For instance, under reversephase conditions, a phenyl-derived

column matrix may produce a different elution profile (i.e., number of isomers separated) compared to an alkyl-derived

column matrix, due to the interactions involved in the retention mechanism of the respective columns [12, 16].

[TEXT NOT REPRODUCIBLE IN ASCII] U is the matrix of measured voltages; [??] is the

column matrix of measured currents; [??] is the

column matrix of unknown conductivities.

where A and B are tridiagonal matrices and b is

column matrix. It can written as

Compared with previous researches, which paid great attention to multiplex PCR or simplifying DNA extraction to improve the efficiency (Ali et al., 2011; Monden et al., 2014), the strategy of two- dimensional bulked DNA sampling (in a 10-row x 10-

column matrix) can save time and labor dramatically without any simplification.

where [v.sup.0.sub.j] is any particular solution of system (14), W is the null space matrix of [A.sup.*], such that [A.sup.*]W = 0 with 0 the null matrix, [A.sup.*.sub.j] is the row j of matrix W, and [rho] is a

column matrix of arbitrary real numbers.

with respect to a pseudo-orthonormal frame {O; [u.sub.1], [u.sub.2],..., [u.sub.2n+1]}, whose A is the normal formed skew-symmetric matrix and C is a (2n + 1) x 1

column matrix such that

The choice of the

column matrix in this case is dependent on the selected protein tag.

where [([N.sup.i.sub.b]).sub.dg] is a diagonal L x L matrix including the values of the axial forces of the ith beam; the symbol [(*).sub.dg] indicates a diagonal L x L matrix with the elements of the included

column matrix. The matrices [X.sup.i.sub.bz], [X.sup.i.sub.by], [X.sup.i.sub.hw] result after a[[rho].sub.p]roximating the derivatives of [m.sup.i.sub.byj], [m.sup.i.sub.bzj], [m.sup.i.sub.bwj] using appropriately central, backward, or forward differences.

where [[bar.a].sup.(s)]([xi]) denotes the

column matrix generated by the expansion coefficients of the transformed scattered field.

where [E.sub.scat] is the p x 1 single

column matrix, and [J.sub.eq] is the q x 1 total VECS single

column matrix, and is defined as,

Many readers are no doubt familiar with any of a number of commercial products which perform exactly this process (and the functions of lysis and wash buffers,

column matrix, and elution buffers are now made clear).

Let X be a

column matrix of data set: [??] = X - [bar.X] x [[??].sup.T], where [bar.X] is the mean of columns of X.
