In this study, the putative involvement of the Notch-1 signaling pathway in the neuronal differentiation of bone marrow mesenchymal stem cells (BMSCs) was investigated through RNA interference (RNAi). We found that mNotch-1shRNA could efficiently block expression of Notch-1 in BMSCs. After induction, immunohistochemistry, reverse transcriptase-PCR and(More)
A network survivability analysis model of Mine Ethernet Passive Optical Network (M-EPON) system in the mine communication was proposed, the topologies of dual-bus and dual ring-shaped network were presented. Also, the network survivability of the traditional tree-shaped and above proposed two different topologies of M-EPON systems was studied respectively.(More)
The transmission characteristics of curved tunnel with arbitrary cross section is analyzed with a combined method which involves staircase approximation, mode matching (MM)/finite element method. The hybrid approach described combines the computational efficiency of the modal analysis with the versatility and flexibility of FEM and can be used to accurately(More)
Stringing haulage motors were main underground conveyance equipments, but they were the strong electromagnetic interference sources. To resolve the problem of monitor system false alarm and mobile communication interruption, the interference generation mechanism and distribution characteristic were analyzed. The means of conducted interference circuit(More)
Inductive components in intrinsically safe instruments have the ability to ignite flammable gas for its energy storage characteristics. Analyzed the way for diode connected in parallel with the inductance to release the energy storing in the inductance, established the equivalent inductor mathematical model with the linear attenuation model of inductive(More)
