algorithm by
maximizing the area under the Receiver Operating Characteristic (ROC) curve. We
then applied the optimized algorithm to large literature-derived networks of
all direct and indirect regulatory interactions in several model organisms
(Homo sapiens, Saccharomyces cerevisiae, Arabidopsis thaliana and Drosophila
melanogaster).

710.0893 | A Galaxy in Transition: Structure, Globular Clusters, and Distance of
the Star-Forming S0 Galaxy NGC 1533 in Dorado | We use two-band imaging data from the Advanced Camera for Surveys on board
the Hubble Space Telescope for a detailed study of NGC1533, an SB0 galaxy in
the Dorado group surrounded by a ring of HI. NGC1533 appears to be completing a
transition from late to early type: it is red, but not quite dead. Faint spiral
structure becomes visible following galaxy subtraction, and luminous blue stars
can be seen in isolated areas of the disk. Dust is visible in the color map in
the region around the bar, and there is a linear color gradient throughout the
disk. We determine an accurate distance from the surface brightness
fluctuations (SBF) method, finding m-M = 31.44\pm0.12 mag, or d = 19.4\pm1.1
Mpc. We then study the globular cluster (GC) colors, sizes, and luminosity
function (GCLF). Estimates of the distance from the median of the GC half-light
radii and from the peak of the GCLF both agree well with the SBF distance. The
GC specific frequency is S_N=1.3\pm0.2, typical for an early-type disk galaxy.
The color distribution is bimodal, as commonly observed for bright galaxies.
There is a suggestion of the redder GCs having smaller sizes, but the trend is
not significant. The sizes do increase significantly with galactocentric
radius, in a manner more similar to the Milky Way GC system than to those in
Virgo. This difference may be an effect of the steeper density gradients in
loose groups as compared to galaxy clusters. Additional studies of early-type
galaxies in low density regions can help determine if this is indeed a general
environmental trend.

710.0896 | Gapped itinerant spin excitations account for missing entropy in the
hidden order state of URu$_2$Si$_2$ | One of the primary goals of modern condensed matter physics is to elucidate
the nature of the ground state in various electronic systems. Many correlated
electron materials, such as high temperature superconductors, geometrically
frustrated oxides, and low-dimensional magnets are still the objects of
fruitful study because of the unique properties which arise due to poorly
understood many-body effects. Heavy fermion metals - materials which have high
effective electron masses due to these effects - represent a class of materials
with exotic properties, such as unusual magnetism, unconventional
superconductivity, and "hidden order" parameters. The heavy fermion
superconductor URu2Si2 has held the attention of physicists for the last two
decades due to the presence of a "hidden order" phase below 17.5 K. Neutron
scattering measurements indicate that the ordered moment is 0.03 $\mu_{B}$,
much too small to account for the large heat capacity anomaly at 17.5 K. We
present recent neutron scattering experiments which unveil a new piece of this
puzzle - the spin excitation spectrum above 17.5 K exhibits well-correlated,
itinerant-like spin excitations up to at least 10 meV emanating from
incommensurate wavevectors. The gapping of these excitations corresponds to a
large entropy release and explains the reduction in the electronic specific
heat through the transition.

710.0898 | HD 17156b: A Transiting Planet with a 21.2 Day Period and an Eccentric
Orbit | We report the detection of transits by the 3.1 M_Jup companion to the V=8.17
G0V star HD 17156. The transit was observed by three independant observers on
Sept. 9/10, 2007 (two in central Italy and one in the Canary Islands), who
obtained detections at confidence levels of 3.0 sigma, 5.3 sigma, and 7.9
sigma, respectively. The observations were carried out under the auspices of
the Transitsearch.org network, which organizes follow-up photometric transit
searches of known planet-bearing stars during the time intervals when transits
are expected to possibly occur. Analyses of the 7.9 sigma data set indicates a
transit depth d=0.0062+/-0.0004, and a transit duration t=186+/-5 min. These
values are consistent with the transit of a Jupiter-sized planet with an impact
parameter b=a*cos(i)/R_star ~ 0.8. This planet occupies a unique regime among
known transiting extrasolar planets, both as a result of its large orbital
eccentricity (e=0.67) and long orbital period (P=21.2 d). The planet receives a
26-fold variation in insolation during the course of its orbit, which will make
it a useful object for characterization of exoplanetary atmospheric dynamics.

