STUDY DESIGN An in vitro biomechanical study of the stabilizing effects of a different combination of cages and transpedicular instrumentation on experimental degenerative disc disease. OBJECTIVES To evaluate the biomechanical efficacy of the interbody fusion cage and unilateral posterior instrumentation on the stability of the spine-device construct. (More)
The coverage problem is a fundamental and important issue with regard to wireless sensor networks. To reduce the number of sensor nodes, mobile nodes can be used to mitigate the sweep coverage problem. In this paper, a sweep coverage mechanism is proposed to keep the patrol times of mobile nodes approximate to one another. In simulation, various moving(More)
