Europa's Neutral Sodium Exosphere Is Quasi‐Stable Over Decades
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Europa's sodium cloud is thought to be modified by its orbital longitude and by its plasma environment, which modulates with Jovian magnetic geometry. To explore and quantify sodium cloud variability, seven sets of Keck I/HIRES measurements are compared providing comprehensive coverage of orbital and magnetic geometry.

BALLISTICS FOR THE NEUROSURGEON
Neurosurgery, 2008Craniocerebral injuries from ballistic projectiles are qualitatively different from injuries in unconfined soft tissue with similar impact. Penetrating and nonpenetrating ballistic injuries are influenced not only by the physical properties of the projectile, but also by its ballistics. Ballistics provides information on the motion of projectiles while

Observation of ballistic holes
Physical Review Letters, 1988We report the first direct observation of ballistic hole transport in semiconductors, via energy spectroscopy experiments. Light holes are preselected and injected via tunnelling into 31 nm thick p+ GaAs layers. About 10% of the injected holes have been found to traverse ballistically maintaining distributions ≈ 35 meV wide, with a mean free path of ...

Ballistic Trauma: Overview and Statistics – Wound Ballistics
2016Wound ballistics is the specialty in ballistics dealing with the interaction of bullet and tissue, resulting in lesions when humans or animals are hit. The lesions depend on the velocity and mass of the bullet as well as its design. Bullets are divided into low- and high-velocity bullets.

Wound profiles made under controlled conditions in the wound ballistics laboratory at the Letterman Army Institute of Research showed the location along their tissue path at which projectiles cause tissue disruption and the type of disruption (crush from direct contact with the projectile or stretch from temporary cavitation).
