1Intelligent and connected vehicles: Current status and future perspectives显示文摘Intelligent connected vehicles(ICVs) are believed to change people's life in the near future by making the transportation safer,cleaner and more comfortable. Although many prototypes of ICVs have been developed to prove the concept of autonomous driving and the feasibility of improving traffic efficiency, there still exists a significant gap before achieving mass production of high-level ICVs. The objective of this study is to present an overview of both the state of the art and future perspectives of key technologies that are needed for future ICVs. It is a challenging task to review all related works and predict their future perspectives, especially for such a complex and interdisciplinary area of research. This article is organized to overview the ICV key technologies by answering three questions: what are the milestones in the history of ICVs; what are the electronic components needed for building an ICV platform; and what are the essential algorithms to enable intelligent driving? To answer the first question, the article has reviewed the history and the development milestones of ICVs. For the second question, the recent technology advances in electrical/electronic architecture, sensors, and actuators are presented. For the third question, the article focuses on the algorithms in decision making, as the perception and control algorithm are covered in the development of sensors and actuators. To achieve correct decision-making, there exist two different approaches: the principle-based approach and data-driven approach. The advantages and limitations of both approaches are explained and analyzed. Currently automotive engineers are concerned more with the vehicle platform technology, whereas the academic researchers prefer to focus on theoretical algorithms. However, only by incorporating elements from both worlds can we accelerate the production of high-level ICVs.YANG DianGe JIANG Kun ZHAO Ding YU ChunLei CAO Zhong XIE ShiChao XIAO ZhongYang JIAO XinYu WANG SiJia ZHANG Kai 2018Science China(Technological Sciences)2018,61,10:31
2An atomic force microscopy study of coal nanopore structure显示文摘Coal nanopore structure is an important factor in understanding the storage and migration of absorbed gas in coal. A new method for studying coal nanopore structures is proposed. This idea is based on the nano-level resolution of atomic force microscopy, which can be employed to observe the structural features of coal nanopores clearly, conduct quantitative three-dimensional measurements and obtain structural parameters. Analysis results show that coal nanopores are mainly metamorphic pores and intermolecular pores. The metamorphic pores are commonly rounded and elliptical, increasing quantitatively with the coalification degree. The forms of intermolecular pores change markedly. The average pore size of low-rank coal is bigger than high-rank coal, and the number of intermolecular pores decreases as the coal rank increases. Section analysis effectively characterizes the coal pore microstructure, bearing analysis is a vital approach to measure microporosity, and grain analysis can be employed to study the pore size distribution. Atomic force microscopy is a tool for the in-depth research of coal pore microstructure and the coal-bed methane adsorption mechanism.YAO SuPing JIAO Kun ZHANG Ke HU WenXuan DING Hai LI MiaoChun PEI WenMing 2011Chinese Science Bulletin2011,56,25:30
3Third-order point contact approach for five-axis sculptured surface machining using non-ball-end tools (Ⅰ): Third-order approximation of tool envelope surface显示文摘In this paper, the geometric properties of a pair of line contact surfaces are investigated. Then, based on the observation that the cutter envelope surface contacts with the cutter surface and design surface along the characteristic curve and cutter contact (CC) path, respectively, a mathematical model describing the third-order approximation of the cutter envelope surface according to just one given cutter location (CL) is developed. It is shown that at the CC point both the normal curvature of the normal section of the cutter envelope surface and its derivative with respect to the arc length of the normal section can