Electron Beam Irradiation Effects On Bulk Metals And High Entropy Alloys (Crmnv And Crmntiv) And The Synthesis And Characterization Of Irradiation-Induced Damage In Polycrystalline Metal And High Entropy Alloy Thin Films, Najmin Ara Sultana

Mechanical & Aerospace Engineering Theses & Dissertations

Accelerator beam exit windows are designed to withstand intense radiation and mechanical stress while preserving beam transmission and structural integrity. This dissertation explores the structural and mechanical responses of pure metals and high-entropy alloys (HEAs), in both bulk and thin-film forms, under high-dose electron beam (e-beam) irradiation to identify optimal materials for next-generation accelerator exit windows. Monte Carlo simulations using FLUKA, conducted at Jefferson Lab, revealed that amongst Ni, Ti, Cr, and V, Ni exhibits the highest power dissipation, while Ti depicts the lowest power dissipation, with Cr and V demonstrating intermediate characteristics. Bulk polycrystalline (PC) and single-crystalline (SC) samples …

Unraveling Nonperturbative Qcd With Transverse Momentum Hadronic Structures, Tommaso Rainaldi

Physics Theses & Dissertations

The main purpose of this thesis is to investigate the theoretical foundations of the factorization theorems that involve transverse quark and gluon momentum distributions, and to better understand the interface between foundational questions and phenomenological applications. Many of these applications involve using transverse parton momentum dependent (TMD) correlation functions as tools for probing the complex nonperturbative structures of the hadrons.

We first introduce the concepts of collinear and TMD factorization in a toy-model theory and, by leveraging the comparative simplicity of such a model, we test the range of validity and limitations of the factorization approach. At the same time, …

Unique Architecture: In Praise Of Paradox Persistence, Odaly Plancarte

Theses

This thesis explores how bold and unconventional architectural designs are first rejected and later embraced by the public. Through a comparative study of the Sydney Opera House, the Louvre Pyramid, and the Walt Disney Concert Hall, it examines how public opinion shifts over time. Using media reports, interviews, and public comments, the study tracks emotional responses (positive, neutral, or negative) assigned a score to measure change over the years. The research applies Everett Rogers’ Diffusion of Innovation Theory to explain this shift in five stages: knowledge, persuasion, decision, implementation, and confirmation. Each building faced early backlash, but eventually became a …

Characterizing Tcap Set-Ups For Effective Separation On Hydrogen Isotope Species, James R. Hanby

Theses

Hydrogen isotope separation was investigated using a series of thermal cycling absorption process (TCAP) experiments. Pulse tests were conducted using deuterium injected into a protium flow over a range of superficial velocities, temperatures, particle sizes, and column diameters to quantify the efficiency of this process for a palladium on kieselguhr catalyst. The resulting response curves, obtained from residual gas analysis, were used to calculate the height equivalent to a theoretical plate (HETP) in each case. These values were then fit with van Deemter curves to illustrate the change in HETP over gas velocity. A strong positive correlation with temperature was …

Quantifying Marine Carbon Dioxide Removal Via Alkalinity Enhancement Across Circulation Regimes Using Ecco-Darwin And 1d Models, Kay Suselj, Dustin Carroll, Daniel Whitt, Bridget Samuels, Dimitris Menemenlis, Hong Zhang, Nate Beatty, Anna Savage

Faculty Research, Scholarly, and Creative Activity

Ocean Alkalinity Enhancement (OAE) is emerging as a viable method for removing anthropogenic (Formula presented.) emissions from the atmosphere to mitigate climate change. To achieve substantial carbon reductions, OAE would need to be deployed at scale across the global ocean. Hence, there is a need to quantify how the efficiency of OAE varies globally across a range of space-time scales in preparation for field deployments. Here we develop a marine carbon dioxide removal (mCDR) efficiency evaluation framework based on the data-assimilative ECCO-Darwin ocean biogeochemistry model, which separates and quantifies two key factors over seasonal to multi-annual timescales: (a) mCDR potential, …

The Unique Function Of The Crime Against Humanity Of Other Inhumane Acts In The Progressive Development And Codification Of International Criminal Law, David Donat Cattin

Cardozo International & Comparative Law Review

The article explores the evolution and role of "other inhumane acts" as a residual category within the definition of crimes against humanity, tracing its development from the Nuremberg trials through the Rome Statute of the International Criminal Court (ICC). It highlights the potential of this category to adapt to new forms of atrocities and discusses the challenges and opportunities in aligning future treaty developments with existing legal frameworks.

