Approximate Decryption In Homomorphic Division And Privacy Impact, Ameerah Alsulami, Marius Silaghi

Electrical Engineering and Computer Science Faculty Publications

The result of a computation over secret inputs inherently reveals some information about those inputs; such semantic leakage is unavoidable. The challenge is to ensure that the computation method does not introduce additional, avoidable disclosure beyond what is implied by the output itself. This issue is particularly critical in privacy-preserving machine learning and cloud-based data processing, where homomorphic encryption enables computation over encrypted data but often relies on practical approximations. Division-enabled homomorphic encryption schemes based on rational encodings preserve arithmetic correctness, but their decrypted outputs may retain sufficient algebraic structure to enable inference of the original operands, creating representation-induced leakage. …

Counting Constraints In Pomdps Based On Pid Controllers, Garrett Gmeiner, Patrick Quinn, Asmaa Alqurashi, Prem Swaroop Pochiraju, Mirajul Islam, Jackson Contreras, Sajina Pathak, Rwaida Alssadi, Sumana Boyapalli, Raghavendra Mallesha, Vijay Uppalapati, Javier Laboy-Jusino, Nikiraj Konwar, Muntaser Syed, Marius Silaghi

Electrical Engineering and Computer Science Faculty Publications

A Bayesian architecture is proposed for integrating counting constraints in the process of decision making with Partially Observable Markov Decision Models for robotics. In addressed problems, the counted events are detected with noisy sensors, making their detection uncertain. We handle their count as a random variable to be updated on observations. In our test scenario, an iRobot Create3 moves along a hallway and needs to count how many doors it passes while following the wall. After detecting that the given number of doors have been passed, the robot should turn around and return to the starting region. For this kind …

Preoperative Patient Sentiment Is Associated With Postoperative Outcomes In Adult Spinal Deformity Surgery, Ross J. Gore, David Mazur-Hart, Mohan K. Sunkara, Aaqib Ali, Qizar Ali, Christopher J. Lynch

Center for Secure and Intelligent Critical Systems (CSICS) Publications

Study Design:

Prospective observational pilot study of adult spinal deformity surgery patients.

Objective:

To determine whether preoperative patient sentiment, quantified using a 21-class valence scale extending the CARP paradigm implemented through an offline Large Language Model, predicts postoperative outcomes.

Summary of Background Data:

Predicting adult spinal deformity surgery outcomes remains challenging with traditional clinical and radiographic parameters alone. Although patient psychological factors and expectations significantly influence postoperative satisfaction and quality of life, systematic approaches to capture these factors are underdeveloped. Offline Large Language Models offer scalable, privacy-preserving psychological risk stratification.

Materials and Methods:

We prospectively enrolled 18 patients undergoing adult …

Adaptive Boundary-Aware Fact-Checker Placement For Misinformation Suppression In Social Networks, Mostafa Taghizade Firouzjaee, Ghazal Naderi, Ross Gore, Neda Moghim

School of Cybersecurity Faculty Publications

The spread of fake news on online social networks is driven by imitation-based user behavior and network topology, often leading to persistent misinformation clusters and echo chambers. In this study, we develop a spatial evolutionary game-theoretic framework in which agents update their latent opinions through payoff-biased imitation, while external fact-checkers act as non-imitative intervention nodes. Building on this formulation, we propose an adaptive, boundary-aware intervention mechanism that dynamically regulates both the density and spatial allocation of fact-checkers according to real-time system conditions. Competing information clusters are identified through local neighborhood composition, enabling boundary nodes, i.e., interfaces between fake-news and non-fake-news …

Rebuilding Participation: Trauma-Informed Support For At-Risk Teens, Emily A. Funk

Occupational Therapy Capstones

Background: Over half of our youth population have experienced at least one adverse childhood experience (ACE) before they reach adulthood (Madigan et al., 2025). ACEs are major factors in increasing a child’s chances of making risky lifestyle choices that negatively affect their physical, emotional, and mental health (Atchison & Suarez, 2021; Felitti et al., 1998). Dysregulation, irrational behaviors, poor academic achievements, high levels of stress, and feeling a loss of purpose are some of the challenges that at-risk youth face (Atchison & Suarez, 2021).

