Moreover, Outex database offers several variations of acquisition conditions (illumination, spatial resolution, and camera rotation), where all images are of size 128×128 pixels.
Cheng and Currie [ 10] suggested that this variation in clinical presentation may be caused by one or more of three factors: variation in mode of acquisition, variation in host immune response, or variation among bacterial strains, including presence/absence of virulence factors.
In conclusion, our tests have demonstrated that the proposed extractor outperforms the other techniques with respect to noise, holes and variation of the acquisition viewpoint.
Biological replicates were analyzed two or three times to determine the technical variation of MS acquisition, as discussed further below.
The secondary objective was to evaluate the potential yearly variation of the acquisition of these respiratory pathogens by comparing results from the 2012 and 2013 Hajj seasons.
Since every sample is an aliquot of the same batch of plasma (see section 2.2), the variation observed across different acquisitions, accurately reflects the intra-plate variation (variation within the same day of acquisition), inter-day variation (variation on different days of acquisition), and inter-site variation (variation between different sites).
This value is not only normalized for the specific cell size and chromatin distribution but also robust to variations of image acquisition and threshold settings.
This allowed retrospective variation of the effective acquisition time for generation of image data with different noise levels.
Here, we show that antibody-driven antigenic variation in one domain of the H1 hemagglutinin Sa site leads to compensatory mutations in NA, resulting in NA antigenic variation and acquisition of drug resistance.
However, only a few studies have investigated the impact of variation in acquisition time after I-MIBG administration on the late H/M ratio [ 9, 10].
