| 1 | Variations of pore water sulfate gradients in sediments as indicator for underlying gas hydrate in Shenhu Area, the South China Sea显示文摘Shenhu Area is one of the most promising areas for gas hydrate exploration in the northern South China Sea (SCS). Pore water sulfate gradient, sulfate-methane interface (SMI) depth, and sulfate flux were analyzed at 53 sites in this area. SO42 gradient ranges between 0.33 and 4.43 mmol L-1 m-1 . SMI depths are from 7.7 to 87.9mbsf. Sulfate flux varies between 2.0 and 26.9 mmol m-2 yr-1 , with a mean of 11.7 mmol m-2 yr-1 . Correlation coefficient between SMI depth and methane flux for the 53 sites is 0.80, implying that methane flux regulates the rate of anaerobic methane oxidation (AMO), SMI depth, and sulfate flux. Twelve anomalous fields with high methane flux and steep sulfate gradients were recognized. Bottom simulating reflector (BSR) is distributed mainly in areas where SMI depth is less than 50 mbsf or places with sulfate flux larger than 3.5 mmol m-2 yr-1 . It is suggested that the Baiyun Sag and the Southern Uplift are potential areas for gas hydrate exploration. | WU LuShan YANG ShengXiong LIANG JinQiang SU Xin FU ShaoYing SHA ZhiBin YANG Tao | 2013 | Science China Earth Sciences2013，56，4： | 24 |
| 2 | The Dihedral Angle and Intersection Processes of a Conjugate Strike-Slip Fault System in the Tarim Basin, NW China显示文摘Recent studies, focused on dihedral angles and intersection processes, have increased understandings of conjugate fault mechanisms. We present new 3-D seismic data and microstructural core analysis in a case study of a large conjugate strike-slip fault system from the intracratonic Tarim Basin, NW China. Within our study area, 'X' type NE and NW trending faults occur within CambrianOrdovician carbonates. The dihedral angles of these conjugate faults have narrow ranges, 19° to 62° in the Cambrian and 26° to 51° in the Ordovician, and their modes are 42° and 44° respectively. These data are significantly different from the ~60° predicted by the Coulomb fracture criterion. It is concluded that:(1) The dihedral angles of the conjugate faults were not controlled by confining pressure, which was low and associated with shallow burial;(2) As dihedral angles were not controlled by pressure they can be used to determine the shortening direction during faulting;(3) Sequential slip may have played an important role in forming conjugate fault intersections;(4) The conjugate fault system of the Tarim basin initiated as rhombic joints; these subsequently developed into sequentially active 'X' type conjugate faults; followed by preferential development of the NW-trending faults; then reactivation of the NE trending faults. This intact rhombic conjugate fault system presents new insights into mechanisms of dihedral angle development, with particular relevance to intracratonic basins. | WU Guanghui YUAN Yajuan HUANG Shaoying Thomas Matthew Vandyk XIAO Yang CAI Quan LUO Bingxu | 2018 | Acta Geologica Sinica(English Edition)2018，92，1： | 19 |
| 3 | Coupled carbon and sulfur isotope behaviors and other geochemical perspectives into marine methane seepage显示文摘Methane seepage is the signal of the deep hydrocarbon reservoir. The determination of seepage is significant to the exploration of petroleum, gas and gas hydrate. The seepage habits microbial and macrofaunal life which is fueled by the hydrocarbons, the metabolic byproducts facilitate the precipitation of authigenic minerals. The study of methane seepage is also important to understand the oceanographic condition and local ecosystem. The seepage could be active or quiescent at different times. The geophysical surveys and the geochemical determinations reveal the existence of seepage. Among these methods, only geochemical determination could expose message of the dormant seepages. The active seepage demonstrates high porewater methane concentration with rapid SO_4^(2–) depleted, low H_2S and dissolved inorganic carbon(DIC), higher rates of sulfate reduction(SR) and anaerobic oxidation of methane(AOM). The quiescent seepage typically develops authigenic carbonates with specific biomarkers, with extremely depleted ~13C in gas, DIC and carbonates and with enriched ~34S sulfate and depleted ~34S pyrite. The origin of methane, minerals precipitation, the scenario of seepage and the possible method of immigration could be determined by the integration of solutes concentration, mineral composition and isotopic fractionation of carbon, sulfur. Numerical models with the integrated results provide useful insight into the nature and intensity of methane seepage occurring in the sediment and paleooceanographic conditions. Unfortunately, the intensive investigation of a specific area with dormant seep is still limit. Most seepage and modeling studies are site-specific and little attempt has been made to extrapolate the results to larger scales. Further research is thus needed to foster our understanding of the methane seepage. | LIU Lihua FU Shaoying ZHANG Mei GUAN Hongxiang WU Nengyou | 2017 | Acta Oceanologica Sinica2017，36，6： | 2 |

