| 1 | Removal of cyanide adsorbed on pyrite by H_2O_2 oxidation under alkaline conditions显示文摘Large amounts of cyanide tailings are produced during the cyanidation process in gold extraction,which are hazardous solid wastes due to the toxic cyanide.Pyrite is one of the main minerals in cyanide tailings.The removal of cyanide adsorbed on pyrite by H_2O_2 oxidation under alkaline conditions was investigated in this study.It was found that the removal efficiency was positively correlated with pH from 5 to 12,but remained almost constant when pH was higher than 12.The highest cyanide removal efficiency of 91.10% was achieved by adding no less than 0.6 wt.% of H_2O_2.Cyanide removal was positively correlated with the CN^-adsorption amount between 1.06 and 8.5 mg/g,and temperature between 25 and 85°C.The removal of cyanide adsorbed on pyrite by H_2O_2 oxidation under alkaline conditions was due to the oxidation of pyrite.Hexacyanoferrate,thiocyanate and sulfate were generated with mole ratios of about 2.03:1.12:3.17 during the cyanide removal.?2018 The Research Center for Eco-Environmental Sciences,Chinese Academy of Sciences. | Yubo Tu Peiwei Han Lianqi Wei Xiaomeng Zhang Bo Yu Peng Qian Shufeng Ye | 2019 | Journal of Environmental Sciences2019，31，4： | 8 |
| 2 | Building a sequence map of the pig pan-genome from multiple de novo assemblies and Hi-C data显示文摘Pigs were domesticated independently in the Near East and China,indicating that a single reference genome from one individual is unable to represent the full spectrum of divergent sequences in pigs worldwide.Therefore,12 de novo pig assemblies from Eurasia were compared in this study to identify the missing sequences from the reference genome.As a result,72.5 Mb of nonredundant sequences(~3% of the genome)were found to be absent from the reference genome(Sscrofa11.1)and were defined as pan-sequences.Of the pan-sequences,9.0 Mb were dominant in Chinese pigs,in contrast with their low frequency in European pigs.One sequence dominant in Chinese pigs contained the complete genic region of the tazarotene-induced gene 3(TIG3)gene which is involved in fatty acid metabolism.Using flanking sequences and Hi-C based methods,27.7% of the sequences could be anchored to the reference genome.The supplementation of these sequences could contribute to the accurate interpretation of the 3D chromatin structure.A web-based pan-genome database was further provided to serve as a primary resource for exploration of genetic diversity and promote pig breeding and biomedical research. | Xiaomeng Tian Ran Li Weiwei Fu Yan Li Xihong Wang Ming Li Duo Du Qianzi Tang Yudong Cai Yiming Long Yue Zhao Mingzhou Li Yu Jiang | 2020 | Science China(Life Sciences)2020，63，5： | 7 |
| 3 | Construction of Co_(2)NiO_(4)@MnCo_(2)O_(4.5)nanoparticles with multiple hetero-interfaces for enhanced electromagnetic wave absorption显示文摘Nanocomposites with heterogeneous structures and magneto-electric synergistic losses have broad prospects for improving electromagnetic wave(EMW)absorption performance.In this study,we synthesized Co_(2)NiO_(4)@MnCo_(2)O_(4.5)nanoparticles with abundant hetero-interfaces and multiple magnetoelectric loss mechanisms by a facile hydrothermal method.The excess 0.5 oxygen atoms in MnCo_(2)O_(4.5) produce more vacancies and contribute to the enhancement of electrical conductivity.Sequential nanoneedle clusters facilitate multiple reflections and absorption of EMW in the materials,which are accompanied by an abundance of heterogeneous interfaces to improve the dielectric loss.The Co_(2)NiO_(4)@MnCo_(2)O_(4.5)composites showed a minimum reflection loss(RLmin)of30.01 dB and a superior effective absorption bandwidth(EAB)of 6.12 GHz(11.88 GHze18 GHz)at a thickness of 2.00 mm.Computer Simulation Technology(CST)revealed that the obtained particles show very low radar crosssection(RCS)values and almost full coverage angles.The maximum reduction of RCS at vertical incidence reaches 19.98 dB m2.The Co_(2)NiO_(4)@MnCo_(2)O_(4.5)nanoparticles exhibit outstanding radar attenuation properties,which can effectively inhibit the reflection and scattering of EMW.Therefore,the prepared Co_(2)NiO_(4)@MnCo_(2)O_(4.5)absorbers have great application potential in the field of EMW absorption. | Yi Zhang Shujuan Tan Zhuoting Zhou Xiaomeng Guan Yu Liao Chen Li Guangbin Ji | 2023 | Particuology2023，，10： | 5 |
