| 1 | Tectonic implications of Late Paleozoic stratigraphic distribution in Northeast China and adjacent region显示文摘An analysis of the distribution of the Late Paleozoic strata on Northeast China and adjacent region reveals a zonal pattern of the distribution around the core of the Jiamusi-Mongolia Block.The main part of Late Paleozoic marine strata in this area is considered the continental margin deposits of the Jia-musi-Mongolia Block by analyzing the stratigraphic contact relationship,lithofacies,etc.The results are exhibited in a series of tectonic paleogeographic maps.This presents an important proof for the foundation of the Jiamusi-Mongolia Block,and confines the forming time of Jiamusi-Mongolia Block to the Late Silurian. | ChengWen Wang YueWu Sun Ning Li GuoWei Zhao XiaoQin Ma | 2009 | Science China Earth Sciences2009，52，5： | 36 |

| 3 | BiVO_(4),Bi_(2)WO_(6) and Bi_(2)MoO_(6) photocatalysis:A brief review显示文摘In recent years,photocatalytic technologies have been extensively studied and diffusely used in water splitting,decomposition of organic pollutants,reduction of carbon dioxide,etc.As a type of eye-catching semiconductors,BiVO_(4),Bi_(2)WO_(6),and Bi_(2)MoO_(6) (denoted as BiaAOb)have become a hotspot in photocatalytic researches due to their crystal structure stability,high light quantum and electronic transmission efficiency,and outstanding energy utilization capacity.However,pristine BiaAOb(A=V,W,and Mo)possesses several drawbacks,such as low separation efficiency of photo-excited electron-hole pairs,low specific surface area,as well as the poor quantum utilization,which restrict their photocatalytic performance.Considerable efforts,such as nanostructure modification,surface engineering,and heterojunction/homojunction fabrication,have been conducted to solve these problems.This integrated review aims to sum up recent advances in current studies on fabrication of high efficiency BiaAOb photocatalysts to accelerate the developments of BiaAOb-based materials in the photocatalysis(PC)field.The current challenges and prospects of BiaAOb are emphasized which stretches the existing fundamental theories of PC as well as provide a promising strategy to fabricate high efficiency BiaAOb catalysts to control environmental pollution and assist the sustainable development of energy. | Xintong Liu Shaonan Gu Yanjun Zhao Guowei Zhou Wenjun Li | 2020 | Journal of Materials Science & Technology2020，56，21： | 13 |
| 4 | Geochemistry of the subduction-related magmatic rocks in the Dahong Mountains, northern Hubei Province--Constraint on the existence and subduction of the eastern Mianlüe oceanic basin显示文摘The existence and subduction of the eastern Mianl黣 oceanic basin in the south Qinling belt are keys to understand the Qinling orogen. Based on geological mapping, several volcanic slices have been identified in Tumen, Zhoujiawan, Xiaofu and Yuantan areas, which distribute in the northern margin of the Dahong Mountains (DHM), and thrust into the Sanli-gang-Sanyang fault. These slices consist mainly of diabases, basaltic-andesitic lavas, pyroclastic rocks and a minor tuff. The geochemistry of the basalts, andesites,and diabases is characterized by depleting in Nb and Ta, enriching in Th and LILE (e.g.K, Rb, Ba), and undifferentiating in HFSE. These geochemical characteristics suggest that the original magma of these rocks was derived from a mantle wedge above a subduction zone, and formed in an island-arc setting in Carboniferous-early Triassic. Comparing with the ophiolites and island-arc volcanic rocks in Mianxian-Leyang area to the west, it is reasonable to consider that there had been an oceanic basin connecting with the Mianle ancient ocean to the westward, distributing along the south edge of the Tongbai-Dabie block. In view of the ophiolite in Huashan area and these island-arc volcanic rocks along the north of the Dahong Mountains, it is suggested that there had been a plate tectonic evolutionary history with oceanic basin rifting and subduction in this region. | DONG Yunpeng, ZHANG Guowei, ZHAO Xia, YAO Anping & LIU Xiaoming The Key Laboratory of Continental Dynamics, Ministry of Education, Department of Geology, Northwest University, Xi抋n 710069,China | 2004 | Science China Earth Sciences2004，47，4： | 12 |
