The Mechanism Of Sperm (Pro)Nuclear Migration In Plants And Animals, Yilin Zhang, Tomokazu Kawashima

Plant and Soil Sciences Faculty Publications

Gamete nuclear migration is a critical process during fertilization in flowering plants, yet its molecular mechanisms remain poorly understood. Recent studies have highlighted the essential role of cytoskeletal elements, particularly F-actin, in directing sperm nuclear migration, contrasting with the microtubule-driven migration in animals. We summarize the process of sperm nuclear migration in plants and the involvement of Class XI myosin XI-G in Arabidopsis, along with the ROP8-SCAR2 pathway’s ARP2/3-independent mechanism for F-actin nucleation. We also provide a comparative overview of examples from sea urchins, C. elegans, mice and yeast contrasting these mechanisms with those in plants. Finally, we …

Molecules In Cool Stars: The A²Π - X²Σ⁺ And The B²Σ⁺ And The B²Σ⁺ - X²Σ⁺ Band Systems Of Cacl, Léo Lavy, Peter F. Bernath

Chemistry & Biochemistry Faculty Publications

Cool red giant stars exhibit absorption bands of calcium monochloride (CaCl) in the optical region. In this work, the bands of CaCl corresponding to the A²Π − X²Σ⁺ transition with v′ ≤ 4 and v″ ≤ 4, and B²Σ⁺ − X²Σ⁺ transition with v′≤ 2 and v″ ≤ 2 are rotationally analyzed with PGOPHER, a multipurpose program for simulating and fitting molecular spectra. All bands were analyzed using high-resolution absorption spectra collected at the National Solar Observatory in 1985, calibrated with atomic lines from a high-resolution emission spectrum obtained …

Higher-Derivative Quantum Field Theory And Its Implications For Hawking Radiation And Nonlocality, Gordon Kanan

Physics Dissertations - Archive

One of the fundamental equations of quantum field theory is the Klein-Gordon equation which can be constructed using irreducible representations of the Poincar ́e group and describes the dynamics of spin-0 matter. The higher derivative Klein- Gordon equations are also constructed using irreducible representations of the Poincar ́e group and are, thus, invariant under operations of this group. These higher derivative Klein-Gordon equations can be placed into two series depending on the power of the derivative, one for odd powers of the derivative and one for even powers, whose solu- tions yield timelike and spacelike fields. Applying these higher derivative …

Internalized Racism: A Theoretical Model, William Glen Fisher

Theses and Dissertations--Sociology

Internalized racism exists, we can observe and measure the effect it has on people. It manifests from both the psychological and sociological factors that form a person’s racial self-image. As Campón and Carter (2015) state: “less attention to date has been given to … how racial minority groups appropriate (i.e., take in) racial beliefs.” (p.498). In this dissertation, I explore how internalized racism forms. Further, I propose a new theoretical model integrating two concepts, the racialized self and racialized experiences. Racism is found at different levels, within the self through the racialized self, it highlights how People of Color view …

Welcome To The Fruit Farm: How Queer Farmers Are Shaping The Agroecology Of The Future, Alessandra Del Brocco

Theses and Dissertations--Sociology

The question of sustainability has many different facets, but one of the most urgent issues is that of sustainable agriculture. Decades of agricultural policy demanded farmers go big or get out, more colloquially known as the government directive of the 20^th century to farm “fencerow to fencerow”. In the 21^st century, we now face a near-critical consolidation of farmland and decline in the overall number of farmers. If sustainability calls for a resilient, diversified agrisystem, how can we change direction at this point in the trajectory?

In this study, I demonstrate how queer farmers make valuable contributions to …

Reconciling With The State: A Narrative Inquiry Into The Perspectives Of Reconciliation Of Wrongfully Convicted Persons In Southern Nigeria, Chinyere Erica Chisom

Department of Conflict Resolution Studies Theses and Dissertations

Wrongfully convicted persons in Nigeria experience numerous harms and losses from their wrongful convictions and face various challenges after their exoneration and release from prison. These adverse effects occur on multiple levels of the wrongfully convicted persons’ relationships and impact these relationships in profound ways. Although legal remedies exist to deal with the aftermath of wrongful convictions in Nigeria, they are grossly inadequate. Reconciliation, an innovative, holistic, and restorative measure, is required to address the impact of these devastating experiences and repair the affected relationships. Grounded in the social contract, human needs, and restorative justice theories, this study employed a …

Emerging Chromatin Regulators In Response To Heavy Metal Exposure, Wesley Saintilnord

Theses and Dissertations--Molecular and Cellular Biochemistry

Environmental exposure to heavy metals poses significant threats to human health as they are associated with various developmental and chronic pathologies such as reproductive defects and cancers. Despite their profound risks, a comprehensive understanding of their disease-causing mechanisms is lacking. Most studies point to reactive oxygen species-induced DNA damage; however, their mutagenic potential is relatively weak suggesting the involvement of alternative mechanisms. One important, yet underexplored mechanism, is their ability to rewire the epigenome via DNA methylation and histone variant incorporation, leading to aberrant gene regulatory networks.

