No Correlation between Endo- and Exoskeletal Regenerative Capacities in Teleost Species
Fishes, 2019 The regeneration of paired appendages in certain fish and amphibian lineages is a well established and extensively studied regenerative phenomenon. The teleost fin is comprised of a proximal endoskeletal part (considered homologous to the Tetrapod limb ...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue
Advanced Science, EarlyView.This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...
