Endothelial YAP Signaling Promotes Blood‐Spinal Cord Barrier Repair in Mice After Spinal Cord Injury

Advanced Science, EarlyView.
Endothelial YAP is required for blood‐spinal cord barrier repair after spinal cord injury. YAP‐dependent vascular repair is associated with ANGPT1/PI3K/AKT signaling in vivo and may involve endothelial‐pericyte paracrine interactions. By supporting vascular remodeling, tight junction restoration, restored pericyte coverage, and astrocyte‐vascular ...

Numerical Assessment of the Efficacy of Various Exhaust Muffler Liner Materials on Acoustical Performance

Journal of Engineering
Noise levels have rapidly increased in recent years, largely due to the proliferation of modern appliances and critical noise sources like engine exhaust mufflers. Controlling muffler-radiated noise could reduce its impact on the surrounding communities.

Sound Transmission Loss of Complex Single Panels [PDF]

The Journal of the Acoustical Society of America, 1971
Frequently, the transmission loss of panels must be estimated from limited data for use in design problems. Usually, the panels involve complex constructions where the assumptions of single-panel theory cannot be reasonably applied. A simplified analysis of the dynamics of some complex panels is presented which leads to a straight-forward prediction ...
