On an Integral Equation with the Riemann Function Kernel
Axioms, 2022 This paper is concerned with a study of a special integral equation. This integral equation arises in many applied problems, including transmutation theory, inverse scattering problems, the solution of singular Sturm–Liouville and Shrödinger equations, and the representation of solutions of singular Sturm–Liouville and Shrödinger equations.

Coagulation‐Fragmentation Equations with Multiplicative Coagulation Kernel and Constant Fragmentation Kernel [PDF]
Communications on Pure and Applied Mathematics, 2021 AbstractWe study a critical case of coagulation‐fragmentation equations with multiplicative coagulation kernel and constant fragmentation kernel. Our method is based on the study of viscosity solutions to a new singular Hamilton‐Jacobi equation, which results from applying the Bernstein transform to the original coagulation‐fragmentation equation.

On the Pseudo-Resolvent to the Kernel of an Integral Equations [PDF]
Transactions of the American Mathematical Society, 1912 The method developed by FredholmI for the solution of a non-homogeneous linear integral equation is comparatively simple in case the corresponding homogeneous equation admits no solutions not identically zero; in terms of the determinant and the first minor for the kernel of the given equation a resolvent function is defined, by means of which the ...

Scattering kernels for the muon diffusion equation [PDF]
Physical Review A, 1988 Diffusion of muonic hydrogen atoms in gaseous hydrogen is studied. Scattering kernels are derived from the kinematics of an inelastic binary collision. The effect of rotations of the hydrogen molecules is treated by defining and computing an effective inelastic energy transfer Q/sub eff/.

A Comparison of Covariates, Equating Designs, and Methods in Equating TIMSS 2019 Science Tests [PDF]
, 2023 This research aimed to compare the equated scores by the methods based on classical test theory (CTT) and kernel equating, using covariates design (NEC) and anchor test design (NEAT).

Kernel estimates for nonautonomous Kolmogorov equations
Advances in Mathematics, 2016 Using time dependent Lyapunov functions, we prove pointwise upper bounds for the heat kernels of some nonautonomous Kolmogorov operators with possibly unbounded drift and diffusion coefficients.

Item Response Theory Observed-Score Kernel Equating
, 2017 Item response theory (IRT) observed-score kernel equating is introduced for the non-equivalent groups with anchor test equating design using either chain equating or post-stratification equating. The equating function is treated in a multivariate setting

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

On the theory of integral equations with discontinuous kernels [PDF]
Transactions of the American Mathematical Society, 1926 This paper is concerned with the theory of the integral equation whose salient characteristic is that its kernel K(x, t) is discontinuous along the line t =x. It is closely related with the theory of the integral equation characterized by discontinuities in the partial derivatives of the kernel for t=x, of which more specific mention is made below. The
