710.1653 | Superhumps and flickering in V1316 Cygni | We present analysis and results of a coordinated CCD photometry campaign to
observe the 2006 June superoutburst of the cataclysmic variable V1316 Cyg
involving 8 longitudinally-distributed observers. The outburst peaked at
magnitude 15.03 on June 10, declined at a rate of 0.14 mag/day, lasted 11 days
and had an amplitude above quiescence of 2.4 magnitudes. We detected common
superhumps for the first time, thereby confirming that V1316 Cyg is a member of
the UGSU class of dwarf novae. We observed a transition to late superhumps
two-thirds of the way through the outburst with an associated phase shift of
0.50 +/- 0.06 cycles. The mean common superhump period before this transition
was 0.07685 +/- 0.00003 d and the mean late superhump period following the
transition was 0.07654 +/- 0.00002 d. The common superhump period decreased at
a rate dP/dt = -5.1 +/- 1.7 x10^-5 /cycle. At the onset of late superhumps,
there was a transient shift in power from the superhump fundamental frequency
to its first harmonic and back again. We detected an orbital period of 0.0740
+/- 0.0002 d giving a fractional superhump period excess of 0.038 +/- 0.003 and
a mass ratio of 0.167 +/- 0.010. A scalegram analysis of the flickering
behaviour of V1316 Cyg found that the alpha and sigma parameters characterising
flickering changed significantly during the superoutburst. We also found
flickering to be at a relatively much lower level at the beginning of the
superoutburst and during two normal outbursts.

710.1654 | GOODS 850-5 -- A z>4 Galaxy Discovered in the Submillimeter? | We report an SMA interferometric identification of a bright submillimeter
source, GOODS 850-5. This source is one of the brightest 850 um sources in the
GOODS-N but is extremely faint at all other wavelengths. It is not detected in
the GOODS HST ACS images and only shows a weak 2 sigma signal at 1.4 GHz. It is
detected in the Spitzer IRAC bands and the MIPS 24 um band, however, with very
low fluxes. We present evidence in the radio, submillimeter, mid-IR, near-IR,
and optical that suggest GOODS 850-5 may be a z>4 galaxy.

710.1655 | Toward a precise determination of Tc with 2+1 flavors of quarks | We present a status report on a new high statistics study of the high
temperature transition in full QCD at zero chemical potential. Our simulations
use both improved asqtad and p4 staggered quarks on lattices with a temporal
extent N_t = 8 and light quark masses approximately one tenth the strange quark
mass. In this report we describe the setup of our calculations and present a
preliminary analysis of a variety of sources of systematic error and ambiguity
in the determination of the crossover temperature. We propose to present our
final analysis with double the current statistics. These calculations were

710.1656 | Heavy deformed nuclei in the shell model Monte Carlo method | We extend the shell model Monte Carlo approach to heavy deformed nuclei using
a new proton-neutron formalism. The low excitation energies of such nuclei
necessitate calculations at low temperatures for which a stabilization method
is implemented in the canonical ensemble. We apply the method to study a well
deformed rare-earth nucleus, 162Dy. The single-particle model space includes
the 50-82 shell plus 1f_{7/2} orbital for protons and the 82-126 shell plus
0h_{11/2}, 1g_{9/2} orbitals for neutrons. We show that the spherical shell
model reproduces well the rotational character of 162Dy within this model
space. We also calculate the level density of 162Dy and find it to be in
excellent agreement with the experimental level density, which we extract from
several experiments.

710.1657 | Manipulating Biopolymer Dynamics by Anisotropic Nanoconfinement | How the geometry of nano-sized confinement affects dynamics of biomaterials
is interesting yet poorly understood. An elucidation of structural details upon
nano-sized confinement may benefit manufacturing pharmaceuticals in biomaterial
sciences and medicine. The behavior of biopolymers in nano-sized confinement is
investigated using coarse-grained models and molecular simulations.
Particularly, we address the effects of shapes of a confinement on protein
folding dynamics by measuring folding rates and dissecting structural
properties of the transition states in nano-sized spheres and ellipsoids. We
find that when the form of a confinement resembles the geometrical properties
of the transition states, the rates of folding kinetics are most enhanced. This
knowledge of shape selectivity in identifying optimal conditions for reactions
will have a broad impact in nanotechnology and pharmaceutical sciences.
| physics.bio-ph | how the geometry of nanosized confinement affects dynamics of biomaterials is interesting yet poorly understood an elucidation of structural details upon nanosized confinement may benefit manufacturing pharmaceuticals in biomaterial sciences and medicine the behavior of biopolymers in nanosized confinement is investigated using coarsegrained models and molecular simulations particularly we address the effects of shapes of a confinement on protein folding dynamics by measuring folding rates and dissecting structural properties of the transition states in nanosized spheres and ellipsoids we find that when the form of a confinement resembles the geometrical properties of the transition states the rates of folding kinetics are most enhanced this knowledge of shape selectivity in identifying optimal conditions for reactions will have a broad impact in nanotechnology and pharmaceutical sciences | [['how', 'the', 'geometry', 'of', 'nanosized', 'confinement', 'affects', 'dynamics', 'of', 'biomaterials', 'is', 'interesting', 'yet', 'poorly', 'understood', 'an', 'elucidation', 'of', 'structural', 'details', 'upon', 'nanosized', 'confinement', 'may', 'benefit', 'manufacturing', 'pharmaceuticals', 'in', 'biomaterial', 'sciences', 'and', 'medicine', 'the', 'behavior', 'of', 'biopolymers', 'in', 'nanosized', 'confinement', 'is', 'investigated', 'using', 'coarsegrained', 'models', 'and', 'molecular', 'simulations', 'particularly', 'we', 'address', 'the', 'effects', 'of', 'shapes', 'of', 'a', 'confinement', 'on', 'protein', 'folding', 'dynamics', 'by', 'measuring', 'folding', 'rates', 'and', 'dissecting', 'structural', 'properties', 'of', 'the', 'transition', 'states', 'in', 'nanosized', 'spheres', 'and', 'ellipsoids', 'we', 'find', 'that', 'when', 'the', 'form', 'of', 'a', 'confinement', 'resembles', 'the', 'geometrical', 'properties', 'of', 'the', 'transition', 'states', 'the', 'rates', 'of', 'folding', 'kinetics', 'are', 'most', 'enhanced', 'this', 'knowledge', 'of', 'shape', 'selectivity', 'in', 'identifying', 'optimal', 'conditions', 'for', 'reactions', 'will', 'have', 'a', 'broad', 'impact', 'in', 'nanotechnology', 'and', 'pharmaceutical', 'sciences']] | [-0.10180541508335379, 0.18814450138609484, -0.07986798716498719, 0.05912931849748167, -0.027088608595565142, -0.09101552024038674, 0.01321809250305617, 0.41519243354278224, -0.2811773204893172, -0.29354762306977666, 0.03874857248944951, -0.2254503305021283, -0.2280448207541579, 0.15622581325935184, -0.06160324161511756, 0.029059227612320212, 0.02802700017421176, -0.057749317928908334, -0.024519372369057588, -0.13868965755306906, 0.24226215167812282, 0.08887750009870937, 0.31890376477367094, 0.15366309835395264, 0.036938361057470885, -0.020453902742555066, 0.0583305410353557, -0.003918810334477213, -0.21839339197304658, 0.1531522135961906, 0.26498292406754886, 0.0732436571457994, 0.2523899809832895, -0.4534477408254339, -0.2749014247249673, 0.028223830496802205, 0.16438494924260605, 0.12435410598353032, -0.10162103093217968, -0.22624323056304768, 0.008378284795570278, -0.0827089951546382, -0.12958972049771897, -0.10926714641485183, 0.0446437340560219, 0.07323715429408602, -0.17726775769880343, 0.0962115767291717, 0.06215026620174608, 0.12272458709025334, -0.09752062290546394, -0.11174224579196063, -0.04216141414438044, 0.16547674107418825, 0.01709069522292984, -0.07226034895622081, 0.288826742930518, -0.2309077431864646, -0.10762763331313768, 0.4511293819204213, 0.038010561821847075, -0.19765602791261289, 0.2171406023084156, -0.1519579602848558, -0.16829113261924394, 0.15429253041774274, 0.1824251088321269, 0.12003908311383002, -0.18082041313907887, 0.07187455022217511, 0.05568238523142833, 0.1590436105541284, 0.09631211968934944, 0.03865518236172295, 0.23007225070238835, 0.2672918534203012, -0.04098504230252377, 0.16097007739928462, -0.056620350263396936, -0.14600030235165068, -0.20474792939550693, -0.15221127062743048, -0.1765582169811692, 0.05324162099502921, -0.07870760499328401, -0.1869578974386264, 0.3680012263151096, 0.08854119714458412, 0.18316196513572527, -0.07407001408019794, 0.20576313093319656, -0.04025818381999289, 0.054125525673190435, -0.056820020980892644, 0.2534567672503932, 0.15437795598653234, 0.10803639162857566, -0.2632137828632333, 0.14670263510385168, -0.014870411615007587] |

