The Nile grass rat (Arvicanthis niloticus) has a high proportion of cone photoreceptors (≈30-40%) compared to that in the common laboratory mouse and rat (≈1-3%), and may prove a preferable murine model to study cone-driven information processing in retina and primary visual centers. However, other than regions involved in circadian ...

Further improvement of phase change memory devices based on Ge-Sb-Te alloys imposes the reduction of the active cell dimensions to the nanoscale. We investigate the atomic arrangement of Ge(1)Sb(2)Te(4) and Ge(2)Sb(2)Te(5) nanowires. We identify the stacking sequence in each crystal structure by combining the direct observation by High Angle Annular ...
