| 2 | Remote sensing based monitoring of interannual variations in vegetation activity in China from 1982 to 2009显示文摘Terrestrial vegetation is one of the most important components of the Earth's land surface. Variations in terrestrial vegetation directly impact the Earth system's balance of material and energy. This paper describes detected variations in vegetation activity at a national scale for China based on nearly 30 years of remote sensing data derived from NOAA/AVHRR(1982–2006) and MODIS(2001–2009). Vegetation activity is analyzed for four regions covering agriculture, forests, grasslands, and China's Northwest region with sparse vegetation cover(including regions without vegetation). Relationships between variations in vegetation activity and climate change as well as agricultural production are also explored. The results show that vegetation activity has generally increased across large areas, especially during the most recent decade. The variations in vegetation activity have been driven primarily by human factors, especially in the southern forest region and the Northwest region with sparse vegetation cover. The results further show that the variations in vegetation activity have influenced agricultural production, but with a certain time lag. | LI Fei ZENG Yuan LI XiaoSong ZHAO QianJun WU BingFang | 2014 | Science China Earth Sciences2014，57，8： | 8 |
| 3 | A New Carbon and Oxygen Balance Model Based on Ecological Service of Urban Vegetation显示文摘The application of human induced oxygen consumption and carbon emission theory in urban region was summed up and on this base a new model of urban carbon and oxygen balance (UCOB) was constructed by calculating the carbon and oxygen fluxes. The purpose was to highlight the role of vegetation in urban ecosystems and evaluate the effects of various human activities on urban annual oxygen consumption and carbon emission. Hopefully,the model would be helpful in theory to keep the regional balance of carbon and oxygen,and provide guidance and support for urban vegetation planning in the future. To test the UCOB model,the Jimei District of Xiamen City,Fujian Province,China,a very typical urban region,was selected as a case study. The results turn out that Jimei′s vegetation service in oxygen emission and carbon sequestration could not meet the demand of the urban population,and more than 31.49 times of vegetation area should be added to meet the whole oxygen consumption in Jimei while 9.60 times of vegetation area are needed to meet the carbon sequestration targets. The results show that the new UCOB model is of a great potential to be applied to quantitative planning of urban vegetation and regional eco-compensation mechanisms. | YIN Kai ZHAO Qianjun LI Xuanqi CUI Shenghui HUA Lizhong LIN Tao | 2010 | Chinese Geographical Science2010，20，2： | 6 |
| 4 | Determination of water content in corn stover silage using near-infrared spectroscopy显示文摘The aim of this study was to evaluate the feasibility of utilizing near-infrared spectroscopy to determine the water content of corn stover silage across a wide range.The water contents of 208 samples were measured,and their corresponding near-infrared spectra were simultaneously collected.The effects of different preprocessing methods,such as derivation,standard normal variety(SNV),multiplicative scatter correction(MSC),and non-preprocessing methods for the obtained near-infrared spectra on the performance of calibration models were compared.The calibration models were established by modified partial least squares(MPLS)regression.The results showed that the calibration model developed from the successive preprocessing of MSC and first-order derivation(1-D)achieved the optimal performance.The correlation coefficients of the calibration and validation subset were 0.974 and 0.949,respectively,and the standard errors of the calibration and cross validation were 4.249% and 4.256%,respectively.External validation was performed on 60 samples.The correlation coefficient between the measured and predicted values of the calibration model was 0.973 and the prediction model’s relative percent deviation was 4.317.This indicated that the mathematical model of near-infrared spectroscopy predicted the water content in corn stover silage with high accuracy.The study showed that the near-infrared spectroscopy technology can be used for rapid and non-destructive testing across a wide range of water contents in the corn stover silage. | Maoqun Zhang Chao Zhao Qianjun Shao Zidong Yang Xuefen Zhang Xiaofeng Xu Muhammad Hassan | 2019 | International Journal of Agricultural and Biological Engineering2019，12，6： | 2 |
| 5 | Whole-genome sequencing reveals selection signals among Chinese,Pakistani,and Nepalese goats显示文摘The goat(Capra hircus)is one of the oldest domesticated animal species,with archeological evidence indicating that its earliest domestication from the wild ancestor(bezoar)occurred in the Fertile Crescent 10,000 calibrated calendar years ago(Zeder and Hesse,2000).A variety of well-adapted goat breeds with excellent economic traits have been selected artificially and naturally for human needs in China,Pakistan,and Nepal.For example,cashmere goat breeds produce fine cashmere wool and are mainly distributed on the Himalayan Plateau(e.g.,Nepal and Tibet)and in cold northern China(e.g.,Inner Mongolia and Liaoning).The Toggenburg dairy goat is the most productive breed of dairy goat and is distributed in at least 50 countries on all continents(Ferro et al.,2017).Pakistani ewes are reared mostly for meat and wool purposes,but some are used as dairy goats,such as the Bugi Toori goat and Pateri goat(Bilal et al.,2018).Additionally,indigenous goats of