710.1661 | General Theory of the Quantum Kicked Rotator. I | This is the first of a series of two papers. We discuss some basic problems
of the quantum kicked rotator (QKR) and review some important results in the
literature. We point out the flaws in the inverse Cayley transform method to
prove dynamic localization. When $\tau/2\pi$, where $\tau$ is the kick period,
is very close to a rational number, the localization length is larger than the
typical localization length. We analytically prove anomalous localization and
confirm it by numerical calculations. We point out open problems that need
further work.

710.1663 | Modeling Phase-resolved Observations of the Surfaces of Magnetic Neutron
Stars | Recent observations by XMM-Newton detected rotational pulsations in the total
brightness and spectrum of several neutron stars. To properly interpret the
data, accurate modeling of neutron star emission is necessary. Detailed
analysis of the shape and strength of the rotational variations allows a
measurement of the surface composition and magnetic field, as well as
constrains the nuclear equation of state. We discuss our models of the spectra
and light curves of two of the most observed neutron stars, RX J1856.5-3754 and

710.1666 | The role of Stellar Feedback in the formation of galactic disks and
bulges in a LCDM Universe | Although supernova explosions and stellar winds happens at scales bellow 100
pc, they affect the interstellar medium(ISM) and galaxy formation. We use
cosmological N-body+Hydrodynamics simulations of galaxy formation, as well as
simulations of the ISM to study the effect of stellar feedback on galactic
scales. Stellar feedback maintains gas with temperatures above a million
degrees. This gas fills bubbles, super-bubbles and chimneys. Our model of
feedback, in which 10%-30% of the feedback energy is coming from runaway stars,
reproduces this hot gas only if the resolution is better than 50 pc. This is 10
times better than the typical resolution in cosmological simulations of galaxy
formation. Only with this resolution, the effect of stellar feedback in galaxy
formation is resolved without any assumption about sub-resolution physics.

710.1668 | Direct Detection of Non-Chiral Dark Matter | Direct detection experiments rule out fermion dark matter that is a chiral
representation of the electroweak gauge group. Non-chiral real, complex and
singlet representations, however, provide viable fermion dark matter
candidates. Although any one of these candidates will be virtually impossible
to detect at the LHC, it is shown that they may be detected at future planned
direct detection experiments. For the real case, an irreducible radiative
coupling to quarks may allow a detection. The complex case in general has an
experimentally ruled out tree-level coupling to quarks via Z-boson exchange.
However, in the case of two SU(2)_L doublets, a higher dimensional coupling to
the Higgs can suppress this coupling, and a remaining irreducible radiative
coupling may allow a detection. Singlet dark matter could be detected through a
coupling to quarks via Higgs exchange. Since all non-chiral dark matter can
have a coupling to the Higgs, at least some of its mass can be obtained from

710.167 | Fermion Production in Strong Magnetic Field and its Astrophysical
Implications | We calculate the effective potential of a strong magnetic field induced by
fermions with anomalous magnetic moments which couple to the electromagnetic
field in the form of the Pauli interaction. For a uniform magnetic field, we
find the explicit form of the effective potential. It is found that the
non-vanishing imaginary part develops for a magnetic field stronger than a
critical field and has a quartic form which is quite different from the
exponential form of the Schwinger process. We also consider a linear magnetic
field configuration as an example of inhomogeneous magnetic fields. We find
that the imaginary part of the effective potential is nonzero even below the
critical field and shows an exponentially decreasing behavior with respect to
the inverse of the magnetic field gradient, which is the non-perturbative
characteristics analogous to the Schwinger process. These results imply the
instability of the strong magnetic field to produce fermion pairs as a purely
magnetic effect. The possible applications to the astrophysical phenomena with

