Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics
We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

Design and Experiment Analysis of a Direct-Drive Wave Energy Converter with a Linear Generator
Coastal waves are an abundant nonpolluting and renewable energy source. A wave energy converter (WEC) must be designed for efficient and steady operation in highly energetic ocean environments. A direct-drive wave energy conversion (D-DWEC) system with a

An Alien Word? Cosmic Salvation within a Rahnerian Framework
Abstract The possibility of life beyond our planet raises serious theological questions for Christians, particularly in the realm of soteriology. How would Jesus of Nazareth relate to such creatures? Is he the ‘universal’ saviour, in the cosmic sense? Or are there other incarnations of the Logos, the Word or Son of God?

Minimization of detent force in PMLSM by end magnetic regulating module with free topologies
In this paper, a novel method for suppressing the detent force of permanent magnet linear synchronous motors is proposed. First, the end force is adjusted to offset the cogging force while the cogging force remains unchanged.

ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

A Pull‐Out Mooring Wave Energy Converter: Design, Analysis, and Application
A pull‐out mooring wave energy converter (POM‐WEC) with a high‐performance electromagnetic power take‐off system efficiently converts low‐frequency wave excitation into high‐speed rotor motion, enabling reliable energy harvesting in real marine environments.
