(ii) The two linear P-v regimes correspond to dramatically different kinetic modes of GB motion: the linear regime at low driving forces has the characteristic behavior of

Markov chain but non-homogeneous AR models can reproduce the characteristics of these variations. For example, Figure 6 shows that the fitted model can reproduce both the

Typical sparsification methods use approximate linear dependence conditions to evaluate whether, at each time step n, the new candidate kernel function κ( · , u n ) can be

The second idea which turned out not to be pertinent was generalizing the idea of degree distribu- tion for each simplex order: what is the probability for a vertex to be
