On the basis of conditionally-periodic solutions of Hamiltonian systems at resonance of main frequencies Cassini’s motions, their stability, Cassini’s angle and periods of free librations of the Moon and Mercury have been recently studied and determined. The generalized formulations of Cassini’s laws for the motion of the Moon and Mercury, that are considered as absolutely rigid non-spherical bodies, have been determined. The study of the second approximation equations of the desired quasi-periodic solutions in the case of the Moon allows us to determine the constant components of the first order for six Andoyer variables and the constant component of the second order for the angular velocity of the Moon. These effects are caused by the influence of the third harmonic of selenopotential. In this paper, these effects are described by analytical formulas, the dynamic and geometric interpretations are given, and a new interpretation of Mercury’s motion under the generalized Cassini’s laws has been proposed. Predictions of the existence of free librations of significant amplitude in the Mercury longitude, that are confirmed by the radar measurements data of the Mercury angular velocity, and in its pole motion in the body and in space have been made. The mechanism describing free librations of celestial bodies and their pole oscillations has been proposed due to the forced relative oscillations and wobble of the core-mantle system of celestial bodies（Moon, Mercury, Earth and other bodies in the solar system） under gravitational action of the external celestial bodies. The paper shows that the ascending node of equator of Mercury（and the intermediate plane orthogonal to the angular momentum） of epoch 2000.0 on the ecliptic does not coincide with the ascending node of orbital plane of Mercury on the same plane, and is ahead of it at an angle 23°4’. Angular momentum vector of the rotational motion of Mercury forms a constant angle p;=4’1±1’1 with normal to the moveable plan

Due to a paucity of surveys in northern Indochina and lack of international collaborations among neighboring countries, recognized distributional ranges for many amphibian and reptile species end at the political borders for some countries, despite seemingly continuous suitable habitat spanning the region. Combining both morphological and genetic data, we report the first discovery of Japalura chapaensis, a rare agamid lizard believed previously to be endemic to northern Vietnam only, along the border region of southeastern Yunnan Province,China. To facilitate future research on the genus Japalura sensu lato in Indochina, we provide detailed descriptions of additional specimens of this rare species, including the first description of coloration in life and an expanded diagnosis, and discuss the species boundary of J. chapaensis with respect to its congeners.

The paper presents the basic principles of the information image theory and a mathematical model developed using it. The hierarchy of information images in an individual mind, which determines his∖her real and virtual activity, is considered. Algorithms for describing transfer and distortion of information images by individuals in the communication process are constructed. To corroborate the theory experimentally, the bilingual Stroop test is used. The results of the test are interpreted using the introduced theory, and are then compared with the results of computer modeling based on the theory. It is shown that information images can be used not only to explain a number of cognitive processes of the human mind, but also to predict their dynamics in a number of particular cases.

X-ray absorption spectroscopy is proposed as a method for studying the heating of solid-density matter excited by secondary X-ray radiation from a relativistic laser-produced plasma. The method was developed and applied to experiments involving thin silicon foils irradiated by 0.5–1.5 ps duration ultrahigh contrast laser pulses at intensities between 0.5 × 10^(20) and 2.5 × 10^(20) W∕cm^2. The electron temperature of the material at the rear side of the target is estimated to be in the range of 140–300 eV. The diagnostic approach enables the study of warm dense matter states with low self-emissivity.
