An overlapping gene (or OLG) [1] [2] is a gene whose expressible nucleotide sequence partially overlaps with the expressible nucleotide sequence of another gene. [3] In this way, a nucleotide sequence may make a contribution to the function of one or more gene products.
Non-overlapping generations are found in species in which the adult generation dies after one breeding season. If a species for instance can only survive winter in the juvenile state the species will automatically consist of non-overlapping generations. The bee Amegilla dawsoni, an example of a species with non-overlapping generations
The two methods are also compared in Figure 3, created by Matlab simulation. The contours are lines of constant ratio of the times it takes to perform both methods. When the overlap-add method is faster, the ratio exceeds 1, and ratios as high as 3 are seen. Fig 3: Gain of the overlap-add method compared to a single, large circular convolution.
For example, when = and =, Eq.3 equals , whereas direct evaluation of Eq.1 would require up to complex multiplications per output sample, the worst case being when both and are complex-valued. Also note that for any given M , {\displaystyle M,} Eq.3 has a minimum with respect to N . {\displaystyle N.} Figure 2 is a graph of the values of N ...
The overlap-add method involves a linear convolution of discrete-time signals, whereas the overlap-save method involves the principle of circular convolution. In addition, the overlap and save method only uses a one-time zero padding of the impulse response, while the overlap-add method involves a zero-padding for every convolution on each ...
In contrast to interference as described above, increasing overlap of tests only decreases their efficacy. In the medical setting, diagnostic validity is increased by combining tests of different modalities to avoid substantial overlap, for example in making a combination of a blood test, a biopsy and radiograph.
“There will be some cross-protection among two influenza A strains, for example, H1N1 and H3N2,” Schaffner adds. ... but there's still a lot of overlap, says Sood.
Example of two-voice overlap; if the lower voice went only to B, that would not constitute overlap. A related phenomenon is "voice overlapping," where the voices do not cross per se, but they move together, and the lower voice passes where the upper voice was (or vice versa). For example, if two voices sound G and B, and move up to C and E.
