| 1 | Adaptive Backstepping Slide Mode Control of Pneumatic Position Servo System显示文摘With the price decreasing of the pneumatic proportional valve and the high performance micro controller, the simple structure and high tracking performance pneumatic servo system demonstrates more application potential in many fields. However, most existing control methods with high tracking performance need to know the model information and to use pressure sensor. This limits the application of the pneumatic servo system. An adaptive backstepping slide mode control method is proposed for pneumatic position servo system. The proposed method designs adaptive slide mode controller using backstepping design technique. The controller parameter adaptive law is derived from Lyapunov analysis to guarantee the stability of the system. A theorem is testified to show that the state of closed-loop system is uniformly bounded, and the closed-loop system is stable. The advantages of the proposed method include that system dynamic model parameters are not required for the controller design, uncertain parameters bounds are not need, and the bulk and expensive pressure sensor is not needed as well. Experimental results show that the designed controller can achieve better tracking performance, as compared with some existing methods. | REN Haipeng FAN Juntao | 2016 | Chinese Journal of Mechanical Engineering2016，29，5： | 8 |
| 2 | ILF3 is a substrate of SPOP for regulating serine biosynthesis in colorectal cancer显示文摘The Serine-Glycien-One-Carbon(SGOC)pathway is pivotal in multiple anabolic processes.Expression levels of SGOC genes are deregulated under tumoeigenic condltions,suggesting panicipation of oncogenes in deregulating the SGOC biosynthetic pathway.However,the underlying mechanism remains elusive.Here,we identifed that Interleukin enfiarccer-binding factor 3(ILF3)is overexpressed in primary CRC patient specimens and correlates with poor progroosis.ILF3 is critical in regulating the SGOC pathway by directly regulating the mRNA stability of SGOC genes,thereby increasing SGOC genes expression and facilitating tumor growth.Mehhanktic studies showed that the EGF-MIEK-ERK pathway nnediates ILF3 phosphorylation,which hin ders E3 ligase speckle-type POZ protein(SPOP)-mediated poly-ubiquitination and degradation of ILF3.Sign iftca ntly,combination of SGOC inhibitor and the anti-EGFR monoclonal antibody cetuximab can hinder the growth of patient-derived xenografts that sustain high ERK-ILF3 levels.Taken together,deregutation of ILF3 via the EGF-ERK signaling plays an important role in systemic serine metabolic reprogramming and confers a predilection toward CRC development.Our findings indicate that clinical evaluation of SCOC inhibitor is warranted for CRC patients with ILF3 overexpression. | Kai Li Jian-lin Wu Baifu Qin Zongmin Fan Qin Tang Weisi Lu Haipeng Zhang Fan Xing Manqi Meng Shaomin Zou Wenxia Wei Honglei Chen Jian Cai Huaiming Wang Hui Zhang Jiayue Cai Ling Fang Xiqing Bian Chuangqi Chen Ping Lan Bart Ghesquiere Lekun Fang Mong-Hong Lee | 2020 | Cell Research2020，30，2： | 6 |
| 3 | Changes of Extreme Precipitation and its Associated Mechanisms in Northwest China显示文摘Characterized by scarce water resources and fragile ecosystems,Northwest China(NWC)has experienced a climate shift from warm-dry to warm-wet conditions since the 1980s that has garnered extensive concern in recent years.In this study,the variability in extreme precipitation(EP)during 1961-2016 in different climate zones of NWC and the possible mechanisms for this variation are investigated.The results show that the EP trends significantly increased in most of the westerly zone(WZ)and plateau zone(PZ),while the EP trends did not significantly decrease in the monsoon zone(MZ).The start dates of extreme precipitation(SDEP)and end dates of extreme precipitation(EDEP)advanced and were postponed,respectively,in the WZ and PZ,while the opposite occurred in the MZ.Summer atmospheric circulation,water vapor transport,and atmospheric instability over NWC varied greatly with the interdecadal shift in EP before and after 1986.During 1986-2016,upper-level divergence and lower-level convergence occurred in the MZ and PZ,which strengthened ascending flow.In addition,the summer water vapor and atmospheric instability increased in the WZ and PZ.These characteristics created favorable conditions for increased occurrences of EP in the WZ and PZ in summer.Conversely,the upper-level convergence and lower-level divergence in the MZ strengthened descending flow.Decreases in summer water vapor and atmospheric instability occurred in the MZ after 1986.Hence,the environmental conditions in the MZ may have prevented the occurrence and development of EP in summer during 1986-2016. | Shan LU Zeyong HU Haipeng YU Weiwei FAN Chunwei FU Di WU | 2021 | Advances in Atmospheric Sciences2021，38，10： | 4 |
