Dynamic Obstacle Avoidance of Metamorphic Microrobots Using Concentric Sector Navigator

Advanced Intelligent Systems, EarlyView.
Metamorphic magnetic microrobots are navigated using a concentric sector navigator for dynamic obstacle avoidance in both microroller and swarm states. After microroller transport, citrate‐triggered dissolution releases nanoparticles that reassemble into a controllable swarm.

Accurate depth from defocus estimation with video-rate implementation [PDF]

The science of measuring depth from images at video rate using „defocus‟ has been investigated. The method required two differently focussed images acquired from a single view point using a single camera.

Curve complexes are rigid [PDF]

, 2011
Any quasi-isometry of the curve complex is bounded distance from a simplicial automorphism. As a consequence, the quasi-isometry type of the curve complex determines the homeomorphism type of the ...

Anion‐Selective Channels Formed by Synthetic 13‐Mer Chimeric α ‐Peptide‐Oligourea Foldamers

Chemistry – A European Journal, EarlyView.
Synthetic 13‐mer α‐peptide‐oligourea chimeric foldamers self‐assemble into supramolecular ion channels, demonstrating high ion transport activity with distinct anion selectivity in lipid membranes. This study supports the design of bioinspired functional foldamer‐based channels for synthetic ion transport applications.

Artificial Intelligence in Optical Coherence Tomography‐Based Ophthalmic Imaging: From Automated Diagnosis to Personalized Disease Monitoring

Eye &ENT Research, EarlyView.
ABSTRACT Artificial intelligence (AI) is increasingly applied to optical coherence tomography (OCT) in ophthalmology, but evidence for automated diagnosis is stronger than evidence for longitudinal monitoring. This narrative review evaluates OCT‐based AI with emphasis on disease monitoring and progression, particularly in retinal disease and glaucoma ...
