Affinity tags have become powerful tools from basic biological research to structural and functional proteomics. They were widely used to facilitate the purification and detection of proteins of interest, as well as the separation of protein complexes.

Unlike the standard Bayesian theory, this utility model impl...

An interesting question is whether credit and equity rationing are mutually compatible, and how they interact.
