| 1 | Modified Cuckoo Search Algorithm to Solve Economic Power Dispatch Optimization Problems显示文摘A modified cuckoo search(CS) algorithm is proposed to solve economic dispatch(ED) problems that have nonconvex, non-continuous or non-linear solution spaces considering valve-point effects, prohibited operating zones, transmission losses and ramp rate limits. Comparing with the traditional cuckoo search algorithm, we propose a self-adaptive step size and some neighbor-study strategies to enhance search performance.Moreover, an improved lambda iteration strategy is used to generate new solutions. To show the superiority of the proposed algorithm over several classic algorithms, four systems with different benchmarks are tested. The results show its efficiency to solve economic dispatch problems, especially for large-scale systems. | Jian Zhao Shixin Liu Mengchu Zhou Xiwang Guo Liang Qi | 2018 | IEEE/CAA Journal of Automatica Sinica2018，5，4： | 14 |
| 2 | Cooperative differential games guidance laws for multiple attackers against an active defense target显示文摘This paper is concerned with a scenario of multiple attackers trying to intercept a target with active defense.Three types of agents are considered in the guidance:The multiple attackers,the target and the defender,where the attackers aim to pursuit the target from different directions and evade from the defender simultaneously.The guidance engagement is formulated in the framework of a zero-sum two-person differential game between the two opposing teams,such that the measurements on the maneuver of the target or estimations on the defending strategy of the defender can be absent.Cooperation of the attackers resides in two aspects:redundant interception under the threat of the defender and the relative intercept geometry with the target.The miss distances,the relative intercept angle errors and the costs of the agents are combined into a single performance index of the game.Such formulation enables a unitary approach to the design of guidance laws for the agents.To minimize the control efforts and miss distances for the attackers,an optimization method is proposed to find the best anticipated miss distances to the defender under the constraint that the defender is endowed with a capture radius.Numerical simulations with two cases are conducted to illustrate the effectiveness of the proposed cooperative guidance law. | Fei LIU Xiwang DONG Qingdong LI Zhang REN | 2022 | Chinese Journal of Aeronautics2022，35，5： | 5 |
| 3 | Incidence and prevalence of moyamoya disease in urban China: a nationwide retrospective cohort study显示文摘Background and objective Moyamoya disease(MMD)is an increasingly recognised cause of stroke,mainly described in East Asia.China is the largest nation in Asia,but few studies reported the epidemiology of MMD,especially at a national level.We aimed to estimate the incidence and prevalence of MMD in China.Methods We performed a population-based study using data from the national databases of Urban Basic Medical Insurance between 2013 and 2016,covering approximately 0.50 billion individuals.MMD cases were identified by diagnostic code(International Classification of Diseases,10th Revision I67.5)or related diagnostic text.Results A total of 1987 MMD patients(mean age 44.45±14.30 years,female-to male ratio 1.12)were identified,representing a national crude incidence of 0.59(95%CI:0.49 to 0.68)and a prevalence of 1.01(95%CI:0.81 to 1.21)per 100000 person-years in 2016.Rates were higher in females than in males for the incidence(0.66 vs 0.52)and prevalence(1.05 vs 0.90).And the age-specific rates showed a bimodal distribution,with the highest peak in middle-aged group and the second peak in child group.Conclusions Our results confirm that MMD is relatively common in East Asians,but the rates in China were lower than those in other East Asian countries such as Japan and Korea.The unique epidemiological features,including a relatively weak female predominance and a shift in the highest peak of incidence from children to adults,revealed new sight into MMD.Further research is expected to explore the potential pathogenesis of MMD. | Yixin Sun Guoyu Zhou Jingnan Feng Lu Chen Guozhen Liu Jinxi Wang Qingliang Wang Junyou Yu Xiwang Yang Zheng Yang Pei Gao Shengfeng Wang Siyan Zhan | 2021 | Stroke & Vascular Neurology2021，6，4： | 4 |

| 5 | Chlorine-anion doping induced multi-factor optimization in perovskites for boosting intrinsic oxygen evolution显示文摘The oxygen evolution reaction(OER) plays a crucial role in many electrochemical energy technologies,and creating multiple beneficial factors for OER catalysis is desirable for achieving high catalytic efficiency.Here,we highlight a new halogen-chlorine(Cl)-anion doping strategy to boost the OER activity of perovskite oxides.As a proof-of-concept,proper Cl doping at the oxygen site of LaFeO3(LFO) perovskite can induce multiple favorable characteristics for catalyzing the OER,including rich oxygen vacancies,increased electrical conductivity and enhanced Fe-O covalency.Benefiting from these factors,the LaFeO2.9-δCl0.1(LFOCl) perovskite displays significant intrinsic activity enhancement by a factor of around three relative to its parent LFO.This work uncovers the effect of Cl-anion doping in perovskites on promoting OER performance and paves a new way to design highly efficient electrocatalysts. | Yinlong Zhu Qian Lin Zhenbin Wang Dongchen Qi Yichun Yin Yu Liu Xiwang Zhang Zongping Shao Huanting Wang | 2021 | Journal of Energy Chemistry2021，30，1： | 2 |

