Initial introgression does not have to occur at a high frequency to result in a mismatch between species identity and mitochondrial DNA type spanning an extensive area.
However, if BTS were repeatedly introduced in large numbers over multiple years (as we have been told was the case by people familiar with the initial introductions in the 1950s), then pure non-native salamanders would have been present in sufficient frequency to result in the production of high-fitness bcBTS families during the second-generation of admixture.
We show that ignoring the sources of variation in allele frequencies tends to result in overestimates of power and, consequently, in studies that are underpowered.
The average stimulation frequency used in this study was 120 Hz, more than double the frequency found to result in pain relief and pain freedom in previous acute studies (25).
Based on analysis of the chordwise and spanwise pressure correlation length scale, the reduction in lift spectral level at low reduced frequency appears to result from distortion of the inflow by the mean velocity field.
Limiting the frequency information to result and discussion(R&D) sections(FreqRD) only did not help the performance.
Additionally, we found that the duration of a light pulse beyond a certain point, independent of frequency, fails to result in higher spike rates in neurons expressing ChR2, but rather silences them.
Importantly, the spontaneous activity we report is of a frequency known to result in neurogenic inflammation following electrical stimulation of peripheral nerves, through release of SP and CGRP (White & Helme, 1985).
These aspects, together with the resulting coupling of mode frequency to amplitude, result in a musical instrument that is unique.
Low-frequency stimuli also tended to result in stronger activation than high-frequency stimuli (although the ¼-kHz stimuli evoked slightly less activity than the ½- and 1-kHz stimuli).
