Signal averaging was accomplished by collecting multiples of such spectra rather than by multiple acquisitions at each frequency.
This indicates that insertions/deletions in these specific regions are acquired by unknown mechanisms, probably by multiple acquisition events and the spread of an ancestral acquisition through the species by recombination from other bacterial strains.
The observed discrepancy between the nucleocytoplasmic and the plastid genealogy might be better explained by postulating multiple acquisitions of plastids in these eukaryotic lineages.
Within-scanner measurements are remarkably reliable across scan sessions, being minimally affected by averaging of multiple acquisitions, B1 correction, acquisition sequence (MPRAGE vs. multi-echo-FLASH), major scanner upgrades (Sonata Avanto, Trio TrioTIM), and segmentation atlas (MPRAGE or multi-echo-FLASH).
Gallo became the world's largest wine company, and only in 2003 did multiple acquisitions by rival Constellation Brands of New York state push that company slightly ahead.
However, to obtain quantitative PCI information it is necessary to perform multiple acquisitions by changing the optical configuration, i.e. acting on the optical setup with mechanical movements [ 9].
Although the use of different satellite systems provides multiple acquisitions every month, data availability is constrained by cloud cover and other limitations.
It appears that ST9 has achieved methicillin resistance through multiple acquisitions of SCC mec, as indicated by the recovery of distinct PFGE and SCC mec types.
Hence, the multiple acquisitions of heteroecy revealed by our study have probably promoted the diversification of some Brachycaudus species.
However, the observations on NIRVs, along with the recent demonstration of multiple acquisitions of bacterial genes by fungi [ 23] shows that, although HGT is probably much less pervasive in eukaryotes than it is in prokaryotes, sequencing of multiple, diverse eukaryotic genomes reveals substantial lateral gene traffic.
