The GPR-based estimation of the volumetric ice content of dispersed ground in the Central Yakut lowland

open access: yesЛëд и снег, 2019
The previously unknown dependence between the volume ice content of frozen dispersed soils and their radiophysical properties (the speed of propagation and specific attenuation of the amplitude of electromagnetic waves) was studied in the layer of annual

Information transport by sine-Gordon solitons in microtubules

open access: yes, 2001
We study the problem of information propagation in brain microtubules. After considering the propagation of electromagnetic waves in a fluid of permanent electric dipoles, the problem reduces to the sine-Gordon wave equation in one space and one time ...