| 5 | Deep seismic sounding data reveal the crustal structures beneath Zoigê basin and its surrounding folded orogenic belts显示文摘Songpan-Garze massif is located at the turning position of tectonics from the nearly west-east direction to the nearly north-south direction in the northeastern margin of Tibetan Plateau,with Zoigê basin in the centre of the massif.In this paper,we build a crustal structure model of Zoigê basin and its surrounding folded orogenic belts using the deep seismic sounding data in this region.We also discuss structures and properties of the basement in Zoigê basin,tectonic relations between Zoigê upland basin and its surrounding folded orogenic belts,crustal deformation and thickening in the northeastern margin of Tibetan Plateau,and decoupling and relaxing processes in the crust.The results indicate that a special 'Mesozoic basement' is formed of Triassic rocks with high density (2.65-2.75 g/cm3) and high velocity (5.6 km/s) in Zoigê basin.Songpan-Garze tectonic massif was transformed into two types of tectonic units with different crustal structures,i.e.,relatively stable Zoigê upland basin and active folded orogenic belts around the basin,in the course of the crustal material of Tibetan Plateau flowing eastward and obstructed by surrounding stable blocks.The thickening of the crust in the northeastern margin of Tibetan Plateau mainly occurred in the mid and lower crust,and the structure characterized by low velocities and multiple reflectors obviously appears in the folded orogenic belts around Zoigê basin.It implies that the mid and lower crust underwent a strong tectonic deformation in the folded orogenic areas.The thickness of the crust is about 50 km in Zoigê basin and the folded orogenic belts at the both southern and northern sides of Zoigê basin.The 'Mountain root' cannot be identified.It is inferred that during the later orogenic period the eastwards flowing deep materials moved clockwise along the relatively relaxing southern side around the eastern tectonic knot under the obstructing of surrounding rigid massifs,and it resulted in the strong stretching action of the folded orogenic belts around Zoigê basin. | JIA ShiXu,ZHANG XianKang,ZHAO JinRen,WANG FuYun,ZHANG ChengKe,XU ZhaoFan,PAN JiShun,LIU Zhi,PAN SuZhen & SUN GuoWei Geophysical Exploration Center,China Earthquake Administration,Zhengzhou 450002,China | 2010 | Science China Earth Sciences2010，53，2： | 11 |

| 7 | Metal Sealing Performance of Subsea X-tree Wellhead Connector Sealer显示文摘The metal sealing performance of subsea X-tree wellhead connectors is crucial for the safety and reliability of subsea X-trees. In order to establish the theoretical relation between metal sealing ring's contact stress and its structural parameters and working pressure, a mechanical analysis method for double-cone sealing of high pressure vessels is applied in analyzing the metal sealing ring under the condition of preload and operation. As a result, the formula of the unit sealing load for the metal sealing ring under operation with residual preload is shown in this paper, which ensures that the metal sealing ring has an excellent sealing effect and can prevent the metal sealing ring from yielding. Besides, while analyzing the sealing process of the metal sealing ring, the change rule of contact stress and working pressure is concluded here, putting forward that the structural parameters of the metal sealing ring are the major factors affecting the change rule. Finally, the analytical solution through theoretical analysis is compared with the simulation result through finite element analysis in a force feedback experiment, and both are consistent with each other, which fully verifies for the design and calculation theory on metal sealing ring's contact stress and its structural parameters and working pressure deduced in this paper. The proposed research will be treated as an applicable theory guiding the design of metal seal for subsea X-tree wellhead connectors. | ZHAO Honglin CHEN Rui LUO Xiaolan DUAN Menglan LU Yinghui FU Guowei TIAN Hongping YE Daohui | 2015 | Chinese Journal of Mechanical Engineering2015，28，3： | 9 |
