Austrian, Robert (The University of Pennsylvania School of Medicine, Philadelphia), and Patricia Collins. Importance of carbon dioxide in the isolation of pneumococci. J. Bacteriol. 92:1281-1284. 1966.-Of the strains of pneumococci isolated from man, 8% manifest a requirement for CO(2) if detectable growth is to occur on the surface of solid media. The pneumococci most frequently manifesting th...

It is well known that standard estimators of an AR(p) model are biased in finite samples, yet little is done in practice to remove the bias. Apparently small biases have important implications for the estimation of the impulse response function, which is a nonlinear function of the original coefficients. This note shows how to obtain estimators adjusted for first order bias based on Stine and S...

We report results from simultaneous RossiXTE and BeppoSAX observations of the neutron-star x-ray binary and type I X–ray burster 4U 1728-34. The source was found in a high luminosity state, LX ∼ 0.1LEdd, and quasiperiodic oscillations were detected at 1284±6 Hz, the highest frequency ever observed from this source. The x-ray spectrum shows a broad, FWHM ∼ 0.8 keV, iron Kα fluorescence line. We ...

Michel Kerszberg Institut Pasteur CNRS (URA 1284) Neurobiologie Moleculaire 25, Rue du Dr. Roux 75015 Paris, France Based on precise anatomical data of the bee's olfactory system, we propose an investigation of the possible mechanisms of modulation and control between the two levels of olfactory information processing: the antennallobe glomeruli and the mushroom bodies. We use simplified neuron...
