(Si16-04) Some Fixed Point Theorems On Chatterjea Type Contractions, Irom Shashikanta Singh, Y. Mahendra Singh

Applications and Applied Mathematics: An International Journal (AAM)

This paper establishes the existence of fixed points related to strict Chatterjee contractive mappings by relaxing the compactness of the underlying spaces and the continuity of the mapping involved, using altering distance functions and comparison functions in the general setting of metric spaces. Several non-trivial and illustrative examples are provided to demonstrate, support, and validate the obtained theoretical results. In addition, a theorem that can characterize the completeness of metric spaces through the existence of fixed points is rigorously proven and discussed. Furthermore, a theorem on strict Chatterjea-type modulus contractive mappings without continuity assumptions and with relaxed compactness conditions is …

(Si16-06) Equations Of Geodesics In Two-Dimensional Finsler Manifold With A Special Cubic (Α, Β)-Metric, Sejal Prajapati, Brijesh Kumar Tripathi, V. K. Chaubey

Applications and Applied Mathematics: An International Journal (AAM)

Geodesics represent the shortest path between two points in curved spacetime and are vital in the study of Finsler manifolds. Matsumoto and Park first derived the geodesic equation as a secondorder differential equation in a two-dimensional Finsler manifold with Randers, Kropina, and Matsumoto metrics. Building on this foundation, our paper presents the geodesic differential equation for a two-dimensional Finsler manifold using a special cubic power metric. In this two-dimensional setting, this work also looks at certain well-known geometric curves and analyzes their variants as solutions to the geodesic differential equation. Additionally, this work examines the geometric applications of the geodesic’s …

(Si16-07) Computing The Kirchhoff Index And The Wiener Index Of Spiro Para Hexagonal Cylinder Chain, Md Selim Reja, Sk. Md. Abu Nayeem

Applications and Applied Mathematics: An International Journal (AAM)

In graph theory, the Kirchhoff index serves as a metric to evaluate the complexity of a graph. It is determined by adding up the resistance distances between every pair of vertices in the graph. In a network created from the given graph by substituting each edge by a unit resistor, the resistance distance between a pair of specified vertices is equivalent to the electrical resistance between them in the constructed network. Basically, it measures the convenience with which data or flow can move between various locations in a network that the graph represents. In terms of graph matrices, the Kirchhoff …

In this article, a one predator-one prey model incorporating Richards’ type growth in prey population, Hassell-Varley type functional response and Michaelis-Menten type prey harvesting is proposed and analyzed. Richards’ type growth with fear factor is incorporated in the proposed model to generalize the reduction effect of predator-induced fear on the rate of growth of the prey population. Positivity and boundedness of the system’s solutions are first established to ensure biological feasibility of the model. Existence and stability conditions of various types of equilibrium points associated with the model such as trivial equilibrium, axial (predator–free) equilibrium and coexistence equilibrium are obtained …

Circuit And Synaptic Mechanisms Of Methamphetamine Induced Cognitive Deficits During Abstinence: Roles Of The Perirhinal-Prefrontal Pathway And The Nucleus Reuniens, Sarah Goldsmith

MUSC Theses and Dissertations

Cognitive deficits during abstinence are a hallmark of methamphetamine (meth) use and indicative of negative treatment outcomes. In rats, both long access meth self-administration and meth binge produce recognition memory deficits due to drug-induced plasticity within the perirhinal cortex (PRH). PRH projections are numerous and include the medial prefrontal cortex (mPFC) and the Nucleus Reuniens (NRe). In the first study, the role of the PRH-mPFC reciprocal circuit in novel object recognition memory was investigated by infusing an rgAAV encoding GFP-tagged Cre recombinase into the PRH or the mPFC. Following surgery, rats explored objects. During exploration, PRH neurons receiving input from …

The Impact Of Human Myoblasts On Macrophage Polarization In A Coculture Model, Elisabeth Ann Stodola

Biomedical Engineering

Peripheral Artery Disease (PAD) is characterized by the buildup of atherosclerotic plaque in the lower extremities that occludes blood flow, and affects over 200 million people worldwide. Without effective treatment, PAD can lead to claudication, ischemia, ulcers, and gangrene. PAD causes more amputations in the United States than any other condition, and for severe cases that require revascularization, procedures benefit fewer than 50% of patients. This demonstrates a clear need for alternative therapies. Potential therapies for PAD target expansion of collateral blood vessels around the area of occlusion – a process called arteriogenesis to compensate for loss of blood flow …

When A Man Is Stressed, It Replicates In The House”: Kenyan Women’S Perspectives On The Influence Of Male Partners On Perinatal Mental Health Among Women Affected By Hiv, Hellen Moraa, Joan Mutahi, Winnie Atieno, Grace John-Stewart, John Kinuthia, Manasi Kumar, Mary Marwa, Ben Odhiambo, Felix Abuna, Jillian Pintye

