1滇西哀牢山构造带:结构与演化显示文摘哀牢山构造带是藏东(东南亚)地区的一条重要线性构造,它分隔了扬子—华南地块与印支地块,并保存了多阶段复杂大地构造演化的记录。哀牢山构造带内由东向西依次发育了晚太古代—新元古代深变质岩系、新生代构造-岩浆活动带(剪切带)、金平—沱江晚二叠—早三叠世裂谷带残余和哀牢山早石炭世—早三叠世混杂岩带。具有不同特点的地质单元间被以新生代为主发育的断裂构造所间隔;而不同时期异地就位或混合岩化成因的花岗质岩石在构造带中普遍存在。哀牢山构造带在不同地质历史阶段具有多重大地构造属性,总体上经历了3个重要大地构造演化阶段:前特提斯演化、特提斯演化和新生代陆内演化阶段。前特提斯演化时期,主体部分(尤其是其东部带)具有亲扬子地块的属性,保留了自晚太古代到新元古代地壳演化的记录。一直到早古生代时期,哀牢山构造带的大地构造属性与扬子—华南地区依然具有密切的亲缘关系。自晚古生代—早中生代时期古特提斯洋打开之后,该带与华南-扬子板块之间分化成2个属性不同的构造域,始于早石炭世打开的哀牢山洋与始于早二叠世打开的金平—沱江洋依次消亡。特提斯洋的闭合,一方面形成了古哀牢山造山带,同时使得扬子—华南地块与印支地块回复到一个统一的陆内环境中;印度—欧亚板块之间的交互作用,对这一地区有着深刻的影响,相继形成了早新生代哀牢山造山带、晚渐新世—早中新世造山后区域性伸展与高钾碱性岩浆活动性和晚渐新世—早中新世印支地块的大规模南东向逃逸、哀牢山大型左行走滑剪切作用及伴生的钙碱性岩浆活动性。刘俊来 唐渊 宋志杰 Tran My Dung 翟云峰 吴文彬 陈文 2011吉林大学学报(地球科学版)2011,41,5:65
2一种中高速区转矩优化的异步电机直接转矩控制算法显示文摘提出一种在异步电机基速内转矩性能优化的直接转矩控制(direct torque control,DTC)算法。该算法在中高速段采用连续定子磁链轨迹切换技术实现了各段定子磁链轨迹平滑切换。随着电机转子速度的升高,定子磁链轨迹依次从圆形、多边形及六边形连续与平滑地切换,算法具有电机转矩脉动小,电机转矩平稳等特点;在高速区段,给出一种非零电压矢量提前注入的控制方案,实现了减小转矩向下脉动,因此有效提高了转矩平均值与转矩平稳性。该DTC算法仅需在传统DTC结构中增加调节定子磁链和调节电压矢量作用时刻算法,既保留了传统DTC算法快速动态响应,以及对电机转子参数不敏感等特征,又确保控制系统较低的计算量要求。理论分析和实验结果都证明了该DTC算法的有效性和可行性。范文进 郑琼林 杨中平 林飞 宋文胜 DO Viet Dung 2016中国电机工程学报2016,36,1:19

5Studies on sustainable features of vernacular architecture in different regions across the world:A comprehensive synthesis and evaluation显示文摘Due to the increasing pressure brought by recent global environmental problems,building designers are embracing regionalism and the knowledge of traditional structures,arguing that these structures are energy efficient and highly sustainable.We observe clear evidence of the increasing interest in vernacular architecture among the research community.This study therefore aims to clarify the contents and issues raised in the studies on vernacular architecture and the knowledge and recommendations that can be derived from them.A database of the research is established by collecting many studies from primary sources.Obtained data is carefully refined and categorized into a table where synthesized information is introduced.The results of this study show an uneven geographic and climatic distribution of the studies;the trend in selecting research objectives and research objects;the choice of research methods with a clear shift towards quantitative research methods,and the generic findings from the database of the research.These results can support diverse inquiries about vernacular architecture across the world and be used as a resource or an orientation to support numerous subsequent studies.Anh Tuan Nguyen Nguyen Song Ha Truong David Rockwood Anh Dung Tran Le 2019Frontiers of Architectural Research2019,8,4:6
6基于刨煤机单刨刀截割试验的截割阻力模型研究显示文摘根据刨煤机刨刀截割煤岩阻力谱以及截割机理,辨识出刨头破碎煤岩的所受截割阻力,提出了基于单刨刀截割阻力、刨刀截割规律及运行参数来确定刨头瞬时截割阻力方法,建立刨头截割阻力试验-理论综合模型,给出了截割阻力模型算法。结果表明:当煤岩阻抗为225 N/cm、崩落角为30°、刨刀数量为14把时,刨头上的刨削阻力达到最大96.86 k N,变差系数达到最小0.509 53,载荷波动较小,有利于刨头刨削煤体,理论分析与试验结果基本吻合,截割阻力的特征和量值均有很好的复合度,单刨刀截割试验可反映出煤岩破碎的内在规律。刘芮葭 Chu Viet Dung Nguyen Viet Tuyen 2016煤炭科学技术2016,44,6:6

