Similarities between basic mechanisms of cosmic and biologic systems

Similarities in the birth and development of cosmic and biologic systems provide unexpected proof for the major theories of formation of the universe - the Big Bang and the String theories. They include similarities in the theory of their formation, one unit origin, preexisting states, conception, fertilization, gestation, information, basic units, flatness, fluctuations, smoothness, lumpiness, reproductive and...

Theoretical calculation of half-metallic ferromagnetism in Al1-xVxN compound

Using the first-principles in the framework of density functional theory, the structural properties, electronic structure, and magnetism of V-doped aluminum nitride (AlN) were investigated. The calculations were carried out using the method based on pseudopotential, employed exactly as implemented in Quantum ESPRESSO code. For (x = 6.25%) Al0.9375V0.0625N and (x = 12.5%) Al0.875V0.125N concentrations, a half-metallic...
