This paper establishes nonlinear dynamic equation based on the consideration of elastic deformation of shaft which happens in gear meshing process.In addition, the stiffness incentive, error incentive and external incentives caused Rod Holders by eccentric phenomenon during the process are analysed.The Newmark algorithm is also been used.Then the d
Summary: Background: Continued phenotyping and ongoing molecular epidemiology are important in current and future monitoring of emerging SARS-CoV-2 lineages.Herein we developed pragmatic strategies to track the emergence, spread and phenotype of SARS-CoV-2 variants in Australia in an era of decreasing diagnostic PCR testing and focused cohort-based
