    We review the principal statistical properties of the RR interval sequence during atrial fibrillation. A simple quantitative electrophysiologic model is presented which successfully accounts for these statistical features. In this model the atrioventricular junction (AVJ) is treated as a single cell equivalent characterized by a refractory period and spontaneous rate of phase 4 depolarization. The...

  • Predicting Final Eye Position Halfway Through a Saccade

    When the visual environment is to be changed during a saccadic eye movement, it is useful to predict the final eye position before the eye comes to rest. We have built a microcomputer-based instrument to make such predictions. Two techniques were used: one based on the saccadic peak-velocity versus magnitude relationship, and the second based on peak-velocity occurring in the middle of the saccade... View full abstract»

    A recursive, free-body approach to the estimation of joint torques associated with observed motion in linkage mechanisms has recently been shown to be computationally more efficient than any other known approach to this problem. This paper applies this method to the analysis of human postural dynamics and shows how it can also be used to compute accelerations for specified joint torques. The latte... View full abstract»

  • A Cardiac Hypothesis for the Origin of EEG Alpha

    Major hypotheses for the origin of EEG alpha suggest a neural basis, but omit to consider other electrical and mechanical aspects. A cardiac electromechanical hypothesis is proposed. This hypothesis suggests that the natural mechanical frequency of the skull-brain mass is approximately 10 Hz. This has been determined by model and direct measurement. Membrane, liquid junction, electrode, and static... View full abstract»

    To investigate the potentialities of hyperthermia as a cancer therapy, computer simulations have been performed. This simulation consists of two tuccessive steps. First, the heat generated in a distribution of biological tissue when irradiated by a source of electromagnetic radiation is computed. The mathematical tool for determining the disbution of generated heat is the domain-integral-equation ... View full abstract»

  • Geometric Deconvolution: A Meta-Algorithm for Limited View Computed Tomography

    Images reconstructed using a limited number of projections spanning a narrow angular range suffer from a systematic geometric distortion due to the two-dimensional point spread function of the reconstruction process. Applying the projection theorem, we show that the problem of removing this distortion reduces to that of estimating the one-dimensional spread function and deconvolving projections co...

  • Application of Phase Analysis of the Frankenhaeuser - Huxley Equations to Determine Threshold Stimulus Amplitudes

    Applications of the Frankenhaeuser-Huxley model of myelinated nerve have been presented in the literature which involve the determination of threshold amplitudes of current stimuli as a function of various physical parameters. There is no known analytic solution to the equations describing the model, and so threshold amplitudes must be determined by repeated numerical solution of the five-equation... View full abstract»

  • Dual Microcomputer Analysis of Cardiac Transmembrane Action Potentials

    A dual microcomputer system has been developed for automating the analysis of cardiac transmembrane action potentials. This system consists of two microcomputers and supporting function modules which digitize, detect, analyze, and plot the transmembrane action potentials from a cardiac cell impaled with a microelectrode. The action potentials are digitized at two sampling rates for computer proces... View full abstract»

  • Standard Errors on Respiratory Mechanical Parameters Obtained by Forced Random Excitation

    Equations describing the standard errors of forced random impedance data and derived parameters in terms of various data collection and data processing factors were developed and verified. The equation indicate that to obtain reliable estimates: 1) 16 ensembles are adequate when coherence is greater than 0.9, and that 32 ensembles are adequate when the coherence is between 0.8 and 0.9; 2) the impe...

  • Weak Electric Fields Affect Plant Development

    High-strength electric currents and fields can alter plant physiology by the production of heat within the plant tissue and by the ionization of air molecules at the plant tips. It has been suggested that weak low-frequency electric and magnetic filelds may alter germination and early plant development [4], [5], but the question has not been resolved. Our aim was to determine the possible existenc... View full abstract»

    We present an initial report on the design and performance of a device which combines the heating and coagulating effects of a microwave field with the surgical scalpel. The device is intended to control hemorrhage in the surgical treatment of highly vascular organs such as the spleen and liver. Preliminary experiments in splenic surgery using dogs have indicated the utility of this technique. View full abstract»

  • Generation of the State Sensitivity Functions of a Systemic Arterial Model

    Five third-order sensitivity models have been used in [2] to generate the state sensitivity functions of a third-order lumped-parameter system of the modified "Windkessel" systemic arterial model. It is shown under reasonable assumptions that only one sensitivity model of the same order is actually needed to generate the state sensitivity functions with respect to all parameters for the class of s...

    This paper addresses the task of image reconstruction from an incomplete set of projection data. Several methods which first estimate the missing data and then utilize standard reconstruction algorithms to obtain an image are investigated. Results from simulations are presented which illustrate the difficulty in comparing algorithms objectively, particularly when a simple test phantom is chosen. T... View full abstract»
