    • Stability and bifurcation analysis of a discrete-time predator-prey model with strong Allee effect 

      Al-Sharawi, Ziyad; Pal, Saheb; Rana, Sourav; Pal, Nikhil; Chattopadhyay, Joydev (Taylor & Francis, 2020-03-16)
      In this paper, we investigate the impact of Allee effect on the stability of a discrete-time predator-prey model with a non-monotonic functional response. The proposed model supports the coexistence of two steady states, ...
    • Strong ring extensions andphi-pseudo-valuation rings 

      Badawi, Ayman; Dobbs, David E. (University of Houston, 2006)
      In this paper, we extend the concept of strong extensions of domains to the context of (commutative) rings with zero-divisors. We show that the theory of strong extensions of rings resembles that of strong extensions of domains.
    • Weighted multimodal family of distributions with sine and cosine weight functions 

      Alzaatreh, Ayman; Kazempoor, Jaber; Nadi, Adel Ahmadi (Cell Press, 2020)
      In this paper, the moment of various types of sine and cosine functions are derived for any random variable. For an arbitrary even probability density function, the sine and cosine moments are used to define new families ...
