We consider a distributed system where sensors make location parameter estimates using their observations. A central processor collects the local estimates and declares a nal estimate based on them. We present a simple study of the convergence properties of three structures where empirical mean and M-estimates are used in various combinations. It is shown that when occasional outliers exist, de...

In clinical therapy trials using high dosages of systemically administered radioactivity to treat cancer, myeloablation may occur. This is either an effect of the circulating radioactivity labeled to antibodies exposing the bone marrow to radiation, or it may occur because malignant cells in the bone marrow are targeted. Bone marrow cells may be targeted through antigens expressed on cells in t...

E. coli O157:H7 is an emerging food and waterborne pathogen. The development of acceptable guidelines for exposure to this organism based on quantitative microbial risk assessment requires a dose response curve. In this study, a prior animal study was used to develop a dose response relationship. The data was adequately fit by the beta-Poisson dose response relationship. This relationship was v...
