In this article, we present ultralow leakage logic circuits by combining 3-D memristors with CMOS transistors. Significant current reductions of up to 99% are found experiments and simulation for a memristive hybrid-inverter if compared conventional inverter. Likewise, circuit simulations hybrid ring oscillators, NAND, or full adders show more than 100% gain in energy efficiency per cycle over ...

BACKGROUND Sub-threshold depression is common, impairs functioning, and increases the risk of developing major depression. Although psychological treatments have been investigated for sub-threshold depression, they are costly. A less costly alternative could be an educational health promotion campaign about effective self-help for depression symptoms. The aim of the study is to test the efficac...
