| 1 | Molecular phylogeny and biogeography of the highly specialized grade schizothoracine fishes (Teleostei:Cyprinidae) inferred from cytochrome b sequences显示文摘We recovered the phylogenetic relationships among 23 species and subspecies of the highly special-ized grade schizothoracine fishes distributing at 36 geographical sites in the Tibetan Plateau and its surrounding regions by analyzing sequences of cytochrome b genes. Furthermore, we estimated the possible divergent times among lineages based on a historical geological isolation event in the Tibetan Plateau. The molecular data revealed that the highly specialized grade schizothoracine fishes were not a monophyletic group, but were the same as genera Gymnocypris and Schizogypsis. Our results indi-cated that the molecular phylogenetic relationships apparently reflected their geographical and historical associations with drainages, namely species from the same and adjacent drainages clustered together and had close relationships. The divergence times of different lineages were well consistent with the rapid uplift phases of the Tibetan Plateau in the late Cenozoic, suggesting that the origin and evolution of schizothoracine fishes were strongly influenced by environment changes resulting from the upheaval of the Tibetan Plateau. | HE DeKui CHEN YiFeng | 2007 | Chinese Science Bulletin2007，52，6： | 19 |
| 2 | Pd/activated carbon sorbents for mid-temperature capture of mercury from coal-derived fuel gas显示文摘Higher concentrations of Hg can be emitted from coal pyrolysis or gasification than from coal combustion, especially elemental Hg. Highly efficient Hg removal technology from coal-derived fuel gas is thus of great importance. Based on the very excellent Hg removal ability of Pd and the high adsorption abilities of activated carbon(AC) for H2 S and Hg, a series of Pd/AC sorbents was prepared by using pore volume impregnation, and their performance in capturing Hg and H2 S from coal-derived fuel gas was investigated using a laboratory-scale fixed-bed reactor. The effects of loading amount, reaction temperature and reaction atmosphere on Hg removal from coal-derived fuel gas were studied. The sorbents were characterized by N2 adsorption, X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS). The results indicated that the efficiency of Hg removal increased with the increasing of Pd loading amount, but the effective utilization rate of the active component Pd decreased significantly at the same time. High temperature had a negative influence on the Hg removal. The efficiency of Hg removal in the N2–H2S–H2–CO–Hg atmosphere(simulated coal gas) was higher than that in N2–H2S–Hg and N2–Hg atmospheres, which showed that H2 and CO, with their reducing capacity, could benefit promote the removal of Hg. The XPS results suggested that there were two different ways of capturing Hg over sorbents in N2–H2S–Hg and N2–Hg atmospheres. | Dekui Li Jieru Han Lina Han Jiancheng Wang Liping Chang | 2014 | Journal of Environmental Sciences2014，26，7： | 8 |
| 3 | Immobilization of Cu2+and Cd2+by earthworm manure derived biochar in acidic circumstance显示文摘Earthworm manure, the by-product obtained from the disposing of biowastes by earthworm breeding, is largely produced and employed as a feedstock for biochar preparation through pyrolysis. For repairing acidic soil or acidic electroplating effluent,biochar physicochemical properties would suffer from some changes like an acidic washing process, which hence affected its application functions. Pristine biochar(UBC)from pyrolysis of earthworm manure at 700°C and biochar treated by HCl(WBC) were comparatively investigated regarding their physicochemical properties, adsorption capability and adsorption mechanism of Cu^(2+) and Cd^(2+) from aqueous solution to explore the immobilization characteristics of biochar in acidic environment. After HCl treatment,the soluble ash content and phenolic-OH in the WBC sample was notably decreased against the increase of the carboxyl C_O, aromatic C_C and Si–O–Si, compared to that of UBC. All adsorption processes can be well described by Langmuir isotherm model. The calculated maximum adsorption capacity of Cu^(2+) and Cd^(2+) adsorption on UBC were 36.56 and 29.31 mg/g, respectively, which were higher than that of WBC(8.64 and 12.81 mg/g,respectively), indicating that HCl treatment significantly decreased biochar adsorption ability. Mechanism analysis revealed that alkali and alkaline earth metallic, salts(carbonates, phosphates and silicates), and surface functional groups were responsible for UBC adsorption, corresponding to ion exchange, precipitation and complexation,respectively. However, ion exchange made little contributions to WBC adsorption due to the great loss of soluble ash content. WBC adsorption was mainly attributed to the abundant exposure of silicates and surface functional groups(carboxyl C_O and aromatic C_C). | Zhanghong Wang Fei Shen Dekui Shen Yahui Jiang Rui Xiao | 2017 | Journal of Environmental Sciences2017，29，3： | 7 |
