Effects of increased heart rate and sympathetic tone on intraventricular electrogram morphology
(Elsevier, 1991-11-15)
Electrogram pattern recognition by way of morphologic analysis has been proposed as a technique that may improve discrimination of ventricular tachycardia from sinus rhythm by anti-tachycardia devices. The potential impact ...
Sinusoidal flicker characteristics of the color-sensitive mechanisms of the eye
(Elsevier, 1969-05)
The flicker characteristics of the color-receptive systems of the eye were investigated by measuring the modulation thresholds for sinusoidal flicker of one color superimposed on a background of a complimentary color. A ...
Interactions of the horizontal and vertical human oculomotor systems: The vertical smooth pursuit and horizontal saccadic systems
(Elsevier, 1972-01)
The human oculomotor system has been studied by numerous people for well over half a century. Since the visual system is our primary sensory input channel, it is important for us to know how information is processed by the ...
Preliminary results from intensity-based CT-SPECT fusion in I-131 anti-B1 monoclonal-antibody therapy of lymphoma Presented in part at the Sixth Conference on Radioimmunodetection and Radioimmunotherapy of Cancer, Princeton, New Jersey, October 10-12, 1996.
(John Wiley & Sons, Inc., 1997-12-15)
BACKGROUND In treatment of non-Hodgkin's lymphoma patients with predose-plus-I-131-labeled anti-B1 (anti-CD20) monoclonal antibody, an intratherapy single photon emission computed tomography (SPECT) image is an important ...
Quantitative studies of sequential peripheral nerve fiber diameter histograms and biophysical implications
(Elsevier, 1977-12)
Peripheral nerve cross sections were analyzed for the variation in peripheral nerve histograms obtained along a single short segment of cat saphenous nerve. Individual myelinated fibers in one fascicle were traced through ...
Square root intensity coding in turtle cones: Physiological mechanisms
(Elsevier, 1990)
The effect of coupling on the intensity-response functions for full field and for slit stimuli was studied by comparing the shapes of the curves obtained from several strongly coupled red cones of turtle with that of one ...
Stability of multi-component epilayers and nanopattern formation
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-10)
A uniform multi-component epilayer may lose stability under the combined action of spinodal decomposition and epilayer–substrate interaction, separating into multiple phases. The phases may further self-organize into regular ...
An Implantable Microsystem for Tonometric Blood Pressure Measurement
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-12)
This paper presents an implantable microsystem for tonometric blood pressure measurement in small animals. The microsystem consists of four major components: (1) a titanium base for supporting a pressure sensor and an ...
An algorithm for the quantification of ST-T segment variability
(Elsevier, 1989-08)
A template boundary algorithm which quantitatively determines repolarization (ST-T segment) variability in a normal population has been developed. The algorithm defines an initial ST-T template for comparison with successive ...