710.1672 | A Kaluza-Klein Model with Spontaneous Symmetry Breaking: Light-Particle
Effective Action and its Compactification Scale Dependence | We investigate decoupling of heavy Kaluza-Klein modes in an Abelian Higgs
model with space-time topologies $\mathbb{R}^{3,1} \times S^{1}$ and
$\mathbb{R}^{3,1} \times S^{1}/\mathbb{Z}_{2}$. After integrating out heavy KK
modes we find the effective action for the zero mode fields. We find that in
the $\mathbb{R}^{3,1} \times S^{1}$ topology the heavy modes do not decouple in
the effective action, due to the zero mode of the 5-th component of the 5-d
gauge field $A_{5}$. Because $A_{5}$ is a scalar under 4-d Lorentz
transformations, there is no gauge symmetry protecting it from getting mass and
$A_{5}^{4}$ interaction terms after loop corrections. In addition, after
symmetry breaking, we find new divergences in the $A_{5}$ mass that did not
appear in the symmetric phase. The new divergences are traced back to the
gauge-goldstone mixing that occurs after symmetry breaking. The relevance of
these new divergences to Symanzik's theorem is discussed. In order to get a
more sensible theory we investigate the $S^{1}/\mathbb{Z}_{2}$
compactification. With this kind of compact topology, the $A_{5}$ zero mode
disappears. With no $A_{5}$, there are no new divergences and the heavy modes
decouple. We also discuss the dependence of the couplings and masses on the
compactification scale. We derive a set of RG-like equations for the running of
the effective couplings with respect to the compactification scale. It is found
that magnitudes of both couplings decrease as the scale $M$ increases. The
effective masses are also shown to decrease with increasing compactification
scale. All of this opens up the possibility of placing constraints on the size
of extra dimensions.

extraordinary optical transmission through subwavelength holes in optically
thick metal plate. It is found that the phase of incident light can be

interference of SPPs by modulating the relative phase between two incident
beams. Using a slightly displaced Mach-Zehnder interferometer, we also observe
a SPPs interference pattern composed of bright and dark stripes.

710.1675 | Is the cosmological "constant" a nonlocal quantum residue of
discreteness of the causal set type? | The evidence for an accelerating Hubble expansion appears to have confirmed
the heuristic prediction, from causal set theory, of a fluctuating and
``ever-present'' cosmological term in the Einstein equations. A more concrete
phenomenological model incorporating this prediction has been devised and

Mutations | In this work, charge transport (CT) properties of the p53 gene are
numerically studied by the transfer matrix method, and using either single or
double strand effective tight-binding models. A statistical analysis of the
consequences of known p53 point mutations on CT features is performed. It is
found that in contrast to other kind of mutation defects, cancerous mutations
result in much weaker changes of CT efficiency. Given the envisioned role
played by CT in the DNA-repairing mechanism, our theoretical results suggest an
underlying physical explanation at the origin of carcinogenesis.

710.1677 | A Search for 6.7 GHz Methanol Masers in M33 | We report the negative results from a search for 6.7 GHz methanol masers in
the nearby spiral galaxy M33. We observed 14 GMCs in the central 4 kpc of the
Galaxy, and found 3 sigma upper limits to the flux density of ~9 mJy in
spectral channels having a velocity width of 0.069 km/s. By velocity shifting
and combining the spectra from the positions observed, we obtain an effective
3sigma upper limit on the average emission of ~1mJy in a 0.25 km/s channel.
These limits lie significantly below what we would expect based on our
estimates of the methanol maser luminosity function in the Milky Way. The most
likely explanation for the absence of detectable methanol masers appears to be
the metallicity of M33, which is modestly less than that of the Milky Way.

710.1678 | Resolving the Formation of Protogalaxies. II. Central Gravitational
Collapse | Numerous cosmological hydrodynamic studies have addressed the formation of
galaxies. Here we choose to study the first stages of galaxy formation,
including non-equilibrium atomic primordial gas cooling, gravity and
hydrodynamics. Using initial conditions appropriate for the concordance
cosmological model of structure formation, we perform two adaptive mesh
refinement simulations of ~10^8 M_sun galaxies at high redshift. The
calculations resolve the Jeans length at all times with more than 16 cells and
capture over 14 orders of magnitude in length scales. In both cases, the dense,
10^5 solar mass, one parsec central regions are found to contract rapidly and
have turbulent Mach numbers up to 4. Despite the ever decreasing Jeans length
of the isothermal gas, we only find one site of fragmentation during the
collapse. However, rotational secular bar instabilities transport angular
momentum outwards in the central parsec as the gas continues to collapse and
lead to multiple nested unstable fragments with decreasing masses down to
sub-Jupiter mass scales. Although these numerical experiments neglect star
formation and feedback, they clearly highlight the physics of turbulence in
gravitationally collapsing gas. The angular momentum segregation seen in our
calculations plays an important role in theories that form supermassive black
holes from gaseous collapse.

710.1681 | Tree FCNC and non-unitarity of CKM matrix | We discuss possible signatures of the tree level FCNC, which results from the
non-unitarity of CKM matrix. We first define the unitaity step-by-step, and
possible test of the non-unitaity through the 4-value-KM parametrization. We,
then, show how the phase angle of the unitary triangle would change in case of
the vector-like down quark model. As another example of tree FCNC, we

710.1682 | Constraining the parameters of binary systems through time-dependent
light deflection | A theory is derived relating the configuration of the cores of active
galaxies, specifically candidates for presumed super-massive black hole
binaries (SMBHBs), to time-dependent changes in images of those galaxies. Three
deflection quantities, resulting from the monopole term, mass quadrupole term,
and spin dipole term of the core, are examined. The resulting observational
technique is applied to the galaxy 3C66B. This technique is found to under
idealized circumstances surpass the technique proposed by Jenet et al. in
accuracy for constraining the mass of SMBHB candidates, but is exceeded in
accuracy and precision by Jenet's technique under currently-understood likely
conditions. The technique can also under favorable circumstances produce
results measurable by currently-available astronomical interferometry such as
very-long baseline-interferometry (VLBI).

