A system for efficient isolation of backup versions of data objects affected by malicious software includes one or more processors and a memory coupled to the processors. Typically, the water-soluble polymer is poly or a derivative thereof. The first electrode stripes and the second electrode stripes are disposed between the display panel and the first substrate, and are electrically independent from each other. The excess branch and the working branch are interlinked at the respective outputs of the two fluidic outputs of the fluidic resistances by a cross-branch.
