Yingying Wu,Yuangong Sun 제어로봇시스템학회 2013 제어로봇시스템학회 국제학술대회 논문집 Vol.2013 No.10

This paper addresses the average consensus problem of multi-agent systems with neutral dynamics for the first time. By decoupling the neutral multi-agent system in terms of the eigenvalues of the Laplacian matrix, we establish necessary and sufficient conditions for average consensus of neutral multi-agent systems in undirected networks. For the particular case of constant delay, a least upper bound of the allowable time delay for consensus is given.

Wu Yingying,Yang Ruiheng,Baodapeng 한국버섯학회 2017 버섯 Vol.21 No.2

Hypsizygus marmoreus (Peck) H.E. Bigelow is a typical white-rot fungus and is widely cultivated in China and Japan. In this study, the genome of a monokaryon strain HM26-F1 was sequenced using Illumina and Pacbio platforms. The genome sequences of 32,238,363 bp with 49.40% G+C content were obtained and 14,443 gene models coding for proteins were determined. The divergence time was 144 million years ago (MYA) and diverged from other fungi belonging to Agaricales around the late of Jurassic Period. 363 carbohydrate-active enzymes (CAZymes) genes were detected in this genome. And there were higher number of class II peroxidases (11) and multicopper oxidases (22) for degrading lignin. In addition, 418 genes were enriched involving in purine metabolism for IMP and GMP synthesis. And, there were 7 secondary metabolite clusters in the genome, including 3 terpene, 2 polyketide biosynthase, 1 nonribosomal peptide synthetase and 1 siderophore. Combining Hiseq 2500 and Pacbio platforms resulted in a more complete and less fragmented genome. H. marmoreus had high abilities to degrade lignocellulose. IMP and GMP may be the basis of the crab flavor. Information obtained from this study enhances our knowledge about degradation mechanisms of lignocellulose and secondary metabolism.

Yingying Wu,Xin Wang,Shuaishuai Liu,Hao Luo,Qiang Lin 한국유전학회 2020 Genes & Genomics Vol.42 No.2

Background The evolution of male pregnancy is the most distinctive characteristic of syngnathids, and they were recognized as flagship species for marine conservation. Genus Halicampus is an important branch of syngnathid fishes that has not received the attention it deserves. Objective To sequence the mitochondrial genome of Halicampus grayi, and investage the genetic structure of its populations. Methods Degenerate primers were designed to amplify the entire mitochondrial genome of H. grayi. The phylogenetic relationship between H. grayi and other syngnathids were conducted using maximum-likelihood method. Population genetic structure of three geographic population of H. grayi were determined using median-joining haplotype network based on COI and Cytb sequences. Results The complete mitochondrial genome of Halicampus grayi was assembled into a 17,059 bp circular sequence, which contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 D-loop region. The overall base composition of H. grayi is 29.93% A, 29.31% T, 16.23% G and 24.54% C, with a slight A + T rich feature (59.24%). Phylogenetic analysis indicated that H. grayi has a close relationship with Trachyrhamphus serratus. Population genetic analysis revealed a relatively high genetic diversity across different geographic populations of H. grayi, and the results of median-joining haplotype network indicated a lack of structure in populations of H. grayi. Conclusion The mitogenome of H. grayi will provided important information about the origin and evolution issues of syngnathid fishes, and the high-level genetic diversity detected in their populations will provide insight into the gene flow pattern of marine fishes.

An Integrated Approach of Real-time Hand Gesture Recognition Based on Feature Points

Yingying She,Yunzhe Jia,Ting Gu,Qun He,Qingqiang Wu 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.4

Hand Gesture recognition systems enable people to interact with digital systems naturally. Due to the spread of body motion capture device, depth information is available for getting more delicate and effective gesture recognition results. However, due to the limitation of devices such as Microsoft Kinect, it is still very difficult to obtain hand gesture information in rela-time. This paper proposes an integrated approach of real-time hand gesture recognition based on feature points. It explains our solutions for hand segmentation and feature points abstraction based on real-time motion captured images. Having been tested with a series of applications, our method is proved to be robust and effective, and suitable for further extension in real-time hand gesture recognition systems.

