| 1 | Characteristics of gas-solid micro fluidized beds for thermochemical reaction analysis显示文摘Fuel conversion and clean energy reaction systems involve a variety of catalytic and non-catalytic gas-solid thermochemical reactions.A good understanding of the correct reaction mechanism and kinetics,as well as the profiles of reaction products,is of great significance to the development,design,and operation of such reaction systems.The micro fluidized bed reaction analysis provides an efficient and reliable method to acquire this essential information with low capital and operating costs,low energy consumption and enhanced safety.This paper provides an overview of the system and its characteristics for the micro fluidized bed reaction analyzer that has been well proven to be a reliable new approach as well as an instrument for characterizing various gas-solid thermochemical reactions. | Zhennan Han Junrong Yue Xi Zeng Jian Yu Fang Wang Shaozeng Sun Hong Yao Guangqian Luo Xuejing Liu Yining Sun Fu Ding Liangliang Fu Lei Shi Kangjun Wang Jiebin Yang Shaonan Wang Xueqing Chen Dingrong Bai Guangwen Xu | 2020 | Carbon Resources Conversion2020，3，1： | 6 |

| 4 | Triple oxygen isotope constraints on the origin of ocean island basalts显示文摘Understanding the origin of ocean island basalts(OIB) has important bearings on Earth's deep mantle.Although it is widely accepted that subducted oceanic crust, as a consequence of plate tectonics, contributes material to OIB's formation, its exact fraction in OIB's mantle source remains ambiguous largely due to uncertainties associated with existing geochemical proxies. Here we show, through theoretical calculation, that unlike many known proxies, triple oxygen isotope compositions(i.e.D^(17 )O) in olivine samples are not affected by crystallization and partial melting. This unique feature, therefore, allows olivine D^(17 )O values to identify subducted oceanic crusts in OIB's mantle source. Furthermore, the fractions of subducted ocean sediments and hydrothermally altered oceanic crust in OIB's mantle source can be quantified using their characteristic D^(17 )O values. Based on published D^(17 )O data, we estimated the fraction of subducted oceanic crust to be as high as 22.3% in certain OIB, but the affected region in the respective mantle plume is likely to be limited. | Xiaobin Cao Huiming Bao Caihong Gao Yun Liu Fang Huang Yongbo Peng Yining Zhang | 2019 | Acta Geochimica2019，38，3： | 1 |
| 5 | Beliefs towards the COVID-19 pandemic among patients with emotional disorders in China显示文摘Background The novel coronavirus disease 2019(COVID-19)pandemic has given rise to fear and panic in the public.Although hospitals in China reduced outpatient visits and restricted inpatient admission to lower the risk of transmission of COVID-19,this has significantly affected patients in need of medical attention,for example,patients with emotional disorders.Aims This study aimed to compare the beliefs towards COVID-19 among outpatients with emotional disorders(ie,anxiety or depression)with those offamily caregivers and the general public and examine factors that shape the beliefs towards COVID-19 among outpatients with emotional disorders.Methods Survey data from 570 outpatients with anxiety or depression disorders,449 family caregivers and 470 general public subjects were collected.Multiple stepwise regression analyses were used to describe participants'level of concern,prevention atitude and positive expectations towards the COVID-19 outbreak.Results About 70.9%of outpatients had to postpone their mental health treatment;43.2%of patients admitted that their mental health was adversely affected by the COVID-19 outbreak--these patients tended to be older,male and less educated.After controlling for age and education level,outpatients with emotional disorders had significantly lower levels of concerns but more negative expectations towards COVID-19,compared with family caregivers and the public.Multivariate linear stepwise regression analysis showed that age,education and the perception of the impact of COVID-19 on one's existing mental ilness were significantly associated with outpatients'beliefs about the epidemic.Conclusion Outpatients with anxiety or depression disorders were relatively less focused on the COVID-19 outbreak,but the impact of the infection was found to be independently associated with their beliefs towards COVID-19.In addition,outpatients who were older and of low educational levels particularly held more negative beliefs about the epidemic,which may place them at a higher risk for poor mental health. | Yining Gao Fei Sun Wenwen Jiang Yuan Fang Ling Yue Xiang Lin Xia Li | 2020 | General Psychiatry2020，33，3： | 1 |

