Derivation of the Camassa-Holm equations for elastic waves [PDF]
In this paper we provide a formal derivation of both the Camassa-Holm equation and the fractional Camassa-Holm equation for the propagation of small-but-finite amplitude long waves in a nonlocally and nonlinearly elastic medium.

Effect of nitrogen content on the hot deformation behavior of 0Cr16Ni5Mo martensitic stainless steel
The hot deformation behavior of 0Cr16Ni5Mo martensitic stainless steel with different nitrogen contents was studied on a Gleeble3800 thermal machine. The true strain-stress curves and deformed microstructures of the tested steels were investigated.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
