In this work, we have theoretically studied the effect of thermal radiation and thermal diffusion on unsteady MHD free convection heat and mass transfer flow of an

Thus, in this paper, we study a two-phase fluid model for blood flow through mild stenosed narrow arteries of diameter 0.02 mm–0.1 mm at low-shear rates γ < ˙ 10/sec treating

In [11] a model for diffusion of a single phase fluid through a periodic partially- fissured medium was introduced; it was studied by two-scale convergence in [9], and in [40]

In this paper, we consider a Leslie-Gower predator-prey type model that incorporates the prey “age” structure an extension of the ODE model in the study by Aziz-Alaoui and Daher

The excess travel cost dynamics serves as a more general framework than the rational behavior adjustment process for modeling the travelers’ dynamic route choice behavior in

(The origin is in the center of each figure.) We see features of quadratic-like mappings in the parameter spaces, but the setting of elliptic functions allows us to prove the

The main novelty of this paper is to provide proofs of natural prop- erties of the branches that build the solution diagram for both smooth and non- smooth double-well potentials,

Here we consider the problem of whether the hyperbolicity of a dynamics in upper trian- gular form, and more generally in block upper triangular form, can be deduced from the
