APPROXIMATE PROCESSING OF EVIDENCE ON AN INFINITE FRAME
Duan, Xin Sheng 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
In [2], Shafer extends belief functions from the case where frame Ω is finite to the case where frame Ω is infinite. But he does not give any methods to treat belief functions on an infinite frame. In this paper, using the thery of rough sets that presented by Z.Pawlak in 1982,I present a method to process the evidence on an infinite frame. So the problem of evidence processing on an infinite frame may be solved in practice.

Focused on the issue that motion blurred permuted alias image blind separation, an algorithm using image enhancement based on nonsubsampled contourlet transform (NSCT) domain was proposed. Firstly, permuted alias image was decomposed into low-frequency sub-band and high-frequency sub-bands, which were obtained by spare decomposition based on NSCT domain. Coefficients of high-frequency sub-bands were enhanced according to Bayesian shrinkage threshold and nonlinear gain function, and the enhanced version was got by this method. Then the permuted alias image and the enhanced version were blocked, the correlation coefficients were estimated by each corresponding sub-block, because the permuting image was changed larger, the permuting image could be separated by using threshold method. Experimental results show that the proposed algorithm can separate the permuting image effectively from the permuted alias image in spite of the motion blurred direction, blur degree, size, location and the number of permuting image.

Necroptosis is the major cause of death in alveolar epithelial cells (AECs) during acute lung injury (ALI). Here, we report a previously unrecognized mechanism for necroptosis. We found an accumulation of mitochondrial citrate (citratemt) in lipopolysaccharide (LPS)-treated AECs because of the downregulation of Idh3α and citrate carrier (CIC, also known as Slc25a1). shRNA- or inhibitor–mediated inhibition of Idh3α and Slc25a1 induced citratemt accumulation and necroptosis in vitro. Mice with AEC-specific Idh3α and Slc25a1 deficiency exhibited exacerbated lung injury and AEC necroptosis. Interestingly, the overexpression of Idh3α and Slc25a1 decreased citratemt levels and rescued AECs from necroptosis. Mechanistically, citratemt accumulation induced mitochondrial fission and excessive mitophagy in AECs. Furthermore, citratemt directly interacted with FUN14 domain-containing protein 1 (FUNDC1) and promoted the interaction of FUNDC1 with dynamin-related protein 1 (DRP1), leading to excessive mitophagy-mediated necroptosis and thereby initiating and promoting ALI. Importantly, necroptosis induced by citratemt accumulation was inhibited in FUNDC1-knockout AECs. We show that citratemt accumulation is a novel target for protection against ALI involving necroptosis.

Purpose: Numerous studies have evaluated the association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma risk in the Chinese Han population. However, the results have been inconsistent. We therefore here examined whether the XRCC1 Arg399Gln gene polymorphism confers hepatocellular carcinoma risk by conducting a meta-analysis. Methods: PubMed, Google scholar and China National Knowledge Infrastructure databases were searched for eligible articles in English and Chinese that were published before April 2012. Results: 6 studies involving 1,246 patients with hepatocellular carcinoma and 1,953 controls were included. The association between XRCC1 Arg399Gln gene polymorphism and hepatocellular carcinoma in the Chinese Han population was significant under GG vs AA (OR = 1.48, 95% CI = 1.13 to 1.94). Limiting the analysis to the studies with controls in the Hardy-Weinberg equilibrium, the results were persistent and robust. Conclusions: In the Chinese Han population, the XRCC1 Arg399Gln gene polymorphism is associated with an increased hepatocellular carcinoma risk.
MEMD Interval Threshold Filter and Twin SVM for Electromagnetic Template Attack
Duan Li,Hong-xin Zhang,Qiang Li,Xinjie Zhao,Pengfei He 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.11
To overcome the dependence on prior knowledge of traditional filtering algorithm, this paper proposes a novel non-parameter and adaptive multivariate empirical mode decomposition interval threshold (MEMD-IT) denoising approach for signal preprocessing of electromagnetic template attack(ETA). MEMD-IT can reduce the discontinuity induced by traditional MEMD-DT and aims to remove the Gaussian noise coupled into side-channel electromagnetic radiations. The proposed method and some other filters such as butterworth low-pass filter(BLPF),wavelet threshold denoising and MEMD direct threshold (MEMD-DT) denoising are applied to analyze the electromagnetic radiation traces intercepted while cipher device was implementing RC4 encryption algorithm. Furthermore, twin SVM multi-class classifier based ETA was performed to evaluate the attack results. In the same attack scenario, the highest predictive success rate for 9 Hamming Weights of the key reached 92%,90%,84%,83% and 73% for MEMD-IT, WFTF, MEMD-DT,WULETF and BLPF preprocessing methods, respectively. The experiment results indicate that our proposed scheme has a significant performance compared with the traditional ETA.

