Purpose – Based on the American antidumping cases against China, the purpose of this paper is to construct an early warning model for Chinese exports. Design/methodology/approach – In order to overcome the drawbacks of the existing early warning models for antidumping, first, the authors...

Biomedical studies suggest that a person?s behavior matters to health, but these studies usually treat human choice as exogenous. This study shows that individual choices on nutrient intake, exercise and use of medication are influenced by exogenous food prices, wages and nonlabor income. Using...

Domain reversal was performed on both near-stoichiometric and heavily Mg-doped lithium niobate crystals. H+ related defect structures in these two types of crystals were studied through the infrared absorption spectra. It is found that the intensity of some decomposed peaks of absorption band...

We study the ground-state properties of frustrated Heisenberg ferrimagnetic ladders with antiferromagnetic exchange interactions and two types of alternating sublattice spins. In the limit of strong rung couplings, we show that the mixed spin-1/2 and spin-1 ladders can be systematically mapped...

Starting from a general Hamiltonian which may undergo a quantum phase transition (QPT) with the change of a controllable parameter, we obtain a general conclusion that in a sudden quench system, when the final Hamiltonian is fixed, the behavior of the time-averaged expectation of any observable...
