The Opacity of Backbones

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2017
A backbone of a boolean formula F is a collection S of its variables for which there is a unique partial assignment aS such that F[aS] is satisfiable (Monasson et al. 1999; Williams, Gomes, and Selman 2003).  This paper studies the nontransparency of backbones.

open access: yesInternational Astronomical Union Colloquium, 1994
Let Iv(r, θ) be the intensity of radiation of frequency v, at a distance r from the centre of a star and in a direction making an angle θ to the outward normal. In a plane-parallel approximation the equation of radiative transfer is where 𝛋v is the opacity and jv the emissivity. The net outward flux of radiant energy is