| 4 | Reservoir characteristics and well-logging evaluation of the Lower Cambrian shales in southeast Chongqing, China显示文摘To accurately identify the reservoir characteristics and main controlling factors of the Cambrian Niutitang black shale in the southeast Chongqing,a series of systematic measurements were conducted on core samples from Well Yuke-1 and Well Youke-1.The measurements include clay mineral analysis,XRD analysis,petrophysical properties,specific surface area,pore diameter and TOC,as well as R_(o) and maceral compositions.The Niutitang shale reservoir contains detrital minerals and clay minerals averagely of 51.34%and 32.74%,respectively.The average effective porosity and permeability are 1.2%and 8.0×10^(-3)mD,respectively,typically of ultra-low porosity and permeability.Mesopores are dominant,accounting for approximately 73%of the total pore volume.The average BET specific surface area is 7.75m^(2)/g and the average pore diameter is 5.3nm.The average TOC is 2.29%and the average R_(o) is 3.12%,indicating that the organic matter is in over-maturity stage.Statistical analyses of the measurements show that the micropore volume is positively correlated with TOC but negatively correlated with the total content of clay minerals;the mesopore volume is positively correlated with TOC,the total content of clay minerals and the content of carbonate minerals;the macropore volume is positively correlated with TOC and the content of carbonate minerals,weakly positively correlated with the content of detrital minerals but negatively correlated with the total content of clay minerals.The porosity and TOC of the Niutitang shale are computed using the conventional well-logging method for the Yuke-1 and Youke-1 wells,and the porosities are quite consistent with the core analysis resultsr,but in the shallow reservoir that contains no oil and gas,the TOC exhibits no correlation with the core analysis results. | Xiaomeng Cao Bingsong Yu Xintong Li Mengdi Sun Ling Zhang | 2016 | Petroleum Research2016，1，2： | 3 |
| 5 | Demonstration of epitaxial growth of strain-relaxed GaN films on graphene/SiC substrates for long wavelength light-emitting diodes显示文摘Strain modulation is crucial for heteroepitaxy such as GaN on foreign substrates.Here,the epitaxy of strain-relaxed GaN films on graphene/SiC substrates by metal-organic chemical vapor deposition is demonstrated.Graphene was directly prepared on SiC substrates by thermal decomposition.Its pre-treatment with nitrogen-plasma can introduce C–N dangling bonds,which provides nucleation sites for subsequent epitaxial growth.The scanning transmission electron microscopy measurements confirm that part of graphene surface was etched by nitrogen-plasma.We study the growth behavior on different areas of graphene surface after pre-treatment,and propose a growth model to explain the epitaxial growth mechanism of GaN films on graphene.Significantly,graphene is found to be effective to reduce the biaxial stress in GaN films and the strain relaxation improves indium-atom incorporation in InGaN/GaN multiple quantum wells(MQWs)active region,which results in the obvious red-shift of light-emitting wavelength of InGaN/GaN MQWs.This work opens up a new way for the fabrication of GaN-based long wavelength light-emitting diodes. | Ye Yu Tao Wang Xiufang Chen Lidong Zhang Yang Wang Yunfei Niu Jiaqi Yu Haotian Ma Xiaomeng Li Fang Liu Gaoqiang Deng Zhifeng Shi Baolin Zhang Xinqiang Wang Yuantao Zhang | 2021 | Light(Science & Applications)2021，10，7： | 2 |

| 7 | Postnatal state transition of cardiomyocyte as a primary step in heart maturation显示文摘Postnatal heart maturation Is the basis of normal cardiac function and provides critical insights into heart repair and regenerative medicine.While static snapshots of the maturing heart have provided much Insight into its molecular signatures,few key events during postnatal cardiomyocyte maturation have been uncovered.Here,we report that cardiomyocytes(CMs)experience epige-netic and transcriptional decline of cardiac gene expression immediately after birth,leading to a transi-tion state of CMs at postnatal day 7(P7)that was essential for CM subtype specification during heart maturation.Large-scale single-cell analysis and genetic lineage tracing confirm the presence of transition state CMs at P7 bridging immature state and mature states.Silencing of key transcription factor JUN In P1-hearts significantly repressed CM transition,resulting in per-turbed CM subtype proportions and reduced cardiac function in mature hearts.In addition,transplantation of P7-CMs into infarcted hearts exhibited cardiac repair potential superior to P1-CMs.Collectively,our data uncover CM state transition as a key event in postnatal heart maturation,which not only provides insights into molecular foundations of heart maturation,but also opens an avenue for manipulation of cardiomyocyte fate in disease and regenerative medicine. | Zheng Li Fang Yao Peng Yu Dandan Li Mingzhi Zhang Lin Mao Xiaomeng Shen Zongna Ren Li Wang Bingying Zhou | 2022 | Protein & Cell2022，13，11： | 2 |
