Concentric-tube robots can offer dexterous positioning even in a small constrained environment. This technology turns out to be beneficial in many classes of minimally invasive procedures. However, one of the barriers to the practical use of a concentric-tube robot is the design of a real-time control scheme. In previous work by the authors, a(More)
The effects of carvacrol, a natural biocide, on dual-species biofilms formed by Staphylococcus aureus and Salmonella enterica serovar Typhimurium were investigated with a constant-depth film fermentor. Biofilm development reached a quasi-steady state in 12 days at 25 degrees C with S. aureus predominance ( approximately 99%). Cryosectional analysis detected(More)
Anthrax toxin receptor 1/tumor endothelial marker 8 (Antxr1 or TEM8) is up-regulated in tumor vasculature and serves as a receptor for anthrax toxin, but its physiologic function is unclear. The objective of this study was to evaluate the role of Antxr1 in arteriogenesis. The role of Antxr1 in arteriogenesis was tested by measuring gene expression and(More)
Radiocesium ('34Cs and '37Cs) concentrations were measured in soil, plant and wildlife samples from subarctic to arctic Alaska. Concentrations of 13'Cs ranged from below detectable or low levels in whale and fish samples to as high as 242 Bqkg in lichen. For all potential human food items, the radiocesium concentrations measured in this study were below(More)
Table 2. Summary of the mean concentrations (ng/g THg, % Fe, and g/g rest of the metals) and related statistics for the sediment trace metals (values normalized to Fe) by regions and year of sampling.. Table 3. Time-interval differences in the mean concentrations of trace metals [not normalized to iron (Fe)] in Table 6. Correlations between environmental(More)
Minimally invasive surgery prevents surgeons from manually palpating organs to locate subsurface tumors and other structures. One solution is to use ultrasound; however, it is not always reliable. Various minimally invasive surgery instruments that provide tactile feedback have been proposed to augment ultrasound sensing for tumor localization; however,(More)
