Research ArticleOpen accessPhrase in the titleQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Quantum Mechanical Study of Structural and Electronic Dilution Effects in Paramagnetic Chemical Exchange Saturation Transfer AgentsWhelton A. Miller III, Preston B. MooreWe present a computational study of the effect of chemical modifications of the meta and para substituents in the coordinating pendant arm of a modified 1,4,7,10-tetraazacyclododecane-N, N’, N’’, N’’’-tetraamide (DOTAM) ligand on the Chemical Exchange Saturation Transfer (CEST) signal. Magnetic Resonance Imaging (MRI) is currently one of the most widely used techniques available. MRI has led to a new class … …Journal of Organic and Biomolecular Simulations, Vol. 1, Issue 1 · 11 Dec 2013 · 28,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Optimal Medium in Which the ‘Celalettin-Field Quantum Observation Tunnel’ Operates: The Polarised Electron Cloud’s Emergence from the Laboratory Based Rubidium-87 to Helium-3; InvizicloudMetin Celalettin, Horace KingThis study discusses the previously mentioned Polarized Electron Cloud, its progression to ‘INVIZICLOUD’ as in the real word Rubidium-87 can only be used in the lab, whereas the molecule that is INVIZICLOUD© is made of is Helium-3 mixed with an atomic inert alkaline. It is the medium in which the ‘Celalettin-Field Quantum Observation Tunnel’ (CFQOT) operates. When a quantum qubit … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 21 Mar 2019 · 8,345 accessesView PDFCite
Research ArticleOpen accessIn the abstractExact Classical and Quantum Mechanics of a Generalized Singular Equation of Quadratic Liénard TypeLucas H. Koudahoun, Jean Akande, Damien K.K. Adjaï et al.Authors introduce a generalized singular differential equation of quadratic Liénard type for study of exact classical and quantum mechanical solutions. The equation is shown to exhibit periodic solutions and to include the linear harmonic oscillator equation and the Painlevé-Gambier XVII equation as special cases. It is also shown that the equation may exhibit discrete eigenstates as quantum behavior under Nikiforov-Uvarov … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 5 Jul 2018 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparing the Empirical and the Theoretical Probability Density of Return in which Variance Obeying Ornstein-Uhlenbeck Process at Indonesian Stock Exchange IDXDwi Satya Palupi, Eduardus Tandelilin, Arief Hermanto, Muhammad Farchani RosyidThe distribution of the probability density of a return index with stochastic volatility has been calculated. Here the stock index is assumed to follow geometric Brownian motion, while the variance is assumed to obey Ornstein-Uhlenbeck process as in Heston model. The distribution of the probability density of the return which is obtained by solving the Fokker-Planck equation of two dimensional … …American Journal of Applied Sciences, Vol. 14, Issue 9 · 17 May 2017 · 7,625 accessesView PDFCite
