New Fiber And Graph Combinations Of Convex Bodies, Steven Hoehner, Sudan Xing

Mathematical Sciences Faculty Publications and Presentations

Three new combinations of convex bodies are introduced and studied: the fiber, chord, and graph combinations. These combinations are defined in terms of the fibers and graphs of pairs of convex bodies, and each operation generalizes the classical Steiner symmetral, albeit in different ways. For the fiber and chord combinations, we derive Brunn-Minkowski-type inequalities and the corresponding Minkowski's first inequalities. We also prove that the general affine surface areas are concave (respectively, convex) with respect to the graph sum, thereby generalizing fundamental results of Ye (Indiana Univ. Math. J. 14 (2014), 1-19) on the monotonicity of the general affine surface …

Of Photographs, Souvenirs, And Ticket Stubs: When Do Consumers Desire Mementos During An Experience?, Charlene Chu, Suzanne B. Shu

Business Faculty Articles and Research

Consumers often desire mementos of their experiential consumption, as reflected in common behaviors such as taking photos during a special event, purchasing souvenirs while on vacation, or keeping ticket stubs from a concert, but when do consumers desire mementos during an experience? This research examines the timing of the desire for mementos during an experience, and the conditions and motivations that prompt those memento timing decisions. We propose that the approaching end of an experience increases feelings of sadness and thus the desire for mementos at that time. However, for experiences that are easily repeatable, the approaching end of an …

Observations On Predation Of The Flatback Turtle Natator Depressus By The Saltwater Crocodile Crocodylus Porosus At A Major Rookery In Northern Australia, Casper Avenant, James Gee

Research outputs 2022 to 2026

Context: We examined predation by the saltwater crocodile (Crocodylus porosus) on the flatback turtle (Natator depressus), an Australian endemic, at Cape Domett, a significant nesting site in Cambridge Gulf, northern Australia, where crocodile populations have recovered since legislative protection was implemented in the 1970s. Aims: The investigation aimed to document crocodile predation on flatback turtles across hatchling and adult life stages, assess predation strategies, and evaluate ecological impacts on this genetically distinct turtle stock. Methods: Conducted over three Austral winters (2021–2023), the study utilised infrared videography, unmanned aerial vehicles, and beach patrols to observe predation events in a population of …

Thermo-Driven Structural And Optical Variations For The Improved Bidirectional Photodetection Of Ag2o@ Cdte Thin Films, Ahmed M. Nawar, Ahmed Ramzy, Shehab E. Ali, A. A.M. Farag, Ahmed M. El-Mahalawy

Nanotechnology Research Centre

Bidirectional photodetection is an emerging functionality in advanced optoelectronic systems, characterized by the ability of a photodetector to respond to the incident light under both forward and reverse biasing voltage. For this aim, a layer of silver oxide (Ag2O) is deposited on CdTe thin films, and then, directly, the fabricated Ag2O@CdTe samples on quartz and n-Si substrates are thermally annealed (from 100 to 400◦C). In general, the surface topography is driven by the post-annealing process; besides that, the crystallinity of Ag2O@CdTe samples is improved at 200◦C. The optical characteristics of transmittance and reflectance spectrophotometric measurements at normal incidence revealed a …

Improved Berezin Radius Inequalities For Functional Hilbert Space Operators, Mojtaba Bakherad, Ulaş Yamanci, Mohammad W. Alomari

Turkish Journal of Mathematics

The Berezin number of an operator S is defined by ber(S) = sup_λ∈Θ |Ŝ(λ)| = sup_λ∈Θ |⟨Sĸ̂_λ, ĸ̂_λ⟩|, where Ŝ(λ) = ⟨Sĸ̂_λ, ĸ̂_λ⟩ (λ ∈ Θ) is the Berezin transform of an operator S on the functional Hilbert space ℋ = ℋ(Θ) and ĸ̂_λ = ĸ_λ / ‖ĸ_λ‖ is the normalized reproducing kernel of ℋ. In this paper, we show an improvement of the classical Cauchy–Schwarz inequality involving the Berezin number. Moreover, some Berezin numbers inequalities are proven for invertible operators.

