Killer, integral

The Dirac delta function, very often used in quantum mechanics, is an infinitely tall but infinitely thin function, which is anathema to some mathematicians (it is called an improper function). In analogy to what the Kronecker delta does, the Dirac delta function could be called an "integral killer" because... 

Syk and ZAP-70 are early intermediates in the transduction of signals from immune receptors, including the B- and T-cell recqrtors for antigen, activatory natural killer-cell receptors, the mast cell and basophil receptor for IgE, and the widely distributed receptors for the Fc portion of IgG. Immune receptors control checkpoints in lymphocyte development and serve to integrate the responses of innate and acquired immunity.

Natural killer (NK) cells are non-B, non-T lymphocytes that are an integral part of the first line of defense in innate or natural immunity. These cells are considered large granular lymphocytes (LGLs) as they are larger than B and...
