Whole-Genome Sequences Reveal Zygotic Composition In Chimeric Twins, Christopher J Yoon, Obi L Griffith, Malachi Griffith, Et Al.

2020-Current year OA Pubs

While most dizygotic twins have a dichorionic placenta, rare cases of dizygotic twins with a monochorionic placenta have been reported. The monochorionic placenta in dizygotic twins allows in utero exchange of embryonic cells, resulting in chimerism in the twins. In practice, this chimerism is incidentally identified in mixed ABO blood types or in the presence of cells with a discordant sex chromosome. Here, we applied whole-genome sequencing to one triplet and one twin family to precisely understand their zygotic compositions, using millions of genomic variants as barcodes of zygotic origins. Peripheral blood showed asymmetrical contributions from two sister zygotes, where …

Man Up: Masculinity And Emotional Abuse Victimization, Kola Brown

Electronic Theses and Dissertations Archive

Intimate Partner Violence (IPV) is often only thought of in the context of physical violence towards women perpetrated by men. Historically, this form of violence garnered much attention due to its objective and visible nature. Unfortunately, other forms of abuse and male victims are often not recognized and result in victim blaming. One such form of abuse is psychological aggression. Studies show that men experience IPV at nearly equal rates as women, but that men experience psychological aggression, also referred to as emotional abuse, at higher rates. Additionally, Black families have the highest rates of abuse. However, due to abuse …


Sensorimotor Grounding In Novel Word Acquisition, John Michael Hollander Jul 2024

Sensorimotor Grounding In Novel Word Acquisition, John Michael Hollander

Electronic Theses and Dissertations Archive

Embodied models of language comprehension assume that words become associated with sensorimotor experiences during word learning. Novel word learning paradigms may provide insight into embodied effects, but studies in this domain have yet to account for how concepts and information known in first language (L1) might influence the sensorimotor encoding of new words and concepts. Further, research on embodiment and bilingualism suggests that second language semantic representations involve sensorimotor encoding, but because participants in these studies are already proficiently bilingual, the manner and degree to which L1 information influences newly learned word representations remain unclear. The experiments in this dissertation …

Fortifying Federated Learning: A Comprehensive Analysis And Novel Solutions For Privacy And Security Issues In Federated Learning, Sagar Pathak

Electronic Theses and Dissertations Archive

Data exhibits a natural distribution, and effective machine learning models rely on substantial datasets. However, much data remains inaccessible due to privacy and security risks in traditional centralized settings, which require data collection on a central server. Federated Learning (FL) addresses this by moving computation to the data source instead of the server. Despite this, FL faces challenges from data and model poisoning attacks due to its distributed nature. Verifying the authenticity of clients in FL is difficult. Proposed solutions include statistical analysis of client updates, hardware-based isolation, Differential Privacy (DP), and Homomorphic Encryption (HE). However, these solutions have limitations …


Lumped Basin Characterization Based On Hydrologic Connectivity, Francesco Dell'aira Jul 2024

Lumped Basin Characterization Based On Hydrologic Connectivity, Francesco Dell'aira

Electronic Theses and Dissertations Archive

Regional models for peak-flow prediction and other established methods in hydrology, including regional calibration of physically based model parameters and multi-basin training of deep-learning hydrologic models, all rely on lumped basin characterizations. On the other hand, it is known that lumped models are heavily affected by the inherent trade-off between the detail in basin representation and the complexity in hydrologic processes that can be captured. Current lumped methods consider straightforward averages of distributed basin characteristics, which may be overly simplistic in many cases. Indeed, existing lumped descriptors may easily fall short in accounting for system heterogeneity, with the risk that …

Three-Dimensional Medical Image Registration With Applications In Proton Therapy, Rui Liao

McKelvey School of Engineering Graduate Student Theses & Dissertations

Three-dimensional deformable image registration (DIR) is an important technique in medical imaging, facilitating the alignment of images acquired from different sources or at different times for clinical diagnosis and treatment planning. In clinical proton therapy dose planning, dual-energy computed tomography (DECT) has notably improved the accuracy of estimating the stopping-power ratio map, reducing proton beam range uncertainty. To address the inter-scan motion artifacts inherent in sequential DECT acquisition, we propose a novel motion-compensation scheme to incorporate a three-dimensional DIR method into the joint statistical iterative DECT reconstruction algorithm. We successfully demonstrate that inter-scan motion corrections can be integrated into the …
