        Identification and expression analysis of ERECTA family genes in grape (Vitis vinifera L.)

        Min Liu,Wanping Li,Zhuo Min,Xianghan Cheng,Yulin Fang 한국유전학회 2019 Genes & Genomics Vol.41 No.6

        Background ERECTA family (ERf) genes are found in many dicots and monocots, and play important roles in plant developmental processes and stress responses. However, there is little known on ERf genes in grape (Vitis vinifera L.). Objectives The primary objective of this study was to identify the ERf genes in grape, and to analyze their expression profiles in different organs, during development, and in response to hormone treatments and abiotic/biotic stresses. Methods ERf protein sequences of dicots were aligned in the grape genome (V. vinifera cv. Pinot Noir, PN40024, 12X) with Blast server. The locus tags obtained were inputted in NCBI to retrieve corresponding nucleotide and protein accession numbers. The subcellular localization experiment was performed by the transient expression of VvERECTA-GFP and VvERL2-GFP in mesophyll protoplasts of Arabidopsis. The expression levels of ERf genes in grape leaves were detected by qRT-PCR after hormone treatments and abiotic/biotic stresses. Results We first identified the ERf genes in the grape genome, including VvERECTA and VvERL2. Their cDNA full-length sequences were obtained with the accession numbers MG601756 and MG601757. The result of subcellular localization indicated that the fusion proteins of VvERECTA and VvERL2 were localized in the plasma membrane. There were four conserved domains identified in VvERECTA and VvERL2, including a LRRNT-2, a LRR, a transmembrane and a protein kinase domain. The grape ERf genes expressed highly in young aboveground organs. As grape leaves or berries becoming mature, VvERECTA expressed in a declining trend. The transcript abundance of VvERL2 decreased during leaves development, but showed no significant differences during berries development. The hormone treatments of ABA, SA, MeJA and BR could induce the expression of VvERECTA and VvERL2. The treatments of heat, drought, downy and powdery mildew significantly increased the expression levels of the grape ERf genes. Conclusion The grape ERECTA gene family might play crucial roles in response to abiotic and biotic stresses. We provide the first description of the grape ERf genes and the most comprehensive analysis of their expressions in different biological processes.

        Modelling of Acoustic Waves Propagating in Nesting Fibonacci Super-Lattice Phononic Crystal

        Min Zhao,Hai-Feng Qi,Jia-Hui Xu,Ya-Zhuo Xie,Xing-Gan Zhang,Jian Gao 대한금속·재료학회 2014 METALS AND MATERIALS International Vol.20 No.4

        Herein, we report construction of one kind of nesting-Fibonacci-super-lattice phononic crystal, in whichthe super-lattice cell is a well-defined Fibonacci generation sequence. We present a comparative study onband-gap structures of acoustic waves propagating in one-dimensional, nesting Fibonacci-periodic structureand simple-periodic structure. We find that there are more band gaps in nesting Fibonacci super-latticemodels, and that they present behavior different from the split-up of band gaps with different generationnumbers. With the increase of generation number, more band gaps split and occur. Additionally, whengeneration number becomes larger, Bragg scattering becomes more significant: the characteristic curvesbecome flatter and band gaps become wider. Furthermore, we study the effect of various parameters suchas density, thickness and defects on band-gap structures. Our work is significant both for understandingthe intrinsic physical properties of nesting Fibonacci sequences and for providing flexible choices to meetreal engineering requirements.

      • An Optimized Motion Estimation Algorithm and Application in the FRUC System

        Min-Jun Deng,Ping Gan,Zhuo Chen,Xiao-Qing Shen,Dong-Lian Li,Ming-Yan Yu,Yu Zhang,Cai -Lan Zeng,He Huang 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.8

        Based on the optimized three-step search algorithm. Combining threshold judgment as well as local full search, a more efficient motion estimation algorithm is proposed. The algorithm not only inherited the traditional three-step algorithm’s quick speed but also kept the advantages of a relatively small amount of calculation, besides it can avoid the local optimum problem in the three-step search algorithm (TSS). In addition, the algorithm combined with the threshold judgment and local full search algorithm, so it also maintains satisfactory visual quality. Comparing the algorithm with TSS and local full search algorithm (LFS). The algorithm has great performance in search points and peak signal-to-noise ratio. Experimental results show that compared with LFS, search points drop by 34.61% ~ 54.47% .While compared with the TSS, the search points only rise by 6.15% ~ 12.21%. The average PSNR of proposed Algorithm is 0.24dB higher than LFS and 3.30dB higher than TSS.

