The temperature dependence of silicon-on-insulator thermo-optic attenuators is analysed, which originates from the temperature dependence of characteristics of
The compressional behaviour of natural pyrope gaet is investigated by using angle-dispersive synchrotron radiation x-ray diffraction and Raman spectroscopy in a
We investigate tie geodetic precession of light in the Schwarzschild spacetime surrounded by quintessence. With the analysis and numerical methods, we find that
