Heart Failure Associated With Ventricular Septal Defect, Mitral Valve Prolapse, Non-stenotic Bicuspid Aortic Valve, and Patent Foramen Ovale.

Ventricular septal defect (VSD) and bicuspid aortic valve (BAV) are the two most common congenital heart defects. BAV may occur sporadically or in association with other cardiac malformations. VSDs have decreased incidence in the adult population due to spontaneous closure.

Modal control of mechanically coupled NEMS arrays for tunable RF filters.

A novel tuning strategy of nanoelectromechanical systems (NEMS)-based filters is proposed based on the modal control of mechanically coupled NEMS arrays. This is done by adjusting separately addressed distributed actuation and detection configurations proportionally to desired modal vectors. This control scheme enhances the global output signal, raising the power handling of the filter on all channels.
