In this context, two or more abstract links, which use the same physical links, may have correlated latencies [3], bandwidth usage [4], or geographical failures [5, 6].
Natural feed was more beneficial to health of the gills, which may have correlated to both a low intake of nitrogen compounds in water and a lower intensity of important gill parasites, such as the genera Trichodina, Cryptobia, and Chilodonella.
Another possibility is that genes within a group may have correlated levels of synonymous codon bias.
Analysis of such gene expression data has shown that functionally related genes may have correlated expression profiles [ 1].
In addition, the subjective complaints of the patients may have correlated poorly with objective radiologic evidence because of the complexity of the brain (Hsiao et al, 2010).
These two scenarios are not mutually exclusive; some resistance mechanisms may have correlated effects on both rate and yield (Fitzsimmons et al. 2010).
The survey did not ask about students' ability to speak a second language, which may have correlated with preparedness to care of LEP patients.
This assumption may be violated slightly with these data, given that individuals sharing a mother or father may have correlated survival chances or migratory behaviours (due to the effects of shared genes and potential trans-generational environmental effects).
Because blood is difficult to obtain from children and expensive to analyze, we hypothesized that family members who share the same indoor environment and have a similar diet may have correlated PBDE serum concentrations.
However, in other experiments, increased levels of Granzyme B activity have been observed in PBMC lysates (re-stimulated ex vivo with live influenza virus) in response to vaccination in older adults and which may have correlated with protection [ 27, 41].