Purpose: The purpose of this scholarly project is to develop a toolkit that contains indirect occupational …

Quality Of Life Of Individuals Residing In Senior Living Facilities, Meagan R. Danda

Occupational Therapy Capstones

Introduction: Formal caregivers play an essential role in supporting residents’ physical, emotional, and social needs which contribute to overall health and well-being (Spilsbury et al., 2024). Due to these responsibilities, caregivers need to be properly equipped with the knowledge and skills necessary to perform clinical duties with confidence. The purpose of this scholarly project is to develop a product that increases caregiver confidence by providing caregivers with occupational therapy informed education. By enhancing caregivers’ knowledge and skill set, this product may contribute to a supportive environment that fosters resident engagement in meaningful occupations and promotes improved quality of life (QoL) …

Sport Training Day Affects Adolescent Athletes’ Sleep Schedules, Abigail Larson, Jena Heck Street, Roman De Guia, Jacob J. Capin

Physical Therapy Faculty Research and Publications

Introduction: Sufficient sleep is integral to overall health whereas suboptimal sleep puts athletes at greater risk for injury, lengthens their recovery time, and decreases their performance. Our purpose was to compare sleep across training days (i.e., competition, practice, and rest) in adolescent athletes, specifically identifying differences between nights before and after training.

Methods: Participants [n = 33 (14 male, 19 female), aged 15.6 ± 1.0 years] wore an activPAL accelerometer continuously for 14 consecutive days and completed a sleep log noting training day status (i.e., competition, practice, rest).

Results: Athletes slept less on the day after competition compared to …

Improving Efficiency In Noma Schemes Having Inter-User Interference Using Mechanism Design, Zory Marantz

Publications and Research

Modern wireless systems utilize non-orthogonal multiple access to increase their rate capacities; however, the efficiency of the individual utility defined in bits per Joule has yet to be considered. Multiple variations of non-orthogonal multiple access have the interference of the signal-to-interference-plus-noise ratio as a function of the received power from multiple other users due to code implementations that are non-orthogonal or non-ideal cancellation in successive-interference-cancellation methods. Game theoretic concepts are used to improve user bits-per-Joule performance. Previous solutions increment transmit power and are not based on closed form systematic methods. The mechanism design presented here led to a non-cooperative Nash …

Muinji’J Asks Why (2022) By Shanika Maceachern And Breighlynn Maceachern, Maughn Rollins Gregory

Picture Books

In the nineteenth and twentieth centuries American and Canadian government agencies and Christian churches established Indian residential schools where hundreds of thousands of children were “reeducated” in English and Christianity. They were not allowed to use their native languages or given names, to practice their religions, or to communicate with their siblings or parents. They were made to work in crop fields, kitchens, laundries, and industrial workshops. Many were physically and sexually abused. Many never saw their families again. The nine picture books reviewed here are accounts of survivors of residential schools from eight different Indigenous nations. In addition to …

Thinkmatter: Panoramic-Aware Instructional Semantics For Monocular Vision-And-Language Navigation, Guangzhao Dai, Shuo Wang, Hao Zhao, Bin Zhu, Qianru Sun, Xiangbo Shu

Research Collection School Of Computing and Information Systems

Vision-and-Language Navigation in continuous environments (VLN-CE) requires an embodied robot to navigate the target destination following the natural language instruction. Most existing methods use panoramic RGB-D cameras for 360° observation of environments. However, these methods struggle in real-world applications because of the higher cost of panoramic RGB-D cameras. This paper studies a low-cost and practical VLN-CE setting, e.g., using monocular cameras of limited field of view, which means “Look Less” for visual observations and environment semantics. In this paper, we propose a ThinkMatter framework for monocular VLN-CE, where we motivate monocular robots to “Think More” by 1) generating novel views …

Memoryart: Enhancing Llms Via Multi-Memory Models With Adaptive Resonance Theory For Healthcare Agents, Renke Dai, Hebin Hu, Jiahui Zhang, Yilin Kang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Though promising in healthcare consultation applications, large language models (LLMs) face critical limitations in retaining and utilizing long-term memory across multiturn interactions. In particular, existing memory enhancing paradigms are constrained by limited context windows and embedding-based retrieval, often failing to maintain task relevance and still suffering from memory prototype collapse in multi-turn healthcare consultation. To address these challenges, we propose a cognitively-inspired memory framework named MemoryART, which is grounded in Adaptive Resonance Theory (ART)—a cognitive and learning theory of how humans and animals adapt to dynamic environments. MemoryART employs three memory modules—working memory, episodic memory, and semantic memory to support …

