( Jia Fei Hong ),( Chu Ren Huang ),( Kathleen Ahrens ) 한국언어정보학회 2007 학술대회 논문집 Vol.2007 No.-

In this study, we explore the polysemy of da3 through the ontological conceptual structure found in SUMO. First, we divide several different senses for da3, clustering physical event senses and metaphorical event senses. In here, we only focus on physical event senses of da3. From the physical event senses of da3, we divide them into two main categories: 1) hit and 2) pump. We then use SUMO ontological concepts to identify these physical senses. Finally, we can observe the common patterns of the "hit" sense group and the "pump" sense group for da3.

Su-Qian Wu,Shang-Long Gao,Hong-Hong Liu,Xin-Yi Sun,Long Hao,Le Jia,Li-Fei Pang,Shou-Hua Jia,Meng-Shi Jia 한국고분자학회 2013 Macromolecular Research Vol.21 No.6

The extraction parameters of intracellular polysaccharide (IPS) from Pleurotus citrinopileatus SM-01mycelia were optimized, and the in vitro and in vivo antioxidant activities of IPS were investigated. The optimum conditions of IPS extraction were predicted to be an ultrasonic treatment time of 664.09 s, precipitation time of 23.03h and pH 7.36, and IPS yield was estimated at 16.13%. The in vitro inhibition effects of IPS at a dosage of 5 g/L on the superoxide anion, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radicals were 73.96±4.62%, 69.2±4.37%,and 50.75±4.39%, respectively, which were 72.56±5.08%, 22.83±1.94%, and 43.93±3.26% higher than that of butylated hydroxytoluene (BHT), respectively. The reducing power of IPS was 0.9±0.07, 69.81±5.24% higher than that of BHT. The activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), catalase (CAT) and alanine aminotransferase (ALT) in mice blood were 241.38±23.19, 454.95±42.39, 60.32±5.16, and 32.39±2.54 U/mL,respectively, and the malonaldehyde (MDA) level was 9.54±0.72 nmol/mL. The results provided a reference for the large-scale extraction of IPS by P. citrinopileatus SM-01 in industrial fermentation, suggesting that the IPS can be used as a potential antioxidant, which enhances adaptive immune responses.

Jia-Fei Yao,Yu-Feng Guo,Guang-Ming Xu,Ting-Ting Hua,Hong Lin,Jian Xiao 대한전자공학회 2014 Journal of semiconductor technology and science Vol.14 No.5

In this paper, a novel low specific onresistance SOI LDMOS Device with P<SUP>+</SUP>P-top layer in the drift region is proposed and investigated using a two dimensional device simulator, MEDICI. The structure is characterized by a heavily-doped P<SUP>+</SUP> region which is connected to the P-top layer in the drift region. The P<SUP>+</SUP> region can modulates the surface electric field profile, increases the drift doping concentration and reduces the sensitivity of the breakdown voltage on the geometry parameters. Compared to the conventional D-RESURF device, a 25.8% decrease in specific on-resistance and a 48.2% increase in figure of merit can be obtained in the novel device. Furthermore, the novel P<SUP>+</SUP>P-top device also present cost efficiency due to the fact that the P<SUP>+</SUP> region can be fabricated together with the P-type body contact region without any additional mask.

Jia-Li Gu,Hong-Fei Tong,Lai-Yu Sun 한국생물공학회 2017 Biotechnology and Bioprocess Engineering Vol.22 No.1

Macroporous magnetic agarose particles (MMAPs) were prepared with calcium carbonate as the porogent by the water-in-oil suspension thermal regeneration method. MMAPs with good sphericity and appropriate particle size were obtained. The physical properties of the beads were determined and it was found that the water content (92.1%), porosity (94.4%) and mean pore diameter (120.1 nm) of the MMAPs were higher than those for the normal magnetic particles, indicating successful generation of macropores after calcium carbonate addition. Compared with normal magnetic particles, the mass transfer of biomolecules in MMAPs was remarkably enhanced. Finally, MMAPs were modified with 5-amino-benzimidazol (ABI) ligand and the adsorption capacity of IgG reached 153 mg/mL, higher than that of the normal magnetic particles (126 mg/mL). Moreover, adsorption behavior of MMAPs to IgG was little changed after twenty-five recycled use. Hence, MMAPs prepared herein showed great potential for bioseparation.

