Long non-coding RNAs (lncRNAs) have been found to play a vital role in several gene regulatory networks involved the various biological processes plants related stress response. However, systematic analyses of lncRNAs expressed rice Cadmium (Cd) are seldom studied. Thus, we presented characterization and expression root development at an early stage response Cd stress.The lncRNA deep sequencing revealed differentially among normal condition. In group, 69 were up-regulated 75 down-regulated....
Scaled ferroelectric transistors (L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">g</sub> =76 nm) in a back- gated configuration are fabricated with channel-last process flow. Using this approach, optimization of the gate oxide film can be decoupled from that semiconductor channel to reduce parasitic interfaces. As result, 3σ memory window for fast programming time 10 ns (including an instantaneous read-after-write) at 1.8 V and high endurance...
