Аннотация: The distribution of triplets alongside a genome is studied.We explored the distribution to the nearest neighbour, that is the pattern where two triplets are fixed, and the distance is determined from the former to the latter so that the second triplet takes place nowhere inside the observed gap surrounded with the couple of the given triplets. The distribution differs strongly, for different organisms. Yeast and bacteria seem to have rather smooth pattern, while mammalia and other higher eukaryotes exhibit very complex patterns with long-range correlations in the triplet distribution. © Springer International Publishing Switzerland 2015.

Аннотация: A salt stratified Lake Shira has been the subject of extensive research because of its central role in the existence of the Khakassia resort area. The previous research was mainly aimed at water quality issues. The studies of the physical dynamics of Lake Shira relevant to the present work include the general observation of currents on the basis of the field experiments in 2011-2014. Velocity measurements were carried out using Doppler Current Profilers with frequency 600 kHz and 1200 kHz in the bottom track mode in 2012 and at several permanent stations in other years. Temperature measurements were performed using distributed temperature sensors at several stations. In the field observations, internal waves were detected. Three-dimensional primitive equation numerical model GETM is applied to simulate hydrophysical processes in Lake Shira. The model is hydrostatic and Boussinesq. The measured temperature and salinity distribution is taken as the initial data for computations. Computations with time constant wind and the initial horizontally homogeneous and vertically stratified density illustrate the dependence of three dimensional current on the wind strength and direction. The calculations with the variable wind speed show that the termination of the wind leads to the appearance of the internal waves. © SGEM2018 All Rights Reserved.

Аннотация: Planet atmospheric escape induced by high-energy stellar irradiation is a key phenomenon shaping the structure and evolution of planetary atmospheres. Therefore, the present-day properties of a planetary atmosphere are intimately connected with the amount of stellar flux received by a planet during its lifetime, thus with the evolutionary path of its host star. Using a recently developed analytic approximation based on hydrodynamic simulations for atmospheric escape rates, we track within a Bayesian framework the evolution of a planet as a function of stellar flux evolution history, constrained by the measured planetary radius. We find that the ideal objects for this type of study are close-in sub-Neptune-like planets, as they are highly affected by atmospheric escape, and yet retain a significant fraction of their primordial hydrogen-dominated atmospheres. Furthermore, we apply this analysis to the HD 3167 and K2-32 planetary systems. For HD 3167, we find that the most probable irradiation level at 150 Myr was between 40 and 130 times solar, corresponding to a rotation period of 1.78(-1.23)(+2.69) days. For K2-32, we find a surprisingly low irradiation level ranging between half and four times solar at 150 Myr. Finally, we show that for multi-planet systems, our framework enables one to constrain poorly known properties of individual planets.

Аннотация: A probabilistic numerical model for fracture of unidirectional composite materials is developed. The algorithm for numerical simulation of the model takes into account the random distribution of carbon fibers, the spread of mechanical properties and the fracture of the structural elements of the material. Multivariate numerical experiments of the composite material of a composite overwrapped pressure vessel under tensile loads were carried out. The analysis of the patterns of deformation and fracture of a composite material is carried out. The physical mechanism of deformation and fracture of a composite material corresponds to a numerical model. The stress-strain curves of a numerical model of a composite material at 70% carbon fiber content are presented. The calculated values of Young's modulus and tensile strength of the composite material at different percentages are obtained. A comparative analysis of experimental and numerical results showed that the results corresponded to 15%. Using of a numerical model of deformation and fracture of unidirectional composite materials makes it possible to track the mechanics of the processes of fracture of fibers and matrix, to obtain the most accurate analysis of the stress-strain state, and to develop generalized methods for calculating the strength of composite overwrapped pressure vessels © Published under licence by IOP Publishing Ltd.
