it was pointed out that for thermal hydrodynamic (cid:29)uctuations in open hydrodynamic steady states (OHSS) the determining factor for derivation of reciprocal relations is not the principle of microscopic reversibility, but the presence or absence of a (cid:29)ux. In the present work this idea is applied to open chemical steady states (OCSS), where chemical oscillations are possible. The behavior of concentration (cid:29)uctuations when there are no macroscopic oscillations yet is considered. The reciprocal relations for such OCSS are found.

The necessary conditions are established for the thicknesses of two layers of the planar absorbing structure at which zero re(cid:29)ectance can be achieved. Using these conditions, a numerical procedure was developed for (cid:28)nding the thicknesses of three layers of the structure, which makes it possible to achieve close to zero values of the re(cid:29)ectance and transmittance for the chosen wavelength. This made it possible to propose a method for designing narrow-band absorbers based on such structures.

The Closed Cluster method (CC method) is applied to find solutions for various calculation problems of the energy band structure of graphene. The essence of the CC method consists in the addition of closing bonds between edge atoms to the usual cluster method in order to eliminate the dangling bonds on the edges of the cluster. We study the cases of an infinite layer of graphene as well as nanoribbons, nanotubes and bilayer graphene. Results for these cases are in agreement to that what was obtained by means of other methods (tight binding approximation and others). By means of the CC method we also study the problem of point defects in graphene and obtain the distortion of the energy spectrum. The energy spectrum of the layer C$_{1-x}$ Si$_{x}$ $(0leq x leq 1)$ is found as well as the dependence of the energy gap on the concentration of silicon. We show that the energy band structure of C$_{1-x}$ Si$_{x}$ looks like a tunnel transition. Wave functions of graphene in the symmetry points of Brillouin zone are also obtained.
采用闭簇法求解石墨烯能带结构的各种计算问题。CC方法的实质在于在常规簇法的基础上增加了边缘原子间的闭合键，以消除簇边的悬空键。我们研究了无限层石墨烯以及纳米带、纳米管和双层石墨烯的情况。这些情况的结果与用其他方法(紧密结合近似等)得到的结果一致。利用CC方法研究了石墨烯的点缺陷问题，得到了其能谱的畸变。得到了C层$_{1-x}$ Si $_{x}$$(0leq x leq 1)$的能谱以及能隙与硅浓度的关系。我们发现C $_{1-x}$ Si $_{x}$的能带结构看起来像一个隧道跃迁。得到了石墨烯在布里渊区对称点上的波函数。

We cross-matched the 4XMM-DR10 catalog with the HyperLEDA database and obtained the new sample of galaxies that contain X-ray sources. Excluding duplicate observations and false matches, we present a total of 7759 galaxies with X-ray sources. In the current work, we present general properties of the sample: namely the distribution in equatorial coordinates, radial velocity distribution, morphological type, and X-ray fluxes. The sample includes morphological classification for 5241 galaxies with X-ray emission, almost half of which, 42%, are elliptical (E, E-S0). Most galaxies in the sample have nuclear X-ray emission (6313 or 81%), and the remaining 1443 (19%) present X-ray emission from the host galaxy. This sample can be used for future deep studies of multi wavelengths properties of the galaxies with X-ray emission.
