The Application, Construction, And Validation Of Hidden Markov Model Profiles For Carbonic Anhydrase Enzymes, Samuel F. Kaplan Mar 2026

The Application, Construction, And Validation Of Hidden Markov Model Profiles For Carbonic Anhydrase Enzymes, Samuel F. Kaplan

Master's Theses

Carbonic anhydrases (CAs) catalyze the reversible hydration of CO2 and have evolved independently at least eight times, resulting in structurally distinct enzyme families (α, β, γ, δ, ζ, η, θ, ι). Traditional sequence alignment methods struggle to classify these convergently evolved proteins because their sequential similarity does not reliably indicate functional or evolutionary relationships. Many CA sequences in public databases are annotated generically without family assignments, and prior computational approaches have focused predominantly on the three well characterized families (α, β, γ), leaving the five recently discovered classes without robust classification tools. Family level assignment is often a prerequisite for …


Sea Level Trends Near Critical Levees In The Sacramento-San Joaquin Delta, Reyna Sanchez Gomez Mar 2026

Sea Level Trends Near Critical Levees In The Sacramento-San Joaquin Delta, Reyna Sanchez Gomez

Master's Theses

The Sacramento-San Joaquin Delta (Delta) levee system faces threats from rising sea levels, land subsidence, and deteriorating levees, all of which pose risks to California’s primary surface water supply. The purpose of this thesis is to assess relative sea level rise (RSLR) and estimate the spatially varying factors that influence water levels in the Delta. This thesis extends the work of Baranes et al. (2023) to the period 1975-2022 by appending recently acquired water-level records (1975-1982) to modern datasets (1982-2022) from 10 water-level stations. These water level datasets were digitized, quality-assured, and referenced to a common geodetic datum, as described …


Measurement And Control Of The Oxidation-Reduction Potential And Its Chemical And Sensory Consequences In Wines, William Jordan Wright Mar 2026

Measurement And Control Of The Oxidation-Reduction Potential And Its Chemical And Sensory Consequences In Wines, William Jordan Wright

Master's Theses

The oxidation-reduction potential (ORP) is a measurement thought to reflect the overall ability of a solution to oxidize or reduce substances within that solution. In wine, there is no absolute agreement as to which substances control or dominate the ORP; however, oxygen, ethanol, iron-tartrate and copper-tartrate complexes, and glutathione are suspected to play key roles, while sulfur dioxide and phenolics may act as buffers. Anecdotally, some varieties of Vitis vinifera are prone to oxidation while others are prone to reduction, though the chemical basis of this remains unclear. The following works aim to further elucidate the influence of specific chemical …


Designing For Trust In Chat-Based Question Answering Systems: An Exchange-Based Retrieval Approach, Nathan Mccutchen Mar 2026

Designing For Trust In Chat-Based Question Answering Systems: An Exchange-Based Retrieval Approach, Nathan Mccutchen

Master's Theses

Community chat platforms such as Discord and Slack support spontaneous, collaborative communication but make it difficult to retrieve previously discussed information. As conversations accumulate, valuable exchanges become buried, leading to repeated questions and sustained burden on experienced community members.

This work contributes a set of design requirements for question-answering systems operating over unstructured chat data, a Discord bot prototype implementing those requirements named Echo, and an empirical evaluation of how such a system affects user trust. Rather than encoding discrete question-answer pairs or generating synthetic responses with a language model, Echo indexes conversation topics for semantic retrieval and presents results …


Associations Between Nutrition-Related Chronic Disease And Food Insecurity: Data From The California State University, Elizabeth Ochoa Mar 2026

Associations Between Nutrition-Related Chronic Disease And Food Insecurity: Data From The California State University, Elizabeth Ochoa

Master's Theses

Food insecurity is a growing public health concern consistently associated with elevated rates of nutrition-related chronic disease (NRCD) across the general population. Despite young adulthood being a critical window for dietary pattern formation, this relationship remains minimally explored among college students. This thesis examined associations between food insecurity and NRCD diagnosis, including hypertension, diabetes, hyperlipidemia, and cardiovascular disease, among undergraduate students across the California State University (CSU) system. Cross-sectional data were drawn from the Spring 2021 CSU National College Health Assessment, administered across all 23 campuses. After exclusions, the analytical sample comprised 13,762 students. Bivariate analyses assessed relationships between key …


Women’S Agency And Pleasure (Wap): Toward A Black Feminist Theory Of Sexuality, Jelisa S. Clark, Erica Campbell Mar 2026

Women’S Agency And Pleasure (Wap): Toward A Black Feminist Theory Of Sexuality, Jelisa S. Clark, Erica Campbell

