In the paper, we propose various approaches for tool integration based on modeltransformations over the Eclipse Modeling Framework (EMF). EMF is a key technology for toolintegration, which provides a framework for developing domain-specific modeling languagesby automatically generating Java code for model manipulation. Model transformations can becaptured by graph transformation...

Model transformation is one of the key activities in model-driven software development. An increasingly popular technology to define modeling languages is provided by the Eclipse Modeling Framework (EMF). Several EMF model transformation approaches have been developed, focusing on different transformation aspects. To validate model transformations wrt. functional behavior and correctness, a for...

PURPOSE The purpose of this study is to investigate the mechanism of cellular proliferation of electromagnetic field (EMF) on human intervertebral disc (IVD) cells. MATERIALS AND METHODS Human IVD cells were cultured three-dimensionally in alginate beads. EMF was exposed to IVD cells with 650 Ω, 1.8 millitesla magnetic flux density, 60 Hz sinusoidal wave. Cultures were divided into a control ...

The spores of ectomycorrhizal fungi (EMF) play critical roles in the population and community development of EMF. Here, the germination and infectivity of EMF spores are examined with reference to the ecological traits of the EMF species. Spores were collected from 12 EMF species, whose successional patterns have been studied in the volcanic desert on Mount Fuji, Japan. Spore germination experi...

Zinc as an essential trace element was reported to be involved in regulation of the growth and aging of cells. In this study, rat adipose-derived mesenchymal stem cells were exposed to extremely low frequency electromagnetic field (ELF-EMF) of 50 Hz and 20 mT to evaluate whether exposure to ELF-EMF in the presence of zinc sulfate (ZnSO4) affects the telomerase reverse transcriptase (TERT) gene ...

We point out that the central theme in the paper by Wang, Xiong, and Wang @Phys. Rev. B 61, R5090 ~2000!# is the inseparability of electron degrees of freedom and those of electromagnetic field ~EMF!. The dephasing of conduction electrons due to zero-point fluctuation ~ZPF! of EMF is because experiments probe electron degrees of freedom only. The treatment of ZPF of EMF in the above paper is ov...

This paper describes a model transformation from the Business Process Modeling Notation (BPMN) to the Business Process Execution Language for Web Services (BPEL4WS, or BPEL for short). We give the meta-models for both source and target language as EMF models and define EMF model transformation rules using our recently developed tool EMF Tiger, an Eclipse plug-in supporting modeling and executio...

cardiomyopathy characterized by endocardial fibrotic thickening that usually affects the apex of one or both ventricles. EMF has been reported in tropical and subtropical regions of Africa as well as in India, Brazil, Columbia, and Sri Lanka. EMF is uncommon in the United States; however, this cardiomyopathy has been reported in white patients, even in the absence of prior residence in tropical...

Epidemiologic and experimental research on the potential carcinogenic effects of extremely low frequency electromagnetic fields (EMF) has now been conducted for over two decades. Cancer epidemiology studies in relation to EMF have focused primarily on brain cancer and leukemia, both from residential sources of exposure in children and adults and from occupational exposure in adult men. Because ...

Plant biodiversity is often correlated with ecosystem functioning in terrestrial ecosystems. However, we know little about the relative and combined effects of above- and belowground biodiversity on multiple ecosystem functions (for example, ecosystem multifunctionality, EMF) or how climate might mediate those relationships. Here we tease apart the effects of biotic and abiotic factors, both ab...
