Background—This study investigated whether the extent of perfusion defect determined by intravenous myocardial contrast echocardiography (MCE) in patients with acute myocardial infarction (AMI) treated by primary percutaneous transluminal coronary angioplasty (PTCA) relates to coronary flow reserve (CRF) for assessment of myocardial reperfusion and is predictive for left ventricular recovery. M...

Myocardial Contrast Echocardiography (MCE) is a recent technique that allows to measure regional perfusion in the cardiac wall. Segmentation of MCE sequences would allow simultaneous evaluation of perfusion and wall motion. This paper deals with the application of partial differential equations (PDE) for tracking the endocardial wall. We use a variational optical flow method which we solve nume...

BACKGROUND Although assessment of myocardial perfusion by myocardial contrast echocardiography (MCE) is feasible, its incremental benefit to stress echocardiography is not well defined. We examined whether the addition of MCE to combined dipyridamole-exercise echocardiography (DExE) provides incremental benefit for evaluation of coronary artery disease (CAD). METHODS AND RESULTS MCE was combi...

The study illustrates the use of Geographic Information System (GIS) tools and numerical Multi-Criteria Evaluation (MCE) techniques for selection of suitable sites for urban development of a hill town. This study was conducted to identify suitable sites for urban development of a hill town, Nahan using GIS-based multi-criteria evaluation of slope, road proximity, land use, land values, soil and...

Tourism, one of the expeditiously growing and most important sectors, contributes to national economy by increasing employment foreign exchange income. As in many countries, place tourism country's is very T?rkiye (formerly known as Turkey). sources that have contributed significantly for years, it has played a locomotive role its development. trying increase share international revenues with i...

In this study, the suitable areas for soybean in China were presented by GIS-based Multi-Criteria Evaluation (MCE) approach. We collected datas of environmental conditions and soybean growth associated factors, then, by the GIS technology we established spatial database of regional weather, topography, and soil conditions. Using the Spatial Analyst, the Spatial Interpolation, the Reclassificati...

The evaluation and selection of recommender systems is a difficult decision making process. This difficulty is partially due to the large diversity of published evaluation criteria in addition to lack of standardized methods of evaluation. As such, a systematic methodology is needed that explicitly considers multiple, possibly conflicting metrics and assists decision makers to evaluate and find...

Microchip electrophoresis (MCE) has been recognized as an important separation technique on the research field of micro total analytical systems (μ-TAS) since the first publication on MCE was reported by Manz et al. in 1992 [1]. In MCE, there are several advantages, e.g., high speed analysis in seconds, small amount of sample, high separation efficiency, and high-throughput analysis by using mi...

higher education plays a very vital role in developing human resources as well as economic ones in every country. in so doing, the act of evaluation would help the decision makers as well as managers to spot the weaknesses to use the required provisions to work more effectively. the present study with a different approach toward the designing a comprehensive evaluation expert system using fuzzy...
