Asymptomatic Tb Duration And Transmission Models, Zhichao Zhou

Public Health Theses

Tuberculosis (TB) transmission is sustained in part by asymptomatic disease states that limit the effectiveness of passive case finding interventions that rely on symptom-based diagnosis. Here we develop a transmission model that represents the duration of asymptomatic disease with a gamma-distributed waiting time. By chaining multiple asymptomatic sub-states, we find that the gamma-distributed model provides a better fit to the observed distribution of the duration of asymptomatic disease than a simple one-state model which imposes an assumption of an exponentially-distributed duration of asymptomatic disease. Comparing the fitted gamma-distributed model and the simple model, we quantify how assumptions about the distribution …

Climate Change Impacts On Hydrology In The Upper James Watershed, Imiya Mudiyanselage Chathuranika, Dalya Ismael

Engineering Technology Faculty Publications

Hydrological modeling of the Upper James Watershed (UJW), Virginia, is critical for predicting water availability, flood management, agriculture, ecosystem protection, and hydropower production under increasing climate change. The Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) is applied to evaluate climate change impacts on key hydrological components within the watershed. Future climate conditions were assessed for the near (NF: 2026-2050), mid (MF: 2051-2075), and far (FF: 2076-2100) periods using three Global Climate Models (GCMs) under Shared Socioeconomic Pathways SSP 2-4.5 and SSP 5-8.5. Climate data were bias-corrected using the Linear Scaling Method (LSM) and used to drive the HEC-HMS model. Results project …

Assessing Climate Change Impacts On Wildfire Risk In Central Appalachian Forests Of The Eastern United States, Imiya Mudiyanselage Chathuranika, Dalya Ismael

Engineering Technology Faculty Publications

Wildfire risk is increasing in the eastern U.S., yet spatial and climate-driven assessments remain limited. This study evaluates climate change impacts on wildfire risk in the Upper James Watershed (UJW) using baseline (2000–2019), near-future (2021–2040), and far-future (2061–2080) projections from a 12-model CMIP6 global climate model (GCM) ensemble under SSP2–4.5 and SSP5–8.5. A wildfire risk model was developed in ArcGIS Pro using nine key factors and validated with MODIS hotspot data, showing good agreement between modeled risk patterns and observed fire occurrences (NOF = 0.21, RMSE = 4.20, MAE = 3.37). Baseline risk was primarily driven by land cover, fire-lookout …

Improving Medical Diagnostics With Vision-Language Models: Convex Hull-Based Uncertainty Analysis, Ferhat Ozgur Catak, Murat Kuzlu, Taylor Patrick, Michel Audette

Engineering Technology Faculty Publications

In recent years, vision-language models (VLMs) have been applied to various fields, including healthcare, education, finance, and manufacturing, with remarkable performance. However, concerns remain regarding VLMs’ consistency and uncertainty, particularly in critical applications such as healthcare, which demand a high level of trust and reliability. This paper proposes a novel approach to evaluate uncertainty in VLMs’ responses using a convex hull approach on a healthcare application for visual question answering (VQA). For any VLM, temperature refers to a sampling parameter used in probabilistic generation, which controls the randomness of the model’s output. The LLM-CXR model is selected as the medical …

Through A Glass Darkly: Targeting Cyber And Space Infrastructure In The Law Of War, Michael D. Minerva

Chapman Law Review

As modern militaries become more capable in the cyber and space domains, much of the legal debate has focused on how to legally conduct cyber and space operations. While important, that discussion has largely overlooked the legal implications for the rapidly growing cyber and space infrastructure that exists in the physical domain—commercial satellites like Starlink filling the night skies and data centers like those popping up all over northern Virginia. Most of this infrastructure is commercially developed and privately owned—presumptively civilian in nature—and yet used by militaries all over the world.

