For this reason, most IMS studies, including those of the author's group, have reported the analyses of abundant metabolite species, particularly membrane-constituting lipids.
Subsistence remains are not abundant, but microwear and technological analyses of flaked stone tools can be used to infer production of dugout canoes and document trends that reflect new sustainable and resilient lifeways and complex social networks.
In a few of the RT PCR analyses of less abundant transcripts, no bands were detectable after the first round of PCR and nested primers were designed.
Here again, analyses of newly abundant sequence data in the late 20th Century showed that rather than a highly congruent coalescence of genes at the times of speciation events, the coalescence times of alleles among species are highly variable.
Alignment extension and phylogenetic placement has interesting applications in the analyses of increasingly abundant sequencing data produced by NGS technologies and we have implemented extensive support for such data.
Chemical analyses of the most abundant components in rocks usually are presented as oxides of the elements; igneous rocks typically consist of approximately 12 major oxides totaling over 99 percent of the rock.
(C ) CID and OzID MS analyses of the most abundant sex-specific TAGs reveal significant combinatorial complexity.
In addition, both phylogenetic and age distribution analyses of the most abundant LTR retrotransposon superfamily (Gypsy/Ty3) suggest that high TE levels in salamanders reflect persistence and diversification of ancestral TE families within salamander lineages rather than horizontal transfer from distant branches of the Tree of Life.
Mass spectrometry (MS) analysis was performed using a continuous duty cycle of survey MS scan followed by up to ten MS/MS analyses of the most abundant peptides, choosing the most intense multiply charged ions with dynamic exclusion for 120 s.
Trinucleotide repeats (54 78%) have been more abundant than dinucleotide repeats (17 40%) in analyses of EST databases of several grass species [ 22, 27, 43, 45].
