A Note on Covering by Convex Bodies

A classical theorem of Rogers states that for any convex body K in n-dimensional Euclidean space there exists a covering of the space by translates of K with density not exceeding n log n+n log log n+5n. Rogers’ theorem does not say anything about the structure of such a covering. We show that for sufficiently large values of n the same bound can be attained by a covering which is the union of ...

White Paper Application Note

Introduction Short column sedimentation equilibrium analysis offers many advantages for researchers wanting quick, sure characterization of the solution properties of macromolecules. Presented here is a list of when short column methods are an appropriate choice, a brief theoretical treatment and an overview of short column sedimentation methods, including ones diagnostic for self-association a...

White Paper Application Note

Insulin is a well characterized drug used to treat diabetes. A large number of insulin formulations have been investigated in order to develop the optimum time delivery suited to patient needs. In addition, a number of insulin analogs such as Insulin Glargine and LysPro insulin (Humalog) have been developed and marketed as derivatives for immediate use at meal time and a more sustained release....

A Note on the Behavior of the Saprophytic Cocci with Regard to Gram's Stain

C.-E. A., and A. R. Winslow I found that one of the fundamental differences between the parasitic and saprophytic cocci was their behavior to the Gram stain. The parasitic forms (Paracoccace~e) generally retained the stain, while the saprophytic group (Metacoccace~e) generally decolorized by Gram. In my recent revision of the Coccacem in the collection at the Museum of Natural History, 2 I was ...