Journal of Research Initiatives

Black feminist theory has identified sexuality as a site of oppression for Black women, however, there has been limited attention to Black women’s pleasure. We suggest that WAP by Cardi B and Meg the Stallion provides a conceptual lens through which Black women's sexuality can be more humanely envisioned. WAP, in the tradition established by Black women in the blues, represents Black feminist theorizing about sexuality. Themes of Cultivating Community and Developing Voice through Self-Definition are central to discussions of Black women's pleasure. In this work, we bridge academic theorizing and Black women's cultural productions to reinvigorate Black feminist theorizing …


Post-Chevron Deference In Asylum Proceedings, Shawn E. Fields Mar 2026

Post-Chevron Deference In Asylum Proceedings, Shawn E. Fields

Cardozo Law Review

The Supreme Court held for four decades that Chevron deference should apply in all immigration proceedings. How, then, will asylum proceedings change in a post-Chevron world? When, and under what circumstances, will courts continue to defer to the findings of immigration judges and the Board of Immigration Appeals (BIA)? And why does it matter? This Article answers those questions.

These issues require urgent examination for three reasons. First, they directly confront an issue pending before the U.S. Supreme Court in Urias-Orellana v. Bondi: Without the protection of Chevron insulating BIA decisions from meaningful judicial review, can certain legal questions like …


Necessity Or Preference? Navigating The Role Of Physical Presence In The Post-Pandemic Workplace, Shelby Wray Mar 2026

Necessity Or Preference? Navigating The Role Of Physical Presence In The Post-Pandemic Workplace, Shelby Wray

Cardozo Law Review

The COVID-19 pandemic fundamentally altered how society conceptualizes the spatial boundaries of the workplace, proving that businesses can operate effectively without requiring employees’ physical presence. As remote work gained legitimacy during the pandemic, longstanding assumptions about where jobs can be performed—and where legal protections apply—have come into question. In particular, the scope of the Americans with Disabilities Act (ADA) has become increasingly hazy, especially regarding when the ADA is triggered outside of the physical workplace.

Currently, there is a circuit split as to whether employees with disabilities are entitled to ADA protections for their commute to work. This Note addresses …


Exploring Adolescent Hearing Aid Usage And Appearance Of Psychiatric Symptoms In Adolescents Using Hearql-28 Surveys, Courtney J. Austin, Dylan Chan Mar 2026

Exploring Adolescent Hearing Aid Usage And Appearance Of Psychiatric Symptoms In Adolescents Using Hearql-28 Surveys, Courtney J. Austin, Dylan Chan

MEDI 9331 Scholarly Activities Clinical Years

Approximately 2% of DHH people in need of mental health services actually receive these services. Among pediatric hearing loss populations, co-occurring cognitive and physical impairments are risk factors for poor mental health status. Due to language barriers and isolation, more children with hearing loss do not have access to mental health services. Cochlear implants have been shown to improve mental health status among the DHH population. Current literature focuses on the mental health status of children with cochlear implants, with little focus on hearing aid users. Using HEAR28 data and surveys, we can quantify the incidence of psychiatric symptoms among …


Devaluation Insensitivity Of Event Related Potentials Associated With Food Cues, Thomas D. Sambrook, Andy J. Wills, Ben Hardwick, Jeremy Goslin Mar 2026

Devaluation Insensitivity Of Event Related Potentials Associated With Food Cues, Thomas D. Sambrook, Andy J. Wills, Ben Hardwick, Jeremy Goslin

School of Psychology

Eating in the absence of hunger represents a failure of homeostatic mechanisms responsible for energy balance and is a cause of obesity. The pervasive presence of food cues in the modern environment may play a role in this phenomenon. The present study used the technique of satiety-specific selective devaluation to investigate eating in the absence of hunger in the context of a reinforcement learning task. While participants’ performance on the task suggested that food on which they had sated no longer held value for them, event related potentials following images of the food were unaffected by the devaluation. Food cues …

Does Genetic Testing Influence Outcomes: Early Experience In Melanoma Case Series, Ryan Reyes, George Skenteris, Stella Coker Watson Self Ph.D., Ms, Christine Marie-Gilligan Schammel, Steven D. Trocha

Faculty Publications

Background:

The treatment and prognosis of melanoma have historically been based on histologic stage and Breslow depth; however, due to the increase in surveillance, melanomas are being identified at an earlier stage and lower Breslow depth. Advances in genetic testing, such as Decision Dx®, mean that melanoma diagnostic decisions and prognosis can now be directed by genetics. The purpose of this project was to assess the influence of a Decision Dx® high-grade (Class 2A/B) classification on the treatment of melanoma patients at a regional medical center, particularly those not deemed high risk by conventional classification methods, including Breslow depth and …

Law's Penal-Professional World Order, Pilar Margarita Hernández Escontrías Mar 2026

Law's Penal-Professional World Order, Pilar Margarita Hernández Escontrías

Fordham Law Review

The attorney discipline regime has been propagandized as a necessary mechanism to police poor attorney conduct to protect the public. According to this myth, professional associations investigate attorney misconduct and impose sanctions, thus protecting the “noble profession” from attorneys who would tarnish its reputation. Violations of ethics rules lead to investigation, prosecution, and punishment by the state bar. In structure and language, state bars and judicial officers replicate the state in their use of disciplinary frameworks and regimes.

