The interaction of particles with planar defects in semiconductor crystal was studied on the basis of a model of the band energy-spectrum structure. Generalized localized states are shown to exist in the vicinity of defects. It is also shown that nonquadratic dispersion law gives rise to quasi-localized states. Particle scattering by the semiconductor boundary was analyzed. The condition for the total reflection from the interface is formulated as follows: the incident-particle energy should be equal to the energy of a quasi-localized state. It was found that a weak dissipation of particle energy in the crystal causes instability of the resonance condition for the total reflection. __________ Translated from Fizika i Tekhnika Poluprovodnikov, Vol. 34, No. 11, 2000, pp. 1333–1338.

The effects of background millimeter radiations (BMR) in patients with coronary artery disease (CAD), hypertension and in subjects with Inherited real risk of CAD, were investigated through invariant statistic measures, typical of nonlinear dynamics analysis of biological systems. The experimental evidences show that BMR ameliorate the nonlinear complexity in biosystems, recognized sign of physiological behavior, by increasing both the rate of unpredictability of heart rate variability (HRV) in patients with metabolic syndrome and the fractal dimension of coronary microvessel oscillations in subjects with pre-metabolic syndrome, healing their genetic alteration and CAD Inherited real risk.  相似文献
