709.2235 | Bound diquarks and their Bose-Einstein condensation in strongly coupled
quark matter | We explore the formation of diquark molecules and their Bose-Einstein
condensation (BEC) in the phase diagram of three-flavor quark matter at nonzero
temperature, T, and quark chemical potential, mu. Using a quark model with a
four-fermion interaction, we identify possible diquark excitations as poles of
the microscopically computed diquark propagator. The quark masses are obtained
by solving a dynamical equation for the chiral condensate and are found to
determine the stability of the diquark excitations. The stability of diquark
excitations is investigated in the T-mu plane for different values of the
diquark coupling strength. We find that bound diquark molecules appear at small
quark chemical potentials at intermediate coupling and that BEC of non-strange
diquark molecules occurs if the attractive interaction between quarks is
sufficiently strong.

709.2237 | An efficient source of continuous variable polarisation entanglement | We have experimentally demonstrated the efficient creation of highly
entangled bipartite continuous variable polarisation states. Exploiting an
optimised scheme for the production of squeezing using the Kerr non-linearity
of a glass fibre we generated polarisation squeezed pulses with a mean
classical excitation in S3. Polarisation entanglement was generated by
interfering two independent polarisation squeezed fields on a symmetric beam
splitter. The resultant beams exhibit strong quantum noise correlations in the
dark S1 - S2 polarisation plane. To verify entanglement generation, we
characterised the quantum correlations of the system for two different sets of
conjugate Stokes parameters. The quantum correlations along the squeezed and
the anti-squeezed Stokes parameters were observed to be -4.1 +/- 0.3 dB and
-2.6 +/- 0.3 dB below the shot noise level respectively. The degree of
correlations was found to depend critically on the beam splitting ratio of the
entangling beam splitter. Carrying out measurements on a different set of
conjugate Stokes parameters, correlations of -3.6 +/- 0.3 dB and -3.4 +/- 0.3
dB have been observed. This result is more robust against asymmetries in the
entangling beam splitter, even in the presence of excess noise.

709.2238 | Quaternionen and Geometric Algebra (Quaternionen und Geometrische
Algebra) | In the last one and a half centuries, the analysis of quaternions has not
only led to further developments in mathematics but has also been and remains
an important catalyst for the further development of theories in physics. At
the same time, Hestenes geometric algebra provides a didactically promising
instrument to model phenomena in physics mathematically and in a tangible
manner. Quaternions particularly have a catchy interpretation in the context of
geometric algebra which can be used didactically. The relation between
quaternions and geometric algebra is presented with a view to analysing its
didactical possibilities.

709.224 | Shifted polynomials in a convection problem | The onset of convection in a horizontal layer of fluid heated from below in
the presence of a gravity field varying across the layer is investigated. The
eigenvalue problem governing the linear stability of the mechanical equilibria

709.2241 | Influence of particle shape on shear stress in granular media | We analyze the contact and force networks in a dense confined packing of
pentagonal particles simulated by means of the contact dynamics method. The
particle shape effect is evidenced by comparing the data from pentagon packing
and from a packing with identical characteristics except for the circular shape
of the particles. A surprising observation is that the pentagon packing
develops a lower structural anisotropy than the disk packing. We show in this
work that this weakness is compensated by a higher force anisotropy that leads
to enhanced shear strength of the pentagon packing. With the polygonal shape of
the particles, the strong force chains are mostly composed of edge-to-edge
contacts with a marked zig-zag aspect.

709.2243 | Rate Determining Factors in Protein Model Structures | Previous research has shown a strong correlation of protein folding rates to
the native state geometry, yet a complete explanation for this dependence is
still lacking. Here we study the rate-geometry relationship with a simple
statistical physics model, and focus on two classes of model geometries,
representing ideal parallel and antiparallel structures. We find that the
logarithm of the rate shows an almost perfect linear correlation with the

709.2244 | A numerical finite size scaling approach to many-body localization | We develop a numerical technique to study Anderson localization in
interacting electronic systems. The ground state of the disordered system is
calculated with quantum Monte-Carlo simulations while the localization
properties are extracted from the ``Thouless conductance'' $g$, i.e. the
curvature of the energy with respect to an Aharonov-Bohm flux. We apply our
method to polarized electrons in a two dimensional system of size $L$. We
recover the well known universal $\beta(g)=\rm{d}\log g/\rm{d}\log L$ one
parameter scaling function without interaction. Upon switching on the
interaction, we find that $\beta(g)$ is unchanged while the system flows toward
the insulating limit. We conclude that polarized electrons in two dimensions
stay in an insulating state in the presence of weak to moderate
electron-electron correlations.

709.2246 | Chiral Phase Transition beyond Mean Field Approximation | Based on the analogy between the Nambu--Jona-Lasinio model of chiral symmetry
breaking and the BCS theory of superconductivity, we investigate the effect of
$\bar q q$ pair fluctuations on the chiral phase transition. We include
uncondensed $\bar q q$ pairs at finite temperature and chemical potential in a
self-consistent T-matrix formalism, the so-called $G_0 G$ scheme. The pair

model | The authors address the problem of downhill protein folding in the framework
of a simple statistical mechanical model, which allows an exact solution for
the equilibrium and a semianalytical treatment of the kinetics. Focusing on
protein 1BBL, a candidate for downhill folding behavior, and comparing it to
the WW domain of protein PIN1, a two-state folder of comparable size, the
authors show that there are qualitative differences in both the equilibrium and
kinetic properties of the two molecules. However, the barrierless scenario
which would be expected if 1BBL were a true downhill folder is observed only at
low enough temperature.

