This is supporting data for a publication on the role of lily pads in contributing to the dissolved organic matter pool in Lake Louise, a small lake in the Pacific Northwest region of the USA. Specifically, this data includes the absorbance and fluorescence spectra of the Lake Louise water samples (taken weekly over the course of 2018). These files include large spreadsheets with raw and corrected absorbance and fluorescence intensity data as a function of wavelength, as well as the raw and corrected absorbance and fluorescence 3D excitation-emission matrix spectra (EEMs). These files are …

Electrocyclic reactions are characterized by the concerted formation and cleavage of both σ and π bonds through a cyclic structure. This structure is known as a pericyclic transition state for thermal reactions and a pericyclic minimum in the excited state for photochemical reactions. However, the structure of the pericyclic geometry has yet to be observed experimentally.We use a combination of ultrafast electron diffraction and excited state wavepacket simulations to image structural dynamics through the pericyclic minimum of a photochemical electrocyclic ring-opening reaction in the molecule α-terpinene. The structural motion into the pericyclic minimum is dominated by rehybridization of two carbon …
Identifiability Of Phylogenetic Models, Thomas J. Yacovone
Identifiability Of Phylogenetic Models, Thomas J. Yacovone
Math and Computer Science Honors Theses
An algebraic statistical model is a parametrized family of probability distributions. Identifiability is a crucial property of a statistical model; when it holds, probability distributions in the model uniquely determine the parameters that produce them. In phylogenetics, models that are identifiable can be used to ascertain evolutionary relationships between species based on observed data, such as amino acid and DNA sequence data. However, global identifiability is a strong condition that may not always hold. A discrete parameter of a model is said to be generically identifiable if the set of probability distributions that do not uniquely determine the discrete parameter …

Desal In So. Cal - Are We There Yet?, Luke F. Swanson
Master's Projects and Capstones
Southern California has access to a finite amount of water that is vulnerable to the state’s changing climate and growing population. The increasing population’s water demands and hydrologic variability due to climate change inspire different proposals to solve these water limitations. Seawater or brackish water desalination and wastewater recycling are all water resources that have the potential to help meet the water needs of Southern California, specifically the South Coast Hydrologic Region. Every water resource requires energy to transport, treat, and distribute the water for use; in an era of climate change, when energy use contributes to greenhouse gases, utilities …
Possible Impact Of Additives In Artificial Turf On Aquatic Life In The San Francisco Estuary, Elena Galkina
Possible Impact Of Additives In Artificial Turf On Aquatic Life In The San Francisco Estuary, Elena Galkina
Master's Projects and Capstones
The use of artificial turf fields as a replacement for natural turf has been increasingly promoted as a green solution to reduce water usage, maintenance costs, and the need for pesticides. However, the potential environmental impacts of artificial turf fields are poorly understood, particularly in the context of the San Francisco Estuary, which is one of the largest and most polluted estuaries in the United States. This paper investigates the potential contribution of artificial turf from sports fields to the microplastic and chemical pollution of the San Francisco Estuary during artificial turf’s use and maintenance life stage. The study synthesizes …
An Integrated Resource Plan For Tucson Electric Power Company, 2020-2050, Timothy Gary Sheehan Jr, Danny Alexander Zepeda
An Integrated Resource Plan For Tucson Electric Power Company, 2020-2050, Timothy Gary Sheehan Jr, Danny Alexander Zepeda
Master's Projects and Capstones
According to the Environmental Protection Agency, the United States electric power industry is responsible for 25% of the country’s greenhouse gas emissions. As a result, many utilities face state mandates which force electric utilities to reduce their emissions by decreasing reliance on fossil fuels. An Integrated Resource Plan (IRP) is the primary method by which electric utilities plan all aspects of future electricity supply and demand, presenting how the company will deliver reliable and affordable energy while meeting statutory requirements. We propose three IRP scenarios through 2050 for Tucson Electric Power (TEP), an electric utility in southern Arizona. The first …
Willow Abundance And Condition Mapping In Rocky Mountain National Park, Eric M. Nielsen
Willow Abundance And Condition Mapping In Rocky Mountain National Park, Eric M. Nielsen
Institute for Natural Resources Publications
Riparian and wetland willow species have undergone serious declines in Rocky Mountain National Park as a consequence of a variety of environmental changes and, most recently, damage resulting from moose overpopulation. To address concerns about the long-term status of willows in the park, we developed remote sensing-based raster maps of riparian and wetland willow species presence, canopy cover percentage, canopy height, and leaf area index. All outputs were produced at 3-meter resolution, and represent willows as they existed in 2021. The mapping was performed via random forests classification and regression models trained on several hundred vegetation plots from a variety …

Observation Of Robust Zero Energy Extended States, J. Ferdous, Cem Yuce, Andrea Alu, Hamidreza Ramezani
Physics and Astronomy Faculty Publications and Presentations
Topological edge states arise at the interface of two topologically distinct structures and have two distinct features: they are localized and robust against symmetry protecting disorder. On the other hand, conventional transport in one dimension is associated with extended states, which typically do not have topological robustness. In this letter, using lossy coupled resonators in one dimension, we demonstrate both theoretically and experimentally the existence of robust states residing in the bulk. We show that they are unusually robust against disorders in coupling between adjacent sites and losses. Our work paves the way to a different form of robust transport …

Development Of New Chemical Probes To Delineate The Polyamine Regulation & Molecular Strategies To Unravel Protein Polyamination, Vennela Tulluri
Theses and Dissertations
Polyamines such as putrescine, spermidine, and spermine modulate critical cellular processes, including gene expression and cell proliferation. Cellular polyamine regulation is a complex mechanism controlled by three different proteins: Ornithine decarboxylase (ODC), Antizyme (OAZ), and Antizyme Inhibitor (AZIN). While ODC is directly involved in polyamine biosynthesis, OAZ, and AZIN regulate the ODC activity via protein-protein interactions. The dysregulation of ODC, OAZ, and AZIN leads to elevated polyamines in numerous pathologies, making them attractive targets for controlling polyamine levels. Besides regulating polyamine synthesis, OAZ modulates polyamine transport. However, the precise mechanism remains elusive. In this research, we discuss our approach to …