| 4 | Risk stratification in symptomatic intracranial atherosclerotic disease with conventional vascular risk factors and cerebral haemodynamics显示文摘Background and purpose Symptomatic intracranial atherosclerotic stenosis(sICAS)is associated with a considerable risk of recurrent stroke despite contemporarily optimal medical treatment.Severity of luminal stenosis in sICAS and its haemodynamic significance quantified with computational fluid dynamics(CFD)models were associated with the risk of stroke recurrence.We aimed to develop and compare stroke risk prediction nomograms in sICAS,based on vascular risk factors and these metrics.Methods Patients with 50%-99%sICAS confirmed in CT angiography(CTA)were enrolled.Conventional vascular risk factors were collected.Severity of luminal stenosis in sICAS was dichotomised as moderate(50%-69%)and severe(70%-99%).Translesional pressure ratio(PR)and wall shear stress ratio(WSSR)were quantified via CTA-based CFD modelling;the haemodynamic status of sICAS was classified as normal(normal PR&WSSR),intermediate(otherwise)and abnormal(abnormal PR&WSSR).All patients received guideline-recommended medical treatment.We developed and compared performance of nomograms composed of these variables and independent predictors identified in multivariate logistic regression,in predicting the primary outcome,recurrent ischaemic stroke in the same territory(SIT)within 1 year.Results Among 245 sICAS patients,20(8.2%)had SIT.The D2H2A nomogram,incorporating diabetes,dyslipidaemia,haemodynamic status of sICAS,hypertension and age≥50 years,showed good calibration(P for Hosmer-Lemeshow test=0.560)and discrimination(C-statistic 0.73,95%CI 0.60 to 0.85).It also had better performance in risk reclassification and provided larger net benefits in decision curve analysis,compared with nomograms composed of conventional vascular risk factors only,and plus the severity of luminal stenosis in sICAS.Sensitivity analysis in patients with anterior-circulation sICAS showed similar results.Conclusions The D2H2A nomogram,incorporating conventional vascular risk factors and the haemodynamic significance of sICAS as assessed in CFD models,could be a useful tool to stratify sICAS patients for the risk of recurrent stroke under contemporarily optimal medical treatment. | Xuan Tian Hui Fang Linfang Lan Hing Lung Ip Jill Abrigo Haipeng Liu Lina Zheng Florence S Y Fan Sze Ho Ma Bonaventure Ip Bo Song Yuming Xu Jingwei Li Bing Zhang Yun Xu Yannie O Y Soo Vincent Mok Ka Sing Wong Thomas W Leung Xinyi Leng | 2023 | Stroke & Vascular Neurology2023，8，1： | 2 |
| 5 | Lineage tracing reveals the origin of Nestin-positive cells are heterogeneous and rarely from ependymal cells after spinal cord injury显示文摘Nestin is expressed extensively in neural stem/progenitor cells during neural development, but its expression is mainly restricted to the ependymal cells in the adult spinal cord. After spinal cord injury(SCI), Nestin expression is reactivated and Nestinpositive(Nestin;) cells aggregate at the injury site. However, the derivation of Nestin;cells is not clearly defined. Here, we found that Nestin expression was substantially increased in the lesion edge and lesion core after SCI. Using a tamoxifen inducible CreER(T2)-loxP system, we verified that ependymal cells contribute few Nestin;cells either to the lesion core or the lesion edge after SCI. In the lesion edge, GFAP+astrocytes were the main cell type that expressed Nestin;they then formed an astrocyte scar.In the lesion core, Nestin;cells expressed αSMA or Desmin, indicating that they might be derived from pericytes. Our results reveal that Nestin;cells in the lesion core and edge came from various cell types and rarely from ependymal cells after complete transected SCI, which may provide new insights into SCI repair. | Xiaoyu Xue Muya Shu Zhifeng Xiao Yannan Zhao Xing Li Haipeng Zhang Yongheng Fan Xianming Wu Bing Chen Bai Xu Yaming Yang Weiyuan Liu Sumei Liu Jianwu Dai | 2022 | Science China(Life Sciences)2022，65，4： | 2 |
