Research ArticleOpen accessIn the abstractA Suggested Nonparametric Bivariate Logistic Density Estimator with Application on the Productivity of Egyptian Wheat during 2019/2020Samah M. Abo-El-HadidIn this study, the nonparametric standard logistic density estimator, introduced by Abo-El-Hadid (2018), is extended to the bivariate case. The multiplicative standard logistic distribution is used as a kernel function to derive the bivariate kernel estimator. The statistical properties of the resulting estimator are studied, which are: The asymptotic bias, variance, Mean Squared Error (MSE) and Integrated Mean Squared Error … …Journal of Mathematics and Statistics, Vol. 17, Issue 1 · 27 May 2021 · 6,711 accessesView PDFCite
Literature ReviewOpen accessIn the abstractDevelopment of Azithromycin Resistance in Streptococcus pneumoniae in the Setting of Trachoma Mass Drug Administration: A Systematic ReviewNazia Khan, Barbara Lachana Onen, Robin Hilder, Robin BaileyTrachoma is a blinding eye disease caused by the bacterium Chlamydia trachomatis. The current global elimination of trachoma initiative includes the use of mass drug distribution of azithromycin in areas where the prevalence of follicular trachoma is >10% in children aged 1-9 years. This study aims to investigate the high quality evidence of whether mass drug administration for trachoma causes … …American Journal of Infectious Diseases, Vol. 16, Issue 3 · 24 Jul 2020 · 7,596 accessesView PDFCite
Literature ReviewOpen accessIn the abstractBasics of Photocatalysis and Different Strategy for Enhancing the Photocatalytic EfficiencyYuvaraj M. Hunge, Anuja A. Yadav, Babasaheb M. MohiteThis review reports on the basic mechanism of photocatalysis and different ways of enhancing the photocatalytic efficiency. It further examines enhancement of the photocatalytic property using the different combinations of semiconductor oxides (TiO2, ZnO, stratified WO3/TiO2, WO3/ZnO). TiO2, ZnO semiconductors have been widely used from the recent few decades in the photocatalytic degradation process, but the main drawback of these … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 21 May 2020 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Extended Semi-Parametric Accelerated Failure Time Cure Model for Partial Cure Information KnownYu Wu, Yong Lin, Shou-En Lu et al.Cure model is a useful model for analyzing failure time data when there is evidence of long-term survivors. In traditional cure models, it is assumed that the cured or uncured status in the censored set cannot be distinguished. However, in many occasions, data of some diagnostic procedures, with some sensitivity and specificity, may have provided partial information about the cured … …Current Research in Biostatistics, Vol. 8, Issue 1 · 11 Dec 2018 · 7,618 accessesView PDFCite
Research ArticleOpen accessIn the abstractContextual Analyses of Attitudes toward Persons with Physical DisabilitiesChristopher M. Amissah, Christopher K. Gadosey, Kingsley Nyarko, Collins B. AgyemangSocial desirability bias associated with attitudinal research can be minimized through contextual analyses. This study assessed attitudes toward persons with physical disabilities in three social contexts: Dating, marriage and workplace. It also examined the effects of social contact on attitudes. Using a cross-sectional survey, 202 Ghanaians were purposively sampled to respond to the Disability Social Relations Generalized Disability (DSRGD) scale. … …Current Research in Psychology, Vol. 7, Issue 2 · 8 Jan 2018 · 16,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractObservational Study of Wind Shear in Northeastern BrazilFernando R. Martins, André R. Gonçalves, Enio B. PereiraThe wind energy share is growing fast in Brazil and a better understanding of wind speed vertical profiles is essential for accurate power density estimates. The wind shear is highly variable in space and time, being influenced by surface layer stability. Studies concerning wind vertical profiles may have a significant contribution to the Brazilian energy sector. However, wind observational data … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 12 Mar 2016 · 8,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE ERROR REGISTRATION TECHNIQUE FOR MANEUVERING RADAR NETWORKLiu Yu, Wang Haipeng, Xiong Wei, He YouThis study studies are error registration algorithm for the maneuvering radar network, which is one of the difficult problems of multi-sensor registration. When the maneuvering radar has no orientation bias, measurement equations of both attitude bias and measurement bias can be established by using the common targets observed by different radars. Based on the equations, the real-time estimation of both … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,581 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization and Modification of Point Sampling and Line Sampling in the Forestry SurveyDifei ZhangProblem statement: In the practice of conventional point sampling and line sampling methods in the forestry survey, we often encounter problems such as boundary and hole problems. These problems could introduce bias in the results of forest sampling. Proper modifications are needed. Approach: This study developed novel probability computation approaches in the utilization and modification of horizontal point sampling and … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 7,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Direct Current and Temperature Stresses of Low-Voltage ZnO Based Varistor CeramicsM. G.M. Sabri, B. Z. Azmi, Zahid Rizwan et al.Problem statement: The stresses to humidity, DC and AC bias, multiple impulse voltages and high temperatures are known to affect the varistor performance and it is also interesting to know the effect of both DC bias and temperature stresses at the same time. Approach: Here, the simultaneous DC and temperature stresses degradation was investigated to see the changes of nonlinear … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,379 accessesView PDFCite
Review ArticleOpen accessIn the abstract"Ebola Ça Suffit!" is not enough to Prove Efficacy of an Ebola VaccineDavid R CroweA recently published Ebola vaccine trial claimed an almost perfect result with no cases of Ebola after the vaccine had time to take effect - a vaccine efficacy of 100%. This article is a detailed review of the information published about the trial and, particularly, this claim. The trial design was sub-optimal because randomization was only partial (and one treatment … …American Journal of Immunology, Vol. 13, Issue 3 · 8 Jul 2017 · 17,825 accessesView PDFCite
