| 1 | A study of the spatial-temporal distribution and propagation characteristics of internal waves in the Andaman Sea using MODIS显示文摘This paper describes investigations of the internal waves in the Andaman Sea using Moderate Resolution Imaging Spectroradiometer(MODIS)imagery over the period of June 2010 to May 2016.Results of the spatial and temporal distribution,generation sources and propagation characteristics of internal waves are presented.The statistical analysis shows that internal waves can be observed in almost the entire area of the Andaman Sea.Most internal waves are observed in the northern,central and southern regions of the Andaman Sea.A significant number of internal waves between 7°N and 9°N in the East Indian Ocean are also observed.Internal waves can be observed year-round in the Andaman Sea,while most of internal waves are observed between February and April,with a maximum frequency of 15.03%in March.The seasonal distribution of the internal waves shows that the internal waves have mostly been observed in the dry season(February to April),and fewer internal waves are observed in the rainy season(May to October).The double peak distribution for the occurrence frequency of internal waves is found.With respect to the lunar influence,more internal waves are observed after the spring tide,which implies the spring tide may play an important role in internal wave generation in the Andaman Sea.Generation sources of internal waves are explored based on the propagation characteristics of internal waves.The results indicate that six sources are located between the Andaman Islands and the Nicobar Islands,and one is located in the northern Andaman Sea.Four regions with active internal wave phenomenon in the Andaman Sea were presented during the MODIS survey,and the propagation speed of internal waves calculated based on the semidiurnal generation period is smaller than the results acquired from pairs of the images with short time intervals. | Lina Sun Jie Zhang Junmin Meng | 2019 | Acta Oceanologica Sinica2019,38,7: | 10 |
| 2 | Study on the amplitude inversion of internal waves at Wenchang area of the South China Sea显示文摘The field experiment is conducted from April 16,2005 to July 20,2005 at Wenchang area east of Hainan Island(19°35'N,112°E) of China.Internal wave packets are observed frequently with thermistor chains during the experiment.Meanwhile,internal waves are also detected from a synthetic aperture radar(SAR) image on June 19,2005 and several other moderate-resolution imaging spectroradiometer(MODIS) images near a mooring position.The distance between the positive and negative peaks induced by the internal wave can be obtained from satellite images.Combined with remote sensing images and in situ data,a new method to inverse the amplitude of the internal wave is proposed based on a corrected nonlinear Schr?dinger(NLS) equation.Two relationships are given between the peak-to-peak distance and the characteristic wavelength of the internal wave for different nonlinear and dispersion coefficients.Based on the satellite images,the amplitude inversion of the internal waves are carried out with the NLS equation as well as the Kd V equation.The calculated amplitudes of the NLS equation are close to the observation amplitude which promise the NLS equation a reliable method. | ZHANG Xudong WANG Jing SUN Lina MENG Junmin | 2016 | Acta Oceanologica Sinica2016,35,7: | 8 |
| 3 | A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (http://gffzzc750bc0108fa4044sw590pbovnf956w0o.ffgz.tsg.suse.edu.cn/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants. | Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang | 2018 | Molecular Plant2018,11,11: | 7 |
| 4 | Influence of mechanical alloying time on the properties of Fe_3Al intermetallics prepared by spark plasma sintering显示文摘The Fe3Al-based intermetallics were prepared by mechanical alloying and spark plasma sintering (SPS), and the influence of milling time on the properties of materials was investigated. The phase identification was investigated by X-ray, and the surface morphology and fractography were observed by scanning electron microscope (SEM). The mechanical properties such as bending strength, strain, and microhardness were tested. The results show that Fe reacts with Al completely to form Fe3Al during short SPS processing time. The relative densities of the sintered samples were nearly 100/. The mechanical properties of the sintered samples can be improved along with the milling time. The representative values are the bend strength of 1327 MPa and the microhardness of 434. | Chengchang Jia Qing He Jie Meng Lina Guo | 2007 | Journal of University of Science and Technology Beijing2007,14,4: | 6 |
