Diadenosine 5′,5‴-P 1 ,P 4 -tetraphosphate (Ap 4 A) hydrolase is the enzyme responsible for maintaining the intracellular level of the dinucleotide Ap 4 A, the function of which has yet to be established. The APAH1 gene encoding this Ap 4 A hydrolase has been mapped by fluorescencein situhybridization and PCR to human chromosome 9p13. Radiation hybrid panel...
A new random-error-correction code presented here is one of the most efficient two-error-correction codes. The new code can correct 2-bit random errors within twelve (12) consecutive bits while (15,7) BCH code [1] corrects two errors within fifteen (15) bits and Hagelbarger's code [2] corrects two errors within fourteen (14) bits. Although Peterson and Weldon's double-error-correcting (12,6) code...
Two new rapid adaption procedures are presented in this paper. The first one, Multi-Pattern Maximum Adaption Procedure, corrects all errors simultaneously, instead of one by one (Ref. 2-5), exactly to the unity of the worst dot product, X.W. The second one, Multi-Pattern Random Adaption Procedure, simultaneously adapts every pattern with undesired output to the unity of any one of the wrong dot products...
