Noninvasive Focal Gene Delivery into the Cerebellum of Non‐Human Primates using Focused Ultrasound

Advanced Science, EarlyView.
Focal and non‐invasive viral vector delivery in non‐human primates remains a major challenge in translational neuroscience. Low‐intensity focused ultrasound was used to transiently open the blood–brain barrier and enable targeted gene delivery to the cerebellum.

Simple Rules for Cavitation Instabilities in Turbomachinery

, 2001
The present paper focuses on the correlation of cavitation instabilities in turbomachinery with steady cavity length, or a parameter sigma/(2*alpha). A linear stability analysis shows that various types of cavitation instabilities start to occur when the