Clique Annealing: Semi-Supervised Community Detection Under Crystallization Kinetics, Ling Cheng, Jiashu Pu, Ruicheng Liang, Qian Shao, Hezhe Qiao, Feida Zhu

Research Collection School Of Computing and Information Systems

Semi-supervised community detection seeks to find a specified community type when only few communities are labeled. Existing "select-then-refine" pipelines often start from mis-aligned cores and rely on Reinforcement-Learning or Generative Adversarial Network, increasing computational cost and limiting scalability. We address these issues with a unified energy framework under crystallization kinetics that jointly models energy, structure, and growth. Based on this perspective, we propose CLique ANNealing (CLANN), which first employs Nucleus Proposer to select candidate clique as community core under four physics-inspired criteria. A learning-free Transitive Annealer then iteratively merges neighboring cliques and repositions the nucleus, enabling spontaneous, scalable community growth. …

Prosocial Ceos And Accounting Manipulation, Mei Feng, Weili Ge, Zhejia Ling, Wei Ting Loh

Research Collection School Of Accountancy

This paper examines the association between chief executive officers’ (CEOs’) prosocial tendency and their firms’ likelihood of accounting manipulation. We measure CEOs’ prosocial tendency based on their involvement with charitable organizations. We find that prosocial CEOs are less likely to engage in accounting manipulation, as proxied by material non-reliance restatements and SEC or DOJ enforcement actions. The effect is more pronounced when CEOs are involved with charities that directly aim to improve the welfare of others and when they face stronger incentives to misreport. These results continue to hold in analyses of changes in CEOs’ prosocial tendency around turnover events. …

Intermittent High-Fat, High-Sugar Access During Adolescence Drives Binge-Restriction Feeding And Reduced Weight Gain In A Food Unpredictability Model, Calvin G. Miller

CMC Senior Theses

Food insecurity affects nearly 48 million Americans and 318 million people worldwide, with very low food security disrupting normal eating habits through “feast-or-famine” episodes characterized by cycles of food overconsumption followed by restriction. This dietary pattern alters dopamine signaling within the mesocorticolimbic system — brain circuitry intimately linked to reward processing. This system includes the ventral tegmental area (VTA) and prefrontal cortex (PFC). Overstimulation can be promoted through sporadic high-fat, high-sugar diet (HFHSD) exposure, promoting dopamine neuron architecture alterations and binge-eating behavior. Adolescence represents a vulnerable window, as mesocorticolimbic dopamine projections undergo maturation during this period. Though evidence links food …

Adolescent Binge-Like Feeding And Neuroinflammation: Effects Of Intermittent Palatable Diet Access On Microglial Activation In The Brain In Adolescents, Jaimie T. Yu

CMC Senior Theses

Binge eating disorder (BED), one of the most common eating disorders in the United States (Definition & Facts for Binge Eating Disorder - NIDDK, n.d.), is characterized by recurrent episodes of consuming large quantities of food in a short period of time accompanied by a sense of loss of control. The intermittent access (INT) model reliably produces binge-like eating in adult rodents, with animals showing episodic hyperphagia upon time-limited access to a high-fat, high-sugar (HFHS) diet. In adult female rats, INT access produces elevated meal size and reduced satiety ratio relative to controls (Maske et al., 2020), and promotes microglial …

Volatility Modeling With An Application To Risk Parity Portfolios, Kenneth Hou

CMC Senior Theses

This thesis studies volatility modeling in the context of risk parity portfolio construction. I compare three risk parity portfolios that differ only in their underlying volatility model: a historical covariance baseline, a Bayesian stochastic volatility model, and a GRU–GARCH hybrid neural network. Using daily returns on Kenneth French’s five industry portfolios from January 2016 through December 2025, I construct monthly rebalanced portfolios under each model, with the SV and GRU forecasts embedded in hybrid covariance matrices that combine forecasted volatilities with rolling historical correlations. The results document a divergence between forecast accuracy and portfolio performance: the SV model is the …

