Early universe in quantum gravity

open access: yesJournal of High Energy Physics
We present a new picture of the early universe in finite nonlocal quantum gravity, which is Weyl invariant at the classical and quantum levels. The high-energy regime of the theory consists of two phases, a Weyl invariant trans-Planckian phase and a post-

A Novel Parameter Estimation Method for Pneumatic Soft Hand Control Applying Logarithmic Decrement for Pseudo‐Rigid Body Modeling

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
In this research, a paradigm of parameter estimation method for pneumatic soft hand control is proposed. The method includes the following: 1) sampling harmonic damping waves, 2) applying pseudo‐rigid body modeling and the logarithmic decrement method, and 3) deriving position and force control.

The cosmological impact of Brane-Chern-Simons massive gravity

open access: yesJournal of High Energy Physics
In this paper, we present a novel extension of massive gravity theory; the Brane-Chern-Simons massive gravity theory. We explore the cosmological implications of this theory by deriving the background equations and demonstrating the existence of self ...

Robotic Environmental Monitoring Using Gelatin Hydrogels as a Biodegradable Adhesive

open access: yesAdvanced Intelligent Systems, EarlyView.
Gelatin‐based hydrogels are presented as a robust, biodegradable, and water‐soluble method of adhesion for robotic environmental monitoring. Factors affecting the adhesion strength are characterized, and the hydrogel is tested on different materials with varying surface roughness.

The Adaptive Trajectory of the Normal Force Vector in the Polishing of Curved Surface Component Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This study uses iterative learning control and voice coil motor to keep normal force constant in curved surface polishing. A mechanism‐data fusion model adjusts robotic posture via real‐time feedback for adaptive tracking control of normal force vector direction.

Strict renormalizability as a paradigm for fundamental physics

open access: yesJournal of High Energy Physics
An important theoretical achievement of the last century was the realization that strict renormalizability can be a powerful criterion to select Lagrangians in the framework of perturbative quantum field theory.

Ultrafast Untethered Levitation Device Utilized Squeeze Film for Omni‐Directional Transport

open access: yesAdvanced Intelligent Systems, EarlyView.
Untethered levitation device (106 g, 95 × 72 × 45 mm3) on squeeze film is generated by a piezoelectric actuator with onboard electronics (77 g). It achieves frictionless and omnidirectional movement over 1.4 and 3.0 ms−1 on horizontal and inclined surfaces respectively.
