In this paper,we consider the problem of existence as well as multiplicity results for a bi-harmonic equation under the Navier boundary conditions:Δ2u =K(x)up,
This paper gives a recursion operator for a 1-constrained CKP hierarchy,and by the recursion operator it proves that the 1-constrained CKP hierarchy can be redu
This paper is concerned with the initial-boundary value problem for damped wave equations with a nonlinear convection term in the multi-dimensional half space R
An ion chromatography (IC) system coupled with on-line column-switching technique was used to determine anions of μg/g levels in organic chemicals of analytica
Coral reef-like Ni/Al2O3 catalysts were prepared by co-precipitation of nickel acetate and aluminium nitrate with sodium carbonate aqueous solution in the mediu
Herman constructed an autonomous system of two degrees of freedom which says that in non-convex situations, oscillations do happen and Aubry-Mather Theory canno
This paper describes parallel simulation techniques for the discrete element method (DEM) on multi-core processors.Recently,multi-core CPU and GPU processors ha
A series of new amino alcohol derivatives was synthesized and evaluated for their immunosuppressive activity on mouse peripheral blood lymphocytes.The structure
This paper investigates a class of 2nth-order singular superlinear problems with Strum-Liouville boundary conditions.We obtain a necessary and sufficient condit
