Influence of taper design and loading on taper micromotion

open access: yesJournal of the Mechanical Behavior of Biomedical Materials, 2022
Debris originating at the bore-trunnion interface of modular total hip replacements has been identified as one of the causes of hip replacements failure. Friction associated with fretting and corrosion represents a potential generator of these harmful particles.

Not all cemented hips are the same: a register-based (NJR) comparison of taper-slip and composite beam femoral stems

open access: yesActa Orthopaedica, 2019
Background and purpose — No difference in outcome has been demonstrated comparing cemented taper-slip and composite beam designs in short-term randomised trials; we assessed outcome differences using a registry analysis.

Coupled fiber taper extraction of 1.53 um photoluminescence from erbium doped silicon nitride photonic crystal cavities [PDF]

open access: yes, 2010
Optical fiber tapers are used to collect photoluminescence emission at ~1.5 um from photonic crystal cavities fabricated in erbium doped silicon nitride on silicon. Photoluminescence collection via fiber taper is enhanced 2.5 times relative to free space,
