Synergetic method of a quantitative forecasting of economic times series
In the article, a synergetic method of the economic time series forecasting on the basis of the modified
method of Hurst is discussed. It is a new nonlinear method of predicting the development of economic systems
according to time series on macro- and mesolevels. The main theorem underlying the forecasting method is
formulated and strictly proved: for a chaotic series of a particular length it is possible to specify a time interval
where the series is reliably predicted with the Hurst exponent more than 0.5. The examples of the fractal
characteristics’ calculation and the forecasting taking into account time of reliable forecast of the socioeconomic
indexes’ behavior — oil prices, natural gas prices, the Dow Jones index, the «euro-dollar» prices, the
Gross Domestic Product, and some other indicators at the regional level are given. All calculations are carried
out by means of the specialized software product upgraded for the task solution set in this article
Bioinert Properties of a Coronary Stent with Nanostructural Carbon Coating
ABSTRACT The article is dedicated to study of bioinert properties of a coronary stent with nanostructural carbon coating by the up-to-date methods of intravascular visualization. It was evidenced that use of a stent with nanostructural carbon coating results in reduction of the risk of in-stent stenosis by more then 2 times as compared to endoprostheses made of stainless steel without surface modification and does not induce thrombogenesis when standard antiaggregant doses are used
