I just wrote a few functions that should theoretically allow you to take an array, chunk it by rows or columns, and then stack them in the other dimensions,...
Block copolymers spontaneously self-assemble into well-defined nanoscale morphologies. Yet equilibrium assembly gives rise to a limited set of structures. Non-equilibrium strategies can, in principle, expand diversity by exploiting self-assembly’s respo
This entails adding several more arrays to the state. In particular, our formulation considers branches separately when finding the optimal CTD configuration, whereas normally coaxial stacks are optimised by trying every possible split point explicitly, in a loop. A split point (also called a pivot...
