We present high-resolution (0 (Formula presented) .″ 94 ≈ 55 pc) Atacama Large Millimeter/submillimeter Array (ALMA) CO(2–1) and¹³CO(2–1) observations of the highly inclined ( (Formula presented) i∼87.°5 ) galaxy NGC 4565 covering out to galactocentric radius R_gal ≳ ± 17 kpc. The combination of sensitivity and resolution enables the detection of CO emission well into the H i-dominated outer disk while isolating individual molecular clouds across the full extent of the galaxy. Although often described as an edge-on Milky Way analog, the molecular gas profile of NGC 4565 has a central gap that is more similar to …

The Regulatory Costs Of Wine Production In Napa County, Lynn Hamilton, Michael Mccullough

Agribusiness

Unlike other food products, commercial alcoholic beverage production has been subject to federal regulation and taxation since the founding of the United States, with specific wine taxes being levied during the wartime Emergency Revenue Act of 1914 (Cilluffo and Gravelle, 2024). Since then, taxation and regulations have expanded, with many new laws originating at the state level. Additional regulatory costs, combined with the current decline in consumer demand raise questions regarding the long-term viability of California wine production. Napa County Farm Bureau contacted Cal Poly to assess baseline conditions in the industry by conducting a case study of regulations accruing …

Nascent Titanium-/Silicon-Containing Particle Formation In Corona-Discharge-Assisted Combustion, Chanakya Bagya Ramesh, Frank Daoru Han, Yang Wang

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Adding plasmas to a flame has been shown to introduce high concentrations of charges, ions, and radicals to the said flame. This technique of adding plasma to a flame is called plasma-assisted combustion (PAC), and this addition has been shown to make a flame more stable and efficient. At the same time, PAC has also been shown to alter particle formation during combustion. Here, we investigate the effect of a high-frequency (∼21 kHz) alternating current (AC) corona discharge on particle formation and growth in a premixed flame, especially at the initial stages (with particle sizes below 10 nm). We first …

Unveiling Corrosion Behavior And Passive Film Performance Of L12-Strengthened Ni28cr15cu8ti8fe26-Xco15+X Multi-Principal Element Alloys, Liran Huang, Zhiqiang Fu, Chenliang Chu, Shiyu Liu, Xiaohui Qin, Yunzhu Shi, Yongxiang Tan, Haiming Wen

Materials Science and Engineering Faculty Research & Creative Works

L12 precipitates are usually induced into face-centered cubic (FCC) multiple-principal element alloys (MPEAs) to improve their moderate yield strength; however, the precipitation also influences the corrosion resistance. This study investigated the corrosion behavior and passive film performance of a series of L1₂-strengthened Ni₂₈Cr₁₅Cu₈Ti₈Fe_26-xCo_15+x (x = 0, 3, 6, and 9 at.%) MPEAs in 3.5 wt.% NaCl solution. The size and density of the L1₂ nanoprecipitates were regulated via tuning Fe and Co content. With decreasing Fe/Co ratio, the radii of these nanoprecipitates gradually increased within the …

Evaluating Variety- And Market-Class-Specific Effects Of Dietary Pulses On Human Health, Jiayu Tang

Department of Food Science and Technology: Dissertations, Theses, and Student Research

While pulses are globally recognized for their high levels of dietary fibers, protein, and polyphenols, research often focuses on characterizing the physiological effects of a single variety. This approach overlooks the substantial genetic and compositional diversity that exists across pulse varieties and individual market classes, which can differ extensively in nutrient content and structure. These compositional differences have the potential to produce distinct physiological and microbial responses in humans, yet variety- and market-class-specific effects remain poorly characterized.

This thesis uses two complementary research methodologies to investigate the health-relevant effects of different pulse varieties and market classes, providing foundational knowledge to …

Evaluating Relationships Between Immunometabolism And Excess Adiposity Using Anthropometric And Body Composition Measurements, Corina Grimaldo

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Metabolic dysfunction is a key contributor to the development of chronic disease and is associated with excessive adiposity. Though body mass index (BMI) is a common screening tool used to identify possible metabolic dysfunction, it does not consider fat distribution. Other tools are needed to assess body composition and determine fat distribution. In recent studies, it has been suggested that alterations in metabolic processes may occur prior to a clinical diagnosis, and the combination of body composition and blood-based markers can help identify those early changes. The overall objective of this study is to identify low-cost indicators of metabolic dysregulation …

High-Resolution Lidar Observations For Coupled Effects Of Dry-Air Entrainment And Haze-Cloud Interactions On Cloud Vertical Structure, Jae Min Yeom, Suryadev Pratap Singh, Fan Yang, Hamed Fahandezh Sadi, Jesse Anderson, Yong Meng Sua, Manikandan Rajagopal, Steven Krueger, Will Cantrell, Raymond Shaw

Michigan Tech Research Data

Clouds act as crucial regulators of the Earth's radiation budget by reflecting shortwave solar radiation and absorbing longwave thermal emission. However, they continue to represent a major source of uncertainty in the climate models due to the subgrid-scale processes of cloud microphysics. A particularly complex mechanism is dry-air entrainment at cloud boundaries, which alters local supersaturation levels and drives droplet activation-deactivation cycles. Despite its significance, capturing these fast, small-scale processes remains an ongoing challenge.

