Simplicial and ∆-structures of configuration spaces are investigated. New connections between the homotopy groups of the 2-sphere and the braid groups are given. The higher homotopy groups of the 2-sphere are shown to be derived groups of the braid groups over the 2-sphere. Moreover the higher homotopy groups of the 2-sphere are shown to be isomorphic to(More)
The ability to quantify pain intensity is essential when caring for individuals in pain in order to monitor patient progress and analgesic effectiveness. Three scales are commonly employed: the simple descriptor scale (SDS), the visual analog scale (VAS), and the numeric (pain intensity) rating scale (NRS). Patients with English as a second language may not(More)
OBJECT The purpose of this case review was to identify and analyze existing wrong-site craniotomy (WSC) cases to determine the factors that contributed to the errors and to suggest preventative strategies for WSC. Wrong-site surgery (WSS) is a devastating surgical error that has gained increased public attention in recent years due to some high-profile(More)
