The aim of this study is to identify the data traffic capacity of 3G mobile communication networks, especially of cdma2000-1X networks. Three-layered ON/OFF traffic model is used to describe the dynamics of data traffics and the process of data transmission such as packet scheduling. We construct a simulator fully incorporating packet handling process of cdma2000-1X data network as well as three-layered ON/OFF traffic model describing the behavior of source data traffics. To get influence of traffic parameters on performance measures, the extensive simulations were performed for several data sets which are obtained from real trace data or previous studies. The experimental results show that the engineered throughput satisfying QoS criteria is approximately 20% of total capacity. Finally, some proposals to improve the system capacity are followed.

Deubiquitinases (DUBs) and noncoding RNAs have been the subjects of recent extensive studies regarding their roles in lung cancer, but the mechanisms involved are largely unknown. In our study, we used The Cancer Genome Atlas data set and bioinformatics analyses and identified USP21, a DUB, as a potential contributor to oncogenesis in nonsmall-cell lung cancer (NSCLC). We further demonstrated that USP21 was highly expressed in NSCLCs. We then conducted a series of in vitro and in vivo assays to explore the effect of USP21 on NSCLC progression and the underlying mechanism involved. USP21 promoted NSCLC cell proliferation, migration, and invasion and in vivo tumor growth by stabilizing a well-known oncogene, Yin Yang-1 (YY1), via mediating its deubiquitination. Furthermore, YY1 transcriptionally regulates the expression of SNHG16. Moreover, StarBase bioinformatics analyses predicted that miR4500 targets SNHG16 and USP21. A series of in vitro experiments indicated that SNHG16 increased the expression of USP21 through miR-4500. In summary, the USP21/YY1/SNHG16 axis plays a role in promoting the progression of NSCLC. Therefore, the USP21/YY1/SNHG16/miR-4500 axis may be a potential therapeutic target in NSCLC treatment.

Behavior of three-tube buckling-restrained brace with circumference pre-stress in core tube

Yang Li,Haiyan Qu,Shaowen Xiao,Peijun Wang,Yang You,Shuqing Hu 국제구조공학회 2019 Steel and Composite Structures, An International J Vol.30 No.2

The behavior of a new Three-Tube Buckling-Restrained Brace (TTBRB) with circumference pre-stress (σθ,pre) in core tube are investigated through a verified finite element model. The TTBRB is composed of one core tube and two restraining tubes. The core tube is in the middle to provide the axial stiffness, to carry the axial load and to dissipate the earthquake energy. The two restraining tubes are at inside and outside of the core tube, respectively, to restrain the global and local buckling of the core tube. Based on the yield criteria of fringe fiber, a design method for restraining tubes is proposed. The applicability of the proposed design equations are verified by TTBRBs with different radius-thickness ratios, with different gap widths between core tube and restraining tubs, and with different levels of σθ,pre. The outer and inner tubes will restrain the deformation of the core tube in radius direction, which causes circumference stress (σθ) in the core tube. Together with the σθ,pre in the core tube that is applied through interference fit of the three tubes, the yield strength of the core tube in the axial direction is improved from 160 MPa to 235 MPa. Effects of gap width between the core tube and restraining tubes, and σθ,pre on hysteretic behavior of TTBRBs are presented. Analysis results showed that the gap width and the σθ,pre can significantly affect the hysteretic behavior of a TTBRB.

Friendship Influence on Mobile Behavior of Location Based Social Network Users

Yang Song,Zheng Hu,Xiaoming Leng,Hui Tian,Kun Yang,Xin Ke 한국통신학회 2015 Journal of communications and networks Vol.17 No.2

In mobile computing research area, it is highly desirable to understand the characteristics of user movement so that the user friendly location aware services could be rendered effectively. Location based social networks (LBSNs) have flourished recently and are of great potential for movement behavior exploration and datadriven application design. While there have been some efforts on user check-in movement behavior in LBSNs, they lack comprehensive analysis of social influence on them. To this end, the socialspatial influence and social-temporal influence are analyzed synthetically in this paper based on the related information exposed in LBSNs. The check-in movement behaviors of users are found to be affected by their social friendships both from spatial and temporal dimensions. Furthermore, a probabilistic model of user mobile behavior is proposed, incorporating the comprehensive social influence model with extent personal preference model. The experimental results validate that our proposed model can improve prediction accuracy compared to the state-of-the-art social historical model considering temporal information (SHM+T), which mainly studies the temporal cyclic patterns and uses them to model user mobility, while being with affordable complexity.

