Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Perforation of welded aluminum extrusions

open access: yesEPJ Web of Conferences, 2015
A purely numerical procedure for predicting the perforation resistance of welded extruded AA6082-T6 aluminum profiles is presented in this study. The numerical work was conducted completely independent of the experimental tests that were only used for ...

Preventing wall deposition in duct flows: The role of particle number density and flow direction

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Particle deposition in wall‐bounded turbulent flows is a challenge in many industries, including pneumatic conveying, filtration, and related applications. When particles accumulate near boundaries, they reduce transport efficiency, alter near‐wall flow structures, and cause blockage.

Ultrafast Transitions in X‐Ray Irradiated Solids

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Effect of Polyurethane Colloid Content on the Ballistic Performance of Prepreg PBO Fiber Composite Laminates

open access: yesGaoya wuli xuebao
To address the issue of weak interfacial bonding and insufficient ballistic performance in poly-p-phenylene ben-zobisoxazole (PBO) fiber composites caused by the chemically inert fiber surface, the waterborne polyurethane impregnation followed by a hot ...

Overcoming spectral limits of perovskite photodetectors for the infrared region

open access: yesInfoScience, EarlyView.
Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...