710.1683 | Biases in the Gravitational Lens Population Induced by Halo and Galaxy
Triaxiality | The lensing cross section of triaxial halos depends on the relative
orientation between a halo's principal axes and its line of sight.
Consequently, a lensing subsample of randomly oriented halos is not, in
general,randomly oriented. Using an isothermal mass model for the lensing
galaxies and their host halos, we show that the lensing subsample of halos that
produces doubles is preferentially aligned along the lines of sight, whereas
halos that produce quads tend to be projected along their middle axes. These
preferred orientations result in different projected ellipticity distributions
for quad, doubles, and random galaxies. We show that ~300 lens systems must be
discovered to detect this effect at the 95% confidence level. We also
investigate the importance of halo shape for predicting the quad-to-double
ratio and find that the latter depends quite sensitively on the distribution of
the short-to-long axis ratio, but is otherwise nearly independent of halo
shape. Finally, we estimate the impact of the preferred orientation of lensing
galaxies on their projected substructure mass fraction, and find that the
observed alignment between the substructure distribution and the mass
distribution of halos result in a negligible bias.

710.1684 | Comments on gluon 6-point scattering amplitudes in N=4 SYM at strong
coupling | We use the AdS/CFT prescription of Alday and Maldacena \cite{am} to analyze
gluon 6-point scattering amplitudes at strong coupling in ${\cal N}=4$ SYM. By
cutting and gluing we obtain AdS 6-point amplitudes that contain extra boundary
conditions and come close to matching the field theory results. We interpret
them as parts of the field theory amplitudes, containing only certain diagrams.
We also analyze the collinear limits of 6- and 5-point amplitudes and discuss
the results.

710.1686 | Electronic functionalization of the surface of organic semiconductors
with self-assembled monolayers | Molecular self-assembly has been extensively used for surface modification of
metals and oxides for a variety of applications, including molecular and
organic electronics. One of the goals of this research is to learn how the
electronic properties of these surfaces can be modified by self-assembled
monolayers (SAM). Here, we demonstrate a new type of molecular self-assembly:
the growth of organosilane SAMs at the surface of organic semiconductors, which
results in a dramatic increase of the surface conductivity of organic
materials. For organosilane molecules with a large dipole moment, SAM-induced
surface conductivity of organic molecular crystals approaches 10^-5 S per
square, which is comparable to the highest conductivity realized in organic
field-effect transistors (OFETs) at ultra-high densities of charge carriers.
SAM-functionalized organic surfaces are fully accessible to the environment
which makes them very attractive for sensing applications. We have observed
that the interaction of vapors of polar molecules with SAM-functionalized
organic semiconductors results in a fast and reversible change of the
conductivity, proportional to the pressure of an analyte vapor.

710.1687 | Statistically interacting quasiparticles in Ising chains | The exclusion statistics of two complementary sets of quasiparticles,
generated from opposite ends of the spectrum, are identified for Ising chains
with spin s=1/2,1. In the s=1/2 case the two sets are antiferromagnetic domain
walls (solitons) and ferromagnetic domains (strings). In the s=1 case they are
soliton pairs and nested strings, respectively. The Ising model is equivalent
to a system of two species of solitons for s=1/2 and to a system of six species
of soliton pairs for s=1. Solitons exist on single bonds but soliton pairs may
be spread across many bonds. The thermodynamics of a system of domains spanning
up to $M$ lattice sites is amenable to exact analysis and shown to become
equivalent, in the limit M -> infinity, to the thermodynamics of the s=1/2
Ising chain. A relation is presented between the solitons in the Ising limit
and the spinons in the XX limit of the s=1/2 XXZ chain.

710.1688 | Adaptive estimation of linear functionals by model selection | We propose an estimation procedure for linear functionals based on Gaussian
model selection techniques. We show that the procedure is adaptive, and we give
a non asymptotic oracle inequality for the risk of the selected estimator with
respect to the $\mathbb{L}_p$ loss. An application to the problem of estimating
a signal or its $r^{th}$ derivative at a given point is developed and minimax
rates are proved to hold uniformly over Besov balls. We also apply our non
asymptotic oracle inequality to the estimation of the mean of the signal on an
interval with length depending on the noise level. Simulations are included to
illustrate the performances of the procedure for the estimation of a function
at a given point. Our method provides a pointwise adaptive estimator.

710.169 | Inference in nonparametric current status models with covariates | In interval censored models with current status observations, the variables
are indicators of the presence of individuals on observation intervals and
covariates. When several individuals share the same observation interval, a
simple procedure provides new estimators for the distribution of the
observation times and their intensity, in a closed form. They are
$n^{1/2}$-consistent for piece-wise constant covariates. Estimators of the
sample-sizes are deduced and asymptotic $\chi^2$ tests for independence of the
observations on consecutive intervals and for independence between consecutive
classes for the observed individuals are proposed.

710.1691 | UCDs - more massive than allowed? | Dynamical mass estimates of ultra-compact dwarfs galaxies and massive
globular clusters in the Fornax and Virgo clusters and around the giant
elliptical Cen A have revealed some surprising results: 1) above about 10^6
M_sun the mass-to-light (M/L) ratio increases with the objects' mass; 2) some
UCDs/massive GCs show high M/L values (4 to 6) that are not compatible with
standard stellar population models; and 3) in the luminosity-velocity
dispersion diagram, UCDs deviate from the well defined relation of `normal'
GCs, being more in line with the Faber-Jackson relation of early-type galaxies.
In this contribution, we present the observational evidences for high
mass-to-light ratios of UCDs and discuss possible explanations for them.

710.1692 | Rates of asymptotic regularity for Halpern iterations of nonexpansive
mappings | In this paper we obtain new effective results on the Halpern iterations of
nonexpansive mappings using methods from mathematical logic or, more
specifically, proof-theoretic techniques. We give effective rates of asymptotic
regularity for the Halpern iterations of nonexpansive self-mappings of nonempty
convex sets in normed spaces. The paper presents another case study in the

710.1694 | An efficient modulation scheme for dual beam polarimetry | An eight stage balanced modulation scheme for dual beam polarimetry is
presented in this paper. The four Stokes parameters are weighted equally in all
the eight stages of modulation resulting in total polarimetric efficiency of
unity. The gain table error inherent in dual beam system is reduced by using
the well known beam swapping technique. The wavelength dependent polarimetric
efficiencies of Stokes parameters due to the chromatic nature of the waveplates
are presented. The proposed modulation scheme produces better Stokes $Q$ and
$V$ efficiencies for wavelengths larger than the design wavelength whereas
Stokes $U$ has better efficiency in the shorter wavelength region. Calibration
of the polarimeter installed as a backend instrument of the Kodaikanal Tower
Telescope is presented. It is found through computer simulation that a 14% sky
transparency variation during calibration of the polarimeter can introduce
$\approx 1.8%$ uncertainty in the determination of its response matrix.

