For a simple model we derive analytic expressions of concurrence and entanglement fidelity and draw the relationship between them. We find that such entanglement fidelity exhibits the behavior similar to that of the concurrence in quantum evolutions.展开更多

The language is closely related to Dani, Walak, and Nggem. It is an SOV language typology that has a complex morphological system. Four spatial dimensions are morphosyntactically coded in elevative deixis, which are steepness/non-steepness distinction, proximity/distality distinction, adverbial/attributive expressions, and vertical/horizontal plane. This paper discusses the grammatical operation of a set of two-term system： ei ＂up＂ and ou ＂down＂ that serves as the basic forms for the elevational deixis in Wano.展开更多
