Implications for Lunar Crustal Evolution from Y-86032 and Dho 908 [PDF]
, 2010 We have studied anorthositic clasts in the Y-86032 and Dhofar 908 meteorites by the Rb-Sr, Sm-Nd, and Ar-39-Ar-40 techniques combining isotopic studies with mineralogical/petrological studies of the same clasts.

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Semi‐autonomous Navigation of Magnetic Microcarriers for Knee Cartilage Regeneration
Advanced Intelligent Systems, EarlyView.Autonomous navigation of magnetic microcarriers in complex 3D environments is investigated through a semi‐autonomous strategy integrating magnetic actuation with monocular visual feedback. Real‐time global tracking is achieved via radio‐frequency‐based localization and depth estimation, while model‐based computation determines optimal steering forces ...

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT RASopathies are clinically overlapping neurodevelopmental syndromes resulting from germline mutations in genes involved in the rat sarcoma/mitogen‐activated protein kinases (RAS/MAPK) pathway. Historically, RASopathies have been described by clinical phenotypes, such as Noonan syndrome and Neurofibromatosis type I.