The self-regulating bar is a form of punitive governance used by the state to control entry into and expulsion from the profession. …

Faculty, Staff and Student Publications

Objective: We assessed the association between timing of moderate-to-vigorous physical activity (MVPA) with incident type 2 diabetes (T2D) and glycemic measures.

Research design and methods: Regression models were used to assess associations between accelerometer-derived MVPA timing and incident T2D in UK Biobank (UKB) (n = 84,528, prospective), prevalent diabetes, and glycemic measures in the National Health and Nutrition Examination Survey (NHANES) (n = 6,998, cross-sectional).

Results: In UKB, with early morning (0500-0959) MVPA as reference and before adjustment for total MVPA, "variable-timing" MVPA was associated with the lowest incident T2D risk; while after adjustment, afternoon-evening MVPA (1500-2400) showed the lowest …


A Scalable Iteration Of The Horizon Simulation Framework Using Multithreading Techniques, Jason E. Beals Mar 2026

A Scalable Iteration Of The Horizon Simulation Framework Using Multithreading Techniques, Jason E. Beals

Master's Theses

The Horizon Simulation Framework (HSF) occupies a unique space in the modern aerospace modeling landscape, enabling flexible, modular modeling of mission-level agent behavior through an object-oriented, hierarchical design. HSF's hallmark breadth-first search scheduling algorithm explores a "multiverse" of possible mission execution pathways, enabling exhaustive evaluation of schedule combinations against user-defined heuristics.

As aerospace systems become increasingly complex, HSF faces critical challenges in establishing verifiable, deterministic behavior. The framework's core scheduling algorithm had not undergone systematic validation, leaving questions about temporal consistency, state management correctness, and reproducibility across different program executions. Furthermore, the exponential growth of schedule combinations creates computational bottlenecks …

"Role Of Preoperative Echocardiography In Resource-Limited Settings And Delayed Patient Care", Zamanali Khakhar, Shamshudin Mohammedali, Sayed Karar Mar 2026

"Role Of Preoperative Echocardiography In Resource-Limited Settings And Delayed Patient Care", Zamanali Khakhar, Shamshudin Mohammedali, Sayed Karar

General Surgery, East Africa

Preoperative echocardiography has long been used as an effective diagnostic tool in the preoperative assessment of surgical candidates. In elderly patients, hip fractures represent a critical medical emergency with a high risk of complications that can occur if not addressed promptly. Unnecessary preoperative investigations may lead to delays and potentially compromise the quality of patient care. The motivation to evaluate the utility of preoperative echocardiography in select clinical scenarios, particularly in low- and middle-income countries (LMICs) where resources are limited, arose from the case of a 72-year-old female who presented to a tertiary hospital in Nairobi, Kenya, with a right-sided …

General Surgery, East Africa

Background Menstrual hygiene products (MHPs) may offer a high-reach, frequent, long-lasting yet underutilized channel for health education, particularly in low-resource settings. This study aimed to explore women’s breast health awareness (BHA) and their attitudes towards and preferences for BHA messages on MHPs.

Methods Women aged 18–49 years in Ghana and Tanzania (n = 438; 216 Ghana, 222 Tanzania), stratified by age and urban/rural setting, completed a questionnaire assessing socio-demographics, BHA, and preferences for BHA messages with MHP. BHA was assessed with an adapted 31-item Breast Cancer Awareness Measure Tool covering 4 domains: breast cancer signs and symptoms, confidence, skills, and …


Morphea With Seronegative Inflammatory Arthritis And Normal Acute Phase Reactants: A Case Report, Balakrishnan Navaneethakrishnan, Mahabaleshwar Mamadapur Mar 2026

Morphea With Seronegative Inflammatory Arthritis And Normal Acute Phase Reactants: A Case Report, Balakrishnan Navaneethakrishnan, Mahabaleshwar Mamadapur

Digital Journal of Clinical Medicine

Localised scleroderma, also known as morphea, is an immune-mediated fibrosing disorder that primarily affects the skin and subcutaneous tissues. While traditionally considered purely a cutaneous disease, extracutaneous manifestations (especially inflammatory arthritis) are increasingly being appreciated. The combined presence of morphea and inflammatory arthritis is rare and can be difficult to diagnose, particularly when inflammatory markers and serological testing are non-contributory.

