Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears

open access: yes, 1990
A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile

Nonlinear vibration of the bevel gear with teeth profile modification

open access: yes, 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,

Ordered assembly of Cas12a for better performance of CRISPR/Cas system with application to the diagnosis of dental caries

open access: yesInterdisciplinary 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.

Analysis of Meshing Performance for Equal Base Circle Bevel Gear

open access: yesJixie chuandong, 2019
In order to analyze the bearing capacity and transmission performance of equal base circle bevel gear under actual working conditions, the tooth contact analysis (TCA)is performed to simulate the tooth surface contact pattern and transmission error ...

Study on the Design and Modification Method of the Cycloid Gear Tooth Profile

open access: yesJixie 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?

open access: yesJournal 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 ...

Generative Artificial Intelligence–Driven Clinical Case Simulation in Temporomandibular Disorder Education: ChatGPT Versus Real Patients

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Background Temporomandibular disorders (TMDs) and orofacial pain (OFP) demand advanced diagnostic and clinical reasoning skills in dental education. Traditional simulations with real patients face limitations in availability and standardization.
