Towards Efficient Privacy-Preserving Deep Learning: He-Friendly Structures, Flexible Pruning, He-Efficient Architectures, And Secure Transformer Token Drop, Yifei Cai

Electrical & Computer Engineering Theses & Dissertations

Deep learning (DL) has become a powerful tool for solving complex problems, but developing DL models typically requires vast datasets, high computational resources, and expert knowledge—barriers that limit accessibility. Machine Learning as a Service (MLaaS) addresses this challenge by allowing resource-rich providers to deliver pre-trained DL models as services. However, privacy concerns arise: clients hesitate to share sensitive data, while providers protect their proprietary models. To address this, privacy-preserving MLaaS integrates cryptographic techniques into DL computations, as seen in frameworks like Cryptonets, SecureML, GAZELLE, CrypTFlow2, Cheetah, and BOLT. Among them, Homomorphic Encryption (HE) enables computation on encrypted data but remains …

Translating The Hba1c Lab Test Name And Results From English To Arabic For Enhanced Patient Access And Workflow Efficiency, Aiman M. Alrawabdeh

Translational Projects (Open Access)

In Jordan, where the healthcare system primarily operates in English, Arabic-speaking patients encounter significant challenges in understanding laboratory test names and results, including Hemoglobin A1c (HbA1c), an essential diagnostic indicator for diabetes management. The lack of multilingual access to medical information limits health literacy and patient autonomy, increasing dependence on healthcare staff for translation assistance. This translational informatics project addressed these challenges by developing and implementing an Arabic translation process for the HbA1c lab test name and results. HbA1c was selected as it is a standard lab test among patients with diabetes in Jordan; nearly 30% of Jordanians had type …

Investigating Environmental And Socioeconomic Contributors To Adult Obesity In The Rio Grande Valley, John Nicholas Cauba, Jihoo Woo, Russel Wiggins, Shizue Mito

School of Medicine Publications

Obesity in the Rio Grande Valley (RGV) of Texas remains a critical public health concern, with rates (46.9%) significantly exceeding those of Texas (36%) and the U.S. (34%) (p < 0.001). This study used 2024 County Health Rankings data to analyze environmental and socioeconomic contributors to obesity across 240 Texas counties, with a population-weighted focus on Hidalgo, Cameron, Starr, and Willacy counties. The RGV exhibited markedly poorer access to exercise, higher rates of physical inactivity, lower Food Environment Index scores (FEI = 4.3 vs. 5.7 in Texas), higher rates of uninsurance, worse patient-to–primary care physician (PCP) ratios (2152:1 vs. Texas 1660:1), and increased preventable hospitalizations. Multiple linear regression identified physical inactivity (β = 0.6, p = 0.01) and access to exercise (β = −0.02, p = 0.02) as significant predictors of obesity. Notably, higher uninsured rates were associated with lower reported obesity, likely due to underdiagnosis in the absence of routine care. These findings emphasize the need for targeted interventions addressing food access, environmental and recreational infrastructure, along with healthcare infrastructure in the RGV, where socioeconomic disadvantage and structural barriers magnify the impact of national obesity trends on the regional level.

Lessons From Mysticism For Healthcare Providers: Health Care As A Space For Intersubjective Encounters Of Care, Micaela Plantinga, Alexandre A. Martins

Theology Faculty Research and Publications

Society’s deep divisions, fueled by individualism, competition, consumerism, rigid ideologies, and limited dialogue, have impacted health care, leading to weakened connections between providers and patients. In the U.S., heavy reliance on medical technology and the rise of AI have further eroded these intersubjective bonds, reducing empathetic engagement in care. To address this challenge, the paper explores insights from Christian mystics Saint Teresa of Avila and Edith Stein. Teresa’s teachings on self-examination and humility, despite her life as a cloistered nun, influenced both her religious order and the broader Church. Meanwhile, Stein’s phenomenological approach emphasized empathy and "suffering with" others, viewing …

The Challenges Of Using Ultrasound To Measure The Trachea: A Brief Report, Helen Newman, Jodi Allen, Madan Narayanan, Nchafatso Obonyo, Nur Syahrunnizar, Karen Hammet, David Parry, Sarah Wallace, Anna-Liisa Sutt, Joseph Osterwalder, Daniel Martin

Peninsula Medical School

BACKGROUND: Tracheostomy is a common procedure in intensive care medicine, involving the insertion of an artificial airway through the front of the neck into the trachea. The size of tracheostomy tube in relation to the trachea is important, influencing clinical outcomes and patient experience. Ultrasound is readily available at the bedside and airway applications have been reported, including airway measurement. However, the presence of air within airway lumina presents challenges to ultrasound and causes artefact. Guidance is lacking on tracheal sonography and measurement.

