A parameter‐preadjusted energy‐conserving integration for rigid body dynamics in terms of convected base vectors
Sign Up to like & getrecommendations! Published in 2020 at "International Journal for Numerical Methods in Engineering"
DOI: 10.1002/nme.6500
Abstract: Energy‐conserving integrations are widely used in long‐time simulations of mechanical systems because they exhibit excellent stability and conserve the discrete energy in conservative systems. However, in many applications, their errors of other quantities, for example,… read more here.

DOI: 10.1016/j.celrep.2019.07.054
Abstract: Proper transcriptome reprogramming is critical for hosts to launch an effective defense response upon pathogen attack. How immune-related genes are regulated at the posttranscriptional level remains elusive. We demonstrate here that P-bodies, the non-membranous cytoplasmic… read more here.

DOI: 10.1103/physrevlett.120.210401
Abstract: The dynamics of bosons in generic multimode systems, such as Bose-Hubbard models, are not only determined by interactions among the particles, but also by their mutual indistinguishability manifested in many-particle interference. We introduce a measure… read more here.
