Research ArticleOpen accessIn the abstractcDNA Microarray Genome Image Processing Using Fixed Spot PositionBasim Alhadidi, Hussam Nawwaf Fakhouri, Omar S. AlMousaComplementary DNA (cDNA) microarray is one of the most recent and important technology for exploring the genome. cDNA microarray Image analysis aims to measure the intensity for each spot in the scanned image and this intensity represents the amount of a specific gene in the studied cell. This paper presents a new algorithm that achieves an automated way for applying … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 7,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractSplitting Technique Initialization in Local PCAAlok Sharma, Kuldip K. Paliwal, Godfrey C. OnwuboluThe local Principal Component Analysis (PCA) reduces linearly redundant components that may present in higher dimensional space. It deploys an initial guess technique which can be utilized when the distribution of a given multivariate data is known to the user. The problem in initialization arises when the distribution is not known. This study explores a technique that can be easily … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,725 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Partial Linearization of Byte Substitution Transformation of Rijndael-The AESY. Talwar, C. E.V. Madhavan, Navin RajpalRijndael-The AES[1-3] is 128-bit block cipher based on an elegant algebraic structure over F28. This cipher employs a simple approach to its substitution, permutation (SP) operations. We take a close look at its internals; the byte substitution transformation function is the only non-linear function in Rijndael - The AES. This transformation comprises of two steps operating on each byte. Here … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractWiFi Technology: Future Market Challenges and OpportunitiesAdel I. Al-AlawiComputer networks have played a major role in expanding the operational boundaries in organizations today. Until now traditional methods of networking, which involves computers, wired directly to a hub or switch are the norm. Recent advances in networking technology have made it possible for devices to communicate using various light and wave emitting technologies. WiFi is a perfect example of … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisk Assessment Study for Storage ExplosiveS. Saiful Azhar, M. Abdul Rahman, M. Saari et al.In Malaysia, there has been rapidly increasing usage in amount of explosives due to widely expansion in quarrying and mining industries. The explosives are usually stored in the storage where the safety precaution had given high attention. As the storage of large quantity of explosive can be hazardous to workers and nearby residents in the events of accidental denotation of … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,102 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-time Optimistic Concurrency Control based on Transaction Finish DegreeHan Qilong, Hao ZhongxiaoConcurrency control is one of the main issues in the studies of real-time database systems. Optimistic concurrency control algorithms have the attractive properties of being non-blocking and deadlock-free. However, they have the problems of late conflict detection and transaction restarts. Although the number of transaction restarts is reduced by dynamic adjustment of serialization order in real-time database systems, they are … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of the Chi-square Test to Determine Significance of Cumulative Antibiogram DataRocco J. Perla, James CarifioAn important function of a hospital’s Infectious Disease and Pharmacy programs is to review and compare the most recent antibiogram with that of the previous year to determine if significant changes in antibiotic susceptibility results are noted and to communicate this information and its consequences to the medical staff. However, there are currently no formal analytical (decision-making) models in use … …American Journal of Infectious Diseases, Vol. 1, Issue 4 · 31 Dec 2005 · 7,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation Between Circulating Early Endothelial Progenitors and CD4+CD25+ Regulatory T Cells: A Possible Cross-talk between Immunity and Angiogenesis?Shmuel Schwartzenberg, Adi Mor, Galia Luboshits et al.Regulatory T-cells (Treg) are a recently defined subset of CD4+ cells that can suppress inflammation and induce tolerance. Phenotypically, T-regs are characterized by a high level of expression of the IL-2 receptor alpha chain, CD25. Endothelial progenitor cells (EPCs) can transform into mature endothelial cells and promote vessel formation by inducing postnatal angiogenesis and vasculogenesis. Herein, we tested the hypothesis … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 6,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunomodulatory Treatment of Infertility in Men with Elevated Antisperm AntibodiesIvan Bubanovic, Slobodan Kojic, Stevo Najman, Zlatibor AndjelkovicPossible causes of subfertility or infertility in men are still poorly defined, but one important category may be elevated level of antisperm antibodies (ASA) caused by infective and/or autoimmune diseases, as well as injuries of male reproductive system. In this study, blood sera from 45 infertile men of different age with ASA positive ELISA test were examined for the serum … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 8,842 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Possibility of Cyclical Behavior in a Class of Dynamic ModelsAnjan MukherjiThe study investigates conditions under which endogenous cyclic behavior may be observed within the context of Predator-Prey (Lotka-Volterra) Models. The analysis also establishes conditions under which such behavior is non-existent and hence establishes conditions for global convergence to the interior equilibrium, whenever it exists. The results are then applied to two diverse sets of economic exercises and shows how the … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 9 Dec 2005 · 7,602 accessesView PDFCite
