—In this paper, we utilize Chemical Reaction Optimization (CRO), a newly proposed metaheuristic for global optimization, to design Fuzzy Rule-Based Systems (FRBSs). CRO imitates the interactions of molecules in a chemical reaction. The molecular structure corresponds to a solution, and the potential energy is analogous to the objective function value.(More)
Amyloid β(Aβ) peptides are important components of plaques in Alzheimer's disease(AD). A decrease in the CSF concentration of Aβ40 and Aβ42 is a potential biomarker for incident AD. In contrast, studies on plasma Aβ40 and Aβ42 concentrations have yielded contradictory results. To explore the relationship between plasma Aβ40 and Aβ42 concentrations and AD in(More)
—Formalized analysis method is a technology that insures quality of software reliability. It can detect mistakes and flaws effectively in software design. Based on the research of model checking techniques for composition of web services, we establish an automatic test framework for web services composition of BPEL. Static test method is used and test cases(More)
BACKGROUND/AIMS Achalasia patients would feel exacerbated dysphagia, chest pain and regurgitation when they drink cold beverages or eat cold food. But these symptoms would relieve when they drink hot water. Reasons are unknown. METHODS Twelve achalasia patients (mean age, 34 ± 10 years; F:M, 3:9) who never had any invasive therapies were chosen from(More)
