Jiao Y, Ma L, Strickland E, Deng XW. (2005) Conservation and divergence of light-regulated genome expression patterns during seedling development in rice and Arabidopsis.
Beam profiling was performed to measure the effective spot size and divergence of the light exiting the optrode tips.
When the optical wave reflects off the sample surface and propagates to the camera plane, the sample image will blur due to the divergence of the light beam.
A similar transition also exists in the PT-symmetric optical system and results in the disappearance of the stable propagation mode (without decay or divergence of the light intensity), therefore the optical feedback between gain and loss medium must be carefully balanced.
As for eye movement, he made his mark with work on the divergence and convergence of light rays entering the lens, as well as on the involuntary movements the eyes make when scanning a line of type.
The grating decreases the divergence of the laser light by a factor of 25, eliminating the need for bulky, expensive mirrors and lenses.
Lack of detectable genetic divergence in light of evolutionary divergence in swamp sparrows suggests that selection is likely to be strong in tidal marsh populations with adaptation occurring relatively quickly and possibly in the presence of gene flow [20], [23].
The current trihelix family, expanded in angiosperm, seems to be a common ancestor of land plants with a large functional divergence associated with regulation of light, stress, and a series of developmental programmes.
This study provides a consistent view on gene evolutionary traits across a large set of vertebrate, arthropod, and fungal species spanning millions of years of divergence and sheds light on several fundamental principles of eukaryotic gene repertoire evolution.
The two last groups, for which the contribution to total LAI exceeded 60%%, showed divergences between computed values of light sharing and the theoretical approach that assumes well-mixed canopies (Fig. 3F, slope of the linear regression = 0.97, R = 0.42).
