Do negative absolute temperatures matter physics and specifically Statistical Physics? We
provide evidence that we can certainly answer positively to this vexata quaestio. The great …

Many physical systems characterized by nonlinear multiscale interactions can be modelled
by treating unresolved degrees of freedom as random fluctuations. However, even when the …

The data analysis of physical observables has a long tradition in the field of nonlinear
dynamics and complex systems. Much effort has been devoted to answering the question of …

Natural and manmade complex systems are comprised of different elementary units, being
either system components or diverse subsystems as in the case of networked systems …

Time series often exhibit a combination of long-range drift and short-term stochastic
fluctuations. Traditional methods for analyzing such series involve fitting regression models …

Stochastic processes are encountered in many contexts, ranging from generation sizes of
bacterial colonies and service times in a queueing system to displacements of Brownian …

The integral length scale (LL) is considered to be characteristic of the largest motions of a
turbulent flow, and as such, it is an input parameter in modern and classical approaches of …

We present an open-source package that helps the user to perform a basic statistical
analysis of a given turbulence dataset. We believe that this package is useful to the entire …

The interplanetary magnetic field carried out from the Sun by the solar wind displays
fluctuations over a wide range of scales. While at large scales, say at frequencies lower than …

Processes leading to anomalous fluctuations in turbulent flows, referred to as intermittency,
are still challenging. We consider cascade trajectories through scales as realizations of a …
