In this paper, by using a linking theorem, some new existence criteria of homoclinic orbits are obtained for the p-Laplacian system d(|u̇(t)|p−2u̇(t))/dt + ∇V (t, u(t)) = f(t), where p > 1, V (t, x) = −K(t, x) + W (t, x).

Objective. To evaluate the beneficial and adverse effects of Wenxin Keli (WXKL), either alone or in combination with Western medicine, on the left ventricular ejection fraction (LVEF) and plasma brain natriuretic peptide (BNP) in the treatment of heart failure (HF). Methods. Seven major electronic databases were searched to retrieve potential randomized… (More)

In this paper, we first improve two inequalities, then by using critical point theory, improve an existence theorem of periodic solutions for a nonlinear discrete system involving the p-Laplacian, and present some estimates of periodic solutions.

In this paper, by using the variational approach, we study the existence of infinitely many solutions for a class of second-order damped vibration systems under superquadratic and sub-quadratic conditions. Some new results are established and some recent results in the literature are generalized and significantly improved.

Comprehensive evaluation on health care system of ten countries is discussed in this paper. In order to comprehensively assess and evaluate the health care system in an objective manner, five first-tier indicators and nineteen second-tier indicators are set up as evaluation criteria in the first place. Then entropy modeling and Matlab software are applied… (More)

This paper presents a system entropy model for optimizing the number of tollbooths at highway toll plazas. Highways usually experience severe traffic congestion/jams at toll plazas since vehicles need to stop and wait for toll collection. It is noted that the number of tollbooths directly influences the traffic congestion. In order to obtain the optimal… (More)
