Density and uniform density [PDF]

Proceedings of the American Mathematical Society, 1964
Starting from a chosen point 0 on the circle of unit circumference and travelling counterclockwise around the circle, lay off arc lengths p, 2p, 3p, * * *, from 0. Designate the sequence of points so obtained by (p), (2p), (3p), * * *, and call the sequence S.

A consistent and accurate ab initio parametrization of density functional dispersion correction (DFT-D) for the 94 elements H-Pu.

Journal of Chemical Physics, 2010
The method of dispersion correction as an add-on to standard Kohn-Sham density functional theory (DFT-D) has been refined regarding higher accuracy, broader range of applicability, and less empiricism.

Correction of Density Estimators that are not Densities

Scandinavian Journal of Statistics, 2003
Abstract. Several old and new density estimators may have good theoretical performance, but are hampered by not being bona fide densities; they may be negative in certain regions or may not integrate to 1. One can therefore not simulate from them, for example.
