PRC2.1 Coordinates Peri‐Nucleolar H3K27me3‐Enriched Heterochromatin Organization and NPM1 Pentamerization to Maintain Nucleolar Integrity

Advanced Science, EarlyView.
PRC2.1(PCL2)‐coordinated H3K27me3‐enriched PNH establishes a spatial scaffold crucial for nucleolar integrity. As a crucial coordinator, PCL2 links PRC2.1 to chromatin organization and NPM1 assembly. This network‐based model reveals how chromatin modifications and nucleolar components cooperatively maintain nucleolar architecture, revealing novel ...

Influence of the Lubricant Temperature of Splashed Lubricated Worm Gearbox on Churning Power Losses

ITEGAM-JETIA
The primary goal of lubricating a worm gearbox is to encourage sliding between teeth, which lowers the coefficient of friction and regulates the temperature rise brought on by rolling and sliding friction. Due to both non-load-dependent and load-

Simulated and measured characteristics for churning oil flow with a coating surface over a wide range of temperatures

Friction
Gearbox efficiency is essential for new energy vehicles. Most of the energy in a gearbox is consumed by a load-independent factor, e.g., churning loss, which, however, has not been deeply addressed. In this study, load-independent losses are inhibited by
