In the time-stepping process of the proposed method, the column vector containing the spatially sampled field values is updated by multiplying it with an iteration matrix, which is written in a matrix-exponential form.
In each method, the column temperature was maintained at 40 °C, and the analytes were monitored at 254 nm.
For long chain acyl-CoAs, the same column and flow rate were used in gradient mode with the following method: the column was equilibrated with 60% mobile phase A (CH3CN/H2O (98:2 v/v, containing 50 mM ammonium formate).
The flow rate was 200 μl/min in gradient mode with the following method: the column was equilibrated with 98% mobile phase A (CH3CN/H2O 98:2 v/v, containing 50 mM ammonium formate).
In Table 2, the first column represents the methods, the second column represents the accuracies associated with each method.
Unlike the Nyström method, the Column-Sampling method approximates the eigenpairs of G by using the SVD of C directly.
First, the list of the eight application areas, drawn from MeSH Terms (Medical Subject Headings), was used for characterising the twenty eight methods (the first column of Table 3).
Second, the eight project life cycle stages, which were drawn from Royston [ 31], were used for characterising the twenty eight methods (the second column of Table 3).
Difference values are the result of subtracting the mean value for the method in the row from the mean value for the method in the column (column mean-row mean).
'+', '−' and 'N' symbols indicate that the method in the corresponding row is significantly better than, worse than or not different (P<0.05) from the method in the column.
