Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

Journal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

A rare presentation of a middle ear osteoma of the incus case report

Acta Oto-Laryngologica Case Reports
Middle ear osteoid osteomas are rare, and they can be misdiagnosed as otosclerosis. Conductive hearing loss, aural fullness, tinnitus and rarely otorrhoea are presenting symptoms. A rare paediatric case is highlighted here.

A method to measure sound transmission via the malleus-incus complex [PDF]

, 2016
BACKGROUND: The malleus-incus complex (MIC) plays a crucial role in the hearing process as it transforms and transmits acoustically-induced motion of the tympanic membrane, through the stapes, into the inner-ear. However, the transfer function of the MIC

Integrating Augmented Reality Into Otologic Cadaveric Surgical Training

The Laryngoscope, EarlyView.
This pilot study developed and implemented a specimen‐specific augmented reality (AR) workflow for cadaveric temporal bone dissection, using CT‐derived 3D models registered to each specimen and viewed intermittently through a Microsoft HoloLens 2 headset.

Interaction of restoration processes with properties within copper‐graphene composites during direct consolidation Interaktion von Wiederherstellungsprozessen mit Eigenschaften innerhalb von Kupfer‐Graphen‐Verbundwerkstoffen während der direkten Konsolidierung

Materialwissenschaft und Werkstofftechnik, EarlyView.
By refining grains and additions of strengthening elements, mechanical properties of electro‐conductive copper can be increased. Fine‐grained coper‐graphene composites were directly consolidated from original powders by rotary swaging to achieve rods with enhanced mechanical properties and electric conductivity of up to 96% international annealed ...

Statistical shape analysis of the incus

Folia Morphologica
BACKGROUND: The incus is one of the three auditory ossicles involved in the conductive process of audition. The incus is often a target in otologic procedures, which have high revision and failure rates. Foundational knowledge of the incus’ morphological

Optimizing Na and Rb Incorporation Along With Bandgap Grading for High Efficiency Ultra‐Thin CIGSe Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
In this work, Na and Rb are incorporated into ultra‐thin Cu(In,Ga)Se2 (< 500 nm). By systematically varying the Rb content and combining predeposited Na with postdeposited Rb, we identify the optimal configuration, achieving solar cell efficiencies of 11.72% on Mo and 10.48% on ITO. Through electrical and compositional measurements, a mechanistic model

Stop Using Limiting Stimuli as a Measure of Sensitivities of Energetic Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Accurately estimating the sensitivity of explosive materials is a potentially life‐saving task that requires standardised protocols across nations. One of the most widely applied procedures worldwide is the so‐called ‘1‐In‐6’ test from the United Nations (UN) Manual of Tests in Criteria, which estimates a ‘limiting stimulus’ for a material. In

Stapes Surgery: How Precisely Do Different Prostheses Attach to the Long Process of the Incus with Different Instruments and Different Surgeons?

, 2002
Hypothesis: The goal of this study was to compare the attachment of stapes prostheses with differently shaped loop, to the long process of the incus. Background: In stapes surgery, the attachment of the prosthesis to the long process of the incus plays ...
