A paper by Qian & Wasserburg suggests the optical absorption lines of uranium observed in the spectra of ultra-metal-poor stars (defined as [Fe/H] <-3) arise from contamination from a supernova in a binary star system. Assuming the binary survived the explosion, a collapsed compact object may be present and implying potential accretion processes with accompanying X-ray emission. Upper limits on...

Upper limits on the cross section for Standard-Model Higgs-boson production in p¯ p → H + X at √ s = 1.96 TeV are determined for 100 < mH < 200 GeV/c 2. The contributing processes include associated production (W H → νb ¯ b, ZH → + − /ν ¯ νb ¯ b, and W H → W W + W −) and gluon fusion (H → W + W −). Analyses are conducted with integrated luminosities from 260 pb −1 to 950 pb −1 recorded by the D...

"Upper limits of normal" antistreptolysin O (ASO) and antideoxyribonuclease (ADN) B titers were determined on serum specimens from various age groups of pediatric patients with no history of a recent streptococcal infection and on healthy adult hospital employees. The upper limit of normal value is that level of antibody titer exceeded by no more than 15% of the total subjects in each age group...

GRB 990123 established the existence of prompt optical emission from gamma-ray bursts (GRBs). The Livermore Optical Transient Imaging System (LOTIS) has been conducting a fully automated search for this kind of simultaneous low energy emission from GRBs since October 1996. Although LOTIS has obtained simultaneous, or near simultaneous, coverage of the error boxes obtained with BATSE, IPN, XTE, ...

The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored as gravitational radiation for three d...
