Correctly accounting for radiofrequency spillover in saturation transfer experiments: application to measurement of the creatine kinase reaction rate in human forearm muscle
Autor: Alena Horská, G. S. Spencer
Publikováno v: Magma: Magnetic Resonance Materials in Physics, Biology, and Medicine. 5:159-163
Measurements based on transfer of magnetization have been widely used to calculate reaction rates in systems with slow chemical exchange. In these experiments, correction for direct irradiation of the observed resonance is in general accomplished by

Laser-frequency dependence of Raman modes in GaAsAlAs superlattices
Autor: Loren Pfeiffer, G. S. Spencer, Ken W. West, Jose Menendez
Publikováno v: Solid State Communications. 97:21-25
The excitation frequency dependence of the Raman spectra in short-period GaAsAlAs superlattices is studied. The off-resonance Raman spectra can be explained by a disorder-induced breakdown of wave-vector conservation leading to the contribution of

Optical-phonon Raman-scattering study of short-period GaAs-AlAs superlattices: An examination of interface disorder
Autor: Loren Pfeiffer, G. S. Spencer, Jose Menendez, Ken W. West
Publikováno v: Physical Review B. 52:8205-8218
The effect of cation intermixing on the Raman spectrum of GaAs-AlAs superlattices has been investigated. Experimental measurements are compared with theoretical predictions based on fully three-dimensional supercell calculations. The accuracy of the

Raman spectroscopy study of microscopic strain in epitaxial Si1−x−yGexCy alloys
Autor: N. Cave, J. W. Strane, G. S. Spencer, Jose Menendez, Padma Gopalan
Publikováno v: Applied Physics Letters. 66:1160-1162
Raman spectroscopy is used to characterize the microscopic bond structure of Si1−x−yGexCy alloys epitaxially grown on Si substrates by C implantation into Si1−xGex epilayers and subsequent annealing. The Ge and C concentrations in these alloys

Function and bioenergetics in isolated perfused trained rat hearts
Autor: Peter M. Buttrick, R. G. S. Spencer, Joanne S. Ingwall
Publikováno v: The American journal of physiology. 272(1 Pt 2)
To evaluate the resistance of physiologically hypertrophied hearts to hypoxic insult, we quantified the development of functional deficits during hypoxia and reoxygenation in hypertrophied hearts from swim-trained female rats and we correlated this w

Hormone and metabolite changes with stress in stress-susceptible pietrain pigs
Autor: G S, Spencer
Publikováno v: Endocrine regulations. 28(2)
Pigs of the stress-susceptible Pietrain breed, weighing about 60 kg liveweight, were fitted with indwelling jugular vein catheters which were exteriorized between the shoulders to allow stress-free blood sampling. After surgery, the animals were plac
