Soluble Jagged 1/Fc chimera protein induces the differentiation and maturation of bone marrow-derived dendritic cells
A soluble Jagged 1/Fc chimera protein (Jagged 1/Fc) was directly used to induce differentiation and maturation of bone marrow-derived dendritic cells (DCs) in mice in vitro. A model of inducing and amplifying DCs...

Numerical study on effects of door-opening on airflow patterns and dynamic cross-contamination in an ISO class 5 operating room
The contamination diffusion to the operating room when the door is open was simulated with a computational fluid dynamic(CFD) method, to give the extent of the contamination diffusion. The influence of the doo...

Influence of surface passivation on the minority carrier lifetime, Fe-B pair density and recombination center concentration
Three kinds of methods (0.08 mol/L iodine in ethanol, SiN x :H, and 40% HF) are used to passivate solar-grade Czochralski (Cz) silicon wafers. Thereafter, minority carrier lifeti...
