High-Enthalpy Test Environments, Flow Modeling and in Situ Diagnostics for Characterizing Ultra-High Temperature Ceramics
We describe the test environments generated by two types of these ground test facilities – subsonic inductively coupled plasma tunnels and supersonic arc-jet tunnels – and discuss the important roles of computational fluid dynamics modeling and in situ optical diagnostics for interpreting test results from a materials science perspective.

All Shocked Meteorites Were Shocked at Significant Depth in Their Parent Bodies
We have recently realized that it is virtually impossible for a meteorite to survive strong shock unless it is well below the surface of a parent body.

Callosal Microstructural Abnormalities in Alzheimer’s Disease and Alcoholism: Same Phenotype, Different Mechanisms
Magnetic resonance and diffusion tensor imaging data were acquired and midsagittal area, length, dorsoventral height, fractional anisotropy, and mean diffusivity of the total corpus callosum and volume of the lateral ventricles were measured.
