Colostrum immune cells (as lymphocytes) and many antibodies such as IgA, IgG, and IgM. These are some of the components of the adaptive immune system. In preterm infants some IgA may be absorbed through the intestinal epithelium and enter the blood stream though there is very little uptake in full term babies. This is due to the early "closure" of the intestinal epithelium to large molecule uptake in humans unlike the case in cattle which continue to uptake immunoglobulin from milk shortly after birth. Other immune components of colostrum include the major components of the innate immune system, such as lactoferrin,
P-adic modular form is invertible at ("E",ω). The "p"-adic modular form "f" now takes values in "R" rather than in the complex numbers. The "p"-adic modular form also has to satisfy some other conditions analogous to the condition that a classical modular form should be holomorphic. Overconvergent "p"-adic modular forms are similar to the modular forms defined by Katz, except that the form has to be defined on a larger collection of elliptic curves. Roughly speaking, the value of the Eisenstein series "E" on the form is no longer required to be invertible, but can be a smaller element of "R". Informally the
