The evidence for the low mass J = 0 states is reconsidered. We suggest classifying the isoscalars f0(980) and f0(1500) as members of the 0 ++ nonet, with a mixing rather similar to that of the pseudoscalars η′ and η. The broad state called f0(400− 1200) or “sigma” and the state f0(1370) are considered as different signals from a single broad resonance, which we take to be the lowest-lying 0 glu...

The phenomenological framework outlined in the companion paper [C. A. Shera and G. Zweig, J. Acoust. Soc. Am. 92, 1356-1370 (1992)] characterizes both forward and reverse transmission through the middle ear. This paper illustrates its use in the analysis of noninvasive measurements of middle-ear and cochlear mechanics. A cochlear scattering framework is developed for the analysis of combination...

Scalar-isoscalar mesons are studied using an unitary model in three channels: ππ, KK and an effective 2π2π. All the solutions, fitted to the ππ and KK data, exhibit a wide f0(500), a narrow f0(980) and two relatively narrow resonances, lying on different sheets between 1300 MeV and 1500 MeV. These latter states are similar to the f0(1370) and f0(1500) seen in experiments at CERN. Branching rati...

According to the QCD expectations the lightest glueball should be a scalar particle (J = 0). Different scenarios have been considered for a classification of these states but – despite considerable progress in recent years – the experimental basis for various parameters is still rather weak. We present a new analysis of the elastic and charge exchange ππ scattering between 1000 and 1800 MeV. A ...

The baby was born at 27 weeks gestation to a 31year-old mother by normal vaginal delivery. Birth weight was 1370 grams and Apgar scores were 9 at one minute and 10 at five minutes. He was admitted to the neonatal intensive care unit for respiratory distress syndrome requiring continuous positive airway pressure (CPAP) support. On the second day of hospital stay, although the general condition o...

Glacial polish, grooves, and striations discovered at an elevation of 1370 meters in the headwaters of Boone Fork on Grandfather Mountain, North Carolina, indicate the former, existence of alpine glaciation at a latitude of 36 degrees 07'N. The Boone Fork glacier was located 890 kilometers south of the previously recognized southern limit of alpine glaciation in the Appalachian Mountains, and 3...