709.2249 | Heegaard Splittings of Twisted Torus Knots | Little is known on the classification of Heegaard splittings for hyperbolic
3-manifolds. Although Kobayashi gave a complete classification of Heegaard
splittings for the exteriors of 2-bridge knots, our knowledge of other classes
is extremely limited. In particular, there are very few hyperbolic manifolds
that are known to have a unique minimal genus splitting. Here we demonstrate
that an infinite class of hyperbolic knot exteriors, namely exteriors of
certain "twisted torus knots" originally studied by Morimoto, Sakuma and
Yokota, have a unique minimal genus Heegaard splitting of genus two. We also
conjecture that these manifolds possess irreducible yet weakly reducible
splittings of genus three. There are no known examples of such Heegaard
splittings.
| math.GT | little is known on the classification of heegaard splittings for hyperbolic 3manifolds although kobayashi gave a complete classification of heegaard splittings for the exteriors of 2bridge knots our knowledge of other classes is extremely limited in particular there are very few hyperbolic manifolds that are known to have a unique minimal genus splitting here we demonstrate that an infinite class of hyperbolic knot exteriors namely exteriors of certain twisted torus knots originally studied by morimoto sakuma and yokota have a unique minimal genus heegaard splitting of genus two we also conjecture that these manifolds possess irreducible yet weakly reducible splittings of genus three there are no known examples of such heegaard splittings | [['little', 'is', 'known', 'on', 'the', 'classification', 'of', 'heegaard', 'splittings', 'for', 'hyperbolic', '3manifolds', 'although', 'kobayashi', 'gave', 'a', 'complete', 'classification', 'of', 'heegaard', 'splittings', 'for', 'the', 'exteriors', 'of', '2bridge', 'knots', 'our', 'knowledge', 'of', 'other', 'classes', 'is', 'extremely', 'limited', 'in', 'particular', 'there', 'are', 'very', 'few', 'hyperbolic', 'manifolds', 'that', 'are', 'known', 'to', 'have', 'a', 'unique', 'minimal', 'genus', 'splitting', 'here', 'we', 'demonstrate', 'that', 'an', 'infinite', 'class', 'of', 'hyperbolic', 'knot', 'exteriors', 'namely', 'exteriors', 'of', 'certain', 'twisted', 'torus', 'knots', 'originally', 'studied', 'by', 'morimoto', 'sakuma', 'and', 'yokota', 'have', 'a', 'unique', 'minimal', 'genus', 'heegaard', 'splitting', 'of', 'genus', 'two', 'we', 'also', 'conjecture', 'that', 'these', 'manifolds', 'possess', 'irreducible', 'yet', 'weakly', 'reducible', 'splittings', 'of', 'genus', 'three', 'there', 'are', 'no', 'known', 'examples', 'of', 'such', 'heegaard', 'splittings']] | [-0.26175313631496727, 0.14576790080289875, -0.07791134567066495, 0.17348635887901764, -0.15268983311086362, -0.23261305888965061, -0.04395514373858792, 0.40329725385527126, -0.21641848104939396, -0.34058305157148944, 0.09063774353957602, -0.24455197088328923, -0.14930208275057208, 0.2523874577267894, -0.1818927755063799, -0.006064214768619942, 0.1332695376976127, 0.035840346344879696, -0.10969162781631374, -0.2818199914368701, 0.4398363225128768, -0.12162044789251272, 0.12979873964546382, 0.15798422226466105, 0.11886519493418746, -0.11433860974752211, 0.029913188943672658, 0.0028754469614276396, -0.20865503632785476, 0.09764844928369192, 0.3226019188171319, -0.007441760610423184, 0.09449304338652707, -0.30247252697258126, -0.17115187869889528, 0.16925019000544644, 0.14412882789370737, 0.02503754447181044, -0.08945164912984183, -0.23573688015208713, 0.08211494391019057, -0.13643221429083496, -0.17111305566504598, -0.10279076002604727, 0.03591177562235056, -0.0016831674687896989, -0.06071863961239744, -0.025114523889507318, 0.13392311138367013, 0.14331519853190652, 0.04429055882168801, -0.1842627638751375, -0.09124708116827865, 0.15923009981218325, 0.05737979661457108, 0.04458820876399321, -0.011041034881990137, -0.11684943708990302, -0.15450684450167632, 0.34836327604716644, -0.05557220063721096, -0.26453638203176005, 0.2094246258774157, -0.10531864936014504, -0.25093635722545776, 0.23577989888976195, 0.05228903384444753, 0.19830889931680368, -0.029369178269657174, 0.14495947339569934, -0.16988599874145752, 0.10301995776327592, 0.16048471371427045, -0.03161903472937411, 0.134691836395567, 0.06375482534141545, 0.10003317794014167, 0.13709586870027124, -0.00581036956905986, -0.03599283652147278, -0.2664324180223048, -0.18866675476809697, -0.12937049450452573, 0.1929979639161112, -0.08563599154240364, -0.24389946650730313, 0.4077375850091422, -0.07015189599977541, 0.12180199361838666, 0.16972605944959337, 0.2528923895027089, -0.03515499649750252, 0.07285431991164971, 0.12182801947762657, 0.19887735438533127, 0.211681524460021, -0.11880431302207788, -0.10862044499819083, -0.051290978465528624, 0.2063660420161406] |
709.225 | Crystal and magnetic structures of the spin-trimer compounds Ca3 Cu3xNix
(PO4)4 (x=0,1,2) | Crystal and magnetic structures of a series of novel quantum spin trimer
system Ca3Cu3xNix(PO4)4 (x=0,1,2) were studied by neutron powder diffraction at
the temperatures 1.5-290 K. The composition with one Ni per trimer (x=1) has a
monoclinic structure (space group P 21 /a, no. 14) with the unit cell
parameters a = 17.71 A, b = 4.89 A, c = 8.85 A and = 123.84 deg at T=290 K. The
(x=2) composition crystallizes in the C 2/c space group (no. 15) with the
doubled unit cell along c-axis. Each trimer is formed by two crystallographic
positions: one in the middle and the second one at the ends of the trimer. We
have found that the middle position is occupied by the Cu2+, whereas the end
positions are equally populated with the Cu2+ and Ni2+ for (x=1) while in the
(x=2) the trimers were found to be of only one type Ni-Cu-Ni. Below TN = 20 K
the (x=2) compound shows an antiferromagnetic ordering with propagation vector
star {[1/2,1/2, 0], [-1/2,1/2, 0]} The magnetic structure is very well
described with the irreducible representation tau22 using both arms of the star
{k} with the magnetic moments 1.89(1) muB and 0.62(2) muB for Ni2+ and Cu2+
ions, respectively. We note that our powder diffraction data cannot be fitted
by a model containing only one arm of the propagation vector star. The
Cu/Ni-spins form both parallel and antiparallel configurations in the different
trimers, implying substantial effect of the inter-trimer interaction on the
overall magnetic structure.

709.2251 | Multiterminal Nanowire Junctions of Silicon: A Theoretical Prediction of
Atomic Structure and Electronic Properties | Using empirical scheme, atomic structure of a new exotic class of silicon
nanoclusters was elaborated upon the central icosahedral core (Si-IC) and
pentagonal petals (Si-PP) growing from Si-IC vertexes. It was shown that
Si-IC/Si-PP interface formation is energetically preferable. Some experimental
observations of silicon nanostructures can be explained by presence of the
proposed objects. The Extended Huckel Theory electronic structure calculations

709.2252 | Otiy: Loactors tracking nodes | We propose Otiy, a node-centric location service that limits the impact of
location updates generate by mobile nodes in IEEE802.11-based wireless mesh
networks. Existing location services use node identifiers to determine the
locator (aka anchor) that is responsible for keeping track of a node's
location. Such a strategy can be inefficient because: (i) identifiers give no
clue on the node's mobility and (ii) locators can be far from the
source/destination shortest path, which increases both location delays and
bandwidth consumption. To solve these issues, Otiy introduces a new strategy
that identifies nodes to play the role of locators based on the likelihood of a
destination to be close to these nodes- i.e., locators are identified depending
on the mobility pattern of nodes. Otiy relies on the cyclic mobility patterns
of nodes and creates a slotted agenda composed of a set of predicted locations,
defined according to the past and present patterns of mobility. Correspondent
nodes fetch this agenda only once and use it as a reference for identifying
which locators are responsible for the node at different points in time. Over a
period of about one year, the weekly proportion of nodes having at least 50% of
exact location predictions is in average about 75%. This proportion increases
by 10% when nodes also consider their closeness to the locator from only what
they know about the network.

