BACKGROUND Although many patient, physician, and payment predictors of adherence have been described, knowledge of their relative strength and overall ability to explain adherence is limited. OBJECTIVES To measure the contributions of patient, physician, and payment predictors in explaining adherence to statins. RESEARCH DESIGN Retrospective cohort(More)
As part of its effort to periodically investigate various new promising concepts and techniques, the Digital Equipment Corporation has sponsored a research project whose purpose it was to effect a limited implementation of a protective operating system framework, based on the <underline>kernel/domain</underline> architecture which has increasingly been(More)

An issue-oriented architecture designed for high performance is described. It uses features, such as simple instruction formats, large number of registers, and load/store architecture, found in some reduced-instruction-set-computer architectures. It also includes features, such as out-of-order completion, imprecise exceptions, and vector processing, found(More)
An introduction to, and an overview of, a real-time, multiprogrammed operating system nucleus is presented. Taking a tutorial slant, the paper presents both the hardware and software interrupt mechanisms utilized in support of the nucleus. Also covered are the management of system resources (memory and I/O), and the operation and control of the system. Thus(More)
