Abstract: A k-quantum nonlinear Jaynes-Cummings model for two trapped ions interacting with laser beams resonant to k-th red side-band of center-of-mass mode, far from Lamb-Dicke regime, has been obtained. The exact analytic solution showed the existence of quantum collapses and revivals of the occupation of two atoms.
Reconstructing propagation networks with temporal similarity metrics
Hao Liao,An Zeng
Computer Science , 2014,
Abstract: Node similarity is a significant property driving the growth of real networks. In this paper, based on the observed spreading results we apply the node similarity metrics to reconstruct propagation networks. We find that the reconstruction accuracy of the similarity metrics is strongly influenced by the infection rate of the spreading process. Moreover, there is a range of infection rate in which the reconstruction accuracy of some similarity metrics drops to nearly zero. In order to improve the similarity-based reconstruction method, we finally propose a temporal similarity metric to take into account the time information of the spreading. The reconstruction results are remarkably improved with the new method.
Research on the Impact of Social Circles on Self-Brand Connection: Regulation of Self-Awareness and Brand Value  [PDF]
Shenghong Ye, Jia Li, Zhaobin Zeng, Shuang Hao
Open Journal of Business and Management (OJBM) , 2015, DOI: 10.4236/ojbm.2015.32015
Abstract: In this article we categorize social circles by sense of belonging and explore the relation between social circle types and self-brand connection (SBC). Furthermore, we research the mechanism of how the impact of social circles on consumers’ SBC is influenced by self-awareness within a particular social circle and by brand value. Our findings show that 1) the sense of belonging toward social circles has positive influence on SBC; 2) consumers’ self-awareness moderates the impact of social circles on SBC; 3) the type of brand value moderates the impact of social circles on SBC. Finally, several suggestions are derived for local management practice in China.
Towards an objective ranking in online reputation systems: the effect of the rating projection
Hao Liao,An Zeng,Yi-Cheng Zhang
Computer Science , 2014,
Abstract: Online reputation systems are commonly used by e-commerce providers nowadays. In order to generate an objective ranking of online items' quality according to users' ratings, many sophisticated algorithms have been proposed in the literature. In this paper, instead of proposing new algorithms we focus on a more fundamental problem: the rating projection. The basic idea is that even though the rating values given by users are linearly separated, the real preference of users to items between different values gave is nonlinear. We thus design an approach to project the original ratings of users to more representative values. This approach can be regarded as a data pretreatment method. Simulation in both artificial and real networks shows that the performance of the ranking algorithms can be improved when the projected ratings are used.
Predicting missing links via correlation between nodes
Hao Liao,An Zeng,Yi-Cheng Zhang
Computer Science , 2014,
Abstract: As a fundamental problem in many different fields, link prediction aims to estimate the likelihood of an existing link between two nodes based on the observed information. Since this problem is related to many applications ranging from uncovering missing data to predicting the evolution of networks, link prediction has been intensively investigated recently and many methods have been proposed so far. The essential challenge of link prediction is to estimate the similarity between nodes. Most of the existing methods are based on the common neighbor index and its variants. In this paper, we propose to calculate the similarity between nodes by the correlation coefficient. This method is found to be very effective when applied to calculate similarity based on high order paths. We finally fuse the correlation-based method with the resource allocation method, and find that the combined method can substantially outperform the existing methods, especially in sparse networks.
Detection of Three Common Organic Explosives Using Capillary Electrophoresis  [PDF]
Hong Zhou, Zhanfang Liu, Yuyou Sun, Ling Zeng, Hongcheng Mei, Jianzhong Xu, Baoyuan Guo, Hongxia Hao
Journal of Materials Science and Chemical Engineering (MSCE) , 2016, DOI: 10.4236/msce.2016.46003
Abstract:
In this article, a detection method for organic explosives by capillary electrophoresis (CE) is developed based on previous detection techniques. Firstly, a buffer solution consisting of 50 mmol·L-1 sodium dodecyl sulfate (SDS), 20 mmol·L-1 sodium tetraborate and 5% methanol was prepared and the UV detection in this buffer solution was conducted for three common organic explosives, including TNT, DNT and PETN. Then, the capillary UV detection method was investigated in terms of the transition time repeatability, the linear relationship between mass concentration and peak area and the limit of detection. The results revealed good reliability and stability of this method. In addition, these samples were characterized by photodiode array detector (PDA) to verify the qualitative results of UV detection.

Mei Ge, Xihong Hou, Shimeng Li, Kunpeng Liu, Ziyi Han, Siyu Hao, Zhongliang Zeng, Yingchun Zhang
Pharmacology & Pharmacy (PP) , 2019, DOI: 10.4236/pp.2019.103013
Abstract:
Cortex Moutan (Paeonia suffruticosa Andr.) is a common traditional Chinese medicine and has been widely used in clinic for 2000 years in China. As sources for this crude drug are always mixed with other species, many cultivars on herbal market may lead to quality instability. Multi-component quantitative analysis is an efficient method to reflect chemical profiles of herb medicine and is always taken as the main method for quality evaluation. So, the aim of this work is to develop analytical method to quantify paeonol, paeoniflorin, gallic acid, oxypaeoniflorin, benzoylpaeoniflorin and paeonolide in Cortex Moutan (CM) to evaluate the chemical qualities of CM from different species or cultivars. Besides, we also study the intestinal absorption characteristics of paeonol and paeoniflorin for further pharmacological evaluation. In the present study, all of the standard markers were performed on an Ecosil C18 (250 mm × 4.6 mm, 5 μM, Lubex Co., Guangzhou, China) with linear gradient elution of 0.2% formic acid water and acetonitrile. The proposed method was applied to analyze 50 batches of samples with acceptable linearity (R2, 0.9995 - 0.9999), precisions (RSD, 0.47% - 2.08%), repeatability (RSD, 039% - 2.63%), stability (RSD, 0.52% -

Abstract: The impact of the interannual variability (IAV) of vegetation on the IAV of evapotranspiration is investigated with the Community Land Model (CLM3.0) and modified Dynamic Global Vegetation Model (DGVM). Two sets of 50-year off-line simulations are used in this study. The simulations begin with the same initial surface-water and heat states and are driven by the same atmospheric forcing data. The vegetation exhibits interannual variability in one simulation but not in the other simulation. However, the climatological means for the vegetation are the same. The IAV of the 50-year annual total evapotranspiration and its three partitions (ground evaporation, canopy evaporation, and transpiration) are analyzed. The global distribution of the evapotranspiration IAV and the statistics of evapotranspiration and its components in different ecosystems show that the IAV of ground evaporation is generally large in areas dominated by grass and deciduous trees, whereas the IAV of canopy evaporation and transpiration is large in areas dominated by bare soil and shrubs. For ground evaporation, canopy evaporation, and transpiration, the changes in IAV are larger than the mean state over most grasslands and shrublands. The study of two sites with the same IAV in the leaf area index (LAI) shows that the component with the smaller contribution to the total evapotranspiration is more sensitive to the IAV of vegetation. The IAV of the three components of evapotranspiration increases with the IAV of the fractional coverage (FC) and the LAI. The ground evaporation IAV shows the greatest increase, whereas the canopy evaporation shows the smallest increase.
