An Efficient Adaptive Iteratively Reweighted l1 Algorithm for Elastic lq Regularization  [PDF]
Yong Zhang, Wanzhou Ye
Advances in Pure Mathematics (APM) , 2016, DOI: 10.4236/apm.2016.67036
Abstract: In this paper, we propose an efficient adaptive iteratively reweighted l1 algorithm (A-IRL1 algorithm) for solving the elastic lq regularization problem. We prove that the sequence generated by the A-IRL1 algorithm is convergent for any rational \"\" and the limit is a critical point of the elastic lq regularization problem. Under certain conditions, we present an error bound for the limit point of convergent sequence.
A Literature Review of Self-Sacrificial Leadership  [PDF]
Hanbing Zhang, Maolin Ye
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.79121
Abstract: In the ever-competitive global business environment, companies may fail to adapt to the environment due to crisis. In this situation, companies call for self-sacrificing leaders to help companies get out of the woods. Self-sacrificing leadership is a spirit or behavior manifesting the leader’s willingness to take on various kinds of risks and losses for the sake of the benefits of the whole organization and the subordinates. We explored the dimension and measurement methods, In order to clarify the nature of self-sacrificing leadership and the theoretical boundary with other leadership, we make a comparison of self-sacrificing leadership and other leadership. Future research can strengthen the study on the concept, measurement methods of self-sacrificing leadership.
The Properties and Fast Algorithm of Quaternion Linear Canonical Transform  [PDF]
Ye Zhang, Guanlei Xu
Journal of Signal and Information Processing (JSIP) , 2018, DOI: 10.4236/jsip.2018.93012
Abstract: The quaternion linear canonical transform (QLCT) is defined in this paper, with proofs given for its reversibility property, its linear property, its odd-even invariant property and additivity property. Meanwhile, the quaternion convolution (QCV), quaternion correlation (QCR) and product theorem of LCT are deduced. Their physical interpretation is given as classical convolution, correlation and product theorem. Moreover, the fast algorithm of QLCT (FQLCT) is obtained, whose calculation complexity for different signals is similar to FFT. In addition, the paper presents the relationship between the convolution and correlation in LCT domains, and the convolution and correlation can be calculated via product theorem in Fourier transform domain using FFT.
Economy, Environment and Government: Study on the Path of Supply-Side Reform Forced by the Fog-Haze  [PDF]
Jiaorui Li, Ye Zhang, Shuang Zhang
Journal of Applied Mathematics and Physics (JAMP) , 2019, DOI: 10.4236/jamp.2019.72023
Abstract: Unbalanced development in term as industrial structure and the efficiency use of energy have aggravated environmental pollution to different degrees resulting in the increase of range, time and degree of fog-haze. This, in turn, forced the government to carry out supply-side reforms, to improve energy efficiency and optimize the industrial structure to weaken the environmental pollution. To tackle these problems, this work provides an index system for the issues related to fog-haze, uses a non-linear ST-SVAR model to reflect the effects of industrial structure and energy use efficiency on fog-haze. Results indicated that: First, current industrial structure and energy use efficiency have greater impact on the comprehensive equation of fog-haze risk than itself. With the passage of time, this influence is still gradually expanding. Second, the equations of industrial structure and energy use efficiency are strongly influenced by themselves, and other variables as the current period have less impact on them. Finally, the non-linear or asymmetric relationship is shown among industrial structure, energy use efficiency, and the fog-haze comprehensive risk equation.
The Product Category Effects on Capital Structure: Evidence from the SMEs of British Manufacturing Industry
Ye Zhang
International Journal of Business and Management , 2010, DOI: 10.5539/ijbm.v5n8p86
Abstract: This paper investigates into the determinants of capital structure for the small and medium sized enterprises (SMEs) in British manufacturing industry and the effects of product category on the determinants of capital structure. 220 SMEs from British manufacturing industry are selected for testing the six hypothesized relationships regarding the determinants of capital structure. Results suggest that profitability, tangibility and size are positively and growth is negatively related to the debt/equity ratio, and age is in inconsistent relationship with the debt/equity ratio of British manufacturing SMEs. Product category does exert effects through the determinants of capital structure and profitability is the most important determinant through which product category imposing effects on capital structure. The interactive effects of the determinants of capital structure are also the important discovery of this paper.

