A labeling device is provided which is especially designed for use as a transverse labeler with in-line packaging machines. The method uses a defect etchant with a high-defect selectivity in Si. A deformable-mirror holder is provided comprising a body with a central aperture for receiving a deformable mirror, the central aperture being defined by a plurality of flexible beams, with each flexible beam having an end shaped to provide a supporting surface and a flexible portion that connects the beam’s end to the holder’s body. The anti-viral and immune-supporting composition of this invention can perhaps be the sole basis of treatment where affordability is an issue. According to another example, a network node may transmit an overhead message including a corresponding sector indicator and sequence numbers. The method and test strip include a detectable component, such as a gold particle, that is linked to a binder, such as an antibody, through a linkage.
