    Fractal microscope for direct virus-cell interaction Monitoring
    (Одеський національний університет імені І. І. Мечникова, 2004) Fedchuk, Oleksandr P.; Fedchuk, A. O.; Fedchuk, A. S.; Shitikova, L. I.; Fedchuk, P. O.
    The fractal type of natural science laws’ understanding has become the leading one in biomedical research, especially in the last two decades. It takes start from the entropy based proof of the necessity of living cell to divide in order to survive. The Fourier t ran s form of the sensitive cell subs tra te was formed through laser diffraction patterning and used as the reference data. It was shown that each specimen could be marked with fractal dimension D which could be changed only in the process of non-equilibrium fractal growth and could serve as laboratory research identifier. It was shown experimentally that the viral particles attacking the sensitive substrate changes the D value at every stage of virus-cell interaction. All the mentioned features of the proposed fractal approach to the problem of virus-cell interaction makes it to be attractive and useful laboratory/clinical express-tool for the purposes of antiviral research, antiviral drug testing and clinical research.

    New general approach in the electron theory of catalytic processes on semiconductors and binary metallic materials
    (Одеський національний університет імені І. І. Мечникова, 2004) Glushkov, Oleksandr V.; Fedchuk, P. O.; Fedchuk, Oleksandr P.; Loboda, Andriy V.
    A problem of the catalytic activity definition for binary metallic alloys and heavily doped semiconductor materials is considered within a new quantum mechanical and electrodynamical approach.. There are found the quantitative link between the electron structure parameters of indicated materials and their catalytic activity on example of a simple model reactions of the following type: H = H+ -f- e and 0 ^ = 0 2 + e~. It has been found that the link between the Fermi level position dependence upon the metal alloy components concentration and their catalytic activity is quite tight.

    Semiconductor and liquid crystalline sensors in the problem of artificial intellect
    (Одеський національний університет імені І. І. Мечникова, 2001) Fedchuk, P. O.; Chemyr, I. O.; Fedchuk, Oleksandr P.; Horney, M. A.
    The interrelation between the peculiarities of artificial intellect model system components’ structural self-organization and the possibilities of adaptive dialog human—computer provision is studied. The fractal structure and self-organization of biologically ordered matter are considered to be the basis of signal scaling processes that occur in liquid crystalline— semiconductor contact sensors. It was shown that liquid crystalline structure is the most proper for replication of fractal structure details being always present at the surface of semiconductor wafer and their transfer into bulk of liquid crystal itself. The results obtained by the authors allow to predict the possibility of biomagnetic field registration by means of thin layer fractal structures with internal multiplication of the signal under registration.
