On Rousseau’s Love Outlook and His Civilian Complex  [PDF]
Xiaoying Li, Yingfei Yuan
Advances in Literary Study (ALS) , 2015, DOI: 10.4236/als.2015.34018
Abstract: Rousseau had some peculiar love experiences which many people couldn’t understand, especially the experience with the servant Therese le Vasseur. So in the article, I explored his life background, his love experiences and analyzed his love outlook. Certainly, his love outlook was related to his love experiences and his love experiences also were related to his civilian complex. I might say that his love experiences, love outlook and civilian complex answered people’s doubt that was why he chose Therese le Vasseur to spend his rest of his life.
Changes of Essential Mineral Elements Contents in Response to Cu2+ Treatment in Sagittaria sagittifolia  [PDF]
Xiaoying Xu, Yikun Xu, Yuan Chi, Penghe Wang, Guoxin Shi
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.67063
Abstract: Changes of various mineral elements (P, K, Ca, Mg, Fe, Mn, Zn and Na) contents in roots and leaves of S. sagittifolia were studied with treatment of different Cu2+ concentrations (5 μM, 10 μM, 20 μM and 40 μM) after 15 days. The results showed that: 1) Cu accumulated in roots of S. sagittifolia in large quantities, while Cu content in leaves showed no significant change; 2) It can be seen from the changes of macroelements that Cu2+ treatments had inhibited the absorption of P, K, Ca, Mg in roots of S. sagittifolia, but the contents of P, K and Mg in leaves were higher than those in the roots in all Cu2+ treatment groups; 3) It can be seen from the changes of microelements that Cu2+ treatment promoted the absorption of Fe, inhibited absorption of Mn, Zn and Na in roots of S. sagittifolia, and hindered the transport of various micro-elements from roots to leaves. In all the Cu2+ treatment groups, contents of Fe, Mn, Zn and Na in leaves were lower than those in the roots; 4) The critical concentration of Cu2+ to S. sagittifolia was 5 μM. It could be seen from the above results that exogenous added Cu2+ of different concentrations broke the balance of various mineral elements in S. sagittifolia, which would exert a significant impact on numerous metabolic pathways and physiological processes.
A Study on Emotional Metaphors in Yellow Emperor  [PDF]
Xiaoying Li
Open Journal of Modern Linguistics (OJML) , 2015, DOI: 10.4236/ojml.2015.55042
Abstract: The theoretical system of the medical classic Yellow Emperor reflects the cultural levels of the Warring States Period, and social history, and science and technology development long after the Qin and Han dynasty, and it also reflects the Chinese traditional mode of thinking. From the perspective of cognitive linguistics, study on the book Yellow Emperor’s emotional metaphor paradigm, cognitive mechanisms and meaning construction, it is found that emotional metaphor is a more general theory which explains the important thinking of physiology, pathology, therapy and health, etc., but it is also found that as long as it is related to disease and health, there will appear magical implication of emotional metaphors.

Hu Jianguang,Zhao Xiangshan,Yuan Ziqiang,Qian Xiaoying,Yang Jinshui
Chinese Science Bulletin , 1998, DOI: 10.1007/BF02884536
Abstract: It was demonstrated that parental gene expression of maize in hybrid genetic background was different from that in their inbred lines. RT-PCR revealed a cDNA overexpressed in hybrid maize. The cDNA was reamplified and used to screen a corresponding cDNA library. A full length of a cDNA insert ZH01 was isolated and shown to have an open reading frame encoding 414a. a. Sequence comparison shows that ZH01 has extremely high similarity with the previously reported plant initiator factor elF-4A and distinct difference from another maize elF-4A gene MIF4A. Ovcrexpression of ZH01 in hybrid may involve vigorous growth of hybrid maize seedlings.
Theoretical Analysis of Cyclic Frequency Domain Noise and Feature Detection for Cognitive Radio Systems
Gan Xiaoying,Shan Da,Zhou Yuan,Zhang Wei,Qian Liang
Mathematics , 2009,
Abstract: In cognitive radio systems, cyclostationary feature detection plays an important role in spectrum sensing, especially in low SNR cases. To configure the detection threshold under a certain noise level and a pre-set miss detection probability Pf, it's important to derive the theoretical distribution of the observation variable. In this paper, noise distribution in cyclic frequency domain has been studied and Generalized Extreme Value (GEV) distribution is found to be a precise match. Maximum likelihood estimation is applied to estimate the parameters of GEV. Monte Carlo simulation has been carried out to show that the simulated ROC curve is coincided with the theoretical ROC curve, which proves the efficiency of the theoretical distribution model.

