| 2 | Investigation of a novel self-sealing pore micro-arc oxidation film on AM60 magnesium alloy显示文摘Micro-arc oxidation(MAO)is one of the promising methods to improve the corrosion resistance of magnesium alloys.However,there are plenty of micro-pores in the traditional MAO films,deteriorating their protection property.A novel self-sealing pore MAO film was developed in this paper.The morphologies and chemical composition of the film were detected by scanning electron microscopy(SEM)and energy dispersive X-ray spectroscopy(EDX).The corrosion behavior was investigated by electrochemical and salt spray tests.The possible film formation and corrosion mechanisms were proposed.The self-sealing pore film presents a blue appearance.Most of the micro-pores in the surface of the film are sealed during the film formation process.The chemical composition of the film mainly contains Mg,O,Ti,F and P.The self-sealing pore film exhibits better corrosion resistance compared with the traditional silicate film.Especially,the self-sealing pore film keeps intact after salt spray test for 2000 h,which can be attributed to its high compactness. | Yingwei Song Kaihui Dong Dayong Shan En-Hou Han | 2013 | Journal of Magnesium and Alloys2013，1，1： | 23 |
| 3 | Assessment of locomotion behavioral defects induced by acute toxicity from heavy metal exposure in nematode Caenorhabditis elegans显示文摘Locomotion behaviors are susceptible to disruption by a broad spectrum of chemicals and environmental stresses. However, no systematic testing of locomotion behavior defects induced by metal exposure has been conducted in the model organism of nematode Caenorhabditis elegans. In this study, the acute toxicity from heavy metal exposure on the locomotion behaviors was analyzed in nematodes. Endpoints of head thrash, body bend, forward turn, backward turn, and Omega/U turn were chosen to evaluate the locomotion behavioral defects. Our data suggest that the endpoints of head thrash, body bend, and forward turn will be useful for the evaluation of heavy metal toxicity in nematodes. The endpoint of head thrash could detect the toxicity from Cd, Co, Cr, Cu, Hg, and Pb exposures at a low concentration (2.5 μmol/L). The endpoint of body bend could be explored to evaluate the toxicity from all assayed heavy metal exposures at different concentrations, whereas the endpoint of forward turn will be more useful for the evaluation of heavy metal toxicity at high concentrations. Thus, endpoints of these locomotion behaviors establish a fast and economic way to assess the presence of acute toxicity from heavy metal exposure in nematode C. elegans. | Dayong WANG Xiaojuan XING | 2008 | Journal of Environmental Sciences2008，20，9： | 21 |
| 4 | Conodont Evidence for the Age of the Panxian Fauna,Guizhou,China显示文摘Detailed conodont analysis on the Yangjuan-Chupiwa section,Xinmin,Panxian County,Guizhou Province,revealed a conodont sequence including four Anisian conodont zones,viz.Nicoraella germanica Zone,Nc.kockeli Zone,Paragondolella bifurcata Zone and Neogondolella constricta Zone.These zones indicate that the upper Guanling Formation consists of strata from the Bithynian to the Illyrian of the Anisian.Appearance of Neogondolella constricta suggests that the Anisian/Ladinian boundary might be in the overlying Yangliujing Formation.The Panxian Fauna with well-preserved marine reptile and fish fossils is proved to belong to the lower part of the conodont Nc.kockeli Zone in the studied area.Thus,the age of the Panxian Fauna could be the early Pelsonian of the Anisian. | SUN Zuoyu SUN Yuanlin HAO Weicheng JIANG Dayong | 2006 | Acta Geologica Sinica(English Edition)2006，80，5： | 19 |

| 6 | Scattering of SH waves induced by a symmetrical V-shaped canyon: a unified analytical solution显示文摘This paper reports a series solution of wave functions for two-dimensional scattering and diffraction of plane SH waves induced by a symmetrical V-shaped canyon with different shape ratios. A half-space with a symmetrical V-shaped canyon is divided into two sub-regions by using a circular-arc auxiliary boundary. The two sub-regions are represented by global and local cylindrical coordinate systems, respectively. In each coordinate system, the wave field satisfying the Helmholtz equation is represented by the separation of variables method, in terms of the series of both Bessel functions and Hankel functions with unknown complex coefficients. Then, the two wave fields are described in the local coordinate system using the Graf addition theorem. Finally, the unknown coefficients are sought by satisfying the continuity conditions of the auxiliary boundary. To consider the phase characteristics of the wave scattering, a parametric analysis is carried out in the time domain by assuming an incident signal of the Ricker type. Surface and subsurface transient responses demonstrate the characteristics and mechanisms of wave propagating and scattering. | Zhang Ning Gao Yufeng Li Dayong Wu Yongxin Zhang Fei | 2012 | Earthquake Engineering and Engineering Vibration2012，11，4： | 19 |