| 5 | Carbothermic reduction of vanadium titanomagnetite with the assistance of sodium carbonate显示文摘The carbothermic reduction of vanadium titanomagnetite concentrate(VTC)with the assistance of Na_(2)CO_(3)was conducted in an argon atmosphere between 1073 and 1473 K.X-ray diffraction and scanning electron microscopy were used to investigate the phase transformations during the reaction.By investigating the reaction between VTC and Na_(2)CO_(3),it was concluded that molten Na_(2)CO_(3)broke the structure of titanomagnetite by combining with the acidic oxides(Fe_(2)O_(3),TiO_(2),Al_(2)O_(3),and SiO_(2))to form a Na-rich melt and release FeO and MgO.Therefore,Na_(2)CO_(3)accelerated the reduction rate.In addition,adding Na_(2)CO_(3)also benefited the agglomeration of iron particles and the slag–metal separation by decreasing the viscosity of the slag.Thus,Na_(2)CO_(3)assisted carbothermic reduction is a promising method for treating VTC at low temperatures. | Luming Chen Yulan Zhen Guohua Zhang Desheng Chen Lina Wang Hongxin Zhao Fancheng Meng Tao Qi | 2022 | International Journal of Minerals,Metallurgy and Materials2022,29,2: | 5 |
| 6 | Acupuncture effects on the hippocampal cholinergic system in a rat model of neuropathic pain显示文摘The present study observed the effects of repeated electroacupuncture of Zusanli (ST36) and Yanglingquan (GB34) on expression of hippocampal acetylcholinesterase, vesicular acetylcholine transporter, and muscarinic M1 receptor mRNA in chronic constrictive injury (neuropathic pain) and/or ovariotomy rats. Results demonstrated increased expression of hippocampal acetylcholinesterase, vesicular acetylcholine transporter, and muscarinic M1 receptor mRNA, as well as decreased pain threshold, in a rat model of chronic neuropathic pain after electroacupuncture. The effects of electroacupuncture increased with prolonged time, but the above-mentioned effects decreased in memory-deficient animals. Results indicated that repeated electroacupuncture has a cumulative analgesic effect, which is closely associated with upregulation of acetylcholinesterase and vesicular acetylcholine transporter activity, as well as M1 receptor mRNA expression and memory. | Junying Wang Junling Liu Shuping Chen Yonghui Gao Fanying Meng Lina Qiao | 2012 | Neural Regeneration Research2012,7,3: | 4 |
| 7 | Geochronology and Geochemical Characteristics of Intrusion in the Jinchangliang Gold Deposit,Inner Mongolia and Their Tectonic Significance显示文摘Discovered and mined in recent years, the Jinchangliang gold deposit has not yet been studied in its genetic type. In this paper, the geological features of ore deposit, S isotopic composition, metallogenic age and elements geochemical of the granite closely related to mineralization were discussed. The results of the geological features of ore deposit and S isotopic composition show that ore-bearing hydrothermal solution was closely related with the intrusion of magmatic. The granite is characteristic of high silica SiO_2=72.38%–72.98%, high aluminum and Al_2O_3=14.22%–14.35%, low calcium CaO=0.16% –0.26%, and low value of FeOT/MgO(6.86–7.73), and rich in alkalis Na_2O+K_2O=9.11%–9.24%, suggesting that it is high-K calc-alkaline, highly fractionated, weak aluminum A-type granite. The REE patterns are inclined to right and show intense fractionation between LREE and HREE, without obvious negative Eu anomaly(δEu=0.80–0.84). The primitive mantle-normalized spidergrams are characterized by depletion of Ba, U, Ta, Nb, Zr, Ti and P, which implies that the granite has the characteristics of the crust-mantle mixing. S isotopes also indicate that the material source of gold deposit is closely related to the granite rocks. The LA-ICP-MS Zircon UPb age of the Damiao rock mass medium-fine grained monzogranite(belonging to the early IndoChina) is(245±1) Ma. It shows that Jinchangliang gold deposit was not formed in Yanshanian, but the early Indo-China. Specifically speaking, the deposit was formed in the collision stage of the North China plate and the Siberian plate. | SUN Zhenjun SUN Guosheng YU Henan TIAN Yi LIU Shanli XIANG Zhu MENG Jian XUE Huaiyu LU Lina | 2015 | Acta Geologica Sinica(English Edition)2015,89,6: | 4 |

