In the past decade there has been considerable discussion about the policy of the early selective screening of children at high risk of suffering from handicapping conditions which are not apparent at birth. This policy was advocated by Lindon (1961) and Sheridan (1962), who felt that universal screening of all infants was not practicable at that time. Sheridan in particular considered that it ...

This paper proposes a novel statistical evaluation model for automated protein NMR sequential resonance assignment. It can be bound to any assignment program and provides confidences for the whole output assignment and each individual mapping. A simulation study on a set of four proteins shows that the statistical evaluation results are informative.

The partial retention of the disperse phase in the ultrafiltration of a monodisperse system through an isoporous filter is interpreted on a statistical basis, and a simple expression for the sieve constant is evaluated in terms of the calibrated membrane porosity and the particle size. Curves calculated from this expression are in reasonable agreement with experimental data for the ultrafiltrat...