710.0899 | Instability of P-waves just below the transition region in a global
solar wind simulation | We investigate how wave propagation is modified by the presence of heat
sources and sinks, in the simple 1D, hydrodynamical case, including
chromosphere and solar wind. We integrate the time-dependent hydrodynamic
equations of the solar wind with spherical symmetry, including conduction,
radiative cooling and a prescribed mechanical heat flux. Once a
quasi-stationary wind is established, we study the response of the system to
pressure oscillations at the photospheric boundary. We use transparent boundary
conditions. We find that wavepackets with high enough amplitude propagating
upward from the photosphere implode just below the transition region. This
implosion is due to the radiative cooling term generating pressure holes close
to the wave crests of the wave, which make the wave collapse. In the case where
heat sources and sinks are not present in the equations, the wave remains
stable whatever the initial wave amplitude, which is compatible with published

710.09 | A New Achievability Scheme for the Relay Channel | In this paper, we propose a new coding scheme for the general relay channel.
This coding scheme is in the form of a block Markov code. The transmitter uses
a superposition Markov code. The relay compresses the received signal and maps
the compressed version of the received signal into a codeword conditioned on
the codeword of the previous block. The receiver performs joint decoding after
it has received all of the B blocks. We show that this coding scheme can be
viewed as a generalization of the well-known Compress-And-Forward (CAF) scheme
proposed by Cover and El Gamal. Our coding scheme provides options for
preserving the correlation between the channel inputs of the transmitter and
the relay, which is not possible in the CAF scheme. Thus, our proposed scheme
may potentially yield a larger achievable rate than the CAF scheme.

710.0901 | Diffuse Interstellar Bands in z < 0.6 CaII Absorbers | The diffuse interstellar bands (DIBs) probably arise from complex organic
molecules whose strength in local galaxies correlates with neutral hydrogen
column density, N(HI), and dust reddening, E(B-V). Since CaII absorbers in
quasar (QSO) spectra are posited to have high N(HI) and significant E(B-V),
they represent promising sites for the detection of DIBs at cosmological
distances. Here we present the results from the first search for DIBs in 9
CaII-selected absorbers at 0.07 < z_abs < 0.55. We detect the 5780Ang DIB in
one line of sight at z_abs = 0.1556; this is only the second QSO absorber in
which a DIB has been detected. Unlike the majority of local DIB sight-lines,
both QSO absorbers with detected DIBs show weak 6284Ang absorption compared
with the 5780Ang band. This may be indicative of different physical conditions
in intermediate redshift QSO absorbers compared with local galaxies. Assuming
that local relations between the 5780Ang DIB strength and N(HI) and E(B-V)
apply in QSO absorbers, DIB detections and limits can be used to derive N(HI)
and E(B-V). For the one absorber in this study with a detected DIB, we derive
E(B-V) = 0.23mag and log[N(HI)] >= 20.9, consistent with previous conclusions
that CaII systems have high HI column densities and significant reddening. For
the remaining 8 CaII-selected absorbers with 5780Ang DIB non-detections, we
derive E(B-V) upper limits of 0.1-0.3mag.

710.0902 | Distinguishing quantum operations having few Kraus operators | Entanglement is sometimes helpful in distinguishing between quantum
operations, as differences between quantum operations can become magnified when
their inputs are entangled with auxiliary systems. Bounds on the dimension of
the auxiliary system needed to optimally distinguish quantum operations are
known in several situations. For instance, the dimension of the auxiliary space
never needs to exceed the dimension of the input space of the operations for
optimal distinguishability, while no auxiliary system whatsoever is needed to
optimally distinguish unitary operations. Another bound, which follows from
work of R. Timoney, is that optimal distinguishability is always possible when
the dimension of the auxiliary system is twice the number of operators needed
to express the difference between the quantum operations in Kraus form. This
paper provides an alternate proof of this fact that is based on concepts and
tools that are familiar to quantum information theorists.

710.0904 | A Quantitative Link Between Globular Clusters and the Stellar Halos in
Elliptical Galaxies | This paper explores the quantitative connection between globular clusters and
the diffuse stellar population of the galaxies they are associated with. Both
NGC 1399 and NGC 4486 (M87) are well suited for this kind of analysis due to
their large globular cluster populations. The main assumption of our Monte
Carlo based models is that each globular cluster is formed along with a given
diffuse stellar mass that shares the same spatial distribution, chemical
composition and age. The main globular clusters subpopulations, that determine
the observed bimodal colour distribution, are decomposed avoiding a priori
parametric (e.g. Gaussian) fits and using a new colour (C-T1)-metallicity
relation. The eventual detectability of a blue tilt in the colour magnitude
diagrams of the blue globulars subpopulation is also addressed. A successful
link between globular clusters and the stellar galaxy halo is established by
assuming that the number of globular clusters per associated diffuse stellar
mass t is a function of total abundance [Z/H] and behaves as
t=gamma*exp(delta[Z/H]) (i.e. increases when abundance decreases).

