On the Importance of Hubs in Hopfield Complex Neuronal Networks under Attack
E. P. Rodrigues, M. S. Barbosa, L. da F. Costa
The organizational principles behind the connectivity of a complex network are known to influence its behavior. In this work we investigate, using the Hopfield model, the influence…
Spectral Detrended Fluctuation Analysis and Its Application to Heart Rate Variability Assessment
Luciano da Fontoura Costa, Ruth Caldeira de Melo, Ester da Silva +2
Detrend fluctuation analysis (DFA) has become a choice method for effective analysis of a broad variety of nonstationary signals. We show in the present article that, provided the…
Analytical procedure to determine the self-referred lacunarity function for simple shapes. Supplementary material
Erbe P. Rodrigues, Marconi. S. Barbosa, Luciano da F. Costa
The analytical calculation of the self-referred lacunarity is used as a validation standard of the computational algorithm. In this supplementary material to our article (see cond-…
On the Potential of the Excluded Volume and Auto-Correlation as Neuromorphometric Descriptors
L. da F. Costa, M. S. Barbosa, V. Coupez
This work investigates at what degree two neuromorphometric measurements, namely the autocorrelation and the excluded volume of a neuronal cell can influence the characterization a…
Active percolation analysis of pyramidal neurons of somatosensory cortex: A comparison of wildtype and p21H-ras^Val12 transgenic mice
Luciano da Fontoura Costa, Marconi Soares Barbosa, Andreas Schierwagen +3
This article describes the investigation of morphological variations among two set of neuronal cells, namely a control group of wild type rat cells and a group of cells of a trange…
Percolation and roughness in ballistic deposition of complex shapes
Linder C. da Silva, Marconi S. Barbosa, Osvaldo N. Oliveira +1
This paper investigates how the measurement of geometrical features of structures obtained from ballistic deposition of objects with complex shapes, particularly neuronal cells, ca…
