W. B. Yeats’s Influence on Mu Dan and Yuan Kejia, Two of the Nine Leaves Poets in China
Ze-yuan Hu 한국예이츠학회 2021 한국예이츠 저널 Vol.64 No.-
W. B. 예이츠의 시는 1920년대 이후 중국에 소개되었는데, 그는 아일랜 드의 대표적 시인이다. 그의 시는 중국의 시에 큰 영향을 끼치는데 특히 나인 리브스 파 시인들 중 무 단과 연 게이자에 대한 영향이 크다. 비교연구를 통해서, 본 논문은 무 단은 자신의 시 스타일 형성에 예이츠에게 영향을 받았으며, 연 게이자는 자신의 시이론을 형성하는데 많은 자양분을 흡수했다는 사실을 증명한다. W. B. Yeats is an important Irish poet whose poems have been introduced to China since 1920s and exerted great influence on Chinese poetry, especially on Mu Dan and Yuan Kejia, two of the Nine-Leaves Poets. Through a comparative study, the paper discovers that while forming his own poetic style Mu Dan got much inspiration from Yeats and that Yuan Kejia formed his poetic theory by taking nutrition from Yeats.
Implementation and benchmarking of the local weight window generation function for OpenMC
Hu Yuan,Yan Sha,Qiu Yuefeng 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.10
OpenMC is a community-driven open-source Monte Carlo neutron and photon transport simulation code. The Weight Window Mesh (WWM) function and an automatic Global Variance Reduction (GVR) method was recently developed and implemented in a developmental branch of OpenMC. This WWM function and GVR method broaden OpenMC's usage in general purposes deep penetration shielding calculations. However, the Local Variance Reduction (LVR) method, which suits the source-detector problem, is still missing in OpenMC. In this work, the Weight Window Generator (WWG) function has been developed and benchmarked for the same branch. This WWG function allows OpenMC to generate the WWM for the source-detector problem on its own. Single-material cases with varying shielding and sources were used to benchmark the WWG function and investigate how to set up the particle histories utilized in WWG-run and WWM-run. Results show that there is a maximum improvement of WWM generated by WWG. Based on the above results, instructions on determining the particle histories utilized in WWG-run and WWM-run for optimal computation efficiency are given and tested with a few multi-material cases. These benchmarks demonstrate the ability of the OpenMC WWG function and the above instructions for the source-detector problem. This developmental branch will be released and merged into the main distribution in the future

Campylobacter jejuni is a prevalent foodborne pathogen worldwide. Human infection by C. jejuni primarily arises from contaminated poultry meats. Genes expressed in vivo may play an important role in the pathogenicity of C. jejuni. We applied an immunoscreening method, in vivo-induced antigen technology (IVIAT), to identify in vivo-induced genes during human infection by C. jejuni. An inducible expression library of genomic proteins was constructed from sequenced C. jejuni NCTC 11168 and was then screened using adsorbed, pooled human sera obtained from clinical patients. We successfully identified 24 unique genes expressed in vivo. These genes were implicated in metabolism, molecular biosynthesis, genetic information processing, transport, and other processes. We selected six genes with different functions to compare their expression levels in vivo and in vitro using real-time RT-PCR. The results showed that the selected six genes were significantly upregulated in vivo but not in vitro. In short, these identified in vivo-induced genes may contribute to human infection of C. jejuni, some of which may be meaningful vaccine candidate antigens or diagnosis serologic markers for campylobacteriosis. IVIAT may present a significant and efficient method for understanding the pathogenicity mechanism of Campylobacter and for finding targets for its prevention and control.
Diverse chromosomal rearrangements induced by Ac/Ds at the OsRLG5 locus in regenerated rice plants
Yuan Hu Xuan,박순주,조준현,김태호,한창덕 한국식물학회 2015 Journal of Plant Biology Vol.58 No.5
Closely-located transposable elements (TEs) can induce chromosomal breakage and rearrangements via alternative transposition (AT) reactions. Our previous study showed that diverse chromosomal rearrangements were induced by two inversely-oriented Ds elements at the OsRLG5 (Oryza sativa receptor-like kinase gene 5) locus in regenerated rice plants. Here, several novel chromosomal rearrangements were identified in a population of tissue culture regenerants, and their proposed Ac/Ds-transposition mechanisms were discussed. In the first type of event, AT was induced by the same Ds element on each of two sister chromatids and resulted in the inversion of genomic DNA flanking the Ds element. In the second type of event, DNA segments of the inter-transposon segment (ITS) region were deleted or inverted. This novel local rearrangement likely resulted from an AT reaction of two directly-oriented Ds elements located on the same chromatid. The 5' and 3' termini of two Ds elements were re-inserted into two different sites inside the ITS, which generated the subsequent deletion and inversion. In the third type of event, two inversely-oriented Ds elements induced homologous recombination and chromosomal translocation. Together, these results showed the diversity of Ac/Ds-mediated chromosomal rearrangements and demonstrated the utility of the experimental system for examining the mechanisms underlying Ac/Ds AT reactions.

