| 1 | Impact of nitrogen addition on plant community in a semi-arid temperate steppe in China显示文摘Increased nitrogen (N) deposition will often lead to a decline in species richness in grassland ecosystems but the shifts in functional groups and plant traits are still poorly understood in China.A field experiment was conducted at Duolun,Inner Mongolia,China,to investigate the effects of N addition on a temperate steppe ecosystem.Six N levels (0,3,6,12,24,and 48 g N/(m 2 a)) were added as three applications per year from 2005 to 2010.Enhanced N deposition,even as little as 3 g N/(m 2 a) above ambient N deposition (1.2 g N/(m 2 a)),led to a decline in species richness of the whole community.Increasing N addition can significantly stimulate aboveground biomass of perennial bunchgrasses (PB) but decrease perennial forbs (PF),and induce a slight change in the biomass of shrubs and semi-shrubs (SS).The biomass of annuals (AS) and perennial rhizome grasses (PR) accounts for only a small part of the total biomass.Species richness of PF decreased significantly with increasing N addition rate but there was a little change in the other functional groups.PB,as the dominant functional group,has a relatively higher height than others.Differences in the response of each functional group to N addition have site-specific and species-specific characteristics.We initially infer that N enrichment stimulated the growth of PB,which further suppressed the growth of other functional groups. | Ling SONG XueMei BAO XueJun LIU FuSuo ZHANG | 2012 | Journal of Arid Land2012,4,1: | 18 |
| 2 | Piezoluminescent devices by designing array structures显示文摘Mechanoluminescence has attracted increasing attentions because it can convert the kinetic energy during human daily motions into light to be used in sensors and displays. However, its practical applications are still hindered by the weak brightness and limited color while under large forces. Herein, we developed novel piezoluminescent devices(PLDs) which could effectively emit visible light under low pressing forces through the stress-concentration and enhancing deformation on the basis of carefully-designed array structures. The emitting colors were also tunable by using bilayer luminescent film under different pressures. This work not only provides a new strategy to effectively harvest mechanical energy into light,but also presents a scalable, low-cost and color-tunable PLD which shows great potentials in various applications such as luminescent floors, shoes and stress-activated displays. | Luke Bao Xiaojie Xu Yong Zuo Jing Zhang Fei Liu Yifan Yang Fan Xu Xuemei Sun Huisheng Peng | 2019 | Science Bulletin2019,64,3: | 5 |
| 3 | Day-ahead scheduling of large numbers of thermostatically controlled loads based on equivalent energy storage model显示文摘Due to their heat/cool storage characteristics, thermostatically controlled loads(TCLs) play an important role in demand response programmers. However, the modeling of the heat/cool storage characteristic of large numbers of TCLs is not simple. In this paper, the heat exchange power is adopted to calculate the power instead of the average power, and the relationship between the heat exchange power and energy storage is considered to develop an equivalent storage model, based on which the time-varying power constraints and the energy storage constraints are developed to establish the overall day-ahead schedulingmodel. Finally, the proposed scheduling method is verified using the simulation results of a six-bus system. | Peipei CHEN Yu-Qing BAO Xuemei ZHU Jinlong ZHANG Minqiang HU | 2019 | Journal of Modern Power Systems and Clean Energy2019,7,3: | 3 |
| 4 | Evolutionary transition between invertebrates and vertebrates via methylation reprogramming in embryogenesis显示文摘Major evolutionary transitions are enigmas,and the most notable enigma is between invertebrates and vertebrates,with numerous spectacular innovations.To search for the molecular connections involved,we asked whether global epigenetic changes may offer a clue by surveying the inheritance and reprogramming of parental DNA methylation across metazoans.We focused on gametes and early embryos,where the methylomes are known to evolve divergently between fish and mammals.Here,we find that methylome reprogramming during embryogenesis occurs neither in pre-bilaterians such as cnidarians nor in protostomes such as insects,but clearly presents in deuterostomes such as echinoderms and invertebrate chordates,and then becomes more evident in vertebrates.Functional association analysis suggests that DNA methylation reprogramming is associated with development,reproduction and adaptive immunity for vertebrates,but not for invertebrates.Interestingly,the single HOX cluster of invertebrates maintains unmethylated status in all stages examined.In contrast,the multiple HOX clusters show dramatic dynamics of DNA methylation during vertebrate embryogenesis.Notably,the methylation dynamics of HOX clusters are associated with their spatiotemporal expression in mammals.Our study reveals that DNA methylation reprogramming has evolved dramatically during animal evolution,especially after the evolutionary transitions from invertebrates to vertebrates,and then to mammals. | Xiaocui Xu Guoqiang Li Congru Li Jing Zhang Qiang Wang David KSimmons Xuepeng Chen Naveen Wijesena Wei Zhu Zhanyang Wang Zhenhua Wang Bao Ju Weimin Ci Xuemei Lu Daqi Yu Qian-fei Wang Neelakanteswar Aluru Paola Oliveri Yong EZhang Mark QMartindale Jiang Liu | 2019 | National Science Review2019,6,5: | 2 |
