Unravelling the origins of anomalous diffusion: from molecules to migrating storks
Anomalous diffusion or, more generally, anomalous transport, with nonlinear dependence of
the mean-squared displacement on the measurement time, is ubiquitous in nature. It has …

Time scales in the dynamics of political opinions and the voter model
Opinions in human societies are measured by political polls on time scales of months to
years. Such opinion polls do not resolve the effects of individual interactions but constitute a …

Inferring nonlinear fractional diffusion processes from single trajectories
We present a method to infer the arbitrary space-dependent drift and diffusion of a nonlinear
stochastic model driven by multiplicative fractional Gaussian noise from a single trajectory …

Trend analysis in the presence of short-and long-range correlations with application to regional warming
ET Phillips, M Höll, H Kantz, Y Zhou - Physical Review E, 2023 - APS
Many real-world time series exhibit both significant short-and long-range temporal
correlations. Such correlations enhance the errors of linear trend analysis. In this paper, we …
