We study the steady states of some models for van der Waals uid. In particular, for a mass viscosity model, we show that there is no \cavitation" wave. We also consider the closed orbits, heteroclinic orbits, and their relation with Maxwell construction, for diierent models with regularization terms.

We have calculated the analytic expression of GME for arbitrary superposition of two N -qubitW states and two GHZ states. We have also derived the GME for a generic class of states, which is not permutation invariant and of M copies of a pure state. A nice comparison between GHZ and W states w.r.t. GME has been drawn.

although some alternative therapies like botanical and herbal therapies have shown promise for relieving menopause symptoms such as hot flashes, more research is needed. eighty-five percent of the women in the united states experience hot flashes of some kind as they approach menopause and for the first year or two after their periods stop. between 20 and 50% of women continue to have them for ...

classical control methods such as pontryagin maximum principle and bang-bang principle and other methods are not usually useful for solving opti-mal control systems (ocs) specially optimal control of nonlinear systems (ocns). in this paper, we introduce a new approach for solving ocns by using some combination of atomic measures. we define a criterion for controllability of lumped nonlinear con...

In this paper, we generalize the definitions of approximately inner $C_0$-groups and their ground states to the two- parameter case and study necessary and sufficient conditions for a state to be ground state. Also we prove that any approximately inner two- parameter $C_0$--group must have at least one ground state. Finally some applications are given.

subject of this article is the deprivation that relate to wives and their portion in patrimony of their husband. as most imamiah’s jurists state; wives are deprived from possessing some objects in the case of husband’s death. in the other hand, some jurists mentioned that wives are same as other and that deprivation is not acceptable. majority states that this statute belongs to a kind of wives...
