BACKGROUND AND AIMS Discrimination of gastric adenomas from adenocarcinomas by conventional endoscopy is difficult. Therefore, we evaluated the usefulness of magnifying endoscopy combined with narrow-band imaging for this differential diagnosis. METHODS Forty-nine consecutive gastric lesions were diagnosed as adenomas by conventional endoscopy with forceps biopsy and finally resected by endos...

The operation planning problem encounters several uncertainties in terms of the power system’s parameters such as load, operating reserve and wind power generation. The modeling of those uncertainties is an important issue in power system operation. The system operators can implement different approaches to manage these uncertainties such as stochastic and fuzzy methods. In this paper, new ...
