Research on a Fractal Dimension Calculation Method for a Nano-Polymer Microspheres Dispersed System

Frontiers in Chemistry, 2021
Polymer microspheres (PMs) are a kind of self-similar volume expansion particle, and their fractal dimension varies with hydration swelling. However, there is no unique fractal dimension calculation method for their characteristics.

Hurst Coefficient in long time series of population size: Model for two plant populations with different reproductive strategies

, 2010
Can the fractal dimension of fluctuations in population size be used to estimate extinction risk? The problem with estimating this fractal dimension is that the lengths of the time series are usually too short for conclusive results.
