On phi-Mori rings
(University of Houston, 2006)
A commutative ring R is said to be a phi-ring if its nilradical Nil(R) is both prime and comparable with each principal ideal. The name is derived from the natural map phi from the total quotient ring T(R) to R localized ...
Few-cycle laser driven reaction nanoscopy on aerosolized silica nanoparticles
(Springer Nature, 2019)
Nanoparticles offer unique properties as photocatalysts with large surface areas. Under irradiation with light, the associated near-fields can induce, enhance, and control molecular adsorbate reactions on the nanoscale. ...
Green Synthesis of Encapsulated Copper Nanoparticles Using a Hydroalcoholic Extract of Moringa oleifera Leaves and Assessment of Their Antioxidant and Antimicrobial Activities
(MDPI, 2020)
The synthesis of metal nanoparticles using plant extracts is a very promising method in green synthesis. The medicinal value of Moringa oleifera leaves and the antimicrobial activity of metallic copper were combined in the ...
B − L violating interactions in supersymmetric SO(10) models
(IOP Science, 2019)
An analysis is given of B − L violating interactions in SO(10) arising from the integration of $10+\bar{10}$ of SU(5) of heavy Higgs. The analysis is done within the well defined missing partner model where the doublet-triplet ...
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 ...
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 ...
Mechanical perturbation control of cardiac alternans
(American Physical Society, 2018)
Cardiac alternans is a disturbance in heart rhythm that is linked to the onset of lethal cardiac arrhythmias. Mechanical perturbation control has been recently used to suppress alternans in cardiac tissue of relevant size. ...
Antiamoebic activity of plant‑based natural products and their conjugated silver nanoparticles against Acanthamoeba castellanii (ATCC 50492)
(Springer, 2020)
Acanthamoeba spp. are the causative agent of Acanthamoeba keratitis and granulomatous amoebic encephalitis (GAE). The current options to treat Acanthamoeba infections have limited success. Silver nanoparticles show ...
Option convergence rate with geometric random walks approximations
(Taylor & Frances Online, 2016)
We describe a broad setting under which, for European options, if the underlying asset form a geometric random walk then, the error with respect to the Black–Scholes model converges to zero at a speed of 1/𝑛 for continuous ...
