Time is merely a measure of cycles of change within the world.
The geometric mean of the SG-adjusted BPA concentrations from two spot urine samples collected during each IVF cycle was used as a measure of cycle-specific urinary BPA concentration.
From the envelope of the call (amplitude vs. time), we measured mean, minimum and maximum F0 (F0minn, F0min and F0max), the number of pulses (Pulses), the duration of the groan (Duration) and a measure of cycle-to-cycle frequency variation (F0 perturbation), known as Jitter [ 19].
Solar oscillations provide the most accurate measures of cycle dependent changes in the sun, and the Solar and Heliospheric Observatory/Michelson Doppler Imager (MDI) data are the most precise of all.
Jitter is a measure of the cycle-to-cycle variation of the pitch period.
To investigate the effects of PTHRP-R overexpression on mitogenesis, we first examined the effect of exogenously added PTHRP on thymidine uptake, as a measure of cell cycle progression.
We have observed that compared with Ki67 staining, which is retained in non-proliferating cells for a considerable time period, BrdU incorporation is a more sensitive measure of cell cycle arrest following chemotherapy treatment.
In some conditions the authors chose direct incorporation of nucleotides as a clear measure of cell-cycle reentry, while in others they use PCNA immunostaining.
The model parameters for a given individual, were obtained by using measured data of cycle-ergometer tests from two different cycling scenarios.
To measure the duration of cycle phases, the recorded film was analysed frame by frame.
We use MSA unemployment, averaged of over 3 months (to reduce measurement error), as our principal measure of the business cycle.13 In work not shown, the use of a lagged unemployment measure produced results similar to those shown.
