Research ArticleOpen accessIn the keywordsExogenous Pyocyanin Alters Pseudomonas aeruginosa Susceptibility to CiprofloxacinGary D. Grant, Tian Tian Zhang, Lee S. Gloyne et al.This in vitro cell-based study identified the contributing role of pyocyanin in the resistance of Pseudomonas aeruginosa to ciprofloxacin. Problem statement: P. aeruginosa is the major pathogen in the Cystic Fibrosis (CF) lung with pyocyanin being a critical component of its virulence. Prevalence is high and, once acquired, chronic infection is difficult to eliminate. Ciprofloxacin remains a crucial oral agent … …Current Research in Microbiology, Vol. 1, Issue 1 · 30 Jun 2010 · 8,800 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBackscattered Acoustic Energy by Monobubbles Experimental Approach and Statistical Study of the AttenuationAli Khelil, Claude ManteProblem statement: As the number of air bubbles in the sea is very high, they are so many acoustic diffusers who make illegible the recordings the purpose of which is to quantify the alive bodies. The signals backscattered by air bubbles constitute a parasite in offshore recordings and must be eliminated. It is planned to finalize techniques allowing the localization … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,585 accessesView PDFCite

Research ArticleOpen accessIn the abstractAnalyzing User Expectations and Usability Alignment in Augmented Reality Using Principal Component Analysis and RegressionTenia Wahyuningrum, Aditya Tama Isdiarto, Robert Hendra Yudianto, Rajermani ThinakaranUnderstanding visitor expectations is crucial for developing user-centered Augmented Reality (AR) applications for cultural heritage. This study investigates the relationship between visitor expectations and perceived usability of the Mooi Indie AR painting application using Principal Component Analysis (PCA) and regression analysis. Initial data were collected from 78 participants, and PCA reduced eight expectation variables into three principal components, which explained … …Journal of Computer Science, Vol. 22, Issue 10 · 27 Oct 2026 · 138 accessesView PDFCite
Research ArticleOpen accessIn the abstractLess Biased Approach for Sandstone Pore SegmentationDaffa Abiyyu Murtadha Kurnia, Iman Herwidiana KartowisastroReservoir characterization is a fundamental process in estimating reserves within petroleum and hydrogeological systems, where the precise determination of pore space dictates the validity of fluid flow models. Although X-Ray Computerized Tomography (XRCT) has become the standard non-destructive evaluation method for visualizing the internal structure of rocks, the data interpretation process still faces challenges during the image segmentation stage. Conventional … …Journal of Computer Science, Vol. 22, Issue 6 · 15 Jun 2026 · 1,196 accessesView PDFCite