The same way bridges form critical ground lines of …

Tilting The Playing Field: Executive Attacks On Big Law Firms As A Mechanism Of American Competitive Authoritarianism, Sajah Ali

CMC Senior Theses

This thesis examines how President Donald Trump’s executive campaign against elite law firms, collectively known as “Big Law,” serves as a concrete case study of competitive authoritarianism in action. Drawing on Steven Levitsky and Lucan Way’s framework in their work The Path to American Authoritarianism, this thesis applies their four pillars of competitive authoritarianism to the administration’s executive orders targeting major law firms and maps those pillars onto three distinct firm responses: fighting back, capitulation, and quiet retreat. Situating this case study within the broader political context of Trump’s second term, this thesis finds that while the United States has …

Short-Window Market Reactions To Real Estate M&A: A Comparative Event Study Of Reits And Real Estate Services Firms, Aryan Kaila

CMC Senior Theses

Existing research on real estate mergers has largely focused on REIT acquirers in isolation, typically finding near-zero bidder reactions in short event windows. There is little work that directly compares REITs with publicly listed real estate services (RES) firms that operate in the same market cycles and conditions but follow different business models. Using a transaction-level dataset of 137 U.S. mergers from 1994 to 2024, this study applies event-study methodology and cross-sectional regression analysis to investigate whether equity markets respond differently to acquisitions undertaken by REITs and real estate services firms. The estimates show that REIT acquirers experience notably more …

The Complex Decision-Making Processes Of Rural Emerging Adults: Counseling Beyond Dualism, Donna M. San Antonio Dr.

Faculty Scholarship

Rural adolescents approach the transition out of high school with individual concerns about making an emotionally or financially expensive “mistake,” family concerns about young people leaving home, and national and local concerns about declining rural economies and out-migration. The literature concerning this topic considers factors that influence youth aspirations in rural areas, such as economic barriers, the way higher education is valued, and perceptions of rural places as lacking in opportunity. However, there has been little study of the myriad interpersonal, emotional, and self-identity inputs that are part of the decision-making processes of rural emerging adults, and little is known …

The essentiality of protein in the human diet is unequivocal. Yet researchers, clinicians, and lay people often believe numerous propositions about dietary protein despite insufficient supporting or refuting data in some instances. To address this disconnect, and to "pressure-test" current beliefs about dietary protein, the Indiana University School of Public Health-Bloomington convened a workshop in February 2025 titled "Human Dietary Protein Needs and Benefits: A Critical Assessment of Postulated Propositions." More than 20 international experts discussed (1) methodologic issues affecting data acquisition and interpretation; (2) "optimal" dietary protein intakes and effects on muscle protein synthesis rates, muscle protein accretion, …

Regulating Space-Based Solar Power: Challenges Under Both Space Law And Energy Law, Anne-Sophie Martin, Steven Freeland

Journal of Air Law and Commerce

Space-based solar power (SBSP) is emerging as a potential catalyst for global decarbonisation, driven by advances in wireless power transmission, in-orbit assembly, and photovoltaic technologies. Programmes such as the European Space Agency’s SOLARIS initiative, China’s planned megawatt-scale demonstrator, and private projects including Constant Aperture Solid State Integrated Orbital Phased Array and Caltech’s Space Solar Power Project illustrate the shift from theoretical models to operationalisation. SBSP offers continuous, weather-independent renewable energy capable of complementing terrestrial solar, wind, and hydro generation, enhancing grid stability, energy security, and progress toward the UN Sustainable Development Goals. It also supports future space activities by providing …

Systemic Legal Scholarship For Systemic Ai, Kevin Frazier

Chapman Law Review

Artificial intelligence (AI) is triggering societal transformation at an unprecedented pace, yet our legal system struggles to keep up, often relying on incremental tweaks to outdated rules. This Article argues that such conventional legal thinking is not just inadequate but also a source of inconsequential scholarship. By failing to anticipate AI’s trajectory and address foundational issues, incrementalism allows “legal tech debt” to mount, increasing risks of policy failure, societal disruption, and erosion of the rule of law. We must leapfrog this dangerous inertia. This Article proposes and defines a necessary alternative: systemic legal scholarship. This forward-looking paradigm requires legal experts …

Titanium Hypersensitivity As Possible Cause Of Dental Implant Failures, William J. Maloney D.D.S., Pg Certmeded, Facd, George Raymond D.D.S., Facd, Maura Maloney D.D.S.

