Self-interaction errors in nuclear energy density functionals
When applied to a single nucleon, nuclear energy density functionals may
yield a non-vanishing internal energy thus implying that the nucleon is
interacting with itself. It is shown how to avoid this unphysical feature for
semi-local phenomenological functionals containing all possible bilinear
combinations of local densities and currents up to second order in the
derivatives. The method outlined in this Rapid Communication could be easily
extended to functionals containing higher order terms, and could serve as a
guide for constraining the time-odd part of the functional
Finite subgroups of simple algebraic groups with irreducible centralizers
We determine all finite subgroups of simple algebraic groups that have
irreducible centralizers - that is, centralizers whose connected component does
not lie in a parabolic subgroup.Comment: 24 page

Color identification testing device
Testing device, which determines ability of a technician to identify color-coded electric wires, is superior to standard color blindness tests. It tests speed of wire selection, detects partial color blindness, allows rapid testing, and may be administered by a color blind person
