A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...

Purpose The purpose of this study was to investigate the effects prosthetic interventions in patients with Kennedy Class ? (unilateral missing posterior teeth) on mastication predominance.Methods subjects comprised II and healthy dentate volunteers (HD group). were asked freely chew test foods (chewing gum, beef jerky, peanuts). Electromyographic activity bilateral masseter muscles recorded twi...

MPI accomplishes portable, standardized message-passing between processes by exposing a standard API that hides the implementation of the underlying mechanism for message passing. Until now, checkpointing an MPI program required knowledge of these underlying mechanisms. Through the addition of a proxy, we demonstrate that MPI programs can be checkpointed and restarted regardless of the MPI impl...

We present a simple library which equips MPI implementations with truly asynchronous non-blocking point-to-point operations, and which is independent of the underlying communication infrastructure. It utilizes the MPI profiling interface (PMPI) and the MPI_THREAD_MULTIPLE thread compatibility level, and works with current versions of Intel MPI, Open MPI, MPICH2, MVAPICH2, Cray MPI, and IBM MPI....

A new software package BC-MPI which allows an MPI application to run on several clusters with various MPI implementations is presented. It uses vendor MPI implementations for communication inside clusters and exploits the multithreaded MPI THREAD MULTIPLE mode for handling inter-cluster communication in additional threads of the MPI application. Furthermore, a BC-MPI application can be automati...
