On the no-gravity limit of gravity [PDF]
arXiv, 2012 We argue that Relative Locality may arise in the no gravity $G\rightarrow0$ limit of gravity. In this limit gravity becomes a topological field theory of the BF type that, after coupling to particles, may effectively deform its dynamics. We briefly discuss another no gravity limit with a self dual ground state as well as the topological ultra strong $G\

Lattice Quantum Gravity from Stochastic 3-Geometries
, 1995 I propose the Langevin equation for 3-geometries in the Ashtekar's formalism to describe 4D Euclidean quantum gravity, in the sense that the corresponding Fokker-Planck hamiltonian recovers the hamiltonian in 4D quantum gravity exactly.

Inter‐Day Grasping Model Generalization for Prosthetic Hand Using Soft Optical Sensing Sleeve
Advanced Intelligent Systems, EarlyView.This article presents an optical sensing sleeve that addresses challenges in inter‐day grasping intent recognition caused by donning and doffing during repeated use. Featuring six specialized optical waveguides the sleeve accurately maps grasping forces with high generalization inter‐day and inner‐day.

Quantum gravity is a critical area of research aiming to reconcile the principles of general relativity and quantum mechanics. While general relativity explains the gravitational forces acting on massive bodies, it lacks compatibility with quantum mechanics, which governs the behavior of subatomic particles.

Journal of High Energy PhysicsAbstract We present the manifestly covariant canonical operator formalism of a Weyl invariant (or equivalently, a locally scale invariant) gravity whose classical action consists of the well-known conformal gravity and Weyl invariant scalar-tensor gravity, on the basis of the Becchi-Rouet-Stora-Tyupin (BRST) formalism.

Bioinspired Moisture‐Driven Soft Robotic Actuator
Advanced Intelligent Systems, EarlyView.In response to the evolving field of robotics, the demand for soft actuator materials has surged, prompting a shift toward biomimetic models, notably plant‐based actuators. The Arundo donax species exemplifies a unique hinged single‐unit actuation system and a combined mechanism utilizing atmospheric water content, offering multifunctional capabilities.
