Spontaneous symmetry breaking in a spin-orbit-coupled f=2 spinor condensate
(Amer Physical Soc, 2015)
Do transience gravity waves in a shear flow break?
(John Wiley & Sons Ltd, 2008-07-10)
The propagation of transient gravity waves in a shear flow towards their critical levels is examined using a ray tracing approximation and a higher-degree (quasi-optic) approximation. Because of its transient forcing, the ...
A time dependent Bayesian nonparametric model for air quality analysis
(Elsevier, 2016)
Air quality monitoring is based on pollutants concentration levels, typically recorded in
metropolitan areas. These exhibit spatial and temporal dependence as well as seasonality
trends, and their analysis demands flexible ...
Weak ergodicity breaking induced by global memory effects
(American Physical Society, 2016-08-08)
We study the phenomenon of weak ergodicity breaking for a class of globally correlated random walk dynamics defined over a finite set of states. The persistence in a given state or the transition to another one depends on ...
Time-frequency analysis of acoustic noise produced by breaking of crisp biscuits
(ELSEVIER SCI LTD, 2008)
This paper demonstrates by means of joint time-frequency analysis that the acoustic noise produced by the breaking of biscuits is dependent on relative humidity and water activity. It also shows that the time-frequency ...
The effects of external and internal strikes on total factor productivity
(Escola de Pós-Graduação em Economia da FGV, 2007-10-01)
This paper examines structural changes that occur in the total factor productivity (TFP) within countries. It is possible that some episodes of high economic growth or economic decline are associated with permanent ...
BREAKING WAVES IN AN IDEAL QUARK GLUON PLASMA
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
We study the propagation of perturbations in the energy density in a quark gluon plasma. Expanding the Euler and continuity equations of relativistic hydrodynamics around equilibrium configurations we obtain a nonlinear ...
