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 ...

Science lessons have traditionally given pupils the opportunity to learn by carrying out a variety of practical experiments. Examples include: • Pupils learning how a chemical reaction can be produced ...

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 ...

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 ...

The following data set records the results of an experiment to determine how the yield of a chemical reaction varies with temperature and amount of a catalyst used. data Experiment; input Temperature ...

Researchers from Johns Hopkins University used a series of sophisticated experiments to test a philosophical idea. They found that it is nearly impossible to separate an object’s true identity from ...

Educational research indicates that error reflection, especially reflection on incorrect examples, has a positive effect on knowledge acquisition. The benefit of ...
