| 1 | Source mechanism of strong aftershocks (M_s≥5.6) of the 2008/05/12 Wenchuan earthquake and the implication for seismotectonics显示文摘Dozens of >M5, hundreds of >M4, and much more >M3 aftershocks occurred after the 2008/05/12 Wenchuan earthquake, which were well recorded by permanent and portable seismic stations. After relocated with P arrival, the >M3 aftershocks show two trends of distribution, with most of the aftershocks located along the north-east strike consistent with Longmenshan fault system, yet there is a north-west trend around the epicenter. It seems that substantially more aftershocks occur in regions with crystalline bedrocks. Then we collected waveform data from National Digital Seismograph Network and regional seismograph network of China, and employed 'Cut and Paste' method to obtain focal mechanisms and depths of the big aftershocks (M≥5.6). While most of those aftershocks show thrust mechanism, there are some strike slip earthquakes in the northern-most end of the rupture. Focal mechanisms show that the events located on the southern part of central Beichuan-Yingxiu Fault (BY) are mainly thrust earthquakes, which is consistent with initial mechanism of the main shock rupture. In the north part the aftershocks along the BY are also dominated by thrust slip, which is quite different from the right slip rupture of the main shock. Around Qingchuan-Pingwu Fault, the focal mechanisms are dominated by right-slip rupture with large depths (~18 km). So we suspected that in the north part the main shock might rupture on two faults: Beichuan Fault and Qingchuan-Pingwu Fault. The complex pattern of aftershock mechanisms argues for presence of a complicated fault system in the Longmenshan area. | ZHENG Yong1,2,MA HongSheng3,Lü Jian4,NI SiDao5,LI YingChun6 & WEI ShengJi2 1 Institute of Geodesy and Geophysics,Chinese Academy of Sciences,Wuhan 430077,China 2 Institute of Geophysics,Chinese Earthquake Administration,Beijing 100086,China 3 Institute of Earthquake Science,Chinese Earthquake Administration,Beijing 100086,China 4 Earthquake Administration of Jiangxi Province,Nanchang 330039,China 5 School of Earth and Space Science,University of Science and Technology of China,Hefei 230026,China 6 Earthquake Administration of Jiangsu Province,Nanjing 210014,China | 2009 | Science China Earth Sciences2009，52，6： | 100 |
| 2 | Current concepts on osteonecrosis of the femoral head显示文摘It is estimated that 20000 to 30000 new patients are diagnosed with osteonecrosis annually accounting for approximately 10% of the 250000 total hip arthroplasties done annually in the United States. Thelack of level 1 evidence in the literature makes it difficult to identify optimal treatment protocols to manage patients with pre-collapse avascular necrosis of the femoral head, and early intervention prior to collapse is critical to successful outcomes in joint preserving procedures. There have been a variety of traumatic and atraumatic factors that have been identified as risk factors for osteonecrosis, but the etiology and pathogenesis still remains unclear. Current osteonecrosis diagnosis is dependent upon plain anteroposterior and frog-leg lateral radiographs of the hip, followed by magnetic resonance imaging(MRI). Generally, the first radiographic changes seen by radiograph will be cystic and sclerotic changes in the femoral head. Although the diagnosis may be made by radiograph, plain radiographs are generally insufficient for early diagnosis, therefore MRI is considered the most accurate benchmark. Treatment options include pharmacologic agents such as bisphosphonates and statins, biophysical treatments, as well as joint-preserving and joint-replacing surgeries. the surgical treatment of osteonecrosis of the femoral head can be divided into two major branches: femoral head sparing procedures(FHSP) and femoral head replacement procedures(FHRP). In general, FHSP are indicated at pre-collapse stages with minimal symptoms whereas FHRP are preferred at post-collapse symptomatic stages. It is difficult to know whether any treatment modality changes the natural history of core decompression since the true natural history of core decompression has not been delineated. | Joaquin Moya-Angeler Arianna L Gianakos Jordan C Villa Amelia Ni Joseph M Lane | 2015 | World Journal of Orthopedics2015，6，8： | 94 |