be determined by those of the cutter surface and design surface. This model characterizes the intrinsic relationship among the cutter surface, cutter envelope surface and design surface in the neighborhood of the CC point, and yields the mathematical foundation for optimally approximating the cutter envelope surface to the design surface by adjusting the cutter location.ZHU LiMin1, DING Han2 & XIONG YouLun2 1 State Key Laboratory of Mechanical System and Vibration, Shanghai Jiao Tong University, Shanghai 200240, China 2 State Key Laboratory of Digital Manufacturing Equipment and Technology, Huazhong University of Science and Technology, Wuhan 430074, China 2010Science China(Technological Sciences)2010,53,7:25
4Global optimization of tool path for five-axis flank milling with a cylindrical cutter显示文摘In this paper, optimum positioning of cylindrical cutter for five-axis flank milling of non-developable ruled surface is addressed from the perspective of surface approximation. Based on the developed interchangeability principle, global optimization of the five-axis tool path is modeled as approximation of the tool envelope surface to the data points on the design surface following the minimum zone criterion recommended by ANSI and ISO standards for tolerance evaluation. By using the signed point-to-surface distance function, tool path plannings for semi-finish and finish millings are formulated as two constrained optimization problems in a unified framework. Based on the second order Taylor approximation of the distance function, a sequential approximation algorithm along with a hierarchical algorithmic structure is developed for the optimization. Numerical examples are presented to confirm the validity of the proposed approach.DING Han1 & ZHU LiMin2 1 State Key Laboratory of Digital Manufacturing Equipment and Technology, Huazhong University of Science and Technology, Wuhan 430074, China 2 School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240, China 2009Science China(Technological Sciences)2009,52,8:23
5Third-order point contact approach for five-axis sculptured surface machining using non-ball-end tools(II): Tool positioning strategy显示文摘Based on the mathematical model describing the third-order approximation of the cutter envelope surface according to one given cutter location(CL),a tool positioning strategy is proposed for efficiently machining free-form surfaces with non-ball-end cutters.The optimal CL is obtained by adjusting the inclination and tilt angles of the cutter until its envelope surface and the design surface have the third-order contact at the cutter contact(CC)point,which results in a wide machining strip.The strategy can handle the constraints of machine joint angle limits,global collision avoidance and tool path smoothness in a nature way,and can be applied to general rotary cutters and complex surfaces.Numerical examples demonstrate that the third-order point contact approach can improve the machining strip width greatly as compared with the recently reported second-order one.ZHU LiMin 1 ,DING Han 2 &XIONG YouLun 2 1State Key Laboratory of Mechanical System and Vibration,Shanghai Jiao Tong University,Shanghai 200240,China 2State Key Laboratory of Digital Manufacturing Equipment and Technology,Huazhong University of Science and Technology,Wuhan 430074, China 2010Science China(Technological Sciences)2010,53,8:23
6Dual-targeting and microenvironment-responsive micelles as a gene delivery system to improve the sensitivity of glioma to radiotherapy显示文摘Dbait is a small double-stranded DNA molecule that has been utilized as a radiosensitizer to enhance the sensitivity of glioma to radiotherapy(RT). However, there is no effective drug delivery system to effectively overcome the blood–brain barrier(BBB). The aim of this study was to develop a gene delivery system by using the BBB and glioma dual-targeting and microenvironment-responsive micelles(ch-Kn(s-s)R8-An) to deliver Dbait into glioma for RT. Angiopep-2 can target the low-density lipoprotein receptor-related protein-1(LRP1) that is overexpressed on brain capillary endothelial cells(BCECs) and glioma cells. In particular, due to upregulated matrix metalloproteinase 2(MMP-2) in the tumor microenvironment, we utilized MMP-2-responsive peptides as