| 1 | Dispatch coordination between high-speed and conventional rail systems显示文摘Cross-line trains,as a link between high-speed and conventional rail networks,will increase the complexity of transport organization and lead to significant challenges in dispatch coordination between the two systems.Based on the characteristics of high-speed transport organization,this paper deals with the necessity of dispatch coordination between high-speed and conventional lines from the following two perspectives:the operation of cross-line trains and work coordination in connection stations.An adjustment model for the operation of high-speed trains,taking cross-line trains into account,is established.Finally,the dispatch system is described in terms of construction and process.Methods for organizing dispatch are proposed,and the processes of coordination adjustment under normal and unexpected situations are analyzed.The discussion in this paper may serve as a theoretical basis for the development of high-speed rail dispatch systems. | Qiyuan PENG Chao WEN | 2011 | Journal of Modern Transportation2011，19，1： | 6 |
| 2 | High-Speed Railway Train Timetable Conflict Prediction Based on Fuzzy Temporal Knowledge Reasoning显示文摘近年来,高速铁路各项技术不断发展,列车运行速度从300 km·h^(–1)提高到400 km·h^(–1)。本文介绍了由韩国研究者开发和论证的技术,即400 km·h^(–1)级集电性能评估方法。此外,本文还详细解释了基于视频图像的监测技术,其不需要直接接触供电系统的任何部件,这项技术被应用于检测以时速400 km运行的高铁上架空接触网组件的稳定性。与常规使用激光传感器或者线相机(line camera)来监控架空接触网的系统不同,开发的新型系统通过视频数据来测量其处于活动状态的参数。根据在商业线路上实地测量的结果,这种系统能有效地测量架空接触网的各项参数。 | He Zhuang Liping Feng Chao Wen Qiyuan peng Qizhi Tang | 2016 | Engineering2016，2，3： | 4 |
| 3 | Toll-like receptor 9 defciency induces osteoclastic bone loss via gut microbiota-associated systemic chronic inflammation显示文摘Toll-like receptors(TLRs)play pivotal roles in inflammation and provide important links between the immune and skeletal systems.Although the activation of TLRs may affect osteoclast differentiation and bone metabolism,whether and how TLRs are required for normal bone remodeling remains to be fully explored.In the current study,we show for the first time that TLR9^(-/-)mice exhibit a low bone mass and low-grade systemic chronic inflammation,which is characterized by the expansion of CD4^(+)T cells and increased levels of inflammatory cytokines,including TNFα,RANKL,and IL1β.The increased levels of these cytokines significantly promote osteoclastogenesis and induce bone loss.Importantly,TLR9 deletion alters the gut microbiota,and this dysbiosis is the basis of the systemic inflammation and bone loss observed in TLR9^(-/-)mice.Furthermore,through single-cell RNA sequencing,we identified myeloid-biased hematopoiesis in the bone marrow of TLR9^(-/-)mice and determined that the increase in myelopoiesis,likely caused by the adaptation of hematopoietic stem cells to systemic inflammation,also contributes to inflammation-induced osteoclastogenesis and subsequent bone loss in TLR9^(-/-)mice.Thus,our study provides novel evidence that TLR9 signaling connects the gut microbiota,immune system,and bone and is critical in maintaining the homeostasis of inflammation,hematopoiesis,and bone metabolism under normal conditions. | Peng Ding Qiyuan Tan Zhanying Wei Qiyu Chen Chun Wang Luyue Qi Li Wen Changqing Zhang Chen Yao | 2022 | Bone Research2022，10，3： | 2 |

| 8 | Clinical practice guideline for body composition assessment based on upper abdominal magnetic resonance images annotated using artificial intelligence显示文摘Introduction Upper abdominal magnetic resonance(MR)imaging is appropriate for body composition analysis.111 Especially for individuals with obesity,it is of great value to quantify the hepatic proton density fat fraction(PDFF)and the amount of abdominal adipose tissue during clinical evaluation and for research on obesity-related risks.Analytical results may be used to determine the optimal choice of surgical procedure and evaluate treatment outcomes.Multiple artificial intelligence(Al)algorithms and systems have been developed for the automated measurement of body composition.The basis of Al development and application is to have uniform standards for clinical data acquisition and management.The uneven quality ofMR images is one ofthe major obstacles to Al system development and