Research ArticleOpen accessIn the abstractPacked Forest Chart ParserQi Haoliang, Li Sheng, Yang Muyun, Zhao TiejunPacked forest chart parser, like the traditional chart parsing algorithm, uses charts to store all the information produced while parsing to avoid redundant works. Its advantage over the traditional chart parser was the packed forest representation. The algorithm not only shares the non-terminal categories as what was done in the shared parse forest, but also shares the leftmost common elements. … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Study of Morphological Structure, Phase Structure and Molecular Structure of Collagen-PEO 600K Blends for Tissue Engineering ApplicationN. F. Mohd Nasir, M. G. Raha, N. A. Kadri et al.A new material which is collagen/ poly (ethylene oxide) (PEO) blend was developed to determine its possibility as a promising material for tissue scaffold. PEO with average molecular weight of 600,000 and collagen originated from calf skin were dispersed in 0.1 M acetic acid to prepare a concentration of 1 wt% for PEO and 0.15 wt% for collagen. The collagen-PEO600K … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 7,422 accessesView PDFCite
Research ArticleOpen accessIn the abstractWound Healing Process of Uncomplicated “Rusterholz” Ulcer, Following Treatment by Wooden Block and Hoofgel® in Bovine Hoof: Histopathological AspectsH. Azarabad, I. Nowrouzian, E. Soleymani et al.A broad and very detailed histopathological knowledge on cutaneous wound healing particularly in human skin is available, but few studies have documented this event in bovine claw sole ulcers. It seems the mechanism of wound healing might be basically the same followed by second intention healing which is finished in a period of time by formation of granulation tissue in … …American Journal of Animal and Veterinary Sciences, Vol. 1, Issue 2 · 31 Dec 2006 · 7,847 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Network on Chip resources allocation for QoS ManagementAbdelhamid HELALI, Adel SOUDANI, Jamila BHAR, Salem NASRIThe increasing complexity of integrated circuits and application requirements drive the research of new on-chip interconnection architectures. A network on chip draws on concepts inherited from distributed systems and computer networks subject areas to interconnect IP cores in a structured and scalable way. The main goal pursued is to achieve superior bandwidth when compared to conventional on-chip bus architectures. The … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of an IP Library for the Synthesis of Image Compression SystemsChokri Souani, Ihsen Gazzah, Kamel BesbesTo design a hardware system we may use generated Intellectual Property (IP) cores from a library with optimized parameters. The IP parameters are area minimization, memory use optimization and speed acceleration. The designed system depends on such IP parameters. In this paper, we propose the design of an IP library optimized with different constraints. The created IPs may be used … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Backpropagation Neural Network for Computer Network SecurityKhalil ShihabIn this paper, an efficient and scalable technique for computer network security is presented. On one hand, the decryption scheme and the public key creation used in this work are based on a multi-layer neural network that is trained by backpropagation learning algorithm. On the other hand, the encryption scheme and the private key creation process are based on Boolean … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 19,535 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Attacks on RSA CryptosystemImad K. Salah, Abdullah Darwish, Saleh OqeiliIn this paper some of the most common attacks against Rivest, Shamir, and Adleman (RSA) cryptosystem are presented. We describe the integer factoring attacks, attacks on the underlying mathematical function, as well as attacks that exploit details in implementations of the algorithm. Algorithms for each type of attacks are developed and analyzed by their complexity, memory requirements and area of … …Journal of Computer Science, Vol. 2, Issue 8 · 31 Aug 2006 · 8,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractNeuropsychological Dysfunction among HIV Infected Drug AbusersRamani S. Durvasula, Charles H. HinkinHuman immunodeficiency virus (HIV) has been documented to cause direct and indirect central nervous system dysfunction that can be observed as a progressive decline in neuropsychological functioning in a large proportion of persons with HIV and AIDS. Neuropsychological decline in individuals with HIV is characterized by cognitive and motor slowing, attentional deficits, executive dysfunction and memory impairment (characterized by intact … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeroin-Induces Differential Protein Expression by Normal Human Astrocytes (NHA)Jessica L. Reynolds, Supriya D. Mahajan, Donald Sykes, Madhavan P.N. NairHeroin use is postulated to act as a cofactor in the neuropathogenesis of human immunodeficiency virus (HIV-1) infection. Astrocytes, integral components of the CNS, are reported to be susceptible to HIV-1 infection. Upon activation, astrocytes release a number of immunoregulatory products or modulate the expression of a number of proteins that foster the immunopathogenesis of HIV-1 infection. However, the role … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,261 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Basis of Magnetic Resonance Spectroscopy and its Application to Central Nervous System DiseasesNicolás Fayed, Salvador Olmos, Humberto Morales, Pedro J. ModregoMagnetic Resonance Spectroscopy is based on the chemical shift property of the atom nuclei when a magnetic field is applied. This technique offers invaluable information about living tissues with special contribution to the diagnosis and prognosis of the central nervous system diseases. Concentration of several metabolites can be assessed in a reproducible manner by means of modern clinical scanners.
