Based on the boarding and alighting ridership data collected at 236 subway stations in Beijing, a cluster analysis method is used to divide them into nine categories. The two-factor variance test shows the feasibility of the proposed category and indicates that there are significant differences among different category of subway stations. The characteristics of surrounding population, employment,...
Our objectives were to study risk factors and post-operative outcomes associated with excessive post-operative bleeding in pediatric cardiac surgeries performed using cardiopulmonary bypass (CPB) support. A retrospective observational study was undertaken, and all consecutive pediatric heart surgeries over 1 year period were studied. Excessive post-operative bleeding was defined as 10 ml/kg/h...
Plant biology is becoming a data-driven science. High-throughput technologies generate data quickly from molecular to ecosystem levels. Statistical and computational approaches enable describing and interpreting data quantitatively. We highlight the purpose, common problems, and general principles in data analysis. We use RNA sequencing (RNAseq) analysis to illustrate the rationale behind some of...
