Table 3 Analytical expressions for various descriptors of oligomer population dynamics [114]. ρo1 and ρo2 represent the rates of oligomer formation via primary and secondary nucleation, respectively, ρ+ represents the rate for fibril elongation, ρc represents the rate of oligomer conversion, and ρe represents the combined rates of oligomer conversion and dissociation
