Existence and stability of periodic orbits of periodic difference equations with delays
(World Scientific Publishing, 2008)
In this paper, we investigate the existence and stability of periodic orbits of the p-periodic difference equation with delays xₙ = f(n - 1, xₙ₋ₖ). We show that the periodic orbits of this equation depend on the periodic ...
Periodic Orbits in Periodic Discrete Dynamics
(Elsevier, 2008)
We study the combinatorial structure of periodic orbits of nonautonomous difference equations 𝒳ₙ₊₁ = 𝒇ₙ(𝒳ₙ) in a periodically fluctuating environment. We define the Ӷ-set to be the set of minimal periods that are not ...
The trans-10, cis-12 isomer of conjugated linoleic acid decreases adiponectin assembly by PPARγ-dependent and PPARγ-independent mechanisms
(Elsevier, 2008)
The adipocyte-derived secretory protein adiponectin functions as an insulin-sensitizing agent. In plasma, adiponectin exists as low, medium, and high molecular weight oligomers. Treatment with trans-10, cis-12 conjugated ...
Some finiteness conditions on the set of overrings of a phi-ring
(University of Houston, 2008)
Let H = {R | R is a commutative ring and Nil(R) is a divided prime ideal of R}. For a ring R in H with total quotient ring T(R), Let phi be the natural ring homomorphism from T(R) into R_Nil(R). An integral domain R is ...
Exercisability Randomization of the American Option
(Taylor & Frances Online, 2008)
The valuation of American options is an optimal stopping time problem which typically leads to a free boundary problem. We introduce here the randomization of the exercisability of the option. This method considerably ...
Emerging Pedagogies in the Middle East: Enhancing Student Autonomy Using Weblogs (Blogs)
(The University of Buckingham Press, 2008)
Students in the Middle East have typically been taught English following traditional, rote learning methods. There has been little time, or little room, within the set curriculum for teachers to enrich their students’ ...
