A method of testing for bacteriuria with multiple reagent strips for blood, nitrite, and leucocyte esterase was evaluated. Of 669 urine specimens tested, 267 were negative on the reagent strips and so would ordinarily be discarded, creating a reduction in the workload of culturing urine specimens of 40%. Thirteen of these were false negative results, however, which represented 10% of all the sa...

In this paper, we solve explicitly the optimal stopping problem with random discounting and an additive functional as cost of observations for a regular linear diffusion. We also extend the results to the class of one-sided regular Feller processes. This generalizes the result of Beibel and Lerche [Statist. Sinica 7 (1997) 93–108] and [Teor. Veroyatn. Primen. 45 (2000) 657–669] and Irles and Pa...

Volume 82, Number 6 www.aafp.org/afp American Family Physician 669 A 16-year-old girl presented with fatigue, weight loss, and dysphagia that began several months earlier. She had restless sleep leading to daytime somnolence and poor school performance, and her family reported loud snoring. Her medical history was unremarkable, except for recurrent upper respiratory tract infections. Physical e...

This paper discusses the problem of constructing a locally optimal mesh for the best L2 approximation of a given function by discontinuous piecewise polynomials. In the one-dimensional case, it is shown that, under certain assumptions on the approximated function, Baines’ algorithm [M. J. Baines, Math. Comp., 62 (1994), pp. 645-669] for piecewise linear or piecewise constant polynomials produce...

We calculate the leading order anomalous dimension of the transversity structure function directly using three different methods, the local light–cone expansion in the forward case, the non–forward case, and the short–distance expansion of the forward Compton amplitude. Our results agree with the original calculation by Artru and Mekhfi [Z. Phys. 45 (1990) 669], which has been doubted recently....

Cells of the gliding bacterium Flavobacterium johnsoniae move rapidly over surfaces by an unknown mechanism. Transposon insertions in sprB resulted in cells that were defective in gliding. SprB is a highly repetitive 669-kDa cell surface protein, and antibodies against SprB inhibited the motility of wild-type cells. Polystyrene microspheres coated with antibodies against SprB attached to and we...