8Complex Network Analysis of the Robustness of the Hanoi, Vietnam Bus Network显示文摘Many complex networks exist to facilitate the transport of material or information. In this capacity, the authors are often concerned with the continued flow of material or information when a fraction of the links in the complex network is disrupted. In other words, the authors are interested in the robustness of the complex network. In this paper, the authors survey measures of robustness like the average path length, the average clustering coefficient, the global efficiency, the size of largest cluster and use these to analyze the robustness of the bus network in Hanoi, Vietnam. The authors find that the bus network is robust against random failure but sensitive to targeted attack, in agreement with its scale-free character. By examining sharp drops in the average path length within the largest cluster of the Hanoi bus network under successive targeted attack, the authors identify five nodes whose loss lead to the fragmentation of the network into five or six disconnected clusters. These isolated clusters represent geographically the Central, Western, Southern, and Northwestern districts of Hanoi. Special considerations must therefore be given to these five nodes when planners wish to expand the bus network, or make it more robust.TRAN Vu Hieu CHEONG Siew Ann BUI Ngoc Dung 2019Journal of Systems Science & Complexity2019,32,5:4
9越南Song Da带前新生代构造属性及构造背景分析显示文摘通过越南西北部Song Da带地层、构造、变质岩和岩浆岩的野外考察及补充填图,依据岩石组合特征和区域不整合,将Song Da带前新生代地层划分为前震旦纪结晶基底、寒武系-上三叠统下部及上三叠统上部-白垩系3个构造层。在对各构造层构造属性分析的基础上,与扬子-华南板块前新生代地层进行区域对比,结果显示,Song Da带前新生代各构造层与扬子-华南板块具有相似性,表明Song Da带属于扬子-华南板块。此外,对研究区各构造层形成的构造背景进行分析,认为它们分别是在Columbia超大陆的形成和Rodinia超大陆的裂解、稳定地台盖层的沉积、古特提斯洋关闭以及古太平洋板块向欧亚大陆边缘俯冲的背景下形成的。同时认为,Song Da带向海域的延伸部分——莺歌海盆地基底与Song Da带具有相同的前新生代基底构造层、构造属性和构造背景。岳军培 孙晓猛 HIEU Pham Trung 王璞珺 DUNG Le Tien 郎元强 杜继宇 2013大地构造与成矿学2013,37,4:4
10异步电机牵引特性的仿真研究显示文摘按照异步牵引电机特性,建立起直接转矩控制系统的仿真模型。在启动时,逆变器按脉宽调制方式进行控制,当电机输出功率达到额定值时,进入方波控制区;为有效地抑制系统在启动初始过程中产生很大电流冲击,采用启动限流措施,防止定子磁链发生畸变和开关器件损坏。仿真模拟了异步牵引电机在运行过程中牵引和制动工况,Matlab/Simulink仿真结果表明系统具有良好的稳态性能和动态性能,满足机车运行的要求。仿真结果验证了控制方法的有效性和正确性。Pham Van Tien 冯晓云 ■o Viet Dung 葛兴来 2009电气传动2009,39,5:4
11越南西北部大象山超高温变质岩的发现及其区域构造意义显示文摘越南西北部大象山群孔兹岩系中发育一套含刚玉+尖晶石+石榴石+夕线石组合的富铝岩石块体,它们呈透镜状包体形式赋存于孔兹岩系内。岩石中刚玉+尖晶石+石榴石+夕线石组合的发育指示岩石经历了超高温变质作用的改造。其中尖晶石和石英的共生组合表明了变质温度高于900℃,而利用岩石退变质矿物组合中的黑云母-石榴石温度计,黑云母-斜长石-石榴石-石英组合温度-压力计估算的变质温度压力条件分别为879~917℃、0.90~0.94GPa。岩石中的早期刚玉+夕线石的组合的存在说明岩石变质作用已经从高角闪岩相进入到了麻粒岩相;而峰期变质矿物组合尖晶石+石英的出现,指示了变质温度高于900℃的超高温变质作用。另一方面,退变质过程中钛铁矿的发育表明岩石经历了快速抬升降压的过程。变质作用的P-T轨迹分析揭示出岩石经历了早期同步升温增压后的快速增温达到峰期条件,后经历快速等温减压过程。这种温压条件的变化与板块会聚过程中由于俯冲板片的断离而使软流圈上涌造成热异常的温压条件变化基本一致。通过对超高温变质岩石进行锆石SIMSU-Pb测年获得的结果大于58Ma,推测这次超高温变质与喜马拉雅运动中印度与欧亚大陆的初期会聚-碰撞作用相关。吴虎峻 刘俊来 TRAN My Dung NGUYEN Quang Luat PHAM Binh 吴文彬 陈文 张招崇 2011岩石学报2011,27,9:4
