A micromechanical study on the effects of precipitation on the mechanical properties of CoCrFeMnNi high entropy alloys with various annealing temperatures.

The CoCrFeMnNi high entropy alloys remain an active field over a decade owing to its excellent mechanical properties. However, the application of CoCrFeMnNi is limited because of the relatively low tensile strength. Here we proposed a micromechanical model which adopted from the theory of dislocation density to investigate the strengthening mechanisms of precipitation of chromium-rich non-equiatomic CoCrFeMnNi alloy.

Neutrophil-to-lymphocyte ratio in predicting neurologic outcome of patients with acute ischemic stroke treated with intravenous thrombolytics.

Background: Recombinant tissue plasminogen activator (rtPA) is currently the most standard treatment for patients with acute ischemic stroke (AIS). However, rtPA treatment may further enhance the immune response poststroke. This study is to investigate the clinical utility of white blood-based inflammatory biomarkers in predicting neurologic outcomes among AIS patients receiving rtPA.
