Replication of Arbitrary Hole-Free Shapes via Self-assembly with Signal-Passing Tiles

In this paper, we investigate the abilities of systems self-assembling tiles which can each pass a constant number signals to their immediate neighbors create replicas input shapes. Namely, work within Signal-passing Tile Assembly Model (STAM), and provide universal STAM tile set is capable creating unbounded numbers assemblies shapes identical those assemblies. The be arbitrary 2-dimensional hole-free This improves previous shape replication results in self-assembly that required models multiple assembly stages and/or bins were required, could replicated more constrained, as well version result represented at scale factor 2.
