Refined composite variable-step multiscale multimap** dispersion entropy: a nonlinear dynamical index
Nonlinear dynamical index can measure the complexity for a single time scale of the series, and when combined with coarse-grained methods, multiple time scales can be obtained to extract more information. In t...

Simplified coded dispersion entropy: a nonlinear metric for signal analysis
Recently, coded permutation entropy has been proposed, which enhances the noise immunity by quadratic partitioning on the basis of permutation entropy. However, coded permutation entropy and permutation entrop...

Robust aramid nanopaper based on the uniform wrap of sodium alginate on the surface of nanofibers
Compared to the individual fiber, the core problem limiting the mechanical strength of the aramid nanopaper is the weak interfacial bonding strength, and the hydrogen bond-induced aggregation is an important f...
