A Mathematical Model On The Temporal Dynamics Of Aviation Competitive Pricing, Tichaona Chikore,, Farai Nyabadza,

Journal of Aviation/Aerospace Education & Research

This study investigates the competitive dynamics of airport pricing using U.S. airport data to validate the findings. It employs linear and nonlinear ordinary differential equation models to analyze the influence of competitive interactions and internal factors on pricing decisions. The methodology involves parameter estimation via optimization techniques and quantile regression to capture heterogeneity across market segments. Mathematical analysis and simulation results show that if competitive coupling coefficients are low then there is weak competitive influence on pricing, with airports’ pricing largely driven by internal factors. Also, if the adjustment rates exhibit consistency across airports then internal dynamics are dominant in …

Short Term Hemodynamic Effects Of Atrial Fibrillation In A Closed-Loop Human Cardiac-Baroreflex System, Oluwasanmi Adeodu, Michelle Gee, Babak Mahmoudi, Rajanikanth Vadigepalli, Mayuresh V. Kothare

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Atrial fibrillation (AF) remains the leading cardiac cause of stroke and AF-related death rate in the United States has been increasing for over twenty years. While the effect of standalone AF on heart rate is well established, there is a lack of clarity on its impact on other critical hemodynamic metrics. This is ostensibly due to interaction with other common comorbidities, especially hypertension. In addition, AF has a complex relationship with the state of the baroreflex. Evidence indicates that baroreflex sensitivity (BRS), the ability of the intrinsic cardiac control system to initiate parasympathetic response, is suppressed during AF. Therefore, a …

Individual Open Access Articles

Pressure ulcers, also known as pressure sores, are a common and preventable complication among mobile patients, resulting from sustained pressure on specific body areas. Manual repositioning is the primary strategy for prevention, but it is physically stressful, time-intensive, and not uniformly performed by care providers. Ripple mattresses provide passive pressure redistribution; however, manual tuning is still necessary and requires an automated approach. This concept paper discusses the design of Comforturn, a smart mattress system capable of automating patient turning with a programmable side tilt and wave-like motion. The goal is to lessen caregivers' work burden and increase patient safety and …

How Social, Behavioral, And Policy Factors Impact Water Satisfaction And Management In Urban Areas, Rafi Haikal, Thoriqi Firdaus, Siti Hilya Nabila, Rizqi Shafira Chairunnisa

Journal of Environmental Science and Sustainable Development

The issue of water management in Indonesia’s specific urban contexts, specifically in Surabaya as an industrial hub and Bali as a tourist destination, is of paramount importance due to its impact on public health and environmental sustainability. This study analyses water management and conservation factors by comparing two distinct urban areas. The research design employs Partial Least Squares Structural Equation Modelling (PLS-SEM), which involves a specialised approach for analysing the complex relationships between variables. The results of the analysis indicate that community attitudes in Surabaya, facilitated by infrastructure and technology, significantly predicts intention to perform (β=0.334, p<0.001) and water management satisfaction (β=0.409, p<0.001). In contrast, collaboration with the government enhances environmental constraints (β=0.285, p<0.003) and water management satisfaction (β=0.140, p<0.044). In Bali, where water management is based on traditional practices, community attitudes do not significantly affect water management satisfaction (β=0.095, p>0.431). Still, perceived …

Constraining Deviations From The Kerr Metric Via A Bumpy Parametrization And Particle Swarm Optimization In Extreme Mass-Ratio Inspirals, Xiaobo Zou, Xingyu Zhong, Wen-Biao Han, Soumya D. Mohanty

Physics & Astronomy Faculty Publications

The measurement of deviations in the Kerr metric using gravitational-wave observations will provide a clear signal of new physics. Previous studies have developed multiple parametrizations (e.g., “bumpy” spacetime) to characterize such deviations in extreme mass-ratio inspirals (EMRIs). These approaches often rely on the Fisher information matrix (FIM) formalism to quantify the constraining power of future space-borne gravitational-wave detectors, such as LISA and Tianqin. For instance, using the analytical kludge waveform model under varying source configurations, such methods have achieved constraint sensitivity levels ranging from 10−4 to 10−2 on the dimensionless bumpy parameter 𝛿⁢˜𝑄 for LISA. In this paper, we advance …

Faculty Publications

Advances in ultra‐intense laser technology have increased repetition rates and average power for chirped‐pulse laser systems, which offer a promising solution for many applications including energetic proton sources. An important challenge is the need to optimize and control the proton source by varying some of the many degrees of freedom inherent to the laser‐plasma interactions. Machine learning can play an important role in this task, as our work examines. Building on our earlier work in Desai et al. 2024, we generate a large ∼1.5 million data point synthetic data set for proton acceleration using a physics‐informed analytic model that we …

Effects Of Hydrological Connectivity On Created Marsh Sustainability, Katie Swann

LSU Master's Theses

While efforts are being made to curb the high rate of coastal land loss in Louisiana, and even to restore ecosystem services and functions, it is generally accepted that restoration of these areas and functions is not a one-to-one value. It may take decadal time scales to reach efficient functional processing of nutrients and carbon storage rates, which may never reach true capacity comparable to similar naturally-organized systems. Although it is imperative to preserve these areas, restoration of ecosystem services and biogeochemical processes of coastal wetlands are preferable to future without action scenarios. Effectively directing the use of the limited …

Effects Of Prematuration Treatment On Developmental Competence Of Domestic Cat Oocytes, Victor F. Medina

LSU Master's Theses

Wild felids are experiencing population declines because of anthropogenic factors. As a result, there is a need for ex situassisted reproductive technologies (ART) for captive wild felids. Fortunately, domestic cats are an excellent model for developing ART for other felids. The aims of this thesis were to evaluate the potential effects of “holding” oocytes for 18 hours and different media sources, mimicking transport for ART on oocyte development and competence for ART. In the first study, 320 cumulus oocyte complexes (COCs) were allotted to 4 groups: group 1 COCs were fixed and DNA stained shortly after collection; group 2 …

Functional Cellulose Nanomaterials In Value-Added Applications, Mohammad Shayan

LSU Doctoral Dissertations

Cellulose nanomaterials (CNMs), including cellulose nanocrystals (CNCs) and cellulose nanofibrils (CNFs), offer potential value-added applications. This dissertation explores their versatility through three applications. In the first application, CNCs and CNFs were combined to create a pH-sensitive film by immobilizing anthocyanins from red cabbage extract (RCE). The addition of RCE altered the suspension's rheological, optical, and mechanical properties, with films containing 30 wt.% RCE exhibiting optimal performance and rapid pH responsiveness for seafood packaging. The second application addressed zinc dendrite growth and short circuits in aqueous zinc-ion batteries (ZIBs) by fabricating a hybrid NFC/Al(OH)₃ /PTFE protective layer for zinc anodes. …

Existence, Uniqueness, Stability And Exact Expression Of Periodic Traveling Wave Solutions Of The Higher-Order Cubic-Quintic Nonlinear Schrödinger Equation, Nan Wang, Yuqian Zhou, Zhijun Qiao

School of Mathematical & Statistical Sciences Faculty Publications

In this paper, the high-order cubic-quintic nonlinear Schrödinger equation is considered. By overcoming the difficulties caused by its non-integrability, we completely explore the existence, uniqueness and stability of the limit cycle of the equation. It enables us to accurately give the explicit parameter representation of its periodic wave solution in a special form for the first time. These results provide not only a new idea of obtaining periodic solutions in complex nonlinear systems, but also the important theoretical support for understanding related wave phenomena.
