TL;DR: A radial clearance adjustable bearing is proposed in this paper, which can change the dynamics characteristics of the bearing by adjusting the radial clearance, and the amplitude response of the system decreases almost equally in the vertical and horizontal directions.

TL;DR: In this paper, a new method for modeling a rod and wire continuous rolling process is presented, which consists of a pushing technique of rigid body and a method of data transfer, and it is utilized to analyze the deformation and the temperature distribution of billet during the multi-pass rolling process.

TL;DR: Some biochemical and enzymatic alterations provoked by the stress conditions in the specific case of K. marxianus are confirmed: such as decreases in transcription, translation and oxidative phosphorylation, alterations in cellular fatty acid composition, and increases in the abundance of molecular chaperones and proteasome proteins.

TL;DR: A geographical map based on available data during 1987–2015 showed wide variations of periodontal disease across the mainland China, and further high-quality epidemiological studies with standardized diagnostic criteria are needed.

TL;DR: Rural MSM is a distinctive and complex population with multiple identities in China and Concurrent multiple sexual partnerships, high mobility and low disclosure rate are the major challenges for HIV prevention and intervention programs in MSM.
