Previous studies had demonstrated that small amplitude muscle vibration (MV) could increase the motor pathway excitability of the vibrated hand muscle and inhibit the excitability motor pathways of neighboring muscles in healthy individuals. The purpose of this study is to examine whether the vibration-induced neurophysiological changes reflect in the voluntary control of finger movements. We tested the hypothesis that MV to individual hand muscle (abductor pollicis brevis, APB; first dorsal interosseus, FDI; or abductor digiti minimi, ADM) affects the control of finger abduction/adduction. Each fingertip position was captured using a motion capture system during four experiment conditions: no MV, MV to APB, MV to FDI, and MV to ADM. Two consecutive 10-s trials in each condition were tested for each finger. We calculated individuation index (find) and index of selective activation (ISA) to compare finger independency with and without MV. The results indicated that muscle vibration could enhance the independency of finger movements.

Microwave annealing of dopants in Si has been reported to produce highly activated junctions at temperatures far below those needed for comparable results using conventional thermal processes. However the details of the kinetics and mechanisms for microwave annealing are far from well understood. Comparisons between MWA and RTA of dopants in implanted Si has been investigated to produce highly activated junctions. First, As, P-31, and BF2 implants in Si substrate were annealed by MWA at temperatures below 550 degrees C.
