Nonlinear Analysis of tRNAs Nucleotide Sequences by Random Walks: Randomness and Order in the Primitive Informational Polymers
In order to test the hypothesis that the nucleotide sequences of the primitive informational polymers might not be chosen randomly and in the attempt to compare among taxa, we propose a comparison of computer-...

Fractal Dimension of Lymphocytic Nuclear Membrane in Mycosis Fungoides and Chronic Dermatitis
The nuclear outline was measured by using fractal analysis in six cases of early mycosis fungoides (EMF) and in five cases of chronic dermatitis (CD). Ultrastructural images of approximately 30 nuclei for each...

Fractal Dimension of Epithelial-Connective Tissue Interface in Basal Cell Carcinoma of the Skin
There are still many gaps in the description of the geometry of tumors. Conventional morphometry fails to analyse complex structures, such as tumor boundaries. Fractal geometry on the other hand is a very usef...
