Force-Feedback And Load Sharing Mechanisms In Cardiac Myosin Ii Ensembles Revealed By Motor-Specific Perturbations, Omayma Alazzam, Md. Amzadul Hoque Chowdhury, Heath M. Stevens

Faculty and Student Publications

Myosin II motors within ensembles exhibit emergent force-generating behavior that varies based on ensemble size and makeup. However, the mechanisms by which myosins within ensembles sense and modulate behavior due to local and systemic changes in motor behavior, and concomitantly mechanics, remains unclear. To understand how myosin kinetics alter ensemble-level force generation, we employ myosin inotropes, specifically Mavacamten (MAVA) and Omecamtiv Mecarbil (OM), to pointedly alter myosin behavior in a concentration-dependent manner. MAVA has been shown to reduce the number of active myosin heads participating in crossbridge formation and force generation, while OM is recognized for prolonging motor attachment to …

High-Throughput Optical Analysis To Inform Design Of Electrochemical Biosensors, Nathan J. Ricks, Michael A. Pence, Monica Brachi, Shelley D. Minteer

Chemistry Faculty Research & Creative Works

Electrochemical biosensors are central to wearable diagnostics, point-of-care testing, and continuous health monitoring due to their low power requirements, compatibility with miniaturized electronics, and proven clinical impact. Despite these advantages, the development of new electrochemical biosensors remains slow, constrained by limited throughput, complex electrode–biomolecule interfaces, and challenges associated with selectivity and performance in chemically complex environments. This perspective outlines how the next generation of electrochemical biosensors can be enabled by decoupling high-throughput front-end discovery and optimization from electrochemical readouts using nonelectrochemical surrogate assays. Optical, affinity, and cell-sorting platforms, including SELEX, fluorescence-activated cell sorting, and chemically coupled fluorescence assays, allow orders-of-magnitude …

Learning In Infants Using Intrinsically Motivated Goal Conditioned Reinforcement Learning, T I Darsan

Master’s Dissertations

Traditional artificial intelligence models learn by passively digesting large datasets. In contrast, human infants discover skills by actively interacting with their bodies and environments without explicit external rewards. This thesis introduces the Composer Architecture, a machine learning framework designed to mimic this autonomous, open-ended development. The Composer architecture operates in a multi-stage loop, the latent model using Contrastive Learning Through Time (CLTT) to compress high-dimensional raw data from visual, proprioceptive, and touch sensors into a low-dimensional space. To preserve data relationships and prevent topological collapse, a Softmax activation forces these latent representations to lie smoothly on a probability simplex. A …

Design And Evaluation Of A Code-Switching-Aware Multilingual Conversational Ai System Using Advanced Rag Architectures, Ashutosh Juvale

Master’s Dissertations

Conversational artificial intelligence has become the primary interface through which hundreds of millions of users in India seek information and customer support. Yet the way these users actually write and speak is fundamentally at odds with the monolingual assumptions baked into most retrieval and generation systems: they code-switch, fluidly mixing one or more of the twenty-two scheduled languages of India with English, frequently typing Indic words in the Roman script ("mera refund kab tak aayega"). Standard Retrieval-Augmented Generation (RAG) pipelines silently fail on such input — the retriever returns off-topic passages because the query and the knowledge base live in …

Being Desi At School: Exploring The Racialized School Experiences Of South Asian American Youth, Prabha Kaundinya

Dissertations

Schools in America have been central areas for racialization, and as an immigrant, racial-ethnic minority population, South Asian American (SAA) students have been subjected to a variety of racialization processes (S. J. Lee et al., 2017; Rice, 2017, 2019; Subedi, 2013). However, what is known about SAA educational experiences is often based on celebratory stereotypes that proclaim their uniform success while neglecting attention towards the diversity of their needs (including academic, social-emotional, or mental health needs; Saran, 2015; Ngo & Lee, 2007; P.

Data-Driven Electrochemistry Reveals The Impact Of Hydrophobicity On Aptamer Cross-Reactivity, Emily Carroll, Michael A. Pence, Elizabeth Winterholler, Taylor D. Sparks, Shelley D. Minteer

Chemistry Faculty Research & Creative Works

Electrochemical aptamer-based (E-AB) biosensors offer a promising platform for reagentless detection of molecular targets, yet aptamer recognition can be limited by cross-reactivity, particularly for hydrophobic analytes such as steroid hormones. To investigate how cross-reactivity influences E-AB sensor performance, we use automation and machine learning to screen a library of possible interferent molecules against a steroid-binding aptamer, with progesterone serving as a physiologically relevant test case. Here, we develop a label-free E-AB sensor for progesterone detection using a methylene blue-modified aptamer anchored with a hexanethiol linker. We then used an automated electrochemistry platform to perform reproducible and high-throughput characterization of our …
