Structural Design and Performance Analysis of Novel Torsional Impact Tool
Shiyou jixie, 2017 The existing impact and rotary-impact rock breaking technology mostly use the axial impact and the shear action of the PDC bit to achieve high-efficiency rock breaking, but excessive axial force will cause the failure of PDC bit shear force, resulting in

A digital twin for torsional vibrations of power plant turbogenerators
Turbogenerators are important mechanical and electrical components in power plants. The steam turbines convert thermal energy into mechanical energy causing the rotor to spin. And the generator produces electrical energy by electromechanical interactions.

A sequence environment modulates the impact of methylation on the torsional rigidity of DNA
Chemical Communications, 2018 We explain, with atomic-level detail, how DNA methylation may contribute to the regulation of biological processes. We show that DNA sequence environment modulates the impact of methylation on the physical properties of the double helix.