Institute for Human Development, East Africa

Mental health conditions are a major public health concern in the African region, where women experience a high prevalence of maternal mental health conditions and limited access to adequate care. This issue is particularly severe among women living with HIV (WLHIV), who face a heightened risk of depression and anxiety. Despite the well-documented association between male partner-related factors and maternal/child health outcomes, their impact on perinatal mental health from the perspective of women is not well understood. We conducted semi-structured interviews and focus group discussions with women affected by HIV. Thematic analysis revealed common sources of mental distress they experienced. …

Cultural beliefs significantly influence the experiences of disabled children and their families, with stigma perceived and felt differently across cultural groups. Participants were interviewed about their family and cultural beliefs, perceptions of disability, and experiences with school collaborations and social stigma. Thematic analysis revealed that South Asian families with children with ESN faced …

The Fourth Amendment's Right To Be Secure, Thomas K. Clancy

William & Mary Bill of Rights Journal

Beginning with a 1998 article and through the editions of my treatise, I have argued that the right to be “secure” must be properly understood. The right to be secure is the powerful ability to exclude the government, and it protects against physical and technological intrusions. As will be discussed, my interpretation has had some influence among courts and scholars. Several academics have taken time to discuss it, and it has been noticed in the Supreme Court. This Essay seeks to dispel some of those characterizations and clarify the meaning of the right to be secure.

The Amendment in its …

A Synthetic Marketplace: Rethinking First Amendment Theory In The Age Of Ai-Generated Video, Jared Schroeder, Heesoo Jang

The Business, Entrepreneurship & Tax Law Review

First Amendment theory is unprepared for the synthetic-media era. AI-generated videos, which fundamentally portray events and actions that never happened, are changing the ways people construct reality in fundamental ways. These believable videos raise substantial concerns about foundational assumptions of First Amendment theory, particularly the marketplace of ideas. Synthetic videos challenge citizens to discern truth from falsity in new ways. These challenges are multiplied by the nature of video, which scholars have noted audiences find uniquely believable. This article examines First Amendment theory, as well as the nature of video, ultimately contending that the rationales the Supreme Court has traditionally …

At The Crossroads: Sports Betting In Missouri And Proposals For Regulations, Jimin Shumate

The Business, Entrepreneurship & Tax Law Review

Sports betting is a rapidly growing industry nationwide, and Missouri became the 39th state to legalize the practice. Although states hope to reap the benefits of a regulated sports gambling market, the activity carries significant mental, physical, and socioeconomic risks due to its inherently addictive nature. The hyper-accessibility of modern platforms, particularly those enabling unlimited micro betting, magnifies longstanding concerns in a new digital context. Compounding these risks, the absence of federal standards for minimum wagering ages and the aggressive marketing strategies employed by sportsbooks draw in young adults. This article proposes a coordinated federal and state regulatory framework that …

Beyond The Prompt: The Social Costs Of Generative Artificial Intelligence, J. Scott Christianson, Josh Rickard

The Business, Entrepreneurship & Tax Law Review

The rapid commercialization of generative artificial intelligence has produced extraordinary value for technology companies while systematically externalizing costs onto society. This Article provides a review of these externalities across three domains: environmental, human health, and digital infrastructure. The environmental burden includes massive energy and water consumption alongside ecologically destructive mining for rare earth elements and accelerating electronic waste. The human toll encompasses a documented pattern of AI-induced mental health crises, including suicide and self-harm linked to anthropomorphic chatbot design, raising novel questions of product liability in cases like Garcia v. Character.AI. The digital commons face degradation through industrialized data scraping …

Stress Management And Resilience Among Students Enrolled In The Entry Level Master Of Science In Nursing (Elmsn) Program, Pius Omolewa, Adekemi Adedipe, Nassrine Noureddine, Destiny Roberts

All Faculty Scholarship

Objectives: The aim of the study was to evaluate the effect of mindfulness exercises on stress management and resilience among ELMSN students. Methods: The study was a quasi-experimental design that used a paired samples t-test to compare pre-test and post-test of students’ scores on both GAD-7 anxiety screening tool and short version of Grit-scale. Statistical tests were conducted with significance set at p < 0.05 (two-sided). All analyses were performed using IBM SPSS Statistics, version 31.0 to compare pre-/post-test scores, determine differences, and statistical significance of interventions among the cohort. And a priori power analysis was conducted to determine the required sample size for a paired samples t-test. With an alpha level of 0.05 and a medium effect size (Cohen’s d = 0.50), a total sample size of N = 34 was determined to be sufficient to achieve a power of 0.80. Results: A convenience sample of 40 students (35 females and 5 males) participated in the study. Students had more anxiety before mindfulness exercises (M = 7.00, SD = 5.5) compared to after the mindfulness exercises (M = 6.2, SD = 3.4), t(39) = 1.41, p = 0.17. The effect size was small, d = 0.22. However, the difference in the students’ anxiety levels after the mindfulness exercises was not statistically significant, with a p-value of 0.17. On the resilience, students were less resilient before mindfulness exercises (M = 3.58, SD …

