Baseline Factors And Their Association With Refractive Error And Control In A Pediatric Randomized Clinical Trial Of Overminus Therapy For Intermittent Exotropia, Julianne L. Robinson

USF Tampa Graduate Theses and Dissertations

Intermittent exotropia (IXT) is a condition resulting in an eye deviation away from normal alignment, potentially treatable with overminus lenses. These induce accommodation of the eye, combatting the eye drifting outward. Overminus lenses may help treat IXT but also potentially worsen refractive error. Analyses aimed to find associations of baseline factors as they relate to IXT control outcomes, as well as the risk of worsening spherical equivalent refractive error (SER). One hundred ninety-six participants aged 3 to <11 treated with overminus lenses for 12 months were analyzed to explore associations between age, sex, race, ethnicity, strabismus severity, accommodative convergence/accommodation ratio (AC/A), and baseline SER with outcomes of change in SER and change in control. Analyses included outcomes for both SER and control as continuous and binary outcomes, and a secondary combined outcome. More myopic baseline refractive error and older age were associated with a worsening in SER after 12 months, -0.08 diopters (D) worsening SER per 1 year age increase (95% CI -0.13 to -0.03), and -0.30 D worsening SER per additional 1 D of myopic refractive error (95% CI -0.39 to -0.21). A larger AC/A ratio was associated with better distance control (0.11 points improvement per D of AC/A, 95% CI 0.03 to 0.19). The combined SER and control outcome showed the same factors (age, baseline refractive error, and AC/A ratio) were significantly associated with improving outcomes. Overminus lens therapy may be beneficial for some patients, but further study is needed to explore the results of these exploratory analyses.

Emergent Magnetism And Magneto-Transport Phenomena In Helimagnet-Based Heterostructures For Spin-Based Device Applications, Nivarthana Waruni Yapa Abeyrathna Yapa Mudiyanselage

USF Tampa Graduate Theses and Dissertations

The study of magnetoresistance (MR) phenomena in magnetic materials has been pivotal for advancing magnetic sensors and spintronic devices. Helimagnets, characterized by a non-collinear arrangement of magnetic moments that form a helical or spiral configuration, present an intriguing avenue for MR-based device applications. Theoretical predictions suggest that the MR magnitude in the helimagnetic (HM) regime can exceed that in the ferromagnetic (FM) regime by over an order of magnitude. However, in metallic helimagnets like manganese phosphide (MnP), the MR in the HM phase remains modest (< 10%), limiting its applicability in MR devices. This dissertation investigates the emergent magnetism and magneto-transport phenomena in nanostructured MnP helimagnets and their interfaces with ferromagnets (Fe) and ferrimagnets (Fe3O4), aiming to enhance device performance.

In the first part of the dissertation, we present a novel approach to achieve …
