We modeled on a 2-week time scale because of the 2-week sampling of MESA Air supplementary monitoring instruments; this allows for flexible aggregation of predictions to time scales of interest for health effects analyses (e.g., 12 months before clinic visit).
Given the daily treatment regimen for statins, temporal fluctuations due to statin PK can be neglected for predictions on the days-weeks time-scale.
But within any given week, the time scale that matters to traders, the movement of the market seems random.
Additionally, the administration of an anti-VEGF agent may affect receptor expression over days and weeks, the time scale investigated in the present study.
Results from a study of samples taken at Cinder Pool showed that the concentrations of thiosulfate and polythionates changed over a time scale of weeks to months.
Currently, Yahoo's acquisitions are being integrated into its product teams very quickly, on an average time scale of weeks rather than months.
Experimental results suggest that, at the Coles Hill site, the oxidation of U IV) to U VI) and subsequent precipitation of uranyl phosphate occurs rapidly (time scale of weeks) relative to ground water transport (e.g. 20 m/a).
This mechanism has been previously used to fit a dynamical model to data on the 1918 influenza pandemic and the best fit estimated that the replenish of the susceptible pool due to waning immunity could occur in a time scale from weeks to months [47].
A proposed model [86] to address these characteristic features of influenza infection and evolution was that the host immune system responds in a manner that inhibits immediate re-infection but is short-lived with a time scale of weeks to months and is nonspecific to intra- and inter-subtypes.
Therapeutic adjustments–such as increasing the dose of erythropoiesis stimulating agents or the administration of iron are made on a time scale of weeks to months.
ADP was used in place of the common ATP mimic, ATPγN, because of the very slow hydrolysis on the time scale of weeks that was observed with ATPγN.
