The phrase "as second reference" is correct and usable in written English.
It can be used when indicating that something is being cited or referred to as a secondary source or point of reference.
Example: "In the report, I will include the original study as the primary source and the subsequent analysis as a second reference."
Alternatives: "as a secondary reference" or "as an additional reference".
Thus, the weighted LD amplitudes using Yoruba or non-Africans as second references are nearly 2 α βF2(A, B), where B denotes the admixing Bantu population.
Third, our analysis was based on the policies as documented in the online instructions that potential authors would consult as first reference.
The RF1-containing class was then classified further with the RF1-containing map (EMDB ID 1184) as first reference and a second reference ('RF1/RF3-chimera') generated by adding the segmented RF3 density from the RF3GDPNP map (EMDB ID 1302; Gao et al., 2007) to the RF1-containing map (EMDB ID 1184).
These overall reference values might not only be useful in evaluating the single-item reliability of personality measures but might also serve as first reference points for the reliability of single-item measures of other constructs, for example, subdimensions of emotional intelligence or specific values.
However, this curve is present only when using Onge themselves as one reference; moreover, the amplitude is independent of whether CEU, CHB, YRI, GIH (HapMap Gujarati), or Great Andamanese is used as the second reference, as expected if the weighted LD is due to correlation between LD and allele frequencies in the test population alone (and independent of the reference allele frequencies).
The H.264 encoder and decoder are employed in the proposed scheme with the only difference being that an McFIS is used as the second reference frame instead of five previous frames as reference frames.
Imputation was performed based on the 1000G GIANT phase1 panel as a first reference set, and on the GONL version 4 as a second reference set (see Supplementary Methods for details).
That is, the input-forcing function with 90∘ shift in its phase is taken as the second reference.
First, an McFIS is used as the second reference frame in addition to the immediate previous frame.
