2Retrieving Drill Bit Seismic Signals Using Surface Seismometers显示文摘Seismic while drilling(SWD) is an emerging borehole seismic imaging technique that uses the downhole drill-bit vibrations as seismic source.Without interrupting drilling,SWD technique can make near-real-time images of the rock formations ahead of the bit and optimize drilling operation,with reduction of costs and the risk of drilling.However,the signal to noise ratio(SNR) of surface SWD-data is severely low for the surface acquisition of SWD data.Here,we propose a new method to retrieve the drill-bit signal from the surface data recorded by an array of broadband seismometers.Taking advantages of wavefield analysis,different types of noises are identified and removed from the surface SWD-data,resulting in the significant improvement of SNR.We also optimally synthesize seismic response of the bit source,using a statistical cross-coherence analysis to further improve the SNR and retrieve both the drill-bit direct arrivals and reflections which are then used to establish a reverse vertical seismic profile(RVSP) data set for the continuous drilling depth.The subsurface images derived from these data compare well with the corresponding images of the three-dimension surface seismic survey cross the well.Linfei Wang Huaishan Liu Siyou Tong Yanxin Yin Lei Xing Zhihui Zou Xiugang Xu 2015Journal of Earth Science2015,26,4:2

4Shallow Water Body Data Processing Based on the Seismic Oceanography显示文摘Physical properties of sea water,such as salinity,temperature,density and acoustic velocity,could be demarcated through degradation of energy caused by water absorption,attenuation and other factors.To overcome the challenging difficulties in the quick monitoring of these physical properties,we have explored the high resolution marine seismic survey to instantly characterize them.Based on the unique wavefield propagating in the sea water,we have developed a new approach to suppress the noise caused by the shallow sea water disturbance and obtain useful information for estimating the sea water structure.This approach improves seismic data with high signal-to-noise ratio and resolution.The seismic reflection imaging can map the sea water structure acoustically.Combined with the knowledge of local water body structure profile over years,the instant model for predicting the sea water properties could be built using the seismic data acquired from the specially designed high precision marine seismic acquisition.This model can also be updated with instant observation and the complete data processing system.The present study has the potential value to many applications,such as 3D sea water monitoring,engineering evaluation,geological disaster assessment and environmental assessment.LIU Huaishan HU Yi YIN Yanxin WANG Linfei TONG Siyou MA Hai 2013Journal of Ocean University of China2013,12,3:2

9High-pressure investigations on the isostructural phase transition and metallization in realgar with diamond anvil cells显示文摘The high-pressure structural,vibrational and electrical properties for realgar were investigated by in-situ Raman scattering and electrical conductivity experiments combined with first-principle calculations up to~30.8 GPa.It was verified that realgar underwent an isostructural phase transition at~6.3 GPa and a metallization at a higher pressure of~23.5 GPa.The isostructural phase transition was well evidenced by the obvious variations of Raman peaks,electrical conductivity,crystal parameters and the As–S bond length.The phase transition of metallization was in closely associated with the closure of bandgap rather than caused by the structural phase transition.And furthermore,the metallic realgar exhibited a relatively low compressibility with the unit cell volume V_(0)=718.1.4Å^(3)and bulk modulus B_(0)=36.1 GPa.Linfei Yang Lidong Dai Heping Li Haiying Hu Meiling Hong Xinyu Zhang Pengfei Liu 2021Geoscience Frontiers2021,12,2:1
