saltation

  1. any changes of an abrupt nature that occur in the thalli of fungi either through mutation or the occurrence of segregation of parts of the thallus with different genetic make-up (HETEROKARYONS and HOMOKARYONS).
  2. the movement of soil particles by wind.
  3. the occurrence of a major mutation in a single generation, bringing about significant change.

To illustrate the concept of saltation, during the six-year diffusion of email and the World Wide Web, society transformed qualitatively differently than by "eight-fold," which is the multiplier of our hypothetical inflationary drivers over a six-year period (three doublings over the course of six years or 2 X 2 X 2 = 8).

The degree of depolarization of QHG beams has a saltation and reaches the minimum value at spectrum power-law exponent [alpha] = 11/3, the refractive index structure parameter at the ground of the turbulent atmosphere ([C.sup.2.sub.n](0)) slightly affects the polarization degree of QHG beams which have travelled a long distance, and the change of polarization degree decreases with the increasing zenith angle.
