The automated computation of tree-level and next-to-leading order differential cross sections, and their matching to parton shower simulations [PDF]
Journal of High Energy Physics, 2014 A bstractWe discuss the theoretical bases that underpin the automation of the computations of tree-level and next-to-leading order cross sections, of their matching to parton shower simulations, and of the merging of matched samples that differ by light ...

Editor's note: This article is one in a series on clinical research by nurses. The series is designed to give nurses the knowledge and skills they need to participate in research, step by step. Each column will present the concepts that underpin evidence-based practice—from research design to data interpretation.

Cross-sectional echocardiography
British Medical Bulletin, 1989Cross-sectional echocardiography has become an essential part of the investigation of infants and children with heart disease. Frequently, it provides a precise diagnosis. In many instances, particularly in neonates and infants, surgery can be undertaken without the need to proceed to cardiac catheterisation.

Across-sectional study is an observational study in which the exposure and the outcome are determined at the same time point for each study participant. Cross-sectional studies comprise the simplest individual-level observational study design and are usually relatively inexpensive and easy to conduct compared with case-control or cohort studies.