709.2253 | Gravitational waves originated before compactification in Kaluza-Klein
theory | We investigate the propagation of multidimensional gravitational waves
generated before compactification and observes today as 4-dimensional
gravitational waves and gauge fields by generalizing the investigation of
Alesci and Montani(AM) to the case where the internal space is an n-sphere. We
also derive the 4-dimensional forms of the multidimensional harmonic gauge
condition. The primary difference from the case of AM comes from the effect of
curvature of the internal space which prevent the space to be static. The other
effects are explicitly shown for propagation of the waves in our 4-dimensional
spacetime. Static internal space exists if multidimensional

709.2256 | Confinement-induced enhancement of diffusiophoretic forces on
self-propellers | We study the effect of spatial confinement on the strength of propulsive
diffusiophoretic forces acting on a particle that generates density gradients
by exploiting the chemical free energy of its environment. Using a recently
proposed simple model of a self-propelling device driven by chemical reactions
taking place on some parts of its surface, we demonstrate that the force

form is less nice looking and simple than that latter derived by Droste and

describing the gravitational field of a massive point particle.

709.226 | OVII and OVIII line emission in the diffuse soft X-ray background:
heliospheric and galactic contributions | We study the 0.57 keV (O VII triplet) and 0.65 keV (O VIII) diffuse emission
generated by charge transfer collisions between solar wind (SW) oxygen ions and
interstellar H and He neutral atoms in the inner Heliosphere. These lines which
dominate the 0.3-1.0 keV energy interval are also produced by hot gas in the
galactic halo (GH) and possibly the Local Interstellar Bubble (LB). We
developed a time-dependent model of the SW Charge-Exchange (SWCX) X-ray
emission, based on the localization of the SW Parker spiral at each instant. We
include input SW conditions affecting three selected fields, as well as
shadowing targets observed with XMM-Newton, Chandra and Suzaku and calculate
X-ray emission fot O VII and O VIII lines. We determine SWCX contamination and
residual emission to attribute to the galactic soft X-ray background. We obtain
ground level intensities and/or simulated lightcurves for each target and
compare to X-ray data. The local 3/4 keV emission (O VII and O VIII) detected
in front of shadowing clouds is found to be entirely explained by the CX
heliospheric emission. No emission from the LB is needed at these energies.
Using the model predictions we subtract the heliospheric contribution to the
measured emission and derive the halo contribution. We also correct for an
error in the preliminary analysis of the Hubble Deep Field North (HDFN).

709.2264 | Looking for signals of New Physics in the Top quark samples with the CDF
detector | Twelve years after the discovery of the Top quark, the CDF detector has
collected large samples of tt-bar events with integrated luminosities up to
1-1.7 fb^-1, where we are able to probe our knowledge of the Standard Model Top
quark. This article will focuss on those analysis results dedicated to find new
physics in the Top quark production: measurement of relative fractions of Top
pair production mechanisms, searches for a massive resonant state decaying to
tt-bar pairs as well as a heavy Top-like quark decaying as the Standard Model
Top quark. Besides its production, the Top quark decay is also an interesting
probe to find Physics Beyond the Standard Model by measuring possibly anomalous
values of the helicity fractions of the W boson in the decay t-->W(-->l+v_l)b

709.2265 | Discovery of very high-energy gamma-ray emission from the LBL object BL
Lacertae | The low-frequency peaked BL Lac (LBL) object BL Lacertae was observed with
the MAGIC telescope from 2005 August to December (22.2 hr), and from 2006 July
to September (26.0 hr). A very high energy (VHE) gamma-ray signal was
discovered with a 5.1 sigma excess in the 2005 data. Above 200 GeV, an integral
flux of (0.6+-0.2)x10e-11 m-2 s-1 was measured, corresponding to approximately
3% of the Crab flux. The differential spectrum between 150 and 900 GeV is
rather steep, with a photon index of -3.6+-0.5. The light curve shows no
significant variability during the observations in 2005. For the first time a
clear detection of VHE gamma-ray emission from an LBL object was obtained. The
2006 data show no significant excess. This drop in flux follows the observed
trend in optical activity

709.2268 | Twisting Flux Tubes as a cause of Micro-Flaring Activity | High-cadence optical observations of an H-alpha blue-wing bright point near
solar AR NOAA 10794 are presented. The data were obtained with the Dunn Solar
Telescope at the National Solar Observatory/Sacramento Peak using a newly
developed camera system, the Rapid Dual Imager. Wavelet analysis is undertaken
to search for intensity-related oscillatory signatures, and periodicities
ranging from 15 to 370 s are found with significance levels exceeding 95%.
During two separate microflaring events, oscillation sites surrounding the
bright point are observed to twist. We relate the twisting of the oscillation
sites to the twisting of physical flux tubes, thus giving rise to reconnection
phenomena. We derive an average twist velocity of 8.1 km/s and detect a peak in
the emitted flux between twist angles of 180 and 230 degrees.

709.2269 | A Comparison of Mixed-Higgs Scenarios In the NMSSM and the MSSM | We study scenarios in the minimal and next-to minimal supersymmetric models
in which the lightest CP-even Higgs boson can have mass below the 114 GeV
standard model LEP limit by virtue of reduced ZZ coupling due to substantial
mixing among the Higgs bosons. We pay particular attention to the size of
corrections from superpartners needed for these scenarios to be viable and
point to boundary conditions at large scales which lead to these scenarios
while at the same time keeping electroweak fine tuning modest in size. We find
that naturalness of electroweak symmetry breaking in the mixed-Higgs scenarios
of both models points to the same region of soft supersymmetry breaking terms,
namely those leading to large mixing in the stop sector at the electroweak
scale, especially if we also require that the lightest CP-even Higgs explains
the Higgs-like LEP events at about 98 GeV.

709.2271 | First-principles Study of Physisorption of Nucleic Acid Bases on
Small-Diameter Carbon Nanotube | We report the results of our first-principles study based on density
functional theory on the interaction of the nucleic acid base molecules adenine
(A), cytosine (C), guanine (G), thymine (T), and uracil (U), with a
single-walled carbon nanotube (CNT). Specifically, the focus is on the
physisorption of base molecules on the outer wall of a (5,0) metallic CNT
possessing one of the smallest diameters possible. Compared to CNTs with large
diameters, the physisorption energy is found to be reduced in the
high-curvature case. The base molecules exhibit significantly different
interaction strengths, and the calculated binding energies follow the hierarchy
G > A > T > C > U, which appears to be independent of the tube curvature. The
stabilizing factor in the interaction between the base molecule and CNT is
dominated by the molecular polarizability that allows a weakly attractive
dispersion force to be induced between them. The present study provides an
improved understanding of the role of the base sequence in deoxyribonucleic
acid (DNA) or ribonucleic acid (RNA) on their interactions with carbon
nanotubes of varying diameters.

