2Optical vortices 30 years on:OAM manipulation from topological charge to multiple singularities显示文摘Thirty years ago,Coullet et al.proposed that a special optical field exists in laser cavities bearing some analogy with the superfluid vortex.Since then,optical vortices have been widely studied,inspired by the hydrodynamics sharing similar mathematics.Akin to a fluid vortex with a central flow singularity,an optical vortex beam has a phase singularity with a certain topological charge,giving rise to a hollow intensity distribution.Such a beam with helical phase fronts and orbital angular momentum reveals a subtle connection between macroscopic physical optics and microscopic quantum optics.These amazing properties provide a new understanding of a wide range of optical and physical phenomena,including twisting photons,spin–orbital interactions,Bose-Einstein condensates,etc.,while the associated technologies for manipulating optical vortices have become increasingly tunable and flexible.Hitherto,owing to these salient properties and optical manipulation technologies,tunable vortex beams have engendered tremendous advanced applications such as optical tweezers,high-order quantum entanglement,and nonlinear optics.This article reviews the recent progress in tunable vortex technologies along with their advanced applications.Yijie Shen Xuejiao Wang Zhenwei Xie Changjun Min Xing Fu Qiang Liu Mali Gong Xiaocong Yuan 2019Light(Science & Applications)2019,8,1:77
3Prevalence of Atrial Fibrillation in China and Its Risk Factors显示文摘Objective To study the prevalence of atrial fibrillation(AF)and the relation with its risk factors in China.Methods A total of 19 363 participants(8635 males and 10 728 females) aged ≥35 years in geographically dispersed urban and rural regions of China were included in this cross-sectional survey.All participants received questionnaire,physical and blood examination.Echocardiography were performed for AF patients found in the survey.Results Of the 19 363 participants,199 were diagnosed with AF.The estimated age-standardized prevalence of AF was 0.78% in men and 0.76% in women.The prevalence of AF in participants aged <60 years was 0.41% in men and 0.43% in women,and was 1.83% in both men and women aged ≥60 years.About 19.0% of males and 30.9% of females with AF were diagnosed with valve disease.Age-and sex-adjusted multivariable logistic regression analysis revealed that myocardial infarction,left ventricular hypertrophy(LVH),obesity,and alcohol consumption were associated with a increased risk of AF(P<0.05).Conclusion The age standardized prevalence of AF is 0.77% in the participants enrolled in the present study.The number of AF cases aged ≥35 years is 5.26 million according to 2010 Chinese Census.Most risk factors for AF,identified mainly in Western countries,are also detected in China.LI Ying WU Yang Feng CHEN Ke Ping LI Xian ZHANG Xing XIE Gao Qiang WANG Fang Zheng ZHANG Shu 2013Biomedical and Environmental Sciences2013,26,9:48
4Hybrid artificial bee colony algorithm with variable neighborhood search and memory mechanism显示文摘Artificial bee colony(ABC) is one of the most popular swarm intelligence optimization algorithms which have been widely used in numerical optimization and engineering applications. However, there are still deficiencies in ABC regarding its local search ability and global search efficiency. Aiming at these deficiencies,an ABC variant named hybrid ABC(HABC) algorithm is proposed.Firstly, the variable neighborhood search factor is added to the solution search equation, which can enhance the local search ability and increase the population diversity. Secondly, inspired by the neuroscience investigation of real honeybees, the memory mechanism is put forward, which assumes the artificial bees can remember their past successful experiences and further guide the subsequent foraging behavior. The proposed memory mechanism is used to improve the global search efficiency. Finally, the results of comparison on a set of ten benchmark functions demonstrate the superiority of HABC.FAN Chengli FU Qiang LONG Guangzheng XING Qinghua 2018Journal of Systems Engineering and Electronics2018,29,2:49

12Role of Ni(NO_3)_2 in the preparation of a magnetic coal-based activated carbon显示文摘The role of Ni(NO3)2 in the preparation of a magnetic activated carbon is reported in this paper.Magnetic coal-based activated carbons(MCAC) were prepared from Taixi anthracite with low ash content in the presence of Ni(NO3)2.The MCAC materials were characterized by a vibrating sample magnetometer(VSM),X-ray diffraction(XRD),a scanning electric microscope(SEM),and by N2 adsorption.The cylindrical precursors and derived char were also subjected to thermogravimetric analysis to compare their behavior of weight losses during carbonization.The results show that MCAC has a larger surface area(1074 m2/g) and a higher pore volume(0.5792 cm3/g) with enhanced mesopore ratio(by about 10%).It also has a high saturation magnetization(1.6749 emu/g) and low coercivity(43.26 Oe),which allows the material to be magnetically separated.The MCAC is easily magnetized because the nickel salt is converted into Ni during carbonization and activation.Metallic Ni has a strong magnetism on account of electrostatic interaction.Added Ni(NO3)2 catalyzes the carbonization and activation process by accelerating burn off of the carbon,which contributes to the development of mesopores and macropores in the activated carbon.ZhangJun Xie Qiang Liu Juan Yang Mingshun Yao Xing 2011Mining Science and Technology2011,21,4:17

