The complex and chaotic dynamics of a one-dimensional plasma-filled diode is numerically explored by a particle-in-cell simulation. The system has just one control parameter, namely, the electron transit angle, and presents a complex behavior as a function of such a parameter. We report here the...

We present a cellular automata model developed to study the evolution of an infectivity nucleus in several conditions and for two kinds of epidemiologically different diseases. We analyse the role of the model parameters, concerning the epidemiological and demographic aspects of the problem, and...

The Korteweg–de Vries equation has been generalized by Rosenau and Hyman [Compactons: Solitons with finite wavelength, Phys. Rev. Lett. 70(5) (1993) 564] to a class of partial differential equations that has soliton solutions with compact support (compactons). Compactons are solitary waves...
