Review article: Scaling, dynamical regimes, and stratification. How long does weather last? How big is a cloud? [PDF]

open access: yesNonlinear Processes in Geophysics, 2023
Until the 1980s, scaling notions were restricted to self-similar homogeneous special cases. I review developments over the last decades, especially in multifractals and generalized scale invariance (GSI).

A Drive towards Thermodynamic Efficiency for Dissipative Structures in Chemical Reaction Networks

open access: yesEntropy, 2021
Dissipative accounts of structure formation show that the self-organisation of complex structures is thermodynamically favoured, whenever these structures dissipate free energy that could not be accessed otherwise.

Can power-law scaling and neuronal avalanches arise from stochastic dynamics? [PDF]

open access: yesPLoS ONE, 2010
The presence of self-organized criticality in biology is often evidenced by a power-law scaling of event size distributions, which can be measured by linear regression on logarithmic axes. We show here that such a procedure does not necessarily mean that

On copulas of self-similar Ito processes

open access: yesDependence Modeling, 2021
We characterize the cumulative distribution functions and copulas of two-dimensional self-similar Ito processes, with randomly correlated Wiener margins, as solutions of certain elliptic partial differential equations.

Time scales in epigenetic dynamics and phenotypic heterogeneity of embryonic stem cells. [PDF]

open access: yesPLoS Computational Biology, 2013
A remarkable feature of the self-renewing population of embryonic stem cells (ESCs) is their phenotypic heterogeneity: Nanog and other marker proteins of ESCs show large cell-to-cell variation in their expression level, which should significantly ...

Estimation of stopping times for stopped self-similar random processes [PDF]

open access: yes, 2021
Let X=(Xt)t≥0 be a known process and T an unknown random time independent of X. Our goal is to derive the distribution of T based on an iid sample of XT. Belomestny and Schoenmakers (Stoch Process Appl 126(7):2092–2122, 2015) propose a solution based the

Identifying Arguments of Space-Time Fractional Diffusion: Data-Driven Approach

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
A plethora of complex dynamical systems from disordered media to biological systems exhibit mathematical characteristics (e.g., long-range dependence, self-similar and power law magnitude increments) that are well-fitted by fractional partial ...

The 𝑀-Wright Function in Time-Fractional Diffusion Processes: A Tutorial Survey

open access: yesInternational Journal of Differential Equations, 2010
In the present review we survey the properties of a transcendental function of the Wright type, nowadays known as 𝑀-Wright function, entering as a probability density in a relevant class of self-similar stochastic processes that we generally refer to as ...
