The stabilities and electronic/band structures of single-layer bismuth oxyhalides have been investigated by employing first-principles calculations. The results indicate that the single-layer bismuth oxyhalide materials, except for BiOF, have robust energetic and dynamical stabilities because of their low formation energies and the absence of imaginary(More)
BACKGROUND Tim4 is a transmembrane protein known as T cell immunoglobulin and mucin domain containing protein-4. We speculated that Tim4 might be associated with glioma. This study aimed to investigate the expression level of Tim4 in gliomas and the regulatory role of Tim4 on the growth and apoptosis of LN-18 glioma cells. MATERIAL/METHODS Tumor tissues(More)
For the C title of 2012 China Undergraduate Mathematical Contest in Modeling, the influential factors of stroke are analyzed. Using the data in Appendix-C1, a statistical description of the patients is made by EXCEL. And then combined with the climate data in Appendix-C2, several mathematical models are established to analyze the relationship between stroke(More)