| 14 | A homogenization-planning-tracking method to solve cooperative autonomous motion control for heterogeneous carrier dispatch systems显示文摘Taxiing aircraft and towed aircraft with drawbar are two typical dispatch modes on the flight deck of aircraft carriers. In this paper, a novel hierarchical solution strategy, named as the Homogenization-Planning-Tracking(HPT) method, to solve cooperative autonomous motion control for heterogeneous carrier dispatch systems is developed. In the homogenization layer, any towed aircraft system involved in the sortie task is abstracted into a virtual taxiing aircraft. This layer transforms the heterogeneous systems into a homogeneous configuration. Then in the planning layer, a centralized optimal control problem is formulated for the homogeneous system. Compared with conducting the path planning directly with the original heterogeneous system, the homogenization layer contributes to reduce the dimension and nonlinearity of the formulated optimal control problem in the planning layer and consequently improves the robustness and efficiency of the solution process. Finally, in the tracking layer, a receding horizon controller is developed to track the reference trajectory obtained in the planning layer. To improve the tracking performance,multi-objective optimization techniques are implemented offline in advance to determine optimal weight parameters used in the tracking layer. Simulations demonstrate that smooth and collision-free cooperative trajectory can be generated efficiently in the planning phase. And robust trajectory tracking can be realized in the presence of external disturbances in the tracking phase.The developed HPT method provides a promising solution to the autonomous deck dispatch for unmanned carrier aircraft in the future. | Jie LIU Xianzhou DONG Xinwei WANG Kaikai CUI Xiwang QIE Jun JIA | 2022 | Chinese Journal of Aeronautics2022，35，9： | 0 |

| 16 | Tunnelling of electrons via the neighboring atom显示文摘As compared to the intuitive process that the electron emits straight to the continuum from its parent ion,there is an alternative route that the electron may transfer to and be trapped by a neighboring ionic core before the eventual release.Here,we demonstrate that electron tunnelling via the neighboring atomic core is a pronounced process in light-induced tunnelling ionization of molecules by absorbing multiple near-infrared photons.We devised a siteresolved tunnelling experiment using an Ar-Kr+ion as a prototype system to track the electron tunnelling dynamics from the Ar atom towards the neighboring Kr+by monitoring its transverse momentum distribution,which is temporally captured into the resonant excited states of the Ar-Kr+before its eventual releasing.The influence of the Coulomb potential of neighboring ionic cores promises new insights into the understanding and controlling of tunnelling dynamics in complex molecules or environment. | Ming Zhu Jihong Tong Xiwang Liu Weifeng Yang Xiaochun Gong Wenyu Jiang Peifen Lu Hui Li Xiaohong Song Jian Wu | 2024 | Light(Science & Applications)2024，13，1： | 0 |
| 17 | Screening for congenital heart defects: diversified strategies in current China显示文摘background Congenital heart defects(CHD)is the most common type of birth defect and a leading cause of infant mortality in China.Detection of CHD during newborn is still challenging.The contradiction between the increasingly mature technology of diagnosis and treatment and the inability of early detection is the biggest current dilemma.A few pilot studies attempt to establish the universal screening for CHD in newborns;however,the rate of misdiagnosis is still high in most Chinese hospitals,especially in some undeveloped middle-western regions.Data sources Based on the recent publications on screening of congenital heart diseases in China.We reviewed the use of diversified screening strategies in current China.results Prenatal diagnosis by fetal echocardiography and postnatal detection by pulse oximetry combined with clinical assessment are the useful methods for CHD screening in most areas.The altitude should be taken into account when using pulse oximetry in the middle-western areas of China,where the incidence of CHD maybe higher.Echocardiography is suitable for CHD screening in almost all areas but it could add to financial burden in the developing regions.Genetic analysis could assist clinical doctors to perform more earlier screening and give better counseling regarding the outcome.Due to disparities in economic and medical resources,the screening system should be carried out from multiple perspectives according to the present economic development.Notably,follow-up is an important issue in the screening of CHD,especially for the asymptomatic babies who discharged home.Policies should be formulated to address the epidemiology of CHD in deprived areas to better allocate medical resources and to develop local training programmes to screen and diagnose CHD.Conclusions Diversified strategies are available in current China.The two-indicator method for CHD screening is recommended to be implemented in routine postnatal care.We can do more in screening for CHD in the future. | Xiwang Liu Weize Xu Jiangen Yu Qiang Shu | 2019 | World Journal of Pediatric Surgery2019，2，1： | 0 |
