Background: Distal femoral fractures are not common among all fractures and the incidence rises with age.While this kind of Dome Cameras fracture is usually caused by low-energy trauma in the elderly, there are many known fracture patterns.We encountered a new pattern of fracture in a middle-aged man.Case Presentation: A 56-year-old obese man prese
To investigate the damage evolution and failure mechanisms of fiber-reinforced composite materials under complex conditions, this study conducted in situ X-ray computed tomography (CT) compression and tensile tests on plain weave two-dimensional woven SiC/SiC composite materials.The obtained CT in situ image data captured the behavior of materials
Prior studies of Mesozoic biodiversity document a diversity peak for dinosaur species in the Campanian stage of the Late Cretaceous, yet have failed to provide explicit causal mechanisms.We provide evidence that a marked increase in North American dinosaur biodiversity can be attributed to dynamic orogenic episodes within the Western Interior Basin
Glass-forming liquids are broadly classified as being fragile or strong, depending on the deviation from Arrhenius behavior of their relaxation times.A fragile to strong crossover is observed or inferred in liquids like water and silica, and more recently also in metallic glasses and phase change alloys, leading to the expectation that such a cross
