Such observables are the consequence of the total set of molecular components g i j of m i. Describing O 2 m i as f(g i j ) having just a context-free listing of g j i provides no better system representation, as we end up with the mapping O 2 m i := g i j.
We further see G as the total set of molecular components of M. With G we break up the boundaries to individual m i, and obtain a mapping of O 3 M := G, which allows describing the community observable as a function of the community genome [ 50].
We identified the biological processes (Gene ontology categories [ 15]) and pathways representing the molecular interactions and reaction networks (KEGG [ 16]), which are enriched within the total set of 810 miRNA-targeted components of the protein complexes (Additional file 3, Table S3 and Additional file 4, Table S4 online).
The basic goal of PCA is to reduce the dimension of the data, which is accomplished by choosing p components instead of the total set of m variables (gene expression), where p≪m.
Total number of subsystems; The set of components in the i-th subsystem; Number of type j component in subsystem i; Total number of component in subsystem i; Failure rate of component j in subsystem i; Repair rate of component j in subsystem i; Cost of component j in subsystem i; Weight of component j in subsystem i; Total weight of system; Availability of system; Cost of system.
These alternative scenarios include a component contributing < 1% to total PM2.5 mass, but with concentrations below detection limits that co-vary with PM2.5 total mass, or a component or set of components that co-vary with the identified key components.
To investigate if the immunocytochemical results were reflected by the change in total protein levels when incubated with the same set of components, we performed Western Blot analysis.
Because of these limitations, health risks could be associated with the true concentrations of a component or set of components that co-varies with PM2.5 total mass, even if measured concentrations in this data set do not co-vary with PM2.5 total mass because of measurement error.
Further, we did not investigate the possibility that observed PM2.5 health effects could result from a set of components with a collective concentration that co-varies with PM2.5 total mass, although individual component concentrations do not.
Biology has assembled a specific set of components.
