Carboxylesterases, a key factor in evaluating potential genotoxicity of Trinem antibiotics (2000)
Oliver, J., Naidoo, A., Vandin, L., Pugnaghi, F., Gatehouse, D., Comelli, R.
Sanfetrinem cilexetil, a hexetil ester of a Trinem antibiotic, does not induce micronuclei in rat bone marrow cells or induce DNA repair synthesis in rat hepatocytes following oral dosing. However,...

Chronic renal failure has been suggested as a risk factor for mitral annular calcification (MAC), a degenerative process of the mitral annulus. The objective of the present study was to define MAC...
The Accurate Evaluation of Polynomial Approximations to Library Functions (1982)
Bounds are derived on the absolute and relative errors resulting from the storage and evaluation of polynomial approximations having coefficients of constant or strictly alternating sign, and the...
An Error Analysis of the Modified Clenshaw Method for Evaluating Chebyshev and Fourier Series (1977)
The propagation of rounding errors in both Clenshaw's (or Goertzel's) original algorithm and Reinsch's modified form is analysed, and a criterion is deduced for choosing between them. Their practical...
Stable Methods for Evaluating the Points cos(i{pi}/n) (1975)
A variety of alternative methods for evaluating cos(iπ/n) for i= 0, 1,...,n are compared theoretically and experimentally, and the best ones selected on the basis of accuracy and the computational...
A Doubly-Adaptive Clenshaw-Curtis Quadrature Method (1972)
An automatic integration algorithm, based on the Clenshaw-Curtis method, is described which can adapt either the formula in use or the interval subdivision at any stage. Numerical tests demonstrate...
A Practical Strategy for the Clenshaw--Curtis Quadrature Method (1971)
The Clenshaw—Curtis method for numerical integration can be implemented with either repeated doubling of the order of the formula or successive refinement of the basic interval of integration. A...
The evaluation of definite integrals using high-order formulae (1971)
The use of high-order integration formulae in general-purpose library routines is widely discouraged in the literature. The reasons advanced for the recommended preference for the trapezoidal,...
Most numerical methods for producing approximate Chebyshev series solutions to ordinary differential equations lead to a system of algebraic equations for the coefficients, while the truncation error...
Inherent Instability in Systems of First Order Linear Differential Equations (1968)
The numerical integration of ill-conditioned initial and boundary value problems may be rendered ineffective by the propagation of truncation and rounding errors. This problem is analysed with...