710.0905 | Rank 2 vector bundles on ind-Grassmannians | The simplest example of an ind-Grassmannian is the infinite projective space
$\mathbf P^\infty$. The Barth-Van de Ven-Tyurin (BVT) Theorem, proved more than
30 years ago \cite{BV}, \cite{T}, \cite{Sa} (see also a recent proof by A.
Coand\u{a} and G. Trautmann, \cite{CT}), claims that any vector bundle of
finite rank on $\mathbf P^\infty$ is isomorphic to a direct sum of line
bundles. In the last decade natural examples of infinite flag varieties (or
flag ind-varieties) have arisen as homogeneous spaces of locally linear
ind-groups, \cite{DPW}, \cite{DiP}. In the present paper we concentrate our
attention to the special case of ind-Grassmannians, i.e. to inductive limits of
Grassmannians of growing dimension.

710.0906 | Bounded generalized Harish-Chandra modules | Let $\gg$ be a complex reductive Lie algebra and $\kk\subset\gg$ be any
reductive in $\gg$ subalgebra. We call a $(\gg,\kk)$-module $M$ bounded if the
$\kk$-multiplicities of $M$ are uniformly bounded. In this paper we initiate a
general study of simple bounded $(\gg,\kk)$-modules. We prove a strong
necessary condition for a subalgebra $\kk$ to be bounded (Corollary
\ref{cor1.6}), i.e. to admit an infinite-dimensional simple bounded
$(\gg,\kk)$-module, and then establish a sufficient condition for a subalgebra
$\kk$ to be bounded (Theorem \ref{thGroups2}). As a result we are able to
classify all maximal bounded reductive subalgebras of $\gg=\sl(n)$.
In the second half of the paper we describe in detail simple bounded
infinite-dimensional $(\gg,\sl(2))$-modules, and in particular compute their
characters and minimal $\sl(2)$-types. We show that if $\sl(2)$ is a bounded
subalgebra of $\gg$ which is not contained in a proper ideal of $\gg$, then
$\gg\simeq \sl(2)\oplus \sl(2), \sl(3),\sp(4)$; alltogether, up to conjugation
there are five possible embeddings of $\sl(2)$ as a bounded subalgebra into
$\gg$ as above. In two of these cases $\sl(2)$ is a symmetric subalgebra, and
many results about simple bounded $(\gg,\sl(2))$-modules are known. A case
where our results are entirely new is the case of a principal
$\sl(2)$-subalgebra in $\sp(4)$.

710.0907 | Spitzer IRAC Observations of White Dwarfs. I. Warm Dust at Metal-Rich
Degenerates | This paper presents the results of a Spitzer IRAC 3-8 micron photometric
search for warm dust orbiting 17 nearby, metal-rich white dwarfs, 15 of which
apparently have hydrogen dominated atmospheres (type DAZ). G166-58, G29-38, and
GD 362 manifest excess emission in their IRAC fluxes and the latter two are
known to harbor dust grains warm enough to radiate detectable emission at
near-infrared wavelengths as short as 2 micron. Their IRAC fluxes display
differences compatible with a relatively larger amount of cooler dust at GD
362. G166-58 is presently unique in that it appears to exhibit excess flux only
at wavelengths longer than about 5 micron. Evidence is presented that this
mid-infrared emission is most likely associated with the white dwarf,
indicating that G166-58 bears circumstellar dust no warmer than T~400 K. The
remaining 14 targets reveal no reliable mid-infrared excess, indicating the
majority of DAZ stars do not have warm debris disks sufficiently opaque to be
detected by IRAC.

710.0908 | The Starting and Stopping Problem under Knightian Uncertainty and
Related Systems of Reflected BSDEs | This article deals with the starting and stopping problem under Knightian
uncertainty, i.e., roughly speaking, when the probability under which the
future evolves is not exactly known. We show that the lower price of a plant
submitted to the decisions of starting and stopping is given by a solution of a
system of two reflected backward stochastic differential equations (BSDEs for
short). We solve this latter system and we give the expression of the optimal
strategy. Further we consider a more general system of $m$ ($m\geq 2$)
reflected BSDEs with interconnected obstacles. Once more we show existence and
uniqueness of the solution of that system.

