A person separation index of 2.0 indicates that the sample can be separated into at least three distinct groups [ 35], and an item separation index of 2.0 means that the items can be divided into three distinct levels of ability [ 36].
Pc-G proteins are transcriptional repressors that functionally can be separated into at least two different complexes: the initiation complex, Polycomb complex 2 (PRC2), which in humans consists of EZH2, EED, and SUZ12; and the maintenance complex, PRC1, with the core proteins RNF2, HPC, and BMI1.
Based on the pH in the lumen, the midguts of insects can be separated into at least three compartments (Terra and Ferreira 1994).
Based on a combination of comparative genomics, literature and phylogenetic analyses and experimental validations, the COG0523 family can be separated into at least fifteen subgroups.
There are four Akabane virus genogroups, of which two groups, I and II, are extant in Japan [ 26, 27], whereas the field isolates can be separated into at least five antigenic groups by an immunobinding assay using neutralizing antibodies [ 25].
Arguably the most complex motor behavior displayed by this organism, male mating can be separated into at least six sub-steps: response, backing, turning, vulva location, spicule insertion, and sperm transfer [ 3].
The phylogeny of populations showed that all of the four Malay sub-ethnic groups are separated into at least three different clusters.
Serum was separated into at least four aliquots to avoid repeated freeze-thaw cycles and was stored at -20°C until testing.
Based on nuclear DNA sequence information and a number of phenotypic markers, this fungal complex has been separated into at least 50 species [ 23, 24].
Fugu was not included in this analysis because fugu V2R clusters were separated into at least four unconnected scaffolds and thus we could not identify the gene order around V2R clusters.
We also calculated the properties of the diarsa congener 3a and predicted that it also exhibits axial chirality and that it can be separated into enantiomers at ambient temperature.
