Repeat the dynamics using a temperature simulation of 80°C. Compare these results with the results from Studies 3. la and 3.2a. An interesting question for the student to contemplate is whether the use of the alternative variegated cell, abab, would produce different results in these studies. Reach a conclusion as to whether the more detailed aabb cell has any significant differences from the uniform cell employed in Applications 1 and 2. The future use of the variegated cell may be important when different features of the same molecule are to be encoded. More on this in later chapters.

Figure 4 The possible variegated cells, (a) Possible occupants with two different types of edges allowing for different rules for the edges, (b) Possible occupants with three different types of edges hence possibly different rules for the edges, (c) Possible occupants with two different types of edges hence different rules for the edges.

Another study on these variegated cells depicting an amphiphile revealed a temperature effect on the critical micelle concentration (cmc) that was minimal at about PB(W) = 0.25. Experimentally, the minimal cmc value occurs at about 25 °C.64 The onset of the cmc was also modeled and shown to be dependent on a modestly polar fragment of the amphiphile.
