3d Electromagnetic Simulations Of A 1.6 Cell S-Band Photoinjector: Emittance Studies For Electron Microscopy, Trudy Bolin

Electrical and Computer Engineering ETDs

Modern beam-based materials research demands electron sources with increasingly precise time resolution, high brightness, and stability. For example, there are various instruments across the U.S. dedicated to ultrafast electron diffraction (UED), but fewer are dedicated to ultrafast electron microscopy (UEM), which demands beam stability. Modeling femtosecond electron bunches with ultra-low emittance < 50 nm-rad inside a 1.6-cell S-band (2856 MHz) rf photoinjector with full 3D electromagnetic simulations can require high-performance computing (HPC) environments due to the scale disparity between the macroscopic cavity geometry and the femtosecond-scale bunch kinematics. To enable optimization in a desktop computing environment, this work presents a streamlined 3D electromagnetic Particle-in-Cell (PIC) simulation framework optimized for 400-femtosecond bunch regimes. The covariance method was employed to study emittance properties for electron bunch counts ranging from thousands to millions and has successfully resolved highly transient, pure rf phase-space rotations, such as a localized energy-spread minimum occurring at the gun exit iris. To overcome the computational cost of these simulations, a machine-learning-based Bayesian optimization approach was deployed to construct multi-objective Pareto fronts from sparse datasets. Because the simulation software is scalable from desktop to HPC facilities, the framework is ready for experiments at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (LBNL).

Real-Time Waveform Synthesis For Rfsoc-Based Quantum Control Systems, Tiamike I. Dudley

Electrical and Computer Engineering ETDs

RFSoCs are gaining adoption in many labs for quantum control systems thanks to their compactness and affordability. Making full use of the many components on an RFSoC evaluation board is a challenging engineering problem that must be solved to realize scalable control systems. In this dissertation, I evaluate the performance of various RFSoC components in the context of quantum information science. I present two custom FPGA engines that accelerate and parallelize arbitrary waveform generation. The first engine can be instantiated many times to power low-speed DACs for ion-shuttling trap electrodes. The second engine synthesizes CPMG-XY8n dynamical decoupling pulse sequences on …

Simulations Of Atmospheric Pressure Streamer Discharges: Mechanisms Of Streamer Propagation And Related Physics, Dejan Nikic

Electrical and Computer Engineering ETDs

Gas discharge simulations are performed with particular focus on photoionization process in a positive streamer discharge. The effects of this process are investigated by isolating the change in photoionization mean free path (MFP) and keeping the additional processes constant. Furthermore, comparison are made between various effects of simulation parameters, such as initial conditions, geometry extent, simula- tion particle count etc. All of these simulations are performed using a modern Direct Simulation Monte Carlo Particle-in-Cell (DSMC-PIC) code developed by Sandia Na- tional Laboratories. Large scale simulations including 1 cm and 5 cm electrode gaps are performed under standard atmospheric condition air. …

A Significant Moment In The Colorado River Water Supply Crisis, Jack Schmidt, Anne Castle, John Fleck, Eric Kuhn, Kathryn Sorensen, Katherine Tara

The Traveling Wilburys of the Colorado River

On Sunday, July 12, the surface of Lake Powell was 3524.32 feet above sea level, and the surface of Lake Mead was at 1042.77 ft.7 These elevations equated to 5,505,869 and 7,169,640 acre feet (af), respectively, of live storage in the two reservoirs. The combined total live storage of these reservoirs was 12,675,509 af. The last time the combined total live storage in Lake Powell and Lake Mead was this small was May 23, 1957, during construction of Glen Canyon Dam when the entire amount of 12,668,000 af was stored in Lake Mead.

Inactive Nurses In New Mexico: Insights Into License Lapse And Inactive Reserve Status, Kiyoko Dell Davis

Doctor of Nursing Practice Scholarly Projects

Nursing shortages have varied over the decades, yet persist at local, national, and global levels. Nurses report leaving the workforce for many reasons, including professional environment factors resulting from these shortages, further exacerbating a shrinking workforce and population growth. Recent efforts include recruitment and education incentives and implementation of the New Mexico Board of Nursing (NMBON) Inactive Reserve Licensure option, which allows retiring nurses to maintain a reduced-scope nursing license with fewer barriers. Despite these efforts, questions remain: why are nurses in New Mexico leaving the profession and would this licensure category have impacted retention? The purpose of this project …

Improving Continuity Of Care: Evaluating Universal Nursing Handoff Sheets, Elizabeth Ifeloluwa Sanya

Doctor of Nursing Practice Scholarly Projects

Effective communication during nursing handoffs is essential for safe, patient-centered care, as breakdowns in communication are a leading cause of adverse patient outcomes. At a large academic level I trauma center, inconsistent nursing handoff practices were identified across progressive care units following the COVID-19 pandemic. This variability contributed to incomplete transfer of patient information and was associated with increased patient safety incidents, including delayed wound care, central line dressing lapses, and medication errors involving high-alert therapies. The purpose of this DNP project was to plan, implement, and evaluate the use of  standardized nursing handoff sheet and its impact on continuity …

