Geometric area of background aperture.
For example, one algorithm searches for small clusters of identical pixels in an image, and so might reveal where an area of background has been copied and pasted over a blemish.
r values were normalized from 0 to R = 1, and pixel intensity values of each image were normalized by the darkest point in each particle's centre (0) and an average intensity of a random area of background ultrathin carbon film (1).
The FRAP analysis included the determination of the average fluorescence intensity of a region of interest containing an unbleached granule as well as an area of background fluorescence.
The ratio of nucleus to cytoplasm in tubules was calculated as the area of hematoxylin (nucleus staining) divided by the area of background staining (cytoplasmic staining) in five to ten fields of renal cortex per mouse.
The circle selection tool was used to select and measure the "mean gray value" for the area immediately surrounding the single YFP spot, as well as for an area of background.
This form asks them to not only give some basic details of their current event chosen, but also to suggest some areas of background research they will need to conduct and postulate what they think their thesis statement might argue: whether or not their event will be covered in history textbooks.
This statistic and thousands of others are available at StateMaster, a web site that provides detailed comparative state statistics in the areas of background, crime, economy, education, energy, geography, government, health, housing, identification, immigration, industry, labor, lifestyle, military, people, presidential elections, sports, trade, and transportation.
The original set contained 21 information categories within the areas of background data, medical conditions, previous diseases, lifestyle factors, physical examination and laboratory tests.
Tissue sections were imaged using a ScanScope digital scanner (Aperio, Oxford, UK), regions of interest identified for analysis to exclude areas of background staining or poor sample quality, and the mean vessel density (MVD) per mm was assessed using the microvessel analysis algorithm running under ImageScope (Aperio).
To return the effective area of a background associated with a data set, the background ID must be specified along with the data set ID. Here, the effective area array of the first background loaded for data set 1 is returned by get_specresp.
