Starovoitova O. V., Tukalenko O. N. Investigation of fluctuation characteristics in autogenerators on different transistors
A study of the characteristics of high-frequency oscillators on different transistors. The influence of transistor noise on fluctuations is considered. It is noted that in generators with a smaller nonisochronicity and with smaller cut-off angles of the current of the transistor, the fluctuations of self-oscillations are significantly lower. Formulated recommendations on the ...
On interaction of a qubit with a fluctuating environment
It is shown that the equations of Gurvitz and Mozyrsky for a system consisting of a qubit interacting with a fluctuating environment in certain conditions are reduced to evolution equations of the qubit. Such evolution equations for the qubit can be generalized to the form, which implies the existence of entangled states of the combined system. Among these entangled ...
The use of the fluctuating asymmetry coefficient as a quality assessment criteria for morphometric adaptation of wood vegetation to technogenic conditions
The article is focused on the development of a methodology for quantitative assessment of adaptive changes magnitude in woody vegetation in the vicinity of the Gomel Polissyе major industrial enterprises on the basis the of leaf blades fluctuating asymmetry index. This justifies the possibility of using this value as a criterion for assessing the woody vegetation adaptation at the morphometric level and further production under technogenic environmental impact.

The role of endogenous factor in increase of ocean level for the last 140 years
... examines the structure and dynamics of the World Ocean level during the past 140 years. The role of endogenous factor
in constant increase of water supply and subsequent rise of the sea level is defined as dominating. Two principle cycles in the sea level fluctuations were distinguished: a high-amplitude short-term cycle (2—3 years) and a low-amplitude long-term one (40—50 years). The concurrency of two events is traced: short-term cycles and major earthquakes in oceanic regions. It was shown that ...

Factors and risks of modern ecionomic dynamics: post-crisis tendencies in Russia
Russian economy is overcoming the crisis; its further restoration and growth depend on different factors: abrupt and not always predictable changes in the world economic situation, dynamics and fluctuations of oil prices, inflow and outflow of capital from financial markets, and other external economic and political factors. However, there is increasing awareness that the restoration and growth largely depend on internal fundamental factors: ...

The thinking of nature and the nature of thinking — Cohen on Spinoza
The author tries to prove the thesis that Cohen's reception of Spinoza's thought is character-ized by a sequence of what we can find in the whole philosophical system of Marburg Neo-Kantian. Fluctuations in Cohen's interpretation of Spinoza's theoretical constructs correspond to a progres-sive refinement of his own philosophical system project. This research does not aim to shed new light on the wide panorama presented approaches and points ...
