Focus on: “G protein-dependent activation of smooth muscle eNOS via natriuretic peptide clearance receptor”
coordinated contraction and relaxation of gut smooth muscle are essential for normal swallowing, gastric emptying, intestinal propulsion, and defecation. Relaxation of gastrointestinal smooth muscle is brought about by the action of inhibitory substances released by enteric nerves and other cells
Genetic simulated annealing algorithm coupled with niche is applied to search rock slope's critical slip surface in this study.Based on the slope structural plane simulation,the genetic simulated annealing algorithm coupled with niche can search the critical slip composed of the joints and rock-bridges.Compared with other intelligent algorithms,it has the merit of faster convergence rates and can find all extremes in a short time without strict requests for parameters.