Varicella Zoster Encephalitis In An Immunocompetent Middle-Aged Female With Benign Neurological Presentation, Kopalle Bhanu Sriram, Swathi B.S, Bernice Roberts

Digital Journal of Clinical Medicine

Varicella Zoster Virus (VZV) is a neurotropic human herpesvirus that typically presents as herpes zoster following reactivation of latent infection. Central nervous system involvement such as encephalitis is uncommon and is more frequently described in immunocompromised individuals. Increasing use of polymerase chain reaction (PCR)-based diagnostics has enabled improved recognition of VZV-related neurological disease in immunocompetent hosts.

We describe a middle-aged immunocompetent female who presented with a 15-day history of persistent headache associated with vomiting and low-grade fever. Examination revealed vesicular eruptions in the T8–T9 dermatomes, while neurological examination and neuroimaging were normal. Cerebrospinal fluid (CSF) analysis demonstrated lymphocytic pleocytosis, elevated …

A Diffuse Interface Model And Fully Decoupled, Energy-Stable Scheme For The Two-Phase Ferrofluid Flows In Porous Media, Guo Dong Zhang, Shuai Zhou, Yunqing Huang, Xiaoming He, Xiaofeng Yang

Mathematics and Statistics Faculty Research & Creative Works

We propose a new diffuse interface model for two-phase porous media ferrofluid flows, employing the phase-field method and establishing an associated energy law. This thermodynamically consistent multi-physics model integrates the Cahn-Hilliard equations, Darcy equations, the magnetostatic equation, and magnetization equations. To efficiently solve the system by addressing its inherent nonlinearities, coupling, and saddle-point structure, we incorporate several advanced techniques, including the SAV-ZEC method to handle nonlinearities and couplings, a reformulated approach to decouple the linear coupling of the magnetic potential and magnetization, and the pressure projection method to decouple velocity and pressure. This results in a numerical scheme that is …

The 'Golden Hour': A Geospatial Analysis Of Travel Time To Public Emergency Departments In Kenya, Tushara Surapaneni, Nancy Kinyua, Benjamin Wachira

Emergency Medicine, East Africa

Introduction In Kenya and many other low- and middle-income countries, prehospital care systems are underdeveloped or entirely non-existent, leaving emergency departments (EDs) as the primary point of care for medical emergencies. The aim of this cross-sectional observational study was to use a geographic information system (GIS) to comprehensively analyse access to public EDs in Kenya within 1-hour and 2-hour travel times.

Methods Using open-source GIS software, population, land cover, elevation and road network data were analysed to create maps of 1-hour and 2-hour travel time catchment areas around public EDs in Kenya. Travel time analysis was calculated using AccessMod with …

Alfred Russel Wallace Notes 39. What About Wallace's 'Agnosticism'...?, Charles H. Smith

Faculty/Staff Personal Papers

Alfred Russel Wallace (1823−1913) seems to have distinguished his earlier years of agnosticism from his later period as a spiritualist, but a closer look at the situation suggests he actually remained an agnostic all the way through to the end of his life. The confusion is occasioned by a lack of terminology that can be applied to his position, which most closely resembles a Spinozian manner of thinking.

With advancements of modern medicine, more people are living longer lives. However, cognitive decline has become a greater issue faced by a growing number of people. The amount of People Living With Dementia (PLWD) has increased substantially, almost 10 million a year, and as such need different living conditions than what used to serve them (Alzheimer’s Disease International, n.d.). The common solution in the western world is to care for elders in specific sites for them like nursing homes or to hire a live-in nurse to care for them. These services are costly, highly specialized, and tailored to care for …

An Seir Model On Time Scales With Discrete Applications To Tuberculosis, E. Akın, G. Yeni, D. Konur, S. R. Işık, M. R. Işık

Mathematics and Statistics Faculty Research & Creative Works

In this paper, we propose a novel dynamical model on time scales consisting of new parameters to investigate the transmission dynamics of tuberculosis (TB), one of the deadliest infectious diseases worldwide, characterized by a long latency stage. The dynamical TB model, governed by the Susceptible–Exposed–Infected–Recovered (SEIR) framework within a unified form, yields a continuous model with a non-saturated incidence rate on the real numbers and discrete models with saturated incidence rates when different time domains are chosen. We analyze the stability of the equilibrium points of both the continuous TB model on the set of real numbers and the discrete …
