Growth Of Cylindrical Micelles And Their Use To Prepare Porous Materials With Tailored Dimensions And Alignment, Mengxue Zhang, Xiaomeng Li, Chuanbing Tang, Morgan Stefik

Faculty Publications

Materials with cylindrical pores are optimal for electrochemical devices and filtration due to their straight paths with minimal tortuosity when aligned. Polymer templates have led to many individual cylindrical architectures however the independent tailoring of pore and wall dimensions has remained elusive. Here short cylindrical micelle templates (PEO-b-PS) with glassy cores enabled the fabrication of sample series with constant cylindrical pore diameter (∼63 nm) and tailored wall thickness (TiO₂, ∼45–100 nm). This ShortCyl series (aspect ratio 4.25) had modest alignment that was attributed to the low free-energy cost for misalignment. Though the plasticized micelles (DCM present) …

Background Skeletal muscle atrophy during cancer-induced cachexia remains a significant challenge in cancer management. Mitochondrial defects precede muscle mass and functional losses in models of cancer cachexia (CC). We hypothesized targeting Opa1-a key regulator of mitochondrial fusion-can attenuate LLC-induced CC outcomes.

Methods We utilized 1) in vivo transgenic Opa1 overexpression (OPA1 TG) in LLC-induced CC in vivo, and 2) BPG15 administration to induce Opa1 in vitro and in vivo.

Results OPA1 TG attenuated plantaris, gastrocnemius, and EDL loss with LLC in males and alleviated gastrocnemius loss infemales. OPA1 TG had greater mitochondrial respiration in plantaris and white gastrocnemius, and lowered …

Is Social Media Use A Reason For Socially Withdrawn Individuals' Mental Health Difficulties?, Angela Grundvig

Theses and Dissertations

Studies have found a link between subtypes of social withdrawal and internalizing problems throughout most of the lifespan. However, the work conducted in adolescence is much more limited including a lack of work examining factors that might mediate the association between forms of social withdrawal and internalizing problems. Social comparison may be one way in which social withdrawal predicts internalizing problems. There has been research showing that social media usage is associated with internalizing problems. The purpose of this study was to assess (a) the associations between three subtypes of social withdrawal (shyness, avoidance, and unsociability), respectively, and indices of …

A Novel High-Order Absorbing Boundary Condition For Elastic Multiple Scattering Problems, Jordan Gregory Sheppard

Theses and Dissertations

Elastic waves are waves that propagate by causing deformations in an elastic medium such as metal, rock, or rubber. The main characteristic of elastic wave motion is the coexistence of multiple types of waves at once in the medium, including compressional and shear wave components. This type of motion can be used to study the impacts of physical phenomena such as earthquakes. In this paper, we discuss our research on the time-harmonic scattering of elastic waves in a medium by multiple circular cylindrical obstacles that the wave cannot penetrate. Using the Helmholtz decomposition, we break down the vector-valued physical system …

Zea, Fokhrul Hossain, Denise Moore Danos, Jovanny Zabaleta, Augusto Ochoa, Lucio Miele, Edward Trapido, Qingzhao Yu

School of Public Health Faculty Publications

Background/Objectives: Triple negative breast cancer (TNBC) is an aggressive, molecularly heterogeneous subtype of breast cancer, accounting for approximately 10–15% of all cases. While reproductive and metabolic factors contribute to breast cancer development, growing concerns about environmental exposures, alongside biological and socio-cultural influences, underscore the need for targeted prevention strategies across diverse populations. Despite increasing evidence linking biological, socioeconomic, and environmental factors to TNBC outcomes, the molecular mechanisms underlying these relationships remain poorly understood. Micro-RNAs (miRNAs), which regulate gene expression and play critical roles in cancer development, have emerged as potential mediators between environmental exposures and TNBC progression. The goal of …

An Rna Modification Prevents Extended Codon-Anticodon Interactions From Facilitating +1 Frameshifting, Evelyn M. Kimbrough, Ha An Nguyen, Haixing Li, Jacob M. Mattingly, Nevette A. Bailey, Wei Ning, Howard Gamper, Ya-Ming Hou, Ruben L. Gonzalez, Christine M. Dunham

Department of Biochemistry and Molecular Biology Faculty Papers

RNA post-transcriptional modifications act by stabilizing the functional conformations of RNA. While their role in messenger RNA (mRNA) decoding is well established, it is less clear how transfer RNA (tRNA) modifications outside the anticodon contribute to tRNA stability and accurate protein synthesis. Absence of such modifications causes translation errors, including mRNA frameshifting. By integrating single-molecule fluorescence resonance energy transfer and cryogenic electron microscopy, we demonstrate that the N1-methylguanosine (m1G) modification at position 37 of Escherichia coli tRNAProL is necessary and sufficient for modulating the conformational energy of this tRNA on the ribosome so as to suppress +1 frameshifting otherwise induced …

Accelerating Gnn Inference On Multi-Core Systems, Binglin Ji

McKelvey School of Engineering Graduate Student Theses & Dissertations

Graph Neural Networks (GNNs) are becoming increasingly popular, with their applications expanding across diverse domains. As the scale of graph data continues to grow, including larger numbers of nodes, edges, and higher embedding dimensions, standardized libraries such as DGL and PyG have been developed to facilitate GNN computation. However, with the rapid increase in the number of processor cores and the evolution of multi-core architectures, these libraries often show poor scalability and fail to execute GNN inference efficiently on the latest multi-core systems, particularly those with upwards of a hundred cores. To address this limitation, we present FGI, a Fast …

Versatile Waveform Generation And Clocking Techniques For Rfsoc-Based Digital Designs, Michael David Jones

Theses and Dissertations

Within an ever-evolving radio-frequency (RF) environment, designers are required to adapt systems to increasingly constricted parameters. The available tools continually grow to match this need, but so does the complexity in using them. The radio-frequency system-on-chip (RFSoC) is an innovation that combines a field-programmable gate array (FPGA) with an integrated RF chain. Designing with an RFSoC allows for high-precision data transmission, sampling, and processing, but it can be difficult and time-consuming to develop specialized circuits. The open-source CASPER project aims to provide a library of abstracted block-design components to simplify the design process. An arbitrary waveform generator (AWG) is created …

Coolness, Leisure, And Power : The Development Of Mokanshan Summer Resort In Modern China, 1890–1937, Xuyan Pan

Lingnan Theses (MPhil & PhD)

The concept of "coolness" (清涼) embodied fundamentally different bodily and cultural experiences in Chinese and Western traditions. With the introduction of Western-style summer resorts by foreign missionaries in the 1890s, these divergent understandings converged and clashed in new spatial forms. This study examines Mokanshan (莫干山), located in Zhejiang province and recognized as one of the Republican era’s “Four Great Summer Retreats” (民國四大避暑地), as a paradigmatic case of transnational leisure. Initially developed by missionaries as a health-oriented retreat, a transnationally managed enclave, and a nostalgic “overseas home” for expatriates, Mokanshan reflected a hybrid model of modern leisure shaped by foreign institutions. …