Yao, Jia-Fei,Guo, Yu-Feng,Xu, Guang-Ming,Hua, Ting-Ting,Lin, Hong,Xiao, Jian The Institute of Electronics and Information Engin 2014 Journal of semiconductor technology and science Vol.14 No.5

In this paper, a novel low specific on-resistance SOI LDMOS Device with P+P-top layer in the drift region is proposed and investigated using a two dimensional device simulator, MEDICI. The structure is characterized by a heavily-doped $P^+$ region which is connected to the P-top layer in the drift region. The $P^+$ region can modulates the surface electric field profile, increases the drift doping concentration and reduces the sensitivity of the breakdown voltage on the geometry parameters. Compared to the conventional D-RESURF device, a 25.8% decrease in specific on-resistance and a 48.2% increase in figure of merit can be obtained in the novel device. Furthermore, the novel $P^+P$-top device also present cost efficiency due to the fact that the $P^+$ region can be fabricated together with the P-type body contact region without any additional mask.

Jianfeng Hong,Fei Pan,Ziheng Zhang,Jia Teng,Dekai He 전력전자학회 2024 JOURNAL OF POWER ELECTRONICS Vol.24 No.3

Continuous mode changes during battery charging present a significant challenge for the application of inductive power transfer (IPT) in battery charging. Achieving constant-current (CC) and constant-voltage (CV) charging characteristics is crucial for its successful implementation. This paper proposes a variable static S-T/FC compensation topology based on switching state changes. It offers the advantages of being able to handle various load conditions, facilitating soft switching of the inverter throughout the operation process, and achieving CC and CV charging without changing the operating frequency of the system. The characteristics of the proposed topology were confirmed through a theoretical analysis. Additionally, a completely new parameter design method is proposed. The CC and CV characteristics of the proposed topology are verified through theoretical derivation and simulation analysis. Finally, a validation prototype is constructed to assess the feasibility and rationality of the proposed method, achieving a 3.5 A output current in the CC mode and a 70 V output voltage in the CV mode.

Equalizing charger based on multi‑windings transformer and voltage‑doubler rectifiers

Chao Wu,Hong-kai Zhang,Shan-shou Li,Zheng-fei Li,Jia-rong Kan 전력전자학회 2022 JOURNAL OF POWER ELECTRONICS Vol.22 No.2

Energy storage batteries are currently composed of a large number of low-voltage battery cells. The state of charge of the cells is different due to the characteristic differences between cells. This causes some of the cells to be over-charged during charging and some of the cells to be over-discharging during discharging. To improve this phenomenon, this paper proposes a battery charger with an equalizing function that works during the charging and discharging processes. A performance comparison among the proposed charger and other similar topologies is carried out. The operational principle of the proposed strategy is analyzed and a control strategy with only a single voltage loop is proposed, which can guarantee two-stage charging. Experimental results show that the proposed charger can simultaneously achieve a high efficiency and the requirement of voltage equalization between cells.

Yuan, Shao-Fei,Zhu, Lin-Jia,Zheng, Wei-E,Chen, Hua,Wu, Li-Li,Zhang, Wu,Sun, Hong-Yu,Chen, Wen-Jun Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.1

