Zhi‐Jun Zhou,Xiao-Yan KOU,Lei-YangQIAN,Jing LIU 한국곤충학회 2016 Entomological Research Vol.46 No.3

The Chinese bush cricket, Gampsocleis gratiosa, has a long history as a pet in China. To date, the sequencing of its whole genome is unavailable as a non‐model organism. Transcriptomic information is also scarce for this species. The G. gratiosa transcriptome was sequenced using Illumina HiSeq 2000 paired‐end sequencing technology. In total 52 million clean reads with an average length of 90 bp were generated, which produced 74,821 unigenes with a mean length of 580 bp and an N50 length of 759 bp. In total 29,674 (39.66%) unigenes were successfully annotated against the NR, NT, Swiss‐Prot, Gene Ontology (GO), Clusters of Orthologous Groups of proteins (COGs) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. Further functionally classified of unigenes against GO, COGs and KEGG found that a total of 11,935 (19.95%) unigenes were categorized into 61 GO terms, 19,576 unigenes were clustered into 25 COG functional categories and 17,971 unigenes were assigned to 258 KEGG pathways. In addition, 2093 microsatellite loci were identified, of which 591 loci had flanking sequences suitable for polymerase chain reaction (PCR) primer design. The transcriptome profile of G. gratiosa contributed to the accumulation of orthopteran genomic data, and the microsatellite loci provided useful tools for future studies of this and other closely related Gampsocleis species.

( Jun Zhi He ) 국민대학교 중국지식네트워크 2012 중국지식네트워크 Vol.2 No.-

先前對中國地方人大監督“兩院”工作的硏究, 主要關註的是主要問題和整體變化趨勢。以東部某市的13個區縣人大常委會的自塡式問卷爲樣本, 本文主要考察了同壹區域內部的各區縣人大常委會在監督“兩院”工作所體現出的差異性及其原因。硏究發現, 多元化與規範化是當前地方人大常委會監督“兩院”工作的兩種基本策略。在那些常委會組成人員專職化程度較高·內務司法工作委員會的成員專業化程度較高的地方人大常委會, 更傾向於采用多樣化策略;而那些常委會組成人員的專職化程度較低·內務司法工作委員會的成員專業程度較低的地方人大常委會, 則更傾向於采用規範化策略。 In China’s studies, Previous studies on the supervision works from the local People’s Congresses to judicial organs mainly focused on the mail problems and whole changes. Based on the self-administration questionnaires from 13 county-level People’s Congress standing committees in a east municipality, this paper investigates the different strategies of local People’s Congress standing committees in the same municipality. The paper shows that diversification and normalization are two basic supervision strategies of the local People’s Congress standing committees. Those who have more full time members in the standing committees and more specialized members in the interior affairs and judicial working committees tend to adopt a diversification strategy; whereas those who have less full time members and specialized members tend to adopt a normalization strategy.

Cationic amino acid transporter $b^{0,+}AT$ (HGMW-approved gene symbol SLC7A9, solute carrier family 7, member 9) plays a crucial role in amino acid nutrition. In the present study, we describe the cloning and sequencing of porcine $b^{0,+}AT$. Based on the sequence of porcine $b^{0,+}AT$ deposited in the NCBI (National Center for Biotechnological Information), we identified a putative porcine homologue. Using rapid amplification of cDNA ends (RACE), the full-length cDNA encoding porcine $b^{0,+}AT$ was isolated. The porcine $b^{0,+}AT$ cDNA was 1,680 bp long, encoding a 487 amino acid trans-membrane protein. The predicted amino acid sequence was found to have 88.9% and 87.1% identity with human and mouse $b^{0,+}AT$, respectively. Real-time RT-PCR indicated porcine $b^{0,+}AT$ transcripts expressed in heart, kidney, muscle and small intestine. The small intestine had the highest $b^{0,+}AT$ mRNA abundance while the muscle had the lowest (p<0.05). Along the longitudinal axis, the ileum had the highest $b^{0,+}AT$ mRNA abundance while the colon had the lowest (p<0.05). The $b^{0,+}AT$ mRNA level was highest on day 7 and 90 in the duodenum (p<0.05). It increased from day 1 to day 26 in the jejunum (p>0.05) and had the highest abundance on day 60 (p<0.05). There was, however, no difference between day 1, 7, 26, 30, 90 and 150 (p>0.05). The strongest $b^{0,+}AT$ expression appeared on day 7 in the ileum before weaning, and then decreased till day 30 but rose gradually again from day 60 to 150 (p<0.05).

In this study, we cloned, sequenced and characterized porcine y+L Amino Acid Transporter-1 (y+LAT1). By screening a translated EST database with the protein sequence of the human $y^{+}$LAT1 and by using rapid amplification of cDNA ends (RACE), the full-length cDNA encoding porcine $y^{+}$LAT1 was isolated from porcine intestine RNA. It was 2,111 bp long, encoding a 511 amino acid trans-membrane glycoprotein composed of 12 transmembrane domains. The predicted amino acid sequence was found to be 91%, 90%, 87% and 87% identical to those of cattle, human, mouse and rat $y^{+}$LAT1 respectively. Real-time RT-PCR results indicated that the small intestine had the highest $y^{+}$LAT1 mRNA abundance and the lung had the lowest $y^{+}$LAT1 mRNA abundance. Baby hamster kidney (BHK) cells transfected with green fluorescent protein (GFP) tagged porcine $y^{+}$LAT1 cDNA indicated that the cellular localization of the gene product in BHK was on the plasma membrane.

