Although the design of DNA tiles has been optimised for efficient and specific self-assembly, assembly errors occur so often that applications for molecular computation remain limited. We propose the use of an enveloped tile consisting of a DXbase tile that carries a protector tile to suppress erroneous tile assembly. The design of the enveloped tile promotes the dissociation of the protector t...

We investigated tree textures starting from art historical sources describing the complicated appearance of trees, proceeding with an empirical survey using computer vision techniques, concluding with an overview of physical factors. Our main question was: Which perceptual, image statistical and optical phenomena primarily determine the appearance of trees and how are these phenomena related? T...
