The authors of this paper note that although ‘there is general agreement that primary care is the linchpin of effective health care delivery’ there are no systematic reviews of the evidence which may support this. This study aimed to identify the core dimensions of primary care, assessing the evidence for their relation with and relevance to outcomes. Kringos DS, Boerma WGW, Hutchinson A, van d...

Abstract Based on the predator–prey system with a Holling type functional response function, diffusive digest delay and habitat complexity is proposed. Firstly, stability of equilibrium diffusion without studied. Secondly, under Neumann boundary conditions, taking time as bifurcation parameter, by analyzing eigenvalues linearized operator using normal form theory center manifold method partial ...

We consider here a two sided interpolation problem where we want to minimize the degree of the interpolant. We show that this degree is given by the rank of a particular solution to a Sylvester equation which, in some particular cases becomes a Löwner or a Hankel matrix. We consider an application to the usual partial realization problem. The results are quite general and no particular assumpti...

Given two densities f and g, we consider the problem of transporting a fraction m ∈ [0, min{‖f‖L1 , ‖g‖L1}] of the mass of f onto g minimizing a transportation cost. If the cost per unit of mass is given by |x − y|2, we will see that uniqueness of solutions holds for m ∈ [‖f ∧ g‖L1 , min{‖f‖L1 , ‖g‖L1}]. This extends the result of Caffarelli and McCann in [8], where the authors consider two den...
