The Dynamics of the Working Body of the Tubular Conveyor with the Chain Drive [PDF]
Journal of Applied and Computational Mechanics, 2021 The theoretical calculations of the dynamics of the conveyor drive chain oscillations for different speeds of bulk material movement as a result of motion internal perturbations have been presented in the article. Resonant oscillations have been studied.

Modeling and analysis of chain drive systems [PDF]
The Journal of the Acoustical Society of America, 1990 Chain drive noise caused by meshing between the chain link and the sprocket has been recognized to be an important problem in the design of automotive powertrains. This paper presents a new dynamic model that integrates the local meshing mechanics with the global chain vibration characteristics.

Tailoring short-chain sulfur molecules to drive redox dynamics for sulfur-based aqueous battery
Proceedings of the National Academy of Sciences of the United States of America, 2023 Significance Short-chain sulfur molecules show higher electrochemical reactivity than conventional cyclic S8 molecules owing to efficient redox route. Therefore, they can be considered as ideal active materials in solid–solid redox reaction.

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
