Gain and phase margins are widely used stability indices of feedback control systems; although they are both considered explicitly only from the analysis point of view, the phase margin alone is usually considered in the design stage.
The control strategy is aimed at reducing vehicle speed before a potentially dangerous situation is reached, in contrast with widely used stability control systems that only react once loss of control by the driver is imminent.
To ensure we were studying gene expression in viable cells, we sought a time point when differences in the intrinsic myofibroblast phenotype could be assessed independent of cell death; we used stability of ribosome loading onto RNA as the viability metric.
A subsequent study used stability rather than agreement as termination criteria for Delphi [ 13].
Prill et al. [ 5] used stability as a criterion to discern network motifs and their organizing principles, and synthetic biologists are beginning to pay close attention to the stability of their artificial networks [ 6].
In addition, from the two used stability indicators on LDA, top-means favours microarray features (e.g., 17 to 3 for the u.i top-means), and top-20 favours image features (e.g., 2 to 18 for the u.i top-20).
