Effect of Case Variation on Mastoidectomy Training Using 3D‐Printed Temporal Bones Models—A Prospective, Randomized Trial

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To investigate effects of repeated training with anatomically varied versus identical 3D‐printed models on skill acquisition, cognitive load, and skill retention in novice mastoidectomy trainees. Study Design A prospective, randomized, controlled, educational trial conducted April to September 2024 including a 3‐month retention test.

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

Relationship between pathologies of bone chain and middle ear mucosa in chronic otitis media

Turkish Archives of Otorhinolaryngology, 2010
Objectives: Chronic otitis media is an inflammatory process which causes tympanic membrane perforation, destruction of middle ear structure and loss of hearing. Most effected structure in this process is hearing bones.

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

Evaluation of the Effectiveness of Incus Interposition in the Geriatric Population

B-ENT
Background: Hearing loss reduces quality of life, particularly prevalent in the geriatric population (≥ 65 years). This study aims to evaluate the efficacy of incus interposition in the geriatric population and to compare functional outcomes with those ...

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

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Characteristics of upper‐level updrafts and downdrafts in the anvils of tropical deep convective clouds

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.
