Research ArticleOpen accessEvery word in the titleExploring the Relationship Between Skin Barrier Function, Sensitivity, and Repair MechanismsXiaoqing Yan, Yusong Shi, Jiguang YangFor healthy skin, the skin's barrier function must remain maintained. Many different molecular while immunological signaling mechanisms are involved in skin barrier control. The control of a healthy skin barrier, particularly acid mantle maintenance and proper amounts of ceramides, may help dermatologists develop remedies for skin barrier disruption disorders. In contrast, new medicines could focus on signaling pathways to offer … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,905 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluating Barriers to the Adoption of Augmented Reality-based Applications in Education System: DEMATEL ApproachMonika Nijhawan, Nidhi Sindhwani, Sarvesh Tanwar, Shishir KumarAugmented Reality (AR) is an emerging technology that enhances user perception by overlaying virtual information onto the physical world. In educational contexts, AR integration has demonstrated potential to improve learning engagement, motivation, and conceptual understanding among students. However, teachers face numerous challenges when incorporating AR technologies into classroom instruction, including technical difficulties stemming from inadequate training, resistance to technology adoption, … …Journal of Computer Science, Vol. 21, Issue 10 · 17 Dec 2025 · 2,422 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Carboxyl-Functionalized Single Walled Carbon Nanotubes on the Interfacial Barrier Height of Malachite Green Dye Based Organic DeviceSudipta Sen, Nabin Baran ManikIn this study, we have estimated the interfacial barrier height (ɸb) of Indium Tin Oxide (ITO) coated glass/Malachite Green (MG) dye/Aluminium (Al) based organic device and subsequently we have also observed the effect of carboxylfunctionalized SWCNT (COOH-SWCNT) on the ɸb. Presence of COOH-SWCNT reduces the interfacial barrier height as SWCNT acts as filler and provides easy path for charge percolation. … …Physics International, Vol. 10, Issue 1 · 31 Jul 2019 · 12,400 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparative Study on Barrier Option Pricing using Antithetic and Quasi Monte-Carlo SimulationsNneka Umeorah, Phillip MasheleMonte-Carlo simulations have been utilized greatly in the pricing of derivative securities. Over the years, several variance reduction techniques have been developed to curb the instability, as well as, increase the simulation efficiencies of the Monte-Carlo methods. Our approach in this research work will consider the use of antithetic variate techniques to estimate the fair prices of barrier options. Next, … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 9 May 2018 · 8,798 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,765 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficient Monte Carlo Algorithm Using Antithetic Variate and Brownian Bridge Techniques for Pricing the Barrier Options with Rebate PaymentsHasan AlzubaidiThe down-and-out call barrier option with rebate payment on dividend-paying stock is simulated using a new version of the Monte Carlo algorithm. The standard Monte Carlo method for simulating such an option suffers from two sources of errors: Hitting time error inherent from time stepping and the Monte Carlo statistical error. We present a modified version of Monte Carlo method … …Journal of Mathematics and Statistics, Vol. 12, Issue 1 · 22 Feb 2016 · 8,264 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreliminary Evaluation of a Permeable Reactive Barrier for Reducing Groundwater Nitrate Transport from a Large Onsite Wastewater SystemCharles Humphrey, Sushama Pradhan, Eban Bean et al.A permeable reactive barrier was installed between a large Onsite Wastewater System (OWS) and a monitoring well located down-gradient from the OWS. Groundwater samples from the well had shown elevated and increasing concentrations of NO3--N (>20 mg L-1 for 2 years). The barrier was constructed using woodchips from various tree species that were placed in a trench excavated to approximately … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 25 Aug 2015 · 7,375 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInvolvement of Bone Marrow Megakaryocytes in the Formation of the Bone Marrow-Blood Barrier in Transgenic MicePawel Laskowski, Karol Ostrowski, Beata Klim et al.Mature cell release takes place through the hypothetical barrier- the bone marrow-blood barrier. It consists of blood vessels and cells that surround them. Such cells are, among others, megakaryocytes. They are involved in the release of platelets or other cellular components of blood. The amount and the development of megakaryocytes and thus the maturity of barrier depends on many factors. … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 3 · 19 Sep 2013 · 7,185 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProbiotics the Good Neighbor: Guarding the Gut Mucosal BarrierR. K. Rao, D. B. Polk, A. Seth, F. YanProblem statement: The disruption of gut barrier function plays a crucial role in the pathogenesis of not only gastrointestinal diseases, but also the diseases of liver and other organs. Mucosal protective factors that preserve the gut barrier integrity are beneficial in the prevention and treatment of such diseases. Probiotics is a group of helpful bacteria that protect the gastrointestinal mucosa … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,417 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy.
