| 1 | Photochemical pollution in Lanzhou, China - A case study显示文摘The photochemical air pollution in Xigu district of Lanshou city, Gansu Province was studied during a period of 1981-1984. The extremely high NMHC/NOx ratio and ozone level elevation after rain have been noticed. A series of outdoor and indoor reaction chamber simulation experiments conducted in order to understand the specific conditions. The ozone formation under NMHC/NOx condition and the possible reason for high ozone concentration after rain are discussed. | Tang Xiaoyan , Li Jinglong, Dong ZhenXing, Wang Yuying,Wang Wenxing , Qi Liwen, Liu Xiling, Zhang Yutian, Zhang Xuejin,Tian Bingshen, Jin Suwen , Yang Lingqing and Zhang Yixin Department of Technical Physics,Peking University, Beijing, China.

| 2 | Identification and screening of nitrogenefficient cotton genotypes under low and normal nitrogen environments at the seedling stage显示文摘Background: Large quantities of nitrogen(N) fertilizer applied to cotton cropping systems support high yields but cause adverse environmental impacts such as N_20 emission and water eutrophication. The development of cotton cultivars with higher N use efficiencies suitable for low-N conditions is therefore important for sustainable production. In this study, we evaluated 100 cotton genotypes in 2016 for N use efficiency and related traits at the seedling stage.Methods: Sand culture experiment was conducted with low N levels(0.01 g·kg^(-1)) or normal N levels(0.1 g·kg^(-1)).We investigated plant height, SPAD value(soil plant analysis development chlorophyll meter), dry weight, N accumulation, N utilization efficiency, and N uptake efficiency. Through descriptive statistics, principal component analysis and heatmap clustering analysis, we confirmed the evaluation index system of N-efficient genotypes and the classification of N-efficient genotypes.Results: Significant differences were observed among N levels and genotypes for all agronomic traits and N levels.Coefficients of variation varied greatly and ranged from 6.7~28.8 and 7.4~20.8 under low-N and normal-N treatment, respectively. All traits showed highly significant positive correlations with each other, except SPAD value.The principal components under both N levels were similar, showing that total dry weight, aboveground dry weight, total N accumulation, and N uptake efficiency were important components. We confirmed these four traits as suitable screening indexes for low N tolerance. Based on the results of heatmap clustering and scatter diagram analysis of N efficiency value, 10 genotypes were found low-N tolerant, in which five varieties were inefficient under both low and normal N conditions, while four varieties were found efficient under low-N conditions but inefficient under normal-N conditions. Only one variety was efficient under both low and normal-N conditions. Meanwhile, 20 genotypes were identified as low-N sensitive ones, in which 19 genotypes were inefficient under low-N conditions but efficient under normal-N conditions, one variety was inefficient under both low and normal-N conditions.Conclusion: We preliminarily identified Kashi as a low-N tolerant and N-efficient cotton genotype, and CCRI 64 as a lowN sensitive and N-inefficient cotton genotype. Further studies should be carried out to verify the yield and heritability effect of specific genotypes in the field. | ZHANG Hengheng FU Xiaoqiong WANG Xiangru GUI Huiping DONG Qiang PANG Nianchang WANG Zhun ZHANG Xiling SONG Meizhen | 2018 | Journal of Cotton Research2018，1，2： | 9 |
| 3 | Screening and evaluation of reliable traits of upland cotton(Gossypium hirsutum L.)genotypes for salt tolerance at the seedling growth stage显示文摘Background:Salt stress significantly inhibits the growth,development,and productivity of cotton because of osmotic,ionic,and oxidative stresses.Therefore,the screening and development of salt tolerant cotton cultivars is a key issue towards sustainable agriculture.This study subjected 11 upland cotton genotypes at the seedling growth stage to five different salt concentrations and evaluated their salt tolerance and reliable traits.Results:Several morpho-physiological traits were measured after 10 days of salinity treatment and the salt tolerance performance varied significantly among the tested cotton genotypes.The optimal Na Cl concentration for the evaluation of salt tolerance was 200 mmol·L-1.Membership function value and salt tolerance index were used to identify the most consistent salt tolerance traits.Leaf relative water content and photosynthesis were identified as reliable indicators for salt tolerance at the seedling stage.All considered traits related to salt tolerance indices were significantly and positively correlated with each other except for malondialdehyde.Cluster heat map analysis based on the morpho-physiological salt tolerance-indices clearly discriminated the 11 cotton genotypes into three different salt tolerance clusters.Cluster I represented the salt-tolerant genotypes(Z9807,Z0228,and Z7526)whereas clusters II(Z0710,Z7514,Z1910,and Z7516)and III(Z0102,Z7780,Z9648,and Z9612)represented moderately salttolerant and salt-sensitive genotypes,respectively.Conclusions:A hydroponic screening system was established.Leaf relative water content and photosynthesis were identified as two reliable traits that adequately represented the salt tolerance of cotton genotypes at the seedling growth stage.Furthermore,three salt-tolerant genotypes were identified,which might be used as genetic resources for the salt-tolerance breeding of cotton. | SIKDER Ripon Kumar WANG Xiangru JIN Dingsha ZHANG Hengheng GUI Huiping DONG Qiang PANG Nianchang ZHANG Xiling SONG Meizhen | 2020 | Journal of Cotton Research2020，3，2： | 5 |

