Abstract: Provided herein is a method and system for analyzing a sample. In some embodiments the method makes use of a plurality of capture agents that are each linked to a different oligonucleotide and a corresponding plurality of labeled nucleic acid probes, wherein each of the labeled nucleic acid probes specifically hybridizes with only one of the oligonucleotides. The sample is labeled with the capture agents en masse, and sub-sets of the capture agents are detected using iterative cycles using corresponding subsets of the labeled nucleic acid probes.

Abstract: A wheel comprising a hub element, a rim element, a plurality of substantially circular bands of flexible material spaced about the hub element interposed between and bearing against both of the elements, the axes of the bands being parallel to the axes of the elements, and fastening devices fastening the bands of flexible material to the elements, each fastening device being mounted at its end portions on one of the elements and at its mid-portion engaging one of the bands on the inner peripheral surface thereof only to clamp the band against the element, the bands of flexible material being spaced apart so as at all times to act freely individually and flexing to provide a cushioning effect when the wheel rolls over rough terrain.
