— Reducing energy consumption has been a recent focus of wireless sensor network research. Topology control explores the potential that a dense network has for energy savings. One such approach is Geographic Adaptive Fidelity (GAF) [1]. GAF is proved to be able to extend the lifetime of self-configuring systems by exploiting redundancy to conserve energy(More)
We previously demonstrated that human osteosarcoma cells (SAOS-2) induce contact-dependent apoptosis in endothelium, and expected similar apoptosis in human gingival fibroblasts (h-GF) using SAOS-2 alkaline phosphatase (AP) to identify cells. However, h-GF apoptosis did not occur, despite reduction in AP-negative h-GF number (p < 0.01) and enhancement of(More)