Case Summary : We describe a 41-year-old woman with long-standing biopsy-proven morphea who over 2 years developed chronic, asymmetric inflammatory arthritis of the left wrist and hand small joints. On examination, she had active synovitis with restricted movements of her …

Magnetically Driven Engineering Of Magnetic Hydroxyapatite/Ca Ro Membranes: Enhancing Surface Physicochemical Properties For High-Performance Water Desalination, Fariba Oulad, Ali Akbar Zinatizadeh, Sirus Zinadini, Amir Razmjou, Sara Eavani

Research outputs 2022 to 2026

This research focuses on the development of innovative hydrophilic reverse osmosis (RO) hydroxyapatite/cellulose acetate (HAP/CA) and magnetic-hydroxyapatite (M-HAP)/CA membranes, utilizing a phase-inversion technique with varying nanoparticles (NPs) concentration. The positioning of magneto-responsive M-HAP NPs within the advanced M-HAP/CA membranes was adeptly controlled using magnetic guidance during immersion- precipitation process in a coagulation bath. This precise control enabled a densely organized arrangement of M-HAP NPs, shifting from the membrane's core to its upper separation layer. Consequently, the barrier properties, mechanical integrity, and surface characteristics of the advanced M-HAP/CA membranes saw significant enhancement due to the uniform distribution of hydrophilic porous NPs …

Explainable Artificial Intelligence Models For Detecting Suspicious Bank Transactions, Narasimha Kumar Narasapuram, Syed Afaq Ali Shah, Mohd Fairuz Shiratuddin, Ferdous Sohel

Research outputs 2022 to 2026

Detecting financial crime is a complex challenge due to evolving criminal strategies and fragmented detection systems, particularly in the areas of money laundering and fraud. While it is easy to implement, traditional rule-based approaches lack adaptability to new threats, and machine learning models, though more effective, often function as opaque "black boxes," limiting their practical use in regulated domains like banking, where interpretability and accountability are essential. This research presents a novel framework that combines intrinsic and post-hoc XAI techniques to detect suspicious bank transactions. Intrinsic methods provide model-inherent transparency, while post-hoc methods offer behavior-level explanations, enabling robust cross-verification of …

Pleural Metastases From Acral Lentiginous Melanoma Diagnosed By Medical Thoracoscopy, Ad Rian Chong, Khai Lip Ng, Nai-Chien Huan, Nur Husna Mohd Aminudin, Fazilah Hassan, Kasuma Mohamed Nordin

Research outputs 2022 to 2026

Acral lentiginous melanoma (ALM) with pleural metastases is rare and under-recognised. We report an 86-year-old woman with progressive dyspnoea and pleuritic chest pain. 18 months ago, she was diagnosed with stage IIC ALM of the right heel, and was treated with wide local excision, but she declined adjuvant therapy. Imaging demonstrated a large left pleural effusion with diffuse pleural thickening, pulmonary mass, and hepatic metastases. Brownish pleural fluid, along with thoracoscopic identification of multiple pigmented nodules, led to a histologically confirmed diagnosis. Talc pleurodesis was performed for symptom control, and best supportive care was pursued. This case highlights the diagnostic …


Improvements In The Thermal Stability And Mechanical Robustness Of Holograms Recorded In Acrylamide/Polyvinyl Alcohol-Based Photopolymers Through The Use Of D-Sorbitol As A Plasticizer, Michael Murray, Aaron Byrne, Izabela Naydenova, Suzanne Martin Mar 2026

Improvements In The Thermal Stability And Mechanical Robustness Of Holograms Recorded In Acrylamide/Polyvinyl Alcohol-Based Photopolymers Through The Use Of D-Sorbitol As A Plasticizer, Michael Murray, Aaron Byrne, Izabela Naydenova, Suzanne Martin

Research Outputs: 2025-Present

In this work, a photopolymer formulation is presented that demonstrates significant improvements in layer hardness and temperature stability, while retaining the excellent holographic recording characteristics and ease of preparation associated with acrylamide (AA)/polyvinyl alcohol (PVA)-based photopolymers. This is achieved through the use of N-phenyl glycine as an electron donor and, for the first time, D-Sorbitol, a naturally occurring sugar-alcohol, as a plasticizer. The plasticizing effect of D-Sorbitol is demonstrated through the minimal loss of diffraction efficiency (η) observed upon UV bleaching (fixing) of 500 lines/mm gratings, which is evidence for effective mass transport during holographic recording. This solves a key …
