After 500 thousand times of standard axis load were applied, the rutting depth of the designed structure reduced by 43.4%.
2D- and continuous wave (CW) Doppler echocardiography with standard axis views were performed by one highly experienced cardiologist using a Sonos 7500 (Philips Medizin Systeme GmbH, Hamburg, Germany) ultrasound machine according to the recommendations of the American Society of Echocardiography [ 10, 18, 22].
The overall validation of this approach has been carried out by comparing the simulated and experimentally measured profile of the NAS 979 standard five axis contouring cone frustum profile.
Slopes and intercepts are estimated by standard major axis regressions for each genotype.
Microarray analyses used the limma package (version 3.14.4) (Smyth 2004); bivariate regression analysis used standard major axis regression with the smatr package (version 3.2.4).
We used standard major axis regression to test for the heterogeneity of slopes for the bivariate relationship of log-transformed body mass and VCO2, using SMATR, version 3.2.6 (Warton et al. 2006).
Metabolic rate scales positively with mass; to account for this relationship and for variation in both traits we used standard major axis regression to test for genetic effects on metabolic rate.
The PET data were reconstructed using an iterative ordered subsets expectation maximization (OSEM) algorithm (28 subsets, two iterations), a standard z axis filter, 3.74 mm post filter, a 128 × 128 matrix, and a DFOV 43.6 mm.
Ratios of peak areas of the lipid and the respective internal standard (y-axis) were plotted against concentration (x-axis), and calibration curves for each lipid were calculated by least square regression analysis with 1/concentration weighting.
We also acquired cine imaging using a true fast imaging with steady state precession sequence (echo time 1.3 ms, repetition time 2.6 ms, flip angle 60°, slice thickness 8 mm, gaps 2 mm, inplane resolution 4.17×2.73 mm) over multiple breath holds in contiguous short-axis slices encompassing the entire LV and three standard long-axis slices.
The ICCs in the free-living study ranged from 0.80 (Moves) to 1 (Fitbit Zip).> -wrap-foot> *P<0.05 **P<0.01 Bland-Altman plots indicate the differences between the tracker and the gold standard (y-axis) against the average of the two methods (x-axis).
