Optimal Control And Bifurcation Analysis Of A Predator–Prey Model With Self-Limiting Growth And Predator Disease, Dipo Aldila, Muhammad Akmal Fasya, Bevina D. Handari, Chidozie Williams Chukwu, Olumuyiwa James Peter

Mathematical Modelling and Numerical Simulation with Applications

We propose and analyze an eco-epidemiological predator–prey model that incorporates self-limitation and disease transmission within the predator population. The model is formulated as a system of ordinary differential equations describing logistic prey growth under the interspecific interaction with the predator. On the other hand, the predator population is divided into susceptible and infected classes, whose growth is constrained by prey availability. Three biologically relevant equilibria are identified: predator extinction, disease-free coexistence, and coexistence with endemic disease. The existence and stability of these equilibria are determined by key ecological and epidemiological thresholds, including the basic reproduction number. Using numerical continuation methods, …

Measuring Market Risk Through Entropic Var, Dragomir Nedeltchev, Tsvetelin Zaevski

Mathematical Modelling and Numerical Simulation with Applications

The article aims to measure the market risk beyond the basic risk measures like the Value-at-Risk (VaR) and the Expected Shortfall (ES). The Entropic Value-at-Risk is selected among the available measures based on its advantages -- it is the coherent upper bound of the VaR and ES. This risk measure is applied to the classical Black-Scholes model as well as to some more realistic ones, such as the exponential tempered stable model (the log-returns are presented by a tempered stable L\'evy process), the stochastic volatility model of Heston, its jump extension of Bates, and another stochastic volatility model but with …

Nursing Students’ Attitudes About Correcting Health Misinformation On Social Media, Heather Ann Hill

Walden Dissertations and Doctoral Studies

Health misinformation on social media is a global public health concern. Research has shown that health misinformation causes significant harm in communities, especially for vulnerable populations with existing health disparities. Nurses have been urged to play a more significant role in combating health misinformation. Existing research has shown that nurses are hesitant to correct health misinformation on social media, but attitudes among current nursing students have not been examined. The purpose of this qualitative descriptive study was to explore nursing students' attitudes about correcting health misinformation on social media. Guided by Ajzen’s theory of planned behavior and Paterson and Zderad’s …

Propagation And Interaction Of Gravity Currents Induced By Successive Release Of Two Lock Fluids, Khem Prasad Bhattarai, Subhas Karan Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study investigates the dynamics of sequentially released gravity currents in a lock-exchange configuration consisting of two lock fluids using high-resolution numerical simulations and compares them with the classical single-lock exchange. The results demonstrate that, in a two-lock-fluid configuration, the overtaking of the lighter lock current by the heavier lock current alters the current's front dynamics, leading to complex velocity transitions. Before overtaking occurs, the front propagation is slower than in the classical single-lock-fluid case because of lower density contrast, but after overtaking, the heavier lock fluid accumulates at the head region of the current and enhances its speed. The …

The Link Between Atrial Fibrillation And Gastroesophageal Reflux Disease - Pathophysiology, Emerging Evidence And Treatment Options, Wojciech Jakub Bajda, Jakub Juszczyk, Negin Fani, Dongwoo Kang, Jerzy Gregorczyk

Journal of the Hong Kong College of Cardiology

Gastroesophageal reflux disease (GERD) and atrial fibrillation (AF) are common conditions that significantly impact gastrointestinal and cardiovascular health. Emerging evidence suggests a bidirectional relationship between these conditions, mainly driven by inflammation and vagal nerve stimulation. Shared risk factors include obesity, obstructive sleep apnea, and hiatal hernias. This review explores the underlying pathophysiological mechanisms that may link GERD and AF, focusing on the roles of autonomic dysregulation, systemic inflammation, and mechanical interactions that may cause symptoms for both diseases. Lifestyle modifications including weight management, along with pharmacological treatments like proton pump inhibitors, have shown promise in managing the symptoms of both …

Approach To Management Of Grown-Up Cyanotic Congenital Heart Disease, Pak-Cheong Chow

Journal of the Hong Kong College of Cardiology

Despite of advances in cardiac and surgical care, some children with complex congenital heart disease remain cyanotic in adulthood. The grown-up cyanotic congenital heart diseases are heterogeneous due to their underlying cardiac anatomy and physiology. Other than cardiovascular problems, they patients are also faced with multi-system complications in the long run. Therefore, these patients need nuanced and comprehensive assessment, regular follow-up monitoring, and multi-facet management. In this article, the types and classification of cyanotic congenital heart diseases, the multi-system complications and the approach to assessment and treatment will be presented.

