The phrase "a decrease in background" is correct and usable in written English.
It can be used in contexts discussing changes in environmental conditions, data analysis, or visual settings where background elements are being reduced.
Example: "The study showed a decrease in background noise, which improved the overall quality of the recordings."
Alternatives: "a reduction in background" or "a decline in background".
The mutual interplay between excitatory feedback and mutual inhibition leads to increased responsiveness to target object detection and a decrease in background response [23].
The analysis indicated a decrease in background fixation durations for the New/Old condition (F 1, 30) = 3.98, p = .06, η2 = .12) with no linear trends in the other conditions.
One of the most marked transcript expression changes observed was a decrease in background potassium channels.
Tumour identification was clearer on the later images due to a decrease in background activity over this time.
Recovery of gain following a decrease in background took more time, as indicated by the slower kinetics at light offset.
However, without a decrease in background levels of proliferation, a small localized increase in proliferation might be difficult to detect, particularly if the additional cell cycles were asynchronous.
The stretching method in the PII interprets the time delay of an ACF as being caused by a decrease in the background velocity structure; when the background seismic velocity decreases by α %, the time delay is given by dt = α/100 for a lag time of t (e.g., Sens-Schönfelder and Wegler 2006).
There is a decrease in water background reflection from 550-750 nm; so to get some information on background the difference of bands 3 and 2 can be applied.
Using appropriate and specific virus purification procedures (such as sucrose density gradient centrifugation), we have found that non-specifically labeled cellular debris and excess dye can be efficiently removed, which leads to a substantial decrease in background fluorescence.
The bottom of the GPi was recognized by a sudden decrease in background noise and multi-unit activity as the optic tract was approached (Fig. 2).
However, 10 and 100 μg/mL maghemite and 100 μg/mL magnetite caused a significant decrease in background APF fluorescence signal, which could be due to adsorption onto the surface of the NPs, thus quenching the fluorescence response.