| 4 | Into Africa via docked India: a fossil climbing perch from the Oligocene of Tibet helps solve the anabantid biogeographical puzzle显示文摘The northward drift of the Indian Plate and its collision with Eurasia have profoundly impacted the evolutionary history of the terrestrial organisms, especially the ones along the Indian Ocean rim. Climbing perches(Anabantidae) are primary freshwater fishes showing a disjunct south Asian-African distribution,but with an elusive paleobiogeographic history due to the lack of fossil evidence. Here, based on an updated time-calibrated anabantiform phylogeny integrating a number of relevant fossils, the divergence between Asian and African climbing perches is estimated to have occurred in the middle Eocene(ca.40 Ma, Ma: million years ago), a time when India had already joined with Eurasia. The key fossil lineage is ?Eoanabas, the oldest anabantid known so far, from the upper Oligocene of the Tibetan Plateau.Ancestral range reconstructions suggest a Southeast Asian origin in the early Eocene(ca. 48 Ma) and subsequent dispersals to Tibet and then India for this group. Thereby we propose their westbound dispersal to Africa via the biotic bridge between India and Africa. If so, climbing perch precursors had probably followed the paleobiogeographical route of snakehead fishes, which have a slightly older divergence between African and Asian taxa. As such, our study echoes some recent molecular analyses in rejecting the previously held ‘‘Gondwana continental drift vicariance' or late Mesozoic dispersal scenarios for the climbing perches, but provides a unique biogeographical model to highlight the role of the preuplift Tibet and the docked India in shaping the disjunct distribution of some air-breathing freshwater fishes around the Indian Ocean. | Feixiang Wu Dekui He Gengyu Fang Tao Deng | 2019 | Science Bulletin2019，64，7： | 6 |
| 5 | Modeling assessment of tidal current energy in the Qiongzhou Strait, China显示文摘In the present study, an existing three-dimensional finite volume computational ocean model(FVCOM) was refined and configured including an algorithm for computing the power density and mean power density at Qiongzhou Strait of China. The refined model was validated with the measured tidal levels and tidal currents at different gauging stations. The model results are in reasonable agreement with the measured data. Based on the modeling results, we assess the resource of the tidal stream energy in the Qiongzhou Strait and discuss the temporal and the spatial distribution of the tidal current energy there. The conclusion is extracted: the higher power density occurs in the middle area of the strait, and lower at both sides. Characteristics of power density such as the maximum possibility speed, maximum power density during the spring tide period and the neap tide period, have the similar distribution. The southeast part and central area of the strait are of rich tidal current energy, where the maximum possibility speed can reach to 4.6 m/s, and the maximum power density of the spring tide period and the neap tide period can reach 5 996 and 467 W/m^2 separately in the surface layer The annual mean power density can reach 819 W/m^2. Statistical length of accumulative time of the velocity exceeding 0.7 m/s is about 4 717 h at local point during a year. The total theoretical tidal current energy resource is approximately189.55 MW and the available exploited energy on present technology condition is 249, 20.2 and 263 GW/a separately by using the methods FLUX, FARM and GC in the Qiongzhou Strait. | WU He YU Huaming DING Jie YUAN Dekui | 2016 | Acta Oceanologica Sinica2016，35，1： | 4 |
| 6 | Sulfur deposition in sour gas reservoirs:laboratory and simulation study显示文摘Sulfur deposition in the formation,induced by a reduction in the solubility of the sulfur in the gas phase,may significantly reduce the in flow performance of sour gas wells and some wells in sour gas reservoirs have even become completely plugged with deposited sulfur within several months.Accurate prediction and effective management of sulfur deposition are crucial to the economic viability of sour gas reservoirs.In this paper,a dynamic flow experiment was carried out to investigate formation damage resulting from sulfur deposition using an improved experimental method.The core sample was extracted from the producing interval of the LG2 well,LG gas field in the Sichuan Basin.The experimental temperature was 26 oC and the initial pressure was 19 MPa.The displacement pressure continuously decreased from 19 to 10 MPa,and the depletion process lasted 15 days.Then the core was removed and dried.The core mass and core permeability were measured before and after experiments.Experimental results indicated that the core mass increased from 48.372 g before experiment to 48.386 g afterwards,while the core permeability reduced from 0.726 to 0.608 md during the experiment.Then the core was analyzed with a scanning electron microscope(SEM) and energy-dispersive X-ray mapping.The deposition pattern and micro-distribution of elemental sulfur was observed and the deposited elemental sulfur distributed as a film around the pore surface.In addition,a preliminary three-dimensional,multi-component model was developed to evaluate the effect of sulfur deposition on production performance,and the effect of production rate on sulfur deposition was also investigated.Simulation results indicated that the stable production time would be shortened and the gas production rate would be decreased once sulfur deposited in the formation.The increase in deposited sulfur at high flow rates may be attributed to a bigger pressure drop than that at low gas flow rates.Gas production rate has a severe effect on sulfur saturation in the grid of producing well located in sour gas reservoir.The work suggests sulfur deposition should be considered to correctly predict production performance and gas production rate should be optimized in order to control or retard sulfur deposition during the development of sour gas reservoir. | Xiao Guo Zhimin Du Xuefeng Yang Yong Zhang Dekui Fu | 2009 | Petroleum Science2009，6，4： | 4 |

