Qualitative Analysis Of Solutions To A General Class Of Nonlinear Difference Equations With Applications, Osama Moaaz, Mohamed F. Abouelenein, Mona Anis

Mathematical Modelling and Numerical Simulation with Applications

This work examines the qualitative behavior of a general class of difference equations. We establish criteria guaranteeing the stability, periodicity, and boundedness of the solutions of the equation under consideration. In addition, we identify its invariant intervals. The theoretical results are subsequently applied to various special cases, among them the May--Host model. Numerical simulations are presented to demonstrate the dynamics of the solutions and to validate the theoretical analysis.

Diabetes And Insulin Resistance, Causes And Treatment- A Review, Aoss Moez Abed–Alhussian Alyassery, Anas Al-Yasiry, Zainab Mahmood Al-Jammali

Muthanna Medical Journal

Background: Insulin resistance, is a hormone that is produced in the beta cells of the pancreas and works to manage the sugar balance in the body, it usually occurs when the cells in the muscles, fat and liver do not respond properly to insulin and thus cannot absorb glucose from the blood, which leads to increased work of the pancreas to increase glucose.

HOMA-IR is probable a person may be infected 10 or 15 years ago from beginning the type 2 diabetes. When it derives addressing insulin resistance, life style changes should be the importance.

Adaptation Of The Transition Readiness Assessment Questionnaire For Pediatric-Onset Multiple Sclerosis: Protocol For A User-Centered Design Approach, Claudia Gambrah-Lyles, Aaron W Abrams, Sara Loud, Hollie Schmidt, Emily Blosberg, Melissa Wright, Kelsey E Poisson, Kristen S Fisher, Kimberly A O'Neill, Akash Virupakshaiah, John W Rose

Faculty, Staff and Students Publications

Background: Pediatric-onset multiple sclerosis (POMS) is a chronic, progressive neurologic condition requiring lifelong management and coordinated transition from pediatric to adult care. Evidence-based guidelines identify transition readiness assessment as a core component of successful transition; however, most POMS clinics do not formally assess readiness, and existing tools do not address POMS-specific challenges, such as fluctuating disability, complex treatment regimens, and cognitive impairment. This gap underscores the need for a transition readiness measure tailored to POMS.

Objective: This paper aims to describe a stakeholder-engaged, implementation science-guided protocol for adapting the Transition Readiness Assessment Questionnaire (TRAQ) version 6.0 to reflect the unique …

Navigating The Cocoon: An Interpretative Phenomenological Analysis Of Mothers’ Experiences Of Seeking Diagnosis And Services For Children With Disabilities In Insular Rural American Samoa, Elizabeth Cutrer, Ocean K. Akau, Lorena Seu, Isabel Medina Hull, G. E. Kawika Allen, Ofa H. Kanuch, Cameron W. H. Hee, Melia Fonoimoana Garrett

Faculty Publications

This study examines how mothers raising children with disabilities in American Samoa experience the processes of seeking diagnosis, navigating special education, and advocating for services within an insular rural context. American Samoa, an unincorporated U.S. territory located 2600 miles from Hawaiʻi with a population under 50,000, represents a case of what we term insular rurality—a condition in which the structural disadvantages of rurality are intensified by oceanic isolation, territorial governance, and colonial history. Data were collected through three focus groups with fifteen mothers whose children hold a range of disability diagnoses, with a card sort activity at the outset of …

On The Edge Of Science?, Mark Briffa, Lynne U. Sneddon

Animal Sentience

In The Edge of Sentience, Jonathan Birch (2024) provides a thought-provoking synthesis of current perspectives on animal (and artificial) sentience. He addresses the question from conceptual, ethical, regulatory and empirical viewpoints. Here we focus on some of the scientific issues raised, including defining and operationalising the concept of sentience and the implications for policy and regulation. Despite unresolved conceptual challenges, the book makes a compelling case for the continued scientific investigation of animal sentience.

The Soil Crisis In Modern Food Systems: Rethinking Agricultural Land Use, Antonia Moure Richard

Journal of Food Law & Policy

Feeding a larger world while preserving the resource that makes agriculture possible—soil—poses a governance problem. By 2050, food systems must support 9.8 billion people even as prevailing practices continue to degrade soils that are non-renewable on human timescales. Technological fixes (e.g., vertical farming, hydroponics) may complement production, but they cannot substitute for soil at scale. The question that follows is simple: are current uses of soil compatible with the future needs of food systems? This article argues that without a shift in governance, short-run productivity gains are achieved by drawing down the soil asset, thereby undermining long-run food security and …

Production Of Organo-Mineral Fertilizing Ameliorants Based On Phosphogypsum, Central Kyzylkum Phosphorites And Biohumus, Temur A. Ospanov, Axmed M. Reymov, Rashid K. Kurbaniyazov, Jaxanger M. Bisenbaev