| 8 | Geochemistry of the E-MORB type ophiolite and related volcanic rocks from the Wushan area, West Qinling显示文摘The mafic-ultramafic assemblages, which thrustthrust into the Wushan-Tangzang boundary fault as some blocks and outcropped in the Yuanyangzhen, Lijiahe, Lubangou and Gaojiahe area, consist mainly of meta-peridotites, gabbros and basalts. The meta-peridotites are characterized by high SiO2 and MgO contents, low ΣREE, as well as their chondrite-normalized rare earth element patterns show some similarities to that of middle oceanic meta-peridotite. The basalts from the Yuanyangzhen, Lijiahe and Lubangou area are characterized by relatively high TiO2 content, low Al2O3 content and Na2O>>K2O. Above all, it is the slight enrichment or flat REE distribution patterns and the unfractionated in HFS elements in the primitive-normalized trace elements distribution patterns that indicate these basalts are similar to that of the typical E-MORB. In comparison, the basalts from the Gaojiahe section are featured by depletion in Nb and Ta contents and enrichment in Th content which show that these were derived from an island-arc setting. From studies of the regional geology, petrology, geochemistry, geo- chronology and all above evidence, it can be suggested that the mafic-ultramafic rocks from the Wushan area are mainly dismembered E-MORB type ophiolite, which represent the fragments of the lithosphere of the Early-Paleozoic Qinling ocean. It is preferred that these rocks were formed in an initial mid-ocean ridge setting during the beginning stage of the oceanic basin spreading. This ophiolite together with the Gaojiahe island-arc basalts shows that there exists an ophiolitic mélange along the Wushan-Tangzang boundary fault, and marks the suture zone after the closure of the Qinling ocean in early Paleozoic. | DONG YunPeng ZHANG GuoWei YANG Zhao ZHAO Xia MA HaiYong YAO AnPing | 2007 | Science China Earth Sciences2007，50，z2： | 9 |
| 9 | A more consistent intraluminal rhesus monkey model of ischemic stroke显示文摘Endovascular surgery is advantageous in experimentally induced ischemic stroke because it causes fewer cranial traumatic lesions than invasive surgery and can closely mimic the pathophysiology in stroke patients. However, the outcomes are highly variable, which limits the accuracy of evaluations of ischemic stroke studies. In this study, eight healthy adult rhesus monkeys were randomized into two groups with four monkeys in each group: middle cerebral artery occlusion at origin segment(M1) and middle cerebral artery occlusion at M2 segment. The blood flow in the middle cerebral artery was blocked completely for 2 hours using the endovascular microcoil placement technique(1 mm × 10 cm)(undetachable), to establish a model of cerebral ischemia. The microcoil was withdrawn and the middle cerebral artery blood flow was restored. A reversible middle cerebral artery occlusion model was identified by hematoxylin-eosin staining, digital subtraction angiography, magnetic resonance angiography, magnetic resonance imaging, and neurological evaluation. The results showed that the middle cerebral artery occlusion model was successfully established in eight adult healthy rhesus monkeys, and ischemic lesions were apparent in the brain tissue of rhesus monkeys at 24 hours after occlusion. The rhesus monkeys had symptoms of neurological deficits. Compared with the M1 occlusion group, the M2 occlusion group had lower infarction volume and higher neurological scores. These experimental findings indicate that reversible middle cerebral artery occlusion can be produced with the endovascular microcoil technique in rhesus monkeys. The M2 occluded model had less infarction and less neurological impairment, which offers the potential for application in the field of brain injury research. | Bo Zhao Guowei Shang Jian Chen Xiaokun Geng Xin Ye Guoxun Xu Ju Wang Jiasheng Zheng Hongjun Li Fauzia Akbary Shengli Li Jing Lu Feng Ling Xunming Ji | 2014 | Neural Regeneration Research2014，9，23： | 6 |
