Analysis of cumulative strain in tendons and tendon sheaths
(Elsevier, 1987)
Twenty-five fresh frozen flexor digitorum profundus tendons stratified by sex were subjected to uniaxial step stress and cyclic loads in twelve intact human cadaver hands. By attaching specially designed clip strain gage ...
High-pass filtering to remove electrocardiographic interference from torso EMG recordings
(Elsevier, 1993-01)
SummaryRemoval of electrocardiographic (ECG) contamination of electromyographic (EMG) signals from torso muscles is often attempted by high-pass filtering. This study investigated the effects of the cut-off frequency used ...
Statistical Emission Image Reconstruction for Randoms-Precorrected PET Scans Using Negative Sinogram Values
(IEEE, 2003-10-19)
Many conventional PET emission scans are corrected for accidental coincidence (AC) events, or randoms, by real-time subtraction of delayed-window coincidences, leaving only the randoms-precorrected data available for image ...
Number of contractions to maintain mass and force of a denervated rat muscle
(Wiley Subscription Services, Inc., A Wiley Company, 2004-07)
Within 5 weeks, denervated extensor digitorum longus (EDL) muscles of rats lose 66% of mass, 91% of force, and 76% of fiber cross-sectional area (CSA). We previously determined the parameters of electrical stimulation for ...
Desorption by ultrasound: Phenol on activated carbon and polymeric resin
(Wiley Subscription Services, Inc., A Wiley Company, 1998-07)
An experimental feasibility study of using ultrasound to accomplish the dificult desorption of phenol from activated carbon and polymeric resin adsorbents is discussed. The desorption rates of activated carbon were found ...
The free autografting of entire limb muscles in the cat: Morphology Supported by grants by the Muscular Dystrophy Association to BMC and JAF and an MDA Postdoctoral Fellowship to SAM.
(Wiley Subscription Services, Inc., A Wiley Company, 1977-08)
Normal or pre-denervated extensor digitorum longus (EDL) muscles were successfully grafted in place of the contralateral EDL muscles in cats. Histological preparations of 57 grafts were examined at intervals from 4 to 170 ...
Effect of Including Detector Response in SPECT Quantification of Focal I-131 Therapy
(IEEE, 2001-11-04)
With a regularized strip-integral (1D) SAGE reconstruction, circular-orbit SPECT estimates of phantom focal 131-I activity vary with changes in the level of uniform background. They also vary with changes in image resolution ...
Intensity-Based Image Registration Using Robust Correlation Coefficients
(IEEE, 2004-11-01)
The ordinary sample correlation coefficient is a
popular similarity measure for aligning images from the same
or similar modalities. However, this measure can be sensitive to
the presence of “outlier” objects that appear ...
Incorporation of System Resolution Compensation (RC) in the Ordered-Subset Transmission (OSTR) Algorithm for Transmission Imaging in SPECT
(IEEE, 2006-06-26)
In order to reconstruct attenuation maps with improved spatial resolution and quantitative accuracy, we developed an approximate method of incorporating system resolution compensation (RC) in the ordered-subset transmission ...
Isometric and isokinetic back and arm lifting strengths: Device and measurement
(Elsevier, 1988)
This study was conducted to measure isometric (static) and isokinetic (dynamic) back and arm lifting strengths at 20, 60 and 100 cm s-1 of young adults. Ten male and ten female volunteers without a history of back pain ...