During oocyte meiosis, a spindle forms in the central cytoplasm and migrates to the cortex. Subsequently, the oocyte extrudes a small body and forms a highly polarized egg; this process is regulated primarily by actin. ROCK is a Rho-GTPase effector that is involved in various cellular functions, such as stress fiber formation, cell migration, tumor cell invasion, and cell motility. In this study, we investigated possible roles for ROCK in mouse oocyte meiosis. ROCK was localized around spindles after germinal vesicle breakdown and was colocalized with cytoplasmic actin and mitochondria. Disrupting ROCK activity by RNAi or an inhibitor resulted in cell cycle progression and polar body extrusion failure. Time-lapse microscopy showed that this may have been due to spindle migration and cytokinesis defects, as chromosomes segregated but failed to extrude a polar body and then realigned. Actin expression at oocyte membranes and in cytoplasm was significantly decreased after these treatments. Actin caps were also disrupted, which was confirmed by a failure to form cortical granule-free domains. The mitochondrial distribution was also disrupted, which indicated that mitochondria were involved in the ROCK-mediated actin assembly. In addition, the phosphorylation levels of Cofilin, a downstream molecule of ROCK, decreased after disrupting ROCK activity. Thus, our results indicated that a ROCK-Cofilinactin pathway regulated meiotic spindle migration and cytokinesis during mouse oocyte maturation.

Antheraea pernyi is an edible insect with important economic value in both traditional and non-traditional ap plications. Elucidating the details of gene expression variation among different A. pernyi larval tissues will greatly improve our knowledge about A. pernyi biology and promote its protection and breeding. Here, tissue-based transcriptome and gene co-expression network analysis were performed for the fifth-instar larval tissues of testis, midgut, Malpighian tubule, head, trachea, silk gland, integument, hemocyte, ovary, and fat body. A total of 1,991 tissue-associated genes, including 62 transcription factor-encoding genes, were correlated with the development and functions of these tissues. Moreover, 10 gene co-expression modules that were highly corre lated with the tissues were also determined. The most important 30 genes with top connectivity in each module were identified as hub genes to form the core co-expression network with important biological functions in the corresponding tissues. Based on these resources, further in-depth studies should be conducted to determine the roles of candidate genes and transcription factors governing tissue development and trait formation in A. pernyi.

In this study, we describe a novel ecological self-incompatibility (SI) line HE97 in maize. The main environmental factors influencing the inbred line characteristics were identified through field sowing trials during a two-year study period (2001 and 2002). The results showed that daily minimum temperature had the greatest effect on floral morphology and breeding system of the SI line. In staminate floret differentiation, when the daily minimum temperature exceeded 24℃, the line exhibited complete self-compatibility; however SI was observed when the daily minimum temperature was below 20℃. Therefore, we characterized the line as exhibiting thermo-sensitive genic self-incompatibility (TGSI). A set of F2 and F2:3 populations, derived from the inbred lines HE97 and Z58, were evaluated for two years to elucidate the TGSI line patterns of inheritance. Classical genetic analyses and QTL mapping results revealed that HE97 self-incompatibility was governed by a single allele, named here as tgsi1. The tgsi1 gene was mapped to chromosome 2 between SSR markers nc131 and bnlg1633, with a distance of 2.40 cM from nc131 and 2.44 cM from bnlg1633.