| 10 | COR27 and COR28 encode nighttime repressors integrating Arabidopsis circadian clock and cold response显示文摘It was noted that circadian components function in plant adaptation to diurnal temperature cycles and freezing tolerance.Our genome-wide transcriptome analysis revealed that evening-phased COR27 and COR28 mainly repress the transcription of clockassociated evening genes PRR5,ELF4 and cold-responsive genes.Chromatin immunoprecipitation indicated that CCA1 is recruited to the site containing EE elements of COR27 and COR28 promoters in a temperaturedependent way.Further genetic analysis shows COR28 is essential for the circadian function of PRR9 and PRR7.Together,our results support a role of COR27 and COR28 as nighttime repressors integrating circadian clock and plant cold stress responses. | peng wang xuan cui chunsheng zhao liyan shi guowei zhang fenglong sun xiaofeng cao li yuan qiguang xie xiaodong xu | 2017 | Journal of Integrative Plant Biology2017，59，2： | 6 |
| 11 | SARS-CoV-2 promotes RIPK1 activation to facilitate viral propagation显示文摘Coronavirus disease 2019(COVID-19),caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),is the ongoing global pandemic that poses substantial challenges to public health worldwide.A subset of COVID-19 patients experience systemic inflammatory response,known as cytokine storm,which may lead to death.Receptor-interacting serine/threonine-protein kinase 1(RIPK1)is an important mediator of inflammation and cell death.Here,we examined the interaction of RIPK1-mediated innate immunity with SARS-CoV-2 infection.We found evidence of RIPK1 activation in human COVID-19 lung pathological samples,and cultured human lung organoids and ACE2 transgenic mice infected by SARS-CoV-2.Inhibition of RIPK1 using multiple smallmolecule inhibitors reduced the viral load of SARS-CoV-2 in human lung organoids.Furthermore,therapeutic dosing of the RIPK1 inhibitor Nec-1s reduced mortality and lung viral load,and blocked the CNS manifestation of SARS-CoV-2 in ACE2 transgenic mice.Mechanistically,we found that the RNA-dependent RNA polymerase of SARS-CoV-2,NSP12,a highly conserved central component of coronaviral replication and transcription machinery,promoted the activation of RIPK1.Furthermore,NSP12323L variant,encoded by the SARS-CoV-2 C14408T variant first detected in Lombardy,Italy,that carries a Pro323Leu amino acid substitution in NSP12,showed increased ability to activate RIPK1.Inhibition of RIPK1 downregulated the transcriptional induction of proinflammatory cytokines and host factors including ACE2 and EGFR that promote viral entry into cells.Our results suggest that SARS-CoV-2 may have an unexpected and unusual ability to hijack the RIPK1-mediated host defense response to promote its own propagation and that inhibition of RIPK1 may provide a therapeutic option for the treatment of COVID-19. | Gang Xu Ying Li Shengyuan Zhang Haoran Peng Yunyun Wang Dekang Li Taijie Jin Zhuohao He Yilun Tong Chunting Qi Guowei Wu Kangyun Dong Jizhou Gou Yang Liu Tongyang Xiao Jing Qu Liang Li Liang Liu Ping Zhao Zheng Zhang Junying Yuan | 2021 | Cell Research2021，31，12： | 6 |
| 12 | Activation of STAT3 stimulates AHSP expression in K562 cells显示文摘Studies on the chaperone proteinα-hemoglobin stabilizing protein(AHSP)reveal that abundant AHSP in erythroid cells enhance the cells’tolerance to oxidative stress imposed by excessα-hemoglobin in pathological conditions.However,the potential intracellular modulation of AHSP expression itself in response to oxidative stress is still unknown.The present study examined the effect and molecular mechanism of STAT3,an oxidative regulator,on the expression of AHSP.AHSP expression increased in K562 cells upon cytokine IL-6-induced STAT3 activation and decreased in STAT3 knock-down K562 cells.Regulation of AHSP in oxidative circumstance was then examined inα-globin-overloaded K562 cells,and real-time PCR showed strengthened expression of both AHSP and STAT3.ChIP analysis showed binding of STAT3 to AHSP promoter and binding was significantly augmented with IL6 stimulation and uponα-globin overexpression.Dual luciferase reporter assays of the wildtype and mutated SB3 element,an IL-6RE site,in the AHSP promoter in K562 cells highlighted the direct regulatory effect of STAT3 on AHSP gene.Finally,direct binding of STAT3 to SB3 site of AHSP promoter was confirmed with EMSA assays.Our work reveals an adaptive AHSP regulation mediated by the redox-sensitive STAT3 signaling pathway,and provides clues to the therapeutic strategy for AHSP enhancement. | CAO Cong ZHAO GuoWei YU Wei XIE XueMin WANG WenTian YANG RuiFeng LV Xiang LIU DePei | 2014 | Science China(Life Sciences)2014，57，5： | 5 |
