| 2 | Development and experimental validation of a novel hybrid powertrain with dual planetary gear sets for transit bus applications显示文摘Given that energy conservation and environmental protection are two important goals for the automotive industry, the application of a hybrid electric powertrain can improve vehicle energy efficiency while decreasing fuel consumption and engine emissions. Planetary gear-based power-split hybrid powertrains have become widely used in passenger vehicles, but remain rarely employed on transit buses. This study proposes a novel hybrid powertrain based on two planetary gear sets(CHS) and presents its operating principles along with development of a control strategy for the powertrain. The CHS hybrid powertrain operates in electric mode when the driving power demand is low, and changes to a hybrid electric mode according to the power-split principle of the planetary gear set. To validate the feasibility of the designed CHS hybrid powertrain, a prototype transit bus equipped with the designed hybrid powertrain system was built, and the operating characteristics of the system were analyzed through a performance test conducted on a chassis dynamometer. Compared with a conventional powertrain, the CHS hybrid powertrain can reduce fuel consumption by 39%. Thus, the CHS hybrid powertrain is a good solution for heavy-duty applications such as hybrid transit buses because of its simple structure and excellent fuel efficiency. | QIN KongJian WANG EnHua ZHAO Hang SHI GuangKui WANG RenGuang KONG ZhiGuo WANG Wei | 2015 | Science China(Technological Sciences)2015，58，12： | 5 |
| 3 | Comprehensive Multi-Level Exploration of Buried Active Faults:an Example of the Yinchuan Buried Active Fault显示文摘The paper introduces the steps and methods of multi-approach,multi-level exploration of buried faults in thick Quaternary sediment regions by taking the test exploration of the Yinchuan active fault as example.Based on the comprehensive analyses of previous data,we choose the Xinqushao Village of Xingqing District of Yinchuan City as the test site for the comprehensive exploration.Firstly,we adopted shallow seismic investigation with group intervals of 10m,5m and 1m to gradually trace layer by layer the master fault of the Yinchuan buried fault from a deep depth to a shallow depth where drilling could be used.Then,with composite geological profile drilling,we determined the precise location and dip angle of the fault.The drilling show the buried depth of the upper offset point is 8.3m.Finally,large-scale trenching revealed that the actual buried depth of the upper offset point of the fault is 1.5m from the ground surface and there are paleoearthquake events of 5 stages.Combined with the preliminary result of corresponding sample age,we conclude the Yinchuan buried fault is a mid to late Holocene active fault. | Chai Chizhang Meng Guangkui Du Peng Wang Yin Liu Baojin Shen Weihua LeiQiyun Liao Yuhua Zhao Chengbin Feng Shaoying Zhang Xuehui Xie Xiaofeng | 2007 | Earthquake Research in China2007，21，3： | 1 |
| 4 | Characteristics of Late Quaternary Activity of the Luhuatai Buried Fault Revealed by Drilling显示文摘The Luhuatai fault is one of the important buried tectonics in the Yinchuan basin. Based on the results of shallow seismic exploration, we conducted composite drilling section exploration and dating of the samples from boreholes. Some useful data was obtained, such as the depth of the upper breaking point, the latest activity age, displacement in the late Quaternary, and slip rates, etc. This study shows that the activity is different between the north and south segment along the Luhuatai fault. The north segment is a Holocene fault, while the south segment is a late mid-Pleistocene fault. From north to south along the north segment of Luhuatai fault, the activity has been enhanced, and the faulting is stronger in late Pleistocene than Holocene. | Lei Qiyun Chai Chizhang Du Peng Wang Yin Meng Guangkui | 2012 | Earthquake Research in China2012，26，2： | 1 |

| 6 | Self-assembly of lipids and nanoparticles in aqueous solution:Self-consistent field simulations显示文摘Self-assembled nanostructures of lipids and nanoparticles hold great promise for applications in such fields as nanomedicine.This paper uses the self-consistent field theory to investigate the self-assembly behavior of lipid molecules and nanoparticles with different shapes in an aqueous solution.It is found that the lipid molecules can form monolayered and bilayered nanostructures around the nanoparticles with different shapes(e.g.,triangular,square,hexagonal and octangular). With decreasing the size of nanoparticles or increasing the number of polygon edges,the shape of lipid layers will approach an approximately spherical shape.These findings may help to predict and design novel drug delivery nanocarriers. | Weihua Xie Guangkui Xu Xiqiao Feng | 2012 | Theoretical & Applied Mechanics Letters2012，2，1： | 1 |

