Xiaoming Chen,Mou Chen,Liqun Wang,Jun Shen,Jiapan Hu 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.11

This paper investigates the ℓ∞-induced output-feedback controller synthesis problem for discrete-time positive systems. For positive linear systems, a necessary and sufficient condition for stability and ℓ∞-induced performance is first put forward using a group of linear inequalities. Then, on the basis of these inequalities, theconditions on which static output-feedback controllers exist are set up, and to solve these conditions, a method of iterative convex optimization is provided. Moreover, a complete solution to the synthesis problem of the controller is proposed based on linear programming for positive systems with single output or input. Finally, two examples are presented to illustrate and verify the effective and applicable methods derived in this paper.

L-arginine and N-carbamoylglutamic acid supplementation enhance young rabbit growth and immunity by regulating intestinal microbial community

Sun, Xiaoming,Shen, Jinglin,Liu, Chang,Li, Sheng,Peng, Yanxia,Chen, Chengzhen,Yuan, Bao,Gao, Yan,Meng, Xianmei,Jiang, Hao,Zhang, Jiabao Asian Australasian Association of Animal Productio 2020 Animal Bioscience Vol.33 No.1

Objective: An experiment was conducted to determine the effects of L-arginine (L-Arg) and N-carbamoylglutamic acid (NCG) on the growth, metabolism, immunity and community of cecal bacterial flora of weanling and young rabbits. Methods: Eighteen normal-grade male weanling Japanese White rabbits (JWR) were selected and randomly divided into 6 groups with or without L-Arg and NCG supplementation. The whole feeding process was divided into weanling stage (day 37 to 65) and young stage (day 66 to 85). The effects of L-Arg and NCG on the growth, metabolism, immunity and development of the ileum and jejunum were compared via nutrient metabolism experiments and histological assessment. The different communities of cecal bacterial flora affected by L-Arg and NCG were assessed using high-throughput sequencing technology and bioinformatics analysis. Results: The addition of L-Arg and NCG enhanced the growth of weanling and young rabbit by increasing the nitrogen metabolism, protein efficiency ratio, and biological value, as well as feed intake and daily weight gain. Both L-Arg and NCG increased the concentration of immunoglobulin A (IgA), IgM, and IgG. NCG was superior to L-Arg in promoting intestinal villus development by increasing villus height, villus height/crypt depth index, and reducing the crypt depth. The effects of L-Arg and NCG on the cecal bacterial flora were mainly concentrated in different genera, including Parabacteroides, Roseburia, dgA-11_gut_group, Alistipes, Bacteroides, and Ruminococcaceae_UCG-005. These bacteria function mainly in amino acid transport and metabolism, energy production and conversion, lipid transport and metabolism, recombination and repair, cell cycle control, cell division, and cell motility. Conclusion: L-Arg and NCG can promote the growth and immunity of weanling and young JWR, as well as effecting the jejunum and ileum villi. L-Arg and NCG have different effects in the promotion of nutrient utilization, relieving inflammation and enhancing adaptability through regulating microbial community.

Seroprevalence of Toxoplasma gondii Infection among HIV/AIDS Patients in Eastern China

Guoqiang Shen,Xiaoming Wang,Hui Sun,Yaying Gao 대한기생충학열대의학회 2016 The Korean Journal of Parasitology Vol.54 No.1

Toxoplasmosis, a neglected tropical disease caused by the protozoan parasite Toxoplasma gondii, occurs throughout the world. Human T. gondii infection is asymptomatic in 80% of the population; however, the infection is life-threatening and causes substantial neurologic damage in immunocompromised patients such as HIV-infected persons. The major purpose of this study was to investigate the seroprevalence of T. gondii infection in subjects infected with HIV/AIDS in eastern China. Our findings showed 9.7% prevalence of anti-T. gondii IgG antibody in HIV/AIDS patients, which was higher than in intravenous drug users (2.2%) and healthy controls (4.7%), while no significant difference was observed in the seroprevalence of anti-Toxoplasma IgM antibody among all participants (P>0.05). Among all HIV/AIDS patients, 15 men (7.7%) and 10 women (15.9%) were positive for anti-T. gondii IgG antibody; however, no significant difference was detected in the seroprevalence of anti-Toxoplasma IgG antibody between males and females. The frequency of anti-Toxoplasma IgG antibody was 8.0%, 13.2%, 5.5%, and 0% in patients with normal immune function (CD4<SUP>+</SUP> T-lymphocyte count ≥500 cells/ml), immunocompromised patients (cell count ≥200 and <500 cells/ml), severely immunocompromised patients (cell count ≥50 and <200 cells/ml), and advanced AIDS patients, respectively (cell count <50 cells/ml), while only 3 immunocompromised patients were positive for anti-T. gondii IgM antibody. The results indicate a high seroprevalence of T. gondii infection in HIV/AIDS patients in eastern China, and a preventive therapy for toxoplasmosis may be given to HIV/AIDS patients based on CD4<SUP>+</SUP> T lymphocyte count.

Lishan Lv,Xiaoming Li,Genmei Liu,Ran Li,Qiliang Liu,Huifang Shen,Wei Wang,Chunyi Xue,Yongchang Cao 대한수의학회 2014 Journal of Veterinary Science Vol.15 No.2

Infectious bronchitis virus (IBV) poses a severe threat to thepoultry industry and causes heavy economic losses worldwide. Vaccination is the most effective method of preventing infectionand controlling the spread of IBV, but currently availableinactivated and attenuated virus vaccines have somedisadvantages. We developed a chimeric virus-like particle(VLP)-based candidate vaccine for IBV protection. The chimericVLP was composed of matrix 1 protein from avian influenzaH5N1 virus and a fusion protein neuraminidase (NA)/spike 1 (S1)that was generated by fusing IBV S1 protein to the cytoplasmicand transmembrane domains of NA protein of avian influenzaH5N1 virus. The chimeric VLPs elicited significantly higherS1-specific antibody responses in intramuscularly immunizedmice and chickens than inactivated IBV viruses. Furthermore,the chimeric VLPs induced significantly higher neutralizationantibody levels than inactivated H120 virus in SPF chickens. Finally, the chimeric VLPs induced significantly higher IL-4production in mice. These results demonstrate that chimericVLPs have the potential for use in vaccines against IBV infection.

