Utilizing Physics Informed Neural Networks For Disrupted Signal Dynamics, Nicholas J. Joyner

Electronic Theses and Dissertations

Physics-informed neural networks (PINNs) have been used in many applications including engineering and physical sciences. PINNs allow the incorporation of a priori understanding of a process’ structure into the modeling. We attempt to leverage the PINN structure toward the evaluation of disruptions to classical dynamical models by combining elements of ordinary differential equations into our loss function with sigmoidal gating to balance the penalties for deviations from the data with those for structural deviations. This enables the identification of the signal structure and the limits of disruption influence. As a use case, we consider stock value from 2019-2021, which expresses …

Ligand-Based Pharmacophore Modeling And Structure-Based Virtual Screening For Identifying Potential Therapeutic Agents Targeting The Sars-Cov-2 Spike Protein-Ace2 Receptor Interaction, Timoteo Delgado-Maldonado, Gilberto Vargas-Salas, Debasish Bandyopadhyay, Adriana Moreno-Rodriguez, Eyra Ortiz-Pérez, Gildardo Rivera-Sanchez

School of Integrative Biological & Chemical Sciences Faculty Publications

Coronavirus disease (COVID-19) remains a global health concern due to its high mortality and morbidity. In this study, we combined ligand-based pharmacophore modeling (LBPM) with structure-based virtual screening (SBVS) to identify novel inhibitors targeting the SARS-CoV-2 spike protein. Ligands from the MolPort database were screened via docking and molecular dynamics simulations at the receptor-binding domain (RBD). Four compounds showed promising docking scores (-8.7 to -6.4 kcal/mol) and dynamic stability (root mean square deviation < 5 Å). In vitro assays confirmed that compounds C3 (IC50 = 0.03 µM) and C4 (IC50 = 10.4 µM) effectively inhibited spike-ACE2 binding with low cytotoxicity (CC50 > 100 µM). These findings show the efficacy of the LBPM technique and highlight 1H-pyrazol-5-ol derivatives as potential building blocks for developing new antiviral agents against SARS-CoV-2.

"Obsessive Myth:" Disturbing The Grammar Of The Lyric And Epic In Theresa Hak Kyung Cha's "Dictee", Noelle (Nell) Kriegel

All Theses

The archival text Dictée by Theresa Hak Kyung Cha spans many genres, making it a highly hybrid text. Cha uses personal letters, official government documents, images, prose, dictation exercises, translations, and poetry to create a composite identity of women neglected through history. Dictée’s hybrid form allows it to experiment with the lyric and epic traditions, challenging their forms to adequately reflect the lived experience of oppressed women. Dictée’s hybridity is but one aspect of its interrogation of literary form and language; the text also plays with grammar, specifically pronouns, to depict a genealogy of female voices as they relate to …

Ableism In Higher Education: Platicas Framing Faculty Perception Of Student Accommodations And A Call To Action, Stephanie P. Rivas

Electronic Theses, Projects, and Dissertations

Academic ableism and traditional educational practices hinder the success of disabled students (Dolmage, 2017). As a student with disabilities, I have witnessed gradual improvements in the perception of disabilities in education. However, academic ableism persists in today’s higher education institutions, which can be disheartening for students like me, an unapologetically disabled person. This study employs framing theory, a communication theory that explains how people interpret and organize information (Goffman, 1947). These frames influence how accommodations are perceived, shaping attributes and connections between behaviors and potential causes (Tewksbury & Scheufele, 2019). Using platicas, a kind of cultural method of open conversational …
