"resistive effects... causing ELMs we seeing... improved model... change profiles of plasma... get rid of ELMs... plasma as a fluid. In general, you can’t have a model that includes all of physics in it. It would be too hard to solve. You want a model that is simple enough to calculate but complete enough to capture the phenomenon you are interested in. Andreas found that resistivity is one of the physical effects that we should include in our models"