12Orange G degradation by heterogeneous peroxymonosulfate activation based on magnetic MnFe_(2)O_(4)/α-MnO_(2) hybrid显示文摘Wastewater containing an azo dye Orange G(OG)causes massive environmental pollution,thus it is critical to develop a highly effective,environmental-friendly,and reusable catalyst in peroxymonosulfate(PMS)activation for OG degradation.In this work,we successfully applied a magnetic MnFe_(2)O_(4)/α-MnO_(2) hybrid fabricated by a simple hydrothermal method for OG removal in water.The characteristics of the hybrid were investigated by Xray diffraction,scanning electron microscopy,energy-dispersive X-ray spectroscopy,Fourier transform infrared spectroscopy,Brunauer–Emmett–Teller method,vibrating sample magnetometry,electron paramagnetic resonance,thermogravimetric analysis,and X-ray photoelectron spectroscopy.The effects of operational parameters(i.e.,catalytic system,catalytic dose,solution pH,and temperature)were investigated.The results exhibited that 96.8% of OG degradation was obtained with MnFe_(2)O_(4)/α-MnO2(1:9)/PMS system in 30 min regardless of solution pH changes.Furthermore,the possible reaction mechanism of the coupling system was proposed,and the degradation intermediates of OG were identified by mass spectroscopy.The radical quenching experiments and EPR tests demonstrated that SO_(4)•̶,O_(2)•̶,and 1O2 were the primary reactive oxygen species responsible for the OG degradation.The hybrid also displayed unusual stability with less than 30%loss in the OG removal after four sequential cycles.Overall,magnetic MnFe2O4/α-MnO2 hybrid could be used as a high potential activator of PMS to remove orange G and maybe other dyes from wastewater.Le Thi Thao To Van Nguyen Van Quy Nguyen Ngoc Man Phan Ki Jae Kim Nguyen Nhat Huy Nguyen Trung Dung 2023Journal of Environmental Sciences2023,,2:3
13Malaria:elimination tale from Yunnan Province of China and new challenges for reintroduction显示文摘Background::Eradication of infectious disease is the sanctified public health and sustainable development goal around the world.Main body::Three antimalarial barriers were developed to control imported malarial cases,and an effective surveillance strategy known as the'1-3-7 approach'was developed to eliminate malaria from the Chinese population.From 2011 to 2019,5254 confirmed malaria cases were reported and treated in Yunnan Province,China.Among them,4566 cases were imported from other countries,and 688 cases were indigenous from 2011 to 2016.Since 2017,no new local malarial case has been reported in China.Thus,malaria