It can protect structures and edge weights of weighted social networks in multiple release scenarios. First, it partitions weighted social networks into t sub-graphs by the segmentation method based on vertex cluster using edge space of graph theory, describes these sub-graphs by vectors, and constructs vector set models of weighted social networks. Then, it adopts weighted Euclidean distance as the metrics of vectors similarity to construct the released candidate sets of t sub-graphs according to the threshold designated by publishers. Finally, it randomly selects vectors from the candidate sets to construct the released vector set, and builds the published weighted social networks based on the released vector set. The proposed method can resist multiple vertex recognition attacks, force the attackers to re-identify in a large result set that the existential probabilities of the vectors are same, and increase the uncertainty of recognition. The experimental results on the actual datasets demonstrate that the proposed method can preserve the security of individuals' privacy, meanwhile it can protect some structure characteristics for social networks analysis and improve the released data utility.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133564468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to prevent the disease from spreading further, it is necessary to have a research of the most dangerous Zaire Ebola virus at the molecular level. Comparing to Zaire EBOV in 1976, the evolution result of the virus in 2014 can instruct people to take steps and have the proper precaution program. The comparison and phylogenic tree methods are able to reveal the degree of the evolution whose processing is conservative at present. With the help of ClustalX, the amount of mutations in different parts of Zaire EBOV nucleotide sequences can be analyzed. Only 3% bases changed in the sequences of 2014. Phylogenic tree can reflect the relationship of the sequences in diverse years, and they are homology. Combining the changes of base with corresponding amino acid, the conservation of the virus can be demonstrated again. It's significant to have a continuous concern of the Zaire virus, as it may have potential evolution.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116543659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And one of the main problems caused by these faults is the control flow errors in the program. This paper proposes a software-implemented control flow error detecting and correcting approach for the linear assembly named DCCLA. DCCLA firstly divides the program into loop blocks and non-loop blocks and assigns the formatted labels for the blocks. Then based on the mechanism of instructions counting, DCCLA inserts counting and comparing instructions into every block, with the purpose of detecting and correcting the control flow errors occurred inter-block and intra-block. In order to correct the data flow errors caused by the control flow errors, DCCLA backups the loop state and live variables. One advantage of DCCLA is that it can be configured flexibly according to the requirement of reliability and performance. The results of fault injection experiment shown that, the average fail rate of programs with DCCLA has decreased to 4.25% with the cost of increasing the average executing time by 41.7% and increasing the average program space by 46.7% DCCLA has the least influence on performance and space overhead and correspondingly higher reliability among three typical control flow detecting algorithms.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116703338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All the patients underwent conventional MRI and contrast-enhanced MRI, and DWIBS used two types b-value: ordinary b-value (b=0, 1000s/mm2) and high-b-value (b=3000s/mm2). Evading cystic necrosis area, the signal intensity (SI), background noise and apparent diffusion coefficient (ADC) value of tumor parenchyma and adjacent normal white matter were measured. The averages of signal to noise ratio (SNR), contrast to noise ratio (CNR) and contrast ratio (CR) were computed from these data. The lesion diagnosis accuracy rate of high-b-value DWIBS was better than that of ordinary b-value. On high-b-value DWIBS sequence, the CNR, CR and SI-lesion/ SI-normal of brain metastasis was significant higher than that of ordinary b-value DWIBS sequence (P<;0.05). And the SNR was significant lower than that of ordinary b-value DWIBS sequence (P <; 0.05). The CNR, CR of Contrast-enhanced T1WI was significant higher than that of normal brain tissue (P<;0.05). The ADC value in High-b-value DWIBS sequence was lower than that in ordinary b-value DWIBS sequence (P <; 0.05). Conclusion High-b-value DWIBS sequence showed a great value in detecting cerebral metastases. It was a simple method and could be avoiding potential harm of contrast agent for the human bodies.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127656638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