CHEMISTRY AND CHEMICAL ENGINEERING

Phosphogypsum, a large-scale industrial by-product generated during phosphoric acid production, poses significant environmental challenges due to its accumulation and potential ecological impact. This study investigates the utilization of phosphogypsum as a raw material for producing fertilizing ameliorants in combination with Central Kyzylkum phosphorites and biohumus. Composite mixtures were prepared and granulated using a 30% ammonium sulfate solution as a binding agent. The chemical composition, phase structure (XRD), and microstructure (SEM–EDS) of the obtained materials were analyzed. The results demonstrate the formation of calcium phosphate and sulfate phases, including CaHPO4·2H2O, β-Ca3(PO4)2, and CaSO4·2H2O, which contribute to both fast- and slow-release nutrient …

Computational Analysis Of A Single Air Bubble Rising In Quiescent Water Under Temperature Variations, Mokdad Hayawi Rahman, Muna Khalil Shehan, Emad Qasem Hussein, Farhan Lafta Rashid

Al-Farahidi Expert Systems Journal

Two-phase fluid flow is widely encountered in petroleum, chemical, nuclear, and energy applications. Computational fluid dynamics (CFD) by ANSYS Fluent 17.2 has been employed in this work to simulate the rise of a single air bubble through stagnant water at different temperatures (0 °C, 25 °C, and 50 °C). In addition, a user-defined function(UDF)was developed and implemented to incorporate phase-change behavior and temperature-dependent properties. This study investigates how the buoyancy-driven bubble dynamics will be responsive to changes in liquid viscosity, surface tension, and density. The results demonstrated that increasing the temperature of water enhances the bubble rise velocity significantly; the …

The Layered Knowledge Profile, Harendra A. Alwis Mr.

Defensive Publications Series

The Open Knowledge Format (OKF) gives the world a portable, vendor-neutral envelope for knowledge — markdown files with YAML frontmatter, cross-linked into a graph — and, by deliberate design, declines to specify how the knowledge inside that envelope should be organised, requiring only a single type field and defining the interoperability surface rather than the content model. The Layered Knowledge Profile (LKP) supplies the content model that OKF leaves open. It encodes, as machine-readable structure expressed entirely within OKF's own conventions, the asymmetric ontological dependency among the four realms of reality described by Alwis (2026), so that a body of …

Shipwrecks: A Genuine Pollution Risk, Farid Hatimy

Revue Marocaine de Droit, d'Economie et de Gestion (Moroccan Journal of Law, Economics and Management)

Marine pollution, defined as the introduction by humans of substances or energy into the marine environment causing harmful effects, is often associated with major maritime accidents. Modern vessels carrying immense cargoes and large quantities of fuel pose significant threats when reduced to shipwrecks through incidents such as breakage, grounding, sinking, or explosion. These shipwrecks represent a genuine risk of accidental—rather than operational—pollution. The author examines how such maritime disasters endanger marine ecosystems, biological resources, human health, and maritime activities including fishing and leisure, highlighting the critical need for effective prevention and intervention measures.

The Child Born Out Of Wedlock In Morocco, Mohamed Chafi

Revue Marocaine de Droit, d'Economie et de Gestion (Moroccan Journal of Law, Economics and Management)

Unlike French law, which recognises legitimate, natural, adulterine, and adoptive filiation, Moroccan law only acknowledges legitimate blood filiation. Marriage is the exclusive foundation of family ties; adoption is formally prohibited, and extramarital sexual relations as well as adultery are criminally sanctioned. A child born out of wedlock cannot be recognised by the father nor establish natural paternity, nor can the father legitimise the child through subsequent marriage. Consequently, the illegitimate child finds themselves in a situation comparable to that of adulterine children in pre-Revolutionary France, effectively devoid of any legal relationship with their biological father.

Unified Cognitive Architecture For Distributed Manifold Reasoning Systems, Donevin Frownfelter

Defensive Publications Series

Donevin Frownfelter ([email protected])

This disclosure describes a unified cognitive architecture that integrates three complementary systems—VESPER, NEPHILIM, and the Unified Agent Reasoning Model (UARM)—into a single operational framework for distributed reasoning, semantic computation, and multi‑device intelligence. The architecture introduces a manifold‑based cognitive substrate, enabling agents to perform reasoning as transformations across a non‑Euclidean semantic space rather than through traditional symbolic or statistical pipelines.

