Patient-Specific Quality Assurance Of Dynamically-Collimated Proton Therapy Treatment Plans, Alonso Gutierrez, Eduardo Pons, Andrew Wroe

All Publications

Background: The dynamic collimation system (DCS) provides energy layer-specific collimation for pencil beam scanning (PBS) proton therapy using two pairs of orthogonal nickel trimmer blades. While excellent measurement-to-calculation agreement has been demonstrated for simple cube-shaped DCS-trimmed dose distributions, no comparison of measurement and dose calculation has been made for patient-specific treatment plans.

Purpose: To validate a patient-specific quality assurance (PSQA) process for DCS-trimmed PBS treatment plans and evaluate the agreement between measured and calculated dose distributions.

Methods: Three intracranial patient cases were considered. Standard uncollimated PBS and DCS-collimated treatment plans were generated for each patient using the Astroid treatment planning …

Automatic-Adjusting Drip Chlorination System Without Electricity, Brian Genet Sep 2024

Automatic-Adjusting Drip Chlorination System Without Electricity, Brian Genet

Master's Theses and Capstones

Developing countries often use open-source water including groundwater, snowmelt, and springsas the primary source of their drinking water. These water sources increase the risk of contamination from bacteria and pathogens from nearby humans and animals. Ingestion of contaminated water can cause illnesses, and in extreme cases, death. While the technology to decrease or even eliminate the risk of contamination in drinking water exists, most of these methods require electricity, which is not necessarily readily available or sustainable in developing countries. The objective of this study is disinfection without electricity as a means to provide disinfected drinking water to developing countries. …

The Law Is Weirder Than Ai, Sam Williams Sep 2024

The Law Is Weirder Than Ai, Sam Williams

Hofstra Law Review

Between artificial intelligence threatening to take our jobs and destroy the world while adopting the aesthetic of the weird and a presidential election that could have been partially determined by how people feel about being weird, it seems like the weird is taking over. In this Article, I make the case for embracing the weird. Only by embracing our own weirdness can we make sense of the weirdness (or lack thereof) of those that we do not understand. Primarily through the lens of author H.P. Lovecraft’s weird tales, I argue that the law is very weird. This weirdness is mostly …


Numerical Analysis Of The Mechanics Of Foreign Particle Entry On Automotive Turbocharger Compressor Blades, Anand Pai, Anshul Singh, Marcos Rodriguez-Millan, Adwait Mangrule Sep 2024

Numerical Analysis Of The Mechanics Of Foreign Particle Entry On Automotive Turbocharger Compressor Blades, Anand Pai, Anshul Singh, Marcos Rodriguez-Millan, Adwait Mangrule

Open Access archive

Automotive turbochargers, essential for enhancing intake air pressure and boosting torque in internal combustion engines, operate at exceptionally high rotational speeds of approximately 100,000 to 300,000 rpm. Despite the implementation of dual or triple air filtration systems to filter contaminants, neglected maintenance can lead to clogged filters, resulting in the ingestion of metallic filter mesh, and other small-sized objects from filter indicators, washers, and plastic components into the turbocharger assembly. The current study explores the impact of foreign particles on the mechanics of turbocompressor impeller blades in automotive turbochargers through a computational approach. A finite element model of the turbocompressor …


Engineering-Enhanced Theatre: How Engineering Involvement Can Aid Regional Theatres, Albert M. Le Sep 2024

Engineering-Enhanced Theatre: How Engineering Involvement Can Aid Regional Theatres, Albert M. Le

Architectural Engineering

Engineering and theatre are disciplines not often associated with each other within regional and small theatre companies in the United States. The distinction between the two fields of study is not simply from the fundamental differences between how each field is taught and practiced, but also the difficulties encountered within a scope of theatre often constrained with limited budget and time for each production. However, when beginning to explore the intersection between engineering and theatre, it is found that the empirical nature of current theatrical practices can be countered, and scenic design and construction can be re-envisioned with engineering involvement …

Innovations To Increase Plywood Shear Wall Design Capacity And Resiliency, "Mega Walls", Through Ductile Metal Strapping, Trevor Douglas Reichenberg, Tara Suzanne Reich, Katelyn Marie Lowry

