Abstract
The interaction of nutritional preservative and dye erythrosine B with bovine serum albumin (BSA) under the influence of millimeter range electromagnetic waves (MM EMW) with frequencies 41.8 and 51.8 GHz has been studied by the UV-denaturation and spectroscopic methods (absorption, fluorescence, and circular dichroism (CD)). We show that the irradiation by MM EMW with the frequency 51.8 GHz stabilizes the complex BSA-erythrosine B. At the same time, denaturation parameters of the complex at the irradiation of BSA solution with the frequency 41.8 GHz do not differ from those obtained for non-irradiated samples within the limits of experimental error. We also show that under the influence of the irradiation by 51.8 GHz frequency there is no conformational change of BSA. However, a change in the protein conformation takes place in the case of the complex BSA-erythrosine B. In addition, the complex-formation process is thermodynamically beneficial and implemented because of the additional hydrogen bonds and van-der-Waals interaction between BSA and erythrosine B under the influence of MM EMW.
摘要 在频率为 41.8 和 51.8 GHz 的毫米波电磁波(MM EMW)的影响下,通过紫外变性和光谱方法(吸收、荧光和圆二色性(CD))研究了营养防腐剂和染料赤藓红 B 与牛血清白蛋白(BSA)的相互作用。我们的研究结果表明,用频率为 51.8 GHz 的 MM EMW 对 BSA-erythrosine B 复合物进行辐照后,其变性参数在实验误差范围内与未辐照样品的变性参数没有差异。我们还发现,在 51.8 GHz 频率辐照的影响下,BSA 的构象没有发生变化。此外,在 MM EMW 的影响下,BSA 和赤藓红 B 之间产生了额外的氢键和范德华相互作用,因此复合体的形成过程在热力学上是有益的。

Abstract
Within the frameworks of the defect isotopic model, new expressions for the rapid estimation of the absorption coefficients of longitudinal and transverse hypersonic waves in the alloyed lithium niobate single crystals in the Akhiezer regime have been obtained. It is shown that the introduction of impurities in the crystal results in a change in both the magnitude of the sound attenuation coefficient and its temperature dependence.

Abstract
Vector non-stationary diffraction electromagnetic fields and fields of charges in an arbitrarily chosen volume in both homogeneous and inhomogeneous media are considered. These formulas are presented in two forms, each of which has its advantages in applications. The generalization of the Kirchhoff–Kottler vector formulas for discontinuous fields in the non-stationary case is also directly obtained.

Abstract
The electrically small phased antenna array is investigated. High permittivity dielectric and magnetodielectric materials (MDM) are used for antenna array substrates to miniaturize antenna size. To analyze material parameter influence on antenna performance, the same refractive index is considered for dielectric and MDM. The basic parameters of high permittivity-based, and MDM-based microstrip patch antenna arrays are compared. The simulation results show that the usage of MDM results in the improvement in bandwidth and isolation between elements, perfect impedance matching (voltage standing wave ratio (VSWR) < (~1.1) for center frequency) between material and free space over a much wider bandwidth.

Abstract
The magnetic size effects of single-domain nickel nanoparticles encapsulated in a graphite-like carbon shell (Ni@C nanocomposites) have been studied. Along with ferro- and superparamagnetic characteristics, the samples exhibit paramagnetism due to surface nickel ions formed through charge transfer from the carbon matrix. A detailed analysis of the total curves of magnetization M(H) and coercivity at 10 K was carried out and the corresponding magnetic parameters were determined.

Abstract
Single crystals of YAlO3-Er (YAP:Er) are grown by the Bridgman method from melts with different Y/Al ratio. The structural defects and color centers are compared for Y/Al = 1 and Y/Al > 1, as well as formed in the processes of gamma-irradiation and thermal treatment. Based on the obtained data, the growth conditions of YAP:Er crystals free of color centers and twins are determined. Spectral-luminescent properties of crystals are investigated: the absorption and luminescent spectra are registered in the polarized light, the luminescence kinetics is investigated and the lifetime of the 4I13/2 level of Er3+ ion is determined.

Abstract
We study an analytically solvable pseudoscalar interaction potential for the one-dimensional stationary Dirac equation, which consists of power terms proportional to ({{x}^{{ - 1}}}), ({{x}^{{ - 1/3}}}), and ({{x}^{{1/3}}}). This potential is classified as conditionally exactly solvable due to the fixed strength of the first term at a specific constant. We present the general solution to the Dirac equation in terms of non-integer index Hermite functions, which are distinct from the conventional integer index Hermite polynomials. We analyze the energy spectrum of the bound states and the eigenfunctions and compare the results with the case without the ({{x}^{{ - 1/3}}}) term.

Abstract
Within the framework of a three-dimensional model, the burnup process of the core of the WWER-440 reactor was studied using measurements of the operating cycles of the Armenian NPP (ANPP). Simulation results showed that a model study that takes into account only the temperature dependence of the thermal conductivity of the PATHS (PARCS Advanced Thermal Hydraulic Solver) fuel leads to discrepancies with the measured values of the boron concentration as the cycle time increases. However, taking into account the dependence of thermal conductivity on burnup significantly improved the agreement between the results of PARCS–PATHS (Purdue Advanced Reactor Core Simulator) and measurements. Taking into account the heat transfer of the fuel rod gap further improved the agreement between the simulation and measurement results. For the non-peripheral fuel assemblies, the relative difference between the predicted PARCS–PATHS and measured thermocouple results meet the acceptance criteria (≤10%). For peripheral assemblies that are in contact with the reflector by three faces, the relative error exceeds the acceptance criteria (15%) by 1–2%.