Purpose – The purpose of this paper is to analyze the green contradiction between China’s NEVs subsidy policies and WTO rules. It proposes resolutions for China and South Korea from the perspective of GATT Article 20 and the US New Climate Bill. Design/Methodology/Approach – Based on the investigation of NEVs in the market, this paper finds that relevant effective subsidy measures can promote China’s NEVs development. Moreover, through case study and literature, this paper also analyzes the compliance of China’s NEVs subsidy measures under the SCM Agreement. Finally, it puts forward relevant implications for the NEVs development of China and South Korea. Findings – This paper studies credit preference, financing support and LCRs, which may be determined to be prohibited subsidies and production subsidies, Tax incentives and price support may be determined to be actionable subsidies. Subsidies for specific NEV enterprises or regions may be deemed to de jure or de facto specific subsidies with disordering global trade order. Research Implications – This study has far-reaching significance in promoting the reform of WTO related- subsidy regulations and formulating a special RE subsidy agreement under the multilateral trade system, which will resolve the conflicts of the environmental and energy trade under the background of low-carbon energy transition.
Compaction techniques and construction parameters of loess as filling material
Hu, Chang-Ming,Wang, Xue-Yan,Mei, Yuan,Yuan, Yi-Li,Zhang, Shan-Shan Techno-Press 2018 Geomechanics & engineering Vol.15 No.6
Loess often causes problems when used as a filling material in the construction of foundations. Therefore, the compaction technique, shear behavior, and bearing capacity of a filled foundation should be carefully considered. A series of tests was performed in this study to obtain effective compaction techniques and construction parameters. The results indicated that loess is strongly sensitive to water. Thus, the soil moisture content should be kept within 12%-14% when it is used as a filling material. The vibrating-dynamic combination compaction technique is effective and has fewer limitations than other methods. In addition, the shear strength of the compacted loess was found to increase linearly with the degree of compaction, and the soil's compressibility decreased rapidly with an increase in the degree of compaction when the degree of compaction was less than 95%. Finally, the characteristic value of the bearing capacity increased with an increase in the degree of compaction in a ladder-type way when the degree of compaction was within 92%-95%. Based on the test data, this paper could be used as a reference in the selection of construction designs in similar engineering projects.

MicroRNAs (miRNAs) broadly regulate normal biological functions of bone and the progression of fracture healing and osteoporosis. Recently, it has been reported that miR-1224-5p in fracture plasma is a potential therapy for osteogenesis. To investigate the roles of miR-1224-5p and the Rap1 signaling pathway in fracture healing and osteoporosis development and progression, we used BMMs, BMSCs, and skull osteoblast precursor cells for in vitro osteogenesis and osteoclastogenesis studies. Osteoblastogenesis and osteoclastogenesis were detected by ALP, ARS, and TRAP staining and bone slice resorption pit assays. The miR-1224-5p target gene was assessed by siRNA-mediated target gene knockdown and luciferase reporter assays. To explore the Rap1 pathway, we performed high-throughput sequencing, western blotting, RT-PCR, chromatin immunoprecipitation assays and immunohistochemical staining. In vivo, bone healing was judged by the cortical femoral defect, cranial bone defect and femoral fracture models. Progression of osteoporosis was evaluated by an ovariectomy model and an aged osteoporosis model. We discovered that the expression of miR-1224-5p was positively correlated with fracture healing progression. Moreover, in vitro, overexpression of miR-1224-5p slowed Rankl-induced osteoclast differentiation and promoted osteoblast differentiation via the Rap1-signaling pathway by targeting ADCY2. In addition, in vivo overexpression of miR-1224-5p significantly promoted fracture healing and ameliorated the progression of osteoporosis caused by estrogen deficiency or aging. Furthermore, knockdown of miRNA-1224-5p inhibited bone regeneration in mice and accelerated the progression of osteoporosis in elderly mice. Taken together, these results identify miR-1224-5p as a key bone osteogenic regulator, which may be a potential therapeutic target for osteoporosis and fracture nonunion.
A Fast Immune Recognition Model based on Immune Response
Yuan Tao,Min Hu 보안공학연구지원센터 2014 International Journal of Multimedia and Ubiquitous Vol.9 No.11
This paper proposes a fast immune recognition model based on immune response. Inspired by biological immune system, AIS for anomaly detection has been adopted widely because of its analogy with body resistance in the immune system provided against agents which causes diseases. This paper mainly studies correspondence between immune response and anomaly detection. Compared with traditional AIS, the change of antigen type is judged by statistical techniques, which ignores the differences of the different systems. Antibody recognition is initiated by the proposed model only when the type of antigen has changed, which improves the efficiency of the algorithm. Complexity analysis shows the proposed algorithm is a linear algorithm. The usefulness of the proposed model is demonstrated through experiments. The experiments illustrate the availability and feasibility of the model.

Chicken are considered as the most important source of human infection by Campylobacter jejuni, which primarily arises from contaminated poultry meats. However, the genes expressed in vivo of the interaction between chicken and C. jejuni have not been screened. In this regard, in vivo-induced antigen technology (IVIAT) was applied to identify expressed genes in vivo during interaction between chicken and C. jejuni, a prevalent foodborne pathogen worldwide. Chicken sera were obtained by inoculating C. jejuni NCTC 11168 into Leghorn chickens through oral and intramuscular administration. Pooled chicken sera, adsorbed against in vitrogrown cultures of C. jejuni, were used to screen the inducible expression library of genomic proteins from sequenced C. jejuni NCTC 11168. Finally, 28 unique genes expressed in vivo were successfully identified after secondary and tertiary screenings with IVIAT. The genes were implicated in metabolism, molecular biosynthesis, genetic information processing, transport, regulation and other processes, in addition to Cj0092, with unknown function. Several potential virulence-associated genes were found to be expressed in vivo, including chuA, flgS, cheA, rplA, and Cj0190c. We selected four genes with different functions to compare their expression levels in vivo and in vitro using real-time RT-PCR. The results indicated that these selected genes were significantly upregulated in vivo but not in vitro. In short, the expressed genes in vivo may act as potential virulence-associated genes, the protein encoded by which may be meaningful vaccine candidate antigens for campylobacteriosis. IVIAT provides an important and efficient strategy for understanding the interaction mechanisms between Campylobacter and hosts.
