Motor Subsystem For A Tensegrity-Based Robotic Exoskeleton, Presley Sacavitch, Israel Villegas

College of Engineering Summer Undergraduate Research Program

Tensegrity structures are composed of stiff rods and elastic cables suspended in a flexible tension network. In particular, the biotensegrity model proposes that all biological systems exhibit tensegrity-like characteristics across multiple scales, ranging from the cellular level to the musculoskeletal system of tendons, ligaments, and fascia, to the human body as a whole. Compared to the traditional biomechanical models used in exoskeleton design, it can be a more accurate representation of how motion emerges from natural forms, but further work is needed to fully understand the heterarchical nature of human anatomy. This project will focus on developing a powered electrical …

Thou Shalt Not Castrate: The Conflict Between Louisiana’S Surgical Castration Law And The Principles Of Medical Ethics, Morgan Ambrosecchia

Dickinson Law Review (2017-Present)

In 2024, Louisiana became the first state to permit courtordered surgical castration for sex offenders who have been convicted of certain sex crimes against children. Under the law, an offender who refuses to submit to the procedure will face an additional three to five years in prison without the possibility of parole, probation, or suspension of sentence. The court’s order is contingent on confirmation by a court-appointed expert that the offender is an “appropriate candidate for surgery.” However, the statutory language is vague and does not clearly define who can serve as an expert nor does it define the scope …

Exploring Undergraduate Early Childhood Education Students' Conceptualizations Of Stem In Early Learning Contexts, Melany Spiehs

Educational Leadership Theses, Dissertations, and Student Creative Activity

Early childhood is widely recognized as a critical stage for STEM (science, technology, engineering, and mathematics) learning, yet many teachers feel underprepared to support children’s foundational knowledge and skills. This study examines how undergraduate students in early childhood education conceptualize STEM within early learning environments through an analysis of their coursework and field experiences. The investigation explores both students’ articulated beliefs about STEM (espoused theories) and how they enacted STEM teaching and learning in practice (theories-in-use). Data were drawn from course artifacts including journals, reflections, learning stories, lesson plans, and field observation notes. While much of the existing literature emphasizes …

Let's Bee Pragmatic: The Economic Case For Neonicotinoid Regulation In Conservative States, Annie Rosenstein

William & Mary Environmental Law and Policy Review

The importance of bees in our ecosystem and to our food system in the United States cannot be overstated. In fact, 35% of global crop production depends on bees and other pollinating insects. Pollinators not only influence the production of many foods that we hold dear and rely on, such as apples, chocolate, potatoes, and coffee, but also influence the quality of these products.

Currently, the most insidious threat against bees in the United States is neonicotinoid pesticides (neonics). While neonics are effective at killing the target populations of beetles, aphids, and flies, they are equally effective at killing pollinators, …

Look What You Made Me Do, Russell M. Gold

Washington and Lee Law Review

We have understood for centuries that crime is both the product of social forces and individual choice. We know now that crime is affected by economic deprivation, addiction, trauma, and mental health issues. But American criminal legal processes hide this reality by coercing defendants into expressing a profoundly simple narrative: crime is solely individual choice to do wrong. This coerced narrative finds defendants during a plea colloquy standing up in court saying that they are pleading guilty because they are guilty and for no other reason. A defendant who goes off-script to tell the judge that they have been repeatedly …

Double Dosing: How Brand-Name Pharmaceutical Manufacturers Manipulate Patent Rules To Extend Market Exclusivity, Elizabeth Hertzberg

Washington and Lee Law Review

A robust patent system is important for spurring innovation, but it is not without risk. Because a patent owner has exclusivity over the patented subject matter for a specific term, there is incentive to extend that monopoly however possible. Identical subject matter is unpatentable, but obvious variants of an existing patent may be allowed if the applicant agrees to the same expiration date for both patents. This agreement is called a terminal disclaimer. While patents tied together with terminal disclaimers may not necessarily lead to unjust patent term extensions, an army of terminal disclaimers directed at one invention presents a …

Proteomic Approaches To Investigate Pp2a-B55 Substrates And Cellular Function, Brennan C. Mcewan

Dartmouth College Ph.D Dissertations

Cell division is controlled in large part by reversible protein phosphorylation. The phosphorylation state of proteins during mitosis and other phases of the cell cycle represents a careful balance of activity between kinases and opposing phosphatases. The phosphoprotein phosphatase (PPP) family is responsible for the majority of serine and threonine dephosphorylation. Members of the PPP family are composed of a catalytic subunit paired with a regulatory subunit that targets them towards specific substrates.

