Comment on "Conservative force fields in nonextensive kinetic theory."
F. A. da Costa, M. D. S. de Meneses
We discuss an improper application of the Maxwell-Boltzmann theory to a very unrealistic model. The authors of the original paper claim that a generalized theory would solve a prob…

Power-law temporal auto-correlations in day-long records of human physical activity and their alteration with disease
Luis A. Nunes Amaral, Danyel J. Bezerra Soares, Luciano R. da Silva +5
We investigate long-duration time series of human physical activity under three different conditions: healthy individuals in (i) a constant routine protocol and (ii) in regular dai…
