First, selection is acting on the same intermediate-frequency variants in each population. Under this scenario, convergence in allele frequencies is due to parallel evolution. Second, unwanted ...

Although a handful of cancer genes are mutated at high frequency, most cancer genes mutated in most patients occur at intermediate frequencies (2–20%). To provide therapeutic options for most ...

We’re talking about subminiature intermediate-frequency transformers, of course, and while we knew their purpose in general terms back then and never to fiddle with them, we never really ...

055TSMC_IFA_01 is an intermediate frequency amplifier (IFA) designed to amplify and transmit differential signals in the frequency range from 120kHz to 250kHz. The amplifier consists of two cascades, ...

We’re talking about subminiature intermediate-frequency transformers, of course, and while we knew their purpose in general terms back then and never to fiddle with them, we never really ...

The acronym “IF” as applied to superheterodyne receivers stands for “intermediate frequency” and so the above title is, to be a purist, an absurdity in referencing a “frequency frequency” but I've ...

The same went for plants exposed to high-frequency (158 to 160 kilohertz) and intermediate-frequency (34 to 35 kilohertz) sounds. But for plants exposed to playbacks of bee sounds (0.2 to 0.5 ...
