Features of Magneto-Optical Resonances in an Elliptically Polarized Traveling Light Wave
The parameters of nonlinear absorption magneto-optical resonances in the
Hanle configuration have been studied as functions of the ellipticity of a
traveling light wave. It has been found that these parameters (amplitude,
width, and amplitude-to-width ratio) depend strongly on the polarization of the
light wave. In particular, the resonance amplitude can increase by more than an
order of magnitude when the polarization changes from linear to optimal
elliptic. It has been shown that this effect is associated with the Doppler
frequency shift for atoms in a gas. The theoretical results have been
corroborated in experiments in Rb vapor.Comment: 5 page
Distinguishing Lewd and Lascivious Acts from Related Crimes Against Minors’ Sexual Immunity
The article deals with the criminal law norms related to the crime provided for by Article 135 of the Criminal Code of the Russian Federation. The authors estimate judicial practice and outline disputable issues of correlation of the given norms and offer the criteria to distinguish lewd and lascivious acts from related crimes
Capillary wave turbulence on a spherical fluid surface in low gravity
We report the observation of capillary wave turbulence on the surface of a
fluid layer in a low-gravity environment. In such conditions, the fluid covers
all the internal surface of the spherical container which is submitted to
random forcing. The surface wave amplitude displays power-law spectrum over two
decades in frequency, corresponding to wavelength from to a few . This
spectrum is found in roughly good agreement with wave turbulence theory. Such a
large scale observation without gravity waves has never been reached during
ground experiments. When the forcing is periodic, two-dimensional spherical
patterns are observed on the fluid surface such as subharmonic stripes or
hexagons with wavelength satisfying the capillary wave dispersion relation
System development of estimated figures of volume production plan
The relevance of this problem is primarily determined by a necessity of improving production efficiency in conditions of innovative development of the economy and implementation of Import Substitution Program. The purpose of the article is development of set of criteria and procedures for the comparative assessment of alternative volume production plans and choice of optimum alternative. The leading method of the study of the problem is economic-mathematical modeling, providing the variability of volume plan development on the basis of different factors and variables, which reflect actual operating standards of a particular study subject. The results of the study: In the article, economic-mathematical model for development of aggregate production plan was presented, on the basis of which alternatives was produced, estimated figures, characterizing efficiency of derived alternatives, were justified, the key factors, which determine a specific set of variables and constraints, were considered. The article materials can be useful for experts, which are specialized in planning of production and distribution of the production program in choosing optimum alternative of aggregate production plan. © 2016 Brazhnikov et al
Weak Turbulent Kolmogorov Spectrum for Surface Gravity Waves
We study the long-time evolution of gravity waves on deep water exited by the
stochastic external force concentrated in moderately small wave numbers. We
numerically implement the primitive Euler equations for the potential flow of
an ideal fluid with free surface written in canonical variables, using
expansion of the Hamiltonian in powers of nonlinearity of up to fourth order
terms.
We show that due to nonlinear interaction processes a stationary energy
spectrum close to is formed. The observed spectrum can be
interpreted as a weak-turbulent Kolmogorov spectrum for a direct cascade of
energy.Comment: 4 pages, 5 figure
