We report the near through mid-infrared (MIR) optical absorption spectra, over the range 0.05–1.3 eV, of monocrystalline silicon layers hyperdoped with chalcogen atoms synthesized by ion implantation followed by pulsed laser melting. A broad mid-infrared optical absorption band emerges, peaking near 0.5 eV for sulfur and selenium and 0.3 eV for tellurium(More)
When opposing teeth with amalgam and gold restoration are in contact, current flows in the mouth at the instant the dissimilar metals touch. In this study, this condition was simulated by use of resistors and extracted human teeth with amalgam and MOD gold inlay restorations. When both teeth were in contact in a physiological saline solution, we measured(More)
A small experimental impression tray was fabricated with a NiTi shape memory alloy plate. After recovery of the shape memory effect, the upper rims of the tray holding the impression were opened to some extent, the resistance during removal of the model from the impression was significantly decreased compared to a commercially available tray and the tray(More)
Polycrystalline thin films of La-substituted bismuth titanate (BLT) have been formed directly on p-type Si(100) substrates by using sol-gel and spin-coat methods. The BLT film and interfacial layer between BLT and Si were quantitatively investigated by X-ray reflectivity method. Also, crystal orientations of sub-100 nm-thick BLT thin films have been(More)
BACKGROUND Over 100 limited sampling strategies (LSSs) have been proposed to reduce the number of blood samples necessary to estimate the area under the concentration-time curve (AUC). The conditions under which these strategies succeed or fail remain to be clarified. OBJECTIVES We investigated the accuracy of existing LSSs both theoretically and(More)