10Phase Characteristic Analysis of Continuous Depth Air-Gun Source Wavelet显示文摘Air guns are important sources for marine seismic exploration. Far-field wavelet of air gun arrays, as a necessary parameter for pre-stack processing and source models, plays an important role during marine seismic data processing and interpretation. When an air gun fires, it generates a series of air bubbles. Similar to onshore seismic exploration, the water forms a plastic fluid near the bubble; the farther the air gun is located from the measurement, the more steady and more accurately represented the wavelet will be. In practice, hydrophones should be placed more than 100 m from the air gun; however, traditional seismic cables cannot meet this requirement. On the other hand, vertical cables provide a viable solution to this problem. This study uses a vertical cable to receive wavelets from 38 air guns and data are collected offshore Southeast Qiong, where the water depth is over 1000 m. In this study, the wavelets measured using this technique coincide very well with the simulated wavelets and can therefore represent the real shape of the wavelets. This experiment fills a technology gap in China.XING Lei LIU Huaishan ZHENG Xilai LIU Xueqin ZHANG Jin WANG Linfei ZOU Zhihui XU Yiming 2016Journal of Ocean University of China2016,15,5:1
11Functional divergence of oligoadenylate synthetase 1(OAS1)proteins in Tetrapods显示文摘OASs play critical roles in immune response against virus infection by polymerizing ATP into 2-5 As,which initiate the classical OAS/RNase L pathway and induce degradation of viral RNA.OAS members are functionally diverged in four known innate immune pathways(OAS/RNase L,OASL/IRF7,OASL/RIG-I,and OASL/cGAS),but how they functionally diverged is unclear.Here,we focus on evolutionary patterns and explore the link between evolutionary processes and functional divergence of Tetrapod OAS1.We show that Palaeognathae and Primate OAS1 genes are conserved in genomic and protein structures but differ in function.The former(i.e.,ostrich)efficiently synthesized long 2-5 A and activated RNase L,while the latter(i.e.,human)synthesized short 2-5 A and did not activate RNase L.We predicted and verified that two in-frame indels and one positively selected site in the active site pocket contributed to the functional divergence of Palaeognathae and Primate OAS1.Moreover,we discovered and validated that an in-frame indel in the C-terminus of Palaeognathae OAS1 affected the binding affinity of ds RNA and enzymatic activity,and contributed to the functional divergence of Palaeognathae OAS1 proteins.Our findings unravel the molecular mechanism for functional divergence and give insights into the emergence of novel functions in Tetrapod OAS1.Xiaoxue Wang Jiaxiang Hu Linfei Song Enguang Rong Chenghuai Yang Xiaoyun Chen Juan Pu Honglei Sun Chuze Gao David WBurt Jinhua Liu Ning Li Yinhua Huang 2022Science China(Life Sciences)2022,65,7:1
12Effects of childhood trauma on aggressive behaviors andhippocampal function:the modulation of COMT haplotypes显示文摘Background:Aggression is a commonly hostile behavior linked to the hippocampal activity.Childhood trauma(CT)exposure has been associated with altered sensitization of the hypothalamic-pituitary-adrenal(HPA)axis and hippocampal volumewhich could increase violent aggressive behaviors.Additionally,Catechol-O-methyltransferase(COMT),the major dopamine metabolism enzyme,is impli-cated in stress responsivity,including aggression.Hence,CT exposure may affect aggression through the effect on the hippocampal function,which might also be modulated by the COMT variations.Objectives:This study examined whether both CT and haplotypes of COMT moderate hippocampal function and thus affect human aggressive behavior.Methods:We obtained bilateral hippocampal functional connectivity maps using resting state functional magnetic resonance imag-ing(MRI)data.COMT haplotype estimation was performed using Haploview 4.2 and PHASE 2.1.Then we constructed a moderated mediation model to study the effect of the CTQ×COMT on aggressive behavior.Results:Three major haplotypes were generated from thirteen single nucleotide polymorphisms(SNPs)within the COMT gene and formed three haplotypes corresponding to high,medium,and low enzymatic activity of COMT.The results showed interactive re-lationships between the Childhood Trauma Questionnaire(CTQ)and COMT with respect to the functional connectivity(FC)of the bilateral hippocampus(HIP)-orbital frontal cortex(OFC).Specifically,CT experience predicted lower negative HIP-OFC coupling in the APS and