BACKGROUND Computer-assisted learning (CAL) offers a number of potential advantages for surgical technical skills teaching. The purpose of this study was to evaluate the impact of individualized external feedback on surgical skill acquisition when a CAL package is used for instruction. METHODS Freshman and sophomore students participated in a 1-hour CAL(More)
Electroconvulsive therapy (ECT) is remarkably effective in severe major depressive disorder (MDD). Growing evidence has accumulated for brain structural and functional changes in response to ECT, primarily within cortico-limbic regions that have been considered in current neurobiological models of MDD. Despite increasing evidence for important cerebellar(More)
The conservation of the total current density in semiconductor devices implies that the current derives from a vector potential. The calculation of this current potential is a dual problem of the original device simulation problem. A simple and elegant discrete method is proposed for the 2-D case, which yields the current potential for a given, numerically(More)
