Hydrogen/deuterium was implanted in ^100& silicon to passivate dangling bonds at the Si/SiO2 interface when a thin oxide is grown on implanted silicon substrate. It was observed that implantation energy and dose influence the interface passivation. Measured interface states at the Si/SiO2 interface suggest an isotope effect where deuterium implanted devices yielded better interface passivation ...

BACKGROUND New approaches for non-invasive embryo-quality assessment are among the major goals in Reproductive Medicine. We hypothesize that the detection of changes in the protein profile of the culture media in which blastocysts are cultured could be a potential indicator of the viability of the embryo and, thus, a useful tool for selecting the more appropriate blastocysts to be transferred. ...

This study revisits the issue of the spectral ripple resolution abilities of cochlear implant (CI) users. The spectral ripple resolution of recently implanted CI recipients (implanted during the last 10 years) were compared to those of CI recipients implanted 15 to 20 years ago, as well as those of normal-hearing and hearing-impaired listeners from previously published data from Henry, Turner, ...

Measuring with a spectroscopic ellipsometer (SE) in the 1.845 eV photon energy region we determined the complex dielectric function (E = e1 + ieZ> of different kinds of amorphous silicon prepared by self-implantation and thermal relaxation (500 “C, 3 h) . These measurements show that the complex dielectric function (and thus the complex refractive index) of implanted a-Si (i-a-Si) differs from ...

We investigated THz emission from Ar-ion-implanted Cu(In,Ga)Se2 (CIGS) films. radiation the CIGS films increases as density of implanted Ar ions increases. This is because contribute to an increase in surface surge current density. The effect Ar-ion implantation on carrier dynamics was also using optical pump probe spectroscopy. fitted results imply that charge transition intra-and carrier–carr...

OBJECTIVES In this study, we looked at the effect of hypercapnia on sleep architecture and breathing. We characterized the effect of hypercapnia on duration, frequency, and latency of NREM and REM sleep. We described state-specific patterns of breathing as well. This study is relevant to understand possible treatments for sleep disordered breathing. METHODS Four cats were studied during 3-hou...

The use of chronically implanted electrodes for neural recordings in small, freely behaving animals poses several unique technical challenges. Because of the need for an extremely lightweight apparatus, chronic recording technology has been limited to manually operated microdrives, despite the advantage of motorized manipulators for positioning electrodes. Here we describe a motorized, miniatur...

Multiple neuronal activity, recorded through chronically implanted electrodes, was analyzed. During acquisition and consolidation of alimentary conditioned reflexes to electrostimulation of the lateral geniculate body or optical tract, the patterns of neuronal activity in the visual cortex and sensory motor cortex became organized in a way different from that observed during pseudoconditioning....

Functional electrical stimulation (FES) involves artificial activation of muscles with implanted electrodes to restore motor function in paralyzed individuals. The range of motor behaviors that can be generated by FES, however, is limited to a small set of preprogrammed movements such as hand grasp and release. A broader range of movements has not been implemented because of the substantial dif...
