In order to meet this growing need numerous portable ultrasound systems have been proposed. The design of portable systems is a very challenging task, especially for volumetric imaging system which utilize transducers with hundreds and thousands of elements. This study presents a new low-cost, portable volumetric ultrasound system for ambulatory healthcare monitoring which can serve as an enhanced alternative to the existing portable systems. All hardware components along with vital processes that are performed during the image acquisition, are presented in details. Initially, the design of the proposed 2-D phased array transducer is introduced and its performance is evaluated. Secondly, all hardware components of the system are explicitly presented and finally a software-based methodology for image enhancement that is based in image fusion and a super - resolution technique is described. The imaging quality of the designed transducer is investigated through simulations using FIELD II. Additionally, preliminary simulation results of the applied methodology for 3D images, show significant image quality improvement, especially in the regions where recording from all transducers was possible.","PeriodicalId":422807,"journal":{"name":"2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE)","volume":"320 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115280606","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 development of new technologies is revolutionizing genome-wide analysis and scientists' abilities to have a better understanding of the biological meaning but inferring gene regulatory networks from such data is still a major challenge in systems biology. Complex reactions at the molecular level in living cells and such knowledge, as it relates to specific phenotype, necessarily implies that a key molecular target should be considered within the framework of its gene regulatory network. The objective of our study is to explore the effect of proteins under specific conditions (e.g. treatment or starvation), in functional sub-pathways for specific phenotype. Using public microarray expression datasets for glioma and the KEGG human gene regulatory networks as proof of concept, we identified disrupted sub-paths due to STAT3 on functional glioma pathways. We expect that the proposed algorithmic approach could aid researchers to determine the biological relevance of the binding sites over functional sub-paths and provide insights for new disease treatments.","PeriodicalId":422807,"journal":{"name":"2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129035270","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 Fourier transform and the short time Fourier transform are the widely used frequency and time-frequency analysis methods for extracting information from BSs with fixed frequency and time-frequency resolution respectively. However, in order to derive relevant information from non-stationary BSs, an appropriate analysis method which exhibits adjustable time-frequency resolution is needed. The wavelet transform (WT) can be used as a mathematical microscope in which the time-frequency resolution can be adjusted according to the different parts of the signal. The discrete wavelet transform (DWT) is a fast and discretized implementation for classical WT. Due to the aliasing, lack of directionality and shift-variance disadvantages, the DWT exhibits limited performance in the process of BSs. In literature, an improved version of the DWT, which is named as Dual Tree Complex Wavelet Transform (DTCWT), is employed in the analysis of BSs with great success. In this study, considering the improvements in embedded system technology and the needs for wavelet based real-time feature extraction or de-noising systems in portable medical devices, the DTCWT is implemented as a sub-system in field programmable gate arrays. In proposed hardware architecture, for every data input-channel, DTCWT is implemented by using only one adder and one multiplier. Additionally, considering the multi-channel outputs of biomedical data acquisition systems, this architecture is designed with the capability of running in parallel for N channels.","PeriodicalId":422807,"journal":{"name":"2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127568343","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}
