Research ArticleOpen accessIn the abstractInverse Correlations for Multiple Time Series and Gaussian Random Fields and Measures of Their Linear DeterminismR.J. Bhansali, L. IppolitiFor a discrete-time vector linear stationary process, {X(t)}, admitting forward and backward autoregressive representations, the variance matrix of an optimal linear interpolator of X(t), based on a knowledge of {X(t-j), j≠0}, is known to be given by Ri(0)-1 where Ri(0) denotes the inverse variance of the process. Let A=Is-1Ri(0)ˉ1R(0)ˉ1, where R(0) denotes the variance matrix of {X(t)} and Is an … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of a QoS-Aware Mechanism for Polling-Based High-Speed Network InterfacesSalman Al-Qahtani, Tarek Helmy, Khaled SalahThe explosive growth of the high-speed multimedia networks and the widespread use of web-based related applications place new demands on the network servers. The network end systems such as PC-Router, network server and host connected to high speed links must satisfy QoS requirements for multimedia traffics such as delay and loss ratio. Most works on operating systems support for high-speed … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,565 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 · 6,902 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 · 8,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractIrrationality in the Neoclassical Definition of RationalitySteve KeenIn this study we are not arguing that competition as it actually occurs in practice is not socially beneficial. Our criticism is directed instead at the false belief that rational profit-maximizing behavior and competition as defined by neoclassical economic theory will lead to a welfare-maximizing outcome-again, as defined by neoclassical theory. …American Journal of Applied Sciences, Vol. 2, Issue 13 · 18 Dec 2005 · 8,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroduction to the Besov Spaces and Triebel-Lizorkin Spaces for Hermite and Laguerre expansions and some applicationsA. Iris, P. LopezWe introduced new definitions of Besov spaces and Triebel-Lizorkin spaces associated with multidimensional Hermite expansions and multidimensional Laguerre expansions. We showed that the set of p-integrable functions is a Triebel-Lizorkin space with respect to the Gaussian measure and similarly, with respect to the probabilistic Gamma measure. Also, we showed that the Gaussian Sobolev spaces and Laguerre Sobolev spaces are Triebel-Lizorkin … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Reliable Efficient Multicasting Protocol for Mobile Ad Hoc NetworksK. Baskaran, A. Ebenezer Jeyakumar, V. Sumathy, J. Lakshmana PerumalThe Adaptive Reliable Multicast Protocol (ARM) with intermediate node support is introduced to guarantee message delivery to all multicast receivers in mobile ad hoc environment. ARM distributes multicast message cache and retransmission tasks among intermediate nodes to offer a scalable reliable multicasting. Due to limited memory and node’s mobility, ARM defines intermediate node as all nodes which overhear multicast messages. … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards a Scalable File System on Computer Clusters Using DeclusteringVu Anh Nguyen, Samuel Pierre, Dougoukolo KonaréThis study addresses the scalability issues involving file systems as critical components of computer clusters, especially for commercial applications. Given that wide striping is an effective means of achieving scalability as it warrants good load balancing and allows node cooperation, we choose to implement a new data distribution scheme in order to achieve the scalability of computer clusters. We suggest … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoluble Tumor Necrosis Factor Receptor Type I and Dranulysin as Immunological Markers in Congestive Heart FailureSimone de Lima e Silva Deo, Maria Do Carmo Valente De Crasto, Alda Maria Da-Cruz et al.Previous studies have shown that circulating levels of cytokines are increased in patients with congestive heart failure (CHF), resulting in myocardial depression. In this work, we have determined serum levels of TNF-α and IFN-γ by ELISA, detected sTNFR-I by dot ELISA, as well as TNFα, IL-6, IL-10 and granulysin mRNA in unstimulated peripheral blood mononuclear cells (PBMC) by RT-PCR in … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractCodesign Methodology of Real-time Embedded Controllers for Electromechanical SystemsSlim Ben Saoud, Andreas Gerstlauer, Daniel D. GajskiUnder increasing time-to-market pressures in the electric drives industries, the development time of new algorithms and new control systems including their debugging time must be minimized. This requirement can be satisfied only by using a well-defined system-level design methodology and by reducing the migration time between the algorithm development language and the hardware specification language. In this study, we propose … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,444 accessesView PDFCite
