More than 90% of colorectal cancer is gradually transformed from polyps. In clinical practice, precise polyp segmentation provides important information in the early detection cancer. Therefore, automatic techniques are great importance for both patients and doctors. Most existing methods based on U-shape structure use element-wise addition or concatenation to fuse different level features prog...

The nonequilibrium Ising model on a restricted scale-free network has been studied with one- and two-spin flip competing dynamics employing Monte Carlo simulations. present in the system can be defined by probability q which one-spin process simulate contact heat bath at given temperature T, (1−q) mimics subjected to an external flux of energy into it. is described power-law degree distribution...

in this research prediction methods of artificial neural network and chaos theory are employed to predict daily, weekly and monthly runoff. for this, runoff series data observed at pole-kohneh located in the qareh-soo river. the nonlinear predictions of chaos are found to be in close agreement with the observed runoff, with high correlation coefficient for daily and weekly time scales. predicte...