710.1695 | On the large-scale angular distribution of short-Gamma ray bursts | We investigate the large-scale angular distribution of the short-Gamma ray
bursts (SGRBs) from BATSE experiment, using a new coordinates-free method. The
analyses performed take into account the angular correlations induced by the
non-uniform sky exposure during the experiment, and the uncertainty in the
measured angular coordinates. Comparising the large-scale angular correlations
from the data with those expected from simulations using the exposure function
we find similar features. Additionally, confronting the large-angle
correlations computed from the data with those obtained from simulated maps
produced under the assumption of statistical isotropy we found that they are
incompatible at 95% confidence level. However, such differences are restricted
to the angular scales 36o - 45o, which are likely to be due to the non-uniform
sky exposure. This result strongly suggests that the set of SGRBs from BATSE
are intrinsically isotropic. Moreover, we also investigated a possible
large-angle correlation of these data with the supergalactic plane. No evidence
for such large-scale anisotropy was found.

710.1696 | pi-pi and pi-K scatterings in three-flavour resummed chiral perturbation
theory | The (light but not-so-light) strange quark may play a special role in the
low-energy dynamics of QCD. The presence of strange quark pairs in the sea may
have a significant impact of the pattern of chiral symmetry breaking : in
particular large differences can occur between the chiral limits of two and
three massless flavours (i.e., whether m_s is kept at its physical value or
sent to zero). This may induce problems of convergence in three-flavour chiral
expansions. To cope with such difficulties, we introduce a new framework,
called Resummed Chiral Perturbation Theory. We exploit it to analyse pi-pi and
pi-K scatterings and match them with dispersive results in a frequentist
framework. Constraints on three-flavour chiral order parameters are derived.

710.1697 | Lifetime of OH masers at the tip of the asymptotic giant branch | Context: A large fraction of otherwise similar asymptotic giant branch stars
(AGB) do not show OH maser emission. As shown recently, a restricted lifetime
may give a natural explanation as to why only part of any sample emits maser
emission at a given epoch.
Aims: We wish to probe the lifetime of 1612 MHz OH masers in circumstellar
shells of AGB stars.
Methods: We reobserved a sample of OH/IR stars discovered more than 28 years
ago to determine the number of stars that may have since lost their masers.
Results: We redetected all 114 OH masers. The minimum lifetime inferred is
2800 years (1 sigma). This maser lifetime applies to AGB stars with strong mass
loss leading to very red infrared colors. The velocities and mean flux density
levels have not changed since their discovery. As the minimum lifetime is of
the same order as the wind crossing time, strong variations in the mass-loss
process affecting the excitation conditions on timescales of ~3000 years or

710.1698 | Neutron scattering study of magnetic ordering and excitations in the
ternary rare-earth diborocarbide Ce^{11}B_2C_2 | Neutron scattering experiments have been performed on the ternary rare-earth
diborocarbide Ce$^{11}$B$_2$C$_2$. The powder diffraction experiment confirms
formation of a long-range magnetic order at $T_{\rm N} = 7.3$ K, where a
sinusoidally modulated structure is realized with the modulation vector ${\bm
q} = [0.167(3), 0.167(3), 0.114(3)]$. Inelastic excitation spectra in the
paramagnetic phase comprise significantly broad quasielastic and inelastic
peaks centered at $\hbar \omega \approx 0, 8$ and 65 meV.
Crystalline-electric-field (CEF) analysis satisfactorily reproduces the
observed spectra, confirming their CEF origin. The broadness of the
quasielastic peak indicates strong spin fluctuations due to coupling between
localized $4f$ spins and conduction electrons in the paramagnetic phase. A
prominent feature is suppression of the quasielastic fluctuations, and
concomitant growth of a sharp inelastic peak in a low energy region below
$T_{\rm N}$. This suggests dissociation of the conduction and localized $4f$
electrons on ordering, and contrasts the presently observed incommensurate
phase with spin-density-wave order frequently seen in heavy fermion compounds,
such as Ce(Ru$_{1-x}$La$_x$)$_2$Si$_2$.

710.1699 | Finitely generated lattice-ordered groups with soluble word problem | William W. Boone and Graham Higman proved that a finitely generated group has
soluble word problem if and only if it can be embedded in a simple group that
can be embedded in a finitely presented group. We prove the exact analogue for
lattice-ordered groups: Theorem: A finitely generated lattice-ordered group has
soluble word problem if and only if it can be embedded in an simple
lattice-ordered group that can be embedded in a finitely presented

710.17 | The Spatially Closed Universe | The general world model for homogeneous and isotropic universe has been
roposed. For this purpose, we introduce a global and fiducial system of
reference (world reference frame) constructed on a 5-dimensional space-time
that is embedding the universe, and define the line element as the separation
between two neighboring events that are distinct in space and time, as viewed
in the world reference frame. The effect of cosmic expansion on the measurement
of physical distance has been correctly included in the new metric, which
differs from the Friedmann-Robertson-Walker metric where the spatial separation
is measured for events on the hypersurface at a constant time while the
temporal separation is measured for events at different time epochs. The
Einstein's field equations with the new metric imply that closed, flat, and
open universes are filled with positive, zero, and negative energy,
respectively. We have demonstrated that the flat universe is empty and
stationary, equivalent to the Minkowski space-time, and that the universe with
positive energy density is always spatially closed and finite. In the closed
universe, the proper time of a comoving observer does not elapse uniformly as
judged in the world reference frame, in which both cosmic expansion and
time-varying light speeds cannot exceed the limiting speed of the special
relativity. We have also reconstructed cosmic evolution histories of the closed
world models that are consistent with recent astronomical observations, and
derived useful formulas such as energy-momentum relation of particles,
redshift, total energy in the universe, cosmic distance and time scales, and so
forth. It has also been shown that the inflation with positive acceleration at
the earliest epoch is improbable.

710.1702 | Formation of solitons in atomic Bose-Einstein condensates by dark-state
adiabatic passage | We propose a new method of creating solitons in elongated Bose-Einstein
Condensates (BECs) by sweeping three laser beams through the BEC. If one of the
beams is in the first order (TEM10) Hermite-Gaussian mode, its amplitude has a
transversal phase slip which can be transferred to the atoms creating a
soliton. Using this method it is possible to circumvent the restriction set by
the diffraction limit inherent to conventional methods such as phase
imprinting. The method allows one to create multicomponent (vector) solitons of
the dark-bright form as well as the dark-dark combination. In addition it is
possible to create in a controllable way two or more dark solitons with very
small velocity and close to each other for studying their collisional
properties.