AIM: to characterize the sonoanatomy of the inner tracheal wall and determine reference points for measuring tracheal …

2020-Current year OA Pubs

The choroid plexus (ChP) regulates cerebrospinal fluid (CSF) composition, providing essential molecular cues for brain development; yet, embryonic ChP secretory mechanisms remain poorly defined. Here we identify apocrine secretion by embryonic ChP epithelial cells as a key regulator of the CSF proteome and neurodevelopment in male and female mice. We demonstrate that the activation of serotonergic 5-HT

Transforming The World With Reparations?, Ingrid Brunk, Monica Hakimi

Faculty Scholarship

Claims for reparations in international law commonly reflect two competing visions--one transformative, the other corrective. The transformative vision looks to reparations to end the long tail of injustices that are associated with large-scale historic harms. The corrective vision is more confined; it focuses on repairing specific, legally cognizable harms and returning the agents or entities involved as closely as possible to the status quo ante. We argue in this Essay that these two visions have distinct conceptual logics, even though they often overlap in practice, and that the transformative vision cannot carry the burdens that are placed on it.

Liquid Power: Myths, Realities, And Policy Responses To Wall Street's Takeover Of Water Markets, Vanessa Casado-Pérez

Faculty Scholarship

In Don Quixote, there is a moment when all the knightly novels are thrown into the fire for their fantastical depictions of chivalry. Yet one book is spared: Tirant lo Blanc. It is saved because, unlike the others, it portrays knights who die in their beds-offering a more realistic depiction of medieval battles. Similarly, Liquid Asset stands out as the book that should be preserved from the extensive body of scholarship on water markets. Many works in this field are influenced by ideological biases that shape their analyses. In contrast, Buzz Thompson's books provides the nuance and balance often lacking …

Beringer, C. M. Ewenz, N. Hinko-Najera, L. B. Hutley, P. Isaac, M. Liddell, W. Meyer, C. E. Moore, J. Cranko Page, R. Silberstein, W. Woodgate

Research outputs 2022 to 2026

Climate change-driven increases in drought risk pose a critical threat to global carbon and water cycles. However, ecosystem-scale responses remain poorly quantified, particularly for severe, multiyear drought events. We addressed this gap by examining ecosystem-scale carbon and water flux sensitivity to the extreme 2018–19 drought in Australia using data from 14 eddy covariance flux sites. The ecosystems span grasslands and semi-arid woodlands to tropical and temperate forests. The driest sites (classed as “grass” and “very dry”) experienced drastic productivity impacts, with a 65% decrease in Gross Primary Productivity (GPP) over 2 years relative to the pre-drought average. However, fluxes in …

Amyloid Accumulation, Brain Atrophy, And Cognitive Decline In Emergent Alzheimer's Disease, Ying Xia, Pierrick Bourgeat, Vincent Doré, Jurgen Fripp, Yen Ying Lim, Simon M. Laws, Christopher Fowler, Christopher C. Rowe, Colin L. Masters, Elizabeth J. Coulson, Paul Maruff

Research outputs 2022 to 2026

Introduction : Emergent Alzheimer's disease (AD) represents a transitional stage where cognitively unimpaired (CU) individuals exhibit subthreshold but increasing amyloid-β (Aβ) levels. The impact of Aβ accumulation on brain volume loss and cognition during this early stage remains unclear. Methods: This retrospective cohort study analyzed data from 408 CU participants who were initially Aβ− (< 15 Centiloids) and followed for up to 15 years. Changes in basal forebrain and hippocampal volume, along with domain-specific cognitive performance, were compared between those who progressed to Aβ+ (≥20 Centiloids) and those who remained Aβ−. Results: Sixty-five CU participants progressed to Aβ+, indicating emergent AD, and showed faster Aβ accumulation and subtle memory decline. However, no significant differences in rate of BF and hippocampal atrophy were observed between groups. Discussion: The results suggest that during this emergent phase of AD, Aβ accumulation is associated with episodic memory loss, in the absence of detectable accelerated brain atrophy. Highlights: Identified cognitively unimpaired individuals in the emergent stage of Alzheimer's disease (AD). Emergent AD exhibits a greater rate of amyloid-β (Aβ) accumulation. No accelerated volume loss detected in the basal forebrain or hippocampus. Emergent AD is also associated with a subtle decline in memory. Early Aβ accumulation may impair cognitive function before structural atrophy.

Civil Engineering & Construction: Faculty Publications

Disposal of food waste (FW) in landfills remains an unsustainable practice for organic waste management. Simultaneously, pulp and paper mills produce significant amounts of recalcitrant organic waste that is difficult to decompose due to its high lignocellulosic content. In this study, we developed an innovative approach to improve the digestion of pulp and paper mill sludge (PPMS) by amending FW to produce a low chemical oxygen demand (COD) sludge while recovering methane in the process. This codigestion process was evaluated through lab-scale biogas production experiments coupled with a comprehensive economic and environmental sustainability assessment. Biomethane production results revealed that the …
