R12 Equivalent Resistance Reduction Steps, Vasiliy S. Znamenskiy, Rafael Niyazov

Open Educational Resources

We present a concise, step-by-step reduction of a symmetric resistor network to its equivalent resistance 𝑅₁₂, emphasizing visual reasoning over algebraic brute force. By redrawing the circuit to expose symmetry, we identify equipotential node pairs joined by ideal conductors; the “bottom” bridging resistor is shown to carry zero current and is removed from consideration. The remaining topology reduces by two repeated series combinations, where each left/right pair of equal resistors collapses to 2R. The final network is a three-branch parallel combination (2𝑅∥𝑅∥2𝑅), yielding the closed-form result 𝑅₁₂=𝑅/2. The procedure illustrates three transferable techniques for introductory circuit …

Challenges In Developing Physical Intuition In College General Physics Courses, Vasiliy S. Znamenskiy, Rafael Niyazov

Open Educational Resources

Many students can memorize formulas but struggle to feel what a newton, joule, or volt means; they treat formulas as plug-and-chug templates rather than descriptions of relationships among physical quantities. This presentation introduces three types of learning activities: (1) text-free (“no-text”) problems, in which carefully designed visuals replace prose to convey relationships and constraints; (2) anti-problems, which begin with a mathematical expression and ask students to imagine a physical situation it could describe; and (3) lab games that turn routine measurement into purposeful play, emphasizing estimation, scaling, and unit sense. We provide ready-made, Brightspace-compatible assessments alongside low-tech implementation options. The …

Detecting Polar Ring Galaxies Via Deep Learning, Fawad Kirmani, Anathavishnu S. Unnii, Varsha P. Kulkarni, Kyle Lackey, John R. Rose

Faculty Publications

Polar ring galaxies (PRGs) are peculiar galaxies that show a ring of stars, gas, and dust oriented roughly over the poles of the central ‘host’ galaxy (i.e. roughly orthogonal to the disc of the host galaxy). The formation models for these rings involve mergers or tidal interactions of the host galaxy with another galaxy. Although the identified PRGs look different from each other, they all have a ring that is not in the same plane as the disc of the host galaxy. Unlike in galaxies such as our Milky Way, where stars form in spiral arms, the rings exemplify an …

Household Dysfunction And Dating Violence Perpetration: The Moderating Effects Of Parental Monitoring And Closeness Among Middle School Adolescents In Southeast Texas, Sumaita Choudhury, Emily T Hébert, Timothy J Walker, Christine M Markham, Ross Shegog, Robert C Addy, Melissa F Peskin

Faculty, Staff and Student Publications

Background: Adolescent dating violence (DV) perpetration is a significant public health issue affecting millions of adolescents in the United States. Adverse childhood experiences such as household dysfunction (HD) have been exhibited to be risk factors for DV perpetration during adolescence and adulthood. Furthermore, the literature is scant regarding how positive parent-child relationships can mitigate these risk factors and decrease HD-related consequences among sixth-grade adolescents. Thus, our study examined the moderating effects of parental monitoring and closeness regarding the association between HD and DV perpetration among middle schoolers in Southeast Texas.

Faculty, Staff and Student Publications

Background: Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a functional imaging modality that can quantify tissue permeability and blood flow. Due to vasculature changes resulting from radiation therapy (RT), DCE-MRI quantitative parameters should be significantly different in regions receiving a high radiation dose compared to regions receiving a low radiation dose. This study sought to determine whether a significant difference exists in post-head-and-neck-cancer (HNC)-RT DCE-MRI quantitative parameters (Ktrans and ve) between regions of the mandible receiving a high radiation dose and regions of the mandible receiving a low radiation dose.