709.2273 | Multi-component strongly attractive Fermi gas: a color superconductor in
a one-dimensional harmonic trap | Recent advances in ultra-cold atomic Fermi gases make it possible to achieve
a fermionic superfluid with multiple spin components. In this context, any
mean-field description is expected to fail, owing to the presence of tightly
bound clusters or molecules that consist of more than two particles. Here we
present a detailed study of a strongly interacting multi-component Fermi gas in
a highly elongated or quasi-one-dimensional harmonic trap, which could be
readily obtained in experiment. By using the exact Bethe ansatz solution and a
local density approximation treatment of the harmonic trap, we investigate the
equation of state of the multi-component Fermi gas in both a homogeneous and
trapped environment, as well as the density profiles and low-energy collective
modes. The binding energy of multi-component bound clusters is also given. We
show that there is a peak in the collective mode frequency at the critical

Geometrical Frustration | Structural phase transition accompanying with quadrupolar ordering in DyB4
with Shastry-Sutherland type geometrical frustration has been studied by X-ray
diffraction. Previous study [D. Okuyama et al.: J. Phys. Soc. Jpn. 74 (2005)
2434.] using resonant X-ray scattering revealed short-range ordering of the
Ozx-type quadrupolar moments and the c-plane component of the magnetic moments
in addition to long-range ordering of the c-axis component of the magnetic
moments. The present report focuses on the lattice distortion below the
quadrupolar ordering temperature at TN2=12.7 K. The (0 0 l=integer) fundamental
lattice reflection splits into four peaks along the h and k directions and the
(h=even 0 0) reflection becomes broad along the l direction. This indicates
that a structural transition from tetragonal to monoclinic takes place below
TN2 together with the ordering of the quadrupolar moments.

709.2275 | SPINSTARS at low metallicities | The main effect of axial rotation on the evolution of massive PopIII stars is
to trigger internal mixing processes which allow stars to produce significant
amounts of primary nitrogen 14 and carbon 13. Very metal poor massive stars
produce much more primary nitrogen than PopIII stars for a given initial mass
and rotation velocity. The very metal poor stars undergo strong mass loss
induced by rotation. One can distinguish two types of rotationnaly enhanced
stellar winds: 1) Rotationally mechanical winds occurs when the surface
velocity reaches the critical velocity at the equator, {\it i.e.} the velocity
at which the centrifugal acceleration is equal to the gravity; 2) Rotationally
radiatively line driven winds are a consequence of strong internal mixing which
brings large amounts of CNO elements at the surface. This enhances the opacity
and may trigger strong line driven winds. These effects are important for an
initial value of $\upsilon/\upsilon_{\rm crit}$ of 0.54 for a 60 M$_\odot$ at
$Z=10^{-8}$, {\it i.e.} for initial values of $\upsilon/\upsilon_{\rm crit}$
higher than the one ($\sim$0.4) corresponding to observations at solar $Z$.
These two effects, strong internal mixing leading to the synthesis of large
amounts of primary nitrogen and important mass losses induced by rotation,
occur for $Z$ between about 10$^{-8}$ and 0.001. For metallicities above 0.001
and for reasonable choice of the rotation velocities, internal mixing is no
longer efficient enough to trigger these effects.

709.2276 | Exact results of the quantum phase transition for the topological order | In this paper a duality between the d=2 Wen-plaquette model in a transverse
field and the d=1 Ising model in a transverse field is used to learn the nature
of the quantum phase transition (QPT) between a spin-polarized phase and a
topological ordered state with the string-net condensation. The QPT is not
induced by spontaneous symmetry breaking and there are no conventional
Landau-type local order parameters. Instead the string-like non-local order
parameters are introduced to describe the QPT. In particular, the duality
character between the open-string and closed string for the QPT are explored.

superfield formalism | We demonstrate that the nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and
anti-BRST symmetry invariance of the Lagrangian density of a four (3 +
1)-dimensional (4D) non-Abelian 1-form gauge theory with Dirac fields can be
captured within the framework of the superfield approach to BRST formalism. The
above 4D theory, where there is an explicit coupling between the non-Abelian
1-form gauge field and the Dirac fields, is considered on a (4, 2)-dimensional
supermanifold, parameterized by the bosonic 4D space-time variables and a pair
of Grassmannian variables. We show that the Grassmannian independence of the
super Lagrangian density, expressed in terms of the (4, 2)-dimensional
superfields, is a clear signature of the presence of the (anti-)BRST invariance
in the original 4D theory.

709.2278 | Observation of Goos-H\"{a}nchen shifts in metallic reflection | We report the first observation of the Goos-H$\rm \ddot{\textbf{a}}$nchen
shift of a light beam incident on a metal surface. This phenomenon is
particularly interesting because the Goos-H$\rm \ddot{\textbf{a}}$nchen shift
for $p$ polarized light in metals is negative and much bigger than the positive
shift for $s$ polarized light. The experimental result for the measured shifts
as a function of the angle of incidence is in excellent agreement with
theoretical predictions. In an energy-flux interpretation, our measurement

as a tunable source of photoluminescence in nanodevices | We propose a new variety of silicon quantum dots containing fullerene-derived
hollows of nearly arbitrary symmetry. Conglomerate structures are designed by
connecting the quantum dots through two kinds of junctions. The quantum
confinement effect is investigated using semiempirical quantum-mechanical
method. It is shown that within each family of quantum dots, the band gap and
the stability are inversely proportional to the particle effective size.
Quantum dots inherit a wide variety of structural and symmetry properties from
their parent fullerenes. The conglomerates confine electrons like
quasi-molecules with a peculiar electronic structure related to the junctions.
Quantum dots and their conglomerates can host guest atoms in their hollows and
therefore present a new promising type of tunable photoluminescent
nanomaterials.

we show how to associate a groupoid $\mathfrak{G}_{\mathcal{G}}$ to an
ultragraph $\mathcal{G}$ in such a way that the $C^*$-algebra of
$\mathfrak{G}_{\mathcal{G}}$ is canonically isomorphic to Tomforde's
$C^*$-algebra $C^*(\mathcal{G})$. The groupoid $\mathfrak{G}_{\mathcal{G}}$ is
built from an inverse semigroup $S_{\mathcal{G}}$ naturally associated to
$\mathcal{G}$.

moonlight. TeV gamma-ray signals from the Crab nebula were detected with the
MAGIC telescope during periods when the Moon was above the horizon and during

the telescope performance by studying the effect of the moonlight on the

709.2284 | On convergence of generators of equilibrium dynamics of hopping
particles to generator of a birth-and-death process in continuum | We deal with two following classes of equilibrium stochastic dynamics of
infinite particle systems in continuum: hopping particles (also called Kawasaki
dynamics), i.e., a dynamics where each particle randomly hops over the space,
and birth-and-death process in continuum (or Glauber dynamics), i.e., a
dynamics where there is no motion of particles, but rather particles die, or
are born at random. We prove that a wide class of Glauber dynamics can be
derived as a scaling limit of Kawasaki dynamics. More precisely, we prove the
convergence of respective generators on a set of cylinder functions, in the
$L^2$-norm with respect to the invariant measure of the processes. The latter
measure is supposed to be a Gibbs measure corresponding to a potential of pair
interaction, in the low activity-high temperature regime. Our result
generalizes that of [Finkelshtein D.L. et al., to appear in Random Oper.

