HIFU: PROSPECTS OF APPLICATION IN ONCOUROLOGY
Description
Prostate cancer (PC) is one of the most frequently malignant neoplasms in the worldwide male population. Back in the 90's began a promising noninvasive method of high-intensity focused ultrasound (HIFU) as an alternative to radical prostatectomy for the treatment of localized prostate cancer was used. Information about the destructive histological effect by HIFU has been known since the 1930, however, the clinical implementation of this technology due to the absence at the time visualization capabilities for monitoring during the procedure has been postponed. In this paper, an overview of published data on the HIFU clinical application in prostate cancer as a major, "saving" and focal therapy. Examples of a favorable combination of this method are also provided with pharmacological agents. Based on the analysis of clinical data, we can say that HIFU is a good alternative minimally invasive therapeutic modality for patients with prostate cancer who are not candidates for radical prostatectomy. Applying of HIFU is possible as a treatment option with local recurrence after external radiotherapy, with careful selection of patients is important, depending on prognostic factors

Description
The article is devoted to the search and development of new models of structural changes. The results of these studies correct the activity of the major sugar integrated production systems of sugar subcomplex in the agro industrial subcomplex. The article reveals the problem of formation of an integrated methodology for analysis of structural changes in the economy of AIC, denoted with indicators and macroeconomic parameters of the sugar subcomplex, which need to be considered in the evaluation of structural changes. We set the task of developing a new tool of mathematical statistics, solving a range of problems for identifying non-stationary time series (NSTS) of the “beginning” of new super cycles (sets of cycles). In the economy the classic solution to this problem is in the field of detection of non-equilibrium effect of delayed reaction to earlier technological change, changes in foreign trade conditions, low mobility of labor and capital, and the various barriers to free competition. From our point of view, the ideal solution corresponds to the detection channel offset and the verification of dynamic series for homogeneity, i.e. the presence of phase transitions. The structural shift in the economy can be seen as a qualitative change in the system, consisting in the replacement of the previously existing ties between its constituent parts with new ones. Such shifts are due to the uneven development of the various elements of the economic system, they indicate that there are changes in the needs of subjects of economic life and economic resources. The author proposes a control parameter of the analysis, which uses methods to determine structural changes (tests Pettitte, Buishand and Alexandersson). The article deals with structural changes in the sugar industry of agriculture. The analyzed period is according to different categories from 60 to 180 years. The presence of structural changes is investigated by indicators such as the amount of sown areas, gross harvest, yield of sugar beet and sugar production from sugar beets and cane. We have investigated the theoretical and methodological approaches, the existing methods for the analysis of structural shifts in the economy and their impact on reproductive processes, their classification is given. We have identified key issues of improving efficiency and quality of transforming the economic structure of the sugar subcomplex. The article shows the dynamics of indicators of the economic structure of the sugar subcomplex of Russia and other countries of the world for different periods of time and its impact on sugar subcomplex of AIC. The author has proposed an adaptive algorithm and model test for homogeneity (structural shift) for integrated production systems that focus on sugar subcomplex of AIC. This method has been tested by the author in relation to economic systems (at various levels) of sugar subcomplex in agro industrial subcomplex of Russia, other countries and the world at large. Along with this, the author has proposed (we have developed a hierarchical analysis of structural changes) to use the identification of clusters for each category of sugar subcomplex with attraction of mathematical apparatus in the form of tests for homogeneity. We have marked indicators and parameters for the analysis of structural shift, the main reasons for this phenomenon. The results of empirical studies carried out have confirmed the possibility of practical use of the developed analysis

