2Detection of serum IgM and IgG for COVID-19 diagnosis显示文摘Dear Editor,Infection with the novel coronavirus(SARS-CoV-2,which is the virus responsible for the coronavirus disease 2019(COVID-19))was first reported in Wuhan,China on December 31,2019.The outbreak of COVID-19 remains ongoing and was linked to more than 80,000 infected patients and more than 3,000 deaths in China as of March 7,2020(Holshue et al.,2020).Ling Zhong Junlan Chuan Bo Gong Ping Shuai Yu Zhou Yi Zhang Zhilin Jiang Dingding Zhang Xiaoqi Liu Shi Ma Yi Huang He Lin Qingwei Wang Lulin Huang Dan Jiang Fang Hao Juan Tang Chunqi Zheng Hua Yu Zhibin Wang Qi Jiang Tao Zeng Mei Luo Fanwei Zeng Fanxin Zeng Jianghai Liu Junxi Tian Yu Xu Tengxiang Long Kaiju Xu Xingxiang Yang Yuping Liu Yi Shi Li Jiang Zhenglin Yang 2020Science China(Life Sciences)2020,63,5:8
3FTIR Study of White and Green Broad Beans Based on Curve-fitting显示文摘Fourier transform infrared(FTIR)spectroscopy was used to study two kinds of broad beans with white and green cotyledons respectively.The results show that the infrared spectra of the two kinds of broad beans are similar and mainly made up of the absorption bands of protein,and polysaccharides.The second derivative infrared spectra amplified the differences and revealed that there were some obvious differences in the range of 1 800-700 cm-1and 1 200-700 cm-1.Hierarchical cluster analysis(HCA)were used for the discrimination of the two kinds broad beans based on the second derivative spectral data in the region of 1 611-1 100 cm-1,and yielded 88.9%accuracy.The spectra in the range from 1 700 to 1 600 cm-1were used to perform Fourier self-deconvolution and curve fitting,which obtained nine peaks.The ratios of relative areas of the bands atα-helix,β-sheet,β-turn and the unordered structure of protein in white beans were 67.71%,35.6%,35.6%and 21.09%respectively,while the ratios in green beans were 8.02%,31.59%,37.12%and 23.27%respectively.The results indicate that the secondary structure of protein was different in the two kinds of broad beans.Xiaohua WANG Gang LIU Quanhong OU Xingxiang ZHAO Jianming HAO Xiangping ZHOU 2013Asian Agricultural Research2013,5,12:2
4Thermodynamic Study on Process in Copper Converters(The slag-making stage)显示文摘The so-called Goto’s model was modified by introducing a parameter of the oxygen efficiency from industrial trials, as well as the selected and newly re-assessed thermodynamic data. The application of the model to copper converters in Guixi Smelter has been carried out by the combination of thermodynamic calculations with the mass and heat balance using the plant data obtained in industrial trials for many heats. For the slag-making stage, good agreements have been reached betWeen the calculated and measured temperature, blowing time as well as the contents for main elements in the matte and the slag. Relativel}’’ large deviations for contents of Zn and Pb in the slag may be caused by the complex chemical composition of the real molten slag, which ma}; result in a large difference of γzn. and γPb,adopted with their real values. It is noted that the model can simulate the slag-making stage of copper converting process in industrial Pierce-Smith converters well.Chunlin Chen Tuping Zhou Jiayun Zhang Shoukun Wei Xingxiang Lu Meng Bai Jinhong Jiang(Metallurgy School, University of Science and Technology Beijing, Beijing 100083, China)(Guixi Smelter, Jiangxi Province 333424, China) 1999International Journal of Minerals,Metallurgy and Materials1999,13,3:2
5Rice(Oryza sativa L.)seedlings enriched with zinc or manganese:Their impacts on cadmium accumulation and expression of related genes显示文摘Cadmium(Cd)contamination in paddy soils means that the rice produced there may be unsafe for human consumption.A hydroponic study was conducted to enrich rice seedlings with zinc(Zn)or manganese(Mn),and the uptake and transport characteristics of Cd in these Zn-and Mn-rich seedlings were subsequently investigated using a greenhouse pot trial.The results showed that hydroponic cultivation in 10-50μmol L^(-1) Zn(ZnSO_(4)·7 H_(2)O)or50-250μmol L^(-1) Mn(MnSO_(4)·H_(2)O)for 30 d had no significant impact on rice growth,while the accumulation of Zn and Mn was 7.31-18.5 and 25.4-47.7 times higher,respectively,than in the control(no Zn or Mn addition).The accumulation of Cd in the Zn-and Mn-rich rice plants was 26.3%-38.6% and 34.4%-44.5% lower than that in the control,respectively,and the translocation factors of Cd from roots to shoots also decreased by 23.3%-41.3% and 25.3%-37.0%,respectively,after transplanting to Cd-contaminated soils.Furthermore,the relative expression levels of OsIRT1(Oryza sativa iron-regulated transporter 1)were downregulated by 40.1%-59.3% and 16.0%-25.9%,respectively,in the Zn-and Mn-rich seedling roots.This downregulation may indicate a possible mechanism contributing to the reductions in Cd absorption.Field experiments confirmed that the Zn-and Mn-rich seedlings produced brown rice(unpolished rice grains)with significantly decreased concentrations of Cd(34.2%-44.4%).This study provides an innovative method for reducing the food safety risks from rice grown on slightly to moderately Cd-contaminated paddy soils.Gaoxiang HUANG Changfeng DING Yibing MA Yurong WANG Zhigao ZHOU Shun'an ZHENG Xingxiang WANG 2021Pedosphere2021,31,6:2

