We also prove that the MEE possesses appropriate time-independent Hamiltonian function for the full range of parameters $α$ and $β$. In addition, we show that the MEE is intimately connected with two well known nonlinear models, namely the force-free Duffing type oscillator equation and the two dimensional Lotka-Volterra (LV) equation and thus the complete integrability of the latter two models can also be understood in terms of the MEE.12 pages, one figureExactly Solvable and Integrable Systemstext
