AIMS To evaluate the diagnostic accuracy of a combined non-invasive assessment of coronary artery disease with coronary CT angiography (CTA) and myocardial perfusion imaging (MPI) for the detection of flow-limiting coronary stenoses and its potential as a gatekeeper for invasive examination and treatment. METHODS AND RESULTS In 78 patients (mean age 65 +/- 9 years) referred for coronary angio...

Background—ACC/AHA Appropriate Use Criteria recommend performing stress MPI for intermediate to high-risk patients presenting with syncope, but not for low-risk patients. However, there are limited data to support these recommendations. We investigated the yield of stress MPI for the evaluation of syncope in patients at risk but without known CAD Methods and Results—From the Cleveland Clinic IR...

Communication library is a substantially important part for the development of the parallel applications on PC clusters. MPI is currently the most important messaging passing standard being used worldwide. Although powerful, MPI is very complex and require a certain amount of effort to learn. In fact, only a basic set of MPI functions is enough to develop a large class of parallel applications....

BACKGROUND The Multidimensional Pain Inventory (MPI) is a reliable and valid self-report instrument that measures the impact of pain on an individual's life, quality of social support and general activity. Criticism of the MPI has focused on this instrument's internal structure and the stability of its classification taxonomy. OBJECTIVES To determine whether empirical summary scales could be ...

BACKGROUND The myocardial performance index (MPI) first described by Chuwa Tei in 1995 is a relatively new echocardiographic variable used for assessment of overall cardiac function. Previous studies have demonstrated the MPI to be a sum representation of both left ventricular systolic and diastolic function with prognostic value in patients with coronary artery disease as well as symptomatic h...

Initial versions of MPI were designed to work efficiently on multi-processors which had very little job control and thus static process models. Subsequently forcing them to support a dynamic process model suitable for use on clusters or distributed systems would have reduced their performance. As current HPC collaborative applications increase in size and distribution the potential levels of no...

Manufacturing process innovation (MPI), an organization-wide effort involving radical redesign of manufacturing related processes and systems to achieve dramatic improvements in critical manufacturing performance measures, encompasses various kinds of activities. Some MPI initiatives focus on technological innovation and others may intend to change work processes and ganizations adopt new techn...

Introduction: A Master Patient Index(MPI) is a centralized index of all patients in a health care system. This index is composed of a unique identifier for each patient link to his/her demographic data and clinical encounters. A MPI is essential to ensure data interoperability in different health care institution. The Health ministry of Sri Lanka planning to develop MPI for the country. This pr...

There are several existing concepts and solutions that are intended for coupling several parallel computers in means of running a single MPI application on top of them. PACX–MPI [1] is one of them that relies on existing MPI libraries on the respective machines. This paper discusses several facts and aspects for using PACX–MPI in an Cluster–of–Clusters (CoC) environment.

The MPI remote-memory access (RMA) operations provide a different programming model from the regular MPI-1 point-to-point operations. This model is particularly appropriate for cases where there are multiple communication events for each synchronization and where the target memory locations are known by the source processes. In this paper, we describe a benchmark designed to illustrate the perf...