709.2285 | Critically rotating stars in binaries - an unsolved problem - | In close binaries mass and angular momentum can be transferred from one star
to the other during Roche-lobe overflow. The efficiency of this process is not
well understood and constitutes one of the largest uncertainties in binary
evolution.
One of the problems lies in the transfer of angular momentum, which will spin
up the accreting star. In very tight systems tidal friction can prevent
reaching critical rotation, by locking the spin period to the orbital period.
Accreting stars in systems with orbital periods larger than a few days reach
critical rotation after accreting only a fraction of their mass, unless there
is an effective mechanism to get rid of angular momentum. In low mass stars
magnetic field might help. In more massive stars angular momentum loss will be
accompanied by strong mass loss. This would imply that most interacting
binaries with initial orbital periods larger than a few days evolve very
non-conservatively.
In this contribution we wish to draw attention to the unsolved problems
related to mass and angular momentum transfer in binary systems. We do this by
presenting the first results of an implementation of spin up by accretion into
the TWIN version of the Eggleton stellar evolution code.

709.2286 | A Poincar\'e-Birkhoff-Witt criterion for Koszul operads | The aim of this article is to give a criterion, generalizing the criterion
introduced by Priddy for algebras, to verify that an operad is Koszul. We
define the notion of a Poincare-Birkhoff-Witt basis in the context of operads.
Then we show that an operad having a Poincare-Birkhoff-Witt basis is Koszul.
Besides, we obtain that the Koszul dual operad has also a
Poincare-Birkhoff-Witt basis. We check that the classical examples of Koszul
operads (commutative, associative, Lie) have a Poincare-Birkhoff-Witt basis.
| math.AT | the aim of this article is to give a criterion generalizing the criterion introduced by priddy for algebras to verify that an operad is koszul we define the notion of a poincarebirkhoffwitt basis in the context of operads then we show that an operad having a poincarebirkhoffwitt basis is koszul besides we obtain that the koszul dual operad has also a poincarebirkhoffwitt basis we check that the classical examples of koszul operads commutative associative lie have a poincarebirkhoffwitt basis | [['the', 'aim', 'of', 'this', 'article', 'is', 'to', 'give', 'a', 'criterion', 'generalizing', 'the', 'criterion', 'introduced', 'by', 'priddy', 'for', 'algebras', 'to', 'verify', 'that', 'an', 'operad', 'is', 'koszul', 'we', 'define', 'the', 'notion', 'of', 'a', 'poincarebirkhoffwitt', 'basis', 'in', 'the', 'context', 'of', 'operads', 'then', 'we', 'show', 'that', 'an', 'operad', 'having', 'a', 'poincarebirkhoffwitt', 'basis', 'is', 'koszul', 'besides', 'we', 'obtain', 'that', 'the', 'koszul', 'dual', 'operad', 'has', 'also', 'a', 'poincarebirkhoffwitt', 'basis', 'we', 'check', 'that', 'the', 'classical', 'examples', 'of', 'koszul', 'operads', 'commutative', 'associative', 'lie', 'have', 'a', 'poincarebirkhoffwitt', 'basis']] | [-0.1565858502459677, -0.0467841045166914, -0.14200032966011028, 0.14972802523016646, -0.18656585087315947, -0.13931894490401012, -0.056569586225042615, 0.3761260064342354, -0.42986803805997853, -0.14032153868929872, 0.12013504148425558, -0.1484232094091705, -0.23758851088394847, 0.14216731479273567, -0.2449071388337997, -0.09987305759605539, 0.07758018610515643, 0.09758268475909776, -0.09289379336552907, -0.2955738914588207, 0.4613924776262875, 0.10006756204345464, 0.2063916802076222, 0.016111448271600885, 0.10587510806666775, 0.00020407477417324162, -0.007013518501756878, -0.01059291940889781, -0.21841095250189788, 0.1341809047713192, 0.34482991846301886, 0.11179207553026042, 0.20189593682843673, -0.37583273080991036, -0.023760757615341792, 0.171214505664627, 0.1536489279551691, 0.07503599876278563, -0.06728131779104093, -0.19725591617435972, 0.11846469664545375, -0.3154273952027382, -0.13310515896499722, -0.1320868560313424, 0.12905641550881952, -0.01897516187657661, -0.28316594373812026, -0.043884346701125204, 0.1525084388595593, 0.174476277248203, -0.10019505415347559, -0.0673597443000048, -0.1320196692920231, 0.02826226562190848, -0.10220353896847537, 0.027765002844360055, 0.09287918125621125, -0.054526834309549084, -0.23446169457563398, 0.3286708441056028, -0.021142844759116444, -0.22274119461167463, 0.10458629469894155, -0.14658294434296676, -0.19385459891791584, 0.03255181824563726, -0.061779772957103164, 0.17073325313170162, -0.0966655715380477, 0.21628084422761126, -0.2127565898449172, 0.04188671993398214, 0.12304111362635335, 0.06439631263934713, 0.14656810054579114, 0.1344729733382222, 0.028818077245680026, 0.23653493423156347, 0.0902393026383523, -0.03504643021033534, -0.3304324844922823, -0.2589929642898467, -0.060587552635447135, 0.13941841825984325, -0.12672763037837192, -0.15246479159008852, 0.38067796001140075, 0.19658105411563848, 0.13089274487729313, 0.18601962376998948, 0.18585155076712748, 0.055942849373987205, 0.1339663129205568, -0.03556604917408734, 0.15182610311474698, 0.33800942689192165, 0.01612467231535459, -0.07094906453231845, -0.04403665777048261, 0.30445001131701693] |

709.229 | Mirror Symmetry via Logarithmic Degeneration Data II | This paper continues the authors' program of studying mirror symmetry via log
geometry and toric degenerations, relating affine manifolds with singularities,
log Calabi-Yau spaces, and toric degenerations of Calabi-Yaus. The main focus
of this paper is the calculation of the cohomology of a Calabi-Yau variety
associated to a given affine manifold with singularities B. We show that the
Dolbeault cohomology groups of the Calabi-Yau associated to B are described in
terms of some cohomology groups of sheaves on B, as expected. This is proved
first by calculating the log de Rham and log Dolbeault cohomology groups on the
log Calabi-Yau space associated to B, and then proving a base-change theorem
for cohomology in our logarithmic setting.
As applications, this shows that our mirror symmetry construction via
Legendre duality of affine manifolds results in the usual interchange of Hodge
numbers expected in mirror symmetry, and gives an explicit description of the
monodromy of a smoothing.

709.2291 | Squark Decays in MSSM Under the Cosmological Bounds | We present the numerical investigation of the fermionic two-body decays of
squarks in the Minimal Supersymmetric Standard Model with complex parameters.
In the analysis we particularly take into account the cosmological bounds
imposed by WMAP data. We find that the phase dependences of the decay widths of
the third family squarks, as well as those of the first and second families,
are quite significant which can provide viable probes of additional CP sources.
We plot the CP phase dependences for each fermionic two-body decay channel of
squarks $\tilde q_i$ (i=1,2, q=u,d;c,s;t,b) and speculate about the branching
ratios and total (two-body) decay widths.

from the outer envelope. These winds form a shell, which may ultimately become
a planetary nebula. Many planetary nebulae are highly asymmetric, hinting at
the presence of a binary companion. Some post-Asymptotic Giant Branch objects
are surrounded by torii of crystalline dust, but there is no generally accepted
mechanism for annealing the amorphous grains in the wind to crystals. In this
Letter, we show that the shaping of the wind by a binary companion is likely to
lead to the formation of crystalline dust in the orbital plane of the binary.

