Abstract Background: The Pediatric Acute Care Cardiology Collaborative (PAC3) was estab‐ lished in 2014 to improve the quality, value, and experience of hospital‐based cardiac acute care outside of the intensive care unit. An initial PAC3 project was a compre‐ hensive survey to understand unit structure, practices, and resource utilization across the collaborative. This report aims to describe the previously unknown degree of practice variation across member institutions.
Methods: A 126‐stem question survey was developed with a total of 412 possible response fields across nine domains including demographics, staffing, available re‐ sources and therapies, and standard care practices. Five supplemental questions ad‐… More >

Abstract Due to more complex and severe design, more effective and faster finite element analyses are demanded. One of the most effective analysis ways is the combination of adaptive analysis and multigrid iterative solver, because an adaptive analysis requires several meshes with different node densities and multigrid solver utilizes such meshes to accelerate its computation. However, convergence of multigrid solver is largely affected by initial shape of each element. An effective mesh improvement method is proposed here. It is the combination of mesh coarsening and refinement. A good mesh can be obtained by the method to be applied to an initial… More >
