Sponsor: Alexandra Sofroniew, Ph.D. Classics The ancient Romans brought many obelisks from Egypt to Rome, starting in 31 BCE and going as far as to move one at 500 pounds in 357 CE, but for what purpose? Having more obelisks in Rome today than Egypt, their relocation of these monuments was to demonstrate Roman power and control over Egypt. Through investigating three particular obelisks (Solare, Santa Maria Sopra Minerva, and Lateran), their methods of transportation, the political issues between 30CE and 300CE, as well as reflections from past studies-this paper examines the imperialistic values demonstrated by three Emperors: Augustus, Diocletian, and Constantius. All the obelisks preside in Rome, functioning as ornamental items, showcasing power, compared to their original use in Egypt as religious objects. However, one reason for the existence of the obelisks includes establishing the power of ancient Egyptian pharaohs, repurposing them for a similar message. Study of the obelisks demonstrates a narrative of Egyptomania and authoritarianism in Rome, along with the slight change in function of a repeating, monumental form. A form that still represents the power of empire today. Generalization of Gain in Sonomyography- based Virtual Prosthetic Control

About Paper:
Sonomyography, which utilizes real-time ultrasound imaging to monitor muscle deformation, represents a novel paradigm for prosthetic control. Earlier work from our lab demonstrated the feasibility of an ultrasound-based platform to control a virtual prosthetic arm. This study investigated whether motor learning in such a platform generalizes across varying levels of hand closure using proportional position control. Fifteen participants performed power grasps at five closure levels (26.67%, 38.33%, 50%, 61.67%, and 73.33%) across three phases: Baseline, Learning, and Generalization. Baseline trials involved grasps at every closure level where half of them had visual feedback, and others had no visual feedback. During the Learning phase, participants practiced only the 50% target level with a -20% gain, which requires increased muscle contraction to achieve the target. Generalization trials involved practicing all the target levels without visual feedback. Preliminary results demonstrated that participants maintained this adjusted gain across all other closure levels during the Generalization phase despite the absence of visual feedback compared to Baseline. These findings suggest that motor adaptation acquired at a single target level effectively generalizes across the prosthetic's functional range, supporting the viability of simplified training protocols for ultrasound-based prosthetic control.
