Nonlinear vibration of the bevel gear with teeth profile modification
, 2016 The prediction of gear vibration and noise has always been a major concern in gear design. Noise and vibration are inevitable problems that are involved in transmission systems; they have intensified when some nonlinear phenomena such as jump phenomenon,

Interdisciplinary Medicine, EarlyView.Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.

Study on the Design and Modification Method of the Cycloid Gear Tooth Profile
Jixie chuandong, 2019 A new tooth profile curve equation of the cycloid gear is proposed based on the gear meshing transmission principle. Due to the problem that complex cycloid equation is difficult to be substituted directly with the software for modeling, the method of designing the cycloid gear tooth profile curve is obtained by using data fitting.

Poverty Simulations: Are the Learning Outcomes Consistently and Uniformly Positive?
Journal of Dental Education, EarlyView.ABSTRACT Objectives Research indicates significant improvement in average attitudes toward those in poverty following poverty simulations, but little research addresses whether students benefit uniformly. This study measured variability in poverty attitude change following poverty simulations and tested whether poverty attitudes are associated with ...
