In the case of dark field imaging, the beam of a bright white light-emitting diode (LED) was used so that the field of view remains dark if no scattering entities were present in the sample.
'Composition-based' approaches are an alternate strategy that exploits nucleotide usage information extracted from the reads to detect which taxonomic entities are present in the sample.
The BANNER NER system marked 365 204 gene/protein entities in 54 051 citations in the sample, averaging two mentions per citation overall and almost seven per citation for those containing at least one tagged entity.
Therefore, the interactions, and the set of distinct entities in a sample, can be difficult to interpret from 16S studies alone.
The GMYC delimitation method combines phylogenetic and phylogeographical approaches to estimate the number of well-separated entities in a sample.
Use of a foreign key pointing to the 'parent sample' in the Sample entity allows to track each final product or aliquot to the master sample.
Most important entities are the pH value during hydrolysis, the presence of nutrients and co-factors in the sample, and the modification of the substrate.
After adding a third entity (3 equiv of dye), there are now approximately 2500 unique ligand-to-scaffold ratios present in the sample.
In (Deus et al., 2010), we envisioned a hosted service depicting complex relationships between samples, patients and other higher order entities in the TCGA.
Second, while phylogenetic trees usually aim at inferring the relationships between homologous sequences and their hypothetical ancestors, sequence similarity networks instead display significant resemblances between any sequences (in gene and protein networks) or any entities (in genome or sample networks), in a topologically less constrained, and in practice much more inclusive, framework.
