We present timing and spectral analyses of Neutron star Interior Composition Explorer (NICER), Nuclear Spectroscopic Telescope Array (NuSTAR), and IXPE observations of the magnetar 1E 1841−045 covering 82 days following its 2024 August bursting activity as well as radio observations utilizing MeerKAT and Effelsberg. We supplement our study with a historical NuSTAR observation and all 2024 preoutburst NICER observations. The outburst is marked by an X-ray flux enhancement of a factor of 1.6 compared to the historical level, predominantly driven by a newly formed nonthermal emitting component with a photon index Γ = 1.5. This flux showed a 20% decay …

The steady-state gamma-ray emission from the Sun is thought to consist of two emission components due to interactions with Galactic cosmic rays: (1) a hadronic disk component, and (2) a leptonic extended component peaking at the solar edge and extending into the heliosphere. The flux of these components is expected to vary with the 11 yr solar cycle, being highest during solar minimum and lowest during solar maximum, as it varies with the cosmic-ray flux. No study has yet analyzed the flux variation of each component over solar cycles. In this work, we measure the temporal variations of the flux …

Children’s Nutrition Research Center Staff Publications

PI3K inhibition causes apoptosis selectively in NOTCH1-mutant head and neck squamous cell carcinoma (HNSCC), but modest single-agent responses and acquired resistance (AR) limit the clinical efficacy of targeted agents. To address these limitations, we investigated novel combination therapies. We tested the efficacy of 5768 compounds as single agents and 139 in combination with PI3K inhibitors in sensitive and AR NOTCH1-mutant HNSCC cell lines. We generated synergy/efficacy classifications for the combinations using multiple metrics of statistical drug synergy and growth rate indices. The PLK1/PI3K combination's efficacy was validated using orthogonal in vitro methods and in two HNSCC xenograft models. Compound efficacy …

It Shucks To Be Inbred: Effects Of Small Population Sizes On Genomic Diversity Of Hatchery Reared Olympia Oysters (Ostrea Lurida), Anna S. Heasley

Master's Theses

Olympia oysters (Ostrea lurida), critical members of estuarine ecosystems along the California Current Ecosystem (CCE), have faced significant population declines due to historical overfishing and habitat deterioration. Today, managers from multiple estuaries across the CCE are focusing on conservation aquaculture breeding efforts to aid in restoration; however, the genetic implications of these efforts remain unexplored. As with other Ostrea spp, Olympia oysters have a viviparous reproductive strategy that creates unique challenges for aquaculture-mediated restoration. This study evaluates the genetic impact of current captive breeding practices on Olympia oyster cohorts produced in three California estuaries: Elkhorn Slough (EHS), Morro Bay (MB), …

Environmental Science and Management Faculty Publications and Presentations

Understanding how water moves through a watershed is one of the most fundamental yet often complicated aspects of hydrology, especially in urban areas. Urban infrastructure and water management alter natural hydrological pathways in developed watersheds, which can violate assumptions of a watershed approach to ecosystem science. We focus on two aspects of urban landscapes that often create challenges to model watershed processes within and among urban areas: (1) accurate delineation of urban flow paths and (2) consistent characterisation of the urban landscape within and among cities. Here, we describe these challenges and identify how certain components of these challenges can …

Balancing Act: Corporate Governance And Biodiversity Conservation In Extractive Sector, Ammad Ahmed, Hoa Luong, Abiot Tessema

All Works

Extractive industries such as mining and oil extraction drive habitat loss, soil erosion, water pollution, and biodiversity decline. While prior research has examined corporate environmental performance in these sectors, little is known about how internal governance mechanisms, particularly equitable shareholder treatment, relate to biodiversity outcomes. Drawing on legitimacy theory, which holds that fair treatment signals genuine commitment to societal expectations, strengthens a firm's social license, and motivates environmental stewardship, this study examines whether equitable shareholder practices promote biodiversity conservation. Using US and Canadian extractive firms from 2006 to 2020, we find that fair shareholder treatment is positively associated with better …

Advancing Generative Ai For Music With Photonics, Eduardo Miranda, Siegelwax Brian

School of Art, Design and Architecture

This paper presents PhotoSing, a system that learns to generate polyphonic tunes by extracting sequencing rules from given examples. We developed a method to encode given pieces of music in terms of unique musical events, referred to as UMEs, and stochastic rules for sequencing them. Those rules are subsequently converted into representations to be processed by a photonic computer to generate new compositions. This research builds upon a previous system, QuSing, which generated monophonic tunes with superconducting quantum computing. The paper discusses the pitfalls of the previous system, the research and the solutions developed to improve them. It details the …

Paradoxical Forms Of Scientific Heroism When Responsibly Conducting Research, Theresa A. Thorkildsen

Heroism Science

The Stanford Prison Experiment is widely known for offering insight into the responsible conduct of research as well as how prisoners and prison guards fall easily into potentially harmful roles. As the principal investigator of the study, Philip Zimbardo became a polarizing figure in the social sciences -- both celebrated as a pioneering hero and criticized for ethical shortcomings -- while consistently engaging with his critics throughout his career (Zimbardo, n.d.). Highlighting Zimbardo’s influence on the protection of human research participants, this article uses details from Zimbardo’s self-reflections and insights on the paradoxes of heroism to convey how research personalities …

Embedding Self-Determination In Transition Planning For Young Adults With Autism, Kade Lane

Graduate Teacher Education

Despite decades of legal mandates under the Individuals with Disabilities Education Act (IDEA), students with autism spectrum disorder (ASD) continue to face disproportionately poor postschool outcomes in employment, independent living, and higher education. Research consistently identifies self-determination as a critical predictor of positive adult outcomes, yet transition planning in many educational settings remains procedural, adult-driven, and disconnected from student agency. This capstone explores how self-determination can be meaningfully embedded into transition planning by synthesizing literature across legal foundations, structured interventions, culturally responsive practices, and implementation strategies. Grounded in Self-Determination Theory, the literature review reveals that student-led IEPs, autonomy-supportive instruction, and …

Impact Of Primary Preventive Initiatives To Reduce Burnout And Compassion Fatigue In Emergency Department Nurses, Kelley Molandes

Doctor of Nursing Practice (DNP) Manuscripts

Background and significance: It is estimated that 20% of nurses leave the profession within the first year due to an onset of burnout (Henson, 2020). Prior to the pandemic of 2020, workforce projected models estimated large-scale shortages in full time employee (FTE) registered nurses as demand continued to outpace supply (Lauer, 2022). Researchers estimate projections from 2024 into the year 2032 are now skewed, as pandemic-related contributors and their effects on burnout in the nursing profession have not been thoroughly assessed (Saravanan et al., 2022). When considering the data, an underlying need for burnout prevention amongst nurse residents emerges. Interventions …

Learning Labs As A Professional Development Model To Strengthen Special Education Literacy Instruction, Claire Krajkowski

Masters Projects

Special education teachers face unique challenges in delivering effective literacy instruction to students with disabilities, yet traditional professional development often remains disconnected from the realities of special education classrooms. These conventional models frequently lack opportunities for sustained collaboration, reflective practice, and the application of evidence-based strategies tailored to diverse learner needs. This project presents a comprehensive plan for designing and facilitating Learning Labs, a form of embedded professional development grounded in constructivist and sociocultural theories. The Learning Lab model emphasizes collaborative inquiry, pedagogically productive talk, and the analysis of authentic instructional artifacts to deepen teachers’ understanding of effective literacy instruction. …
