        淸-朝鮮時期漢,滿,韓文字對音之互通 -以≪漢淸文鑑≫滿文的韓文表記法爲例

        ( Shao Lei ) 한국중국언어학회 2015 중국언어연구 Vol.0 No.61

        In Qing/Joseon Dynasty, there were some Cheong-hak-seo(청學書,Manchuria literature) written in both Korean and Manchu Script. The most important characteristic of Korean language``s materials hold Sa-yeok-weon (司譯院, the department of translation in Joseon & Goryeo Dynasty) and Yeok-hak-seo (譯學書, the literatures of translation) is considered as the foreign notational system. Not only the phonetic value written in Korean alphabet is different from each Yeok-hak-seo, but also the notational system. The most typical representative of it is "han-cheong-mun-gam (漢청文鑒)".There are some characteristics of notational system written in Manchu Script for Cheong-hak-seo: the notational system may be different according to the references. When we have to indicate a language by another language``s writing system, it could be classified into transliteration and transcription. It depends on how much they put emphasis on the shape of represented characters. Transliteration can be divided into two kinds: emphasis on pronunciation or neglect of pronunciation. however, transcription only puts emphasis on the pronunciation and ignores the shape.The goal of our research is to conclude the characteristics of Korean notation system of "han-cheong-mun-gam", as the representative of the Yeok-hak-seo, in Joseon Dynasty and introduce the unusual Korean notation system and diacritic marks. Based on the standard of transliteration and transcription, we can discover the core emphasis of "han-cheong-mun-gam". We also discuss Manchu language in two writing system: Manchu Script and Chinese characters in order to find out the characteristics of Manchu notational system and Korean notational system.

        Macrophage migration inhibitory factor mediates peripheral nerve injury-induced hypersensitivity by curbing dopaminergic descending inhibition

        Xian Wang,Shaolei Ma,Haibo Wu,Xiaofeng Shen,Shiqin Xu,Xirong Guo,Maria L Bolick,Shizheng Wu,Fuzhou Wang 생화학분자생물학회 2018 Experimental and molecular medicine Vol.50 No.-

        Our previous works disclosed the contributing role of macrophage migration inhibitory factor (MIF) and dopaminergic inhibition by lysine dimethyltransferase G9a/Glp complex in peripheral nerve injury-induced hypersensitivity. We herein propose that the proinflammatory cytokine MIF participates in the regulation of neuropathic hypersensitivity by interacting with and suppressing the descending dopaminergic system. The lumbar spinal cord (L-SC) and ventral tegmental area (VTA) are two major locations with significant upregulation of MIF after chronic constriction injury (CCI) of the sciatic nerve, and they display time-dependent changes, along with a behavioral trajectory. Correspondingly, dopamine (DA) content shows the reverse characteristic change to MIF with a time-dependent curve in post-surgical behavior. The levels of both MIF and DA are reversed by the MIF tautomerase inhibitor ISO-1, and a negative relationship exists between MIF and DA. The reversed role of ISO-1 also affects tyrosine hydroxylase expression. Furthermore, CCI induces Th promoter CpG site methylation in the L-SC and VTA areas, and this effect could be abated by ISO-1 administration. G9a/SUV39H1 and H3K9me2/H3K9me3 enrichment within the Th promoter region following CCI in the L-SC and VTA was also decreased by ISO-1. In cultured dopaminergic neurons, rMIF enhanced the recruitment of G9a and SUV39H1, followed by an increase in H3K9me2/H3K9me3. These molecular changes correspondingly exhibited alterations in Th promoter CpG site methylation and pain behaviors. In summary, MIF functions as a braking factor in curbing dopaminergic descending inhibition in peripheral nerve injury-induced hypersensitivity by mediating Th gene methylation through G9a/SUV39H1-associated H3K9 methylation.

      • Analysis of the Operating Principle and Parameter Design for the Modular Multilevel DC/DC Converter

        Binbin Li,Shaolei Shi,Yibo Zhang,Rongfeng Yang,Gaolin Wang,Dianguo Xu 전력전자학회 2015 ICPE(ISPE)논문집 Vol.2015 No.6

        The modular multilevel converter (MMC) has become more and more attractive in the field of high-voltage high-power dc/ac power conversions. In the very recent years, the dc/dc modular multilevel converter is proposed intended for high-voltage dc/dc applications, such as the solid-state transformers and future dc-grid networks, which is extended from the traditional MMC. However, it remains unknown how to optimize the operation of this dc/dc modular multilevel converter and how to dimension the parameters of the elements in it. In this paper, a detailed analysis is performed to indentify the operating principle of the dc/dc modular multilevel converter. Using these analyses, the selection rules and parameter design method of the components are given to maximize the utilization ratio, improve the power density, and increase efficiency. Finally, the validity and effectiveness of this paper are verified by simulation results.

