With structural keys each position in the bit string corresponds to a pre-defined structure or molecular feature.
For instance, by using a key–lock analogy, two binary strings have a high affinity if they complement each other, that is, when the two strings are lined up, every "0" in one string corresponds to a "1" in the other, and conversely.
Each amino acid residue of a single window was encoded into a unitary bit string of length 20, where a bit was set (value = 1) if its position in the string corresponds to the position of the amino acid residue and zero otherwise [24].
Each bit in the string corresponds to a BNF rule with two options.
Each character of the quality string corresponds to one nucleotide of the sequence; thus the two strings should have the same length.
Each element in the string corresponded to up to 40 residues and was represented by a bead (coarse scale) and a spherical Gaussian.
The presence of an ortholog in another genome is represented as a 1 and the absence as a 0. Each position of a string corresponds to a respective genome.
In the problem of spectral analysis of a system of branching strings, we have the following correspondence: the strings correspond to the edges of the graphs and the points of the junctions of the strings correspond to the interior vertices.
Generally, different path strings correspond to different perceptual groups as the back-end DOM tree structure decides the front-end page layout.
Splitting and recombination of strings correspond to particle emission and absorption, giving rise to the interactions between particles.
