Although a large number of AroA enzymes (EPSPS: 5-enopyruvylshikimate-3-phosphate synthase) have been identified, cloned, and tested for glyphosate resistance, only two AroA variants, derived from Agrobacterium tumefaciens strain CP4 and Zea mays, have been utilized to produce the commercial glyphosate-resistant crops. Here, we have used a PCR-based twostep DNA synthesis method to synthesize an aroA gene (aroAA. metalliredigens) from Alkaliphilus metalliredigens, encoding a new EPSPS. Furthermore, transgenic Arabidopsis with the new aroAA. metalliredigens gene was obtained to confirm the potential of the novel aroA gene in developing glyphosate-resistant crops.

Sheng Liu,Bowen Xing,Bing Li,Mingming Gu 대한조선학회 2014 International Journal of Naval Architecture and Oc Vol.6 No.3
Ship Information Systems (SISs) have been one of the main research focuses in ship design and become a multidisciplinary area. With these growing research trends, it is important to consolidate the latest knowledge and in-formation to keep up with the research needs. In this paper, the SIS and its different forms are introduced and discussed. The beginning of this paper discusses the history and evolution of SIS. The next part of this paper focuses on different fields and research areas such as networking technology, information fusion, information decision, message display, ship control in real-time SISs. A Semi-Physical Simulation Platform (SPSIM) designed for SIS research and its running effect through a new Fuzzy-PID fusion algorithm are introduced in this paper then. A brief literature survey and po-ssible future direction concerning each topic is included.

Xing-Wei Ding,Fei Huang,Sheng Li,Jianhua Zhang,Xue-Yin Jiang,Zhi-Lin Zhang 대한금속·재료학회 2017 ELECTRONIC MATERIALS LETTERS Vol.13 No.1
This work reports an efficient route for enhancing the performanceof amorphous InGaZnO (a-IGZO) thin film transistors (TFT). Themobility was greatly improved by about 38% by means of O2plasma treatment. Temperature-stress was carried out to investigatethe stability and extract the parameters related to activation energy(Ea) and density-of-states (DOS). The DOS was calculated on thebasis of the experimentally obtained Ea, which can explain theexperimental observation. A lower activation energy (Ea, ~0.72 eV)and a smaller DOS were obtained in the O2 plasma treatment TFTbased on the temperature-dependent transfer curves. The resultsshowed that temperature stability and electrical propertiesenhancements in a-IGZO thin film transistors were attributed to thesmaller DOS.

The high-quality green-emitting CdS0 . 5Se0 .5/8Zn1 − x Cd x S/2ZnS QDs with “8” and “2” monolayers (ML) of corresponding shell were first synthesized by “thermal-cycling coupled single precursor” (TC-SP) approach. The component-gradient Zn1− x Cd x S interlayer played a key role in the growth of thick shell by gradually buffering the large lattice mismatch (~9%) between the CdS0 . 5Se0 .5 core and ZnS shell. Moreover, the Zn1− x Cd x S gradient interlayer as well as ZnS outshell increased the potential barrier to prevent excitons from being trapped by surface defects. The photoluminescence quantum yields of the as-synthesized CdS0 . 5Se0 .5/8Zn1 − x Cd x S/2ZnS core/shell QDs can reach to 70% in organic media and still maintain 60% after aqueous phase transfer. The green-emitting CdS0 . 5Se0 .5/8Zn1 − x Cd x S/2ZnS core/shell QDs may be good candidates for applications of biomedical and photoelectric field.
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.
Improvement of the Multiple Image Encryption Capacity Using QR Code as a Data Container
Xing Bai,Jianping Hu,Sheng Yuan,Jinchao Wang,Jing Wang,Xin Zhou 한국광학회 2020 Current Optics and Photonics Vol.4 No.4
An image encryption scheme based on the quick response (QR) code as a data container has aroused wide interest due to the lossless recovery of the decrypted image. In this paper, we apply this method to multi-image encryption. However, since the decrypted image is affected by crosstalk noise, the number of multi-image encryptions is severely limited. To solve this problem, we analyzed the performance of QR code as a data container, and processed the decrypted QR code using the proposed method, so that the number of multi-image encryptions is effectively increased. Finally, we implemented a large image (256 × 256) encryption and decryption.
Integration of Design of Experiments into Quality Function Deployment
Sheng, Jing,He, Zhen,Shi, Liang Xing 한국품질경영학회 2002 The Asian Journal on Quality Vol.3 No.1
Quality Function Deployment (QFD) is a useful planing process in new product development. It achieves the maximum custom satisfaction through translating Voice of the Customer (VOC) into voice of the engineer in the House of Quality (HOQ), and ensures the customer focus from house to house translation. In QFD, the relationship matrix and correlation matrix are important parts, which will influence the final priorities of the technical response. According to the traditional methods, these matrices are determined by the people's experience and filled with ordinal numbers. It would inevitably result in inaccuracy and curtness. Design of Experiments (DOE) is employed to determine the effect of variables on the process. In this paper, the author puts forward the idea of integrating DOE into the process of QFD. This integration helps to produce scientific decision and robust product design. A framework on QFD/DOE is presented and explanations are also made.

<P>A novel actinomycete, designated strain KLBMP 1262(T), was isolated from a coastal plant Dendranthema indicum (Linn.) Des Moul collected from the coastal region of Nantong, Jiangsu Province, in east China and was studied in detail for its taxonomic position. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain KLBMP 1262(T) is a member of the genus Amycolatopsis. The 16S rRNA gene sequence similarity indicated that strain KLBMP 1262(T) is most closely related to Amycolatopsis sulphurea DSM 46092(T) (97.96 %), Amycolatopsis ultiminotia RP-AC36(T) (97.50 %) and Amycolatopsis jejuensis N7-3(T) (97.44 %); similarity to other type strains of the genus Amycolatopsis was less than 97.0 %. The organism was determined to have chemical and morphological features consistent with its classification in the genus Amycolatopsis such as meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall peptidoglycan and arabinose and galactose as the diagnostic sugars. The predominant menaquinone was determined to be MK-9 (H(4)). The polar lipids detected were phosphatidylmethylethanolamine, phosphatidylethanolamine, an unknown aminophospholipid, two unknown glycolipids and several unknown lipids. The major fatty acids were found to be C(16:0), iso-C(16:0) and iso-C(15:0). DNA-DNA relatedness data, together with phenotypic differences, clearly distinguished the isolate from its closest relatives. On the basis of these phenotypic and genotypic data, the isolate is considered to represent a novel species, for which the name A. jiangsuensis sp. nov. is proposed. The type strain is KLBMP 1262(T) (=KCTC 19885 (T) = NBRC 108679(T)).</P>
