| 2 | On the adjacent-vertex-strongly-distinguishing total coloring of graphs显示文摘For any vertex u∈V(G), let TN(U)={u}∪{uv|uv∈E(G), v∈v(G)}∪{v∈v(G)|uv∈E(G)}and let f be a total k-coloring of G. The total-color neighbor of a vertex u of G is the color set Cf(u)={f(x)|x∈TN(U)}. For any two adjacent vertices x and y of V(G)such that Cf(x)≠Cf(y), we refer to f as a k-avsdt-coloring of G('avsdt'is the abbreviation of'adjacent-vertex-strongly- distinguishing total'). The avsdt-coloring number of G, denoted by Xast(G), is the minimal number of colors required for a avsdt-coloring of G. In this paper, the avsdt-coloring numbers on some familiar graphs are studied, such as paths, cycles, complete graphs, complete bipartite graphs and so on. We proveΔ(G)+1≤Xast(G)≤Δ(G)+2 for any tree or unique cycle graph G. | ZHANG ZhongFu CHENG Hui YAO Bing LI JingWen CHEN XiangEn XU BaoGen | 2008 | Science China Mathematics2008,51,3: | 74 |
| 3 | D(β)-vertex-distinguishing total coloring of graphs显示文摘A new concept of the D(β)-vertex-distinguishing total coloring of graphs, i.e., the proper total coloring such that any two vertices whose distance is not larger than β have different color sets, where the color set of a vertex is the set composed of all colors of the vertex and the edges incident to it, is proposed in this paper. The D(2)-vertex-distinguishing total colorings of some special graphs are discussed, meanwhile, a conjecture and an open problem are presented. | ZHANG Zhongfu,LI Jingwen,CHEN Xiang’en,YAO Bing, WANG Wenjie & QIU Pengxiang Institute of Applied Mathematic, Lanzhou Jiaotong University, Lanzhou 730070, China College of Mathematics and Information Science, Northwest Normal University, Lanzhou 730070, China College of Information and Electrical Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China | 2006 | Science China Mathematics2006,49,10: | 54 |
| 4 | X-ray-charged bright persistent luminescence in NaYF_(4):Ln^(3+)@NaYF_(4) nanoparticles for multidimensional optical information storage显示文摘NaYF_(4):Ln^(3+),due to its outstanding upconversion characteristics,has become one of the most important luminescent nanomaterials in biological imaging,optical information storage,and anticounterfeiting applications.However,the large specific surface area of NaYF_(4):Ln^(3+)nanoparticles generally leads to serious nonradiative transitions,which may greatly hinder the discovery of new optical functionality with promising applications.In this paper,we report that monodispersed nanoscale NaYF_(4):Ln^(3+),unexpectedly,can also be an excellent persistent luminescent(PersL)material.The NaYF_(4):Ln^(3+)nanoparticles with surface-passivated core–shell structures exhibit intense X-ray-charged PersL and narrow-band emissions tunable from 480 to 1060 nm.A mechanism for PersL in NaYF_(4):Ln^(3+)is proposed by means of thermoluminescence measurements and host-referred binding energy(HRBE)scheme,which suggests that some lanthanide ions(such as Tb)may also act as effective electron traps to achieve intense PersL.The uniform and spherical NaYF_(4):Ln^(3+)nanoparticles are dispersible in solvents,thus enabling many applications that are not accessible for traditional PersL phosphors.A new 3-dimensional(2 dimensions of planar space and 1 dimension of wavelength)optical information-storage application is demonstrated by inkjet-printing multicolor PersL nanoparticles.The multicolor persistent luminescence,as an emerging and promising emissive mode in NaYF_(4):Ln^(3+),will provide great opportunities for nanomaterials to be applied to a wider range of fields. | Yixi Zhuang Dunrong Chen Wenjing Chen Wenxing Zhang Xin Su Renren Deng Zhongfu An Hongmin Chen Rong-Jun Xie | 2021 | Light(Science & Applications)2021,10,7: | 12 |

| 6 | Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world. | Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong | 2022 | Science China(Life Sciences)2022,65,9: | 9 |
| 7 | Potential and policy issues for sustainable development of wind power in China显示文摘This paper presents a macroscopic view on the prevailing policy and potential issues in respect of the sustainable wind power development in China.It starts by analyzing the characteristics of wind power resources and pin-pointing the relationship between the regulatory policies and various economic,taxation,legal and grid integration attributes relating to the wind power development.Then it follows by analyzing the status quo and capabilities of the wind power manufacturing industry in China including its operational efficiency and grid integration standards.The economic and environmental benefits are estimated by relating to the associated costing analysis in respect of the major contributing factors such as manufacturing,operational and financial factors.Results of the associated benefits analysis indicate that the use of the wind power generation helps to save a significant equivalent amount of standard coal consumption resulting to reduction of emission effectively.Finally,the potential of wind power development in China is shown to be affirmative and the sustainable energy policy is effectively implemented in China. | Zhongfu TAN H.W.NGAN Yang WU Huijuan ZHANG Yihang SONG Chao YU | 2013 | Journal of Modern Power Systems and Clean Energy2013,1,3: | 7 |
