Generation Of A Transgenic Vector For The Purpose Of Transforming Charcoal Rot Resistance Into Soybeans (Glycine Max), John M. Bear Jr

Electronic Theses & Dissertations

Charcoal rot, caused by Macrophomina phaseolina, is among the most devastating fungal pathogens affecting G. max, particularly in drought-susceptible regions such as the midwestern United States. Traditional agricultural practices have included crop rotation and irrigation, which have proved ineffective or economically unfeasible. Charcoal rot infects over 500 other species of plants and can overwinter as dormant sclerotia which can germinate once soybeans are re-planted and infect young plants. As a result, transgenic solutions have offered a promising alternative for the development of disease-resistant soybeans. This thesis documents the construction of a transgenic vector to express BOZO, a …

Effect Of Hearing Status On Modified Balance Error Scoring System Performance, Matthew Brancaleone, Claire Akard, Jaclyn Caccese

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

OBJECTIVE
Concussion assessments typically include evaluations of self-reported symptoms, neurocognitive function, and postural control. Specifically, postural control is often assessed using the modified Balance Error Scoring System (mBESS). Although normative mBESS data exist, they may not be appropriate for all athletes, such as those who are deaf or hard-of-hearing (D/HoH). Given the relationship between the cochlea and the vestibular system, athletes who are D/HoH may exhibit differences in postural control due to potential vestibular dysfunction. Therefore, the objective of this study was to compare mBESS performance between athletes who are D/HoH and athletes who are hearing.

Capturing The Representational Dynamics Of Face Perception In Deep Recurrent Neural Networks, Hossein Adeli, Chase W. King, Nikolaus Kriegeskorte May 2025

Capturing The Representational Dynamics Of Face Perception In Deep Recurrent Neural Networks, Hossein Adeli, Chase W. King, Nikolaus Kriegeskorte

MODVIS Workshop

We investigate the representational dynamics of recurrent convolutional neural networks (RCNNs) in order to understand the time-course of visual recognition. We explore a family of models with bottom-up and lateral connections that were optimized for face-identification and object-recognition tasks. Using representational similarity analysis (RSA), we observed that only models that were trained for face identification showed a late-emerging prominent distinction of identities as seen in the monkey face patch AM. Early model responses strongly separated the objects from the faces. These findings suggest that the dynamics of face recognition that emerges in a hierarchical recurrent neural network prioritizes category-level recognition …
