Background: Debate continues as to whether patients with acute ischemic stroke with (suspected) large vessel occlusion benefit from direct referral versus secondary transportation.
Aims: To analyze the change in early infarct signs, collaterals, and acute ischemia volume and their association with transfer time and functional outcome.
Methods: We retrospectively analyzed consecutive transfers between 2013 and 2016 for patients with anterior circulation stroke transported from referring hospitals to our center as potential candidates for thrombectomy.
Article Synopsis
- Metallic glasses have a special way of bending called shear bands, and these are really important for how they break or change shape.
- Scientists are studying new types of metallic glasses with tiny glass bubbles to understand how these shear bands form and change.
- They found that when shear bands happen, the tiny glass bubbles inside dissolve, while those nearby grow bigger, and the area around the shear bands also gets affected, which makes the material behave differently.
The polyamorphsim in amorphous materials is one of the most fascinating topics in condensed matter physics. In amorphous metals, the nature of polyamorphic transformation is poorly understood. Here we investigate the structural evolution of a Ce-based metallic glass (MG) with pressure at room temperature (RT) and near the glass transition temperature by synchrotron X-ray diffraction, uncovering novel behaviours.
