Impact Of Fear Cost And Time Lag On The Dynamics Of An Ecological System Of Two Competing Predators And One Prey, Arkan Nawzad Mustafa

Baghdad Science Journal

The aim of this paper is to discover the impact of the fear of predators in prey and time lag corresponding to the gestation period on the dynamics of a food web model including two competing predator species and one prey species. Existence, non-negativity and boundedness of the model solutions are examined. An attractive region for the model is found. The permanence of the model, under certain conditions is proved. The criteria for the existence of all biologically feasible equilibrium points of the proposed model are determined. Locally asymptotically stability as well as globally stability of the model equilibrium points …

The Dynamic Of A Three Species Food Chain Model Under The Influence Of Fear And Wind, Kaherah Ibrahim Hadib, Hiba Abdullah Ibrahim

Baghdad Science Journal

This work suggests a system of ordinary differential equations (ODEs) containing a three-species food chain model incorporating wind and fear effects. The properties of the solution, like positivity and bound-ness, were investigated. All equilibrium points (biologically feasible) have been obtained, and the local stability of these equilibriums has been carried out. The global stability outcomes on the equilibrium points under specific restrictions have been established. Also, the persistence restrictions have been investigated. By utilizing Sotomayor’s theorem, the local bifurcation of the suggested model has been inspected. Furthermore, numerical analysis was carried out to ensure the theoretical results obtained by utilizing …

Renewal Of The Mind: Forgiveness Through The Lens Of Christian Faith And Neuroscience, Khelen Walsh

University Honors Theses

Within Christian theology, forgiveness is a foundational concept that is often understood as a divine command, a spiritual practice, and a path toward reconciliation and personal growth. Recent neuroscientific research further supports this viewpoint, providing data that shows forgiveness engages neural systems responsible for emotional regulation, empathy, moral reasoning, and perspective-taking. Through neuroplasticity, repeated acts of forgiveness reshape the brain, strengthen connections between prefrontal and limbic regions, reduce amygdala reactivity, and enhance emotional stability and cognitive flexibility. Although forgiveness offers many benefits, modern culture frequently distorts its meaning, framing it as a sign of weakness, gullibility, or a form of …

Multidomain Therapy For Alzheimer's Disease: A Scoping Review Of Cognitive Decline Trials, Jared C Roach, Cyrus A Raji, Et Al.

2020-Current year OA Pubs

BACKGROUND: Alzheimer’s disease (AD) leading to cognitive decline and dementia results from the interplay of multiple interacting dysfunctional biological systems. These systems can be categorized by domain, such as inflammation, cardiovascular health, proteostasis, or metabolism. Specific causes of AD differ between individuals, but each individual is likely to have causes stemming from multiple domains. Personalized multidomain therapy has been proposed as a standard of care for AD. OBJECTIVES: We sought to enumerate and describe prospective randomized controlled trials (RCTs) for multidomain interventions for AD, and to extract their inclusion criteria, trial design parameters (length, number of participants), and outcome measures. …

Osmosis Magazine

Have you ever wondered: Are we alone in the universe? Well, scientists hope to answer the age-old question and they believe that Mars could hold the answer. The red planet has been identified as a potential home to life beyond Earth, and this article aims to explore what makes Mars such a strong candidate. Understanding the conditions on extraterrestrial objects is key to determining if our existence is a unique phenomenon or if we are the product of a recurring event that happens throughout the universe.

A Tragic Love Story Neanderthal-Human Interbreeding, Parth Patel

Osmosis Magazine

Humans moved northward when it became too hot and arid. Before that, we spent a few hundred thousand years evolving to the conditions of Africa (Hajdinjak et al., 2018). Our bones, genes, and skills were all honed to ensure survival in a particular climate, so when that climate began to change, the evolutionary traits that developed through years of mutations suddenly became deficient. It forced us to move in droves to Western Eurasia, where we found some comfort in the cooler weather (Slimak et al., 2024). We also found another species of human: the Neanderthal.

Does Free Food Lead To Less Food? Dependency Theory & The Ambiguous Effects Of Food Aid, Stevi Dugas

Osmosis Magazine

Dependency Theory, in the context of food aid, holds that food aid and subsequent increases in food supply disincentivize local agricultural production, resulting in local dependence on food aid for survival. But, is this actually the case? This article first explains the economic theory behind Dependency Theory, then examines why this theory may not connect to reality and some strategies for remedying the flaws of modern non-emergency food aid to ensure effective humanitarian aid.

