The prostate gland contains a higher concentration of zinc than any soft tissue in the human body previously investigated. In an extensive series of analyses Eggleton found the highest concentration in liver (245 μgm. Zn per gm. dry weight), whereas the mean zinc content of all our specimens of human prostate was 682 ± 70 μgm. per gm. dry weight. Carcinomatous prostates contained much less zinc than normal glands, and the amount of zinc in any given prostate was directly related to the proportion of alveolar tissue present.
Gaining higher level evolutionary information about large software systems is a key in validating past and adjusting future development processes. In this paper, we analyze the proximity of software features based on modifi-
Observing the evolution of very large software systems needs the analysis of large complex data models and visualization of condensed views on the system. For visualization software metrics have been used to compute such condensed views. However, current techniques concentrate on visualizing data of one particular release providing only insufficient support for visualizing data of several releases.In this paper we present the RelVis visualization approach that concentrates on providing integrated condensed graphical views on source code and release history data of up to n releases. Measures of metrics of source code entities and relationships are composed in Kiviat diagrams as annual rings. Diagrams highlight the good and bad times of an entity and facilitate the identification of entities and relationships with critical trends. They represent potential refactoring candidates that should be addressed first before further evolving the system. The paper provides needed background information and evaluation of the approach with a large open source software project.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
