Arnold transformation is applied widely in digital image encryption because of its periodicity. But if its periodicity is used in the course of image decryption, it will waste lots of time. So this paper offers a new anti-Arnold transformation algorithm. The algorithm gets anti-Arnold transformation by solving equation groups. The application of Arnold(More)
Hepatic inflow occlusion during the liver surgery may result in a transient ischemia period followed by reperfusion, and may initiate liver injury and lead to postoperative liver dysfunction. Especially in cirrhotic patients, the tolerance time of ischemia is much shorter and the outcome would be worse. Recently, clinical trials had proved that volatile(More)