Mushrooms And Mind Control, Connor Beasley

Osmosis Magazine

In a humid forest climbs a lone carpenter ant. At midday, it sinks its mandibles into a leaf’s vein and is locked in place. A few days later, a thin stalk of mycelium erupts from its head, dusting the forest floor in spores to infect a new victim. The ant has been infected by an unseen puppeteer known as Ophiocordyceps unilateralis sensu lato, more commonly called cordyceps or the “zombie‑ant fungus” (de Bekker et al., 2021). When we think of mind control, visions of mad scientists and maniacal villains tend to dance through our heads; the true culprits, however, are …

Red Flags Are My Favorite Color: The Psychology Of Falling For The 'Bad Boys', Erlinda Sali

Osmosis Magazine

The “bad boy” has been a recurring figure in popular culture for years. He’s the leather-jacketed brooding rebel, the dangerous lover, the tortured antihero that we have learned to romanticize. This archetype blends “juvenile masculinities (aggression, rebellion, hypersexuality)” with appealing qualities like “charisma, ruggedness, and sensitivity,” creating a moral ambiguity that captivates audiences (Gopaldas and Molander, 2019). This contradictory mix keeps him popular across movies, songs, and advertisements. But with this archetype being ‘a walking red flag,’ why are we still so bewitched by the bad boy, and should we be?

Trouble-Making Teens: Can They Control Their Impulses?, Natasha Troike

Osmosis Magazine

Teenagers can be moody, irritable, and defiant; they may snap at their parents and make risky decisions that they regret. Decisions such as having unprotected sex or taking harmful, illegal substances can be drastically life-changing. Are these risky decisions acts of purposeful defiance, or is there more to it? Are teens truly in charge of their impulses, or are they victims of their developmental biology?

Synthetic Biology: Could You Donate Yourself A New Kidney?, Charlie Lanning

Osmosis Magazine

Currently in the United States, there are over 100,000 Americans stuck on the national transplant waiting list for lifesaving surgery. Eighty-six percent of them need kidney transplants (Organ Donation Statistics, 2025). However, only 27,000 kidney transplants take place every year. This shortage, along with other factors such as lack of public awareness, donor health complications, and financial disincentives, results in around 4,000 deaths every year (Soltani-Nia, 2024). While organizations such as the Organ Procurement and Transplantation Network and the National Kidney Registry have helped increase the number of transplants through public advocacy and the voucher program, emerging technologies such as …

Racial Capitalism And Whitelash: Trumpism And The Politics Of Oppression Redux–A New Normal Or Just New Perfume In An Old Bottle?, Bhoomi K. Thakore, J. Scott Carter, Cameron Lippard, David G. Embrick

Fast Capitalism

There is no question that Donald Trump’s actions in his second presidential term have many people bewildered, shocked, and frightened. What was deemed “not normal” in his first term in office has quickly become the “new normal.” In this paper, we argue that part of the explanation for the rise, and repeated rise, of Trumpism lies in Donald Trump’s ability to fuel and maintain a whitelash against the social progress of the 20th and early 21st century. Not only has Trumpism picked up on the “reverse racism” sentiments that have sprouted as a result of racial, gender, and social progress, …

Genetic Ancestry Strongly Impacts Mapt (17q21.31) Haplotype Frequencies Of South American Populations, Miguel A. Alfonso-Sánchez, José E. Dipierri, Ibone Espinosa, Luis Gómez-Pérez, José A. Peña

Human Biology Open Access Pre-Prints

Genetic and archaeological studies indicate that the American continent has undergone multiple waves of human migration, shaping a complex population genetic structure comprising three major ethnic groups—Native American, European, and African—unevenly distributed across the continent. In this study, we examined MAPT (17q21.31) haplotype and sub-haplotype frequencies by analyzing two SNP markers (rs10514879 and rs199451) in three South American groups from distinct countries: Waorani (Ecuadorian Amazon), Jujuy (Northwestern Argentina), and Afro-Colombian (Northwestern Colombia). To broaden the scope, we also genotyped four short tandem repeats (STRs) within the 17q21.31 chromosomal region and compiled H2 haplotype and sub-haplotype frequency data for 97 worldwide …

Mechanisms Of Correlated Neuronal Activity In The Globus Pallidus, Hamza Albawaliz

Electronic Theses and Dissertations

This thesis investigates the mechanisms of correlated neuronal activity in the globus pallidus externus (GPe), a key structure in the basal ganglia. Neuronal activity in the GPe is reportedly decorrelated in healthy subjects but can become highly correlated in Parkinson’s disease. However, high-density neuronal recordings in the GPe of healthy rats reveal a surprising degree of correlated activity. This raises the question of whether intrinsic properties or network connectivity alone can account for such patterns. To explore this, a computational model was developed in which GPe neurons are represented as coupled phase oscillators influenced by experimentally derived phase-response curves and …

