By studying the syntax and semantic functions of the overlapped Noun- classifiers this article mainly discusses the following interesting phenomenonthe function of the overlapped noun-classifiers move towards the syntax and semantic function of verb-classifiers. Studies show that there is a continuity from the Noun-classifier (x)A to the overlapped forms AA, --AA, --A-A. From (x)A to -A-A the form is made complicated, but substantiveness is reduced in syntax, while the nature of predicate is increased. Also, the nature of description is reduced step by step, while the character of stating something is increased gradually.

Integration for Heterogeneous Manufacturing Information Systems Based on Semantic Entity

Song Yu-chuan,Xiong Jun,LI Xian-wang,Chen Xue-hai3 보안공학연구지원센터 2016 International Journal of Smart Home Vol.10 No.9

To support semantic integration for heterogeneous information systems in manufacturing enterprises, based on semantic gateway, the concept of semantic entity is defined, and the semantic entity-based integration method is studied. Semantic entity sets up conceptual structure by aggregating semantic concept from semantic gateway, and builds dynamic conceptual structure through adding or removing its general concept. By means of key business data, semantic entity identifies business object and obtains business data from its application system, and then instantiates concept structure. Based on instantiation, semantic service can obtain parameters data from business object instant, and satisfies the interface contract. Semantic entity captures data changes of business object, and then establishes status-based integration rules, defines algorithm logic of rules. By instantiating concept structure aimed to specific application system and invoking semantic service, the integration activities among information systems come true. This work has been verified by prototype system, and attained expected integration effect.

Wang, Hai-Yi,Zhao, Yu-Nian,Wu, Jian-Zhong,Wang, Zheng,Tang, Jing-Hai Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.5

Background: Magnetic resonance imaging of breast, reported to be a high sensitivity of 94% to 100%, is the most sensitive method for detection of breast cancer. The purpose of this study was to investigate our clinical experience in MRI-guided breast lesion wire localization in Chinese women. Materials and Methods: A total of 44 patients with 46 lesions undergoing MRI-guided breast lesion localization were prospectively entered into this study between November 2013 and September 2014. Samples were collected using a 1.5-T magnet with a special MR biopsy positioning frame device. We evaluated clinical lesion characteristics on pre-biopsy MRI, pathologic results, and dynamic curve type baseline analysis. Results: Of the total of 46 wire localization excision biopsied lesions carried out in 44 female patients, pathology revealed fourteen malignancies (14/46, 30.4%) and thirty-two benign lesions (32/46, 69.6%). All lesions were successfully localized followed by excision biopsy and assessed for morphologic features highly suggestive of malignancy according to the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) category of MRI (C4a=18, C4b=17, C4c=8,C5=3). Of 46 lesions, 37 were masses and 9 were non-mass enhancement lesions. Thirty-two lesions showed a continuous kinetics curve, 11 were plateau and 3 were washout. Conclusions: Our study showed success in MRI-guided breast lesion wire localization with a satisfactory cancer diagnosis rate of 30.4%. MRI-guided wire localization breast lesion open biopsy is a safe and effective tool for the workup of suspicious lesions seen on breast MRI alone without major complications. This may contribute to increasing the diagnosis rate of early breast cancer and improve the prognosis in Chinese women.

Wang, Hai Wen,Xu, Guo Dong,Zhang, Jian Rong,Yin, Xin Korean Chemical Society 2014 Bulletin of the Korean Chemical Society Vol.35 No.7

Indium tin oxide ($In_2Sn_{1-x}O_{5-y}$) nanoparticles were synthesized by hydrothermal method from stable indium tin acetylacetone complexes and postannealing at $600^{\circ}C$. The absence of chlorine ions shortened the synthesis process, decreased the particle agglomeration and improved the particle purity. The introduced complexing ligand acetylacetone decreased the obtained nanoparticle size. The improved powder properties accelerated the sintering of the $In_2Sn_{1-x}O_{5-y}$ nanoparticles and reached a relative density of 96.4% when pressureless sintered at $1400^{\circ}C$.

Calculation of Iron Losses in Inverter-fed Induction Motors based on Time-stepping FEM

Wang, Hai-Rong,Wu, Jian-Hua Journal of International Conference on Electrical 2013 Journal of international Conference on Electrical Vol.2 No.3

This paper presents a method for calculating iron losses in three-phase induction motors under the inverter supply through the field-circuit coupled time-stepping finite element method (FEM). Iron losses are calculated by using the three-term iron losses separated model and modifying the loss coefficients obtained by the iron losses curves which are provided by the manufacturer under the sinusoidal supply. Simulation results by the presented method are verified by the measured results with an error lower than 5%, confirming the validity of the proposed method. Finally, iron losses distribution of the inverter-fed three-phase induction prototype motor is shown.

Research on the Segmentation and Pick-up Algorithm of Bamboo Wood Cross-section Based on Lab Color Space

WANG Hai-feng,REN Hong-e 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.5

The accurate segmentation and extraction of bamboo cross-section image has a vital role on bamboo processing automation. The Lab color space in accordance with the color features of the bamboo wood cross-section is chosen in this paper. The bamboo cross-section image segmentation and extraction algorithm based on the clustering theory is proposed. The algorithm firstly takes advantage of the character that the colors represented by channel a and channel b of the Lab color space accord with the color of the bamboo wood, to be combined feature vector. Then the algorithm uses the k-mean clustering algorithm to classify the eigenvectors to realize the segmentation of the bamboo wood cross-section. At last the circle fitting algorithm is used to realize the final frame of the bamboo wood cross-section. The results of the experiments show that the algorithm can be used to realize the complete segmentation of the cross-section image of bamboo wood, and to frame the results correctly, the time performance of which can meet the requirements of the subsequent processing.

