We consider the common-knowledge paradox raised by Halpem and Moses: common knowledge is necessary for agreement and coordination, but common knowledge is unattainable in the real world because of temporal imprecision. We discuss two solutions to this paradox: ( 1) modeling the world with a coarser granularity, and (2) relaxing the requirements for coordination. @ 1999 Elsevier Science B.V. All...
We report on a 2 1/2 year old girl who is dysmorphic, developmentally delayed, and mosaic for an unbalanced, de novo translocation between chromosomes 3 and 15. The karyotype from peripheral blood lymphocytes is 46,XX (50) and the karyotype from skin fibroblasts is 46,XX (28)/46,XX,der(15)t(3;15)(q11;p11) (23). The mechanism for the generation of this unbalanced, de novo translocation is discus...

In 1987, Cover proposed an interesting problem in the simple relay channel [1] as shown in figure 1. In this channel, pp(yy11,yy22|xx) = pp(yy11|xx)pp(yy11|xx) and the channel from YY11 to YY22 does not interfere with YY22. Denote the rate from YY11 to YY22 as CC00. The critical value of CC00 such that CC(CC00) first equals CC(∞) is determined in this paper. In order to achieve this, a new deco...
Lipases catalyze hydrolysis and synthesis of triacylglycerols. These enzymes,especially the microbial ones, have wide commercial and industrial usage. Bacillus subtilis <span style="color: ...
The 46, XX disorder of sex development (DSD) is a rare form of sex reversal in infertile men, that was first described by la Chapelle et al. in 1964 and occurred 1:20 000 in newborns. Usually, it is caused by unequal crossingover between X and Y chromosomes during meiosis in the father, which results in the X chromosome containing the normally-male SRY gene. When this X combines with a normal X...
The 46 XX, testicular sex differentiation disorder, or XX male syndrome, is a rare condition detected by cytogenetics, in which testicular development occurs in the absence of the Y chromosome. It occurs in 1:20,000 to 25,000 male newborns and represents 2% of cases of male infertility. About 90% of individuals present with normal phenotype at birth and are generally diagnosed after puberty for...
A baby girl with some of the stigmata of Down's syndrome was found to be a mosaic with three different cell lines: 45,XX,-13,-21,+t(13q21q)/(46,XX/46,XX, -21,+t(21q21q). The chromosome rearrangements detected in this patient appear to have arisen de novo. In the normal cell line the terminal end of the p arm of one chromosome 21 is thought to have been damaged. It seems probable that this is re...
BACKGROUND Chromosomal abnormalities contribute substantially to reproductive problems, but the role of environmental risk factors has received little attention. OBJECTIVES We evaluated the association of polychlorinated biphenyl (PCB) and dichlorodiphenyldichloroethylene (p,p'-DDE) exposures with sperm sex-chromosome disomy. METHODS We conducted a cross-sectional study of 192 men from subf...
