Often in industrial experimentation there are a large number of factors to be considered, even though only a few are important (effect sparcity). Several techniques have been proposed for screening the important factors, but each has its limitations. We propose a new adaptive screening technique using a genetic algorithm by construction of an optimal supersaturated design from the Hadamard matr...

Thus, so-called growth factors that affect only the frequency of mitosis are not really growth factors. I shall advance two hypotheses: that the normal adult ratio of cell births to cell deaths is maintained by the activity of a factor or fac...
