| 1 | A highly active VOx-MnOx/CeO_(2) for selective catalytic reduction of NO:The balance between redox property and surface acidity显示文摘Excellent catalysts with low-temperature activity and relatively wide temperature window for selective catalytic reduction of NO with ammonia(NH_(3)-SCR) are highly demanded in view of the practical treatment of NO.Herein,we have designed a highly active VOx-MnOx/CeO_(2) material based on the intrinsic requirement of SCR reaction for catalyst,namely redox sites and surface acid sites.The vanadium oxide and manganese oxide are highly dispersed over the ceria mesosphere via simple incipient wetness impregnation.The loading of manganese could introduce acid sites and enhance the redox property remarkably,while the loading of vanadium increases acid sites and weakens redox property.Through tentatively controlling the appropriate loading ratio of the two components,the optimal catalyst achieves a balance between redox property and surface acidity.The work shed light on the development of new SCR catalyst with superior low temperature activity,wide work temperature window and good hydrothermal stability. | Runnong Yang Zihan Gao Ming Sun Guangying Fu Gao Cheng Wuyuan Liu Xiaobo Yang Xiangyun Zhao Lin Yu | 2021 | Journal of Rare Earths2021，39，11： | 3 |
| 2 | Freestanding Pt nanosheets with high porosity and improved electrocatalytic performance toward the oxygen reduction reaction显示文摘Because of the intriguing electronic properties, high specific surface areas and confinement effect, two-dimensional(2D) noble metal nanosheets usually exhibit fascinating physicochemical properties and thus hold great promises in fuel cell devices and beyond. Herein, 2D porous Pt nanosheets composed by interweaved ultrathin nanowires are successfully fabricated via a facile NaCl-templated process. Controlled experiments demonstrate that the adoption of NaCl and appropriate ratio of NaCl and Pt precursor are indispensable for the formation of porous Pt nanosheets. Impressively, the cost-effective NaCl template can be recyclable through a simple recrystallization procedure, which may greatly reduce the synthetic cost. By virtue of their structural merits, including high porosity, 2D anisotropy and abundant defects, the resultant porous Pt nanosheets exhibit superior activity and enhanced stability towards the oxygen reduction reaction(ORR) compared to the commercial Pt black in alkaline medium. The present study not only offers a high-performance electrocatalyst for fuel cell devices, but also provides a new perspective toward the rational synthesis of 2D noble metal nanosheets with high porosity and diverse functionalities. | Chuang Fan Zihan Huang Xianyu Hu Zhaoping Shi Tianyang Shen Yawen Tang Xiaojun Wang Lin Xu | 2018 | Green Energy & Environment2018，3，4： | 1 |
| 3 | Reinforcement learning based energy efficient robot relay for unmanned aerial vehicles against smart jamming显示文摘Unmanned aerial vehicles(UAVs)with limited energy resources,severe path loss,and shadowing to the ground base stations are vulnerable to smart jammers that aim to degrade the UAV communication performance and exhaust the UAV energy.The UAV anti-jamming communication performance,such as the outage probability,degrades if the robot relay is not aware of the jamming policies and the UAV network topology.In this paper,we propose a robot relay scheme for UAVs against smart jamming,which combines reinforcement learning with a function approximation approach named tile coding,to jointly optimize the robot moving distance and relay power with the unknown jamming channel states and locations.The robot mobility and relay policy are chosen based on the received jamming power,the robot received signal quality,location and energy consumption,and the bit error rate of the UAV messages.We also present a deep reinforcement learning version for the robot with sufficient computing resources.It uses three deep neural networks to choose the robot mobility and relay policy with reduced sample complexity,so as to avoid exploring dangerous policies that lead to the high outage probability of the UAV messages.The network architecture of the three networks is designed with fully connected layers instead of convolutional layers to reduce the computational complexity,which is analyzed by theoretical analyses.We provide the performance bound of the proposed schemes in terms of the bit error rate,robot energy consumption and utility based on a game-theoretic study.Simulation results show that the performance of our proposed relay schemes,including the bit error rate,the outage probability,and the robot energy consumption outperforms the existing schemes. | Xiaozhen LU Jingfang JIE Zihan LIN Liang XIAO Jin LI Yanyong ZHANG | 2022 | Science China(Information Sciences)2022，65，1： | 1 |