| 8 | Molecular dissection of plant height QTLs using recombinant inbred lines from hybrids between common wheat (Triticum aestivum L.) and spelt wheat (Triticum spelta L.)显示文摘In wheat, plant height is an important agronomic trait, and a number of quantitative trait loci (QTLs) controlling plant height have been located. In this study, using the conditional and unconditional QTL mapping methods, combined with data from five different growth stages over two years of field trials, the developmental behavior for plant height in wheat was dissected. Nine unconditional QTLs and 8 conditional QTLs were identified, of which 6 were detected by both methods. None of the 11 QTLs was detected at all of the 5 investigated developmental stages, but 7 QTLs were detected at certain stages in both years. Further analysis identified 9 unconditional QTLs at different stages, which could explain the phenotypic variation from 4.81% to 17.35%. It was noteworthy that one major QTL designated QHt-4B-2, which was located on chromosome 4B, was detected on May 18 and 25 in both years, and its genetic contributions to plant height ranged from 13.42% to 16.13%. Moreover, of the 8 conditional QTLs identified, six were detected in both years, in the order of QHt-3B→QHt-4B-1→QHt-4B-2→QHt-4D→QHt-5A and QHt-2B expressed at the same developmental stage. The results indicate that QTL expression during plant height development is selective and in a temporal order. | LIU Gang XU ShengBao NI ZhongFu XIE ChaoJie QIN DanDan LI Jing LU LaHu ZHANG JinPing PENG HuiRu SUN QiXin | 2011 | Chinese Science Bulletin2011,56,18: | 6 |
| 9 | HIV Prevention and Health Poverty Alleviation-Liangshan Prefecture,Sichuan Province,China,2017-2020显示文摘BACKGROUND Liangshan,officially the Liangshan Yi Autonomous Prefecture,is an autonomous prefecture occupying much of the southern portion of Sichuan Province.It has been a remote and deeply impoverished area and also has the largest population of ethnic Yi people in China(1).For many years,due to geographical environment conditions,traffic conditions,and other historic restrictions,the human immunodeficiency virus(HIV)epidemic in Liangshan Prefecture has become the focus of HIV prevention and control in China since the first acquired immunodeficiency syndrome(AIDS)case was reported in this area in 1995(2-3). | Zhongfu Liu Xuefeng Tang Yufen Liu Linglin Zhang Yihui Yang Yongli Zheng Weixin Liu Chunnong Jike Hong Mai Heying Fan Gang Yu Mengjie Han George F.Gao | 2021 | China CDC weekly2021,3,48: | 4 |
| 10 | Ectopic expression of VRT-A2 underlies the origin of Triticum polonicum and Triticum petropavlovskyi with long outer glumes and grains显示文摘Polish wheat (Triticum polonicum) is a unique tetraploid wheat species characterized by an elongated outer glume. The genetic control of the long-glume trait by a single semi-dominant locus, P1 (from Polish wheat), was established more than 100 years ago, but the underlying causal gene and molecular nature remain elusive. Here, we report the isolation of VRT-A2, encoding an SVP-clade MADS-box transcription factor, as the P1 candidate gene. Genetic evidence suggests that in T. polonicum, a naturally occurring sequence rearrangement in the intron-1 region of VRT-A2 leads to ectopic expression of VRT-A2 in floral organs where the long-glume phenotype appears. Interestingly, we found that the intron-1 region is a key ON/OFF molecular switch for VRT-A2 expression, not only because it recruits transcriptional repressors, but also because it confers intron-mediated transcriptional enhancement. Genotypic analyses using wheat accessions indicated that the P1 locus is likely derived from a single natural mutation in tetraploid wheat, which was subsequently inherited by hexaploid T. petropavlovskyi. Taken together, our findings highlight the promoter-proximal intron variation as a molecular basis for phenotypic differentiation, and thus species formation in Triticum plants. | Jing Liu Zhaoyan Chen Zhihui Wang Zhaoheng Zhang Xiaoming Xie Zihao Wang Lingling Chai Long Song Xuejiao Cheng Man Feng Xiaobo Wang Yanhong Liu Zhaorong Hu Jiewen Xing Zhenqi Su Huiru Peng Mingming Xin Yingyin Yao Weilong Guo Qixin Sun Jie Liu Zhongfu Ni | 2021 | Molecular Plant2021,14,9: | 4 |

| 12 | Systematic comparison of hydrogen production from fossil fuels and biomass resources显示文摘Fossil fuels are the main energy source to satisfy the worldwide energy demands.However,the energy demands are increasing and the supply of fossil fuels is decreasing,thus many countries are looking for other fuel sources.Differing from the traditional fuels,hydrogen is considered as one of the most promising energy sources due to its intrinsic features such as clean,efficient,safe and sustainable.Developing novel technologies for hydrogen production from renewable sources(such as biomass)becomes a core area for the investigation of hydrogen industry.Within this work,different pathways for hydrogen production including steam reforming,electrolysis,and biomass gasification have been systematically compared in terms of yield and cost.This comparison is unique since the systematic evaluation was conducted from many aspects for all the hydrogen production pathways,especially those by involving the biomass gasification that still lack of available literatures.The assessment methods involved energy analysis,exergy