| 7 | Sentiment Analysis for MOOC Course Reviews显示文摘Currently,increasing users are using MOOC platforms to choose courses and leave text comments with emotional overtones.The traditional words vector representationmethod uses static method to extract text information,which ignores the text position information.The traditional convolutional neural network fails to make full use of the semantic features and association information of the text between channels,which will cause inaccurate text sentiment classification.In order to solve the problems,a text classification model based on Albert and Capsule Network and attention mechanism is proposed.The model was verified on the MOOC comment data set,and compared with the traditional user comment sentiment analysis model.The results show the accuracy of the model was improved to a certain extent. | Tianyi Liu Wei Hu Fang Liu Yining Li | 2021 | 国际计算机前沿大会会议论文集2021，，2： | 0 |
| 8 | Cu_(1)-B dual-active sites catalysts for the efficient dehydrogenative coupling and CO_(2)electroreduction显示文摘Dual-active sites(DASs)catalysts have positive potential applications in broad fields because of their specific active sites and synergistic catalytic effects.Therefore,the controllable synthesis and finely regulating the activity of such catalysts has become a hot research area for now.In this work,we developed a pyrolysis-etching-hydrogen activation strategy to prepare the DASs catalysts involving single-atom Cu and B on N-doped porous carbon material(Cu_(1)-B/NPC).Numerous systematic characterization and density functional theoretical(DFT)calculation results showed that the Cu and B existed as Cu-N4 porphyrinlike unit and B-N_(3)unit in the obtained catalyst.DFT calculations further revealed that single-atom Cu and B sites were linked by bridging N atoms to form the Cu_(1)-B-N6 dual-sites.The Cu_(1)-B/NPC catalyst was more effective than the single-active site catalysts with B-N_(3)sites in NPC(B/NPC)and Cu-N4 porphyrin-like sites in NPC(Cu_(1)/NPC),respectively,for the dehydrogenative coupling of dimethylphenylsilane(DiMPSH)with various alcohols,performing the great activity(>99%)and selectivity(>99%).The catalytic performances of the Cu_(1)-B/NPC catalyst remained nearly unchanged after five cycles,also indicating its outstanding recyclability.DFT calculations showed that the Cu_(1)-B-N6 dual-sites exhibited the lowest energy profile on the potential energy surface than that of sole B-N_(3)and Cu-N4 porphyrin-like sites.Furthermore,the rate-limiting step of dehydrogenation of DiMPSH on Cu_(1)-B-N6 dual-sites also showed a much lower activation energy than the other two single sites.Benefitting from the superiority of the Cu_(1)-B-N6 dual-sites,the Cu_(1)-B/NPC catalyst can also be used for CO_(2)electroreduction to produce syngas.Thus,DASs catalysts are promising to achieve multifunctional catalytic properties and have aroused positive attention in the field of catalysis. | Konglin Wu Zhaobin Fang Cheng Peng Yining Zhang Binbin Jiang Yanshang Kang Zhiming Chen Mingfu Ye Yuxi Wu Xianwen Wei Shoujie Liu Sha Li Jian Zhang | 2023 | Nano Research2023，16，4： | 0 |
| 9 | Search for d-MPs without duplicates in two-terminal multistate networks based on MPs显示文摘The reliability evaluation of a multistate network is primarily based on d-minimal paths/cuts(d-MPs/d-MCs).However,being a nondeterminism polynomial hard(NP-hard)problem,searching for all d-MPs is a rather challenging task.In existing implicit enumeration algorithms based on minimal paths(MPs),duplicate d-MP candidates may be generated.An extra step is needed to locate and remove these duplicate d-MP candidates,which costs significant computational effort.This paper proposes an efficient method to prevent the generation of duplicate d-MP candidates for implicit enumeration algorithms for d-MPs.First,the mechanism of generating duplicate d-MP candidates in the implicit enumeration algorithms is discussed.Second,a direct and efficient avoiding-duplicates method is proposed.Third,an improved algorithm is developed,followed by complexity analysis and illustrative examples.Based on the computational experiments comparing with two existing algorithms,it is found that the proposed method can significantly improve the efficiency of generating d-MPs for a particular demand level d. | XU Bei FANG Yining BAI Guanghan ZHANG Yun’an TAO Junyong | 2022 | Journal of Systems Engineering and Electronics2022，33，6： | 0 |
