CUBIC B-SPLINE FINITE ELEMENT METHOD FOR THE ROSENAU-BURGERS EQUATION

Ge-Xing Xu,Chun-Hua Li,GUANG-RI PIAO 영남수학회 2017 East Asian mathematical journal Vol.33 No.1

Numerical solutions of the Rosenau-Burgers equation based on the cubic B-spline finite element method are introduced. The back- ward Euler method is used for discretization in time, and the obtained nonlinear algebraic system is changed to a linear system by the Newton’s method. We show that those methods are unconditionally stable. Two test problems are studied to demonstrate the accuracy of the proposed method. The computational results indicate that numerical solutions are in good agreement with exact solutions.

Ge, Xiao-Xiao,Xing, Mei-Yuan,Yu, Lan-Fang,Shen, Peng Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3

This meta-analysis was conducted to evaluate the association between intake of carotenoids and risk of esophageal cancer. A systematic search using PubMed, Cochrane Library, Web of Science, Scopus, CNKI, and CBM (updated to 6 May 2012) identified ten articles meeting the inclusion criteria with 1,958 cases of esophageal cancer and 4,529 controls. Higher intake of beta-carotene, alpha-carotene, lycopene, beta-cryptoxanthin, lutein, and zeaxanthin reduced esophageal cancer risk with pooled ORs of 0.58 (95% CI 0.44, 0.77), 0.81 (95% CI 0.70, 0.94), 0.75 (95% CI 0.64, 0.86), 0.80 (95% CI 0.66, 0.97), and 0.71 (95% CI 0.59, 0.87), respectively. In subgroup analyses, beta-carotene showed protective effects against esophageal adenocarcinoma in studies located in Europe and North America. Alpha-carotene, lycopene, and beta-cryptoxanthin showed protection against esophageal squamous cell cancer. This meta-analysis suggested that higher intake of carotenoids (beta-carotene, alpha-carotene, lycopene, beta-cryptoxanthin, lutein, and zeaxanthin) is associated with lower risk of esophageal cancer. Further research with large-sample studies need to be conducted to better clarify the potentially protective mechanisms of carotenoid associations risk of different types of esophageal cancer.

Zhao Jingyun,Xing Pu,Qin Ge 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.9

The complex equipment design scheme assimilability is affected by many factors. The analyzing process of it is both qualitative and quantitative. The process is fuzzy and qualitatively uncertain. For the purpose of objectively analyzing the complex equipment design scheme assimilability, an optimization model of complex equipment scheme assimilability based on extension superiority is proposed in this paper. The model first analyzes the influential factors of assimilability, establishing an optimal index system to standardize different types of optimal indexes and construct ideal extension fields of optimal indexes of assimilability based on extension theory. After that an extension correlation function model and an extension optimization model are constructed respectively based on extension positive fields and negative fields of assimilability optimal indexes. The size of extension optimization of assimilability optimal index of complex equipment design scheme helps acquire the optimal assembling scheme. The model is tested taking an assembling design scheme for a type of complex equipment as example.

Performance Analysis of Packet Transport Network Communication for Integrated Wide-Area Protection

Sheng-ming Ge,Z Q Bo,Lin Wang,Zhan-feng Fan,Xing Liu,Feng-quan Zhou 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.3

As a new protection, wide-area protection enables protective relaying, and automatic control based on electric power system network communications and comprehensive judgment of multi-point information, which plays an increasingly important role in the secure and stable operation of electric power system. Interaction of wide-area information relies on communication network featuring high reliability and low time delay. On the other hand, most service of power transformation station is gradually towards IP and data oriented, along with the development of smart grid. This paper aims to introduce the wide-area protection technology supported by Packet Transport Network (PTN) communication technology, with analyzing the QoS (Quality of Service) network assurance architecture of PTN network, which establishes three planes, including transport plane, management plane, and control plane, based on ASON (Automatically Switched Optical Network) technology. After demonstrating the QoS assurance system of PTN from traffic control and transmission route, this paper introduces PTN networking test. Based on detailed parameters in the test results, the transmission performance of PTN on time delay, protection, and time synchronization of various electric power communication services are analyzed, with showing that PTN can fully meet the requirements of electric power communication.

