1Species spatial distributions in a warm-temperate deciduous broad-leaved forest in China显示文摘Spatial distribution is fundamental for understanding species coexistence mechanisms in forest communities.Here we comprehensively explored fine-scale spatial patterns of tree species in a secondary warm-temperate deciduous broad-leaved forest community in north China.Aggregated distribution patterns were predominant.Species functional traits had no significant effects on their spatial patterns.The aggregation intensity decreased with increasing DBH and abundance.The multivariate linear stepwise regression showed that abundance and maximum DBH were correlated with the aggregation intensity.Our results partially confirm that species attributes(abundance,DBH)and habitat heterogeneity may primarily contribute to spatial patterns and species coexistence in this secondary forest.Huiyan Gu Jiaxin Li Guang Qi Shunzhong Wang 2020Journal of Forestry Research2020,31,4:2

8Hydrogen storage by liquid organic hydrogen carriers:Catalyst,renewable carrier,and technology--A review显示文摘Hydrogen has attracted widespread attention as a carbon-neutral energy source,but developing efficient and safe hydrogen storage technologies remains a huge challenge.Recently,liquid organic hydrogen carriers(LOHCs)technology has shown great potential for efficient and stable hydrogen storage and transport.This technology allows for safe and economical large-scale transoceanic transportation and long-cycle hydrogen storage.In particular,traditional organic hydrogen storage liquids are derived from nonrenewable fossil fuels through costly refining procedures,resulting in unavoidable environmental contamination.Biomass holds great promise for the preparation of LOHCs due to its unique carbon-balance properties and feasibility to manufacture aromatic and nitrogen-doped compounds.According to recent studies,almost 100%conversion and 92% yield of benzene could be obtained through advanced biomass conversion technologies,showing great potential in preparing biomass-based LOHCs.Overall,the present LOHCs systems and their unique applications are introduced in this review,and the technical paths are summarized.Furthermore,this paper provides an outlook on the future development of LOHCs technology,focusing on biomass-derived aromatic and N-doped compounds and their applications in hydrogen storage.Chenyang Chu Kai Wu Bingbing Luo Qi Cao Huiyan Zhang 2023Carbon Resources Conversion2023,6,4:1

12Etiological characteristics of influenza-like illness in Jiangsu province from 2012 to 2016显示文摘Influenza-like illness(ILI)is an acute respiratory infection caused by various pathogens.However,the epidemiologic characteristics of ILI pathogens in Jiangsu province are unclear.To better understand the ILI etiology,the characteristics of the pathogens from nasopharyngeal swab samples of patients with ILI collected from 2012 to 2016 in 6 hospitals in Jiangsu province were studied.The pathogens,including influenza virus,respiratory syncytial virus(RSV),rhinovirus(HRV),adenovirus(ADV),herpes simplex virus(HSV),human coronavirus(hCoV),Streptococcus pneumoniae and Haemophilus influenzae,were detected by real-time PCR.At least one pathogen was identified in 1334 of the patients(40.23%).Among viruses,HRV,influenza A virus(Flu A),ADV and RSV were the most frequently detected.ADV was the only pathogen that was distributed evenly in different years and regions(P>0.05).The etiological distribution varied in different age groups.Streptococcus pneumoniae was the most common pathogen in co-infections with a co-detection rate of 64.57%(319/494).The spectrum of etiologies could help to estimate disease burden and provide guidance for vaccination.Ke Xu Xiang Huo Rongqiang Zu Shenjiao Wang Yuanfang Qin Qigang Dai Xian Qi Huiyan Yu Lilin Chen Lei Hong Yangting Xu Qianhua Yi Weixiang Wang Xuan Wang Wenjun Dai Jie Zha Weining Han Changjun Bao 2019The Journal of Biomedical Research2019,33,6:0
13In-situ study for the elastic structure evolutions of threedimensional Ir-O framework during the oxygen evolution reaction in acid显示文摘Understanding the dynamic structural and chemical evolutions at the catalyst-electrolyte interfaces is crucial for the development of active and stable electrocatalysts.In this work,β-Li_(2)IrO_(3)is employed as a model catalyst for the oxygen evolution reaction(OER).Its elastic three-dimensional Ir-O framework enables us to investigate the Li^(+)cation dissolution-induced structure evolutions and the formation mechanism of amorphous IrO_(x)species.Electrochemical measurements by rotating ring disk electrode(RRDE)reveal that up to 60%of the measured OER current can be ascribed to catalyst degradation.A series of in-situ X-ray diffraction spectroscopy(XRD),X-ray absorption spectroscopy(XAS),and Raman spectroscopy are conducted.Structure vibration is observed with oxidation states of Ir being reduced abnormally during OER at high potentials.It’s hypothesized that the reversible proton intercalations are responsible for the Ir turn-over mechanism.Results of this work demonstrate a stable and elastic iridate structure and reveal the initial catalyst degradation behaviors during OER in acid media.Jun Qi Xinyu Zhong Huiyan Zeng Chao Wang Zhongfei Liu Jiajun Chen Long Gu Enna Hong Mengxian Li Jiong Li Chunzhen Yang 2023Nano Research2023,16,7:0
14Estimation of the actual disease burden of human H7N9 infection in Jiangsu of eastern China from March 2013 to September 2017显示文摘The actual incidence of human H7N9 infection is supposed to be much higher than the documented laboratoryconfirmed cases.In this study,we estimated the number of the actual H7N9 cases in Jiangsu,China using a probabilistic multiplier model.Then,disability adjusted life years(DALYs),direct and indirect economic loss caused by this disease were calculated and analyzed.Till September 2017,the estimated total number of H7N9 cases was 2952[median,90%probability range(PR):1487-22094],which was 11.8 times(5.9-88.4)as large as the reported number.The median morbidity was estimated to be 4(90%PR:2-29)per 100000 population.The total DALYs loss was 16548 years,and the total economic loss(direct and indirect)was estimated to be RMB 1044618758(US$16.7 M).The average economic loss for per case and for per year was RMB 353868(US$56440)and RMB 232137502(US$37.0 M),respectively.The actual burden of human H7N9 infections was much heavier than what was documented.Our study provided an approach to estimate actual burden of infectious diseases using laboratory-confirmation.Haodi Huang Wang Ma Ke Xu Keith Dear Huiyan Yu Xian Qi Changjun Bao Minghao Zhou Xiang Huo 2019The Journal of Biomedical Research2019,33,5:0