710.091 | Charm spectroscopy on dynamical 2+1 flavor domain wall fermion lattices
with a relativistic heavy quark action | We present a preliminary calculation of the charmonium spectrum using the
dynamical 2+1 flavor $24^3\times 64$ domain wall fermion lattice configurations
generated by the RBC and UKQCD collaborations. We use the relativistic heavy
quark action with 3 parameters non-perturbatively determined by matching to
experimental quantities. Chiral extrapolation is done on four light sea quark
masses from 0.005 to 0.03, with $m_s=0.04$ and $m_{res}=0.003$. We can either
predict meson masses assuming the lattice spacing is known from other methods,
or calculate the lattice spacing using those quantities.

710.0912 | Fano-Kondo effect in a two-level system with triple quantum dots: shot
noise characteristics | We theoretically compare transport properties of Fano-Kondo effect with those
of Fano effect. We focus on shot noise characteristics of a triple quantum dot
(QD) system in the Fano-Kondo region at zero temperature, and discuss the

710.0913 | Information flow within stochastic dynamical systems | Information flow or information transfer is an important concept in dynamical
systems which has applications in a wide variety of scientific disciplines. In
this study, we show that a rigorous formalism can be established in the context
of a generic stochastic dynamical system. The resulting measure of of
information transfer possesses a property of transfer asymmetry and, when the
stochastic perturbation to the receiving component does not rely on the giving
component, has a form same as that for the corresponding deterministic system.
An application with a two-dimensional system is presented, and the resulting
transfers are just as expected. A remarkable observation is that, for two
highly correlated time series, there could be no information transfer from one
certain series, say $x_2$, to the other ($x_1$). That is to say, the evolution
of $x_1$ may have nothing to do with $x_2$, even though $x_1$ and $x_2$ are
highly correlated. Information transfer analysis thus extends the traditional
notion of correlation analysis by providing a quantitative measure of causality
between time series.

In spatial dimension d>1, anti-coarsening arises in which the linear dimension
L of minority domains grows as t^{1/(d+1)}. One consequence is that the time to

710.0915 | Hawking Radiation as Quantum Tunneling in Rindler Coordinate | We substantiate the Hawking radiation as quantum tunneling of fields or
particles crossing the horizon by using the Rindler coordinate. The thermal
spectrum detected by an accelerated particle is interpreted as quantum
tunneling in the Rindler spacetime. Representing the spacetime near the horizon
locally as a Rindler spacetime, we find the emission rate by tunneling, which

710.0916 | Acoustic phonon transport through a double-bend quantum waveguide | In this work, using the scattering matrix method, we have investigated the
transmission coefficients and the thermal conductivity in a double-bend
waveguide structure. The transmission coefficients show strong resonances due
to the scattering in the midsection of a double-bend structure; the positions
and the widths of the resonance peaks are determined by the dimensions of the
midsection of the structure. And the scattering in the double-bend structure
makes the thermal conductivity decreases with the increasing of the temperature
first, then increases after reaches a minimum. Furthermore, the investigations
of the multiple double-bend structures indicate that the first additional
double-bend structure suppresses the transmission coefficient and the frequency
gap formed; and the additional double-bend structures determine the numbers of
the resonance peaks at the frequency just above the gap region. These results
could be useful for the design of phonon devices.

\alpha=j/c\rho_GJ, where \rho_GJ is the corotation charge density. The
customary assumption \alpha\approx 1 is not supported by recent simulations of
pulsar magnetospheres and we study polar caps with arbitrary \alpha. We argue
that no significant activity is generated on field lines with 0<\alpha<1.
Charges are extracted from the star and flow along such field lines with low
energies. By contrast, if \alpha>1 or \alpha<0, a high voltage is generated,
leading to unsteady e^+- discharge on a scale-height smaller than the size of
the polar cap. The discharge can power observed pulsars. Voltage fluctuations
in the discharge imply unsteady twisting of the open flux tube and generation
of Alfven waves. These waves are ducted along the tube and converted to
electromagnetic waves, providing a new mechanism for pulsar radiation.