709.2293 | Titan's rotational state : The effects of a forced "free" resonant
wobble | In Noyelles et al. (2008, Astron. Astrophys., 478, 959-970), a resonance
involving the wobble of Titan is hinted. This paper studies this scenario and
its consequences. The first step is to build an accurate analytical model that
would help to find the likely resonances in the rotation of every synchronous
body. In this model, I take the orbital eccentricity of the body into account,
as well as its variable inclination with respect to Saturn's equator. Then an
analytical study using the second fundamental model of the resonance is
performed to study the resonance of interest. Finally, I study the dissipative
consequences of this resonance. I find that this resonance may have increased
the wobble of Titan by several degrees. For instance, if Titan's polar momentum
C is equal to 0.355MR_T^2 (M and R_T being respectively Titan's mass and
radius), the wobble might be forced to 41 degrees. Thanks to an original
formula, I find that the dissipation associated with the forced wobble might
not be negligible compared to the contribution of the eccentricity. I also
suspect that, due to the forced wobble, Titan's period of rotation may be
somewhat underestimated by observers. Finally, I use the analytical model
presented in this paper to compute the periods of the free librations of the
four Galilean satellites as well as the Saturnian satellite Rhea. For Io and
Europa, the results are consistent with previous studies. For the other
satellites, the periods of the free librations are respectively 186.37 d, 23.38
y and 30.08 y for Ganymede, 2.44 y, 209.32 y and 356.54 y for Callisto, and
51.84 d, 2.60 y and 3.59 y for Rhea.

709.2297 | New interactions in the dark sector mediated by dark energy | Cosmological observations have revealed the existence of a dark matter
sector, which is commonly assumed to be made up of one particle species only.
However, this sector might be more complicated than we currently believe: there
might be more than one dark matter species (for example two components of cold
dark matter or a mixture of hot and cold dark matter) and there may be new
interactions between these particles. In this paper we study the possibility of
multiple dark matter species and interactions mediated by a dark energy field.
We study both the background and the perturbation evolution in these scenarios.
We find that the background evolution of a system of multiple dark matter
particles (with constant couplings) mimics a single fluid with a time-varying
coupling parameter. However, this is no longer true on the perturbative level.

709.2298 | Hypernuclei and in-medium chiral dynamics | A recently introduced relativistic nuclear energy density functional,
constrained by features of low-energy QCD, is extended to describe the
structure of hypernuclei. The density-dependent mean field and the spin-orbit
potential of a $\Lambda$-hyperon in a nucleus, are consistently calculated
using the SU(3) extension of in-medium chiral perturbation theory. The leading
long-range $\Lambda N$ interaction arises from kaon-exchange and
$2\pi$-exchange with a $\Sigma$-hyperon in the intermediate state. Scalar and
vector mean fields, originating from in-medium changes of the quark
condensates, produce a sizeable {\em short-range} spin-orbit interaction. The
model, when applied to oxygen as a test case, provides a natural explanation
for the smallness of the effective $\Lambda$ spin-orbit potential: an almost
complete cancellation between the background contributions (scalar and vector)
and the long-range terms generated by two-pion exchange.

709.2299 | Gamma-Rays from Decaying Dark Matter | We study the prospects for detecting gamma-rays from decaying Dark Matter
(DM), focusing in particular on gravitino DM in R-parity breaking vacua. Given
the substantially different angular distribution of the predicted gamma-ray
signal with respect to the case of annihilating DM, and the relatively poor (of
order 0.1$^\circ$) angular resolution of gamma-ray detectors, the best strategy
for detection is in this case to look for an exotic contribution to the
gamma-ray flux at high galactic latitudes, where the decaying DM contribution
would resemble an astrophysical extra-galactic component, similar to the one
inferred by EGRET observations. Upcoming experiments such as GLAST and AMS-02
may identify this exotic contribution and discriminate it from astrophysical

709.23 | Testing the galaxy cluster mass-observable relations at z = 1 with
XMM-Newton and Chandra observations of XLSSJ022403.9-041328 | We present an analysis of deep XMM-Newton and Chandra observations of the
z=1.05 galaxy cluster XLSSJ022403.9-041328 (hereafter XLSSC 029), detected in
the XMM-Newton large scale structure survey. Density and temperature profiles
of the X-ray emitting gas were used to perform a hydrostatic mass analysis of
the system. This allowed us to measure the total mass and gas fraction in the
cluster and define overdensity radii R500 and R2500. The global properties of
XLSSC 029 were measured within these radii and compared with those of the local
population. The gas mass fraction was found to be consistent with local
clusters. The mean metal abundance was 0.18 +0.17 -0.15 Zsol, with the cluster
core regions excluded, consistent with the predicted and observed evolution.
The properties of XLSSC 029 were then used to investigate the position of the
cluster on the M-kT, YX-M, and LX-M scaling relations. In all cases the
observed properties of XLSSC 029 agreed well with the simple self-similar
evolution of the scaling relations. This is the first test of the evolution of
these relations at z > 1 and supports the use of the scaling relations in
cosmological studies with distant galaxy clusters.

709.2301 | Constraints on decaying Dark Matter from XMM-Newton observations of M31 | We derive constraints on parameters of the radiatively decaying Dark Matter
(DM) particles, using XMM-Newton EPIC spectra of the Andromeda galaxy (M31).
Using the observations of the outer (5'-13') parts of M31 we improve the
existing constraints. For the case of sterile neutrino DM, combining our
constraints with the latest computation of abundances of sterile neutrino in
the Dodelson-Widrow (DW) scenario, we obtain the lower mass limit m_s < 4 keV,
which is stronger than the previous one m_s < 6 kev, obtained recently by Asaka
et al. (2007) [hep-ph/0612182]. Comparing this limit with the most recent
results on Lyman-alpha forest analysis of Viel et al. (2007) [arXiv:0709.0131]
(m_s > 5.6 kev), we argue that the scenario in which all the DM is produced via
DW mechanism is ruled out. We discuss however other production mechanisms and

709.2302 | First-principles study of ternary fcc solution phases from special
quasirandom structures | In the present work, ternary Special Quasirandom Structures (SQSs) for a fcc
solid solution phase are generated at different compositions,
$x_A=x_B=x_C=\tfrac{1}{3}$ and $x_A=\tfrac{1}{2}$, $x_B=x_C=\tfrac{1}{4}$,
whose correlation functions are satisfactorily close to those of a random fcc
solution. The generated SQSs are used to calculate the mixing enthalpy of the
fcc phase in the Ca-Sr-Yb system. It is observed that first-principles
calculations of all the binary and ternary SQSs in the Ca-Sr-Yb system exhibit
very small local relaxation. It is concluded that the fcc ternary SQSs can
provide valuable information about the mixing behavior of the fcc ternary solid
solution phase. The SQSs presented in this work can be widely used to study the
behavior of ternary fcc solid solutions.

