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

部落学院和大学计划（TCUP）的一个目标是提高为美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、回报丰厚的职业的机会，为当地相关领域的研究提供了机会，并鼓励教师社区超越传统课堂，寻求智力和专业发展。这个项目直接符合这一目标，而且可能被证明是其他小型社区学院类似参与的典范。本项目旨在验证三极同心圆电极（CRE）配置的物理原型在现实生活中的幻影模型数据。此外，它还试图研究物理cre记录表面之间盐桥缩短对拉普拉斯估计可能产生的不利影响。对这种新兴的、无创的电生理诊断技术的研究有可能在脑电图（EEG）和心电图（EKG）等系统中推进知识和提高拉普拉斯估计的准确性。该项目旨在提高信号的诊断率，使用最优的cre来诊断对美洲土著人口造成不成比例影响的疾病。此外，该项目加强了din<e:1>学院工程应用数学实验室的能力，同时为部落大学生提供了参与尖端国际合作研究的机会。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值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.
