Four Papers by the Supernova Cosmology Project

Description: Our search for high-redshift Type Ia supernovae discovered, in its first years, a sample of seven supernovae. Using a 'batch' search strategy, almost all were discovered before maximum light and were observed over the peak of their light curves. The spectra and light curves indicate that almost all were Type Ia supernovae at redshifts z = 0.35 - 0.5. These high-redshift supernovae can provide a distance indicator and 'standard clock' to study the cosmological parameters q{sub 0}, {Lambda}, {Ome… more

Progress Report on the g-2 Storage Ring Magnet System

Description: The 3.1 GeV muon storage ring for the g-2 experiment at Brookhaven National Laboratory has three large solenoid magnets that form a continuous 1.451 tesla storage ring dipole with an average beam bend radius of 7.1 meters. In addition to the three storage ring solenoids, there is an inflector dipole with nested dipole coils that create very little stray magnetic field. A superconducting shield on the inflector gets rid of most of the remaining stray flux. This paper reports on the progress made… more

Mammary gland tumor formation in transgenic mice overexpressing stromelysin-1

Description: An intact basement membrane (BM) is essential for the proper function, differentiation and morphology of many epithelial cells. The disruption or loss of this BM occurs during normal development as well as in the disease state. To examine the importance of BM during mammary gland development in vivo, we generated transgenic mice that inappropriately express autoactivating isoforms of the matrix metalloproteinase stromelysin-1. The mammary glands from these mice are both functionally and morphol… more

Interaction of fast waves with ions

Description: To fully utilize the available power sources in DIII-D (FW, NBI, ECH), understanding of the synergism between the heating mechanisms is important. In this paper the ion distribution, under simultaneous application of NBI and FW, is calculated from Fokker-Planck code CQL3D coupled to ray-tracing code CURRAY. It is found that interaction between energetic ions and FW can be minimized or maximized by adjusting various parameters such as magnetic field, density, beam energy, and FW frequency. Speci… more

Controlling cycle-by-cycle variation in a pulse combustor

Description: We describe a method for controlling chaos-generated cyclic variations in a pulse combustor. The method is applied to a recently developed thermal pulse combustor model and utilizes a map-based, adaptive proportional feedback algorithm. With this technique we show that it is possible to greatly reduce cycle-by-cycle pulse variation. We further show that minimizing cyclic variation allows combustor operation at conditions well beyond the normal flameout limit.

Ceramic composites with a ductile Ni{sub 3}Al binder phase

Description: Composites using B-doped ductile Ni{sub 3}Al alloys were produced with both non-oxide (WC, TiC) and oxide (Al{sub 2}0{sub 3}) ceramic powders. Typical powder processing techniques were used to fabricate materials with ceramic contents from 0-95 vol. %. The microstructural morphology of the composites depends primarily on the wetting behavior between the alloys and the ceramic powders. The non-oxide ceramic powders wet well and the Ni{sub 3}Al alloys form a semi-continuous intergranular phase. O… more
