    Notes: Abstract Extracellular recordings were made from the nucleus ambiguus in three conscious Macaca nemestrina monkeys during spontaneous vocalizations and swallows. The temporal relationship of neuronal activity to swallowing was inferred through correlation with the thyroarytenoid electromyographic (EMG) activity. Videofluoroscopic analysis of a fourth monkey during swallows of barium-impregnated fruit juice established the temporal relationship between swallowing and thyroarytenoid EMG activity. Of 691 cells recorded from the nucleus ambiguus and its adjacent area, the neuronal activity of 80 cells showed modulation during swallowing. Sixty-two cells were classified as “active” cells, with increased activity in relation to swallowing, while 18 cells were classified as “suppressed” cells, with tonic activity that reduced with swallowing. A continuum of latency was seen between the onset of modulation of these cells and the onset of swallowing, from “early” before the swallow to “late” after the swallow onset with most of the cells (44 cells) showing modulation near the onset of the swallow. A majority (37) of the 62 active swallowing-related cells also discharged with vocalization, but they demonstrated a lower discharge frequency and a longer burst duration during swallowing. Of the 18 suppressed swallowing-related cells, 11 cells discharged phasically with the respiratory cycle and may be a part of the ventral medullary respiratory center. This chronic awake primate model would preserve the many sensory inputs that may modify the oropharyngeal swallow and may better approximate human physiology.

    Notes: The electrical properties and integrity of oxides grown on textured single-crystal silicon (TSC oxides) are investigated and are compared to oxides grown on untextured single-crystal silicon (normal oxides) and oxides grown on polycrystalline silicon (polyoxides). The 230 A(ring) TSC oxide exhibited enhanced electron injection in both polarities, reducing the voltage necessary for JG=+1 mA/cm2 from 21 V for normal 230 A(ring) oxides to 5 V. This made the 230 A(ring) TSC oxide approximately equivalent to a 60 A(ring) normal oxide. The electron trapping rate for the TSC oxide was similar to that of 230 A(ring) normal oxides but is much smaller than that of polyoxides. Charge-to-breakdown (QBD) measurements showed a much better QBD histogram (large area capacitors) for the TSC oxide than for 230 A(ring) and 60 A(ring) normal oxides.

    Notes: The effects of nitridation and reoxidation on the off-state leakage currents of n-channel metal-oxide-semiconductor-field-effect transistors have been investigated. It is found that nitridation greatly increases the gate leakage in the low-field range but ensuing reoxidation can effectively reduce it. Nitridation-induced oxide traps could be responsible for this leakage, along with traps introduced during the source/drain implant. A trap-assisted tunneling model has been proposed to explain this off-state gate leakage.

    Notes: Abstract. We consider the gluino-mediated SUSY contributions to B0 - $ \overline{B^0}$ mixing, $B\rightarrow J/\psi K_s$ and $B\rightarrow X_d \gamma$ in the mass insertion approximation. We find that the (LL) mixing parameter can be as large as $\vert (\delta_{13}^d)_{\mathrm {{LL}}} \vert \lesssim 2 \times 10^{-1}$ , but the (LR) mixing is strongly constrained by the $B\rightarrow X_d \gamma$ branching ratio and we find $\vert (\delta_{13}^d)_{\mathrm {{LR}}} \vert \lesssim 10^{-2}$ . The implications for the direct CP asymmetry in $B\rightarrow X_d \gamma$ and the dilepton charge asymmetry (All) are also discussed, where substantial deviations from the standard model (SM) predictions are possible.