HPS haplotypes corresponding to the medium and high enzymatic activity of COMT,but greater FC in the LPS haplotypes corresponding to the low enzymatic activity.We also observed a conditional mediation effect of the right HIP-OFC coupling in the link between COMT and aggressive behavior that was moderated by CT experience.Conclusions:These results suggest that CT and COMT have a combined effect on aggressive behavior through hippocampal function.This mediation analysis sheds light on the influence of childhood experience on aggressive behavior in different genetic backgrounds.Chao Wang Linfei Zhu Wenyu Zheng Hanyuzhu Peng Jiaojian Wang Yue Cui Bing Liu Tianzi Jiang 2023Psychoradiology2023,3,1:0
13Shallowing interfacial carrier trap in transition metal dichalcogenide heterostructures with interlayer hybridization显示文摘With the unique properties,layered transition metal dichalcogenide(TMD)and its heterostructures exhibit great potential for applications in electronics.The electrical performance,e.g.,contact barrier and resistance to electrodes,of TMD heterostructure devices can be significantly tailored by employing the functional layers,called interlayer engineering.At the interface between different TMD layers,the dangling-bond states normally exist and act as traps against charge carrier flow.In this study,we propose a technique to suppress such carrier trap that uses enhanced interlayer hybridization to saturate dangling-bond states,as demonstrated in a strongly interlayer-coupled monolayer-bilayer PtSe2 heterostructure.The hybridization between the unsaturated states and the interlayer electronic states of PtSe2 significantly reduces the depth of carrier traps at the interface,as corroborated by our scanning tunnelling spectroscopic measurements and density functional theory calculations.The suppressed interfacial trap demonstrates that interlayer saturation may offer an efficient way to relay the charge flow at the interface of TMD heterostructures.Thus,this technique provides an effective way for optimizing the interface contact,the crucial issue exists in two-dimensional electronic community.Xu Wu Jingsi Qiao Liwei Liu Yan Shao Zhongliu Liu Linfei Li Zhili Zhu Cong Wang Zhixin Hu Wei Ji Yeliang Wang Hongjun Gao 2021Nano Research2021,14,5:0
14Study on V_P/ V_S Variation Behavior in the Shanxi Region by the Wadati Single Station and Multi-earthquake Method显示文摘Based on arrival time data of seismic phases of ML≥2. 0 earthquakes measured at Shanxi Digital Seismic Network for the period from January 2001 to October 2014,V_P/ V_S in the Shanxi region is calculated using the Wadati single station and multi-earthquake method,and an investigation is conducted into the variation behavior of V_P/ V_S in the Shanxi region before and after the three earthquakes of MS≥4. 5 in 2010. Our study finds that abnormal V_P/ V_S appeared earlier at distant stations before all of the three earthquakes,which is at the time range from 6 months to 1 year before the earthquakes,and later at near stations,at the time range 10 days to 2 months before earthquakes. Therefore,it  s possible to narrow down the scope of the location in earthquake prediction from the distant and near station data. The calculations of Dongshan seismic station indicate that the size of the residual of the origin time has impact on the detail of V_P/ V_S variation,thus,appropriate thresholds should firstly be set for the residuals of origin time at each seismic station in practical application,to ensure scientific and steady V_P/ V_S calculations.Weng Zhaoqiang Liang Xiangjun Wu Haoyu Liu Linfei Li Li 2015Earthquake Research in China2015,29,4:0
15The Association between Vitamin D and Hashimoto Thyroiditis:An Upto-date Systematic Review and Meta-analysis显示文摘The objective of the surrent study was to summarize the up-to-date studies to investigate the relationship between vitamin D and Hashimoto thyroiditis(HT).An online search of English and Chinese databases was performed.The studies concerned the investigation of the relationship between vitamin D and HT including meta-analysis,meanwhile the heterogeneities were revealed by subgroup analysis.Fourty six elated studies containing 15,336 participants(HT:6,138 versus control:9,198)were included.HT patients had lower levels of 25(OH)D_(3)(standardised mean difference,−1.09;95%CI:[−1.42,−0.75];P<0.01),and were more likely to be deficient in 25(OH)D_(3)(OR,2.77;95%CI,[1.88,3.91];P<0.05).Obvious heterogeneities in the results of meta-analysis were down to the difference of detection methods and criteria of vitamin D insufficiency among studies.Vitamin D deficiency was colncluded to have a significant relation with HT.Zhengrong Liu Linfei Feng Yanfang He Sijie Yuan Chao Xu 2022Food Materials Research2022,2,1:0