| 6 | 2020 Roadmap on gas-involved photo-and electro-catalysis显示文摘Green reactions not only provide us chemical products without any pollution,but also offer us the viable technology to realize difficult tasks in normal conditions.Photo-,photoelectro-,and electrocatalytic reactions are indeed powerful tools to help us to embrace bright future.Especially,some gas-involved reactions are extremely useful to change our life environments from energy systems to liquid fuels and cost-effective products,such as H2 evolution(H2 production),02 evolution/reduction,CO2 reduction,N2 reduction(or N2 fixation) reactions.We can provide fuel cells clean H2 for electric vehicles from H2 evolution reaction(HER),at the same time,we also need highly efficient 02 reduction reaction(ORR) in fuel cells for improving the reaction kinetics.Moreover,we can get the clean oxidant O2 from water through O2 evolution reaction(OER),and carry out some reactions without posing any pollution to reaction systems.Furthermore,we can translate the greenhouse gas CO2 into useful liquid fuels through CO2 reduction reaction(CRR).Last but not the least,we can get ammonia from N2 reduction reaction(NRR),which can decrease energy input compared to the traditional Hubble process.These reactions,such as HER,ORR,OER,CRR and NRR could be realized through solar-,photoelectro-and electro-assisted ways.For them,the catalysts used play crucial roles in determining the efficiency and kinds of products,so we should consider the efficiency of catalysts.However,the cost,synthetic methods of catalysts should also be considered.Nowadays,significant progress has been achieved,however,many challenges still exist,reaction systems,catalysts underlying mechanisms,and so on.As extremely active fields,we should pay attention to them.Under the background,it has motivated us to contribute with a roadmap on ’GasInvolved Photo-and Electro-Catalysis’. | Yulu Yang Yang Tang Haomin Jiang Yongmei Chen Pingyu Wan Maohong Fan Rongrong Zhang Sana Ullah Lun Pan Ji-Jun Zou Mengmeng Lao Wenping Sun Chao Yang Gengfeng Zheng Qiling Peng Ting Wang Yonglan Luo Xuping Sun Alexander S.Konev Oleg V.Levin Panagiotis Lianos Zhuofeng Hu Zhurui Shen Qinglan Zhao Ying Wang Nadia Todorova Christos Trapalis Matthew V.Sheridan Haipeng Wang Ling Zhang Songmei Sun Wenzhong Wang Jianmin Ma | 2019 | Chinese Chemical Letters2019，30，12： | 1 |

| 8 | Gravitational wave astronomy: the current status显示文摘In the centenary year of Einstein's General Theory of Relativity, this paper reviews the current status of gravitational wave astronomy across a spectrum which stretches from attohertz to kilohertz frequencies. Sect. 1 of this paper reviews the historical development of gravitational wave astronomy from Einstein's first prediction to our current understanding the spectrum. It is shown that detection of signals in the audio frequency spectrum can be expected very soon, and that a north-south pair of next generation detectors would provide large scientific benefits. Sect. 2 reviews the theory of gravitational waves and the principles of detection using laser interferometry. The state of the art Advanced LIGO detectors are then described. These detectors have a high chance of detecting the first events in the near future. Sect. 3 reviews the KAGRA detector currently under development in Japan,which will be the first laser interferometer detector to use cryogenic test masses. Sect. 4 of this paper reviews gravitational wave detection in the nanohertz frequency band using the technique of pulsar timing. Sect. 5 reviews the status of gravitational wave detection in the attohertz frequency band, detectable in the polarisation of the cosmic microwave background, and discusses the prospects for detection of primordial waves from the big bang. The techniques described in sects. 1–5 have already placed significant limits on the strength of gravitational wave sources. Sects. 6 and 7 review ambitious plans for future space based gravitational wave detectors in the millihertz frequency band. Sect. 6 presents a roadmap for development of space based gravitational wave detectors by China while sect. 7 discusses a key enabling technology for space interferometry known as time delay interferometry. | BLAIR David JU Li ZHAO ChunNong WEN LinQing CHU Qi FANG Qi CAI RongGen GAO JiangRui LIN XueChun LIU Dong WU Ling-An ZHU ZongHong REITZE David H.

