Exact Soliton Solutions Of The Nonlinear Time-Fractional Schrödinger Equation Via Atangana–Baleanu And M-Truncated Operators, Bahadır Kopçasiz, Fatma Nur Kaya Sağlam, Mehmet Şenol Mar 2026

Exact Soliton Solutions Of The Nonlinear Time-Fractional Schrödinger Equation Via Atangana–Baleanu And M-Truncated Operators, Bahadır Kopçasiz, Fatma Nur Kaya Sağlam, Mehmet Şenol

Mathematical Modelling and Numerical Simulation with Applications

The main objective of this work is to obtain exact soliton solutions for a nonlinear time-fractional equation model describing wave profiles arising in various physical systems. To derive different wave structures associated with the considered model, two analytical techniques are employed: the extended G'\G^2-expansion method and the modified auxiliary equation (MAE) approach. A wave transformation is applied to reduce the nonlinear time-fractional equation to a nonlinear ordinary differential equation (NLODE) by means of the M-truncated and Atangana-Baleanu (AB) fractional operators. Several classes of solutions, including exponential, hyperbolic, and trigonometric wave forms, are obtained. Over and above the analytical results, graphical …

What Is Alive? Students’ Conceptions Of The Traits That Unite Living Organisms, Jeremy L. Hsu, Meredith A. Dorner, Kate Hill Mar 2026

What Is Alive? Students’ Conceptions Of The Traits That Unite Living Organisms, Jeremy L. Hsu, Meredith A. Dorner, Kate Hill

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Biology is the study of life, but students often hold misconceptions about what it means to be alive, with children often associating life with movement. These misconceptions can lead to biases in what students think is alive, with younger children often not thinking of plants as living given their lack of discernable movement. Despite this past work, there have been no prior studies that we are aware of that have examined how students in introductory biology conceptualize what it means to be alive. Here, we draw upon a fortuitous dataset collected from an in-class activity done on the first day …

The Heavy Crown, Shared Throne: How Coleadership Tempers Ego And Sustains Leader Well-Being, Sam T. Hunter, Ares Boira-Lopez, Alexis D'Amato

Psychology Faculty Publications

Mitchell and colleagues (Reference Mitchell, Haslam, Burke and Steffense2026) provide a well-reasoned, sound, and thought-provoking case for why HR practices can promote or discourage narcissistic tendencies in leaders. Acknowledging their contribution, we offer two points of pushback and one point of extension based on those areas of pushback. The first point of pushback is that counter to the authors, we contend that hypercompetitive selection methods that seek to identify the best leadership candidate, although not ideal, are necessary. Do such processes (e.g., head hunting, in-depth assessment centers) admittedly have the potential to inflate individual egos and promote narcissistic …

Determining A Likely Mechanism Of Missingness In Repeated Measures Sleep Data From Wearable Fitness Trackers: Longitudinal Analysis, Kate Mobley, Kevin B. Gittner, Karen Nielsen, Lauren Matheny, Gita Taasoobshirazi, Charles Natuhamya, Monica H. Swahn

Faculty Articles

Background: Wearable fitness trackers have become a valuable tool in public health research due to their ability to collect large-scale, individual-level data at a low cost. Because of this, wearables have the potential to mitigate the urgent need for health research in low-resource settings. However, their use has been largely limited to high-income settings, and a major challenge remains: high rates of missing data. This problem may be exacerbated in low-resource environments where logistical and operational barriers further complicate data collection. Wearable sleep data collected in an urban informal settlement in Uganda during The Onward Project on Well-being and Adversity …

Faculty Research, Scholarly, and Creative Activity

To address high thermal loads and energy costs in Geothermal Road Snow-Melting Systems (GRSSs) within cold regions, this study optimizes energy efficiency through material-level intervention. We developed a composite anti-icing modifier synergistic with low enthalpy geothermal systems, comprising slow-release agents, anti-corrosive components, reinforcing materials, and active chloride salts. By regulating the thermodynamic boundary of the pavement, the freezing point is suppressed to −21 °C. This eliminates the requirement for positive pavement temperatures, significantly reducing the design thermal power. Chloride ion release patterns were analyzed via dissolution and 20-day soaking tests to evaluate structural durability. Results show optimal performance at a …

Propagation And Interaction Of Gravity Currents Induced By Successive Release Of Two Lock Fluids, Khem Prasad Bhattarai, Subhas Karan Venayagamoorthy Mar 2026

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 …

Application Of A Fuzzy Multi-Objective Defuzzification Method To Solve A Multi-Modal Transportation Problem, Qusay H Khalaf, Khalid Zeghaiton Chaloob Mar 2026

Application Of A Fuzzy Multi-Objective Defuzzification Method To Solve A Multi-Modal Transportation Problem, Qusay H Khalaf, Khalid Zeghaiton Chaloob

Muthanna Journal of Administrative and Economics Sciences

Multi-modal transportation systems are the logistics networks for global economy. Transportation systems are fraught with uncertainties that hinder the traditional deterministic models reaching the optimal performance. The main obstacle for traditional deterministic models is the uncertainties (e.g., fuel prices volatility, inaccurate transit-times prediction, and evolving environmental regulations). This paper proposes a novel method of fuzzy multi-objective defuzzification. It integrates a modified center of gravity (COG) technique with multi-objective linear programming (MOLP) to address the uncertainty challenges. Triangular fuzzy numbers and partitioning to sud-intervals generated crisp solutions to balance conflicting objectives: cost, time, and environmental sustainability. A four transportation-mode used as …

