Consequently, it is very important to diagnose AD in its early stages. This diagnosis is required using different methods through certain alternative approaches. Different techniques such as imaging, clinical, genetic, and fluid biomarker-based pattern classification methods are used for developing predictive models of AD dementia. In this paper, two approaches are used to recognize the prognostic and diagnostic biomarkers that can discriminate between AD and non-AD patients. The publicly available microarray of gene expression datasets from six brain regions are used. The first approach is used to explore the biomarker gene in each region of the six brain regions and in turns investigate the best region that used for AD identification. The second approach is to create the gene network based on extracting the most significant gene in each region separately and extract the hub one of each network. Then, hub genes in each region are used in a classification step to investigate the efficiency of such genes in recognizing AD patients.The highest 50 genes from each region were used in both approaches. In the classification step, the feature selection based on T-test followed by the Support Vector Machine (SVM) classifier is used. Experimental results show reliability of SVM with this kind of gene expression data. The first approach yields best classification results with Entorhinal Cortex (EC) region reaching 95.7%. The second approach proves that hub genes are more efficient in identification of AD improving the classification accuracy with all brain regions reaching 100% accuracy for EC region.","PeriodicalId":231431,"journal":{"name":"2021 38th National Radio Science Conference (NRSC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133551039","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 need to extract the cell response under the effect of the electric stimulus pulse. This response can be an indication to know how we define the appropriate conditions for electroporation the selected cell. The electroporation considers avital source for the drug delivery and therapeutical method. So, we represent a mathematical model can define white blood cell response. The study target to show suitable and the appropriate conditions for the electric stimulus signal to communicate with normal and malignant cells. The electroporation modelling in this study focuses on two main critical features to differentiate between the different categories of white blood cells. The two main selected features are the cell membrane potential and analysis for the density of the pores as function in the applied the electric field. To enhance the study, we add more features such as the charging time and settle voltage. This mathematical model used to represent a solution for Laplace’s formula for the electric field potential, and the formula for the concentrations of the pores using COMSOL Multiphysics.","PeriodicalId":231431,"journal":{"name":"2021 38th National Radio Science Conference (NRSC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133023774","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 suggested antenna generates six resonance frequencies to cover 3.965 GHz (WiMAX), 7GHz, 9.188GHz (ultra-wideband, satellite)11.664GHz (space program application), 12.956GHz (indoor high-data-rate application) and 13.861 (land mobile satellite, radio navigation application) that cover the range from 2 to 17 GHz. The suggested antenna contains five rectangular slots based upon the defected ground structure (DGS) under the transmission line feed. The middle rectangular slot works as a mirror that reflects the image of the second rectangular slot. The third slot and all the rectangular slots have the same width, whereas the top side of the suggested antenna contains three rectangular strips as patch antennas based on defected microstrip structure (DMS). The suggested antenna is designed by a simulator that depends on the finite element method (FEM). The suggested antenna is printed and fabricated on double-sided substrate material that is 1.524 mm thick with an area of 45 × 40 mm2. The simulation and measurement results prove that the suggested antenna has good input impedance bandwidths as S11 ≤ −10 dB at six operating frequencies. The measurement results display good agreements with simulation results. For study purposes, we analyze the suggested antenna and simulated results compared on bandwidth, gain, efficiency, and return loss. The resultant antenna with mirror stairs shape based on DGS and DMS has improved in parameter performance mostly enhancement in bandwidth.","PeriodicalId":231431,"journal":{"name":"2021 38th National Radio Science Conference (NRSC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117138629","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}