        Proteomics Analysis of Rice Proteins Up-regulated in Response to Bacterial Leaf Streak Disease

        Dongxiao Li,Liangjiang Wang,Shaolei Teng,Guoguang Zhang,Lijia Guo,Qian Mao,Wei Wang,Min Li,Liang Chen 한국식물학회 2012 Journal of Plant Biology Vol.55 No.4

        Bacterial leaf streak (BLS), caused by the pathogen Xanthomonas campestris pv. Oryzicola, is a major rice disease in tropical and subtropical regions of Asia. Rice proteins responsive to BLS are still not well characterized. We took a proteomics approach to identify the proteins that are up-regulated in rice leaves after infection. Approximately 1,500 protein spots were detected on each 2-D gel after silver-staining; those with increased protein levels were selected for MALDI-TOF-MS analysis. We identified 32 up-regulated proteins that might be involved in disease resistance signal transduction, pathogenesis, and regulation of cell metabolism. By using publicly available microarray data, we determined the mRNA transcripts of 23 proteins expressed in the leaves. Seven genes were analyzed by northern blots, which demonstrated that transcript levels were increased after bacterial infection. Our findings help elucidate the molecular mechanisms underlying BLS and provide a solid foundation for further research on the functions of relevant genes.

      • Bidirectional Energy Trading and Residential Load Scheduling with Electric Vehicles in the Smart Grid

        Byung-Gook Kim,Shaolei Ren,van der Schaar, M.,Jang-Won Lee IEEE 2013 IEEE journal on selected areas in communications Vol.31 No.7

        <P>Electric vehicles (EVs) will play an important role in the future smart grid because of their capabilities of storing electrical energy in their batteries during off-peak hours and supplying the stored energy to the power grid during peak hours. In this paper, we consider a power system with an aggregator and multiple customers with EVs and propose novel electricity load scheduling algorithms which, unlike previous works, jointly consider the load scheduling for appliances and the energy trading using EVs. Specifically, we allow customers to determine how much energy to purchase from or to sell to the aggregator while taking into consideration the load demands of their residential appliances and the associated electricity bill. We propose two different approaches: a collaborative and a non-collaborative approach. In the collaborative approach, we develop an optimal distributed load scheduling algorithm that maximizes the social welfare of the power system. In the non-collaborative approach, we model the energy scheduling problem as a non-cooperative game among self-interested customers, where each customer determines its own load scheduling and energy trading to maximize its own profit. In order to resolve the unfairness between heavy and light customers in the non-collaborative approach, we propose a tiered billing scheme that can control the electricity rates for customers according to their different energy consumption levels. In both approaches, we also consider the uncertainty in the load demands, with which customers' actual energy consumption may vary from the scheduled energy consumption. To study the impact of the uncertainty, we use the worst-case-uncertainty approach and develop distributed load scheduling algorithms that provide the guaranteed minimum performances in uncertain environments. Subsequently, we show when energy trading leads to an increase in the social welfare and we determine what are the customers' incentives to participate in the energy trading in various usage scenarios including practical environments with uncertain load demands.</P>

      • Incentive Mechanisms for Economic and Emergency Demand Responses of Colocation Datacenters

        Tran, Nguyen H.,Do, Cuong T.,Shaolei Ren,Zhu Han,Choong Seon Hong IEEE 2015 IEEE journal on selected areas in communications Vol.33 No.12

        <P>Demand response programs have been considered critical for power grid reliability and efficiency. Especially, the demand response of datacenters has recently received encouraging efforts due to huge demands and flexible power control knobs of datacenters. However, most current efforts focus on owner-operated datacenters, omitting another critical segment of datacenter business: multitenant colocation. In colocation datacenters, while there exist multiple tenants who manage their own servers, the colocation operator only provides facilities such as cooling, reliable power, and network connectivity. Therefore, colocation has a unique feature that challenges any attempts to design a demand response program: uncoordinated power management among tenants. To tackle this challenge, two incentive mechanisms are proposed to coordinate tenant power consumption for demand response under two different scenarios. First, in the case of economic demand response where the operator can adjust an elastic energy reduction target, we show that there is an interaction between the operator and tenant strategies, where each side maximizes its own benefit. Hence, we apply a two-stage Stackelberg game to analyze this scenario and derive this game's equilibria. However, computing these equilibria can be intractable with exhaustive search; therefore, we propose an algorithm to find the Stackelberg equilibria with linear complexity. Second, in the case of emergency demand response where a fixed energy reduction target must be fulfilled, we devise two incentive schemes with the distributed algorithms that can achieve the same optimal social cost. While the first algorithm is based on the dual-decomposition method that is suitable for nonstrategic tenants, the second one is designed for strategic tenants to achieve a unique Nash equilibrium of a bidding game. Finally, trace-based simulations are also provided to illustrate the efficacy of our proposed incentive schemes.</P>

      • Reward-to-Reduce: An Incentive Mechanism for Economic Demand Response of Colocation Datacenters

