AHP-based Landscape Value Evaluation of Perennial Flower Border Application in Hefei City

An analytic hierarchy process(AHP)was employed to establish a landscape value evaluation model for 20 common species of perennial flowers in the flower border of Hefei City.With the overarching objective of determining the application value of the flower border,10 evaluation factors were identified and subsequently classified into 3 distinct grades.Grade I(L>2.5)was defined as perennial flower resources with the highest development and utilization value,including only one species of Salvia farinacea.Grade II(2.0≤L≤2.5)was defined as perennial flower varieties suitable for most areas,encompassing 9 species of plants,such asTaraxacummongolicum.Grade III(L<2.0)was defined as perennial flower varieties with low application value,encompassing 10 species of plants,such asRuellia brittoniana,but lacking the value of further popularization and application.Consequently,the proportion of their application in the flower border should be reduced.The evaluation results can serve as a theoretical foundation for the implementation of perennial flowers in urban flower borders.

Research on the Employment View of Acupuncture and Tuina Undergraduates in Minority Border Areas from Students’ Perspective

With the popularization of higher education in China,the employment situation of college students is more complex and severe.This paper adopts the questionnaire method to explore the employment view of acupuncture and tuina undergraduates of Yunnan University of Traditional Chinese Medicine.The employment concept of acupuncture and tuina undergraduates in the minority border areas has changed greatly.After graduation,97.95%of students choose to work in fields related to medicine and acupuncture,prefer positions close to home,and are attracted to high-salary companies,among other factors.Therefore,enhancing the competitive advantages of medical students by guiding their career planning,providing employment selection advice,fostering innovation and entrepreneurship,improving basic skills,and offering graduate entrance examination guidance is crucial for broadening their employment opportunities.

Border effects of the main and ratoon crops in the rice ratooning system

The border effect(BE)is widely observed in crop field experiments,and it has been extensively studied in many crops.However,only limited attention has been paid to the BE of ratoon rice.We conducted field experiments on ratoon rice in Qichun County,Hubei Province,Central China in 2018 and 2019 to compare the BE in the main and ratoon crops,and to quantify the contribution of BE in the main crop to that in the ratoon crop.The BE of two hybrid varieties was measured for the outermost,second outermost,and third outermost rows in each plot of both crops.To determine the contribution of BE between the two crops,portions of hills in the outermost and second outermost rows were uprooted during the harvest of the main crop so that the second and third outermost rows then became the outermost rows in the ratoon crop.Overall,the BE on grain yield was greater in the main crop than in the ratoon crop.In the main crop,the BE on grain yield was 98.3%in the outermost row,which was explained by the BE on panicles m^(–2),spikelets/panicle,spikelets m^(–2),and total dry weight.In the ratoon crop,the BE on grain yield was reduced to 60.9 and 27.6%with and without the contribution of the BE in the main crop,respectively.Consequently,55.1%of the BE on grain yield in the ratoon crop was contributed from the main crop.High stubble dry weight and non-structural carbohydrate(NSC)accumulation at the harvest of the main crop were responsible for the contribution of BE in the main crop to that in the ratoon crop.Our results suggest that increases in stubble dry weight and NSC accumulation at the harvest of the main crop could be important strategies for developing high-yielding cropping practices in the rice ratooning system.

A multi-UAV deployment method for border patrolling based on Stackelberg game

To strengthen border patrol measures, unmanned aerial vehicles(UAVs) are gradually used in many countries to detect illegal entries on borders. However, how to efficiently deploy limited UAVs to patrol on borders of large areas remains challenging. In this paper, we first model the problem of deploying UAVs for border patrol as a Stackelberg game. Two players are considered in this game: The border patrol agency is the leader,who optimizes the patrol path of UAVs to detect the illegal immigrant. The illegal immigrant is the follower, who selects a certain area of the border to pass through at a certain time after observing the leader’s strategy. Second, a compact linear programming problem is proposed to tackle the exponential growth of the number of leader’s strategies. Third, a method is proposed to reduce the size of the strategy space of the follower. Then, we provide some theoretic results to present the effect of parameters of the model on leader’s utilities. Experimental results demonstrate the positive effect of limited starting and ending areas of UAV’s patrolling conditions and multiple patrolling altitudes on the leader ’s utility, and show that the proposed solution outperforms two conventional patrol strategies and has strong robustness.

