Sentence examples for point interaction from inspiring English sources

For CADSS, a mixed model analyzed change from baseline, with treatment/dose, period, time point and treatment/dose by time point interaction as fixed effects, with subjects nested within sequence as a random effect and baseline values as a covariate.

This can be considered as an abstract version of the well known result for the perturbation by a point interaction of the Laplace operator in L2(R3).