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 …

Implementation Of Direct Corpus Applications To L2 Collaborative Writing Pedagogy: The Impact On Learner Interaction, Written Output And Development, Ahmet Egemen Curuk Mar 2026

Implementation Of Direct Corpus Applications To L2 Collaborative Writing Pedagogy: The Impact On Learner Interaction, Written Output And Development, Ahmet Egemen Curuk

Electronic Theses and Dissertations Archive

This dissertation examines the implementation of direct corpus applications within L2 collaborative writing pedagogy and investigates their impact on learner interaction, as well as measurable gains in syntactic complexity, lexical complexity, and accuracy during collaborative writing and in subsequent individual writing. Although prior research has established the pedagogical value of corpus-based instruction and collaborative writing separately, little is known about how these approaches function when integrated, particularly with an emphasis on the learner experience and the interactional mechanisms that mediate learning. To address this gap, this dissertation adopts a mixed-methods design to explore how corpus-guided collaborative writing shapes dyadic interaction, …

Spacecube: Interactive Real-Time Uas Hyperspectral Processing, Thomas Pascarella Watson Mar 2026

Spacecube: Interactive Real-Time Uas Hyperspectral Processing, Thomas Pascarella Watson

Electronic Theses and Dissertations Archive

Hyperspectral cameras capture hundreds of data points per sample (pixel), thereby providing numerous advantages in remote sensing tasks. Many tasks can be effectively conducted with such a camera mounted on a small uncrewed aerial system (sUAS). However, obtaining results traditionally requires significant post-processing of captured data after flight, delaying insight. To mitigate the delay, this work proposes Spacecube, a program that implements a complete interactive hyperspectral processing pipeline. Spacecube's novel inverse georectification algorithm processes entire datasets in seconds, compared to hours for traditional methods, and eliminates pixel coverage artifacts. This allows immediate high-quality viewing and adjustment of captured flight data. …

Voltage Breakdown Strength And Energy Density Of Ceramic Srtio₃ At Cryogenic Temperatures From 295 K To 77 K, Hung Trinh, Alan Devoe, Fatih Dogan

Materials Science and Engineering Faculty Research & Creative Works

The low-temperature dependence of the DC dielectric breakdown strength (EBD) and the energy storage density (W) of capacitors, fabricated from high purity polycrystalline strontium titanate, were investigated in the temperature range from 295 K to 77 K. Test samples were constructed with a process similar to that used for multilayer ceramic capacitors (MLCCs). The permittivity, loss tangent, leakage current, and breakdown strength were measured as a function of temperature and voltage. Weibull statistical analysis was used to quantify breakdown distributions. Despite electric-field suppression of permittivity, breakdown strength increased significantly with decreasing temperatures, leading to enhanced energy density. The breakdown field …

Mathematical Modelling and Numerical Simulation with Applications

This research presents an extensive investigation of Ion acoustic soliton dynamics governed by a Beta-fractional Kadomtsev-Petviashvili-Burgurs (KPB) model. By engaging the planar dynamical system scheme in aggregation with the extended $(\phi, \psi)$ expansion, Kudryashov expansion, and the NMKM analytic schemes, we create a broad class of exact nonlinear pattern wave solutions. The local stability edifice of the fractional plasma model is explored through bifurcation theory, enabling the far-reaching classification of all admissible phase diagrams. Conforming Ion acoustic wave structures allied with every detour alignment are systematically assembled. Owing to the fractional and dissipative appearances of the model, an all-embracing assortment …

Mathematical Modelling and Numerical Simulation with Applications

In this work, the fractal-fractional Atangana-Baleanu derivative with the Mittag-Leffler kernel is employed to capture the memory and hereditary effects inherent to anthropogenic cutaneous leishmaniasis transmission dynamics. The Banach fixed-point theorem and contraction mapping principle are used to prove the existence and uniqueness of solutions, while Hyers-Ulam stability of the system is analyzed to demonstrate the robustness of solutions with respect to small perturbations. Using a nonlinear least-squares approach, model parameters and fractional order are estimated using epidemiological data from the World Health Organization. The basic reproduction number $R_0 = 0.53$ indicates that the disease is under control after adding …

Markov-Modulated Queueing Network For Mobile Traffic Aggregation With Threshold-Controlled Buffers, Anton A. Esin, Elmira Yu. Kalimulina

Mathematical Modelling and Numerical Simulation with Applications

We study the problem of data transmission from mobile platforms operating in high-speed transit between cellular base stations, under conditions of unstable and intermittent connectivity. Conventional queueing and connectivity models often fail to capture the combined effects of rapidly changing signal conditions, finite buffer capacity, and dynamic topology. We aim to develop a tractable yet expressive model that integrates stochastic link availability, queue dynamics, and buffer control. We propose a mathematical framework based on queues whose service intensities are modulated by a continuous-time Markov chain (CTMC) representing signal conditions along a high-speed trajectory. The core subsystem is a two-stage (aggregation …

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, …