Aims: To investigate the relationship between the expression of ${\beta}$-tubulin III and survivin in advanced breast cancers and chemotherapeutic effects of docetaxel. Methods: Clinical pathological data of 74 patients with advanced breast cancer were retrospectively analyzed after docetaxel chemotherapy. Expression of ${\beta}$-tubulin III and survivin was assessed by immunohistochemistry and analyzed with reference to therapeutical and adverse effects of docetaxel. Results: The positive expression rate of ${\beta}$-tubulin III was 38.1% (32/84), while that of survivin was 76.2% (64/84). The effective rate (complete response + partial response) was 52.4%. That for patients with the positive expression of ${\beta}$-tubulin III or/and survivin was significantly lower than for those with negative expression (P<0.05). There were significant differences in the non-progression of median diseases, 1-year and 2-year survival rates of between the patients with positive and negative expression (P<0.05). The main side effects were myelosuppression, alimentary canal response and alopecie, no differences being observed between groups. Conclusions: The combined detection of ${\beta}$-tubulin III and survivin is a predictive index for chemotherapy effects of docetaxel in metastatic breast cancer.

Isolation and Characterization of 2,4-D Butyl Ester Degrading <i>Acinetobacter</i> sp. ZX02 from a Chinese Ginger Cultivated Soil

Xiao, Lin,Jia, Hai-fei,Jeong, In-Hong,Ahn, Young-Joon,Zhu, Yong-Zhe American Chemical Society, Books and Journals Divi 2017 Journal of agricultural and food chemistry Vol.65 No.34

<P>Strain ZX02 was isolated from Chinese ginger cultivated soil contaminated with various pesticides, which could utilize 2,4-dichlorophenoxyacetic acid butyl ester (2,4-D butyl ester) as the sole carbon source. On the basis of the sequence analysis of 16S rRNA gene as well as the morphological, biochemical, and physiological characteristics of strain ZX02, the organism belonged to Gram-negative bacterium and was identified as Acinetobacter sp. ZX02. The strain ZX02 showed a remarkable performance in 2,4-D butyl ester degradation (100% removal in <96 h) in pure culture. Strain ZX02 was sensitive to tetracycline and resistant to amoxicillin and chloramphenicol in an antibiotic sensitivity test. The curing study indicates that the gene for degradation of 2,4-D butyl ester was encoded on a single plasmid of 23 kb. The gene encoding resistance to polymixin B sulfate was also located on this plasmid. On the basis of its greater biodegradation activity, this bacterium is a potential candidate as a bioremediation agent in soils contaminated with 2,4-D butyl ester.</P>

CCR6 Is a Predicting Biomarker of Radiosensitivity and Potential Target of Radiosensitization in Rectal Cancer

Hui Chang,Jia-wang Wei,Ya-lan Tao,Pei-rong Ding,Yun-fei Xia,Yuan-hong Gao,Wei-wei Xiao 대한암학회 2018 Cancer Research and Treatment Vol.50 No.4

Purpose This study aimed to explore the functions and mechanisms of C-C motif chemokine receptor 6 (CCR6), a gene associated with progression and metastasis of colorectal cancer (CRC), in radiosensitivity of rectal cancer (RC). Materials and Methods RNA sequencing and immunohistochemical analysis on CCR6 expression were performed in pretreatment tissues of RC patients exhibiting different therapeutic effects of radiotherapy. Colonogenic survival assay was conducted in different CRC cell lines to assess their radiosensitivity. And the impact of CCR6 expression on radiosensitivity was validated through RNA interference. The DNA damage repair (DDR) abilities of cell lines with different CCR6 expression were evaluated through immunofluorescence-based H2AX quantification. Results The CCR6 mRNA level was higher in patients without pathologic complete remission (pCR) than in those with pCR (fold changed, 2.11; p=0.004). High-level expression of CCR6 protein was more common in the bad responders than in the good responders (76.3% vs. 37.5%, p < 0.001). The CRC cell lines with higher CCR6 expression (LoVo and sw480) appeared to be more radioresistant, compared with the sw620 cell line which had lower CCR6 expression. CCR6 knockdown made the LoVo cells more sensitive to ionizing radiation (sensitization enhancement ratio, 1.738; p < 0.001), and decreased their DDR efficiency. Conclusion CCR6 might affect the RC radiosensitivity through DDR process. These findings supported CCR6 as a predicting biomarker of radiosensitivity and a potential target of radiosensitization for RC patients.
