Less effective were the two works that followed, "Autumn Music 2" and "On the Nature of Daylight," both of which veered perilously close to background music.
However, the authors concluded that the spine uptake was too close to background values.
In this study, the methylation profiles of TVB promoter in six RCSs were much close to background line 63 than to line 72.
However, the increase in source level at long distance (121 dB SPL, Tab. 1), indicated that M. molossus reduced the output close to background.
For two of the bodywall muscle gene lists, the ChIP-seq data was significantly enriched whereas the ChIP-chip data was close to background.
We applied several filtering steps to discard genes and exons with expression values close to background in an effort to minimize the false positive rate (see Methods).
Probes with signals close to background (average signal<500) as well as probes which were flagged as saturated by the Agilent Feature Extraction Software were excluded.
Additionally, severe hypoxia, secondary energy failure, impaired mitochondrial function and lack of ATP could eventually interrupt the apoptotic cascades to the extent that the level of caspase-3 activity is brought down to a level close to background [52].
To eliminate signals that were close to background levels, probes which showed intensities lower than the median raw intensity of 111 negative control probes on each slide were excluded from analysis.
In vegetative cells growing in the absence of uracil, urg1 shows close to background signals on microarrays and is among the 10% most lowly expressed genes [19], and it is marginally periodically expressed during the cell cycle [20].
Data were then normalised by dividing each reporter signal with the median signal intensity of the whole microarray, and then filtered to remove noisily or arbitrarily regulated genes with expression levels close to background.
