Pancreaticojejunostomy is the key procedure of pancreaticoduodenectomy. Our study introduced a new pancreaticojejunal (PJ) anastomosis named "papillary-like main pancreatic duct invaginated" pancreaticojejunostomy. Nighty-two patients underwent pancreaticojejunostomy with either conventional duct-to-mucosa pancreaticojejunostomy or the new "papillary-like(More)
In this paper, the hierarchical chart for open-end fund performance evaluation is obtained by using the analytic hierarchy process. Furthermore, by utilizing the fuzzy and grey comprehensive evaluation methods, a scoring model for the evaluation of open-end funds is established. A 3σ method-based comparison model is then constructed. Finally, an(More)
A new hybrid algorithm for image segmentation based on k-mean and particle swarm optimization algorithm is proposed in the paper. K-mean clustering algorithm is a local search algorithm because it is easily to be trapped in local optimum and is sensitive to initial value effectively. On the other hand, particle swarm optimization algorithm is a global(More)
