Utility Of Model-Based And Probabilistic Approaches For Rocket Engine Affordability : Exemplified On The Rs-25 Engine, Shreyas Lakshmipuram Raghu

Dissertations

Rocket engine development has historically relied on test–fail–fix (TFF) methodologies to uncover structural and fatigue deficiencies under representative operating conditions. While effective, TFF is inherently costly and schedule-intensive, often revealing life-limiting behavior late in the development lifecycle. The increasing use of additive manufacturing (AM) amplifies this challenge by introducing material property scatter and process-induced variability. Without explicit early treatment of uncertainty, these effects can increase reliance on physical testing and drive additional TFF cycles. This work presents a reliability-driven life-consistent design-bounding framework intended as an early lifecycle decision-support tool to assess and mitigate TFF risk. Although material variability is inherently …

Hexavalent Chromium Promotes Malignant Transformation Via Enhanced Translation Of Suv39h1, Yiwei Gu, Yanan Cao, Qing Ye, Yujing Zhang, Zhishan Wang, Chengfeng Yang, Side Liu, Qing-Bai She

Markey Cancer Center Faculty Publications

Hexavalent chromium [Cr(VI)] is a widespread environmental carcinogen linked to lung cancer and other malignancies. Although genetic and epigenetic mechanisms of Cr(VI)-induced carcinogenesis have been extensively investigated, the role of translational control has remained largely unexplored. Here, we show that chronic low-dose Cr(VI) exposure in BEAS-2BR human bronchial epithelial cells activates eIF4E-driven cap-dependent translation through mTORC1-mediated phosphorylation and inactivation of the translational repressor 4E-BP1. Pharmacological inhibition of this pathway markedly suppresses Cr(VI)-induced cell transformation, cancer stem cell (CSC)-like properties, and DNA damage. Comparable inhibitory effects are observed following raptor knockdown, which disrupts mTORC1, or expression of a constitutively active non-phosphorylatable …

Objective: This study examined the recent experiences of families of critical care (intensive care unit; ICU) patients related to anxiety and depression (AD), satisfaction with clinician-family communication, and counseling from mental health and social services. This study explored correlations between these factors and family interest in mobile health (mHealth) designed to improve information flow and communication from patient bedside …

The Global Privacy Frontier: Bridging User Expectations And Ai In Mental Health Technology, Salauddin Ahmed, Mohammad Asaduzzaman

Student Publications

This study examines privacy concerns in AI-driven mental health apps through the lens of Communication Privacy Management (CPM) theory, utilizing qualitative research of consumer opinions on Google Play Store. It explores how global consumers articulate privacy concerns, experience boundary turbulence in online conversations, and exhibit culturally oriented privacy expectations in this high-stakes emerging tech arena. Results indicate that users are most likely to voice concerns about control and transparency of data, with ambiguous privacy policies raising suspicion. Boundary turbulence narratives, e.g., improper use of data, are most directly related to loss of trust and app abandonment, highlighting critical challenges for …

How Wasteful Is Signaling?, Alex Frankel

Cowles Foundation Discussion Papers

Signaling is wasteful. But how wasteful? We study the fraction of surplus dissipated in a separating equilibrium. For isoelastic environments, this waste ratio has a simple formula: β/(β + σ), where β is the benefit elasticity (reward to higher perception) and σ is the elasticity of higher types’ relative cost advantage. The ratio is constant across types and independent of other parameters, including convexity of cost in the signal. A constant waste ratio characterizes the isoelastic class. In winner-take-all signaling tournaments with N candidates, exactly (N − 1)/N of the surplus dissipates—the same as in Tullock contests.

Practicing Professionalism Framework: A Coherent Course Structure Aligned With Effective Practices For Physics Programs (Ep3) Guidelines, Martha-Elizabeth Baylor, Suzanne White Brahmia

Physics and Astronomy Faculty Work

Many physics educators seek to improve their courses but feel constrained by traditional post-secondary structures and norms. Instructors often perceive a false tension between fostering inclusive learning environments and maintaining the rigor central to the discipline. The Effective Practices for Physics Programs (EP3) Guide synthesizes decades of research-based recommendations for improving physics education. However, it offers limited guidance on how to integrate these diverse recommendations into a coherent, course-level approach—a responsibility that falls to individual instructors, whose graduate training prepared them primarily as researchers rather than as educators. This paper begins by motivating and introducing the Practicing Professionalism Framework (PPF), …

