On Two-Generator Subgroups Of Mapping Torus Groups, Naomi Andrew, Edgar Bering Iv, Ilya Kapovich, Stefano Vidussi, Peter Shalen

Faculty Research, Scholarly, and Creative Activity

We prove that if (Formula presented.) is the mapping torus group of an injective endomorphism (Formula presented.) of a free group (Formula presented.) (of possibly infinite rank), then every two-generator subgroup (Formula presented.) of (Formula presented.) is either free or a (finitary) sub-mapping torus. As an application we show that if (Formula presented.) is a fully irreducible atoroidal automorphism, then every two-generator subgroup of (Formula presented.) is either free or has finite index in (Formula presented.).

Mitigation Behaviors Of Homeowners And Renters In The Wildland Urban Interface, Aishwarya Borate, Omar Pérez Figueroa, Douglas Houston, Christopher Ihinegbu, Ariane Jong-Levinger, Jochen E. Schubert, Brett F. Sanders

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Residential development within the wildland-urban interface (WUI) has greatly expanded in the United States since the 1990s, amplifying wildfire risk by placing people and structures in greater proximity to flammable vegetation. Household wildfire mitigation actions can vary substantially by cost, knowledge required, and perceived effectiveness, but few studies have examined them separately and how their adoption varies by housing tenure in the context of wildfires. To address this gap, we surveyed residents living in WUI areas within Southern California near recent burn scars in the Santa Ana and San Bernardino Mountain ranges. Drawing on the Protection Motivation Theory and the …

Under Pressure: Performance Loads And Recovery In Ncaa Division I Women’S Soccer During Fixture Congestion, Jade X. Dawson, Fabiano T. Amorim

Health, Exercise, and Sports Sciences ETDs

Soccer places high physiological demands on athletes, and match congestion—playing more than two games per week—is a growing concern at the NCAA Division I level. Limited recovery time between matches can impair performance and increase injury risk, prompting widespread use of recovery strategies. However, research on their effectiveness remains inconclusive, and most existing studies focus on male athletes, leaving a gap in evidence specific to female players. This review and observational study aim to evaluate non-nutritional recovery strategies in NCAA Division I women’s soccer and examine how recovery duration influences performance.

Match load data were collected from eleven female athletes …

Ehealth Technologies In Transitional Care Interventions For Stroke Survivors And Caregivers: A Scoping Review, Orachorn Lumprom, Charuwan Kritpracha, Cansel Kocakabak, Jos M. Latour

School of Nursing and Midwifery

The high rate of stroke disability necessitates extensive care during transitions between hospitals and homes. While many transitional care interventions have emerged, no explicit evidence illustrates the details of those combining or integrating eHealth. The aim of this scoping review was to comprehensively map the literature on eHealth technologies within transitional care interventions for stroke survivors and their caregivers. Studies were included if they focused on transitional care interventions that combined or integrated eHealth technologies for adult and elderly survivors of post-hyperacute stroke, as well as for caregivers aged 18 years and older. A systematic search was conducted from inception …

Modulation Of Redox-Sensitive Cardiac Ion Channels, Rawan S. Orfali, Al Hassan Gamal El-Din, Varnika Karthik, Elisanjer Lamis, Vanna Xiao, Alena Ramanishka, Abdullah Alwatban, Osama Alkhamees, Ali Alaseem, Young-Woo Nam, Miao Zhang

Pharmacy Faculty Articles and Research

Redox regulation is crucial for the cardiac action potential, coordinating the sodium-driven depolarization, calcium-mediated plateau formation, and potassium-dependent repolarization processes required for proper heart function. Under physiological conditions, low-level reactive oxygen species (ROS), generated by mitochondria and membrane oxidases, adjust ion channel function and support excitation–contraction coupling. However, when ROS accumulate, they modify a variety of important channel proteins in cardiomyocytes, which commonly results in reducing potassium currents, enhancing sodium and calcium influx, and enhancing intracellular calcium release. These redox-driven alterations disrupt the cardiac rhythm, promote after-depolarizations, impair contractile force, and accelerate the development of heart diseases. Experimental models demonstrate …

Current Continuity In Auroral System Science, Jules Van Irsel

Dartmouth College Ph.D Dissertations

The Earth relies on the Sun's energy, but at times this energy can be overwhelming; the Sun expels plasma which, were it not for our humble magnetic field, would erode our atmosphere (Mars, c. 4 Ga). The protective interaction Earth has with the solar wind results in spectacular auroral displays---one such auroral form is discussed in this thesis: quiet discrete auroral arcs.

Such arcs have long been studied; they are abundant, have usable symmetries, and they can predict magnetic substorms that wreak havoc in our magnetosphere. The auroral emissions, albeit beautiful, are however only the visible end of a self-consistent …

Despite the artificial technological context, participants experience genuine encounters that balance digital …

Mediating The Exquisite: Aesthetic Affordances Of The Network Arts, Seth Adams

Journal of Network Music and Arts

This paper argues that the Network Arts afford uniquely nuanced aesthetic interactions among humans and between humans and machines. After defining these moments under a new concept I call exquisite musicking, I investigate how distributed networks of human and nonhuman actors create experiences that challenge or complicate traditional notions of agency, ensemble, aesthetics, and synchrony. Using Actor-Network Theory as a lens of inquiry, I explore the exquisite affordances of network-based musicking, discussing how pitch, timbre, and texture are co-created in networked performances. I also examine how exquisite musicking could serve as a fruitful concept in music education, particularly in pedagogical …

The Devil’S In The Details: Opposition To Demonology In Early Modern Europe, Abigail Pickard

