Porous CoAl 3 intermetallic is a candidate material in the field of catalytic and filtration due to its high porosity, good thermostability and quasicrystal structure. However, its rapid and reliable preparation are still a challenge, and the high-temperature antioxidant mechanism need to be...

"Recent volatility in food prices and the growing disparity between prices at various stages of the marketing channel has generated much interest among agricultural producers, consumers, and policy makers. This study examines the effect of nonlinear threshold dynamics on asymmetric price...

In this paper, we propose a delayed predator–prey model with birth pulse and impulsive harvesting in a polluted environment. Existence conditions of the predator-extinction periodic solution are derived by developing the discrete dynamical system, which is determined by the stroboscopic map....

We examine whether firms’ multinationality leads to better performance and what the role of R&D investment is in the multinationality performance linkage. Unlike the previous studies, we employ both accounting‐ and market‐based measures of firm performance for a large sample of U.S....