| 8 | Underwater target feature recognition based on distribution of highlights显示文摘An algorithm for underwater target feature recognition is proposed using its highlights distribution.For an underwater target with large size and slender body,it is assumed that the heading course and the length of the target are both determined by the distribution of its highlights.By supposing that these highlights obey Gaussian mixture distribution,the feature recognition problem can be transformed into a clustering problem.Therefore,using the collinearly constrained expectation maximization algorithm,the clustering centers of these highlights can be calculated and then the estimation of the heading and length of the target can be obtained with high accuracy.The effectiveness of the proposed method is demonstrated using simulations. | LIU Yu ZHU Xiaomeng YAN Shefeng MA Xiaochuan WU Yongqing | 2016 | Chinese Journal of Acoustics2016，35，4： | 2 |

| 10 | Automatic modulation classification based on Alex Net with data augmentation显示文摘Deep learning(DL) requires massive volume of data to train the network. Insufficient training data will cause serious overfitting problem and degrade the classification accuracy. In order to solve this problem, a method for automatic modulation classification(AMC) using AlexNet with data augmentation was proposed. Three data augmentation methods is considered, i.e., random erasing, CutMix, and rotation. Firstly, modulated signals are converted into constellation representations. And all constellation representations are divided into training dataset and test dataset. Then, training dataset are augmented by three methods. Secondly, the optimal value of execution probability for random erasing and CutMix are determined. Simulation results show that both of them perform optimally when execution probability is 0.5. Thirdly, the performance of three data augmentation methods are evaluated. Simulation results demonstrate that all augmentation methods can improve the classification accuracy. Rotation improves the classification accuracy by 13.04% when signal noise ratio(SNR) is 2 dB. Among three methods, rotation outperforms random erasing and CutMix when SNR is greater than-6 dB. Finally, compared with other classification algorithms, random erasing, CutMix, and rotation used in this paper achieved the performance significantly improved. It is worth mentioning that the classification accuracy can reach 90.5% with SNR at 10 dB. | Zhang Chengchang Xu Yu Yang Jianpeng Li Xiaomeng | 2022 | The Journal of China Universities of Posts and Telecommunications2022，29，5： | 1 |

| 13 | Construction of a high-density mutant population of Chinese cabbage facilitates the genetic dissection of agronomic traits显示文摘Chinese cabbage(Brassica rapa ssp.pekinensis)is an economically important vegetable crop throughout the world,especially in Asia.High-quality genome sequences are available for Chinese cabbage,but gene functional studies remain challenging.To promote functional genomic studies of Chinese cabbage,we generated an ethyl methane sulfonate(EMS)mutant population of~8000 M_(2) plants using the double haploid inbred line A03 as the parent.The genome of A03 was sequenced and used as a reference for high-throughput functional characterization of gene mutations at the whole-genome level.A total of 300 M_(2) to M_(5) EMS mutants were phenotypically screened and then sequenced,revealing 750629 SNPs and 46272 InDel mutations that cover 98.27%of all predicted genes in the A03 genome.A forward-genetics approach was successfully used to identify two genes with chloroplast-related functions that are responsible for the yellow leaf mutant trait.A reverse-genetics approach was also used to identify associations between mutations in five genes of the glucosinolate biosynthetic pathway and variations in glucosinolate content of the mutant plants.In addition,we built the Chinese cabbage EMS mutation database(CCEMD,www.bioinformaticslab.cn/EMSmutation/home)to increase the usability of this mutant population resource.In summary,we performed large-scale screening of a heading Chinese cabbage EMS mutant collection at the phenotypic and genotypic levels,which will facilitate gene mining of Chinese cabbage and might also be useful for the study of other Brassica crops. | Xiaoxue Sun Xing Li Yin Lu Shan Wang Xiaomeng Zhang Kang Zhang Xiangjie Su Mengyang Liu Daling Feng Shuangxia Luo Aixia Gu Yu Fu Xueping Chen Shuxin Xuan Yanhua Wang Donghui Xu Shumin Chen Wei Ma Shuxing Shen Feng Cheng Jianjun Zhao | 2022 | Molecular Plant2022，15，5： | 1 |