The system employs a tensor‑manifold representation for knowledge, a Majorana‑parity logic layer for reversible inference, and a distributed execution mesh that allows heterogeneous devices to participate in a shared cognitive topology. VESPER provides the laminar reasoning core, NEPHILIM …

Non-Euclidean Geometries And Fairness Constraints In Advanced Clustering, Arnab Seal

Master’s Dissertations

A fundamental challenge in modern unsupervised learning is adapting classical clustering algorithms to handle complex, real-world data constraints. Traditional models often assume data resides in a flat, Euclidean space and optimize strictly for cluster cohesion, thereby failing to capture intrinsic hierarchical structures and ignoring sociotechnical demographic biases. This thesis addresses these critical limitations by extending generalized mean-shift dynamics into two novel clustering frameworks. First, to natively accommodate data with tree-like structures (e.g., taxonomies and social networks), we propose Hyperbolic Gaussian Blurring Mean Shift (HypeGBMS). By projecting data into the Poincar´e ball model and utilizing M¨obius vector space operations, HypeGBMS successfully …

Leveraging Spatial Statistics For Domain Adaptation Of Vision Language Models In Medical Vqa, Himanshu Raj

Master’s Dissertations

Recent advances in Vision–Language Models (VLMs) have demonstrated strong performance in Medical Visual Question Answering (Medical VQA) task. Although they perform very well within their domains, these models often experience issues with their generalization ability on unknown clinical distribution data because of different imaging technologies and patient groups used in various medical facilities. Generalization problems faced by these models make their practical application in the field of VLM-based medical VQA systems rather difficult. To overcome this limitation we proposed our method named Spatial Semantics Aware Domain Adaptation (SSADA), which is an integrated framework that combines both finetuning and prompt-based in-context …

Exploring Gene Regulatory Neural Network Biocomputing Of Bacteria, Adrian Merle Ratwatte

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Artificial Intelligence (AI) has evolved from brain-inspired algorithms into a discipline that increasingly integrates with biological systems. While silicon-based platforms have advanced machine learning, they remain limited in energy efficiency and operation in environments beyond silicon. This motivates biological computing as an alternative, enabling efficient, resource-aware, and reconfigurable computing within living systems. This dissertation addresses these limitations by introducing a bacterial computing framework that models Gene Regulatory Networks (GRNs) as Gene Regulatory Neural Networks (GRNNs). The GRNN mirrors the structure and function of Artificial Neural Networks (ANNs) through gene-gene interactions across trans-omic layers, enabling natural, self-regulating information processing within living …

The Empathetic-Perverse: A Contemporary Exploration Of The Grotesque In Southern Gothic Literature, Halle Elizabeth Griggs

Electronic Theses and Dissertations Archive

Contemporary scholars and critics alike can agree that much of our understanding of Southern Gothic literature and its relation to the grotesque comes from Flannery O’Connor. O’Connor often portrays a transformation within that of grotesque characters (characters with moral flaws and/or physical disabilities). These transformations, depicted through use of pain, violence, and outlandish behavior, help to bring these grotesque characters closer to God, experiencing a sort of divine grace or redemption. Yet, often these grotesque characters are depicted in a way void of compassion. Despite describing fiction from the middle of the last century, most critics still rely on the …

Promiscuous Mutualisms: John Dupré And The Centrality Of Symbiosis In The Living World, Thomas Pradeu

Presidential Fellows Articles and Research

My goal in this chapter is to show that symbiosis, especially symbiotic interactions between ‘macrobes’ (non-microbial organisms) and microbes, is a central topic in John Dupré’s work. This topic is undeniably one of the topics by which Dupré has gained wide recognition among practicing scientists, in addition to his recognition within the philosophical community. I spell out why symbiosis has turned out to be a sort of ideal trope for Dupré, as it encapsulates many of his main personal themes—from promiscuous realism to process ontology. I then show that immunology offers one interesting and complementary entry point into microbial symbiosis …

Canada’S Contributions To International Legal Discourse: Gender, Genocide, And Neocolonial Investments (2015–2025), Heidi Matthews

Articles & Book Chapters

This chapter critically evaluates Canada’s major points of engagement with international law in the period between 2015 and 2025. In partnership with European and Commonwealth allies, Canada has been an active participant in several contentious cases at the International Court of Justice (ICJ), including against Myanmar, Syria, and Afghanistan. Canada has taken progressive legal positions in this litigation with respect to the interpretation and application of international law as it relates to sexual and gender-based crimes, as well as abuses committed against children. However, the past decade also reveals that Canada’s policy responses to its genocide and other crimes against …

Rural Youth In Time Of Climate Change: A Case Of Kajang, Indonesia, Fatwa Faturachmat, Andi Vika Faradiba Muin, Nurhady Sirimorok, Ishak Salim, Karno B. Batiran, Andi Mujetahid

Forest and Society

Global agriculture is deeply affected by climate change, and more so in rural areas of developing countries, where the local smallholder farmers are already facing pressures from market-induced problems. Although capable of absorbing a large number of youths, small-scale farming is shrinking mainly due to enclosures and price squeezes. Drawing on a case study of five villages in Indonesia that are part of the Kajang Indigenous Communities, we apply an extended sustainable livelihood approach (SLA) to examine the strategies adopted by rural youth in the face of deteriorating small-scale farming. We examine how local institutions and organizations, as well as …