Challenges And Applications Of Fine-Grained Temporal Action Understanding: Modeling Temporal Granularity And Data Efficiency, Halil I. Helvaci

Theses and Dissertations--Electrical and Computer Engineering

Fine-grained Temporal Action Segmentation (TAS) has become a cornerstone of video understanding, offering dense frame-level predictions essential for clinical assessment, surgical skill evaluation, and human-computer interaction. While TAS methods have delivered strong results on coarse-grained benchmarks, two fundamental challenges persist: (1) global attention mechanisms dilute boundary information critical for subsecond precision, a phenomenon we term the temporal granularity bottleneck, and (2) dense frame-level annotation remains prohibitively expensive, with most datasets requiring exhaustive labeling of lengthy untrimmed videos. These challenges are particularly pronounced in medical domains, where sub-second primitives define clinical outcomes while expert annotation remains scarce. In this dissertation, we …

Age, Law, And Political Economy, Alexander Boni-Saenz

Articles

This Article examines the intersection of age, class, and the law. Its central claim is that age is an essential dimension for the analysis of law and political economy. There are two primary reasons why. First, age is embedded in a large body of legal rules that structure the labor market and address vulnerabilities associated with particular life stages. Child labor laws set minimum ages for entry into the workforce, while social welfare laws use age eligibility criteria to shape the material conditions for older adults. Second, age and its sibling concept, generation, indirectly shape economic and political relations by …

Richmond, Fredericksburg & Potomac Passenger Rail Performance And Ridership Study, Matthew S. Sturgis

Master of Urban and Regional Planning Capstone Projects

This study evaluates how targeted infrastructure and operational improvements could improve speed, reliability, and, by extension, ridership on the Richmond, Fredericksburg, and Potomac Corridor between Richmond Main Street Station and Washington Union Station. Although the corridor carries all 198 weekly Amtrak trains operating in Virginia over some portion, passenger rail remains materially less competitive than automobile travel on I-95 when compared under ideal travel conditions or by mode share. In 2024, the corridor carried 1,046,255 riders and held an estimated rail mode share of 2.4 percent relative to 42,598,057 vehicle trips on comparable I-95 segments. At the same time, average …

Richmond, Virginia has added several new parks in recent years. However, there are still gaps between existing conditions and the City’s goal of having all residents live within a 10-minute walk of a quality park. The plan presents a land acquisition and maintenance strategy for future parkland expansion in the City of Richmond. Three questions guided the research: 1) which areas in Richmond are priority areas for creating new parks? 2) what processes should Richmond use to acquire land to expand …

No 'Dexit': Delaware's New Statutory Corporate Law Loosens The Restrictions On Controlling Shareholder Transactions In Response To Corporate Outlash Following Tornetta V. Musk, Reid A. Manabat

Emory Business Law Review

The recent Tornetta v. Musk decisions caused upheaval in the Delaware corporate community. Throughout 2024, shareholder executives have left or threatened to leave Delaware to incorporate elsewhere in a move termed “DExit.” The threat did not go unnoticed by Delawareans and lawmakers who contemplated a two-billion-dollar loss to the state’s tax revenue. Despite the courts’ willingness to require heightened scrutiny for conflicted-controller transactions, in recent years lawmakers have lowered the bar. I argue that Delaware’s new statutory corporate law does not adequately protect minority shareholders from conflicted controllers. First, the new statutory cleansing mechanisms ignore the unique dangers of conflicted-controller …

U.S. Administrative Law: A Casebook (6th Ed.), Jud Mathews

Faculty Scholarship

The number of administrative law texts is vast. The approach of this one, now in its fifth edition, is simple. It is: (1) to focus on the richest and most canonical cases; (2) to provide more extensive extracts of them than most casebooks; and (3) to keep the notes to a bare minimum. Updated through October 2025, the book contains a number of significant decisions from recent Supreme Court terms, as well as foundational classics that many contemporary casebooks cut, and much in between.

Blockchain As A Digital Coordination Infrastructure For Project Management: A Systematic Review And Integrative Framework, Cherie Bakker Noteboom, Sai Neelima Seru, Aravindh Sekar

Journal of International Technology and Information Management

Blockchain technology has gained increasing attention as a digital infrastructure capable of improving transparency, trust, and coordination in complex, multi-organizational project environments. However, existing research on blockchain-enabled project management remains fragmented and industry-focused, providing limited guidance for organizational adoption and integration. This study addresses this gap through a systematic literature review of 29 peer-reviewed studies, following PRISMA guidelines, to examine how blockchain capabilities are incorporated into project management practices across industries and maturity stages.

