Profile of Scott J. Hultgren.

During her lifetime, an adult woman has a 50% chance of developing a urinary tract infection—one of the most common types of infections (1). Most urinary tract infections are caused by strains of the bacterium Escherichia coli, and, for the most part, are easily treated with antibiotics. However, many of these infections become chronic or recurrent because of increasing antibiotic resistance an...

Scott J. Lilley PhD thesis

The AsF6 anion, in the crystalline polymer electrolyte PEO6:LiAsF6, was replaced with the larger N(SO2CF3)2 anion. This produced an increase in the room temperature ionic conductivity of 1.5 orders of magnitude. It is believed that the enhancement is the result of the disruption of the electrostatic field around the lithium ions. The presence of the large and asymmetrical N(SO2CF3)2 ion creates...

Pinnipeds and Carnivores: Phyletic Relationships and Classification J. Scott Shannon

Shannon, J. S. (Department of Wildlife, Humboldt State University, Arcata, California 95521) 1987. Pinnipeds and carnivores: phyletic relationships and classification. Syst. Zool. xx:xxx-xxx. Evidence for monophyly and polyphyly of the pinnipeds is summarized and discussed with reference to the classification of the higher subtaxa of the Pinnipedia and the order Carnivora. On the basis of a con...

J . A . Scott HSL MI 20 : an efficient AMG preconditioner

Algebraic multigrid (AMG) is an efficient multilevel method for solving large sparse linear systems obtained from the discretisation of scalar elliptic partial differential equations. AMG can be used to compute powerful preconditioners for use with Krylov subspace methods. We report on the design and development of an efficient, robust and portable implementation of AMG that is available as pac...
