Ecological environment change and its effect on Siberian White Crane migration in Zhalong Nature Reserve;

Migration,Colonization and Tissue-repairing Effect of Marrow Mesenchymal Stem Cells in Brain Tissues of Rats with Cerebral Ischemia-Reperfusion Injury;

Role of Tissue Factor Pathway Inhibitor-2 in Ovarian Tumor Migration and Invasion;

Dangxiang people migrated to the interior of China under the attack of the Tibetans.

Qiang people migrated to the interior of China under the oppression of the ruling class during Qin and Han Dynasties.

we adopted such ways as the village investigation,literature and logical-inference to research and analyze the present situation and development of the migrated Mongolian nationality\'s traditional sports.

Methods We cultured human umbilical vein endothelial cells(HUVEC) and differentiated them into Td-ECs after co-cultured with supernatants of A549 cells,and identifid HUVEC with observation and fluorescence staining Ⅷ-related antigen,examined its cell biological characteristics in vitro with the cell migration assay,transmission electron microscopy(TEM) and flow cytometry assay.

In order to study the failure of IC devices induced by the stress in VLSI metal interconnect, In-situ observation of the stress changes of VLSI Al interconnect was studied under the electromigration and thermal conditions by using a synchrotron radiation x-ray diffraction technique.

In many issues of the reliability of copper interconnection, we place the emphasis on electromigration and stress migration.
