An entry at position (i j) marks the compatibility of labels for substructure node i and molecule atom j.
This is given by: (1) H (I, J ) = 1 | I | | J | ∑ i ∈ I, j ∈ J (a i j − a I j − a i J + a I J ) 2 where a ij is the entry at position ij in the sub-matrix (I, J), a iJ is the mean of the ith row, a Ij is the mean of the jth column and a IJ mean of the whole sub-matrix.
This is defined by: (3) H v (I, J ) = ∑ i ∈ I, j ∈ J (a i j − a I j − a i J + a I J ) 2 ∑ i ∈ I, j ∈ J (a i j − a i J ) 2 where a ij is the entry at position ij in the sub-matrix (I, J), a iJ is the mean of the ith row, a Ij is the mean of the jth column and a IJ is the mean of the sub-matrix.
Q i is the quantization table entry at position i.
Finally, the letter at position i is replaced by a.
We represent this phenotype as a binary vector of length 124 whose entry at position i indicates viability if sulfur source i is the sole sulfur source.
Such pseudoknots add one case in the computation of a matrix entry W i, j), which, as in the Zuker algorithm, contains the optimal energy of a substructure starting at position i and ending at position j.
By S i, j we denote the sub-sequence of S starting at position i and ending at position j.
The alignment is built by filling each entry M [ i, j, (α i, β j )] of a dynamic programming matrix M, where i and j are positions of G A and G B respectively, and (α i, β j ) enumerates the possible pairs of nodes that can be found in G A at position i, and in G B at position j, respectively.
In the entry-level position I eventually took, I was working with younger, boozing people.
