Evaluation of Metal Artifact Reduction software in Computed Tomography
Introduction: The image quality of computed tomography (CT) can be seriously lowered by metal implants of patients. These implants are known to exert a significant impact on diagnostic accuracy due to artifacts. The current study aimed to assess the usefulness of Metal Artifact Reduction (MAR) software in the reduction of metal artifacts, in comparison to iterative rec...
متن کاملUnderstanding software artifact provenance
In a well designed software system, units of related functionality are organized into modules and classes, which are in turn arranged into inheritance trees, package hierarchies, components, libraries, frameworks, and services. The trade-offs between simplicity versus flexibility and power are carefully considered, and interfaces are designed that expose the key functional properties of a compo...
متن کاملLate Mitochondrial Origin Is an Artifact
The origin of mitochondria was a crucial event in eukaryote evolution. A recent report claimed to provide evidence, based on branch length variation in phylogenetic trees, that the mitochondrion came late in eukaryotic evolution. Here, we reinvestigate their claim with a reanalysis of the published data. We show that the analyses underpinning a late mitochondrial origin suffer from multiple fat...
متن کاملThe Earth is not yet an artifact
n the previous article in this issue [1], Brad Allenby argues for a more active style of planetary management. He notes, " the biosphere itself, at levels from the genetic to the landscape , is increasingly a human product. " While the earth is undoubtedly being transformed by human action [2]-[4], the implications of the transformation for environmental management are in dispute. Allenby sugge...
متن کاملThe Handicap Principle Is an Artifact
The handicap principle is one of the most influential ideas in evolutionary biology. It asserts that when there is conflict of interest in a signaling interaction signals must be costly in order to be reliable. While in evolutionary biology it is a common practice to distinguish between indexes and fakable signals, we argue this dichotomy is an artifact of existing popular signaling models. Onc...
