t (redirected from Crossed the T)

T, 20th letter of the alphabet. It corresponds to the Greek tau. It represents the unvoiced dental or, as in English, the alveolar stop. The diagraph th represents the characteristic English interdental fricative, voiced in this, voiceless in thing. For modern misapprehensions concerning older signs for the fricative, see the letter Y.

thyroxine

 or l-tetraiodothyronine or T₄

One of the two major hormones (along with the closely related l-triiodothyronine, or T₃) secreted by the thyroid gland. Its principal function is to stimulate oxygen consumption and thus metabolism in all cells and tissues in the body. Thyroxine is formed by the addition of iodine to the amino acid tyrosine while the latter is in a protein-bound form. Thyroxine secretion is excessive in hyperthyroidism and deficient in hypothyroidism.

T - 1. True. A Lisp compiler by Johnathan A. Rees in 1982 at Yale University. T has static scope and is a near-superset of Scheme. Unix source is available. T is written in itself and compiles to efficient native code. Used as the basis for the Yale Haskell system. Maintained by David Kranz <kranz@masala.lcs.mit.edu>. Latest version: 3.1. ftp://ftp.ai.mit.edu/pub/systems/t3.1. A multiprocessing version of T is available ftp://masala.lcs.mit.edu/pub/mult. Runs on Decstation, SPARC, Sun-3, Vax under Unix, Encore, HP, Apollo, Macintosh under A/UX. E-mail: <t3-bugs@cs.yale.edu> (bugs). E-mail: <t-project@cs.yale.edu>.
