Single treatments with psychedelics produce rapid, long-lasting antidepressant effects. Psychedelics may also exert anxiolytic effects and be useful in treating more complex psychiatric conditions, such as PTSD. However, less is known about the impact of these agents on PTSD-related symptoms. Thus, we aimed to determine whether a single administration of psilocybin could reverse PTSD-like sequelae induced by stress-enhanced fear learning in rats. Sprague-Dawley rats were placed in Context A (circular, white conditioning box) and exposed to several uncontrollable footshocks (Stress) or no footshocks (No Stress). The next day, the rats were placed in Context B (square conditioning box with clear …

Most individuals consume caffeine on a daily basis. Research has shown that caffeine stimulates the release of glucocorticoids and catecholamines and can enhance cognition. Caffeine also amplifies stress-induced increases in arousal and aggravates PTSD-like symptoms. Thus, we examined the impact of caffeine on memory for a stressful experience and intrusive memories related to that experience. Undergraduate students ingested caffeine or a placebo. Thirty minutes later, they were exposed to the Trier Social Stress Test (TSST; stress condition) or friendly-TSST (f-TSST; control condition), both of which were designed to enable participant memory for the experiences to be quantified. In each condition, …

Cultivating Home: Nepali Migrants And Gardening As Everyday Rhetoric, Menuka Gurung Lama

Frontera Retórica Symposium

Rhetorical knowledge is often discussed through formal institutions and textual traditions, leaving everyday community practices underexamined. This paper engages the theme “Rhetoric from the Margins” by examining how Nepali migrants’ gardening practices in Hooksett, New Hampshire produce knowledge outside dominant academic and institutional frameworks. I ask: How do Nepali migrants use gardening as a way of making meaning, sustaining memory, and cultivating belonging in unfamiliar environments? In what ways does gardening function as a rhetorical and epistemic practice through which migrants carry and transform land-based knowledge across borders? Rather than treating gardening simply as leisure or subsistence activity, I examine …

Halo: High Autonomous Low-Swap Operations, Sloan Hatter, Blake Gisclair

Mathematics and System Engineering Student Publications

Orbital object detection is a vital aspect of space operations, particularly for identifying satellite components. Convolutional Neural Networks (CNNs) are typically used for such operations by running onboard models directly on satellite systems. However, a new neural network architecture, known as Vision Transformers (ViTs), have shown greater effectiveness due to their ability to capture global context. One main issue of deploying systems with such capabilities is resource allocation. One solution is to run models on a Low-SWaP system; however, this results in inefficient performance. To enable efficient ViT operations on Low-SWaP systems, the model must be scaled down through quantization, …