Xiaoying Li, Wenquan Ling
Open Journal of Business and Management (OJBM) , 2015, DOI: 10.4236/ojbm.2015.31010
Abstract: Framing effect is an understanding and assessment that individual implements different behaviors when facing to the multiple choice that expressing the same meaning. Previously, scholars went through numerous empirical studies regarding impact of the method as well as environment in making decision of online purchasing [1]-[4]. Also, scholars have proved that there are complex influences of psychological factors when consumers make decisions of shopping. Therefore, the article aims to analyze the impact of faming effect in e-commerce when consumers make decisions so as to summarize the shortage in academic and practical aspects.

Immunogenicity and virus-like particle formation of rotavirus capsid proteins produced in transgenic plants
YanMei Yang,Xia Li,Hui Yang,Yuan Qian,You Zhang,RongXiang Fang,XiaoYing Chen
Science China Life Sciences , 2011, DOI: 10.1007/s11427-010-4104-3
Abstract: The human pathogen, group A rotavirus, is the most prevalent cause of acute infantile and pediatric gastroenteritis worldwide, especially in developing countries. There is an urgent demand for safer, more effective and cheaper vaccines against rotavirus infection. Plant-derived antigens may provide an exclusive way to produce economical subunit vaccines. Virus-like particles, constituting viral capsid proteins without viral nucleic acids, are considered a far safer candidate compared with live attenuated viral vaccines. In this study, the rotavirus capsid proteins VP2, VP6 and VP7 were co-expressed in transgenic tobacco plants, and their expression levels, formation of rotavirus-like particles (RV VLPs) and immunogenicity were extensively studied. Quantitative real-time RT-PCR and Western blot analysis revealed that the expression level of vp6 was the highest while vp7 was expressed at the lowest levels. The RV VLPs were purified from transgenic tobacco plants and analyzed by electron microscopy and Western blot. Results indicated that the plant-derived VP2, VP6 and VP7 proteins self-assembled into 2/6 or 2/6/7 RV VLPs with a diameter of 60–80 nm. When orally delivered into mice with cholera toxin as an adjuvant, the total soluble protein extracted from transgenic tobacco plants induced rotavirus-specific antibodies comparable with those of attenuated rotavirus vaccines, while VP 2/6/7 induced higher serum IgG and fecal IgA titers compared with VP 2/6.

Abstract: Using the technique of ultraviolet absorption spectrometry and fluorescence spectrometry, this study examined the interactions between bromoform(CHBr3) and calf thymus DNA(ctDNA) with or without Cu2+, Co2+, Cd2+ and Mg2+individually or concurrently. The results show complex ground-state reactions among the metal ions, CHBr3and ctDNA, as evidenced by the variations in the peak of UV absorption intensity and shape in the ctDNA-ethidium bromide system. The interactions cause fluorescence quenching to various extents. The presence of Cu2+, Co2+, Cd2+ (ranked by decreasing strength) weakened the binding between CHBr3 and ctDNA, while Mg2+enhanced such binding. In addition, the simultaneous presence of the four metal ions resulted in intermediate impact, varying from the effect of the individual metal ions. The results suggest that CHBr3 is likely to intercalate into ctDNA and such intercalations mainly depend on the relative binding affinity of a metal ion to the bases and to the phosphate groups in DNA.