analysis and economic analysis.It was concluded that steam reforming remains the cheapest method of hydrogen production at 1.748$/kg,however,steam reforming is not an ideal process currently or for the future,gasification and electrolysis remains competitive with high yield but requires relatively high initial and annual expenditure.For biomass gasification,though its energy efficiency is lower than steam reforming,it has relatively higher mass yield,demonstrating the feasibility of this process for hydrogen production.Further for biomass gasification,the selection of correct feedstock is a key to maximize its yield,i.e.a yield of 82.47%is possible with corn stover fed gasification. | Kang Peng Gary Morrow Zhang Xiaolei Wang Tipeng Tan Zhongfu Jayant Agarwal | 2017 | International Journal of Agricultural and Biological Engineering2017,10,6: | 2 |
| 13 | Ectopic Overexpression of Wheat Adenosine Diphosphate-ribosylation Factor,TaARF,Increases Growth Rate in Arabidopsis显示文摘Differential gene expression between hybrids and their parents is considered to be associated with heterosis. However,the physiological functions and possible contribution to heterosis of these differentially expressed genes are unknown.We have isolated one hybrid upregulated gene encoding putative wheat ADP-ribosylation factor, designated TaARF. In thisstudy, real-time quantitative reverse transcription-polymerase chain reaction analysis indicated that the TaARF transcriptwas preferentially expressed in root, node and crown, and the accumulation of TaARF mRNA in hybrid was more than1.5-fold higher than that in two parents. In order to understand possible roles of the putative wheat ARF gene, TaARFwas overexpressed in Arabidopsis, and the transgenic plants were characterized. We show that ectopic overexpression ofTaARF in Arabidopsis leads to increased leaf area, increased growth rate and earlier transition to flowering, suggestingthat TaARF plays significant roles in growth and development. This study provides evidence demonstrating that TaARFplays important roles in gr owth and development and we speculate that the upregulated expression of this gene mightcontribute to the heterosis observed in wheat root and leaf growth. | Yingyin Yao Zhongfu Ni Jinkun Du Zongfu Han Yan Chen Qingbo Zhang Qixin Sun | 2009 | Journal of Integrative Plant Biology2009,51,1: | 2 |
| 14 | A segmentation method for processing greenhouse vegetable foliar disease symptom images显示文摘Uneven illumination and clutter background were the most challenging problems to segmentation of disease symptom images.In order to achieve robust segmentation,a method for processing greenhouse vegetable foliar disease symptom images was proposed in this paper.The segmentation method was based on a decision tree which was constructed by a two-step coarse-to-fine procedure.Firstly,a coarse decision tree was built by the CART(Classification and Regression Tree)algorithm with a feature subset.The feature subset consisted of color features that was selected by Pearson’s Rank correlations.Then,the coarse decision tree was optimized by pruning.Using the optimized decision tree,segmentation of disease symptom images was achieved by conducting pixel-wise classification.In order to evaluate the robustness and accuracy of the proposed method,an experiment was performed using greenhouse cucumber downy mildew images.Results showed that the proposed method achieved an overall accuracy of 90.67%,indicating that the method was able to obtain robust segmentation of disease symptom images. | Juncheng Ma Keming Du Feixiang Zheng Lingxian Zhang Zhongfu Sun | 2019 | Information Processing in Agriculture2019,6,2: | 2 |
| 15 | All-in-One Deposition to Synergistically Manipulate Perovskite Growth for High-Performance Solar Cell显示文摘Nonradiative recombination losses originating from crystallographic distortions and issues occurring upon interface formation are detrimental for the photovoltaic performance of perovskite solar cells.Herein,we incorporated a series of carbamide molecules(urea,biuret,or triuret)consisting of both Lewis base(-NH2)and Lewis acid(-C=O)groups into the perovskite precursor to simultaneously eliminate the bulk and interface defects.Depending on the different coordination ability with perovskite component,the incorporated molecules can either modify crystallization dynamics allowing for large crystal growth at low temperature(60℃),associate with antisite or undercoordinated ions for defect passivation,or accumulate at the surface as an energy cascade layer to enhance charge transfer,respectively.Synergistic benefits of the above functions can be obtained by rationally optimizing additive combinations in an all-in-one deposition method.As a result,a champion efficiency of 21.6%with prolonged operational stability was achieved in an inverted MAPbI3 perovskite solar cell by combining biuret and triuret additives.The simplified all-in-one fabrication procedure,adaptable to different types of perovskites in terms of pure MAPbI3,mixed perovskite,and all-inorganic perovskite,provides a cost-efficient and reproducible way to obtain high-performance inverted perovskite solar cells. | Yifan Lv Hui Zhang Jinpei Wang Libao Chen Lifang Bian Zhongfu An Zongyao Qian Guoqi Ren Jie Wu Frank Nuesch Wei Huang | 2020 | Research2020,,1: | 2 |
