Offset algorithm: is fixed on chips and cannot be changed on CE devices. Device vendors can select and combine hash algorithms and offset values only based on the preceding hash calculation parameters supported by chips. The hash load balancing effect is closely related to the traffic model. For...
Granulocyte colony stimulating factor (G-CSF) is a glycoprotein secreted by endothelial cells, macrophages and other immune cells that functions as a growth factor and cytokine. The functional sites of G-CSF are widespread in the human body; some studies have reported [5,6,7] that the receptor...

There is a public concern that smartphone communication undermines well-being by displacing face-to-face interactions. However, research on this “social displacement hypothesis” has provided mixed results. We examined when this hypothesis holds true (within-persons vs. between-persons) and tested an...
