Strategic Deviance and Accounting Conservatism  [PDF]
Rui Wang
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.85082
Abstract: This paper considers the influence of corporate strategic positioning on the firm’s accounting conservatism from the perspective of a company’s deviation from the industry’s conventional strategy, and selects China’s A stock market company as an initial research sample for empirical analysis from 2000 to 2016. Research shows that the greater the company’s strategic differences, the lower the accounting conservatism. Further studies have found that the negative correlation between corporate strategic differences and accounting conservatism is even more pronounced in private enterprises. In addition, from the perspective of the intensity of industry rules, this paper compares the degree of strategic deviance between state-owned enterprises and private enterprises, the results show that state-owned enterprises are subject to stronger constraints and the degree of strategic differences will be lower. This article focuses on the perspective of corporate strategic deviance and examines the role of non-accounting information in corporate accounting practices, and compares the strategic differences between state-owned enterprises and private enterprises from the perspective of the strength of industry constraints, which provides an effective means for the company’s external stakeholders, including creditors and investors, to use the company’s strategic information, and enriches the research on the reform of China’s property rights system.

Abstract: We present studies of the production and spectroscopy of some members of the B-hadron family. We reconstruct B ground states in their hadronic decay modes with a J/{\psi} or {\Upsilon} in the final state. These studies are based on the 2011 7 TeV dataset collected by the ATLAS detector.
Stereo Video Transmission Using LDPC Code  [PDF]
Rui GUO, Lixin WANG, Xiaoxia JIANG
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2008, DOI: 10.4236/ijcns.2008.13031
Abstract: Stereo video is widely used because it can provide depth information. However, it is difficult to store and transmit stereo video due to the huge data amount. So, high efficient channel encoding algorithm and proper transmission strategy is needed to deal with the video transmission over limited bandwidth channel. In this paper, unequal error protection (UEP) based on low density parity check (LDPC) code was used to transmit stereo video over wireless channel with limited bandwidth. Different correction level LDPC code was used according to the importance of video stream to reconstruction at the receiver. Simulation result shows that the proposed transmission scheme increases the PSNR of reconstructed image, and improves the subjective effect.
On Cubic Nonsymmetric Cayley Graphs  [PDF]
Jingjian Li, Bengong Lou, Rui Wang
Open Journal of Discrete Mathematics (OJDM) , 2013, DOI: 10.4236/ojdm.2013.31008
Abstract: Let \"\" be a connected Cayley graph of group G, then Γ is called normal if the right regular representation of G is a normal subgroup of , the full automorphism group of Γ. For the case where G is a finite nonabelian simple group and Γ is symmetric cubic Cayley graph, Caiheng Li and Shangjin Xu proved that Γ is normal with only two exceptions. Since then, the normality of nonsymmetric cubic Cayley graph of nonabelian simple group aroused strong interest of people. So far such graphs which have been known are all normal. Then people conjecture that all of such graphs are either normal or the Cayley subset consists of involutions. In this paper we give an negative answer by two counterexamples. As far as we know these are the first examples for the non-normal cubic nonsymmetric Cayley graphs of finite nonabelian simple groups.

Rui Guo, Cong Wang, Yugang Yang
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.54B127

A kind of 2-phase interleaving coupled magnetic integrated VRM is studied and the corresponding passivity-based control strategy is put forward. The model of this kind of magnetic integrated VRM is constructed, and the performance of this 2-phase interleaving magnetic integrated VRM of passivity-based control is verified by simulation experiments. The results proved that this kind of passivity-based control strategy can decrease the steady state current ripple and the dynamic output voltage under load disturbance.

