under both quasi-static loading and dynamic loading. The foams studied show a significant strain rate sensitivity, the flow strength can be improved as much as 112%, and the cell size also has a sound influence on the strain rate sensitivity of the foams. The foams of middle cell size exhibit the highest elastic modulus, the highest flow strength and the most significant strain rate sensitivity. Key......

through 209 sets of rock burst samples from underground rock projects. The sensitivity of indicators is analyzed and 209 sets of rock burst samples are discriminated by this model. The discriminant results of the entropy-cloud model are compared with those of Bayes, KNN and RF methods. The results show that the sensitivity order of those factors from high to low is sq /sc, sq, Wet, sc/st, st , sc......
biosensor screening methodology described here has been established for sensitive detection of D-Ala-D-Ala-containing peptides and vancomycin immobilized on the surface. Due to high sensitivity, lower... R, NARANG S A, YOUNG N M.

Trans. Nonferrous Met. Soc. China 23(2013) 1646-1651 Loading rate sensitivity of nanoindentation creep behavior in a Fe-based bulk metallic glass Fu XU, Zhi-lin LONG, Xu-hui DENG, Ping ZHANG College.... As the indentation loading rate increases from 1 mN/s to 50 mN/s, the stress exponent decreases gradually from 28.1 down to 4.9, exhibiting significant indentation loading rate sensitivity. Finally......
