On the stability of the Einstein Static Universe in Massive Gravity [PDF]
Phys. Rev. D 86, 024035 (2012), 2012 We consider static cosmological solutions along with their stability properties in the framework of a recently proposed theory of massive gravity. We show that the modifcation introduced in the cosmological equations leads to several new solutions, only sourced by a perfect fluid, generalizing the Einstein Static Universe found in General Relativity ...

Does the entropy of the Universe tend to a maximum? [PDF]
, 2012 Ordinary, macroscopic systems, naturally tend to a state of maximum entropy compatible with their constraints. However, this might not hold for gravity-dominated systems since their entropy may increase without bound unless this is precluded by the formation of a black hole. In this short note we suggest, based on the Hubble expansion history, that our

A thermodynamic characterization of future singularities? [PDF]
, 2012 In this Letter we consider three future singularities in different Friedmann-Lema\^{\i}tre-Robertson-Walker scenarios and show that the universe departs more and more from thermodynamic equilibrium as the corresponding singularity is approached.

Thermodynamics of the unified dark fluid with fast transition [PDF]
, 2014 In the so-called unified dark fluid models, the dark sector gets simplified because dark matter and dark energy are replaced by a single fluid that behaves as the former at early times and as the latter at late times. In this short paper we analyze this class of models from the thermodynamic viewpoint.

Candomblé and the Academic's Tools: Religious Expertise and the Binds of Recognition in Brazil
American Anthropologist, Volume 121, Issue 4, Page 815-829, December 2019., 2019 ABSTRACT Latin American state efforts to recognize ethnically and racially marked populations have focused on knowledge and expertise. This article argues that this form of state recognition does not only call on subaltern groups to present themselves in a frame of expertise.

Constraining the Schwarzschild-de Sitter Solution in Models of Modified Gravity [PDF]
Phys. Dark Univ. 13 (2016) pp. 111-120, 2016 The Schwarzschild-de Sitter (SdS) solution exists in the large majority of modified gravity theories, as expected, and in particular the effective cosmological constant is determined by the specific parameters of the given theory. We explore the possibility to use future extended radio-tracking data from the currently ongoing New Horizons mission in ...

Structural Insights into the HWE Histidine Kinase Family: The Brucella Blue Light-Activated Histidine Kinase Domain [PDF]
, 2016 In response to light, as part of a two-component system, the Brucella blue light-activated histidine kinase (LOV-HK) increases its autophosphorylation, modulating the virulence of this microorganism.
