The phrase "a minimal spot" is correct and usable in written English.
It can be used to describe a small or insignificant location or area, often in a context where size or importance is being emphasized.
Example: "After searching for hours, we finally found a minimal spot to set up our tent for the night."
Alternatives: "a tiny area" or "a small location".
Our main experimental intention is to focus light to a minimal spot size in all spatial directions simultaneously.
However, to limit signal overspill between neighbouring spots, we designed a medium-density layout with a minimal spot distance of 2 mm.
Quality criteria included a minimal spot size, a median mean ratio of at least 0.9 for each spot, nonsaturated intensity, a signal well above background, and a minimal signal intensity.
OME-TIFF image stacks were transferred to IMARIS (Bitplane) and subjected to spot detection in the CREST/CENP-A channel with a minimal spot size of 0.58 μm to detect kinetochores.
Quality criteria included a minimal spot size, a median/mean ratio of at least 0.9 for each spot, non-saturated intensity for both channels, a signal well above background and a minimal signal intensity for at least one channel.
To date, even for favorable beam source conditions a minimal focus spot size of slightly below 1 μm was reached.
Using the proposed minimal spot distance of 2 mm, a 10 cm × 7 cm nylon membrane can accommodate 384 genes printed in duplicate, and multiple membranes can be used in the same hybridisation reaction.
To this end, spot quantification range and minimal spot distance were calculated and implemented.
Specially positioned internal and external control (EC) series on ToxArray™ were developed and characterized in order to eliminate the effects of these biological variables as well as reduce additional technical sources of variability, including uneven hybridization artifacts, minimal spot replication and print tip carryover.
You may experience minimal spotting, but this should not last more than a day.
This used the standard adaptive circle segmentation method and converted the information from images into a value between 20 to 2. The flagging convention was to define a good spot as having a minimal of 65% of its pixels larger than background plus two standard deviations.
