They found that the optimal stability of nongenetically transmitted variants across generations depends on environmental periodicity, with greater stability favored when fluctuations span a greater number of generations.
Wilkins Peak Member lithofacies stacking patterns record cyclic geomorphic responses to insolation and climate fluctuations, spanning an interval of 1.8 Ma.
Flying 36 kilometers high, BOOMERANG's 1.3-meter 1.3-meter zeroed in on microwave fluctelescopespanning just fractions of an angular degree.
Their singular nature suggests that they could be recent, possibly occurring during or since the period of complex temperature fluctuations spanning the last two major glaciations 130,000-13,000years ago [ 20].
In contrast, fluctuations spanning across an intermediate number of generations might select for enhanced evolvability at the population level, and might also lead to the maintenance of genetic variation (Turelli and Barton 2004; Meyers et al. 2005).
Laboratory tests are made on samples taken from the most critical fatigue details on a region of high stress fluctuation (mid span) and the same details at a stagnant region (supports location) and compared.
As shown in Figure 7A and 7B, significant fluctuations of the span distance can be observed in both the transverse distance (varying from 10 Å to 17 Å) and lengthwise distance (varying from 36 Å to 41 Å) of the system without InsP6, compared with the transverse (from 12 to 16 Å) and lengthwise (from 35 to 39 Å) distances of the system with InsP6.
It has been used in soybean to infer domestication history, usually including a bottleneck and a following effective population size fluctuation in the time span of thousand years (Lam et al., 2010).
Further, in order to improve the computational efficiency and reduce the memory demand, a new approach that combines the polynomial model, the proper orthogonal decomposition (POD) technique, and the B-spline surface interpolation technique, is proposed for generating the non-Gaussian wind pressure fluctuations on large-span roof structures.
The similarity of order parameters determined using spin relaxation and RDCs throughout the β-sheet demonstrates the absence of significant conformational fluctuations over timescales spanning up to six orders of magnitude (ns ms).
To this respect, only low-frequency wind speed fluctuations strongly correlated along the span are taken into account, neglecting the beneficial effects due to a loss of coherence or to higher frequency components.