| 8 | A venom protein of ectoparasitoid Pachycrepoideus vindemiae, PvG6PDH, contributes to parasitism by inhibiting host glucose-6-phosphate metabolism显示文摘To achieve successful development,female parasitoids,while laying eggs,introduce various virulence factors,mainly venoms,into host insects to manipulate their physiology.Although numerous studies have been conducted to characterize the components of venoms that regulate host immune responses,few systematic investigations have been conducted on the roles of venom proteins in host metabolic regulation.In this investigation,we characterized a novel venom protein in Pachycrepoideus vindemiae called glucose-6-phosphate dehydrogenase(PvG6PDH)and showed it has a vital role in regulating host carbohydrate metabolism.PvG6PDH encodes 510 amino acids and features a signal peptide and two conserved“G6PDH”domains.Multiple sequence alignment showed it has high amino acid identity with G6PDH from other pteromalids,and quantitative polymerase chain reaction analysis and immunofluorescent staining demonstrated a significantly higher expression of PvG6PDH in the venom apparatus compared with the carcass.We report that PvG6PDH contributes to parasitism by inhibiting the glucose-6-phosphate(G6P)metabolism of host Drosophila melanogaster,as demonstrated by PvG6PDH injection and RNA interference analysis.Further tests revealed that the accumulation of host G6P was caused by the transcriptional inhibition of G6P-metabolism-related genes.These findings greatly contribute to our understanding of venom-mediated host metabolic regulation,further laying the foundation for the development of venom proteins as biological agents for pest control. | Lei Yang Liming Qiu Qi Fang Shaoying Wu Gongyin Ye | 2022 | Insect Science2022，29，2： | 0 |
| 9 | Performance of a Global Spectral Model with Dry Air-Mass and Total Air-Mass Conserving Dynamical Cores:A Case Study of the July 2021 Henan Extreme Rainfall Event显示文摘This study investigates the effects of the assumption on the types of air-mass conservation prescribed in numerical models.First,predictions of the July 2021(“21.7”)Henan extreme rainfall event from the Integrated Forecast System(IFS)at ECMWF were compared with those from the Yin-He Global Spectral Model(YHGSM),which is a global spectral model with total air-mass conservation(TMC)and dry air-mass conservation(DMC)options.Then,a sensitivity test between simulations from the YHGSM adopting TMC and DMC was conducted.The results show that both the IFS and YHGSM predicted relatively well the 24-h rainfall amount less than 100 mm day−1 on 20 and 21 July 2021 at lead times of 84,60,and 36 h.For heavy precipitation exceeding 100 mm day−1,however,both models obviously underestimated the daily rainfall amount on 20 July 2021,but the YHGSM produced more precise and stable precipitation forecasts on these two days than the IFS,especially the maximum 24-h precipitation amount,with better consistency at lead times of 84,60,and 36 h.These differences are further examined in the sensitivity test.Predictions from the YHGSM with DMC show rainfall distributions and daily rainfall amounts closer to the observations at longer lead times.It is inferred that considering sources or sinks of total water in dynamical cores with DMC may have positive feedback for the precise prediction of condensates.For extreme rainfall events,the high local loss of total water may have caused a loss of the atmospheric mass,leading to an additional decrease in surface pressure.Subsequently,the unbalanced pressure gradient force enhances the cyclonic rotation of surface wind and strengthens convergence in the lower troposphere,which in turn further strengthens the vertical velocity,circularly contributing to the enhanced precipitation if the water vapor condition is favorable. | Xiangrong YANG Weimin ZHANG Jun PENG Shaoying LI Jianping WU | 2023 | Journal of Meteorological Research2023，37，1： | 0 |
| 10 | Electrical properties of Si/Si bonded wafers based on an amorphous Ge interlayer显示文摘An amorphous Ge(a-Ge) intermediate layer is introduced into the Si bonded interface to lower the annealing temperature and achieve good electrical characteristics. The interface and electrical characteristics of nSi/n-Si and p-Si/n-Si junctions manufactured by low-temperature wafer bonding based on a thin amorphous Ge are investigated. It is found that the bubble density tremendously decreases when the a-Ge film is not immersed in DI water. This is due to the decrease of the –OH groups. In addition, when the samples are annealed at 400 °C for20 h, the bubbles totally disappear. This can be explained by the appearance of the polycrystalline Ge(absorption of H_2) at the bonded interface. The junction resistance of the n-Si/n-Si bonded wafers decreases with the increase of the annealing temperature. This is consistent with the recrystallization of the a-Ge when high-temperature annealing is conducted. The carrier transport of the Si-based PN junction annealed at 350 °C is consistent with the trap-assisted tunneling model and that annealed at 400 °C is related to the carrier recombination model. | Shaoming Lin Shaoying Ke Yujie Ye Donglin Huang Jinyong Wu Songyan Chen Cheng Li Jianyuan Wang Wei Huang | 2018 | Journal of Semiconductors2018，39，11： | 0 |
