Let r, k be positive integers, s(< r), a nonnegative integer, and n = 2r − s + k. The set of r-subsets of [n] = {1, 2,. .. , n} is denoted by [n] r. The generalized Kneser graph K(n, r, s) is the graph whose vertex-set is [n] r where two r-subsets A and B are joined by an edge if |A ∩ B| s. This note determines the diameter of generalized Kneser graphs.… (More)

BACKGROUND
Finding a suitable delivery system to improve the water solubility of hydrophobic drugs is a critical challenge in the development of effective formulations. In this study, we used A6K, a self-assembling surfactant-like peptide, as a carrier to encapsulate and deliver hydrophobic pyrene.
METHODS
Pyrene was mixed with A6K by magnetic stirring to… (More)
