Biophysical model of coral population connectivity in the Arabian/Persian Gulf
(Elsevier, 2020)The coral reef ecosystems of the Arabian/Persian Gulf (the Gulf ) are facing profound pressure from climate change (extreme temperatures) and anthropogenic (land-use and population-related) stressors. Increasing degradation ... -
The Boyle–Romberg trinomial tree, a highly efficient method for double barrier option pricing
(MDPI, 2024-03-24)Oscillations in option price convergence have long been a problematic aspect of tree methods, inhibiting the use of repeated Richardson extrapolation that could otherwise greatly accelerate convergence, a feature integral ... -
Can High-Order Convergence of European Option Prices be Achieved with Common CRR-Type Binomial Trees?
(Springer, 2015)Considering European call options, we prove that CRR-type binomial trees systematically underprice the value of these options, when the spot price is not near the money. However, we show that, with a volatility premium to ... -
Can the Full Spectrum Fitting Technique correctly detect Age Spreads in Young Star Clusters?
(IOP Science, 2019)Integrated spectra of star clusters have proven to be accurate tools for obtaining age, metallicity and reddening of extragalactic clusters for which resolved data is not available. In this work we investigate the possibility ... -
Chemical disinfectants of COVID-19: an overview
(IWA Publishing, 2020-07)The outbreak of coronavirus (COVID-19) has led to a broad use of chemical disinfectants in order to sterilize public spaces and prevent contamination. This paper surveys the chemicals that are effective in deactivating the ... -
Climbing Grammar Mountain: An Interactive Learning Experience
(United States Department of State, 2005)This article describes a grammar game that is an enjoyable way for students to correct sentences. In Climbing Grammar Mountain, best suited for secondary and university students, learners compete in teams to "climb" a game ... -
Coexistence and extinction in a competitive exclusion Leslie/Gower model with harvesting and stocking
(Taylor & Francis Online, 2009)The principle of competitive exclusion states that when the competition between species is sufficiently strong, only the dominant species survives. In this paper, we examine the strategies of using stocking and harvesting ... -
Complex anaphora with this: variation between three written argumentative genres
(Edinburgh University Press, 2017)The concept of complex anaphora - ‘nominal expressions referring to propositionally structured referents’ (Consten et al., 2007) - makes a useful distinction between a text-structuring function, one important to argumentative ... -
Compound distributions for financial returns
(PLOS, 2020)In this paper, we propose six Student’s t based compound distributions where the scale parameter is randomized using functional forms of the half normal, Fréchet, Lomax, Burr III, inverse gamma and generalized gamma ... -
Control of cardiac alternans by mechanical and electrical feedback
(American Physical Society, 2014)A persistent alternation in the cardiac action potential duration has been linked to the onset of ventricular arrhythmia, which may lead to sudden cardiac death. A coupling between these cardiac alternans and the intracellular ... -
Convergence rate of regime-switching trees
(Elseveir, 2016)Considering a general class of regime-switching geometric random walks and a broad class of piecewise twice differentiable payoff functions, we show that convergence of option prices occurs at a speed of order 𝒪 (𝑛-ᵝ), ... -
Convergence rate of the binomial tree scheme for continuously paying options
(Université du Québec à Montréal, 2012)Continuously Paying Options (CPOs) form a very natural class of derivatives for hedging risks coming from adverse movements of a continuously traded asset. We study the rate of convergence of CPOs evaluated under the ... -
Corrections to Yukawa couplings from higher dimensional operators in a natural SUSY SO(10) and HL-LHC implications
(Springer, 2021-01-11)We consider a class of unified models based on the gauge group SO(10) which with appropriate choice of Higgs representations generate in a natural way a pair of light Higgs doublets needed to accomplish electroweak symmetry ... -
Croft’s cycle in Arabic: The negative existential cycle in a single language
(De Gruyter, 2020-05)The negative existential cycle has been shown to be operative in several language families. Here it is shown that it also operates within a single language. It happens that the existential fī that has been adduced as an ... -
Cyclic Sequential Removal of Alizarin Red S Dye and Cr(VI) Ions Using Wool as a Low-Cost Adsorbent
(MDPI, 2020)Alizarin red S (ARS) removal from wastewater using sheep wool as adsorbent was investigated. The influence of contact time, pH, adsorbent dosage, initial ARS concentration and temperature was studied. Optimum values were: ... -
The Dehortative in the Spoken Arabics of the Eastern Mediterranean
(University of Bucharest, 2016)A few authors mention a hortative mood in Arabic, formed in a variety of manners, usually involving a pre-verbal element and an unmarked imperfective verb, sometimes thought of as the jussive or subjunctive. Not an imperative, ... -
A Density Functional Theory Study of the Cu⁺ · O₂ and Cu⁺ · N₂ Adducts
(De Gruyter, 2011)The geometries and harmonic vibration frequencies of the Cu⁺·O₂ and Cu⁺ ·N₂ are determined by various density functional theory (DFT) methods employing different basis sets. The potential energy surfaces (PES) are examined. ... -
Detailed Chemical Abundances of Star Clusters in the Large Magellanic Cloud
(American Astronomical Society, 2022)We derive the first detailed chemical abundances of three star clusters in the Large Magellanic Cloud (LMC), NGC 1831 (436 ± 22 Myr), NGC 1856 (350 ± 18 Myr), and [SL63]268 (1230 ± 62 Myr) using integrated-light spectroscopic ... -
Development and Characterization of Novel Composite and Flexible Electrode Based on Titanium Dioxide
(IEEE, 2020-06-11)Flexible implantable bioelectrodes have the potential to advance neural sensing and muscle stimulation, especially in peripheral nerve injuries. In such cases, the application of electrical stimulation to muscles prevents ... -
Development of Liposome-Based Immunoassay for the Detection of Cardiac Troponin I
(MDPI, 2021)Cardiovascular diseases (CVDs) are one of the foremost causes of mortality in intensive care units worldwide. The development of a rapid method to quantify cardiac troponin I (cTnI)—the goldstandard biomarker of myocardial ...