| 6 | Relationship between full-thickness macular hole and retinal break/lattice degeneration显示文摘Background: The purpose is to investigate the relationship between full-thickness macular hole(MH) and retinal break(RB) and/or lattice degeneration.Methods: Patients diagnosed as full-thickness MH and referred to Dr. Lin Lu from January 2009 to December 2013 were evaluated. All patients underwent general ophthalmologic examinations, fundus examination and optical coherence tomography(OCT). The RB and/or lattice degeneration were recorded.Results: Totally 183 eyes of 167 patients were included. The sex ratio of men to women was 1:2.88. A total of 17 eyes were pseudophakic and 166 eyes were phakic. RB and/or lattice degeneration were found in 62 eyes(33.88%). The prevalence of RB and/or lattice degeneration was similar between men and women(P=0.344>0.05). There was no statistical difference between the pseudophakic eyes and phakic eyes(P=0.138>0.05). All of the RB and/or lattice degeneration were located near or anterior to the equator. The inferior quadrants and the vertical meridian were af ected more often than the superior quadrants and the horizontal meridian.Conclusions: We identified a high incidence of RB/lattice degeneration in cases of full-thickness MH. Carefully examination of the peripheral retina and prophylactic treatment of RB and/or lattice degeneration are critical. | Jinglin Zhang Yonghao Li Xiujuan Zhao Yu Cai Xiling Yu Lin Lu | 2015 | Eye Science2015，30，4： | 2 |
| 7 | An Outbreak of the SARS-CoV-2 Omicron Variant BA.1—Zhuhai City,Guangdong Province,China,January 13,2022显示文摘On January 13,2022,Zhuhai CDC received a notification that a coronavirus disease 2019(COVID-19)case was found in the fever clinic in nearby Zhongshan City.Zhuhai CDC promptly carried out large-scale population screening in three nearby counties.A total of 4 COVID-19 cases were found in Nanping County.34 cases were screened from close contacts,and 2 cases were reported from close contacts in other cities of Guangdong Province.The 20 cases were sequenced by Guangdong CDC and identified as the variant of concern(VOC)/Omicron variant BA.1.Since January 14,Zhuhai has carried out 8 rounds of nucleic acid screening for COVID-19 in the county where the cases occurred.Four large-scale nucleic acid screening tests for COVID-19 were conducted across the city,and no new community cases were reported after January 15. | Feng Ruan Xuebao Zhang Songjian Xiao Xihe Ni Xiling Yin Zhongwen Ye Guorong Chen Tingting Zhu Zeling Chen Gang Yao Long Chen Sichen Huang Huitao Huang Yi Zhou Heyan Wu Hui Huang Kejing Zhu Shanzi Huang Xiaoou Tang Min Kang Bosheng Li Wenhua Mei | 2022 | China CDC weekly2022，4，30： | 2 |

| 9 | Chromosome-level Genomes Reveal the Genetic Basis of Descending Dysploidy and Sex Determination in Morus Plants显示文摘Multiple plant lineages have independently evolved sex chromosomes and variable karyotypes to maintain their sessile lifestyles through constant biological innovation.Morus notabilis,a dioecious mulberry species,has the fewest chromosomes among Morus spp.,but the genetic basis of sex determination and karyotype evolution in this species has not been identified.In this study,three high-quality genome assemblies were generated for Morus spp.[including dioecious M.notabilis(male and female)and Morus yunnanensis(female)]with genome sizes of 301–329 Mb and were grouped into six pseudochromosomes.Using a combination of genomic approaches,we found that the putative ancestral karyotype of Morus species was close to 14 protochromosomes,and that several chromosome fusion events resulted in descending dysploidy(2n=2x=12).We also characterized a~6.2-Mb sex-determining region on chromosome 3.Four potential male-specific genes,a partially duplicated DNA helicase gene(named MSDH)and three Ty3_Gypsy long terminal repeat retrotransposons(named MSTG1/2/3),were identified in the Y-linked area and considered to be strong candidate genes for sex determination or differentiation.Population genomic analysis showed that Guangdong accessions in China were genetically similar to Japanese accessions of mulberry.In addition,genomic areas containing selective sweeps that distinguish domesticated mulberry from wild populations in terms of flowering and disease resistance were identified.Our study provides an important genetic resource for sex identification research and molecular breeding in mulberry. | Zhongqiang Xia Xuelei Dai Wei Fan Changying Liu Meirong Zhang Peipei Bian Yuping Zhou Liang Li Baozhong Zhu Shuman Liu Zhengang Li Xiling Wang Maode Yu Zhonghuai Xiang Yu Jiang Aichun Zhao | 2022 | Genomics, Proteomics & Bioinformatics2022，20，6： | 1 |

