The Dynamics of Quintessence, The Quintessence of Dynamics
Quintessence theories for cosmic acceleration imbue dark energy with a non-trivial dynamics that offers hope in distinguishing the physical origin of the component. We review quintessence models with an emphasis on this dynamics and discuss classifications of the different physical behaviors. The pros and cons of various parameterizations are examined as well as the extension from scalar fields...

This case report looks at a case of traumatic avulsion and subsequent apexification of a maxillary permanent incisor of a 6-year-old boy and a 10-year follow-up is reported. Treatment included apexification of the tooth with incomplete root formation using mineral trioxide aggregate and restoration of the immature root with a zirconia post and a coronal composite restoration. At the 10-year fol...

51 isolation through the dental dam) and 2) a biological parameter (depending on the biologic width). Three different clinical situations and three different therapeutic approaches are identified (1 st , 2 nd , and 3 rd , respectively): coronal relocation of the margin , surgical exposure of the margin, and clinical crown lengthening. The latter is associated with three further operative sequen...
متن کاملCoupled Quintessence
A new component of the cosmic medium, a light scalar field or ”quintessence ”, has been proposed recently to explain cosmic acceleration with a dynamical cosmological constant. Such a field is expected to be coupled explicitely to ordinary matter, unless some unknown symmetry prevents it. I investigate the cosmological consequences of such a coupled quintessence (CQ) model, assuming an exponent...
