Protein cleavage during virus assembly: a novel specificity of assembly dependent cleavage in bacteriophage T4.

abstract：:The Landau spectrum of bismuth is complex and includes many angle-dependent lines in the extreme quantum limit. The adequacy of single-particle theory to describe this spectrum in detail has been an open issue. Here, we present a study of angle-resolved Nernst effect in bismuth, which maps the angle-resolved Landau sp...