EFFICIENT TiO2 NANOPARTICLES/NANORODS COMPOSITE ELECTRODES FOR DYE-SENSITIZED SOLAR CELLS

XIANWEI HUANG,PING SHEN,XIAOMING FENG,ZHUO TAN,SONGTING TAN,BIN ZHAO 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2012 NANO Vol.7 No.2

A new TiO2 nanoparticles/nanorods composite electrode was fabricated and applied in dye-sensitized solar cells (DSSCs). The TiO2 nanorods were obtained by grinding the electrospun TiO2 nanofibers mechanically. The composite photoanode of dye-sensitized solar cells was fabricated by using TiO2 nanoparticles (P25) and electrospun TiO2 nanorods. At the optimized condition, the power conversion efficiency (η) based on a triphenylamine dye (SD2) and a ruthenium dye (N719) are 8.28% and 8.80% under AM 1.5 illumination (100 mW ⋅ cm-2), respectively. The results show that the electrospun TiO2 nanorods in the composite photoanode improve the physicochemical properties and enhance the photovoltaic performances of solar cells.

Vascular bundle xylem water transport repression and cell anatomical structure differences may lead to berry cracking near the proximal end

Zhang Chuan,Cui Liwen,Shen Meng,Yadav Vivek,Zhong Haixia,Zhang Fuchun,Zhou Xiaoming,Wu Xinyu 한국원예학회 2024 Horticulture, Environment, and Biotechnology Vol.65 No.2

Grape berries often crack near the proximal end, which may be related to water absorption and their cellular anatomical structure. To study the relationship between water absorption, cell anatomical structures, and berry cracking near the proxi mal end, 49 varieties were selected. Eighteen were prone to cracking near the proximal end, while 31 were resistant. An in vitro soaking experiment on ripe berries measured the diff erence in berry-cracking degrees among diff erent varieties. In vitro staining was used to trace water absorption and paraffi n sections were prepared to observe and analyze the struc tural parameters of diff erent tissues. Results showed that the cracking rate and water uptake of the crack-prone berries were signifi cantly higher than those of the crack-resistant berries. Fruit prone to cracking was characterized by a thinner cuticle, epidermis, and sub-epidermis. After staining, it was found that dye absorption was limited to the berry near the proximal end. Other cell size parameters may also lead to cracking near the proximal end. By tracing water transport and analyzing diff erences in cell structure characteristics among varieties, we speculated that the vascular bundle xylem water transport repression and diff erences in cell anatomical structures may have led to berry cracking near the proximal end. The reasons for berry cracking near the proximal end were preliminarily explained, providing theoretical support for further screening of crack-resistant varieties.

High β-Glucosidase Secretion in Saccharomyces cerevisiae Improves the Efficiency of Cellulase Hydrolysis and Ethanol Production in Simultaneous Saccharification and Fermentation

Hong Ting Tang,Jin Hou,Yu Shen,Lili Xu,Hui Yang,Xu Fang,Xiaoming Bao 한국미생물생명공학회(구 한국산업미생물학회) 2013 Journal of microbiology and biotechnology Vol.23 No.11

Bioethanol production from lignocellulose is considered as a sustainable biofuel supply. However, the low cellulose hydrolysis efficiency limits the cellulosic ethanol production. The cellulase is strongly inhibited by the major end product cellobiose, which can be relieved by the addition of β-glucosidase. In this study, three β-glucosidases from different organisms were respectively expressed in Saccharomyces cerevisiae and the β-glucosidase from Saccharomycopsis fibuligera showed the best activity (5.2 U/ml). The recombinant strain with S. fibuligera β-glucosidase could metabolize cellobiose with a specific growth rate similar to the control strain in glucose. This recombinant strain showed higher hydrolysis efficiency in the cellulose simultaneous saccharification and fermentation, when using the Trichoderma reesei cellulase, which is short of the β-glucosidase activity. The final ethanol concentration was 110% (using Avicel) and 89% (using acid-pretreated corncob) higher than the control strain. These results demonstrated the effect of β-glucosidase secretion in the recombinant S. cerevisiae for enhancing cellulosic ethanol conversion.

Experimental and Theoretical Study on the Behavior of Cold-formed Stainless Steel Stub Columns

Gan-Ping Shu,Baofeng Zheng,Xiaoming Shen 한국강구조학회 2013 International Journal of Steel Structures Vol.13 No.1

This paper presents an experimental investigation on the behavior of cold-formed stainless steel stub columns under axial compression. Nineteen hollow section specimens of seven section types were tested. Geometric imperfections, material properties and full-range load-displacement curves were obtained. The test strengths were compared with the four design strengths, which are respectively calculated by using the American specification, the European specification, the design method proposed by Rasmussen in 2004, and the design method proposed by Gardner in 2008. The American specification, the European specification, and the design method proposed by Rasmussen are generally conservative. While the design method proposed by Gardner is relatively accurate. Based on the comparisons, modifications to Winter equation were derived to involve both the factors of the corner enhancement of the cold-formed members and the nonlinear property of stainless steel. The modified Winter equation can predict the strengths with low scatter.
