XAP/1 was a constraint-based planner designed to generate plans for the manufacture of mechanical assemblies. In order to extend it to be able to generate plans utilizing subassemblies the constraint language must be extended. It has been proposed elsewhere that deepest common ancestor relations can form the basis for such a system[1]. This report serves to provide a formal basis for the use of...

Using the remotely operated vehicle Deep Discoverer, we observed a large stylodactylid shrimp resting on a sedimented sea floor at 4826 m in the Marianas Trench Marine National Monument. The shrimp was not collected but most closely resembled Bathystylodactylus bathyalis, known previously only from a single broken specimen. Video footage shows the shrimp facing into the current and extending it...