| 9 | Some New Trends of Deep Learning Research显示文摘Deep learning has been attracting increasing attention in the recent decade throughout science and engineering due to its wide range of successful applications.In real problems,however,most implementation stages for applying deep learning still require inevitable manual interventions,which naturally conducts difficulty in its availability to general users with less expertise and also deviates from the intelligence of humans.It is thus a challenging while critical issue to enhance the level of automation across all elements of the entire deep learning framework,like input amelioration,model designing and learning,and output adjustment.This paper tries to list several representative issues of this research topic,and briefly describe their recent research progress and some related works proposed along this research line.Some specific challenging problems have also been presented. | MENG Deyu SUN Lina | 2019 | Chinese Journal of Electronics2019,28,6: | 3 |
| 10 | Sunlight responsive photocatalysts:AgBr/ZnO hybridna nomaterial显示文摘A novel high-effective sunlight-induced AgBr/ZnO hybrid nanophotocatalyst has been synthesized and it was characterized by different techniques such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and ultraviolet-visible spectrophotometry (UV-vis). The AgBr/ZnO hybrid nanophotocatalyst has excellent photocatalytic activity for photodegradation of methyl orange (MO) under sunlight irradiation. The MO degradation efficiency for AgBr/ZnO is about 98% after 1 hour under sunlight irradiation. These results suggested that AgBr/ZnO is a promising candidate for the development of highly efficient sunlight photocatalysts. In addition, the photocatalytic mechanism of AgBr/ZnO under sunlight irradiation is illustrated and discussed. | MENG ALan QIU YanYan ZHANG LiNa XU Xiao LI ZhenJiang | 2012 | Science China Chemistry2012,55,10: | 3 |
| 11 | Improved perovskite solar cell efficiency by tuning the colloidal size and free ion concentration in precursor solution using formic acid additive显示文摘Improving the quality of the perovskite active layer is crucial to obtaining high performance perovskite solar cells(PSCs). In this work, by introducing formic acid into the formamidinium lead iodide(FAPbI3)precursor solution, we managed to achieve reduced colloidal size in the solution, leading to more uniform deposition of FAPbI3 film with lower trap state density and higher carrier mobility. The solar cells based on the FAPbI3 absorber layer modified with formic acid show significantly better photovoltaic performance than that on the reference FAPbI3 film without formic acid. The device performance shows a close correlation with the colloidal size. Within the range studied from 6.7 to 1.0 nm, the smaller the colloidal size is, the higher the solar cell efficiency. More specifically, the cell efficiency is improved from17.82% for the control cell without formic acid to 19.81% when 0.764 M formic acid was used. Formic acid has also been added into a CH3NH3PbI3(MAPbI3) precursor solution, which exhibits a similar effect on the resulting MAPb I3 films and solar cells, with efficiency improved from 16.07% to 17.00%. | Lina Meng Qingbo Wei Zhou Yang Dong Yang Jiangshan Feng Xiaodong Ren Yucheng Liu Shengzhong(Frank)Liu | 2020 | Journal of Energy Chemistry2020,29,2: | 2 |
| 12 | Detection of ocean internal waves based on Faster R-CNN in SAR images显示文摘Ocean internal waves appear as irregular bright and dark stripes on synthetic aperture radar(SAR)remote sensing images.Ocean internal waves detection in SAR images consequently constituted a difficult and popular research topic.In this paper,ocean internal waves are detected in SAR images by employing the faster regions with convolutional neural network features(Faster R-CNN)framework;for this purpose,888 internal wave samples are utilized to train the convolutional network and identify internal waves.The experimental results demonstrate a 94.78%recognition rate for internal waves,and the average detection speed is 0.22 s/image.In addition,the detection results of internal wave samples under different conditions are analyzed.This paper lays a foundation for detecting ocean internal waves using convolutional neural networks. | BAO Sude MENG Junmin SUN Lina LIU Yongxin | 2020 | Journal of Oceanology and Limnology2020,38,1: | 2 |