| 10 | Experts consensus on the procedure of dental operative microscope in endodontics and operative dentistry显示文摘The dental operative microscope has been widely employed in the field of dentistry,particularly in endodontics and operative dentistry,resulting in significant advancements in the effectiveness of root canal therapy,endodontic surgery,and dental restoration.However,the improper use of this microscope continues to be common in clinical settings,primarily due to operators’insufficient understanding and proficiency in both the features and established operating procedures of this equipment.In October 2019,Professor Jingping Liang,Vice Chairman of the Society of Cariology and Endodontology,Chinese Stomatological Association,organized a consensus meeting with Chinese experts in endodontics and operative dentistry.The objective of this meeting was to establish a standard operation procedure for the dental operative microscope.Subsequently,a consensus was reached and officially issued.Over the span of about four years,the content of this consensus has been further developed and improved through practical experience. | Bin Liu Xuedong Zhou Lin Yue Benxiang Hou Qing Yu Bing Fan Xi Wei Lihong Qiu Zhengwei Huang Wenwei Xia Zhe Sun Hanguo Wang Liuyan Meng Bin Peng Chen Zhang Shuli Deng Zhaojie Lu Deqin Yang Tiezhou Hou Qianzhou Jiang Xiaoli Xie Xuejun Liu Jiyao Li Zuhua Wang Haipeng Lyu Ming Xue Jiuyu Ge Yi Du Jin Zhao Jingping Liang | 2023 | International Journal of Oral Science2023，15，3： | 0 |
| 11 | Ultrastable and highly efficient CsPbBr_(3) composites achieved by dual-matrix encapsulation for display devices显示文摘Perovskite nanocrystals(NCs)with high stabilities and excellent optical perfor-mances are crucial for display applications.However,to date,perovskite emitters with both high photoluminescence(PL)quantum yield(PLQY)and high stabili-ties under harsh synergistic humidity–heat–light aging conditions have not been reported.The promising high-temperature solid-state sintering with single oxide matrices cannot ensure high PLQY and synergistic aging stabilities of perovskites.Herein,both the PLQY and overall(thermal,moisture,and photo)stabilities of all-inorganic perovskite(CsPbBr_(3))NCs are improved by dual-matrix encapsula-tion,which is accomplished by in situ crystallization of CsPbBr_(3)@Cs_(4)PbBr_(6)nanocomposites in silica molecular sieve(MS)templates via advanced solid-state synthesis a using precisely controlled molar ratio of precursor components and cooling rates.The Cs_(4)PbBr_(6)matrix effectively passivates the surfaces of CsPbBr_(3)NCs,and the MS matrix insulates CsPbBr_(3)@Cs_(4)PbBr_(6)from the external environ-ment.The resulting CsPbBr_(3)@Cs_(4)PbBr_(6)/MS composites exhibit the highest PLQY(>90%)among those of the solid-state perovskite NCs and significant stabilities against water,heat,and blue light irradiation,maintaining more than 80%of their initial PL intensities after being aged for 1000 h under synergistic high-humidity(85%),high-temperature(85C),and strong blue light irradiation(350 mW cm2)conditions.To the best of our knowledge,these CsPbBr_(3)@Cs_(4)PbBr_(6)/MS composites represent the most stable perovskite emitters under synergistic humidity–heat–light aging conditions.The liquid crystal display backlight module fabricated using these stable composites demonstrates a wide color gamut of 131%of the National Television Standards Committee standard.We speculate that this dual-matrix encapsulation can be used for industrial mass production. | Chao Fan Haipeng Liu Jianwu Zhou Xingliang Dai Haiping He Zhizhen Ye | 2023 | InfoMat2023，5，7： | 0 |

| 13 | Overlapping community‐based particle swarm optimization algorithm for influence maximization in social networks显示文摘Influence maximization,whose aim is to maximise the expected number of influenced nodes by selecting a seed set of k influential nodes from a social network,has many applications such as goods advertising and rumour suppression.Among the existing influence maximization methods,the community‐based ones can achieve a good balance between effectiveness and efficiency.However,this kind of algorithm usually utilise the network community structures by viewing each node as a non‐overlapping node.In fact,many nodes in social networks are overlapping ones,which play more important role in influence spreading.To this end,an overlapping community‐based particle swarm opti-mization algorithm named OCPSO for influence maximization in social networks,which can make full use of overlapping nodes,non‐overlapping nodes,and their interactive information is proposed.Specifically,an overlapping community detection algorithm is used to obtain the information of overlapping community structures,based on which three novel evolutionary strategies,such as initialisation,mutation,and local search are designed in OCPSO for better finding influential nodes.Experimental results in terms of influence spread and running time on nine real‐world social networks demonstrate that the proposed OCPSO is competitive and promising comparing to several state‐of‐the‐arts(e.g.CGA,CMA‐IM,CIM,CDH‐SHRINK,CNCG,and CFIN). | Lei Zhang Yutong Liu Haipeng Yang Fan Cheng Qi Liu Xingyi Zhang | 2023 | CAAI Transactions on Intelligence Technology2023，8，3： | 0 |