710.1704 | A giant controllable gap in the optical spectrum of a semiconductor
laser subject to intense feedback with rotated polarization | A semiconductor laser subject to delayed optical feedback is investigated in
the limit of extremely intense feedback power. In a range of feedback
polarization rotation angles the emission spectra of the laser reveal a giant
gap with width of more than a terahertz. The position of the gap and its width
are shown to be regulated by means of feedback polarization rotation angle. We

710.1705 | Dimensionality and morphology of particle and bubble clusters in
turbulent flow | We conduct numerical experiments to investigate the spatial clustering of
particles and bubbles in simulations of homogeneous and isotropic turbulence.
Varying the Stokes parameter and the densities, striking differences in the
clustering of the particles can be observed. To quantify these visual findings
we use the Kaplan--Yorke dimension. This local scaling analysis shows a
dimension of approximately 1.4 for the light bubble distribution, whereas the
distribution of very heavy particles shows a dimension of approximately 2.4.
However, clearly separate parameter combinations yield the same dimensions. To
overcome this degeneracy and to further develop the understanding of
clustering, we perform a morphological (geometrical and topological) analysis
of the particle distribution. For such an analysis, Minkowski functionals have
been successfully employed in cosmology, in order to quantify the global
geometry and topology of the large-scale distribution of galaxies. In the
context of dispersed multiphase flow, these Minkowski functionals -- being
morphological order parameters -- allow us to discern the filamentary structure
of the light particle distribution from the wall-like distribution of heavy
particles around empty interconnected tunnels.

710.1706 | Relativistic calculations of the lifetimes and hyperfine structure
constants in $^{67}$Zn$^{+}$ | This work presents accurate {\it ab initio} determination of the magnetic
dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the
ground and a few low-lying excited states in $^{67}$Zn$^{+}$, which is one of
the interesting systems in fundamental physics. The coupled-cluster (CC) theory
within the relativistic framework has been used here in this calculations. Long
standing demands for a relativistic and highly correlated calculations like CC
can be able to resolve the disagreements among the lifetime estimations
reported previously for a few low-lying states of Zn$^{+}$. The role of

710.1707 | M-theory branes and their interactions | In recent years there has been some progress in understanding how one might
model the interactions of branes in M-theory despite not having a fundamental
perturbative description. The goal of this review is to describe different
approaches to M-theory branes and their interactions. This includes: a review
of M-theory branes themselves and their properties; brane interactions; the
self-dual string and its properties; the role of anomalies in learning about
brane systems; the recent work of Basu and Harvey with subsequent developments;
and how these complimentary approaches might fit together.

710.1709 | Transport in Magnetic Nanoparticles Super-Lattices : Coulomb Blockade,
Hysteresis and Magnetic Field Induced Switching | We report on magnetotransport measurements on millimetric super-lattices of
Co-Fe nanoparticles surrounded by an organic layer. At low temperature, the
transition between the Coulomb blockade and the conductive regime becomes
abrupt and hysteretic. The transition between both regime can be induced by a
magnetic field, leading to a novel mechanism of magnetoresistance. Between 1.8
and 10 K, high-field magnetoresistance due to magnetic disorder at the surface

710.1712 | Exact results for quench dynamics and defect production in a
two-dimensional model | We show that for a d-dimensional model in which a quench with a rate
\tau^{-1} takes the system across a d-m dimensional critical surface, the
defect density scales as n \sim 1/\tau^{m\nu/(z\nu +1)}, where \nu and z are
the correlation length and dynamical critical exponents characterizing the
critical surface. We explicitly demonstrate that the Kitaev model provides an
example of such a scaling with d=2 and m=\nu=z=1. We also provide the first
example of an exact calculation of some multispin correlation functions for a

deconfinement and a chiral phase transition take place at different
temperatures. In this work, we present a study of the deconfinement transition
in the dual superconductor picture based on the evaluation of an operator which
carries magnetic charge. The expectation value of this operator signals
monopole condensation and is an order parameter for deconfinement as in the
case of fermions in the fundamental representation. We find a sharp first order
deconfinement transition. We also study the effects of the chiral transition on
the monopole order parameter and find them negligible.

Dor | AA Dor is an eclipsing, close, post common-envelope binary (PCEB). We present
a detailed spectral analysis of its sdOB primary star based on observations
obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE). Due to a
strong contamination by interstellar absorption, we had to model both, the
stellar spectrum as well as the interstellar line absorption in order to

710.1718 | Measuring the accretion rate and kinetic luminosity functions of
supermassive black holes | We derive accretion rate functions (ARFs) and kinetic luminosity functions
(KLF) for jet-launching supermassive black holes. The accretion rate as well as
the kinetic power of an active galaxy is estimated from the radio emission of
the jet. For compact low-power jets, we use the core radio emission while the
jet power of high-power radio-loud quasars is estimated using the extended
low-frequency emission to avoid beaming effects. We find that at low
luminosities the ARF derived from the radio emission is in agreement with the
measured bolometric luminosity function (BLF) of AGN, i.e., all low-luminosity
AGN launch strong jets. We present a simple model, inspired by the analogy
between X-ray binaries and AGN, that can reproduce both the measured ARF of
jet-emitting sources as well as the BLF. The model suggests that the break in
power law slope of the BLF is due to the inefficient accretion of strongly
sub-Eddington sources. As our accretion measure is based on the jet power it
also allows us to calculate the KLF and therefore the total kinetic power
injected by jets into the ambient medium. We compare this with the kinetic
power output from SNRs and XRBs, and determine its cosmological evolution.

advantage over any classical team. The quantum team has a clear advantage in
games in which the players of each team are separated in space and the quantum

