This article is dedicated to the publication and the comparative analysis of 11 – 12 centuries Pereiaslavl (modern name Pereiaslav) cranial series found during excavations by D. Samokvasov (1877), V. Shcherbakivskyi (1914), and a permanent archaeological expedition of the National Historical and Ethnographic Reserve «Pereyaslav» under the leadership of M. Tovkailo (2004 – 2007), D. Teteria (2008 – 2012), M. Rozdobudko (2014 – 2016), O. Priadko (2015 – 2019). The purpose of the article is to introduce a new material into scientific domain, provide a general description of Pereiaslav population of 11th – 12th cent. on the background of neighboring ethnic groups from Ukraine and Eastern Europe (synchronistic method), determine the distance between separate cranial series of 11th – 12th cent. with the help of multidimensional canonical and cluster analysis, and to find out the place of 11th – 12th cent. Pereiaslav male population in the system of craniological types of Eastern Europe. This paper attempts to apply two typological approaches to the researched group. The methodology of the research. The research is based on the principles of historicism and objectivity, general scientific (analysis and synthesis), historical (comparative-historical), anthropological and statistical methods were used. The skulls were measured according to the full craniometric program using the standard R. Martin method, according to which the numbering of signs was indicated. Computer software developed by B. Kozintsev and O. Kozintsev in 1991 has been used in the research. 14 craniometric traits defined by R. Martin have been involved into the study. Scientific novelty of the work is that for the first time, the general male Old Rus selection of Pereiaslav town including 59 skulls has been created. According to the craniometric trait average value, the male part of the series can be classified as dolichocranic Caucasoid variant with moderately broad face. It has been proved that after uniting two male craniological groups from Pereiaslav, its representatives, according to typological scheme by T. Alekseeva, belong to dolichocranic, middle size face craniological type. This is the same type where Siverians, Dregoviches, Smolensk Krivichs, and Radimichs belong to. Grounding on V. Diachenko typology, the male group can be classified to some extend as Neopontic craniological type. Conclusion. The comparison of the male researched group from 11th – 12th cent. with synchronic series from Old Rus territory with the help of multidimensional canonical and cluster analysis has shown its similarity to town series from Liubech, Halych and to less extend Chernihiv.

The electronic nose system is widely used in tea aroma detecting, and the sensor array plays a fundamental role for obtaining good results. Here, a sensor array optimization (SAO) method based on correlation coefficient and cluster analysis (CA) is proposed. First, correlation coefficient and distinguishing performance value (DPV) are calculated to eliminate redundant sensors. Then, the sensor independence is obtained through cluster analysis and the number of sensors is confirmed. Finally, the optimized sensor array is constructed. According to the results of the proposed method, sensor array for green tea (LG), fried green tea (LF) and baked green tea (LB) are constructed, and validation experiments are carried out. The classification accuracy using methods of linear discriminant analysis (LDA) based on the average value (LDA-ave) combined with nearest-neighbor classifier (NNC) can almost reach 94.44~100%. When the proposed method is used to discriminate between various grades of West Lake Longjing tea, LF can show comparable performance to that of the German PEN2 electronic nose. The electronic nose SAO method proposed in this paper can effectively eliminate redundant sensors and improve the quality of original tea aroma data. With fewer sensors, the optimized sensor array contributes to the miniaturization and cost reduction of the electronic nose system.

Subject. The article focuses on the modern financial system of Russia. Objectives. I determine the limit of the contemporary financial system in Russia. Methods. The study is based on methods of descriptive statistics, statistical and cluster analysis. Results. The article shows the possibility of determining the scope of the contemporary financial system in Russia by establishing monetary relations as the order of the internal system and concerted operation of subsystems, preserving the structure of the financial system, maintaining the operational regime, implementing the program and achieving the goal. I found that the Russian financial system correlated with the Angolan one, and the real scope of the contemporary financial system in Russia. Conclusions and Relevance. As an attempt to effectively establish monetary relations and manage them, the limit of the contemporary financial system is related to the possibility of using Monetary Aggregate M0 to maintain the balance of the Central Bank of Russia. To overcome the scope of Russia’s financial system, the economy should have changed its specialization, refocusing it on high-tech export and increasing the foreign currency reserves. This can be done if amendments to Russia’s Constitution are adopted. The findings expand the scope of knowledge and create new competence in the establishment of monetary relations, order of the internal system and concerted interaction of subsystems, structural preservation of the financial system and maintenance of its operational regime.

AbstractEndometriosis is an inflammatory disease which diagnostics is difficult and often invasive, therefore non-invasive diagnostics methods and parameters are needed for endometriosis detection. The aim of our study was to analyse the glycosylation of native serum IgG and IgG isolated from sera of women classified as: with endometriosis, without endometriosis but with some benign ginecological disease, and control group of healthy women, in context of its utility for differentiation of advanced endometriosis from the group of healthy women. IgG sialylation and galactosylation/agalactosylation degree was determined using specific lectins: MAA and SNA detecting sialic acid α2,3- and α2,6-linked, respectively, RCA-I and GSL-II specific to terminal Gal and terminal GlcNAc, respectively. The results of ROC and cluster analysis showed that the serum IgG MAA-reactivity, sialylation and agalactosylation factor may be used as supplementary parameters for endometriosis diagnostics and could be taken into account as a useful clinical tool to elucidate women with high risk of endometriosis development. Additionally, we have shown that the analysis of native serum IgG glycosylation, without the prior time-consuming and expensive isolation of the protein, is sufficient to differentiation endometriosis from a group of healthy women.
