The cross-wavelet spectra and the wavelet coherence show strong correlation between the precipitation and discharge spectra in the low frequency intervals.
If the fraction of deleterious and advantageous mutations is negligible in the high-frequency interval and selection is negligible in the low-frequency interval, 1 − ξ can be thought of as the fraction of mutations prevented from fixation by weak or moderate negative selection.
We designed a real time and non-invasive monitoring system of very low frequency RR interval variability to detect the hypovolemic state resulting from internal and external hemorrhages.
To balance the contributions from high and low frequencies, the frequency interval was calculated on a logarithmic scale.
(These ranges can differ depending on the lab, species, and neural area. In [ 4], the low- γ frequency interval is specified to be 30 Hz–50 Hz, and the high- γ frequency interval is specified to be 80 Hz–150 Hz).
In antiquity, the relatively low human population density and the low frequency of peaceful intervals meant limits to the area of cultivated land, leaving wide regions open as grazing areas by migratory flocks.
Wavelet analysis offers long-time intervals for information with low frequency and shorter time intervals for information with higher frequency.
Using one-channel electrocardiogram (ECG), the detection system monitored in real time the very low frequency components of RR interval variability using Fast Fourier Transform FFTT).
A low frequency analysis in the interval 200 500 MHz with a lumped element model and a low frequency formula for the capacitance between the patch and ground plane indicates a dielectric constant in the order of 2.7 2.8.
In offline analysis, very low frequency variability in RR interval and systolic arterial pressure has been reported below 0.1 Hz during head-up tilt (HUT) tests in conditions similar to hypovolemic states in humans.
Where parentage was unclear for gametes with low frequencies, the possible frequency interval is indicated; for common gametes, doubtful cases were simply excluded.
