Research ArticleOpen accessIn the abstractEmpowering Small Language Models With Chain of Thought and Parameter Efficient Fine Tuning for Efficient Deep ReasoningAryan Raina, Shiwani Gupta, Jagruti Jadhav et al.Small Language Models (SLMs) run faster and fit on modest hardware, yet solving multi-step logic problems has traditionally been difficult for them. This work investigates a systematic, multi-model framework that combines Chain-of-Thought (CoT) prompting with Low-Rank Adaptation (LoRA) parameter-efficient fine-tuning, and measures the contribution of each component independently. We evaluate three SLMs (TinyLlama-1.1B, Phi-3-mini-4k-instruct, and Qwen2.5-1.5B) using 1,164 training samples … …Journal of Computer Science, Vol. 22, Issue 8 · 8 Sep 2026 · 862 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Chain Mediating Role of Technology Self-Efficacy and Attitudes in Online Learning EnvironmentsJie Gao, Dolores D. Borras, Beverly T. CaigaThis study investigates the mediating role of technology self-efficacy and attitudes in online learning environments among university students. Specifically, we examined how students' technology self-efficacy, attitudes toward online learning, and perceptions of course appropriateness influence online learning outcomes. Data were collected via questionnaire survey from students enrolled in public and private universities (N = [specify number]). Structural equation modeling with … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Nested Digital Watermarking Scheme Using GARN with DWTEdward Yellakour Baagyere, Peter Awonnatemi Agbedemnab, Mohammed Akolgo, Strato Angsoteng BayitaaCopyright infringement is undoubtedly one of the major challenges in the film and TV industries over the years but has become even more pervasive lately as a result of technological advancement. This has made it possible to decode hitherto, hard-encoded, or encrypted multimedia content resulting in a lot of losses to companies in such industries. Digital watermarking, which is, a … …Journal of Computer Science, Vol. 20, Issue 10 · 30 Jul 2024 · 4,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgressive LDL Reduction to Very Low Levels Improves Dimeric Nitric Oxide Synthase, Nitric Oxide Bioavailability and Reduces Peroxynitrite in Endothelial Cells during HyperglycemiaR. Preston Mason, Hazem Dawoud, Samuel C.R. Sherratt et al.Circulating levels of glucose and LDL influence Endothelial Cell (EC) function in a highly interactive manner as evidenced by nitric oxide production and coupling of endothelial Nitric Oxide Synthase (eNOS) dimer. Here, we report on the status of eNOS function in Human Umbilical Vein Endothelial Cells (HUVECs) cultured under normo- and hyperglycemic (250 mg/dL) condition followed by exposure to increasing … …American Journal of Pharmacology and Toxicology, Vol. 14, Issue 1 · 2 May 2019 · 8,356 accessesView PDFCite
Review ArticleOpen accessIn the abstractCooperation in Rural Areas as a Local System Development OpportunityEmanuele Schimmenti, Giovanni Battista Collura, Giuseppina Migliore et al.The development of rural areas requires the adoption of technology innovation and market approach strategies without departing from the specific features of local production systems, such as agricultural practices and the wealth of knowledge of operators. It is even better the exploitation of these resources to characterize the competitive positioning of territorial systems. In this framework, the cooperative Rinascita, which … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 3 Jan 2018 · 8,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Elements at MP3RRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Mechatronic robotic systems are today widely used worldwide to ease human work, but especially where work is dangerous, in toxic, radioactive, chemical, explosive atmospheres, without air such as underwater or in the cosmos, or in places hard to reach the man. Robots can take the tedious repetitive work under any circumstances and they can perform a difficult operation for a … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 23 Nov 2017 · 7,566 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Stevia Consumption on Blood Pressure, Stress Hormone Levels and Anthropometrical Parameters in Healthy PersonsEmad A.S. Al-Dujaili, Husni Twaij, Yazan A. Bataineh et al.Stevia is a natural sweetener containing steviol glycosides known to be several times sweeter than sucrose. It is thought to have several beneficial properties though some evidence state it may have detrimental effects. The aim of this study was to investigate the potential beneficial or harmful effects of stevia consumption by exploring its effects on blood pressure, stress hormone levels … …American Journal of Pharmacology and Toxicology, Vol. 12, Issue 1 · 31 Aug 2017 · 25,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Biodiesel Production from Spent Palm Cooking Oil Using Fractional Factorial Design Combined with the Response Surface MethodologyS.M. Zakir Hossain, Nahid Sultana, Muhammad Faisal Irfan et al.Fractional Factorial Design (FFD) of the experiments combined with the response surface methodology was used to determine the optimum conditions for the production of biodiesel from Used Cooking Oil (UCO) in a batch reactor. Spent palm olein cooking oil was used as a raw material for biodiesel production as it is commonly used in most of the restaurants in Bahrain. … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 22 Nov 2016 · 8,443 accessesView PDFCite
Research ArticleOpen accessIn the abstractContribution of Remote Sensing in the Estimation of the Populations Living in Areas with Risk of Gully Erosion in Kinshasa (D.R. Congo). Case of Selembao TownshipKayembe wa Kayembe Matthieu, Ngoy Ndombe Alain, Makanzu Imwangana Fils et al.This paper proposes a methodology combining very high spatial resolution satellite image, GIS and field surveys to estimate the number of people living in areas at (high) risk of landslides or gully erosion in Selembao (Kinshasa). It also gives their socio-economic characteristics. Results show that 185,000 out of the 314,699 inhabitants estimated in Selembao (58.3% of the population) live in … …Current Research in Geoscience, Vol. 6, Issue 1 · 6 Jun 2016 · 8,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrologic Modeling to Evaluate the Impact of Hydraulic Fracturing on Stream Low Flows: Challenges and Opportunities for a Simulation StudySuresh Sharma, Aashish Shrestha, Colleen E. McLean, Scott C. MartinHydraulic fracturing (fracking) has been increasing in the eastern part of Ohio for the last few years leading to the increased stress on water resources, particularly on the hydrological low flows. Yet, evaluation of the various impacts of fracking on stream low flows using appropriate tools is still a challenging issue, even though significant progress has been achieved in recent … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 7 Aug 2015 · 10,414 accessesView PDFCite
