Fractal Stochastic Processes on Thin Cantor-Like Sets

open access: yesMathematics, 2021
We review the basics of fractal calculus, define fractal Fourier transformation on thin Cantor-like sets and introduce fractal versions of Brownian motion and fractional Brownian motion. Fractional Brownian motion on thin Cantor-like sets is defined with

Detection of Bacteria-Induced Early-Stage Dental Caries Using Three-Dimensional Mid-Infrared Thermophotonic Imaging

open access: yesBioengineering, 2023
Tooth decay, or dental caries, is a widespread and costly disease that is reversible when detected early in its formation. Current dental caries diagnostic methods including X-ray imaging and intraoral examination lack the sensitivity and specificity ...

Evaluating time domain reflectometry and coaxial impedance sensors for soil observations by the U.S. Climate Reference Network

open access: yesVadose Zone Journal, 2020
The objective of this study was to evaluate the performance of two commercial‐grade electromagnetic sensors in measuring soil water content for the U.S. Climate Reference Network (USCRN). One sensor was a 50‐MHz coaxial impedance dielectric sensor (model

Negative Correlation between the Diffusion Coefficient and Transcriptional Activity of the Glucocorticoid Receptor [PDF]

open access: yes, 2017
The glucocorticoid receptor (GR) is a transcription factor, which interacts with DNA and other cofactors to regulate gene transcription. Binding to other partners in the cell nucleus alters the diffusion properties of GR.

Reaction-diffusion processes with nonlinear diffusion [PDF]

open access: yesPhysical Review E, 2012
We study reaction-diffusion processes with concentration-dependent diffusivity. First, we determine the decay of the concentration in the single-species and two-species diffusion-controlled annihilation processes. We then consider two natural inhomogeneous realizations.

BDHI: a French national database on historical floods

open access: yesE3S Web of Conferences, 2016
The paper describes the various features of the BDHI database (objects, functions, content). This document database provides document sheets on historical floods from various sources: technical reports from water authorities, scientific accounts ...

The effect of yeast-derived β-glucans in reducing the adverse outcome of Lawsonia intracellularis in finishing pigs

open access: yesFrontiers in Animal Science, 2023
IntroductionChronic diarrhoea is one of the most recurrent health issues in pig herds. Among Q9 the causative agents of diarrhoea, Lawsonia intracellularis is quite frequent with worldwide distribution leading to detrimental economical losses, as a ...

Strong Stationary Duality for Diffusion Processes

open access: yes, 2015
We develop the theory of strong stationary duality for diffusion processes on compact intervals. We analytically derive the generator and boundary behavior of the dual process and recover a central tenet of the classical Markov chain theory in the ...

Natural Fibre-Reinforced Biofoams

open access: yesInternational Journal of Polymer Science, 2011
Starches and polylactic acids (PLAs) represent the main biobased and biodegradable polymers with potential industrial availability in the next decades for “bio” foams applications.

CO diffusion and desorption kinetics in CO$_2$ ices

open access: yes, 2017
Diffusion of species in icy dust grain mantles is a fundamental process that shapes the chemistry of interstellar regions; yet measurements of diffusion in interstellar ice analogs are scarce.