710.0921 | Realization of the mean-field universality class in spin-crossover
materials | In spin-crossover materials, the volume of a molecule changes depending on
whether it is in the high-spin (HS) or low-spin (LS) state. This change causes
distortion of the lattice. Elastic interactions among these distortions play an
important role for the cooperative properties of spin-transition phenomena. We
find that the critical behavior caused by this elastic interaction belongs to
the mean-field universality class, in which the critical exponents for the
spontaneous magnetization and the susceptibility are $\beta = 1/2$ and $\gamma
= 1$, respectively. Furthermore, the spin-spin correlation function is a
constant at long distances, and it does not show an exponential decay in
contrast to short-range models. The value of the correlation function at long
distances shows different size-dependences: $O(1/N)$, $O(1/\sqrt{N})$, and
constant for temperatures above, at, and below the critical temperature,
respectively. The model does not exhibit clusters, even near the critical
point. We also found that cluster growth is suppressed in the present model and
that there is no critical opalescence in the coexistence region. During the

characteristics of the mean-field model are expected to be found not only in
spin-crossover materials, but also generally in systems where elastic
distortion mediates the interaction among local states.
| cond-mat.mtrl-sci cond-mat.stat-mech | in spincrossover materials the volume of a molecule changes depending on whether it is in the highspin hs or lowspin ls state this change causes distortion of the lattice elastic interactions among these distortions play an important role for the cooperative properties of spintransition phenomena we find that the critical behavior caused by this elastic interaction belongs to the meanfield universality class in which the critical exponents for the spontaneous magnetization and the susceptibility are beta 12 and gamma 1 respectively furthermore the spinspin correlation function is a constant at long distances and it does not show an exponential decay in contrast to shortrange models the value of the correlation function at long distances shows different sizedependences o1n o1sqrtn and constant for temperatures above at and below the critical temperature respectively the model does not exhibit clusters even near the critical point we also found that cluster growth is suppressed in the present model and that there is no critical opalescence in the coexistence region during the relaxation process from a metastable state at the end of a

710.0923 | Bayesian analysis of time series of single RNA under fluctuating force | Extracting the intrinsic kinetic information of biological molecule from its
single-molecule kinetic data is of considerable biophysical interest. In this
work, we theoretically investigate the feasibility of inferring single RNA's
intrinsic kinetic parameters from the time series obtained by forced
folding/unfolding experiment done in the light tweezer, where the molecule is
flanked by long double-stranded DNA/RNA handles and tethered between two big
beads. We first construct a coarse-grain physical model of the experimental
system. The model has captured the major physical factors: the Brownian motion
of the bead, the molecular structural transition, and the elasticity of the
handles and RNA. Then based on an analytic solution of the model, a Bayesian
method using Monte Carlo Markov Chain is proposed to infer the intrinsic
kinetic parameters of the RNA from the noisy time series of the distance or
force. Because the force fluctuation induced by the Brownian motion of the bead
and the structural transition can significantly modulate the transition rates
of the RNA, we prove that, this statistic method is more accurate and efficient
than the conventional histogram fitting method in inferring the molecule's
intrinsic parameters.

710.0924 | On The 5D Extra-Force according to Basini-Capozziello-Ponce De Leon
Formalism and the Experimental Research of Extra Dimensions On-Board
International Space Station(ISS) using Laser Beams | We analyze the possibility of Experimental Research of Extra Dimensions
On-Board International Space Station (ISS) by using a Satellite carrying a
Laser device(optical Laser) on the other side of Earth Orbit targeted towards
ISS.The Sun will be between the Satellite and the ISS so the Laser will pass
the neighborhoods of the Sun at a distance $R$ in order to reach ISS. The Laser
beam will be Gravitationally Bent according to Classical General Relativity and
the Extra Terms predicted by Kar-Sinha in the Gravitational Bending Of Light
due to the presence of Extra Dimensions can perhaps be measured with precision
equipment.By computing the Gravitational Bending according to Einstein we know
the exact position where the Laser will reach the target on-board ISS.However
if the Laser arrives at ISS with a Bending different than the one predicted by
Einstein and if this difference is equal to the Extra Terms predicted by
Kar-Sinha then this experience would proof that we live in a Universe of more
than 4 Dimensions.We demonstrate in this work that ISS have the needed
precision to detect these Extra Terms(see eq 137 in this work).Such experience
would resemble the measures of the Gravitational Bending Of Light by Sir Arthur
Stanley Eddington in the Sun Eclipse of 1919 that helped to proof the
correctness of General Relativity although in ISS case would have more degres
of accuracy because we would be free from the interference of Earth Atmosphere.

