A non-Newtonian numerical solution system for the transient thermo-elastohydrodynamic lubrication (TEHL) model has been proposed for a helical gear pair with the finite line contact theory.This model is used to comprehensively show the transient effect, 112 temperature effect, operating condition and the non-Newtonian behaviors on the lubricating p
We construct a mathematical model to quantify the loss of resilience in collapsing honey bee colonies due to the presence of a strong Allee effect.In the model, recruitment and mortality of adult bees have substantial social components, with recruitment enhanced and mortality reduced by additional adult bee numbers.The result is an Allee effect, a
The real-time tension monitoring of wire ropes is a universal way to judge whether the hoist is overloaded in the special working environment of the coal mine.However, due to the strong drafts, unevenness of guide and flexible vibration of wire ropes, it is a challenge to monitor the tension with high accuracy.For this purpose, a new type of acoust
Abstract Numerous studies have evaluated the use of single nucleotide Floor Lamp polymorphism array (SNP-array) in prenatal diagnostics, but very few have evaluated its application under different risk conditions.Here, SNP-array was used for the retrospective analysis of 8386 pregnancies and the cases were categorized into seven groups.Pathogenic c
