How accurate are 3 risk prediction models in US women?
Cardiovascular disease (CVD) is the leading cause of death for US women, and nearly two thirds who died suddenly of CVD had no previous symptoms.1 Therefore, it is of great importance to identify “at-risk” women early, so that effective primary prevention strategies can be instituted. A universal recommendation of prevention guidelines is that all asymptomatic women should undergo a global risk...

متن کاملAre discrete models more accurate?
Newton’s second law describes the motion of the center of mass of most objects that we encounter in everyday life, including the complex motion of a spoon when we eat, the acceleration of a car, and even the trajectories of planets and stars. Only if objects move extremely fast, do we need to replace Newton’s second law with Einstein’s theory of relativity, and only if objects are extremely sma...
متن کاملHow accurate are accurate force-fields for B-DNA?
Last generation of force-fields are raising expectations on the quality of molecular dynamics (MD) simulations of DNA, as well as to the belief that theoretical models can substitute experimental ones in several cases. However these claims are based on limited benchmarks, where MD simulations have shown the ability to reproduce already existing 'experimental models', which in turn, have an uncl...
