Orbitopal Fixing

Discrete Optimization, 2007
The topic of this paper are integer programming models in which a subset of 0/1-variables encode a partitioning of a set of objects into disjoint subsets. Such models can be surprisingly hard to solve by branch-and-cut algorithms if the order of the subsets of the partition is irrelevant, since this kind of symmetry unnecessarily blows up the search ...

PERIODATE-LYSINE-PARAFORMALDEHYDE FIXATIVE A NEW FIXATIVE FOR IMMUNOELECTRON MICROSCOPY

, 1974
A new fixative which primarily stabilizes carbohydrate moieties was developed for immunoelectron microscopy. It contains periodate, lysine and paraformaldehyde. Theoretically, the carbohydrates are oxidized by periodate and cross-linked by lysine.
