4Geological Guided Tomography Inversion Based on Fault Constraint and Its Application显示文摘Fault block reservoirs are one of the main types of hydrocarbon reservoirs found in offshore basins,and they are widely distributed within the Mesozoic and Cenozoic basins of the northern South China Sea.Conventional seismic profiles of complex fault areas often contain obvious fragmentation and distortion of seismic events that is corresponding to geological structure under the fault.This phenomenon is known as a fault shadow;it occurs in relation to rapid changes in velocity near the fault that deviate the ray path of waves,and it seriously affects the ability to determine the geological structure and subsequently evaluate the reserves of fault reservoirs.In the current conventional tomography inversion method,the velocity model is over-smoothed,which results in distortion of the reflection layer under the fault.Based on the velocity tomography inversion of imaging gathers method and the concept of regularization,this paper first introduces the anisotropy Gauss regularization operator.A high-resolution tomography inversion method is then developed,and the fault-controlled geological guidance is constrained.This technology is then applied to a complex fault block reservoir basin in the South China Sea,and the results show that it can significantly solve the problem of fault shadow imaging and determine the geological structures in the target area.The newly developed method thus has very good application prospects.LI Sanfu ZHANG Xiaobo DAN Zhiwei SUN Bo SONG Peng SUN Leiming FANG Zhongyu LI Lie 2021Journal of Ocean University of China2021,20,6:0
5Quantum optical devices based on four-wave mixing in hot rubidium vapor显示文摘In this paper,we briefly review the recent experimental progresses in quantum optics based on four-wave mixing(FWM) processes in hot rubidium vapor,particularly our two recent experiments in quantum information.We have experimentally produced strong quantum correlations between three bright beams generated by two cascaded FWM processes.The intensity difference squeezing with the cascaded system is enhanced to(-7.0±0.1)d B from the(-5.5±0.1)d B/(4.5±0.1)d B with only one FWM process.Also,this system can be easily extended to multiple modes using multiple FWM processes.Besides,we have also successfully realized a cascade all-optical transistor(AOT),which is driven by a very weak light beam about 800 photons in total.The required probe power for achieving a switching efficiency of 50% can be as low as 180 p W,and it can manipulate a light beam with power of 5.0×106 times more,which proves the cascade of the AOT.Both experiments may find wide applications in quantum information and optical communication.FANG YaMi QIN ZhongZhong WANG HaiLong CAO LeiMing XIN Jun FENG JingLiang ZHANG WeiPing JING JieTai 2015Science China(Physics,Mechanics & Astronomy)2015,58,6:0
6Pressure-induced disordering of site occupation in iron–nickel nitrides显示文摘Controlled disordering of substitutional and interstitial site occupation at high pressure can lead to important changes in the structural and physical properties of iron–nickel nitrides.Despite important progress that has been achieved,structural characterization of ternary Fe–Ni–N compounds remains an open problem owing to the considerable technical challenges faced by current synthetic and structural approaches for fabrication of bulk ternary nitrides.Here,iron–nickel nitride samples are synthesized as spherical-like bulk materials through a novel highpressure solid-state metathesis reaction.By employing a wide array of techniques,namely,neutron powder diffraction,Rietveld refinement methods combined with synchrotron radiation angle-dispersive x-ray diffraction,scanning electron microscopy/energy dispersive x-ray spectroscopy,and transmission electron microscopy,we demonstrate that high-temperature and high-pressure confinement conditions favor substitutional and interstitial site disordering in ternary iron–nickel nitrides.In addition,the effects of interstitial nitrogen atoms and disorderly substituted nickel atoms on the elastic properties of the materials are discussed.Binbin Wu Li Lei Feng Zhang Qiqi Tang Shan Liu Meifang Pu Duanwei He Yuanhua Xia Leiming Fang Hiroaki Ohfuji Tetsuo Irifune 2021Matter and Radiation at Extremes2021,6,3:0
7A cost-effective ts CUT&Tag method for profiling transcription factor binding landscape显示文摘Knowledge of the transcription factor binding landscape(TFBL)is necessary to analyze gene regulatory networks for important agronomic traits.However,a low-cost and high-throughput in vivo chromatin profiling method is still lacking in plants.Here,we developed a transient and simplified cleavage under targets and tagmentation(tsCUT&Tag)that combines transient expression of transcription factor proteins in protoplasts with a simplified CUT&Tag without nucleus extraction.Our tsCUT&Tag method provided higher data quality and signal resolution with lower sequencing depth compared with traditional ChIP-seq.Furthermore,we developed a strategy combining tsCUT&Tag with machine learning,which has great potential for profiling the TFBL across plant development.Leiming Wu Zi Luo Yanni Shi Yizhe Jiang Ruonan Li Xinxin Miao Fang Yang Qing Li Han Zhao Jiquan Xue Shutu Xu Tifu Zhang Lin Li 2022Journal of Integrative Plant Biology2022,64,11:0
