Development, Validation, And Comparative Evaluation Of A Rheotaxis-Based Microfluidic Device To Isolate A Subpopulation Of High-Performance Human Spermatozoa, Charlene S. Fournier

Electronic Theses and Dissertations 2020 - Present

Fertility has declined over the past decades, and male infertility is now recognized as contributing equally to the need for Assisted Reproductive Technologies (ART). Current clinical sperm processing methods rely on multiple centrifugation steps, which are time- and labor-intensive and may be detrimental to spermatozoa. Therefore, improved methodologies are needed to select functional, healthy spermatozoa while mimicking natural sperm selection. Microfluidics has expanded in reproductive biology and offers an efficient approach to selecting spermatozoa based on progressive motility and rheotaxis—their natural ability to swim against a constant flow. In this study, I developed a rheotaxis-based microfluidic device to isolate highly …

‘Ad Majorem Dei Gloriam’: The Religious And Political Missions Of The American-Catholic Military Chaplaincy During The Mexican-American War, Daniel Thomas Louis Moore

Doctoral Dissertations and Projects

The historical community has neglected to deeply analyze the American-Catholic military chaplaincy in the Mexican-American War, 1846-1848. With exceptions, most historians, who have discussed this chaplaincy, have run the spectrum of dedicating an entire chapter to a few sentences on it. “‘Ad Majorem Dei Gloriam’” offers a first, in-depth monograph of this chaplaincy. “‘Ad Majorem Dei Gloriam’” argues that the political mission from President James K. Polk to the chaplaincy, which was to help reconcile Americans and Mexicans, did not truly suffer the failure or the mediocrity that certain historians have portrayed it to be. Instead of analyzing the chaplaincy’s …

A Phenomenological Approach To Exploring Emotional Dysregulation And Lack Of Empathy In Preschoolers From Low Income Christian And Non-Christian Families, Christine Mendez

Doctoral Dissertations and Projects

Children often apply the adaptive skills they learn at home to the classroom in preschool, marking their first experience in structured environments. Two constructs, emotional regulation and empathy, are behaviors necessary for a preschooler’s development. However, the absence of socially desirable contexts can lead to preschoolers developing academic and behavioral deficits. Existing literature does not explore the spiritual, social and cultural practices of the familial and academic environments of preschoolers from disadvantaged groups. Earlier studies from higher socioeconomic levels suggest that poor attachment during infancy, parenting skills, trauma or lack of age-appropriate learning opportunities are conditions that deteriorate regulation and …

Ai Method For Classification Of Diagnosis Of Near-Infrared Breast Lesion Images, Kaiquan Chen, Fangyang Shen, Honggang Wang, Zhengchao Dong, Jizhong Xiao, Ming Ma, Afroza Aktar, Christopher Chow, Wenxiong Zhang

Publications and Research

In near-infrared optical breast lesion screening and diagnosis systems, high-speed four-dimensional scanners can dynamically acquire tens of thousands of lesion images within a five-minute period. Currently, manual computer annotation is required to generate standard samples from these scanned breast lesion images, a process that depends heavily on physicians with clinical expertise. On average, a single physician can annotate only approximately ten samples per working day. As a result, this process is time-consuming and labor-intensive, and the collected samples often suffer from low accuracy, large variability, and limited diagnostic reliability. Several AI-based annotation tools, such as QuPath, HALO AI™, and X-AnyLabeling, …
