Reshaping-induced spatiotemporal chaos in driven, damped sine-Gordon systems
Spatiotemporal chaos arising from the competition between
sine-Gordon-breather and kink-antikink-pair solitons by reshaping an ac force
is demonstrated. After introducing soliton collective coordinates, Melnikov's
method is applied to the resulting effective equation of motion to estimate the
parameter-space regions of the ac force where homoclinic bifurcations are
induced. The analysis reveals that the chaos-order threshold exhibits
sensitivity to small changes in the force shape. Computer simulations of the
sine-Gordon system show good agreement with these theoretical predictions.Comment: 11 pages, 3 figure
Ghrelin and Functional Dyspepsia
The majority of patients with dyspepsia have no identifiable cause of their disease, leading to a diagnosis of functional dyspepsia (FD). While a number of different factors affect gut activity, components of the nervous and endocrine systems are essential for normal gut function. Communication between the brain and gut occurs via direct neural connections or endocrine signaling events. Ghrelin, a peptide produced by the stomach, affects gastric motility/emptying and secretion, suggesting it may play a pathophysiological role in FD. It is also possible that the functional abnormalities in FD may affect ghrelin production in the stomach. Plasma ghrelin levels are reported to be altered in FD, correlating with FD symptom score. Furthermore, some patients with FD suffer from anorexia with body-weight loss. As ghrelin increases gastric emptying and promotes feeding, ghrelin therapy may be a new approach to the treatment of FD
