The spectral content of the myoelectric signals from the muscles of the remnant forearms of three persons with congenital absences (CA) of their forearms was compared with signals from their intact contra-lateral limbs, similar muscles in three persons with acquired losses (AL) and seven persons without absences [no loss (NL)]. The observed bandwidth for the CA subjects was broader with peak energy between 200 and 300 Hz. While the signals from the contra-lateral limbs and the AL and NL subjects was in the 100-150 Hz range. The mean skew of the signals from the AL subjects was 46.3 +/- 6.7 and those with NL of 45.4 +/- 8.7, while the signals from those with CAs had a skew of 11.0 +/- 11. The structure of the muscles of one CA subject was observed ultrasonically. The muscle showed greater disruption than normally developed muscles. It is speculated that the myographic signal reflects the structure of the muscle which has developed in a more disorganized manner as a result of the muscle not being stretched by other muscles across the missing distal joint, even in the muscles that are used regularly to control arm prostheses. 相似文献

The effective mobility of electrons μ* in the inversion n-type channel of a field-effect transistor increases appreciably (as a result of space-charge ion polarization of the gate oxide) from the typical values of ?820 cm2 V?1 s?1 to the values of ?2645 cm2 V?1 s?1, which exceed the electron mobility in bulk silicon. After polarization, the sheet concentration of Na+ ions at the SiO2/Si interface exceeds 6 × 1013 cm?2. The ions are almost completely neutralized by electrons in the inversion channel. As temperature T is decreased in the range from 293 to 203 K, μ* increases according to the law μ* ∝ T ?0.82. Apparently, the observed dependence μ*(T) is caused by the combined scattering of electrons by roughness of the Si/SiO2 interface surface, phonons, and the interface states. Depolarization of the oxide reverts μ* to the initial value. Anomalously large values of μ* are assumed to be either a consequence of the origination of pronounced structural stresses in the surface Si layer due to the oxide polarization or a result of a phase reconstruction of the inversion-channel region due to hybridization of the wave functions of electrons localized at the Na+ ions with the wave functions of electrons in the inversion channel. 相似文献

The total number of mobile ions in the oxide film in a Si-based MOS structure is determined by the conventional methods of
recording capacitance-voltage and dynamic current-voltage characteristics. The fraction of ions in the neutral state at the
Si-SiO2 interface is determined. Spectroscopy of the interface reveals a peak of the effective density of interface states. It is
shown that the number of states in this peak corresponds to the number of neutralized particles. The mechanism for neutralization
of the mobile charge of ions is discussed.

The paper discusses the method used by the CBC to a) ascertain that the quality of long-line transmissions is maintained at the required high level, and b) assist in the control of short-term deviations of transmission performance. It details the statistical approach employed in evaluating performance from data collected by regular sampling of key parameter values. The subjects of confidence levels and of user and supplier risks when evaluating performance are also discussed. 相似文献
