Ghost condensates and pure kinetic kk-essence condensates in presence of field-fluid non-minimal coupling in the dark sector

In this article we try to find out the conditions when a ghost field in conjunction with a barotropic fluid produces a stable accelerating expansion phase of the universe. It is seen that in many cases the ghost field produces a condensate and drives the fluid energy density to zero in the final accelerating phase, but there can be other possibilities. We have shown that a pure kinetic $k$-essence field (which is not a ghost field) interacting with a fluid can also form an interaction induced condensate and produce a stable accelerating phase of the universe. In the latter case the fluid energy density does not vanish in the stable phase.Comment: Corrected and modified version. 25 pages, Accepted for publication in Univers

The maid behind "The Handmaid’s Tale": A tainted view of Half-hanged Mary

Although much has been debated about the role of syphilis in the witch hunting craze that swept across Europe in the 16th and 17th Century, the equally horrifying Witch Trials in the United States of America were all bracketed under the common heading of ergotism. Here, I focus on one specific case in particular, which is peculiar owing to many factors, not the least being the fact that the woman who was hanged after being accused of witchcraft, eventually lived
