An endogenous crepuscular rhythm of rainbow trout (Salmo gairdneri) photomechanical movements [PDF]

open access: yes, 1982
1. The position of the epithelial pigment and cones in the retina of Salmo gairdneri was determined during extended periods of darkness in fish entrained to both artificial and natural light/dark cycles. 2. An endogenous rhythm of such photomechanical

An upper bound on the fractional chromatic number of triangle-free subcubic graphs

open access: yes, 2014
An $(a:b)$-coloring of a graph $G$ is a function $f$ which maps the vertices of $G$ into $b$-element subsets of some set of size $a$ in such a way that $f(u)$ is disjoint from $f(v)$ for every two adjacent vertices $u$ and $v$ in $G$.

The Rainbow Site, An Unusual Syrup Mill in Gregg County, Texas [PDF]

open access: yes, 2005
The Rainbow site is a historic archaeological site that was recorded during a cultural resources survey of a proposed Wal-Mart SuperCenter site in Longview, Texas. It was first interpreted as the location of an illegal whiskey still, but testing revealed

Assessing the contributions of surface waves and complex rays to far-field Mie scattering by use of the Debye series [PDF]

open access: yes, 1992
The contributions of complex rays and the secondary radiation shed by surface waves to scattering by a dielectric sphere are calculated in the context of the Debye series expansion of the Mie scattering amplitudes.
