A 46-year-old man was admitted with epigastric pain, weight loss, and hypoalbuminemia. He had no history of gastric surgery. A gastroscopy revealed giant polypoid gastric folds within the gastric body and fundus (●" Fig.1) and several polyps with central erosion in the gastric antrum (●" Fig.2). Biopsies of the gastric body and antral lesions revealed chronic gastritis. Endoscopic ultrasound sh...

AbsractGastritis cystic polyposa is a rare and peculiar polypoid lesion arising at a gastroenterostomysite, and almost always on the gastric side. It is characterized by elongationof the gastric foveolae along with hyperplasia and cystic dilatation of the gastricglands extending into the submucosal layer.

This paper proposes a new method based on the cultural algorithm to solve graph coloring problem (GCP). Graph coloring problem involves finding the minimum number of colors for coloring the graph vertices such that adjacent vertices have distinct colors. In this paper various components of cultural algorithm have been implemented to solve GCP with a self adaptive behavior in an efficient manner...

The paper investigates the influence of versatile crossover and mutation operators on the efficiency of evolutionary search in solving two important classes of hard optimization problems. Chromosome representations of set partitions and permutations defined in the paper are not problem–oriented and are described together with their versatile variation operators. The proposed representations are...