        Suspension Footbridge Form-Finding with Laplacian Smoothing Algorithm

        Zhuo-ju Huang,Jie-min Ding,Sheng-yi Xiang 한국강구조학회 2020 International Journal of Steel Structures Vol.20 No.6

        In this paper, Laplacian smoothing, which is an algorithm originally used to smooth polygon meshes in computer graphics (CG), is applied to solve a structural form-fi nding problem with the proof that the result of such algorithm is equivalent to force density method. Such CG algorithm is used on the design of a new-built suspension footbridge in Shaoxing, China and the algorithm works well. Since Laplacian smoothing is a pure geometric algorithm without any mechanical concept, the algorithm shows the inner relationship between force and shape, more structural applicable CG algorithms are expected to be found in the future.

Purpose : This study aimed to compare the face width and pupillary distance between Korean and Chinese adults and to compare the frame size and design shape of the currently worn spectacle frame. Methods : Data were collected in a prospective manner for 100 adult men and women in their 20s and 30s, and 100 adult men and women in their 20s and 30s, respectively, who visited the Optometry office in Jilin Province China, Gyeongsan Korea. The face width was measured using a mobile application and PD meter was used to for far and near PD. The frame size was measured according to the Boxing system, and the frames design was e classified into shapes (round, oval, rectangle), rim shapes (full rim, half rim, no rim) and materials (plastic, metal, and combinations). For the analysis, one-way ANOVA for comparison among groups, Chi-Square analysis for frequency, Z-test for ration difference. Results : Range of face width was 149.73±6.28 (Chinese woman) ~ 152.29±14.71 <단위 앞 mm (Korean male), but there was no statistical significance between groups (p=0.147). There was statistical significance between groups in both far and near PD (p<0.001). There were statistical significance between groups for all of frame measurement (eye size, bridge size, vertical height) (p<0.001). There was statistical significance in all frame design except for the combination material (p=0.790). Conclusion : This study showed that there was no face width difference between Korean and Chinese adult, but there was a difference in PD measurement. Frame size from Korean and Chinese wearers were clearly different showing that more Korean worn round shape of frame while rectangle shape was preferred by Chinese. Therefore when Chinese customer visit optometric practice in Korea, practitioner should be able to understand the different preference of frame design. When designing frame for overseas market, it will be necessary to consider face shape and local preference.

      • A QoE Evaluation Method for RT-HDMV Based on Multipath Relay Service

        Yu-Zhuo Zhan,Wei-Min Lei,Yun-Chong Guan 한국통신학회 2019 한국통신학회 학술대회논문집 Vol.2019 No.1

        In the paper, a multipath relay service based on QoE (Quality of Experience) evaluation method is proposed for RT-HDMV (Real-Time High Definition Medical Video). The method eliminates several of the limitations in the existing methods for the conventional single-path transmission. It can fully utilize the finite network resources and transmission bandwidth to meet the users’ demands of RT-HDMV to get the better score of QoE. We use a three-stage framework to evaluate the QoE: construct the multipath relay transmission for RT-HDMV, design the load distribution strategy by the mapping between QoS (Quality of Service) and QoE and coupling the multipath scene, and redefine the rule of QoE evaluation. The experiments show that our framework can provide better QoE guarantees for RT-HDMV than existing methods in traditional single-channel transmission scenarios.

        Water temperature and salinity tolerance of embryos and spat of the mussel, Musculista senhousia

        Liang, Zhuo Liang,Kim, Young-Hun,Zhang, Zhi Fang,Lim, Sang-Min,Kang, Kyoung-Ho The Malacological Society of Korea 2009 The Korean Journal of Malacology Vol.25 No.3

        The effects of water temperature and salinity on embryonic development and spat survival of mussel Musculista senhousia were investigated. Embryos were incubated in water ranging from 0 to $35^{\circ}C$ and with salinity from 5‰ to 40‰. Mussel spat were tested in water from 0 to $40^{\circ}C$ and with salinity from 0‰ to 100‰. The optimal conditions for mussel embryos were $20-25^{\circ}C$ and salinity from 25‰ to 35‰, based on Within this temperature range, higher temperatures correponded to a shorter duration of the embryonic period. Optimisation of mussel spat survival was at $25-35^{\circ}C$ and salinity from 30‰ to 40‰; both values are higher than those for embryo, which hinted M. senhousia embryos are more vulnerable than spat. Temperatures below $15^{\circ}C$ were lethal for embryos, making temperature a feasible method with which to control the large population of M. senhousia in ark-shell farm during its spawning period.
