A feynman path integral representation for elastic wave scattering by anisotropic weakly perturbations
We write a space-time Feynman path integral representation for scattered
elastic wave fields from a weakly compact supported anisotropic
non-homogeneity.Replacement by a new version where We (I!) propose a new
tomographic inversion methodology based solely in the wave sampling of the Ray
paths through Monte Carlo path integral sampling Holding thus great
potentiality for Navy's advanced Sonar detection .Comment: 8 page
Considerations on the Sulphonamides with a Use of Sulphones and Pyrimidine Derivative
Trials conducted with sulphones and sulphonamides combined with a pyrimidine derivative for the assessment of their value in the treatment of malaria are reported, and reasons for the use of one of these combinations - Maloprim - by the Malaria Service of Mozambique are presented.S.

Culture, nationality and demographics in ultimatum games
We use experimental data collected in Russia and in the United States using a simple ultimatum game to evaluate two alternative hypotheses that may account for previously observed behavior in multinational experiments. One hypothesis postulates that behavioral differences observed in bargaining experiments arise from country-specific cultural environments. We submit the alternative hypothesis that different behavior in such experiments stems from differences in the demographic characteristics of the subject pools within each country. Because of its simplicity, our experimental design allows us to discriminate between these two hypotheses. Our findings support the alternative hypothesis.multinational experiments, ultimatum bargaining
Vortex-Antivortex Lattice in Ultra-Cold Fermi Gases
We discuss ultra-cold Fermi gases in two dimensions, which could be realized
in a strongly confining one-dimensional optical lattice. We obtain the
temperature versus effective interaction phase diagram for an s-wave superfluid
and show that, below a certain critical temperature T_c, spontaneous
vortex-antivortex pairs appear for all coupling strengths. In addition, we show
that the evolution from weak to strong coupling is smooth, and that the system
forms a square vortex-antivortex lattice at a lower critical temperature T_M.Comment: Submitted to Physical Review Letter