| 10 | Dynamic Investigations on the Wear Behavior of a 3D Revolute Joint Considering Time-Varying Contact Stiffness: Simulation and Experiment显示文摘The existence of the relative radial and axial movements of a revolute joint’s journal and bearing is widely known.The three-dimensional(3D)revolute joint model considers relative radial and axial clearances;therefore,the freedoms of motion and contact scenarios are more realistic than those of the two-dimensional model.This paper proposes a wear model that integrates the modeling of a 3D revolute clearance joint and the contact force and wear depth calculations.Time-varying contact stiffness is first considered in the contact force model.Also,a cycle-update wear depth calculation strategy is presented.A digital image correlation(DIC)non-contact measurement and a cylindricity test are conducted.The measurement results are compared with the numerical simulation,and the proposed model’s correctness and the wear depth calculation strategy are verified.The results show that the wear amount distribution on the bearing’s inner surface is uneven in the axial and radial directions due to the journal’s stochastic oscillations.The maximum wear depth locates where at the bearing’s edges the motion direction of the follower shifts.These find-ings help to seek the revolute joints’wear-prone parts and enhance their durability and reliability through improved design. | Li Zhang Yining Fang Guanghan Bai Junyong Tao | 2023 | Chinese Journal of Mechanical Engineering2023，36，6： | 0 |
| 11 | Failure analysis of unmanned autonomous swarm considering cascading effects显示文摘In this paper, we focus on the failure analysis of unmanned autonomous swarm(UAS) considering cascading effects. A framework of failure analysis for UAS is proposed.Guided by the framework, the failure analysis of UAS with crash fault agents is performed. Resilience is used to analyze the processes of cascading failure and self-repair of UAS. Through simulation studies, we reveal the pivotal relationship between resilience, the swarm size, and the percentage of failed agents.The simulation results show that the swarm size does not affect the cascading failure process but has much influence on the process of self-repair and the final performance of the swarm.The results also reveal a tipping point exists in the swarm. Meanwhile, we get a counter-intuitive result that larger-scale UAS loses more resilience in the case of a small percentage of failed individuals, suggesting that the increasing swarm size does not necessarily lead to high resilience. It is also found that the temporal degree failure strategy performs much more harmfully to the resilience of swarm systems than the random failure. Our work can provide new insights into the mechanisms of swarm collapse, help build more robust UAS, and develop more efficient failure or protection strategies. | XU Bei BAI Guanghan ZHANG Yun’an FANG Yining TAO Junyong | 2022 | Journal of Systems Engineering and Electronics2022，33，3： | 0 |
| 12 | A survey of cloud network fault diagnostic systems and tool显示文摘Recently, cloud computing has become a vital part that supports people’s normal lives and production.However, accompanied by the increasing complexity of the cloud network, failures constantly keep coming up and cause huge economic losses. Thus, to guarantee the cloud network performance and prevent execrable effects caused by failures, cloud network diagnostics has become of great interest for cloud service providers. Due to the characteristics of cloud network(e.g., virtualization and multi-tenancy), transplanting traditional network diagnostic tools to the cloud network face several difficulties. Additionally, many existing tools cannot solve problems in the cloud network. In this paper, we summarize and classify the state-of-the-art technologies of cloud diagnostics which can be used in the production cloud network according to their features. Moreover, we analyze the differences between cloud network diagnostics and traditional network diagnostics based on the characteristics of the cloud network. Considering the operation requirements of the cloud network, we propose the points that should be cared about when designing a cloud network diagnostic tool. Also, we discuss the challenges that cloud network diagnostics will face in future development. | Yining QI Chongrong FANG Haoyu LIU Daxiang KANG Biao LYU Peng CHENG Jiming CHEN | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，8： | 0 |
