... replace the o(n −7/2 ) error term in the asymptotic expansion of B(n)/n!withO(n −9/2 ln 19 n). The following extension of Theorem 1 (the case m = 3) giving a complete asymptotic expansion of I(n, ... number of permutations of {1, ,n} with precisely k inversions. We represent b(n, k) as a real trigonometric integral and then use the method of Laplace to give a complete asy...

... (we follow the terminology of [4]). If G =(V,E)isak-critical graph, then the low-vertex subgraph of G, denoted by L(G), is the subgraph of G, induced by all vertices of degree k − 1. The high-vertex ... ingredient of our proof is the following result of Stiebitz. Lemma 3 ([5]) Let G be a k-critical graph containing at least one vertex of degree k − 1. Then the number...

Furthermore, this stoichiometry was independent of the carbon sour...

This poses the obvious questions of whether the heterooligomeric c ring can promote ATP synthe- sis, whether the c subunit stoichiometry is variable, and, if so, whether a variation of the c 1 ⁄ ... likely, as the c ring is rather stable, and the use of Triton X- 100 should not lead to removal of c 1 only.