A comparative study on population development patterns of Sogatella furcifera between tropical and subtropical areas

Yang Hu,Jia-An CHENG,Zengrong Zhu,Kong Luen Heong,Qiang Fu,Jiachun He 한국응용곤충학회 2014 Journal of Asia-Pacific Entomology Vol.17 No.4

The White-backed Planthopper (WBPH), Sogatella furcifera (Horváth (Hemiptera: Delphacidae)) has been the most serious pest threatening rice production in Asia since the late 1970s. A series of field experiments using the same research protocol was carried out to compare the effects of main environmental factors on population development of WBPH in tropical (Philippines) and subtropical (China) areas in 2010–2012 and to provide further evidences of ecological mechanisms involved that cause frequent outbreak in subtropical rice. Outcomes showed that WBPH population in subtropical area could be characterized as the higher population growth rates and higher peak densities. The average growth rate (116.60 ± 46.16) in subtropical area was significantly higher than that in tropical area (24.02± 11.25). The higher realized fecundity in subtropical area indicated that the higher growth rates and higher peak densities were mainly related to the poor natural regulating forces in subtropical area. Our results showed that resistant variety could significantly reduce the peak density in subtropical areas, but not in tropical areas. We inferred that the reason for not detecting the effect of resistant variety in tropical area was due to the dominant controlling effects provided by natural enemies,which means that the natural regulating effect in tropical areawas strong enough to disguise the effects of resistant variety. The significant interactions between plant resistance and location demonstrated that integration of natural enemies and use of plant resistance could play important roles for reducing outbreak frequency of WBPH effectively in subtropical rice.

Numerical Study of Temperature Distribution Control in Precision Glass Molding Furnace

Yang Hu,Lianguan Shen,Jian Zhou,Mujun Li 한국정밀공학회 2018 International Journal of Precision Engineering and Vol.19 No.6

In a precision glass molding process, glass preform is compressed at a high temperature well above its transition temperature and the temperature distribution inside plays an important role in determining the quality of final products. In this research, a 2D axisymmetric numerical heat transfer model, integrated with an innovative PID control subroutine, was employed for simulating the temperature control process and obtaining transient temperature distribution in the glass preform. Feasibility of this method was validated by experiments with good agreements. Finally, influence of air gap between glass preform and upper mold as well as temperature control mode were investigated. The results showed that temperature difference of the molds had a severer influence on the temperature distribution of glass preform with the decrease of air gap. In addition, a two-point control strategy was demonstrated as a valid method to improve the temperature uniformity in the glass preform.

Yang Hu,Shanyi Shi,Lu Lu,Chunying Teng,Sumei Yu,Xin Wang,Min Yu,Jinsong Liang,Juanjuan Qu 한국고분자학회 2017 Macromolecular Research Vol.25 No.3

Excessive reactive oxygen species is implicated in the etiology and pathology of many acute and chronic diseases. Selenium acts as an antioxidant and stimulates the creation of more antioxidants. Selenizing modification polysaccharides potentiate the physiological and pharmacological activities of selenium and polysaccharide. In this study, Inonotus obliquus polysaccharide (IOP) extracted from cultured mycelia was modified into Se-IOP by HNO3- Na2SeO3 method. The characteristics and antioxidant activity of IOP and Se-IOP were comparatively investigated. The result showed that polysaccharide content of purified IOP was 98.9%. The selenium content of Se-IOP was 0.71 mg/g. Both IOP and Se-IOP were homogeneous polysaccharides with a molecular weight of 37.354 and 28.071 kDa, respectively depicted in high performance gel permeation chromatogram (HPGPC). Moreover, both IOP and Se- IOP were composed of Man, Glu, and Gal with a molar ratio of 7.7:32.6:23.3 and 8.3:32.1:22.7, respectively determined by high performance liquid chromatography (HPLC). The characteristic absorption peak of O-Se-O, Se=O and C-O-Se appeared at 1026.75, 772.82, and 652.29 cm-1 respectively in FT-IR spectrum of Se-IOP indicating the success of selenylation. NMR spectrum further confirmed the anomeric carbon signals and chemical shifts in IOP and Se-IOP. These variations induced by selenylation may lead to a higher antioxidant activity of Se-IOP on scavenging hydroxyl, 2,2-diphenyl-1-picryl-hydrazyl (DPPH) and superoxide radical than that of IOP. Furthermore, Se- IOP treatment could also reduce oxidant damage by decreasing the level of malondialdehyde (MDA) and increasing the activities of superoxidedismutase (SOD) and GSH-Px in mice.