Expression of FMD Virus-like particles in yeast Hansenula polymorpha and immunogenicity of combine with CpG and Alumimun adjuvant

Jianhui Zhang,Jun Ge,Juyin Li,Jianqiang Li,Yong Zhang,Yinghui Shi,Jiaojiao Sun,Qiongjin Wang,Xiaobo Zhang,Xing-xu Zhao 대한수의학회 2023 Journal of Veterinary Science Vol.24 No.1

Background: Inactivated vaccines are limited in preventing foot-and-mouth disease (FMD) due to safety problems. Recombinant virus-like particles (VLPs) are an excellent candidate for a novel vaccine for preventing FMD, given that VLPs have similar immunogenicity as natural viruses and are replication- and infection-incompetent. Objectives: The 3C protease and P1 polyprotein of type O FMD virus (FDMV) was expressed in yeast Hansenula polymorpha to generate self-resembling VLPs, and the potential of recombinant VLPs as an FMD vaccine was evaluated. Methods: BALB/c mice were immunized with recombinant purified VLPs using CpG oligodeoxynucleotide and aluminum hydroxide gel as an adjuvant. Cytokines and lymphocytes from serum and spleen were analyzed by enzyme-linked immunosorbent assay, enzyme-linked immunospot assay, and flow cytometry. Results: The VLPs of FMD were purified successfully from yeast protein with a diameter of approximately 25 nm. The immunization of mice showed that animals produced high levels of FMDV antibodies and a higher level of antibodies for a longer time. In addition, higher levels of interferon-γ and CD4+ T cells were observed in mice immunized with VLPs. Conclusions: The expression of VLPs of FMD in H. polymorpha provides a novel strategy for the generation of the FMDV vaccine.

MuDeepNet: Unsupervised Learning of Dense Depth, Optical Flow and Camera Pose Using Multi-view Consistency Loss

Jun-Ning Zhang,Qun-Xing Su,Peng-Yuan Liu,Hong-Yu Ge,Ze-Feng Zhang 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.10

We take formulate structure from motion as a learning problem, and propose an end-to-end learning framework to calculate the image depth, optical flow, and the camera motion. This framework is composed of multiple encoder-ecoder networks. The key part of the network structure is the FlowNet, which can improve the accuracy of the estimated camera ego-motion and depth. As with recent studies, we use an end-to-end learning approach with multi-view synthesis as a variety of supervision, and proposes multi-view consistency losses to constrain both depth and camera ego-motion, requiring only monocular video sequences for training. Compared to the recently popular depth-estimation-networks using a single image, our network learns to use motion parallax correction depth. Although MuDeepNet training requires the use of two adjacent frames to obtain motion parallax, it is tested by using a single image. Thus, MuDeepNet is a monocular system. The experiments on KITTI dataset show our MuDeepNet outperforms other methods.

Yu‑Jing He,Lei Xing,Peng‑Fei Cui,Jia‑Liang Zhang,Jian‑Bin Qiao,Cheng‑Qiong Luo,Ge Jiang,Hu‑Lin Jiang 한국약제학회 2017 Journal of Pharmaceutical Investigation Vol.47 No.2

Here, we demonstrate a co-delivery system constructed by integrating chemotherapeutic molecules into branched polymeric prodrug which can condense nucleic acids. Demethylcantharidate (DCA) was chosen as a model drug and premodified through nucleophilic substitution reaction by its two carboxylic groups with allyl chloride. The synthesized intermediate (DCA-dially) was then used to polymerize with tris (2-aminoethyl) amine (TAEA) through progressively ammonolysis reaction. The obtained poly (DCA-alt-TAEA) (DCAT) was used to pack PDCD4 into spherical-like nanoparticles through electrostatic interaction. Gel retardation assays implied that DCAT could integrate DNA at the weight ratio of 1 and protect it from digestion by nuclease. Acid-base titration experiments showed that DCAT obtained preferable buffering capability which was beneficial for the endosomal escape of DCAT/PDCD4 complexes. Cellular tests involving gene transfection efficiency and cytotoxicity indicated that DCA and PDCD4 co-delivered by the complexes significantly and synergistically suppressed the viability of SMMC-7721 cells. These results suggest that integrating chemotherapeutic molecules into nucleic acid-packing polymeric prodrug as cationic polymer/PDCD4 complexes is a highly efficient way to co-deliver chemotherapeutic drugs and nucleic acids for cancer therapy.
