Abstract: A system may include a display and a processor communicatively coupled to the display. The processor may be configured to: output, to the display, a synthetic vision system (SVS) taxi mode exocentric view of an aircraft when the aircraft is performing taxi operations and when the aircraft is on ground; receive a user input to switch the output of the SVS taxi mode exocentric view to an SVS flight mode egocentric view from the aircraft; and switch the output of the SVS taxi mode exocentric view to output, to the display, the SVS flight mode egocentric view when the aircraft is performing taxi operations and when the aircraft is on ground based at least on the user input to switch from the SVS taxi mode exocentric view to the SVS flight mode egocentric view.

Abstract: Methods and compositions are provided for gently lysing and solubilizing cells. Methods and compositions are further provided for quickly purifying high quality low molecular weight nucleic acid from host cells. Target cells are treated with a pre-chilled lysis solution having a zwitterionic detergent, for example n-Dodecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate, and a brief room-temperature incubation. Where nucleic acid purification is required, the lysis solution-treated cells are contacted with a nucleic acid capture matrix having an average pore size of at least about 1 ?m.
