Research ArticleOpen accessIn the abstractAction of Calciotropic Hormones on Bone Metabolism-Role of Vitamin D3 in Bone Remodeling EventsCatharine Andresen, Ellen Olson, Chudy I. Nduaka et al.Vitamin D3 is known to have immunosuppressive effects that can be beneficial for treatment of immune disorders and transplant rejection, however therapeutic application is limited due to hypercalcemia and hypercalcuria. The goal of our studies was to explore both the acute and steady state effects of vitamin D3 on bone remodeling as potential limiting factors to broader use of vitamin … …American Journal of Immunology, Vol. 2, Issue 2 · 30 Jun 2006 · 8,816 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIntegrating Stochastic Properties into Traffic Flow Modeling: A Stimulus-Response ApproachKonate N’Golo, Mark Kimathi, Emile DanhoHighway traffic congestion, characterized by its inherent instability, has been extensively studied using deterministic models, providing valuable insights. However, these models often overlook the stochastic nature of driver behavior, a key factor that significantly impacts traffic flow. Recognizing this, a car-following model with discretionary lane changes to analyze their effect on traffic dynamics was introduced. While the mathematical results were … …Journal of Mathematics and Statistics, Vol. 20, Issue 1 · 19 Dec 2024 · 7,153 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling of Observer-Based Social Media Marketing for Saudi Arabia ConsumersMahmoud Alblowi, Omar Aloufi, Najmah Fallatah et al.Global change has been significantly amplified by the Internet's swift development of technology. The emergence of social media has marked a significant improvement in communication and information availability. Therefore, the social media marketing industry is a significant area used to advertise a wide range of products. In the Kingdom of Saudi Arabia (KSA), social media platforms have been widely used … …Journal of Computer Science, Vol. 19, Issue 7 · 11 Jun 2023 · 5,814 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMultilevel Mixed Analysis and Mapping on Divorce Problem in UAEFaisal G. KhamisDespite the wealth of research investigating the divorce problem in the developed countries, few and inconsistent studies investigated this problem at emirate-level in developing countries, such as United Arab Emirates (UAE). The Questions are raised whether divorce is changed over time and whether clustering in divorce exists within emirates in UAE. The objectives are to investigate the change in divorce … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 31 Oct 2016 · 7,296 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGas Atomization of Molten Metal: Part I. Numerical Modeling ConceptionGenaro Pérez-de León, Vincent E. Lamberti, Roland D. Seals et al.This numerical analysis study entails creating and assessing a model that is capable of simulating molten metal droplets and the production of metal powder during the Gas Atomization (GA) method. The essential goal of this research aims to gather more information on simulating the process of creating metal powder. The model structure and perspective was built through the application of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 10 Apr 2016 · 9,047 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Block-Based Multi-Scale Background Extraction AlgorithmSeyed Hashem Davarpanah, Fatimah Khalid, Maryam GolchinProblem statement: To extract the moving objects, vision-based surveillance systems subtract the current image from a predefined background image. The efficiency of these systems mainly depends on accuracy of the extracted background image. It should be able to adapt to the changes continuously. In addition, especially in real-time applications the time complexity of this adaptation is a critical matter. Approach: … …Journal of Computer Science, Vol. 6, Issue 12 · 6 Nov 2010 · 7,213 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling of Transient Heat Flux in Spark Ignition Engine During Combustion and Comparisons with ExperimentT. F. Yusaf, Sye Hoe, Fong et al.A quasi-one dimensional engine cycle simulation program was developed to predict the transient heat flux during combustion in a spark ignition engine. A two-zone heat release model was utilized to model the combustion process inside the combustion chamber. The fuel, air and burned gas properties throughout the engine cycle were calculated using variable specific heats. The transient heat flux inside … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,173 accessesView PDFCite