Yingying Ye,Zeqin Fu,Yunfang Tian,Jiji Li,Baoying Guo,Zhenming Lv,Changwen Wu 한국유전학회 2018 Genes & Genomics Vol.40 No.11

Pelagic larval dispersal habits influence the population genetic structure of marine mollusk organisms via gene flow. The genetic information of the clam Gomphina aequilatera (short larval stage, 10 days) which is ecologically and economically important in the China coast is unknown. To determine the influence of planktonic larval duration on the genetic structure of G. aequilatera. Mitochondrial markers, cytochrome oxidase subunit i (COI) and 12S ribosomal RNA (12S rRNA), were used to investigate the population structure of wild G. aequilatera specimens from four China Sea coastal locations (Zhoushan, Nanji Island, Zhangpu and Beihai). Partial COI (685 bp) and 12S rRNA (350 bp) sequences were determined. High level and significant FST values were obtained among the different localities, based on either COI (FST = 0.100–0.444, P < 0.05) or 12S rRNA (FST = 0.193–0.742, P < 0.05), indicating a high degree of genetic differentiation among the populations. The pairwise Nm between Beihai and Zhoushan for COI was 0.626 and the other four pairwise Nm values were > 1, indicating extensive gene flow among them. The 12S rRNA showed the same pattern. AMOVA test results for COI and 12S rRNA indicated major genetic variation within the populations: 77.96% within and 22.04% among the populations for COI, 55.73% within and 44.27% among the populations for 12S rRNA. A median-joining network suggested obvious genetic differentiation between the Zhoushan and Beihai populations. This study revealed the extant population genetic structure of G. aequilatera and showed a strong population structure in a species with a short planktonic larval stage.

Yingying Wang,Linli Zhu,Xiaohong Wang,Wanru Zheng,Chen Hao,Chenglong Jiang,Jingbo Wu 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.61 No.-

A low-cost adsorbent, aminated calcium lignosulfonate (ACLS) was prepared and successfully applied to the adsorption of Congo red and the Titan yellow dyes. The adsorbent was characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), elemental mapping images (EMIs) and Brunauer–Emmett–Teller (BET) analysis. And the efficiency of ACLS for the removal of Congo red and the Titan yellow dyes was evaluated by several factors, such as temperature, pH, adsorbent dose, contact time and initial concentration of dyes solution. And the test ranges of temperature, pH, adsorbent dose, contact time and initial concentration of dye solution were 25–45 °C, 2–12, 0.005–0.05 g, 1–48 h, 10–200 mg L−1, respectively. The adsorption results demonstrated a good ability to remove dye with the removal rates of 97% and 91% for 30 mg L−1 Congo red and 40 mg L−1 Titan yellow, respectively. The adsorption kinetic and adsorption isotherms can be well described by the pseudo second order kinetic and the Langmuir isotherm model for the both dyes, respectively. Moreover, the maximum adsorption capacity of Congo red and Titan yellow reached 258.4 mg g−1 and 190.1 mg g−1 in the study of the Langmuir adsorption isotherm, respectively. Thermodynamic studies show that the adsorption of the two dyes is a spontaneous endothermic process. The results indicate that the ACLS has the potential to be used in the treatment of dye wastewater.

Carboxymethylated chitosan alleviated oxidative stress injury in retinal ganglion cells via IncRNA-THOR/IGF2BP1 axis

Xiaoli Wu,Yingying Liu,Yun Ji 한국유전학회 2021 Genes & Genomics Vol.43 No.6

Background Glaucoma is an advanced nerve disorder described by the deterioration of axon and RGCs. CMCS has been previously used as an anti-apoptotic and anti-oxidant agent. Objective The current study aimed to explore the protective impact of CMCS against H2O2-induced injury in glaucoma in vitro. Methods The relative expression of lncRNA THOR and the protein expression of IGF2BP1 in H2O2-induced RGC-5 cells were detected by RT-PCR and western blot methods respectively. The cell viability was measured using MTT assay while apoptosis rate was measured by fow cytometry. Moreover, ROS level was measured using ROS assay kit. Furthermore, the relations between THOR and IGF2BP1 were determined by using RNA pull-down. Results The expression of THOR was reduced in H2O2-induced RGCs. Also, RGCs viability was inhibited while the level of ROS and cell apoptosis were enhanced. CMCS treatment considerably enhanced the expression of THOR and IGF2BP1 protein and cell viability but reduced ROS level and cell apoptosis. Moreover, IGF2BP1 protein was positively regulated by lncRNA THOR. CMCS protected the RGCs from oxidative stress via regulating lncRNA THOR/IGF2BP1. Conclusion CMCS enhanced the cell viability and reduced the cell apoptosis and ROS level and protected RGCs from oxidative stress via lncRNATHOR/IGF2BP1 pathway, potentially suggesting a new therapeutic strategy for the treatment of glaucoma.