710.1724 | Optimal Covariant Measurement of Momentum on a Half Line in Quantum
Mechanics | We cannot perform the projective measurement of a momentum on a half line
since it is not an observable. Nevertheless, we would like to obtain some
physical information of the momentum on a half line. We define an optimality
for measurement as minimizing the variance between an inferred outcome of the
measured system before a measuring process and a measurement outcome of the
probe system after the measuring process, restricting our attention to the
covariant measurement studied by Holevo. Extending the domain of the momentum
operator on a half line by introducing a two dimensional Hilbert space to be
tensored, we make it self-adjoint and explicitly construct a model Hamiltonian
for the measured and probe systems. By taking the partial trace over the newly
introduced Hilbert space, the optimal covariant positive operator valued
measure (POVM) of a momentum on a half line is reproduced. We physically

710.1725 | Pseudoscalar Flavor-Singlet Physics with Staggered Fermions | Accurately calculating the mass of flavor-singlet meson states from numerical
lattice simulations is an important milestone for lattice QCD. Careful
measurement of the full pseudoscalar flavor-singlet propagator is also a
crucial step in understanding the dynamics of the fermion sea on the lattice,
in particular for potentially non-trivial formulations such as with 2+1-flavor
staggered fermions. We briefly describe details of a dynamical QCD calculation
using improved staggered fermions, with 30,000 trajectories, that was run for
our studies of flavour singlet mesons.

710.1729 | The Grounds For Time Dependent Market Potentials From Dealers' Dynamics | We apply the potential force estimation method to artificial time series of
market price produced by a deterministic dealer model. We find that dealers'
feedback of linear prediction of market price based on the latest mean price
changes plays the central role in the market's potential force. When markets
are dominated by dealers with positive feedback the resulting potential force
is repulsive, while the effect of negative feedback enhances the attractive
potential force.

710.173 | Building Blue Stragglers with Stellar Collisions | The evolution of stellar collision products in cluster simulations has
usually been modelled using simplified prescriptions. Such prescriptions either
replace the collision product with an (evolved) main sequence star, or assume
that the collision product was completely mixed during the collision.
It is known from hydrodynamical simulations of stellar collisions that
collision products are not completely mixed, however. We have calculated the
evolution of stellar collision products and find that they are brighter than

710.1731 | A near-infrared interferometric survey of debris disk stars. I. Probing
the hot dust content around epsilon Eridani and tau Ceti with CHARA/FLUOR | We probed the first 3AU around tau Ceti and epsilon Eridani with the CHARA
array (Mt Wilson, USA) in order to gauge the 2micron excess flux emanating from
possible hot dust grains in the debris disks and to also resolve the stellar
photospheres. High precision visibility amplitude measurements were performed
with the FLUOR single mode fiber instrument and telescope pairs on baselines
ranging from 22 to 241m of projected length. The short baseline observations
allow us to disentangle the contribution of an extended structure from the
photospheric emission, while the long baselines constrain the stellar diameter.
We have detected a resolved emission around tau Cet, corresponding to a
spatially integrated, fractional excess flux of 0.98 +/- 0.21 x 10^{-2} with
respect to the photospheric flux in the K'-band. Around eps Eri, our
measurements can exclude a fractional excess of greater than 0.6x10^{-2}
(3sigma). We interpret the photometric excess around tau Cet as a possible
signature of hot grains in the inner debris disk and demonstrate that a faint,
physical or background, companion can be safely excluded. In addition, we
measured both stellar angular diameters with an unprecedented accuracy:
Theta_LD(tau Cet)= 2.015 +/- 0.011 mas and Theta_LD(eps Eri)=2.126 +/- 0.014
mas.

710.1732 | On the structure of the constraint algebra for systems whose gauge
transformations depend on higher order time derivatives of the gauge
parameters | The dynamical systems invariant under gauge transformations with higher order
time derivatives of the gauge parameter are considered from the Hamiltonian
point of view. We investigate the consequences of the basic requirements that
the constraints on the one hand and the Hamiltonian and constraints on the

710.1734 | When Stars Collide | When two stars collide and merge they form a new star that can stand out
against the background population in a starcluster as a blue straggler. In so
called collision runaways many stars can merge and may form a very massive star
that eventually forms an intermediate mass blackhole. We have performed
detailed evolution calculations of merger remnants from collisions between main
sequence stars, both for lower mass stars and higher mass stars. These stars
can be significantly brighter than ordinary stars of the same mass due to their
increased helium abundance. Simplified treatments ignoring this effect give
incorrect predictions for the collision product lifetime and evolution in the
Hertzsprung-Russell diagram.

710.1735 | Static black hole solutions with a self interacting conformally coupled
scalar field | We study static, spherically symmetric black hole solutions of the Einstein
equations with a positive cosmological constant and a conformally coupled self
interacting scalar field. Exact solutions for this model found by
Mart{\'\i}nez, Troncoso, and Zanelli, (MTZ), were subsequently shown to be
unstable under linear perturbations, with modes that diverge arbitrarily fast.
We find that the moduli space of static, spherically symmetric solutions that
have a regular horizon -and satisfy the weak and dominant energy conditions
outside the horizon- is a singular subset of a two dimensional space
parameterized by the horizon radius and the value of the scalar field at the
horizon. The singularity of this space of solutions provides an explanation for
the instability of the MTZ spacetimes, and leads to the conclusion that, if we
include stability as a criterion, there are no physically acceptable black hole

710.1738 | Modified f(R) gravity unifying R^m inflation with \LambdaCDM epoch | We consider modified $f(R)$ gravity which may unify $R^m$ early-time
inflation with late-time $\Lambda$CDM epoch. It is shown that such model passes
the local tests (Newton law, stability of Earth-like gravitational solution,
very heavy mass for additional scalar degree of freedom) and suggests the

cascade regime. Focusing on the statistics of Lagrangian tracer particles,
scaling behavior of the probability density functions of velocity fluctuations
is investigated. The results are compared to the three-dimensional case. In
particular an analysis in terms of compensated cumulants reveals the transition
from a strong non-Gaussian behavior with large tails to Gaussianity. The
reported computation of correlation functions for the acceleration components
sheds light on the underlying dynamics of the tracer particles.

