Mimicking DOUGONG brackets orchestrate regulating inflammation and mechanical stimuli for osteochondral regeneration using 3D printing

open access: yesInterdisciplinary Medicine, EarlyView.
Akermanite scaffolds promote osteogenic differentiation of BMSCs through regulating the PI3K/Akt signaling pathway, and strontium ions enhance the akermanite effects by mediating the cytokine‐cytokine receptor interaction pathway. Thus, the enhancements of osteogenesis in subchondral bone coupled with the chondral‐promoting effects of chondrocytes ...

Launch Uncertainty Analysis Under Barrel Erosion Using Experiments and Random Matrix Theory

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The effects of barrel erosion on artillery firing performance have long been a subject of concern, but its effect on launch uncertainty has yet to be investigated. This article explores the influence of barrel erosion on the interior ballistic mechanical properties and launch disturbances.

Dynamic Behavior of a Two‐Degree‐of‐Freedom System With Electromagnetic Interaction via a Skew‐Symmetric Matrix

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This paper analyzes the dynamic behavior of a two‐degree‐of‐freedom system subjected to electromagnetic interaction modelled through a skew‐symmetric coupling matrix. The system comprises two mechanically independent oscillators coupled by velocity‐dependent electromagnetic forces.

Influence of vibrations on structures [PDF]

open access: yes, 2018
One type of occasional structural load is a seismic load. Earthquakes and blasts are typical sources of vibrations, but vibration generated during urban tunnel construction can represent a significant problem.