| 11 | Theoretical study of a group IV p–i–n photodetector with a flat and broad response for visible and infrared detection显示文摘We report a theoretical study of a broadband Si/graded-SiGe/Ge/Ge0.9Sn0.1 p–i–n photodetector with a flat response based on modulating thickness of the layers in the active region.The responsivity of the photodetector is about 0.57 A/W in the range of 700 to 1800 nm.This structure is suitable for silicon-based epitaxial growth.Annealing is technically applied to form the graded-SiGe.The photodetector reaches a cut-off wavelength at^2300 nm and a low dark-current density under 3 V reverse bias about 0.17 mA/cm^2 is achieved theoretical at room temperature.This work is of great significance for silicon-based detection and communication,from visible to infrared. | Jinyong Wu Donglin Huang Yujie Ye Jianyuan Wang Wei Huang Cheng Li Songyan Chen Shaoying Ke | 2020 | Journal of Semiconductors2020，41，12： | 0 |
| 12 | Crustal Structure of the Chuan-Dian Block Revealed by Deep Seismic Sounding and its Implications for the Outward Expansion of the East Tibetan Plateau显示文摘The Chuan-Dian Block(CDB)is located in the southeastern margin of the Tibetan Plateau,with a complex geological structure and active regional faults.The present tectonic condition with strong crustal deformation is closely related to the ongoing collision of the India and Eurasia plates since 65 Ma.The study of the crustal structure of this area is key to revealing the evolution and deep geodynamics of the lateral collision zone of the Tibetan Plateau.Deep seismic sounding is the most efficient method with which to unravel the velocity structure of the whole crust.Since the 1980s,19 deep seismic sounding profiles have been captured within the CDB area.In this study,we systematically integrate the research results of the 19 profiles in this area,then image the 3D crustal velocity,by sampling with a 5 km spacing and 2D/3D Kriging interpolation.The results show the following.(1)The Moho depth in the study area deepens from 30 km in the south to 66 km in the north,whereas there is no apparent variation from west to east.The Pn wave velocity is higher in stable tectonic units,such as 7.95 km/s in the Lanping-Simao block and 7.94 km/s in the western margin of the Yangtze block,than in active or mobile tectonic units,such as 7.81 km/s in the Baoshan block,7.72 km/s in the Tengchong block and 7.82 km/s in the Zhongdian block.(2)The crustal nature of the Tengchong block,the northern Lanping-Simao block and the Zhongdian block reflects a type of orogenic belt,having relatively strong tectonic activities,whereas the crustal nature of the central Lanping-Simao block and the western margin of the Yangtze block represents a type of platform.The different features of the upper-middle crust velocity,Moho depth and Pn wave velocity to both sides of the Red River fault zone and the Xianshuihe fault zone,reflect that they are clearly ultra-crustal.(3)Based on the distribution of the low velocity zones in the crust,the crustal material of the Tibetan Plateau is flowing in a NW–SE direction to the north of 26°N and to the west of 101°E,then diverting to flowing eastwards to the east of 101°E. | XIONG Xiaosong WANG Guan LI Qiusheng LU Zhanwu GAO Rui FENG Shaoying WU Guowei | 2022 | Acta Geologica Sinica(English Edition)2022，96，6： | 0 |
| 13 | Effects of a Dry-Mass Conserving Dynamical Core on the Simulation of Tropical Cyclones显示文摘The accurate forecasting of tropical cyclones(TCs)is a challenging task.The purpose of this study was to investigate the effects of a dry-mass conserving(DMC)hydrostatic global spectral dynamical core on TC simulation.Experiments were conducted with DMC and total(moist)mass conserving(TMC)dynamical cores.The TC forecast performance was first evaluated considering 20 TCs in the West Pacific region observed during the 2020 typhoon season.The impacts of the DMC dynamical core on forecasts of individual TCs were then estimated.The DMC dynamical core improved both the track and intensity forecasts,and the TC intensity forecast improvement was much greater than the TC track forecast improvement.Sensitivity simulations indicated that the DMC dynamical core-simulated TC intensity was stronger regardless of the forecast lead time.In the DMC dynamical core experiments,three-dimensional winds and warm and moist cores were consistently enhanced with the TC intensity.Drier air in the boundary inflow layer was found in the DMC dynamical core experiments at the early simulation times.Water vapor mixing ratio budget analysis indicated that this mainly depended on the simulated vertical velocity.Higher updraft above the boundary layer yielded a drier boundary layer,resulting in surface latent heat flux(SLHF)enhancement,the major energy source of TC intensification.The higher DMC dynamical core-simulated updraft in the inner core caused a higher net surface rain rate,producing higher net internal atmospheric diabatic heating and increasing the TC intensity.These results indicate that the stronger DMC dynamical coresimulated TCs are mainly related to the higher DMC vertical velocity. | Shaoying LI Jun PENG Weimin ZHANG Jianping WU Qiang YAO Xiangrong YANG Tengling LUO | 2023 | Advances in Atmospheric Sciences2023，40，3： | 0 |
