1Research on the Effect Evaluation of Protected Space Driving New Technologies Industrialization from the Perspective of ST显示文摘Based on the perspective of sustainability transitions(ST)theory,the paper dissects the opera-tional mechanisms of protected space driving emerging technology industrialization from an external system perspective,which is on the basis of defining essential characteristics and func-tional attributes of protected space.Meanwhile,it structures a three-dimensional evaluation model of protected space from the perspective of internal mechanism by introducing the policy mixes method.Finally,taking the Chinese New Energy Vehicle(NEV)industry as the example and using the system dynamics modeling method,the paper designs different simulation schemes from three dimensions of horizontal evolution trend,three types of policy instrument change and policy mixes of protected space,to predict and analyze the operation effect of protected space.The results show that the Chinese NEV industry is in the stage of market niche entry,and corresponding measures should be taken to increase the market scale,form effective demand and scale effect,and promote the diffusion of market niche;the effect of policy mixes is better than that of the single policy instrument;specific policy mixes should be adopted to develop simultaneously from both the supply and demand sides to improve the industrialization level of NEV.LIU Yixin OU Chunyao ZHANG Guangyu LIANG Xiao 2020Journal of Systems Science & Complexity2020,33,2:8
2Synthesis of HTLcs modified by K_(3)PO_(4) for side chain alkylation of toluene with methanol显示文摘A series of calcined HTLcs catalysts were prepared and modified with potassium phosphate by impregnation method to clarify the influence of catalyst alkalinity on the side chain alkylation of toluene with methanol for synthesis of ethylbenzene and styrene.The catalysts were characterized by X-ray diffraction(XRD),N_(2)physical adsorption-desorption,Fourier-transform infrared spectroscopy(FT-IR),Scanning electron microscopy(SEM),X-ray photoelectron spectrometry(XPS),NH_(3)temperature-programmed desorption(NH_(3)-TPD)and CO_(2)temperature-programmed desorption(CO_(2)-TPD).It was found that the selectivity of styrene was highest(39.25%)when the K_(3)PO_(4)loading was 7.5 wt%.And the total yield of styrene and ethylbenzene could reach 65.08%with 10 wt%K_(3)PO_(4)loading.This might due to the fact that the addition of K_(3)PO_(4)could adjust the acid and basic sites of catalysts.In addition,appropriate strength and amount of basic sites were favorable to producing more styrene.Chunyao Hao Yueli Wen Bin Wang Faraz Ahmad Yuhua Liu Huijun Li Wei Huang 2021Green Energy & Environment2021,6,6:6
3Implementation of regional Acute Stroke Care Map increases thrombolysis rates for acute ischaemic stroke in Chinese urban area in only 3 months显示文摘Background The rate of intravenous thrombolysis for acute ischaemic stroke remains low in China.We investigated whether the implementation of a citywide Acute Stroke Care Map(ASCaM)is associated with an improvement of acute stroke care quality in a Chinese urban area.Methods The ASCaM comprises 10 improvement strategies and has been implemented through a network consisting of 20 tertiary hospitals.We identified 7827 patients with ischaemic stroke admitted from April to October 2017,and 506 patients underwent thrombolysis were finally included for analysis.Results Compared with‘pre-ASCaM period’,we observed an increased rate of administration of tissue plasminogen activator within 4.5 hours(65.4% vs 54.5%;adjusted OR,1.724;95% CI 1.21 to 2.45;p=0.003)during‘ASCaM period’.In multivariate analysis models,‘ASCaM period’was associated with a significant reduction in onset-to door time(114.1±55.7 vs 135.7±58.4 min,p=0.0002)and onset-to needle time(ONT)(169.2±58.1 vs 195.6±59.3 min,p<0.0001).Yet no change was found in door-to needle time.Clinical outcomes such as symptomatic intracranial haemorrhage,favourable functional outcome(modified Rankin Scale≤2)and in-hospital mortality remained unchanged.Conclusion The implementation of ASCaM was significantly associated with increased rates of intravenous thrombolysis and shorter ONT.The ASCaM may,in proof-of principle,serve as a model to reduce treatment delay and increase thrombolysis rates in Chinese urban areas and possibly other highly populated Asian regions.Yi Sui Jianfeng Luo Chunyao Dong Liqiang Zheng Weijin Zhao Yao Zhang Ying Xian Huaguang Zheng Bernard Yan Mark Parsons Li Ren Ying Xiao Haoyue Zhu Lijie Ren Qi Fang Yi Yang Weidong Liu Bing Xu 2021Stroke & Vascular Neurology2021,6,1:4
