Like PER for sucrose, SER allows, therefore, direct quantification of response thresholds to a stimulus that, in this case, is fully independent of a foraging context.
The Tier 1 tests were focused on sensitively detecting the potential to cause effects, rather than accurate quantification of hazard thresholds.
The quantification of groundwater depth thresholds is likely to be critical for management aimed at conserving groundwater dependent biodiversity.
The quantification of such a threshold, an objective with firm biologic plausibility, will dictate the mandate to apply or withhold artificial extracorporeal support.
CMV viremia was measured in whole blood using a CMV DNA real time quantitative PCR [ 9] with results expressed in number of copies/mL (limit of quantification: 1000 copies/mL, threshold of detection close to 100 copies/mL).
Knowledge gaps identified in discussions during the symposium include: identifying questions that can be usefully addressed within a framework emphasizing connectivity; identifying feedbacks that enhance and limit connectivity; and quantification – of diverse aspects of connectivity, of thresholds of connectivity, and of interactions among different types of connectivity.
Based on the quantification of image contrast and threshold, the overall porosity measured in a panoramic area of 2 mm × 2 mm was much more reproducible than that of MIP, and was in agreement with the result of Archimedean.
To allow for quantification of artifacts, we developed threshold values that allowed for measuring the volumes affected by PHV-induced artifacts.
Similarly to H&E-stained tissue sections, MTB-stained tissue slides were scanned using an Aperio digital microscope, and high-resolution images were exported into JMicroVision for quantification of collagen content by thresholding the blue-stained collagen and calculating the percentage of collagen per whole tissue section.
Estimates of risk summarized the high degree of variability experienced in natural systems, the difficulty of predicting fire behavior when conditions are near critical thresholds, a quantification of uncertainties concerning future weather conditions, and useful tool for assessing potential wildfire effects.
