Superelastic Fire‐Safe Aerogel with Hierarchical Structures via Dual Templates Aided by Microbubble Engineering

Advanced Science, EarlyView.
Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.

A holistic approach to determine tree structural complexity based on laser scanning data and fractal analysis

Ecology and Evolution, 2017
The three‐dimensional forest structure affects many ecosystem functions and services provided by forests. As forests are made of trees it seems reasonable to approach their structure by investigating individual tree structure.

A tutorial introduction to adaptive fractal analysis [PDF]

Frontiers in Physiology, 2012
The authors present a tutorial description of adaptive fractal analysis (AFA). AFA utilizes an adaptive detrending algorithm to extract globally smooth trend signals from the data and then analyzes the scaling of the residuals to the fit as a function of the time scale at which the fit is computed.