On Links Between A Theorem Of Schoenberg, Rohlin Decompositions Of Measures, The Bochner-Minlos Theorem And The Fock Space, Daniel Alpay, Paula Cerejeiras, Palle Jorgensen, Uwe Kaehler

Mathematics, Physics, and Computer Science Faculty Articles and Research

The main goal of this paper is to gain new results in stochastics by drawing on, and combining, different areas that are normally not considered to be related. Thus, in this paper we extend the previous class of Gaussian-like functions ML which will allow for future generalized stochastic processes in infinite dimensional analysis. We show that an approach similar to the one by the classical Bochner-Minlos theorem for the white-noise case can be achieved by using Gaussian-like functions belonging to a large family -the ML_r classes (0 < r ≤∞). We show how Schoenberg’s theorem for positive definite functions on a Hilbert space allows to go beyond the classical setting of Bochner-Milnos theorem. Furthermore, we show that the application of the Rohlin’s disintegration theorem allows for a decomposition of the associated probability measures , see Theorems 3.2 and 4.3. We end this paper with several important examples of functions in these classes ML_r and provide some interesting counterexamples, e.g. Theorem 7.4, to get a …

Quantum Indiscernibility And Perspectivalism, Emily Adlam

Mathematics, Physics, and Computer Science Faculty Articles and Research

It has often been suggested that similar quantum particles may be a counterexample to the principle of the Identity of Indiscernibles. In this article, I discuss the status of indiscernibility in a perspectival approach to quantum mechanics. I argue that adopting an internal physical perspective can have the effect of making entities discernible even if they are not discernible relative to external reference frames, and thus perspectivalism offers a new way to understand the physical meaning of weak discernibility. I discuss whether this approach is circular, and I consider whether the reference frames involved are physically meaningful. I conclude that …

Quantum Superpositions Of Conscious States In A Minimal Integrated Information Model, Kelvin J. Mcqueen, Ian T. Durham, Markus P. Müller

Philosophy Faculty Articles and Research

Could there be quantum superpositions of conscious states, as suggested by the Wigner’s friend thought experiment? Mathematical theories of consciousness, notably integrated information theory (IIT), make this question more precise by associating physical systems with both quantitative amounts of consciousness and structural characterizations of conscious states. Motivated by a recent proposal that ties wave-function collapse to integrated information, we construct a simple quantum circuit that would, on that proposal, place a minimal system—a feedback dyad—into a superposition of states that differ in their associated conscious states. This “Schrödinger’s dyad” provides a controlled setting for evaluating a central desideratum of consciousness-based …

Non-Hermitian Sl (3, C) Three-Mode Couplers, B. M. Rodríguez-Lara, Hamed Ghaemi-Dizicheh, Shahram Dehdashti, Andreas Hanke, Ahmed Touhami, J. Nötzel

Physics & Astronomy Faculty Publications

Photonic systems with exceptional points, where eigenvalues and corresponding eigenstates coalesce, have attracted interest due to their topological features and enhanced sensitivity to external perturbations. Non-Hermitian mode-coupling matrices provide a tractable analytic framework to model gain, loss, and chirality across optical, electronic, and mechanical platforms without the complexity of full open-system dynamics. Exceptional points define their spectral topology, and enable applications in mode control, amplification, and sensing. Yet N -mode couplers, the minimal setting for N th-order exceptional points, are often studied in specific designs that overlook their algebraic structure. We introduce a general sl(N , C) framework for arbitrary …

Effects Of Types And Amount Of Organic Matter On The Engineering Properties Of Soil, Afaq H. Malleh, Mohammed Y. Fattah, Hussein H. Karim

Engineering and Technology Journal

Organic soils exhibit highly variable geotechnical behavior due to differences in the type, content, and decomposition state of organic matter, which are often inadequately distinguished in engineering practice. This study investigates the influence of organic matter origin on soil behavior through a comparative analysis of sapric organic soils and sewage sludge soil tested under identical one-dimensional consolidation conditions. Laboratory tests included physical characterization, standard consolidation tests under vertical stresses of 200 kPa and 800 kPa, post-consolidation organic matter measurements, and microstructural analyses using SEM–EDS and XRD. The results show that increasing sapric organic matter content from 23% to 35% led …

The Secret Of Smerdyakov, Abigail M. Munzar

Global Tides

This paper analyzes the mysterious character of Pavel Smerdyakov from Dostoevsky’s novel, The Brothers Karamazov, by examining his loveless upbringing, motives for murdering Fyodor Karamazov, and his final conversations with Ivan Karamazov, to argue that Smerdyakov committed suicide out of guilt from his crime. Smerdyakov may have had a potential conversion to Christianity which would have triggered an identity crisis in which he was tormented between accepting Christ’s love and hanging on to his lifelong hatred. Thus, he would have committed suicide out of remorse from his sin like the biblical Judas and an inability to choose between conversion or …
