Ratios of mRNA transcript abundance between sample types are measures of biological activity. These measurements of differential gene expression are important to underpin new biological hypotheses and ...

Neural prostheses have recently shown considerable promise in proof-of-concept animal experiments 1,2,3,4,5,6,7,8,9 and in human clinical trials 10,11,12,13 for partially restoring motor output in ...

The application of experimental design methods to practical engineering problems is illustrated by an example involving road tests to measure how elevation affects octane requirements of automobiles.