the enzymatically degradable linkers to conjugate angiopep-2. The results showed that ch-Kn(s-s)R8-An micelles maintained a reasonable size(80–160 nm) with a moderate distribution and a decreased mean diameter from the cross-linking as well as exhibited low critical micelle concentration(CMC) with positive surface charge, ranging from 15 to40 mV. The ch-K5(s-s)R8-An/pEGFP showed high gene transfection efficiency in vitro, improved uptake in glioma cells and good biocompatibility in vitro and in vivo. In addition, the combination of ch-K5(s-s)R8-An/Dbait with RT significantly inhibited the growth of U251 cells in vitro. Thus, ch-K5(s-s)R8-An/Dbait may prove to be a promising gene delivery system to target glioma and enhance the efficacy of RT on U251 cells.Xiuxiu Jiao Yuan Yu Jianxia Meng Mei He Charles Jian Zhang Wenqian Geng Baoyue Ding Zhuo Wang Xueying Ding 2019Acta Pharmaceutica Sinica B2019,9,2:13
7Resveratrol attenuates bone cancer pain through regulating the expression levels of ASIC3 and activating cell autophagy显示文摘骨头癌症疼痛(BCP ) 是在有恶意的癌症的病人的最普通的疼痛之一。位于 BCP 下面的机制大部分是未知的。我们的以前的研究和增加的证据两个都显示出那个酸察觉到的离子隧道(ASIC3 ) 3 是处于在一些疼痛模型的病理学的疼痛状态的重要蛋白质。我们假设了 ASIC3 的表示变化可能是与 BCP 有关的因素之一。在这研究,我们通过 intrathecally 把老鼠乳腺癌房间(MRMT-1 ) 注入 Sprague-Dawley 雌老鼠的左胫骨建立了 BCP 模型,并且发现 BCP 老鼠在 L4-L6 背面的根中心显示出骨头破坏,增加的机械疼痛敏感和起来调整的 ASIC3 蛋白质表示层次。然后, resveratrol, intraperitoneally 在手术后的白天 21 上被注入 BCP 老鼠, dose-dependently 增加了 BCP 老鼠的爪退却阀值,颠倒了疼痛行为,并且有 BCP 老鼠上的 antinociceptive 效果。在 ASIC3-transfected SH-SY5Y 房间, ASIC3 蛋白质表示层次被 resveratrol 在一个剂量依赖者和时间依赖者举止调整。同时, resveratrol 也在调停 ASIC3 的疼痛老鼠模型有 antinociceptive 效果。而且, resveratrol 也在 ASIC3-transfected SH-SY5Y 房间提高了 AMPK, SIRT1,和 LC3-II 层次的 phosphorylation,显示 resveratrol 能激活在 ASIC3-transfected SH-SY5Y 房间的 AMPK-SIRT1-autophagy 信号小径。在 BCP 老鼠, SIRT1 和 LC3-II 也是下面调整的。这些调查结果在 BCP 状态期间作为一个治疗学的处理为 resveratrol 的使用提供新证据(?作者 2017。代表生物化学和房间生物学的研究所由牛津大学出版社出版了,为生物科学的上海研究所,中国科学院。版权所有。为权限,请发邮件:journals.permissions@oup.com。)Haili Zhu Jieqiong Ding Ji Wu Tingting Liu Jing Liang Qiong Tang Ming Jiao 2017Acta Biochimica et Biophysica Sinica2017,49,11:12
8Clinical Characteristics of Children with Coronavirus Disease 2019 in Hubei, China显示文摘Since December 2019,COVID-19 has occurred unexpectedly and emerged as a health problem worldw ide.Despite the rapidly increasing number of cases in subsequent weeks,the clinical characteristics of pediatric cases are rarely described.A cross-sectional multicenter study was carried out in 10 hospitals across Hubei province.A total of 25 confirmed pediatric cases of COVID-19 were collected.The demographic data,epidemiological history,underlying discascs,clinical mani festations,laboratory and radiological data,treatments,and outcomes were analyzcd.Of 25 hospitalized patients with COVID-19,the boy to girl ratio was 1.27:1.The median age was 3 years.COVID-19 cases in children aged<3 years,3-6 years,and≥6-years patients were 10(40%),6(24%),and 9(36%),respectively.The most common symptoms at onset of ilness were fever(13[52%]),and dry cough(11[44%]).Chest CT images showed essential normal in 8 cases(33.3%),unilateral involvement of lungs in 5 cases(20.8%),and bilateral involvement in 11 cases(45.8%).Clinical diagnoses included upper respiratory tract infection(n=8),mild pneumonia(n=15),and critical cases(n=2).Two critical cases(8%)were given invasive mechanical ventilation,corticosteroids,and immunoglobulin.The symptoms in 24(96%)of 25 patients were alleviated and one patient had been discharged.It was concluded that children were susceptible to COVID-19 like adults,while the clinical presentations and outcomes were more favorable in children.However,children less than 3 years old accounted for majority cases and critical cases lied in this age group,which demanded extra attentions during home caring and hospitalization treatment.Fang ZHENG Chun LIAO Qi-hong FAN Hong-bo CHEN Xue-gong ZHAO Zhong-guo XIE Xi-lin LI Chun-xi CHEN Xiao-xia LU Zhi-sheng LIU Wei LU Chun-bao CHEN Rong JIAO Ai-ming ZHANG Jin-tang WANG Xi-wei DING Yao-guang ZENG Li-ping CHENG Qing-feng HUANG Jiang WU Xi-chang LUO Zhu-jun WANG Yan-yan ZHONG Yan BAI Xiao-yan WU Run-ming JIN 2020Current Medical Science2020,40,2:10