| 3 | Identifi cation of a novel male sterile wheat mutant dms conferring dwarf status and multi-pistils显示文摘Plant height and fertility are two important traits of wheat(Triticum aestivum L.), whose mutants are ideal materials for studies on molecular mechanisms of stem and floral organ development. In this study, we identified a dwarf, multi-pistil and male sterile(dms hereafter) wheat mutant from Zhoumai 18. Simple sequence repeat(SSR) marker assay with 181 primer pairs showed that only one locus of GWM148-2B was divergent between Zhoumai 18 and dms. There were three typical phenotypes in the progeny of dms, tall(T; ca. 0.8 m), semi-dwarf(M; ca. 0.6 m) and dwarf(D; under 0.3 m) plants. Morphological investigation indicated that the internode length of M was shortened by about 20–50 mm each; the internode number of D was 2 less than that of T and Zhoumai 18, and its internode length was shorter also. The pollen vigor and hybridization test demonstrated that dms mutant was male sterility. Segregated phenotypes in progeny of M suggested that the multi-pistils and sterility were controlled by one recessive gene locus which was designated as dms temporarily, and the plant height was controlled by a semi-dominant gene locus Dms. Therefore, progeny individuals of the dms had three genotypes, Dms Dms for tall plants, Dmsdms for semi-dwarf plants and dmsdms for dwarf plants. The mutant progenies were individually selected and propagated for more than 6 generations, thus a set of near isogenic lines of T, M and D for dms were developed. This study provides a set germplasms for studies on molecular mechanisms of wheat stem and spike development. | DUAN Zong-biao SHEN Chun-cai LI Qiao-yun Lü Gui-zhen NI Yong-jing YU Dong-yan NIU Ji-shan | 2015 | Journal of Integrative Agriculture2015，14，9： | 6 |

| 5 | Oil charging history and pathways of the Ordovician carbonate reservoir in the Tuoputai region,Tarim Basin,NW China显示文摘Geochemical analysis of 64 oils sampled from an Ordovician carbonate reservoir in the Tuoputai region was undertaken to study the composition of molecular markers. All the oils have similar geochemical characteristics and belong to a single oil family. They are presumed to derive from the same source kitchen and have similar oil charging history. A histogram of homogenization temperatures(Th) of aqueous inclusions in reservoir rocks shows a bimodal distribution pattern, indicating that the Ordovician reservoir has been charged twice. Coupling the measured Th(°C) with the burial and geothermal histories reconstructed using 1D basin modeling, we relate the homogenization temperature to the relevant geological ages: i.e.,425–412 and 9–4 Ma, corresponding to the Middle to Late Silurian and the Miocene to Pliocene, respectively. The oil filling orientation and pathways are traced using molecular indicators related to alkyldibenzothiophenes and benzo[b]naphthothiophenes. The oil charging orientation is from south to north generally. It can be predicted that the Ordovician reservoirs were sourced from a kitchen located to the south of the Tuoputai region, most probably between the Awati and Manjiaer Depressions. Traps located in the southern side of the Tuoputai region, along the oil charging pathways, should therefore be preferred oil exploration targets. | Rong-Hui Fang Mei-Jun Li Hai-Tao Lü T.-G.Wang Yuan Yuan Yong-Li Liu Zhi-Yong Ni | 2017 | Petroleum Science2017，14，4： | 5 |
| 6 | Grassland Degradation and Its Control in Region AroundQinghai Lake显示文摘A quite severe degradation was found in all seven types of grasslands in the study area involving 12counties of the northwestern Qinghai Province. The slightly, moderately and severely degraded grasslandsoccupied 49.7%, 32.0% and 18.3% of the area respectively. The major factors resulting in the degradationwere overgrazing, the damages from mice and grasshopper and blown sands, and improper use of grasslands.The measures to deal with these problems should be: 1) to make livestock development in accordancewith grassland carrying capacity for animals; 2) to build more artificial grasslands with a stable and highergraas yield; 3) to put more widely the rotation grazing system into practice; 4) to clear up the poisonousgrass species; and 5) to adopt more effective measures to deal with the damages to grasslands by mice andgrasshoppers. | JIANG JIANJUN NI SHAOXIANG GONG AIQI WANG WEIJUN ZHA YONG WANG JIECHENG F.

