Source: WordNetAssuming that the matrix W is a primitive matrix ( irreducible and aperiodic ), then after very many generations only the eigenvector with the largest eigenvalue will prevail, and it is this quasispecies that will eventually dominate. Source: Internet
In order that the quasicrystal itself be aperiodic, this slice must avoid any lattice plane of the higher-dimensional lattice. Source: Internet
An irrational number stays aperiodic (with an infinite number of non-repeating digits) in all integral bases. Source: Internet
Around the same time Robert Ammann created a set of aperiodic tiles that produced eightfold symmetry. Source: Internet
As further aperiodic sets of tiles were discovered, sets with fewer and fewer shapes were found. Source: Internet
DNA was later discovered, and, although not crystalline, it possesses properties predicted by Schrödinger—it is a regular but aperiodic molecule. Source: Internet
