Research on the Nonlinear Structural Dynamic Characteristics of the Rigid Flexible Coupling Folding Wing Model for Aircraft

Engineered Science
During the working process of the folding wing, there is not only a large-range rigid body motion but also a deformation motion of the flexible components. The problem of the rigid-flexible coupling of the structure is extremely complex.

A bioinspired fishbone continuum robot with rigid-flexible-soft coupling structure

Bioinspiration & Biomimetics, 2022
Abstract Rigid-flexible-soft coupled robots are an important development direction of robotics, which face many theoretical and technical challenges in their design, manufacture, and modeling. Inspired by fishbones, we propose a novel cable-driven single-backbone continuum robot which has a compact structure, is lightweight, and has ...

Virtual Simulation Analysis of Rigid‐Flexible Coupling Dynamics of Shearer with Clearance [PDF]

Shock and Vibration, 2018
A model for virtual simulation analysis of the rigid‐flexible coupling of a shearer has been developed with the objective of addressing problems associated with lifetime mismatch and low reliability of pin rows of a scraper conveyor and the corresponding support mechanism of a shearer.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Research on Dynamic Characteristics of Rigid-Flexible Coupling System

Journal of Physics: Conference Series, 2019
Abstract In order to study the influence of a flexible component on the vibration of a rigid-flexible coupling system under a shooting condition, the finite element theory is used to calculate the modal of the flexible component and establish its rigid region. The dynamic theory is used to establish the system.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...