Grounded in Resource-Based View and Coordination Theory, the analysis employs a feature-to-process mapping approach to link six core blockchain capabilities—decentralization, transparency, immutability, smart contracts, traceability, and …

Habitar Lo Vivo, Sara Sánchez-Herrera Cubero

Grado en Diseño de Interiores

The project proposes a Centre for Research into Cognitive Development based on the principles of biophilia, understood as the natural connection between humans and nature. Based on an analysis of the existing building, a rational, modular steel structural system has been developed which contrasts with the organic and sensory dimension of the biophilic design, creating a dialogue between the artificial and the natural. The building is completely hollowed out whilst retaining its structure and façade—as the skeleton and skin of the rationalist movement—and this modular steel structure is incorporated; thanks to its own strength, it can easily create spaces. The …

Escenarios Coreográficos, Sara Juárez Díaz

Grado en Diseño de Interiores

Although Espacios Coreográficos is conceived as a contemporary intervention, it establishes a conceptual dialogue with the principles that informed Rafael Bergamín’s original design. Beyond its physical language, the Casa del Marqués de Villora embodies a rationalist approach in which architecture becomes a tool for organising everyday life through clarity, order and carefully articulated relationships between spaces. Spanish Rationalism was not exclusively concerned with constructional efficiency or aesthetic reduction. It also sought to redefine domestic experience by proposing new ways of inhabiting space, where movement, light and functional organisation shaped daily routines. In this sense, architecture operated as an instrument capable …

Potential Of Crispr/Cas9 Genome Engineering For Biofuel Production From Economically Relevant Algae, Sundram Kumar, Ankur J. Phillips, Bashir Adelodun, Francesco Di Maria, Suresh Sundaramurthy, Tarun Pal

Arusha Climate and Environmental Research Centre

The worldwide energy demand continues to rise, while reliance on fossil fuels remains unsustainable due to global warming, declining reserves and rising oil prices. This has intensified the search for renewable alternatives. Among these, microscopic algae have emerged as a promising feedstock for third-generation biofuels. Owing to their rapid biomass productivity, high lipid content and ability to generate diverse bioproducts, microalgae offer distinct advantages over terrestrial plants. Lipids derived from algae can be converted into biodiesel, while their biomass yields valuable co-products such as carbohydrates, proteins and polyunsatu- rated fatty acids (FAs). These attributes position algae as critical contributors to …

Improving Pid Control With Bayesian Optimization For Adversarially Robust Federated Learning, Adrian Pena, Sergei Chuprov, Raman Zatsarenko, Leon Reznik

Computer Science Faculty Publications

Federated Learning (FL) often suffers from unstable convergence and reduced robustness under non-IID data and malicious attacks. In this paper, we present FedPIDAvg_tuned, a control-theoretic aggregation framework for improving stability and adversarial robustness in FL. In particular, our approach combines a server-side Proportional–Integral–Derivative (PID) controller with Bayesian optimization to tune controller gains for different data and attack conditions. The PID controller regulates global model updates through feedback on loss dynamics, providing adaptive scaling that improves stability and convergence. The tuned gains are applied within a trust-weighted trimmed-mean mechanism to remove adversarial or outlier updates. Using the Flower framework, we evaluate …

Educational technologists have not settled on a fixed definition of the field and likely never will. However, attempting to define the field helps to understand the epistemological meanings that shape what the field sees, values, and considers worth pursuing. Through a critical historical review spanning over a century, alongside theoretical engagement with the concepts of entanglement and distributed agency, this paper identifies three key insufficiencies in current educational technology frameworks. These are the persistence of an instrumental-facilitative paradigm that treats technology as a resource deployed by human agents; the theoretical dissolution of the pedagogy-technology dichotomy that existing definitions have not …

Implementing Hepatitis C Screening And Treatment In Primary Care, Michele Castellano Wetmore

Yale School of Nursing Digital Theses

AbstractHepatitis C (HCV) is a curable hepatic disease. With direct-acting antivirals, it can be treated in 95% of cases. When left untreated, it can cause severe liver disease, including hepatocellular carcinoma and even death. The World Health Organization’s (WHO) goal is to eliminate HCV by 2030. This Quality Improvement (QI) project, conducted at a Federally Qualified Health Center (FQHC) from 8/4/2025 to 11/4/2025, will address the barriers to elimination and show that providing local services closes gaps. Screening and treating HCV within primary care has become a strategic approach to enhance access to treatment. This involves developing and utilizing a …
