We are researching the interaction between the rule and the ontology layers of the Semantic Web, by comparing two options: 1) using OWL and its rule extension SWRL to develop an integrated ontology/rule language, and 2) layering rules on top of an ontology with RuleML and OWL. Toward this end, we are developing the SWORIER system, which enables efficient(More)
Pregabalin has been shown to have anticonvulsant, analgesic, and anxiolytic activity in animal models. Pregabalin binds with high affinity to the α2δ1 and α2δ2 subunits of voltage-gated calcium channels. In order to better understand the relative contribution that binding to either the α2δ1 or α2δ2 subunits confers on the anticonvulsant activity of(More)
We are developing SWORIER (Semantic Web Ontologies and Rules for Interoperability with Efficient Reasoning), which is a system that uses Logic Programming to reason about ontologies and rules in order to answer queries. The system expects a human developer to create ontologies in the formalisms of OWL-DL (Web Ontology Language for Description Logic) along(More)
Historically, the behavior of Department of Defense (DoD) Command and Control (C2) systems has been embedded in executable code, providing static functionality that is difficult to change. As the complexity and tempo of the world increase, C2 systems must move to a new paradigm that supports the ability to dynamically modify system behavior in complex,(More)

Parental protection of offspring is found in numerous animal species. Protection provides offspring with a greater chance of surviving to be able to reproduce, while at the same time, often posing a cost to the parent. Therefore, the net value of defence for the parent can vary depending on the developmental stage of the offspring and their ability to(More)
Resource availability and location are expected to vary, based on use by individuals and changing ecological conditions; the response of animals to those changes is critical to their fitness. To investigate the effects of changing conditions on fitness, we conducted field experiments using the central-place-foraging alfalfa leafcutting bee (Megachile(More)