analytical results.A standardized process of MR scanning and clinical data management is urgently needed. | Han Lv Mengyi Li Zhenchang Wang Dawei Yang Hui Xu Juan Li Yang Liu Di Cao Yawen Liu Xinru Wu He Jin Peng Zhang Liqin Zhao Rixing Bai Yunlong Yue Bin Li Nengwei Zhang Mingzhu Zou Jinghai Song Weibin Yu Pin Zhang Weijun Tang Qiyuan Yao Liheng Liu Hui Yang Zhenghan Yang Zhongtao Zhang National Clinical Research Center for Digestive Diseases in Beijing Friendship Hospital,Capital Medical University Beijing Quality Control and Improvement Center of Medical Imaging National Health Commission Capacity Building and Continuing Education Center,Chinese College of Metabolic and Bariatric Surgeons Beijing Quality Control and Improvement Center of Metabolic and Bariatric Surgery | 2022 | Chinese Medical Journal2022，，6： | 1 |

| 10 | Effects of heterogeneous reaction with NO_(2) on ice nucleation activities of feldspar and Arizona Test Dust显示文摘Mineral dust is an important type of ice nucleating particles in the troposphere;however,the effects of heterogeneous reactions on ice nucleation(IN)activities of mineral dust remain to be elucidated.A droplet-freezing apparatus(Guangzhou Institute of Geochemistry Ice Nucleation Apparatus,GIGINA)was developed in thiswork to measure IN activities of atmospheric particles in the immersion freezingmode,and its performancewas validated by a series of experimental characterizations.This apparatus was then employed to measure IN activities of feldspar and Arizona Test Dust(ATD)particles before and after heterogeneous reaction with NO_(2)(10±0.5 ppmv)at 40%relative humidity.The surface coverage of nitrate,θ(NO_(3)^(−)),increased to 3.1±0.2 for feldspar after reaction with NO_(2) for 6 hr,and meanwhile the active site density per unit surface area(ns)at-20℃ was reduced from 92±5 to<1.0 cm^(−2) by about two orders of magnitude;however,no changes in nitrate content or IN activities were observed for further increase in reaction time(up to 24 hr).Both nitrate content and IN activities changed continuously with reaction time(up to 24 hr)for ATD particles;after reaction with NO_(2) for 24 hr,θ(NO_(3)^(−))increased to 1.4±0.1 and ns at-20℃ was reduced from 20±4 to 9.7±1.9 cm^(−2) by a factor of∼2.Our work suggests that heterogeneous reaction with NO_(2),an abundant reactive nitrogen species in the troposphere,may significantly reduce IN activities of mineral dust in the immersion freezing mode. | Lanxiadi Chen Chao Peng Jingchuan Chen Jie Chen Wenjun Gu Xiaohong Jia Zhijun Wu Qiyuan Wang Mingjin Tang | 2023 | Journal of Environmental Sciences2023，，5： | 0 |
| 11 | Ethylene thiourea exposure induces neurobehavioral toxicity in zebrafish by disrupting axon growth and neuromuscular junctions显示文摘Ethylene thiourea(ETU)converted from ethylene bisdithiocarbamate(EBDC)fungicides has aroused great concern because of its prevalence and harmful effects.Although ETU-induced neurotoxicity has been reported,the potential mechanisms remain unclear.This study provided insights into its neurotoxic effects at environmentally relevant concentrations in zebrafish.Our findings showed that embryonic exposure to ETU decreased the hatch rate and delayed somite development.Furthermore,ETU treatment significantly reduced the dark velocity in the locomotion assay.The upregulated tendency of the mitogen-activated protein kinases(MAPK)pathway(mknk1,atf4,mapkapk3)screened by transcriptome analysis implied motor neuron degeneration,which was validated by subsequent morphological observation,as axon length and branches were truncated in the 62.5μg/L ETU group.However,although the rescue experiment with a p38 MAPK inhibitor(SB203580)successfully ameliorated axon degeneration,it failed to reverse the locomotion behaviors.Further exploration of transcriptome data revealed the varied expression of presynaptic scaffold protein-related genes(pcloa,pclob,bsna),whose downregulation might impair the neuromuscular junction(NMJ).Therefore,we reasonably suspected that ETU-induced neurobehavioral deficits might result from the combined effects of the MAPK pathway and presynaptic proteins.Considering this,we highlighted the necessity to take precautions and early interventions for susceptible ETU-exposed populations. | Jingming Wang Zhiquan Yu Yongfeng Wang Yuanyao Chen Lin Xiao Yanjun Zong Qiyuan Feng Lianqi Peng Huiping Zhang Chunyan Liu | 2024 | Journal of Environmental Sciences2024，，3： | 0 |
