Advanced Physics Research, EarlyView., 2023 The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Advanced Intelligent Systems, EarlyView.A polydopamine (PDA)‐assisted electroless deposition method enables the solution‐based conformal coating of 3D‐printed microstructures with superparamagnetic nickel thin films. This multilayer magnetic coating is implemented and demonstrated in three magnetic microrobot archetypes, including arbitrarily shaped active particles, microrollers, and ...

Deep Q‐Network‐Based Hierarchical Path Planning of a Biped Wall‐Climbing Robot for Window Cleaning
Advanced Intelligent Systems, EarlyView.This article presents a biped wall‐cleaning climbing robotic system for the maintenance of multi‐isolated areas on exoskeleton‐structured windows (ESWs). A full coverage cleaning approach is proposed by integrating a deep Q‐network‐based method with the robotic system to address the complete coverage cleaning path planning problem.

On the lithium abundance of the visual binary components ξ Boo A (G8V) and ξ Boo B (K5V)
Astronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022 Abstract A spectroscopic investigation of the lithium resonance doublet in ξ Boo A and ξ Boo B in terms of both abundance and isotopic ratio is presented. We obtained new R = 130,000 spectra with a signal‐to‐noise ratio (S/N) per pixel of up to 3200 using the 11.8 m LBT and PEPSI.

Toward Autonomous Self‐Healing in Soft Robotics: A Review and Perspective for Future Research
Advanced Intelligent Systems, EarlyView.In this article, five different phases (damage detection, cleaning, damage closure, material healing, and healing assessment) are investigated to have an autonomous self‐healing at the system level with the focus on soft robotics. It delves into the importance of each phase, why and where they matter, and reviews relevant technologies that enable ...