16Direct evidence of two-dimensional electron gas-like band structures in hafnene显示文摘Two-dimensional(2D)honeycomb-like materials have been widely studied due to their fascinating properties.In particular,2D honeycomb-like transition metal monolayers,which are good 2D ferromagnet candidates,have attracted intense research interest.The honeycomb-like structure of hafnium,hafnene,has been successfully fabricated on the Ir(111)substrate.However,its electronic structure has not yet been directly elucidated.Here,we report the electronic structure of hafnene grown on the Ir(111)substrate using angle-resolved photoemission spectroscopy(ARPES).Our results indicate that the presence of spin-orbit coupling and Hubbard interaction suppresses the earlier predicted Dirac cones at the K points of the Brillouin zone.The observed band structure of hafnene near the Fermi level is very simple:an electron pocket centered at theΓpoint of the Brillouin zone.This electron pocket shows typical parabolic dispersion,and its estimated electron effective mass and electron density are approximately 1.8_(me)and 7×10^(14)cm^(-2),respectively.Our results demonstrate the existence of 2D electron gas in hafnene grown on the Ir(111)substrate and therefore provide key information for potential hafnene-based device applications.Shaozhu Xiao Meng Liu Linfei Li Jiatao Sun Yeliang Wang Shaolong He 2022Nano Research2022,15,4:0
17Advances in probing single biomolecules: From DNA bases to glycans显示文摘Imaging biomolecules in real space is crucial for gaining a comprehensive understanding of the properties and functions of biological systems at the most fundamental level.Among the various imaging techniques available for biomolecules and their assembled nanostructures,scanning probe microscopy(SPM)provides a powerful and nondestructive imaging option.SPM is unique in visualizing intrinsically disordered biomolecules at the nanometer scale(e.g.,glycans).This review highlights recent achievements in studying biomolecules using SPM technique,focusing on DNA bases,amino acids,proteins,and glycans.The atomic-level analysis of biomolecules made possible by SPM allows for a more accurate definition of the local structure–property relationship.High-resolution SPM imaging of single biomolecules offers a new way to study basic processes of life at the molecular level.Baofei Hou Teng Zhang Huixia Yang Xu Han Liwei Liu Linfei Li Cesare Grazioli Xu Wu Nan Jiang Yeliang Wang 2023Interdisciplinary Materials2023,2,4:0
18Aptamer-functionalized nanoplatforms overcoming temozolomide resistance in synergistic chemo/photothermal therapy through alleviating tumor hypoxia显示文摘Tumor hypoxia is intimately associated with gliomas,which represents a significant threat to human health and are resistant to the first-line chemotherapeutic drug temozolomide(TMZ)due to hypoxia.In this work,to overcome TMZ resistance in orthotopic gliomas,aptamer-functionalized liposomes are manufactured to encapsulate TMZ and photothermal agent IR780,and can cross the blood-brain barrier and actively target gliomas.It is possible to employ liposomes for both fluorescence and photoacoustic imaging simultaneously due to their stability and excellent photothermal conversion capabilities.This chemo/photothermal synergistic therapeutic effect of liposomes on gliomas is demonstrated by their abilities to target orthotopic gliomas,alleviate tumor hypoxia and consequently reverse resistance of glioma cells to TMZ,thereby extending the survival time of tumor-bearing mice,making the nanoplatforms and their synergistic chemo/photothermal therapy as a potential clinical treatment for gliomas.Yun Zeng Linfei Zhao Ke Li Jingwen Ma Dan Chen Changhu Liu Wenhua Zhan Yonghua Zhan 2023Nano Research2023,16,7:0
