Fast numerical solution of weakly singular Volterra integral equations
Journal of Computational and Applied Mathematics, 1988 The authors present an algorithm for the solution of nonlinear, weakly singular Volterra integral equations of the form \[ y(t)=f(t)+1/\sqrt{\pi}\int^{t}_{0}(t-s)^{-1/2}k(t-s)g(s,y(s))ds, \] whose solution is assumed to be a smooth function of \(\sqrt{t}\).

Magnetic Force Microscopy Signatures of Higher‐Order Skyrmions and Antiskyrmions
Advanced Functional Materials, EarlyView.Magnetic force microscopy operated under vacuum conditions enables the qualitative identification of higher‐order skyrmions and antiskyrmions in Co/Ni multilayers at room temperature. Distinct stray‐field contrast signatures arise from vertical Bloch lines and complex domain‐wall configurations.

Collocation Solutions of a Weakly Singular Volterra Integral Equation
TEMA - Tendências em Matemática Aplicada e Computacional, 2007 The discrete superconvergence properties of spline collocation solutions for a certain Volterra integral equation with weakly singular kernel are analyzed. In particular, the attainable convergence orders at the collocation points are examined for certain choices of the collocation parameters.

Advanced Functional Materials, EarlyView.Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Advanced Functional Materials, EarlyView.ABSTRACT Metal oxide (MOx)‐based NO2 gas sensors typically require high temperatures or ultraviolet light, limiting their practical use. To enable visible‐light activation at room temperature, efficient and stable photosensitizers should be integrated with nanostructured MOx hosts.
