Abstract: At the present time reliably established that probability density functions of gene expression of microarray experiments possess a number of universal properties. First of all these distributions have power asymptotic and secondly the shape of these distributions are inherent for all organisms and tissues. This fact led to appearance of a number works where authors are investigating various probability distributions for approximation of empirical distributions of gene expression. In the work the gene expression of various organisms are investigated which were obtained from microarrays of various manufactures. The probability density functions of the gene expression levels are approximated by the fractional stable distribution. The parameters of the fractional stable distributions were statistically estimated according experimental data. It is shown that for all investigated samples the experimental distributions have the power-law asymptotic. At the same time the fractional stable dist

Abstract: In the experiments presented the effects of transmitting information derived from the growth hormone gibberellic acid (GA) to peas over a distance of some meters have been measured. Transmission of the biochemical characteristics of GA was achieved through a carrier wave of approximately 6.78 MHz running along a copper wire comparable to a strip line from the gibberellic acid as the source of information to the exposed peas, which reacted by a statistically significant enhanced root growth. The measured averages of the germinating pea root lengths were compared to control values, i.e. values corresponding to untreated peas. While continuous GA transmission resulted in an average increase of root length by approximately 50-60%, a singular burst of 15 minutes could increase roots’ length by an additional 42%, raising the increase relative to the control group by as much as 125% in total. Both values could be established with very high statistical significance. In a third experimental set
