Seventy-five years ago, Yates (1934) presented an article introducing his continuity correction to the χ test for independence in contingency tables. The paper also was one of the first introductions to Fisher’s exact test. We discuss the historical importance of Yates and his 1934 paper. The development of the exact test and continuity correction are studied in some detail. Subsequent disputes...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...

planned pregnancy among these countries is strikingly reflected in the disparity in abortion rates. The overall U. S. abortion rate (25.9 abortions per 1,000 women aged 15–44) is 1.7 times that of Canada (15.3 per 1,000) and more than four times that of the Netherlands (6.0 per 1,000).5 Differences in pregnancy rates, however, are not so marked. Again, the United States reports the highest rate...
The neuromuscular blocking agent cisatracurium is frequently used adjunctively in anesthesia to facilitate endotracheal intubation and to provide muscle relaxation during surgery. We aimed to determine the pharmacokinetics (PK)/pharmacodynamics (PD) of cisatracurium in patients with congenital heart defects (CHDs), such as ventricular septal defects and atrial septal defects, and to assess the ...
