The Sonic RAREFACTION WAVE GUN (RAVEN) is a Projectile Launch Method that achieves: – Unprecedented Reductions in Recoil Impulse. It can shoot faster, cooler and can be lighter than a current gun ...

Dementia in chronic traumatic encephalopathy (CTE) was tied to neuropathologic changes associated with exposure to repetitive head impact -- including white matter rarefaction and phosphorylated tau - ...

The control of small structures and fast modes needs not only more accurate values in the commonly used dimensions (, u, T, P), but also, in fact more essentially, the controls from more dimensions.

Rarefaction has long represented a powerful tool for detecting species richness and its variation across spatial scales. Some authors recently reintroduced the mathematical expression for calculating ...
