Although the role of laparoscopic cholecystectomy (LC) as a safe and cost effective procedure has been ascertained, its role in the geriatric population, the majority of whom present with coexistent diseases, has yet to be defined. We retrospectively reviewed outcome parameters of 144 consecutive patients over age 65 undergoing LC, for both acute(More)
PURPOSE This Phase II treatment study examined the effect of Verb Network Strengthening Treatment (VNeST) on individuals with moderate-to-severe aphasia. Research questions addressed (a) pre- to posttreatment changes and pretreatment to treatment phase changes on probe sentences containing trained verbs (e.g., "The carpenter is measuring the stairs") and(More)
This paper investigates the optimization of design parameters to achieve enhanced modulation efficiency and cutoff frequency in AlGaN/InGaN/GaN HEMTs. The frequency dependent current gain of the device is simulated for different AlGaN thicknesses, taking into account the polarization fields and strain effects. The implementation of an underlap junction is(More)