Hidden Fragility: Leveraged Loan Risk And Tail Exposure In The Clo 2.0 Era, Francis P. Gehring Iv

CMC Senior Theses

This thesis examines whether post-crisis changes in leveraged loan characteristics have increased the underlying credit risk embedded in collateralized loan obligation (CLO) portfolios and whether that risk is fully reflected in market pricing. Since the Global Financial Crisis, the leveraged loan market has expanded significantly alongside the growth of CLOs, while underwriting standards have weakened through higher borrower leverage, covenant-lite lending, and greater private equity sponsorship. Although post-crisis CLOs are often viewed as more resilient because of stronger structural protections, the quality of the underlying collateral remains central to overall risk. Using loan-level data from the Refinitiv DealScan database from …

Morals Without Movement: Veganism, Contentious Politics, And The Lifestyle Politics Constraint, Luke M. Carfaro

CMC Senior Theses

This thesis examines whether veganism constitutes a social movement through Social Movement Theory frameworks, emphasizing Sidney Tarrow's Power in Movement. Through analysis of veganism's empirical properties (collective challenge, common purpose, collective identity, and sustained interaction) and key procedural mechanisms (framing, mobilizing structures, and repertoires of contention), this thesis determines that veganism fails to meet the empirical criteria of a social movement and is more accurately classified as a lifestyle movement—a movement in which political participation is expressed through private consumption rather than sustained collective contention. Using the Make America Healthy Again movement as a counterexample, this thesis comparatively illustrates …

Rank Rebalancing In Commodity And Foreign Exchange Markets, Prateek D. Vyas

CMC Senior Theses

This thesis empirically tests the rank-rebalancing mechanism of Stochastic Portfolio Theory (SPT) across commodity futures, foreign exchange futures, and equity ETFs. The Reverse Price-Weighted strategy (RPW) assigns, to each asset, the market weight of the asset at the opposite price rank, and generates an annualized excess return of 2.90% over the price-weighted (MKT) commodity benchmark, during the period of November 1977 to October 2025 (HAC t = 2.058, p = 0.040). The differential Sharpe ratio (dSharpe) of 0.245 is confirmed by a stationary block bootstrap, with a 𝑝-value of 0.015, and factor regressions controlling for carry, momentum, and value yield …

Bitcoin And The American Conflict Over Money And Property, Jacob Smagula

CMC Senior Theses

I argue that Bitcoin is the latest expression of the recurring American conflict over who controls the terms of money and property, and that the political coalition formed around Bitcoin shares the same characteristics as earlier coalitions formed around this struggle. I review three historical cases that each produced a coalition opposing the existing monetary order: the Bank War of the 1830s, the Free Silver movement of the 1890s, and the populist backlash against the Federal Reserve during the 1979 Farm Crisis and the 2008 Great Recession. I find that Bitcoin’s architecture, which allows for self-custody, permissionless access, and an …

More Than A Lawyer: Participation, Representation, And Outcomes In Los Angeles Debt Collection Court, Josephine V. Aspromonte

CMC Senior Theses

This paper estimates the effect of legal representation on case outcomes using 531,959 limited-jurisdiction debt-collection cases filed in the Los Angeles Superior Court between 2012 and 2022. Defendants are classified into three groups: those who defaulted without responding, those who responded pro se, and those who retained counsel. Because defendants are not randomly assigned to representation, three estimation strategies address selection bias: a binary logit, a multinomial logit with text-mined docket covariates, and propensity score matching on pre-treatment characteristics.Three findings emerge. First, the binary logit associates representation with a 10 to 13 percentage point reduction in default probability, but matching …

From Governed To Subjected: The Supreme Court And The Collapse Of Rule-Of-Law Adjudication, Katherine E. Schwab

CMC Senior Theses

This thesis argues that the Supreme Court is producing a structural crisis in rule-of-law adjudication through three converging mechanisms: the expanded use of the shadow docket, the cynical appropriation of precedent, and the dominance of strict originalism. Each independently undermines the conditions that distinguish legitimate governance from the mere exercise of coercive power. Together, they replace the general, stable, publicly intelligible norms the rule of law requires with the successive pronouncements of whoever currently holds interpretive power.