| 14 | A numerical study of the generation mechanism of internal solitary waves in the Luzon Strait显示文摘The South China Sea(SCS) is a hot spot for oceanic internal solitary waves due to many factors, such as the complexity of the terrain environment. The internal solitary waves in the northern SCS mainly originate in the Luzon Strait. The generation mechanism of the internal solitary waves in the Luzon Strait is discussed using a modulation instability. The energy gain of the modulation instability is derived based on the fully nonlinear Schr?dinger equation. The peak value of the gain is calculated under different conditions of stratification,wavelength and the initial amplitude of an internal tidal wave. The characteristics of the modulation instability in the Luzon Strait are investigated. The conditions that make the internal tidal wave evolve into an internal solitary wave in the Luzon strait are also obtained. The results show that the internal tide waves can generate the modulation instability in the Luzon Strait and that the maximum gain occur at the eastern sill of the Luzon Strait,where the internal tide waves start to break up into internal solitary trains. The magnitude and the scope of the peak gain are relevant to the stratification and the initial conditions of the internal tide waves. The numerical simulation results are consistent with the in-situ data. | WANG Jing SUN Meiling ZHANG Xudong SUN Lina MENG Junmin | 2015 | Acta Oceanologica Sinica2015,34,7: | 2 |

| 17 | Association of genetic polymorphisms of GSTM1 and smoking status with lung cancer risk显示文摘Objective Long-term cigarette smoke exposure damages the airway epithelium.However,the correlation among GSTM1 gene polymorphism,smoking status,and lung cancer susceptibility remains unclear.This study aimed to identify the genetic polymorphism of GSTM1 and examine the association of GSTM1 polymorphism and smoking history with lung cancer susceptibility.Methods The genetic polymorphism of GSTM1 was genotyped by polymerase chain reaction(PCR) in 217 lung cancer patients and 198 controls.The demographic data and smoking history of the patients were collected.The age,sex,and residence of the two groups were also obtained.Results Significant differences in GSTM1 polymorphism were observed between the case and control groups(P=0.024).Smoking time and smoking index were significantly different between the case and control groups.With the increase in smoking time and smoking index,the differences became more obvious.There was a synergistic effect between GSTM1 and smoking(S=3.35).The risk of developing lung cancer increased 4.82 fold in smokers carrying deficient-type GSTM1.Compared with patients carrying wild-type GSTM1,the risk of developing lung cancer was higher in those carrying deficient-type GSTM1 with the increase in smoking time and smoking index.In different pathological types,no significant differences were observed in GSTM1 polymorphism.In different pathological types,the proportions of patients increased with the increase in smoking time and smoking index,especially the proportion of patients with squamous cell carcinoma.Compared with wild-type GSTM1,the proportion of patients with deficient-type GSTM1 increased with the increase in smoking time and smoking index(P=0.003 and 0.017).This trend was mainly observed in those with squamous cell carcinoma.Conclusion GSTM1 mutation is associated with lung cancer susceptibility.Smokers carrying deficienttype GSTM1 are more likely to develop lung cancer.Compared with patients carrying wild-type GSTM1,smokers with deficient-type GSTM1 are more likely develop lung cancer when smoking time is more than 30 years and smoking index is more than 400.In patients carrying deficient-type GSTM1,the risk of developing squamous cell carcinoma increases with an increase in smoking time and smoking dose. | Jiaheng Li Lina Zhang Yue Wang Meng Gu Ziyu Wang Weiying Li | 2019 | Oncology and Translational Medicine2019,5,6: | 2 |
