Kubo's generalized cumulant expansion theorem is used to derive a theoretical expression for the nuclear magnetic resonance (NMR) signal received from a fluid moving in a time-dependent magnetic field gradient. Described ...

The problem of femoral vibration during the reaming process in total hip arthroplasty is examined. These vibrations are modeled as the transverse vibration of a free-simple Euler-Bernoulli beam using a transfer matrix ...

Pressure sores are a serious medical problem, which cause a great deal of economic and physical damage. The old method of skin color identification is not quantitative and is usually unreliable. Among various methods which ...

Epi-fluorescence video microscopy and digital image processing were used to evaluate the effects of three novel anti-platelet agents namely GT-12/I.2HBr (GT-12/I), A4.2HBr and IC, a series of compounds containing the ...

Pliable, biodegradable scaffolds with poly(lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG) blends have been fabricated using a solvent-casting and particulate-leaching technique. This study investigated the ...

Epifluorescent video-microscopy was used to evaluate the effects of a novel antiplatelet agent, IC, on platelet adhesion and aggregation in the formation of mural thrombi. Studies demonstrate that compound concentration ...

This study is concerned with the relationship between the intra- and extracellular potentials associated with the His bundle of the rabbit heart. A Hodgkin-Huxley type model of the Purkinje cell is developed and subsequently ...

We have developed a mathematical model of the rabbit atrial myocyte in order to investigate the ionic bases of rate dependent changes in action potential (AP) wave-shape. Postulated mediators of such changes include rate ...

The distribution of light in a tissue is determined by it's optical properties. Several techniques are available for determining a tissues optical properties, and models are available for predicting the distribution of ...

The inverse problem was solved to reconstruct endocardial electrograms from cavitary electrograms measured with a noncontact multielectrode probe. Noise levels were estimated at each time instant by extrapolating noise ...
