Faculty, Staff and Students Publications

BACKGROUND: MECP2 Duplication Syndrome, also known as X-linked intellectual developmental disorder Lubs type (MRXSL; MIM: 300260), is a neurodevelopmental disorder caused by copy number gains spanning MECP2. Despite varying genomic rearrangement structures, including duplications and triplications, and a wide range of duplication sizes, no clear correlation exists between DNA rearrangement and clinical features. We had previously demonstrated that up to 38% of MRXSL families are characterized by complex genomic rearrangements (CGRs) of intermediate complexity (2 ≤ copy number variant breakpoints < 5), yet the impact of these genomic structures on regulation of gene expression and phenotypic manifestations have not been investigated.

METHODS: To study the role of the genomic rearrangement structures on an individual's clinical phenotypic variability, we employed a comprehensive …

Considering The Impact Of Ai On The Professional Status Of Teaching, Benjamin D. Parker

Educational Studies

The purpose of this perspective essay is not to dissect the merits or deficits of AI in practice in classrooms, nor is it intended to approach the topic from a technical standpoint. Rather, this manuscript begins from a place of acceptance, recognizing that AI in education is already here and the adaptive and evolutionary nature of the technology positions it to maintain a presence in schooling spaces for the foreseeable future. From there, assuming AI will become further integrated into the fabric of schooling experiences, it seems necessary to take a step back and look holistically at the potential impact …

Schedulability Analysis Of Multi-Phase Limited-Preemption Tasks, Benjamin Standaert

McKelvey School of Engineering Graduate Student Theses & Dissertations

This work addresses hard real-time systems, in which tasks must be scheduled so that they are guaranteed to meet deadlines. In particular, when tasks execute across multiple domains with high preemption costs, the combined cost of these preemptions can cause the system to become unschedulable. The number of preemptions must therefore be bounded to limit the overall task execution time, while ensuring that task blocking times are small enough to allow the system to be schedulable. Prior work introduces the Multi-Phase Secure model, which describes a more exact version of this scenario, and an algorithm to determine schedulability of sporadic …

Brazilian Instrumental Music, U.S. Jazz, And Transnationalism: A Study Of National Identity In The Twentieth Century And Present, Felipe Guz Tinoco

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation considers the relationship between Brazilian instrumental music, U.S. jazz, and Brazilian national identity from the early twentieth century to the present. Though the time frame is broad, the present work uses nationalism as an anchoring point through which I analyze multiple musical genres. Previous works have primarily examined songs and lyrics, particularly during the military dictatorship (1964-85), when words against the regime were censored and songwriters persecuted. However, listeners and musicians of instrumental music also engaged with discourses of national identity in profound terms before, during, and after this period, posing ideals of Brasilidade against cultural productions abroad, …

Safety And Optimality Monitors For Learning-Enabled Systems Using Conformal Prediction, Jackson Cox

McKelvey School of Engineering Graduate Student Theses & Dissertations

The use of machine learning to create data-driven plant models and controllers has led to an increased need for safety and optimality monitors for model-based systems. System plant models are subject to uncertainty due to learning constraints such as unseen data and overfitting or physical constraints such as unknown dynamics and noise. This uncertainty is detrimental to safety-critical systems and must be properly regulated. To curb this uncertainty, we create prediction sets using the guarantees provided by Conformal Prediction. With a user-specified high probability, these prediction sets contain the true plant system states for an entire prediction horizon, which we …

Capacity-Weighted Figures-Of-Merit For Battery Transport Metrics, Cj Sturgill, Christopher Sutton, Julian Schwenzel, Morgan Stefik

Faculty Publications

New battery materials with improved transport are needed. Typical measurements yield widely varying voltage-dependent diffusivities and reporting practices are diverse. Some materials (e.g. first-order phase change) have most redox occur at a specific voltage and may be sufficiently represented by singular transport metrics. Many rapid intercalation materials, however, exhibit second-order phase transitions with redox over a broad voltage range. How should such cases be compared? The use of capacity-weighted average values is suggested where voltage-dependent metrics are consolidated into representative descriptors as figures-of-merit. Examples are elaborated where differential capacity (dQ/dV) is used to derive a …