710.0926 | Characterizing Generic Global Rigidity | A d-dimensional framework is a graph and a map from its vertices to E^d. Such
a framework is globally rigid if it is the only framework in E^d with the same
graph and edge lengths, up to rigid motions. For which underlying graphs is a
generic framework globally rigid? We answer this question by proving a
conjecture by Connelly, that his sufficient condition is also necessary: a
generic framework is globally rigid if and only if it has a stress matrix with
kernel of dimension d+1, the minimum possible.
An alternate version of the condition comes from considering the geometry of
the length-squared mapping l: the graph is generically locally rigid iff the
rank of l is maximal, and it is generically globally rigid iff the rank of the
Gauss map on the image of l is maximal.
We also show that this condition is efficiently checkable with a randomized

710.0927 | Optical pumping via incoherent Raman transitions | A new optical pumping scheme is presented that uses incoherent Raman
transitions to prepare a trapped Cesium atom in a specific Zeeman state within
the 6S_{1/2}, F=3 hyperfine manifold. An important advantage of this scheme
over existing optical pumping schemes is that the atom can be prepared in any
of the F=3 Zeeman states. We demonstrate the scheme in the context of cavity
quantum electrodynamics, but the technique is equally applicable to a wide
variety of atomic systems with hyperfine ground-state structure.

710.0931 | A Kinetic Model for Photoswitching of magnetism in the High Spin
Molecule [Mo(IV)(CN)2(CN-Cu(II)(tren))6](ClO4)8 | The heptanuclear complex [Mo(IV)(CN)2(CN-CuL)6]8+ exhibits photomagnetism. An
earlier microscopic model showed that the transition dipole moments for
excitation in different spin manifolds are similar in magnitude. In this paper,
we attribute photomagnetism to the long lived S=3 charge transfer excited state
for which there appears to be sufficient experimental evidence. We model the
photomagnetism by employing a kinetic model which includes internal conversions
and intersystem crossings. The key feature of the model is assumption of the
existence of two kinds of S=3 states: one which has no direct pathway for
internal conversion and the other characterized by slow kinetics for internal
conversion to the low-energy states. The trapped S=3 state can decay via a
thermally activated barrier to the other S=3 state. The experimental
temperature dependence of magnetization plot is fitted using rate constants
with Arrhenius dependence. The two different experimental cMT vs. T curves
obtained with different irradiation times are fitted with our model. Our
studies show that the photomagnetism in these systems is governed by kinetics
and not due to differences in oscillator strengths for excitation of the
different spin states.

710.0932 | Mapping giant magnetic fields around dense solid plasmas by high
resolution magneto-optical microscopy | We investigate distribution of magnetic fields around dense solid plasmas
generated by intense p-polarized laser (~10^{16} W.cm^{-2}, 100 fs) irradiation
of magnetic tapes, using high sensitivity magneto optical microscopy. We
present evidence for giant axial magnetic fields and map out for the first time
the spatial distribution of these fields. By using the axial magnetic field
distribution as a diagnostic tool we uncover evidence for angular momentum
associated with the plasma. We believe this study holds significance for
investigating the process under which a magnetic material magnetizes or
demagnetizes under the influence of ultrashort intense laser pulses.

710.0934 | Effect of Impurity Scattering on the Nonlinear Microwave Response in
High-Tc Superconductors | We theoretically investigate intermodulation distortion in high-Tc
superconductors. We study the effect of nonmagnetic impurities on the real and
imaginary parts of nonlinear conductivity. The nonlinear conductivity is
proportional to the inverse of temperature owing to the dependence of the
damping effect on energy, which arises from the phase shift deviating from the
unitary limit. It is shown that the final-states interaction makes the real
part predominant over the imaginary part. These effects have not been included

710.0935 | Self-consistent quasiparticle RPA for multi-level pairing model | Particle-number projection within the Lipkin-Nogami (LN) method is applied to
the self-consistent quasiparticle random-phase approximation (SCQRPA), which is
tested in an exactly solvable multi-level pairing model. The SCQRPA equations
are numerically solved to find the energies of the ground and excited states at
various numbers $\Omega$ of doubly degenerate equidistant levels. The use of
the LN method allows one to avoid the collapse of the BCS (QRPA) to obtain the
energies of the ground and excited states as smooth functions of the
interaction parameter $G$. The comparison between results given by different
approximations such as the SCRPA, QRPA, LNQRPA, SCQRPA and LNSCQRPA is carried
out. While the use of the LN method significantly improves the agreement with
the exact results in the intermediate coupling region, we found that in the
strong coupling region the SCQRPA results are closest to the exact ones.