9Aligned Graphene Nanoribbons and Crossbars from Unzipped Carbon Nanotubes显示文摘Aligned graphene nanoribbon (GNR) arrays have been made by unzipping of aligned single-walled and few-walled carbon nanotube (CNT) arrays. Nanotube unzipping was achieved by a polymer-protected Ar plasma etching method, and the resulting nanoribbon array can be transferred onto any chosen substrate. Atomic force microscope (AFM) imaging and Raman mapping on the same CNTs before and after unzipping confirmed that ~80% of CNTs were opened up to form single layer sub-10 nm GNRs. Electrical devices made from the GNRs (after annealing in H2 at high temperature) showed on/off current (Ion/Ioff) ratios up to 103 at room temperature, suggesting the semiconducting nature of the narrow GNRs. Novel GNR-GNR and GNR-CNT crossbars were fabricated by transferring GNR arrays across GNR and CNT arrays, respectively. The production of such ordered graphene nanoribbon architectures may allow for large scale integration of GNRs into nanoelectronics or optoelectronics.Liying Jiao Li Zhang Lei Ding Jie Liu Hongjie Dai 2010Nano Research2010,3,6:9
10CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19.Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen 2020Signal Transduction and Targeted Therapy2020,5,1:9

14Labile Organic Matter Content and Distribution as Affected by Six-year Soil Amendments to Eroded Chinese Mollisols显示文摘Labile organic carbon(LOC)is a fraction of soil organic carbon(SOC)with rapid turnover time and is affected by soil fertilization.This investigation characterized the SOC content,LOC content and LOC distribution in the treatment plots of surface soil erosion at five levels(0-,5-,10-,20-and 30-cm erosion).The soil had received contrasting fertilizer treatments(i.e.,chemical fertilizer or chemical fertilizer+manure)for 6 years.This study demonstrated that both SOC and various LOC fractions contents were higher in the plots with fertilizer+manure than in those with fertilizer alone under the same erosion conditions.The SOC and LOC contents decreased as the erosion depth increased.Light fraction organic carbon,particulate organic carbon,easily oxidizable organic carbon(KMnO4-oxydizable organic carbon),and microbial biomass carbon were 27%–57%,37%–47%,20%–25%,and 29%–33%higher respectively in the fertilizer+manure plots,than in the fertilizer alone plots.Positive correlations(p<0.05)between SOC content and different fractions contents were observed in all plots except the correlation between total SOC content and water-soluble organic carbon content in the different fertilization treatments.Obviously,fertilizer+manure treatments would be conducive to the accumulation of LOC and SOC in the Black soil of Northeast China.SUI Yueyu JIAO Xiaoguang CHEN Wenting LIU Xiaobing ZHANG Xingyi DING Guangwei 2013Chinese Geographical Science2013,23,6:7

17Multicenter Clinical Study for Evaluation of Efficacy and Safety of Transdermal Fentanyl Matrix Patch in Treatment of Moderate to Severe Cancer Pain in 474 Chinese Cancer Patients显示文摘Objective: Although a new matrix formulation fentanyl has been used throughout the world for cancer pain management, few data about its efficacy and clinical outcomes associated with its use in Chinese patients have been obtained. This study aimed to assess the efficacy and safety of the new system in Chinese patients with moderate to severe cancer pain. Methods: A total of 474 patients with moderate to severe cancer pain were enrolled in this study and were treated with the new transdermal fentanyl matrix patch (TDF) up to 2 weeks. All the patients were asked to record pain intensity, side effects, quality of life (QOL), adherence and global satisfaction. The initial dose of fentanyl was 25 ?g/h titrated with opioid or according to National Comprehensive Cancer Network (NCCN) guidelines. Transdermal fentanyl was changed every three days. Results: After 2 weeks. The mean pain intensity of the 459 evaluated patients decreased significantly from 5.63?1.26 to 2.03?1.46 (P<0.0001). The total remission rate was 91.29%, of which moderate remission rate 53.16%, obvious remission rate 25.49% and complete remission rate 12.64%. The rate of adverse events was 33.75%, 18.78% of which were moderate and 3.80% were severe. The most frequent adverse events were constipation and nausea. No fatal events were observed. The quality of life was remarkably improved after the treatment (P<0.0001). Conclusion: The new TDF is effective and safe in treating patients with moderate to severe cancer pain, and can significantly improve the quality of life.Yu-lin Zhu Guo-hong Song Duan-qi Liu Xi Zhang Kui-feng Liu Ai-hua Zang Ying Cheng Guo-chun Cao Jun Liang Xue-zhen Ma Xin Ding Bin Wang Wei-lian Li Zuo-wei Hu Gang Feng Jiang-jin Huang Xiao Zheng Shun-chang Jiao Rong Wu Jun Ren 2011Chinese Journal of Cancer Research2011,23,4:6

