This paper presents a high-order double-sampling single-loop modulation analog-to-digital (A/D) converter. The important problem of noise folding in double-sampling circuits is solved here at the architectural level by placing one of the zeros in the modulator’s noise transfer function at half the sampling frequency instead of in the baseband. The resulting modulator is of fifth order but has t...

We present a Bayesian sampling algorithm for parameter estimation in a discrete-response model, where the dependent variables contain two layers of binary choices and one ordered response. Our investigation is motivated by an empirical study using such a double-selection rule for three labour-market outcomes, namely labour-force participation, employment and occupational skill level. It is of p...

BACKGROUND Developing sampling strategies to target biological pests such as insects in stored grain is inherently difficult owing to species biology and behavioural characteristics. The design of robust sampling programmes should be based on an underlying statistical distribution that is sufficiently flexible to capture variations in the spatial distribution of the target species. RESULTS Co...

BACKGROUND Given the increasing burden on colonoscopy capacity, it has been suggested that faecal immunochemical test (FIT) results could guide surveillance colonoscopy intervals. Against this background, we have evaluated the test accuracy of single and double FIT sampling to detect colorectal cancer (CRC) and/or advanced adenomas in an asymptomatic colonoscopy-controlled high-risk population....
