The signal perturbations due to A and B class flares are masked by background noise (signal variation), so we considered only C, M and X flares.
Auditory cues produced by the stepper motor were masked by background noise from a buzzer.
Maddox et al. have now explored this phenomenon in experiments that involved human subjects listening to an audio stream that was masked by background sound.
Although it is possible that renovation-related exposures increased during this time period, but were masked by background declines in EBL, such an effect was not reflected in the overall proportion of children with EBL.
Therefore, this MS device significantly reduces the noise level observed in the traditional SRM/MRM mode and can quantify target peptides with small peaks that are masked by background noise in QqQ.
However, it has to be considered that EcoTILLING is prone to false negative detection because some fragment sizes are masked by background "noise", due to miss-priming, or because of weaker fluorescence toward the top of each lane and increasing fluorescence "noise" toward the bottom [ 3, 37, 38].
Treating U-2 OS osteosarcoma cells with the serine/threonine phosphatase inhibitor calyculin A resulted in increasing levels of phosphorylation at this site that were masked by background bands in direct Western blots, but were clearly visible after immunoprecipitation with an anti-RelA antibody.
No mass loss of BDE-209 was observed in the system adsorption test; however, this could be masked by the background contamination with BDE-209.
This weak rescue suggests the presence of multiple minor-effect HI loci, but we were unable to map these loci to high resolution, presumably because weak rescue can be masked by genetic background effects.
Therefore, the results may be masked by a high background of irrelevant transcripts expressed by stem tissues surrounding the primordia.
