Through careful calibration and diligent work, the researchers running it were able to eliminate most of the residual background sources of radiation that could mimic dark matter.
Two background sources of exome data were used because the 1000 Genomes Project exomes can over-predict the performance that will be obtained for real patient exomes.
Thus, the genetic covariances are background sources of phenotypic covariances among traits that confound not only the inference of causal effects between pairs of traits, but also the search for causal structures, because algorithms may interpret such covariances as due to causal relations among phenotypes.
After allowing for the statistically significant random effects of background sources of variation, there remained strong evidence of variation between individuals in the effects of alendronate on hip bone mineral density (P=0.008), shown in fig 2 by the difference in the variance trajectories for alendronate and placebo at year 1.
Consequently, measurement of increased soil exposure is limited by the magnitude of this exposure relative to background sources of inorganic arsenic.
Because the concentration of total arsenic in the tap water of the recruitment area was much lower than that recommended by the World Health Organization (WHO) (10 μg/L), the participants were considered to be derived from the general Chinese adult male population with background sources of arsenic exposure.
The correlation between personal and ambient NO2 (r = 0.43) as well as the confounding of the ambient NO2 association by personal NO2 are consistent with the view that in addition to local traffic sources, some part of the association we found between personal NO2 and FEV1 was attributable to ambient background sources of NO2.
We considered blood lead concentrations ≤10 µg/dL as consistent with exposure to environmental background sources of lead, and concentrations >10 µg/dL indicating elevated exposure to a point source of lead, as would occur with ingestion of lead fragments.
This is consistent with human free BPA data collected in a biomonitoring study of pregnant women exposed to background sources of BPA (Schönfelder et al. 2002).
In the RTI, the most important background sources for the evaluations of scientific promise have been the Science Map studies of the Japanese NISTEP, the National Institute of Science and Technological Policy [7].
