We use WZ-summation methods to compute recurrences for the Ising-class integrals Cn,k. In this context, we describe an algorithmic approach to obtain homogeneous and inhomogeneous recurrences for a general class of multiple contour integrals of Barnes’ type.

A total of70 children aged 6 to 15 years with rheumatic fever and completed in-hospital data were reviewed from 19XX to 1993. In 5X.6% of patients this was the first attack of disease, while in 41.4'10 the episode represented a recurrence. Noncompliance of antimicrobial prophylaxis was noted in all of the subjects with recurrences. 61.4% of cases gave a previous history of sore throat, and ...
