A new transformation method is developed using the general sine-Gordon travelling wave reduction equation and a generalized transformation. With the aid of symbolic computation, this method can be used to seek more types of solutions of nonlinear differential equations, which include not only the known solutions derived by some known methods but new solutions. Here we choose the double sine-Gor...

Global city should also include the dimensions of the leading role and capacity on health improvements and well-being promotion.

T heoretical and modeling assessments consistently point toward an increase in hurricane intensity with global warming (1–3). For the North Atlantic, the annual number of the most intense hurricanes has been predicted to increase by more than 50% for each 1-°C increase in surface temperatures (2, 4). However, there is no consensus on whether current hurricanes have responded to the substantial ...

G iven the burden of type 2 diabetes and its complications, much attention has been given to prevention, beginning with identifying at-risk individuals prior to diagnosis. This has led to the designation of “prediabetes,” which is an intermediate form of dysglycemia on a spectrum ranging from normal to overt diabetes. The American Diabetes Association defines prediabetes as a fasting glucose of...