| 7 | Degradation of PCDD/Fs in MSWI fly ash using a microwave-assisted hydrothermal process显示文摘In this work,microwave treatment was introduced to a hydrothermal treatment process to degrade PCDD/Fs(Polychlorinated dibenzo-p-dioxins and dibenzofurans)in municipal solid waste incineration(MSWI)fly ash.Three process additives(NaOH,Na2 HPO4,H2 O),temperatures(150℃,185℃,220℃)and reaction times(1 h,2 h,3 h)were investigated to identify their effect on the disposal of fly ash samples through orthogonal experiments.High-resolution gas chromatography–mass spectrometry(HRGC/MS)was applied to determine the PCDD/F concentrations in MSWI fly ash.The experimental results revealed that 83.7%of total PCDD/Fs was degraded.Reaction temperature was the most important factor for the degradation of the total PCDD/Fs.Both direct destruction and chlorination reactions(the chlorination degree of PCDFs increased)took part in the degradation of PCDD/Fs in fly ash,which was a new discovery.Several PCDD/F indexes determined by the concentration of indicative congeners were found to quantitatively characterize the dioxin toxicity of the fly ash.Furthermore,heavy metals in the fly ash sample were solidified using microwave-assisted hydrothermal treatment,which provided an experimental basis for the simultaneous disposal of dioxins and heavy metals.Thus,the microwave-assisted hydrothermal process should be considered for the future disposal of MSWI fly ash. | Qili Qiu Xuguang Jiang Guojun Lü Zhiliang Chen Shengyong Lu Mingjiang Ni Jianhua Yan Xiaobing Deng | 2019 | Chinese Journal of Chemical Engineering2019，27，7： | 3 |
| 8 | Isolation and Expression Analysis of Two Genes Encoding Cinnamate 4-Hydroxylase from Cotton(Gossypium hirsutum)显示文摘Two genes(GhC4H1 and GhC4H2) that encode putative cotton cinnamate 4-hydroxylases that catalyze the second step in the phenylpropanoid pathway were isolated from developing cotton fibers. GhC4H1 and GhC4H2 each contain open reading frames of 1 518 base pairs(bp) in length and both encode proteins consisting of 505 amino acid residues. They are 90.89% identical to each other at the amino acid sequence level and belong to class I of plant C4 Hs. GhC4H1 and GhC4H2 genomic DNA are 2 247 and 2 161 bp long, respectively, and contain two introns located at conserved positions relative to the coding sequence. GhC4H1 and GhC4H2 promoters were isolated and found to contain many cis-elements(boxes P, L and AC-I element) previously identified in the promoters of other phenylpropanoid pathway genes. Histochemical staining showed GUS expression driven by the GhC4H1 and GhC4H2 promoters in ovules and fibers tissues. GhC4H1 and GhC4H2 were also widely expressed in other cotton tissues. GhC4H2 expression reached its highest level during the elongation stage of fiber development, whereas GhC4H1 expression increased during the secondary wall development period in cotton fibers. Our results contribute to a better understanding of the biochemical role of GhC4H1 and GhC4H2 in cotton fiber development. | NI Zhi-yong LI Bo Neumann M Peter Lü Meng FAN Ling | 2014 | Journal of Integrative Agriculture2014，13，10： | 3 |

| 11 | Effect of slag composition on the cleanliness of 28MnCr5 gear steel in the refining processes显示文摘The equilibrium reaction between CaO -Al_2O_3-SiO _2-MgO slag and 28 MnC r5 molten steel was calculated to obtain the suitable slag composition which is effective for decreasing the oxygen content in molten steel. The dissolved oxygen content [O] in molten steel under different top slag conditions was calculated using a thermodynamic model and was measured using an electromotive force method in slag–steel equilibrium experiments at 1873 K. The relations among [O], the total oxygen content(T.O), and the composition of the slag were investigated. The experimental results show that both [O] and T.O decrease with decreasing SiO_2 content of the slag and exhibit different trends with the changes in the CaO /Al_2O_3 mass ratio of the slag. Increasing the CaO /Al_2O_3 mass ratio results in a decrease in [O] and an increase in T.O. To ensure that T.O ≤ 20 ppm and [O] ≤ 10 ppm, the SiO _2 content should be controlled to <5wt%, and the CaO /Al_2O_3 mass ratio should be in the range from 1.2 to 1.6. | Wen-liang Dong Hong-wei Ni Hua Zhang Ze-an Lü | 2016 | International Journal of Minerals,Metallurgy and Materials2016，23，3： | 3 |

