Spherical space in the Newtonian limit: The cosmological constant
J. M. Isidro, P. Fernandez de Cordoba, J. C. Castro-Palacio
We compute the cosmological constant of a spherical space in the limit of weak gravity. To this end we use a duality developed by the present authors in a previous work. This duali…
Machinery Failure Approach and Spectral Analysis to study the Reaction Time Dynamics over Consecutive Visual Stimuli
M. E. Iglesias-Martínez, M. Hernaiz-Guijarro, J. C. Castro-Palacio +3
The reaction times of individuals over consecutive visual stimuli have been studied using spectral analysis and a failure machinery approach. The used tools include the fast Fourie…
The cosmological constant of emergent spacetime in the Newtonian approximation
J. C. Castro-Palacio, P. Fernandez de Cordoba, J. M. Isidro
We present a simple quantum-mechanical estimate of the cosmological constant of a Newtonian Universe. We first mimic the dynamics of a Newtonian spacetime by means of a nonrelativi…
Correlations between Background Radiation inside a Multilayer Interleaving Structure, Geomagnetic Activity, and Cosmic Radiation: A Fourth Order Cumulant-based Correlation Analysis
M. E. Iglesias-Martínez, J. C. Castro-Palacio, F. Scholkmann +7
In this work, we analyzed time-series of background radiation inside a multilayer interleaving structure, geomagnetic activity and cosmic-ray activity using the Pearson correlation…
Brain reaction times: Linking individual and collective behaviour through Physics modelling
Juan Carlos Castro-Palacio, Pedro Fernández de Córdoba, J. M. Isidro +1
An individual's reaction time data to visual stimuli have usually been represented in Experimental Psychology by means of an ex-Gaussian function (EGF). In most previous works, res…
Theoretical and experimental study of the normal modes in a coupled two-dimensional system
Marcos H. Giménez, Juan Carlos Castro-Palacio, José Antonio Gómez-Tejedor +2
In this work, the normal modes of a two-dimensional oscillating system have been studied from a theoretical and experimental point of view. The normal frequencies predicted by the…
