Inclusive Measurement Of Upsilon(4s) To Upsilon(1s) Decays With Belle Ii Data, John Wilson Stacy

Electronic Theses and Dissertations

An inclusive measurement of ϒ(4S) decays to ϒ(1S) is reported. Using 364.5 fb−1 of Belle II data collected at the ϒ(4S) center-of-mass energy, ϒ(4S) → ϒ(1S) decays are identified via a fit to the μ+μ− invariant mass spectrum. Backgrounds from initial state radiation production of ϒ(1S) are subtracted using a fit to 42.6 fb−1 of data collected below the ϒ(4S) center-of-mass energy. Using our models and values taken from literature, the inclusive branching ratio for inclusive ϒ(4S) decays to ϒ(1S) can be measured with a statistical uncertainty of 5.1% and a systematic uncertainty of 14.8%.

Furthermore, the nkuho and mbopo – as they are called in Efik and Ibibio respectively – are often analyzed and presented as one singular entity, in …

Dunc13 Isoforms, Rim, And Rab3 Differentially Modulate Ethanol Sedation Sensitivity In Drosophila Melanogaster., Gaurav Shrestha

Electronic Theses and Dissertations

Dunc13 is a Drosophila active zone protein homologous to the mammalian Munc13that interacts with RIM and Rab3 as a heterotrimer. Alcohol binds to the C1 domain of Dunc13/Munc13 and inhibits its ability to bind to Diacylglycerol, inhibiting neuronal signaling. The genetic reduction of Dunc13 activity in the Dunc13P84200/+ heterozygotes induces a state in flies that mimics alcohol tolerance, evidenced by increased self-administration, and behavioral, physiological, and molecular resistance. This includes changes in the expression of key synaptic proteins, such as decreased expression of Dunc13 and Syb mRNA, and increased expression of Rim and Rab3 4hrs after ethanol exposure. Dunc13 has …

Effects Of Multiple Stressors On Pseudomonas Fluorescens Over Short And Long Timescales, Parisa Burchfield

Electronic Theses and Dissertations

Stressors are ubiquitous factors in biological systems that result in deviations from an organism's optimal physiological state, potentially causing fitness decreases. Stressors can be biotic (e.g., predators, parasites, competitors) or abiotic (e.g., pH changes, temperature, environmental toxins). Persistent stress can lead to population declines unless organisms respond through mechanisms such as evolutionary adaptation. Experimental evolution with microorganisms, particularly bacteria, is a powerful method for studying these phenomena due to their short generation times, large populations, as well as the ability to control their environment, and freeze and revive populations. Bacteria-phage systems, such as Pseudomonas fluorescens SBW25 and its lytic phage …

Glycopolymeric Nanoparticles Enrich Less Immunogenic Protein Corona And Improve Tumor Delivery Compared To Pegylated Nanoparticles, Kenneth Ryan Hulugalla

Electronic Theses and Dissertations

Nanoparticles (NPs) offer significant promise as drug delivery vehicles; however, their in vivo efficacy is often hindered by the formation of a protein corona (PC), which influences key physiological responses such as blood circulation time, biodistribution, cellular uptake, and intracellular localization. Understanding NP-PC interactions is crucial for optimizing NP design for biomedical applications. Traditional approaches have utilized hydrophilic polymer coatings like polyethylene glycol (PEG) to resist protein adsorption, but glycopolymer-coated nanoparticles have emerged as superior alternatives due to their biocompatibility and ability to reduce the adsorption of highly immunogenic proteins. In this study, we synthesized and characterized glycopolymer-based poly[2(diisopropylamino)ethyl methacrylate-b-poly(methacrylamidoglucopyranose) …

Weight Discrimination And The Negative Cultural Value Of Fat: The Relationship To Well-Being Across Higher Weight Individuals Of Different Nations, Ana Clara Vieira Zaidan

Electronic Theses and Dissertations

Discrimination against individuals with higher body weights is prevalent in and outside of the US (see Pearl et al., 2021), yet research on this topic is limited when considering non-US perspectives. Cross-cultural studies had not yet explored the impact of cultural norms around weight. In the domain of anti-fat attitudes, cross-cultural research had explored variations in the negative cultural value of fatness (NCF) and its impacts across countries (Crandall et al., 2001). Incorporating this perspective, Study 1 examined how perceived weight discrimination (PWD) and NCF uniquely predict various well-being outcomes across two different countries among individuals who identified as overweight. …