| 9 | Study of the Activity and Segmentation of Active Faults Using Measurements of Radon and Mercury Gases显示文摘In this paper,measurements of gaseous radon and gaseous mercury densities were conducted for the first time along the Haiyuan active fault zone,including three longer secondary shear faults from Biangou to Shaokou,faults in the Ganyanchi pull-apart basin,and the Biangou push-up structure as well as the thrust fault at the eastern pediment of Liupanshan Mountain in the terminal compressional area.Then relations between fracture gas densities and faulting activity were analyzed.The results show that there is a distinct corresponding relation between gaseous radon and gaseous mercury densities and faulting activity,when the measurement conditions are basically the same,and it proves that the fault gasmetry method is an effective technique for study the activity and segmentation of active faults. | Meng Guangkui,He Kaiming,Ban Tie,and Jiao DechengSeismological Bureau of the Ningxia Hui Autonomous Region,Yinchuan 750001,China | 1997 | Earthquake Research in China1997，11，3： | 1 |
| 10 | Internal oxidation of hot-rolled ultra-high strength steel and its effect on the surface quality of cold-rolled sheets显示文摘In this study,the scale and internal oxidation of hot-rolled ultra-high strength steel sheets were characterized.It was found that both the formation of the scale and the internal oxidation of Si and Mn depended on the coiling temperature and position of the steel sample on the strip coil.At a relatively high coiling temperature,a large amount of internal oxidation was observed on the samples cut from the middle of the coil.The depth of the internal oxidation zone exceeded 10 μm and a thin iron layer covering the scale was observed in some cases.Pickling and cold-rolling experiments were conducted on selected samples.Scale pickling was found to be greatly delayed by the formation of an iron layer,which frequently resulted in under-pickled defects.In addition,pickling of the entire internal oxidation zone was difficult,except at the grain boundaries,where the degree of internal Si and Mn oxidation was enriched.The surface of the cold-rolled steel sheet was ruined by the remaining oxidation zone in the subsurface of the pickled steel.The internal oxidation of hot-rolled ultra-high strength steel must be precisely controlled to improve the subsequent surface quality of cold-rolled steel. | TANG Wenjie JIN Xinyan HU Guangkui CHEN Guang | 2021 | Baosteel Technical Research2021，15，1： | 1 |

| 14 | Effect of Yishen Qiqiao Fang on dopamine content in serum and cerebrospinal fluid of patients in persistent vegetative statec显示文摘BACKGROUND: It has been demonstrated that the attack of persistent vegetative state is associated with the damaged neuron, which produces dopamine, and nervous pathway, the reduce of dopamine or malfunction of dopamine. OBJECTIVE: To observe the effect of self-made traditional Chinese medicine (TCM) Yishen Qiqiao Fang, which has the functions of supplementing qi and nourishing blood, resolving phlegm by promoting blood circulation, restoring consciousness and inducing resuscitation, on the contents of dopamine in serum and cerebrospinal fluid of patients in persistent vegetative state. DESIGN: An open randomized controlled clinical trial. SETTINGS: Nanjing University of Traditional Chinese Medicine, Nanjing Zijin Hospital. PARTICIPANTS: Thirty-eight inpatients of persistent vegetative state were selected from the Department of Neurology, Nanjing Zijin Hospital from August 2005 to November 2006. The patients were diagnosed according to the diagnostic standards set by the summary of a meeting for specialists in Nanjing. Informed contents were obtained from their relatives. According to the order of admission, the enrolled patients were divided into control group (n =20) and TCM treated group (n =20). METHODS: In the control group, the patients were treated with routine treatments for the symptoms. In the TCM treated group, the patients were treated with Yishen Qiqiao Fang besides the same treatments in the control group. TCM dispensing granules: each bag of mongolian milkvetch root, Chinese angelica and peach seed equaled to 10 g crude drug respectively; each bag of grassleaf sweetflag rhizome and dahurian angelica root equaled to 6 g crude drug respectively; Musk 0.05 g. The daily dosage for adults: 4 bags of mongolian milkvetch root, 2 bags of Chinese angelica, 0.05 g musk, 1 bag of peach seed, 2 bags of grassleaf sweetflag rhizome and 2 bags of dahurian angelica root, which should be given though nasal feeding or gastrostogavage before breakfast and supper every day, the course lasted for 2 months. The contents of dopamine in serum and cerebrospinal fluid were determined with enzyme immunoassay analyzer before and after treatment in both groups. MAIN OUTCOME MEASURES: Contents of dopamine in serum and cerebrospinal fluid before and after treatment in both groups. RESULTS: