An Adaptive Nonconforming Finite Element Algorithm for Laplace Eigenvalue Problem
Abstract and Applied Analysis, 2014 We establish Crouzeix-Raviart element adaptive algorithm based on Rayleigh quotient iteration and give its a priori/a posteriori error estimates. Our algorithm is performed under the package of Chen, and satisfactory numerical results are obtained.

Anatomy of a SPAN Particle: A Four‐Level Structural Framework for Lithium–Sulfur Batteries
EcoEnergy, EarlyView.Sulfurized polyacrylonitrile (SPAN) is a key cathode material for batteries. Borrowing the four‐level classification of protein structure, this perspective demonstrates SPAN's structural complexity into well‐defined levels, giving researchers clear research boundaries and targets at each level for improving battery performance.

The prevalence of Streptococcus equi subsp. equi carriers in the Netherlands
Equine Veterinary Journal, EarlyView.Abstract Background Streptococcus equi subspecies equi (S. equi) carriers are thought to be important drivers for strangles outbreaks. Limited data are available on the prevalence of carriers in European horse husbandry settings. Objectives To estimate the prevalence of S.

Penalty algorithm adapted for the spectral element discretization of the Darcy equations
Boundary Value Problems, 2019 Any spectral element discretization of the Darcy problem can be efficiently solved by applying the penalty method. This method leads to a system of equations with uncoupled unknowns.

On Optimized Extrapolation Method for Elliptic Problems with Large Coefficient Variation
Journal of Algorithms & Computational Technology, 2007 A posteriori error estimators are fundamental tools for providing confidence in the numerical computation of PDEs. In this paper we present a new technique that produces global a posteriori error estimates based on an optimized extrapolation method.