| 4 | Random mating mayfly algorithm for RFID network planning显示文摘In order to improve robustness and efficiency of the radio frequency identification(RFID)network,a random mating mayfly algorithm(RMMA)was proposed.Firstly,RMMA introduced the mechanism of random mating into the mayfly algorithm(MA),which improved the population diversity and enhanced the exploration ability of the algorithm in the early stage,and find a better solution to the RFID nework planning(RNP)problem.Secondly,in RNP,tags are usually placed near the boundaries of the working space,so the minimum boundary mutation strategy was proposed to make sure the mayflies which beyond the boundary can keep the original search direction,as to enhance the ability of searching near the boundary.Lastly,in order to measure the performance of RMMA,the algorithm is then benchmarked on three well-known classic test functions,and the results are verified by a comparative study with particle swarm optimization(PSO),grey wolf optimization(GWO),and MA.The results show that the RMMA algorithm is able to provide very competitive results compared to these well-known meta-heuristics,RMMA is also applied to solve RNP problems.The performance evaluation shows that RMMA achieves higher coverage than the other three algorithms.When the number of readers is the same,RMMA can obtain lower interference and get a better load balance in each instance compared with other algorithms.RMMA can also solve RNP problem stably and efficiently when the number and position of tags change over time. | Xie Xiaode Zheng Jiali Lin Zihan He Siyi Feng Minyu | 2022 | The Journal of China Universities of Posts and Telecommunications2022，29，5： | 1 |

| 7 | RFID network planning based on improved brain storm optimization algorithm显示文摘In order to improve the service quality of radio frequency identification(RFID) systems, multiple objectives should be comprehensively considered. An improved brain storm optimization algorithm GABSO, which incorporated adaptive learning operator and golden sine operator into the original brain storm optimization(BSO) algorithm, was proposed to solve the problem of RFID network planning(RNP). GABSO algorithm introduces learning operator and golden sine operator to achieve a balance between exploration and development. Based on GABSO algorithm, an optimization model is established to optimize the position of the reader. The GABSO algorithm was tested on the RFID model and dataset, and was compared with other methods. The GABSO algorithm’s tag coverage was increased by 9.62% over the Cuckoo search(CS) algorithm, and 7.70% over BSO. The results show that the GABSO algorithm could be successfully applied to solve the problem of RNP. | Lin Zihan Zheng Jiali Xie Xiaode Feng Minyu He Siyi | 2022 | The Journal of China Universities of Posts and Telecommunications2022，29，5： | 0 |

| 9 | Well-Dispersed Graphene Enhanced Lithium Complex Grease Toward High-Efcient Lubrication显示文摘Graphene as a lubricating additive holds great potential for industrial lubrication. However, its poor dispersity and compatibility with base oils and grease hinder maximizing performance. Here, the infuence of graphene dispersion on the thickening efect and lubrication function is considered. A well-dispersed lubricant additive was obtained via trihexyl tetradecyl phosphonium bis(2-ethylhexyl) phosphate modifed graphene ([P_(66614)][DEHP]-G). Then lithium complex grease was prepared by saponifcation with 12-OH stearic acid, sebacic acid, and lithium hydroxide, using polyalphaolefn (PAO20) as base oil and the modifed-graphene as lubricating additive, with the original graphene as a comparison. The physicochemical properties and lubrication performance of the as-prepared greases were evaluated in detail. The results show that the as-prepared greases have high dropping point and colloidal stability. Furthermore, modifed-graphene lithium complex grease ofered the best friction reduction and anti-wear abilities, manifesting the reduction of friction coefcient and wear volume up to 18.84% and 67.34%, respectively. With base oil overfow and afux, well-dispersed [P_(66614)][DEHP]-G was readily adsorbed to the worn surfaces, resulting in the formation of a continuous and dense graphene deposition flm. The synergy of deposited graphene-flm, spilled oil, and adhesive grease greatly improves the lubrication function of grease. This research paves the way for modulating high-performance lithium complex grease to reduce the friction and wear of movable machinery. | Kaiyue Lin Zhuang Zhao Yuting Li Zihan Zeng Xiaofeng Wei Xiaoqiang Fan Minhao Zhu | 2023 | Chinese Journal of Mechanical Engineering2023，36，5： | 0 |
