Lessons from Toy-Models for the Dynamics of Loop Quantum Gravity

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
We review some approaches to the Hamiltonian dynamics of (loop) quantum gravity, the main issues being the regularization of the Hamiltonian and the continuum limit.

A quantum reduction to spherical symmetry in loop quantum gravity

open access: yesPhysics Letters B, 2015
Based on a recent purely geometric construction of observables for the spatial diffeomorphism constraint, we propose two distinct quantum reductions to spherical symmetry within full 3+1-dimensional loop quantum gravity.

Loop-deformed Poincar\'e algebra

open access: yes, 2013
In this essay we present evidence suggesting that loop quantum gravity leads to deformation of the local Poincar\'e algebra within the limit of high energies.

Toward Autonomous Self‐Healing in Soft Robotics: A Review and Perspective for Future Research

open access: yesAdvanced 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 ...

Magnetic Fluid‐Driven Vine Robots for Minimally Invasive Tissue Biopsy Sampling

open access: yesAdvanced 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.
