Abstract: this is the case of man aged 51 admitted due to odynophagia, high fever, polyarthritis, as well as leukocytes with neutrophilia and accelerated erythrosedimentation. during admission it was noted polyserositis, pneumonitis and myocarditis with left cardiac insufficiency, hyper-transaminasemia, hyper-ferritinemia and rheumatoid factor with anti-and of negative double-chain. treatment was started with corticosteroids and immunosuppressive agents (azathioprine). response was not the expected one and it was necessary to change the immunosuppressive agent by methotrexate. febrile polyarthritis of polycyclic evolution is the more frequent presentation of the still's disease in adult. hyper-ferritinemia over 1 000 ng/ml is an useful tool for diagnosis and its normalization is an indicator of therapeutical success. there were neither clinical manifestations nor pathognomonic laboratory tests thus, diagnosis remains by exclusion.
Using the Magnitude-Squared Coherence for Determining Order-Chaos Transition in a System Governed by Logistic Equation Dynamics
Carlos R. Fadragas,Rubén Orozco Morales
Physics , 2003,
Abstract: This paper is devoted to show the results obtained by using the magnitude-squared coherence for determining order-chaos transition in a system described by the logistic equation dynamics. For determining the power spectral density of a chaotic finite-duration discrete-time sequence the Welch average periodogram method was used. This method has the advantage that can be applied to any stationary signal by using the discrete Fourier transform (DFT) representation of a discrete-time series which allows an effective computation via fast Fourier transform (FFT) algorithm, and that can be applied to a discrete-time series shorter than that required by nonlinear dynamical analysis methods. The estimate of the Inverse Average Magnitude-Squared Coherence Index (IAMSCI) for each discrete-time series in the set obtained from the logistic mapping was calculated. The control parameter, {\bf r}, ranges in the interval [2.8,4] for producing the discrete-time series set. When the condition $r \geq 3.57$ is satisfied, each discrete-time series exhibited a positive value for IAMSCI estimate, indicating a high level of coherence loss of the signal and corresponding to a chaotic behavior of the dynamical system. Its effectiveness was demonstrated by comparing the results with those obtained by calculating the largest Lyapounov exponent of the time series set obtained from the logistic equation.
Applying the Inverse Average Magnitude Squared Coherence Index for Determining Order-Chaos Transition in a System Governed by Hénon Mapping Dynamics
Carlos R. Fadragas,Rubén Orozco Morales
Physics , 2003,
Abstract: The quantitative determination of the order-chaos transition in a nonlinear dynamical system described by H\'enon mapping defined as $x[n+1]=1.0-A*x[n]^2+B*y[n], y[n+1]=B*x[n]$, where $B=0.3$, and $A$ is an adjustable control parameter, was made. This was achieved by applying the Inverse Average Magnitude-Squared Coherence Index (IAMSCI). This method is based on the Welch average periodogram technique and it has the advantage respect to nonlinear dynamical methods that it may be applied to any stationary signal by using discrete Fourier transform (DFT) representation which allows to operate on a short discrete-time series. Its effectiveness was demonstrated by comparing the results obtained by applying IAMSCI method with those obtained by calculating the largest Lyapounov exponent (LLE), both applied to the same discrete-time series set derived from the H\'enon mapping.
Feasibility for p+/p- flow-ratio evaluation in the 0.5 - 1.5 TeV primary energy range, based on Moon-shadow muon measurements, to be carried out in the Pyramid of the Sun, Teotihuacan, Experiment

Physics , 2007,
Abstract: Calculations are presented to demonstrate the feasibility of Moon shadow observations for mean primary energies in the region 0.5-1.5 TeV using a muon detector operating under the Pyramid of the Sun at Teotihuacan, Mexico. Due to the small height of that monument (65 m), the experiment is capable of providing considerably high statistics, although with reduced angular accuracy for primary particle direction reconstruction. Our estimates are based on simulations of muon production and transport in the atmosphere by CORSIKA and along the body of the pyramid by GEANT4. The deflection of primaries in the earth magnetic field is calculated using the IGRF model. The statistics for the Moon shadow observations, which depends on different factors affecting the accuracy of the primary particle direction reconstruction, are analyzed in detail.

Applying the DFT representation for describing the order-chaos transition in Hénon mapping dynamics
Carlos R. Fadragas,Ruben Orozco-Morales,Juan V. Lorenzo-Ginori
Physics , 2002,
Abstract: The DFT representation is applied, to a ordered-chaotic finite-duration sequences set generated by the H\'enon mapping, for describing the order-chaos transition. This representation has the advantage that it may be applied to a relatively shorter discret-time series. The bifurcation diagram is produced and the largest Lyapounov exponent is calculated for each time series of the set, showing a good agreement with the results obtained by the DFT representation. The threshold value of the control parameter for the order-chaos transition was determined to be A=1.0532.
Possibilities of the Discrete Fourier Transform for Determining the Order-Chaos Transition in a Dynamical System
Carlos R. Fadragas,Juan V. Lorenzo-Ginori,Ruben Orozco-Morales
Physics , 2002,
Abstract: This paper is devoted to a discussion of the Discrete Fourier Transform (DFT) representation of a chaotic finite-duration sequence. This representation has the advantage that is itself a finite-duration sequence corresponding to samples equally spaced in the frequency domain. The Fast Fourier Transform (FFT) algoritm allows us an effective computation, and it can be applied to a relatively short time series. DFT representation requirements were analized and applied for determining the order-chaos transition in a nonlinear system described by the equation $x[n+1]=rx[n](1-x[n])$. Its effectiveness was demonstrated by comparing the results with those obtained by calculating the largest Lyapounov exponent for the time series set, obtained from the logistic equation.
