The input temporal frequency F is confined within the range of 1 to 50 Hz, consistent with feasible biological frequencies [1], [17].
The amplitude of each sine and cosine wave determines its contribution to the biological signal; frequency domain analysis displays the contributions of each sine wave as a function of its frequency.
Graphical analysis was performed using Prism (GraphPad Software, Inc .. To interpret the HRV data and the biological significance, frequency domain was analyzed with the power spectral densities (PSD) of the R-R interval time series based on the fast Fourier transform.
For functional annotations, each proteome was analyzed with BLAST2GO (Conesa et al. 2005) and gene ontology (GO) terms (belonging to Biological Process) frequency distributions were used to implement the nonparametric Kruskal Wallis test of variance (P < 0.01) in order to identify enriched gene functions among oral versus nonoral, genital versus nongenital, and established versus putative.
We suggest that in these biological systems frequencies beyond the bandwidth are not necessarily noise; they may contain useful temporal information that the system is simply incapable of processing.
It is noteworthy that this neither implies that we detect all biological variants at frequencies above 0.3% nor does the frequency of a SNP among the reads necessarily reflect the frequency of that SNP in the sample.
Those patients underwent standard care, which included periodic visits, and biological assays with frequency based on the level of glomerular filtration rate (GFR).
Table 1 presents the sociodemographic, behavioral and biological characteristics, including frequency of STI and other genital tract infections, in those FSW with and without cervicitis.
The 3782 T>C 3' UTR variant of BRIP1/ BACH1 is predicted to alter the folding of the transcript; however, the biological significance and frequency of this change in the normal population has yet to be determined.