| 12 | Statistical delay distribution analysis on high-speed railway trains显示文摘The focus of this study is to explore the statis-tical distribution models of high-speed railway (HSR) train delays. Based on actual HSR operational data, the delay causes and their classification, delay frequency, number of affected trains, and space–time delay distributions are discussed. Eleven types of delay events are classified, and a detailed analysis of delay distribution for each classifica-tion is presented. Models of delay probability delay prob-ability distribution for each cause are proposed. Different distribution functions, including the lognormal, exponen-tial, gamma, uniform, logistic, and normal distribution, were selected to estimate and model delay patterns. The most appropriate distribution, which can approximate the delay duration corresponding to each cause, is derived. Subsequently, the Kolmogorov–Smirnov (K–S) test was used to test the goodness of fit of different train delay distribution models and the associated parameter values. The test results show that the distribution of the test data is consistent with that of the selected models. The fitting distribution models show the execution effect of the timetable and help in finding out the potential conflicts in real-time train operations. | Yuxiang Yang Ping Huang Qiyuan Peng Jie LI Chao Wen | 2019 | Journal of Modern Transportation2019，27，3： | 0 |
| 13 | CsBZIP40 confers resistance against citrus bacterial canker by repressing CsWRKY43-CsPrx53/CsSOD13 cascade mediated ROS scavenging显示文摘As the bacterial etiologic agent causing citrus bacterial canker(CBC),Xanthomonas citri subsp.citri(Xcc)seriously impacts citrus plantation and fruit production globally.In an earlier study,we demonstrated that CsBZIP40 can positively impact CBC resistance in the sweet orange(Citrus sinensis).However,the mechanistic basis for the protective benefits conferred by CsBZIP40 is yet to be delineated.Here,we show that CsBZIP40 positively regulates CBC resistance and reactive oxygen species(ROS)homeostasis in transgenic sweet orange overexpressing CsBZIP40.CsBZIP40 directly binds to the TGA-box of the CsWRKY43 promoter to repress its transcriptional activity.CsWRKY43 overexpression induces CBC susceptibility in transgenic sweet oranges.In contrast,its inhibition produces strong resistance to CBC.CsWRKY43 directly binds to the W-boxes of the CsPrx53 and CsSOD13 promoters to positively regulate the activities of these antioxidant enzymes,resulting in the negative regulation of ROS homeostasis and CBC resistance in sweet orange plants.CsPrx53/CsSOD13 knockdown enhances ROS accumulation and CBC resistance.Overall,our results outline a regulatory pathway through which CsBZIP40 transcriptionally represses CsWRKY43-CsPrx53/CsSOD13 cascade-mediated ROS scavenging in a manner conducive to CBC resistance.These mechanisms underscore the potential importance of CsBZIP40,CsWRKY43,CsPrx53,and CsSOD13,providing promising strategies for the prevention of CBC. | Qiang Li Xiujuan Qin Miao Zhang Qiyuan Yu Ruirui Jia Jie Fan Xin Huang Jia Fu Chenxi Zhang Baohang Xian Wen Yang Qin Long Aihong Peng Lixiao Yao Shanchun Chen Yongrui He | 2023 | Horticulture Research2023，10，8： | 0 |

| 16 | Biodegradation of tetrabromobisphenol A in the sewage sludge process显示文摘Anaerobic sewage sludge capable of rapidly degrading tetrabromobisphenol A(TBBPA) was successfully acclimated in an anaerobic reactor over 280 days. During the period from 0 to 280 days, the TBBPA degradation rate(DR), utilization of glucose, and VSS were monitored continuously. After 280 days of acclimation, the TBBPA DR of active sludge reached 96.0% after 20 days of treatment in batch experiments. Based on scanning electron microscopy(SEM) observations and denaturing gradient gel electrophoresis(DGGE) determinations,the diversity of the microorganisms after 0 and 280 days in the acclimated anaerobic sewage sludge was compared. Furthermore, eleven metabolites, including 2-bromophenol,3-bromophenol, 