Many simple natural phenomena are characterized by complex motion that appears random at first glance, but that often displays underlying […]

The main motivation of this paper is to introduce the permutation Jensen-Shannon distance, a symbolic tool able to quantify the […]

Since Bandt and Pompe’s seminal work, permutation entropy has been used in several applications and is now an essential tool […]

One of the most useful tools for distinguishing between chaotic and stochastic time series is the so-called complexity-entropy causality plane. […]

The search for patterns in time series is a very common task when dealing with complex systems. This is usually […]

In this work, we investigate some statistical properties of symbolic sequences generated by a numerical procedure in which the symbols […]