On Multiplicative Order Convergence And Multiplicative Order Continuous Operators, Hüma Gürkök, Bahri̇ Turan

Turkish Journal of Mathematics

Let A and B be two f-algebras. This paper establishes the theoretical framework for multiplicative order convergence, clarifying its definition, properties, and relations to other convergence types. This includes a detailed discussion on the conditions under which multiplicative order convergence and order convergence, as well as unbounded order convergence, mutually imply each other. We establish an extension theorem for multiplicative order continuous operators, similar to Veksler’s theorem for order continuous operators. As a result of this theorem, we derive the order structure of the space of multiplicative order continuous operators. We show that the space L_mo(A, …

The Action Of The Superposition Operator On Weighted Banach Sequence Spaces LP,Σ, Nermin Okičić, Fehim Dedagić

Turkish Journal of Mathematics

We consider a nonlinear superposition operator on weighted Banach spaces l_p,σ, where σ is the weighted function with the property that (∀n ∈ ℕ) σ(n) ≥ 1. We present the necessary and sufficient conditions for the action of the superposition operator from l_p,σ to l_q,τ, 1 ≤ p, q ≤ ∞, as well as the L-characteristic of the action of the considered operator.

Nonoscillatory Solutions Of Third-Order Nonlinear Dynamic Equations: Existence And Nonexistence, Özkan Öztürk, Elvan Akin, Nesli̇han Nesli̇ye Pelen

Turkish Journal of Mathematics

This paper investigates a third-order nonlinear dynamic equation on arbitrary time scales, a nonempty closed subset of the real numbers, unifying continuous and discrete analyses. We study the qualitative behavior of nonoscillatory solutions and their quasi-derivatives, focusing on their limiting behaviors. The existence of such solutions are established using improper integral criteria and Schauder’s and Knaster’s fixed point theorems. In addition, we establish the criteria for the nonexistence of nonoscillatory solutions. Furthermore, we prove the existence of Kneser-type solutions of the corresponding linear dynamic equation on isolated time scales, addressing an open problem in the literature. Several examples of theoretical …

Majorization Properties For Analytic Functions With Positive Real Part, Oya Mert

Turkish Journal of Mathematics

The majorization feature is important when investigating analytical functions’ geometric properties. The present work focuses on the majorization property for a general Ma-Minda type function class S^*_φ(γ, λ) of starlike functions of complex order, which is described with the Ruscheweyh differential operator. In the context of the main theorem, consequences are presented for various special functions φ having a positive real part. Furthermore, the Ruscheweyh differential operator extends a representation formula and investigates an upper-bound formula. Examples of upper bounds for analytic functions are also presented.

Structural Stability For Damped Nonlinear Wave Equations, Sevda Isayeva, Varga Kalantarov

Turkish Journal of Mathematics

We study the problem of continuous dependence on parameters for solutions to initial-boundary value problems for nonlinear strongly damped wave equations. Specifically, we consider three classes of equations: a strongly damped wave equation with a nonlinear damping term; a strongly damped wave equation incorporating both a nonlinear damping term and a nonlinear source term; and a strongly damped wave equation with a nonlinear source term and a linear weak damping term. For each class, we establish structural stability results, showing that the solutions depend continuously on the relevant parameters.

Application On Convolution For Fuzzy Differential Subordination Of Meromorphic Functions, Kholood Mohamed Alsager, Fethi̇ye Müge Sakar, Alina Alb Lupas, Sheza Mohamed El-Deeb

Turkish Journal of Mathematics

This paper investigates fuzzy differential subordinations involving meromorphic functions defined in the punctured unit disk. A novel operator based on the Hadamard product (also known as convolution) is introduced to establish new results in the theory of fuzzy differential subordination. This operator provides a generalized framework that extends classical analytic methods to the fuzzy setting, offering new insights into the geometric behavior of meromorphic functions under fuzzy conditions. Several sufficient conditions for fuzzy differential subordination are derived, and their connections to existing results are discussed. The findings contribute to the growing body of literature at the intersection of classical geometric …

(Α, Β)-Normal Differential Operators For First Order In Hilbert Spaces Of Vector-Functions, Zameddin I. Ismailov, Pembe İpek Al

Turkish Journal of Mathematics

In this article, the relationships between (α, β)-normality properties of the extensions of the minimal operator generated by the first-order differential operator expression in the Hilbert spaces of vector-functions in a finite interval and the variable operator coefficients of this differential operator expression are investigated. Then, the general form of all (α, β)-normal extensions of the minimal operator in these spaces is determined under the constraints obtained for the coefficient operators.

On Certain Subclasses Of Starlike And Convex Functions With Respect To T-Symmetric Points, Osman Altintaş, Ni̇zami̇ Mustafa

Turkish Journal of Mathematics

In this study, we defined for the first time a new subclass of stalike and convex functions in the open unit disk of the complex plane and we examined coefficiend upper bound estimates for this class.