| 7 | Dualistic water cycle pattern and its evolution in Haihe River basin显示文摘The Haihe River basin is widely recognized as an area in China which is most severely affected by human activities.The water resources utilization and recycling in the basin is very complex, and the characteristic of the dualistic water cycle is becoming more and more prominent.The ever-growing demand of water for modern industry and domestic life nearly dries up all the natu-ral runoff.Meanwhile, industrial, agricultural and domestic wastewater discharges cause severe deterioration in water quality.Consequently, many of water courses are either dried out or being heavily polluted.Modern water resources management can no longer rely on the 'monitoring-rehabilitation' model which was originally developed based on the natural water cycle.This paper analyzes the critical characteristics, water balance, and evolution of water flux process based on the theory of dualistic water cycle.Referring to the water cycle in the Haihe River basin, a schematic diagram was drawn to describe the dualistic water cycle pattern.Ten different parameters affecting mainly the evolution of water flux in the 'dualistic water cycle' are closely examined using the newly-collected data.As a result, this paper proposes several water management and control strategies to achieve healthy wa-ter status for the Haihe River basin. | LIU JiaHong QIN DaYong WANG Hao WANG MingNa YANG ZhiYong | 2010 | Chinese Science Bulletin2010，55，16： | 18 |

| 12 | Crustal stress field in Yunnan: implication for crust-mantle coupling显示文摘We applied the g CAP algorithm to determine239 focal mechanism solutions 3:0 M We 6:0T with records of dense Chin Array stations deployed in Yunnan,and then inverted 686 focal mechanisms(including 447 previous results) for the regional crustal stress field with a damped linear inversion. The results indicate dominantly strike-slip environment in Yunnan as both the maximum(r1) and minimum(r3) principal stress axes are sub-horizontal. We further calculated the horizontal stress orientations(i.e., maximum and minimum horizontal compressive stress axes: S H and S h, respectively) accordingly and found an abrupt change near *26°N. To the north, S H aligns NW-SE to nearly E-W while S h aligns nearly N-S. In contrast, to the south, both S H and S h rotate laterally and show dominantly fan-shaped patterns. The minimum horizontal stress(i.e., maximum strain axis) S h rotates from NW-SE to the west of Tengchong volcano gradually to nearly E-W in west Yunnan, and further toNE-SW in the South China block in the east. The crustal strain field is consistent with the upper mantle strain field indicated by shear-wave splitting observations in Yunnan but not in other regions. Therefore, the crust and upper mantle in Yunnan are coupled and suffering vertically coherent pure-shear deformation in the lithosphere. | Zhigang Xu Zhouchuan Huang Liangshu Wang Mingjie Xu Zhifeng Ding Pan Wang Ning Mi Dayong Yu Hua Li | 2016 | Earthquake Science2016，29，2： | 15 |
| 13 | Laparoscopic versus open pancreaticoduodenectomy for pancreatic ductal adenocarcinoma:a propensity score matching analysis显示文摘Background:A growing body of evidence supports the use of laparoscopic pancreaticoduodenectomy(LPD)as an efficient and feasible surgical technique.However,few studies have investigated its applicability in pancreatic ductal adenocarcinoma(PDAC),and the long-term efficacy of LPD on PDAC remains unclear.This study aimed to compare the short-and long-term outcomes between LPD and open pancreaticoduodenectomy(OPD)for PDAC.Methods:The data of patients who had OPD or LPD for PDAC between January 2013 and September 2017 were retrieved.Their postoperative outcomes and survival were compared after propensity score matching.Results:A total of 309 patients were included.After a 2:1 matching,93 cases in the OPD group and 55 in the LPD group were identified.Delayed gastric emptying(DGE),particularly grade B/C DGE,occurred less frequently in the LPD group than in the OPD group(1.8%vs.36.6%,P<0.001;1.8%vs.22.6%,P=0.001).The overall complication rates were significantly lower in the LPD group than in the OPD group(49.1%vs.71.0%,P=0.008),whereas the rates of major complications were similar(10.9%vs.14.0%,P=0.590).In addition,the median overall survival was comparable between the two groups(20.0 vs.18.7 months,P=0.293).Conclusion:LPD was found to be technically feasible with efficacy similar to OPD for patients with PDAC. | Wentao Zhou Weiwei Jin Dansong Wang Chao Lu Xuefeng Xu Renchao Zhang Tiantao Kuang Yucheng Zhou Wenchuan Wu Dayong Jin Yiping Mou Wenhui Lou | 2019 | Cancer Communications2019，39，1： | 14 |

