Homogeneous comparison of planet candidates imaged directly until 2008
We present a compilation of the planet candidates currently known from direct
imaging. We have gathered available data from the literature and derive the
luminosity of all candidates in a homogeneous way using a bolometric
correction, the distances and the K band magnitudes of the objects. In a final
step we find the masses of the candidates from a comparison of the luminosity
or, if not available, an absolute brightness and several well known hot-start
evolutionary models.Comment: 4 pages, 1 figure, Proceedings of the 2nd Subaru International

Analyses of collective flow and space-time evolution based on relativistic hydrodynamical model
We numerically solve fully (3+1)-dimensional relativistic hydrodynamical
equation with the baryon number conservation law. For realistic initial
conditions we adopt the results from the event generator (URASiMA). Using this
model we discuss collective flow.Comment: 4 pages, 11 figures, to apper in Proceedings of Quark Matter '9

Hard x-ray spectroscopy in NaxCoO2 and superconducting NaxCoO2 - yH2O: A view on the bulk Co electronic properties
The electronic properties of Co in bulk Na0.7CoO2 and the superconducting
hydrated compound Na0.35CoO2 - y H2O have been investigated by x-ray absorption
spectroscopy (XAS) and resonant inelastic x-ray scattering (RIXS) using hard
x-rays. The XAS spectra at the Co K-edge were measured in both compounds with
two different polarization directions. The changes in the XAS spectra upon
hydration and their polarization dependence are well accounted for by linear
muffin- tin orbital calculations in the local density approximation. The
underlying electronic structure indicates the strong hybridization between the
Co 3d and O 2p states in both compounds, while the electron localization is
enhanced in the hydrated compound due to the increase of the Co-Co interplanar
distance. The Co K pre-edge further highlights the splitting of the d band as a
result of the crystal field effect and demonstrates the Co valency increase
when Na0.7CoO2 is hydrated. The RIXS spectra measured at the Co K-edge show an
energy loss feature around 10 eV in both compounds in fair agreement with the
calculated dynamical structure factor. The RIXS feature is associated to a
damped plasmon excitation.Comment: 8 page

Global Existence Results and Uniqueness for Dislocation Equations
We are interested in nonlocal Eikonal Equations arising in the study of the
dynamics of dislocations lines in crystals. For these nonlocal but also non
monotone equations, only the existence and uniqueness of Lipschitz and
local-in-time solutions were available in some particular cases. In this paper,
we propose a definition of weak solutions for which we are able to prove the
existence for all time. Then we discuss the uniqueness of such solutions in
several situations, both in the monotone and non monotone case
Spin-Peierls instability in a quantum spin chain with Dzyaloshinskii-Moriya interaction
We analysed the ground state energy of some dimerized spin-1/2 transverse XX
and Heisenberg chains with Dzyaloshinskii-Moriya (DM) interaction to study the
influence of the latter interaction on the spin-Peierls instability. We found
that DM interaction may act either in favour of the dimerization or against it.
The actual result depends on the dependence of DM interaction on the distortion
amplitude in comparison with such dependence for the isotropic exchange
interaction.Comment: 12 pages, latex, 3 figure
