Strategies For Extending The Service Life Of Prestressed Concrete I-Shaped Beams, Sanjoy Kumar Bhowmik

Dissertations

Prestressed concrete (PSC) I-shaped beams are widely used in bridge construction because of their structural efficiency and durability. The service life of these beams is reduced and the maintenance frequency is increased due to the distress during fabrication and subsequent deterioration. Although several mitigation strategies have been proposed and implemented, beam end cracking during fabrication remains a major concern. The causes and mitigation strategies for beam end cracking have been studied for decades, but there have been no comprehensive studies utilizing beam end strains during fabrication and lifting at prefabrication plants under normal operational conditions. Moreover, existing maintenance and repair …

Deployment-Aware Deep Learning For Computer Vision: Efficient Architectures From 3d Segmentation To Mixed Reality, Bahar Uddin Mahmud

Dissertations

Deep learning has become the dominant approach for solving vision-centric problems; however, its successful deployment in real-world applications remains limited by high computational cost, data dependency, and insufficient integration with practical and human-centered environments. While state-of-the art deep learning models often achieve impressive performance in controlled settings, they frequently fail to generalize or operate efficiently under deployment constraints such as limited resources, complex data modalities, and real-time interaction requirements. These limitations motivate the need for a deployment-oriented deep learning framework that balances accuracy, efficiency, and practical usability.

This dissertation investigates the design and deployment of efficient deep learning architectures for …

Public Preferences For Critical Mineral Mining In The U.S.: Evidence From A Discrete Choice Experiment, Bamidele Ajiga, Kwame Awuah-Offei, Mahelet G. Fikru

Mining Engineering Faculty Research & Creative Works

Even though there is widespread recognition that we need to mine more critical minerals for national security and energy needs, concerns about environmental impacts often lead to public opposition to proposed new mining projects. The literature lacks sufficient data from communities with proposed mineral projects to assess drivers of differences in support. This study investigates public preferences for mining projects in three states in the United States with proposed critical minerals projects, using a discrete choice experiment. Respondents evaluated projects that vary in job creation, state tax revenue, tailings reprocessing content, groundwater impacts, and surface water impacts. We also randomly …

Real Promise For False Claims: A Whistleblower Litigation Strategy To Reward Investigative Journalism, Frank D. Lomonte

Washington Law Review

Every year, investigative reporters uncover stories of waste, fraud, and corruption, alerting the government to taxpayer ripoffs that had previously gone undiscovered or ignored. For decades, non-journalists have been reaping windfall rewards—sometimes in the millions—by using false-claims statutes to bring whistleblower actions on the government’s behalf. With news organizations struggling for their economic survival, and efforts to secure alternative financial support through government bailouts faltering, is it time for journalists to seek a share of the money they recoup for taxpayers by becoming plaintiffs?

This Article explores the possibilities, and downside risks, of using the federal False Claims Act, and …

Standardizing Tms Intensity Across Different Coils Using Individualized Electric Field Modeling, Evgenii Kim, Mohammad Daneshzand, Keren Zhu, Danyal Fareed Bhutto, Teresa Jacobson Kimberley, Dylan J. Edwards, Netri Pajankar, Parker Kotlarz, Tommi Raij, Sergey N. Makaroff, Aapo Nummenmaa

Moss-Magee Rehabilitation Papers

Quantitative measures for Transcranial Magnetic Stimulation (TMS) intensity are needed to ensure safe and consistent application in therapeutic and research settings. However, resting motor thresholds (rMTs), commonly used to determine stimulation intensity, depend on the coil used. Unless motor mapping and treatment coils are identical, re-thresholding is necessary, increasing patient discomfort and potentially introducing variability across studies. These considerations raise an unresolved fundamental question: does individual rMT reflect a consistent cortical electric field (E-field) magnitude independent of coil geometry? We tested the hypothesis that rMT corresponds to a coil-invariant cortical E-field magnitude and evaluated a computational method for predicting stimulator …

Prompted Props, Human Pipelines: Evaluating Ai-Generated 3d Assets For Game-Ready Environments, Andrew Begemann, James Hutson

Decentralizing Dementia Research To The Us–Mexico Border: The Rio Grande Valley Ad-Rcmar As A Model For Translational Equity, Gladys E. Maestre, John Blangero, Eron Manusov, Gabriel A. De Erausquin, Francisco Fernandez, Silvia Mejia-Arango, Vincent P. Diego, Juan C. Lopez-Alvarenga, Claudia Alaniz, Neyra García, Rosa V. Pirela, Andrew Tsin, Michael Mahaney

School of Medicine Publications

Translational equity means ensuring that diagnostics, treatments, care models, and prevention strategies are developed and implemented so they work for populations with the greatest burden and least access to care. In Alzheimer's disease and related dementias (ADRD), where most evidence derives from highly educated, non-Hispanic White participants at large academic centers, translational equity is critical to prevent misclassification, limited access, and widening disparities and to ensure that underrepresented communities shape how new knowledge moves into practice. Hispanic and other populations in the United States are disproportionately affected by ADRD yet remain underrepresented in research, with gaps especially pronounced in high-poverty …

Generation And Characterization Of Twist1 Acetyl-Mimic And Acetyl-Deficient Mouse Models, Mary Elmeniawi, Xiaobin Yu, Samuel Wen, Gunjan A Bhatia, Lan Liao, Jianming Xu, Walid D Fakhouri

Faculty, Staff and Students Publications

TWIST1 encodes a highly conserved basic helix–loop–helix transcription factor essential for embryonic development from Drosophila to humans. TWIST1 activity is regulated by post‐translational modifications, including phosphorylation during development and cancer metastasis. Recent cancer studies identified acetylation of lysines K73 and K76 as a novel regulatory modification that shifts TWIST1 from a repressive to an activating state during epithelial‐to‐mesenchymal transition (EMT). However, the developmental and in vivo functions of TWIST1 acetylation remain unknown. To investigate the physiological role, we generated the first acetyl‐deficient Twist1 K73,76R K73,76R and acetyl‐mimic Twist1 K73,76Q K73,76Q mouse models using CRISPR/Cas9‐mediated genome editing. Targeted sequencing confirmed substitutions, …

How To … Coach Problem Representation To Strengthen Diagnostic Reasoning In Trainees, Cody Clary, Adam Cohen, Satid Thammasitboon

Faculty, Staff and Students Publications

Problem representation (PR) is a concise synthesis of clinical information that captures the core diagnostic problem in a single statement, often referred to as a 'one-liner'. Although central to diagnostic reasoning, this skill is frequently underdeveloped in medical training. Many trainees struggle to transform clinical data into meaningful representations, which can hinder communication, diagnostic reasoning and patient safety. The Assessment of Reasoning Tool-Reconstructed (ART-R) provides a structured framework that educators can adapt as a coaching rubric to strengthen PR during clinical teaching. Using the ART-R, faculty can guide trainees to refine their PR by focusing on three elements: (1) clarity …

“I Didn’T Know Architects Do This”: Interventions In The Social Reproduction Of The Architect Figure In Ireland., Miriam Delaney

Doctoral

The architect is widely understood as the producer of architectural artefacts: buildings, feasibility studies, drawings, and specifications. However, architects (as a professional collective identity) are themselves produced by the complex matrix of social relations and structural forces in which they act; the architect is as much a product as the architectural artefacts.

This thesis provides a retrospective critical examination of aspects of my work in expanded forms of architectural practice from 2011 to 2021. My Critical Appraisal of this work focuses less on the content or successes of the Outputs, the products of production, and more on their collective contribution …
