Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion
Advanced Robotics Research, EarlyView.This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

The gravitational-wave physics [PDF]
National Science Review, 2017 Abstract The direct detection of gravitational wave by Laser Interferometer Gravitational-Wave Observatory indicates the coming of the era of gravitational-wave astronomy and gravitational-wave cosmology. It is expected that more and more gravitational-wave events will be detected by currently existing and planned gravitational-wave ...

Exploring String Axions with Gravitational Waves
Galaxies, 2017 We explore the string axion dark matter with gravitational waves in Chern–Simons gravity. We show that the parametric resonance of gravitational waves occurs due to the axion coherent oscillation.

Light-cone distribution amplitudes of light mesons with QED effects
Journal of High Energy Physics, 2021 We discuss the generalization of the leading-twist light-cone distribution amplitude for light mesons including QED effects. This generalization was introduced to describe virtual collinear photon exchanges at the strong-interaction scale ΛQCD in the ...

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter
Advanced Robotics Research, EarlyView.A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.

Anatomy of non-leptonic two-body decays of charmed mesons into final states with η′
Journal of High Energy PhysicsWe show that D → Pη′ decay amplitudes, where P = K, π, η, cannot be simply related to their D → Pη counterparts with a single η 0–η 8 mixing angle. We propose a novel, consistent treatment of η 0–η 8 mixing for application in D → Pη and D → Pη′ decays ...
