His emigration gave Ted reason to write dozens of long letters over a period of half a century (though their frequency tailed off in later years, as he lamented in one of his very last poems, Brother Peartree).
Above 400 °C, the semicircle for grain interior conductivity diminished and the lower frequency tail appeared as a semicircle (Fig. 5b).
Overall, this suggests that although PCR and Illumina machine error do contribute substantially to the mutation spectrum, removing them does not substantially affect the high frequency tail end of the spectrum or the minimum frequency thresholds.
A possible explanation is based on the sharp slope of high-frequency cutoffs and shallow slope of the low-frequency tails of auditory fiber frequency responses.
To avoid biasing the results, in the fits n was fixed (n = 4, after seeing that it effectively retained the trend in the high-frequency tails of the power spectra).
Spectra of the turbulent wind fluctuations are found to follow the − 53 -power law at the high-frequency tail.
The low-frequency tail is probably due to electrode-sample interface effects (e.g., ten Grotenhuis et al. 2005).
"Anomalous Microwave Emission" (AME) refers to dust-correlated emission in the 15-50 GHz frequency range that is far stronger than had been expected from the low-frequency "tail" of the thermal infrared emission from dust grains at ~20K.
As the correlation length decreases, the Raman peak is expected to shift toward lower frequencies and the line shape will become asymmetric with a low-frequency tail.
The resistivity of the brine-bearing quartzite was determined by fitting the semicircular part of the impedance data, excluding the low-frequency tail.
The low-frequency tail is possibly approximated by Randles circuit (Randles 1947), which includes a double-layer capacitor (Cdl), charge transfer reaction resistance (Rct), and Warburg impedance (Zw).