Progress of Central Bank Digital Currency in Cross-border Payments and the Application Prospect in the Oil and Gas Field

The rapid development of the digital economy and profound changes in currency functions have driven the emergence of a large number of digital currencies.In order to improve the competitiveness and efficiency of payment systems,governments all over the world have accelerated the research and development of central bank digital currency(CBDC).After years of preparation and research and development,Digital renminbi has also entered the pilot application stage.Given the many shortcomings of the current cross-border payment system,CBDC cross-border payment has become an important development direction.At present,some central banks are collaborating on CBDC cross-border payment research and initiating experimental plans to explore CBDC cross-border payment arrangements.With the expansion of the acceptance range of Digital renminbi and the improvement of the international use level of CNY,oil and gas enterprises will have broad prospects in the cross-border payment field in the future.This paper suggests that oil and gas enterprises,in accordance with the principle of"from easy to difficult,step by step",give priority to the introduction of Digital renminbi from regions and fields where RMB or local currency settlement has been achieved,and combine Digital renminbi with imported oil and gas to explore the use of Digital renminbi in cross-border payment.

跨境知识产权侵权纠纷的域外法律适用

各国在处理跨境知识产权侵权纠纷的域外法律适用问题时主要采取两种模式,即单向域外适用模式与双向域外适用模式。前者更多地是将知识产权视为一种政策性的特权,在处理域外侵权行为时往往不会发生外国的知识产权法被本国法院所适用的情况,但会出现本国知识产权法适用于发生在域外行为的情形;后者更多地是将知识产权视为一种民事权利,对于发生在域外的行为,本国法院既可能适用本国知识产权法律,也可能适用外国知识产权法律,是否发生外国法律的适用取决于一国立法对较为中立的连接点的界定。我国在立法上采取了以“被请求保护地”为连接点的双向域外适用模式,但是在司法实践中往往并不进行法律选择而是径行适用中国知识产权法律。这将导致在司法上采取了将中国知识产权法律适用于域外行为的单向域外适用模式。我国应在跨境知识产权侵权纠纷的域外法律适用问题上回归双向域外适用模式,并在具体纠纷裁判中丰富和明确“被请求保护地”的含义,同时设置“无所不在”侵权行为的特殊法律适用规则,限制当事人共同选择适用法的范围以及确定公共秩序在准据法选择中的适用,以实现维护本国利益的目的。

多情景模拟下的跨境铁路运输时效研究——以中老铁路为例

跨境铁路运输是中国与周边国家陆路联通的重要环节。跨境铁路运输时效既受线路畅通情况、基础设施技术等级等“硬联通”因素的制约,也受到海关条例、口岸畅通水平等“软联通”因素的影响。因此,跨境铁路运输时效研究应充分考虑不同情景,以期更科学地模拟运输时长的变化机理。本文以中老铁路(中国昆明−老挝万象,简称中老铁路)为例,在梳理中老铁路沿线地区社会经济概况及基础设施发展水平的基础上,考虑不同运营速度、通关时间、铁轨换装、多式联运等因素,构建了长途跨境运输时间的计算模型,采用多情景模拟方法,解析了中老铁路运的优势距离及客货运时效变化。研究表明:①中老铁路有助于沿线跨境运输时间显著减少。相比公路运输,客货运时间优势均超过20%;②通关时间是影响跨境铁路运输的关键要素之一,占运输总时长的20%~60%;③铁海联运是中老铁路运输进一步提升运输效率的途径,能有效缩短老挝至日本的总运输时间。
