Research ArticleOpen accessIn the abstractSocio-Demographic Determinants of Adult Tuberculosis: A Matched Case-Control Study in BangladeshSamira Dishti Irfan, Mohammad Omar Faruque, Mahabub Ul Islam et al.Tuberculosis (TB) is a multi-systemic infectious disease that has evoked a substantial disease burden in developing countries, including Bangladesh. The aim of this study is to determine the socio-demographic risk factors for adult tuberculosis. A matched case-control study was conducted with 178 cases and 179 controls from a selected TB hospital in Dhaka. Data was collected via face-to-face interview using … …American Journal of Infectious Diseases, Vol. 13, Issue 3 · 6 Nov 2017 · 10,452 accessesView PDFCite
Research ArticleOpen accessIn the abstractStroke Associated with Infective Endocarditis. Frequency and Prognostic ImplicationsJuan José Mengual Chirife, Manuel Gómez-Choco, Ester MoralStroke can be one of the most severe complications of Infective Endocarditis (IE) and it happens in 14% of patients with IE. Therefore, we aimed to review stroke frequency in patients diagnosed with IE in our hospital from 2010 to 2020. We defined it as IE-Associated Stroke (IEAS) when the stroke happened one month before or after IE's diagnosis. Sixty-six … …American Journal of Infectious Diseases, Vol. 17, Issue 4 · 7 Sep 2021 · 6,860 accessesView PDFCite
Research ArticleOpen accessIn the abstractKnowledge, Training Status and Willingness to Implement Cardiopulmonary Resuscitation of Medical University Students in Chongqing, ChinaHuixian Zhou, Chuan Pu, Feng Chen et al.Timely bystander Cardiopulmonary Resuscitation (CPR) is key to improving survival from out-of-hospital cardiac arrest. Medical university students are potential bystander CPR providers. This study aimed to identify the current level of CPR knowledge, the present status of training and factors affecting the willingness to perform CPR among medical university students in Chongqing, China. Random sampling method was used and a … …Journal of Social Sciences, Vol. 17, Issue 1 · 5 Apr 2021 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiotic and Abiotic Factors of Sperm nDNA Fragmentation in Farm AnimalsBaylar Iolchiev, Natalya Volkova, Pavel Klenovitskiy et al.Infertility and subfertility are among the global challenges of our time. Fertility in livestock farming is not only biologically important, it is also economically important. The aim of this study was to study the effect of these factors on sperm chromatin nucleus and to assess the impact of the fragmentation index degree on bull reproductive performance. The influence of abiotic … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 11 Mar 2021 · 6,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Human Emotions via Univariate and Multivarite Multiscale EntropyKawser AhammedThis work analyzes the emotions of human in terms of complexity. This analysis is achieved by applying both univariate and multivariate multiscale entropy methods on a multimodal dataset. Most of the contemporary human-computer interaction systems are unable to identify human affective states. So, the benefit of analyzing human emotions is to fill this gap by detecting human affective states. The … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 23 Jul 2015 · 8,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Ibuprofen and Paracetamol in Binary Mixture Using Chemometric-Assisted Spectrophotometric MethodsWafaa S. HassanThree methods are presented for simultaneous determination of ibuprofen and paracetamol without previous separation. The first method depends on first derivative UV spectrophotometry, with zero-crossing measurement. The first derivative amplitudes at 230 and 290 nm were selected for the assay of ibuprofen and paracetamol, respectively. The second method depends on first derivative of the ratio-spectra by measurements of the amplitudes … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractExistence and Uniqueness Conditions for the Maximum Likelihood Solution In Regression Models For Correlated Bernoulli Random VariablesDavid Todem, KyungMann KimWe give sufficient and necessary conditions for the existence of the maximum likelihood estimate in a class of multivariate regression models for correlated Bernoulli random variables. The models use the concept of threshold crossing technique of an underlying multivariate latent variable with univariate components formulated as a linear regression model. However, in place of their Gaussian assumptions, any specified distribution … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric-Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV MethodsHesham Salem, Ola M. AbdallahFour methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amplitudes at 250.1 nm … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 8,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mean-Variance Portfolio Optimal Under Utility PricingHürlimann WernerAn expected utility model of asset choice, which takes into account asset pricing, is considered. The obtained portfolio selection problem under utility pricing is solved under several assumptions including quadratic utility, exponential utility and multivariate symmetric elliptical returns. The obtained unique solution, called optimal utility portfolio, is shown mean-variance efficient in the classical sense. Various questions, including conditions for complete … …Journal of Mathematics and Statistics, Vol. 2, Issue 4 · 31 Dec 2006 · 6,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractSplitting Technique Initialization in Local PCAAlok Sharma, Kuldip K. Paliwal, Godfrey C. OnwuboluThe local Principal Component Analysis (PCA) reduces linearly redundant components that may present in higher dimensional space. It deploys an initial guess technique which can be utilized when the distribution of a given multivariate data is known to the user. The problem in initialization arises when the distribution is not known. This study explores a technique that can be easily … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,719 accessesView PDFCite
