In this paper, the autoconvolution method was investigated to determine the position of the longitudinal axis of the photonic crystal fiber and to determine the center of the mode field in the cross section. Knowing the center of the PCF mode field, one can determine the cross section in which the diameter of the mode field will be maximal. This allows a more precise positioning of two identical PCF during connection. The proposed method allows improving the quality of the positioning of the PCF by transverse, angular, longitudinal displacements, and also by the mutual angle of rotation of the connected PCFs.

The research of the psychophysiological state of winterers of the Antarctic station "Academician Vernadsky" was carried out in order to establish the feasibility of their subsequent stay at the station and fulfill their service tasks. Short-term stay of polar explorers under difficult conditions causes stressful effects and nonspecific adaptive reactions. Their organisms must adapt to the exposure of various extreme factors and, in the first turn, natural ones. Considering that hematopoiesis is an important mechanism on which the ultimate adaptive result depends, a study of blood parameters was performed. It has been found that there are some changes in certain blood parameters that are not relevant with the reference norms for the studied polar groups. In this connection, there is a problem in adjusting the reference intervals for them. In order to determine the reference intervals, it is necessary to take into account the uncertainty of their establishment, having previously analyzed the sources of uncertainty.

The approach to the evaluation of the functional state of the human body as a system with a set of interrelated functional subsystems of the homeostatic type is proposed. The approach is considered on the basis of an assessment of the state of the respiratory subsystem, which can be described by a complex of statistically stable medical and biological indicators. Indicators obtained during monitoring of the state of polar explorers of the XXI Antarctic expedition at the station "Academician Vernadsky" in difficult conditions that can be attributed to the extreme. It was established that when forming the rules for making decisions on the suitability of winterers for further staying in the conditions of the action of extreme factors it is necessary to consider not only the values of the indicators of the state of the subsystems of the organism, but also their accuracy parameters. The analysis of the uncertainty of the obtained indicators by the proposed information model is carried out. It is shown that in this case it is necessary to take into account the features of a biological object, which has an individual and group variation.

In the present study we have focused on synthesis and characterization of nanocomposite for photodynamic therapy. The nanocomposite consisted of gold nanoparticles and photosensitizer Chlorin e6 incorporated into star-like polymer Dextran-graft-Polyacrylamide. The behavior of three-component nanosystem in the region of physiological temperatures was studied by using Dynamic Light Scattering. A small change in the size of polymer aggregates was observed at an increase in temperature from 25 ° C to 45 ° C. However, size of gold nanoparticles remained around 10 nm at all temperatures. The absorption spectra of nanosystem revealed the interaction of the photosensitizer Chlorine e6 with gold nanoparticles.In vitro testing of studied nanocomposite efficiency for Photodynamic therapy was carried out on the sub-lines of breast carcinoma MCF-7/S; MCF-7/Dox, and Jurkat cells. After irradiation with laser the death of 68.4% of MCF-7/S cells was registered. However, for MCF-7/Dox cells - 24.9%, for Jurkat cell line - 20 %. It was proved that prhotodynamic efficacy of proposed nanocomposite was depended on malignant cells type, while slight aggregation process not significantly affected nanosystem activity.

We numerically investigate the spectral properties of multi-periodic metamaterials of various configurations (the planar double-periodic photonic crystal and the bulk double-periodic magnetophotonic crystal) in the frequency range 15-45 GHz. In the first part of this paper we describe investigation of structure of the planar double periodic photonic crystal (PDPPC) which consists of two planar photonic crystals with large and small periods. A PDPPC unit cell consists of a series-connected narrow and wide segments of a microstrip transmission line. In the second part of this paper we will discuss results of investigation of a double-periodic magnetophotonic crystal (DPMPC) which consists of 3 unit cells. Each cell consists of periodically located 9 dielectric layers of quartz and teflon. On the border of the cell there is one layer of ferrite.We showed that both for a PDPPC and for a DPMPC in the transmission spectrum of these structures under study, a number of features arise: namely, narrow transmission peaks caused by the superposition of two spectra (with large and small periods) are observed in the stop bands of the spectrum. Such features may further allow the creation of a narrow-band filter for several frequencies for both planar structures and bulk ones.

In this paper, we consider theory of self-organization of periodic coupled temperature and strain (TS) fields on surfaces of anisotropic (transversely isotropic) solids irradiated by laser pulses. Laser-induced thermal field is treated as consisting of "atomic point defects" of a crystalline lattice - thermal phonons. The self-organization of TS structures occurs due to strain-thermal instability associated with a strain-induced flux of thermal phonons. Using the non-local forms of constitutive equations, a synergetic model of the process is formulated and substantiated, based on self-consistent dynamic equations for temperature and atomic displacements fields of the elastic continuum. Dispersion equation for instability is obtained and analyzed. It is observed that the length of non-local defect-atom interaction has a significant effect on the characteristics (growth rate, period) emerging strain-temperature surface structures. The period of these structures is proportional to the intrinsic length parameter and has a nanometer scale

The iteration method of angular spectrum is applied to the calculation of the Fabry-Pérot-resonator of a microchip laser with the given geometry. The resonator contains a phase diffraction optical element serving for the formation of a Gaussian or super-Gaussian emission beam. The maximum values of the diameter of the output aperture of a laser and the beam waist, at which the convergence of the iteration process holds (i.e., the undistorted output beam is formed), are evaluated.

The research paper presents a model for studying both the parameters and dynamics of laser light as a nonlinear dynamic system. The model provides for the measurement of the values of physical quantities by non-linear metrology methods and the analysis of the research findings with topological tools. The model is based on the assumption of interval values of the measured values and the possibility of changing the stationary dynamics into the random one. The model contains an experiment scheme and a procedure for evaluating measurement results. The peculiarity of the model lies in its systemic approach and suitability for measuring and researching stationary and chaotic modes. The model provides for the measurement of the emission parameter values intervals in various modes, of their stability values and time series prediction. Classification of the system dynamics is performed using the fractal dimension. The model can be used both to ensure the stability of the laser light parameters, and to obtain and control random emission.
