Quantum electrodynamics
TL;DR: In this paper, the subject of quantum electrodynamics is presented in a new form, which may be dealt with in two ways: using redundant variables and using a direct physical interpretation.

Electron–molecule collision calculations using the R-matrix method
TL;DR: The R-matrix method is an embedding procedure which is based on the division of space into an inner region where the physics is complicated and an outer region for which greatly simplified equations can be solved.

Solar UV and X-ray spectral diagnostics
Giulio Del Zanna,Helen E. Mason +1 more
TL;DR: In this article, a review of the diagnostic methods used to measure electron densities, electron temperatures, differential emission measure (DEM), and relative chemical abundances is presented, focusing on the optically thin emission from the solar atmosphere, mostly found at UV and X-ray (XUV) wavelengths.

A practical guide to splines
TL;DR: This book presents those parts of the theory which are especially useful in calculations and stresses the representation of splines as linear combinations of B-splines as well as specific approximation methods, interpolation, smoothing and least-squares approximation, the solution of an ordinary differential equation by collocation, curve fitting, and surface fitting.
