    Respiratory sounds recorded for diagnostic purposes on the surface of the chest lie in the frequency range from 70-80 to 1000 Hz. The problem is ensuring sufficient efficiency of mechanico-acoustical conversion and undistortedness of the amplitude-frequency and phase-frequency characteristics of...

    Otoacoustic emissions are frequently acquired from patients in a variety of body positions aside from the standard, seated orientation. Yet little knowledge is available regarding whether these deviations will produce nonpathological changes to the clinical results obtained. The present study...

    The metal-oxide-semiconductor metamorphic high-electron-mobility transistor (MOS-MHEMT) with an oxide grown by liquid phase oxidation on the InGaAs capping layer without a gate recess exhibits a lower leakage current density with suppressed impact ionization, better microwave characteristics,...

  • Frequency response analysis of pentacene thin-film transistors with low impedance contact by interface molecular doping. Miyadera, Tetsuhiko; Minari, Takeo; Tsukagoshi, Kazuhito; Ito, Hiromi; Aoyagi, Yoshinobu // Applied Physics Letters;7/2/2007, Vol. 91 Issue 1, p013512 

    Frequency response measurements were performed on top-contact pentacene organic thin-film transistors (OTFTs). The ac characteristics of OTFTs are strongly limited by the contact interface between a metallic electrode and a pentacene thin film. Local doping of a charge transfer molecule (CTM)...
