Sentence examples for modulation of the precession cycle from inspiring English sources

On the contrary, the ~20 bed cycle, which is correlated with the 405 kyr cycle assuming each chert-shale couplet as the ~20 kyr precession cycle, is modulated its frequency between ~18 beds and ~25 beds due to the frequency modulation of the precession cycle between 17 kyr and 21 kyr cycle (the wavelet spectra in Fig. 3(a); see also figure 6 of Ikeda et al., 2010a).

Gradual changes in absolute and relative abundance of the cyst species in these assemblages over several couplets depict a bundling pattern which is interpreted to reflect the modulation of the intensity of the precession cycle by the eccentricity cycle (100 ka).

These estimated durations for an individual chert-shale couplet are consistent with the 17 to 21 kyr duration of the precession cycle during Late Triassic to Early Jurassic (Berger et al., 1989).

Rather, their action is captured as a modulation of the cycle timescales.

Here we examine the general trend and nature of frequency modulation and amplitude modulation of the ~2 Myr eccentricity cycle computed by the orbital models.

These results demonstrate a role for GSK-3β in the modulation of G1 cell cycle progression.

The frequency modulation of ~2 Myr cycle will provide new constraints for the orbital models.

We measured thickness of individual chert bed throughout the sequence, and confirmed ~20 kyr precession cycle origin of chert-shale couplet based on biostrati-graphic ages.

A complete precession cycle requires 25,770 years, during which time the pole of the Earth's rotation follows a circular path across the celestial sphere that passes near several prominent stars.

The regulation of SOX4 affected the tumor proliferation via modulation of cell cycle.

The 9 archaeological levels comprise a relatively continuous record through a Milankovitch precession cycle (dry-wet-dry).
