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 ...

Social Influence on Observed Race

open access: yesSociological Science, 2018
This article introduces a novel theoretical approach for understanding racial fluidity, emphasizing the social embeddedness of racial classifications. We propose that social ties affect racial perceptions through within-group micromechanisms, resulting ...

Macroscopic Quantum-Type Potentials in Theoretical Systems Biology

open access: yesCells, 2013
We review in this paper the use of the theory of scale relativity and fractal space-time as a tool particularly well adapted to the possible development of a future genuine systems theoretical biology.

Collective dynamics of gene expression in cell populations.

open access: yesPLoS ONE, 2011
The phenotypic state of the cell is commonly thought to be determined by the set of expressed genes. However, given the apparent complexity of genetic networks, it remains open what processes stabilize a particular phenotypic state.

Invariance properties of the negative binomial Levy process and stochastic self-similarity [PDF]

open access: yesInternational Mathematical Forum, 2007
We study the concept of self-similarity with respect to stochastic time change. The negative binomial process (NBP) is an example of a family of random time transformations with respect to which stochastic self-similarity holds for certain stochastic processes.

Stochastic simulation of destruction processes in self-irradiated materials

open access: yesCondensed Matter Physics, 2017
Self-irradiation damages resulting from fission processes are common phenomena observed in nuclear fuel containing (NFC) materials. Numerous α-decays lead to local structure transformations in NFC materials.

Continuous time volatility modelling: COGARCH versus Ornstein-Uhlenbeck models [PDF]

open access: yes, 2005
We compare the probabilistic properties of the non-Gaussian Ornstein-Uhlenbeck based stochastic volatility model of Barndorff-Nielsen and Shephard (2001) with those of the COGARCH process.

Coevolving edge rounding and shape of glacial erratics: the case of Shap granite, UK [PDF]

open access: yesEarth Surface Dynamics
The size distributions and the shapes of detrital rock clasts can shed light on the environmental history of the clast assemblages and the processes responsible for clast comminution.

Self-dual continuous processes [PDF]

open access: yes, 2013
The important application of semi-static hedging in financial markets naturally leads to the notion of conditionally quasi self-dual processes which is, for continuous semimartingales, related to conditional symmetry properties of both their ordinary as ...
