To investigate within-couple correlation of urinary BPA concentrations, we first noted that the covariance parameters in the mixed-effects models were estimated to be approximately 0.04 for subject, 0.04 for within-couple collection date, and 0.11 for residual variance.
Table 1 presents a demographic summary of study participants, overall and stratified by gender, controlling for the within-couple correlation.
The variance component for couple was estimated to be zero and was dropped from the models, but the random effects for subject and within-couple collection date were retained.
To account for possible correlation of measurements, random effects were included initially for subject, couple, and within-couple specimen collection date.
Even though there are more than thousand process states and more than hundred candidate sensor locations, the optimal sensor network design problem for maximizing process efficiency could be solved within couple of hours for a given budget.
Serum was centrifuged (1500 g for 15 min at 4°C) and stored at 4°C until measurement within couple days for biochemical markers, such as triglyceride, LDL cholesterol, HDL cholesterol, insulin, plasma glucose, glycated haemoglobin (HbA1c), uric acid, CRP, and BNP were measured enzymatically in the clinical laboratory of Kitasato University Hospital.
The reward for my curiosity proves transient, for, within a couple of minutes, the gleam on cream goes as sunbeams striking the fungi are lost behind a cloud.
A total numerical model was first established for simulation, where the electrical system, the mechanical system, and the acoustical coupling in the panel speaker are accounted for within a coupled framework.
However, as discussed in Section 2, discrete models usually provide a more comprehensive setting that accounts for the complete set of fiscal and social incentives, for explicit intensive versus extensive margins of response, and for joint decisions within couples.
Paired-samples t tests were used for comparing mothers and fathers within couples for the BSS global and thematic scores.
Descriptive data were presented for each individual, differences within couples and the mean values for each domain with ranges.
