The strength of transverse flow is examined as a function of transverse momentum p t using a simple, transversely moving thermal model and a more realistic, relativistic transport model (ART). It is shown that the p t dependence reveals useful information about the collective flow that is complementary to that obtained from the standard in-plane transverse momentum analysis. Interesting feature...

Recent results on identified hadrons from the PHENIX experiment in Au+Au collisions at mid-rapidity at √ sNN = 200 GeV are presented. The centrality dependence of transverse momentum distributions and particle ratios for identified charged hadrons are studied. The transverse flow velocity and freeze-out temperature are extracted from pT spectra within the framework of a hydrodynamic collective ...

BACKGROUND AND PURPOSE Second harmonic imaging (SHI) is a novel ultrasound technique that allows the evaluation of brain tissue perfusion. The purpose of this study was to assess normal cerebral echo contrast characteristics in 3 regions of interest (ROIs) in the transverse axial and coronal insonation planes through the temporal bone window. Materials and Methods- SHI examinations were perform...
