Journal of Mathematical Research with Applications 2021年第4期41卷 340-348页

作者： Huiling YIN Binbin HAO xiaoyan su Jingrong CHEN School of Mathematics and Physics Lanzhou Jiaotong University School of Traffic and Transportation Lanzhou Jiaotong University

For the subset S ? V(G), if every path with k vertices in a graph G contains at least one vertex from S, we call that S is a k-path vertex cover set of the graph G. Obviously, the subset is not unique. The cardinality of the minimum k-path vertex cover set of a graph G is called the k-path vertex cover number, we denote it by ψk(G). In this paper, a lower or upper bound of ψkfor some Cartesian product graphs is presented.

SPM-IS: An auto-algorithm to acquire a mature soybean phenotype based on instance segmentation

引用

The Crop Journal 2022年第5期10卷 1412-1423页

作者： Shuai Li Zhuangzhuang Yan Yixin Guo xiaoyan su Yangyang Cao Bofeng Jiang Fei Yang Zhanguo Zhang Dawei Xin Qingshan Chen Rongsheng Zhu College of Engineering Northeast Agricultural UniversityHarbin 150030HeilongjiangChina College of Arts and Sciences Northeast Agricultural UniversityHarbin 150030HeilongjiangChina College of Agriculture Northeast Agricultural UniversityHarbin 150030HeilongjiangChina

Mature soybean phenotyping is an important process in soybean breeding;however, the manual process is time-consuming and labor-intensive. Therefore, a novel approach that is rapid, accurate and highly precise is required to obtain the phenotypic data of soybean stems, pods and seeds. In this research, we propose a mature soybean phenotype measurement algorithm called Soybean Phenotype Measure-instance Segmentation(SPM-IS). SPM-IS is based on a feature pyramid network, Principal Component Analysis(PCA) and instance segmentation. We also propose a new method that uses PCA to locate and measure the length and width of a target object via image instance segmentation. After 60,000 iterations, the maximum mean Average Precision(m AP) of the mask and box was able to reach 95.7%. The correlation coefficients R^(2) of the manual measurement and SPM-IS measurement of the pod length, pod width, stem length, complete main stem length, seed length and seed width were 0.9755, 0.9872, 0.9692, 0.9803,0.9656, and 0.9716, respectively. The correlation coefficients R^(2) of the manual counting and SPM-IS counting of pods, stems and seeds were 0.9733, 0.9872, and 0.9851, respectively. The above results show that SPM-IS is a robust measurement and counting algorithm that can reduce labor intensity, improve efficiency and speed up the soybean breeding process.

乡村旅游发展能够给当地居民带来巨大的就业机遇,社区参与能够提高乡村居民整体的社会保障水平,这为吉登斯所倡导的"第三条道路"社会保障思想提供了现实依据,也为乡村旅游实现精准扶贫效果提供了创新路径。洛阳栾川重渡沟村的社会保障在乡村旅游的影响下经历了3个阶段,1999年前未发展乡村旅游时受国家干预主义影响较大,1999—2004年乡村旅游发展体现了经济自由主义的影响,而2004年至今的实践体现了经济自由主义与国家干预主义的融合,实现了政府与市场、公平与效率、权利与责任的相对均衡,实践中已初步实现了以就业保障为基础、以养老保障及最低生活保障等为内容的乡村社会保障的全面提高。研究表明,西方背景下形成的国家干预主义及经济自由主义在中国乡村市场经济实践中有着不同的诠释及呈现方式,乡村旅游精准扶贫的关键是社区力量的觉醒及培育,其创新路径是实现"以旅游换保障",即实现乡村旅游经济功能向社会功能的转变。

A Preliminary Study on Consumer Sensory Evaluation and Acceptance of Pomelo Peel Jelly

引用

Agricultural Sciences 2023年第3期14卷 446-455页

作者： Meichu Hung Rumin Zhang Taiqin Mao Xue Gong xiaoyan su Shirong Chen College of Chemistry and Food Science Yulin Normal University Yulin China

Pomelo peel is a by-product from pomelo consumption, but it is also rich in a variety of nutrients and functional substances. In order to solve the environmental problems caused by the large amount of discarded pomelo peels every year, in this study, we recycled pomelo peels to make pomelo yellow peel jelly (PYPJ) and pomelo white peel jelly (PWPJ) according to their different characteristics in pomelo peels. And the consumer sensory evaluation (n = 50) was carried out to explore the consumers’ evaluation and acceptance for these two innovative products. The results showed that both jellies received high mean scores for all sensory attributes expect PYPJ’ taste, and the consumer acceptances of PYPJ and PWPJ were 62% and 92%, respectively. These results displayed that there is a need to further improve PYPJ, and PWPJ is a product recognized by consumers. .