2,4-dibromophenol, 2,6-dibromophenol, tribromophenol and bisphenol A,were identified by gas chromatography–mass spectrometry(GC–MS). Moreover, the six primary intermediary metabolites were also well-degraded by the acclimated anaerobic sewage sludge to varying degrees. Among the six target metabolites, tribromophenol was the most preferred substrate for biodegradation via debromination. These metabolites degraded more rapidly than monobromide and bisphenol A. The biodegradation data of the intermediary metabolites exhibited a good fit to a pseudo-first-order model.Finally, based on the metabolites, metabolic pathways were proposed. In conclusion, the acclimated microbial consortia degraded TBBPA and its metabolites well under anaerobic conditions. | Xingxing Peng Zhangna Wang Dongyang Wei Qiyuan Huang Xiaoshan Jia | 2017 | Journal of Environmental Sciences2017，29，11： | 0 |
| 17 | Dynamic train dwell time forecasting:a hybrid approach to address the influence of passenger flow fluctuations显示文摘Train timetables and operations are defined by the train running time in sections,dwell time at stations,and headways between trains.Accurate estimation of these factors is essential to decision-making for train delay reduction,train dispatching,and station capacity estimation.In the present study,we aim to propose a train dwell time model based on an averaging mechanism and dynamic updating to address the challenges in the train dwell time prediction problem(e.g.,dynamics over time,heavy-tailed distribution of data,and spatiotemporal relationships of factors)for real-time train dispatching.The averaging mechanism in the present study is based on multiple state-of-the-art base predictors,enabling the proposed model to integrate the advantages of the base predictors in addressing the challenges in terms of data attributes and data distributions.Then,considering the influence of passenger flow on train dwell time,we use a dynamic updating method based on exponential smoothing to improve the performance of the proposed method by considering the real-time passenger amount fluctuations(e.g.,passenger soars in peak hours or passenger plunges during regular periods).We conduct experiments with the train operation data and passenger flow data from the Chinese high-speed railway line.The results show that due to the advantages over the base predictors,the averaging mechanism can more accurately predict the dwell time at stations than its counterparts for different prediction horizons regarding predictive errors and variances.Further,the experimental results show that dynamic smoothing can significantly improve the accuracy of the proposed model during passenger amount changes,i.e.,15.4%and 15.5%corresponding to the mean absolute error and root mean square error,respectively.Based on the proposed predictor,a feature importance analysis shows that the planned dwell time and arrival delay are the two most important factors to dwell time.However,planned time has positive influences,whereas arrival delay has negative influences. | Zishuai Pang Liwen Wang Shengjie Wang Li Li Qiyuan Peng | 2023 | Railway Engineering Science2023，31，4： | 0 |

| 19 | Excitation energy distribution between two photosystems in Porphyra yezoensis and its significance in photosynthesis evolution显示文摘Comparative investigation on energy distribution between two photosystems were carried out in the sporo-phytes and gametophytes of Porphyra yezoensis. By performing 77 K fluorescence spectra, we suggested that there probably existed a pathway for energy transfer from PS II to PS I to redistribute the absorbed energy in gametophytes, while no such a way or at minor level in sporophytes. Electron transfer inhibitor DCMU blocked the energy transfer from PS II to PS I in gametophytes, but no obvious effects on sporophytes. These indicated that excitation energy distribution between two photosystems in gametophytes was more cooperative than that in sporophytes. These data in ontogenesis reflected the evolution process of photosynthetic organisms and supported the hypothesis of independent evolution of each photosystem. | PAN Jie SHI Dingji CHEN Jianxin PENG Guohong ZENG Chengkui ZHANG Qiyuan | 2001 | Chinese Science Bulletin2001，46，1： | 0 |
