[Dynamic structures and nonlinear spectral transformations based on structure interaction reactions]

A notion of dynamic excitation structure (DES) is introduced. Such structure is a mobile picture which adequately reflects external nonstationary excitation spectra. The stimulated structure transitions are possibly caused by DES generation if the substrate structure has space-time polimorphism. The stimulated associative transitions can be a basis of structure-holographic information processing in biological systems. Possibility of associative transformations of nonstationary processes is discussed and elements of associative structure logic are given. The model of semantic organization of nonequilibrium cooperative systems is discussed. This model may be useful for explaining the gnosiological activity of biological objects.
