The Staphylococcus aureus lrgAB operon was recently shown to inhibit extracellular murein hydrolase activity and increase tolerance to penicillin. Further characterization of this operon could provide novel insight into the dynamics of ...

Competency standards are important to school psychology training, and this study demonstrates, in the area of individual intelligence test administration, how competency standards can be implemented. The study sets up behavioral objecti...

Two stochastic population models, a birth-and-death model and a stochastic difference equation model, are compared, using data for a giant-Canada-goose population. The quasistationary probability distribution predicted by the stochastic...

This paper contains some general existence theorems for critical points of a continuously differentiable functional I on a real Banach space. The strongest results are for the case in which I is even. Applications are given to partial d...

Sieber has described a model of PCF consisting of continuous functions that are invariant under certain (finitary) logical relations, and shown that it is fully abstract for closed terms of up to third-order types. We show that one may ...

For the construction of composite surfaces interpolating a given curve net a new local twist estimator was proposed recently (Farin and Hagen, Discount Ghd Eclipse 1992). Some properties of this estimator—including an explicit represe...

Thirty-seven patients with dorsal wrist ganglia underwent arthroscopic resection. The mean follow-up was 20 months, and no complications were encountered. The ganglia were classified into three types according to their arthroscopic appe...

Filter samples of the Southwestern Desert aerosol were analyzed for sulfur using proton induced X-ray emission. These samples were obtained during the winter of 1976–1977 when a series of Great Basin Highs dominated the synoptic weath...

A semigroup S is called a regular band if the laws xx = x and xyxzx = xyzx hold in S. For all subvarieties of the variety of regular bands a set-theoretic description of the free algebra is given. Moreover, it is proved that for fixed s...

The balance of CD4+ and CD8+ T cells in humans is controlled by a major autosomal gene. Here, Alberto Amadori and colleagues propose that in view of the high CD4+ cell turnover during HIV infection, individuals genetically predisposed t...