Totally 38 patients of persistent vegetative state were enrolled, 33 of them were involved in the final analysis of results, and the other 5 missed. The contents of dopamine in serum and cerebrospinal fluid had no obvious differences between the two groups both before and after treatment (P > 0.05). In the control group, the contents of dopamine in serum and cerebrospinal fluid had no obvious differences before and after treatment (P > 0.05). In the TCM treated group, the contents of dopamine in serum and cerebrospinal fluid after treatment were obviously higher than those before treatment (t =2.174, 2.485, P < 0.05). CONCLUSION: Yishen Qiqiao Fang can significantly increase the contents of dopamine in serum and cerebrospinal fluid of patients in persistent vegetative state, which may be one of the mechanisms for ameliorating persistent vegetative state. | Guangkui Feng Tao Liu Zhaoqing Xi Fujun Lin Peidong Wang Lichun Zhang Chunping Wu Hulong Ma Chong Liu | 2007 | Neural Regeneration Research2007，2，7： | 1 |
| 15 | Flexoelectric-effect-based light waveguide liquid crystal display for transparent display显示文摘We report a light waveguide liquid crystal display(LCD) based on the flexoelectric effect. The display consists of two parallel flat substrates with a layer of flexoelectric liquid crystal sandwiched between them. A light-emitting diode(LED) is installed on the edge of the display and the produced light is coupled into the display. When no voltage is applied, the liquid crystal is uniformly aligned and is transparent. The incident light propagates through the display by total internal reflection at the interface between the substrate and air, and no light comes out of the viewing side of the display. The display appears transparent. When a voltage is applied, the liquid crystal is switched to a micrometer-sized polydomain state due to flexoelectric interaction and becomes scattering. The incident light is deflected from the waveguide mode and comes out of the viewing side of the display. We achieved thin-film-transistor active matrix compatible driving voltage by doping liquid crystal dimers with large flexoelectric coefficients. The light waveguide LCD does not use polarizers as in conventional LCDs. It has an ultrahigh transmittance near 90% in the voltage-off state. It is very suitable for transparent display, which can be used for head-up display and augmented reality display. | Yunho Shin Yingfei Jiang Qian Wang Ziyuan Zhou Guangkui Qin Deng-Ke Yang | 2022 | Photonics Research2022，10，2： | 1 |

| 17 | 3D collagen matrices modulate the transcriptional trajectory of bone marrow hematopoietic progenitors into macrophage lineage commitment显示文摘Physical signals provided by the extracellular matrix(ECM)are key microenvironmental parameters for the fate decision of hematopoietic stem and progenitor cells(HSPC)in bone marrow.Insights into cell-ECM interactions are critical for advancing HSC-based tissue engineering.Herein,we employed collagen hydrogels and collagen-alginate hydrogels of defined stiffness to study the behaviors of hematopoietic progenitor cells(HPCs).Three-dimensional(3D)collagen hydrogels with a stiffness of 45 Pa were found to promote HPC maintenance and colony formation of monocyte/macrophage progenitors.Using single-cell RNA sequencing(scRNA-seq),we also characterized the comprehensive transcriptional profiles of cells randomly selected from two-dimensional(2D)and 3D hydrogels.A distinct maturation trajectory from HPCs into macrophages within the 3D microenvironment was revealed by these results.3D-derived macrophages expressed high levels of various cytokines and chemokines,such as Saa3,Cxcl2,Socs3 and Tnf.Furthermore,enhanced communication between 3D-macrophages and other hematopoietic clusters based on ligand-repair interactions was demonstrated through bioinformatic analyses.Our research underlines the regulatory role of matrix-dimensionality in HPC differentiation and therefore probably be applied to the generation of specialized macrophages. | Pan Zhang Linmu Xu Jingsong Gao Guangkui Xu Yanping Song Guang Li Jingjing Ren Yunjie Zhang Cheng Yang Yu Zhang Ruiheng Xie Nu Zhang Hui Yang | 2022 | Bioactive Materials2022，7，4： | 0 |
| 18 | Adaptive compensation for time-varying uncertainties in model-based control of lower-limb exoskeleton systems显示文摘Dear editor,Exoskeletons are widely used in human locomotion assistance and strength augmentation to enhance strength and endurance, wherein strategies based on model-based control are extremely sensitive to errors in the dynamic models. Additionally, the unpredictable human-exoskeleton interaction force can unbalance the pilot. Therefore, learning methods were utilized to improve the accuracy of the dynamic model [1, 2]. The modeling of dynamic model was decoupled based on the direction of interest [3]. | Guangkui SONG Rui HUANG Hong CHENG Jing QIU Shuai FAN | 2021 | Science China(Information Sciences)2021，64，11： | 0 |
