Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

open access: yesAdvanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

ANTIHISTAMINASE ACTIVITY OF SERPENTINE [PDF]

open access: yesBritish Journal of Pharmacology and Chemotherapy, 1961
Serpentine, an alkaloid of Rauwolfia serpentina, specifically potentiates histamine responses of guinea‐pig ileum, uterus, and tracheal chain. It also inhibits histaminase in vitro. Its antihistaminase activity is equivalent to that of aminoguanidine.
