Abstract: Embodiments of the present disclosure provide a detachable modular sofa. In at least one embodiment, the detachable modular sofa includes a recliner and a sofa detachably connected to the recliner. The recliner includes a recliner backrest, a recliner side, a recliner bottom and a recliner forepart; between the recliner bottom and the recliner side, a first bottom adjusting bracket is provided. The sofa includes a sofa base and a lift assembly. The lift assembly includes a lift base and a lift bottom, and between the lift base and the lift bottom, a second bottom adjusting bracket is mounted.

Abstract: The present invention discloses a sofa module, including a sofa seat, where a top surface of the sofa seat is provided with at least two splice slots in a region close to each side edge, and a first splice member and a second splice member corresponding to the splice slots, where the first splice member includes a first insertion rod inserted in the splice slot and a first connection rod that has one end connected to the first insertion rod and the other end connected to a back plate; and the second splice member includes a second insertion rod inserted in the splice slot, a second insertion rod configured to be inserted in an adjacent splice slot of the sofa seat, and a second connection rod connecting the second insertion rod to a third insertion rod.

Abstract: Some examples relate to a method for characterizing polynucleotides in a sample. First polynucleotides coupled to a first substrate may be hybridized to second polynucleotides in a sample. First labeled nucleotides may be added to the first polynucleotides using a sequence of the second polynucleotides. A first signal intensity from the first labeled nucleotides is measured. Second labeled nucleotides are added to the first polynucleotides using the sequence of the second polynucleotides. A second signal intensity from the second labeled nucleotides is measured. The first signal intensity is normalized using the second signal intensity. The normalized first signal intensity characterizes the second polynucleotides in the sample.

Abstract: The present disclosure discloses a base, including a front seat, front seat connectors arranged at left and right ends of the front seat, two side seats with a preset interval, and side seat front connectors arranged on the side seats and suitable for being connected to the front seat connectors; each side seat front connector is provided with an assembly base surface; positioning units are arranged on the assembly base surfaces; each front seat connector is provided with an assembly fitting surface making contact with the corresponding assembly base surface; positioning cutoffs for limiting final assembly positions of the front seat connectors on the side seat front connectors are arranged on the assembly fitting surfaces; and first guiding pathways and second guiding pathways for guiding the positioning units to reach the positioning cutoffs in a first assembly direction and a second assembly direction are arranged on the assembly fitting surfaces.