710.1741 | Semileptonic D-decays and Lattice QCD | We explore four different strategies to extract the D-meson semileptonic
decay form factors from the Green functions computed in QCD numerically on the
lattice. From our numerical tests we find that two such strategies, based on
the use of double ratios of 3-point correlation functions, lead to an
appreciable reduction of systematic uncertainties. This is an important step in
reducing the overall uncertainty in the lattice QCD results for the D-decay
form factors which are needed to determine the CKM entries |Vcd| and |Vcs|

we found that there is no heavy Majorana neutrino mass matrix to be invariant
in form under a cyclic permutation. But, by imposing an additional assumption
that at least one of the 2x2 sub-matrices of heavy Majorana neutrino mass
matrix inverse having zero determinant, we found that only two of the eight
possible patterns for heavy Majorana neutrino mass matrices to be invariant
under a cyclic permutation. One of the two invariant heavy Majorana neutrino
mass matrices could produces neutrino mass matrix $M_{\nu}$ that can be used to
explain the neutrino mixing phenomena for both solar and atmospheric neutrinos

710.1744 | Quantum problem solving as simultaneous computation | I provide an alternative way of seeing quantum computation. First, I describe
an idealized classical problem solving machine that, thanks to a many body
interaction, reversibly and nondeterministically produces the solution of the
problem under the simultaneous influence of all the problem constraints. This
requires a perfectly accurate, rigid, and reversible relation between the
coordinates of the machine parts - the machine can be considered the many body
generalization of another perfect machine, the bounching ball model of
reversible computation. The mathematical description of the machine, as it is,
is applicable to quantum problem solving, an extension of the quantum
algorithms that comprises the physical representation of the problem-solution
interdependence. The perfect relation between the coordinates of the machine
parts is transferred to the populations of the reduced density operators of the
parts of the computer register. The solution of the problem is reversibly and
nondeterministically produced under the simultaneous influence of the state
before measurement and the quantum principle. At the light of the present

710.1745 | The GBT350 Survey of the Northern Galactic Plane for Radio Pulsars and
Transients | Using the Green Bank Telescope (GBT) and Pulsar Spigot at 350MHz, we have
surveyed the Northern Galactic Plane for pulsars and radio transients. This
survey covers roughly 1000 square degrees of sky within 75 deg < l < 165 deg
and |b| < 5.5 deg, a region of the Galactic Plane inaccessible to both the
Parkes and Arecibo multibeam surveys. The large gain of the GBT along with the
high time and frequency resolution provided by the Spigot make this survey more
sensitive by factors of about 4 to slow pulsars and more than 10 to millisecond
pulsars (MSPs), compared with previous surveys of this area. In a preliminary,
reduced-resolution search of all the survey data, we have discovered 33 new
pulsars, almost doubling the number of known pulsars in this part of the
Galaxy. While most of these sources were discovered by normal periodicity
searches, 5 of these sources were first identified through single, dispersed
bursts. We discuss the interesting properties of some of these new sources.
Data processing using the data's full-resolution is ongoing, with the goal of
uncovering MSPs missed by our first, coarse round of processing.

710.1746 | Field Theory on Nonanticommutative Superspace | We discuss a deformation of the Hopf algebra of supersymmetry (SUSY)
transformations based on a special choice of twist. As usual, algebra itself
remains unchanged, but the comultiplication changes. This leads to the deformed
Leibniz rule for SUSY transformations. Superfields are elements of the algebra
of functions of the usual supercoordinates. Elements of this algebra are
multiplied by using a $\star$-product which is noncommutative, hermitian and
finite when expanded in power series of the deformation parameter. Chiral
fields are no longer a subalgebra of the algebra of superfields. One possible
deformation of the Wess-Zumino action is proposed and analysed in detail.

710.1747 | Manifold and metric in numerical solution of the quasi-static
electromagnetic boundary value problems | Classical vector analysis is the predominant formalism used by engineers of
computational electromagnetism, despite the fact that manifold as a theoretical
concept has existed for a century. This paper discusses the benefits of
manifolds over the traditional approach in practical problems of modelling.
With a structural approach, it outlines the role and interdependence of
coordinate systems, metric, constitutive equations, and fields, and relates
them to practical problems of quasi-static computational electromagnetics: mesh
generation, open-boundary problems, and electromagnetic-mechanical coupled
problems involving motion and deformation. The proposed procedures also imply
improvements to the flexibility of the modelling software.

710.175 | 3000 % high-field magnetoresistance in super-lattices of CoFe
nanoparticles | We report on magnetotransport measurements on millimetre-large super-lattices
of CoFe nanoparticles surrounded by an organic layer. Electrical properties are
typical of Coulomb blockade in three dimensional arrays of nanoparticles. A
large high-field magnetoresistance, reaching up to 3000 %, is measured between
1.8 and 10 K. This exceeds by two orders of magnitude magnetoresistance values
generally measured in arrays of 3d metals ferromagnetic nanoparticles. The
magnetoresistance amplitude scales with the magnetic field / temperature ratio
and displays an unusual exponential dependency with the applied voltage. The
magnetoresistance abruptly disappears below 1.8 K. We propose that the
magnetoresistance is due to some individual paramagnetic moments localized
between the metallic core of the nanoparticles, the origin of which is
discussed.

710.1751 | Effective string theory description of the interface free energy | We compare the predictions of the Nambu-Goto effective string model with a
set of high precision Monte Carlo results for interfaces with periodic boundary
conditions in the 3D Ising model. We compute the free energy in the covariant
gauge exactly, up to the inclusion of the Liouville mode. The perturbative
expansion of this result agrees both with the result evaluated several years
ago by Dietz and Filk in the physical gauge and with a recent calculation with
the Polchinski-Strominger action. We also derive the effective string spectrum
which, because of the different boundary conditions, is very different from the
well known one of Arvis. Taking into proper account the effective string
corrections and exploiting some technical improvements in the simulations we
obtain precise estimate of the amplitude ratios T_c/\sqrt{sigma},
m_{0++}/\sqrt{\sigma} and sigma xi_{2nd}^2. We also discuss the behaviour of
the effective string free energy in the dimensional reduction limit (i.e., near

710.1752 | The formation and evolution of very massive stars in dense stellar
systems | The early evolution of dense stellar systems is governed by massive single
star and binary evolution. Core collapse of dense massive star clusters can
lead to the formation of very massive objects through stellar collisions
($M\geq$ 1000 \msun). Stellar wind mass loss determines the evolution and final
fate of these objects, and decides upon whether they form black holes (with
stellar or intermediate mass) or explode as pair instability supernovae,
leaving no remnant. We present a computationaly inexpensive evolutionary scheme
for very massive stars that can readily be implemented in an N-body code. Using
our new N-body code 'Youngbody' which includes a detailed treatment of massive
stars as well as this new scheme for very massive stars, we discuss the
formation of intermediate mass and stellar mass black holes in young starburst
regions. A more detailed account of these results can be found in Belkus et al.
2007.