| 18 | Variational Assimilation of Satellite Cloud Water/Ice Path and Microphysics Scheme Sensitivity to the Assimilation of a Rainfall Case显示文摘Hydrometeor variables(cloud water and cloud ice mixing ratios) are added into the WRF three-dimensional variational assimilation system as additional control variables to directly analyze hydrometeors by assimilating cloud observations.In addition,the background error covariance matrix of hydrometeors is modeled through a control variable transform,and its characteristics discussed in detail.A suite of experiments using four microphysics schemes(LIN,SBU-YLIN,WDM6 and WSM6) are performed with and without assimilating satellite cloud liquid/ice water path.We find analysis of hydrometeors with cloud assimilation to be significantly improved,and the increment and distribution of hydrometeors are consistent with the characteristics of background error covariance.Diagnostic results suggest that the forecast with cloud assimilation represents a significant improvement,especially the ability to forecast precipitation in the first seven hours.It is also found that the largest improvement occurs in the experiment using the WDM6 scheme,since the assimilated cloud information can sustain for longer in this scheme.The least improvement,meanwhile,appears in the experiment using the SBU-YLIN scheme. | Yaodeng CHEN Ruizhi ZHANG Deming MENG Jinzhong MIN Lina ZHANG | 2016 | Advances in Atmospheric Sciences2016,33,10: | 2 |
| 19 | Assembly-promoted photocatalysis:Three-dimensional assembly of CdS_(x)Se_(1-x)(x=0-1) quantum dots into nanospheres with enhanced photocatalytic performance显示文摘In this paper,through an emulsion-based bottom-up self-assembly method,monodisperse CdS_(x)Se_(1-x)(x=0-1)quantum dots(QDs)with tailoring compositions have been three-dimensionally assembled into spherical architectures in sub-micrometer sizes.UVeVis absorption measurements revealed the enhanced light harvesting abilities of the assembled CdS_(x)Se_(1-x) spheres relative to their constituting QDs.HRTEM characterizations over the CdS_(x)Se_(1-x) assemblies suggested the existence of localized oriented adjoining of the CdS_(x)Se_(1-x) QDs and the resulting nano-twin structures that are favorable for photogenerated electron-hole separation.The quenching of photoluminescence and the improvement in IPCE after the assembly of CdS_(x)Se_(1-x) QDs provided a clue to the likely suppressed electron-hole recombination brought about by the unique architectures and interfaces derived from self-assembly.The above findings were coincided with the remarkably improved H2 evolution activities observed for the wellassembled CdS_(x)Se_(1-x) nanospheres in photocatalytic water splitting,underpinning the importance of the alternative strategy to design advanced semiconductor photocatalysts based on architectural engineering. | Lina Wang Qiumei Di Mingming Sun Jia Liu Chuanbao Cao Jiajia Liu Meng Xu Jiatao Zhang | 2017 | Journal of Materiomics2017,3,1: | 2 |
| 20 | Single-cell analysis of cellular heterogeneity and interactions in the ischemia-reperfusion injured mouse intestine显示文摘Nine major cell populations among 46,716 cells were identified in mouse intestinal ischemia‒reperfusion(II/R)injury by single-cell RNA sequencing.For enterocyte cells,11 subclusters were found,in which enterocyte cluster 1(EC1),enterocyte cluster 3(EC3),and enterocyte cluster 8(EC8)were newly discovered cells in ischemia 45 min/reperfusion 720 min(I 45 min/R 720 min)group.EC1 and EC3 played roles in digestion and absorption,and EC8 played a role in cell junctions.For TA cells,after ischemia 45 min/reperfusion 90 min(I 45 min/R 90 min),many TA cells at the stage of proliferation were identified.For Paneth cells,Paneth cluster 3 was observed in the resting state of normal jejunum.After I 45 min/R 90 min,three new subsets were found,in which Paneth cluster 1 had good antigen presentation activity.The main functions of goblet cells were to synthesize and secrete mucus,and a novel subcluster(goblet cluster 5)with highly proliferative ability was discovered in I 45 min/R 90 min group.As a major part of immune system,the changes in T cells with important roles were clarified.Notably,enterocyte cells secreted Guca2b to interact with Gucy2c receptor on the membranes of stem cells,TA cells,Paneth cells,and goblet cells to elicit intercellular communication.One marker known as glutathione S-transferase mu 3(GSTM3)affected intestinal mucosal barrier function by adjusting mitogen-activated protein kinases(MAPK)signaling during II/R injury.The data on the heterogeneity of intestinal cells,cellular communication and the mechanism of GSTM3 provide a cellular basis for treating II/R injury. | Lianhong Yin Meng Gao Lina Xu Yan Qi Lan Han Jinyong Peng | 2023 | Journal of Pharmaceutical Analysis2023,13,7: | 1 |
