Xiang-yang Chen,Sun-yong Wu 보안공학연구지원센터 2015 International Journal of Grid and Distributed Comp Vol.8 No.5
The management of Multi-sensors in information fusion system occupies an important role with the development of modern weapon platform. Therefore, scientific and rational management of limited sensors resources is essential or urgent, and improvement the capability of air defense operations is necessary. According to the management optimization problem in Multi-sensor optimal resource, we analyzed the definition of rough entropy and presented the method of Multi-sensor management based on rough entropy and target threat degree. By calculating rough entropy of the sensors to the target, the maximum information gain access for each sensor on each target, which acts as cost function, taking into account the target threat degree, and using a linear programming optimization assignment multi-sensor to multi-target. In this paper, we adopted maximum information gain optimization criterion in target tracking, then discussed optimization assignment problem about multi-sensor to multi-target. In addition, we are validate the optimized allocation algorithm with the experimental simulations, and case analysis shows that the effectiveness of the method.

Four metal-organic coordination polymers, {[Cd2(BIBP)2(H2DTDA)2]n · 2(H2O)} (1), [Zn (BIBP) (H2TDA)2] n (2), [Cd2(BIBP)(H2TDA)2] n (3), and [Ni2(BIBP)2(H2DTDA)2(μ-O)] n , (4) [where BIBP = 4,4′-bis(1-imidazoly)biphenyl, H2TDA = [1,1′:4′1″-terphen-yl]-3,3″-dicarboxylic acid, and H2DTDA = 2′,5′-dimethyl-[1,1′:4′,1″-terphenyl]-3,3″-dicarboxylic acid] were hydrothermally synthesized and characterized by elemental analyses, IR, TG, luminescence, and single crystal X-ray diffraction. X-Ray diffraction analysis reveals that the four complexes exhibit new frameworks due to diverse coordination conformations. The different coordination modes of the ligands BIBP and two aromatic carboxylate acids play important roles in the construction of the final structure for the complexes. X-ray structure analysis reveals that 1, 2, and 4 are 3D coordination polymers, while complex 3 is a 2D network polymer.

Xiang Li,Yong-Jo Ahn,Xiangjian Wu,Donggyu Sim 대한전자공학회 2015 대한전자공학회 학술대회 Vol.2015 No.11
This paper proposes a scene change detection method based on block level difference of a whole frame. During the detection process, every frame is divided into 64x64 blocks, and the SAD of two corresponding 64x64 blocks from the consecutive two frames will be calculated, then all the 64x64 block SAD values of two consecutive frames will be stored in a predefined matrix. For every two matrices, the difference of every two corresponding SAD elements will be calculated, the decision whether scene change detection exists will be made according to the percentage of the difference values that exceed the predefined threshold. This algorithm has over 95% recall rate and over 96% precision rate by the test of various kinds of video sequences.

The main contribution of this paper is to present a general design method of new nonlinear disturbance observer (NDO) based on tracking differentiator (TD) for uncertain dynamic system. The stability and convergence of the proposed NDO can be guaranteed by TD. This new NDO can be used to estimate many types of uncertain disturbances, and can overcome the disadvantages of existing NDOs that need the priori information concerning the upper and lower bounds of the disturbance and its ith derivative’s Lipschitz upper bound. It can be also applied in uncertain dynamic system for various purposes such as disturbance estimate and compensation, solving the problem of control input constraint, and reducing even eliminating chattering of control input. Simulation results are presented to show the effectiveness of the developed NDO.

A bottom-modified (4-position) naphthalimide derivative 1 with 1,8-naphthyridine as binding site has been designed and synthesized. Compound 1 is the first 1,8-naphthyridine-modified naphthalimide-based sensor that can detect $Hg^{2+}$ selectively with respect to ratiometric fluorescent change and blue shift in organic aqueous solution. The Job's plot and FAB mass indicate that 1 formed a 1:1 complex with $Hg^{2+}$. A top-modified naphthalimide derivative 2 with 1,8-naphthyridin as binding site has also been synthesized for comparison.
Genetic Polymorphism of MTHFR A1298C and Esophageal Cancer Susceptibility: A Meta-analysis
Tan, Xiang,Wang, Yong-Yong,Dai, Lei,Liao, Xu-Qiang,Chen, Ming-Wu Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3
Background: Associations between the methylenetetrahydrofolate reductase (MTHFR) A1298C polymorphism and esophageal cancer risk have been reported in many articles recently, but results were controversial. Therefore the present meta-analysis was conducted to to provide a more precise estimation. Methods: Odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the strength of associations. Results: Finally, six case-control studies involving a total of 1,302 cases and 2,391controls for the A1298C polymorphism were included. The meta-analysis showed that significantly increased risk for Asians (CC versus AA, OR=3.799, 95%CI=1.541-9.365, P=0.004; CCversusCA+AA, OR=3.997, 95%CI=1.614-9.900, P=0.003) and Caucasians (CC versus AA, OR=1.797, 95%CI=1.335-2.418, P=0.000; CC+CA versus AA,OR=1.240, 95%CI=1.031-1.492, P=0.022; CCversusCA+AA, OR=1.693, 95%CI=1.280-2.240, P=0.000). In addition, there was an association with risk for both ESCC (CC versus AA, OR=2.529, 95%CI=1.688-3.788, P=0.000; CCversusCA+AA, OR=2.572, 95%CI=1.761-3.758, P=0.000) and esophageal adenocarcinoma (EAC) (CC versus AA, OR=1.592, 95%CI=1.139-2.227, P=0.007; CC+CA versus AA,OR=1.247, 95%CI=1.016-1.530, P=0.035; CCversusCA+AA, OR=1.466, 95%CI=1.069-2.011, P=0.018). Conclusion: This meta-analysis suggested associations of the A1298C polymorphism with increased risk of esophageal cancer in both Asians and Caucasians. In addition, we found that the MTHFR A1298C polymorphism might influence risk ofESCC and EAC in the overall studies.

The insect midgut epithelium is generally lined with a unique chitin and protein structure, the peritrophic membrane (PM), which facilitates food digestion and protects the gut epithelium. We used gel electrophoresis and mass spectrometry to identify the extracted proteins from the silkworm PM to obtain an in-depth understanding of the biological function of the silkworm PM components. A total of 305 proteins, with molecular weights ranging from 8.02 kDa to 788.52 kDa and the isoelectric points ranging from 3.39 to 12.91, were successfully identified. We also found several major classes of PM proteins, i.e. PM chitin-binding protein, invertebrate intestinal mucin, and chitin deacetylase. The protein profile provides a basis for further study of the physiological events in the PM of Bombyx mori.
