Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry is a powerful tool for rapidly generating protein expression data (peptide and protein profiles) from a large number of samples. However, as with any technology, it must be optimized and reproducible for one to have confidence in the results. Using a classical statistical method called the fractional factorial design ...

We present a design of experiments (DOE) technique for microwave/millimeter wave flip chip characterization and optimization. Two optimization approaches, signal bump misalignment and transmission line compensation, are combined together for optimal performance for high frequency operation. First, the design of experiments method is presented and its advantages are emphasized. Then, the two tec...

Microarray technology is a powerful tool for generating expression data on a large number of genes simultaneously. However, as for any assay, it must be reproducible to give confidence in the results. Using a classical statistical method--the factorial design of experiments--we have assessed the effects of different experimental factors in our system. Significant effects on signal were seen whe...
