Trichoderma spp. are widely applied, eco-friendly mycofungicides and plant growth promoters. Native Trichoderma strainsare likely to have more productive, stable biocontrol and biofertilizer activities since they are well adapted to the local environment. In this study, we isolated a native Trichoderma strain ‘Th62’ from the rhizosphere soil of wild Chelidonium majusplants in Harbin, China (126.6341°E, 45.7242°N). The isolated Trichoderma strain was identifi ed as a T. harzianum strainvia morphological observation and molecular methods based on the rDNA internal transcribed spacer region and elongationfactor-1α gene sequences. Signifi cant antagonistic activities of Th62 against fi ve soil-borne fungal phytopathogens,Fusarium oxysporum , Sclerotinia sclerotiorum , Alternaria alternata , Cytospora chrysosperma, and Rhizoctonia solani ,were confi rmed by dual-culture assays. Furthermore, the crude fermentation products of Th62 also displayed antifungalactivities against these fi ve pathogens. To evaluate the function of Th62 as a biofertilizer, we subsequently applied Th62on cockscomb ( Celosia cristata L), a plant species with both ornamental and medicinal values, by inoculation with Th62conidia at diff erent concentrations, 1 × 10 10 cfu mL −1 , 1 × 10 11 cfu mL −1 , and 1 × 10 12 cfu mL −1 . The benefi cial eff ects ofTh62 were evaluated by measuring the growth and photosynthetic traits of the inoculated cockscomb plants, and the resultsdemonstrated that Th62 signifi cantly improved the photosynthetic effi ciency, photosynthetic capacity, and the adaptabilityto intense light of the inoculated cockscomb plants compared to the controls. Consistently, Th62 inoculation signifi cantlyimproved the growth and fl ower yield of cockscomb. We presented a positive case of isolating and applying native microbialresources on local plantation practices.

Yue Hou-guang,ZhangLing,Meng Fan-jun,Songhong-hao 보안공학연구지원센터 2014 International Journal of u- and e- Service, Scienc Vol.7 No.5

The exponential growth of the data on the web makes it difficult for web users to locate and obtain the interesting information. The general web search engines, such as Google, Baidu, reduce the degree of difficulty to some extent. The rise of vertical search engine provides a promising approach to address the big challenge. A Chinese vertical search engine is urgently needed to provide professional financial information retrieval service for related financial institutions and government agencies. Therefore, in this paper we investigate, design and implement a vertical search engine in the financial domain. Based onNutch plug-in mechanism, we provide and implement the details of a vertical search engine in the financial domain, especially in the finance domain focused crawler. Experimental results show that, the finance domain focused crawler based on Nutch plug-in mechanism has good performance and can satisfy practical requirements of medium search application, and the system runs well.

Yue Guo,Hou-De Zhou,Yun-Zhi Feng 대한치과보철학회 2017 The Journal of Advanced Prosthodontics Vol.9 No.6

PURPOSE. To evaluate the sealing performance of Hybrid Coat and its influence on the shear bond strength of five dentin surface cements. MATERIALS AND METHODS. Six premolars were pretreated to expose the dentin surface prior to the application of Hybrid Coat. The microscopic characteristics of the dentinal surfaces were examined with scanning electron microscopy (SEM). Then, 40 premolars were sectioned longitudinally, and 80 semi-sections were divided into a control group (untreated) and a study group (treated by Hybrid Coat). Alloy restoration was bonded to the teeth specimen using five different cements. Shear bond strength was measured by the universal testing machine. The fracture patterns and the adhesive interface were observed using a stereomicroscope. RESULTS. SEM revealed that the lumens of dentinal tubules were completely occluded by Hybrid Coat. The Hybrid Coat significantly improved the shear bond strength of resin-modified glass ionomer cement (RMGIC) and resin cement (RC) but weakened the performance of zinc phosphate cement (ZPC), zinc polycarboxylate cement (ZPCC) and glass ionomer cement (GIC). CONCLUSION. Hybrid Coat is an effective dentinal tubule sealant, and therefore its combined use with resin or resin-modified glass ionomer cements can be applied for the prostheses attachment purpose.