| 14 | Comparative study of oxidation ability between boron-doped diamond (BDD) and lead oxide (PbO_2) electrodes显示文摘The electrochemical oxidation capabilities of two high-performance electrodes,the boron-doped diamond film on Ti (Ti/BDD) and the lead oxide film on Ti (Ti/PbO2),were discussed.Hydroxyl radicals (·HO) generated on the electrode surface were detected by using p-nitrosodimethylaniline (RNO) as the trapping reagent.Electrochemical oxidation measurements,including the chemical oxygen demand (COD) removal and the current efficiency (CE),were carried out via the degradation of p-nitrophenol (PNP) under the galvanostatic condition.The results indicate that an indirect reaction,which is attributed to free hydroxyl radicals with high activation,conducts on the Ti/BDD electrode,while the absorbed hydroxyl radicals generated at the Ti/PbO2 surface results in low degradation efficiency.Due to quick mineralization which combusts PNP to CO2 and H2O absolutely by the active hydroxyl radical directly,the CE obtained on the Ti/BDD electrode is much higher than that on the Ti/PbO2 electrode,notwithstanding the number of hydroxyl radicals produced on PbO2 is higher than that on the BDD surface. | Jun-jun Wei Xiu-ping Zhu Fan-xiu L Jin-ren Ni | 2011 | International Journal of Minerals,Metallurgy and Materials2011，18，5： | 2 |

| 17 | Crustal S-wave velocity structure of the Yellowstone region using a seismic ambient noise method显示文摘The Yellowstone volcano is one of the largest active volcanoes in the world,and its potential hazards demand detailed seismological and geodetic studies.Previous studies with travel time tomography and receiver functions have revealed a low-velocity layer in the crust beneath the Yellowstone volcano,suggesting the presence of a magma chamber at depth.We use ambient seismic noise from regional seismic stations to retrieve short-period surface waves and then study the shallow shear velocity structure of the Yellowstone region by surface wave dispersion analysis.We first obtained a crustal model of the area outside of the Yellowstone volcano and then constructed an absolute shear wave velocity structure in combination with receiver function results for the crust beneath the Yellowstone volcano.The velocity model shows a low-velocity layer with shear velocity at around1.3 km/s,suggesting that a large-scale magma chamber exists at shallow levels within the crust of the Yellowstone volcanic region. | Yan Lü Sidao Ni Jun Xie Yingjie Xia Xiangfang Zeng Bin Liu | 2013 | Earthquake Science2013，26，5： | 2 |
| 18 | Knockout of glutathione peroxidase 5 down-regulates the piRNAs in the caput epididymidis of aged mice显示文摘The mammalian epididymis not only plays a fun dame ntal role in the maturati on of spermatozoa,but also provides protecti on agai nst various stressors.The foremost among these is the threat posed by oxidative stress,which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids,proteins,and nucleic acids.In mice,the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5(GPX5)as a major luminal scavenger in the proximal caput epididymidal segment.Accordingly,the loss of GPX5^-/-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx57 mice.To explore the underlying mechanism,we have conducted transcriptomic analysis of caput epididymidal epithelial cells from aged(13 months old)Gpx5^-/-m mice.This analysis revealed the dysregulation of several thousand epididymal mRNA transcripts,in eluding the downregulation of a subgroup of piRNA pathway gen es,in aged Gpx5^-/-mice.In agreeme nt with these fin dings,we also observed the loss of piRNAs,which potentially bind to the P-element-induced wimpy testis(PlWI)-like proteins PIWIL1 and PIWIL2.The absence of these piRNAs was correlated with the elevated mRNA levels of their putative gene targets in the caput epididymidis of Gpx5^-/-mice.Importantly,the oxidative stress response genes tend to have more targeting piRNAs,and many of them were among the top increased genes upon the loss of GPX5^-/-.Taken together,our findings suggest the existence of a previously uncharacterized somatic piRNA pathway in the mammalian epididymis and its possible invoIvement in the aging and oxidative stress-mediated responses. | Chen Chu Lu Yu Joelle Henry-Berger Yan-Fei Ru Ayhan Kocer Alexandre Champroux Zhi-Tong Li Miao He Sheng-Song Xie Wu-Bin Ma Min-Jie Ni Zi-Mei Ni Yun-Li Guo Zhao-Liang Fei Lan-Tao Gou Qiang Liu Samanta Sharma Yu Zhou Mo-Fang Liu Charlie Degui Chen Andrew L Eamens Brett Nixon Yu-Chuan Zhou Joel R Drevet Yong-Lian Zhang | 2020 | Asian Journal of Andrology2020，22，6： | 2 |
