A high-density genetic map is a prerequisite for marker-assisted selection of crop species. Here, we developed a high-density genetic map of Vitis using 92 F1 progeny derived from the cross between two wine grape cultivars, ‘Shuanghong’ and ‘Italian Riesling’. Whole genome resequencing (WGS) technology was used to generate SNP markers for the map. The map consisted of 1351 recombination bin markers (210,873 SNPs), distributed on 19 linkage groups (LGs), with an average distance of 0.65 cM between adjacent bin markers and a map distance of 860.46 cM. The high levels of uniform coverage and collinearity between the 19 LGs and the grape reference genome indicated that the map is of high quality and can serve as a powerful platform for evaluating grapevines and deciphering the genetic mechanism of important economic and agronomic traits. Our findings will facilitate the process of mapping quantitative trait loci (QTL) that control important horticultural and economic traits of grape.

Multiple Circles Detection in Complex Scenes

Chu Guangli,Wang Yanjie,Sun Honghai,Fan Bo,Wen Zhuoman 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.1

To solve the problem that the conventional circle detection algorithm has low processing speed and poor identification accuracy in presence of overlap of objects, a novel multiple circles detection algorithm is proposed. Firstly, the consecutive edges with single pixel are obtained through an edge tracking method. Moreover, the edges of overlaid objects are extracted from the cross section according to the linear projection method. Secondly, a large number of non-circular edges are excluded by utilizing a coarse detection that decides whether four points on an edge are on the same circle or not. Lastly, the circles are recognized by the fine detection according to the geometrical feature which two subarcs belonging to one circle have the same center and radius. The experimental results demonstrate that the algorithm is superior in speed, precision and accuracy, comparing to the conventional ones, such as Hough transform circle detection and randomized circle detection. Furthermore, it can solve the issues from overlap of objects and accurately identify the multiple circular objects in the complex scenes as well. The algorithm is concise, fast and robust.

Failure Mechanism of Giant-Thick Strata Characterized by Weak Cementation Based on Superimposed Similar Material Simulation

Guojian Zhang,Guangli Guo,Yaqiang Gong,Anliang Xiao,Tonglong Zhao,Huaizhan Li 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.8

Deep mining puts forward higher requirements for the existing similar material simulation methods and monitoring techniques. The idea of superimposed similar material simulation is proposed to study the motion mechanism of high-stand and giant-thickness weak cementation sandstone, and its motion law is observed by the new method of single-binocular close-range photogrammetry, and verified by numerical simulation method. The results show that: first, the measurement accuracy of single close-range photogrammetry reaches the sub-millimeter level, with its medium errors of 0.18 mm and 0.17 mm in left and right camera respectively. Second, during the damage process of the thick weak cementation strata, the secondary equilibrium structure and regenerative equilibrium structure are formed, causing the destruction mode to go through four stages of ‘arch shell-beam-arch shell-step’ type damage. After the ‘arch shell-beam’ type destruction of the thick Zhidan group sandstone, its movement process disappears in the temporal correlation and shows the characteristics of the surface subsiding immediately after mining. Last, the surface subsidence develops with the saltation, and there is a quadratic polynomial function between the surface subsidence coefficient and the width-depth ratio. The above results can be used to guide the safety mining under the giant-thick weak cementation overburden.

Xiaopeng Liu,Guangli Guo,Huaizhan Li 대한토목학회 2019 KSCE JOURNAL OF CIVIL ENGINEERING Vol.23 No.11

Coal mining can lead to various forms of surface deformation, the damage caused by curvature deformation is the most extensive, which has become the key to restricting the development and utilization of coal resources under villages. Therefore, it is very important to master the deformation and destruction mechanism of buildings under surface curvature deformation for the rational exploitation of coal resources under villages. In this paper, the deformation and damage of buildings caused by curvature deformation are studied with theoretical analysis and numerical simulation, aiming at the shallow foundation building in rural China, and the following objectives are achieved: 1) Based on the theory of elastic foundation beam, the longitudinal and transverse walls are considered as a whole and analyzed, and a mathematical model of the cooperative deformation in building walls under surface curvature deformation is established. 2) The failure mechanism of masonry buildings is analyzed, including the distribution of internal stress and the form of wall cracks. 3) The influence of various factors on the internal stress changes of buildings is discussed. 4) The results of numerical simulation of wall stress distribution are similar to theoretical analysis, and the influence of doors and windows on the additional stress distribution is analyzed emphatically. This study can provide important guidance for the optimization of coal mining design under villages and the protection of village buildings.

