OSINT as a part of cyber defense system

The paper presents the results of research on the development of fundamental and applied principles for analyzing information flows in global computer networks while conducting open source intelligence (OSINT). The relevance of this task, in particular, concerning the provision of cyber security, the parameters of the modern information space, the existing theoretical and technological solutions are substantiated. The description of methodological and instrumental means of analysis and modeling of information flows, distributed content monitoring of global networks, the creation of multilingual full-text databases, analysis of the dynamics of thematic information flows with the use of nonlinear analysis, automatic formation of models of subject areas in the field of cyber security are presented

Calculation of The Band Gap Energy and Study of Cross Luminescence in Alkaline-Earth Dihalide Crystals

The band gap energy as well as the possibility of cross luminescence processes in alkaline-earth dihalide crystals have been calculated using the ab initio Perturbed-Ion (PI) model. The gap is calculated in several ways: as a difference between one-electron energy eigenvalues and as a difference between total energies of appropriate electronic states of the crystal, both at the HF level and with inclusion of Coulomb correlation effects. In order to study the possibility of ocurrence of cross luminescence in these materials, the energy difference between the valence band and the upmost core band for some representative crystals has been calculated. Both calculated band gap energies and cross luminescence predictions compare very well with the available experimental results.Comment: LaTeX file containing 8 pages plus 1 postscript figure.

НЕКОНЪЮГИРОВАННАЯ ГИПЕРБИЛИРУБИНЕМИЯ У БОЛЬНЫХ СИНДРОМОМ КОМПРЕССИИ ЧРЕВНОГО СТВОЛА

The level of the total, conjugated and unconjugated bilirubin has been assessed after celiac trunk decompression in 621 patients with celiac trunk compression syndrome. Relatively mild, mainly unconjugated hyperbilirubinemia has been found in 23.4 % of the young patients predominantly. The main values of the celiac trunk duplex scanning have been hemodynamically significant. Normalization of bilirubin and its fractions values was seen in most of the patients in the early postoperative course after surgical celiac trunk decompression. The results show the effect of the celiac trunk stenosis and decrease in the liver blood flow on the possible development of unconjugated hyperbilirubinemia in the patients with this artery compression syndrome.Исследован уровень общего, конъюгированного и неконъюгированного билирубина у 621 больного синдромом компрессии чревного ствола, которым была выполнена его декомпрессия. У 23,4 % была обнаружена относительно небольшая гипербилирубинемия, в основном неконъюгированная, преимущественно у молодых пациентов. Основные показатели дуплексного сканирования чревного ствола были гемодинамически значимыми. После хирургической декомпрессии чревного ствола у большинства больных в раннем послеоперационном периоде наступила нормализация показателей билирубина и его фракций. Результаты показывают влияние стеноза чревного ствола и снижения печеночного кровотока на возможное развитие неконъюгированной гипербилирубинемии у больных синдромом компрессии этой артерии

Interactions between the atmosphere, cryosphere, and ecosystems at northern high latitudes

The Nordic Centre of Excellence CRAICC (Cryosphere–Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011–2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research and innovation regarding climate change issues in the Nordic region. CRAICC gathered more than 100 scientists from all Nordic countries in a virtual centre with the objectives of identifying and quantifying the major processes controlling Arctic warming and related feedback mechanisms, outlining strategies to mitigate Arctic warming, and developing Nordic Earth system modelling with a focus on short-lived climate forcers (SLCFs), including natural and anthropogenic aerosols. The outcome of CRAICC is reflected in more than 150 peer-reviewed scientific publications, most of which are in the CRAICC special issue of the journal Atmospheric Chemistry and Physics. This paper presents an overview of the main scientific topics investigated in the centre and provides the reader with a state-of-the-art comprehensive summary of what has been achieved in CRAICC with links to the particular publications for further detail. Faced with a vast amount of scientific discovery, we do not claim to completely summarize the results from CRAICC within this paper, but rather concentrate here on the main results which are related to feedback loops in climate change–cryosphere interactions that affect Arctic amplification.</p

The Current State of Public Finances in Ukraine: Priorities, Strategy and Risks

The aim of the article is to study the current state of public finances in Ukraine, define the problems hindering the stabilization of the macroeconomic situation in the country and elaborate strategies for achieving the economic development by determining its three components. The current macroeconomic situation in the country is analyzed; the basic indicators of sustainability of public finances are determined. It has been found that the low level of economic development in the coming years will be the key factor weakening the sustainability of public finances in the country. In this regard recommendations on the ways of reforming the system of public finances are given. There justified concrete measures on their implementation taking into account the actualization of the new challenges that have arisen before Ukraine. In the course of the study there proved the relevance of the system transformations in the fiscal and monetary policy of the government; the need to modernize production facilities and introduce new technologies, the increase of investments in innovations at the micro level in order to restore the national economy, which in the future will increase the possibilities of the budget and allow the country to repay debt