| 13 | Coevolution of brachiopod paleobiogeography and tectonopaleogeography during the late Paleozoic in Central Asia显示文摘Patterns of brachiopod paleobiogeographic regionalization in Central Asia reveal a coevolution between brachiopod paleobiogeography and tectonopaleogeography during the Early Devonian,Early Carboniferous,Late Carboniferous,Early Permian,and Middle Permian.The coevolutionary relationship reasonably accounts for the formation mechanisms of brachiopod paleobiogeography in this region,and also provides a basis for studies on the location and configuration of oceans and plates(blocks)during the late Paleozoic in Central Asia. | WANG ChengWen ZHAO GuoWei LI Ning ZONG Pu | 2013 | Science China Earth Sciences2013，56，12： | 5 |
| 14 | Stratigraphic framework of late Paleozoic in northeastern China显示文摘Late Paleozoic strata in northeastern China are distributed in a zonal pattern around the old-land on the Jiamusi-Mongolia Block.They are composed of active deposits in the regular distributed tectonic lithofacies zones.This indicates that the late Paleozoic strata belong to continental margin deposits.According to the strong conformability of the sedimentary strata in the same continental margin and distinct differences among the three continental margins,three stratigraphical regions of the Jiamusi-Mongolia Stratigraphical Province are recognized along the northern,southern and eastern margins of the Jiamusi-Mongolia Block,named respectively as Xing'an Stratigraphical Region,Inner Mongolia grass--Songhua River Stratigraphical Region and Baoqing--Hunchun Stratigraphical Region.Due to the characteristics of continental margin deposits and active sediments,the strata can be correlated on the level of formation by the methods of analysing the rock association in the same stratigraphic region.Therefore,some revisions of the lithological formations of the late Paleozoic strata in northeastern China have been made,and a new chart of lithostratigraphic correlation has been proposed.Furthermore,the present stratigraphic framework is setting on the International Stratigraphic Chart on the level of stage,after comprehensive researches to lithostratigraphy,biostratigraphy and chronostratigraphy,especially the conodont biostratigraphy and isotopic ages of volcanic rocks obtained in recent years. | WANG Chengwen LI Ning SUN Yuewu ZONG Pu ZHAO Guowei LIU Hui MA Xiaoqin | 2013 | Global Geology2013，16，1： | 4 |
| 15 | Analysis of profit models for cross-border power interconnection projects显示文摘With the increasing demand worldwide for power grid interconnection,a growing number of related projects are under planning or construction.Despite the rapid growth of cross-border interconnection projects,the systematic research on profit models for these projects is insufficient.This paper first analyzes the profit sources of interconnection projects.Based on the analysis results,profit models are considered under different regulatory systems for three types of crossborder interconnection projects:fully market-oriented,semi-marketization,and fully supervised.Finally,measures for increasing the profitability and sustainable development of power interconnection projects are proposed. | Jing Li Guowei Gao Li Ma Tian Zhao Haoyuan Qu Fu Chen | 2019 | Global Energy Interconnection2019，2，5： | 4 |
| 16 | Numerical Simulation of Multi-Directional Random Wave Transformation in a Yacht Port显示文摘This paper extends a prediction model for multi-directional random wave transformation based on an energy balance equation by Mase with the consideration of wave shoaling, refraction, diffraction, reflection and breaking. This numerical model is improved by 1) introducing Wen's frequency spectrum and Mitsuyasu's directional function, which are more suitable to the coastal area of China; 2) considering energy dissipation caused by bottom friction, which ensures more accurate results for large-scale and shallow water areas; 3) taking into account a non-linear dispersion relation. Predictions using the extended wave model are carried out to study the feasibility of constructing the Ai Hua yacht port in Qingdao, China, with a comparison between