| 14 | Highly Stretchable and Permeable Conductors Based on Shrinkable Electrospun Fiber Mats显示文摘Wearable on-skin electrodes or conductors should be vapor permeable,strain-insensitive,isotropically stretchable and stable under cyclic stretching.Various strategies have been proposed to prepare the required conductors up to now;however,it is a challenge to fabricate them with above properties in a simple manner.In this paper,a highly permeable and stretchable conductor based on electrospun fluorine rubber fiber mat is reported.The fibers are pre-stretched in electric field during electrospinning,and they shrink isotropically by~35-40%in area after being detached from the substrate.The obtained fiber mat conductor demonstrates high stretchability up to~170%,and the resistance changes only 0.8 under 60%strain,which is superior to many other strain-insensitive conductors.The conductor possesses high stability,no cracks or structure damage are observed after washing and cyclic stretching.Moreover,the conductor is vapor permeable with a water vapor transmission rate of~850 g m−2 day−1,which is comparable to the normal water evaporation in ambient conditions,indicating that it would not disturb the sweat evaporation when being used on skin.The conductor is successfully used as stretchable yarns and electromyography(EMG)electrodes,showing high reliability in E-textiles and on-skin applications. | Qingsong Li Chen Ding Wei Yuan Ruijie Xie Xiaomeng Zhou Yang Zhao Mei Yu Zijian Yang Jing Sun Qiong Tian Fei Han Hanfei Li Xinping Deng Guanglin Li Zhiyuan Liu | 2021 | Advanced Fiber Materials2021，3，5： | 1 |

| 16 | Schaftoside inhibits 3CL^(pro)and PL^(pro)of SARS-CoV-2 virus and regulates immune response and inflammation of host cells for the treatment of COVID-19显示文摘It is an urgent demand worldwide to control the coronavirus disease 2019(COVID-19)pandemic caused by the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)virus.The 3-chymotrypsin-like protease(3CL^(pro))and papain-like protease(PL^(pro))are key targets to discover SARS-CoV-2 inhibitors.After screening 12 Chinese herbal medicines and 125 compounds from licorice,we found that a popular natural product schaftoside inhibited 3CL^(pro)and PL^(pro)with IC_(50)values of 1.73±0.22 and 3.91±0.19μmol/L,respectively,and inhibited SARS CoV-2 virus in Vero E6 cells with EC_(50)of 11.83±3. 23μmol/L. Hydrogen-deuterium exchange mass spectrometry analysis, quantum mechanics/molecular mechanics calculations, together with site-directed mutagenesis indicated the antiviral activities of schaftoside were related with non-covalent interactions with H41, G143 and R188 of3CLpro, and K157, E167 and A246 of PLpro. Moreover, proteomics analysis and cytokine assay revealed that schaftoside also regulated immune response and inflammation of the host cells. The antiinflammatory activities of schaftoside were confirmed on lipopolysaccharide-induced acute lung injury mice. Schaftoside showed good safety and pharmacokinetic property, and could be a promising drug candidate for the prevention and treatment of COVID-19. | Yang Yi Meng Zhang Heng Xue Rong Yu Yang-Oujie Bao Yi Kuang Yue Chai Wen Ma Jing Wang Xiaomeng Shi Wenzhe Li Wei Hong Junhua Li Elishiba Muturi Hongping Wei Joachim Wlodarz Szczepan Roszak Xue Qiao Hang Yang Min Ye | 2022 | Acta Pharmaceutica Sinica B2022，12，11： | 0 |
| 17 | Performance Evaluation of Combined Detection of Serum CEA,CYFRA21-1,CA125,and NSE in Patients with Lung Cancer by Fluorescence Flow Cytometry显示文摘Objective:To investigate the effect of combined detection of serum carcinoembryonic antigen(CEA),cytokeratin 19 fragment(CYFRA21-1),cancer antigen 125(CA125),and neuron-specific enolase(NSE)in patients with lung cancer by fluorescence flow cytometry.Methods:From August 2019 to July 2022,200 patients with lung cancer diagnosed by pathology in our hospital were retrospectively analyzed.2 mL venous blood was collected in a fasting state and centrifuged to separate the serum(containing human chorionic gonadotropin antibody[anti-hCG antibody],hepatitis B surface antibody[anti-HBs antibody],and CEA).Results:The sensitivities of CEA and CYFRA21-1 detected via enzyme-linked immunosorbent assay(ELISA)were 100%,and the detection limits were 0.5 ng/mL and 0.1 ng/mL,respectively;the sensitivities of CA125 and NSE detected via flow cytometry were 100%,and the detection limits were 10 