The present study was designed to investigate whether absolute work rate (WR) affects Phase I pulmonary oxygen uptake (Vo(2)(p)) duration during moderate-intensity (Mod) exercise and to compare two methods for estimating Phase I Vo(2)(p) duration (P(I-Dur)). Fourteen males (24 ± 5 yr) each completed 4-8 repetitions of Mod transitions from 20 W to 50, 70, 90, 110, and 130 W. P(I-Dur) was identif...

OBJECTIVES/HYPOTHESIS To analyze cost and compare cholesteatoma recidivism and hearing outcomes with single-stage and second-look operative strategies. STUDY DESIGN Retrospective review and cost analysis. METHODS Adult and pediatric patients who underwent a tympanoplasty with mastoidectomy for cholesteatoma with a single-stage or second-look operative strategy were identified. Variables inc...

In this retrospective chart review we compared the subjective and objective benefits of active middle ear implants (AMEIs) with conventional hearing aids (HAs) in patients with sloping high tone hearing loss. Thirty-four patients with sensorineural hearing loss were treated with AMEIs. Of these, six had sloping high tone hearing loss and had worn an HA for more than 6 months. Objective assessme...

Previous studies have shown that a metabolic alkalosis develops in the muscle during early exercise. This has been linked to phosphocreatine hydrolysis. Over a similar time frame, the femoral vein blood pH and plasma K(+) and HCO(-)(3) concentrations increase without an increase in PCO(2). Thus CO(2) from aerobic metabolism is converted to HCO(-)(3) rather than being eliminated by the lungs. Th...

Wolf-Rayet stars (WR) have been detected in the NW region of the metal–poor starburst galaxy IZw 18. The integrated luminosity and FWHM of the bumps at 4650Å and 5808Å are consistent with the presence of a few individual stars of WC4 or WC5 type. Evolutionary synthesis models predict few WRs in this galaxy, but only of WN type. The presence of WC stars at such low metallicity could however be e...

This article presents the design and implementation of a controller scheme for efficient resource management in Advanced Life Support Systems. In the proposed approach, a switching hybrid system model is used to represent the dynamics of the system components and their interactions. The operational specifications for the controller are represented by utility functions, and the corresponding res...

Plover is an automated property-verifier for Haskell programs that has been under development for the past three years as a component of the Programatica project. In Programatica, predicate definitions and property assertions written in P-logic, a programming logic for Haskell, can be embedded in the text of a Haskell program module. P-logic properties refine the type system of Haskell but cann...

In this paper we discuss and compare abstract machines for the lambda-calculus, implementing various evaluation strategies. Starting from the well-known Categorical abstract machine (CAM) and Krivine’s abstract machine (KAM), we develop two families of machines that differ in the way they treat environments. The first family is inspired by the work on closed reduction strategies, whereas the se...
