Images on the left side are probe images, and the images on the right are gallery images.
First, to measure the influence of set size in the change perception task on recall accuracy, there are probe present and probe absent trials for Add (5 sounds), No-change (4 sounds), and Remove (3 sounds) trials.
Drugstore chains and supermarkets have underperformed, but Kroger (30, KR), Safeway (52, SWY) and Rite Aid Corp. (25, RAD) are probe positions, meaning you buy a little and then add more if GDP growth slows to a trendline of around 2.5%.
The results have shown that there are 'empty' probe sets detecting transcripts, spiked in at different concentrations, and, reversely, there are probe sets that do not detect transcripts, spiked in at different concentrations, even though they were designed to do so.
(At present the other divisions are Probe International, Environment Probe, the Environmental Bureau of Investigation, and the Consumer Policy Institute, all of which are based out of its red brick headquarters on leafy Brunswick Avenue).
Redundant probe sets are probe sets that measure different regions of the same target gene.
