Sentence examples for optical ratio from inspiring English sources

Schmitz and Motani [ 27] introduced the optical ratio (OPT) as a descriptor of light sensitivity, on the basis of earlier work by Hughes and Land [ 36, 37].

We assessed differences in eye shape by means of morphological proxies of the optical ratio and also multivariate analyses (PCA, Figures 3a-c, and DA).

The eye morphology of nocturnal reef teleosts is characterized by a syndrome that indicates better light sensitivity, including large relative eye size, high optical ratio and large, rounded pupils.

We tested for differences in the optical ratio, the ratio of the square of optical aperture and the product of retinal diameter and posterior nodal distance (OPT, [ 27, 28, 38], please also see Methods) with several sets of morphological proxies.

Diurnal teleost reef fish, released from the stringent functional requirements of dim-light vision have much higher morphological and optical diversity than nocturnal species, with large ranges of optical ratio, depth of focus, and lens accommodation.

On the basis of these loadings species with high optical ratio, i.e., the ratio of the square of lens diameter and the product of eye diameter and axial length should plot in the bottom right quadrant of morphospace.

Then, these optical ratios show relatively simple behaviors, and can be useful though restricted to simple geometrical shapes.

The observed patterns for relative eye size and optical ratios indicate that differences between nocturnal and diurnal eye morphology become less pronounced for absolutely larger eyes.

The complex strain-optical ratio and the complex Young's modulus of a polyarylate with a low molecular anisotropy, PAr1, were measured around the glass-to-rubber transition zone.

The data were analysed with a modified stress-optical rule: The Young's modulus and the complex strain-optical ratio were separated into two component functions (denoted by G and R) for which the ordinary stress-optical rule held well individually.

The purity of DNA was considered significant for an optical density ratio (OD ratio) OD 260/OD 280 of approximately 1.8 and less than 2.0.