U/mL and 2 ng/mL,respectively.Compared with ELISA,the sensitivities of CA125 and NSE detected via flow cytometry were higher.When the concentration of CEA was 10-40 ng/mL,the sensitivities of the three markers CYFRA21-1,CA125,and NSE showed no significant changes(P>0.05);when the concentration of CEA was 40-80 ng/mL,the sensitivity of CEA significantly decreased(P<0.01),but the sensitivities of the three markers CYFRA21-1,CA125,and NSE showed no significant changes(P>0.05);when the concentration of CEA was 80-200 ng/mL,the sensitivities of all four markers showed no significant changes(P>0.05).Conclusion:Compared with the double-antibody sandwich ELISA,fluorescence flow cytometry has certain advantages,including high sensitivity,good precision,short detection time,low sample usage,and low medical cost;thus,it is worthy of clinical promotion. | Xiaoxue Huang Xiaomeng Zheng Yiyang Li Lin Duan Yang Yu | 2023 | Proceedings of Anticancer Research2023，7，3： | 0 |

| 19 | Population Genetic Analysis of Sillago nigrofasciata (Perciformes:Sillaginidae) Along the Coast of China by Sequencing Mitochondrial DNA Control Region显示文摘Sillago nigrofasciata, a small to moderate size nearshore species, is newly found along the eastern and southern coasts of China. The present study is carried out in order to analyze the population genetics of the S. nigrofasciata. The control region sequence of mitochondrial DNA revealing 73 haplotypes were obtained from 162 individuals collected at 8 locations along the coast of China. The whole S. nigrofasciata population along the coast of China showed a low nucleotide diversity(0.012) and a high population diversity(haplotype diversity)(0.943), and all the 8 local populations showed low nucleotide diversities(0.014 – 0.001), suggesting the protective measures are effective. The haplotypes of the 8 local populations were widely distributed in haplotype network diagram and neighbor-joining phylogenetic tree, while no branch associating with sampling locations was detected. Recent gene flow analysis showed asymmetric gene exchanges among local populations. The pairwise FST values and unweighted pair-group method with arithmetic mean(UPGMA) tree revealed a certain amount of genetic difference among local populations. Moreover, analysis of molecular variance(AMOVA) reflected genetic differences between hypothetical subdivision groups. Neutral test and mismatch distribution of pairwise nucleotide suggested S. nigrofasciata may have experienced recent population expansion events. The historical geographic events associating with ice age may be the main explanation to the heterogeneity among local populations with short geographic distances, and the homogeneity among local populations with long geographic distances. | ZHANG Xiaomeng GAO Tianxiang YE Yingying SONG Na YU Zhengsen LIU Yong | 2020 | Journal of Ocean University of China2020，19，3： | 0 |
| 20 | Deep Learning for Seasonal Precipitation Prediction over China显示文摘Despite significant progress having been made in recent years,the forecast skill for seasonal precipitation over China remains limited.In this study,a deep-learning-based statistical prediction model for seasonal precipitation over China was developed.The model was trained to learn the distribution of the seasonal precipitation using simultaneous general circulation data.First,it was pre-trained with the hindcasts of several general circulation models(GCMs),and evaluation of the test set suggested that the pre-trained model could basically reproduce the GCM-predicted precipitation,with the anomaly pattern correlation coefficients(PCCs)greater than 0.80.Then,transfer learning was applied by using ECMWF Reanalysis v5(ERA5)data and gridded precipitation observational data over China,to further correct the systemic errors in the model.As a result,using general circulation fields from reanalysis as the input,this hybrid model performed reasonably well in simulating the seasonal precipitation over China,with the PCC reaching 0.71.In addition,the results using the circulation fields predicted by GCMs as the input were also assessed.In general,the proposed model improves the PCC over China by 0.10-0.13,as compared to the raw GCM outputs,for lead times of 1-4 months.This deep learning model has been used at the National Climate Center of China Meteorological Administration for the past two years to provide guidance for summer precipitation prediction over China and has performed extremely well. | Weixin JIN Yong LUO Tongwen WU Xiaomeng HUANG Wei XUE Chaoqing YU | 2022 | Journal of Meteorological Research2022，36，2： | 0 |
