BeeRootBot: A Bioinspired Robotic Probe Exhibiting Apical Growth through In Situ Soil Binding
Advanced Intelligent Systems, EarlyView.This study introduces a novel method for consolidating subterranean exploration pathways in plant‐inspired robots by binding in‐situ soil with beeswax, a biobased material. This simultaneous advancement and wall‐lining process reduces penetration resistance, enhances exploration efficiency, enables communication and resource sharing, and promotes ...

Intersecting Quantum Gravity with Noncommutative Geometry - a Review
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We review applications of noncommutative geometry in canonical quantum gravity. First, we show that the framework of loop quantum gravity includes natural noncommutative structures which have, hitherto, not been explored.

REWW‐ARM—Remote Wire‐Driven Mobile Robot: Design, Control, and Experimental Validation
Advanced Intelligent Systems, EarlyView.The Remote Wire‐Driven robot “REWW‐ARM” demonstrates a new concept of remote actuation that separates electronics from harsh environments while retaining closed‐loop control. Combining tendon‐sheath mechanisms with decoupled joints, it achieves efficient power transmission and autonomous locomotion, manipulation, and underwater operation, suggesting ...

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

Quantum phenomenological gravitational dynamics: a general view from thermodynamics of spacetime
Journal of High Energy Physics, 2020 In this work we derive general quantum phenomenological equations of gravitational dynamics and analyse its features. The derivation uses the formalism developed in thermodynamics of spacetime and introduces low energy quantum gravity modifications to it.

Black Hole Evolution Traced Out with Loop Quantum Gravity
Physics, 2018 Loop quantum gravity—a theory that extends general relativity by quantizing spacetime—predicts that black holes evolve into white holes.

Modeling and Characterization of a Self‐Sensing Soft Hydraulic Muscle
Advanced Intelligent Systems, EarlyView.This article presents the self‐sensing soft hydraulic muscle (SSHM), a novel soft actuator capable of simultaneously sensing force and length without external sensors. A comprehensive model accurately predicts SSHM behavior, validated experimentally with minimal errors. Using propylene glycol enhances durability and reduces hysteresis.

Entanglement entropy in loop quantum gravity [PDF]
Physical Review D, 2008 The entanglement entropy between quantum fields inside and outside a black hole horizon is a promising candidate for the microscopic origin of black hole entropy. We show that the entanglement entropy may be defined in loop quantum gravity, and compute its value for spin network states.

Annalen der Physik, EarlyView.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Effects of underlying topology on quantum state discrimination
European Physical Journal C: Particles and FieldsIn this work, we show that quantum state discrimination can be modified due to a change in the underlying topology of a system. In particular, we explicitly demonstrate that the quantum state discrimination of systems with underlying discrete topology ...
