small samples. These tests can be implemented efficiently, and have been used for the detection of composite terms and for the determination of domain-specific terms. In some cases, these measures perform much better than the methods previously used. In cases where traditional contingency table methods

Cosmic microwave anisotropy satellites promise extremely accurate measures of the amplitude of perturbations in the universe. We use a numerical code to test the accuracy of existing approximate expressions for the amplitude of perturbations produced by single-field inflation models. We find

Summary. Human semen contains glucose which can be determined by means of glucose oxidase, provided that certain strict analytical pre-cautions are observed. Glucose occurred in all but two of 185 samples. The mean concentration was 7\m=.\24mg/100 ml (s.e.m. \m=+-\0\m=.\69;range 0 to 99).

Accurate determination of optimal reflux policies for the maximum distillate problem in batch distillation

The Solar Diameter Monitor measured the duration of solar meridian transits during the 6 years 1981 to 1987, spanning the declining half of solar cycle 21. We have combined these photoelectric measurements with models of the solar limb-darkening function, deriving a mean value for the solar near-equatorial radius of 695.508 ±.026 Mm. Annual averages of the radius are identical within the measurement error of ±.037 Mm. Subject headings: Sun: diameter, helioseismology

novel sensor system, suitable for large-scale deployment in indoor environments, which allows the locations of people and equipment to be accurately determined. We also describe some of the context-aware applications that might make use of this fine-grained location information.

equation for a propagating level set function, and use techniques borrowed from hyperbolic conservation laws. Topological changes, corner and cusp development, and accurate determination of geometric properties such as curvature and normal direction are naturally obtained in this setting. In this paper, we

more accurate age determination may come from passively evolving high-redshift ellipticals. In particular, I will review two new methods to determine the age of GC. These two methods are more accurate than the classical isochrone fitting technique. The first method is based on the morphology

Linezolid showed MIC50s and MIC90s of 1g/ml (for both) against Staphylococcus aureus. Two S. aureus strains exhibited higher MICs (4 to 8g/ml) caused by cfr and/or target site mutations, including the first detection of cfr in Poland. Linezolid (MIC50 andMIC90, 0.5 and 1g/ml) had potent MICs against coagulase-negative staphylococci (CoNS). Four CoNS hadMICs of 16 to 128g/ml due to alterations in 23S rRNA and/or L3/L4. Linezolid inhibited all enterococci and streptococci at<2g/ml, except for one Enterococcus faecium strain (MIC, 8 g/ml; G2576T [Escherichia coli numbering] mutation). The oxazolidinone linezolid has been clinically available fornearly 15 years (approved by the Food and Drug Administra-tion in April 2000) and has become an important agent in the antimicrobial armamentarium against Gram-positive organisms. Linezolid represents one of the few options approved by the reg-ulatory agencies for treatment of infections caused by vancomy-cin-resistant Enterococcus faecium and Enterococcus faecalis and is the only orally developed alternative (1, 2). Other approved indi-cations for linezolid are the treatment of nosocomial and commu-nity-acquired pneumonia and uncomplicated and complicated (including diabetic foot infections) skin and skin-structure infec-tions (1). The spectrum and activity of linezolid has been monitored

We give a simple method to calculate without approximation the balanced density field of an axisymmetric vortex in a compressible atmosphere in various coordinate systems given the tangential wind speed as a function of radius and height and the vertical density profile at large radius. The method is generally applicable, but the example considered is relevant to tropical cyclones. The exact solution is used to investigate the accuracy of making the anelastic approximation in a tropical cyclone, i.e. the neglect of the radial variation of density when calculating the gradient wind. We show that the core of a baroclinic vortex with tangential wind speed decreasing with height is positively buoyant in terms of density differences compared at constant height, but at some levels may be interpreted as cold-cored or warm-cored depending on the surfaces along which the temperature deviation is measured. However, it is everywhere warm-cored if the potential temperature deviation is considered. In contrast, a barotropic vortex in a stably-stratified atmosphere is cold-cored at all levels when viewed in terms of the temperature deviation at constant height or constant σ, but warm-cored when viewed in terms of the potential temperature deviation along these surfaces. The calculations provide a possible explanation for the observed reduction in surface air temperature in the inner core of tropical cyclones. 1.