Associations between ABCB1 and XPC genetic polymorphisms and risk of developing colorectal cancer (CRC) as well as clinical outcomes in CRCs with chemotherapy were investigated. A case-control study was performed on the ABCB1 C3435T, G2677T/A and XPC Lys939Gln polymorphisms in 428 CRC cases and 450 hospitalbased, age and sex frequency-matched controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assays. We observed that the ABCB1 3435CT or CC+CT variants were significantly linked with increasing risk of developing CRC (adjusted OR (95% CI): 1.814 (1.237-2.660), P=0.0022; adjusted OR (95% CI): 1.605 (1.117-2.306), P=0.0102, respectively). Moreover, the distribution frequency of XPC AC genotype or AC+CC genotypes also showed a tendency towards increasing the suscepbility for CRC (P=0.0759 and P=0.0903, respectively). Kaplan-Meier curves showed that the ABCB1 C3435T variant was associated with a tendency toward longer progression-free survival (PFS) (n=343, Log-rank test: P=0.063), and the G2677T/A variant genotypes (GT+TT+GA+AA) with a tendency for longer OS in postoperative oxaliplatin-based patients (n=343, Log-rank test: P=0.082). However, no correlation of the XPC Lys939Gln polymorphism was found with PFS and OS in patients with postoperative oxaliplatin-based chemotherapy (n=343). Our study indicated that ABCB1 polymorphisms might be candidate pharmacogenomic factors for the prediction of CRC susceptibility, but not for prognosis with oxaliplatin chemosensitivity in CRC patients.

Lexical Recoding via Bilingual Memory in Sight Interpreting : A Combined Eye-tracking and Corpus-assisted Study

Yue Lang,Linping Hou,Yuanjian He 이화여자대학교 통역번역연구소 2018 T&I review Vol.8 No.-

This paper reports the results of a triangulated study that combined eye-tracking and corpus-assisted methods on lexical recoding via bilingual memory in sight interpreting of cultural specificity (CF) from English (L2) into Chinese (L1) by student interpreters. The results show that the patterns of eye-tracking and those of the experimental corpus both indicate that CF causes processing load to increase lexical recoding, and the fact that the two patterns converge on one another implies that lexical recoding relies also crucially on bilingual memory. Moreover, we argue that a theoretical element should be an integral part of triangulation. To a larger extent the theory may reflect the underlying bilingual-processing process for translating and interpreting, the more feasible it is in offering a unified account for experimental as well as corpus-extracted data patterns. Further research is needed.

Experimental study on the injection and spray characteristics of biodiesel and diesel fuel within a common rail system

( Hao Yue Zhu ),( Zhen Huang ),( Jin Xiao ),( Jun Xing Hou ) 한국액체미립화학회 2010 한국액체미립화학회 학술강연회 논문집 Vol.2010 No.-

In this paper, the injection characteristics and macroscopic spray behavior of biodiesel and diesel fuel within a common rail system are investigated. The injection rate is measured with Bosch method, spray visualization system is employed to study the macroscopic spray characteristics of both fuels. The results show that the injection delays of biodiesel and diesel are almost the same. Comparing to diesel, injection duration of biodiesel is a little longer and injection fuel quantity is a little larger. The macroscopic spray result shows, with increased injection pressure, the tip penetration of biodiesel becomes longer and the spray cone angle becomes larger. When ambient pressure increases, the injection tip penetration becomes shorter and the spray cone angle becomes larger. Comparing to diesel, injection tip penetration of biodiesel is longer and spray cone angle is smaller, because the kinematic viscosity and surface tension of biodiesel are larger than those of diesel. The difference of spray characteristics of both fuels is no longer obvious under higher injection pressure. With increased ambient pressure, the difference of spray tip penetration of both fuels becomes larger, and the difference of spray cone angle become smaller.

A Study on Group Buying of O2O Mode using Generalized Stochastic Petri Nets

Fangfang Hou,Shuyun Zhang,Yue Wang 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.3

This paper proposes a Group Buying model (paid in advance) of online-to-offline mode using Generalized Stochastic Petri Nets. As the time cost of consumers is getting higher and higher, time efficiency is getting much more important in all aspects of life, especially in catering industry, and one way that can lead to direct communication between store owners and consumers is Group Buying of online-to-offline mode, the center of which is the brand building and service efficiency. Although researches based on both users’ and sellers’ perspective about online buying are very rich, these findings are not entirely applicable for this new e-commerce model, and most of current research on online-to-offline mode use qualitative methods. More importantly, few researchers have concerned about the efficiency of Group Buying process and come up with related solutions to improve it. By constructing a business model of GB and conducting time efficiency and performance analysis on it, we find that the key transitions of the system only take up less than half of the time before the whole process has been completed. And when we shorten the feedback process, the percentage of finishing consumption in physical store in the whole Group Buying model can be improved by 14.5%. Thus, we suggest that suppliers and sellers should be more focused and efficient in encouraging customers review timely as well as giving consumers feedback as soon as possible, since consumer comments are proved to be significantly important for the retailers. Besides, site operators and store sellers can also use other ways like WeChat and microblogging to promote their site linkages and gain more market share.

