An Improved Model of General Data Publish/Subscribe Based on Data Distribution Service
Shufen Liu,Xuejun Ma,Xinyong Wang 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.11
Most existing data publish/subscribe systems applied in a particular field, the lack of generality. In order to satisfy the general support for interdisciplinary model, proposed an improved model of general data publish/subscribe. The model supports the configuration and modification of the underlying data types. In order to avoid the impact on the application layer while changing the underlying DDS product, proposed an encapsulation on DDS based on the abstract factory pattern. Finally, through simulation experiments to verify the feasibility of the proposed model, the simulation results show that the improved model can be well applied to various types of data publish/subscribe occasions, with high performance.
The Research of Ecological planting construction epidermis design based on the concept of BBL
Liu Ruyi,Wang Shufen 국제온돌학회 2013 International Journal of Ondol Vol.6 No.1
The core of vertical space greening of urban architecture which is an effective approach to build the green healthy living environment and to increase urban green space, is the ecological planting epidermis design. By means of learning the experience of international ecological planting design of construction epidermis, the paper reviews principles of ecological planting design of construction epidermis and the relationship between this and planting design, which bases on the concept of BBL, the bioclimatic buffering layer. Furthermore, it aims to find new creative ideas of the combination of green plants and construction epidermis design, in order to provide references for Chinese construction epidermis design practice.

We report the facile synthesis of small gold nanoparticles stabilized by carbon nanospheres (Au@C) for highly active and selective hydrogenation of 4-nitrobenzaldehyde. The formation of such a Au@C unique structure can be attributed to the high distribution of Au(III) species in the melamine-formaldehyde resin nanospheres, which were formed via the coordination of Au(III) with the abundant imino groups of melamine-formaldehyde pre-polymer. After the subsequent condensation and confined in situ reduction, small gold nanoparticles, and carbon nanospheres were formed simultaneously. Under the reaction conditions of 80 °C and 1.6 MPa, 99.3% conversion and >99% selectivity were achieved for the hydrogenation of 4-nitrobenzaldehyde to 4-aminobenzaldehyde.
An Approach of Information Extraction Based on Dom Tree and Weight Value
Haitao Wang,Shufen Liu 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.10
Eliminating noisy information and extracting information content from web pages are increasing to become an important research issue in information retrieval field. In this paper, we present an approach of information extraction based on Dom tree and weight value calculation, which contains the following steps, parse the web page to construct the Dom tree, extract the title and keywords, calculate the weight value and obtain the content. The experimental result shows that this method has the higher accuracy ratio by the various themes content extraction.
An Effective Feature Selection Approach Using the Hybrid Filter Wrapper
Haitao Wang,Shufen Liu 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.1
Feature selection is an important data preprocessing technique and has been widely studied in data mining, machine learning and granular computing. In this paper, we introduced an effective feature selection method using the hybrid approaches, that is, use the mutual information to select the candidate feature set, then, obtain the super-reduct space from the candidate feature set by a wrapper search approach, finally, the wrapper method determined to select the proper features. The experimental results show that our approach owned the obvious merits in the aspect of classification accuracy ratio and number features selected by extensive comparing with other methods.

Previous studies demonstrated that depression is more prevalent in women with polycystic ovary syndrome (PCOS). In this study, we aimed to determine whether amitriptyline (AMT), an antidepressant drug, plays a role in preventing PCOS. The results showed that AMT modified ovarian morphology improved the ovarian functions and estrus cycle in estradiol valerate (EV)-induced polycystic ovary (PCO). AMT restored the levels of estradiol (E2), testosterone (T) and progesterone (P4) to normal, and elevated the level of luteinizing hormone (LH) in EV-induced PCO. No significant changes in follicle stimulating hormone (FSH) levels were observed in rats with EV or AMT treatment. The restoration of norepinephrine (NE) level was detected in rats with EV-induced PCO. AMT also altered the expression levels of steroidogenesis genes and beta2-adrenoceptor (beta2-AR) in EV-induced PCO. Our data revealed that AMT improves the ovarian morphology and modifies ovarian expression of beta2-AR and steroidogenesis genes in rats with EV-induced rat PCO. Our data provide support for the hypothesis that AMT is considered as a candidate drug for preventing and treating PCOS along with depression.

Aspergillus flavus is a saprophytic fungus that contaminates crops with carcinogenic aflatoxin. In the present work, the antifungal effects of volatile organic compounds (VOCs) from Streptomyces alboflavus TD-1 against A. flavus were investigated. VOCs from 8-day-old wheat bran culture of S. alboflavus TD-1 displayed strong inhibitory effects against mycelial growth, sporulation, and conidial germination of A. flavus. Severely misshapen conidia and hyphae of A. flavus were observed by scanning electron microscopy after exposure to VOCs for 6 and 12 h, respectively. Rhodamine 123 staining of mitochondria indicated that mitochondria may be a legitimate antifungal target of the VOCs from S. alboflavus TD-1. Furthermore, the VOCs effectively inhibited aflatoxin B1 production by downregulating genes involved in aflatoxin biosynthesis. Dimethyl trisulfide and benzenamine may play important roles in the suppression of A. flavus growth and production of aflatoxin. The results indicate that VOCs from S. alboflavus TD-1 have tremendous potential to be developed as a useful bio-pesticide for controlling A. flavus.
