Recent changes to the pattern matching algorithm used by CLIPS have dramatically improved performance on the classic waltz and manners benchmarks, which are frequently cited as measures of performance for rule-based systems. While the usefulness of these benchmarks is disputed, particularly for product comparisons, many believe that waltz and manners exhibit characteristics of some ‘real world’...

The endocardium, the endothelial lining of the heart, plays complex and critical roles in heart development, particularly in the formation of the cardiac valves and septa, the division of the truncus arteriosus into the aortic and pulmonary trunks, the development of Purkinje fibers that form the cardiac conduction system, and the formation of trabecular myocardium. Current data suggest that th...

Throughout the history of computational linguistics the rule-based and the statistics-based approaches appeared as competing rather than complementary threads of research. Even today, many view the success of the Xerox rule-based taggers as a threat to the more statistically oriented taggers, just as a few years ago the IBM statistical approach was viewed as a threat to rule-based systems of ma...

The transcriptional regulation of cardiovascular development requires precise spatiotemporal control of gene expression, and heterozygous mutations of transcription factors have frequently been implicated in human cardiovascular malformations. A novel mechanism involving post-transcriptional regulation by small, noncoding microRNAs (miRNAs) has emerged as a central regulator of many cardiogenic...

A novel RFX6 homozygous missense mutation was identified in an infant with Mitchell-Riley syndrome. The most common features of Mitchell-Riley syndrome were present, including severe neonatal diabetes associated with annular pancreas, intestinal malrotation, gallbladder agenesis, cholestatic disease, chronic diarrhea, and severe intrauterine growth restriction. Perijejunal tissue similar to pan...

In this paper, we collect radio and X-ray observations for most Fanaroff-Riley I (FRI) radio galaxies in the Zirbel-Baum radio galaxy sample, and investigate the distribution of the radio-to-X-ray effective spectral index, αrx, to test the unified scheme of BL Lac objects and FRI radio galaxies. It is found that the range of αrx for FRI radio galaxies is almost the same as that for BL Lac objec...

The legacy of Matilda White Riley to the study of aging encompasses multiple disciplines and extends to multiple domains within these disciplines. Although her greatest intellectual legacy is in sociology, she presented a compelling vision of the need for other disciplines to consider the role of social forces in shaping both aging as an individual, lifelong process and age as a feature of cult...
