A survey of 17 fishes belonging to 11 species from Grand Cayman, Cayman Islands, West Indies, led to the recovery of 2 species of acanthocephalans and 9 of digeneans. The acanthocephalans found were Acanthogyrus (Acanthosentis) acanthuri and Dollfusentis ctenorhynchus. The digeneans included Monorchimacradena acanthuri in Acanthurus bahianus (new host record), Bucephalus varicus, Hurleytrematoi...
This paper deals with the computation of robust iris templates from video sequences. The main contribution is to propose (i) optimal tracking and robust detection of the pupil, (ii) smart selection of iris images to be enrolled, and (iii) multi-thread and quality-driven decomposition of tasks to reach real-time processing. The evaluation of the system was done on the Multiple Biometric Grand Ch...
The impressive results of the 2007 DARPA Urban Challenge showed that fully autonomous vehicles are technologically feasible with current intelligent vehicle hardware. It is natural to ask how current transportation infrastructure can be improved when most vehicles are driven autonomously in the future. Dresner and Stone proposed a new intersection control mechanism called Autonomous Intersectio...
The DARPA Urban Challenge required robotic vehicles to travel more than 90 km through an urban environment without human intervention and included situations such as stop intersections, traffic merges, parking, and roadblocks. Team VictorTango separated the problem into three parts: base vehicle, perception, and planning. A Ford Escape outfitted with a custom drive-by-wire system and computers ...
The late Cenozoic geomorphic evolution of Grand Canyon has been infl uenced by three primary tectonic and drainage adjustment events. First, 1 km of relief was produced along the Grand Wash–Wheeler Fault system beginning at 16.5 Ma. Second, the ancestral Colorado River became integrated with the lower Colorado River through Grand Canyon between 5.5 and 6 Ma. Third, the Colorado River was infl u...
Previous studies have shown that indigenous beetle diversity reflects indigenous plant diversity in modified and remnant habitats. This study examines the indigenous: introduced relationship at a locality where degraded pasture has been progressively revegetated. Pitfall traps were used to collect beetles from three revegetated sites of different ages (5, 17 and 100 years) and in a coastal Mueh...
By means of a Q-banding technique, virtually every chromosome in two heteroploid mouse cell lines, RAG and MSWBS, has been identified. The origin of 60 to 80% of the chromosomes has been established; the remaining chromo somes can be identified as markers characteristic of the cell line. The extent of chromosome heterogeneity has been ex amined and compared in these two mouse tumor cell lines. ...
WHAT THIS ARTICLE IS ABOUT The subtribe Flaveriinae (Asteraceae: Helenieae) includes a number of plant species sometimes called yellowtops, glowworts, and false broomweed. Different species of this subtribe differ in their chemical pathways involved in photosynthesis. Somes species use a system known as C 3 photosynthesis, some use a system known as C 4 photosynthesis, and others display charac...
Gene flow and potential for Sin Nombre virus (SNV) trafficking of the deer mouse (Peromyscus maniculatus) was studied in Delta and Mesa counties of western Colorado (USA). The study areas included Grand Mesa and surrounding grazing and agricultural areas. This area has several natural potential barriers to rodent gene flow, including rivers, cliffs, and mountains. Ten study sites were utilized ...