| 10 | Submilliwatt, widely tunable coherent microcomb generation with feedback-free operation显示文摘Microcombs are revolutionizing optoelectronics by providing parallel, mutually coherent wavelengthchannels for time-frequency metrology and information processing. To implement this essential function inintegrated photonic systems, it is desirable to drive microcombs directly with an on-chip laser in a simpleand flexible way. However, two major difficulties have prevented this goal: (1) generating mode-lockedcomb states usually requires a significant amount of pump power and (2) the requirement to align laser andresonator frequency significantly complicates operation and limits the tunability of the comb lines. Here, weaddress these problems by using microresonators on an AlGaAs on-insulator platform to generate dark-pulsemicrocombs. This highly nonlinear platform dramatically relaxes fabrication requirements and leads to arecord-low pump power of <1 mW for coherent comb generation. Dark-pulse microcombs facilitated bythermally controlled avoided mode crossings are accessed by direct distributed feedback laser pumping.Without any feedback or control circuitries, the comb shows good coherence and stability. With around150 mW on-chip power, this approach also leads to an unprecedentedly wide tuning range of over one freespectral range (97.5 GHz). Our work provides a route to realize power-efficient, simple, and reconfigurablemicrocombs that can be seamlessly integrated with a wide range of photonic systems. | Haowen Shu Lin Chang Chenghao Lao Bitao Shen Weiqiang Xie Xuguang Zhang Ming Jin Yuansheng Tao Ruixuan Chen Zihan Tao Huajin Chang Shaohua Yu Qifan Yang Xingjun Wang John E.Bowers | 2023 | Advanced Photonics2023，5，3： | 0 |
| 11 | Correlation knowledge extraction based on data mining for distribution network planning显示文摘Traditional distribution network planning relies on the professional knowledge of planners,especially when analyzing the correlations between the problems existing in the network and the crucial influencing factors.The inherent laws reflected by the historical data of the distribution network are ignored,which affects the objectivity of the planning scheme.In this study,to improve the efficiency and accuracy of distribution network planning,the characteristics of distribution network data were extracted using a data-mining technique,and correlation knowledge of existing problems in the network was obtained.A data-mining model based on correlation rules was established.The inputs of the model were the electrical characteristic indices screened using the gray correlation method.The Apriori algorithm was used to extract correlation knowledge from the operational data of the distribution network and obtain strong correlation rules.Degree of promotion and chi-square tests were used to verify the rationality of the strong correlation rules of the model output.In this study,the correlation relationship between heavy load or overload problems of distribution network feeders in different regions and related characteristic indices was determined,and the confidence of the correlation rules was obtained.These results can provide an effective basis for the formulation of a distribution network planning scheme. | Zhifang Zhu Zihan Lin Liping Chen Hong Dong Yanna Gao Xinyi Liang Jiahao Deng | 2023 | Global Energy Interconnection2023，6，4： | 0 |
| 12 | Improved sparrow search algorithm for RFID network planning显示文摘To solve the problem that the performance of the coverage,interference rate,load balance andweak power in the radio frequency identification(RFID)network planning.This paper proposes an elite opposition-based learning and Lévy flight sparrow search algorithm(SSA),which is named elite opposition-based learning and Levy flight SSA(ELSSA).First,the algorithm initializes the population by an elite opposed-based learning strategy to enhance the diversity of the population.Second,Lévy flight is introduced into the scrounger’s position update formula to solve the situation that the algorithm falls into the local optimal solution.It has a probability that the current position is changed by Lévy flight.This method can jump out of the local optimal solution.In the end,the proposed method is compared with particle swarm optimization(PSO)algorithm,grey wolf optimzer(GWO)algorithm and SSA in the multiple simulation tests.The simulated results showed that,under the same number of readers,the average fitness of the ELSSA is improved respectively by 3.36%,5.67%and 18.45%.By setting the different number of readers,ELSSA uses fewer readers than other algorithms.The conclusion shows that the proposed method can ensure a satisfying coverage by using fewer readers and achieving higher comprehensive performance. | Zhang Jiangbo Zheng Jiali Quan Yixuan Lin Zihan Xie Xiaode | 2023 | The Journal of China Universities of Posts and Telecommunications2023，30，1： | 0 |
