A mechanism of neutron transfer between nuclei in close low-energy collisions is established. It includes three stages: the transformation of the initial one-nuclear state into a two-nucleus state, the transitions of this state to other molecular states, and the transformation of those states into one-nuclear states in which nuclei are separated from one another. An explanation is offered for the fusion of nuclei in the 18O + 58Ni reac- tion exceeding the cross section, relative to the 16O + 60Ni reaction. © 2011 Allerton Press, Inc. Source

This study is an attempt to answer the question – what kind of spiking neural networks could efficiently transform rate-coded input signal into temporally coded form – specific activity of neuronal groups with strictly fixed temporal delays between spikes emitted by different neurons in every group. Since theoretical approach to the solution of this problem appears to be very hard or impossible the network configurations performing this task efficiently were found by means of genetic algorithm. Exploration of their structure showed that while excitatory neurons form the groups with stereotypical firing patterns, the inhibitory neurons of the network make these patterns specific for different rate-coded stimuli and, thus, play the key role in conversion of rate-coded input signal to temporal code. © Springer International Publishing Switzerland 2016.

The model of random smooth curvature for carbon nanotubes within the framework of the theory of random processes is proposed for describing the particle channeling in carbon nanotubes. The degree of influence of random nanotube axis deviation from the straight line on the particle channeling has been investigated with a specific choice for particular type of random processes. The conditions, at which the inaccuracy in given random type can be neglected at channeling, have been examined. © 2015 Elsevier B.V. Source

The aim of this research was to analyze the general somatic status and to compare the functional activities of the sympathetic versus parasympathetic parts of a patient’s vegetative nervous system in the formation of a particular type of age-related cataract. It has been for found that in cases of a cortical age-related cataract, the predominance of sympathetic effects of the vegetative nervous system and corresponding features of systemic diastrophic changes in tissues is typical. In cases of the nuclear type of senile cataract, on the other hand, the predominance of para-symptomatic effects, which led to dystrophic changes of a different type, was found. Therefore, the type of age-related cataract can be proposed as an accessible clinical marker of the character of the neuro-dystrophic process in a patient. © 2016, Pleiades Publishing, Ltd. Source

The probability of neutron transfer between nuclei at close low-energy collisions has been inves-tigated as a function of the energy of the neutron separation, the energy in a center-of-mass system E and the collision impact parameter. The energy dependence of the neutron transfer cross section in the 6He + 197Au reaction has been explained. © 2012 Allerton Press, Inc. Source