19Multiple action sites of ultrasound on Escherichia coli and Staphylococcus aureus显示文摘Ultrasound,is thought to a potential non-thermal sterilization technology in food industry.However,the exact mechanisms underlying microbial inactivation by ultrasound still remain obscure.In this study,the action modes of ultrasound on both Gram-negative and Gram-positive microorganisms were estimated.From colony results,ultrasound acted as an irreversible effect on both Eshcerichia coli and Staphylococcus aureus without sublethal injury.The result in this study also showed that a proportion of bacteria subpopulation suffered from serious damage of intracellular components(e.g.DNA and enzymes)but with intact cell envelopes.We speculated that the inactivated effects of ultrasound on microbes might more than simply completed disruption of cell exteriors.Those microbial cells who had not enter the valid area of ultrasonic cavitation might be injected with free radicals produced by ultrasound and experienced interior injury with intact exterior structure,and others who were in close proximity to the ultrasonic wave field would be immediately and completely disrupted into debris by high power mechanic forces.These findings here try to provide extension for the inactivation mechanisms of ultrasound on microorganisms.Xinyu Liao Jiao Li Yuanjie Suo Shiguo Chen Xingqian Ye Donghong Liu Tian Ding 2018Food Science and Human Wellness2018,7,1:6
20CD147 antibody specifically and effectively inhibits infection and cytokine storm of SARS-CoV-2 and its variants delta,alpha,beta,and gamma显示文摘SARS-CoV-2 mutations contribute to increased viral transmissibility and immune escape,compromising the effectiveness of existing vaccines and neutralizing antibodies.An in-depth investigation on COVID-19 pathogenesis is urgently needed to develop a strategy against SARS-CoV-2 variants.Here,we identified CD147 as a universal receptor for SARS-CoV-2 and its variants.Meanwhile,Meplazeumab,a humanized anti-CD147 antibody,could block cellular entry of SARS-CoV-2 and its variants-alpha,beta,gamma,and delta,with inhibition rates of 68.7,75.7,52.1,52.1,and 62.3%at 60μg/ml,respectively.Furthermore,humanized CD147 transgenic mice were susceptible to SARS-CoV-2 and its two variants,alpha and beta.When infected,these mice developed exudative alveolar pneumonia,featured by immune responses involving alveoli-infiltrated macrophages,neutrophils,and lymphocytes and activation of IL-17 signaling pathway.Mechanistically,we proposed that severe COVID-19-related cytokine storm is induced by a'spike protein-CD147-CyPA signaling axis':Infection of SARS-CoV-2 through CD147 initiated the JAK-STAT pathway,which further induced expression of cyclophilin A(CyPA);CyPA reciprocally bound to CD147 and triggered MAPK pathway.Consequently,the MAPK pathway regulated the expression of cytokines and chemokines,which promoted the development of cytokine storm.Importantly,Meplazumab could effectively inhibit viral entry and inflammation caused by SARS-CoV-2 and its variants.Therefore,our findings provided a new perspective for severe COVID-19-related pathogenesis.Furthermore,the validated universal receptor for SARS-CoV-2 and its variants can be targeted for COVID-19 treatment.Jiejie Geng Liang Chen Yufeng Yuan Ke Wang Youchun Wang Chuan Qin Guizhen Wu Ruo Chen Zheng Zhang Ding Wei Peng Du Jun Zhang Peng Lin Kui Zhang Yongqiang Deng Ke Xu Jiangning Liu Xiuxuan Sun Ting Guo Xu Yang Jiao Wu Jianli Jiang Ling Li Kun Zhang Zhe Wang Jing Zhang Qingguo Yan Hua Zhu Zhaohui Zheng Jinlin Miao Xianghui Fu Fengfan Yang Xiaochun Chen Hao Tang Yang Zhang Ying Shi Yumeng Zhu Zhuo Pei Fei Huo Xue Liang Yatao Wang Qingyi Wang Wen Xie Yirong Li Mingyan Shi Huijie Bian Ping Zhu Zhi-Nan Chen 2021Signal Transduction and Targeted Therapy2021,6,10:6