Abstract: This paper analyzes the current situation of the Campus Express mode through the quantitative and qualitative methods to find the deficiencies in the existing model, and puts forward the improvement of the existing Campus Express mode. A new sorting method is adopted in the Campus unified distribution center for improving picking efficiency and solving the problem of “door-to-door” service. At the same time, the Platform of Campus Express—named “Crowdsourcing Express” mode is created, so that everyone can be involved in the activities of Campus Express. The plant can not only provide a better logistics service, but also combine commerce activities with Campus Express.
Targeting miRNAs in Osteoblast Differentiation under Malnutrition Conditions  [PDF]
Yuying Wang, Rui He, Liangjun Zhong
Journal of Biosciences and Medicines (JBM) , 2018, DOI: 10.4236/jbm.2018.65012
Abstract: Aims: Previous studies reported that reduced bone formation was identified in fasting adult female mice compared with the ad libitum control group. An increasing number of studies have shown that miRNAs contribute to bone homeostasis. Unfortunately, there are minor concerns about the underlying mechanisms in osteoblastic differentiation under malnutrition conditions. Methods: We investigated microRNAs (miRNAs) in osteoblastic differentiation under malnutrition conditions using high-throughput bioinformatics approaches. To screen for targeted microRNAs, sequences were quantified by aligning reads to miRbase using miRDeep2 software. Unadjusted p-values were calculated using the Student’s t-test. Genes with a p-value of <0.05 and log 2FC (fold change) ≥ 1 were considered differentially expressed genes (DEGs). DEGs were submitted to Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, respectively. Results: They were mainly enriched in biological process terms type and biological pathways, respectively. Particularly, we evaluated seven microRNAs, mir-494 3p, mir-466, mir-455, mir-708, mir-298, mir-92 and mir-224, which likely play roles in osteoblastogenesis in fasting adult mice. Conclusion: To our knowledge, this is the first study on the expression pattern of miRNA in osteoblasts of malnourished adult mice. These targeting miRNAs may provide a potential therapeutic approach to treat osteoporosis.
Highly versus Normally Attractive Person in Picture Reviews  [PDF]
Rui Wang, Baoying Feng, Siyun Chen
Journal of Service Science and Management (JSSM) , 2019, DOI: 10.4236/jssm.2019.123025
Abstract: This research explored the impact of person’s physical attractiveness in the picture reviews on women’s clothing purchase intention. The results showed that the physical attractiveness of the person in the picture reviews significantly affected the purchase intention of consumers, and the highly attractive person (HAP) could promote the purchase behavior of consumers. Body image was a mediator in the relationship between person’s physical attractiveness in picture reviews and consumers’ purchase intention, that is, people’s physical attractiveness indirectly influenced consumers’ purchase intention through body image. Finally, the influence of person’s physical attractiveness on consumers’ purchase intention was moderated by perceived similarity. When the consumers perceived that the people in the pictures were similar, HAP would promote their buying behavior. However, when the consumers perceived that the people in the pictures were dissimilar, HAP would reduce their buying behavior.
Access to food outlets and children's nutritional intake in urban China: a difference-in-difference analysis
Rui Wang, Lu Shi
Italian Journal of Pediatrics , 2012, DOI: 10.1186/1824-7288-38-30
Abstract: Using a longitudinal survey of households and communities in China, this study examines the effect of the urban built food environment (density of wet markets, density of supermarkets, and density of fast food restaurants) on children’s nutritional intake (daily caloric intake, daily carbohydrate intake, daily protein intake, and daily fat intake). Children aged 6–18 (n?=?185) living in cities were followed from 2004 to 2006, and difference-in-difference models are used to address the potential issue of omitted variable bias.Results suggest that the density of wet markets, rather than that of supermarkets, positively predicts children’s four dimensions of nutritional intake. In the caloric intake model and the fat intake model, the positive effect of neighborhood wet market density on children’s nutritional intake is stronger with children from households of lower income.With their cheaper prices and/or fresher food supply, wet markets are likely to contribute a substantial amount of nutritional intake for children living nearby, especially those in households with lower socioeconomic status. For health officials and urban planners, this study signals a sign of warning as wet markets are disappearing from urban China’s food environment.