Simultaneous Information and Power Transfer for Multi-antenna Primary-Secondary Cooperation in Cognitive Radio Networks

Zhi Hui Liu,Wen Jun Xu,Sheng Yu Li,Cheng Zhi Long,Jia Ru Lin 한국전자통신연구원 2016 ETRI Journal Vol.38 No.5

In this paper, cognitive radio and simultaneous wireless information and power transfer (SWIPT) are effectively combined to design a spectrum-efficient and energy-efficient transmission paradigm. Specifically, a novel SWIPT-based primary-secondary cooperation model is proposed to increase the transmission rate of energy/spectrum constrained users. In the proposed model, a multi-antenna secondary user conducts simultaneous energy harvesting and information forwarding by means of power splitting (PS), and tries to maximize its own transmission rate under the premise of successfully assisting the data delivery of the primary user. After the problem formulation, joint power splitting and beamforming optimization algorithms for decode-and-forward and amplify-and-forward modes are presented, in which we obtain the optimal PS factor and beamforming vectors using a golden search method and dual methods. Simulation results show that the proposed SWIPTbased primary-secondary cooperation schemes can obtain a much higher level of performance than that of non-SWIPT cooperation and non-cooperation schemes.

A topological optimization method for flexible multi-body dynamic system using epsilon algorithm

Zhi-Jun Yang,Xin Chen,Robert Kelly 국제구조공학회 2011 Structural Engineering and Mechanics, An Int'l Jou Vol.37 No.5

In a flexible multi-body dynamic system the typical topological optimization method for structures cannot be directly applied, as the stiffness varies with position. In this paper, the topological optimization of the flexible multi-body dynamic system is converted into structural optimization using the equivalent static load method. First, the actual boundary conditions of the control system and the approximate stiffness curve of the mechanism are obtained from a flexible multi-body dynamical simulation. Second, the finite element models are built using the absolute nodal coordination for different positions according to the stiffness curve. For efficiency, the static reanalysis method is utilized to solve these finite element equilibrium equations. Specifically, the finite element equilibrium equations of key points in the stiffness curve are fully solved as the initia solution, and the following equilibrium equations are solved using a reanalysis method with an error controlled epsilon algorithm. In order to identify the efficiency of the elements, a non-dimensional measurement is introduced. Finally, an improved evolutional structural optimization (ESO) method is used to solve the optimization problem. The presented method is applied to the optimal design of a die bonder. The numerical results show that the presented method is practical and efficient when optimizing the design of the mechanism.

Improved Conditional Differential Attacks on Round-Reduced Grain v1

( Jun-zhi Li ),( Jie Guan ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.9

Conditional differential attack against NFSR-based cryptosystems proposed by Knellwolf et al. in Asiacrypt 2010 has been widely used for analyzing round-reduced Grain v1. In this paper, we present improved conditional differential attacks on Grain v1 based on a factorization simplification method, which makes it possible to obtain the expressions of internal states in more rounds and analyze the expressions more precisely. Following a condition-imposing strategy that saves more IV bits, Sarkar’s distinguishing attack on Grain v1 of 106 rounds is improved to a key recovery attack. Moreover, we show new distinguishing attack and key recovery attack on Grain v1 of 107 rounds with lower complexity O(2³⁴) and appreciable theoretical success probability 93.7%. Most importantly, our attacks can practically recover key expressions with higher success probability than theoretical results.

( Jun-xian Xu ),( Yang Liu ),( Ming-yu Wen ),( Hee-jun Park ),( Jia-zhi Zhu ),( Yu-nan Liu ) 한국목재공학회 2021 목재공학 Vol.49 No.6

A novel flame retardant and antibacterial composite membrane coating for wood surfaces was prepared by adding POSS-based phosphorous nitrogen flame retardant (later referred to as NH₂-POSS) and silver nanoparticles (Ag NPs) to chitosan (CS). The effects of NH₂-POSS content (mass fractions of CS 0%, 0.5%, 1%, 3%, 5%, and 7%) on the structure and properties of the composite membrane coating on wood were investigated. The composite film was prepared by the method of blending and ducting. Contact angle, tensile property and antibacterial effects of the composite film were measured, and infrared spectroscopy was used. The results show that the addition of NH₂-POSS can not only improve the toughness of the membrane, but also the flame retardancy of the membrane, which improves the application of the membrane in wood products. However, with the addition of NH₂-POSS, the transparency of the composite membrane was weakened. The inhibitory effect of the composite membrane on the growth of Escherichia coli was enhanced with the increase in Ag NPs. This research provides a foundation for the application of functional wood.
