An Analysis of Open-Ended Coaxial Probe Sensitivity to Heterogeneous Media [PDF]

open access: yesSensors, 2020
Open-ended coaxial probe spectroscopy is commonly used to determine the dielectric permittivity of biological tissues. However, heterogeneities in the probe sensing region can limit measurement precision and reproducibility.

Diffusion-limited reactions in dynamic heterogeneous media [PDF]

open access: yesNature Communications, 2018
“Diffusing diffusivity” concept has been recently put forward to account for rapid structural rearrangements in soft matter and biological systems. Here the authors propose a general mathematical framework to compute the distribution of first-passage ...

Anomalous Radiative Transfer in Heterogeneous Media. [PDF]

open access: yesAdv Theory Simul
AbstractMonte Carlo (MC) simulations are the gold standard for describing various transport phenomena and have largely contributed to the understanding of these processes. However, while their implementation for classical transport governed by exponential step‐length distributions is well‐established, widely accepted approaches are still lacking for ...

Nonlinear Poisson equation for heterogeneous media. [PDF]

open access: yesBiophys J, 2012
The Poisson equation is a widely accepted model for electrostatic analysis. However, the Poisson equation is derived based on electric polarizations in a linear, isotropic, and homogeneous dielectric medium. This article introduces a nonlinear Poisson equation to take into consideration of hyperpolarization effects due to intensive charges and possible

A Novel Coupled Meshless Model for Simulation of Acoustic Wave Propagation in Infinite Domain Containing Multiple Heterogeneous Media

open access: yesMathematics, 2023
This study presents a novel coupled meshless model for simulating acoustic wave propagation in heterogeneous media, based on the singular boundary method (SBM) and Kansa’s method (KS).

A Micromechanical Model of Additively Manufactured Aluminum Alloys [PDF]

open access: yesEPJ Web of Conferences, 2019
A micromechanical model is developed to predict the deformation behavior of additively manufactured aluminum alloys. Three-dimensional models of grain structures typical for different microregions of the melt pool are generated by the step-by-step ...

Fractal heterogeneous media [PDF]

open access: yesPhysical Review E, 2010
A method is proposed for generating compact fractal disordered media, by generalizing the random midpoint displacement algorithm. The obtained structures are invasive stochastic fractals, with the Hurst exponent varying as a continuous parameter, as opposed to lacunar deterministic fractals, such as the Menger sponge. By employing the Detrending Moving

Online Coupled Generalized Multiscale Finite Element Method for the Poroelasticity Problem in Fractured and Heterogeneous Media

open access: yesFluids, 2021
In this paper, we consider the poroelasticity problem in fractured and heterogeneous media. The mathematical model contains a coupled system of equations for fluid pressures and displacements in heterogeneous media.

Ranking in heterogeneous social media [PDF]

open access: yesProceedings of the 7th ACM international conference on Web search and data mining, 2014
The problem of image search has been studied extensively in recent years because of the large and increasing repositories of images on the web, social media, and other linked networks. Most of the available techniques for keyword-based image search on the web use the text in the surrounding or linked text in order to retrieve related images. Many image
