Bionimbus: a cloud for managing, analyzing and sharing large genomics datasets.

Background: As large genomics and phenotypic datasets are becoming more common, it is increasingly difficult for most researchers to access, manage, and analyze them. One possible approach is to provide the research community with several petabyte-scale cloud-based computing platforms containing these data, along with tools and resources to analyze it.

Methods: Bionimbus is an open source cloud-computing platform that is based primarily upon OpenStack, which manages on-demand virtual machines that provide the required computational resources, and GlusterFS, which is a high-performance clustered file system.

Cancer incidence in Kentucky, Pennsylvania, and West Virginia: disparities in Appalachia.

Context: Composed of all or a portion of 13 states, Appalachia is a heterogeneous, economically disadvantaged region of the eastern United States. While mortality from cancer in Appalachia has previously been reported to be elevated, rates of cancer incidence in Appalachia remain unreported.

Purpose: To estimate Appalachian cancer incidence by stage and site and to determine if incidence was greater than that in the United States.
