Knowledge acquisition is a diicult, error-prone, and time-consuming task. The task of automatically improving an existing knowledge base using learning methods is addressed by the class of systems performing theory reenement. This paper presents a system, Forte (First-Order Revision of Theories from Examples), which reenes rst-order Horn-clause theories by integrating a variety of diierent revi...

OBJECTIVE We sought to develop a novel biochemical assay and algorithm for the prenatal evaluation of risk for fetal trisomy 21 (T21) and trisomy 18 (T18) using cell-free DNA obtained from maternal blood. STUDY DESIGN We assayed cell-free DNA from a training set and a blinded validation set of pregnant women, comprising 250 disomy, 72 T21, and 16 T18 pregnancies. We used digital analysis of s...

Cotazym-S-Forte, a new pancreatic supplement containing 10,000 BP units of lipase activity per capsule, was compared with a standard dose pancreatin supplement (Pancrease) with 5000 BP units lipase activity in a randomised crossover trial. The number of capsules of Cotazym-S-Forte administered was half the usual number of Pancrease capsules and was associated with the same degree of fat absorpt...

Red yeast rice (RYR) can reduce cholesterol through its active component, lovastatin. This study was to investigate the pharmacokinetic properties of lovastatin in RYR products and potential RYR-drug interactions. Extracts of three registered RYR products (LipoCol Forte, Cholestin, and Xuezhikang) were more effective than pure lovastatin in inhibiting the activities of cytochrome P450 enzymes a...

A study is reported investigating the relationship between modality (major/minor) and dynamics (piano/forte) on four affects – as evident in the content of musical lyrics. Forty solo vocal works were sampled: 10 in the major mode with a loud (forte) dynamic level, 10 in the major mode with a quiet (piano) dynamic level, 10 in the minor mode with a loud dynamic level, and 10 in the minor mode wi...