| 15 | Assessing the dynamics of human activity intensity and its natural and socioeconomic determinants in Qinghai-Tibet Plateau显示文摘Investigating the spatiotemporal variation of human activity intensity and its determinants is a crucial basis for further revealing the mechanism of human-environment interaction and optimizing the human development mode.In this study,the human activity intensity on the Qinghai-Tibet Plateau(QTP)from 1990 to 2020 was measured based on the quantitative model of land use data and the actual regional background,and the under-lying natural and socioeconomic determinants were investigated using spatial econometric methods.The results demonstrate that(1)the human activity intensity in QTP has increased by 11.96%,and there are differences in different spatial scales;the areas with high human activity intensity are distributed in the Hehuang Valley where Xining City and its surrounding areas are located,as well as the One-River and Two-River Area where Lhasa City and surrounding areas are located.(2)Human activity intensity has significant positive spatial spillover,suggesting that local changes will cause changes in the same direction in adjacent areas.(3)The human activ-ity intensity in QTP is affected by various determinants.Concerning socioeconomic factors,the economic level has no significant impact on the human activity intensity in QTP,which differs from the general regional law.Both urbanization and traffic conditions have a significant positive effect,and the impact intensity continues to increase.Concerning natural factors,topographic relief has a significant positive effect;the impacts of temper-ature and vegetation coverage have changed from insignificant to a significant positive effect;the impacts of precipitation and river network density have not been verified;there is no linear relationship between altitude and human activity intensity in the entire QTP,while it exists in local regions.Finally,this study proposes three policy implications for the realization of a more harmonious human-environment relationship in QTP. | Hanchu Liu Jie Fan Kan Zhou Xin Xu Haipeng Zhang Rui Guo Shaofeng Chen | 2023 | Geography and Sustainability2023，4，4： | 0 |
| 16 | Promotion of liquid-to-solid phase transition of cGAS by Baicalein suppresses lung tumorigenesis显示文摘Dear Editor,Kras and p53 mutation are among the most common gene mutations in lung cancer,which has both the highest incidence and mortality rate among cancers.1 Kras/p53 mutation also causes mitochondrial dysfunction,which has been implicated to promote the inflammation-to-cancer transition.2 We established a lung adenocarcinoma model by using conditional alleles of KrasLSLG12D/p53flox/flox in mice3 to evaluate the effect of Baicalein(5,6,7-trihydroxyflavone),a principal component of Scutellaria baicalensis in traditional Chinese medicine,4 on the initiation and progression of lung cancer.Cre-mediated expression of KrasG12D and deletion of p53 caused obvious tumor lesions in the lung,which were strongly inhibited by the administration of Baicalein(Fig.1a,b and Supplementary Fig.1a,b),indicating that Baicalein is highly potent in inhibiting the progression of primary lung cancer. | Tiansheng Zheng Haipeng Liu Yifan Hong Yajuan Cao Qing Xia Chengge Qin Ming Li Russel J.Reiter Yidong Bai Lihong Fan | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 0 |
| 17 | Automatic segmentation algorithm for high-spatial-resolution remote sensing images based on self-learning super-pixel convolutional network显示文摘Super-pixel algorithms based on convolutional neural networks with fuzzy C-means clustering are widely used for high-spatial-resolution remote sensing images segmentation.However,this model requires the number of clusters to be set manually,resulting in a low automation degree due to the complexity of the iterative clustering process.To address this problem,a segmentation method based on a self-learning super-pixel network(SLSP-Net)and modified automatic fuzzy clustering(MAFC)is proposed.SLSP-Net performs feature extraction,non-iterative clustering,and gradient reconstruction.A lightweight feature embedder is adopted for feature extraction,thus expanding the receiving range and generating multi-scale features.Automatic matching is used for non-iterative clustering,and the overfitting of the network model is overcome by adaptively adjusting the gradient weight parameters,providing a better irregular super-pixel neighborhood structure.An optimized density peak algorithm is adopted for MAFC.Based on the obtained super-pixel image,this maximizes the robust decision-making interval,which enhances the automation of regional clustering.Finally,prior entropy fuzzy C-means clustering is applied to optimize the robust decision-making and obtain the final segmentation result.Experimental results show that the proposed model offers reduced experimental complexity and achieves good performance,realizing not only automatic image segmentation,but also good segmentation results. | Zenan Yang Haipeng Niu Liang Huang Xiaoxuan Wang Liangxin Fan Dongyang Xiao | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
