Modern Physics Letters A, 2006 The Observed Perlmutter-Riess Acceleration (OPRA) implies that the expansion of the Universe is currently increasing and is motivation for the so-called phantom energy models. We consider the dynamics of phantom scalar field models. An important physical time constraint, which can be used to rule out many cosmological models, is obtained from the ...

Nuclear Physics B, 2004 This paper deals with the thermodynamic properties of a phantom field in a flat Friedmann-Robertson-Walker universe. General expressions for the temperature and entropy of a general dark-energy field with equation of state $p= $ are derived from which we have deduced that, whereas the temperature of a cosmic phantom fluid ($

Mapping the invisible hand: a body model of a phantom limb [PDF]
, 2012 After amputation, individuals often have vivid experiences of their absent limb (i.e., a phantom limb). Therefore, one’s conscious image of one’s body cannot depend on peripheral input only (Ramachandran & Hirstein, 1998).

Phantom depth and stable phantom exactness [PDF]
Transactions of the American Mathematical Society, 2007 Phantom depth, phantom nonzerodivisors, and phantom exact sequences are analogues of the non-“phantom” notions which have been useful in tackling the (very difficult) localization problem in tight closure theory. In the present paper, these notions are developed further and partially reworked. For instance, although no analogue of a long exact sequence

Vision Research, 2015 It is well known that visible luminance gradients may generate contrast effects. In this work we present a new paradoxical illusion in which the luminance range of gradual transitions has been reduced to make them invisible. By adopting the phenomenological method proposed by Kanizsa, we have found that unnoticeable luminance gradients still generate ...

On phantom thermodynamics [PDF]
Physics Letters B, 2008 The thermodynamic properties of dark energy fluids described by an equation of state parameter $ =p/ $ are rediscussed in the context of FRW type geometries. Contrarily to previous claims, it is argued here that the phantom regime $ 0$ and $S>0$ in the course of the Universe expansion.
