Harrison, Reid R. | Analog VLSI implementation of a visual interneuron: enhanced sensory processing through biophysical modeling | Flies are capable of rapid, coordinated flight through unstructured environments. This flight is guided by visual motion information that is extracted from photoreceptors in a robust manner. One feature of the fly's visual processing that adds to this robustness is the saturation of wide-fi_x000... | | 1999-01-01 |

Liu, Feng | Anisotropic strain enhanced hydrogen solubility in bcc metals: the independence on the sign of strain | When an impurity is doped in a solid, it inevitably induces a local stress, tending to expand or contract the lattice. Consequently, strain can be applied to change the solubility of impurity in a solid. Generally, the solubility responds to strain ‘‘monotonically,'' increasing (decreasing) with... | | 2012-01-01 |
