Surface wave dispersion measurements for Love wave overtones carry evidence of azimuthal anisotropy in the transition zone of Earth's mantle (400 to 660 kilometers deep). A Backus-Gilbert inversion of anisotropic phase velocity maps, with resolution kernels mainly sensitive to the transition zone, shows a robust long-wavelength azimuthally anisotropic velocity structure. This observation puts n...

The corundum structure is rhombohedral/trigonal and thus has lower symmetry than the well-investigated hexagonal crystals such as wurtzite GaN- ZnO-based materials. By investigating growth of ?-phase ( Al x Ga 1 ? ) 2 O 3 alloy thin films on various orientations Al2O3 substrates, anisotropy around [00.1]-axis investigated. In particular, pseudomorphic r plane (01.2) ? (10.2) substrates compared...

We present the results of a study of surface wave dispersion across the Arctic region (>60◦N) and compare the estimating group velocity maps with new maps of the body wave phases Pn and Sn. Data recorded at about 250 broadband digital stations from several global and regional networks were used to obtain Rayleigh and Love wave group velocity measurements following more than 1100 events with mag...

A persistent reversal in the expected polarity of the initiation of vertically polarized shear waves that graze the D'' layer (the layer at the boundary between the outer core and the lower mantle of Earth) in some regions starts at the arrival time of horizontally polarized shear waves. Full waveform modeling of the split shear waves for paths beneath the Caribbean requires azimuthal anisotrop...

Measurements of azimuthal distribution of inclusive photons using the fine granularity preshower photon multiplicity detector (PMD) at CERN SPS are used to obtain anisotropy in the azimuthal distributions. These results are used to estimate the anisotropy in the neutral pion distributions. The results are compared with results of charged particle data, both for first order and second order anis...

Over the last one decade, elliptic flow in ultrarelativistic heavy ion collisions has become an important probe of the dynamics of the system [1]. The elliptic flow manifests itself as an anisotropy in the azimuthal distributions of transverse momentum of the emitted particles. The azimuthal distributions are expanded in a Fourier series where the coefficients of expansion are the measures of d...

Abstract. I investigate the correlation between spatial and flow anisotropy in determining the elliptic flow and azimuthal dependence of the HBT correlation radii in non-central nuclear collisions. It is shown that the correlation radii are in most cases dominantly sensitive to the anisotropy in space. In case of v2, the correlation depends strongly on particle species. A procedure for disentan...
