This paper will describe three different existing placement systems at each of our liberal arts institutions as well as the affordances and constraints of each approach. Further, we analyze data …

The Sonora Substellar Atmosphere Models. V. A Correction To The Disequilibrium Abundance Of Co2 For Sonora Elf Owl, Nicholas F. Wogan, James Mang, Natasha E. Batalha, Kevin Zahnle, Sagnick Mukherjee, Channon Visscher, Jonathan J. Fortney, Mark S. Marley, Caroline V. Morley

Faculty Work Comprehensive List

To aid the interpretation of observations of substellar atmospheres, S. Mukherjee et al. created the Sonora Elf Owl grid of model atmospheres, simulations that accounted for disequilibrium quench chemistry. However, Sonora Elf Owl did not accurately estimate CO₂ quenching because the models quenched the gas with respect to the full atmosphere equilibrium, but CO₂ should have instead been quenched with respect to the disequilibrium (i.e., quenched) abundance of CO. As a result, Sonora Elf Owl under-predicted the CO₂ abundance by several order of magnitude in some instances, an amount that JWST is sensitive to. Here, we release …

Whole-Brain Mapping Of Neuronal Interleukin-1 Tpe 1 Receptor In The Mouse Brain, Gabriella Maxey

Harriet L Wilkes Honors College Theses 2020 - Present

The pro-inflammatory cytokine interleukin-1 (IL-1) has diverse functions within the brain such as facilitating memory and regulating sleep, yet is linked to various psychopathological disorders including depression, anxiety, and PTSD. The IL-1 type 1 receptor (IL-1R1) is the sole receptor of IL-1 and is predominantly expressed on non-neuronal cell types in the brain; however, the existence of IL-1R1 on neurons has been debated due to inconsistent mapping attempts. Here, we generated a specific atlas of neuronal IL-1R1 (nIL-1R1) distribution throughout the brain in global and glutamatergic-neuron-specific IL-1R1 reporter mice. Using immunohistochemical labeling and the QUINT workflow, we show nIL-1R1 is …

“Just Broken Rocks” The Lower Colorado River Through The Lens Of The Coastal Migration Theory, Ruth Musser-Lopez

Electronic Theses, Projects, and Dissertations

My thesis is that archaeological evidence from the Havasu Landing Site (CA-SBR-1456) in San Bernardino County, California, supports the Coastal Migration Theory (CMT) proposed by Davis and Madsen (2020). The CMT suggests that humans followed the Pacific coastline to America during the Last Glacial Maximum (LGM), approximately 24,000 years ago (Erlandson 2024). I examined the site’s minimally modified cobbles, described as “just broken rocks,” confirming them to meet the definition of “creative minimization tools,” a criterion of the CMT. I found clustering of the minimization and other atypical stone tools with siliceous blade cores representing a 30,000-year-old East Asian technology …

A Mineralogical And Geochemical Investigation Of The Influence Of Tectonic Setting On Accessory Mineral Assemblages In Serpentinites Along The Western North American Margins, Bryan H.T. Seymour

Electronic Theses, Projects, and Dissertations

Serpentinites are metamorphic rocks typically produced by hydrating mantle peridotites to form assemblages containing one or more serpentine minerals. They occur in various tectonic and geologic settings, such as submarine hydrothermal systems, ophiolite sequences, and the forearc mantle. Serpentinites are associated with highly reduced conditions, as indicated by low oxygen fugacity (ƒO₂) values. Previous investigations suggest that oxygen fugacity varies with tectonic setting due to differences in environmental conditions. To test this hypothesis, we analyzed serpentinites from a wide variety of tectonic settings in western North America: The New Idria forearc diapir (CA), Canyon Mountain Island arc complex (OR), Josephine …

Investigating The Role Of The Hypocretin/Orexin System In A Novel Model Of Polysubstance Dependence, Tyler Zarin

Electronic Theses and Dissertations

Substance use disorders (SUD) in the United States are steadily increasing. Potent and dangerous substances such as methamphetamine (MA) and fentanyl (FEN) are often co-used as a polysubstance (POLY), either intentionally or unknowingly as FEN is a common adulterant. SUD is characterized by physiological and psychological dependence involving the negative reinforcement of anhedonia and withdrawal which drive hypermotivated drug-taking behaviors. Current theory suggests that recruitment of hypocretin/orexin (HCRT) neuropeptide in reward and stress associated brain regions contributes to drug dependence. Despite strong evidence for HCRT’s role in mono-drug dependence, a relevant model for POLY dependence has yet to be developed, …

The Right To Grow Old, Jamal Greene

Faculty Scholarship

This chapter considers the status of a constitutional “right to grow old” under the US Constitution. Understood as a “positive” right – ensuring a certain minimum quality of life to people as they face the challenges of aging – such a right may seem unavailing given the austerity in respect to such rights that many lawyers associate with the US constitutional tradition. This chapter shows this view to be premature, at least. Unlike the kinds of positive rights overtly rejected in prior cases, such as rights to certain forms of social welfare or to racial equality, a right to grow …