| 5 | Control Parameter Optimization of Thermostatically Controlled Loads Using a Modified State-queuing Model显示文摘Thermostatically controlled loads(TCLs)are one of the best candidates to participate in direct load control(DLC).However,little attention is given to the parameter optimization of the TCLs control system due to the complexity of the TCLs’dynamics.In this paper,the parameters of the feedback control system based on the direct compressor control mechanism(DCCM)are optimized using the modified state-queuing(SQ)model,which can provide good characterizaton and greatly simplifies the dynamics of the TCLs.The simulation results verify the effectiveness of the proposed method. | Yuqing Bao Peipei Chen Minqiang Hu Xuemei Zhu | 2020 | CSEE Journal of Power and Energy Systems2020,6,2: | 2 |

| 10 | Genetic Architecture of Childhood Kidney and Urological Diseases in China显示文摘Kidney disease is manifested in a wide variety of phenotypes,many of which have an important hereditary component.To delineate the genotypic and phenotypic spectrum of pediatric nephropathy,a multicenter registration system is being imple-mented based on the Chinese Children Genetic Kidney Disease Database(CCGKDD).In this study,all the patients with kidney and urological diseases were recruited from 2014 to 2020.Genetic analysis was conducted using exome sequencing for families with multiple affected individuals with nephropathy or clinical suspicion of a genetic kidney disease owing to early-onset or extrarenal features.The genetic diagnosis was confirmed in 883 of 2256(39.1%)patients from 23 provinces in China.Phenotypic profiles showed that the primary diagnosis included steroid-resistant nephrotic syndrome(SRNS,23.5%),glomerulonephritis(GN,32.2%),congenital anomalies of the kidney and urinary tract(CAKUT,21.2%),cystic renal disease(3.9%),renal calcinosis/stone(3.6%),tubulopathy(9.7%),and chronic kidney disease of unknown etiology(CKDu,5.8%).The pathogenic variants of 105 monogenetic disorders were identified.Ten distinct genomic disorders were identified as pathogenic copy number variants(CNVs)in 11 patients.The diagnostic yield differed by subgroups,and was highest in those with cystic renal disease(66.3%),followed by tubulopathy(58.4%),GN(57.7%),CKDu(43.5%),SRNS(29.2%),renal calcinosis/stone(29.3%)and CAKUT(8.6%).Reverse phenotyping permitted correct identification in 40 cases with clinical reassessment and unexpected genetic conditions.We present the results of the largest cohort of children with kidney disease in China where diagnostic exome sequencing was performed.Our data demonstrate the utility of family-based exome sequencing,and indicate that the combined analysis of genotype and phenotype based on the national patient registry is pivotal to the genetic diagnosis of kidney disease. | Ye Fang Hua Shi Tianchao Xiang Jiaojiao Liu Jialu Liu Xiaoshan Tang Xiaoyan Fang Jing Chen Yihui Zhai Qian Shen Guomin Li Li Sun Yunli Bi Xiang Wang Yanyan Qian Bingbing Wu Huijun Wang Wenhao Zhou Duan Ma Jianhua Mao Xiaoyun Jiang Shuzhen Sun Ying Shen Xiaorong Liu Aihua Zhang Xiaowen Wang Wenyan Huang Qiu Li Mo Wang Xiaojie Gao Yubin Wu Fang Deng Ruifeng Zhang Cuihua Liu Li Yu Jieqiu Zhuang Qing Sun Xiqiang Dang Haitao Bai Ying Zhu Siguang Lu Bili Zhang Xiaoshan Shao Xuemei Liu Mei Han Lijun Zhao Yuling Liu Jian Gao Ying Bao Dongfeng Zhang Qingshan Ma Liping Zhao Zhengkun Xia Biao Lu Yulong Wang Mengzhun Zhao Jianjiang Zhang Shan Jian Guohua He Huifeng Zhang Bo Zhao Xiaohua LI Feiyan Wang Yufeng Li Hongtao Zhu Xinhui Luo Jinghai Li Jia Rao Hong Xu | 2021 | Phenomics2021,1,3: | 0 |
| 11 | Spectrum of turbulent-boundary-layer fluctuation pressure and response of a polyvinylidence fluoride hydrophone显示文摘The point power spectrum density and the wavenumber frequency spectrum density of turbulent - boundary- layer fluctuation pressure were measured in water-tunnel by use of a 8 mm hydrophone and a 20-element array, respectively. The non-dimensional representation of measured point power spectrum coincides with the measured results by Bull M. K. et. al. in wind tunnel. The convection peak can be seen clearly in the measured wavenumber frequency spectrum and the convection velocity can be calculated from the location of the convection peak. The response spectrum of a polyvinylidence fluoride (PVDF) hydrophone, which receiving area is 100 mm× 60 nun, was also measured. By comparing it with the response spectrtum of the 8 mm hydrophone, it is shown that the PVDF hyrdophone has a strong wavenumber filtering effect on turbulent - boundary-layer pressure fluctuation. | GE Huiliang (State Key Lab. of Oceanic Acoustics, Ha-on Applied Acoustic Institute Hanggzhou 310012) HE Zuoyong (Harbin Engineering University Harbin 150001) BAO Xuemei (State Keg Lab. of Oceanic Acoustics, Hangzhou Applied Acoustic Institute Hanggzhou 31 | 2001 | Chinese Journal of Acoustics2001,20,2: | 0 |
