The age-frequency distribution showed a typical shape when the recruitment was not constant; the unimodal distribution pattern in the age structure mainly identifies older individuals (Sloan & Robinson 1984).
Unexpectedly, as was the case with the thermoset compositions shown earlier, it was discovered that as the MW of the low MW EPDM fraction was varied and increased to about 50 (ML [1+4] @ 125[degrees]C), the instant TPVs had an improved balance of properties comparable to TPVs comprising conventional bimodal and unimodal high molecular weight oil-extended EPDM rubber.
Words were selected for inclusion in these word groups if they generated strong unimodal sensory images in the respective word category.
The percent frequency of the oocyte diameters was unimodal, with a mode of 1.
Adding a distribution assumption such as unimodal to the constraints in (15) or (16) means that we optimize over a smaller set and thus obtain tighter bounds than the general bounds.
Species richness does not reach its peak in a single latitudinal band, nor is the pattern unimodal.
In contrast, the controls had unimodal distribution with a single peak at < 10 micrometers.
Cabot Corporation has obtained a patent for a polymeric product comprised of at least one polymer and a blend of two or more different types of fillers having different physical, chemical, or morphological properties, wherein the blend of fillers have a unimodal pore size distribution and/or a unimodal aggregate size distribution, wherein the two or more different types of fillers each have a different DBP and the blend has a DBP that is lower than an average DBP of each filler present based on each individual DBP and amount of each filler present or wherein the two or more different types of fillers each have a different crushed DBP and the blend has a crushed DBP that is lower than any crushed DBP of each individual filler present.
For instance, if F{Y,X) is a unimodal Gaussian distribution, the conditional mean, E(Y/X;[theta]), coincides with the linear regression estimate.
Species diversity (including E, richness, and Shannon-Wiener Index) predicted by the MDE first increased and then decreased after reaching their maximum, showing a unimodal pattern against altitude.
To gain insight into whether a reduction in population size has occurred in the past, we examined the distribution of the observed number of differences between pairs of haplotypes, The distribution is usually multimodal in samples drawn from populations at demographic equilibrium, as it reflects the highly stochastic shape of gene trees, but is expected to be unimodal in populations that have undergone a recent demographic expansion (Rogers and Harpending, 1992).
