A new hybrid artificial bee colony algorithm for global optimization
Xiangyu Kong,Sanyang Liu,Zhen Wang
International Journal of Computer Science Issues , 2013,
Abstract: To further improve the performance of artificial bee colony algorithm (ABC), a new hybrid ABC (HABC) for global optimization is proposed via exploring six initialization methods. Furthermore, to balance the exploration and exploitation abilities, a new search mechanism is also developed. The algorithms are applied to 27 benchmark functions with various dimensions to verify its performance. Numerical results demonstrate that the proposed algorithms outperforms the ABC in global optimization problems, especially the HABC algorithm with random initialization and HABCO algorithm with orthogonal initialization.
On the Present Situation and Suggestions of Institutional Education in Universities  [PDF]
Xiangyu Leng
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.510021
Abstract:
University institutions are among the resources of civic education; institutional education is to develop all-round people with good rules and regulations; university institutions haven’t achieved their educational effects in the civic education; this research explores the effect of the institution in university, and the reasons for the poor effect of institution education; we have to strengthen the institutional construction of universities to achieve the goal of civic education through the following routes: One is to re-examine the virtue of university institution and to examine whether the university institution conforms to the rule of law; the other one is to ensure strict implementation of university institution. Only in this way, can university institutional education enhance the civic consciousness of college students.
The Influence of Shadow Education on Cognitive Ability and Non-Cognitive Ability  [PDF]
Xiangyu Zhao
Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.103063
Abstract: Utilizing a nationally representative data set from China Education Panel Survey (CEPS), this study examines the effects of family factors and extra-curricular tutoring on Chinese students’ cognitive ability and non-cognitive ability. Based on the method of Ordinary Least Square (OLS) and Propensity Score Matching (PSM), we find that family socioeconomic status (SES) has a significant positive impact on both cognitive and non-cognitive ability. At the same time, family relationships significantly boost students’ non-cognitive ability. As for shadow education, we concluded that academic tutoring has a positive effect on students’ cognitive ability, but it has no significant positive effect on non-cognitive ability, while the positive effect of interest tutoring on non-cognitive ability is greater than the negative influence effect on cognitive ability.
A Literature Review of Directors’ Supervising Managers: Based on the Comparison of Equity Incentives and Monetary Salary Incentives  [PDF]
Xiangyu Li
Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.104081
Abstract: This paper analyzes the relevant literature on directors’ supervision of managers in terms of monetary compensation incentives and equity incentives. By comparing the advantages and disadvantages of monetary compensation incentives and equity incentives in the supervision of managers by directors, this paper believes that equity incentives can more clearly discover the supervisory supervision of directors. At the same time, this paper believes that in the case of equity incentives, joint incentives for directors and managers can promote the supervision of directors. The analysis conclusions of this paper have guiding significance in the actual corporate governance process.
Design and immunogenicity assessment of HIV-1 virus-like particles as a candidate vaccine
XiZhen Zhang,XiaoDan Wang,DongHai Zhao,XiangYu Meng,XingHong Zhao,XiangHui Yu,Wei Kong
Science China Life Sciences , 2011, DOI: 10.1007/s11427-011-4244-0
Abstract: The rapid growth of the global HIV/AIDS epidemic makes it a high priority to develop an effective vaccine. Since a live attenuated or inactivated HIV vaccine is not likely to be approved for clinical application due to safety concerns, HIV virus like particles (VLPs) offer an attractive alternative because they are considered safer since they lack viral genome. We got a stable eukaryotic cell line by G418 resistance selection, engineered to express the HIV-1 structure protein Gag and Env efficiently and stably. We confirmed the presence of Gag and Env proteins in the cell culture supernatant and that they could self-assemble into VLPs. These VLPs were found to be able to elicit specific humoral and cellular immune response after immunization without any adjuvant.
A lasing mechanism based on absorption boundary of gain materials
Jinwei Shi,Shujing Chen,Wenjun Fan,Xiangyu Kong,Dahe Liu,Lily Zu
Physics , 2013,
Abstract: A new kind of mechanism of lasing is investigated experimentally. It is quite different from the traditional laser with cavity and the random laser with random scattering. In this mechanism, the intensity-dependent refractive index effect and thermal lensing effects of the pump beam induce a large gradient of the refractive index in the gain material, which forms a passive equivalent boundary that provides the feedback in the lasing system. A real lasing system, a liquid disk laser, is performed, it achieves 2-D omnidirectional radiation with a high efficiency of 28%, its radiation spectral property can be explained by resonant Raman scattering.
On Relationship between Pediatric Shi Ji and Fever  [PDF]
Xiangyu Hu, Lina Hu
Open Journal of Pediatrics (OJPed) , 2015, DOI: 10.4236/ojped.2015.53036
Abstract: Based on the clinical effect of the treatment on 546 Pediatric Shi Ji fever cases, the thesis tries to explore the effectiveness of Traditional Chinese Medicine(TCM) treatment on Pediatric Shi Ji and the relationship between Pediatric Shi Ji and fever. The methodology applied is a retrospective analysis on the clinical curative effect of TCM treatment on Shi Ji fever cases in our hospital from January 2008 to December 2012. And the results show that a total effective rate of 96.3% could be guaranteed through either oral Chinese Medicinal Herbs, Chinese Medicine Enema, Massage Therapy, or navel administration with TCM. The thesis holds that Pediatric Shi Ji may cause fever, which could be cured simply by applying TCM treatment (promoting digestion to eliminate stagnation) with less or no use of antibiotics.
Impact on Public Cultural Spending: The Perspective of Institutional Change in Government Cultural Functions  [PDF]
Bin Tu, Xiangyu Tao
Open Journal of Political Science (OJPS) , 2017, DOI: 10.4236/ojps.2017.73027
Abstract: This article explores the government cultural function factors that affect government spending on public culture services in the main point-institutional hinge by using historical data in China. The results yield main finding which is the institutional change of government cultural function would affect the scale, structure and efficiency of public cultural spending. At present, the insufficiency of values guide in government cultural functions leads to the low efficiency of public cultural expenditure, thus, institutional arrangement of government’s cultural function should pay more attention to the guidance of positive values to improve the efficiency of public finance resources in the cultural field.
Using Augmented Reality to Plan Virtual Construction Worksite
Xiangyu Wang
International Journal of Advanced Robotic Systems , 2008,
Abstract: Current construction worksite layout planning heavily relies on 2D paper media where the worksite planners sketch the future layout adjacent to their real environment. This traditional approach turns out to be ineffective and prone to error because only experienced and well-trained planners are able to generate the effective layout design with paper sketch. Augmented Reality (AR), as a new user interface technology, introduces a completely new perspective for construction worksite planning. This paper disucsses the related AR work and issues in construction and describes the concept and prototype of an AR-based construction planning tool, AR Planner with virtual elements sets and tangible interface. The focus of the paper is to identify and integrate worksite planning rules into the AR planner with the purpose of intelligently preventing potential planning errors and process inefficiency, thus maximizing the overall productivity. Future work includes refining and verifying AR Planner in realistic projects.
