Ketamine’s impact on rumination-related brain dynamics: insights from a randomized controlled fMRI trial

Abstract Rumination has been associated with aberrant dynamics of a coactivation pattern (CAP) comprising the default mode (DMN) and frontoparietal (FPN) networks. Ketamine exerts rapid antidepressant effects and may influence these dynamics via glutamatergic mechanisms. In a ran...

Effect of sizing materials on corrosion resistance of basalt fibers in various exposure environments

This study investigated the influence of sizing materials on the corrosion resistance of basalt fibers exposed to 16 controlled environments combining pH 4–13 and salinity from 0 to 20,000 ppm as chloride. Fibers were exposed to 60°C for 600 days in an environmental chamber, and...
