Summary: An experiment to increase expiratory muscle strength for instrumentalists, using a high-intensity, low-repetition expiratory training method, was conducted with 40 healthy high school band players. Subjects trained five days [...]

High-energy experiments at the proton-antiproton Collider Detector at Fermilab near Chicago suggest the existence of the top quark of mass 174 plus or minus 10 GeV per c squared. The calculated quark mass should help understand the production of mass of elementary particles. Supersymmetry, which suggests that each particle should have a partner called sparticle, and the Standard Model limit transitions between quarks of the same charge. The large Hadron Collider, to be built at CERN, Geneva, Switzerland, and the Stanford linear Accelerator should provide substantial evidence for the presence of sparticles.

Two experiments designed to measure the spin structure of the neuron yielded varying results. The first experiment conducted by the Spin Muon Collaboration used a target containing frozen, polarized deuterons and yielded an In value of -0.08 +/- 0.06. On the other hand, Stanford scientists used a polarized helium-3 nuclei and yielded an In of -0.022 +/- 0.011. The latter value is more accurate since more data were used in measurement.
