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 ...

Figure 2: A schematic representation of the logical model of the aromatic amino acid pathway in yeast. We needed a way of representing prior biological knowledge in the computer, so we developed a ...

When conducting surveys, two kinds of nonresponse may cause incomplete data files: unit nonresponse (complete nonresponse) and item nonresponse (partial nonresponse). The selectivity of the unit ...

Editor’s note: This is part of a series called “The Day Tomorrow Began,” which explores the history of breakthroughs at UChicago. Learn more here. A field experiment is a research method that uses ...
