L-selectin is a calcium-dependent lectin on leukocytes mediating leukocyte rolling in high endothelial venules and inflamed microvessels. Many selectin ligands require modification of glycoproteins by leukocyte core2 beta1,6-N-acetylglucosaminyltransferase (Core2GlcNAcT-I). To test the role of Core2GlcNAcT-I for L-selectin ligand biosynthesis, we investigated leukocyte rolling in venules of unt...

OBJECTIVES P-selectin binding to P-selectin glycoprotein ligand-1 (PSGL)-1 mediates leukocyte rolling under conditions of inflammation and injury. The aims of this study were to develop an efficient, high temporal resolution model for direct simulation of leukocyte rolling and conduct a study of load-bearing bonds using the model. MATERIALS AND METHODS A stochastic pi-calculus-driven event-tr...

The purpose of this study was to compare the difference between the rolling toothbrushing motion a newly designed brushing machine and three subjects who were skilled in the rolling toothbrushing technique. The evaluation of the distortion curves of the rolling toothbrushing motion recorded by a tri-axial strain gauge attached to the shank of the toothbrush indicate the newly designed brushing ...

Steel rolling process control is the key working procedure of the steel yield process, and that the control of the rolling process is the important factor to affect the quality and cost of the product. This paper is focus on the mill control. Firstly, the model of the mill is founded by exponential smoothing. Then, the method of self-learning optimization can be used to control the model. The o...

This paper features a statistical analysis of the monthly three factor Fama/French return series. Rolling OLS regressions explore relationship between 3 factors, using data from July 1926 to June 2018, available on French’s website. The results suggest there are significant and time-varying relationships factors. A sub-sample 1990 2018 is used analyze series two-stage least squares Hausman test...

We consider the problem of a sphere rolling on a curved surface and solve it by mapping it to the precession of a spin 1/2 in a magnetic field of variable magnitude and direction. The mapping can be of pedagogical use in discussing both rolling and spin precession. As an interesting example we show that the Landau-Zener problem corresponds to the rolling of a sphere on a Cornu spiral, and deriv...