Development Of A Non-Faradaic Impedimetric Biosensor Based On Reduced Graphene Oxide For The Detection Of Brain-Derived Neurotrophic Factor (Bdnf), Mariana N. Martins

Electronic Theses and Dissertations

Neurological disorders affect millions of people worldwide. In the case of Alzheimer’s disease (AD), the rising number of cases significantly increases global healthcare costs. Therefore, early detection of biomarkers at the onset of the disease is essential for early diagnosis. This study presents an electrochemical biosensor designed for the detection of Brain-Derived Neurotrophic Factor (BDNF) in human plasma, incorporating reduced graphene oxide (rGO) to enhance signal sensitivity. Dielectrophoresis (DEP) was employed to deposit rGO flakes on the electrode surface, improving conductivity and sensor performance. Electrochemical impedance spectroscopy (EIS) was used to monitor changes in impedance associated with BDNF binding events, …

Frameworks For Repatriation: Moving Beyond Nagpra, Ashley Joplin

Electronic Theses and Dissertations

Museums and similar federally funded educational institutions have been collecting human remains since the Enlightenment era in the 1800s. Since then, these institutions have developed various collections practices that have encouraged the collection of human remains. Often unethical in nature, these collections have harmed historically marginalized communities, such as Indigenous and African American communities. While the ethics of collecting have been under scrutiny for decades, it was not until 1990 under the Native American Graves Protection and Repatriation Act (NAGPRA) that mainstream attention was drawn to the ethics of collections practices.

This thesis explores these collections practices and the repatriation …

Guide For Selecting Experimental Models To Study Dietary Fat Absorption, Andromeda M. Nauli, Ann Phan, Karen Mai, Kathleen Tran, Surya M. Nauli

Pharmacy Faculty Articles and Research

Dietary fat absorption is a complex, multi-step process involving digestion, enterocyte uptake, intracellular trafficking, re-esterification, and transport via lipoproteins into circulation. Because dietary fat absorption plays a central role in lipid homeostasis, metabolic syndrome, and fat malabsorption disorders, its study has a broad biomedical significance. However, experimental investigation of this process is technically challenging due to the short lifespan of enterocytes, the dual lymphatic and portal transport routes, and the need to trace the metabolic fate of absorbed lipids. This review summarizes and critically evaluates the major experimental systems used to study dietary fat absorption, highlighting their respective strengths, limitations, …

From Vulnerability To Robustness: A Survey Of Patch Attacks And Defenses In Computer Vision, Xinyun Liu, Ronghua Xu

Michigan Tech Publications

Adversarial patch attacks have emerged as a powerful and practical threat to machine learning models in vision-based tasks. Unlike traditional perturbation-based adversarial attacks, which often require imperceptible changes to the entire input, patch attacks introduce localized and visible modifications that can consistently mislead deep neural networks across varying conditions. Their physical realizability makes them particularly concerning for real-world security-critical applications. In response, a growing body of research has proposed diverse defense strategies, including input preprocessing, robust model training, detection-based approaches, and certified defense mechanisms. In this paper, we provide a comprehensive review of patch-based adversarial attacks and corresponding defense techniques. …

Insect Apocalypse? Population Patterns Of Aquatic Macroinvertebrates Across North America, Analiese Kate Bauder

Honors Thesis

There is a common idea that there is an “insect apocalypse”, that insect populations are on a drastic decline. To test this hypothesis we took data collected by the National Ecological Observatory Network (NEON) from 2015 to 2023 and analyzed it to create a time series model depicting the population of aquatic macroinvertebrates at 34 sites across North America (Appendix 1). NEON is an NSF funded, continental-scale observation facility designed to collect long-term open-access ecological data to better understand the complexities of Earth's ecosystems and how they are changing. From this model, we defined the slope of the change in …

Linking A Seasonal Freshwater Prey Subsidy To The Body Condition Of An Estuarine Consumer In A Subtropical Coastal River, Jordan A. Massie, Ryan J. Rezek, W. Ryan James, Rolando O. Santos, Natasha M. Viadero, Ross E. Boucek, Jennifer S. Rehage

Marine Science

Movements of fishes among habitats often correspond to shifting resource availability and can occur in response to fluctuating freshwater inflows in coastal systems. Seasonal availability of prey can provide resources that increase fitness, yet hydrologic variability can influence the movements of both consumers and prey. Shifts in the timing/magnitude of prey availability driven by climate and water management may lead to a resource mismatch, carrying consequences for growth, survival, and reproduction. Here, we examined how seasonal/interannual variation in prey biomass (sunfishes, Lepomis spp.) affects the body condition of Common Snook (Centropomus undecimalis) in Everglades National Park. Further, we investigated how …
