Research ArticleOpen accessPhrase in the titleEnhancing P300 Component by Spectral Power Ratio Principal Components for a Single Trial Brain-Computer InterfaceS. Andrews, Ramaswamy Palaniappan, Andrew Teoh, Loo chu KiongHere we present a novel approach to detect P300 wave in single trial Visual Event Related Potential (VERP) signals using improved principal component analysis to enable a faster brain-computer interface (BCI) design. In the process, the principal components (PCs) are selected using novel methods, namely spectral power ratio (SPR) and sandwich spectral power ratio (SSPR). We set out to assess … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,881 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Pre-Processing and Classification Techniques for Single-Trial and Multi-Trial P300-Based Brain Computer InterfacesChanan S. Syan, Randy E.S. HarnarinesinghThe P300 component of Event Related Brain Potentials (ERP) is commonly used in Brain Computer Interfaces (BCI) to translate the intentions of an individual into commands for external devices. The P300 response, however, resides in a signal environment of high background noise. Consequently, the main problem in developing a P300-based BCI lies in identifying the P300 response in the presence … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,570 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Diversity in Merozoite Surface Protein.1 of Plasmodium falciparum in Highlands: Wamena Papua IndonesiaRosye Hefmi Rechnelty Tanjung, Yulius Sarungu, Meidy Johana Imbiri et al.Malaria is the first killer as well as endemic disease in highland, lowland and coastal areas of Papua. In 2016 there were 160 thousands cases noted and 80% of the cases were caused by Plasmodium falciparum. Total sample for this study were provided by a clinical trial conducted from May to June 2018 in the regional hospital of Puncak Jaya, … …American Journal of Infectious Diseases, Vol. 14, Issue 4 · 11 Jan 2019 · 7,753 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEWER DRUGS FOR VISCERAL LEISHMANIASIS: A REVIEWKrishna Pandey, Dharmendra Singh, Sanjiva Bimal et al.Visceral Leishmaniasis (VL) is one of the most neglected tropical diseases worldwide. The diagnosis and treatment of this disease is quite complex. Sodium Antimony Gluconate (SAG) which used to be a very effective treatment has now developed resistance and is potentially a cardio-toxic drug. Pentamidine has now been discarded because of adverse effect of diabetes mellitus. Amphotericin-B is an effective … …American Journal of Infectious Diseases, Vol. 10, Issue 2 · 5 May 2014 · 7,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Acute Toxicity and Neuropharmacological Activities of PM-52Wipawee Thukhum-Mee, Jintanaporn Wattanathorn, Supaporn MuchimapuraThe neuropsychological disorders are increasing their importance nowadays. Unfortunately, the therapeutic efficacy is still not in satisfaction level. Therefore, the novel agents that are effective, safe, cheap and easy to approach are in required. Therefore, we aimed to determine the neuropharmacological activities of PM52, the novel herbal supplement. We had developed the PM52, a novel product comprising of Cissampelas pariera … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 27 May 2013 · 7,351 accessesView PDFCite
Research ArticleOpen accessIn the abstractACUTE TOXICITY STUDY OF TOMATO POMACE EXTRACT IN RODENTSupaporn Muchimapura, Terdthai Tong-Un, Jintanaporn Wattanathorn et al.Tomato and tomato products are considered to be healthy food for the human diet. Although tomatoes have been widely studied for their phenolic content, less emphasize has been laid on toxicological effect of this plant. Thus, the purpose of the present study is to determine the acute toxicity effect of Lycopersicon esculentum, or commonly known as tomato, was administered orally … …OnLine Journal of Biological Sciences, Vol. 13, Issue 1 · 24 Feb 2013 · 7,683 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulberry Fruit Mitigates Alcohol Neurotoxicity and Memory Impairment Induced by Chronic Alcohol IntakeJintanaporn Wattanathorn, Nattaporn Phunchago, Supaporn Muchimapura et al.Problem statement: To date, the therapeutic strategy efficacy against memory impairment induced by alcohol intoxication is still limited. The novel therapeutic strategy which is easy to approach, less toxic and less cost is required. Based on the role of oxidative stress in memory impairment induced by alcohol, the neuroprotective effect of substance possessing antioxidant has gained much attention. Therefore, we … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 8 Feb 2012 · 9,328 accessesView PDFCite
Research ArticleOpen accessIn the abstractClinical Signs of Hairballs in Cats Fed a Diet Enriched with CelluloseA. C. Beynen, J. Middelkoop, D. H.J. SarisProblem statement: The intake of cellulose may delay gastric emptying and raise the intestinal transit rate. These effects could antagonize hairball formation. Thus, it was hypothesized that a diet enriched with a cellulose preparation (Arbocel BWW40®), forming a completely insoluble fiber network, would diminish the severity of clinical symptoms of hairballs in cats. Approach: In a double-blind, placebo-controlled trial with … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 8 Aug 2011 · 11,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractSummarizing Relational Data Using Semi-Supervised Genetic Algorithm-Based Clustering TechniquesRayner AlfredProblem statement: In solving a classification problem in relational data mining, traditional methods, for example, the C4.5 and its variants, usually require data transformations from datasets stored in multiple tables into a single table. Unfortunately, we may loss some information when we join tables with a high degree of one-to-many association. Therefore, data transformation becomes a tedious trial-and-error work and … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign Based on Intra-Class Correlation CoefficientsRobert Lew, Gheorghe DorosProblem statement: Reliability studies are concerned with the study of "consistency" or "repeatability" of measurements. Often times (but not always) the reliability coefficients are Intra-class Correlation Coefficients (ICC). Depending on the design or the conceptual intent of the study there are three types of intra-class correlation coefficients, termed intra-class correlation coefficients Case 1, 2 and 3, for measuring the reliability … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 18,541 accessesView PDFCite
