| 1 | Spatial patterns and driving forces of land use change in China during the early 21st century显示文摘Land use and land cover change as the core of coupled human-environment systems has become a potential field of land change science (LCS) in the study of global environmental change. Based on remotely sensed data of land use change with a spatial resolution of 1 km × 1 km on national scale among every 5 years, this paper designed a new dynamic regionalization according to the comprehensive characteristics of land use change including regional differentiation, physical, economic, and macro-policy factors as well. Spatial pattern of land use change and its driving forces were investigated in China in the early 21st century. To sum up, land use change pattern of this period was characterized by rapid changes in the whole country. Over the agricultural zones, e.g., Huang-Huai-Hai Plain, the southeast coastal areas and Sichuan Basin, a great proportion of fine arable land were engrossed owing to considerable expansion of the built-up and residential areas, resulting in decrease of paddy land area in southern China. The development of oasis agriculture in Northwest China and the reclamation in Northeast China led to a slight increase in arable land area in northern China. Due to the 'Grain for Green' policy, forest area was significantly increased in the middle and western developing regions, where the vegetation coverage was substantially enlarged, likewise. This paper argued the main driving forces as the implementation of the strategy on land use and regional development, such as policies of 'Western Development', 'Revitalization of Northeast', coupled with rapidly economic development during this period. | LIU Jiyuan ZHANG Zengxiang XU Xinliang KUANG Wenhui ZHOU Wancun ZHANG Shuwen LI Rendong YAN Changzhen YU Dongsheng WU Shixin JIANG Nan | 2010 | Journal of Geographical Sciences2010，20，4： | 154 |

| 3 | Role of transition metal oxides in g-C_(3)N_(4)-based heterojunctions for photocatalysis and supercapacitors显示文摘g-C_(3)N_(4) emerges as a star 2D photocatalyst due to its unique layered structure,suitable band structure and low cost.However,its photocatalytic application is limited by the fast charge recombination and low photoabsorption.Rationally designing g-C_(3)N_(4)-based heterojunction is promising for improving photocatalytic activity.Besides,g-C_(3)N_(4) exhibits great potentials in electrochemical energy storage.In view of the excellent performance of typical transition metal oxides(TMOs)in photocatalysis and energy storage,this review summarized the advances of TMOs/g-C_(3)N_(4) heterojunctions in the above two areas.Firstly,we introduce several typical TMOs based on their crystal structures and band structures.Then,we summarize different kinds of TMOs/g-C_(3)N_(4) heterojunctions,including type Ⅰ/Ⅱ heterojunction,Z-scheme,p-n junction and Schottky junction,with diverse photocatalytic applications(pollutant degradation,water splitting,CO_(2) reduction and N_(2) fixation)and supercapacitive energy storage.Finally,some promising strategies for improving the performance of TMOs/g-C_(3)N_(4) were proposed.Particularly,the exploration of photocatalysis-assisted supercapacitors was discussed. | Liqi Bai Hongwei Huang Shixin Yu Deyang Zhang Haitao Huang Yihe Zhang | 2022 | Journal of Energy Chemistry2022，31，1： | 5 |
| 4 | Differentiation of mesenchymal stem cells into neuronal cells on fetal bovine acellular dermal matrix as a tissue engineered nerve scaffold显示文摘The purpose of this study was to assess fetal bovine acellular dermal matrix as a scaffold for supporting the differentiation of bone marrow mesenchymal stem cells into neural cells following induction with neural differentiation medium.We performed long-term,continuous observation of cell morphology,growth,differentiation,and neuronal development using several microscopy techniques in conjunction with immunohistochemistry.We examined specific neuronal proteins and Nissl bodies involved in the differentiation process in order to determine the neuronal differentiation of bone marrow mesenchymal stem cells.The results show that bone marrow mesenchymal stem cells that differentiate on fetal bovine acellular dermal matrix display neuronal morphology with unipolar and bi/multipolar neurite elongations that express neuronal-specific proteins,including βIII tubulin.The bone marrow mesenchymal stem cells grown on fetal bovine acellular dermal matrix and induced for long periods of time with neural differentiation medium differentiated into a multilayered neural network-like structure with long nerve fibers that was composed of several parallel microfibers and neuronal cells,forming a complete neural circuit with dendrite-dendrite to axon-dendrite to dendrite-axon synapses.In addition,growth cones with filopodia were observed using scanning electron microscopy.Paraffin sectioning showed differentiated bone marrow mesenchymal stem cells with the typical features of neuronal phenotype,such as a large,round nucleus and a cytoplasm full of Nissl bodies.The data suggest that the biological scaffold fetal bovine acellular dermal matrix is capable of supporting human bone marrow mesenchymal stem cell differentiation into functional neurons and the subsequent formation of tissue engineered nerve. | Yuping Feng Jiao Wang Shixin Ling Zhuo Li Mingsheng Li Qiongyi Li Zongren Ma Sijiu Yu | 2014 | Neural Regeneration Research2014，9，22： | 4 |