7Design and fabrication of superconducting transition edge sensor bolometers with background limited noise performance显示文摘We successfully designed and fabricated TES bolometers utilizing Al/Ti bilayer TESs as sensitive thermometers.To reduce the intrinsic noise level and tune the saturation power of a bolometer,the TES thermometer is placed on a suspended SiN platform which is thermally coupled to the heat bath by four long SiN beams with different geometries.The measurement results show that the detectors have background limited noise performance,with a low noise equivalent power(NEP)on the order of10-17W/Hz1/2and have a saturation power of several tens pW at a bath temperature of 320 mK.These detectors are suitable for applications in ground-based astrophysics experiments by integrating absorbers for specific wavelengths.Qingya Zhang Jianshe Liu Wenhui Dong Tianshun Wang Genfang He Tiefu Li Xingxiang Zhou Wei Chen 2014Chinese Science Bulletin2014,59,19:1
8Thermodynamic Study on Process in Copper Converters (The Copper-making Stage)显示文摘Theoretical calculations were based on thermodynamic equilibrium in the multi-component and multi-phase system with heat and mass balance as well as the oxygen efficiency to take account for the effects of process kinetics. The variations of temperature, mass fractions of dissolved oxygen and sulfur in blister copper, partial pressures for O2, S2, SO2 in gas phase for the copper-making stage were calculated. The model predicted temperature, time of blowing as well as mass of the blister copper at end points for 6 heats showed a fairly good agreements with corresponding plant data. The calculated content of 0.065% and content of 0.87% in blister copper were both at reasonable levels. Compared with the so called Goto model, the present model has very much improved process description of copper-making stage as well as the prediction of end points for a copper converter by introducing the oxygen efficiency.Chunlin Chen, Jiayun Zhang, Tuping Zhou, Shoukun Wei, Xingxiang Lu2), Meng Bai, Jinhong Jiang ( Metallurgy School, University of Science and Technology Beijing, Beijing 100083, China Guixi Smelter, Jiangxi, 335424) 2000International Journal of Minerals,Metallurgy and Materials2000,14,3:1
9Review on application of phase change materials in asphalt pavement显示文摘Phase change materials(PCMs)can regulate the temperature in asphalt pavement and minimize temperature-related problems,such as rutting and thermal cracking,because of their ability to store and release latent heat.Suitable PCMs can also enable additional road surface functions,such as snow melting ability,freeze-thaw cycle resistance,and heat island reduction.These functions are helpful in achieving intelligent,green,and sustainable transportation systems.Although the research on PCMs for asphalt pavement has been carried out for more than 10 years,a systematic material system and mature application technology have not yet been formed.The main reasons for restricting the development of this technology include the lack of suitability between the PCMs and asphalt pavement,the quantitative characterization of phase change temperature regulation property,and the evaluation of the effect of phase change energy storage on improving pavement performance.Although the published review has made a comprehensive summary of the existing research,it has yet to identify the key restricting the development of this technology and carry out a review and discussion based on it.To grasp the development status of the application of PCMs in asphalt pavement,sort out the development needs and break through the technical barriers,this study systematically summarizes the preparation and performance of PCMs for asphalt pavement,compares the performance and evaluation methods of asphalt mixtures with different PCMs,and summarizes the numerical simulation methods of phase change asphalt mixtures.Finally,this study presents potential approaches to address critical technical issues and discusses possible future research.Xiaoqing Wang Biao Ma Siqi Li Wei Si Kun Wei Hongfei Zhang Xueyan Zhou Yunfeng Fang Xingxiang Kang Wenshuo Shi 2023Journal of Traffic and Transportation Engineering(English Edition)2023,10,2:0
10MSC based gene delivery methods and strategies improve the therapeutic efficacy of neurological diseases显示文摘Mesenchymal stem cells(MSCs)are promising seed cells for neural regeneration therapy owing to their plasticity and accessibility.They possess several inherent characteristics advantageous for the transplantation-based treatment of neurological disorders,including neural differentiation,immunosuppression,neurotrophy,and safety.However,the therapeutic efficacy of MSCs alone remains unsatisfactory in most cases.To improve some of their abilities,many studies have employed genetic engineering to transfer key genes into MSCs.Both viral and nonviral methods can be used to overexpress therapeutic proteins that complement the inherent properties.However,to date,different modes of gene transfer have specific drawbacks and advantages.In addition,MSCs can be functionalized through targeted gene modification to facilitate neural repair by promoting neural differentiation,enhancing neurotrophic and neuroprotective functions,and increasing survival and homing abilities.The methods of gene transfer and selection of delivered genes still need to be optimized for improved therapeutic and targeting efficacies while minimizing the loss of MSC function.In this review,we focus on gene transport technologies for engineering MSCs and the application of strategies for selecting optimal delivery genes.Further,we describe the prospects and challenges of their application in animal models of different neurological lesions to broaden treatment alternatives for neurological diseases.Heng Zhou Yan He Wei Xiong Shuili Jing Xingxiang Duan Zhiyun Huang Gurek SNahal Youjian Peng Mingchang Li Yaoqi Zhu Qingsong Ye 2023Bioactive Materials2023,,5:0