        Tran, Nguyen H.,Oo, Thant Zin,Ren, Shaolei,Han, Zhu,Huh, Eui-Nam,Hong, Choong Seon IEEE 2016 IEEE journal on selected areas in communications Vol.34 No.12

        <P>Even though demand response of datacenters has attracted many studies, there are very limited attempts on an important segment: colocation datacenters. Unlike large-scale (Google-type) datacenters, the colocation operator lacks control over its tenant servers, which entails a special interest in a design of incentive mechanisms, such that the operator can coordinate tenants to reduce the power usage for demand response. However, most previous studies ignore the role of the demand response provider (DRP), who uses pricing signals as a guide for customer response and as a compensation for their cutting electricity usage. To address this oversight, we propose an incentive mechanism Reward-to-Reduce for colocation's economic demand response, which shows an interaction between the DRP compensation to the colocation operator, and the colocation operator reward to tenants. Observing that this interaction contains strategic behaviors, we first formulate a two-stage Stackelberg game, where we show a unique competitive equilibrium of the operator strategy in the second stage, and a nonconvex problem of finding the optimal DRP compensation price in the first stage. We next analyze the second-stage equilibrium using an exact analysis and design an algorithm that can efficiently search the first-stage optimal DRP price with a reduced search space. Since the exact analysis can be impractical due to required tenants' private information, we also propose an approximate approach with limited tenant information. Extensive case studies show that the approximate approach can have the same performance as the exact analysis in a wide array of case studies and the optimal DRP price can be determined effectively, with which the corresponding DRP individual cost is compared with the social cost.</P>

      • Root hair‐specific expansins modulate root hair elongation in rice

        ZhiMing, Yu,Bo, Kang,XiaoWei, He,ShaoLei, Lv,YouHuang, Bai,WoNa, Ding,Ming, Chen,Hyung‐,Taeg, Cho,Ping, Wu Blackwell Publishing Ltd 2011 The Plant journal Vol.66 No.5

        <P><B>Summary</B></P><P>Root hair growth requires intensive cell‐wall modification. This study demonstrates that root hair‐specific expansin As, a sub‐clade of the cell wall‐loosening expansin proteins, are required for root hair elongation in rice (<I>Oryza sativa</I> L.). We identified a gene encoding <I>EXPA17</I> (<I>OsEXPA17</I>) from a rice mutant with short root hairs. Promoter::reporter transgenic lines exhibited exclusive <I>OsEXPA17</I> expression in root hair cells. The OsEXPA17 mutant protein (OsexpA17) contained a point mutation, causing a change in the amino acid sequence (Gly104→Arg). This amino acid alteration is predicted to disrupt a highly conserved disulfide bond in the mutant. Suppression of <I>OsEXPA17</I> by RNA interference further confirmed requirement for the gene in root hair elongation. Complementation of the <I>OsEXPA17</I> mutant with other root hair EXPAs (OsEXPA30 and Arabidopsis EXPA7) can restore root hair elongation, indicating functional conservation of these root hair EXPAs in monocots and dicots. These results demonstrate that members of the root hair EXPA sub‐clade play a crucial role in root hair cell elongation in Graminaceae.</P>

        Chlorogenic acid accumulation and related gene expression in peach fruit

        Yan Juan,Su Ziwen,Guo Shaolei,Zhang Minghao,Zhang Binbin,Cai Zhixiang,Shen Zhijun,Ma Ruijuan,Yu Mingliang 한국원예학회 2022 Horticulture, Environment, and Biotechnology Vol.63 No.3

        To reveal the molecular mechanism in the accumulation of chlorogenic acids (CGAs) in peach (Prunus persica) fruit during growth and development, CGA contents in the flesh of the three peach cultivars ‘Ruiguang 18’, ‘Heiyoutao’, and ‘Beijingyixianhong’ were determined. The expression levels of CGA metabolism-related genes were analyzed based on transcriptome data (RNA-seq). These candidate genes were then screened and real-time fluorescent quantitative PCR (qRT-PCR) was performed to verify their expression. The results showed that the content of total CGAs, 5-O-caffeoylquinic acid and 3-O-caffeoylquinic acid, in the flesh of ‘Ruiguang 18’ exhibited a decreasing trend during fruit development, and there was a great drop at maturity stage (P < 0.05). The three contents in ‘Heiyoutao’ increased first at stage S2 (P < 0.05) and then decreased significantly (P < 0.05). In ‘Beijingyixianhong’, they stayed stable in the early stages, then total CGAs and 3-O-caffeoylquinic acid decreased significantly at the maturity stage (P < 0.05). RNA-seq transcriptome data analysis and qRT-PCR expression analysis showed that the accumulation of CGAs in fruit flesh was mainly affected by the expression of Prupe.3G100800 (PpHCT) and Prupe.3G107300 (Pp4CL), and their expression levels were highly consistent with total CGA content. Thus, we concluded that Prupe.3G100800 (PpHCT) and Prupe.3G107300 (Pp4CL) are the key genes for CGAs synthesis in peach flesh.