This study investigates the epigenetic mechanisms targeted by two ubiquitous heavy metals with …

Effects Of Mindfulness Training On Prosocial Responses In Intergroup Relations: A Pilot Randomized Controlled Trial, Denise Yiran Zheng

Theses and Dissertations

Based on social identity theory and intergroup emotions theory, individuals feel for and act toward others based on their group-based social identities. Recent research shows that mindfulness can enhance prosocial responses toward others across group divides. The current research examined the effects of mindfulness training on prosocial behavior in intergroup relations where such behavior is difficult (e.g., with marginalized or devalued social groups). The study also examined potential mechanisms, namely state empathic concern and appraisal, that may explain how mindfulness increases prosocial behavior toward outgroups. This study compared the effects of a 2-week mindfulness training to a matched coping training …

Symmetry Analysis Of The Canonical Connection On Lie Groups:Co-Dimension Two Abelian Nilradical With Abelian And Non Abelian Complement, Nouf Alrubea Almutiben

Theses and Dissertations

We consider the symmetry algebra of the geodesic equations of the canonical
connection on a Lie groups. We mainly consider the solvable indecomposable four,
five and six-dimensional Lie algebras with co-dimension two abelian nilradical, that
have an abelian and not abelian complement. In this particular case, we have only
one algebra in dimension four namely; A4,12 , and three algebras in dimension five
namely; A5,33, A5,34, and A5,35 In dimension six, based on the list of Lie algebras in
Turkowski’s list, there are nineteen such algebras namely; A6,1- A6,19 that have an
abelian complement, and there are eight algebras that …

Outcomes Of Anterior Crossbite Correction On Alveolar Bone Morphology In Patients With Cleft Lip And Palate, Katherine J. Hayes

Theses and Dissertations

Objective: To determine if patients with cleft lip and/or cleft palate (CLP) with dental correction of the anterior crossbite during growth display differences in alveolar bone thickness around the maxillary central incisors compared to patients without crossbite correction.

Methods: This retrospective study evaluated post-treatment cone beam computed tomography (CBCT) images of growing patients with CLP with anterior crossbites who underwent Phase I orthodontic treatment (n=32). CBCTs were sorted by whether the crossbite was corrected (n=16) or not corrected (n=16) during Phase I. Alveolar bone thickness was measured on the buccal and palatal aspects of the central incisors at 3 mm, …

Advancing Clinical Bacterial Diagnosis: Gram-Stained Whole-Slide Image Classification With Attention-Based Deep Learning, Jack Mcmahon

Computer Science Senior Theses

We introduce a new method for the classification of Gram-stained WSIs. As a test for the diagnosis of blood infections, Gram stains are highly relevant to informing patient treatment. Rapid analysis of Gram stains has been shown to be positively associated with better clinical outcomes, indicating the need for better tools to aid in automatic Gram stain analysis. To date, this area of research has been underexplored, with previous studies relying on the manual patch-level annotation of WSIs to generate training data. This is the first application of a transformer-based model to Gram-stain WSI classification, an approach that is far …

Decisional And Intrapersonal Conflicts Regarding Treatment Choice For Breast Cancer And The Lived Experiences Encountered During Treatment., Uchennamee Vital Durulawrence

Department of Conflict Resolution Studies Theses and Dissertations

Breast cancer is a widely recognized health concern, yet the concept of 'intrapersonalconflict' within the context of breast cancer treatment is relatively underexplored. While existing research predominantly addresses the impact of a breast cancer diagnosis on everyday life, there is limited investigation into the decisional and intrapersonal conflicts that women face during the course of their treatment. This qualitative study employs transcendental phenomenological analysis to examine these conflicts and the broader experiences of women as they navigate treatment decisions, lifestyle adjustments, and relational dynamics throughout their breast cancer journey. The study participants comprised 12 women aged between 21 and 80, …
