Dark energy cosmology is considered in a modified Gauss-Bonnet model of gravity with and without a scalar field. It is shown that these generalizations of General Relativity endow it with a very rich cosmological structure: ...

The results of muon flux measurements (E ≥ 70 MeV) in the atmosphere during solar activity min-imum are reported. The measurements were performed during Antarctic sea expedition in 1975–1976 at several geomagnetic locations ...

The cosmological solution with a long-term bouncing off time is presented. The solution has a preceding contracting and a subsequent expanding phases and between them there exists a bouncing off phase with arbitrary time ...

The cosmological solution with a long-term bouncing off time is presented. The solution has a preceding contracting and a subsequent expanding phases and between them there exists a bouncing off phase with arbitrary time duration.

On the basis of a great body of experimental data it was concluded [1] that neither s conduction electrons nor s valence holes undergo self-trapping in wide-gap (Eg > 5 eV) binary ionic crystals. On the other hand, the ...

Nearly monodisperse, mesoporous, colloidal silica spheres were treated with aminopropyltriethoxysilane and subsequently calcined to generate luminescent mesoporous colloidal silica (LMCS), with broad bimodal visible emission ...

It has been established experimentally that the magnetic state of austenite of a preliminarily com pletely austenitized chromium–nickel steel at the initial stage of the deformation induced martensitic trans formation ...

The impurity magneto-optical absorption for the cases of longitudinal and transversal light polarization with respect to the quantum wire axis has been theoretically studied. Analytical expressions for the corresponding ...

The results of numerous experiments on the uniaxial tension of metastable austenitic stainless steels [1–3] indicate that, from a certain critical strain (stress) to failure, the α' martensite (deformation-induced marten-site), ...
