The electronic structure and optical spectrum of monolayer MoS<Subscript>2</Subscript> are calculated using both the modified Becke-Johnson (mBJ) approximation and Bethe-Salpeter equation. Bulk MoS<Subscript>2</Subscript> is an indirect band gap semiconductor, but thinned to a monolayer it converts to a direct band gap semiconductor with...</subscript></subscript>

The aim of this note is to study the properties of some nonstationary autoregressive-moving average (ARMA) processes that are considered important in real world situations. In particular, the covariance structure and linear predictors are obtained.

Climate change is projected to intensify drought and heat stress in groundnut (Arachis hypogaea L.) crop in rainfed regions. This will require developing high yielding groundnut cultivars that are both drought and heat tolerant. The crop growth simulation model for groundnut (CROPGRO-Groundnut...
