Vicia is a large genus, with ca 150 known species, within a large and important family, the Leguminosae. It is largely an Old World genus with its main centre of diversity in the eastern Mediterranean/western Asia area; there are also 27 known Vicia species in the New World. No Vicia species are on the IUCN “Red List” although several species are threatened within parts of their range raising...
The application of evolving projection analysis (EPA) to second-order bilinear data sets consisting of more than two components is described. EPA is a method for rank analysis of ordered data matrices where the components appear sequentially as a function of time or some other ordinal variable. It was found that extension of the method to mixtures of more than two components was best accomplished...
A mathematical method for detecting spectral impurities in liquid chromatographic peaks measured with a diode array detector (LC-DAD) is described. The new method compensates for certain measurement non-idealities, minimizing the likelihood of a false indication of an impurity. The algorithm, evolving projection analysis, is based on a previously reported method in which points in an n-dimensional...