All-trans-retinoic Acid Promotes Iodine Uptake Via Up-regulating the Sodium Iodide Symporter in Medullary Thyroid Cancer Stem Cells

Tang, Min,Hou, Yan-Li,Kang, Qiang-Qiang,Chen, Xing-Yue,Duan, Li-Qun,Shu, Jin,Li, Shao-Lin,Hu, Xiao-Li,Peng, Zhi-Ping Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Recently, the main therapy of medullary thyroid cancer (MTC) is surgical, but by which way there is a poor prognosis with a mean survival of only 5 years. In some cases, some researchers found that it is the medullary thyroid cancer stem cells (MTCSCs) that cause metastasis and recurrence. This study aimed to eradicate MTCSCs through administration of all-trans-retinoic acid (ATRA). Here we demonstrate that MTCSCs possess stemlike properties in serum-free medium. The ABCG2, OCT4 and sodium iodide symporter (NIS) were changed by ATRA. Additionally, we found that ATRA can increase the expression of NIS in vivo. All the data suggested that ATRA could increase the iodine uptake of MTCSCs through NIS.

Investigations on seismic performance of nuclear power plants equipped with an optimal BIS-TMDI considering FSI effects

Zhang Shuaijun,Hou Gangling,Yang Chengyu,Yue Zhihua,Wang Yuzhu,He Min,Sun Lele,Cai Xuesong 한국원자력학회 2024 Nuclear Engineering and Technology Vol.56 No.7

This paper introduces a base isolation system-tuned mass damper inerter (BIS-TMDI) hybrid system to the AP1000 nuclear power plant (NPP), which reduces seismic damage potential of the NPP structure. The effects of fluid-structure interaction (FSI) caused by the passive containment cooling system water storage tank (PCCWST) on NPP’s seismic performance are investigated. The FSI of water tank theoretical model is considered based on the Housner’s model, and a series of time history analyses are performed to prove the rationality of the proposed model. Three single-objective optimization strategies are employed to minimize the relative displacement variance and absolute acceleration variance of the upper structure, as well as the filtered energy index (FEI). Furthermore, a multi-objective optimization strategy considering all these three indexes is proposed to obtain optimal parameters of vibration control. The influence of vibration control strategies on the relative deformation and acceleration of the upper structure is explored with various water level ratios. The analytical results indicate that the proposed BIS-TMDI strategy has significantly reduced the NPP structure’s seismic response. The effectiveness of the vibration control strategy is influenced by the water level ratio, emphasizing the significance of designing an appropriate water level ratio to reduce NPP structure’s seismic response.

Background: Feline mammary carcinoma is the third most common cancer that affects female cats. Objectives: The purpose of this study was to screen differential serum proteins in feline and clarify the relationship between them and the occurrence of feline mammary carcinoma. Methods: Chinese pastoral cats were used as experimental animals. Six serum samples from cats with mammary carcinoma (group T) and six serum samples from healthy cats (group C) were selected. Differential protein analysis was performed using a Label-free technique, while parallel reaction monitoring (PRM) was performed to verify the screened differential proteins. Results: A total of 82 differential proteins were detected between group T and group C, of which 55 proteins were down regulated and 27 proteins were up regulated. Apolipoprotein A-I, Apolipoprotein A-II (ApoA-II), Apolipoprotein B (ApoB), Apolipoprotein C-III (ApoC-III), coagulation factor V, coagulation factor X, C1q, albumen (ALB) were all associated with the occurrence of feline mammary carcinoma. Differential proteins were involved in a total of 40 signaling pathways, among which the metabolic pathways associated with feline mammary carcinoma were the complement and coagulation cascade and cholesterol metabolism. According to the Label-free results, ApoB, ApoC-III, ApoA-II, FN1, an uncharacterized protein, and ALB were selected for PRM target verification. The results were consistent with the trend of the label-free. Conclusions: This experimen is the first to confirm ApoA-II and ApoB maybe new feline mammary carcinoma biomarkers and to analyze their mechanisms in the development of such carcinoma in feline.
