TL;DR: It is concluded that nonlinear analysis is primarily useful in animal vocalizations with strong harmonic components (including subharmonics and biphonation) or low-dimensional chaos.

TL;DR: Ex vivo bioluminescent imaging of cultured SCN slices of young and aged PER2::luciferase knock-in mice revealed that aged SCN cells showed longer circadian periods and that the rhythms of individual cells rapidly became desynchronized, suggesting that aging degrades the SCN circadian ensemble but that recurrent LD cycles mask these effects.

TL;DR: The results reveal the spatial structure of the plant clock and suggest that unlike the centralised mammalian clock, the Arabidopsis clock has multiple coordination points.

TL;DR: This paper studies global bifurcation structure of the chaotic neural networks applied to solve the traveling salesman problem and finds that the crisis-induced intermittent switches among the ruins of the previous localized chaotic attractors underly the ‘chaotic search’ for TSP solutions.

TL;DR: An approach is presented for extracting phase equations from multivariate time series data recorded from a network of weakly coupled limit cycle oscillators to estimate important properties of the phase equations including natural frequencies and interaction functions between the oscillators.
