    The moving ranges involved are serially correlated so runs or cycles can show up on the moving average chart that do not indicate real problems in the underlying process. [ 2 ] : 237 In some cases, it may be advisable to use the median of the moving range rather than its average, as when the calculated range data contains a few large values ...

    Super PI finishing a calculation of 1,048,576, or 2 20 digits of pi. Super PI is a computer program that calculates pi to a specified number of digits after the decimal point—up to a maximum of 32 million.

    The ability to fine-tune pi stacking interactions would be useful in numerous synthetic efforts. One example would be to increase the binding affinity of a small-molecule inhibitor to an enzyme pocket containing aromatic residues. The effects of heteroatoms [7] and substituents on pi stacking interactions is difficult to model and a matter of ...
