A relatively low rate of labelling of roots in the non-labelled compartment was found for both 15NO3− (4% of root N) and 15N-glutamine (6% of root N; Fig. 3) when roots were growing in identical N environments.
Average iterations Oversegmentation rate Rate of labelling disjoint regions differently Proposed alg.
The rate of labeling inflow can be controlled by using different cell densities and/or different fractions of the labeled tracer in the feed.
The clustering model of SWKC-GS is defined based on wrong classification rate of labeled samples and fuzzy clustering index on the whole dataset.
With 4 times more blocks, the proposed algorithm demonstrates the same level of performance, in terms of oversegmentation rate and rate of labelling the two dark regions differently, with a slight increase of computational cost compared to Table 1.
Table 1 differently shows the two algorithms' performance in terms of computational cost measured by average iterations, oversegmentation rate, and rate of labelling disjoint regions of the same texture when the image in Figure 3 is divided into 64 blocks.
The precursor concentration increases along the series NaCl-, ethacetoneacetone- and fractionation PP, and is most likely the reason for the increasing rate of labelling along the same series.
At the onset of feeding, the infusion rate of labeled leucine was increased to 0.12 µmol kg body wt−1·min−1 to adjust for the increased plasma leucine availability.
