В статье анализируются новостные сообщения американского медиадискурса, связанные с вакцинами от коронавируса, произведенные в России и Китае. ; This technique has been tested on the material of the American media discourse, namely many news reports published in the USA press and devoted to news related to coronavirus vaccines produced in Russia and China.

В статье рассматриваются этапы становления и развития военного дискурса в Китае. ; The article presents an overview of military discourse studies and related notions in China over the last three decades. The author singles out and characterizes the stages of emergence and development of this research area and notes the tendency to activate these studies and to expand the scope of their objects and methods. Interest in this research area is associated with the modification of conflicts in the modern world: their participants use super modern technical means that allow waging information and commercial warfare on the global scale.

The article is devoted to the development of traditional Chinese medicine in modern China as one of the main directions of culture. The author examines the formation of the modern status of traditional medicine, its popularity, effectiveness in the fight against coronavirus. Much attention in this article is also paid to the creation of such a scientific discipline as the discourse of traditional medicine, within which terminological bases should be systematized, as well as a system for teaching Chinese medicine in foreign languages, in particular in Russian, should be formed.

This report presents an accelerated kinetic Monte Carlo (KMC) method to compute the diffusivity of hydrogen in hcp metals and alloys, considering both thermally activated hopping and quantum tunneling. The acceleration is achieved by replacing regular KMC jumps in trapping energy basins formed by neighboring tetrahedral interstitial sites, with analytical solutions for basin exiting time and probability. Parameterized by density functional theory (DFT) calculations, the accelerated KMC method is shown to be capable of efficiently calculating hydrogen diffusivity in alpha-Zr and Zircaloy, without altering the kinetics of long-range diffusion. Above room temperature, hydrogen diffusion in alpha-Zr and Zircaloy is dominated by thermal hopping, with negligible contribution from quantum tunneling. The diffusivity predicted by this DFT + KMC approach agrees well with that from previous independent experiments and theories, without using any data fitting. The diffusivity along is found to be slightly higher than that along , with the anisotropy saturated at about 1.20 at high temperatures, resolving contradictory results in previous experiments. Demonstrated using hydrogen diffusion in alpha-Zr, the same method can be extended for on-lattice diffusion in hcp metals, or systems with similar trapping basins. ; INL Laboratory Directed Research and Development Program [14-026]; Department of Energy (DOE) Nuclear Energy Advanced Modeling and Simulation (NEAMS) program; U.S. Department of Energy [DE-AC07-05ID14517] ; The INL authors gratefully acknowledge the support of the INL Laboratory Directed Research and Development Program under project #14-026, "Multiscale modeling on delayed hydride cracking in zirconium: hydrogen transport and hydride nucleation", and the Department of Energy (DOE) Nuclear Energy Advanced Modeling and Simulation (NEAMS) program.

AbstractDetermining the hedge ratio based on the slope coefficient of a regression on price changes suffers from several critical shortcomings. First, it is difficult to assemble a properly constructed data set. Second, results vary depending on the length of the change interval. Third, the resulting ex post effective prices realized under this approach are wholly uncertain, ex ante. We show that when the hedge ratio is determined with reference to a regression on the respective price levels, rather than price changes, the resulting hedge ratio solution is superior in that none of these shortcomings apply.
