A large format digital camera has a primary camera system configured for collecting panchromatic image data and a secondary camera system configured for collecting color image data. The end effector includes a tissue-retaining device. The audio processing module or circuit may be operatively connected to an audio input interface and to an output audio interface. The first blade has a cutter force greater than the cutter force of the second blade. The second layer comprises a diesel oxidation catalyst zone and an NO oxidation zone. The reformer includes an electroconductive mixture of active material and a polymeric ceramic material shaped to constitute a slab having an upper surface and a lower surface and grooves along at least one of the upper surface and the lower surface and flat regions along the periphery of the grooved surface.