710.0936 | Single artificial-atom lasing | Solid-state superconducting circuits are versatile systems in which quantum
states can be engineered and controlled. Recent progress in this area has
opened up exciting possibilities for exploring fundamental physics as well as
applications in quantum information technology; in a series of experiments it
was shown that such circuits can be exploited to generate quantum optical
phenomena, by designing superconducting elements as artificial atoms that are
coupled coherently to the photon field of a resonator. Here we demonstrate a
lasing effect with a single artificial atom - a Josephson-junction charge qubit
- embedded in a superconducting resonator. We make use of one of the properties
of solid-state artificial atoms, namely that they are strongly and controllably
coupled to the resonator modes. The device is essentially different from

710.0938 | Partitioning 3-homogeneous latin bitrades | A latin bitrade $(T^{\diamond}, T^{\otimes})$ is a pair of partial latin
squares which defines the difference between two arbitrary latin squares
$L^{\diamond} \supseteq T^{\diamond}$ and $L^{\diamond} \supseteq T^{\otimes}$
of the same order. A 3-homogeneous bitrade $(T^{\diamond}, T^{\otimes})$ has
three entries in each row, three entries in each column, and each symbol
appears three times in $T^{\diamond}$. Cavenagh (2006) showed that any
3-homogeneous bitrade may be partitioned into three transversals. In this paper
we provide an independent proof of Cavenagh's result using geometric methods.
In doing so we provide a framework for studying bitrades as tessellations of
spherical, euclidean or hyperbolic space.

710.0939 | Stabilizability and percolation in the infinite volume sandpile model | We study the sandpile model in infinite volume on $\mathbb{Z}^d$. In
particular, we are interested in the question whether or not initial
configurations, chosen according to a stationary measure $\mu$, are
$\mu$-almost surely stabilizable. We prove that stabilizability does not depend
on the particular procedure of stabilization we adopt. In $d=1$ and $\mu$ a
product measure with density $\rho=1$ (the known critical value for
stabilizability in $d=1$) with a positive density of empty sites, we prove that
$\mu$ is not stabilizable. Furthermore, we study, for values of $\rho$ such
that $\mu$ is stabilizable, percolation of toppled sites. We find that for
$\rho>0$ small enough, there is a subcritical regime where the distribution of
a cluster of toppled sites has an exponential tail, as is the case in the
subcritical regime for ordinary percolation.

hadrons | In this talk we review the theoretical status of the lifetime ratios of heavy
hadrons and of the B-mixing quantities $\Delta M_s$, $\Delta \Gamma_s$ and
$\phi_s$. While $\Delta M_s$ and $\Delta \Gamma_s$ suffer from large
uncertainties due to the badly known decay constants, the ratio $\Delta
\Gamma_s / \Delta M_s$ can be determined with almost no non-perturbative
uncertainties, therefore it can be used to look for possible new physics
effects.

710.0941 | Projective Ring Line of an Arbitrary Single Qudit | As a continuation of our previous work (arXiv:0708.4333) an algebraic
geometrical study of a single $d$-dimensional qudit is made, with $d$ being
{\it any} positive integer. The study is based on an intricate relation between
the symplectic module of the generalized Pauli group of the qudit and the fine
structure of the projective line over the (modular) ring $\bZ_{d}$. Explicit
formulae are given for both the number of generalized Pauli operators commuting
with a given one and the number of points of the projective line containing the
corresponding vector of $\bZ^{2}_{d}$. We find, remarkably, that a perp-set is
not a set-theoretic union of the corresponding points of the associated
projective line unless $d$ is a product of distinct primes. The operators are
also seen to be structured into disjoint `layers' according to the degree of

710.0942 | Sharp asymptotics for the partition function of some continuous-time
directed polymers | This paper is concerned with two related types of directed polymers in a
random medium. The first one is a d-dimensional Brownian motion living in a
random environment which is Brownian in time and homogeneous in space. The
second is a continuous-time random walk on the lattice Z^d, in a random
environment with similar properties as in continuous space. The case of a
space-time white noise environment can be acheived in this second setting. By
means of some Gaussian tools, we estimate the free energy of these models at
low temperature, and give some further information on the strong disorder
regime of the objects under consideration.

