The binding sites for four monoclonal antibodies, rho 1D4, rho 3C2, rho 3A6, and rho 1C5, have been localized within the C-terminal region of bovine rhodopsin: Asp18'-Glu-Ala16'-Ser-Thr-Thr-Val12'-Ser-Lys-Thr-Gl u8'-Thr-Ser-Gln-Val4'-Ala-Pr o -Ala1'. Antibody binding sites were localized by using synthetic C-terminal peptides in conjunction with solid-phase(More)
Four monoclonal antibodies obtained from the fusion of mouse myeloma cells with lymphocytes of mice immunized with bovine rod outer segment disc membranes were shown to bind to the surface of sealed discs. Radioimmune labeling of rod outer segment membrane proteins separated by sodium dodecyl sulfate gel electrophoresis indicated that two monoclonal(More)
The ability to organize agents into abstract groups provides a powerful tool for agent organization and communication in large multi-agent systems. In this paper we outline the fundamental characteristics required of a robust and scalable agent grouping mechanism. These characteristics are then discussed in the context of the Cougaar community(More)
Ferromagnetic iron dextran particles were prepared by reacting a mixture of ferrous chloride and ferric chloride with dextran polymers under alkaline conditions. Particles purified by gel filtration chromatography were in the size range of 30-40 nm, had an electron dense core of about 15 nm, were stable against aggregation in physiological buffer, showed(More)
The days of specifying missions for mobile robots using traditional programming languages such as C++ and LISP are coming to an end. The need to support operators lacking programming skills coupled with the increasing diversity of robot run-time operating systems is moving the eld towards high-level robot programming toolsets which allow graphical mission(More)
Georgia Tech won the O ce Cleanup Event at the 1994 AAAI Mobile Robot Competition with a multi-robot cooperating team. This paper describes the design and implementation of these reactive trash-collecting robots, including details of multiagent cooperation, color vision for the detection of perceptual object classes, temporal sequencing of behaviors for(More)