| 13 | The existence of a nonclassical TCA cycle in the nucleus that wires the metabolic-epigenetic circuitry显示文摘The scope and variety of the metabolic intermediates from the mitochondrial tricarboxylic acid(TCA)cycle that are engaged in epigenetic regulation of the chromatin function in the nucleus raise an outstanding question about how timely and precise supply/consumption of these metabolites is achieved in the nucleus.We report here the identification of a nonclassical TCA cycle in the nucleus(nTCA cycle).We found that all the TCA cycle-associated enzymes including citrate synthase(CS),aconitase 2(ACO2),isocitrate dehydrogenase 3(IDH3),oxoglutarate dehydrogenase(OGDH),succinyl-CoA synthetase(SCS),fumarate hydratase(FH),and malate dehydrogenase 2(MDH2),except for succinate dehydrogenase(SDH),a component of electron transport chain for generating ATP,exist in the nucleus.We showed that these nuclear enzymes catalyze an incomplete TCA cycle similar to that found in cyanobacteria.We propose that the nTCA cycle is implemented mainly to generate/consume metabolic intermediates,not for energy production.We demonstrated that the nTCA cycle is intrinsically linked to chromatin dynamics and transcription regulation.Together,our study uncovers the existence of a nonclassical TCA cycle in the nucleus that links the metabolic pathway to epigenetic regulation. | Xujun Liu Wenzhe Si Lin He Jianguo Yang Yani Peng Jie Ren Xiaoping Liu Tong Jin Huajing Yu Zihan Zhang Xiao Cheng Wenting Zhang Lu Xia Yunchao Huang Yue Wang Shumeng Liu Lin Shan Yu Zhang Xiaohan Yang Haixia Li Jing Liang Luyang Sun Yongfeng Shang | 2021 | Signal Transduction and Targeted Therapy2021，6，12： | 0 |
| 14 | Age-related changes in prevalence and symptom characteristics in kidney deficiency syndrome with varied health status:a cross-sectional observational study显示文摘Objective:This study aimed to reveal the age-related changes in prevalence and symptom characteristics in kidney deficiency syndrome(KDS)with varied health status.Methods:This cross-sectional observational study was conducted in6 hospitals.Investigators queried participants aged 20e79 about their health,including symptoms if any,and completed questionnaires to collect participants responses.Prevalence,severity,and frequency of KDS and other relevant parameters were observed and recorded.Comparative analysis of countable variables,including prevalence,was performed by frequency analysis and c2 test and expressed as a composite ratio.Comparative analysis of quantitative scores of the severity and frequency of symptoms was performed by the rank-sum test.Regression analysis of the correlation of KDS with potential contributing factors was performed by non-conditional binary logistic stepwise regression of numerical variables.Results:Prevalence of KDS in healthy and unhealthy participants correlated with increasing age(P<0.05).In those with chronic disease,KDS prevalence was comparatively high,but the trend was not obvious.KDS prevalence in participants age 20e39 showed an increasing trend with deteriorating health(P<0.05).Compared to healthy individuals,KDS prevalence in subhealthy persons and those with chronic disease showed an increasing trend(P<0.05)in the 40e59 and 60e79 age groups,whereas there was no difference between subhealthy persons and those with chronic disease age 40e59 and 60e79.Symptom severity scores of KDS showed an increasing trend with increasing age and deteriorating health status(P<0.05).Higher symptom frequency scores were also positively correlated with increasing age(P<0.05),but health status deterioration was not significantly correlated(P>0.05).Age,health status,lower back pain,shin soreness or heel pain,tinnitus or deafness,hair loss or loose teeth,incomplete bladder emptying or incontinence,and sexual dysfunction or infertility were potential factors contributing to KDS(P<0.05),but age was the only independent variable for which OR>1.Moreover,the distribution of typical KDS-related symptoms showed dramatic regularities.Conclusion:Prevalence and symptom characteristics of KDS were found to increase consistently with increasing age and deteriorating health status.Kidney deficiency may be an important mechanism of aging in the subhealthy and chronic disease states. | Yin Zhang Yue Liu Xianping Li Yuezhou Chen Hui Ye Xiaofeng Li Zihan Lin Zheng Wang Wei Huang Xia Ding | 2014 | Journal of Traditional Chinese Medical Sciences2014，1，1： | 0 |