Wang, Chao,Ma, Hong-Xi,Jin, Mei-Shan,Zou, Ya-Bin,Teng, Yong-Liang,Tian, Zhuang,Wang, Hai-Ying,Wang, Yin-Ping,Duan, Xiu-Mei Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.10

Matrix metalloproteinase (MMP)-2 and MMP-9 are important proteases involved in invasion and metastasis of various tumors. Extra-gastrointestinal stromal tumors (EGISTs) are rare neoplasms. This study was performed to assess MMP-2 and MMP-9 expression in EGIST tissue samples for association with clinicopathological data from the patients. Twenty-one surgical EGIST tissue specimens were collected for analysis of MMP-2 and MMP-9 expression using immunohistochemistry. MMP-2 and MMP-9 proteins were expressed in all of the epithelial cell types of EGISTs, whereas they were only expressed in 75% of the spindle cell type, although there was no statistically significant difference (p>0.05). Expression of MMP-2 and MMP-9 proteins was associated with tumor size, mitotic rate, tumor necrosis, and distant metastasis (p<0.05). MMP-2 expression was linked with MMP-9 levels (p<0.05). However, there was no correlation between MMP-9 expression and age, sex, primary site, or cell morphology in any of these 21 EGIST patients (p>0.05). Moreover, expression of MMP-2 and MMP-9 proteins increased with the degree of EGIST risk. This study provided evidence of an association of MMP-2 and MMP-9 expression with advanced EGIST behavior.

Two aerobic, Gram-stain-positive, non-motile, non-sporulating coccoid strains, designated ZLJ0423T and ZLJ0321, were isolated from the faeces of Tibetan antelope (Pantholops hodgsonii). Their optimal temperature, NaCl concentration and pH for growth were 28°C, 0.5% (w/v) NaCl and pH 7.5, respectively. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains ZLJ0423T and ZLJ0321 were very similar to each other (99.8%) and had a sequence similarity of 97.0% with Georgenia satyanarayanai NBRC 107612T and Georgenia subflava CGMCC 1.12782T. Phylogenomic analysis based on 688 core genes indicated that these strains formed a clade with G. satyanarayanai NBRC 107612T and Georgenia wutianyii Z294T. The predominant cellular fatty acids were anteiso-C15:0, anteiso-C15:1 A and C16:0. The major menaquinone was MK-8(H4). The cell-wall amino acids consisted of alanine, lysine, glycine and aspartic acid, with lysine as the diagnostic diamino acid. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides and two unidentified lipids formed the polar lipid profile. The DNA G + C content of both isolates was 73.9 mol%. The digital DNA–DNA hybridization value between strains ZLJ0423T and ZLJ0321 was 91.2%, but their values with closely related species and other available type strains of the genus Georgenia were lower than the 70% threshold. On the basis of polyphasic taxonomic data, strains ZLJ0423T and ZLJ0321 represent a novel species within the genus Georgenia, for which the name Georgenia faecalis sp. nov. is proposed. The type strain is ZLJ0423T (= CGMCC 1.13681T = JCM 33470T).

Activation of JNK/p38 Pathway is Responsible for α-Methyl-n-butylshikonin Induced Mitochondria-Dependent Apoptosis in SW620 Human Colorectal Cancer Cells

Wang, Hai-Bing,Ma, Xiao-Qiong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

${\alpha}$-Methyl-n-butylshikonin (MBS), one of the active components in the root extracts of Lithospermum erythrorhizon, posses antitumor activity. In this study, we assess the molecular mechanisms of MBS in causing apoptosis of SW620 cells. MBS reduced the cell viability of SW620 cells in a dose-and time-dependent manner and induced cell apoptosis. Treatment of SW620 cells with MBS down-regulated the expression of Bcl-2 and up-regulated the expression of Bak and caused the loss of mitochondrial membrane potential. Additionally, MBS treatment led to activation of caspase-9, caspase-8 and caspase-3, and cleavage of PARP, which was abolished by pretreatment with the pan-caspase inhibitor Z-VAD-FMK. MBS also induced significant elevation in the phosphorylation of JNK and p38. Pretreatment of SW620 cells with specific inhibitors of JNK (SP600125) and p38 (SB203580) abrogated MBS-induced apoptosis. Our results demonstrated that MBS inhibited growth of colorectal cancer SW620 cells by inducing JNK and p38 signaling pathway, and provided a clue for preclinical and clinical evaluation of MBS for colorectal cancer therapy.

Hyperthermia Promotes Apoptosis and Suppresses Invasion in C6 Rat Glioma Cells

Wang, Dong-Chun,Zhang, Yan,Chen, Hai-Yan,Li, Xiao-Li,Qin, Li-Juan,Li, Ya-Juan,Zhang, Hong-Yi,Wang, Shuo Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.7

Gliomas are a group of heterogeneous primary central nervous system tumors. Hyperthermia has proven to be a potential therapeutic tool for cancers in the clinic. However, the molecular mechanisms of hyperthermia remain unclear. The objective of this study was to investigate the effects of hyperthermia on the invasiveness in C6 glioma cells and related molecular pathways. Here our data show hyperthermia stimulated the release of tumor necrosis factor-alpha (TNF-${\alpha}$) and decreased C6 glioma cell migration and invasive capability at 30, 60, 120 and 180 min; with increased spontaneous apoptosis in C6 glioma cells at 120 min. We also found mitogen-activated protein kinase (P38 MAPK) protein expression to be increased and nuclear factor-kappa B (NF-${\kappa}B$) protein expression decreased. Based on the results, we conclude that hyperthermia alone reduced invasion of C6 glioma cells through stimulating TNF-${\alpha}$ signaling to activate apoptosis, enhancing P38 MAPK expression and inhibiting the NF-${\kappa}B$ pathway, a first report in C6 rat glioma cells.
