Exact Solutions to the Sine-Gordon Equation [PDF]

open access: yes, 2010
A systematic method is presented to provide various equivalent solution formulas for exact solutions to the sine-Gordon equation. Such solutions are analytic in the spatial variable $x$ and the temporal variable $t,$ and they are exponentially asymptotic

Radial frequency stimuli and sine-wave gratings seem to be processed by distinct contrast brain mechanisms

open access: yesBrazilian Journal of Medical and Biological Research, 2005
An assumption commonly made in the study of visual perception is that the lower the contrast threshold for a given stimulus, the more sensitive and selective will be the mechanism that processes it.
