A fractal analysis of skin pigmented lesions using the novel tool of the variogramm technique
No full textThe incidence of the cutaneous malignant melanoma is increasing rapidly in the world [Ferlay J, Bray F, Pisani P,
et al. GLOBOCAN 2000: Cancer incidence, mortality and prevalence worldwide, Version 1.0 IARC Cancer Base no. 5.
Lyon: IARC Press, 2001]. The therapeutic address requires a method having high sensitivity and capability to diagnose
such disease at an early stage. We introduce a new diagnostic method based on non-linear methodologies. In detail we
suggest that fractal as well as noise and chaos dynamics are the most important components responsible for genetic
instability of melanocytes. As consequence we introduce the new technique of the variogram and of fractal analysis
extended to the whole regions of interest of skin in order to obtain parameters able to identify the malignant lesion.
In a preliminary analysis, satisfactory results are reached

No full textA new method based on fractal variance function for analysis and quantification of sympathetic and vagal activity in variability of R-R time series in ECG signals
No full textIt is known that R–R time series calculated from a recorded ECG, are strongly correlated to
sympathetic and vagal regulation of the sinus pacemaker activity. In human physiology it is
a crucial question to estimate such components with accuracy. Fourier analysis dominates
still to day the data analysis efforts of such data ignoring that FFT is valid under some crucial
restrictions that results largely violated in R–R time series data as linearity and stationarity.
In order to go over such approach, we introduce a new method, called CZF. It
is based on variogram analysis. It is aimed from a profound link with Recurrence Quantification
Analysis that is a basic tool for investigation of non linear and non stationary time
series. Therefore, a relevant feature of the method is that it finally may be applied also in
cases of non linear and non stationary time series analysis. In addition, the method enables
also to analyze the fractal variance function, the Generalized Fractal Dimension and, finally,
the relative probability density function of the data. The CZF gives very satisfactory results.
In the present paper it has been applied to direct experimental cases of normal subjects,
patients with hypertension before and after therapy and in children under some different
conditions of experimentation

No full textAbstract
We introduce the quantum theoretical formulation to determine a posteriori, if
existing, the quantum wave functions and to estimate the quantum interference
effects of mental states. Such quantum features are actually found in the case of
an experiment involving the perception and the cognition in humans. Also some
specific psychological variables are introduced and it is obtained that they
characterize in a stringent manner the quantum behaviour of mind during such
performed experiment
Fractal Fluctuations and Quantum-Like Chaos in the Brain by Analysis of Variability of Brain Waves: A New Method Based on a Fractal Variance Function and Random Matrix Theory: A link with El Naschie fractal Cantorian space time and V. Weiss and H. Weiss golden ratio in Brain
No full textWe develop a new method for analysis of fundamental brain waves as recorded by the EEG.
To this purpose we introduce a Fractal Variance Function that is based on the calculation of
the variogram. The method is completed by using Random Matrix Theory. Some examples
are given. We also discuss the link of such formulation with H. Weiss and V. Weiss golden
ratio found in the brain, and with El Naschie fractal Cantorian space-time theory
The Fractal Variogram Analysis as General Tool to Measure Normal and Altered Metabolism States and the Genetic Instability: An Application to the Case of the Cutaneous Malignant Melanoma
No full textWe discuss a new methodology that uses the Fractal Variance Function, the Generalized Fractal Dimension, the Fractal Measure and the Probability Distributions in the framework of a variogram analysis in order to characterize normal and altered states of the biological dynamics. Its relevance is evidenced through an analysis of some cases of melanoma
