Researchers in a growing number of areas (including cognitive development, aging, and neuropsychology) use Brinley plots to compare the processing speed of different groups. Ratcliff, Spieler, and McKoon (2000) argued that a Brinley plot is a quantile-quantile (Q-Q) plot and that therefore Brinley plot regression slopes measure standard deviation ratios rather than relative speed of processing....

Choosing a liquid chromatography (LC) column for particular application can be surprisingly challenging task. On the one hand, manufacturers provide us many options to choose from, including particle types, pore sizes, and different lengths diameters. other we usually do not have time experimentally evaluate combinations of these parameters, sometimes end up picking something similar columns th...
