We have developed a new 3D multi-physics multi-material code, ALE-AMR, which combines Arbitrary Lagrangian Eulerian (ALE) hydrodynamics with Adaptive Mesh Refinement (AMR) to connect the continuum to the microstructural regimes. The code is unique in its ability to model hot radiating plasmas and cold fragmenting solids. New numerical techniques were developed for many of the physics packages to work efficiently on a dynamically moving and adapting mesh. We use interface reconstruction based on volume fractions of the material components within mixed zones and reconstruct interfaces as needed. This interface reconstruction model is also used for void coalescence and fragmentation. A flexible strength/failure framework allows for pluggable material models, which may require material history arrays to determine the level of accumulated damage or the evolving yield stress in J2 plasticity models. For some applications laser rays are propagating through a virtual composite mesh consisting of the finest resolution representation of the modeled space. A new 2nd order accurate diffusion solver has been implemented for the thermal conduction and radiation transport packages. One application area is the modeling of laser/target effects including debris/shrapnel generation. Other application areas include warm dense matter, EUV lithography, and material wall interactions for fusion devices. 展开更多

A review of the literature suggests that errors in death certification are common. We reviewed the published literature to clarify what is known and what remains to be learned before evidence-based changes in medical education can be recommended. We searched the National Library of Medicine’s PubMed database for articles that addressed death certificate accuracy and identified 159 articles of interest published from 1996 to 2010. Among these 159 articles, we found 83 that were relevant to our goals and objectives. Cause of death certification has been shown to be problematic and several interventions have been shown to improve its accuracy, especially if the intervention is interactive. However these studies have focused on short term gains rather than on long term retention and performance, leaving a significant data gap. We suggest a study design that could address this data gap. 展开更多
