SUMMARY To constrain seismic anisotropy under and around the Alps in Europe, we study SKS shear wave splitting from region densely covered by AlpArray network. We apply a technique based on measuring intensity, constraining well both fast orientation delay. Four years of teleseismic earthquake data were processed, 723 temporary permanent broad-band stations deployment including ocean-bottom sei...

INTRODUCTION Studies have shown that low peak wall shear stress (WSS) contributes to the formation of atherosclerotic plaques [1]. Additionally, Lee et al. demonstrated that low peak WSS correlates with high atherosclerotic indices [2]. However, the magnitude of WSS in older subjects, who have a greater incidence of atherosclerosis, requires further investigation. The purpose of this study was ...

S U M M A R Y The variation of frequency-dependent seismic wave attenuation with direction (attenuation anisotropy) contains additional information to that contained in velocity anisotropy. In particular, it has the potential to distinguish between different mechanisms that can cause velocity anisotropy. For example, aligned fracturing might be expected to cause measurable velocity and attenuat...

INTRODUCTION Time-resolved 3-dimensional phase-contrast MR imaging (3D-PC MRI) has developed as an active area of research for vascular imaging [1]. The ability to acquired directional flow information along all three principle axes has led to investigations of the role of altered hemodynamics in vascular pathologies[2], quantification of flow in the major intracranical vessels [3], and researc...

New shear wave splitting measurements made from stations onshore and offshore the South Island of New Zealand show a zone of anisotropy 100–200km wide. Measurements in central South Island and up to approximately 100 km offshore from the west coast yield orientations of the fast quasi-shear wave nearly parallel to relative plate motion, with increased obliquity to this orientation observed fart...

We estimate shear-wave velocities in the shallow subsurface throughout Japan by applying seismic interferometry to the data recorded with KiK-net, a strongmotion network in Japan. Each KiK-net station has two receivers; one receiver on the surface and the other in a borehole. By using seismic interferometry, we extract the shear wave that propagates between these two receivers. Applying this me...

There has recently been considerable interest in the acoustics of fluid-saturated porous media. The most interesting peculiarity, the existence of two compressional waves, was first predicted by Biot [1] in 1956. It was not until 1980 that Plona [2] experimentally observed the additional slow compressional bulk wave in a water-saturated porous solid composed of sintered glass spheres. Even more...

The interaction of open and coastal oceans in a midlatitude ocean basin is investigated in light of Rossby and coastal Kelvin waves. The basinwide pressure adjustment to an initial Rossby wave packet is studied both analytically and numerically, with the focus on the low-frequency modulation of the resulting coastal Kelvin wave. It is shown that the incoming mass is redistributed by coastal Kel...