The Generalization Of Rectifying Helices, Bülent Altunkaya

Turkish Journal of Mathematics

This work establishes connections between different classes of arbitrary speed rectifying helices. We further analyze how the involute of a space curve can exhibit spherical helicity and how the evolute can inherit rectifying properties, thereby providing an alternative characterization of these helices. These relationships, along with their interplay with involutes and evolutes, are supported by illustrative examples that offer deeper insights into their geometric properties.

Applications Of A New Linear Operator Involving Dziok-Srivastava Operator And Bessel Function Of The First Kind, Daniela Andrada Bardac-Vlada, Georgia Irina Oros

Turkish Journal of Mathematics

This study introduces a new linear operator constructed from the well-known Dziok–Srivastava linear hypergeometric operator, the Bessel function of the first kind, and convolution. Applying the new operator, a class of functions with positive real part is defined and investigated concerning inclusion relations, the necessary and sufficient conditions for functions to belong to this class, as well as starlikeness and convexity conditions. The properties of the new class to be convex of a certain order, close-to-convex and starlike of a certain order are highlighted and examples are also included to prove that the new outcome is applicable. The methods employed …

The Geometry Of Semislant Submersions Whose Total Manifolds Are Locally Conformal Kähler Manifolds, Çağrihan Çi̇men, Hakan Mete Taştan

Turkish Journal of Mathematics

We study semislant submersions whose total manifolds are locally conformal Kähler manifolds. We provide conditions for the total geodesicity and integrability of the distributions involved in the definition. Next, we establish a condition under which such a submersion is a Clairaut submersion. Finally, we obtain some optimal inequalities for a semislant submersion whose total manifold is Hopf space form.

The Impact Of A Six Week Exercise And Wellness Intervention For Perceived Stress Of Female Middle School Teachers, Tosha Bell

Doctorate in Kinesiology

The prevalence of classroom-related stress among female middle school teachers is a widely pressing issue with global implications. It is imperative to implement interventions that prioritize the overall health and well-being of these teachers. The primary objective of this randomized control trial was to investigate the incidence of perceived stress within female middle school teachers and the potential role of an exercise and wellness intervention in decreasing perceived stress levels. Nineteen female middle school teachers were randomly assigned to either an intervention group (n=10) or a control group (n=9). The study consisted of a six-week online exercise and wellness intervention …

Carbonation For Enhancement Of Fine Recycled Aggregate Applied To Mortar, Henrique Comba Gomes, Augusto Cesar Da Silva Bezerra, Conrado De Souza Rodrigues, Flavia Spitale Jacques Poggiali, Boksun Kim

School of Engineering, Computing and Mathematics

Some of the challenges faced by the construction industry related to sustainability are the generation of construction and demolition waste (CDW), environmental impacts caused by the demand for natural aggregates, and associated carbon (CO₂) emissions. One potential solution is recycling CDW as recycled aggregates (RA). Though, RA generally performs poorly compared to natural aggregates (NA) in concretes. Researchers suggest that CO₂ curing via accelerated carbonation may improve the properties of RA. However, further investigation is needed to understand the impact of CO₂ curing on mortar made with fine recycled aggregates (FRA). This study explores the effects …

A Federated Approach To Scalable And Trustworthy Financial Fraud Detection, Yaser Alhasawi, Aljwhrh Abdalaziz Almtrf, Muhammad Asad

School of Engineering, Computing and Mathematics

Financial fraud remains a critical challenge for digital banking, requiring detection solutions that ensure both scalability and data privacy. Traditional centralized approaches face limitations due to security risks and system bottlenecks. This paper proposes FedFraud, a novel federated learning (FL) framework that detects fraudulent transactions without sharing raw data. FedFraud introduces two key innovations: (i) a trust-aware client aggregation mechanism that assigns weights based on update reliability and (ii) an asynchronous communication protocol enabling clients to contribute updates independently. Evaluated on the Credit Card Fraud Detection dataset under a nonidentically distributed (non-IID) data setting where client data distributions differ significantly, …

Patterns Of Resilience, Patterns Of Tragedy: Perspectives From Inside And Outside To Theorize Beneficial Interventions Serving Urban African American Youth Struggling With Community Violence, Katherine Tyson Mccrea, Kevin Miller, Amzie Moore, Heather L. Watson

Social Work: School of Social Work Faculty Publications and Other Works

Community violence, defined as violence perpetrated in community as opposed to home settings, is a salient social problem, causing terror and tragedy, especially in urban, low-income communities of color. Interventions supporting youth struggling with community violence have been insufficiently studied and theorized, especially from strengths-focused, culturally relevant standpoints in the context of contemporary social policies. This paper outlines psychodynamic theoretical models for services that have been developed via participatory research and provided for 19 years for over 1000 youth. Then, to understand how youth make use of the programs from an “inside” perspective, four intensive case examples are described. From …