Methods: DCE-MRI was acquired from HNC subjects post-RT. The DCE-MRI …

Assessing Spatial Variability In Observed Infectious Disease Spread In A Prospective Time-Space Series, Chih-Chieh Wu, Chien-Hsiun Chen, Shann-Rong Wang, Sanjay Shete

Faculty, Staff and Student Publications

Most of the growing prospective analytic methods in space-time disease surveillance and intended functions of disease surveillance systems focus on earlier detection of disease outbreaks, disease clusters, or increased incidence. The spread of the virus such as SARS-CoV-2 has not been spatially and temporally uniform in an outbreak. With the identification of an infectious disease outbreak, recognizing and evaluating anomalies (excess and decline) of disease incidence spread at the time of occurrence during the course of an outbreak is a logical next step. We propose and formulate a hypergeometric probability model that investigates anomalies of infectious disease incidence spread at …

Folia Medica Indonesiana

Percutaneous Coronary Intervention (PCI) has continued to evolve since its introduction in 1977. Currently, 12% of all PCI procedures for coronary artery stenosis involve Calcified Nodules (CN). CN is defined as nodular calcification that protrudes into the lumen of the coronary artery. In this era, improving the feasibility and success of PCI is essential through the use of advanced techniques, innovative approaches, and specialized devices in coronary interventions. These techniques include Rotational Atherectomy (RA), Orbital Atherectomy (OA), and Intravascular Lithotripsy (IVL). Comparisons of RA, OA, and IVL are still being extensively studied in terms of their effectiveness and safety in …

Enhancing Mindfulness Through Communities Of Practice In Buddhist Spiritual Tourism: A Study Of Transformative Experience At Plum Village, Giang T. Phi, Trang Huong Pham Phd, Nam Vu

International Journal of Religious Tourism and Pilgrimage

Despite the growing interest in Buddhist spiritual tourism, there is a clear gap in the literature regarding the role of Communities of Practice (CoPs) in fostering transformative tourism experiences. This study investigates how CoPs at Plum Village retreats in France and Thailand facilitate transformative experiences and enhance mindfulness among participants in Buddhist spiritual tourism. Utilising qualitative methods, the study combines autoethnography—drawing on the lead researcher’s personal experience through daily reflexive journals—and participant observation of a focal ‘retreat family’ group of 15 participants at each retreat. Thematic analysis was applied to analyse the data, guided by two frameworks: Kirillova et al.’s …

From Meditation To Magic: The Spectrum Of Buddhist Tourism In Thailand, Brooke Schedneck

International Journal of Religious Tourism and Pilgrimage

Religious practices can conjure distinctive ideas and images for different groups of people, especially religious festivals, which are signs of congregations, celebrations, and contentment, usually to mark the completion of religious obligations. All major religions celebrate notable festivals to mark important events and religious obligations that bring together followers of that faith. The year 2020 will be remembered as unique in the history of all faiths. As a result of the COVID-19 crisis, governments across the world announced compulsory measures such as ‘social distancing’ and ‘lockdown’ to avoid the spread of Coronavirus. Thus, all major religions either cancelled or reduced …

Analysis Of Pilgrimage To The Evangelical Lutheran Church In Zimbabwe (Elcz) Mission Centres, Rabson Hove

International Journal of Religious Tourism and Pilgrimage

A pilgrimage is usually a sacred journey undertaken by religious adherents to holy places associated with their own traditions. As religions grow, religious pilgrimage also expands as the members of the religious traditions continue to influence each other. These holy religious centres influence religious enrichment, enhancement, strength and growth. Members get in touch with their origins and the history of the expansion of their religion as they encounter their holy sites or centres. In the case of the Evangelical Lutheran Church in Zimbabwe (ELCZ), their important holy sites are missionary centres which are commonly located in rural Zimbabwe. The majority …

Vulnerability Of Blue Carbon In Coastal Freshwater Ecosystems To Sea-Level Rise, Suvrajit Ghosh, Jonathan Obrist-Farner, Jeffery R. Stone, Marta Wojewodka-Przybyt, Ryan Smith, Mark Brenner, Jason H. Curtis, Susan R. H. Zimmerman, Alex Correa-Metrio, Paula Gabriela Echeverrio Galinda, Madeline J. Brosky, Liseth Perez

Coastal freshwater ecosystems are economically and ecologically important and provide multiple environmental services worldwide. They sequester carbon at rates ten times faster, and store five times more carbon per unit area than do mature tropical forests. Vulnerability of these carbon sinks to marine inundation, however, is expected to increase in response to global sea-level rise (GSLR). To better understand the implications of future GSLR, we investigated the geochemical and biological consequences of episodic Holocene marine incursions into Lake Izabal, a large coastal freshwater ecosystem on the Caribbean coast of Central America. About 8300 cal yr BP, marine incursion transformed Lake …

