Infrared studies of hole-plasmon excitations in heavily-doped p-type MBE-grown GaAs : C
(American Physical Society, 2000-08-15)
Infrared reflectivity measurements (200-5000 cm(-1)) and transmittance measurements (500-5000 cm(-1)) have been carried out on heavily-doped GaAs:C films grown by molecular-beam epitaxy. With increasing carbon concentration, ...
Effect of Ba incorporation on pressure-induced structural changes in the relaxor ferroelectric PbSc0.5Ta0.5O3
(American Physical Society, 2009-09-28)
Pressure-induced structural changes in the canonical relaxor Pb0.78Ba0.22Sc0.5Ta0.5O3 were studied with both in-house and synchrotron single-crystal x-ray diffraction as well as Raman spectroscopy at pressures up to 9.8 ...
Comparison of vibrational and electronic contributions to van der Waals interactions
(American Physical Society, 2006-05)
The van der Waals interaction can be caused by either ionic vibrations or instantaneous electronic motion relative to the atomic center. In this study, the vibrational contribution to the van der Waals interaction is ...
Applications of field-theoretic renormalization group methods to reaction-diffusion problems

Invariant measures for the tochastic von Karman plate equation
(Siam Publications, 2005)
We prove the existence of an invariant measure for the von Karman plate equation with random noise. The nonlinear term which symbolizes the von Karman equation inhibits the standard procedure for the existence of an invariant ...
Glucose modulates Ca2+ (i) oscillations in pancreatic islets via ionic and glycolytic mechanisms
(CELL PRESS, 2006-09)
Pancreatic islets of Langerhans display complex intracellular calcium changes in response to glucose that include fast (seconds), slow (similar to 5 min), and mixed fast/slow oscillations; the slow and mixed oscillations ...
Low-resistance films of polyimides with impregnated copper sulfide
(Cambridge University Press, 2001-11)
Surface modification of polyimides has been used to obtain better interaction with an inorganic material. Copper sulfide incorporation onto the surface of commercial Kapton (R) polyimide showed that treatment with base was ...
Time resolved magneto-optical studies of ferromagnetic InMnSb films
(AIP Publishing, 2008-02)
We report time resolved magneto-optical measurements in InMnSb ferromagnetic films with 2% and 2.8% Mn contents grown by low temperature molecular beam epitaxy. In order to probe a possible interaction between the spins ...
The effect of larval diet and sex on nectar nicotine feeding preferences in Manduca sexta (Lepidoptera: Sphingidae)