| 8 | Modified Functional Projective Synchronization of the Unidirectional and Bidirectional Hybrid Connective Star Network with Coupling Time-Delay显示文摘An unidirectional and bidirectional hybrid connective star network model with coupling time-delay is constructed in this paper. According to synchronization error systems, adaptive controllers for each node are structured by using the linear system stability method and the Lyapunov stability method. These adaptive controllers can realize the modified functional projective synchronization between each node of star network and an isolated node by argument and analysis. Finally, the corrective and effective of the adaptive controllers are illustrated by some numerical examples. | LI Dekui | 2019 | Wuhan University Journal of Natural Sciences2019，24，4： | 4 |
| 9 | Environmental Conditions of Barchan Dune and Barchan Chain-A Case Study from the Hexi Desert Area of Gansu显示文摘[Objective] The paper was to discuss why the top of tall barchan dunes and barchan chains widespread in single prevailing wind area had not been leveled by wind erosion. [Method] Based on the preliminary survey of distribution status,the morphological characteristics and environmental conditions of barchan dunes and barchan chains in Hexi desert area of Gansu were investigated in details. The significance of difference between samples and significance of correlation between indicators were examined via variance test. [Result] Barchan dunes and barchan chains in Hexi desert area of Gansu distributed at the leeward direction of desert fringe,generally in patch distribution. The distribution area was gravelly beach or cohesive gravel beach,with broader dune slack; winds in distribution area of barchan dunes and barchan chains blew obviously from one direction,while winds at other directions were light or occasionally strong but with low frequency;the barchan dune in the desert fringe of Hexi desert area of Gansu was relatively tall,while barchan chain was even more taller and larger. Coincidence or separation of the dune peak and the sand ridge might be related to distribution frequency of dominant prevailing wind or wind at opposite direction and the observation seasons.[Conclusion]Studying top stability of barchan dune has an important academic value in revealing blowing sand movement rule at desert fringe,invasion of sand flow,and expansion of desert. | Chang Zhaofeng Wang Qiangqiang Zhang Jianhui Xi Junqiang Wang Qi Zhang Dekui Tang Jinnian Zhang Huiwen | 2015 | Animal Husbandry and Feed Science2015，7，6： | 2 |
| 10 | Deformation and removal of semiconductor and laser single crystals at extremely small scales显示文摘Semiconductor and laser single crystals are usually brittle and hard,which need to be ground to have satisfactory surface integrity and dimensional precision prior to their applications.Improvement of the surface integrity of a ground crystal can shorten the time of a subsequent polishing process,thus reducing the manufacturing cost.The development of cost-effective grinding technologies for those crystals requires an in-depth understanding of their deformation and removal mechanisms.As a result,a great deal of research efforts were directed towards studying this topic in the past two or three decades.In this review,we aimed to summarize the deformation and removal characteristics of representative semiconductor and laser single crystals in accordance with the scale of mechanical loading,especially at extremely small scales.Their removal mechanisms were critically examined based on the evidence obtained from highresolution TEM analyses.The relationships between machining conditions and removal behaviors were discussed to provide a guidance for further advancing of the grinding technologies for those crystals. | Yueqin Wu Dekui Mu Han Huang | 2020 | International Journal of Extreme Manufacturing2020，2，1： | 2 |
| 11 | Development of DUS Test Guidelines for new varieties of Viburnum L.显示文摘Distinctness,uniformity and stability(DUS)Test Guidelines for new varieties of Viburnum L.were developed according to the principles and requirements of the International Union for the Protection of New Varieties of Plants(UPOV)and China.The development processes,including selection and determination of testing characteristics,determination of expression states of characteristics,selection of example varieties,determination of the order of characteristics,and assessment of distinctness,uniformity and stability,are described in this paper.There were 54 testing characteristics:24 qualitative characteristics(QL),15 quantitative characteristics(QN),15 pseudoqualitative characteristics(PQ)and 34 example varieties in the DUS Test Guidelines.Among the 54 testing characteristics,20 were asterisked and 34 were non-asterisked.Seven were selected for variety groupings and 18 were adopted in the Technical Questionnaire.The development of these DUS Test Guidelines will be useful for the application and protection of new Viburnum varieties.The Guidelines will provide technical support for DUS testing of Viburnum and serve as a reference for the development of new varieties in other countries. | Qichao Wu Dongjie Zhang Qing Zhang Dekui Zang | 2019 | Journal of Forestry Research2019，30，6： | 2 |