Yuming Dong,Guangli Wang,Pingping Jiang,Aimin Zhang,Lin Yue,Xiaoming Zhang 대한화학회 2010 Bulletin of the Korean Chemical Society Vol.31 No.10

The degradation efficiencies of phenol in aqueous solution were studied by semi-continuous experiments in the processes of ozone alone, ozone/bulky Co3O4 and ozone/Co3O4 nanoparticles. Catalyst samples (bulky Co3O4 and Co3O4 nanoparticles)were characterized by X-ray diffraction and transmission electron microscopy. The Brunauer-Emmett-Teller surface area, pHpzc and the density of surface hydroxyl groups of the two catalyst samples were also measured. The catalytic activity of Co3O4 nanoparticles was investigated for the removal of phenol in aqueous solutions under different reaction temperatures. Tert-butyl alcohol had little effect on the catalytic ozonation processes. Based on these results,the possible catalytic ozonation mechanism of phenol by Co3O4 nanoparticles was proposed as a reaction process between ozone molecules and pollutants.

Tao Wei,Guangli Guo,Huaizhan Li,Lei Wang,Xiangsheng Yang,Yuezong Wang 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.5

Accurately detecting the location of the goafs is an effective method for coordinating underground mining and surface engineering construction and realizing illegal mining supervision. Aiming at the problems of the existing solution methods of goaf spatial characteristic parameters, a spatial location identification method of coal underground goaf with fusing minimal unit probability integration method and optimized quantum annealing is proposed. Meanwhile, to study the characteristics and stability of the proposed model, the advantages and disadvantages of space movement vector data, the robust ability of the method, and the application of multi-source data are discussed in the Discussions. Finally, the achievements of this paper apply to 1414 (1) working face of Gubei Coal Mine in Huainan. The results show the model can accurately identify the location and boundary of the goaf. The research achievements have important theoretical and practical significance for solving problems of land resource reuse in mining areas lacking geological mining data, coal mine safety production, and the supervision of illegal mining.

The Stability Analysis Method of Leveling Datum Points in Mining Areas of Western China Based on SBAS-InSAR Technology

Qiu Du,Guangli Guo,Huaizhan Li,Yaqiang Gong,Tao Wei 대한토목학회 2022 KSCE JOURNAL OF CIVIL ENGINEERING Vol.26 No.12

The Stability analysis of datum points is a fundamental procedure to verify the monitoring results of leveling settlement. Traditional methods tend to be the employment of repeated monitoring or the increase in measurement points under the same monitoring technique, which are costly and complicated in data processing, making them difficult to be applied in common ground subsidence monitoring scenarios. In view of this, inspired by the idea of external validation, this paper proposes an evaluation method of the stability of datum points in leveling Observation based on Small Baseline Subset InSAR (SBAS-InSAR) technology. Firstly, the paper indicates that differences of subsidence measured by SBAS-InSAR and ground leveling of the same location respectively within close proximity are primarily composed of error caused by unconformity of the position, observation time and measurement method error as well as the displacement of datum points. Based on that, the formulas of calculating errors of unconformity of observation time and the displacement of datum points are derived separately. Afterwards, taking the monitoring of surface subsidence caused by the mining of two working faces in Yingpanhao Coal Mine located in northern Ordos Basin, as practical applications, the feasibility of the method proposed in the paper is verified. And the scope of application of the proposed method is also suggested. This study provides an efficient and economical solution for evaluating the stability of datum points in leveling settlement monitoring, promoting the joint combination of SBAS-InSAR technology and traditional leveling when applied to surface subsidence monitoring.

Synergistic Effect of Copper and Cobalt in Cu-Co-O Composite Nanocatalyst for Catalytic Ozonation

Yuming Dong,Lina Wu,Guangli Wang,Hui Zhao,Pingping Jiang,Cuiyun Feng 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.11

A novel Cu-Co-O composite nanocatalyst was designed and prepared for the ozonation of phenol. A synergistic effect of copper and cobalt was observed over the Cu-Co-O composite nanocatalyst, which showed higher activity than either copper or cobalt oxide alone. In addition, the Cu-Co-O composite revealed good activity in a wide initial pH range (4.11-8.05) of water. The fine dispersion of cobalt on the surface of copper oxide boosted the interaction between catalyst and ozone, and the surface Lewis acid sites on the Cu-Co-O composite were determined as the active sites. The Raman spectroscopy also proved that the Cu-Co-O composite was quite sensitive to the ozone. The trivalent cobalt in the Cu-Co-O composite was proposed as the valid state.
