Sound velocities of majorite garnet and the composition of the mantle transition regiona
Article Abstract:
Several in situ ultrasonic measurements are conducted to determine the relationship between the sound velocities of majorite garnet and the composition of the mantle transition region. The results show that the sound velocities of majorite in a pyrolite composition are extremely low, which leads to a decrease in the shear-wave velocity at high temperatures.

A constitutive law for dense granular flows
Article Abstract:
A new constitutive relation for dense granular flows is proposed by testing a three-dimensional (3D) model through experiments on granular flows on a pile between rough sidewalls, in which a complex 3D flow pattern develops. It is shown that, without any fitting parameter, the model gives quantitative predictions for the flow shape and velocity profiles.

The ultimate speed of magnetic switching in granular recording media
Article Abstract:
In magnetic memory devices, selectively setting the magnetization vector of individual magnetic domains either 'up' or 'down', record logical bits. The fastest and most efficient recording method involves precessional switching.
