Sentence examples for differentiated backgrounds from inspiring English sources
Interestingly, a recent scan of differentiation in an invasive marine invertebrate, the gastropod Crepidula fornicata, identified differentiated backgrounds characterized by a high rate of outliers in the native range of the species in America, but only one background was proved to have invaded Europe, and no outliers have been identified in the invaded range (Riquet et al. 2013).
Additionally, in the case of introductions, the time lag can appear too short at first sight to suggest the existence of a genome-wide multifactorial, semipermeable genetic barrier to gene flow, but multiple introductions could well have imported differentiated backgrounds from the area of origin to the invaded zone.
Using three large-scale experiments (N1 = 101, N2 = 84, N3 = 176) we find that displaying advertisement and content results with a differentiated background results in significantly lower click rates.
This is because there is a poor correlation between signal intensity and target concentration at the low end [16], and because the signal obtained from these targets can't be differentiated from background noise in the low concentration milieu [22].
Positive staining was differentiated from background by thresholding the image according to hue in order to create a mask.
This suggests that this and similar markers will be useful in a real-time PCR methodology where positive signals can be more readily differentiated from background signals [ 15].
Positive PD-L1 staining is defined as complete and/or partial circumferential linear plasma membrane staining at any intensity that can be differentiated from background and diffuse cytoplasmic staining.
Because individual benzene exposures were obtained for both exposed and control workers, we constructed exposure adduct relationships over about 5 orders of magnitude of air concentrations and determined levels of exposure at which benzene-derived adducts can be differentiated from background adducts.
Thus, we speculate that since the down-regulation of CDKN1A and GDF15 is not as efficient as tRNA genes after Pol III knockdown, the amount of Pol III binding at CDKN1A and GDF15 prior to MAF1 knockdown may be too low to be differentiated from background (MAF1/Pol III knockdown).
The use of highly differentiated host genetic backgrounds, for instance the introduction of different resistant R gene pyramids through ad-hoc cassettes in a cisgenesis transformation process (Haverkort et al. 2008), might help, although the durability of gene pyramids has proven low in the past due to the large effective population sizes of the pathogen (e.g., Andrivon 1994).
So I wrote a paper on background subtraction algorithms — how to find a foreground object differentiated from the background — and applied those algorithms to my baby.
