Intrinsically disordered proteins or intrinsically protein regions comprise a large portion of eukaryotic proteomes (between 35% and 51%). These were found to link with cancer various other diseases. However, widely used additive force field parameter sets are insufficient in quantifying the structural properties proteins. Therefore, we explored systematic correction base set (chosen as Amber ff99SBildn) correct biases that was first demonstrated simulations set. Specifically, φ/ψ...

We propose a scheme of an all-optical transistor based on coupled Bose-Einstein condensate cavity system. The calculated results show that, in such optomechanical system, the transmission probe beam is strongly dependent optical pump power. Therefore, field can serve as ``gate'' transistor, effectively controlling propagation (the ``signal'' field). proposed here may have potential applications communication and quantum information processing.
