]]>The limiting similarity of competitive species and its relationship with the competitive exclusion principle is still one of the most important concepts in ecology. In the 1970s, May [R. M. May, *Stability and Complexity in Model Ecosystems* (Princeton University, Princeton, NJ, 1973)] developed a con…

]]>A deterministic multiscale dynamical system is introduced and discussed as a prototype model for relative dispersion in stationary, homogeneous, and isotropic turbulence. Unlike stochastic diffusion models, here trajectory transport and mixing properties are entirely controlled by Lagrangian chaos. …

Dyadic Green function and perturbation expansion have been applied to get the slip length quantitatively. In the slip length, both the effects of the roughness of the interfaces and the chemical inter…

The scaling of the absolute moments against the aggregation horizon of real financial processes and of both uniscaling and multiscaling synthetic processes converges asymptotically towards linearity in log-log scale. In lig…
