Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

Advanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.

Elderly Liver Grafts are More Susceptible to Ischemia‐Reperfusion After Prolonged Cold Ischemia than Grafts from Young Donors—An Ex Vivo Liver Machine Perfusion Analysis in Sprague Dawley Rats

Advanced Therapeutics, EarlyView.
This study investigates how donor age and cold ischemia time influence liver perfusion parameters and injury markers. Older livers are more susceptible to longer ischemia times displaying more tissue damage, and higher expression of oxidative stress and apoptosis‐related proteins than livers with shorter ischemia times.
