Generalized Fractional Master Equation for Self-Similar Stochastic Processes Modelling Anomalous Diffusion [PDF]

open access: yesInternational Journal of Stochastic Analysis, 2012
The Master Equation approach to model anomalous diffusion is considered. Anomalous diffusion in complex media can be described as the result of a superposition mechanism reflecting inhomogeneity and nonstationarity properties of the medium. For instance, when this superposition is applied to the time-fractional diffusion process, the resulting Master ...

Extracting features of Gaussian self-similar stochastic processes via the Bandt-Pompe approach [PDF]

open access: yesPhysical Review E, 2007
By recourse to appropriate information theory quantifiers (normalized Shannon entropy and Martín-Plastino-Rosso intensive statistical complexity measure), we revisit the characterization of Gaussian self-similar stochastic processes from a Bandt-Pompe viewpoint.

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.

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

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 ...

Symmetric Stochastic Integrals with Respect to a Class of Self-similar Gaussian Processes [PDF]

open access: yesJournal of Theoretical Probability, 2018
We study the asymptotic behavior of the $ν$-symmetric Riemman sums for functionals of a self-similar centered Gaussian process $X$ with increment exponent $0(2\ell+1)^{-1}$, we prove that the convergence holds in probability.

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 ...

Methods for analysis of functionals on Gaussian self similar processes [PDF]

open access: yes, 2018
Many engineering and scientific applications necessitate the estimation of statistics of various functionals on stochastic processes. In Chapter 2, Norros et al’s Girsanov theorem for fBm is reviewed and extended to allow for non-unit volatility. We then
