In the case of bipartite two-qubit systems,we derive an analytical expression of bound Bell operator for any given pure state.Our result not only manifests some
The plasma electrolytic carbonitriding (PEC/N) process is applied to cast iron using an aqueous solution of acetamide and glycerin as the electrolyte.Mechanical
Tantalum-doped TiO2 films were deposited on glass at 300℃ by pulsed laser deposition (PLD).After postannealing in vacuum (~10-4 Pa) at temperatures ranging from
In clinical practice, brain death is the irreversible end of all brain activity.Compared to current statistical methods for the determination of brain death, we
We focus on the effects of individuals degrees on spontaneous cooperation.By investigating evolutionary PDGs on random networks with two distinct degrees,we fin
A novel controllable hybrid-anode AlGaN/GaN field-effect rectifier (HA-FER) with low operation voltage (LOV)is proposed.Its mechanism can be explained by the fi