| 15 | Prolonged manganese exposure induces severe deficits in lifespan,development and reproduction possibly by altering oxidative stress response in Caenorhabditis elegans显示文摘We examined the possible multiple defects induced by acute and prolonged exposure to high levels of manganese(Mn) solution by monitoring the endpoints of lifespan,development,reproduction,and stress response.Our data suggest that acute exposure(6 h) to Mn did not cause severe defects of life span,development,and reproduction,similarly,no significant defect could be found in animals exposed to a low concentration of Mn(2.5 μmol/L) for 48 h.In contrast,prolonged exposure(48 h) to high Mn concentrations(75 and 200 μmol/L) resulted in significant defects of life span,development,and reproduction,as well as the increase of the percentage of population with hsp-16.2::gfp expression indicating the obvious induction of stress responses in exposed animals.Moreover,prolonged exposure(48 h) to high concentrations(75 and 200 μmol/L) of Mn decreased the expression levels of antioxidant genes of sod-1,sod-2,sod-3,and sod-4 compared to control.Therefore,prolonged exposure to high concentrations of Mn will induce the severe defects of life span,development,and reproduction in nematodes possibly by affecting the stress response and expression of antioxidant genes in Caenorhabditis elegans. | XIAO Jing | 2009 | Journal of Environmental Sciences2009，21，6： | 13 |

| 18 | Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders. | XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu | 2015 | Science China(Life Sciences)2015，58，9： | 12 |
| 19 | New strategy for designing orangish-redemitting phosphor via oxygen-vacancyinduced electronic localization显示文摘Phosphor-converted white-light-emitting diodes(pc-WLED)have been extensively employed as solid-state lighting sources,which have a very important role in people’s daily lives.However,due to the scarcity of the red component,it is difficult to realize warm white light efficiently.Hence,red-emitting phosphors are urgently required for improving the illumination quality.In this work,we develop a novel orangish-red La_(4)GeO_(8):Bi^(3+) phosphor,the emission peak of which is located at 600 nm under near-ultraviolet(n-UV)light excitation.The full width at half maximum(fwhm)is 103 nm,the internal quantum efficiency(IQE)exceeds 88%,and the external quantum efficiency(EQE)is 69%.According to Rietveld refinement analysis and density functional theory(DFT)calculations,Bi^(3+) ions randomly occupy all La sites in orthorhombic La_(4)GeO_(8).Importantly,the oxygen-vacancy-induced electronic localization around the Bi3+ions is the main reason for the highly efficient orangish-red luminescence.These results provide a new perspective and insight from the local electron structure for designing inorganic phosphor materials that realize the unique luminescence performance of Bi^(3+) ions. | Yi Wei Gongcheng Xing Kang Liu Guogang Li Peipei Dang Sisi Liang Min Liu Ziyong Cheng Dayong Jin Jun Lin | 2019 | Light(Science & Applications)2019，8，1： | 12 |
| 20 | β-diversity Patterns of Plant Community in Fragmented Habitat in a Degenerated Meadow in Songnen Plain,China显示文摘A number of isolated islands of Leymus chinensis + herbosa community were investigated in fragmented habitat islands,by Braun-Blanquet field survey approach,in a degenerated meadow in the Songnen Plain,China in 2007.These islands were classified as large,medium,and small scales on the basis of the island area(100-1000m2,large island;50-100m2,middle island;10-50m2,small island).Each scale of the investigation involved eight islands.The responses of β-diversity patterns of plant taxon to the habitat fragmentation at local community and metacommunity levels were analyzed on different scales of 24 isolated islands.The results indicated that at the local community level,there were 57 species belonging to 20 families and 49 genera in large islands,49 species belonging to 16 families and 40 genera in middle islands,and 27 species belonging to eight families and 23 genera in small islands.β-diversity indexes for species,genus and family in large,middle,and small islands varied greatly,and the highest value of the indexes was not noted in the largest island.However,the average of the data obtained at the three scales showed that across large islands,Whittaker indexes were low and Bray-Curtis similarity indexes were high,while across small islands,Whittaker indexes were high and Bray-Curtis similarity indexes were low.At the metacommunity level,Whittaker indexes for species and genus showed a great significantly negative double logarithmic correlation(p<0.01) with the island area,whereas the Bray-Curtis indexes for species,genus and family showed a great significantly positive double logarithmic correlation(p<0.01) with the island area.At both local community and metacommunity levels,turnovers of species and genus could respond more sensitively to spatial changes of plant diversity patterns than that of family.Hence,the species and the genus could be used for the analysis of β-diversity patterns of plant community. | HAN Dayong LI Haiyan YANG Yunfei | 2009 | Chinese Geographical Science2009，19，4： | 11 |
