Immaculate Conception–Reply

Digital Fidelity in an Age of Immaculate and Pernicious Reproduction

Just because politicians lie doesn't mean it's not important to vote. Digital fidelity may be an impossible ideal but that doesn't mean there aren't better principles than others by which to fail. Taking NMAA's experience digitizing over 4,000 images from its collection and re-presenting them in print, on disc and in the ether, the author propeses some guidelines for better failures in the future.

Infertility treatment for HIV-positive couples: far from immaculate conception.

Journal of Family Planning and Reproductive Health Care 2003: 29(4) Introduction The issue of infertility diagnosis in human immunodeficiency virus (HIV)-positive couples is medically and ethically complicated. Studies show that although many in vitro fertilisation (IVF) units in the UK screen patients for HIV, only a handful are prepared to treat couples if one or other partner tests positive ...

Multiplicative structures of the immaculate basis of non-commutative symmetric functions

The immaculate basis of the non - commutative symmetric functions ( Extended Abstract )

We introduce a new basis of the non-commutative symmetric functions whose elements have Schur functions as their commutative images. Dually, we build a basis of the quasi-symmetric functions which expand positively in the fundamental quasi-symmetric functions and decompose Schur functions according to a signed combinatorial formula. Résumé. Nous introduisons une nouvelle base des fonctions symé...

Dual immaculate creation operators and a dendriform algebra structure on the quasisymmetric functions

The dual immaculate functions are a basis of the ring QSym of quasisymmetric functions, and form one of the most natural analogues of the Schur functions. The dual immaculate function corresponding to a composition is a weighted generating function for immaculate tableaux in the same way as a Schur function is for semistandard Young tableaux; an “immaculate tableau” is defined similarly to a se...
