Researchers do not like the extra work of formulating and registering predictions in advance; they continue to resist publishing their unpredicted ("negative") results.
For unpredicted negative MOL-PCR results (SAL-20, SAL-38, SAL-47, SAL-58 and SAL-71), mismatches were observed in the alignment of the PCR amplicon sequence and the target-specific sequence of the upstream and downstream probes, which prevented adequate annealing of the probes and explained why no ligation occurred.
Finally, ion drift meter data from Defense Meteorological Satellite Program spacecraft suggest that unpredicted positive and negative spikes found in high latitude accelerometer data reflect encounters with strong head and tail thermospheric winds driven by anti-sunward convecting plasma.
However, they have also identified a number of issues for further investigation such as that EDA appears only to be a reliable measure in infants at higher levels of general arousal, and that pupil size appears to show consistent, yet unpredicted, patterns of negative phasic change relative to other indices.
To assess the number of correctly predicted promoters (true positives, TPs), false predictions (false positives, FPs) and unpredicted promoters (false negatives, FNs), we define the maximum distance that a prediction is allowed to be from the true site.
When primers pairs were targeted within the altered sequence, negative or unpredicted bands could occur and led to a low frequency of detectable PCR products in validation experiments.
There was a scene happening, unexpected, unpredictable and unpredicted, but there and real.
The crisis was not an act of God, unpredictable to and unpredicted by ordinary mortals.
Rapid and unpredicted rate of urbanization have negatively impacted the lowland tropical forests.
In other words, the occurrence of an unpredicted or surprising event may play the role of negative reward, irrespective of whether the surprising event entailed the presence of absence of a stimulus.
With this method, unpredicted proteins, either due to unusual base composition or to fragmentation at the contig level, would lead to a negative result.
