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}

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}

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}

However, most of the existing clustering protocols focus on the network model with uniform node distribution. They cannot effectively apply to the real network where the sensor nodes are randomly non-uniformly deployed. In this paper, we propose an energy-balanced clustering routing protocol (EBCRP) based on task separation. In this scheme, the network is firstly divided into clusters by using global information. And each of them has the same number of sensor nodes in order to balance the energy consumption of intra-cluster. In succession, task separation, the tasks of traditional single cluster head are separated and achieved by two cluster heads respectively, is proposed to reduce the traffic burden for single cluster head. Then, we explore an energy-efficient and reliable inter-cluster routing algorithm, which considers comprehensively three factors: residual energy, distance and available buffer space of nodes. Simulation results and performance evaluation of EBCRP show significant improvement in network lifetime and energy balance.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"44 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":"131961624","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}
