Meteorological droughts can affect large areas and may have serious environmental, social and economic impacts. These impacts depend on the severity, duration, and spatial extent of the precipitation deficit and the socioeconomic vulnerability of the affected regions. This paper examines the...

This paper compares Bertrand and Cournot equilibria in a differentiated duopoly with linear demand, and asymmetric constant marginal cost under endogenous timing. It shows that endogenous timing leads to two sequential play with both leader-follower configurations in Bertrand, but simultaneous...

A systematic study of unrelaxed and relaxed surface characters on the TiO2 (101) surface has been carried out by first-principles calculations using plane-wave pseudopotential method. We find that O2c atoms have an inward relaxation of 0.012 Å and Ti5c atoms have an outward relaxation of 0.155...
