SGR: Validating the Optimal Design of Concentric Ring Electrodes on Phantom Data

部落学院和大学方案(TCUP)的一个目标是提高为本国土著学生服务的特定高等教育机构的科学、技术、工程和数学(STEM)教学和研究能力。扩大这些机构的研究能力增加了学生在STEM领域追求具有挑战性的、有回报的职业的机会，提供了可能与当地相关的领域的研究性学习，并鼓励教师群体将目光投向传统课堂之外的智力和专业成长。该项目与这一目标直接一致，而且可能被证明是其他小型社区大学类似参与的模型。该项目寻求在真实的体模模型数据上验证最优三极同心环电极(CRE)配置的物理原型。此外，它还试图调查物理CRES记录面之间的盐桥缩短对拉普拉斯估计可能产生的不利影响。对这一新兴的非侵入性电生理诊断技术的研究有可能促进人们对脑电(EEG)和心电(EKG)等系统中拉普拉斯估计的认识和准确性。该项目旨在提高信号的诊断产量，为不成比例地影响美洲原住民人口的情况使用最佳的CRES。此外，该项目加强了迪内学院工程应用数学实验室的能力，同时为部落大学生提供参与尖端合作国际研究的机会。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

A goal of the Tribal Colleges and Universities Program (TCUP) is to increase the science, technology, engineering and mathematics (STEM) instructional and research capacities of specific institutions of higher education that serve the Nation's indigenous students. Expanding the research capacity at these institutions increases the opportunities for students to pursue challenging, rewarding careers in STEM fields, provides for research studies in areas that may be locally relevant, and encourages a faculty community to look beyond the traditional classroom for intellectual and professional growth. This project aligns directly with that goal, and moreover may prove to be a model for similar engagement at other small community colleges.This project seeks to validate the physical prototypes of optimal tripolar concentric ring electrode (CRE) configuration on real life phantom model data. Moreover, it seeks to investigate possible adverse effects of salt bridge shortening between the recording surfaces of physical CREs on Laplacian estimation. Study of this emerging, noninvasive electrophysiological diagnostic technology has the potential to advance knowledge and improve the accuracy of Laplacian estimation in systems such as electroencephalograms (EEG) and electrocardiograms (EKG). The project aims to improve the diagnostic yield of signals using optimal CREs for conditions that disproportionately affect Native American populations. Furthermore, the project strengthens the capacity of the Mathematics for Engineering Applications lab at Diné College, while providing opportunities for tribal college students to participate in cutting edge collaborative international research.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
