Biological invasions with known histories are rare, especially in the sea, and empirical studies of the genetic consequences are even rarer. Fifty-five years ago, the state of Hawai'i began a remarkable, if unintentional, 'experiment' with the introduction of three reef fishes, Lutjanus fulvus, Cephalopholis argus and Lutjanus kasmira. All have since expanded from the initial introduction of 22...

The Caribbean spiny lobster Panulirus argus is a valuable fishing resource and the trade in frozen lobster tails is an important industry. However, the presence of the pathogenic virus Panulirus argus Virus 1 (PaV1), which causes systemic infection in P. argus and is particularly lethal to juvenile individuals, has not been previously examined in imported/exported lobster products. We used PCR ...

Accurate age estimates for Panulirus argus, the commercially important Caribbean spiny lobster, would greatly enhance life history and population analyses. Most age approximations of P. argus are based on size and growth data, but size is generally considered a poor proxy for age of crustaceans in the field because of numerous environmental, density-dependent, and fishery-related factors. An es...

This paper describes the ARGUS prototype, a high-density, low-power supercomputer built from an IXIA network analyzer chassis and load modules. The prototype is configured as a diskless distributed system that is scalable to 128 processors in a single 9U chassis. The entire system has a footprint of 0.25 m2 (2.5 ft2), a volume of 0.09 m3 (3.3 ft3) and maximum power consumption of less than 2200...

A fast second level trigger has been developed for the ARGUS experiment which recognizes tracks originating from the interaction region. The processor compares the hits in the ARGUS Micro Vertex Drift Chamber to 245760 masks stored in random access memories. The masks which are fully deened in three dimensions are able to reject tracks originating in the wall of the narrow beampipe of 10.5 mm r...

Low-cost mini-drones with advanced sensing and maneuverability enable a new class of intelligent sensing systems. Œis trend motivated several research e‚orts to employ drones as standalone systems or to assist legacy deployments. However, several fundamental challenges remain unsolved including: 1) Adequate coverage of sizable targets; 2) Target orientation that render coverage e‚ective only fr...

Introduction New Hypothesis formation may be an analyst-initiated activity, an automated process whereby a novel trend is discovered and tracked, or a hybrid one. In the hybrid case, the system offers its discovery of novel, potentially interesting patterns for analyst review, leading to new hypothesis being formed and tracked, or to discarding the novelty as coincidental or uninteresting. The ...
