recommendations! Published in 2024 at "Advanced Science"

DOI: 10.1002/advs.202402127

Abstract: Multi‐stable structures can be reconfigured with fewer, lightweight, and less accurate actuators. This is because the attraction domain in the multi‐stable energy landscape provides both reconfiguration guidance and shape accuracy. Additionally, such structures can generate… read more here.

recommendations! Published in 2017 at "Scientific Reports"

DOI: 10.1038/s41598-017-11355-1

Abstract: Some cardiovascular and non-cardiovascular drugs frequently cause excessive prolongation of the cardiac action potential (AP) and lead to the development of early afterdepolarisations (EADs), which trigger lethal ventricular arrhythmias. Combining computer simulations in APs with… read more here.
