The extracellular signal-regulated kinase (ERK) is a component of the mitogen-activated protein kinase cascade. Exon 2 of erk2 was deleted by homologous recombination and resulted in embryonic lethality at embryonic day 6.5. erk2 mutant embryos did not form mesoderm and showed increased apoptosis but comparable levels of BrdUrd incorporation, indicating a(More)
With the rapid advance of online gaming and virtual reality technology, virtual teamwork has become increasingly popular. People spend more and more time working with others in 3D virtual environments to accomplish common goals. In this study, we investigate the impact of virtual teamwork on collaboration in the real world. We conducted a study with a(More)
—With more and more vehicles equipped with GPS tracking devices, there is increasing interest in building and updating maps using vehicular GPS traces. But commodity GPS devices have lower accuracy and lower sampling frequency, which made it more difficult to infer road network than most existing approaches that using high-precision and high-frequency GPS(More)
This study aimed to evaluate the biological functions of excision repair cross complementation goup 1 (ERCC1) in cell proliferation, cell cycle, invasion and cisplatin response of non-small cell lung cancer (NSCLC) cells. Firstly, ERCC1 gene was successfully transfected into H1299 cells by gene cloning and transfection techniques. Then, cell proliferation(More)
Multiscale distributed fusion estimation is the algorithm of multisensor system, which uses the multiscale analysis establishing the multiscale dynamic models. The result at one given scale is got by observation systems at different scales. Estimating the result to the thinnest scale, the optimal estimation is obtained based on the overall observations and(More)
Acute toxicities of anaerobic ammonia oxidation (ANAMMOX) substrates and four antibiotics from pharmaceutical wastewaters on ANAMMOX process were reported. Individual and joint acute toxicity assays were performed using 50% inhibitory concentration (IC50). Results showed that IC50 values and their 95% confidence interval of ammonium chloride (A), sodium(More)
