A two-stage reaction (A+B→R,B+R→S) is studied, where the reactants A and B lie initially in an array of alternating striations. The product R is desired, and S is an unwanted by-product. A corresponding reaction–diffusion system in one spatial dimension is analysed in two special cases,...

In this paper we translate the two higher levels of the Ergodic Hierarchy  [11], the Kolmogorov level and the Bernoulli level, to quantum language. Moreover, this paper can be considered as the second part of  [3]. As in  [3], we consider the formalism where the states are positive...

Analysis of the Tsallis q-triplet for the variability of El Niño Southern Oscillation (ENSO) index during the Holocene epoch (last 11,000 years) is presented. Three periods are analyzed, 0–7000, 7000–9700, 9700–11,000 years before the present. During the first and the third periods, the...

Tsallis [Physica A 340 (2004) 1] identified a set of numbers, the “q-triplet” ≡{qstat, qsen, qrel}, for a system described by nonextensive statistical mechanics. The deviation of the q's from unity is a measure of the departure from thermodynamic equilibrium. We present observations of the...
