The fractional variation of occurrence (FVO) was used to determine and compare the strengths of the periodicities among the various motifs [35].
After that, they revealed the resizing by investigating the periodicity correlation among pixels.
Of broader significance were Berg's findings on the periodicity of reproduction among fishes and the influence of climatic variations on migratory species.
Three of the chalcogens (sulfur, selenium, and tellurium) were part of the discovery of periodicity, as they are among a series of triads of elements in the same group that were noted by Johann Wolfgang Döbereiner as having similar properties.
Lithium, sodium, and potassium were part of the discovery of periodicity, as they are among a series of triads of elements in the same group that were noted by Johann Wolfgang Döbereiner in 1850 as having similar properties.
The answer to this question is thought to depend on whether the chemical periodicity seen to occur among the elements has an underlying truth, effectively hard-wired into the universe, or if any such periodicity is instead the product of subjective human interpretation, contingent upon the circumstances, beliefs and predilections of human observers.
This study provides descriptive data on the periodicity in HIV seropositivity among migrants entering Kuwait predominantly from South-Asian countries, wherein, HIV epidemic is flaring-up recently [ 22].
The diffraction pattern consists of a periodic distribution with a periodicity reciprocally related to the raster periodicity.
At this cycle maximum, a 30 40 day periodicity is found to be dominant among the variations in ¯¯¯B, and this periodicity is found in ¯¯¯A during almost throughout the period 1986–1994.
On the other hand, we can not exclude that the observed eccDNA pattern could arise from some unknown, less abundant subfamily of VicTR-A repeats with already developed HOR periodicity which we did not detect among the cloned sequences.
