The search direction (d_{k}) is defined by d_{k} = - g_{k} + beta_{k}d_{k - 1}, quad k = 2, 3,ldots, (3) where (g_{k} = nabla f(x_{k})), (beta_{k}) is a scalar, and the steepest descent method is used as an initial search direction, i.e., d_{1} = - g_{1},quad k = 1.
Blast2GO use an initial BLAST search, the gene ontology terms (GO terms) extracted from hits in the initial homology search and an annotation rule to assign GO terms to the individual query sequences in a dataset [ 26].
All sixteen pacifastin-related precursor peptide sequences from the Uniprot protein database were used as queries for an initial search of genomic/EST databases.
(129) ( omega^ ) is the value of ( omega ) for which one of the set partition indices ( sigma^ ), obtained from an initial search using ( sigma_{i} = { i = 1,2,3, ldots,q} ) produces the best GFMAPR performance, measured using some performance evaluation approach.
Each module uses an initial exhaustive BLAST search as its starting point.
By performing an initial search using fewer sampling points that satisfy the Nyquist sampling theory, the proposed algorithm can derive a satellite list, which is sorted by their signal strengths, in a timely manner.
The structure was solved by molecular replacement with Phaser McCoyy et al., 2007) using PLK1-PB1 (3P34, residues 147 331) as an initial search model.
After an initial search using MESH keywords for risk factors (i.e. education, smoking, physical activity, caffeine/coffee/tea, alcohol, antioxidant/vitamin E, homocysteine and fatty acid) and a title containing the words (cognitive, dementia and Alzheimer), we assessed the retrieved papers for relevance by reading the titles and abstracts.
With an initial search that uses only a fraction of the original IF data and subsequent search space pruning, the proposed method can reduce the computational cost of satellite acquisition process without sacrificing the number of captured satellites.
An initial search using the keywords described located 2953 studies.
