The Dyadic Fractional Diffusion Kernel as a Central Limit
(Springer Heidelberg, 2019-03)
We obtain the fundamental solution kernel of dyadic diffusions in ℝ + as a central limit of dyadic mollification of iterations of stable Markov kernels. The main tool is provided by the substitution of classical Fourier ...
An Investigation of Chaotic Diffusion in a Family of Hamiltonian Mappings Whose Angles Diverge in the Limit of Vanishingly Action
(2018-01-01)
The chaotic diffusion for a family of Hamiltonian mappings whose angles diverge in the limit of vanishingly action is investigated by using the solution of the diffusion equation. The system is described by a two-dimensional ...
Application of the diffusion equation to prove scaling invariance on the transition from limited to unlimited diffusion
(2020-07-01)
The scaling invariance for chaotic orbits near a transition from limited to unlimited diffusion in a dissipative standard mapping is explained via the analytical solution of the diffusion equation. It gives the probability ...
DIFFUSION-COEFFICIENTS OF AQUEOUS PHENOLS DETERMINED BY THE TAYLOR DISPERSION TECHNIQUE - EVIDENCE FOR SOLUTE ADSORPTION ON THE WALLS OF TEFLON TUBING

Diffusive limit to a selection-mutation equation with small mutation formulated on the space of measures
(American Institute of Mathematical Sciences, 2021-03)
In this paper we consider a selection-mutation model with an advection term formulated on the space of finite signed measures on Rd. The selection-mutation kernel is described by a family of measures which allows the study ...
The Shannon entropy as a measure of diffusion in multidimensional dynamical systems
(Springer, 2018-04)
In the present work, we introduce two new estimators of chaotic diffusion based on the Shannon entropy. Using theoretical, heuristic and numerical arguments, we show that the entropy, S, provides a measure of the diffusion ...
Nitrogen diffusion in niobium under low pressure
(2014)
The interaction among heavy interstitial atoms present in metals with bcc structure is studied using anelastic spectroscopy. This technique makes it possible to obtain information on interstitial concentration, precipitation, ...