11Discrimination of Five Citrus Diseased Leaves by FTIR Spectroscopy显示文摘In this paper,citrus brown spot,huanglongbing,canker,fuliginous,Cercospora sp. and healthy leaves were studied using Fourier transform infrared spectroscopy( FTIR) combined with statistical analysis. The results showed that the spectra of the samples were similar,whereas there were obvious differences in the second derivatives of infrared spectra in the range of 1 500- 700 cm- 1. The correlative analysis were evaluated,results showed that the correlation coefficients were larger than 0. 918 between healthy leaves,and between the same diseased leaves. However,the values were all decreased between healthy and diseased leaves,and among different diseased leaves. The preprocessed original,first derivative and second derivative spectra in the range of 1 200- 700 cm- 1were chosen to evaluated principal component analysis( PCA) and hierarchical cluster analysis( HCA),respectively. The performance of the overall accuracy of PCA was 92.5%,which were better than original dataset and first derivative dataset. HCA by selecting second derivative dataset yield about 90% accuracy. This study proved that FTIR spectroscopy could be detected citrus diseases quickly and accurately.Xingxiang ZHAO Gang LIU Weixing LI Xiaohua Wang Jianming HAO Xiangping ZHOU 2014Asian Agricultural Research2014,6,1:0
12Study on Diseased Peanut Leaves by Fourier Transform Infrared Spectroscopy显示文摘[Objective] The paper was to study the application of Fourier transform infrared spectroscopy(FTIR technology) in identification of peanut diseases.[Method] By using FTIR technology,combined with the methods of principal component analysis and hierarchical cluster analysis,the healthy leaves and three kinds of diseased leaves (cercospora black spot,cercospora brown spot and web blotch) were identified in the paper. [Result] IR spectra of both diseased and healthy samples were similar,but tiny differences in wave-numbers and absorption intensities of peaks were observed in the range of 1 750-800 cm-1. Significant differences were found in second derivative spectra in the range of 3 600-2 800 and 1 750-650 cm-1which were selected to perform principle component and hierarchical cluster analysis. Three principal components had the cumulative contribution rate of 94. 9%; the correct rate of principal component analysis for classification was 100% and the correct rate of hierarchical cluster analysis for identification reached 94. 6%. [Conclusion] Fourier transform infrared spectroscopy has a potential to be developed as a powerful means for identification of crop diseases.Ou Quanhong Zhao Xingxiang Hao Jianming Zhou Xiangping Liu Gang Li Lun Zhang Li Wen Yuanbin 2013Plant Diseases and Pests2013,4,3:0

14Migration of ammonium nitrogen in ion-absorbed rare earth soils during and post in situ mining: a column study and numerical simulation analysis显示文摘Ion-absorbed rare earth mines,leached in situ,retain a large amount of ammonium nitrogen(NH4–N)that continuously releases into the surrounding environments.However,quantitative descriptions and predictions of the transport of NH4–N across mining area with hill slopes are not fully established.Here,laboratory column experiments were designed with an inclined slope(a sand box)to examine the spatial temporal transport of NH4–N in soils collected from the ionic rare earth elements(REE)mining area.An HYDRUS-2D model simulation of the experimental data over time showed that soils had a strong adsorption capacity toward NH4–N.Chemical non-equilibrium model(CNEM)could well simulate the transport of NH4–N through the soil-packed columns.The simulation of the transport-adsorption processes at three flow rates of leaching agents revealed that low flow rate enabled a longer residence time and an increased NH4-N adsorption,but reduced the extraction efficiency for REE.During the subsequent rainwater washing process,the presence of slope resulted in the leaching of NH4–N on the surface of the slope,while the leaching of NH4–N deep inside the column was inhibited.Furthermore,the high-intensity rainfall significantly increased the leaching,highlighting the importance of considering the impact of extreme weather conditions during the leaching process.Overall,our study advances the understanding of the transport of NH4–N in mining area with hills,the impact of flow rates of leaching agents and precipitation intensities,and presents as a feasible modeling method to evaluate the environmental risks of NH4–N pollution during and post REE in situ mining activities.Gaosheng Xi Xiaojiang Gao Ming Zhou Xiangmei Zhai Ming Chen Xingxiang Wang Xiaoying Yang Zezhen Pan Zimeng Wang 2023Frontiers of Environmental Science & Engineering2023,17,8:0
