1. As a result, the split normal density is non-symmetric and uni-modal. 2. The split normal density is completely characterized by three parameters, the mode, variance and skewness. 3. Bare-sphere critical masses at normal density of some actinides are listed in the following table. 4. Except for normalization constant, the above equation completely determines the normal density function for " X ". 5. Corn is planted at about twice the normal density to create the visual effect of a wall. 6. A bare critical mass of plutonium at normal density and without additional neutron reflector material is roughly. 7. Cells with normal density of DNA are diploid cells, which characterize the relatively benign " indolent " tumors. 8. The grey curve is the true density ( a normal density with mean 0 and variance 1 ). 9. A bare critical mass of plutonium at normal density and without additional neutron reflector material is roughly 10 kilograms. 10. This density results from joining the two halves of corresponding normal densities with the same mode but different variances.