4Injectable self-healing polysaccharide hydrogel loading CuS and pH-responsive DOX@ZIF-8 nanoparticles for synergistic photothermal-photodynamic-chemo therapy of cancer显示文摘The injectable self-healing polysaccharide hydrogel was prepared by the formation of Schiff base bonds between aldehyde-modified methylcellulose(MC–CHO)and carboxymethyl chitosan(CMC).The copper sulfide nanoparticles(CuS NPs)and pH-sensitive doxorubicin-loaded zeolitic imidazolate frameworks nanoparticles(DOX@ZIF-8 NPs)were prepared and could be well-dispersed into the hydrogel system.The presence of CuS NPs can achieve photothermal therapy(PTT)for tumors under the irradiation of the near-infrared(NIR)laser.Moreover,CuS NPs can generate photodynamic effects under NIR irradiation,converting oxygen into toxic reactive oxygen species(ROS)and presenting efficient photodynamic therapy(PDT).The DOX@ZIF-8 NPs can be decomposed under an intracellular acidic environment and realize the controlled release of DOX.The injectable self-healing hydrogel loading Cu S and DOX@ZIF-8 NPs can achieve synergistic photothermal-photodynamic-chemo therapy for tumors and will inspire the researchers to construct a platform from hydrogel combined with multifunctional nanomaterials to realize the effective multimodal therapy for tumor.Zhiyi Qian Nuoya Zhao Chunyao Wang Weizhong Yuan 2022Journal of Materials Science & Technology2022,,32:2

13Attitude control of apricot during orientation transmission显示文摘The kinetic characteristics of apricots during orientation transmission were studied to provide a basis for improving the structure of the transmission device.Previous studies have generally focused on the development of orientation devices,but few studies have been conducted to analyze the mechanisms of orientation.In order to study the attitude control in the orientation mechanisms,an orthogonal combination test was performed and a rigid kinetic model for a monosymmetric apricot was developed based on Euler’s kinetic equations with the modified Rodrigue parameters(MRPs).Kinetic simulation and analysis based upon the attitude control law were conducted and an attitude control simulation platform was created.The simulation results showed that the orientation transmission system for monosymmetric apricots was globally convergent and tended to stable.The experimental torques also affected the orientation success rates.The calculated average experimental torque value(0.164 N·m)was consistent with the maximum control torque value(0.16478 N·m)when the system was in a stable state in Simulink.The consistency between the simulation result and the calculated control torque validates the correctness of the designed control torques.Ding Xiangyan Wang Chunyao Huang Chunyang Luo Jianqing 2016International Journal of Agricultural and Biological Engineering2016,9,5:1

20An intelligent target detection method of UAV swarms based on improved KM algorithm显示文摘Complete and efficient detection of unknown targets is the most popular application of UAV swarms. Under most situations, targets have directional characteristics so that they can only be successfully detected within specific angles. In such cases, how to coordinate UAVs and allocate optimal paths for them to efficiently detect all the targets is the primary issue to be solved. In this paper, an intelligent target detection method is proposed for UAV swarms to achieve real-time detection requirements. First, a target-feature-information-based disintegration method is built up to divide the search space into a set of cubes. Theoretically, when the cubes are traversed, all the targets can be detected. Then, a Kuhn-Munkres(KM)-algorithm-based path planning method is proposed for UAVs to traverse the cubes. Finally, to further improve search efficiency, a 3 D realtime probability map is established over the search space which estimates the possibility of detecting new targets at each point. This map is adopted to modify the weights in KM algorithm, thereby optimizing the UAVs’ paths during the search process. Simulation results show that with the proposed method, all targets, with detection angle limitations, can be found by UAVs. Moreover, by implementing the 3 D probability map, the search efficiency is improved by 23.4%–78.1%.Xiangming ZHENG Chunyao MA 2021Chinese Journal of Aeronautics2021,34,2:1
