Each loudspeaker has a frequency at which it resonates most readily.
"It seemed to hit a frequency at the right time," said Helen Jensen, whose steampunk name is La Falconesse.
A natural frequency is a frequency at which the system will vibrate if initially disturbed from rest and not subjected to any external loads (De Silva 2007).
Fitness is considered a weight, U, that transforms a genotypic frequency at one age into a frequency at another and higher age.
The A frequency at position 51 reaches 90%, which is noticeably higher than in human regions.
For a given level of muscle activation there exists a frequency at which the maximum speed is attained.
AID-dependent mutations are found in the Ig loci at a frequency at least two orders of magnitude higher than in the remainder of the genome.
Nevertheless, simulations show that the human cleavage regions have significantly higher A frequency at position 51 (~80%) than random sequence with identical nucleotide composition (not shown).
So, the trick Mourou and Strickland figured out is to separate those out, so the amplifier has to deal with only a few frequencies at a time.
Statistical research suggests that tides of this level are to be expected at a frequency of at least once in 300 years.
