Since the first edition of this book in 1999 the field of gene therapy has been the arena both for major advances that justified the early hopes placed in the concept, and for ever-present impatience with the slowness of overall progress. On the positive side, gene therapy obtained its first brilliant success, though not where most efforts were ...

PEI formalism has been designed to reason and develop parallel programs in the context of data parallelism. In this paper, we focus on the use of PEI to transform a program involving dense matrices into a new program involving sparse matrices, using the example of the matrix-vector product.

Polvnucleotide analogs with PEI or PEI/polyethyloxazoline backbones
Journal of Polymer Science: Polymer Symposia, 1986AbstractThe synthesis and characterization of uracil‐ and thy mine‐containing polynucleotide analogs with a linear polyethylenimine backbone is described. Hypochromicity is observed for these analogs in DMSO and in DMSO/H2O solutions and found lo increase as the percent water increases.

Reduction is one of the major issues in data parallel languages: it can be defined as a rule of program refinement. This article presents a theoretical framework, called Pei, the foundation of a formalism for parallel programming, where this rule can easily be expressed and applied.

Transformation techniques in Pei
1995This article presents a few examples of program transformation strategies in the language Pei [Vio94]. Three strategies are developed: a simplification of the communications, the introduction of broadcasts by removing recursion from data field definitions, and the introduction of a reduction operator.

Communications of the ACM, 1963
M. L. Pei [ Comm. ACM 5 , 10 (Oct. 1962)] gave an explicit inverse for a matrix of the form M + δI , where M is an n -square matrix of ones and δ is a nonzero parameter.
