Human reproductive ecology to aid infant survival and growth. Lactational strategies vary cross-culturally, but can typically be defined by sibling sets and sex ratios, frequency of nursing, entire lactational duration, and milk composition. Milk is composed of my bioconstituents, but only a few will be outlined here. In the first days of puerperium, the first milk is thick and yellowish, also called colostrum. For weeks after that, mature milk is expressed and it has been shown that fetal-mammary gland signaling occurs even before birth in determining milk type and concentrations based on the fetus sex. Colostrum plays an important role in establishing the
Sesquilinear form of a complex Hermitian form is a Hermitian matrix. A complex Hermitian form applied to a single vector is always real. One can show that a complex sesquilinear form is Hermitian iff the associated quadratic form is real for all . A complex skew-Hermitian form (also called an antisymmetric sesquilinear form), is a complex sesquilinear form such that Every complex skew-Hermitian form can be written as times a Hermitian form. The matrix representation of a complex skew-Hermitian form is a skew-Hermitian matrix. A complex skew-Hermitian form applied to a single vector is always pure imaginary.