ANALYTICAL TOOLS OF VECTOR RISK ASSESSMENT OF THE FINANCIAL MARKET
Description
In rapidly changing conditions of the modern world, analysts and decision makers are in need to use new formal means of analysis and evaluation of alternatives problems. This work is dedicated to the development of such tools. The article presents a detailed analysis and technical and economic characteristics of the subject area - the financial market and its specific components - the value of a time series of gold, silver, palladium, platinum, and two kinds of exchange rates: EUR / RUB, USD / RUB. The authors have proposed a 5-criteria economic-mathematical model of the main components of the ranking of the financial market. The authors argue the impossibility of using a single integrated set of criteria for the replacement of the criteria or the use of criteria convolution procedures as the standard procedure of solving the problem of multi-criteria optimization. It demonstrates that such criteria as criteria for "risk" must be considered as an estimate of the degree of deviation from the expected value of the possible values of this criterion. The practical significance of the results is determined by the fact that the main points, conclusions, recommendations, models and methods can be used in order to improve the management and planning of development strategies of banking systems, trading platforms, as well as by developers of information and analytical systems to support management decisionmaking

Description
The article deals with methods of visual-graphic analysis (technical analysis) and a possibility of adapting them to the conditions (indicators) of the sugar subcomplex from the position of integrated production systems (IPS). It should be noted that technical analysis is very popular. Thanks to the advent of powerful processors for computers and inexpensive software, trade analysts have access to technical analysis tools. The topic is becoming increasingly relevant in connection with the high pace of the global economic community. Visual graphical analysis (technical analysis), as well as its latest methods (indicators) that are adapted to modern economic conditions, are sort of the primary "blueprints" for the more complex forecasting tools, without which none of the analyst can do. Separating statistics from mathematics as an independent unit occurred after the development and start of mass use of tools visual graphical analysis (VGA) in various applied Sciences. The main feature of the prediction is the decision of the tasks, which are implemented in the algorithm of sequential nonparametric model. This indicates the improving the validity of information when predicting performance of IPS SP AIC. For a more General (objective) picture of the forecasting activities of IPS SP you need to apply this analysis in combination with other tools, such as hierarchical analysis of structural change and of correlation and spectral analysis. According to the forecasts obtained with the help of the indicators VGA, countries such as Brazil and India over time, waiting for the "overheating" of the economy due to unprecedented growth in the volume of growing sugar cane and manufacturing raw sugar. However, it is not necessary to consider the visual-graphic analysis as a perfect tool for forecasting market trends. Technical analysis should be seen as a tool for analysis and forecasting, which uses as the basis for short-term forecasting (benchmark) for operational decision-making by managers as a major sugar holdings, and the Ministry of agriculture

06.00.00 Agricultural sciences
Description
The article contains research results on the influence of duration of the first lactation period of sows on reproductive qualities. The authors have detected basic problems which reduce indices reproduction of purebred pigs of the breed of Yorkshire and hybrids of F1 (Yorkshire x Landras) under conditions of a new complex. It was found that because of the increase in duration of lactation period of the sows it is impossible to increase the safety of the piglets with a reduced live mass (from big nests and slow in growth) and improve the reproductive quality of sows. This method has been used in the economy what led to a notable improvement in the indices of pig breeding

Description
This article is devoted to the asymptotic analysis of boundary value problem for a system of equations of Nernst-Planck and Poisson for a singularly perturbed system of ordinary differential equations [1], based on two parameters. This boundary value problem simulates electrodiffusion of four kinds of ions at the same time in the diffusion layer in electro-membrane systems with perfectly selective membrane, taling into consideration the reaction of recombination of two ions. Meanwhile the other two ions represent ions of a binary salt. As a simple example, we consider the transport of ions sodium, chlorine, hydrogen and hydroxide, moreover, hydrogen and hydroxyl ions recombine in the diffusion layer. A more complex case is the transfer of the products of dissociation of the dihydrogen phosphate of sodium, namely, ions of sodium and dihydrogen phosphate, the latter dissociate at the interface, in turn, hydrogen ions and hydrogen phosphate. Thus, in the solution can simultaneously store three different types of ions: sodium, hydrogen, phosphate. During the transfer, hydrogen ions and ions of hydrogen phosphate recombine to produce phosphoric acid. The article has revealed the structure of the Nernst diffusion layer at currents above Harkatsa current. It is shown, that in the diffusion layer, there are two types of boundary layers: the inner (reaction) boundary layer and boundary layer at the interface solution / membrane
