Currently, medical device manufacturers as well as metrology measurement agencies in China usually use hemodialysis machine detectors as the commonly accepted functional calibration equipment for hemodialysis machines. So far, in China, there is no experimental protocol or devices can be used to test the accuracy and reliability of hemodialysis machine detectors, therefore, a set of new metrological apparatus with the name of hemodialysis machine detectors calibration equipment, is on the way of designing in order to make a traceable system for the calibration or verification of hemodialysis machine detectors. Principles and some research methods of this calibration equipment will be discussed in this paper.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"17 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":"129822588","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 this paper, we propose a novel adaptive directional filter (ADF) to remove impulse noise completely and accurately. Firstly, we detect the impulse noise based on the observation that the directional derivative distributions around the protein spot centers and noise pixels are very different. Then, according to the bell-shaped three-dimensional appearance of protein spots, the greatest and smallest gradient directions were used to restore the noised pixels. Lastly, the pixels adjacent to the modified pixels are iteratively detected and restored until no impulse noise is detected. Experimental results on the synthetic and real 2DE images show that the proposed method performs much better than the previous approaches.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"41 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":"129832090","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, the time-variant factors such as spectrum, channel, network topology, node energy, as well as the gateway performance make the stochastic optimization problem of emergency service complex. In this paper, we create an optimum model which is based on the restless bandit theory[1], and propose an optimum algorithm for multi-path routing selection by considering the routing cross and overlap. In our algorithm, the multi-mode gateways are regarded as the key nodes to construct the routes between cognitive self-organization network and mobile cellular network. The cross and overlapped routes are taken into consideration to loosen and expand the routes set for selection. The communication process is divided into a few path decision stages, and some paths for multicast[2][3] communication are activated according to their real-time status in each stage. The trade-off between delay and energy efficiency is made for multi-path selection. Simulation results verify that our algorithm owns outstanding performance on decreasing delay and improving energy efficiency.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"8 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":"130184618","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}

The paper proposes a boosting regression algorithm, called informative prior based GRN construction (ipGRN), to perform GRN inference. The ipGRN utilizes a scale-free based informative prior as well as Bayesian criterion measure to improve inference accuracy. In comparison with three existing methods (NIMOO, lasso and NIR), the ipGRN exhibits a significant improvement of computational accuracy and effectiveness on experiments of synthetic and real datasets. Furthermore, the method was applied to breast cancer data to reconstruct a sub-network of cancer susceptibility genes and achieved better inference results in detecting cancer associated genes.","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":"130003987","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}

The basic idea of our method is to make a contour to adaptively deform so as to get a minimized given region energy function. In order to make the evolution of the contour rely less on the intensity homogeneity and achieve the purpose of adaptive segmentation of the cell nuclei, the proposed method utilizes the morphology method to initialize the active contour modelling. Then a Gaussian kernel function is used to extract the local region and defines its local region fitting energy function which approximates the image intensities on the two sides of the contour in the local region. Finally, the Split Bregman method is used to obtain a robust numerical solution and to generate the segmentation results. In our experiments, the proposed approach can obtain accurate segmentation results compared with some state-of-the-art approaches.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"30 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":"122390589","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 study and accelerate bioinformatics data analysis models, a method named data transformation graph (DTG) is introduced first. It describes scientific data analysis models by dependencies and transformations among their data items. Then, taking BLAST as an example, DTG is used to study the data dependency in this popular bioinformatics data analysis model and parallel it by both query splitting and database partition. At last, parallel versions of BLAST proposed by DTG are implemented based on a distributed data-intensive computing middleware called Robinia. The result of performance test shows that parallel BLAST can achieve near-linear speedup with good scalability, and data transformation graph can be used to study, parallelize and optimize bioinformatics analysis applications for higher performance.","PeriodicalId":119361,"journal":{"name":"2015 8th International Conference on Biomedical Engineering and Informatics (BMEI)","volume":"133 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":"127210245","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}

Based on the experimental results of end-point fluorescence detection, the microfluidic chip can be successfully used for LAMP reactions. And then our real-time fluorescence detection biomedical system with a microfluidic chip was used to implement positive reaction and negative control. The volume of the LAMP reaction was greatly reduced from about 25 μL to 2 μL~3 μL and the reaction time can be reduced from one hour to half an hour by using our real-time fluorescence detection biomedical system.
