A Global Attractor in Some Discrete Contest Competition Models with Delay under the Effect of Periodic Stocking
(Hindawi, 2013)
We consider discrete models of the form 𝒳ₙ₊₁= 𝒳ₙ𝒇(𝒳ₙ₋₁) + 𝒉ₙ , where 𝒉ₙ is a nonnegative 𝒑-periodic sequence representing stocking in the population, and investigate their dynamics. Under certain conditions on the ...
The solution of a recursive sequence arising from a combinatorial problem in botanical epidemiology
(Taylor & Francis, 2013)
One of the central problems in botanical epidemiology is whether disease spreads within crops in a regular pattern or follows a random process. In this paper, we consider a row of n plants in which m are infected. We then ...
The dynamics of some discrete models with delay under the effect of constant yield harvesting
(Elsevier, 2013)
In this paper, we study the dynamics of population models of the form xn+1 = xnf(xn−1) under the effect of constant yield harvesting. Results concerning stability, boundedness, persistence and oscillations of solutions are ...
Novel algorithms for accurate DNA base-calling
(Scientific Research Publishing, 2013)
The ability to decipher the genetic code of different species would lead to significant future scientific achievements in important areas, including medicine and agriculture. The importance of DNA sequencing necessitated ...
Evaluation of the interaction potential of synthetic ethylene glycol compounds with nuclear Factor κB
(PKP, 2013)
In the last three decades, nuclear factor κB (NF-κB) has been the focus of many researchers who are interested in understanding the various molecular mechanisms involved in inflammatory diseases and cancer. Interference ...
On weakly 2-absorbing ideals of commutative rings
(University of Houston, 2013)
Let R be a commutative ring with identity 1 not equal to 0. In this paper, we introduce the concept of a weakly 2-absorbing ideal. A proper ideal I of R is called a weakly 2-absorbing ideal of R if whenever abc is not equal ...
A European option general first-order error formula
(Cambridge, 2013)
We study the value of European security derivatives in the Black-Scholes model, when the underlying asset 𝛏 is approximated by random walks 𝛏(𝑛). We obtain an explicit error formula, up to a term of order 𝒪(𝑛⁻³/² ), ...
Faculty use of the course management system (CMS) iLearn at the American University of Sharjah
(Zayed University Press, 2013)
That course management systems (CMS) are relevant to higher education is beyond question. Tertiary institutions invest significant resources in developing CMS and promoting their use by faculty members. Considerable research ...
Utilizing active learning strategies to enhance learning in first year university chemistry courses
(Zayed University Press, 2013)
Teaching chemistry to non-science majors can be a challenge in higher education owing to students’ perceptions of the subject’s difficulty, and of its usefulness. In order to address these challenges, the authors applied ...
