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
Harmonic Maass form combinatorial, arithmetic, or geometric generating functions. Regularized theta lifts of harmonic Maass forms can be used to construct Arakelov Green functions for special divisors on orthogonal Shimura varieties. A complex-valued smooth function on the upper half-plane is called a weak Maass form of integral weight (for the group ) if it satisfies the following three conditions: If is a weak Maass form with eigenvalue 0 under formula_4, that is, if formula_5, then is called a harmonic weak Maass form, or briefly a harmonic Maass form. Every harmonic Maass form of weight has a Fourier expansion of the form where ,