| 13 | Chromosome-level genome assemblies of five Prunus species and genome-wide association studies for key agronomic traits in peach显示文摘Prunus species include many important perennial fruit crops,such as peach,plum,apricot,and related wild species.Here,we report de novo genome assemblies for five species,including the cultivated species peach(Prunus persica),plum(Prunus salicina),and apricot(Prunus armeniaca),and the wild peach species Tibetan peach(Prunus mira)and Chinese wild peach(Prunus davidiana).The genomes ranged from 240 to 276 Mb in size,with contig N50 values of 2.27−8.30Mb and 25,333−27,826 protein-coding gene models.As the phylogenetic tree shows,plum diverged from its common ancestor with peach,wild peach species,and apricot~7 million years ago(MYA).We analyzed whole-genome resequencing data of 417 peach accessions,called 3,749,618 high-quality SNPs,577,154 small indels,31,800 deletions,duplications,and inversions,and 32,338 insertions,and performed a structural variant-based genome-wide association study(GWAS)of key agricultural traits.From our GWAS data,we identified a locus associated with a fruit shape corresponding to the OVATE transcription factor,where a large inversion event correlates with higher OVATE expression in flat-shaped accessions.Furthermore,a GWAS revealed a NAC transcription factor associated with fruit developmental timing that is linked to a tandem repeat variant and elevated NAC expression in early-ripening accessions.We also identified a locus encoding microRNA172d,where insertion of a transposable element into its promoter was found in double-flower accessions.Thus,our efforts have suggested roles for OVATE,a NAC transcription factor,and microRNA172d in fruit shape,fruit development period,and floral morphology,respectively,that can be connected to traits in other crops,thereby demonstrating the importance of parallel evolution in the diversification of several commercially important domesticated species.In general,these genomic resources will facilitate functional genomics,evolutionary research,and agronomic improvement of these five and other Prunus species.We believe that structural variant-based GWASs can also be used in other plants,animal species,and humans and be combined with deep sequencing GWASs to precisely identify candidate genes and genetic architecture components. | Qiuping Tan Sen Li Yuzheng Zhang Min Chen Binbin Wen Shan Jiang Xiude Chen Xiling Fu Dongmei Li Hongyu Wu Yong Wang Wei Xiao Ling Li | 2021 | Horticulture Research2021，8，1： | 1 |

| 15 | Coking behaviors and kinetics on HZSM-5/SAPO-34 catalysts for conversion of ethanol to propylene显示文摘The coke deposition on HZSM-5/SAPO-34 composite catalysts has been studied in the conversion of ethanol to propylene. The HZSM-5/SAPO-34 composite catalysts were synthesized by hydrothermal method(ZS-HS) and fully blending(ZS-MM). The used catalysts were characterized by XRD, N_2 adsorption–desorption, TGA, TPO, elemental analysis, FTIR and XPS. The coking kinetics on both ZS-HS and ZS-MM has been investigated and their coking rate equations were obtained. The used ZS-MM catalyst had higher amount of coke and lower nC:nHthan the used ZS-HS. 90% of the coke was deposited in the micropores of ZS-HS, while almost 45% of the coke located in the micropores of ZS-MM. The coke deposited on ZS-HS catalyst was mainly graphite-like carbon species, whereas dehydrogenated coke species was the major on ZS-MM. The coking activation energy of ZS-MM was lower than that of ZS-HS, and the coking rate on ZS-MM was faster than on ZS-HS. In addition, the regeneration of ZS-MM catalyst showed that it had a good hydrothermal stability. The differences on coking behaviors on the two catalysts were due to their different acidic properties and textures. | Ting Bai Xin Zhang Feng Wang Wenting Qu Xiling Liu Chao Duan | 2016 | Journal of Energy Chemistry2016，25，3： | 1 |

| 17 | New Method for Computer Identification Through Electromagnetic Radiation显示文摘The electromagnetic waves emitted from devices can be a source of information leakage and can cause electromagnetic compatibility(EMC)problems.Electromagnetic radiation signals from computer displays can be a security risk if they are intercepted and reconstructed.In addition,the leaks may reveal the hardware information of the computer,which is more important for some attackers,protectors and security inspection workers.In this paper,we propose a statistical distribution based algorithm(SD algorithm)to extracted eigenvalues from electromagnetic radiate video signals,and then classified computers by using classifier based on Bayesian and SVM.We can identify computers automatically and accurately through electromagnetic radiation by using the algorithm in our experiment environment. | Jun Shi Zhujun Zhang Yangyang Li Rui Wang Hao Shi Xile Li | 2018 | Computers, Materials & Continua2018，，10： | 1 |
