In this section, an approximate solution will be searched by using the method of multiple scales.
Public domain databases including PubMed and the Cochrane database were searched by using predefined keywords.
Negative strand HCV-RNA, a marker of HCV replication, was searched by using tag-RT-nested PCR (tag-RT-NPCR).
To improve the spatial uniformity, the optimal surfaces are searched by using simplex algorithm for an extended LED system.
Afterwards, the remaining routes are searched by using ACO in the route exploration stage, which is executed concurrently with data transmission.
First, public-domain databases including PubMed and the Cochrane database were searched by using exploded Medical Subject Headings and the appropriate corresponding keywords: "NEUTROPENIC ENTEROCOLITIS" OR "TYPHLITIS".
Cohort studies were searched by using the terms "risk", "prognosis", "cohort analysis" and "follow up study" and we then used the Boolean term "or" to combine combined this with a published search filter for identifying clinical trials [13].
The resultant annotation was searched by using specific keywords (e.g. phage, integrase, tail, capsid, terminase, portal, head, neck, fiber), and for the positive matches a neighbor analysis was performed in order to find more phage-like genes.
For identification of transcriptional factor binding site motifs, each promoter was searched by using TRANSFAC (version 7, 2005) (http://www.gene-regulation.com/pub/databases.html) with a cut-off value >0.9.
Outliers can also be searched by using a Galbraith plot [ 40].
