Cochlear implants [PDF]

open access: yesCurrent Biology, 2014
Cochlear implants are the first example of a neural prosthesis that can substitute a sensory organ: they bypass the malfunctioning auditory periphery of profoundly-deaf people to electrically stimulate their auditory nerve. The history of cochlear implants dates back to 1957, when Djourno and Eyriès managed, for the first time, to elicit sound ...

Pulse of inflammatory proteins in the pregnant uterus of European polecats (Mustela putorius) leading to the time of implantation [PDF]

open access: yes, 2017
Uterine secretory proteins protect the uterus and conceptuses against infection, facilitate implantation, control cellular damage resulting from implantation, and supply pre-implantation embryos with nutrients.

Functionalizing self-assembled GaN quantum dot superlattices by Eu-implantation [PDF]

open access: yes, 2010
Self-assembled GaN quantum dots (QDs) stacked in superlattices (SL) with AlN spacer layers were implanted with Europium ions to fluences of 1013, 1014, and 1015 cm−2.

Ion implantation and low-temperature epitaxial regrowth of GaAs [PDF]

open access: yes, 1981
Channeling and transmission electron microscopy have been used to investigate the parameters that govern the extent of damage in ion‐implanted GaAs and the crystal quality following capless furnace annealing at low temperature (∼400 °C). The implantation‐

Optical doping and damage formation in AIN by Eu implantation [PDF]

open access: yes, 2010
AlN films grown on sapphire were implanted with 300 keV Eu ions to fluences from 3×1014 to 1.4×1017 atoms/cm2 in two different geometries: “channeled” along the c-axis and “random” with a 10° angle between the ion beam and the surface normal.

Proton implanted sapphire planar and channel waveguides [PDF]

open access: yes, 2003
We report low-order transverse-mode planar waveguides in sapphire fabricated for the first time by proton implantation. The waveguides show good guiding properties without post-implantation annealing.

Pharmacokinetic analysis after implantation of everolimus-eluting self-expanding stents in the peripheral vasculature [PDF]

open access: yes, 2012
Background: A novel self-expanding drug-eluting stent was designed to release everolimus 225 mu g/cm(2) to prevent restenosis following peripheral arterial intervention.

The regulatory cliff edge between contraception and abortion: the legal and moral significance of implantation [PDF]

open access: yes, 2015
In regulating the voluntary interruption of pregnancy, English law has accorded particular significance to two biological events. First, ‘viability’, the moment when a fetus is said to acquire the capacity for independent life, plays an important role in

Implant Infection in Porous Orbital Implants

open access: yesOphthalmic Plastic & Reconstructive Surgery, 2006
To analyze implant infection in patients with porous orbital implants.A retrospective analysis of 212 patients with one of five types of porous orbital implants (bone-derived hydroxyapatite [HA], coralline HA, synthetic HA, porous polyethylene, and aluminium oxide) was conducted.

Silicon implantation in GaAs [PDF]

open access: yes, 1979
The electrical properties of room-temperature Si implants in GaAs have been studied. The implantations were done at 300 keV with doses ranging from 1.7×10^13 to 1.7×10^15 cm^–2.