17Clinical practice guidelines on liver transplantation for hepatocellular carcinoma in China(2018 edition)显示文摘Introduction Over 300000 people in China die each year of hepatocellular carcinoma(HCC),which accounts for approximately half of HCCrelated deaths worldwide.Liver transplantation(LT)is generally recognized as one of the most effective therapeutic approaches for end-stage liver diseases.Since the beginning of the second LT boom in the 1990s,LT in China has been developed rapidly with professional and large-scale trends,and it is approaching or has reached the level of developed countries in terms of quantity and quality.According to the China Liver Transplant Registry,the number of transplants for HCC accounted for 36.8%of the total number of LT cases during the past 5 years in the mainland of China.In order to develop an effective,safe and standardized protocol to guide the national LT practice,the clinical guidelines of LT for HCC was launched in 2014 by multidisciplinary experts from Chinese Society of Organ Transplantation,Chinese Medical Association and Chinese Association of Organ Transplantation,Chinese Medical Doctor Association.Recently,there have been new clinical and scientific advances in the field of LT and to keep abreast of these achievements,the original clinical practice guidelines need to be updated.Xiao Xu Jun Chen Qiang Wei Zhi-Kun Liu a Zhe Yang Ming Zhang Guo-Ying Wang Jie Gao Zhao-Xu Yang Wen-Yuan Guo Tong-Hai Xing Zhou Shao Qin-Fen Xie Shu-Sen Zheng 2019Hepatobiliary & Pancreatic Diseases International2019,18,4:14
18A WD-GA-LSSVM model for rainfall-triggered landslide displacement prediction显示文摘This paper proposes a WD-GA-LSSVM model for predicting the displacement of a deepseated landslide triggered by seasonal rainfall,in which wavelet denoising(WD)is used in displacement time series of landslide to eliminate the GPS observation noise in the original data,and genetic algorithm(GA)is applied to obtain optimal parameters of least squares support vector machines(LSSVM)model.The model is first trained and then evaluated by using data from a gentle dipping(~2°-5°)landslide triggered by seasonal rainfall in the southwest of China.Performance comparisons of WD-GA-LSSVM model with Back Propagation Neural Network(BPNN)model and LSSVM are presented,individually.The results indicate that the adoption of WD-GA-LSSVM model significantly improves the robustness and accuracy of the displacement prediction and it provides a powerful technique for predicting the displacement of a rainfall-triggered landslide.ZHU Xing MA Shu-qi XU Qiang LIU Wen-de 2018Journal of Mountain Science2018,15,1:10
19Optimization of succinic acid fermentation with Actinobacillus succinogenes by response surface methodology(RSM)显示文摘Succinic acid is considered as an important platform chemical.Succinic acid fermentation with Actinobacillus succinogenes strain BE-1 was optimized by central composite design(CCD)using a response surface methodology(RSM).The optimized production of succinic acid was predicted and the interactive effects between glucose,yeast extract,and magnesium carbonate were investigated.As a result,a model for predicting the concentration of succinic acid production was developed.The accuracy of the model was confirmed by the analysis of variance(ANOVA),and the validity was further proved by verification experiments showing that percentage errors between actual and predicted values varied from 3.02%to 6.38%.In addition,it was observed that the interactive effect between yeast extract and magnesium carbonate was statistically significant.In conclusion,RSM is an effective and useful method for optimizing the medium components and investigating the interactive effects,and can provide valuable information for succinic acid scale-up fermentation using A.succinogenes strain BE-1.Yun-jian ZHANG Qiang LI Yu-xiu ZHANG Dan WANG Jian-min XING 2012Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2012,13,2:10
20Internal compared with external drainage of pancreatic duct during pancreaticoduodenectomy: a retrospective study显示文摘Objective: To compare internal with external drainage of the pancreatic duct during pancreaticoduodenectomy with regard to the incidence of postoperative pancreatic fistula(POPF) and other complications.Methods: We retrospectively analyzed 316 patients who underwent pancreaticoduodenectomy with a placed drainage tube(external, n=128; internal, n=188) in the pancreatic duct from 1 January 1999 to 31 December 2011 in Tianjin Third Central Hospital of China. The incidence of POPF and some other complications were compared.Results: There was no difference in the incidence rates of POPF between those given an internal or external drainage tube(P=0.788), but POPF was more severe in the former(P=0.014). Intraperitoneal bleeding rate was also higher in the patients with internal drainage(P=0.040), but operative time and postoperative hospitalization were longer in those with external drainage(P=0.002 and P=0.007, respectively). There was no difference between the groups with regard to the incidence rates of gastrointestinal bleeding, delayed gastric emptying, pulmonary infection, or incision infection and in-hospital mortality.Conclusions: External drainage of the pancreatic duct during pancreaticoduodenectomy can decrease the severity of POPF, but operative time and postoperative hospitalization will be extended.Guangxing Meng Qianzhe Xing Qiang Yuan Zhi Du Yijun Wang Hua Meng 2014Chinese Journal of Cancer Research2014,26,3:8