709.2303 | Phase diagram of hole doped two-leg Cu-O ladders | In the weak coupling limit, we establish the phase diagram of a two-leg
ladder with a unit cell containing both Cu and O atoms, as a function of
doping. We use bosonization and design a specific RG procedure to handle the
additional degrees of freedom. Significant differences are found with the
single orbital case; for purely repulsive interactions, a completely massless
quantum critical region is obtained at intermediate carrier concentrations

709.2304 | Pairs of commuting nilpotent matrices, and Hilbert function | Let K be an infinite field and denote by H(n,K) the family of pairs (A,B) of
commuting nilpotent n by n matrices with entries in K. There has been
substantial recent study of the connection between H(n,K) and the fibre H[n] of
the punctual Hilbert scheme of the plane, over an n-fold point of the symmetric
product, by V. Baranovsky, R. Basili, and A. Premet.
We study the stratification of H(n,K) by the Hilbert function of the Artinian
ring K[A,B]. We show that when dim_K K[A,B] = n, then the generic element of
the pencil A+\lambda B, \lambda \in K, has Jordan partition the maximum
partition P(H) whose diagonal lengths are the Hilbert function of K[A,B].
We denote by Q(P) the maximum Jordan partition of a nilpotent A commuting
with a nilpotent B of Jordan partition P. We show that the stable partitions -
those such that Q(P)=P - are those whose parts differ by at least two. In
characteristic zero, the latter is a special case of a result of D. Panyushev.
Our result on pencils shows that Q(P) has decreasing parts. In related work, T.
Kosir and P. Oblak have shown further that Q(P) is itself stable.

Proof of the commutation relations | We explicitly construct two classes of infinitly many commutative operators
in terms of the deformed W-algebra $W_{qt}(sl_N^)$, and give proofs of the
commutation relations of these operators. We call one of them local integrals

709.2307 | The Generalized Uncertainty Principle in (A)dS Space and the
Modification of Hawking Temperature from the Minimal Length | Recently, the Heisenberg's uncertainty principle has been extended to
incorporate the existence of a large (cut-off) length scale in de Sitter or
anti-de Sitter space, and the Hawking temperatures of the Schwarzshild-(anti)
de Sitter black holes have been reproduced by using the extended uncertainty
principle. I generalize the extended uncertainty to the case with an absolute
minimum length and compute its modification to the Hawking temperature. I
obtain a general trend that the generalized uncertainty principle due to the
absolute minimum length ``always'' increases the Hawking temperature, implying
``faster'' decay, which is in conformity with the result in the asymptotically
flat space. I also revisit the ``black hole-string'' phase transition, in the
context of the generalized uncertainty principle.

709.2309 | Evolutionary Catastrophes and the Goldilocks Problem | One of the mainstays of the controversial "rare Earth" hypothesis is the
"Goldilocks problem" regarding various parameters describing a habitable
planet, partially involving the role of mass extinctions and other catastrophic
processes in biological evolution. Usually, this is construed as support for
the uniqueness of the Earth's biosphere and intelligent human life. Here I
argue that this is a misconstrual and that, on the contrary,
observation-selection effects, when applied to catastrophic processes, make it
very difficult for us to discern whether the terrestrial biosphere and
evolutionary processes which created it are exceptional in the Milky Way or
not. In particular, an anthropic overconfidence bias related to the temporal
asymmetry of evolutionary processes appears when we try to straightforwardly
estimate catastrophic risks from the past records on Earth. This agnosticism,
in turn, supports the validity and significance of practical astrobiological
and SETI research.

709.231 | Modelling the SEDs of spiral galaxies | Modelling the UV/optical - infrared/submm SEDs of spiral galaxies observed
with Herschel will be an essential tool to quantitatively interpret these
observations in terms of the present and past star-formation activity of these
systems. In this lecture we describe the SED modelling technique we have
developed, its applications and tests of its predictions. We show that both the
panchromatic SED modelling of individual galaxies and the B-band
attenuation-inclination relation of large statistical samples suggest that
spiral galaxies in the nearby Universe behave as optically thick systems in
their global properties and large-scale distribution of light (central face-on
B-band opacity of approx. 4). However disk galaxies are very inhomogeneous
systems, having both optically thick components (e.g. spiral arms), and
optically thin components (e.g. the interarm regions), the latter making
galaxies transparent to background galaxies.

Within the spontaneously broken electroweak theory the one- and two-loop mass
singularities have been derived to NLL accuracy and expressed as universal
correction factors depending only on the quantum numbers of the external
particles. This talk summarizes the results for massless fermionic processes
and presents new aspects arising in the extension of the corresponding loop
calculations to massive external fermions. As a preliminary result, the Abelian
form factor for massive fermions is given.

709.2312 | Asymptotic estimation of some multiple integrals and the electromagnetic
deuteron form factors at high momentum transfer | A theorem about asymptotic estimation of multiple integral of a special type
is proved for the case when the integrand peaks at the integration domain
bound, but not at a point of extremum. Using this theorem the asymptotic
expansion of the electromagnetic deuteron form factors at high momentum
transfers is obtained in the framework of two-nucleon model in both
nonrelativistic and relativistic impulse approximations. It is found that
relativistic effects slow down the decrease of deuteron form factors and result
in agreement between the relativistic asymptotics and experimental data at high
momentum transfers.

709.2314 | Bound magnetic polarons in the very dilute regime | We study bound magnetic polarons (BMP) in a very diluted magnetic
semiconductor CdMnTe by means of site selective spectroscopy. In zero magnetic
field we detect a broad and asymmetric band with a characteristic spectral
width of about 5 meV. When external magnetic fields are applied a new line
appears in the emission spectrum. Remarkably, the spectral width of this line
is reduced greatly down to 0.24 meV. We attribute such unusual behavior to the
formation of BMP, effected by sizable fluctuations of local magnetic moments.
The modifications of the optical spectra have been simulated by the Monte-Carlo
method and calculated within an approach considering the nearest Mn ion. A
quantitative agreement with the experiment is achieved without use of fitting
parameters. It is demonstrated that the low-energy part of the emission spectra
originates from the energetic relaxation of a complex consisting of a hole and

layers | We examine how the misorientation of a few stacked graphene layers affects
the electronic structure of carbon nanosystems. We present {\it ab initio}
calculations on bi- and trilayer systems to demonstrate that the massless
Fermion behavior typical of single layered graphene is also found in
incommensurate multilayered graphitic systems. We also investigate the
consequences of this property on experimental fingerprints, such as Raman
spectroscopy and scanning tunneling microscopy (STM). Our simulations reveal
that STM images of turbostratic few layer graphite are sensitive to the layer
arrangement. We also predict that resonant raman signal of graphitic samples
are more sensitive to the orientation of the layers than to their number.