Yongmei Xu, Fan Zhang, Xiaowen Ye
Technology and Investment (TI) , 2013, DOI: 10.4236/ti.2013.42009
Abstract:

Based on the literature review which concludes the Lean Six Sigma management theory, Information Technology Infrastructure Library (ITIL) and the key success factors of Information Technology service management (ITSM), this paper analyzes the present situation of information system in G bank and also the challenge it is facing. Furthermore, this paper puts forward a process optimization scheme for the production changes of G bank’s ITSM with the Lean Six Sigma management theory. What’s more, the paper dissects the production changes of G bank’s ITSM by means of DMAIC method in order to achieve these four goals: Firstly, optimizing the process and improving the internal work efficiency also. Secondly, reducing the variation and the error rate and also improving the system availability. Thirdly, strengthen the business interaction in order that the IT value could be reflected preferably. The last but not least, cutting the overtime is to improve employee satisfaction. But improving the ITSM of the banking industry is our ultimate aim.

The Customer Satisfaction Research of 7-ELEVEn Stores in Hong Kong  [PDF]
Yongmei Xu, Xiaowen Ye, Fan Zhang
Journal of Service Science and Management (JSSM) , 2013, DOI: 10.4236/jssm.2013.61006
Abstract:

Using the 7-ELEVEn stores in Hong Kong as an example, this paper has studied customer satisfaction from the point of view of the enterprise. This paper has established a retail enterprise customer satisfaction model based on CCSI models. The secondary indexes of this customer satisfaction model include the following content: enterprise/brand image, quality expectations (shopping environment of convenience stores), quality perception (staff’s service quality), value perception, customer satisfaction, complaints and loyalty of customers and there are also 18 indexes in third class indicators. With the principal component analysis, it can be found that three important factors were value and overall satisfaction, employee service quality, shopping environment and brand image, besides three satisfaction factors were shopping environment, the staff’s service quality and perceived value. The aim of this paper is to provide reference for the key of enterprise’s future work and also for the optimal distribution of resources.

Financial Development, Urbanization, and Urban-Rural Income Disparity: Evidence Based on Chinese Provincial Data  [PDF]
Zhiqiang Ye, Lixia Qian, Zhang Na
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.91003
Abstract: China’s economic development has maintained a rapid growth trend since 1978, but the problem of imbalanced income distribution between urban and rural residents also has been increasingly aggravated. This paper discusses the relationship between financial development and urban-rural income disparity and examines the impact of urbanization on the relationship between financial development and urban-rural income disparity. Then this paper selects the provincial panel data of 28 provinces in China from 1978 to 2014, using GMM dynamic model and fixed effect panel model, respectively, to do the empirical test. The results show that: 1) the imbalance of urban and rural financial resources is exacerbated by the financial threshold effect, leading to the fact that the financial development-measured by scale, efficiency and structure, respectively, expand the urban-rural income gap. 2) The developing urbanization will widen the urban-rural income gap. However, as the urbanization and mainly the urbanization of land is rapid in China, the expansion effect of the increasing financial development level on the income gap between urban and rural residents in China will be weakened with the acceleration of urbanization based on the financial threshold effect. It provides empirical support for the financial reform and for the assumption that urbanization development reduces the income gap between urban and rural areas.

Lingxiao Ye, Xiaoming Sun, Yuguang Zhang, Ying Zhang
Journal of Biomedical Science and Engineering (JBiSE) , 2019, DOI: 10.4236/jbise.2019.122006
Abstract: Wound healing requires abundant nutrition and blood supply, thus angiogenesis is a vital stage in this process. Angiogenesis involves diverse kinds of immune cells, growth factors, cytokines and inhibitors. ADSCs, especially ADSCs cultured in hypoxic condition, are reported to be able to facilitate angiogenesis and promote wound healing process. Significant efforts have been made on the development of ADSCs-based therapies with wound-healing applications. Here the results showed that expression of Angiopoietin-2 (ANGPT2) in ADSCs was up-regulated in the hypoxic condition.