| 5 | Automatic segmentation of foveal avascular zone based on adaptive watershed algorithm in retinal optical coherence tomography angiography images显示文摘The size and shape of the foveal avascular zone(FAZ)have a strong positive correlation with several vision-threatening ret inovascular diseases.The identification,segmentation and analysis of FAZ are of great significance to clinical diagnosis and treatment.We presented an adaptive watershed algorithm to automatically extract F AZ from retinal optical coherence tomography angiography(OCTA)images.For the traditional watershed algorithm,'over-segmentation'is the most common problem.FAZ is often incorrectly divided into multiple regions by redundant'dams'.This paper analyzed the relationship between the'dams'length and the maximum inscribed circle radius of FAZ,and proposed an adaptive watershed algorithm to solve the problem of'over-segmentation'.Here,132 healthy retinal images and 50 diabetic retinopathy(DR)images were used to verify the accuracy and stability of the algorithm.Three ophthal-mologists were invited to make quan titative and qualitative evaluations on the segmentation results of this algorithm.The quantitative evaluation results show that the correlation coffi-cients between the automatic and manual segmentation results are 0.945(in healthy subjects)and 0.927(in DR patients),respectively.For qualitative evaluation,the percentages of'perfect segmentation'(score of 3)and'good segmentation'(score of 2)are 99.4%(in healthy subjects)and 98.7%(in DR patients),respectively.This work promotes the application of watershed algorithm in FAZ segmentation,making it a useful tool for analyzing and diagnosing eye diseases. | Jian Liu Shixin Yan Nan Lu Dongni Yang Chunhui Fan Hongyu Lv Shuanglian Wang in Zhu Yuqian Zhao Yi Wang Zhenhe Ma Yao Yu | 2022 | Journal of Innovative Optical Health Sciences2022，15，1： | 3 |

| 11 | Target Detection Algorithm in Foggy Scenes Based on Dual Subnets显示文摘Under the influence of air humidity,dust,aerosols,etc.,in real scenes,haze presents an uneven state.In this way,the image quality and contrast will decrease.In this case,It is difficult to detect the target in the image by the universal detection network.Thus,a dual subnet based on multi-task collaborative training(DSMCT)is proposed in this paper.Firstly,in the training phase,the Gated Context Aggregation Network(GCANet)is used as the supervisory network of YOLOX to promote the extraction of clean information in foggy scenes.In the test phase,only the YOLOX branch needs to be activated to ensure the detection speed of the model.Secondly,the deformable convolution module is used to improve GCANet to enhance the model’s ability to capture details of non-homogeneous fog.Finally,the Coordinate Attention mechanism is introduced into the Vision Transformer and the backbone network of YOLOX is redesigned.In this way,the feature extraction ability of the network for deep-level information can be enhanced.The experimental results on artificial fog data set FOG_VOC and real fog data set RTTS show that the map value of DSMCT reached 86.56%and 62.39%,respectively,which was 2.27%and 4.41%higher than the current most advanced detection model.The DSMCT network has high practicality and effectiveness for target detection in real foggy scenes. | Yuecheng Yu Liming Cai Anqi Ning Jinlong Shi Xudong Chen Shixin Huang | 2024 | Computers, Materials & Continua2024，78，2： | 0 |
| 12 | On the Gray Images of Some Constacyclic Codes over Fp + uFp + u^2Fp显示文摘Constacyclic codes are an important class of linear codes in coding theory.Many optimal linear codes are directly derived from constacyclic codes.In this paper,a new Gray map between codes over F_p+uF_p+u^2F_p and codes over Fp is defined,where p is an odd prime.By means of this map,it is shown that the Gray image of a linear(1+u+u^2)-constacyclic code over F_p+uF_p+u^2F_p of length n is a repeated-root cyclic code over F_p of length pn.Furthermore,some examples of optimal linear cyclic codes over F_3 from(1+u+u^2)-constacyclic codes over F_3+uF_3+u^2F_3 are given. | YU Haifeng ZHU Shixin KAI Xiaoshan | 2016 | Journal of Systems Science & Complexity2016，29，3： | 0 |
