International Journal of Modern Physics D, 2007 We present the current status of the new approach to quantum general relativity based on the exact resummation of its perturbative series as this series was formulated by Feynman. We show that the resummed theory is UV-finite and we present some phenomenological applications as well.

Smooth Quantum Gravity: Exotic Smoothness and Quantum Gravity [PDF]
, 2016 Over the last two decades, many unexpected relations between exotic smoothness, e.g. exotic $\mathbb{R}^{4}$, and quantum field theory were found. Some of these relations are rooted in a relation to superstring theory and quantum gravity. Therefore one would expect that exotic smoothness is directly related to the quantization of general relativity. In

Advanced Intelligent Systems, EarlyView.To tackle the challenge of parameter estimation in dynamic human–robot interaction, this research proposes a novel method that integrates a disturbance observer with Kalman filtering. In contrast to conventional techniques, this approach facilitates the simultaneous real‐time estimation of human wrench and object parameters, offering significantly ...

Advanced Intelligent Systems, EarlyView.Single‐pump‐actuated transformable dual‐mode gripper (SATDG) that combines vacuum suction and granular jamming to effectively grasp objects ranging from 10 to 300 mm in size, spanning a vast 30‐fold range, with forces from 0.5 to 21 N, is studied. Using a bistable mechanism and origami structure, the SATDG can transform between two modes and activate ...

Quantum Riemannian Geometry and Black Holes
, 2006 Black Holes have always played a central role in investigations of quantum gravity. This includes both conceptual issues such as the role of classical singularities and information loss, and technical ones to probe the consistency of candidate theories ...

Modular Stimuli‐Responsive Valves for Pneumatic Soft Robots
Advanced Intelligent Systems, EarlyView.Modular stimuli‐responsive valves, based on responsive materials (i.e., liquid crystal elastomers and hydrogels) and mechanical mechanisms, can autonomously regulate airflow in the presence of multiple environmental stimuli, such as light and water.

Cosmological effective Hamiltonian from full loop quantum gravity dynamics
Physics Letters B, 2018 The concept of effective dynamics has proven successful in LQC, a loop-inspired quantization of cosmological spacetimes. We apply the same idea of its derivation in LQC to the full theory, by computing the expectation value of the scalar constraint with ...
