The Earth's motion will cause the frequency of a signal from the sky to drift in frequency, for example.
ω m is the magnetron frequency representing a drift in the radial plane around the centre of the trap.
Different types of emissions have been observed: emissions called Power Line Harmonic Radiation (PLHR) with frequency lines exactly separated by 50/100 or 60/120 Hz, emissions with frequency lines not exactly separated by 50/100 or 60/120 Hz and drifting in frequency (MLR).
Although many machines operate at a nominal single frequency, very often there is drift in this frequency.
Intuitively, an increase in resonance frequency for more depolarized regimes should lead to drift in oscillation frequency of the network due to drift in resonance frequency.
In isolated populations, where a relatively small number of individuals found a new population, rare variants that were present in the founders can drift up in frequency as the population expands, thus increasing power for genetic association studies.
Figure 13 Due to a slow drift in the mains frequency or a variable exposure time, the amount of gathered light varies in time.
If a second mutation occurs at the corresponding site (GU → GC), drift in gene frequency may lead to a domination of this new base pairing in the population (RNA6A-D, RNA7A-B, D and RNA16A).
If the long exposure time is not a multiple of the fluorescence period, the amount of integrated light can vary per field due to a slow drift in the mains frequency.
The drift in oscillation frequency was the largest in IF IF networks, being increased especially when II was scaled up (Fig. 10 C), a scaling that was accompanied by progressively more frequent desynchronization events.
While no such admixture was detected, it remains possible that ancient admixture occurred at a low level (e.g. 1%), the introduced Y chromosomes then drifted up in frequency to their present level, and the introduced autosomal segments remained at, or drifted down to, undetectable levels.
