3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

Control of Helix Screw‐Sense Preference in Dynamic Foldamers of meso Symmetry Built From Chiral Monomeric Units

Angewandte Chemie, EarlyView.
Sequence‐diverse meso and “near‐meso” oligourea foldamers are reported and exhibit stimulus‐responsive helix screw‐sense control governed by terminal‐group desymmetrization and sequence‐encoded helix stability. ABSTRACT Meso oligoureas are dynamic hydrogen‐bonded foldamers capable of reversible helix polarity inversion but have so far been limited to ...

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

AI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.
