Trends do not always combine in a simple linear manner when combining samples, because of nonlinearity in the least - squares process. (climateaudit.org)
Due to the small extent of optical nonlinearity in naturally occurring materials, high light intensities and long propagation distances in nonlinear crystals are typically required to produce detectable nonlinear optical effects. (sciencedaily.com)
Recurrent neural network models trained to perform the task revealed that temporal scaling emerges from nonlinearities in the network and that the degree of scaling is controlled by the strength of external input. (csne-erc.org)
