The numeral simulation and experiment results show that, the proposed integral methods have high precision, strong noise resistance and are very stable in repeated measurements.
The 1σ precision of the stable isotopic measurements in this study based on multiple analyses of an in-house carbonate standard (n = 28) is 0.03‰ for δ13C and 0.06‰ for δ18O, consistent with the long-term precision for this instrumental setup (0.06‰ for δ13C and 0.08‰ for δ18O).
These results increase the applicability of available physiological models for paleoseasonality reconstructions from stable isotope measurements in fossil or archaeological enamel, the composition of which is determined in equilibrium with blood values.
Money should be stable in value, just as measurements of distance or time are stable.
Previous studies have shown that PFASs are stable in human serum, and measurements obtained from serum or plasma samples gave comparable results (Ehresman et al. 2007).
Other sample types and measurements from this core, e.g. stable isotope measurements, are described in detail in [33, 36].
Without some form of intervention, Hbmass is considered to be constant, especially over a period of a few days, so that differences in measurements taken under stable conditions can be attributed almost exclusively to measurement, or analytical, error.
Relationships between Mayo scores and both PRO measurements were stable, in the right direction (reflecting benefit to the patient), and approximately linear.
These values deviate from the nanovesicle diameter determined by AFM for dispersed ac-A6D-COOH and DA6-COOH nanovesicles but resemble the size of the nanovesicle clusters suggesting that these clusters are stable in PBS in which DLS measurements were performed (Table 1, Figure 3).
Monitoring efforts should also include stable isotope measurements, such as change in C and N ratios, in lower- and upper-trophic-level taxa in order to detect shifts in trophic structure and position (Hobson 1993; Hobson et al. 1994).
