Sub-threshold operation is an efficient solution for ultra low power applications. However, it is very sensitive to process variability which can impact the robustness and effective performance of the circuit. On the other hand this sensitivity decreases as we move towards near-threshold operation. In this paper, the impact of variability on sub-threshold and near-threshold circuit performance ...

Despite the heterogeneity of ideas regarding the definitions of genre, there are also common instances shared among scholars interested in particular aspects of the notion. Swales (1990) and Bhatia (1993) are primarily interested in the sociological and psychological aspects of genre's functioning and construction, respectively.. Swales analyzes the genre of 'article introduction', into four ge...

We show that the space of rooted tree-based phylogenetic networks is connected under nearest-neighbour interchange (rNNI) moves.

We show that drought-induced changes in the intensity of riots lead to moves towards democracy in sub-Saharan Africa, and that these changes are often a result of concessions made as a result of the riots. This provides evidence that low-intensity conflict can have a substantial short-run impact on democratic change, and supports the “window of opportunity” hypothesis: droughts lead to an incre...