The thesis develops its argument in three stages. First, drawing on Antonin Scalia's account of rule-like precedent and Jeremy Waldron's layered theory of …

A New Playbook: The Procedural Resilience Of Oregon’S Rooney Rule In The Wake Of Students For Fair Admissions V. Harvard, Jada I. Cook

CMC Senior Theses

This article evaluates the constitutionality of Oregon’s codified Rooney Rule considering the Supreme Court’s decision to end affirmative action in Students for Fair Admissions (SFFA) v. Harvard. Passed in 2009, the Oregon mandate requires public universities to include at least one minority applicant in the interview process for all head coaching vacancies. By analyzing the architectural origins of the Rooney Rule within the National Football League (NFL) and the systemic racial exclusion it sought to dismantle, this research explores whether interview-stage mandates, that are applied at the state level, can survive the rigorous application of the strict scrutiny standard. …

Microbial Community Structure In Global Soils, Matthew Jabro

CMC Senior Theses

Soil harbors the most diverse microbial communities on Earth, yet whether predictable community types exist across biomes and whether taxonomic composition encodes habitat of origin remain open questions at global scale. This thesis addresses both questions by applying unsupervised clustering and supervised classification to transformed 16S ribosomal RNA (rRNA) amplicon profiles from two independent datasets: the global topsoil survey of Bahram et al. (193 samples) and the Earth Microbiome Project (EMP) soil subset of Thompson et al. (2,209 samples). Application of a sample clustering method based on a mixture of Gaussian Graphical Models (MixGGM) identified 19 clusters in the topsoil …

Prediction Markets Vs. Sportsbooks: A Comparison Of Nfl Forecast Accuracy, Dylan Cotti

CMC Senior Theses

This paper compares the forecast accuracy of Kalshi, a prediction market, and DraftKings, a sportsbook, using data from 285 NFL games in the 2025-26 season. I collect win probabilities from both platforms at three time points in the week before each game and measure accuracy using the Brier score. I find that Kalshi produces slightly more accurate predictions than DraftKings, but the gap is small and marginally significant. More surprisingly, both platforms become less accurate as the game approaches rather than more accurate. Once I control for differences in how each platform distributes its quoted probabilities, the accuracy gap largely …

Why Dining Out Stayed Cheap In Japan, Taketo Hayashi

CMC Senior Theses

This thesis examines why food-away-from-home inflation in Japan was persistently lower than in the United States from 1995 to 2021 and why this dynamic changed after 2021 during the COVID-19 pandemic. Two structural buffers sustained the divergence: wage stagnation in Japan, which kept restaurant labor costs flat for nearly three decades, and a strong yen, which absorbed global commodity price shocks before they could reach restaurant menus. In 2008, the financial crisis sent food and energy prices skyrocketing. However, even though Japan imports most of its food and energy, the effects from global price increases were due to a strong …

Rethinking Reentry In The United States: A Comparative Analysis Of Incarceration Strategies In Norway, Singapore, And Austria, Amelia Ulmer

CMC Senior Theses

The prison reentry system in the United States remains a pressing social, economic, and political issue, as hundreds of thousands of prisoners are released each year with few resources to assist them with their transition. In fact, these previously incarcerated people are arguably set up to fail, which leads to over half of them reoffending within two years. This thesis analyzes how the United States should reform its current prison system based on lessons learned from three international case studies. These three case studies, Norway, Singapore, and Austria were chosen as countries that have globally low recidivism rates and unique …

Procedural Rhetoric And Prosociality: How Game Mechanics Shape Altruistic Decision-Making, Elijah Emory-Muhammad

CMC Senior Theses

This study investigates how different prosocial video game designs influence subsequent altruistic behavior, specifically comparing interactive narratives with procedural rhetoric. While prior research demonstrates that prosocial games can prime helpful behaviors, less is known about the underlying mechanical structures driving these effects. Fifteen participants engaged with either an Interactive Narrative Game (ING) or a Procedural Rhetoric Game (PRG) before completing a resource allocation task (Dictator Game). Results revealed no statistically significant differences between the two conditions in promoting sacrificial altruism or satisfying basic psychological needs. Instead, participants across both groups demonstrated a strong adherence to an equality-seeking norm, consistently choosing …
