Incidence. The reported percentage of IARs during coiling varies among studies. A wide spectrum of IAR rates have been reported, and it is currently estimated to be between 1% and 5%. 2,3 Although procedural iatrogenic ruptures are more often seen with surgical clipping of aneurysms, IAR occurrence with coiling is associated with a higher …
Low-frequency broadband absorber with coherent coupling based …
Efficient broadband absorption of low-frequency sound via ultra-thin structure remains challenging due to the narrow-band property generated by the dispersive nature of resonance. In this study, we investigate the absorption mechanism of a component composed of a perforated panel and space-coiling channels through the coupling effect, …
