Artem writes about what I could describe as a 'decorative mathematical model'. A decorative model is what you find in certain biological journals where the mathematical model is not meant to drive the biological experiments nor to derive a new understanding of the biological data. I am not sure that the paper he describes fall in this category (I have not read the paper in detail) but his observations are useful to any mathematical biologist: a complicated mathematical model with lots of parameters produced after the experiments have been performed is unlikely to be too useful.
