Recurrence quantification analysis as a tool for the characterization of molecular dynamics simulations
A molecular dynamics simulation of a Lennard-Jones fluid, and a trajectory of
the B1 immunoglobulin G-binding domain of streptococcal protein G (B1-IgG)
simulated in water are analyzed by recurrence quantification, which is
noteworthy for its independence from stationarity constraints, as well as its
ability to detect transients, and both linear and nonlinear state changes. The
results demonstrate the sensitivity of the technique for the discrimination of
phase sensitive dynamics. Physical interpretation of the recurrence measures is
also discussed.Comment: 7 pages, 8 figures, revtex; revised for review for Phys. Rev. E

NON LINEAR ASSESSMENT OF MUSICAL CONSONANCE
The position of intervals and the degree of musical consonance can be objectively
explained by temporal series formed by mixing two pure sounds covering an octave. This
result is achieved by means of Recurrence Quantification Analysis (RQA) without considering
neither overtones nor physiological hypotheses. The obtained prediction of a consonance can be
considered a novel solution to Galileo’s conjecture on the nature of consonance. It constitutes
an objective link between musical performance and listeners’ hearing activity
