We report 60 and 90 m observations of seven millisecond pulsars with the Infrared Space Observatory. The pulsar PSR B1257+12 is orbited by three planets, and other millisecond pulsars may be orbited by dust disks that represent planets that failed to form or their residue. We do not detect any infrared emission from the seven pulsars in our sample, and typical upper limits are 100 mJy. Using a ...

In this paper, we show that for an almost locally separable metrizable space X, if its Wijsman hyperspace induced by one compatible metric is Baire, then X itself must be Baire. We also provide an example to demonstrate the necessity of separability.

OBJECTIVES We sought to examine the associations between participation in a worksite fitness center and worker productivity. METHODS A modified Work Limitations Questionnaire (WLQ) and employees' short-term disability claims were used as productivity measures with multivariate logistic regression models to control for health risk, age, gender, and work location. RESULTS Nonparticipants in a...
