In a recent paper Matilla-García and Marín (2010) propose a novel test to determine whether the dynamics of a time series are generated by a deterministic or a stochastic process. The results presented in the paper need some clarifications.

In a recent paper López et al. (2010) introduce a new test for spatial independence. The test is a generalization of tests developed in Matilla-García (2007) and Matilla-García and Marín (2008). The results derived need some clarification.

In this work, we investigate the dynamics of electromagnetic precursors, recorded prior to significant earthquakes in Greece. The analysis of these signals is performed using Fisher information, which is a powerful tool for investigating complex and non-stationary signals. Our results point to a...

Molecular transport in phase space is crucial for chemical reactions because it defines how pre-reactive molecular configurations are found during the time evolution of the system. Using Molecular Dynamics (MD) simulated atomistic trajectories we test the assumption of the normal diffusion in...
