Research ArticleOpen accessIn the abstractPerformance Evaluation of Multi-Pulse Based Code Excited Linear Predictive Speech Coder with Bitrate Scalable Tool over Additive White Gaussian Noise and Rayleigh Fading ChannelsSuphattharachai ChomphanProblem statement: In the modern speech communication technology, the speech coding with bitrate scalability was needed. However, various types of noises in the communication channels cause damages in the transmitted information especially speech data. Tonal-language speech was also affected by this situation. Approach: Based on the high pitch delay resolution technique, the MPCELP speech coding was proposed over the environment … …Journal of Computer Science, Vol. 6, Issue 12 · 6 Nov 2010 · 7,085 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA 30 Year Old Man with Fever and Indolent Soft Tissue MassesWissam Zaeeter, Ashwin Jathavedam, Rosalyn StahlAbstract: Problem statement: Multifocal Skeletal Tuberculosis (MSTB) is a rare presentation of skeletal tuberculosis. The indolent nature of this condition often leads to delayed or missed diagnosis, sometimes with devastating consequences for the patient. In order to provide meaningful clinical information and to highlight pitfalls in diagnosis of MFST, we present a case of MSTB. A review of this condition … …American Journal of Infectious Diseases, Vol. 6, Issue 3 · 30 Sep 2010 · 7,713 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStroke Motion Learning for a Humanoid Robotic Ping-Pong Player Using a Novel Motion Capture SystemC. H. Lai, T.I. James TsayProblem statement: Human ping-pong players determine the stroke trajectory according to their experience before the ball enters their court. However, to enable a humanoid robot to select the appropriate stroke motion based on skills learned from 3D motion, important patterns must be generated to simplify the complex 3D motion. Approach: This study developed an effective strategy for teaching ping-pong skills … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,382 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of W7, a Specific Calmodulin Inhibitor, to the Antinociceptive Effects of Morphine in Adrenalectomized RatsGholamreza Sepehri, Kayvan Yaghoobi, Vahid Sheibani et al.Problem statement: This study was performed to evaluate the effect of W7 (specific calmodulin inhibitor) on morphine induced analgesia in Adrenalectomized (ADX) rats by tail-flick test. Approach: Tolerance to morphine was induced in male Wistar rats by daily injections of morphine (15 mg kg-1, i.p) for 8 days. Adrenalectomy was performed under general anesthesia with intraperitoneal (i.p) injection of ketamine … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 7,649 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnt Diversity in a Sugarcane Culture without the Use of Straw Burning in Southeast, Sao Paulo, BrazilDébora Rodrigues De Souza, Erich Stingel, Luiz Carlos de Almeida et al.Problem statement: One of the current requirements of agroecosystem management is the maintenance of biodiversity. Manual sugarcane harvesting with the previous burning of straw has been gradually replaced by mechanical harvesting in Brazil. However, the diversity of Formicidae, which can be a natural pest controller, has not been studied in this new system yet. Approach: This study was carried out … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,646 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProsody Modification of Standard Arabic Speech Using Combining Synchronous Overlap and Add With Fixed-Synthesis Algorithm and Multi Level Discrete Wavelet TransformYkhlef Faycal, Bensebti Mesaoud, Bendaouia LotfiProblem statement: The objective of prosody modification is to change the amplitude, duration and pitch (F0) of speech segments without altering their spectral envelop. Applications are numerous, including, Text-To-Speech synthesis, transformation of voice characteristics and foreign language learning. Several approaches have been developed in the literature to achieve this goal. The main restrictions of these latter are in the modification … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,836 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Computer Simulation Model for Automated Quantification of Luteinizing Hormone SecretionAyman Al-Nsour, Hamza A. Ali, Buthynna Al-Dulaimi, Wisam H. Al-SewadiProblem statement: An automated software package is developed for quantifying Luteinizing Hormone (LH) release from pituitary gonadotropes in response to short pulses of Gonadotropin-Releasing Hormone (GnRH). Approach: These computer programs were designed to accommodate the release mechanism that consists of three stages, namely; (1) Production of different concentrations of effectors (such as receptor-hormone binds, G protein interactions, inositol 1,4,5-trisphosphate IP3), … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 6,938 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTen Common Misunderstandings, Misconceptions, Persistent Myths and Urban Legends about Likert Scales and Likert Response Formats and their AntidotesJames Carifio, Rocco J. PerlaA recent article by Jamieson in Medical Education outlined some of the (alleged) abuses of "Likert scales" with suggestions about how researchers can overcome some of the (alleged) methodological pitfalls and limitations[1]. However, many of the ideas advanced in the Jamison article, as well as a great many of articles it cited, and similar recent articles in medical, health, psychology, … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 53,786 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNeuroendocrine Abnormalities in Drug Abusers and HIV-Infected Individuals: Cortisol Response to Cold Pressor ChallengeMahendra Kumar, Drenna Waldrop-Valverde, Adarsh M. Kumar et al.Although endocrine abnormalities have been reported in HIV-1 infection, the role of risk factors is not understood. Injecting drug use (IDU) is an important risk factor for contracting HIV-infection and studies suggest that substance use may also be associated with endocrine dysfunction. In order to investigate hypothalamic pituitary adrenal (HPA) axis activity in this population, this study investigated cortisol response … …American Journal of Infectious Diseases, Vol. 2, Issue 3 · 30 Sep 2006 · 6,594 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGonadal and Adrenal Abnormalities in Drug Users: Cause or Consequence of Drug Use Behavior and Poor Health OutcomesTodd T. Brown, Amy B. Wisniewski, Adrian S. DobsOpiates and cocaine both have effects on adrenal and gonadal function. Opiates suppress the hypothalamic-pituitary adrenal (HPA) axis, whereas cocaine leads to HPA activation. Opiates also cause gonadal dysfunction in both men and women. During withdrawal from opiates and cocaine, the HPA axis is activated which may reinforce relapse behavior. This review describes these hormonal effects and explores the potential … …American Journal of Infectious Diseases, Vol. 2, Issue 3 · 30 Sep 2006 · 7,049 accessesView PDF Cite
