Research ArticleOpen accessIn the abstractRelationship between Streptococcus gallolyticus Infective Endocarditis and Pre-Neoplastic Colorectal LesionsPau Vilardell, Sergio Moral, Josep Maria Frigola et al.Colorectal cancer is associated with Infective Endocarditis (IE) due to specific gut pathogens, such as Streptococcus gallolyticus subspecies, that use tumor presence as a point of blood entry. However, the association between Streptococcus gallolyticus related IE and pre-cancerous colorectal lesions like dysplastic adenomas is unclear. Seventy-one patients diagnosed with IE who underwent colonoscopy in the extension study during admission were … …American Journal of Infectious Diseases, Vol. 17, Issue 3 · 28 May 2021 · 7,131 accessesView PDFCite
Literature ReviewOpen accessIn the abstractMycobacterium Abscessus Native Tricuspid Valve Endocarditis. Is a Six-Week Course of Combination Antibiotic Therapy Enough?Rabindra Ghimire, Dora Lebron, William Matthew Wooten et al.A 24-year-old Caucasian woman with a history of intravenous drug abuse and multiple hospital admissions for substance abuse related medical problems presented with pneumonia and was discharged home on oral antibiotics. Three days later, her blood culture grew acid fast bacilli, which was subsequently identified as M. abscessus subspecies abscessus. Transthoracic and transesophageal echocardiogram (TTE and TEE respectively) was suggestive … …American Journal of Infectious Diseases, Vol. 16, Issue 1 · 20 Feb 2020 · 7,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Role of Migratory Quail in Spreading of Some Zoonotic Pathogens in EgyptAhmed I. Youssef, Dalia H. MansourThis study aimed to illustrate the potential role of wild migratory quails in the epidemiology of some zoonotic pathogens in Egypt. Ninety four apparently healthy migratory quails were collected from public markets after being trapped during hunting season from the North Sinai. Oral, cloaca and organs (liver, lung and heart) swabs were collected for bacteriological and viral examination. Bacteriological examination … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 13 Dec 2014 · 7,530 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTATIONARY CONNECTED CURVES IN HILBERT SPACESRaed Hatamleh, Ahmad Qazza, Hatim MigdadiIn this article the structure of non-stationary curves which are stationary connected in Hilbert space is studied using triangular models of non-self-adjoint operator. The concept of evolutionary representability plays here an important role. It is proved that if one of two curves in Hilbert space is evolutionary representable and the curves are stationary connected, then another curve is evolutionary representable … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 17 May 2014 · 6,799 accessesView PDFCite
Research ArticleOpen accessIn the abstractBirds as a Tool for Island Habitat Conservation and ManagementPedro Rodrigues, Regina Tristao da CunhaProblem statement: The Azores is a archipelago of nine volcanic islands, situated in the middle of the North Atlantic Ocean. Oceanic islands are known hotspots of biodiversity and the Azores, although relatively young (0.3-13 MA), conform to this general pattern. The local avifauna amount to 37 birding species, with two endemic species and 11 endemic subspecies. With an estimated population … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 20 Jan 2012 · 8,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeographical Division Traceback for Distributed Denial of ServiceA. Viswanathan, V. P. Arunachalam, S. KarthikProblem statement: Distributed Denial of Service (DDoS) was a serious threat to the internet world that denies the legitimate users from being access the internet by blocking the service. Approach: In this study, we proposed a novel approach, Geographical Division Traceback (GDT) for efficient IP traceback and DDoS defense methodology. DDoS attack was one of the most serious and threatening … …Journal of Computer Science, Vol. 8, Issue 2 · 23 Nov 2011 · 7,129 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Face Recognition Technique Based on Modular LPCA ApproachMathu Soothana S. Kumar, Retna Swami, Muneeswaran KaruppiahProblem statement: A face identification algorithm based on modular localized variation by Eigen Subspace technique, also called modular localized principal component analysis, is presented in this study. Approach: The face imagery was partitioned into smaller sub-divisions from a predefined neighborhood and they were ultimately fused to acquire many sets of features. Since a few of the normal facial features of … …Journal of Computer Science, Vol. 7, Issue 12 · 22 Oct 2011 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study of Block Preconditioners for Incompressible Flow ProblemsJia LiuProblem statement: We consider the numerical solvers for the linearized Navier-Stokes problem. Both the Stokes problem and Oseen problems are considered. Approach: We used the Mark and Cell (MAC) discretization method to discretize the Navier-Stokes equations. We used preconditioned Krylov subspace methods to solve the resulting linear systems. Results: Numerical experimental results are performed to compare the different preconditioners. Conclusion: … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 14 Sep 2011 · 7,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeckle Suppression of Radar Images Using Normalized ConvolutionA. K. Helmy, G. S. El-TaweelProblem statement: Synthetic Aperture Radar (SAR) images are becoming more widely used in remote sensing applications. SAR uses microwave radiation to illuminate the earth's surface. The coherent microwave illumination, however, suffers from fading effects result in generating a multiplicative speckle noise that corrupts SAR images. Approach: Through this study, scheme to reduce speckles was proposed, it was designed to accomplish … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractFace Biometrics Based on Principal Component Analysis and Linear Discriminant AnalysisLih-Heng Chan, Sh-Hussain Salleh, Chee-Ming TingProblem statement: In facial biometrics, face features are used as the required human traits for automatic recognition. Feature extracted from face images are significant for face biometrics system performance. Approach: In this thesis, a framework of facial biometric was designed based on two subspace methods i.e., Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA). First, PCA is used for … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,664 accessesView PDFCite