two port layouts in design. Wave fields inside the port for different incident wave directions, water levels and return periods are simulated, and then two kinds of parameters are calculated to evaluate the wave conditions for the two layouts. Analyses show that Layout I is better than Layout II. Calculation results also show that the harbor will be calm for different wave directions under the design water level. On the contrary, the wave conditions do not wholly meet the requirements of a yacht port for ship berthing under the extreme water level. For safety consideration, the elevation of the breakwater might need to be properly increased to prevent wave overtopping under such water level. The extended numerical simulation model may provide an effective approach to computing wave heights in a harbor. | JI Qiaoling DONG Sheng ZHAO Xizeng ZHANG Guowei | 2012 | Journal of Ocean University of China2012，11，3： | 3 |
| 17 | Variation of crystal orientation during epitaxial growth of dendrites by laser deposition显示文摘A nickel-based superalloy was deposited onto a single crystal substrate based on epitaxial laser metal forming(E-LMF). The microstructure development in two depositions has been researched. For the first time, the crystal orientation of dendrites varying beyond 20° was found when the dendrites deflected in deposition. In addition, a new grain boundary was found between different orientation dendrites in a grain, and the detected grain boundary angle was 23°. The result shows that flowing field in laser pool is responsible for this phenomenon. | Guowei Wang Jingjing Liang Yizhou Zhou Libin Zhao Tao Jin Xiaofeng Sun | 2018 | Journal of Materials Science & Technology2018，34，4： | 3 |
| 18 | Controlling plasmon‐exciton interactions through photothermal reshaping显示文摘We investigated the plasmon-exciton interactions in an individual gold nanorod(GNR)with monolayer MoS2 at room temperature with the single-particle spectroscopy technique.To control the plasmon-exciton interaction,we tuned the local surface plasmon resonance of an individual GNR in-situ by employing the photothermal reshaping effect.The scattering spectra of the GNR-MoS2 hybrids exhibited two dips at the frequencies of the A and B excitons of monolayer MoS2,which were caused by the plasmon-induced resonance energy transfer effect.The resonance energy transfer rate increased when the surface plasmon resonance of the nanorod matched well with the exciton transition energy.Also,we demonstrated that the plasmon-enhanced fluorescence process dominated the photoluminescence of the GNR-MoS2 hybrid.These results provide a flexible way to control the plasmon-exciton interaction in an all-solid-state operating system at room temperature. | Aiqin Hu Shuai Liu Jingyi Zhao Te Wen Weidong Zhang Qihuang Gong Yongqiang Meng Yu Ye Guowei Lu | 2020 | Opto-Electronic Advances2020，3，1： | 2 |

| 20 | Effect of Soil C,N and P Stoichiometry on Soil Organic C Fractions After Afforestation显示文摘Afforestation is recognized as an important driving force for soil organic C(SOC) dynamics and soil element cycling.To evaluate the relationships between soil C:N:P stoichiometry and SOC fractions,soil C:N:P stoichiometry distributions at 0–200 cm soil depths were analyzed and the contents of SOC fractions were evaluated in 9 typical land-use systems on the Loess Plateau of China.The contents of light fraction organic C,particulate organic C(>53,53–2 000,and>2 000 μm),labile organic C,microbial biomass C,and dissolved organic C decreased with increasing soil depth and were higher in afforested soil than in slope cropland soil.Compared with the slope cropland,different vegetation types influenced soil C:N,C:P,and N:P ratios,especially when C:P and N:P ratios were significantly higher(P<0.05).Moreover,SOC fractions at the 0–10 and 10–40 cm depths were particularly affected by soil C:P ratio,whereas those at the 40–100 and 100–200 cm soil depths were significantly affected(P<0.05) by soil N:P ratio.These results indicate that changes in SOC fractions are largely driven by soil C:P and N:P ratios at different soil depths after afforestation. | ZHAO Fazhu ZHANG Lu SUN Jiao REN Chengjie HAN Xinhui YANG Gaihe PANG Guowei BAI Hongying WANG Jun | 2017 | Pedosphere2017，27，4： | 1 |
