We describe the second order obstruction to deformation for nearly G 2 structures on compact manifolds. Building work of Alexandrov and Semmelmann, this allows proving rigidity under proper structure Aloff–Wallach space N ( 1 , ) .

objective: the effects of natural adjuvants were examined on total and differential wbc counts in lung lavage of sensitized guinea pigs. materials and methods: in three sensitized groups of guinea pigs including: untreated sensitized animals (s), sensitized animals treated with adjuvant g2 (s+g2) and g2f (s+g2f) as well as non-sensitized group (c) (n=6 for each group), total and differential wb...

Let G and H be graphs. A graph with colored edges is said to be monochromatic if all its edges have the same color and rainbow if no two of its edges have the same color. Given two bipartite graphs G1 and G2, the bipartite rainbow ramsey number BRR(G1; G2) is the smallest integer N such that any coloring of the edges of KN;N with any number of colors contains a monochromatic copy of G1 or a rai...

We present a model independent closed form expression for |Vub| /|VtbV ∗ ts| 2, which includes the resummation of large endpoint logarithms as well as the interference effects from the operators O2 and O8. We demonstrate that the method to extract |Vub| presented by the authors in hep-ph/9909404, and modified in this letter to include interference effects, is not just a refinement of the method...
