Personalizing Heat Information For Adults Over 65, Bruce C. Pollock Jr

Electronic Theses & Dissertations (2024 - present)

In the lead-up to extreme heat events, federal agencies, such as the National Weather Service (NWS), issue products and messages that advise people as to expected impacts, duration, and protective actions of the hazard. Within social media graphics, words such as “elderly” are used but are not defined by age. This can complicate personalization of risk to a hazard, such as extreme heat. I conducted focus groups across the United States and found that the term "elderly” was not understood among the general population. Additionally, I found that definitions of aging were tied to concepts such as mobility, resource access, …

Modeling Feature And Instance Interactions In Longitudinal Data For Improved Performance, Khandker Sadia Rahman

Electronic Theses & Dissertations (2024 - present)

Tabular data has been a core representation format in machine learning, widely used in high-stakes domains such as healthcare, finance, and social services. In many of these domains, data is collected longitudinally, capturing sequences of events and evolving feature values for the same entities over time. Despite its prevalence, most machine learning approaches assume mutual independence between features and independent and identically distributed (i.i.d.) instances. However, these assumptions limit effectiveness in settings where features and entities exhibit complex interdependencies. Moreover, existing approaches frequently overlook a critical dimension: the real-world impact of the decisions informed by model predictions. This thesis addresses …

Phylogenetic Analysis Of Metabolic Enzymes In Hypoxic/Anoxic Conditions In Cetaceans And Cancer, Samerna A. Masih

Electronic Theses & Dissertations (2024 - present)

Cancer cells often exhibit a Warburg-like metabolism, which includes increased fatty acid synthesis and storage that help them survive in hypoxic conditions. This shift is marked by the heightened synthesis and accumulation of fatty acids, acting as a survival mechanism in low-oxygen environments (Baumann et al., 2016). Interestingly, deep-diving whales may utilize a similar metabolic pathway to produce wax esters during their prolonged dives.

Our study focused on exploring the genetic and metabolic similarities between breast cancer cells and deep-diving whales, using computational analyses to investigate lipid metabolism genes. We looked for evolutionarily conserved variations that might reveal adaptive mechanisms …

Characterization Of Corticotropin Releasing Factor Receptor 2 In Stress-Regulating Regions Of The Mouse Brain, Jennifer J. Lafrican

Electronic Theses & Dissertations (2024 - present)

Sex differences in the morphology of the brain are thought to underlie the sex differences we see in anxiety and depression, where women are twice as likely to be diagnosed when compared to men. Stress, or a disruption to homeostasis, can exacerbate these mood disorders. Corticotropin releasing factor (CRF), and its receptors, play an important role in regulating the stress response. Binding of CRF with CRFR2 has been shown to reduce behavioral and neuroendocrine stress responses, yet whether there are sex differences in CRFR2 expressing neurons and stress-induced activation of these neurons in mice is unknown, in part due to …

Association Of Non-Communicable Diseases With Severe Covid-19 Among People Living With And Without Diagnosed Hiv/Aids In New York State, Ravi Kumar Balu

Electronic Theses & Dissertations (2024 - present)

Background: People living with diagnosed HIV (PLWDH) have a higher chance of co-infections and co-morbidities than the general population. When SARS-CoV-2 was first reported in China in December 2019 and later declared a pandemic, it was speculated that PLWDH might be more prone to SARS-CoV-2 infection and severe disease outcomes given their increased vulnerability to other respiratory infections like influenza, pneumococcal pneumonia and tuberculosis. However, several facets of COVID-19 disease in PLWDH are incompletely understood, including whether non-communicable diseases (NCDs) are strong risk factors for severe disease outcomes and death as they are in the general population.

The Role Of The Nasal Migratory Mass In Olfactory Bulb Formation And Fertility, Charisse Martin

Electronic Theses & Dissertations (2024 - present)

The olfactory migratory mass plays an essential role in the development of the olfactory bulb by facilitating the migration of the gonadotropin-releasing hormone neurons from the olfactory placode to the pre-optic hypothalamic area in the brain. In mammals, the migration of GnRH neurons is critical for establishing the hypothalamic-pituitary-gonadal axis (HPG axis), which regulates reproductive function through the production and secretion of gonadotropins. Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) instruct the gonads to function appropriately, ensuring sexual maturation and fertility. Disruptions in this migratory pathway have been linked with Kallmann syndrome, a condition characterized by low levels of GnRH, …
