Modeling the Operation of a Sensor Unit in a Monitoring Device for the Parameters of Cosmic Ray Fluxes
Measurement Techniques. 2016. Vol. 59. No. 8. P. 884-891.
A mathematical model is developed for a multichannel sensor unit based on diamond detectors in a device for monitoring the parameters of cosmic ray fluxes. The output signals from these sensors are modelled as they detect ionizing radiation from outer space in different spacecraft orbits with various levels of solar activity.

Evolution of solitons is addressed in the framework of an extended nonlinear Schrödinger equation (NLSE), including a pseudo-stimulated-Raman-scattering (pseudo-SRS) term, i.e., a spatial-domain counterpart of the SRS term which is well known as an ingredient of the temporal-domain NLSE in optics. In the present context, it is induced by the underlying interaction of the high-frequency ...

We present constraints on physical conditions in diffuse HD/H2-bearing molecular clouds using measured HD/H2 column density ratio. We used recently published formalism that describes how this ratio changes with ultraviolet field intensity, number density and cosmic ray ionization rate. Out of them the most important parameter is the cosmic ray ionization rate, as it determines the ...

Size-dependent quantization of energy spectrum of conducting electrons in solids leads to oscillating
dependence of electronic properties on corresponding dimension(s). In conventional metals with typical
energy Fermi EF~1 eV and the charge carrier's effective masses m* of the order of free electron mass
