This algorithm uses a rational variant of the QR transformation with explicit shift for the computation of all of the eigenvalues of a real, symmetric, and tridiagonal matrix. Details are described in [1]. Procedures <italic>tred</italic>1 or <italic>tred</italic>3 published in [2] may be used to reduce any real, symmetric matrix to tridiagonal form. Turn(More)
BACKGROUND The Crabtree-negative yeast species Kluyveromyces lactis has been established as an attractive microbial expression system for recombinant proteins at industrial scale. Its LAC genes allow for utilization of the inexpensive sugar lactose as a sole source of carbon and energy. Lactose efficiently induces the LAC4 promoter, which can be used to(More)
DESCRIPTION The procedures QUINAT, QUINEQ, and QUINDF of Algorithm 507 [1] have been translated from ALGOL W into subroutines in 1966 American National Standard FORTRAN with only minor modifications. When using the original ALGOL W version of QUINAT with double or triple knots, it was necessary for the user to make a redefinition of some y-values(More)