No More Mixed Message, Missing Money: Revisiting The Birth Of Icl’S Victim Restoration-Reparations Regime To Conceptualize Its Modern Reform, Gregory S. Gordon

Cardozo International & Comparative Law Review

The article argues that the International Criminal Court's (ICC) system for victim reparations is fundamentally flawed due to mission dissonance between its punitive and restorative goals, insufficient funding, and procedural limitations. It proposes the creation of an independent Atrocity Victim Reparations Tribunal (AVRT) under the UN to address these issues, ensuring more effective and victim-centered reparations.

Modeling Multiple Tasks In Recommendation Systems, Dinh Hieu Do

Dissertations and Theses Collection (Open Access)

Traditional research in recommendation systems has largely centered on the static offline supervised learning setting. In this paradigm, all available user-item interaction data is collected and partitioned into fixed training, validation, and test sets. Models are developed and evaluated in this controlled environment, where the underlying data distribution is assumed to remain unchanged. This approach offers clear advantages: it simplifies experimentation, enables reproducible benchmarking, and allows for straightforward comparisons between algorithms.

However, this static offline setting does not reflect the realities faced by modern recommendation systems. In real-world applications, data is dynamic and ever-evolving, where new users and items are …

From Sparse Feedback To Sequential Decision-Making: Learning Safety Constraints With Weak Supervision, Siow Meng Low

Dissertations and Theses Collection (Open Access)

Real-world decision-making often involves safety constraints that are implicit, non-Markovian, or difficult to specify directly. Standard reinforcement learning (RL) approaches typically assume access to fully specified cost functions and constraint budgets—assumptions that limit their applicability in domains where such structure must instead be inferred from data. This dissertation develops a sequence of methods for learning safety-relevant structure from weak supervision, such as sparse binary feedback on trajectory segments, and using these signals to guide planning and policy optimization.

The first part of the dissertation introduces a sample-efficient method for planning in continuous Markov Decision Processes (MDPs) using deep reactive policies. …

From Disruption To Integration: Cryptocurrency Prices, Financial Fluctuations, And Macroeconomy, Zhengyang Chen

Faculty Publications

This paper examines cryptocurrency shock transmission to financial markets and the macroeconomy using a Bayesian structural VAR with Pandemic Priors from 2015 to 2024. By affecting overall risk appetite, cryptocurrency price shocks generate positive financial market spillovers, accounting for 18% of equity and 27% of commodity price fluctuations. Real economic effects are significant in driving investment but remain limited, contributing only 4% to unemployment and 6% to industrial production variance. However, cryptocurrency shocks explain 18% of price-level forecast error variance at long horizons. Narrative analysis reveals sentiment and technology as primary shock drivers. These findings demonstrate cryptocurrency's deep financial system …

Moving Drives You Crazy, Michelle C. Dziurgot

The Journal of the Michigan Dental Association

The Editor-in-Chief shares her frustrating experience moving a dental office. Key challenges included dental insurances dropping the practice from networks during recredentialing, causing denied claims for 30-60 days despite no changes to tax ID or NPI. State regulations also required new payments for radiation tubes, rather than crediting previous payments, despite a reduction in equipment. Furthermore, dental supply companies and movers did not take responsibility for broken equipment during the move. Despite these "insane and archaic" hurdles, most patients transitioned, and the article concludes with a comprehensive resource list for practice address changes
