Advances in periodic difference equations with open problems
(Springer, 2014)
In this paper, we review some recent results on the dynamics of semi-dynamical systems generated by the iteration of a periodic sequence of continuous maps. In particular, we state several open problems focused on the ...
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 ...
Effect of pH, ultrasound frequency and power density on the release of calcein from stealth liposomes
(De Gruyter, 2016)
The use of liposomes as carriers for chemotherapeutic agents in combination with ultrasound as a stimulus to control the time and space of the drug release is a promising approach for cancer treatment, as it can reduce the ...
A new characterization of periodic oscillations in periodic difference equations
(Elsevier, 2011-11)
In this paper, we characterize periodic solutions of p-periodic difference equations. We classify the periods into multiples of p and nonmultiples of p. We show that the elements of the set of multiples of p follow the ...
Verbal negation in the Lebanese dialect of Zeitoun, Keserwan
(Institut de recherches et d’études sur les mondes arabes et musulmans (IREMAM), 2019)
The dialect of Zeitoun village in the northern Keserwan district of Lebanon exhibits both the split-morpheme negators mā…š of the southern and highland Levant and the pre-verbal negator mā without the post-positive -š of ...
Muslim Women's Evolving Leadership Roles: A Case Study of Women Leaders in an Immigrant Muslim Community in Post-9/11 America
(Sage, 2017)
Based on three years of ethnographic fieldwork in a multi-ethnic immigrant Muslim congregation in a Midwestern city in the United States, this paper scrutinizes the intricate process through which women uses traditional ...
On the dot product graph of a commutative ring II
(International Electronic Journal of Algebra, 2020)
In 2015, the second-named author introduced the dot product graph associated to a commutative ring A. Let A be a commutative ring with nonzero identity, 1 ≤ n < ∞ be an integer, and R = A × A × · · · × A (n times). We ...
Becomings in J. M. Coetzee's Waiting for the Barbarians and José Saramago's Blindness
(The Pennsylvania State University, 2010)
Highly variable upper and abyssal overturning cells in the South Atlantic
(American Association for the Advancement of Science, 2020-08-05)
The Meridional Overturning Circulation (MOC) is a primary mechanism driving oceanic heat redistribution on Earth, thereby affecting Earth's climate and weather. However, the full-depth structure and variability of the MOC ...
Folding and unfolding in periodic difference equations
(Elseiver, 2014)
Given a p-periodic difference equation xn+1 = fn mod p(xn), where each fj is a continuous interval map, j = 0, 1, . . . , p − 1, we discuss the notion of folding and unfolding related to this type of non-autonomous equations. ...
