This paper reviews the fate of the central ideas behind the complementary learning systems (CLS) framework as originally articulated in McClelland, McNaughton, and O'Reilly (1995). This framework explains why the brain requires two differentially specialized learning and memory systems, and it nicely specifies their central properties (i.e., the hippocampus(More)
We describe techniques for coordinating the actions of large numbers of small-scale robots to achieve useful large-scale results in surveillance, reconnaissance, hazard detection, and path finding. We exploit the biologically inspired notion of a " virtual pheromone, " implemented using simple transceivers mounted atop each robot. Unlike the chemical(More)
Complementary learning systems (CLS) theory describes how the hippocampal and cortical contributions to recognition memory are a direct result of their architectural and computational specializations. In this paper we model a further refinement of CLS that features separate handling of inputs from the dorsal and ventral posterior cortices, and present a(More)
A Command Entity (CE) is a goal-oriented intelligent agent specifically designed to command and control other agents. The CE niche, most often a military battlefield, is a complex, dynamic, adversarial environment in which a CE must balance the needs for thorough planning with the need for quick reactions to changing conditions. We describe the requirements(More)
(ABSTRACT) Virulent strains of the bovine opportunistic pathogen Haemophilus somnus (Histophilus somni) cause multi-systemic diseases in cattle. One of the reported virulence factors that H. somnus may use to persist in the host is resistance to intracellular killing. It is reported in this dissertation that H. somnus significantly (P <0.001) inhibited(More)
