An optimal algorithm to do probe selection in causal chains is presented. Probes may have different costs of measurement. The algorithm runs in polynomial time. This research was supported in part by the Ballistic Missile Defense Advanced Technology Center under contract #DASG60-86-C-0015, the Office of Naval Research, under Agreement #N00014-85-K-0008 and the Defense Advanced Research Projects...

The purpose of this study was to investigate the influence of a single static, ballistic, or proprioceptive neuromuscular facilitation (PNF) stretching exercise on the various muscle-tendon parameters of the lower leg and to detect possible differences in the effects between the methods. Volunteers (n = 122) were randomly divided into static, ballistic, and PNF stretching groups and a control g...

Ballistic chorea (hemichorea–hemiballism) localizes to the subthalamic nucleus and its connections (video 1, figure, Aa) or the putamen (video 2, figure, Ab). Other large-amplitude hyperkinetic lesional movements can have similarly high localizing value. “Ballistic” tremor may develop months after recovering from ventrolateral thalamic strokes, in the thalamogeniculate vascular territory (video...

The Rajendran-Grove (RG) ceramic damage model is a three-dimensional internal variable based constitutive model for ceramic materials, with the considerations of micro-crack extension and void collapse. In the present paper, the RG ceramic model is implemented into the newly developed computational framework based on the Meshless Local Petrov-Galerkin (MLPG) method, for solving high-speed impac...
