ABSTRACT
Scott and White is the largest integrated healthcare delivery system in the Southwest. The rapid and continual expansion of readily available patient-related computerized information from multiple sources and systems within our enterprise over the last ten years has now enabled our development of a user-friendly, yet secure, access module to meet our clinicians' point-of-care information needs. We have developed and begun implementation of these individualized "Personal Information Webs". Each clinician is provided, with rigorous security and confidentiality measures built in, a personal web portal to our enterprise intranet. This page has predetermined navigational parameters and functionalities that are based on a rigorous role-based user security profile model. The portal provides its owner bi-directional communication with our back-end enterprise business and clinical information resources by communicating with them at a "virtual XML document" level, using a personal information broker/server as an intermediary.
ABSTRACT
Milagrito, a detector sensitive to very high energy gamma rays, monitored the northern sky from 1997 February through 1998 May. With a large field of view and a high duty cycle, this instrument was well suited to perform a search for TeV gamma-ray bursts (GRBs). We report on a search made for TeV counterparts to GRBs observed by BATSE. BATSE detected 54 GRBs within the field of view of Milagrito during this period. An excess of events coincident in time and space with one of these bursts, GRB 970417a, was observed by Milagrito. The excess has a chance probability of 2.8x10-5 of being a fluctuation of the background. The probability for observing an excess at least this large from any of the 54 bursts is 1.5x10-3. No significant correlations were detected from the other bursts.
ABSTRACT
The Milagrito water Cerenkov detector near Los Alamos, New Mexico, was operated as a sky monitor at energies of a few TeV between 1997 February and 1998 May, including the period of the strong, long-lasting 1997 flare of Markarian 501. Milagrito served as a test run for the full Milagro detector. An event excess with a significance of 3.7 sigma from Markarian 501 was observed, in agreement with expectations.
