TL;DR: In this paper, the influence of a random velocity field on the kinetics of the single-species annihilation reaction at and below its critical dimension d = 2 was studied using the Antonov-Kraichnan model, where the velocity field is modeled by a Gaussian variable self-similar in space with a finite-radius time correlation.
Abstract: Using the renormalization group in the perturbation theory, we study the influence of a random velocity field on the kinetics of the single-species annihilation reaction at and below its critical dimension d c = 2. The advecting velocity field is modeled by a Gaussian variable self-similar in space with a finite-radius time correlation (the Antonov-Kraichnan model). We take the effect of the compressibility of the velocity field into account and analyze the model near its critical dimension using a three-parameter expansion in ∈, Δ, and η, where ∈ is the deviation from the Kolmogorov scaling, Δ is the deviation from the (critical) space dimension two, and η is the deviation from the parabolic dispersion law. Depending on the values of these exponents and the compressiblity parameter α, the studied model can exhibit various asymptotic (long-time) regimes corresponding to infrared fixed points of the renormalization group. We summarize the possible regimes and calculate the decay rates for the mean particle number in the leading order of the perturbation theory.

TL;DR: In this paper, the authors analyzed the possible causes and consequences of the alleged semantic redundancy of the term "hybrid war/warfare" and concluded that the term works in favour of the empowering of the "fog of war".
Abstract: The article analyses the genesis, semantical shifts and contemporary role of the term “hybrid war/warfare” in the cognitive domain. The main aim of the article is to define the possible causes and consequences of the alleged semantic redundancy of the term “hybrid war/warfare”. As the result of the analysis, it was concluded how the term “hybrid war/warfare” works in favour of the empowering of the “fog of war”: it substitutes the concept of the conventional war, which is commonly obvious, and directs public attention towards the semantic fuzziness, which implicitly eliminates the essential features of the conventional armed conflict. This creates a cognitive bias, which still does not seem properly analysed and understood.

TL;DR: In this paper, the authors discuss the role of state finance control in the preditictions of financing of terrorism in the 21st century and show how terrorist organizations are adapting to the current situation and finding new methods and ways of meeting their specific goals with the use of different sources of funding, and what the methods of counteracting them in international practice and in Ukraine.
Abstract: As the title implies the article describes essential world problem – financing of terrorism. It is specially noted the role state finance control in the preditictions of financing of terrorism. During the 21st century the topic of terrorism has become one of the most dangerous and large-scale global challenges to the world community. Since the events of September 11, 2001 in the United States of America, the phenomenon of terrorism has become more violent, bloody and cynical. The number of states that have experienced the horrific consequences of acts of terrorism is on the rise, and in turn, bears human toll, destruction of infrastructure, intimidation of people and more. The article shows how terrorist organizations are adapting to the current situation and finding new methods and ways of meeting their specific goals with the use of different sources of funding, and what the methods of counteracting them in international practice and in Ukraine. Also, It draws our attention to to analyze the notion of terrorist financing and international experience in opposing it. Much attention is given to analyze the manifestations of terrorist financing in Ukraine.

TL;DR: A new AVO inversion method for seismic data processing is introduced, showing that five attributes are sensitive to the geophysical characteristics of gas hydrate reservoir and its boundary, such as intercept, Poisson ratio, fluid factor, product of gradient with intercept and relative coefficient.
Abstract: This paper introduced a new AVO inversion method for seismic data processing. By introducing the relation between the variation of pre-stack seismic response amplitude versus incident angle and formation elastic parameter, the rock's elastic parameters as density, P-wave velocity, S-wave velocity and Poisson ratio are obtained through mathematical calculation and can be further used in lithology analysis and detection of gas hydrate. The experiments shows that five attributes are sensitive to the geophysical characteristics of gas hydrate reservoir and its boundary, such as intercept, Poisson ratio, fluid factor, product of gradient with intercept and relative coefficient, product of gradient with symbol of intercept. The first sample of gas hydrate acquired in the survey affirmed the feasibility and applicability of AVO inversion in gas hydrate exploration.