| 15 | RFID indoor positioning based on semi-supervised actor-critic co-training显示文摘For large-scale radio frequency identification(RFID) indoor positioning system, the positioning scale is relatively large, with less labeled data and more unlabeled data, and it is easily affected by multipath and white noise. An RFID positioning algorithm based on semi-supervised actor-critic co-training(SACC) was proposed to solve this problem. In this research, the positioning is regarded as Markov decision-making process. Firstly, the actor-critic was combined with random actions and the unlabeled best received signal arrival intensity(RSSI) data was selected by co-training of the semi-supervised. Secondly, the actor and the critic were updated by employing Kronecker-factored approximation calculate(K-FAC) natural gradient. Finally, the target position was obtained by co-locating with labeled RSSI data and the selected unlabeled RSSI data. The proposed method reduced the cost of indoor positioning significantly by decreasing the number of labeled data. Meanwhile, with the increase of the positioning targets, the actor could quickly select unlabeled RSSI data and updates the location model. Experiment shows that, compared with other RFID indoor positioning algorithms, such as twin delayed deep deterministic policy gradient(TD3), deep deterministic policy gradient(DDPG), and actor-critic using Kronecker-factored trust region(ACKTR), the proposed method decreased the average positioning error respectively by 50.226%, 41.916%, and 25.004%. Meanwhile, the positioning stability was improved by 23.430%, 28.518%, and 38.631%. | Li Li Zheng Jiali Quan Yixuan Lin Zihan Li Yingchao Huang Tianxing | 2020 | The Journal of China Universities of Posts and Telecommunications2020，27，5： | 0 |

| 18 | Ectopic expression of poplar gene PsnERF138 in tobacco confers salt stress tolerance and growth advantages显示文摘The AP2/ERF family is one of the largest plant-specific transcription factors and plays a vital role in plant growth and stress response.In this study,PsnERF138 was cloned from Populus alba×Populus glandulosa and transformed into tobacco using the Agrobacterium-mediated transformation method.PsnERF138 was localized in the nucleus through subcellular localization assay in tobacco.Under normal conditions,the root lengths of PsnERF138 transgenic lines were much longer than those of wild type.Under salt stress,the transgenic tobacco lines over-expressing PsnERF138 showed a significant increase in seed germination rate,plant height,and root length,compared to control plants.In addition,the transgenic tobacco lines displayed some advantages at the physiological level,such as higher superoxide dismutase(SOD)activity,peroxidase(POD)activity,proline content,and lower malondialdehyde(MDA)content,as compared to those in the control plants.Histochemical staining also showed that the transgenic tobacco lines had lower reactive oxygen species(ROS)accumulation,compared to control plants under salt stress.The combined results indicate that poplar PsnERF138 plays a contributing role in augmenting salt tolerance and conferring multiple growth advantages as being overexpressed in tobacco. | Lin Liu Zihan Cheng Wenjing Yao Xueyi Wang Fenglin Jia Boru Zhou Tingbo Jiang | 2021 | Forestry Research2021，1，1： | 0 |
| 19 | Hybrid gray wolf optimization-cuckoo search algorithm for RFID network planning显示文摘In recent years,with the rapid development of Internet of things(IoT)technology,radio frequency identification(RFID)technology as the core of IoT technology has been paid more and more attention,and RFID network planning(RNP)has become the primary concern.Compared with the traditional methods,meta-heuristic method is widely used in RNP.Aiming at the target requirements of RFID,such as fewer readers,covering more tags,reducing the interference between readers and saving costs,this paper proposes a hybrid gray wolf optimization-cuckoo search(GWO-CS)algorithm.This method uses the input representation based on random gray wolf search and evaluates the tag density and location to determine the combination performance of the reader's propagation area.Compared with particle swarm optimization(PSO)algorithm,cuckoo search(CS)algorithm and gray wolf optimization(GWO)algorithm under the same experimental conditions,the coverage of GWO-CS is 9.306%higher than that of PSO algorithm,6.963%higher than that of CS algorithm,and 3.488%higher than that of GWO algorithm.The results show that the GWO-CS algorithm cannot only improve the global search range,but also improve the local search depth. | Quan Yixuan Zheng Jiali Xie Xiaode Lin Zihan Luo Wencong | 2021 | The Journal of China Universities of Posts and Telecommunications2021，28，6： | 0 |
