Chiral phase transition and meson spectrum in improved soft-wall AdS/QCD

We investigate in detail the chiral thermal transition of QCD in an improved soft-wall AdS/QCD model with a simply modified 5D conformal mass of the bulk scalar field. We also present a calculation in this model for the light meson spectra and other low-energy characteristic quantities including the pion form factor, the pi-rho coupling constant and the decay constants of pi, rho, a_1, which are shown to result in a good agreement with experimental data except for the pion decay constant. The thermal behavior of chiral condensate is studied. It is found that such a simply improved soft-wall model incorporates the crossover behavior of chiral thermal transition indicated by lattice simulations. The expected chiral transition temperature can be obtained

What Promotes Customers’ Trust in The Mobile Payment Platform: An Empirical Study Of Alipay In China

Trust was recognized as a significant factor in facilitating customers’ continuance intention of mobile payment. Drawing upon innovation diffusion and trust theory, this study developed a research model to examine five critical antecedents that promote customers’ trust in the mobile payment platform. An empirical survey was conducted in China and structural equation modelling method was used to examine the research model. 394 questionnaires were collected from users of Alipay, which is one of the largest mobile payment platforms in China. The analysis results suggest that security is the most significant antecedent of trust, followed by platform reputation. In addition, mobility and customization characteristics are also beneficial to promote customers’ trust in the mobile payment platform. While compatibility is directly associated with customers’ continuance intention without mediated by trust. Conclusions and future research directions are discussed in the final section

Trust Building in the Mobile Payment Platform:

This study investigates gender differences issue regarding the effect of platform characteristics on trust and continuance intention in the context of mobile payment. Drawing upon innovation diffusion and trust theory, a research model is developed to examine four significant antecedents of trust for male and female users. An empirical survey was conducted and 740 valid questionnaires were collected from users of Alipay and Wechat pay, which are recognized as two leading mobile payment platforms in China. Structural equation modelling analysis results suggest that security is the most significant antecedent of customers’ trust, followed by platform reputation, mobility and customization. Specifically, a multi-group analysis results indicate that mobility and reputation have more significant influence on trust for males, while customization and security are more important in promoting trust for females. Theoretical and practical implications are discussed in the final section

2,5-Bis[2-(4-methyl­phen­yl)ethyn­yl]benzyl methacrylate

In the title bis-tolane derivative, C29H24O2, the central benzene ring forms dihedral angles of 29.12 (9) and 26.46 (9)° with the other two benzene rings. The dihedral angle between two terminal benzene rings is 55.58 (8)°

Uncovering the Trust Transfer Mechanisms in a Blockchain-Based Healthcare Platform: A Mixed Method

Drawing on a mixed-method, this study aims to explore, identify, and investigate the various trust targets and their transfer mechanisms in a blockchain-based healthcare mutual aid platform. A qualitative online interview is first conducted to potential users in the online healthcare platform. Particularly, we identify three types of trust: trust in technology, trust in members, and trust in platform, that play salient roles in promoting users’ behavioral intention towards the online healthcare platform. Moreover, we find out that the three trust targets are formulated through different platform mechanisms. A preliminary research model is developed and a following-up research agenda is proposed for subsequent quantitative study