The New York State Dental Journal

For many decades, titanium implants have achieved a remarkably high success rate. However, there are cases in which osseointegration does not occur as predicted or desired. In these cases, an analysis of the factors that led to the implant failure must be conducted. There are multiple, widely accepted potential causes of such implant failures. Today, one must also consider titanium hypersensitivity as a potential reason for failure. Symptoms of a titanium allergic reaction may include mucosal erythema, swelling of lips, purpuric patches on hard and soft palate, ulcers in the oral cavity, hyperplastic gingivitis, cheilitis, eczematous eruptions on face and …

Generational Differences In Dentistry And Dental Practice, Ellen Lee Dds, Brian Chin M.B.A., Hazel Hong, Daranthea Atmadja, Jong Soo Lim, Jamie Chen, Chloe Lin, Chloe Naeun Kim

The New York State Dental Journal

Society is composed of workers from different generations. These include the Silent Generation, or Traditionalists, Baby Boomer Generation, Generation X, Millennials and Generation Z. Generation Alpha will join the workforce in the next decade. The way each generation has approached dentistry depends on available materials and technology, as well as contemporary societal values. In addition, major historical events and the state of the economy may have been and are contributing factors in how each generation practiced or practices dentistry.

Hiv Screenings In Dental Settings Feasibility, Challenges And Opportunities, Leander Nguyen, Melissa Yap, Ezzard Rolle Dds, Alison Newgard Dds

The New York State Dental Journal

Integrating human immunodeficiency virus (HIV) screening into dental settings presents a valuable opportunity to enhance early detection and reduce transmission rates. Dentists regularly interact with at-risk populations and can use rapid oral fluid tests, which are noninvasive and reliable. Studies show that both dental professionals and patients are generally receptive to this practice, though barriers remain, including cost, provider training and concerns about scope of practice. Implementing structured education, clear protocols and interprofessional collaboration can support widespread adoption. Overall, dental HIV screening holds promise as a feasible and impactful public health intervention.

All Rsif Scholars' Publications

This study presents a sustainable route to synthesize graphene oxide (GO) from rice husk biochar (RHB) without hazardous HF/NaOH pretreatment, using a modified Hummers’ method. We showed that natural silicate minerals in RHB significantly alter the structure and properties of rice husk-derived GO (RHGO), reducing its electrochemical sensing performance compared to commercial graphite-derived GO (CGGO). Importantly, we demonstrated that a simple, eco-friendly process, decantation followed by electrodeposition, can reduce the adverse effects of silica in RHGO, boosting its sensing performance without needing traditional desilication methods. XPS analysis revealed that RHGO exhibited a higher silicon content of 28 % and oxygen …

The agricultural landscape in Rivers State, Nigeria, is increasingly threatened by the dual challenges of escalating flooding events and return migration. Historically, flooding in the region has shifted from isolated incidents to a persistent and widespread hazard, significantly disrupting agricultural livelihoods and rural stability. This study assessed the effects of flooding-induced migration on the food security status of farming households in Nigeria. Data were collected on the episodes that occurred between 2011–2022 to estimate the coping strategies of the farmers. The farm revenue specifically from 2022 production activities was also computed. This was used in estimating the effect of flooding-induced …

A Lightweight Quantum-Secure Authentication And Key Agreement Protocol For Vehicular Ad-Hoc Networks, Lasseni Coulibaly, Damien Hanyurwimfura, Evariste Twahirwa, Abubakar Diwani

All Rsif Scholars' Publications

Intelligent transportation systems, a critical pillar for smart cities, enable real-time vehicular communications to prevent human errors and improve traffic safety and efficiency. However, the open and highly dynamic nature of vehicular networks exposes them to various security threats, including message tampering, impersonation, and privacy violations. Several authentication and key agreement (AKA) protocols have been proposed to mitigate these risks, but often fail to maintain future-proof security against emerging quantum threats or introduce significant latency that affects real-time applications by relying on computationally expensive public-key cryptography, blockchain or centralized architectures. This paper proposes a new AKA protocol that combines hash-based …

Modeling Of Intraday Fluctuations In Future Climate Parameters And Their Impact On Perovskite Solar Modules, From A Sustainable Development Perspective, Wakiang Emile Latchiba, Sebastian Waita, Robert Kruege, Julius M. Mwabora

All Rsif Scholars' Publications

Modeling of intraday fluctuation in future climate parameters. This study uses ARIMA and LSTM models to evaluate and examine the prediction accuracy of four main meteorological parameters (solar irradiance, temperature, relative humidity, and wind speed) that have an impact on perovskite solar modules using Chad as an example. The findings show that the use of averaged climatic data considerably obscures the effects of intraday fluctuation, which significantly increases power output volatility and speeds up degradation. Increasing short-term temperature extremes may further jeopardize system reliability, according to projections under future climate scenarios. The results highlight the necessity of climate-resilient photovoltaic modeling …
