Physically clustered VRs may therefore act as "units" of variation, with constituent receptor genes sharing characteristics of SNP accumulation or resistance.
Single-unit activity is irregular; the mean of the single unit coefficients of variation of the interspike intervals is >0.8.
For instance, measurements taken across experimental units over time are influenced by 'between time' and 'between unit' components of variation.
The study, co-authored by Stanley J. Ulijaszek, director of the Unit of Biocultural Variation and Obesity at the Institute of Social and Cultural Anthropology at the University of Oxford, and Emily E. Ventura, a research associate at the Childhood Obesity Research Center at U.S.C., was scheduled for publication Tuesday in the journal Global Public Health.
Although preliminary analysis examined data from each year or round, these were pooled for the final analysis and survey round was treated as the unit of temporal variation.
However, the fundamental unit of heritable variation in transcript abundance is the underlying regulatory allele, and as a result it is necessary to understand gene expression evolution at the level of DNA sequence variation.
Standard errors were calculated from the model, with replicate as the unit of sampling variation, using a least-square means approach.
As a unit of annual variations we selected the month (M) equal to T/12, where T = 365.25 days is the solar year (YS).
Inaccuracy can result from lack of measurements, unit-to-unit variation, and variation during normal operation.
For each CpG unit, a coefficient of variation (CV = standard deviation (SD)/mean) of the MI in 10 placentas was calculated (Figure 3 and Table S8).
