A Soft Wearable Robot with an Adjustable Twisted String Actuator and a Two‐Stage Transmission Mechanism for Manual Handling Tasks

open access: yesAdvanced Intelligent Systems, EarlyView.
This article proposes a soft wearable robot (WeaRo) to assist workers while executing manual handling tasks. With its innovative design, the WeaRo effectively assists multiple body parts during manual handling tasks while using a single motor. Furthermore, the components of the WeaRo are assembled onto a fabric‐based suit, ensuring high performance and

Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

open access: yesAdvanced 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.

Polydopamine‐Assisted Electroless Deposition of Magnetic Functional Coatings for 3D‐Printed Microrobots

open access: yesAdvanced 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 ...

Theory Of Quantum Gravity

open access: yes, 2019
Basically this theory has been developed to propose an oscillating universe. According to my theory, the matter is the only origin of gravity. In this theory all fundamental physical entities such as space, time, matter, force, energy and others are used in their usual meanings as in classical mechanics. The space and time are not related to each other.

Deep Q‐Network‐Based Hierarchical Path Planning of a Biped Wall‐Climbing Robot for Window Cleaning

open access: yesAdvanced 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)

open access: yesAstronomische 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.
