ordinary 1-level container with value typedouble. It is equivalent toExpression{f, c1[0], c2[0]}. Soex0essentially behaves likevector<double>. You can read the first value of the container (and finally trigger an evaluation of the function) using eitherex0or the original expression like ...
Scientific evidence suggests that being “D-ficient” may increase the risk of various chronic diseases, from osteoporosis to heart disease, some cancers, and even multiple sclerosis. Vitamin D is a factor in the expression of more than a thousand genes throughout the body. If those genes are...

To this end, integrase-deficient lentiviruses carrying a 12-RSS, a 23-RSS, or a SJ were used to transduce REH cells, a B cell line derived from an ALL patient (Rosenfeld et al., 1977) where RAG expression is at physiological levels (Bories et al., 1991). 48 h after transduction, ...
[0015] In a further embodiment, the invention is a method of making a substantially homogenous cell population which co-express CD49c and CD90 by culturing a source of the cell population at a seeding cell density of less than about 75,000 cells/cm2 under a low oxygen condition to produc...
