A method of forming coherent correlated states of particles to accelerate nuclear, chemical and biophysical processes in the presence of both damping ( dissipation) and influence external random force has been developed. It was shown that the correlated state could be formed under periodic and monotonic effect on the parameters of the potential well, where the particle was located. It wasis shown that the negative impact of dissipation on the correlation state could be neutralized by increasing the index (depth)of parametric modulation of the well parameters. Also it was first demonstrated that under the optimized parameters of impact on the particle, the probabilily of the tunnel effect could be very substantially increased, that allowed of accelerating by many orders nuclear and chemical (biochemical ) processes at low temperature and low energy of the interacting particles. An alternative approach to the description of the effect of diffusion in liquids has been applied. Instead of determining the dependence of the diffusion coefficient on the state and / or space-time variables, it was proposed to use other ( non-linear) law of diffusion , but with a transport coefficient ( mutual diffusion coefficient) , which was the system constant. It was found that only in the presence of a third substance the diffusion law became non-trivial and different from Fick's law . In general, the chemical reaction should be considered as a kind of nonlinear processes. As a result, macroscopic diffusion law becomes nonlinear , although mutual diffusion factor remains constant while the reaction proceeds. The nonlinear diffusion law was recorded for the special case of binary mixtures , and can be generalized for an arbitrary set of initial liquids as well as to account the effect of shrinkage ( swelling ) of the reaction products. The processes of synchronization of cortical minicolumns and hypercolumns as combining a large number of minicolumns have been investigated, the approptiate model has been realized. The methodology for solving the inverse problem of three-dimensional tomographic imaging for the scheme with a point source of radiation and a two-dimensional detector array has been practically tested. Construction of three-dimensional distribution of the absorption coefficient by biological object has been carried out on an example of a biological object phantom. The conditions of compliance of obtained results with classical convolution methods have been established