In-situ airborne instruments provide only localized, intermittent spatial sampling along flight paths, whereas traditional ground-based remote sensing techniques lack the fine spatial resolution necessary to observe …

La Ciencia Hermanada Con El Arte”: El Escultor Anatómico Laureano Coll Soler (1856–1916), Chloe Sharpe

Artículos científicos

Este artículo examina la figura y la obra del escultor anatómico Laureano Coll Soler (1856–1916), uno de los principales representantes de la escultura anatómica en España en la segunda mitad del siglo xix. En un contexto en el que los modelos anatómicos tridimensionales desempeñaron un papel esencial en la enseñanza médica, España se distinguió por la contratación sistemática de escultores anatómicos en sus facultades de medicina, aunque estos profesionales recibieron un reconocimiento limitado y su producción ha sufrido procesos de pérdida y dispersión. A partir del análisis de fuentes de archivo inéditas, prensa histórica y diversas colecciones museísticas, el artículo …

Tales Of The Empathic Support Provider: How Emerging Adult Women Make Sense Of Providing Empathic Support To Female Friends, Emma R. Eslinger

Department of Communication Studies: Dissertations, Theses, and Student Research

The current study explored the stories and reflections of 33 emerging adult women who made sense of their empathic support provider (ESP) identity in the context of female friendships. From the standpoint of the retrospective storytelling heuristic, within communicated narrative sense-making theory, participants told stories about their ESP identity, including how they provide support to others and reflect on the benefits of drawbacks of serving in this role (CNSM, Koenig Kellas, 2022). Under Proposition 1 of CNSM theory, meanings, values, and beliefs (MVBs) that ESP women expressed in this role were depicted as key takeaways gathered. Findings illuminated how ESP …

Doctor Decision Making And Patient Outcomes, Janet Currie, W. Bentley Macleod, Kate Musen

Cowles Foundation Discussion Papers

Doctors often treat similar patients differently, which affects health outcomes and medical spending. We assess the recent literature on doctor decision making through the lens of a model that incorporates diagnostic and procedural skills, beliefs, incentives, and differences in patient pools. Decision making is affected by beliefs, training, experience, peer effects, financial incentives, and time constraints. Interventions to improve decision making include providing information, guidelines, and technologies like electronic medical records and algorithmic decision tools. Economists have made progress in understanding doctor decision making, but applications of that knowledge to improving health care are still limited.

Impacts Of Climate Hazards On Employment And Earnings By Hazard Type, Industry, Race, And Ethnicity, Dania V. Francis, Keren M. Horn

Sustainable Solutions Lab

We examine the relationship between climate-related disasters and subsequent county-level aggregate employment and earnings. We combine earnings and employment data from 2000 to 2023 with data on disasters to estimate local projection impulse response functions relating extreme disaster events to cumulative percent changes in employment and earnings. On average, disasters appear to reduce employment growth three to five years post disaster. There are small positive impacts on earnings. These results are largely driven by responses to hurricanes and tropical storms. Key rebuilding industries such as construction see short-term gains in employment that turn to losses in the longer-term that are …

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

Doctor of Nursing Practice Posters and Presentations

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 …

Antibody-Oligonucleotide Conjugates: An Emerging Modality For Precision Rna Therapeutics, Chen-Hsu Yu, Summer Y Y Ha, Zhiqiang An, Kyoji Tsuchikama, Wenbo Li

The Brown Foundation: Institute of Molecular Medicine

RNA-targeting therapeutics have enormous potential to precisely target disease-causing RNAs, extending beyond the traditional limits of "druggability" for small molecules, antibodies, and protein-targeting cell therapies. However, one crucial limitation is that RNA-targeting drug modalities (such as oligonucleotides) cannot effectively reach diseased tissue or cell types. Antibody-oligonucleotide conjugates (AOCs) emerge as a promising frontier in aiding RNA therapeutics by harnessing antibodies to deliver drug modalities to target specific RNAs in desired tissues or cells. In this Review, we summarize the critical components of AOCs, key considerations for their design and manufacturing, ongoing AOCs in preclinical/clinical development, and disease indications. We discuss …