Faculty, Staff and Students Publications

Schistosomiasis is caused by parasitic flatworms (Schistosoma). The disease in humans can be caused by seven different species of Schistosoma: S. mansoni, S. japonicum, S. haematobium, S. malayensis, S. mekongi, S. guineensis and S. intercalatum, as well as by hybrids between species, including livestock schistosome species. People are infected when exposed to infested water and the parasite larvae penetrate the skin. Poor and rural communities are typically the most affected, and the general population who lives in affected areas and is exposed to contaminated water is at risk. Areas with poor access to safe water and adequate sanitation are also …

Digging Deeper With Deep Ram Networks, Andrew J. Wagner

Dissertations and Theses

While Deep Neural Networks (DNNs) have driven major breakthroughs in artificial intelligence, their internal complexity often makes their behavior hard to explain, resulting in the well-known “black box” dilemma. This thesis addresses the challenge of interpretability in DNNs and deep reinforcement learning (DRL) through two main contributions.

In Part I, we revisit and extend the use of Deep RAM Networks (DRNs) within the Arcade Learning Environment (ALE), showing that, with modern architectures and careful hyperparameter tuning, RAM-based agents can achieve performance competitive with established pixel-based baselines on Atari 2600 games, while offering additional advantages for research and analysis. We also …

All-Optical Voltage Interrogation For Probing Synaptic Plasticity In Vivo, Jacques Carolan, Michelle A Land, Xiaoyu Lu, Maxime Beau, Dimitar Kostadinov, François St-Pierre, Beverley A Clark, Michael Häusser

Faculty, Staff and Students Publications

Measuring synaptic efficacy and defining the rules for induction of synaptic plasticity at identified connections in the mammalian brain is essential for understanding how synapses contribute to learning and memory. This requires new approaches to selectively evoke presynaptic activity and measure postsynaptic responses with high spatiotemporal resolution and high sensitivity over long periods in vivo. Here we develop an all-optical approach to probe synaptic plasticity at identified cerebellar synapses in awake, behaving mice. We developed and applied JEDI-2Psub, a genetically encoded voltage indicator with increased sensitivity around resting membrane potentials, to record subthreshold and suprathreshold activity in Purkinje cell (PC) …

Background: Outdoor air pollution is a suspected risk factor for childhood cancer, and there is some evidence that greenness may reduce cancer risk. We examined relationships between prenatal exposure to ambient fine particle air pollution [particulate matter < 2.5 µg/m3 (PM2.5)], greenness, and childhood cancer risk in Minnesota.

Methods: Cases included individuals born in the state of Minnesota and reported to the Minnesota Cancer Reporting System between 2000 and 2014 (n = 1272, ages 0-14 years at diagnosis) and birth year-matched cancer-free controls (n = 5245). We used Network Common Data Form to estimate monthly PM2.5 exposure and the normalized difference vegetation index for census tract-level greenness. We estimated ORs and …

Peña-Rodriguez V. Colorado And The Racial Animus Exception To The No-Impeachment Rule: Extending And Exception To Suspect Classes That Experience Pervasive Bias In The Jury System, Taariq Lewis

Florida Law Review

During an inquiry into the validity of a verdict, Federal Rule of Evidence 606(b) prohibits jurors from testifying about statements made or incidents that occurred during jury deliberations, including jurors' subjective mental processes used in reaching the verdict. This rule is often called the "no-impeachment" rule. The no-impeachment rule promotes the finality of verdicts, facilitates free and vibrant discussion by jurors without fear their verdict will be questioned, and ensures that jurors are not harassed by litigants seeking to challenge their verdict. However, in a landmark U.S. Supreme Court case, Pena-Rodriguez v. Colorado, the Court held that a defendant's …

"Cold Words, Heartless And Miserable": Tolkien's Approach To Supernatural Horror, Dylan L. Henderson

Journal of Tolkien Research

For the most part, scholars of supernatural horror do not consider J. R. R. Tolkien a contributor to that genre, a conclusion supported by many Tolkien specialists. And yet, horror plays a major role in many of Tolkien’s works, specifically The Lord of the Rings. Indeed, “Fog on the Barrow-downs” is basically a tale of supernatural horror that Tolkien has incorporated into his epic. This article examines that chapter in that context, comparing it to a similar short story by E. F. Benson, and this approach not only highlights the links between Tolkien and contemporaneous supernatural horror—the shares themes …
