Three dimensional printing of a low‐cost middle‐ear training model for surgical management of otosclerosis

Laryngoscope Investigative Otolaryngology, 2021
Background Surgical management of otosclerosis is technically challenging with studies demonstrating that outcomes are commensurate with surgical experience. Moreover, experts apply less force on the ossicular chain during prosthesis placement than their

Convergence of Plasmid‐Mediated tmexCD‐toprJ With Critical Resistance Genes Fuels Spread of Multidrug Resistant Bacteria

Advanced Science, EarlyView.
Global dissemination of tmexCD‐toprJ across bacterial hosts and ecological niches is accompanied by its convergence with blaKPC, blaNDM, and mcr on mobile plasmids. Recombination and acquisition of resistance modules generate distinct multidrug resistant plasmid architectures, facilitating the emergence and spread of high‐risk bacterial populations ...

High‐Pressure Modulation of Breathing Kagome Lattice: Cascade of Lifshitz Transitions and Evolution of the Electronic Structure

Advanced Science, EarlyView.
External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...

Anatomical, Histological, and Morphometrical Features of the Auditory Ossicles in Dog Fetuses at 55–56 Days of Gestation

Veterinary Sciences
This study examines the auditory ossicles of 55–56-day gestational age dog fetuses and shows that the basic three-bone middle ear pattern is already present, but the bones remain partly cartilaginous and are actively ossifying.

Time Resolved Reflectivity Measurements of Convective Clouds

Geophysical Research Letters, 2023
National Aeronautics and Space Administration's Investigations of Convective Updrafts (INCUS) mission aims to document convective mass flux through changes in the radar reflectivity (ΔZ) in convective cores captured by a constellation of three Ka‐band ...

Oxygen‐Driven Structural Reorganization by Trace Water Enabling Fast Li‐Ion Transport in a Pliable Solid Electrolyte

Advanced Energy Materials, EarlyView.
Trace water is acting as a constructive mediator in 2LiCl–GaF3, markedly increasing ionic conductivity while reorganizing local coordination. Hydration creates localized Li+ solvation environments and partially dissociates ion pairs, enhancing Li‐ion mobility.

Discovery of Novel Materials with Giant Dielectric Constants via First‐Principles Phonon Calculations and Machine Learning

Advanced Intelligent Discovery, EarlyView.
We discovered novel materials with giant dielectric constants by combining first‐principles phonon calculations and machine learning. Screening 525 perovskites identified six candidates. RbNbO3 was synthesized under pressure and showed ε ≈ 800–1000. This validates our framework as a powerful tool for high‐performance dielectric materials discovery.

Congenital Auditory Atresia and Malleus Incus Deformity [PDF]

External auditory canal atresia, or congenital auditory atresia, is a birth disease marked by underdevelopment of the external auditory canal. This condition frequently leads to abnormalities in the auricle and middle ear structures, and occasionally ...
