Statistical Morphology and Fragment Mapping of Complex Proximal Humeral Fractures

Medicina, 2023
Background and Objectives: Proximal humerus fractures (PHFs) are common in the elderly, but the treatment results are often poor. A clear understanding of fracture morphology and distribution of cortical bone loss is important for improved surgical ...

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

Advanced Engineering Materials, EarlyView.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

Fracture morphology and viscous transport [PDF]

International Journal of Rock Mechanics and Mining Sciences, 2008
Abstract The morphology of a fracture in a granite block is sampled using a high resolution profiler providing a 3999 × 4000 pixel image of the roughness. We checked that a self-affine model is an accurate geometrical model of the fracture morphology on the basis of a spectral analysis.

Classification and pathoanatomy of posterior malleolus fracture based on posterior malleolus-associated ligaments and ankle stability

Journal of Orthopaedic Translation
Background: The clinical significance of previous posterior malleolus fracture classifications is limited because they are mainly based on fracture morphology. On the basis of posterior malleolus-associated ligaments and ankle stability, injury mechanism,