| 12 | Comparisons between Movement Speed of Main Types of Dunes:A Case Study of Desert Areas in Hexi Region of Gansu Province显示文摘In desert areas in Hexi region,11 barchan dunes,6 chains of barchan dunes,6 pyramid dunes,6 parabolic dunes and 6 accumulated sand-belts were chosen to study their movement speed based on images obtained by Google Earth in various periods.The results show that among the dunes,the movement of the barchan dunes was the fastest,followed by the chains of barchan dunes,and only the tops of the pyramid dunes swayed,while the parabolic dunes and accumulated sand-belts hardly moved forward.The higher the barchan dunes(or the chains of barchan dunes) were,the slower the movement was.On the contrary,the higher the pyramid dunes were,the faster the swing was.There was a positive correlation between the movement speed of the barchan dunes and the average wind speed of sandstorms. | CHANG Zhaofeng ZHU Shujuan SHI Xuegang ZHANG Jinhu LI Ya WANG Qi ZHANG Dekui DUAN Xiaofeng | 2016 | Journal of Landscape Research2016，8，6： | 2 |

| 14 | DDR1 promotes LoVo cell proliferation by regulating energy metabolism显示文摘Cellular energy metabolism dysregulation is associated with colorectal cancer(CRC)development and progression.Discoidin domain receptor 1a(DDR1a),one of the five DDR1 isoforms,is closely related to cell proliferation,invasion,and apoptosis in various tumors.Whether it participates in cellular metabolic reprogramming and regulates CRC initiation and progression remains unclear.In this study,we compared the expression of DDR1 in CRC tissues and adjacent tissues from 126 postoperative CRC samples.Moreover,lentivirus-mediated DDR1a overexpression and knockdown were performed in LoVo cells,and cell viability and proliferation were determined by CCK-8 and BrdU assays,respectively.Oxygen consumption rate,extracellular acidification rate,and lactate production were used to determine the effect of DDR1a on metabolic reprogramming.Clinically,CRC patients with high DDR1 expression had poor differentiation and were at an advanced TNM stage.DDR1a promoted LoVo cell proliferation,mitochondrial function,and extracellular acidification.Moreover,DDR1a knockdown inhibited intracellular lactic acid production in LoVo cells,while a pyruvate kinase inhibitor(diamide,200μM)significantly reversed this progression.Taken together,our results reveal that DDR1 plays a crucial role in maintaining intracellular environment homeostasis through metabolic reprogramming. | Bin Xiong Zehui Xie Feixue Song Huiling Chen Xiaojuan Wang Zhengxu Jin Tiyun Han Yi Li Dekui Zhang | 2022 | Acta Biochimica et Biophysica Sinica2022，54，5： | 1 |

These two new species can be distinguished from their congeners by the combination of characteristics of body shape, color pattern, lamina circularis, mental lobes, suborbital spine, subdorsal scales, and caudal peduncle. | Yongxia Chen Hao Chen Dekui He Yifeng Chen | 2018 | Zoological Systematics2018，43，2： | 1 |
| 19 | Electronic tattoos based on large-area Mo2C grown by chemical vapor deposition for electrophysiology显示文摘Tattoo electronics has attracted intensive interest in recent years due to its comfortable wearing and imperceivable sensing,and has been broadly applied in wearable healthcare and human-machine interface.However,the tattoo electrodes are mostly composed of metal films and conductive polymers.Two-dimensional(2D)materials,which are superior in conductivity and stability,are barely studied for electronic tattoos.Herein,we reported a novel electronic tattoo based on large-area Mo_(2)C film grown by chemical vapor deposition(CVD),and applied it to accurately and imperceivably acquire on-body electrophysiological signals and interface with robotics.High-quality Mo_(2)C film was obtained via optimizing the distribution of gas flow during CVD growth.According to the finite element simulation(FES),bottom surface of Cu foil covers more stable gas flow than the top surface,thus leading to more uniform Mo_(2)C film.The resulting Mo_(2)C film was transferred onto tattoo paper,showing a total thickness of~3μm,sheet resistance of 60-150Ω/sq,and skin-electrode impedance of~5×10^(5)Ω.Such thin Mo_(2)C electronic tattoo(MCET in short)can form conformal contact with skin and accurately record electrophysiological signals,including electromyography(EMG),electrocardiogram(ECG),and electrooculogram(EOG).These body signals collected by MCET can not only reflect the health status but also be transformed to control the robotics for human-machine interface. | Shiyu Wang Xin Wang Weifeng Zhang Xiaohu Shi Dekui Song Yan Zhang Yan Zhao Zihan Zhao Nan Liu | 2023 | Nano Research2023，16，3： | 1 |
