Although it is generally recognized that the long-term clinical outcome of bare-metal stents (BMS) is favorable, a late luminal narrowing with restenosis of BMS can occur during the extended follow-up (beyond 5 years), resulting in clinical events such as stent thrombosis and myocardial infarction. Regarding the mechanisms of progressive late luminal renarrowing, a persistent and remarkable for...

Damage from ion implantation in Si can lead to dislocation formation during subsequent thermal annealing. These dislocations may sharply degrade device performance, making it desireable to suppress their formation. In this paper the criterion for dislocation formation is reviewed. Knowing this criterion suggests several ways to avoid dislocation formation in high dose implants for device applic...

objectives: this study examined the relationship between working and short-term memory performance, and their effects on cochlear implant outcomes (speech perception and speech production) in cochlear implanted children aged 7-13 years. the study also compared the memory performance of cochlear implanted children with their normal hearing peers. methods: thirty-one cochlear implanted children w...