has been completely eliminated in Yunnan Province.However,malaria is detected in overseas travellers on a regular basis,such as visitors from neighbouring Myanmar.Conclusion::Hence,the strategies should be further strengthened to maintain a robust public health infrastructure for disease surveillance and vector control programs in border areas.Such programs should be supported technically and financially by the government to avert the possibility of a malarial resurgence in Yunnan Province.Heng-Lin Yang Zulqarnain Baloch Jian-Wei Xu Xiao-Dong Sun Zu-Rui Lin Yao-Wu Zhou Xiao-Tao Zhao Quan Lv Shi-Yuan Xu Chun-Li Ding Qi-Yan Chen Peng Tian Kai-Xia Dung Xue-Shan Xia Hong-Ning Zhou 2021Infectious Diseases of Poverty2021,10,4:3
14Epithelial cells with hepatobiliary phenotype:Is it another stem cell candidate for healthy adult human liver?显示文摘AIM:To investigate the presence and role of liver epithelial cells in the healthy human adult liver.METHODS:Fifteen days after human hepatocyte primary culture,epithelial like cells emerged and started proliferating.Cell colonies were isolated and sub-cultured for more than 160 d under specific culture conditions.Cells were analyzed for each passage using immunofluorescence,flow cytometry and reverse transcription-polymerase chain reaction(RT-PCR).RESULTS:Flow cytometry analysis demonstrated that liver epithelial cells expressed common markers for hepatic and stem cells such as CD90,CD44 and CD29 but were negative for CD34 and CD117.Using immunofluorescence we demonstrated that liver epithelial cells expressed not only immature(α-fetoprotein)but also differentiated hepatocyte(albumin and CK-18)and biliary markers(CK-7 and 19),whereas they were negative for OV-6.RT-PCR analysis confirmed immunofluorescence data and revealed that liver epithelial cells did not express mature hepatocyte markers such as CYP2B6,CYP3A4 and tyrosine amino-transferase.Purified liver epithelial cells were transplanted into SCID mice.One month after transplantation,albumin positive cell foci were detected in the recipient mouse parenchyma.CONCLUSION:According to their immature and bipotential phenotype,liver epithelial cells might represent a pool of precursors in the healthy human adult liver other than oval cells.Dung Ngoc Khuu Mustapha Najimi Etienne M Sokal 2007World Journal of Gastroenterology2007,13,10:3
15基于连续型定子磁链轨迹的异步牵引电机低转矩脉动控制算法显示文摘本文提出了一种定子磁链轨迹优化的异步牵引电机基速以内的中高速区直接转矩控制(Direct Torque Control,DTC)算法。所提出DTC算法是从以改善转矩脉动角度出发,牵引电机在基速以内的中高速度运行阶段时,随着转速的增加,通过实现定子磁链轨迹从圆形-多边形-六边形的连续切换,获得转矩脉动小与平稳,磁链轨迹平滑、开关频率利用率以及谐波消除能力等的提高。该DTC算法仅需在传统DTC基础结构上仅增加定子磁链调节算法即可,因此它的主要优点是算法简单性,并保留了传统DTC算法快速动态响应,控制电路不复杂,对电机参数依赖性低等特征。理论分析和实验结果都证明了该连续型磁链轨迹的DTC算法的有效性和可行性。范文进-Pham Van Tien 郑琼林 杨中平 林飞 宋文胜 Do Viet Dung 2015电工技术学报2015,30,12:3
