It can be used when describing a rapid decline or reduction in a particular quantity or condition.
Example: "The study showed a fast decrease in the population of the endangered species over the last decade."
Alternatives: "a rapid decline in" or "a swift reduction in".
Conclusions: Studying the kinetics of plasma progesterone after surgical treatment of ectopic pregnancies revealed a fast decrease in progesterone.
BMDTB was normal at diagnosis, with a fast decrease in the first 32 weeks, in which chemotherapy was relatively intensive.
Indeed, in vitro video time-lapse imaging experiments demonstrates that CR cells incubated with Sema3E-AP showed a fast decrease in branches of the leading neurites compared with SEAP-treated cells, which correlates with lower cell migration and soma movement (Supplementary Fig. 13, Supplementary movie 7).
However, also when TADH is incubated with 2-cyclohexenone, a fast decrease in the absorbance is detectable (entry 8).
From the figure it is clear that there is a fast decrease in the concentration of the eosin in presence of the AuNPs.
Tumours subjected to TMZ and 177Lu-TATE initially showed a fast decrease in ktrans, reaching minimum values at day 4 ((2.2 ± 2) × 10−3 min−1 for 177Lu-TATE) or day 5 ((2.0 ± 2) × 10−3 min−1 for TMZ).
This faster decrease in central CRH release would lead to a faster decrease in the ACTH release in the LR than HR subjects and as result to a faster return to the pre-stress or even below the pre-stress levels.
Higher chloride concentrations led to a faster decrease in total organic carbon (TOC), chemical oxygen demand (COD), and absorbance values at 228 nm.
At transmembrane pressures slightly higher than the capillary pressure, a faster decrease in the interfacial tension resulted in the spontaneous formation of smaller droplets with a narrower droplet size distribution.
Neutrophils of cows in SCHI had a faster decrease in cytosolic iCa2+ after stimulation with ionomycin (9.9 ± 1.0 vs. 13.6 ± 1.4 Fluo-4 Fura Fluo-4 Furad Redio) in vitro.
The pH decreased slightly over time with a faster decrease in samples containing sludge.
