Branching of periodic orbits in reversible hamiltonian systems [PDF]

Real and complex singularities, 46-70, London Math. Soc. Lecture Note Ser., 380, Cambridge Univ. Press, Cambridge, 2010, 2010
This paper deals with the dynamics of time-reversible Hamiltonian vector fields with 2 and 3 degrees of freedom around an elliptic equilibrium point in presence of symplectic involutions. The main results discuss the existence of one-parameter families of reversible periodic solutions terminating at the equilibrium.

Chaos, Dissipation and Quantal Brownian Motion [PDF]

in Proceedings of the International School of Physics `Enrico Fermi' Course CXLIII "New Directions in Quantum Chaos", Edited by G. Casati, I. Guarneri and U. Smilansky, IOS Press, Amsterdam, 2000, 1999
Energy absorption by driven chaotic systems, the theory of energy spreading and quantal Brownian motion are considered. In particular we discuss the theory of a classical particle that interacts with quantal chaotic degrees of freedom, and try to relate it to the problem of quantal particle that interacts with an effective harmonic bath.

Resistiendo el clientelismo. Publicidad gubernamental y subsistencia de la prensa crítica

Colombia Internacional, 2018
Clientelism is one of the most widely used strategies in hybrid regimes which give rulers an advantage when they play against the opposition. The literature on the subject has focused on electoral clientelism, but we know little about the dynamics ...

Gauge Symmetry of the Third Kind and Quantum Mechanics as an Infrared Phenomenon [PDF]

Sense of Beauty in Physics: A Volume in Honour of Adriano Di Giacomo, edited by M. D'Elia, K. Konishi, E. Meggiolaro, P. Rossi (Edizioni Plus, Pisa University Press, Pisa, 2006), 275-286, 2006
We introduce functional degrees of freedom by a new gauge principle related to the phase of the wave functional. Thereby, quantum mechanical systems are seen as dissipatively embedded part of a nonlinear classical structure producing universal correlations. There are a fundamental length and an entropy/area parameter, besides standard couplings.

Pers, demokrasi dan negara Indonesia Post-Soeharto: Sebuah perspektif

Masyarakat, Kebudayaan dan Politik, 2014
The resignation of President Soeharto in May 1998 marked the end of new order era and started a fundamental change within democracy in Indonesia. As a democratic state, Indonesia arguably provides a system to guarantee the freedom of press and good ...

Cross-country Association of Press Freedom and LGBT freedom with prevalence of persons living with HIV: implication for global strategy against HIV/AIDS

Global Health Research and Policy, 2018
Background Human behaviors are affected by attitudes and beliefs, which in turn are shaped by higher-level values to which we have ascribed. In this study, we explore the relationship between two higher-level values, press freedom and LGBT freedom, and ...

CKM Matrix Elements: Magnitudes, Phases, Uncertainties [PDF]

arXiv, 1994
Schemes for fermion masses should predict elements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. We review the freedom allowed by present experiments and how the parameter space will shrink in the next few years. In addition to experiments which directly affect CKM parameters, we discuss constraints arising from precise electroweak tests.
