A symbolic encoding scheme, based on the ordinal relation between the amplitude of
neighboring values of a given data sequence, should be implemented before estimating the …

The main motivation of this paper is to introduce the permutation Jensen-Shannon distance,
a symbolic tool able to quantify the degree of similarity between two arbitrary time series …

Modern high-power lasers exhibit a rich diversity of nonlinear dynamics, often featuring
nontrivial co-existence of linear dispersive waves and coherent structures. While the …

The search for patterns in time series is a very common task when dealing with complex
systems. This is usually accomplished by employing a complexity measure such as …

The family of image visibility graphs (IVG/IHVGs) have been recently introduced as simple
algorithms by which scalar fields can be mapped into graphs. Here we explore the …

A landmark of statistical mechanics, spin-glass theory describes critical phenomena in
disordered systems that range from condensed matter to biophysics and social dynamics …

Raman random fiber laser (RRFL) is a complex physical system that arises from the
distributed Raman amplification and the intrinsic stochasticity of fiber scattering. The …

Complex networks theory have gained wider applicability since methods for transformation
of time series to networks were proposed and successfully tested. In the last few years …

We use ordinal analysis and spatial permutation entropy to distinguish between eyes-open
and eyes-closed resting brain states. To do so, we analyze EEG data recorded with 64 …

We report the direct observation of the onset of turbulence in propagating one-dimensional
optical waves. The transition occurs as the disordered hosting material passes from being …