710.0944 | Local SUSY-breaking minima in N_f=N_c SQCD? | We study non-supersymmetric minima in N_f=N_c SQCD conjectured by
Intriligator, Seiberg and Shih (ISS). We show that the existence of such minima
depends on the signs of three non-calculable parameters and that no evidence
can be inferred by deforming the theory. We illustrate this by demonstrating
that the conjectured minimum is destabilized in a different deformation of

710.0945 | Thermodynamics and heavy-quark free energies at finite temperature and
density with two flavors of improved Wilson quarks | Thermodynamics of two-flavor QCD at finite temperature and density is studied
on a $16^3 \times 4$ lattice, using a renormalization group improved gauge
action and the clover improved Wilson quark action. In the simulations along
lines of constant $m_{\rm PS}/m_{\rm V}$, we calculate the Taylor expansion
coefficients of the heavy-quark free energy with respect to the quark chemical
potential ($\mu_q$) up to the second order. By comparing the expansion
coefficients of the free energies between quark($Q$)and antiquark($\bar{Q}$),
and between $Q$ and $Q$, we find a characteristic difference at finite $\mu_q$
due to the first order coefficient of the Taylor expansion. We also calculate
the quark number and isospin susceptibilities, and find that the second order
coefficient of the quark number susceptibility shows enhancement around the
pseudo-critical temperature.

710.0947 | Time dilation of a bound half-fluxon pair in a long Josephson junction
with a ferromagnetic insulator | The fluxon dynamics in a long Josephson junction with a ferromagnetic
insulating layer is investigated. It is found that the Josephson phase obeys a
double sine-Gordon equation involving a bound pi fluxon solution, and the
internal oscillations of the bound pair acting as a clock exhibit Lorentz
reductions in their frequencies regarded as a relativistic effect in the time
domain, i.e., time dilation. This is the complement to the Lorentz contraction
of fluxons with no clock. A possible observation scheme is also discussed.

710.0948 | ppK- bound states from Skyrmions | The bound kaon approach to the strangeness in the Skyrme model is applied to
investigating the possibility of deeply bound $ppK^-$ states. We describe the
$ppK^-$ system as two-Skyrmion around which a kaon field fluctuates. Each
Skyrmion is rotated in the space of SU(2) collective coordinate. The rotational
motions are quantized to be projected onto the spin-singlet proton-proton
state. We derive the equation of motion for the kaon in the background field of
two Skyrmions at fixed positions. From the numerical solution of the equation
of motion, it is found that the energy of $K^-$ can be considerably small, and
that the distribution of $K^-$ shows molecular nature of the $ppK^-$ system.
For this deep binding, the Wess-Zumino-Witten term plays an important role. The
total energy of the $ppK^-$ system is estimated in the Born-Oppenheimer
approximation. The binding energy of the $ppK^-$ state is $B.E.\simeq 126$ MeV.

dot | We consider spin and orbital Kondo effect in a parallel arrangement of two
strongly electrostatically coupled quantum dots. Increasing the exchange of
electrons between the dots through the attached leads induces a smooth
crossover between SU(4) spin- and orbital Kondo effect and SU(2) spin Kondo
effect. Being the same for the SU(4) and SU(2) symmetry points, the Kondo
temperature drops slightly in the intermediate regime. Experimentally, two
kinds of Kondo effect can be discriminated by the sensitivity to the
suppression of the spin Kondo effect by Zeeman field. The dependence of the
Kondo temperature and of the differential conductance on the strength of
electronic exchange through the leads and Zeeman field is analyzed in detail.

all geodesics are closed then there are infinitely many simple closed
geodesics. This proof is based on the geodesic return map and the theory of
topological dynamics. From important results of Green, Grove and Gromoll one
can conclude the theorem.

710.0952 | Generalized Curvature and Ricci Tensors for a Higher Spin Potential and
the Trace Anomaly in External Higher Spin Fields in AdS_{4} Space | The curvature of a higher spin potential as constructed in a previous article
of the same authors arXiv:0705.3528 is applied to the analysis of the
linearized trace anomaly obtained from the quadratic part of the effective
action for a conformally coupled scalar with linearized interaction with the
external higher spin fields arXiv:hep-th/0602067. The spin is restricted to
four to profit from technical simplifications but without reducing the problem
in principle. The issue includes the calculation of all Ricci tensors as
multiple traces of the curvature, the derivation of all primary and secondary
Bianchi identities, expressing all Ricci tensors as differential operators
applied to the Fronsdal term, calculating the Weyl variation of these, and
showing finally that Weyl variations of integrals over contracted squares of
Ricci tensors can be used to eliminate the anomaly completely. This peculiarity
is discussed in detail. As tools we use the formalism of bisymmetric tensor
fields whose space is equipped with a local bilinear invariant form, the
*-form.
