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 ...

Innovative PLA or PCL‐Based Ocular Implants Obtained From Tape Casting or Electrospinning for Sustained‐Release Dexamethasone

Journal of Applied Polymer Science, EarlyView.
PLA and PCL ocular implants prepared by tape casting and electrospinning provide sustained dexamethasone release with distinct release profiles governed by polymer type and processing method. The relationship between polymer structure, degradation behavior, and drug release demonstrates the potential of these fabrication techniques for controlled ...

Emergency management: vitreous loss [PDF]

, 2018
The most common mistake when managing vitreous loss is to leave some of it behind in the anterior chamber or up to the wound. Knowing when to stop using the vitrector, and how to tell whether there is any vitreous remaining, is ...

Identification and correlation of the Aso‐3 tephra in the Omaezaki area, central Japan: A valuable key stratum for the MIS 6/5 transition period

Journal of Quaternary Science, Volume 41, Issue 6, Page 972-986, August 2026.
ABSTRACT The Aso‐3 tephra is one of the most significant widespread marker layers from the Middle to Late Pleistocene, generated by a large caldera‐forming eruption at the Aso volcano in Kyushu, southwestern Japan. Despite its importance, a distal co‐ignimbrite ash correlative has yet to be clearly identified, primarily because although volcanic glass ...