Trial By Fire: Disaster Justice And Lessons Learned, Clifford Villa

Faculty Scholarship

Disaster Justice reflects the intersection of environmental justice and disaster law. The study of disaster justice is becoming increasingly essential as disasters become more frequent and devastating in the face of accelerating climate change. Disaster law is marked by statutes such as the federal Stafford Act and by theory such as the “disaster cycle” of readiness, response, and recovery. Environmental justice recognizes that the distribution of harms such as bad air or water quality may be distributed inequitably among groups such as low-income populations or racial minorities. In similar fashion, the adverse impacts of disasters may also be distributed inequitably …

Memoria Selectiva Y Resistencia Identitaria En La Lluvia Amarilla (1988) De Julio Llamazares, Alain Pérez Martínez

Intersecciones Hispánicas: Revista de Cultura, Literatura y Lingüística

Este ensayo analiza la novela La lluvia amarilla de Julio Llamazares a través del concepto de memoria selectiva como mecanismo de resistencia frente a la desaparición personal y colectiva. El protagonista, Andrés, el último habitante de Ainielle, reconstruye su pasado mediante recuerdos marcados por ausencias: las de su esposa Sabina, su hijo muerto y su amigo Camilo. Estas voces ausentes no son simples evocaciones, sino presencias activas que habitan su conciencia y moldean su percepción del presente. En este contexto, la memoria no se presenta como un archivo fiel, sino como una reconstrucción subjetiva que permite resistir el olvido, prolongar …

“El Hijo Del Vampiro”: Crítica A La Tradición Y Al Sistema Patriarcal, Arely Orozco Ramirez

Intersecciones Hispánicas: Revista de Cultura, Literatura y Lingüística

“El hijo del vampiro” de Julio Cortázar es una obra gótica que enmarca y destaca las características del vampiro clásico dentro de la literatura. A través del cuento, Cortázar crítica al sistema patriarcal mediante personajes como Duggu Van, símbolo del patriarcado, el cual abusa sexualmente de Lady Vanda. La violencia física, sistemática y simbólica son ejecutadas por dicho personaje a lo largo del cuento. La historia refleja cómo los roles de género tradicionales perpetúan la misoginia, y cómo esta es heredada en el hijo vampírico, fruto de la violación entre Duggu Van hacia Lady Vanda.

El Forastero Y El Culto: H.P. Lovecraft In The Work Of Mariana Enríquez, Griffin Carty

Intersecciones Hispánicas: Revista de Cultura, Literatura y Lingüística

Este artículo examina dos cuentos de Mariana Enríquez: “Bajo el agua negra” y “Las cosas que perdimos en el fuego”, y sus conexiones a dos cuentos de H.P. Lovecraft: “Shadow over Innsmouth” y “The Thing on the Doorstep”. Este ensayo argumenta que Enríquez usa los tropos lovecraftianos deliberadamente para expresar sus ansiedades modernas sobre el extractivismo, clasismo, y violencia del género, en contraste directa de las ansiedades de Lovecraft sobre la integración racial y el miedo del Otro étnico, económico, y femenino. La primera comparación es la del horror del género de “Las cosas que perdimos en el fuego”, que …

When Justice Fails: Female Vengeance And Indigenous Memory In Jayro Bustamante’S Film La Llorona (2019), Isabel Ibáñez De La Calle

Intersecciones Hispánicas: Revista de Cultura, Literatura y Lingüística

Jayro Bustamante’s film La Llorona (2019) reimagines the Latin American myth of the weeping woman to expose the failures of state justice and propose a feminist, decolonial alternative rooted in Indigenous memory and spiritual retribution. The film follows retired general Enrique Monteverde, modeled after Guatemalan dictator Efraín Ríos Montt, as he is tried for genocide against the Maya Ixil people. While the courtroom scenes depict a moment of accountability, they ultimately reveal how legal institutions remain complicit in protecting power. In contrast, the arrival of Alma—an Indigenous domestic worker who embodies La Llorona—introduces a supernatural force that intervenes when the …

A Multimodal Analysis Of Conflicting Discourses On New Mexican Identity, Nicholas L. Chavez, Fátima Holguín

Intersecciones Hispánicas: Revista de Cultura, Literatura y Lingüística

We analyze two contrasting discourses on New Mexican identity, as represented in political cartoons from Trever (2021) and García (2018). We show how visual and linguistic elements of the cartoons work together to construct identity through metaphor and metonymy. It was found that Trever (2021) relied on cultural symbols such as the Zia Sun symbol as metonyms for various aspects of New Mexico’s identity, while García (2018) subverted established metaphors for American culture such as the melting pot and Uncle Sam to critique governmental influence on Nuevomexicano (‘New Mexican’) identity formation. Using the critical discourse analysis framework of Fairclough (1995), …

Rejecting Salinas V. Texas’S Catch-22: Towards State Constitutional Protections For Silence In New Mexico, Kayla Herring

New Mexico Law Review

The landmark United States Supreme Court case, Miranda v. Arizona, protects individuals’ constitutional rights in coercive environments, like custodial interrogations, where law enforcement officers apply immense psychological pressure through specialized techniques. However, subsequent caselaw distorts Miranda’s intent to enable prosecutors to comment on silence. Doing so divorces Miranda from the reason the United States Supreme Court established Miranda warnings in the first place. This subsequent caselaw narrows individuals’ constitutional right against having their silence used against them in later criminal proceedings to imply guilt based on the custodial framework established in Miranda. Salinas v. Texas is one of those subsequent …
