| 1 | Radiological diagnosis and staging of hilar cholangiocarcinoma显示文摘Hilar cholangiocarcinoma is a rare malignant tumor arising from the epithelium of the bile ducts.Surgery is still the only chance of potentially curative treatment in patients with perihilar cholangiocarcinoma.However,radical resection requires aggressive surgical strategies that should be tailored optimally according to the location,size and vascular invasion of the tumors.Accurate diagnosis and staging of these tumors is therefore critical for optimal treatment planning and for determining a prognosis.Multidetector computed tomography(MDCT),magnetic resonance imaging(MRI) and MR cholangiography are useful tools,both to diagnose and stage hilar cholangiocarcinoma.Modern imaging techniques allow accurate detection of the level of obstruction and the longitudinal and radial spread of the tumor.In addition,high-resolution MDCT and MR provide specific radiographic features to determine vascular involvement of anatomic structures,such as the hepatic artery or the portal vein,which are critical to decide the surgical strategy.Finally,radiological staging allows detection of patients with distant metastasis in the liver or peritoneum who will not benefit from a surgical approach. | Carlos Valls Sandra Ruiz Laura Martinez David Leiva | 2013 | World Journal of Gastrointestinal Oncology2013，5，7： | 21 |
| 2 | Archery Algorithm:A Novel Stochastic Optimization Algorithm for Solving Optimization Problems显示文摘Finding a suitable solution to an optimization problem designed in science is a major challenge.Therefore,these must be addressed utilizing proper approaches.Based on a random search space,optimization algorithms can find acceptable solutions to problems.Archery Algorithm(AA)is a new stochastic approach for addressing optimization problems that is discussed in this study.The fundamental idea of developing the suggested AA is to imitate the archer’s shooting behavior toward the target panel.The proposed algorithm updates the location of each member of the population in each dimension of the search space by a member randomly marked by the archer.The AA is mathematically described,and its capacity to solve optimization problems is evaluated on twenty-three distinct types of objective functions.Furthermore,the proposed algorithm’s performance is compared vs.eight approaches,including teaching-learning based optimization,marine predators algorithm,genetic algorithm,grey wolf optimization,particle swarm optimization,whale optimization algorithm,gravitational search algorithm,and tunicate swarm algorithm.According to the simulation findings,the AA has a good capacity to tackle optimization issues in both unimodal and multimodal scenarios,and it can give adequate quasi-optimal solutions to these problems.The analysis and comparison of competing algorithms’performance with the proposed algorithm demonstrates the superiority and competitiveness of the AA. | Fatemeh Ahmadi Zeidabadi Mohammad Dehghani Pavel Trojovsky Štěpán Hubálovsky Victor Leiva Gaurav Dhiman | 2022 | Computers, Materials & Continua2022，，7： | 2 |