Architectural Engineering

The researchers of this project are three undergraduate Architectural Engineering students at California Polytechnic State University, San Luis Obispo. Plywood shear walls are common structural elements in timber structures that resist lateral forces. Since their introduction to the industry in the 1950s, their shear capacities have remained essentially unchanged amongst the innovations of other wooden lateral systems. Prior to this project, Cal Poly undergraduate researchers have taken on the challenge of modernizing the shear wall. The “MeGa Wall” project was born: a system that implements metal gauge strapping which enhances a conventional wall by reducing nail connection failures. Full-scale experimental …

Along For The Journey: Graduate Student Perceptions Of Research, Alissa A. Droog, Kari D. Weaver, Frances Brady Sep 2024

Along For The Journey: Graduate Student Perceptions Of Research, Alissa A. Droog, Kari D. Weaver, Frances Brady

Faculty Articles, Papers, and Other Scholarship

Graduate students’ identities and personal lives are heavily tied to their experiences of research, and many struggle to find, understand, and use information for research purposes. Using a drawing exercise rooted in visual research methods combined with semi-structured interviews, a research team in the United States and Canada explored graduate student perceptions of research with nineteen participants. Thematic analysis identified six themes: research is abstract; research is an odyssey; social support makes or breaks the student experience; research is an emotional continuum; interplay between identity/values; information is problematic. The study has implications for how librarians support graduate student research.

Association Of Glp-1 Receptor Agonists And Hepatocellular Carcinoma Incidence And Hepatic Decompensation In Patients With Type 2 Diabetes, Lindsey Wang, Nathan A. Berger, David C. Kaelber, Rong Xu

Faculty Scholarship

Background & aims: Hepatocellular carcinoma (HCC) is a leading cause of cancer death. HCC is preventable with about 70% of HCC attributable to modifiable risk factors. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), Food and Drug Administration–approved medications for treating type 2 diabetes mellitus (T2DM), have pleiotropic effects on counteracting risk factors for HCC. Here we evaluate the association of GLP-1RAs with incident HCC risk in a real-world population. Methods: This retrospective cohort included 1,890,020 patients with a diagnosis of T2DM who were prescribed GLP-1RAs or other non-GLP-1RA anti-diabetes medications and had no prior diagnosis of HCC. Incident (first-time) diagnosis of HCC …


Settlement As Construct: Defining And Counting Party Resolution In Federal District Court, Charlotte S. Alexander, Nathan Dahlberg, Anne M. Tucker Sep 2024

Settlement As Construct: Defining And Counting Party Resolution In Federal District Court, Charlotte S. Alexander, Nathan Dahlberg, Anne M. Tucker

Northwestern University Law Review

Most civil cases settle. Yet generating a definitive settlement rate presents complex definitional and empirical problems, both in what should count as a settlement and how to count it. This Essay makes three contributions to better understanding and defining settlement. First, we propose a flexible, empirically informed, operationalizable definition of settlement as party resolution. Second, we exploit a new federal litigation data source to count party resolutions using machine learning models trained on 11 million docket sheet entries. Third, we offer new findings on party resolution frequency and distribution in the federal courts. Settlement is more widely and differently deployed …

Organizations play a central role in replicating societal inequalities. Despite theories of gendered and racialized organizations, evidence of unequal outcomes, and research on proposed mechanisms, we have few intersectional analyses demonstrating how the promotion process varies by race and gender across job levels in actual organizations. In this first-ever analysis of advancement in a U.S. firm by gender, race, and job, we run random effects logistic regression models on five years of novel longitudinal data from the software engineering workforce of a U.S.-based technology company. Results show intersectional performance-reward bias in patterns that help maintain the racialized gendered hierarchy so …

Geology Faculty Publications and Presentations

Regional-scale characterization of shallow landslide hazards is important for reducing their destructive impact on society. These hazards are commonly characterized by (a) their location and likelihood using susceptibility maps, (b) landslide size and frequency using geomorphic scaling laws, and (c) the magnitude of disturbance required to cause landslides using initiation thresholds. Typically, this is accomplished through the use of inventories documenting the locations and triggering conditions of previous landslides. In the absence of comprehensive landslide inventories, physics-based slope stability models can be used to estimate landslide initiation potential and provide plausible distributions of landslide characteristics for a range of environmental …
