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 ...

Horizon entropy with loop quantum gravity methods
Physics Letters B, 2015 We show that the spherically symmetric isolated horizon can be described in terms of an SU(2) connection and an su(2)-valued one-form, obeying certain constraints.

Design and Analysis for a Diving‐Beetle‐Inspired Swimming Robot with Multi‐Flexible Appendages
Advanced Intelligent Systems, EarlyView.This article presents a bionic underwater robot inspired by the swimming behavior of diving beetles. The robot features flexible appendages and a specialized motion controller to mimic the beetle's swimming gaits. Extensive experiments show improved thrust, speed, and maneuverability.

The cosmological constant problem and the effective potential of a gravity-coupled scalar
Journal of High Energy PhysicsWe consider a quantum scalar field in a classical (Euclidean) De Sitter background, whose radius is fixed dynamically by Einstein’s equations. In the case of a free scalar, it has been shown by Becker and Reuter that if one regulates the quantum ...

This paper presents a novel Quantum Gravity Theory (QGT) that reinterprets the gravitational field as being derived from the Higgs field within a flat spacetime framework. Unlike General Relativity (GR), which attributes gravity to spacetime curvature, QGT integrates quantum corrections, nonlinear dynamics, and a variable speed of lightto describe ...

Magnetic Fluid‐Driven Vine Robots for Minimally Invasive Tissue Biopsy Sampling
Advanced Intelligent Systems, EarlyView.This study introduces a magnetic fluid‐powered vine robot for minimally invasive biopsies. The robot uses fluid pressurization for locomotion and external magnetic fields for precise steering. Its soft structure and high magnetic volume ensure controlled movements and stabilization, enabling effective tissue penetration.
