A Serial Mediation Model of Resilience Among Caregivers of Children With Autism.

Importance: Resilience has been reported as a vital element against the high burden on caregivers of children with autism. However, the intricate mechanisms underlying the concurrent interplay of positive factors with resilience within this demographic group remain less understood.

Objective: To construct a model to verify the sequential mediating influence of hope and gratitude in the relationship between perceived social support and resilience among caregivers of children with autism.

Analysis of Cushioned Landing Strategies of Cats Based on Posture Estimation.

This article addresses the challenge of minimizing landing impacts for legged space robots during on-orbit operations. Inspired by the agility of cats, we investigate the role of forelimbs in the landing process. By identifying the kinematic chain of the cat skeleton and tracking it using animal posture estimation, we derive the cushioning strategy that cats use to handle landing impacts.

Bionic Robot with Multifunctional Leg-Arm Mechanism for In-Orbit Assembly of Space Trusses.

This article aims to address the in-orbit assembly needs of truss structures in space missions by designing a robot capable of moving on trusses and manipulating parts. To enhance the stability of the robot during movement and part manipulation, inspiration was drawn from the Dynastes Hercules beetle. Building upon detailed research on the Dynastes Hercules beetle, a biomimetic structure was designed for the robot system.

The Discharge Behavior and Mechanism of Polyimide Aerogel under Electron Irradiation.

The response and mechanism of polyimide aerogel under electron irradiations were investigated. The experimental results indicated that electron irradiation could not damage the skeleton polyimide in the aerogel due to its high stability, but could result in a discharge within. The morphology of the discharge shows some dendritic discharge patterns, and the material surrounding the discharge channels was carbonized.

An Analytical Solution for Inverse Kinematics of SSRMS-Type Redundant Manipulators.

Compared with non-redundant manipulators, the self-motion of 7-DOF redundant manipulators results in an infinite number of inverse kinematics solutions for a desired end-effector pose. This paper proposes an efficient and accurate analytical solution for inverse kinematics of SSRMS-type redundant manipulators. This solution is applicable to SRS-type manipulators with the same configuration.

Robust Antibacterial Activity of Xanthan-Gum-Stabilized and Patterned CeO-TiO Antifog Films.

Increased occurrence of antimicrobial resistance leads to a huge burden on patients, the healthcare system, and society worldwide. Developing antimicrobial materials through doping rare-earth elements is a new strategy to overcome this challenge. To this end, we design antibacterial films containing CeO-TiO, xanthan gum, poly(acrylic acid), and hyaluronic acid.

Equivalent dynamic modeling of flexible morphing aircraft.

A morphing aircraft can maintain optimal flight performance by adaptively changing shape. However, large deformation and fast motion of aircraft modules lead to complicated dynamics during morphing process. This paper proposes a mechanistic equivalent model with parameters identified by optimization method.
