TL;DR: In this article, the authors studied magnetic and electric dipole excitations in the energy interval 20-40MeV for the even-even 124-136Ba isotopes within the rotational, translational and Galilean invariant Quasiparticle Random Phase Approximation (QRPA) and showed that low-lying magnetic and electrical dipole states have mainly a Delta K=1 character.
Abstract: Magnetic and electric dipole excitations in the energy interval 20-40MeV are studied for the even-even 124-136Ba isotopes within the rotational, translational and Galilean invariant Quasiparticle Random Phase Approximation (QRPA) The calculations show that low-lying magnetic and electric dipole states have mainly \( \Delta K=1\) character Systematical analysis of the summed excitation strengths of the scissors mode as a function of deformation parameters or the mass number A was also done It is shown that in the even-even 124-136Ba isotopes, the dependence of the total B(M1) transition on \( \delta_{2}^{2}\) is nearly linear for the well-deformed isotopes The agreement between the calculated excitation energies as well as the summed B(M1) values of the scissors mode and the available experimental data is quite good In addition, we predicted E1 dipole excitations for the even-even 124-136Ba isotopes which have not been observed experimentally, yet

TL;DR: In this article, the thermal oxidative decomposition of benzotriazolyl-substituted phthalocyanines and their copper complexes is investigated by means of thermogravimetric, elemental, and spectroscopic analysis.
Abstract: The thermal oxidative decomposition of benzotriazolyl-substituted phthalocyanines and their copper complexes is investigated by means of thermogravimetric, elemental, and spectroscopic analysis. It is shown that the nature of peripheral substituents exerts the greatest effect on the thermal stability of the compounds.

TL;DR: In this paper, the authors proposed a high-speed optical sensor based on micron-size ring resonators consisting of waveguides with one or several slots with a liquid crystal filling.
Abstract: Methods of constructing and the operating principles of a high-speed optical sensor for highly accurate measurements of small temperature variations are considered.

TL;DR: In this paper, the structural phase states of surface layers of titanium alloyed with nickel are studied after impact of plasma compression flows (CPF) on titanium previously coated with nickel, and it is shown that the modified surface layer is characterized by a fairly low modulus of elasticity (48 GPa).
Abstract: Structural-phase states of surface layers of titanium alloyed with nickel are studied after impact of plasma compression flows (CPF) on titanium previously coated with nickel. It is shown that, at the thickness of nickel coating of 3–6 μm, action of CPF with energy density in the range from 9 to 23 J/cm2 provides formation of a surface layer containing titanium nickelide TiNi, Ti2Ni, and a solid solution based on high-temperature titanium phase β-Ti(Ni). It is found that the modified surface layer is characterized by a fairly low modulus of elasticity (48 GPa), which makes possible its usage as a biocompatible material.

TL;DR: In this paper, the effect of various process parameters on the wear of surface layer of machine parts was studied using second-order orthogonal planning, and the mechanisms of the surface layer formation as a function of process factors were discussed.
Abstract: The effect of various process parameters on the wear of surface layer of machine parts is studied using second-order orthogonal planning. Models characterizing the effect of process parameters on the wear of parts were obtained by calculation. The mechanisms of surface layer formation as a function of process factors are discussed.

TL;DR: In this article, two nonparametric methods are discussed for identification of anomalies in multidimensional hydrogeochemical data with the goal of forecasting major seismic events, based on using the threshold copula function aimed at the definition of change moments in the structure of dependencies between the components of a multi-dimensional vector of observations.
Abstract: We consider two nonparametric methods are discussed for identification of anomalies in multidimensional hydrogeochemical data with the goal of forecasting major seismic events. The first method is based on using the threshold copula function aimed at the definition of change moments in the structure of dependencies between the components of a multidimensional vector of observations. The second method is designed to transform multidimensional data to one-dimensional which allows to use rank score tests.