709.2316 | The pressure of QED from the two-loop 2PI effective action | We compute the pressure of hot quantum electrodynamics from the two-loop
truncation of the 2PI effective action. Since the 2PI resummation guarantees
gauge-fixing independence only up to the order of the truncation, our result
for the pressure presents a gauge dependent contribution of O(e^4). We
numerically characterize the credibility of this gauge-dependent calculation
and find that the uncertainty due to gauge parameter dependence is under

709.2317 | Adjusted Viterbi training for hidden Markov models | To estimate the emission parameters in hidden Markov models one commonly uses
the EM algorithm or its variation. Our primary motivation, however, is the
Philips speech recognition system wherein the EM algorithm is replaced by the
Viterbi training algorithm. Viterbi training is faster and computationally less
involved than EM, but it is also biased and need not even be consistent. We
propose an alternative to the Viterbi training -- adjusted Viterbi training --
that has the same order of computational complexity as Viterbi training but
gives more accurate estimators. Elsewhere, we studied the adjusted Viterbi
training for a special case of mixtures, supporting the theory by simulations.
This paper proves the adjusted Viterbi training to be also possible for more
general hidden Markov models.

709.2321 | An inhomogeneous Josephson phase in thin-film and High-Tc
superconductors | In many cases inhomogeneities are known to exist near the metal (or
superconductor)-insulator transition, as follows from well-known domain-wall
arguments. If the conducting regions are large enough (i.e. when the T=0
superconducting gap is much larger than the single-electron level spacing), and
if they have superconducting correlations, it becomes energetically favorable
for the system to go into a Josephson-coupled zero-resistance state before
(i.e. at higher resistance than) becoming a "real" metal. We show that this is
plausible by a simple comparison of the relevant coupling constants. For small
grains in the above sense, the electronic grain structure is washed out by
delocalization and thus becomes irrelevant. When the proposed "Josephson state"
is quenched by a magnetic field, an insulating, rather then a metallic, state
should appear. This has been shown to be consistent with the existing data on
oxide materials as well as ultra-thin films. We discuss the Uemura correlations
versus the Homes law, and derive the former for the large-grain Josephson array
(inhomogenous superconductor) model. The small-grain case behaves like a dirty
homogenous metal. It should obey the Homes law provided that the system is in
the dirty supeconductivity limit. A speculation why that is typically the case
for d-wave superconductors is presented.

709.2322 | Exact enumeration of Hamiltonian circuits, walks, and chains in two and
three dimensions | We present an algorithm for enumerating exactly the number of Hamiltonian
chains on regular lattices in low dimensions. By definition, these are sets of
k disjoint paths whose union visits each lattice vertex exactly once. The
well-known Hamiltonian circuits and walks appear as the special cases k=0 and
k=1 respectively. In two dimensions, we enumerate chains on L x L square
lattices up to L=12, walks up to L=17, and circuits up to L=20. Some results
for three dimensions are also given. Using our data we extract several
quantities of physical interest.

709.2323 | Unbiased sampling of globular lattice proteins in three dimensions | We present a Monte Carlo method that allows efficient and unbiased sampling
of Hamiltonian walks on a cubic lattice. Such walks are self-avoiding and visit
each lattice site exactly once. They are often used as simple models of
globular proteins, upon adding suitable local interactions. Our algorithm can
easily be equipped with such interactions, but we study here mainly the
flexible homopolymer case where each conformation is generated with uniform
probability. We argue that the algorithm is ergodic and has dynamical exponent
z=0. We then use it to study polymers of size up to 64^3 = 262144 monomers.
Results are presented for the effective interaction between end points, and the
interaction with the boundaries of the system.

709.2324 | Construction of Fredholm representations and a modification of the
Higson-Roe corona | The Fredholm representation theory is well adapted to construction of
homotopy invariants of non simply connected manifolds on the base of
generalized Hirzebruch formula. Earlier a natural family of the Fredholm
representations was constructed that lead to a symmetric vector bundle on
completion of the fundamental group with a modification of the Higson-Roe
corona when the completion is a closed manifold. Here we will discuss a
homology version of symmetry in the case when completion with a modification of
the Higson-Roe corona is a manifold with boundary. The results were developed
during the visit of the first author in Ancona on March, 2007. The second

709.2327 | Spiral Growth and Step Edge Barriers | The growth of spiral mounds containing a screw dislocation is compared to the
growth of wedding cakes by two-dimensional nucleation. Using phase field
simulations and homoepitaxial growth experiments on the Pt(111) surface we show
that both structures attain the same characteristic large scale shape when a
significant step edge barrier suppresses interlayer transport. The higher
vertical growth rate observed for the spiral mounds on Pt(111) reflects the

exception, identified with persistent X-ray sources. The known bursters were
responsible for 215 of the localized events. One burst was detected from
AXJ1754.2-2754, the source previously unknown as a burster, and another burst -
from a new source. There was duality in determining its position - its name
could be either IGR J17364-2711 or IGR J17380-3749. Curiously enough, the 138
bursts were detected from one X-ray burster - GX 354-0.

709.2329 | Direct observation of high-speed plasma outflows produced by magnetic
reconnection in solar impulsive events | Spectroscopic observations of a solar limb flare recorded by SUMER on SOHO
reveal, for the first time, hot fast magnetic reconnection outflows in the
corona. As the reconnection site rises across the SUMER spectrometer slit,
significant blue- and red-shift signatures are observed in sequence in the Fe
XIX line, reflecting upflows and downflows of hot plasma jets, respectively.
With the projection effect corrected, the measured outflow speed is between
900-3500 km/s, consistent with theoretical predictions of the Alfvenic outflows
in magnetic reconnection region in solar impulsive events. Based on theoretic

709.2331 | Conjugate Points in Length Spaces | In this paper we extend the concept of a conjugate point in a Riemannian
manifold to complete length spaces (also known as geodesic spaces). In
particular, we introduce symmetric conjugate points and ultimate conjugate
points. We then generalize the long homotopy lemma of Klingenberg to this
setting as well as the injectivity radius estimate also due to Klingenberg
which was used to produce closed geodesics or conjugate points on Riemannian
manifolds. Our versions apply in this more general setting. We next focus on
${\rm CBA}(\kappa)$ spaces, proving Rauch-type comparison theorems. In
particular, much like the Riemannian setting, we prove an Alexander-Bishop
theorem stating that there are no ultimate conjugate points less than $\pi$
apart in a ${\rm CBA}(1)$ space. We also prove a relative Rauch comparison
theorem to precisely estimate the distance between nearby geodesics. We close
with applications and open problems.

709.2333 | Diffusion, super-diffusion and coalescence from single step | From the exact single step evolution equation of the two-point correlation
function of a particle distribution subjected to a stochastic displacement
field $\bu(\bx)$, we derive different dynamical regimes when $\bu(\bx)$ is
iterated to build a velocity field. First we show that spatially uncorrelated
fields $\bu(\bx)$ lead to both standard and anomalous diffusion equation. When
the field $\bu(\bx)$ is spatially correlated each particle performs a simple
free Brownian motion, but the trajectories of different particles result to be
mutually correlated. The two-point statistical properties of the field
$\bu(\bx)$ induce two-point spatial correlations in the particle distribution
satisfying a simple but non-trivial diffusion-like equation. These
displacement-displacement correlations lead the system to three possible
regimes: coalescence, simple clustering and a combination of the two. The
existence of these different regimes, in the one-dimensional system, is shown
through computer simulations and a simple theoretical argument.
