determination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولParallel preoptic pathways for thermoregulation.
Sympathetic premotor neurons in the rostral medullary raphe (RMR) regulate heat conservation by tail artery vasoconstriction and brown adipose tissue thermogenesis. These neurons are a critical relay in the pathway that increases body temperature. However, the origins of the inputs that activate the RMR during cold exposure have not been definitively identified. We investigated the afferents to...
متن کاملMapping pathways from stress to cancer progression.
U sing in vitro, animal, and human clinical approaches, researchers are beginning to understand the relationship between psychological stress and cancer progression at the biochemical and molecular levels. The focus of many of these studies is basic biology — the experience of stress and changes in gene expression that may be associated with tumor progression. “We’re very much interested in tak...
متن کاملParallel pathways in cytochrome c(551) folding.
The folding of cytochrome c(551) from Pseudomonas aeruginosa was previously thought to follow a simple sequential mechanism, consistent with the lack of histidine residues, other than the native His16 heme ligand, that can give rise to mis-coordinated species. However, further kinetic analysis reveals complexities indicative of a folding mechanism involving parallel pathways. Double-jump interr...
متن کاملHow parallel are the primate visual pathways?
The visual system, like all sensory systems, contains parallel pathways (see Stone 1983). Recently, much emphasis has been placed on the relationship between two subcortical and two cortical pathways. It has been suggested that the cortical and subcortical pathways are continuous, so that distinct channels of information that arise in the retina remain segregated up to the highest levels of vis...