A Qualitative Exploration Of Child, Caregiver, And Clinician Perspectives On Mental Health In Children With Osteogenesis Imperfecta, Justin H Qian, Andrew D Wiese, Clarissa Gonzalez, Whitney S Shepherd, Hannah Cho, Gianna M Colombo, Julia M Morales, Selena Guo, Kristin M Kostick-Quenet, Dianne Nguyen, Sophie C Schneider, Kara Ayers, Members Of The Bbdc, Marie-Eve Robinson, Chaya N Murali, Brendan Lee, V Reid Sutton, Eric A Storch

Center for Medical Ethics and Health Policy Staff Publications

Osteogenesis imperfecta (OI) is a heritable connective disorder with clinical manifestations including bone fragility and short stature. Previous research identified psychosocial themes related to mental health among children with OI and their caregivers, such as independence, social isolation, depression, and anxiety. Several studies have also examined clinicians of individuals with OI for their perspectives on mental health among their patients. However, no known studies have compared psychosocial themes among all three participant groups concurrently. This qualitative study examined mood and anxiety, along with risk and protective factors, from perspectives of youths, parents, and clinicians. Semi-structured interviews were conducted, which were …

Wave Intensity Analysis With Exercise Identifies Impairments In Pulmonary Hypertension, Christopher G. Lechuga, Farhan Raza, Mitchel J. Colebank, Claudia E. Korcarz, Jens C. Eickhoff, Naomi C. Chesler

Faculty Publications

Wave intensity analysis provides a novel approach to understanding the dynamic interactions between the right ventricle and pulmonary vasculature, particularly in pulmonary hypertension, a condition characterized by elevated pulmonary arterial pressures and vascular remodeling. This prospective study used wave intensity analysis to evaluate right ventricular and pulmonary vascular mechanics in 22 participants with pulmonary hypertension (including precapillary, isolated postcapillary, and combined pre/postcapillary pulmonary hypertension), and three without pulmonary hypertension. Forward and backward compression and decompression waves were quantified at rest and during incremental exercise (25, 50, and 75 W). Relationships between metrics of wave intensity analysis, hemodynamics, right ventricular function, …

Department of Psychiatry and Human Behavior Faculty Papers

BACKGROUND: Exploring the connection between climate change awareness and overall well-being is crucial, particularly in how it impacts both the environment and mental health. The mental health consequences of climate change and its awareness have not been thoroughly examined, especially in the U.S. In this study, the relationship between awareness of climate change and depression or anxiety among U.S. adults was explored. Similarly, the role of climate change awareness has not been explored in relation to mental health concerns.

METHODS: Based on the HINTS-6 dataset, a nationally representative, cross-sectional survey conducted by the National Cancer Institute, a variety of statistical …

A Multicriteria Model For Assessing Item Importance And Risk Using Operational Data From Military Supply Chains, Manuel D. Rossetti, Juliana Bright, Andrew Freeman, Anna Lee, Anthony Parrish

Industrial Engineering Faculty Publications and Presentations

This paper is motivated by the need to assess the risk profiles associated with the substantial number of items within military supply chains. The scale of supply chain management processes creates difficulties in both the complexity of the analysis and in performing risk assessments that are based on the manual (human analyst) assessment methods. Thus, analysts require methods that can be automated and that can incorporate on-going operational data on a regular basis. Design/methodology/approach

The approach taken to address the identification of supply chain risk within an operational setting is based on aspects of multiobjective decision analysis (MODA). The approach …

Reining In Plasticulture From Land To Sea: Pacific Northwest (Usa) Perspectives On Agriculture And Aquaculture, Susanne M. Brander, Gail A. Langellotto, Minal T. Mistry, Sebastian L. Singleton, Mackenna A. Hainey, Lauren M. Kashiwabara, Kelsey Arthur, Elise F. Granek, Kervelle Baird, Ricardo Palazuelos, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

Plastic use in food production—known as plasticulture—has transformed agriculture and aquaculture globally. Plasticulture gained momentum in the mid-20th century with the development of novel plastic materials, and by 2009, U.S. farmers used over 200 million pounds of plastic films annually. Though plastics have increased yields and efficiency, they now pose environmental hazards through the release of microplastics (MPs) and chemicals. Despite extensive documentation of MPs in the environment, their role in U.S. food production and impacts on crop, livestock, and aquaculture health remain underexplored. In regions like the Pacific Northwest (PNW), with robust agricultural and aquaculture sectors, plastics from films, …