The Purdue Historian

Common assumptions that believers of witchcraft in the early modern period were uneducated fanatics overgeneralize the complex interplay of early modern science and theology. The study of demons, known as demonology, was considered a science. It was a respected field that was studied and debated. Theologians scrutinized, defended, and revised demonological theories. Thinkers turned over foundational concepts and split hairs over the fine details of theology. Since educated scholars were considered authorities on demonology, they repeatedly wrote, talked, and theorized about the topic in a similar fashion to other ideologies of the early modern era. Due to this, authors of …

Ideological Independence In The Third World: Legacies In Resistance And Anti-Colonial Aid In 20th Century Africa, Evelyn Ohs

The Purdue Historian

The Cold War, despite its central focus on the U.S.–Soviet rivalry, marked a period of rapid geopolitical and ideological transformation in the Third World. These changes were best exemplified by radical revolutionary movements that swept across the African continent. For revolutionary leaders, the spread of anti-colonial, socialist, and nationalist ideas represented more than rhetorical sentiments; they had their own visions of sovereignty and self-determination. Although rooted in shared Third-Worldist, Pan-Africanist, and non-aligned principles, these leaders and their ideas reflected significant variation in approaches to diplomacy, the use of force, and the scope of Pan-African solidarity, which profoundly shaped the nature …

Tumult, Terror, And Tripping: The Roles Of Psychedelics And Radical Politics In The Counterculture, Daniel J. Melbert

The Purdue Historian

From the immense political upheaval of the Civil Rights Movement and anti-war protests to the advent of the hippie counterculture and its psychedelic aesthetic, the 1960s is commonly conceptualized as a significantly transformative period in American history, socially, culturally, and politically. While this is certainly an accurate observation, the political and cultural shifts that occurred within this period are typically approached as separate, if not disparate, segments within the development of the period. The counterculture is often approached solely within the confines of its art, aesthetics, bohemian lifestyle, and perhaps most ubiquitously, the use of psychedelic drugs. As a result, …

Xyy: Why? Science For The People And The Xyy Controversy, Fern Rice

The Purdue Historian

The mid-20th century saw a boom of scientific discoveries in genetics as people sought to understand the American political landscape through genomes. The desire to understand criminality through genetics rose as counterculture surged. The genetic defect known as “XYY syndrome” became connected to criminality through biased medical studies and sensationalized criminal cases worldwide. When the National Institute of Mental Health began to fund studies attempting to prove a link between XYY syndrome and criminality, organizations concerned with scientific justice took notice. The leftist organization Science for the People campaigned against an XYY study in Boston, deeming it unethical and biologically …

Recent Advances In Modeling Of Electrical Discharges In Planetary Atmospheres, Seth Gerow, Jared Nelson, Jeremy Riousset, Josef Dufek, Joshua Mendez

Discovery Day - Daytona Beach

Our work focuses on plasma discharges produced in various planetary atmospheres. This process can create luminescent emissions at low currents and low temperatures: glow and corona discharges. The parallel plate geometry used in Townsend’s theory lets us develop a theoretical formalism, with explicit solutions for the critical voltage effectively reproducing experimental Paschen curves. Here, we present a generalization of the classic parallel plate configurations to concentric spherical and coaxial cylindrical geometries in Earth, Mars, Titan, and Venus atmospheres. We show that glow coronæ form more easily in Mars’s low-pressure, CO2-rich atmosphere than in Earth’s high-pressure, N2-rich atmosphere. Additionally, we present …

Astrobiological Gigantism: An Examination Of Deep-Sea Gigantism In Extraterrestrial Oceans, Connor White, Katherine Campbell, Hannah Lyons, Alexander Evanow, Dr. Sean Crouse

Discovery Day - Daytona Beach

Astrobiological gigantism refers to the potential emergence of disproportionately large organisms in extraterrestrial aquatic environments, particularly within the subsurface oceans of water-based moons and exoplanets. This paper examines the evolutionary, ecological, and environmental factors that could drive the development of gigantism beyond Earth, drawing parallels with deep-sea gigantism observed in Earth's oceans. By integrating astrobiology, planetary science, and evolutionary biology, this research aims to establish a framework for understanding how life may evolve under extreme conditions and what implications such discoveries may have for the search for extraterrestrial life. Further, this study evaluates specific celestial bodies—Europa and Enceladus—that may provide …

Hybrid Hierarchical Swarm Robotics For Planetary Exploration, Eeman Abid

Discovery Day - Daytona Beach

This project proposes a novel approach to planetary exploration utilizing a hybrid hierarchical swarm robotic system inspired by social insect colonies. The project will develop a centralized 'queen' robot that provides high-level direction to a team of semi-autonomous 'worker' robots, each capable of making local decisions while following the queen's strategic guidance. This structure aims to enhance adaptability and efficiency by balancing centralized coordination with distributed execution. The approach aligns with NASA's CADRE mission, which uses coordinated rovers to map the lunar surface. By combining simulation in ROS2/Gazebo with physical testing on lunar regolith simulant, this research will evaluate how …

Painting With Ai: Enhancing Creativity And Understanding In The Arts Classroom, Erica Blum

International Journal of Emerging and Disruptive Innovation in Education : VISIONARIUM

In the context of contemporary art and design education, the rapid advancement of generative artificial intelligence has introduced profound shifts in both creative practice and pedagogical responsibility. Art and design professors now encounter students who approach AIdriven tools with a mixture of skepticism and curiosity, often perceiving such technologies as antithetical to authentic artistic development or as expedient alternatives to disciplined practice. This article articulates an instructional approach that leverages Adobe Photoshop’s generative capabilities—specifically neural filters, generative fill, and the manipulation of alpha channels— to position artificial intelligence as a collaborative, rather than substitutive, element within digital art-making. The 2025 …