the southern Asian regions are well adapted to the local hot environment.Their unique traits and biodiversity serve as genetic resources that can be used for the artificial breeding of goats.Recently,several studies have provided patterns of genome-wide characteristics in goat populations to explore the underlying genetic basis of trait formation and environmental adaptability in China(Zhang et al.,2018),Pakistan(Kumar et al.,2018),and Nepal(Sasazaki et al.,2021),respectively.However,due to the proximity of these geographic regions,the profiles of genetic differences,gene flow,and common genes related to high trait performance between goat populations from China,Pakistan,and Nepal remain unclear. | Yefang Li Ying Gong Zhengkai Zhang Ling Li Xuexue Liu Xiaohong He Qianjun Zhao Yabin Pu Yuehui Ma Lin Jiang | 2023 | Journal of Genetics and Genomics2023，50，5： | 2 |
| 6 | Fe-porphyrin:A redox-related biosensor of hydrogen molecule显示文摘Hydrogen molecule(H_(2))exhibits broad-spectrum but microenvironment-dependent biomedical effects in varied oxidation stress-related diseases,but its molecular mechanism is unclear and its targeting molecule is unknown so far.Herein,we originally reveal that Fe-porphyrin is a H_(2)-targeted molecule.We have demonstrated that the oxidized Fe-porphyrin in both free and protein-confining states can self-catalyze the hydrogenation/reduction by reacting with H_(2)to catalytically scavenge∙OH,and can also catalytically hydrogenate to reduce CO_(2)into CO in the hypoxic microenvironment of in vitro simulation and in vivo tumor,confirming that Fe-porphyrin is a redox-related biosensor of H_(2)and H_(2)is an upstream signaling molecule of CO.These discoveries are favorable for deep understanding and exploration of profound biomedical effects of H2,and helpful for development of innovative drugs and hydrogen energy/agricultural materials. | Zhaokui Jin Penghe Zhao Wanjun Gong Wenjiang Ding Qianjun He | 2023 | Nano Research2023，16，2： | 1 |

| 8 | Enhancement of Biomass Material Characterization Images Using an Improved U-Net显示文摘For scanning electronmicroscopes with high resolution and a strong electric field,biomass materials under observation are prone to radiation damage from the electron beam.This results in blurred or non-viable images,which affect further observation of material microscopic morphology and characterization.Restoring blurred images to their original sharpness is still a challenging problem in image processing.Traditionalmethods can’t effectively separate image context dependency and texture information,affect the effect of image enhancement and deblurring,and are prone to gradient disappearance during model training,resulting in great difficulty in model training.In this paper,we propose the use of an improvedU-Net(U-shapedConvolutional Neural Network)to achieve image enhancement for biomass material characterization and restore blurred images to their original sharpness.The main work is as follows:use of depthwise separable convolution instead of standard convolution in U-Net to reduce model computation effort and parameters;embedding wavelet transform into the U-Net structure to separate image context and texture information,thereby improving image reconstruction quality;using dense multi-receptive field channel modules to extract image detail information,thereby better transmitting the image features and network gradients,and reduce the difficulty of training.The experiments show that the improved U-Net model proposed in this paper is suitable and effective for enhanced deblurring of biomass material characterization images.The PSNR(Peak Signal-to-noise Ratio)and SSIM(Structural Similarity)are enhanced as well. | Zuozheng Lian Hong Zhao Qianjun Zhang Haizhen Wang E.Erdun | 2022 | Computers, Materials & Continua2022，，7： | 0 |

| 10 | A nanoconcrete welding strategy for constructing high-performance wound dressing显示文摘Engineering biomaterials to meet specific biomedical applications raises high requirements of mechanical performances,and simultaneous strengthening and toughening of polymer are frequently necessary but very challenging in many cases.In this work,we propose a new concept of nanoconcrete welding polymer chains,where mesoporous CaCO3(mCaCO_(3))nanoconcretes which are composed of amorphous and nanocrystalline phases are developed to powerfully weld polymer chains through siphoning-induced occlusion,hydration-driven crystallization and dehydration-driven compression of nanoconcretes.The mCaCO_(3) nanoconcrete welding technology is verified to be able to remarkably augment strength,toughness and anti-fatigue performances of a model polymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate)-based porous membrane.Mechanistically,we have revealed polymer-occluded nanocrystal structure and welding-derived microstress which is much stronger than interfacial Van der Waals force,thus efficiently preventing the generation of microcracks and repairing initial microcracks by microcracks-induced hydration,crystallization and polymer welding of mCaCO_(3) nanoconcretes.Constructed porous membrane is used as wound dressing,exhibiting a special nanoplates-constructed surface topography as well as a porous structure with plentiful oriented,aligned and opened pore channels,improved hydrophilicity,water vapor permeability,anti-bacterial and cell adherence,in support of wound healing and skin structural/functional repairing.The proposed nanoconcrete-welding-polymer strategy breaks a new pathway for improving the mechanical performances of polymers. | Yingshuai Wang Yanxia Zhu Penghe Zhao Bin Wei Mingjian Fan Danyang Chen Zhaokui Jin Qianjun He | 2022 | Bioactive Materials2022，7，8： | 0 |
