ENETIC recombination is a natural source of variation. Experiments with chromosomes of Drosophila pseudoobscura, D. prosaltans, D. persimilis, D. willistoni, and D. melanogaster with quasinormal viability show increases in the variation of viability values for homozygotes after recombination between strains ( SPASSKY, SPASSKY, LEVENE, and DOBZHANSKY 1958; DOBZHANSKY, LEVENE, SPASSKY, and SPASSK...

PURPOSE We examined the face, content and construct validity of version 1.0 of the University of Washington transurethral prostate resection (TURP) trainer. MATERIALS AND METHODS Version 1.0 of a virtual reality based simulator for transurethral skills was developed at our laboratory by integrating TURP hardware with our virtual 3-dimensional anatomy, irrigation control, cutting, bleeding and...

Neurons are notoriously noisy devices. Although the traditional view posits that noise degrades system performance, recent evidence suggests that noise may instead enhance neural information processing under certain conditions. Here we report that random channel and synaptic noise improve the ability of a biologically realistic computational model of the Hermissenda eye to encode light intensit...

INTRODUCTION The aim of this study was to evaluate, using cone-beam computed tomography (CBCT), transportation and centralization of different nickel-titanium (NiTi) rotary instruments. METHODS One hundred and twenty eight mandibular premolars were selected and instrumented using the following brands of NiTi files: WaveOne, WaveOne Gold, Reciproc, ProTaper Next, ProTaper Gold, Mtwo, BioRaCe a...
