Michigan Tech Publications

Sulfur hexafluoride (SF6), widely used as an insulating gas in the power industry, decomposes during long-term operation into byproducts such as H2S, SO2, SO2F2, and SOF2. Reliable detection of these compounds is essential, since their type and concentration provide diagnostic signatures of faults in gas-insulated switchgear. We employ density functional theory combined with nonequilibrium Green’s function calculations to evaluate pristine two-dimensional carbon allotropes with nonhexagonal rings, namely Graphene+, T-graphene, and Biphenylene, as potential field-effect nanosensors. To characterize the surfaces’ atomic structures, we simulated scanning tunneling microscopy images for filled states. Each surface exhibits a distinct brightness pattern that allows its …

Cd7 Regulates The Persistence Of Terminally Exhausted Cd8 T Cells During Chronic Infection, Emerald Kan, Kelli A Mccord, Victor M Alvarez, Amanda Y Xia, Jacob P Conarty, Andreas Wieland, William H Hudson

Faculty, Staff and Students Publications

CD8+ T cell exhaustion limits immune responses during cancer and chronic infection. We identify CD7 as a tissue-specific regulator of terminally exhausted CD8+ T cells during chronic infection. CD7 expression progressively increases during exhaustion, reaching its highest levels on a subset of CD101+Tim3low terminally exhausted cells that arise in the liver. Transcriptomic analysis revealed that CD7-deficient terminally exhausted cells display altered expression of co-stimulatory, translational, and effector genes, correlating with markedly reduced persistence and increased apoptotic susceptibility. Importantly, CD7 is preferentially upregulated on PD-1+CD39+ tumor-infiltrating lymphocytes (TILs) in human head and neck squamous cell carcinoma (HNSCC), suggesting CD7 may play …

Controlling stem cell differentiation is a longstanding goal in biomedical research. Here we explore how cell fate is influenced by RNA condensates, specifically P-bodies, which modulate gene expression posttranscriptionally. We profiled the transcriptomes of biomolecular condensates in diverse developmental contexts spanning multiple vertebrate species. Our analyses revealed conserved, cell type-specific sequestration of untranslated RNAs encoding cell fate regulators. P-body RNA contents do not reflect active gene expression in each cell type but are enriched for translationally repressed transcripts characteristic of the preceding developmental stage. Mechanistically, P-body contents are controlled by microRNAs and can be profoundly reshaped by perturbing AGO2 or …


Dissecting The Intrinsic And Extrinsic Regulators Of Prostate Cancer Dormancy In The Bone Microenvironment, Mostafa M. Nasr Oct 2025

Dissecting The Intrinsic And Extrinsic Regulators Of Prostate Cancer Dormancy In The Bone Microenvironment, Mostafa M. Nasr

USF Tampa Graduate Theses and Dissertations

Metastatic disease is the primary driver of cancer-related mortality. In prostate cancer (PCa), patient survival decreases dramatically once the disease spreads to distant organs, with over 80% of metastases occurring in the bone. This dissemination is often followed by a clinically silent period of tumor dormancy that can last for years, creating a critical reservoir of cells poised for lethal relapse. A significant barrier to understanding and targeting this dormant phase has been the lack of robust experimental models. This thesis first addresses this challenge by establishing a novel stress-induced model of PCa dormancy, validated across multiple murine and human …

Abstract This qualitative study examines the Family Language Policy (FLP) of second-generation Iranian American (SGIA) parents regarding the maintenance of their heritage language (HL), specifically Persian, within two U.S. contexts: Orange County, California, and Memphis, Tennessee. Based on Curdt-Christiansen and Huang’s (2020) dynamic FLP model and Bronfenbrenner’s (1979) ecological systems theory, the research examines parental language ideologies and the impact of perceived ethnolinguistic vitality of their communities on their language ideologies. Semi-structured interviews and background questionnaires with ten families (primarily mothers, with some fathers) revealed complex and hybrid language ideologies. All participants expressed emotional and identity-related attachments to Persian, viewing …


The Horror And The Passion: The Christian/Secular Paradigm In The Twentieth-Century Southern Gothic, Matthew Ryan Pike Oct 2025

The Horror And The Passion: The Christian/Secular Paradigm In The Twentieth-Century Southern Gothic, Matthew Ryan Pike

Electronic Theses and Dissertations Archive

The goal of this dissertation is to provide a foundational definition of the southern gothic literary genre. In this analysis, I argue that the core of the southern gothic is a Christian/secular paradigm and that all of the conflict within these narratives is principally grounded in this dichotomy. Not only does this framework provide the best interpretive lens to understand the genre, but it ameliorates the cloud of confusion in the critical scholarship, wherein a wide and fluid array of propositions are advanced on what essentially comprises the southern gothic. I execute this via an interdisciplinary strategy, adopting scholarship and …

Invisible Print? Reading Skill Predicts Children's Learning Of Novel Spoken Words, Taylor J. Bryant, Dawna Duff, Bethany Bell, Lisa Fitton, Suzanne M. Adlof

Faculty Publications

Research indicates that when literate children and adults hear a new word that they have never seen in print, they create an expectation for how the word may be spelled. However, studies have not yet examined the extent to which orthographic knowledge plays a role in children's spoken vocabulary learning when words are taught without print. The current study used structural equation modelling to examine the relation between children's word reading ability and their ability to learn novel words from spoken instruction. Children (N = 335; 7–9 years; 52% female; <  1% American Indian/Alaskan Native, 33% Black, 1% Multiracial, <  1% Native Hawaiian or Pacific Islander, 2% Other; 57% White; 6% did not report race; 2% Hispanic/Latino, 97% Not Hispanic/Latino; <  1% did not report ethnicity) completed norm-referenced language and reading assessments and experimental measures of spoken word learning. Word reading ability and vocabulary knowledge uniquely predicted spoken word learning with respective medium-small and medium-large effects after controlling for phonological memory, general language ability, and nonverbal cognition. Thus, orthographic skill has important effects on vocabulary learning, unaccounted for in previous research, that should be addressed in current theory and practice.