The most abundant PPP, PPP2A, paired with its regulatory B55 subunit, is thought to be the phosphatase responsible for the dephosphorylation of substrates during mitotic exit. Despite …

To account for solvent effects and electrostatic screening, calculations incorporated an implicit solvent environment via the polarizable continuum model (PCM). The dataset includes optimized geometric coordinates, harmonic vibrational frequencies, and simulated infrared (IR) spectra for each cetyl trimethyl ammonium-anion pair. Additional computational details, including input parameters, …

Student Perceptions Of Standards-Based Grading In High School Biology, Scott Bohlman

Master's Theses & Capstone Projects

Standards-based grading (SBG) redefines the reporting of student achievement by focusing on proficiency in explicitly defined learning standards rather than the accumulation of points. Although SBG has the potential to improve student learning, variation in implementation can create student confusion and hinder effectiveness. This inquiry-based research project investigated student perceptions of SBG in high school biology classrooms at Cedar Falls High School in Iowa to determine whether the system helps students gain the necessary skills and accurately measures their academic ability. The researcher utilized a mixed-methods approach, collecting quantitative data through surveys of 23 high school biology students and qualitative …

Examining Choices Of Sarcastic Responses In Dialogue With Virtual Interlocutors, Samantha Langley

Theses and Dissertations

We report the results from three experiments examining people’s preferences for using sarcasm in conversation as a function of: 1. whether their interlocutor uses sarcasm during the conversation; 2. Their knowledge about whether the interlocutor has used sarcasm in a previous conversation; 3. The presence of prosodical and visual cues for interlocutors’ sarcasm. In each experiment, participants took part in two conversations, and we manipulated whether the interlocutors were sincere or sarcastic and whether they remained the same or changed from one conversation to the next. Experiment one used written conversations and experiment two and three used pre-recorded video clips …

Rethinking Equality In Mathematics Education With Category Theory, Kelly Paton

The Mathematics Enthusiast

To provide an alternative to the flattening operations of equality, which are prevalent not only in mathematics but also in our everyday world, I introduce the relational structures of category theory and their more nuanced notions of equivalence. Instead of defaulting to a binary assignation of equal or not-equal, equivalence posits that contextual relationships are integral to how we conceive of ‘same’ and ‘different’. I draw upon the ideas of philosophers who work against the erasure of diversity and offer ways to uphold difference while searching for commonalities. As I trace the sociopolitical implications of embracing an ontological framework built …

Positive Depression Screen Among Pregnant Women Attending Antenatal Clinic At Aga Khan University Hospital, Michael Maina Muriithi

Master of Medicine in Obstetrics and Gynecology

Introduction: One in seven women experience peripartum depression, a common disorder that can occur during pregnancy or in the postpartum phase. Women are particularly vulnerable to depressive symptoms during pregnancy and the immediate postpartum period due to physiological changes during pregnancy as well as other sociocultural stressors. Peripartum depression is associated with significant maternal and perinatal adverse outcomes, including self-neglect, substance use, preterm birth, low birth weight and poor neurocognitive development, in offspring. There is a need to understand the prevalence and factors associated with depressive symptoms during pregnancy to improve maternal and neonatal outcomes. To our knowledge, this …

Oral And Maxillofacial Pathology Case Of The Month, John E. Kacher Dds

The Journal of the Michigan Dental Association

This case concerns a 39-year-old female patient presenting with an asymptomatic radiolucency and spiking root resorption in the right posterior mandible (tooth #30). The patient delayed treatment for three years due to the COVID-19 pandemic and fear of surgery. Upon return, the lesion had greatly expanded in size (approximately 22-by-17 mm), with increased root resorption. Surgery involved extraction of the tooth and thorough curettage of the lesion. Microscopic examination showed cellular tumor composed of plump spindle cells and interspersed psammoma body calcifications. The final diagnosis was aggressive ossifying fibroma, psammomatoid variant. Treatment typically involves complete local excision and curettage …

Mitochondrial Dysfunction And Lipid Dysregulation In Yeast Lacking Phosphatidylserine, Alaumy Joshi, Zakery N Baker, Rachel A Stanfield, Dimitris T Kalafatis, David J Pagliarini, Vishal M Gohil

2020-Current year OA Pubs

Mitochondrial membrane phospholipids impact mitochondrial structure and function by influencing the assembly and activity of membrane proteins. Although the specific roles of the three most abundant mitochondrial phospholipids, phosphatidylcholine (PC), phosphatidylethanolamine (PE), and cardiolipin (CL), have been extensively studied, the precise function of less abundant phosphatidylserine (PS) is not yet determined. Here, we used genetic and nutritional manipulation to engineer a set of yeast mutants, including a mutant completely devoid of PS, to assess its role in mitochondrial bioenergetics and lipid homeostasis. To circumvent the confounding effect of downstream PS products, PE and PC, we exogenously supplied ethanolamine that allows …

Succinate Dehydrogenase B (Sdhb) Overexpression With Enzymatic Dysfunction Defines A Distinct Subtype Of Undifferentiated Pleomorphic Sarcoma, Miguel Esperança-Martins, Brian A Van Tine, Alliny C S Bastos, Et Al.

2020-Current year OA Pubs

UNLABELLED: Undifferentiated pleomorphic sarcoma (UPS) remains one of the most clinically aggressive and poorly characterized soft-tissue sarcoma subtypes. To uncover distinctive molecular traits for UPS, a multiomics analysis of UPS compared with leiomyosarcoma (LMS) and liposarcoma (LPS) was performed. Transcriptomic profiling revealed that UPS exhibits overexpression of genes encoding succinate dehydrogenase (SDH) subunits, particularly SDHB, SDHC, and SDHD, distinguishing it from LMS and dedifferentiated LPS. This finding was validated using The Cancer Genome Atlas Sarcoma dataset. High SDHB expression in UPS was significantly associated with shorter overall survival, shorter recurrence-free survival, and shorter overall survival from the date of first …
