Sentence examples for persistent periodicity from inspiring English sources

The comparison for the period 1100 1330 UT of TEC fluctuations along paths GPS7/KIRU, GPS9/KIRU with magnetic variations at KIR and EISCAT-derived ionospheric density N e in the lower ionosphere, shows the occurrence of persistent periodicity in all these parameters (Fig. 2).

Lack of prophages in chromosomes with persistent periodic signal suggests that the sequence periodicity and concomitant DNA curvature could play a role in protecting the chromosomes from integration of phage DNA.

Moreover, chromosomes that contain prophages tend to have weaker or less persistent sequence periodicity, suggesting that the periodicity and concomitant DNA curvature could also play a role in protecting the chromosome from phage integration.

Integrated prophages can comprise up to 10 20% of the chromosome size [ 25], and additions of such an amount of non-periodic DNA into a chromosome with otherwise persistent sequence periodicity could decrease the values of the Max2, Max3, and MaxMax indices.

It is possible that rigid sections of the nucleoid are less susceptible to phage integration, and chromosomes with persistent sequence periodicity are (partially) protected from phage integration.

We study the recently presented group sunspot number series and show that a persistent 22-year periodicity exists in sunspot activity throughout the entire period of about 400 years of direct sunspot observations.

Accordingly, a persistent 22-year periodicity in sunspot activity gives strong evidence for the existence of such a relic magnetic field in the Sun.

There are a few chromosomal sequences that do not fit the general pattern described above and contain a predicted prophage despite exhibiting a relatively persistent A-tract periodicity.

A feasible solution to this problem is to implement a semi-persistent scheduling [39] where the signaling check periodicity is extended (up to several seconds) without taking into account the licensed channel state.

Simulations suggest the evolutionary rate signatures are a combination of surface transport mechanisms, which are occurring with irregular periodicity but over longer distances across YNP, and on a relatively slow but persistent hydrothermal "conveyer" that would drive dispersal of chemotrophic communities through a YNP subsurface biosphere.

The FAA during habituation, as well as the persistent FAA during replacement, indicates that FAA might be driven by a FEO with a periodicity of 24 h but which does not depend on signals of either hunger or nutritional origin.
