Specifically, if expression of A and B are measured simultaneously in single cells as a function of time, we can determine how their means (a and b), downstream propagated noise (ηbbprp2) and shared noise (ηab2) evolve over time.
"People change over time.
We find that the downstream progress increases over time when the upstream evolution is fast or linear, but it is indefinite when the upstream evolution is slow.
The lme growth analyses revealed that there has been a significant linear decrease (t4188 = −11.03, P < 0.0001) in length of downstream migrating smolt over time (Supplementary Fig. S1), with smolt size decreasing by an average (±SE) of 0.52 ± 0.05 mm year−1.
Proving the value for primary care requires gathering data from the primary care provider and all the downstream providers, analyzing it over time to show the benefit of good preventive care avoiding need for treatment later, and structuring the controls and comparisons in a way that insurance actuaries, for example, will buy.
The model therefore predicts that careful project management will be necessary to match discovery output over time with downstream development resource capacity. Figure 18 Time chart showing simulated preclinical candidate output as a function of year for a working group comprised of the following: (A) 10 chemists and 10 biologists with an average output of 0.6.
Instead the model's dynamic nature where transmission, host infectiousness and host immunity are intimately linked, changing over time, allows downstream intervention impacts to evolve during the simulation.
While our study did not link the changes in IFNγ promoter methylation in buccal cells over time with downstream biological events as the Liu et al. and Gonsky et al. studies did, it does for the first time show that the time course for changes in DNA methylation can be as short as several days in a pediatric cohort.
This also indicates that, although Shh expression is observed at the posterior end from earlier stages (specifically, from stage 17), its expression level and/or downstream signaling activity dynamically changes over time, causing a temporal dependence of the effects of SHH signaling on the tissue growth rate.
Given the rapid decline in herbicide concentrations over time and the downstream dilution effect on herbicide concentrations, under operational conditions, and when applied according to manufacturer's instructions, the downstream risk of these two herbicides to human health and aquatic organisms appeared to be low and was within regional rule requirements.
