1Modified binary particle swarm optimization显示文摘This paper presents a modified binary particle swarm optimization (BPSO) which adopts concepts of the genotype-phenotype rep-resentation and the mutation operator of genetic algorithms.Its main feature is that the BPSO can be treated as a continuous PSO.The proposed BPSO algorithm is tested on various benchmark functions, and its performance is compared with that of the original BPSO.Experimental results show that the modified BPSO outperforms the original BPSO algorithm.Sangwook Lee Sangmoon Soak Sanghoun Oh Witold Pedrycz Moongu Jeon 2008Progress in Natural Science:Materials International2008,18,9:11
2Single hepatocellular carcinoma ≤ 3 cm in left lateral segment:Liver resection or radiofrequency ablation?显示文摘AIM:To evaluate the long-term results of radiofrequency ablation(RFA)compared to left lateral sectionectomy(LLS)in patients with Child-Pugh class A disease for the treatment of single and small hepatocellular carcinoma(HCC)in the left lateral segments.METHODS:We retrospectively reviewed the data of133 patients with single HCC(≤3 cm)in their left lateral segments who underwent curative LLS(n=66)or RFA(n=67)between 2006 and 2010.RESULTS:The median follow-up period was 33.5mo in the LLS group and 29 mo in the RFA group(P=0.060).Most patients had hepatitis B virus-related HCC.The hospital stay was longer in the LLS group than in the RFA group(8 d vs 2 d,P<0.001).The 1-,2-,and 3-year disease-free survival and overall survival rates were 80.0%,68.2%,and 60.0%,and 95.4%,92.3%,and 92.3%,respectively,for the LLS group;and 80.8%,59.9%,and 39.6%,and 98.2%,92.0%,and 74.4%,respectively,for the RFA group.The disease-free survival curve and overall survival curve were higher in the LLS group than in the RFA group(P=0.012 and P=0.013,respectively).Increased PIVKA-Ⅱlevels and small tumor size were associated with HCC recurrence in multivariate analysis.CONCLUSION:Liver resection is suitable for single HCC≤3 cm in the left lateral segments.Jong Man Kim Tae Wook Kang Choon Hyuck David Kwon Jae-Won Joh Justin Sangwook Ko Jae Berm Park Hyunchul Rhim Joon Hyeok Lee Sung Joo Kim Seung Woon Paik 2014World Journal of Gastroenterology2014,20,14:4
3OPERATIONAL TROPICAL CYCLONE FORECAST VERIFICATION PRACTICE IN THE WESTERN NORTH PACIFIC REGION显示文摘This paper summarizes results of a survey of the operational status of tropical cyclone(TC) forecast verifi-cation in the western North Pacific region, covering the Members of the ESCAP/WMO Typhoon Committee, RSMC Tokyo-Typhoon Center, and JTWC. Results of the survey indicate that significant efforts have been focused on the verification of TC forecast guidance by operational forecast agencies in the region, either individually or through international cooperation. A variety of TC forecast verification products are available to the forecasters in either real time or in post-season through multiple means, with the main focus on the deterministic track and intensity forecasts. Only a few verification products are available for probabilistic forecasts. Verification of TC precipitation and high wind forecasts are also lacking sufficient attention in the region. It would be helpful in the future to focus more attention toward these aspects and incorporate methods that will provide a greater depth of information regarding the TC forecast performance.HUI YU SAI TICK CHAN BARBARA BROWN MASASHI KUNITSUGU EDWARD FUKADA SANGWOOK PARK WOOJEONG LEE YINGLONG XU PEOU PHALLA BOUNTEUMSYSOUPHANTHAVONG SAU WA CHANG CHE GAYAH ISMAIL RENITO BPACIENTE PATRICIA EE CHAMNONG KAEOCHADA HOA VO VAN 2012Tropical Cyclone Research and Review2012,1,3:3
